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.

PURPOSE: Fungal infections are an important cause of morbidity and mortality in patients with hematologic malignancies. The therapy of choice in documented or suspected invasive fungal infections has been intravenous Amphotericin B (AmB). Adverse effects such as fever, chils, thrombophlebitis, nausea or vomiting are common. A more serious adverse effect is potential renal impairment. As AmB administration mixed with Intralipid (AmB/Intralipid) was reported to decrease AmB toxicity without a concomitant loss of antifungal efficacy, we studied the efficacy and side effects of long-term administration of AmB/Intralipid in leukemic children with invasive fungal diseases. METHODS: AmB/Intralipid was administered in seven leukemic children (male, 3; female, 4) who had invasive fungal infections between July 1994 and March 1997. RESULTS: AmB/Intralipid was administered at a mean concentration of 1.45mg/kg/day for a mean of 58.1 days with cumulative dose of 3.01g. Excluding 2 patients who succumbed to the underlying leukemia, 4 out of 5 remaining patients remained free of both fungal infection and leukemia. Chills associated with AmB/Intralipid were found 13 times in 4 patients. One patient could not continue the administration because of the chills on the 45th day of AmB/Intralipid. Renal and hepatic impairment greater than Grade II toxicity was found in each case, respectively. The other 6 patients showed mild elevation from the baseline, but remained within the normal limits. CONCLUSION: Long-term, high-dose AmB/Intralipid therapy can be safely and effectively used in immunocompromised children with invasive fungal infections.

The aim of this study was to compare the dose distribution of intensity modulated radiation therapy (IMRT) with 3 dimensional conformal radiation therapy (3DCRT) in prostate cancer. The IMRT plan and the 3DCRT plan used the 9 fields technique, respectively. In IMRT, tumor dose was a total dose of 66 Gy at 2.0 Gy per day, 5 days a week for 5 weeks. All cases were following the dose volume histogram (DVH) constraints. The maximum and minimum tumor dose constraints were 6,700 cGy and 6,500 cGy, respectively. The rectum dose constraints were <35% over 50 Gy. The bladder dose constraints were <35% over 40 Gy. The femur head dose constraints were <15% over 20 Gy. Tumor dose in the 3DCRT were 66 Gy. In IMRT, the maximum dose of PTV was 104.4% and minimum dose was 89.5% for given dose. In 3DCRT, the maximum dose of PTV was 105.3% and minimum dose was 85.5% for given dose. The rectum dose was 34.0% over 50 Gy in IMRT compared with 63.3% in 3DCRT. The bladder dose was 30.1% over 40 Gy in IMRT compared with 30.6% in 3DCRT. The right femur head dose was 9.5% over 20 Gy in IMRT compared with 17.5% in 3DCRT. The left femur head dose was 10.6% over 20 Gy in IMRT compared with 18.3% in 3 DCRT. The dose of critical organs (rectum, bladder, and femur head) in IMRT showed to reduce than dose of 3DCRT. The rectum dose over 50 Gy in IMRT was reduced 29.3% than 3DCRT. The bladder dose over 40 Gy in IMRT was similar to 3DCRT. The femur head dose over 20 Gy in IMRT was reduced about 7~8% than 3DCRT.

PURPOSE: Pandemic influenza A (H1N1) virus has spread rapidly and prompt diagnosis is needed for successful treatment and prevention of transmission. We investigated clinical predictors, validated the use of previous criteria with laboratory tests, and evaluated the clinical criteria for H1N1 infection in the Korean population. MATERIALS AND METHODS: We analyzed clinical and laboratory evaluation data from outpatient clinics at Severance Hospital in Seoul, Korea between November 11 and December 5, 2009. RESULTS: This analysis included a total of 828 patients. Of these, 372 (44.9%) patients were confirmed with H1N1 infection by real-time reverse transcriptase-polymerase chain reaction (RT-PCR). The most common and predictive symptom was cough (90.3%, OR 8.87, 95% CI 5.89-13.38) and about 40% of H1N1-positive patients were afebrile. The best predictive model of H1N1 infection was cough plus fever or myalgia. The sensitivities, specificities, positive predictive values, and negative predictive values of our suggested criteria were 73.9%, 69.5%, 66.4%, and 76.6%, respectively. CONCLUSION: Cough was the most common independent symptom in patients with laboratory-confirmed H1N1 infection, and while not perfect, the combination of cough plus fever or myalgia is suggested as clinical diagnostic criteria. Health care providers in Korea should suspect a cough without fever to be an early symptom of H1N1 infection.
