We performed a retrospective analysis of twenty-four consecutive hip arthroplasties (Total Hip Arthroplasty 18, Bipolar Arthroplasty 1, Cup revision 5) during which intraoperative frozen sections were analyzed to identify the occult active infection. We also reviewed the data such as laboratory findings (ESR, CRP), intraoperative culture, hip joint sonographic evaluation and permanent histologic section. Among the twenty-four patients those who received hip arthroplasties, 10 cases received revisional hip arthroplasties due to painful hip prosthesis loosening, 9 cases with infected hip prosthesis, 3 cases with infection after open reduction and internal fixation due to hip fracture and 2 cases with septic hip sequelae. Intraoperative frozen section had been obtained during staged revisional hip arthroplasties to determine the presence of active infection. We considered positive for infection if it shows more than 10 PML/HPF (Polymorphonuclear leukocyte /high power field) in at least 5 distinct microscopic fields from intraoperative tissue frozen section and postponed implantation of prosthesis. If it shows less than 5 PML/HPF, we performed revisional hip prosthesis implantation. We decided the implantation based on patient's condition, laboratory findings and intraoperative tissue conditions if it shows between 5 and 10 PML/HPF from intraoperative frozen section. At last follow up, 20 of 21 patients who had a revisional hip arthroplasties as below 10 PML/HPF from intraoperative frozen section remained free of infection (Specificity; 95%). We concluded that analysis of the intraoperative frozen sections is a reliable predictor as a guide to sepsis for the successful hip joint arthroplasties.

Open carpal tunnel release surgery has heen the gold standard method of treatment for who did not respond to conservative treatment and whose neurologic symptoms were progressive. However, open carpal tunnel release using a standard incision frequently associated with delayed return of hand function, residual scar tenderness and pillar pain. So, two new alternative methods such as endoscopic carpal tunnel release and limited incision technique have developed. To define the role of the limited two incision technique, we anaiyzed the postoperative functional results of 40 cases in 33 patients. The patients were divided in two groups. Group A was standard incision group (23 cases in 19 patients) and Group B was limited two incision group (l7 cases in 14 patients). The postoperative functional results were analyzed statistically using chi-square test at postoperative 3, 6, 9 and l2 weeks. There were no significant differences in reliet of numbness and paresthesias in both groups. There was a statistically significant difference in relief of scar tenderness and pillar pain at postoperative 3 and 6 weeks in Group B. There was no significant complication in both groups. We can conclude that the limited two incision technique of carpal tunnel release is a safe procedure which allows rapid return of hand functions with reduced incidence of scar tenderness in the early postoperative stages.

Fracture of the femoral neck occurred after internal fixation of intertrochanteric fracture of the femur is very rare and have been described previously in terms of stress fracture, stress-riser fracture, Youngs modulus fracture or iatrogenic fracture in the literature. This fracture documented about 20 cases in the English literature and usually occurred in elderly patients with osteoporosis and it always occur in the subcapital region. We report a case of subcapital stress fracture of the femur occurred after internal fixation with compression hip screw of intertrochanteric femur fracture.

We report CT and MR findings in tow cases of primary malignant melanoma of the vagina, one arising from cervicovaginal junction mimicking squamous cell carcinoma of the cervix and the other one recurring at vagina after resection. Two cases of malignant melanoma had high-attenuation on CT and high signal intensity on T1-weighted MR images and enhanced well after gadopentetate dimeglumine administration.

Atopic sensitization is a complex phenomenon that changes dynamically with age throughout childhood; its prevalence increases with age in young children. Additionally, with increasing age, the prevalence of sensitization to inhalant allergens and the prevalence of polysensitization to allergens increase. It is also well established that the development of atopic sensitization is the result of a complex interplay of genetic and environmental factors. However, there is considerable heterogeneity in the literature in terms of the effect of different environmental exposures in young children on the subsequent risk of atopic sensitization and allergic diseases. Previous studies on the relationship, in early life, between pet ownership, sex, exposure to secondhand smoke, exposure to traffic-related air pollution components, and atopic sensitization have yielded different results. Recent studies have highlighted the importance of gene-environment interactions, especially during early childhood, on the risk of subsequent atopic sensitization and allergic diseases. Therefore, pediatricians should consider the genetic and environmental determinants of atopic sensitization in infants and young children when diagnosing and treating patients with allergic diseases. Determining ways in which early exposure to these risk factors in young children may be reduced could be beneficial in preventing the likelihood of developing atopic sensitization.

Portal vein occlusion has previously been considered as a contraindication for TIPS placement. Several recent reports have suggested that placement of TIPS may be effective in patients with occluded portal veins to embolize varices and recanalize venous obstruction. We experienced a case of variceal bleeding associated with portal vein thrombosis who was successfully treated with TIPS placement. So we report the case with a brief review of literatures.

PURPOSE: Little data is currently available on the use of the impulse oscillometry system (IOS) parameter in analyzing the lung function of young children with cough-variant asthma (CVA) and classic asthma. The aims of this study were to evaluate the bronchial responsiveness between patients with CVA and those with classic asthma using dose-response slope and various cutoff values. METHODS: A methacholine challenge test and a pulmonary function test were performed in 43 children with classic asthma and 26 children with CVA using IOS, and the respiratory resistance (Rrs) and reactance (Xrs) were obtained. The bronchial responsiveness were assessed by provocative concentration causing an 80% fall from baseline in reactance at 5 Hz (PC80_Xrs5) and a 40% increase in resistance at 5 Hz (PC40_Rrs5) and calculating from the degree of dose-response slope (DRS) for airway resistance and reactance. RESULTS: There was no significant difference in base lung function between the two groups. However, the mean DRS_Xrs5 and the number who showed more than an 80% fall in reactance were significantly higher in classic asthma group than those in CVA group (P=0.040 and P=0.040, respectively). CONCLUSION: The use of DRS in oscillatory reactance at 5 Hz is useful for the differential diagnosis of classic asthma and CVA based on bronchial hyperresponsiveness.
