Medication-related osteonecrosis of the jaw (MRONJ) is a severe complication associated with antiresorptive or anticancer agents.Surgical intervention is generally recommended for advanced stages, but some patients may be ineligible for surgery due to systemic conditions or anatomical limitations. We present two patients who had been treated for osteoporosis with bisphosphonates and were diagnosed with stage 2 MRONJ. Their chief complaints included refractory pain, purulent discharge, and exposed bone following tooth extraction. Despite conservative treatment, the MRONJ worsened, prompting the initiation of teriparatide therapy. After teriparatide administration, the patients experienced symptom improvement, spontaneous sequestrum removal, and significant bone regeneration of vertical osteolysis. Teriparatide, a bone anabolic agent, is typically recommended as adjuvant therapy alongside surgical treatment for MRONJ. This case report illustrates the effectiveness of teriparatide monotherapy in the absence of surgical intervention, particularly for patients who cannot discontinue antiresorptive agents due to low bone mineral density.

Objectives: ：This study aimed to investigate quality of life, severity of depression, suicidality, subjective health and subjective stress of depression with subjective cognitive decline in Korean adults. Methods: ：We used the 7th KNHANES data to enroll 415 participants with a score of 10 or higher on Patient Health Questionnaire-9 (PHQ-9), aged 20-64. Depression was divided into two groups based on the presence/absence of subjective cognitive decline. Demographic and psychological characteristics were compared between two groups. Correlation analysis of subjective cognitive decline, quality of life, depression, suicidal idea was car-ried out. To detect which variables influenced quality of life, a multiple regression analysis was carried out. Results: ：Among the 415 participants, 98 had depression with subjective cognitive decline. We identified sig-nificant differences in age, marital status, education, employment between the two groups. After adjusting for these variables, depression with subjective cognitive decline had lower EuroQol-5D index scores, more severe depressive symptoms without cognition and worse subjective health than depression without cognitive decline. There was a significant correlation between subjective cognitive decline and quality of life (r=-0.236, p<0.001), suicidal idea (r=0.182, p<0.001), depression score without cognition (r=0.108, p=0.028). Through multiple regression analysis, subjective cognitive decline was predictor of reduced quality of life (β=-0.178, p<0.001). Conclusions ：Depression with subjective cognitive decline has poor quality of life and severe depression. Cognitive decline should be considered to improve treatment result in depression.

Erlotinib is accepted as a standard second-line chemotherapeutic agent in patients with non-small cell lung cancer who are refractory or resistant to first-line platinum-based chemotherapy. There has been no previous report of bowel perforation with or without gastrointestinal metastases related to erlotinib in patients with non-small cell lung cancer. The exact mechanism of bowel perforation in patients who received erlotinib remains unclear. In this report, we report the first case of enterocutaneous fistula in a female patient with metastatic non-small cell lung cancer 9 months, following medication with erlotinib as second-line chemotherapy.

Hepatic hemangioma is the most common benign tumor of the liver. Most such hemangiomas are small, asymptomatic, and have an excellent prognosis. Giant hepatic hemangioma has been reported in the literature, but the exophytic and pedunculated forms of hepatic hemangioma are rare. A 56-year-old woman was referred to our hospital under the suspicion of having a gastric submucosal tumor. Abdominal computer tomography (CT) scans showed a pedunculated mass from the left lateral segment of the liver into the gastric fundus, exhibiting the atypical CT findings of hepatic hemangioma. We therefore decided to perform laparoscopic resection based on the symptoms, relatively large diameter, inability to exclude malignancy, and risk of rupture of the exophytic lesion. The pathology indicated it to be a cavernous hemangioma of the liver. Herein we report a case of pedunculated hepatic hemangioma mimicking a submucosal tumor of the stomach due to extrinsic compression of the gastric fundus.

PURPOSE: Radioimmunoassay (RIA) was usually performed by the batch assay. To improve the efficiency of RIA without increase of the cost and time, random assay could be a choice. We investigated the possibility of the random assay using automatic dispenser by assessing the agreement between batch assay and random assay. MATERIALS AND METHODS: The experiments were performed with four items; Triiodothyronine (T3), free thyroxine (fT4), Prostate specific antigen (PSA), Carcinoembryonic antigen (CEA). In each item, the sera of twenty patients, the standard, and the control samples were used. The measurements were done 4 times with 3 hour time intervals by random assay and batch assay. The coefficient of variation (CV) of the standard samples and patients' data in T3, fT4, PSA, and CEA were assessed. ICC (Intraclass correlation coefficient) and coefficient of correlation were measured to assessing the agreement between two methods. RESULTS: The CVs (%) of T3, fT4, PSA, and CEA measured by batch assay were 3.2+/-1.7%, 3.9+/-2.1%, 7.1+/-6.2%, 11.2+/-7.2%. The CVs by random assay were 2.1+/-1.7%, 4.8+/-3.1%, 3.6+/-4.8%, and 7.4+/-6.2%. The ICC between the batch assay and random assay were 0.9968 (T3), 0.9973 (fT4), 0.9996 (PSA), and 0.9901 (CEA). The coefficient of correlation between the batch assay and random assay were 0.9924(T3), 0.9974 (fT4), 0.9994 (PSA), and 0.9989 (CEA) (p<0.05). CONCLUSION: The results of random assay showed strong agreement with the batch assay in a day. These results suggest that random assay using automatic dispenser could be used in radioimmunoassay.

The incidence and etiology of parasite-associated gastroenteritis during 2004-2006 in Gyeonggi-do (province), South Korea was determined by means of antigen detection ELISA on 6,071 stool specimens collected from 6 general hospitals. At least 1 parasitic agent was detected in 3.4% (208/6,071) of the stool samples. Among these, Giardia lamblia was the most numerous (152 cases; 2.5%), followed by Entamoeba histolytica (25 cases; 0.4%), Cryptosporidium parvum (23 cases; 0.4%), and mixed infections (8 cases; 0.1%). Patients aged 1-5 years had the largest proportion (69.2%; 144/208) of parasite-positive stool specimens. Parasite-mediated gastroenteritis was most common from June to September. The detection rate gradually increased from 2004 to 2006. This study shows that parasite-mediated gastroenteritis may be significant among children in Korea and that parasite infection surveillance should be constantly performed.

Schilder's disease or myelinoclastic diffuse sclerosis (MDS) is a rare variant of multiple sclerosis. We report a 66-year-old woman with progressive motor weakness and diffuse white matter degeneration on MRI, which satisfies the Poser's restrictive criteria of MDS. As previously reported cases of probable Schilder's disease did not meet the criteria correctly, we consider our patient is the first pathology-proven case of MDS in Korea.

BACKGROUND: The study of pneumonia among young men living in a group is rare. prospective study was conducted to determine the etiology, and compare the effects of macrolide and second-generation cephalosporin on the treatment of pneumonia among combat policemen. PATIENTS AND METHODS: From January 2003 to April 2004, Fifty-two patients with pneumonia were treated with either azithromycin(n=25) or cefuroxime(n=27). In order to determine the cause of the pneumonia, culture studies and serologic tests for antibodies to Mycoplasma pneumoniae and Chlamydia pneumoniae were carried out. During the two weeks of medication, the Chest X-rays, blood tests and culture studies(if necessary) were followed weekly. A serologic study was followed at the end of the second week. RESULTS: The main pathogens for pneumonia among combat policemen were Mycoplasma pneumoniae(50.0%), Chlamydia pneumoniae(10.8%), and Streptococcus pneumoniae(3.8%). The treatment was successful in most cases(51/52 cases, 98.1%). The effects of azithromycin and cefuroxime were similar (96.0% vs 100%, p>5). In one patient who had taken azithromycin, the clinical and radiological findings did not improved until intravenous second generation ce?phalosporin had been infused. CONCLUSION: Atypical pathogens were the main causes of the pneumonia in the combat policemen, and the effects of macrolide and second generation cephalosporin for pneumonia were similar. However, further studies will be needed to determine if single therapy with macrolide is possible.

Chronic osteomyelitis is often considered difficult to treat and may lead to refratory condition in oral and maxillofacial region. Clinical features of chronic osteomyelitis includes pain, swelling, pus discharge, and radiographic change. There are many kinds of treatment of chronic osteomyelitis. One of the most important factors in treating osteomyelitis are removal of infectious foci and administration of massive antibiotics. Recently we reviewed 29 patients with chronic osteomyelitis who visited in our department and treated successfully with our treatment protocols, consisting of surgical intervention and intravenous antibiotics for 2 weeks, and followed by oral antibiotics for 6 weeks. It is concluded that combination of surgical intervention and antibiotic therapy are sufficient to treat the chronic osteomyelitis in oral and maxillofacial region.
