Disintegration of magnetic tablets in human stomach evaluated by alternate current biosusceptometry

Oral administration is the most convenient route for drug therapy. The knowledge of the gastrointestinal transit and specific site for drug delivery is a prerequisite for development of dosage forms. The aim of this work was to demonstrate that is possible to monitor the disintegration process of film-coated magnetic tablets by multi-sensor alternate current Biosusceptometry (ACB) in vivo and in vitro. This method is based on the recording of signals produced by the magnetic tablet using a seven sensors array and signal-processing techniques. The disintegration was confirmed by signals analysis in healthy human volunteers' measurements and in vitro experiments. Results showed that ACB is efficient to characterize the disintegration of dosage forms in the stomach, being a research tool for the development of new pharmaceutical dosage forms.

Phantom eye syndrome: a review of the literature

The purpose of this literature review was to describe the main features of phantom eye syndrome in relation to their possible causes, symptoms, treatments, and influence of eye amputation on quality of life of anophthalmic patients. For this, a bibliographical research was performed in Pubmed database using the following terms: eye amputation, eye trauma, phantom eye syndrome, phantom pain, and quality of life, associated or not. Thirteen studies were selected, besides some relevant references contained in the selected manuscripts and other studies hallowed in the literature. Thus, 56 articles were included in this review. The phantom eye syndrome is defined as any sensation reported by the patient with anophthalmia, originated anophthalmic cavity. In phantom eye syndrome, at least one of these three symptoms has to be present: phantom vision, phantom pain, and phantom sensations. This syndrome has a direct influence on the quality of life of the patients, and psychological support is recommended before and after the amputation of the eyeball as well as aid in the treatment of the syndrome. Therefore, it is suggested that, for more effective treatment of phantom eye syndrome, drug therapy should be associated with psychological approach.

Hypothalamic energy metabolism is impaired by doxorubicin independently of inflammation in non-tumour-bearing rats

We sought to explore the effects of doxorubicin on inflammatory profiles and energy metabolism in the hypothalamus of rats. To investigate these effects, we formed two groups: a control (C) group and a Doxorubicin (DOXO) group. Sixteen rats were randomly assigned to either the control (C) or DOXO groups. The hypothalamus was collected. The levels of interleukin (IL)-1β, IL-6, IL-10, TNF-α and energy metabolism (malate dehydrogenase, complex I and III activities) were analysed in the hypothalamus. The DOXO group exhibited a decreased body weight (p < 0.01). Hypothalamic malate dehydrogenase activity was reduced when compared with control (p < 0.05). In addition, pro-inflammatory cytokine levels were unchanged. Therefore, our results demonstrate that doxorubicin leads to an impairment of \hypothalamic energy metabolism, but do not affect the inflammatory pathway. Copyright © 2015 John Wiley & Sons, Ltd. Conflict of Interest Significance paragraph The hypothalamus is a central organ that regulates a great number of functions, such as food intake, temperature and energy expenditure, among others. Doxorubicin can lead to deep anorexia and metabolic chaos; thus, we observed the effect of this chemotherapeutic drug on the inflammation and metabolism in rats after the administration of doxorubicin in order to understand the central effect in the hypothalamus. Drug treatment by doxorubicin is used as a cancer therapy; however the use of this drug may cause harmful alterations to the metabolism. Thus, further investigations are needed on the impact of drug therapy over the long term.

Assistência cirúrgico-odontológica a pacientes com história de infarto do miocárdio

The execution of a appropriate odontological surgical treatment for patients with Myocardial Infarction has been based in established protocols for important works in world wide literature during the sixty’s and seventy’s decade, established with a minimum of six months before the noncardiac surgery. The recent advancements in the medical assessment of surgical risk based on the individual analysis of each case with availability of new therapeutic tools in reference to medical or dental treatment, allowing for new procedures that can be used in the execution of safer odontological surgery for each patients. This review of the literature shows the actual tendencies of the treatment of patients with Myocardial Infarction concerning specific care before, during and after surgery based on laboratory evaluation and drug therapy as well as the possibility of surgical treatment before six months post-infarction.

Terapéutica alternativa asociada al bruxismo: revisión de literatura

The aim of this study was to review the literature in order to discuss the main and the most effective therapeutic activities to control the nocturnal bruxism. To identify the studies included in this review, it was conducted a detailed and advanced search strategy in the PubMed and Medline databases. It was used as KEY WORDS: bruxism, therapeutics and drug therapy. Inclusion criteria were: case reports, randomized controlled trials, in vitro studies, literature reviews and systematic reviews with or without meta-analysis of the past 10 years that addressed the theme. Exclusion criteria were: articles without abstract, animal studies, articles whose first language was not English and articles from journals that do not belong to the dentario field. From a total of 83 articles, after an analysis according to the inclusion and exclusion criteria, 33 articles were selected. Despite the fact that there is a small number of prospective clinical studies with high degree of reliability and most studies that evaluated the alternative treatments effectiveness are isolated case reports, the current literature shows that the use of botulinum toxin has been shown to be effective in the control of nocturnal bruxism. On the other hand, important aspects such as transitory effect, safe dosage and application technique are still little discussed, then, further studies are needed to have these doubts clarified.

Autocuidado na percepção de pessoas com hanseníase sob a ótica da complexidade

Objective: This study aimed to understand how patients with Hansen's Disease perceive self-care from the complexity perspective. Methods: Qualitative, descriptive and exploratory study based on the Collective Subject Discourse. Results: Sample composed of 15 subjects, most of whom were married males (66.6%) with a mean age of 52.3 years and were classified in the polarized forms of the disease. The following themes emerged from the DCS synthesis: having Hansen's Disease, drug therapy, self-care and lifestyle. The study provided visibility to the vertical model, which is largely hegemonic in the tradition of public health care policies, showing concern about only treating the disease, disregarding the complex relationships involved. Conclusion: Acknowledging these limitations and setting strategies to change them in favor of the dialogue among interprofessional team members are challenges to further develop self-care practices and to empower patients in relation to treatment and disease.

Periocular basal cell carcinoma: cost of topical immunotherapy versus estimated cost of surgical treatment

Purpose: The objective of this study was to compare the estimated cost of clinical and surgical treatment for basl cell carcinoma of the eyelid. Methods: This was a pilot study of 12 patients with basal cell carcinoma receiving treatment with 5% imiquimod cream at the ocular plastic surgery center, medical school University of Sao Paulo (HC-FMUSP, Brazil). The cost of clinical treatment was estimated based on the time of treatment and amount of medication consumed by patients in the home setting. The cost of surgical treatment was estimated by ophthalmologists with experience in reconstructive plastic surgery based on analysis of images of the same patients. Surgeons responded to a questionnaire with four questions about surgical technique, surgical materials required, estimated duration of surgery and type of anesthesia. Results: Immunotherapy lasted from 8 to 12 weeks. All patients reported each cold-stored sachet with 5% imiquimod cream lasted 3 days. According to the institution, a box with 12 sachets costs BRL 480.00. Patients required 1.58-3.11 boxes for complete treatment, corresponding to a total cost of BRL 758.40-1,492.80. Based on image analysis, surgeons evaluated surgery would require 1-3 hours. The estimated cost of surgery room and staff was BRL 263.00, to which the cost of supplies was added. Thus, the total cost of surgical treatment was BRL 272.61-864.82. On the average, immunotherapy was 57,64% more costly than surgical treatment. Conclusions: Malignant eyelid tumors are a common finding in clinical ophthalmology. Surgery is still the treatment of choice at our institution, but immunotherapy with 5% imiquimod cream may be indicated for patients with multiple lesions or high surgical risk and for patients declining surgery for reasons of fear or esthetic concerns. The ability to estimate costs related to the treatment of malignant eyelid tumors is an important aid in the financial planning of health care institutions. Further studies should evaluate the possibility of institutions equating the cost of immunotherapy and surgical treatment by acquiring similar but less expensive medications.

The effects on mucociliary clearance of prednisone associated with bronchial section

OBJECTIVE: Infections have been and remain the major cause of morbidity and mortality after lung transplantation. Because mucociliary clearance plays an important role in human defense mechanisms, the influence of drugs on the mucociliary epithelium of patients undergoing lung transplantation must be examined. Prednisone is the most important corticosteroid used after lung transplantation. The aim of this study was to evaluate the effects of bronchial transection and prednisone therapy on mucociliary clearance. METHODS: A total of 120 rats were assigned to 4 groups according to surgical procedure or drug therapy: prednisone therapy (1.25 mg/kg/day); bronchial section and anastomosis + prednisone therapy (1.25 mg/kg/day); bronchial section + saline solution (2 ml/day); and saline solution (2 ml/day). After 7, 15, or 30 days, the animals were sacrificed, and the lungs were removed from the thoracic cavity. The in situ mucociliary transport velocity, ciliary beat frequency and in vitro mucus transportability were evaluated. RESULTS: Animals undergoing bronchial section surgery and anastomosis had a significant decrease in the ciliary beat frequency and mucociliary transport velocity 7 and 15 days after surgery (p<0.001). These parameters were normalized 30 days after the surgical procedure. Prednisone improved mucous transportability in the animals undergoing bronchial section and anastomosis at 15 and 30 days (p<0.05). CONCLUSION: Bronchial section and anastomosis decrease mucociliary clearance in the early postoperative period. Prednisone therapy improves mucus transportability in animals undergoing bronchial section and anastomosis.
