Cerebral zygomycosis

Fifty-six patients with cerebral zygomycosis (mucormycosis) were seen during the period 1971-2001 in two tertiary care hospitals located in south India with tropical climate and catering to neurological diseases. Forty-four patients had rhinocerebral and twelve patients had isolated central nervous system (CNS) zygomycosis. Of these, ten were culture proven (Rhizopus oryzae in eight and Mucor in two); 30 were diagnosed as probable and 16 were diagnosed possible; mixed infections were seen in three patients. Diabetes mellitus was the predisposing condition in a majority (31/44) of patients with the rhinocerebral form of zygomycosis. The tissue obtained at biopsy/autopsy in either form showed necrotic/infarcted tissue with neutrophilic infiltration with broad non-septate hyphae showing irregular branching. The outcome was poor despite surgical excision and antifungal therapy. The high concentration of spores in a mouldy environment, the bird population and improper disposal of hospital waste may facilitate healthy hosts presenting with primary CNS disease.     

Cervical cancer screening in Tamilnadu, India: a feasibility study of training the village health nurse

Uterine cervical cancer is the most common malignancy among females in developing countries, including India. The success of cervical cancer screening programs in North America and Western Europe has been the result of centralized cervical-cytology screening. This is not possible in the villages (n=17,000) of Tamilnadu where 58 percent of females in rural areas are illiterate, health infrastructure is mediocre, and cervical cytology is unknow. The present study was undertaken to examine if the village health nurse (VHN) could be trained quickly to identify a cervical abnormality by visual inspection so that we could down stage the cancer to earlier stages, more amenable to treatment. VHNs also would be trained to take an adequate Pap smear. A total of 101 VHNs were trained in batches and returned to their villages. Within two years, 6,459 engible women in the study area were screened. The agreement between the gynecologists and the VHNs in identifying cancer among those with abnormal cervix was 95 percent, and 80 percent of the Pap smears taken by VHNs were adequate by WHO criteria, making the feasibility study highly successful.Authors are with The Cancer Institute (WIA), Adyar, Madras, Tamil Nadu,India.

Nonsystemic vasculitic neuropathy

The clinical, electrophysiological and pathological features and prognosis of 9 patients with nonsystemic vasculitic neuropathy are described. Nonsystemic vasculitic neuropathy accounted for 3% of cases of biopsy proven cases of various neuropathies and formed 56% of vasculitic neuropathy. Both clinically and on electrophysiological testing, mononeuritis multiplex was the form of neuropathy in 5 patients and 3 had sensory neuropathy. All the patients had a necrotizing vasculitis on nerve biopsy. Axonal degeneration was seen in teased fibers in all the patients. Eight patients showed good functional recovery one was left with mild bilateral claw hands.     

Duodenojejunitis: is it idiopathic or is it Henoch-Schönlein purpura without the purpura?

BACKGROUND: Henoch-Sch?nlein purpura is a small-vessel vasculitic disease that most often affects the skin. Gastrointestinal manifestations have been well described, including duodenojejunal inflammation (DJI). METHODS: Four children with DJI and clinical features of HSP are described, in whom the rash was either not present or appeared atypically late in the illness. RESULTS: The characteristic rash did not develop in three children, and it developed much later in one. The patients (three boys and one girl) were aged between 7 and 9 years (mean, 7.5 years). Growth characteristics were normal. In all patients, pain occurred acutely with colicky abdominal pain in the spring or fall of the year, and all stools were positive for occult blood. No infectious cause was identified. Upper gastrointestinal endoscopic examinations demonstrated significant visual and histologic duodenitis in a pattern consistent with previous reports in children with known HSP. Factor XIII activity was absent. Immunoglobulin A levels were increased in three of four children. All children made a prompt recovery with the administration of intravenous glucocorticoids. In one child, the characteristic rash of HSP developed 18 weeks after the initial examination. CONCLUSION: Duodenojejunal inflammation may be the primary manifestation of HSP, even in the absence of the characteristic rash.     

Cerebral mycetoma with cranial osteomyelitis

Craniocerebral maduromycetoma is extremely rare. The authors describe a case of maduromycetoma involving the left parietal cortex, bone, and subcutaneous tissue in a young male farm laborer who presented with left parietal scalp swelling that had progressed into a relentlessly discharging sinus. Computed tomography (CT) scanning of his brain revealed osteomyelitis of the parietal bone with an underlying homogeneously enhancing tumor. Intraoperatively, the mass was revealed to be a black lesion involving the bone, dura mater, and underlying cerebral cortex. It was friable and separated from the surrounding brain by a thick gliotic scar. Gross-total excision was performed, and the patient was placed on a 6-week regimen of itraconazole. To the authors' knowledge, this is the first instance of cerebral mycetoma with CT findings reported in the literature.     

First detection of measles genotype D7 from India

National Institute of Virology, India has instituted molecular surveillance of measles strains in the country. In phased manner, three major cities Pune, Chennai and Bangalore were covered. Throat swab and urine from suspected measles cases from Chennai and Pune and freshly frozen brain tissues, CSF from suspected SSPE case from Bangalore were subjected to RNA extraction and Measles N&H gene RT-PCR as per WHO standard protocols. PCR positive products were sequenced. Sequence alignment and phylogenetic analysis was carried out using WHO standard reference sequences. Virus isolation was attempted using B95a cell line. Measles genotype D7 was detected from two classical measles cases (Chennai and Pune) and in a fulminant SSPE case (Bangalore). This is the first detection of measles genotype D7 from India.
