  • Sleep problems occur frequently among patients with Prader-Willi syndrome (PWS). The most common problem is excessive daytime sleepiness (EDS) that are closely related to of sleep-related breathing disorder (SRBD) such as obstructive sleep apnea (OSA) and congenital hypoventilation syndrome. Obesity, craniofacial dysmorphism and muscular hypotonia of patients with PWS may increase the risk of SRBD. Sleep apneas can interrupt the continuity of sleep, and these disruptions result in a decrease in both the quality and quantity of sleep. In addition to SRBD, other sleep disorders have been reported, such as hypersomnia, a primary abnormality of the rapid eye movement (REM) sleep and narcolepsy traits at sleep onset REM sleep. Patients with PWS have intrinsic abnormalities of sleep-wake cycles due to hypothalamic dysfunction. The treatment of EDS and other sleep disorders in PWS are similar to standard treatments. Correction of sleep hygiene such as sufficient amount of sleep, maintenance of regular sleep-wake rhythm, and planned naps are important. After comprehensive evaluation of sleep disturbances, CPAP or surgery should be recommended for treatment of SRBD. Remaining EDS or narcolepsy-like syndrome are controlled by stimulant medication. Bright light therapy might be beneficial for disturbed circadian sleep-wake rhythm caused by hypothalamic dysfunction.

  • A 4-year-old female American cocker spaniel was hospitalized with 6 months prolonged dermal problems in The Veterinary Medical Teaching Hospital of Seoul National University. Initial noticed signs by owner of this dog were rashes and papules on ear part and they were spreaded whole body. On initial physical examinations, papules, pustules, crusts, and erythema were presented on whole body. Diameters of focal scaly and erythematous alopetic lesions were varied ranging 1 to 4cm. Skin scraping for detecting ectoparasites and wood's light examinations for dermatophyte were negative. Any bacteria were not detected but Malassezia pachydermatis was detected on cytological examination and fungal culture. The dog was treated with Itraconazole (5mg/kg, q12h) and Cephalexin (20mg/kg, q12h) orally and then bathed with 2% chlorhexidine shampoo twice per week for 5 weeks. From 12 weeks after starting therapy, all dermal problems were disappeared although some mild pyoderma were once relapsed. Regular chlorhexidine bathing treatment so far has been continued for preventing recurrence.

  • Premenstural dysphoric disorder(PMDD) imposing 4-5% of women is possibly caused by an enhanced responsiveness to the changes of sex steroid hormones and the decrease of serotonin, melatonin and GABA. The common clinical features between PMDD and depression, seasonal affective disorder, panic disorder and anorexia nervosa suggest a relatedness between PMDD and each of them. The diagnostic criteria of DSM-IV-Tr for PMDD requires psychological symptoms, that commonly include irritability, anger, depression, mood swing, affect lability, tension, anxiety, fatigue and food craving. As of today, the best pharmacological treatment for PMDD is the selective serotonin reuptake inhibiter, and leuprolide, danazol, estradiol, spironolactone and bromocriptine are possible alternatives. Nonpharmacological treatments for patients with mild to moderate symptom severity are diet, exercise, light therapy, psychotherapy and keeping a diary.

  • The Spreading-Qi recorded curative effect with a long history. I studied the Qi-therapy through train of the Qi-sender. methods of the Spreading-Qi and clinical application of the Spreading-Qi. 1. Train of the Qi-sender. Sitting, standing and ling postures can all be applied as training postures for training Qi. Qi grows in Lower Dan(elixir field) and circulates in heavenly circuits by static Qi. Training Qi by dynamic Qi is a fundamental exercise for the maneuvers to conduct Qi. 2. Methods of the Spreading-Qi, Breathe naturally concentrate the mind on Lower Dan(elixir field). When exhaling. Mindwill accompanies Qi to go to the Conception Vessel(CV) and Governor Vessel(GV), conduct Qi to the palms or fingers and emit Qi, with the emitting site touching or leaving the treated region. 3. Clinical application of the Spreading-Qi, its wide range of indications. 4. The Spreading-Qi is similar to Western 'Healing' and 'Hands of light'. Mind will accompanies energy to go to hand and emit energy to the treated region.

  • Purpose: The aim of this study is to compare the effects of bone marrow stromal cells(BSCs) and fibroblasts on wound healing activity in vivo, especially on epithelization. Methods: The fibroblasts and BSCs were harvested from patients and cultured. Ten Spague-Dawley white rats were used. A 5 mm punches were made to excise skin and subcutaneous tissue in a round fashion at six sites on the back area of each rat. Four hundred thousand cells suspended in 0.05 ml fibrinogen were applied to the created wounds. The cells in group I, II, and III were no cells, fibroblasts and BSCs. The lengths of epithelial gap at the widest wound site were compared with autopsy specimens obtained on the 6th day after cell therapy under light microscope. Statistical comparisons were performed using the Mann-Whitney U-test, and the p value < 0.05 was considered statistically significant. Results: The best epithelization was also seen in the BSC group, followed by fibroblast and no cell groups.Conclusion: These results demonstrate that BSC has superior effect on stimulating wound healing than fibroblast, which is currently used for wound healing.

  • Tracheal granuloma, the most commonly reported sequela of pediatric tracheotomy. A variety of techniques are available for the management of tracheal granuloma. Potassium-titanyl-phosphate (KTP) laser has been previously established as an acceptable technique for removal of laryngeal surgery, which emits a green light with a wave length of 532 nm, which is well-absorbed by hemoglobin and can coagulate and vaporize tissue. The ability to deliver laser energy through a flexible glass fiber makes the technique convenient for use with a rigid bronchoscope, overcoming problems with intraluminal access encountered with earlier attempts at CO2 laser therapy for this problem. Another advantage of KTP laser is the avoidance of the risks and morbidity associated with an open procedure. We report our surgical technique KTP laser in the management of tracheal granuloma removal into the tracheostomy site. KTP laser is good tool for management of tracheal granuloma with low incidence of complications.
