Th1 cell development induced by cysteine proteinases A and B in localized cutaneous leishmaniasis due to Leishmania guyanensis

The cysteine proteinases CPA and CPB from Leishmania major induced Th1 responses in patients with leishmaniasis due to Leishmania guyanensis. Furthermore, cysteine proteinases induced neither interleukin 4 (IL-4) nor IL-13 and low levels of IL-10 in controls and patients. The results suggest that CPs would be quite good candidates for a vaccine against different Leishmania species.     

Ambient air pollution and emergency department visits among children and adults in Casablanca,Morocco

This study presents the relationships between ambient air pollutants and morbidity and emergency department visits among children and adults performed in Great Casablanca, the most populated and economic region in Morocco. This research was analyzed using conditional Poisson model for the period 2011–2013. In the period of study, the daily average concentrations of SO₂, NO₂, O₃ and PM₁₀ in Casablanca were 209.4 µg/m³, 61 µg/m³, 113.2 µg/m³ and 75.1 µg/m³, respectively. In children less than 5 years old, risk of asthma could be increased until 12% per 10 µg/m³ increase in NO₂, PM10, SO₂ and O₃. In children over 5 years and adults, an increase of 10 µg/m³ air pollutant can cause an increase until 3% and 4% in respiratory consultations and acute respiratory infection, respectively. Similarly, impact on emergency department visits due to respiratory and cardiac illness was established. Our results suggest a not negligible impact on morbidity of outdoor air pollution by NO₂, SO₂, O₃, and PM₁₀.

Online health communities,contributions to caregivers and resilience of older adults

The aim of this paper is twofold. Firstly, to investigate the potential benefits of online health communities (OHCs) for informal caregivers by conducting a systematic literature review. Secondly, to identify the relationship between the potential benefits of OHCs and resilience factors of older adults. Performing a thematic analysis, we identified the potential benefits of OHCs for informal caregivers of older adults, including two salient themes: (a) caregivers sharing and receiving social support and (b) self and moral empowerment of caregivers. Then, we uncovered how these potential benefits can support resilience of older adults. Our findings show that sharing and receiving of social support by informal caregivers, and self and moral empowerment of informal caregivers in OHCs, can support four resilience factors among older adults, including self-care, independence, altruism and external connections. This review enables a better understanding of OHCs and Gerontology, and our outcomes also challenge the way healthcare and aged-care service providers view caregivers and older adults. Furthermore, the identified gap and opportunities would provide avenues for further research in OHCs.     

Primitive intracranial ependymomas. Salah-Aza?z institute experience]

PURPOSE: - To assess the outcome and prognostic factors of patients with primitive intracranial ependymomas treated at the department of radiotherapy of Salah-Aza?z Institute. METHODS AND MATERIAL: - Between 1972 and 1997, 31 patients aged one to 53 years received postoperative radiotherapy. There were 16 males and 15 females. Location of tumor was infratentorial in 24 cases and supratentoriel in seven cases. Surgical treatment consisted of complete resection in 14, incomplete resection in 13 and unknown type in four patients. All patients were treated with radiotherapy to the craniospinal axis in 26 cases, whole brain in five cases. RESULTS: - Five years survival rate was 63%. For infratentorial tumors, two patients failed locally, two patients failed locally and at distance and four patients failed only at distance, while one patient with supratentorial tumor relapsed locally. Age, performances status, tumor site, gender and extent of surgery had no impact on survival. The treatment field extent was the only variable predictive of outcome. Patients treated with craniospinal irradiation had a survival rate of 86% compared with 37,5% for patients treated with whole brain irradiation. CONCLUSION:- Infratentorial ependymomas seem to have a worse prognosis than supratentorial ones. Irradiation field extent should be correlated to prognostic factors.     

Primary intramedullary ependymomas: retrospective study of 16 cases]

PURPOSE: To review the radiotherapy department experience in treating primary spinal cord ependymomas (PSCE), analyse prognostic factors and provide treatment recommendations regarding literature review. MATERIALS AND METHODS: Sixteen patients with PSCE received postoperative radiotherapy between 1972 and 1997. There were 10 male and 6 female patients with a mean age of 34 years (range 2-63). Surgery was gross total resection in 2 cases, subtotal resection in 9, biopsy in 4 and of unknown type in one patient. All patients were treated with radiotherapy to the craniospinal axis (4 cases), spinal cord (1 case) and to the site of primary tumour in 11 cases. RESULTS: Five year-survival rate was 73%. Two patients had recurrent tumours within the primary site. Gender, extent of surgery and treatment field extent were not prognostic factors. Histologic type was the only variable predictive of outcome. Patients with myxopapillary type had a 5-year survival rate of 100% compared with 47% for those with other histology types. CONCLUSION: We conclude that aggressive surgery is not necessary in the management of PSCE, localised field radiotherapy is associated with favourable outcome, and tumour grade is an important prognostic factor.
