We studied a 17-year-old girl with subacute necrotizing encephalomyelopathy (Leigh syndrome). Lactate and pyruvate levels were increased in serum and cerebrospinal fluid. The oxidation rates of all substrates tested, i.e. pyruvate in liver, and pyruvate, malate and 2-oxoglutarate in muscle, were decreased, as was the production of adenosine triphosphate plus creatine phosphate. Cytochrome content was normal. The data imply a defect in oxidative phosphorylation, outside the cytochrome region.

Anti-neutrophil cytoplasmic antibody-associated vasculitides (AAV) represent a heterogeneous multisystem group of disorders typified by necrotising inflammation of smaller blood vessels, classically yielding a pauci-immune, crescentic glomerulonephritis. Without prompt treatment, there is a significant risk of irreversible damage and ensuing renal impairment.Diagnosis is often challenging, exacerbated by the disorder's often vague and insidious presentation.

Background: Left ventricular unloading is needed in patients on extracorporeal life support (ECLS) with severely impaired left ventricular contractility to avoid stasis and pulmonary congestion, and to promote LV recovery. The presence of thrombi in the LV precludes the use of conventional active unloading methods such as transaortic microaxial pumps or apical LV vents. We describe placement of a vent cannula via the left atrial appendage (LAA) as a useful bailout option.

This report presents two contrasting cases of gallbladder volvulus with distinct pathogenic mechanisms and degrees of torsion. The first case involves a 97-year-old female who presented with acute symptoms and 270° torsion, leading to complete gallbladder necrosis (Gross type II).

Toxic epidermal necrolysis (TEN) is a severe skin reaction caused by extensive epidermal and mucosal necrosis. This clinical phenomenon is known as an acute syndrome of apoptotic pan-epidermolysis (ASAP). The ASAP phenomenon is observed in conditions that mimic TEN, highlighting the challenge in distinguishing these conditions.

Kikuchi-Fujimoto disease (KFD) and adult-onset Still disease (AOSD) are two rare conditions whose association poses a significant diagnostic challenge. KFD is characterized by subacute necrotizing lymphadenitis of unknown etiology, primarily affecting young adults, and often presents with fever and posterior cervical lymphadenopathy. AOSD is a systemic inflammatory disorder of unclear origin, defined by high-spiking fever, lymphadenopathy, hepatosplenomegaly, hyperferritinemia, and leukocytosis.
