We report a case of trichorrhexis nodosa in 16-year-old male. Multiple broken hair patches were seen on the both eyebrows. Scanning electron micrascopic findings revealed typical trichorrhexis nodosa; nodular swelling of hair shaft, loss of hair cuticle, longitudinal fissuring and fracture of hair cortex, and paintbrush effect on the side of fracture. Simple avoidance of trauma gave some regrowth of hair. Intralesinional administration of triamcinolone acetonide was not to be effective.

BACKGROUND/AIMS: The caudal anesthsia is most commonly used for benign anorectal surgery, The combination of long-acting anesthetics and opiates has been used for longer duration and successful control of postoperative pain. But the side effects of peridural anesthesics and morphine have commonly occured in caudal anesthesia. This study was performed to assess the difference in clinical effects between peridural mepivacaine and bupivacaine with morphine. METHODS: We evaluated the clinical effects in 60 patients who had anal operation with Jack-Knife position under caudal anesthesia. We divided randomly these 60 patients into two groups, M and B groups (in each group, 30 patients included). Group M (n=30) was given 2% mepivacaine 20 ml with morphine 2 mg caudally, and Group B (n=30) was given 0.5% bupivacaine 20 ml with morphine 2 mg in the same manner. We measured the onset time, duration, postoperative analgesia, and side effects including urinary retention. RESULTS: The onset time for analgesia was significantly shorter in group M than in group B. The duration of postoperative pain complaints was significantly longer in group M than in group B. The postoperative analgesic effects and side effects were not significantly different between two groups. CONCLUSIONS: Caudal mepivacaine and morphine mixture is effective for control of postoperative pain without significant side effects.

We present a case of transient acantholytic dermatosis which developed on the face of a 19-year-old Korean girl. Asyrnptomatic pinhead to miliary-grain sized brownish papules arranged in a somewhat band-like outbreak along the left side of the nose for about 3 months. Histopathologic findings were similar to Dariers disease. Immunoperoxidase staining showed that IgG was deposited on the intercellular area of keratinocytes around the suprabasal clefts. Skin lesions disappeared spontaneously in 5 weeks after a skin biopsy.

To evaluate whether mast cells are involved in developing pathologic feature of psoriasis, 60 biopsy specimens of patients with psoriasis were analyzed. They had not been treated for at least 1 week before skin biopsy. Histological findings in early and fully developed lesions and numbers of mast cells in their dermal papillae were investigated. The results were as follows: 1. In epidermal changes of psoriatic lesions, parakeratosis and acanthosis revealed different findings between early lesions and fully developed lesions. While early lesions revealed mounds of parakeratosis and mild to moderate acanthosis, fully developed lesions revealed confluent parakeratosis and moderate to severe acanthosis. In dermal changes of psoriatic lesions, papillomatosis revealed different findings between early developed lesions and fully developed lesions. While early lesions revealed normal to moderate papillomatosis, fully developed lesions revealed moderate to severe papillomatosis. 2. Degree of acanthosis is related to the degree of papillomatosis. The more increase in the degree of acanthosis, papillomatosis, and parakeratosis, mast cell numbers in dermal papillae were more increased. 3. Mast cell numbers in dermal papillae were more increased in fully developed lesions than early lesions. 4. These findings suggest that mast cell may play an active role in developing pathologic finding of psoriasis.

Antiseptics are substances that kill or prevent the growth of microorganisms when applied to living tissue. They must be effective against microorganisms but must also retain their activity in presence of body fluids without being harmful locally or systemically. Among many antiseptics, Betadine(R) has been widely used because of its low toxicity and high germicidal efficacy. We reported 2 cases of allergic contact dermatitis to Betadine(R) in surgical patients. They had eczematous eruption along the Betadine(R) applying sites. Path tests Betadine(R) confirmed the diagnosis.

INTRODUCTION: The fixation strength of transpedicular screw system in the vertebral hody relied on bone quality and anatomical characteristics of vertebral pedicle, designs of screw and types of connection(rod or plate) with screw. The purpose of this study is to verify the biomechanical nature of the transpedicular fixation in spine under various conditions with porcine vertebrae. MATERIAL AND METHOD: Fresh porcine vertebrae and the custom-made screws were used in this experiment. To reduce the errors caused by vertebral bodies of different size and quality, vertebral bodies having regular range of pedicular width(10.0 to 11.5mm) and hone density(more than 1.0 gm/cm2) were used. The pedicle screws were inserted in the same procedure and axial pull out test was performed with using the Material Testing System(lntron8511, Canton, USA). The experiments were performed in four types to assess the difference of strength accroding to designs of the screw hy using two group of screws. The first group of screw was designed according to the outer and inner diameter and the second group was designed according to the shape, pitch, and thread profile of screw. Experiment I was perfomed to evaluate the effect of screw diameters on the biomechanical pull-out strength hy using the first group of custom-made pedicle screw which fixed all other factors except the diameter of screw. Experiment I was to verify the effect of screw shape, experiment III to verify the effect of pitch and experiment IV to verify the effect of thread profile. RESULTS: The results of experiments were summarized as follows: Experiment I showed that the screw of larger outer diameter had greater holding strength. Experiment II showed that the holding strength of cylindrical shaped screw is superior to that of conical shaped screw. Experiment III showed that there is no statistical significance between different modes of pitch. Experiment IV showed that the holding strength of buttress shape of thread profile is superior to that of V-shape. CONCLUSION: It seemed that the fixation strength of the screw was more powerful with 1 mm increment of outer diameter in 4-7mm of outer diameter, 3mm of pitch and buttress shape of thread of the screw with the same operation technique.

Early diagnosis of persistent abnormal reflexes may be of great significance to a more effective functioning of the cerebral palsied child. It is important to know the normal and abnormal reflex responses and their effect upon motor development for providing a basis for evaluation in the diagnosis and treatment of the cerebral palsied child. We studied 28 cerebral palsied children, between 1 to 12 years old, who were treated at Sam Yook Childrens Rehabilitation Center from May 1975 to December 1977. The pathologic reflexes were checked, and the relationship between pathologic reflexes and walking was compared. The following results were obtained. 1. The following were the most important pathologic reflexes in non-walking fgroup: a. Positive supporting reaction b. Protective extensor thrust c. Moro reflex 2. If they are present, the prognosis for walking ambulation was bad and surgery will not improve for the chances of walking.

We report a case of eccrine adenocarcinoma in 65-year-old man who showed tender, painful, dark-brown colored, and verrucous surfaced tumor on the left neck for 18 months. Hisopathologic examination revealed large atypical cell masses with a tubular cystic, or adenoid pattern in the demis and it was difficult to differentiate from metastatic adenocarcinoma. Materials in the lumina revealed PAS positive, diastase resistant, alcian blue positive at pH 2.5 but negative at pH 0,4 Electron microscopy revealed that tumor cells contained secretory vacuoloes and microvilli projected into intercellular space. Around the cells, myoepithelial cell was seen. After radiotherapy and chemotherapy, tumor size was reduced transiently but 2 months later, tumor was more spread.

In vivo 31P NMR spectroscopic study of forearm wrist flexor muscles was performed in two groups of volunteers composed respectively of 6 sedentaries and 6 canoe athletes. A continuous isometric contraction of endurance exercises was adopted in oder to assess the endurance capacity and recovery potential of skeletal muscles. Differences in high energy phosphorus metabolism between the sedentaries and athletes were evaluated with and emphasis on the intracellular pH and Pi/PCr ratio as indicators of high energy phosphorus metabolism. There were no differences of baseline pH and Pi/PCr ratio between the two groups. The athletes sustained the exercise at more acidic intracellular pH and at a higher Pi/PCr ratio of intracellular conditions for an all-out than did the sedentaries. The recovery rate of pH showed no difference between the two groups. There was a tendency of faster recovery of Pi/PCr in athletes showing half recovery time(T1/2) of 39.0±3.0 seconds as compared to that of sedentaries (55.7±7.5 seconds). The recovery rate of Pi/PCr as a function of Pi/PCr ratio at a given period of time was significantly faster in athletes than in sedentaries (P<0.001). The correlation coefficient of the recovery rate of Pi/PCr against the Pi/PCr ratio was 0.985 and 0.914 respectively for the athletes and sedentaries. The pH and the Pi/PCR ratio at an all-out state can be used as indicators of endurance capacity and the recovery rate of Pi/PCr, as a reovery potential of skeletal muscles.
