Relationship of cryptosporidiosis to abdominal pain and diarrhea in Mayan Indians

Demonstration of cryptosporidiosis in Mayan Indians living around Lake Atitlan provided an opportunity to correlate infection with abdominal pain and/or diarrhea in different age groups of children. 94 subjects experiencing abdominal pain and/or diarrhea, between the ages of 2 and 13 were studied in towns around Lake Atitlan, Guatemala, over a two-year period. Cryptosporidium oocysts were found in the feces of 29% of children who presented with abdominal pain and 21% with diarrhea. Of the 60 infected subjects, 45% were experiencing abdominal pain and 33% diarrhea, 22% had abdominal pain and diarrhea. Both abdominal pain and diarrhea were significantly higher in children under 10 years of age and were most prevalent in the 6-9 year old age group but the correlation of symptoms to infection was not significantly different as the ages of the children increased. The high frequency of abdominal pain and/or diarrhea with infection in children was consistent with cryptosporidiosis, a disease considered as one of several common intestinal infections that produce these symptoms.

Pseudoaneurisma Traumático da Aorta Abdominal. Caso Clínico

Os pseudoaneurismas da aorta abdominal são muito raros, principalmente quando associados a traumatismo abdominal fechado. Têm muitas vezes um comportamento clínico insidioso, com queixas dolorosas ou sinais compressivos de estruturas adjacentes. Os autores apresentam o caso clínico de um homem de 47 anos de idade que desenvolveu um pseudoaneurisma da aorta terminal após traumatismo abdominal fechado, na sequência de acidente de viação e que foi objecto de tratamento cirúrgico com êxito.

A 42-year-old otherwise healthy patient presented with a complaint of nine days of abdominal pain, constipation, disury, fever and right iliac fossa palpable mass. Exploratory laparotomy was performed. After surgical treatment the patient presented serious complications.

Histerectomia e Tumor Uterino: Estudo Comparativo entre Via Vaginal e Abdominal

Objectivos: Determinar a eficiência e segurança da via vaginal na patologia uterina benigna na ausência de prolapso e de contra-indicações absolutas. Material e métodos: Os autores efectuaram uma revisão das histerectomias vaginais (HV) efectuadas na ausência de prolapso urogenital (n=29). Como grupo controle foi estudado o mesmo número de histerectomias abdominais (HÁ). Resultados: Em n=29 houve 20,7% de complicações perioperatórias e pós-operatórias (via vaginal), e no grupo controle 65,5% (via abdominal). Conclusão: A via vaginal tem menor morbilidade e é mais eficiente em termos de custo operacional e benefício.

Localized Abdominal Idiopathic Lipodystrophy

Localized loss of subcutaneous tissue can occur after panniculitis, injections of corticosteroids and other drugs, or associated with infectious, autoimmune or neurologic diseases. The "idiopathic lipoatrophies" are a group of poorly characterized diseases, with focal disappearance of subcutaneous fat, and usually the thighs, abdomen or the ankles are affected. Three subtypes have been described based on clinical presentation: lipoatrophia semicircularis, annular lipoatrophy of the ankles and centrifugal lipodystrophy. We describe a 52-year-old female patient who developed a localized atrophy of the abdominal areas over a period of 3 months without any inflammatory signs over the evolution of the disease. The patient denied any previous local trauma or medication of any type. The atrophy stabilized, showing no progression over the last 6 years. The histopathological examination was normal except for the absence of subcutaneous fat, although the biopsy was taken down to the fascia. There was no clinical or serologic evidence of autoimmune diseases and laboratory testing for Borrelia burgdorferi infection was negative. Other causes of localized lipoatrophies were excluded and the final diagnosis was localized idiopathic lipodystrophy. Our patient is the second report on an abdominal lipodystrophy, with no previous inflammatory signs, absence of subcutaneous fat and no associated pathogenic factor. There is no established treatment for idiopathic lipodystrophy, and the lesions do not tend to resolve spontaneously.

Abdominal ultrasound in the evaluation of fibrosis and portal hypertension in an area of schistosomiasis low endemicity

This study was undertaken in the municipality of Bananal, São Paulo, an endemic area for schistosomiasis with a prevalence under 10% and low parasite load among infected individuals. Our objective was to identify the clinical forms of schistosomiasis among 109 patients in whom the disease had been diagnosed through direct fecal analysis and who had been medicated with oxamniquine at the time of the Plan for the Intensification of Schistosomiasis Control Actions (1998-2000). These patients were submitted to an abdominal ultrasonography and fecal analysis by Kato-Katz method, four years, on average, after the end of the Plan. Five patients, whose abdominal ultrasound images were compatible with either peripheral or central periportal fibrosis and portal hypertension, were identified. None of the 109 patients presented Schistosoma mansoni eggs at fecal analysis. Ultrasonography is a sensitive, noninvasive diagnostic method that allows a better identification of the extent of liver involvement in schistosomiasis cases.

Effects of Aerobic Exercise Associated with Abdominal Microcurrent: A Preliminary Study

Objective: To analyze the short- and long-term effects of microcurrent used with aerobic exercise on abdominal fat (visceral and subcutaneous). Methods: Forty-two female students from a university population were randomly assigned into five group: intervention group (IG) 1 (n=9), IG2 (n=9), IG3 (n=7), IG4 (n=8), and placebo group (PG) (n=9). An intervention program of 10 sessions encompassing microcurrent and aerobic exercise (performed with a cycloergometer) was applied in all groups, with slightly differences between them. In IG1 and IG2, microcurrent with transcutaneous electrodes was applied, with different frequency values; 30-minute exercise on the cycloergometer was subsequently performed. IG3 used the same protocol as IG1 but with different electrodes (percutaneous), while in IG4 the microcurrent was applied simultaneously with the cycloergometer exercise. Finally, the PG used the IG1 protocol but with the microcurrent device switched off. All groups were evaluated through ultrasound and abdominal perimeter measurement for visceral and subcutaneous abdominal fat assessment; through calipers for skinfolds measurement; through bioimpedance to evaluate weight, fat mass percentage, and muscular mass; and through blood analyses to measure cholesterol, triglyceride, and glucose levels. Results: After intervention sessions, visceral fat decreased significantly in IG1 compared with the PG. Subcutaneous fat was reduced significantly in all groups compared with the PG. After 4 weeks, almost all results were maintained. Conclusion: The addition of microcurrent to aerobic exercise may reduce fat more than does aerobic exercise alone.

Effects of microcurrents and physical exercise on the abdominal fat in patients with coronary artery disease

Introduction Coronary artery disease is associated with decreased levels of physical activity, contributing to increases in abdominal fat and consequently increasing metabolic risk. The innovative use of microcurrents may be an effective method to increase the lipolytic rate of abdominal adipocytes. This study aimed to investigate the effects of utilizing microcurrents in a home-based exercise program in subjects with coronary artery disease to assess changes in total, subcutaneous and visceral abdominal adipose tissue. Methods This controlled trial included 44 subjects with myocardial infarction, randomly divided into Intervention Group 1 (IG1; n = 16), Intervention Group 2 (IG2; n = 12) and Control Group (CG; n = 16). IG1 performed a specific exercise program at home during 8 weeks, and IG2 additionally used microcurrents on the abdominal region before the exercise program. All groups were given health education sessions. Computed tomography was used to evaluate abdominal, subcutaneous and visceral fat, accelerometers to measure habitual physical activity and the semi-quantitative food frequency questionnaire for dietary intake. Results After 8 weeks, IG2 showed a significantly decrease in subcutaneous fat (p ≤ 0.05) when compared to CG. Concerning visceral fat, both intervention groups showed a significant decrease in comparison to the CG (p ≤ 0.05). No significant changes were found between groups on dietary intake and habitual physical activity, except for sedentary activity that decreased significantly for IG2 in comparison with CG (p ≤ 0.05). Conclusion This specific home-based exercise program using microcurrent therapy for individuals with coronary artery disease showed improvements in visceral and subcutaneous abdominal fat.

Abdominal angiostrongyliasis: report of two cases with different clinical presentations

Abdominal angiostrongyliasis is a sporadic infectious disease caused by the nematode Angiostrongylus costaricensis. It usually presents as acute abdomen, secondary to mesenteric ischemia, and pronounced eosinophilia. In some cases its course is insidious and transient, and the diagnosis is suspicious. The disease is confirmed by the detection of A. costaricensis elements in surgical specimen. The treatment is supportive, with avoidance of antihelminthic administration due to a possible erratic migration followed by worsening of the disease. We report two cases, both with intense eosinophilia and serum IgG-ELISA positive to A. costaricensis. The first case presented ileal perforation and was surgically treated. The second one showed hepatic nodules at ultrasound and was only symptomatically treated, evolving to an apparent protracted resolution. These two cases exemplify different clinical forms of the disease, one of them with liver involvement.

Influence of cardiorespiratory fitness and parental lifestyle on adolescents' abdominal obesity

The aims of this study were (1) to analyse the influence of cardiorespiratory fitness (CRF) and parental overweight status (POS) and socioeconomic status (SES) on abdominal obesity. This study was comprised of 779 adolescents (12-18 years). Waist-height ratio (WHtR), 20 m shuttle-run test to ascertain CRF, POS according to World Health Organization recommendations and SES of parents using level of education were analysed. Using WHtR, the prevalence of abdominal obesity was 21.3% (23.5% girls and 17.9% boys; p = 0.062). Regardless of gender, participants who belonged to the WHtR risk group had significantly (p ≤ 0.05) lower CRF scores than the WHtR non-risk group; 84.4% of girls who belonged to the WHtR risk group had one or two overweight parents (p ≤ 0.05). Boys with low CRF (OR: 6.43; CI: 3.33-12.39) were more likely to belong to the WHtR risk group compared with their lean peers. Girls with low CRF (OR: 1.78; CI: 1.14-2.78) and with at least one overweight parent (OR: 2.50; CI: 1.07-5.85) or two overweight parents (OR: 4.90; CI: 2.08-11.54) were associated with the risk of abdominal obesity. This study highlights the influence of adolescents' family on abdominal obesity, especially in girls. Further, the data suggested that low CRF was a strong predictor of risk values of abdominal obesity in adolescence.

Abdominal angiostrongyliasis with involvement of liver histopathologically confirmed: a case report

Human abdominal angiostrongyliasis is a zoonotic disease caused by ingestion of the L3 larvae of Angiostrongylus costaricensis. The human infection gives rise to a pathological condition characterized by acute abdominal pain, secondary to an inflammatory granulomatous reaction, marked eosinophilia and eosinophilic vasculitis. Most commonly this disease is limited to intestinal location, primary ileocecal, affecting the mesenteric arterial branches and intestinal walls. We present one of the few cases reported around the world with simultaneous involvement of the intestines and liver, including proved presence of nematodes inside the hepatic arteriole.

Influência da atividade muscular abdominal na velocidade do oi tsuki

Introdução: No karaté a região lombo pélvica é importante, pois permite dar estabilidade e potenciar a força produzida na aplicação de técnicas de karaté. Apesar disso, nenhum estudo estuda a influência da atividade muscular abdominal na velocidade de aplicação de técnicas. Existem diversos estudos sobre o karaté mas nenhum deles foca a importância da atividade muscular abdominal. Objetivo: O objetivo deste estudo é verificar se o timing e a magnitude de ativação dos músculos abdominais influenciam a velocidade aplicada na técnica de karaté oi tsuki. Metodologia: Estudo transversal analítico com 7 praticantes de karaté do sexo masculino com graduação de 3º kyu (1º nível de cinturão castanho) ou superior. Foi avaliado o timing e a magnitude de ativação muscular abdominal com eletromiografia de superfície e a velocidade de movimento com sistema Qualisys, durante a execução do oi tsuki. Para dados estatísticos realizou-se o teste de spearman (nível de significância de 0,05) para testar correlação entre timing e a velocidade e entre magnitude de ativação e a velocidade, recorrendo ao coeficiente de determinação para verificar o grau de correlação. Para verificar diferenças bilaterais entre os timings e a magnitude de ativação dos músculos abdominais realizou-se o teste de Wilcoxon (nível de significância de 0,05). Resultados: Foi observada uma relação estatisticamente significativa (p< 0,05) entre o timing de ativação dos músculos transversos/oblíquos internos abdominais e do oblíquo externo contra lateral com a velocidade média do oi tsuki. Os timings de ativação dos músculos retos abdominais e oblíquo externo ipsilateral não revelaram valores de significância (p> 0,05) que possibilitem afirmar que existe relação entre esses timings e a velocidade média do oi tsuki. Não existem valores estatisticamente significativos (p> 0,05) para afirmar que existe relação entre a magnitude de ativação dos músculos abdominais e a velocidade média do oi tsuki. A velocidade máxima do movimento não foi afetada nem pelos timings de ativação dos músculos do abdómen, nem pelas suas magnitudes de ativação. Apenas o timing entre os músculos Transversos/oblíquos internos contra lateral e ipsilateral revelou diferenças. Conclusão: O tronco evidencia ser importante para a prática do karaté, não só pela melhoria da performance, mas também pela melhoria de estabilidade e consequente técnica. Apresenta uma aparente melhoria na velocidade inicial da técnica, podendo afetar positivamente a performance. Para além da performance, contribui para a segurança das estruturas lombo pélvicas, promovendo um menor risco de lesão.

Association of Intestinal Malrotation and Bochdalek Hernia in an Adult: a Case Report

Background Late presentations of congenital diaphragmatic hernia are rare and differ from the classic neonatal presentation. The association with other congenital malformations in children, mainly intestinal malrotation, is well documented. The diagnosis of this association in adults is very rare, and depends on a high degree of suspicion. Case presentation We report a case of a 50-year-old female Caucasian patient with a previous history of intestinal malrotation diagnosed in adolescence and treated conservatively. She was referred to the hospital with signs and symptoms of intestinal obstruction. The patient undertook computed tomography that confirmed small bowel obstruction with no obvious cause, and a right subphrenic abscess with right empyema was also present. An exploratory laparotomy was performed that revealed an intestinal malrotation associated with a right gangrenous and perforated Bochdalek hernia. Resection of the affected small bowel, closure of the Bochdalek foramen and the Ladd procedure were carried out. Conclusion This case shows a rare association of two rare conditions in adults, and highlights the challenge in reaching the diagnosis and management options.
