Arcanobacterium haemolyticum associated with pyothorax: case report

Arcanobacterium haemolyticum has an established role in the etiology of human pharyngitis. There are increasing reports of systemic infections caused by this organism. From India, we report the first case of Arcanobacterium haemolyticum causing pyothorax in an immunocompetent adolescent male patient. The probable mode of infection is also discussed. The role of A. hemolyticum as an animal pathogen needs further study

Remaining idle time aware intelligent channel bonding schemes for cognitive radio sensor networks

Channel bonding (CB) is a technique used to provide larger bandwidth to users. It has been applied to various networks such as wireless local area networks, wireless sensor networks, cognitive radio networks, and cognitive radio sensor networks (CRSNs). The implementation of CB in CRSNs needs special attention as primary radio (PR) nodes traffic must be protected from any harmful interference by cognitive radio (CR) sensor nodes. On the other hand, CR sensor nodes need to communicate without interruption to meet their data rate requirements and conserve energy. If CR nodes perform frequent channel switching due to PR traffic then it will be difficult to meet their quality of service and data rate requirements. So, CR nodes need to select those channels which are stable. By stable, we mean those channels which having less PR activity or long remaining idle time and cause less harmful interference to PR nodes. In this paper, we propose two approaches remaining idle time aware intelligent channel bonding (RITCB) and remaining idle time aware intelligent channel bonding with interference prevention (RITCB-IP) for cognitive radio sensor networks which select stable channels for CB which have longest remaining idle time. We compare our approaches with four schemes such as primary radio user activity aware channel bonding scheme, sample width algorithm, cognitive radio network over white spaces and AGILE. Simulation results show that our proposed approaches RITCB and RITCB-IP decrease harmful interference and increases the life time of cognitive radio sensor nodes

Foreign-body reaction due to incorrect injections of allergen extracts containing aluminum hydroxide gel

WOS: 000230181200008Background. - Subcutaneous allergen immunotherapy is considered as effective and safe in allergic patients. Although mild local cutaneous reactions occur frequently, the development of persistent nodules at the in injection site is I rare event, We describe a case with unusual persistent nodular reactions at the sites of previous immunizations incorrectly performed via the intradermal route, Case. - A 42-year-old female presented with multiple persistent lesions on both forearms that appeared after allergen immunotherapy. Immunotherapy with an aluminum hydroxide-adsorbed mite extract had been started 3 years earlier. Prescription of immunotherapy and injections of the extract were performed in a rural private medical facility, under the supervision of a physician with nospecial allergy training, injections had been given erroneously intradermally rather than subcutaneously. Physical examination revealed multiple reddish, indurated cutaneous nodules at the injection sites. The diagnosis of a foreign-body granulomatous reaction was confirmed by histological examination of the lesions. Conclusions. - Intradermal injections of aluminum hydroxide-containing allergen extracts should be strictly avoided, This case emphasizes published international recommendations according to which specific allergen immunotherapy should be prescribed only by allergy specialists in order to avoid unsuitable indications and methods that can sometimes result in serious side effects.

Psoriasiform contact dermatitis due to propolis in a beekeeper

WOS: 000228578300014PubMed ID: 15875534Background: More than 250 cases of allergic contact dermatitis due to propolis have been described. A few of these occurred in beekeepers. Objective: To describe a case of psoriasiform dermatitis caused by propolis in a beekeeper who thought that his lesions were related to honeybee stings. Methods: A 45-year-old beekeeper experienced hand dermatitis for the past 5 years. He believed that the lesions occurred and worsened when he was stung by honeybees. He was prescribed topical corticosteroids several times, but because he was stung frequently, the drugs never helped control the lesions. In the past few years, he frequently had contact with propolis during honey collection, but he denied the role of propolis because he was wearing gloves while handling the beehives. For diagnostic evaluation, skin biopsy, skin prick tests (SPTs), identification of specific IgE antibodies, and atopic patch tests were performed. Results: Skin biopsy showed psoriasiform contact dermatitis. Results of SPTs to honeybee and serum specific I-E for Apis mellifera remained negative. Results of the atopic patch test performed using A mellifera SPT material were also negative in the first 20 minutes and on the second and third days. However, propolis showed a positive erythematopapular reaction on day 2. The patient never again worked as a beekeeper, and neither did he, as far as he knew, use any medical or cosmetic products that contained propolis. His hand lesions improved almost completely. Conclusion: Dermatitis due to propolis should never be disregarded in beekeepers, and every effort should be put forth to make a correct diagnosis and to convince the patients of the cause

Analysis of pulmonary hydatidosis according to their segmentary locations

The objective of this analysis is to compare the pulmonary locations of lung hydatid cysts and their size with respect to their locations with available literature. The records of 82 patients who were operated for pulmonary hydatid cysts between January 2001 and December 2005 were retrospectively evaluated. One hundred eleven cysts detected in 82 patients were placed into 2 groups as those located in the right lung (group A, 55 cysts) and those located in the left lung (group B, 56 cysts), and the segments involved were investigated. The gender distribution of the patients was 40 male and 42 female, with a mean age of 35.2 ± 17.64 years (range: 7-82 years). No difference was detected with respect to involvement between the 2 lungs (P = 0.285). The most commonly involved segment was the posterior basal segment of the lower lobe with 15 cysts (27.3%) from group A and 20 cysts (35.7%) from group B. No involvement of the lower lobe medial basal and anteromedial basal segments was observed. The most common surgical procedures applied were cystotomy and capitonnage. The findings of the study showed that pulmonary hydatidosis were located in some segments of the lungs more frequently, primarily in the posterior segment of the lower lobe and the apicoposterior segment of the upper lobe. In addition, the higher prevalence of giant cysts in the lower lobe and their ability to produce symptoms only after being enlarged suggest a role of mechanisms other than elasticity of the lungs. © 2008 Lippincott Williams & Wilkins, Inc
