Background: Ultrasound is widely used in vascular surgery. Pocket-sized ultrasound devices have limited functionality compared to conventional ultrasound scanners, but are cheaper and highly portable. The aim of this study was to investigate whether vascular surgeons could benefit from using a pocket ultrasound device in everyday clinical practice.
Material And Method: Pocket-sized ultrasound devices were made available in the Department of Vascular Surgery at St. Olavs Hospital, Trondheim University Hospital, for a 10-month period. Eleven doctors participated and were free to choose between a conventional ultrasound scanner and a pocket ultrasound device. After each use of a pocket ultrasound device, participants completed a form describing the indication for use, whether the clinical question was answered, the image quality experienced and the need for supplementary diagnostic imaging. At the end of the study period, each user completed a questionnaire.
Results: Pocket ultrasound devices were mainly used preoperatively. The clinical question was answered in 51 (85 %) of 60 registered examinations with a pocket ultrasound device. Image quality was subjectively rated as good in 32 (53 %) examinations, moderate in 21 (35 %) and poor in 7 (12 %), with the clinical question answered in 94 %, 90 % and 29 % of cases, respectively. Doctors with less than five years of experience with ultrasound chose pocket ultrasound more frequently than more experienced users.
Interpretation: For the examinations selected, the images supplied by the pocket ultrasound device were generally of sufficient quality and often answered the clinical question. Pocket ultrasound devices can be a useful supplementary tool in vascular surgery, especially for venous examinations.

Aim: The present study aimed to evaluate the accuracy of noninvasive cone beam computed tomography (CBCT) in the estimation of periodontal bone defects and compare it with that of measurements obtained by invasive surgical exploration using open flap debridement procedure for the evaluation of bony topography.
Materials And Methods: Bone defects in 384 sites with moderate-to-severe periodontitis from eight patients were considered. Probing depth was measured in the following six sites in the selected teeth: mesiobuccal (MB), mesiopalatal (MP)/mesiolingual (ML), buccal (B), palatal (P)/lingual (L), distobuccal (DB) and distopalatal (DP)/distolingual (DL).

Introduction: There are numerous reasons for underutilization of the public health sector for surgery in Pakistan. This results in patients being diverted to private hospitals or tertiary care centers in urban areas. Diversions overburden the hospitals and significantly increase out-of-pocket costs for the patients.

Background: The current study aimed to assess the clinical and radiographic outcomes of the effect of subgingival application of ozonated gel as an adjunct to scaling and root planing (SRP) in diabetic patients with stage III periodontitis.
Methods: Twenty-four patients with type II diabetes mellitus (DM) were randomized into two groups, with 12 patients in each group. Group I served as the intervention group, receiving both SRP and ozone gel application (SRP + Ozone), while Group II served as the control group, undergoing SRP alone.

Article Synopsis
- This study evaluated the outcomes of the SMILE Xtra technique for patients with thin corneas at risk for keratectasia, involving 53 patients with myopia.
- It found significant improvements in uncorrected visual acuity and stable refractive results over 12 months, with no cases of keratectasia or major complications reported.
- The initial decrease in central corneal thickness and mild post-operative symptoms resolved within a week, indicating that SMILE Xtra is a viable option for those with thin corneas.

Objective: Pulsenmore ES is a self-scanning ultrasound system for remote fetal assessment. It is composed of a hand-held transducer that serves as a smartphone cradle coupled with an application and clinician's web-viewer dashboard. Recently, a novel capability was added to the system allowing for offline fetal heart rate (FHR) and maximal vertical pocket (MVP) measurements.
