Chronic cough in children is an increasingly important public health issue. It typically involves diseases related to the upper respiratory tract, lower respiratory tract, and reflux. Due to its often multifactorial nature, the diagnosis and treatment of chronic cough present significant challenges, necessitating multidisciplinary collaboration among otolaryngology, pulmonology, and gastroenterology. This article aims to review the unique role of otolaryngology in the diagnosis and treatment of conditions associated with chronic cough in children.

Objective:To obtain a prevalent respiratory syncytial virus (RSV) clinical isolate in Beijing and analyze the genotype and biological characteristics of the strain.Methods:A nasopharyngeal secretion specimen was collected from a child with RSV infection in Beijing in 2023 and used for viral isolation. Viral nucleic acid was amplified using qRT-PCR. The isolated virus was identified by transmission electron microscopy, indirect immunofluorescence assay, and plaque formation assay. A phylogenetic analysis was conducted based on the whole-genome sequencing results. Virus titers were determined, and replication characteristics were analyzed. The efficacy of the isolated strain for in vitro screening of antiviral drugs was validated. Results:A clinical RSV isolate, named hRSV/C-Tan/BJ 202301, was successfully isolated, which could form syncytia in Hep-2 cells. Spherical, filamentous, and irregular virus particles were observed by electron microscopy. Immunofluorescence detection showed green fluorescence in Hep-2 cells, and plaque assay showed round plaques, which were similar to the Long strain in morphology. Genomic sequence analysis showed that it belonged to ON1 genotype. It exhibited similar cell growth kinetics characteristics with the Long strain and could be used for antiviral drug screening in vitro. Conclusions:In this study, one RSV strain is successfully isolated and identified. The biological characteristics and the phylogenetic relationship of this strain reflect the characteristics of the circulating strains in Beijing, which provides experimental material for RSV vaccine development and antiviral drug screening in China.

The incidence of pediatric otomycosis is gradually increasing, with a widespread prevalence of multidrug-resistant Candida auris.However, its early diagnosis remains challenging, leading to misdiagnosis and underdiagnosis.This review aims to provide a comprehensive overview of pediatric otomycosis based on relevant domestic and international studies.This article reviewed the epidemiology, etiology, risk factors, pathogenic microorganisms, diagnosis, and treatment of pediatric otomycosis, aiming to enhance the understanding of pediatric otomycosis among healthcare professionals.

Objective:To investigate the efficacy and safety of camrelizumab combined with stereotactic body radiation therapy (SBRT) in the treatment of advanced oligometastaticnon-small cell lung cancer (NSCLC).Methods:Eighty-six patients with advanced oligometastatic NSCLC who met the inclusion and exclusion criteria from March 2020 to August 2021 in the Second People′s Hospital of Yibin were divided into the control group (43 cases) and the treatment group (43 cases) according to the random number table method, the control group was given camrelizumab combined with conventional radiotherapy, and the treatment group was given camrelizumab combined with SBRT. After 8 weeks of treatment, the efficacy of the two groups was evaluated, the occurrence of side effects in the two groups was counted, the serum tumor markers [carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCC-Ag), cytokeratin 19 fragment anti-21-1 (CYFRA21-1)] levels were detected.Results:The objective effective rate of the treatment group was significantly higher than that of the control group:: 72.09% (31/43) vs. 51.16%(22/43), the difference was statistically significant ( P<0.05); the incidence of radiation pneumonia in the treatment group was significantly lower than that in the control group: 4.65% (2/43) vs. 18.60% (8/43), the difference was statistically significant ( P<0.05), and there was no significant difference in the incidences of other side effects such as cutaneous capillary endothelial proliferation (CCEP), liver damage, hypothyroidism, and radiation esophagitisbetween the treatment group and the control group ( P>0.05); the levels of serum CEA, SCC-Ag, CYFRA21-1after treatmentin the two groups were significantly lower than those before treatment, treatment group: treatmentgroup: (8.81 ± 4.82) ng/L vs. (81.67 ± 50.88) ng/L, (1.13 ± 0.55) ng/L vs. (1.56 ± 1.03) ng/L and (2.92 ± 0.99) ng/L vs. (4.63 ± 1.39) ng/L, controlgroup: (30.49 ± 19.44) ng/L vs. (89.91 ± 50.10) ng/L, (1.56 ± 1.23) ng/L vs. (1.86 ± 1.33) ng/L and (4.01 ± 2.10) ng/L vs. (5.03 ± 3.44) ng/L. and the levels after treatment in the treatment group were significantly lower than those in the control group, and there were statistical differences ( P<0.05). Conclusions:Camrelizumab combined with SBRT treatment for patients with advanced oligometastatic NSCLC can effectively reduce the levels of serum CEA, SCC-Ag, CYFRA21-1, and significantly improve the short-term efficacy, with relatively low incidence of toxic side effects.

Objective: To investigate the surgical outcomes and prognosis of spinal cord anaplastic astrocytoma (AA). Methods: A total of 27 consecutive patients diagnosed as spinal cord AA between January 2008 and May 2015 in Department of Neurosurgery of Beijing Tiantan Hospital were retrospectively reviewed. There were 18 males and 9 females, the mean age was (30.7±13.0) years (ranging from 5 to 52 years). The lesions were located at cervical level in 8 patients, at thoracic level in 9 patients, at cervicothoracic level in 3 patients, and at thoracolumbar level in 7 patients, the average number of vertebral was 3.3±1.3.The median time from onset of symptom to surgery was 4 months, ranging from 3 days to 48 months. The clinical presentations were weakness (23 cases), paresthesia (22 cases), pain (20 cases), sphincter disorder (15 cases) and paralysis (7 cases). The preoperative modified McCormick scale was as follows: grade Ⅱ for 6 cases, grade Ⅲ for 7 cases, grade Ⅳ for 7 cases, grade Ⅴ for 7 cases. The tumors were surgically removed via posterior median approach with the monitoring of the somatosensory-evoked potentials to minimize the neurological injury. All of the patients were recommonded to receive adjuvant chemotherapy and radiotherapy postoperatively after pothological verified and followed up by clinic interview or telephone postoperatively. Log-rank test was used to calculate the survival rate. Results: Gross total resection and subtotal resection were achieved in 18 patients and partial resection in 9. Twenty patients received adjuvant chemotherapy and (or) radiotherapy, 7 patients did not received chemoradiation postoperatively. Nineteen patients died and 8 were alive at the last follow-up. The median survival time was 23 months with 1 and 2-year survival rates of 85.2% and 50.0%.There was no statistical significance between subtotal resection group and partial resection group(χ²=0.089, P=0.880), the survival rates of patients in chemotherapy group and radiotherapy group were increased significantly(χ²=6.687, P=0.001; χ²=14.887, P=0.002). Conclusions Spinal cord AA is a rare spinal high-grade astrocytoma with aggressive nature, the prognosis remains poor even after comprehensive treatments. Microsurgery followed by adjuvant chemoradiation is recommended for the treatment.

OBJECTIVETo investigate the clinical features, diagnostic and therapeutic strategy of primary intraspinal melanocytoma.

METHODThe clinical data of primary intraspinal melanocytoma patients who underwent surgical operations from June 2011 to December 2014 in Department of Neurosurgery, Beijing Tiantan Hospital, Capital Medical University were retrospectively reviewed.

RESULTSSix cases of intraspinal melanocytoma, identified with pathology were collected, including 5 male and 1 female patients with the average age of 39.8 years (range 23-50 years). Limbs anesthesia and weakness were present in 2 cases. Neck and back pain were present in 4 cases. All patients performed MRI examination before operation, and only 1 case was diagnosed as primary melanocytoma, and the others were confirmed by postoperative pathology. All cases were confirmed by the pathological examination. Total resection was achieved in 2 cases, subtotal resection was achieved in 2 cases, 2 disseminated cases only achieved partial resection. The average period of postoperative follow-up process was 25.7 months(range 9-52 months). One case recurred in 9 months after surgery and died in 16 months, one case recurred in 1 year after surgery, and the other 4 cases had no recurrence. The recurrenced 2 patients had been not treated with radiotherapy, 2 patients of the 4 that not recurrenced had received radiotherapy. All patients didn't receive chemotherapy. The other patients were in good condition after surgery.

CONCLUSIONSThe intraspinal primary melanocytoma is less likely to recurrence and metastasis if total resection is achieved. Diagnosis relies on pathology. Surgery is the first choice and early total resection is strongly recommend. Appropriate radiotherapy for partial resection cases can delay tumor recurrence.

The serum contents of Cu, Fe, Zn, Pb, Cr, Mn, Ca, Mg, and K in 360 adults from different work in Nanjing were determined by atomic absorption spectrophotometry. The data were analysed by grouped statistical treatment, and the relationships among sex, age and work time were discussed. The results showed that serum Cu, Fe, Zn, Cr, Mn, Pb, Ca, Mg, K differed greatly in the different workers. There was a perfect positive correlations between Cu, Zn, Cd, Mn, Pb, Mg and age, and a negetive correlations berween Cu, Fe, Zn, Cd, Cr, Pb, Mg and work time. The serum Cu, Zn, Ca, K in women were higher than that in men.
