  • Purpose: The purpose of this study was to identify cerebral cortices related with sexual arousal fro visual sexual stimulation in healthy males using BOLD-based functional MR imaging Method: Sixteen male volunteers with sexually potent(mean age:24) were examined for thi study. Functional MRI was performed on a 1.5T MR scanner(GE Signa Horizon) with birdcage-type head coil. In this study, blood oxygenation level dependent(BOLD) technique was utilized to create fMR image reflecting local brain activities. The BOLD-based fMRI d were obtained from 7 oblique planes using gradient-echo EPI with $90^{\circ}$flip angle, 50ms TE 6000ms TR, $26cm{\times}26$ cm FOV, $128{\times}128$ matrix, and 10mm slice thickness. The sexual stimulation paradigm consisted of two alternating periods of rest and activati and it began with a 1 minute rest, followed by a 2 minute stimulation by a documentary a erotic video film. Brain activation maps were generated by cross-correlation of imag acquired during rest and activation periods. The index of activation was used to compare t number of pixels activated by each task in each volunteer, where the significance of th differences was evaluated by using Students t-test.

  • Bronchiolitis interstitial pneumonitis (BIP), an unclassified and newly described interstitial pneumonia, has a combined feature of prominent bronchiolitis, interstitial inflammation, and fibrosis. It is distinct from bronchiolitis obliterans or bronchiolitis obliterans organizing pneumonia (BOOP). BIP has a better prognosis than common cases of interstitial pneumonia. However, BIP has a poorer prognosis than BOOP. BIP's response to corticosteroids is not as successful as BOOP's response to this treatment. We encountered the case of a 31-year-old woman with BIP with an initial presentation of dyspnea and a cough that had lasted for 3 months. The patient's chest CT scan demonstrated patchy ground glass opacities and multiple ill-defined centrilobular nodules in both lungs, suggesting military tuberculosis or nontuberculous mycobacterial infection. A video-assisted thoracoscopic lung biopsy resulted in the diagnosis of BIP. Clinical symptoms, pulmonary lesions, and pulmonary function tests were improved after oral glucocorticoid therapy.

  • Acute eosinophilic pneumonia (AEP) is a disease characterized by an acute febrile onset, eosinophilia in bronchoalveolar lavage fluid, and a dramatic response to corticosteroids. Although many studies have reported a close relationship between direct cigarette smoking and AEP, few studies have identified an association between passive smoking and AEP. Here, we report a case of AEP in a 19-year-old female with cough, fever, and dyspnea after 4 weeks of intense exposure to secondhand smoke for 6 to 8 hours a day in an enclosed area.

  • The occurrence of polyneuropathy in association with monoclonal gammopathy of undetermined significance (MGUS) is quite common. However, reports of MGUS associated cranial neuropathies are rare. A 63 year-old women was presented with diplopia and swallowing difficulty. Neurological examination showed limitation of abduction of right eye, right peripheral facial palsy, decreased hearing and gag reflex, left side deviation of uvula, and decreased DTR. Sensorimotor polyneuropathy were observed with elctrophysiological studies. Protein and immunoelectrophoresis revealed IgG ${\kappa}$monoclonal gammopathy. She was treated with intravenous immunoglobulin and steroid, and her symptoms and signs were improved. This case suggested that she had sensorimotor polyneuropathy and multiple cranial neuropathies associated with IgG ${\kappa}$MGUS.

  • The facial cleft and duplicated maxilla are lire congenital anomaly. After Rushton and Walker had reported a unilateral facial cleft with excess tooth and bone formation in 1937, few authors described similar cases. The etiology of this anomaly is not well understood, but considered embryologically as a neurocristopathy. A neurocristopathy is defined as a condition arising from aberrations in early migration, growth and differentiation of neural crest cells. This aberrations result in facial malformation such as facial clefts and loss or duplication of facial structures. We experienced a male newborn baby with bilateral facial cleft and duplicated maxilla. The cleft was surgically corrected when he was 5 months old. The function and appearance of lip are improved. Duplicated maxilla will be surgically removed. We report this case with review of literatures.

  • To investigate the receptors mediating the regulation of norepinephrine (NE) release in human cerebral cortex slices, we examined the effects of opioid agonists for ${\mu}$-, ${\delta}$-, and ${\kappa}$-receptors on the high potassium (15 mM)-evoked release of [$^3H$]NE. [$^3H$]NE release induced by high potassium was calcium-dependent and tetrodotoxin-sensitive. [$D-Pen^2$, $D-Pen^5$]enkephalin (DPDPE) and deltorphin II (Delt II) inhibited the stimulated release of norepinephrine in a dose-dependent manner. However, Tyr-D-Ala-Gly-(Me)Phe-Gly-ol and U69,593 did not influence the NE release. Inhibitory effect of DPDPE and Delt-II was antagonized by naloxone, naltrindole, 7-benzylidenaltrexone and naltriben. These results suggest that both ${\delta}_1$ and ${\delta}_2$ receptors are involved in regulation of NE release in human cerebral cortex.

  • Malignant fibrous histiocytoma (MFH), a type of sarcoma, is a malignant neoplasm with uncertain origins that arise from both the soft tissues and the bone. The occurrence of MFH on the chest wall is extremely rare. We hereby report a case of a 72-year-old woman who was incidentally detected with MFH after a traffic accident.
