Observational Study
Prognostic factors for conversion to generalization in ocular myasthenia gravis.
Patients with ocular myasthenia gravis (OMG) are frequently treated to prevent the development of generalized myasthenia gravis (GMG). This retrospective cohort study aimed to assess prognostic factors associated with conversion to GMG. We analyzed the time from the onset of OMG symptoms to GMG in relation to demographic variables, clinical findings, initial investigation results, and treatment regimens using Kaplan-Meier survival curves and multivariate Cox proportional regression analysis. ⋯ Patients with OMG had a low risk of developing GMG. Immunosuppressive treatments may mitigate disease progression. Chest imaging and repetitive nerve stimulation should be routinely performed to assess the risk of generalization.

Case Reports
Intra-arterial chemotherapy for treatment of very low birthweight infants with retinoblastoma: Two case reports.
Intra-arterial chemotherapy (IAC) has been used successfully for unilateral and bilateral eye disease with advanced or less advanced intraocular disease and of children as young as 3 months of age. In this study, we expanded the use of IAC to eyes of two infants with very low birthweight (birth weight of 1000-1500 g) and retinoblastoma. ⋯ Our center for the first time reported the management of retinoblastoma in very low birthweight infants with especially challenging and we recommend this to be useful to the patient community.

Case Reports Observational Study
A novel LMNA indel mutation identified in a family with atrioventricular block and atrial fibrillation.
It is well known that many genetic factors are involved in the occurrence and progression of atrioventricular block (AV block) and atrial fibrillation (AF). However, the genetic variants discovered so far have only explained parts of these processes. More genes and variants remain to be identified. ⋯ By selection of variants absent in the known databases and were predicted to be deleterious, 4 novel variants were identified. Only one novel frameshift insertion in the LMNA gene (c.825_826insCAGG) was identified in another affected family member and not detected in other non-affected family members and the 100 controls. Our finding expanded the spectrum of variants associated with AV block and AF, and was valuable in the genetic diagnosis of AV block and AF.

Acquired cystic disease-associated renal cell carcinoma (ACKD-RCC) is a unique subtype of renal cell carcinoma (RCC) and is found exclusively in patients with end-stage renal disease. We report a case of intracapsular nephrectomy (ICAN) of renal allograft with ACKD-RCC. To our knowledge, this is the first case in Asia of ICAN of renal allograft to treat ACKD-RCC. ⋯ Removal of transplanted kidney with ACKD-RCC using ICAN is feasible to provide a mid-term tumor-free survival for the patient. Therefore, we consider nephrectomy as an early treatment for the nonfunctional cystic allograft kidney, in order to reduce the dosage of anti-rejection drugs, avoid the occurrence of transplanted kidney tumor, and provide the possibility for the patient an opportunity to receive a second kidney transplantation.

Observational Study
Comparison of liver biochemical abnormality between COVID-19 patients with liver cirrhosis versus COVID-19 alone and liver cirrhosis alone: A STROBE observational study.
Coronavirus disease (COVID-19) patients frequently develop liver biochemical abnormality. However, liver biochemical abnormality in COVID-19 patients with liver cirrhosis is under-recognized. Patients hospitalized during COVID-19 pandemic in China (ie, from February to April 2020) were screened. ⋯ None died during hospitalization among the three groups. Liver biochemical abnormality is common in COVID-19 patients with liver cirrhosis. Management of decompensated events in cirrhotic patients without COVID-19 should not be neglected during COVID-19 pandemic.
