A new quarterly column debuts this month with a quick guide to the diagnosis and management of flea allergy dermatitis in general practice.

BACKGROUND: Simultaneous contact allergies to epoxy resins based on diglycidyl ether of bisphenol A (DGEBA-R) or epoxy resins of the bisphenol F-type and the reactive diluent phenyl glycidyl ether (PGE) have been reported. The reason might be cross-reactivity, exposure to an epoxy resin system with PGE as a component, or ...

Submergence-tolerant rice maintains viability during complete submergence by limiting underwater elongation until floodwaters recede. Acclimation responses to submergence are coordinated by the submergence-inducible Sub1A, which encodes an ethylene-responsive factor-type transcription factor (ERF). Sub1A is limited to tolerant genotypes and sufficient to confer submergence tolerance to intolerant accessions. Here we evaluated ...

Skin irritants may induce irritant contact dermatitis (ICD) in various ways but the end result remains the same: a clinical picture which in most cases is practically indistinguishable from allergic contact dermatitis (ACD). A treatment that works for ACD does not necessarily work for ICD. Management has to focus on ...

Curcuma xanthorrhiza Roxb. (Zingiberaceae) is a medicinal plant widely spread in South East Asia. In particular, it is commonly used not only for food and medicinal purposes in Indonesia, but also for the topical treatment of acne and skin inflammations as Thai traditional medicine. It was found that the methanol ...

Atopic dermatitis (AD) has many different clinical presentations. In our inner city practice, we have observed a variant of AD in our heavily pigmented patients that we have termed lichen planus-like atopic dermatitis because of its clinical similarity to lichen planus. Clinically, this variant may be distinguished by the presence ...

Common diaper dermatitis is an irritant contact diaper dermatitis (IDD) created by the combined influence of moisture, warmth, urine, feces, friction, and secondary infection. It is difficult to completely eradicate these predisposing factors in a diapered child. Thus, IDD presents an ongoing therapeutic challenge for parents, family physicians, pediatricians, and ...

The management of venous leg ulcers is frequently problematic, usually as a result of the patient's existing co-morbidities, but often because of problems in skin management, such as hyperkeratosis or skin sensitization and resulting contact dermatitis. Good leg ulcer management practice includes skin care, protection from excessive exudate and from ...

Tea tree oil is a popular ingredient in many over-the-counter healthcare and cosmetic products. With the explosion of the natural and alternative medicine industry, more and more people are using products containing tea tree oil. This article reviews basic information about tea tree oil and contact allergy, including sources of ...

BACKGROUND: Atopic dermatitis is a common condition, with a lifetime prevalence of approximately 10% to 20% among the Canadian population. A clear, practical, Canadian guideline for the management of these patients has been lacking. OBJECTIVE: To provide primary-care physicians, pediatricians and dermatologists with the first practical and comprehensive set of ...

BACKGROUND: Occupational contact dermatitis is a common condition often assumed to be 'part of the job'. OBJECTIVE: This article explores common causes of occupational contact dermatitis and details high risk occupations utilising local data. Tips for improved understanding and management of occupational contact dermatitis are also presented. DISCUSSION: General practitioners ...

The Saccharomyces cerevisiae branched-chain amino acid permease Bap2p plays a major role in leucine, isoleucine, and valine transport, and its synthesis is regulated transcriptionally. Bap2p undergoes a starvation-induced degradation depending upon ubiquitination and the functions of N- and C-terminal domains of Bap2p. Here we show that the N-terminal domain of ...

Photocontact dermatitis is not a common condition, but neither is it rare. Both photo-irritant contact dermatitis (PICD) and photoallergic contact dermatitis (PACD) are seen by most dermatologists in general practice. PICD is diagnosed on clinical grounds and is usually caused by furocoumarins in plants like limes and celery. PACD is ...

The management of atopic dermatitis is set for a major shift with the introduction of the first new topical treatment for the condition in 40 years--the non-steroidal topical immunomodulator tacrolimus (Protopic). Backed by strong clinical data, tacrolimus ointment is a valuable addition to topical steroids in the management of moderate-to-severe ...

Rigid lens fitting has been an integral part of contact lens practice for decades. However, rigid lens fitting has been constantly declining since soft lenses were introduced in the 1970s to whereby, world wide, rigid lenses constitute less than 10% of new contact lens fits. It seems that many practitioners ...

Ergonomics is now fairly routinely used in industry. Managers often initiate contact with ergonomists. The paper argues that many ergonomists have abandoned some fundamental ergonomics principles and have unwittingly succumbed to 'sitting complacently in the manager's toolbox'. It is also argued that through its inherent diversity, ergonomics is in danger ...

Ready to go to "cyberschool"? Here's practical advice on making it work for you.

Hairdressers belong to an occupational group that is commonly affected by occupational skin disease, specifically contact dermatitis, which may be allergic or irritant and, less commonly, contact urticaria. Occupational contact dermatitis predominantly affects apprentices, and atopy is a recognized risk factor associated with a poor prognosis. Repetitive wet work leading ...

Videokeratoscopy is an important addition to contact lens practice, where a better understanding of corneal contour obviously helps the practitioner to achieve an optimal fitting relationship between the contact lens and the cornea. A variety of topographical maps, encompassing a large range of corneal conditions, are presented in this study ...

Updating our clinical concept of atopic dermatitis (AD) evolves from the better understanding of all the immunologic aberrations expressed by the polygenic combinations and permutations associated with the atopic diathesis. Recognizing the immunopathologic features of AD readily underscores that AD without "atopy" is an oxymoron. Appreciating "pruritus" as the impetus ...

One of the functions of activated blood clotting factor XIII (FXIIIa) is the crosslinking of alpha2-antiplasmin (alpha2AP) to fibrin. This process results in localization and concentration of alpha2AP throughout fibrin, thereby making fibrin more resistant to digestion by plasmin. We reasoned that competition by chemically-modified inactive alpha2AP (mod alpha2AP) with ...

Managing most marine finfisheries to achieve optimum yields is an unattainable dream. Protecting these resources from serious depletion through precautionary management seems the only practical option. But even this is of limited application if we demand scientific data for each managed fishery. There are too few researchers to do the ...

We describe a patient with sporadic dystrophic epidermolysis bullosa associated with well-documented atopic dermatitis. We discuss this case in relation to a newly described clinical subtype of epidermolysis bullosa known as epidermolysis bullosa pruriginosa, a dystrophic variant associated with prominent pruritus. The relations of this case of sporadic dystrophic epidermolysis ...

PURPOSE: To describe the management of condensation on the posterior surface of a foldable acrylic intraocular lens during vitrectomy and fluid-air exchange. METHODS: A 70-year-old pseudophakic man with a foldable acrylic intraocular lens and open posterior capsule underwent vitrectomy and fluid-air exchange for repair of rhegmatogenous retinal detachment. RESULTS: During ...

Two bioactive novel triterpene glycosides named hovenidulciosides A1 and A2 have been isolated from a Chinese natural medicine, Hoveniae Semen Seu Fructus, the seeds and fruit of Hovenia dulcis Thunb. (Rhamnaceae). The absolute stereostructures of hovenidulciosides A1 and A2 with a migrated 16,17-seco-dammarane skeleton have been determined on the basis ...

Pityrosporum ovale is a lipophilic yeast that is part of the normal human adult cutaneous flora. It is both a saprophyte and an opportunistic pathogen associated with pityriasis versicolor, Pityrosporum folliculitis, seborrheic dermatitis, and some forms of atopic dermatitis. Systemic infections have also been described. In this article the diagnosis ...

The ethanolic extract of the leaves of Maprounea africana (Euphorbiaceae), a medicinal plant in the Congolese traditional medicine, induced hypothermia and reduced the latency to the loss of the righting reflex and prolonged the sleeping time induced by pentobarbital in mice. It also significantly delayed the onset of clonic convulsions ...

The major in vivo human metabolite of zatosetron is 8-alpha-methyl,8-beta-oxo zatosetron [N-O (1) zatosetron]. N-Desmethyl zatosetron (NdM zatosetron) and 3-hydroxy-zatosetron (3-OH-zatosetron) are minor human metabolites. In the rat, the primary in vivo metabolite is 3-OH-zatosetron. The enzyme kinetics of zatosetron metabolism were determined using human, rat, and monkey hepatic microsomal ...

Disposable and planned replacement lenses have become increasingly popular options for contact lens wearers. Optometrists must devise management strategies to avoid the many problems that have emerged from the use of these lens modalities: inappropriate patient selection, reduced frequency of eye examination, oversupply of lenses, improper policies for the release ...

The revised nomenclature for allergens is presented together with proposed nomenclatures for (a) allergen genes, mRNAs and cDNAs, and (b) recombinant and synthetic peptides of allergenic interest.

A comparison of the occupational dermatitis occurring in the same aircraft factory during 2 separate decades, 1955-1965 and 1981-1990, is presented. Subungual pulpitis is highly specific to this industry, because of the handling of resins and sealing agents. The number of cases dropped from 122 to 40, in accordance with ...

Three trials with torn bed nets impregnated with permethrin and deltamethrin were made under field conditions at the Soumousso Field Station and the Vallée du Kou rice-field area, both in Burkina Faso, and the Djoumouna fish pond area in the Congo Republic. Even a considerably torn correctly impregnated bed net ...

We report a case in which the lens nucleus dislocated into the vitreous cavity through a posterior capsular rupture during phakoemulsification. We performed a vitrectomy and removed the lens nucleus using the perfluorocarbon heavy liquid perfluoro-1,3-dimethylcyclohexane. The management of posterior dislocation of the lens nucleus during cataract surgery is discussed.

Physostigmine, administered intravenously, reversed postural hypotension induced by hypotensive agents, guanethidine, clonidine and dopamine2-receptor agonists. Postural hypotension, induced by pentobarbital sodium, was also reversed by physostigmine. Neostigmine reversed postural hypotension induced by clonidine following intracerebroventricular, but not intravenous administration. It is proposed that centrally acting cholinomimetic agents may be used ...

Recent work in marine ecology has reaffirmed an insight from fisheries science that knowledge about the production, dissemination and success of propagules can guide our management of populations and assemblages. Understanding the variable nature of recruitment relationships can both aid and hinder attempts at environmental monitoring, rehabilitation and innovative selection ...

Chronic unilateral keratitis developed in a 34-year-old woman who wore extended-wear contact lenses. A clinical response was not obtained until Nocardia asteroides was correctly identified as the causal agent. The response to 30% sulfacetamide was dramatic. We review the clinical presentation of Nocardia keratitis and recommendations for management. Use of ...

Flea allergy dermatitis is one of the most common causes of pruritus in dogs and cats. The degree of pruritus observed in the allergic animal varies widely and is dependent on numerous factors. Management of the flea-allergic patient is extremely frustrating for the owner and the veterinarian. Establishing an organized ...

Sesame oil has been reported to contain sesamolin, sesamin and sesamol as contact allergens. A female patient had cheilitis due to sesame oil in a lipstick. She reacted to sesamolin and sesamin, but not to sesamol. We carried out analysis of the sesame oil by high performance liquid chromatography. We ...

It can be categorically stated that any clinician who treats medical problems in women during the reproductive or the peripubertal years must be aware of risks of pituitary adenomas and available diagnostic and therapeutic modalities. Pituitary adenomas may present during the pubertal period in association with delayed or incomplete development ...

The theory of Ayurveda rests on the concepts of matter, vital principle, mind, and pure consciousness. It is a holistic theory of medicine, which aims at restoration of physical and mental health, and spiritual well-being in a sick person, so that he may self-actualize himself, and eventually, realize his nature ...

Rating of clinical performance and examination scores are employed to establish the final grade of students undertaking the surgical clerkship. This retrospective study was undertaken to determine whether there is a correlation between these two grading procedures in evaluating students. Grades for clinical performance and the scores obtained on the ...

Between 1968 and 1977, 87 patients underwent pneumonectomy at Rhode Island Hospital. Postoperatively, 25 patients developed arrhythmia (29 percent), giving rise to hemodynamic deterioration necessitating aggressive treatment. There were nine hospital deaths (10 percent). The effect of preoperative digitalis was analyzed in 68 patients over age 50 years.In Group 1, ...

This study suggests that there is a higher incidence of infectious corneal ulcers with soft contact lenses than with hard contact lenses. Pseudomonas aeruginosa was the most commonly identified organism associated with soft contact lens corneal ulcers. Early and aggressive management can improve the prognosis of this disease. A plan ...

Hard contact lens correction of aphakia is best performed with a single cut lens by a trial lens fitting. Lenticular design may be necessary. Continuous wear over age 70 may be necessary to achieve success and acceptance in more than 30% of aphakic wearers. Soft lenses are usually not practical ...

Iris damage in the area with loop contact can be prevented by lowering the dosage of steroids. An already damaged iris can be saved with phospholine iodide followed by phospholine iodide combined with atropine to immobilize the iris. On a low dose keratic precipitate-like spots will be formed on the ...

Cattle were more readily sensitised than guinea pigs to carboxymethylcellulose. Freund's complete adjuvant enhanced, but was not essential for, sensitisation. Schultz-Dale responses were obtained from pulmonary tissues of sensitised cattle but their sera failed to induce passive cutaneous anaphylaxis. Cattle could possibly be sensitised by carboxymethylcellulose contained in drug formulations.

In busy hospitals the increasing numbers of abortions must be performed without disturbing other hospital functions. Local anesthesia, vaginal tubal ligation and the use of outpatient beds are the operative and administrative adaptations described. Of 1545 abortions performed in Victoria Hospital, London, in 1971, 428 (32%) were done under local ...

The hematological features of phenacetin-induced hemolytic anemia are presented in order to make the physician aware of the abnormalities which suggest the use of an oxidant drug. The presence of "bitten out" red cells is the commonest initial clue to the existence of drug-induced hemolytic anemia. The diagnosis is confirmed ...
