CLINICO-PATHOLOGICAL CORRELATION IN NEONATAL AUTOPSIES

Of the 253 neonates admitted to a neonate intensive care unit during the period Jan 91 to Sep 93, 43 neonates died. Autopsy was done in 23 of these (53%). The mean duration of stay of the neonates in the intensive care unit prior to death was 5.6 days (range 2 hours to 10 days). Antemortem diagnoses included asphyxia neonatorum (4), meconium aspiration syndrome (2), septicemia (5), prematurity (3), birth trauma (2), congenital anomalies (2), hypoxic ischemic encephalopathy (1), and non-specific diagnosis (4). There were 6 major autopsy findings that, if known prior to death, would have altered clinical management and might have resulted in cure or prolonged survival. There were 8 additional major findings that, if known prior to death, would not have altered management There were 14 minor findings related to major diagnoses but unrelated to the primary cause of death.KEY WORDS: Autopsy, Cause of death, Perinatal mortality

A PATHOLOGICAL STUDY OF BENIGN AND MALIGNANT TUMOURS OF SALIVARY GLANDS

Interest in the knowledge of salivary gland tumours is highlighted. A sample of 315 cases, collected over a period of 25 years in a busy pathology centre, is analysed both on total and individual aspects of tumours. The findings are compared to earlier works on the subject and also with contemporary literature.KEY WORDS: Pathological study, Salivary tumours     

Clinical patterns of congenital ocular anomalies in the pediatric age group (0 to 5 years) and its association with various demographic parameters

Purpose:Congenital ocular anomalies are rare but important cause of childhood blindness. This study aimed to observe the clinical patterns of congenital ocular anomalies in the pediatric age group (0 to 5 years) and its association with various demographic parameters.Methods:Hospital-based cross-sectional study done on all pediatric patients in the 0-to-5-year age group presenting with congenital ocular anomalies to the Ophthalmology department of a tertiary care hospital in Eastern India between October 2018 and October 2020. Thorough clinical history was obtained, and comprehensive ocular examination was done in each case.Results:A total of 5686 patients in the 0 to 5 years age group attended the eye OPD during the study period. Congenital ocular anomalies were seen in 140 patients. The prevalence of ocular anomalies was 2.46%. Average age of patients was 3.32 ± 1.42 years. There were 74 (52.9%) males and 66 (47.1%) females. Unilateral and bilateral involvement was seen in 100 (71.45%) and 40 (28.6%) cases, respectively. Antenatal period was uneventful in 92.14% cases. Decreased vision was the most common presentation (40%). Congenital nasolacrimal duct obstruction was the most common anomaly seen in 29 (20.71%) cases followed by congenital cataract in 21 (15%) cases.Conclusion:Few of the congenital ocular anomalies can be prevented by increasing community awareness. Findings of the study can act as a reference guide for clinicians and health professionals for counseling and health planning.     

In vitro antiprotozoal activity of some xanthones isolated from the roots of Andrographis paniculata

Four xanthones isolated from the roots of Andrographis paniculata were tested in vitro for antiprotozoal activity against Trypanosoma brucei brucei, Trypanosoma cruzi and Leishmania infantum. Compound TDR13011 (1,2-dihydroxy-6,8-dimethoxy-xanthone) showed good activity against T. b. brucei and L. infantum with a 50% inhibitory concentration (IC50) of 4.6 microg/ml and 8 microg/ml respectively. Xanthones from the roots of Andrographis paniculata exhibited promising anti-protozoal activity and these compounds could be chemically modified to obtain a more potent product.     

The Role of Facial Feedback in the Modulation of Clinically-Relevant Ambiguity Resolution

Two experiments investigated the effect of facial expressions on clinically-relevant ambiguity resolution in a nonclinical sample. Experiment 1 investigated the effect of negative facial feedback (frowning) on a basic threat-interpretation bias procedure using a homophone spelling task and found that participants in a frowning condition interpreted significantly more threat/neutral homophones as threats than did participants in a neutral control condition. Experiment 2 investigated how frowning affected interpretation of bodily sensations. The findings indicated that participants in the frowning condition generated fewer positive consequences for bodily sensation scenarios and also rated the imagined bodily sensations as more negative and more of a cause for health concern. These effects could not simply be explained by differences in self-reported mood or by demand characteristics. These findings suggest that facial expressions have a moderating effect on the cognitive processes that contribute to clinically-relevant ambiguity resolution, and this has implications for clinical interventions.
