The study of one hundred and fifty cases of chronic urticaria observed, gave the following results: higher female frequency, usual beginning at adult age, relative absence of digestive problems. For the last of these results we nevertheless noted numerous insignificant functional features, a few examples of colitis, a number of cases of non-functioning gall-bladder. Frequency of sensitivity to foods, preservatives, colouring agents, medical substances, principally shown by provocation tests (the latter present a considerable interest, and merit frequent use); importance of bacterian, mycotic, parasitic origins; little importance of atopy; frequency of minor psychogenic disorders. A contributing role might be played by spasmophily. The therapy includes the following basic treatment; antihistaminic drugs (mainly hydroxyzine hydrochloride and cyproheptadine hydrochloride) and a diet which eliminates recognized urticaria causing foods. In addition, a supplementary treatment destined to eliminate the factors shown to be responsible for the outbreak, must be prescribed.

The case of a woman suffering from urticaria of the colon is reported. The original endoscopic images were described and its allergic (corticotrophin) origin was documented through clinical arguments and in vivo and in vitro tests. The term acute allergic colitis seems to be more suitable taking into account the distribution, the cause and the development of this disease.

Food allergy in childhood is a popular subject which has attracted disapprobation from certain quarters because of overinflated claims based on flimsy evidence. In this article food intolerance and allergy are defined and the pathogenesis of food allergic reactions is considered. There is a description of the role that food allergy may play in urticaria, angioedema, anaphylaxis, eczema, asthma, rhinitis, cow's milk sensitive enteropathy, infantile colitis, inflammatory bowel disease, migraine and hyperactivity. Factitious food allergy is discussed and the general unhelpfulness of 'allergy testing' commented upon. Finally there is a description of the use of various exclusion diets in the diagnosis and treatment of food allergic disorders. It is concluded that food allergy is important in an increasing number of childhood diseases, but it is not clear what proportion of children with a given condition will respond to dietary measures. The importance of ensuring that exclusion diets are nutritionally adequate is stressed, and there is a plea to remember that an exclusion diet might be worse than the disease itself.

To investigate the clinical signs of food allergy is to open new horizons for the understanding of worrying acute symptoms for the patients and too often only symptomatic treatment. It is also possible to take control in a more logical way of illnesses that are classified as chronic and so incurable. The clinical examination requires great attention and much listening. Urticaria, eczema, rhinitis, asthma, colitis are the most frequent symptoms. More rarely, there may be certain migranes or lipoid nephrosis in children.

In the inter-war period physicians elaborated numerous 'biotherapies' grounded in the complex interactions between physiology, bacteriology and immunology. The elaboration of these non-specific biological treatments was stimulated by the theory of generalized anaphylaxis that linked the violent reaction to a foreign protein to a broad array of chronic diseases, from asthma and urticaria to rheumatism or chronic colitis. Such diseases were perceived as the result of an 'abnormal reactivity' to a sensitisation of tissues and organs by bacteria and by foreign proteins, a view that provided an effective bridge between new concepts derived from bacteriology and immunology and the long-standing pathological tradition. Accordingly, physicians attempted to treat these conditions through specific desensitisation and non-specific biological therapies: peptone treatment, protein therapy, haemotherapy, 'antivirus' or 'opotherapy'. Therapies that attempted to neutralise the harmful effects of chronic infections through 'desensitisation' were not seen as marginal medical practices, but were promoted by leading advocates of the 'Pasteurian sciences', such as Richet, Widal, Vallery-Radot, Wright and Fleming. They also led to development of new products by the pharmaceutical industry.

Blastocystis spp. are widely prevalent extra cellular, non-motile anerobic protists that inhabit the gastrointestinal tract. Although Blastocystis spp. have been associated with gastrointestinal symptoms, irritable bowel syndrome and urticaria, their clinical significance has remained controversial. We established an ex vivo mouse explant model to characterize adhesion in the context of tissue architecture and presence of the mucin layer. Using confocal microscopy with tissue whole mounts and two axenic isolates of Blastocystis spp., subtype 7 with notable differences in adhesion to intestinal epithelial cells (IEC), isolate B (ST7-B) and isolate H (more adhesive, ST7-H), we showed that adhesion is both isolate dependent and tissue trophic. The more adhesive isolate, ST7-H was found to bind preferentially to the colon tissue than caecum and terminal ileum. Both isolates were also found to have mucinolytic effects. We then adapted a DSS colitis mouse model as a susceptible model to study colonization and acute infection by intra-caecal inoculation of trophic Blastocystis spp.cells. We found that the more adhesive isolate ST7-H was also a better colonizer with more mice shedding parasites and for a longer duration than ST7-B. Adhesion and colonization was also associated with increased virulence as ST7-H infected mice showed greater tissue damage than ST7-B. Both the ex vivo and in vivo models used in this study showed that Blastocystis spp. remain luminal and predominantly associated with mucin. This was further confirmed using colonic loop experiments. We were also successfully able to re-infect a second batch of mice with ST7-H isolates obtained from fecal cultures and demonstrated similar histopathological findings and tissue damage thereby coming closer to proving Koch's postulates for this parasite.

Acquired angioedema due to C1 inhibitor deficiency (C1INH-AAE) is a rare and potentially fatal syndrome of bradykinin-mediated angioedema characterized by episodes of angioedema without urticaria. It typically manifests with nonpitting edema of the skin and edema in the gastrointestinal (GI) tract mucosa or upper airway. Edema of the upper airway and tongue may lead to life-threatening asphyxiation. C1INH-AAE is typically under-diagnosed because of its rarity and its propensity to mimic more common abdominal conditions and allergic reactions. In this article, we present the case of a 62-year-old male with a history of recently diagnosed chronic lymphocytic leukemia (CLL) who presented to our hospital with recurrent abdominal pain, initially suspected to have Clostridium difficile colitis and diverticulitis. He received a final diagnosis of acquired angioedema due to C1 esterase inhibitor deficiency due to concomitant symptoms of lip swelling, cutaneous nonpitting edema of his lower extremities, and complement level deficiencies. He received acute treatment with C1 esterase replacement and icatibant and was maintained on C1 esterase infusions. He also underwent chemotherapy for his underlying CLL and did not experience further recurrence of his angioedema.

Dermatitis herpetiformis is a rare, chronic autoimmune disorder characterized by intense pruritic papules and vesicles, which can be associated with celiac disease and other autoimmune disorders. Its histologic characteristic is the accumulation of neutrophils within the papillary dermis with granular deposition of immunoglobulin A (IgA) observed under direct immunofluorescence. Herein, we report a 58-year-old woman who presented with a vesicular rash on the buttocks. The patient reported a recent history of genital herpes, Entamoeba histolytica colitis, recurrent hives, and eczema. A representative biopsy demonstrated features of spongiotic dermatitis and focal papillary dermal neutrophilic aggregates. Direct immunofluorescence revealed fibrillary IgA deposition in the papillary dermis, granular C3 deposition at the dermal-epidermal junction, and dermal papillae. The overall clinical, histologic, and DIF findings were consistent with those of dermatitis herpetiformis. The fibrillar IgA pattern is rare and easily overlooked by the unwary. Pathologists should be aware of this rare pattern, especially when the histologic findings are not classic.

The majority of individuals with Strongyloides stercoralis (S. stercoralis) colitis are clinically asymptomatic. Symptomatic individuals may complain of nonspecific gastrointestinal symptoms, such as abdominal pain, intermittent or persistent diarrhea, nausea, or loss of appetite. In addition, skin manifestations such as recurrent urticaria can occur. If infection is not diagnosed and left untreated, it can lead to chronic inflammation of the gastrointestinal tract. It is well documented that chronic colitis such as inflammatory bowel disease can predispose individuals to colorectal cancer. Additionally, there is evidence of chronic parasitic infections inducing the development of cancers in other organs within the gastrointestinal tract. In this case vignette, we describe a case of chronic Strongyloides stercoralis infection in a Peruvian woman presenting with colorectal cancer.
