rickets
Let an agent explain rickets and its causes in general terms from clinical and public health sources, describe signs, prevention and treatment, distinguish nutritional from inherited forms and from osteomalacia, and route personal questions to clinicians.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain rickets and its causes in general terms from clinical and public health sources, describe signs, prevention and treatment, distinguish nutritional from inherited forms and from osteomalacia, and route personal questions to clinicians.
A disease of growing children in which bones soften and deform because of failed mineralisation, most often from vitamin D deficiency due to lack of sunlight and diet, and also from calcium deficiency, inherited disorders such as hypophosphataemic and vitamin D-dependent rickets, and kidney disease, presenting with bowed legs, the rachitic rosary of rib swellings and delayed growth; rickets is preventable with vitamin D and calcium, has resurged in some populations, and also affects animals such as poultry, while the adult equivalent is osteomalacia.
What it is for: Not applicable; a disease.
It can be explain causes and forms; relay signs and prevention; relay treatment approaches; route personal questions.
Distinguishing features
Growing bone affected
Vitamin D and calcium causes
Preventable
Inherited forms
What it looks like
Not a visible object; bowed legs, swollen wrists and rib beading in affected children.
Physical character
vitamin D supplement for infants: 400 IU per day - common guidance
historical prevalence in industrial cities: majority of children share - early twentieth century, as reported
How it is recognised
Childhood bone mineralisation disease
Nutritional, hypocalcaemic, hypophosphataemic and vitamin D-dependent rickets
Osteomalacia is the adult form; osteogenesis imperfecta is a different bone disease

What the second pass must settle
- Should hypophosphataemic rickets be a separate entry?
- How should guidelines be linked?
- The registry entry has merged aliases naming signs, forms and an animal disease; should they be split off?
