Monosymmetros Cephalothoracopagus Tetrabrachius and Tetrapus Piglets with Syndromic Evolution

Conjoined twins are rare congenital malformations that have been reported in mammals. Two different cases are presented in this study. Case No. 1 features monocephalic, thoracopagus-conjoined twin piglets with anencephaly and palatoschisis of the Pietrain breed, and case No. 2 features monocephalic, thoracopagus conjoined twin piglets with palatoschisis and bifid root tongue of a mixed breed. These cases were examined using post-mortem and computed tomography (CT) examinations. In both cases, the conjoined symmetrical twins had a single head, one neck, and fused thoracic cavities, while the abdominal cavities were separated. Similarly, in both cases, they had four forelimbs and four hindlimbs and duplicated foramen magnum. During CT examination, in case No. 1, severe abnormalities were observed in the skull and vertebral column. In the left twin, occult dysraphism was seen from the C2 vertebra until the end of the vertebral column, and in the right twin, from the C3 vertebra until the end of the state vertebral level. In case No. 2, the oral cavity contained a tongue with a bifid root connected with one hyoid bone, and the soft palate presented a small cleft. During CT examination, the parietal bone and the occipital bones were partially duplicated. This case also presented occult dysraphism, but only in the cervical vertebrae, C1-C6 for the left twin and C1-C5 for the right twin. In both cases, abnormalities of the internal organs were revealed during necropsy. Conjoined twins with multiple congenital anomalies presented here enhance our understanding of the various clinical forms of conjoined cases in veterinary medicine.

Exencephaly-Anencephaly Sequence Associated with Maxillary Brachygnathia, Spinal Defects, and Palatoschisis in a Male Domestic Cat

Anencephaly, a severe neural tube defect characterized by the absence of major parts of the brain and skull, is a rare congenital disorder that has been observed in various species, including cats. Considering the uncommon appearance of anencephaly, this paper aims to present anencephaly in a stillborn male kitten from an accidental inbreeding using various paraclinical methods. Histological examination of tissue samples from the cranial region, where parts of the skull were absent, revealed the presence of atypical nerve tissue with neurons and glial cells organized in clusters, surrounded by an extracellular matrix and with an abundance of blood vessels, which are large, dilated, and filled with blood, not characteristic of nerve tissue structure. In CT scans, the caudal part of the frontal bone, the fronto-temporal limits, and the parietal bone were observed to be missing. CT also revealed that the dorsal tubercle of the atlas, the dorsal neural arch, and the spinal process of the C2-C7 bones were missing. In conclusion, the kitten was affected by multiple congenital malformations, a combination of exencephaly-anencephaly, maxillary brachygnathism, closed cranial spina bifida at the level of cervical vertebrae, kyphoscoliosis, palatoschisis, and partial intestinal atresia. The importance of employing imaging techniques cannot be overstated when it comes to the accurate diagnosis of neural tube defects.

The Impact of Communication Surrounding Intrauterine Congenital Anomaly Diagnoses: An Integrative Review

Congenital anomalies are the leading cause of infant death in the United States, accounting for 20% of the annual infant mortality. Advancements in ultrasound diagnostic technology allow practitioners to diagnose fetal anomalies as early as 11 weeks' gestational age, 75% of which are detected in low-risk pregnancies. Communicating a fetal anomaly diagnosis to parents and initiating perinatal end-of-life discussions are difficult for healthcare providers and parents alike. Furthermore, poorly communicated diagnoses have had long-term negative impacts on perinatal grief intensity, which can manifest into lifelong symptoms of adverse psychosocial outcomes such as anxiety, depression, substance abuse, and suicidal ideation. The purpose of this integrative review is to examine the impact of communication in discussing an intrauterine diagnosis of a fetal congenital anomaly on perinatal grief. An integrative review was conducted following the distinct 5-stage process of problem identification, searching the literature, evaluating data, analyzing, and presenting findings. A systematic literature review using the PICO model (Population, Intervention, Comparison, Outcome) and structured after the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA). This framework was completed between November 2017 and May 2018 using PubMed, CINAHL, and PsycINFO databases. Of the 931 article results, 15 satisfied search criteria. Emerging themes included parental need for appropriate time to assimilate and understand the diagnosis, freedom to explore options and alternatives, and the need for clinicians with expert communication skills. The initial conversation communicating the diagnosis of a congenital anomaly impacts expectant parents for the remainder of their lives. Healthcare professionals are in a unique position to either positively or negatively impact the intensity of perinatal grieving reactions. The application of empathetic, sensitive communication may offer solace and promote healing surrounding perinatal end-of-life discussions.
