The epidemiology of myasthenia gravis.

Abstract: Neuromuscular junction (NMJ) disorders include several dysfunctions that ultimately lead to muscle weakness. Myasthenia gravis (MG) is the most prevalent NMJ disorder with a highly polymorphic clinical presentation and many different faces. Being an autoimmune disease, MG correlates with the presence of detectable antibodies directed against the acetylcholine receptor, muscle-specific kinase, lipoprotein-related protein 4, agrin, titin, and ryanodine in the postsynaptic membrane at the NMJ. MG has become a prototype serving to understand both autoimmunity and the function of the NMJ better. The aim of this review is to synthesize some of the epidemiological data available. Epidemiological data regarding MG are important for postulating hypotheses regarding its etiology and facilitating the description of MG subtypes. Thus, adequate documentation through broad databases is essential. The incidence and prevalence of MG reported around the globe have been rising steadily and consistently over the past decades. Ethnic aspects, gender-related differences, and environmental risk factors have been described, implying that these might contribute to a specific phenotype, further suggesting that MG may be considered an umbrella term that covers several clinical entities.

The effect of ketamine on preventing postpartum depression.

Abstract: Postpartum depression is a common disabling psychosocial disorder that could have adverse effects on the life of the mother, infant, and family. The present study was conducted to evaluate the effect of ketamine on preventing postpartum depression in women undergoing caesarian sections considering the relatively known positive effect of ketamine on major depression. The present double-blind, randomized clinical trial was conducted on 134 women undergoing scheduled caesarian sections. Participants were randomly allocated into two groups of control and intervention. To induce anesthesia, 1-2 mg/kg of body weight of Nesdonal and 0.5 mg/kg of body weight of ketamine were used in the intervention group, while only 3-5 mg/kg of body weight Nesdonal was administered in the control group. Data were gathered using the Edinburgh Postnatal Depression Scale (EPDS) in three stages: before the caesarian section and two and four weeks after the caesarian section. Data were analyzed using variance analysis with repeated measures and the Chi-square test. Results of the present study showed that the mean (± standard deviation) of the depression score in the intervention and control groups were 13.78±3.87 and 13.79±4.78(p = 0.98) before the caesarian section, 11.82±3.41 and 14.34±4.29 (p < 0.001) two weeks after and 10.84±3.48 and 13.09±3.79 (p = 0.001) four weeks after the caesarian section, respectively. Using ketamine in the induction of general anesthesia could be effective in preventing postpartum depression. However, further studies are required to strengthen these findings.

Vitiligo and chronic autoimmune thyroiditis.

Abstract: Vitiligo, the discoloration of the skin, has different autoimmune mechanisms reflected by many biomarkers as shown by skin histology, staining for CD4 and CD8 T lymphocytes, chemokine ligand 9 or circulating cytokines such as interleukin (IL)-1 beta, interferon (IFN)-gamma, transforming growth factor (TGF)-beta, antibodies, markers of oxidative stress, chemokines, and others. In this narrative review, we aim to overview vitiligo in relationship with chronic autoimmune thyroiditis. Regarding vitiligo, more than 50 different genetic loci have been associated with this disease, and the heritability is high. There is a 20% risk of an environmental connection which may also act as a trigger; moreover, the association with human leukocyte antigen (HLA) expression is well recognized. The specific lesions display CD8+ tissue-resident memory T cells as continuous key activators of melanocytes. The association with chronic thyroiditis is based on common autoimmune background and excessive reactive oxygen species that destroy melanocytes and thyrocytes (oxidative stress hypothesis) with thyroxine and melanin as target molecules, thus sharing a common origin: tyrosine. Moreover, common epigenetic anomalies or mutations of the Forkhead transcription factor D3 (FOXD3) have been described. Since vitiligo affects up to 1-2% of the population worldwide and 34% of patients have positive thyroid antibodies, apart from common autoimmunity background and oxidative stress toxicity, the association is clinically relevant for different practitioners.

Low-level laser therapy in temporomandibular joint disorders: a systematic review.

Abstract: Temporomandibular joint disorders (TMDs) encompass a wide array of ailments affecting the temporomandibular joint (TMJ), muscles of mastication, and the allied structural framework. Myofascial pain, internal derangement of the joint, and degenerative joint diseases constitute the majority of TMDs. TMDs usually have a multifactorial etiology, and treatment modalities range from conservative therapies to surgical interventions. Low-level laser therapy (LLLT) has evolved as an efficient non-invasive therapeutic modality in TMDs. Previously conducted systematic reviews and meta-analyses have shown variable results regarding the efficiency of LLLT in TMJ disorder patients. Hence, this systematic review was carried out as an attempt to evaluate the efficacy of LLLT in the treatment of temporomandibular joint disorder patients.

Security challenges and solutions using healthcare cloud computing.

Abstract: Cloud computing is among the most beneficial solutions to digital problems. Security is one of the focal issues in cloud computing technology, and this study aims at investigating security issues of cloud computing and their probable solutions. A systematic review was performed using Scopus, Pubmed, Science Direct, and Web of Science databases. Once the title and abstract were evaluated, the quality of studies was assessed in order to choose the most relevant according to exclusion and inclusion criteria. Then, the full texts of studies selected were read thoroughly to extract the necessary results. According to the review, data security, availability, and integrity, as well as information confidentiality and network security, were the major challenges in cloud security. Further, data encryption, authentication, and classification, besides application programming interfaces (API), were security solutions to cloud infrastructure. Data encryption could be applied to store and retrieve data from the cloud in order to provide secure communication. Besides, several central challenges, which make the cloud security engineering process problematic, have been considered in this study.

Analysis of the transcriptional activity of genes of neuropeptides and their receptors in the blood of patients with thyroid pathology.

Abstract: The thyroid hormone plays a vital role in the development and maturation of the nervous system not only during prenatal and perinatal age but also in adults. "Peripheral marker hypothesis" revealed that gene expression changes in some regions of the brain are reflected into the peripheral blood lymphocytes. The objective of the study was to investigate changes in the gene expression profile of neuropeptides and their receptors in patients with different forms of thyroid pathology. One hundred fifty-three patients with thyroid pathology were enrolled in the study. They were divided into three groups: group 1 included 16 patients with postoperative hypothyroidism, group 2 included 65 patients with hypothyroidism resulting from autoimmune thyroiditis (AIT), and group 3 included 72 patients with AIT and elevated levels of anti-thyroglobulin (anti-Tg) and anti-thyroid peroxidase (anti-TPO) antibodies in the serum. We used a pathway-specific polymerase chain reaction (PCR) array (RT2 Profiler™ PCR Array Human Neurotrophins & Receptors, QIAGEN, Germany) to identify and verify neuropeptides and receptors pathway-focused gene expression in 12 individuals that were randomly selected from each group using real-time PCR. Our research identified that patients with postoperative hypothyroidism had a considerably increased expression of NPY1R, NTSR1, and NPY4R. The patients with hypothyroidism caused by autoimmune thyroiditis had considerably lower expression of NTSR1, while the expression of NPY1R increased. The mRNA levels of NPY2R and PNOC increased in the patients with elevated levels of autoantibodies anti-Tg and anti-TPO in the serum, and mRNA levels of NPY1R and NTSR1 decreased in this group of patients.

The use of mobile health interventions for gestational diabetes mellitus: a descriptive literature review.

Abstract: This study attempted to review the evidence for or against the effectiveness of mobile health (m-health) interventions on health outcomes improvement and/or gestational diabetes mellitus (GDM) management. PubMed, Web of Science, Scopus, and Embase databases were searched from 2000 to 10 July 2018 to find studies investigating the effect of m-health on GDM management. After removing duplications, a total of 27 articles met our defined inclusion criteria. m-health interventions were implemented by smartphone, without referring to its type, in 26% (7/27) of selected studies, short message service (SMS) in 14.9% (4/27), mobile-based applications in 33.3% (9/27), telemedicine-based on smartphones in 18.5% (5/27), and SMS reminder system in 7.1% (2/27). Most of the included studies (n=23) supported the effectiveness of m-health interventions on GDM management and 14.3% (n=4) reported no association between m-health interventions and pregnancy outcomes. Based on our findings, m-health interventions could enhance GDM patients' pregnancy outcomes. A majority of the included studies suggested positive outcomes. M-health can be one of the most prominent technologies for the management of GDM.

Rapid diagnostic methods for SARS-CoV-2 (COVID-19) detection: an evidence-based report.

Abstract: Since December 2019, the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has been a global health concern. The transmission method is human-to-human. Since this second wave of SARS-CoV-2 is more aggressive than the first wave, rapid testing is warranted to use practical diagnostics to break the transfer chain. Currently, various techniques are used to diagnose SARS-CoV-2 infection, each with its own set of advantages and disadvantages. A full review of online databases such as PubMed, EMBASE, Web of Science, and Google Scholar was analyzed to identify relevant articles focusing on SARS-CoV-2 and diagnosis and therapeutics. The most recent article search was on May 10, 2021. We summarize promising methods for detecting the novel Coronavirus using sensor-based diagnostic technologies that are sensitive, cost-effective, and simple to use at the point of care. This includes loop-mediated isothermal amplification and several laboratory protocols for confirming suspected 2019-nCoV cases, as well as studies with non-commercial laboratory protocols based on real-time reverse transcription-polymerase chain reaction and a field-effect transistor-based bio-sensing device. We discuss a potential discovery that could lead to the mass and targeted SARS-CoV-2 detection needed to manage the COVID-19 pandemic through infection succession and timely therapy.

The role of novel poly (ADP-ribose) inhibitors in the treatment of locally advanced and metastatic Her-2/neu negative breast cancer with inherited germline BRCA1/2 mutations. A review of the literature.

Abstract: The use of the PARP inhibitors (PARPi) in the treatment of breast cancer (BC) with germine mutations has evolved over the years, and further research has been done in order to broaden the horizon of this treatment strategy. Therefore the aim of this paper is to review the efficiency of PARPi in the treatment of BRCA 1/2-mutated locally advanced and metastatic Her-2/net negative BC mentioning their side effects, mechanism of resistance and future directions. Inhibition of PARP transforms single-strand breaks into double-strand breaks (DBS), the accumulation of the latter causing cell death (cell apoptosis). The Olympia AD phase III trial demonstrated a statistically significant progression-free survival rate (PFS) when using the PARPi olaparib in metastatic BC with germline BRCA1/2 mutations without any benefit of the overall survival rate. PARPi therapy is associated with acceptable responsive rates and progression-free survival rates in locally advanced and metastatic BRCA1/2 associated BC through mechanisms that enhance and increase the sensitivity to chemotherapeutic or target agents as they induce a synthetic lethality and cell apoptosis. The side effects are not significant, the most adverse effects being related to the hematological and gastrointestinal systems. Olaparib is currently approved in the first-line treatment of BRCA1/2 mutated Her-2/neu negative metastatic BC at an oral dose of 300 mg twice daily, while Talazoparib represents a category one recommendation in locally advanced and metastatic Her-2/neu negative BC in women with central nervous system metastases.

A review of peripherally inserted central catheters and various types of vascular access in very small children and pediatric patients and their potential complications.

Abstract: Accessing the veins for blood delivery, sampling or nutrition is a critical factor in the process of care and management of pediatric patients. In this regard, the peripherally inserted central catheter (PICC) is one of the main alternatives which could be applied effectively as traditional central venous devices in neonates and adults. Due to their essential role in providing safe central venous entry, PICCs could be applied extensively in patients who are critically ill. The main aims of the present study are to review approximately all relevant publications concerning PICC procedures, any possible complications, and the most appropriate decision for preventing these complications due to their high mortality rate. We carried out a comprehensive search on PubMed, HubMed, EMBASE, MEDLINE, Science Direct, Scopus, MEDLINE, and EMBASE databases for identifying the most relevant publications related to potential complications following the application and insertion of PICCs in hospitalized children and infants. Through appropriate care of catheters, the rate of possible infectious, mechanical and thrombotic complications would decrease considerably compared to those patients who received traditional central venous catheters. However, the process of vascular access in neonatal and children is very challenging. Any delay or denying treatment due to the lack of vascular access is intolerable. In this regard, anesthesiologists must achieve extra knowledge of various vascular devices.

Neurological complications in COVID-19 - a diagnostic challenge.

Abstract: With the exponential growth of COVID-19 cases, the neurological complications reported during or after the infection became more common. There is limited knowledge regarding the pathophysiological mechanisms that are responsible for these complications. Recent data provides compelling evidence for the neurotropic nature of SARS-CoV-2, based on neurological manifestations reported during the current pandemic, as well as on previous experience with other coronaviruses. We present the case of a patient who developed headaches, motor deficit and dysphasia after respiratory COVID-19. Imaging tests showed heterogeneous central nervous system lesions (multiple subarachnoid hemorrhages and two ischemic strokes). Given the plethora of atypical neurological complications of COVID-19 described in the current literature, establishing a positive diagnosis and deciding on a treatment plan proved to be particularly challenging. We set to discuss some of the possible pathologies, hypothesized to be associated with COVID-19, that could lead to concomitant neurological lesions, similar to those noticed in our patient.

Management strategies and clinical follow-up of pregnant women with intracranial meningioma.

Abstract: Meningiomas are common primary tumors of the central nervous system. The incidence at the age of fertility is low, although there are some hormonal mechanisms involved. Growth in size was observed during the luteal phase of the menstrual cycle, which could lead to developing new symptoms during pregnancy or worsening of the already existing ones. Visual impairment is the chief complaint, followed by headache, nausea, vomiting, and seizures. Diagnosis is based on neurological examination, ophthalmoscopy, imaging techniques like gadolinium-enhanced magnetic resonance imaging (MRI), and contrast-enhanced computed tomography (CT) scans, bearing in mind the patient's irradiation and prejudice on the fetus together with the histopathological examination. The objective of the review is to determine the influence of meningioma on pregnancy and vice-versa and provide a strategy of follow-up for maternal-fetal specialists and not only. We performed a systematic review by searching relevant information in PubMed and Wiley databases using keywords as meningioma, pregnancy, progesterone receptors. The results showed that besides a similar incidence of meningioma in pregnant and non-pregnant women, symptoms might flare during pregnancy due to water retention, engorgement of vessels, and the presence of sex hormone receptors on tumor cells. Meningioma may impact the route of pregnancy with adverse effects on the fetus. Thus, fetal monitoring by biophysical profile and cardiotocography (CTG) is needed. The preferred treatment option is surgery, but gestational age and the woman's status must be taken into consideration.

Single-use ureteroscopes in ectopic pelvic kidney stones.

Abstract: We analyzed the results of single-use flexible ureteroscopy (su-fURS) with the holmium laser in treating renal stones associated with ectopic pelvic kidney (EPK). The study retrospectively analyzed data of 11 patients diagnosed with EPK and stone disease who underwent su-fURS between May 2017 and November 2019. The analyzed surgical data included the mean operation time, stone-free and complication rates, as well as hospitalization period. Disposable digital flexible ureteroscopes were exclusively used. The mean age was 55, with a 1.2:1 male to female ratio. The mean stone burden was 30±9 mm (ranging from 17 to 49 mm). The mean calculi digitized surface area (DSA) was 299±56 mm2 (ranging from 170 to 597 mm2). A ureteral access sheath was used in all 11 patients, and holmium laser lithotripsy was performed (dusting mode parameters: low energy - 0.5J, high frequency - 50 Hz, long pulse; pop-corn mode: high energy >1 J, medium frequency- 10-50 Hz, long pulse; fragmenting mode: high energy >1 J, low frequency <10 Hz, short pulse). The average operative time was 78±19 minutes (ranging from 68 to 144 minutes). The stone-free status (residual fragments <3 mm) after one session was 60.1%, 84.1% after the second session, and 94.4% after the third session. The hospitalization period was 29 hours (ranging from 17 to 39 hours). The overall complications rate (according to the Clavien-Dindo system) was 19.7%. Therefore, su-fURS represents an effective therapeutic approach characterized by a remarkably high stone-free rate and few complications in EPK-associated calculi.

Perceived barriers to early mobilization of intensive care unit patients by nurses in hospitals affiliated to Jundishapur University of Medical Sciences of Ahvaz in 2019.

Abstract: Early mobilization (EM) of patients in the intensive care unit (ICU) is a safe, feasible, and beneficial approach. However, the implementation of EM as a part of routine clinical care can be challenging. As a result, the present study aimed to identify the potential barriers to EM of ICU patients. The statistical population of this descriptive-analytical study included 107 critical care nurses working in hospitals affiliated with the Jundishapur University of Medical Sciences of Ahvaz. The participants were selected using the census method among the eligible critical care nurses, and the researcher-made questionnaire was used for data collection. This questionnaire included a demographic questionnaire and an inventory of barriers to EM. In total, 72% of the nurses had a highly positive attitude towards EM implementation, whereas relatively few had a slightly positive attitude. The major human-resource-related barriers included the lack of trained staff (76.6%), inadequate shift nurses (74%), and inadequate time for this procedure (57.9%). Approximately 88.9%, 82.2%, 62%, and 57.9% of the nurses reported coma or a deep degree of sedation, mobilization of obese patients, mobilization of patients with agitation, and pain, respectively, as the major patient-related barriers. The lack of EM implementation and recording according to the checklist (90.4%), the lack of an approved EM implementation protocol (88.8%), and inadequate equipment for the mobilization of mechanically ventilated patients (58%) were among the major equipment-related barriers. The participating nurses were aware of the EM advantages, and the majority of them had a highly positive attitude towards its implementation in the ICU. However, nurses believed that the actual EM implementation is associated with challenges such as human resources limitations, equipment-related barriers, and patient-related barriers.

Clinical features and genetics in non-5q spinal muscular atrophy caused by acid ceramidase deficiency.

Abstract: Spinal muscular atrophy (SMA) is a spectrum of genetically and clinically heterogeneous diseases leading to the progressive degeneration of peripheric motor neurons with subsequent muscle weakness and atrophy. More than 95% of the cases of SMA are represented by homozygous mutations of the SMN1 gene (5q-SMA). Because this disease represents the leading cause of death due to a genetic cause and due to the availability of genetic therapies which can now save the life of the patient and stop the progress of the disease, early diagnosis is crucial. This report presents the case of a 13-year-old patient admitted to our hospital in 2018 who presented a phenotype typical to 5q-SMA. Next-generation sequencing (NGS) and Sanger sequencing of the SMN1 gene were performed, and a negative result was obtained. Consequently, we continued testing using whole-exome sequencing and discovered three mutations in the ASAH1 gene (one pathogenic and two variants of uncertain significance). Pathogenic mutations in the ASAH1 gene are responsible for spinal muscular atrophy with progressive myoclonic epilepsy (SMA-PME) and Farber disease, which overlapped with our patient's phenotype. Currently, there are 45 SMA cases caused by mutations in the ASAH1 gene reported worldwide; however, the present case is the first reported in Romania.

Romanian National premiere with the new Thulium SuperPulsed Laser in the endourological treatment of urolithiasis.

Abstract: In this paper, we aimed to verify the efficiency and functionality of the new Soltive Thulium Fiber Laser (TFL) in the treatment of urinary stones. The Soltive Laser System was used in 17 urolithiasis cases: 10 renal, 5 ureteral, and 2 bladder stone patients. The average stone size was 13.1 mm (ranging between 11-29 mm) for the kidney, 8 mm (ranging between 6-12 mm) for the ureter, and 31 mm (ranging between 27-34 mm) for the bladder. Only single calculi patients were included in the study. We used 100 and 150 μm core-diameters fibers (CDF). Three settings were applied: 0.15 J/100 Hz for "fine dusting", 0.5 J/30 Hz for "dusting" and 1 J/15 Hz for the fragmentation mode. The mean operative time was 34 minutes for renal, 21 minutes for ureteral, and 39 minutes for bladder stones. The visibility was optimal in all cases. The stone-free rate at 1 month after treatment was 95% for renal calculi and 100% for ureteral and bladder stones. Very fine dust made of stone fragments smaller than 1 mm in size that passed spontaneously through the access sheath was observed, especially subsequent to the "fine dusting" mode. The complication rate was very low: 1 patient was classified as Clavien grade 1 and 1 patient as Clavien grade 2, and this was the case for renal stones only. No urinary tract infections were observed. The new Soltive TFL appears to be a remarkably promising tool in the therapeutic approach of urolithiasis. Lithotripsy was achieved up to the level of extremely small stone fragments with improved efficiency while also optimizing the operative time.

Relationship between TP53 and interleukin-6 gene variants and the risk of types 1 and 2 diabetes mellitus development in the Kermanshah province.

Abstract: Diabetes mellitus (DM) is a metabolic disorder that results from insufficient secretion or insulin resistance, or both. Insulin secretion deficiency leads to chronic hyperglycemia along with impaired metabolism of proteins, lipids, and carbohydrates. This study aimed to investigate the TP53 gene SNP (single nucleotide polymorphism) rs1042522 genotype and the interleukin-6 (IL-6) gene SNP rs1800795 genotype in DM and control groups. This study was performed on 70 patients with type 1 DM, 100 patients with type 2 DM without related complications, 66 control subjects for type 1 DM, and 95 control subjects for type 2 DM. The control groups were matched regarding age and gender and did not have a familial relationship with the patient groups. All the subjects were residents of Kermanshah, located in the western part of Iran. Polymorphisms of TP53 and IL-6 genes were determined by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Lipid profile, fasting blood glucose, and HbA1c were measured using the ELISA and immunoturbidometric methods. The frequency of genotypes (CC, CG, GG) of the TP53 gene codon 72 in type 1 DM and its control group were significantly different (P= 0.013). Likewise, the frequency of genotypes (CC, CG, GG) of the TP53 gene codon 72 was significantly different between type 2 DM and control groups (P <0.001). The frequency of genotypes (GG, GC, CC) of G174C polymorphisms in the IL-6 gene was different between type 1 DM and control group as well as between type 2 DM and its control group, but it was not statistically significant. SNP rs1042522 genotypes in the dominant form (CG + GG vs. CC) (OR= 3.880; P < 0.001) and alleles G vs. C alleles (OR= 0.384; P < 0.001) increased the risk of type 2 DM significantly. There was no significant difference between type 1 and type 2 DM groups and respected control groups regarding the frequency of the IL-6 gene SNP rs1800795 alleles. The G allele of SNP rs1042522 encoding the TP53 gene increases the risk of developing DM in the population of the Kermanshah province, Iran.

25-OH Vitamin D blood serum linkage with VDR gene polymorphism (rs2228570) in thyroid pathology patients in the West-Ukrainian population.

Abstract: Vitamin D is known to alter immune regulation. It binds to the vitamin D receptors (VDR) expressed on T lymphocytes and macrophages. In individuals with Hashimoto's thyroiditis, serum vitamin D levels were found to be lower compared to healthy controls. The study's objective was to investigate the association between VDR gene polymorphism (rs2228570) with blood serum levels of 25-OH vitamin D in patients with thyroid pathology from western Ukraine. The study involved a total of 153 patients with various forms of thyroid pathology. 25-OH vitamin D levels in the serum of the patients and healthy individuals were quantified with ELISA using the 25-OH vitamin D Total (Vit D-Direct) Test System ELISA Kit (Monobind Inc.®, United States, Product Code: 9425-300) on the EIA Reader Sirio S (Seac, Italy). Genotyping of the VDR (rs2228570) gene polymorphism was performed using TaqMan probes and TaqMan Genotyping Master Mix (4371355) on CFX96™Real-Time PCR Detection System (Bio-Rad Laboratories, Inc., USA). Polymerase chain reaction (PCR) for TaqMan genotyping was carried out according to the kit instructions (Applied Biosystems, USA). Our research identified that that genotype variants of VDR rs2228570 are not risk factors for reduced serum 25-OH vitamin D or vitamin D deficiency in patients with various forms of thyroid pathology patients in the West-Ukrainian population. Vitamin D levels were significantly lower in the carriers of AA and AG genotypes with hypothyroidism caused by autoimmune thyroiditis. In AA genotype carriers with postoperative hypothyroidism, 25-OH vitamin D levels were significantly lower compared to AA genotype carriers with autoimmune thyroiditis.

Bioresonance therapy may treat depression

Abstract: The aim of the study was to evaluate if bioresonance therapy can offer quantifiable results in patients with recurrent major depressive disorder and with mild, moderate, or severe depressive episodes by decreasing the level of depression due to the application of bioresonance therapy as independently or complementary treatment. The study included 140 patients suffering from depression, divided into three groups. The first group (40 patients) received solely bioresonance therapy, the second group (40 patients) received pharmacological treatment with antidepressants combined with bioresonance therapy, and the third group (60 patients) received solely pharmacological treatment with antidepressants. The assessment of depression was made using the Hamilton Depression Rating Scale, with 17 items, at the beginning of the bioresonance treatment and the end of the five weeks of treatment, aiming to decrease the level of depression. The study identified the existence of a statistically significant difference for the treatment methods applied to the analyzed groups (p=0.0001), and we found that the therapy accelerates the healing process in patients with depressive disorders. Improvement was observed for the analyzed groups, with a decrease of the mean values between the initial and final phase of the level of depression, of delta for Hamilton score of 3.1, 3.8 and 2.3, respectively. We concluded that the bioresonance therapy could be useful in the treatment of recurrent major depressive disorder with moderate depressive episodes independently or as a complementary therapy to antidepressants.

The role of the intestinal ultrasound in Crohn's disease diagnosis and monitoring.

Abstract: Crohn's disease is characterized by persistent or recurrent chronic inflammation that may affect any segment of the gastrointestinal tract. It has an oscillating evolution, with periods of activity alternating with periods of remission. Crohn's disease has a significant impact on the economic status due to its increasing prevalence, often affecting young people. Suitable management for these patients involves frequent evaluations. Even though colonoscopy is the gold standard for the assessment of severity and mucosal healing, it is an invasive maneuver, not easily accepted by patients, and it does not have good repeatability. Intestinal ultrasound has the advantage of being non-irradiating, non-invasive, well-tolerated, cheap, and easy to repeat. Ultrasound parameters such as bowel wall thickness, intestinal wall architecture, intramural vascularisation, proliferation of mesenteric fatty conjunctive tissue, and intraperitoneal fluid can provide good information regarding the severity of the disease, the differentiation between remission and relapse, and its complications. Some of the latest studies show good correlations between ultrasound parameters and inflammation markers (C-reactive protein, fecal calprotectin) and clinical severity scores of Crohn's disease. Consequently, the importance of intestinal ultrasound has increased lately, and recent studies support its use to evaluate the severity of inflammation, differentiate between active disease and relapse, monitor therapy response and guide treatment, evaluate prognosis, and diagnose complications.

Knowledge, attitude and practice towards COVID-19 among individuals with associated comorbidities.

Abstract: The recent outbreak of coronavirus disease 2019 (COVID-19) is the worst global crisis after World War II. Since the vaccine trials are still ongoing, the national lockdowns have been the most effective way to contain its spread. The pandemic has been extremely stressful and full of anxiety for those with comorbidities as they are the most vulnerable to the COVID-19 infections. Various efforts to assess and enhance the knowledge, attitudes, and practice, especially the high-risk groups, are critical to managing the COVID-19 pandemic successfully. A cross-sectional online survey was carried out using a self-designed questionnaire. A total of 383 participants who were 30 years or older, with at least one comorbidity, were included in the study. The mean age of the participants was 50.63±11.83 years. The most common comorbidities among the included participants were hypertension, followed by diabetes mellitus and thyroid disorders (48.5%, 44.7% and 23.3%, respectively). Our study also showed the education (p=0.004) and occupation (p=0.04) had a significant association with the attitude and practices towards the COVID-19 pandemic. In conclusion, our study showed that a high level of knowledge, attitude, and practices are the backbone to combat a global crisis like COVID-19.

How and why do we screen for colorectal cancer

Abstract: After almost 50 years of data analysis, screening for colorectal cancer has proven to be an effective tool in reducing colorectal cancer mortality. However, implementing the optimal strategy represents a challenge for many healthcare facilities around the world. There is much discussion regarding how screening should be done, the optimal tools that should be used, and the proper timing for screening procedures. Another essential step is to maintain the adherence of patients to screening programs. Also, the recommendation for lowering the age to initiate screening is in progress, as there is an increase in colorectal incidence in people born after 1970.

Perception of telemedicine among medical practitioners in Malaysia during COVID-19.

Abstract: The novel Coronavirus Disease 2019 (COVID-19) has brought unprecedented changes in the way conventional health care is delivered. This study examined if clinicians' perceptions regarding telemedicine and its barriers to implementation in Malaysia have changed during this pandemic. A cross-sectional survey was conducted among Malaysian medical doctors of various specialties in four urban healthcare facilities between June 2020 and July 2020. A total of 146 (41.7%) out of 350 responses were obtained. 62% of doctors reported a reduction greater than 50% in outpatient visits during the COVID-19 pandemic. The majority of doctors either found telemedicine useful in situations similar to COVID-19 (34.2%) or that it is essential to their daily practice (42.5%). However, only 22% reported using telemedicine for consultation during the COVID-19 pandemic. 74% of doctors felt that telemedicine would only benefit up to 30% of their patient population. Significantly more female doctors (80%) felt that telemedicine would benefit their patients compared to male doctors (45.8%) (P=0.03). Physicians (51.3%) were more inclined to adopt telemedicine in comparison to surgeons (32.4%) (P=0.03). The majority cited medico-legal issues and consent (80.6%), billing and charges (66.7%) and insurance reimbursement (62.5%), technical difficulties (62.5%) as their barrier to the adoption of telemedicine. Female doctors and physicians were more willing to adopt telemedicine when compared to male doctors and surgeons. Although the COVID-19 pandemic appeared to improve the perception, significant barriers should be resolved before many can incorporate it into their practice.

Acute esophageal necrosis following kidney transplantation.

Abstract: We are reporting a case of spontaneous acute esophageal necrosis "black esophagus" of unclear etiology in a kidney transplant recipient. A patient with end-stage renal disease due to IgA nephropathy received a deceased-donor kidney transplant. The surgical procedure was uneventful, without hemodynamic instability. He was started on alemtuzumab for immunosuppression induction followed by maintenance immunosuppression with intravenous methylprednisolone for 3 days, then oral prednisone, mycophenolate mofetil and tacrolimus (a target level between 8 and 10ng/ml) daily. On postoperative day (POD) 3, the patient started to develop significant gastro-intestinal symptoms: epigastric pain, dysphagia, odynophagia, eructation, pyrosis, nausea, and regurgitation of food contents. He was diagnosed with esophageal necrosis by upper endoscopy on postoperative day 4. We describe a successful treatment with supportive therapy and complete recovery despite receiving immunosuppressive therapy. To our knowledge, this case is one of the few reported cases of esophageal necrosis in kidney transplant recipients and the first case that was not associated with clinical risk factors.

The "no-touch" technique in the flexible ureteroscopic approach of renal stones.

Abstract: Large meta-analyses demonstrated that ureteral access sheaths (UAS) have specific complications during and after flexible ureteroscopy (fURS). The present study focused on the technical aspects, advantages, drawbacks, and limitations of the latest "no-touch" technique (NTT) in the flexible ureteroscopic therapeutic approach of renal stones. A total of 288 patients with a single pyelocaliceal stone (largest diameter between 11 and 29 mm) underwent fURS: 144 using the 12/14 Fr UAS (group 1) and 144 without UAS (group 2). For NTT, we used four types of ureteroscopes: Olympus URF-V2 (8.5 Fr) - 33 cases, Storz Flex X2 (8.4 Fr) - 60 cases, single-use PUSEN PU 3022 (9.5 Fr) - 37 cases, and single-use PUSEN - PU 3033A (7.5 Fr) - 14 cases. For group 1, we used the Olympus URF-V2 ureteroscope in 44 cases, the Storz Flex X2 in 58 cases, and the single-use PUSEN PU 3022 in 42 cases. We compared the operative time, hospitalization periods, and complications. Successful access sheath insertion was noted in 83.3% of cases from group 1, and successful ureteroscope insertion was noted in 90.9% of cases from group 2. The average operative time was slightly higher in group 1 vs. group 2 (47 vs. 39 min). Stone-free rates (SFRs) were overall lower in group 2 (76.3% vs. 86.8%) at 1 month. At 3 months, we did not find a significant difference between these two groups. Superficial mucosal ureteral wall lesions were found in 38.8% of patients from group 1 and 4.1% from group 2. Hospitalization periods were longer in group 1 vs. group 2 (21 vs. 29 hours, respectively). The single-use 7.5 Fr ureteroscope should receive a special mention: the insertion was simple, we did not encounter any mucosal ureteral wall lesions, and all patients were discharged on the same day. Despite the clear advantages of routine UAS usage, there are many adverse events for the patient. Larger diameter sheaths involve a greater risk of ureteral wall injury. NTT seems to improve peri- and postoperative safety while preserving therapeutic efficiency. The new 7.5 Fr ureteroscopes appear to optimize surgical efficiency and diminish complications in the flexible ureteroscopic treatment of renal stones.

Analysis of long-term results of pathogenetic treatment of Helicobacter pylori-associated gastroduodenopathies induced by nonsteroidal anti-inflammatory drugs in patients with osteoarthritis.

Abstract: The study of the pathogenetic treatment and prevention of Helicobacter pylori (Hp)-associated gastroduodenopathies (GDP) induced by nonsteroidal anti-inflammatory drugs (NSAIDs) in patients with osteoarthritis (OA) is one of the most serious problems in modern clinical medicine. Sixty patients with OA and concomitant Hp-associated GDP induced by NSAIDs were examined. The levels of epidermal growth factor (EDF), sAPO-1/Fas and tumor necrosis factor-α (TNF-α) were determined. Group I included 30 patients who received triple anti-Helicobacter (AHT) therapy, and group II included 30 patients who received rebamipide. Long-term effects were assessed 6 months and 1 year after treatment. All subjects showed a significant increase in TNF-α (4.7 times), EDF (2.2 times) and a decrease in sAPO-1/Fas (3.6 times) levels compared to healthy individuals. After 1 month of treatment, a significantly more significant decrease in TNF-α and an increase in sAPO-1/Fas and EDF was found in group II. In the long-term treatment, a further decrease in TNF-α and an increase in the content of sAPO-1/Fas levels were observed in all groups. However, these changes were significantly more significant in group I compared to group I. The long-term follow-up showed a declining trend of EDF in all groups. The data obtained indicate the effectiveness of rebamipide in the complex pathogenetic treatment and prevention of Hp-associated GDP induced by NSAIDs in patients with OA.

Chlorhexidine, clotrimazole, metronidazole and combination therapy in the treatment of vaginal infections.

Abstract: This was a clinical trial study that aimed to investigate the efficacy of vaginal chlorhexidine gel in the treatment of vulvovaginal candidiasis, bacterial vaginosis, and nonspecific vaginitis. The study population included patients who complained of vaginal discharge and presented to our University Gynecology Clinic. The data were analyzed using the Statistical Package for the Social Sciences (SPSS) software. The student t-test and Mann-Whitney U test were used to analyze the quantitative and ordinal data, respectively. In order to analyze the qualitative data, the Chi-square or Fischer's exact tests were used. The mean satisfaction score in the vulvovaginal candidiasis patients who received chlorhexiine vaginal gel was 9.06 and 8.29 in the patients who received clotrimazole vaginal cream. The Mann-Whitney test did not show a statistically significant difference between mean scores of VAS in these two groups with vulvovaginal candidiasis (P=0.027). Among the patients with bacterial vaginosis, the mean satisfaction score was 8.91 in the chlorhexidine vaginal gel group and 8.72 in the metronidazole tablet group (P=0.607). In the nonspecific vaginitis group, the mean satisfaction score was 8.83 in the chlorhexidine vaginal gel group and 9.17 in the combination group (metronidazole + clotrimazole vaginal cream)(P=0.401). The highest mean visual analog scale score (VAS) score was documented in the combination therapy group. We found that chlorhexidine vaginal gel is a more effective method for the treatment and improvement of vaginal infections. The benefits of chlorhexidine gel have a positive therapeutic effect as a single drug in nonspecific vaginitis, rather than simultaneous administration of two agents.

Indicators of antioxidant protection of blood in necrotizing ulcerative gingivitis in experimental animals

Abstract: This article highlights the results of a study of blood parameters in animals with simulated necrotizing ulcerative gingivitis and compares them, under the same conditions, with animals that received local treatment with a developed complex of antioxidant drugs. Following the work tasks, the nature of changes in the state of the antioxidant - prooxidant system and their influence on quantitative and functional indicators of markers of inflammatory intensity was analyzed and investigated during the pathological process in the background and without treatment with a developed complex. This work shows the changes of malonic dialdehyde concentration as an indicator of lipid peroxidation intensity in experimental animals, the level of catalase activity in the blood of animals, and antioxidant-prooxidant balance in the dynamics of necrotizing ulcerative gingivitis.

Orthodontic treatment in times of Covid-19.

Abstract: During the first two months of the Coronavirus Disease 2019 (Covid-19) pandemic, Romania was in lockdown, and all dental practices were closed, so orthodontic patients had to postpone their check-ups for at least eight weeks. This led not only to a delayed end of treatment but also to accidents and complications. The present study tried to evaluate the orthodontic situation both from the patient's and orthodontist's point of view, so the patients were given a few questions to answer, and the orthodontist analyzed each treatment before and after the two-month lockdown and decided if it was mildly or severely affected by the absence of check-ups. The study group consisted of 105 patients evaluated by three orthodontists in the same private practice. Patients that have gotten worse after the lockdown or who had problems were included in the study. Also, all the patients were given a 7-question form in order to find out their opinion. After two months without check-ups, our orthodontists found that 9.52% got worse because of the lack of intermaxillary elastics, broken brackets, broken removable orthodontic appliances, and others. Most of the patients believe that their treatment was delayed by the Covid-19 pandemic, but none of the patients felt unsafe when visiting the clinic. The Covid-19 pandemic had severe effects on orthodontic treatments. Orthodontists noticed a delay for about one-third of their patients. However, from the patient's point of view, half believe that their treatment was negatively affected by the Covid-19 pandemic in different degrees.

Evaluation of the sealer/gutta-percha ratio on sets of root section surfaces of some extracted teeth sealed using the cold lateral condensation technique.

Abstract: Canal filling must be well adapted to the walls of the root canal to prevent bacterial infiltration. Endodontic seals play an essential role in ensuring tightness, without which the canal filling would suffer infiltrations. This study aimed to evaluate the areas occupied by the two components of the canal filling, as well as the sealer/gutta-percha ratio in the root canals of the maxillary central incisors after their filling using the cold lateral condensation technique with gutta-percha. Thirty extracted upper central incisors were rotatably prepared with ProTaper Universal up to F3 and sealed using the cold lateral condensation technique with gutta-percha. After setting the sealer, the roots of the teeth were sectioned perpendicularly to 1 (L1), 3 (L3), 6 (L6), and 8 (L8) mm from the apex. The surface of the sections was analyzed with a Leica EZ4D stereomicroscope and photographed at two magnification orders: 10x and 25x. The areas corresponding to the gutta-percha, sealer, gaps, and root canal were expressed in pixels using the ImageJ software, version 1.50i. The difference in the representation of sealer areas, gutta-percha and voids was statistically significantly different for all four sections analyzed. The best adaptation of the canal obturation was observed in L1 and L3. The gutta-percha area was statistically significantly higher than that of the sealer for the L1, L3, and L6 levels, while the sealer/gutta-percha ratio recorded the lowest value at the L3 level (0, 30) and the highest at its L8 (0.70) level, without registering statistically significant differences regarding the area at the four analyzed levels. The voids were mostly absent or recorded a minimal percentage area (<1%). Cold lateral condensation of gutta-percha has led to a good adaptation of gutta-percha to the root canal wall, with a small amount of sealer, especially to the sections made at 3 mm from the apex. Given the limitations of this study, we noted that the voids were few - observed in the 6 and 8 mm sections - and were negligible in many cases.
