The purpose of this study was to evaluate the bone age and hand anomaly in Down syndrome patients. We reviewed radiographs in 52 children and youths with Down syndrome, aged from 2 to 23 years. The characteristic findings of hand anomaly were observed in the middle phalanx of the fifth finger, with the following incidence; brachymesophalangia (44%), clinodactyly (48%), and dysmesophalangia (15%). Pseudoepiphysis (21%) was found typically at the distal end of the first metacarpal bone and proximal end of the second metacarpal bone. Up to 8.5 years of age, bone maturation was retarded and thereafter bone age accelarated in advance of chronologic age. These findings may provide valuable information relative to the diagnosis and treatment of hand anomaly in Down syndrome.

Lymphangioleiomyomatosis(LAM) is a rare disease of women of child-bearing age in which there is progressive hyperplasia of atypical smooth mucle along lymphatics in the lung, and/or axial lymphatics in the thorax and abdomen, resulting in honeycombing of lung. Interestingly there has been a speculation that it represents a forme furste or incomplete expression of tuberous sclerosis complex. This is based on the observation that patients with tuberous sclerosis can manifest pulmonary lesions indistinguishable from LAM. We report a case of LAM occuring in a 39-year-old female, who complained of recurrent pneumothorax, chest pain and shortness of breath. Three years ago, the patient had right nephrectomy under the diagnosis of ruptured angiomyolipoma. A X-ray film of the chest showed honeycombing with a diffusely reticulonodular pattern and cyst-like spaces. She had a characteristic facial appearance of adenoma sebaceum, which her father and uncle had. Microscopically, the lung showed a marked smooth muscle proliferation around the slit-like lymphatic spaces and also some respiratory bronchioles.

Objective: To examine the effects of Tribulus terrestris L. (T. terrestris) extract on the modulation of calcium channels to evaluate its use in topical agents for treatment of atopic dermatitis. Methods: The 70% methanol extract of T. terrestris was prepared. Human HEK293T cells with over-expressed calcium release-activated calcium channel protein 1 (Orai1), transient receptor potential vanilloid 1, or transient receptor potential vanilloid 3 (TRPV3) were treated with T. terrestris extract. Modulation of ion channels was measured using a conventional whole-cell patch-clamp technique. Results: T. terrestris extract (100 mg/mL) significantly inhibited Orai1 activity in Orai1-stromal interaction molecule 1 co-overexpressed HEK293T cells. In addition, T. terrestris extract significantly increased the TRPV3 activity compared with 2-Aminoethyl diphe-nylborinate (100 mmol/L), which induces the full activation of TRPV3. Conclusions: Our results suggest that T. terrestris extract may have a therapeutic po-tential for recovery of abnormal skin barrier pathologies in atopic dermatitis through modulating the activities of calcium ion channels, Orai1 and TRPV3. This is the first study to report the modulatory effect of a medicinal plant on the function of ion channels in skin barrier.

PURPOSE: To determine whether the compression technique is a valuable additional method for differentiating between benign and malignant breast masses. MATERIALS AND METHODS: The ultrasonographic findings of 95 benign and 53 malignant masses, all pathologically proven, were prospectively analyzed with regard to five diagnostic criteria: shape (regular/irregular), retrotumoral acoustic phenomena (posterior enhancement/posterior attenuation), internal echo pattern (homogeneous/inhomogeneous), compression effect on shape (distortion/no change), and compression effect on internal echo pattern (more homogeneous/no change). RESULTS: The number of cases of benign and malignant masses, respectively, was as follows: regular / irregular shape: 84/11, 9/44; posterior acoustic enhancement/posterior attenuation: 82/13, 16/37; homogeneous/inhomogeneous internal echo pattern: 78/17, 14/39; distortion/no change in shpae: 76/19, 5/48; and more homogeneous/ no change in internal echo pattern: 71/24, 3/50. For all diagnostic criteria for the differentiation of benign and malignant masses, the differences were statistically significant (p<.05). CONCLUSION: Ultrasonography is helpful for differentiating between benign and malignant breast masses. The compression technique is a valuable additional diagnostic method.

Primary germ cell tumor of the testis is rare, which occupies 1 to 2% of all reported malignant male neoplasms. Combined primary germ cell tumor of the testis composed of embryonal carcinoma and seminoma is more rare tumor. The authors experienced a case of 50-year old male who presented with painless enlargement of right testicle. He has had radical orchiectomy and diagnosed by pathologically as combined germ cell tumor of testis. The testicle is measuring 180 gm in weight and 9×6×5 cm in dimension, and almostly replaced by tumor mass. Grossly the tumor is rubbery solid smooth tumor mass, with variegated cut surface with geographically outlined diffuse necrotic area. Histologically the tumor is composed of two components of tumor, which are solid growth pattern of large round to polyhedral cells with clear or granular cytoplasm and distinct cell border, and anastomosing glandular and papillary arrangement of anaplastic epithelial cells. The former corresponds to seminoma, and the latter to embryonal carcinoma. Each tumor lobule is separated by abundant fibrous stroma.

A clinical observation was made on 13 cases of pediatric urolithiasis admitted to the Department of Urology. Han Il Hospital during the period from Jan., 1971 to Dec., 1975, and the following results were obtained. 1) Among 78 cases of pediatric in-patient, 13 cases were pediatric urolithiasis, 10 cases were male and 3 cases were female. 2) Age distribution was between 2 and 13 years, showing the highest incidence in 7yrs (23.0%). 3) The etiology of urinary tract stone: 2 cases in congenital anomaly, 8 cases in idiopathic, 1 case in foreign body, 1 case in immobilization, 1 case in recurrent infection. 4) Locational distribution of urinary tract stone was 5 cases in ureter, 4 cases in bladder, 3 cases in urethra, 2 cases in kidney. 5) The largest stone extracted was 2.0cm in size. 6) The common clinical manifestation of upper urinary tract stone included flank pain (71.4). hematuria (57. 1%) and lower urinary tract stone included painful urination (85. 7%), frequent urination (71.4%). 7) The most frequent method of treatment was lithotomy(57%). 8) The results of chemical analysis of 9 urinary calculi showed ca. oxalate in 33.3%, cal. Phosphate + oxalate in 33.3%.
