Authors reviewed and analyzed 108 cases of secundum ASD(1–15 years old), which had been diagnosed bycineangiography in Seoul Natinal University Children's Hospital from 1979 to 1985. 1) The incidence of theasociation of MVP with secundum ASD was 48%(Male 43%, Female 52%). 2) The incidnece of this association incresedwith age(1–5 years old: 39%, 6–10 : 50%, 11–15: 59%). 3) The incidence of concurrent mitral regurgitation in MVPassociated with ASD was 48%. No special correlation was not found between the degree or incidence of MVP and thatof MR. 4) The incedence of the association of MVP with ASD increased with the increaseing amount of leftventricular geomatry attendant on left to right shunt (QS/QS < 2:33%, 2<=QP/QS < 4:52%, QP/QS >= 4: 100%). Thissuggested that abnormal left ventricular geometry attendant on left to ring shunt would contribute much to theassociation of MVP with secundum ASD.

The diagnostic value of the DNA polymerase chain reaction for the detection of M. tuberculosis in tuberculous meningitis uas established by using cerebrospinal fluids obtained from 7 bacteriologically confirmed patients (Group IA), 17 clinically diagnosed patients (Group IB), 21 patients with other bacterial or viral meningitis (Group IIA) and two norrnal persons (Group IIB) The PCR was perforrned with P1 and P2 primer set which directed against the 123bp segment of IS5110. A repetitive sequence of M. tuberculosis chromosome. The sensitivity and specificity of the PCR for the detection of M. tuberculosis was evaluated by using DNAs purified from cultured M tuberculosis and M intracellulare . The detection limit by the PCR amplication with Pl and P2 primer was lfg of DNA for M. tuberculosis and lpg for M. intracellulare indicating that the PCR was very sensitive for M. tubererculosis DNA detection; although weakly cross-reactive with DNA of M. tuberculosis. Of the 7 cerebrospinnal fluids from bacterologically proven tuberculous meningitis patients (Group IA), 7 samples were all positive by PCR (10Q%). 15 sarnples of 17 the AFB smear-negative and culture-negative samples from tuberculous meningitis patients (Group IB) were positive by PCR (88.2%) and 2 of 2l sanples from other meningitis patients (Group IIA) showed positive reaction (9.5%). There were no sarnples whick showed positive reaction by PCR among 2 sarnples from normal persons (Group IIB). This results indicated that the PCR using P1 and P2 primer set was useful for the early diagosis of tuberculous meningitis.

PURPOSE: Huge benign tumors in the hands sometimes show aggressive nature clinically. We report the clinical features of patients with a large benign recurrent tumors in the hands. METHODS: We retrospectively reviewed 139 benign tumors in hands excised by the authors between January, 2006 and March, 2012. There were 4 cases of huge benign tumors in hands that recurred after total excision. RESULTS: The average initial tumor size was 5.3x3.3 cm and the average recurrent tumor size was 4.4x3.0 cm. The average period of recurrence from initial operation was 11.3 months. The pathologic findings involved one epidermal cyst, two fibromatosis, and one giant cell tumor of tendon sheath. Although radical removal of the tumors were successful, reoperation due to the tumor recurrence was required. CONCLUSION: Regardless of the tumor malignancy, a wide range of tumor resection and radiation therapy may be necessary in order to prevent the recurrence of tumors in the hand. Sufficient follow-up periods to determine recurrence were required.

PURPOSE: Although lipoma is known as one of the most common soft tissue tumors, calcification in lipoma is very rare in its occurrence. This calcified lipoma has been reported by some as a result of regression of lipoma, but its genesis is not clearly known yet with various opinions being discussed regarding its possible metabolic relation to hypercalcemia or hyperphosphatemia to be considered as a regression phase of lipoma. The authors would like to present this unusual case of calcified lipoma. METHODS: A 50-year-old male patient visited our hospital with complaint of an enlarging mass on his right forehead which has been acknowledged for 5 years' period. On physical examination, a mass was observed on his forehead as palpable, non-tender, mobile and firm in its consistency. Ultra sonogram examination revealed a well-demarcated mass (1.92 cm) with central echoic zone at deep layer of forehead. Mass excision and biopsy were performed subsequently. RESULTS: According to the pathological report, the diagnosis confirmed the lipoma consisting of grown-up adipocyte and calcification. Neither growing lipoma nor relapse was observed for postoperative three years' follow-up of the patient. CONCLUSION: Now that the calcified lipoma was successfully removed and cured by a simple mass excision, authors hereby report the case of calcified lipoma on forehead.

We report a 71-year-old male presenting with painful growing mass on his left thumb. The patient had received iliac bone graft on his left thumb 20 years ago, and removed all the grafted bone 8 years ago due to recurrent ulcer. Biopsy revealed multiple eidermal inclusion cysts on the dorsal surface of the bone graft site. Surgeon should be aware of epidermal inclusion cyst occurred at the previous bone graft site of the finger.

PURPOSE: Incomplete syndactyly, due to either congenital or acquired, is uncommon. Many different surgical methods have been descirbed. We introduce the modification of seven flap-plasty for incomplete syndactyly and report functional improvement after correction by modified seven flap-plasty without skin graft. MATERIALS AND METHODS: Twelve patients with an incomplete syndactyly who underwent modified seven flap-plasty were analyzed. Age ranged from one to 40-year-old (average age 21). There were 8 males and 4 females, and the degree of syndactyly was near proximal interphalangeal joint. Two different operative methods were performed. Modification I modified two half-Z flaps in parallelogram shape, and modification II modified V flap of V-M flap in Y-V flap. Functional improvements was measured by maximal abduction distance and maximal abduction angle change. RESULTS: All cases were corrected by using the modified seven flap plasty. Flap tip necrosis was found in two cases of severe burn scar patients, but did not require additional surgery. There was no specific complications. Maximal abduction distance was increased in 6 mm, and maximal abduction angle was increased in 5.8degrees. CONCLUSION: Incomplete syndactyly near proximal interphalangeal joint was corrected by modified seven flap plasty and was able to get a satisfactory result.

There are limited data evaluating the relationship between influenza treatment and hospitalization duration. Our purpose assessed the association between different treatments and hospital stay among Korean pediatric influenza patients. Total 770 children < or = 15 yr-of-age hospitalized with community-acquired laboratory-confirmed influenza at three large urban tertiary care hospitals were identified through a retrospective medical chart review. Demographic, clinical, and cost data were extracted and a multivariable linear regression model was used to assess the associations between influenza treatment types and hospital stay. Overall, there were 81% of the patients hospitalized with laboratory-confirmed influenza who received antibiotic monotherapy whereas only 4% of the patients received oseltamivir monotherapy. The mean treatment-related charges for hospitalizations treated with antibiotics, alone or with oseltamivir, were significantly higher than those treated with oseltamivir-only (P < 0.001). Influenza patients treated with antibiotics-only and antibiotics/oseltamivir combination therapy showed 44.9% and 28.2%, respectively, longer duration of hospitalization compared to those treated with oseltamivir-only. Patients treated with antibiotics, alone or combined with oseltamivir, were associated with longer hospitalization and significantly higher medical charges, compared to patients treated with oseltamivir alone. In Korea, there is a need for more judicious use of antibiotics, appropriate use of influenza rapid testing.

Journal of Preventive Medicine and Public Health 2022;55(6):529-538
Objectives:
This study aimed to identify the current patterns of cancer incidence and estimate the projected cancer incidence and mortality between 2020 and 2035 in Korea.
Methods:
Data on cancer incidence cases were extracted from the Korean Statistical Information Service from 2000 to 2017, and data on cancer-related deaths were extracted from the National Cancer Center from 2000 to 2018. Cancer cases and deaths were classified according to the International Classification of Diseases, 10th edition. For the current patterns of cancer incidence, age-standardized incidence rates (ASIRs) and age-standardized mortality rates were investigated using the 2000 mid-year estimated population aged over 20 years and older. A joinpoint regression model was used to determine the 2020 to 2035 trends in cancer.
Results:
Overall, cancer cases were predicted to increase from 265 299 in 2020 to 474 085 in 2035 (growth rate: 1.8%). The greatest increase in the ASIR was projected for prostate cancer among male (7.84 vs. 189.53 per 100 000 people) and breast cancer among female (34.17 vs. 238.45 per 100 000 people) from 2000 to 2035. Overall cancer deaths were projected to increase from 81 717 in 2020 to 95 845 in 2035 (average annual growth rate: 1.2%). Although most cancer mortality rates were projected to decrease, those of breast, pancreatic, and ovarian cancer among female were projected to increase until 2035.
Conclusions
These up-to-date projections of cancer incidence and mortality in the Korean population may be a significant resource for implementing cancer-related regulations or developing cancer treatments.

Objectives:
We aimed to examine the association between the relative preference for vegetables and meat and cancer incidence, in a population-based retrospective cohort in Korea.
Methods:
We included 10,148,131 participants (5,794,124 men; 4,354,007 women) who underwent national health screening between 2004 and 2005 from the National Health Information Database of the National Health Insurance Service (NHIS-NHID). Participants were asked whether they preferred consuming 1) vegetables more often, 2) both vegetables and meat or 3) meat more often. Participants were followed up to Dec. 31, 2017. All cancer and eighteen common cancer cases were identified through the code from the International Classification of Diseases, 10th revision. We estimated sexspecific relative risks and 95% confidence intervals, adjusting for age, body mass index, alcohol consumption, smoking, physical activity, and income level.
Results:
During an average follow-up of 12.4 years, 714,170 cancer cases were documented. In men, consuming meat more often was associated with lower risk of esophageal, liver, and stomach cancers, but higher risk of lung and kidney cancers. Consuming both vegetables and meat was associated with higher risk of prostate cancer, but with lower risk of esophageal, liver, and stomach cancers in men. In women, consuming meat more often was associated with a higher risk of colorectal cancer and breast, endometrial, and cervical cancers diagnosed before the age of 50. Consuming both vegetables and meat was associated with lower risk of liver cancer in women.
Conclusions
Our study suggests a potential link between vegetable and meat intake and cancer incidence in the Korean population. Further investigation on the association between the intake of specific types of vegetables and meat and cancer risk in Korean prospective cohort studies is needed.
