Electrocution method to conceal homicide A rare case report.

Killing of a human being is one of the most serious or major crimes. Assailants are very keen to conceal crime by different methods, so there may be wrong interpretation by inexperienced autopsy surgeons and hence it may lead to injustice. So it is important that our keen observation and opinion should be conclusive for the administration of justice. In this paper we are presenting a rare case which was brought by police as a case of electrocution. After meticulous autopsy and crime scene visit, the case turned to be of homicidal manner. The cause of death was manual strangulation with head injury and electrical injuries were post-mortem in nature. The deceased was under the influence of alcohol. The necessary investigations like histo-pathological examination also ruled out ante-mortem nature of electric injury. The present paper highlights the importance of meticulous autopsy and crime scene visit for determination of cause and manner of death.

Never be a roman, while you are in Rome, be a roman, while you are in Rome, (a fallacy and some times fatal also).

The unlucky deceased was a American who checked in to a star hotel in Hyderabad along with his colleagues on a company assignment. When his colleagues called him, at 11-30 am for a shopping spree, he has told them that he has back-ache and wants to take rest in his room. At about 2-30 pm again, when they contacted him on phone, no response came, at about 5-00 pm again as there was no response, with a master key the door was opened and the dead body of the deceased found on the carpet besides a long sofa with a metal beeding in a prone position with right hand under the chest and the left upper limb parallel to the body, with a disconnected cable of laptop nearer to his head which was still in switched on position. A dimmer light with a long pedestal was found beside the body with bulb towards head and base towards the feet. There was a plug point at floor level near the head of the deceased, with a insitu adapter, as the pin of the laptop cannot be inserted, directly in to it. The adaptor was loosely hanging in the socket of the plug.

Fatal gastro-duodenal perforation following electrocution: A case report.

A 45 yrs old male was accidentally electrocuted, while cooking on a locally made heater in his home. He was immediately brought to the hospital in unconscious state by the family members. After first aid he was referred to a tertiary care hospital, where he was admitted about two hrs after the incident. On admission he was unconscious, abdomen was distended, with fluid in peritoneal cavity. There was tachycardia and hypotension. Bowel sounds were absent. Electrocution burn marks were present over the right hand. Arterial blood analysis showed severe metabolic acidosis. He was immediately shifted to the ICU. His condition continued to be critical with persistent metabolic acidosis despite repeated sodium bicarbonate infusion. An exploratory laprotomy was planned to rule out abdominal visceral injuries. However the patient expired six hrs after admission to the hospital before being taken to the operation theatre. Autopsy examination showed perforated anterior wall of stomach antrum and first part of duodenum.

Laparoscopic partial nephrectomy in rats

PURPOSE: To establish an experimental model of laparoscopic partial nephrectomy (LPN) in rats and to analyze morphological alterations in the renal parenchyma utilizing an electric cautery and harmonic scalpel. METHODS: Forty Wistar rats were used, divided in 2 experiments with 20 rats each: experiment I, LPN was performed with an electric cautery and the rats were subdivided into groups A and B; experiment II, LPN was performed with a harmonic scalpel and they were subdivided into groups C and D. The animals in groups A and C were sacrificed shortly after surgery and the remnant kidney was removed to study the following variables: necroses and degeneration. In groups B and D a laparatomy was performed for retrieval of the remnant kidney on the 14th day after surgery to analyze fibrous scarring. RESULTS: For the variables necroses and fibrous scarring, the electric cautery creates, on average, greater width than that produced by the harmonic scalpel (p=0.0002 and p=0.0068 respectively). Regarding the variable of degeneration, we found no significant difference between the two types of scalpels (p=0.1267). CONCLUSIONS: LPN in rats is an adequate and feasible experimental model. The electric cautery caused greater damage to remnant renal tissue when compared to harmonic scalpel.

OBJETIVO: Estabelecer um modelo experimental de nefrectomia parcial laparoscópica (NPL) em ratos e analisar as alterações morfológicas no parênquima renal utilizando-se bisturi elétrico e harmônico. MÉTODOS: Foram utilizados 40 ratos Wistar, distribuídos em dois experimentos com 20 ratos cada: experimento I, NPL utilizando-se de bisturi elétrico e subdividindo-se os ratos em grupos A e B; experimento II, NPL realizada com bisturi harmônico e subdividindo-se os ratos em grupos C e D. Os animais dos grupos A e C foram sacrificados após a cirurgia para a remoção do rim operado e estudo das seguintes variáveis: necrose e degeneração. Nos grupos B e D a laparotomia para a retirada do rim operado foi após o décimo quarto dia de pós-operatório para a análise da cicatriz fibrosa. RESULTADOS: O bisturi elétrico provocou uma necrose e cicatriz fibrosa mais extensas em relação ao bisturi harmônico (p=0.0002 e p=0.0068 respectivamente). Em relação a variável degeneração, não houve diferença entre os tipos de bisturis (p=0.1267). CONCLUSÕES: NPL em ratos é um modelo experimental adequado e factível. O bisturi elétrico causa danos teciduais mais intensos no rim operado quando comparado com o bisturi harmônico.
