Infantile Intraparenchymal Brain Abscess due to Streptococcus pyogenes

Introduction Group A ß-hemolytic streptococcus (GABHS) are the most common bacterial cause of tonsillitis, and can cause noninvasive diseases such as pharyngitis and impetigo, as well as more severe invasive diseases. The incidence of invasive disease is 1-3/100,000 per year, and the morbidity and mortality rate is high. GABHS is rarely lead to brain abscesses. Case Report Acute phase reactants were found to be high in a 40-day-old patient who presented with fever, irritability and focal seizures. Acute phase reactants were high. Transfontanel ultrasonography showed increased thickness, echo and blood supply in the meninges. Brain magnetic resonance imaging (MRI) and diffusion MRI revealed a thick-walled abscess in the right cerebral hemisphere and parietooccipital parenchyma with diffusion restriction on diffusion-weighted images. Cerebrospinal fluid (CSF) polymerase chain reaction (PCR) test revealed S. pyogenes,and S. pyogenes grown in CSF culture. Initially, meropenem, vancomycin, metronidazole antibiotherapy was applied. Treatment was revised to cefotaxime and vancomycin after culture antibiogram and was completed for 8 weeks. Seizures regressed. Control brain imaging showed improvement. Restriction in left lower extremity movements remained. Physical therapy and rehabilitation was recommended and he was discharged. Conclusion GABHS, which is the causative agent of acute tonsillitis, rarely causes invasive disease which has high mortality and morbidity.

Seasonal variation and demographic characteristics of acute tonsillitis and peritonsillar abscess in ENT practices in Germany (2019-2023).

Peritonsillar abscess (PTA) is a common soft tissue infection of the head and neck. It remains unclear to what extent inflammatory diseases of the palatine tonsils or other infections contribute to the development of PTA. This study examines the demographic characteristics and seasonal variations of acute tonsillitis (aT) and PTA in ENT practices in Germany using a practice database. Retrospective analysis based on data from the German-wide IQVIA™ Disease Analyzer database for the period 2019 to 2023. Data include diagnoses of aT (ICD-10: J03) and PTA (ICD-10: J36) as well as patient demographics (age, sex). Seasonal variations were identified by analysing the monthly diagnosis rates. The Pearson correlation between the monthly case numbers of aT and PTA was determined. 59,934 cases of aT and 5,024 cases of PTA were recorded. The mean age was 30.3 years (aT) and 39.4 years (PTA). The proportion of female patients was 60% (aT) and 49% (PTA). Both diagnoses showed seasonal variations with peaks in winter and spring and a decline in summer, although the decline was less pronounced for PTA. The monthly case numbers of aT and PTA showed high correlations between r = 0.75 (2019) and r = 0.94 (2020). The average correlation for the period 2019-2023 was r = 0.81. During the coronavirus pandemic, a significant decrease in the case numbers of both diseases was observed, while the typical seasonal variations disappeared. After the pandemic, the case numbers increased to higher levels than before the pandemic. aT and PTA both show seasonal variations with peaks in winter and spring and a decline in summer. The correlation between the variations of aT and PTA could be related to a partly common aetiology or to the specific sample of the practice database. The attenuation of seasonal variation during the coronavirus pandemic illustrates the impact of COVID-19 on the incidence of other diseases and on the use of healthcare pathways by patients.

An integrated approach to the treatment of a patient with chronic tonsillitis. Clinical case

Chronic tonsillitis (CT) is a common infectious-allergic disease leading to severe general somatic complications, including rheumatic damage of joints and heart, kidney disease. Currently in Russia there is an increase in the number of patients with CT. Therapy for CT in outpatient practice is often limited to only washing the lacunae of the palatine tonsils, without the use of local drugs. We observed a 35-year-old patient with a diagnosis of chronic tonsillitis and a history of the disease of more than 1.5 years. A combined method of therapy was chosen, including treatment with the Tonsillor apparatus using low-frequency ultrasound therapy and local use of Viroxinol for irrigation of the tonsils and mucous membrane. As a result of the complex treatment, pronounced positive dynamics and a decrease in the clinical symptoms of CT were achieved.

ENT manifestations and surgical interventions in patients with HIV

Background. Human Immunodeficiency Virus (HIV) infection represents a significant global health challenge, being one of the most interesting areas of current medicine regarding immunosuppression. Objective. The purpose of this study is to clinically evaluate the ear, nose, and throat (ENT) manifestations in HIV-positive patients and to determine the outcomes after surgical treatment of these manifestations. Methods. The clinical study sample included 223 HIV-positive patients from several hospitals in Romania, collected between 2018 and 2022, who presented with ENT complications and were treated for the remission of these manifestations. Results. The most common ENT complications diagnosed in HIV patients include persistent oral candidiasis, laterocervical adenopathies, acute tonsillitis, acute and chronic rhinosinusitis, otomycosis, and acute suppurative otitis media. Conclusion. HIV-positive patients require regular follow-up by an otorhinolaryngologist. Surgical interventions for immunosuppressed patients necessitate a multidisciplinary approach.

Analysis on Syndrome and Treatment of Shaoyin Cold Type Acute Tonsillitis

Acute tonsillitis belongs to the category of "milk moth" in traditional Chinese medicine. TCM clinical syndrome differentiation is often divided into two types: wind-heat pathogens affecting the lung meridian and dietary excess leading to heat accumulation in the lungs and stomach. The author's clinical practice found that some acute tonsillitis patients are often manifested as Shaoyin cold type, and the syndrome and treatment of general acute tonsillitis are totally different. "Throat Science Family Instructions" put forward the specific treatment of pharyngeal pain is Shaoyin typhoid type, and the prescription is Banxia Gangui Decoction, which is composed of eight kinds of drugs: Guizhi, Banxia, Fuling, Jiegeng, Yiyiren, Buguzhi, Ganjiang, and Zexie. It is traditionally used to treat symptoms such as sore throat, diarrhea, deep and thin pulse, and white tongue coating without thirst. Combining theory and clinical experience, the author reports successful clinical outcomes using this decoction to treat acute tonsillitis of the Shaoyin cold type. This paper aims to analyze the internal connection between Banxia Gangui Decoction and Shaoyin cold type acute tonsillitis. The paper outlines the symptom characteristics, etiology and pathogenesis, treatment based on syndrome differentiation, differential diagnosis of this condition, along with the therapeutic rationale for Banxia Gangui Decoction. A case study is included.

The Effect of Children with Acute Tonsillitis on the Rate of Sedimentation of Red Blood Cells and the Complete Blood Count Test of Children in the Hawija City, Kirkuk Governorate

The current study aimed to know the negative effect of children with acute tonsillitis on CBC values and inflammatory indicators. ESR where the study included 50 children whose ages ranged from 5-10 years. Examples of experiment were divided into two groups 25 children for the first group, who were healthy from the injury. As for the second group, they are 25 children with acute tonsillitis. Al -Razi Laboratory, Al -Rafah and Al -Ahly Hospital Laboratory in Al -Hawija district. The current study's findings demonstrated a noteworthy rise in White Blood Cell (WBC) in children with acute tonsillitis compared to healthy children, while the results of the study in Red Blood Cell (RBC) showed a significant increase in healthy people compared to the affected children, while platelet values and values showed PCV is that there are no moral differences between the injured and the healthy, as the results showed that there is a moral rise in random sugar values and ESR values.

Seasonality Disrupted: Post-Pandemic Trends in Otorhinolaryngological Infections.

Background: The COVID-19 pandemic has notably affected the epidemiology of various infectious diseases. The imposed public health measures and disruptions in vaccination programs have potentially altered the patterns of these diseases post pandemic. Objective: To investigate the change in epidemiology of otorhinolaryngological infectious diseases in adult and pediatric patients after the COVID-19 pandemic and the relaxation of public health measures. Methods: A retrospective cohort study was conducted at a large tertiary university otolaryngology department in the south of Germany, examining admissions with specific ICD-10 diagnoses from 2019 to 2023. Data were seasonally categorized and statistically analyzed. Results: A total of 1728 inpatient cases were analyzed. There was a significant increase in otorhinolaryngological infections in the post-pandemic winter of 2022, particularly of peritonsillar abscesses, acute tonsillitis and acute mastoiditis. No significant post-pandemic spike in mononucleosis was observed. The duration of hospitalization was shorter in 2022, and the median age of patients did not change significantly pre- versus post-pandemic. Conclusions: The study indicates a significant post-pandemic rise in otorhinolaryngological infections. Remarkably, the typical "dip" in infections during the summer months was not observed in the post pandemic years, possibly reflecting the impact of the termination of non-pharmaceutical interventions. Mononucleosis was the only infection not following this pattern.

The impact of social restrictions on the incidence and microbiology of severe acute tonsillitis.

We aimed to explore the impact of social distancing on the incidence, severity and microbiology of patients with acute tonsillitis (AT). In this single-centre study, we retrospectively included all patients with AT referred to the Ear-Nose-Throat Department, Aarhus University Hospital, Denmark, in the two years preceding versus the two years after the COVID-19 lockdown in Denmark (11 March 2020). In total, 425 patients were included. The incidence of AT was significantly lower in the post-lockdown period (n = 128) than in the pre-lockdown period (n = 297) (p less-than 0.001). Reduced incidence was observed across all age groups. No significant differences were found in patient characteristics between periods. The proportion of hospitalised patients was significantly lower in the post- than in the pre-lockdown period (36% versus 25%, p = 0.032). Prevalent culture findings were Streptococcus pyogenes (15%), S. anginosus group (11%) and Fusobacterium necrophorum (5%). No statistically significant differences in the relative prevalence of individual bacteria were found between periods. The incidence of patients with AT referred to hospital decreased by 57% in the two-year period after the COVID-19 lockdown compared with the period leading up to the lockdown. Our findings suggest that this decrease mirrored a general decline in AT incidence rather than altered referral patterns. None. The study was approved by the Danish Data Protection Agency (#1-16-02-134-23) and the Danish Patient Safety Authority (#1-45-70-41-23).

Injuries of the oral mucosa. Clinical cases

Background. Often with some infectious diseases, in addition to the typical manifestations, characteristic inflammatory changes are observed on the mucous membranes, which can imitate the course of other diseases. The purpose was to remind dentists and general practitioners about the importance of differential diagnosis of lesions of the oral mucosa in infectious and non-infectious pathologies on the example of clinical cases. Materials and methods. We conducted an empirical, descriptive study of 3 clinical cases of lesions of the oral mucosa in children who underwent inpatient treatment at the Kyiv City Children’s Clinical Infectious Hospital in 2023–2024. Results. In the first clinical case, the manifestation of type 1 diabetes was described, which was accompanied by oral candidiasis that was previously regarded as a suspicion of measles. The second clinical case demonstrates aphthous ulcers in HIV infection, which was previously mistaken for acute tonsillitis in a child. The third case described enteroviral vesicular stomatitis, which by the nature of the elements resembled chicken pox. Conclusions. Lesions of the oral mucosa can mimic the manifestations of common infectious and non-infectious diseases. Therefore, differential diagnosis of lesions of the oral mucosa is extremely important in various fields of medicine and dentistry.

Membranous tonsillitis: Aetiology, prevalence and prescribing patterns in patients with upper respiratory tract infection.

Background Membranous tonsillitis is one of the most common forms of acute tonsillitis in childhood. Although many different microorganisms may cause this disease, clinicians generally consider bacterial agents as a possible cause and prescribe a penicillin-group of antibiotic. This study aimed to determine the aetiology of membranous tonsillitis and prescribing errors. In addition, we investigated the effectiveness of epidemiological, clinical and laboratory parameters and their role in guiding treatment. Methods We did this retrospective study at the paediatric emergency department of a tertiary referral hospital including 423 outpatient children aged 0 to 18 years diagnosed with membranous tonsillitis. Results Group A beta-haemolytic streptococcus was found in 132 (31.2%) patients, Epstein-Barr virus (EBV) in 103 (24.3%), and other viral aetiologies in 188 (44.4%). The prescription rate of antibiotics in the EBV-positive group was 27%, and Downey cells were seen at a rate of 98% in this group. Only 7% of patients with a positive throat culture were started on appropriate antibiotics. Conclusion EBV and group A beta-haemolytic streptococcus were the most common causes of membranous tonsillitis. Throat culture and peripheral blood smears are the most useful tests for paediatric emergency clinicians; these are fast and can help ensure correct diagnosis and guide treatment in almost all patients.

Topical issues of diagnosis and treatment of arthropathy associated with tonsillitis. (Literature review)

The problem of chronic tonsillitis (CT) and its complications remains one of the most urgent in modern otorhinolaryngology today. The high probability of developing associated diseases, such as rheumatic heart disease, nonspecific arthritis and glomerulonephritis, emphasizes the high importance of this nosological unit both in the practice of an otorhinolaryngologist and doctors of other specialties. Reactive arthritis occupies a special place among the complications of CT. Acute rheumatic fever (ARF) used to be the most common disease that was associated with streptococcal tonsillitis and was accompanied by reactive arthritis. Since 1959, patients with ARL have become less common, but cases of "aseptic" arthritis in patients with acute tonsillitis continued to be recorded, however, they did not have any other major criteria to confirm the diagnosis of ARL. This type of arthritis is called "Post-streptococcal reactive arthritis" (PSRA). Despite the fact that this disease has been known since the middle of the XIX century, there is very little information about its etiology and pathogenesis in the literature. The main symptoms of PSRA are usually similar to the articular syndrome in classical reactive arthritis and are clinically manifested by acute asymmetric non-migrating polyarthritis. Laboratory diagnosis of PSRA, in particular, the determination of titers of streptococcal antibodies plays an important role in confirming the diagnosis. A special place is occupied by the differential diagnosis of PSRA with rheumatic diseases (RH). The main diagnostic laboratory markers of RH are antinuclear antibodies, rheumatoid factor and antibodies to citrullinated proteins. Joint syndrome in PSRA is often stopped when nonsteroidal anti-inflammatory drugs (NSAIDs) are prescribed only in combination with antibacterial drugs. If arthritis does not respond to long-term treatment with antibiotics and NSAIDs, and especially if the patient has a history of recurrent CT, a planned tonsillectomy is required to prevent the development of a chronic form of tonsillitis-associated arthritis. The article presents an analytical review of domestic and foreign publications on the topic of CT complicated by reactive arthritis. The possible diagnostic methods necessary to confirm the diagnosis and exclude a wide range of arthritis of a different etiology are described.

Pregnancy outcomes in patients with undifferentiated connective tissue disease: An observational cohort prospective study

Background. Undifferentiated connective tissue disease is the subject of research in a large number of medical specialties, as it leads to an aggravated course of various diseases. In the presence of this pathology during pregnancy, the incidence of such complications as preeclampsia, gestational diabetes, and placental abruption increases. Failure to carry a pregnancy to term can be associated with various causes, including the activity of myocytes, while the pathology in question involves the connective tissue of the uterus. In this connection, it seems necessary to study the impact of undifferentiated connective tissue disease on pregnancy outcomes in order to administer timely treatment.Objectives. To assess how undifferentiated connective tissue disease affects the risk of failure to carry a pregnancy to term.Methods. An observational cohort prospective study was conducted among pregnant women who were under antenatal care in 2021–2022. The study was performed at the premises of the Clinical Maternity Hospital of Minsk Region (Republic of Belarus). The patients were divided into two groups: an exposed group comprising 59 patients with diagnosed undifferentiated connective tissue disease and a nonexposed group comprising 59 patients without this pathology. Both groups were divided into subgroups according to the obstetric outcome. The exposed group included a subgroup of 17 undifferentiated connective tissue disease patients who had failed to carry pregnancy to term (miscarriage and preterm labor) and a subgroup of 42 undifferentiated connective tissue disease patients with delivery at term. The nonexposed group included a subgroup of five women without undifferentiated connective tissue disease who had failed to carry pregnancy to term (miscarriage and preterm labor) and a subgroup of 54 women without undifferentiated connective tissue disease and with delivery at term. According to ICD-10, abortive outcomes occurred before 21 weeks and six days gestation; labor that occurred at 22–36 weeks and six days gestation was considered preterm, whereas in the case of delivery at term, the baby was born at 37–41 weeks and six days gestation. The obstetric, gynecological, and somatic history, as well as pregnancy outcomes, were analyzed. Statistical processing of data was performed using the following software: Statistica 12.0 (StatSoft, USA), Microsoft Excel 2016, Epi InfoTM 7.2.6.0 (USA), and MedCalc 15.8 (MedCalc Software, Belgium). In hypothesis testing, differences were considered statistically significant at p < 0.05.Results. In the group of undifferentiated connective tissue disease patients, metrorrhagia was statistically significantly more common than in the patients without undifferentiated connective tissue disease: 18 out of 59 (30.5 %) and six out of 59 (10.2 %), respectively, p = 0.012. The obstetric history revealed no statistically significant intergroup differences, p > 0.05. In the undifferentiated connective tissue disease patients, the following diseases were statistically significantly more common: myopia, spinal scoliosis, lower limb varicose veins, chronic tonsillitis, mitral valve prolapse, and iron deficiency anemia (p < 0.05). The incidence of new cases of failure to carry a pregnancy to term in the cohort during the observation period amounted to 18.6 % for the patients in both groups. The pregnancy ended prematurely in 17 out of the 59 undifferentiated connective tissue disease patients (28.8 %) and in five out of the 59 patients without undifferentiated connective tissue disease (8.5 %), relative risk of 3.4 (95 % CI:1.3–8.6), p = 0.005.Conclusion. Undifferentiated connective tissue disease increases the risk of failure to carry a pregnancy to term by 3.4 times. Timely diagnosis and treatment of undifferentiated connective tissue disease at the stage of preconception preparation can reduce the incidence of failure to carry a pregnancy to term.

Importance of biomarkers in streptococcal acute tonsillitis & peritonsillar abscess.

Background & objectives Acute tonsillitis is a disease that can often be cured with medical treatment. However, complications may occur during this disease process. One of these complications is peritonsillar abscess. In recent years, biomarkers have been frequently used in the diagnosis of diseases. The aim of the study was to reveal whether peritonsillar abscess develops after acute tonsillitis, and acute tonsillitis can be differentiated using biomarkers and which biomarker has higher predictive value for this differentiation. Methods The control group consisted of individuals who were operated for septoplasty in the otolaryngology clinic, and the acute tonsillitis group consisted of individuals diagnosed with acute tonsillitis in the same clinic. Both groups were statistically compared in terms of mean platelet volume (MPV), neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), systemic immune inflammation index (SII), infection discrimination index (IDI), plateletcrit (PCT) and lymphocyte to monocyte ratio (LMR) biomarkers. Statistically, significant biomarker values were compared between the subgroups in the tonsillitis group of those who had only acute tonsillitis and those who had peritonsillar abscess due to acute tonsillitis. Receiver operating characteristics (ROC) curve analysis was performed on biomarkers for their ability to predict the presence of peritonsillar abscess. Results When the individuals who had only acute tonsillitis and those who had acute tonsillitis with peritonsillar abscess were compared in terms of biomarkers, there was a statistically significant difference between the mean MPV, SII and PCT (P=0.010, 0.021, 0.023, respectively). ROC analysis was performed to calculate the sensitivity and specificity of MPV, PCT and SII for the diagnosis of acute tonsillitis with peritonsillar abscess (sensitivity-specificity for MPV 51.9-72.7%, for SII 94.2-32.7%, for PCT 71.2-50.9%, respectively). Interpretation & conclusions MPV, SII and PCT biomarkers may be useful to help clinicians predict peritonsillar abscess due to acute tonsillitis.

Clinical and economic assessment of using IRS®19 for the treatment and prevention of acute respiratory infections in children

Objective: to perform pharmacoeconomic analysis of the feasibility of using topical bacterial lysate in the form of nasal spray (IRS®19) for the treatment and prevention of upper respiratory tract infections in pediatric population in comparison with other drugs registered in Russia, belonging to the class of topical interferons.Material and methods. Based on the Rosstat data and information from open sources, the population of patients with acute respiratory infections (ARI) was calculated. Considering the Russian clinical recommendations “Acute respiratory viral infection (ARVI)” and “Acute tonsillitis and pharyngitis (acute tonsillopharyngitis)”, the direct medical costs of providing medical care to specialized patients were determined. Direct costs on the part of parents included all costs for purchasing medicines for basic or concomitant therapy. Direct costs on the part of the healthcare system and the state included the costs of providing medical care at the outpatient stage. Direct non-medical costs included payments for disability leaves, indirect costs – lost gross domestic product (GDP) due to absence from work.Results. The total costs of the healthcare system and the state for 1 AVI patient are 42,472 rubles in case of uncomplicated course and 70,649 rubles in case of complicated course. In case of IRS®19 application from the first day of the disease, it is possible to reduce its duration by more than two-fold. Thus, the costs of medical care amount to 2,078 rubles. Payments for disability leaves by the Social Fund of Russia will amount to 2,287 rubles, and the lost GDP – 9,148 rubles (total costs 13,513 rubles).Conclusion. For the first time in Russian economic conditions, the use of IRS®19 for ARI treatment and prevention in children was evaluated. IRS®19 application from the first symptoms of the disease allows refusing the use of topical interferons, reduces the duration of symptoms and the need for prescription of antitussives, vasoconstrictors, and antibiotics.

Clinical and economic assessment of using topical bacterial lysate Imudon® for the treatment and prevention of acute upper respiratory tract infections in children

Objective: pharmacoeconomic analysis of the feasibility of using topical bacterial lysate Imudon® for the treatment and prevention of acute upper respiratory tract infections in the pediatric population in comparison with other medicines belonging to the class of topical antiseptics.Material and methods. For the population calculated on the basis of Rosstat data, taking into account the Russian clinical recommendations "Acute respiratory viral infection (ARVI)" and "Acute tonsillitis and pharyngitis (acute tonsillopharyngitis)", the direct medical costs of medical care were determined. The cost of basic therapy of 1 case of acute respiratory infection (ARI) with symptoms of pharyngitis was calculated for two variants of clinical course: favorable (when ARI proceeds without complications and the patient does not need to be prescribed antibacterial drugs), and unfavorable (when confirmed bacterial infection joins and antibiotics are required). The indirect costs of child care are associated with lost gross domestic product (GDP). In estimating the GDP shortfall, it was assumed that the parent does not contribute to the country’s GDP during the entire childcare period.Results. GDP per capita for 2022 amounted to 2853.13 rubles per day. Thus, with a favorable course of the disease, indirect costs will be 19,972 rubles, and with an unfavorable course – 39,944 rubles. The total costs of the healthcare system and the state for 1 ARI patient are 32,192 rubles in case of favorable course and 71,644 rubles in case of unfavorable course. Imudon® administration allows reducing direct costs of parents for purchase of medicines for treatment of 1 ARI case by 23.6% compared to the therapeutic strategy associated with the use of local antiseptics.Conclusion. For the first time in Russian economic conditions, the use of Imudon® for the treatment and prevention of acute upper respiratory tract infections in children was evaluated. Its use from the first ARI symptoms allows refusing the use of local antiseptics, shortens the duration of the disease symptoms, and reduces the need for antibiotics, i.e. is feasibleable compared to local antiseptics.

Role of OM-85 BV in the prevention of recurrent acute tonsillitis: a retrospective study and literature review

BackgroundThis study aims to assess the effectiveness of OM-85 BV in treating recurrent acute tonsillitis in children and adults during the first year after treatment, as well as to identify response predictors.ResultsThe study included 92 patients, and there was a significant decrease in the number of acute tonsillitis cases after OM-85 BV treatment (p < 0.001). Exposure to tobacco smoke predicts non-response or partial response to treatment (OR 5.24, p = 0.005, 95% CI 1.646–16.671/OR 4.57, p = 0.014, 95% CI 1.362–15.339).ConclusionsThe study concludes that OM-85 BV is effective in preventing new episodes of tonsillitis in patients with a history of recurrent acute tonsillitis. Patients exposed to tobacco smoke tend to have a poorer response to treatment.

Routine Histopathology of Tonsillectomy Specimens, Is It Necessary? A Prospective Observational Study

Routine histopathology of tonsillectomy specimens is not standard practice due to cost and resource constraints. This study aimed to evaluate the prevalence of abnormal histopathologies in tonsillectomy specimens to determine the necessity of routine histopathology. A prospective observational study was conducted from January 2014 to August 2016 at a general tertiary care center after approval of Institutional Ethics Committee (IEC). Patients scheduled for tonsillectomy surgery as per the AAOHNS 2011 criteria were included in the study. All tonsillectomy specimens were sent for histopathology, and abnormal findings were documented. Statistical analysis was performed. A total of 111 patients were enrolled in this study, and 222 tonsillectomy specimens were analyzed. The most common finding was chronic tonsillitis, which justified the selection criteria in 91.89% of patients. Two patients with chronic tonsillitis were also found to have actinomycosis present on the surface without parenchymal tissue reaction. Abnormal histopathological findings were observed in 9 (8.10%) of patients, leading to further investigations or treatment in 8 cases. These abnormalities included chronic granuloma, non-Hodgkin's lymphoma, early squamous cell carcinoma, and one choristoma. Tonsillar asymmetry, recent onset of symptoms and older age were found to be significantly correlated with abnormal histopathology and malignancy. Routine histopathology in tonsillectomy specimens helps to identify important findings that may require additional treatment. Based on the study we strongly recommend routine histopathology of tonsillectomy specimen. When significant cost constraints exist, risk-based approach can be adopted. Factors such as older age, asymmetry of tonsils, referred otalgia, duration of symptoms (recent onset) and a history of addiction should be considered for proceeding with histopathology.

Application of next-generation sequencing in acute tonsillitis complicated with descending necrotizing mediastinitis: A case report.

Descending necrotizing mediastinitis (DNM) is a rare but serious complication of oral and cervical infections that is associated with high mortality because diagnosis can be difficult or delayed. Early diagnosis and accurate identification of the causative pathogen can significantly reduce mortality, and are critical for the management of these patients. A 56-year-old female was admitted with a sore throat and fever. The initial diagnosis was acute tonsillitis, but she was transferred to the intensive care unit after developing dyspnea. Pleural effusion and mediastinal lesions were detected by computed tomography, and a diagnosis of DNM was confirmed by laboratory tests. Initial treatment consisting of ceftriaxone and vancomycin with chest tube drainage were not effective. Thoracic surgery was performed to completely remove the "moss" tissue, blood clots, and pus. Next-generation sequencing was then performed, and the anti-infective treatment was changed to imipenem and linezolid based on these results. Eventually, the patient's symptoms were controlled, all vital signs were stable, and she was successfully transferred out of the intensive care unit. Next-generation sequencing is a rapid and accurate method for identification of pathogens that can provide a basis for early treatment of DNM, thereby improving patient prognosis and reducing mortality.
