nonencapsulated, nontypeable hemophilus influenzae (nthi) remains an important cause of acute otitis and respiratory diseases in children and adults. nthi bacteria are one of the major causes of respiratory tract infections, including acute otitis media, cystic fibrosis, and community-acquired pneumonia among children, especially in developing countries. the bacteria can also cause chronic dise...

conclusions the fev1/fev6 ratio can be used as a valid surrogate for fev1/fvc in the diagnosis of airway obstruction, especially for screening purposes in high-risk populations for copd. moreover, fev6 is an acceptable alternative for fvc in detection of restrictive pattern. results this study shows that the current cut-off points used to detect obstruction and restriction can be replaced by fe...

BACKGROUND Researchers have developed several equations to predict glomerular filtration rate (GFR) in patients with chronic kidney diseases (CKD). However, there are scarcely any studies performed to discern the best equation to estimate GFR in patients with pure obstructive nephropathy. In present study, we assessed the suitability of six prediction equations and compared their performance in...

BACKGROUND The present study sought to assess the renal and liver protective effect of N-acetylcysteine through NH3 and urea metabolism in patients with chronic obstructive pulmonary disease who were scheduled for coronary artery bypass grafting surgery. MATERIAL AND METHODS Patients with chronic obstructive pulmonary disease (COPD) who were scheduled for coronary artery bypass grafting were di...

chronic kidney disease (ckd) is a major public health problem that often goes unrecognized until late-stagedisease. patients with chronic kidney disease face with uremic toxins and hyperkalemia. also fluid overloadin ckd patients is associated with rapid decline in kidney function. lactulose is a hyper osmotic agent andas a prebiotic plays an important role in regulating serum urea and potassiu...

Retroperitoneal fibrosis or Ormand's disease is rare in incidence and clinically elusive to diagnosis until obstructive uropathy clinically manifests by the mechanism of ureteral fibrotic strangulation and acute renal failure. We encountered a 50-year-old woman with months of nonspecific abdominal pain and presented with signs and symptoms of acute renal failure. Laboratory data was significant...

INTRODUCTION Scores to predict surgical risk in patients submitted to myocardial revascularization surgery are broadly used. OBJECTIVE To develop a score capable to predict mortality in patients submitted to myocardial revascularization surgery. METHODS From January 1996 to December 2007, data were collected from 2809 patients submitted to myocardial revascularization surgery at PUC-RS São ...

background :chronic obstructive pulmonary disease (copd) is a third leading cause of death.   methods : in this case control study, we prepared 5 cc bloods from the antecubital vein of 100 copd patients and 40 healthy individuals as control group. vascular endothelial growth factor (vegf) expression protein level was measured by elisa in both groups.   results : we found that concentration of v...

Case presentation 1: A 78-year-old woman with a history of morbid obesity, coronary artery disease, chronic obstructive pulmonary disease, and chronic kidney disease (serum creatinine 2.0 mg/dL) presented to the emergency department with worsening dyspnea. Her ECG shows no acute ischemic changes; her chest radiograph reveals chronic emphysematous changes with mild bilateral infiltrates. Her lun...

abstract  background: despite the long-standing association of macrophage migration inhibitory  factor (mif) with delayed-type hypersensitivity response, the potential role  of mif in chronic allograft nephropathy is unknown. the association between upregulation of mif expression, macrophage and t cell infiltration and the severity of  chronic allograft nephropathy suggests that mif may be an i...
