RESUMEN
Granular cell tumors (GCT) are uncommon tumors that originate in any part of the body. They have been mainly observed in the skin and soft tissue of the head and neck, and are mostly benign tumors. Urinary bladder GCT are extremely rare tumors. The diagnosis of urinary bladder GCT needs high clinical suspicion by the urologist and the pathologist. We herein report a case of rare granular cell tumor of the urinary bladder in a young woman.
RESUMEN
BACKGROUND: In the developing world, transplantation is the most common long-term treatment for patients with end-stage renal disease, but rates and causes of graft failure are uncertain. METHODS: This was a retrospective outcomes study of renal transplant patients seen in Iraqi Kurdistan nephrology clinics in the year 2019. In 2019, 871 renal transplant patients were registered and outcomes followed through 12/31/2020. Indicated renal biopsies were obtained on 431 patients at 1 day to 18 years post-transplantation. Outcomes were compared with United States Renal Data System (USRDS) living donor reports. RESULTS: All donors were living. The recipient age was 38.5 ± 13.3 years, 98.2% were < 65 years old, 3.7% had previous transplants, and 2.8% had pretransplant donor-specific antibodies (DSA). Gehan-Breslow estimated failure rates for all-cause, return to HD, and death with functional graft were 6.0, 4.2, and 1.9% at 1 year and 18.1, 13.7, and 5.1% at 5 years post-engraftment (USRDS 2000; 1 year: 7.0, 5.0, 2.6%; 5 year: 22.3, 15.2, 10.6%. USRDS 2010; 1 year: 3.7, 2.4, 1.4%; 5 year: 15.3, 9.6, 7.3%). The median graft survival was 15 years. Acute tubular injury (ATI), infarction, and acute T cell-mediated rejection accounted for 22.2% of graft loss, with > 75% of these failures taking place in the first year. Most graft failures occurred late, at a median post-transplant time of 1125 (interquartile range, 365-2555) days, and consisted of interstitial fibrosis and tubular atrophy (IF/TA) (23.8%), transplant glomerulopathy (13.7%), and acquired active antibody-mediated rejection (12.0%). The significant predictors of graft loss were C4d + biopsies (P < 0.01) and advanced IF/TA (P < 0.001). CONCLUSIONS: Kurdistan transplant patients had graft failure rates similar to living donors reported by the USRDS for the year 2000 but higher than reported for 2010. Compared to USRDS 2010, Kurdistan patients had a moderate excess of HD failures at one and 5 years post-engraftment. Nevertheless, prolonged survival is the norm, with chronic disorders and acquired DSA being the leading causes of graft loss.

INTRODUCTION: Mullerianosis is a sporadic condition of the urinary bladder. The study aims to present a case of mullerianosis with a brief literature review. CASE PRESENTATION: A 52-year-old lady presented with hematuria for one-year duration. A general urine examination showed microscopic hematuria. Abdominal and transvaginal ultrasonography revealed a soft tissue mass (13 * 10 mm) within the base of the urinary bladder. Cystoscopy showed 1.0 * 1.3 cm benign-looking mass bulging into the posterior bladder wall covered by a normal bladder mucosa. Transurethral resection was done. The histopathological examination was consistent with mullerianosis. DISCUSSION: Two hypotheses have been proposed; the first one (implantation theory) believing that at the time of pelvic surgery and caesarian delivery Mullerian tissues become implanted inside the bladder. The second theory (metaplastic theory) holds the probability of differentiation of Mullerian epithelium to endometrial, endocervical, and tubal components and proliferation in the bladder. CONCLUSION: mullerianosis is a very infrequent entity that mainly affects the urinary bladder and is mainly reported in females during the reproductive period, medical and surgical treatment are both regarded as the management options.
RESUMEN
BACKGROUND: The incidence of kidney diseases among bodybuilders is unknown. METHODS: Between January 2011 and December 2019, the Iraqi Kurdistan 15 to 39 year old male population averaged 1,100,000 with approximately 56,000 total participants and 25,000 regular participants (those training more than 1 year). Annual age specific incidence rates (ASIR) with (95% confidence intervals) per 100,000 bodybuilders were compared with the general age-matched male population. RESULTS: Fifteen male participants had kidney biopsies. Among regular participants, diagnoses were: focal segmental glomerulosclerosis (FSGS), 2; membranous glomerulonephritis (MGN), 2; post-infectious glomeruonephritis (PIGN), 1; tubulointerstitial nephritis (TIN), 1; and nephrocalcinosis, 2. Acute tubular necrosis (ATN) was diagnosed in 5 regular participants and 2 participants training less than 1 year. Among regular participants, anabolic steroid use was self-reported in 26% and veterinary grade vitamin D injections in 2.6%. ASIR for FSGS, MGN, PIGN, and TIN among regular participants was not statistically different than the general population. ASIR of FSGS adjusted for anabolic steroid use was 3.4 (- 1.3 to 8.1), a rate overlapping with FSGS in the general population at 2.0 (1.2 to 2.8). ATN presented as exertional muscle injury with myoglobinuria among new participants. Nevertheless, ASIR for ATN among total participants at 1.4 (0.4 to 2.4) was not significantly different than for the general population at 0.3 (0.1 to 0.5). Nephrocalcinosis was only diagnosed among bodybuilders at a 9-year cumulative rate of one per 314 vitamin D injectors. CONCLUSIONS: Kidney disease rates among bodybuilders were not significantly different than for the general population, except for nephrocalcinosis that was caused by injections of veterinary grade vitamin D compounds.
