Sensorineural Hearing Loss and Its Relationship with Duration of Chelation Among Major β-Thalassemia Patients

Abstract: Introduction Thalassemia is a common genetic disorder worldwide, also occurring frequently in Karachi, Pakistan. Beta (β)-thalassemia major patients need repeated transfusions which cause iron overload. Patients are treated with chelating agents to reduce the high serum ferritin level and to decrease morbidity and mortality due to increased iron levels. This combined therapy also leads to some complications. One of them is the sensorineural hearing loss (SNHL). To date, no data is available in Pakistan regarding SNHL among major β-thalassemia patients on chelating therapy. Methods A cross-sectional study was performed in collaboration with the Thalassemia Center and Dr. Ruth Pfau at the Department of Ear, Nose, and Throat, Civil Hospital, Karachi, Pakistan. The variable to detect hearing was pure tone air and bone conduction thresholds at the frequencies of 250 - 4,000 Hz. Clinical data, such as chelating agent dose, duration, and hearing status, were recorded. Demographic characteristics, like age, gender, height, and weight, were noted. The hemoglobin and serum ferritin levels of the subjects were also included. Results Forty-five percent of cases of thalassemia were suffering from SNHL. In the right ear, the Pearson correlation of chelating agent dose (mg) with SNHL was mildly positive and statistically significant (r = 0.261, p < 0.001), (r = 0.337, p < 0.001), (r = 0.198, p = 0.005), and (r = 0.207, p = 0.003) at the frequencies of 250, 500, 1,000, and 2,000 Hz, respectively, and the Pearson correlation of chelating agent used (in months) with SNHL was mildly positive and statistically significant (r = 0.232, p = 0.001), and (r = 0.301, p < 0.001) at frequencies 250 to 500 Hz, respectively. In the left ear, the Pearson correlation of chelating agent dose (mg) with SNHL was mildly positive and statistically significant, (r = 0.191, p = 0.007), (r = 0.202, p = 0.004), (r = 0.297, p < 0.001), (r = 0.183, p = 0.010) and (r = 0.221, p = 0.002) at frequencies 250, 500, 1,000, 2,000, and 4,000 Hz, respectively, and Pearson correlation of chelating agent used (months) with SNHL was mildly positive and statistically significant only at the frequency of 2,000 Hz (r = 140, p = 0.049). Conclusion Chelation therapy and regular blood transfusions, apart from prolonging the life of thalassemic patients, also leads to some complications. With this survey, it was concluded that almost half of the patients had normal hearing, while the other half had sensorineural hearing loss after the use of deferasirox. It is inferred that the incidence of SNHL is not only dose-related but the duration of use of a chelating agent is also a contributing factor.

Comparison of Testosterone Levels in Patients With and Without Type 2 Diabetes.

Abstract: Introduction Hypogonadotropic hypogonadism is a common disorder associated with type 2 diabetes. Hypogonadotropic hypogonadism in type 2 diabetic patients requires further assessment to understand the etiology, and the possible consequences, complications, and treatment This study aims to highlight the testosterone level in type 2 diabetes mellitus (DM). Moreover, it further emphasizes the association of testosterone with the duration of DM. Materials and method This case-control survey was conducted from September 2020 to March 2021 in the outpatient department of internal medicine in a tertiary care hospital in Pakistan. The experiment group included 200 diabetic male participants aged between 30 and 69 years. In the control group, 200 participants without DM were enrolled in the study. The venous blood sample was collected via phlebotomy and sent to the laboratory to test for total testosterone level. Results The mean total testosterone level was significantly lower in diabetic patients compared to the non-diabetic patients (8.9 ± 5.1 mmol/L vs. 14.1 ± 7.2 mmol/L; p-value: <0.0001) and the prevalence of androgen deficiency was significantly higher in diabetic patients compared to non-diabetic patients (45.5% vs. 20.5%; p-value: <0.00001). For each age group, the mean total testosterone level was significantly higher in the diabetic group compared to the non-diabetic group. There was a significant decline in mean total testosterone level as the duration of diabetes increased (p-value: 0.01). Conclusion Strong interlink between type 2 DM and low testosterone level has once again highlighted the importance of a broader approach toward men presenting in the diabetic clinic and provided a huge ground for prescribing testosterone replacement therapy in hypogonadal men with DM.

Calculus anuria and its remedy.

Abstract: Background: Urinary lithiases have been a major urological problem. The objective was to determine the out come of treatment for patients with calculus anuria. Methods: A descriptive study was conducted at Department of Urology Chandka Medical College Hospital, Larkana from March 2007 to April 2009. All patients with a diagnosis of calculus anuria of all ages and either sex were included in the study. Detailed history, physical examination and examination of genitourinary tract was performed. Investigations included complete blood examination, blood urea, serum creatinine, ultrasonography of KUB area, and X-Ray KUB. Results: Among the 66 patients the cause of anuria was bilateral obstruction by the calculi in 46 cases, unilateral obstruction with small/absent/ nephrectomised contralateral kidney in 20 cases. In most of the cases, ureteric catheterisation was done to relieve the obstruction. Five deaths were observed, despite emergency urinary diversion and appropriate treatment. Conclusion: Calculus anuria is a urological emergency. Prompt and early intervention can save the life of patient and prevent to develop chronic renal failure. Keywords: Anuria, calculus, and management

Low dose, short-term, triple therapy for helicobacter pylori associated peptic ulcer.

Abstract: To confirm the efficacy and tolerability of a new, low-dose, short-term triple therapy, 31 endoscopically diagnosed cases of peptic ulcer who were helicobacter pylori positive by brush cytology and urease test were inducted into the study. These patients were given lansoprazole 30 mg once a day, clarithromycin 250 mg twice a day and tinidazole 500 mg twice a day for one week only. Endoscopy, urease test and methylene blue test for helicobacter pylori were repeated four weeks after stopping the therapy. Ulcer healed in all the patients while helicobacter was eradicated in 90.3% of patients.

Myelography in spinal disorders--experience of 1400 cases.

Abstract: Objective: To evaluate the diagnostic importance of myelography in spinal disorders, in correlation with clinical presentation of the patients. Methods: Patients selected for myelography had presented with history of various spinal disorders such as low backache, neurogenic claudication, paraparesis or paraplegia, quadriparesis or quadriplegia, trauma to spinal region and infective spondylitis. Patients excluded were those with history of allergies to iodinated contrast agents, seizures coagulopathy and pregnant women. Contrast agent was water soluble non ionic agent - lohexol. Spinal Needles used were of 20,22 and 25 gauge. X-Ray machine with tilltable table was used for myelography. Results: There were 1400 patients of whom 935 were males and 465 females with male to female ratio of 2.1. Age range was 8 to 65 years. Spinal disorders diagnosed on myelography were lumbar disc prolapse 866 (60%) cases, lumbar canal stenosis 113 (8%), thoracic disc protrusions 15 (1%), infective spondylitis 53 (4%) cases, spinal tumors 36 (2.5%), spinal dysraphism 28 (2%) and traumatic spine in 85 (6%) cases. Free flow of contrast agent with no block was found in 149 (10.64%) cases. These were subjected for MRI scan which revealed significant pathological lesion of surgical importance in 23 cases (1.64%) only. Conclusion: Myelography is the least expensive valuable diagnostic test in spinal disorders specially in lumbar disc prolapses and lumbar canal stenosis.
