1.Comparison of cerebral angiography and transcranial doppler sonography in ischemic stroke
Ho Chi Minh city Medical Association 2003;8(4):203-206
At the Department of internal neurology of Cho Ray Hospital from Dec 2000 to Jan 2003. 130 patients with acute hemisphere cerebral ischemic stroke were studied. Among them, 34 patients could not evaluated by transcranial Doppler sonography, only 79 had transcranial Doppler sonography (TDS) results and MRI results, which confirmed cerebral infarctus. TDS found 30 normal cases, 28 cases with asymmetric indices reduced, 18 cases increased, 1 case of localized acceleration, 2 cases of obstructive cerebral artery in the side of clinical symptom. MRI found 17 normal cases, 62 cases of stricture of cerebral arteries. Sensitivity and specificity of TDS accounted for 74.2% and 82.4% in comparing with cerebro-vascularogramme made by MRI.

Surgical sperm retrieval (SSR) is currently one of the most common procedures in in vitro fertilization (IVF). However, a gap between the guidelines and routine clinical practice regarding antibiotic use in SSR, which might lead to antibiotic resistance, is a challenging problem worldwide. A cross-sectional survey was conducted from May 1, 2021, to July 15, 2021, to investigate antibiotic usage by medical professionals when performing SSR in IVF centers in Vietnam. The confidential questionnaire comprised 12 items, including characteristics of the study population, awareness of antimicrobial resistance, attitude toward prescribing antibiotics, and current practice of prescribing antibiotics when performing SSR. Surveys were completed by 30 of 45 registered IVF centers (66.7%). Among 67 physicians working at those centers, the age and work-experience years (mean ± standard deviation [s.d.]) were 38.6 ± 6.6 years and 11.2 ± 7.0 years, respectively. Over 60% of them held a degree in Obstetrics and Gynecology, and over four-fifths were men. Most respondents "often/very often/always" raised awareness of antimicrobial resistance to their patients (83.3%), but only half of them "often/occasionally" prescribed antibiotics to patients with SSR in cases where the prescription would be optional. About one-tenth of respondents followed the recommendation from the American Urological Association using "prophylaxis only" for SSR patients. For more invasive SSR, physicians tended to prescribe more complicated and sometimes inappropriate regimens. In conclusion, antibiotic usage in SSR was not always appropriate among IVF centers. Further studies may define specific recommendations for regimens, intervention strategies, and programs to promote appropriate antibiotic use for SSR patients among IVF specialists.
