C-arm fluoroscopy is useful equipment in interventional pain management because it helps to guide correct needle targeting for the accurate injection and drug delivery. However, due to increased use of C-arm fluoroscopy in various pain procedures, the risk of radiation exposure is a significant concern for pain physicians. The harmful biological effects of ionizing radiation on the human body are well known. It is therefore necessary to strive to reduce radiation exposure. Lead aprons with thyroid shields are the most fundamental radiation protective devices for interventional procedures, and are very effective. However, the operator's radiation safety cannot be guaranteed because pain physicians seem to lack sufficient interest, knowledge, and awareness about radiation safety. Also, inappropriate care and use of radiation protective devices may result in a higher risk of radiation exposure. The purpose of this article was to review the literature on radiation safety with a focus on lead aprons and thyroid shields and present recommendations related to those devices during C-arm fluoroscopic-guided interventions by pain physicians.

Intense pulsed light (IPL) Quantum SR(TM) systems are high-intensity light sources, which emit polychromatic light. Unlike laser systems, these flashlamps work with noncoherent light in a broad wavelength spectrum of 560-1200 nm. IPL Quantum SR(TM) has been effective for the treatment of photoaging skin as a nonablative method. Three patients with photoaged skin were treated with fifth full-face treatments at 3-4 week intervals using IPL Quantum SR(TM). The cut-off filters of 560 nm and integrated contact cooling system were utilized for treatments. After the last treatments, the patients showed the overall improvement in clinical appearance, reduction in pigmentation and telangiectasia and fine wrinkle with smoothening of skin textures. Histological evaluations showed new collagen production after treatment. Full-face photorejuvenation using IPL Quantum SR(TM) can be an effective treatment modality for photoaged skin. We report herein IPL photorejuvenation is safe and effective in skin rejuvenation.

PURPOSE: To report a case of refractive change with intraocular pressure change following trauma. METHODS: Changes in intraocular pressure, refractive power, lens thickness, depth of anterior chamber, and axial length of an 8-year-old girl were measured. RESULTS: During the early period after trauma, the patient showed low intraocular pressure and shallow anterior chamber depth. The refractive power changed to transient high myopia. With temporary high intraocular pressure, the refractive power changed to hyperopia and the refractive power recovered toward emmetropia as the intraocular pressure fell to the normal level. Refractive alteration is a result of changes in intraocular pressure and depth of the anterior chamber by cyclodialysis cleft and its adhesion is induced by trauma to the eye. Herein, the authors show evidence for a relationship between refractive change and posttraumatic ocular change.

Striae Distensae is a very common cosmetic problem. The effectiveness of various lasers, such as the 585-nm pulsed dye laser on the treatment of striae distensae has recently been reported. However, the potential pigmentary alteration of dark skin by pulsed dye laser is known. Thermage is a radiofrequency capable of delivering higher energy fluences to a greater volume of tissue than nonablative lasers, with no epidermal injury. We report three patients who had striae distensae. They were treated with Thermage and 585-nm pulsed dye laser. The treatment was effective and safe for dark skin.

Trichoderma spp. cause large crop losses of the cultivated shiitake mushroom, Lentinula edodes. We bred several shiitake strains that are resistant to Trichoderma spp. using di-mon mating to establish a useful method for controlling the greenmold disease. We examined the competitive ability of L. edodes against Trichoderma spp. using a dual culture system to select resistant strains. By screening Trichoderma-resistant strains, we found that among 11 parental strains, 4 strains, including KFRI 36, were confirmed resistant strains. They showed especially strong resistance to T. harzianum, which formed deadlock after mycelial contact and then invaded into the territory of T. harzianum. KFRI 171 also showed resistance to T. atroviride strains. Among 13 strains, which were made by hybridization of shiitake strains, 5 were confirmed to be resistant to Trichoderma, including KFRI 58-1. Their resistance was not correlated to the resistant activity of their parents' strains. Two strains lose resistance and two strains acquire resistance compared to their parents' strains. In SEM observation, the mycelium of L. edodes at the interaction zone of Lentinula-Trichoderma was rugged and swollen by T. harzianum.

Background: Botulinum toxin type A (BTX-A) injection is being widely used off-label for muscular hypertrophy, including deltoid muscle hypertrophy. However, very few studies have evaluated the optimal dosage and its clinical response. Objective: This study aimed to assess the efficacy and safety of different doses of Prabotulinum toxin A (PBoNT) for treating deltoid muscle hypertrophy. Methods: Twelve particiapants with bilateral deltoid muscle hypertrophy were enrolled and randomly received either 16 U or 32 U of PBoNT. In each participant, the same dose was administered to both deltoid muscles. Both participants and evaluators were blinded. Deltoid muscle thickness and upper arm circumference were measured on day 0, and weeks 2, 4, and 12 after the PBoNT injection. Results: Upper arm circumference significantly decreased in both groups; however, deltoid muscle thickness was reduced in the 16 U group only. No major complications were reported in both groups. However, a few minor complications were reported in the 16 U injection group. Conclusion Both 16 U and 32 U of PBoNT intramuscular injections are safe and effective in treating deltoid hypertrophy.

Hemorrhagic cystitis is defined by lower urinary tract symptoms that include dysuria, hematuria, and hemorrhage and is caused by viral or bacterial infection or chemotherapeutic agents. Reports of hemorrhagic cystitis caused by non-typhoidal salmonella (NTS) are extremely rare. We report a case of a 41-year-old man with hemorrhagic cystitis from NTS that caused massive bleeding and shock. The patient was hospitalized for uncontrolled diabetes and obstructive uropathy related to severe cystitis. A urine culture was positive for group D NTS. This case demonstrated that hemorrhagic cystitis in a patient with a risk factor such as diabetes can be a manifestation of local extraintestinal NTS infection.

OBJECTIVE: To analyse sexual assault cases epidemiologically. METHODS: We evaluated 129 female patients who visited the female sexual assault center in northeast area of Seoul with a complaint of sexual assault. After patient's consent was obtained, history taking and physical examination was performed. Photographic record was obtained on appropriate sites. We reviewed their medical and standardized rape records and photographs retrospectively. Descriptive statistics was performed with medico-legal parameters. RESULTS: Of 129 sexual assault victims, 44.2% were under 19 years of age. Spring was relatively vulnerable season for sexual assaults, vulnerable time was between 12 to 18 o'clock for victims younger than 14 years and between 0 to 6 o'clock for victims older than 13 years. Most frequent place was hotel for adolescent victims and was victim's house for other age groups. Sixty seven percent of assailants were strangers to the victims. Genital trauma was more frequent in victims younger than 20 years and alcohol use was more prevalent among adolescent victims. 82.2% of victims visited hospital within 24 hours and 91.4% of victims has destroyed potential physical evidences by bathing, douching, tooth brushing, changing clothes, defecation or urination. Follow up rates are low: 28.7% in obstetrics and gynecology clinic, 5.4% in psychiatric clinic. CONCLUSION: This study provide more accurate information about epidemiology of sexual assaults.

Patients with chronic renal failure (CRF) are known to be more susceptible to tuberculosis infection due to impairment of the host defense mechanism. Although extrapulmonary tuberculosis is more prevalent in those subjects and it may induce dismal outcome, its diagnosis has been challenging since there is no specific symptoms of the disease and the clinical course is usually atypical. Herein, We report a case of disseminated tuberculosis diagnosed by ultrasound-guided liver biopsy in a 31-year-old CRF patient presenting sustained fever despite broad-spectrum antimicrobial therapy and progressive cholestatic jaundice.
