Traditionally the mast cell has been known to he a cell component dwells in annective tissue. But oocasional epithelial mast cells were presented both in light microscopic and electron microscapic examinations. This study was undertaken to evaluate the presence of mast ceil in epidermis of diseased skin. A total of 93 biopsy specimes obtained from the skin lesions of patients with various dermatological conditions were examined with light microacope after toluidine blue stain. The results are as follows: 1. Mast cells were shown in the epidermis of 2 patients with chronic eczema and one patient with pustular psoriasis. 2. Most of the epidermal mast cells were located in ar nearby the basal ceII layer. 3. Epidrmal mast cells have an oval or round nucleus and variable amounts of granulesin the cytoplasm. Some of the cells have a halo-like clear zone around them.

Cervical pregnancy is a rare form of ectopic pregnancy and it can cause life-threatening bleeding. Until recently abdominal hysterectomy has been considered the standard therapy for fear of profuse hemorrhage. Methotrexate, however, can be useful agent to conserve further fertility and it is used in various routes of administration. We report a case of cervical pregnancy that was successfully treated by intraamniotic methotrexate injection under the guidance of transvaginal ultrasonography and subsequent four systemic doses thereafter.

The purpose of this study was to assess the knee strength and anterior laxity in between primary and revision anterior cruciate ligament (ACL) reconstruction. It was a cross-sectional study; 28 patients who had undergone revision ACL reconstruction and the another 30 patients who had primary ACL reconstruction once were compared each other which they all had been operated during the same period of season with the same technique in the same hospital. The isokinetic equipment was used to measure the main outcome for knee strength, and KT-2000 arthrometer was used for measuring anterior drawer test in 12 months post-reconstruction surgery. In the anterior drawer test, we found out that there were significantly differences between primary and revision ACL reconstruction groups (1.5±1.1 mm vs. 2.6±1.5 mm, p=0.001). There was no significant difference in the deficits of knee extensor and flexor muscle strength between primary and revision ACL reconstruction. Revision reconstruction groups have more laxity in anterior drawer than primary reconstruction groups. After revision ACL, the deficits of knee extensor and knee flexor muscle strength have no significantly difference from primary ACL reconstruction.

In this study, the cause, diagnosis, and treatment of common lower limb injuries during the sports activities were presented. Sports injuries of the lower limbs are the most common injuries in the sports medicine field due to the high level of use of the lower limbs during sports activities. The common causes of leg injuries in athletes are traumatic force over the critical limit of normal tissue, repetitive microtrauma, and overuse. Common hip and pelvis problems encountered by the authors include trochanteric bursitis, snapping hip syndrome, and labral tears. The anterior and posterior cruciate ligaments, medial and lateral collateral ligaments, and meniscus have been most frequently involved in sports injuries affecting the knees. Lateral ankle sprain represents one of common injuries in the athletic population. Common overuse injuries are tendinopathies, stress fractures, chronic exertional compartment syndrome, and shin splints. Athletic activity provides a variety of positive benefits to participants' health. To safely continue those activities, an injury prevention program focusing on injuries that may occur in specific sports activities is recommended for participants. Early diagnosis and proper treatment are also important in promoting prompt recovery and preventing secondary injuries.

PURPOSE: Accurate diagnosis of acute pyelonephritis(APN) using clinical and laboratory parameters is often difficult in children. Clinical and experimental studies have demonstrated that renal scarring can be prevented or diminished by early diagnosis and aggressive treatment of acute pyelonephritis. dimercaptosuccinic acid(DMSA) renal scan has been reported to be useful in children for confirmation of the diagnosis of acute pyelonephritis. An analysis was undertaken to correlate the clinical and laboratory manifestations of APN with the results of the DMSA renal scan in different age groups. METHODS: We determined the sensitivity of DMSA renal scan in febrile urinary tract infections(UTI) in two groups according to age:group I in less than 2 years; group II in older than 2 years. During the period March 2001 through September 2002, 67 children presented with febrile UTIs. All patients had DMSA renal scan done in the acute period, 55 had voiding cystourethrography(VCUG) and 66 had renal ultrasonogram(RUS) done. RESULTS: There were no significant difference between the two groups in DMSA renal scan (P>0.05). But, in group I sensitivity of DMSA renal scan was 47%; in group II sensitivity of DMSA renal scan was 70%. The grade of reflux correlated with a positive DMSA renal scan. Vesicoureteral reflux did not correlate with age. RUS did not correlate with a positive DMSA renal scan in any age group. Abnormality of RUS did not correlate with age. CONCLUSION: At present, we believe that DMSA renal scan is the prevailing method in differention of the APN. In addition, it is not invasive and less costly. Even though there is no statistical difference in the sensitivity of DMSA renal scan between young and older children, we can observe that in the younger group, the sensitivity of DMSA renal scan seemed to be lower(47%).

Anterior cruciate ligament (ACL) reconstruction is frequently performed to restore knee stability and function following ACL injury. Little is known about the outcome differences between man and women patients after anterior cruciate ligament reconstruction. Therefore, the purpose of the present study was compared between the genders after a minimum of 1 year following arthroscopic ACL reconstruction. Between 2012 and 2015, 30 men (mean age, 27.0+/-8.7 years) and 30 women (mean age, 25.3+/-7.2 years) who had undergone primary ACL reconstructions were recruited from Samsung Medical Centers. We assessed the knee laxity using the KT-2000 arthrometer, and subjective functional questionnaire was assessed with the Lysholm score and International Knee Documentation Committee (IKDC) subject score. Also we had measured the performance test which is single-leg hop test. As a result, no significant gender differences were found at knee laxity and knee Lyshlom and IKDC score. However, there is significantly difference between men and women with only single-leg hop test. Compared to male patients, female patients reported significantly less single-leg hop distance and less improvement 1 year after reconstruction. Subjective criteria failed to detect clinically significant differences in KT-2000 arthrometer, and subjective functional questionnaire result between men and women. However, we had found that women got less hop distance than men which means more safety functional test must be required before returning to sports.

To identify how influence preoperative predictable factors for knee function after one year of anterior cruciate ligament reconstruction (ACLR). The purpose of this study is to investigate the relationship of preoperative quadriceps strength and post-operative knee function scores (Lysholm score and International Knee Documentation Committee [IKDC] score) after surgery. We extracted seventy-one subjects who underwent hamstring autograft reconstruction to evaluate randomly. Muscle strength deficits were measured with CSMI isokinetic dynamometer. One year after ACLR, we collected these scores from subjects completed. After identification of baseline independent variables between quadriceps muscle strength deficits and both Lysholm score and IKDC score, we examined that how relevant influence in these relationship with these factors by classifying quartile groups. We demonstrated that quadriceps muscles strength and knee function scores were identified as significant correlation. It was compared with quartile outcome in order to analyze that how different result comes out as a degree of deficit. As a result, the only Q1 group who indicated less quadriceps muscle strength deficit (within 23% deficits) effected to knee function scores after one year surgery. The less of quadriceps muscle strength deficit indicated before surgery, the better functional knee score level turns up. Therefore, the result verified that there are significantly positive influences between these relationships after one year of ACLR.
