Coma irreversível em paciente portadora de esquizofrenia paranóide: encefalopatia de Wernicke após síndrome de realimentação: um relato de caso / Irreversible coma in a patient with paranoid schizophrenia: Wernicke encephalopathy after refeeding syndrome: a case report

Encefalopatia de Wernicke (EW) e síndrome de realimentação (SR) são duas condições frequentemente coexistentes, subdiagnosticadas e que podem implicar prognóstico reservado após sua instalação. Sua identificação precoce representa um desafio para os intensivistas, haja vista a falta de sensibilidade e especificidade das manifestações clínicas. Apresenta-se um relato de caso de uma paciente portadora de esquizofrenia paranoide, sem histórico de abuso de álcool, que desenvolveu quadro de coma irreversível após greve de fome, sendo feito diagnóstico tardio de EW associada a SR. Descreve-se a evolução clínica e neuropsiquiátrica com o intuito de enfatizar a necessidade crucial de alta suspeição diagnóstica, com reposição vitamínica imediata, vigilância de distúrbios eletrolíticos e progressão parcimoniosa do aporte nutricional.

Wernicke encephalopathy (WE) and refeeding syndrome (RFS) are two often coexisting, underdiagnosed conditions that may involve a poor prognosis after their onset. Early identification represents a challenge for intensivists, given the lack of sensitivity and specificity of clinical manifestations. We report a case of a patient with paranoid schizophrenia, without a history of alcohol abuse, who developed irreversible coma after a hunger strike, with a late diagnosis of WE associated with RFS. The clinical and neuropsychiatric outcomes are described herein in order to emphasize the crucial need for a high diagnostic suspicion, with immediate vitamin replacement, monitoring of electrolyte disorders, and gradual progression of nutritional support.

Trastornos prolongados de conciencia postinjuria cerebral aguda / Prolonged disorders of consciousness after an acute brain injury

Only a fraction of patients in coma secondary to a primary acute brain injury develop a vegetative state (VS). At least 20% of patients show late transitions to a minimally conscious states (MCS). They are particularly common in young adults with traumatic brain injury. The main problems faced by clinicians are the diagnostic accuracy of VS and MCS as well as the usefulness of sophisticated paraclinical investigations. Specific therapies are of limited effectiveness. This population is vulnerable to misdiagnosis and limited access to medical care and rehabilitation, thus generating ethical problems.

Coma secundario a síndrome del trefinado / Coma due to syndrome of the trephined

El síndrome del trefinado o craniectomizado abarca manifestaciones neurológicas asociadas a la depresión del flap cutáneo y se distingue del síndrome postraumático por su reversibilidad con el tratamiento reparador del defecto craneano. El coma no es una forma habitual de presentación. Comunicamos un caso de presentación atípica en un hombre de 36 años de edad con antecedente de craniectomía descompresiva, que presentó un cuadro de deterioro neurológico profundo atribuible al síndrome del trefinado, el cual revirtió tras la craneoplastía. En la fisiopatología del síndrome intervienen trastornos cerebrovasculares, metabólicos, hidrodinámicos del líquido cefalorraquídeo e hiperdinamismo de las estructuras encefálicas. El gold standard terapéutico es la craneoplastía. Se requieren estudios de mayor peso estadístico para determinar el tiempo quirúrgico apropiado.

The syndrome of the trephined or craniectomized is commonly referred as neurological manifestations associated to skin flap depression and reversible after craneoplasty, which allows its differentiation from post-traumatic syndrome. We present the case of a male patient, 36 years old, with history of decompressive craniectomy. He evolved with sudden neurological worsening associated to syndrome of the trephined and recovery after craneoplasty. Physiopathology of the syndrome involves cerebrovascular, metabolic and cerebrospinal fluid hydrodynamic disturbances as well as parenchymal hyperdynamic mechanisms. Cranioplasty is the gold standard treatment. Still, studies with statistical power are needed to assess correct surgical timing.

Coma mixedematoso / Myxedema coma

El hipotiroidismo es una enfermedad frecuente, de diagnóstico y tratamiento simples. Si no es detectada a tiempo puede progresar a la forma más grave conocida como coma mixedematoso. El término "coma mixedematoso" es considerado generalmente engañoso, ya que la mayoría de los pacientes no se presenta inicialmente en estado de coma. La progresión típica es la letargia, evolucionando al estupor y eventualmente al coma, con insuficiencia respiratoria e hipotermia. Es relativamente infrecuente, afecta fundamentalmente a mujeres ancianas, y a menudo ocurre en invierno. Esta entidad debe ser considerada una forma de hipotiroidismo descompensado, desencadenada a partir de una variedad de enfermedades o condiciones no tiroideas que provocan un compromiso sistémico generalizado de extrema gravedad, con desenlace fatal de no mediar un diagnóstico precoz y un tratamiento intensivo.

Hypothyroidism is a frequently diagnosed and simply treated disease. If not recognised, however, in time it may develop into the most severe manifestation of hypothyroidism known as myxedema coma. The term "myxedema coma" is generally seen as misleading since most patients do not initially present in a coma. The typical progression is lethargy evolving into stupor and, eventually, into coma with respiratory failure and hypothermia. It mainly affects elderly women, often occurring in winter and is relatively rare. It can be considered a form of decompensated hypothyroidism often triggered by a variety of non-thyroid conditions or diseases provoking an extremely severe condition of multiple system failure with lethal consequences unless an early diagnosis is made and an aggressive treatment is administered.

Multiple causes of hyponatremia: a case report

Objective:To present a case with 4 different potential causes of hyponatremia

Clinical Presentation and Intervention: The patient presented with the following symptoms: nausea, vomiting, diarrhea, and dark urine after drinking large amounts of fluids that included alcohol and caffeine. Laboratory, microbiological, and morphological examinations revealed the existence of severe hyponatremia and acute poststreptococcal glomerulonephritis. The patient developed acute symptomatic seizures and coma. Gradual normalization of the sodium level led to a recovery of consciousness

Conclusion:Treatment with hypertonic sodium, fluid restriction, and antibiotics led to a complete recovery. In the case of multiple causes of hyponatremia, it is necessary to treat all causes

Hipotermia terapêutica após parada cardíaca: preditores de prognóstico / Therapeutic hypothermia after cardiac arrest: outcome predictors

Resumo Objetivo: A determinação do prognóstico de pacientes em coma após parada cardíaca tem implicações clínicas, éticas e sociais. Exame neurológico, marcadores de imagem e bioquímicos são ferramentas úteis e bem aceitas na previsão da recuperação. Com o advento da hipotermia terapêutica, tais informações devem de ser confirmadas. Neste estudo procurou-se determinar a validade de diferentes marcadores que podem ser utilizados na detecção de pacientes com mau prognóstico durante um protocolo de hipotermia. Métodos: Foram coletados prospectivamente os dados de pacientes adultos, internados após parada cardíaca em nossa unidade de terapia intensiva para realização de protocolo de hipotermia. Nosso intuito foi realizar um estudo descritivo e analítico para analisar a relação entre os dados clínicos, parâmetros neurofisiológicos, de imagem e bioquímicos, e o desfecho após 6 meses, conforme definido pela escala Cerebral Performance Categories (bom, se 1-2, e mau, se 3-5). Foi coletada uma amostra para determinação de neuroenolase após 72 horas. Os exames de imagem e neurofisiológicos foram realizados 24 horas após o período de reaquecimento. Resultados: Foram incluídos 67 pacientes, dos quais 12 tiveram evolução neurológica favorável. Fibrilação ventricular e atividade teta no eletroencefalograma se associaram a bom prognóstico. Pacientes submetidos a resfriamento mais rápido (tempo médio de 163 versus 312 minutos), com lesão cerebral causada por hipóxia/isquemia detectada na ressonância nuclear magnética ou níveis de neuroenolase superiores a 58ng/mL se associaram a desfecho neurológico desfavorável (p < 0,05). Conclusão: A presença de lesão cerebral causada por hipóxia/isquemia e de neuroenolase foram fortes preditores de má evolução neurológica. Apesar da crença de que atingir rapidamente a temperatura alvo da hipotermia melhora o prognóstico neurológico, nosso estudo demonstrou que este fator se associou a um aumento da mortalidade e a uma pior evolução neurológica.

ABSTRACT Objective: The determination of coma patient prognosis after cardiac arrest has clinical, ethical and social implications. Neurological examination, imaging and biochemical markers are helpful tools accepted as reliable in predicting recovery. With the advent of therapeutic hypothermia, these data need to be reconfirmed. In this study, we attempted to determine the validity of different markers, which can be used in the detection of patients with poor prognosis under hypothermia. Methods: Data from adult patients admitted to our intensive care unit for a hypothermia protocol after cardiac arrest were recorded prospectively to generate a descriptive and analytical study analyzing the relationship between clinical, neurophysiological, imaging and biochemical parameters with 6-month outcomes defined according to the Cerebral Performance Categories scale (good 1-2, poor 3-5). Neuron-specific enolase was collected at 72 hours. Imaging and neurophysiologic exams were carried out in the 24 hours after the rewarming period. Results: Sixty-seven patients were included in the study, of which 12 had good neurological outcomes. Ventricular fibrillation and electroencephalographic theta activity were associated with increased likelihood of survival and improved neurological outcomes. Patients who had more rapid cooling (mean time of 163 versus 312 minutes), hypoxic-ischemic brain injury on magnetic resonance imaging or neuron-specific enolase > 58ng/mL had poor neurological outcomes (p < 0.05). Conclusion: Hypoxic-ischemic brain injury on magnetic resonance imaging and neuron-specific enolase were strong predictors of poor neurological outcomes. Although there is the belief that early achievement of target temperature improves neurological prognoses, in our study, there were increased mortality and worse neurological outcomes with earlier target-temperature achievement.

Coma mixedematoso em paciente com neurofibromatose tipo 1: associação rara / Myxedema coma in a patient with type 1 neurofibromatosis: rare association

O coma mixedematoso (CM) é uma emergência endocrinológica rara, porém letal e consiste na expressão extrema do hipotireoidismo. Relatamos o caso de um paciente do sexo masculino, 51 anos, que abandonou tratamento do hipotireoidismo por 10 meses e evoluiu com sintomas de letargia, edema e intolerância ao frio que culminaram em insuficiência respiratória e coma. Apresentava também diagnóstico prévio de neurofibromatose. O diagnóstico precoce do coma mixedematoso aliado à instituição imediata do tratamento com levotiroxina e ao manejo adequado de complicações, como insuficiência respiratória, choque cardiogênico associado a swinging heart, insuficiências adrenal e renal agudas e sepse, permitiu a evolução favorável do quadro.

Myxedema coma, a rare but fatal emergency, is an extreme expression of hypothyroidism. We describe a 51-year-old male patient who has discontinued hypothyroidism treatment 10 months earlier and developed lethargy, edema, and cold intolerance symptoms. He also had a previous diagnosis of neurofibromatosis. After admission, he progressed to respiratory insufficiency and coma. The prompt recognition of the condition, thyroid hormone replacement, and management of the complications (hypoventilation, cardiogenic shock associated with swinging heart, adrenal and renal insufficiency and sepsis), resulted in a favorable evolution.

Coma mixedematoso en hombre de 74 años: reporte de caso con revisión narrativa / Myxedema coma in a 74 year old man: case report and narrative review

Las células foliculares de la glándula tiroides producen las hormonas tiroxina y triyodotironina, reguladas por la hormona tirotrópica de la hipófisis anterior o tiroestimulante. El coma mixedematoso es definido como un hipotiroidismo profundo que se caracteriza por alteraciones de la conciencia que van desde letargia, estupor y coma al cual se asocia hipotermia, hipoglucemia, convulsiones, hipotensión arterial y manifestaciones de un hipotiroidismo descompensado. La causa o factor desencadenante puede prevenirse si existe diagnóstico previo de hipotiroidismo primario con tratamiento sustitutivo de hormonas tiroideas bien establecido o bien, si en ausencia de diagnóstico éste se sospecha y se trata adecuadamente. Constituye una urgencia médica de mortalidad elevada, donde los factores medioambientales como el frío, infecciones severas e intoxicaciones medicamentosas son importantes factores desencadenantes. Se presenta el caso de un adulto mayor de 74 años, de sexo masculino, sin antecedentes de enfermedad tiroidea que ingresó en Sala de Medicina Interna del Hospital Enrique Cabrera, Habana, Cuba, en el mes de diciembre de 2011, con signología clínica y de laboratorio propias de la hipofunción tiroidea, siendo confirmado coma mixedematoso y con evolución desfavorable.

The follicular cells of the thyroid gland produce thyroxine and triiodothyronine hormones, as regulated by the thyrotropic hormone of the anterior pituitary, also called thyroid stimulating hormone. Myxedema coma is defined as profound hypothyroidism characterized by impairment of consciousness ranging from lethargy to stupor and coma, associated with hypothermia, hypoglycemia, seizures, hypotension, and manifestations of uncompensated hypothyroidism. The condition can be prevented if diagnosis of primary hypothyroidism is established and thyroid hormone replacement therapy is instituted. It is considered a medical emergency with high mortality rates, where environmental factors such as cold, severe infections and drug poisoning are important triggering factors. We report the case of a 74 year old male adult with no history of thyroid disease who was admitted to the Internal Medicine Ward of the “Enrique Cabrera” Hospital, Havana, Cuba, in December 2011, with clinical and laboratory signs of thyroid hypofunction. Myxedema coma was confirmed and patient course was untoward.

Encefalopatía de Wernicke y polineuropatía asociada a déficit de complejo B después de una cirugía bariátrica / Wernicke´s encephalopathy and polyneuropathy associated with vitamin B complex deficiency after a bariatric surgery

La cirugía bariátrica es un tratamiento que garantiza una pérdida de peso sustancial y duradera, y beneficios tangibles respecto a condiciones médicas asociadas a la obesidad. El aumento del número de cirugías bariátricas ha llevado también a un aumento de las complicaciones relacionadas con ella, incluyendo la encefalopatía de Wernicke y la polineuropatía por deficiencia de vitaminas del complejo B. En este artículo se reporta un caso de encefalopatía de Wernicke siete semanas después de la cirugía, enfatizando en la importancia de reconocer el espectro de la sintomatología para hacer un diagnóstico temprano, que permita intervenir en la fase reversible de esta enfermedad potencialmente letal.

Bariatric surgery is a treatment that guarantees a substantial and lasting weight loss in addition to the tangible benefits relating to obesity-associated medical conditions. The increasing number of bariatric surgeries has revealed an increasing number of complications related to this procedure, including Wernicke´s encephalopathy and vitamin B deficiency polyneuropathies. Herein, a 7-week post-surgery case of Wernicke´s encephalopathy is presented that emphasizes the importance of an early recognition of these symptoms so as to initiate intervention during the reversible phase of these potentially lethal pathologies.

Non-Traumatic Childhood Coma in Ebonyi State University Teaching Hospital; Abakaliki; South Eastern Nigeria

Background: Coma is a medical emergency; and optimal management; especially in a resource-poor setting; would depend on the knowledge of its etiology and predictors of outcome. This communication reviews the etiology and outcome of non-traumatic childhood coma in Ebonyi State University Teaching Hospital (EBSUTH); Abakaliki. Objective: To determine the incidence; etiology and outcome of non-traumatic coma in children seen at the EBSUTH; Abakaliki. Materials and Methods: This is a retrospective analysis of records of all children admitted to the children emergency ward of EBSUTH in coma of a non-traumatic origin between 1 st of January and 31 st of December; 2007. Results: Forty children presented with coma out of 673 children admitted during the study period; giving an incidence rate of 5.9. The majority of the children (62.5) were aged between 1 and 5 years of age; and 79.5of them were deeply comatose on admission. Most of the cases (85) of non-traumatic coma were due to infective causes; mainly cerebral malaria (47.5); pyogenic meningitis (17.5) and septicemia (10). Twenty-four (60) children recovered while 13 (32.5) died. Conclusion : Infections were the predominant causes of non-traumatic coma in EBSUTH. In view of the high mortality among this group of patients; efforts at the control of malaria and other infections would significantly reduce the incidence of non-traumatic coma in this study site

Facteurs de mauvais pronostic des comas non traumatiques (A propos de 449 cas observes dans le service de Reanimation Medicale du CHU.A/JRB

Justification: Le coma non traumatique traduit une alteration de la conscience survenant d'une facon spontanee; d'origine multifactorielle. C'est une urgence diagnostique et therapeutique. Le pronostic du patient comateux depend surtout de la precocite et de la qualite de la prise en charge initiale. Objectif : Cette etude essaie de determiner les facteurs de mauvais pronostic des comas non traumatiques chez 449 patients comateux; hospitalises dans le service de reanimation medicale du CHU Antananarivo/Hopital Joseph Raseta Befelatanana. Resultats : Les facteurs incrimines sont le sexe masculin; l'age avance; l'intersaison; les antecedents (alcoolisme; hypertension arterielle; accident vasculaire cerebral; broncho-pneumopathies chronique); la brutalite de l'installation du coma. D'autres parametres sont responsables des comas et aggravent le pronostic des patients : la deshydratation; l'hyperthermie superieure a 40oC; la pression arterielle tres elevee ou imprenable; la polypnee au-dela de 45cycles/min; la SpO2 basse; la tachycardie superieure a 140/min ou la bradycardie inferieure a 40/min. La decouverte de causes evidentes (hypoglycemie; pathologies vasculaires; coma ethylique complique; coma hepatique et infectieux) permet de cerner le diagnostic etiologique. Conclusion : La presence de ces facteurs de mauvais pronostic impose une prise en charge rapide et efficace afin de reduire le taux de morbi-mortalite

Culture- and antigen-negative meningitis in Guatemalan children / Meningitis negativa a pruebas antigénicas y de cultivo en niños guatemaltecos

OBJECTIVE: To compare children with confirmed bacterial meningitis (CBM) and those with culture- and latex-negative meningitis (CLN). METHODS: Children 1 to 59 months of age admitted to three major referral hospitals in Guatemala City with clinical signs compatible with bacterial infections were evaluated prospectively between 1 October 1996 and 31 December 2005. Bacterial cultures and latex agglutination antigen testing were performed on samples of cerebrospinal fluid (CSF). RESULTS: The case-fatality rate was significantly higher in the 493 children with CBM than in the 528 children with CLN (27.6 percent and 14.9 percent, respectively; P < 0.001). Children with CBM were less likely to have received antibiotics and more likely to have seizures, shock, or coma on admission than children with CLN. Among the 182 CBM survivors and 205 CLN survivors studied between October 2000 and December 2005, clinically observed sequelae were present at discharge in a higher percentage of the CBM than of the CLN group (78.6 percent and 46.8 percent, respectively; P < 0.0001). CSF glucose < 10 mg/dL, peripheral neutrophils < 2 000 cells/mm³, coma or shock at admission, and concurrent sepsis or pneumonia were risk factors for mortality in children with CBM; only coma or shock at admission predicted mortality in children with CLN. CONCLUSIONS: The high case-fatality and sequelae rates suggest that many children with CLN may have had bacterial meningitis. Estimates based on confirmed meningitis alone underestimate the true vaccine-preventable disease burden. Additional studies to determine etiologies of CLN in this population are indicated.

OBJETIVO: Comparar los casos infantiles de meningitis bacteriana confirmada (MBC) y meningitis negativa a pruebas de látex y de cultivo (MNLC). MÉTODOS: Se evaluaron los niños de 1 a 59 meses de edad ingresados en tres grandes hospitales de referencia de la Ciudad de Guatemala entre el 1 de octubre de 1996 y el 31 de diciembre de 2005 con signos clínicos de infección bacteriana. Se realizaron cultivos bacterianos y pruebas de aglutinación antigénica con látex en muestras de líquido cefalorraquídeo (LCR). RESULTADOS: La tasa de letalidad fue significativamente mayor en los 493 niños con MBC que en los 528 niños con MNLC (27,6 por ciento y 14,9 por ciento, respectivamente; P < 0,001). Los niños con MBC tuvieron menor probabilidad de recibir antibióticos y mayor de sufrir convulsiones, choques o entrar en coma al ser ingresados que los niños con MNLC. Se observó un mayor porcentaje de manifestaciones clínicas de secuelas al alta hospitalaria en los 182 niños sobrevivientes con MBC que en los 205 sobrevivientes con MNLC estudiados entre octubre de 2000 y diciembre de 2005 (78,6 por ciento y 46,8 por ciento, respectivamente; P < 0,0001). Los factores de riesgo de muerte en los niños con MBC fueron: glucosa en LCR < 10 mg/dL, neutrófilos periféricos < 2 000 células/mm³, coma o choque al ingreso, y sepsis o neumonía concurrentes; solo el coma y el choque al ingreso predijeron la muerte en niños con MNLC. CONCLUSIONES: Las altas tasas de letalidad y de secuelas indican que muchos niños con MNLC pueden haber tenido meningitis bacteriana. Las estadísticas basadas solamente en los casos confirmados de meningitis subestiman la verdadera carga de enfermedad prevenible mediante vacuna. Se deben emprender estudios adicionales para determinar las etiologías de la MNLC en esta población.

Coma criterion and classification standard of mild and moderate traumatic brain injury in rats / 法医学杂志

OBJECTIVE@#To set up a classification standard of mild and moderate traumatic brain injury, for the purpose of reliable data comparison derived from different laboratories.@*METHODS@#Traumatic brain injury (TBI) in rats was prepared by using a metallic pendulum-striker device. After injury, five variable parameters including the time of apnea and the areflexia, time of corneal reflex, external auditory canal stung reaction, body-righting reflex and needling reaction were determined and scored by using rat coma criterion. These data were judged and classified into mild and moderate head injury by brain patho-anatomy changes. Then the data were used to set up a multivariate discriminate equation.@*RESULTS@#The distinguished probability of mild and moderate TBI according to actual direct measured value and the criterion were 88.9% and 91.9%, respectively.@*CONCLUSION@#This method is able to classify mild and moderate TBI in rats.

Neurological complications in Chikungunya fever.

OBJECTIVE: The present prospective study was undertaken to study the clinical manifestations and mainly neurological complication of an acute febrile illness termed chikungunya which has recently attacked india after 43 years. METHOD: This prospective study has been conducted in hospitalised patients admitted in government and private hospitals of Kota city from August 2006 to October 2006. Patients showing neurological involvement with typical clinical picture of chikungunya infection were studied in detail and followed up for improvement and any permanent damage or death. RESULTS: Apart from typical clinical triad of high grade fever, arthralgia and rash of chikungunya infection we have observed a spectrum of neurological abnormalities in terms of altered mental functions, seizures, focal neurological deficit with abnormal CT scan of head and altered CSF biochemistry. Permanent neurological sequelae and even death has occurred. CONCLUSION: Typical clinical history of chikungunya infection, neurological complications with associated CSF abnormalities, supportive laboratory evidences, positive chikungunya IgM card test, exclusion of other causes and known predilection of arboviruses for CNS infection allows us to conclude the diagnosis of study cases as Chikungunya Encephalitis.

Cassia occidentalis poisoning causes fatal coma in children in western Uttar Pradesh.

We investigated cases of the annual seasonal outbreaks of acute hepato-myo-encephalopathy in young children in western Uttar Pradesh for causal association with Cassia occidentalis poisoning, by a prospective survey in 2006. During September-October homes of 10 consecutive cases were visited and history of eating Cassia beans was obtained in all. Nine children died within 4-5 days. There appears to be an etiological association between consumption of Cassia occidentalis beans and acute hepato-myo-encephalopathy.

Mode of death shifting from coma to syncope sports utility vehicle (SUV) accidents.

Road traffic accident is a major cause of death assuming epidemic proportion worldwide. After America, India has the largest network of roads. The total length of the road is about 33, 44,000km, out of which national highways occupies only 2% of total road length, whereas they bear 20% of the traffic load. One of the main reasons of the overcrowding of the roads is the tremendous rise in number of vehicles due to increasing distance from residence to workplace, intensive marketing campaign of newer sports utility (SUV) cars by depicting them in movies, media advertisements and easy finance availability has developed a craving to possess these sports utility vehicles in youths (both in males and females). These sports utility vehicles are nowadays becoming the rapid killer of the victims met with road traffic accidents (pedestrians, pedal cyclist and motor cyclist). The present study is based on prospective and retrospective cases of road traffic accidents involving SUV’s, since January 2005 to December 2006. The present study has shown that young adults predominantly males in their most productive year of life (21-30 years) are especially prone to road traffic trauma2. Pedestrians constitute the largest group of victims 78 cases (65%) followed by cyclist 18 cases (50%), spot death unavoidable in 83 cases (55.33%) and the thoraco-abdominal trauma found in 97 cases (80.83%)2,4. The findings of study under score the continue need for preventive strategies; aim to reduce trauma related mortality, particularly those regarding road traffic safety. The study also suggest that the large proportion of death were preventable, if underlying lesion or sequelae of injuries had been promptly addressed but unfortunately the front design of these sports utility vehicles is responsible for causing thoraco-abdominal trauma, leading to rapid death by causing haemorrhagic shock generated from involvement of the structures of thoraco-abdominal region.
