Occult syringoma means a clinically inapparent tumor of the swea gland that are histologically similar but not identical with the common syringoma. They may occur in a variety of inflammatory skin lesions and cutaneous neoplaams as a reactive process. We report herein a case of diffuse alopecia areata associated with occult syringoma in the scalp of a 57-year-old man. Our patient developed progressive, fairly well circ amscribed patches of alopecia and diffuse hair loss over a 1 month period. Histopathological examinaiion revealed non-scaring alopecia and a proliferation of eccrine ductal structures in the upper dermis. These ductal structures resembled syringoma. Only minimal focal fibrosis was occasionally observed arcund the hair follicles. We believe that occult syringona is a reactive process and is secondary to active inflarnmation or dermal fibrosis. It has been most commonly observed in scarring alobiecias but plays no significant role in the etiology of hair loss.

A 24-year-old man with tuberculosis meningitis developed acute paraplegia and sensory disturbances 5 weeks after receiving conventional antituberculous therapy. Magnetic resonance imaging revealed an intradural extramedullary long segmental mass mimicking en plaque meningioma at the T2-T6 vertebrae levels. Prompt surgical decompression was performed. A histology examination of the mass revealed a tuberculoma. After surgery, the patient showed improved motor power and a normal bladder function. Intradural extramedullary tuberculoma of the spinal cord is rare complication of tuberculosis meningitis, which can occur as a response to conventional antituberculous therapy.

BACKGROUND: The nevus of Ota is a benign dermal melanocytic lesion that was previously proved difficult to treat. Recently, the Q-switched ruby laser and Q-switched Nd: YAG laser have been reported to by, successful in the treatment of benign pigmented lesions and tattos. OBJECTIVE: Our study evaluates the treatment of 60 patients with nevus of Ota with Q-switched Nd: YAG lase (l064nm). METHOD: Sixty patients with nevus of Ota were treated by the Q-switched Nd: YAG laser with pulse width 10nsec, and energy fluences ranging from 5.8 to 12J/cm and the laser repetition rate was 5 or 10Hz. The response to treatment was assessed by four independent investigators with photographs. RESULTS: 1. Total therapeutic effects of Q-switched Nd: YAG laser showed excellent result in 23.3%, good in 45%, fair in 18,3%, and poor in 13.3%. 2. Therapeutic effects by distribution proposed by Tanino showed excellent or good results in 84.6% at type Ia, 78.6% at, type Ib, 66.7% at type II, 60% at type III and 45.5% at type N. 3. Therapeutic effects by the number of treatments showed excellent or good results in 22.2% of patients after one treatment, 72.7% after two treatments, 93.3% after three treatments and 100% after four treatment. 4. Therapeutic effects by energy showed excellent or good results in 9.2% at energy range of 10 to 12J/arl and 66.6%, at energy range of 5.8-9.5J/cm. 5. Complications included transient hyperpigmentation (6.7% ), secondary bacterial infection (1.7 %), hypopigmentation (1.7%) and atrophic scar (1.7%). However these subsided spontaneously in a year. 6. The recurrence rate was 2.4%. CONCLUSION: The Q-switched Nd: YAG laser is a very effective mode of treatment for nevus of Ota which has provent unresponsive to other therapeutic modalities.

Changes of human pulse rates are influenced by psychological factor as well as systemic disease. Pulse rates tend to increase in the state of fear, pain, anxiety, and excitement. We performed this study for the evaluation of psychological state during the surgical extraction of mandibular impacted 3rd molar. Total 42 patients without systemic compromised condition were selected and pulse rates were checked with pulse oximeter(Nellcor, N-180) during the initial sitting state at dental unit chair, local anesthesia, draping and operation(5-minute interval). Male patients were 22, female 20. Age ranged from 13 to 57, with a mean of 26.9. Operative time(from incision to end of suture) ranged from 4 minutes to 32 minutes, with a mean of 11.1 minutes. The most significant elevation of pulse rates were observed during draping, the next at 10 minutes after incision(P< 0.05). Elevation of pulse rates during the anesthesia was not more than preoperative state and variable(P> 0.05).

A malformation of azygos and hemiazygos system were observed from the cadaver for anatomy practice in College of Medicine, Chungnam National University. The observing results were as followings ; Hemiazygos vein was connected with left superior vena cava and drained into coronary sinus, which engorged enough to fill up with blood about 20cc to 30cc. Communicating pathway from hemiazygos vein to azygos veln wasn't found the diameter of left brachiocephalic vein was very small, about 2mm to 3mm. And, the diameter of left internal jugular vein was smaller than that of right infernal jugular vein. In this case, the azygos and hemiazygos system ceased its development at early embryologic stage(around 7 week embryo) and didn't progress into next stage.
