BACKGROUND: Respiratory depression with high dose of propofol during induction is one of the major complications. We studied the effects of midazolam as premedicant on frequency and duration of apnea and frequency of loss of consciousness in relation to single dose of propofol. METHODS: We selected 194 adult patients who had clear consciousness and no depression of respiration. We allocated patients randomly to control group and midazolam group. In midazolam group, we injected 0.06mg/kg of midazolam intravenously 10min before induction, and in control group, we did nothing. Under mask oxygenation with 100% oxygen, we administered a bolus of propofol (1, 1.5, 2 mg/kg to subgroup 1, 2, 3 respectively) intravenously. The change of respiration and loss of consciousness were observed. RESULTS: The frequency and duration of apnea increased with the dose of propofol in both control and midazolam group. But there were no difference between groups except frequency of apnea with 1.5 mg/kg of propofol. In control group, frequency of loss of consciousness increased with the increasing dose of propofol. But in midazolam group, nearly all the patients was slept without difference by the dose. CONCLUSIONS: Premedication with midazolam reduce the sleeping dose of propofol to induce anesthesia, so the frequency and duration of apnea which is caused by high dose of propofol can be decreased.

Colonoscopy is a commonly performed endoscopic procedure. Although it is generally considered to be safe, serious complications, such as colorectal perforation, can occur. Most colonic perforations are intraperitoneal and cause pneumoperitoneum with acute abdominal pain as the initial symptom. However, extraperitoneal perforations with pneumoretroperitoneum may happen, albeit rarely, with atypical initial symptoms. We report a rare case of rectosigmoid perforation occurring after diagnostic colonoscopy that developed into pneumoretroperitoneum, pneumomediastinum, pneumothorax, and subcutaneous emphysema, with a change in voice and neck swelling as the initial symptoms. The patient was successfully treated with endoscopic closure of the perforation and conservative management.

Sweet's syndrome, or acute febrile neutrophilic dermatosis, is an unusual disease characterized by fever, leukocytosis, and distinctive skin lesions. Common complications include arthralgia, arthritis, conjunctivitis, and iridocyclitis. However, the involvement of the central nervous system in this disease, termed `neuro-Sweet syndrome' is rarely reported. We present a patient with recurrent encephalitis for 15 years, accompanied with neutrophilic dermatosis, and characterized by HLA-B54 and Cw1, with good responsiveness to corticosteroid.

Osmotic myelinolysis syndrome in central nervous system is classified into central pontine myelinolysis(CPM) and extrapontine myelinolysis(EPM). The former can cause a spastic quadriplegia, pseudobulbar palsy, and varying degree of mental disorder, but the latter a movement disorder(tremor, dystonia, parkinsonism, and chorea, etc), behavior change(mood instability, personality change, agitated delirium, and disinhibition, etc), and cognitive dysfunction. Although a few cases of asymptomatic CPM have been reported, asymptomatic EPM were rare. A 67-year-old woman with diabetes mellitus and old cerebral infarction has suffered from the common bile duct stone. She had hyponatremia(Na=126mEq/L) on admission and was corrected rapidly. Incidental findings of her brain MRI showed EPM. We experienced a case of bilateral middle cerebellar peduncle myelinolysis incidentally without neurological presentations and report a rare case of asymptomatic EPM recoverd in diabetic woman after rapid correction of hyponatremia.

Perifolliculitis capitis abscedens et suffodiens is a rare chronic recalcitrant follicular disorder which clinically presents itself as pulstules, nodules, intercommunicating abscess and sinuses that leave atrophic, hypertrophic or keloidal scars. Although the etiology of this of condition is unknown, its association with acne conglobata and hidradenitis suppurativa, collectively termed the follicular occlusion triad, suggest a cammon basic pathogenic mechanism of follicular retention. The therapeutic problem is reflected in the variety of therapies that have been tried with varying degrees of success. We report a case of a 34-year-old man who showed a patch of alopecia on the vertex of his scalp. Clinically, the scalp showed multiple soft fluctuant elevated nodules with nonscarring alopecic patches. We performed a treatment with isotretinoin(13-cis-retinoic acid) during 6 months. The patients clinical appearance was much improved and local recurrence and hair loss have not been observed to date.

Elastofibroma is a rare disease which presents as a slowly-growing, solid, ill-defined fibroelastic mass occuring almost exclusively in elderly women and arising mainly from the connective tissue between the lower part of the scapula and chest wall. Of the 270 cases of elastofibroma which have been reported, 170 cases had developed in Japanese patients. Despite the fact that there have been only two case reports in Korea, there might be a higher prevalence of elastofibroma in Korea than expected because of geographical similarity. We experienced a case of elastofibroma occurring in a 56-year-old man. To our knowledge, this is the first case report of elastofibroma in Korean dermatologic of literature.
