Paclitaxel is used for the treatment of several types of cancers. However, one of the significant limiting complications of paclitaxel is painful peripheral neuropathy during its therapy. In this study we examined the engagement of antioxidative signal pathway of the dorsal root ganglion (DRG) in mechanical and thermal hypersensitivity evoked by paclitaxel. Behavioral test was performed to determine mechanical and thermal sensitivity in rats. Western Blot analysis and ELISA were used to examine expression of Nrf2-antioxidant response element (ARE) and superoxide dismutases (SOD); and the levels of products of oxidative stress in the DRG...

Juvenile arthritis with unknown disease etiology is also known as juvenile idiopathic arthritis. Symptoms include joint pain, swelling, and stiffness, and standard treatment involves immunosuppressant medication. Here we present a case of juvenile idiopathic arthritis with severe malnutrition and worsening of symptoms, which restrained a nine-year-old girl to a wheelchair with minimal movement capacity and low energy during standard immunosuppressant therapies over the course of three years. Our innovative Pathogen Blood Test combining cytology-based microscopy and genetic analysis using a pan-fungal primer assay and sequencing identified a systemic fungal infection with Sagenomella species, closely related to Aspergillus , and a soil-dwelling highly pathogenic fungus, which had previously been linked to a fatal veterinary case of arthritis and malnutrition...

Scurvy is a disease that is rarely encountered in modern medicine. A condition that was classically associated with sailors, its incidence has decreased dramatically since the discovery of its association with vitamin C deficiency. We present the case of a 2-year-old boy, whose treatment for neuroblastoma was complicated by gastrointestinal disease, which necessitated enteral feeding. While still undergoing treatment, he started to complain about increasing pain in his lower limbs, which appeared to be markedly tender on palpation...

BACKGROUND: Post-operative pain may adversely affect a patient's quality of life. Studies have shown that vitamin C, being an anti-oxidant and neuro-modulating agent, can help to reduce pain in a variety of clinical settings. The objective of this randomized controlled trial was to assess the effectiveness of vitamin C in reducing post-operative pain, analgesia requirements and improving functional outcome. METHODS: Patients with isolated foot and ankle trauma, who had undergone surgery, were randomly assigned to receive either vitamin C 500mg or a placebo tablet twice a day...

Glyceryl trinitrate (GTN) has found widespread use for the treatment of angina pectoris, a pathological condition manifested by chest pain resulting from insufficient blood supply to the heart. Metabolic conversion of GTN, a nitric oxide (NO) pro-drug, into NO induces vasodilation and improves blood flow. Patients develop tolerance to GTN after several weeks of continuous use, limiting the potential for long-term therapy. The mechanistic cause of nitrate tolerance is relatively unknown. We developed a cell culture model of nitrate tolerance that utilizes stable isotopes to measure metabolism of 15 N3 -GTN into 15 N-nitrite...

Wound healing can be a painful and time-consuming process in patients with diabetes mellitus. In light of this, the use of wound healing devices could help to accelerate this process. Here, cellulose-based films loaded with vitamin C (VitC) and/or propolis (Prop), two natural compounds with attractive properties were engineered. The starting materials and the cellulose-based films were characterized in detail. As assessed, vitamin C can be released from the Cel-PVA/VitC and Cel-PVA/VitC/Prop films in a controlled manner...

BACKGROUND: In March and April 2018, more than 150 patients presented to hospitals in Illinois with coagulopathy and bleeding diathesis. Area physicians and public health organizations identified an association between coagulopathy and synthetic cannabinoid use. Preliminary tests of patient serum samples and drug samples revealed that brodifacoum, an anticoagulant, was the likely adulterant. METHODS: We reviewed physician-reported data from patients admitted to Saint Francis Medical Center in Peoria, Illinois, between March 28 and April 21, 2018, and included in a case series adult patients who met the criteria used to diagnose synthetic cannabinoid-associated coagulopathy...

A 69-year-old man presented with unilateral calf pain, swelling, and erythematous rash. He was initially treated with antibiotics for suspected cellulitis. A venous duplex ultrasound, performed to exclude deep venous thrombosis, revealed multiple heterogeneous hypoechoic foci of unknown etiology throughout the calf musculature. His condition did not improve with antibiotics, instead progressing to a necrotic ulcer along the medial malleolus. Clinical suspicion of vascular insufficiency or vasculitis prompted an extensive imaging work-up...

Pain is an unpleasant subjective feeling having implications on both physical and mental realm. Multiple dimensions of pain involving behavioral, spiritual, emotional, and cognitive changes have been studied and pathways elucidated. It is stressed that the nature in which pain is modulated and perceived at a higher center is a complex phenomenon. One of the main goals of pain modulation is to modify pain to a more tolerable level, rather than its complete eradication. Different pain management interventions were tried but have effects that are more adverse...

Sickle cell disease (SCD) and vitamin D deficiency share manifestations such as bone complications and bony pains. Canadian SCD children are characterized by compromised sun exposure all year long and potential dietary deficiency, which combined to SCD-causing high nutritional demands, may lead to impaired vitamin D status. The objectives of this study were to document vitamin D status and intake and assess the relationship between vitamin D status and SCD-related outcomes in Canadian children with SCD followed in a tertiary pediatric center...

Denosumab, a novel agent that inhibits osteoclasts, reduces the risk of fracture in patients with osteoporosis. However, worsening of hypophosphatemia and other symptoms may be induced by denosumab in patients with pre-existing hypophosphatemic osteomalacia. A 58-year-old man with hepatitis B presented with diffuse bone pain and muscle weakness. Denosumab was prescribed by the orthopedist according to documented low bone mass and spine compression fracture. After administering denosumab, the patient's bone pain worsened, and he later developed a right tibia stress fracture...

Citric acid naturally exists in fruits and vegetables. However, it is not the naturally occurring citric acid, but the manufactured citric acid (MCA) that is used extensively as a food and beverage additive. Approximately 99% of the world's production of MCA is carried out using the fungus Aspergillus niger since 1919. Aspergilus niger is a known allergen. The FDA placed MCA under the category of GRAS without any research to substantiate this claim. In 2016, 2.3 million tons of MCA were produced, predominantly in China, and approximately 70% is used as a food or beverage additive...

We report three cases of scurvy in previously healthy children referred to us for leg pain and refusal to walk. All children had no significant medical history, symptoms had started months before and subtly advanced. Two of them presented with gingival hyperplasia and petechiae, another one reported night sweats and gingival bleeding in the past few weeks. Two had vitamin D deficiency, and all had microcytic anaemia (in one case requiring transfusional support). A nutritional screening revealed low or undetectable levels of ascorbic acid...
