A Comparison of Comorbidity and Psychological Outcomes in Children and Adolescents with Attention-Deficit/Hyperactivity Disorder

OBJECTIVE: The purpose of this study was to compare psychiatric comorbid disorders and psychological outcomes in children and adolescents with Attention-deficit/hyperactivity disorder (ADHD). METHODS: Subjects were divided into a child group (aged under 12 years) and an adolescent group (aged 12 years and above). All subjects were diagnosed with ADHD based on the DSM IV diagnostic criteria using the Kiddie-Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Korean Version (K-SADS-PL-K). The K-SADS-PL-K was also used to evaluate those psychiatric disorders comorbid with ADHD. And the Korean version of the Child Behavior Checklist (K-CBCL) was used to examine the subjects' psychological outcomes. RESULTS: The rate of comorbidity in adolescent group was significantly higher than that in the child group. In particular, the adolescent group had a significantly higher ratio of comorbid conduct disorder and mood disorder than the child group. With respect to the predominantly inattentive type and Not Otherwise Specified, the school subscale scores on the K-CBCL for the children were significantly higher than those for the adolescents. CONCLUSION: These results suggest that the psychiatric comorbidity may differ between adolescents and children with ADHD. Therefore when treating adolescents with ADHD, more careful assessment and treatment targeting a range of comorbidities are needed.

Differences of clinical characteristics and phenotypes between prepubertal- and adolescent-onset bipolar disorders.

The aim of this study is to describe the clinical characteristics of prepubertal- and adolescent-onset bipolar disorder (BD) and to identify any clinical differences between patients with prepubertal- and adolescent-onset BD. We analyzed the clinical records of 53 inpatients with BD. These patients were divided into prepubertal-onset and adolescent-onset groups. We also divided the subjects into narrow, intermediate, and broad phenotypes according to the definitions proposed by Leibenluft and colleagues. Of the total sample, 16 patients (30.2%) were in the prepubertal-onset group and 37 (69.8%) were in the adolescent-onset group. Patients with prepubertal-onset BD were more likely to display an insidious clinical presentation, atypical features, and comorbid psychopathology. And the majority of the subjects, especially in the prepubertal-onset group, were classified under the intermediate and broad phenotypes. These results suggest that the clinical presentation of BD with prepubertal-onset is different from that of adolescent-onset BD. It is inferred that a significant number of patients with prepubertal- and adolescent-onset BD do not meet DSM-IV criteria for mania or hypomania from the results of this study.

Tissue engineering of dental pulp on type I collagen / 대한치과보존학회지

The purpose of this study was to regenerate human dental pulp tissues similar to native pulp tissues. Using the mixture of type I collagen solution, primary cells collected from the different tissues (pulp, gingiva, and skin) and NIH 3T3 (1 x 10(5) cells/ml/well) were cultured at 12-well plate at 37degrees C for 14 days. Standardized photographs were taken with digital camera during 14 days and the diameter of the contracted collagen gel matrix was measured and statistically analyzed with student t-test. As one of the pulp tissue engineering, normal human dental pulp tissue and collagen gel matrix cultured with dental pulp cells for 14 days were fixed and stained with Hematoxyline & Eosin. According to this study, the results were as follows: 1. The contraction of collagen gel matrix cultured with pulp cells for 14 days was significantly higher than other fibroblasts (gingiva, skin) (p 0.05). 5. The collagen gel matrix cultured with pulp cells for 14 days showed similar shape with native pulp tissue without blood vessels. This approach may provide a means of engineering a variety of other oral tissue as well and these cell behaviors may provide information needed to establish pulp tissue engineering protocols.

ERCP Findings In Hepatic Clonorchiasis / 대한소화기내시경학회지

An endoscopic retrograde cholangiographic study of 25 consecutive cases of hepatic clonorchiasis was performed during the period from Aug. 1986 to Sep. 1991 Hepatic clonorchiasis was confirmed by stool of examination for Clonorchis sinensis. The findings consist of characteristic filling defects and changes in the intrahepatic and extrahepatic bile ducts. The filling defects due to adult worms are significant diagnostic criteria of clonorchiasis. Its appearance is elliptical and/or round. The change in the intrahepatic bile ducts consisits of dilatation, irregularity(tortousity and elongation) and blunting of termieal branches of bile tree, irregular stenosis, fuzziness and raggedness. The characteristic changes in the extrahepatic bile ducts in clonorchiasis are duct wall irregularities and mild dilatation of bile duct. ERCP is an excellent method to evaluate biliary tree in patient with clonorchiasis because it reveals not only its characteristic findings of clonorchiasis but also its severity and associated lesions.

Report of a Case of Adenomyomatosis of Gallbladder / 대한소화기내시경학회지

Adenomyomatosis of the gallbladder is Characterized by hyperplastic changes including overgrowth of the mucosa, thickening of the muscle wall, and intramural diverticula, crypts, or sinus tracts(Rokitaasky-Aschoff sinuses). The main diagnostic test for the detection of this disease is oral cholecystography but it's use is being decreased. Recently, Ultrasound, ERCP, and CT have been used for diagnosis. We present a report of case in whom ademomyomatosis of gallbladder was disgnosed on ultrasound and ERCP and confirmed by surgery. The essential feactures of ultrasound and ERCP diagnosis are discussed.

Endoscopic Findings and Its Diagnostic Accuracy in Gastric Cancer Confirmed by Surgery / 대한소화기내시경학회지

In order to evaluate the accuracy of endoscopic findings in the diagnosis of gastric can the endoscopic findings of gastric lesion were compared with the macroscopic and pathologic findings of excised identical lesion. 105 operated gastric cancer paitients (advanced cancer 95 cases, early cancer 10 cases) who were diagnosed endoscopically at Pusan National University Hospital from January 1983 to August 1987 were studied. The results were as follows; 1) The accuracy of endoscopic findings were 94.7% in the advanced gastric cancer, and 45.5% in the early gastric cancer. 2) The accuracy of gross findings endoscopic and pathologic in advanced gastric cancer were 50.0% in Borrmann type I, 45.0% in Borrmann type II, 73.2% in Borrmann type III, and 66.7% in Borrmann tyye IV. 3) The accuracy of the endoscopy ia morphologic classification of advanced gastric cancer according to pathologic tumor location were 60.0% in C (upper 1/3), 43.9% in M(middle 1/3),76.3% in A (lower 1/3), 55.6% in the anterior wall, 50.0% in the posterior wall, 66.7% in the greater curavature, and 67.2% in the lesser curvature. 4) The accuracy of endoacopy in morphologic classification of gastric cancer to tumor size ware 54.5% in below 2 cm, 54.5% in from 2.1 cm to 4 cm, 65.4% in from 4.1 cm to 6.0 cm, 80% in from 6.1 cm to 8 cm, 75.0% in above 8.1 cm. 5) The accuracy of endoscopy in the morphologic classification according to the pathologic tumor stage in advanced gastric cancer were 55.6% in TNM stage I, 52.0% in TNM stage II, 65.4% in TNM stage III, and 73,7% in TNM stage IV.

Evaluation of radionuclide testicular scan

There has been no adequate diagnostic method for the diagnosis of intrascrotal lesions until recent days. Butafter the development of radionuclide testicular scan, early and relatively accurate diagnosis of the testicularlesions are possible. So the authors analyzed the 32 cases of patients who were examined by testicular scan andconfirmed by follow up study or operation, and the results are as follows; 1. These 32 cases consists of 13 casesod epididymitis, 7 cases of testicular torsion, 4 of cryptorchism, 2 of testicular tumor and etc. The over alldiagnostic accuracy is about 69%. 2. In epididymitis, the diagnostic accuracy is 85%(11/13) and the findings ofscan are increased perfusion in radionuclide angiogram and hot activity noted mainly in peripheral portion of thetesticle in static image. 3. In cases o testicular torsion, diagnostic accuracy is 86%(6/7). Acute torsion showsnormal perfusion in angiogram and round cold area instatic image. But in missed torsion, perfusion is increasedand round cold area wit surrounding hyperemia is noted in static image. Radionuclide testicular scan seems to benoninvasive, inexpensive, easily available and simple to perform with low gonadal radiation dose. So it can bevery useful as the first study in patients with acute testicular symptoms.

A Clinical Observation of the Duodenitis / 대한소화기내시경학회지

A clinieal Observation was done on the 110 cases (male; 52 cases, female; 58 cases) of duodenitis under the gastroduodenoscopic examination among the patients who were performed endoscopic examination because of seeking for the cause of dyspepsia period from Aug. 1981 to Sep. 1981 at Department of lnteral Medicine of BNUH. The results were summerized as follow 1) Normal finding(Grade 0) was highest as 40% in the incidence according to grade of duodenits. Next was moderate (Grade II & II) as 24. 5%, the 3rd was mild(Grade I) as 20% and lowest in severe(Grade IV) duadenitis as 15.5%, 2) Sex distribution of duodenitis showed 37 cases in male and 29 cases in female. And male was slightly higher in incidence than female. 3) Age distribution of duodenitis revealeii 3rd decade and 4th decade were highest in incidence, 30 cases and 28 cases respectively. The order of frequency was 5th decade, 6th decade, 1st decade and 7th decade. 4) Duodenitis was slightly higher in after 4th decade than before 4th decade. 5) The 56 cases of duodenitis except for 1 case were aasociated with gastroduodenal diseases such as gastritis, peptic ulcer or gastric carcinoma. Association of gastritis is highest as 79. 4%. 6) Acurracy of diagnosis in duodenitis on X-ray study was 3 cases in 20 cases. Generally X-ray study was little value in diagnosis of duodenitis.
