Auditory Brainstem Response in Children With Iron Deficiency Anemia
(2003) Çankaya, H.; Öner, A.F.; Egeli, E.; Çaksen, H.; Üner, A.; Akçay, G.
To investigate the neurosensorial influences with auditory brainstem response (ABR) in iron deficiency anemia. We recorded ABR in 33 children with iron deficiency anemia followed and in 31 healthy children (control group 1, 0-12 months, control group 2, 13-36 months, control group 3, 37-60 months) as a control group. The patients and controls were divided into three group: group I, at 12 months of age, group II, 13-36 months, and group III, 37-60 months. In all groups, composed latency time, inter-peak latency, amplitude of peaks, I-V wave amplitude ratio and waveform were evaluated and compared with control groups. In group I, I-V interpeak latency was increased compared with control group 1 (4.58 vs. 4.20 ms, p < 0.05). In group II, Wave V latency time and III-V interpeak latency were increased compared with control group 2 (6.21 ms vs. 5.63 ms. p < 0.005 and 0, 48 vs. 0.22 p < 0.005, respectively). In group III, wave I latency time was increased compared with control group 3 (1.56ms vs. 1.46 ms) (p < 0.05). We considered that increases in ABR latencies might be explained by delayed maturation of myelinisation, which requires iron, and/or by dysfunction of iron containing enzymes.
Castleman's Disease Arising in the Cervical Region: a Case Report
(2003) Yuca, K.; Kösem, M.; Çankaya, H.; Kutluhan, A.; Kiris, M.
Castleman's disease (CD) (angiofollicular lymph node hyperplasia) is a rare lymphoproliferative disease of unknown etiology. On rare occasions it is the cause of a solitary neck mass. Definitive diagnosis and treatment is possible with complete surgical resection. This report describes a case of this disorder of the hyalinovascular type as a solitary neck mass in a 35-year-old woman. The patient was treated by surgical excision.
Clinical Value of Preoperative Intraoral Ultrasonography in Tonsillectomy
(1998) Kutluhan, A.; Sakarya, M.E.; Çankaya, H.; Akkaya, S.
In this prospective study, 43 chronic tonsillitis patients underwent intraoral ultrasonography preoperatively and the width and thickness of tonsils and tonsillocarotid distances were measured. Positive correlation was obtained in postoperative measurements compared with ultrasonographic measurements of tonsils. The mean tonsillocarotid distances were 8.6 mm in the left and 8.25 mm in the right tonsillar fossa. This study showed that preoperative intraoral ultrasonography was to be help of tonsillectomy operations particularly in surgical anatomical orientation.
Comparison of the Effects of Lma Inflated With Room-Air or N 2o+o2 on the Oropharyngeal Structures
(2003) Kati, I.; Çankaya, H.; Tekin, M.; Abbasov, Ü.H.; Silay, E.
In this study, we aimed to evaluate the effects of between different gases for LMA cuff inflation cuff pressure, oropharyngeal lesions and sore throat incidence. Fifty-five ASA I-II patients that underwent general anaesthesia were divited into two groups randomly. The patients were premedicated with midazolam 0.05 mg kg-1 intravenously. Routine monitors were placed, and anaesthesia was induced with intravenous propofol and fentanyl. LMA were inserted after loss of eyelash reflex. LMA cuff inflation was achieved with appropriate volume of 50 % N2O+50 % O2 and room-air respectively in groups I and II. The intracuff pressure was measured at initial, 30th, 60th and 90th minutes during surgery. At the end of the operation, LMA was removed after spontaneous respiration began and oropharyngeal examination was carried out immediately by rigid optic telescope. One hour later, the patients were questioned postoperatively about sore throat. Cuff pressures were significantly lower in group I when compared to group II at 30th, 60th and 90th minutes except for initial cuff pressure. In group II, cuff pressure was gradually and significantly dropped during the course. In group I, there was a negative linear correlation between time and lesion and positive linear correlation between lesion and sore throat. In group II, there was a positive linear correlation between pressure and lesion, pressure and sore throat and lesion and sore throat. Sore throat was significantly more frequent in group II. In conclusion, we suggested that usage of N2O-O2 mixture instead of room-air is suitable for LMA cuff inflation because of decreased sore throat and laryngeal mucous membrane injury.
Difficult Tracheal Extubation (Case Report)
(2003) Demirel, C.B.; Kati, I.; Çankaya, H.; Hüseyinoǧlu, Ü.A.; Egeli, E.
Difficult tracheal extubation is hardly recognized by anesthesiologists as it is rarely encountered in comparison to difficult tracheal intubation. In patients, trials of extubation can be fatal when the real reason is not found. In most cases, the problem arises from an inability to deflate the cuff, commonly as a result of failure in the cuff-deflating mechanism. We present a patient who had operation for laryngo-fissur and chordectomy. The patient was intubated orally by direct laryngoscopy with a spiral endotracheal tube, which was used for the second time due to economical reasons. At the end of operation, the cuff could not be deflated via normal procedure. The patient was given anesthesia again and the cuff was exploded by a stile under direct laryngoscopy and extubation was performed. In patients with difficult tracheal extubation, it is better to do extubation after finding the real reason.
Head and Neck Granulocytic Sarcoma With Acute Myeloid Leukemia: Three Rare Cases
(Medquest Communications LLC, 2001) Çankaya, H.; Ugras, S.; Dilek, I.
We conducted a retrospective review of pathology files and hospital records and identified three unusual presentations of granulocytic sarcoma associated with acute myeloid leukemia (AML) of the head and neck. At least one mass was observed on the skin of all three patients. A 17-year-old boy had masses in each temporal region that were accompanied by bilateral facial paralysis. He was administered chemotherapy and radiotherapy, but he died of infection secondary to a second relapse 29 months after the initial diagnosis. A 17-year-old girl had a tumor in the right parotid area. She received chemotherapy, but she died of infection and bleeding 2 months after the initial diagnosis, A 33-year-old man had numerous tumors widely disseminated over his skin. He received chemotherapy and was in remission 12 months after the initial diagnosis, but he eventually relapsed and died. Granulocytic sarcoma can be localized in unexpected regions, including the head and neck. This tumor is very often misdiagnosed as a malignant lymphoma, which leads to delayed treatment and a poor outcome. Therefore, clinical and histopathologic findings should be evaluated before any diagnosis of malignant tymphoma is pronounced. Immunohistochemical stains should also be performed on patients with suspected granulocytic sarcoma, and aggressive chemotherapy or immunotherapy should be administered. We believe that high-dose chemotherapy can improve survival rates in granulocytic sarcoma associated with AML.
Larinks Tüberkülozu
(2002) Çankaya, H.; Uğraş, S.; Özbay, B.; Kutluhan, A.; Kiriş, M.
Larinks tüberkülozu giderek azalmakla birlikte halen görülmeye devam eden bir hastalıktır. Ses kısıklığı yanında ağrılı yutma güçlüğü yakınması olan olgularda da düşünülmelidir. Genellikle akciğer tüberkülozunun bir komplikasyonu olmasına karşın, bazen tek başına da görülebilmektedir. Larinks karsinomu ve diğer granülomatöz hastalıklar ile bu hastalığın ayırıcı tanısının yapılması önem arz etmektedir.
Maxillary and Temporal Fibrous Dysplasia
(Royal Belgian Soc Ear, Nose, Throat, Head & Neck Surgery, 2005) Kiroglu, A. F.; Yuca, K.; Çankaya, H.; Kutluhan, A.; Kara, T.
Maxillary and temporal fibrous dysplasia: three cases. Problems/objectives: Fibrous dysplasia (FD) is a benign, expansile lesion of bone with slow progression and unknown origin. The purpose of this report is to make physicians aware of the symptoms, methods for differential diagnosis, and treatment options. Methodology: Three cases of monostotic FD are presented; two involving the maxillary sinus, and one in temporal bone. CT scans are the definitive diagnostic and follow-up method. Surgical approaches to alleviate the symptoms, including facial deformity, are described. Results: FD went undiagnosed for three years in these patients. All three patients were relieved of the symptoms by limited surgery, and remained asymptomatic for up to two years after the surgery, with no signs of recurrence. Conclusions: Practitioners should be alert to the possibility of FD, particularly if patients develop narrowing of the ear canal, or progressive postauricular or maxillofacial enlargement. Minimal surgery to alleviate the symptoms is the treatment of choice.
Subcutaneous Dermatofibrosarcoma Protuberans in Parotid Region: Case Report
(2013) Garça, M.F.; Kösem, M.; Turan, M.; Bozan, N.; Çankaya, H.
Dermatofibrosarcoma protuberans (DFSP) is a low-grade soft tissue sarcoma (fibrosarcoma) originated from dermal and subdermal layer of the skin. But subcutaneous localization is quite rare. It is one of the rare tumors and accounts for 0.1% of all malignancies. The tumor infiltrates into the deeps in the villous and finger shape. For this reason, it is quite difficult to get surgical margins in the tumor excision and the recurrence is a problem encountered frequently. An excision or Mohs technique of micrographic surgery is suggested by leaving a surgical space up to 5 cm from the tumor margines. In this case report, a case with DFSP atypically subcutaneous localized on superficial parotis gland was presented. It should be kept in mind that probability of the microscopic spread is high in these patients and they should be followed by reminding that the disease can recur in the following long years.
The Use of Recombinant Factor Viia in a Child With Glanzmann Thrombasthenia
(2006) Bay, A.; Öner, A.F.; Çankaya, H.; Doǧan, M.
Glanzmann thrombasthenia is an autosomal recessive disorder of platelet aggregation that is characterized by a life-long bleeding tendency due to quantitative and qualitative abnormalities of the platelet membrane complex glycoprotein IIb/IIIa (Gp IIb/IIIa). Platelet transfusion is the standard treatment for severe bleeding and surgical support is necessary in these patients. However, repeated platelet transfusions can result in alloimmunization, which makes subsequent transfusions ineffective. Recombinant activated factor VIIa (rFVIIa) has recently been introduced as an alternative to platelet transfusion for treatment of bleeding episodes and to cover surgery in patients with hereditary platelet function defects. We report a 8-year-old child with Glanzmann thrombasthenia. The patient had been treated by nasal tampon placement because of epistaxis three years ago in another hospital. We detected perforation of nasal septum and deformation of nasal bone due to granulation tissue induced by forgotten nasal tampon. Forgotten tampon was removed and granulation tissue was resected. Bolus injections of rFVIIa (90 _g/kg) was given immediately before operation and three times with 2 hours intervals after the surgery. The patient was discharged from hospital without any bleeding complication or thrombocyte replacement.
