Objectives:Carpal tunnel release surgery has excellent results. The aim of this study was to identify which baseline clinical and demographic factors could predict a good outcome from surgery. Understanding the impact of prognostic factors will enable surgeons to indicate surgical intervention better, provide appropriate preoperative counseling, and manage expectations postoperatively.Materials and Methods:A prospective, observational study included 620 carpal tunnel syndrome patients (age 42.38 ± 11.18 years; mean ± standard deviation). After the diagnosis had been confirmed by electrodiagnostic studies, patients underwent open carpal tunnel release surgery. Patients were evaluated initially after 2 weeks and eventually after 6 months. Surgical outcome was compared with presurgical findings.Results:Response to surgery was good in 89.4% and 94.2% after 2 weeks and 6 months, respectively. Factors correlated significantly with unfavorable outcome of surgery included old age, longer duration of symptoms, negative Phalen's test, abnormal two-point discrimination test, and weakness of abductor pollicis brevis muscle. Gender, retrograde radiation, and nocturnal symptoms did not correlate with surgical outcome.Conclusion:Elderly patients with longstanding disease, neurological deficits, and negative Phalen's test may not respond to surgery as others. This should be kept in mind in preoperative counseling and postoperative expectations.

BackgroundLocal anesthesia could result in lethal complications if injected in highly vascularized area. Dentist should take care to avoid such complications.Case presentationWe present a case of 15 year old girl with a coma following convulsive status epilepticus which developed after inferior alveolar nerve blockade by a dentist. The patient was admitted to the intensive care unit ICU and recovered within several days.ConclusionThis case is reported to tell both of dentists and medical staff that although it is uncommon, such complications of local anesthesia should be in mind to be avoided and managed promptly if happened.

Anti-tumor necrosis factor α (anti-TNF-α) agents have been widely used in the field of autoimmune diseases and have proved decisive efficacy and relative safety. Data concerning their adverse effects has been lately describing central nervous system (CNS) demyelination process at escalating basis. Case Presentation. A 23-year-old male with autoimmune uveitis and a family history of multiple sclerosis (MS) developed two neurological attacks, after Adalimumab infusion, simultaneously with several cerebral lesions on magnetic resonance imaging (MRI). Hence the diagnosis of Adalimumab induced MS was suspected. Conclusion. This case is reported to tell physicians to be cautious when using anti-TNF-α in patients with family history of MS and to reconsider the risk of MS in patients with autoimmune diseases.

Biallelic repeat expansions in replication factor C subunit 1 (RFC1) have recently been found to cause cerebellar ataxia, neuropathy and vestibular areflexia syndrome (CANVAS). Additional features that have been described include Parkinsonism and a multiple system atrophy (MSA)-like syndrome. CANVAS can include features of dysautonomia, but they are much milder than typically seen in MSA. We report a detailed autonomic phenotype of multisystem RFC1-related disease presenting initially as CANVAS. Our patient presented aged 61 with a sensory ataxic neuropathy who rapidly developed widespread autonomic failure and Parkinsonism. The autonomic profile was of a mixed pre-and post-ganglionic syndrome with progressive involvement of sympathetic and parasympathetic cardiovascular and sudomotor function. The Parkinsonism did not respond to levodopa. We present a patient with CANVAS and biallelic RFC1 expansions who developed Parkinsonism with severe autonomic involvement similar to that seen in classical MSA. The link between MSA and CANVAS remains uncertain.

BackgroundLongitudinally Extensive Transverse Myelitis LETM is a specific pattern of myelitis wherein at least three continuous vertebral segments are involved. Characteristically, it is a defining feature of neuromyelitis optica NMO. However, it is described in many other etiologies.Case presentationWe present a case of 60 year old male who presented with symptoms and signs of regional sympathetic dystrophy RSD followed by symptoms of myelitis. Spinal cord MRI revealed cervical LETM extending to the brainstem. In spite of serological negativity, treatment of suspected neuromyelitis optica spectrum disorder NMOSD was initiated and resulted in symptom relief. Meanwhile, sudden death occurred and autonomic dysreflexia was the main culprit.ConclusionsThis case suggests that RSD could be the mere primary presentation of LETM, discusses the differential diagnoses of LETM in elderly patients, and suggests the possible risk of autonomic dysreflexia in such patients.
