This study attempted to discuss the historical context and current practice of forensic medicine in South Asia. Comparisons within and between countries in South Asia, and between South Asia and the developed countries (represented by Japan and the USA) have been made to provide an insight into their distinct practice of forensic medicine. Though the formal establishment of forensic medicine in South Asia commenced at a comparable period to the developed countries, their pace of development has been considerably slow. Moreover, their ways of practice as well have evolved differently. In effect, South Asian countries follow an 'integrated service' system, whilst Japan and the USA practice 'divided service' systems to provide forensic medical services. Similarly, regarding the death investigations, most South Asian countries follow a Police-led death investigation system, whereas Japan and the USA follow a hybrid model and the Medical examiner's system of death investigation, respectively. Indeed, forensic medicine in South Asia is undeniably underdeveloped. In this paper, by highlighting the issues and challenges confronted in South Asia, key actions for prompt redressal are discussed to improve the standard of forensic medical services in South Asia.

Background Intracardiac hypostasis is frequently observed in postmortem computed tomography (PMCT) of acute deaths, and it becomes clearer as the postmortem interval increases. To determine the postcardiac arrest interval (PCAI), we evaluated densities of the right and left atria [anterior part of the right atrium (AR) and posterior part of the left atrium (PL)] using postmortem computed tomographic images. Methods A total of 184 patients were included in the study. Patients with return of spontaneous circulation and those with final alive confirmation time over 1 hour were excluded. We evaluated the density of AR and PL at the level of the right inferior pulmonary vein entry to the left atrium. We defined the interval between the estimated cardiac arrest time and the postmortem CT time as the PCAI. Results There was a negative correlation between AR and PCAI in 59 patients who died owing to cardiovascular disease. The regression equation (PCAI = −1.725 × AR + 132.95) was obtained based on this result. There was no correlation between PL and PCAI. ConclusionThe result suggests that the density of the anterior part of the right atrium decreases as postcardiac arrest interval increases in the case of cardiovascular disease. The regression equation may be used as an additional method to estimate postcardiac arrest interval.

Background Paravertebral compartment syndrome occurring without trauma is quite rare. We report a case of compartment syndrome that occurred after spinal exercises. Case presentation A 23-year-old Japanese rower developed severe back pain and was unable to move 1 day after performing exercises for the spinal muscles. Initial evaluation at a nearby hospital revealed hematuria and elevated creatine phosphokinase levels. He was transferred to our hospital, where magnetic resonance imaging revealed no hematoma but confirmed edema in the paravertebral muscles. The compartment pressure measurements were elevated bilaterally. Despite his pain being severe, his creatine phosphokinase levels were expected to peak and decline; his urine output was normal; and surgery was undesirable. Therefore, we opted for conservative management. The next day, the patient’s compartment pressure diminished, and his pain levels decreased to 2/10. After 5 days, he was able to walk without medication. Conclusions We present a rare case of compartment syndrome of the paravertebral muscles with good resolution following conservative management. We hope our case findings will help avoid unnecessary surgery in cases of paravertebral compartment syndrome.

Spinal epidural abscess (SEA) is a rare condition, and a delay in its diagnosis causes paralysis. In this study, we report two rare cases of delayed diagnosis of SEA whose conditions improved after a state of complete paralysis. The first case was a 71-year-old diabetic man who received a corticosteroid injection for shoulder pain that caused intensified pain. Thereafter, the patient developed paralysis of both legs in stage IV according to Heusner staging. Subsequently, he was diagnosed with multiple abscesses and sepsis. He was in a poor state of health. Therefore, we treated his epidural abscess conservatively. After a month, his muscle strength had improved to Heusner stage III-A, and he was transferred to another hospital. The second case was a 64-year-old diabetic man who received an epidural corticosteroid injection for lower back pain. However, the pain intensified and was admitted to the hospital for pyelonephritis. He developed paralysis in both of his arms and legs presenting as a Heusner stage IV, caused by a cervical epidural abscess. A laminoplasty was performed and paralysis was improved. However, the patient subsequently developed a left subcortical hemorrhage. He underwent surgery. However, his right hemiplegia persisted, and on Day 21, he was transferred back to the previous hospital with a Heusner III-A. We could improve the patients' paralysis by cooperating closely with infectious disease specialists and spine surgeons, taking intensive care, applying antibacterial agents appropriately, and operating quickly.
