Splenic metastasis from solid cancer is a rare clinical event. Especially splenic metastasis from the lung is very rare. Most spleen metastases are found at autopsy and are part of a widely spread disease. Solitary splenic metastasis in the abscence of other metastases is extremely rare. The authors report the case of a 54-year-old man in whom the only discover distant metastasis from lung cancer was a splenic mass. The splenic lesion was detected after the resection of the primary lung lesion. The time from diagnosis to the development of splenic metastasis was 25 months. The rarity of a solitary spleen metastasis from lung cancer and the treatment modalities are discussed. When solitary spleen metastasis is suspected in a clinical setting, aggressive treatment is indicated, a splenectomy followed by combined modality treatment to prevent the spread and aggravation of the disease.

PURPOSE: Male sexual desire and erection are directly or indirectly affected by hormone and neuroendocrine response. We investigate the changes of the serum dopamine and testosterone level by visual erotic stimulation-induced sexual excitement. MATERIALS AND METHODS: The age of volunteers was ranged from 25 to 65 years, with an average of 45.5years. Serum were collected at rest and after visual erotic stimulation. Sexual excitement induced by erotic film for 30 minutes and erectile status was monitored by Rigiscan. The response of visual erotic stimulation were divided into three groups according to degree of sexual excitement. i.e. no response (Group I), mild excitement(Group II), excitement (Group III). RESULTS: Although some changes were observed in serum dopamine and testosterone level of all 32 patients after visual erotic stimulation, it did not showed statistically signigicant change (p=0.450, p=0.058). According to excitement response, group I and II were not showed statistically significant change in both dopamine and testosterone. Only dopamine of the group III was showed statistically change (dopamine: p=0.041, testosteron: p=0.257) CONCLUSIONS: In this study, serum testosterone level is not showed significant change irrespective of the degree of sexual excitement induced by visual erotic stimulation. However, serum dopamine was changed with statistically significance only in sexual excitement group.

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.

Schwannomas are uncommon benign, slowly growing tumors that originate in peripheral, cranial, or autonomic nerves and are composed of Schwann cells in a collagenous matrix. Retroperitoneum is often the site of occurrence of schwannoma, but report on schwannoma of the adrenal gland is rare. We report a case of adrenal schwannoma. A 53 male had facial edema and paresthesia of extremities for 3 month. Incidentally adrenal mass was found on abdominal computer tomogram and exploration performed.

OBJECTIVE: To evaluate the differences in maxillomandibular transverse measurements at either the crown or the estimated center of resistance (CR), and to compare values between normal occlusion and Class III malocclusion groups. METHODS: Dental casts and computed tomography (CT) data from 30 individuals with normal occlusion and 30 with skeletal Class III malocclusions were evaluated. Using the casts, dental arch widths (DAWs) were measured from the cusp tips, and basal arch widths (BAWs-cast) were measured as the distance between the points at the mucogingival junction adjacent to the respective cusp tips. The BAWs determined from CT (BAWs-CT) images were measured from the estimated CRs of the teeth. RESULTS: None of the DAW measurements or maxillomandibular DAW differences showed statistically significant intergroup differences. In contrast, the maxillary BAWs-CT and BAWs-cast were lesser in the Class III malocclusion group than in the normal occlusion group. The mandibular BAWs-CT were significantly greater in the Class III malocclusion group than in the normal occlusion group. Moreover, the maxillomandibular BAW differences on both CT and cast showed significant intergroup differences in all transverse measurements. CONCLUSIONS: The maxillomandibular DAW differences showed no significant intergroup differences. In contrast, the maxillomandibular BAW differences on both CT and cast showed significant intergroup differences in all transverse measurements. The maxillomandibular BAW differences at the estimated CRs, measured using CT or casts, can reveal underlying transverse maxillary basal arch deficiencies in patients with skeletal Class III malocclusions.

OBJECTIVE: To evaluate the association between progression of curvature of scoliosis, and correction for functional component in patients with juvenile idiopathic scoliosis (JIS). METHODS: We retrospectively reviewed medical data of patients prescribed custom molded foot orthosis (FO) to correct inequality of RCSPA (resting calcaneal stance position angle), and chose 52 patients (26 females, 26 males) with Cobb angle ≥10° in radiology and uneven pelvic level at iliac crest by different RCSPA (≥3°) as a factor of functional scoliosis. They had different hump angle ≥5° in forward bending test, for idiopathic scoliosis component. Their mean age and mean period of wearing FO were 79.5±10.6 months and 18.6±0.70 months. RESULTS: Cobb angle was reduced from 22.03°±4.39° initially to 18.86°±7.53° after wearing FO. Pelvis height difference and RCSPA difference, were reduced from 1.07±0.25 cm initially to 0.60±0.36, and from 4.25°±0.71° initially to 1.71°±0.75° (p < 0.01). Cobb angle improved most in 9 months. However, there was no significant improvement for those with more than 25° of Cobb angle initially. Mean Cobb angle improved in all age groups, but patients less than 6 years had clinically significant improvement of more than 5°. CONCLUSION: JIS can have functional components, which should be identified and managed. Foot orthosis is useful in correcting functional factors, in the case of pelvic inequality caused by different RCSPA, for patients with juvenile idiopathic scoliosis.

This study examined the disinfection conditions (exposure time, 0–30 min; exposure temperature, 4℃–65℃) of hypochlorous acid water (HOCl) in automobile disinfection equipment. The study tested poliovirus type 1 (PV1), low pathogenic avian influenza virus (AIV, H9N2), and foot and mouth disease virus (FMDV, O type). As a result, the PV1 and FMD viruses were inactivated easily (virus titer 4 log value) by HOCl (> 100 ppm) but the AIV required higher exposure temperatures (> 55℃). In conclusion, the exposure temperature and time are important factors in deactivating AIV and FMDV.

Synovial sarcoma occurring in the pleura and lung is extremely rare. We report a case of pleuropulmonary synovial sarcoma as a second malignant neoplasm. The patient had been diagnosed with acute myelomonocytic leukemia at 5 years of age, and received matched sibling donor allogeneic bone marrow transplantation, with total body irradiation and cyclophosphamide conditioning. At 22 years of age, he complained of worsening chest discomfort and exertional dyspnea. Chest CT revealed a huge mass in the right middle lobe, pleura, and diaphragm. The patient was initially diagnosed as sarcomatoid malignant mesothelioma, without any environmental or occupational asbestos exposure. Five months later, the patient presented with soft tissue metastasis and underwent needle biopsy. Pathological examination including SYT-SSX RT-PCR revealed synovial sarcoma, which led to a review of the original tumor findings and confirmed the diagnosis of pleuropulmonary synovial sarcoma.To the best of our knowledge, our patient is the first case of pleuropulmonary synovial sarcoma developed after allogeneic hematopoietic stem cell transplantation.
