Simultaneous diagnosis of ulcerative jejunoileitis and coeliac disease in an elderly man

Ulcerative jejunoileitis (UJI) is a rare condition which usually develops in patients with established or simultaneously diagnosed coeliac disease (CD) and has been suggested to represent cryptic low-grade enteropathy-associated T-cell lymphoma (EATL). We report a case of a 78-year-old male patient with UJI and CD diagnosed at the same time. He presented with abdominal pain, diarrhoea and weight loss and had serological, endoscopical, radiological and histological findings compatible with the diagnoses of both UJI and CD. The possibility of EATL was carefully excluded. The patient exhibited significant symptomatic improvement with a gluten-free diet, probably indicating an early stage of disease despite his old age. In conclusion, this rather unusual case of an elderly patient presenting with UJI and CD without evidence of EATL supports the great heterogeneity of these diseases not only in their clinical presentation but even in their course and complications.     

NEONATAL OUTCOME IN MECONIUM STAINED DELIVERIES — A PROSPECTIVE STUDY

This prospective study analyzes the neonatal outcome in deliveries complicated by meconium stained amniotic fluid. In a study of 1000 live born deliveries, meconium staining of amniotic fluid was seen in 50 (5%) deliveries. Out of these, 20 newborns (40%) developed classical signs of meconium aspiration syndrome and were managed according to a predetermined protocol. Multiparity, term deliveries, use of sedatives in mother, intrauterine growth retardation and prolonged labour were some of the risk factors for development of meconium aspiration syndrome in newborns. This study highlights the need for review of management protocol in newborns after meconium staining of the amniotic fluid, including the use of prophylactic antibiotics.KEY WORDS: Amniotic fluid, Delivery, Meconium aspiration, Respiratory distress syndrome     

Metabolic syndrome is associated with severe fibrosis in chronic viral hepatitis and non-alcoholic steatohepatitis

Background The prevalence of metabolic syndrome and its possible impact on the severity of liver histological lesions have not been studied prospectively in chronic liver diseases. Aim To investigate the prevalence of metabolic syndrome in patients with chronic viral hepatitis or non‐alcoholic steatohepatitis, and to determine its associations with histological severity. Methods We prospectively included 317 patients (hepatitis B e antigen‐negative chronic hepatitis B: 95, chronic hepatitis C: 176, non‐alcoholic steatohepatitis: 46) with liver biopsy. Metabolic syndrome was defined using the Adult Treatment Panel III criteria. Histological lesions were evaluated according to Ishak’s or Brunt’s classification. Results Metabolic syndrome was present in 10.4% of patients being significantly more prevalent in non‐alcoholic steatohepatitis than in chronic viral hepatitis (41.3% vs. 5.1%, P < 0.001). In chronic viral hepatitis, cirrhosis (stages 5–6) was independently associated with increasing age, higher aspartate aminotransferase and gamma‐glutamyl‐transpeptidase levels, severe necroinflammation and metabolic syndrome (P = 0.016). In non‐alcoholic steatohepatitis, severe fibrosis (stages 3–4) was independently associated with severe necroinflammation and metabolic syndrome (P = 0.033). Presence of metabolic syndrome was not associated with presence or severity of steatosis both in chronic viral hepatitis and in non‐alcoholic steatohepatitis. Conclusion Metabolic syndrome is more prevalent in non‐alcoholic steatohepatitis than in chronic viral hepatitis; it is associated independently with more severe fibrosis but not with the severity of steatosis, both in chronic viral hepatitis and in non‐alcoholic steatohepatitis.

Cutaneous Crohn''s disease mimicking Melkersson–Rosenthal syndrome: treatment with methotrexate

A woman with a 5-year history of unilateral orofacial granulomatosis required repeated evaluations (including sequential colonoscopies) to establish the diagnosis of cutaneous Crohn's disease, a condition that proved responsive to low doses of oral methotrexate administered weekly. To our knowledge this is the first report describing the use of methotrexate for treatment of orofacial granulomatosis caused by underlying Crohn's disease.     

Correlation of acetylcholinesterase activity in the brain and blood of wistar rats acutely infected with Trypanosoma congolense

ObjectiveTo investigate the neurotransmitter enzyme Acetylcholinesterase (AChE) activity in the brain and blood of rats infected with Trypanosoma congolense (T. congo).MethodsPresence and degree of parasitemia was determined daily for each rat by the rapid matching method. AChE activity was determined by preparing a reaction mixture of brain homogenate and whole blood with 5, 5-dithiobisnitrobenzioc acid (DTNB or Ellman's reagent) and Acetylthiocholine (ATC). The increase in absorbance was recorded at 436 nm over 10 min at 2 min intervals. Trypanosome species identification (before inoculation and on day 10 post infection) was done by Polymerase chain reaction using specific primers.ResultsThe AChE activity in the brain and blood decreased significantly as compared with the uninfected control. The AChE activity dropped to 0.32 from 2.20 μmol ACTC min^?1mg protein^?1 in the brain and 4.57 to 0.76 μmol ACTC min-1mg protein^?1 in the blood. The animals treated with Diminaveto at 3.5 mg/kg/d were observed to have recovered significantly from parasitemia and were able to regain AChE activity in the blood but not in the brain as compared to the control groups. We also observed, that progressive parasitemia resulted to alterations in PCV, Hb, RBC, WBC, neurophils, total protein, lymphocytes, monocytes and eosinophil in acute infections of T. congo. Polymerase chain reaction (PCR) of infected blood before inoculation and on day 10 post infection revealed 600 bp on agarose gel electrophoresis.ConclusionsThis finding suggest that decrease in AChE activity increases acetylcholine concentration in the synaptic cleft resulting to neurological failures in impulse transfer in T. congo infection rats.
