Chronic Alcohol Intoxication Is Not Accompanied by an Increase in Calpain Proteolytic Activity in Cardiac Muscle of Rats.

Enzymatic activity of Ca2+-dependent calpain proteases as well as the content and gene expression of μ-calpain (activated by micromolar calcium ion concentrations), calpastatin (inhibitor of calpains), and titin (substrate for calpains) were investigated in cardiac muscles of rats subjected to chronic alcoholization for 3 and 6 months. There was no increase in the "heart weight/body weight" parameter indicating development of heart hypertrophy in the alcoholized rats, while a decreasing trend was observed for this parameter in the rats after 6-month modeling of alcoholic cardiomyopathy, which indicated development of atrophic changes in the myocardium. Fluorometric measurements conducted using the Calpain Activity Assay Kit did not reveal any changes in total calpain activity in protein extracts of cardiac muscles of the rats alcoholized for 3 and 6 months. Western blot analysis did not show reliable changes in the contents of μ-calpain and calpastatin, and SDS-PAGE did not reveal any decrease in the titin content in the myocardium of rats after the chronic alcohol intoxication. Autolysis of μ-calpain was also not verified, which could indicate that proteolytic activity of this enzyme in myocardium of chronically alcoholized rats is not enhanced. Using Pro-Q Diamond staining, changes in phosphorylation level of titin were not detected in cardiac muscle of rats after chronic alcoholization during three and six months. A decrease in µ-calpain and calpastatin mRNA content (~1.3-fold, p ≤ 0.01 and ~1.9-fold, p ≤ 0.01, respectively) in the myocardium of rats alcoholized for 3 months and decrease in calpastatin mRNA (~1.4-fold, p ≤ 0.01) in animals alcoholized for 6 months was demonstrated using real-time PCR. These results indicate negative effect of chronic alcohol intoxication on expression of the abovementioned genes.

Brain Mitochondrial Subproteome of Rpn10-Binding Proteins and Its Changes Induced by the Neurotoxin MPTP and the Neuroprotector Isatin.

Mitochondria play an important role in molecular mechanisms of neuroplasticity, adaptive changes of the brain that occur in the structure and function of its cells in response to altered physiological conditions or development of pathological disorders. Mitochondria are a crucial target for actions of neurotoxins, causing symptoms of Parkinson's disease in various experimental animal models, and also neuroprotectors. Good evidence exists in the literature that mitochondrial dysfunction induced by the neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) influences functioning of the ubiquitin-proteasomal system (UPS) responsible for selective proteolytic degradation of proteins from various intracellular compartments (including mitochondria), and neuroprotective effects of certain antiparkinsonian agents (monoamine oxidase inhibitors) may be associated with their effects on UPS. The 19S proteasomal Rpn10 subunit is considered as a ubiquitin receptor responsible for delivery of ubiquitinated proteins to the proteasome proteolytic machinery. In this study, we investigated proteomic profiles of mouse brain mitochondrial Rpn10-binding proteins, brain monoamine oxidase B (MAO B) activity, and their changes induced by a single-dose administration of the neurotoxin MPTP and the neuroprotector isatin. Administration of isatin to mice prevented MPTP-induced inactivation of MAO B and influenced the profile of brain mitochondrial Rpn10-binding proteins, in which two pools of proteins were clearly recognized. The constitutive pool was insensitive to neurotoxic/neuroprotective treatments, while the variable pool was specifically influenced by MPTP and the neuroprotector isatin. Taking into consideration that the neuroprotective dose of isatin used in this study can result in brain isatin concentrations that are proapoptotic for cells in vitro, the altered repertoire of mitochondrial Rpn10-binding proteins may thus represent a part of a switch mechanism from targeted elimination of individual (damaged) proteins to more efficient ("global") elimination of damaged organelles and whole damaged cells.

Investigation of Salmonella Enteritidis Outbreak Associated with Truffle Oil - District of Columbia, 2015.

On September 8, 2015, the District of Columbia Department of Health (DCDOH) received a call from a person who reported experiencing gastrointestinal illness after eating at a District of Columbia (DC) restaurant with multiple locations throughout the United States (restaurant A). Later the same day, a local emergency department notified DCDOH to report four persons with gastrointestinal illness, all of whom had eaten at restaurant A during August 30-September 5. Two patients had laboratory-confirmed Salmonella group D by stool culture. On the evening of September 9, a local newspaper article highlighted a possible outbreak associated with restaurant A. Investigation of the outbreak by DCDOH identified 159 patrons who were residents of 11 states and DC with gastrointestinal illness after eating at restaurant A during July 1-September 10. A case-control study was conducted, which suggested truffle oil-containing food items as a possible source of Salmonella enterica serotype Enteritidis infection. Although several violations were noted during the restaurant inspections, the environmental, laboratory, and traceback investigations did not confirm the contamination source. Because of concern about the outbreak, the restaurant's license was suspended during September 10-15. The collaboration and cooperation of the public, media, health care providers, and local, state, and federal public health officials facilitated recognition of this outbreak involving a pathogen commonly implicated in foodborne illness.

Mercury Spill Responses - Five States, 2012-2015.

Despite measures to educate the public about the dangers of elemental mercury, spills continue to occur in homes, schools, health care facilities, and other settings, endangering the public's health and requiring costly cleanup. Mercury is most efficiently absorbed by the lungs, and exposure to high levels of mercury vapor after a release can cause cough, sore throat, shortness of breath, nausea, vomiting, diarrhea, headaches, and visual disturbances (1). Children and fetuses are most susceptible to the adverse effects of mercury vapor exposure. Because their organ systems are still developing, children have increased respiratory rates, and they are closer to the ground where mercury vapors are most highly concentrated (2). To summarize key features of recent mercury spills and lessons learned, five state health departments involved in the cleanup (Iowa, Michigan, Missouri, North Carolina, and Wisconsin) compiled data from various sources on nonthermometer mercury spills from 2012 to 2015. The most common sites of contamination were residences, schools and school buses, health care facilities, and commercial and industrial facilities. Children aged <18 years were present in about one third of the spills, with approximately one in seven incidents resulting in symptoms consistent with acute mercury exposure. To protect the public's health after a mercury spill, it is important that local, state, and federal agencies communicate and coordinate effectively to ensure a quick response, and to minimize the spread of contamination. To reduce the number of mercury spills that occur in the United States, public health officials should increase awareness about exchange programs for mercury-containing items and educate school and health care workers about sources of mercury and how to dispose of them properly.

Cannabis arteritis: ever more important to consider.

Cannabis arteritis (CA) is a major and underdiagnosed cause of peripheral arterial disease in young patients. A 34-year-old man, daily smoker of 20 cigarettes and two cannabis cigarettes for 14 years, presented with a necrotic plaque of left hallux for 3 weeks. The Doppler ultrasound and angiography were compatible with severe Buerger's disease. Submitted to a revascularisation procedure and hypocoagulation with rivaroxaban. He had ceased smoking but maintained consumption of cannabis. Owing to the persistence of distal necrosis, amputation of the hallux was performed with good evolution. CA is a subtype of Buerger's disease. It is poorly known but increasingly prevalent and manifests in cannabis users regardless of tobacco use. The drug is considered at least a cofactor of the arteriopathy. The most effective treatment is cessation of consumption. Being cannabis one of the most consumed drugs, its mandatory to ask about its use in all young patients with arteriopathy.

CDC Grand Rounds: Public Health Strategies to Prevent Neonatal Abstinence Syndrome.

Neonatal abstinence syndrome (NAS) is a drug withdrawal syndrome that most commonly occurs in infants after in utero exposure to opioids, although other substances have also been associated with the syndrome (1). NAS usually appears within 48-72 hours of birth with a constellation of clinical signs, including central nervous system irritability (e.g., tremors), gastrointestinal dysfunction (e.g., feeding difficulties), and temperature instability (1) (Box 1). Opioid exposure during pregnancy might result from clinician-approved use of prescription opioids for pain relief; misuse or abuse of prescription opioids; illicit use (e.g., heroin); or medication-assisted treatment (MAT) of opioid use disorder (2) (Box 2).

Heroin-associated anthrax with minimal morbidity.

In 2010, during an outbreak of anthrax affecting people who inject drugs, a heroin user aged 37 years presented with soft tissue infection. He subsequently was found to have anthrax. We describe his management and the difficulty in distinguishing anthrax from non-anthrax lesions. His full recovery, despite an overall mortality of 30% for injectional anthrax, demonstrates that some heroin-related anthrax cases can be managed predominately with oral antibiotics and minimal surgical intervention.

Severe lead toxicity attributed to bullet fragments retained in soft tissue.

A man aged 30 years presented to an emergency department with a 1 month history of severe abdominal pain, jaundice, constipation, lower extremity weakness and weight loss. A peripheral blood smear was performed that showed basophilic stippling of erythrocytes prompting a blood lead level (BLL) evaluation. The patient had a BLL of >200 µg/dL. Retained bullet fragments were identified in the left lower extremity from a previous gunshot wound 10 years prior. Lead from the excised bullet fragment was consistent with the patient's blood lead by isotope ratio analysis. This case is a rare example of a severely elevated BLL attributed to bullet fragments in soft tissue. Bullets retained in soft tissue are not often considered a risk factor for a markedly elevated BLL because they become encapsulated within the tissue over time.

Folic acid ameliorates celecoxib cardiotoxicity in a doxorubicin heart failure rat model.

The cardiotoxic effect of selective cyclo-oxygenase-2 inhibitors is well known. While rofecoxib and valdecoxib have been withdrawn, celecoxib remains on the market. Folic acid, a naturally occurring vitamin, has been shown to reduce myocardial ischemia and post-reperfusion injury in rats.

Yoga and substance use disorders: A narrative review.

Yoga has been utilized for promotion of health and alleviating distress. It has also been used as a therapeutic measure in the field of mental health, including substance use disorders. This narrative review discusses the literature pertaining to use of yoga in the treatment of substance use disorders. The evidence base especially with regards to randomized trials is presented. The possible mechanisms how yoga might be helpful in the treatment of substance use disorders are explored. Subsequently, implications of yoga in clinical practice are elaborated, followed by examination of the issues in interpretation of the literature of published yoga related studies.

Prevalence of dual diagnosis among clinic attending patients in a de-addiction centre of a tertiary care hospital.

Indian research on dual diagnosis is mostly on prevalence of co-morbidity in a particular type of substance use disorder or psychiatric disorder. They were not on overall prevalence of dual diagnosis in a clinical sample. The study aims to assess prevalence of dual diagnosis among first time visitors to a tertiary care deaddiction centre.

What kills everyone, gives a high for some-Recreational Snake Envenomation.

There are multiple reports of recreational snake envenomation describing psychotropic effects in absence of any adverse effects. This is in contradiction with known effects of snake venom. We report a case of a young male who subjected himself to repeated envenomation by a snake purported to be 'Indian Cobra' and experienced a 'high'. However, a direct identification of snake revealed it was a benign 'Rat snake'. We attempt to explain the reported psychological effects as a result of high expectation of rewarding experience, strong suggestion, personality traits and most importantly the dangerous nature of willfully receiving snakebites.

Detection of Histamine in Fish and Fishery Products in Osaka Prefecture (Fiscal 2015 Report).

Histamine food poisoning is caused by ingestion of spoiled fish containing high levels of histamine. This paper reports cases in which histamine was detected in Osaka prefecture in fiscal year 2015 in a survey of fish and fishery products on the market and the food poisoning. A suspected case of histamine food poisoning was also evaluated to investigate the cause and minimize further problems. Histamine in food was separated on SPE cartridge columns, and analyzed after derivatization with fluorescamine by means of HPLC-FL. Histamine was detected in some fishery products on the market and in food that had caused poisoning. The samples in which histamine was detected were semi-dried whole round herring (Urumeiwashi-maruboshi), mackerel (Saba) and sardine dumpling (Iwashi-tsumire). These foods were the main causes of histamine food poisoning according to the report of the Ministry of Health, Labour and Welfare, Government of Japan.

Hepatoprotective effect of Coreopsis tinctoria flowers against carbon tetrachloride-induced liver damage in mice.

Coreopsis tinctoria is a traditional remedy for the management of various diseases including hepatitis. The hepatoprotective role of the plant is not scientifically explored till now. This study was designed to investigate the hepatoprotective potentials of the ethanol extract from C. tinctoria (CTEtOH) using an animal model of carbon tetrachloride (CCl4)-induced acute liver injury.

Rare case of severe serotonin syndrome leading to bilateral compartment syndrome.

The term 'serotonin syndrome' describes a constellation of symptoms caused by serotonergic overstimulation. Its characteristic clinical presentation consists of encephalopathy, neuromuscular signs and autonomic hyperactivity. After removal of the offending agent, the clinical course is usually self-limited but can occasionally lead to severe symptoms. We report the case of a 68-year-old woman who presented emergently with encephalopathy. Home medications included paroxetine and dextroamphetamine/amphetamine. Physical examination revealed tachycardia, tachypnoea, diaphoresis, rigidity, hyperreflexia and clonus. Given the fast onset of symptoms, a diagnosis of serotonin syndrome was made. Laboratory studies showed acute-on-chronic kidney injury and elevated creatine kinase. The patient's mental status quickly returned to baseline with supportive care. Her rhabdomyolysis, however, persisted and led to acute compartment syndrome in her lower extremities. After bilateral leg fasciotomies and treatment of a severe wound infection with intravenous antibiotics, the patient has now recovered with complete resolution of her symptoms.

Dramatic resuscitation with Intralipid in an epinephrine unresponsive cardiac arrest following overdose of amitriptyline and propranolol.

Amitriptyline and propranolol are life threatening in overdose. The efficacy of intravenous lipid emulsion (ILE) in tricyclic antidepressant and propranolol overdose is unclear. We report a dramatic response to ILE following pulseless electrical activity arrest due to mixed amitriptyline and propranolol overdose.

ALDH2 polymorphism and alcohol-related cancers in Asians: a public health perspective.

The occurrence of more than 200 diseases, including cancer, can be attributed to alcohol drinking. The global cancer deaths attributed to alcohol-consumption rose from 243,000 in 1990 to 337,400 in 2010. In 2010, cancer deaths due to alcohol consumption accounted for 4.2% of all cancer deaths. Strong epidemiological evidence has established the causal role of alcohol in the development of various cancers, including esophageal cancer, head and neck cancer, liver cancer, breast cancer, and colorectal cancer. The evidence for the association between alcohol and other cancers is inconclusive. Because of the high prevalence of ALDH2*2 allele among East Asian populations, East Asians may be more susceptible to the carcinogenic effect of alcohol, with most evidence coming from studies of esophageal cancer and head and neck cancer, while data for other cancers are more limited. The high prevalence of ALDH2*2 allele in East Asian populations may have important public health implications and may be utilized to reduce the occurrence of alcohol-related cancers among East Asians, including: 1) Identification of individuals at high risk of developing alcohol-related cancers by screening for ALDH2 polymorphism; 2) Incorporation of ALDH2 polymorphism screening into behavioral intervention program for promoting alcohol abstinence or reducing alcohol consumption; 3) Using ALDH2 polymorphism as a prognostic indicator for alcohol-related cancers; 4) Targeting ALDH2 for chemoprevention; and 5) Setting guidelines for alcohol consumption among ALDH2 deficient individuals. Future studies should evaluate whether these strategies are effective for preventing the occurrence of alcohol-related cancers.

Management of Patients on Abuse-Deterrent Opioids in the Ambulatory Surgery Setting.

The use of prescription opioids for acute and chronic pain has become more prevalent than ever, and concurrent with the increased prescribing of opioids, there has been a steady increase in opioid abuse. Abuse is commonly associated with physical or chemical manipulation of the original opiate to provide more rapid onset of the active ingredient.

Pain Management of Patients with Substance Abuse in the Ambulatory Setting.

Abuse of illicit substances and prescription opioids is a growing problem that presents challenges for pain management in the inpatient and outpatient setting. With future patient care models shifting toward shorter hospital stays and more same-day surgeries, it is crucial that clinicians learn to manage this patient population and strike a balance between the overtreatment of pain that can subsequently worsen tolerance and addiction, and the undertreatment of pain that can lead to pseudoaddiction.

Acinetobacter: an underrated foodborne pathogen?

The increasing prevalence of foodborne diseases observed in developing countries has been linked to a rise in the consumption of raw foods. However, unlike the classical pathogens that are commonly implicated in foodborne illnesses, members of the genus Acinetobacter are rarely associated with diarrheal disease, probably because of the difficulty in isolating these Gram-negative bacteria from food sources. Nevertheless, several species of Acinetobacter, especially A. baumannii, possess many of the characteristics associated with successful pathogens and exhibit a prodigious ability to acquire the multiple-drug resistance (MDR) phenotype. In this mini-review, we summarize the epidemiological data relating to MDR Acinetobacter and consider evidence suggesting that contaminated dairy products, along with raw fruit and vegetables, constitute extra-hospital reservoirs of this underrated pathogen, and may represent an increased risk to immunocompromised individuals and young children in healthcare settings.

Antithyroid arthritis syndrome.

Antithyroid arthritis syndrome is a constellation of symptoms of myalgia, arthralgia, arthritis, fever and rash associated with the use of antithyroid medications. We report a case of a patient with severe hyperthyroidism likely secondary to Graves' disease who presented with the abovementioned symptoms after being treated with methimazole (antithyroid medication). Our aim is to increase awareness regarding this uncommon but disabilitating and life-threatening adverse effect of antithyroid medications among clinicians. We also discuss the proposed pathophysiology for this immunological reaction as well as management options in these patients.

Comparative pharmacokinetics of bergenin, a main active constituent of Saxifraga stolonifera Curt., in normal and hepatic injury rats after oral administration.

Bergenin, isolated from the herb of Saxifrage stolonifera Curt. (Hu-Er-Cao) has hepatoprotective, anti-inflammatory, antitussive, and neuroprotective activities. The aim of the present study was to establish a simple, rapid, and sensitive RP-HPLC method for determination of bergenin in rat plasma and compare its oral pharmacokinetic behaviors in normal and CCl4-induced hepatic injury rats. With norisoboldine as an internal standard, chromatographic separation was performed on a C18 analytical column with acetonitrile and water (11 : 89, V/V) containing 0.1% formic acid as the mobile phase. A good linearity was obtained over the range of 100-10 000 ng·mL(-1). The lower limit of quantification was 50 ng·mL(-1). The developed method was successfully applied to a study of the pharmacokinetic difference of bergenin (100 mg·kg(-1)) between normal and hepatic injury rats after oral administration. Marked alterations of pharmacokinetic parameters in hepatic injury rats were observed. Compared to normal rats, the AUC(0-∞) of bergenin in hepatic injury rats was elevated to 2.11-fold and Cmax was increased by 130%, whereas CL value was only 55% of the normal rats, suggesting that the systemic exposure of bergenin was significantly increased under hepatic injury status.

Dual drainage using a percutaneous pancreatic duct technique contributed to resolution of severe acute pancreatitis.

A 66-year-old man was admitted for severe acute alcoholic pancreatitis with infected pancreatic necrosis (IPN). Abdominal computed tomography revealed an inflamed pancreatic head, a dilated main pancreatic duct (MPD), and a large cavity with heterogeneous fluid containing gas adjacent to the pancreatic head, and extending to the pelvis. The cavity was drained percutaneously near the pancreatic head on admission; another tube was inserted into the pelvic cavity on hospital day 3. The drained fluid contained pus with high amylase concentration. Nasopancreatic drainage tube placement was unsuccessfully attempted on hospital day 9. On hospital day 23, percutaneous puncture of the MPD and placement of a pancreatic duct drainage tube was performed. Pancreatography revealed major extravasation from the pancreatic head. The IPN cavity receded; the percutaneous IPN drainage tube was removed on hospital day 58. On hospital day 83, the pancreatic drainage was changed to a transpapillary pancreatic stent, and the patient was discharged. Measuring the amylase concentration of peripancreatic fluid collections can aid in the diagnosis of pancreatic duct disruption; moreover, dual percutaneous necrotic cavity drainage plus pancreatic duct drainage may be essential for treating IPN. If transpapillary drainage tube placement is difficult, percutaneous pancreatic duct drainage may be feasible.
