Cold urticaria is defined as a urticarial and/or angioedematous reaction of the skin to contact with cold objects, water or air. Types of urticaria associated with infectious diseases, such as mononucleosis, rubeola, varicella, syphilis, hepatitis, and HIV infection have been reported. We present the case of a patient who developed cold urticaria associated with acute serologic toxoplasmosis. The patient was a 34-year-old man who for the previous 2 months had presented cutaneous pruritus accompanied by several papular lesions in parts of the skin exposed to cold as well as those in contact with cold water. The result of an "ice-cube test" was positive. Serologic tests for Toxoplasma gondii showed an IgG level of 68 UI/ml and were positive for IgM, while a test for cryoglobulins was positive. One month later cryoglobulins were negative and a serologic test for T. gondii showed an IgG concentration of 75 UI/ml and positive IgM. Three months later cryoglobulins were still negative, IgG for T. gondii was 84 UI/ml, and IgM was positive. After 6 months cryoglobulins were still negative, IgG level was 68 UI/ml and IgM was still slightly positive. In the final evaluation, 14 months later, IgG level was 32 UI/ml and IgM was negative. The patient continues to present clinical manifestations of cold urticaria, although he has experienced some improvement and his tolerance to cold has increased after treatment with cetirizine.

Emergency consultations happen frequently in gynaecology and may be due to abdominal pain, itching, utero-vaginal bleeding, rape, emergency contraception, insertion of foreign bodies, prolapse and urinary tract infection. Considering pregnancy in patients with child bearing potential is essential. Vaginal bleeding may be due to atrophy, infection, carcinoma or pregnancy. In the latter it is crucial to differentiate between ectopic, pathologic or physiologic pregnancy. In postmenopausal women further investigations by the gynaecologist are mandatory to exclude malignancy. Patients who have been raped need psychological, forensic and gynaecological support. Sexually transmitted disease including HIV must be considered and prophylactic drugs should be administered. If unprotected intercourse has occurred the "morning after pill" can be considered within 72 hours after intercourse or an IUD up to five days. Prolapse occurs rarely as an acute problem but may induce urinary retention. Urinary tract infection is a common complaint and should be treated with antibiotics.

Praneem polyherbal formulations containing purified extracts of Azadirachta indica (neem tree) have shown activity against HIV and sexually transmitted disease pathogens in studies in vitro. The product also has contraceptive properties. This has prompted its development as a possible microbicide. We evaluated the safety of Praneem polyherbal tablet use among HIV-uninfected women. Twenty eligible women were enrolled in a Phase I open-label study requiring 14 days of consecutive intravaginal use of Praneem polyherbal tablets. Nine (45%) participants experienced 17 episodes of genital irritation. Transient genital itching was reported by eight (40%) participants, burning micturation by two (10%) and lower abdominal pain, genital burning and intermenstrual spotting by one (5%) each. On colposcopy, petechial haemorrhage was observed in two participants, one on day 7 and the other on day 14, and both were resolved without any treatment. There were no serious adverse events. Praneem polyherbal tablets were found to be safe for once daily intravaginal use for 14 consecutive days in sexually active HIV-uninfected women and a Phase II study may be taken up as a priority.

The skin is a highly exposed organ during vacation times, especially during travel to countries with subtropical and tropical climates. Prolonged stay in these countries significantly increases the risk of contracting rarely seen dermatoses such as leishmaniasis, larva migrans and myiasis. The bites of various flies may provoke itching and excoriations that may be infected with Staphylococcus aureus and/or hemolytic streptococci, resulting in impetigo, furunculosis or erysipelas. Elderly persons spending weeks in the tropical sun may develop drug-induced phototoxic or photoallergic rash due to concomitant medication for cardiovascular or rheumatic diseases. Acute sunburn is considered a short-lasting problem, but in children it increases the risk of malignant melanoma in later years. Also of concern is chronic UV exposure, which increases the risk of premalignant and malignant skin tumors. Finally, mucocutaneous manifestations arising weeks and months after returning from vacation should raise suspicions of sexually transmitted syphilis and HIV.

A 52-year-old black woman presented with a 2-day history of lower lip swelling 5 days after starting a new medication, lisinopril. She had never experienced similar episodes in the past. She denied shortness of breath, tightening of the throat, swelling of the tongue, generalized cutaneous eruption, urticaria, or pruritus. She also denied symptoms consistent with facial paresis. Her past medical history was significant for hepatitis C infection, coronary artery disease, and hypertriglyceridemia. She had a 15 pack-year smoking history and denied both alcohol and drug abuse. She had never received a blood transfusion and was HIV negative. Physical examination disclosed a tender, swollen, and erythematous lower lip with induration, oozing, and crusting (Figure 1). Pinpoint openings evident throughout the lip surface exuded a clear, sticky, mucoid secretion. Tongue, parotid glands, and regional lymph nodes were normal. The working diagnosis was angioedema secondary to lisinopril. The presumptive offending drug was discontinued, and conservative therapy (topical clobetasol ointment, oral ranitidine, and oral fexofenadine) was initiated. Despite treatment, signs and symptoms persisted unabated. One week after initial presentation, a punch biopsy of her lower lip was taken to rule out granulomatous cheilitis and sarcoidosis. Histopathology included diffuse lymphohistiocytic infiltrate, minimal microabscess formation, and notable absence of granulomata. There was neither hypertrophy nor detectable abnormality of the salivary glands, with the exception of infiltrating mononuclear cells. Based on the clinical history and compatible pathologic findings, a diagnosis of cheilitis glandularis was made. Specifically, crusting and erosion clinically suggested a diagnosis of the superficial suppurative subtype of cheilitis glandularis. The patient received oral penicillin (dicloxacillin, 1.0 g/d) combined with oral fluoroquinolone (ciprofloxacin, 1.0 g/d). Within 2 weeks of starting the antibiotics, the lip swelling significantly decreased (Figure 2) and the patient was left with a mildly indurated nodule at the labial commissure. Following a 4-week course of continued antibiotic treatment, the lip returned to near baseline state. At both 6-month and 1-year follow-up visits, the lip remained normal.

Pruritic Papular Eruption with Human Immunodeficiency Virus infection (PPE-HIV) is characterized by symmetrically distributed papules with pruritus in the skin of patients suffering advanced HIV infection. Although known since 1985, the etiology of this symptomatic dermatitis is unclear. We set out to characterize the phenotype of the infiltrating cells and the cytokine profile in the lesions, as an attempt to contribute to determining its etiopathogenesis. Clinical data and histological, immunohistochemical, and ultrastructural features of skin biopsies from 20 HIV patients with PPE were studied. The histopathological aspects, cell immunophenotypes, and cytokine expressions in the lesions where quantified and compared to perilesional skin, and to those in the clinically normal skin of HIV patients without PPE-HIV (n=11) and those in normal skin samples from HIV negative individuals (n=10). PPE-HIV occurred mainly in HIV patients with mean CD4+ counts of 124.6 +/- 104 lymphocytes/mm3. Furthermore, their eosinophil counts were significantly increased. The skin lesions were characterized by a predominantly perivascular dermal lymphohistiocytic inflammatory infiltrate. Langerhans cells were normally distributed in the epidermis and seen among the cellular components of dermal infiltrates. The density of CD8+ lymphocytes was elevated and the density of CD4+ cells was reduced in dermal infiltrates. Interleukin 5 was the predominant cytokine in the lesions. Electron microscopic analysis didn't disclose HIV or other infectious agents in the lesions. These results refute the hypothesis of an infectious etiology of PPE-HIV. CD8+ lymphocytes and Langerhans cells seem to have roles in the pathogenesis of PPE-HIV. The increased frequency of IL5 was associated with abundant eosinophils in the lesions, suggesting a type Th2 response in this dermatitis.

Onchocercosis or riverblindness, caused by the filaria ochnocerca volvulus, is endemic in many countries of central and Western Africa. Symptoms of the disease can occur years after the infection, chronic itching dermatitis is the first sign, without treatment blindness may develop after years. Onchodermatitis is a hyperreactive course of onchocercosis with massive eosinophilia and elevated IgE, which suppresses a microfilarial spread through the body. Here, we report about the case of an 9-year-old girl who immigrated from the republic of Congo at the age of seven and has been living in Germany for more than two years. Presumably she suffered from onchodermatitis. She presented papular, indurated and itching skin lesions with pigmentary changes, predominantly located at the limbs. Remarkable results of blood tests were 11,000/microl (60 %) eosinophils and IgE 28 000 KU/l, ECP > 200 mg/l, without a history of atopic diseases. HIV, Strongylosis and Loa Loa were excluded. Anti filaria antibodies were detected in a concentration of 51 AKE, microscopy of skin samples failed to detect the parasites. After a single dose of Ivermectin the dermatitis improved, after two weeks the itching was absent, results of repeated blood tests tend to normalize in the following months. Due to the long lifespan of filaria in humans, the disease occurs years after infection in endemic areas. The differential diagnosis for itching skin lesions with high eosinophils in children from developing countries should include onchocercosis.

Pruritic papular eruption (PPE) is characterized chronic pruritus and symmetric papular eruptions on the trunk and extremities with the absence of other definable causes of itching in an HIV-infected patient. PPE seems to be much more prevalent in less developed regions of the world. The etiology of this distressing condition is unclear, although an inappropriate response to an exogenous agent, such as arthropod bites, may underlie the pathogenesis. Identifying PPE's association with the immune dysregulation of HIV and distinguishing this condition from other pruritic disorders found in HIV-infected patients is important for optimal management.

Trichomoniasis is a common but less well known sexually transmitted infection affecting men and women. In men it is often asymptomatic and goes undetected. In women it can produce a profuse, frothy, unpleasant-smelling vaginal discharge with pruritus and soreness which is sometimes confused with vulvo-vaginal candidiasis (thrush) and bacterial vaginosis. Women often mistakenly treat themselves for thrush with no result. Diagnosis is by laboratory culture and treatment is with metronidazole. Partner notification and treatment should be undertaken. Trichomoniasis often coexists with chlamydia and gonorrhoea. It can have consequences for reproduction, including low birth weight and preterm labour, and has been found to be a co-factor in the transmission of HIV. It is therefore mandatory to ensure prompt and appropriate treatment for all patients diagnosed with trichomoniasis.
