Kumar Atul,Kedar Sachin,Singh Rajinder
Indian Journal of Ophthalmology , 2002,
Abstract: We report two cases clinically diagnosed as idiopathic uveal effusion syndrome, where indocyanine green angiogram suggest non-specific choroidal inflammation as the underlying cause. Treatment with non-steroidal anti-inflammatory drugs was beneficial.
Visual fields in neuro-ophthalmology
Kedar Sachin,Ghate Deepta,Corbett James
Indian Journal of Ophthalmology , 2011,
Abstract: Visual field assessment is important in the evaluation of lesions involving the visual pathways and should be performed at baseline and periodically in the follow-up. Standard automated perimetry has been shown to be adequate in neuro-ophthalmic practise and is now the technique of choice for a majority of practitioners. Goldman kinetic visual fields are useful for patients with severe visual and neurologic deficits and patients with peripheral visual field defects. Visual fields are useful in monitoring progression or recurrence of disease and guide treatment for conditions such as idiopathic intracranial hypertension (IIH), optic neuropathy from multiple sclerosis, pituitary adenomas, and other sellar lesions. They are used as screening tools for toxic optic neuropathy from medications such as ethambutol and vigabatrin. Visual field defects can adversely affect activities of daily living such as personal hygiene, reading, and driving and should be taken into consideration when planning rehabilitation strategies. Visual field testing must be performed in all patients with lesions of the visual pathway.

Evaluation of subjective and objective cyclodeviation following oblique muscle weakening procedures
Sharma Pradeep,Thanikachalam S,Kedar Sachin,Bhola Rahul
Indian Journal of Ophthalmology , 2008,
Abstract: Purpose: To evaluate the subjective and objective cyclodeviational changes following different weakening procedures on superior and inferior oblique muscles Design: Comparative case series Materials and Methods: In a prospective institution based study, 16 cases of A pattern horizontal strabismus having superior oblique overaction were randomized to superior oblique weakening procedures: either silicon expander or translational-recession. Similarly, 20 cases of V pattern horizontal strabismus with inferior oblique overaction were randomized for inferior oblique weakening procedures: either 10 mm Fink′s recession or modified Elliot and Nankin′s anteropositioning. Cyclodeviation was assessed subjectively with the synoptophore and objectively using the fundus photograph before surgery and 3 months postoperatively. Change in cyclodeviation was measured by subjective and objective methods. The index of surgical effect (ISE) was defined as the net torsional change postoperatively. Results: The difference between the extorsional change induced by the two superior oblique procedures, silicone expander (-6°) and translational recession (-11.3°), was statistically significant (P=0.001). Translational recession caused more extorsional change (ISE=296%) than silicone expander surgery (ISE=107%). The two inferior oblique weakening procedures, Fink′s recession (+2.5°) and modified Elliot and Nankin′s anteropositioning (+4.7°) produced equitable amount of intorsional shift with no statistical difference (P=0.93). Objective measurements were significantly more than the subjective measurements. Conclusions: Different weakening procedures on oblique muscles produce different changes in cyclodeviation, which persists even up to 3 months. Subjective cyclodeviation is less than the objective measurements indicating partial compensation by sensorial adaptations.
Study of Crystallization Process in Se80In10Pb10 by Iso-Conversional Methods  [PDF]
Indra Sen Ram, Kedar Singh
Journal of Crystallization Process and Technology (JCPT) , 2013, DOI: 10.4236/jcpt.2013.32007

The crystallization kinetics of Se80In10Pb10 chalcogenide glass is studied using differential scanning calorimeter (DSC) at different heating rates (5, 10, 15 and 20 K/min) under non-isothermal conditions. Four iso-conversional methods (Kissinger-Akahira-Sunose, Flynn-Wall-Ozawa, Tang and Straink) were used to determine various kinetic parameters: crystallization temperature (Tα), activation energy of crystallization (Eα), Avrami exponent (nα) in non-isothermal mode. The transformation from amorphous to crystalline phase in Se80In10Pb10 is considered as a single step reaction mechanism.

Research Journal of Poultry Sciences , 2012, DOI: 10.3923/rjpscience.2012.1.3
Abstract: The incidence of death of broiler birds above 40 days suddenly increased in the month of July-October 2009 in Kathmandu valley. Birds that were presented for post-mortem examination at the Central Veterinary Laboratory, Tripureswor, Kathmandu were usually found dead on their backs with wings out-stretched. Gross abnormalities recorded on post mortem examinations were: muscle oedema, pulmonary, renal and liver congestion, dark black to pale yellow streaked liver bile filled gall bladder and congestive splenomegaly, blood clot in atrium haemorrhage in duodenal muscle, whitish yellow pasty fluid in proventriculus gland, greenish coloration marked intact feed particles in gizzard and excessive mucous filled swollen intestine. Incidence rate was recorded between 1.5-2.5% of the flock. The mean mortality rate due to sudden death syndrome was 1.3-9.6%. Penicillium sp. and Aspergillus sp. with CFU ranging from 56x10-4 to 62x105, to uncountable mold count, E. coli, Streptococcus sp. and Staphylococcus sp. were the usual organisms isolated from culture samples of liver, lung, spleen and proventriculus.
Clinical Epidemiological Investigation of Moldy Grain and Fodder Poisoning in Goat in Kathmandu Valley

Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2012.789.790
Abstract: An outbreak of a syndrome of unknown etiology associated with the feeding of moldy maize grain and green fodder to goat in a herd of male 3853 goats for sale for the Dashahara festival during the month of October 2010 in Kathmandu valley. In a period of 10 days 500 goats suddenly became ill with symptoms of anorexia, apathy, diarrhea and ruminal stasis. On clinical examination these goats were provisionally diagnosed with sudden illness and moldy corn/fodder poisoning was suspected. They were treated with biolive, tetrachlor, polyte, C-lyte, stress care and antidegnala liquor but 250 goats died. Necrosis of the fore stomach mucosa was the most characteristic gross pathological change. Clinical pathological findings included mild focal erosions to severe, diffuse, coagulative necrosis of the mucosa in the rumen, reticulum, omasum, congestion and hemorrhages in the abomasum. Liver with shrunken appearance and pale to yellowish discoloration with bile filled distended bladder, pin point hemorrhage in kidney, intestine with excessive mucus. On mycological and microbiological examination of tissue samples from post-mortem of dead goat on respective medium revealed the growth of fungal pathogens like Penicillium sp. with Staphylococcus. These results provide circumstantial evidence that feeding on moldy maize grain and green fodder leaves infested with Penicillium may cause outbreaks of systemic mycosis in goats.
A Laboratory Epidemiological Outbreak Investigation of Kumri(Cerebrospinal nematodiasis)and use of diethylecarbamazin in treatment of Goat in Banke district of Mid-Western Region of Nepal

Veterinary World , 2008,
Abstract: Seasonal occurrence (mainly in October-November) of a disease syndrome locally called ‘Kumri’ meaning weak back was observed in goats in Banke and other districts of western Terai in the last few years. Traumatic injury to the lumbar region, nutritional deficiencies and parasitism in the spinal cord were the likely causes considered. Based on the epidemiological pattern viz; seasonal occurrence, clinical symptoms, afebrile condition and local nature of infection, and non response to supplementation of vitamins and minerals, the disease was provisionally diagnosed as cerebrospinal nematodiasis. This has been further substantiated through laboraotry of Seteria spp in cattle in this region, detection of microfilaria in affected goat and treatment response of affected goats with diethylcarbamazine. As adult seteria spp in cattle, Buffalo and microfileria from blood smears of affected goat confirmed the cerebrospinal nematodisease in goat in Nepal. [Veterinary World 2008; 1(6.000): 168-170]

Can We Prevent Parkinson's and Alzheimer's Disease?
Kedar N
Journal of Postgraduate Medicine , 2003,
Abstract: Parkinson's disease (PD) and Alzheimer's (AD) are major progressive neurological disorders, the risk of which increases with advancing age (65 years and over). In familial cases, however, early onset of disease (about 35 years) is observed. In spite of extensive basic and clinical research on PD and AD, no preventive or long-term effective treatment strategies are available. Several studies have indicated that oxidative stress is a major risk factor for the initiation and progression of sporadic PD and AD. Even a-synuclein and b-amyloid fragments that are associated with the PD and AD, respectively, mediate part of their action via oxidative stress. Therefore, reducing oxidative stress appears to be a rational choice for the prevention and reduction in the rate of progression of these neurological disorders. This review provides a brief description of the epidemiology and pathogenesis of PD and AD, and the scientific rationale for the use of multiple antioxidants in the prevention of these neurological diseases.
