Hypoxemic respiratory failure caused by coronavirus disease 2019 (COVID-19) may lead to prolonged intensive care unit stay and mechanical ventilation. Critically ill patients often develop intensive care unit acquired weakness (ICUAW), which is an umbrella term that encompasses critical illness polyneuropathy and critical illness myopathy. The aim of this paper is to report the clinical, neurophysiological, and radiological findings suggesting critical illness myopathy in three patients with critical COVID-19. L-α-Phosphatidylcholine concentration Muscle magnetic resonance imaging may serve as a diagnostic tool for critical illness myopathy. Weaning failure and generalized muscle weakness with preserved sensation and cranial nerve function should alert physicians for ICUAW.Research on bone diseases often requires investigation of bone gene expression. Isolating high-quality RNA is essential to obtain reliable and accurate gene expression data. In an effort to analyze the expression of genes related to osteoporosis in rat bones, we developed an improved method for extraction of high-quality RNA without the need for liquid nitrogen or specialized equipment. This method involved transitioning frozen bone tissues to a more pliable state with RNAlater ice and pulverization of the samples with a simple homogenizer, followed by a phenol-chloroform-based RNA extraction. Spectrophotometric analysis indicated high purity of the isolated RNA. Electrophoresis on agarose gel revealed two well-defined ribosomal RNA bands. Herein, we present a method that consistently yields RNA of high purity and integrity from rat bone.

Although graduated autonomy is an essential component of residency training, we have an incomplete understanding of resident and attending faculty perceptions of autonomy.

In this study, we assessed differences in perceived autonomy among residents and faculty in pediatrics, internal medicine, and combined internal medicine-pediatrics.

We surveyed senior-level (PGY-2-5) residents and faculty in pediatrics, internal medicine, and combined internal medicine-pediatrics in three large, urban training centers in November 2014. The survey included domain items such as general perceptions of autonomy, case management, rounding structure, and individual resident and faculty factors that may interplay with the granting or receiving of autonomy.

Of 489 eligible respondents, 215 (44%) responded. Internal medicine-pediatrics residents were more likely than categorical pediatrics residents and pediatrics faculty to disagree that they received an appropriate level of autonomy while on inpatient pediatrics general wmbined internal medicine-pediatrics residents' perceptions of autonomy and supervision can help inform future work regarding autonomy-supportive strategies to optimize learning.

Internal medicine-pediatrics residents have differing perceptions of autonomy from their categorical peers as well as categorical supervising faculty. Combined Internal medicine-pediatrics residents' perceived oversight on pediatrics rotations differently from their categorical pediatrics peers and also differently from their experiences on internal medicine wards. A better understanding of combined internal medicine-pediatrics residents' perceptions of autonomy and supervision can help inform future work regarding autonomy-supportive strategies to optimize learning.Thrombotic thrombocytopenic purpura (TTP) is a rare, life-threatening autoimmune or hereditary thrombotic microangiopathy (TMA) that may be difficult to recognize given the wide spectrum of presenting symptoms. The clinical diagnosis of TTP is based on thrombocytopenia, microangiopathic hemolytic anemia and is confirmed by a disintegrin-like and metalloproteinase with thrombospondin type one motif, member 13 (ADAMTS13) less then 10%. However, the latter confirmation is not rapidly available, and treatment is typically initiated based on the degree of clinical suspicion. The PLASMIC score was recently developed to distinguish between TMA patients with and without severe ADAMTS13 deficiency and used as an adjunct in the diagnosis of TTP when the clinical picture is not clear. Here we present the case of a completely asymptomatic female with no past medical history diagnosed with TTP after evaluation for thrombocytopenia found on a routine wellness visit. A high PLASMIC score was crucial in the decision to initiate treatment given an unusual asymptomatic presentation.Skeletal trauma accounts for 10% to 15% of all childhood injuries, with approximately 15% to 30% of these representing physeal injuries. Talus fractures are rare injuries in children with an estimated prevalence of 0.008% of all childhood fractures. Cast immobilization is sufficient treatment for non-displaced fractures, however displaced fractures of the talus require surgical intervention to minimize the risk of trauma-related avascular necrosis (AVN) due to disruption of the vascular supply originating from the talar neck. A 13-year-old boy was brought to the accident and emergency (A/E) department following a road traffic accident while he was pillion riding a bike. Following the accident, he was unable to bear weight on his right foot and his anterior ankle region was swollen, with no neurological deficit or open wound. He had no other injury and no medical or surgical history. On review of the ankle and foot radiographs, he was noted to have a right talar neck fracture with subtalar and ankle dislocation. His computer tomographic (CT) images demonstrated a Hawkins Type IV talus fracture. Initial treatment involved a plaster of Paris (POP) back slab with the ankle in a neutral position. His right leg was elevated on pillows and treated with elevation and ice to alleviate the swelling. As the fracture was comminuted and displaced with ankle and subtalar dislocation, operative intervention (open reduction and fixation of talus with crossed K wires) was planned. The patient was discharged in below knee slab which was changed to a non-walking cast at two weeks. The patient was kept non-weight bearing until fracture united. These types of fractures are rare in children and proper clinical and radiological evaluation is essential. Such fractures should be reduced as early as possible to reduce the ischemia time thus prevent the chances of osteonecrosis. Lastly avoid tourniquets and stable anatomical reduction of fracture is must.
