OBJECTIVES: The aim of this study was to retrospectively evaluate the clinical survival rate of Astra Tech implants in the maxillary molar region performed with sinus lift and bone graft. MATERIALS AND METHODS: Ninety-nine Astra Tech implants (Osseospeed) placed in the maxillary molar region using sinus lift from September 2009 to February 2012 were selected with a minimum follow-up period of 1 year. The height of alveolar bone, sinus approach technique, bone material and implant survival rate were evaluated. RESULTS: Of the 99 implants, the survival rate was 90.9%; 8 implants failed within 1 year after implant placement, and 1 implant failed 1 year after implant loading. All failed implants were placed with sinus lift simultaneously. The average height of alveolar bone before implant placement was 6.9 mm, while the height of alveolar bone of failed implants was 2.1 mm, on average. CONCLUSION: Astra Tech implants placed in the maxillary molar region had generally good survival rates, but the relationship between reduced pre-implant alveolar bone height and implant failure requires further attention.

Preadipocyte factor-1 (Pref-1) is expressed in the neuroendocrine organs such as the pituitary gland, the adrenal gland, the pancreas, the testis, etc. Vitamin D3 up-regulated protein 1(VDUP1) gene is known to be a novel member of early response genes as an oxidative stress mediator. The aim of the present study was to investigate whether Pref-1 and VDUP1 is involved in stress response in the adrenal gland following chronic immobilization stress. In situ hybridization for Pref-1 and VDUP1 genes (Pref-1 and VDUP1) was performed in the rat adrenal glands following immobilization stress, 2 hr once daily for 7 days. In situ hybridization analysis revealed that Pref-1 expression was up-regulated in rat adrenal medulla following chronic immobilization stress. However, Pref-1 was down-regulated in the zona glomerulosa of the adrenal cortex following chronic immobilization stress. VDUP1 expression was up-regulated in the zona glomerulosa and the adrenal medulla following chronic immobilization stress. These results show that Pref-1 and VDUP1 may be novel genes responding to chronic immobilization stress in adrenal gland.

PURPOSE: To investigate the change in mitogen-activated protein kinase pathways in the brain tissue after therapeutic hypothermia in the swine cardiac arrest model. METHODS: After the return of spontaneous circulation by cardiopulmonary resuscitation, following a 6 min of no-flow time induced by ventricular fibrillation, pigs (n=24) were randomly assigned to one of four groups (sham, normothermia, 24 hr of therapeutic hypothermia, 48 hr of therapeutic hypothermia). After 24 or 48 hr of therapeutic hypothermia (core temperature 32-34℃), the pigs were then rewarmed to 36℃ for a period of 8 hr. At 60 hr upon the return of spontaneous circulation, the pigs were sacrificed and brain tissues were harvested. RESULTS: We measured the tissue levels of p38, JNK, and ERK pathway expressions from the hippocampus of the swine brain in all four groups. The phosphorylated p38-to-p38 ratio and phosphorylated JNK-to-JNK ratio were significantly increased in all of the intervention groups compared with the sham group. The phosphorylated ERK-to-ERK ratio was increased only in the therapeutic hypothermia groups (p-value=0.026 in the 24 hr of therapeutic hypothermia group and p-value=0.002 in the 48 hr of therapeutic hypothermia group, compared with the sham group). CONCLUSION: The p38 and JNK pathways were also activated during therapeutic hypothermia and normothermia. However, the ERK pathway was activated only in therapeutic hypothermia. Therapeutic hypothermia activated the ERK pathway in ischemia-reperfusion injury of the brain tissue after cardiac arrest, which seemed to be dependent on the duration of therapeutic hypothermia.

PURPOSE: It is well known that multiple sclerosis(MS) is a demyelinating disease of the central nervous system that mostly starts in the second to third decades. In the present study, we reviewed our own observations of the clinical and paraclinical features of the MS patients whose symptoms started before 16 years of age. METHODS: The study concerns the patients admitted to the pediatric department of Asan Medical Center for a period of 5 years(from January 1996 to December 2002). We retrospectively reviewed 13 patients who were diagnosed as early onset multiple sclerosis by Rose criteria on the basis of clinical symptoms and brain MRI findings. RESULTS: Of these 13 patients, 5 patients(38.5%) fulfilled the criteria of clinically definite MS and 7 patients(53.8%) fulfilled the criteria of clinically probable MS. The average age at onset was 10.3 years old. In six patients, the disease onset was polysymptomatic. Diplopia was the most common initial manifestation and occurred in 8 patients (61.5%). Others presented with urinary incontinence, ataxia, seizures and so on. All the patients had typical T2-hyperintensive lesions on brain MRI and brainstem lesions were found in 5 patients(38.5%). All the patients responsed to intravenous methylprednisolone very well. No long-term neurologic sequelae were observed. CONCLUSION: Although childhood onset MS is rarely seen and may begin with unusual features, it dose not significantly differ from that typically seen in adults in terms of major clinical manifestations and clinical course of the disease. It is also suggested that MRI is a sensitive and effective tool for the diagnosis of MS.

OBJECTIVE: Lin28 has been known to control the proliferation and pluripotency of embryonic stem cells. The purpose of this study was to determine the downstream effectors of Lin28 in mouse embryonic stem cells (mESCs) by RNA interference and microarray analysis. METHODS: The control siRNA and Lin28 siRNA (Dharmacon) were transfected into mESCs. Total RNA was prepared from each type of transfected mESC and subjected to reverse transcription-polymerase chain reaction (RT-PCR) analysis to confirm the downregulation of Lin28. The RNAs were labeled and hybridized with an Affymetrix Gene-Chip Mouse Genome 430 2.0 array. The data analysis was accomplished by GenPlex 3.0 software. The expression levels of selected genes were confirmed by quantitative real-time RT-PCR. RESULTS: According to the statistical analysis of the cDNA microarray, a total of 500 genes were altered in Lin28-downregulated mESCs (up-regulated, 384; down-regulated, 116). After differentially expressed gene filtering, 31 genes were selected as candidate genes regulated by Lin28 downregulation. Among them, neuropeptide Y5 receptor and oocyte-specific homeobox 5 genes were significantly upregulated in Lin28-downregulated mESCs. We also showed that the families of neuropeptide Y receptor (Npyr) and oocyte-specific homeobox (Obox) genes were upregulated by downregulation of Lin28. CONCLUSION: Based on the results of this study, we suggest that Lin28 controls the characteristics of mESCs through the regulation of effectors such as the Npyr and Obox families.

The diffuse sclerosing variant of papillary thyroid carcinoma (DSPTC) is uncommon. Herein, we report a rare case of DSPTC in a 9-year-old girl who initially presented with a painless diffuse goiter. Thyroid peroxidase antibody testing yielded positive results, and the initial clinical diagnosis was Hashimoto's thyroiditis. However, thyroid ultrasonography revealed characteristic findings of DSPTC, which was confirmed through the postoperative histopathological diagnosis. Although thyroid cancers are rare in the pediatric population, DSPTC should be included in the differential diagnosis of goiter in these patients. Moreover, ultrasonography may prevent a diagnostic delay and facilitate the detection of a concomitant malignancy.

BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) nasal colonization has been known as a predictor of intensive care unit (ICU)-acquired MRSA infections. We performed this study to survey the nasal colonization of MRSA among the patients admitted to an ICU and analyze risk factors associated with the colonization. METHODS: A retrospective 1:1 matched case-control study was conducted with patients admitted to the ICU from March to December 2010 at Samsung Changwon Hospital. RESULTS: A total of 602 patients among 846 patients admitted to the ICU during the study period were evaluated. The prevalence of nasal MRSA colonization was 67 (11.1%) of 602. Other factors, including underlying renal disease (odds ratio [OR]=12.37, 95% confidence interval [CI] 3.60-42.54; P<0.001), MRSA infection within the previous 3 months (OR=7.43, 95% CI 1.31-42.05; P=0.023), nursing home resident within the previous 1 month (OR=6.25, 95% CI 1.82-21.53; P=0.004), surgical procedure within the previous 1 month (OR=5.93, 95% CI 1.86-18.85; P=0.003), and current use of nasogastric tube (OR=4.98, 95% CI 1.84-13.45; P=0.002) were independently associated with nasal MRSA colonization in patients admitted to ICU. CONCLUSION: A significant number of patients admitted to the ICU in a secondary hospital were colonized with MRSA. The present study showed the possible impact of the presence of a nasogastric tube on the nasal colonization by MRSA. More effective infection control procedures must be developed for patients with nasogastric tube use.
