Urgent capsule endoscopy is useful in severe obscure-overt gastrointestinal bleeding

AIM: With capsule endoscopy (CE) it is possible to examine the entire small bowel. The present study assessed the diagnostic yield of CE in severe obscure-overt gastrointestinal bleeding (OOGIB). METHODS: During a 3-year period, 15 capsule examinations (4.5% of all CE in a single institution) were carried out in 15 patients (11 men; mean age 69.9 +/- 20.1 years) with severe ongoing bleeding, defined as persistent melena and/or hematochezia, with hemodynamic instability and the need for significant red blood cell transfusion. CE was carried out after non-diagnostic standard upper and lower endoscopy. The mean time from admission until CE was 4.1 +/- 4.4 days (0-15 days). RESULTS: CE revealed active bleeding in seven patients and signs of recent bleeding in four. Etiology of bleeding was correctly diagnosed in 11 patients (73.3%) (portal hypertension enteropathy, three patients; subepithelial ulcerated lesion, two patients; angiodysplasia, two patients; jejunal ulcer with visible vessel, one patient; multiple small bowel ulcers, one patient; jejunal tumor, one patient; jejunal mucosa irregularity with adherent clot, one patient). One patient (6.7%) had active bleeding but no visible lesion. As a consequence of the capsule findings, specific therapeutic measures were undertaken in 11 patients (73.3%) with five managed conservatively, four endoscopically and two surgically. Two patients experienced bleeding recurrence. One of them, with a probable small bowel tumor, refused any other interventions. CONCLUSIONS: CE is useful in patients with severe OOGIB by providing positive findings in the majority of patients, with subsequent impact on therapeutic procedures

Effect of portal hypertension in the small bowel: an endoscopic approach

BACKGROUND AND AIM: The effects of portal hypertension in the small bowel are largely unknown. The aim of the study was to prospectively assess portal hypertension manifestations in the small bowel. METHODS: We compared, by performing enteroscopy with capsule endoscopy, the endoscopic findings of 36 patients with portal hypertension, 25 cirrhotic and 11 non-cirrhotic, with 30 controls. RESULTS: Varices, defined as distended, tortuous, or saccular veins, and areas of mucosa with a reticulate pattern were significantly more frequent in patients with PTH. These two findings were detected in 26 of the 66 patients (39%), 25 from the group with PTH (69%) and one from the control group (3%) (P < 0.0001). Among the 25 patients with PTH exhibiting these patterns, 17 were cirrhotic and 8 were non-cirrhotic (P = 0.551). The presence of these endoscopic changes was not related to age, gender, presence of cirrhosis, esophageal or gastric varices, portal hypertensive gastropathy, portal hypertensive colopathy, prior esophageal endoscopic treatment, current administration of beta-blockers, or Child-Pugh Class C. More patients with these endoscopic patterns had a previous history of acute digestive bleeding (72% vs. 36%) (P = 0.05). Active bleeding was found in two patients (5.5%). CONCLUSIONS: The presence of varices or areas of mucosa with a reticulate pattern are manifestations of portal hypertension in the small bowel, found in both cirrhotic and non-cirrhotic patients. The clinical implications of these findings, as regards digestive bleeding, are uncertain, although we documented acute bleeding from the small bowel in two patients (5.5%)

Capsule endoscopy in inflammatory bowel disease type unclassified and indeterminate colitis serologically negative

BACKGROUND: The value of capsule endoscopy in the setting of inflammatory bowel disease type unclassified (IBDU) and indeterminate colitis (IC) remains obscure. The aim was to evaluate the clinical impact of capsule endoscopy on IBDU/IC patients with negative serology. METHODS: Eighteen patients with long-standing IBDU (n = 14) and IC (n = 4) were enrolled to undergo a capsule endoscopy and then followed prospectively. Lesions considered diagnostic of Crohn's disease (CD) were 4 or more erosions/ulcers and/or a stricture. The median follow-up time after capsule endoscopy was 32 ± 11 months (23-54 months). RESULTS: Total enteroscopy was possible in all patients. In 2 patients the examination was normal (Group 1). In 9 patients subtle findings were observed (Group 2): focal villi denudation (n = 1) and fewer than 4 erosions/ulcers (n = 8). In 7 patients, 4 or more erosions/ulcers were detected (Group 3), leading to a diagnosis of CD. However, their treatment was not reassessed on the basis of the capsule findings. Until now, a definitive diagnosis has been achieved in 2 additional patients: 1 from Group 1 (ulcerative colitis) and another patient from Group 2 (CD), who began infliximab infusions. Nine patients remained indeterminate at follow-up. CONCLUSIONS: Although capsule endoscopy enabled the diagnosis of CD in 7 patients, in none of them was the clinical management changed. Moreover, a change in therapy due to a diagnosis of CD was made for only 1 patient, who presented nonspecific findings. Our results suggest that capsule findings are not helpful in the work-up of these patient

Small bowel pseudomelanosis and oral iron therapy

Small bowel pseudomelanosis is a rarely reported clinical entity characterized by brown pigmentation of small bowel mucosa. The authors describe two cases, both with iron deficiency anemia, one of an 81-year-old female patient submitted for capsule endoscopy that revealed a brown pigmentation of all small bowel mucosa and another of an 81-year-old male whose retrograde double-balloon enteroscopy revealed a diffuse brown pattern of small bowel mucosa. Ileal biopsies confirmed intense iron deposition in the macrophages of the lamina propria. Both patients were on oral iron therapy and the second one had a previous double-balloon enteroscopy, 2 years earlier, which revealed only ileal angiodysplasias. These two cases demonstrate the importance of two new endoscopic methods for diagnosis of small bowel pseudomelanosis, the rarity of such an entity and its close relation with oral iron therapy

Pediatria do Neurodesenvolvimento. Levantamento Nacional de Recursos e Necessidades

As perturbações do neurodesenvolvimento são das patologias crónicas mais frequentes da infância e com tendência a aumentar nas sociedades modernas. Têm na grande maioria dos casos um percurso crónico e com limitação da aprendizagem necessária para a integração na sociedade de um modo autónomo. A Sociedade de Pediatria do Neurodesenvolvimento da Sociedade Portuguesa de Pediatria procedeu em 2008 e 2009 ao levantamento de recursos, movimento e necessidades na área assistencial do neurodesenvolvimento no universo de 49 hospitais portugueses com Pediatria, referente a 31 de Dezembro de 2007. Responderam 42 (85.7%) hospitais. O número total de consultas de desenvolvimento representou 10.7% das de Pediatria, e foi- -lhe imputada uma mediana de tempo de 20 horas por semana. Dedicavam-se ao desenvolvimento 82 pediatras, mas mais de dois terços só o fazia a tempo parcial. Outros profissionais (fisiatras, psicólogos, terapeutas da fala, terapeutas ocupacionais, fisioterapeutas, docentes e técnicos de Serviço Social) faziam parte das equipas do desenvolvimento, mas em menor número que os pediatras, e de igual modo só raramente a tempo completo. Aguardava por consulta de desenvolvimento uma mediana de 185 crianças, e o tempo de espera variou entre um e 18 meses(mediana de seis). No seu conjunto os hospitais a curto prazo recrutariam 34 Pediatras para se dedicarem à área do neurodesenvolvimento,metade em regime de tempo completo. Dos outros profissionais requisitados [psicólogos (21), terapeutas da fala (20), docentes (20), terapeutas ocupacionais (14), fisioterapeutas (8) e técnicos do Serviço Social (6)], solicitavam-nos a tempo inteiro. Concluí-se que o movimento assistencial específico desta área no contexto global da Pediatria representa já um número significativo de consultas. Ainda assim, a resposta na área do neurodesenvolvimento revelou-se insuficiente e as equipas não funcionavam na generalidade em trabalho multidisciplinar. Contudo, os pedidos solicitados de recursos humanos médicos e não médicos e a preferência de que a dedicação ao neurodesenvolvimento fosse a tempo completo reflecte uma evolução positiva a curto prazo, caso estes recrutamentos se venham a concretizar

Endoscopic treatment of bleeding gastric varices with histoacryl (N-butyl-2-cyanoacrylate): a South European single center experience

BACKGROUND: Endoscopic injection of N-butyl-2-cyanoacrylate is the current recommended treatment for gastric variceal bleeding. Despite the extensive worldwide use, there are still differences related to the technique, safety, and long term-results. We retrospectively evaluated the efficacy and safety of cyanoacrylate in patients with gastric variceal bleeding. PATIENTS AND METHODS: Between January 1998 and January 2010, 97 patients with gastric variceal bleeding underwent endoscopic treatment with a mixture of N-butyl-2-cyanoacrylate and Lipiodol(TM). Ninety-one patients had cirrhosis and 6 had non-cirrhotic portal hypertension. Child-Pugh score at presentation for cirrhotic patients was A-12.1 %; B-53.8 %; C-34.1 % and median MELD score at admission was 13 (3-26). Successful hemostasis, rebleeding rate and complications were reviewed. Median time of follow up was 19 months (0.5-126). RESULTS: A median mixture volume of 1.5 mL (0.6 to 5 mL), in 1 to 8 injections, was used, with immediate hemostasis rate of 95.9 % and early rebleeding rate of 14.4 %. One or more complications occurred in 17.5 % and were associated with the use of Sengstaken-Blakemore tube before cyanoacrylate and very early rebleeding (p < 0.05). Hospital mortality rate during initial bleeding episode was 9.3 %. Very early rebleeding was a strong and independent predictor for in-hospital mortality (p < 0.001). Long-term mortality rate was 58.8 %, in most of the cases secondary to hepatic failure. CONCLUSION: N-butyl-2-cyanoacrylate is a rapid, easy and highly effective modality for immediate hemostasis of gastric variceal bleeding with an acceptable rebleeding rate. Patients with very early rebleeding are at higher risk of death

Neonatal morbidity and outcome of live born premature babies after attempted illegal abortion with misoprostol.

Misoprostol is a synthetic prostaglandin currently employed to induce labor. Association with illegal abortion has been reported; however, neonatal outcome and morbidity after a failed attempt of abortion has not been described. OBJECTIVES: To report the association between misoprostol self-medication and preterm labor and to assess perinatal risk factors, morbidity and early outcomes. METHODS: We conducted a prospective study of all very low birth weight (VLBW) infants delivered in Hospital Fernando Fonseca, during a 5-year period. VLBW infants were assigned to misoprostol group (MG) when preterm delivery was attributed to misoprostol and matched with newborns with similar gestational age, birth- weight, and gender. RESULTS: During the study period 311 VLBW infants were born. Nineteen belonged to misoprostol group (MG) and 58 were selected for controls. Mothers from MG were significantly younger (21.5 vs 27.5, p = 0.001) and from African origin (74 vs 31%, p = 0.006), had significantly less prenatal care (21 vs 67%, p = 0.000), less antenatal steroids (5 vs 50%, p = 0.001), and were delivered less often by C-section (11 vs 60%, p = 0.000). MG infants had significantly higher rates of patent ductus arteriosus (58 vs 29%, p = 0.031) and chronic lung disease (47 vs 14%, p = 0.026). Mortality rate at 3 months was similar in both groups, but the incidence of abnormal neurodevelopment at 1 year of age was significantly higher in the MG (50 vs 16%, p= 0.02)

Doença de Kawasaki: casuística do Hospital Fernando da Fonseca

Introdução: A doença de Kawasaki (DK) é a doença cardíaca adquirida mais importante da infância, em países desenvolvidos. Vinte por cento das crianças não tratadas desenvolvem doença das coronárias, sendo as complicações a nível cardiovascular que determinam a morbilidade e mortalidade da doença. Objectivo: Avaliar a epidemiologia, clínica e alterações laboratoriais e ecocardiográficas dos casos de DK diagnosticados no H. Fernando Fonseca e identificar os eventuais factores que possam influenciar o prognóstico da doença. População e Métodos: Estudo retrospectivo, Junho 1996 a Dezembro de 2003, das crianças internadas no Hospital Fernando Fonseca com Doença Kawasaki. O diagnóstico baseou-se na presença de febre associada a 4 dos 5 critérios clássicos ou 3 deles em associação com aneurismas coronários. Analisaram-se parâmetros demográficos, clínica, exames complementares, terapêutica e evolução. A análise estatística foi realizada em SPSS, utilizando os testes de Mann-whitney e Teste Exacto de Fisher. Resultados: Registaram-se 23 crianças com DK. A incidência foi de 8,2 por 100 000 crianças < 5 anos. A idade variou entre os 6 meses e os 5 anos (mediana - 20 meses) Vinte e uma (91 %) tinham < 5 anos, dos quais 13 tinham < 2 anos. Houve um predomínio do sexo masculino (74 %) e da raça caucasiana (83 %). Nove casos residiam na mesma área geográfica. Foi documentada patologia infecciosa concomitante em 10 (43%)crianças (Parvovirus, Chlamydia pneumoniae, Vírus sincicial respiratório, Enterovirus e Herpes vírus 6). Vinte crianças preenchiam os critérios de DK clássica. Em 22 crianças foi administrada terapêutica combinada com aspirina e imunoglobulina endovenosa, em média foi administrada ao 7.º dia de doença. Sete (30 %) crianças apresentaram envolvimento das artérias coronárias. A idade inferior a 2 anos foi significativa para a lesão coronária. O tempo médio de seguimento foi de 16 meses. Não se registou mortalidade e actualmente apenas uma criança mantém aneurisma. Conclusões: O risco de lesões cardíacas associou-se à idade inferior a 2 anos, como descrito em outras séries. A origem geográfica em comum e a presença de diversos agentes infecciosos, pode indiciar, a importância da causa infecciosa como desencadeadora do processo
