This report presents a case of necrotizing fasciitis following a seemingly minor injury sustained from handling a spiny plant. Despite initial primary care by a physician, the patient presented with severe septic shock and necrotizing fasciitis of the hand, necessitating emergency surgical intervention. The use of scoring systems aided in the prompt recognition of the condition.

Introduction: Necrotizing fasciitis (NF) is a critical disease with high morbidity and mortality rates that poses significant challenges in diagnosis and treatment. Prognostic factors for the clinical course of NF remain unclear and are currently under research. This study aims to identify such factors in a large cohort of patients which represents a major comprehensive investigation of prognostic factors for NF.

This case report presents a rare complication after percutaneous needle fasciotomy for Dupuytren contracture: the development of epidermoid cysts. A 60-year-old man who had previously undergone a needle fasciotomy required a subsequent limited fasciectomy due to disease progression. Unexpectedly, epidermoid cysts were discovered during the procedure.

Necrotizing fasciitis is a rare yet severe complication after body contouring surgery. We present a case of a 54-year-old woman with a complex medical history who developed necrotizing fasciitis 9 days after panniculectomy and epigastric hernia repair. Microbiological examination revealed as the causative agent, a rare pathogen in necrotizing fasciitis.

Necrotizing fasciitis (NF) is a life-threatening and rare condition. However, we report and analyze a remarkably high number of NF cases during the coronavirus disease 2019 (COVID-19) pandemic and especially in the first months after the COVID-19 pandemic. We conducted a retrospective analysis of 17 cases of NF treated in our clinic between January and May 2023.

Macrophage migration inhibitory factor (MIF) and its homolog, D-dopachrome tautomerase (D-DT), are cytokines that play critical roles in the immune response to various infectious diseases. This review provides an overview of the complex involvement of MIF and D-DT in bacterial, viral, fungal, and parasitic infections. The role of MIF in different types of infections is controversial, as it has either a protective function or a host damage-enhancing function depending on the pathogen.

Radial polydactyly or thumb duplication is a relatively common congenital malformation of the hand, whereby the surgical techniques can be broadly divided into simple excisions, reconstructions and a Bilhaut-Cloquet procedure. The aim of this study was to identify the appropriate surgical procedures and to present the clinical outcomes that can be achieved. We performed a multicenter analysis of cases of radial polydactyly surgically treated with reconstruction or a Bilhaut-Cloquet procedure between 2015 and 2022.

Background: Necrotising fasciitis (NF) represents a rare but often life-threatening condition. Early diagnosis and surgical treatment are of vital importance. The LRINEC score was developed to distinguish necrotising fasciitis from other soft tissue infections (STI) at initial evaluation using six laboratory values.

Necrotizing fasciitis (NF) is a potentially fatal soft tissue infection. Four types of pathogens can be distinguished in the pathogen spectrum, although there are strong regional differences with regard to the most common pathogens. All cases of NF between 2003 and 2021 with an identified causative agent were analyzed retrospectively.

Necrotizing fasciitis is a potentially fatal soft tissue infection in which the timing of surgical intervention significantly affects clinical outcome. The Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) score, the Site other than the lower limb, Immunosuppression, Age <60 years, Renal impairment (creatinine >141), and Inflammatory markers (CRP ≥150, WCC >25) (SIARI) score, and procalcitonin levels are intended to aid in the decision-making process to differentiate between necrotizing fasciitis and soft tissue infections. A retrospective analysis of cases of necrotizing fasciitis and soft tissue infections treated at Klinikum Nürnberg was performed.

(1) Background: Microsurgical reconstruction of foot defects with free flaps is rare as it is a challenging task for a surgeon. For extensive defects, advanced surgical procedures, such as free flap transfer with microsurgical anastomosis, may be the last chance to avoid major amputation. The aim of the study was to examine the opportunities and risks posed by free flap reconstruction of foot defects and to illustrate in which situations reconstruction is useful on the basis of case characteristics.

In general, matrices for tissue engineering must maintain structural integrity during the process of tissue formation and promote vascularization of developing tissue. Therefore, collagen sponges, manufactured by an approach that offers the potential of unidirectional pore size, were seeded with human umbilical vein endothelial cells (HUVEC) to demonstrate a positive effect on cell proliferation. In addition, vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) have been used to promote proliferation of HUVEC on optimized collagen sponges.

(1) Background: Nowadays, the use of microsurgical free flaps is a standard operative procedure in reconstructive surgery. Still, thrombosis of the microanastomosis is one of the most fatal postoperative complications. Clinical evaluation, different technical devices and laboratory markers are used to monitor critical flap perfusion.

Intoxication with carbon monoxide in organisms needing oxygen has probably existed on Earth as long as fire and its smoke. What was observed in antiquity and the Middle Ages, and usually ended fatally, was first successfully treated in the last century. Since then, diagnostics and treatments have undergone exciting developments, in particular specific treatments such as hyperbaric oxygen therapy.

Background: Integrative medicine focuses on the human being as a whole-on the body, mind, and spirit-to achieve optimal health and healing. As a synthesis of conventional and complementary treatment options, integrative medicine combines the pathological with the salutogenetic approach of therapy. The aim is to create a holistic system of medicine for the individual.

Diaphragmatic hernia (DH) after a liver resection (LR) is an uncommon but potentially severe complication. In this retrospective study, we aim to share our experience with DH in our hepatic surgery center. We retrospectively analyzed 3107 patients who underwent a liver resection between January 2012 and September 2019.

Nuck's hydroceles, which develop in a protruding part of the parietal peritoneum into the female inguinal canal, are rare abnormalities and a cause of inguinal swelling, mostly resulting in pain. They appear when this evagination of the parietal peritoneum into the inguinal canal fails to obliterate. Our review of the literature on this topic included several case reports and two case series that presented cases of Nuck hydroceles which underwent surgical therapy.
