Larval Cyathostomes in Horse: Case Study Report

Larval Cyathostomes in Horse: Case Study Report A two-year-old Dutch Warmblood gelding presented with extreme weight loss and diarrhoea in December. The horse had been at pasture with seven others for the last three months with daily supplementary hay. The horse was rugged and had not been closely examined for six weeks however had been observed eating on a daily basis. On the day of admission to the hospital the horse had been seen standing alone, in-appetent with severe diarrhoea. On arrival to the hospital the horse was quiet, alert and responsive, body condition score 1/9 (284kg bwt). There was faecal staining down the hindquarters and tail. The heart rate and respiratory rate were elevated (76 beats per minute and 20 breaths per minute). Mucus membranes were pink and moist with a capillary refill time of 2seconds. Gastrointestinal sounds were increased. Skin tent was extremely prolonged, indicating significant dehydration. Abdominal ultrasound revealed a fluid filled colon and caecum with good SI motility and no evidence of bowl thickening. Although no abnormalities were detected per rectum, upon completion of the examination a large number of cyathostome larvae were visible on the rectal sleeve. Faecal analysis was negative for strongyle eggs. The significant clinicopathological abnormalities are presented below: Fibrinogen 6.3g/L (1.8-3.7g/L) Serum Amyloid A (SAA) 180mg/L ( Haematocrit (HCT) 45.1% (24-44%) Albumin 15g/L (31-38g/L) Blood lactate 3.1mmol/L (0.2-0.7mmol/L) Problem list Acute weight loss Poor body condition Diarrhoea Dehydration Differential diagnosis for diarrhoea Infectious: Samonellosis, Clostridium perfringens, Clostridia difficile, Lawsonia intracellularis, Parasitic: Strongylosis, larval cyathostomiasis Toxic: NSAID Miscellaneous: carbohydrate overload, sand enteropathy Due to the horse’s age, number of horses at pasture and poor worming history the most likely diagnosis was a larval cyathostomosis. Although the faecal worm egg count was negative this does not take into account the encysted burden of worms and therefore cannot rule out infection. The presence of red worm larvae on the rectal sleeve following rectal examination indicates the presence of larvae. An intravenous catheter was placed and maintainance fluids were administered to rectify the dehydration. 4L of plasma (Hypermune, Veterinary Immunogenics) was also given to provide anti-endotoxic and colloidal support. Dexamethasone (Dexadresson, Intervet) 0.05mg/kg IV every other day was administered initially. The horse was also started on fenbendazole (FBZ) (Panacur Guard) 7.5mg/kg SID for 5days. Additional supportive therapy included free access to palatable feed and fresh water. The following day, the horse was quiet with a moderate appetitite. Faeces became more watery so treatment with di-tri-octahedral smectite (Biosponge, Platinum Performance)1g/kg q6hrs per nasogastric tube and codeine phosphate (Codeine Phosphate, Crescent Pharma) 1mg/kg PO TID was started and adjusted daily according to faecal consistency. On day 3 the horse appeared slightly colicky and appetite reduced. Treatment with a single dose of flunixin meglumine (Finadyne, MSD Animal Health) 1.1mg/kg improved signs of abdominal pain. The following day the horse was brighter and appetite improved. The intravenous fluids were discontinued. At this point dexamethasone was replaced by oral prednisolone (Equisolon, Boerhinger Ingleheim) 1mg/kg PO SID. The diarrhoea improved over the following two days and on day 6 the codeine and biosponge were also discontinued. On day 7 of hospitalisation the horse was given moxidectin (MOX) (Equest, Pfizer) 0.4mg/kg to treat any parasites resistant to the fenbendazole therapy. A further blood sample on day 10 revealed improvement in HCT, fibrinogen and SAA. The albumin remained low at 15g/L but considering the horse’s dehydration on admission, this was slightly improved and would be expected to take weeks to return to a normal range. The horse was discharged. At this point the horse had a good appetite, was very bright and was passing normal droppings. Weight had increased from 284kg on admission to 305kg. Discussion Strongylid round worm, subfamily Cyathostominae, and infestation may affect up to 100% of pastured animals (Tolliver et al, 1987, Lyons et al, 1999, Lind et al, 2003). In adult horses, the disease is usually asymptomatic or observed in sub-clinical forms however in horses, which have not been treated, treated infrequently or are on heavily grazed pasture can reach hundreds of thousands (Chapman et al, 2003, Gasser et al, 2004). The most common clinical manifestation of cyathosome infection is associated with acute larval cyathostomosis (Murphy et al, 1997). The poor worming history, minimal pasture management and heavily grazed pasture in this case indicated that this was likely. As with this case larval cyathostomosis is usually diagnosed in horses of 1-3years of age and is most commonly associated with severe weight loss, weakness, acute or chronic diarrhoea, subcutaneous oedema, pyrexia and colic (Lyons et al, 2000). In the UK age ( The blood results in this case alongside the diarrhoea and weight loss indicated a protein losing enteropathy. A decrease in total protein levels, particularly albumin, and neutrophilia are common presentations of horses infested with cyathostomes (Steinbach et al, 2006). The synchronous reactivation of the encysted larvae (EL3) into the gut lumen can cause extensive bowl inflammation which can not only result in enteral protein loss and impaired nutrient absorption, but also entrance of bacterial toxins into the tissues (Abbot, 1998, Giles et al, 1985 and Reid et al, 1995). This can be fatal in up to 50% of cases (Love et al, 1999). The plasma administered in this case aimed to provide colloidal support due to the reduced albumin, and act as an anti-endotoxic agent (Tennant-Brown, 2011). The debilitated condition the horse was in in this case led to consideration of the most appropriate treatment. There is a concern over worsening of a horses condition following administration of anthelmintics, however there is a balance between this and a delay in treatment leaving sufficient time for recovery following anthelmintic treatment (Johns, 2014). Johns (2014) describes the potential for using fenbendazole in severely emaciated horses. The concern with determining treatment is that the mucosal stages constitute the major cyathostomin burden, which is not particularly susceptible to most anthemintics (Love and Mckeand 1997). Chemotherapeutic strategies are not always successful in severe cases however the main two drugs licensed treatments for encysted larvae are FBZ or MOX. The initial treatment used in this case was Fenbendazole 7.5mg/kg bwt administered daily for 5 consecutive days. It has been shown to provide >95% efficacy vs. total mucosal larvae, including >91% efficacy against inhibited EL3 (Duncan et al, 1998). A single dose of moxidectin 0.4 mg/kg bwt was administered on day 7. This has been shown to have a persistent effect and be effective against all life cycle stages, including 90.8% efficacy against EL3 (Reinemyer et al, 2003). There have been limited reports of resistance and as such is recommended for the treatment of larval cyathostominosis (Reinemyer et al, 2003 and Molento et al, 2008). The reason for this follow treatment with moxidectin is due to the world wide prevalence of FBZ resistance, and even 5day courses at 7.5 or 10mg/kg bwt cannot overcome this resistance (Tarigo-Martinie et al, 2001). Although there is little research to support it, clinicians often choose to treat larval cyathostomes with a 5day course of fenbendazole followed by moxidectin. Reasoning behind this maybe due to FBZ killing larvae at a slower rate and therefore avoids a severe anaphylactic reaction associated with larval death. Also due to the resistance seen with fenbendazole, it leads to a ‘belt and braces’ approach to remove the encysted parasites. A concern with moxidectin is the risk of toxicity in severely-debilitated horses. Because of its highly lipophilic nature, moxidectin can become highly concentrated in the serum of animals with little body fat, such as this case, which increases the risk of neurotoxicity as it able to cross the blood-brain barrier, which is described in the literature (Johnson et al, 1999 and Muller et al, 2003). In many reported cases clinical signs have been evident following treatment of affected horses, a syndrome thought to be due to the inflammatory reaction associated with parasite death. A study performed by Steinbach et al, (2006) found a five-day course of fenbendazole caused extensive inflammation and ulceration of the intestinal wall associated with parasite death. However moxidectin treatment led to disintegration of larvae without the severe inflammatory response which supports the use of the latter drug in treatment of clinical cases, and questions the treatment protocol used in this case (Steinbach et al, 2006). Anthelmintic treatment is often administered alongside steroid therapy, which is important if heavy larval loads are suspected as with this case. The inflammatory reaction created by parasite death is often managed with corticosteroid treatment. Often treatment is started prior to larvicidal medication particularly if heavy larval loads are suspected. This aims to prevent acute exacerbation of the disease by rapid death of encysted larvae (Church et al, 1986). Church et al (1986) found that the administration of steroids alongside the anthelmintics lead to a synergistic drug effect. The corticosteroid lessens the immune mechanisms contributing to larval arrestment allowing the mucosal larvae to resume maturation and therefore more susceptible to the action of anthelmintics (Church et al, 1986). Although there has been no further evidence for its use, in clinical practice there appears to be a therapeutic advantage with cyathostomosis cases in giving oral corticosteroid concurrently w ith anthelmintics (Love and McKeand, 1997). As this was a concern in this case corticosteroid treatment was used alongside anthelmintic therapy. Codeine Phosphate although not licensed in horses, was used in this case to provide symptomatic relief of diarrhoea. It works by reducing gastrointestinal secretions and delaying intestinal transit. There was improvement seen in faecal consistency after 48hours and the dose was altered accordingly (Murphy et al, 1997). Studies are currently underway to develop a diagnostic assay to allow the detection and quantification of mucosal cyathostomes to allow for targeted treatment (Proudman and Matthews, 2000). FEC underestimate the true parasite burden when larval populations predominate and luminal adult burdens are low (Dowdall et al, 2002). This was seen in this case where the FEC was negative however the clinical signs and presence of larval on the rectal sleeve all suggested larval cyathstomiasis. The successful outcome in this case supported the treatment protocol used. However after consideration of the literature it would be prudent to question whether moxidectin alongside corticosteroid therapy would provide less intestinal inflammation, reducing the severity of clinical signs alongside ensuring the death of the encysted parasites.

History of fashion in 1920s

History Of Fashion In The Twenties How the women and fashion changed? In sass fashion history, the initial break with the traditional styles stemmed from the inspiration drawn from the Aesthetic and Rational Dress Reform Movements of the late 19th century. Exciting theatrical costume designs which broke the rules also paved the way for more relaxed dressing. This was all fast forwarded during the war years and led to the major changes in construction of clothes and undergarments for the remainder of the century. Prohibition, the proliferation of Jazz, and the development of mass media were the hallmarks of the sass.Youth was at a premium because so many young people were killed during the war. As a result, teenagers had a new freedom that they used to usher in the Afro-influenced Jazz age. Clara Bow, Louise Brooks, Rudolf Valentine, and Josephine Baker were popular stars of the time, personifying many of the modern ideals. For women, face, figure, coiffure, posture and grooming becam e important fashion factors in addition to clothing. In particular, cosmetics became a major industry. Glamour was now an important fashion trend, due to the influence of the motion picture industry and the famous female movie stars.The sass saw the emergence of three major women's fashion magazines: Vogue, The Queen, and Harpers Bazaar. Vogue was first published in 1892, but its up-to-date fashion information did not have a marked impact on women's desires for fashionable garments until the ass's. These magazines provided mass exposure for popular styles and fashions. During the early sass, waistlines were at the waist, but were loose and not fitted. Women wore suits with long hemlines and somewhat full skirts, often with belts at the waist of the Jackets.Dress and suit bodices alike were worn loose, even baggy. By 923, waistlines began to drop to a point between the natural waist and hips, while styles continued to be loose and baggy. In 1924 the waistline dropped to the hip. In 1 925, â€Å"shift† type dresses with no waistline emerged. At the end of the decade, dresses were being worn with straight bodices and collars. Tucks at the bottom of the bodices were popular, as well as knife-pleated skirts with a hem approximately one inch below the knee. In 1928, styles changed again! Hemlines rose to the knee and dresses became more fitted.These changes laid the foundation for the elegantly styled fashions of the sass. Many garments of the sass fastened with buttons. The closer-fitting flapper- style dresses fastened with a continuous lap, usually applied to the left side seam of the garment. Hooks and eyes, buttons, or snaps were all utilized to fasten the lap. The zipper, first patented in 1893, was not utilized in garments until the latter part of the decade. It was originally known as a â€Å"locker†, and did not receive its current name until 1926. It was not widely used until the late sass.Cotton and wool were the abundant fabrics of the decad e. Silk was highly desired for its luxurious qualities, but the limited supply made it expensive. In 1891, â€Å"artificial silk† was first made from a solution of cellulose in France. After being patented in the United States, the first American plant began production of this new fabric in 1910. In 1924 this fiber became known as rayon. Rayon stockings became popular in the sass as a substitute for silk stockings. Rayon was also used in undergarments. Women, celebrating such liberties as the right to vote in , were now more daring than ever before.It was considered fun to smoke, visit speakeasies, wear makeup, swear, and otherwise shock conventional thinkers. In 1927 when short skirts were all the age; young women strove to show off their knees with increasing abandon. Many girls even rolled down their stockings and painted rouge on their knees in an effort to emulate a â€Å"naughty schoolgirl† look. The foot also became a focal point of fashion. Shoe styles were inf luenced by crazes like the Charleston, a dance that demented a securely fastened shoe with a low heel and closed toe.A single-bar pump with a pointed toe, high-wasted heel, and one tiny covered button was the most common style. High tongued, cutaway decorated, crossover, and t-straps were other popular elements. The curiosity for exotic arts and culture was fueled by the discovery of Egyptian King Tutankhamen tomb in 1922. Egyptian themes appeared in everything from furniture to clothing. Shoes also reflected this theme. Bright fabrics and brilliantly dyed leather – including metallic – were used to create some of the most exciting shoes ever seen.The heels were often works of art themselves. The late sass saw the adoption of two-toned spectators for men, perfect with the popular knickers. In the ass, men were still in a conservative mood. The wide trousers were still worn, sometimes as wide as 24 inches at the bottom! The knickers and ‘plus fours' were popular w ith sporty types, and were buckled 4†³ below the knee (hence the name ‘plus fours'). Light colors were favored in summer, but darker and animal fur was favored when the weather got cold.By now all the college boys were wearing the popular raccoon coat, and some of the women were too. The following are the events that affected fashion in sass and even today: Channel's pioneering Jersey sweater and pleated skirt. Ensembles are now accepted as easy wear. Debutante Daisy Fellows challenges convention wearing black when presented to the Queen at Bucking Palace instead of the traditional white. Ђ Dress Essentials magazine features scarves among accessories; color coordination becomes a conscious feature of the average woman's wardrobe. Ђ The Prince of Wales now orders all his trousers to be made with cuffs, and (unlike his father) wears suits in town. East European folk embroideries inspire the peasant look in women's Soviet Atelier of Fashion is formed. Wear. Bobbed ha ir becomes the rage. Tunisia takes off with â€Å"Tutankhamen† overzealous, Egyptian colors, scarab and lotus Jewelry, etc. The Textile Color Card Association of the United States is formed, n attempt to establish a standard system of colors identified by numbers. First feature on the â€Å"little black dress†. Ђ â€Å"Oxford bags† are worn by young graduates. The hemline is the shortest in history. US production of rayon viscose reaches 53 million pounds for the year. Vogue's More masculine elements enter female dress. The severely short â€Å"Eaton crop† haircut ousts bobbed hair. Jeanne Lanolin opens first boutique for men. Patent leather shoes are new. Nancy Canard, wearing African bangles to the elbows, is photographed by Man Ray. The press declares â€Å"fever chart† hemlines. Hat brims return to fashion. The first of Schizophrenia's tromped Leila sweaters are a resounding success. Ђ Men's Dress Reform Party is founded in Britain. A n ew femininity: hemlines are now longer for drawer, as well as evening. In Conclusion, Fashion was made available to a broader sector of the public as a result of modern retail policies and the idea that consumerism meant emancipation. Lighter garments of simpler cut and the electrification of the factories also made mass production possible. In many ways, the twenties established the themes and marketing policies that would be developed in the post-World War II period and that are so familiar to us today.

Industrialization The Demographic Transition Model

Industrialization is the large-scale introduction of manufacturing, advanced technical enterprises, and other productive economic activity into an area, society, country, etc (Industrialization). A visual representation that demonstrates industrialization and its stages is the Demographic Transition Model. The Demographic Transition Model refers to the change of a country s birth rate and population growth due to the effects of industrialization. This model displays the transition of countries from high birth and death rates to low birth and death rates, and as well as a higher population as a result of an industrialized economy. In other words, it is suggested that industrialization benefits a country, in terms of population (Grover, Drew). There is, however, a downside to industrialization, in which such economies and their activities leads to industrial pollution. Industrial pollution is one of the leading causes of pollution worldwide, for example, in China, pollution has become to be a serious problem as a result of their rapid industrialization. In the United States, the Environmental Protective Agency estimates that up to 50% of the nation s pollution is caused by industry (What Is Industrial Pollution?) and it is because of this that it has come to the attention of many nations the need to find alternatives to decrease the amount of industrial pollution.
