Öğe Cavernous Hemangioma Presenting as a Giant Cervical Mass: A Case Report(Turkish Neurosurgical Soc, 2010) Kiymaz, Nejmi; Yilmaz, Nebi; Ozen, Suleyman; Demir, Ismail; Gudu, Burhan Oral; Kozan, AbdulbakiIntramuscular hemangiomas of the head and, neck are rare congenital vascular tumors and are sparsely reported. Hemangiomas account for approximately 7% of benign tumors and usually present as a mass that suddenly enlarges. Hemangiomas are mostly seen on the trunk and extremities, but can also appear on the head and neck region. A 10-year-old boy was referred to our clinic for puffiness and swelling on the right side of his neck. Neurological examination was normal, but we observed an advanced degree of restriction in neck movement. An MRI study showed a soft tissue mass 9x8x5 in size. The mass was totally extracted by surgical intervention and pathological analysis revealed that it was a cavernous hemangioma. The patient's neck movement returned to normal after surgery. No relapse occurred during 1-year follow-up.Öğe Isolation and identification of a fungal pathogen, Beauveria bassiana (Bals.-Criv.) Vuill. (Ascomycota: Hypocreales) from the Hatay yellow strain of silkworm, Bombyx mori L., 1758 (Lepidoptera: Bombycidae) in Turkiye(Entomological Soc Turkey, Ege Univ, 2023) Gencer, Donus; Ulasli, Basak; Can, Feza; Demir, IsmailThe Hatay yellow strain of silkworm, Bombyx mori L., 1758 (Lepidoptera: Bombycidae) which produces cocoons with an extraordinary yellow color range, is one of the most important endemic and endangered cultural assets in Turkiye. In this study, intense fungal infection and many deaths were detected in the breeding trays in the Hatay yellow breed production facility. An entomopathogenic fungus was isolated from Hatay yellow strain cadavers collected in 2020. According to the morphological and molecular analysis results of the isolate, which was brought into pure culture, it was identified as Beauveria bassiana (Bals.-Criv.) Vuill. (Ascomycota: Hypocreales), the isolate HS1. Phylogenetic analysis results showed that the HS1 strain was very similar (99 %) to the isolates of B. bassiana KJ6 (Iran) and ARSEF 300 (Europe). The concentration-response test using 1 x 104-8 conidia/ml concentrations produced LC50 values of the new strain of 1.2 x 103 and 0.6 x 106 conidia/ml within 7 days against the larvae of Hatay yellow strain and hybrid strain of silkworm, respectively. The results indicated that the virulence of the B. bassiana HS1 strain to the Hatay yellow strain was much more severe and that the Hatay yellow strain had to fight it to survive.Öğe Metastatic Myxoid Liposarcoma of the Scalp: Case Report(Ortadogu Ad Pres & Publ Co, 2012) Kiymaz, Nejmi; Yilmaz, Nebi; Gudu, Burhan Oral; Demir, Ismail; Gokalp, AbdulsematLiposarcomas are the second most frequent soft tissue sarcomas occurring in adults after malignant fibrous histiocytomas; however, liposarcomas rarely occur on the scalp. A mass was detected on the hairy skin of a 38-year-old male patient who had undergone surgery for a mass on the posterior aspect of the right thigh and had been diagnosed with a myxoid liposarcoma 3 years earlier. The patient had undergone total bulk excision and the histopathologic examination of the mass lesion revealed liposarcoma metastasis. Chemotherapy was initiated. Relapse or metastasis did not develop during 3 years of follow-up. Here we present a patient with a myxoid liposarcoma, which metastasized from the posterior side of the right thigh to the scalp.Öğe Prognostic Factors in Patients with Occipital Encephalocele(Karger, 2010) Kiymaz, Nejmi; Yilmaz, Nebi; Demir, Ismail; Keskin, SiddikBackground: An encephalocele is a herniation of the brain and the meninges through a skull defect protruding towards the exterior. The condition is not rare when compared to spinal dysraphisms, but the worldwide incidence is not precisely known. The cases involving occipital encephaloceles which we have diagnosed in our clinic and the surgical approaches for this rare condition are presented herein. Methods: Thirty patients who were diagnosed with occipital encephaloceles and referred to our Neurosurgery Clinic at the Yuzuncu Yil University, Faculty of Medicine Research Hospital between 2000 and 2009 were enrolled in this study. The age of the patient, size of the sac, pathologies that accompanied the condition, and treatments applied were assessed. Results: In the present study, 30 patients (22 girls and 8 boys), whose ages varied between newborn and 14 months, were evaluated. The encephalocele sac was located in the occipital region in 27 patients (90%) and in the occipitocervical region in 3 patients (3%). Nine (30%) of the 30 patients died; 2 in the preoperative period, 2 in the postoperative early period (0-7 days) and 5 in the late postoperative period first week to 3 months). With the exception of the 2 patients who died preoperatively, surgery was performed on all of the patients. The mortality rate in our study was 29%. Conclusions: Our study demonstrated that factors which determine the prognosis of patients diagnosed with occipital encephaloceles include the size of the sac, the contents of the neural tissue, hydrocephaly, infections, and pathologies that accompany the condition. An occipital encephalocele is a congenital neurologic condition with an extremely high morbidity and mortality in spite of the treatments rendered pre- and postoperatively. Copyright (C) 2010 S.
