Granulosa cell tumor of the testis is extremly rare in adult males and granulosa cell tumor occurring in the paratesticular area has not been reported. We report a paratesticular granulosa cell tumor in a 34-year-old man who presented with a 5.5 cm sized scrotal mass. The tumor was present in the paratesticular area near the head of epididymis. It was located in the tunica and completely separated from the testis by thick fibrous tissue. Microscopically, the tumor exhibited solid, microfollicular, and trabecular patterns. The tumor cells had ovoid to elongated nuclei with longitudinal intranuclear grooves and one or two nucleoli and scanty cytoplasm. Mitoses were relatively frequent with an average number of 9/10 HPFs. The tumor extended into the visceral tunica vaginalis and showed multiple lymphatic tumor emboli. Immunohisto chemical stains revealed diffuse strong positivity for inhibin, vimentin, and keratin and diffuse weak positivity for estrogen and progesteron receptor. Placental alkaline phosphatase (PLAP) and epithelial membrane antigen (EMA) were negative. On electron microscopic examination, tumor cells were polygonal and had large indented nuclei. The cytoplasm contained a moderate number of small round mitochondria, abundant rough and smooth endoplasmic reticula, and a few lipid droplets. Small aggregates of intermediate filaments and intercellular junctions were observed. The patient was alive and well 5 months after orchiectomy. This is the first case of adult granulosa cell tumor arising in the paratesticular area.

Journal of Nutrition and Health 2018;51(4):323-329
PURPOSE: The dried body of Scolopendra subspinipes mutilans has long been used as a traditional Korean medicinal food, but little is known about its mechanisms of action. In this study, we investigated the anti-inflammatory activities of Scolopendra subspinipes mutilans and possible mechanisms in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. METHODS: Cytotoxicity of Scolopendra subspinipes mutilans extract (SSME) was measured by MTT assay, anti-inflammatory activities were analyzed by nitric oxide (NO) production, the expression of inducible NO synthase (iNOS) and the mRNA level of pro-inflammatory cytokines such as interleukin-1β (IL-1β) and interleukin-6 (IL-6). Nuclear translocation of nuclear factor-kappa B (NF-κB) p65 subunit and degradation of inhibitory kappa B (IκB) were examined by western blot. RESULTS: SSME inhibited LPS-induced NO production and iNOS expression without cytotoxicity. Up-regulation of LPS-induced pro-inflammatory cytokines, IL-1β and IL-6 was dose dependently attenuated by SSME. Exposure of pyrrolidine dithiocarbamate, an NF-κB specific inhibitor, accelerated the inhibitory effects of SSME on NO production and iNOS expression in LPS-stimulated cells. Moreover, translocation of NF-κB from the cytosol to the nucleus and degradation of IκB were decreased by treatment with SSME in LPS-induced cells. CONCLUSION: These results suggest that the SSME might have the inhibitory effects on inflammation, partly through inhibition of the NF-κB signaling pathway.

PURPOSE: To evaluate various types and; characteristics of non-retinal lesions associated with ultra-wide field scanning laser ophthalmoscope images. METHODS: This retrospective study included 139 eyes of 139 patients with non-retinal lesions observed on color images obtained using Optomap 200Tx (Optos PLC, Dunfermline, Scotland, UK). The non-retinal lesion is a hyperreflective or hyporeflective shadow due to anterior segment of the eye or vitreous except the retina. Types and characteristics of red laser separation, green laser separation and autofluorescence images of non-retinal lesions were evaluated. RESULTS: All non-retinal lesions in images were categorized into 2 groups according to the location of non-retinal lesions. The anterior non-retinal lesions group included corneal opacity, cataract and posterior capsular opacity. The posterior non-retinal lesions group included asteroid hyalosis, posterior vitreous detachment, vitreous opacity and vitreous hemorrhage. Anterior non-retinal lesions were more often hyporeflective in red and green laser separation images (p < 0.001). Posterior non-retinal lesions were more often hyperreflective in green laser separation images and hyporeflective in red laser separation images (p < 0.001). CONCLUSIONS: Ultra-wide field scanning laser ophthalmoscope images can frequently have various shadows from anterior or posterior lesions of the eye. These shadows show a difference in reflectivity depending on their origins. To understand the difference helps in the interpretation of the fundus images.

PURPOSE: Neuroinflammation is mediated by activation of microglia implicated in the pathogenesis of neurodegenerative disorders such as Alzheimer's disease and Parkinson's disease. Inhibition of neuroinflammation may be an effective solution to treat these brain disorders. Petalonia binghamiae is known as a traditional food, based on multiple biological activities such as anti-oxidant and anti-obesity. In present study, the anti-neuroinflammatory potential of Petalonia binghamiae was investigated in LPS-stimulated BV2 microglial cells. METHODS: Cell viability was measured by MTT assay. Production of nitric oxide (NO) was examined using Griess reagent. Expression of inducible NO synthase (iNOS) and cyclooxygenase-2 (COX-2) was detected by Western blot analysis. Activation of nuclear factor κB (NF-κB) signaling was examined by nuclear translocation of NF-κB p65 subunit and phosphorylation of IκB. RESULTS: Extract of Petalonia binghamiae significantly inhibited LPS-stimulated NO production and iNOS/COX-2 protein expression in a dose-dependent manner without cytotoxicity. Pretreatment with Petalonia binghamiae suppressed LPS-induced NF-κB p65 nuclear translocation and phosphorylation of IκB. Co-treatment with Petalonia binghamiae and pyrrolidine duthiocarbamate (PDTC), an NF-κB inhibitor, reduced LPS-stimulated NO release compared to that in PB-treated or PDTC-treated cells. CONCLUSION: The present results indicate that extract of Petalonia binghamiae exerts anti-neuroinflammation activities, partly through inhibition of NF-κB signaling. These findings suggest that Petalonia binghamiae might have therapeutic potential in relation to neuroinflammation and neurodegenerative diseases.

A 35-year-old man was admitted with a 20 day history of generalized edema and muscular weakness of the lower extremities. He was alert with a pale puffy face and an ejection murmur was heard at the cardiac apex. The electrocardiogram disclosed low voltage, first degree atrioventricular block, and a right bundle branch block. During the hospitalization an intractable diastolic hypotension developed, which measured 0 mmHg at the lowest point. At that time the echocardiogram revealed a dilated, akinetic right ventricle. Eventually a multiorgan failure developed and an autopsy following his death presented a fibrofatty replacement of the right ventricular myocardium. This might be a case of an arrhythmogenic right ventricular dysplasia/cardiomyopathy, which is usually characterized clinically by a ventricular tachycardia and may cause a sudden death in young adults.

PURPOSE: To assess the difference between auditory and visual stimuli when determining hemispheric language dominance by using functional MRI. MATERIALS AND METHODS: In ten healthy adult volunteers (8 right-handed, 1 left-handed, 1 ambidextrous), motor language activation in axial slices of frontal lobe was mapped on a Simens 1.5T Vision Plus system using single-shot EPI. Series of 120 consecutive images per section were acquired during three cycles of task activation and rest. During each activation, a series of four syllables was delivered by means of both a visual and auditory method, and the volunteers were asked to mentally generate words starting with each syllable. In both inferior frontal gyri and whole frontal lobes, lateralization indices were calculated from the activated pixels. We determined the language dominant hemisphere, and compared the results of the visual method and the auditory method. RESULTS: Seven right-handed persons were left-hemisphere dominant, and one left-handed and one ambidextrous person were right-hemisphere dominant. Five of nine persons demonstrated larger lateralization indices with the auditory method than the visual method, while the remaining four showed larger lateralization indices with the visual method. No statistically significant difference was noted when comparing the results of the two methods(p>0.05). CONCLUSION: When determining hemispheric language dominance using functional MRI, the two methods are equally appropriate.

OBJECTIVE: Dystonia is a movement disorder in which muscles contract uncontrollably. Acute drug-induced dystonia (DID) can be diagnosed through detailed history taking and physical examination. This study aimed to identify the clinical characteristics of DID in children, which could help emergency physicians diagnose these conditions more efficiently. METHODS: We reviewed medical records of children aged below 18 years diagnosed with drug-related dystonia after discharge from the emergency department over 10 years. We collected the patients’ age, sex, suspected causative drugs, initial diagnosis of the prescribing physician, duration of drug-taking, diagnostic evaluations, treatment methods, and prognosis. RESULTS: Seventy-nine patients were enrolled. The mean age was 11.3±4.9 years (range, 4.0 months to 18.0 years), and 41 patients (51.9%) were boys. The most common cause of DID was gastrointestinal medications in 45 patients (57.0%), followed by antipsychotics in 23 patients (29.1%). Eleven (24.4%) out of 45 patients with DID due to gastrointestinal medications had the initial diagnosis of upper respiratory infection, and seven (30.4%) out of 23 patients with DID due to antipsychotics had the initial diagnosis of non-psychotic diseases. Younger children received more diagnostic procedures and were more frequently admitted. A benzodiazepine (67.1%) was the most common single drug for treatment. CONCLUSION: Physicians should not only acknowledge DID in order to reduce unnecessary workup and admission, but also know that antiemetics and antipsychotics are common causes of DID. Therefore, physicians should try to avoid multidrug prescriptions in children.

IgG4-related sclerosing disease (IgG4-RSD) is characterized by extensive IgG4-positive plasma cell and T-lymphocyte infiltration of various organs. However, the nasal cavity is an extremely rare site of involvement. The authors experienced three cases of igG4-RSD in the nasal cavity. A 54-year-old woman presented with a nasal cavity mass on endoscopic exam and computed tomography (CT) revealed not only a hypoenhancing mass in the right nasal cavity but also a pituitary gland macroadenoma. Endoscopic removal and endoscopic TSA were performed. A 20-year-old man diagnosed with chronic sinusitis, underwent endoscopic sinus surgery. A 26-year-old woman showed thickening of the nasal septum and cribriform plate, and an infiltrating soft tissue lesion in right the alveolar process on CT and an endoscopic biopsy was performed. Pathologic specimens of all cases showed IgG4-positive plasma cell infiltration, consistent with IgG4-RSD. Serum IgG4 levels were checked in two of the cases, and the results were within normal range. All cases were further treated with methylprednisolone and all showed clinical improvement.
