'Bastard bush': acacia thorn injuries and management.

This case report outlines the presentation and management of a young soldier who sustained a lower limb acacia thorn injury while on exercise in Kenya. The injury failed to heal with a subsequent ultrasound scan revealing a large retained thorn requiring surgical removal and wash out. From this case, lessons can be learnt regarding the management of thorn injuries, which are common in exercising troops in Kenya and indeed around the world. The key take-home messages are always consider a retained thorn if wounds fail to settle, use ultrasound as the imaging modality of choice, always remove identified retained thorns and if antibiotics are required use broad-spectrum antibiotics pending culture results.

Retroperitoneal Abscess Associated With a Migrating Grass Awn in a Cat: Treatment With Omentalization and Grass Awn Removal.

An 18-month-old domestic short hair male castrated cat presented with a history of fever of unknown origin of 1-year duration. Abdominal ultrasound revealed a mixed echogenicity mass. Cytological examination of the fluid obtained through fine needle aspiration was consistent with a retroperitoneal abscess. The cat underwent a midline celiotomy and the abscess was opened, lavaged, and omentalized. Antibiotics were also administered. Two months after surgery, the cat represented with a fluctuant swelling in the right flank region at the lumbodorsal triangle. Abdominal and mass ultrasound showed a mixed echogenicity swelling in the right flank. Under gas anesthesia, the swelling was surgically explored and a 0.4 cm long grass awn was found and removed. Telephone communication with the owners 6 months after surgery found the cat to be free of clinical signs.

Penetrating palpebral grass awn in a dog: Unusual case of a penetrating grass awn in an eyelid.

An unusual case of a penetrating grass awn in an eyelid of a dog is reported. A 6-month-old mixed breed dog was referred to the Ophthalmology Unit of the Veterinary Teaching Hospital of Camerino University for anorexia, lethargy, left monolateral ocular swelling and pain to the left eye, present from 1 month. Ophthalmic examination of the left eye showed copious and purulent discharge, and ultrasonography revealed the presence of an abscess containing a grass foreign body. The grass awn was surgically removed. Three days after surgery, the dog showed a marked improvement, with a total resolution obtained in 7 days. To the authors' knowledge, penetrating foreign bodies such as the one of this paper have never been described before in literature.

A Test-Retest Reliability Study of Human Experimental Models of Histaminergic and Non-histaminergic Itch.

Numerous exploratory, proof-of-concept and interventional studies have used histaminergic and non-histaminergic human models of itch. However, no reliability studies for such surrogate models have been conducted. This study investigated the test-retest reliability for the response to histamine- and cowhage- (5, 15, 25 spiculae) induced itch in healthy volunteers. Cowhage spiculae were individually applied with tweezers and 1% histamine was applied with a skin prick test (SPT) lancet, both on the volar forearm. The intensity of itch was recorded on a visual analogue scale and self-reported area of itch was assessed 5 and 10 min after itch provocation. Reliability of the evoked itch (area under the curve and peak intensity) was assessed by the coefficient of variation (CV), intra-class correlation coefficient (ICC), and sample size estimation for parallel and cross-over designs. Cowhage (ICC = 0.57-0.77, CVbetween = 97%, CVwithin = 41%) and histamine: (ICC = 0.83-0.93, CVbetween = 97%, CVwithin = 20%) exhibited moderate-to-excellent intra-individual reliability and moderate inter-individual reliability for the itch intensity. For a test-retest observation period of one week, SPT-delivered histamine and application of cowhage-spiculae are reproducible human models of itch. The high inter-individual and low intra-individual variability suggests cross-over designed studies when applicable.

Cowpea (Vigna unguiculata L. Walp), a renewed multipurpose crop for a more sustainable agri-food system: nutritional advantages and constraints.

The growing awareness of the relevance of food composition for human health has increased the interest of the inclusion of high proportions of fruits and vegetables in diets. To reach the objective of more balanced diets, an increased consumption of legumes, which constitutes a sustainable source of essential nutrients, particularly low-cost protein, is of special relevance. However, the consumption of legumes also entails some constraints that need to be addressed to avoid a deleterious impact on consumers' wellbeing and health. The value of legumes as a source of nutrients depends on a plethora of factors, including genetic characteristics, agro-climatic conditions, and postharvest management that modulate the dietary effect of edible seeds and vegetative material. Thus, more comprehensive information regarding composition, especially their nutritional and anti-nutritional compounds, digestibility, and alternative processing procedures is essential. These were the challenges to write this review, which focusses on the nutritional and anti-nutritional composition of Vigna unguiculata L. Walp, an emerging crop all over the world intended to provide a rational support for the development of valuable foods and feeds of increased commercial value. © 2016 Society of Chemical Industry.

Presentation of three cases with phyto contact dermatitis caused by Ranunculus and Anthemis genera.

In addition to being used especially in a systematic way, herbal treatments are preferred topically by the elderly population in some rheumatological and dermatological diseases. Although alternative medicine treatments may have beneficial effects, certain plants are known to cause common contact dermatitis. Protoanemonin and sesquiterpene lactones, which are found in such plant types as respectively Ranunculus and Anthemis, often cause contact dermatitis. In this article, three cases of phyto contact dermatitis, which are the result of topical use of plant types of Ranunculus ve Anthemis as an alternative method of treatment due to myalgia or arthralgia, have been presented.

Condensed tannin accumulation and nitrogen fixation potential of Onobrychis viciifolia Scop. grown in a Mediterranean environment.

BACKGROUND: Sainfoin (Onobrychis viciifolia Scop.) is a forage legume found in temperate areas but is less widespread in Mediterranean environments. Compared with other perennial legumes, it has the advantage of containing condensed tannins (CT) that can be important for their implications on ruminant nutrition and health. Data on nitrogen (N) fixation by sainfoin in the literature originate from very different environments and only a few field data are available, so it is important to improve knowledge on the N fixation potential of this species, particularly under a Mediterranean climate. Here the accumulation pattern of polyphenolic compounds (total, non-tannic polyphenols and CT) and the N fixation potential of sainfoin were studied in order to contribute to its valorisation for sustainable farming management in Mediterranean environments. RESULTS: CT concentrations were always in the range considered beneficial for animals, not exceeding 50 g delphinidin equivalent kg⁻¹ dry matter (DM). The regression of aerial fixed N on aerial DM showed a relationship of 22 kg fixed N t⁻¹ aerial DM in a Mediterranean environment. CONCLUSION: A wider exploitation of sainfoin is suggested for production under rain-fed conditions, thus enlarging the limited set of available perennial legumes suitable for Mediterranean environments.

Cheilitis granulomatosa associated with allergic contact dermatitis to betel quid.

Cheilitis granulomatosa (CG) is a rare disorder of unknown origin, which is characterized clinically by painless, recurrent or persistent swelling of 1 or both lips. Betel quids, composed of betel nuts (seeds of the Areca catechu), slake lime, and Piper betel leaf/or Piper betel inflorescence, are widely used in Asia and strongly associated with oral mucosal disease. It has also been found to be a cause of contact leukomelanosis because of its ingredients of various chemicals. We describe a case of CG induced by betel quid chewing.

Thorn prick osteomyelitis of the foot in barefoot walkers: a report of four cases.

Walking barefoot is common in developing countries and the feet are therefore exposed to a variety of trivial injuries, some of which lead to cellulitis or abscess formation. If left untreated or improperly managed, osteomyelitis or septic arthritis, usually involving the heel or metatarsals, may follow. In countries with limited resources, the emphasis should be on clinical assessment for diagnosis, and good surgical technique for treatment. We report 4 patients with thorn prick osteomyelitis of the foot due to walking barefoot. All were treated with thorn removal, surgical debridement, and oral ofloxacin. Surgical removal of the thorn is the key to successful treatment and to avoiding recurrent infection.

Primula obconica--is contact allergy on the decline?

Primula obconica, a member of the Primulaceae family, was introduced to Britain from China in 1880. P. obconica cultivars, which are reputed to contain less primin, have been developed over the past number of years in an attempt to reduce the incidence of allergic contact dermatitis. Primin (2-methoxy-6-pentyl-1,4-benzoquinone) is the main sensitizer, although other allergens have been postulated. We believe the incidence of primula allergic contact dermatitis has fallen since the introduction of primin-free P. obconica into the European market and thus the aims of this study were twofold. First, to determine whether the incidence of primula allergic contact dermatitis was truly on the decline and, second, to confirm the presence of primin-free P. obconica in the UK. We surveyed the incidence of primula allergic contact dermatitis in the UK and compared the incidence in the period between 1995 and 2000 with a subsequent follow-up study looking at the incidence for 2002. The results showed a significant fall in primin-positive patch tests from 1995 to 2000. The follow-up results for 2002 showed a further reduction in the number of primin-positive patch tests. The yearly incidence of contact allergy to primin has fallen from 0.785% in 1995/1996 to 0.429% in 2002. This downward trend was statistically significant (P = 0.001). A telephone survey of UK seed suppliers and selected plant retailers was also undertaken to clarify what types of P. obconica were available for sale and to assess suppliers' and retailers' knowledge of the primin-free varieties. This survey showed that 50% of suppliers were selling primin-free varieties but that the majority of surveyed retailers were not currently selling any variety of P. obconica. Our study suggests that although the yearly incidence of contact allergy to primin has fallen significantly over the past 8 years, it is still an important allergen, and thus its inclusion in the standard series remains justified for the foreseeable future.
