Intracerebral Haemorrhage: A Rare Presentation of Phaeochromocytoma.

Phaeochromocytoma is a rare childhood adrenal medullary catecholamine secreting tumour, arising from the chromaffin cells of the sympathetic origin derived from the neural crest cells. Only a few cases have been reported in the literature so far. We report an uncommon presentation in a 5-year-old boy with intracerebral haemorrhage, hemiplegia, and paroxysmal hypertension. Magnetic resonance imaging of the brain showed chronic and acute hemorrhagic infarcts in the left cerebral hemisphere and no vascular anomaly seen on cerebral venogram. Computed tomography scan abdomen showed a mass in the lesser sac and urinary catecholamines were elevated. The patient underwent exploratory laparotomy and the mass was excised in toto. Histopathological examination (HPE) confirmed the diagnosis. This case illustrates the need for keeping in mind atypical presentations of phaeochromocytoma especially in children; as it is a treatable cause of hypertension and early diagnosis with adequate management can prevent morbidity and fatal outcomes.

The chik sign in dengue.

The "chik sign" is considered to be one of the most common cutaneous features of chikungunya fever and has been considered unique to this disorder. It consists of brownish hyperpigmentation involving the nose. We report a case of a 3-year-old boy with dengue infection who presented with macular hyperpigmentation of nose simulating the chik sign. Hyperpigmentation is an unusual cutaneous manifestation in cases of dengue.

Amitraz: A Perpetual Silent Menace Among Children in Developing Countries-A Case Report.

Amitraz is an acaricide and insecticide used to treat ticks, which infest domestic animals in developing countries. Because of its widespread use, it is one of the common poisons unintentionally consumed by infants and children when left unsupervised. A 3-year-old boy was brought with unintentional consumption of Amitraz. On examination, he was found to be progressively drowsy, with an irregular pulse, bradycardia, and hypotension. He was treated with atropine, intravenous fluids, and dopamine infusion; hemodynamic stability was achieved within 36 hours after ingestion. Amitraz is an unusual but deadly poison unintentionally consumed by children. It can be suspected in the setting of rural households in developing countries having pets. There is no antidote available, and treatment is mainly supportive.

Recurrent and novel GLB1 mutations in India.

GM1 gangliosidosis is a lysosomal storage disorder caused by mutations in the GLB1 gene, leading to the deficiency of the enzyme ß-d-galactosidase. In this study, we report molecular findings in 50 Asian Indian families with GM1 gangliosidosis. We sequenced all the exons and flanking intronic sequences of GLB1 gene. We identified 33 different mutations (20 novel and 13 previously reported). The novel mutations include 12 missense (p.M1?, p.E129Q, p.G134R, p.L236P, p.G262E, p.L297F, p.Y331C, p.G414V, p.K493N, p.L514P, p.P597L, p.T600I), four splicing (c.246-2A>G, c.397-2A>G, c.552+1G>T, c.956-2A>G), three indels (p.R22Qfs*8, p.L24Cfs*47, p.I489Qfs*4) and one nonsense mutation (p.Q452*). Most common mutations identified in this study were c.75+2InsT (14%) and p.L337P (10%). Known mutations accounted for 67% of allele frequency in our cohort of patients, suggesting that these mutations in GLB1 are recurrent across different populations. Twenty three mutations were localized in the TIM barrel domain, ß-domain 1 and ß-domain 2. In silico sequence and structure analysis of GLB1 reveal that all the novel mutations affect the function and structure of the protein. We hereby report on the largest series of patients with GM1 gangliosidosis and the first from India.

A Case of Sanfillippo's Disease Correlating Clinical and Biochemical Findings.

The mucopolysaccharidoses (MPSs) are a heterogeneous group of rare inherited disorders caused by deficiency of lysosomal enzyme necessary to break down mucopolysaccharides or glycosaminoglycans (GAGs). We had combined clinical findings and ophthalmological features. Biochemical test for urine glycosaminoglycans was done for confirmation of diagnosis in the patient. The case of Sanfillippo's disease was characterized by delayed development, hyperactivity with aggressive behaviour. Coarse facial feature, hirsutism and sleep disorder. Urine GAG tests for MPS was positive in the case. Based on clinical findings and biochemical tests for MPS, this case was diagnosed as a type III mucopolysaccharidoses. Urinary GAG's electrophoresis is an important screening test for MPS suspected cases.

Primary Amoebic Meningoencephalitis in an Infant due to Naegleria fowleri.

Primary amoebic meningoencephalitis (PAM) caused by free-living amebae Naegleria fowleri is a rare and fatal condition. A fatal case of primary amoebic meningoencephalitis was diagnosed in a 5-month-old infant who presented with the history of decrease breast feeding, fever, vomiting, and abnormal body movements. Trophozoites of Naegleria fowleri were detected in the direct microscopic examination of CSF and infant was put on amphotericin B and ceftazidime. Patient condition deteriorated, and he was discharged against medical advice and subsequently expired. We also reviewed previously reported 8 Indian cases of primary amoebic meningoencephalitis (PAM) and observed that for the last 5 years, none of the patients responded to amphotericin B. Has an era of amphotericin B-resistant Naegleria fowleri been emerged? Management strategy of PAM needs to be reviewed further.

Fatal case of Naegleria fowleri meningo-encephalitis in an infant: case report.

Primary amoebic meningo-encephalitis (PAM) is extremely rare and is caused by Naegleria fowleri. It is ?commonly seen in older children who swim in water contaminated with Naegleria species. It is very rare to contract the illness by any other means. We report a case of PAM in an infant aged 6 months. To the best of our knowledge, only one other case of PAM in an infant has been reported from India. A high index of suspicion is required in infants who manifest similarly to pyogenic meningitis but whose CSF shows no bacterial organisms so that a wet mount of a CSF sample can be done for early detection of Naegleria fowleri infection and appropriate intervention.
