ABSTRACT

Arteriovenous malformations of the lung are relatively uncommon lesions with varied clinical presentation. Nearly half of these are associated with Osler-Rendu-Weber disease. Magnetic resonance angiography is an accurate and non-invasive diagnostic modality. We report a case of a 56-year-old male who had massive haemothorax due to rupture of a pulmonary arteriovenous malformation arising from the right interlobar artery.

ABSTRACT

Primary lymphoma of the duodenum presenting with obstructive jaundice is a rare entity. We report a case of primary non-Hodgkin's lymphoma of the duodenum producing obstructive jaundice in a middle aged lady, where the concentric thickening of the duodenal wall also gave rise to symptomatic partial high small bowel obstruction in due course. Guided aspiration and flowcytometry established a diagnosis of diffuse large B-cell lymphoma.

ABSTRACT

Melnick-Needles syndrome or osteodysplasty, a monogenic heritable bone dysplasia, is characterized by a typical facies and characteristic radiological findings. Less than 70 well-documented cases have been reported in literature; most of them were sporadic. We report the first case from Eastern India in an adolescent male, who had cranio-vertebral junction anomalies and presented with spastic quadriparesis at the age of 13 years.

ABSTRACT

Hepatocyte mitochondrion functions as a cause and as a target of liver injury. Since the mitochondria are under dual control of nuclear DNA and mitochondrial DNA (mtDNA), mutations in genes of both classes have been associated with inherited mitochondrial hepatopathies. Point mutations, deletions, insertions, rearrangements, DNA depletion--all have been identified. Many factors influence the prevalence of mitochondrial disorders, including the mutations rate, inheritance pattern, population structure, and the genetic background. In primary disorders, mitochondrial defect is the primary cause of liver disease often producing fatal hepatic failure in infancy or childhood. In secondary disorders, insult to mitochondria is caused by either a gene defect that affects non-mitochondrial proteins or by an exogenous injury to mitochondria. Diagnosis should be suspected in cases of liver disease with neuromuscular symptoms, multisystem involvement that cannot be explained by a single pathology or rapidly progressive liver failure in early childhood. Laboratory findings in the blood and urine show an altered redox status. Various antioxidants, vitamins, cofactors, and electron acceptors have been for proposed but none is effective. Presence of neuromuscular or extraintestinal involvement in primary disorder precludes the use of liver transplantation.

ABSTRACT

Chorea, hemichorea, hemiballismus and other parkinsonian movement disorders have been described in type 1 diabetic patient with uncontrolled hyperglycemia. In comparison, abnormal movements in diabetic ketoacidosis are rare though ketosis due to other causes can cause parkinsonism-like movement disorders. We report two cases of diabetic ketoacidosis where hemifacial spasm was the predominant clinical manifestation for which no organic cause could be detected with relevant investigations. The symptoms subsided with conventional therapy for diabetic ketoacidosis and never recurred.

ABSTRACT

A 38 years female presented with three episodes of venous thrombosis over one year--first in left femoral vein, next in splenic vein causing haematemesis and malena and lastly in inferior vena cava causing Budd-Chiari syndrome. During third episode, endoscopic cholangiopancreatography and guided biopsy established a diagnosis of cholangiocarcinoma at the mid portion of common bile duct. The disease was far advanced with cervical lymph node metastasis.

ABSTRACT

Reverse transcription-PCR (RT-PCR) technique was adopted to amplify a 101 basepair nucleotide sequence of bluetongue virus (BTV) genome segment 6. The specificity of the amplicon was determined by its approximate size in 3% agarose gel electrophoresis, digestion with restriction enzyme MspI, dot-blot hybridization and cycle sequencing. The technique was found to be suitable for detection of bluetongue virus in infected cell culture and clinical samples.

ABSTRACT

This study was undertaken in rats to ascertain the role of zinc as an antiulcerogenic agent employing its more bioavailable gluconate derivative. Pretreatment with zinc gluconate 10 mg/kg body wt orally for three consecutive days, protected against alcohol induced gastric epithelial damage and also significantly prevented non-steroidal anti-inflammatory drugs (NSAID) induced gastric ulcer in rats. The enhanced levels of mucus, and hexosamine and decreased acid output in the gastric secretion of zinc treated rats, increased the gastric mucosal barrier. Studies on the mechanism of action suggested the involvement of -SH groups in producing gastric antisecretory effect. Thus, zinc gluconate at > > 100 microM concentrations inhibited H(+)-ion transport which could be reversed by incorporating beta-mercaptoethanol in the secretory solution (luminal side). On the other hand, beta-mercaptoethanol added from the nutrient side showed no effect on the inhibition of H(+)-transport indicting that the implication of -SH groups may not be the sole factor. Zinc appeared to play a vital and multifaceted protective role in chemically induced gastric ulcer disorders.
