BACKGROUND Low-complement urticarial vasculitis is an uncommon condition associating urticaria, glomerulonephritis, obstructive ventilatory disorders, and anti-Ciq antibodies. CASE REPORT We report a case in a 34-year-old woman who developed urticaria with purpura, membranoproliferative glomerulonephritis (creatinine 238 mumol/l) and bronchial obstruction with bronchectasia. Total complement and the C3 fraction were low. Anti-C1q antibodies were found in the serum and anti-DNA antibodies were negative. Aggravation of the respiratory and renal failure progressed despite corticosteroid therapy, leading to death at 4 months. DISCUSSION Bronchial obstruction in low-complement urticarial vasculitis results from emphysema and is often life-threatening. Our case exhibited an unusual feature due to the lack of radiodetectable emphysema, the presence of bronchectasia and the rapid degradation of the respiratory function.

Trisomy 13 syndrome (Patau syndrome) is a disorder of human chromosomes which occurs in approximately 1 in 10,000-25,000 live-born infants. Trisomy refers to three copies of a chromosome instead of the normal two and in Trisomy 13 there is the presence of an extra #13 chromosome. Approximately 80% of infants with Trisomy 13 syndrome will have a full trisomy (affecting all cells) while the remainder will have a trisomy due to a rearrangement of cells called a translocation (an attachment of all or part of one chromosome to another chromosome) or have mosaicism (two different cell lines in an individual).

GENERAL CHARACTERISTICS: Rare cause of cutaneous ulceration, pyoderma gangrenosum is among the group of neutrophilic dermatites characterized by the richness of the mature neutrophilic polynuclear dermal infiltrate. The primary lesion is a pustule sitting on an inflammatory base; extremely painful, it rapidly ulcerates. The lesion rapidly extends to more than 10 cm in diameter, has a regular, sharp border and a peripheral roll of flesh exhibiting purulent channels on the inside and a red granulous surface often covered with a pustular coating. Little is known of this disease. CONCOMITANT AFFECTIONS: In more than 50% of cases, pyoderma gangrenosum is associated with other diseases, which must be systematically searched for. These may be digestive, essentially inflammatory enterocolitis with frequent development of peristomal ulceration, rheumatismal affections notably rheumatoid arthritis, hematological affections (benign monoclonal gammapathy, chronic myeloid hemopathy). FROM A PARACLINICAL POINT OF VIEW: There are no specific examinations. A cutaneous biopsy should be performed in all cases, notably to eliminate other causes of ulceration. Since concomitant disease can be subsequently revealed, it is essential to renew the paraclinical investigations, even after the disease has healed. NO CODIFIED TREATMENT: Treatment of the cause, if it can be cured, may be sufficient to permit regression of the lesions. Local treatments to provoke budding and hence avoid surinfection are mandatory. In the progressive and extensive forms, systemic treatment, notably high dose corticosteroids, is indicated. Surgery, a priori, is excluded.

Osteogenesis imperfecta is a genetic disorder that causes increased bone fragility and low bone mass. Osteogenesis imperfecta is a rare disease: its estimated prevalence is between 1/10000 and 1/20000 persons. The severity of skeletal and extraskeletal manifestations varies widely. Most patients have a mutation in one of the 2 genes that encode the alpha chains of collagen type I. Treatment with bisphosphonates has produced clear improvements, especially for growing children. The appropriate regimen for bisphosphonate treatment remains to be determined: the goal is to find the lowest effective dose to minimize side effects. Treatment of osteogenesis imperfecta must be multidisciplinary, including physicians, surgeons, and physical therapists.

Takayasu arteritis is an inflammatory arteritis affecting large vessels, predominantly the aorta and its main branches. Thickening of the vessel wall is an early hallmark of the disease and leads to stenosis, thrombosis, and sometimes aneurysm formation. Reported incidence ranges from 1.2 to 2.6/million/year. Women aged 20 to 40 are most likely to suffer from the disease than men. Manifestations are very polymorphous, with presentations ranging from asymptomatic to neurologic catastrophes. Prognosis depends essentially on complications (retinopathy, hypertension, aneurysm, aortic insufficiency) and initial disease aggressivity. Diagnosis is based on imaging methods. Doppler ultrasound, computed tomography, and magnetic resonance imaging are fast and reliable methods for assessing vessel anatomy and luminal status. Positron emission tomography with fluorodeoxyglucose appears to be a highly sensitive and effective method for detecting disease activity, especially since standard inflammatory markers seem ineffective. Until now, corticosteroids have been the treatment of choice. If remission does not occur, methotrexate is added. Percutaneous transluminal angioplasty and sometimes vascular surgery is necessary in cases of critical ischemia or threatening aneurysm. Duration of treatment, choice of second-line treatment, and protocol for tapering medication currently depend more on experience than on evidence-based medicine. Multicenter studies are needed to guide future practice.

When standing up, gravity moves blood from the upper body to the lower limbs. As a result, there is a temporary reduction in the amount of blood in the upper body for the heart to pump (cardiac output), which decreases blood pressure. Normally, the body quickly counteracts the force of gravity and maintains stable blood pressure and blood flow. In most people, this transient drop in blood pressure goes unnoticed. However, this transient orthostatic hypotension can cause lightheadedness that may result in falls and injury, particularly in older adults.

Rett syndrome is a brain disorder that occurs almost exclusively in girls. The most common form of the condition is known as classic Rett syndrome. After birth, girls with classic Rett syndrome have 6 to 18 months of apparently normal development before developing severe problems with language and communication, learning, coordination, and other brain functions. Early in childhood, affected girls lose purposeful use of their hands and begin making repeated hand wringing, washing, or clapping motions. They tend to grow more slowly than other children and about three-quarters have a small head size (microcephaly). Other signs and symptoms that can develop include breathing abnormalities, spitting or drooling, unusual eye movements such as intense staring or excessive blinking, cold hands and feet, irritability, sleep disturbances, seizures, and an abnormal side-to-side curvature of the spine (scoliosis).
