Atypical fibroxanthoma(AFX) occurs most on sun-exposed area of the head and neck of elderly person. It has an excellent prognosis after conservative, but complete, excision. However, because of its potential, albeit small, for metastasis, it is widely regarded as a low-grade sarcoma. We present herein two cases of atypical fibroxanthoma. The case 1 was a 86-year-old female who had a small egg-sized, dome shaped nodule with eroive surface on the left cheek. The other case was a 60-year-old male who had solitry bean-sized, nodulo-ulcerative lesion on the vertex. Immunohistochemical studies revealed positive reaction for vimntin and a-antichymo trypsin. These patients have received completely total surgical ecis on and remained free of recurrence for a period of about, 2 years follow up.

To evaluate the effects of Dexamethasone(Dex), Platelet derived growth factor-BB(PDGF) and combination of Dex and PDGF(DP) on the growth and differentiation of MC3T3-E1 cells, Dex(10(-7) M) and PDGF(10 ng/ml) in experimental group were added to the cells at the days 5, 10, 15, 20, 25 and examined for cell proliferation activities, DNA synthesis activities, ALP activities and bone nodule formation. The results were as follows : 1.In Dex group, cell proliferation, DNA synthesis and ALP activities were lower until 15 days when compared to the control group. Bone nodules formation were shown at 10 days. 2.In PDGF group, cell proliferation and DNA synthesis activities were higher until 15 days and ALP activities were lower when compared to the control and Dex groups. Bone nodules formation were shown at 20 days. 3.In DP group, cell proliferation and DNA synthesis activities of PDGF were suppressed by Dex and synergistic effects of combination of Dex and PDGF on ALP activities were shown at days 5 when compared to control and Dex groups. Bone nodules formation activities of Dex were suppressed by PDGF.

Topical immunotherapy with diphenylcyclopropenone(DPCP) has been used for the treatment of alopecia areata. Due to the therapeutic principle of producing a contact eczema, itching, erythema and scaling are inevitable or even desired side effects. However, erythema multiforme-like reactions following topical DPCP treatment have been rarely reported with an estimated incidence of 1.2%. We present herein a case of Stevens-Johnson syndrome, the severe form of erythema multiforme as a side effect of topical DPCP. A 57-year old male patient visited us for the treatment of alopecia totalis. After sensitization with 0.2% DPCP in acetone, we applied DPCP on the scalp once a week for three weeks. Following the 3rd challenge of DPCP, iris-shaped lesions, erosions, vesicles, and bullae developed with fever. Also, he had vesicles and erosions in the oral cavity. The patient was treated with systemic antibiotics, steroids, and antihistamines. The cutaneous lesions were cleared with hyperpigmentation, and pronounced hair regrowth was observed.

We experienced a case of unilateral vocal cord paralysis following tracheal extubation. The patient was a 60-year-old man undergoing subtotal gastrectomy. He had no laryngeal symptoms prior to operation and the trachea was intubated with a cuffed endotracheal tube. The surgical procedure lasted 6 hours and was uneventful. Three days later after operation, he began to complain of hoarseness and mild aspiration symptom. On endoscopic examination, left vocal cord paralysis was found. Fifteen weeks later the voice and left vocal cord function return to normal without specific management. In this case, we suggested that possible causes of unilateral vocal cord paralysis are compression of recurrent laryngeal nerve by overexpanded endotracheal cuff, laryngeal trauma during difficult intubation, stretching of the nerve as a result of traction on distant organ, decreased elasticity of trachea and surrounding tissues in the older age group and long operating time.

To assess the role of multiple factors in influencing occurrence of ventricular premature complexes after acute myocardial infarction twenty-four hour Holter electrocardiographic tape recording were made in 40 survivors of an acute myocardial infarction 10 to 20days after attack. Ventricular premature complexes in the early post infarction period were not correlated with left ventricular function, age, sex, smoking, diabetes mellitus, previous angina, and previous myocardial infarction. The occurrence of ventricular premature complexes showed a positive correlation with the occurrence of ST-T change. The occurrence of ventricular premature complexes during sleep hours was compared to the awake state. In 22 patients, the incidence of ventricular premature complexes are excluded from analysis, the 22 of patients, or in 76 percent, sleep was associated with a lowered occurrence of ventricular extrasystoles.
