The Clinical Significance of Tonsillar Actinomyces in Histopathological Samples after Tonsillectomy. Pathogens 2023; 12:1384. [PMID: 38133269 PMCID: PMC10745963 DOI: 10.3390/pathogens12121384] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2023] [Revised: 11/19/2023] [Accepted: 11/21/2023] [Indexed: 12/23/2023] Open
Abstract
BACKGROUND Actinomyces is a genus of Gram-positive anaerobic or microaerophilic bacteria with a branched filamentous shape. Their presence in tonsil tissue is usually determined by histopathological examination. In the crypts of removed tonsils, they have a prevalence ranging from 0.8% to 61.6%. The role of Actinomyces in diseases of the palatine tonsils is not clearly defined. The aim of the study was to determine the importance of Actinomyces in the pathology of palatine tonsils and to assess the impact of these bacteria on the clinical data. METHODS the retrospective analysis of the histopathological findings of patients undergoing tonsillectomy in our hospital from January 2017 to the end of December 2019 was performed in terms of the occurrence of Actinomyces. The data were collected based on the medical history. The study included 481 patients aged 3-82 years. From the study group, 100 adult patients were randomly selected, and a telephone survey was conducted. The questions included the co-occurrence of bronchial asthma, halitosis, tonsilloliths, and cigarette smoking. The questions were related to the complications following tonsillectomy and the severity of postoperative pain. Existence of a relationship was investigated between occurrence of tonsillar Actinomyces and age, sex, body mass index, and medical condition (obstructive sleep apnea, chronic palatine tonsillitis), respectively. The size of the removed tonsils was assessed and compared depending on the presence of the bacteria. RESULTS patients aged 18 years and older had a higher probability of presenting Actinomyces. The estimated odds ratio for the presence of the bacteria per year of age was 1.023 [1.007, 1.041]. No statistically significant results were found for the other variables. The co-occurrence of the bacteria and halitosis was close to statistical significance (p = 0.064). CONCLUSIONS multivariate analysis of the role of Actinomyces in tonsillar pathology showed that these microorganisms should be considered saprophytes of the oropharyngeal microflora that had no significant relationship with the pathology of palatine tonsils. Further studies on their influence on halitosis are warranted.

Abstract
Actinomycosis of the tonsils is uncommon even though the causative organisms are normal commensal of the oropharyngeal tract that may colonise the tonsillar crypts with resultant infection in apparently healthy individuals. Diagnosis is often incidental in tonsillectomy specimens sent to the pathology laboratory for varied diseases. This is a 10-year study of tonsillectomy specimens diagnosed with actinomycosis. Specimens were formalin-fixed and paraffin processed and stained with haematoxylin and eosin, gromott methenamine silver and periodic acid-Schiff. Four cases of tonsillar actinomycosis were diagnosed from a total of 772 tonsillectomy specimens. Histologically, characteristic oeosinophilic granules with peripheral radial protuberances surrounded by microabscesses were seen. Tonsillar actinomycosis is often an incidental diagnosis; however, a high index of suspicion should be entertained in patients with recurrent tonsillitis and/or tonsillar hypertrophy of unknown cause.

Characteristics of salivary microbiota in children with obstructive sleep apnea: A prospective study with polysomnography. Front Cell Infect Microbiol 2022; 12:945284. [PMID: 36105146 PMCID: PMC9465092 DOI: 10.3389/fcimb.2022.945284] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2022] [Accepted: 08/08/2022] [Indexed: 11/13/2022] Open
Abstract
ObjectivesThe present study aimed to investigate the characteristics of salivary microbiota of children with obstructive sleep apnea (OSA) and to assess longitudinal alterations in salivary microbiota before and after adenotonsillectomy.MethodsA set of cross-sectional samples consisted of 36 OSA children (17 boys and 19 girls, 7.47 ± 2.24 years old) and 22 controls (9 boys and 13 girls, 7.55 ± 2.48 years old) were included in the study, among which eight OSA children (five boys and three girls, 8.8 ± 2.0 years old) who underwent treatment of adenotonsillectomy were followed up after 1 year. Saliva samples were collected, and microbial profiles were analyzed by bioinformatics analysis based on 16S rRNA sequencing.ResultsIn cross-sectional samples, the OSA group had higher α-diversity as estimated by Chao1, Shannon, Simpson, Pielou_e, and observed species as compared with the control group (p < 0.05). β-Diversity based on the Bray–Curtis dissimilarities (p = 0.004) and Jaccard distances (p = 0.001) revealed a significant separation between the OSA group and control group. Nested cross-validated random forest classifier identified the 10 most important genera (Lactobacillus, Escherichia, Bifidobacterium, Capnocytophaga, Bacteroidetes_[G-7], Parvimonas, Bacteroides, Klebsiella, Lautropia, and Prevotella) that could differentiate OSA children from controls with an area under the curve (AUC) of 0.94. Linear discriminant analysis effect size (LEfSe) analysis revealed a significantly higher abundance of genera such as Prevotella (p = 0.027), Actinomyces (p = 0.015), Bifidobacterium (p < 0.001), Escherichia (p < 0.001), and Lactobacillus (p < 0.001) in the OSA group, among which Prevotella was further corroborated in longitudinal samples. Prevotella sp_HMT_396 was found to be significantly enriched in the OSA group (p = 0.02) with significantly higher levels as OSA severity increased (p = 0.014), and it had a lower abundance in the post-treatment group (p = 0.003) with a decline in each OSA child 1 year after adenotonsillectomy.ConclusionsA significantly higher microbial diversity and a significant difference in microbial composition and abundance were identified in salivary microbiota of OSA children compared with controls. Meanwhile, some characteristic genera (Prevotella, Actinomyces, Lactobacillus, Escherichia, and Bifidobacterium) were found in OSA children, among which the relationship between Prevotella spp. and OSA is worth further studies.

Abstract
Actinomycosis is a chronic suppurative infection that can develop almost anywhere in the body. Cervicofacial actinomycosis is the most common form of the disease. We report a case of tonsillar actinomycosis that causes massive, asymmetric enlargement of tonsil and mimics the neoplasia. The most common cause of asymmetric tonsil hypertrophy is tonsillar squamous cell carcinoma and lymphomas. Tonsillar actinomycosis is a rare entity that should be kept in mind, if cases cannot be clarified with clinical and laboratory findings, when radiological findings are suspicious about malignancy.

Abstract
OBJECTIVE To better characterize associations between Actinomyces and tonsillolith versus nontonsillolith tonsillectomy specimens. STUDY DESIGN Bi-institutional retrospective case-case study. SETTING University and county hospital. SUBJECTS AND METHODS Adult patients with a clinical history of tonsilloliths who underwent tonsillectomy from January 2006 to December 2018 were included. Patients undergoing tonsillectomy for tonsillar hypertrophy and chronic tonsillitis were identified as comparative cases. Similarly, patients with ipsilateral oropharyngeal cancer (OPC) who underwent contralateral tonsillectomy of a normal-appearing tonsil for prophylaxis against a second primary cancer were also included as comparative cases. RESULTS The study population comprised 134 patients who underwent tonsillectomy: 62 tonsillolith and 72 nontonsillolith (tonsillar hypertrophy, n = 30; chronic tonsillitis, n = 30; normal-appearing contralateral tonsil in patients with ipsilateral OPC, n = 12). Actinomyces was reported in 11% of the patients with tonsilloliths on initial pathology reports but in 95% after re-evaluation (n = 54 of 57). Actinomyces prevalence was significantly higher in patients with tonsilloliths as compared with patients with recurrent tonsillitis (73%, n = 22 of 30, P < .001) and normal-appearing contralateral tonsils in patients with ipsilateral OPC (58%, n = 7 of 12, P < .001). Actinomyces prevalence was not significantly different between patients with tonsilloliths and tonsillar hypertrophy (83%, n = 25 of 30, P = .11). CONCLUSION The prevalence of Actinomyces in tonsillolith tonsil specimens is high; however, Actinomyces routinely colonizes nontonsillolith tonsil specimens. Therefore, Actinomyces is unlikely to be the primary driver of tonsillolith pathogenesis, and Actinomyces-targeted treatment of tonsilloliths may not be effective. Treatment strategies addressing tonsilloliths should be further investigated.

Abstract
Introduction Tonsillitis is a very common disease in children. Understanding the microbiology and pathology of chronic tonsillitis is an important step in its management. The aim of the study was to describe the microbiological profile of core tonsillar tissue in chronic tonsillitis in children. Materials and methods Children under 16 years of age with chronic tonsillitis were recruited in the descriptive study. Children with recurrent tonsillitis and recurrent tonsillitis with obstructive symptoms were included. Children who underwent tonsillectomy for obstructive symptoms alone and those who received antibiotics for at least one month prior to surgery were excluded from the study. Dissection and the snare method of tonsillectomy were done on all children. The operated specimen was cut into two halves in a sterile container. The core of the tonsillar tissue was swabbed with two sterile cotton-tipped swabs and sent for the microbiological evaluation of aerobes and anaerobes. The tonsillar tissue was sent for a histopathological examination. Results A total of 106 children were operated for chronic tonsillitis in one year. The mean age of children included in this study was 9.4 years. The duration of symptoms due to tonsillar disease ranged from four weeks to 28 months. There were 48 males and 58 females. Recurrent tonsillitis was the most common indication for tonsillectomy in all children. A total of 301 aerobes and 171 anaerobic microorganisms were isolated from 106 children with chronic tonsillitis. The aerobic bacterial species most often isolated was Streptococcus viridans, which was present in 83 children followed by Group A, β-hemolytic Streptococci in 67 children. The anaerobic bacterial most often isolated was Peptococcus species in 49 children. Polymicrobial aerobic and anaerobic flora were present in all tonsillar specimens, yielding an average of 4.1 isolates per specimen. The histopathological examination revealed chronic tonsillitis with reactive follicular hyperplasia in all (100%) children. Actinomycosis was associated with non-specific reactive follicular hyperplasia in four specimens. Conclusion Polymicrobial aerobic and anaerobic flora are identified in deep tonsillar tissue in children with tonsillitis. The identification of bacterial isolates from the core tissue in recurrent tonsillitis could dictate the management of chronic tonsillitis. The histopathological examination of the core tissues of the tonsils helps in an accurate identification of organisms that are difficult to culture.

Is tonsillectomy mandatory for asymmetric tonsils in children? A review of our diagnostic tonsillectomy practice and the literature. Int J Pediatr Otorhinolaryngol 2018; 110:57-60. [PMID: 29859588 DOI: 10.1016/j.ijporl.2018.04.027] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/05/2018] [Revised: 04/26/2018] [Accepted: 04/27/2018] [Indexed: 12/01/2022]
Abstract
INTRODUCTION Diagnostic tonsillectomy is performed to exclude malignancy. It is associated with a post-operative hemorrhage rate of 3.5%, (1) which is more dangerous in small children. No previous case series for asymmetrical tonsils have detected tonsil lymphoma.(2-6) We aimed to review our local diagnostic tonsillectomy practice. METHOD The authors reviewed the clinical notes and histological results for all diagnostic tonsillectomies carried out from June 2013 to June 2016. RESULTS We recorded data for 168 patients. There were four post-operative bleeds and one return to theatre. Bilateral tonsillectomies accounted for 152 operations (90.5%). Lymphoid hyperplasia accounted for 95% of histological diagnosis with no malignancies found. Pre-operative tonsil grading demonstrated no statistically significant association with histological tonsil weight difference (ANOVA p = 0.10). Actinomyces colonisation had little affect on tonsil weight difference when we compared patients with bilateral colonisation and no colonisation (t-test p = 0.540) and between tonsils in patients with unilateral tonsil Actinomyces colonisation (paired t-test p = 0.448). Recurrent tonsillitis was more prevalent in patients with Actinomyces colonisation than OSA/sleep disordered breathing (39% vs 15%). CONCLUSION A literature search yielded five smaller case series of palatine tonsil asymmetry in children with no malignancy found.(2-6) Case-control studies report tonsillar asymmetry as the most common presenting symptom (73%) in tonsillar lymphoma.(7) This enlargement usually occurs rapidly within 6 weeks with new obstructive or systemic B-type symptoms.(3) A Turkish epidemiological study found asymmetrical tonsils in 1.7% of the healthy paediatric population.(8) We therefore estimate there to be over 210,000 children with asymmetrical tonsils in the UK. With an unreliable grading system, we believe asymmetrical tonsils in isolation, unchanged for over 6 weeks may not warrant tonsillectomy.

Abstract
Objective Waldeyer's lymphatic ring consists of group of tonsils located over the posterior oropharyngeal wall. The palatine tonsils are largest tonsil. The present study was aimed to evaluate the significance of lymphoid hyperplasia, lymphocyte infiltration with and without defect in the surface epithelium in chronic tonsillitis (CT) and chronic adenotonsillar hypertrophy (CAH) in resected tonsillectomy and adenotonsillectomy specimens. Materials and Methods A total of 85 patients were included in the study. Fifty-one cases underwent bilateral tonsillectomy and 34 cases underwent adenotonsillectomy. Results The lymphoid hyperplasia was higher in CAH (30/34; 88.24%) as compared to CT (26/50; 52%). Lymphocyte infiltration with or without defect in the surface epithelium was common in CT. The histopathologic criteria of lymphoid hyperplasia and lymphocyte infiltration with or without defect in the surface epithelium showed a statistically significant difference between CT and CAH. Conclusion CT and CAH may be differentiated on the basis of reliable histopathological criteria. Punch biopsy can be performed to avoid CT complication if the clinical diagnosis is true. Choristomas can be clinically confused with true neoplasms, if large in size.

Abstract
Immunoglobulin (Ig)A, IgM, and IgG antibodies against Penicillium notatum, Aspergillus niger, Stachybotrys chartarum, and satratoxin H were determined in the blood of 500 healthy blood donor controls, 500 random patients, and 500 patients with known exposure to molds. The patients were referred to the immunological testing laboratory for health reasons other than mold exposure, or for measurement of mold antibody levels. Levels of IgA, IgM, and IgG antibodies against molds were significantly greater in the patients (p < 0.001 for all measurements) than in the controls. However, in mold-exposed patients, levels of these antibodies against satratoxin differed significantly for IgG only (p < 0.001), but not for IgM or IgA. These differences in the levels of mold antibodies among the 3 groups were confirmed by calculation of z score and by Scheffé's significant difference tests. A general linear model was applied in the majority of cases, and 3 different subsets were formed, meaning that the healthy control groups were different from the random patients and from the mold-exposed patients. These findings indicated that mold exposure was more common in patients who were referred for immunological evaluation than it was in healthy blood donors. The detection of antibodies to molds and satratoxin H likely resulted from antigenic stimulation of the immune system and the reaction of serum with specially prepared mold antigens. These antigens, which had high protein content, were developed in this laboratory and used in the enzyme-linked immunosorbent assay (ELISA) procedure. The authors concluded that the antibodies studied are specific to mold antigens and mycotoxins, and therefore could be useful in epidemiological and other studies of humans exposed to molds and mycotoxins.

Abstract
Objective This study aimed to investigate the incidence of Actinomyces in tonsillar tissues of patients undergoing tonsillectomy and to determine the association among tonsillar volume, preoperative antibiotic use, and presence of Actinomyces in tonsil tissues. Methods In this study, 142 patients who underwent tonsillectomy in last four years were included. Of the total patients, 97 (66.9%) were children and 47 (33.1%) were adults. The patients' age, sex, preoperative antibiotic use, tonsillar volume, and presence of actinomyces in tonsillar tissues were recorded. Results Actinomyces was identified in tonsillar tissues of 16 (16.4%) pediatric and 21 (44.6%) adult patients. Of all pediatric patients positive for Actinomyces, 13 were males and three were females whereas of all adult patients positive for actinomyces, 14 were males and seven were females. Tonsillar tissue volumes in both pediatric and adult patients positive for Actinomyces were statistically higher than the Actinomyces negative ones. Antibiotic use was higher and the incidence of Actinomyces was lower in pediatric patients than in adult patients positive for Actinomyces. Conclusion Our study results revealed that Actinomyces was prominent in adult patients with tonsillar hypertrophy. In addition, the frequent use of antibiotic decreased the incidence of Actinomyces in tonsillar tissues.

Abstract
Hypertrophy and recurrent tonsillitis are common indications of tonsillectomy. However, the pathological reports are similar, regardless of clinical aspects. Objective Search for histopathological changes that differentiate palatine tonsils operated because of hypertrophy vis-à-vis those operated because of recurrent tonsillitis. Method A prospective cross-sectional descriptive study involving 46 children divided into group I - 22 with hypertrophy; and group II - 24 with recurrent tonsillitis, in the period between 2010 and 2012, in a public hospital. We evaluated clinical and histopathological features (lymph follicles, germinal centers, fibrosis, necrosis, reticulation, infiltration by plasma cells and neutrophils). Results The patients' ages ranged between 2 and 11 years (5.17 ± 2.28). In group I, half of the patients had had the latest infection at seven months or more, and all with obstruction degree greater than 3 (≥ 50%). In group II, all had had the latest infection at less than seven months, and most with obstruction degree below 4 (≤ 75%). There was a statistically significant difference in the degree of obstruction (p = 0.0021) and number of germinal centers (p = 0.002) was higher in group I. Conclusion This study suggests that the number of germinal centers is the only histopathological criterion that can be used to differentiate the two groups.

Abstract
Purpose To detect predominant bacteria associated with radicular cysts and discuss in light of the literature. Material and methods Clinical materials were obtained from 35 radicular cysts by aspiration. Cultures were made from clinical materials by modern laboratory techniques, they underwent microbiologic analysis. Results The following are microorganisms isolated from cultures: Streptococcus milleri Group (SMG) (23.8%) [Streptococcus constellatus (19.1%) and Streptococcus anginosus (4.7%)], Streptococcus sanguis (14.3%), Streptococcus mitis (4.7%), Streptococcus cremoris (4.7%), Peptostreptococcus pevotii (4.7%), Prevotella buccae (4.7%), Prevotella intermedia (4.7%), Actinomyces meyeri (4.7%), Actinomyces viscosus (4.7%), Propionibacterium propionicum (4.7%), Bacteroides capillosus (4.7%), Staphylococcus hominis (4.7%), Rothia denticariosa (4.7%), Gemella haemolysans (4.7%), and Fusobacterium nucleatum (4.7%). Conclusions Results of this study demonstrated that radicular cysts show a great variety of anaerobic and facultative anaerobic bacterial flora. It was observed that all isolated microorganisms were the types commonly found in oral flora. Although no specific microorganism was found, Streptococcus spp. bacteria (47.5%) – especially SMG (23.8%) – were predominantly found in the microorganisms isolated. Furthermore, radicular cysts might be polymicrobial originated. Although radicular cyst is an inflammatory cyst, some radicular cyst fluids might be sterile.

Abstract
INTRODUCTION Actinomycosis is a chronic infectious disease caused by anaerobic, gram-positive microorganisms from the order of Actinomyce or Propionobacterium. The disease manifests iself mostly in cervicofacial form and less frequently in thoracic and abdominal form. The study was aimed at reviewing clinical manifestations and therapeutic approaches in treatment of patients with Actinomycosis. MATERIAL AND METHODS The study sample consisted of four patients with different clinical manifestations of Actinomycosis, who had been treated at the Institute for Infectious and Tropical Diseases in Belgrade in 2002, 2003, 2006 and 2008. RESULTS Four patients with Actinomycosis were treated during the above mentioned periods of time. One patient had kidney Actinomycosis, which developed into generalized Actinomycosis. Two patients had the most common cervical form, while the forth one had abdominal form; all patients received Penicillin G followed by Ampicillin, during the period of four weeks to up to a year. CONCLUSION Actinomycosis is a rare disease, which imposes great diagnostic dilemmas. The treatment of this disease requires long term use of antibiotics.

Abstract
BACKGROUND Actinomycosis of the tonsils has been reported in a variable percentage of tonsil specimens by other authors. This study determines the incidence of actinomyces in the palatine tonsil and evaluates the clinical diagnoses and histopathological features of tonsillectomy specimens. METHODS In a retrospective study, 204 patients who had undergone tonsillectomy for recurrent tonsillitis (group A) and for sleep apnea without a history of recurrent tonsillitis (group B) were enrolled. RESULTS The prevalence rate was significantly higher in the adult compared with the pediatric population. The prevalence of tonsillar actinomycetes colonization was higher in patients who had undergone tonsillectomy for recurrent tonsillitis (43.9%) than in patients who had undergone tonsillectomy for obstructive sleep apnea (26.3%). The prevalence did not differ by sex of patient. Histopathological analysis of resected tonsils did not show active tissue infection. There was a statistically significant relationship between the presence of actinomycosis and age, with a greater occurrence of actinomycosis in adult patients. CONCLUSION Although actinomyces colonization is more prevalent in patients with recurrent tonsillitis than sleepdisordered breathing, but the presence of actinomyces does not indicate any active disease.

The role of the actinomyces in obstructive tonsillar hypertrophy and recurrent tonsillitis in pediatric population. Int J Pediatr Otorhinolaryngol 2011; 75:391-4. [PMID: 21227516 DOI: 10.1016/j.ijporl.2010.12.014] [Citation(s) in RCA: 12] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/02/2010] [Revised: 10/23/2010] [Accepted: 12/14/2010] [Indexed: 11/25/2022]
Abstract
OBJECTIVE To determine the prevalence of tonsillar Actinomyces in subjects with recurrent tonsillitis and those with obstructive tonsillar hypertrophy, and to determine the association between the presence of Actinomyces and tonsillar volume, and crypt abscess. SUBJECTS AND METHODS A prospective designed cross-sectional study consisted of 90 children subjects who underwent tonsillectomy or adenotonsillectomy for recurrent tonsillitis and obstructive tonsillar hypertrophy. The subjects of recurrent tonsillitis (Group A) and obstructive tonsillar hypertrophy (Group B) were compared to the presence of Actinomyces. The relationship between the presence of Actinomyces and the presence of crypt abscess, and tonsillar volume were also compared. RESULTS Actinomyces was found to be significantly more prominent in obstructive tonsillar hypertrophy group (61.5%) compared to recurrent tonsillitis group (26.6%) (p<0.001). Additionally, the mean tonsillar volume was significantly higher in tonsils with Actinomyces than those without (p<0.001). The histopathological study revealed that there was no significant inflammatory response to the existence of Actinomyces. CONCLUSION According to the presented study, Actinomyces was seen more prominent in subjects with obstructive tonsillar hypertrophy compared those with recurrent tonsillitis. Furthermore Actinomyces had a pathological influence on tonsil size. This study showed there was a significant relation between Actinomyces and enlargement of tonsillar tissue. However, how causes tonsillar hypertrophy is not understood yet in tonsillar disease.

Abstract
The purpose of this report was to present an unusual case of an unilateral tonsillar hypertophy caused by actinomycosis. It is an infrequent bacterial infection nowadays. Only five such cases have been reported up to now. Diagnosis is difficult, because there are not specific diagnostic procedures. Medical treatment consists of surgical excision of tonsils and postoperative antibiotic therapy.

Abstract
OBJECTIVE Systemic bacterial and fungal infections may sometimes present local manifestations within otolaryngological district whose early detection may be useful in establishing a correct diagnosis and more appropriate treatment. This paper reviews certain systemic bacterial and fungal diseases presenting ENT manifestations in the pediatric population from an otolaryngological perspective. METHODS A medline searching for specific issues was performed in order to achieve more information as possible with regards to ENT manifestation of systemic bacterial and fungal infections. Limits for pediatric age were used. Two separate sections for bacterial and fungal disease are included. The section on systemic bacterial infections considers cat-scratch disease, Lyme borreliosis, actinomycosis, Lemierre's syndrome and congenital syphilis, and the section on systemic fungal infections includes candidiasis, aspergillosis and histoplasmosis. CONCLUSIONS Pediatricians and ear, nose and throat (ENT) specialists, approaching head and neck disorders in children, should therefore consider them among the possible differential diagnoses. This means that physicians need to recognize the first head and neck manifestations of systemic infections promptly in order to be able to treat them efficaciously and avoid the dangerous systemic spreading of the infective process.

Abstract
OBJECTIVE To determine the prevalence of tonsillar actinomycosis in pediatric tonsillectomies performed for sleep disordered breathing (SDB) compared with recurrent infective tonsillitis. METHODS All tonsillectomy specimens performed in a pediatric otolaryngology practice over a 10-year period were sent to the same pathology laboratory for histological analysis for the prevalence of Actinomyces. A database of 1213 children was generated and analyzed to determine any significant differences in Actinomyces carriage between children with a primary diagnosis of sleep disordered breathing, compared with recurrent tonsillitis. Statistical analysis was performed using a 2 way contingency table, and significance analyzed via chi-squared and Fisher's exact test. RESULTS Four hundred and sixty five children aged less than 16 underwent tonsillectomy for recurrent tonsillitis and 748 for SDB. Actinomyces were identified in 68 of the group with recurrent tonsillitis (14.6%) and in 153 of the group with SDB (20.5%). This difference was statistically significant with p=0.009 on two-tail Fisher's exact test. CONCLUSION There was a statistically significant higher rate of Actinomyces colonization in children undergoing tonsillectomies for SDB compared to recurrent tonsillitis.

[Tonsillar actinomycosis as a rare cause of oral malodor. Diagnosis beyond a gastroenterologist's nose]. ACTA ACUST UNITED AC 2009; 104:480-3.

Abstract
BACKGROUND Up to 30% of patients seen by dentists suffer from oral malodor. Part of them report serious distress and a sometimes paradoxical discrepancy in subjective and objective perception of symptoms. Less often, patients with oral malodor are primarily seen by general practitioners and specialists like gastroenterologists or ear, nose and throat (ENT) doctors. Correct characterization of the underlying disease and an adequate diagnosis are made most successfully through interdisciplinary cooperation. CASE REPORT The case of a 43-year-old female patient is reported who presented with persistent oral malodor for > 1 year in the authors' outpatient department. Extensive diagnostic tests performed by various doctors in the past had not led to an adequate diagnosis and treatment. Clinical and laboratory examination in the authors' hospital showed normal findings apart from suspicion of chronic tonsillitis, confirmed by an ENT specialist. Therefore, tonsillectomy was performed. Histopathology revealed chronic tonsillitis with tonsillar actinomycosis but no other disease. 6 months after tonsillectomy the patient presented asymptomatic and comfortable. Oral malodor was no longer detectable. CONCLUSION Oral malodor has a broad differential diagnosis including chronic tonsillitis caused by Actinomyces species and concomitant anaerobic bacteria able to produce volatile sulphur compounds and other putrefactive molecules. Therapeutic gold standard in symptomatic disease is tonsillectomy, lacking comparative studies on the success rates of conservative antibiotic therapy, e.g., with aminopenicillins plus beta-lactamase inhibitor for several weeks or months. This case presentation illustrates that anticipated internal disease with an agonizing and prolonged cause of disease could be solved by tonsillectomy.

Abstract
OBJECTIVE To evaluate the incidence of unexpected histologic findings in routine tonsillectomy and adenoidectomy specimens. METHODS A retrospective medical record review was performed at a tertiary care children's hospital. The pathology records of 2062 children who underwent tonsil or adenoid surgery were analyzed and the final histologic diagnosis was recorded. RESULTS Four unexpected histologic findings were found on routine tonsil and adenoid specimens. None were clinically significant. A review of the literature shows a very low rate (0.015%) of unexpected clinically significant diagnoses in pediatric adenotonsillectomy specimens. CONCLUSIONS Given rarity of unexpected clinically significant diagnoses in pediatric adenotonsillectomy specimens, the cost and effort of analyzing each specimen histologically is difficult to justify.

Abstract
Actinomycosis is a slowly progressive infection that can occur anywhere in the body. Three distinct clinical entities are described: cervico-facial, abdomino-pelvic and thoracopulmonary. Actinomyces are anaerobic, gram positive, non-acid-fast, branched filamentous bacteria that form part of the normal oral, colonic and vaginal flora of humans. The cervico-facial form of the disease is commonest and results from direct invasion of commensal oral actinomyces into local tissues. The most frequently isolated species is A. israelii. We describe a case where Actinomycosis caused massive unilateral hypertrophy of the tonsil, mimicking neoplasia. This is an unusual presentation of Actinomycosis.

Abstract
OBJECTIVES The objective of the study was to establish the incidence of Actinomycosis in the tonsils of children undergoing tonsillectomy or adenotonsillectomy, and to evaluate its role in clinical tonsillar disease. METHODS This was a prospective controlled study done at the Red Cross Children's Hospital in Cape Town, South Africa over an 8-month period and included all children undergoing tonsillectomy or adenotonsillectomy. All resected tonsils were examined for the presence of Actinomycosis and any signs of significant cryptitis or active tonsillitis. A comparison was made in the incidence of Actinomycosis in children with obstructive sleep apnoea, recurrent tonsillitis or obstructive sleep apnoea and recurrent tonsillitis. The data was further analysed to determine the statistical significance of the association between Actinomycosis of the tonsils and age, sex and histopathological and clinical diagnosis. RESULTS A total of 344 tonsils were analysed on 172 patients. We found 20 patients (11.6%) with Actinomycosis in the tonsils. The mean age of patients with Actinomycosis was 7.25 years and without Actinomycosis was 5.4 years (p=0.002). Most specimens (16) had no evidence of tissue reaction to Actinomyces, and their presence was found to be due to colonisation of the tonsils only. Actinomycosis was present in 11% of patients with obstructive sleep apnoea, 11% of patients with recurrent tonsillitis and in 9% with obstructive sleep apnoea and recurrent tonsillitis. The difference in incidence of Actinomycosis between these three groups (p=0.94), and between the recurrent tonsillitis group alone compared to the obstructive group (p=0.83), was not statistically significant. There was therefore no statistical significance found between Actinomyces and OSA+/- recurrent tonsillitis. CONCLUSIONS There was no correlation found between the presence of tonsillar Actinomycosis and recurrent tonsillitis and/or obstructive tonsillar hypertrophy. Histopathologic findings showed no evidence of tissue reaction to Actinomyces and its presence was found to be due to colonisation of the tonsils only. The series did however show a statistically significant correlation between Actinomycosis colonisation and age with Actinomycosis being more common in older children, especially those over 5 years of age.

Abstract
INTRODUCTION Oral ulceration has many causes and is a common presenting symptom in otolaryngology. CASE REPORT This article presents an unusual case of dual pathology oral ulceration in an elderly patient. Oral malignancy was initially suspected, but the history, examination and investigation showed that the oral ulceration was caused by actinomycosis infection and by nicorandil use. DISCUSSION Cervicofacial acinomycosis is a rare, suppurative bacterial disease in which abscesses can form in the tissues and break through the skin, creating pus-discharging lesions. Nicorandil is a potassium channel blocker used in the treatment of ischaemic heart disease. It has been recently recognised as a cause of persistent ulcerative stomatitis. CONCLUSION This case highlights the importance of a high index of suspicion for unusual and reversible causes of oral ulceration, and of dual pathology as a cause. Such vigilance enables early recognition and treatment of potentially reversible conditions.

Abstract
OBJECTIVE To determine the prevalence of tonsillar actinomycetes colonization in patients with and without recurrent tonsillitis and to study the association of this condition with recurrent tonsillitis and tonsillar hypertrophy. STUDY DESIGN AND SETTING A retrospective study of 834 patients who had undergone tonsillectomy for recurrent tonsillitis (group A) and for sleep-disordered breathing without a history of recurrent tonsillitis (group B). RESULTS The prevalence of tonsillar actinomycetes colonization was higher in patients who had undergone tonsillectomy for sleep-disordered breathing (44.1 per cent) than in patients who had undergone tonsillectomy for recurrent tonsillitis (33.3 per cent). The prevalence did not differ by sex or age of patient, although the occurrence rate was higher in the adult compared with the paediatric population. There was no statistically significant difference between the mean size of the tonsils removed in the two groups, and actinomycetes colonization did not affect tonsil size. Histopathological analysis of resected tonsils did not show active tissue infection. CONCLUSION The presence of actinomyces does not indicate active disease. We are of the opinion that, although actinomyces colonization is more prevalent in patients with sleep-disordered breathing, it does not contribute to tonsillar hypertrophy nor to recurrent tonsillitis.

Abstract
We report a case of unusual presentation of actinomycosis in the tonsil causing massive unilateral enlargement in a 78-year-old female. To our knowledge, only three cases of actinomycosis causing unilateral tonsillar enlargement have been published previously. Since this anaerobic organism is difficult to culture, the diagnosis is made by observing its associated sulfur granules in the biopsy specimen. In the present case, treatment consisting of tonsillectomy and antibiotic therapy (penicillin) for several days produced a good prognosis.

Abstract
Palatine and nasopharyngeal tonsils are nonencapsulated nodular masses of lymphoid tissue of the respiratory and digestive tract epithelium. Study design Retrospective clinical study based on the revision of medical records of patients who underwent tonsillectomy and adenoidectomy at Hospital das Clínicas, Medical School, Marília in the period between January 2001 and May 2003. Aim Analysis of patients' profile and main pathological changes in 250 patients with palatine and nasopharyngeal tonsil hypertrophy, recurrent infections or both. Material and Method Histological review of 250 patients who underwent tonsillectomy and adenoidectomy among adults and children. Results Out of 250 subjects, 117 (46.8%) were female and 133 (53.2%) were male patients. Mean age was 7.3 years, ranging from 2 to 34 years. Main surgical indication was concomitant presence of recurrent infections and hypertrophy of nasopharyngeal and palatine tonsils. Among these patients, 160 (64%) were classified as grades III to IV hypertrophy. Lymphatic or follicular lymphatic hyperplasia was observed in 205 patients (82%); focal inflammation was verified in 45 (18%) subjects. Among those, 2 patients presented squamous cell cysts, 2 had Actinomyces sp colonies and 1 cat scratch disease. Discussion: The results presented in this study suggested a possible correlation between recurrent tonsillitis and palatine tonsil hypertrophy. Conclusion Routine histological study of tonsillectomy and adenoidectomy specimens has a low cost-benefit rate, although, due to legal and ethical issues, physicians may request this type of examination.

Abstract
As tonsilas palatinas e faríngeas são agregados encapsulados incompletos de nódulos linfóides em contato direto com o epitélio de revestimento do trato aerodigestivo. TIPO DE ESTUDO: Estudo retrospectivo baseado na revisão de prontuários dos pacientes submetidos a adenotonsilectomias no Hospital de Clínicas da Faculdade de Medicina de Marília durante o período de janeiro de 2001 a maio de 2003. OBJETIVO: Relatar o perfil dos pacientes e as principais alterações histopatológicas em 250 pacientes com hipertrofia de tonsilas palatinas e faríngea, infecções de repetição ou ambos. MATERIAL E MÉTODOS: Análise histopatológica de 250 pacientes submetidos a adenotonsilectomia ou tonsilectomia entre adultos e crianças. RESULTADOS: Dos 250 pacientes, 117 (46,8%) são do sexo feminino e 133 (53,2%) masculino. A idade média foi de 7,3 anos e variou de 2 a 34 anos. A principal indicação cirúrgica foi a concomitância de infecções de repetição e hipertrofia de tonsilas palatinas e faríngea, sendo que em 160 (64%) foram classificadas em 3+/4+. Em 205 (82%) pacientes foi encontrada hiperplasia linfóide ou linfóide folicular. 45 (18%) também apresentaram inflamação aguda supurativa focal. Dentre estes, 2 pacientes tiveram cistos de inclusão epidermóide, outros 2 com colônias de Actinomyces sp e 1 paciente com lesão compatível com Doença da Arranhadura de Gato. DISCUSSÃO: Os dados apresentados neste trabalho nos mostram uma possível relação das tonsilites de repetição com as hipertrofias tonsilas palatinas e faríngea. CONCLUSÃO: O exame anatomopatológico de rotina das tonsilectomias apresenta uma relação custo/benefício negativa, no entanto, por problemas de ordem legal, ético, fica o médico sujeito à solicitação desse exame.
