Idiopathic intracranial hypertension in a child after hemodialysis.
Idiopathic intracranial hypertension remains a disease of unknown etiology. Epidemiology, associations, features, and prognosis in children have changed over the years. The main clinical complaint of pediatric idiopathic intracranial hypertension is headache with visual disturbance. We report on a patient with childhood idiopathic intracranial hypertension, who presented without headache after hemodialysis for acute renal failure. Idiopathic intracranial hypertension without headache is believed to have a poor prognosis. However, this child demonstrated a favorable outcome with medical therapy. The child was followed with serial optical coherence tomography of retinal nerve fiber layer thickness around the optic nerve head. In the absence of a reliable procedure to evaluate the therapeutic efficacy in the follow-up of patients with idiopathic intracranial hypertension, the importance of optical coherence tomography, a noninvasive, objective, and reproducible procedure, is highlighted as a useful adjunct in the management of idiopathic intracranial hypertension.

title: Epithelial ingrowth following surgery of recurrent pterygium
abstract: Epithelial ingrowth is a rare but devastating condition of the eye, known to complicate incisional ocular procedures. We report a case of secondary glaucoma due to epithelial ingrowth following limbal conjunctival autograft in a case of recurrent pterygium. To prevent such devastating conditions from occurring dissection of recurrent pterygium demands special care to avoid anterior chamber penetration.

title: Awareness of diabetic retinopathy among physicians and optometrists in a district of West Bengal.
abstract: A cross sectional study was done to ascertain the current knowledge among physicians and optometrists regarding diabetic retinopathy in a district of West Bengal. We obtained response from 242 physicians and 36 optometrists working in government health units. The questionnaire comprised of three sections covering magnitude of problem, risk factors and management. The responses were analysed and graded. In different sections, knowledge of 74 - 78% physicians and 83 - 86% optometrists was graded as not acceptable. Existing lack of knowledge among physicians and optometrists regarding diabetic retinopathy needs correction.

title: Correlation of macular thickness and posterior hyaloid change following bevacizumab and triamcinolone in diffuse diabetic macular edema in middle-aged patients
abstract: To compare changes in posterior vitreous detachment (PVD) following intravitreal injection of bevacizumab and triamcinolone in diffuse diabetic macular edema in middle-aged type 2 diabetes patients and to correlate this change with change in central macular thickness (CMT).  Fifteen consecutive patients treated by intravitreal bevacizumab (group A) and ten patients treated by intravitreal triamcinolone (group B). Institutional study carried out by retrospective analysis of patient registers including serial optical coherence tomography (OCT) images at baseline, and after 1 and 4 months. A central macular thickness (CMT) and vitreomacular relationship was noted on OCT. PVD was graded on a linear scale (0–4). Change in grade of PVD was correlated with change in CMT at each follow-up. At month 4, the decrease in mean CMT from baseline was 51.2 μ (P = 0.000) and 45 μ (P = 0.022) in group A and group B, respectively, with no significant difference between the two groups (P = 0.874). A change in grades of PVD from baseline to month 4 was significant in both group A (P = 0.001) and group B (P = 0.004) with no significant difference between the two groups (P = 0.906). A significant correlation between change in PVD and reduction of CMT was observed in group A (P = 0.011) but not in group B (P = 0.315). Both bevacizumab and triamcinolone caused a significant reduction in macular thickness and a significant change in grade of PVD. Change in PVD played an influential role in the reduction of macular thickness following bevacizumab.

title: Diagnostic accuracy in retinoblastoma.
abstract: This study was done to ascertain the accuracy of diagnosis and possible risk of misdiagnosis in suspected retinoblastoma cases by different pre-operative diagnostic procedures like fundoscopy, ultrasonography, computerised tomography, and aqueous cytology study. Twenty-four eyes excised with diagnosis of suspected retinoblastoma were included in the study. Final diagnosis was reached by histopathological examination of excised eyes and compared with pre-operative diagnosis by different diagnostic procedures and accuracy of each procedure was calculated. Twenty-two cases were finally diagnosed as retinoblastoma and 2 cases (8.33%) as other than retinoblastoma. Computerised tomography and aqueous humour cytology were two most specific (100%) tests. Computerised tomography was the most sensitive (95.4%) test. Aqueous cytology was poorly sensitive (9.09%). Both ultrasonography and fundoscopy demonstrated sensitivity over 90% but with low specificity (50%). When test results of fundoscopy and ultrasonography were combined, specificity of this combination was 100% and sensitivity was 95.4%, which match exactly the values of computerised tomography. Combination of fundoscopy and ultrasonography has accuracy as high as that of computerised tomography. In patients with clear media this combination can be used as an effective alternative to computerised tomography to reach a diagnosis with comparable accuracy.

title: Posthepatitis aplastic anaemia presenting only with bilateral vision loss.
abstract: Aplastic anaemia is pancytopenia with marrow hypocellularity. Hepatitis-associated aplastic anaemia is a varient or aplastic anaemia that follows an acute attack of seronegative hepatitis. Here a case of hepatitis-associated aplastic anaemia presenting with sudden onset of severe simultaneous bilateral vision loss and without any other usual presenting signs is reported. Partial recovery of blood cell count occurred following immunosuppressive therapy. Posterior hyalodotmy helped rapid resolution of premacular subhyaloid haemorrhage. Although bilateral vision loss may rarely be the initial presentation of aplastic anaemia, no such report is known in hepatitis-associated aplastic anaemia. Posthepatitis vision loss needs careful investigation to exclude an underlying haematological disorder.

title: Fatal Outcome Despite Full Lympho-Hematopoietic Reconstitution After Allogeneic Stem Cell Transplantation in Atypical Ataxia Telangiectasia
abstract: Allogeneic hematopoietic stem cell transplantation (HSCT) has not been a therapeutic option in ataxia telangiectasia (AT) due to overwhelming toxicity of conditioning in the context of the global DNA repair deficiency. Furthermore HSCT is unable to cure neurological involvement of AT. We report on a Turkish child with a Hyper IgM phenotype disorder, in which clinical aspects of AT were absent and thus, AT not diagnosed. He was transplanted with a reduced toxicity, but full intensity conditioning regimen comprising treosulfan, fludarabine and ATG. The peritransplant period was uneventful and the patient was discharged at day +57. 8 months after HSCT, the patient developed hepatopathy with monoclonal gammopathy of unclear significance and died due to hepatic failure and encephalopathy at the age of 32 months. Post mortem high throughput sequencing revealed a mutation in the ATM gene.

title: Patterns of spatio-temporal correlations in the neural activity of the cat motor cortex during trained forelimb movements
abstract: In order to study how neurons in the primary motor cortex (MI) are dynamically linked together during skilled movement, we recorded simultaneously from many cortical neurons in cats trained to perform a reaching and retrieval task using their forelimbs. Analysis of task-related spike activity in the MI of the hemisphere contralateral to the reaching forelimb (in identified forelimb or hindlimb representations) recorded through chronically implanted microwires, was followed by pairwise evaluation of temporally correlated activity in these neurons during task performance using shuffle corrected cross-correlograms. Over many months of recording, a variety of task-related modulations of neural activities were observed in individual efferent zones. Positively correlated activity (mainly narrow peaks at zero or short latencies) was seen during task performance frequently between neurons recorded within the forelimb representation of MI, rarely within the hindlimb area of MI, and never between forelimb and hindlimb areas. Correlated activity was frequently observed between neurons with different patterns of task-related activity or preferential activity during different task elements (reaching, feeding, etc.), and located in efferent zones with dissimilar representation as defined by intracortical microstimulation. The observed synchronization of action potentials among selected but functionally varied groups of MI neurons possibly reflects dynamic recruitment of network connections between efferent zones during skilled movement.

title: Upcoming and future strategies of tick control: a review.
abstract: Ticks are distributed worldwide and significantly impact human and animal health. Due to severe problems associated with the continuous use of acaricides on animals, integrated tick management is recommended. Increasing public health concern over the tick-borne diseases demands the strategic control of ticks on animals that transmit diseases to human beings. Immunological control of tick vector of Kyasanur Forest Disease (KFD) on cattle and other wild reservoir hosts is one of the possible alternative strategy for reducing the transmission of KFD to man. Chemical-vaccine synergies have been demonstrated and a combination of chemical and vaccine for tick and tick-borne disease control has been identified as a sustainable option. Studies have suggested the possibility of vaccine strategies directed towards both tick control and transmission of pathogens. Besides tick vaccine, use of endosymbionts, which are essential for the survival of arthropod hosts, for the control of tick vectors will be one of the targeted areas of research in near future. India with huge natural resources of herbs and other medicinal plants, the possibilities of developing herbal acaricides is discussed. The future of research directed towards target identification is exciting because of new and emerging technologies for gene discovery and vaccine formulation.

title: Remodeling of the antegonial angle region in the human mandible: a panoramic radiographic cross-sectional study.
abstract: This study analyzed changes in the antegonial region in relation to age, gender, and dental status.



A total of one thousand patients (five hundred males and five hundred females), who were prescribed panoramic radiograph for various purposes were included in the study. The patients were categorized according to age, gender and dentition status. Panoramic radiographs were traced and antegonial angles and depths were measured.



A trend of decrease in the antegonial angle and increase in antegonial depth with age was observed in both males and females. Furthermore there were differences between right and left side antegonial angle and depth, with left side angle more than right and right side depth more than left. There was a significant decrease in the values of antegonial angle and significant increase in the values of antegonial depth as the dentition status changed from completely dentulous to partially dentulous and from partially dentulous to completely edentulous state.



The antegonial angle decreases with the advancing age and thereby increases the antegonial depth. Similar trends are seen when teeth are lost. Furthermore there is an inherent asymmetry in the antegonial region in right and left side.

title: Management of Crohn’s disease from efficacy, quality of life and health economic perspectives
abstract: The expectations of the physician and patient in the modern management of Crohn’s disease have moved on from alleviation of symptoms whenever relapses occur, to sustained maintenance of remission and mucosal healing. The majority of treatment costs are as a consequence of hospitalizations and surgery. These heightened therapeutic goals are leading to expectations that management costs will decrease. Health-related quality of life can be measured by validated disease-specific tools in Crohn’s disease, and such measurements are now forming common outcome measures in clinical trials of new therapies in Crohn’s disease. This review gives an overview of patient-focused management of Crohn’s disease and the rapid evolution in therapy, with pharmacoeconomic analysis where available.
