Metaphyseal growth arrest lines in psychosocial short stature

Metaphyseal growth arrest lines are seen in children who experience significant physical stress such as infection or malnutrition over a sufficient period of time. These lines have not been reported previously in children with psychosocial short stature (PSS). Two boys and a girl with PSS with metaphyseal growth arrest lines on skeletal radiographs at the time of maximal stress in their homes are described. All three had reversible growth hormone insufficiency during admission, which is pathognomic for PSS. Multiple growth arrest lines in the distal end of the radius or vertebrae should alert clinicians to an alternative diagnosis in a child with growth hormone insufficiency. This may provide a clue to the diagnosis of occult PSS.     

Is the link between alcohol and cardiovascular death among young Russian men attributable to misclassification of acute alcohol intoxication? Evidence from the city of Izhevsk

BACKGROUND: Research on the aetiology of sudden cardiac death among young men in Russia strongly suggests an association with binge drinking. However, the possibility remains that such deaths are misclassified as being attributable to cardiovascular disease when they are really caused by acute alcohol poisoning. OBJECTIVE: To describe postmortem levels of blood alcohol in Russian men dying from various causes and so determine whether deaths from alcohol poisoning are being misclassified as cardiovascular deaths. SETTING: Ishevsk, capital of the Udmurt Republic, situated in the Ural region of the Russian Federation. METHODS: The study was part of a larger one on adult mortality. The study sample was 309 deaths among men aged 20-55 dying between August 1998 and March 1999 from other than neoplasms, infectious diseases or unspecified causes and on whom necropsy records could be obtained. Information on cause of death was extracted from death certificates and data on postmortem blood alcohol concentration (BAC) from forensic records. Blood alcohol concentrations were adjusted where necessary to allow for delay in necropsy. RESULTS: Medium or greater levels of intoxication occurred in a quarter of those recorded as dying from cardiovascular disease but in over half of those dying from external causes. BAC levels consistent with at least strong intoxication were seen in 13.5% of deaths from cardiovascular disease and 27.1% from external causes. No cardiovascular deaths had BAC at levels usually thought to be fatal while this level was seen in 26% of deaths from accidental poisoning. CONCLUSION: Evidence of recent consumption of alcohol is common among Russian men dying under the age of 55, with severe intoxication common where death is from external causes. However, the high death rates from cardiovascular disease in Russia cannot be explained by misclassification of deaths attributable to acute alcohol poisoning. This study thus resolves one of the outstanding controversies in the story of alcohol and cardiovascular disease in the former Soviet Union.     

Reversible “Pulvinar sign” in Wernicke's encephalopathy

Young onset dementia is a challenge. We describe a case, where a patient presented with psychosis, dementia and MRI showing pulvinar sign, all of this typical of variant Cruetzfelt Jacob disease (CJD). Subsequent investigations lead to the diagnosis of a treatable illness and patient was improved and MRI sign reversed, underlining again the importance of search needed for treatable diseases in any “typical” case of fatal illness.     

Antidiabetic and antioxidant potentials of spent turmeric oleoresin,a by-product from curcumin production industry

ObjectiveTo investigate the antidiabetic and antioxidant activity of spent turmeric oleoresin (STO).MethodsAntidiabetic activity of STO evaluated by α-amylase and α-glucosidase enzyme inhibition assays. The antioxidant capacity studied by DPPH., ABTS., superoxide radical scavenging and metal chelating activity methods.ResultsThe STO showed good antidiabetic activity by inhibiting key enzymes linked to type 2 diabetes, viz α-glucosidase and α-amylase with an IC50values of 0.71 and 0.16μg/mL respectively. The IC₅₀values for DPPH. and ABTS. assay were 58.1 and 33 μg/mL respectively. STO effectively scavenged the superoxide free radical with an IC50 value of 61.5μg/mL and showed a moderate iron chelation property.ConclusionsThe above study reveals that the spent turmeric oleoresin being wasted at present can be used as antioxidant and antidiabetic agent in food and neutraceutical products.
