The injury of the epiphysis or epiphyseal plate produces undesirable effects on the normal growth of the bone, such as bone bridge, growth arrest and angular deformity. Authors performed vascularized fibular epiphysis and epiphyseal plate transplantation in 7 years old girl, who received the excision of the exostosis on distal ulna, followed by progressive varus deformity of right forearm and growth arrest of distal ulna.

In man the epiglottis is a thin lamella of yellow elastic cartilage. The upper part is free and is known asleaf and lower part participates in the formation of the anterior wall of the vestibule of the larynx. Theipithelial covering extends forwards onto the base of the tongue over the medial glossoepiglottic folds. The sidesof epiglottis are connected with the cartilages of Wrisberg and arytenoid cartilage by the aryepiglottic fold. Inview of these anatomical complexities, the function and physiology of the epiglottis have been debated sinceMagendi(1815), who proposed the theory that the epiglottis acts as a flap valve to prevent food entering thewindpipe, and who found that he could remove the free part of the epiglottis in dog without spoiling the dog.Follwoing the introduction of laryngoscopy(Garcia, 1815; Liston, 1840; Czermark, 1861) and modern cineradiographicequipments in 1950's, the anatomy and physiology of epiglottis has become much clearrer. Age as it is seen on thelateral x-ray of the neck. In the present study we have made an attempt to systematically analyze aging changes ofthe epiglottis in the lateral x-ray of the neck in 245 healthy adults. The age ranged from 16 to 65 years old.Based on our observation the epiglottis was classified into type A, B, and C according to their curvatures. Thus,type A represented those with posterior curvature, type B those with straight epiglottis and type C anteriorcurvature. Type C was sudivided into I, II and III according to the degree of curvature. Thus, type C-I, C-II andC-III represented mild, moderated and marked anterior curvature, respectively. Type A epiglottis was found in thesecond, third and fourth decades and type C-III in the older age group. Type A was least comon and type C mostprevalent. It seems that the epiglottis inclines anteriorly with backward curvature with age (p<0.0001).

Glucocorticoids are usually given according to a standard dosing protocol regardless of individual difference. We evaluated the pharmacokinetic characteristics of methylprednisolone and the degree of interpatient variation in stable Korean renal transplant recipients during the period of 15-21 days after transplantation. This study included 23 renal transplant recipients, 13 males and 10 females, who received kidneys from living donors with stable graft function and without episode of acute rejection. On the study day at 8 A.M., 16.3mg of ethylprednisolone sodium succinate (i.v.) was administered to each patient instead of usual dose (20mg) of prednisolone (p.o.) after sampling of 7cc of baseline blood and additional blood samples were drawn after starting infusion. Plasma was separated and analyzed for methylprednisolone level using high performance liquid chromatography (HPLC) assay, and parameters for pharmacokinetics were calculated. There was significant interpatient variation in the pharmacokinetics of methylprednisolone in our patients group. There was no significant difference in the pharmacokinetic parameters between patients with and without side effects of steroid. Korean renal transplant recipients had higher volume of distribution than black renal transplant recipients; lower clearance than white renal transplant recipients; longer t1/2 than both black and white renal transplant recipients. Even if the number of patients included in this study was too small to reach conclusion, the differences in the pharmacokinetics of glucocorticoids do not seem to be a significant risk factor for side effects of steroid after transplantation. It may be necessary to individualize the dose of a glucocorticoid to achieve an optimal effect and also we need to establish a new steroid regimen protocol for Korean renal transplant recipients.

Primary cutaneous aspergillosis is rare. In this report we describe primary skin infection by Aspergillus in 9 children with leukemia. The skin lesion was characterized clinically by erythematous macule and papule associated with pain and itching, followed by a rapid progression to ulcer and central black eschars with raised erythematous border at the site of venipuncture, insertion of intravenous cannula, or where arm boards had been taped to extremities. Diagnosis was confirmed by skin biopsy and wound culture. Positive revealed in 6 patients, including A. glaucus in 2 cases, A. flavus in 1 case. Treatment consisted of temporary withdrawl of anticancer chemotherapy, intravenous amphotericin B, oral flucytosine, itraconazole and/or rifampin. One patient recovered completely without antifungal medication with resolution of leukopenia. Six of eight treated patients recovered. One patient discharged against medical advice, while cutaneous aspergillosis was improving. One patient died with persistent skin lesion and neutropenia. We conclude that primary cutaneous aspergillosis is increasingly recognized in association with intravenous cannula, intravenous puncture or prolonged contact with arm boards in immunocompromised patients, and that this serious disease can be treated successfully with appropriate management.

Leukemic infiltration of the testes has been relatively rare disease. But increased survival due to advance in the treatment of childhood leukemia has been associated with an increase in incidence of leukemic infiltration of the tests. Six of 66 male children with acute lymphocytic leukemia and 2 of 2 male children with leukemic transformation on non-Hodgkin's lymphoma, who have been admitted to our pediatric department during past 7.5 years period, from January, 1974 to June, 1981 developed testicular leukemia. This represents an incidence of 11.8% and the median age was 6.6 years(9 mo. to 14 yrs). All patients were symptom free despite testicular enlargement. Testicular enlargement was initial presenting manifestation in two patients. The enlargement was unilateral in 5 and bilateral in 3. Initial white blood cell count was greater than 100,000/mm3 in five patients and was less than 10,000/3 in other three. Microscopic findings on specimens were leukemic infiltration mainly in the interstitial spaces and atrophy of spermatogenic cells. Four patients developed testicular relapse during bone marrow remission. Hepatosplenomegaly and lymphadenopathy were present in 5 and 6, and these appeared to imply an increased risk of testicular relapse. The median duration from diagnosis to testicular relapse was 33.5 months(2 mo. to 93 mo.). Three patients developed subsequent relapses(CNS; 2, BM; 1) 1.5 to 26 months after the testicular relapse, the median interval being 14.5 months. Radiotherapy with chemotherapy has resulted clinical improvement, but only one patient showed long survival without relapse.
