We report a case of 4-year-old girl with erythematous papule and nodule on the right knee and left knee, respectively. Histopathologically, the findings of walls of the each cystic lesions were those of the epidermal cyst containing hair shafts of lanugo size on the right knee and the trichilemmal cyst on the left knee. The observation of hair shafts in a cystic cavity represents an important clue for identifying some unusual varieties of cystic lesions. We report a interesting case of epidermal cyst containing hair shafts and trichilemmal cyst simultaneously and independently occurred on the right knee and left knee, respectively.

Solar urticaria is an uncommon disorder characterized by pruritus, erythema and whealing occurring minutes after exposure to sunlight or artificial radiation, and generally resolves in a few hours. A 46-year-old woman presented with a 2-year history of pruritus and whealing, which occurred immediately after exposure to sunlight. Phototesting elicited urticarial reactions in the UVA and visible sepectra. The results of passive and reverse passive transfer studies were all negative. The patient was treated with cetirizine, doxepin and prednisolone. After 2 months of the treatment, the symptoms did not appear.

PURPOSE: The purpose of this study is to assess the clinical utility of multiplanar reformation images of helical CT in the evaluation of pancreatic diseases. MATERIALS AND METHODS: Helical CT scans of the pancreas were obtained in 30 patients with pancreatic diseases. Helical CT was performed with 5mm collimation at 5mm/sec table speed during rapid injection of intravenous contrast agent using power injector. After scanning, helical volume data were reconstructed at 2mm interval and then multiplanar reformation of the pancreas and adjacent structures was done. In both prospective reconstructed axial images and multiplanar reformation images, detection of pancreatic lesion, extent of lesion, and vascular and bile ductal changes were analyzed with a grading system of 1,2, 3. RESULTS: The mean grade of detection of pancreatic lesions was 2.37 in the prospective axial image and 2.83 in multiplanar reformation image, extent of diseases was 2.40 in prospective axial image and 2.97 in multiplanar reformation image, and vascular and bile ductal changes was 2.00 in the prospective axial image and 2.97 in multiplanar reformation image. All the differences were statistically significant (P<0.0001). CONCLUSION: Multiplanar reformation images of helical CT are useful in the evaluation of pancreatic diseases and especially in the demonstratibn of complex anatomic relationships between the pancreas and surrounding structures.

Although ventricular pacing alone initially had deemed adequate for most clinical situations, some patients did not do well after ventricular pacing was initiated, and developed various symptoms attributed to this mode of pacing. The pacemaker syndrome is complex of clinical signs and symptoms related to the adverse hemodynamic and electrophysiologic consequences of ventricular pacing in the absence of other causes. Neurologic symptoms or those congestive heart failure predominated. We recently experienced a case of pacemaker syndrome in a 44-year-old female who had suffered sick sinus syndrome and was implanted with dual chamber pacing system being programmed to VVI pacing. She complained of chest discomfort, dyspnea, and near-fainting in a day after being programmed to VVI. Blood pressure was decreased to 9/60mmHg. Electrocardiography showed toPwave onT wave, representing retrograde ventriculoatrial conduction. The symptoms and signs were disappeared immediately after the pacing system was programmed to DDD pacing.

OBJECTIVES: This study measures serum prostate-specific antigen (PSA) levels in tire-manufacturing workers, and attempts to find occupational or non-occupational factors that related to their PSA levels. METHODS: A total of 1,958 healthy male workers (1,699 were production workers and 259 were office workers) took PSA measurement for analysis. RESULTS: After adjusting for age, body mass index, hypertension, regular exercise, alcohol drinking and smoking, which were significantly related to serum PSA levels or known related factors of serum PSA levels, the geometric mean PSA levels were significantly high in the office workers (p = 0.017), the older age group (p < 0.001), the group with hypertension (p = 0.046) and the group of individuals that do not exercise regularly (p = 0.015) and the office workers were more likely to have a serum PSA level of > or =4.0 (OR 7.73, 95% CI: 2.78-21.46) or 2.5 ng/mL (OR 2.74, 95% CI: 1.49-5.08). After stratifying by age and adjusting aforementioned covariates, office workers 50 years of age and older had the significantly higher geometric mean PSA levels (p = 0.017) and were more likely to have a serum PSA level of > or =4.0 ng/mL (OR 12.90, 95% CI: 3.65-45.64) or 2.5 ng/mL (OR 3.90, 95% CI: 1.64-9.25) than production workers 50 years of age and older. CONCLUSIONS: This study showed that serum PSA levels were significantly higher among the group with hypertension or the group of individuals that did not exercise regularly or group of office workers who were considered to have lesser physical activities.

PURPOSE: The objective of this study is to report our initial experience about the feasibility, effectiveness, and safety of transobturator tension-free vaginal mesh (Prolift(TM)) and concomitant tension-free vaginal tape (TVT) as a treatment of female anterior vaginal wall prolapse associated with stress urinary incontinence (SUI). MATERIALS AND METHODS: We reviewed the charts of patients who underwent Prolift(TM) and TVT between April 2009 and March 2010. All patients had a physical examination and staging of cystocele. According to the International Continence Society system 2, 5 and 3 women had stage grade II, III and IV respectively. All the patients underwent pelvic examination 1, 3, 6 month and 1 year after operation and anatomical and functional outcomes were recorded. An anatomic cure after intervention was defined as stage 0 and an improvement was defined as stage I. Anatomic failures were defined as stage II or higher on the last physical examination. RESULTS: The mean follow-up was 7.1 (1-11) months. Overall success rate of cystocele repair was 90%. The anatomical cure rate of cystocele was 50%. The cystocele repair improved 4 patients, but failed in 1. SUI was cured in all patients. No significant complications including bladder or vessel injury and mesh related erosion occurred. The postoperative complication was transient voiding difficulty (2 cases). CONCLUSIONS: These preliminary results suggest that Prolift(TM) and TVT offer a safe and effective treatment for female anterior vaginal wall prolapse and SUI. However, a long-term follow up is necessary in order to support the good result maintenance.

PURPOSE: To evaluate characteristic MR findings of craniocerebral anomaly and its relationship with neurologic manifestations. MATERIALS AND METHODS: We retrospectively reviewed MR images of 36 patients with craniocerebral anomaly diagnosed by MRI and clinical courses. We correlated the characteristic MR findings in 41 lesions with neurologic manifestastions focusing on seizures and developmental delay. RESULTS: Twenty-three patients with seizures consisted of 14 patients(60%) with neuronal migration disorders and seven(30%) with phakomatosis, among which 18 patients(78%) had generalized type of seizures. Locations of the lesions were the parietal lobes in 11 patients(52%) and the subependymal or periventricular regions in seven(33%). Two patients with tuberous sclerosis had the lesions in both parietal and subependymal areas. Nine patients had the signs of developmental delay that were seen in the four(44%) with schizencephaly, two (22%) with tuberous sclerosis, two(22%) with heterotopia, and one(ll %) with pachygyria. CONCLUSION: Neuronal migration anomaly was relatively common lesion that presented neurologic manifestations such as seizures and developmental delay. Generalized type of seizures was common. We were able to diagnose these anomalies using the MRI that helped establish therapeutic plans.

Herpes zoster can be associated with a number of neurologic complications but meningoencephalitis with herpes zoster is rarely seen. We report a case of herpes zoster ophthalmicus followed by the meningoencephalitis, which developed during treatment with acyclovir infusion. A 73-year-old male patient developed a fever and mental confusion on the third day of the treatment. Neurological examination revealed neck stiffess, increased deep tendon reflex and positive Babinski sign. The cerebrospinal fluid examination revealed increased opening pressure, increased protein and a lymphocytic pleocytosis. The glucose level was decreased, which is a very unusual feature in viral meningoencephalitis.
