Real-world evidence (RWE) is clinical evidence on a medical product’s safety and efficacy that is generated using real-world data (RWD) resulting from routine healthcare delivery. This study evaluates the clinical efficacy of amoxicillin + clavulanic acid in children with pharyngitis, acute otitis, or acute rhinosinusitis with suspected bacterial origin under normal office and home conditions. Methods: This was a real-life, prospective, observational, pharmacovigilance study. It included children of both sexes between 2 and 12 years old, with a diagnosis of Rhinopharyngitis (tonsillitis), Acute Otitis Media and Rhinosinusitis. The main effectiveness variable evaluated was reduction and time to resolution of symptoms. All patients received Amoxicillin/Clavulanic Acid suspension 600 mg/42.9 mg/5 mL at a dose of 90 mg/Kg/day in two doses, every 12 hours for 7 days. The evaluations were carried out at the beginning, at 72 hours (3rd day) and at 7 days. All patients underwent culture and antibiogram. Results: The majority of cultures were negative for pathogenic germs, suspecting unidentifiable germs, or viral etiology despite the rigorous selection of subjects following validated scores. The most frequently isolated germ was Staphylococcus aureus;growth of gram-negative bacteria was reported in 33.33% of the cultures. There was a significant improvement in symptoms in children with tonsillitis and rhinosinusitis from the first 72 hours of treatment, persisting until the 7 days. In the otitis media group, returning to normal by the tenth day. During the conduction of this investigation, no adverse effects associated with the prescribed therapy were reported. 展开更多

We here present the case of a 22-year-old female of Suriname ethnicity with ulcerative colitis who received treatment with mercaptopurine and infliximab.She presented herself with a severe necrotizing tonsillitis due to herpes simplex virus type-1(HSV-1).Combination therapy consisting of immunomodulators and anti-tumor necrosis factor(TNF) agents is increasingly being used.Anti-TNF therapy is associated with an increased risk of developing serious infections,and especially patients receiving combination treatment with thiopurines are at an increased risk.We here show that HSV infections can cause a severe tonsillitis in immunocompromised patients.Early recognition is essential when there is no improvement with initial antibiotic therapy within the first 24 to 72 h.HSV infections should be in the differential diagnosis of immunocompromised patients presenting with a necrotizing tonsillitis and can be confirmed by polymerase chain reaction.Early treatment with antiviral agents should be considered especially if antibiotic treatment fails in such patients. 展开更多

To systematically evaluate the efficacy and safety of Pudilan Xiaoyan Oral in Liquid(蒲地蓝消炎口服液)in the treatment of suppurative tonsillitis in children.In WanFang,CNKI,VIP,CBM,PubMed,Embase and Corchrane and other databases,relevant literatures about Pudilan Xiaoyan Oral Liquid(蒲地蓝消炎口服液)in the treatment of pediatric suppurative tonsillitis were searched.The retrieval time was from the establishment of the database to April 2019.Relevant randomized controlled trials were extracted.The control group was treated with conventional antibiotics,and the observation group was treated with Pudilan Xiaoyan Oral Liquid(蒲地蓝消炎口服液)based on the control group.After they were summarized and analyzed,Cochrane Handbook 5.1 evaluation standard and RevMan 5.3 software were used to determine the quality of literature.A total of 172 literatures were retrieved and 23 randomized controlled trials were included.A total of 1188 children were in the experimental group while 1175 children were in the control group,involving 2363 children with suppurative tonsillitis.Meta-analysis showed that the total effective rate of Pudilan Xiaoyan Oral Liquid(蒲地蓝消炎口服液)combined with routine treatment was better than that of routine treatment(RR=0.88,95%CI(0.86,0.91),P<0.00001);Pudilan Xiaoyan Oral Liquid(蒲地蓝消炎口服液)combined with routine treatment in children was better than that of routine treatment alone in term of temperature recovery,sore throat time,the reduction of tonsil purulent secretion.There were few reports of adverse reactions and no serious adverse reactions.To sum up,Pudilan Xiaoyan Oral Liquid(蒲地蓝消炎口服液)combined with routine treatment can significantly improve the efficacy of children with suppurative tonsillitis,but due to the low quality of the included literature,it should be used cautiously.It is suggested that clinical randomized controlled trials should be designed with large sample size,multi-centers and conforming to international standards to improve the quality of evidence. 展开更多

The germs in question are mostly viruses and bacteria. Objectives: The objective of this work was to study the epidemiological and therapeutic profile of tonsillitis and their complications in the ENT Department and Head and Neck Surgery of the Mother-Child University Hospital in Luxembourg. Patients and Methods: This is a prospective study over a 12-month period from January 2018 to December 2018, including all patients who presented with tonsillitis and/or their complications. Results: Three hundred and fifteen (315) patients were collected during this period. The average age in our study was 14.25 years with extremes ranging from 2 years to 61 years. The sex ratio was 0.65 in favor of the female sex. During this period we recorded 80.95% of cases of uncomplicated tonsillitis including 60.50% for acute tonsillitis, 24.5% for chronic tonsillitis 5% for adenoid tonsillitis and 19.05% for complications. Complications included peritonsillar phlegmon 42.22%, heart disease 33.33%, cervical cellulitis 8.89%, adeno-phlegmon 6.67%, para-pharyngeal abscess 4.44%, and sepsis 4.44%. The exclusive medical treatment was performed in 44.31%. Surgical treatment (drainage incision and tonsillectomy) was performed in 55.69%. Conclusion: Tonsillitis and its complications represent an important pathology in ENT. Feynophagy febrile is the pair-origin symptom that can lead to the diagnosis. The prevention of complications is the guarantor of the reduction of its morbidity. We recommend that in the absence of RDT (Rapid Diagnostic Test), it is necessary to systematize antibiotic therapy to prevent serious complications. 展开更多

Tonsillectomy is the most common procedure for treatment of pediatric recurrent acute tonsillitis and tonsillar enlargement that contributes to obstructive sleep apnea hypopnea syndrome.Postoperative hemorrhage of tonsillectomy is a lifethreatening complication.AIM To identify the risk factors that may contribute to primary and secondary postoperative hemorrhage in pediatric tonsillectomy.METHODS The clinical data from 5015 children,3443 males and 1572 females,aged 1.92-17.08 years,with recurrent tonsillitis and/or tonsil hypertrophy who underwent tonsillectomy in our hospital from January 2009 to December 2018 were retrospectively collected.The variables including sex,age,time of onset,diagnosis,method of tonsillectomy,experience of surgeon,time when the surgery started and monthly average air temperature were abstracted.The patients with postoperative hemorrhage were classied into two groups,the primary bleeding group and the secondary bleeding group,and their characteristics were compared with those of the nonbleeding group separately.Statistical analysis was performed by chi-square test with SPSS 20.RESULTS Ninety-two patients had post-tonsillectomy hemorrhage,and the incidence rate of post-tonsillectomy hemorrhage was 1.83%.The mean age was 5.75 years.Cases of primary hemorrhage accounted for approximately 33.70%(31/92),and cases of secondary hemorrhage occurred in 66.30%(61/92).The rate of reoperation for bleeding was 0.92%,and the rate of rehospitalization for bleeding was 0.88%in all patients.Multiple hemostasis surgery was performed in 6.52%(3/46)of patients.The method of tonsillectomy(coblation tonsillectomy)and experience of the surgeon(junior surgeon with less than 5 years of experience)were significantly associated with primary hemorrhage(χ^(2)=5.830,P=0.016,χ^(2)=6.621,P=0.010,respectively).Age(over 6 years old)and time of onset(more than a 1-year history)were significantly associated with secondary hemorrhage(χ^(2)=15.242,P=0.000,χ^(2)=4.293,P=0.038,respectively).There was no signicant difference in sex,diagnosis,time when the surgery started or monthly average air temperature.There was a signicant difference in the intervention measures between the primary bleeding group and the secondary bleeding group(χ^(2)=10.947,P=0.001).The lower pole and middle portion were the common bleeding sites,followed by the upper pole and palatoglossal arch.CONCLUSION The incidence rate of post-tonsillectomy hemorrhage is low.Coblation tonsillectomy and less than 5 years’experience of surgeon contribute to the tendency for primary hemorrhage.Age and time of onset are responsible for secondary hemorrhage. 展开更多

The prognosis of metastatic palatine tonsil cancer is poor. A 53-year-old man presented with painless left palatine tonsillar swelling and a cervical mass following right hemicolectomy for an ascending colon adenocarcinoma. Physical examination showed an ulcerated mass located on the upper pole of the left palatine tonsil. A punch biopsy was taken for histological examination which showed a moderately- differentiated adenocarcinoma. The patient was treated with palliative radiotherapy and chemotherapy. He was still alive when we wrote this paper. Our case shows that immunohistochemical diagnosis of metastatic palatine tonsil cancer is essential. 展开更多

BACKGROUND Lymphomas are the second most common malignancy of the head and neck.In this region,the vast majority of extranodal lymphomas are located in the palatine tonsil,accounting for about 51%.Tonsillar lymphomas are aggressive tumors with intermediate-or high-grade histology.We here report a case of primary non-Hodgkin’s lymphoma of the palatine tonsil and analyze its ultrasound features.CASE SUMMARY A 40-year-old man presented with right palatine tonsil swelling for 2 mo after a cold,accompanied by dysphagia,snoring,and suffocation.He had no sore throat,fever,or history of upper respiratory tract infection or tuberculosis.The patient was generally in good health and denied other diseases.He was diagnosed with acute tonsillitis initially and treated with antibiotics for 7 d.However,there was no improvement with the treatment.Tonsil biopsy and ultrasound-guided biopsy of the biggest lymph node of the right neck showed the typical pathology of non-Hodgkin lymphoma.CONCLUSION Primary lymphoma of the tonsils is rare,and its diagnosis is challenging.Ul-trasound is a useful modality in diagnosing oropharyngeal diseases,and can clearly show the features of this tumor,but the final diagnosis should be estab-lished by histology. 展开更多
