Arsenic toxicity following Ayurvedic medication

Alternative forms of medicine like Ayurveda have witnessed a rise in global popularity over the recent decades. Drugs used in Ayurveda, particularly those of mineral origin can lead to toxic effects due to heavy metal overdose. Here, we report the case of a 53-year-old woman who presented with glove-and-stocking paresthesia and scaly plaques following the institution of Ayurvedic drugs containing arsenic for dermatitis. She also had a loss of distal proprioception and a hyperesthetic response to pinprick. Her blood analysis showed elevated arsenic levels; 12 times the acceptable upper limit, with normal lead, cadmium, mercury, and chromium levels. The drug was immediately stopped and there was a gradual but incomplete resolution of the paresthesia and distal weakness over the next several months. The risk of heavy metal toxicity should be briefed to the patient before the start of mineral Ayurvedic drugs. Monitoring serum levels while on these medications might help identify toxicities early and can result in the commencement of therapy at an early stage

Lead-induced peripheral neuropathy following ayurvedic medication.

Lead poisoning following intake of Ayurvedic medication is one of the recent areas of concern. We report a case of a 58-year-old type II diabetic man who was stable with diet control and 30 mg pioglitazone per day. He took Ayurvedic medication for generalized weakness and developed peripheral neuropathy following its intake. He was found to have high blood and urinary lead levels and was diagnosed to have subacute lead poisoning. He was treated with d-Penicillamine for 8 weeks, following which his lead levels became normal. The use of d-Penicillamine was proved highly effective in treating a case of lead poisoning.

Evaluation of lung infiltration score to predict postural hypoxemia in ventilated acute respiratory distress syndrome patients and the lateralization of skin pressure sore.

Context: Mechanical ventilation with positive end expiratory pressure (PEEP) is associated with unequal aeration of lungs in acute respiratory distress syndrome (ARDS) patients. Therefore, patients may develop asymmetric atelectasis and postural hypoxemia during lateral positioning. Aims: To validate proposed lung infiltration score (LIS) based on chest x-ray to predict postural hypoxemia and lateralization of skin sores in ARDS patients. Settings and Design: University hospital ICU. Prospective, observational study of consecutive patients. Materials and Methods: Sixteen adult patients of both genders on mechanical ventilation with PEEP for 24 to <48 hours. On chest x-ray, 6 segments were identified on each lung. The proposed LIS points (0- normal; 1- patchy infiltrates; 2- white infiltrates matching heart shadow) were assigned to each segment. Without changing ventilation parameters, supine, left and right lateral positions at 45° tilt were randomly changed. At the end of 20 minutes of ventilation in each position, we observed arterial oxygen saturation, hemodynamic and arterial blood gases. Later, position change protocol (4 hourly) was practiced in ICU, and skin pressure sore grading was noted within a week of ICU stay. Statistical Analysis Used: Nonparametric Bland and Altman correlation analysis, ANOVA and Student t test. Results: Arterial oxygenation (PaO 2 /FiO 2 = 313± 145.6) was significantly (P<0.01) higher in better lung (lower LIS)-down position than supine (PaO 2 /FiO 2 = 199± 70.2) or a better lung-up position (PaO 2 /FiO 2 = 165± 64.8). The positioning-related arterial oxygenation was significant (P< 0.05) at LIS asymmetry ≥3 between two lungs. Conclusions: The LIS mapping on chest x-ray was useful to differentiate between asymmetric lung disease and postural hypoxemia in ICU patients, which predisposed patients to early skin sore changes on higher LIS side.
