Myasthenia gravis (MG) is an autoimmune disease related to the production of autoantibodies. It is mediated by antibodies against acetylcholine receptor (AChR), muscle specific kinase (MuSK) or other AChR related proteins in the postsynaptic muscle membrane, which interfere with the transmission of signals at the neuromuscular junction, resulting in clinical symptoms of skeletal muscle weakness and fatigue, leading to the occurrence and development of MG. At present, the incidence rate of Mg is increasing year by year. At present, the method of invigorating spleen, replenishing qi and tonifying kidney in traditional Chinese medicine has been widely used in the clinical treatment of MG, and the effect is good. The purpose of this study was to systematically evaluate the efficacy and safety of the method of invigorating the spleen, supplementing qi and tonifying the kidney in the treatment of MG. ⋯ The purpose of this study was to evaluate the efficacy and safety of the method of invigorating the spleen, supplementing qi and tonifying the kidney in treating MG, and to provide evidence based medicine.

Crohn's disease is a chronic inflammatory condition that can involve any area in the gastrointestinal tract often involving the distal ileum where vitamin B12 is specifically absorbed. The aim of this study was to ascertain serum vitamin B12 and folate levels in order to investigate the correlation among these vitamin levels and disease activation, localization, duration and age at the onset of the disease. Study population included 103 patients with Crohn's disease and a healthy control group of 114 individuals. ⋯ The intragroup analysis of the patient group revealed that low vitamin B12 levels were significantly lower in the moderate group classified according to the Crohn's Disease Activity Index (P < .001), along with those in the L1 group with terminal/distal ileal involvement (P < .001). Vitamin B12 and folate deficiencies are quite prevalent in patients with Crohn's disease while this condition can lead to various complications and they prove to be important risk factors associated especially with thrombosis and its complications. Patients must be regularly followed-up for vitamin B12 and folate levels to supplement them where needed.

Over the last year, with the social isolation imposed by the coronavirus disease pandemic, there has been a significant increase in complaints associated with physical violence against women. In the present study, an exploratory literature review was carried out on the role of the on-call orthopedic surgeon when faced with a suspicion of domestic violence, in accordance with Brazilian legislation. The main objective of the study was to show the role of this specialist in identifying victims of domestic violence by recognizing their profiles and associated risk factors. ⋯ Head and neck injuries are the most frequently observed lesions in this population, with more than one-third of victims reporting falls. Musculoskeletal injuries are present in up to 42% of victims of domestic violence, occurring predominantly in the upper limbs and chest, and are the leading cause of death in women aged 1 to 34 years. A practical guide for orthopedic surgeons who work in emergency departments is proposed, with basic information about their role and responsibility in identifying potential victims of intimate partner violence.

Review Case Reports
Neonatal maple syrup urine disease case report and literature review.
The main clinical symptoms of maple syrup urine disease (MSUD) are dehydration, acidosis, nervous system symptoms and intellectual disability. The brain imaging findings were mainly caused by cytotoxic edema. The lesions usually occur at the site consistent with the myelination process of normal neonates. The distribution is mostly symmetric, and the diffusion is obviously limited. ⋯ MSUD in neonates is rare. Our case report and literature review was aim to describe the clinic and imaging characteristics of it, and highlight physicians must be aware of this entity in newborns so as to reduce misdiagnosis due to unfamiliarity.

Multicenter Study
Pilot study to estimate the safety and effectiveness of hydroxyurea and methotrexate recurrent langerhans cell histiocytosis (LCH-HU-pilot).
This study was a non-blinded, multicenter, single-arm study. Recurrent (relapsed) LCH is defined as the appearance of new lesions or the enlargement of preexisting lesions due to LCH. ⋯ The primary endpoint was the rate of non-active disease achievement, which was 24 weeks after initiating hydroxyurea administration. No active disease is defined as the resolution of all the signs and symptoms related to LCH.
