Open fetal surgery for myelomeningocele - is there the learning curve at reduction mother and fetal morbidity
Open fetal surgery for myelomeningocele — is there the learning curve at reduction mother and fetal morbidity?
Objectives: We aimed to show how increased experience of a surgery team in fMMC repair influences maternal andfetal/neonatal outcomes.Material and methods: We compare perinatal results of fMMC repair in our Fetal Surgery Center (FSC) in cohort groups forthe early period (2005–2011 year; previous — PFSC, n = 46) and current period (2012–2015 year; current — CFSC, n = 74)to results of the randomized Management of Myelomeningocele Study (MOMS, 78 patients).Results: The maternal morbidity due to fMMC repair was low and there was no difference comparing CFSC to PFSC andMOMS. The frequency of iatrogenic preterm labor (iPTL) ≤ 30 weeks of gestation decreased from 34.1% in PFSC to 23.9%in CFSC. Iatrogenic preterm premature rupture of membranes (iPPROM) was a common complication after fMMC repair inall cohorts. The total reduction rate of hindbrain hernation (HH) was similar in CFSC — 90.3% and PFSC — 82.1%.Conclusions: The increasing experience of our surgery team in fMMC repair majorly decreased the risk of iPTL
Alternative technique of intrauterine myelomeningocele repair to decrease the incidence of unfavorable maternal and fetal outcomes
Objectives: The aim of the study was to determine the effectiveness of an alternative method of open fetal surgery to prevent severe unfavorable prenatal events, both for the mother and the fetus.
Material and methods: In this study, the previously published results for a cohort of 46 patients, who had undergone intrauterine myelomeningocele repair (IUMR) at our Center by 2014, constituted the retrospective control group (CG). The MOMS protocol had been applied for hysterotomy, with an automatic uterine stapling device. The study group (SG) n = 57 was assembled during a prospective observation. IUMR was performed using an alternative method of hysterotomy, with the typical opening and closure of the uterus, without automatic stapling device, as described by Moron et al. Additionally, our single-center results were compared with the post-MOMS findings of other centers: CHOP (Children’s Hospital of Philadelphia) and VUMC (Vanderbilt University Medical Center).
Results: No cases of delivery before 30 weeks of gestation (0%, 0/55) were observed in the study group, which is a statistically significant difference (p < 0.05) as compared to controls (15/44). Statistically significantly lower incidence of chorioamniotic separation (5.4% (3/55) vs CHOP 22.9% (22/96), p < 0.001) and contractile activity resulting in preterm labor (16.3% (9/55) vs CHOP 37.5% (36/96), p < 0.05) was found in the study group. Premature rupture of the membranes was statistically significantly less common in the study group as compared to controls, CHOP and VUMC (SG 12.7% (7/55) vs CG 52.2% (24/46), p < 0.001; vs CHOP 32.3% (31/96), p < 0.001; vs VUMC 22% (9/43), p < 0.01, respectively).
Conclusions: The presented IUMR method is associated with improved perinatal outcomes, i.e., lower rates of preterm delivery at < 30 weeks of gestation, preterm premature rupture of membranes, and uterine contractility resulting in preterm delivery. That, in turn, results in lower prematurity rates and, consequently, more favorable neonatal outcomes

Lesion of the Cerebellar Noradrenergic Innervation Enhances the Harmaline-Induced Tremor in Rats
Abnormal synchronous activation of the glutamatergic olivo-cerebellar pathway has been suggested to be crucial for the harmaline-induced tremor. The cerebellum receives two catecholaminergic pathways: the dopaminergic pathway arising from the ventral tegmental area/substantia nigra pars compacta, and the noradrenergic one from the locus coeruleus. The aim of the present study was to examine a contribution of the cerebellar catecholaminergic innervations to the harmaline-induced tremor in rats. Rats were injected bilaterally into the cerebellar vermis with 6-hydroxydopamine (6-OHDA; 8 μg/0.5 μl) either alone or this treatment was preceded (30 min earlier) by desipramine (15 mg/kg ip). Harmaline was administered to animals in doses of 7.5 or 15 mg/kg ip. Tremor of forelimbs was measured as a number of episodes during a 90-min observation. Rats were killed by decapitation 30 or 120 min after harmaline treatment. The levels of dopamine, noradrenaline, serotonin, and their metabolites were measured by HPLC in the cerebellum, substantia nigra, caudate–putamen, and frontal cortex. 6-OHDA injected alone enhanced the harmaline-induced tremor. Furthermore, it decreased the noradrenaline level by ca. 40–80% in the cerebellum and increased the levels of serotonin and 5-HIAA in the caudate–putamen and frontal cortex in untreated and/or harmaline-treated animals. When 6-OHDA treatment was preceded by desipramine, it decreased dopaminergic transmission in some regions of the cerebellum while inducing its compensatory activation in others. The latter lesion did not markedly influence the tremor induced by harmaline. The present study indicates that noradrenergic innervation of the cerebellum interacts with cerebral serotonergic systems and plays an inhibitory role in the harmaline-induced tremor
Fetoscopic Myelomeningocele Repair with Complete Release of the Tethered Spinal Cord Using a Three-Port Technique: Twelve-Month Follow-Up—A Case Report
Open spina bifida is one of the most common congenital defects of the central nervous system. Open fetal surgery, which is one of the available therapeutic options, remains the gold standard for prenatal repairs. Fetoscopic closure may lower the number of maternal complications associated with open fetal surgery. Regardless of the approach, the outcome may be compromised by the development of tethered spinal cord (TSC) syndrome. At 24.2 weeks of gestation, a primipara was admitted due to fetal myelomeningocele and was deemed eligible for fetoscopic repair. Fetal surgery was performed at 25.0 weeks of gestation. It was the first complete untethering of the spinal cord and anatomic reconstruction (dura mater, spinal erectors, skin) achieved during a fetoscopic repair of spina bifida. Cesarean section due to placental abruption was performed at 31.1 weeks of gestation. VP shunting, with no need for revision, was performed at 5 weeks postdelivery due to progressing ventriculomegaly. No clinical or radiological signs of secondary tethering were observed. Neurological examination at 11 months postdelivery revealed cranial nerves without any signs of damage, axial hypotonia, decreased muscle tone in the lower extremities, and absent pathological reflexes. Motor development was slightly retarded. Complete untethering of the neural structures should always be performed, regardless of the surgical approach, as it is the only course of action that lowers the risk for developing secondary TSC
Stereotyping and satisfaction with life and the desirability of control in older adults
Wraz ze wzrostem średniej długości życia starość stała się ważnym tematembadawczym ostatnich lat. Starzenie się to okres niekorzystnych zmian, które to bez badańzdają się być trwałe i nieodwracalne. Badanie tych zmian jest ważne dla przyszłejprofilaktyki i prewencji procesu starzenia się. W niniejszej pracy zaprezentowanobadania, których celem jest analiza związku między satysfakcją z życia a potrzebąkontroli i stereotypizacją u osób starszych. Każda ze zmiennych zwiąże się ze sobą, a jejpoziom może zmieniać się wraz z wiekiem. W badaniu oczekiwano, że wskaźniksatysfakcja z życia oraz stereotypizacja będą charakteryzować się wzrostem w okresiepóźnej dorosłości, natomiast potrzeba kontroli wręcz odwrotnie, wraz z wiekiem będziemalała.W badaniu uczestniczyło 60 osób, w tym jedną połowę stanowiły osoby młode adrugą starsze.

Cochlear implantation in autistic children with profound sensorineural hearing loss
Abstract Introduction Cochlear implants have become the method of choice for the treatment of severe-to-profound hearing loss in both children and adults. Its benefits are well documented in the pediatric and adult population. Also deaf children with additional needs, including autism, have been covered by this treatment. Objective The aim of this study was to assess the benefits from cochlear implantation in deafened children with autism as the only additional disability. Methods This study analyzes data of six children. The follow-up time was at least 43 months. The following data were analyzed: medical history, reaction to music and sound, Ling's six sounds test, onomatopoeic word test, reaction to spoken child's name, response to requests, questionnaire given to parents, sound processor fitting sessions and data. Results After cochlear implantation each child presented other communication skills. In some children, the symptoms of speech understanding were observed. No increased hyperactivity associated with daily use cochlear implant was observed. The study showed that in autistic children the perception is very important for a child's sense of security and makes contact with parents easier. Conclusion Our study showed that oral communication is not likely to be a realistic goal in children with cochlear implants and autism. The implantation results showed benefits that varied among those children. The traditional methods of evaluating the results of cochlear implantation in children with autism are usually insufficient to fully assess the functional benefits. These benefits should be assessed in a more comprehensive manner taking into account the limitations of communication resulting from the essence of autism. It is important that we share knowledge about these complex children with cochlear implants
Absence of a Hernia Sack in Patients Undergoing Prenatal Repair of Spina Bifida Increases the Risk of Developing Shunt-Dependent Hydrocephalus
Spina bifida aperta (SBA), with (myelomeningocele) or without (myeloschisis) a hernia sack, is the most common congenital defect of the central nervous system. Prenatal surgical closure of SBA lowers the risk for developing shunt-dependent hydrocephalus, which offers a chance at improved motor, urinary, and gastrointestinal function. A total of 96 patients who had undergone open surgery prenatal repair for SBA were analyzed. The patients were divided into two groups: Group I—12 patients (12.5%)—without a hernia sack (myeloschisis) and Group II—84 patients (87.5%)—with a hernia sack (myelomeningocele). In this study, we demonstrated that prenatal SBA repair was statistically significantly less often associated with the need for ventriculoperitoneal shunting (p > 0.00001). The shunting was statistically significantly more often required in patients from Group I (p > 0.004). The absence of a hernia sack increases the risk for developing shunt-dependent hydrocephalus in patients after prenatal SBA repair. However, as prenatal SBA repair is associated with better motor, urinary, and gastrointestinal function, increased risk of developing shunt-dependent hydrocephalus in fetuses without a hernia sack should not be treated as a contraindication to prenatal intervention
