introduction: arterial gas derangement could change urinary sodium excretion in chronic obstructive pulmonary disease (copd) patients.there are very few and conflicting data in regards to the measurement of fractional excretion of sodium in copd patients. the main aim of this study was to assess the relationship between renal fractional excretion of sodium(fena) with arterial blood gas and spir...

the clinical copd questionnaire (ccq) has been developed to measure the health status of copd patients. the aim of this study was to translate ccq into the persian language and assess the validity and reliability of the translated version. we used a forward-backward procedure to translate the questionnaire. in a cross-sectional study 100 copd patients and 50 healthy subjects over 40 years old w...

Forty-five patients with chronic obstructive pulmonary disease were studied to compare the acute effects of ipratropium bromide (60 µg), salbutamol (300 µg) and placebo (3 puffs) on the forced expiratory volume in 1 sec (FEV 1) and forced vital capacity (PVC). Ipratropium bromide produced a significantly greater improvement than salbutamol in both FEV1 and FVC at 15,60 and 180 minutes afte...

Primary or idiopathic retroperitoneal fibrosis, first described by Ormond in 1948, is a rare and elusive diagnosis, requiring a high level of suspicion. Patients usually present with entrapment of retroperitoneal organs, the most common being the ureters, causing hydronephrosis and acute kidney injury. Here, we present the case of a 56-year-old male presenting for recurrent and intermittent scr...

Lipocalin-type prostaglandin D synthase (L-PGDS), which is responsible for the biosynthesis of prostaglandin D2, has been reported to have a close connection with cardiovascular disease and sleep regulation. This study aimed to test the hypothesis that the L-PGDS level is a useful marker to identify patients with obstructive sleep apnoea. 64 subjects were enrolled in this prospective study. Uri...

OBJECTIVE To describe a systematic approach to finding the underlying cause of an elevated creatinine level. QUALITY OF EVIDENCE This diagnostic approach is based on a synthesis of information from reference works on nephrology, articles found through a MEDLINE search, and the author's personal experience. MAIN MESSAGE Elevated creatinine levels suggest the differential diagnosis of renal f...

The relation between exercise performance and certain measures of nutritional state was investigated in 83 patients with stable chronic obstructive lung disease (mean age 62 (8) years). All patients had a forced expiratory volume in one second (FEV1) less than 50% predicted, an arterial oxygen tension of more than 7.3 kPa, and no severe locomotor, cardiovascular, neurological, or endocrine diso...

Purpose: The present study is aimed to observe the differential response of pranayama in reducing high sensitivity C-reactive protein and creatinine kinase levels among chronic obstructive pulmonary disease patients comparison control patients.
 Material Methods: An intervention was done by enrolling 100 who were managed therapeutics. participants divided into non-intervention group with 5...

BACKGROUND Obstructive sleep apnea (OSA) is associated with hypertension and the progression of chronic kidney disease (CKD). Renal sympathetic innervation contributes to either condition. METHODS We investigated the effect of renal sympathetic denervation (RDN) on blood pressure (BP), renal perfusion, and neurohumoral responses during and after repetitive obstructive apneas in a pig model fo...
