TLDR
Management consisted of anticholinesterase medication in 81% for a mean of 21 days and general care, particularly respiratory care, especially respiratory care for the mothers, who all had generalized myasthenia gravis.Abstract:
Two male infants with neonatal myasthenia gravis are described. The serum of one patient and his myasthenic mother had no neuromuscular blocking activity or antinuclear globulin. Striation binding globulin was positive in the serum of the mother, but not the infant. Eighty two collected patients are reviewed. Incidence was 12% of babies born to myasthenic mothers. Onset was within 72 hours of birth. Mean duration was 18 days and maximum was 47 days. Nine patients died, with a mean duration of 6 days and a maximum of 21 days. The remaining patients recovered without recurrence, except for recurrence at 2 years in one patient. Manifestations were feeding difficulty (87%), generalized weakness (69%), respiratory difficulty (65%), feeble cry (60%), and facial weakness (54%), including ptosis (15%). Pharmacologic tests with neostigmine or edrophonium were positive in 86%. Management consisted of anticholinesterase medication in 81% for a mean of 21 days and general care, particularly respiratory care. The mothers all had generalized myasthenia gravis. Four mothers did not receive anticholinesterase medication and nine had undergone thymectomy. Eleven mothers subsequently had a second affected child, and five mothers had a normal child. There was no relation of neonatal myasthenia to striation binding or antinuclear globulin in serum of mother or infant.read more

Serum Globulin in Myasthenia Gravis: Inhibition of α-Bungarotoxin Binding to Acetylcholine Receptors
TL;DR: In this paper, the authors showed that at least 5 and possibly 11 out of 15 patients with myasthenia gravis showed inhibitory activity localized to the globulin fraction, which may explain the involvement of the immune system in the pathophysiology of the neuromuscular junction.

The natural course of myasthenia gravis: a long term follow up study.
TL;DR: A long term follow up study is presented of 73 patients with myasthenia gravis, living in Amsterdam between 1926 and 1965, and the evolution of their clinical state represents the natural course of MG.

Establishment of patient-derived cancer organoids for drug-screening applications
TL;DR: An overview of the protocols used by different groups to establish organoids from various epithelial tissues and cancers, plus the different protocols subsequently used to test the in vitro therapy sensitivity of these patient-derived organoids are provided.

Anti-acetylcholine receptor antibodies.

TL;DR: Analysis of clinical, immunological and HLA antigen characteristics in MG suggest that more than one mechanism may underlie the breakdown in tolerance to AChR, leading to the production of anti-AChR antibodies.

Humoral antibodies to acetylcholine receptor in patients with myasthenia gravis
TL;DR: Sera from patients with myasthenia gravis were studied by the quantitative micro-scale complement-fixation assay for the presence of humoral antibodies against acetylcholine receptor (AChR), and such antibodies may have significance in producing the neuro-muscular block characteristic of the disease.
