Orthodontic treatment and referral patterns: A survey of pediatric dentists,general practitioners,and orthodontists

Objective

This study aims to assess the orthodontic diagnostic skills, referral patterns, and the perceptions of orthodontic benefits of pediatric and general dentists in comparison with orthodontists.

Materials and methods

Two online surveys were e-mailed to pediatric dentists, general dentistry practitioners, and orthodontists registered as members of the Saudi Dental Society and the Saudi Orthodontic Society. The surveys included questions about the type of orthodontic treatment provided, referral trends, and timing; presumed benefits associated with successful orthodontic treatment; and diagnosis and treatment plans of seven cases representing different malocclusions.

Results

In total, 25 orthodontists, 18 pediatric dentists, and 14 general practitioners completed the survey. Only 38.8% of pediatric dentists and 7.1% of general practitioners reported that they practiced orthodontics clinically. The perceptions of the three groups toward the benefits of orthodontic treatment were comparable in the psychosocial areas. However, the orthodontists perceived significantly lesser effects of orthodontic treatment on the amelioration of temporomandibular disorder (TMD) symptoms. Pediatric dentists tended to rate the need and urgency of treatment higher, while general practitioners tended to rate the need of treatment lower. The selected treatment plans for three early malocclusion cases showed the greatest discrepancies between the orthodontists and the other two groups.

Conclusions

The orthodontists consistently and significantly downplayed the perceived benefit of orthodontic treatment to reduce TMD symptoms. Also, while there was a similarity in the diagnosis, there were notable differences in the proposed treatment approaches, perceived treatment need, and timing of intervention between the three groups of practitioners.     

Optimizing the management of patients with spinal myeloma disease

Myeloma is one of the most common malignancies that results in osteolytic lesions of the spine. Complications, including pathological fractures of the vertebrae and spinal cord compression, may cause severe pain, deformity and neurological sequelae. They may also have significant consequences for quality of life and prognosis for patients. For patients with known or newly diagnosed myeloma presenting with persistent back or radicular pain/weakness, early diagnosis of spinal myeloma disease is therefore essential to treat and prevent further deterioration. Magnetic resonance imaging is the initial imaging modality of choice for the evaluation of spinal disease. Treatment of the underlying malignancy with systemic chemotherapy together with supportive bisphosphonate treatment reduces further vertebral damage. Additional interventions such as cement augmentation, radiotherapy, or surgery are often necessary to prevent, treat and control spinal complications. However, optimal management is dependent on the individual nature of the spinal involvement and requires careful assessment and appropriate intervention throughout. This article reviews the treatment and management options for spinal myeloma disease and highlights the value of defined pathways to enable the proper management of patients affected by it.     

Birth prevalence of non-syndromic orofacial clefts in Saudi Arabia and the effects of parental consanguinity

Objectives:

To describe the characteristics and prevalence of non-syndromic orofacial clefting (NSOFC) and assess the effects of parental consanguinity on NSOFC phenotypes in the 3 main cities of Saudi Arabia.

Methods:

All infants (114,035) born at 3 referral centers in Riyadh, and 6 hospitals in Jeddah and Madinah between January 2010 and December 2011 were screened. The NSOFC cases (n=133) were identified and data was collected through clinical examination and records, and information on consanguinity through parent interviews. The diagnosis was confirmed by reviewing medical records and contacting the infants’ pediatricians. Control infants (n=233) matched for gender and born in the same hospitals during the same period, were selected.

Results:

The prevalence of NSOFC was 1.07/1000 births in Riyadh, and 1.17/1000 births overall; cleft lip (CL) was 0.47/1000 births, cleft lip and palate (CLP) was 0.42/1000 births, and cleft palate (CP) was 0.28/1000 births. Cleft palate was significantly associated with consanguinity (p=0.047, odds ratio: 2.5, 95% confidence interval: 1 to 6.46), particularly for first cousin marriages.

Conclusion:

The birth prevalence of NSOFC in Riyadh alone, and in the 3 main cities of Saudi Arabia were marginally lower than the mean global prevalence. While birth prevalence for CLP was comparable to global figures, the CL:CLP ratio was high, and only CP was significantly associated with consanguinity.Non-syndromic orofacial clefting (NSOFC), including isolated cleft lip (CL), cleft lip and palate (CLP), and isolated cleft palate (CP), is the most common craniofacial defect worldwide with an estimated mean global prevalence of 1.25/1000 live births.1 However, the prevalence of NSOFC varies geographically and across different ethnic groups.2 Although the ethnicity of the Middle East is considered Caucasian,3,4 geographically it is located between 3 continents (Asia, Africa, and Europe), which makes it unique and, in reality, a mixture of 3 ethnicities. A small number of studies have measured the prevalence of NSOFC in Saudi Arabia and neighboring countries with the reported prevalence ranging from 0.3 to 2.19/1000 births,5-9 and a mean value for all studies of 1.25/1000 births.10 In addition, consanguineous relationships have been suggested to increase the prevalence of congenital anomalies.11 These were also reported to be associated with NSOFC in a meta-analysis carried out on 16 studies that assessed the relationship between NSOFC and paternal consanguinity.12 Saudi Arabia, one of the largest countries in the Middle East, has a high rate of consanguineous marriage that varies between regions.13 Riyadh, which is the capital city of Saudi Arabia with a population of approximately 7.5 million and birth prevalence of 38,000/year,14,15 has a consanguinity marriages prevalence of 60%.16 The aims of this study were to 1) describe the characteristics and prevalence of NSOFC (CL, CLP, and CP) in Riyadh (the capital city in the central region of Saudi Arabia), 2) describe the prevalence of NSOFC phenotypes, and 3) the relationship between these and consanguinity in Saudi Arabia.
