RESUMO
Extraintestinal disease occurs in 5-8% of non-typhoid Salmonella enterica (NTS) infections and is more likely to be associated with hospitalization and death. The study examined the epidemiology of extraintestinal NTS infections in Israel and the possible effects of patients' age and sex. NTS isolates passively submitted to the National Salmonella Reference Center during 1996-2006 were the source for the study cohort. Poisson regression models were used to assess incidence trends over the study years and to evaluate the effects of patients' age and sex on the incidence of extraintestinal NTS manifestations. A total of 36,822 stool and 1,415 (3.7%) patient-unique NTS isolates from blood (74.1%), urine (18.3%), and other sources (3.7%) were studied. Serotypes Enteritidis, Virchow, and Typhimurium accounted for 66.3% of the isolates. Analysis showed a highly significant quadratic (U-shaped) relationship between patients' age and the incidence of extraintestinal isolation (p < 0.001), with increasing risk in the two extremes of age. Differences between the incidence of blood and urine sources were significant in patients <10 and >or=60 years old (relative risk [RR] = 5.88, 95% confidence interval [CI] 3.36-10.30, p < 0.001 and RR = 1.66, 95% CI 1.09-2.53, p = 0.017, respectively). Males >or=60 years of age were more likely than females of the same age to have bacteremia (RR = 1.90, 95% CI 1.39-2.61, p > 0.001) and less likely to have urinary NTS isolation (RR = 0.50, 95% CI 0.28-0.89, p = 0.018). Serotype Virchow had the highest incidence in patients <10 years of age, while serotype Enteritidis had the highest incidence in patients >or=60 years old. The study revealed a complex effect of patients' age and sex on the epidemiology of extraintestinal NTS manifestations.

Increased resistance among isolates causing bacteremia constitutes a major challenge to medical practitioners and institutions. Variability between institutes is substantial, and requires the individual analysis of local trends. An eight-year (1997-2004) surveillance study of episodes of bacteremia was conducted in an 850-bed university hospital in central Israel. Trends of incidence, resistance, age, and mortality were analyzed. We studied 6,096 patient-unique episodes of bacteremia, of which, 2,722 (45.3%) were nosocomial and 523 (9.2%) involved children less than 18 years of age. The overall incidence of bacteremia episodes has increased over the study years by 39% and the patient mean age by 7.5 years. Gram-negative organisms accounted for 72% of hospital-acquired cases and 69% of community-acquired cases. There was a substantial increase in the incidence of nosocomial episodes, predominantly due to Gram-negative isolates, mainly Acinetobacter baumannii, Klebsiella pneumoniae, and Escherichia coli. Increased resistance to broad-spectrum antibiotics was noted among Gram-negative organisms, including quinolones (in K. pneumoniae), imipenem (A. baumannii and P. aeruginosa), piperacillin-tazobactam (K. pneumoniae), and amikacin (A. baumannii and P. aeruginosa). Increased resistance to oxacillin among coagulase-negative staphylococci was also noted. The all-cause mortality rates showed a significant rise. The patient age, intensive care unit (ICU) stay, and hospital acquisition were independently associated with mortality. We describe an increase in the incidence and resistance of Gram-negative organisms causing bacteremia and concomitant ageing of the patients with bacteremia. Similar patterns have been reported from other localities, and are of real concern.

BACKGROUND: The objective was to assess the safety and efficacy of L-NMMA in the treatment of cardiogenic shock. METHODS: We enrolled 11 consecutive patients with cardiogenic shock that persisted after >24 hours from admission, despite coronary catheterization and primary percutaneous transluminal coronary revascularization, when feasible, and treatment with mechanical ventilation, intraaortic balloon pump (IABP), and high doses of catecholamines. L-NMMA was administered as an IV bolus of 1 mg/kg and continuous drip of 1 mg. kg(-1). h(-1) for 5 hours. Treatment with catecholamines, mechanical ventilation, and IABP was kept constant throughout the study. RESULTS: Within 10 minutes of L-NMMA administration, mean arterial blood pressure (MAP) increased from 76+/-9 to 109+/-22 mm Hg (+43%). Urine output increased within 5 hours from 63+/-25 to 156+/-63 cc/h (+148%). Cardiac index decreased during the steep increase in MAP from 2. 0+/-0.5 to 1.7+/-0.4 L/(min. m(2)) (-15%); however, it gradually increased to 1.85+/-0.4 L/(min. m(2)) after 5 hours. The heart rate and the wedge pressure remained stable. Twenty-four hours after L-NMMA discontinuation, MAP (+36%) and urine output (+189%) remained increased; however, cardiac index returned to pretreatment level. No adverse events were detected. Ten out of eleven patients could be weaned off mechanical ventilation and IABP. Eight patients were discharged from the coronary intensive care unit, and seven (64%) were alive at 1-month follow-up. CONCLUSIONS: L-NMMA administration in patients with cardiogenic shock is safe and has favorable clinical and hemodynamic effects.

Serum zinc levels and urinary zinc excretion were compared in 15 patients with essential hypertension taking chronically a combination of hydrochlorothiazide and amiloride as monotherapy, eight patients maintained with hydrochlorothiazide alone, and eight control subjects. Serum zinc values were statistically comparable in all three groups. However, urinary zinc excretion was abnormally elevated in the two patient groups. In the dosage used, amiloride did not have a zinc-sparing effect.

OBJECTIVE: To evaluate the safety and efficacy of low-dose dopamine, high-dose furosemide, and their combination in the treatment of refractory congestive heart failure. METHODS: Twenty consecutive patients with refractory congestive heart failure were randomized to receive intravenous low-dose (4 micrograms/kg/min) dopamine combined with low-dose (80 mg/day) oral furosemide (group A; n = 7), intravenous low-dose dopamine with medium-dose furosemide (5 mg/kg/day through continuous intravenous administration; group B; n = 7), or high-dose furosemide (10 mg/kg/day through continuous intravenous administration; group C; n = 6). RESULTS: The three groups showed similar improvement in signs and symptoms of congestive heart failure, urinary output (2506 +/- 671 ml/24 hr, mean +/- SD) and weight loss (3.3 +/- 2.3 kg) after 72 hours of therapy. Mean arterial blood pressure (MAP) decreased by 14% +/- 8% and 15% +/- 6% in groups B and C, respectively, but increased by 4% +/- 15% in group A (p = 0.017). Renal function deteriorated significantly in groups B and C: creatinine clearance decreased by 41% +/- 23% and 42% +/- 23%, respectively, but increased by 14% +/- 35% in group A (p = 0.0074). MAP decrease was positively correlated with the decrease in creatinine clearance (r = 0.7; p = 0.0007). Patients in group B and C had more hypokalemia than group A. Two patients in group C sustained acute oliguric renal failure and one patient in group B died suddenly while sustaining severe hypokalemia. CONCLUSION: Combined low-dose intravenous dopamine and oral furosemide have similar efficacy but induce less renal impairment and hypokalemia than higher doses of intravenous furosemide taken either alone or with low-dose dopamine. The renal impairment induced by intravenous furosemide is probably related to its hypotensive effect in patients with refractory congestive heart failure.

Sixty consecutive normotensive patients with unstable angina pectoris, who were on continuous intravenous isosorbide dinitrate (ISDN) treatment and had not previously received angiotensin II receptor antagonists, angiotensin-converting enzyme (ACE) inhibitors, or diuretics were randomly assigned to treatment groups receiving intravenous ISDN for 72 hours. No additional treatment was given to group A (n = 15). Captopril, in a test dose of 6.25 mg, and followed by 12.5 mg 3 times daily for 24 hours and 25 mg 3 times daily for the next 24 hours, was given to group B (n = 15). The same dose of captopril plus 40 mg of furosemide in the morning were given to group C (n = 15). Losartan, in a single dose of 25 mg/day and increased to 50 mg after 24 hours was given to group D (n = 15). Nitrate tolerance was evaluated at 24-hour intervals at trough levels of each of the drugs by administering intravenous ISDN (1 mg bolus dose every 4 minutes) and recording the total ISDN test dose required to decrease the mean arterial blood pressure by > or =10%. Treatment with continuous ISDN only (group A) induced nitrate tolerance. The ISDN (mean +/- SD) test dose was 3.5 +/- 1.8 mg at baseline, increasing to 4.9 +/- 2.4 mg at 24 hours, and 8.0 +/- 3.0 mg at 48 hours. The addition of increasing doses of captopril to the continuous ISDN treatment (group B) completely prevented nitrate tolerance. Losartan, however, did not attenuate nitrate tolerance at 24 hours and attenuated it only partially at 48 hours. The addition of furosemide to captopril had no further effect on nitrate tolerance. Of 15 patients in group A (ISDN only), 4 (27%) experienced recurrent ischemic events requiring urgent coronary catheterization. No such events were recorded in group B (captopril), but did occur in 1 patient in each of group C (captopril plus furosemide) and D (losartan) (p = 0.083). Thus, the addition of captopril to the ISDN treatment regimen prevented tolerance to nitrates and improved angina control with apparent safety. Losartan also decreased nitrate tolerance, although to a lesser extent, and also improved angina control. The addition of furosemide to captopril conferred no further benefit.

OBJECTIVE: To investigate erythrocyte membrane Na+, K(+)- and Ca2+, Mg(2+)-ATPase activities in newly diagnosed hypertensive patients before and after 2, 4, and 6 months of treatment with enalapril or captopril as monotherapy. METHODS AND RESULTS: Na+, K(+)-ATPase activity (nmol ATP hydrolysed/min per mg protein) rose by 6 months of treatment in both groups when values were compared in each treated group over time (4.5 +/- 0.8 to 9.9 +/- 1.2; 4.9 +/- 0.8 to 10.5 +/- 1.7, respectively, p < 0.001 for both). When the treated groups were compared with controls at each period of time, Na+, K(+)-ATPase activity was higher at months 4 and 6 (p < 0.001) for both groups, respectively). Ca2+, Mg(2+)-ATPase activity (nmol ATP hydrolyzed/min per milligram protein) in the absence and in the presence of calmodulin increased in the enalapril (6.4 +/- 0.7 to 8.9 +/- 0.95, p < 0.05; 13.4 +/- 1.2 to 17.2 +/- 1.2, p < 0.05, respectively) and captopril (7.0 +/- 0.6 to 8.5 +/- 0.7; 14.4 +/- 1.1 to 16.0 +/- 1.0, p < 0.05, respectively) groups after 6 months of treatment compared within each treated group over time. When patient groups were compared with controls at time 0, 2, 4, and 6 months, the pump activity was higher in the treated groups at 6 months. CONCLUSION: The long-term enhancement of cell membrane Na+, K(+)-and Ca2+, Mg(2+)-ATPase activity associated with enalapril and captopril therapy may represent a specific effect of these agents or alternatively, a nonspecific outcome of blood pressure reduction.

Complete atrioventricular block and syncope sometimes are the presenting signs of acute myocardial infarction. In a presyncopal attempt to assume sitting position, the patient may fall and suffer consequent trauma. Once in hospital, this sequence of events may be overlooked by both the patient and admitting physicians. Moreover, physical examination initially may not be revealing. We report on two such patients who developed massive subcutaneous bleeding following thrombolytic and heparin treatment. We conclude that these patients constitute a specific group with a relatively high risk of trauma and bleeding at the gluteal region following thrombolytic therapy. Special attention must be given to these patients.

Endocarditis is the most devastating complication of brucellosis. The accepted treatment for Brucella endocarditis (BE) is a combination of valve replacement and antibiotics. Conservative antibiotic treatment alone is not recommended by most authors, as it is considered ineffective, risking fatality. We describe a patient with BE, in whom antibiotic treatment alone resulted in complete recovery. On reviewing the literature, we found 12 additional such cases. We compared this group of 13 patients with data from 49 published cases treated with a combination of surgery and antibiotics, with a favorable outcome. Absence of congestive heart failure or a prosthetic valve, relatively mild extravalvular cardiac involvement, and a somewhat shorter disease history until initiation of treatment were characteristic of the group treated conservatively in comparison with patients who underwent surgery. In selected patients with BE, conservative antibiotic treatment may be a valid alternative to surgery.

Reports of chylothorax (CT) following median sternotomy are rare, amounting so far to 16 cases in the English literature, of which 6 were cases of postcoronary artery bypass grafting (CABG). This report deals with an additional case of a 70-year-old woman who developed left pleural chylous effusion following CABG. It is suggested that the incidence of this type of pleural effusion is considerably greater than the few cases hitherto reported. Moreover, as CT may produce serious pulmonary and/or pleural functional impairment, it is proposed that a diagnostic tap be performed more often in cases of post CABG pleural effusion and that preventive drainage be instituted when CT is diagnosed.

BACKGROUND: Magnesium depletion and hypomagnesemia are common among furosemide-treated patients with chronic congestive heart failure. HYPOTHESIS: This investigation evaluated clinical and metabolic effects of oral magnesium supplementation. METHODS: Ten patients with severe congestive heart failure maintained on high dose furosemide (> or = 80 mg/day) received a supplement of oral magnesium citrate 300 mg/daily for 30 days. Clinical parameters were followed, and peripheral blood mononuclear cell magnesium and zinc content, serum and urine magnesium, potassium, zinc, calcium, phosphorus, and creatinine were assessed. RESULTS: Peripheral blood mononuclear cell magnesium content and serum potassium rose significantly at the end of the study (2.09 +/- 1.89 to 3.99 +/- 2.26 micrograms/mg cell protein, p < 0.05, and 4.17 +/- 0.38 to 4.39 +/- 0.27 mEq/l, p < 0.05, respectively), while the other parameters remained unchanged. CONCLUSION: In some of these patients, oral magnesium supplementation is effective in achieving substantial increments in intracellular magnesium and serum potassium which, in turn, may have cardioprotective effects.

OBJECTIVE: The objective of this study was to assess the pharmacokinetics of intraperitoneal (IP) administration of the antibiotic combination piperacillin/tazobactam (PIP/TAZ) to patients on chronic ambulatory peritoneal dialysis (CAPD) with and without pseudomonas peritonitis. DESIGN: Open-labeled study. SETTING: The study was carried out in the CAPD unit of Assaf Harofeh Medical Center, Zerifin, Israel. PATIENTS AND METHODS: Six patients participated in the study, 4 had pseudomonas peritonitis, all were given an IP loading dose of 4 g/0.5 g PIP/TAZ. Twenty-four hours after the initial dose, a maintenance dose of 0.5 g/0.0625 g PIP/TAZ was administered with each dialysate exchange for a period of 1 week. The patients without peritonitis received only the loading dose. High performance liquid chromatography was used to determine the concentrations of PIPITAZ in plasma obtained at 0, 30, 60, 90, 120, 360, 480, 600, 720, and 1440 minutes after administration. Samples of the dialysate fluid for determination of PIP/TAZ concentration were collected at 6,10,14, 24, and 72, 120, and 168 hours. RESULTS: After the loading dose, the highest plasma PIP concentration (Cmax) was 51.6 t 21.25 Lig/mL and appeared at 1.5 = 0.45 hours (t,,a). During the maintenance period plasma PIP concentration was 5.2 t 4.75 Lg/mL. Tazobactam was detected in the plasma of 1 patient only. The concentration of TAZ in the dialysate fluid during the maintenance period was 2.3 t 0.5 ig/mL. CONCLUSIONS: Piperacillin administered IP at 4 g reached plasma concentrations comparable to intravenous administration and considered therapeutic (above the MIC90 for Pseudomonas aeruginosa) in CAPD patients with or without peritonitis. The maintenance dose, however, should be augmented. Tazobactam could not be detected in the plasma of most patients and the therapeutic implications of IP administration of TAZ cannot be directly correlated to intravenous administration.

A 41-year-old man with rheumatoid arthritis developed severe acute hepatitis 3 days after starting cimetidine for duodenal ulcer. Other causes were ruled out and he recovered after cimetidine was discontinued. Mild transient elevations of hepatic enzymes have been reported in 3.6% of patients taking cimetidine. However, only 12 cases of severe acute hepatitis associated with cimetidine, mostly secondary to idiosyncrasy, have been reported in the English literature. This rare but serious complication of cimetidine should be kept in mind.

Potassium is the most important intracellular cation in a humans body. Potassium gradient between the intracellular fluid to the extra cellular fluid is crucial for normal nerve-muscle activity. Hypokalemia is a frequent abnormality among patients, exposing them to fatigue and arrhythmia. Understanding the pathophysiology of hypokalemia may help the clinician to treat it properly. The approach to the patient with hypokalemia is presented through the description of a 25-year-old woman who was admitted to the department due to palpitation and hypokalemia. A simple primary investigation is suggested in these cases.

2 women with quinidine-induced lupus are presented. This condition is rare; only about 30 cases have been reported in the English literature. Both our patients had arthritis of the wrist, antinuclear antibodies with homogenous pattern and elevated ESR. Anti-double stranded DNA antibodies were present in 1 patient, and a petechial rash in the other. Complete resolution of arthritis occurred within a few days after quinidine withdrawal, but antinuclear antibodies persisted for several months.

A high prevalence of maternal group B Streptococcus (GBS) carriage and an extremely low incidence of invasive neonatal disease have been reported from southern Israel. In order to obtain insight into this discrepancy, this study was performed to determine the population structure of GBS from asymptomatic pregnant women living in this area. Seventy-two strains from maternal GBS carriers were characterized using multilocus sequence typing (MLST). Epidemiologic characteristics of the carriers and their newborns, including demographic variables, obstetric status, and general health parameters, were collected by means of a postpartum interview and a review of the relevant medical records. The MLST analysis grouped the bacteria into six different lineages (clonal complexes). Lineage ST-2 was prevalent among Bedouin-Arabs (p=0.01) and lineage ST-22 among Jews (p=0.001). Lineage ST-17 was prevalent among carriers who emigrated after 1997 from western nations of the former USSR (p<0.001). Lineage ST-22 was associated with carriage of surface-protein C (p=0.01) and lineage ST-17 with surface-protein R (p<0.01). Lineage ST-2 was prevalent among consumers of antibiotics (p=0.02) and was associated with erythromycin-resistant strains (p<0.001). Each subgroup of the southern Israeli maternal population has a different distribution of GBS clones. The clones prevalent among the Bedouin-Arabs and the Jews are known to be of low virulence. Lineage ST-17, which is associated with invasive disease, is prevalent among women who emigrated from western Soviet nations. Therefore, a different policy of GBS prophylaxis, resembling the one executed in endemic areas, should be considered in this population.
