1.Atypical Ocular and Optical Coherence Tomographic Findings With Presumed Miliary Tuberculosis.
Journal of the Korean Ophthalmological Society 2011;52(1):107-111
PURPOSE: To report clinical features and optical coherence tomographic findings of presumed atypical ocular tuberculosis associated with tuberculosis lymphadenitis and encephalomeningitis. CASE SUMMARY: A 28-year-old female with lymphadenitis in the axillary area presented with a fever and headache of a one week duration. CSF study and MRI findings implied tuberculosis encephalomeningitis, and presumed tuberculosis uveitis manifested with visual disturbance after five days. Ocular symptoms were aggravated and showed anterior iridocyclitis, vitritis, macular edema, and multifocal retinitis with miliary granuloma that was distinct from choroiditis or typical tuberculosis granuloma. After the patient received anti-tuberculosis medication and systemic corticosteroids, significant improvements in visual acuity, ocular findings and OCT results were observed. CONCLUSIONS: Ocular tuberculosis can present with various clinical findings, and caution should be taken so as not to misdiagnose based on these characteristics. In the present case, anti-tuberculosis medication and systemic steroids resulted in the resolution of inflammation. In such cases, monitoring the posterior pole lesion via OCT may be helpful in determining improvement.

PURPOSE: The purpose of this study is to correlate the MR findings with clinical stage and clinical outcome, and to describe the evolutional changes of abnormal MR findings of transverse myelitis. MATERIALS AND METHODS: Medical records and spinal MR images of 23 patients with both clinical and radiological diagnosis of transverse myelitis were retrospectively reviewed. MR findings were correlated with clinical stages including interval between MR imaging and full development of clinical symptoms, and compared with the clinical outcome. RESULTS: Diffuse high signal intensity of the spinal cord on T2-weighted image with mild cord bulging (67%) and focal contrast enhancement of the cord (75%) were observed within the first four weeks after full development of clinical symptoms. The findings decreased in extent or vanished later than four weeks on either initial or follow-up MR images. Most patients with either cord atrophy or focal hemorrhagewithin the cord lesion had poor clinical outcome. CONCLUSION: The MR findings of transverse myelitis are nonspecific, which may be seen in a variety of diseases. Serial MRIs, especially follow up examination over at least one month after full development of clinical symptoms are useful in the diagnosis of transverse myelitis and predicting its prognosis.

Ophthalmic complications after tooth extraction are rare but discomforting events. This paper reports the rare complications of a 20-year-old male patient who presented with transient blurring of vision after surgical extraction of several teeth under general anesthesia. Additional diagnostic tests were performed to discern the reason for the pseudomyopia. A literature review was carried out by searching for articles published from 1936 to 2019 using the keywords “dental,” “ophthalmic,” “complication,” “blurring of vision,” and “accommodation disturbance” in PubMed. Only six patients with detailed ophthalmic symptoms similar to those of our patient have been reported. If blurred vision or a myopic shift in refraction is present, pseudomyopia should be suspected, and cycloplegic refraction is essential for diagnosis. The condition improves spontaneously.

BACKGROUND: Chinese traditional osteopathy is long in history, unique in manipulation and miraculous in therapeutic effect. But people understand it more m perception rather than in theory, more in application rather than in development. There is little research truly on the bioseience.OBJECTIVE: To probe into the macro-idea of Chinese traditional osteopathy, micro-mechanisms on characters and mathematics-physics models, aiming to provide new principles and approaches of treatment for the daily increased bone trauma, fracture and sport injury.SETTING: Physics and machine-electron college of a university, and its affiliated hospital.METHODS: Based on the natural concept of "integration between heaven and human being" and new concept of holistic medicine in Chinese traditional osteopathy, the macro-idea and characters of reduction and union of fracture are generalized from the characters of natural therapy and the biomechanical mechanisms and characters of reduction and union of fracture are summarized from the micro-reaction of bone repair and union so as to discover biomechanical mechanisms and characters of reduction and union of fracture and further to set up biomechanical models and mathematics-physics expressions during the treatment.RESULTS: Chinese traditional osteopathy envelopes macro-idea of "initiative reduction-functional union" in fracture and micro-mechanism on "stress adaptability-functional adaptability" of bone repair and union.CONCLUSION: Chinese traditional osteopathy compiles with the natural,green and non-traumatic therapy in bio-natural law of bone repair and union and supports the theme of "high thought and high skill".

BACKGROUND: To evaluate airway responses and inflammation to antigen in Sprague-Dawley rat asthma model, we examined airway responses, serial histologic changes of the lung, and the relationship between airway responses and airway inflammation after antigen airway challenge. METHODS: Sprague-Dawley rats were sensitized with subcutaneous injection of 10 microgram ovalbumin(OA). Antigen airway challenges were done 14 ~16 days after sensitization and the sensitized rats were sacrificed 1h(AE), 6 ~8h(AL) and 1day(AD) after airway challenge, to examine the histologic changes of the lung. Airway responses were measured by body plethysmograph and recorded by enhanced pause(Penh) as an index of airway obstruction 6 ~8h after antigen challenges. Nonsensitized controls(10 rats) were also challenged with antigen and sacrificed 1 day later. Histopathologic examination of two trachea, large bronchi, small bronchi, and vessels was performed to evaluate the severity of inflammation and eosinophilic infiltration with H&E stain. RESULTS: In 17 of 20 rats(85%) in both groups, we observed airway responses. Among them, an early response(ER) in 15 rats(75%), an dual response in 5(25%), and an late response(LR) only in 2 rats(10%) displayed. There were no significant differences in the severity of inflammation among the trachea, large bronchi, small bronchi and vessels in all groups after antigen challenge(p>0.05) and between early and late responders. The significant eosinophil infiltration was observed in 5 rats(50%) of AL(p<0.05) compared with in AE and controls. Also, eosinophil infiltration was observed in higher trend in LR(57.1%) compared to ER(40%)(p>0.05). CONCLUSION: Sprague-Dawley rats sensitized with subcutaneous injection of OA showed a significant airway responses to antigen challenge. But antigen challenges caused a little eosinophil infiltration and no significant airway inflammation. Asthma model of Sprague-Dawley rats could be useful for antigen-induced airway responses, but this model has a limitation for the study of human asthma because of no significant pathologic change.

Peritonitis is a major complication of continuous ambulatory peritoneal dialysis and it remains the leading cause of patient droupout. VRE is a very serious pathogen because it is difficult to eradicate due to very limited effective antibiotics and because there is a possibility of transfer of this resistance to other gram-positive organisms including Staphylo-coccus aureus. We experienced a case of CAPD peritonitis by VRE, which was treated with high dose ampicillin and streptomycin without removal of CAPD catheter. We report our experience of CAPD peritonitis caused by VRE and review the literature.

This study was designed to identify expression of calcium-binding proteins and synaptic reorganizations of dentate mossy fibers in hippocampal sclerosis of human temporal lobe epilepsy. Hippocampal neuronal density was quantitively analyzed in temporal lobe epilepsy group (n=50) to investigate the degree of hippocampal sclerosis and it was compared with that of autopsy control (n=3). To verify the distribution of calcium-binding proteins in neurons of epileptic hippocampi, the parvalbumin (PV)-immunoreactive and calbindin-D28K (CB)-immunoreactive neurons were quantitively analyzed in each area of Ammon's horn by immunohistochemical stain. Also, to clarify synaptic reorganizations of the dentate mossy fibers, a part of each hippocampus was examined under light microscopy and transmission electron microscopy using Timm sulphide silver method. In epileptic hippocampi, severity of hippocampal sclerosis (HS) was graded four, which consisted of 3 cases with no HS, 6 mild HS, 12 moderate HS, and 29 severe HS. The hippocampal neuronal loss was most prominent in CA1, followed by CA4 and CA2. Expression of calcium-binding proteins was more prevalent in CA2 of all groups. The proportion of PV-immunoreactive neurons in CA1 and CA4 significantly increased in the moderate and severe HS group, whereas the proportion of CB-immunoreactive neurons did not correlated with the severity of HS. Timm granules were noted in inner molecular supragranular layer of dentate gyrus of epileptic hippocampi and they tended to increase in proportion along with the severity of hippocampal sclerosis. Transmission electron microscopy showed that supragranular Timm granules corresponded to synaptic terminals of mossy fibers. These results suggest that parvalbumin appears to have more protective effect against neuronal loss and that mossy fiber synaptic reorganization seems to play a major role in pathogenesis of hippocampal sclerosis of human temporal lobe epilepsy.

OBJECTIVES: This study was to evaluate the performance of the newly developed information system (IS) implemented on July 1, 2014 at three public hospitals in Korea. METHODS: User satisfaction scores of twelve key performance indicators of six IS success factors based on the DeLone and McLean IS Success Model were utilized to evaluate IS performance before and after the newly developed system was introduced. RESULTS: All scores increased after system introduction except for the completeness of medical records and impact on the clinical environment. The relationships among six IS factors were also analyzed to identify the important factors influencing three IS success factors (Intention to Use, User Satisfaction, and Net Benefits). All relationships were significant except for the relationships among Service Quality, Intention to Use, and Net Benefits. CONCLUSIONS: The results suggest that hospitals should not only focus on systems and information quality; rather, they should also continuously improve service quality to improve user satisfaction and eventually reach full the potential of IS performance.

OBJECTIVETo investigate the metabolic changes of mice serum after loaded swimming and to provide a basis for the study of anti-fatigue functional food.
METHODSThe male Kunming mice were randomly divided into four group, fed an AIN-93 diet for 14 days, and forced to swim for 30, 60 or 120 min, respectively, with a load on their tails. The mice were executed after swimming immediately and the changes of serum metabolic profiles were analyzed using metabolomic approach. The spectrum was acquired by using Carr Purcell Meiboom Gill (CPMG) or Longitudinal Eddy Current Delay (LED) sequence, and transformed into 1H NMR spectrogram via Fourier transformation. All the data were analyzed by principal component analysis by using the SIMCA-P+ software.
RESULTSThe serum metabolic profiles changed significantly after loaded swimming. Serum beta-hydroxybutyric acid, acetate, lactate, lipid were increased and glucose, choline, phosphorylcholine, alanine and phosphatidylcholine decreased. These changes were time dependent.
CONCLUSIONThe changes of serum metabolic profiles after loaded swimming were time dependent, especially for lipid metabolite.Further study based on the interaction of choline and lipid metabolism may contribute to understand the mechanism of fatigue.
