Cytokines profile and clinical-metabolic alterations in HIV-1-infected individuals with and without lypodistrophy

Highly active antiretroviral therapy (HAART) has lead to a dramatic decrease in the morbidity of patients infected with HIV. However, metabolic side effects, including lipodystrophy and dyslipidemia, have been reported in patients treated with antiretroviral therapy (HAART). The aim of this study was to analyze the clinical and metabolic alterations and the cytokines TNF-α, IFN-γ, IL-2, IL-10 and TNF-II receptors profile in the serum of treated HIV-1-infected individuals with or without lipodystrophy. Eighty-four adult patients were analyzed, 42 females and 42 males, their mean age was 37 years old, and they received HAART for at least 15 months. These patients were ambulatory outpatients from the Infectious and Parasitary Disease Area of Botucatu School of Medicine, UNESP. Subsequently the individuals were distributed into 2 groups, G1: 42 HIV-infected individuals with lipodystrophy, and G2: 42 HIV-infected individuals without lipodystrophy. Among the antiretrovirals used, stavudine was more associated to the lipodystrophy group and zidovudine to the group without lipodystrophy. CD4, CD8, viral load, glucose, albumin, and the circulating lipid did not present any difference in the group comparison, except for triglyceride that was elevated in the lipodystrophy group and HDL which was present in low concentration in more patients of G1. The cytokines TNF-α, TNF-RII, and IL-10 profile presented high levels in the lipodystrophy group; also it was positively correlated with this group. On the other hand, IL-2 and IFN-γ presented low levels in this group. High levels of TNF-α and its receptor seem to be associated to the development of lipodystrophy in patients receiving HAART.

Medicação de alto custo para portador de sofrimento psíquico: Um estudo preliminar dos custos

The present work aims to raise the costs of high-cost drugs used to treat patients of Refractory Schizophrenia in ambulatory unit. The study was carried out in the Psychosocial Support Center, which treated 33 patients with these medications, during the period of June, 2005 to May, 2006. Data analysis disclosed that the mostly used drugs to treat the carriers of Refractory Schizophrenia were: clozapina and risperidona. It was observed that the treatment with olanzapina is more expensive than that with risperidona. The study concluded that the analysis of the consumption and costs of drugs of high cost is necessary to subside better management of the expenses and new investments in the service. Moreover, the necessity of more studies in the area was also identified to contribute with the control of costs.

Endovascular treatment of pseudoaneurysm of the thoracic aorta from a firearm injury

A 24-year-old male patient was the victim of a firearm wound that penetrated the thorax. He arrived at another hospital hemodynamically unstable and was submitted to exploratory surgery by means of bithoracotomy. A lesion of the left branch of the pulmonary artery was detected and successfully repaired. He was submitted for computer-aided tomography on the fifth postoperative day, and a lesion of the mid-thoracic aorta was detected, which formed a saccular image. Considering that the patient had already been submitted to a bithoracotomy and that a direct approach to repair would involve another thoracotomy within a short period of time, endovascular treatment was chosen in our hospital. The procedure was performed under fluoroscopy. A second computer-aided tomography indicated adequate treatment of the lesion, with no indication of an endoleak. He has undergone ambulatory follow-up for 36 months without any problem related to the procedure. While endovascular treatment of the aorta has developed enormously, multicenter studies are needed to better define the long-term results of this approach. © 2008 Published by European Association for Cardio-Thoracic Surgery.

Excision of an atypical case of palatal bone exostosis: a case report.

Bone exostosis has long been described in the literature, appearing in most cases as a torus palatinus or mandibularis. These two variations are relatively common and affect approximately 30% of the world's population. Incidence is even higher when human skulls are examined post mortem, indicating that in some cases the exostosis is small and cannot be seen under the soft tissue. Removal of an exostosis is usually associated with the construction of a prothesis, but in rare cases such as the present, the lesion enlarges enough to affect speech and feeding. Few studies have reported the removal of such a large exostosis, and all were conducted in a hospital environment. In this case, complete removal was successfully conducted in an ambulatory clinic under local anesthesia.

Clonidina como medicação pré-anestésica em facectomias: Comparação entre as doses de 100 μg e 200 μg

BACKGROUND AND OBJECTIVES: The objective of the present study was to evaluate the degree of sedation, intraocular pressure, and hemodynamic changes with premedication with low doses of oral clonidine, 100 μg and 200 μg, in outpatient cataract surgeries. METHODS: This is a randomized, double-blind, clinical study undertaken at the Universidade Federal de São Paulo with 60 patients of both genders, physical status ASA 1 and 2, ages 18 to 80 years. Patients were separated into three groups: placebo, clonidine 100 μg, and clonidine 200 μg. Intraocular pressure, heart rate, and blood pressure besides assessment of sedation were measured before and 90 minutes after the administration of clonidine. Sedation levels were classified according to the Ramsay sedation scale. RESULTS: Patients who received placebo and 100 μg of clonidine did not show reduction in heart rate, while a reduction in heart rate was observed in patients who received 200 μg of clonidine, and this difference was statistically significant. Patients who received 200 μg of clonidine also had a reduction in systolic and diastolic blood pressure (p < 0.05). One patient who received 200 μg of clonidine developed severe hypotension, with systolic pressure < 80 mmHg. Patients treated with clonidine had a reduction in intraocular pressure (p < 0.05). Ninety minutes after the oral administration of placebo and 100 μg and 200 μg of clonidine, 25%, 60%, and 80% of the patients respectively were classified as Ramsay 3 or 4. CONCLUSIONS: Clonidine 100 μg can be indicated as premedication for fasciectomies, being effective in sedation and reduction of intraocular pressure, without adverse effects on blood pressure and heart rate.

Ensaio randomizado, duplo-cego e controlado de anestesia tópica induzida por iontoforese de lidocaína

Introduction: Needle infi ltration of local anesthetic is a painful procedure, thus, a topical anesthetic is a comfortable alternative; however, it is diffi cult to deliver transcutaneous polar drugs. Iontophoresis is a noninvasive technique that uses electrical current for releasing electrically charged drugs through biological membranes. Objective: To evaluate the anesthesia induced by iontophoresis of lidocaine for a standardized painful stimulus. Material and methods: Randomized, controlled, double-blind study, involving 10 volunteers under the anesthetic effects of topical application of lidocaine gel 2% and noradrenaline 1:50,000, with or without iontophoresis of 1.85 milliamps for 13 minutes. Pain sensitivity was evaluated by the prick of a 21G needle in the arms posterior region, using a visual numerical scale. Results: Patients mean age was 50.8 ± 11.4 years. Nine of them were women. All had previously received infi ltrative anesthesia. Iontophoresis was well tolerated by volunteers. The median pain scores were 0 and 3 for the arm that received the iontophoresis and for the one that did not receive, respectively (p < 0.01). Conclusion: The anesthetic effect in the region subjected to iontophoresis suggests an effi cient and comfortable method for promoting local anesthesia in the surgical approach of pediatric, hyperalgic, or needlephobic patients.

Evolução da perda de peso entre indivíduos da fila de espera para a cirurgia bariátrica em um ambulatório multidisciplinar de atenção secundária à saúde

Objective: The objective of this study is to characterize the assistance and analyze patient's adherence to nutritional follow-up while in the waiting line for bariatric surgery in a multidisciplinary, secondary healthcare outpatient clinic. Methods: This retrospective study was based on the nutritional records of 59 patients subjected to bariatric surgery at the Hospital das Clinics de Botucatu, from 2001 to 2008. The population studied was distributed into 8 groups and analyzed according to follow-up duration. The analysis took into account the evolution of body weight and the number of follow-up visits in a given period. The Kruskal-Wallis test was used to compare data between groups while Spearman's coefficient was used to test correlations. Results: Among the 59 studied patients, 42 (71.2%) returned to the clinic at least once in six months. Of these, 67.8% lost weight while in the waiting line and 27.1% of them lost more than 10% of their body weight. The greatest weight losses in the preoperative period were found in the groups that had more than six months of nutrition follow-up. There was a mean delay of three months between return visits, which could have contributed to the low adherence to follow-up. Conclusion: The patients in the waiting line for surgery analyzed in this study presented low adherence to the long-spaced return visits. The greatest weight losses were observed in groups that had been followed for more than six months. This shows that, to achieve the desired weight loss and an adequate education process before surgery, at least six months of follow-up and regular visits are necessary.

Nurse-patient communication while performing home dialysis: The patients' perceptions

This study aimed at describing patients' perception of their communication with nurses when performing home dialysis. Data were collected from interviews guided by the question: What is communication like, between you and nurses, during home dialysis treatment? Results show participants' perception of treatment during home peritoneal dialysis [Continuous ambulatory peritoneal dialysis (CAPD)]; relationship with nurses and family and the effects of treatment on one's existence. Patients can be self-caring and they learn to value the autonomy in their own care. However, some are unable to assume the responsibility for self-care. It was discovered that the connotation of inspection that some participants attributed to the nurse's visits, led to an alienation from the education process in the CAPD education. Findings suggest that effective communication and the development of the relationship of a working partnership with patients is crucial. Improvement in the nurses' communication, aiming at adapting it to the characteristics, limitations and specific needs of each patient, is significant for achieving better outcomes. © 2010 European Dialysis and Transplant Nurses Association/European Renal Care Association.

Distribuição de fisioterapeutas entre estabelecimentos públicos e privados nos diferentes níveis de complexidade de atenção à saúde

Background: The Brazilian Health System is organized on a regional and hierarchical form with three levels of complexity of health care. The Primary Care represents the first element of a continuing health care process, complemented by specialized actions. However, the centrality of the specialized care is still a problem in Brazil, especially in the private sector. Studies on the distribution of professionals in the health system allowing the formulation of appropriate policies are needed. Objectives: To investigate the distribution of physical therapists in the levels of complexity of health care and between public and private establishments, according to data from the National Register of Health Service Providers (NRHSP). Method: A descriptive cross-sectional study was performed considering NRHSP-national bank data collected in March 2010 and demographic census 2010 data. Data were analyzed through descriptive statistics techniques. Results: We identified 53,181 registries of physical therapists, 60% linked to the private sector. Only 13% of all entries were linked to primary care. The predominance in specialized care occurred in the public sector (65%) and private sector (100%). The specialized establishments of private sector linked to the southeast region (16,043) were the main sites of physical therapists. Only the public sector in the south had a majority in the Primary Care. When considering the sizes of the cities, there is focus on specialist care in bigger cities. Conclusions: This study identified the concentration of physical therapists in the specialized care, mostly in metropolis and big cities and in the private sector, with restricted to participation in the primary care.

Occurrence of sensitivity during at-home and in-office tooth bleaching therapies with or without use of light sources

The aim of this study was to evaluate the effect of tooth bleaching with 10% carbamide peroxide (CP) or 35% hydrogen peroxide (HP), with or without quartz-tungsten-halogen light or hybrid source LED/infrared laser exposition on the occurrence duration, intensity and location of tooth sensitivity Forty patients were selected and randomly divided into four groups: GI--home bleaching with CP for 4 hours a day, over the course of 3 weeks; GII--three sessions of HP with three 10-minute applications at each session and no light source; GIII--the same procedure as GII with quartz-tungsten-halogen light irradiation; GIV--the same procedure as GII with LED/laser light irradiation. The evaluation included an appointment with each patient before and after each HP bleaching session or each weekly CP bleaching and 7, 30 and 180 days after the end of treatment. The Kruskal-Wallis test revealed that the duration and intensity of post-treatment sensitivity were significantly higher for HP than for CP (p< 0.05), and symptoms were located predominantly in anterior teeth. All bleaching methods generated sensitivity, which was more frequent in anterior teeth. However, treatment with CP generated lower sensitivity than treatment with HP independently of the light sources.

An assessment of a sequence of yoga exercises to patients with arterial hypertension

This quasi-experimental study describes the effects of a yoga sequence following hemodynamic and biochemical parameters in patients with hypertension. Thirty-three volunteers participated in the study (control = 16 and yoga = 17) for four months. Blood pressure measurements, cardiac and respiratory rate were collected monthly, while the biochemical profile was taken at the beginning and end of the program. To analyze the data, Student's t test and repeated measures analyses were performed. The yoga group showed a significant reduction of systolic blood pressure, heart and respiratory rate (p < 0.05). As for the biochemical profile, the yoga group showed correlation coefficients between initial values and final responses greater than the control of fasting glucose, total cholesterol, LDL-cholesterol and triglycerides. The elaborated sequence practice promoted significant cardiovascular and metabolic benefits. The yoga exercises performed in the proposed sequence constitute complementary non-pharmacological control of blood pressure in patients with hypertension. © 2012 Elsevier Ltd.

Lack of reliability of nanotechnology in the of free plasma DNA in samples of patients with prostate cancer

Background: Several studies seek biological markers that give diagnostic and degree of tumor development. The aim of this study was to validate the determination of plasma DNA using nanotechnology (Nanovue™-NV) in samples of 80 patients with prostate cancer. Methods. Blood samples of 80 patients of the Urology Ambulatory of Faculdade de Medicina do ABC with prostate cancer confirmed by anatomical-pathology criteria were analyzed. DNA extraction was performed using a GFX TM kit (Amersham Pharmacia Biotech, Inc, USA) following the adapted protocol. Plasma was subjected to centrifugation. Results: There was a big difference between the first and the second value obtained by NanoVue Only two samples had no differences between duplicates. Maximum difference between duplicates was 38 μg/mL. Average variation between 51 samples was 10.29 μg/mL, although 21 samples had differences above this average. No correlation was observed between pDNA obtained by traditional spectrophotometry and by nanotechnology. Conclusion: Determination of plasma DNA by nanotechnology was not reproducible. © 2013 Moreno et al; licensee BioMed Central Ltd.
