BackgroundThere are 44 million missing women in India. Gender bias; neglect of girls, infanticides and feticides are responsible. The sex ratio at birth can be used to examine the influence of antenatal sex selection on the sex ratio.Materials and MethodsRecords from 321,991 deliveries at one hospital over 11 decades were utilized. The middle year in each decade was taken as representative of the decade. Data from 33,524 deliveries were then analyzed. Data for each decade was combined with that of previous decades and compared to the data of subsequent decades to look for any change in the trend. Sex ratio in the second children against sex of the first child was studied separately.ResultsThe mean sex ratio for the 110 years examined was 910 girls to 1000 boys (95% CI; 891 to 930). The sex ratio dropped significantly from 935 (CI: 905 to 967) before 1979, to 892 (CI: 868 to 918) after 1980 (P = 0.04). The sex ratio in the second child was significantly lower if the first child was a girl [716 (CI: 672 to 762] (P<0.001). On the other hand, there was an excess of girls born to mothers whose first child was boy [1140 girls per 1000 boys (CI: 1072 to 1212 P<0.001)].ConclusionsThe sex ratio fell significantly after 1980 when ultra sound machines for antenatal sex determination became available. The sex ratio in second children if the first was a girl was even lower. Sex selective abortions after antenatal sex determination are thus implicated. However data on second children especially the excess of girls born to mothers who have a previous boy seen in the decade before the advent of antenatal ultra sound machines, suggests that other means of sex selection are also used.

BackgroundRefractive status at birth is related to gestational age. Preterm babies have myopia which decreases as gestational age increases and term babies are known to be hypermetropic. This study looked at the correlation of refractive status with birth weight in term and preterm babies, and with physical indicators of intra-uterine growth such as the head circumference and length of the baby at birth.MethodsAll babies delivered at St. Stephens Hospital and admitted in the nursery were eligible for the study. Refraction was performed within the first week of life. 0.8% tropicamide with 0.5% phenylephrine was used to achieve cycloplegia and paralysis of accommodation. 599 newborn babies participated in the study. Data pertaining to the right eye is utilized for all the analyses except that for anisometropia where the two eyes were compared. Growth parameters were measured soon after birth. Simple linear regression analysis was performed to see the association of refractive status, (mean spherical equivalent (MSE), astigmatism and anisometropia) with each of the study variables, namely gestation, length, weight and head circumference. Subsequently, multiple linear regression was carried out to identify the independent predictors for each of the outcome parameters.ResultsSimple linear regression showed a significant relation between all 4 study variables and refractive error but in multiple regression only gestational age and weight were related to refractive error. The partial correlation of weight with MSE adjusted for gestation was 0.28 and that of gestation with MSE adjusted for weight was 0.10. Birth weight had a higher correlation to MSE than gestational age.ConclusionThis is the first study to look at refractive error against all these growth parameters, in preterm and term babies at birth. It would appear from this study that birth weight rather than gestation should be used as criteria for screening for refractive error, especially in developing countries where the incidence of intrauterine malnutrition is higher.

Term babies are known to be hypermetropic, and preterm babies with retinopathy of prematurity (ROP) are known to have myopia. This study provides data on the mean spherical equivalent, the degree of astigmatism, and incidence of anisometropia at different gestational ages. This is the largest study in world literature looking at refractive errors at birth against gestational age. It should help understand the norms of refractive errors in preterm babies.

Objective:To study the clinical, pathological and prognostic profile of patients with temporal arteritis in India.Materials and Methods:The study was conducted in a tertiary care center from south India from 2005 to 2010 in the departments of neurology and medicine. The details of all patients that satisfied the ACR 1990 criteria for diagnosis of temporal arteritis were reviewed. The clinical presentation, laboratory parameters and biopsy findings of the patients were analyzed and compared with other studies from India done over the last decade.Results:A total of 15 patients were diagnosed with temporal arteritis. The male:female ratio was 1.5:1. The mean age of onset was 67.58 years. Mean time for detection after onset of symptoms was 2.56 months. Typical manifestations included headache (100%), temporal artery tenderness (100%), jaw claudication (20%), polymyalgia rheumatica (53%) and visual manifestations (20%). The erythrocyte sedimentation rate was elevated in all patients. Biopsy was done in 13 patients, with 11 of them being positive. All patients responded to steroids well, with most patients being symptom-free within the first 48 h of treatment.Conclusions:Temporal arteritis seems to be underdiagnosed in India, with all patients previously misdiagnosed, and with a mean time from symptom onset to diagnosis of 2.5 months. The clinical presentation of temporal arteritis in India appears to be similar to that of the West, with no gender preference and a slightly younger age group.

Somnambulism (sleepwalking) is a disorder of arousal that falls under "parasomnia" group and is more common in children. These phenomena occur as primary sleep events or secondary to systemic disease or can be drug induced. Medications that can cause sleepwalking include neuroleptics, hypnotics, lithium, amitriptyline, and β-blockers. This report presents an unusual adverse effect of topiramate on sleep in a patient with migraine.
