    Background: Gastroesophageal reflex is known as an acid reflex, is long term condition where stomach contents back into the oesophagus resulting in either symptoms or complications. GERD disease is caused by weakness or failure of the lower oesophageal sphincter. Symptoms include the acidic taste behind the mouth, heart burn, chest pain, difficult breathing and vomiting. Complication includes esophagitis, oesophageal strictures and barrettes oesophagus. Objective: The aim of this research was to introduce the symptoms of GERD disease in asthmatic patients and how these symptoms worsen the symptoms of asthma disease and what clinical pictures present with the asthmatic disease. Methodology: A designed performa was used to collect the data and after filling the performa, results were drawn and conclusion through the facts and the information given by patients. Results: In the present study among all 164 asthmatic patients, 70 (42.7%) patients showed dyspepsia, 58 (35.4%) were with chest burning, 23 (14%) were asking about chest pain, with acidic mouth taste were 39 (23.8%), 22 (13.4%) were feeling sore throat and 44 (26.8%) showed regurgitation reflex. Among these 164 patients 16 (9.8%) were smokers and 148 (90.2 %) were non-smokers. 47 (28.7%) were males and 117 (71.3%) were females. Conclusion: It is concluded that gastroesophageal reflux disease in asthmatic patients present symptoms of acidic mouth taste, chest burning, chest pain, dyspepsia, regurgitation reflex and sore throat

    OBJECTIVE: To compare harmonic scalpel (HS) tonsillectomy with electrocautery (EC) tonsillectomy in terms of operating time, intra-operative blood loss, post-operative pain and secondary haemorrhage.METHODS: Sixty adult patients subjected to tonsillectomy only, were evaluated in this prospective study. The patients were stratified into 2 groups (30 each) based on the dissecting instrument used (HS vs. EC) at Aga Khan University Hospital Karachi Pakistan from June, 2006 to August, 2008.RESULTS: The mean operative time was less in electrocautery group (EC 3.57 +/- 0.85 minutes Vs HS 4.20 +/- 1.37 minutes;

    If all of the top levels of security fail, the final and most critical tier, data security, must not fail. By breaching this layer of defence, the CIA's triad principles of confidentiality, integrity, and availability are undermined. However, increasing security reduces the performance of the system and usability. This paper addresses the fundamentals of cloud computing as well as its key challenge: security. This paperexamines a variety of cryptographic methods used by major cloud providers. It proposes an alternative algorithm for encrypting data in transit from the user to the cloud in order to ensure data security and defend against Man-in-the- Middle (MitM) attacks like sniffing. The paper concludes by urging further study into the proposed cryptography algorithm in order to ensure data protection and privacy in all three data states

    Goldenhar Syndrome (GS), also known as oculo-auricular vertebral syndrome, is a congenital defect that occurs in 1 of 5,000 births characterized by the underdevelopment of the ears, soft palate, lip, and mandible due to an anomaly of the first and second branchial arches. Hepatoblastoma is the most common primary liver tumor in the pediatric population. However, it is still considered a rare malignancy because liver cancers only account for 1% of childhood cancers. Most children with hepatoblastoma are asymptomatic, however we describe a 2-year-old girl with Goldenhar Syndrome diagnosed with hepatoblastoma after experiencing abdominal pain and constipation. Findings from the case can further support the argument for an association between Goldenhar Syndrome and hepatoblastoma

    How did bad weather and a chance observation of what was most likely a failed experiment, lead to the Nobel-prize winning discovery of radioactivity? In this article, the author narrates the story of Henri Becquerel’s experiments with uranium salts, describing a series of scientific investigations that arose to understand an unexpected and unusual observation, originally made by this physicist

    Today social transformation is fast as evident in many parts of the world. It has triggered changes in functional dynamics of many professions. Teaching is one such profession. Teachers are assuming greater responsibilities with changing time and carving their niche once again to face challenges of present time. In our country such changes have been primarily driven by economic growth and technological advances especially in post 1990s. With liberal economic policy Indian society has witnessed increased upward social mobility. It has impacted the young generation in different ways. Teachers not only perceive their role changing, but have developed mechanisms to cope with this situation. It is against this background that an effort has been made through this article to get a brief understanding of role and challenges of teachers in contemporary Indian society
