In this retrospective report, the authors describe a rare case of spontaneous globe rupture from Klebsiella pneumoniae endophthalmitis in a middle-aged man with poorly controlled type 2 diabetes mellitus. There have been only four previously reported cases of spontaneous globe rupture from endophthalmitis. Out of the now five reported cases, all have been due to endogenous endophthalmitis, four have been due to gram-negative bacteria, and three have been due to K. pneumoniae. K. pneumoniae, especially the hypermucoid variant with a protective polysaccharide capsule, is an emerging pathogen with remarkable virulence...

The finding of collections of macrophages/histiocytes in lung biopsy and bronchoalveolar lavage is relatively common in routine practice. This morphological feature in itself is pathological, but the exact clinical significance and underlying disease should be evaluated together with clinical data, functional respiratory and laboratory tests and imaging studies.Morphological characteristics of macrophages and their distribution along the different pulmonary structures should be examined carefully by pathologists...

INTRODUCTION: Pneumocystis jirovecii pneumonia (PCP) can occur in HIV patients but also in those without HIV (non-HIV PCP) but with other causes of immunodeficiency including malignancy or rheumatic diseases. OBJECTIVE AND METHODS: To evaluate the clinical presentation and prognostic factors of non-HIV PCP, we retrospectively reviewed all patients diagnosed as having PCP without HIV at Kameda Medical Center, Chiba, Japan, from January 2005 until June 2012. For the purpose of examining a prognostic factor for non-HIV PCP with 30-day mortality, we compared the characteristics of patients, clinical symptoms, radiological images, Eastern Cooperative Oncology Group performance status (PS), and the time from the onset of respiratory symptoms to the start of therapy, in both survival and fatality groups...

Lana Ahmed Shinawi
BACKGROUND: The application of computer-aided design computer-aided manufacturing (CAD CAM) technology in the fabrication of complete dentures, offers numerous advantages as it provides optimum fit and eliminates polymerization shrinkage of the acrylic base. Additionally, the porosity and surface roughness of CAD CAM resins is less compared to conventionally processed resins which leads to a decrease in the adhesion of bacteria on the denture base, which is associated with many conditions including halitosis and aspiration pneumonia in elderly denture wearers...

We report a case of a brain abscess identified on fluorine-18 choline (FCH) positron emission tomography (PET) scan, which was not identified on fluorodeoxyglucose (FDG) PET scan. To our knowledge, there are no previous case reports of incidental brain abscess identified by FCH PET imaging. A 51-year-old man, with liver cirrhosis complicated by hepatocellular carcinoma (HCC) was enrolled in a research trial comparing HCC detection in FCH PET versus FDG PET. During the course of the trial, he underwent radiofrequency ablation (RFA) for HCC...

Dalbavancin is a lipoglycopeptide with a long half-life that allows infrequent dosing. It is indicated for the treatment of acute bacterial skin and skin structure infections caused by susceptible organisms, including Staphylococcus aureus and methicillin-resistant S. aureus (MRSA). Although this agent has been used off-label clinically, there are minimal data in infections outside the current indications. We report a case of a 28-year-old nonadherent male with HIV presenting with pneumonia due to MRSA that was treated with dalbavancin...

Metastasis to the breast from an extra-mammary malignancy has been documented in literature, however cervical cancer metastasis to the breast is very rare. Thirty-eight cases of metastatic deposit to the breast from cervical cancer have been reported in literature. Though most patients present with a breast lump, it is very difficult to clinically distinguish a primary breast malignancy from a metastatic deposit. Histopathology of the tissue, aided with immune-histochemical staining pattern provides a definitive diagnosis...

AIM: To investigate the range of pathologies treated by pancreas preserving distal duodenectomy (PPDD) and present the outcome of follow-up. METHODS: Neoplastic lesions of the duodenum are treated conventionally by pancreaticoduodenectomy. Lesions distal to the major papilla may be suitable for a pancreas-preserving distal duodenectomy, potentially reducing morbidity and mortality. We present our experience with this procedure. Selective intraoperative duodenoscopy assessed the relationship of the papilla to the lesion...

REVIEW
Richard G Wunderink, Grant Waterer
Community acquired pneumonia remains a common cause of morbidity and mortality. Usually, the causal organism is not identified and treatment remains empiric. Recent computed tomography and magnetic resonance imaging studies have challenged the accuracy of the clinical diagnosis of pneumonia, and epidemiologic studies are changing our perspective of what causes community acquired pneumonia, especially the role of viral pathogens and the frequent finding of multiple pathogens. The past decade has seen increasing overuse of empiric coverage of meticillin resistant Staphylococcus aureus and antibiotic resistant Gram negative pathogens owing to inappropriate application of guidelines for healthcare associated pneumonia...

BACKGROUND: Management of febrile neutropenia in pediatric patients is challenging. Chest X-ray and CT help to identify infective foci; however, exposure to radiation is a risk factor for development of secondary cancer. For this reason, attention is paid to reduce radiation exposure. OBJECTIVES: TTo define the role of LDCT examination in early detection of pulmonary lesions in children during oncology or autoimmune treatment complicated by neutropenia related fever...

BACKGROUND: Non-sexually active young females very rarely develop genital ulcers. Such ulcers pose a diagnostic challenge as well as physical and emotional distress for patients and family; therefore, the search for their etiology requires exhaustive investigation. Several viruses such as Epstein-Barr virus have been associated with this entity; however, Mycoplasma pneumoniae has rarely been linked to such ulcers in the literature. We present a case of vulvar ulcers in a non-sexually active young girl during the course of pneumonia caused by Mycoplasma pneumoniae...

Eun-Young Kwon, Gil Sun Cha, Ji-Young Joo, Ju-Youn Lee, Jeomil Choi
PURPOSE: Epitope spreading is a phenomenon in which distinct subdominant epitopes become major targets of the immune response. Heat shock protein (HSP) 60 from Porphyromonas gingivalis (PgHSP60) and peptide 19 from PgHSP60 (Pep19) are immunodominant epitopes in autoimmune disease patients, including those with periodontitis. It remains unclear whether Pep19 is a dominant epitope in subjects without periodontitis or autoimmune disease. The purpose of this study was to determine the epitope spreading pattern and verify Pep19 as an immunodominant epitope in healthy teenagers using dot immunoblot analysis...

Adult community-acquired pneumonia (ACAP) is the most prevalent pulmonary infectious disease that may be asymptomatic or have varying clinical presentations. Patients with ACAP often present with enlarged mediastinal lymph nodes on their chest computed tomography images. However, large irregular swollen lymph nodes are rarely reported in ACAP, and may therefore be confused with enlarged lymph node masses. In the present case report, the patient presented with lymph node masses, which were ameliorated to their normal size following antimicrobial treatment...
