1/5. Guttate psoriasis triggered by perianal streptococcal dermatitis in a four-year-old boy.Perianal streptococcal dermatitis (PSD) is a superficial bacterial infection usually with group A beta-hemolytic streptococci. PSD is often misdiagnosed for long periods and patients are subjected to treatments for a variety of differential diagnoses without success. We report a 4-year-old boy with PSD who presented to our clinic with guttate psoriasis for 2 reasons: first, to make dermatologists aware of PSD and second, to emphasize the necessity to examine patients, particularly pediatric patients, with guttate psoriasis very thoroughly and swab both the pharynx and perianal and/or perigenital areas even when they are, or seem to be, asymptomatic for bacterial infections. Once PSD has been diagnosed, systemic antibiotic therapy with penicillin, erythromycin, roxithromycin, or azithromycin (probably augmented by topical mupirocin ointment) should be the treatment of choice. Therapy should be monitored by posttreatment perianal and throat swabs as well as a urine analysis to monitor for poststreptococcal glomerulonephritis.- - - - - - - - - - ranking = 1keywords = bacterial infection (Clic here for more details about this article) |
2/5. Hyperimmunoglobulin E syndrome.Hyperimmunoglobulin E (HIE) syndrome is a primary immunodeficiency disorder characterized by recurrent bacterial infections in presence of very high serum Ig E levels. We are reporting a nine-year-old child with HIE syndrome and reviewing literature on this disease.- - - - - - - - - - ranking = 0.5keywords = bacterial infection (Clic here for more details about this article) |
3/5. Superficial lymphangitis with interface dermatitis occurring shortly after a minor injury: possible involvement of a bacterial infection and contact allergens.BACKGROUND: Linear supralymphatic eruptions with epidermal involvement have rarely been reported. OBJECTIVE: A search was made for apparent anatomical reasons and for external factors to explain the unique distribution pattern and clinical course in three cases in which the linear lesions occurred shortly after a minor injury. methods: Efforts to search for its etiology include careful outlining of the localization, bacterial culture from the site of traumatic injury, patch tests, and skin biopsies. RESULTS: Linear lesions developed along superficial lymphatic vessels and the presence of eczematous conditions around the injured sites and isolation of staphylococcus aureus from the site were observed concomitantly. The histopathological findings showed interface dermatitis. CONCLUSION: Our cases provide a unique example of the combined effects of a bacterial infection and contact allergens in the development of the linear supralymphatic eruptions.- - - - - - - - - - ranking = 2.5keywords = bacterial infection (Clic here for more details about this article) |
4/5. Inherited deficiency of the third component of complement associated with recurrent pyogenic infections, circulating immune complexes, and vasculitis in a Dutch family.A family is described in which 3/11 children showed a homozygous deficiency of C3, and both parents and six other children had subnormal levels of C3. The three children with selective C3 deficiency suffered repeatedly from bacterial infections, whereas the parents and the other siblings were clinically healthy. During infectious episodes the patients showed a maculopapular skin rash, and at such times immune complexes were present in the serum. biopsy specimens of the skin lesions showed the picture of leukocytoclastic vasculitis.- - - - - - - - - - ranking = 0.5keywords = bacterial infection (Clic here for more details about this article) |
5/5. An id reaction to mycobacterium leprae: first documented case.We present a case of generalized sarcoidal dermatitis in a patient with tuberculoid leprosy. After careful consideration of the reactional states in leprosy and recognizing that id reactions occur in other mycobacterial infections, we concluded that the patient's eruption was likely an id reaction to his mycobacterium leprae infection. It was most reminiscent of the tuberculids: lichenoid tuberculid and lichen scrofulosorum. However, its histomorphologic appearance was distinctive, showing elongated granulomata along with foci of incipient perineural granuloma formation, similar to the histomorphologic appearance of tuberculoid leprosy. A pathogenetic mechanism for this unique eruption is reviewed briefly.- - - - - - - - - - ranking = 0.5keywords = bacterial infection (Clic here for more details about this article) |
