Abstract
The use of immune reconstitution therapies (IRT) in patients with relapsing-remitting multiple sclerosis (RRMS) is associated with a prolonged period of freedom from relapses in the absence of continuously applied therapy. Cladribine tablets is a disease-modifying treatment (DMT) indicated for highly active relapsing multiple sclerosis (MS) as defined by clinical or imaging features. Treatment with cladribine tablets is effective and well tolerated in patients with active MS disease and have a low burden of monitoring during and following treatment. In this article, an expert group of specialist neurologists involved in the care of patients with MS in the United Arab Emirates provides their consensus recommendations for the practical use of cladribine tablets according to the presenting phenotype of patients with RRMS. The IRT approach may be especially useful for patients with highly active MS insufficiently responsive to treatment with a first-line DMT, those who are likely to adhere poorly to a continuous therapeutic regimen, treatment-naïve patients with high disease activity at first presentation, or patients planning a family who are prepared to wait until at least 6 months after the end of treatment. Information available to date does not suggest an adverse interaction between cladribine tablets and COVID-19 infection. Data are unavailable at this time regarding the efficacy of COVID-19 vaccination in patients treated with cladribine tablets. Robust immunological responses to COVID-19 infection or to other vaccines have been observed in patients receiving this treatment, and treatment with cladribine tablets per se should not represent a barrier to this vaccination.

Abstract
For decades, the Expanded Disability Status Scale (EDSS) has been the principal measure of disability in clinical trials in patients with multiple sclerosis (MS) and in clinical practice. However, this test is dominated by effects on ambulation. Composite endpoints may provide a more sensitive measure of MS-related disability through the measurement of additional neurological functions. The MS Functional Composite (MSFC) includes a walking test (25-ft walk) plus tests of upper extremity dexterity (9-hole peg test) and cognitive function (Paced Auditory serial Addition test [PASAT]). Replacing PASAT with the Symbol Digit Modality test, a more sensitive test preferred by patients, may improve the clinical utility of the MSFC. In addition, disease-specific measures of QoL may be used alongside the MSFC (which does not include measurement of QoL). Clinical data suggest that disease-modifying therapies may delay or prevent relapse, and better composite measures will be valuable in the assessment of disease activity-free status in people with MS.

Abstract
OBJECTIVE Cricopharyngeal myotomy as an independent procedure has been performed on fourteen patients with a variety of neuromuscular disorders, suffering from neurogenic oropharyngeal dysphagia in the interval between 1994-1997. All of them were referred from a neurophysician or physiatrist after failure of improvement by medical treatment. METHODS The selection of patients for operation was based mainly on clinical evaluation and simple exclusion criteria without manometric studies. RESULTS There was dramatic improvement in twelve, with recurrent laryngeal nerve palsy and temporary pharyngeal fistula in two patients. No mortality was recorded. CONCLUSION We conclude that cricopharyngeal myotomy is a simple, safe and effective procedure with acceptable morbidity. It should be considered as a rehabiliation procedure for patients with dysphagia due to various neurologic disorders based on simple, clinical exclusion criteria without the need for the tedious, time consuming and expensive manometric studies.

Abstract
Reversible electrophysiologic abnormalities of sensory nerve function were found by chance in three patients with hypokalemic periodic paralysis, a disorder previously considered to affect the function of muscle membranes only. A formal, prospective study was therefore conducted. Serial nerve conduction studies were done in ten additional patients. Amplitude of sensory action potentials was significantly smaller during paralytic attacks, but did not differ from controls after normalization of serum potassium concentration. These apparently novel findings might be explained by previous electrodiagnostic studies either not involving the testing of sensory nerves at all, or not being repeated after recovery from an attack. Involvement of sensory nerves in hypokalemic periodic paralysis is suggested to arise through dorsal root ganglia having an incomplete blood-nerve barrier and sensory neurons being particularly vulnerable to derangements affecting nerve cell metabolism. Neuronal inexcitability is postulated to occur consequent upon possible inactivation of the sodium-potassium pump by the low concentration of extracellular potassium. In patients with acute areflexic limb weakness, the diagnosis of hypokalemic periodic paralysis should not be excluded by abnormal results of sensory nerve conduction studies.

Abstract
In a previous retrospective study, 4 of 9 patients with benign intracranial hypertension were unexpectedly positive for intrathecal synthesis of immunoglobulin (Ig) G by quantitative measurement (log IgG index). This was remarkable as the only disease among many studied that showed such a discrepancy. A further study was done, now prospectively. Log IgG index values were elevated in 2 of the 11 new cases. As before, qualitative measurement (isoelectric focusing) gave uniformly negative results. Five of the 6 instances where the log IgG index was elevated could be accounted for, in fact, by abnormal values of constituent variables other than cerebrospinal fluid IgG. Quantitative tests for intrathecal synthesis of IgG can give misleading results on their own. Immunological mechanisms most probably are not involved in the pathogenesis of benign intracranial hypertension.
