The prevalence and significance of sleep-disordered breathing (SDB) in dialysis-independent chronic renal failure (CRF) remains unknown. We studied the presence of SDB in nondialyzed CRF patients. Diagnostic polysomnography was performed in consecutive stable nondialyzed CRF patients. Inclusion criteria were age 70% pr, absence of neurologic disease or hypothyroidism, and calculated creatinine clearance <40 ml/min. Thirty-five patients (19 male, 16 female) were studied. An apnea-hypopnea index (AHI) >or=5/h was present in 54.3% (almost exclusively obstructive events). AHI correlated with urea (r = 0.35, p = 0.037), age (r = 0.379, p = 0.025), and body mass index (BMI) (r = 0.351, p = 0.038), but not with creatinine clearance. AHI or SDB were unrelated to gender. In nondiabetics (n = 25), AHI correlated with urea (r = 0.608, p = 0.001) and creatinine clearance (r = -0.50, p = 0.012). Nondiabetics with severe CRF (calculated GFR < 15 ml/min/1.73 m(2)) had a significantly higher AHI compared with less severe CRF. Restless legs syndrome (RLS) was present in 37.1% and periodic limb movements in 28.6%. Daytime sleepiness was not associated with respiratory events, but was more common in patients with RLS. The prevalence of SDB and RLS is high in dialysis-independent CRF. SDB weakly correlates with indices of kidney function and this association becomes stronger in nondiabetics.
Respiratory manifestations of near-drowning in adult immersion victims are often severe. Nevertheless, in noncomatose patients at least, intubation can often be avoided and quick improvement is the rule while a good outcome is usually expected even in elderly patients.
The median +/- SD HA levels (pg/ml) in pleural fluid of patients with complicated effusions (39.058 +/- 11.208) were significantly increased (p < 0.005), compared to those with uncomplicated parapneumonic effusions (11.230 +/- 1.969), malignant effusions (10.837 +/- 4.803) or congestive heart failure (5.392 +/- 3.133). There was no correlation between pleural fluid and serum HA values. Pleural fluid TNF-alpha levels (146 +/- 127 pg/mL) and IL-1beta levels (133.4 +/- 156 pg/mL) were significantly higher in patients with complicated parapneumonic effusions compared to patients with other types of effusion (p < 0.05). No significant association between HA and TNF-alpha or IL-1beta was found. CONCLUSIONS. HA may play a significant role in the inflammatory process which characterises exudative infectious pleuritis. Further investigation might reveal whether HA is a useful marker in the management of parapneumonic effusions.
We present a case of drug- induced pneumonitis caused by carvedilol. Forty days after drug cessation, there was almost complete resolution of pulmonary infiltrates. This is the first report of pneumonitis caused by carvedilol.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
