Bordetella are small Gram-negative coccobacilli, of which Bordetella pertussis is the most important human pathogen. It is the cause of whooping cough, which is one of the 10 leading causes of childhood death. Transmission of this highly infectious organism is primarily by aerosolized droplets. Clinical features—presentation varies with age, immunization and previous infection: (1) infants—apnoea, cyanosis, and paroxysmal cough; (2) nonimmunized children—cough, increasing in severity with distressing, repeated, forceful expirations followed by a gasping inhalation (the ‘whoop’); (3) children immunized in infancy—whooping, vomiting, sputum production; (4) adults—cough, post-tussive vomiting. Atypical mild illness is common. Complications include pneumonia, pulmonary hypertension, seizures and encephalopathy. Most deaths occur in those less than 2 months old....

Whooping cough is a notifiable bacterial respiratory infection caused by Bordetella pertussis. It may produce serious disease, especially in immunocompromised individuals and very young children. The number of reported cases increases in the winter months and the incidence peaks every 4–5 years. However, this periodicity is variable and is inconsistent between different geographical regions. Bordetella pertussis infection (BPI) may be underdiagnosed because of its seasonality and the fact that clinical features may be indistinguishable from other respiratory disorders in the paediatric ED setting. Treatment with antibiotics reduces the period of infectivity but may not shorten the illness. This review discusses the epidemiology of the disease, its clinical features, diagnosis, treatment and the disposition of patients with BPI.

Background: Despite guidelines recommendations for early invasive management in non-ST-elevation myocardial infarction (NSTEMI), some patients (pts) with significant coronary artery disease (CAD) found on early angiography do not undergo revascularization. The prevalence, clinical features, and long-term prognosis of this population have not been well-characterized. Methods: We evaluated 8225 NSTEMI pts from the SYNERGY trial (2002–2004) with >50% stenosis in at least 1 epicardial artery who received in-hospital percutaneous coronary intervention (PCI), in-hospital coronary artery bypass grafting (CABG), or no revascularization before discharge (medical management). A propensity-adjusted Cox proportional hazards model was used to compare death/MI rates at 6 months and mortality rates at 1 year among the 3 subgroups starting from the time of hospital discharge. Results: A total of 2633 of 8255 pts (32%) were medically managed, 4294 (52%) underwent PCI, and 1298 (16%) underwent CABG. Clinical features and unadjusted outcomes are shown below. Guidelines-recommended discharge medications were used in a large proportion of patients, but those undergoing PCI most commonly received evidence-based therapies. The adjusted risk of 6-month death or MI was 2.19 (95% CI: 1.79–2.67) for medical management compared with PCI, and 3.07 (95% CI: 2.18 – 4.34) for medical management compared with CABG. The adjusted risks of 1-year mortality for medical management were 1.52 (95% CI: 1.07–2.17) and 1.70 (95% CI: 0.96–3.03), respectively. Conclusion: A substantial proportion of NSTEMI pts with significant CAD are managed medically without in-hospital revascularization. These pts have higher-risk clinical characteristics and worse outcomes compared with those who undergo PCI or CABG, despite fairly good use of evidence-based medications. Therefore, innovative treatment strategies are needed to mitigate the increased risk of adverse outcomes in this population.

Purpose. To evaluate the clinical features, microbiological spectrum, and treatment outcomes of endogenous endophthalmitis.Methods. Retrospective review of consecutive cases with infective endogenous endophthalmitis presenting from 2000 to 2007. The main outcome measure was the visual outcome at the latest follow-up visit. Other outcome measures included microbiological investigations, anatomical and clinical outcomes.Results. 22 eyes of 21 patients were included, and the mean follow-up duration was 2.7 years. Eyes with fungal endogenous endophthalmitis were more likely to have visual acuity of finger counting or better at presentation compared with those with bacterial endogenous endophthalmitis (odds , ). Gram-negative microorganisms accounted for 50% of infections, while fungal and gram-positive organisms accounted for 27.3% and 22.7%, respectively. Despite treatment, the visual outcome was poor in general as 10 (45.5%) eyes had no light perception at the latest follow-up visit and 6 (27.3%) eyes required enucleation or evisceration. Contrary to previous studies, fungal endogenous endophthalmitis did not appear to have better visual outcome compared with bacterial endogenous endophthalmitis.Conclusion. Gram-negative microorganisms were the main causative pathogens of endogenous endophthalmitis in Hong Kong. The visual prognosis of endogenous endophthalmitis is generally poor as almost 50% of eyes were blind despite treatment.

The clinical study was done in 60 cases of urolithiasis in randomized controlled pattern to evaluate the efficacy of Shigru (Moringa oleifera Lam) root decoction in medical management of urinary stone (Mutrashmari). The study was conducted at Department of Shalya Tantra, Government Ayurvedic College and Hospital, Nanded, Maharashtra. For assessment of result patients were investigated by USG & X-ray KUB. Clinical features like pain, burning micturition, haematuria and strangury were also used for analysis of result. Patient’s routine blood and urine examination were carried out. The study reveals that Shigru root decoction has significant role in the management of mild to moderate sized urolithiasis and also give immediate relief to associated features.
