Immediate development of post-varicocelectomy hydrocele: a case report and review of the literature
Management of hydrocele in adolescent patients
Hydrocele is defined as an abnormal collection of serous fluid in the potential space between the parietal and visceral layers of the tunica vaginalis. In the majority of affected adolescents, hydrocele is acquired and is idiopathic in origin. The pathogenesis of idiopathic hydrocele is thought to be an imbalance in the normal process of fluid production and reabsorption. The diagnosis is usually clinical. Taking a thorough history is essential to rule out any fluctuation in size, which is an indication of a patent processus vaginalis. Scrotal ultrasonography is mandatory in nonpalpable testicles to rule out a subtending testicular solid mass requiring inguinal exploration. Otherwise, open hydrocelectomy via a scrotal incision is the standard treatment of idiopathic hydroceles. The second most common cause of hydrocele in adolescents is varicocelectomy. The risk of hydrocele formation is higher with non-artery-sparing procedures or those performed without microsurgical aid, and in surgery requiring cord dissection. If hydrocele occurs after varicocelectomy, initial management should include observation with or without hydrocele aspiration. Large persistent hydroceles are best served by open hydrocelectomy
Epidemiology of intra-abdominal infection and sepsis in critically ill patients: “AbSeS”, a multinational observational cohort study and ESICM Trials Group Project
Purpose: To describe the epidemiology of intra-abdominal infection in an international cohort of ICU patients according to a new system that classifies cases according to setting of infection acquisition (community-acquired, early onset hospital-acquired, and late-onset hospital-acquired), anatomical disruption (absent or present with localized or diffuse peritonitis), and severity of disease expression (infection, sepsis, and septic shock). Methods: We performed a multicenter (n = 309), observational, epidemiological study including adult ICU patients diagnosed with intra-abdominal infection. Risk factors for mortality were assessed by logistic regression analysis. Results: The cohort included 2621 patients. Setting of infection acquisition was community-acquired in 31.6%, early onset hospital-acquired in 25%, and late-onset hospital-acquired in 43.4% of patients. Overall prevalence of antimicrobial resistance was 26.3% and difficult-to-treat resistant Gram-negative bacteria 4.3%, with great variation according to geographic region. No difference in prevalence of antimicrobial resistance was observed according to setting of infection acquisition. Overall mortality was 29.1%. Independent risk factors for mortality included late-onset hospital-acquired infection, diffuse peritonitis, sepsis, septic shock, older age, malnutrition, liver failure, congestive heart failure, antimicrobial resistance (either methicillin-resistant Staphylococcus aureus, vancomycin-resistant enterococci, extended-spectrum beta-lactamase-producing Gram-negative bacteria, or carbapenem-resistant Gram-negative bacteria) and source control failure evidenced by either the need for surgical revision or persistent inflammation. Conclusion: This multinational, heterogeneous cohort of ICU patients with intra-abdominal infection revealed that setting of infection acquisition, anatomical disruption, and severity of disease expression are disease-specific phenotypic characteristics associated with outcome, irrespective of the type of infection. Antimicrobial resistance is equally common in community-acquired as in hospital-acquired infection
Irregular stone masonries: Analysis and strengthening with glass fibre reinforced composites
Accidental poisoning with Aconitum: Case report and review of the literature
Aconitine intoxication by ingestion of Aconitum roots can lead to ventricular tachycardia and cardiac arrest and provides an example of the potential effect of self-medication. Educational campaigns should be implemented to contain acute intoxications caused by herbal-derived products
Irregular stone masonries: Analysis and strengthening with glass fibre reinforced composites
Two masonry types with irregular texture are analysed to evaluate mechanical properties, sources of vulnerability and to design proper strengthening interventions. Direct surveying, laboratory and in situ tests were performed to evaluate morphological characteristics and mechanical properties. Experimental values were compared with results obtained from analytical and FEM homogenizations, which exploited automated image segmentation process to determine volume fractions and description of the Reference Volume Element. Strips of Glass Fabric-Reinforced Cementitious Matrix and transversal bars were considered and tested as strengthening solutions to overcome irregular masonries limits derived from multi-leaf structure highlighting levels of capacity improvement
Mobility, hydrocephalus and quality of erections in men with spina bifida
Introduction
Little is known about erectile dysfunction (ED) among men with spina bifida (SB). The goal of this study was to determine quality of erections and possible factors affecting erections in this population. It was hypothesized that men who ambulate and do not have a ventriculoperitoneal shunt (VPS) are more likely to have erections sufficient for intercourse.
Methods
An online survey was administered over an 18-month period to men aged >= 18 years and with SB. Participants were recruited through local, national and international SB organizations via social media. Exclusion criteria were: poor English proficiency, not completing the questionnaire or missing information regarding erections, VPS or ambulation. Data were collected on demographics, previous surgeries and function. Ambulatory status was classified using the Hoffer classification (Hoffer et al., 1973). Those able to walk at least at home, with or without crutches/braces, were classified as "ambulators." Erections were assessed using a single question from the validated Expanded Prostate Cancer Index Composite questionnaire (e.g. normal: "firm enough for intercourse"). Logistic regression was used for statistical analysis.
Results
The median age of 122 participants was 33 years, 53.3% were ambulators and 70.5% had a VPS. Overall, 41.0% reported normal erections. Ambulators were more likely to report normal erections than non-ambulators (63.1% vs 15.8%, P = 8.65, P = 0.32 and P = 0.62, respectively).
Discussion
Approximately 59% of men with SB reported ED, with ambulators being far more likely to have normal erections. This suggests that ambulatory status, similar to neurological lesion level, is a confounder of erectile function in the SB population. A limitation of the study was that a single item was used to assess erectile function. Rather than performing a comprehensive analysis of sexual health, the study aimed to gauge the prevalence of normal erections and assess possible risk factors. It did not assess sexual activity, erection duration or ED treatments. However, this is the largest study, to date, on SB and erectile quality with international participants.
Conclusion
About 40% of men with SB reported normal erections. Ambulatory status, rather than hydrocephalus, appeared to be the primary factor associated with erectile function. Approximately 2/3 of ambulators and 1/6 of non-ambulators reported normal erections
