Dengue Fever-Triggered Malignant Hyperthermia.

Malignant hyperthermia (MH) is a genetic skeletal muscle disorder characterized by hypermetabolic crisis usually triggered by anesthetic drugs. Non-anesthesia-triggered or awake MH is rare or under-reported. Other than anesthetic drugs, identified common triggers are exercise, fever, and viral infection.

Fetal Doppler reference values in women with a normal body mass index.

Objectives: To construct gestation specific reference limits for fetal umbilical (UA), middle cerebral artery (MCA) pulsatility indices (PI) and the cerebroplacental ratio (CPR) in singleton pregnancies with normal BMI between 16 and 40 weeks of gestation.

Methods: We ultrasonographically examined 596 fetuses from women with normal nutritional and health status and minimal environmental constraints on fetal growth. Each mother was considered only once for measurement of fetal Doppler indices, at gestations between 16 and 40 weeks in a prospective cross-sectional study.

Symphysis-pubis fundal height charts to assess fetal size in women with a normal body mass index.

Objectives: To construct symphysis-pubis fundal height (SFH) charts to estimate fetal size in pregnant women with a normal body mass index (BMI) and to describe the variation of SFH measurements according to BMI.

Methods: cross sectional study was carried out at Ampara and Gampaha Districts in Sri Lanka. Women with normal nutritional and health status, normal BMI and minimal environmental constraints on fetal growth, with ultra sound confirmation of dates by fetal crown-rump length measurements between 11 weeks and 13 weeks + six days,had their SFH measured, using non-elastic tape and standard techniques, between 24 and 41 weeks gestation.

Use of ultrasound in predicting success of intrauterine contraceptive device insertion immediately after delivery.

Objectives: To assess by ultrasound examination the success of insertion of an intrauterine contraceptive device (IUD) immediately after delivery and to determine the optimal distance between the lower end of the IUD and the internal os in predicting successful retention of an IUD.

Methods: This was a prospective study carried out between December 2012 and April 2013. Two ultrasound examinations, transabdominal and transvaginal, were performed prior to hospital discharge following delivery and again at 6 weeks following delivery in women who received a postpartum IUD.
