Renal involvement in the Laurence-Moon-Bardet-Biedl syndrome: report of five cases

.We report five patients with Laurence-Moon-Bardet-Biedl syndrome (LMBBS) who had renal involvement. Intravenous pyelography showed bilateral or unilateral calyceal clubbing and blunting in all patients. In addition, one patient had a parapelvic cyst in the left kidney and another had bilateral lobulated renal outlines of the fetal type. One patient had a urinary concentrating defect and two patients showed increased fractional sodium excretion. Estimated tubular phosphate reabsorption values were in normal limits in all of five patients. No patient had a urine acidification defect, proteinuria, glycosuria, or hyperaminoaciduria. One patient died from end-stage renal failure. The remaining four patients had normal serum creatinine values and estimated creatinine clearances. ^99mTechnetium-diethylenetriamine pentaacetate renal scanning showed prolonged and delayed concentration and delayed excretion in three of the four patients who survived. A focal scar was determined on the left kidney of one of four patients by ^99mtechnetium-dimercaptosuccinic acid renal scanning. All LMBBS cases with or without renal symptoms should be routinely evaluated for renal abnormalities. Renal scanning is a valuable method, especially for determining the renal involvement in the early stage of disease.

Bilateral immediate two-stage breast reconstruction in patients with unilateral breast cancer: Outcomes analysis and risk assessment

IntroductionContralateral prophylactic mastectomy has the potential to decrease the occurrence of cancer and reduce psychological burden. However, it is known that complications after bilateral mastectomy are higher compared with unilateral mastectomy. Our goal was to evaluate outcomes of immediate breast reconstruction in patients undergoing bilateral mastectomy and to compare complication rates between therapeutic and prophylactic sides.Patients and MethodsElectronic medical records of patients with unilateral breast cancer who underwent bilateral mastectomy and immediate reconstruction with expanders were reviewed. Postoperative complications were compared between therapeutic and prophylactic mastectomy sides.ResultsSixty-two patients were analyzed. The overall complication rate after both stages was 23.9% on the therapeutic side and 16.5% on the prophylactic side. Infection was the most common complication on both sides. All infections on the prophylactic mastectomy side were successfully treated with intravenous (IV) antibiotics (salvage rate of 100%), whereas 35.7% of infected tissue expander/implants on the therapeutic mastectomy side were explanted despite treatment.ConclusionCareful counselling of patients undergoing elective contralateral prophylactic mastectomy is essential as complications can develop in either breast after reconstruction.     

Clostridium difficile acquisition rate and its role in nosocomial diarrhoea at a university hospital in Turkey

Infection with Clostridium difficile can present with various clinical pictures ranging from an asymptomatic carrier state to pseudomembranous colitis and plays an important part in the etiology of nosocomial diarrhoea. To identify risk factors for C. difficile colonization and diarrhoea in hospitalized subjects, patients admitted to a general medicine ward at Marmara University hospital during a one year period were entered into the study. Of the 202 patients, nosocomial diarrhoea developed in 45 (22.3%). Fourteen patients (6.9%) were colonized with C. difficile during their hospitalization period. Ten of the colonized patients (71.4%) developed diarrhoea and were found to be positive by toxin assay. Pseudomembranous colitis was confirmed endoscopically in 3 of the patients with diarrhoea. Administration of beta lactam agents such as ampicillin and cephalosporins; gastrointestinal manipulations and admission to the intensive care unit were found as major risk factors for C. difficile colonization.     

Securing sustainable funding for viral hepatitis elimination plans

The majority of people infected with chronic hepatitis C virus (HCV) in the European Union (EU) remain undiagnosed and untreated. During recent years, immigration to EU has further increased HCV prevalence. It has been estimated that, out of the 4.2 million adults affected by HCV infection in the 31 EU/ European Economic Area (EEA) countries, as many as 580 000 are migrants. Additionally, HCV is highly prevalent and under addressed in Eastern Europe. In 2013, the introduction of highly effective treatments for HCV with direct‐acting antivirals created an unprecedented opportunity to cure almost all patients, reduce HCV transmission and eliminate the disease. However, in many settings, HCV elimination poses a serious challenge for countries’ health spending. On 6 June 2018, the Hepatitis B and C Public Policy Association held the 2nd EU HCV Policy summit. It was emphasized that key stakeholders should work collaboratively since only a few countries in the EU are on track to achieve HCV elimination by 2030. In particular, more effort is needed for universal screening. The micro‐elimination approach in specific populations is less complex and less costly than country‐wide elimination programmes and is an important first step in many settings. Preliminary data suggest that implementation of the World Health Organization (WHO) Global Health Sector Strategy on Viral Hepatitis can be cost saving. However, innovative financing mechanisms are needed to raise funds upfront for scaling up screening, treatment and harm reduction interventions that can lead to HCV elimination by 2030, the stated goal of the WHO.     

Comparison of different methods to detect <Emphasis Type="Italic">Helicobacter pylori</Emphasis> in the dental plaque of dyspeptic patients

The aim of this study was to compare different methods of detection of Helicobacter pylori (H. pylori) in the dental plaque of dyspeptic patients. After recording the clinical indices, culture and polymerase chain reaction (PCR) methods were performed on plaque samples, while rapid urease test in addition to these tests was carried on gastric samples from 67 dyspeptic patients who attended for an upper gastrointestinal endoscopy. Forty-seven of 67 patients were H. pylori-positive in gastric biopsy material whereas the microbial dental plaque from 19 patients demonstrated H. pylori positivity detected by PCR. Among the patients, 25.4% harbored H. pylori both in the stomach and in microbial dental plaque. No significant correlations were found among the presence of H. pylori in the stomach, in plaque, and clinical variables (P > 0.05). Although oral hygiene was observed optimal and the mean of pocket depth was not found to be higher, the prevalence of H. pylori was observed to be higher in dental plaque. According to our results, PCR technique gave the highest detection rate both in gastric biopsy and in dental plaque compared to the other methods used.     

Attitudes among medical and nonmedical university students toward the survivors of childhood abuse

ObjectiveChildhood sexual abuse (CSA) is increasing, and current studies should address issues such as stigmas and casual attitudes that may be amenable to intervention. Thus, we aimed to investigate the effects of education on the attitudes of medical students toward CSA survivors.MethodWe divided medical students into 2 groups: preclinical and clinical medical students. We compare the attitudes of nonmedical students with the attitudes of medical students with respect to survivors of CSA. All participants were asked to complete a questionnaire about stigmatization.ResultsThere were 572 students in our study, 347 of whom were enrolled in medical school. Of the 347 medical students, 151 were from the preclinical group, and 196 were from the clinical practice group. The remainder of the participants (n = 225) were in other fields of university. Of the medical students, 68.3% responded negatively about “asking a survivor of abuse to supervise their child for a few hours,” whereas 62.7% of the nonmedical students responded negatively. When asked, “What would you think if your child wanted to marry a survivor of sexual abuse?”, 72.9% of the medical students and 59.1% of the nonmedical students displayed negative attitudes toward that idea. Our research also found that significantly more preclinical students than clinical students would not want to be in a companionship/friendship with a CSA survivor at work (P = .015) or in their neighborhoods (P = .034).ConclusionBoth medical and nonmedical students seem to have negative thoughts about sexual abuse survivors, particularly when the issue involves their own children and/or social situations. Thus, the medical professionals must be careful and should avoid over interpretations of findings on childhood abuse studies that may lead to stigmatization.     

The potential effect of anatomic relationship between the femur and the tibia on medial meniscus tears

Background

The anatomic and the kinematical relationships between the femur and the tibia have been previously examined in both normal and diseased knees. However, less attention has been directed to the effect of these relationships on the meniscal diseases. Therefore, we aimed to investigate the impact of femorotibial incongruence on both lateral and medial meniscal tears.

Materials and methods

A total of 100 images obtained from MRI of 100 patients (39 males and 61 females) were included in the study. Diameters of the medial and the lateral femoral condyles, thicknesses of the menisci, and diameters of the medial and the lateral tibial articular surfaces were measured.

Results

The medial meniscus tear was detected in 40 (40 %) patients. However, no lateral meniscus tear was found. Significant relationships were found between the diameters of the posterior medial femoral condyle and the medial tibial superior articular surface and between the diameters of the posterior lateral femoral condyle and the lateral tibial superior articular surface. The mean values for the diameter of the medial condyle of the femur, the lateral condyle of the femur, the medial superior articular surface of the tibia, and the lateral superior articular surface of the tibia were found to be significantly higher in cases with meniscus tear compared to cases without meniscus tear. However, no significant difference was present regarding the thicknesses of the medial and the lateral menisci. A positive relationship between the diameter of the posterior medial femoral condyle and the tibial medial superior articular surface was found in cases with (n = 40) (r ² = 0.208, p = 0.003) and without tear (n = 60) (r ² = 0.182, p = 0.001). In addition, a significant positive relationship was found between the diameter of the posterior medial femoral condyle and the medial tibial superior articular surface in cases with and without tear.

Conclusion

The impact of femorotibial incongruence on the medial meniscus tear is important for the understanding of the lesions.
