Autism- Towards Comprehensive Assessment And Management, Ayesha Mian 2017 Aga Khan University Hospital Karachi,pakistan

Autism- Towards Comprehensive Assessment And Management, Ayesha Mian

Ayesha Mian

Autism is a pervasive, neurodevelopmental disorder characterized by stereotyped movements and impairment in social skills and communication patterns. Prevalence patterns show an increasing burden of about 1 in 150 children affected by the disorder. Most affected individuals have symptoms that interfere greatly with quality of life. Although a burgeoning concern, research on the prevalence, etiological factors and presentation patterns is limited in LAMI countries, leading to a minimal understanding of the disorder at individual, professional and societal level. There is an urgent need to enhance awareness and education to decrease stigma that maybe associated with autism.

The Effect Of Photoactivated Tmp On Burkholderia Cepacia Biofilms, Reyna G. Osorio, Chandra N. Swiech, Tracy L. Collins 2017 Cedarville University

The Effect Of Photoactivated Tmp On Burkholderia Cepacia Biofilms, Reyna G. Osorio, Chandra N. Swiech, Tracy L. Collins

Tracy Collins, Ph.D.

Burkholderia cepacia is an opportunistic pathogen that causes infections in immunocompromised individuals such as cystic fibrosis patients. B. cepacia infections are typically characterized by the formation of complex communities of cells known as biofilms. Because B. cepacia biofilms are difficult to eradicate using antibiotics, it is important to pursue alternative treatment methods. Photodynamic therapy (PDT) is a type of therapy that uses light, a photosensitizer, and oxygen to elicit cell death through the production of reactive oxygen species. PDT has been shown in previous studies to be successful in killing both Pseudomonas aeruginosa and Staphylococcus aureus. In this study, we ...

E,E-Farnesol Inhibits Swarming Motility In Burkholderia Cepacia Through Rhamnolipid Production, Stephanie E. Nicholls, Alayna N. Sanderson, Andrea P. Schwartz, Lauren E. Ward, Jessica N. Weisensee, Molly Yandrofski, Tracy L. Collins

Tracy Collins, Ph.D.

Burkholderia cepacia and Candida albicans both exhibit cell-to-cell communication through the use of quorum-sensing molecules (QSM) known as autoinducers. E,E-farnesol is a QSM produced by C. albicans which regulates its conversion from yeast to mycelium. Because there is a positive correlation between the presence of B. cepacia and C. albicans in the lungs of individuals with cystic fibrosis (CF), we examined whether E,E-farnesol had an effect on swarming motility in B. cepacia. Swarming motility was inhibited when B. cepacia was exposed to 250 µM of E,E-farnesol. In addition, there was a 26.8% decrease in rhamnolipid production ...

Acute massive pulmonary embolism is a life-threatening emergency that must be promptly diagnosed and managed. A 52-year-old man presented with progressively increasing dyspnoea for three days. He had a previous history of chronic obstructive pulmonary disease and was currently a heavy smoker. Examination revealed bilateral wheezing. Chest x-ray and electrocardiography showed non-specific changes. The patient was initially treated as a case of chronic obstructive pulmonary disease exacerbation secondary to pneumonia. However, despite optimum medical management, his oxygen saturation deteriorated. Emergent computed tomography scan of chest showed bilateral massive pulmonary emboli. As the patient's haemodynamic status rapidly deteriorated, cardiothoracic surgery ...

Right Ventricular Perforation: A Rare Complication Of Pulmonary Artery Catheterization, Khalid Ahsan, Mohammad Hamid, Saulat H. Fatimi, Ijaz Hidayat

Saulat Fatimi

A 70 years old male underwent Coronary Artery Bypass and Graft (CABG) surgery. After induction, a Pulmonary Artery Catheter (PAC) was inserted via right IJV with some difficulty in achieving PA tracing. During distal RCA anastomosis, surgeon noticed PAC tip coming out of Right Ventricular (RV) surface. Resistance was felt on trying to pull PAC, so it was left there. Cardiac surgeon then opened the Right Atrium (RA) and pulled out the catheter. Multiple attempts during insertion of PA catheter should always raise the suspicion of PAC tip slipping back into the RV. It should be closely monitored during surgery ...

Abstract Endocarditis is characterized by vegetations, which is a mass of platelets, fibrin, micro-colonies of micro-organisms, and inflammatory cells, in the endocardium. Over the past three decades, the incidence of right-sided endocarditis has risen dramatically in Pakistan. We report a 36-year woman with a history of repeated intravenous analgesic injections for low back pain, presenting with high grade fever, sepsis and a white cell count of 44,000 with 90% neutrophils. Echocardiography showed large mobile vegetations on TricuspidValve (TV). Tricuspid Valve Endocarditis (TVE) is generally responsive to medical treatment; however, about 25% of TVE patients require surgical intervention. Long-term survival ...

Tracheal Reconstruction For Comlex Acute Tracheal Stenosis, Saulat H. Fatimi, M.Qasim Raza, Alina Ghani, Nilay Shah, Awais Ashfaq

Saulat Fatimi

Tracheal stenosis refers to a reduction in the size of the tracheal lumen and can be due to a myriad of reasons, but the most common remains trauma. In iatrogenic situations, internal trauma is the most likely culprit, resulting from prolonged intubation. Our case reviews a patient who developed severe tracheal stenosis (90% reduction in lumen size) within a month of a threeday- long intubation, and presented to the emergency room with dyspnea, orthopnea, and stridor. Tracheal reconstruction with resection of the stenosed segment and end-to-end anastomosis was done. The patient returned a month later with re-stenosis, and underwent tracheal ...

Successful Resection Of Lymphangioma Of The Neck And Mediastinum Presenting As Stridor In A 12 Year Old Child, Babar Irfan, Maha Tahir, Omar Irfan, Hamza Abdur Rahim Khan, Saulat H. Fatimi

Saulat Fatimi

Lymphangiomas are congenital malformations of lymphatic tissue. This benign condition is generally found in the neck region and is discovered by 2 years of age. Here we report the case of a 12 year old child who presented with a cervical and mediastinal cystic hygroma that had progressed to such a space occupying nature as to cause the shifting of the trachea. The entire mass was successfully resected with a lower neck incision. Our case suggests the necessity of considering cystic lymphangioma in the differential diagnosis of lateral neck masses and use of adequate imaging to substantiate the preoperative diagnosis.

Primary Melanotic Schwannoma With Typical Histology, Usman B. Mahmood, Fazal Wahab Khan, Benish Fatima, Muhammad Usman Tariq, Saulat Hasnain Fatimi

Saulat Fatimi

Abstract We present a case of a 17-year male with a soft tissue density spreading from the neural foramina (T3) of the spinal cord and involving the right upper thoracic cavity. We managed the patient through surgical intervention and resected the complete tumor. Gross definition and microscopic findings of the resected tissue revealed the definitive diagnosis of melanotic schwannoma. The histological characteristics in this case were very specific and harbour an important diagnostic clue for this rare disease. Malignant melanoma was ruled out on the basis of histological findings. The patient recovered completely and was healthy on one-year follow-up.

Hydatid disease is a frequently encountered entity in endemic areas and constitutes a serious health problem. The lung is the second most commonly affected organ after the liver. In three of four cases of pulmonary hydatid cyst, the cyst is solitary. The early phase after primary infection is always asymptomatic. Primary symptoms in patients with pulmonary cystic echinococcosis include cough, fever, and chest pain. The clinical and radiological manifestations for the hydatid cyst in the lung depend on the integrity of the cyst. Bronchial fistulization is an important event in the evolution of the cyst. In cases of dubious orientation ...

Saulat Fatimi

The prevalence of aortic aneurysms is 3-4% in individuals more than 65 years. Age and haemodynamic factors play an important role in the development of aortic aneurysms. Most patients with aortic aneurysms are asymptomatic at the time of discovery. Thoracic aneurysms are usually found incidentally after chest radiographs or other imaging studies. The most common complications of thoracic aortic aneurysms are acute rupture or dissection. Some patients present with tender or painful nonruptured aneurysms. Patients are thought to be at increased risk for rupture and should undergo surgical repair on an emergent basis We document a case of a 66-year-old ...

Giant Pulmonary Bulla With Mediastinal Shift In A 12 1/2 Year Old Girl, Saulat H. Fatimi, Asif Jafferani, Awais Ashfaq

Saulat Fatimi

Pulmonary bulla in children represent interesting entities. Mostly congenital bronchopulmonary foregut malformations and acquired cysts like pneumatocoeles have also been described. We present a case of a 12 1/2 years old girl with acute onset respiratory distress symptoms harbouring a huge pulmonary cyst exhibiting mass effects, resulting in mediastinal deviation. Following initial workup, cyst excision was carried out which revealed presence of fungal hyphae that was susceptible to Fluconazole therapy post operatively. The case points out how a pulmonary cyst can present in older children with symptoms of respiratory distress and mass effects.

The aorta is a large blood vessel that carries blood from the heart to the rest of thebody. The aortic root consists of the aortic valve and the openings for thecoronary arteries (the coronary ostia). An aortic aneurysm is an abnormal bulgein the wall of the aorta. If an aneurysm develops in the aortic root, the aorta candilate and the aortic valve can leak. If the aneurysm continues to expand, it canrupture and can cause life-threatening internal bleeding.Aneurysms of the aortic root are often due to degenerative disease of media.Aneurysm of the aortic root often affects patients in ...

Enteric Cyst In The Left Posterior Mediastinum Mimicking A Hydatid Cyst On Chest Computed Tomography Scan, Shazib Sagheer, Abdul Malik Amir Humza Sohail,, Yousaf Bashir Hadi,, Saulat H. Fatimi

Saulat Fatimi

Abstract Mediastinal enteric cysts are a rare occurrence among adults and are usually asymptomatic. In most cases they are an incidental finding in the right hemi-mediastinum and are associated with vertebral anomalies. We report the unusual case of a 23 year old male who had a mediastinal mass on chest X-ray as an incidental finding. Chest Computed Tomography (CT) scan revealed no vertebral anomalies and a cystic mass in the left posterior mediastinum with features similar to those of a hydatid cyst.Posterolateral thoracotomy was done and the cyst was excised. Histopathology report revealed it to be an enteric cyst.
