We report on a patient with a full monosomy 21 (FM21) prenatally diagnosed in cord fetal blood, and subsequently confirmed in other tissues. Subtle chromosomal translocations of chromosome 21, were ruled-out by FISH using both painting and 21q telomeric probes. Microsatellites analysis demonstrated the paternal origin of the single chromosome. The propositus showed at 32 weeks of gestation a severe intrauterine growth retardation and microcephaly. He was born with multiple congenital malformations, hypotonia, microcephaly, bilateral microphthalmia (more severe on the left), facial dysmorphism, agenesis of the external auditory meatus, redundant skin in the neck, narrow chest, flat scrotum, cryptorchydism, hypospadias, micropene, camptodactyly, nail hypoplasia, and abnormal palmar and plantar creases. The patient died in the first day of life. At necropsy, micrencephaly, semilobar holoprosencephaly, polimicrogyria, ocular abnormalities, skeletal anomalies, congenital heart disease, and agenesis of right kidney were also observed. To our best knowledge, this case is one of the most completely patient studied with FM21. 相似文献

Background
Hirschsprung-associated enterocolitis (HAEC) represents the primary cause of high morbidity and mortality in Hirschsprung disease (HSCR) patients. The most common surgical methods for HSCR are the Soave and Duhamel procedures. Therefore, we aimed to compare the HAEC frequency following the Soave and Duhamel procedures.Methods
Medical records were retrospectively analyzed for patients who underwent the Soave and Duhamel pull-through at Dr. Sardjito Hospital, Indonesia from 2010 to 2015. The diagnosis of HAEC was determined using a HAEC scoring system.Results
One hundred patients were involved (Soave: 52 males and 19 females vs. Duhamel: 23 males and 6 females, p = 0.62). There was significant difference in mean age at pull-through (Soave: 29.9 ± 45.2 vs. Duhamel: 50.8 ± 47.5 months, p = 0.04), whereas mean age of HSCR diagnosis and pre-operative enterocolitis frequency did not differ significantly between groups (Soave: 25.4 ± 41.0 vs. Duhamel: 43.7 ± 48.1 months, p = 0.06, and Soave: 7% vs. Duhamel: 14%, p = 0.44, respectively). The HAEC frequency after pull-through was significantly higher in the Duhamel than the Soave group (28% vs. 10%, respectively, p = 0.03). Furthermore, pre-operative enterocolitis showed a significant association with HAEC following pull-through (p = 2.0 × 10–4) and the risk of HAEC after Soave pull-through was increased in long-segment aganglionosis compared to short-segment HSCR (p = 0.015).Conclusions
The frequency of HAEC was significantly higher after the Duhamel than the Soave procedure. Moreover, patients with pre-operative enterocolitis are prone to have HAEC following pull-through.Level of evidence

BACKGROUNND/AIM: Study of the association between Epstein-Barr virus (EBV) and the tumors of the nasopharynx renders an opportunity to introduce causal treatment Already have been proven the anti-EBV (anti-Epstein-Barr nucleus antigene) antibodies in the blood serum of the patients infected with EBV, while over 91% of the patients with nasopharyngeal malignant tumors also have a detectable anti-EBV marker. The aim of this research was to determine if there were anti-EBV antibodies in the serum of the patients with the already verified nasopharyngeal malignant tumors, and, if there were, to determine the quantitative ratio to the values in the serum of the healthy controls. METHODS: The study involved 74 individuals in the period from 1994-2001 divided into four groups: group A counting 11 patients with undifferentiated carcinome of nasopharyngeal type (UCNT); group B counting 25 patients with UCNT X-ray treated at least three years before the onset of the study; group C including 28 healthy subjecets (blood donors), and the group D with 10 patients with planocellular nasopharyngeal carcinoma. Serologic diagnostics of the patients serum was performed using the techniques of Reedman and Klein for the detection of anti-EBV antibodies in the serum. RESULTS: The presence of the statistically significantly higher values of the mean geometric titer (MGT) of the anti-EBNA antibodies was determined in 36 patients with histologically verified UCNT as compared with the control groups including 10 patients with planocellular carcinomas of the nasopharynx and 28 blood donors. Presented were anti-EBNA titers with 95% confidence interval for any participants according to the Hoo clinical classification of nasopharyngeal tumors, as well as according to the fact if they had been radiotreated within the previous three years. CONCLUSION: The results of this study confirm the conclusions of the recent literature on the possible etiopathogenesis of nasopharyngeal tumors and the use of viral anti-EBNA antibodies as viral markers in the diagnostics of UCNT diseases. 相似文献

The intracellular oxidative stress has been involved in bile acid-induced cell death in hepatocytes. Nitric oxide (NO) exerts cytoprotective properties in glycochenodeoxycholic acid (GCDCA)-treated hepatocytes. The study evaluated the involvement of Ca2+ on the regulation of NO synthase (NOS)-3 expression during N-acetylcysteine (NAC) cytoprotection against GCDCA-induced cell death in hepatocytes. The regulation of Ca2+ pools (EGTA or BAPTA-AM) and NO (l-NAME or NO donor) production was assessed during NAC cytoprotection in GCDCA-treated HepG2 cells. The stimulation of Ca2+ entrance was induced by A23187 in HepG2. Cell death, Ca2+ mobilization, NOS-1, -2 and -3 expression, AP-1 activation, and NO production were evaluated. GCDCA reduced intracellular Ca2+ concentration and NOS-3 expression, and enhanced cell death in HepG2. NO donor prevented, and l-NAME enhanced, GCDCA-induced cell death. The reduction of Ca2+ entry by EGTA, but not its release from intracellular stores by BAPTA-AM, enhanced cell death in GCDCA-treated cells. The stimulation of Ca2+ entrance by A23187 reduced cell death and enhanced NOS-3 expression in GCDCA-treated HepG2 cells. The cytoprotective properties of NAC were related to the recovery of intracellular Ca2+ concentration, NOS-3 expression and NO production induced by GCDCA-treated HepG2 cells. The increase of NO production by Ca2+-dependent NOS-3 expression during NAC administration reduces cell death in GCDCA-treated hepatocytes. 相似文献

Fluorides are common ingredients in pharmaceutical products for oral hygiene due to their recognized effect in the prevention of tooth decay. In dental products, fluorides can be added in several different forms, such as sodium fluoride, sodium monofluorophosphate, tin fluoride, or in the form of different amines. This work describes potentiometric determination of fluorides in the samples of toothpastes and mouthwash. The method was optimized for the particular analytical purpose; namely, for the analysis of toothpastes and mouthwash by applying different sample preparation protocols depending on the fluoride source. Good recovery (93–103%) confirmed the correctness of the sample preparation procedures. Calculated limit of detection and limit of quantification for the optimized method were 1 × 10?3 mg/L and 2.8 × 10?3 mg/L fluoride, respectively. In the minority of the analyzed samples, calculated contents agreed well with the certified values, whereas the samples of mouthwash demonstrated better agreement. 相似文献
