BACKGROUND: In recent years, the incidence of obesity increased in Koreans. The main cause suggested is the diet style of Korean changed to that of Western. It has been proved that obesity is a risk factor or an aggravating factor of hypertension and diabetes mellitus, cardiovascular disease, etc. Primary physician has been interested in the correlation of blood pressure with relative body weight and aging. The purpose of this study was to focus on the influence of age and relative body weight on blood pressure. METHODS: Subjects were collected from 2,068 adults who had received Adult Health Examination. That subjects were divided according to age, relative body weight and then the relation of blood pressure with age according to relative body weight and relation with relative body weight according to age were investigated. RESULTS: Systolic blood pressure increased significantly according to age in all male and female three weight groups and then increased significantly according to relative body weight in all male and female three age groups except male seventh decade group. Diastolic blood pressure increased significantly according to age in all male and female three weight groups except male obesity group and then increased significantly according to the relative body weight in all male and female three age groups except male and female seventh decade groups. Systolic blood pressure has higher correlation with age than relative body weight and diastolic blood pressure has higher correlation with relative body weight in male. In female, systolic and diastolic blood pressure have higher correlations with age. CONCLUSIONS: It can be suggested that blood pressure increase significantly according to aging process and relative body weight. These two factors have a little different effects to systolic and diastolic blood pressure according to sex. Relative body weight has more effect to diastolic blood pressure than systolic blood pressure in male.

Background: The predictive factors for lateral neck lymph node metastasis (LLNM) in papillary thyroid microcarcinoma (PTMC) remain undetermined. This study investigated the clinicopathological characteristics, transcriptomes, and tumor microenvironment in PTMC according to the LLNM status. We aimed to identify the biomarkers associated with LLNM development. Methods: We retrospectively reviewed the medical records of patients with PTMC from two independent institutions between 2018 and 2022 (n=597 and n=467). We compared clinicopathological features between patients without lymph node metastasis (N0) and those with LLNM (N1b). Additionally, laser capture microdissection and RNA sequencing were performed on primary tumors from both groups, including metastatic lymph nodes from the N1b group (n=30; 20 primary tumors and 10 paired LLNMs). We corroborated the findings using RNA sequencing data from 16 BRAF-like PTMCs from The Cancer Genome Atlas. Transcriptomic analyses were validated by immunohistochemical staining. Results: Clinicopathological characteristics, such as male sex, multifocality, extrathyroidal extension, lymphatic invasion, and central node metastasis showed associations with LLNM in PTMCs. Transcriptomic profiles between the N0 and N1b PTMC groups were similar. However, tumor microenvironment deconvolution from RNA sequencing and immunohistochemistry revealed an increased abundance of tumor-associated macrophages, particularly M2 macrophages, in the N1b group. Conclusion Patients with PTMC who have a male sex, multifocality, extrathyroidal extension, lymphatic invasion, and central node metastasis exhibited an elevated risk for LLNM. Furthermore, infiltration of M2 macrophages in the tumor microenvironment potentially supports tumor progression and LLNM in PTMCs.

Intraductal papillomas are the most common subtype of papillomas, which are benign neoplasms of the breast. An intraductal papilloma is usually found as a solitary mass which originates in the major duct of the breast. Intraductal papilloma cases are frequently presented as nipple discharge and most commonly occur in individuals between the ages of 30 and 55 years. Few reports exist regarding cases of intraductal papillomas in children. We report a case of an intraductal papilloma, with imaging findings, which occurred in the breast of an 11-year old girl and presented as bloody nipple discharge.

BACKGROUND: With the ageing population, number of dementia patients is on the rise, as well as the public interest. The population who would visit memory disorder clinic will also grow. The diagnostic significance of brain MRI in dementia lies in idetifying hippocampal atrophy or ischemic lesions. However, patients visiting memory disorder clinic are mostly old-aged with multiple vascular risk factors, raising the risk of cerebrovascular abnormalities. The authors set out to evaluate the need for cerebrevascular imaging in patients who visited memory disorder clinic. METHODS: The study recruited patients who visited the memory clinic in Seoul medical center between July 2011 and June 2012. Among those, patients who had taken the neuropsychiatric test and had both brain MRI and MRA taken were included for analysis. In brain MRI, severities of white matter hyperintensities and presence of cerebral infarction were assessed. In brain MRA, intra- and extra-cranial arterial stenosis and presence of aneurysm were noted. RESULTS: A total of 173 patients was included, and 64 were men. The mean age was 71+/-9.4 years, and the mean education period was 7+/-5.2 years. In brain MRI, white matter hyperintensities were observed in 113 patients (65.3%), and cerebral infarction was present in 57 patients (32.9%). In brain MRA, 88 (50.9%) patients showed more than one stenotic segment in intracranial vessel or proximal ICA and 6 patients (3.5%) were diagnosed with unruptured aneurysm. CONCLUSIONS: The incidence of white matter hyperintensities or stenosis of cerebral vessels on magnetic resonance imaging is very high. Therefore, brain MRI and MRA should be included in diagnostic work up for dementia in patients who are old aged and have multiple vascular risk factors. It would provide clinicians with valuable information in making treatment decisions and prevention of future cerebrovascular accident.

BACKGROUND: North Korea's economic and public health problems began in the early 1990s as a result of the gradual loss of economic support from its communist allies, combined with an inordinate number of natural disasters. The decline in public health has increased the incidence of tuberculosis in North Koreans and refugees. This study investigated tuberculosis situation in North Korean refugees in order to prepare for the future impact of tuberculosis control in Korea. MATERIAL AND METHODS: From 2001 to 2005, tuberculosis patients among North Korean refugees who were diagnosed before or after arriving in South Korea, based on the official records of OO hospital, were enrolled in this study. The demographic and clinical data of the cases were evaluated retrospectively. RESULTS: A total of 42 TB cases were reviewed during the study period. Of these, 37 (88.1%) cases were pulmonary TB. based on the cases identified among the number of North Korean refugees' arriving each year, the annual incidence of pulmonary TB were 900 per 100,000 in 2004, 700 in 2003, The number of smear-positive patients was 20 (47.6%) and the number of culture-positive patients was 18 (42.9%). Of the M. tuberculosis isolates, 2 cases were found to be susceptible to all anti-TB drugs available, 4 were resistant to isoniazid, and 3 were multi-drug resistant. CONCLUSION: The prevalence of pulmonary TB in North Korean Refugees is high. In addition, North Korean refugees suffer from more severe tuberculosis in bacteriological and radiological aspects.

Object : This study was conducted to evaluate the surgical results of the active treatment of unruptured intracranial aneurysms (UIAs) and to suggest treatment indications. METHODS: Operations were performed on 49 patients with 52 UIAs between 1999 and 2005. Medical records and radiologic studies of the patients with UIAs were retrospectively reviewed. The clinical outcomes were evaluated in each patient by the modified Glasgow Outcome Scale (m-GOS) one month after operation. RESULTS: UIAs had a high frequency of a middle cerebral artery (MCA) and an internal carotid artery (ICA) aneurysm. Forty-four UIAs (84.6%) ranged between 5 mm to 15 mm in diameter. Fortysix UIAs were treated by clipping, 2 by wrapping, and coil embolization was used in 3 UIAs. In one patient, which had only one UIA, one procedure and one operation was performed. There was no surgical mortality. In most patients, surgical complications or neurological deteriorations were not found. In three patients, minor neurological deficits of ptosis (2 patients) and spinal subdural hematoma (1 patient) were newly developed after operation. However the patients completely recovered within 3 months after operation. Finally, the surgical mortality and morbidity rate was 0%. CONCLUSION: If the UIAs are larger than 5 mm in diameter and located in a susceptible area for rupture, surgical treatment should be considered for the UIAs. If operation is performed by an expert neurosurgeon, surgical clipping is one of the best treatment modalities with or without endovascular treatment.

Crohn's disease is a rare inflammatory bowel disease in Korea which requires a differential diagnosis with intestinal tuberculosis. In the early stages of Crohn's diseaae, the combiation of bowel wall edema and spasm produces intermittent obstructive manifestations, so the usual subjective symptoms were appeared long standing diarrhea, low grade fever and abdominal pain and distension. We recently experienced a case of Crohn's colitis with repeated bowel obstruction in female adult who underwent surgical resection.
