Study of Serum Homocysteine and Vitamin B12 levels in Eclampsia, Pre-Eclampsi...Internet Medical Journal
The present study was carried out to evaluate the occurrence of association between homocysteine, and vitamin B12 in patients with Preeclampsia , Eclampsia and those with history of previous PIH. 30 such patients from obstetric ward were studied for estimation of serum homocysteine, and vitamin B12 over a period of Jan10 to Jun 2011. Serum homocysteine and vitamin B12 were determined by means of Immulite 1000 analyzer. The statistical analysis of study group of preeclampsia compared with normotensive control group, showed significant alterations in serum homocysteine, and vitamin B12 concentrations in preeclampsia and eclampsia group. Inverse association between serum homocysteine and vitamin B12 levels were observed in preeclampsia and eclampsia. The present study found hyperhomocysteinemia and deficiency of vitamin B12 along with increased blood pressure as a risk factor in preeclampsia. Final outcome of these patients after Inj Vitamin B12 therapy has improved at par with control group without any neonatal or maternal mortality in all four groups
This document discusses the proper design of clinical trials in radiology. It reviews key aspects of designing a research study such as defining the research question, reviewing existing literature, determining the appropriate study design, defining the study population and variables, and ensuring precise and accurate measurements. Proper design is important for valid assessment of diagnostic tests. Some key points discussed are that the research question should be important, novel, feasible to answer, ethical, and relevant, and that diagnostic methods are commonly evaluated using randomized blinded trials.
The healthcare crisis in the US is exacerbated by a shortage of physicians, especially primary care physicians. The number of physicians needs to increase to meet the growing and aging population's demand. One solution is to increase medical school enrollment. Larger class sizes could lower tuition costs and reduce medical student debt, encouraging more to enter primary care. With more physicians, especially primary care doctors, healthcare access and quality could improve while costs decrease through increased competition and prevention focus.
This document summarizes a study comparing the effectiveness of intrauterine insemination (IUI) versus fallopian tube sperm perfusion (FSP) for treating non-tubal infertility. The study included 200 patients undergoing a total of 404 stimulated cycles. Patients were randomly assigned to receive either standard IUI using 0.5 ml of sperm (184 cycles) or FSP using 4 ml of sperm injected into the fallopian tubes (220 cycles). The clinical pregnancy rate was significantly higher in the FSP group at 21.81% per cycle compared to 11.95% for the IUI group. The authors conclude FSP is more effective than standard IUI for treating non-tubal infertility.
This document provides a summary of several medical journal articles and studies. Some key findings include:
- Manual removal of the placenta 10 minutes after delivery reduces hemodynamic compromise compared to 15 minutes.
- A 1 mmol/L reduction in LDL cholesterol appears to reduce major vascular events by about 11 per 1000 people over 5 years.
- Occipital nerve stimulation appears to be a safe and effective treatment for chronic migraine and medication overuse headache.
- Singletons from IVF/ICSI have higher risks of obstetric and perinatal complications than spontaneous conceptions.
The document summarizes key principles regarding professional behavior and ethics for physicians. It discusses appropriate boundaries in physician-patient relationships, informed consent, medical errors and liability, and obligations to report issues like abuse or impaired colleagues. Physicians must prioritize patient welfare, maintain open communication, and follow standards of care to practice ethically and avoid legal issues.

The document summarizes recent news and research in the medical field. It reports that contrary to a recent article, becoming a primary care physician is not currently a "hot career track" due to difficulties finding employment. It also notes that physician salary averages do not include some groups like residents. The summary recommends allied health careers like nursing which have similar pay but lower costs of education. Recent research findings are also presented briefly on various medical topics.
Physician incomes have declined in the 1990s due to cost containment measures and the rise of managed care. Younger physicians face high student loan debt and repayment schedules, limiting their practice options. Managed care has reduced physician earnings, especially for specialists. The emphasis on primary care physicians and cost containment has put pressure on referrals and physician advocacy for patients. Rising medical school tuition and costs combined with diminished earnings potential has turned students away from specialization and lowered expectations for lucrative careers. Overall physician incomes are expected to continue declining as more generalists work for managed care organizations.
This document summarizes several medical studies published in medical journals. It reports on studies that found: blood pressure measurements taken in a doctor's office should not be disregarded; talking can raise blood pressure readings; lowering cholesterol with lovastatin reduces heart attack risk; strength training benefits cardiac rehab patients; morphine does not increase risk of missed appendicitis diagnoses; increased cardio-respiratory fitness lowers diabetes risk; psychoactive drug websites are most popular in the pharmaceutical industry; passive smoking increases coronary heart disease risk; and the Duke treadmill score predicts mortality. It also provides fast facts on suicide statistics in the United States.
The US News and World Report article is out of touch with current health care job market trends. It ignores the difficulty primary care physicians face finding jobs and provides misleading average salary figures by excluding some physician groups. The hot career track in health care is now allied health professions like nurse practitioners which have nearly identical income but require less time and money to become. Recommended reading includes the novel A Confederacy of Dunces for its humor and Anatomy of an Illness by Norman Cousins, a must-read for doctors. Music for the Mozart Effect Vol. 2 is also recommended for its proven healing powers.
Vice President Gore discussed plans to increase cancer research funding by 65% over 5 years. Documents also revealed that tobacco companies targeted 14-24 year olds in advertising campaigns in the 1970s. A conference suggested the organism Chlamydia Pneumonia may be partially responsible for asthma progression in some individuals. The US remains divided on abortion 25 years after Roe v Wade.
The document summarizes recent medical studies and reports. It notes that a British Medical Journal report found that people are walking 22% less today than in 1972, with the greatest decline among 5-15 year olds, attributed to increased automobile use. It also mentions a Lancet study of a patient whose intractable hiccups were apparently cured by smoking marijuana. The document provides brief summaries of additional recent medical studies on topics like asthma treatment, preventing heart attacks, sex differences after heart attacks, osteoporosis treatment, treating anal fissures, preventing heart attacks and strokes, and unnecessary antibiotic prescriptions.
This weekly medical newsletter summarizes recent studies on a variety of health topics. Key findings include: polyunsaturated fats may increase breast cancer risk while monounsaturated fats decrease it; breastfeeding should be delayed for an hour after vigorous exercise; and dextromethorphan cough medicines should be avoided during pregnancy due to animal studies finding birth defects. The newsletter also reports on studies relating to SIDS risks from infant quilts, benefits of second opinions before elective surgery, and effects of supplements like rhubarb fiber and green tea.
1) The document provides one sentence summaries of recent medical studies and articles to direct readers to the source material, but notes this information does not constitute medical advice.
2) Studies discussed found breastfeeding and reducing dust mite exposure can decrease childhood allergies; over 40% of children are exposed to secondhand smoke at home; and estrogen replacement therapy combined with etidronate was more effective at increasing bone mass than either alone.
3) Other research mentioned found increased anxiety was associated with increased coronary heart disease risk; oral clindamycin reduced preterm ruptured membranes; and father involvement improved cognitive outcomes in preterm infants.
- A study of over 1,000 clinical pearls and medical summaries found that continuous combined hormone replacement therapy achieved amenorrhea in 90% of women, fish oil lowered blood pressure and triglyceride levels, and vitamin D deficiency was highly prevalent among elderly patients. Full measles vaccination and proper interpretation of tuberculosis tests were also discussed.
The document contains summaries of multiple medical articles posted between May 20, 2004 and June 7, 2004. The articles discuss a variety of topics including: screening recommendations for ovarian cancer; potential cancer risk reductions from statin drugs; exercise and fitness programs; community health initiatives; prostate cancer risks from selenium levels; heart disease in women; treadmill testing recommendations; and nuclear cardiology research presentations.
1) Despite advances in antibiotics, death rates from infections have increased 58% from 1980 to 1992, partially due to HIV. Pneumococcal pneumonia is becoming increasingly resistant to antibiotics.
2) Studies found that a high dietary fiber intake and fish oil supplements can decrease the risk of heart disease, while coffee and beta carotene supplementation alone do not affect heart disease risk.
3) Early treatment of strokes and heart attacks within 1-4 hours improves outcomes, while smoking and not taking aspirin after a heart attack increases risks. Dog ownership may benefit heart attack survival.
The document provides a summary of recent medical articles in one sentence summaries. It notes that the summaries provide medical information and not advice, and readers should consult their physician before making changes based on the information. The summaries cover topics like smoking cessation methods, risk factors for various diseases, effectiveness of treatments and vaccines, and lifestyle factors that impact health.
Intrauterine insemination versus fallopian tube sperm perfusion in non tubal ...Internet Medical Journal
Background: Controlled ovarian hyper stimulation (COH) combined with intrauterine insemination (IUI), using a volume of 0.5 mail of inseminate is commonly offered to couples with non tubal infertility. Another method is Fallopian tube sperm perfusion (FSP) which is based on a pressure injection of 4 ml of sperm suspension while attempting to seal the cervix to prevent semen reflux. This technique ensures the presence of higher sperm density in the fallopian tubes at the time of ovulation than standard IUI. The aim of this study was to compare the efficiency of IUI and FSP in the treatment of infertility.
Methods: 200 consecutive patients with infertility in 404 stimulated cycles were included in the study. Those randomized to standard IUI included 100 patients in 184 cycles [158 Clomiphene citrate/human menopausal gonadotrophin cycles and 26 Letrozole/FSH cycles exclusively for polycystic ovarian disease patients] (group A). Patients subjected to FSP included 100 patients in 220 cycles (193 Clomiphene citrate/human menopausal gonadotrophin cycles and 27 Letrozole/FSH cycles exclusively for polycystic ovarian disease patients] (group B). Swim up semen preparation technique was used in all cases. Insemination was performed in both groups 34-37 hours after hCG administration. Standard IUI was performed using 0.5 ml of inseminate. In FSP 4ml inseminate was used.
Results: In group A (184 IUI cycles in 100 patients), 22 clinical pregnancies (presence of gestational sac with fetal cardiac activity) occurred (11.95% per cycle over four cycles). In group B, (220 cycles of FSP in 100 patients), 48 clinical pregnancies occurred (21.81%per cycle over four cycles) and this difference was statistically significant (p<0.05).
Conclusions: For non-tubal sub fertility, the results indicate clear benefit for FSP (Fallopian tube sperm perfusion) over IUI (Intrauterine insemination).
Key Words: Intrauterine insemination, Fallopian tube sperm perfusion, Non-tubal infertility.
