PURPOSE: The outcome of hip arthroscopy as a treatment of patients with hip dysplasia is variable. In patients with severe hip dysplasia, arthroscopy has the potential to exacerbate instability and unfavorable outcome. To the best of out knowledge, there has not been a report regarding arthroscopic treatment in patients with borderline hip dysplasia in Korea. We favorable outcome with using arthroscopy to treat symptomatic borderline hip dysplasia. MATERIALS AND METHODS: Between August 2010 and February 2015, 143 patients undergoing hip arthroscopy for intra-articular hip disorder were retrospectively enrolled. From this cohort, a borderline dysplasia group compromising 29 patient with lateral center edge angle (LCEA) >18° and <25° and a minimum of 1 years follow-up, was identified. Patient-reported outcome scores, including modified Harris hip score, the hip outcome score-activity of daily living, the sport-specific subscale, visual analogue scale (VAS) and satisfaction survey were obtained preoperatively and at postoperative 3 months, 6 months, 1 year, 2 years, and 3 years. Revision surgery and complications were recorded for each group. RESULTS: The mean age was 35.7 years (range, 16–63 years) years respectively. There were 16 females (55.2%) and 13 males (44.8%). The mean LCEA was 22.0° (range, 18°–25°) and the mean Tönnis angle was 6.1° (range, 0°–18°). The mean follow-up was 20.2 months (range, 12–39 months), and at the 1 year follow-up, there was significant improvement (p<0.001) in all patient reported outcome scores and VAS. Satisfaction survey showed an average score of 7.7. CONCLUSION: In patients with borderline hip dysplasia, if there is an occurrence of symptomatic labral tear, arthroscopic labral refixation has a good short-term result. Therefore, if patients have no response to conservative treatment or have severe pain, arthroscopic labral refixation is a useful treatment options to relieve symptom.

PURPOSE: Total hip arthroplasty was performed using a direct anterior approach (DAA) on an ordinary operation table and a short femoral stem. The clinical radiographic results were evaluated by a comparison with those performed using the modified hardinge (anterolateral approach, ALA) method. MATERIALS AND METHODS: From January 2013 to November 2015, 102 patients who underwent total hip arthroplasty using DAA (DAA group) and the same number of patients using ALA (ALA group), both performed by a single surgeon, were compared and analyzed retrospectively. The operation time and amounts of bleeding were compared, and the improvement in post-operative pain, ambulatory capacity and functional recovery of the hip joint were checked. The location of insertion of the acetabular cup and femoral stem were evaluated radiologically, and the complications that occurred in the two groups were investigated. RESULTS: The amount of bleeding was significantly smaller in the DAA group (p=0.018). Up to 3 weeks postoperatively, recovery of hip muscle strength was significantly higher in the DAA group (flexion/extension strength p=0.023, abduction strength p=0.031). The Harris hip score was significantly better in the DAA group for up to 3 months (p<0.001) and the Koval score showed significantly better results in the DAA group up to 6 weeks (p≤0.001). The visual analogue scale score improvement was significantly higher in the DAA group by day 7 (p=0.035). The inclination angle (p<0.001) and anteversion angle (p<0.001) of the acetabular cup were located in the safe zone of the DAA group more than in the ALA group, and there was no statistically significant difference in the position of the femur stem and leg length difference. During surgery, two cases of greater trochanter fracture occurred in the DAA group (p=0.155). CONCLUSION: The DAA performed in the ordinary operation table using a short femoral stem showed post-operative early functional recovery. Because a simple to use fluoroscope was used during surgery with an anatomical position familiar to the surgeon, it is considered to be useful for the insertion of implants into the desired position and for an approach that is useful for the prevention of leg length differences.

Hemarthrosis occurring after arthroscopic surgery for lesions of the shoulder joint is a very rare complication that can develop due to an injury to the blood vessels when an anterior portal is formed. This is a complication that rarely develops in patients who are taking antithrombotic drugs or who do not have associated diseases, such as thrombocytopenia. We report a case of hemarthrosis that occurred after performing arthroscopic surgery to repair a rotator cuff tear in a patient with a stenosis in an arteriovenous fistula for hemodialysis in the ipsilateral upper arm.

Betulinic acid (3-beta-hydroxy-lup20[29]-en-28-oic acid) has attracted significant attention due to its diverse biological and pharmacological activities, including anti-inflammatory, antimicrobial, antiviral, antidiabetic, antimalarial, anti-human immunodeficiency virus, and antitumor effects. However, its effectiveness against oral cancer remains unknown. This study aimed to evaluate the effect of betulinic acid on the induction of apoptosis in FaDu human pharyngeal carcinoma cells by performing 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) assay, LIVE/DEAD stain, 4',6-diamidino-2-phenylindole (DAPI) stain and western blot. In the MTT assay, LIVE/DEAD stain, and DAPI stain analyses, betulinic acid increased FaDu cell apoptosis in a concentration-dependent manner. Apoptosis induced by betulinic acid in FaDu cells was mediated by the expression of Fas and the activation of caspase-8, caspase-3, and poly (ADP-ribose) polymerase. Western blotting revealed that B-cell lymphoma 2 (Bcl-2) and B-cell lymphoma-extra large were downregulated, while Bcl-2-associated death promoter and Bcl-2-associated X protein were upregulated by betulinic acid in FaDu cells. These findings indicate that betulinic acid inhibits cell proliferation in FaDu human pharyngeal carcinoma cells and induces apoptosis through both apoptotic receptor-mediated exogenous apoptosis and mitochondrialmediated endogenous apoptosis pathways.

Jejunogastric intussusception is a rare, but potentially lethal complication after gastrectomy or gastrojejunostomy. In the acute condition, early diagnosis and prompt surgical treatment are mandatory to reduce the incidence of mortality. We present here a case of jejunogastric intussusception that was diagnosed by gastroscopy in a patient with a history of subtotal gastrectomy, and she had experienced increasing epigastric pain and vomiting for 1 day.

Anisakiasis in the gastrointestinal tract is caused by the ingestion of raw marine fish that contain Anisakis lavae. In rare cases, Anisakiasis is found as an eosinophilic granuloma that mimics a submucosal tumor. The diagnosis is usually made after surgical resection. Several cases of gastric anisakiasis imitating a submucosal lesion have been reported. However, colonic anisakiasis forming a submucosal lesion is very rare and only a few cases have been reported. All of the cases were confirmed after surgery. Recently, we encountered a male patient with a submucosal lesion on the ascending colon during a health screening. Several biopsies were performed on the same site as the lesion. The pathological finding was eosinophilic granuloma. We tentatively diagnosed the patient with eosinophilic granuloma due to Anisakis as the patient consumed raw seafood and eosinophilia was detected on a laboratory test. We decided not to perform any procedure. One month later, the eosinophilic granuloma disappeared as seen on a follow-up colonoscopy.
