RESUMEN

This case is reported with the intention of highlighting the presentation of primary amebic meningoencephalitis as acute meningitis, a rare differential diagnosis with presence of free living amoebas in the CSF.

RESUMEN

Analysis of the management of 7 cases of extradural arachnoid cyst is presented. A brief review of the literature on the subject is presented. Seven cases of extradural arachnoid cysts were treated surgically between the years 1996 to 2002. These patients were analysed retrospectively. The average follow-up period was 32 months. Three patients were males and four were females and their ages ranged from 12 to 35 years. The patients presented with predominant complaint of progressive motor deficits. There were two cysts in the dorsal region, four in the dorsolumbar region and one in the cervicodorsal region. The extradural arachnoid cyst was located posterior to the dural tube and in the midline in six cases and all these cysts had bilateral multiple intervertebral foraminal extensions. In the case with a cervicodorsal cyst, the cyst was anterolateral to the dural tube and there was no foraminal extension. The surgery comprised of wide exposure of the cyst and radical marsupialization or resection of the cyst wall. There was no recurrence of the cyst during the period of follow-up. Radical resection of the walls leads to a lasting cure from extradural arachnoid cyst. The site of communication of the cyst contents with subarachnoid CSF could not be identified during the surgery in the series.

RESUMEN

Infrarenal aortic coarctation is a very uncommon vascular disease. It has been named as hypoplasia of abdominal aorta, mid aortic dysplasia, mid aortic syndrome, atrophy of aorta, atresia of the terminal aorta & atypical coarctation. The pathogenesis is still controversial. Hypertension is an almost universal feature of this disorder. We present a case report with postmortem findings of a young female patient having hypoplasia of abdominal aorta for its rarity.

RESUMEN

Oxidative stress plays an important role in the development of malarial anemia. The present study was undertaken to study the role of oxidant and antioxidants in the patients ofPlasmodium falciparum malaria (n=25),Plasmodium vivax malaria (n=25) as against the normal control subjects (n=25). The parameters included are the hematological [hemoglobin, erythrocyte adenosine deaminase (ADA) activity, ADP-induced platelet aggregation] and serum total lipid peroxide as an index of oxidative stress and antioxidants [erythrocytic superoxide dismutase (SOD) activity, serum vitamin E] & serum iron.Significant alterations in all above parameters were noted in both groups of malaria patients as compared to control subjects. Maximum significant alterations in hematological parameters were noticed inP. falciparum infection as compared toP. vivax malaria (p<0.001). Substantial rise in serum total lipid peroxides and a significant reduction in antioxidants such as serum vitamin E and serum iron were noted inP. falciparum malaria as compared toP. vivax malaria (p<0.001), whereas maximum decline in erythrocytic SOD activity was observed inP. vivax infection as compared toP. falciparum malaria (p<0.05). Follow-up examination revealed the restoration of the levels of all biochemical parameters to the normal level after 20 days of antimalarial therapy.The study specified severity ofP. falciparum malaria and also functional duality of oxidant.

RESUMEN

OBJECTIVE: To evaluate magnesium deficiency during and after acute myocardial infarction (AMI) and the role of intravenous magnesium therapy given in the early postinfarction period. METHODS: One hundred patients with AMI were randomly assigned to 2 equal groups and monitored over a 4-week period. The placebo group received intravenous dextrose solution and the trial group was given 15 g intravenous magnesium (62 mmol) over a 48-hour period. Serum magnesium levels were measured on days 1, 2, 4, and 6 after admission by calorimetry with methyl thymol blue. RESULTS: The groups were comparable in prevalence of risk factors for coronary artery disease and other acute parameters of AMI. The serum magnesium levels of a group of 50 controls were higher (1.61 +/- 0. 21 vs 1.23 +/- 0.27mEq/L) than in patients with AMI (P <.001). There was an increase in serum magnesium levels in the trial group on day 2 (1.73 +/- 0.27 vs 1.29 +/- 0.28 mEq/L; P <.001) as well as on day 4 (1.62 +/- 0.25 vs 1.38 +/- 0.36 mEq/L; P <.001). The trial group also showed significantly lower incidence of arrhythmias (8% vs 34%) and death (4% vs 20%). The mortality rate from pump failure was reduced in the trial group (4% vs 14%). CONCLUSIONS: The serum magnesium levels in patients with AMI were lower compared with controls. The administration of intravenous magnesium to patients in the immediate postinfarction period is cardioprotective and decreases the incidence of arrhythmia, pump dysfunction, and death. Thus intravenous magnesium is a safe, effective, and inexpensive modality of treatment in AMI.

RESUMEN

Thirteen patients from 11 families were diagnosed as cases of haemophilia A or B during 1977 to 1984. The majority presented with post circumcisional bleeding. Cryoprecipitate and packed red cells were used in the management. Haemophilia and other inherited bleeding disorders are not as rare as otherwise assumed. This is the first report from Northern Nigeria.
