BACKGROUND AND PURPOSE: The most-common initial manifestation of Miller Fisher syndrome (MFS) is diplopia due to acute ophthalmoplegia. However, few studies have focused on ocular motility findings in MFS. This study aimed to determine the pattern of extraocular muscle (EOM) paresis in MFS patients. METHODS: We consecutively recruited MFS patients who presented with ophthalmoplegia between 2010 and 2015. The involved EOMs and the strabismus pattern in the primary position were analyzed. Antecedent infections, other involved cranial nerves, and laboratory findings were also reviewed. We compared the characteristics of the patients according to the severity of ophthalmoplegia between complete ophthalmoplegia (CO) and incomplete ophthalmoplegia (IO). RESULTS: Twenty-five patients (15 males and 10 females) with bilateral ophthalmoplegia were included in the study. The most-involved and last-to-recover EOM was the lateral rectus muscle. CO and IO were observed in 11 and 14 patients, respectively. The patients were aged 59.0±18.4 years (mean±SD) in the CO group and 24.9±7.4 years in the IO group (p<0.01), and comprised 63.6% and 21.4% females, respectively (p=0.049). Elevated cerebrospinal fluid protein was identified in 60.0% of patients with CO and 7.7% of patients with IO (p=0.019) for a mean follow-up time from the initial symptom onset of 3.7 days. CONCLUSIONS: The lateral rectus muscle is the most-involved and last-to-recover EOM in ophthalmoplegia. The CO patients were much older and were more likely to be female and have an elevation of cerebrospinal fluid protein than the IO patients.

Since G.N. Hounsfield's clinical use of computed tomography in 1971, digital imaging technique using computers has shown an eye opening progress. Progress has made 3-dimensional understanding of not only facial bones but muscles and other connective tissues possible through 3-dimensional reconstruction of preexisting tomographical images. Also, quantitative analysis of density, distance, volume has become possible, allowing objective analysis of preoperative and postoperative states through imaging. The authors measured the masseter muscle volume of 20 normal individuals and 8 female patients through 3-D reconstructive CT imaging and made a statistical analysis of the measurements. The method used in our study may be applied to the diagnosis of disease causing the change of the facial volume and presurgical design as a useful tool to provide objective information on the evaluation of surgery outcome.

Parotid sialolithiasis accounts for 10 to 20% of all cases of sialolithiasis that involves the head and neck and presents management challenges for a variety of reasons. In this report, we present a rare case of removing a double stone in Stensen's duct by anexternal approach (open parotid sialolithotomy).

BACKGROUND: Despite proposing clonal depletion, anergy, and alternation of cytokines in peripheral tolerance, the precise mechanism for the immunosuppressive effect of blood transfusion remains unknown. Here, we evaluated the effect of transfusion on the immune system indirectly via quantitation of leukocyte cytokine mRNA expression before and after allogeneic transfusion. METHODS: Samples were obtained from eight patients, being ordered one to four units of leukocytefree erythrocytes, before, 1, and 7 days after transfusion, from November to December, 2002 at Inha University Hospital. We explored the changes in mRNA expression of interleukin-2 (IL-2), IL-4, IL-10, tumor necrosis factor alpha (TNF-alpha) and interferon gamma (IFN-gamma). RESULTS: In four patients who received blood transfusions among eight, significant changes were observed in the blood mRNA levels of INF-gamma and IL-10. The amounts of IFN-gamma mRNA were significantly decreased a day after transfusion to 78.5% and then recovered to 110.9% 7 days later (P=0.032), whereas, that of IL-10 was increased to 151.5% a day after and recovered to 119.1% 7 days later (P=0.034). mRNA expressions of IL-2, IL-4, and TNF-alpha were not detected in all patients. CONCLUSIONS: We observed a significant decrease in leukocyte IFN-gamma mRNA expression and an increase in IL-10 mRNA after transfusion. These findings indirectly represent that down-regulation of the Th1 cells and the up-regulation of the Th2 cells could be caused by allogeneic transfusion.

BACKGROUND: For monitoring infection and inflammation episodes, biomarkers of host response, such as C-reactive protein (CRP) and procalcitonin (PCT), are now being recognized as useful tools in the diagnostic process. We aimed at evaluating the analytical performance of the recently developed semi-automated ichroma SMART system (Boditech Med Inc., Korea), which allows measurements of both CRP and PCT. METHODS: We evaluated the analytical performance of the ichroma SMART system and the agreement between its results and the laboratory standards for CRP and PCT measurements. The precision and linearity as well as the method of measurement were compared to the DxC 800 (Beckman Coulter, USA) for CRP and to the VIDAS (bioMerieux SA, France) for PCT, according to corresponding CLSI guidelines. Additionally, we evaluated the carryover rates between specimens. RESULTS: The total precision (% CV) of the ichroma SMART system in measuring low, middle, and high level controls (level 1, 2, 3) was 6.32%, 5.75%, and 3.56% for CRP, and 8.07%, 6.24%, and 6.53% for PCT. In the linearity test, R2 was 0.9997 and 0.9982 for CRP (0.1-336.8 mg/L) and PCT (0.05-60.91 ng/mL), respectively. Good correlation was observed between ichroma SMART and DxC 800 for CRP (r=0.997), and between ichroma SMART and VIDAS for PCT (r=0.992). Carry-over effect was 0.02% for CRP and 0.04% for PCT. CONCLUSIONS: The ichroma SMART system showed an adequate performance and appeared to be a suitable clinical analyzer with a simple operating procedure for the measurement of CRP and PCT.

OBJECTIVES: In order to determine find out the best methods for a more objective detection of neurologic abnormality in early hand arm vibration syndrome(HAVS), early with analyzing the validity of each of the detection methods was analyzed. We evaluated the relationships between the sensorineural stage of Stockholm-revised vibration syndrome classification and the results of several tests. METHODS: 497 workers were investigated for symptom, exposure duration, the types of tools used, and medical history from January 2000 to December 2007. Pain sense threshold, vibrotactile threshold, hand grasp force, finger grasp force, and a finger tapping frequency test were performed by the workers. RESULTS: The grinder(67.3%) was the most commonly used tool and the mean exposure duration was 14.8 years. Although the pain sense and vibrotactile threshold level tended to increase according to sensorineural stage of the Stockholm classification, there was statistically significant difference in the vibrotactile threshold of 125, 250 Hz (p=0.006~0.038) but not in the pain sense threshold. Hand and finger grasp force tended to decrease according to the sensorineural stage of Stockholm classification and there was statistically significant difference(p=0.041,<0.001, 0.034) only on the right hand side. The tapping frequency also generally decreased according to the sensorineural stage of the Stockholm classification and there was statistically significant difference (p=0.002~0.019) only on the left hand side. CONCLUSIONS: Although there is no single standardized method that can objectively diagnose the sensorineural component of early HAVS early, the combination of subjective symptoms, the sensorineural stage of Stockholm classification, the pain and vibrotactile threshold test, the hand and finger grasp force, and the finger agility (tapping) test can objectively detect sensorineural component of HAVS early.
