Item The Clinical Characteristics and Prognosis of Exon 2 Mutations in Familial Mediterranean Fever(2023) Avci, Begum; Parmaksiz, Gonul; Sahin, Feride; Noyan, Aytul; 0000-0001-7308-9673; AAC-7232-2020Objective: It is unclear whether exon 2 mutations are variations or mutations that causes the disease. This study aimed to evaluate the clinical features and prognosis exon 2 mutations in Familial Mediterranean Fever. Methods: The clinical features, disease severity and prognosis of all patients with at least one exon 2 mutations were evaluated retrospectively. These data were compared separately for homozygous (Group 1), heterozygous (Group 2), compound heterozygous (Group 3), and complex alleles (Group 4), and the data were compared by grouping patients into those with and without exon 10 mutations. Results: There were a total of 119 patients with exon 2 mutations, including 11.7% in Group 1, 36.1% in Group 2, 21.8% in Group 3, and 30.2% in Group 4 were similar in terms of demographic data, clinical characteristics, and disease course. When compared patients with exon 10 mutations (+) to those with exon 10 mutations (-), the exon 10 mutations (+) group had a higher presence of chest pain (100%, p = 0.02) and a significantly higher mean Pras severity score (6.66 +/- 1.87, 6.01 +/- 1.40; p=0.02). Additionally, a higher number of patients with exon 10 mutation (-) achieved remission with treatment (76 (67.9%), 36 (32.1%); p = 0.03). Conclusion: Exon 2 mutations have a milder course and higher remission rates but they should be considered as Familial Mediterranean Fever disease because of their similar clinical presentation and response to colchicine treatment with exon 10 mutations. Early treatment and close follow- up should be performed.Item The African Variant of BKV in A Turkish Renal Transplant Patient(2014) Colakoglu, Sule; Dursun, Hasan; Cengiz, Nurcan; Bulat, Meryem Cosar; Noyan, Aytul; https://orcid.org/0000-0002-8817-494X; 24726687; AAB-7105-2020; GPX-7059-2022; AAD-5713-2021In renal transplant recipients, BK polyomavirus (BKV) is linked to nephropathy. BK virus genotypes have a strong geographic component. This paper presents the African variant of BKV in a Turkish renal transplant patient, which is a rare cause of infection in the Northern Hemisphere and, to our knowledge, the first case from Turkey.

This manuscript reports the positive outcome of a pediatric case with a history of accidental carbamazepine intake treated using plasma exchange. A 3-year-old male presented with severe carbamazepine intoxication. He was comatose and had generalized tonic clonic seizure, ventricular tachycardia, and hypotension. Although he did not respond to classical therapies, we performed two sessions of plasma exchange. The patient recovered rapidly and was discharged from the hospital six days from the time of carbamazepine ingestion with no complication or neurologic impairment. Plasma exchange can be performed safely in very small children, and it might be the first line treatment, particularly for intoxication with drugs that have high plasma-protein-binding properties.

Ultrasound (US) observations suggest that pelvicalyceal dilatation varies according to the degree of bladder fullness in children with urinary tract infection. The aim of this study was to assess whether anterior-posterior (AP) measurements of the renal pelvis on US before and after voiding can be used as a screening tool while predicting the presence of VUR in children. MethodsThe subjects were toilet-trained children older than 4 years who required VCUG. Two groups were established based on the VCUG results: a VUR group of 40 kidney units (each unit defined as calyces and ureter) that exhibited different severities of reflux, and a control group of 68 kidney units unaffected by VUR. Prior to VCUG, US AP measurements of the renal pelvis of each kidney unit were recorded when the urinary bladder was full and again after bladder emptying. The change in AP measurement from before to after voiding was compared between the two groups. ResultsThe mean change in AP measurements from before to after voiding in the VUR group was significantly greater than that in the control group (p=0.003). ConclusionsComparing US AP measurements of the renal pelvis before and after voiding is useful for identifying children who are suspected to have VUR and thus require immediate VCUG.
