بدعنوانی کے خاتمے میں معاشرے کا کردار

بدعنوانی کے خاتمے میں معاشرے کا کردار
کوئی چیز بھی اللہ تعالیٰ نے بے مقصد پیدانہیں فرمائی ، ہر چیز کی تخلیق میں کوئی نہ کوئی غرض و غایت ضرور کارفرما رہی ہے، لیکن انسان چونکہ ظلوما ًجہو لا کے مصداق تخلیق کردہ اشیاء میں کوئی نہ کوئی تبدیلی کا مرتکب ہوتا رہتا ہے اور اس چیزکی تخلیق کا جوعظیم مقصد ہے وہ پس پردہ چلا جا تا ہے۔ اور یوں کائنات کی رنگینیوں ، رعنائیوں اور دل آویزیوں کے آفتاب نصف النہار کو گرہن لگ جاتا ہے۔ کسی چیز کی اصل ہیئت کو تبدیل کرنے کا نام بدعنوانی ہے۔
مجاہد سرحدپر بجائے حفاظت کے جاسوسی کررہا ہے تو یہ بدعنوانی ہے۔ معلم مسند تدریس پرمتمکن ہو کر تشنگان علم کی پیاس بجھانے میں تساہل اور غفلت کا شکار ہے تو یہ تدریسی بدعنوانی ہے۔ مسیحاجب اپنے پیشے سے وفا نہیں کر رہا اور اس کے زیرعلاج مریض کے مرض میں اضافے کا سبب اس کی نا اہلی اور نا تجر بہ کاری ہے تو یہ گھناؤنا جرم اور کرپشن ہے۔ جس معاشرے میں ابتداء سے لے کر انتہاء تک بدعنوانی ہی بد عنوانی ہو اس معاشرے کی فضاء میں محو پرواز طائر خوش الحان بھی اپنی پرواز کوتا دیر قائم نہیں رکھ سکتا۔ ایسے معاشرے کی مسموم فضاء اس کے تنزل کا باعث بنتی ہے۔
ہم اگر بد عنوانی اور کرپشن کے خلاف قدم نہیں بڑھائیں گے تو اس کی جڑیں طول پکڑتی جائیں گی اور پھر اس ناسور پر نشتر چلانے کے لیے تا دیر ہوم ورک کرنا پڑے گا۔ اس مرغِ بسمل کی طرح تڑپاتے ہوئے زہر ہلا ہل کے لیے کسی تریاق کی اشد ضرورت ہے۔
آج ضرورت اس امر کی ہے کہ ہر شعبہ سے تعلق رکھنے والاشخص اس کومنطقی انجام تک پہنچانے کے لیے کمر بستہ ہوجائے ، صحافی اپنے اخبار...

Iron deficiency and risk of oral squamous cell carcinoma Iron expression in oral carcinoma

Oral squamous cell carcinoma (OSCC) is a subset of head and neck squamous cell carcinoma caused by excessive substance abuse like alcohol, tobacco etc.  Objectives: Aim of the present study was to evaluate the iron expression in different grades of OSCC and potential of iron staining as a prognostic marker and its importance as an essential nutrient in diet. Methods and Patients: It was a cross sectional study.A total of 40 oral biopsies were evaluated and the mean age of patients was 53.5 years with age range 23-80 years. 14 cases were well differentiated, 14 moderately differentiated and there were 12 poorly differentiated case. Iron staining was performed for all these cases. Results: Iron positivity was observed in 11 (27.5%) of OSCC patients with maximum iron positivity in well differentiated group (64.28%) of age range 20-40 years (70%). More patients had tongue as site of cancer. There was no genderwise difference in iron expression. Iron deficiency was associated with poor prognosis indicating iron as an important nutrient which can prevent OSCC if adequately present in our routine diet. Conclusions: Prevalence of iron positivity in young patients and initial stage of OSCC, indicates the protective effect of iron against oral squamous cell carcinoma

Vitamin D Levels in Black African Adults at the Aga Khan University Hospital Nairobi

Introduction: Vitamin D has been known for centuries for its benefits in bone health. Recent observational studies have however demonstrated its benefits in infectious diseases such as tuberculosis and non-communicable diseases such as diabetes mellitus, cardiovascular diseases and cancer. This has led to a dramatic increase in testing among adults. The cut-offs for vitamin D deficiency have been debated for decades and the current cut off is derived from a Caucasian population. Studies done among black African adults in Africa are few and have shown that vitamin D deficiency ranges from 5-91%. In view of the difference in skin colour, latitude and vitamin D binding protein, these values might be misleading. A few cut- offs have correlated vitamin D deficiency to physiological markers such as parathyroid hormone (PTH), calcium and phosphate with varying results. Objectives: This study was carried out to determine the proportion of healthy black African adults at AKUHN who were classified as 25(OH)D deficient using the current cut-off of 20ng/ml and to correlate this with markers of physiological deficiency, dietary intake of vitamin D rich foods and sunshine exposure. Methods: This was a cross sectional study carried out among blood donors at AKUHN from March to May 2015. Blood was taken from consecutively recruited participants who gave informed consent and filled a questionnaire. Vitamin D levels were assayed and correlated with PTH, calcium and phosphate. Results: A total of 258 individuals were recruited for the study. The proportion of study participants who had a 25(OH)D level of <20ng/ml thus classified as vitamin D deficient was 17.4% (95% C.I 12.73-22.07). The 25(OH)D level that coincided with a significant increase in PTH was 30ng/ml. There was no statistically significant difference in calcium and inorganic phosphate levels between Vitamin D deficient and non-deficient individuals (U=3788 p 0.06, U=4299 p 0.499). vi Males were less likely to be vitamin D deficient (O.R 0.48 (C.I 0.233-0.993) p 0.04). Sunshine exposure for ≥3 hours reduced the odds of being Vitamin D deficient though this was not statistically significant after multivariate regression analysis. The use of sunscreen and dietary intake of oily fish didn’t reduce the odds of one being vitamin D deficient. Conclusion: This study highlights the prevalence of vitamin D deficiency in a healthy black African population based on a widely adopted cut off. Given that calcium and phosphate levels didn’t differ between vitamin D deficient and non-deficient individuals, the appropriateness of
