The increased height of the skull is addressed in the same procedure. Parts of the flattened occiput are extracted and given a rounder shape by greenstick fracturing them. Pansynostosis/kleeblattschädel
The treatment of pansynostosis comprises the expansion of the anterior cranial vault, as well as the posterior cranial vault. Whilst this may be accomplished in one procedure it is generally performed in two stages. Complications
The most common complications of uncorrected craniosynostosis include increased intracranial pressure, asymmetry of the face, and malocclusion. Asymmetry of the orbits often leads to strabismus. Epidemiology
It is estimated that craniosynostosis affects 1 in 1,800 to 3,000 live births worldwide. three out of every four cases affect males. Sagittal synostosis is the most common phenotype, representing 40% to 55% of nonsyndromic cases, whilst coronal synostosis represents between 20% to 25% of cases. Metopic synostosis is a factor in 5% to 15% of cases, and lambdoid synostosis is seen in 0% to 5% of nonsyndromic cases.Five to 15% of the time more than one suture is involved; this is referred to as "complex craniosynostosis" and is typically part of a syndrome.

Patients report an ongoing battle to distinguish themselves from those with psychiatric disorders, such as delusions of parasitosis and other psychiatric conditions. Pathophysiology
Chronic and repetitive scratching, picking, or rubbing of the nodules may result in permanent changes to the skin, including nodular lichenification, hyperkeratosis, hyperpigmentation, and skin thickening. Unhealed, excoriated lesions are often scaly, crusted or scabbed. Many patients report a lack of wound healing even when medications relieve the itching and subsequent scratching.Patients often:
seek treatment during middle-age, although PN can occur at any age. have a history of chronic severe pruritus. have a significant medical history for unrelated conditions. develop liver or kidney dysfunctions. develop secondary skin infections. have a personal or family history of atopic dermatitis. have other autoimmune disorders. have low vitamin D levels. Diagnosis
Diagnosis is based on visual examination and the presence of itching. A skin biopsy is often performed to exclude other diseases. Lesion biopsies usually show light inflammation, sometimes with increased numbers of eosinophils. A culture of at least one lesion will rule out staphylococcus infection, which has been significantly linked to atopic dermatitis. Treatment
Prurigo nodularis is very hard to treat, but current therapies include steroids, vitamins, cryosurgery, thalidomide and UVB light. In the event that staphylococcus or other infection is present, antibiotics have proven effective, but tend to cause more harm than good for this particular disease. A physician may administer a strong dose of prednisone, which will almost immediately stop the itch/scratch cycle. However, cessation of steroids allows relapse to occur, usually within a few weeks.
