Background: The DES-obstructive sleep apnea (DES-OSA) score uses morphological characteristics to predict the presence and severity of obstructive sleep apnea syndrome (OSAS).

Objectives: To validate DES-OSA scores on the Israeli population. To identify patients requiring treatment for OSAS. To evaluate whether additional parameters could improve the diagnostic value of DES-OSA scores.

Methods: We performed a prospective cohort study on patients attending a sleep clinic. Polysomnography results were examined independently by two physicians. DES-OSA scores were calculated. STOP and Epworth questionnaires were administered, and data on cardiovascular risk was extracted.

Results: We recruited 106 patients, median age 64 years, 58% male. DES-OSA scores were positively correlated with apnea-hypopnea index (AHI) (P < 0.001) and were significantly different between the OSAS severity groups. Interobserver agreement for calculating DES-OSA was very high between the two physicians (intraclass correlation coefficient 0.86). DES-OSA scores ≤ 5 were associated with high sensitivity and low specificity (0.90 and 0.27, respectively) for moderate to severe OSAS. In univariate analysis, only age was significantly correlated with the presence of OSAS (OR 1.26, P = 0.01). Age older than 66 years as a single point in the DES-OSA score slightly improved the sensitivity of the test.

Conclusions: DES-OSA is a valid score based solely on physical examination, which may be useful for excluding OSAS requiring therapy. DES-OSA score ≤ 5 effectively ruled out moderate to severe OSAS. Age older than 66 years as an extra point improved the sensitivity of the test.

Background: C-reactive protein (CRP) blood level is associated with clinical outcomes of several diseases. However, the independent predictive role of CRP in the heterogeneous population of patients admitted to internal medicine wards is not known. 

Objectives: To determine whether single CRP levels at admission independently predicts clinical outcome and flow of patients in general medicine wards.

Methods: This study comprised 275 patients (50.5% female) with a mean age of 68.25 ± 17.0 years, hospitalized with acute disease in a general internal medicine ward. The association between admission CRP levels and clinical outcomes including mortality, the need for mechanical ventilation, duration of hospitalization, and re-admission within 6 months was determined.

Results: A significant association was found between CRP increments of 80 mg/L and risk for the major clinical outcomes measured. The mortality odds ratio (OR) was 1.89 (95% confidence interval (95%CI, 1.37–2.61, P < 0.001), mechanical ventilation OR 1.67 (95%CI, 1.10–2.34, P = 0.006), re-admission within 6 months OR 2.29 (95%CI, 1.66–3.15 P < 0.001), and prolonged hospitalization >7 days OR 2.09 (95%CI, 1.59–2.74, P < 0.001). Lower increments of10 mg/L in CRP levels were associated with these outcomes although with lower ORs. Using a stepwise regression model for admission CRP levels resulted in area under the receiver operating characteristics curves between 0.70 and 0.76 for these outcomes.

Conclusions: A single admission CRP blood level is independently associated with major parameters of clinical outcomes in acute care patients hospitalized in internal medicine wards.

Background: Diarrhea is a leading cause of child mortality worldwide. Rotavirus is one of the most common causes of severe diarrhea and dehydration in children.

Objectives: To compare the demographic, clinical and laboratory characteristics of patients with rotavirus gastroenteritis to those with other causes of gastroenteritis.

Methods: The medical records of children aged 0–18 years hospitalized with acute gastroenteritis in our facility between 1 January 2004 and 31 March 2006 were retrieved. Patients with rotavirus gastroenteritis were compared with patients who were rotavirus negative.

Results: The study group comprised 533 patients; 202 tested positive for rotavirus and 331 tested negative. Compared to patients with rotavirus-negative gastroenteritis, patients with rotavirus-positive gastroenteritis had a higher incidence of vomiting (185/202 vs. 212/331, 92% vs.  64%, P < 0.001), lethargy (67 vs. 51, 33% vs. 15%, P < 0.001), and dehydration (81 vs. 78 vs. 40% vs. 24%, P < 0.001). The need for intravenous rehydration therapy and the duration of hospitalization were higher in patients with rotavirus gastroenteritis.

Conclusions: Vomiting and dehydration are more common in hospitalized children with rotavirus gastroenteritis than in children with gastroenteritis due to other causes.
