Sexual dimorphism and topological variability in fingerprint ridge density in a north-west Indian population.

The science of fingerprints is very crucial in criminal investigation as it helps identify perpetrators or victims of a crime. Fingerprint ridge density (FPRD), which refers to the number of ridges within a specific area on the epidermal skin layer of the distal phalanges in humans, has been found to differ between males and females. This study attempts to estimate the sex from FPRD and evaluates the diversity in FPRD across several topological areas. The study involves 208 participants (120 males, 88 females) between the ages 18 to 25 years from a North-west Indian population. Fingerprints were collected, and FPRD was accessed in radial, ulnar, and proximal areas as recommended by Gutierrez-Redomero et al. (Forensic Sci Int 180(1):17-22, 2008). FPRD has been quantified using the techniques described by Acree (Forensic Sci Int 102(1):35-44, 1999). When evaluating FPRD in the lateral pocket loops and twin loops, the proximal-side core was considered. The study reveals that males have a mean fingerprint ridge density of 12.82 ridges/25 mm2 while females have 13.01 ridges/25 mm2. Females have higher fingerprint ridge density solely in the proximal area; males have higher fingerprint ridge density in both radial and ulnar areas. In conclusion, this research underscores the potential of fingerprint ridge density as a parameter for investigating population variations and individual identification. Future studies on fingerprint ridge density in India's diverse population will help establish reference ranges, allowing for sex and likely population group estimation, making it a valuable tool for preliminary examinations and exclusion criteria for sex estimation in crime scene investigations.

Awareness regarding risks of self-medication among people visiting community pharmacies.

A cross-sectional survey was conducted from April 2018 to February 2019 to assess the level of awareness regarding the risks of self-medication among people visiting the community pharmacies of Block-13, Gulistan-e-Johar, Karachi. Data was collected from 395 participants after taking their written informed consent by using a pre-tested questionnaire and analysed on statistical package for social sciences version 20. The study results showed that 186 (47.1%) participants were aware that drugs have side-effects, 242 (61.3%) knew that a drug can make a person dependent on it, 220 (55.7%) had the knowledge that long-term use of any medicine can be harmful to the body, 132 (33.4%) were aware that all over-the-counter medicines are not safe to use, whereas178 (45.1%) believed that no medicine should be taken unless recommended by a licensed practitioner. It was concluded that many of the study participants did not have the knowledge regarding risks of self-medication.
