Candida glabrata is a commensal yeast of the gastrointestinal tract and skin humans. However, it causes opportunistic infections in immunocompromised patients, second most common pathogen causing bloodstream infections. Although there are many studies on epidemiology C. infections, fine- large-scale geographical nature remain incompletely understood. Here we investigated both population structure through genome sequencing 80 clinical isolates obtained from six tertiary hospitals Qatar by...
BackgroundCentral nervous system (CNS) viral infections are an important cause of morbidity and mortality. No data available regarding their epidemiology in Qatar.DesignWe retrospectively evaluated all cerebrospinal fluid findings from January 2011–March 2015 at Hamad Medical Corporation. Those with abnormal CSF finding were included our study. We excluded those missing medical records, no clinical evidence CNS infection, or proven bacterial, fungal tuberculosis infection. classified as...
Candida auris is an emerging, multidrug-resistant fungal pathogen that has become a public health threat with increasing incidence of infections worldwide. spreads easily among patients within and between hospitals. Infections outbreaks caused by C. have been reported in the Middle East region including Oman, Kuwait, Saudi Arabia, Qatar; however, origin these isolates largely unknown. Pathogen whole genome sequencing (WGS) was used to determine epidemiology drug resistance mutations Qatar....
BACKGROUND:Cytotoxic lesions of the corpus callosum (CLOCC) is a rare clinical and radiological syndrome that has been associated with various infectious etiologies. CLOCC are among recently described neurological associations severe acute respiratory coronavirus 2 (SARS-CoV-2) infection in patients disease 2019 (COVID-19). We report case man SARS-CoV-2 who presented auditory hallucinations rapidly developed systemic inflammatory response (SIRS). CASE REPORT:A 23-year-old no past medical...
BACKGROUND:Primary pituitary tuberculosis (in absence of other organ involvement and constitutional symptoms) is an extremely rare disease with total reported cases in the literature fewer than a hundred. Misdiagnosis as adenoma common late diagnosis can result permanent endocrine dysfunction and/or long-term neurologic sequelae. CASE REPORT:We report on case middle-aged woman who presented severe headache left third cranial nerve palsy. Magnetic resonance imaging (MRI) revealed large tumor...
Schistosomiasis is the third most widespread devastating parasitic disease worldwide and has a high mortality burden. Neuroschistosomiasis one of rare severe clinical presentations disease. It caused by granuloma formation around eggs that lodge in central nervous system, with Schistosoma japonicum usually causing reported cerebral Three unusual schistosomiasis Qatar are described herein. The three patients were young males who presented seizures tumor-like lesions on brain imaging....
Pulmonary complications in leptospirosis, though common, are often unrecognized a non-endemic area. We report here patient with leptospirosis and severe pulmonary involvement who was treated meropenem (1 g every 8 hours), moxifloxacin (400 mg once daily), high doses of corticosteroids. Systemic steroids were continued for 3 months because persistent lesions.
Infection due to Nocardia is reported mainly in immunocompromised patients. It usually presents as a pulmonary or disseminated disease with predilection for the brain. Infections are rare etiology of intracranial vascular aneurysms. Herein we report case otitidiscaviarum (N. otitidiscaviarum) young female newly diagnosed systemic lupus erythematosus (SLE) complicated by development an infectious aneurysm. To best our knowledge this fourth nocardial infection-related aneurysm and second N....
Abstract Objective To report acute multifocal retinitis in association with serologically-proven Coxiella (C) Burnetii infection (Q fever) endocarditis. Material and methods A single case documented multimodal imaging. Results 67-year-old cattle breeder presented a 2-week history of persistent fever, headache, floaters both eyes. On examination, his best-corrected visual acuity was 20/20, there 1+ vitreous cells Bilateral fundus examination showed multiple small superficial white retinal...
Mucor is an angioinvasive fungus that was reported mainly in immunocompromised patients. It usually presents as rhino-orbital, pulmonary, gastrointestinal, and disseminated disease. Isolated renal mucormycosis extremely rare infection immunocompetent patients associated with high fatality rate. Early diagnosis, prompt antifungal treatment, surgery give the patient best chance for cure survival. We describe herein a case of zygomycosis caused by Apophysomyces elegans (A. elegans) host. To our...
Abstract Rhodotorula mucilaginosa is an emerging fungal infection with the ability of biofilms formation. The identification R fungemia should trigger reflexes prompt central venous line removal and using Amphotericin therapy.
Tuberculous mastitis (TBM) is relatively rare disease with an incidence ranging between 0.1 and 4%. Most of the cases are culture negative often mistaken chronic benign idiopathic granulomatous (IGM). It very crucial to distinguish TBM from other causes as treatment differs tremendously. We describe here in a young woman originally India residing Qatar; non endemic area tuberculosis; for more then fifteen years. She presented 2 months history right breast mass, followed by low grade fever,...
The non-typhoid Salmonella (NTS) species are commonly associated with gastroenteritis and other forms of intestinal disease. Thoraco-pulmonary infections less reported. We describe the case a 66-year-old Qatari lady who presented subacute cough. Chest imaging revealed multiple pulmonary pericardial cavitary lesion air fluid levels. Bronchoalveolar lavage culture grew group D. patient was treated 4 weeks appropriate antibiotics. Clinical radiological improvement were documented on subsequent...
Fungal infections of self-sealing corneal incisions in cataract surgery are scarce. We report a case Alternaria keratitis, several weeks after uneventful clear-cornea phacoemulsification.A 42-year-old woman, with history retinitis pigmentosa, complained painful red right eye, 45 days phacoemulsification. Slit-lamp examination revealed multiple snow-like contiguous stromal infiltrates, irregular margins, and no epithelial defect. These infiltrates were unresponsive to topical quinolones...
BACKGROUND:Recently, the use of cardiac implantable electrophysiological devices (CIEDs) has increased. Advances in medical technology, an increasingly aging population, increases clinical indications, and expanded insurance coverage for these have all contributed to this trend. Infection is considered be one most serious complications CIEDs carries a significant risk morbidity mortality. Although infection with Staphylococcus sp. accounts majority cases, other bacteria been implicated as...
Background: Esophageal adenocarcinoma (EAC) is highly aggressive and characterized by poor prognosis.AXL expression has been linked to Barrett's tumorigenesis resistance chemotherapy, which associated with c-ABL intracellular localization.However, the molecular functional relationship between AXL clinical significance of co-expression these proteins in EAC remain unclear.Methods: We used immunohistochemical analysis (IHC) on tissue microarrays containing human samples (n=53) normal...
Abstract The aim of the current study is to review molecular characteristics Neisseria meningitidis ( N. ) in Hamad Medical Corporation, which provider secondary and tertiary care state Qatar. A total 39 isolates from period 2013 2018 were revived identified by Vitek, susceptibility on basis E test was retrieved patient’s files. subjected multilocus sequence typing. most common serogroup (19) W135, 12 isolated blood CSF. ST-11 predominant ST clonal complex causing cases (61.53%). Clonal...
Background Cryptococcosis is a major opportunistic invasive mycosis that mostly affects immunocompromised patients.Methods This was an observational study of all culture-confirmed cases cryptococcosis conducted in the State Qatar from January 2005 to December 2016.

Four patients had Human Immunodeficiency Virus (HIV) infection with...
Purpose: To report a case of central retinal artery occlusion associated with sildenafil intake and briefly discuss its causative pathogenesis.
