- Abstract
Objective: Knowing the morphological, kinematic, and electrophysiological parameters of the smile in healthy individuals may contribute to evaluating, planning, and monitoring the smile reanimation. This study aimed to determine the correlation between 3D morphometric changes, movement kinematics, and muscle activity in the facial soft tissue of healthy individuals. Method: In this cohort study, 20 volunteers were selected from healthy individuals with no facial disorders. During smiling, three‐dimensional face scanning, facial motion capture, and surface electromyography (sEMG) were performed. The average displacement, velocity, and acceleration during facial movements were measured. The mean change in 3D surface morphometry and activation of the zygomaticus major were determined. Results: The volunteers, comprising 10 males and 10 females, had a mean age of 24 ± 10 years; for female, mean age was 23 ± 5 years and for men 26 ± 13 years. Significant correlations were found between kinematic and morphometric data (r = 0.51, p < 0.001), sEMG and morphometric (r = 0.50, p < 0.001) data, and sEMG and kinematic data (r = 0.49, p < 0.002). The maximum acceleration occurred during approximately 65% of the muscle activation time and 64% of the peak muscle activation value. Additionally, the maximum velocity was reached at around 73% of the muscle activation time and 67% of the peak muscle activation value. Furthermore, the maximum displacement values were observed at approximately 88% of the muscle activation time and 76% of the peak muscle activation value. Conclusion: The findings may provide insights into the smile's functional parameters, contribute to understanding facial muscle‐related disorders, and aid in improving the diagnosis and treatment of the smile.

Objectives: FK506 is an effective immunosuppressive drug for treating graft rejection in transplants patients. However, the neuroregenerative effect of FK506 has been well described in the literature. The aim of this study was to investigate the effects of FK506 in alpha motor neurons after primary and delayed repair of sciatic nerve.Methods: Rats (n=72) were divided into 6 groups. Control, sham-operated, primary repair FK506 (-), primary repair FK506 (+), delayed repair FK506 (-), and delayed repair FK506 (+) groups.Results: After injury, the normal structure of the motor neuron perikarya was maintained by primary repair in the FK506 (+) group. In the delayed repair group, beneficial effect of FK506 was found to be less effective. The SFI value reached -50 recovery level in the FK506-treated group earlier than those of not FK506-treated groups.Conclusion: Beneficial effect of FK506 has been approved by functional and ultrastructural data in both of primary and delayed repair groups.

Background: This report presents the case of a 68-year-old male patient with a 3-month history of progressive weakness of the left hand accompanied by symptoms of pain and dysesthesia radiating to the dorsal aspect of the forearm. Case Report: Complete compression of the radial nerve and partial entrapment of the ulnar nerve secondary to the intermuscular lipoma were detected. Electromyography findings revealed prolonged motor and sensory latency of the radial nerve and reduced sensory conduction velocity in the distribution of the ulnar nerve. The pathological findings revealed nuclear atypia with no increased mitosis, hyperchromasia, pleomorphism, or multinucleation of fat cells. Total surgical excision of the intermuscular lipoma was performed with an anterior surgical approach. Optimal functional improvement in hand extension had been achieved at a 1-year follow-up evaluation. Conclusion: Clinicians should be aware of the possibility of the entrapment of adjacent peripheral nerves by an intermuscular lipoma and its clinical and pathological manifestations.

Objectives: The nose is a critical facial feature from the cosmetic and functional point of view. The effect of size and symmetryof the nose on beauty and function is a matter of concern for surgeons. In the present study, we performed 3D analysisof nose dimensions and investigated the correlation among them.Methods: Facial mask of 40 (20 males and 20 females) young Turkish adults aged between19 and 26 years were recorded witha 3D scanner. Nose asymmetry, external nose volume, nose area, anatomical nasal index, nasal protrusion index, body height,body weight and body mass index were measured. The correlations among these measurements were investigated.Results: The external nose surface area was measured as 18.2±2.1 cm2 and external nose volume as 8.1±1.3 cm3. A significantcorrelation was found between nose asymmetry value and external nose surface area (r=0.33, p=0.03), and also between noseasymmetry value and external nose volume (p=0.34, r=0.03).Conclusion: Our study presents 3D quantitative data regarding nasal dimensions and correlation between the nose size andsymmetry.

Cerrahi gerektiren periferik sinir yaralanmalarının onarımı sonrası fonksiyonelsonuçlar genellikle yetersizdir. Çalışmamızda direk koaptasyon veya Y tüpyardımıyla yapılan HFA (HFA koaptasyon veya HFA-Y-tüp) ardından uygulananmanuel stimulasyonun (MS, haftada 5 gün 5'er dakika) aksonal yol bulma, kasreinnervasyonu ve vibrissal hareketlerin kalitesi üzerine etkisini araştırdık.Çalışmamızda doksan altı inbred dişi sıçan kullanıldı. Y tüpü (izogenik abdominalaorta) yardımıyla yapılan HFA'da n. hypoglossus'un proksimal ucu Y tüpün uzunbacağına, n. facialis'in buccal ve zygomatic dalları da tüpün kısa bacaklarınaentübüle edildi. HFA Y-tüpün ve ardından uygulanan MS'nin vibrissal motorperformans, collateral aksonal dallanmanın derecesi ve nöro-musküler kavşağıninnervasyon paterni üzerine etkileri HFA-koaptasyon (direk dikim) metoduyladördüncü ayın sonunda karşılaştırıldı.HFA-Y-tüp ile onarım metodu HFA-koaptasyonla karşılaştırıldığında, HFA-Ytüpünkollateral dallanmayı istatistiksel olarak anlamlı şekilde azalttığı belirlendi(%21'den %11'ya). Ancak nöro-musküler kavşakta poli-innervasyonuazaltamadığı ve fonksiyonel iyileşmeyi sağlayamadığı gözlemlendi. MS'ninardından HFA-koaptasyon grubunda motor son plak poliinnervasyon oranındaazalma %(24'den %17'ye) ve motor fonksiyonlarda (amplitüt: 22º'den 28º'e,açısal hızlanma: 5.180'den 11.158'e) iyileşme görülürken, HFA-Y-tüp grubundaherhangi bir değişiklik gözlenmedi.Çalışmamız sonucunda HFA-Y-tüp metoduyla yapılan onarım sonrasında aksonalyol bulmada bir artış gözlendi. Bu artış lezyon alanındaki kollateral aksonaldallanmanın azalmasıyla sağlandı. Ancak bu artışa eşlik eden fonksiyonel biriyileşme gözlenmedi. HFA-Y-tüp cerrahisi sonrası manuel stimulasyonuygulanmasının ardından da fonksiyonel bir iyileşme görülmemesi Y tüpünvibrisseal kasların poli-inervasyon paterninde iyileştirici bir etkiye sahipolmamasıyla ilişkilendirilebilir. İleriki çalışmalar morfolojik düzelmeyle birliktefonksiyonel iyileşmeye de katkı sağlayacak yeni cerrahi metotlar ve tedavilerüzerine yoğunlaşmalıdır. (transection and suture) is usually poor. To test whether manual stimulation afterdirect suture or entubulation of the hypoglossal nerve into a Y-tube conduitconnecting it with the zygomatic and buccal facial nerve branches would improveaxonal pathfinding at the lesion site, quality of muscle reinnervation and recoveryof vibrissal whisking.Ninety six young adult female inbred rats were used. For hypoglossal-facialanastomosis (HFA) over a Y-tube (HFA-Y-tube) the proximal stump of thehypoglossal nerve was entubulated and sutured into the long arm of a Y-tube(isogeneic abdominal aorta with its bifurcation). The zygomatic and buccal facialbranches were entubulated and sutured to the short arms of the Y-tube. Forhypoglossal facial coaptation the proximal stump of the hypoglossal nerve wasdirect sutured to the distal stump of facial nerve. After HFA-Y-Tube, restorationof vibrissal motor performance, degree of collateral axonal branching at the lesionsite and quality of neuro-muscular junction (NMJ) reinnervation of the manualstimulated or non stimulated animals were compared to animals receiving HFACoaptation(no entubulation) after 4 months.HFA-Y-tube reduced collateral axonal branching (from 21% to 11%). However itfailed to reduce the proportion of polyinnervated NMJ and did not improvefunctional outcome when compared to HFA-Coaptation. 57

iskemi-reperfüzyon hasarı, nitrik oksit, denervasyon - Abstract
Bu çalışmamızda iskemi reperfüzyon hasarının ve denervasyonun böbrekfonksiyonları üzerindeki etkisini ve iskemi süresindeki farklılıkların bu hasarınderecesini ne kadar etkilediğini belirlemeye çalıştık. Nitrik oksit'in (NO) hasardansonraki serum düzeylerinin farklı iskemi süreleri ve denervasyondan nasıletkilendiğini araştırdık.Otuzaltı wistar türü sıçan altışarlı altı gruba ayrıldı. Bu sıçanlardan tamamınatek böbrek modeli oluşturmak için nefrektomi uygulandı. Denerve ve innerveböbreklere 30 dk ve 60 dk süreyle klemp takıldı. Grup I (n=6) sadece sağ nefrektomiyapıldı, grup II (n=6) sağ nefrektomi ve sol renal artere klemp takılarak 30 dk iskemiuygulandı, grup III (n=6) sağ nefrektomi ve sol renal artere klemp takılarak 60 dkiskemi uygulandı, grup IV (n=6) sadece sağ nefrektomi ve sol böbreğe denervasyonuygulandı, grup V (n=6) sağ nefrektomi ve sol böbreğe denervasyon ve sol renalartere klemp takılarak 30 dk iskemi uygulandı, grupVI (n=6) sağ nefrektomi ve solböbreğe denervasyon ve sol renal artere klemp takılarak 60 dk iskemi uygulandı. Kanakımının yeniden sağlanmasından sonra 24 saatlik idrar toplandı ve kan üre azotu(BUN), kreatinin, sodyum, klor, potasyum ve nitrik oksit anlizleri için kan alındı.Böbrek fonksiyonları glomerüler filtrasyon hızı (GFR) sodyumun fraksiyonel atılımı(FeNa) ile değerlendirildi.Serum kreatinin ve BUN değerleri G-I. BUN(26±3 mg/dl)-Creatinin(0,52±0,06 mg/dl) grubu ile karşılaştırıldığında, G-II BUN(52±25 mg/dl)-Creatinin(0,8±0,3 mg/dl), G-III BUN(77±30 mg/dl)-Creatinin(1,3±0,6 mg/dl), G-VBUN(78±31 mg/dl)-Creatinin(1,2±0,6 mg/dl) ve G-VI BUN(110±29 mg/dl)-Creatinin(1,8±1 mg/dl) gruplarında anlamlı olarak yüksekti. G-III (0,5±0,4 ml/dk),G-V(0,4±0,3 ml/dk), and G-VI (0,19±0,14 ml/dk) gruplarının GFR değerleri G-I(1,4±0,5 ml/dk) grubu ile karşılaştırıldığında anlamlı bir azalma gözlenirken G-II(0,8±0,3 ml/dk) grubunda anlamlı bir farka rastlanmadı. FeNa grupV (%1,09±1,01)ve grup G-VI (%1,4±0,9) de 1'in üzerindeydi. Serum NO seviyesi G-I (336±111mmol/L) grubuyla karşılaştırıldığında G- V (520±129 mmol/L) ve G-VI (539±129mmol/L) gruplarında anlamlı olarak yüksekti.Çalışmamız sonucunda tek başına denervasyonun böbrek fonksiyonları üzerineetkisi olmadığını ve böbrek sinirlerinin böbrek üzerindeki etkisinin denervasyonlaortadan kalkmasının iskeminin oluşturduğu hasarın etkisini arttırdığınıdüşünmekteyiz. İskemi reperfüzyon hasarının süresinin uzamasıyla serum NOseviyesinin hemen bazal seviyeye dönmesinin geciktiğini gözlemledik.

Supernumerary heads of the biceps brachii muscle have been widely studied regarding their origin, insertion, size, innervation and racial differences. The most frequent variation of the biceps brachii is its supernumerary heads. During our routine dissection studies, we encountered supernumerary head of the biceps brachii muscle on two cadavers. Additionally, the supernumerary heads had abnormal attachments. We think that such variations should be kept in mind during surgical and diagnostic procedures. [ABSTRACT FROM AUTHOR]

Objective: Clinicians need accurate, reproducible, and costeffective analysis systems in analyzing movements. Although marker-based motion analysis systems have been accepted as gold-standard methods, they are difficult to access due to high costs. In addition, placing the markers is time-consuming and disadvantageous in patient comfort. With the developing technology, motion analysis systems that do not need a marker are widespread. Our study is to test the usability of Microsoft's new motion sensor in analyzing shoulder movements. Methods: In our study, we tested the dominant side shoulder flexion movements of 10 healthy individuals (5 females and five males) using the Microsoft Azure Kinect sensor. We used iPisoft 3D analysis software for the study. We calculated the range of motion of the shoulder joint Results: As a result of the analysis, we determined the range of motion during shoulder flexion to be 160±5°. Conclusion: The results we found are close to the range of motion of healthy individuals. We think Microsoft's new version sensor can be used in the shoulder range of motion. Future studies that will include more participants and different joint movements will better understand. Our study was financially supported by Akdeniz University Scientific Research Projects Unit (TSA-2020-5373). [ABSTRACT FROM AUTHOR]

Purpose: Determination of Cobb angle over radiographs or identification of the POTSI index over two dimensional photographs are the conventional methods in the diagnosis and the follow up of the scoliosis. However, evaluation of scoliosis with a noninvasive and accurate method is a matter of concern in order to eliminate the radiation exposure and to obtain reliable data. Methods: The dorsal region of five patients (2 male, 3 female) aged between 9-16 with scoliosis were scanned with a hand-held light scanner. The value of asymmetry was evaluated with comparison of two surfaces obtained from original scans and mirrored image of the scans. The root mean square (RMS) value and POTSI index was calculated. Additionally, Cobb angle was measured over radiographs. In order to test correlation among the measurements the Pearson's correlation coefficient was calculated. Results: The Cobb angle was measured as 21.38°±9.8, POTSI index was calculated as 16.75±6.9 and RMS as 6.1 ±3.5mm. A very strong significant correlation was determined between RMS and POTSI index (r=1, p=0.017). Any significant correlation was not observed either between Cobb angle and POTSI (r=-0.3, p=0.68) or RMS (r=-0.3, p=0.68). Conclusions: We can conclude that while similar results are obtained with POTSI index and RMS, Cobb angle results differ from them. The limitation of our study is the number of patients. Our results need to be confirmed with future studies on a large cohort of patients. [ABSTRACT FROM AUTHOR]
