Purpose: To investigate the extent of bone ingrowth into the porous-coated acetabular cups as well as the factors that correlated with bone ingrowth in total hip arthroplasty. Materials and Methods: Thirty six Harris-Galante porous-coated acetabular cups that were retrieved through revision surgery were examined in this study. Acetabular cups retrieved due to infection or severely destroyed cups (ed note: severe what?) were excluded. The extent of bone ingrowth into the acetabular cups was grossly measured, and its correlation with the variables including age, gender, weight, height, the duration of fixation, size, number of screws, inclination and anteversion was statistically analyzed. Results: The mean proportion of bone ingrowth was 52.9 21.9%(2~90%) and less than 30% in three cups(8.3%). The pattern and the location of bone ingrowth were not consistent. There was no correlation between the extent of bone ingrowth and age, gender, weight, height, the duration of fixation, cup size, number of screws, size, inclination and anteversion. Conclusion: Harris-Galante porous-coated acetabular cups showed satisfactory bone ingrowth regardless of the variables associated with the demographic or surgical conditions. Surface treatments with a fiber-metal porouscoating appears to be suitable for cementless acetabular cups in terms of the long term results.

The location of the motor point of the gastrocnemius muscle was accurately defined relative to surrounding bony landmarks to facilitate the approach to the nerve of the gastrocnemius muscle during treatment for gastrocnemius muscle spasticity. Anatomic dissection of 40 cadaver knees was undertaken for morphometric measurement. The distances from the epicondyle of the femur to the motor branch, and from the motor branch to the motor point of the nerve to the medial head of the gastrocnemius muscle were 3.68 +/- 11.44 mm, and 37.79 +/- 7.80 mm, respectively; while those of the nerve to lateral head of the gastrocnemius muscle were 4.45 +/- 11.96 mm, and 32.16 +/- 4.64 mm, respectively. The tibial nerve lay 44.57 +/- 5.45% and 56.30 +/- 4.73% from the lateral margins of the epicondyle and the fibular head, respectively. Careful consideration of the morphometry of the motor point of the gastrocnemius muscle may provide accurate anatomical guidance, and hence reduce complications during the chemical blockage of these nerves.

Most cases of Middle East Respiratory Syndrome (MERS) infection in Korea (outbreak: May 11-July 4, 2015) occurred in hospital settings, with uncertain transmission modes in some cases. We performed an in-depth investigation epidemiological survey on the 178th case to determine the precise mode of transmission. A 29-year-old man living in Pyeongtaek presented on June 16 with a febrile sensation, chills, and myalgia. Upon confirmatory diagnosis on June 23, he was treated in an isolation room and discharged on July 2 after cure. An epidemiological investigation of all possible infection routes indicated two likely modes of transmission: exposure to MERS in Pyeongtaek St. Mary's Hospital during a visit to his hospitalized father (May 18-29), and infection through frequent contact with his father between the latter's referral to Pyeongtaek Good Samaritan Bagae Hospital for treatment without confirmatory diagnosis until his death (May 29-June 6). Although lack of clear proof or evidence to the contrary does not allow a definitive conclusion, all other possibilities could be excluded by epidemiological inferences. While it is impossible to trace back the modes of transmission of all cases in a large-scale outbreak, case-by-case tracking and isolation of infected individuals and those in close contact with them is important in preventing the spread. Efforts should be made to establish a methodology for rapid tracking of all possible contacts and elimination-based identification of the precise modes of transmission.

Achalasia is very uncommon in children, and cases accompanied with alacrima and adrenal insufficiency is even more uncommon. When these three disorders are seen altogether, it is called triple A syndrome. It is inherited in an autosomal recessive manner and has potentially life-threatening sequelae. So, pediatricians should always consider the possibility of triple A syndrome when seeing children with achalasia. Neurological abnormalities such as autonomic neuropathy, peripheral neuropathy, sensory impairment and mental retardation occasionally accompany. We report a 2-year-old girl who presented with repeated vomiting, short stature and alacrima. Diagnosis of achalasia was made after perfoming esophagogram and endoscopy and was confirmed with esophageal manometry. After pneumatic dilatation, she became asymptomatic.

PURPOSE: Retinoic acid (RA) is well known as a potent teratogenic agent in both deficiency and excess. Cellular retinoic acid binding proteins (CRABPs) are involved in RA. We carried this study in order to determine the possible relations of CRABPs with RA-induced teratogenesis through observation of the expression patterns of CRABP l and ll in developing rats. METHODS: 35S-labeled RNA probes were synthesized using SP6-RNA polymerase in CRABP l and T7-polymerase in CRABP ll. The distribution of CRABP l and ll transcripts analyzed by in situ hybridization of rat embryosections from day 12 to 19, and postnatal brains from day 1 to 14. RESULTS: The CRABP ll transcripts were more widely distributed than CRABPl distribution, however, the relative level of CRABPl transcripts were higher than CRABP ll. The CRABP l mRNA transcripts showed its highest expression on the 16th day of gestation and these distribution correlated well with structures known to be targets of RA-induced teratogenesis. CRABP ll transcripts were expressed in brain vesicle, spinal cord, head, face, tongue and genital tubercle and also found in the structures which are not involved in RA-induced teratogenesis. CONCLUSION: These results suggest the possible involvement of both CRABPs in the RA-induced teratogenesis. However, CRABP l may have more specific roles than CRABP ll which may play a role through a different mechanism.

BACKGROUND AND OBJECTIVES: Globus pharyngeus is the feeling of a lump or foreign body in the throat. Otolaryngologists are often confronted with this condition, and some authors report that it represents 3 percent of all new clinic referrals. Unfortunately, we still do not completely understand the etiologies of globus pharyngeus, but there are recently increasing evidences to link the globus symptoms with various diseases. MATERIAL AND METHODS: We selected 32 globus patients, who exhibited no pathologic condition in physical examinations, and were analysed by general work up, barium esophagogram, 24 hour-ambulatory double-probe pH monitoring, esophageal manometry test, Fuchs' series, and MMPI. RESULTS: The results were as follows, gastroesophago-laryngopharyngeal reflux disease (n=15: 46.9%), various psychotic problems (n=11: 34.4%), esophageal motility disorders (n=7: 21.9%), duodenal ulcer (n=2: 6.3%), Eagle's syndrome (n=2: 6.3%), and hiatal hernia (n=1: 3.1%). In 5 cases, we couldn't find the etiology of globus pharyngeus. CONCLUSION: Globus pharyngeus patients, who had no pathologic findings in layrnx and pharynx, might have laryngopharyngeal-gastroesophageal reflux diseases and psychologic problems.

Gastric stump cancer is defined as cancers that develop in the gastric remnant after the gastric resection of nonmalignant lesions or malignant lesions. The interval between gastrectomy and the detection of gastric stump cancer must be over 5 years in nonmaligant lesions and 10 years in malignant lesions. Symptoms of gastric stump cancer are not specific, so, diagnosis is often delayed. Early detection and curative operation is very important in gasric stump cancer and follow-up endoscopic examination is the most importaint diagnostic tool to detect gastric stump cancer. Recently we experienced a case of early gastric stump cancer. We report review of the literature to remind the important of gastric stump cancer and the important of follow-up endoscopic examination.

OBJECTIVES: Laryngomicrosurgery (LMS) is used to manage most vocal fold lesions. However, the functional voice outcome of the LMS might be diverse due to the influence of various factors. We intend to evaluate the incidence and etiologic factors of persistent dysphonia after LMS for benign vocal fold disease (BVFD). METHODS: We performed a retrospective review of 755 patients who underwent LMS for BVFD. We analyzed the clinical characteristics, preoperative and postoperative two onths voice studies. Postsurgical dysphonia was defined as grade 1 or above in GRBAS (grade, roughness, breathiness, asthenia, and strain) scale. Thirty nine patients (5.2%; 25 males and 14 females; average, 42.9 years; range, 21 to 70 years) were diagnosed with postsurgical dysphonia. RESULTS: There was no correlation between the diagnosis, coexistence with laryngopharyngeal reflux disease, habit of smoking, or occupational voice abuse and voice outcome. The patients with a worse preoperative acoustic parameter had aworse voice outcome. Stroboscopic findings showed excessive scarring or bowing in 21 cases, presence of lesion remnant in eight cases, prolonged laryngeal edema in five and no abnormal findings in three. CONCLUSION: Great care should be taken in patients with worse preoperative jitter. With a few exceptions, postoperative dysphonia can be avoided by the use of an ppropriate surgical technique.
