Twenty flexor tendons in 13 children with a mean age of 7 years old (range from 9 months to 14 years) were treated by primary suture between 1994-1999. Both tendons were repaired in 12 (60%) digits and only FDP in 8 (40%) with excision of FDS. Mean follow-up was 19 months (from 6 to 55 months). In the 12 fingers with FDS repair, the results were excellent in 2, good in 4, fair in 3 and poor in 3. In the 8 fingers with FDS excision, 2 rated excellent, 5 good and 1 poor. In conclusion, repair of FDP alone with regional excision of FDS simplifies the operative procedure and reduces the number of tendon sutures inside the sheath.

Tomac, S

Article | 2002 | JOURNAL OF PEDIATRIC OPHTHALMOLOGY & STRABISMUS39 ( 4 ) , pp.226 - 230

Purpose: To investigate whether restoration of normal stereo acuity is possible in refractive accommodative esotropia. Methods: Twenty patients with refractive accommodative esotropia were included in the study. The cycloplegic refraction and the best corrected visual acuity of each patient were recorded. The patients were evaluated by the 4-prism-diopter test, Bagolini striated glasses, the Worth 4-dot test, the TNO stereo test, and the stereo fly plate of the Titmus test. Results: Eight patients had orthotropia with normal retinal correspondence and 12 patients had a small deviation with abnormal retinal correspondence. Nine patie . . .nts (8 patients with orthotropia and 1 patient with microtropia) demonstrated a gross level of stereo acuity, whereas the others demonstrated no stereopsis. Conclusion: In patients with refractive accommodative esotropia, the prognosis is not favorable for restoration of normal stereopsis, even if orthotropia is achieved Daha fazlası Daha az

Patients with rheumatoid arthritis have reduced skeletal muscle strength measured with handgrip, hip, knee or elbow isometric muscle strength. The aim of this study was to examine the relationship between (Arthritis Impact Measurement Scales) AIMS, a health status questionnaire and handgrip strength, respiratory muscle strength, respiratory muscle endurance which are recorded as Maximum Inspiratory Pressure (MIP), Maximum Expiratory Pressure (MEP) and Maximum Voluntary Ventilation (MW). We also evaluated the relationship between AIMS and other clinical parameters. Twenty-five RA patients (17 women, 8 men) aged 25-71 participated in . . .this study. Patients had significantly reduced MIP, MEP, MVV and handgrip strength values compared to the healthy controls. Correlation analysis demonstrated statistically significant correlation between AIMS total score, AIMS dimensions and clinical parameters (duration of disease, duration of morning stiffness, Ritchie articular index, visual analogue scale, erythrocyte sedimentation rate, C-Reactive protein). Respiratory muscle strength or endurance and handgrip strength values were correlated with none of AIMS items. As a result, respiratory muscle strenth and endurance may be independent from functional andphysical status of RA patients. AIMS does not provide adequate information about respiratory muscle strength and endurance. But it is quite able to reflect the relationship between disease related clinical and laboratory values even though patients are in remission Daha fazlası Daha az

Tunçtaner K.

Article | 2002 | Silvae Genetica51 ( 02.Mar ) , pp.105 - 112

In this study, growth performances and wood properties of various willow (Salix L.) clones were investigated. 53 clones were selected from natural tree-like willow populations occuring in the Black Sea, Marmara, Trace, Central Anatolia and South-east Anatolia regions. Genetic characteristics of the willow clones and poplar clone I-214, such as diameter, height, volume, volume increment, basic density, dry matter and holocellulose production, caloric value, ash content, nitrogen and protein values were determined using the data obtained from the experiment at İzmit nursery. The values representing the genetic characteristics of the c . . .lones analysed by factor analysis and discriminant analysis were applied for grouping of the clones based on the most effective variables. Selection of the willow clones to be used for further research studies were made Daha fazlası Daha az

32 Turkish corn accessions representing different climatic, geographic and topographic areas in Turkey were identified. Genetic variation and its pattern in three corn races (pop, flint and dent) included 32 accessions were investigated using 25 morphological and agronomic traits. Vegetative, ear and kernel related traits were significantly varied both among races and accessions within races. Variance component due to races and accessions within race were statistically significant, but the variance components due to accessions were generally made up large component of total variance and ranged from 17.17% in kernel length to 82.75% . . .in tassel length. There were also strong and mostly positive correlations between studied agronomic traits as well as between agronomic traits and isoenzyme loci. These correlations were explained by the traditional farming practices and enzyme specificity with flint accessions since the enzyme systems such as Alcohol dehydrogenase (locus 1), Malate dehydrogenase enzyme (loci 2-3) and 6-phospho-gluconate dehydrogenase (locus-1) are generally considered to be the characteristics of flint corn race. Canonical discriminant function analysis with twenty-five morphological and agronomic traits revealed that first two canonical discriminant variables explained 68% of total variation among accessions. Two Canonical variables, in which kernel related traits were heavily weighted, correctly classify the three corn races - indicating that Turkish corn accessions maintained their racial characteristics with agronomic and morphological traits Daha fazlası Daha az

Foucher's first dorsal metacarpal artery flap for thumb reconstruction: Evaluation of 21 cases

Ege A. | Tuncay I. | Ercetin O.

Article | 2002 | Israel Medical Association Journal4 ( 6 ) , pp.421 - 423

Background: Coverage of part of a soft tissue defect in the thumb, without bone shortening and without long-lasting immobilization in an inappropriate position leading to stiffness, is difficult to achieve. Objectives: To report our experience using Foucher's modification of the first dorsal metacarpal artery flap for thumb reconstruction in 21 cases. Methods: Foucher's flap is based on the neurovascular structures of the first dorsal metacarpal artery flap and radial nerve-sensitive branches on the dorsum of the second metacarpal and proximal phalanx. The cause of injury was work-related in all 21 cases. The patients' mean age was . . .37 (range 17-68 years), and mean follow-up was 19 months (range 12-31). Emergency surgery was performed in 13 patients with a time delay after injury of 4-12 hours. The minimum defect was 12×18 mm and the maximum 20×40 mm. Pedicular length was 55-95 mm. A skin bridge was left intact in 16 cases. In two cases of early postoperative venous congestion and flap loss, a cross-finger flap was performed as a salvage procedure. Results: Subjective satisfaction score was 8.37/10 (range 4-10); cold intolerance was experienced in 60% and dysesthesia in 33%. All except one patient are able to use their thumb in daily activity. Loss of mobility in the proximal interphalangeal joint of the index finger was less than 20 degrees. Semmes-Weinstein sensitivity evaluation score was 3.61-4.31 on the flap and 0-6.65 on the donor site. Two-point discrimination was 10.8 mm (range 8-20). Grip strength was reduced by 15% compared to the unaffected hand (hand dominance was not taken into consideration). Rehabilitation was not consistent as almost all the patients were living in another location. Conclusions: First DMCA pedicle flap is a successful thumb reconstruction method, especially in patients not disturbed by its cosmetic appearance Daha fazlası Daha az

We have carried out an explicit closed-form determination of the inverse dielectric function for a single one-dimensional (1D) quantum wire embedded in a nonlocal 3D bulk semiconductor plasma and analyzed the coupled mode plasmon dispersion relation in the hydrodynamic model. Our analysis shows that the coupled 1D-3D plasmon is damped due to even small nonlocality of the 3D plasma. Also, there is a new nonlocal low frequency mode which does not exist for either the quantum wire or the nonlocal host in the absence of the other. © 2002 Elsevier Science Ltd. All rights reserved.

The aim of this study was to investigate the effects of different doses of iron on haematological status of breastfed infants. One hundred and thirteen infants were randomized into four groups at 5 months of age. Iron supplementation was given at doses of 1 mg/kg/day, 2 mg/kg/day, and 2 mg/kg/every other day in the first three study groups, respectively, and the last group received placebo. The hematological values, except hemoglobin, were higher in the group supplemented with iron at a dose of 2 mg/kg/day, and ferritin values were statistically higher in the group supplemented with iron at a dose of 2 mg/kg/every other day than in . . .the group supplemented with iron at a dose of 1 mg/kg/day. We suggest that intermittent iron supplementation is more effective than a daily regimen in equal dosages Daha fazlası Daha az

Adhesions are a significant problem after tendon surgery. The effects of hyaluronic acid on adhesion formation of the tendo calcaneus were investigated in this study. Twenty Wistar rats were utilized. Both tendo calcanei were incised transversely, and then repaired. Hyaluronic acid (0.2 cc) was injected into peritendinous tissue on the right side, while the same amount of normal saline was injected to the left side as a control. The animals were sacrificed 40days after the experiment. Both the right and left tendon adhesions were evaluated both macroscopically and microscopically for the presence of adhesions (grading scale 0-4). Th . . .roughout the experimental period, there was no difference in range of motion of the ankle between the two groups. Macroscopically, there were fewer adhesions in the experimental group (mean 0.6 ± 0.8) compared to the controls (mean 1.1 ± 0.2). This difference was not statistically significant (p =. 096). Histopathologically, these parameters were similar in both the experimental (mean 1.15 ± 0.98) and the control groups (mean 1.9 ± 1.25). This difference was significant (p =. 043). Hyaluronic acid may be effective for prevention of adhesions in the tendo calcaneus though this effect could not be demonstrated experimentally Daha fazlası Daha az
