Isolating Potentiated Hsp104 Variants Using Yeast Proteinopathy Models

Many protein-misfolding disorders can be modeled in the budding yeast Saccharomyces cerevisiae. Proteins such as TDP-43 and FUS, implicated in amyotrophic ...

We report an intra-articular ganglion cyst (IAGC) presenting as knee pain and a mass in a patient with longstanding Juvenile Idiopathic Arthritis (JIA). We could not find a similar case of an IAGC occurring in the knee of JIA patients in the literature. IAGC may need to be included as a possibility in patients with inflammatory arthritis with new-onset knee pain, especially in those with a palpable mass. MRI was useful in distinguishing IAGC from more worrisome causes of a knee mass. Orthopedic input was helpful in diagnosis and treatment. In addition, methotrexate therapy was effective in bringing about a long-lasting remission.

An intra-articular ganglion cyst in a patient with juvenile idiopathic arthritis.

We describe a possible association between pulmonary hemosiderosis (PH) and a history of bronchopulmonary dysplasia (BPD). Both patients were born at 28-week gestation and presented with PH at ages 22 months and 6 years, respectively. Both initially presented with cough and tachypnea, and bronchoalveolar lavage showed evidence of hemosiderin-laden macrophages. Initial hemoglobin levels were < 4 g/dL and chest radiographs showed diffuse infiltrates that cleared dramatically within days after initiation of intravenous corticosteroids. In the first case, frank pulmonary blood was observed upon initial intubation, prompting the need for high frequency ventilation, immediate corticosteroids, and antibiotics. The mechanical ventilation wean was made possible by the addition of mycophenolate mofetil (MMF) and hydroxychloroquine. Slow tapering off of medications was accomplished over 6 years. These cases represent a possible correlation between prematurity-associated BPD and PH. We present a review of the literature regarding this possible association. In addition, MMF proved to be life-saving in one of the PH cases, as it has been in pulmonary hemorrhage related to systemic lupus erythematosus. Further studies are warranted to investigate the possible association between PH and prematurity-related BPD, as well as the use of MMF in the treatment of PH.
