Haemophilus influenzae, Streptococcus pyogenes, Moraxella catarrhalis, Staphylococcus aureus, and Streptococcus pneumoniae are usual cause of upper respiratory tract infection cases. The present study aims the isolation of bacterial strains which are resistant to the commonly prescribed antibiotics. In total, 900 throat swabs were obtained from the patients suffering from upper respiratory tract infections residing in three different localities. The maximum number of isolates (64 %) were obtained from locality-1 (L-1), whereas lowest isolates were found in second locality (L-2)...

Tofacitinib is an oral immunosuppressant approved for the treatment of rheumatoid arthritis (RA) and is currently undergoing investigation (Phase III trials) for treating chronic plaque psoriasis. Tofacitinib inhibits Janus kinases (JAKs), which are essential for the signaling of multiple inflammatory pathways and have been implicated in the pathogenesis of RA and psoriasis. The efficacy and safety of tofacitinib in the treatment of RA and psoriasis have been demonstrated in Phase III trials. Across all studies, the efficacy of tofacitinib in alleviating symptoms of RA and psoriasis were superior to placebo...

Acinetobacter baumannii is an important pathogen that causes nosocomial infections generally associated with high mortality and morbidity in Intensive Care Units (ICUs). Currently, little is known about the Quorum Sensing (QS)/Quorum Quenching (QQ) systems of this pathogen. We analyzed these mechanisms in seven clinical isolates of A. baumannii. Microarray analysis of one of these clinical isolates, Ab1 (A. baumannii ST-2_clon_2010), previously cultured in the presence of 3-oxo-C12-HSL (a QS signalling molecule) revealed a putative QQ enzyme (α/ß hydrolase gene, AidA)...

Pseudoaneurysms of the cervical internal carotid artery are rare and usually result from trauma, infection, or rarely spontaneously. They harbor potential risk of life-threatening hemorrhage and warrant immediate management. Endovascular treatment in the form of stent placement and coiling is a well established technique for dealing with both intracranial and extracranial pseudoaneurysms. We present a case of a child who presented with fever, neck swelling, dysphagia, and respiratory distress in emergency for which clinical diagnosis of a neck abscess was made...

A 24-year-old woman with history of asthma was intubated emergently for acute status asthmaticus triggered by acute respiratory syncytial virus infection and treated with permissive hypercapnia. Her ventilation was complicated by auto-positive end-expiratory pressure and elevated peak airway, plateau, and central venous pressures. On hospital day 2, she was noted to have anisocoria. Imaging showed diffuse cerebral edema with central herniation. Difficult ventilation and hypercapnia directly contributed to her severe cerebral edema...

Bronchospasm appears in up to 4% of patients with obstructive lung disease or respiratory infection undergoing general anesthesia. Clinical examination alone may miss bronchospasm. As a consequence, subsequent (mis)treatment and ventilator settings could lead to pulmonary hyperinflation, hypoxia, hypercapnia, hypotension, patient-ventilator asynchrony, volutrauma, or barotrauma. Electrical impedance tomography (EIT), a new noninvasive technique, can potentially identify bronchospasms by determining regional expiratory time constants (τ) for each one of the pixels of a functional EIT image...

BACKGROUND: Pneumonia is a leading cause of childhood mortality in a low resource country. Simple laboratory markers can help differentiate between bacterial and non-bacterial pneumonias for appropriate management. METHODS: In children aged one to 60 months with features of lower respiratory infection, C-reactive protein (CRP) and neutrophil-lymphocyte ratio (NLR) were used to differentiate between bacterial and non-bacterial pneumonias. The cutoff values for detecting bacterial pneumonias were evaluated by statistical tools...

Cell surface mucin (cs-mucin) glycoproteins are constitutively expressed at the surface of respiratory epithelia where pathogens such as influenza A virus (IAV) gain entry into cells. Different members of the cs-mucin family each express a large and heavily glycosylated extracellular domain that towers above other receptors on the epithelial cell surface, a transmembrane domain that enables shedding of the extracellular domain, and a cytoplasmic tail capable of triggering signaling cascades. We hypothesized that IAV can interact with the terminal sialic acids presented on the extracellular domain of cs-mucins, resulting in modulation of infection efficiency...

While complex intra- and interspecies microbial community dynamics are apparent during chronic infections and likely alter patient health outcomes, our understanding of these interactions is currently limited. For example, Pseudomonas aeruginosa and Staphylococcus aureus are often found to coinfect the lungs of patients with cystic fibrosis (CF), yet these organisms compete under laboratory conditions. Recent observations that coinfection correlates with decreased health outcomes necessitate we develop a greater understanding of these interbacterial interactions...

A young patient from central Africa presented acute renal insufficiency due to extrinsic compression of the distal ureters by a pelvic mass. After initial medical management, a biopsy revealed poorly differentiated bladder cancer and Schistosoma haematobium eggs embedded in the bladder wall. The initial workup showed evidence of locoregional disease. Radical cystectomy with an incontinent urinary diversion was performed with no complications. Carcinosarcoma of the bladder was diagnosed by pathological analysis of the surgical specimen...

REVIEW
Brian C Shook, Kai Lin
Respiratory syncytial virus (RSV) infection presents a significant health challenge in small children, the elderly and immunocompromised patients. There is still a high unmet medical need among patients with RSV infection, and no specific antiviral therapy is available. The only approved agents are palivizumab, which has to be given prophylactically, mainly in high-risk infants, and ribavirin, which is rarely used due to toxicity concerns and questionable benefits. Efforts to develop new antiviral agents have been hampered by the perceived need for high safety hurdles in pediatric patient populations use and the lack of well-characterized druggable targets...
