The Percent Volume Altered in Correction of Myopia and Myopic Astigmatism With PRK, LASIK, and SMILE.

Purpose: To determine the volumes altered during photorefractive keratectomy (PRK), laser in situ keratomileusis (LASIK), and small incision lenticule extraction (SMILE) correction of myopia and myopic astigmatism.

Methods: The volumes of stromal tissue affected by surgical correction of pure and astigmatic myopia were calculated in this theoretical study for PRK, LASIK, and SMILE treatments. These results were then used to calculate representative values for percent volume altered (PVA) restricted to stromal corneal tissue.

Octenidine in combination with polymethylmethacrylate: a new option for preventing infection?

Background: Orthopedic implant infections represent a serious complication for both patient and surgeon. In order to minimize this risk, it has become standard practice in surgery and orthopedics to add antimicrobial substances to the polymethylmethacrylate (PMMA) bone cement. The aim of this study is to find new options for preventing infection by using alternative adjuvants in combination with PMMA.

Integrated FDG-PET-CT: its role in the assessment of bone and soft tissue tumors.

Purpose: The purpose of this study was to evaluate prospectively, whether integrated 2-deoxy-2-[(18)F]fluoro-D: -glucose positron emission tomography-computed tomography (FDG-PET-CT) is more accurate for determination musculoskeletal tumors compared with separate interpretation of CT and FDG-PET, because most of the current clinical data come from patients studied with PET.

Methods: Eighty patients with newly diagnosed musculoskeletal tumors underwent FDG-PET-CT. CT, FDG-PET, and FDG-PET-CT were interpreted separately to determine the performance of each imaging modality.

First efficacy and safety study of femtosecond lenticule extraction for the correction of myopia: six-month results.

Purpose: To prospectively study the feasibility of femtosecond lenticule extraction (FLE), a new method of refractive correction.

Setting: Department of Ophthalmology, Philipps University of Marburg and Helios Clinic, Erfurt, Germany.

Methods: A flap and a lenticule of intrastromal corneal tissue were simultaneously cut with a VisuMax femtosecond laser system.

Imaging bone and soft tissue tumors with the proliferation marker [18F]fluorodeoxythymidine.

Purpose: We have determined the ability of positron emission tomography (PET) with the thymidine analogue 3'-deoxy-3'[18F]fluorothymidine (FLT) to detect manifestation sites of bone and soft tissue tumors, to assess tumor grading, and to differentiate malignant from benign tumors.

Materials And Methods: In this prospective bicenter trial, FLT-PET was done in 22 patients with established or suspected soft or bone tissue lesions. Routine diagnostic procedures included incisional biopsy, magnetic resonance imaging, and/or contrast-enhanced spiral computed tomography in all patients and [18F]fluorodeoxyglucose (FDG)-PET in 15 patients.

Nonsteroidal anti-inflammatory drugs (NSAIDs) in the perioperative phase in traumatology and orthopedics effects on bone healing.

Objective: To achieve analgesic, anti-inflammatory and antipyretic effects in traumatology and orthopedic surgery without side effects or with the least possible side effects, with special emphasis on bone healing.

Indications: Acute and chronic inflammatory conditions, e. g.
