All models for incomplete data either explicitly make assumptions about aspects of the distribution of the unobserved outcomes, given the observed ones, or at least implicitly imply such. One consequence is that there routinely exist a whole class of models, coinciding in their description of the observed portion of the data but differing with respect to their "predictions" of what is unobserve...

Pharmacokinetic data from a randomized, parallel-group, multicenter study are presented. Adults with toenail onychomycosis (n = 146) received posaconazole (100 mg, 200 mg, or 400 mg) once daily (QD) for 24 weeks or 400 mg QD for 12 weeks. The posaconazole concentration in the great toenail exhibited a dose-related increase starting at week 2 for 24 weeks and a mean toenail-to-plasma concentrati...

Published data on the prevalence of onychomycosis in psoriasis patients compared with healthy controls are controversial, We therefore conducted a prospective study of toenail onychomycosis, among 113 psoriatic and 106 healthy non-psoriatic subjects, selected from the normal population in the Jerusalem area in the period 2003-05. The results revealed a prevalence of 47.6% toenail onychomycosis ...

Extra-abdominal periosteal desmoid tumors are uncommon nonmetastatic tumors of the extremities with a propensity for local recurrence. Lesions in the distal extremities are rare; a majority of extra-abdominal lesions occur in more proximal portions of the upper and lower extremities. This article reports a patient with an extra-abdominal periosteal desmoid tumor in the toe. A 37-year-old woman ...

Paronychia is an inflammation of the folds of tissue surrounding the nail of a toe or finger. Paronychia may be classified as either acute or chronic. The main factor associated with the development of acute paronychia is direct or indirect trauma to the cuticle or nail fold. This enables pathogens to inoculate the nail, resulting in infection. Treatment options for acute paronychia include war...

Subungual melanoma is uncommon and accounts for just 2% to 3% of all cutaneous melanomas. Less than 10% of subungual melanomas are amelanotic and 90% of these occur on the thumb or great toe. They typically appear in the seventh decade of life and are associated with a delayed diagnosis and a poor prognosis. Amelanotic subungual melanoma generally manifests as a persistent vascular or ulcerated...
