The Boy with Two Heads Free
FREE THE BOY WITH TWO HEADS PDF Andy Mulligan | 400 pages | 01 Oct 2015 | Random House Children's Publishers UK | 9780552573474 | English | London, United Kingdom The Boy With Two Heads by Andy Mulligan He was writing of the Boy of Bengal after observing drawings The Boy with Two Heads collecting and reviewing the accounts of several of his peers. While the boy was remarkable for both his medical condition and perseverance, Home was actually incorrect in his initial assumptions. His remarkable life was very nearly extinguished immediately after his delivery as a terrified midwife tried to destroy the infant by throwing him into a fire. Miraculously, while he was rather badly burned about the eye, ear and upper head, he managed to survive. His parents began to exhibit him in Calcutta, where he attracted a great deal of The Boy with Two Heads and earned the family a fair amount of money. While the large crowds gathered to see the Two-Headed Boy The Boy with Two Heads parents took to covering the lad with a sheet and often kept him hidden — sometimes for hours at a time The Boy with Two Heads often in darkness. As his fame spread across India, so did the caliber of his observers. Several noblemen, civil servants and city officials arranged to showcase the boy in their own homes for both private gatherings and grand galas — treating their guests to up close examinations. When compared to the average child, both heads were of an appropriate size and development. The The Boy with Two Heads head sat atop the main head inverted and simply ended in a neck-like stump. -

Los gemelos monocigóticos, compartirán o no las membranas fetales dependiendo del momento en el que tiene lugar la división del embrión, siendo bicoriales biamnióticos, monocoriales biamnióticos o monocoriales monoamnióticos. Cuando la división del embrión sucede a partir del día trece, se forman los gemelos siameses, unidos por alguna parte de su cuerpo, y en algunos casos existen gemelos parasitarios, desarrollándose uno de los fetos sólo parcialmente y quedando unido al cuerpo de su co-gemelo. El embarazo múltiple conlleva un mayor riesgo de complicaciones fetales, maternas y perinatales, que las gestaciones unifetales. Siendo más frecuente el aborto, el retraso del crecimiento intrauterino y otras malformaciones congénitas. En los gemelos monocoriónicos diamnióticos cabe destacar el síndrome de transfusión entre gemelos TTTS ( Twin-To-Twin Transfusion syndrome), siendo su grado máximo la denominada Secuencia TRAP ( Twin-reversed arterial perfusion sequence). -

A Case of Sacral Parasite
Cong. Anom., 26: 321-330,1986 Original A Case of Sacral Parasite Shigeki TOKUNAGA, Takayoshi IKEDA, Takeshi MATSUO, Hiroshi MAEDA, Nobuko KUROSAKI* and Hozumi SHIMODA* First Department of Pathology, Nagasaki University School of Medicine, 12-4 Sakamoto-machi, Nagasaki 852, Japan and *First Department of Surgery, Naga- saki University School of Medicine, 7-1 Sakamoto-machi, Nagasaki 852, Japan ABSTRACT A case of sacral parasite is presented. A parasitic body with an im- complete lower limb was attached to the sacrococcygeal region of a female new- born at birth. The twins were easily separated by operation two days after birth. The parasite contained well developed small and/or large intestines, a multilocular cyst and a unilocular cyst. Histologically, the wall of the multilocular cyst con- sisted of tissues of three germ layers, such as central and peripheral nervous tissues, mature and immature intestine, pancreatic tissue, bronchial cysts, connective tissue, etc. The thick wall of the unilocular cyst consisted of central nervous tissue and connective tissue. The degree of differentiation of these tissues varied consider- ably. The parasite revealed no organ communication with the autosite. Since the operation, her growth and development have been favorable and no other abnor- malities have been found. Key words: conjoined twins, sacral parasite, diagnosis, pathogenesis Parasitic conjoined twins consist of incomplete twin (parasite) attached to the fully developed body of the co-twin (autosite). This is an extremely rare anomaly, especially in the sacrococcygeal region. The present paper describes the anatomy and histopathology with some immunohistochemical findings in the sacral parasite. The pathogenesis and diagnostic criteria of this anomaly are also discussed. -

Parasitic Twins [1]
Published on The Embryo Project Encyclopedia (https://embryo.asu.edu) Parasitic Twins [1] By: DeRuiter, Corinne Keywords: Fetus [2] Congenital disorders [3] Human development [4] Parasitic twins, a specific type of conjoined twins [6], occur when one twin ceases development during gestation [7] and becomes vestigial to the fully formed dominant twin, called the autositic twin. The underdeveloped twin is called parasitic because it is only partially formed, is not functional, or is wholly dependent on the autositic twin. In most cases, the phenotype of parasitic twins is one normal functioning individual with extra appendages or organs, leading to questions about whether or not the additional limbs and organs are in fact another person or just a mutation of the individual’s body. Researchers think that parasitic twins result from mechanisms similar to those that produce Vanishing Twin Syndrome [8]. On a developmental continuum with vanishing twin syndrome on one end and developmentally normal twins on the other, researchers propose that the patterns of conjoined twins [6] fall somewhere in the middle. Of the many types of parasitic twins, the most common is vestigial twins, when one individual has extra limbs or organs. The extra vestigial limbs are generally harmless to the autosite. Similarly, dipygus parasitic twins have duplications of legs, but may also have extra hands, feet, or sexual organs. An epigastric parasite describes an incomplete twin with usually just a torso or legs attached to the functioning twin’s abdomen. In some cases, there is also an undeveloped head imbedded in the autosite’s abdomen. Craniopagus parasiticus describes an autositic twin with an additional, parasitic head attached at the head. -

Many descriptions emphasised the ambiguous status of monstrous births with respect to categories such as male/female, single/twin, and animal/human. They were ‘unnatural’ occurrences in the sense that they were outside the normal course of nature, and as such they were considered to be evidence of divine intervention in natural processes. -

CATONEb a Practitioner, Mantova, Italy b School of Biosciences and Veterinary Medicine, University of Camerino SUMMARY Introduction - Fetiform teratoma is a rare form of teratoma in animals and people that resembles a malformed fetus. This paper describes the first case of highly differentiated extragonadal fetiform teratoma with cranial connection in an Italian- Friesian calf. Case presentation - A 35-day-old male Italian-Friesian calf weighing 55 kg was referred because of a mass localized in the fron- to-nasal region. The mass contained two lateral structures of similar size and conformation that were recognized as underde- veloped hind limbs, while at its center there was a small tail. The mass was surgically excised and sent to the pathologist for examination. Gross examination identified two femur-like rudimentary limbs and a sketch of bone located in between, morphologically referable to a rudimentary coxae-like bone. Some mucinous cysts, a virtual body cavity showing adipose and muscular tissues, some cartilaginous nuclei and a coelomatic body cavity were also noted. Histological examination showed differentiation into skin with dermal appendages, hair, adipose tissue, cartilage, bone, lymphoid tissue, neurovascular bundles, and a rudimentary tail. No neural tissue including spinal cord, brain matter, or gonadal differentiation was seen. On the basis of these findings, the mass was diagnosed as a highly differentiated extragonadal fetiform teratoma. -

ABSTRACT To report a case of twin reversal arterial perfusion sequence and its management by means of laser coagulation of the vascular malformation in the placenta. Twin reversed arterial perfusion sequence is a rare form of twin to twin transfusion syndrome occurring primarily in Monochorionic monoamniotic twins. The prevalence is about 1 in 35,000 pregnancies. The significance of this condition is that there is a normal foetus and an acardiac foetus. The blood is shunted from the normal twin to the acardiac twin through vascular malformations in the placenta. The normal twin faces a high risk of both morbidity and mortality due to cardiac failure. A case of twin reversal arterial perfusion sequence diagnosed at 22 weeks following a target scan underwent laser photocoagulation and gave birth vaginally at 30 weeks without any complications.
