Article Abstract
We developed a spectrally-encoded, line reflectance confocal microscope (RCM) that uses a rotating diffuser to rapidly modulate the illumination speckle pattern. The speckle modulation approach reduced speckle noise while imaging with a spatially coherent light source needed for high imaging speed and cellular resolution. The speckle-modulation RCM device achieved lateral and axial resolutions of 1.1 µm and 2.8 µm, respectively. With an imaging speed of 107 frames/sec, three-dimensional RCM imaging over 300-µm depth was completed within less than 1 second. RCM images of human fingers, forearms, and oral mucosa clearly visualized the characteristic cellular features without any noticeable speckle noise.

Chromatin dynamics play a crucial role in cellular differentiation, yet tools for studying global chromatin mobility in living cells remain limited. Here, a novel probe is developeded for the metabolic labeling of chromatin and tracking its mobility during neural differentiation. The labeling system utilizes a newly developed silicon rhodamine-conjugated deoxycytidine triphosphate (dCTP).

Department of Dermatology, Henry Ford Health, Detroit, MI, USA.
Background: Reflectance confocal microscopy (RCM) criteria for in vivo diagnosis of unperturbed basal cell carcinoma (BCC) lesions have been validated and studies have reported high diagnostic sensitivity. However, a paucity of data remains regarding preservation or changes in RCM features after biopsy or treatment.
Objective: Prospectively image biopsy proven superficial BCC (sBCC) with RCM at baseline and 12 weeks post-treatment to determine clearance and identify any associated RCM features.
Case Report: IVCM of corneal chlorpromazine toxicity drug deposits.

To investigate corneal deposits in a patient undergoing long-term chlorpromazine therapy using confocal microscopy with the HRT II Rostock Corneal Module. We reported a 45-year-old woman with a 7-year history of chlorpromazine therapy presented with bilateral photophobia and a 4-year history of gradual-onset blurred vision. Slit-lamp examination revealed yellowish deposits in the corneal endothelium and Descemet's membrane.

Background: Scarring, particularly the atrophic type, is one of the most distressing consequences of acne. Despite the availability of various treatment options, no single best treatment option has been recognized.
Objective: To compare the efficacy of carbon dioxide (CO2) pinhole method and needleless microsubcision with hyaluronic acid (HA) to identify a more effective treatment option for acne atrophic scars.

Introduction: Peri-implantitis (PI) is a biofilm-related condition driven by bacterial colonization on dental implant surfaces, leading to inflammation of the peri-implant connective tissue and progressive bone loss. Despite advancements, effective strategies for eradicating these biofilms remain elusive. While high-intensity focused ultrasound (HIFU) has been popularized in medicine, its effects on dental implant-attached biofilms remain unclear.
