Introduction: Occupational safety and health (OSH) is a crucial issue in the medical laboratory environment, considering the potential for exposure to various biological and chemical risks. The proper use of personal protective equipment (PPE) is one of the main pillars in mitigating this risk. Understanding the medicolegal implications related to the use of PPE is an important aspect that can influence laboratory staff compliance. This study aims to examine the relationship between understanding medicolegal implications and compliance with the use of PPE among laboratory staff at Indriati Boyolali Hospital.

Methods: This study used a cross-sectional observational design. The sample consisted of 120 laboratory staff at Indriati Boyolali Hospital who were selected randomly. Data was collected through structured questionnaires to measure the level of understanding of medicolegal implications and direct observation to assess compliance with PPE use. Data analysis was carried out using descriptive and inferential statistical tests (chi-square test and logistic regression).

Results: The research results showed that there was a significant relationship between understanding medicolegal implications and compliance with PPE use (p < 0.05). Laboratory staff with a better understanding of medicolegal implications tend to demonstrate higher levels of compliance in the use of PPE. Other factors such as age, gender, and work experience were also found to influence compliance with PPE use.

Conclusion: Understanding medicolegal implications is an important factor that contributes to compliance with the use of PPE among laboratory staff. Comprehensive educational interventions regarding medicolegal aspects of OSH can increase the understanding and awareness of laboratory staff, thereby contributing to improving occupational safety and health in the laboratory environment.

Fatal Blunt Severe Hemorrhagic Pancreatitis Trauma: A Case Report

2024-07-12T02:59:07+00:00

Introduction: Pancreatic trauma is a rare but potentially fatal condition. Blunt pancreatic trauma can lead to severe hemorrhagic pancreatitis, a life-threatening complication. This case report presents a fatal instance of blunt severe hemorrhagic pancreatitis resulting from an assault.

Case presentation: A 21-year-old male victim was found unconscious in a student dormitory after suffering multiple punches to the abdomen during an assault. Despite being rushed to the hospital, the victim succumbed to his injuries. A post-mortem examination revealed extensive bruising on the abdomen, along with internal injuries including cardiovascular enlargement, colonic vasodilation, and blood on the surface of the pancreatic tissue. Histological analysis of the pancreas showed severe necrosis, cytoplasmic necrosis, and widespread hemorrhagic hyperemia of the peripancreatic tissue. Toxicological tests for drugs, alcohol, and other substances were negative.

Conclusion: This case highlights the potential severity of blunt pancreatic trauma and the importance of prompt diagnosis and treatment. The retroperitoneal location of the pancreas can make diagnosis challenging, leading to delays in care and potentially fatal outcomes. In cases of suspected abdominal trauma, a thorough examination of the pancreas is crucial, including histological analysis if necessary. This case underscores the need for increased awareness of pancreatic trauma among healthcare professionals and the public.

Retinal Vascular Biometrics for Personal Identification in Forensic Investigations: A Pilot Study in the Palembang Population

2025-03-21T01:28:26+00:00

Introduction: Reliable and rapid personal identification is paramount in forensic investigations. Traditional methods can be time-consuming or challenging, particularly in cases involving fragmented remains or limited access to comparative data. Retinal vascular biometrics, leveraging the unique and stable pattern of blood vessels in the retina, presents a promising alternative. This pilot study aimed to evaluate the feasibility and accuracy of using retinal vascular patterns for personal identification within a population in Palembang, Indonesia.

Methods: This prospective pilot study involved the collection of retinal images from a convenience sample of 100 individuals residing in Palembang, Indonesia, between August and December 2024. Retinal images were captured using a non-mydriatic fundus camera model commonly available in ophthalmological clinics. Pre-processing steps included image enhancement and noise reduction. Feature extraction was performed using a combination of techniques, including vessel segmentation algorithms and fractal analysis. A matching algorithm based on normalized cross-correlation and feature vector distance was employed to compare retinal images. The performance of the biometric system was evaluated using metrics such as the False Acceptance Rate (FAR), False Rejection Rate (FRR), and Equal Error Rate (EER).

Results: The analysis of 10000 comparison attempts (100 genuine and 9900 imposters) yielded promising results. The calculated EER for the retinal vascular biometric system was 0.85%. The FAR at a 0% FRR was 0.1%, and the FRR at a 0% FAR was 1.6%. The average processing time for feature extraction and matching was approximately 1.5 seconds per comparison. Demographic analysis suggested no significant difference in accuracy across different age groups within the studied sample.

Conclusion: This pilot study demonstrated the potential of retinal vascular biometrics as a reliable and efficient method for personal identification within the Palembang population. The low EER suggests a high level of accuracy. Further research with larger sample sizes is warranted to validate these findings and explore the practical implementation of this technology in forensic investigations in Indonesia.
