Background In this large-scale cluster-randomized controlled trial (cRCT) we sought to assess the effectiveness of facemasks against viral respiratory infections. Methods and results Over three consecutive Hajj seasons (2013, 2014, 2015) pilgrims' tents in Makkah were allocated 'facemask' or 'no facemask' group. Fifty offered participants intervention tents, be worn over four days, none control tents. All recorded facemask use symptoms health diaries. Nasal swabs collected from symptomatic...
Brucellosis is one of the most common zoonotic disease affecting humans and animals endemic in many parts world including Gulf Cooperation Council region (GCC). The aim this study was to identify species determine antimicrobial susceptibility pattern Brucella strains isolated from clinical specimens, Qatar.We evaluated 231 isolates. All isolates were identified as B. melitensis. susceptible doxycycline, tetracycline, streptomycin, gentamicin, trimethoprim / sulfamethoxazole ciprofloxacin...
Antimicrobial resistance (AMR) is a global healthcare challenge with substantial morbidity, mortality, and management costs. During the COVID-19 pandemic, there was documented increase in antimicrobial consumption, particularly for severe critical cases, as well noticeable travel social restriction measures that might influenced spectrum of AMR. To evaluate problem, retrospective data were collected on bacterial infections susceptibility patterns Qatar before after pandemic from 1 January...
Clostridium difficile infection (CDI) is not generally reported to public health authorities in the Middle East and its true prevalence remains largely unknown. The aims of this study were determine CDI associated ribotypes among C. isolates Qatar. Influence age correlation with other risk factors e.g. proton pump inhibitor use, antibiotic existence chronic conditions, etc was also investigated for positive patients. A total 1,532 patients suspected recruited from two hospitals between 2011...
Community-acquired urinary tract infection (UTI) is the most common caused by extended-spectrum beta-lactamase (ESBL)-producing organisms.to estimate prevalence of ESBL-UTI in adults and to identify potential risk factors that may predispose ESBL-UTI.A retrospective study involving adult patients with UTI ESBL-producing organisms was undertaken. Patients non-ESBL-producing represented control group.In total, 1100 isolates were included study, 277 which ESBL positive. The rate 25.2%. mean age...
The emergence of antimicrobial resistance (AMR), particularly methicillin-resistant Staphylococcus aureus (MRSA), poses a significant global health threat as these bacteria increasingly become resistant to the most available therapeutic options. Thus, developing an efficient approach rapidly screen MRSA directly from clinical specimens has vital. In this study, we establish closed-tube loop-mediated isothermal amplification (LAMP) method incorporating hydroxy-naphthol blue (HNB) colorimetric...
Corynebacterium kroppenstedtii complex (CKC), including C. kroppenstedtii, parakroppenstedtii, and pseudokroppenstedtii, has been implicated in breast abscesses granulomatous mastitis, presenting diagnostic therapeutic challenges. Its lipophilic nature association with specific populations necessitate targeted investigations. This retrospective study was conducted at Hamad Medical Corporation, Qatar, all CKC isolates from tissue collected between October 2016 March 2024. Data electronic...
ABSTRACT A fatal case of primary amebic meningoencephalitis (PAM) in a 5-month-old infant is described. The disease may have been contracted during bathing. source water was from an artificial well. clinical presentation, the isolation ameba cerebrospinal fluid, poor response to amphotericin B, and ultimate outcome are all consistent with diagnosis PAM. On basis its ability grow at temperatures above 30°C, morphology trophozoite, presence flagellate forms, identified as Naegleria fowleri ....
Background: This large-scale cluster-randomised controlled trial (cRCT) evaluated use of facemasks against laboratory-confirmed viral respiratory tract infections (vRTIs) and clinical infection (CRI) because previous studies have been inconclusive. Methods: An open label cRCT, conducted in Makkah compared the offer 50 surgical worn over five days versus no among pilgrims. Cluster-randomisation was by accommodation tents stratified country gender. Tents were allocated to groups coin-tossing....
Geohelminth infections are a major problem of children from the developing countries. Children with these suffer developmental impairments and other serious illnesses. This study aimed to measure prevalence geohelminth infection, infection intensity as well change in Western Nepal over years. 6-year hospital based prospective at Manipal Teaching Hospital, Pokhara included (< 15 years) visiting Kaski 7 surrounding districts. Samples were also collected community different medical camps. Three...
Introduction: The diagnosis of urinary tract infections includes microbiologic culture urine to determine the etiology infection. However, interpretation results can be confounded by various factors including accuracy a patient's history current antibiotic usage. Methodology: In this report, we tested specimens for presence antibiotics and compared our data entry on accompanying request forms. addition, consequences culturing with incomplete received in laboratory were investigated. Results:...
Common organisms associated with community-acquired pneumonia include Streptococcus pneumoniae, Haemophilus influenzae, and Staphylococcus aureus. Pneumonia can rarely be caused by an organism such as cristatus, in our case. This belongs to the Mitis group within genus typically coexists humans oral cavity. We present a case of cristatus bacteremia community acquired previously healthy 40-year-old male, for whom infective endocarditis has been ruled out, who was successfully treated...
We describe an unusual case of actinomycosis that appeared as a nasal mass. The diagnosis was established when Actinomyces viscosus isolated from pus obtained the right maxillary antrum by intranasal antrostomy. patient treated with intravenous crystalline penicillin and made uneventful recovery within 10 days.
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...
Streptococcus gallolyticus is a gram-positive coccus belonging to the family bovis/Streptococcus equinus complex (SBSEC). Most cases of SBSEC bacteremia are reported in elderly males with underlying hepatobiliary disease and associated infective endocarditis (IE) or colonic malignancy. The gastrointestinal tract most common portal entry, followed by urinary tree. We present 5 intrapartum caused S. subsp from labor unit our hospital 2019 2021. There was histopathological microbiological...
