Purpose : Parents' genetic information plays an important role in their children's genetic expression. Human chromosome has 23-paternal chromosomes and 23-maternal chromosomes. Parental chromosomal translocation can induce clinical problems in their children because of imbalance in genetic information. We intent to analyze the cytogenentic and clinical features about children with maternal balanced translocation between chromosome 15 and 18. Methods : We detected by one family's FISH study of chromosome 15. We have evaluated children born to clinically normal parents about peripheral bood analysis, endocrine, metabolic, radiologic study, electroencephalogram and social & intelligence scale. and We analysis their clinical manifestation by hospital records. Results : Patient's father and elder sister are normal clinically and genetically. Her mother's chromosome show balanced translocation, 46, XX, t(15;18)(p11.2;p11.3). One child has 46, XX, der(18) t(15;18)(p11.2;p11.3), mental retardation, growth retardation, speech & social developmental delay, recurrent infection and mild mitochondria dysfunction. Her young brother has 46, XY, der(15) t(15;18) (p11.2;p11.3), mental retardation, aggressive behavior, obesity and speech developmental delay. Conclusion : In this study we observed the children with developmental delay, dysmorphic facial features, mental retardation, growth retardation associated with growth hormone deficiency and aggressive behavior due to unbalanced translocation between chromosome 15 and 18.

MR findings in nine patients(three female, six male) with neuro-Behcet's disease were retrospectively analyzed. NeuroBehcet's disease was diagnosed on the basis of typical clinical symptoms. Involved site, pattern, signal intensity, and contrast enhancement pattern on MRI were evaluated. In addition, follow up MR imaging was performed in four patients. The midbrain(7/9), internal capsule(7/9), pons(6/9), thalamus(6/9), basal ganglia (5/9), middle cerebella peduncle(4/9), medulla oblongata(2/9), and subcortical white matter(2/9) are involved on MRI. The size of lesions was 1cm to 3cm and their margin was ill-defined and patchy. Inhomogeneous high signal intensity on the T2-weighted images and low signal intensity on T1-weighted images was seen respectively. In four of nine cases, there was focal enhancement. On follow up MR imaging, improvement or recurrance of the lesions was found. Also in two cases of follow up cases, there was artophy in brainstem and(or) middle cerebellar peduncles. In conclusion, MR imaging with systemic clinical symptoms is useful for diagnosing neuro-Behcet's disease.

Necrotizing lymphadenitis was first recognised as a self-limiting lymphadenitis by Japanese workers in 1972. It is a distinct clinicopathologic entity, but can be mistaken as malignant lymphoma. We have studied clinicopathologic features in 15 cases of necrotizing lymphadenitis. This disease occurs predominantly in young adult. Male-female ratio is 2 : 1. The commonest presentation is lateral cervical lymphadenopathy. Pain, tenderness, and fever can be seen. Biopsy of the lymph nodes from all patients demonstrates the characteristic histologic features : multifocal, relatively circumscribed nodules in the cortex and/or paracortex, consisting of a mixture of activated large lymphoid cells, histiocytes and small lymphocytes. Numerous karyorrhetic debris are present. Neutrophils and plasma cells are strikingly absent.

Purpose : Recently, it has been reported that the prevalence of mycoplasam pneumonia in infants is increasing. We studied the change of prevalence and clinical features in infants for recent three years. Methods : We evaluated the clinical records of 206 patients diagnosed as mycoplasma pneumonia during Mar. 2000~Feb. 2003. We retrospectively analyzed epidemiologic, clinical, serologic and radiologic difference between children younger than 24 months and others. Results : Among 206 patients, 111 were boys and 95 were girls. Mean age of onset was $5.12{\pm}2.91$ years and lowered annually(P>0.05). 28 patinets(13.6%) were younger than 24 months and annual prevalence in this group increased(P<0.05). Main clinical features included cough, fever, coarse breathing sound(=sputum), rhinorrhea and dyspnea. There was no clinical difference between children younger than 24 months and others, except for rhinorrhea and dyspnea which more developed frequently in children younger than 24 months (P<0.05). There was also no serologic and radiologic difference for these groups. Conclusion : Annual mean age of onset lowered and annual prevalence of younger than 24 months increased with mycoplasma pneumonia. Therefore, we need careful attention to differentiate Mycoplasma pneumoniae as causal organism of pneumonia in children younger than 24 months.

The unicystic ameloblastoma deserves separate consideration on the basis of its clinical, radiologic, and pathologic features and its response to treatment. It refers to those cystic lesions that show clinical, radiographic, or gross features of a jaw cyst, but on histologic examination show a typical ameloblastomatous epithelium lining part of the cyst cavity. The lesion is most commonly found on the mandible posterior area, and often asymptomatic, although large lesions may cause a painless swelling of the jaws. The lesion typically appears as a circumscribed radiolucency that surrounds the crown of an unerupted molar. These are usually considered to be a dentigerous, residual cyst on the relationship of the lesion to teeth in the area. Three histopathologic variants of unicystic ameloblastoma may be seen. 1) Luminal type, 2) Intraluminal type, 3) Mural type. In this case, these tumor was treated as cysts by enucleation with iliac bone graft, and the diagnosis of ameloblastoma is made after microscopic examination of the presumed cyst.

Purpose To assess the clinicoradiological features of pulmonary cryptococcosis in immunocompetent patients. Materials and Methods This retrospective study included immunocompetent patients who had been diagnosed with pulmonary cryptococcosis on the histopathologic exam and underwent chest CT between January 2008 and November 2019. Imaging features were divided into major imaging patterns, distributions, and ancillary imaging findings. Univariable analysis was performed to evaluate clinicoradiological features according to the presence of serum cryptococcal antigen. Results Thirty-one patients were evaluated (mean age: 60 years, range: 19-78 years). A single nodular lesion confined to a single lobe was the most common imaging pattern (14/31, 45.2%). Serum cryptococcal antigen tests were performed in 19 patients (19/31, 61.3%). The presence of serum cryptococcal antigen was observed in six patients (6/19, 31.6%), all of whom showed a consolidation-dominant pattern. The presence of serum cryptococcal antigen was significantly associated with the consolidationdominant pattern compared to those associated with a nodule-dominant pattern (p = 0.011). Conclusion A combination of CT findings of consolidation and a positive serum cryptococcal antigen test may be helpful for diagnosing pulmonary cryptococcosis in immunocompetent patients.

Ingestion of grapes or raisins has been reported to the occurrence of acute renal failure (ARF) in dogs, although the mechanism remains undetermined. The prognosis often depends on the severity or clinical course of the disease at the time of presentation and is poor if the dog becomes anuric phase. To explore the characteristics and outcome of ARF caused by grape or raisin poisoning, sequentially collected data, from 2005 to 2008, of the Veterinary Medical Teaching Hospital at the Kangwon National University for clinical evaluation were retrospectively analyzed. Of the 11 clinically affected dogs, 4 cases made a full recovery, 3 died and 4 were euthanized. All but one case (raisin ingestion) had a history of grape exposure, but the exact quantity of fruit ingested was not known. The female dogs accounted for 72.7% (8 cases). Overall, the mean age was 5.3 years (range 0.2-11.3 years), and the mean body weight was 4.1 kg (range 1.4-13 kg). The average duration of hospital stay was 7.1 days (range 2-22 days). Vomiting and anorexia was reported in all dogs. Diarrhea (4 cases), oliguria (5 cases), and anuria (4 cases) with or without isosthenuria were also reported. Five dogs of 11 had mild to moderate anemia, with a decrease in packed cell volume and hemoglobin. All dogs had elevations in serum phosphorous, creatinine, and blood urea nitrogen values, but calcium values were variable; 2 dogs with hypocalcemia, 2 dogs with hypercalcemia, and the remaining 7 cases within reference interval. Dogs (n = 8) with measured on blood gas parameters had metabolic acidosis. In addition, higher serum enzyme activities were observed; amylase in 8 (72.7%) dogs, alkaline phosphatase in 7 (63.6%) dogs, and alanine aminotransferase in 5 (45.5%) dogs. Non-survived dogs revealed lower counts of platelet and lymphocyte subpopulation, as compared to the survived dogs.

Purpose : DNA ploidy pattern was shown to correlate with several clinicohistologic findings in several tumors. Aim of this study was to evaluate the correlation of the clinicohistologic findings in colorectal cancer and the failure pattern in rectosigmoid cancer with DNA ploidy. Materials and Methods DNA flow cytometry using the Hedley methods on paraffin embedded specimen from 117 patients with colorectal cancers after curative resection was peformed. We tried to find the correlation between DNA ploidy and various clinicohistologic findings. And then the correlation DNA ploidy and the failure pattern in 75 patients of rectosigmoid cancer was analized. Results : Forty samples (34.2%) from tumors gave aneuploidy histogram. There was no significant difference in the frequency of DNA aneuploidy in terms of age, sex, depth of invasion, location and Dukes stage. But there was a significant correlation between DNA ploidy and the failure rates in Dukes stage B rectosigmoid cancer (P=0.048). Conclusions : These findings suggest that DNA ploidy pattern shows the correlation with the treatment failure rates in Dukes stage B rectosigmoid, but not with many other clinicohistologic findings. However,more patients will be needed to disclose these findings.

Purpose : The prevalence of Reye syndrome has decreased since late 1980's. But we report that recently there were concentrative attacks of Reye syndrome after acute enteritis during the neonatal period. Methods : Clinical symptoms and laboratory results(quantitative organic acid analysis, routine chemistry, arterial blood gas analysis, serum ammonia) of seven patients admitted at the Samsung Medical Center, Sanggye Paik Hospital, Wonju Christian Hospital and Chuncheon Sacred Heart Hospital, referred from Jan. 2005 to Apr. 2005, were analysed retrospectively. The major clinical symptoms were derived from the patients' clinical records sended with urine samples and quantification of organic acids were done with gas chromatography and mass spectrometry. Results : The mean age of seven cases is 18 days and the major preceding symptoms were gastrointestinal symptoms(vomiting, diarrhea, refusal to feeding). The major clinical symptoms were clouded conciousness, repiratory difficulty, vomiting, seizures, and diarrhea. One patient died; that patient's serum ammonia was twenty times higher than normal. Conclusion : The seven patients were neonates. Reye syndrome has been known to be closely related with upper respiratory infections as a preceding disease and to internal use of aspirin, but in our study, the major preceding disease of the seven cases was gastrointestinal infection and none of these used aspirin.
