Fasciotomia em membro superior após síndrome compartimental por acidente ofídico com posterior enxertia e plástica em Z: relato de caso / Fasciotomy in the upper limb after compartment syndrome due to snakebite with subsequent grafting and z-plasty: case report

Este relato de caso aborda o curso clínico de um envenenamento botrópico ocorrido no município de Jarinu, SP, no ano de 2021. O paciente necessitou de fasciotomia em membro superior após síndrome compartimental aguda com enxertia dermoepidérmica em um segundo momento cirúrgico. No pós-operatório tardio, o paciente evoluiu com retração, necessitando de reabordagem cirúrgica com correção de retração de membro superior esquerdo. Discute-se a gravidade do acidente ofídico, efeitos do veneno nos tecidos, complicações, síndrome compartimental aguda, indicação e técnica da fasciotomia descompressiva com base na literatura.

This case study examines the clinical course of a Bothrops snakebite poisoning that occurred in Jarinu, São Paulo, Brazil, in 2021. The patient required a fasciotomy in the upper limb due to acute compartment syndrome, followed by a second surgical procedure involving dermo-epidermal grafting. In the late postoperative period, the patient experienced retraction, leading to a subsequent surgical intervention to correct the retraction in the left upper limb. The severity of the snakebite accident, the effects of venom on tissues, complications, acute compartment syndrome, as well as the indications and techniques for decompressive fasciotomy, are discussed based on the available literature.

Post-bariatric abdominoplasty: skin sensation evaluation.

BACKGROUND: The number of bariatric surgeries is progressively increasing in the USA and in Brazil. The number of post-bariatric plastic surgeries also increases as a response to this phenomenon. Abdominoplasties performed in former morbidly obese patients present a larger number of postoperative complications. Studies show that abdominoplasty caused postoperative skin hypesthesia. This study aims at evaluating skin sensibility/sensation in post-bariatric patients submitted to anchor-line abdominoplasty with clinical, qualitative, reliable and reproductive methods. METHODS: Thirty-nine former morbidly obese women after open Roux-en-Y Gastric Bypass were evaluated for skin tactile pain, touch in movement, noxious and innocuous thermal sensibility and vibration. Fifteen patients composed the Control group (which did not undergo abdominoplasty) and 24 patients composed the Study group (which was submitted to anchor-line abdominoplasty without flap undermining). The sensations were evaluated before and after the abdominoplasty. RESULTS: The Control group which did not undergo abdominoplasty showed nearly 100% of positivity to all sensory modalities exception made to vibration which was 56.4-62.2-64.9%. Surprisingly, the Study group showed the same sensation maintenance after the abdominoplasty for nearly all modalities, vibration showed improvement (56.7-71.1-78.3%) without statistical value (p = 0.67). CONCLUSION: There was skin sensation maintenance after anchor-line post-bariatric abdominoplasty. Non-undermining of xipho-pubic flap is a possible reason for this discovery.

Basal cell carcinoma: an updated epidemiological and therapeutically profile of an urban population.

PURPOSE: To describe the epidemiological profile of basal cell carcinoma patients at a private hospital in São Paulo and to evaluate the treatment adopted. METHODS: A prospective study of 202 patients, on which 253 lesions were diagnosed for histopathological exam as basal cell carcinoma within the period of January 2001 to September 2003, in the Plastic Surgery Residency Program at the Hospital Jaraguá. The susceptibility factor of the host, the environment variables, the characteristics of the lesions and the efficacy of the treatment were examined. The data were statistically evaluated. RESULTS: The incidence of basal cell carcinoma was 126 cases per 100,000 patients in a period of 32 months (36 cases per 100,000 patients/year). The patients were evenly distributed in terms of sex: 48% male and 52% female. The greater incidence was in patients between the ages of 60 and 80 years and the average was 64 years. The survey revealed susceptibility factors such as white race and phototypes I and II in 95.5% of the patients. Exposition to ultraviolet radiation was reported by 77% of the patients and the most frequent location of tumors was on the face (71.2% of the cases). Actinic keratosis and a history of skin cancer were reported in 43.6% and in 25% of the cases, respectively. The adopted treatment was surgery in 99.4% of the cases and only one patient was treated with radiotherapy. Twenty lesions (8%) had incomplete excision. The recurrence rate was 2% (5 cases). There were no cases with metastasis or fatal outcome. CONCLUSIONS: The factors related to the development of basal cell cancer which were significantly present in the population surveyed were: older age, white individuals, phototypes I and II, presence of actinic keratosis, previous history of non-melanoma skin cancer and exposure to ultra-violet rays both in recreational and in occupational form. The surgical treatment employed was effective with a rate of incomplete excision and recurrence similar to those found in the literature.

Basal cell carcinoma: an updated epidemiological and therapeutically profile of an urban population

OBJETIVO: Traçar o perfil epidemiológico dos portadores de carcinoma basocelular e , avaliar o tratamento instituído no Serviço de Residência de Cirurgia Plástica do Hospital Jaraguá. MÉTODOS: Foi realizado um estudo prospectivo de 202 pacientes, nos quais foram diagnosticados 253 lesões por exame anátomo-patológico como carcinoma basocelular no período de janeiro de 2001 a setembro de 2003, no Serviço de Residência de Cirurgia Plástica do Hospital Jaraguá. Foram abordados fatores de susceptibilidade do hospedeiro, fatores ambientais, características das lesões, o tratamento instituído e sua eficácia. Os dados encontrados foram submetidos à análise estatística. RESULTADOS: A incidência de carcinoma basocelular encontrada foi de 126 casos/ 100.000 pacientes em 32 meses (36casos/100.000 pacientes/ano). Os pacientes se distribuíram de forma semelhante entre os sexos masculino (48%), e feminino (52%), com uma incidência maior na faixa etária entre 60 e 80 anos (69%), com média de 64,0 anos. A amostra apresentou fatores de susceptibilidade como a raça branca e fototipos I e II em 95,5% dos pacientes. A exposição à radiação ultravioleta foi informada por 77% dos pacientes, e a localização mais freqüente dos tumores foi a face, em 71,2% dos casos. A ceratose actínica e a história de câncer de pele anterior estavam presentes em 43,6% e 25,8%, respectivamente. O tratamento instituído foi o cirúrgico em 99,4% dos casos, sendo que um caso foi tratado com radioterapia por falta de condições clínicas. No anátomo-patológico foram encontradas 20 lesões (8%) com margens comprometidas pelo tumor. A taxa de recidiva no acompanhamento pós-operatório foi de 2% (5 casos). Não houve casos de metástase ou óbito. CONCLUSÕES: Os fatores relacionados ao desenvolvimento do carcinoma basocelular que estão presentes de forma significante na população estudada são: idade avançada,raça branca, fototipos I e II, presença de ceratose actínica, história anterior de câncer de pele não-melanoma e exposição aos raios ultra-violetas tanto de forma recreacional quanto ocupacional.O tratamento instituído foi efetivo com taxas de margens comprometidas e recidivas comparáveis com as da literatura.

Ondansetron for the prevention of postoperative nausea and vomiting: which is the best dosage for aesthetic plastic surgery?

BACKGROUND: Ondansetron has been used widely in plastic surgery to prevent postoperative nausea and vomiting. A literature search showed controversial dosages of this drug, and because of its short half-life, its use only before anesthetic induction could have a limited effect. The purpose of this study was to assess the efficacy of intravenous (IV) ondansetron (4 mg) for aesthetic plastic surgery performed with the patient under general anesthesia and the prophylaxis of postoperative nausea and vomiting (PONV) in two situations: (a) only before anesthetic induction and (b) before anesthetic induction and immediately before extubation. METHODS: Of the 60 patients who had general anesthesia for aesthetic plastic surgery, 30 received 4 mg of IV ondansetron before anesthetic induction (control group) and 30 received 4 mg of IV ondansetron before anesthetic induction plus 4 mg IV immediately before extubation (experimental group). The PONV was recorded in the postanesthetic care unit and in the hospital room. RESULTS: The total occurrence of PONV (n = 60) was 6.7%. In the postanesthetic care unit, one patient in the experimental group (3.3%) manifested this symptom. In the hospital room, two patients in the control group (6.7%) and one patient in the experimental group (3.3%) manifested PONV. CONCLUSION: According to the findings, there was no statistical difference between the groups. However, the dosage used in the control group was effective and less expensive.

Risk of glove perforation in minor and major plastic surgery procedures.

BACKGROUND: Incidental needlestick injury with exposure of blood pathogens has a high incidence among health care workers. Because plastic surgeons make up an important risk group for this type of accident, this study sought to evaluate the incidence of glove perforation during minor and major plastic surgery procedures. METHODS: Evidence of glove perforation was evaluated for 390 gloves after 100 consecutive minor surgical procedures and for 710 gloves after 100 consecutive major surgeries using Maffuli's test. An index based on the number of first assistant's glove perforation and the surgical time was created to compare these accidents associated with both types of procedures. RESULTS: Glove perforations were found in four gloves (1.02%) after minor surgery and 76 gloves (21.40%) after major surgery. During minor surgeries, the assistant was more likely to have exposure than the surgeon. During major surgery, the surgeon experienced more glove perforations (59.21%) than the assistant (40.79%). The most common location of perforations was the palmar face of the left hand in both groups. The surgeons did not notice these perforations at any time. The duration of the minor procedures varied from 10 to 30 min (average, 17.55 min), whereas the time of major procedures ranged from 1 to 6 h (average, 186 min). There was no statistical significant difference in the perforation's index between minor and major procedures. CONCLUSIONS: The risk of perforation to the surgeon's glove during minor surgery is minimal. The frequency of perforation to the first assistant's glove is similar between minor and major plastic surgery procedures.
