High enthusiasm about long lasting mentoring relationships and older mentors.

BACKGROUND: Mentoring plays a pivotal role in workplace-based learning, especially in the medical realm. Organising a formal mentoring programme can be labor and time intensive and generally impractical in resource constrained medical schools with limited numbers of mentors. Hence, informal mentoring offers a valuable alternative, but will be more likely to be effective when mentors and protégés share similar views. It is therefore important to gain more insight into factors influencing perceptions of informal mentoring. This study aims to explore mentors and protégés' perceptions of informal mentoring and how these vary (or not) with gender, age and the duration of the relationship. METHOD: We administered an Informal Mentor Role Instrument (IMRI) to medical practitioners and academics from Egypt, Pakistan and Saudi Arabia. The questionnaire was developed for the study from other validated instruments. It contained 39 items grouped into 7 domains: acceptance, counselling, friendship, parenting, psychological support, role modelling and sociability. RESULTS: A total of 103 mentors and 91 protégés completed the IMRI. Mentors had a better appreciation for the interpersonal aspects of informal mentoring than protégés, especially regarding acceptance, counselling and friendship. Moreover, being older and engaged in a longer mentoring relationship contributed to more positive perceptions of interpersonal aspects of mentoring, regardless of one's role (mentor or protégé). CONCLUSION: It can be concluded that the expectations of mentors and protégés differed regarding the content and aim of the interpersonal characteristics of their mentoring relationship. We recommend mentors and protégés to more explicitly exchange their expectations of the informal mentoring relationship, as typically practiced in formal mentoring. Additionally, in our study, seniority and lasting relationships seem crucial for good informal mentoring. It appears beneficial to foster lasting informal mentoring relationships and to give more guidance to younger mentors.

Circulating chemokine eotaxin and chemokine receptor CCR3 in allergic patients.

Eotaxin is a chemokine with a selective eosinophil chemoattraction and its receptor is the chemokine receptor CCR3. The presence of CCR3 on Th2 lymphocytes is of particular interest. This work was performed to evaluate circulating level of chemokine eotaxin and CCR3 expression in allergic patients. It included 60 patients [23 (38.3%) with asthma, 20 (33.4%) with allergic rhinitis and 17 (28.3%) with skin allergy] and 12 controls. The level of plasma eotaxin & CCR3 expression on CD4+ T cells were determined by ELISA & flowcytometry respectively. Both plasma eotaxin level and expression of CCR3 on CD4+ T cells were higher in allergic patients than controls in different types of allergy. In conclusion, plasma eotaxin concentration is a candidate biological marker for the evaluation of allergic diseases.

Correlations between clinical and laboratory findings in patients investigated for aspergillosis.

We investigated 120 patients suspected clinically to have pulmonary aspergillosis with different clinical manifestations "aspergilloma (Subgroup A), allergic bronchopulmonary aspergillosis (Subgroup B) and invasive pulmonary aspergillosis (Subgroup C)" and correlated between their clinical and laboratory findings and endogenous specific aflatoxin production. They were subjected to isolation of Aspergillus strains, measurement of serum total IgE and specific Aspergillus IgG by ELISA and identification of aflatoxin producing Aspergillus strains using fluorescence analysis of spectroline. Aspergillus was isolated from 45 patients (37.5%). Subgroup A had a negative statistically non-significant correlation between clinical and laboratory findings as regard total IgE and for Aspergillus IgG (only haemoptysis &weight loss had significant correlation with aspergillus IgG). Subgroup B & Subgroup C had positive, statistically significant correlation &negative statistically non significant correlation respectively as regard all clinical findings and both total IgE & serum IgG. This study also showed that 6 Aspergillus strains out of 45(13.3%) produced endogenous aflatoxin. It is concluded that a significant correlation that exists between clinical and serological findings in allergic pulmonary aspergillosis. Aflatoxins may be produced in vivo by strains of Aspergillus and may result in manifestations similar to those caused by ingestion of aflatoxin in food.
