RESUMO

BACKGROUND: For patients requiring colonoscopy while admitted to hospital, achieving adequate cleansing of the colon is often difficult. OBJECTIVES: To assess the impact of patient education, in the form of both counselling and written instructions, on bowel cleanliness at colonoscopy. METHODS: A total of 38 inpatients at a tertiary care hospital in Vancouver, British Columbia, who were referred to the gastroenterology service for colonoscopy were enrolled in the present study. Sixteen patients were randomly assigned to the intervention group, while 22 patients comprised the control group. Both groups received a clear liquid diet and 4 L of a commercially available bowel preparation. The intervention group also received a brief counselling session and written instructions outlining the methods and rationale for bowel preparation before colonoscopy. Bowel cleanliness was assessed by the endoscopist using a five-point rating scale. RESULTS: The two groups were similar with respect to demographics, the indication for colonoscopy and findings at colonoscopy. The median bowel cleanliness scores in the control group and the enhanced-instruction group were 3.0 and 2.0, respectively (P=0.001). CONCLUSION: Patient counselling and written instructions are inexpensive, safe and simple interventions. Such interventions are an effective means of optimizing colonoscopy preparation in the inpatient setting.

RESUMO

BACKGROUND: Patients who receive liver transplantation for chronic hepatitis B infection require long-term combination therapy with hepatitis B immunoglobulin (HBIG) and oral antiviral medication to prophylax against graft re-infection. This study examines the efficacy and patient preference of subcutaneous (SC) administration of HBIG in maintaining anti HBs titres > 100 IU/L. MATERIALS AND METHODS: 12 patients who were stable while receiving our standard IM HBIG protocol received an alternate formulation by SC injection, consisting of 10 mL (3120 IU) HBIG as 4 x 2.5 mL SC injections. SC injection were repeated as soon as titres reached 100-150 IU/mL during the 3 month study period. A questionnaire was administered upon study entry and exit to subjectively assess patient preference. RESULTS: Anti- HBs Cmax after first injection was 441.6 IU/L +/- 81.5, and Tmax was 7.1 +/- 3.2 days. SC injections were required every 56 days, which compared well to the frequency of required IM injections prior to study enrollment of 45 days. The patients mean ratings of pain on a 0-10 scale were 5 for the IM route and 1.6 for the SC route. All patients preferred the SC injections to the IM. CONCLUSION: SC administration of HBIG can effectively maintain anti HBs levels above the requisite 100 IU/L while substantially decreasing patient discomfort and improving patient satisfaction, and therefore becomes a very attractive alternative to IM HBIG injections. Further studies and wider use of SC HBIG based on this study may alter the standard practice of transplantation centers

RESUMO

Much about the etiology, pathophysiology, natural course and optimal treatment of cystic disease of the biliary tree remains under debate. Gastroenterologists, surgeons and radiologists alike still strive to optimize their roles in the management of choledochal cysts. To that end, much has been written about this disease entity, and the purpose of this 3-part review is to organize the available literature and present the various theories currently argued by the experts. In part 3, we discuss the management of choledochal cysts, thus completing our comprehensive review.

RESUMO

Familial hypobetalipoproteinemia (FHBL) is a rare genetic disorder of lipid metabolism that is associated with abnormally low serum levels of low-density lipoprotein (LDL) cholesterol and apolipoprotein B. It is an autosomal co-dominant disorder, and depending on zygosity, the clinical manifestations may vary from none to neurological, endocrine, hematological or liver dysfunction. Nonalcoholic fatty liver disease is common in persons with FHBL, however progression to nonalcoholic steatohepatitis is unusual. We describe here a patient with a novel APOB mutation, V703I, which appears to contribute to the severity of the FHBL phenotype. He had liver enzyme abnormalities, increased echogenicity of the liver consistent with steatosis, very low LDL cholesterol at 0.24 mmol/l (normal 1.8-3.5 mmol/l) and an extremely low apolipoprotein B level of 0.16 g/l (normal 0.6-1.2 g/l). APOB gene sequencing revealed him to be a compound heterozygote with two mutations (R463W and V703I). APOB R463W has previously been reported to cause FHBL. Genetic sequencing of his first-degree relatives identified the APOB V703I mutation in his normolipidemic brother and father and the APOB R463W mutation in his mother and sister, both of whom have very low LDL cholesterol levels. These results suggest that the APOB V703I mutation alone does not cause the FHBL phenotype. However, it is possible that it has a contributory role to a more aggressive phenotype in the presence of APOB R463W.

RESUMO

BACKGROUND: Choledochal cysts are dilations of the biliary tree. Although commonly reported in Asian populations, the incidence outside of Asia is as low as 1:150 000. The largest series of patients with choledochal cyst disease outside of Asia is this one, studying 70 patients treated in Vancouver between 1971 and 2003. PATIENTS AND METHODS: This was a retrospective chart review. RESULTS: In all, 19 paediatric and 51 adult patients were evaluated; 21% of paediatric and 25% of adult patients were Asian. All paediatric patients had type I or IV cysts, whereas adult patients represented the different subtypes. Abdominal pain was the presenting symptom in 79% of children and 88% of adults, vomiting was present in 42% of children and 63% of adults and jaundice was seen in 31.5% of children and 39% of adults. Ultrasound was used in 94.7% of children, and ERCP in 80% of adults. In all, 84% of paediatric patients, 100% of adult patients with type I cysts and 85.7% of adult patients with type IV cysts received complete cyst excision and Roux-en-Y hepaticojejunostomy. Complications in both groups were low. CONCLUSIONS: Although Vancouver does have a large Asian population, this does not explain how common choledochal cysts are in this city. Although some authors argue that paediatric and adult disease are caused by different aetiologies, presentation patterns in our study between the two groups were very similar. We recommend complete cyst excision and Roux-en-Y hepaticojejunostomy as the surgery of choice, and advocate early surgery after diagnosis to promote ease of surgery and prevention of future complications.

RESUMO

Möbius syndrome is classically defined as combined congenital bilateral facial and abducens nerve palsies, although it may also be associated with a myriad of other craniofacial, musculoskeletal, cardiothoracic, endocrinologic, and developmental disorders. The problem that most patients complain about, however, is the inability to smile and close their lips while eating. Although the etiology of this syndrome is still unknown, scientific support has been growing for the hypothesis that it is due to an embryological disruption of subclavian artery development. The treatment of choice for facial reanimation in these patients is a neurovascular free muscle transfer, ideally using the gracilis muscle with direct repair of the gracilis muscle's motor nerve to the masseteric branch of the trigeminal nerve. If the masseteric nerve is unavailable, a partial hypoglossal or accessory nerve may be used. These operations, enhanced by the effects of cerebral plasticity, may allow Möbius patients to reach their goals of satisfactory spontaneous smiles.

RESUMO

Excessive tension across a nerve repair is known to impair nerve regeneration. However, it is uncertain whether nerve grafting is necessary when end-to-end repair would result in only mild to moderate tension. This study investigated the effect of tension on nerve regeneration. Sciatic nerves of 48 Lewis rats were transected and then repaired primarily after resection of 0-, 3-, 6-, or 9-mm lengths of nerve. Postoperative tension levels were quantified using a tensometer. Robust nerve regeneration was observed at 4 weeks in all except the 9-mm repair group, which showed lower nerve fiber counts, percent neural tissue, and nerve density (P < 0.05) and decreased functional recovery. These data indicate that modest levels of tension are well tolerated, but nerve regeneration drops precipitously once a critical tension threshold is exceeded. This threshold was between 0.39 and 0.56 N in the model studied, corresponding to a nerve defect between 6 mm and 9 mm.
