We have reviewed our experiences of computerized tomography(CT) in the fracture of the spine. Between December 1983 and June 1985, we treated 33 fractures of the spine in 32 patients. We have used CT for the diagnosis of fractures of the spine in 29 cases (28 patients). Also we have used Louis scoring system to evaluate the stability of the fractured spine. The results are as follows. 1. CT has many advantages that were not given from simple radiograp hies or laminagrams. It reveals the vertebral body, vertebral column, posterior compartments and surrounding soft tissues excellently, and it is easy to interpretate. Also it can be done comfortably and rapidly without the need of manipulations. 2. We could acquire many informations from post-operative or long term following up of CT examinations. 3. If the Louis score is higher than 3, we should think it is unstable, and should take internal fixation of the vertebral column. 4. There is a correlation between Louis score and neurologic signs (p < 0.01). If there was a neurologic sign with low Louis score, less than 1, the recovery was soon, less than 24 hours. 5. According to CT findings for fragmentation or location of fragment, we can alternate an anterior decompression or a posterior decompression. 6. It is necessary to use CT as a initial diagnostic procedure with the simple radiographic examination in spine fracture.

BACKGROUND: Some of the deficiencies in anterior pituitary function identified in subjects with macroadenomas appear to represent irrevemible necrosis of normal pituitary cells, and in addition reversible damage to viable glandular tissue and/or incomplete interruption of local circulation by compression of pituitary stalk may also contribute significantly to hypopituitarism. So anterior pituitary function may actually improve in some patients undergoing successful tumor resection or reduction in tumor size. Although direct comparisons of pituitary function among the various pituitary tumors are not presently available it was reported that there is some difference in the degree of pituitary impairment between patients with nonfunctioning macroadenoma(NFMA) and those with GH-secreting macroadenoma(GHMA).In this study, to investigate the difference in the degree of hypopituitarism we compared anterior pituitary function in subjects with NFMA to that in patients with GHMA. METHODS: In this retrospective study, preoperative and postoperative anterior pituitary function was assessed by clinical findings, basal hormone levels and/or combined pituitary stimulation test in 29 subjects with NFMA and in 24 subjects with GHMA. RESULTS: 1. There was no difference in age, sex, tumor size distribution between the two groups. 2. Preoperatively, NFMA patients had a higher prevalence of secondary hypothyroidism(34% vs. 5%; p(0.02) compared to subjects with GHMA. Patients with NFMA also had a higher prevalence of more severe pituitary failure compared with acromegalic patients; 48% of the patients in this group had more than one pituitary hormone axis impaired compared to 17% in the acromegalic group(p0.03). 3. Postoperatively, NFMA patients also had a higher prevalence of secondary hypoadrenalism (52% vs. 11%; p 0.01) compared with acromegalic patients. Additionally, the prevalence who had more than one pituitary hormone axis impaired was still greater in NFMA patients than in the acromegalic group(57% vs. 22%; p=0.054). 4. No correlation was found between the severity of pituitary failure and tumor size or extension in both groups before and after surgery. CONCLUSION: These findings suggest that anterior pituitary function is relatively better preserved in patients with GHMA than those with NFMA and that this difference is independent of tumor size and extension. The mechanism underlying the lower rate of hypopituitarism in acromegalics with macroadenoma remains to be elucidated.

We report a case of subcutaneous phaeohyphomycosis caused by Exophiala(E,) jeanselmei in a 66-year-old female, who showed a mild tender, 4.5x3.5cm sized, erythematous cystic mass with satellite lesions on the left forearm for 4 months. Histopathologically, suppurative granulomatous inflammation, brownish conidia in a chain and hyphae were observed. Fungal culture grew out the typical black-gray velvety colonies of E. jeanselmei after 2 weeks. The isolate grow well at 25 C, but very poorly at 37 C. No growth could be observed at 40 C. Sporulation adequate for evaluation was present on the malt extract agar. We confirmed E. jeanselmei by colony and microscopic morphology, temperature tolerance and sugar assimilation tests. The patient had been treated with itraconazole for 6 momths. Complete remission was observed.

4.Proposal of Dual Inhibitor Targeting ATPase Domains of Topoisomerase II and Heat Shock Protein 90.
Biomolecules & Therapeutics 2016;24(5):453-468
There is a conserved ATPase domain in topoisomerase II (topo II) and heat shock protein 90 (Hsp90) which belong to the GHKL (gyrase, Hsp90, histidine kinase, and MutL) family. The inhibitors that target each of topo II and Hsp90 are intensively studied as anti-cancer drugs since they play very important roles in cell proliferation and survival. Therefore the development of dual targeting anti-cancer drugs for topo II and Hsp90 is suggested to be a promising area. The topo II and Hsp90 inhibitors, known to bind to their ATP binding site, were searched. All the inhibitors investigated were docked to both topo II and Hsp90. Four candidate compounds as possible dual inhibitors were selected by analyzing the molecular docking study. The pharmacophore model of dual inhibitors for topo II and Hsp90 were generated and the design of novel dual inhibitor was proposed.

Cosmetic lateral canthoplasty, in which the size of the eye is increased by extending the palpebral fissure and decreasing the degree of the eye slant, has become a prevalent procedure for East Asians. However, it is not uncommon for there to be complications or unfavorable results after the surgery. With this in mind, the authors have designed a surgical method to reduce complications in cosmetic lateral canthoplasty by preserving the lateral canthal angle. We discuss here the anatomy required for surgery, the surgical methods, and methods for reducing complications during cosmetic lateral canthoplasty.

6.Hyposexuality in Men with Obstructive Sleep Apnea Syndrome.
Journal of Sleep Medicine 2015;12(1):7-12
OBJECTIVES: Hyposexuality is defined as diminished sexual drive or libido. There has been little research into the sexuality in patients with obstructive sleep apnea (OSA). We investigated the prevalence and relating factors for hyposexuality in OSA men. METHODS: Consecutive 182 male (mean age 48.3 y) were enrolled who were newly diagnosed with OSA through polysomnography. All completed Symptom checklist-90-Revised (SCL-90-R), Epworth Sleepiness Scale (ESS), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI). Subjects were divided into non-hyposexuality (score 0) and hyposexuality (score > or =1) groups according to the question "Loss of sexual interest or pleasure" in SCL-90-R. RESULTS: 110 of 182 subjects (60.4%) answered hyposexuality (score > or =1). Significant correlations were found between hyposexuality and following factors; age (rho=0.248), BDI (rho=0.450), BAI (rho=0.410), ESS (rho=0.221), and percentage of non-REM stage 3 (N3%) (rho=-0.184). Apnea-hypopnea index was significantly correlated with nocturia (rho=0.320), ESS (r=0.230), N1% (r=0.596), N2% (r=-0.540), N3% (r=-0.195), and lowest oxygen saturation (r=-0.641). Comparing two groups, hyposexuality group showed significantly lowered total sleep time (380.2 min vs. 359.1 min), and sleep efficiency (83% vs. 76%). The severity of hyposexuality was correlated with BDI (rho=0.330), BAI (rho=0.253), and N3% (rho=-0.215) in subjects with hyposexuality. After controlling for age, polysomnographic parameters were not correlated with hyposexuality. CONCLUSIONS: About half of untreated OSA male subjects reported diminished libido. Age, daytime sleepiness, mood disorders, and decreased sleep quality were associated with hyposexuality. Of these, aging process was the most important factor for hyposexuality.

Korean Journal of Dermatology 2023;61(4):226-232
Background:
Oral acitretin (ACT) has been approved for the treatment of psoriasis (PSO), whereas alitretinoin (ALI) has been prescribed off-label. Few studies have compared the efficacy of these two therapeutics.
Objective:
To evaluate the clinical outcomes of oral ACT versus ALI for treating PSO.
Methods:
Sixty-five patients diagnosed with PSO and treated with ACT or ALI were reviewed. Patient demographics, clinical efficacy, and adverse effects were evaluated. Treatment efficacy was assessed using physician’s global assessment (PGA) and psoriasis area and severity index (PASI).
Results:
A total of 38 cases in the ACT group and 27 cases in the ALI group in PSO were retrospectively reviewed. No significant intergroup differences were noted in the proportion of patients achieving PGA score of “clear” or “almost clear” (18.42% vs. 22.22%; p=0.71). The reduction rate of PASI from baseline was higher in the ALI group (24.30% vs. 22.74%; p=0.68), while the rate of achieving 75% improvement in PASI was higher in the ACT group (18.42% vs. 14.81%; p=0.75); no significantly differences were noted. The ALI group had fewer adverse effects (6/27 [22.22%]) than the ACT group (10/38 [26.32%]), and no severe events occurred in either group.
Conclusion
ALI can be considered an off-label treatment option for a limited patient population.

Ex situ resection of the liver is an alternative surgical procedure for patients with conventionally unresectable hepatic tumors, and with contraindications to liver transplantation. We experienced a case of ex situ resection of the liver in a 40-year-old female patient suffering from sclerosing hepatocellular carcinoma. Preoperative liver function was normal. The duration of the anhepatic period was 2 hours and 55 minutes. No severe hemodynamic or pulmonary complications, and no significant metabolic or coagulatory disorders occurred. To obtain good results by ex situ resection of the liver, anesthesiologist should understand the physiology of the anhepatic period and guard against possible problems during the operation.
