PURPOSE: To evaluate the effect of topical cyclosporine 0.05% (Restasis; Allergan, Irving, CA, USA) on tear osmolarity in patients with dry eye disease. METHODS: The present study was a single-center, randomized, prospective, and longitudinal trial. Patients who had been using artificial tears to treat dry eye disease were prescribed cyclosporine 0.05% and evaluated using tear osmolarity, tear break-up time, ocular surface staining score, Schirmer test, and the Ocular Surface Disease Index for symptomatic improvement. Clinical measurements of commonly used objective tests were performed at baseline and after 1, 3, and 6 months. RESULTS: At the end of the study, patients demonstrated statistically significant improvement in tear break-up time (6.26 +/- 1.26 sec at 3 months vs. 4.41 +/- 1.63 sec at baseline, p = 0.022) and OSDI (34.98 +/- 20.19 at 3 months vs. 45.02 +/- 22.38 at baseline, p = 0.032) only at 3 months. Other measures such as Schirmer test, ocular surface grade, and tear osmolarity also showed improvement. However, the differences were not significant. CONCLUSIONS: Over a 6-month period, topical cyclosporine 0.05% showed beneficial effects on symptoms and other commonly used signs of dry eye disease for 3 months; however, the tear osmolarity values were not significantly improved.

Papillary thyroid cancer is a common endocrine cancer and commonly presents with lymph node metastases. It has been generally accepted that lymphatic drainage occurs from the thyroid primarily to the central lymphatic compartment and secondarily to the lateral compartment nodes. Recently, improvements in the resolution of imaging studies and the availability of highly sensitive thyroglobulin assays have highlighted the importance of identifying disease in the pre-operative assessment and dealing effectively with metastatic regional disease in order to prevent recurrence. However, there are limitations to diagnosing central lymph node metastases. With unreliable imaging modalities, prophylactic central lymph node dissection should be performed on all patients with papillary thyroid cancer. In comparison with the central compartment, prophylactic lateral node dissection has little or no effect on improving the prognosis of patients with papillary thyroid cancer. Therefore, lateral node dissection is recommended only as a part of the therapeutic procedure. The extension of lateral neck dissection is recommended a comprehensive selective neck dissection of levels IIa, III, IV, and Vb. The rich lymphatic supply of the thyroid gland coupled with the propensity for nodal metastases in papillary thyroid cancer require the modern thyroid surgeon to be familiar with the indications for and techniques of regional lymph node dissection.

OBJECTIVE: To compare the multiplex-PCR and hybrid capture methods for detection of Human papillomavirus (HPV) in uterine cervical swab samples. METHODS: This study determined the HPV infection and its risk group (subtype) in uterine cervical swab samples of 91 Korean women by HPV hybrid capture I and multiplex-PCR method. RESULTS: The prevalence of HPV infection determined by muliplex-PCR was more higher than by hybrid capture method I. Of 65 women with nonspecific uterine cervical lesions, the frequence of HPV-positivity was 14/65 (12 low-risk and 2 high-risk HPV) by hybrid capture method I and was 37/65 (34 low-risk and 3 high- risk HPV) by multiplex-PCR method, respectively. The frequence of high-risk HPV was 2/6 in LSIL, 7/14 in HSIL, 4/6 in uterine cervical cancer by hybrid capture method I, and was 2/6 in LSIL, 8/14 in HSIL, 4/6 in uterine cervical cancer by multiplex-PCR method. CONCLUSION: These results suggest that multiplex-PCR is more sensitive, simple and cost-effective technique than Hybrid-capture I in the detection of HPV infection in the uterine cervix.

OBJECTIVE: This study was carried out to compare the clinical outcome of elective single cleavage-embryo transfer (eSCET) to that of elective single blastocyst-embryo transfer (eSBET) in human IVF-ET. METHODS: This study was a retrospective study which analyzed for 614 women who visited the Daegu Maria Clinic from August 2008 to December 2009. All were under 37 years old and had more than 8 mm of endometrial thickness on the day of hCG administration and at least one good quality embryo on day 3. The eSCETs were performed on day 3 (n=450) and the eSBETs were conducted on day 5 (n=164). RESULTS: The numbers of retrieved oocytes, fertilized oocytes, and day 3 good quality embryos were significantly lower in the eSCET group (12.1+/-6.0, 8.2+/-4.6, and 4.2+/-3.1, respectively) compared to the eSBET group (16.7+/-7.2, 12.1+/-5.0, and 8.5+/-4.5, respectively; p<0.001). However, the clinical pregnancy, implantation, on-going pregnancy, and live birth rates of the eSCET group (46.7, 46.9, 40.0, and 36.7%, respectively) were not statistically different from those of the eSBET group (51.2, 51.8, 45.1, and 43.9%, respectively; p=0.318, 0.278, 0.254, and 0.103, respectively). CONCLUSION: These results suggested that elective single embryo transfer should be performed regardless of the developmental stage to women less than 37 years old who had more than 8 mm of endometrial thickness on the hCG administration day and at least one good quality embryo on day 3 in order to reduce the twin pregnancy rate without reducing the whole pregnancy rate.

The aim of this study is to investigate the effects of electroacupuncture, corticosteroid, and combination of two treatments on ambulatory paresis due to spinal cord injury in dogs by comparing therapeutic effects of electroacupuncture and corticosteroid. Spinal cord injury was induced in twenty healthy dogs (2.5~7 kg and 2~4 years) by foreign body insertion which compressed about 25% of spinal cord. There was no conscious proprioception, no extensor postural thrust, and ambulatory. Dogs were divided into four groups according to the treatment; corticosteroid (group A), electroacupuncture (group B), corticosteroid and electroacupuncture (group AB), and control (group C). Neurological examination was performed everyday to evaluate the spinal cord dysfunction until motor functions were returned to normal. Somatosensory evoked potentials (SEPs) were measured for objective and accurate evaluations. The latency in measured potentials was converted into the velocity for the evaluation of spinal cord dysfunctions. Pain perceptions were normal from pre-operation to 5 weeks after operation. Recovery days of conscious proprioception in groups A, B, AB, and C were 21.2+/-8.5 days, 19.8+/-4.3 days, 8.2+/-2.6 days, and 46.6+/-3.7 days, respectively. Recovery days of extensor postural thrust in group A, group B, group AB, and group C were 12.8+/-6.8 days, 13.8+/-4.8 days, 5.4+/-1.8 days, and 38.2+/-4.2 days, respectively. There were no significant differences between group A and group B. However, recovery days of group AB was significantly shorter than that of other groups and that of group C was significantly delayed (p<0.05). Conduction velocities of each group were significantly decreased after induction of spinal cord injury on SEPs (p<0.05) and they showed a tendency to return to normal when motor functions were recovered. According to these results, it was considered that the combination of corticosteroid and electroacupuncture was the most therapeutically effective for ambulatory paresis due to spinal cord injury in dogs.

OBJECTIVE: This study was performed to compare the clinical outcome of elective single embryo transfer (eSET) performed at the cleavage stage to that of elective double embryo transfer (eDET). METHODS: Of the women less than 36 years old who visited Daegu Maria from January 2008 to April 2009, the only women (n=330) with more than 8 mm of endometrial thickness and at least one good quality embryo, who were treated with GnRH agonist long protocol, were included in this study. After information about complications that can arise by multiple embryo transfer, either eSET or eDET was conducted by their request (167 and 163, respectively). RESULTS: The implantation rate of eSET group was significantly higher than that of eDET group (53.9% vs. 40.2%, p<0.01). The twin pregnancy rate of eSET group was significantly lower than that of eDET group (1.1% vs. 32.3%, p<0.001). However, there were no significant differences between two groups in the clinical pregnancy (53.3% vs. 60.7%, p=0.172), ongoing pregnancy (47.3% vs. 54.6%, p=0.185) and live birth rates (44.9% vs. 50.9%, p=0.275). The number of the surplus embryos which developed to the blastocyst stage and cryopreserved at that stage was significantly higher in eSET group than that of eDET group (3.2+/-2.6 vs. 2.1+/-2.4, p<0.001). CONCLUSION: These results suggest that eSET should reduce significantly the multiple baby pregnancy without decreasing the whole pregnancy rate in women with less than 36 years old.

BACKGROUND: Class II malocclusion patients with hyperdivergent facial types are characterized by short mandibular body lengths and anterior open bite. Accordingly, the treatment for hyperdivergent skeletal class II malocclusion is a lengthening of the mandibular body length and a counterclockwise rotation of the mandible. To prevent post-operative relapse, botulinum toxin-A (BTX-A) injection can be a retention modality.CASE PRESENTATION: A class II open-bite patient received BTX-A injection to the anterior belly of her digastric muscle for the prevention of post-operative relapse. The relapse was evaluated via a clinical examination and a lateral cephalometric radiograph after the completion of post-surgical orthodontic treatment. The patient showed stable occlusion without any signs of relapse at 15 months post-operatively. CONCLUSION In this case presentation, a single injection into the anterior belly of the digastric muscle was sufficient for the prevention of post-operative open bite.

Purpose: By utilizing both protein and mRNA expression patterns, we can identify more detailed and diverse immune cells, providing insights into understanding the complex immune landscape in cancer ecosystems. Materials and Methods: This study was performed by obtaining publicly available Cellular Indexing of Transcriptomes and Epitopes by Sequencing (CITE-seq) data of peripheral blood mononuclear cells (PBMCs) from the Gene Expression Omnibus database. A total of 94674 total cells were analyzed, of which 32412 were T cells. There were 228 protein features and 16262 mRNA features in the data.The Seurat package was used for quality control and preprocessing, principal component analysis was performed, and Uniform Manifold Approximation and Projection was used to visualize the clusters. Protein and mRNA levels in the CITE-seq were analyzed. Results: We observed that a subset of T cells in the clusters generated at the protein level divided better. By identifying mRNA markers that were highly correlated with the CD4 and CD8 proteins and cross-validating CD26 and CD99 markers using flow cytometry, we found that CD4 + and CD8+ T cells were better discriminated in PBMCs. Weighted Nearest Neighbor clustering results identified a previously unobserved T cell subset. Conclusion In this study, we used CITE-seq data to confirm that protein expression patterns could be used to identify cells more precisely. These findings will improve our understanding of the heterogeneity of immune cells in the future and provide valuable insights into the complexity of the immune response in health and disease.
