Background: Conventional photodynamic therapy (c-PDT) is an effective treatment for actinic keratoses (AKs) and nonmelanoma skin cancer which exploits the photosensitizing properties of methyl aminolaevulinate (MAL). Daylight photodynamic therapy (DL-PDT) is an alternative to c-PDT which does not require the application of MAL in occlusion and that is better tolerated by patients. The impact of occlusion on the efficacy of DL-PD has not been investigated by previous studies.
Objective: To compare the efficacy and tolerability of occlusive and non-occlusive DL-PDT.
Methods: We conducted a prospective intraindividual left/right comparison study. AKs of the face or scalp were marked in two symmetrical treatment areas. The two target areas were randomly assigned to DL-PDT with occlusive and non-occlusive application of MAL. The efficacy and cosmetic outcome were determined by a "blinded" investigator.
Results: Lesions in occluded areas showed a better response in the clearance rate of the lesions (65.5% vs 35.0 %, p < 0.001 %), and cosmetic outcome (P < 0.001). There was no difference in phototoxicity or pain between occluded and non-occluded areas.
Conclusion: The occlusive application of MAL improves the efficacy of DL-PDT in clearing AKs and does not increase the incidence of side effects.

Background/aim: Non-occlusive mesenteric ischemia (NOMI) is a rare and highly fatal disease characterized by intestinal ischemia or necrosis despite the absence of obstruction of the mesenteric vessels. This research aimed to investigate the risk factors for 30-day mortality of NOMI after emergency surgery.
Patients And Methods: We analyzed 42 consecutive patients who underwent emergency surgery for NOMI from April 2015 to August 2022.

Background: Hyaluronic acid (HA) filler-induced vascular occlusion is a serious complication in aesthetic medicine, yet the microvascular behavior of HA gels under physiologically relevant flow conditions remains poorly characterized.
Objectives: To evaluate the embolic fragmentation, dispersal, and occlusive behavior of five commercially available HA fillers within a physiologically calibrated microvascular perfusion model.
Methods: Five HA fillers were tested using a modified PULSAR system incorporating a branched microtubular adapter (200-1000 µm channels) with physiologic arterial flow parameters.

Background And Purpose: Superior sagittal sinus (SSS) dural arteriovenous fistulas (DAVFs) are sinus-type fistulas with shunting point(s) centered on the sinus or parallel parasinus wall, while its counterpart parasagittal DAVFs are non-sinus-type fistulas with shunting point(s) centered on the junctional zone of the bridging vein and the SSS. SSS DAVFs can be challenging to treat due to the widespread shunting zone, eloquence of the involved venous structure and their rarity. We explore the clinical data, imaging characteristics, endovascular treatment modalities and treatment outcomes of SSS DAVF, with the aim of identifying the ideal treatment strategies.

An 81-year-old man was brought to our institution because of general fatigue, loss of appetite, and decreased consciousness. Based on the clinical findings, the patient was diagnosed with diabetic ketoacidosis (DKA) and started on insulin therapy. Two days after normalization of the ketone body level, he developed a high fever and abdominal pain.

Background: Cryoballoon pulmonary vein (PV) isolation (PVI) requires PV occlusion, which can be challenging to the large PV. The non-occlusive separate freezing, which involves freezing the superior and inferior portions of the PV ostium without complete occlusion, is often useful in these situations. This study aimed to evaluate the efficacy and long-term results of the non-occlusive separate freezing technique and compare the treatment details of POLARx and Arctic Front Advance Pro (AFA-Pro).
