Candida species biotypes in the oral cavity of infants and children with orofacial clefts under surgical rehabilitation.

Patients with orofacial clefts present various risk factors for oral infectious diseases, resulting from anatomical and physiological changes and those resulting from rehabilitating therapeutic interventions. The incidence of Candida species in groups of babies and children with orofacial clefts, during pre- and post-operative periods and until return to first consultation, and the profiles for antifungal sensitivity and virulence in vitro were investigated. Oral samples were collected at different times over the surgical procedures and post-surgical clinical consultation and seeded in chromogenic culture media CHROMagar Candida®. Candida biotypes were identified by accessing species-specific genomic DNA sequences by PCR techniques and electrophoretic procedures. Antifungal susceptibility testing was performed by the method of microdilution in broth using the antifungals amphotericin B (AP), nystatin (NYS) and fluconazole (FLC). SAP and PL exoenzyme activities were determined by classical microbiological methods. Some orofacial clefts occurred preferentially in male or female. Low incidence (39.1%) of oral colonization by Candida species (C. albicans, C. krusei, C. tropicalis and Candida spp.) was reported in patient admission to surgical ward, with no correlation to orofacial cleft types or surgical history. Significant reduction in frequencies of Candida and changes of species, over sampling periods, showed dynamic patterns of oral colonization: elimination, maintenance or neocolonization of the biotypes. These biotypes showed sensitivity to AP (100%), partial resistance to FLC (<10%) and variable MICs for NYS (0.125-4 µg/mL), in addition to strong exoenzyme activities, especially for SAP. Clinical and therapeutic conducts for surgical rehabilitation, anatomical and physiological characteristics of patients with orofacial clefts, and cultural behavior and regionalism of the patient population served could influence the frequencies and dynamics of oral colonization by Candida species. The data showed Candida biotypes resistant to FLC and sensitive (AP) or clinically compatible (NYS) to polyenes, especially C. albicans, in the oral cavity of patients predisposed to oral colonization and candidiases, contributing to clinical conducts in possible antifungal therapies. These biotypes were considered potentially virulent and able to partially modulate their virulence factors, especially SAP, under the conditions favored by host.

Cleft lip and palate: series of unusual clinical cases.

UNLABELLED: Cleft lip and/or palate (CL/P) represent the most common congenital anomalies of the face, corresponding to approximately 65% of all malformations of the craniofacial region. AIM: to describe unusual clinical cases of non-syndromic CL/P (CL/PNS), diagnosed in a reference service in Minas Gerais, Brazil, and correlate these alterations with possible risk factors. MATERIALS AND METHODS: we carried out a retrospective study, between the years of 1992 and the 1st half of 2009, from medical records. RESULTS: Among the 778 cases of CL/PNS diagnosed in the period of 17 years, 5 (0.64%) were unusual CL/PNS, and all patients were male. It was found that among the 5 patients, 2 had incomplete right cleft lip with incomplete cleft palate, 2 were affected by left incomplete cleft lip and incomplete cleft palate, and 1 had a cleft lip and palate associated with complete right cleft palate. Risk factors such as consanguinity, maternal smoking and alcohol consumption, medication usage during pregnancy, history of abortion and/or stillbirths and maternal diseases were not associated with unusual CL/PNS. CONCLUSIONS: This study described 5 unusual cases of CL/PNS in a Brazilian population; no associations with the risk factors analyzed were seen. It also confirmed the unusualness of the prevalence of such alterations.

Fissuras lábio-palatinas: série de casos clínicos incomuns / Cleft lip and palate: series of unusual clinical cases

Fissuras do lábio e/ou palato (FL/P) representam as anomalias congênitas mais comuns da face, correspondendo a aproximadamente 65 por cento de todas as malformações da região craniofacial. OBJETIVO: Descrever casos clínicos incomuns de FL/P não-sindrômicas (FL/PNS), diagnosticadas em um Serviço de referência em Minas Gerais, Brasil, e correlacionar tais alterações com possíveis fatores de risco. CASUÍSTICA E MÉTODOS: Realizou-se estudo retrospectivo, entre os anos de 1992 e 1º semestre de 2009, a partir dos prontuários clínicos. RESULTADOS: Entre 778 casos de FL/PNS diagnosticadas no período de 17 anos, 5 (0,64 por cento) foram de FL/PNS incomuns, sendo todos os pacientes do gênero masculino. Verificou-se que, dos 5 pacientes, 2 apresentaram fissura labial direita incompleta associada à fissura palatina incompleta; 2 eram afetados por fissura labial esquerda incompleta e fissura palatina incompleta e 1 com fissura lábio-palatina esquerda completa e fissura palatina direita completa. Fatores de risco como consanguinidade, tabagismo e etilismo materno, uso de medicamento na gestação, histórico de aborto e/ou natimorto e doenças maternas não foram associados às FL/ PNS incomuns CONCLUSÕES: Este estudo descreveu 5 casos raros de FL/PNS em uma população brasileira, não apresentando correlação com os fatores de risco analisados. Confirmou-se ainda a raridade na prevalência de tais alterações.

Técnicas cirúrgicas correntes para fissuras lábio-palatinas, em Minas Gerais, Brasil / Current surgical techniques for cleft lip-palate in Minas Gerais, Brazil

Fissuras do lábio e/ou palato (FL/P) representam as anomalias congênitas crânio-facial mais comuns. OBJETIVO: Avaliar as técnicas cirúrgicas correntes na reabilitação de FL/P em um Serviço de referência no Estado de Minas Gerais. Material e métodos: Realizou-se estudo retrospectivo, 2002 a 2007, avaliando 109 portadores de FL/P não sindrômicas que tiveram o tratamento concluído. As dimensões de análise (identificação pessoal, classificação das FL/P e tratamento cirúrgico realizado) foram obtidas a partir dos prontuários, sendo posteriormente construído banco de dados e as análises estatísticas realizadas pelo programa SPSS 13.0. Seguiu-se análise descritiva dos procedimentos cirúrgicos em função do tipo de FL/P encontrada. Resultados: Entre os 109 pacientes, 65,1 por cento foram do gênero masculino e 34,8 por cento do feminino. Verificou-se que 45 por cento dos pacientes apresentaram fissuras lábio-palatinas, 37,6 por cento fissuras labiais e 17,4 por cento fissuras palatinas. As técnicas correntes empregadas foram as de Millard e Spina para as queiloplastias, McComb para as rinoplastias e as de Veau e Van Langenbeeck para as palatoplastias. Conclusão: Este estudo é o primeiro a abordar reabilitação em FL/P em Minas Gerais. Nas FL/P unilaterais houve a associação das técnicas de McComb, Veau e Millard, respectivamente, para rinoplastia, palatoplastia e queiloplastia, em 76,9 por cento dos pacientes.

Cleft lip and palate (CL/P) are the most common congenital anomalies of the craniofacial region. AIM: to evaluate the surgical techniques used in CL/P treatment in a craniofacial deformities ward, in Minas Gerais. Materials and methods: In this retrospective study, carried out between 2002 and 2007, we studied 109 individuals with non-syndromic CL/P submitted to treatment. The aspects analyzed (personal identification, classification of CL/P and surgical treatment performed) were obtained from patient charts, and then we built a database and ran statistical analyses through the SPSS 13.0 software. Followed by descriptive analysis of the surgical procedures depending on the type of CL/P found. Results: Among the 109 patients, 65.1 percent were males and 34.8 percent females. We found that 45 percent of patients had cleft lip and palate, 37.6 percent cleft lip only and 17.4 percent cleft palate only. The surgical techniques employed were predominantly those from Millard and Spina for cheiloplasty, McComb for rhinoplasty and, Veau and Van Langenbeeck for palatoplasty. Conclusions: This study is the first to address treatment procedures for individuals with CL/P in the state of Minas Gerais. For unilateral CL/P we predominantly used the association of McComb, Veau and Millard techniques, respectively, for rhinoplasty, palatoplasty and cheiloplasty, in 76.9 percent of the patients.
