-Factors affecting human linear growth.

Factors affecting human linear growth.
  • Age
  • Sex
  • Race.
  • Hereditary factors:- Children of two short parents will probably be short and vice versa.
  • Endocrinal factors e.g Growth Hormone which is responsible for stimulation of body growth in humans.
  • Nutritional factors:- Adequate nutrients must be available for normal growth.
  • General health:- Any serious systemic disease in childhood is likely to reduce growth (e.g. chronic kidney disease or chronic infection).
  • Intrauterine growth retardation (small birth weight):-These infants often growpoorly in the long term.
  • Emotional deprivation and psychological factors:- These can impair growth by complex, poorly understood mechanisms.
  • Chromosomal abnormalities.
  • Skeletal maturity.

- Kallmann syndrome.

 Kallmann syndrome


- Def :- It is a rare X-linked recessive genetic disease which characterized by delayed or absent puberty and an impaired sense of smell, also referred as olfactogenital dysplasia.

- Kallmann syndrome is a form of secondary hypogonadism, reflecting that the primary cause of the defect in sex-hormone production lies within the pituitary and hypothalamus rather than a physical defect of the testes or ovaries.

- Kallmann syndrome was described in 1944 by Franz Josef Kallmann, a German-American geneticist.(1)(2)

- Incidence:-
It affects primarily males at an incidence of 1 out of 10,000 in a study of French conscripts.(3)
The male-to-female ratio ranges from 4:1 to 5:1.

- Cause:-
Mutations in the KAL1, FGFR1, PROKR2, and PROK2 genes cause Kallmann syndrome.
These genes play a role in the development of certain areas of the brain before birth. Although some of their specific functions are unclear, these genes appear to be involved in the formation and movement (migration) of a group of nerve cells that are specialized to process smells (olfactory neurons).(4)

- Synonyms:-
  • de Morsier’s syndrome II.
  • Morsier-Gauthier syndrome.
  • Kallmann-de Morsier syndrome.
  • Maestre-Kallmann-de Morsier syndrome.
  • Maestre de San Juan-Kallmann syndrome.
  • Maestre de San Juan-Kallmann-de Morsier syndrome.
  • anosmic hypogonadism.
  • anosmic idiopathic hypogonadotropic hypogonadism.
  • hypogonadotropic hypogonadism and anosmia.
  • hypogonadotropic hypogonadism-anosmia syndrome.

- Pickwickian syndrome.

Pickwickian syndrome

-Def :- It is a condition in which severely overweight people fail to breathe rapidly enough or deeply enough, resulting in low blood oxygen levels and high blood carbon dioxide (CO2) levels.

-Synonyms:- Obesity hypoventilation syndrome(OHS).
-In 1836, Charles Dickens drew in his novel "The posthumous paper of the Pickwick Club" what would be, certainly, the best characterization of an obese subject with respiratory disorders(1).
