INTRODUCTION: Decompressive craniectomy and craniotomy are among the most common procedures in Neurosurgery. In recent years, increased attention has focused on the relationships between incision type, extent of decompression, vascular supply to the scalp, cosmetic outcomes, and complications. Here, we review the current literature on scalp incisions for large unilateral front-temporo-parietal craniotomies and craniectomies. METHODS: Publications in the past 50 years on scalp incisions used for front-temporo-parietal craniectomies/craniotomies were reviewed...

INTRODUCTION: The emergence of multi-drug-resistant bacteria is one of the main concerns in the health sector worldwide. The conventional strategies for treatment and prophylaxis against microbial infections include the use of antibiotics. However, these drugs are failing due to the increasing antimicrobial resistance. The unavailability of effective antibiotics highlights the need to discover effective alternatives to combat bacterial infections. One option is the use of metallic nanoparticles, which are toxic to some microorganisms due to their nanometric size...

INTRODUCTION: Coronary artery bypass grafting (CABG) is an essential surgical management modality for patients with coronary artery disease. Health-related quality of life (HRQoL) has become important because of the significant decrease in the mortality rate associated with CABG. We aimed to explore the factors that affect the quality of life after CABG. METHODS: This study used a descriptive correlational design to assess the determinants of HRQoL using the 36-item Short Form Health Survey questionnaire (SF-36)...

BACKGROUND: Iatrogenic vascular injuries (IVIs) due to diagnostic and therapeutic interventions are known but rare or probably under-reported. We present our four-year findings on patients with IVIs after catheterization or surgery who underwent vascular surgical repairs in a resource-limited setting. METHODS: A retrospective case series study between Jun 2018 and Sep 2022 of 35 patients diagnosed with IVIs and treated surgically at our hospital was included. The data on IVIs including patient characteristics, causes and type of injury, treatment, and outcomes were collected and analyzed...

BACKGROUND: Obesity is a well-known predictor for poor postoperative outcomes of vascular surgery. However, the association between obesity and outcomes of thoracic endovascular aortic repair (TEVAR) is still unclear. This systematic review and meta-analysis was performed to assess the roles of obesity in the outcomes of TEVAR. METHODS: We systematically searched the Web of Science and PubMed databases to obtain articles regarding obesity and TEVAR that were published before July 2023...

BACKGROUND: The contractile phenotype of vascular smooth muscle cells (VSMCs) results in good diastolic and contractile capacities, and its altered function is the main pathophysiological basis for diseases such as hypertension. VSMCs exist as a synthetic phenotype in vitro, making it challenging to maintain a contractile phenotype for research. It is widely recognized that the common medium in vitro is significantly less crowded than in the in vivo environment. Additionally, VSMCs have a heightened sense for detecting changes in medium crowding...

BACKGROUND: Infra-malleolar disease is present in most diabetic patients presenting with tissue loss. Infra-malleolar (pedal) artery disease and pedal medial arterial calcification (pMAC) are associated with major amputation in patients with chronic limb-threatening ischemia (CLTI). This study aimed to examine the impact of pMAC on the outcomes after isolated infra-malleolar (pedal artery) interventions. METHODS: A database of lower extremity endovascular intervention for tissue loss patients between 2007 and 2022 was retrospectively queried...

OBJECTIVE: This study aimed to compare the influence of inframalleolar (IM) P0/P1 on wound healing in bypass surgery versus endovascular therapy (EVT) in patients with chronic limb-threatening ischemia (CLTI). METHODS: We retrospectively analyzed the multicenter data of patients who underwent infra-inguinal revascularization for CLTI between 2015 and 2022. IM P represents target artery crossing into foot, with intact pedal arch (P0) and absent or severely diseased pedal arch (P1)...

BACKGROUND: In the event of an advanced rectal carcinoma, an evisceration with rectal amputation may become necessary. The resulting defects, due to their extent, depth, or local tissue damage from previous surgeries and radiation, can in many cases only be closed through free microvascular tissue transfer. In this case series, we demonstrate the successful combination of a musculocutaneous musculus vastus lateralis flap (MVL) with a direct connection to the superior gluteal artery. MATERIALS AND METHODS: Over a 47-month period, we retrospectively examined 11 cases of patients with dorsal pelvic defects after evisceration and rectal amputation that could not be closed using local or regional means...

When angiosarcoma, a rare and aggressive tumor of the soft tissue, develops in the setting of chronic lymphedema, it is referred to as Stewart-Treves syndrome. It is usually seen in chronic lymphedema of the upper limbs postmastectomy. Angiosarcoma developing in the lower limb in the setting of chronic lymphedema is rare and has a poor outcome. The presentation of angiosarcoma can vary, ranging from a bleeding papule to a plaque or a subcutaneous mass, which can later progress to ulceration or necrosis. Treatment for Stewart-Treves syndrome is aggressive because of its poor prognosis and usually requires a multidisciplinary approach of surgery, radiation, and chemotherapy...

BACKGROUND: In this study, we explored the potential of human adipose tissue-derived extracellular matrix (adECM) sheets augmented with crosslinked hyaluronic acid (HA) as advanced wound dressings. We aimed to enhance healing efficacy while optimizing cost efficiency. METHODS: The adECM was processed from healthy donor tissue and combined with crosslinked HA to form ECM-HA sheets (Scaffiller, Medikan, Korea). In vitro experiments involved seeding adipose-derived stem cells (ASCs) onto these sheets and assessing cell survival and cytokine production...

Bevacizumab, an anti-vascular epidermal growth factor inhibitor, is approved for the treatment of various cancers. Hypertension, gastrointestinal perforation, bleeding manifestations, impaired wound healing, and cerebrovascular accidents are common side effects associated with the monoclonal antibody. Uncommon cutaneous reactions like exfoliative dermatitis associated with bevacizumab have been documented in the medical literature. We present an unusual case of bevacizumab-induced cutaneous lupus in a patient with metastatic colon cancer that started resolving after discontinuing chemotherapy...

The timely restoration of lost blood in hemorrhaging patients with trauma, especially those who are hemodynamically unstable, is of utmost importance. While intravenous access has traditionally been considered the primary method for vascular access, intraosseous (IO) access is gaining popularity as an alternative for patients with unsuccessful attempts. Previous studies have highlighted the higher success rate and easier training process associated with IO access compared with peripheral intravenous (PIV) and central intravenous access...

OBJECTIVES: The objective of this study was to analyze all available research on the application of autologous fat grafting (AFG) and adipose-derived stem cells (ADSC) to present evidence-based recommendations, particularly in the clinical treatment of acute burns and burn-related scars. MATERIALS AND METHODS: We conducted a systematic search of PubMed, COCHRANE, and EMBASE, as well as a manual search of previous reviews' reference lists up. The risk of bias (RoB) was assessed using RoB 2...

BACKGROUND: The goals of reconstruction have progressed from filling a defect to enhancing function and aesthetic appearance. We aimed to achieve better aesthetic and functional outcomes in terms of shoe fitting and mobility. This is accomplished via a classification of the subunits and aesthetic considerations of the lower limb. METHODS: Between April 2017 and December 2021, 66 cases of lower extremity free fasciocutaneous flap reconstruction cases were included in this retrospective study...

This study investigates the impact of perioperative tourniquet on skeletal muscle cells during total knee arthroplasty (TKA) and its effects on the gene expression of apoptotic, inflammatory, and angiogenic pathways. The randomized controlled trial included 44 patients undergoing TKA. The patients were randomized to undergo surgery with (n = 23) or without (n = 21) tourniquet. The tourniquet was inflated before skin incision and deflated before wound closure in the tourniquet group...

A man in his 50s was stabbed deeply in the back with a knife and brought to the emergency room. He was found to have a significant left hemopneumothorax. He was planned to undergo hemostatic surgery under general anesthesia. However, shortly after the change in a right lateral decubitus position, he experienced ventricular fibrillation. Hemostasis of the intercostal artery injury, the source of bleeding, and suture of the injured visceral pleura were performed under extracorporeal membrance oxgenation( ECMO)...

PURPOSE: To assess the utility of frailty in predicting outcomes following surgical intervention for KDs. METHODS: The NIS database was queried for non-congenital knee dislocations from 2015 to 2019 that underwent ligament repair or surgical reduction. Patients were assigned frailty scores using the mFI-11, and outcomes were compared. Multivariate regression and ROC curve analysis were used to assess the independent association of obesity, frailty, VI, and age with adverse outcomes...

When skin is damaged or affected by diseases, it often undergoes irreversible scar formation, leading to aesthetic concerns and psychological distress for patients. In cases of extensive skin defects, the patient's life can be severely compromised. In recent years, 3D printing technology has emerged as a groundbreaking approach to skin tissue engineering, offering promising solutions to various skin-related conditions. 3D bioprinting technology enables the precise fabrication of structures by programming the spatial arrangement of cells within the skin tissue and subsequently printing skin replacements either in a 3D bioprinter or directly at the site of the defect...
