Abstract
INTRODUCTION Underdevelopment of the nose is a wide spectrum entity ranges from partial absence of the nose to congenital arrhinia (CA). CA is the congenital absence of the external nose, nasal cavities, and/or nasal nostrils±olfactory apparatus, and is an extremely rare entity as less than 50 cases reported in the literature. CA can be isolated and idiopathic in origin or be a part of genetic-linked certain syndromes. Of note, the isolated CA can be inherited as an autosomal dominant condition with incomplete penetrance. PRESENTATION OF CASE We report a 13-month-old Palestinian female patient with isolated CA complicated with recurrent lower and upper respiratory tract infections (URTI). The family history is significant for the mother with incomplete and uncomplicated underdevelopment of the external nose and nasal nostrils. The patient uses a tracheostomy to breathe and is waiting for the optimal age for surgical correction. In addition, we reviewed the available literature using PubMed and summarized all CA cases reported from 2016 to 2019 since two studies had presented the literature before 2016, and presented them in a very comprehensive table. DISCUSSION CA is largely idiopathic and not well understood. Although CA can be inherited and runs in families with incomplete penetrance, no causative genetic abnormalities had been found in most of the reported cases. CA frequently presents with upper airway obstruction and respiratory distress, recurrent lower and URTI, and feeding difficulties. CA is managed initially with tracheostomy and should be followed by a surgical correction at the appropriate age. CONCLUSION CA may be sporadic, familial, or a part of a syndrome. CA carries a significant rate of morbidity and mortality and a tracheostomy should be inserted initially to alleviate the early CA complications and followed by surgical reconstruction when the patient reaches the age of preschool/school age. More studies are required to determine CA inheritance.

Abstract
The human face is a complex anatomic structure with an equally complex embryologic development. Derangement of the developmental process can result in various structural anomalies, which range from a mainly cosmetic deformity, such as cleft lip, to potentially life-threatening conditions such as arhinia. These anomalies (a) can occur as isolated anomalies; (b) can be associated with intracranial, spinal, or dental anomalies; or (c) can be a part of various syndromes, thus serving as diagnostic clues in such cases. Proper evaluation of fetal facial deformities can help in prognostication, family counseling, and prenatal or early postnatal intervention. Ultrasonography (US) is the first line of investigation in these cases. However, when US does not allow complete evaluation of these anomalies owing to its inherent limitations, magnetic resonance (MR) imaging allows comprehensive evaluation of the anomaly itself and also evaluation of various associations and the treatment approach. The embryology of the fetal facial structures is considered with regard to the MR imaging technique and the MR imaging anatomy. The MR imaging features of various structural anomalies are described and classified into six groups, namely, orofacial clefts, orbital anomalies, nasal anomalies, facial masses, external ear anomalies, and abnormal face shape or profile. Also, the key associations and relevant treatment implications are reviewed. The article provides a "one-stop shop" review of these unique disorders-from basic understanding of the embryology to applying the knowledge in clinical practice, helping the interprofessional team and the patients alike. ©RSNA, 2018.

Abstract
Complete congenital arhinia is a rare embryonic disorder of unknown etiology. This is a clinical report of the prosthetic nasal rehabilitations done in the early childhood and adolescent stages of a patient with complete congenital arhinia. Additive manufacturing techniques for creating presurgical planning models to assist in the creation of new nasal passages are also described. These rare disorders can be successfully rehabilitated if patients are sufficiently motivated and there is meticulous planning and collaboration from a multidisciplinary team.

Abstract
The use of selective serotonin reuptake inhibitors (SSRIs) for the treatment of depression during pregnancy is suggested to increase the incidence of craniofacial abnormalities including craniosynostosis. Little is known about this mechanism, however based on previous data we propose a mechanism that affects cell cycle. Excessive proliferation, and reduction in apoptosis may lead to hyperplasia within the suture that may allow for differentiation, bony infiltration, and fusion. Here we utilized in vivo and in vitro analysis to investigate this proposed phenomenon. For in vivo analysis we used C57BL–6 wild-type breeders treated with a clinical dose of citalopram during the third trimester of pregnancy to produce litters exposed to the SSRI citalopram in utero. At post-natal day 15 sutures were harvested from resulting pups and subjected to histomorphometric analysis for proliferation (PCNA) and apoptosis (TUNEL). For in vitro studies, we used mouse calvarial pre-osteoblast cells (MC3T3-E1) to assess proliferation (MTS), apoptosis (Caspase 3/7-activity), and gene expression after exposure to titrated doses of citalopram. In vivo analysis for PCNA suggested segregation of effect by location, with the sagittal suture, showing a statistically significant increase in proliferative response. The coronal suture was not similarly affected, however there was a decrease in apoptotic activity at the dural edge as compared to the periosteal edge. No differences in apoptosis by suture or area due to SSRI exposure were observed. In vitro results suggest citalopram exposure increased proliferation and proliferative gene expression, and decreased apoptosis of the MC3T3-E1 cells. Decreased apoptosis was not confirmed in vivo however, an increase in proliferation without a concomitant increase in apoptosis is still defined as hyperplasia. Thus prenatal SSRI exposure may exert a negative effect on post-natal growth through a hyperplasia effect at the cranial growth sites perhaps leading to clinically significant craniofacial abnormalities.

Abstract
Congenital arhinia is the absence of an external nose, nasal cavities and olfactory apparatus, and extremely rare. It occurs during the early gestational stage and may be a result of maldevelopment of the paired nasal placodes embryologically. Total arhinia is often associated with other craniofacial abnormalities. Early detection may be helpful for the parents and physician. However, fewer than 40 patients with arhinia have been reported so far, and most of them were diagnosed after birth. To our knowledge, this is the first case diagnosed by fetal MRI during the second trimester of pregnancy, and confirmed by pathological examination.

Abstract
OBJECTIVE Escitalopram (ESC) is considered one of the most effective selective serotonin reuptake inhibitors for the treatment of major depression. However, little is known on its potential risk of inducing major malformations (MMs) and perinatal complications (PCs). Hence, aim of the present study is to provide a comprehensive review of the available literature on the safety profile of ESC during pregnancy and breastfeeding. METHODS MEDLINE and PubMed databases were searched for English language articles by using the following keywords: escitalopram, selective serotonin reuptake inhibitors, major malformations, perinatal complications, pregnancy, and breastfeeding. RESULTS Although some cases of MMs have been reported after maternal exposure to ESC during early pregnancy, the rate of these adverse events is substantially in the range of those reported in unexposed women. On the contrary, exposure to ESC seems to be significantly associated with some PCs. No adverse effects have been reported in the few studies evaluating its safety during breastfeeding. CONCLUSIONS The available data seem to support the notion that ESC might be considered safe during pregnancy, in particular as far as MMs is concerned. However, similar to other selective serotonin reuptake inhibitors, it could be associated with an increased risk of PCs. Given the paucity of the studies published so far, no definitive conclusions can be drawn on its safety profile during breastfeeding.
