Growth and Growth Hormone through the Ages: Art and Science.

BACKGROUND: People have long been fascinated with the size and growth of living things, from the giants of classic mythology and art to the little people who also have appeared in classical art, as well as the courts of European monarchs, and were exploited in "shows." Serious medical evaluation began in the late 19th century with the description of acromegaly and its association with pituitary tumors. In the early 20th century, multiple investigators attempted to extract a growth-promoting factor from the anterior pituitary and then, over the decades, to purify it and distinguish it from other anterior pituitary hormones. With relatively pure growth hormone (GH), its biological activity in growth promotion and as a metabolic hormone were studied, and species specificity became apparent: primate GH was the only GH active in man. Human GH was prepared from cadaveric pituitaries and distributed by the NIH to treat children with GH deficiency, but there was never enough pituitary hGH for all of the children who required it. When Creutzfeldt-Jakob disease was found in some patients who received pituitary GH, the production and FDA approval of biosynthetic hGH dramatically accelerated. With a large supply, one could treat those who were GH deficient and test its efficacy in other causes of short stature; longer acting versions of hGH have now been developed, tested, and in a few instances received FDA approval. SUMMARY: It has been a long journey from the description of over- and underproduction of GH in animals to the production and clinical use of the biosynthetic hormones. KEY MESSAGES: The efforts of basic scientists led to the extraction and purification of GH. Clinical scientists have expanded the appropriate use of hGH for short children with conditions in addition to GH deficiency.

A case of dwarfism in 6th century Italy: Bioarchaeological assessment of a hereditary disorder.

OBJECTIVE: The skeletal remains of a short-statured individual (T17) are described and a differential diagnosis performed to determine the etiology of the condition. MATERIALS: An individual considered pathologically short in stature was discovered in the burial site of Piazza XX Settembre, Modena (northern Italy). METHODS: Morphological and morphometric analyses were performed, and T17 was compared to dwarfs from other localities and periods and to the adult female population from the same site. A paleopathological survey was undertaken to assess the degree of the skeletal elements of T17 were affected. RESULTS: T17 was a female, 20-30 years of age at death, with a stature of 128 cm and disproportionate dwarfism associated with congenital skeletal dysplasia. CONCLUSIONS: T17 likely affected by a form of hypochondroplasia. SIGNIFICANCE: Anatomical consequences of hypochondroplasia are presented, and the timeframe and associated burial goods suggest a 6th-century Lombard short stature belonging to one of the earliest Lombard settlements in Italy. SUGGESTIONS FOR FURTHER RESEARCH: Future genetic analysis would resolve if the mutation in the type 3 fibroblast growth factor receptor (FGFR3) is present in the remains of T17; however, it is not exclusivly linked to hypochondroplasia.

Trabecular bone microarchitecture analysis, a way for an early detection of genetic dwarfism? Case study of a dwarf mother's offspring.

A 66 year-old woman with a disproportionate dwarfism and who bore seven children was discovered at the Middenbeemster archaeological site (The Netherlands). Three are perinates and show no macroscopic or radiological evidence for a FGFR3 mutation causing hypo-or achondroplasia. This mutation induces dysfunction of the growth cartilage, leading to abnormalities in the development of trabecular bone. Because the mutation is autosomal dominant, these perinates have a 50% risk of having been affected. This study determines whether trabecular bone microarchitecture (TBMA) analysis is useful for detecting genetic dwarfism. Proximal metaphyses of humeri were µCT-scanned with a resolution of 7-12 µm. Three volumes of interest were segmented from each bone with TIVMI© software. The TBMA was quantified in BoneJ© using six parameters on which a multivariate analysis was then performed. Two of the Middenbeemster perinates show a quantitatively different TBMA organization. These results and the family's medical history suggest a diagnosis of genetic dwarfism for this two perinates. This study provides evidence to support the efficacy of µCT for diagnosing early-stage bone disease.

The smallest of the small.

Microcephalic Osteodysplastic Primordial Dwarfism (MOPD) II has recently been defined as a PCNT gene defect. Historically, it has been a disorder of interest because of the severe intrauterine growth restriction and postnatal short stature. The very shortest/smallest mature human being undoubtedly had this disorder. Maria Zarate lived between 1864 and 1890 and traveled in sideshows to England and all over North America. Her exceeding short stature was well documented in photographs and by a group of physicians in England. She was Mexican and also had an affected brother. A museum, Museo Casa Grande, about her still exists in Cempoala, Mexico.

Microcephalic osteodysplastic primordial dwarfism, with the fascinating history of "Mademoiselle Crachami".

This review critically examines the findings which characterize the dysmorphic, radiologic and behavioral phenotype of Microcephalic Osteodysplastic Primordial Dwarfism (MOPD) and has an historical perspective on it. MOPD is a group of primordial dwarfism syndromes with prenatal onset growth retardation, a typical craniofacial appearance and behavioral phenotype. In 1959, Mann and Russell have described the first case in a detailed report, and named "microcephalic midget of extreme type". In their report; based on historical records and a small painting, they pointed "Mademoiselle Crachami" as the oldest known case.

Skeletal dysplasia in ancient Egypt.

The ancient Egyptian civilization lasted for over 3000 years and ended in 30 BCE. Many aspects of ancient Egyptian culture, including the existence of skeletal dysplasias, and in particular achondroplasia, are well known through the monuments and records that survived until modern times. The hot and dry climate in Egypt allowed for the preservation of bodies and skeletal anomalies. The oldest dwarf skeleton, the Badarian skeleton (4500 BCE), possibly represents an epiphyseal disorder. Among the remains of dwarfs with achondroplasia from ancient Egypt (2686-2190 BCE), exists a skeleton of a pregnant female, believed to have died during delivery with a baby's remains in situ. British museums have partial skeletons of dwarfs with achondroplasia, humeri probably affected with mucopolysaccharidoses, and a skeleton of a child with osteogenesis imperfecta. Skeletal dysplasia is also found among royal remains. The mummy of the pharaoh Siptah (1342-1197 BCE) shows a deformity of the left leg and foot. A mummified fetus, believed to be the daughter of king Tutankhamun, has scoliosis, spina bifida, and Sprengel deformity. In 2006 I reviewed the previously existing knowledge of dwarfism in ancient Egypt. The purpose of this second historical review is to add to that knowledge with an expanded contribution. The artistic documentation of people with skeletal dysplasia from ancient Egypt is plentiful including hundreds of amulets, statues, and drawing on tomb and temple walls. Examination of artistic reliefs provides a glance of the role of people with skeletal dysplasia and the societal attitudes toward them. Both artistic evidence and moral teachings in ancient Egypt reveal wide integration of individuals with disabilities into the society.

From Horus the child to Hephaestus who limps: a romp through history.

The question of why Hephaestus, the Greek god of smiths, limped has been the subject of much debate, mainly on mythological grounds. This debate extended also into the field of medical diagnosis, with attempts at defining the nature of the deformity that made the crippled Hephaestus the buffoon of the other Olympic gods. One problem encountered in these debates was the changes to which the ugly young Hephaestus was subjected with the passing of time-from a limping deformed youth to the later dignified and normal man. While some authors, largely influenced by poetic Greek texts and vase paintings, attributed the limp to talipes (club-feet), others pointed to certain features suggestive of achondroplasia. Since the image of the early Hephaestus is based mainly on the much earlier concept of the Egyptian god Ptah, who as the triune god of the resurrection sometimes is depicted as an achondroplastic dwarf (Ptah-Pataikos), the suggestion of the possible achondroplastic dwarf-like nature of the early Hephaestus is not implausible. It is supported by similarities in the image of Hephaestus to some features in other Egyptian gods, such as the domestic god Bes, the guardian of the new-born, and the Horus the Child or Harpocrates (Greek), yet another protector of youth and "the symbol of everything that is young and vigorous" [Budge, 1969: The Gods of the Egyptians, or Studies in Egyptian Mythology. Volume I.]. The characteristic feature of this child-god is the "lock of Harpocrates" on the right side of his head. That this lock can sometimes also be seen not only on the head of Ptah-Pataikos and of Bes but also on the young Hephaestus is highly suggestive of the Egyptian influence on his image. Recently, however, another interesting explanation of Hephaestus's limp has been suggested that may explain why the Egyptian influenced image of the early achondroplastic Hephaestus changed to the later, more Grecian view of the smith-god who hobbled because of club-feet. Improvements in composition-analysis of samples from antique statues and various utensils have led to the suggestion that the introduction of new smelting techniques in antique times may have exposed ancient metal workers to the effects of various toxic metals causing, for instance, chronic lead poisoning or, more relevant here, chronic arsenic poisoning causing peripheral neuritis with weakness and lameness of one or both lower extremities. Later changes in smelting technique, and recognition or guess-work of a possible connection between these techniques and toxic effects, may explain the change from the buffoon-like achondroplastic walk to the club-footed limp and eventual normal behaviour of Hephaestus, the Smith. In other words: Did Hephaestus limp because of his arsen-neuritis?

Dwarfism and gigantism in historical picture postcards.

A collection of 893 historical picture postcards from 1900 to 1935, depicting dwarfs and giants, was analysed from medical and psychosocial viewpoints. In conditions such as 'bird headed dwarfism', achondroplasia, cretinism, so-called Aztecs or pinheads, Grebe chondrodysplasia, and acromegalic gigantism, the disorder could be diagnosed easily. In hypopituitary dwarfism, exact diagnosis was more difficult because of heterogeneity. The most common conditions depicted were pituitary dwarfism and achondroplasia. Most of those with gigantism had pituitary gigantism and acromegaly. Brothers and sisters or parents and their children provided evidence of mendelian inheritance of some of these disorders. The cards suggest that being put on show provided, at least in some cases, social benefits.

Alice Vance ("Das Bärenweib"): a historical case of Nievergelt syndrome.

Several malformed individuals were presented at the World Exhibition in Antwerp in 1894. Among them was Mrs. Alice Vance from Mount Pleasant, Texas, with congenital limb defects, and Mr. Eugen Berry, who had asymmetrical, monstrous enlargement and macrodactyly of the feet, i.e., Proteus syndrome. After the World Exhibition Mrs. Vance presented herself to the public in Castan's Panopticon imitating a bear. She became famous under the stage name "Das Bärenweib" ("the bear-like woman") and was examined by several German clinicians, and her malformations were considered to be of high scientific interest. Mrs. Vance had mesomelic dwarfism and her mother was known to have similar malformations. Her limb deficiencies were generally considered a unique congenital condition those days, and the diagnosis of "a maternally inherited malformation of the forearms and the shanks" [Daffner 1898: Munch Med Wochenschr 25:782] was made. Virchow [1897: Verh Berl Ges Ethnol Urgeschichte 29:624], feeling attacked by a daily newspaper stating that the physicians as well as the police of Berlin had missed the diagnosis of an "English disease," eventually exercised his authority and diagnosed Alice Vance as a "phocomelic." Clearly, she was not a phocomelic according to past and current definition of this term. Thus, from a historical point of view, the story illustrates how pressure from the daily press altered the definition of an up-to-then precisely defined medical term for decades. According to the clinical data and an X-ray report available from the literature, Alice Vance had a dominantly inherited type of mesomelic dwarfism. We propose the diagnosis of Nievergelt syndrome.

Historical case of dwarfism: attempted diagnosis.

A brief description is given of a male dwarf painted by the Italian artist Geromo Induno in 1852. This portrayal seems not to have been mentioned previously in the medical literature. Several experts were consulted in an attempt to diagnose the underlying skeletal dysplasia. Most opted for pseudoachondroplasia, with the most detailed argument coming from the subject of this Festschrift.

A case of chondrodystrophic dwarfism in the Italian late Upper Paleolithic.

During excavations by P. Graziosi at Romito Cave near Papasidero (Cosenza) in Calabria, Italy, two skeletons (Romito 1 and 2) were discovered in a common grave. Although the specimens were briefly described by Messeri (Atti X Riuniuone Scientifica Ist. Ital. Preist. Protost., pp. 301-307, 1966), it is generally unknown in the anthropological literature that one of these individuals is a chondrodystrophic dwarf. As such, the specimen provides the earliest known case of dwarfism in the human skeletal record, extending the time span of this genetically determined growth abnormality to approximately 10,000 years ago. The specimen (Romito 2) exhibits features typical of chondrodysplasia, including a high domed skull, compressed cranial base, and in the postcranial skeleton extremely shortened diaphyseal lengths. The unique combination of these features suggests this pathological condition is acromesomelic dysplasia. Besides providing evidence for a greater antiquity of dwarfism than previously known, the fact that this individual reached late adolescence attests to tolerance of Upper Paleolithic groups for severely abnormal individuals and their ability to support members who were of limited economic value to the social group.
