ABSTRACT

Patients with chronic neurological diseases may have predisposing risk factors for severe COVID-19 and should be considered as priority candidates for SARS-CoV-2 vaccination. Nevertheless, the safety of RNA vaccine was evaluated in healthy volunteers or in patients with stable chronic medical conditions excluding patients with chronic neurological diseases. We report here the early tolerability of Comirnaty vaccine in 36 patients with chronic neurological diseases and demonstrate good early tolerability, better than found in healthy people in phase 3 trials.

ABSTRACT

A literature survey of 106 articles shows that standard electrostimulation is an effective treatment of urinary incontinence and urinary disorders with bladder instability. Bladder inhibition is obtained by applying an alternating current at a frequency of between 5 and 25Hz and with a pulse width of between 0.2 and 0.5ms. In 19 articles (including three randomized, placebo-controlled studies), good results were achieved in 60 to 90% of cases, depending on the exact method (i.e. chronic or acute stimulation). Standard electrostimulation is also efficient in stress urinary incontinence. Urethral closure is obtained by applying a 50Hz alternating current with, again, a pulse width of between 0.2 and 0.5ms. In 21 articles (including two randomized, placebo-controlled studies), good results were achieved in 47.5 to 77% of cases. Treatments combining perineal rehabilitation (behavioural education, muscle improvement and biofeed-back) and electrostimulation are reported by 10 authors, with good results in 70 to 80% of cases after 10 to 12 sessions. According to 14 studies, neuromodulation is also an efficient treatment for complex urinary disorders, urgency, pollakiuria and dysuria. The recommended stimulation parameters are a frequency of 10 to 15Hz and a pulse width of 210ms. Good results were found in 34 to 94% of cases (with between 60 and 75% in an international, multicenter study). The overall results different from one study to another because of the need to harmonize stimulation parameters, choice of the study population and treatment follow-up with self-training programs and therapeutic education.

ABSTRACT

3-[(2,2,6,6-Tetramethylpiperidine-4-ylimino)methyl]rifamycin (4) and spin-labeled rifamycin-3-[(2,2,6,6- tetramethyl-1-oxyl-piperidine-4-ylimino)methyl]rifamycin (1) were prepared. The structures of these compounds were determined by IR, UV, MS and 1H NMR of 4. The ESR-spectrum of 1 is a symmetric triplet signal, characteristic of nitroxyl radicals, g = 2.0025. An in vitro comparative study of the cytotoxicity and antitumor activity of 1, 4 and the initial 3-formyl-rifamycin was carried out in concentrations from 0.1 to 0.001 mM on cells before and after oxidative stress (preliminary irradiation 7Gy) on MH3924A-hepatoma rat cells, 293 transformed human fibroblasts, NBK transformed human fibroblasts and HT 1080 human fibrosarcoma. The compounds showed a cytostatic effect to 85%, with 1 being less toxic in the hepatoma cell line. In human melanoma cell lines 1 showed a higher toxicity than 4. All the derivatives (1 and 4) have in vitro antibacterial activity comparable with that of rifampicin.

ABSTRACT

INTRODUCTION: Neuropathy with non-alcoholic thiamine deficiency is reported in the literature, but bladder disorders are rarely detailed. CASE REPORTS: We report two cases of bladder disorders in neuropathy with thiamine deficiency. One patient presented with a flaccid bladder and impaired sensation; the postvoid residual volume was raised. The other patient had reduced bladder capacity, with detrusor hyperreflexia and detrusor-sphincter dyssynergia. In both cases, the bladder disorders disappeared with thiamine supplementation. CONCLUSION: Bladder symptoms may be heterogeneous in nonalcoholic neuropathy. The prognosis is good after vitamin supplementation.

ABSTRACT

INTRODUCTION: Muscular hematomas are frequently reported as a complication of anticoagulation therapy. METHODS: We report six cases of spontaneous muscular hematomas occurring in hemiplegic patients receiving anticoagulation therapy using heparin, low-molecular-weight heparin or fluindione. Anticoagulation therapy was given in prophylactic doses to two patients to prevent deep vein thrombosis and in therapeutic doses to four patients with deep vein thrombosis, pulmonary embolism or cardiac arrhythmia. Two patients experienced episodes of bleeding when heparin and fluindione were temporarily associated. RESULT: Contrary to previous reports, the more frequent site of bleeding was not the ilio-psoas muscle (only 2 patients); hematomas were also observed in hip adductors and gluteus muscles. The most striking finding was the constant location of the hematoma on the hemiplegic side. CONCLUSION: Location on the hemiplegic side can lead to underestimating the frequency of neurologic compression by the hematoma; the diagnosis can nevertheless be established by electromyography. Local signs may not be present, but general signs of hypovolemia and anemia are more frequent. Ultrasound may be the first line investigation but in our experience, the results can be misleading and computed tomography (CT) or MRI are often required to confirm the diagnosis.
