Wiskott-Aldrich Syndrome is an X-linked disorder characterized by recurrent infection, thrombocypenia and eczema. Various defects in cell-mediated immunity and deficient antibody reponse to carbohydrate antigens have been described. We experienced a case of Wiskott-Aldrich Syndrome of 28 months old male patient. He has been suffered from multiple petechiae with bleeding, recurrent pyogenic infections and generalized eczema since 3 months of age. Immunological abnormalities are as follows: 1) Serum IgM was gradually decreased, while IgA and IgE were increased. 2) Antibody response against polysaccharide antigen (PRP) was not observed after 3 times of PRPT immunization. 3) CD4/CD8 ratio was reversed (0.6). 4) Proliferative response of mononuclear cells was significantly reduced, and CMI skin test also showed negative results. A brief review of literature was made.

Melanosis coli is characterized by a dark brownish discoloration of the colonic mucosa. Its pathogenesis is still unknown. Recently it was proposed that the apoptosis of mucosal epithelium due to habitual use of laxatives play an important role for induction of melanosis coli. We studied clinicopathologic aspects of 12 cases of melanosis coli and analysed the histochemical and immunohistochemical characteristics of them. Results are as follows. : Mean patient's age was 53.5, and the male:female ratio was 4:8. Nine patients had a history of constipation, and all of these had administrated various kinds of laxatives. The severity of discoloration was correlated with the duration of constipation and age. There was no difference of anatomical distribution in colon. Other remarkable mucosal lesions were not accompanied. On pathologic examination, all cases showed frequent yellow-brown pigment laden cells in lamina propria. These pigments were positive for periodic acid Schiff stains, Fontana Masson stains, and Victoria blue stains, however they were negative for prussian blue stain. On immunohistochemical stainings pigmented cells were positive for CD68, and negative for S-100 protein and neuron specific enolase. These results indicate that they are macrophages. On ultrastructural examination pigmented cytoplasms were filled with variable sized electron dense granules including irregulary round deformed membranous structures, lipid vacuoles. Apoptosis of mucosal epithelium was noted in 5 cases. These findings suggest that apoptosis is the significant pathologic process in the progression of some cases of melanosis coli.

Fifty-nine histologically proven cases of carcinoma of the larynx and hypopharynx were examined with CT forthe staging before surgery or radiation therapy and the findings of primary disease and neck metastasis wereanalyzed. Local extension of the tumor can be easily evaluated with CT and findings of lymph node metastasis ofneck were seen in 33 cases(79%) of all. Among cases of neck metastasis, peripheral contrast enhancement of thelymph nodes were demonstarated in 26 cases (79%).

Pretwisting the patellar tendon graft has been advocated hy many authors. Lambert has described a 90 degrees pretwist to benifit the fat pad vascular supply as well as to "" simulate the helicoid course of the ACL "". This technique has also been recommended to fascilitate fixation. Jackson has recommended a 90 pretwist to decrease the possibility of abrasive wear on the tunnel edge, and also to fascilitate fixation as much as a 180 degrees pretwist has heen recommended. However, in spite of all these recommendations, little work has been done on the effect of such pretwisting on the biomechanical behavior of patellar tendon grafts. The purpose of this study is to discover, by experiment, the effects of a 360 degrees external rotation pretwist on the following tensile mechanical properties of canine central 1/3 patellapatellar tendon-tibia complex : (a) ultimate stress, (b) ultimate strain, (c) average elastic modulus, and (d) strain energy density. Five groups of each S specimens were divided as group 1 (0 degrees external rotation), group 2 (90 degrees external rotation). group 3 (180 degrees external rotation), group 4 (270 degreesexternal rotation), and group 5 (360 degrees external rotation). The direction of pretwist meant the twist of tibia around patella. The effects of pretwist were analyzed using parameter one-way analysis of variance (ANOVA)(P1) and nonparameter Kruskal-Wallis one-way analysis of variance (ANOVA)(P2) with repeated measures followed by Scheff multiple comparison test. A p values of < 0.05 was considered statistically significant. Among each groups ultimate stress (P1=0.059, P2=0.095), ultimate strain(P1=0.154, P2=0. l65), and average elastic modulus(P1=0.814, P2=0.818) were not statistically significant. Only strain energy density was the statistically significant difference between group 2 and group 5(P1=0.008, P2=0.022). As a result, there were observed that the ultimate stress and strain energy density were decreased and ultimate strain was decreased but there were not statistically significant differences hetween groups because of the small number of samples, and there will be advantages for graft to avoid ahrasive wear on the tunnel edge and lateral femoral condyle. But, more studies are needed for human being in the future.
