Lung cancer associated with cystic airspaces: A contemporary review.

Lung cancers associated with cystic airspaces (LCCAs) are a rare and relatively novel concept analyzed in various case reports and retrospective studies. In this review, it was our aim to investigate the morphologic, imaging, and clinicopathologic characteristics of this entity, as well as its natural course in light of the current literature. Literature search including the years 2000-2022 was conducted in PubMed.

Spontaneous expulsion of 10 years retained intrathoracic foreign body (bullet) from left main bronchus: A case report.

A foreign body lodged in the tracheobronchial tree is a serious and common medical emergency that can have serious and perhaps lethal consequences. A few cases have been reported in the literature for the last century with gunshot wounds to the chest that were handled non-operatively and finally expelled the bullet on their own. We present a case of a hemodynamically stable 50-year-old male with a 10-year-old penetrating thoracic gunshot wound, with the bullet found in the left main bronchus on computed tomography (CT) scan upon admission.

Simultaneous resection of thymic and bronchial carcinoid tumors in a patient diagnosed with multiple endocrine neoplasia type 1.

Thymic carcinoid tumors are rare tumors which may be associated with multiple endocrine neoplasia type 1. Bronchial carcinoids are also rare tumors and associated with multiple endocrine neoplasia type 1. Coexisting of thymic and bronchial carcinoid tumors in this case is extremely rare.

Spatial and spectral beam shaping with space-variant guided mode resonance filters.

Novel all-dielectric beam shaping elements were developed based on guided mode resonance (GMR) filters. This was achieved by spatially varying the duty cycle of a hexagonal-cell GMR filter, to locally detune from the resonant condition, which resulted in modified wavelength dependent reflection and transmission profiles, across the device aperture. This paper presents the design, fabrication, and characterization of the device and compares simulations to experimental results.

Fiber-optic beam shaper based on multimode interference.

A new method of fiber-optic based beam shaping is investigated both numerically and experimentally. A cylindrically symmetric method of lines (MoLs) is developed to simulate the device. The device is fabricated by fusion splicing a predetermined length of multimode fiber (MMF) to a single-mode fiber.
