The Marrara syndrome, like Halazoun in Lebanon, is a hypersensitivity reaction of the upper respiratory tract and buccopharyngeal mucosa to nymphs of Linguatula serrata. The condition follows the consumption of Marrara which consists of raw liver, lungs, trachea and rumen of goats and sheep infected with larvae of L. serrata. The adult worm is found in the nasal passages of dogs. Sheep and goats are infected by eggs from infected dogs. A survey that included 240 adult individuals in a village of endemic L. serrata infection in the Sudan showed that 20% experienced symptoms of allergic nasopharyngitis (Marrara syndrome) following the consumption of raw viscera of goats or sheep at least once in their life. In a prospective study of 24 patients who reported to hospital with the Marrara syndrome, the clinical features included itching in the throat and nose, unilateral conductive deafness, tinnitus and facial palsy. Secondary bacterial infection caused suppurative otitis media. Adult L. serrata parasites were found in the nasal passages of 56 and 47% of male and female dogs in the endemic area. Nymphs were recovered from the mesenteric lymph nodes, lungs and livers of goats in the area.

Fifteen patients with severe bacterial infection (12 with pneumonia) that developed in the resuscitation unit were subjected to the empirical monotherapy with piperacillin/tazobactam (P/T) or tazocin under an open randomized controlled experiment. P/T was administered intravenously in a dose of 4.5 g every 8 hours for 5 to 12 days (9.3 days on the average). When the monotherapy was not sufficiently efficient the patients were additionally treated with amikacin administered intravenously in a dose of 0.5 g every 8-12 hours. The favourable effect was observed in 14 patients (93 per cent). 7 of them were treated with P/T alone and 7 were treated with P/T in combination with amikacin. The primary pathogens were eradicated in 8 (73 per cent) out of the 11 patients treated with P/T alone. Before the treatment 34 microbial strains were isolated from the patients. 77 per cent of them were susceptible to P/T. The treatment with P/T resulted in eradication of 27 bacterial strains (79 per cent) including 67 per cent of gram-positive organisms and 86 per cent of gram-negative organisms. The adverse effects were recorded in 1 patient on the 6th day of the treatment: skin eruption and pruritus that required the treatment discontinuation. The results showed that the use of P/T in the initial empirical monotherapy of infections in patients under resuscitation conditions could be efficient.

Rhinitis is characterised by the presence of two or more of the following symptoms: nasal blockage, sneezing, rhinorrhoea (a persistent watery mucous discharge from the nose) and nasal itching which last for an hour or more on most days. Allergy is the commonest cause of chronic symptoms. Patients with allergic rhinitis often have a clear relationship between symptoms and allergen exposure, for example, during the tree/grass pollen season. Viral or bacterial infection is the commonest acute cause of symptoms and is usually self-limiting.

Fournier's gangrene is a genital and perineal necrotizing fascitiis with a rapid evolution. It's an affection caused by aerobic and anaerobic micro-organisms, eventually associated with a superinfection by micetes. It has characterised by a deep oedema associated with lancinating pain and itching in external genitalia, rapidly evolves to perineal tissues necrosis and purulence. At this stadium patient's general conditions are still serious and patient may be comatose. When toxaemia is over, demarcation of necrotic areas can be remarkable and granulation start growing. Fournier's gangrene seems to be related to an ischemic necrosis caused by obliterative endoarteritis and thrombosis of internal pudendal and deep and superficial external pudendal artery. The infection gateway may be subcutaneous tissue lesion associated to trauma or surgical procedures in immunodeficient organism. Diagnosis is mainly clinical but a superficial ecography could be useful to demonstrate thickening in subcutaneous tissue with normal testicles. Both of them were middle aged males, heavy smokers, affected by hypertension and COPD. In both cases there was polymicrobial Gram positive bacterial infection. Antibiotic systemic therapy and topic therapy were administered. The patient also received hyperbaric oxygen therapy. Thirteen days after the admittance, the infection was defeated and we could start the surgical cover. To cover the scrotal wound we have used split-thickness skin grafts taken from the right thigh. These grafts took at 100% and the patient was discharged seven days after surgical operations. Follow-up at six months and at one year showed any functional limitation and a good aesthetic result.

A maculopapular eruption with clinical and histological features similar to those previously described in Sphinx cats under the name of urticaria pigmentosa is reported in five unrelated Devon Rex cats. Physical examination revealed erythematous, occasionally crusted papules, with a bilaterally symmetrical linear distribution on the latero-ventral trunk in two cases and a diffuse distribution on the ventral thorax in the other three cats. One cat also had a greasy seborrhoea on the head and dorsum. Pruritus and pigmented macules were present only in cats affected by secondary bacterial infection. Histological examination of papules in all cats and of the lesional skin of the cat affected by greasy seborrhoea revealed the presence of a perivascular to diffuse mastocytic and eosinophilic infiltrate in the dermis. The mean numbers of nondegranulated and degranulated mast cells per mm(2) were 303.2 and 451.6, respectively. The condition waxed and waned in all cats, and exacerbations were controlled with prednisolone or essential fatty acids.

Scabies and pediculosis are diagnosed on an almost daily basis in many dermatology offices. Whether the patient seeks medical attention because of the often unbearable itch of scabies or because of the fear of lice infestations, the physician should be on the lookout for these ectoparasitic infestations. Secondary bacterial infection, resistance to medication, and the risk of spread of the infestations to family members and other close contacts may complicate the problem. Patients frequently have to battle the myths, prejudices, and even shame that are associated with such infestations.

A retrospective study of 232 elderly patients seen between August 1998 and April 2000 at the skin clinic in Princess Haya hospital, Aqaba, was undertaken to determine the prevalence of skin disorders, and those most commonly associated with diabetes mellitus, in the elderly. Eczema/dermatitis was the commonest skin disorder seen (25.9% of cases), followed by pruritus without skin lesions (15.1%), viral infection (14.7%, most commonly herpes zoster), fungal infection (13.8%), and bacterial infection (10.3%). Bacterial infection was the commonest skin disorder in patients with diabetes mellitus (62.5%), followed by fungal infection (50.0%). Skin diseases cause considerable morbidity in elderly people; health promotion and education can do much to reduce the risks of these disorders in the elderly, especially those with diabetes.

A 9-yr-old, female Bactrian camel (Camelus bactrianus) developed severe pruritus in June 1993. During the next 8 yr, the camel exhibited annual episodes of pruritus and epiphora, generally beginning in June and subsiding in October of each year. These signs could usually be controlled with topical agents and fly repellents, although pruritus flare-ups were effectively controlled with intermittent injections of diphenhydramine and corticosteroids. There were no signs during the colder months. The pruritus became more severe and difficult to control when the camel reached its 18th year. Histopathologic descriptions of skin biopsies taken from several sites suggested a hypersensitivity reaction with secondary changes because of bacterial infection or corticosteroid administration (or both). An intradermal test (IDT) performed using 62 allergens regionalized to Northern California resulted in 17 positive test sites. Hyposensitization therapy was initiated using allergens chosen on the basis of exposure, availability, and the results of the IDT, using standard protocols. The clinical signs of pruritus were markedly reduced in the 2 yr after the hyposensitization injections were initiated.

A series of 18 allergic cats with multifocal Malassezia spp. overgrowth is reported: atopic dermatitis was diagnosed in 16, an adverse food reaction in another and one was euthanized 2 months after diagnosis of Malassezia overgrowth. All the cats were otherwise healthy and those tested (16 out of 18) for feline leukaemia or feline immunodeficiency virus infections were all negative. At dermatological examination, multifocal alopecia, erythema, crusting and greasy adherent brownish scales were variably distributed on all cats. Cytological examination revealed Malassezia spp. overgrowth with/without bacterial infection in facial skin (n = 11), ventral neck (n = 6), abdomen (n = 6), ear canal (n = 4), chin (n = 2), ear pinnae (n = 2), interdigital (n = 1) and claw folds skin (n = 1). Moreover, in two cats Malassezia pachydermatis was isolated in fungal cultures from lesional skin. Azoles therapy alone was prescribed in seven, azoles and antibacterial therapy in eight and azoles with both antibacterial and anti-inflammatory therapy in three of the cats. After 3-4 weeks of treatment, substantial reduction of pruritus and skin lesions was observed in all 11 cats treated with a combined therapy and in five of seven treated solely with azoles. Malassezia spp. overgrowth may represent a secondary cutaneous problem in allergic cats particularly in those presented for dermatological examination displaying greasy adherent brownish scales. The favourable response to treatment with antifungal treatments alone suggests that, as in dogs, Malassezia spp. may be partly responsible for both pruritus and cutaneous lesions in allergic cats.

Pododermatitis is a common inflammatory skin disease of dogs. As pedal lesions are reported in many canine dermatoses, a methodical series of diagnostic tests is required to establish the underlying aetiology. However, laboratory/ancillary investigations may prove unrewarding, prompting a diagnosis of idiopathic disease. Various hypotheses have been proposed to explain the pathogenesis of idiopathic pododermatitis including pedal conformation, trauma, immunosuppression, bacterial infection, furunculosis and dermal granuloma formation. Idiopathic pododermatitis accounts for 0.5% of all dermatology referrals to the authors' clinic. A sub-group within this population is characterised histopathologically by epidermal hyperplasia, hyperkeratosis, spongiosis, dermal oedema and perivascular aggregates of lymphocytes and plasma cells. The term lymphocytic-plasmacytic pododermatitis (LPP) has previously been proposed to reflect the histological appearance of such lesions. Affected dogs, although systemically well, characteristically have pruritus, erythema, swelling, pain and alopecia of the feet. Although non-responsive to antimicrobial therapy, antiparasitic agents and elimination diets, these dogs typically respond well to immunomodulatory therapy.
