CD44 is a family of transmembrane glycoproteins involved in cell-cell and cell-matrix interactions. Expression of CD44 isofonns (splice variants) has been shown to be associated with poor prognosis in several human cancers. We evaluated the expression patterns of the CD44 isofortn (CD 44 splice variant v6) in infiltrating ductal carcinoma of the breast by immunohistochemical and RT-PCR method. Paraffin embedded blocks from seventy-five cases of mastectomized samples were analyzed immunohistochemically using monoclonoal antibody against CD44v6. CD44v6 was detected in fifty-seven cases (76%) of the tumor samples. Adjacent normal myoepithelial cells and ductal epithelial cells revealed focal positive reaction to CD44v6. Thirtytwo cases (80.0%) with lymph nodal metastasis revealed overexpression of CD44v6 monoclonal antibody, but twenty-five cases (71.4%) without nodal metastasis also showed positive reaction to CD44v6 monoclonal antibody, and there is no statistically significant value. Other prognostic factors of infiltrating ductal carcinoma, such as tumor size, histologic grade and hormonal receptors did not show any significant correlation with CD44v6 expression. The RT-PCR studies for 9 cases of infiltrating ductal carcinoma showed the same band patterns both in the normal and tumor tissues. From the above results, it is concluded that the expression of CD44v6 is not a valuable prognostic marker of infiltrating ductal carcinoma of breast.

Teratomas of the fallopian tube are extremely rare, and only about 50 cases have reported in the world literature. Most cases of mature cystic tubal teratoma are asymptomatic and are discovered as an incidental finding on physical or radiologic examination, or at the time of laparatomy. We report a case of mature cystic teratoma of the right fallopian tube which was discovered during pelvic ultrasonogram for antenatal care in a 28 year old woman. Right salpingectomy was performed during cesarean section for cephalo-pelvic distortion at IUP 39 weeks. Gross examination of the right fallopian tube reveals a distended fallopian tube, measuring 8cm in length and 2cm in diameter. On section, it is filled with several small pedunculated nodules and cysts containing sebaceous materials. Microscopically the tumor was seen in continuity with the lining epithelium of mucosal folds. The majority of the tumor was composed of well differentiated mature elements of three germ layers with skin and skin appendages, mature brain tissue, bone, breast tissue, intestinal mucosa and bronchial epithelium.

BACKGROUND: Polymerase chain reaction(PCR) has brought an oppotunity for rapid detection of Mycobacterium leprae in clinical pecimens for the diagnosis of leprosy. Th DNA segment specific to M. leprae was detectable in a matteir of hours and DNA from one orgnisa appeared positive by PCR. However, the PCR tool has not been evaluated using elinical specimeriis from leprosy patients and controls. OBJECTIVE & METHODS: The primers amplifying 372bp segment of rebetitive sequence of M. leprae DNA were used in PCR. Skin biopsy specimens from 102 leprosy patient, and controls were examined for the presence of M. leprae by PCR and the results were aomared with microscopic and histopathologic findings. RESULTS: 1. As a result, of PCR after DNA preparation of M. leprae, six other mycobacteria, ten other bacteria, and skin from leprosy with five other skin biopsy tissues, 372bp DNA fragment was specifically amplified from M. leprae. 2. Dot blot, hybridization of PCR products showed that the 372bp DNA from skin biopsy specimens were derived from M. leprae. 3. As a result of PCR after DNA preparation of 10-fold diluted M. legrae from mouse footpad, PCR gave a positive result as low as one organism. 4. Of 87 specimens in which acid-fast bacilli were found under microcopic examinations 97% had positive PCR results. 5. Of 97 specimens which hadihistopathologic evidences of leprosy 95% had positive PCR results. 6. Of 15 specimens in which acid-fast bacilli were not found under n!icroscopic examinations 73% had positive PCR results. In three of five cases which had neither histopathologic nor microscopic evidences of leprosy had positive PCR results. CONCLUSION: PCR method amplifying 372bp fragment of repetitive seqi,ence was highly sensitive and specific in detecting M. leprae DNA in skin biopsy specimens, thus may be a useful tool as an additive diagnostic method, espcially for cases where microscopic antihystopathologic findings are not definite.

Atypical polypoid adenomyoma(APA) is a rare benign polypoid tumor arising in the uterine endometrium which was first designated by Mazur in 1981. Microscopic examination reveals architecturally and cytologically atypical endometrial glands separated by intersecting fascicles of smooth muscle cells. The tumor can be misdiagnosed as endometrial adenocarcinoma with myometrial invasion, especially on microscopic examination of a curettage specimen. However a granulation tissue-like stromal response is absent and the smooth muscle in APA is more cellular than that of normal myometrium. We are reporting 2 cases of APA of the uterine endometrium which are 1.5 cm and 1.7 cm in size, respectively, in a 30 and a 22 year-old women. This is the first report in Korean literature using the immunohistochemical staining for smooth muscle actin and desmin.

An ABO discrepancy was observed in a 19-year-old man clinically diagnosed as congenital hypogammaglobulinemia. The patient's red cell was typed as group O, and his serum had no ABO isoagglutinins. Absence of A antigen and B antigen on patient's RBC was confirmed by adsorption- elution test and saliva test. A-transferase and B-transferase activities were not demonstrated in patient's serum. Patient's serum protein electrophoresis revealed hypogammaglobulinemia pattern, and immunoglobulin levels were markedly decreased. Complete absence of B lymphocytes was observed on patient's lymphocyte subset profile. Patient's father and mother were typed as blood group O and no abnormalities were recognized in their serum protein electrophoresis patterns and immunoglobulin concentration.

Changes in contrast sensitivity have been demonstrated in patients with normal Snellen acuity. In an attempt to elucidate more sensitively the visual dysfunction before developement of either overt retinopathy or a reduction in Snellen acuity in patients with retinal disorders, contrast sensitivity test was performed in diabetic patients with normal Snellen acuity and control subjects matched for age and sex. The results were as follows. 1) Throughout all spatial frequencies(1.5 - 3.0 - 6.0 - 12.0 - 18.0 cpd), contrast sensitivity was significantly lower(P-value<0.01) in the diabetic eyes with retinopathy(30.7 - 49.3 - 52.5 - 16.1 - 7.8) than in the normal controls(42.5 - 84.3 - 103.0 - 60.5 - 25.1) or the diabetic eyes without retinopathy(43.1 - 92.2 - 95.8 - 43.4 - 16.4 ). 2) In high spatial frequencies(12.0 - 18.0 cpd) contrast sensitivity in the diabetic eyes without retinopathy group(43.4 - 16.4) was significantly decreased(P-value<0.01) in comparison with the normal controls(60.5 - 25.1). So, contrast sensitivity test is more sensitive test for central visual function than Snellen acuity.

Patellofemoral joint problems refer to a spectrum of conditions affecting the patellofemoral joint, which is the joint between the patella and femur. These conditions can cause pain and instability in the knee and affect an individual’s ability to perform daily activities. Patellofemoral joint problems commonly cause knee pain, particularly among young athletes and physically active individuals. This review article discusses current patellofemoral joint problems, including their epidemiology, pathophysiology, diagnosis, and management.Current Concepts: Patellofemoral joint problems are presented as clinical symptoms of pain and instability. Dividing the diagnostic criteria into anterior knee pain, patella instability, and patellofemoral arthritis is useful. Anterior knee pain is diagnosed after excluding possible causes. Patellar instability is classified into recurrent dislocation, habitual dislocation (extension and flexion types), and permanent dislocation. Moreover, patellar instability can progress to the final stage of patellofemoral arthritis. Thus, patellar instability should be treated according to the Dejour criterion, and patellofemoral arthritis treatment requires artificial joint replacement surgery.Discussion and Conclusion: The pathological mechanism of patellofemoral joint problems still needs to be properly established, and multifactorial causes make it difficult to treat patellofemoral joint problems. Accurate diagnosis is considered an essential factor for successful treatment.
