Liver Transplant and Incisional Hernia: What Do We Know and What Can We Improve.

Background: During follow-up, incisional hernias can reduce the quality of life of transplant recipients. The objective was to analyze the incidence of incisional hernia and risk factors to detect improvements.

Methods: Retrospective study of transplant recipients between 2002 and 2021.

Long-term results with biosynthetic absorbable P4HB mesh in ventral abdominal wall repair: a multicentre analysis.

Background: The aim of this multicentre study was to analyse the outcomes of biosynthetic absorbable poly-4-hydroxybutyrate (P4HB) prosthesis implantation in patients undergoing ventral hernia repair (VHR) in the context of different degrees of contamination.

Methods: From May 2016 to December 2021, a multicentre retrospective analysis of patients who underwent elective or urgent hernia repair with P4HB prosthesis was performed in seven hospitals in Spain and Portugal. Patients with a postoperative follow-up of less than 20 months and those within the theoretical period of prosthesis resorption were excluded from the study.

A phase II, single-center, double-blind, randomized placebo-controlled trial to explore the efficacy and safety of intravenous melatonin in surgical patients with severe sepsis admitted to the intensive care unit.

To determine whether IV melatonin therapy improves redox status and inflammatory responses in surgical patients with severe sepsis, a unicenter, phase II double-blind, randomized, placebo-controlled trial was carried out. The study included patients with severe sepsis marked by infectious systemic inflammatory response syndrome (SIRS), associated with organ dysfunction, hypoperfusion or hypotension requiring surgical intervention. IV melatonin at a daily dose of 60 mg, which was dissolved in 500 ml of 5% dextrose serum, was continuously administered to the patients for over 30 min starting on the day of the diagnoses during a 5-day period.

[Traumatic diaphragmatic rupture].

Traumatic diaphragmatic rupture is an infrequent lesion that can result from penetrating or blunt trauma to the abdomen or chest. Early diagnosis continues to be a challenge and this type of injury is associated with high morbidity and mortality. Preoperative diagnosis is difficult and a high level of suspicion, careful scrutiny of the chest x-ray, and early surgical treatment are required for successful management.

Positron-emission tomography with fluorine-18-fluoro-2-deoxy-D-glucose for gallbladder cancer diagnosis.

Background: Recent advances in hepatobiliary surgery have underscored the need for presurgical diagnosis of gallbladder cancer. Frequently, clinical presentation, biochemical analysis, and structural ultrasound or computed axial tomography images do not enable definitive differentiation of cholecystitis or cholethiasis from gallbladder cancer. The aim of this study was to evaluate the role of fludeoxy glucose-positron-emission tomography (FDG-PET) in establishing the benign or malignant nature of gallbladder lesions.

[Giant renal angiomyolipoma].

We present a case report of a renal angiomyolipoma with the special feature of its big size at the moment of the diagnosis. It is appreciated an important alteration of the kidney morphology and the repercussion produced in the rest of the abdominal organs. Due to this an exeresis with nefrectomy is performed.

Effect of pretreatment with interleukin-1 beta on inflammatory infiltrates and tissue damage after experimental endotoxic challenge.

Objective: To evaluate the effect of treatment with murine recombinant interleukin-1 beta on inflammatory infiltrate and tissue damage after experimental endotoxic challenge.

Design: Randomized, controlled study.

Setting: Experimental Unit, Virgen de las Nieves University Hospital.

[Leiomyosarcoma of the bladder. Report of a new case and review of the literature].

Contribution of a new case of bladder leiomyosarcoma due to the rarity of its presentation. There are barely one hundred cases reported in the medical literature. Clinico-pathological, therapeutic and prognostic assessment of this type of bladder sarcoma and discussion on the convenience of complementary therapy after surgery.

Differential effects of IL-1 beta and ibuprofen after endotoxic challenge in mice.

Interleukin-1 (IL-1) and ibuprofen modulate the host response in different models after endotoxic challenge. A comparative study was made between the two drugs, as they were jointly administered, to explore a potentiation of their therapeutic effects. Endotoxic challenge was provoked in CBA/H mice with lipopolysaccharide (LPS) from Escherichia coli (125 mg/kg), with administration of recombinant murine IL-1 beta (80 ng/mouse) 24 hr pre-LPS.

Interleukin-1beta and ibuprofen effects on CD4/CD8 cells after endotoxic challenge.

Multiple-organ failure is considered a consequence of autodestructive inflammatory response during which a state of immunosuppression is produced. Alterations in CD4 and CD8 lymphocytes after experimental endotoxic challenge and their correlation with the protective effects of interleukin-1beta (IL-1beta) and ibuprofen pretreatment were investigated. CBA/H mice were injected with lipopolysaccharide (LPS) of Escherichia coli (125 mg/kg); 40 mice were pretreated with IL-1beta (80 ng/mouse, 24 hr pre-LPS), 40 with ibuprofen (1 mg/kg 1 hr pre-LPS, 1 mg/kg 30 min post-LPS), and 40 with both drugs (same doses and timing).
