Butyrylcholinesterase activity and plasma lipids in dexamethasone treated rats

The paper describes the effect of glucocorticoid dexamethasone (DM) given intraperitoneally on the catalytic activity of butyrylcholinesterase (BuChE) measured in plasma, liver and white adipose tissue of rats of both sexes. Effects of DM on the concentration of plasma lipids and lipoproteins were also tested. Rats were given multiple (2 and 4) pharmacological doses (0.4 and 3.0 mg kg(-1) body mass) of DM. All animals were sacrificed 48 hours after the last dose. Administration of DM significantly decreased the catalytic activity of BuChE in plasma and liver of all treated groups regardless of sex. BuChE catalytic activity in white adipose tissue differed depending on the dose and frequency of administration. In contrast to liver where both doses caused significant BuChE inhibition, the lower DM dose did not inhibit BuChE activity in adipose tissue, and the inhibition achieved by the higher dose was not as strong as in liver. This result corroborates an earlier hypothesis that BuChE is also synthesized in the adipose tissue. DM significantly increased plasma concentrations of triglycerides, total cholesterol and high-density lipoprotein (HDL) cholesterol and decreased the low-density lipoprotein (LDL) cholesterol concentration. Neither positive correlation between BuChE and triglycerides nor negative correlation between BuChE and HDL was found. Changes in lipid profile during DM treatment were not sex- and time-dependent.     

Pharmacists' knowledge of sanitary legislation and professional regulations

OBJECTIVE: To characterize the profile of pharmacists employed as technical supervisors in drugstores and evaluate their knowledge regarding certain aspects of the legislation controlling drugstores and the profession in general. METHODS: Based on 175 drugstores in the city of Ribeir?o Preto, southeastern Brazil, 100 pharmacists/technical supervisors were randomly selected. Data collection was done by means of in-person interviews, and was guided by a questionnaire evaluating knowledge and attitudes. Data were processed and analyzed using Epi Info and Stata software. Associations were sought between dependent and independent variables using Pearson's chi-squared and Fisher's exact tests. RESULTS: Most pharmacists were women (64%), aged 22-29 years (47%), graduated approximately three years prior to data collection, trained to work in the pharmaceutical industry (36%) or in clinical analysis (29%). Pharmacist's knowledge of sanitary legislation was considered as insufficient for 28% of subjects, regular for 50%, and good for 22%. Low levels of knowledge were observed regarding the legal requirement for the presence of a pharmacist during the entire drugstore opening hours, pharmacists' attributions, sale of antibiotics, and penicillin administration. It was found that most professionals have difficulties handling the concepts of 'generic' and 'similar' drugs. Low level of knowledge was not associated with any of the independent variables, indicating that this is a generalized phenomenon, i.e., one present among pharmacists of all age groups and both sexes, irrespective of the time since graduation, institution attended, and modality of graduation, among others. CONCLUSIONS: We conclude that training in the field of drug pharmaceutical care, during undergraduate studies and, especially, during traineeship in pharmacies and drugstores is deficient. It is necessary to divulge information concerning sanitary legislation so that pharmacists may fully exert their profession, without risk of legal threats or hazard to the population.     

Hypereosinophilic syndrome in a child presenting as eosinophilic pharyngitis

A 3-year-old child with idiopathic hypereosinophilic syndrome (IHES) presented with sore throat and pharyngeal exudate. Recurrent throat cultures were negative and microscopic section of the exudate revealed an extensive eosinophilic infiltration. Fourteen months later, the child still has marked hypereosinophilia and pharyngeal involvement without other organ involvement. Eosinophilic pharyngitis may be a target organ in IHES. The benign clinical course and the laboratory characteristics are described.     

The role of some micronutrients in the evolution of HPV infection

BACKGROUND: Over the past few years a series of research projects has shown that the scant or deficient immune response in HIV infection may be secondary to reduced cell resistance and/or the uncontrolled formation of free radicals. In line with these findings, subjects with HIV infection present a deficit of polyunsaturated fatty acids (the principal components of cell membranes) and many antioxidating substances, like Vitamin E and glutathione peroxidase. The high incidence of heterosexual transmission of HIV has now shown the close correlation between HIV infection and HPV infection. By analogy, we wanted to ascertain whether these deficits were also present in subjects with HPV infection and dysplastic and neoplastic lesions of the uterine cervix. Published data confirm that a HPV-positive subject has an increased risk, ranging from 40 to 200%, of contracting HIV infection. METHODS: Eighty women with HPV infection of the genital tract, at various stages. Blood levels of vitamin E and polyunsaturated fatty acids were measured using gas-chromatography; glutathione was assayed using the spectrophotometric technique. RESULTS: The alternation of the aforesaid parameters is correlated to the progress of infection and increases with the severity of lesions; Statistically significant data were recorded by comparing the group with condylomatosis with patients diagnosed with cervical carcinoma (p<0.001). CONCLUSIONS: The increased possibility that some patients are affected by an association of HPV and HIV depends on the anomalous or scarce function of many immunocompetent cells, as well the quantitative immune deficiency induced by the initial virus and the presence of various mechanisms that facilitate the development of the infection.     

Diet and coronary heart disease

Diet is important in the prevention and treatment of coronary heart disease. Nurses are key in providing and reinforcing consistent dietary messages as part of the multidisciplinary team.     

Surgical treatment of chronic suppurative otitis media

The results of surgical treatment of chronic suppurative otitis media with or without cholesteatoma were presented in 708 patients over the period of ten years. Microtoilet of the ear and treatment of pathologic processes in the upper respiratory tract in the preoperative period the authors consider important for success in surgery. The best functional results were achieved with tympanoplasty bearing in mind adjustment of operative technic for each case depending on the nature and spreading of the process. The most frequent recurrences occurred in patients with cholesteatoma surgery (32%).     

Interactions between foot placement, trunk frontal position, weight-bearing and knee moment asymmetry at seat-off during rising from a chair in healthy controls and persons with hemiparesis

OBJECTIVE: To assess the interaction of foot placement, trunk frontal position, weight-bearing and knee moment asymmetry at seat-off when rising from a chair. DESIGN: Cross-sectional study. SUBJECTS: Seventeen subjects with hemiparesis and 15 healthy controls. METHODS: Trunk position, weight-bearing and knee moment asymmetry were quantified by kinetic and kinematic analysis when the subjects rose from a chair using 3 different foot placements: spontaneous, symmetrical and asymmetrical. Asymmetry was defined by the ratio between sides. RESULTS: In the healthy controls, the spontaneous and symmetrical foot placements were associated with an almost vertical trunk position and a symmetrical weight-bearing and knee moment. The asymmetrical foot placement resulted in a trunk displacement towards the foot placed behind, with more weight-bearing and higher moment on this side. The opposite was observed in the hemiparetic participants where the spontaneous and symmetrical foot conditions determined a trunk position and an asymmetry bias towards the unaffected side. Placing the affected foot behind the other reduced the asymmetrical behaviour. CONCLUSION: Changes in weight-bearing are partly associated with the frontal trunk position, and foot placement manipulations can be used to modify weight-bearing distribution. Inference on weight-bearing is possible by observing the trunk position during the sit-to-stand task in persons with hemiparesis.
