Anger and ego-defence mechanisms in non-psychiatric patients with irritable bowel syndrome.

BACKGROUND: Irritable bowel syndrome is commonly accepted as a disorder closely influenced by affective factors, which can either trigger the symptoms or contribute to their persistence, independently from their aetiology. It has been previously documented that irritable bowel syndrome patients respond to a variety of emotional states (anger, fear and anxiety) with an increase in colonic motility. AIMS: The aim of this study was to evaluate the experience and the expression of anger and the prevalent ego-defence mechanisms in a group of non-psychiatric patients with irritable bowel syndrome. SUBJECTS: Fifty-two patients with irritable bowel syndrome (18 males, 34 females) and 100 healthy volunteers from the community (44 males, 56 females) matched for age, level of education and social-status were enrolled. METHODS: Assessment was conducted using the State-Trait Anger Expression Inventory and the Defence Mechanism Inventory. RESULTS: No important differences between the two examined groups were found using the State-Trait Anger Expression Inventory and Defence Mechanism Inventory. CONCLUSIONS: It can be hypothesised that stable personality features and habits, such as anger disposition and defence mechanisms, play only a marginal role in irritable bowel syndrome, while psychological and psychosocial influences may act as predisposing or precipitating factors which contribute to the pathogenesis or expression of irritable bowel symptoms.

An endoscopic approach to the management of surgical bile duct injuries: nine years' experience.

BACKGROUND: The evaluation of the endoscopic treatment of surgical bile duct injuries, especially in the management of post-operative strictures, remains controversial. AIM: The aim of this study was to evaluate the feasibility of using endoscopic management from a study of the clinical reports of two of the main endoscopy units in Sicily. PATIENTS AND METHODS: A total of 137 consecutive patients were selected. There were 85 simple biliary fistulas: 64 from the cystic duct stump; 19 from the gall bladder bed; and two from intra-hepatic bile ducts. There were 52 biliary lesions: 15 complete transections; 12 incomplete lesions of the common bile duct with six associated strictures; five complete or incomplete sections of the right antero-medial duct; and 20 incomplete strictures (without leak). RESULTS: The success rate was 96.3% for simple biliary fistulas. Endoscopic therapy was feasible only in 40.6% of lesions of the common bile duct or the right antero-medial duct (13/32), but with 100% success. In the case of strictures (with or without associated leak), there was a good outcome in 88.2% of patients who completed the therapeutic procedure. CONCLUSIONS: Endoscopic management of simple biliary fistulas and incomplete lesions of the common bile duct is the preferred approach. If continued for 12-24 months, with the placement of three or more 10F stents, the management of stenoses is guaranteed to yield good results.

Endoscopic treatment of Barrett's epithelium with Argon Plasma Coagulation. Long-term follow-up.

BACKGROUND: Barrett's esophagus (BE) is a premalignant condition for the development of esophageal adenocarcinoma. Recently, many endoscopic therapies based on thermal or photobiologic ablation of BE have been provided, with positive short-term results in 60-100% of cases, but long-term results are still lacking. The aim of this study is to evaluate long-term results of BE endoscopic ablation with Argon-Plasma Coagulation (APC). METHODS: Thirty-five consecutive patients were treated (every 3 weeks) with APC until the eradication of BE and the squamous epithelium restoration were assessed. During the treatment and the first 6 months of follow-up, patients received 40 mg/die omeprazole; then the proton pump inhibitors (PPI) dose was 20 mg/die. Endoscopic and histologic controls have been performed every 6 months. The study considered the fìrst 32 patients who completed at least 24 months of follow-up, whose median was 49.5 months (range: 24-60). RESULTS: The ablation of BE was achieved with a median of 2.0 APC sessions, without side- effects. The recurrence of SIM (specialized intestinal metaplasia) was detected in 3 patients, while nor dysplasia or cancer developed. CONCLUSIONS: Our results confirm that APC can lead both to eradication of BE and the restoration of squamous epithelium. As recent reports indicated the persistence of SIM beneath the new epithelium and even a neoplastic growth (adenocarcinoma) in the treated area, despite APC, 2 questions have arisen: is APC unable to radically ablate BE or on the contrary are these findings due to defects of the ablative technique needing improvement? To settle more precise conclusions, further investigation with larger numbers of patients and for longer follow-up is required.

Effects of intravenous TRH on growth hormone and cortisol serum levels in children and adolescents with insulin dependent diabetes mellitus.

The effects of an iv thyrotropin releasing hormone (TRH) bolus on serum growth hormone (GH) and cortisol levels were evaluated in 59 children and adolescents with insulin dependent diabetes mellitus (IDDM) and in 24 healthy, age-matched control subjects. In the IDDM group GH baseline levels sharply rose within 30 min after TRH and successively normalized. On the contrary, TRH injection failed to affect GH serum concentrations in the control group. The GH increase after TRH in IDDM patients was positively correlated to age, but unrelated to other variables, such as sex, pubertal stage, duration of disease, glycemia, glycosylated hemoglobin, thyrotropin and T4 concentrations. Twenty-one out of 59 diabetics and only 1/24 controls exhibited a paradoxical GH response to TRH, arbitrarily defined as a precocious increase (within 30 min), of more than 100% with respect to the baseline value, associated with a GH peak greater than 10 ng/ml. Eighteen IDDM patients underwent a second TRH test 12 to 24 months later and substantially exhibited the same GH pattern documented the first time. The mechanism responsible for such anomalous GH responsiveness to TRH in IDDM is unclear. However, it cannot be attributed to a nonspecific stress reaction, as proven by the lack of a concomitant increase of cortisol serum levels in the same subjects.
