Humeral head chondrolysis has been widely reported as a devastating complication after arthroscopic shoulder surgery; however little is known about post-arthroscopic humeral head osteonecrosis. We experienced a 66-year-old female patient with rapidly progressive osteonecrosis of the humeral head only seven months after arthroscopic Bankart and rotator cuff repair. The patient had no systemic risk factors for osteonecrosis. A satisfactory result was achieved with reverse total shoulder arthroplasty for severe humeral head destruction and an irreparable massive rotator cuff tear. Shoulder surgeons should be aware of such severe complication, perform routine radiographs, and pay close attention to the presence of constant pain or loss of motion after arthroscopic shoulder surgery.

Four cases of incontinentia pigmenti (Bloch-Sulzberger type) in a mother and three her daughter were presented and literatures were reviewed. In all three daughters vesicles appeared on toes at three weeks after birth and ehanged to pigmented patches surrounded by erythematous verrucous margin, which were then gradually spread to whole body. Pigmentation is dirty, irregular and bizarr. Severe itching sensation was complained and vesicles or bulla were formed easily due to scratching and external trauma. In mother, onset of the disease was not clear but generalized dirty pigmentation is showed. Dentition was delayed in 3rd daughter (Dental eruption was begun at 10 month old and 11 teeth was showed at now, 2 year old). Histopathological findings are compatible with incontinentia pigmenti and epidermo-dermaI separation is observed in a experimentally induced bullae, indicating a characterized epidermolysis bullosa. Strict limitation in the occurence of disease in females of one family, accompanying with epidermolysis bullosa simplex is unusual and interesting in genetical aspects and pathogenesis.

PURPOSE: To demonstrate and evaluate the value of MRI findings of the TSH(Thyroid-Stimulating Hormone, TSH, Thyrotropin)-secreting pituitary adenoma. MATERIALS AND METHODS: The authors reviewed retrospectively the MR images of 4 patients with TSH-secreting pituiatary adenoma. Evaluation of the anatomical location, signal characteristics, enhancement patterns, size, shape and circunferential changes were made. RESULTS: No characteristic common MR findings in size, shape, signal intensity, and circumferential changes of TSH-secreting pituiatary adenoma waere observed among 4 cases(size; 5x7 mm to 10x11 mm, shape;ovoid to round, signal intensity;high in 1 case on T1 and T2WI, isosignal intensity in the other 3 cases, circumferential change; stalk deviation in 1 case, no stalk deviation in 3 cases). But, the tumors were centrally located at the anterior pituitary gland and showed relatively homogeneous signal intensity on MR images of all 4 patients. CONCLUSION: We conclude that centrally-located mass at the anterior pituitary gland with homogeneous signal intensity on MR image may be suggestive of the TSH-secreting pituitary adenoma, although the MR findings are not specific for the disease.

The aim of this study was to investigate the effect of third molar extraction on the periodontal status of the adjacent second molar. A total of 61 second molars in 31 adult periodontitis patients were examined. Among them, 27 second molars without adjacent third molars were included in the test group, and 34 second molars with third molar were included in the control group. Clinical parameters including plaque index, gingival index, and pocket depth and radiographic bone loss were measured around the second molar both in test and control group. The result showed that: (1) the mean plaque index and gingival index of control group were higher than these of the test group but the difference was not statistically significant, (2) the mean pocket depth of the control group was higher than the test group significantly at distal and buccal surface, (3) radiographic bone loss was greater in control group than test group significantly, (4) in Pearson correlation analysis between the age of extraction and radiographic bone loss in the test group, a positive relationship was shown(p<0.01). Within limitation of this study, it may be concluded that third molar extraction in periodontitis patients showed an improvement in periodontal status in contrast the patients group having third molar, therefore earlier a removal of third molar may minimize radiographic bone loss of the adjacent second molar.

To elucidate the effects of food texture such as hardness, cohesiveness, adhesiveness on mastication procedure, the electromyographic activity (EMG) of the masticatory muscles and the chewing movements were analyzed in eighteen young subjects during ordinary chewing. Seven different foods were selected by sensory texture profiling and mechanical test with texturometer; egg white, sausage, pizza cheese, yang-geng, biscuit, peanut and almond. The indexes of jaw movements used were the chewing number, chewing time, maximum opening, average opening, closing velocity and opening velocity. The EMG indexes analyzed were maximum and average integrated amplitude of the anterior temporal and masseter muscles. The results obtained were as follows. 1. The chewing time and chewing number, mandibular displacement and mandibular movement velocity were not changed by the hardness, cohesiveness and adhesiveness of the food (p>0.05). 2. The harder food materials showed a higher amplitude of the anterior temporal muscle integrated EMGs than the softer ones (p<0.05). 3. The maximum and average integrated EMGs of the masseter muscle increased with the increase of hardness of the food (p<0.05). 4. The integrated EMGs of preferred side and non-preferred side masticatory muscles increased with the increase of hardness of the food (p<0.05). 5. The adhesiveness and cohesiveness of the food were not the determining factor to the integrated EMGs of masticatory muscles (p<0.05).
