Community acquired pneumonia: risk factors associated with mortality in a tertiary care hospitalized patients
OBJECTIVE: To evaluate risk factors associated with mortality in patients hospitalized with CommunityAcquired Pneumonia (CAP) from a developing country.
METHODS: An observational study was conducted on adult patients admitted with a diagnosis of CAP from January 2002 to August 2003 at Aga Khan University hospital, Karachi, Pakistan. Clinical records were reviewed for demographic characteristics, clinical and laboratory features, hospital course, and risk factors associated with mortality.
RESULTS: A total of 329 patients (187 males) were admitted with CAP. Two-third of patients had underlying co-morbid medical illnesses. Complications developed in 15.7% cases and the overall mortality rate was 11%. Risk factors were identified on initial clinical assessment, laboratory and radiological features and during hospital course. On admission elevated blood urea, new onset of confusion, abnormal liver function test, low serum albumin, cardiomegaly and presence of underlying malignancy were strongly associated with increased mortality. Failure to respond to therapy was associated with a high risk of mortality as depicted by complication during hospital stay (Odds Ratio = 23.3, 95% Confidence Interval = 10.3-52.8), need for mechanical ventilation (OR = 17.1, 95% CI = 7.4-39.8) and need for intensive care unit (OR = 9, 95% CI = 4.2-19.3).
CONCLUSIONS: Abnormal liver function test, low albumin and presence of cardiomegaly were more significant mortality risk factors than age, respiratory rate and blood pressure. Elevated blood urea and confusion remain strong risk factors on admission. Failure of response to therapy and onset of complications heralded a high risk of death
Isolated non-compaction of left ventricular myocardium
Isolated non-compaction of the left ventricle is a distinct form of cardiomyopathy. It may be idiopathic or secondary to an identifiable disease. The condition usually presents with symptoms of cardiac failure. The present report is of a child with this disease who was diagnosed at birth and was relatively stable at 5 years of age
Assisted reproductive technology : experience with IVF/ICSI
Objective: To analyze success rates of assisted reproduction techniques ART (IVF/ICSI) in couples experiencing subfertility, and factors which may help in predicting treatment outcome.Design: A prospective cohort follow-up study.PLACE AND DURATION OF STUDY: Study was conducted at Concept Fertility Centre, Karachi, between July 1, 2000 and December 31, 2002.SUBJECTS AND Methods: A cohort of 310 couples undergoing 330 in-vitro fertilization (IVF) and intra cytoplasmic sperm injection (ICSI) cycles were followed for treatment outcomes. Predictor variables included age of women, cause of subfertility, drug regimen used for ovulation induction, day of embryo transfer, and ease of embryo transfer. While outcome variables included rates of fertilization, pregnancy, live birth, miscarriages, multiple pregnancies and ovarian hyperstimulation syndrome (OHSS).Results: The overall pregnancy rate was 35.2 %, while takehome live-birth rate was 25.1%. Treatment cycles which were done for male factor only, had higher probability of success as compared to female factors or for unexplained infertility. Patients who underwent transvaginal ovum pick up and embryo transfer (TVOPU + ET) had an overall pregnancy rate of 29.4% as compared to those who underwent frozen embryo transfer (FET) cycles (22.6%). There was no statistically significant difference between pregnancy rates for ovulation induction with recumbent FSH (rFSH) and HMG (32.7% v 33.6%, p-value 0.87). Quality of embryo transfer was significantly better (33.7%, v 24.2%, p-value 0.042) in patients who conceived.CONCLUSION: Our results are comparable in terms of pregnancy rates, live birth rates and complication rates, to the results reported in international literature. We however, need more data from centres in Pakistan for future reference and research
