Cataract |
"A cataract is an opacity or clouding that develops in the crystalline lens of the eye or in its capsule." [HPO:probinson] |
Note that some ophthalmologists call any opacity in the lens a cataract, while others restrict the term to lens opacities that impair vision. We use the term to refer to the first meaning (any lens opacity). |

Global developmental delay |
"A delay in the achievement of motor or mental milestones in the domains of development of a child, including motor skills, speech and language, cognitive skills, and social and emotional skills. This term should only be used to describe children younger than five years of age." [DDD:hvfirth, HPO:sdoelken] |
Developmental retardation is any significant lag in development in the any or all of the physical, cognitive, behavioral, emotional, or social spheres. Note that the term intellectual disability (mental retardation) refers to not merely a delay in development but rather a permanent limitation. Note that the term 'psychomotor retardation' is also used in some contexts to refer to a slowing of thought and physical movements as a result of major depression or intoxication. |

Thrombocytopenia |
"A reduction in the number of circulating thrombocytes." [HPO:probinson] |
Thrombocytopenia can be divided into three major causes; 1) low production of platelets in the bone marrow; 2) intravascular breakdown of thrombocytes; and 3) increased turnover of platelets in spleen or liver (extravascular). |

Triphalangeal thumb |
"A thumb with three phalanges in a single, proximo-distal axis. Thus, this term applies if the thumb has an accessory phalanx, leading to a digit like appearance of the thumb." [HPO:probinson, PMID:19125433] |
The requirement for a single PD axis relates to the issue that partial forms of Preaxial polydactyly may comprise a partially duplicated thumb with two distal phalanges and a single proximal phalanx. That finding is instead coded as a mild form of thumb polydactyly. Note that this finding can be readily assessed by examination and/or physical manipulation of the thumb. |

Intrauterine growth restriction is a newer term that is preferred over Intrauterine growth retardation. The causes of IUGR include maternal abnormalities (chronic hypertension, cyanotic heart disease, smoking, drug abuse), placental or umbilical cord abnormalities (including placenta previa and cord anomalies), maternal medicationas, and genetic disorders of the fetus. |

Abnormality of the hypothalamus-pituitary axis |
"Abnormality of the pituitary gland (also known as hypophysis), which is an endocrine gland that protrudes from the bottom of the hypothalamus at the base of the brain. The pituitary gland secretes the hormones ACTH, TSH, PRL, GH, endorphins, FSH, LH, oxytocin, and antidiuretic hormone. The secretion of hormones from the anterior pituitary is under the strict control of hypothalamic hormones, and the posterior pituitary is essentially an extension of the hypothalamus, so that hypothalamus and pituitary gland may be regarded as a functional unit."

Dolichocephaly |
"An abnormality of skull shape characterized by a increased anterior-posterior diameter, i.e., an increased antero-posterior dimension of the skull. Cephalic index less than 76%. Alternatively, an apparently increased antero-posterior length of the head compared to width. Often due to premature closure of the sagittal suture." [HPO:probinson, PMID:19125436] |
Cephalic index is the ratio of head width expressed as a percentage of head length. The normal range is 76-80.9%. Head length is measured between the glabella (the most prominent point on the frontal bone above the root of the nose) and the most prominent part of the occiput in the midline, using spreading calipers. Head width is measured between the most lateral points of the parietal bones on each side of the head, using spreading calipers. Cephalic index standards are derived from Caucasians and have limited relevance for other races and ethnicities. Current norms have limited validity because of changes in infant sleeping position and consequent changes in head shape. New data should be developed. Dolichocephaly is distinct from Prominent occiput, but both can be present in the same individual and should be coded separately. Scaphocephaly is a subtype of dolichocephaly where the anterior and posterior aspects of the cranial vault are pointed (boat-shaped). |
