Spontaneous bladder rupture due to chronic cystitis 20 years after cystolithotomy

Spontaneous bladder rupture is a very rare condition. The majority of the cases are due to long-term indwelling catheters, radiation, or acute infravesical obstruction. Spontaneous rupture of the bladder due to inflammation is extremely rare. A case of intraperitoneal bladder rupture due to chronic cystitis is reported. Exploratory laparotomy and partial cystectomy were performed. Diagnosis and treatment are discussed.     

Bcl-2 proto-oncogene expression in low- and high-grade prostatic intraepithelial neoplasia

OBJECTIVE: To determine the incidence of bcl-2 protein expression in low- and high-grade prostatic intra-epithelial neoplasia (PIN) lesions, and to explore the role of bcl-2 in prostatic tumorigenesis. Materials and methods Immunoreactivity for bcl-2 was examined in 10 samples of benign prostatic hyperplasia (BPH), 13 of primary prostatic adenocarcinoma, 15 of high-grade PIN and 18 of low-grade PIN. All immunostaining results were scored for the approximate percentage of positive tumour cells and relative immunostaining intensity (score range 0-12). RESULTS: In all BPH samples, bcl-2 staining was detected consistently in the basal cell layer of the ducts and acini, but no staining was ever apparent in luminal cells. The immunoreactivity for bcl-2 was heterogeneous in the prostatic carcinomas and bcl-2 protein expression was present in six samples. In these six bcl-2-positive tumours, the mean (range) staining score was 1.15 (1-6). There was detectable expression of bcl-2 in low- and high-grade PIN in all cell layers; immunoreactivity was present in 10 of 15 high-grade PIN lesions, with a mean (range) score of 1.14 (1-4), and in 12 of 18 samples of low-grade PIN, with a mean (range) score of 1.77 (1-6). CONCLUSIONS: The high incidence of bcl-2 protein expression in low- and high-grade PIN lesions suggests that bcl-2 protein expression is associated with early prostate tumorigenesis.     

A comparative study of genotoxic effects in the treatment of trichomonas vaginalis infection: metronidazole or nalidixic acid

We performed a prospective randomized study to compare the potential genotoxic effects of metronidazole and nalidixic acid which they are used in the treatment of Trichomonas vaginalis infection. 20 patients with Trichomonas vaginalis infections participated in this study. 14 patients with vaginal trichomoniasis were treated with therapeutic doses of metronidazole 250 mg 3 times/d and six patients were treated with nalidixic acid 400 mg twice a day for 10 d. The genotoxic potential of a variety of mutagenic and carcinogenic agents can be evaluated by sister-chromatid exchange (SCE) test as a rapid cytogenetic test. An increased number of exchanges in lymphocytes reflects the influence of mutagens. No significant difference was observed in the SCE frequency of metronidazole treated patient however, a statistically significant increase (P<0.05) after nalidixic acid treatment could be described. We conclude that in spite of wide use of nalidixic acid for Trichomonas vaginalis infection, because of its potential genotoxic effect its usage must be individualized especially for pregnant women and small babies.     

Validation of 2001 Partin tables in Turkey: a multicenter study

OBJECTIVE: Although Partin tables were developed in United States to predict the stage of prostate cancer preoperatively, they are used by many clinics throughout the world assuming that these figures apply to their population as well. However the predictive value of current Partin tables, which was updated in 2001, has not been validated in most of the countries as well as in Turkey. Therefore, we evaluated the validity of 2001 Partin tables, for the ability to predict the pathological stage in Turkish patients. PATIENTS AND METHODS: The clinical and pathological findings of 1043 patients who have had radical prostatectomy were assessed. Serum PSA values, clinical stage, biopsy Gleason score and the pathological features of the radical prostatectomy specimens were collected from each clinic and evaluated. The predictive value of Partin nomogram and pathological findings of prostatectomy specimens were compared and analyzed according to Receiver Operating Characteristics (ROC) analysis. RESULTS: Median age of the patients was 60 (45-74). In the presented study, percentage of patients with clinical stage T1c was 43%. Patients with Gleason score of 2-4 in biopsy constituted 23.4% of the study group. In the present study, the ratio of the patients with serum PSA higher than 10 ng/ml was 39.6%. Organ confined disease, seminal vesicle involvement, lymph node metastases ratios were 64.7%, 10.3%, 1.8% respectively. Area Under Curve (AUC) values for organ confined disease, seminal vesicle involvement and lymph node involvement were calculated as 0.665, 0.733 and 0.759 respectively. CONCLUSION: It appears that Partin tables have a reasonable predictive value for the final pathological features like organ confined disease, seminal vesicle and lymph node involvement in Turkish patients. This multicenter study showed that current Partin tables could also be used in Turkish patients with comparable accuracy.     

Opposite-direction bilateral fracture dislocation of the shoulders after an electric shock

Injuries after an electric shock, such as dermal burns, motor and sensory nerve deficits, fractures and dislocations, are reported in the literature. Posterior dislocation of the shoulder after electric-shock is the common musculoskeletal injury. Bilateral dislocation, either anterior or posterior, is rarely seen and reported. We report a case of bilateral shoulder fracture dislocation in opposite directions following an electric-shock and discuss the mechanism, the diagnosis and the treatment.
