Background Type I hypersensitivity reaction to metronidazole and its skin testing are rarely reported. A 69 year old lady had laproscopic cholecystectomy on 27September 2010. Post surgery, IV ciprofloxacin 400mg and metronidazole 500mg were infused at 8.00 pm. Within 30 minutes, she experienced pruritus and noted erythema on her left forearm followed by urticaria over upper limbs and chest. She...

The reaction between normal serum and hyaluronidase has been studied in vitro and under in vivo conditions in skin. Using in vitro conditions of incubation, serum exhibits antihyaluronidase activity as measured by assay of hyaluronidase spreading activity in skin. This confirms the work of others, who have previously described the serum inhibitory factor using other tests of hyaluronidase activ...

Skin tests were made with Type I S.S.S. in 53 cases of Type I pneumococcus lobar pneumonia, 48 of which were treated with antipneumococcus Type I serum. In all but 1 of the 46 recovered cases a positive, immediate skin reaction was obtained at about the time of recovery. In 7 fatal cases reactions were consistently negative, even in the presence of circulating type-specific antibodies. The skin...

In 1908 Neisser applied the principles of the tuberculin test to the diagnosis of syphilis, using extracts of syphilitic organs (Neisser, 191 1). Noguchi (1911) used a suspension of killed cultures of T. pallidum which he called "luetin". While the organ extracts proved more satisfactory than "luetin", the results were unreliable and this original "luetin" test was largely abandoned. Rottmann (...

OBJECTIVE Current guidelines recommend that egg-allergic patients receive an influenza vaccine skin test before the influenza vaccine. This study evaluated the safety of bypassing the skin test and administering graded doses of influenza vaccine to egg-allergic children. METHODS We conducted a retrospective chart-review study of egg-allergic patients aged 6 months to 18 years who received the...

Immunologic processes in diseased human skin have been extensively investigated, but little is known about the effect of skin diseases on human afferent skin lymph. Starting in the papillary dermis, the skin lymphatics drain the adjacent tissue in a one-way flow toward the regional lymph nodes. The composition of the afferent lymph, therefore, reflects the immunologic inflammatory processes in ...

The aim of this study was to examine the effect of serotonin and epinephrine on ion transport of isolated frog skin. The addition of serotonin after incubation in Ringer solution (RH), bumetanide (BUME), and after initial incubation in amiloride and subsequently in RH, reduced hyperpolarization and did not effect the mechanosensitivity of frog skin. Following incubation of the frog skin with am...

Exanthematous reactions with various morphological and localization patterns are the most frequently encountered adverse drug reactions involving the skin. The time course of benign exanthemas typically encompasses a few days to some weeks. They are not complicated by severe systemic symptoms or internal organ involvement. They manifest themselves in a polymorphous manner with primary effloresc...

Skin burns are a rather high incidence lesions which, depending on their depth and extension, can severely affect not only the skin but the entire organism. Third-degree skin burns extended on over 20% of the body surface often require skin graft. Skin allograft is a therapeutic alternative when autograft cannot be used. We investigated the allograft influence on the angiogenesis process in thi...
