Percutaneous Revascularization

Venous arterialization is an increasingly common procedure performed in patients with critical limb-threatening ischemia (CLTI) where there are no open or percutaneous revascularization options. This study aims to review the imaging follow-up for venous arterialization described in the literature. A systematic review was performed on venous arterialization studies for CLTI using the PRISMA methodology. A literature search was performed on 5 databases from inception. We included all original studies, case reports, and reviews regarding venous arterialization for all pathologies. We excluded free standing abstracts, animal studies, other than lower extremity, and foreign language studies. Our search strategy yielded 23 studies that met inclusion criteria, with 16 studies reporting a specific value from at least one surveillance imaging methodology. Most studies used Duplex imaging (16 studies) and TCPo2 (9 studies). Only 9 studies provided any detail regarding the Duplex findings. One study used focal peak systolic velocity (PSV) gradient (PSV at the lesion in the graft divided by PSV in a proximal segment of the graft) above 2.5 as an indicator for flow-inhibiting venous valves or stenosis in the graft. Another study reported a turbulent flow pattern in the graft, elevating peak velocities to 100 to 200 cm/s throughout the bypass. Four studies reported flow volume measurement through the bypass or in pedal vein ranging from 40 to 437 mL/min. Seven studies reported a mean increase of 18.7 mmHg in TCPo2. Eighty-two percent of patients saw an improvement of TCPo2 in 2 studies. To date, no criteria have been identified that are predictive of the success or failure of deep vein arterialization. Venous arterialization is an increasingly common procedure in the “no-option” diabetic patient. Duplex imaging with TCPo2 offers the most appropriate means of surveillance; however, the literature is sparse with no guidance on normal or critical values.

BACKGROUND As current erectile dysfunction (ED) treatments are limited, other treatment such as stem cells should be explored. Hence, this study aimed to review the sources, method of administration, and therapeutic effect of mesenchymal stem cells (MSCs) for diabetic ED treatment. METHODS All relevant articles regarding the use of MSCs for diabetic ED were searched in PubMed and Google Scholar databases from December 15, 2019 to January 1, 2020 published in the past 10 years. The keywords were “mesenchymal stem cells” and “diabetic ED”. The selection and critical appraisal of the studies were discussed. Diabetic ED was evaluated for functional and structural outcome. Functional outcome in animal studies was assessed by intracavernosal pressure/mean arterial pressure (ICP/MAP) ratio, meanwhile the structural outcome was done microscopically. In human study, the assessments were done using international index of erectile function score (IIEF-5) to erection hardness score and penile Doppler ultrasonography. RESULTS There were 10 animal studies and 3 human studies. The studies used MSCs from adipose (n = 6), bone marrow (n = 4), placenta (n = 1), umbilical cord (n = 1), and muscle tissue (n = 1). The MSCs were administrated through intracavernosal injection in all studies. In all animal studies, functional outcome was improved, shown in higher ICP/MAP ratio. Microscopically, there were an increase of cavernosal endothelial cells, vascular endothelial growth factor, nitric oxide synthase, and smooth muscle cells. In human studies, IIEF-5 and erection hardness score were improved. Peak systolic velocity was also higher. CONCLUSIONS MSCs may be a promising therapy for diabetic ED; however, long-term safety concerns still need further investigations.

Abstract Screening

Zirconia is a metal used in dental implantology. Its biocompatibility was studied in vitro and in vivo, results of the studies being analyzed in reviews and meta analyses. The aim of this systematic review was to evaluate biocompatibility of zirconia in animal studies in vivo expressed as results of histomorphometric tests. Databases were searched from 1980 until February 2016, with different combination of the following MeSH terms: zirconium, biocompatibility, dental implants, in vivo, animal studies. Letters to the editors, case reports, commentaries, review articles and articles published in other languages then English were excluded. The search of PubMed, ScienceDirect and Google Scholar databases yielded 690 titles. After abstract screening and duplicate discarding 50 articles were identified and finally, 40 were included in the review. Most of the studies compared zirconia with titanium, a well established material for dental implants. In majority of the studies zirconia showed a similar osseointegration with titanium. Surface implant treatments, like sandblasted and etched zirconia (ZrO2-SLA), alumina toughed zirconia (ATZ), and powder injection molding (PIM) were used to improve osseointegration of zirconia with good results. In the light of histomorphometric test, zirconia, no matter physical and structural forms tested, is a biocompatible material.

Laparoscopic Exploration

The ventriculoperitoneal (VP) shunt is a common procedure in pediatric neurosurgery that carries a risk of complications at cranial and abdominal sites. We report on the case of a child with shunt infection and malfunction. The peritoneal catheter was tethered within the abdominal cavity, precluding its removal. Subsequently, laparoscopic exploration identified a knot at the distal end of the peritoneal catheter around the omentum. A new VP shunt was inserted after the infection was healed. This type of complication occurs rarely, so there are a limited number of case reports in the literature. This report is complemented by a literature review.

Endovascular Balloon Occlusion

Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a hemorrhage control technique that is increasingly being adopted for the management of noncompressible bleeding. In addition to limiting hemorrhage, REBOA increases blood flow to the heart, lungs, and brain. A small number of case reports and animal studies describe the use of REBOA to increase coronary perfusion during cardiopulmonary resuscitation. We report a case in which REBOA may have reversed ST-segment abnormalities during a Type II non-ST elevation myocardial infarction (NSTEMI) in a patient with previous trauma. We describe the presentation, course, and decision making that contributed to the use of REBOA in this case. Additionally, we will present a review of the literature on the effects of REBOA on coronary perfusion.

Alveolar Osteitis

Background: Dry socket is one of the most common post-extraction complications with its incidence reaching up to 30% after impacted third molar extractions. In spite of its high incidence, there is no established treatment for the condition. Objectives: To investigate how efficient different management methods of Alveolar osteitis are, in regards to pain relief, healing process and reduction of the incidence. Materials and Methods: A literature search of “PubMed-MEDLINE” database was conducted using the keywords “dry socket management”, “alveolar osteitis”, “fibrinolytic alveolitis”, “post-extraction complications”. The inclusion criteria were clinical studies, case reports, reviews and human studies, related to alveolar osteitis published from 2011-2016, written in English language. The exclusion criteria were animal studies, studies that discussed other post-extraction complications, and in any other languages than English. Results: 63 articles were found and only 31 were reviewed. 18 out of 31 articles were included in the results, after reading the full text, due to lack of significant results in the rest of the articles. Out of these there were 12 clinical studies, 3 systematic reviews and 1 retrospective study. Conclusion: It was concluded that there is no specific management that could be rated as the best to treat dry socket, due to the lack of evidence to support the use of one management over the other, although there are many options that can help manage it and have proved to be highly effective recently and until today.

Scoping Literature Review

Background Understanding the three-dimensional anatomy of the talar neck is essential in assessing reduction of talar neck fractures, as well as in planning surgical correction for talar malunions. However, the geometrical parameters that describe this anatomy are sparsely reported in the literature. Objectives This review aims to identify from the existing literature, those geometrical parameters that describe the three-dimensional anatomy of the talar neck. Methods A scoping literature review will be conducted in accordance with the PRISMA-ScR guidelines. The primary searches will be conducted on the PubMed, EMBASE and Scopus databases, using a pre-defined search strategy. Any original research study (whether clinical or cadaveric, prospective or retrospective, comparative or noncomparative), looking at the human talus neck geometry or morphology will be included. Studies that do not describe the talar neck geometry, animal studies, review articles, conference abstracts and case reports will be excluded. Geometrical parameters (including techniques to measure these) that describe the three-dimensional anatomy of the talar neck will be identified. Qualitative analysis will be done by means of appropriate tables and diagrams. If feasible, quantitative analysis to determine pooled estimated of geometrical parameters identified in the review will be conducted by a random-effects meta-analysis model. No formal risk-of-bias assessment has been planned, as this is a scoping literature review.
