Abstract Objective The aim of this study was to evaluate the effect of bidirectional insertion on axial pullout strength of tapered run out (TRO), traditional negative profile (TNP) and positive profile (PP) pins. Study Design Cadaveric adult canine tibiae were harvested. Tapered run out pins (Group 1) were inserted unidirectionally to the desired position; bidirectionally past the desired position, then withdrawn to the desired position (Group 2); and bidirectionally as described for Group 2, repeated twice (Group 3). Traditional negative profile pins (Group 4–6) and PP pins (Group 9–11) were placed in the same manner. Tapered run out (Group 7), TNP (Group 8) and PP pins (Group 12) were driven unidirectionally such that the shaft of the pin violated the cis-cortex. A servohydraulic testing machine extracted the pins and measured axial peak pullout strength. Results Positive profile pins had significantly greater pullout strength than TRO and TNP pins placed unidirectionally to the desired position. Method of insertion had no effect on peak pullout strength of TNP pins. TRO and PP pins inserted unidirectionally to the desired position had significantly greater peak pullout strengths than insertion bidirectionally or if the shaft of the pin violated the cis-cortex. Conclusion The authors recommend that pins used for external skeletal fixation should be placed unidirectionally to the desired position with fluoroscopic guidance, intra-operative depth gauge measurements or measurements from preoperative radiographs. Repositioning pins results in loss of peak pullout strength with TRO and PP pins.

Examination and treatment results were presented for 17 patients with deforming arthrosis of the first metatarsal joint. In the 1 st group (12 patients) total arthroplasty of the first metatarsal joint was performed using Total Toe System implants. Second group included 5patients with dysplas- tic osteoarthrosis of the first metatarsal joint and iatrogenic aseptic necrosis of the head of the first metatarsal bone resulted from excessive medial resection of the head. In 3 patients from group 2 custom made implants and specially designed instruments were used. All patients from the 1 st group were examined in 3—12 months postoperatively. Joint condition showed 82points by AOFAS scale compared to 31 before surgery. In patients from the 2 nd group treatment results made up 88 points by AOFAS scale.

Introduction. In recent years human-6 herpes virus (HHV-6) has become the most commonly detected virus in peripheral blood, saliva and cerebrospinal fluid, both in asymptomatic infections and in diseases potentially associated with HHV-6. Today, no antiviral drug has been officially approved for the treatment of HHV-6. Materials and methods. 57 patients with chronic HHV-6 infection were examined (mean age 33.34 ± 1.86 years). Patients were divided into three groups for different treatment regimens: 1 group (12 patients) received therapy with Famvir; Group 2 (16 patients) received Valcite; Group 3 (29 patients) - Ingaron. All patients were determined by the number of copies of HHV-6 DNA by PCR in saliva samples before and after the therapy. Results. None of the patient groups received negative PCR results after treatment. In groups of patients after valcyte therapy and therapy with Ingaron there is a significant decrease in the number of copies of HHV-6 DNA. The severity of complaints after therapy was also analyzed. Significant therapeutic effect a month after therapy showed Ingaron, to a slightly lesser extent - Valcite. The worst result was obtained in the group of patients receiving famvir.

e15006 Background: Cisplatin, gemcitabine and paclitaxel are active chemotherapeutic agents for invasive urothelial carcinoma of the bladder (UCB). Biweekly administration of gemcitabine in combination with cisplatin (GEMCIS) or paclitaxel (GEMPAC) has been reported to have better tolerability than other schedules. Methods: Between 2009- 2011, we have treated 34 patients (median age 69 years, range 56-85) with muscle invasive UCB using gemcitabine (1500 mg/m2) in combination with cisplatin (50 mg/m2) or paclitaxel (150 mg/m2) given on days 1 and 15, every 4 weeks, for 3 cycles prior to radical cystectomy (RC) with bilateral pelvic lymph node dissection and urinary diversion. Patients deemed unsuitable for GEMCIS due to old age, frailty, multiple comorbidities or poor renal function received GEMPAC (n=9); all others received GEMCIS (n=25). Results: Clinical staging revealed T2, T3 and T4 disease in 20 (58.8 %), 8 (23.5 %) and 6 (17.6 %) patients, respectively. Patients were re-evaluated after 2 cycles with MRI or CT scans, which showed improvement in 21 (61.8 %) patients, no change in 12 (35.3 %) and progression in 1 patient (2.9%). Pathologic examination of the surgical specimens revealed T0, Tis, T2, T3 and T4 disease in 8 (23.5 %), 6 (17.6 %), 10 (29.4 %), 6 (17.6 %) and 4 (11.8 %) patients, respectively. Overall, pathologic downstaging was observed in 41.1% of patients. In the GEMCIS group, 12 patients (48%) had pT0 or pTis; in the GEMPAC group, 2 pts (22.2%) had pT0 disease. The most commonly observed toxicities are tabulated below. Conclusions: Biweekly GEMCIS or GEMPAC regimens were active and exceptionally well tolerated in the neoadjuvant setting in patients with muscle invasive UCB, producing favorable pathologic outcomes in an initial cohort of patients. To our knowledge, these data represent the first report detailing clinical results with these regimens in this setting. [Table: see text]

Aim of the study was to study lateral TRG in 43 patients with grade III vertical disocclusion of the dentition at the age of 7 to 18 years. Material and methods. Lateral telerentgenogram were used to study the angle indices SN-NL, SN-ML, NL-ML, showing the ratio of the upper and lower jaw relative to the base of the skull and relative to each other. The highest values of the SN-NL angle were observed in children of 1 group at the age of 18 years 9.0, in 2 group at the age of 18 years 9.3, in 3 group at the age of 17 years 8.9. The lowest values of the SN-NL angle were observed in children of group 1 at the age of 7, 8, 10 years 7.5, in group 2 at the age of 7 years 8.5, in group 3 at the age of 7 years 8.4. The highest values of the SN-ML angle were observed in children of group 1 at the age of 15, 16, 17, 18 years 33, in group 2 at the age of 18 years 37, in group 3 at the age of 17, 18 years 36. The lowest indices of the angle SN-ML was the children 1 age group 12 years 31 in group 2 at the age of 11 33, group 3, ages 11, 12, and 13 34. The highest values of NL-ML 34 angle were observed in children aged 17 years from group 1, in group 2 at age 17, 18 years 33, in group 3 at age 13, 14 and 18 years 30. In children of group 1 aged 7, 8, 11, 2 groups at the age of 9, 10 and 3 groups at the age of 8 years identified the least parameters of an angle NL-ML 28, 28, 27, respectively. Results. As a result of the study, it was noted that in children with vertical dysocclusion of the dentition of the third degree, the angles SN-NL, SN-ML, NL-ML have high indicators, which characterizes the vertical type of skull growth.
