Lower urinary tract symptoms and sexual dysfunction in women

This article assesses the effects of lower urinary tract symptoms (LUTS), not including urinary incontinence, on the overall sexual health of women, using literature that includes peer-reviewed articles. This article analyzes a number of studies that provide data on the prevalence and the predictors of sexual function impairment in women with LUTS, such as urinary urgency and frequency, overactive bladder syndrome, and interstitial cystitis. Because case studies provide substantial heterogeneity of outcome measures, this article does not apply meta-analytic techniques to the data. Most of the studies showed that LUTS can have a negative impact on the sexual health of women, sexual pain disorder being the more frequent complaint among patients with bladder dysfunctions.     

Intraoperative radiotherapy in the multidisciplinary treatment of bone sarcomas in children and adolescents

From September 1984 to December 1989, 38 patients of pediatric age with localized bone sarcomas received intraoperative radiotherapy (IORT) as part of a multidisci plinary treatment program. The age ranged from 6 to 21 years. The tumor histologies were 22 osteosarcomas and 16 Ewing's sarcomas. Thirty-four had initial primary disease (90%) and 4 were treated for local recurrence (10%). IORT was used on 32 untreated patients and in 6 previously treated with external beam radiotherapy (EBR). The IORT field included the surgically exposed tumor bed area. Single radiation doses ranging from 10 to 20 Gy were delivered, using 6–20 MeV electron beams. The median follow-up time for the entire group is 25 months (2–65+ months). The projected 5-year disease-free and overall survival rates are 65% and 69%, respectively. One patient developed a local recurrence in each histological group: one chondroblastic osteosarcoma and one cervical Ewing's sarcoma. Six patients died from metastatic progression: 3 initially recurrent tumors and three primary disease cases. Severe neuropathy and soft tissue necrosis were seen in some patients as IORT related complications. IORT is a feasible technique to be integrated in multidisciplinary programs that may promote local control in pediatric and adolescent patients with bone sarcomas. Peripheral nerves are dose-limiting tissue structures for IORT.     

Genetic polymorphisms in dopamine-related genes and smoking cessation in women: a prospective cohort study

Background  

Genes involved in dopaminergic neurotransmission have been suggested as candidates for involvement in smoking behavior. We hypothesized that alleles associated with reduced dopaminergic neurotransmission would be more common in continuing smokers than among women who quit smoking.     

Routine gallbladder screening not necessary in patients undergoing laparoscopic Roux-en-Y gastric bypass.

BACKGROUND: Management of the gallbladder in patients undergoing laparoscopic Roux-en-Y gastric bypass (LRYGBP) is controversial. We reviewed our experience in patients undergoing LRYGBP without routine gallbladder screening. METHODS: The data of 644 patients who underwent LRYGBP at our institution were analyzed. Preoperative ultrasonography was routinely obtained early in our series and selectively thereafter in patients with suspected symptomatic biliary disease. Cholecystectomy at LRYGBP was performed in symptomatic patients with positive ultrasound findings. Postoperatively, patients with intact gallbladders were prescribed ursodiol for 6 months. RESULTS: Of the 644 patients, 155 (24%) had history of cholecystectomy. A total of 104 patients underwent preoperative ultrasonography. Of the 104 patients, 20 had positive ultrasound findings and symptoms consistent with biliary disease and underwent concomitant cholecystectomy. Twelve patients had positive ultrasound findings and no biliary symptoms and did not undergo cholecystectomy. At a mean follow-up of 26.4 months, only 1 (8.3%) of the 12 patients had required cholecystectomy. Of the 104 patients, 72 had negative ultrasound findings. At a mean follow-up of 21.2 months, 5 of them (6.9%) had required cholecystectomy. The remaining 385 patients did not undergo any gallbladder screening. At a mean follow-up of 14 months, 32 (8.3%) of 385 patients had required cholecystectomy. Compliance with ursodiol for >4 months was only 39%. A time-to-event analysis did not reveal a significant difference in the cholecystectomy rate between asymptomatic patients with preoperative gallbladder screening and patients with no screening. CONCLUSION: Omission of gallbladder screening in asymptomatic patients undergoing LRYGBP is a reasonable approach that spares the patient a potentially unnecessary procedure with all its associated risks.     

Rates of intestinal absorption of molybdenum in humans.

The intestinal absorption of molybdenum in healthy human volunteers has been measured by simultaneous oral and intravenous administration of the stable isotopes 95Mo and 96Mo, and the results were analysed using the convolution integral technique. The results showed that molybdenum ingested in liquid form was rapidly and totally absorbed into the circulation under ordinary intake regimes. The rates and extent of absorption were lower for composite meals, and also for increasing levels of administration. This information can be helpful in the application of the new ICRP model of the human alimentary tract.     

Thrombophilic risk factors and unusual clinical features in three Italian CADASIL patients

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a genetically transmitted cerebrovascular disease. Typically, the first clinical manifestation is migraine and the full clinical spectrum of the disease with recurrent strokes of the subcortical type, cognitive, and mood disorders is seen during the fourth and fifth decades of life. Vascular risk factors are usually absent in CADASIL patients and the diagnosis of the disease is particularly suspected in young adults with cerebrovascular events of unknown cause, diffuse leukoencephalopathy on computed tomography or magnetic resonance imaging, and a history of cerebrovascular diseases or dementia in many family members. We describe three Italian CADASIL patients who presented to medical attention for cerebrovascular events occurred after the age of 55 and had, in addition to hypertension and hyperlipidemia, thrombophilic risk factors such as hyperhomocysteinemia, elevated levels of lipoprotein(a), and antiphospholipid antibodies. Symptoms possibly related to cortical involvement, such as dysphasia and visual field deficits, were reported by two of these patients. We conclude that a diagnosis of CADASIL should not be disregarded in patients with vascular risk factors and presenting with symptoms not immediately referable to subcortical damage at ages more advanced than commonly reported.
