Rhabdomyolysis is a condition in which damaged muscle tissue breaks down and intracellular contents, including myoglobin, are released into the circulation. This produces a nonspecific clinical syndrome including electrolyte disturbances, hypovolemia, metabolic acidosis, coagulopathies, and risk of acute kidney injury. Rhabdomyolysis has been reported as a complication of prolonged surgical procedures but has rarely been reported in the oral and maxillofacial surgery literature. Early diagnosis and treatment of rhabdomyolysis are important to avoid long-term complications such as renal failure...

A 6-month-old male infant with Stuve-Wiedemann syndrome (SWS) presented with an acute respiratory arrest secondary to a rhinovirus respiratory infection from which he was rapidly resuscitated. He developed an acute kidney injury requiring supportive treatment and on day 3 of his illness was noted to have developed severe rhabdomyolysis (creatine kinase level 132 040 U/L (normal <320 U/L)). He was born from consanguineous parents with homozygous mutations in the leukaemia inhibitory factor receptor. He had skeletal dysplasia with metabolic bone disease and episodes of hyperthermia with lactic acidosis...

Food protein-induced enterocolitis syndrome (FPIES) is a non-IgE-mediated gastrointestinal food hypersensitivity triggered by food proteins. It may present acutely, with repetitive vomiting, diarrhoea and lethargy leading to dehydration and eventually shock or insidiously with intermittent emesis, chronic diarrhoea or failure to thrive. We describe a paediatric male patient with recurrent sepsis-like episodes of fever, lethargy, ashen-grey skin colouration and vomiting followed by diarrhoea. These episodes were triggered by cow's milk formula and grains...

Topiramate is a well-known anticonvulsant drug with a broad spectrum of actions. It has been proposed in the treatment of several types of epileptic seizures both in monotherapy and in add-on. Its usage has been extended to other disorders including migraine, essential tremor, obesity, alcohol and drug addiction. The most frequent side-effects of topiramate include dizziness, somnolence, insomnia, and ataxia. Paraesthesia, metabolic acidosis, kidney stones, hypohidrosis, cognitive impairment and eye symptoms have been also reported...

BACKGROUND: Intravenous (IV) arginine has been reported to ameliorate acute metabolic stroke symptoms in adult patients with Mitochondrial Encephalopathy with Lactic Acidosis and Stroke-like Episodes (MELAS) syndrome, where its therapeutic benefit is postulated to result from arginine acting as a nitric oxide donor to reverse vasospasm. Further, reduced plasma arginine may occur in mitochondrial disease since the biosynthesis of arginine's precursor, citrulline, requires ATP. Metabolic strokes occur across a wide array of primary mitochondrial diseases having diverse molecular etiologies that are likely to share similar pathophysiologic mechanisms...

Cystinosis is a rare autosomal recessive disorder resulting from defective lysosomal transport of cystine due to mutations in the cystinosin lysosomal cystine transporter (CTNS) gene. The clinical phenotype of nephropathic cystinosis is characterized by renal tubular Fanconi syndrome and development of end-stage renal disease during the first decade. Although metabolic acidosis is the classically prominent finding of the disease, a few cases may present with hypokalemic metabolic alkalosis mimicking Bartter syndrome...

Vascular calcification such as arteriosclerosis, which is characterized by a calcification of the tunica media, is a severe complication of chronic kidney disease (CKD), contributing to the high prevalence of cardiovascular morbidity and mortality in patients with CKD. An essential step during the development of arteriosclerosis is the transdifferentiation/calcification of vascular smooth muscle cells (VSMCs), resembling osteogenesis. Metabolic acidosis, a common clinical manifestation in CKD, is known to decrease vascular calcification...

Microbiota of the rumen wall constitute an important niche of rumen microbial ecology and their composition has been elucidated in different ruminants during the last years. However, the knowledge about the function of rumen wall microbes is still limited. Rumen wall biopsies were taken from three fistulated dairy cows under a standard forage-based diet and after 4 weeks of high concentrate feeding inducing a subacute rumen acidosis (SARA). Extracted RNA was used for metatranscriptome sequencing using Illumina HiSeq sequencing technology...

REVIEW
Heidi E Karpen
Most bone formation and mineralization occurs late in gestation. Accretion of adequate minerals is a key element of this process and is often interrupted through preterm birth. In utero, mineral transport is accomplished via active transport across the placenta and does not require fetal hormone input. Postnatal mineral homeostasis requires a balance of actions of parathyroid hormone, calcitonin, and vitamin D on target organs. Preterm birth, asphyxia, acidosis, and prolonged parenteral nutrition increase the risk of mineral imbalance and metabolic bone disease (MBD)...

Idiosyncratic drug-induced liver injury (DILI) is ranked among the top most common etiologies of acute liver failure (ALF). It carries poor transplant-free survival. Pirfenidone is an anti-inflammatory and antifibrotic drug that is commonly used for the treatment of idiopathic pulmonary fibrosis (IPF). Hepatotoxicity due to pirfenidone is rare and generally manifests as a mild rise in serum aminotransferases. In this mini-review, we report an unusual case of idiosyncratic DILI due to pirfenidone presenting as ALF, with emphasis on the definition, classification, diagnostic criteria, histopathology, molecular markers, and treatment options for DILI and related ALF...

Calcium channel blockers (CCBs) are prescribed in a wide variety of cardiovascular conditions. Overdose of this commonly used drug can result in negative physiologic consequences including severe hypotension and even death due to metabolic and hemodynamic compromise. We report the fatal case of an amlodipine overdose, which caused intractable acidosis and cardiovascular failure in a 51-year-old male.

Ethylene glycol is a widely used and readily available substance. Ethylene glycol ingestion does not cause direct toxicity; however, its metabolites are highly toxic and can be fatal even in trace amounts. Poisoning is best diagnosed through inquiry, but as an impaired state of consciousness is observed in most cases, poisoning must be suspected when a significantly elevated osmolar gap or high anion gap metabolic acidosis is found in blood tests. Hemodialysis and alcohol dehydrogenase inhibitors such as ethanol and fomepizole are a part of the basic treatment, and timely diagnosis and treatment are crucial because any delays can lead to death...

Brugada phenocopies (BrPs) are clinical entities that differ in etiology from true congenital Brugada syndrome but have identical electrocardiographic (ECG) patterns. Hyperkalemia is known to be one of the causes of BrP. The aim of this study was to determine the clinical characteristics and evolution of hyperkalemia-induced BrP. Data from 27 cases of hyperkalemia-induced BrP were collected from the International Registry at www.brugadaphenocopy.com. Data were extracted from publications. Of the 27 patients included in the analysis, 18 (67%) were male; mean age was 53 ± 15 years (range 31 to 89)...

INTRODUCTION: Classically, hyperkalemia has been regarded as a complication in patients with electrical burns. The etiology of hyperkalemia includes metabolic acidosis, destruction of red blood cells, rhabdomyolysis and the development of renal failure. The purpose of this study was to determine the prevalence of hyperkalemia within the first 24h after electrical burn injury and to evaluate the possible association of serum potassium concentration with cutaneous burn size (%TBSA) and serum creatine phosphokinase (CPK) concentration...

BACKGROUND AND OBJECTIVES: While some case reports indicate that high doses of propylene glycol (PG) may result in metabolic acidosis, there has been no large-scale study that evaluated the risk of metabolic acidosis in patients receiving PG-containing benzodiazepines for acute alcohol withdrawal. This study was undertaken to evaluate the potential toxicity of PG in patients with acute alcohol withdrawal treated with intermittent intravenous bolus doses of diazepam and/or lorazepam. METHODS: This is a retrospective case study using data collected from 18 randomly selected patients receiving one or both of these medications per a modified Clinical Institute Withdrawal Assessment for Alcohol (CIWA) Class 3 protocol...

BACKGROUND: Lactic acidosis (LA) is the most common form of metabolic acidosis, defined by lactate values greater than 5 mmol/L and pH<7.34. The pathogenesis of LA involves hypoxic causes (type A) and non-hypoxic (type B), often coexisting. Identification and removal of the trigger are mandatory in the therapeutic management of LA. The case: A 38 years-old male patient entered the Emergency Ward for dyspnea, fever, vomiting and hyporexia. An important respiratory distress with hyperventilation due to severe LA was found, together with severe hypoglicemia, without renal impairment...
