Evaluation of Regio Temporalis in 3 Steps in Terms of Interventional Procedures.

Regio temporalis is a site where botulinum neurotoxin is applied for various medical reasons, such as migraine, bruxism, and myofascial pain syndrome. The region is also one of the target regions in flap surgery. This study aimed to define the region topographically. In addition, it was aimed to reveal the intramuscular nerve distribution of the temporalis.11 fixed cephalus (cadaver head) and 2 fresh cephalus were used. The lateral canthus of the eye was marked as point A, and the middle of the ear tragus as point B. The transverse and vertical distances of the branching point of the superficial temporal artery to the A and B points were measured. Transverse distances of the superficial temporal artery and superficial temporal vein to A and B points were measured. The muscle was examined in 5 equal parts (L0-L1-L2-L3-L4), and each part's vertical muscle and tendon lengths were examined. Intramuscular nerve density was demonstrated by applying the modified Sihler staining to fresh temporalis'. Superficial temporal artery had an average transverse distance of 8.56±1.9 mm in women and 12.56±1.94 mm in men from the middle of the ear tragus. The artery was 64.21±5.59 mm posterior in females and 63.48±6.53 mm in males from the lateral canthus of the eye. Our study determined that the branching point of the superficial temporal artery was below the upper level of the arcus zygomaticus in 10% of cases and above it in 90% of cases. In our study, the L2 point had the highest vertical muscle length at 45.67 mm, while the L3 point had the highest vertical tendon length at 41.25 mm. The point where the muscle length had the highest ratio with 1.49 compared to the tendon length, was the L2 point. The temporalis' for which the modified Sihler staining was applied was examined in 5 quadrants. It was determined that the nerve densities were in the second and third quadrants from anterior to posterior. The distance of superficial landmarks to neurovascular structures is extremely important in interventions to the regio temporalis. Considering the average distances given in our study is important in avoiding damage in surgical procedures and not injecting into vascular structures. The point where the muscle length had the highest ratio of 1.49 compared to the tendon length was the L2 point. The area in line with this point is the most suitable area for injection. The L2 point is also the most suitable area for injection as it has the highest muscle length. Since the nerve densities were observed in the modified Sihler staining applied temporalis' 2 and 3 quadrants from anterior to posterior, botulinum neurotoxin injections to these areas will give more effective results.

First extensor compartment morphology and clinical significance: a cadaver series study.

The first extensor compartment of the wrist is a distinctly variable anatomical area. Anatomical variations in this region contribute to the pathophysiology and treatment failure of de Quervain's disease, which is a kind of tenosynovitis that develops in the first extensor compartment of the wrist. We aim to describe the first extensor compartment morphology, to evaluate the septum frequency, location of the septum, and the number of tendons of abductor pollicis longus (APL) and extensor pollicis brevis muscles (EPB). First extensor compartment of 87 wrists of 45 cadavers were dissected. The presence or absence of septum and number of tendon slips of APL and EPB revealed. The proximal and distal widths of the compartments were measured. Septums were detected in 60.9% (n=53) of the wrists. Incomplete (distal) and complete (proximal) septa were present in 35.6% (n=31) and 25.3% (n=22) of the cases. Only 26.4% of the wrists had a single slip of APL tendon. The Remaining had multiple slips. The median inner width of the proximal and distal compartments in all wrists were calculated as in the order of 9.11±1.14 mm and 8.55±1.12 mm. We believe that understanding the anatomy of the first extensor compartment in the Turkish population would be helpful to surgeons, radiologists, and physiotherapists to diagnose and manage de Quervain's disease.

Chemical Composition and Antimicrobial Activity against Phytopathogenic Fungi of Essential Oils Obtained from Echinophora tenuifolia subsp. sibthorpiana Grown in Wild and Cultivated Conditions in Turkey

The hydro-distilled essential oils obtained from aerial parts of the wild and cultivated Echinophora tenuifolia subsp. sibthorpiana have been analyzed by GC-MS and screened for antimicrobial activity. In total, 28 compounds representing more than 99% of the oils were identified. α-phellandrene (13.22% and 55.27%), δ-3-carene (49.29% and 4.03%), and methyl eugenol (22.59-25.69%) were found as the main components for the wild and cultivated oils, respectively. EOs of the wild and cultivated plants differed significantly in both the percentage of the main components and antifungal effect. α-phellandrene was more dominant in cultivated plants (55.27%) than in wild ones (13.22%), while δ-3-carene was more abundant in the wild plants (49.29%). In the antifungal assays, both oils displayed moderate to high activity against three phytopathogenic fungi; Fusarium oxysporum, Rhizoctonia solani, and Alternaria alternata.

Evaluation of Information on Body Donation Promotion at Official Websites of Turkish Anatomy Departments.

Raising public awareness of body donation is crucial for countries like Turkey that have struggling donation programs. The official websites of anatomy departments may contribute to achieving this goal. Nevertheless, previous studies reported institutional or individual reluctance of departments or anatomists, respectively, due to an expectation of adverse publicity. This study aimed to investigate whether the official websites of Turkish anatomy departments provided information on body donation and analyzed the content of these websites. Websites of anatomy departments at 100 medical faculties were evaluated. Only 12 departments (12%) provided information on body donation with varying content. A thematic analysis of the information provided revealed five main themes. These were (1) legal aspects, (2) significance, (3) acceptance/rejection criteria, (4) availability, and (5) redirection. All departments (n = 12, 100%) outlined the legal aspects of body donation, seven departments (58%) highlighted the significance of body donation, seven departments (58%) provided contact information for potential donors, five departments (41%) covered acceptance/rejection criteria, and three departments (25%) provided a link to the official website of the Turkish Society of Anatomy and Clinical Anatomy. Thus, Turkish anatomy departments were reluctant to provide information on body donation, and the content of provided information varied greatly among departments. This lack of information, coordination, and participation in existing awareness activities for body donation in anatomy department websites may be contributing to the low numbers of body donations and donor registrations seen nationally.
