RESUMO
Empathy deficit is a core feature of schizophrenia which may lead to social dysfunction. The present study was carried out to investigate functional and structural abnormalities associated with empathy in patients with schizophrenia using functional magnetic resonance imaging (fMRI) and voxel-based morphometry (VBM). A sample of 14 schizophrenia patients and 14 healthy control subjects matched for age, sex and education were examined with structural highresolution T1-weighted MRI; fMRI images were obtained during empathy task in the same session. The analysis was carried out using SPM8 software. On behavioural assessment, schizophrenic patients (83.00±29.04) showed less scores for sadness compared to healthy controls (128.70±22.26) (p<0.001). fMRI results also showed reduced clusters of activation in the bilateral fusiform gyrus, left lingual gyrus, left middle and inferior occipital gyrus in schizophrenic subjects as compared to controls during empathy task. In the same brain areas, VBM results also showed reduced grey and white matter volumes. The present study provides an evidence for an association between structural alterations and disturbed functional brain activation during empathy task in persons affected with schizophrenia. These findings suggest a biological basis for social cognition deficits in schizophrenics.
RESUMO
Trigeminal neuralgia is sudden, usually unilateral, severe, stabbing, brief recurrent pain in the distribution area of one or more of the branches of trigeminal nerve. Various pharmacological agents including carbamazepine, oxcarbazepine, phenytoin, lamotrigine, baclofen and clonazepam have been tried with variable success rate. Here a case of idiopathic trigeminal neuralgia is presented. The patient presented in the emergency room with severe pain in the distribution area of maxillary branch of trigeminal nerve, resistant to conventional pharmacotherapy, managed successfully with gabapentin without untoward side-effects.

Nappy rash is a common problem in infants due to their thinner skin, wetness, heat and friction under cloth nappy, fecal enzymes and alkaline urine. The disposable diapers containing Super Absorbent Material (SAM) reduce the incidence of nappy rash. SAM quickly absorbs urine and keeps the skin dry. Also disposable diapers prevent fecal contamination by absorbing the urine and containing stools.

To find out the incidence of self-extubation in intensive care, to evaluate the factors responsible for it and to identify the predictors of need for re-intubation, a retrospective analysis was conducted among 350 patients who were admitted to the intensive care unit over a two-year period and required ventilatory therapy for more than 48 hours. In all patients who self-extubated, the demographic data, ventilatory parameters before self-extubation (mode of ventilation, inspired oxygen concentration, positive end-expiratory pressure), partial pressure of oxygen in arterial blood and inspired oxygen fraction ration (PaO2/FiO2), and the event of re-intubation were noted. These values were compared among patients who were re-intubated and those who were not. Twelve patients out of 350 self-extubated. Of these 12 patients, 7 required re-intubation while 5 did not. Of these 7 patients, 3 died within 48 hours of the episode of self-extubation and one patient's death was directly attributable to self-extubation. Of the remaining 4 patients, 3 died within a span of 7 days. Re-intubation after self-extubation should not be considered mandatory. Patients who required re-intubation had lower PaO2/FiO2 than patients who did not.
