We present the case of a 7-month-old girl with the karyotype 46,XX, der(13) t(2;13)(p23;p11.2).ish der(13)(wcp2+) de novo. Painting confirmed that the additional segment on 13p was of chromosome 2 origin, resulting in trisomy 2p23 -->2pter. The child had a prominent forehead with a flat hemangioma, depressed nasal bridge, protruding tongue, posteriorly angulated ears, esotropia with poor abduction of the right eye, bilateral severe myopia (-5.5 D), retinal hypopigmentation, foveal hypoplasia, and striking left optic nerve hypoplasia. She also had pectus excavatum, a protruding abdomen with diastasis recti, generalized hypotonia, delayed fine and gross motor development, grade II reflux on the left side, and grade III-IV reflux on the right side. An EEG showed epileptiform discharges. Computed tomographic scan of the brain showed decreased white matter, but magnetic resonance imaging showed normal results.

Professor Xinfang Wang first introduced the clinical application of trans nose pharynx esophagus echocardiography (TNPEE) in 2014. Subsequently, we developed the technology. In the present study we assess the feasibility of TNPEE in the ultrasonic diagnosis.. Select patients suitable for TNPEE examination. After obtaining written consent of patients or their families, oral dacronin hydrochloride gel local anesthesia was given 10-15 min before examination. The nostrils were disinfected and then smeared with tetracaine hydrochloride gel, which acted as local anesthesia and lubrication. The probe was inserted gently through the nostrils and entered the esophagus through the nasal cavity and pharynx. TNPEE is similar to transoral esophagus echocardiography (TOEE) after the probe reaches the esophagus.. TNPEE was performed in 103 patients. Forty-five patients (43.7%) underwent the examination successfully, 46 patients (44.7%) failed because of objective reasons, 12 patients midway refused to accept the examination and cancelled the examination, accounting for 11.6%, 11 patients (12.1%) suffered from epistaxis. Of all the patients with epistaxis, 9 had taken anticoagulant drugs, accounting for 82% of the patients with epistaxis. The vital signs of all patients were stable and no serious complications occurred.. Compared with TOEE, TNPEE can cause less nausea and vomiting reaction, and patients take longer time to undergo examination, which is conducive to more detailed examination. However, TNPEE has a high requirement for the probe, and its success rate is relatively low. It is easy to cause nasal bleeding in patients, so its wide clinical application is limited.

This article discusses Down's syndrome and its effect on the child. Some common medical conditions that may necessitate a child with Down's syndrome attending hospital either as an inpatient or an outpatient are identified. These include cardiac disease, atlantoaxial instability, growth, thyroid function and eye, ear, nose and throat issues. The nurse's role in minimising the stress involved for the child and the family is discussed. Practical suggestions are offered for ways of enhancing practice and improving outcomes, specifically in the area of communicating with the child and family.

Bis(2-chloroethoxy)methane is used as a solvent and the starting agent in the production of fungicides and polysulfide polymers. Bis(2-chloroethoxy)methane was nominated for study by the National Institute of Environmental Health Sciences because of its widespread use as a starting material to produce polysulfide elastomers, and because there were no 2-year carcinogenicity studies reported in the literature. Male and female F344/N rats and B6C3F1 mice received dermal applications of bis(2-chloroethoxy)-methane in ethanol (greater than 98% pure) for 2 weeks, 3 months, or 2 years. Genetic toxicology studies were conducted in Salmonella typhimurium and Escherichia coli, rat bone marrow cells, and mouse peripheral blood erythrocytes. 2-WEEK STUDY IN RATS: Groups of five male and five female rats were dermally administered 0, 12.5, 25, 50, 100, or 200 mg bis(2-chloroethoxy)methane/kg body weight in ethanol, 5 days per week for 16 days. All rats survived to the end of the study. Mean body weights of dosed rats were similar to those of the vehicle control groups. There were no histopathologic lesions related to bis(2-chloroethoxy)methane administration. 2-WEEK STUDY IN MICE: Groups of five male and five female mice were dermally administered 0, 12.5, 25, 50, 100, or 200 mg bis(2-chloroethoxy)methane/kg body weight in ethanol, 5 days per week for 17 days. All mice survived to the end of the study. Mean body weights of dosed mice were similar to those of the vehicle control groups. There were no histopathologic lesions related to bis(2-chloroethoxy)methane administration. 3-MONTH STUDY IN RATS: Groups of 10 male and 10 female rats were dermally administered 0, 50, 100, 200, 400, or 600 mg bis(2-chloroethoxy)methane/kg body weight in ethanol, 5 days per week for 14 weeks. Additional clinical pathology groups of 10 male and 10 female rats were administered the same doses for 23 days. All core study 600 mg/kg males and females and two 400 mg/kg females died before the end of the study. The cause of death was considered to be related to the cardiotoxic effect of bis(2-chloroethoxy)methane. There were no significant differences between final mean body weights of dosed rats and those of the vehicle control groups; the mean body weight gain of 400 mg/kg males was significantly less than that of the vehicle controls. Clinical findings included prostration and ataxia in 600 mg/kg rats during the first week of the study and nasal/eye discharge, lethargy, ataxia, and abnorma. Bis(2-chloroethoxy)methane was mutagenic in S. typhimurium strains TA100 and TA1535 in the presence of exogenous metabolic activation enzymes (S9) in one study; results from a second bacterial mutagenicity test were judged to be equivocal based on responses observed in TA100 and in E. coli strain WP2 uvrA/pKM101 in the presence of S9. No mutagenicity was observed in other tester strains or in the absence of S9. Bis(2-chloroethoxy)methane did not increase the frequency of micronucleated reticulocytes in bone marrow of male F344/N rats following three daily treatments by gavage or micronucleated erythrocytes in peripheral blood of male or female mice after 3 months of dermal exposure.. Under the conditions of these 2-year dermal studies, there was no evidence of carcinogenic activity of bis(2-chloroethoxy)methane in male or female F344/N rats administered 75, 150, or 300 mg/kg. There was no evidence of carcinogenic activity of bis(2-chloroethoxy)methane in male B6C3F1 mice administered 150, 300, or 600 mg/kg or in female B6C3F1 mice administered 100, 200, or 400 mg/kg. The administration of bis(2-chloroethoxy)methane for 2 years resulted in increased incidences of nonneoplastic lesions in the nose of male and female rats, the forestomach of male rats, the heart of male and female mice, and the forestomach and skin of male mice.

The purpose of the present study was to assess breathing behavior under various nasal resistance load conditions and, in particular, to determine whether respiratory responses to added nasal resistance loads occur before the threshold perception of an added load. The participants were 40 older adults who ranged in age from 59 to 82 years. Nasal airflow and resistance were measured with the pressure-flow technique, which was modified to create calibrated resistance loads. Statistical analyses revealed a significant decrease in airflow rate and volume during load conditions both before perceptual detection and at detection of increased resistance in comparison to a "no load" condition. No differences in respiratory behaviors were found between the load condition just before perceptual detection of an increased resistance load and the load condition at detection. The present findings suggest that physiologic responses to changes in the airway environment apparently occur even before there is perceptual recognition that the environment has changed.
