Purpose
Hyponatremia is a common electrolyte disorder in hospitalized patients. Clinical features, outcome and cost of hyponatremia-associated admission and hospitalization in elderly and very elderly patients are not well known.Methods
Elderly (>64 years) patients admitted to the emergency department (ED) and hospitalized between January 1, 2010, and December 31, 2010, were evaluated. Hyponatremia was defined as serum sodium level below 135 mmol/L. Hyponatremic patients were divided into two groups: group 1 (n = 150, 65–74 years old) and group 2 (n = 103, >74 years old).Results
A total of 4,960 patients above 65 years of age admitted to ED and hospitalized were included. Prevalence of ED in group 1 and group 2 was 4.1 % (150/3,651) and 7.8 % (103/1,309), respectively (p < 0.001). Vomiting and diarrhea were the most important complaints. A total of 111 (43.8 %) patients were being treated with renin–angiotensin system (RAS) blockers. Mortality, morbidity and hospital cost increased in parallel to decrease in serum Na+ level and increase in age. Group 2 subjects had not only higher intensive care need (p < 0.01) and mortality rates (p < 0.01), but also higher hospital cost burden (p < 0.05) compared to group 1. Alzheimer’s disease was one of the most common co-morbidity in patients, particularly in group 2 (5.3 % vs. 21.3 %, p < 0.001).Conclusion
Hyponatremia-associated hospitalization is an important and potentially lethal condition in elderly and very elderly patients. Clinicians should be careful when prescribing RAS blockers and diuretics in elderly patients. 相似文献4.
Attenuation of Ethanol Withdrawal by Ceftriaxone-Induced Upregulation of Glutamate Transporter EAAT2

Alcohol withdrawal syndrome (AWS) is a potentially fatal outcome of severe alcohol dependence that presents a significant challenge to treatment. Although AWS is thought to be driven by a hyperglutamatergic brain state, benzodiazepines, which target the GABAergic system, comprise the first line of treatment for AWS. Using a rat model of ethanol withdrawal, we tested whether ceftriaxone, a β-lactam antibiotic known to increase the expression and activity of glutamate uptake transporter EAAT2, reduces the occurrence or severity of ethanol withdrawal manifestations. After a 2-week period of habituation to ethanol in two-bottle choice, alcohol-preferring (P) and Wistar rats received ethanol (4.0 g/kg) every 6 h for 3–5 consecutive days via gavage. Rats were then deprived of ethanol for 48 h during which time they received ceftriaxone (50 or 100 mg/kg, IP) or saline twice a day starting 12 h after the last ethanol administration. Withdrawal manifestations were captured by continuous video recording and coded. The evolution of ethanol withdrawal was markedly different for P rats vs Wistar rats, with withdrawal manifestations occurring >12 h later in P rats than in Wistar rats. Ceftriaxone 100 mg/kg per injection twice per day (200 mg/kg/day) reduced or abolished all manifestations of ethanol withdrawal in both rat variants and prevented withdrawal-induced escalation of alcohol intake. Finally, ceftriaxone treatment was associated with lasting upregulation of ethanol withdrawal-induced downregulation of EAAT2 in the striatum. Our data support the role of ceftriaxone in alleviating alcohol withdrawal and open a novel pharmacologic avenue that requires clinical evaluation in patients with AWS. 相似文献

We evaluated 91 episodes of fever in 46 profoundly neutropenic children with cancer, in a search for any symptom, sign or laboratory test that would serve to identify patients with septicemia and differentiate them from those in no immediate need of prompt antimicrobial therapy. Seventeen episodes (19%) were bacteremias, 59 (64%) were suspected septic infections, 9 (10%) were focal bacterial infections and 6 (7%) proved not to be bacterial infections. We were unable to detect any parameter, either on admission or after two days of antimicrobial therapy (except for blood culture findings), that would be helpful in differentiating bacteremia from an episode not of bacterial origin. We focused on serum levels of C reactive protein and found them unreliable on an individual level. Prompt institution of antimicrobial therapy at the occurrence of fever results in low mortality, but does not allow assignment of cases to different categories. 相似文献

Analysis of premature ejaculation in hemodialysis patients using the International Index of Erectile Function 总被引:1,自引:0,他引:1
OBJECTIVE: We have conducted the following study to determine the prevalence of premature ejaculation in male hemodialysis patients and its impact on sexual quality of life. METHODS: This study was performed in hemodialysis facilities. Patients were asked to complete the International Index of Erectile Function (IIEF) questionnaire and also to report their ejaculation status. 98 male hemodialysis patients with normal potency were included in the study. The IIEF domain scores were determined, and the overall and relationship satisfaction rates were calculated for the patients with and without premature ejaculation separately. RESULTS: The mean age was 45.9 (range 30-69) years and the duration of hemodialysis was 37.8 (range 7-84) months. Premature ejaculation was determined in 31 (31.6%) patients. Patients with premature ejaculation experienced significantly lower overall satisfaction scores. Items of satisfaction with overall sexual life and sexual relationship with partner were responded to with a score of 'moderately satisfied' or 'very satisfied' in 47 and 53% of patients with premature ejaculation and 84 and 86% of patients without premature ejaculation, respectively. CONCLUSIONS: Premature ejaculation is a prevalent disorder in hemodialysis patients and seems to affect the satisfaction rate and sexual quality of life of these patients. 相似文献

OBJECTIVE: To determine the rate, risk factors and outcome of Tuberculous Peritonitis (TBP) in patients treated with continuous ambulatory peritoneal dialysis (CAPD) in our units. DESIGN: Retrospectively, we reviewed the medical data of all CAPD patients from 12 centers for TBP, covering the period between 1986 and December 2002. SETTING: All patients were from 12 renal clinics at tertiary-care university hospitals. RESULTS: Ten cases of TBP were identified among the CAPD patients in our centers. There were five male and five female patients with a mean age of 37.2 years. None of the patients had tuberculosis history, 6 patients had predominance of PNL. One patient had coincidental bacterial peritonitis. Two patients were successfully treated without the removal of the Tenckhoff catheter. CONCLUSION: TBP in CAPD patients is a very rare complication. In contrast to predominance of lymphocytes in nonuremic patients with tuberculous peritonitis, CAPD patients with tuberculous peritonitis may have predominance of PNL on examination of the peritoneal fluid. Since TBP has high morbidity and mortality, early diagnosis and treatment of disease are extremely important for improving outcome. 相似文献

Expression of CD44 and major histocompatibility complex class II antigens correlate with renal scarring in primary and systemic renal diseases 总被引:1,自引:0,他引:1

OBJECTIVE: Phenotypical changes in the tubular epithelial cells (TEC) seem to be important in the progression of renal diseases. The present study was designed to identify the relation between the expression of major histocompatibility complex (MHC) class II antigens and CD44 by TEC, with parameters of renal scarring in primary and systemic renal diseases. MATERIAL AND METHODS: Expression of MHC class II and CD44 antigens was determined immunohistochemically in 71 renal biopsies and eight nephrectomy specimens with chronic pyelonephritis (CP). RESULTS: CD44 expression was increased in renal diseases compared with autopsy cases and was strongly correlated with parameters of renal scarring and MHC class II antigen expression in primary and systemic renal diseases. CD44 expression was demonstrated in chronic pyelonephritis, postinfectious glomerulonephritis, diabetic nephropathy and hypertensive nephropathy, as well as other diseases described previously. Similar results were obtained for MHC class II antigen expression by TEC and these results were correlated with serum creatinine values. CONCLUSIONS: CD44 expression by TEC is a common pathway in renal scarring, like MHC class II antigen expression, and both of these may be important in renal scarring in CP cases as well as other primary and systemic renal diseases. 相似文献

ABSTRACT. Aperia, A., Broberger, B., Klinder, G., Herin, P. and Zetterström, R. (Department of Paediatrics, Karolinska Institute, St. Göran's Children's Hospital, Stockholm and Huddinge Hospital, Huddinge, Sweden). Postnatal deveopment of renal function in preterm and full-term infants. Acta Paediatr Scand, 70:183, 1981. –This study has been designed to examine the effect of gestational age (GA) on the postnatal development of renal function and has been performed in pre-term (PT) infants (GA=30–34 weeks) and in full-term (FT) infants (GA=39–41 weeks). Postnatal age has ranged from 1–35 days. From 8 hour urine samples collected after spontaneous voiding and a capillary blood sample, determinations have been made of the clearance of creatinine (CCr), the fractional excretion of β2-microglobulin (FEβ2) and the fractional excretion of sodium (FENa). In some infants receiving fluid parenterally, simultaneous determinations were made of the clearance of creatinine and inulin. As judged from this study, CCr is a reliable indicator of the glomerular filtration rate (GFR). GFR was almost the same in newborn PT and FT, but from 0.3–1 week of age GFR increased significantly more rapidly in FT than in PT. From 1–5 weeks of age GFR increased at approximately the same rate in PT and FT infants. The absolute value for GFR in 3–5 weeks old infants was lower in PT than in FT. FEβ2 was higher in PT than in FT infants during the entire first month of life and FENa was higher in PT than in FT infants during the first week of life, suggesting a glomerular tubular imbalance at least at the level of the proximal tubule in PT infants. It is concluded that different stages of maturation will alter the preconditions for the renal adaptation to extrauterine life during at least the first month of life. Therefore special attention must be paid to the limited renal function in PT during their entire first month of life. 相似文献
