The relationship between anemia and accommodative esotropia in children.

BACKGROUND: Refraction problems, motor disorders, sensorial disorders, physical and psychic traumas of eye may be responsible for development of strabismus. Anemia may cause sensory-neural disorders in children. We investigated the relationship between anemia and accommodative esotropia in children. MATERIALS AND METHODS: Sixty-four patients with accommodative esotropia were evaluated. This group was identified as patient group (group 1). Eighty-three pediatric patients, who were not esotropia and only had refraction problems, were identified as control group (group 2). The difference between the groups was statistically analyzed evaluating patients for anemia. RESULTS: 33 of 64 patients with accommodative esotropia in group 1 were male, as 43 of 83 patients with refractive error in group 2 were male. The mean age of patients in group 1 and 2 were 6 ± 3.92 and 6.37 ± 2.74 (P > 0.05) respectively. There was significant difference between two groups, when mean hemoglobin value of those was compared (P < 0.05). CONCLUSION: Hb level may affects the accommodative esotropia.

Effects of caffeic acid phenethyl ester on retinal damage after traumatic brain injury / Efectos del ester fenetílico del ácido cafeico en el daño de la retina después de una lesion cerebral traumática

SUMMARY: Head trauma damages the optic nerve visual function and visual acuity.Effects of head trauma on the retina was investigated with biochemical, histological and immunohistochemical respects.The study was conducted on 30 rats with three groups: group 1 was control group (n=10). Second group was head-traumatized group (n=10) and last group was head-traumatized+Caffeic acid phenethyl ester (CAPE, i.p. 20ml/kg/day). Upon head was traumatized, CAPE was applied to trauma+CAPE group and then for the following four days. At the end of 5th day, rats were anesthetized with ketamine hydroxide and then blood samples were taken for biochemical analysis. MDA and GSH-Px values were compared. After blood sample, total eyes of rats were dissected for histopathological and immunohistochemical analysis. In trauma group, degeneration in retinal photoreceptor cells, disintegrity and in inner and outer nuclear layers, hypertrophy in ganglion cells, and hemorrhage in blood vessels were observed. In the group treated with CAPE, lesser degeneration in photoreceptor cells, regular appearances of inner and outer nuclear layers, mild hemorrhage in blood vessels of ganglionic cell layer were observed. The apoptotic changes caused by trauma seen in photoreceptor and ganglionic cells were decreased and cellular organization was preserved due to CAPE treatment. CAPE was thought to induce healing process on traumatic damages.

RESUMEN: El trauma craneal daña la función visual del nervio óptico y la agudeza visual. Se investigaron los efectos del traumatismo craneal en la retina con aspectos bioquímicos, histológicos e inmunohistoquímicos. El estudio se realizó en 30 ratas distribuidas en tres grupos: grupo control (n = 10); grupo con traumatismo craneal (n = 10); grupo con traumatismo craneoencefálico + Éster fenetílico de ácido cafeico (CAPE, i.p. 20 ml / kg / día). Sobre la cabeza traumatizada, se aplicó CAPE a trauma + grupo CAPE durante los siguientes cuatro días. Al final del día 5, las ratas se anestesiaron con hidróxido de ketamina y luego se tomaron muestras de sangre para el análisis bioquímico. Se compararon los valores de MDA y GSH-Px. Después de la muestra de sangre, se disecaron los ojos de las ratas para su análisis histopatológico e inmunohistoquímico. En el grupo de traumatismos, se observó degeneración en las células fotorreceptoras retinianas, desintegridad en capas nucleares internas y externas, hipertrofia en células ganglionares y hemorragia en los vasos sanguíneos. En el grupo tratado con CAPE, se observó una menor degeneración en las células fotorreceptoras, apariciones regulares de capas nucleares internas y externas, hemorragia leve en los vasos sanguíneos de la capa de células ganglionares. Los cambios apoptóticos causados por el trauma visto en el fotorreceptor y las células ganglionares disminuyeron y la organización celular se conservó debido al tratamiento con CAPE. Se concluyó que CAPE induce un proceso de curación en daños traumáticos.

Continuous amnioinfusion via an epidural catheter following spontaneous membrane rupture: A case report.

Preterm premature rupture of membranes (PPROM) is seen in 3% of all pregnancies, and is a frequent cause of preterm birth, neonatal mortality and morbidity. The most important complications are maternal and foetal infection, prematurity, umbilical cord compression, hypoxia or asphyxia due to cord prolapse, pulmonary hypoplasia and extremity deformities. The basic approach to PPROM therapy aims to prevent premature birth and the development of foetal distress, and decrease the risk of maternal and foetal infection, and amniotic fluid loss. In compliance with these objectives, alternatives of PPROM therapy demonstrate a wide spectrum, including watchful waiting, amniopatch application, recurrent amnioinfusions and emergency birth. However, repeated amnioinfusions in cases of fluid loss, especially within 6 hours of therapy, provides only minimal benefit. In this case presentation, we attempted to describe a different and cost-effective continuous amnioinfusion technique performed to confer survival benefit for an immature anhydramniotic foetus affected by PPROM at the border of viability.
