The Professional Medical Journal , 2009,
Abstract: Purpose of Study: To emphasize the role of filtration surgery in the treatment of glaucoma capsulare. Moreover the study also highlights the importance of thorough ocular examination and diagnosis as the condition is likely to be missed. Material, Methods and Results: This study was conducted to find out the results of filtration surgery (trabeculectomy) in such cases. Forty cases with pseudoexfoliation glaucoma presenting in the Dept of Ophthalmology PAF Hospital Mushaf Sargodha were included. These patients were initially treated with topical medications for three months. Thirty cases that showed poor response to drugs were operated upon and a trabeculectomy was performed. Postoperative pressure readings were recorded twice weekly for the first two months and then once monthly for four months. After a follow-up of six months, twenty five cases (83.33%) were effectively controlled without any added medications whereas five cases (16.67%) required addition of a single drug to achieve the desired effect. Conclusion: The response to medical treatment is generally not satisfactory and surgery has to be undertaken as a final resort. Trabeculectomy is the safe and effective operation in glaucoma capsulare (pseudoexfoliation glaucoma).

Mohammad Rafiq Beigh, Mohammad Mustafa, Firdous Ahmad
Circuits and Systems (CS) , 2013, DOI: 10.4236/cs.2013.42020
Abstract:

Quantum-dot cellular automaton (QCA) is an emerging, promising, future generation nanoelectronic computational architecture that encodes binary information as electronic charge configuration of a cell. It is a digital logic architecture that uses single electrons in arrays of quantum dots to perform binary operations. Fundamental unit in building of QCA circuits is a QCA cell. A QCA cell is an elementary building block which can be used to build basic gates and logic devices in QCA architectures. This paper evaluates the performance of various implementations of QCA based XOR gates and proposes various novel layouts with better performance parameters. We presented the various QCA circuit design methodology for XOR gate. These layouts show less number of crossovers and lesser cell count as compared to the conventional layouts already present in the literature. These design topologies have special functions in communication based circuit applications. They are particularly useful in phase detectors in digital circuits, arithmetic operations and error detection & correction circuits. The comparison of various circuit designs is also given. The proposed designs can be effectively used to realize more complex circuits. The simulations in the present work have been carried out using QCADesigner tool.

The Professional Medical Journal , 1999,
Abstract: Pregnant women with positive thyroid peroxides autoantibodies (TPO-Ab) run an increased risk fordeveloping postpartum thyroiditis (PPT). Eighty clinically pregnant women in trimester were screenedfor TPO-Ab titres by radio-immunoassay (RIA) technique and were followed 3-4 months postpartum.During pregnancy TPO-Ab seropositivity was seen in 17.5% cases. Serum thyroxin (T4) and thyroidstimulating hormone (TSH) levels done only in seropositive cases were within normal limits. Afterfollow-up 21.25% cases showed TPO-Ab seropositivity 3-4 months postpartum . The rise in TPO-Abtitre was very significant in 23.5% of seropositive case (5% of the total) who developed mild thyrotoxicphase of PPT. Serum T4 levels were increased above normal limits while serum TSH levels weredecreased in them along with the clinical findings. Twenty nonpregnant women were included in thestudy as controls who were all seronegative for TPO-Ab showing significantly high prevalence of TPOAbduring pregnancy (p<0.001).

Acute management of vascular air embolism
Shaikh Nissar,Ummunisa Firdous
Journal of Emergencies, Trauma and Shock , 2009,
Abstract: Vascular air embolism (VAE) is known since early nineteenth century. It is the entrainment of air or gas from operative field or other communications into the venous or arterial vasculature. Exact incidence of VAE is difficult to estimate. High risk surgeries for VAE are sitting position and posterior fossa neurosurgeries, cesarean section, laparoscopic, orthopedic, surgeries invasive procedures, pulmonary overpressure syndrome, and decompression syndrome. Risk factors for VAE are operative site 5 cm above the heart, creation of pressure gradient which will facilitate entry of air into the circulation, orogenital sex during pregnancy, rapid ascent in scuba (self contained underwater breathing apparatus) divers and barotrauma or chest trauma. Large bolus of air can lead to right ventricular air lock and immediate fatality. In up to 35% patient, the foramen ovale is patent which can cause paradoxical arterial air embolism. VAE affects cardiovascular, pulmonary and central nervous system. High index of clinical suspicion is must to diagnose VAE. The transesophgeal echocardiography is the most sensitive device which will detect smallest amount of air in the circulation. Treatment of VAE is to prevent further entrainment of air, reduce the volume of air entrained and haemodynamic support. Mortality of VAE ranges from 48 to 80%. VAE can be prevented significantly by proper positioning during surgery, optimal hydration, avoiding use of nitrous oxide, meticulous care during insertion, removal of central venous catheter, proper guidance, and training of scuba divers.

Abstract:

Pregnancy and peripartum period leads to Virchow’s triad (hypercoagulability, venous stasis and vascular injury) thereby increasing the risk of thromboembolism by many folds in these patients. Accurate diagnosis of peripartum pulmonary embolism is pertinent for reducing morbidity and mortality. Accurate diagnosis is also vital for avoiding the adverse effects of unwanted anticoagulation in pregnant mother and fetus in a patient wrongly diagnosed with this condition. Computerized tomographic pulmonary angiography has a high specificity and sensitivity in comparison to ventilation/perfusion scan for diagnosis of peripartum pulmonary embolism (PPE). It has a lower fetal radiation exposure and aids in arriving at an alternative diagnosis, if PPE is absent. Low molecular weight heparin is the medication of choice in the treatment of peripartum pulmonary embolism. Thrombolysis is considered in patients with massive PPE and hemodynamic instability, refractory hypoxia or right ventricular dysfunction. Regional anesthesia/analgesia can be given safely in these patients. We report two cases of PPE and review the anesthetic and surgical consideration.
