PURPOSE: To evaluate the pattern of colonic diverticulosis according to age and sex, and recent trend. MATERIALS AND METHODS: The authors retrospectively reviewed 120 cases of colonic diverticulosis in 1,020 patients who had undergone a double contrast barium enema examination between January 1st, 1993, and December 31st, 1995, and analyzed the frequency, size, multiplicity and anatomical site, according to age and sex. Diverticulum size was classified into one of three groups : less than 5mm, 5-10mm, over 10mm in diameter. RESULTS: The overall incidence of colonic diverticulosis was 120 cases among 1,020 patients(11.8%) with an incidence 5.3 times higher in males than in females. Peak incidence was in the fifth decade, with 19 cases (15.8%) among males, and after the sixth decade, with four cases(3.3%) among females. Mean age was 57.7 years. Diverticulum size of 5-10mm in diameter was predominant 2% of cases) ; average diameter was 5-6mm. The incidence of colonic diverticulosis was 5.1 times more frequent in the right colon(101 cases) than in the left (20 cases). CONCLUSION: The overal overall incidence of colonic diverticulosis has continually increased; in addition it has also recently increased slightly in left-sided colon. This is thought to be due to various factors, both congenital and acquired, including longer life with good health care, constipation, irritable bowel syndrome, stress and the tendency of eating patterns to more closely resemble those of the west.

An 8-year-old male was admitted because of dysphagia and substernal pain suffered while eating followed by postprandial vomiting for 2 years. He was always hungry due to postprandial vomiting and willing to eat again just after vomiting. After this meals, he used to jump up and down to shake off the substernal discomfort. A narrowing of the gastroesophageal junction was noted by esophagogram. Manometry revealed high Lower esophageal sphincter (LES) pressure (51.6mmHg), incomplete LES relaxation during swallowing, loss of esophageal peristalsis and a positive pressure of the esophageal body compared to intragastric pressure. After the 1st balloon dilatation, symptoms were much improved even though LES pressure still remained high (37.2mmHg). About 2 months after the 1st balloon dilatation, symptoms relapsed and we managed him with a 2nd balloon dilatation. Symptoms were more improved than after the 1st dilatation and LES pressure normalized as well. Since the 2nd dilatation, symptoms have not recurred for 3 years. We present an 8-year-old boy with achalasia successfully managed by the use balloon dilatation.

Malignant epithelial neoplasm usually occurs in postmenopausal women, with less than 10% of cases occurring in women under the age of 20. In patients below this age, the majority of ovarian tumors are of germ cell origin and malignant ovarian epithelial tumors are uncommon. We report US & CT imaging in a case of mucinous cystadenocarcinoma in a 17-year-old nullipara who complained of amenorrhea for 45 days and a palpable mass.

PURPOSE: To predict pulmonary arterial hypertension by comparing the extent of honeycombing lesion with the diameter of main pulmonary artery (MPA). MATERIALS AND METHODS: We retrospectively reviewed 21 patients (20 men, one woman) who showed honeycombing lesion on HRCT, and also analysized a control group of 30 (29men, one woman) who had no cardiopulmonary symptom and no abnormality on chest CT. On Chest HRCT, we scanned at four levels [1)aortic arch, 2) bifurcation of bronchus, 3) mid-portion of left ventricle, 4) dome of right diaphragm], and two radiologists then evaluated the proportion of honeycombing lesion within the entire lung field. According to the extent of this, we divided the patients into five groups [<20% (I), 20-39% (II), 40-59% (III), 60-79% (IV), > or = 80% (V)], and then divided Group I into two subgroups [<10 % (I|1), 10-19% (I-2)]. Using contrast-enhanced routine CT, the main pulmonary artery (MPA) was measured at its the widest diameter perpendicular to the long axisat the level of its bifurcation. RESULT: In group I (n=11) MPA was 28.4+/-2.6mm ; in group II (n=6), it was31.7+/-2.0mm ; in group III (n=2), 33.5mm ; in group IV (n=1), 33mm ; and in group V (n = 1), 39mm. In subgroup I-1MPA was 26.1+/-1.9mm, and in subgroup I-2, it was 29.8+/-1.6mm. In the control group, MPA was 25.1+/- 2.0mm. CONCLUSION: The extent of honeycombing lesion is closely related to the change in diameter of the MPA. Honeycombing lesion extending over more than 10% of the lung field may lead to pulmonary arterial hypertension.

It was the late Chosun Dynasty and Daehan Empire era that Western Medicine has firstly been introduced to Korea, previously operating on a basis of Korean traditional medicine. Western Medicine has been introduced by American missionary and Japanese Imperialism. An introduction of Western Medicine made it feasible to proceed new type medical care including operation, leading to require a new form of medical facilities. In the beginning, new facilities were constructed by Japanese Imperialism. Other hand many of facilities including Severance Hospital were established by missionaries. First of all, Daehan Empire established and managed a modern type of medical facility named "Jejoongwon" in 1885 as a government institution hospital. The Red Cross Hospital built in 1889. Afterwards, Jejoongwon and the Red Cross Hospital were taken over to missionary hospital and Japanese Imperialism, respectively. Japanese Imperialists firstly have protected their nationals residing in Chosun but have proceeded care a few Chosun people to exploit medical treatment as a mean to advertise superiority of the Empire of Japan. The facility that has firstly been established and managed was Jeseang Hospital in Busan in 1877, leading to establish in Wonju, Wonsan, and Mokpo. Afterwards, Japan has organized "Donginhoi" as a civil invasion organization, leading for "Donginhoi" to established "Dongin Hospital" in Pyeongyang, Daegu, and Seoul. Since 1909, governmental leading medical facility named Jahye Hospital was established according to an imperial order, leading to establish 32 hospitals all over the nation. American missionaries have established and managed 28 hospitals started from Severance Hospital built in 1904. However, Chosun doctors started to having educated and opening up their own hospital since 1920, leading for many of medical facilities to be established, but most of them have taken different roles followed by 6.25 War and economic development period. However, some of them are currently under protection as cultural assets, and some of them are now preserved. Buildings have originally been structured of wood as a single story in the beginning, but bricks started to be steadily used, leading to build two story building. Each of clinic department started to be separated since 1920, establishing operation room and treatment room. Now, a change of perception as to buildings that need to be preserved and an attention from government and doctors are required since modern medical facilities keep disappearing.

BACKGROUND AND OBJECTIVES : In head & neck cancer, the conventional CT and MRI are useful methods in imaging the anatomical structures of cancer, but they have limits in estimating sensitivity and specificity. To overcome these limits, PET-CT, an imaging technique using metabolism emitting from cancer tissues, was introduced. This study was aimed to evaluate the clinical values of PET-CT by comparing the PET-CT of the conventional CT/MRI, with respect to imaging primary lesions, finding metastatic cervical lymph nodes, and discovering any tumor or recurrence. MATERIALS AND METHOD : Seventy patients, who were diagnosed with head and neck cancer, were selected from Inha Hospital from March, 2004 to July, 2005. For every patient selected, a retrospective analysis was done by medical record review. The studied patients were divided into group 1 and 2. Group 1 was composed of patients that had preoperative evaluation for staging, group 2 with follow-up patients after primary treatment. In group 1, the analysis was done by comparing pathohistologic results from PET-CT to CT/MRI findings and in group 2, radiologic imaging studies were compared by follow-up imaging or clinical manifestation after 6 months. RESULTS : For the primary sites, 22 cases were laryngeal cancers, and 17 cases were thyroid. For primary site cancers and metastatic lymph nodes in group 1 and 2, there were no statistical differences of sensitivity, specificity and predictability between CT/MRI and PET-CT imaging. CONCLUSION : We were not able to prove the clinical values of PET-CT, since PET-CT had no meaningful differences from the conventional methods in imaging primary lesions, finding metastatic cervical lymph nodes, and follow-up.

Gallbladder cancer (GBC) is the most common primary hepatobiliary carcinoma and the sixth most common gastrointestinal malignancy. Adenocarcinoma accounts for the vast majority of GBCs (80–95%), whereas squamous cell carcinoma constitutes only 0–3.3% of GBCs. A 69-year-old man was suspected to have GBC with a cholecystoduodenal fistula on an abdominal computed tomography scan. He underwent esophagogastroduodenoscopy, which revealed that the duodenum was obstructed by the mass. Duodenal and biliary stents were successfully placed using endoscopic retrograde cholangiopancreatography. Pathology obtained from the duodenum revealed the mass to be a squamous cell carcinoma.

Congenital mesoblastic nephroma (CMN) is the most common renal tumor in the first year of life. Here, we present unique findings of cellular variant CMN seen on prenatal and postnatal MRI with diffusion-weighted imaging (DWI).The mass was well-visualized on prenatal MR DWI with diffusion restriction in the solid portions. After excision of the mass, follow-up whole body MRI with DWI helped identify local tumor recurrence with suspicious liver metastasis. This hepatic lesion also showed diffusion restriction.
