Piperacillin/tazobactam-induced neurotoxicity in a hemodialysis patient: a case report

Antibiotics are potentially a cause of neurotoxicity in dialysis patients, the most common are thebeta-lactams as ceftazidime and cefepime, and few cases have been reported after piperacillin/tazobactam use. This report presents a case of a hypertensive and diabetic 67-year-old woman inregular hemodialysis, which previously had a stroke. She was hospitalized presenting pneumonia,which was initially treated with cefepime. Two days after treatment, she presented dysarthria, lefthemiparesis, ataxia, and IX and X cranial nerves paresis. Computed tomography showed no acutelesions and cefepime neurotoxicity was hypothesized, and the antibiotic was replaced bypiperacillin/tazobactam. The neurologic signs disappeared; however, 4 days after with piperacillin/tazobactam treatment, the neurological manifestations returned. A new computed tomographyshowed no new lesions, and the second antibiotic regimen withdrawn. After two hemodialysissessions, the patient completely recovered from neurological manifestations. The patient presentedsequentially neurotoxicity caused by two beta-lactams antibiotics. This report meant to alertclinicians that these antibiotics have dangerous neurological effects in chronic kidney diseasepatients.

Infecção do trato urinário adquirida em ambiente hospitalar em idosos

Introduction: Hospital-acquired urinary tract infection (HAUTI) is an important cause of morbidity in the elderly population. Objective: Evaluate the occurrence of HAUTI and risk factors associated with it. Method: This is a prospective study of a sample of 332 elderly people, interned in a university hospital. Criteria for defining infection were established by the Center for Diseases and Prevention Control. Statistical analysis of data used calculation of frequencies, odds ratio and logistic regression. The rate of hospital infection was 23.6%. The prevalent topographies of infection were respiratory infections (27.6%), urinary tract infections (26.4%) and surgical wound infections (23.6%, with 21, 20 and 19 episodes, respectively. The HAUTI incidence density associated with urinary catheterization was 24.2 infections by 1,000 catheter-days. The length of hospital stay of patients without nosocomial infection was 6.9 days and with HAUTI was increased in 10.4 (p<0.05).The rate of mortality of patients with HAUTI was 20%. Pathogens were isolated in 75% of episodes of HAUTI and the prevalent were: Escherichia coli (33%) and Pseudomonas aeruginosa (20%). Risk factors found for HAUTI were urinary catheterization implementation (odds ratio (OR) = 43.1; 95% confidence interval (95 CI%) = 3.9 – 311.1), hospitalization with community infection (OR= 21.9; 95% CI = 4.9 – 97.9); vascular diseases (OR=14; 95% CI = 2 – 98); diabetes mellitus (OR= 5.5; 95% CI = 1.4 – 21) and urinary catheterization by more than three days (OR=3.7; 95% CI = 1 – 13.8). Conclusions: HAUTI presented elevated incidence and it increased the length of hospital stay.

Sitios Assistenciais em Unidade de Terapia Intensiva e Relação do Nursing Activities Score com a Infecção Hospitalar

The Patient Classification System has become essential concerning to the practice in management and care from a nurse. This study analyzed the implementation of Assistance Sites in an intensive care unit for adults as a way of organization and classification of patients, as well as the impact of this process on the quality of care according to the Nursing Activities Score and the relation with the Hospital Infection. This is a quantitative, prospective, descriptive and transversal study. The data collection was realized from July until October 2010. The sample was consisted of 214 patients, mostly male, neurosurgical and with a mid age of 57 years. The NAS was on the average of 71.72%. Regarding the Hospital Infection before and after implantation, there was a reduction in the rates of pneumonia. However, the nursing workload remained the same. Moreover, It was evident the importance of using the Nursing Activities Score and the implementation of new ways for classification of patients to improve the organization of the care.

EC30-39 Swine Sanitation

From the very beginning of Nebraska's agricultural development its farmers have recognized that the production of swine must of necessity accompany the growing of corn. The latter, one of the state's most important staples, cannot be marketed in a more economical manner than after having been transformed into pork, bacon, and lard. As a result the state has for many years maintained a rather dense swine population mainly divided into large herds kept on relatively small areas of land. This density of population, as well as certain practices in management and selective breeding, has brought about conditions favorable for the propagation of a number of microbic or parasitic diseases which, in a costly manner, force themselves to our attention. The various factors which affect the incidence of swine diseases are numerous and in a given situtation may be so intricately interwoven as to baffle the observer. This extension circular discusses these factors and how to prevent the spread throughout the swine population.

Seroprevalence of equine influenza virus in northeast and southern Mexico

EQUINE influenza A virus (EIV) is a highly infectious respiratory pathogen of horses (Hannant and Mumford 1996, Palese and Shaw 2007). The illness is characterized by an abrupt onset of fever, depression, coughing and nasal discharge, and is often complicated by secondary bacterial infections that can lead to pneumonia and death. Two subtypes of EIV, H3N8 and H7N7, have been isolated. The H7N7 subtype was first isolated from a horse in Czechoslovakia in 1956 (Prague/56), and the H3N8 subtype was first isolated from a horse in Miami in 1963 (Sovinova and others 1958, Waddell and others 1963). The last confirmed outbreak of H7N7 occurred in 1979, and this subtype is now considered to be either extinct or circulating at low levels in a few geographical areas (Ismail and others 1990, Webster 1993, Singh 1994, Madic and others 1996, van Maanen and Cullinane 2002). The H3N8 subtype is a common cause of disease in horses worldwide, particularly in areas where vaccination is not routinely performed (Paillot and others 2006).

Antibodies to Influenza and West Nile Viruses in Horses in Mexico

INFLUENZA A virus (IAV) (family Orthomyxoviridae) is a highly infectious respiratory pathogen of birds and mammals, including human beings and horses (Palese and Shaw 2007). The virus is classified into different subtypes based on the antigenic properties of the haemagglutinin (HA) and neuraminidase (NA) proteins. Sixteen HA subtypes (H1 to H16) and nine NA subtypes (N1 to N9) have been identified (Fouchier and others 2005). Two subtypes, H3N8 and H7N7, have been isolated from horses. The H7N7 subtype was first isolated from a horse in Czechoslovakia in 1956 (Prague/56) (Sovinova and others 1958), and the H3N8 subtype was first isolated from a horse in Miami, USA, in 1963 (Waddell and others 1963). The H7N7 subtype has not been isolated from horses for three decades and is presumed to be extinct (Webster 1993). The H3N8 subtype is currently a common cause of disease in horses worldwide. In horses, influenza is characterized by an abrupt onset of pyrexia, depression, coughing and nasal discharge, and is often complicated by secondary bacteria infections that can lead to pneumonia and death (Hannant and Mumford 1996). Although H3N8 is a major cause of morbidity in horses throughout the world, information on the seroprevalence of IAV in horses and other domestic animals in Mexico is limited.
