Ellbow

The intrinsically disordered scaffold proteins AFF1/4 and the transcription elongation factors ELL1/2 are core components of the super elongation complex required for HIV-1 proviral transcription. Here we report the 2.0-Å resolution crystal structure of the human ELL2 C-terminal domain bound to its 50-residue binding site on AFF4, the ELLBow. The ELL2 domain has the same arch-shaped fold as the tight junction protein occludin. The ELLBow consists of an N-terminal helix followed by an extended hairpin that we refer to as the elbow joint, and occupies most of the concave surface of ELL2...

Positron emission tomography with [(18)F]-fluorodeoxyglucose provides functional and anatomic information by visualising the uptake of radiolabelled glucose in tumour and inflammatory cells. We report delayed diagnosis of necrosis of the gastric fundus after blunt abdominal trauma in a 73-year-old man. After a car accident with head-on collision, the patient was stabilised in our emergency room. His femur was treated by internal fixation, his ellbow was stabilised by a fixateur externe. During surgery his status deteriorated...

Allogeneic BMT was performed in a 33-year-old man because of CML. Donor was his HLA-identical brother. GVHD prophylaxis consisted of short-term MTX and i.v. CsA. On day 17 cutaneous GVHD grade-III developed and high-dose methyl-prednisone was added. Initial daily dose of CsA was 4 mg/kg i.v. CsA dosage was adapted to maintain blood trough levels between 200 and 350 ng/ml. On day 27 the patient developed severe musculoskeletal pain of knees, legs, feet, hands, shoulders and ellbows. Only high-dose opioids and dextropropoxyphen were effective for analgesia...

High-velocity traumas, especially falls from a height, are a major cause of morbidity and mortality in children. Despite the height of fall is a poor predictor of major injury, we must be aware of relevant injuries especially of the head and the musculoskeletal system. The aim is to recognize all relevant problems, or better to avoid the fall. We report a case from a fall of 13.5 meters with an ellbow-fracture and contusions of the head.

Dermatitis herpetiformis Duhring restricted to knees and ellbows is relatively unknown and is called Cottini type. We observed a 23 year old female patient, in whom the resolution of the lesions occured after topical steroids. The dermatitis flared possibly following treatment with an iodine-containing coughing sirup.
