Findings from twin studies of musical interests and talent are reviewed as a backdrop to the lives and careers of twin jazz musicians, Peter and Will Anderson. The Anderson twins exemplify many aspects of twin research, namely their matched musical abilities, shared musical interests, and common career. This overview is followed by reviews of studies and case reports of bereavement in families who have lost a preterm multiple birth infant, the conception of conjoined twins following in vitro fertilization (IVF), depression in fathers of twins, and twin-to-twin transfusion incidence in monochorionic-diamniotic IVF twin pairs...

The separation of conjoined twins is a rare event in the medical field and presents many unique challenges to overcome. With the complexities of today's interconnected healthcare technology and electronic medical record, there are many intricate details that need significant attention to guarantee proper care and accurate record keeping for conjoined twins. Items that require attention are how to digitally represent the twins-as 1 patient or 2, how to incorporate the physiological monitors into the medical record, and how to ensure the proper amount of infrastructure, equipment, and space...

Conjoined twins are extremely rare and are a type of monozygotic twins that occur due to an incomplete embryonic division on postconception day 13 to 15. Eight different types of conjoined twins have been described in the literature. Management of the condition depends on the site and extent of the union. We present a case of cephalopagus twins diagnosed at 14 weeks of gestation.

INTRODUCTION: Conjoined twins are an infrequent occurrence in obstetric practice. Live-conjoined twins on a late preterm triplet pregnancy is an even rarer event. OBJECTIVE: The objective of this study is to emphasize the critical importance of perinatal palliative care and non-directive parental counseling, informed decision making and respect for autonomy following full disclosure of findings, fetal life-limiting diagnosis, treatment alternatives, maternal-fetal potential complications, and most likely perinatal outcomes...

A female pair of conjoined twins of the Lhasa Apso canine breed was subjected to tomographic and anatomical examinations. The twins had only one head and neck. The two ribcages were joined, extending to the umbilicus, with duplicated structures thereafter. They had three thoracic limbs and two pelvic girdles with four limbs, as well as a number of abnormalities in their internal organs. The data obtained were compared with the rare canine cases reported so far and with human cases.

In a physical neural system, learning rules must be local both in space and time. In order for learning to occur, non-local information must be communicated to the deep synapses through a communication channel, the deep learning channel. We identify several possible architectures for this learning channel (Bidirectional, Conjoined, Twin, Distinct) and six symmetry challenges: (1) symmetry of architectures; (2) symmetry of weights; (3) symmetry of neurons; (4) symmetry of derivatives; (5) symmetry of processing; and (6) symmetry of learning rules...

Conjoined twins are identical twins that have incompletely separated in utero. The prognosis for conjoined twins is poor and management in a skilled tertiary care centre is paramount for definitive care. We describe our experience with a telemedical consultation on conjoined twins in The Dominican Republic from our eHealth centre in Valhalla, NY. The patients were two month old, female, pygopagus conjoined twins. A multidisciplinary teleconference was initiated with the patients, their family, the referring paediatrician and our team...

Preoperative assessment of tissue anatomy and accurate surgical planning is crucial in conjoined twin separation surgery. We developed a new method that combines three-dimensional (3D) printing, assembling, and casting to produce anatomic models of high fidelity for surgical planning. The related anatomic features of the conjoined twins were captured by computed tomography (CT), classified as five organ groups, and reconstructed as five computer models. Among these organ groups, the skeleton was produced by fused deposition modeling (FDM) using acrylonitrile-butadiene-styrene...

BACKGROUND: Gynecologic surgeries are performed through abdominal, vaginal, laparoscopic, or robot-assisted laparoscopic routes. However, if the pelvis is not accessible by one of these routes, there are no published reports to guide pelvic surgeons. CASE: A 34-year-old conjoined twin status postseparation with uterine didelphys and absence of her left colon and sacrum underwent hemihysterectomy, at which time her müllerian anomaly was unknown. She re-presented with vaginal bleeding and pain eventually attributed to a retained uterine horn...

The late neurologist and author, Oliver Sacks, published an insightful 1986 review of Marjorie Wallace's book, The Silent Twins, in the New York Times. Taking exception to his assertion about Sir Francis Galton, I wrote a letter to the Times' editor. The letter was unpublished, but it brought a wonderful response from Sacks himself that is reproduced and examined. Next, brief reviews of twin research concerning the vanishing twin syndrome (VTS), discordant sex in a monozygotic (MZ) twin pair, and multiple pregnancy outcomes from assisted reproductive technology (ART) are presented...

Craniopagus is a very rare congenital anomaly that tends to affect females more often than males. It is classified as partial or total. Most affected twins are either stillborn or die during the perinatal period. Those who survive birth should undergo detailed radiological evaluations soon after their condition becomes stable so that the precise anatomy of the conjoined part can be defined and surgery can be planned in detail by a multidisciplinary team. Recommendations for decreasing the risk of unsuccessful surgery include performing surgery on an elective basis after extensive preoperative radiological evaluations as well as when the twins are at an acceptable age and weight for a complex surgical separation, generally as staged procedures...

BACKGROUND: The three-dimensional (3D) technique provides with accurate anatomical information. We present the separation surgeries for three different kinds of conjoined twins with the aid of three-dimensional techniques. METHOD: For the pygopagus twins, a pelvic and lower vertebral model was made. For the omphalopagus and ischiopagus, their enhanced computed tomography (CT) scan images were transferred to the Computer-Assisted Surgery Planning System (CASP) (Hisense, Qingdao, China) to generate the 3D models...

Conjoined twinning is an embryological anomaly rarely reported in wild mammals and with only two previous records in Chiroptera. Here, we report a case of dicephalic parapagus conjoined twins in the Neotropical phyllostomid genus Artibeus. These twins are males and present separated heads and necks, but a conjoined trunk with an expanded upper thoracic region. They developed two complete forelimbs and two complete hindlimbs, all laterally to the trunk. There is a volume in the upper midback and between the heads that resembles a third rudimentary medial forelimb, but X-ray images only suggest the presence of medial skeletal elements of the pectoral girdle (clavicle and scapulae) in this region...

The article highlights the power of mobile technology in expanding access to quality healthcare by telling the story of the first successful operation by Afghan doctors to separate conjoined twins at The French Medical Institute for Mothers and Children (FMIC) in Kabul, Afghanistan's capital. Roshan, Afghanistan's leading telecommunications provider, set up the telemedicine link in 2007, connecting three hospitals in Kandahar, Bamiyan and Badakhshan Provinces to FMIC in Kabul, and all three to one of the best and most modern hospitals in the region: The Aga Khan University Hospital in Karachi, Pakistan...

Conjoined twins are derived from division of a single fertilized ovum after the twelfth day of fertilization. Triplet conjoined twin is considered as a unique phenomenon that is accompanied with a wide variety of congenital abnormalities and also hazardous consequences for both fetuses and parents. We present an extremely rare case of conjoined twins in a triplet pregnancy with symmetric thoracoomphalopagus that was diagnosed in prenatal period by using ultrasound scanning and MRI. In triplet pregnancies, we should be aware about the possibility of conjoined twins...
