Publication Metadata only [Accidental hypothermia (a case report)].(2006-06-30T21:00:00Z) Erkalp, Kerem; Yangin, Zehra; Başaranoğlu, Gökçen; Erden, VeyselSevere accidental hypothermia (core body temperature of less than 28 degrees C) is a life threatening state and a medical emergency associated with a high mortality rate. The prognosis depends on underlying diseases, advanced or very early age, the duration prior to treatment, the degree of hemodynamic deterioration, and especially, the methods of treatment, including active external or internal rewarming. We report a 70-year-old male patient with severe accidental hypothermia (core temperature 28 degrees C). The homeless man was found in the street. He died, in spite of all resuscitation efforts and rewarming methods. In this case report reviews the epidemiology, pathophysiology, clinical presentation, and treatment of accidental hypothermia.Publication Metadata only [An evaluation of parotid gland masses].Yaşar, Hüsamettin; Ozkul, Haluk; Verim, Ayşegül; Ilhan, Emre; Kökten, Numan; Dereci, GökçeWe retrospectively evaluated patients who underwent surgery for parotid gland masses.Publication Metadata only [Arthroscopic evaluation of the mobility of the meso-acromion].Esenyel, Cem Zeki; Demirhan, Mehmet; Duygulu, FuatFailure of fusion of the secondary centers of ossification of the acromial apophyses is a pathology that should be included in the differential diagnosis of shoulder pain and subacromial impingement syndrome. Mobility of the meso-acromion is of particular importance in choosing the appropriate treatment. This study presents a new arthroscopic method to evaluate the mobility of os acromiale.Publication Metadata only [Ectopic molar tooth in the maxillary sinus].Altun, Hüseyin; Teker, Ayşenur Meriç; Ceran, Murat; Gedikli, OrhanThe development of intranasal ectopic teeth is rare. Although they are more commonly seen in the palate and maxillary sinus, they can also be found in the mandibular condyle, coronoid process, and nasal cavity. A 30-year-old male patient presented with a complaint of headache. Computed tomography of the paranasal sinuses showed a bony mass in the right maxillary sinus wall, 1 cm in size. He did not have any history of maxillofacial trauma or operation. The mass was removed via a Caldwell-Luc procedure. It looked like a tooth. Histopathologic diagnosis was made as ectopic molar tooth. The patient was asymptomatic two weeks after the operation.Publication Metadata only [Inhibition Effect of Cell-Free Supernatants of Environmental Acanthamoeba Strains on the Viability of Metastatic Cell-Lines].(2023-03-31T21:00:00Z) Zeybek, Zuhal; Kebabcı, Çise; Bugan Gül, İlknur; Akbaş, FahriIt is known that some of the therapeutic agents against cancer cells are isolated from natural sources such as plants and animals. However, due to increasing drug resistance, studies on the discovery of new sources are needed. In this study, it was aimed to investigate the inhibition effects of four native Acanthamoeba strains on different cancer cell lines (MDA-MB-231, PC3, MAT-LyLu). 3T3 cells were used as normal cell line. All strains were recultured by using non-nutrient agar spread by heat-inactivated Escherichia coli ATCC 25922. A.castellanii ATCC 50373 was used as the standard strain. Molecular identification of the native Acanthamoeba isolates was done by polymerase chain reaction (PCR) and DNA sequence analysis using specific primer pairs (P-FLA-F, P-FLA-R, JDP-F, JDP-R). Axenic cultures of all strains were obtained in 25 cm2 tissue culture flasks and in peptone yeast extract glucose (PYG) medium. In order to investigate the effect of cell-free supernatants obtained from axenic cultures on cancer cell lines and 3T3 cell viability, MTT method was applied using different concentrations of cell-free supernatants (1%, 2%, 5%, 10%, 15%). It was determined that the viability of 3T3 cells was not affected by any Acanthamoeba cell-free supernatants (p≤ 0.05). All of the samples tested were found to have a significant inhibitory effect (p<0.05) on the viability of PC3 and MAT-LyLu cells (human and rat prostate cancer cell line). However, none of the samples had an inhibitory effect on the viability of MDA-MB-231 (breast cancer cell-line). Two native Acanthamoeba cell-free supernatants showed higher inhibitory potency (28% and 21.9%) at 2% concentration against PC3 cells compared to the reference strain (16%). Similarly, the same Acanthamoeba samples were also shown to have a better inhibition potential on the viability of MAT-LyLu cells than the reference strain. It was found that the inhibitory potential of Acanthamoeba cell-free supernatants may not be related to proteins and proteases. The results obtained from this study showed that Acanthamoeba species living in the aquatic environment isolated from our country have a potential inhibitory effect against the tested cancer cell lines. In addition to plants and animals, Acanthamoeba cell-free supernatants can also be a source for natural therapeutic substances that act against cancer cells. However, it is necessary to carry out new studies using more strains in order to detect strains with higher inhibitory effects.Publication Metadata only [Occult scapholunate ganglion in patients with dorsoradial wrist pain].Oztürk, Kahraman; Esenyel, Cem Zeki; Demir, Bilal B; Sönmez, M Mesut; Kara, Ayhan NedimThe aim of this study was to assess the results of surgical treatment of patients who had complaints of chronic wrist pain and were diagnosed as having an occult dorsal scapholunate interosseous ganglion, despite the presence of a normal x-ray and absence of trauma.Publication Metadata only [Quadriceps tendon ruptures: evaluation and treatment].Esenyel, Cem Zeki; Oztürk, Kahraman; Cetiner, Kamil; Yeşiltepe, Ridvan; Kara, Ayhan NedimWe evaluated the patients who underwent surgical repair for rupture of the quadriceps tendon.Publication Metadata only [Rupture of the triceps brachii tendon: a case report].Esenyel, Cem Zeki; Oztürk, Kahraman; Ortak, Ozgür; Kara, Ayhan NedimTriceps tendon rupture is a rare condition. A thirty-three year old man presented with a complaint of pain in his left elbow, which occurred when his motorcycle slid and flipped on one side. Physical examination two days after the accident showed swelling and ecchymosis in the elbow. There was a palpable, slightly tender defect in the triceps tendon just above the olecranon. He had normal supination and pronation. A marked weakness was noted in elbow extension as compared with the other side. A diagnosis of triceps tendon rupture was made. Radiographs revealed osteoarthrosis of the elbow joint and osteophyte formation on the top of the olecranon. Magnetic resonance scans showed a partial tear in the triceps tendon. It was repaired with large, nonabsorbable sutures passed through the holes drilled in the olecranon. The extremity was immobilized for three weeks, followed by progressive active flexion in a controlled-motion brace. Active strengthening of the triceps was begun after three months. At the end of a year, the range of motion of the elbow was full except 10 degrees loss of extension and there was no pain.Publication Metadata only [The correlation between the accuracy of steroid injections and subsequent shoulder pain and function in subacromial impingement syndrome].Esenyel, Cem Zeki; Esenyel, Meltem; Yeşiltepe, Ridvan; Ayanoğlu, Semih; Bülbül, Murat; Sirvanci, Mustafa; Kara, Ayhan NedimWe assessed the relationship between proper placement of corticosteroid injections and subsequent shoulder function and pain in subacromial impingement syndrome.
