RESUMEN
Peritonitis is a very serious complication encountered in patients undergoing peritoneal dialysis and healthcare providers involved in the management should be very vigilant. Gram-positive organisms are the frequent cause of peritonitis compared to gram-negative organisms. There has been recognition of peritonitis caused by uncommon organisms because of improved microbiological detection techniques. We report a case of peritonitis caused by Moraxella osloensis (M. osloensis), which is an unusual cause of infections in humans. A 68-year-old male, who has been on peritoneal dialysis for 2 years, presented with abdominal pain and cloudy effluent. Peritoneal fluid analysis was consistent with peritonitis and peritoneal fluid culture grew gram-negative bacteria. M. osloensis was identified by 16 S PCR phenotypic and sequencing techniques. Patient responded well to the treatment, with intraperitoneal cephalosporin, and repeat peritoneal fluid culture yielded no growth. M. osloensis rarely causes infection in humans and responds well to treatment, as reported in literature.
RESUMEN
OBJECTIVES: Use of high-dose statin therapy (HDST) in patients with stroke became standard clinical practice after the Stroke Prevention by Aggressive Reduction in Cholesterol Levels (SPARCL) study, in which the mean age of the study population was approximately 63 years. Little data are available on the adverse effects of statins when used in high doses in adults older than 65 years. The objective of this study was to assess the magnitude of adverse effects of HDST in geriatric patients. METHODS: This single-center, retrospective, case-control study was conducted at Upstate Medical University, Syracuse, New York. All patients older than 65 years admitted between 2008 and 2011 to the hospital's Upstate Stroke Center with acute stroke were eligible. Electronic medical records of 200 eligible patients were reviewed to collect demographic, clinical, and laboratory data. Patients on HDST (cases) were compared with those on low doses (controls) using the χ, Fisher exact (two-sided), and Student t tests. RESULTS: One hundred cases (mean age 80.5 ± 7.7 years) were compared with 100 controls (mean age 78.9 ± 6.4 years). Sixty-seven percent were taking simvastatin. Ninety percent of the cases compared with 81% of the controls had ischemic stroke. The prevalence of elevated alanine aminotransferase (13%) and myositis (4%) was significantly higher in the cases than in the controls. Fourteen percent of the cases reported myalgias, 9% had nausea, and 6% had diarrhea. Seventy-three cases had low-density lipoprotein levels <100 mg% and 41% of the cases had mean glycated hemoglobin levels ≥ 6.5%. CONCLUSIONS: The use of HDST in older adult patients with acute stroke is associated with a significantly increased burden of liver enzyme elevation and myalgias.

We present a case of hypercalcemia in a 79-year-old female likely secondary to uterine leiomyoma. To the best of our knowledge, hypercalcemia due to a benign tumor has only been described in five cases. Of these above five cases, uterine leiomyoma was thought to be the cause of hypercalcemia in three cases.
RESUMEN
Yersinia enterocolitica is primarily a gastrointestinal tract pathogen known to cause gastroenteritis, although it may produce extra-intestinal infections like sepsis and its sequelae. However, primary cutaneous infections are extremely rare. We present a case of Y. enterocolitica thigh abscess in an immunocompetent adult. The portal of entry is unclear in this case. He did many outdoor activities that involved skin injuries and exposure to soil and contaminated water. Hence, direct inoculation as a result of exposure to contaminated water is postulated in the absence of evidence for a gastrointestinal route of infection.
