Nodular fasciitis of the periorbital soft tissue in an adolescent confirmed by USP6 gene rearrangement.

Nodular fasciitis is a benign, idiopathic condition that can simulate both benign and malignant neoplasms. In adults, it generally occurs in the subcutaneous or superficial fascia of the trunk or upper extremities; occurrence in the periorbital region is far less common. We describe a case of a 16-year-old male with a 4-month history of a nodular, non-tender, progressively enlarging mass of the superotemporal periorbita.

Amplitude degradation of thin layer in neutron logging.

The paper presents an analysis and discussion of the problem of underestimation of neutron signal amplitude in profiling of the thin-layers rock media. The corresponding neutron profiles were modeled using the Monte Carlo method, and the formalism of the general neutron parameter GNP was used to analyze the results. We show that the degradation of the thin layer signal amplitude depends on the layer thickness, and on the difference in the neutron properties of the layer and its surrounding medium.

Primary Atypical Lipomatous Tumor of the Orbit: A Case Report.

Purpose: To describe a case of primary atypical orbital lipomatous tumor (ALT).

Case Report: A 35-year-old man presented with a two-month history of left eye proptosis and vertical diplopia. His visual acuity was 20/30 OD and 20/60 OS.

EXPERIMENTAL AND MONTE CARLO INVESTIGATIONS OF BCF-12 SMALL‑AREA PLASTIC SCINTILLATION DETECTORS FOR NEUTRON PINHOLE CAMERA.

Plastic organic scintillators such as the blue-emitting BCF-12 are versatile and inexpensive tools. Recently, BCF-12 scintillators have been foreseen for investigation of the spatial distribution of neutrons emitted from dense magnetized plasma. For this purpose, small-area (5 mm × 5 mm) detectors based on BCF-12 scintillation rods and Hamamatsu photomultiplier tubes were designed and constructed at the Institute of Nuclear Physics.

An Unusual Case of Blepharochalasis.

Purpose: To describe a rare case of blepharochalasis that progressed from unilateral to bilateral involvement at five years after disease onset.

Case Report: A previously healthy five-year-old white boy presented to our hospital for a screening visual examination. He was found to have a 2-mm right eyelid ptosis with crepe-like skin and subcutaneous telangiectatic vessels.
