Yeungnam University Journal of Medicine 2002;19(2):136-143
Even though the nonketotic hyperglycemia is a metabolic disorder, it complicates hemic- horea-hemiballism rarely. Moreover, generalized chorea-ballism associated with nonketotic hyperglycemia in diabetes mellitus is very rare, so it has not been reported in Korean literature. Although the precise pathophysiologic mechanisms of these disorders are still poorly understood, deficiency of gamma aminobutyric acid (GABA) in nonketotic hyperglycemia or reduced GABAnergic inhibition by striatal lesion may increase inhibitory output to subthalamic nucleus. These result loss of pallidal inhibition and produce contralateral hemichorea-hemiballism. The striatal lesions, such as transient ischemia with reactive astrocytosis or small amount of petechial hemorrhage, are related with changes of magnetic resonance image (MRI) findings presumably. We report a diabetic old woman who developed generalized chorea-ballismus as a very rare complication of nonketotic hyperglycemia. Her brain MRI showed high signal intensity in left lentiform nucleus and right pallidum on T1 weighted images and low signal intensity in bilateral putamen on T2 weighted images with highly enhanced corresponding lesions on T1 weighted enhancement images.

2.Microleakage of the experimental composite resin with three component photoinitiator systems.
Journal of Korean Academy of Conservative Dentistry 2009;34(4):333-339
This study was done to determine if there is any difference in microleakage between experimental composite resins, in which various proportions of three component photoinitiators (Camphoroquinone, OPPI, Amine) were included. Four kinds of experimental composite resin were made by mixing 3.2% silanated barium glass (78 wt.%, average size; 1 microm) with each monomer system including variously proportioned photoinitiator systems used for photoinitiating BisGMA/BisEMA/TEGDMA monomer blend (37.5:37.5:25 wt.%). The weight percentage of each component were as follows (in sequence Camphoroquinone, OPPI, Amine): Group A - 0.5%, 0%, 1% / Group B - 2%, 0.2%, 2% / Group C - 0.2%, 1%, 0.2% / Group D - 1%, 1%, 2%. Each composite resin was used as a filling material for round class V cavities (diameter: 2/3 of mesiodistal width; depth: 1.5 mm) made on extracted human premolars and they were polymerized using curing light unit (XL 2500, 3M ESPE) for 40 s with an intensity of 600 mW/cm2. Teeth were thermocycled five-hundred times between 50degrees C and 550degrees C for 30s at each temperature. Electrical conductivity (microA) was recorded two times (just after thermocycling and after three-month storage in saline solution) by electrochemical method. Microleakage scores of each group according to evaluation time were as follows [Group: at first record / at second record; unit (microA)]: A: 3.80 (0.69) / 13.22 (4.48), B: 3.42 (1.33) / 18.84 (5.53), C: 4.18 (2.55) / 28.08 (7.75), D: 4.12 (1.86) / 7.41 (3.41). Just after thermocycling, there was no difference in microleakage between groups, however, group C showed the largest score after three-month storage. Although there seems to be no difference in microleakage between groups just after thermocycling, composite resin with highly concentrated initiation system or classical design (Camphoroquinone and Amine system) would be more desirable for minimizing microleakage after three-month storage.

We report a case of primary cutaneous cryptococcosis on the left knee of a 67 year-old woman. She had a large ulcerated and indurated plaque with yellowish purulent exudates on her left knee. A histopathological examination from the lesion showed numerous encapsulated, round spores. Cultures from the lesion showed the presence of Cryptococcus neoforrnans. This may have resulted from an immunosuppressive state due to long-term use of oral corticosteroids.

BACKGROUND: We summarize our experience in the pathological diagnosis of late complications of liver transplantation (LT) to better understand the causes of late allograft dysfunction in a population mostly composed of patients with hepatitis B virus (HBV) infection. METHODS: We reviewed 361 post-transplant liver biopsies from 174 patients who underwent LT and first presented with liver function abnormalities 3 months post-procedure. The underlying diseases included HBV-associated liver disease (77%), toxic or alcoholic liver disease (10.3%), hepatitis C virus (HCV)-associated liver disease (8.6%), primary biliary cirrhosis (1.2%), primary sclerosing cholangitis (1.2%), and metabolic disease (1.7%). RESULTS: The three most common late complications were acute rejection (32.5%), recurrent disease (19.1%), and biliary complication (17.1%). Patients who underwent LT for HBV infection or for drug- or alcohol-related liver disease had a lower incidence of recurring disease than those who underwent transplantation for HCV infection. During post-transplantation months 3-12, acute rejection was the most common cause of allograft dysfunction and recurring disease was the leading cause for allograft dysfunction (p=0.039). The two primary causes of late allograft dysfunction have overlapping histological features, although acute rejection more frequently showed bile duct damage and vascular endothelialitis than recurring HBV infection, and recurring HBV infection had more frequent lobular activity and piecemeal necrosis. CONCLUSIONS: The causes of late liver allograft dysfunction are closely associated with the original liver diseases and the period after LT. Careful attention is required for differential diagnosis between acute rejection and recurrent HBV.

We assessed about growth hormone binding proteins (GHBP) activity which was measured eluted biotin GH fraction with alkaline phosphatase-streptavidine in children with insulin dependent diabetes mellitus (IDDM), short stature due to growth hormone deficiency (GHD), chronic renal failure, short stature due to nutritional deficiency. hypothyroidism and normal control groups using high pressure liquid chromatography protein pak 300 sw column. The following results are observed: 1) There were 3 types of growth hormone (GH) in serum: first GH binded with type I (minor) GHBP suggesting 200K dalton of molecular weight, second GH binded with type II (major) GHBP suggesting 60~70K dalton of molecular weight, and third GH were free form GH suggesting 20~25K dalton of molecular weight. 2) Type II (major) GHBP showed considerable individual variation in all ages. Neonates had the lowest levels of GHBP activity, but by the puberty the levels had increased & remained stable from adolescent to adult periods. 3) GHBP activity of children with IDDM at diagnosis was low value as compared to the same agenormal control group (p<0.05), and difference of GHBP activity among children with IDDM was related with height velocity (r=+0.92). Follow up GHBP activity during insulin therapy was reverse correlation with HbAlc. 4) GHBP activity of children with GHD at diagnosis was a slightly low compared to aged matched control and follow-up GHBP activity after 1 dose GH therapy showed increasing tendency (r=-0.68). 5) Otherwise, children with chronic renal failure, short stature due to nutritional deficiency, and hypothyroidism were assessed lower value than normal control group. Above results, GHBP activity had the lowest levels at neonatal period and then increasing tendency until puberty period and remained steady level until adult period. Regulation of GHBP may be closely related with metabolic control state by insulin, GH, nutritional status, and thyroid hormone..

6.Changes in Macular Retinal Layers and Peripapillary Nerve Fiber Layer Thickness after 577-nm Pattern Scanning Laser in Patients with Diabetic Retinopathy.
Korean Journal of Ophthalmology 2017;31(6):497-507
PURPOSE: The aim of this study was to evaluate the changes in thickness of each macular retinal layer, the peripapillary retinal nerve fiber layer (RNFL), and central macular thickness (CMT) after 577-nm pattern scanning laser (PASCAL) photocoagulation in patients with diabetic retinopathy. METHODS: This retrospective study included 33 eyes with diabetic retinopathy that underwent 577-nm PASCAL photocoagulation. Each retinal layer thickness, peripapillary RNFL thickness, and CMT were measured by spectral-domain optical coherence tomography before 577-nm PASCAL photocoagulation, as well as at 1, 6, and 12 months after 577-nm PASCAL photocoagulation. Computerized intraretinal segmentation of optical coherence tomography was performed to identify the thickness of each retinal layer. RESULTS: The average thickness of the RNFL, ganglion cell layer, inner plexiform layer, inner nuclear layer, inner retinal layer, and CMT at each follow-up increased significantly from baseline (p < 0.001), whereas that of the retinal pigment epithelium at each follow-up decreased significantly from baseline (p < 0.001). The average thickness of the peripapillary RNFL increased significantly at one month (p < 0.001). This thickness subsequently recovered to 7.48 µm, and there were no significant changes at six or 12 months compared to baseline (p > 0.05). CONCLUSIONS: Each macular retinal layer and CMT had a tendency to increase for one year after 577-nm PASCAL photocoagulation, whereas the average thickness of retinal pigment epithelium decreased at one-year follow-up compared to the baseline. Although an increase in peripapillary RNFL thickness was observed one month after 577-nm PASCAL photocoagulation, there were no significant changes at the one-year follow-up compared to the baseline.

The Y-chromosome, as with other chromosomes in the cell, is subject to mutations. However, unlike autosomal genes, the Y chromosome does not undergo recombination, and therefore individuals from different geographical regions may have differing distribution patterns with respect to Y-chromosome mutations. More detailed knowledge and information regarding Y-chromosome mutations might therefore provide insights into phylogenetic history and personal identification. Here, we describe a case study involving genotype-phenotype discrepancy in an Indian male individual. We found that the mistyping in sex determination was caused by a deletion in the amelogenin Y (AMEL Y) gene. Furthermore, on examining the short tandem repeat (Y-STR) loci using the PowerPlex(R) Y23 System, we found four more deleted loci on Yp11.2 (DYS576, DYS481, DYS570, and DYS458) in this sample. We performed deletion mapping for this sample, and we propose that the microdeletion on the Yp11.2 locus occurred approximately in the 6.44 Mb to 9.75 Mb region. Previous studies have reported that the AMEL Y deletion is a common mutation in the Indian population. Taking into account regional differences, we also analyzed several area-specific Y-chromosome mutations.

The incidence of severe hepatitis A virus (HAV) infection has been increasing. However, clinicopathologic features of severe HAV infection that lead to liver transplantation (LT) have not been reported in Korea. We retrieved 16 LT cases with HAV infection during the last 3 years at Asan Medical Center, Seoul, Korea. Fifteen cases progressed to hepatic encephalopathy. Thirteen cases survived with or without complications, and three patients died of sepsis. The explanted liver showed massive or zonal necrosis with moderate to severe cholestasis. The zonal distribution of necrosis was frequently associated with endothelialitis of portal and/or central veins. Degenerative changes of hepatocytes were various in degree and distribution. Viral inclusions were suspected in two cases. Although HAV infection is usually confirmed by serological tests, significant venulitis of central and/or portal veins and viral inclusions, which are rarely observed, can suggest an HAV infection as a cause of massive hepatic necrosis of unknown mechanism.

9.Placement of feeding tubes using fluoroscopy guidance and over-the-wire technique: A technical review.
Gastrointestinal Intervention 2017;6(2):135-139
Nutritional support is essential for improving the outcome in critically ill patients. Enteral nutrition possesses advantages over total parenteral nutrition in that it maintains the physiologic barrier function of the gastrointestinal mucosa. Short-term enteral nutrition can be achieved through transnasal feeding tubes. Traditionally, feeding tubes have been placed at bedside in a blind fashion. However, blind tube placement is unreliable as it may result in improper positioning of the tubes. Numerous complications arising from misplacement have been reported in the literature. A number of modalities may be used in order to improve the accuracy and safety of transnasal feeding tube placement. Fluoroscopy is widely accepted for this purpose. Together with the use of water-soluble contrast media and over-the-wire technique, fluoroscopy-guided placement of nasogastric or nasojejunal feeding tubes offers a higher rate of technical success while decreasing procedure time as well as the incidence of procedure-related complications.

Complications after a median sternotomy incision, which is used currently in most open heart surgery, are serious, although it is infrequent. Reconstruction of the sternal defect resulting from dehiscence of median sternotomy is still big challenge to the most plastic surgeons. Since vascularized greater omentum was transposed to eliminate mediastinal wound problems, many vascularized regional muscle flaps became mainstay in reconstruction of median sternotomy wound. We treated 13 patients with median sternotomy dehiscence between October of 1993 and March of 1998. In two patients, the wound problems were so confined to superficial tissue that debrided and closed primarily. Eleven patients with deep wound infection were managed with vigorous debridement of all necrotic tissues and resultant defects were covered with regional muscle flaps: rectus myocutaneous flap(3) and bilateral pectoralis advancement flap(8). We used the pectoralis major advancement flaps without counter incision at humeral insertion site and the dissections were limited only medial to the anterior axillary line to preserve the axillary fold. In five patients with larger defects, we elevated muscle and cutaneous flaps separately to make these flaps more mobile. Large portion of two rectus abdominis flaps could not survive, whereas pectoralis advancement flaps had mo special wound problems. Only one patient developed fistula due to remained wire, regardless to flap surgery.
