Acute coronary syndromes with significant troponin increase in patients with hip fracture prior to surgical repair: differential diagnosis and clinical implications

Myocardial infarction after hip fracture but before surgical repair is associated with a 30-day mortality as high as 30 % at 1 month. In Florence, since 2011, hip fractures are referred to a multidisciplinary hip fracture team including internal medicine specialists, anesthesiologists, and orthopaedic surgeons. The aim of the present investigation was to evaluate the clinical characteristics of patients with hip fracture who had at hospital admission a significant increase of troponin (>10 times reference levels), the diagnostic and therapeutic strategies adopted, and overall 1-year survival. Protocol at admission included careful clinical evaluation (including bedside echocardiography) in order to stratify surgical risk and schedule surgery and anaesthesiology strategy. 21/1025 patients had preoperative significant troponin increase. In sixteen patients, a diagnosis of NSTEMI was made, five presented with ST elevation. In five patients with NSTEMI considered at very high surgical risk (ASA ≥ 3, severe cognitive and functional impairment), surgery was not performed. None survived at 1 year. Hip surgery was performed in the other 11. Four underwent coronary revascularization after hip surgery. In this group, 1-year survival was 80 %. Four of five ST elevation patients fulfilled criteria for stress cardiomyopathy confirmed by angiography. Hip surgery was performed, and the patients are alive at 1-year follow-up. Close to 2 % of patients with hip fracture are found to have a significant troponin increase before surgery. Three out of four have an NSTEMI diagnosis. In patients undergoing hip surgery, survival at 1 year is close to 80 %. In patients with ST elevation at admission, stress cardiomyopathy should be considered in the differential diagnosis. This clinical condition is associated with a favourable prognosis after hip surgery.     

Transarterial chemoembolization for liver metastases from solid pseudopapillary epithelial neoplasm of pancreas: A case report

Solid pseudo-papillary epithelial neoplasm(SPEN) is a rare epithelial tumor of pancreas with a low malignant potential occurs most commonly in young females. We report a case of 40 years old woman presented withextensive liver metastasis from SPEN of pancreatic body for which she was operated four years ago. Due to the extensive nature of metastatic disease she was offered Transarterial chemoembolisation(TACE) using gemcitabine as chemotherapeutic agent. Short term follow up after a month of TACE with multiphase computed tomography showed > 90% resolution in the viable tumor with significant clinical improvement. TACE ensures targeted delivery of chemotherapeutic drugs in higher doses with least systemic toxicity and is more effective and safe than systemic chemotherapy. TACE with gemcitabine was found to be very effective in our patient with numerous liver metastasis.     

One-stage revision in two cases of Salmonella prosthetic hip infection

We describe two cases of prosthetic joint infection (PJI) of the hip due to Salmonella. The first patient presented with an early infection 5 d after being discharged following a total hip replacement and the second patient presented at the emergency ward with a late infection, thirteen years following a total hip replacement. Both cases occurred within one month of each other at our institution and both were successfully treated with a one-stage revision. PJI caused by Salmonella species is very rare: so far only 20 Salmonella PJIs of the hip have been described. Therefore, full consensus on the best treatment approach has not yet been reached. An aggressive two-stage approach is advised because of the virulence of Salmonella, although a limited number of successful one-stage approaches have been described as well. According to the latest guidelines, one-stage revision has comparable success rates and less morbidity compared to two-stage treatment, when selecting the right patients. In our opinion, PJI caused by Salmonella should be treated just as PJI caused by other bacteria, with consideration of the selection criteria as mentioned in several treatment guidelines. As illustrated by these two cases, one-stage revision can be successful in both early and late Salmonella PJI of the hip.     

Seroprevalence and factors associated with herpes simplex virus type 2 among HIV-negative high-risk men who have sex with men from Rio de Janeiro, Brazil: a cross-sectional study

Background  

Herpes simplex virus type 2 (HSV-2) is the leading cause of genital ulcer disease in developing countries, including Brazil, and is especially prevalent among men who have sex with men (MSM). HSV-2 infection represents a risk factor for the acquisition and transmission of other sexually transmitted diseases. The goal of the present cross-sectional study was to estimate HSV-2 seroprevalence and to determine the factors associated with HSV-2 seropositivity in HIV-negative high-risk MSM from Rio de Janeiro, Brazil.     

Periodontal and soft tissue prevention strategies for the adolescent dental patient

Recent research has refocused attention on the contribution of periodontal health to the general health of patients at various ages. This article describes changes in the periodontal tissues of adolescent dental patients related to hormonal fluctuations, lack of proper oral hygiene, and risk-taking behaviors. Attention is placed on the development and prevention of acute and chronic gingival conditions in addition to gingival tissue enlargement as one side effect of certain medications.     

Oral health issues for women athletes

More women are participating in sports at all levels. This article presents information for dental professionals to enhance awareness of emerging issues in women's oral health, with specific emphasis on female athletes. These issues include the prevalence, prediction, and prevention of sports-related traumatic orofacial injuries as well as fads and habits such as tongue piercing, smokeless tobacco, eating disorders, and performance-enhancing drugs.     

Mycobacterium aurum bacteremia in an immunocompromised child

Mycobacterium aurum was cultured from the Broviac catheter of a 5-year-old child with metastatic Wilms tumor. Removal of the catheter resulted in prompt resolution of the fever and sterilization of the blood culture. This rapidly growing mycobacterium, previously believed to be a commensal, can cause disease in the immunocompromised host.
