Revision of the medicolegal assessment criteria in hypovolemic patients.

Trauma scoring systems are often used for the determination of the severity level of the lesion and the clinical status in medico-legal assessment of the trauma patient. Trauma scoring systems are used also for the determination of the life-threatening conditions. Blood loss of more than 20% was reported as the only criterion for life-threatening conditions in the acute hypovolemia. The objective of this study was to revise the medico-legal assessment criteria in the patients with acute hypovolemia and to discuss other parameters, which might be used in the determination of the severity level of the clinical status.The medical reports of the patients with acute hypovolemia due to the trauma, which were sent by the judicial authorities and by other departments of our medical faculty to the department of the forensic medicine between 1999 and 2009, were evaluated. The characteristics such as age, gender, severity of the injury, type of the trauma, history of liquid replacement or blood transfusion, vital signs, type of the physical injury, injured region of the body, presence of any chronic disease were assessed and recorded.The mean age of the included 155 patients was 34.70 ±â€Š16.08 years (3-87 years). 118 (76%) of patients were males and 37 females (24%). Regarding the event types, road accidents were the most common cause (60.0%) and it was followed by sharp object injuries (18.7%) and firearm injuries (11.6%). 27.7% of the subjects received 2 units blood and blood products transfusion and 21.3% only 1 unit transfusion. According to the results of the medico-legal assessment, 84.5% of the patients had life-threatening conditions.While evaluating the severity of the clinical conditions in the hypovolemic patients, to report only the losses in percentage causes problems and limitations. Therefore, in respect of the medico-legal assessment of the hypovolemic patients, we believe that it would be more appropriate to use the physiological trauma scoring systems (like Revised Trauma Score) instead of the anatomic scoring systems.

Prevalence of Pneumocystis jirovecii colonization in autopsy cases in Turkey.

Detection of Pneumocystis jirovecii and its DNA in clinically asymptomatic people is defined as colonization. The aim of this study was to reveal the colonization prevalence of P. jirovecii and affecting factors in an immunocompetent population. The study included 200 cases undergoing forensic autopsy between February 2015 and April 2015. The cause of death was non-medical conditions (group 1) in 111 cases (55.5 %), medical conditions (group 2) in 73 cases (36.5 %) and undetermined (group 3) in 16 cases (group 3). Tissue specimens about 1 g in weight were taken from the right upper pulmonary lobe. After DNA extraction, nested PCR targeting mitochondrial large subunit rRNA was used to detect P. jirovecii. Of 200 cases, 37 (18.5 %) had P. jirovecii DNA. There was not a significant difference in place of living, gender, smoking status and medication use between the cases with P. jirovecii and those without P. jirovecii. A significantly high rate of P. jirovecii colonization was detected in group 2 (χ²=7.674; P=0.022). P. jirovecii-colonized cases also had a chronic disease in 2 of 13 (group 1), 12 of 20 (group 2) and 1 of 4 (group 3) cases (χ²=5.571; P=0.062). A significantly high rate of the cases aged 0-1 year had P. jirovecii (5/11; 45.5 %) (χ²=5.639; P=0.018). The results of the study suggest that infants and patients with chronic diseases like cardiac or pulmonary diseases can be at risk for P. jirovecii colonization.

The Anatomy of Circulus Arteriosus Cerebri (Circle of Willis): A Study in Turkish Population.

AIM: The function of the circle of Willis, an arterial polygon, is to protect the brain from ischemia. The aim of this study is to define the structural characteristics of the circle of Willis within the Turkish adult population, along with variations and arteries involved in the measurement of diameters and lengths on cadavers. MATERIAL AND METHODS: The circle of Willis was evaluated in 100 fresh adult cadavers. Structures of the circle of Willis were evaluated as being typical or atypical images and according to the diameter of AComP. All arteries forming the circle's length and diameters were measured. RESULTS: All arteries forming the circle of Willis as 91% were anatomically observed. The typical structure in which hypoplasia arteries is not involved was obtained as 8%. The atypical circle of Willis with aplasia was seen as 9%. 87% of adult, 9% fetal, and 4% transitional configuration in the samples were detected. The variations of the circle of Willis were more common in the posterior portion. Hypoplasia was found to be the most common variation and noted as a maximum in AComP (85%). Aplasia was noted as the second most common variation after hypoplasia and again the most common in AComP (5%). CONCLUSION: Advances in radiological methods which provide images of cerebral vessels and the development of cerebrovascular surgery have increased the importance of the circle of Willis in neurosurgery and neurology. The structure of the circle of Willis is of great importance in occlusive cerebrovascular diseases and cerebrovascular surgery.
