Hereditary pancreatitis: Report of a family from Turkey

Chronic pancreatitis is a rare disease in children and is usually secondary to underlying diseases such as hereditary pancreatitis, cystic fibrosis, hyperlipidemia, prolonged malnutrition, gallstones or anomalies of the biliary-pancreatic duct system. Hereditary pancreatitis is a common cause of chronic pancreatitis in children but is often unrecognized until months or years later. We report here a family with hereditary pancreatitis in which four members are affected.     

The actual incidence of bladder perforation following transurethral bladder surgery

PURPOSE: In this prospective study we evaluated the incidence of bladder perforation after transurethral bladder tumor resection. MATERIALS AND METHODS: A total of 36 patients (33 male, 3 female, mean age +/- SD 65.6 +/- 11.43 [range 26 to 81]) with a solid mass in the bladder (mean 20.3 +/- 8.7 mm, range 5 to 40) were included in the study. Transurethral resections were performed with a 24Fr resectoscope. After the procedure an 18Fr Foley catheter was inserted into the bladder and 400 ml of 1/4 saline diluted contrast solution was instilled under gravity from 60 cm above the bladder. Complete filling and post-drainage radiographs were taken and examined for any evidence of extravasation. Regular evaluations with cystoscopy and ultrasound/computerized tomography were done to detect possible tumor recurrence and perivesical seeding. RESULTS: Histopathological examination of the tumors showed transitional cell carcinoma in 35 patients and chronic eosinophilic cystitis in 1. Review of the cystograms revealed various degrees of extraperitoneal contrast extravasation around the resected area in 21 patients (58.3%). The only statistically significant difference between patients with and without extravasation was in tumor size (logistic stepwise regression p = 0.030,) among factors tested including patient age and localization, number of foci, tumor grade and stage. No apparent clinical problems requiring medical or surgical intervention other than urethral catheterization developed and no evidence of extravesical tumor seeding as per ultrasound and/or computerized tomography was seen during a mean followup of 21.9 months (range 7 to 40). CONCLUSIONS: The extravasation of urine (asymptomatic perforation) after transurethral bladder tumor resection may occur much more frequently than believed or reported. It seems that this extravasation does not impose a significant risk of extravesical tumor seeding.     

Relationship between sleep complaints and proinflammatory cytokines in haemodialysis patients

BACKGROUND: Sleep complaints are common in end-stage renal disease. We aimed to investigate the relationship between sleep-related complaints and inflammatory cytokines in haemodialysis (HD) patients, and also the effects of HD on sleep patterns and cytokine levels. METHODS: Predialysis serum interleukin-1beta (IL-1beta), interleukin-6 (IL-6) and tumour necrosis factor-alpha (TNF-alpha) levels in nine patients with sleep complaints were compared with those of nine patients without sleep complaints and nine healthy controls. Patients with sleep complaints underwent polysomnography the night after HD and the following night. RESULTS: Patients with sleep complaints had significantly higher predialysis IL-1beta levels compared with those without and healthy controls (P=0.004 and P=0.000, respectively). They also had higher predialysis IL-6 and TNF-alpha levels than those without sleep complaints; however, the difference was not significant. Patients without sleep complaints had higher mean IL-6 and TNF-alpha and similar mean IL-1beta levels compared with healthy controls (P=0.001, P=0.024, P=0.26, respectively). Obstructive sleep apnoea syndrome (OSAS) was found in six out of nine (66%) patients with sleep complaints. Sleep architecture and cytokine levels did not differ between the two nights. The mean serum IL-1beta, IL-6 and TNF-alpha levels did not differ in the pre- and post-polysomnographic samples. There was no correlation between IL-1beta, IL-6 or TNF-alpha levels and the apnoea-hypopnoea index. CONCLUSIONS: Proinflammatory cytokines, IL-1beta in particular, might be associated with sleep complaints in HD patients. OSAS is not uncommon in HD patients with sleep-related complaints and sleep architecture does not appear to be effected by the HD procedure itself.     

Psoas abscess twenty-one years after ipsilateral nephrectomy

We report an unusual case of psoas abscess,which developed twenty-one years afteripsilateral nephrectomy and was caused byinfrequent pathogen, Proteus mirabilis.It was diagnosed by computed tomography andwas drained percutaneously with a nephrostomytube guided by ultrasonography.     

The relation of prostate biopsy results and ratio of free to total PSA in patients with a total PSA between 4–20 ng/mL

Objective: In this study our aim was to investigate the efficacy of free tototal PSA ratio in discrimination of benign prostate hyperplasia andprostate cancer.Materials and methods: A total of 194 patients, 52 to 82 years old (mean66.06 ± 0.47 years) with PSA levels between 4 to 20 ng/mL wereincluded into this study. Each patient underwent sextant prostate biopsyunder transrectal ultrasound guidance. The patients were divided into twogroups as PSA 4–10 and 10–20 ng/mL. Patients with benign and malignresults were compared with respect to age, total PSA level, free PSA leveland free/total (f/t) PSA ratio.Results: Biopsies revealed prostate cancer in 16 of 130 patients (12.3%)with serum PSA 4–10 ng/mL and in 10 of 64 patients (15.6%) with serumPSA 10–20 ng/ml. In both PSA groups free PSA and f/t PSA levels werestatistically significant, where total PSA levels were not. In patients with4–20 ng/mL total PSA levels and a cut off level of < 0.18 for f/t PSA, thesensitivity, specificity and positive predictive value for prostate cancerwere 88.5%, 53.6% and 20.4% respectively.Conclusion: Higher levels of PSA suggest prostate cancer, but stilladditional parameters are needed for patients with PSA 4–20 ng/mL, suchas free PSA and f/t PSA. Although a cut off level of < 0.18 for f/t PSA seemsto be the most accurate one to discriminate benign and malign diseasesfurther studies on larger groups of patients are needed.     

By reducing TGF beta 1, octreotide lessens the peritoneal derangements induced by a high glucose solution.

BACKGROUND: Chronic peritoneal dialysis may eventually result in peritoneal fibrosis, which progressively reduces dialytic efficacy. Although the pathogenesis has not been elucidated, it has been proposed that transforming growth factor beta-1 (TGF beta 1) plays a central role in the onset of peritoneal fibrosis. METHODS: Rats were divided into three groups and given saline, hypertonic peritoneal dialysis solution alone, a hypertonic peritoneal dialysis solution plus octreotide intraperitoneally. After four weeks, a one-hour peritoneal equilibration test was done. Dialysate-to-plasma urea ratio, glucose reabsorption, ultrafiltration volume and levels of dialysate protein, TGF beta 1 and cancer antigen 125 (CA 125) were determined. The peritoneal membrane was examined histologically by light microscopy. RESULTS: Compared to the saline group, peritoneal function tests (ultrafiltration volume 6 (5-7) vs 0.0 ml, dialysate-to-plasma urea ratio 0.51 vs 0.76, glucose reabsorption 0.54 vs 0.40 and morphology (thickness 4.5 vs 75.5 microns) were dramatically deranged in hypertonic peritoneal dialysis solution-treated rats, which also had a higher level of TGF beta 1 and undetectable CA 125. In contrast, in hypertonic peritoneal dialysis solution plus octreotide rats' peritoneal function was protected (ultrafiltration volume 3 mL, dialysate-to-plasma urea 0.60, glucose reabsorption 0.51) but peritoneal thickening (37.7 microns) was not so markedly reduced although the production of TGF beta 1 was significantly inhibited. CONCLUSION: These data show that by inhibiting the production of TGF beta 1, octreotide can preserve peritoneal function and remodeling of the mesothelial cell. Although the production of TGF beta 1 was significantly inhibited, peritoneal thickening cannot be completely prevented.     

Incidence of stress urinary incontinence among women in Turkey

The aim of this study was to determine the incidence of stress urinary incontinence among women at the age of 15 and above who applied to the primary health care centers in Ankara, Turkey. We applied the urinary stress incontinence questionnaire to 2,601 women at the age of 15 or above who consulted to the “mother–child health care and family planning centers” in January 2002. To evaluate the urinary incontinence status with respect to age groups and other risk factors, chi-square test was used. Stress incontinence prevalence was 16.1% in our population. Age was a statistically significant risk factor affecting the incidence of stress incontinence. As the number of gravida increases, the frequency of stress incontinence increases (p<0.05). Presence of a systemic disease was also an important risk factor (p<0.05). Alcohol use and smoking were not found to affect the incidence of urinary stress incontinence (p>0.05). As urinary incontinence greatly influences life quality and social and psychological status of the person, and also creates economic burden, predisposing factors of stress incontinence should be well defined and measures should be taken to encourage women experiencing this problem to visit a doctor and to get an efficient treatment.
