Obesity is associated with a reduced odds for blunt intra-abdominal injuries in children.

OBJECTIVES: Children with obesity may possess unique injury characteristics that may affect their emergency care. To better understand this relationship, we investigated the association of obesity in pediatric trauma patients and intra-abdominal injuries (IAIs) and routinely utilized emergency department (ED) diagnostic procedures (computed tomography (CT) scans and ultrasound (US) examinations). METHODS: This secondary data analysis utilized Pediatric Emergency Care Applied Research Network (PECARN) data from 2007 to 2010. Since height data were not available, children (2-17 years) with obesity were defined using weight-for-age percentiles. Non-parametric testing determined potential confounders. Adjusted odds ratios (aOR) were calculated using binary logistic regression for weight status and IAIs and diagnostic procedures. RESULTS: There were 3846 patients with actual weight recorded: 3301 (85.8%) children without obesity and 545 (14.2%) with obesity. Children with obesity had decreased odds for IAI after adjusting for race, mechanical force injury (MFI) type, vomiting, and abdominal wall trauma (adjusted odds ratio (aOR)=0.58 (95% CI 0.35-0.97); p-value=0.04). Patients with obesity had reduced odds for a CT examination. No association was found between obesity status and US utilization. African-American patients had decreased odds for IAIs, CT scans and US examinations after adjustment which could be related to MFI type. CONCLUSIONS: Obesity appears to reduce the odds for pediatric IAIs and CT scans, but not for US examinations. Selection bias is possible due to injury severity and missing or excluded weight data. Further research is needed in other pediatric populations with obesity and blunt injuries.

Acute Surgical Decision-Making in Abdominal Trauma Is Not Altered by Race or Socioeconomic Status.

Two main procedures are performed on patients suffering from colonic perforation, diverting colostomy and primary tissue repair. We investigated patient race, ethnicity, and socioeconomic status (SES) that predicted surgical outcomes after blunt or penetrating trauma. A retrospective analysis was performed using data from the National Trauma Data Bank for three years (2013-2015). We identified patients who presented with primary colonic injury and subsequent colon operation (n = 5431). Operations were grouped into three classes: colostomy, ileostomy, and nonostomy. Multiple linear and logistic regressions were performed to assess how race and insurance status are associated with the primary outcome of interest (ostomy formation) and secondary outcomes such as length of stay, time spent in ICU, and surgical site infection. Neither race/ethnicity nor insurance status proved to be reliable predictors for the formation of an ostomy. Patients who received either a colostomy or ileostomy were likely to have longer stays (OR [odds ratio]: 5.28; 95% CI [confidence interval]: 3.88-6.69) (OR: 11.24; 95% CI: 8.53-13.95), more time spent in ICU (2.73; 1.70-3.76) (7.98; 6.10-9.87), and increased risk for surgical site infection (1.32; 1.03-1.68) (2.54; 1.71-3.78). Race/ethnicity and SES were not reliable predictors for surgical decision-making on the formation of an ostomy after blunt and penetrating colonic injury. However, the severity of the injury as calculated by Injury Severity Score and the number of abdominal injuries were both associated with higher rates of colostomy and ileostomy. These data suggest that surgical decision-making is dependent on perioperative patient presentation and, not on race, ethnicity, or SES.

Frequency and clinical features of patients who attempted suicide by Hara-Kiri in Japan.

Hara-kiri is a unique Japanese custom, primarily stemming from the manners and customs that a samurai held. The aim of the present study was to investigate the clinical features of individuals who attempted suicide by hara-kiri. We enrolled 647 patients who had attempted suicide. Clinical features were compared between those who had employed hara-kiri and those who had used other methods. 25 of the 647 subjects had attempted suicide by hara-kiri. The ratio of men to women and the proportion of patients with mood disorders were significantly higher in the hara-kiri group than in the other methods group. The average length of stay in either the hospital or in the intensive care unit was also longer in the hara-kiri group than in the other methods group. Hara-kiri is an original Japanese method of attempting suicide, and suicide attempts by hara-kiri may be aimed at maintaining a reputation or taking responsibility.

Assault induced stab injuries: epidemiology and actual treatment strategy.

OBJECTIVES: To investigate and analyse epidemiology, demographics and patterns of presentation of assault induced stab injuries in a main Belgian trauma centre. To evaluate surgical management, complications and postoperative follow-up of the stab wound victims. METHODS: One hundred and seventy assaulted patients, hospitalised because of stab injuries from January 2000 to June 2007 are studied retrospectively. RESULTS: Ninety-five percent of the assaults occurred on men and the mean age of the patients was 31.1 +/- 9.7 years. Ethnic minorities represent 77% of the patients hospitalised for assaults and 26.5% of all patients proved to be under toxic influence, predominantly from alcohol (21.8%). A decline of admissions of patients with stab injuries during the period 2002-2004 is recorded. However, the incidence doubled in the next two-year period. A weekend peak and circadian rhythm is apparent with more than 20% of the patients admitted between 4 and 6 am. The trunk is most frequently stabbed (54.5%) resulting in a laparotomy rate of 51%. One third of the patients who underwent thoraco-abdominal surgery revealed diaphragmatic injuries. Seventy-five percent of the patients left the hospital in a good condition while 2.4% had neuromuscular lesions. Two patients had serious vascular complications during follow-up. During the study period, no mortality was recorded. CONCLUSIONS: Stab wounds were recorded mainly in young and middle-aged men from ethnic minorities, whereas almost 27% were under the influence of drugs. A conservative approach was generally used resulting in a low laparotomy and thoracotomy rate without affecting mortality. Neuromuscular lesions are important long-term complications of stab injuries.

Contribuição da ultra-sonografia abdominal no seguimento de pacientes pós-tratamento de câncer mamário / Contribution of abdominal ultrasound in breast cancer post-treatment follow-up

OBJETIVO: Avaliar a contribuição da ultra-sonografia abdominal em um grupo de pacientes em seguimento pós-tratamento de câncer primário da mama. MATERIAL E MÉTODOS: Foram analisados, retrospectivamente, os resultados dos exames ecográficos abdominais em 100 prontuários de pacientes tratadas de câncer primário da mama, realizados de janeiro a dezembro de 1997, no Setor de Ultra-sonografia da Divisão de Radiologia do Departamento de Clínica Médica da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo. Informações como idade, tipo histológico, estadiamento, número e resultados dos exames ultra-sonográficos foram tabelados e analisados. RESULTADOS: Em 70 por cento dos casos os laudos ecográficos abdominais eram normais. O diagnóstico de metástase hepática foi de 3 por cento. CONCLUSÃO: O maior porcentual de alterações encontradas não estava relacionado diretamente como complicação do câncer mamário

OBJECTIVE: To evaluate the contribution of abdominal ultrasound in the follow-up of a group of post-treatment breast cancer patients. MATERIAL AND METHODS: We retrospectively studied the findings of abdominal ultrasound examinations of 100 patients treated for primary breast cancer. These patients were attended from January to December of 1997 at the Ultrasound Sector, Division of Radiology of the Department of Clinical Medicine of the "Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo", SP, Brazil. Information such as age, histological type, staging, number of examinations and ultrasound findings were rated and analyzed. RESULTS: Abdominal ultrasound was normal in 70% of the patients whereas liver metastases were diagnosed in 3% of the patients. CONCLUSION: The majority of the abnormalities identified were not directly related to complications of breast cancer.
