STATEMENT OF PROBLEM: Within the elastic limit of the screw, the greater the preload, the tighter and more secure the screw joint. However, additional tensile forces can incur plastic deformation of the abutment screw when functional loads are superimposed on preload stresses, and they can elicit the loosening or fracture of the abutment screw. Therefore, it is necessary to find the optimum preload that will maximize fatigue life and simultaneously offer a reasonable degree of protection against loosening. Another critical factor in addition to the applied torque which can affect the amount of preload is the joint connection type between implant and abutment. PURPOSE: The purpose of this study was to evaluate the influence of tightening torque on the implant-abutment screw joint stability. MATERIAL AND METHODS: Respectively, three different amount of tightening torque (20, 30, and 40 Ncm) were applied to implant systems with three different joint connections, one external butt joint and two internal cones. The initial removal torque value and the postload (cyclic loading up to 100,000 cycles) removal torque value of the abutment screw were measured with digital torque gauge. Then rate of the initial and the postload removal torque loss were calculated for the comparison of the effect of tightening torques and joint connection types between implant and abutment on the joint stability. Results and CONCLUSION: 1. Increase in tightening torque value resulted in significant increase in initial and postload removal torque value in all implant systems (P < .05). 2. Initial removal torque loss rates in SS II system were not significantly different when three different tightening torque values were applied (P > .05), however GS II and US II systems exhibited significantly lower loss rates with 40 Ncm torque value than with 20 Ncm (P < .05). 3. In all implant systems, postload removal torque loss rates were lowest when the torque value of 30 Ncm was applied (P < .05). 4. Postload removal torque loss rates tended to increase in order of SS II, GS II and US II system. 5. There was no correlation between initial removal torque value and postload removal torque loss rate (P > .05).

Disseminated Fusarium infection has rarely been encountered in neutropenic cancer patients. The clinical features include fever, positive blood cultures, severe myalgias, disseminated ecthyma gangrenosum-like skin lesions, ocular symptoms and multi-organ-system involvement. The mortality rate reported so far exceeded 70% despite antifungal treatments. We report here the first two cases of disseminated fusarial infections in Korea. The first patient contracted pneumonia during severe neutropenic period following consolidation chemotherapy for acute myelogenous leukemia(AML). Fusarium oxyshrum was cultured from bronchoalveolar lavage fluid. The patient remains free of fungemia after successful antifungal treatment of high-dose amphotericin B and terbinafine. The second patient had relapsed AML and suffered from disseminated fusarial infection involving lungs with characteristic skin lesions. The patient succumbed to refractory leukemia and the fungal infection. A brief review of the literature ensues with the case report.

Plasma cell balanitis (Balanitis circumscripta plasmacellularis or Zoon's balanitis) is an idiopathic, benign condition of the glans penis or prepuce. It occurs mostly as a solitary, persistent plaque among middle-aged to older uncircumcised males. It is characterized by chronic, shiny, smooth, red-orange plaques with small, dark red stippling. When the plasma cell balanitis is suspected clinically, diagnosis can be readily confirmed by microscopic examinations of the lesion. Differentiating this lesion from similar lesions such as premalignant, infective and other inflammatory penile lesions is important. The current preferred treatment is circumcision and this disorder can be treated relatively easily by circumcision. We, herein, report an interesting case of plasma cell balanitis on preputial mucosa.

Keratosis follicularis squamosa (Dohi) is a keratinizing disorder which is a separate clinical entity from keratosis follicularis (Darier's disease). It occurs predominantly in Japanese and appears clinically as scaly patches of 3~10 mm in diameter with brownish follicular plugs in the center, which are symmetrically scattered on the trunks and thighs. Scales on the margin, slightly detached from the underlying epidermis, look like 'lotus leaves on the water'. The efficacy of minocycline has already been confirmed in many cases. In this report, we describe a case of using 1% of pimecrolimus cream for keratosis follicularis squamosa (Dohi) instead of minocycline.

OBJECTIVES: The purpose of this study was to investigate the prevalence of sleep problems in Korean elementary school children and the differences in sleep problems related to their school grade and gender. METHODS: One public elementary school in Dae-gu, Korea was randomly selected. And, parents who agreed to participate this study were asked to complete a modified version of Tucson Children's Assessment of Sleep Apnea screening questionnaire (TuCASA). RESULTS: The most common sleep problem was 'falling asleep in a vehicle (44.2%)' and the prevalence rate of this problem differed by school grade. The prevalence rate of falling asleep while watching TV before 8 P.M. (8.0%), daytime fatigue (21.9%) and nocturnal enuresis during the past 6 months (5.3%) were significantly differed by school grade. The prevalence rate of falling asleep while doing home work, falling asleep during a lesson, snoring and bruxism were 12.6%, 1.0%, 26.7% and 13.2% respectively. Although these rates did not show any differences between grades, snoring was more in boys and daytime fatigue was more in girls.. CONCLUSION: This study demonstrates that many elementary school children may have various sleep problems. Lower grade elementary schoolers had sleep problems which related to neuro-developmental factors, whereas higher grade elementary schoolers had sleep problems related to sleep deprivation and stress. Finally, more female schooler showed signs of fatigue or sleepiness than male schoolers.

Green nail syndrome (chromonychia) is a nail disorder characterized by onycholysis and green-black discoloration of the nail bed. This condition is often associated with chronic paronychia. Pseudomonas aeruginosa is the most commonly identified organism in cultures from the affected area. Despite the various treatment options available, removal of the nail is still necessary in many cases. A 35-year-old man presented with dark-greenish discoloration of the nail plate and onycholysis on the left thumbnail. He had been treated with oral antifungal and antibiotic agents for several months; however, the lesion showed no improvement. The diagnosis of green nail syndrome was established after a positive bacterial culture, and on the basis of the antibiotic sensitivity test result, tobramycin eye drop (Tobrex(R)) was then prescribed. Three weeks later, the nail discoloration almost vanished but the onycholysis remained. Herein, we recommend the application of tobramycin eye drop as an easy and safe treatment option for green nail syndrome.

Miller-Fisher syndrome is an acute poly-neuropathy typically characterized by the triad of ophthalmoplegia, ataxia, and areflexia. Other poly-neuropathy diseases include Guillain-Barre syndrome and Bickerstaff brainstem encephalitis. However, not all cases of Miller-Fisher syndrome have the typical three symptoms. These diseases have been differentiated by clinical manifestations and anti-GQ1b IgG antibody testing. In Miller-Fisher syndrome, anti-GQ1b IgG antibody is present in over 95% of patients; however, the frequency is not so high in normal subjects or in those with other poly-neuropathy diseases. Infectious illnesses, such as respiratory diseases and gastrointestinal diseases, usually precede Miller-Fisher syndrome. In general, Miller-Fisher syndrome is a self-limiting illness; however, a few cases of Miller-Fisher syndrome progressing to respiratory failure have been reported, particularly in children. In this case, we report abnormal angiographic findings. We report a case of atypical Miller-Fisher syndrome with internal carotid artery stenosis treated with prednisolone.

PURPOSE: Hypertrophic scars after burn wound management remain a difficult problem for many burn surgeons despite of new treatment option is developed. After burn wound healed with scarring or pigmentation, the patient suffer in daily life with the cosmetic results and scar symptoms. Dermastamp(R) is new treatment modality on burn scar management in our burn center. Dermastamp(R) is stamp shaped and it contains 0.8 mm or 2.1 mm long multiple stainless steel needles. Dermastamp(R) was simply pressed down on the scar 3~4 times and makes 200~300 holes on 1 cm2 scar area. Dermastamping breaks the dense collagen fiber and fibroblast in the scar tissue and rearranges collagen fiber and fibroblast in the scar tissue. METHODS: The 51 patients were selected. The group consisted of 26 male and 25 female patients. 21 patients were adult and 30 patients were children. Stamping area of the 18 patients was below 25 cm2, 6 patients were in 25 to 100 cm2, and 27 patients were above 100 cm2, stamping area. They received Dermastamp(R) treatment 3 to 23 times in every 1 or 2 weeks interval at least 2 months. The 33 patients received Dermastamp(R) under local anesthesia and other 18 patients received under volatile induction anesthesia. Hypertrophic scar is evaluated with Vancouber Scar Scale (VSS) score by two surgeons and scar height using Sonography (17 patients). And pathologic study (17 patients) was done on volunteer cases. RESULTS: Clinically improvements with VSS score (1 to 6 points down) were noted in all patients group. Scar height was lowered (0.8 to 3.6 mm) on sonography and pathologic report revealed collagen fiber rearrangement and scar height thinning in examined group. CONCLUSION: Microneedling procedure is a effective modality of management on hypertrophic scarring and pigmentation. Microneedling induces collagen fiber rearrangement on scar tissue and thinner the scar height in pathology and improves clinical evaluating with VSS score and patients symptoms.
