RESUMO ABSTRACTNeoplasias de cabeça e pescoço; Prevalência; Criança; Adolescente.Head and neck neoplasms; Prevalence; Child; Adolescent. Objecti ve: To verify the prevalence of malignant tumors of the head and neck region in infant and juvenile pati ents registered at the Cancer Hospital of Pernambuco, Recife, PE, Brazil. Method: This study was a retrospecti ve and cross-secti onal investi gati on in which 126 pati ent records were reviewed between 1995 and 2000. Informati on on the variables gender, age group, primary anatomic localizati on and histological type was recorded and transcribed to a specifi c chart. The data were analyzed using the Stati sti cal Package for Social Sciences (SPSS) soft ware, version 13.0. Results: 23 cases (18.3%) were malignant tumors aff ecti ng the head and neck region of children and adolescents. The age range was between 2 and 17 years (mean age 13 years), and most pati ents were aged 13 to 18 years (65.2%). There was a predominance of male pati ents (65.2%), with a male-tofemale rati o of 1.8:1. The nasopharynx was the most aff ected anatomic region (21.7%), followed by the paroti d gland and oral cavity (17.4%). The most frequent histological types were those derived from the epithelial lineage (48%), among which the undiff erenti ated carcinoma (13%). Among the tumors derived from the mesenchymal ti ssue, the most frequent were rhabdomyosarcoma (30%) and lymphoma (17%). DESCRITORES KEYWORDS Conclusion:Research on infant and juvenile cancer in Brazil address the populati on basis and the mortality in a general manner. Data on the prevalence of malignant tumors of the head and neck region in children and adolescents are sti ll scarce. Further studies on this area should be encouraged because they are important in the elaborati on and planning of nati onal or regional public policies and health programs.

The aim of this paper is to report a case of odontogenic myxoma that affected the right maxilla and maxillary sinus. We have also reviewed the literature in regards of the clinical, radiographic, histological and treatment aspects of this pathology. Odontogenic myxomas of the maxillofacial region are benign lesions, without preference for gender, race or location, with extremely varied clinical and radiographic characteristics, thus increasing the number oral and maxillofacial region tumors with which we can make the differential diagnosis.

A survey was carried out on all cases of pulmonary and extrapulmonary tuberculosis reported in the Latium region of Italy during 1986, in order to characterize them from bacteriological and epidemiological points of view. A total of 497 TB notifications were investigated; reliable medical records were traced and consulted for 458 of these. Seventy-six percent of cases was classified as respiratory tb, 21.8% non-respiratory tb and 2% both. Ninety-two percent of all cases had been hospitalized for long periods (mean: 69 days/median: 63 days for cases of respiratory TB and mean: 40/median 29 days for non-respiratory patients). Contrary to the definition of a reportable case in Italy, evidence of Mycobacteria on direct or cultural examination was present in only half of all reported patients. Twenty-seven percent of respiratory cases and 33.3% of non-respiratory had a previous diagnosis of TB mentioned on the clinical record. High daily alcohol intake is reported more frequently among TB patients with respect to the general population, while drug abusers, immigrants and HIV seropositives represent a very low proportion. Delays in notification have been observed and current notification system is evaluated.

A Hiperplasia Fibrosa inflamatória (HFI) conhecida como Epúlide Fissurada é considerada uma lesão proliferativa frequente na cavidade bucal, é geralmente assintomática, resultante de uma reação hiperplásica do tecido conjuntivo. Tem como tratamento de eleição a exérese cirúrgica que pode ser empreendida por bisturi frio (convencional), cirurgia a laser, eletrocirurgia e crioterapia. A metodologia utilizada foi uma busca ativa em base de dados eletrônicos no Pubmed/ Medline, Scielo, Portal Periódicos CAPES e LILACS em artigos científicos publicados nos últimos 10 anos na língua inglesa e língua portuguesa, utilizando os descritores: Hyperplasia, Denture, Complete, Pathology, Oral, Surgery, Oral. Após os critérios de elegibilidade foram selecionados os artigos e relatado o caso clínico para discussão das condutas de diagnóstico e tratamento. O objetivo deste trabalho busca relatar um caso clínico de HFI como também realizar uma breve comparação dos métodos de tratamento que podem ser empreendidos no tratamento das HFI. Relato de Caso: Paciente do gênero feminino, 73 anos de idade, com queixa principal de crescimento tecidual em região gengival e incômodo ao uso de prótese total, foi tratada por eletrocirurgia de forma satisfatória. Conclusão: A eletrocirurgia é o método mais acessível e eficaz no tratamento cirúrgico da Epúlide Fissurada.

In 2015, in Northeast Brazil, cases of microcephaly associated with the outbreak of zika virus in South America were identified. This virus is transmitted by the biological vector Aedes aegypti, which also transmits dengue, yellow fever, and chikungunya viruses. The congenital Zika syndrome affected newborns with head circumference smaller than 32 cm, compromising their central nervous system. Besides ocular lesions, hyperexcitability, and hypertonia, newborns also showed intracranial calcifications in imaging exams. If children with congenital Zika syndrome suffer maxillofacial alterations during embryonic development, they could have delayed tooth eruption and malformations. This study aims to perform an integrative review of the current literature about the health conditions of children with congenital Zika virus infection and the possible alterations of their oral cavity. This integrative literature review was performed by searching scientific articles in the PubMed, SciELO, and MEDLINE electronic databases with the descriptors “Zika Virus Infection”, “Zika Virus”, and “Microcephaly”, which deal with clinical case reports and were indexed between 2016 and 2021. About 26 articles published entirely in English were analyzed after meeting the eligibility criteria. The studies contributed to better treatment conducts by showing the neurological, functional, and oral alterations in children with congenital Zika syndrome, including periodontal diseases, malocclusions, dental caries, bruxism, micrognathia, ankyloglossia, short labial frenum, dental trauma, and dysphagia.

A supernumerary tooth is one that is additional. The diagnosis is usually made by clinical exam and routine radiographs, and the majority of such teeth are impacted and asymptomatic, without affect others teeth. The supernumerary teeth, can occur included or impacted. An early diagnosis is important in order to implement a suitable plan of treatment and prevent such complications. Ectopic inclusions occur at about 1% of the general population and might be present at many diverse localizations. In this article the authors review the literature around the ectopic inclusions and report a case of an intranasal ectopic supernumerary inclusion. The prophylactic surgical removal of the supernumerary teeth is generally the treatment of choice.
