Cardiac strain of confectionery worker in relation to heat exposure during regular work shift.

Abstract: Context: In India, a wide variety of occupations are performed in adverse indoor working environment. Work physiological studies in these jobs are scanty as compared to investigations done on more arduous outdoor occupations. Aims and Objectives: Physiological strain of workers engaged in sweet making activities was assessed in terms of cardiac strain indices in relation to heat stress. Setting and Design: 33 full-time workers from eastern India were compared for cardiac strain profile obtained during summer and winter during their regular work shift. A comparison was also done in between younger (n=12) and older (n=16) subjects. Materials and Methods : Working heart rate (WHR) was recorded continuously during work. The pulse deceleration index (PDI) was obtained from recovery heart rate (RHR). Net cardiac cost (NCC) and relative cardiac cost (RCC) were the main indices used to evaluate physical strain. Thermal stress assessed from wet bulb globe temperature (WBGT). Statistical Analysis: Students' t-test and Wilcoxon signed rank paired tests were used for comparing physiological responses. Values were considered significant when P < 0.05. Results: Work load was significantly higher in summer for all workers. RCC of younger workers in winter and summer ranged between 18% and 26%. This was significantly lower as compared to the RCC of older workers which was 27% in winter and 30% in summer. The physiological workload appeared to be moderate in nature. The WBGT index was above the recommended range in summer for both the groups. Older workers showed a no recovery pattern in terms of recovery pulse that indicated toward a cumulative stress which may be attributed to a combined effect of heat and work in summer and extra amount of work performed in winter season. Conclusion: The physical workload is aggravated with various ergonomic stressors present in the work place. An ergonomic intervention has been indicated as further scope of this study.

Pattern of neuropsychiatric illnesses in older age group population: an inpatient study report from Nepal.

Abstract: Background: Inpatient institution-based geropsychiatric study reports are rare in the world psychiatric literature. Aims: To study the pattern of neuropsychiatric illnesses seen in older age group population and to study how the advancing age influences the pattern of physical and neuropsychiatric illnesses in these geriatric people. Materials and Methods: This was a retrospective review of the charts of all patients of age 60 years and above, during a specified period of 3.5 years. The present study reports the findings of 138 patients (83 males and 55 females) admitted during the said period. For comparison purpose, 194 patients, in the age range of 50-59 years, who were admitted during the same period, were taken up specially to study the changing pattern of diagnosis, if any, as well as to study the significance of increased rate of physical illness in the geriatric study group. Results: Our geriatric inpatients (138) formed only 3.73% of the total patient population (3698) admitted during the said period, which is in sharp contrast to 23-44% geriatric inpatients, the range that has been usually reported in the western literature. Common clinical diagnoses amongst male geriatric patients were alcohol dependence with or without various complications (27.7%), followed by mood disorder-mania (18.1%), organic mental disorders (18.1%), psychosis (16.9%), and mood disorder-depression (14.5%). Common clinical diagnoses amongst geriatric females were mood disorder-depression (36.4%) and psychosis (25.5%). Comorbid physical illness was seen to be present at a very high percentage (61.4%) in geriatric male patient population than in female patients (40%). Alcohol dependence in male and depressive disorder in female stood out as distinctive illness in patients above 50 years of age (including both study and comparative groups). In sharp contrast to elderly comparison group's 14.9% cases of comorbid physical illness, geriatric study population had a staggering 52.9% cases of additional burden of physical illness diagnosis. Conclusions: Being elder by a decade poses a significant threat in developing an additional physical illness to an already existing psychiatric illness in the geriatric community. Though the prevalence of mental illness in the geriatric age group is similar in developed and developing countries, poor inpatient attendance of geriatric neuropsychiatric patients probably indicates a poor delivery of healthcare facilities to our senior citizens.

Acute Appendicitis in Pregnancy and the Developing World

Abstract: Background. Acute appendicitis is the commonest nonobstetric surgical emergency during pregnancy. The aim of the study was to compare perioperative outcomes of acute appendicitis in pregnant and nonpregnant patients. Methods. A retrospective review of medical records of 56 pregnant patients between 2011 and 2016 who were compared with 164 nonpregnant women of reproductive age who underwent open appendectomy between 2014 and 2016 for acute appendicitis. The patient’s demographics and perioperative data were analyzed. Results. The median age of pregnant and nonpregnant patients observed was 26 years (range 19–37) and 26 years (range 18–43). There were no significant differences between the groups in negative appendectomy (21.4 and 21.3%, ), perforated appendicitis (25 and 23.8%, ), postoperative complications (28.6 and 26.8%, ), and median length of hospital stay (5 and 4.5 days, ). There were 3.6% preterm labour, no maternal mortality, and no fetal loss. In multivariate analysis, WBC >18000/mm3 and long patient time to surgery were independent risk factors for appendicular perforation and postoperative complication ( ). Conclusion. Our results of appendectomy in pregnant patients are comparable with nonpregnant patients. Hence the same perioperative treatment protocol can be followed in pregnant and nonpregnant patients even in resource-poor setting.

Spectrophotometric analysis evaluating apical microleakage in retrograde filling using GIC, MTA and biodentine: an in-vitro study.

Abstract: The present study compares the apical microleakage of three different root-end filling materials in which the retrograde cavity is prepared by two different burs. Eighty extracted single rooted maxillary and mandibular premolars were taken. Root canal treatment was completed. Apical 3 mm of all the teeth were resected with diamond disk. The tooth were divided into four groups with two subgroups for each group containing 10 tooth (N = 10) as: Group IA (Negative Control and IB (Positive Control); Group IIA and IIB: Prepared with round carbide bur and round diamond bur respectively, filled with GIC; Group IIIA and IIIB: Prepared with round carbide bur and round diamond bur respectively, filled with MTA; Group IVA and IVB: Prepared with round carbide bur and round diamond bur, filled with Biodentine. After applying two coats of nail varnish leaving apical 3 mm (except for negative control group) all teeth were immersed in 2% methylene blue for 3 days and again in 65% nitric acid for next 3 days for extraction of dye. The obtained solution was then transferred to eppendorf tube and centrifuged in microcentrifuges at 14,000 revolution per minutes (RPM) for 5 min. Optical density or absorbance of the supernatant solution was measured with UV spectrophotometer at 550 nm. The absorbance of the supernatant solution after dye extraction is decreasing in the order of positive control> GIC > MTA > Biodentine> negative control group. The significant difference was observed between GIC and MTA (p = 0.0001) and GIC and Biodentine (p = 0.0001) with two different burs but statistically non-significant difference was observed between MTA and Biodentine with Carbide bur (p = 0.127) and Diamond bur (p = 0.496) respectively. Within the limitations of the present study, it can be concluded that Biodentine and MTA showed less microleakage as compared to GIC. There is no significant difference between mean microleakage of MTA and Biodentine. However, the mean OD of the Biodentine was least of all evaluated materials. Preparation of the root-end using round carbide bur as well as round diamond burs showed comparable microleakage for all three filling materials.

Machining of AISI D2 Tool Steel with Multiple Hole Electrodes by EDM Process

Abstract: In recent years, with the increasing of technology the demand for machining processes is increasing for the newly developed materials. The conventional machining processes are not adequate to meet the accuracy of the machining of these materials. The non-conventional machining processes of electrical discharge machining is one of the most efficient machining processes is being widely used to machining of high accuracy products of various industries. The optimum selection of process parameters is very important in machining processes as that of an electrical discharge machining as they determine surface quality and dimensional precision of the obtained parts, even though time consumption rate is higher for machining of large dimension features. In this work, D2 high carbon and chromium tool steel has been machined using electrical discharge machining with the multiple hole electrode technique. The D2 steel has several applications such as forming dies, extrusion dies and thread rolling. But the machining of this tool steel is very hard because of it shard alloyed elements of V, Cr and Mo which enhance its strength and wear properties. However, the machining is possible by using electrical discharge machining process and the present study implemented a new technique to reduce the machining time using a multiple hole copper electrode. In this technique, while machining with multiple holes electrode, fin like projections are obtained, which can be removed easily by chipping. Then the finishing is done by using solid electrode. The machining time is reduced to around 50% while using multiple hole electrode technique for electrical discharge machining.
