Purpose: to compare umbilical artery and middle cerebral Doppler ultrasound values in normal and high risk pregnancies with fetal outcome. Method: 121 consecutive pregnancies (at or over 28 weeks gestation), stratified into low and high risk pregnancies based on clinician information were prospectively examined with doppler ultrasound of UA and MCA. Results: outcome was available for 100 of the 121 patients. 26% of pregnancies had poor outcome. Of these 73% (19) and 27% (7) were classified as high risk and low risk respectively. UA alone or in combination with MCA was shown to have 100% specificity for predicting fetal outcome. However, sensitivities and negative predictive values were poor, ranging from 8-21% and 17-35% respectively. Better positive predictive values were registered in MCA in comparison to those of UA (PPV of 44% and 83% in high risk and low risk categories respectively versus PPV of 0% in both UA high and low risk categories respectively). However, MCA specificities were lower at 80% and 85% for high and low risk pregnancies respectively. Conclusion: the combination of UA and MCA doppler ultrasound examinations is very specific in predicting fetal outcome. However, the sensitivities, positive and negative predictive values were low.

ملک فہد بن عبدالعزیز

آہ ! پاسبان حرم ملک فہد
یکم اگست کو دنیائے اسلام پر یہ خبر بجلی بن کر گری کہ ملک فہد بن عبدالعزیز سعودی حکومت کا تاج و تخت چھوڑ کر اس ملک الملوک کی بارگاہ کبریا میں پہنچ گئے جس کے ملک و سلطنت کو کبھی زوال نہ ہوگا اور وہ ہمیشہ قائم و باقی رہے گا، کل من علیھا فان ویبقیٰ وجہ ربک ذوالجلال والاکرام۔ [الرحمن:۲۶۔۲۷]
وہ ۱۹۹۵؁ء ہی سے بیمار چل رہے تھے، ان کی معذوری کی وجہ سے حکومت کا کاروبار بڑی حد تک ان کے بھائی اور ولی عہد عبداﷲ بن عبدالعزیز انجام دینے لگے تھے، اس سال ملک فہد کی بیماری نے شدت اختیار کرلی تو ۲۷؍ مئی ۲۰۰۵؁ء کو ریاض کے خاص شاہ فیصل اسپتال میں علاج کے لیے داخل ہوئے، مرض میں تخفیف و اضافہ ہوتا رہتا تھا، آخر یکم اگست بروز دوشنبہ داعی اجل کا پیغام آگیا، اناﷲ وانا الیہ راجعون۔
عالم اسلام اور پوری دنیا کے مسلمان ان کے انتقال سے غم زدہ اور سوگوار ہیں، ان کی ذات بڑی فیض بخش تھی، اور ان کے دریائے کرم اور جودوسخا کی بارش عام تھی، اس لیے ان کے غم میں سب کی آنکھیں اشک بار ہیں، ع عمت فواضلہ فعم مصابہ
اب ان کے بھائی عبدالعزیز نے حکومت کی باگ ڈور سنبھال لی ہے، اور لوگوں نے ان سے بیعت کرلی ہے، انہوں نے اپنے بھائی سلطان بن عبدالعزیز کو ولی عہد مقرر کیا ہے جو اس وقت تک دفاع اور سیاحت کے وزیر تھے، اﷲ تعالیٰ ان کو اپنی بھاری ذمہ داری اٹھانے کی قوت دے اور ان کی مدد کرے، ملک فہد کی تدفین منگل کے روز ۲؍ اگست کو ہوئی جس میں دنیا کے اکثر ملکوں کے سربراہوں اور نمائندوں نے شرکت کی، ہندوستان سے بھی ایک وفد جنازے میں شریک ہوا تھا۔

Sero-Prevalence & Disease Pattern of Ppr Peste Des Petits Ruminants Infection in Small & Large Ruminants Buffalo, Cattle and Camel and Molecular Characterization of Isolates Circulating in Sindh Province of Pakistan With Their Economic Impact

A participatory epidemiological (PE) study was carried out in the Tharparkar District of Sindh province, Pakistan, which is the only fertile desert in the world. The study was carried out to assess the association of the disease with animal production systems and its socio-economic impact. During participatory rural appraisal activities, sets of semi structured interviews, visualization techniques, ranking and scoring techniques were applied to collect qualitative and quantitative data. The study revealed that sheep and goat are reared without systemic housing. The average herd size was 30 head with a sheep and goat ratio of 1:2. Women have an important role in sheep and goat husbandry especially for feeding, watering, milking, and management of lambing/ kidding. It was concluded from the study that most low-income landless farmers are involved in sheep and goat raising, which played a significant role in their household economy and provided the main source of income. It was also accomplished that Peste des Petits Ruminants and other prevailing sheep and goat diseases are causing momentous negative impacts on food security and child nutrition with the enduring impacts including delays in marriages, postponement of surgery and other family health interventions as well as disruption of children education.
