    The importance of hemosiderin deposition in the infant brain: an autopsy study
    (Lithographia, 2015) Inanir, Turkmen N.; Eren, F.; Akgoz, S.; Eren, B.; Cetin, S.; Gundogmus, U. N.; Comunoglu, N.
    Background/aim: Iron is an essential element involved in many metabolic processes. Presence and accumulation of iron in various body systems can result in different outcomes. Its accumulation in the central nervous system (CNS) cannot be detected routinely by application of hematoxylin-eosin staining. Detection of the presence of hemosiderin in the brain and cerebellum by application of Perls' dye is of importance in cases of infant deaths. Material and Methods: In this study, brain and cerebellar specimens obtained from 52 eligible infants (aged 0-1 years) autopsied in our institute between the years 2010 and 2013, independent of the cause of death, were analyzed in order to detect possible presence of hemosiderin. Perls' dye was used to detect histopathological staining intensity and distribution of hemosiderin in the brain and cerebellum. Results: Cases did not differ significantly as for the patients' age and gender (p = 0.473), type of the culprit trauma (p = 0.414), death/crime scene (p = 0.587), and diagnosis groups (p = 0.550). In this autopsy study blue colored hemosiderin granulations, stained with Perls' dye were detected in the brain (n: 39, 75%), and cerebellum (n: 35, 67.3%). A weakly negative, but significant correlation was detected between the postmortem interval and intensity values of cerebellar hemosiderin (Spearman's correlation coefficient: -0.381, p = 0.024). A statistically significant difference was found between the distribution scores of cerebral hemosiderin in cases with and without trauma history (p = 0.03). Median cerebral hemosiderin distribution scores were 2.5 and 2, respectively. Conclusions: The detection of a correlation between the presence of cerebral and cerebellar hemosiderin, and post-mortem interval in the age group of 0-1 years, should be interpreted as an important finding in the analysis of cerebral iron. The presence of hemosiderin in the CNS may be a significant finding in the elucidation of infant deaths and this procedure should be carried out on a routine basis.

    The risk factors for mortality in elderly patients with hip fractures: postoperative one-year results
    (Singapore Medical Assoc, 2010) Ozturk, A.; Ozkan, Y.; Akgoz, S.; Yalcyn, N.; Ozdemir, R. M.; Aykut, S.
    Introduction: Hip fractures in the elderly are associated with significant mortality. This study aimed to investigate the risk factors for mortality in elderly patients with hip fractures during a one-year period. Methods: This was a prospective study which included consecutive isolated nonpathologic hip fractures in 74 (52 female, 22 male) patients in a level-1 trauma centre. These patients were 65 years or older and were ambulatory before the fracture. The patients were treated with hemiarthroplasty. The factors investigated were age, gender, nutritional status determined by blood albumin and total lymphocyte count, haemoglobin levels on the day of admission, mobilisation time after surgery, length of hospital stay, comorbidities, American Society of Anaesthesiologists (ASA) rating of operative risk, and the time period between injury and surgery. The patients were followed up for one year after surgery, or until death. Results: In total, 15 patients died during the one-year period. Patient survival was 94.6 percent at 3 months, 81.1 percent at 6 months and 79.7 percent at 12 months. There were two in-hospital deaths. The factors significantly associated with mortality were patients with more than two comorbidities, an ASA score of III-IV, a blood albumin level of less than 3.5 g/dl and a total lymphocyte count of less than 1500 cells/ml on admission. Hovewer, after the multivariate analysis, an ASA score of III-IV, low total lymphocyte count, female gender and low haemoglobin levels on admission remained the independent and significant risk factors associated with a one-year mortality. Conclusion: This study confirms that a high ASA score, female gender, a lower lymphocyte count and low haemoglobin levels on admission are significant factors in assessing the one-year mortality in elderly patients with hip fractures. Predicting these risk factors improves the case management.
