ABSTRACT
Objective:To analyze the epidemiological characteristics of childhood infectious diseases in a single center in Beijing City from 2007 to 2021, and to provide scientific basis for the management of infectious diseases in hospitals.Methods:The clinical data of outpatients or inpatients aged<18 years old with infectious diseases recorded in the Nationwide Health Information-based Disease Control and Prevention Information System of Beijing Children′s Hospital, Capital Medical University from January 1, 2007 to December 31, 2021 were collected. Descriptive epidemiological methods were used to analyze the types of infectious diseases, population distribution, time distribution characteristics, as well as the etiological characteristics of major infectious diseases.Results:There were 219 260 cases reported, accounting for 5.73‰(219 260/38 295 800) of the total number of hospital cases, with two peaks of 25 469 and 22 928 cases in 2010 and 2019, respectively. The main category of infectious diseases was class C, accounting for 77.51%(169 947/219 260). According to the classification of transmission routes, fecal-oral transmission infectious diseases were the most common, with 144 712 cases (66.00%), followed by air and droplet transmission infectious diseases with 73 946 cases (33.73%), showing an increasing trend by year. The top five diseases in terms of incidence were hand, foot and mouth disease (114 864 cases), influenza (28 703 cases), varicella (22 190 cases), other infectious diarrheal diseases (21 040 cases) and scarlet fever (11 500 cases). Among the 219 260 children, there were 131 546 males and 87 714 females, with a male-to-female ratio of 1.5 to 1. Children aged≤6 years old comprised the majority, with a total of 189 593 cases (86.47%). The peak period of infectious diseases reporting was from May to July. Hand, foot and mouth disease was mainly caused by Coxsackie virus A16(35.02%(1 258/3 592)), while Coxsackie virus A6 had been increasing rapidly since 2017. The main pathogen of influenza was influenza A virus (62.18%(7 400/11 900)), while other infectious diarrhea was mainly caused by rotavirus (87.55%(4 283/4 892)).Conclusions:There is an intermittent outbreak in the incidence of childhood infectious diseases, and air and droplet transmission infectious diseases have shown an upward trend in recent years. Hand, foot and mouth disease, influenza, varicella, other infectious diarrheal diseases and scarlet fever are the main infectious diseases affecting children. Different diseases have the characteristics of age and onset season. The prevention and control of infectious diseases should be updated gradually according to the epidemic trend. Proper protection should be taken during peak seasons and for key populations.
ABSTRACT
OBJECTIVE: Children treated for craniopharyngioma (CP) experience significant morbidity. We aimed to investigate the clinical characteristics and postoperative complications of pediatric CP and to determine risk factors for complications to provide a theoretical basis for postoperative treatment. METHODS: In this retrospective analysis, we screened clinical data concerning children with CP who had undergone surgery at our hospital from December 2011 to June 2015. We statistically analyzed the relationship between age, sex, disease course, tumor location, extent of tumor resection, and neuroendocrine axis dysfunction. RESULTS: Of 240 patients (males, n = 144; females, n = 96; mean age, 8.33 ± 4.64 years), the main clinical presentations were headache (n = 151, 62.92%), vomiting (n = 84, 35%), vision changes (n = 101, 42.08%), polydipsia and polyuria (n = 47, 19.58%), and growth retardation (n = 42, 17.5%). Hypothalamic-pituitary dysfunction was the most common postoperative complication. There were 216 (90.00%) and 181 (75.42%) patients with pituitary-thyroid and pituitary-adrenal axis injuries, respectively. Being a prepubescent girl was a risk factor for impaired pituitary-thyroid and pituitary-adrenal axis function (P < 0.05). No correlation was found between sex (male), age, disease course, tumor location, extent of tumor resection, and impaired pituitary-thyroid and pituitary-adrenal axis function (P > 0.05). Pituitary-gonad axis injury was observed in 91 (37.92%) patients. Saddle and suprasellar region tumors were risk factors for impaired pituitary-gonad axis function (P < 0.05). No statistically significant correlation was found between sex, disease course, extent of resection, and impaired pituitary-gonad axis function (P > 0.05). CONCLUSIONS: Routine screening for complications during treatment is indicated for children with CP, to optimize the timing of interventions and reduce long-term morbidity.

Objective:To investigate the clinical features, gene mutation and follow-up outcome of children with paroxysmal kinesigenic dyskinesia(PKD).Methods:Clinical data was collected at Beijing Tiantan Hospital Affiliated to Capital Medical University from November 2018 to November 2019.In total, seven children with PKD were recruited, and peripheral blood samples for gene study were collected from six patients and their parents.Mutation analysis of PRRT2 gene was performed by PCR sequencing in children and by Sanger sequencing in patients.Results:Of the seven patients, four were male and three were female, and the median age of onset was 11 years and 6 months, ranging from 5 to 14 years.Among them, two patients were family cases and the other five patients were sporadic cases.The presentation were abnormal involuntary movements provoked by sudden movements, without loss of consciousness.Five patients exhibited dystonia and two patients had dystonia and choreoathetosis.The duration of the attacks lasted for a few seconds to 40 seconds.The frequency ranged from 5 to 15 times per day.PRRT2 mutations, c.649_650insC(P.R217PfsX8), were found in two patients with PKD families and three sporadic PKD cases.Conclusion:The onset age of PKD is pre-school or school age.The attacks manifest as dystonia or mixed with dystonia and choreoathetosis.PRRT2 is the main pathogenic gene of PKD and mutation c. 649_650insC is the hotspot mutation.Low-dose Carbamazepine has good effects.
