Treating Psoriatic Arthritis to Target: Defining the Psoriatic Arthritis Disease Activity Score That Reflects a State of Minimal Disease Activity.

Objective: The Psoriatic Arthritis Disease Activity Score (PASDAS) is a composite disease activity measure (range 0-10) for psoriatic arthritis (PsA). We aimed to validate a cutoff value of PASDAS that defines minimal disease activity (MDA) state, as well as to validate previously defined PASDAS cutoffs for low and high disease activity.

Methods: Patients were prospectively recruited from the University of Toronto PsA clinic according to a standard protocol, and variables necessary to complete the PASDAS and the MDA were collected.

Development of a Modified Psoriatic Arthritis Disease Activity Score Using the Medical Outcomes Study Short Form 12 as a Measure of Quality of Life.

Objective: The Psoriatic Arthritis Disease Activity Score (PASDAS) is a composite measure of psoriatic arthritis (PsA) disease activity. The length of its patient-reported components raises concern about questionnaire burden. The PASDAS includes the Medical Outcomes Study Short Form 36 (SF-36) health survey.

[Pneumatocele caused by ballistic injury of the anterior stage of the skull base, a case report].

The authors present a case of intracerebral expansive pneumatocele following a ethmoido-sphenoidal fracture by a bullet. The case presented is exceptional, as the bullet went through the brain case without injuring the neurological structure. The patient is operated on through the low paralateronasal approach, by filling the ethmoid and the sphenoid with autologous bone material.

Nonresident macrophages are absent from glomeruli in IgA nephropathy.

The presence of nonresident cells of monocyte-macrophage lineage was investigated in 50 renal biopsies, including 20 from patients suffering from IgA nephropathy. Histochemical and immunological techniques were used to identify, respectively, nonspecific esterase and peroxidase activities and HLA class II molecules. Although intraglomerular phagocytes were observed in all control biopsies, small numbers were seen in only two samples from patients with IgA nephropathy.

[Meningeal hemorrhage, a symptom disclosing spinal tumor in children].

One case of subarachnoid haemorrhage due to a spinal cord tumor, seen in a child, is reported. This exceptional etiology, whose the look is often misleading must be called to mind when meningeal and rachidian syndromes are associated. Ependymoma of cauda equina is the most common tumor.
