Application of 3D Surface Scanners in Forensic Science and Medicine ( I ): Digital Storage of Human Skeletons and Development of Appraisal Methods for Incident Scenes / 대한법의학회지

The aim of this project was to use 3D scanning data collected at incident scenes and various evidence to 1) develop surveying methods based on 3D data consisting of overall and detailed scene evidence, captured by long-range and micros-canner, which can be shared by personnel working in different fields such as forensic medicine, video analysis, physical analysis, traffic engineering, and fire investigation; 2) create digital storage for human skeletons and set the foundation for virtual anthropology; and 3) improve the credibility of 3D evidence by virtual remodeling and simulation of incident scenes and evidence to provide a basis for advanced and high-tech scientific investigation. Two complete skeletons of male and female were scanned using 3D micro-scanner. Each bone was successfully reproduced and assembled in virtual space. In addition, recreating evidence scheduled for invasive examination by creating RP (rapid prototype) was possible. These outcomes could play an important role in setting up the new field of virtual anthropology. Case-specific surveying methods were developed through analysis of 3D scanning data collected by long-range surface scanners at the scenes of vehicular accidents, falls, shootings, and violent crimes. A technique and recording method was also developed for detecting forged seals by micro-scanning the pressure exerted on the seal. Appraisal methods developed in this project could be utilized to secure 3D data of human skeletal remains and incident scenes, create a standard for application, and increase objectivity, reproducibility, and accuracy of scanning methods. We plan to develop case-specific 3D data analysis techniques to improve the credibility of analysis at the NFS and to establish a 3D data collection and analysis team.

A Case of Ioslated TSH Deficiency / 대한내분비학회지

Although complete or partial deficiency of anterior pituitary hormone is well known,but isolated TSH deficiency is relatively rare throughout the world. Hypothyroidism due to isolated TSH deficiency is diagnosed by 1)symptoms or signs of thyroid deficiency, 2)demonstration of an absent or impaired TSH response to TRH stimulation, 3)intact other pituitary hormones. We report a case of hypothyroidism due to isolated TSH deficiency. The patient was 75 years old man and his complaints were generalized edema and weight gain. On laboratory study, T3, T4, TSH was low and TSH response to TRH stimulation was blunted, but other piutuitary hormones were intact. After thyroxine replacement, TFT and his symptoms were recovered.

A case of acute coma & respiratory arrest in Wernicke's encephalopathy caused by malnutrition / 대한내과학회지

We shoud give attention to Wernicke's encephalopathy as a cause of sudden coma & respiratory arrest in patients, who are not usually suspected to develop the disorder and empirical treatment with thiamine in cases of coma of unknown cause is recommended. Respiratory stimulants, doxapram & aminophylline have an effect in assisting ventilatory weaning in patient with central hypoventilation as a complication of acute Wernicke's encephalopathy No previous reports where doxapram had been used to assist weaning from mechanical ventilation in adults were noted. Nor has newly developed central hypoventilation been identified as an impediment to weaning in literature to date in Korea. We reported a rare case of Wernicke's encephalopathy caused by poor oral intake & inadequate nutritional suppliment after car accident, showing acute coma & respiratory arrest and treated adequately by thiamine replacement & mechanical ventilation with respiratory stimulant.

A Case of Isolated ACTH Deficiency Manifestated by Atrial Fibrillation and Hypoglycemia / 대한내분비학회지

Isolated ACTH deficiency is a rare cause of secondary adrenocortical insufficiency caused by the defect of synthesis or release of ACTH in pituitary gland. The clinical presentation can be simiilar to that of primary adrenal insufficiency, but there is a greater tendency for hypoglycemia and absence of hyperpigmentation. The patient, 80 year-old female, was admitted in chief complaint of deteriorated mental states. On admission, serum sodium was 127mEq/L, potassium 4.4mEq/L, blood glucose 27mg/dL and on routine E.C.G. was atrial fibrillation was revealed. The basal morning serum cortisol level was 9.97 pg/dL it dosent respond to insulin-induced hypoglycemia enoughly, but other pituitary functions were intact in pituitary cocktail stimulation test. In CRH stimulation test, there was no remarkable response in serum ACTH and cortisol level. Brain MRI failed to reveal any anatomic abnormalities of the sellar or suprasellar area consistent with the defect of pituitary ACTH secretion. This case was a isolated ACTH deficiency, So, we conclude that associated with atrail fibrillation and hypoglycemia.
