Abstract: familial hypercholesterolemia is characterized by high serum levels of total cholesterol and ldl-cholesterol. it may be homozygous or heterozygous. in homozygous patients, ldl-cholesterol levels range from 500 to 1000mg/dl and coronary artery disease is precocious, usually manifesting itself between the 2nd and 3rd decades of life. the diagnosis is often made by the presence of xanthoma tuberosum and tendinous xanthomas that appear between the 1st and 2nd decades of life. the use of high doses of statins or even unusual procedures (apheresis, partial ileal bypass surgery, liver transplantation, gene therapy), or both, is necessary for increasing survival and improving quality of life, because a reduction in cholesterol levels is essential for stabilizing the coronary artery disease and reducing xanthomas. we report our experience with 3 patients with xanthomatous familial hypercholesterolemia and coronary artery disease, who underwent partial ileal bypass surgery. their follow-up over the years (approximately 8 years) showed a mean 30% reduction in total cholesterol, with a significant reduction in the xanthomas and stabilization of the coronary artery disease.

Abstract: INTRODUCTION: Sildenafil citrate is a type 5 phosphodiesterase inhibitor, which has demonstrated excellent results in the treatment of erectile dysfunction. The effect of sildenafil citrate in the cavernous arteries of patients with erectile dysfunction has not been established yet. The objective of this study was to assess the effect of sildenafil citrate in the cavernous arteries of patients with erectile dysfunction, following an intracavernous injection of alprostadil. MATERIALS AND METHODS: 29 male patients, with mean age of 53.8 years (32 to 75 years), were prospectively evaluated. The mean time with complaint of erectile dysfunction was 50.5 months (6 to 168 months). Each patient was his own control. Patients underwent a measurement of peak systolic velocity before and after use of sildenafil citrate associated with 5 micrograms of alprostadil, through ultrasonic velocitometry Knoll/MIDUS system. In the interval between measurements, approximately 15 days, patients used 3 tablets of sildenafil at home with their partners. RESULTS: Using only 5 mcg of alprostadil, average peak systolic velocity was 23.9 cm/s, and when associated to 50 mg of sildenafil it was 24.8 cm/s. Despite the increase in the flow rate caused by sildenafil, the difference was not statistically significant, Zcalculated = - 0.695 NS (Wilcoxon test). Twenty one of the 29 patients (72.4%) showed global improvement in sexual performance with the use of sildenafil citrate at home. There was not a statistically significant correlation between the global response to sildenafil citrate and the increase in the peak systolic velocity. CONCLUSION: We concluded that, even though the use of 50 mg of sildenafil citrate associated with 5 mcg of alprostadil provides an increase in the peak systolic velocity of the cavernous arteries, there was no statistic difference in relation to alprostadil alone. There was no correlation between the global response to sildenafil and the increase in the peak systolic velocity

Abstract: the clinical and radiological pulmonary manifestations in the initial phase of schistosomiasis mansoni were studied in thirty previously healthy individuals who were simultaneously infected. the findings were compared with those concerning a control group and related to possible pathogenetic factors. the respiratory manifestations were of light or of moderate intensity, the dry cough being the most common symptom. the significant radiological alterations were: thickening of bronchial walls and beaded micronodulation, predominantly localized in the lower pulmonary fields. it was observed significant association between wheezing and ige levels, estimated by the area of immediate intradermal reaction, as well as between the number of blood eosinophils and the occurrence of radiological changes. moreover, there was correlation between the worm burden and the presence of wheezing, thoracic pain and beaded micronodulation. thus, the clinical and radiological pulmonary manifestations described are significant part of the initial phase of schistosomiasis mansoni and present the worm burden, eosinophilia and levels of ige as probable pathogenetic factors.

Abstract: objective: to evaluate the initial clinical experience with the helex septal occluder for percutaneous closure of atrial septal defects. methods: ten patients underwent the procedure, 7 patients with ostium secundum atrial septal defects (asd) with hemodynamic repercussions and 3 patients with pervious foramen ovale (pfo) and a history of stroke. mean age was 33.8 years and mean weight was 55.4 kg. mean diameter by transesophageal echocardiography and mean stretched asd diameter were 11.33 ± 3.3mm, and 15.2 ± 3.8mm, respectively. the qp/qs ratio was 1.9 ± 0.3 in patients with asd. results: eleven occluders were placed because a patient with 2 holes needed 2 devices. it was necessary to retrieve and replace 4 devices in 3 patients. we observed immediate residual shunt (< 2mm) in 4 patients with asd, and in those with patent foramen ovale total occlusion of the defect occurred. no complications were noted, and all patients were discharged on the following day. after 1 month, 2 patients with asd experienced trivial residual shunts (1mm). in 1 patient, we observed mild prolapse in the proximal disk in the right atrium, without consequences. conclusion: the helex septal occluder was safe and effective for occluding small to moderate atrial septal defects. because the implantation technique is demanding, it requires specific training of the operator. even so, small technical failures may occur in the beginning of the learning curve, but they do not involve patient safety.

Abstract: among the different properties that influence bone apposition around implants, the chemical or biochemical composition of implant surface may interfere on its acceptance by the surrounding bone. the aim of this study was to investigate if a biofunctionalization of implant surface influences the bone apposition in a dog model and to compare it with other surfaces, such as a microstructured created by the grit-blasting/acid-etching process. eight young adult male mongrel dogs had the bilateral mandibular premolars extracted and each one received 6 implants after 12 weeks, totaling 48 implants in the experiment. four groups of implants were formed with the same microrough topography with or without some kind of biofunctionalization treatment. after histomorphometric analysis, it was observed that the modified microstructured surface with a "low concentration of the bioactive peptide" provided a higher adjacent bone density (54.6%) when compared to the other groups (microstructured + ha coating = 46.0%, microstructured only = 45.3% and microstructured + "high concentration of the bioactive peptide" = 40.7%), but this difference was not statistically significant. in conclusion, biofunctionalization of the implant surface might interfere in the bone apposition around implants, especially in terms of bone density. different concentrations of bioactive peptide lead to different results.

Abstract: smokers have small root coverage which is associated with bad vascularity of periodontal tissues. this study evaluated a technique that can increase the blood supply to the periodontal tissues compared with a traditional technique. twenty heavy smokers (10 males and 10 females) with two bilateral miller class i gingival recessions received coronally positioned flaps in one side (control group)and extended flap technique in the other side (test group). clinical measurements (probing pocket depth, clinical attachment level, bleeding on probing, gingival recession height, gingival recession width, amount of keratinized tissue, and width and height of the papillae adjacent to the recession) were determined at baseline, 3 and 6 months postoperatively. salivary cotinina samples were taken as an indicator of the nicotine exposure level. no statistically significant differences (p>0.05) were detected for the clinical measurements or smoke exposure. both techniques promoted low root coverage (control group: 43.18% and test group: 44.52%). in conclusion, no difference was found in root coverage between the techniques. root coverage is possible and uneventful even, if rather low, in heavy smoker patients with low plaque and bleeding indices.
