RESUMEN
Progress in tobacco control policy making has occurred worldwide through advocacy campaigns involving multiple players- civil society groups, activists, academics, media and policymakers. The Framework Convention on Tobacco Control (FCTC)-the first ever global health treaty-outlines evidence-based tobacco control policies. Lebanon ratified the FCTC in 2005, but until 2011, tobacco control policies remained rudimentary and not evidence-based. Beginning in 2009, a concerted advocacy campaign was undertaken by a variety of stakeholders with the aim of accelerating the process of adopting a strong tobacco control policy. The campaign was successful, and Law 174 passed the Lebanese Parliament in August 2011. In this article, we analyse the policy making process that led to the adoption of Law 174 using Kingdon's model. The analysis relies on primary and secondary data sources including historical records of key governmental decisions, documentation of the activities of the concerted advocacy campaign and in-depth interviews with key stakeholders. We describe the opening of a window of opportunity as a result of the alignment of the problem, policy and politics streams. Furthermore, findings revealed that despite the challenge of persistent tobacco industry interference and established power relations between the industry, its allies and policymakers; policy entrepreneurs succeeded in supporting the alignment of the streams, and influencing the passage of the law. Kingdon's multiple stream approach was useful in explaining how tobacco control became an emerging policy issue at the front of the policy agenda in Lebanon.

Familial Mediterranean fever (FMF) was recently associated with a hypercoagulable state. However, clinically overt thrombosis remains a rare event limited to patients with other predisposing factors. We herein present a child with FMF who experienced a stroke. An extensive thrombophilia work-up revealed multiple inherited and acquired risk factors. In areas with high prevalence of prothrombotic mutations and in children who are products of consanguineous marriages, early screening for concurrent thrombotic risk factors is warranted; as this may help design an optimal management plan and prevent unfavourable outcomes.

BACKGROUND AND PURPOSE: Hereditary spastic paraplegia (HSP) is a disorder characterized by degeneration of the corticospinal tracts and posterior column of the spinal cord. Previously described radiologic findings included nonspecific brain abnormalities such as brain atrophy and white matter lesions, as well as atrophy of the spinal cord. In our study, we aimed to better characterize brain and spine MR imaging findings in a series of patients with HSP. MATERIALS AND METHODS: Nine patients from 4 different Lebanese families with the autosomal recessive form of HSP were included in the study. All patients underwent brain and whole-spine MR imaging. We assessed the presence of white matter abnormalities mainly along the corticospinal tracts, brain atrophy, thinning of the corpus callosum, and the presence of spinal cord atrophy or abnormal signal intensity. RESULTS: Imaging revealed mild brain atrophy (44%), atrophy of the corpus callosum (55%), white matter lesions (67%), abnormal T2 high signal intensity in the posterior limb of the internal capsule (55%), and mild spinal cord atrophy (33%). CONCLUSIONS: The MR imaging findings of HSP are nonspecific and variable; however, the most prominent features include atrophy of the corpus callosum, T2 signal intensity in the posterior limb of the internal capsule, and spinal cord atrophy.

The epidemiologic, clinical, radiological and laboratory characterization of multiple sclerosis (MS) is very well documented in Caucasian and Japanese populations, but very little is known about MS in the Arab world. Such knowledge is becoming of paramount importance, with the recent advances in therapies, MRI techniques and other diagnostic procedures. We report a cohort of Lebanese MS patients, including details of their clinical and laboratory characteristics. The medical records of 202 patients fulfilling the Mc Donald's diagnostic criteria, and followed in our tertiary care center were reviewed. This cohort is highly representative of the disease in Lebanon where the number of MS patients is estimated to be between 1200 and 1700. The peak age of onset of MS in our cohort was in the third decade with 62.4% of patients developing their first symptoms between 20 and 39 years. The female/male ratio was 1.8/1.0. A positive family history for MS was present in 5% of patients. The most frequent presenting symptoms were brainstem-cerebellar (46.2%) followed by sensory (42.5%), motor (33.9%) and visual (29.6%). Of the total number of patients, 85.1% had relapsing remitting MS at onset, and 7.9% primary progressive MS. Benign MS defined as EDSS<=2.0 after 10 years from onset was present in 20% of patients. The mean time from onset to secondary progressive MS was around 9 years. Visual, brainstem, and somatosensory evoked potentials were abnormal in 65.6%, 27.8%, and 50.7% of patients tested respectively. Cerebrospinal fluid showed pleocytosis in 32.6%, increased IgG synthesis in 45.2%, positive oligoclonal bands in 40%, and elevated protein in 34% of patients tested. Although some of the clinical characteristics of our MS population were different compared to western series, the natural history of the disease was similar.

Biotin-responsive basal ganglia disease is a rare entity of which 10 cases have been reported in the literature. We report a case of biotin-responsive basal ganglia disease with similarities and differences compared to the previously reported cases by Ozand et al. Our case presented much earlier, was milder and responded better to lower doses of biotin, compared to the cases reported previously. Since our case showed differences with those in the literature, it might represent a new entity or a milder form of the same entity.

We report a 47-year-old female with Sjogren's syndrome (SS) and severe weakness in her lower extremities refractory to cyclophosphamide therapy, who was treated with the monoclonal anti CD-20 antibody rituximab at a weekly dose of 375 mg/m2 for four consecutive weeks. Patient responded within few days of the first dose and her motor power in the lower extremities started to improve gradually along with progressive resolution of the paresthesias and dysesthesias. The improvement was sustained and progressive and eight months after the last dose, she was able to walk for 60 meters without aid or rest. Rituximab may be considered as an effective and promising novel therapy in SS patients with neurological involvement.
