OBJECTIVE The Prevalence of Actinic Keratoses Italian Study (PraKtis) was designed to estimate the point prevalence of actinic keratoses (AKs) and associated factors in a representative sample of the Italian adult population. DESIGN A representative sample of people 45 years or older was selected from the electoral rolls according to a stratified random sampling design. SETTING A total of 1...

Actinic keratosis (AK) may be an early stage of carcinoma in situ and invasive carcinoma. Excision or destruction of AKs is one of the most frequently performed procedures in dermatology. The most common treatments for AKs in the United States are liquid nitrogen cryotherapy and 5-fluorouracil. This paper focuses on the topical 5% fluorouracil cream (Efudex), 1% fluorouracil cream (Fluoroplex),...

The AKS (Agrawal-Kayal-Saxena) algorithm is the first ever deterministic polynomialtime primality-proving algorithm whose asymptotic run time complexity is O(log n), where > 0. Despite this theoretical breakthrough, the algorithm serves no practical use in conventional cryptologic applications, as the existing probabilistic primality tests like ECPP in conjunction with conditional usage of sub-...

BACKGROUND Actinic keratoses (AKs) are precursors to invasive squamous cell carcinoma and can progress if untreated. Limited data support the use of ingenol mebutate to treat AKs on more than one area of the body simultaneously. OBJECTIVE To investigate safety, efficacy and treatment satisfaction when treating separate areas simultaneously or sequentially with different concentrations of inge...

The most famous lattice problem is the Shortest Vector Problem (SVP), which has many applications in cryptology. The best approximation algorithms known for SVP in high dimension rely on a subroutine for exact SVP in low dimension. In this paper, we assess the practicality of the best (theoretical) algorithm known for exact SVP in low dimension: the sieve algorithm proposed by Ajtai, Kumar and ...

A current obstacle to the observation system simulation experiments (OSSEs) used to quantify the potential performance of future atmospheric composition remote sensing systems is a computationally efficient method to define the scene-dependent vertical sensitivity of measurements as expressed by the retrieval averaging kernels (AKs). We present a method for the efficient prediction of AKs for m...

BACKGROUND Cryosurgery is the most commonly used method to treat actinic keratosis (AK). Cryosurgical methods are not standardized. OBJECTIVE To examine differences in the spray techniques used for liquid nitrogen cryosurgery when treating AKs of the head, and the effect of these variations in technique on rates of complete clearance of AKs. MATERIALS AND METHODS Patients were those from th...

OBJECTIVES To compare patient self-report of knee flexion, extension, range of motion (ROM) and American Knee Society (AKS) Pain, Knee and Functional scores with a clinician assessment. METHODS A total of 239 consecutive total knee arthroplasty (TKA) patients (290 knees) were mailed surveys with an AKS questionnaire and lateral knee photographs that showed knee ROM in 10 degrees increments to...

Actinic keratoses (AKs) are common skin lesions heralding an increased risk of developing squamous cell carcinoma (SCC) and other skin malignancies, arising principally due to excessive ultraviolet (UV) exposure. They are predominantly found in fair-skinned individuals, and increasingly, are a problem of the immunosuppressed. AKs may regress spontaneously, remain stable or transform to invasive...

Actinic Keratoses (AKs) are epidermal skin lesions that have the potential to develop into squamous cell carcinoma. Many of the treatment options available can cause discomfort, pain or skin irritation. Topical 3% diclofenac in 2.5% hyaluronan gel (Solaraze, Bioglan Pharma) is a relatively new treatment that has been shown to be effective and well tolerated for the treatment of AKs.
