Torn discoid lateral meniscus has been numerously reported in diagnosis and treatment. But discoid meniscus in children of which clinical pictures were thought to be different from adults was rarely known. We experienced 2 cases of discoid meniscus tear in children whose ages were below 4 years old and report with references.

This paper introduces a safe arthroscopic technique passing through the posterior septum from the posteromedial cotnpartment to the posterolateral compartment, or vice versa, without damage to the PCL, capsule, and/or neurovascular structures. The posterior septum is triangular, bounded by the PCL anteriorly, the posterior portion of the femoral I.ntercondylar notch superiorly, the posterior capsule posteriorly, and devicles the posterior compartment of the knee joint into the posteromedial and posterolateral compartments. The middle genicular vessel pierces the posterior capsule and runs along the superior border of the posteriorseptum. There are no dangerous important structures at the central portion of the triangle of the posterior septum. This arthroscopic posterior portal technique is devided 4 steps. The first step is to make a posteromedial portal under direct arthroscopic visualization. The second step is to make a posterolateral portal. The third step is to make a hole at the posterior septum and to examine throposterolatera] compartment. The fourth step is to examine the posteromedial compartment through the posterior septum. This technique provides complete visualization of the posterior compartment of the knee joint, including the posterior aspect of the both femoral condyles, the posterior hom of both menisci, the PCL, the meniscofemoral ligament (Wrisberg s ligament), the posterior aspect of the pop liteal tendon, the femoral attachment of the ACL, the posterior septum and the posterior capsule. We have used this technique from October, 1994 to June, 1996 in 58 knees; arthroscopic total synovectomy in 43, removal of the loose bodies located behind the PCL in 8, PCL re!construction in 4, meniscal repair with all inside suture technique in 3. In conclusion, this procedure is very helpful in performing arthroscopic total synovectomy in chronic, acute, hemophilic, and crystal induced synovitis, in removing encapsulated loose bodies located behind the PCL, and in suturing peripheral tears of the posterior hom of the medial rneniscus with an all inside suture technique.

The technique of the arthroscopic total meniscectomy of discoid meniscus is very difficult. Ikeuchi(1982) reported a technique of arthroscopic total meniscectomy of the lateral discoid meniscus by removal of 2/3 of the anterior part of the meniscus first and then by morselization. The purpose of this paper is to report a technique of arthroscopic total meniscectomy of the lateral discoid meniscus as a whole. During the period from October 1982 to October 1984, we had 12 experiences of arthroscopic total meniscectomy of the discoid meniscus and found good results, that is, little postoperative pain, short period of hospitalization and early restoration of joint motion without physical therapy. Complications are 3 cases of symptomless slight lateral instability and 4 cases of hemarthrosis.

A 4-year-old boy has had a solitary sclerotic depressed plaque on the right anterior chest since birth. The histopathologic findings are consistent with morphea profunda: thickening, hyalinization, and homogenization of collagen bundles in the dermis and subcutaneous tissues, admixture with a prominent lymphocytic and plasma cell infiltrate, and sweat glands en-trapped between the thickened collagen bundles. We report a case of congenital solitary morphea profunda.

Core tissue for histologic study is believed by many pathologists to be more diagnostic than material from needle aspiration. Recently introduced automated biopsy gun simplifies core biopsies with increased quantity and quality of samples. Authors performed 38 percutaneous biopsies from 38 patients with 18G automated biopsy guns under US guide. Diagnostic target tissues were obtained in 33 biopsies(87%), inadequate tissues in 4 (11%), and adequate but not of target tissue in 1(3%). There was no major complication requiring treatment, but pain needing analgesics and pain with nausea/vomiting were experienced in 2 and 1 biopsies respectively. Average number of needle passes was 1.5(1-5) We concluded that US-guided gun biopsy was a easy and safe way to obtained tissue samples of good quantity and quality, especially useful in hospitals without constant availability of specialists in cytopathology.

The minor fissure is an important anatomical landmark in the localization of the pulmonary diseases. For the evaluation of the normal feature of the minor fissure, we analyzed the high-resolution computed tomography (CT) scans in 51 normal patients. The purposes of this study are to evaluate the normal appearance of the minor fissure on high-resolution CT scans and to compare it with that on the coventional CT and chest radiographs. We analysed the morphologic feature of the minor fissure on the high-resolution CT scans in 51 normal patients, and compared it with that on the conventional CT scans. On the high-resolution CT scans, we particularly paid attention to the completeness and types according to Berkmen classification. And finally, we compared the types determined by the high-resolution CT scans with those by the plain radiographs. In most patients (n=47), the minor fissure was seen as a hyperattenuating line or hand on the high-resolution CT scans. In contrast, it was mostly seen as a lucent zone on the conventional CT scans (n=44). Of 47 patients having a hyperattenuating line or band on the high resolution CT scans, the minor fissure was considered to be complete in 17 patients (36%), and incomplete in 30 patients (64%), who had defect at medial portion of the minor fissure. The most common type of the minor fissure seen on the high-resolution CT scans was type I variety (n=23), followed by type IIa (n=10) and type II (n=8). We could not determine the type in six patients. The type determined by the high resolution CT scans was highly well correlated with that determined by the plain radiographs (p<0.05). In conclusion, the minor fissure was seen on CT studies as variable appearances and high-resolution CT scans were superior to the conventional CT scans in the evaluation of the minor fissure. The type of the minor fissure determined by the high-resolution CT scans were well correlated with those seen on the radiographs.

Vaccination is defined as the introduction of vaccine into the body for the purpose of inducing immunity. Vaccine contain many antigens, e.g., active antigen in DTP, tissue culture fluid in the suspension of vaccine, aluminum complexes in MMR, preservatives, anti-infectives, and antibiotics which induce many allergic reactions. B.C.G vaccine induce specific and nonspecific dermatological complications on inoculation site or out of vaccination. DPT or TT vaccine induce infection site granuloma due to aluminum on inoculation site, angiolymphoid hyperplasia with eosinophilia, and livedoid skin necrosis. Hepatitis B vaccine can induce many dermatological complications, e.g., urticaria and angioedema, erythema nodosum, systemic lupus erythematosus, lichen planus and thrombocytopenic purpura. Gianoti-Crosti syndrome is caused by MMR vaccine and influenza vaccine. Sweet's syndrome and acute exanthematous pustular dermatitis are developed after pnuemococcal vaccintation. Herpes zoster can be developed after chicken pox vaccination. Erythema and edema can be developed after injection of botulinum toxin. Benign and malignant tumor can be induced by various vaccination, too.
