Background: The purpose of this study is to evaluate results of superior labrum anterior to posterior (SLAP) repairs and debridement of type II SLAP lesions combined with Bankart lesions. Methods: Between 2010 and 2014, total 58 patients with anterior shoulder instability due to a Bankart lesion combined with a type II SLAP lesion were enrolled. Patients were divided into two groups: group C consisted of 30 patients, each with a communicated Bankart and type II SLAP lesion and group NC consisted of 28 patients, each with a non-communicated Bankart and type II SLAP lesion. Bankart repairs were performed for all patients. SLAP lesions were repaired in group C and debrided in group NC. Clinical results were analysed to compare groups C and NC by using the visual analogue scale pain score, American Shoulder and Elbow Surgeons score, Constant scores, Rowe score for instability and range of motion assessments. Results: The clinical scores were improved in both groups at final follow-up. Also, there were no differences between two groups. No significant difference was found in terms of the range of motion measured at the last follow-up. The number of suture anchors used was significantly higher in group C than in group NC (5.6 vs. 3.8; p=0.021). Conclusions: In this study, it is considered that Bankart repair and SLAP debridement could be a treatment option in patients with a non-communicated type II SLAP lesion combined with a Bankart lesion (study design: IV, therapeutic study, case series).

Objectives : This study was designed to find clinical factors that could be differentiated by the lateralization of lesion and also find clinical factors to predict the lateralization of lesion. Methods : The subjects were 65 cooperative inpatients and outpatients with non-traumatic subcortical cerebrovascular disease without neurologic and psychiatric history from January 1995 to September 1995 ; 48 patients in Kyung Hee University, Oriental Medicine Hospital, 35 patients in Anam Hospital, Korea University were examined as subjects, but authors excluded 20 patients whose data were incomplete or who had uncertain lesions on brain CT or MRI. The 65 patients were divided into three groups-group with left hemispheric lesion, group with right hemispheric lesion, group with both hemispheric lesion-according to the finding of brain imaging study. Their cognitive functions were evaluated by the Benton Neuropsychological Assessment(BNA), their subjective neurobehavioral symptoms by Symptom Check List-90-R(SCL-90-R), their objective neurobehavioral symptoms by Neurobehavioral Rating Scale, and their daily living functions by Geriatric Evaluation by Relative's Rating Instrument(GERRl) and Instrumental Activities of Daily Living Scale(IADLs). Results : The results were as follows : 1) The results of cognitive function test indicated that the group with right hemispheric lesion showed low functions in Tactile Form Perception(left), the group with left hemispheric lesion showed low functions in Finger localization(right), the group with right hemispheric lesion showed low functions in Finger Localization(left). 2) Though, there were little significant differences in subjective neurobehavioral symptoms, the group with right hemispheric lesion showed higher scores in all symptoms except hostility. 3) Though, there were little significant differences in objective neurobehavioral symptoms, the group with both hemispheric lesion showed higher scores in cognition, guilty/disinhibition, the group with left hemispheric lesion showed higher scores in lability of mood, the group with right hemispheric lesion showed highest scores in psychotism, neurotism, agitation-hostility and decreased motivation/emotional withdrawal. 4) There were little significant differences among three groups in Daily Living Functions, but the group with right hemispheric lesion showed the lowest functions in Instrumental Activities of Daily Living. 5) As a result of discriminant analysis on each factor's contribution to the prediction of lesion, Finger Localization(left), Phoneme Discrimination and Tactile Form Perception(right) showed that they had the potentiality to predict lesion. Conclusion : The results suggest that there are little significant differences among the groups of three non-traumatic subcortical cerebrovascular disease in cognitive functions, but the group with right hemispheric lesion showed more serious and various changes in subjective and objective neurobehavioral symptoms, and showed low functions in Instrumental Activities of Daily Living. This results suggest the possibility that the decline of the daily living function in the group with right hemispheric lesion were due to various symptoms, not due to cognitive dysfunction. The confirmation of the possibility should be worked out through the follow-up study of some groups containing cortical lesion. Apart from these findings, Finger Localization, Tactile Form Perception(right) and Phoneme Discrimination suggest that they can be used as clinically valuable cognitive parameters that predict the lateralization of lesion in non-traumatic cerebrovascular disease.

Ionophorous antibiotics have been used popularly for the protection of avian coccidiosis, though Halo-fuginone which is derived from an extract of the Dichroa febrifuga, was developed as an antimalarial and anticoccidial agent. The antibiotics are regarded as the causes of residues in the avian products, therefore the author has tried to find out more safe herbal materials for the control of avian coccidiosis. Thus, the extracts of 5 kinds of herbs, roots of Pulsatilla koreana Nakai and Sophora flavescens Aiton, nuts of Quisqualis indica Linne, whole herbs of Artemisia annua Linne and Polygonum aviculare Linne, were investigated on the efficacy against E tenella. Survival rates, bloody diarrhea, lesion scores, body-weight gains and feed conversion rate were investigated at the 1st and the 2nd week after infection. The bloody diarrhea in the groups treated with P koreana, A annua, Q indica and P aviculare were milder than those in the groups treated with S flavescens and infected control. The lesion score in the groups treat.4 with herb extracts(2.00$\pm$0.82~2.65$\pm$0.89) were lower than those in the control group (2.80$\pm$0.7l). But, there was not significant in all infected groups. The body weight gai in the groups treated with P koreana, S flavescens, A annua and Q indica(291.74$\pm$15.76~303.43$\pm$51.90) were higher than that in the control group (283.71$\pm$16.53) but there was not significant. In a conclusion, analyzing the data of the survival rates, bloody diarrheal symptoms, lesion scores, body weight gains and oocyst excretions, the extract of S flavescens, P koreana, A annua and Q indica were effective. The further research on the above herbal materials will have been carried out by the author and the other researchers by means of the chemical analysis of the components.

Purpose: The cerebellum is a region of brain structure that plays an important role in calibrating two different information of neural signal from descending motor commands and from ascending sensory inputs. Damage of the cerebellum shows a variety of classic motor symptoms such as postural and locomotor dysfunctions. Therefore, we tried to investigate motor function and skill in stroke patients with cerebellar lesions in sub-acute stage, and compare with these functions of patients with non-cerebellar lesions. Methods: Total twelve stroke patients with cerebellar lesion and 130 stroke patients with non-cerebellar lesions were retrospectively recruited in this study. For evaluation of motor strength, Motricity index (MI) for upper and lower limbs was tested. For measurement of motor skill function, the modified Brunnstrom classification (MBC), Manual function test (MFT), functional ambulatory category (FAC), and Barthel index were adopted. Results: In comparison of motor strength and motor skill function between two groups, statistical differences between the two groups were significantly observed only in upper MI and FAC. Although no significant differences were found in other variables, stroke patients with cerebellar lesion had higher scores in lower and total MI, MBC, and MFT, whereas they had lower scores in FAC and Barthel index. Conclusion: Our results showed that stroke patients with cerebellar lesion had greater impact on movement functions related to hand motor and walking ability in activities of daily life, compared with patients with non-cerebellar lesion, in spite of similar degree of motor function and skill between the two different lesioned-groups.

Purpose: To evaluate pathologic patterns and outcomes of treatment of a biceps tendon lesion associated with a rotator cuff tear. Materials and Methods: We reviewed 92 patients (i) who underwent surgery for a cuff tear, (ii) for whom the biceps lesion could be observed retrospectively, and (iii) had a minimum follow-up of 2 years. The pathology of biceps tendon was classified into 4 types: tenosynovitis, fraying or hypertrophy, tear, and instability. All but the 4 with massive cuff tears were repaired. The biceps lesions were treated with debridement in 30, tenotomy in 10, tenodesis in 8, and recentering in 4. UCLA scoring was used for clinical results. Results: Seventy patients had a biceps lesion, 19 tenosynovitis, 22 fraying or hypertrophy, 21 a tear, and 8 instability. A biceps lesion was observed in 63% of cases of cuff tears below the medium size, and in 88% of cases with cuff tears above the large size. UCLA scores according to the pathology of the biceps lesion were 29.6 in the absence of a biceps lesion, and 28.3 in its presence. UCLA scores in patients with tenotomy or tenodesis for associated biceps tendon lesions were 28.2. Conclusion: There is a greater incidence and severity of a biceps lesion with a larger cuff tear. Therefore, the cause of a biceps lesion might be related to the cause of the cuff tear. Among the several options of treatment for biceps lesion, tenotomy or tenodesis may be particularly effective in providing pain relief.

To reduce swine production costs, a slaughter check system has been developed in countries with an advanced swine industry. Evaluation of lung lesions in carcasses is a critical part of the slaughter check system. This study was performed to collect background information for use in developing a slaughter check system in Korea. Lung tissues and their gross images were collected from slaughterhouses in Gyeonggi-do, Korea. Scoring of the gross lung lesions was performed on the lung images. Histopathologic examination was conducted to classify the pulmonary lesions as bronchopneumonia or interstitial pneumonia. Scores of the gross lung lesions were significantly different between bronchopneumonia and interstitial pneumonia groups (p < 0.001). A 90% confidence interval of gross lung lesion scores was established for the bronchopneumonia group, and the lesion scoring had a sensitivity of 100% and specificity of 77.3%. The gross lung lesion scoring test was subjected to a diagnostic distinction evaluation by examining the receiver operating characteristic curve and was appraised as having good discrimination for bronchopneumonia. Establishment of a gross lung lesion scoring test for the diagnosis of bronchopneumonia could be valuable as a screening test of macroscopic bronchopneumonia in swine slaughter check system.

Purpose: The purpose of this study is to determine the results of conservative treatment of osteochondral lesion of talus (OLT). This study would be helpful to determine the treatment methods for OLT patients. Materials and Methods: We have established 69 cases of osteochondral lesion of talus, from December 2004 to June 2006 in a period of 18 months. Symptoms were confirmed through survey and a medical examination by interviewing patients. Diagnosis was made through physical examination, simple radiography and MRI. AOFAS score of all the patients were measured. When the patients did not get improved with conservative treatment, surgical operation was done. Results: 27 out of the 69 patients were treated using conservative treatment. Initial AOFAS scored was $66.37{\pm}8.89$ points. After treatment, AOFAS scores had increased to $83.78{\pm}8.48$ points. In cases of surgery, AOFAS scores had increased from $64.17{\pm}13.43$ points preoperatively to $80.45{\pm}8.67$ points. Conclusion: 60% of conservative treatment was useless in treating OLT patients. Surgical operation is still needed to be performed. Therefore, treatment should be done with sufficient understanding of the results.

Many recent studies have reported that the quality of input learning data was vital to the detection of regions of interest. However, due to a lack of research on the quality of learning data on lesion detetcting using gastroscopy, we aimed to quantify the impact of quality difference in endoscopic images to lesion detection models using Image Quality Assessment (IQA) algorithms. Through IQA methods such as BRISQUE (Blind/Referenceless Image Spatial Quality Evaluation), Laplacian Score, and PSNR (Peak Signal-To-Noise) algorithm on 430 sheets of high quality data (HQD) and 430 sheets of low quality data (PQD), we showed that there were significant differences between high and low quality images in lesion detecting through BRISQUE and Laplacian scores (p<0.05). The PSNR value showed 10.62±1.76 dB on average, illustrating the lower lesion detection performance of PQD than HQD. In addition, F1-Score of HQD showed higher detection performance at 77.42±3.36% while F1-Score of PQD showed 66.82±9.07%. Through this study, we hope to contribute to future gastroscopy lesion detection assistance systems that involve IQA algorithms by emphasizing the importance of using high quality data over lower quality data.

This study aimed to systematically review the effectiveness of methylene blue (MB) photosensitizers in the management of symptomatic oral lichen planus (OLP). Electronic online databases and manual searches were performed for randomized controlled trials (RCTs) published in English between January 2010 and February 2022. RCTs comparing photodynamic therapy (PDT) and corticosteroid therapy at baseline and follow-up period were identified. The Cochrane risk of bias tool was used to assess the quality of the included studies. A meta-analysis was performed regarding visual analog scale (VAS) scores, Thongprasom sign scores, lesion size, response to treatment, and exacerbation of lesions after therapy. The clinical severity was analyzed qualitatively. Five RCTs consisting of 180 samples fulfilled the inclusion and exclusion criteria. All parameters of VAS score, Thongprasom sign score, lesion size, and response to treatment were statistically non-significant. Our results indicate that both MB-PDT and corticosteroid therapy are effective for the management of OLP. Moreover, MB-PDT is an effective alternative treatment option for OLP when corticosteroids are contraindicated. However, conclusive evidence cannot be ascertained owing to the heterogeneity among the studies.

The purpose of this study was to examine the effects of stroke patients' cognitive score on their the activities of daily living. The subjects of this study were 30 stroke patients who were admitted to T$\breve{a}$e-Bong hospital from November, 2002 to March, 2003. The subjects were administerd an MMSE as a cognitive assessment and an MBI as a functional assessment upon referral to physical therapy initially. The results were as follows: 1. The MMSE scores for the stroke patients were related to the patients' abilities to perform their activities of daily living. The changes of MBl scores significantly correlated with the changes of MMSE scores (p<.05). 2. The subjects with left hemispheric lesion scored higher in MMSE than those with right hemispheric lesions (p<.05). 3. The hemispheric lesions did not significantly affect the activities of daily living score (p>.05).
