RESUMO

BACKGROUND: Capsular contracture (CC) is a common complication after breast augmentation. Autologous fat grafting may be effective for restoring tissue vascularization and function. OBJECTIVE: The authors evaluated the efficacy of autologous fat grafting in a porcine model as a treatment for CC after breast augmentation. METHODS: This prospective study was performed in 20 female 30-day-old pigs. Each animal was implanted with three 30-cc textured silicone implants (stage 1 of the experiment). Group A served as the untreated control group. To induce CC, 2 mL of autologous fibrin glue was applied to the pericapsular space in group B and C animals at implantation. Three months after implantation (stage 2), the CCs of all groups were assessed by Baker classification and applanation tonometry (AT). Liposuction was performed in group B to harvest fat for these animals. Three months after group B underwent fat grafting, all 3 groups were reevaluated. Reassessments included Baker classification, AT, histologic analysis, and tensiometry (stage 3). RESULTS: The deposition of mature and immature collagen was similar for the 3 groups. The amount of fat remaining around the implanted capsules did not differ significantly between the groups. At stage 3, group B exhibited significantly larger tonometry areas than did group C. The CCs in groups B and C were significantly thicker than those of group A, but the difference between groups B and C was not significant. Capsule rupture forces did not differ significantly between groups A and B but were significantly higher in group C compared with the other groups. CONCLUSIONS: Results in this animal model indicate that pericapsular lipoinjection may be a promising treatment for CC in humans.

RESUMO

INTRODUCTION: Scar retraction due to exposed bone in palatoplasty is the leading cause of constricted maxilla. Modern techniques have focused on minimizing the effects of scarring by reducing the exposure of the bone area. OBJECTIVE: The objective of the study was to compare the palatal mucoperiosteal detachment with minimal lateral incision, followed by their synthesis, with the maintenance of lateral areas for relaxation (similar to the von Langenbeck technique) and evaluate the transversal development of the maxilla. METHODS: A prospective, randomized study was conducted, in which the molding of the dental arch of 14 pigs in 2 stages (at 1 month and 5 months) was performed. The pigs were divided into 3 groups: group 1 underwent lateral incision of the palate for mucoperiosteal detachment and maintenance of bone exposure; group 2 underwent mucoperiosteal palatal detachment with lateral access and no bone exposure; and group 3, the control animals, did not undergo any surgical procedures. Measurements of the dental arches were compared between the groups to assess differences in the development of the maxillary transverse diameter. RESULTS: There were no animals lost during the study. Group 1 showed greater growth restriction of the transverse diameter of the maxilla (36%) when compared with groups 2 (56%) and 3 (59%). Groups 2 and 3 showed similar transverse maxillary development, with no statistical difference. CONCLUSIONS: The technique of mucoperiosteal detachment without lateral relief incision has the advantage of reducing future morbidity of a constricted maxilla. This study demonstrated that the technique described can reduce rates of maxillary underdevelopment, a significant complication inherent in the procedure for palatoplasty. The lateral incisions reduce maxillary growth by approximately 20% as compared with this technique. Level II of evidence.

RESUMO

BACKGROUND: Photography standardization is paramount for appropriate critical analysis of aesthetic surgery outcomes. Therefore, the authors designed a study to evaluate the influence of different variables in photos of patients with indications for undergoing facial rejuvenation. METHODS: This blinded prospective study was conducted by the Section of Plastic Surgery in the Hospital das Clínicas at the Federal University of Paraná. In the study, 29 patients had their photos taken in two separate settings. Photo 1, termed "preoperative" (Pre), was obtained according to the same pattern for all patients. Photo 2, termed "postoperative" (Post), was acquired on the same day using different variables to manipulate the photo outcome. No surgery was actually performed. Both photos (Pre and Post) were sent to five experienced Brazilian plastic surgeons, who provided a score for photo 2 that varied from -10 to +10 compared with photo 1. RESULTS: The photos were examined by 119 plastic surgeons. No significant improvement was observed in most of the groups, except for the group that used a flash for the Post photography (p = 0.035). Almost half of the scores (45.37 %) were above zero. The highest score was found to be ten for two photographs of the makeup group. A score of zero was assigned to 54.62 % of the photos, which means no changes occurred between the Pre and Post photos. CONCLUSION: Inadequate photographic technique can change assessments of photos in a meaningful way. All the factors evaluated had a positive impact, but the only statistically significant variable was the use of a flash in the Post group.

RESUMO

In 1955, Millard developed the concept of rotation-advancement flap to treat cleft lip. Almost 6 decades later, it remains the most popular technique worldwide. Since the technique evolved and Millard published many technical variations, we decided to ask 10 experienced cleft surgeons how they would mark Millard's 7 points in two unilateral cleft lip patient photos and compared the results. In both pictures, points 1 and 2 were marked identically among surgeons. Points 3 were located adjacent to each other, but not coincident, and the largest distances between points 3 were 4.95 mm and 4.03 mm on pictures 1 and 2, respectively. Similar patterns were obtained for points 4, eight of them were adjacent, and the greatest distance between the points was 4.39 mm. Points 5 had the most divergence between the points among evaluators, which were responsible for the different shapes of the C-flap. Points 6 also had dissimilar markings, and such difference accounts for varying resection areas among evaluators. The largest distances observed were 11.66 mm and 7 mm on pictures 1 and 2, respectively. In summary, much has changed since Millard's initial procedure, but his basic principles have survived the inexorable test of time, proving that his idea has found place among the greatest concepts of modern plastic surgery.

RESUMO

BACKGROUND: In Curitiba, systemic hypertension (SH) is the second leading cause of hospitalization and the leading cause of death from cardiovascular diseases. The protocols for the treatment of hypertension provide a systematic approach to patient management, aiming at improving the efficiency and quality of health services. OBJECTIVE: To evaluate medical professionals' compliance with the protocol of hypertension of the Municipal Health Department (MHD) of the city of Curitiba. METHODS: This was a cross-sectional observational study. The data collection for the study was conducted in four health units in Curitiba. The sample consisted of 200 hypertensive patients enrolled in the hypertension program. The collected data refers to the first two consultations. The data source was the electronic records of the health units. The protocol used for comparative analysis was the protocol of the Municipal Health Department of Curitiba. RESULTS: The non-conformity percentage between clinical practice and the protocol in the first consultation was 56.8% on hypertension grade classification, 63.8% on cardiovascular risk evaluation, and 54% on treatment. In the second consultation, the non-conformity percentage was 67% on risk evaluation, and 51.3% on treatment. CONCLUSION: The non-conformity between clinical practice and the protocol of the MHD of Curitiba was evident on hypertension grade classification, cardiovascular risk evaluation, and treatment of hypertensive patients. This non-conformity may result in low efficiency of the health service, which hinders the efforts to reduce morbidity and mortality from cardiovascular disease in the population.

RESUMO

This study evaluated the epidemiological behavior of the hepatitis A in Paraná state and compared the costs of the disease and the vaccination. This is an epidemiological descriptive study including a pharmacoeconomy analysis. We collected information in the national database reported cases (SINAN), in the mortality information system (SIM) and in the hospital information system (AIH) among 2000/2003 (Paraná State Public Health Department). We estimated the probability of one cohort of children to acquire hepatitis A during their lifetime and the costs with their treatment. We compared those costs with the cost of vaccinating the children. 14,682 hepatitis A cases were registered during the period studied, and 12,102 (82.4%) occurred in the 0-15 years-old age group. The annual incidence in the general population was 37.5/100,000. We observed 20 deaths caused by this disease; 7 of those occurred by liver failure. The estimated costs with the disease included the hospital costs, liver transplantation, liver failure treatment, and laboratory tests were high. The price of the vaccine is 10 USD/dose. Two doses are necessary to get the protection. The results showed a positive cost - benefit relation when we vaccinate children. We save 2.26 USD in treatment for each dollar invested in the vaccine. Paraná record high number of hepatitis A cases each year. We confirmed the positive cost - benefit relation when we vaccinate children against hepatitis A, reducing suffering, hospitalization, death and social costs. Vaccination against hepatitis A should be recommended in the routine of immunization program in Paraná state.
