RESUMO

OBJECTIVE: to report the first case series of Brazilian children diagnosed with Kleefstra syndrome, present a possible phenotype expansion to the syndrome and to raise physicians' awareness for this rare disease. RESULTS: seven patients with confirmed KS were evaluated, including 5 males and 2 females. Abnormal prenatal findings were observed in 4 patients. Most patients were born at term, with normal birth measurements. All patients had neurodevelopmental delay and 6 evolved with intellectual disability. Hearing loss was present in 57.1% of patients and 28.7% had congenital heart disease. In males, cryptorchidism was present in 75%. Despite the facial dysmorphisms, only 2 out of 7 patients had a pre-test clinical suspicion of KS. One specific patient presented bilateral agenesis of the semicircular canals, a very rare ear manifestation in Kleefstra syndrome, representing a possible phenotype expansion of the syndrome. CONCLUSION: this report aims to promote awareness among physicians evaluating patients in a context of neurodevelopmental delay or congenital malformations, especially congenital heart defects. We also highlight a possible phenotype expansion of the syndrome, with a case of semicircular anomaly, not reported in this syndrome so far.

RESUMO

INTRODUCTION: Little is known about rates of suicidal ideation and behavior among youth with cleft lip and/or palate (CLP) and other craniofacial conditions. METHODS: Records of patients ages 6 and older who were administered the Columbia-Suicide Severity Rating Scale (C-SSRS) Lifetime Version during routine multidisciplinary cleft or craniofacial team visits between 2019 and 2023 were examined. Demographics information, C-SSRS data, and diagnoses were assessed with statistics including t tests, the Fisher exact test, and odds ratios. RESULTS: A total of 1140 C-SSRS questionnaires across 602 (433 CLP and 169 craniofacial) patients with an average age of 11.2±3.7 years were included. Eighty-four (13.6%) patients endorsed lifetime suicidal ideation, 9 (1.5%) had at least one instance of suicidal behavior, 30 (5.0%) endorsed nonsuicidal self-injury, and 2 (0.3%) engaged in self-injurious behavior. Compared with CLP, those with other craniofacial conditions had similar odds of endorsing suicidal ideation and behavior ( P ≥0.05). Compared with those with isolated cleft palates, CLP had greater odds of endorsing suicidal ideation and behavior, though those differences were not significant ( P ≥0.05). Incidence of suicidality was unchanged before, during, and after the COVID-19 pandemic ( P ≥0.05). Dividing patients by sex or insurance type revealed no difference in suicidality ( P ≥0.05). CONCLUSION: Patients with CLP and craniofacial conditions have a high incidence of suicidal ideation and behavior, though levels are similar between these groups. Suicidality in these patients was not negatively impacted by the COVID-19 pandemic. Early identification of safety risks and psychosocial challenges through regular screening can facilitate connection with appropriate clinical interventions.

RESUMO

Diprosopus is a congenital anomaly in which partial or complete duplication of craniofacial structures occurs. Because it is rare, the mortality rate is high, and information concerning this anomaly is scarce. This study describes a case of human diprosopus in a 9-year-old male individual, who has severe complications associated with the central nervous, cardiovascular, respiratory, and digestive systems. Since birth, he has been monitored in a specialized hospital environment, where he has undergone several surgeries and multidisciplinary treatments. Regarding the craniofacial aspects, he had agenesis of the corpus callosum, floor of the nasal cavity, and floor of the anterior cranial fossa, in addition to the presence of bone dysplasia, ocular hypertelorism and cleft palate with nasal and oral teratoma. Regarding dental characteristics, the patient has duplication of the maxilla, mandible, tongue, and some teeth. After complementary imaging exams, several supernumerary teeth were found, with some being impacted and in complex regions, with an indication for extraction due to the risks of impaction, irruptive deviation, root resorption, and associated cystic or tumoral lesions. Because of the numerous complications, knowledge, and preparation of the entire team is necessary for the correct management of the case.

RESUMO

Objetivo: avaliar a prevalência de anomalias dentárias (AD) e outros achados orais em radiografias panorâmicas de pacientes com fissuras labiopalatais (FLP) nascidos no Nordeste brasileiro. Métodos: a amostra foi composta por 69 pacientes com fissuras labiopalatais unilateral (FLPu) (n = 51) e bilateral (FLPb) (n = 18), não sindrômicos, de ambos os sexos, idade de 6 a 17 anos, nascidos no Nordeste brasileiro. Foram analisados prontuários e radiografias panorâmicas de pacientes atendidos de janeiro/2020 a julho/2022. Os dados categóricos foram expressos em forma de frequência absoluta e percentual e comparados por teste exato de Fisher ou qui-quadrado de Pearson (SPSS, p < 0,05). Resultados: entre os achados orais, destacaram-se as anomalias de número e as ausências dentárias por trauma, cárie ou doença periodontal. As AD foram identificadas em 34 pacientes (49,3%). As anomalias de número apresentaram maior prevalência, com diferença estatística significativa para pacientes FLPb do sexo masculino (p = 0,047). A agenesia foi a AD mais frequente (n = 24; 34,8%). As ausências dentárias por trauma, cárie ou doença periodontal foram observadas em 44 pacientes (n = 63,8%), com uma diferença estatística significativa entre os grupos FLPu e FLPb (p = 0,018). Conclusões: as AD e as ausências dentárias por trauma, cárie ou doença periodontal apresentaram uma alta prevalência entre pacientes brasileiros com FLP e devem ser consideradas durante o planejamento ortodôntico-cirúrgico desses indivíduos.

Aim: this study aimed to assess the prevalence of dental anomalies (DA) and other oral findings in panoramic radiographs of patients with cleft lip and palate (CLP) born in the Northeast region of Brazil. Methods: the sample consisted of 69 patients with unilateral cleft lip and palate (UCLP) (n = 51) and bilateral cleft lip and palate (BCLP) (n = 18), non-syndromic, of both genders, aged 6 to 17 years, born in the Brazilian Northeast. Patient records and panoramic radiographs from those treated between January 2020 and July 2022 were analyzed. Categorical data were expressed as absolute frequency and percentage and compared using Fisher's exact test or Pearson's chi-square test (SPSS, p < 0.05). Results: among oral findings, anomalies in number and tooth absences due to trauma, caries, or periodontal disease stood out. DAs were identified in 34 patients (49.3%). Anomalies in number showed higher prevalence, with a statistically significant difference for male BCLP patients (p = 0.047). Agenesis was the most frequent DA (n = 24; 34.8%). Tooth absences due to trauma, caries, or periodontal disease were observed in 44 patients (63.8%), with a statistically significant difference between the UCLP and BCLP groups (p = 0.018). Conclusions: DAs and tooth absences due to trauma, caries, or periodontal disease showed a high prevalence among Brazilian patients with CLP and should be considered during the orthodontic-surgical planning for these individuals.

RESUMO

Los trastornos del desarrollo son aquellos padecimientos que se manifiestan por defectos en la embriogénesis de la región afectada. La cara del ser humano comienza su formación alrededor de la cuarta semana de vida intrauterina y se manifiesta gracias a la fusión de cinco prominencias: dos pares conocidas como maxilar y mandibular, y una impar conocida como frontonasal. Cuando esta fusión no se lleva a cabo de una forma óptima, aparecen numerosas alteraciones del desarrollo como el labio y paladar hendido, y la displasia frontonasal. La displasia frontonasal produce frecuentemente afecciones oculares, nasales y orales. Dentro de las manifestaciones orales destacan una forma atípica de hendidura labial o palatina, afecciones dentales y alteraciones en el crecimiento de la cara. Dada la gran relación que este padecimiento tiene con la cavidad oral resulta importante que el odontólogo conozca la etiología y las características clínicas de este trastorno (AU)

Developmental disorders are those conditions that are manifested by defects in the embryogenesis of the affected region. The human face begins its formation around the fourth week of intrauterine life and is manifested thanks to the fusion of five prominences: two pairs known as maxillary and mandibular and odd one known as frontonasal. When this fusion is not carried out in an optimal way, numerous developmental alterations appear, such as cleft lip and palate and frontonasal dysplasia. Frontonasal dysplasia frequently produces ocular, nasal and oral affections. Among the oral manifestations, and atypical form of clef lip and/or palate, dental affections and alterations in the growth of the face stand out. Given the great relationship that this condition has with the oral cavity, it is important for the dentist to know the etiology and clinical characteristics of this disorder (AU)

RESUMO

BACKGROUND: Traboulsi syndrome is a rare disease clinically characterized by facial dysmorphism, abnormal spontaneous filtering blebs, ectopia lentis (EL) and multiple anterior segment abnormalities. MATERIAL AND METHODS: An 18-year-old female was referred to the Emergency Service of Hospital São Geraldo (HSG) claiming decreased right eye (RE) visual acuity associated with ocular pain that was noticed approximately 2 months earlier. She underwent a complete ophthalmic and physical examination including hands, ankle, wrist and chest X-ray, abdominal ultrasound, echocardiogram and genetic analysis (whole-exome sequencing). RESULTS: The ophthalmic examination revealed a high myopia with spherical equivalent of - 9.50 D and best corrected visual acuity (BCVA) of 20/60 in RE and - 9.25 D with BCVA of 20/30 in the left eye (LE). Slit-lamp examination showed normal conjunctiva in both eyes (BE) and a superior-temporal cystic lesion in RE and nasal in LE; the flat anterior chamber in BE with the transparent crystalline lens touches the central corneal endothelium in the RE. Fundoscopy suggested glaucoma as the cup/disc ratio was 0.7, although the intraocular pressure (IOP) was 10 mmHg in BE without medication. Validation of data from whole exome demonstrated a novel splicing homozygous pathogenic variant (PV) (c.1765-1G>A) of the ASPH gene as well as a heterozygous variant of unknown significance (VUS) of the FBN1 gene (c.6832C>T). CONCLUSION: We here report a novel splice-affecting homozygous pathogenic variant in the ASPH gene that was detected in a Brazilian patient with clinical features of Traboulsi syndrome.

RESUMO

Introduction: sickle Cell Disease (SCD) is an inherited, hematological, chronic disease that mostly affects racial/ethnic groups. The dental literature discusses SCD's oral symptoms, such as malocclusion and craniofacial abnormalities, without considering the significance of a racial/ethnic perspective. Objective: this article critically reviewed the findings of the studies based on a racial/ethnic standpoint and SCD landmarks. Sources of data: primary and secondary searches selected 146 studies from four scientific literature databases. Two reviewers independently extracted data from eleven included studies. Synthesis of data: most studies used lateral cephalometry and reported craniofacial abnormalities and malocclusions, such as maxillary protrusion, class II skeletal patterns, vertical facial growth patterns, convex facial profile, mandibular retrusion, and the posterior rotation of the jaw. However, there is no mention of racial or ethnic cephalometric patterns to support these findings in the studied populations. In addition, a misunderstanding occurs when overlooking the different periods of growth or ages within and between the studied groups. Furthermore, there is no mention of previous orthodontic treatment. By contrast, there is a lack of information about the medically compromised health status of people with SCD, such as the life period of SCD's diagnosis; the number and timing of blood transfusions; the medical history of hospitalizations, vaso-occlusive crises, or hydroxyurea use. Conclusion: racial and ethnic concerns for the diagnosis of malocclusions and craniofacial anomalies, as well as SCD landmarks, are underappreciated in the examined dental literature. Discarding them also demonstrates institutional racism.

Introdução: a doença falciforme é uma doença hematológica, hereditária, crônica, que afeta principalmente, a população negra, em escala global. Na literatura odontológica, os achados craniofaciais e oclusais relacionados à doença falciforme são discordantes, mas, em comum, desconsideram a perspectiva racial. Objetivo: este artigo revisou criticamente a literatura odontológica e discutiu os achados encontrados na perspectiva racial/étnica. Fonte dos dados: estudos primários e secundários selecionaram 146 ocorrências de quatro bases de dados da literatura científica. Dois revisores extraíram independentemente os dados dos onze estudos incluídos. Síntese dos dados: com base na cefalometria lateral, a maioria dos estudos concluiu que as anormalidades craniofaciais e maloclusões, como protrusão maxilar, padrão esquelético de classe II, padrão de crescimento facial vertical, perfil facial convexo, retrusão mandibular e rotação posterior da mandíbula foram os mais comuns achados para pessoas com doença falciforme. No entanto, ao considerar a perspectiva étnico-racial, não há menção na maioria dos estudos de ajustes dos padrões cefalométricos específicos para as populações racializadas, nem tampouco são consideradas características do grupo populacional e da doença falciforme em si, como sua severidade, o momento de vida em que o diagnóstico ocorreu, número e período de hemotransfusões, internações, crises vaso-oclusivas ou uso de hidroxiureia. Além disso, a ampla faixa etária em diferentes períodos de crescimento ósseo e a ausência de informação sobre tratamento ortodôntico prévio foram observadas. Conclusão: há omissão sobre considerações étnico-raciais para relatar anormalidades craniofaciais e maloclusões sobre doença falciforme na literatura odontológica revisada. Isto pode ser uma expressão do racismo.

RESUMO

Oculodentodigital dysplasia (ODDD; MIM #164200), a rare genetic disorder characterized by abnormal craniofacial, dental, ocular, and digital features, is caused by mutations in GJA1 (gap junction alpha-1) gene and inherited in an autosomal dominant pattern. However, an autosomal recessive pattern is also reported. Here we described 2 families with members affected by ODDD. In the first family, the c.752G>C (p.S251T) and c.848C>T (p.P283L) heterozygous missense mutations and the c.825C>T (p.T275T) silent mutation were identified in the proband, which showed mild ODDD phenotypes, and in his mother, which displayed hemolytic anemia and thrombocytopenia. In the second family, the patients displayed typical features of ODDD, and Sanger sequencing identified a novel homozygous c.604C>T (p.R202C) missense mutation, whereas the parents carried the mutation. Together, these findings suggest that homozygous mutation in GJA1 induces a more severe ODDD phenotype, though interfamilial phenotype variability was observed, whereas compound heterozygous mutations in GJA1 cause a mild phenotype.
