A graphical method for the description of the spatial extension and temporal development of muscular weakness in neurological disorders implemented on a personal computer is described. Different degrees of paresis of individual muscle groups are represented by distinct grey tone values or colors in a semi-anatomic scheme. This representation provides a rapid recognition of essential features of the clinical syndrome, such as the pattern of muscular weakness and its temporal development. In parallel to the results of force testing, the results of other investigations in the same muscle groups can also be presented by the graphical method.

Muscle disease has various clinical manifestations that range from exertional and non-exertional rhabdomyolysis, fasciculations, weakness, rigidity, stiffness, gait abnormalities, poor performance, and alterations in muscle mass and tone. Neurogenic disorders and non-neurogenic disorders such as primary muscle disease can cause muscle atrophy and changes in muscle tone. Myotonic disorders can have a genetic (eg, inherited channelopathies) or acquired (eg, electrolyte derangements) origin.

The neuromuscular junction (NMJ) is the linchpin of nerve-evoked muscle contraction. Broadly, the function of the NMJ is to transduce nerve action potentials into muscle fiber action potentials (MFAPs). Efficient neuromuscular transmission requires both cholinergic signaling, responsible for generation of endplate potentials (EPPs), and excitation, the amplification of the EPP by postsynaptic voltage-gated sodium channels (Nav1.

A 78-years-old man was treated for asthma and pansinusitis for >5 years, and mepolizumab was initiated two years previously. Two months after the cessation of mepolizumab treatment, the asthma symptoms worsened and acute progressive muscle weakness and sensory disturbance developed. On day 8 after the onset of weakness and hypoesthesia, the patient presented with complete flaccid tetraplegia and diffuse hypoesthesia of all extremities, without paresthesia or pain, and was admitted to our hospital.

Objective: Reduced functional capacity and muscle weakness are two major contributors to functional impairment in chronic obstructive pulmonary disease (COPD). The underlying causes of functional impairment are poorly understood and, therefore, we sought to investigate the contribution of genetic factors.
Methods: We conducted a cross-sectional analysis of sociodemographic, clinical and genetic information of people with COPD.

Late-onset Pompe disease (LOPD) includes patients from 1 year of age to adulthood. The vast heterogeneity in clinical manifestations and disease progression is not fully explained; however, a short disease duration and a young age seem to be good predictors of a better response to treatment. For this purpose, we investigated and followed up a cohort of 13 juvenile patients with LOPD from the clinical and therapeutic point of view, mainly pointing out the transition from presymptomatic to symptomatic status.
