PURPOSE: Differential diagnosis of solitary pulmonary nodule with cavity includes lung abscess, tuberculoma, bronchogenic carcinoma, metastasis and trauma, etc. We analyzed the CT appearance of tubercuioma presenting as a solitary pulmonary nodule with cavity and describe the findings which suggest tuberculoma in the differential dignosis of soliary pulmonary nodule with cavity. MATERIALS AND METHODS: 25 patients with solitary pulmonary nodule(diameter less than 4 cm) without surrounding parenchymal consolidation on chest radiograph, who had a cavity within the nodule on CT, were included in our study. Density of the nodule, maximal wall thickness, the character of inner and outer wall margin, location of cavity within the nodule, location of the nodule, presence or absence of satellite lesions and calcification were analyzed. RESULTS: Solitary tuberculoma with cavity showed maximal wall thickness more than 15 mm in 40%(10/25) and 5-14 mm in 56%(14/25), eccentric cavitation in 84%(21/25) and concentric cavitation in 16%(4/25), spiculated outer wall margin in 56%(14/15) and Iobulated margin in 32%(8/25), smooth inner wall margin in 60%(15/25) and nodular margin in 40%(10/25). CT density of the cavity wall compared with the chest wall muscle was low in 84%(21/25) and isodense in 16%(4/25). Accompanying satellite lesions were seen in 84% (21/25) and calcification was visible in 28%(7/25). CONCLUSION: The CT findings of solitary tuberculoma with cavity are relative peripheral location, eccentric cavitation, finely spiculated outer wall margin, and mean maximal wall thickness of 13.2 mm, which are also the common features of malignant nodule. However, relative low density of the nodule compared to the chest wall muscle and surrounding satellite lesions can be additional clues favoring solitary tuberculoma with cavity on CT.

PURPOSE: The prevalence of developmental delay is 5-10% of the total pediatric population and early diagnosis and proper intervention are essential but a challenge for clinicians. We performed this study for several purposes. First is to know the distribution & characteristics of developmental disorders in Korea. Second is to identify all possible causes of these disorders through a multidisciplinary diagnostic approach, and thus to find out the clinical variables that are helpful in finding the etiology. And finally to develop a useful protocol that eliminates the cost of unnecessary tests and raises the diagnostic rate of the cause. METHODS: 518 patients(M 349, F 169) were studied who visited Ilsan Hospital Developmental Disorder Clinic(DDC) for the evaluation of developmental delay from April 2001 to Jan 2005. RESULTS: The mean age was 51.5+/-32.9 months, ranging from 2 months to 16.0 years of age with a majority of the preschool children(<6 yr)(79.3%). Phenomenological diagnosis consisted of 133 cases of mental retardation, 122 cases of autistic disorders, 101 cases of delayed language disorders, 27 cases of cerebral palsies, and 91 cases labeled as simple developmental delay requiring follow up due to age less than 2 years of age. Etiologic diagnosis was obtained in 119 cases(22.9%) out the 518 cases of developmental delays. 37 cases of chromosomal anomalies, 23 cases of Periventricular leukomalacia and hypoxic ischemic encephalopathy, 21 cases of syndromes, 7 cases of malformation of cortical development, 4 cases of myopathies, 4 cases of neuropathies, and 4 cases of cerebral infarctions were found. Among the clinical variables, low birth weight, facial dysmorphism, hypotonia, focal neurologic signs, and abnormalities in MRI, chromosome, EEG and EMG studies contributed to the yields of etiologic diagnosis significantly. CONCLUSION: Possible etiology was determined in about 23% of the subjects. The most important part of the assessment for the identification of etiology is thorough history taking, physical and neurologic examination. Neuroimaging study is useful in case of micro or macrocephaly, focal neurologic signs. Genetic studies increasingly produce a yield, when there is family history of inherited disorder and there are dysmorphic features. Routine metabolic screening test has limited utility. Development of a useful screening protocol adequate for Korean situation is required.

The association of gastric tubular adenoma and adenocarcinoma is already well known. Then, are those two pathologic lesions merely incidentally coexisting or does the one evolve to the other? That is a longstanding controversy. Nowadays, as is the case with the colonic tubular adenoma, the hypothesis that gastric tubular adenoma may be a precancerous lesion is generally accepted. However the direct evidences are rare. We report a clear case proving the potential of direct malignant transformation of gastric tubular adenorna through the 9-year close endoscopic follow-up. The developed cancer is well differentiated, surrounded with background tubular adenoma and limited to the submucosal layer.

PURPOSE: We analyzed the clinical outcome of osteosarcoma developed in distal radius and the effect of delayed treatment on prognosis. MATERIALS AND METHODS: Twelve patients with distal radius osteosarcoma were analysed. We categorized patients into two groups of standard treatment or non-standard treatment. The patients of standard treatment group are all stage IIB and non-standard treatment group includes five stage IIB and one stage III. RESULTS: Five-year overall survival and disease-free survival rates of standard treatment group were 100% and 83%. Five-year overall survival rate of non-standard treatment group was 44%. Between two group, there are differences in age, tumor size, surgery type, symptom duration. CONCLUSION: Distal radius osteosarcoma have good prognosis than other extremity osteosarcoma. Survival rate of non-standard treatment group were lower than standard treatment group. Although the prognosis of non standard treatment group is poorer, the duration till death was longer than that of other sites with similar condition. Further multi-institutional study should be needed.

OBJECTIVE: Duchenne muscular dystrophy(DMD) is a X-linked recessive disease and results from mutation in the dystrophin gene. In this study, we evaluate the efficacy of polymerase chain reaction-restriction fragment length polymorphism in prenatal genetic diagnosis of DMD. METHODS: DNA was isolated from DMD family's blood and fetal amniocyte and used to perform PCR-RFLP. In DMD family(3 cases), linkage analysis was tried with 5 RFLP probes. RESULTS: DMDs of the family A had mutiple exon deletions(6, 8, 12, 13, 17). The mother was a heterozygote of pERT84;MaeIII. The male fetus had a same allele and also same exon deletions with the affected males. The pregnancy was terminated at IUP 18 gestational weeks. Pregnant woman of the family B was heterozygote of both pERT84;MaeIII and pERT87-15;BamHI, and pregnant woman of the family C was of pERT84;MaeIII. The both male fetuses , as compared with the affected male of each family, had a different allele. Thus, the fetuses were probably not affected with a confidence level of 95%. CONCLUSIONS: Prenatal diagnosis in prevention of DMD is most important. PCR-RFLP analysis in DMD family is rapid and useful diagnostic tool.

PURPOSE: To evaluate the characteristics of CT findings in differential diagnosis of cervical lymphadenopathy. MATERIALS AND METHODS: We evaluated CT findings of histopathologically proved 32 cases of tuberculous lymphadenitis, 12 cases of nodal lymphoma, 29 cases of metastasis from March 1986 to Dec. 1992, retrospectively. We analyzed age and sex distribution, location of lymphadenopathy, internal nodal density, feature of contrast enhancement, extracapsular spread and nodal calcification. RESULTS: Tuberculous lymphadenitis was more preponderant in young female (mean;32) and CT showed internal low density(91%) with irregular thick marginal enhancement(46.9%), predilection for spinal accessory node(71.9%), and nodal calcification(5/32). Nodal lymphoma showed predilection for internal jugular chain (100%) and had conglomerated homogeneous internal node structures(83%). Metastasis showed old male preponderance (mean :52 years), predilected at internal jugular chain(89.7%),internal low density(93.3%) with regular thin marginal enhancement(44.8%), extracapsular spread(41.4%), and nodal calcification(2 cases of nodal metastasis of papillary type thyroid cancer). CONCLUSION: We concluded that CT evaluation of the chracteristics of lymphadenopathy is helpful for differential diagnosis of cervical lymphadenopathy.

Familial lichen planus is an uncommon disease, and there are 104 cases reported in the English literature. Several theories regarding the etiopathogenesis of lichen planus have been proposed. However, immunological mechanisms and genetic susceptibility have been emphasized the most. Several reports showed HLA analysis in lichen planus patients, and recently 2 cases have revealed an increased frequency of DR1 antigen in patients with lichen planus compared to a control group. We observed two brothers with typical skin lesions of lichen planus of almost simultaneous onset. We confirmed lichen planus by skin biopsies in both brothers and analyzed HLA typing. We also observed the occurrence of DR1 antigen in both of them.

Annals of Dermatology 1997;9(1):11-15
Generalized plane xanthoma is less common and usually involves the eyelids, lateral side of the neck, upper trunk, and extremities. Lesions, however, may appear on any portion of the body. Cutaneous xanthomas may occur in hyperlipidemic and in normolipidemic states. Generalized normolipidemic plane xanthoma is often associated with multiple myeloma, other reticulo-endothelial malignancies and monoclonal gammopathy with unknown significance(MGUS). We wish to report two eases of generalized plane xanthoma associated with IgG monoclonal gammopathy of unknown significance.

In order to find a highly efficient compound against Clonorchis infection, the anthelmintic activity of disophenol, Tremerad (SYD-230), dithiazanine iodide, dehydroemetine-late-release tablets(RO 1-9334/20), niridazole (Ambilhar), hexachlorophene (G-11), Hetol(1, 4-bis-trichloromethylbenzol) and Bilevon (niclofolan) was tested against Clonorchis sinensis experimentally infected rabbits. All drugs showed a progressive increase in efficacy as the dose rate. They were highly efficient against Clonorchis infection if sufficiently high, potentially toxic doses were given. The efficacy was evaluated by the number of detected worms with vital condition at autopsy after the treatment with above drugs. The high efficacy was observed at the following dose rates of each drugs, i.e. disophenol at a single dose of 30 mg/kg, Tremerad at the daily dose of 200 mg/kg for 10 consecutive days, dithiazanine iodide at the daily dose of 50 mg/kg for 6 consecutive days, dehydroemetine at the daily dose of 10 mg/kg for 10 consecutive days, hexachlorophene at the daily dose of 20 mg/kg for 10 to 15 consecutive days, Hetol at the daily doses from 50 to 100 mg/kg for 5 to 10 consecutive days, and Bilevon at a single dose of 8 mg/kg. Moderate effectiveness was shown in niridazole at the dose of 25 mg/kg for 10 days medication. The use of these anthelmintics for the clinical treatment of Clonorchis sinensis infection is discussed.
