Megaloblastic anaemia of infancy

Summary A clinical and haematological study of 210 infants with megaloblastic anaemia stresses its frequency among hospitalized children. The probable etiological factors of MAI seemed to be maternal malnutrition during pregnancy and lactation, prolonged breast feeding, inadequate breast milk intake, poor weaning diet and repeated chest/gastrointestinal infections. The occurrence of MAI even during the first six months of life in full term newborns on breast milk was seen though the most frequent age period was 9 to 12 months. The characteristic, clinical profile of MAI as well as the unusual modes of its presentation and physical findings have been stressed. Anaemia was macrocytic in 73.8%, normocytic in 16.2% and microcytic in 10.0%. Iron deficiency as judged from serum iron studies and marrow haemosiderin estimation was met with in 24.8% and 44.3% respectively. The therapeutic approach for the advanced and complicated cases has been presented and a few suggestions about its prevention made There was a mortality of 7.1% and 18.6% cases had an unsatisfactory response, implying that MAI is a serious diseae, and if advanced and complicated, offers a challenge to therapeutic skill.

Cardiolipin-fluorescent (M1) antimitochondrial antibody and cholestatic hepatitis in secondary syphilis

Summary A 27-year-old black male with secondary syphilis and cholestatic jaundice is presented. The liver biopsy was believed to be most consistent with large bile duct obstruction, but both the ultrasound and endoscopic retrograde cholangiography were normal. Prior to treatment with penicillin, his serum was positive for antimitochondrial antibody. After treatment, the antibody was no longer detectable and the jaundice gradually resolved. The patient's pretreatment serum was, after further analysis, found to be positive for the antibody to the M1 antimitochondrial antigen subtype, which is identical to cardiolipin, the antigen in both the VDRL and Wasserman tests. A review of hepatic involvement in secondary syphilis is presented.     

Cerebral infarction in association with Ecstasy abuse.

A previously fit 35 year old man presented with a right hemiparesis and dysphasia 36 hours after abuse of Ecstasy (3,4-methylenedioxymethamphetamine). Computerized axial tomography scan demonstrated an extensive acute left cerebral infarction and carotid digital subtraction angiogram, 2 days after admission, revealed left middle cerebral artery occlusion. There were no other known risk factors and all other investigations were negative. The patient made a partial recovery. We propose an association between Ecstasy abuse and cerebral infarction.     

Distribution of Plasmodium falciparum genotypes in clinically mild and severe malaria cases in Orissa, India

A cross-sectional study was conducted in a malaria hyperendemic state of India to ascertain the distribution of Plasmodium falciparum genotypes in patients with mild (n=40) and severe (n=35) malaria. PCR and nested PCR were used to determine the glutamate-rich protein (GLURP), merozoite surface proteins 1 and 2 (MSP1 and MSP2) and knob-associated histidine-rich protein (KAHRP) for characterization of the parasite. The results indicate that (i) the 200bp allele of the MAD20 family of MSP1 and the 550bp allele of the 3D7 family of MSP2 show over-representation in severe malaria cases; (ii) the multiplicity of infection with respect to MSP2 alleles is significantly higher (P<0.001) in severe cases than in mild cases; and (iii) comparison with the findings of other studies leads to the conclusion that the distribution of P. falciparum genotypes between different clinical groups differs geographically.     

Premorbid adjustment in first episode schizophrenia and schizoaffective disorders: a comparison of social and academic domains

OBJECTIVE: Recent evidence suggests that premorbid adjustment in schizophrenia and related disorders can be separated into social and academic domains. In this paper, we examine the correlates of and prognostic significance of social and academic premorbid adjustment in a sample of 113 patients. METHOD: Premorbid adjustment, symptoms and cognitive functioning were assessed at presentation for treatment and symptoms were re-assessed after a year of treatment. RESULTS: Females and those with a diagnosis of schizoaffective disorder were found to have better premorbid adjustment in the academic domain, but not in the social domain. Neurocognitive functioning was more consistently related to academic than social adjustment. Better social and academic premorbid adjustment was correlated with lower negative symptoms after 1 year of treatment, but neither was a significant predictor of positive symptoms. CONCLUSION: Social and academic premorbid adjustments show different relations to gender, specific diagnosis and neurocognitive functioning in schizophrenia and related disorders.     

Bridging to transplant with the HeartMate left ventricular assist device: The Columbia Presbyterian 12-year experience

OBJECTIVE: Implantation of a left ventricular assist device as a bridge to transplantation has become an acceptable approach for patients with end-stage heart failure. Our long-term results with 3 Thoratec HeartMate devices are presented to outline improvements in successful bridging to transplantation and post-transplant survival. METHODS: From August 1990 through January 2003, 243 patients underwent implantation of Thoratec HeartMate devices as a bridge to transplantation. This included 52 (21.4%) pneumatic devices, 17 (7.0%) dual-lead vented electric devices, and 174 (71.6%) single-lead vented electric devices. RESULTS: Mean age was 49.7 +/- 13.7 years. Mean support time was 78.1 +/- 82.9 days (0-541). Bridging success increased from 63.5% (n = 33) for pneumatic devices to 64.7% (n = 11) for dual-lead vented electric devices and 72.4% (n = 126) for single-lead vented electric devices (P =.005). Posttransplant 1-, 3-, and 5-year actuarial survival increased from 87.5%, 78.1%, and 71.9% in patients with pneumatic devices to 91.5%, 86.9%, and 81.3%, respectively, for patients with single-lead vented electric devices. Device infection and malfunction occurred in 17.7% (n = 43) and 12.8% (n = 31) of patients, respectively. CONCLUSIONS: Successful bridging to transplantation and posttransplant survival has improved over time. Left ventricular assist devices have become increasingly more effective in bridging patients with end-stage heart failure to transplantation. This is likely due to a combination of better patient selection, improvements in clinical practice, and evolution in device design.
