Publication Metadata only Somatosensory evoked potentials as a screening tool for diagnosis of spinal pathologies in children with treatment refractory overactive bladder(SPRINGER, 2017) DAĞÇINAR, ADNAN; Thomas, David Terence; Yener, Sevim; Kalyoncu, Aybegum; Uluc, Kayihan; Bayri, Yasar; Dagcinar, Adnan; Dagli, Tolga; Tugtepe, HalilPurpose To evaluate the usefulness of somatosensory evoked potential as a screening tool for spinal pathologies in patients with treatment refractory overactive bladder. Methods This prospective study was performed between January 2011 and January 2014. Children > 5 years old with treatment refractory overactive bladder were enrolled after exclusion of anatomical and neurological causes of incontinence. All patients underwent urodynamic studies, spinal MRI, and somatosensory evoked potential (SEP). Sensitivity, specificity, PPV, and NPV were calculated for SEP. Results Thirty-one children (average age 8.3 +/- 2.9 years) were included in the study. SEP was abnormal in 13 (41.9%), and MRI was abnormal in 8 (25.8%) patients. SEP was found to have a sensitivity of 87.5%, a specificity of 73.9%, positive predictive value of 53.85%, and negative predictive value (NPV) of 94.4%. Conclusion In patients with treatment refractory OAB, SEP is an important tool for the screening of tethered cord/spinal pathologies. Our results suggest that a child with a normal SEP study in this group of patients may not require further investigation with MRI.Publication Metadata only Acute Obstructive Hydrocephalus due to a Giant Posterior Cerebral Artery Aneurysm in a Pediatric Patient(S. Karger AG, 2018) DAĞÇINAR, ADNAN; Sarica C., Tanrikulu B., Sahin Y., Daǧçlnar A., Baltacioglu F., Bayri Y.Introduction: Intracranial aneurysms are very rare in children. Although subarachnoidal hemorrhage (SAH) is by far the most common presentation of aneurysms in the majority of the pediatric case series, it is not rare for an unruptured aneurysm to present with a mass effect. Acute hydrocephalus is a common finding following aneurysmal SAH. However, this malady may develop even in the absence of SAH but secondary to direct obstruction by a giant aneurysm. This situation is extremely rare in children, with only a few known case reports in the literature. Case Report: We report the case of a 10-year-old girl who presented with signs and symptoms of acute hydrocephalus; further radiological evaluation revealed obstructive hydrocephalus and a giant posterior cerebral artery aneurysm. Following endovascular treatment of the aneurysm, hydrocephalus was completely resolved, and the patient was symptom free. Conclusion: Although they are very rare, giant intracranial aneurysms must be kept in mind during the differential diagnosis of pediatric acute hydrocephalus cases. Hydrocephalus may resolve spontaneously after the successful treatment of these aneurysms. © 2018 S. Karger AG, Basel.

METHODS USSs and UPs of patients undergoing untethering for pTCS during the period January 2008-July 2012 were evaluated preoperatively and at the postoperative third and 12th months. For analysis, patients were separated into 4 groups according to the presence of USSs: group 1, USSs preoperative positive and postoperative negative; group 2, USSs preoperative positive and postoperative positive; group 3, USSs preoperative negative and postoperative positive; group 4, USSs preoperative negative and postoperative negative. Preoperative and postoperative USSs and UPs were compared. RESULTS Forty patients (average age, 7.2 years, follow-up of 2.8 years) were included. There were 13 patients in group 1, 11 in group 2, 3 in group 3, and 13 in group 4. All patients showed improvement when preoperative and postoperative USSs and UPs were compared. There was no correlation between USSs and UPs, both preoperatively and postoperatively. USSs and UPs at the postoperative third and 12th months were similar. Patients with no USS showed the most significant improvement in UP after untethering. CONCLUSION Our study has demonstrated that untethering in patients with pTCS improves urologic symptoms and UPs. However, there is no correlation between improvement in symptoms and urodynamic findings. Urodynamic changes are similar at the postoperative third and 12th months. As the most significant improvement was seen in patients without USSs, it is important that these patients undergo urodynamic studies preoperatively and postoperatively.

METHODS A standard section from 3D photogrammetry, which represents the trigonocephalic shape, was used in this study. From the midpoint of the area of this section, half diagonals were calculated to the skull outline at 5° increments in the anterior half of the head. These half diagonals were used to create a sinusoidal curve, and the area under the sinusoidal curve (AUC) was used to represent the mathematical expression of the trigonocephalic head shape. The AUC from 0° to 180° (90° from the midline to each side) was calculated and is referred to as AUC0→180. The AUC from 60° to 120° (30° from the midline to each side) was also calculated and is referred to as AUC60→120. A total of 24 patients who underwent endoscopic strip craniectomy and 13 age- and sex-matched controls were included in the study. The AUC values obtained in patients at different time points and controls were analyzed. RESULTS The mean preoperative AUC60→120 and AUC0→180 in the patients were significantly lower than those in control individuals. The increase in both AUC60→120 and AUC0→180 values is statistically significant at the discontinuation of helmet therapy and at final follow-up. Receiver operating characteristic curve analysis indicated that AUC60→120 is a more accurate classifier than AUC0→180. CONCLUSIONS The proposed method objectively quantifies complex head shape and frontal retrusion in patients with metopic craniosynostosis and provides a quantitative measure for follow-up after surgical treatment. It avoids ionizing radiation exposurePublication Metadata only Pediatrik dev torakolumbosakral araknoid kiste bağlı kord herniasyonu olgusu(2021-10-31) OĞLİN, VOLKAN; BAYRİ, YAŞAR; DAĞÇINAR, ADNAN; ŞİMŞEK, İSMAİL; SAKAR, MUSTAFA; SÖNMEZ, ÖZCAN; Şimşek I., Oğlin V., Sönmez Ö., Sakar M., Bayri Y., Dağçinar A.Araknoid kistler; araknoid membranın altında oluşan selim, neoplazi içermeyen, içi sıvı dolu yapılardır.

Currently, the disorder remains pharmacologically intractable. Herein we report the first case in which deep brain stimulation helped to relieve dystonic storm in a patient with PKAN syndrome who had homozygous c.628 2 T > G mutation of the PANK2 gene. A 10-year-old boy with PKAN disease presented with dystonic storm and was admitted to the emergency department. Examination revealed generalized dystonia and impaired breathing due to involvement of the respiratory muscles. The patient underwent surgery for bilateral globus pallidus internus deep brain stimulation. The patient showed marked response to treatment.Publication Metadata only Intractable yawning caused by foramen magnum meningioma in a patient with neurofibromatosis type 2(2015) DAĞÇINAR, ADNAN; Bayri, Yasar; Tanrikulu, Bahattin; Bayrakli, Fatih; Koç, Demet Yalçinkaya; Dağçinar, AdnanPublication Metadata only Accessory lower limb associated with spina bifida: case report(SPRINGER, 2014) DAĞÇINAR, ADNAN; Bayri, Yasar; Tanrikulu, Bahattin; Eksi, Murat Sakir; Dagcinar, AdnanHeterotopic redundancies, such as an accessory limb associated with spina bifida, are extremely rare anomalies. There are 12 cases of accessory limb associated with spinal bifida in literature. This report aims a detailed description of the additional case and an analysis of the findings in light. A male baby was born at 40 weeks of gestation and was referred to the neurosurgery clinic with a diagnosis of accessory lower limb. On physical examination, the dorsal meningocele was located at the lumbosacral region and there was accessory lower limb on it. There was no open neural placode. The accessory limb was excised on postnatal day 3. Dysraphic appendages are rare and complicated anomalies. They should be investigated carefully, and all of the lesions must be repaired for babies' quality of life.Publication Metadata only Neural tube defect family with recessive trait linked to chromosome 9q21.12-21.31(SPRINGER, 2015) DAĞÇINAR, ADNAN; Bayri, Yasar; Soylemez, Burcak; Seker, Askin; Yuksel, Sirin; Tanrikulu, Bahattin; Unver, Olcay; Canbolat, Cagri; Sakar, Mustafa; Kardag, Ozen; Yakicier, Cengiz; Dagcinar, Adnan; Ziyal, Ibrahim; Bayrakli, FatihMeningomyelocele is one of the most common and socioeconomically, psychologically, and physically debilitating neurodevelopmental diseases. A few chromosomal locus and genes have been identified as responsible for the disease; however, clear evidence still needs to be produced. This study aimed to show evidence of a strong genetic linkage in a novel chromosomal locus in a family with this neural tube defect. We identified a neural tube defect family in eastern Turkey, where two of six offspring had operations due to thoracolumbar meningomyelocele. The parents were of a consanguineous marriage. We collected venous blood from six offspring of the family. Whole genome linkage analysis was performed in all offspring. A theoretical maximum logarithm of an odds score of 3.16 was identified on chromosome 9q21.12-21.31. This result shows a strong genetic linkage to this locus. Our results identified a novel chromosomal locus related to meningomyelocele and provide a base for further investigations toward the discovery of a new causative gene.
