A case of unusual histiocytic colitis in a chronic alcoholic obese patient with ankylosing spondylitis.

A 64 year-old Caucasian man was first investigated 21 years ago for persistent diarrhoea. A colonoscopy revealed an erosive pancolitis with unusual vacuolated macrophages. Characteristics of ulcerative colitis or Crohn's disease were absent. Similar findings were observed consistently over the following years. A treatment with Sulfasalazine, Methotrexate or Budesonide was efficient. Histiocytic colitis is rare, and the various causes and different diagnoses are reviewed. The cause for the chronic pancolitis in this obese chronic alcoholic remains unknown at the time of writing. Links to the dyslipidaemia and chronic ankylosing spondylitis presented by the patient are possible hypotheses worth investigating further.

Cholestatic hepatitis after diagnostic ajmaline challenge.

We report a cholestatic hepatitis in an elderly woman after ajmaline challenge during electrophysiological testing for Brugada syndrome. No other medication was reported in the previous 6 months of the onset of jaundice. Liver biopsy showed a cholestatic hepatitis with mild biliary damage. Liver enzymes normalized within 2 weeks as well as jaundice. To the best of our knowledge this is the second case of histologically proved cholestatic hepatitis induced by intravenous ajmaline testing.

Multiple myeloma presenting as hepatic nodular lesion.

The diffuse infiltration by plasma cells in the liver is not uncommon in multiple myeloma (MM). However, a MM with hepatic mass is very unusual. We report a case of a 75-year-old male with hepatomegaly and a lesion occupying a voluminous space in the liver. A lambda light chain multiple myeloma was found in the check-up of this hepatic mass. We also provide a literature review.

Transjugular liver biopsy. An experience based on 500 procedures.

We report our experience based on 500 transjugular liver biopsies, a safe procedure even in high risk patients. Transjugular liver biopsies represents one third of all liver biopsies performed in our Hepato-Gastroenterology units. Liver specimen was adequate to evaluate liver architecture in 87.6% of patients in whom a minimal size of 7.6 mm of the liver core was found suitable for this purpose. The size of the liver specimen negatively correlated with the increase in hepatic venous pressure gradient (p < 0.0001). The liver biopsy was unsuccessful in 3.6% of patients. Hepatic capsular perforation occurred in 3.4% of patients but remained invariably asymptomatic.

[Hemobilia disclosing very small hepatocellular carcinoma ruptured into the biliary ducts]. / Hémobilie révélatrice d'un très petit carcinome hépatocellulaire rompu dans les voies biliaires.

In hepatocellular carcinoma, invasion of the biliary tree usually occurs in large tumors. We report a case of a minute hepatocellular carcinoma which invaded the biliary tree and was revealed by secondary hemobilia, in a 65-old alcoholic patient with cirrhosis. The tumour was not identified by preoperative morphological examinations. Surgical exploration was performed due to unexplained hemobilia. Tumoral debris were observed in the right intrahepatic biliary tract during operative choledoscopy, justifying a right hepatectomy. A 5 mm diameter tumour was found in liver specimen. No recurrence had occurred after 22 months. In conclusion, in cirrhotic patients, unexplained hemobilia can reveal a small, potentially curable, hepatocellular carcinoma which has spread to the biliary tree.

Liver injury related to amoxycillin-clavulanic acid: interlobular bile-duct lesions and extrahepatic manifestations.

We report eight cases of liver injury related to amoxycillin-clavulanate. Liver biopsy performed in seven patients revealed varying degrees of injury to interlobular bile ducts in all cases. Lesions included irregularity of the nuclei, vacuolization of the cytoplasm, lymphocytic infiltration, destruction and endothelialization of the bile duct epithelium. Ductopenia was not observed. In two patients liver injury was accompanied by prominent extrahepatic manifestations (acute interstitial nephritis in one and acute lacrimal gland inflammation and sialadenitis with prolonged xerostomia in the other). We conclude that interlobular bile-duct lesions of varying severity are a common feature in liver injury related to amoxycillin-clavulanate. Side effects of the drug include acute interstitial nephritis and sialadenitis.

Omeprazole in the treatment of patients with severe reflux oesophagitis not responding to H2-receptor antagonists and ineligible for surgery.

In 42 patients (25 men, 17 women, mean age 62 years) with severe erosive or ulcerative oesophagitis not responding to H2-receptor antagonist treatment over at least 3 months and ineligible for surgery, omeprazole was administered at an initial dose of 40 mg/day, subsequently reduced to 20 mg after healing of the lesions. Patients had monthly clinical, endoscopic, histological and laboratory assessment over the healing period, then were reevaluated 3-monthly over one year, then 6-monthly, during the maintenance treatment. Stages of oesophagitis were based on the Savary-Miller classification, modified for stage I (erosions must be present). With 40 mg omeprazole, healing was observed in 71%, 83% and 90% of the patients after 1, 2 and 3 months of treatment, respectively. After one month of treatment, a complete healing was less frequently observed in patients with stage IV oesophagitis pre-trial (55%) than in the patients with stages I, II and III pre-trial (90%) (p less than 0.05). Ninety per cent of the patients healed at one month were asymptomatic whereas 50% of the patients with incomplete healing still had symptoms, most often dysphagia, rarely heartburn. Maintenance treatment with 20 mg was sufficient in most patients, with a probability of remaining healed of 69% from 9 to 24 months after starting this dosage. In 9 patients with Barrett's oesophagus, the lengths of the circumferential metaplasia were found to be reduced after one year of treatment compared to pre-trial lengths (p less than 0.005). There was no further significant reduction of length after 2 years of treatment. Fasting gastrin was increased in most of the patients, although great inter-patient variability was observed; 50% of the patients had levels not exceeding 5 times the upper limit of normal. There was no consistent increase of enterochromaffin-like cell density in 29 patients investigated up to nearly 2 years of omeprazole administration. The treatment was well tolerated. By inducing a profound and sustained inhibition of acid secretion, as confirmed by pH monitoring, omeprazole promotes healing of the lesions of severe oesophagitis and prevents recurrence of lesions and symptoms. Omeprazole is therefore a valuable treatment for patients ineligible for surgery, particularly in the elderly.

[Treatment of familial rectocolonic polyposis with total colectomy using ileorectal anastomosis in 6 members of a family: the value of early diagnosis]. / Traitement de la polypose rectocolique familiale par colectomie totale avec anastomose iléo-rectale chez six membres d'une fratrie: intérêt d'un diagnostic précoce.

We report on the observation of six cases in a family of eight, all under 30, in whom the diagnosis was obtained at first hand by rectosigmoidoscopy. This procedure appears sufficient as the number of polyps tends to decrease with increasing distance from the anal margin. The recent finding of abnormalities of chromosome 5 (long arm) permits the identification of carriers of this genotype by simple blood examination (DNA probe), thus greatly enhancing the possibilities of screening for the disease. Each of our cases was managed with subtotal colectomy and ileorectal anastomosis. Preservation of the rectum was preferred to other techniques as all subjects were young, mildly affected and with good motivation for twice-yearly endoscopic follow-up. The surgical technique appears simple and quite safe with satisfactory functional results and easy feasibility of endoscopic surveillance.
