Recurrent Anaphylaxis with Watermelon and Pumpkin Seeds in a Boy Tolerant to Their Pulps.

Background: Seeds are widely consumed as a traditional snack and have rich contents beneficial to health. With an increase in consumption rates, allergic reactions occur more frequently. We focus on multiple seed consumption related to recurrent anaphylaxis in this case. Case Presentation: We evaluated an 11-year-old boy with recurrent anaphylaxis. According to his medical records, he had been hospitalized several times, diagnosed with anaphylaxis, and treated. The family noticed direct (eating) or indirect contact with pumpkin seeds. In addition, the family mentioned another anaphylactic episode after watermelon seed and poppy seed bread consumption. We conducted skin prick-to-prick tests, examined total immunoglobulin E levels, and prescribed the treatment with an adrenalin autoinjector and preventive dietary recommendations. Conclusion: Anaphylaxis, particularly recurrent ones, should be evaluated with detailed anamnesis and supported with laboratory tests. Although seeds are beneficial and highly nutritious, it is necessary to consider them a source of allergens.

Determination of cyanide in whole seeds and brans of linseed (Linum usitatissimum Linn) by molecular spectrophotometry

Abstract The addition of linseed (Linum usitatissimum Linn) in the diet, as a functional food, has increased over the years. However, it possesses cyanogenic glycosides. This study aimed to quantify and compare cyanide concentration in whole seed and bran of brown and golden types to establish a safe limit of intake. Three commercial labels, from brown and golden whole seed types (Ab, Ag, Bb, Bg, Cb and Cg), and six commercial labels of brown and golden bran (1b, 2g, 3g, 4b, 5g, and 6b), were selected, totalizing twelve samples. Total cyanide concentration was quantified by a colorimetric method employing alkaline picrate, after acid hydrolysis. The whole seed cyanide values were between 348.4 and 473.20 µg/g and the bran cyanide values were between 459.53 and 639.35 µg/g. The analyzed bran presented increased cyanide concentrations than the whole seeds with no differences between brown and golden types. Food able to produce cyanide less than 90 µg/kg body weight, daily, is considered secure for consumption. Considering this limit and analyzed samples, it is safe to eat approximately two tablespoons of seeds or one tablespoon of bran. These results point out the importance of cyanide amount daily intake information to be in linseed packaging, to ensure secure consumption

Biliary obstruction caused by plant seeds.

Biliary obstruction is rarely caused by foreign objects; therefore, the precise diagnosis may be challenging. Even in rare situations, cases of biliary obstruction caused by plant seeds have not been reported previously. To our knowledge, herein, we report the first case of biliary obstruction caused by accumulated plant seeds forming a solid mass with inflammatory cells and bile juice, which were identified as Solanum lycopersicum, Brassica, and Citrus species by DNA analysis and pathological assessment of the specimen after surgical resection for biliary obstruction suggestive of cholangiocarcinoma.

Recent advances in the diagnosis and management of tree nut and seed allergy.

PURPOSE OF REVIEW: Tree nut (TN) and seed allergies are frequent, and their prevalence appears to be on the rise. Allergic reactions associated with these foods are more frequently severe, and these allergies tend to persist into adulthood, consequently affecting quality of life. In this review, we summarize recent advances in diagnostic modalities and management strategies for TN/seed-allergic patients. RECENT FINDINGS: Clinical manifestations of TN and seed allergy range from asymptomatic sensitization to severe anaphylactic reactions. The use of emerging diagnostic tools such as component resolved diagnostics (CRD) and the basophil activation test (BAT) can help better predict clinical reactivity, the latter being currently reserved for research settings. Strict avoidance of all TN is generally not required, as most patients can tolerate select TN despite co-sensitization. Oral immunotherapy (OIT) is a promising alternative treatment instead of complete avoidance of culprit allergens, as it can safely increase the allergy threshold. SUMMARY: Our recent understanding of co-reactivity between various TN and seeds has shaped management opportunities, including select TN introduction and optimization of OIT, two strategies which may improve quality of life. There is a need for better minimally invasive diagnostic methods for TN and seed allergy, with CRD and BAT being promising tools.

The benefit of Silybum marianum in ethanol-induced reprotoxicity of male Wistar rat

Abstract This study investigates the toxic effects of ethanol (Eth) on the reproductive system of male rats and the possible protective role of Silybum marianum seeds-infused solution (SMI) over six consecutive weeks of administration. Animals were divided into the following groups: control, SMI positive control (200 mg/kg/day), Eth1 (1 g/kg/day), Eth2 (2 g/kg/day), Eth1+SMI, and Eth2+SMI. Plasma testosterone concentration, epididymal spermatozoa biology, and testicular and epididymal MDA, GSH and GPx levels were evaluated. The results indicated a significant decrease in testis and epididymis weight, testosterone level, sperm concentration, sperm vitality and sperm motility (total motility, progressive motility, curvilinear velocity, straight-line velocity, velocity average path, beat cross frequency, and lateral head displacement) in both Eth1 and Eth2 compared to the control groups and the combined-treatment groups (Eth1+SMI and Eth2+SMI). Furthermore, results showed a significant elevation in MDA concentration with a significant decrease of testicular and epididymal GSH concentration and GPx activity in theEth1 and Eth2 groups compared to the combined-treatment groups. The administration of SMI succeeded in improving the parameters cited above in the combined-treatment groups compared to the Eth1 and Eth2 groups, and bring them to the levels seen in the control groups. To conclude, SMI has clearly protected reproductive indices against ethanol-induced reprotoxicity in male rats

Edible Plant Sprouts: Health Benefits, Trends, and Opportunities for Novel Exploration.

The consumption of plant sprouts as part of human day-to-day diets is gradually increasing, and their health benefit is attracting interest across multiple disciplines. The purpose of this review was to (a) critically evaluate the phytochemicals in selected sprouts (alfalfa, buckwheat, broccoli, and red cabbage), (b) describe the health benefits of sprouts, (c) assess the recent advances in sprout production, (d) rigorously evaluate their safety, and (e) suggest directions that merit special consideration for further novel research on sprouts. Young shoots are characterized by high levels of health-benefitting phytochemicals. Their utility as functional ingredients have been extensively described. Tremendous advances in the production and safety of sprouts have been made over the recent past and numerous reports have appeared in mainstream scientific journals describing their nutritional and medicinal properties. However, subjects such as application of sprouted seed flours in processed products, utilizing sprouts as leads in the synthesis of nanoparticles, and assessing the dynamics of a relationship between sprouts and gut health require special attention for future clinical exploration. Sprouting is an effective strategy allowing manipulation of phytochemicals in seeds to improve their health benefits.

Safety Assessment of Citrus Plant- and Seed-Derived Ingredients as Used in Cosmetics.

The Expert Panel for Cosmetic Ingredient Safety (Panel) assessed the safety of 30 Citrus plant- and seed-derived ingredients, which are most frequently reported to function in cosmetics as fragrances and/or skin conditioning agents. Because final product formulations may contain multiple botanicals, each containing similar constituents of concern, formulators are advised to be aware of these constituents and to avoid reaching levels that may be hazardous to consumers. With Citrus plant- and seed-derived ingredients, the Panel was concerned about the presence of the hydroperoxides of limonene and linalool in cosmetics. Industry should use good manufacturing practices to limit impurities. The Panel reviewed the available data presented and concluded that 18 of these ingredients are safe in the present practices of use and concentration when formulated to be non-irritating and non-sensitizing. The data for the remaining 12 ingredients are insufficient to determine safety.

Antihypertensive and safety studies of Cydonia oblonga M.

Antihypertensive studies on aqueous-methanolic extract prepared from seeds of Cydonia oblonga M. were carried out. The test extract in 200, 400 and 600 mg/kg doses was investigated in normotensive, high cholesterol and glucose fed hypertensive rats through non-invasive blood pressure measuring technique. Acute and sub-chronic toxicity studies were conducted in mice and rats, respectively. The test extract significantly decreased dose dependently the systolic, diastolic and mean arterial pressures. The test extract in 600mg/kg dose produced maximum effect and prevented rise in blood pressure of high cholesterol diet and glucose fed rats as compare to control in 21 days studies. The extract was found safe up to 4g/kg dose in mice. In sub-chronic toxicity study, no significant alteration in blood chemistry of extract treated rats was observed except reduction in the low density cholesterol levels. It is concluded that Cydonia oblonga seeds extract possess antihypertensive effect which supports its use in folklore.

Diet-induced oxalate nephropathy from excessive nut and seed consumption.

Oxalate is a metabolite consumed in nuts, beans and leaves, and excreted in urine. Oxalosis can cause nephropathy. We describe a rare case of a high-oxalate diet intended for irritable bowel syndrome (IBS) treatment causing oxalate nephropathy. A 59-year-old woman with a history of controlled hypertension presented with creatinine 1.8 mg/dL, increased from baseline 1.3 mg/dL. She denied recent illness, urinary stones, medication adjustments, herbal supplements and non-steroidal anti-inflammatory drugs use. Diet included six tablespoons of chia seeds and five handfuls of almonds daily to manage IBS symptoms. Her electrolytes, urinalysis and renal ultrasound were unremarkable. Her 24-hour urine output revealed increased oxalate and low citrate. Renal biopsy showed glomerulosclerosis, fibrosis and calcium oxalate deposition. She switched to a low-oxalate diet, with improvement in laboratory markers. An earlier dietary history could have raised concern for oxalosis prior to renal biopsy. Providers should be trained to identify at-risk patients and provide appropriate dietary counselling.
