The diarrheal form may actually consist of three toxins muscle relaxant 5mg order baclofen 25mg line, one of which is hemolytic (Granum muscle relaxant alcohol addiction safe 10 mg baclofen, 2006) spasms near ovary order baclofen 10 mg otc. Foods associated with this organism and its toxic properties spasms back pain and sitting purchase baclofen 10 mg otc, include boiled and fried rice (principally the emetic form), while the diarrheal form has a wider occurrence and may be found in meats, stews, pudding, sauces, dairy products, vegetable dishes, soups, and meat loaf (Goepfert et al. The foods associated with the two types somewhat reflect the geographic distribution of the types, as the emetic type predominates in Japan, while in North America and Europe, the diarrhea type is most often seen. Evidence is accumulating that other species of Bacillus may elaborate food toxins, including Bacillus thurigensis, B. Sources of Staphylococcus include nose and throat discharges, hands and skin, infected cuts, wounds, burns, boils, pimples, acne, and feces. Other reservoirs include mastitic udders of cows and ewes (responsible for contamination of unpasteurized milk); and arthritic and bruised tissues of poultry. Foods usually are contaminated after cooking by persons cutting, slicing, chopping, or otherwise handling them and then keeping them at room temperature for several hours or storing them in large containers. Foods associated with staphylococcal poisoning include cooked ham; meat products, including poultry and dressing; sauces and gravy; creamfilled pastry; potatoes; ham; poultry; fish salads; milk; cheese; bread pudding; and generally high protein leftover foods (Cohen, 1972; Bryan, 1976, 1984; Minor and Marth, 1976; Crane, 1999; Dinges et al. Each of the diseases presented by the four categories is also associated with one or more toxins (Willshaw et al. Outbreaks in Europe are more often associated with contamination of recreational waters (swimming pools, lakes, etc. Other sources of contamination include person-to-person contact (especially in families and among institutionalized persons) and contact with farm animals especially following educational farm visits (Karch et al. At the basis of the potential problem is the use of inadequately treated manure for fertilizer. Adequate treatment of manure requires composting the manure for a minimum of 3 months during which, the heap must reach a temperature of 60 C and although this may be adequate to kill vegetative pathogens, it will not destroy spore-formers such as Clostridium perfringens or C. Survival of viruses and protozoa during composting is not known (Anonymous, 1999). Clinically, all these diseases present neurological deterioration and wasting, with the incubation period and interval from clinical onset to inexorable death determined by the dose of infective agent, its virulence and genetic makeup of the victim. Characteristic histologic lesions in the brain and spinal cord are vacuolation and "spongiform" changes. The infective agent can be transferred using preparations of neural tissue from infected animals across species barriers. The most effective method of transfer is direct injection into the brain or spinal cord, but transfer has been reported with intraperitoneal injection and oral "n" indicating seven subtypes. Vertical transfer (mother to offspring) has been reported among domestic cattle and lateral transfer through biting or injury (especially among mink) has also been reported. It is generally agreed that the infective agent is likely a variant of scrapie (endemic to sheep) and was transferred to cattle from rendered sheep via inadequately processed meat and bone meal protein supplement. The currently most accepted theory is that the infective agent is a modified form of a normal cell surface component known as prion protein PrPc (alpha-helix form), which when introduced into an organism causes a conversion of PrPc into a likeness of itself (i. The pathogenic form of the protein, PrP*, is both less soluble and more resistant to enzyme degradation than the normal form. The protein is resistant to heat, antimicrobials, ultraviolet or ionizing radiation, and is not consistently inactivated with alcohol, formaldehyde, glutaraldehyde, or sodium hydroxide. Substances Produced by Cooking Heterocyclic Amines Tolerances cannot be set for contaminants that are produced as a result of an action taken by the consumer. An example of this type of contaminant is heterocyclic amines, which are generated during cooking. They are formed as a result of high-temperature cooking of proteins (especially those containing high levels of creatinine) and carbohydrates. Normally, as a result of such heating, desirable flavor components are formed, for example, pyrazines, pyridines, and thiazoles. Acrylamide Prior to 2002, when Swedish investigators detected acrylamide in food (Table 30-28), it was of interest only to specialists in worker safety, as this chemical is an important intermediate in the manufacture of polyacrylamides.

Desmosomes play a crucial role in maintaining the adherence of the epidermal cells to one another spasms diaphragm cheap 10 mg baclofen fast delivery. With further outward displacement the differentiating cells of the spinous layer become flattened spasmus nutans purchase baclofen cheap, and refractile keratohyalin granules appear in the cytoplasm muscle relaxer z buy baclofen 10 mg without prescription, accounting for the designation of granular layer that rests just below the stratum corneum spasms right side purchase baclofen 10 mg without prescription. These granules are the site of active synthesis of filaggrin, which causes keratin filaments to aggregate in parallel array, forming the tough, "chemically resistant" internal structure of the stratum corneum cells. The transformation from viable granular cells to anucleate, non-viable Figure 519-1 Structure of the skin. The cornified layer consists of up to 25 layers of tightly packed, highly flattened horny cells. The differentiation of the epidermal cells involves the formation of fibrous proteins known as keratin. The process of maturation of the epidermis (cornificiation) is complete in the stratum corneum, yielding cells with mature keratin, namely, a system of filaments embedded in a continuous matrix (which is probably derived from the keratohyaline granules) within a thickened cell membrane. The stratum corneum limits the rate of passage of ions and molecules into and out of the skin. The insolubility and protective qualities of the stratum corneum are the result of (1) masses of keratin fibers embedded in keratohyaline within the corneocytes, (2) the thickened cell membrane or cornified envelope, and (3) the deposition glucosylceramide and acylceramines in the intercellular spaces between the corneocytes by lamellated membrane bound organelles found in the upper spinous layer. The basal layer of epidermis has a permanent population of germinal cells whose progeny undergo the specific pattern of differentiation just described. The new keratinocytes require about 14 days to evolve into stratum granulosum cells and another 14 days to reach the surface of the stratum corneum and be shed. Proper control of proliferation of basal cells and their subsequent orderly differentiation into keratinized stratum corneum cells produce the smooth, pliable surface of the skin. Alterations in the homeostatic state of cell division, defects in differentiation, or changes in exfoliation from the surface can lead to irregularities in the skin surface, characterized as roughening, scaling, and hyperkeratosis (accumulation of excessive layers of stratum corneum). Both are dendritic cells with cytoplasmic arms that stretch out to contact the keratinocytes in their vicinity. Melanocytes evolve in the neural crest of the embryo and migrate to the skin in early embryonic life. These cells synthesize brown, red, and yellow melanin pigments that give the skin its distinctive coloration. Melanocytes contain submicroscopic organelles (melanosomes) that synthesize melanin. Additional non-enzymatic oxidation and polymerization occur to form the final product, melanin. Two kinds of melanin are recognized: eumelanin (brown-black biochrome) and phaeomelanin (yellow-red biochrome that contains large quantities of cysteine). The genetic make-up of the individual determines which melanin is produced, thus providing the various colors and hues of skin and hair. Once melanosomes are fully melanized, the resulting granules are transported out the dendritic processes of the melanocyte and transferred into the adjacent epidermal cells or hair. They contain surface receptors for immunoglobulins, and Ia-antigens, capturing external antigenic materials that contact the skin and circulating them to draining lymph nodes. Beneath the epidermis lies the principal mass of the skin, the dermis, which is a tough, resilient tissue with viscoelastic properties. It consists of a three-dimensional matrix of loose connective tissue composed of fibrous proteins (collagen and elastin) embedded in an amorphous ground substance (glycosaminoglycans). At the microscopic level the collagen fibers resemble an irregular meshwork oriented somewhat parallel to the epidermis. Coarse elastic fibers are entwined in the collagenous fibers and are particularly abundant over the face and neck. This fibrous and elastic matrix serves as a scaffolding within which networks of blood vessels, nerves, and lymphatics intertwine and the epidermal appendages, sweat glands, and pilosebaceous units rest. The structures situated at the interface between the epidermis and dermis constitute an anatomic functional unit of complex membranes and lamellae laced by divergent types of filaments that together serve to support the epidermis, weld the epidermis to the dermis, and act as a filter to the transfer of materials and inflammatory or neoplastic cells across the junction zone. At the level of light microscopy, this boundary zone is seen as an undulating pattern of rete ridges (downward finger-like or ridgelike extensions of the epidermis) and dermal papillae (upward projections of the dermis into the epidermis) (see. Electron microscopic, immunoelectron microscopic, immunologic, biochemical, and genetic studies have elucidated the complexity of this region and are providing new insights into the pathogenesis of a variety of cutaneous diseases. Keratin filaments, hemidesmosomes, lamina lucida, lamina densa, anchoring filaments, and anchoring fibrils each function to maintain different levels of basement membrane adhesion.

The neurologic effects are due to a similar action on voltage-sensitive sodium currents in nerve fibers (Murai et al spasms side of head order baclofen on line. In Greece about 2500 years ago spasms near ovary buy baclofen 25 mg on-line, Xenophon described a serious condition called "mad honey poisoning" that developed in his soldiers after they had eaten honey contaminated with grayanotoxins zopiclone muscle relaxant buy baclofen 10 mg online. The effect of the toxins is marked bradycardia muscle relaxant creams over the counter cheap 10 mg baclofen, hypotension, oral paresthesia, weakness, and gastrointestinal upset, resembling aconitine poisoning. Grayanotoxins bind to sodium channels in cardiac and muscle cells, increasing sodium conductance (Maejima et al. Toxicity has been reported in goats and in sheep eating leaves of Rhododendron macrophyllum (Casteel and Wagstaff, 1989). Species containing significant concentrations of pyrrolizidine alkaloids are responsible for liver damage in the form of hepatic veno-occlusive disease associated with lipoperoxidation (Bondan et al. Hepatitis in cattle grazing on Senecio has been reported in Africa and Asia as well as in the United States. The condition is progressive and death occurs after weeks or months of grazing on contaminated pasture. Different animal species show marked differences in susceptibility to the alkaloids. Susceptible species are rats, cattle, horses, and chickens; resistant species are guinea pigs, rabbits, gerbils, hamsters, sheep, and Japanese quail. These differences are in general related to the rate of hepatic pyrrole formation, although other sources of differences must be present (Huan et al. Human deaths from pyrrolizidine alkaloids have been reported in several countries, including South Africa, Jamaica, and Barbados. In Afghanistan, there was an epidemic of hepatic venoocclusive disease from consumption of a wheat crop contaminated with seeds of a species of Heliotropium (Tandon et al. The clinical signs associated with the liver damage resemble those of cirrhosis and some hepatic tumors may be mistaken for the hepatotoxicity (McDermott and Ridker, 1990). The clinical condition is a form of the Budd­Chiari syndrome, with portal hypertension and obliteration of small hepatic veins. Human consumption also occurs from Symphytum in herbal preparations, such as "comfrey tea" (Rode, 2002). In addition to veno-occlusive damage to the liver, the alkaloids in Symphytum have been shown to be tumorigenic and mutagenic in rats (Mei et al. Lantana camara (Verbenaceae) has been called one of the 10 most noxious weeds in the world. It is an attractive shrub, native to Jamaica and commonly cultivated in greenhouses. An unusual property of the plant is that it inhibits the growth of neighboring plants. One that has been shown to induce hepatotoxicity is lantadene A (22-betaangeloyloxy-3-oxo-olean-12-en-28-oic acid) (Sharma et al. Mushroom toxins Many of the nonedible mushrooms may cause gastrointestinal distress but most are not life threatening. Repeated consumption of the false morel, Gyromitra esculenta, has been reported to cause hepatitis as well as gastrointestinal disorders (Michelot and Toth, 1991). Several species of three genera of mushrooms are responsible for most fatal poisoning from consumption of wild mushrooms, Amanita, Galerina, and Lepiota (Karlson-Stiber and Persson, 2003). Phalloidin is a cyclic heptapeptide that may be responsible for the diarrhea that develops 10­12 hours after ingestion of A. Phalloidin combines with actin in muscle cells, but is not readily absorbed from the gastrointestinal tract (Cappell and Hassan, 1992). The alpha-, beta-, and gamma-amanitins are bicyclic peptides (mw 900) and are absorbed. The most toxic, Vasoactive Chemicals Mistletoe is a parasitic plant on trees and has over the centuries been considered either holy or demonic. The poisonous qualities of mistletoe were recognized by John Gerard in his herbal in 1597. He described a case of poisoning from mistletoe berries in which the tongue was inflamed and swollen, the mind dostraught, and strength of heart and wits enfeebled. The American mistletoe, Phoradendron flavescens, is a member of the same family as the European mistletoe (Viscum album, Loranthaceae).

Spironolactone spasms in neck purchase baclofen online pills, the potassium-sparing diuretic spasms down legs when upright discount baclofen 25 mg with amex, has antiandrogenic properties that have made it a useful adjunctive therapy in doses of 100 to 200 mg/day in women with difficult-to-control acne muscle relaxant chlorzoxazone baclofen 25mg generic. Oral contraceptives may also benefit some women with moderate to severe acne zoloft spasms purchase genuine baclofen on-line, particularly if flares are correlated to menstrual cycles. Rosacea is a chronic inflammatory disorder affecting the blood vessels and pilosebaceous units of the face in middle-aged individuals. Patients with rosacea have papules and pustules superimposed on diffuse erythema and telangiectasia over the central portion of the face. An important component is easy flushing and blushing of the face often accentuated when alcohol, caffeine, or hot spicy foods are ingested. Hyperplasia of the sebaceous glands, connective tissue, and vascular bed of the nose sometimes causes rhinophyma, which is a large, red, bulbous nose (Color Plate 12 C). Ocular complications, which occur in a significant number of rosacea patients, include blepharitis, chalazion, conjunctivitis, and progressive keratitis that can lead to scarring and blindness. Rosacea can usually be differentiated from adult acne by the lack of comedones and the prominent vascular (flushing/telangectasia) component. Other causes of a red face in adults such as the malar eruption of acute systemic lupus erythematosus and the heliotrope rash of dermatomyositis, seborrheic dermatitis, and perioral dermatitis must be considered. Rosacea and the eye complications usually respond well to tetracycline and/or oral metronidazole, but the antibiotic must be continued for life (at the lowest dose that suppresses the condition) because rosacea recurs when therapy stops. Topical antibiotics (metronidazole [MetroGel] or Noritate) can be helpful alone or in combination with low-potency topical steroids. Non-infectious causes of pustular disease include perioral dermatitis, which may be caused by potent topical steroids and is a 2286 variant of acne. It presents as perioral and periorbital red scaling patches, papules, and pustules. Pustular psoriasis is a variant of psoriasis characterized by pustules localized to the palms and soles or generalized over the entire body. It presents as discrete red papules or pustules with a red base and is found principally over the trunk, especially the back. Folliculitis, a Staphylococcus aureus infection of the hair follicle, appears as pustules with a red rim with hair emanating from the center of the pustule. Folliculitis typically occurs in hairy regions where clothing rubs (buttocks, thighs) or on the face. Occasionally, the follicular infection can extend more deeply to form a larger, red, fluctuant nodule from one (furuncle) or more follicles (carbuncle). Systemic antibiotics such as erythromycin or dicloxacillin usually clear extensive infections; topical antiseptic cleansers such as povidone-iodine or chlorhexidine can resolve mild folliculitis and may be useful in preventing recurrences. Hot tub folliculitis is a generalized, pruritic folliculitis caused by Pseudomonas aeruginosa that is acquired in contaminated hot tubs, whirlpools, or swimming pools. It usually begins 6 hours to 5 days after hot tub soaking and affects many people using the facility. It appears as a vesicular and then pustular eruption over the trunk, buttocks, legs, and arms but spares the head and neck (Color Plate 16 C). In most instances, the folliculitis resolves within 7 to 10 days without specific treatment. Candidiasis appears as beefy red patches in intertriginous, moist areas characteristically surrounded by satellite pustules. Topical agents such as clotrimazole and miconazole must be used two or three times a day for many weeks before the infection clears. Dermatophytes can, at times, infect hair follicles and result in pustules, particularly in the beard (tinea barbae) and scalp (kerions). These intense inflammatory reactions to superficial dermatophytes (especially Trichophyton verrucosum) respond to griseofulvin therapy, although a short course of oral corticosteriods is also useful. Deep fungal infections such as blastomycosis, sporotrichosis, and coccidioidomycosis may cause pustules as well as verrucous, ulcerative papules and nodules. Sporotrichosis characteristically spreads up cutaneous lymphatics and appears as nodular, pustular lesions in a linear distribution. Certain medications can lead to a follicular eruption, including lithium and hormonal/steroid preparations. Erythematous and urticarial papules and pustules present on the upper chest, back, and proximal extremities; they may be treated with potent topical steroids, antihistamines, and even itraconazole.

Glycopyrrolate is a quaternary ammonium salt, hence, it is positively charged at physiological pH. The mean elimination half-life increases from 19 minutes in patients with normal kidney function to 47 minutes in patients with severe kidney impairment, indicating that renal disease impairs the elimination of glycopyrrolate. Although it is excreted in the urine largely as unchanged drug, glycopyrrolate reinforces a number of principles about xenobiotic biotransformation, the most important of which is: xenobiotic biotransformation is the process-actually a series of enzyme-catalyzed processes-that alters the physiochemical 161 properties of foreign chemicals (xenobiotics) from those that favor absorption across biological membranes (namely, lipophilicity) to those favoring elimination in urine or bile (namely, hydrophilicity). Without xenobiotic biotransformation, the numerous foreign chemicals to which we are exposed (which includes both man-made and natural chemicals such as drugs, industrial chemicals, pesticides, pollutants, pyrolysis products in cooked food, alkaloids, secondary plant metabolites, and toxins produced by molds, plants, etc. Furthermore, absent xenobiotic biotransformation, many of the drugs in use today would have an unacceptably long duration of action. In contrast, drugs that are not lipophilic, like glycopyrrolate, are not absorbed from the gastrointestinal tract (hence they are not orally active), and if they are administered parenterally they are not biotransformed (because they are already hydrophilic), and they are rapidly eliminated from the body. The enzymes that catalyze xenobiotic biotransformation are often called drug-metabolizing enzymes. This acronym is used widely in the pharmaceutical industry to Copyright © 2008 by the McGraw-Hill Companies, Inc. This chapter describes some fundamental principles of xenobiotic biotransformation, and describes the major enzyme systems involved in the biotransformation (or metabolism) of drugs and other xenobiotics. The examples given are biased toward drugs and human enzyme systems for two reasons. First, many of the fundamental principles of xenobiotic biotransformation stem from such studies. This is especially true of drugs with a narrow therapeutic index (where the toxic dose is not much greater than the therapeutic dose), which have revealed a large number of genetic and environmental factors that affect xenobiotic biotransformation and, hence, drug toxicity. Second, adverse drug reactions are one of the leading causes of death in the United States. Nevertheless, the following points, which might be considered principles or rules, apply in the majority of cases: Point 1 Xenobiotic biotransformation or drug metabolism is the process of converting lipophilic (fat soluble) chemicals, which are readily absorbed from the gastrointestinal tract and other sites, into hydrophilic (water soluble) chemicals, which are readily excreted in urine or bile. For example, acetylation and methylation are biotransformation reactions that can actually decrease the water solubility of certain xenobiotics. Point 2 the biotransformation of xenobiotics is catalyzed by various enzyme systems that can be divided into four categories based on the reaction they catalyze: 1. The conjugation reactions include glucuronidation, sulfonation (often called sulfation), acetylation, methylation, conjugation with glutathione (mercapturic acid synthesis) and conjugation with amino acids (such as glycine, taurine, and glutamic acid). Examples of the major chemical groups that undergo biotransformation together with the enzymes that commonly mediate their biotransformation are given in Table 6-2 (Williams et al. Xenobiotic biotransformation is generally catalyzed by enzymes, but there are exceptions. For example, hydrolysis of certain carboxylic and phosphoric acid esters, reduction of sulfoxides to sulfides. Point 3 In general, individual xenobiotic-biotransforming enzymes are located in a single organelle. However, in such cases, the enzyme name generally refers to two or more enzymes, each with its own distinct subcellular location.
