RESUMEN
Objective@#To analyze the clinical features of respiratory epithelial adenomatoid hamartoma (REAH) in the nasal cavity.@*Methods@#Clinical datas of 23 patients, who were hospitalized in Department of Otorhinolaryngology Head and Neck Surgery, the Affiliated Hospital of Qingdao University, from February 2016 to February 2018 with histopathologically proved REAH in the nasal cavity were reviewed. There were 18 males and 5 females, with the age range from 16 to 71 years old. The most common area, main symptoms, surgical methods and follow-up results were analyzed.@*Results@#The most common area was olfactory cleft (21 cases), and the mainly symptom was nasal congestion (18 cases). All the patients received transnasal endoscopic surgery and had no recurrence during following-up from three months to one year.@*Conclusions@#The most common area of REAH in the nasal cavity is the olfactory cleft. Histopathological result is needed to make a definite diagnosis. Complete surgical resection is the main treatment.
RESUMEN
Syncope is one of the most common emergencies in the pediatric population,which cause serious in-fluences on the quality of life of children. With the in - depth studies on the pathogenesis mechanism,the evaluation and management level of pediatric syncope has gotten great improvement. The concept of the individualized treatment has been proposed and make the treatment of syncope in children enter a new stage.
RESUMEN
<p><b>OBJECTIVE</b>To analyze the clinical characteristics and diagnosis of three cases with infant botulism.</p><p><b>METHOD</b>Clinical data of three clinically diagnosed cases with infant botulism in May 2015 in Peking University First Hospital were retrospectively analyzed. Literature search at databases of PubMed, Wanfang, China National Knowledge Infrastructure and VIP with the key words"infant AND botulism". The date of literature retrieval was from the database founding to November 2015. The characteristics of infant botulism were summarized through review of literature.</p><p><b>RESULT</b>Three patients were infants of 4-8 months of age, and all had acute onsets of anorexia and poor response. All of them had normal psychomotor development previously, and without clear history of exposure to poisons. The main findings on physical examination were reduced muscle strength and hypotonia, dullness or disappeared pupillary light reflex, reduced facial expression, weak crying and dysphagia. Unexpectedly their states of consciousness were relatively normal. Finally, through identification and PCR genotyping of bacteria in stool, 2 cases were confirmed as Clostridium (C.) botulinum type B infection. Totally 446 reports were retrieved from foreign language literature and 52 reports from Chinese literature. More than 3,000 cases of infant botulism cases were reported in the world. Rare cases were reported in China and only 1 case was reported in 2000.</p><p><b>CONCLUSION</b>Most cases of infant botulism had no clear exposure history. The main clinical manifestations are hypotonia, cranial nerve paralysis, flaccid paralysis, but different patients may have different presentations. Detection of C. Botulinum and its toxin in stool can help to confirm the diagnosis. Infant botulism is relatively rare in China, which may be related to the insufficient understanding and inspection level of the disease. It might be underestimated in China.</p>

Syncope is one of the most common emergencies in the pediatric population.Autonomic -mediated reflex syncope,including postural tachycardia syndrome and vasovagal syncope,is the main cause.Although the clinical manifestations are similar,each subtype has its optimal treatment option.With the development of translational medicine in recent years,as well as the emergence of biomarkers,precision medicine has become possible,and will be the main direction in the future researches.
RESUMEN
Objective To evaluate the efficacy of β-blockers in treatment of postural orthostatic tachycardia syndrome( POTS) in children. Methods Clinical controlled trials were collected from a variety of medical electronic databases including PubMed(1990-2014),Excerpta Medica database(EMBASE 1990-2014),ELSEVIER(1990-2014),China National Knowledge Internet(CNKI 1990—2014) and WANFANG(1990—2014) by 2 researchers simultaneously and respectively based on same inclusion and exclusion criteria. Studies were assessed based on the Juni scale evaluation,and the Meta-analysis was conducted using the Rev-Man 5. 0 software. Results In total 8 clinical trials were included out of over 200 papers. Possible publication bias were assessed by Funnel plot analysis. Meta analy-sis of the 8 studies demonstrated that compared with the placebo group, metoprolol group showed significantly better ef-ficacy in treating children with POTS(RR=0. 37,95%CI:0. 21-0. 64,P=0. 000 5). Furthermore,these included trials were divided into different subgroups based on trial design ( randomized controlled trial/non-randomized con-trolled trial and Scored/N-scored) . Although no statistical heterogeneities were detected within each subgroups by the subgroup analysis,marked heterogeneities were found among subgroups; there was no significant difference of efficacy between metoprolol and placebos in treating POTS in non-randomized controlled trial group(RR=0. 68,95%CI:0. 45-1. 02,P=0. 06). Conclusions Low-dose metoprolol is effective in treating POTS,but the conclusion still needs to be tested by more large-scaled,multi-centered and standardized clinical randomized controlled trials.
