Purpose of the study: To which of the ACR sonographic BIRADS lexicon descriptors can be used reliably to differentiate benign from malignant solid breast masses. Objectives: 1.Main Objective: To determine the association of sonographic ACR BI-RADS descriptors and solid breast masses 2. Specific Objective: To determine the predictive probabilities of sonographic BI-RADS lexicon descriptors Methodology: This was a 15 months prospective cross sectional study in which 125 consecutive patients who met the inclusion criteria were enrolled. The study was carried out at theAga KhanUniversity hospitalradiology department between October 2008 and December 2009 inclusive. The scans were performed in ourradiology department by residents and consultant radiologists. The sonographic BI-RADS descriptors were then assigned to the lesions based on the consensus arrived at between the principal investigator and the consultant radiologist. The findings were then correlated with the histological/cytological diagnosis which was the gold standard. The study was approved by the University Research and Ethics Committee Results: 66% (n=82) of the patients turned out to have benign lesions while 34% (n=43) had malignant breast lesions. All the sonographic BI-RADS descriptor variables demonstrated significant association with the histology results apart from vascularity. The predictive probability of malignancy was lowest (8.36 %) for lesions with parallel orientation and well circumscribed margins and highest (73.89%) for masses with non parallel and poorly circumscribed margins. Conclusion: There is a significant association between all the sonographic ACR BI-RADS lexicon descriptors and solid breast masses apart from one descriptor: vascularity. Lesions with both non parallel orientation and non circumscribed margins have the highest predictive probability for malignancy.

غزل

 

لمس کی پوروں پہ تھی جو حکمرانی بیچ دی،

آج اس کی آخری ہم نے نشانی بیچ دی۔

 

ہم نے قصداً اپنے غم سے بے خبر رکھا تمہیں،

جو تمہارے تک پہنچتی وہ کہانی بیچ دی۔

 

لے کے جاتی تھی ہمیں اجداد کی قبروں پہ جو،

ہم نے گاؤں کی وہ پگڈنڈی پرانی بیچ دی۔

 

اب تم آؤ گے تو ہر جذبہ ملے گا منجمد،

ہم نے دریائے محبت کی روانی بیچ دی۔

 

کون ہوتا زیر بارِ کاغذ و دست و قلم،

واردات-قلب و جاں ہم نے زبانی بیچ دی۔

 

کر گئ خوشبو بھی آخر سارے رشتے کالعدم،

ہم نے جب وہ موتیا، وہ رات رانی بیچ دی۔

 

اب کہاں مہمان بن کے ہم رہیں طاہر وحید،

اہل دل نے اپنے دل کی راجدھانی بیچ دی

Demography and Pakistan

Demography, along with geography, has always figured in the making of nations and in inter-state relationships. But perhaps never so critically as in the case of Pakistan. Indeed, in all the annals of its proto-history and existential career, demography and Pakistan have been interminably entwined. This may sound incredible, even inexplicable.

Assessment of Socialization Strategies Adopted by Public and Private Sector Universities of Punjab

The research was designed to assess and compare the organizational socialization strategies adopted by public and private sector universities of Punjab for its employees. The major objectives were to explore the socialization strategies that can be applied in the universities; to assess the effect of the socialization strategies being used by the universities of Punjab; to compare the socialization strategies being adopted by public and private sector universities and further to propose the comprehensive model by keeping in view the cultural background of Pakistan to enhance socialization practices. The population of the research was based on 9397 faculty members hired by the Higher Education Commission (HEC) recognized universities of Punjab, Pakistan. By considering public and private sectors as separate strata proportional stratified sampling technique was applied to draw representative sample. 10 percent of the faculty members from both strata were selected as the sample of the study. That data was collected by the use of three different tools (Socialization Strategies Scale (SSS), Socialization Content Learning Scale (SCLS) and Socialization Practice Suggestion) developed in the light of the model presented by Ruth V. Aguilera, John C. Dencker and Zeynep Y. Yalabik (2006). The data was analyzed with the help of SPSS 16th edition. Results revealed that the socialization strategies used at organizational (β = -.023 & R2 = .003), group (β = -.068 & R2 = .004) and individual level (β = -.069 & R2 = .001) were inversely related with Socialization Content Learning and were not being used effectively. However in the prevailing situation the private sector universities were utilizing socialization strategies more frequently then the public sector. Yet the socialization content learning was found better in public sector employees. On the basis of findings it was recommended that socialization of the employees must be accorded the foremost priority by the organizations’ leadership and the top level management of the universities. Special focus may be retained on the provision of orientation, mentoring, and social activities. There is a need to develop a culture and attitude to share, communicate, support and discuss professional issues and matters.
