Premedication in the pediatric population is of vital importance to reduce anxiety and facilitate anesthetic induction. Midazolam and ketamine have been used for this purpose, drugs that have shown long-term changes in neurodevelopment. Dexmedetomidine promotes a sedative, analgesic effect and lacks neurotoxic effects, its intranasal application is easy and minimally invasive. We studied the sedative and behavioral effect of intranasal dexmedetomidine 2 mcg/kg in ASA 1 and 2 children for elective surgery. They were evaluated at 10, 20 and 30 minutes of administered, in the separation of the parents and placement of the mask for inhalation induction with behavioral and sedation scores (classified from 1 to 4), we considered acceptable for admission to operating room categories 3 and 4.ResultsThirty patients between 1 and 10 years old were included in the period from September 2017 to April 2018. The sedation score obtained at 30 minutes was acceptable in 46.6% of the patients and the behavior score was in 96% of the cases. In 63% of cases the acceptance of the facial mask placement for inhalation induction was achieved. The procedure was well tolerated in all cases and parents were satisfied in 100% of the cases. 相似文献

A new mutation (Ile 436 Lys) was found in a cluster of patients in northeastern Italy. The mutation was present in five patients at the homozygote level and in one patient as a compound heterozygote with an already known mutation namely Glu 117 stop. All these patients showed a mild bleeding tendency mainly associated with deliveries or surgery. The first two patients were two sisters, and their parents were consanguineous. The third patient was the only homozygote in the family, and parents apparently were not consanguineous. The fourth and fifth patients were a brother and a sister, and in this case too, parents were not consanguineous. The sixth patient, a compound heterozygote, negated also the existence of consanguinity between his parents. There were also seven heterozygotes among the family members of the patients homozygous for this new mutation (Ile 436 Lys). Finally, there were two heterozygotes for the Glu 117 stop mutation in the family of the sixth patient. The heterozygotes, regardless of the mutation, were asymptomatic. The Ile436Lys mutation is characterized by low factor XI activity and antigen, namely is a cross-reaction material negative form. Molecular modeling indicates that the Ile436Lys mutation causes a large conformational change within the 432-442 loop. No relation could be traced among the different families; however, all their ancestors were autochthonous of the same two small towns. Furthermore, no Jewish ancestry could be found. The close geographical area in which all these patients were found and the absence of the same mutation in the general population of the area strongly suggests a founder effect and that the mutation is responsible for the defect. The compound heterozygosis with the Glu 117 stop mutation, common among Jews, was not surprising because of the past strict ties of the Republic of Venice with the Middle East. 相似文献

Summary. Twenty infertile patients with normal tubal patency were inseminated intraperitoneally (11 once, seven twice, and two three times) with spermatozoa (mean 14 times 106 , range 0.6–48 times 106 ) prepared by the standard swim-up technique. The occurrence of immunization to spermatozoa was looked for by the Gelatin Agglutination Test (GAT) and Tray Agglutination Test (TAT). Both tests gave negative results for all the controls (10 pregnant and 10 puerperal women).
Antisperm antibodies were measured in the serum before, 30 d and 4–7 months after Intraperitoneal Insemination (IPI).
The last check was done for only 14 patients, since six became pregnant as a consequence of the first treatment. Of the 14 patients studied after 4–7 months, seven had two, and two had three IPI.
In the group of inseminated patients, 18 women with no basal sperm antibody did not show evidence of antibody formation after the treatment and it was not increased after insemination in the two patients who already had low antibody titre (1/32).
In conclusion, despite the large number of spermatozoa inseminated and even after several IPI attempts, there was no evidence of de novo production of or increase in already present anti-sperm antibodies according to the methods used for the detection of ASA in this study. 相似文献

Intracortical facilitation and inhibition, as assessed by the paired-pulse transcranial magnetic stimulation technique with a subthreshold conditioning pulse followed by a suprathreshold test pulse, was studied upon awakening from REM and slow-wave sleep (SWS). Ten normal subjects were studied for four consecutive nights. Intracortical facilitation and inhibition were assessed upon awakening from SWS and REM sleep, and during a presleep baseline. Independently of sleep stage at awakening, intracortical inhibition was found at 1-3-ms interstimulus intervals and facilitation at 7-15-ms interstimulus intervals. Motor thresholds were higher in SWS awakenings, with no differences between REM awakenings and wakefulness, while motor evoked potential amplitude to unconditioned stimuli decreased upon REM awakening as compared to the other conditions. REM sleep awakenings showed a significant increase of intracortical facilitation at 10 and 15 ms, while intracortical inhibition was not affected by sleep stage at awakening. While the dissociation between motor thresholds and motor evoked potential amplitudes could be explained by the different excitability of the corticospinal system during SWS and REM sleep, the heightened cortical facilitation upon awakening from REM sleep points to a cortical motor activation during this stage. 相似文献

A multicentric retrospective study on leukemic ophthalmopathy (LO) is reported, including 38 patients (21 males, 17 females) with acute leukemia (AL) observed from 1976 to 1985. LO developed in four patients at the time of diagnosis of AL; ten were in first complete remission (eight off therapy), 12 in second remission, and 12 in combined relapse. The children were treated according to different schedules of systemic and intrathecal chemotherapy with or without radiotherapy (RT) of the affected eye. Ocular remission occurred in 32 of 38 patients, but with subsequent ocular relapse in six of the 32. Complete remission after LO treatment lasting for more than 24, 30, 40, and 78 months was observed in four of the ten children with isolated LO in first AL marrow remission. The authors concluded that systemic and intrathecal chemotherapy probably is associated with RT (at least 30 Gy to the affected eye). Aggressive treatment is justified because children with isolated ocular relapse can still be cured. 相似文献
