ABSTRACT
This study aims to evaluate the efficacy and safety of Compound Qinlan Oral Liquid in the treatment of acute upper respiratory tract infection. Computer-based online searching of CNKI, VIP, SinoMed, Wanfang, ChiCTR, ClinicalTrials.gov, Cochrane Library, PubMed, EMbase, and Web of Science was performed to retrieve the randomized controlled trial(RCT) regarding Compound Qinlan Oral Liquid in the treatment of acute upper respiratory tract infection. In addition, manual searching of gray literature was conducted. After two evaluators independently selected articles, extracted data, and evaluated the quality of methodology included in the studies, Meta-analysis was carried out in RevMan 5.4 and trial sequential analysis(TSA) in TSA 0.9.5.10 Beta. GRADE profiler 3.6.1 was employed to evaluate the evidence quality. A total of 21 RCTs were included in this study, involving 2 651 patients(1 330 patients in the observation group and 1 321 patients in the control group). Meta-analysis showed that compared with conventional western medicine alone, Compound Qinlan Oral liquid improved the total response rate(RR=1.15, 95%CI[1.12, 1.19], P<0.000 01) without increasing the incidence of adverse reactions(RR=0.77, 95%CI[0.47, 1.25], P=0.16). The results of subgroup analysis are described as follows:(1) Compared with conventional western medicine alone, Compound Qinlan Oral Liquid improved the total response rate(RR=1.10, 95%CI[1.05, 1.14], P<0.000 01) and shortened the time to symptom relief(SMD=-0.76, 95%CI[-1.02,-0.51], P<0.000 01). There was no significant difference in the incidence of adverse reactions between the two groups(RR=1.16, 95%CI[0.54, 2.47], P=0.71).(2) Compared with conventional western medicine alone, Compound Qinlan Oral Liquid + conventional western medicine improved the total response rate(RR=1.20, 95%CI[1.15, 1.25], P<0.000 01), decreased traditional Chinese medicine(TCM) syndrome scores(MD=-0.58, 95%CI[-0.75,-0.41], P<0.000 01), shortened the time to symptom relief(SMD=-2.44, 95%CI[-3.09,-1.80], P<0.000 01) and physical sign improvement(MD=-2.57, 95%CI[-4.11,-1.04], P=0.001), lowered the serum levels of inflammatory cytokines(SMD=-2.16, 95%CI[-2.61,-1.70], P<0.000 01), improved respiratory function indicators(SMD=1.48, 95%CI[1.00, 1.96], P<0.000 01), and enhanced the humoral immunity(MD=0.94, 95%CI[0.69, 1.18], P<0.000 01). There was no significant difference in the incidence of adverse reactions between the two groups(RR=0.57, 95%CI[0.29, 1.09], P=0.09). TSA showed that the cumulative Z curve of total response rate crossed the traditional threshold and TSA threshold, further confirming the clinical efficacy of Compound Qinlan Oral Liquid. The GRADE graded the evidence of the above outcome indicators as low or extremely low, and yielded weak recommendation. Compared with conventional western medicine alone, Compound Qinlan Oral Liquid can improve the total effective rate and reduce the time to symptom relief. The combination of Compound Qinlan Oral Liquid and conventional western medicine can improve the total response rate, mitigate the symptoms and improve the physical signs, reduce inflammation, and improve respiratory function and immunity of the patients with acute upper respiratory tract infection. In view of the limited number and quality of the included studies, the above conclusions still require high-quality RCT to provide evidence support.

Objective:To analyze the clinical and epidemiological features of human rhinovirus (HRV) infection in adult patients with upper respiratory tract infection (URTI) in Nanjing.Methods:Epidemiological data of adult patients with URTI in Nanjing from October 2021 to September 2022 were collected. Clinical specimens were collected and subjected to quantitative reverse transcription polymerase chain reaction (qRT-PCR) for the detection of 14 common respiratory viruses. The VP4/VP2 genes in HRV-positive samples were amplified and sequenced. Then a phylogenetic tree was constructed.Results:A total of 399 pharyngeal swabs were collected from patients with URTI. The overall positive rate of respiratory viruses was 28.07% (112/399) with HRV accounting for most at 9.52% (38/399). Thirty-seven VP4/VP2 sequences were successfully obtained from the 38 HRV-positive specimens. Three genotypes involving 25 serotypes were identified with 13 strains belonging to HRV-A, 14 belonging to HRV-B, and 10 belonging to HRV-C. The three genotypes of HRV showed alternate prevalence or co-prevalence.Conclusions:HRV was the main pathogen causing URTI in adult patients in Nanjing from October 2021 to September 2022, and three genotypes of HRV-A, B and C were prevalent alternatively or together.
ABSTRACT
Cholestatic jaundice is rare in patients with Graves' disease and is generally considered to be a complication of Graves' disease or an adverse reaction to methimazole. We report a case of acute cholestatic jaundice caused by Graves' disease complicated with upper respiratory tract infection in Jinan Central Hospital. After timely treatment with glucocorticoid, the jaundice quickly subsided and the liver function gradually returned to normal. We believe that Graves' disease combined with upper respiratory tract infection can lead to cholestatic jaundice, the pathogenesis of which may be immune dysfunction, and glucocorticoid therapy is beneficial to the regression of jaundice.
ABSTRACT
Background:In summer due to heat there may occur shortage of water so people try to get water from anywhere, even purification system is weak due to water shortage causing chance of water getting infected from various bacilli causing water borne diseases like Diarrhoea, Dysentery, Cholera, Typhoid etc. Some other factors like eating ice-creams, ice-gola, out-side unhygienic food, swimming in unclean swimming pool plays important role in development of acute diarrhoea. This study has been done in order to study role of Zingiber in reducing duration, intensity and frequency of summer diarrhoea. So that morbidity due to summer diarrhoea as well as general condition of the patients can be taken care of effectively, gently in a cost-effective manner. Material and Methods:This study is a prospective, clinical, interventional study .Sample of 30 cases had been selected by simple randomized method from Bhavnagar district from Swami Vivekananda homoeopathic medical college and hospital as well as my private OPD at Vrushti Homoeopathic clinic,Jail Road, Bhavnagar. Result:In this study age group of 0-3 and 3-6 are found more liable to get summer diarrhoea .As far as sex distribution is concern male: female is almost same. Cold food, cold drink, ice gola, out-side food, drinking impure water and swimming are found as major causative factors. As far as miasms are concern more cases (almost 60%) are found to have psora in background.Zingiber was used in various potencies in diarrhoea cases and assessment was done on the basis of improvement in terms of reducing intensity, duration and frequency of cases of acute summer diarrhoea. Purposive Sampling for research purpose has been done. Selection of the medicine is according to totality of symptoms. Selection of the potency and repetition was based on laws of Homeopathic Posology which is described in Organon of medicine. Cases were followed for 6 months. Conclusion:There is a better scope in Homoeopathic for the treatment of summer diarrhoea, since the treatment is based on holistic and individualistic approach. A homoeopathic remedy Zingiber not only annihilates the disease but also prevents the complications associated with it.
ABSTRACT
Background: Acute respiratory tract infections (ARTIs) are a major burden to child health in developing countries like India. Preschool children have 4–8 episodes of the upper respiratory tract infection (URTI) per year on average, while school-aged children experience 2–6 episodes per year. They are the most prevalent reason for visits to the outpatient section of a hospital and general practice. Aim and Objective: The aim of this study was to evaluate the prescribing patterns in patients aged 1–18 years with URTIs. Materials and Methods: A prospective study conducted in the department of pharmacology at a tertiary health care center. Two hundred and fifty patients with URTI visiting pediatric and ENT department of tertiary health care center during December 2014–June 2015 were studied. Data included detailed history, physical examination, investigations, antimicrobial treatment given, and other treatment given were noted. This data was gathered from the records of Pediatric and ENT department. Statistical tests were used to analyze the data. Results: The most common clinical presentation was fever and cough. The common diagnosis noted in the study were non-specific URTI, tonsillitis, and sinusitis. Antipyretics (99.6%) and antibiotics (52%) were the frequently prescribed drugs among the patients. Amoxicillin-clavulanic acid and cephalosporins were the common antibitoics prescribed. Beta-hemolytic streptococci were the common microbe isolated among the patients tested to know the etiology. Conclusion: Antipyretics (99.6%) and antibiotics (52%) were the frequently prescribed drugs among the patients. Antibiotics were prescribed in most of the non-specific URTI and pharyngitis which is a matter of concern.
ABSTRACT
Upper respiratory tract is directly connected with the external environment， and its natural immune system is the first line of defense against pathogens. In antiviral infection， interferon （IFN） is the main component of the antiviral natural immune system and IFN-λ is a newly discovered immune effector molecule that is mainly produced in the mucosal barrier. IFN-λ exerts a biological role through Janus kinase （JAK） and signal transducer and activator of transcription （STAT） signaling pathway， and plays an important part in regulating innate and acquired immunity of respiratory mucosa. IFN-λ principally expresses on the mucosal barrier with a long-lasting antiviral impact and controls immune-inflammatory damage， which is becoming a new focus of antiviral immunity research in the upper respiratory tract， especially in fighting against 2019 novel coronavirus diseases （COVID-19）. Thus， we summarize the research progress of IFN-λ antiviral immunity in the upper respiratory tract to provide new insight in the prevention and treatment of viral infection in the upper respiratory tract.
ABSTRACT
Objective To investigate the viral infection subtypes and epidemiological characteristics of upper respiratory tract infection (URTI) in Beijing area in 2020, and to provide references for URTI specific treatment and vaccination. Methods A total of 22 318 patients with URTI in Beijing area from January 2020 to December 2020 were enrolled in the study. Basic demographic information and clinical characteristics of the patients were collected, and their respiratory tract samples were collected. Eight major respiratory viruses (including respiratory syncytial virus, parainfluenza virus, adenovirus, coronavirus, influenza virus, rhinovirus, bocavirus, and metapneumovirus) in the respiratory samples were detected by PCR. The pathogen composition and epidemiological characteristics of URTI were analyzed. Results ① Among the 22 318 cases of URTI, most of them were children under 5 years old and elderly patients over 70 years old, accounting for 25.02% and 19.43%, respectively; ② URTI mainly occurred in spring (35.71%) and winter (37.35%); ③ The total positive rate of respiratory virus was 49.35%, among which 45.42% were infected with single virus, 3.30% were infected with two viruses, and 0.63% were infected with three or more viruses; ④ Respiratory syncytial virus (49.35%) had the highest detection rate, followed by parainfluenza virus (12.98%), rhinovirus (9.48%), influenza virus (8.40%), adenovirus (6.01%), bocavirus (4.43%), coronavirus (3.97%), and metapneumovirus (2.90%); ⑤ The detection rates of respiratory syncytial virus and parainfluenza virus in children aged 0-5 years old and the elderly aged over 71 years old were higher than those in other age groups, while the detection rates of other pathogens of all age groups were similar; ⑥ Among 22,318 URTI patients, 290 cases were complicated with pneumonia, with a complication rate of 1.300%. The complication rate of pneumonia in patients with positive virus pathogens was significantly higher than that in patients with negative virus pathogens (χ2=18.011, P2=884.085, P<0.05). Conclusion Children under 5 years old and the elderly over 70 years old are the high-risk population of URTI, and URTI mainly occurs in spring and winter. Respiratory syncytial virus and parainfluenza virus are the main pathogens leading to URTI, and patients with virus infection and mixed virus infection suffer a higher risk of pneumonia.
ABSTRACT
Objective To explore the correlation between acute upper respiratory tract infection and meteorological factors in Zigong area from 2016 to 2021. Methods All acute upper respiratory tract infection cases from the Emergency Department of the First People's Hospital of Zigong City from 2016 to 2021 and meteorological data (including but not limited to temperature, relative humidity, air pressure, sunshine time, wind speed, etc.) during the same period were collected. Cases were screened from emergency electronic data, and medical records that met the criteria were included in this study to analyze the relationship between acute upper respiratory tract infection and meteorological factors. Results A total of 5 608 patients were enrolled in this study, including 3,893 males (69.42%) and 1,715 females (30.58%), with an average age of 50.17±9.81 years. The predisposing factors were climate change in 2331 cases (41.57%), history of chronic respiratory diseases in 1458 cases (26.00%), low immune function in the elderly or young children in 1106 cases (19.72%), vitamin deficiency in 512 cases (9.13%), and others in 201 cases (3.58%). Acute upper respiratory infections in Zigong area occurred all year round. Spring had more respiratory infections than other seasons, and the season with the fewest infections was autumn. Among them, May had the highest number of cases (650 cases), followed by January (592 cases). September had the least number of cases (475 cases), followed by August (480 cases). The daily incidence of upper respiratory tract infection in this area was negatively correlated with daily average temperature, sunshine duration and daily precipitation (rdaily average temperature=-0.635, Pdaily average temperature=0.027; rsunshine duration=-0.678, Psunshine duration=0.015; rday precipitation=-0.691, pday precipitation=0.013), and positively correlated with the daily temperature range and 24 hrs pressure change (rtemperature daily range=0.644, Ptemperature daily range=0.024; r24hrs change pressure=0.579, P24hrs change pressure=0.049). AURI-induced complications were negatively correlated with daily average temperature (rdaily average temperature=-0.718, P daily average temperature=0.009), and positively correlated with daily temperature range (rtemperature daily range=0.651, Ptemperature daily range=0.022). The analysis of multi-factor regression integration showed that the consistency of the test results exceeded 70%, and it exceeded 85% at the same level or adjacent levels. Conclusion From 2016 to 2021, acute upper respiratory tract infection occurs throughout the year in Zigong, with the most in spring and the least in autumn. May and September are the two months with the highest and lowest number of cases, respectively. The number of cases is affected by the average daily temperature, sunshine duration, daily precipitation, daily temperature range and 24hrs variable pressure. The establishment of a respiratory medical weather forecast model by season has a strong forecasting ability for the number of acute upper respiratory infections.

ABSTRACT
OBJECTIVE@#To assess the effectiveness of Jiuwei Zhuhuang Powder (JWZH), a Tibetan patent medicine in treating upper respiratory tract infection (URTI) associated cough in children.@*METHODS@#The study was a multicenter, randomized, open-label, controlled trial. A total of 142 children aged 2 to 14 years old, with URTI-associated cough within 48 h of onset, were randomly assigned to two groups at a 1:1 ratio by computer-generated randomization sequence. Children were treated with JWZH (1 to 1.5 g, twice to thrice daily) in the treatment group or conventional treatment (Pediatric Paracetamol, Artificial Cow-bezoar and Chlorphenamine Maleate Granules, 0.25 to 1 g, thrice daily) in the control group for 5 days. The primary endpoints were the time to cough resolution and 4-day cough resolution rate. The secondary endpoints were the daily improvement in symptom scores and cough resolution rate during the study period.@*RESULTS@#A total of 138 children were included in the intention-to-treat analysis, with 71 cases in the treatment group and 67 cases in the control group. Compared with the conventional treatment, the children receiving JWZH had a shorter time to cough resolution [hazard ratio, 2.10; 95% confidence interval (CI), 1.29-3.40; P=0.003]. The median time to cough resolution for children receiving JWZH was shorter than that of the conventional treatment (2 days vs. 3 days; P<0.001). The 4-day cough resolution rate in the JWZH group was higher than that of the control group (94.4% vs. 74.6%; risk difference: 19.8%, 95% CI: 8.1%-31.5%; relative risk: 1.265, 95% CI: 1.088-1.470; P=0.001). There were no statistically significant differences in the improvement of other symptoms caused by URTI (P>0.05). Adverse events was reported in 5.6% (4/71) and 4.5% (3/67) in participants of JWZH and PPACCM groups (P>0.05), respectively, which were all mild and resolved without treatment.@*CONCLUSION@#JWZH seemed to be a safe and effective therapy for URTI-associated cough in children.

ABSTRACT
Feline calicivirus is among the most common pathogenic microorganisms in upper respiratory tract disease (URTD) and oral lesions of cats. It leads to stomatitis, oral ulceration, ocular and nasal discharge, conjunctivitis, fever, lameness, anorexia, hypersalivation, pneumonia, respiratory distress, coughing, and depression in infected cats. This study aimed to determine the role of Feline calicivirus (FCV) in cats with the upper respiratory tract disease in the Diyarbakir region, Turkey, to provide treatment for infected cats and contribute to the disease prophylaxis. The study material consisted of 10 cats (control group) considered to be healthy according to the clinical examination and 20 cats with URTD that were not vaccinated against Feline calicivirus infection of different breeds, ages, and genders brought to Dicle University Veterinary Faculty Prof. Dr. Servet SEKIN Polyclinic with URTD. After routine clinical examinations of the animals, oral and conjunctival swabs and blood samples were taken. Hematological and biochemical analyzes of blood samples were performed. Swab samples were analyzed by the polymerase chain reaction (PCR) method for the diagnosis of the agent. Oral lesions, hypersalivation, ocular and nasal discharge, coughing, and breathing difficulties were seen in clinical examinations of cats with URTD. Feline calicivirus was detected in only one cat's conjunctival swab sample in PCR analyses. As a result, we found that Feline calicivirus infection was present in cats with URTD in the Diyarbakir region, and 5% positivity was found in cats with clinical symptoms according to PCR analysis.(AU)
O calicivírus felino está entre os microrganismos patogênicos mais comuns nas doenças do trato respiratório superior de gatos, determinando estomatites, ulcerações orais, descarga ocular e nasal, conjuntivite, febre, manqueira, anorexia, hipersalivação, pneumonia, distúrbios respiratórios, tosse e depressão. O presente trabalho foi delineado para determinar o papel do calicivírus felino (CVF) em gatos com doenças do trato respiratório superior na região de Diyarbakir, Turquia. Com o objetivo de orientar a prescrição do tratamento para os gatos infectados e contribuir com a profilaxia da doença. O material de estudo consistiu em 10 gatos saudáveis sem qualquer problema de saúde e 20 gatos acometidos por doenças do trato respiratório superior que não haviam sido vacinados contra a infecção pelo calicivírus felino. Os animais de diferentes raças, idades e gêneros foram encaminhados para a Universidade de Dicle, na Faculdade de Veterinária, na policlínica Professor Dr. Servet Sekin.

BACKGROUND@#An acute upper respiratory tract infection (URI) is the most common disease worldwide, irrespective of age or sex. This study aimed to evaluate the short-term effect of diurnal temperature range (DTR) on emergency room (ER) visits for URI in Seoul, Korea, between 2009 and 2013.@*METHODS@#Daily ER visits for URI were selected from the National Emergency Department Information System, which is a nationwide daily reporting system for ER visits in Korea. URI cases were defined according to International Classification of Diseases, 10@*RESULTS@#There were 529,527 ER visits for URI during the study period, with a daily mean of 290 visits (range, 74-1942 visits). The mean daily DTR was 8.05 °C (range, 1.1-17.6 °C). The cumulative day (lag 02) effect of DTR above 6.57 °C per 1 °C increment was associated with a 1.42% (95% confidence interval [CI] 0.04-2.82) increase in total URI. Children (≤ 5 years of age) were affected by DTR above 6.57 °C per 1 °C, with 1.45% (95% CI 0.32-2.60) at lag 02, adults (19-64 years) with 2.77% (95% CI 0.39-5.20) at lag 07. When the DTR (lag02) was 6.57 °C to 11.03 °C, the relative risk was significant at 6.01% (95% CI 2.45-9.69) for every 1 °C increase in youth subjects aged for 6 to 18 years.@*CONCLUSIONS@#DTR was associated with a higher risk for ER visits for URI. In addition, the results suggested that the lag effects and relative risks of DTR on URI were quite different according to age.

Objective:To explore the clinical diagnosis and treatment characteristics as well as the optimal schemes of Lianhua Qingwen Capsule in the treatment of upper respiratory tract infection （URTI） in the real world. Method:The information of 454 patients receiving Lianhua Qingwen Capsule for URTI was collected from the electronic medical data warehouse constructed by the Institute of Basic Research in Clinical Medicine， China Academy of Chinese Medical Sciences， which covered 16 large-scale tertiary Class A hospital information systems （HISs）. The harvested information was subjected to descriptive analysis， Apriori algorithm-based analysis and Louvain （BGLL） algorithm-based complex network analysis to explore the clinical medication schemes. Result:The commonly adopted medication schemes were heat-clearing and detoxicating Chinese medicinal injections combined with expectorants， analgesic-antipyretic drugs， or antibacterial agents in western medicine. Besides， the combination with heat-clearing and phlegm-resolving Chinese medicinals， vitamins， or hypotensive， lipid-lowering， hypoglycemic， coronary circulation-improving， or antiplatelet aggregation drugs targeting the underlying diseases was also detectable. Conclusion:The complex network analysis based on BGLL clustering method can be used to find out the medication rules of Lianhua Qingwen Capsule for URTI. The traditional Chinese medicine has been widely employed for resolving phlegm and relieving cough due to its good efficacy. The combination with antibiotics follows the guidelines for the use of antimicrobial agents. Drug safety is one of the most concerned aspects in clinical drug combination. The uncovering of these rules has provided a direction for exploring the optimal treatments.
ABSTRACT
Objective To investigate the virus epidemiological characteristics in patients with acute upper respiratory tract infection, so as to provide a basis for clinical treatment. Methods A total fo 1 306 inpatients or outpatients with acute upper respiratory tract infection in our hospital from January 2017 to January 2020 were enrolled. The respiratory viruses in nasopharyngeal swab samples were detected by fluorescence immunoassay. The detection rate, clinical characteristics, seasonal distribution, and age distribution of each virus were analyzed. Results In 1 306 patients with acute upper respiratory tract infection, 679 cases were positive for virus culture, with a total positive detection rate of 51.99%. Among the single virus infections, 463 cases were positive for FluV, with a positive detection rate of 35.45%. Five different virus infections showed significant difference among 0 ~ years old, 14 ~ years old, 50 ~ years old and 65 ~ years old groups (P<0.05). The positive detection rates of FluV, PIV, RSV, and RV were the highest in the 0 ~ years old group, while ADV detection rate was the highest in the 65 ~years old group. The distribution of the 5 different viruses in spring, autumn and winter was significantly different (P<0.05). Conclusion Acute upper respiratory tract infection is mainly caused by a single virus, and different viruses has significant differences in age and seasonal distribution.
ABSTRACT
@#Introduction: Since pharyngitis in adults is one of the most common infectious diseases seen in general practitioner consultations in Malaysia, data on pharyngitis among adults concerning to its prevalence, socio-demographic, risk factors and clinical manifestations is very much lacking. This study aims to determine the prevalence of pharyngitis among adults in Sepang, Selangor, Malaysia from 2016 to 2017 and its associated demographic and risk factors. Methods: We conducted a cross-sectional study on 215 adult patients with a sore throat as the main symptom and who did not receive any antibiotic treatment within two weeks at three Malaysian primary care clinics. The researchers assessed the participants’ clinical manifestations and collected throat swabs for culture to determine the presence of group A streptococcus (GAS). Data on demographic characteristics, clinical manifestation and throat swab culture results were analyzed using chi-square test and multivariate logistic regression. Results: Pharyngitis was diagnosed in 130/215 (65%) adults with a sore throat. Only six isolates (2.8%) were identified as GAS. The overall mean age ± S.D was 36.43 ± 15.7. The majority of the participants were in the age group of 18-28 years. There were 42.3% males and 57.7% females; most participants were Malay 62.8%, followed by 30.2% Indian, 5.1% Chinese, and 1.9% other ethnicities. The most common symptom among the participants was cough 196 (91.2%), followed by rhinorrhea 161 (74.8%), tonsillar swelling or exudates 68 (31.6%), inflamed or reddish of pharynx 62 (28.8%), swollen anterior cervical lymph nodes 50 (23.3%), and fever ≥37.5°C 28 (13.0%). Conclusion: Besides, there was no significant association between pharyngitis and the demographic variables; the current findings emphasized that inflamed or reddish pharynx, tonsillar swelling or exudates were among the factors associated with pharyngitis.
ABSTRACT
Objective To understand the status of acute upper respiratory tract viral and bacterial infections in children in Chengdu and to analyze its epidemiological characteristics. Methods From April 2018 to April 2020, 1,324 children with acute upper respiratory tract infection admitted to Chengdu Second People's Hospital were enrolled in the study. Pathogens from throat swab specimens were cultured, isolated, and identified. Results Among 1 324 specimens, the detection rate of bacterial and viral infection was 76.44% (1 012/1 324). The detection rate of simple viral infection was 50.40%, the detection rate of simple bacterial infection was 16.21%, and the detection rate of mixed infection was 33.40%. Haemophilus influenzae was the main bacterial type and respiratory syncytial virus A was the main virus type. The positive rate of upper respiratory tract viral infection among children with different ages was significantly different (P<0.05). The positive rate of viral and bacterial upper respiratory tract infection showed a statistically significant difference among different infection seasons (P<0.05). In addition, the positive rate of viral upper respiratory tract infection among children from different districts had statistically significant difference (P<0.05). Conclusion Children with upper respiratory tract infections in Chengdu area are mainly viral infections. Haemophilus influenzae and respiratory syncytial virus A are the main pathogens of upper respiratory tract infections in children. 0~1 year old is the age with the highest incidence of upper respiratory tract bacterial infection, while 1~4 years old is the age with the highest incidence of virus infection. Children in urban areas and in winter have higher positive rates of upper respiratory tract infections.
ABSTRACT
This study aimed to quantify nasosinusal neoplasms diagnosed in dogs in 20 years (2000-2019) and characterize the main clinical, macroscopic, and histological aspects of these neoplasms. The sex, breed, age, skull conformation, the main clinical signs, and the anatomopathological characteristics (distribution, macroscopy, and histology) were computed. During this period, 49 dogs were affected by neoplasms in these regions, totaling 50 neoplasms (one dog had two neoplasms of different locations and histogenetic origins). Similar amounts of mixed-breed dogs (25/49) and purebred dogs (24/49) were affected, these distributed in 16 breeds. Among purebreds, it was noted that dogs with mesocephalic cranial conformation (12/24) were the most affected, followed by dolichocephalic (10/24) and brachycephalic (2/24). There were 22 cases in males and 27 in females, making a proportion of 1:1.23. There was an age variation from 11 months to 16 years old. The epithelial neoplasms have occurred in older dogs compared to those of other histogenic origins (mesenchymal and other origins/round cells). The main clinical signs were similar between the histogenetic categories, related to the involvement of the upper respiratory tract, sometimes accompanied by nervous signs (when there was brain invasion of nasal neoplasms or vice versa). The possible origin site was mostly in the nasal cavity concerning the paranasal sinuses (and other locations). Invasions occurred in different tissues adjacent to the nasal cavity and paranasal sinuses, resulting in cranial and facial deformities (21/49). The frequency was 48% of epithelial neoplasms, 32% of mesenchymal neoplasms, and 10% of neoplasms with other origins and round cells. The neoplasms most frequently observed, in decreasing order of frequency, were: adenocarcinoma (9/50), squamous cell carcinoma (9/50), transmissible venereal tumor (5/50), osteosarcoma (5/50), chondrosarcoma (4/50), and undifferentiated sarcoma (4/50). Through this study, it was possible to establish the frequency of these neoplasms in 20 years and their clinical, macroscopic, and histological characteristics.(AU)
Este estudo teve como objetivo quantificar os neoplasmas nasossinusais diagnosticados em cães em 20 anos (2000-2019) e caracterizar os principais aspectos clínicos, macroscópicos e histológicos desses neoplasmas. Foram computados sexo, raça, idade, conformação do crânio, principais sinais clínicos e características anatomopatológicas (distribuição, macroscopia e histologia). Nesse período, 49 cães foram acometidos por neoplasmas nessas regiões, totalizando 50 neoplasmas (um cão tinha dois neoplasmas de localização e origens histogenéticas distintas). Foram acometidas quantidades semelhantes de cães sem raça definida (25/49) e de cães com raça definida (24/49), estes distribuídos em 16 raças. Entre os cães com raça definida, notou-se que os cães com conformação craniana mesocefálica (12/24) foram os mais acometidos, seguidos pelos dolicocefálicos (10/24) e braquicefálicos (2/24). Foram observados 22 casos em machos e 27 em fêmeas, perfazendo a relação de 1:1,23. Ocorreu uma variação de idade de 11 meses a 16 anos; tendo os neoplasmas epiteliais ocorrido em cães mais velhos quando comparado aos de outras origens histogênicas (mesenquimais e outras origens/células redondas). Os principais sinais clínicos foram semelhantes entre as categorias histogenéticas, sendo relacionados ao comprometimento do trato respiratório superior, por vezes acompanhados de sinais nervosos (quando houve invasão encefálica de neoplasmas nasais ou vice-versa). O possível local de origem em sua maioria foi na cavidade nasal em relação aos seios nasais (e de outras localizações). Ocorreram invasões para diferentes tecidos adjacentes à cavidade nasal e seios paranasais, tendo como consequência deformidades cranianas e faciais (21/49). A frequência foi de 48% de neoplasmas epiteliais, 32% de neoplasmas mesenquimais e 10% de neoplasmas com outras origens e de células redondas. Os neoplasmas mais frequentemente observados, em ordem decrescente de frequência, foram: adenocarcinoma (9/50), carcinoma de células escamosas (9/50), tumor venéreo transmissível (5/50), osteossarcoma (5/50), condrossarcoma (4/50) e sarcoma indiferenciado (4/50). Com isso, pode-se estabelecer a frequência desses neoplasmas em 20 anos, bem como suas características clínicas, macroscópicas e histológicas.(AU)
