Mycobacterium avium intracellularae complex associated extrapulmonary axillary lymphadenitis in a HIV-seropositive infant--a rare case report.

Opportunistic infections by Mycobacterium avium intracellulare complex in HIV infected patients, though common in adults, are rarely seen in infants. We herewith report an interesting case of an eight month old infant presenting with isolated axillary lymphadenitis, later on diagnosed to be tubercular lymphadenitis by Mycobacterium avium intracellulare and finally proved to be seropositive for HIV infection born to previously undetected HIV seropositive parents.

Long term outcome in patients with severe head injury and bilateral fixed dilated pupils.

Patients with severe head injury with bilateral dilated unreactive pupils are considered to have a grave prognosis. Hence proper planning and aggressive management becomes mandatory for achieving good results. We present the outcome of consecutive 166 patients with severe head injury, admitted between January 1996 and December 2000 and analysed retrospectively. All the patients had an initial GCS of 8 or less and post resuscitation bilateral dilated unreactive pupils. Our aim was to analyze the long term outcome in these patients and identify the other significant prognostic factors. Of the 166 patients, 42 (25.30%) had a functional outcome (good recovery in 10.24%, moderate disability in 15.06%), and 124 (74.69%) had a poor outcome (death in 58.43% and severe disability in 16.26% of cases). There were 45 patients with polytrauma and 24 of these patients (53.33%) succumbed to the injuries. Obliteration of the basal cisterns and contusion were the common CT scan findings. Factors adversely affecting the survival included age of the patient, polytrauma with shock, initial GCS of 3 or 4, and compression of the basal cisterns on the initial CT scans. At follow up, most of the patients with a functional outcome showed a significant improvement in their motor function but continued to have neuro-behavioral and cognitive deficits.

Spinal cord and cauda equina compression in 'DISH'.

Diffuse idiopathic skeletal hyperostosis (DISH) has long been regarded as a benign asymptomatic clinical entity with an innocuous clinical course. Precise information is lacking in the world literature. Authors report the results of a retrospective analysis of 74 cases of DISH. Eleven patients presented with progressive spinal cord or cauda equina compression. In nine cases ossified posterior longitudinal ligament (OPLL) and in two cases ossified ligamentum flavum (OLF) were primarily responsible. Surgically treated patients (eight) had far better outcome as compared to the patients managed conservatively, as they had refused surgery. 'DISH' is neither a benign condition, nor it always runs a innocuous clinical course. In fact, in about 15% of the cases, serious neurological manifestations occur, which may require a major neurosurgical intervention.

Solitary skull metastasis from mucoepidermoid mimicking a parotid tumour.

Metastatic parotid tumours in the skull are very rare. An interesting case of a mucoepidermoid parotid tumour metastasizing to the skull vault is described in a patient who had previously been operated for a pituitary adenoma 20 years back with no post operative radiotherapy; however, she required hormonal supplementation therapy. She underwent an operation for a parotid tumour 7 years ago and received postoperative radiotherapy for the parotid tumour away from the site of the skull metastases. No local recurrence of the parotid tumour was noted. The initial diagnosis was that of a solitary intradiploic meningioma. Interesting clinico-radiological findings are presented.

Nutritional status of preschool children in the drought affected Kalahandi district of Orissa.

A community-based cross-sectional study was undertaken to determine the magnitude of undernutrition and protein-energy malnutrition among young children during 1996-97 in drought affected Kalahandi district of Orissa. A total of 751 children aged 0-5 yr were studied for anthropometry and clinical signs of nutritional deficiencies from 15 Gram Panchayats selected using probability proportionate to size sampling. There was no significant difference between boys and girls for nutritional status. According to weight-for-age, 57.1 per cent of the children were suffering from underweight (< median -2SD) and 21.3 per cent of children had very low body weights which were < -3SD of standard. Height-for-age and weight-for-height data showed that 41.8 per cent of children suffered from stunting and 27.9 per cent recorded wasting. The children below one year of age had relatively lower prevalence of malnutrition than the other age groups. The prevalence of clinical PEM in the form of marasmus was found in 0.7 per cent of children, while kwashiorkor was absent. This study showed that malnutrition is still a leading problem among preschool children of Kalahandi district and this has not improved in spite of nutrition intervention programmes which are currently in operation.

Symptomatic calcified subdural hematomas.

Two unique cases of chronic calcified subdural hematomas are reported in children as a long-term complication of a ventriculoperitoneal shunt. Both the patients had undergone shunt procedures in infancy for congenital hydrocephalus. In one patient, the cause of the hydrocephalus was aqueduct stenosis, while in the second patient, a lumbar meningomyelocele was associated with hydrocephalus. In both these patients, a ventriculoperitoneal shunt was done in infancy. In one of them, following the shunt surgery, a bilateral subdural collection was noticed which required burr hole evacuation. Both the patients remained asymptomatic for 9 years, when they presented to our center with acute raised intracranial pressure and contralateral hemiparesis. Both the patients had a relatively short history and had altered sensorium at admission. Surprisingly, in both the patients, the CT scan showed significant mass effect producing calcified subdural hematomas. The shunt systems were found to be working well at surgery. Craniotomy and excision of the calcified subdural hematomas was undertaken. Postoperatively, the patients showed satisfactory recovery, and at discharge the patients were doing well. At the follow-up at the outpatient clinic, the patients were asymptomatic.

Synthetic CD4 exocyclic peptides antagonize CD4 holoreceptor binding and T cell activation.

We have developed peptide analogs to analyze precise human CD4 substructures involved in MHC class II binding. Forms of the complementarity determining-like regions (CDRs) of the D1 domain of human CD4 were reproduced as synthetic aromatically modified exocyclic (AME) analogs and tested for their ability to block CD4-MHC II interactions and T cell activation. The exocyclic derived from CDR3 (residues 82-89) of human CD4, which specifically associated with CD4 on the T cell surface to create a heteromeric CD4 complex, blocked IL-2 production and antagonized the normal function of the CD4 receptor. The approach of creating novel synthetic antagonistic receptor complexes may represent a new receptor specific pharmaceutical approach to modulate biological function.

Maternal deaths--a ten-year study.

In a 10-year retrospective study of maternal deaths at RG Kar Medical College, Calcutta there were 651 maternal deaths with 410 in first 5-year period and 241 in second 5-year period. The leading causes of deaths were due to abortion, toxaemia, haemorrhage (antepartum and postpartum) and jaundice in pregnancy. Direct causes were responsible for death in 77.6% cases, indirect causes in 17.5% cases and unrelated causes in 4.9% cases. Majority (557) were unbooked and mostly multigravida (434) cases. Most of them (251) were in the age group of 20-25 years. Haemorrhage was the single most common cause to claim 188 lives. It was also noted that 155 deaths occurred within 12 hours of hospital admission.

Optic nerve injury in children. A prospective study of 35 patients.

Thirty-five children under 15 years of age with optic nerve injury are prospectively studies for their clinical presentation, radiological findings, visual evoked potentials and outcome. Over 50% were under 10 years of age. In half of the children, injury was due to fall from a height. Fracture of the skull was recorded in a third of the patients, and optic canal fracture was seen only in three children. Visual Evoked Potentials (VEP) were record in 30 children and were repeated several times in first three weeks. All the patients received corticosteroids and optic canal decompression was not carried out routinely. Overall spontaneous visual recovery was observed in 12 patients. Among the 30 children in whom Veps were recorded, 17 children had repeatedly absent VEP, and none of the children showed wave formation, 10 (77%) had visual recovery. Only in 5 patients an optic canal decompression was carried out several weeks after injury. This study brings out the role of VEP in children with optic nerve injury.
