PURPOSE To measure the association between the menstrual cycle and the frequency of alveolar osteitis (AO). MATERIALS AND METHODS In a study with a single-blind design, patients with bilateral impacted third molar teeth underwent randomized surgical extraction: one tooth during the menstrual period and one during the middle of the cycle. The postoperative examiner was unaware of the menstrual...

Population aging coupled with heightened consumerism among those using the health care system have increased public and research interest in menopause. Despite these trends, we know little about the process of menstrual cessation. This paper reviews previous claims regarding secular trends in menopausal age by considering how menstrual cessations differ by type: (1) that due to surgical interve...

Reported last menstrual period (LMP) is commonly used to estimate gestational age (GA) but may be unreliable. Ultrasound in the first trimester is generally considered a highly accurate method of pregnancy dating. The authors compared first trimester report of LMP and first trimester ultrasound for estimating GA at birth and examined whether disagreement between estimates varied by maternal and...

An accurate assessment of gestational age is vital to population-based research and surveillance in maternal and infant health. However, the quality of gestational age measurements derived from birth certificates has been in question. Using the 2002 US public-use natality file, the authors examined the agreement between estimates of gestational age based on the last menstrual period (LMP) and c...

BACKGROUND The best method of gestational age assessment is by ultrasound in the first trimester; however, this method is impractical in large field trials in rural areas. Our objective was to assess the validity of gestational age estimated from prospectively collected date of last menstrual period (LMP) using crown-rump length (CRL) measured in early pregnancy by ultrasound. METHODS As part...

Thirty-eight-year-old lady, mother of two children, came to OPD with history of cyclic pain in the perineal region which was gradually increasing in intensity and duration for 1 year. Pain was intense in last 4 months. Pain was related to her menstrual cycles. She also gave history of itching over perineal region. She delivered her first child 10 years back with right mediolateral episiotomy fo...

BACKGROUND/AIM Definition of menstrual migraine as a specific clinical entity or, maybe, migraine headache with menstrually related occurring, still remains unresolved question. The aim of this study was to investigate if perimenstrual headache in our patients fulfills diagnostic the International Classification of Headache Disorders (ICHD) criteria for migraine without aura or represents a dif...

BACKGROUND When an ultrasound-based estimate of gestational age (GA) is less (greater) than an estimate based on a definite last menstrual period, the fetus may grow slower (faster) than average. While the association between these discrepancies in GA estimates and adverse perinatal outcomes has been examined extensively, there is scant evidence about long-term effects, such as child neurodevel...
