Pain during sexual activity and ejaculation following hernia repair: A retrospective comparison of transabdominal preperitoneal versus Lichtenstein repair

Pain during sexual activity and ejaculation are the unspoken long-term complications of groin hernia repair. Laparoscopic surgical techniques are associated with decreased post-operative pain and earlier return to daily activities, but its effect on these complications is unclear. This study aims to investigate the effect of transabdominal preperitoneal repair (TAPP) on de-novo pain during sexual intercourse and ejaculation and to compare with open repair. For this reason, two groups were determined according to the surgical technique: the Lichtenstein repair and the TAPP groups and a questionnaire was sent to the patients a minimum of 6 months following the surgery. A total of 317 patients included, as 115 in TAPP and 202 in Lichtenstein repair group. No significant difference was observed concerning pre-operative pain during sexual activity and ejaculation in both groups (p = .75, p = .56). Following the surgery, the number of patients experiencing painful sexual activity was significantly higher in the Lichtenstein repair group compared to the TAPP group (19.3% vs. 11.3%, respectively, p = .03). The post-operative painful ejaculation rate was also significantly lower for the TAPP group (p = .04). The lower rates of post-operative dysejaculation and pain during sexual activity can be achieved with the advantage of laparoscopic surgery.     

Right ventricular free wall perforation during pericardiocentesis,and an inappropriate device selection for percutaneous treatment

Right ventricular (RV) perforation is a rare but life‐threatening complication of pericardiocentesis and is usually treated surgically. We presented a case of RV free wall perforation, which occurred during pericardiocentesis and tried to be closed percutaneously with the Amplatzer vascular plug‐III (AVP‐III) device. The occluder device sealed the perforation, but it was in an insecure position; therefore, the patient underwent surgical repair. As an AVP‐III device, with a middle disk thicker than the RV myocardium, it may cause the RV myocardium to stretch outwards, so it should not be used for the treatment of RV perforation by the transcatheter way.     

A New Approach to Tertiary Hyperparathyroidism: Percutaneous Embolization: Two Case Reports

Secondary hyperparathyroidism is one of the most common complications of chronic kidney failure. If prolonged, parathyroid hormone release gains autonomy and tertiary hyperparathyroidism with parathyroid adenoma or hyperplasia can be develop. Tertiary hyperparathyroidism is associated with increased risk of mortality and morbidity; thus, treatment is recommended. Medical treatment includes phosphate binders, vitamin D analogues, and calcimimetic agents. Most cases of tertiary hyperparathyroidism can be controlled with medical treatment. When medical treatment options prove insufficient, parathyroidectomy is recommended. However, recurrence after parathyroidectomy is possible, which requires an alternative treatment. We present our percutaneous embolization experience, which has not been tried in the treatment of tertiary hyperparathyroidism in renal transplantation patients diagnosed with tertiary hyperparathyroidism.     

Determination of serum bile acids routinely may prevent delay in diagnosis of total parenteral nutrition-induced cholestasis

BACKGROUND/PURPOSE: Early diagnosis of development of cholestasis is a current major problem for patients receiving total parenteral nutrition (TPN). Conventional tests for hepatic function such as serum transaminases and alkaline phosphatase do not often reflect simultaneously histopathologic changes of the liver. The aim of this study is to find out the relationships between conventional hepatic function tests, total serum bile acid concentrations (TSBA), and the histopathologic changes in the liver during TPN administration in rats. METHODS: Forty Albino rats were divided into four experimental groups, each consisting of 10 rats, as follows: control group (C), 0.9% saline for 14 days; T7 group, TPN for 7 days; T14 group, TPN for 14 days; T7O7 group, TPN for 7 days and then 0.9% saline for the next 7 days. All solutions were administered by infusion through intraperitoneal catheter in two equal doses. During the experiment, rats also maintained on rat chow and water ad libitum. Levels of serum glutamic oxaloacetic transaminase, glutamic pyruvic transaminase, alkaline phosphatase, and TSBA were measured. Liver was evaluated histopathologically by light microscope and then Morphological Cholestasis Index (MCI) was calculated. RESULTS: Cholestasis was present in all experimental groups except control. Levels of transaminases and alkaline phosphatase were not correlated with the histopathologic changes (P > .05), but TSBA concentrations were correlated with MCI in all groups (P< .01). TSBA concentrations and MCI in all groups also were correlated with the duration of exposure with TPN (P< .01). CONCLUSIONS: Measurement of TSBA seems to be more sensitive in early diagnosis of TPN-induced cholestasis. Therefore, periodical determination of TSBA during TPN administration can be done routinely.     

Positron emission tomography in the clinical staging of patients with Stage I and II testicular germ cell tumors

OBJECTIVES: To evaluate the accuracy of fluorodeoxyglucose positron emission tomography (PET) compared with computed tomography (CT) staging in patients with Stage I and II testicular germ cell tumors (GCTs). METHODS: From January 1995 to July 1997, in 37 patients with clinical Stage (CS) I (n = 25) and CS II (n = 12) GCT (24 nonseminomas, 13 seminomas), PET and CT were compared in the initial staging. After PET, the patients with nonseminomatous GCT were staged surgically by retroperitoneal lymph node dissection and the patients with seminomatous GCT were followed up clinically. RESULTS: Correct staging by PET was achieved in 34 of 37 patients compared with correct CT staging in 29 of 37 patients. Of 10 metastatic lesions, 7 and 4 were detected by PET and CT, respectively. PET did not show false-positive signals. PET was unable to detect vital cancer with a maximal diameter less than 0.5 cm or teratoma at any size. CONCLUSIONS: PET was useful for detecting viable tumor in lesions that are visible on CT scan and, thus, it may omit false-positive CS II lesions. However, PET was not able to identify mature teratoma. In this study, PET did not improve the staging in patients with CS I tumor.     

Influence of chronic morphine exposure on serum LH, FSH, testosterone levels, and body and testicular weights in the developing male rat

Opiate abuse has been a matter of serious concern in male adolescents. This study investigates the effects of chronic morphine administration on serum luteinizing hormone (LH), follicle-stimulating hormone (FSH), testosterone levels, testicular histology, and body and testes weight in developing male rats. Animals were subcutaneously injected with morphine (5 mg/kg) or saline (1 mL/kg) twice daily for 30 days. Body weight determinations and injections were carried out under light ether anesthesia. At the end of the experiments, the rats were decapitated and blood samples were collected. Serum levels of LH and FSH were measured. Chronic morphine administration significantly decreased decreased serum testosterone (p < .02) and LH (p < .01) levels, but not FSH release compared to controls. Morphine exposure reduced body weight (p < .01), but had no significant effect on the testicular weight. When the testicular tissue was histologically examined, structural features of the seminiferous tubules and Leydig cells were similar in both saline and morphine-treated animals. The results suggest that opiates affect testosterone release through the hypothalamo-hypophyseal-gonadal axis rather than by a local testicular mechanism. Chronic morphine exposure during sexual maturation may have long-term endocrine disturbances in male rats.     

Retinal tears associated with panuveitis and Behçet's disease

To report retinal tears formation in 3 eyes of 2 patients with active panuveitis and Beh?et's disease. We describe 2 patients that were diagnosed and treated for Beh?et's disease with active panuveitis. Retinal tears developed while the inflammation was active. The patients were treated with topical, oral steroids, and cyclosporine therapy for bilateral panuveitis. One patient presented with a retinal tear located at the periphery of the active retinal lesion. The other had multiple tears associated with active retinal lesions in both eyes. Argon laser photocoagulation was performed in both patients as soon as the tears were detected. Ocular inflammation was controlled with this therapy, and only a few mild flare-ups occurred. The patients have been followed up for 8 and 16 months, respectively. During this period no new retinal tears have developed. Although retinal tear formation is rarely associated with Beh?et's panuveitis, the clinician should be aware of this as a possible complication. When structural changes are present in the vitreous, detailed ophthalmoscopy is indicated to assess for retinal tears. If a tear is detected in a patient with panuveitis and Beh?et's disease, laser photocoagulation therapy should be performed immediately to prevent retinal detachment.     

The Efficacy of Fluoxetine in the Treatment of Premature Ejaculation: A Double-Blind Placebo Controlled Study

Purpose

The efficacy of the selective serotonin re-uptake inhibitor fluoxetine in the treatment of premature ejaculation was examined.

Materials and Methods

The study comprised 17 patients with premature ejaculation who presented to the urology clinic of our medical school. In this double-blind study the patients were randomized into treatment groups receiving 20 mg. fluoxetine daily for 1 week and 40 mg. daily afterward (group 1) or 1 capsule placebo daily for 1 week and 2 capsules daily afterward (group 2). The groups were evaluated according to the latent period of intravaginal ejaculation.

Results

The latent period of intravaginal ejaculation in group 1 was significantly longer than that in group 2. Nausea, headache and insomnia were reported side effects.

Conclusions

Fluoxetine may be regarded as a safe and effective alternative in the treatment of premature ejaculation.
