The Perined-Hoftiezer birth weight curves show the optimal birth weight (and its distribution) of children born at the corresponding gestational age. The curves are differentiated by gender. Identifying small children is important for reducing mortality and morbidity. These curves are based on data from the perinatal registration of newborns in the Netherlands. The curves are normative and therefore developed based on a low-risk population without known risk factors for fetal growth restriction. All multiple pregnancies, inductions, and primary cesarean sections were also excluded to approximate the optimal birth weight for each gestational age. More information can be found at www.perined.nl and in the following scientific publications: Hoftiezer L et al. Am J Obstet Gynecol. (2019) From population reference to national standard: new and improved birthweight charts. 10.1016/j.ajog.2018.12.023 Hoftiezer L et al. Eur J Pediatr. (2016) Defining small-for-gestational-age: prescriptive versus descriptive birthweight standards. 10.1007/s00431-016-2740-8 The curves were compiled by Liset Hoftiezer, guided by a working group consisting of representatives from various professional groups, birth care organizations, and researchers: Joyce Dijs-Elsinga, Jeroen van Dillen, Michel Hof, Marije Hogeveen, Chantal Hukkelhoven, Karline van de Kamp, Richard van Lingen, Alieke de Roon-Immerzeel, Rosalinde Snijders, Viki Verfaille, Ger de Winter, and Koos Zwinderman.

Write and send prescriptions, easily, quickly and anywhere in the world. The RX whizz app offers doctors and healthcare professionals who are legally authorized to write prescriptions the ability to write and send prescriptions that comply with all legal requirements quickly and conveniently from any location. You only need to enter your own doctor's details and signature once. The app remembers all previous data entered and thus easily builds a handy list of all your patients and prescribed medicines. When entering data, the app automatically presents an alphabetical list of all previously entered data. This saves you a lot of time. All entered data will only be stored in the app on your own phone or tablet and will not be sent to our server and cannot be seen by other apps. So your data is safe. Created recipes are not sent to our server nor stored within the app. This guarantees complete security and privacy. You send the created prescription via your own e-mail to the patient, to your assistant or directly to the pharmacy.
