1.Clinical Characteristics of Idiopathic Orbital Inflammation Accompanied with Paranasal Sinusitis.
Journal of the Korean Ophthalmological Society 2017;58(7):776-781
PURPOSE: To investigate the clinical characteristics of idiopathic orbital inflammatory disease (IOI) with paranasal sinusitis. METHODS: This study is a retrospective, comparative case series of patients who were diagnosed with IOI between January 2009 and December 2016. This study included patients with available medical and radiologic data at diagnosis and who participated in follow-up for more than 12 months after treatment. The patients were divided into two groups according to accompaniment of paranasal sinusitis and were compared. RESULTS: Among 101 patients with IOI, 13 (12.9%) were identified to have paranasal sinusitis. The incidence of pain was higher in patients with sinusitis (69.2%) than in patients without sinusitis (25.0%, p = 0.003). More patients with paranasal sinusitis experienced recurrence after systemic steroid therapy (69.2%) than in the other group (34.1%, p = 0.033). Additional immunosuppressants and/or radiation therapy were needed only in 9.1% patients without sinusitis but in 38.5% patients with sinusitis (p = 0.039). CONCLUSIONS: IOI patients with sinusitis showed a significantly higher recurrence rate. More careful follow-up of patients during steroid tapering and treatment of sinusitis might be helpful to prevent recurrence of IOI.

We report here a case of drug-induced acute pancreatitis proved by elimination and single, low dose challenge test in a child with Crohn disease. A 14-year-old boy with moderate/severe Crohn disease was admitted due to high fever and severe epigastric pain during administration of mesalazine and azathioprine. Blood test and abdominal ultrasonography revealed acute pancreatitis. After discontinuance of the medication and supportive care, the symptoms and laboratory findings improved. A single, low dose challenge test was done to confirm the relationship of the adverse drug reaction and acute pancreatitis, and to discriminate the responsible drug. Azathioprine and 6-mercaptopurine showed positive responses, and mesalazine showed a negative response. We introduce the method of single, low dose challenge test and its interpretation for drug-induced pancreatitis.

Infection-induced acute hepatitis complicated with acute pancreatitis is associated with hepatitis A virus, hepatitis B virus or hepatitis E virus. Although rare, Epstein-Barr virus (EBV) infection should be considered also in the differential diagnosis if the patient has acute hepatitis combined with pancreatitis. We report a case of EBV infection with cholestatic hepatitis and pancreatitis with review of literature. An 11-year-old female was admitted due to 1-day history of abdominal pain and vomiting without any clinical symptoms of infectious mononucleosis. Diagnosis of reactivated EBV infection was made by the positive result of viral capsid antigen (VCA) IgM, VCA IgG, Epstein-Barr nuclear antigen and heterophile antibody test. We performed serologic tests and magnetic resonance cholangiopancreatography to exclude other viral or bacterial infection, autoimmune disorder, and structural problems. The patient's symptoms recovered rapidly and blood chemistry returned to normal with conservative treatment similar to previously reported cases.

PURPOSE: To identify the brain centers associated with visually evoked sexual arousal in the human brain, and to investigate the neural mechanism for sexual arousal using functional MRI (fMRI). MATERIALS AND METHODS: A total of 20 sexually potent volunteers consisting of 10 males (mean age: 24) and 10 females (mean age: 23) underwent fMRI on a 1.5 T MR scanner (GE Signa Horizon). The fMRI data were obtained from 7 slices (10 mm slice thickness) parallel to the AC-PC (anterior commissure and posterior commissure) line, giving a total of 511 MR images. The sexual stimulation consisted of a 1-minute rest with black screen, followed by a 4-minute stimulation by an erotic video film, and concluded with a 2-minute rest. The brain activation maps and their quantification were analyzed by the statistical parametric mapping (SPM 99) program. RESULTS: The brain activation regions associated with visual sexual arousal in the limbic system are the posterior cingulate gyrus, parahippocampal gyrus, hypothalamus, medial cingulate gyrus, thalamus, amygdala, anterior cingulate gyrus, insula, hippocampus, caudate nucleus, globus pallidus and putamen. Especially, the parahippocampal gyrus, cingulate gyrus, thalamus and hypothalamus were highly activated in comparison with other areas. The overall activities of the limbic lobe, diencephalon, and basal ganglia were 11.8%, 10.5%, and 3.4%, respectively. In the correlation test between brain activity and sexual arousal, the hypothalamus and thalamus showed positive correlation, but the other brain areas showed no correlation. CONCLUSION: The fMRI is useful to quantitatively evaluate the cerebral activation associated with visually evoked, sexual arousal in the human brain. This result may be helpful by providing clinically valuable information on sexual disorder in humans as well as by increasing the understanding of the neuroanatomical correlates of sexual arousal.

BACKGROUND: There have been a lot of methods that prevent catatrophic airway fires during laser surgery, but none of them can protect endotracheal tube cuff exposed directly to laser beam. This study was performed to know the preventive effect of viscous lidocaine-filled cuffs on laser-induced combustion, and to know how long we can maintain positive pressure ventilation if laser beam broke out cuff perforation. METHODS: Transparent acrylic trachea attached to artificaial lung was intubated with 8.0 ID polyvinylchloride endotracheal tube. Cuff was filled with 8ml of saline or saline and viscous lidocaine mixture with 2:1 or 4:1 ratio. Positive pressure ventilation with air in tidal volume of 500 ml was begun. The laser output was set to 10 watt/sec in the continuous mode with beam diameter of 1 mm. Laser beam was directed perpendicularly at the part of the cuff protruding between endotracheal tube shaft and acrylic trachea, and laser emission was continued until the cuff was perforated or combusted. RESULTS: There was no case of laser-induced fires. After the perforation of cuff, the tidal volume was slowly decreased in 2:1 mixture of saline and viscous lidocaine filled cuff compared to others (P<0.05). CONCLUSION: 2:1 mixture of saline and viscous lidocaine may be used as an efficient inflating material of endotracheal tube cuffs on laser airway surgery.

PURPOSE: To report clinical characteristics of thyroid-associated ophthalmopathy (TAO) in patients who previously underwent total thyroidectomy for thyroid cancer or a benign mass of the thyroid. MATERIALS AND METHODS: Of the patients who were diagnosed with TAO from March 2008 to March 2012, we performed a retrospective chart review on those who had undergone total thyroidectomy for thyroid cancer or a benign mass of the thyroid before the occurrence of ophthalmopathy. RESULTS: Of the 206 patients diagnosed with TAO, seven (3.4%) met the inclusion criteria. The mean age of the subjects was 47.4 years, and all were female. Six patients were diagnosed with papillary thyroid cancer, and one was diagnosed with a benign mass. The duration between total thyroidectomy and onset of TAO ranged from 3-120 months (median 48 months). Ophthalmic manifestations varied among cases. Except for the patient who was diagnosed with a benign mass, all patients showed hyperthyroid status and were under Synthroid hormone treatment at the time of TAO development. Five of these six patients had positive levels of thyroid-stimulating hormone (TSH) receptor autoantibodies. CONCLUSION: TAO rarely develops after total thyroidectomy, and the mechanism of TAO occurrence is unclear. However, most patients showed abnormalities in thyroid function and TSH receptor autoantibodies.

PURPOSE: Orbital varices, which can lead to proptosis or globe displacement, are caused by Valsalva's maneuver or bending forward. Most of the orbital varices are treated conservatively, but surgical treatment is necessary for severe cosmetic or functional problems. We report a case of orbital organizing hematoma accompanied by an orbital varix which was successfully removed surgically without complications such as intraoperative bleeding. CASE SUMMARY: A 78-year-old female presented with the complaint of 4 mm proptosis and hyperglobus of left eye. Orbit magnetic resonance imaging (MRI) showed a well demarcated extraconal mass in the inferior orbit which appeared to be an orbital varix. Initially, we decided to monitor the patient without surgery because proptosis was reduced to 1 mm within a week. However, after 5 months, the symptoms suddenly worsened, specifically, 4 mm of proptosis with severe hyperglobus and pain. MRI showed a 29.7 x 21.2 x 23.7 mm mass compressing the globe upward. Six weeks of conservative care did not improve the symptoms and we eventually performed an anterior orbitotomy through the inferior conjunctiva. There was a minor bleeding during the surgery. Based on the histological test, the mass was determined to be an organizing hematoma covered by a membrane. At 8 months postoperatively, symptoms had not recurred. CONCLUSIONS: Orbital varices are usually treated conservatively since its surgical removal is known to have risks. Nonetheless, if an MRI shows an orbital organizing hematoma, it can be surgically debulked successfully without complications when a chronic hemorrhage from orbital varix causes serious proptosis and globe deviation.

BACKGROUND: The aim of this study was to investigate the value of colonoscopy for assessment of colonic mucosal lesions and for microbial identification in patients with acute diarrhea. METHODS: From March 2000 to August 2000, forty-one patients with watery or bloody diarrhea lasting less than 15 days were participated after the exclusion of patients who had previous history or presumption of inflammatory bowel disease, radiation colitis, ischemic colitis, or pseudomembranous colitis. Both biopsy specimens and colonic luminal fluid were taken during the colonoscopy and used for bacterial cultures. RESULTS: Male and female ratio was 22:19 and mean age was 45+/-20 years. The extent of acute colitis was as followed: the normal colonoscopic finding in five cases (12.2%), involvement of one segment in 3 cases (7.3%), involvement of two or more segments in 14 cases (34.1%), pancolitis in 10 cases (24.4%) and pancolitis with terminal ileitis in 9 cases (22.0%). In culture study, identification of more than one pathogen was in 19/41 (46.3%) and the common pathogens were Enterobacter (11 cases), Salmonella species (6 cases), Citrobacter freundii complex (2 cases), Klebsiella oxytoca (2 cases) and Morganella morganii (1 case). Pathogen could be identified in 11.8% with stool specimen, 46.2% with biopsy specimen and 62.5% with intraluminal fluid, but without statistical significance. CONCLUSION: Colonoscopy was useful in the evaluation of extent and severity of acute infectious colitis. Obtaining the biopsy specimens and intraluminal fluid during colonoscopy seemed to assist in identifying the pathogen in patients with acute diarrhea.
