Oral and Maxillofacial Manifestations of Kallmann Syndrome: A Systematic Analysis of the Literature

AIMS

Kallmann syndrome (KS) is a rare genetic disorder characterized by congenital hypogonadotropic hypogonadism and varied clinical features. Despite its recognition, the oral and maxillofacial manifestations remain poorly understood. This study synthesized clinical aspects and management of KS-related oral and maxillofacial alterations.

METHODS

Searches were conducted in the PubMed, Web of Science, Scopus, Embase, and LILACS databases, supplemented by manual scrutiny and gray literature. Case series and/or case reports were included. The Joanna Briggs Institute tool was employed for critical appraisal of the studies.

RESULTS

A total of 46 studies comprising 108 cases were included. The mean age of individuals was 19.8 (±12.6) years, and there was a marked predominance of males (79.3%). Cleft lip/palate (32.7%) was the predominant oral condition, followed by high-arched palate (21.7%), and dental agenesis (19.8%). Oral treatment consisted of corrective surgery of the cleft lip and/or palate (n = 9), myoplasty (n = 1), and tooth extraction/orthodontic treatment (n = 1). Hyposmia/anosmia (71.3%) was the most frequently reported manifestation.

CONCLUSION

Early diagnosis and interdisciplinary collaboration are essential for addressing the complex nature of KS-related oral and maxillofacial alterations and improving patient outcomes. The scarcity of data on oral treatment underscores the need for additional research and clinical attention in this field.

Oral Problems in Brazilian Individuals with Rare Genetic Diseases That Affect Skeletal Development

The present study aimed to compare the prevalence of oral problems between individuals with rare genetic diseases that affect skeletal development and individuals without rare diseases. A cross-sectional study was conducted with 210 individuals between two and fifty-four years of age: 105 with rare genetic diseases (27 with mucopolysaccharidosis [MPS] and 78 with osteogenesis imperfecta [OI]) and 105 without rare diseases. The rare genetic disease group was recruited from hospital units that provide care for patients with MPS and OI in five states of Brazil, and the other group was recruited from the same location. The participants were examined with regards to malocclusion, dental anomalies, dental caries, and gingivitis. A questionnaire was administered addressing individual, sociodemographic, and behavioral characteristics as well as dental history. A descriptive analysis was performed, followed by unadjusted and adjusted binary logistic regression analyses. The mean age was 14.1 ± 12.2 years. Individuals with a rare disease were 12.9-fold more likely to have some type of oral problem (95% CI: 3.7-44.7) compared to the group without rare diseases. The prevalence of oral problems was higher among Brazilians with MPS and OI compared to normotypical individuals.

Contextual Variables with an Impact on the Educational Inclusion of Students with Rare Diseases

The context of a school may play a fundamental role in students' academic and personal progress. In this study, we focus on two contextual variables, the school type and school location or setting. The study used a questionnaire to assess teachers' knowledge and thoughts about rare diseases based on these variables, with the participation of 574 school teachers. To broaden the research perspective, another questionnaire was administered to members of 152 rare disease patient advocacy groups to ask about their participation in educational processes and analyse their results according to one of the contextual variables: the setting or location of each association. The results indicated statistically significant differences according to the variables examined, which were larger for the type of school variable. In short, numerous variables that influence the teaching and learning processes need to be considered in educational praxis; in this study, we looked at those of a contextual nature (for example, the geographic characteristics of schools and associations), and this is essential for increasingly heterogeneous educational locations that demand multidimensional approaches.
