REVIEW
J M Chatkin, L Zani-Silva, I Ferreira, N Zamel
Inhalation of cannabis smoke is its most common use and the pulmonary complications of its use may be the single most common form of drug-induced pulmonary disease worldwide. However, the role of cannabis consumption in asthma patients and allergic clinical situations still remains controversial. To review the evidence of asthma and allergic diseases associated with the use of marijuana, we conducted a search of English, Spanish, and Portuguese medical using the search terms asthma, allergy, marijuana, marihuana, and cannabis...

Usher syndrome (USH) is a rare autosomal recessive disease and the most common inherited form of combined visual and hearing impairment. Up to 13 genes are associated with this disorder, with USH2A being the most prevalent, due partially to the recurrence rate of the c.2299delG mutation. Excluding hearing aids or cochlear implants for hearing impairment, there are no medical solutions available to treat USH patients. The repair of specific mutations by gene editing is, therefore, an interesting strategy that can be explored using the CRISPR/Cas9 system...

The 2013 American Heart Association Blood Cholesterol Guidelines increased the number of patients recommended for statin therapy in the United States to 56million. Two common statin side effects are muscle pain, referred to as "statin-associated muscle symptoms", and increased risk for new onset type-2-diabetes mellitus. Up to 25% of statin users report muscle symptoms resulting in many patients being switched to lower dose or lower potency statins, or refusing statins altogether. The most likely signaling mechanisms for statin-associated muscle symptoms overlaps with the proposed mechanism of statin-induced insulin resistance...

There are no effective medications for delaying the progress of Alzheimer's disease (AD), the most common neurodegenerative disease in the world. In this study, our results with C. elegans showed that rose essential oil (REO) significantly inhibited AD-like symptoms of worm paralysis and hypersensivity to exogenous 5-HT in a dose-dependent manner. Its main components of β-citronellol and geraniol acted less effectively than the oil itself. REO significantly suppressed Aβ deposits and reduced the Aβ oligomers to alleviate the toxicity induced by Aβ over-expression...

K Krüger
The perioperative management of patients on immunosuppressive drugs is uncertain due to a lack of controlled studies. Continuation of medication without a pause may increase the risk of postoperative infections and wound healing disorders and when the pause is too long this can induce a flare of the underlying rheumatic disease. Additional factors, such as rheumatic disease activity, comorbidities, previous infections and the type of surgical procedure also modulate the risk. The highest risk of infection is associated with corticosteroids depending on the dose, so that a dosage as low as possible but stable in the perioperative period is recommended...

BACKGROUND: Drug-induced immune hemolytic anemia (DIIHA) and drug-induced immune thrombocytopenia (DIIT) are rare but dangerous complications of pharmacotherapy that may be underrecognized in hematopoietic stem cell transplant (HSCT) patients due to overlap of signs and symptoms with those of more common disease processes. CASE REPORT: A 61-year-old woman with NK-cell deficiency and GATA-2-associated myelodysplastic syndrome, status post-recent allogeneic HSCT (Day +58), presented with 3 days of acute-onset severe back pain, muscle cramps, and increasingly dark urine...

The treatment of motor manifestations of Parkinson's disease (PD) is essentially a trade-off between adequate relief of motor symptoms and prevention and control of motor complications, particularly levodopa-induced dyskinesia (LID). Progression of PD is paralleled by a progressive difficulty in achieving the balance. Functional neurosurgical procedures provide sustained relief of LID in carefully selected patients when further tailoring of medical therapy fails to achieve this goal. Though deep brain stimulation (DBS) has superseded lesioning surgeries, pallidotomy still has a role in those patients in whom DBS is not feasible for financial or other reasons...

Levodopa-induced dyskinesia (LID) is commonly seen in Parkinson's disease patients treated with levodopa. This side effect is usually encountered after long duration of treatment, but occasionally, this may be seen even after few days or months of treatment. LID is broadly classified as peak-dose dyskinesia, wearing-off or off-period dyskinesia, and diphasic dyskinesia. Pathogenesis of LID is complex, and different neurotransmitters such as dopamine, glutamine, adenosine, and gamma-aminobutyric acid play important role altering the normal physiology of direct and indirect pathway of cortico-basal ganglia-thalamic loop responsible for fine motor control...

Obstructive lung diseases are common causes of disability and death worldwide. A hallmark feature is aberrant activation of Gq protein-dependent signaling cascades. Currently, drugs targeting single G protein (heterotrimeric guanine nucleotide-binding protein)-coupled receptors (GPCRs) are used to reduce airway tone. However, therapeutic efficacy is often limited, because various GPCRs contribute to bronchoconstriction, and chronic exposure to receptor-activating medications results in desensitization. We therefore hypothesized that pharmacological Gq inhibition could serve as a central mechanism to achieve efficient therapeutic bronchorelaxation...

Acute liver failure (ALF) is an acute medical emergency which carries high mortality without liver transplantation. Various hepatotropic viruses, drug induced liver injury, auto immune hepatitis, and metabolic liver diseases are the commonly implicated etiologic agents. Liver involvement in dengue hemorrhagic fever (DHF) is quite common, but acute liver failure is its rare complication. Neurological complications are also commonly seen in DHF. Ateenage girl presented with high grade fever and subconjunctival hemorrhage, and later developed jaundice due to acute liver failure...

Pasireotide is a somatostatin analog (SSA) that targets somatostatin receptor subtype 1 (SST1), SST2, SST3, and SST5 with a high affinity. Pasireotide has a better antisecretory effect in acromegaly, Cushing's disease, and neuroendocrine tumors than octreotide. In this study, we compared the effects of pasireotide to those of octreotide in vitro on meningioma primary cell cultures, both alone and in combination with the mTOR inhibitor everolimus. Significant mRNA expression levels of SST1, SST2, and SST5 were observed in 40...

This article reviews recent advances in the research of the mechanisms of bone loss, as well as clinical features, economic impact and therapeutic implications of osteoporosis and fractures in patients with systemic lupus erythematosus (SLE) as an illustration of bone disease in a complex systemic autoimmune connective tissue disease. Recent studies demonstrated an increased incidence of osteoporosis and peripheral and vertebral fractures in patients with SLE. The aetiology of bone loss in SLE is multifactorial, including clinical osteoporosis risk factors, systemic inflammation, serological factors, metabolic factors, hormonal factors, possibly genetic factors and medication-induced adverse effects...

BACKGROUND: Cachectic patients with chronic obstructive pulmonary disease (COPD) may benefit from nutritional support. This double-blind, randomized, controlled trial evaluated the safety and efficacy of targeted medical nutrition (TMN) vs. an isocaloric comparator in pre-cachectic and cachectic patients with COPD. METHODS: Patients aged ≥50 years with moderate-to-severe COPD and involuntary weight loss or low body mass index (16-18 kg/m(2) ) were randomized 1:1 to receive TMN (~230 kcal; 2 g omega-3 fatty acids; 10 μg 25-hydroxy-vitamin D3) or isocaloric comparator twice daily for 12 weeks (ClinicalTrials...

Loeffler endocarditis is a rare restrictive cardiomyopathy caused by abnormal endomyocardial infiltration of eosinophils, with subsequent tissue damage from degranulation, eventually leading to fibrosis. Although an uncommon entity, it is still a disease with significant morbidity and mortality. Often identified only at late stages, treatment options are limited once fibrosis occurs, usually requiring heart failure medications or surgical intervention. We present a unique case of a woman with remote history of hypereosinophilic syndrome, attributed to treatment of rheumatoid arthritis with infliximab, who presented with symptoms of heart failure refractory to medical management and was found to have Loeffler endocarditis...

BACKGROUND: Thoracic endovascular aortic repair (TEVAR) has become lately the procedure of choice in the treatment of most pathologies of descending thoracic aorta. Aortic arch aneurysms also came to be treated by TEVAR with various hybrid techniques or custom made scalloped/fenestrated stent-grafts. Zone 0; ascending TEVAR is more challenging than TEVAR of the descending thoracic aorta or aortic arch because of the more complex pathology, hemodynamics, and anatomy. Ascending TEVAR can be a lifesaving treatment in selected high surgical risk patients...

BACKGROUND: In Ethiopia, 20,000 women die each year from complications related to pregnancy, childbirth and post-partum. For every woman that dies, 20 more experience injury, infection, disease, or disability. "Maternal near miss" (MNM), defined by the World Health Organization (WHO) as a woman who nearly dies, but survives a complication during pregnancy, childbirth or within 42 days of a termination, is a proxy indicator of maternal mortality and quality of obstetric care. In Ethiopia, few studies have examined MNM...
