Recurrent Urinary Tract Infections in Renal Transplant Recipients: Risk Factors and Outcomes in Low-resource Settings.

Recurrent urinary tract infections (UTIs) after kidney transplantation are a common problem adversely affecting graft outcomes. This retrospective study aimed to report the frequency and risk factors of recurrent UTI and their impact on graft and patient outcomes in kidney transplant recipients at the Sindh Institute of Urology and Transplantation, Karachi, Pakistan, in January-December 2015. Five-year graft and patient survival rates were compared among different groups using Kaplan-Meier analysis. Of the 251 recipients, 67 developed one episode of UTI. Of these 67, 29 had 76 episodes of recurrent UTI. Out of the 76 episodes of recurrent UTI, Escherichia coli was the most common pathogen in 32 cases. Organisms causing recurrent UTI showed resistance to carbapenem in 19 cases versus 2 in the non-recurrent UTI group (P = 0.006). The estimated glomerular filtration rate at 1 year was 57.8 ± 16.23 mL/min/1.73 m2 in the recurrent UTI group vs. 61.9 ± 15.7 mL/min/1.73 m2 in the non-recurrent UTI group (P = 0.001). Graft survival in the recurrent UTI group at 5 years was significantly lower (76%) than in the non-recurrent UTI (95%) and no UTI groups (93%) (log-rank P = 0.006), with no significant effect on patient survival in these groups (P = 0.429). The presence of double-J stent (P = 0.036) and cytomegalovirus infections (P = 0.013) independently predicted recurrent UTI. Recurrent UTIs are common in low-resource settings and adversely affect graft outcomes. Appropriate prophylaxis and treatment are important to reduce recurrent UTI to improve graft outcomes.

E-learning in postgraduate urology training: A Covid-19 pandemic experience.

Since the declaration of the Covid-19 pandemic in March 2020, several teaching institutions started the process of adjusting to the new challenge. Medical education could not be imparted the way it used to be and some new methods had to be taken to adapt to the pandemic. At our institute, an online e-teaching approach was adopted to ensure the continuation of post-graduate medical training. Each week two lectures were recorded and uploaded on the YouTube Channel and shared with the students. This was followed by an MCQ based test using Google forms. Ten lectures were delivered in five weeks to 55 participants. The majority of residents agreed that this activity increased their knowledge of the subject and opted to continue it in future. With the help of short online lectures (< 30 minutes) and online tests (5 MCQs), the learning experience of residents can be enhanced. In future, more online resources can be used to incorporate this method of teaching.

Chondrosarcoma of right big toe with metastases to left orbital and left infra temporal region.

To report a case of chondrosarcoma of right big toe with left orbital and left infra temporal metastases. Chondrosarcoma is the second most frequent primary malignant tumour of the bone. A 56 year old man had history of trauma on his right big toe, which was amputated and the biopsy in 2011 at Sindh Institute of Urology and Transplantation (SIUT) revealed chondrosarcoma with clear margins. Eventually the patient was presented with swelling of the left eye, pain and gradual loss of vision of that eye. Later a CT scan of his chest, brain and orbit showed pulmonary and pleural based nodule, with mediastinal and hilar lymphadenopathy representing metastatic deposit in left orbit, extending to left infra temporal region. A treatment of palliative chemotherapy was started with doxorubicin and ifosfamide, after which he was referred for radiotherapy. At that time he had loss of vision, pain and exopthalamus, and palliative radiotherapy was delivered to the left orbit with the prescribed dose of30 Gy/300cGy×10 fraction. Thereafter his case will be followed up at the oncology OPD after a 03 month interval.

Range for normal body temperature in hemodialysis patients and its comparison with that of healthy individuals.

BACKGROUND/AIMS: Patients with chronic kidney disease undergoing hemodialysis have an altered homeostasis leading to altered body temperatures. We aimed to determine the range for normal body temperature in hemodialysis patients and compared it to healthy individuals. Also, we determined how much axillary temperatures differed from oral temperatures in both groups and whether axillary temperature is affected by the presence of an arteriovenous fistula (AVF) in hemodialysis patients. METHODS: Oral and axillary (left & right) temperatures were recorded using an ordinary mercury-in-glass thermometer in 400 subjects (200 hemodialysis patients, 200 healthy individuals) at the Sindh Institute of Urology and Transplantation from mid-May to mid-June 2006. Comparisons were made between the temperatures of both groups. RESULTS: Mean oral temperature in hemodialysis patients was higher than in healthy individuals [98.7 degrees F (37 degrees C) vs. 98.4 degrees F (36.8 degrees C); p < 0.001], as was the mean average axillary temperature [97.7 degrees F (36.5 degrees C) vs. 97.5 degrees F (36.3 degrees C); p = 0.02] and mean left axillary temperature [97.9 degrees F (36.6 degrees C) vs. 97.6 degrees F (36.4 degrees C); p < 0.001]. The fistula arm had higher axillary temperature in 77 (44%) hemodialysis patients. The difference between oral and axillary temperatures varied widely, making it impossible to obtain an accurate correction factor in both groups. CONCLUSION: Hemodialysis patients have higher normal body temperatures than healthy individuals. Axillary temperatures require cautious interpretation. In hemodialysis patients, the non-fistula arm should be preferred for recording axillary temperatures, as the presence of AVF may cause discrepancies in temperature measurements.
