The clinical and radiological features and prevalence of Neuro-Behçet's Disease: A retrospective cohort multicenter study in Saudi Arabia

BACKGROUND

Neuro-Behçet's disease (NBD) is defined as primary neurological involvement in patients with systemic symptoms of BD. The variety of clinical presentations seen in NBD and the long list of similar conditions make diagnosis challenging. This retrospective study aimed to estimate the prevalence and describe neurological involvement in patients with Behçet's disease who presented to King Abdulaziz Medical Cities in Jeddah and Riyadh, Saudi Arabia.

METHODS

This was a retrospective, cohort study which utilized a non-probability consecutive sampling technique to include all patients diagnosed with NBD patients. All patients with BD (215) were screened for neurological symptoms. Thirty-five patients were found to be diagnosed with NBD. Outcomes were estimated using the modified Rankin scale (mRS).

RESULTS

In our cohort, one in six patients with BD was diagnosed with NBD. A total of 35 patients were diagnosed with NBD (mean age 27.56 ± 10.36 years; [2.88:1; Male: Female]). The main clinical features of NBD were headaches, weakness, unsteadiness, and dysarthria. The most commonly involved sites on imaging were the brainstem, diencephalon, cerebellum and basal ganglia. Oligocolonal bands were negative in all patients. Maintenance therapy most commonly included oral corticosteroids, azathioprine, and/or infliximab. Most patients received pulse corticosteroids alone when presenting with acute relapse. Half of our cohort was asymptomatic and three in four had favorable outcomes.

CONCLUSION

NBD is common among patients with BD in our population with most patients having favorable outcomes. Patients might have a wide array of symptoms which might make the diagnosis challenging.

Should trigeminal neuralgia be considered a clinically isolated syndrome?

The association between trigeminal neuralgia (TN) and multiple sclerosis (MS) is well established. Many MS patients with TN have magnetic resonance imaging (MRI) evidence of a symptomatic demyelinating lesion. Although infratentorial presentations are included in the diagnostic criteria for MS, there remains confusion in clinical practice as to whether TN should be considered a clinically isolated syndrome for the application of McDonald criteria. In this case series, we discuss this diagnostic quandary in patients presenting with TN and additional MRI findings suggestive of MS and highlight the unmet need for data in such patients to optimally guide their care.

Septoplasty versus septoplasty with turbinate reduction for nasal obstruction due to deviated nasal septum: a systematic review and meta-analysis

INTRODUCTION

Compensatory inferior turbinate hypertrophy is a common accompanying manifestation in patients with nasal obstruction due to deviated nasal septum (DNS). The grounds for inferior turbinate reduction (ITR) in this population are still not well established. This systematic review and meta-analysis aimed to evaluate the efficacy and safety of septoplasty with ITR versus septoplasty alone.

METHODS

Computerised search in Medline, Embase, and CENTRAL was performed. Eligible for inclusion were randomised controlled trials (RCTs) comparing septoplasty to septoplasty with unilateral, contralateral, ITR in adults with DNS. Primary outcomes were health-related quality of life and nasal patency. The secondary outcome was the occurrence of adverse events. Standardised mean differences (SMD) and odds ratios (OR) with 95% confidence intervals were calculated.

RESULTS

Twelve RCTs that enrolled 775 participants were found eligible. Data were reported at follow-up periods ranging from 1 month to 48 months. The pooled effect estimate showed a statistically significant improvement with unilateral, contralateral, ITR in Nasal Obstruction Symptom Evaluation scale (NOSE) scores. The rate of adverse events was significantly higher with ITR.

CONCLUSIONS

Unilateral reduction of the hypertrophied contralateral inferior turbinate during septoplasty resulted in better subjective relief of nasal obstruction in adults with DNS than septoplasty alone. However, caution is warranted since only few well-designed RCTs were identified.
