Profile of non-compressive myelopathy in eastern India: a 2-year study.

Eighty-two patients with non-compressive myelopathy have been studied from July 1994 to June 1996 in Bangur Institute of Neurology and S.S.K.M. Hospital, Calcutta, of which 48 patients were men and 34 patients were women. Presentation was acute in 40 patients (48.78%), subacute in 7 (8.53%), chronic in 27 (32.92%) and history of relapse and remission in 8 (9.75%) patients. Preceding as well as simultaneous fever was observed in 16 cases (19.5%); vaccination (anti-rabies) in 1 case (1.21%); drug abuse in 1 case (1.21%); arthralgia-myalgia and rash in 2 cases (2.42%) and history of electrocution in 2 cases (2.42%). Only pyramidal tract involvement was present in 24 cases (29.26%) and remaining 58 cases (70.73%) had pyramidal tract affection with other sites of involvement. CSF study carried out in 60 cases, revealed rise of protein in 31 (37.8%); oligoclonal band had been detected in 6 (7.31%), pleocytosis in 18 cases (21.95%) and increased IgG index greater than 6.66 in 2 cases (2.42%). CT myelogram done in 23 cases revealed no abnormality. MRI study carried out in 59 cases showed myelomalacia in 1 (1.21%); demyelination plaque in 14 cases (17.07%); atrophy of cord in 3 (3.65%); infarction of cord in 1 (1.21%) and in 40 cases (48.78%) no abnormality could be detected. Etiological diagnosis could be established in 59 (71.95%) cases such as transverse myelitis or myelopathy (post infectious) in 24 (29.26%); demyelination in 16 (19.51%); vascular and vasculitis in 3 (3.65%); toxic in 1 (1.21%); physical (electrocution) in 2 cases (2.42%). In the remaining 23 cases (28.04%) no aetiological factors could be found.

Clinical profile of multiple sclerosis in Bengal.

Forty five patients of multiple sclerosis diagnosed on the basis of Poser's criteria from West Bengal were studied. The male-female ratio was 1:1.5, mean age of onset 31.83 years in male and 29.11 years in females. The maximum cases were between the 3rd and 4th decade. Definite MS comprised of 60%, while remaining 40% were probable. Visual impairment (53.33%), weakness of limbs (31.11%) and sensory paraesthesia (20%) were the common presenting symptoms whereas pyramidal tract involvement (93.33%) with absent abdominal reflexes (90%) and optic pallor (64.44%) were common signs. Posterior column and spinothalamic sensations were involved in 55% and 51% of cases respectively. Inter-nuclear ophthalmoplegia was present in 6.66% of cases. Pattern of involvement commonly showed three or more sites of lesion. Optico-spinal affection was present in 22.2% of cases. Relapsing and remitting course was found in 48. 91%, relapsing and progressive course in 33.33% and chronic progressive in 17.8%. MRI of brain showed positive results in 16 out of 23 cases. CSF study showed increased positivity in estimation of immunoglobulin level than oligoclonal band. Findings revalidate the disease pattern as being similar to that in other parts of India as well as Asia.

Pattern of motor neurone disease in eastern India.

A clinical study about the pattern of motor neurone disease in eastern India was carried out from July 1993 to June 1995 at Bangur Institute of Neurology, Calcutta and SSKM Hospital, Calcutta. A total of 110 cases were studied and they constituted 0.11% of all neurological cases seen in the general OPD. Of 110 cases, amyotropic lateral sclerosis (ALS) constituted 43.6%, progressive muscular atrophy (PMA) 10.9%, post-polio progressive muscular atrophy (PPMA) 1.8%, spinal muscular atrophy (SMA) 20%, atypical form Madras pattern of MND (MMND) 0.9% and monomelic amyotrophy (MMA) 22.7% of cases. Disease is more common in males than females and average duration of symptoms before presentation varied from 1 to 12 months. Most of the patients were either agricultural labourers or manual workers in ALS variety whereas MMA variety was evenly distributed in both hard labourers and sedentary workers. Most of the patients in MMA and SMA groups presented before 30 years of age whereas ALS and PMA group presented after 30 years. Trauma was the commonest antecedent event in ALS and MMA followed by electrocution in the same two groups. Family history was found to be absent in SMA group though the disease is considered as a hereditary one. Weakness of the limbs and wasting of the muscles were common presenting symptoms and signs. Bulbar symptoms and signs were found only in the ALS group. EMG showed neurogenic pattern and mixed pattern in most of the patients in all groups. Only a few patients showed myopathic pattern. Neuroimaging study helped in exclusion of compressive lesion excepting two cases of MMA where facetal hypertrophy was present. Monomelic amyotrophy, a special variety of motor neurone disease, is not rare in this part as compared to other parts of India and Asia.

Prognostic factors in intracerebral haemorrhage.

In a prospective study, the prognostic value of clinical characteristics and CT scan findings in 50 patients of intracerebral haemorrhage (ICH) has been examined. Follow up has been done over 6 months period. Each patient has been individually followed up for 8 weeks. At the end of the follow up period 34% of the patients died, 36% were dependent on outside help for daily living while 30% were capable of independent existence. Age of more than 60 yrs, Glasgow Coma Scale (GCS) Score of 6 or less (in a modified Scale of 10) at the time of admission, ICH volume greater than 30 ml., midline shift in CT scan of more than 3 mm and presence of intraventricular haemorrhage (IVH) and hydrocephalus had an adverse impact on outcome. Young age, GCS score of more than 8, ICH volume of less than 20 ml, presence of lobar haemorrhage and absence of IVH/hydrocephalus were associated with relatively favourable outcome.
