Labiaplasty with Stable Labia Minora Retraction-Butterfly-like Approach.

Labiaplasty, referring to a surgical labia minora reduction, is the most commonly requested genital rejuvenation by women. The purpose of this article is to show an innovative maneuver in the technique for this increasingly demanded procedure. In this strategy, labia minora are attached temporarily to the internal thigh with stitches resembling an open butterfly wing. This maneuver stabilizes the redundant labia minora soft tissue, easing the evaluation of asymmetry and aiding precision in the treatment. The study investigated 12 patients, 10 presenting bilateral hypertrophic labia minora and 2 patients with only unilateral abnormal anatomy, n = 22. The mean age was 25 years. The postoperative follow-up was uneventful. All patients presented labia minora with anatomic configuration. In 1 patient, we registered immediate bleeding that needed revision. The butterfly-like maneuver with the labia minora temporarily attached to the inner thigh can ease labiaplasty with central and inferior wedge resection. It helps diagnose asymmetry and adds precision to resect the correct amount of the hypertrophic tissue.

Quality of life and clinical and demographic characteristics of patients with cutaneous squamous cell carcinoma submitted to tumor resection by double-bladed scalpel.

BACKGROUND: Non-melanoma skin cancer accounts for a third of all malignancies registered in Brazil, with squamous cell carcinoma (SCC) being one of its subtypes. It develops in photo-exposed areas, affecting social habits and causing negative influence on quality of life (QoL). OBJECTIVES: To evaluate QoL in patients with primary cutaneous SCC. METHODS: A cross-sectional study was performed in patients with clinical diagnosis of SCC, corroborated by dermoscopy and confirmed by histopathology; prior to resection of the tumor using the double-blade scalpel technique, a questionnaire on the Dermatology Life Quality Index (DLQI) was applied. RESULTS: Among the 46 evaluated patients, mean age was 67.1 ± 16.0 years, with a predominance of males, low educational level and socioeconomic status, Fitzpatrick II phototype, history of outdoor work, and tumor location in exposed photo areas. Mean DLQI was 4.02 ± 0.63, and in the categorization, 11 (23.9%) had a moderate to severe negative effect on QoL. The skin tumor had a negative impact on daily activities (33% of cases), treatment effects (30%), and symptoms and feelings (29%). Study limitations: There is no gold standard instrument for assessing QoL in dermatological patients. CONCLUSION: In the study sample, one-fourth of patients with SCC had a moderate to severe negative effect on quality of life.

Tensile strength study of the abdominal wall following laparotomy synthesis using three types of surgical wires in Wistar rats.

PURPOSE: To study the tensile strength of the abdominal wall following laparotomy synthesis utilizing three types of surgical wires. METHODS: Thirty Wistar rats were randomized into three groups of ten rats each. Each group underwent a 3cm-laparotomy which was closed with 3-0 polyglactin 910, polyglecrapone and catgut wires. After 63 days, euthanasia was performed and part of the abdominal wall was removed with which a strip was produced measuring 2.0 cm in length by 6.0 cm in width comprising the abdominal muscles with the implanted mesh. The sample was fixed in a mechanical test machine in which constant force was applied contrary to the tissue strips. Maximum force was considered, expressed in Newton, until full rupture of the tissue occurred. The non-parametrical Kruskal - Wallis test was used for the statistical analysis, admitting p

Considerations that may influence the result of trials assessing tensile strength in experimental surgery.

PURPOSE: To provide information gathered upon the execution of trials assessing tensile strength in experimental surgeries. METHODS: Descriptive study considering details on the execution of trials assessing tensile strength in experimental surgery. RESULTS: The analysis of the rupture force in a mechanical test machine is an adequate technique since it provides precise and quick results. It can, undoubtedly, be developed in this context of the eminently mechanical analysis of trials on experimental surgery. CONCLUSION: The utilization of a mechanical test machine is a useful tool in the assessment of materials' strength, providing accurate results.

[Rats resistance to fecal peritonitis when subjected to total splenectomy and auto-implant of the spleen in the retroperitoneum]. / Resistência de ratos à peritonite fecal quando submetidos a esplenectomia e auto-implante do baço no retroperitônio.

PURPOSE: This study was developed to evaluated the effects of spleen transplants in the protection against abdominal sepsis in young and old Wistar rats. METHODS: Fifty-four young and old Wistar rats were utilized (90 and 180 days respectively) being distributed in three groups as follows: Sham Group, where the animal were submitted to laparotomy with manipulation of only intestine (n=12 young and adult animals), Splenectomy Group, in which the animals were subjected to total splenectomy (n=20 young and adult animals) and an Auto-implant Group, where the animals were subjected to total splenectomy and a third of the spleen was implanted in a bag in the retroperitoneum (n=22 young and adult animals). After three months the animals were subjected to a new laparotomy with binding and caecum perforation to stimulate abdominal sepsis and were accompanied until the moment of death to establish a mortality curve. RESULTS: There was recuperation of the spleen implanted in all animals. There was no significant difference in the time of death among the groups. The young animals apparently had a better response, however it was not statistically significant. CONCLUSION: This study demonstrated that spleen implant in the retroperitoneum do not prove to be an effective protection against abdominal sepsis in comparison with the splenectomized rats.

Possible migration and histopathological analysis of injections of polymethylmethacrylate in wistar rats.

Objective. To evaluate the possible migration of polymethylmethacrylate after injections in various corporal compartments of Wistar rats. Methods. The experimental work consisted in the injection of PMMA in corporal compartments for later histopathological analysis of the locations of implants and of distant filtering organs. The dose applied in each implant was of 0.2 mL. The animals were divided into groups according to the location of the implant realized: group GB had intradermic injections in the glabella. Group SD had subdermal injections in dorsal subcutaneous tissue cells. Group IP had intraperitoneal injections in the abdomen. Group PD had intramuscular injections in the right rear leg. The rats were sacrificed 30 days after realization of the implants and tissue samples from the lung, liver, spleen, and kidney, and locations of implantation were removed for histopathological analysis. Results. Characteristic microspheres that were compatible with the presence of PMMA in any of the histological slides analyzed were not observed. One animal had an amorphous exogenous substance, with a histiocytic reaction. Twelve of the 16 lungs analyzed had locations of intraalveolar hemorrhaging. Two animals had nonspecific spleen alterations. Conclusion. The histopathological analysis of this study found no PMMA microspheres in any of the tissues analyzed.

Is animal experimentation fundamental?

The understanding about the utilization of experimental animals in scientific research and in teaching is many times a complex issue. Special attention needs to be paid to attain the understanding by the general public of the importance of animal experimentation in experimental research and in undergraduate medical teaching. Experimental teaching and research based on the availability of animals for experimentation is important and necessary for the personal and scientific development of the physician-to-be. The technological arsenal which intends to mimic experimentation animals and thus fully replace their use many times does not prove to be compatible with the reality of the living animal. The purpose of this paper is to discuss aspects concerning this topic, bringing up an issue which is complex and likely to arouse in-depth reflections.

Tensile strength study of the abdominal wall following laparotomy synthesis using three types of surgical wires in Wistar rats

PURPOSE: To study the tensile strength of the abdominal wall following laparotomy synthesis utilizing three types of surgical wires. METHODS: Thirty Wistar rats were randomized into three groups of ten rats each. Each group underwent a 3cm-laparotomy which was closed with 3-0 polyglactin 910, polyglecrapone and catgut wires. After 63 days, euthanasia was performed and part of the abdominal wall was removed with which a strip was produced measuring 2.0 cm in length by 6.0 cm in width comprising the abdominal muscles with the implanted mesh. The sample was fixed in a mechanical test machine in which constant force was applied contrary to the tissue strips. Maximum force was considered, expressed in Newton, until full rupture of the tissue occurred. The non-parametrical Kruskal - Wallis test was used for the statistical analysis, admitting p<0.05. RESULTS: The average strength of the catgut group was slightly lower (33.50 N) than that of the polyglactin group (34.23 N), the difference not being statistically significant (p=0.733). The polyglecaprone group was the one which presented the lowest strength value of all three wires analyzed (29.86 N). No statistical difference was obtained when comparing the strength values of the polyglecaprone group and the catgut group (p=0.06 ). However, when the polyglecaprone group was compared to the polyglactin 910 group no statistical difference was obtained (p=0.029). CONCLUSION: The polyglactin wire presented the highest tensile strength among the three wires analyzed, such value being statistically significant when polyglactin was compared to the polyglecaprone wire.

OBJETIVO: Estudar a resistência tênsil da parede abdominal após síntese de laparotomia utilizando três tipos de fios cirúrgicos. MÉTODOS: Trinta ratos da linhagem Wistar randomizados em três grupos de dez exemplares cada um. Em cada grupo fez-se uma laparotomia de dois centímetros que foi fechada com fios 3-0 de poliglactina 910, poliglecaprone e categute. Após 63 dias, foi feita a eutanásia e retirou-se uma área da parede abdominal com a qual fez-se uma tira medindo 2,0 cm de comprimento por 6,0 cm de largura englobando os músculos abdominais com a tela implantada. A amostra foi fixada em máquina de ensaios mecânicos na qual se aplicou força constante contrária às tiras de tecido. Foi considerada a força máxima expressa em Newton até ocorrer a ruptura total da amostra. Para a análise estatística, utilizou-se teste não paramétrico de Kruskal - Wallis admitindo-se p<0,05. RESULTADOS: A média de resistência do grupo categute foi ligeiramente menor (33.50 N) ao da poliglactina (34.23 N), sendo essa diferença não estatisticamente significativa (p=0,733). O grupo poliglecaprone foi o que apresentou menor resistência entre os três fios analisados (29.86 N). Comparando as resistências do grupo poliglecaprone ao grupo categute não se obteve significância estatística (p=0,06). Entretanto quando o grupo poliglecaprone foi comparado à poliglactina 910 houve significância estatística (p=0,029). CONCLUSÃO: O fio de poliglactina apresentou a maior resistência tênsil dentre os três fios analisados, sendo esta estatisticamente significativa quando comparado ao fio de poliglecaprone.

Resistência de ratos à peritonite fecal quando submetidos a esplenectomia e auto-implante do baço no retroperitônio / Rats resistence to fecal peritonitis when subjected to total spleenectomy and auto-implant of the spleen in the retroperitoniun

OBJETIVO: O estudo foi desenvolvido para avaliar os efeitos do autotransplante esplênico na proteção contra sepse abdominal em ratos Wistar jovens e adultos. MÉTODOS: Foram utilizados 54 ratos Wistar jovens e adultos (90 e 180 dias respectivamente) sendo distribuídos em 3 grupos: Grupo Sham, onde os animais eram submetidos a laparotomia com manipulação de alças apenas (n=6 animais jovens adultos), Grupo Esplenectomia, no qual os animais eram submetidos a esplenectomia total (n=10 animais jovens e adultos) e Grupo Auto-implante, onde os animais eram submetidos a esplenectomia total e um terço do baço era implantado em uma bolsa no retroperitônio (n=10 animais jovens e adultos). Após três meses os animais eram submetidos a nova laparotomia com ligadura e perfuração do ceco para estimular a sepse abdominal e acompanhados até o momento do óbito para estabelecimento de uma curva de mortalidade. RESULTADOS: Houve recuperação do baço implantado em todos os animais. Não houve diferença significativa entre o tempo de óbito entre os grupos. Os animais jovens aparentemente tiveram uma melhor resposta embora não estatisticamente significativa. CONCLUSÃO: Este estudo demonstrou que o auto-implante de baço no retroperitônio não provê proteção efetiva contra sepse abdominal em comparação aos ratos esplenectomizados.

Microcirurgia na regiao da face / Face microsurgery: a case report

As indicacoes de microcirurgia na regiao da face sao bastante restritas, tendo em vista tratar-se de regiao extremamente vascularizada, portanto, bastante propensa a solucoes locais ou mesmo atraves de retalhos miocutaneos regionais. A microsutura vascular (arterial e venosa) e vital para que nao ocorram tromboses posteriores. Os transplantes livres sao cirurgias chamadas "tudo ou nada", ou seja, nao ha meio termo, ou o retalho sobrevive em seu novo leito ou ele necrosa
