Immunoglobulin deficiency with increased IgM, as defined by World Health Organization classification of primary immunodeficiency, is characterized by normal or increased concentrations of serum IgM and, in some cases, IgD, but decreased or absent IgG, IgA, and IgE. Patients with these disorders have a high incidence of recurrent pyogenic infections, including otitis media, pneumonia, and septisemia. We recently experienced a case of immunoglobulin deficiency with increased IgM in a 25-year old man. He had been suffered from recurrent pyogenic infections-pneumonia, otitis media-since about 6 months of his age. He was admitted due to pneumonia, and Haemophilus influenza was isolated from the sputum culture. Also chest X-ray showed bronchiectasis. His serum immunoglobulin levels revealed increased concentration of IgM and decreased IgG and IgA. He was successfully treated with antibiotics, and now he is being followed-up. So we present this case with the review of literature.

As a technique mainly hiring in forensic investigation field to identify the descents, craniofacial reconstruction (CFR) is also used in archaeology to create the faces from ancient or medieval human remains, when there is little information about his/her appearance. Eung-Cheok Ko (1531–1605) was a writer and scholar in the mid Joseon period. In January of 2019, His mummified body was found at Gumi, Kyeonsangbuk-do, Korea. The remains were anthropologically examined, and archaeological CFR was also requested for this case. This report reveals the case’s facial reconstruction process and his portrait that is drawn based on the 3-dimensional CFR result.

PURPOSE: The aim of this study was to confirm the efficacy and safety of regorafenib for advanced gastrointestinal stromal tumors (GISTs) reported in the GRID phase III trial in Korean patients. MATERIALS AND METHODS: Fifty-seven Korean patientswith advanced GISTwho experienced both imatinib and sunitinib failure were enrolled in the management access program between December 2012 and November 2013 and treated with regorafenib (160 mg orally once daily in a 3 weeks on/1 week off). RESULTS: None of the patients achieved a complete or partial response while 25 patients (44%) showed stable disease for ≥ 12 weeks. With a median follow-up of 12.7 months (range, 0.2 to 27.6 months), the median progression-free survival and overall survival were 4.5 months (95% confidence interval [CI], 3.8 to 5.3) and 12.9 months (95% CI, 8.1 to 17.7), respectively. Interestingly, 15 patients (26%) experienced an exacerbation of their cancer-related symptoms (abdominal pain in eight and abdominal distension in five) during the rest period for regorafenib, but all were ameliorated upon the resumption of regorafenib. The most common grade 3 or 4 adverse event was a hand-foot skin reaction (25%). The regorafenib dose was reduced in 44 patients (77%) due to toxicity, which manifested mainly as a hand-foot skin reaction (n=31). CONCLUSION: This study confirmed the efficacy and safety of regorafenib for advanced GIST after imatinib and sunitinib failure in Korean patients. Considering the exacerbation of the cancer-related symptoms observed during the rest periods, further exploration of the continuous dosing schedule of regorafenib is warranted in future clinical trials.

BACKGROUND: Since video-assisted thoracoscopic surgery (VATS) was introduced as a new treatment modality for empyema thoracis, numerous reports have suggested that VATS is a more effective treatment method than the traditional methods that mainly use antibiotics and drainage apparatus. However, no confirmative evidence of the superiority of VATS over the traditional method has been provided yet. METHODS: We attempted to evaluate the efficacy of VATS for the treatment of empyema thoracis by reviewing past medical records and simple chest films. First, we divided the patients into two groups based on the treatment method: group A of 15 patients who were treated with the traditional method between January 2001 and December 2003, and group B of 9 patients who were treated with VATS between December 2003 and August 2006. The final outcomes used in this study were the number of days of hospital stay, chest tube duration, leukocytosis duration, febrile duration, and intravenous antibiotics usage duration. In addition, radiological improvements were compared. RESULTS: The mean age(+/-standard deviation) of 11 men and 4 women in group A was 58.2+/-15.7 years, and of 9 men and 2 women in group B was 51.6+/-9.5 years. Group B had a significantly shorter hospital stay (16.6+/-7.4 vs. 33.7+/-22.6 days; p=0.014), shorter chest tube duration (10.5+/-5.7 vs. 19.5+/-14.4 days; p=0.039), shorter leukocytosis duration (6.7+/-6.5 vs. 18.8+/-13.2 days; p=0.008), shorter febrile duration (0.8+/-1.8 vs. 9.4+/-9.2 days; p=0.004), and shorter duration of intravenous antibiotics usage (14.9+/-6.4 vs. 25.4+/-13.9 days; p=0.018). However, radiological improvements did not show any statistical differences. CONCLUSION: Early application of VATS for empyema thoracis treatment reduced hospital stay, thoracostomy tube duration, leukocytosis duration, febrile duration, and antibiotics usage duration in comparison with the traditional methods. The early performing of VATS might be an effective treatment modality for empyema thoracis.

PURPOSE: To evaluate clinical predictors of cervical abscess in adult patients who present a sore throat. METHODS: We prospectively studied adult patients (18 years of age or older) who presented with a sore throat at one of three hospitals (Chungnam national university hospital, Chungbuk national university hospital, and Konyang university hospital) from June 2010 to June 2011. The enrolled patients received a neck computed tomography scan, and their clinical manifestations were investigated. We evaluated several clinical variables in order to predict the existence of cervical abscess by use of multiple logistic regression analysis, and assessed the ability of the results of these variables to accurately diagnose cervical abscess using a receiver operating characteristic curve. RESULTS: A total of 109 patients were enrolled in this study. We identified two clinical variables (swelling and voice change) useful in predicting the existence of cervical abscess, and the AUC acquired by adding the scores of the two clinical factors was 0.89 (p<0.01). The sensitivity and specificity of these clinical factors to predict cervical abscess were 0.96 and 0.69 when the cut off value was determined to be 2. CONCLUSION: Two clinical factors (swelling and voice change) were useful in predicting the appearance of cervical abscesses. Consideration should be made for the need for incision and drainage of a cervical abscess if a patient presents swelling, or swelling and voice change.

Burkitt's lymphoma is a distinct clinical entity classified as an undifferentiated lymphoma of B-lymphocytic origin. Burkitt's lymphoma cell leukemia occurs when Burkitt's lymphoma cells represent more than 20% of marrow cells and exceed about 5000/ul in blood. We report a case of Burkitt's lymphoma cell leukemia in primary gastric lymphoma in 55-year-old man with 5kg of weight loss for 2 months and epigastric pain for 3 days. Primary gastric lymphoma was diagnosed by biopsies with gastrofiberoscopy and upper abdominal CT scan in this patient. During admission, peripheral blood smear revealed sudden increase in abnormal blasts with multiple vacuoles. Burkitt's lymphoma cell leukemia was diagnosed by peripheral blood smear, bone marrow aspiration and biopsy, immunophenotyping and cytogenetic analysis in this patient. For its great rarity, we report this case with review of literature.

Recent changes in healthcare systems have changed the epidemiologic paradigms in many infectious fields including bloodstream infection (BSI). We compared clinical characteristics of community-acquired (CA), hospital-acquired (HA), and healthcare-associated (HCA) BSI. We performed a prospective nationwide multicenter surveillance study from 9 university hospitals in Korea. Total 1,605 blood isolates were collected from 2006 to 2007, and 1,144 isolates were considered true pathogens. HA-BSI accounted for 48.8%, CA-BSI for 33.2%, and HCA-BSI for 18.0%. HA-BSI and HCA-BSI were more likely to have severe comorbidities. Escherichia coli was the most common isolate in CA-BSI (47.1%) and HCA-BSI (27.2%). In contrast, Staphylococcus aureus (15.2%), coagulase-negative Staphylococcus (15.1%) were the common isolates in HA-BSI. The rate of appropriate empiric antimicrobial therapy was the highest in CA-BSI (89.0%) followed by HCA-BSI (76.4%), and HA-BSI (75.0%). The 30-day mortality rate was the highest in HA-BSI (23.0%) followed by HCA-BSI (18.4%), and CA-BSI (10.2%). High Pitt score and inappropriate empirical antibiotic therapy were the independent risk factors for mortality by multivariate analysis. In conclusion, the present data suggest that clinical features, outcome, and microbiologic features of causative pathogens vary by origin of BSI. Especially, HCA-BSI shows unique clinical characteristics, which should be considered a distinct category for more appropriate antibiotic treatment.

Calcitriol therapy is an important treatment for the prevention and control of secondary hyperparathyroidism in continuous ambulatory peritoneal dialysis (CAPD) patients. However, this often has been limited by the associated hypercalcemia and hyperphosphatemia due to increase in intestinal calcium and phosphorus absorption. Many studies reported that these limitations could be avoided by changing routes, frequency and dose of calcitriol treatment. But, there are still controversy about each methods and the results on the PTH response to conventional calcitriol treatment in CAPD patients. This study was performed to evaluate the factors affecting the response to oral calcitriol in CAPD patients. A retrospective study was done in 92 CAPD patients with secondary hyperparathyroidism(intact PTH level >200pg/ml) on oral calcitriol treatment. After baseline study of serum calcium, phosphorus, alkaline phosphatase, BUN, creatinine and intact PTH, calcitriol therapy was begun via oral rou- te, daily. Serum calcium, phosphorus, alkaline phosphatase, BUN, creatinine, intact FI'H and other bio- chemical markers were checked at 3 month, 6 month after treatment. Parathyroid gland ultrasonography was performed to detect parathyroid hypertrophy and nodule and to measure the diameter of parathymid gland. All the patients were divided into two groups according to percent reduetion of i-PTH(initial PTH PTH after 3, 6 months)X100/initial PTH(%),deltaPTH during oral calcitriol therapy for 3 and 6 months(group I ; delta PTH >30%, group II ; delta PTH <30%). RESULT: 1) All 92 patients(mean age 46.5 11.3yr, M: F 45: 47, mean CAPD duration 51.3 39.4 months) were administered oral calcitriol, daily. Mean calcitriol dose during 3 month was 0.43 0.22Mg and during 6month 0.43 0.24Mg. 2) After 3-month treament, there were significant differences in initial i-PTH, the diameter of parathyroid gland, initial phosphorus, intial total alkaline phosphatase and duration of CAPD between group I and II(406.7+/-196.5 vs. 871.0+/-478Apglml, 6.2+/-2.6 vs. 13.1+/-5.2mm, 5.0+/-1.3 vs. 5.7+/-1.3mg/dl, 93.7+/-4L1 vs. 171.9+/-137.6IU/L, 40.1+/-34.9 vs. 73.5+/-37.8months, p< 0.05, respectively). 4) After 6-month treament, there were significant differences in initial i-PTH, the diameter of parathyroid gland, intial total alkaline phosphatase and duration of CAPD between group I and II(474.1+/-266.6 vs. 889.7+/-485.4pg/ml, 6.4+/-2.7 vs. 14.5+/-5.1mm, 107.9+/-80.1 vs. 180.7+/-121.5IU/L, 40.5+/- 32.9 vs. 81.8+/-35.3months, p<0.05, respectively). 5) The significant negative correlation was shown between deltaPTH and the duration of peritoneal dialysis, the diameter of parathyroid gland, initial PTH level and PTH response during 3-month and 6-month oral calcitriol treatment. The response to oral calcitriol was poor when i-PTH level more than 500pg/ml(kappa 0.429, p value <0.01), the diameter of parathyroid gland more than 10.0mm(kappa 0.641, p value<0.01), the duration of CAPD more than 55months(kappa 0.524, p value< 0.01). These data suggested that initial i-PTH level, the diameter of parathyroid gland size and the duration of CAPD were independent risk factors of the poor response to oral calcitriol therapy in CAPD patients with secondary hyperparathyroidism.

BACKGROUND/AIMS: p53 is known to play a central role in sensing and signaling for the growth arrest and apoptosis in cells with DNA damage. Mutation of p53 is a frequent event in esophageal squamous cell carcinoma (ESCC). p16 protein binds to cyclin dependent kinase 4 (CDK4) inhibiting the ability of CDK4 to interact with cyclin D1, and stimulates the passage through the G1 phase of cell cycle. We observed the expression patterns and frequencies of p53, p16, and cyclin D1 in esophageal dysplasia and in esophageal squamous cell carcinomas. METHODS: In 15 patients of ESCC, 5 patients of esophageal dysplasia and 5 volunteers with normal esophagus, tissue specimens were taken from esophageal lesions during the operation or endoscopic examination. We used specific monoclonal antibodies for p53 protein, p16INK4 protein and cyclin D1. Immunoreactivity was scored. RESULTS: Mean age of all groups was 66 years old (range 47-93) and men to women ratio was 19:1. p53 mutation was observed in 87% (13/15) of ESCC, in 80% (4/5) of esophageal dysplasia, in 0% (0/5) of normal mucosa (p=0.001). p16 expression was seen in 40% (2/5) of esophageal dysplasia, 27% (4/15) of ESCC and 100% (5/5) of normal mucosa (p=0.016). Cyclin D1 expression was not significantly different among 20% (1/5) of esophageal dysplasia, 53% (8/15) of ESCC and 20% (1/5) of normal mucosa. Either the expression of p53 mutation or the loss of p16 occurred in 80% (4/5) of esophageal dysplasia and in 93% (14/15) of ESCC. CONCLUSIONS: The expression of p53 mutation and the loss of p16 might play a central role in the pathogenesis of esophageal squamous cell carcinoma (ESCC), and contribute to the development of precancerous lesion such as dysplasia. In addition, there is a possibility that the mutations of p53 and p16 silencing would be the early events in ESCC development.
