Öğe A CASE OF WAARDENBURG SYNDROME AND AGANGLIONOSIS(Turkish J Pediatrics, 1992) ARITURK, E; TOSYALI, N; ARITURK, NWaardenburg's syndrome is characterized by a broad nasal root, pigmentation disturbance and congenital deafness while aganglionosis is described as the partial or complete lack of ganglion cells in the alimentary tract. This report describes a five-day-old male infant with Waardenburg's Syndrome associated with total aganglionosis of the colon, ileum and distal jejunum and draws attention to the causal relationship between these two entities.Öğe CYCLE LOADING TISSUE EXPANSION OF RAT JEJUNUM(Springer Verlag, 1994) ARITURK, E; NERGIZ, Y; GUZEL, A; AYDIN, GCycle loading was applied to 40 Sprague-Dawley rat jejunums to increase their diameters using a balloon catheter filled with saline over a 30-min period, with each load lasting 3 min at 1-min intervals. The dilations were performed using 0.2 ml saline in group I, 0.4 ml saline in group II, 0.6 ml saline in group III, and no dilation in the control group. The percentage increments of increase in external jejunal diameter were 10.52 in group I, 48.38 in group II, and 68.08 in group III. Histologic changes were reversible in groups I and II and irreversible in group III. It is suggested that cycle-loading tissue expansion could be used as an alternative method for the treatment of intestinal atresias to correct discrepancies in the caliber of gastrointestinal lumens.Öğe MEASUREMENT OF TESTICULAR VOLUME BY ULTRASONOGRAPHY(Turkish J Pediatrics, 1993) ARITURK, E; OZATES, MTwenty-five patients with scrotal hernia and hydrocele were studied. The testicular sizes of the patients were measured by using ultrasonography and the sliding caliper was used for calculations during surgery. The actual testicular volumes and those obtained by ultrasonography were not statistically different (p > 0.05). It is suggested that ultrasonography may be an alternative to orchidometers.Öğe SENSORY NERVE-ENDINGS IN THE ANAL-CANAL - INCREASING PATTERNS WITH AGE(Springer Verlag, 1993) ARITURK, E; NERGIZ, Y; AYDIN, G; DOKUCU, AI; TOSYALI, N; DEVECI, EEleven fetuses and 9 newborns were examined for sensory innervation of the anorectal area. The specimens were obtained immediately after death and were stained by the modified Gross silver impregnation method and examined with a light microscope. The perianal skin and rectal mucosa did not differ in either group. The anal canals of the fetuses had numerous thin, singly- and doubly-branched nerve endings with 1.0 to 1.5 mum axonal diameters. Paccinian-type lamellated corpuscles were few and contained 3-5 fibroblastic lamellae and had a diameter of 70-100 mum. The newborn group had more prominent subepithelial free nerve endings with 2.0 to 2.5-mum axonal diameters, mostly myelinated and with numerous Paccinian corpuscles with 8-10 lamellae and diameters of 100-150 mum. Globular endings were fewer and smaller in the fetal group. Muscle spindles were seen embedded in the external sphincter muscle bundles of both groups. We conclude that this pattern of sensory nerve endings indicates a time-dependent developmental process in the human anal canal.Öğe VESICO-DIVERTICULAR FISTULA - AN UNUSUAL PRESENTATION OF MECKEL DIVERTICULUM(Springer Verlag, 1991) ARITURK, E; AYDIN, GA vesico-diverticular fistula in a 4-year-old child is described. Histologically, the diverticulum showed normal mucosal epithelium without ectopic mucosa. The literature is reviewed and possible explanations of fistula formation are discussed.
