Secondary nail deformities are often seen at some time after fingertip and nail bed injuries. A proper evaluation of the fingernail enables appropriate diagnosis and treatment, especially in patients who need surgical management. To date, ultrasound and magnetic resonance imaging are the only diagnostic tools that most surgeons use in cases of nail deformities. Herein, we report the case of a patient with a nail deformity who underwent successful correction based on the preoperative use of real-time optical coherence tomography.

PURPOSE: This study aimed to evaluate the clinical usefulness of non-invasive prenatal testing (NIPT) as an alternative testing of invasive diagnostic testing in pregnancies with ultrasound abnormalities. MATERIALS AND METHODS: This was a retrospective study of pregnant women with abnormal ultrasound findings before 24 weeks of gestation between April 2016 and March 2017. Abnormal ultrasound findings included isolated increased nuchal translucency, structural anomalies, and soft markers. The NIPT or diagnostic test was conducted and NIPT detected trisomy 21 (T21), T18, T13 and sex chromosomal abnormalities. We analyzed the false positive and residual risks of NIPT based on the ultrasound findings. RESULTS: During the study period, 824 pregnant women had abnormal ultrasound findings. Among the study population, 139 patients (16.9%) underwent NIPT. When NIPT was solely performed in the patients with abnormal ultrasound findings, overall false positive risk was 2.2% and this study found residual risks of NIPT. However, the discordant results of NIPT differed according to the type of abnormal ultrasound findings. Discordant results were significant in the group with structural anomalies with 4.4% false positive rate. However, no discordant results were found in the group with single soft markers. CONCLUSION: This study found different efficacy of NIPT according to the ultrasound findings. The results emphasize the importance of individualized counseling for prenatal screening or diagnostic test based on the type of abnormal ultrasound.

During the past decades, there has been a great evolution in the field of fetal therapy for congenital defects. Prenatal screening or diagnostic methods including non-invasive and invasive methods and fetal ultrasound have led to earlier and more accurate diagnosis of congenital anomalies. Recent advances in several therapeutic techniques including ultrasound-guided needle therapy, laser therapy or fetal endoscopy, have allowed some fetuses at risk with anatomical defects, to be corrected in utero but still, its clinical indications remain limited. Over the last 30 years, many researchers found usefulness of pluripotent stem cells from amniotic fluid and placenta because they are sources of diverse progenitor cell populations called mesenchymal stem cells. In some human conditions like severe combined immunodeficiency syndrome and chronic granulomatous disease, fetal therapy using stem cell replacement showed some promising results in researches but more studies are required to apply in clinical settings. The aim of this article is to summarize a current status and future perspective of stem cell therapy for treatment of congenital fetal anomalies.

PURPOSE: The purpose of this study was to evaluate the feasibility and usefulness of sagittal color Doppler ultrasonography (CDUS) for the diagnosis of fetal cleft lip (CL) and cleft palate (CP). METHODS: We performed targeted ultrasonography on 25 fetuses with CL and CP, taking coronal and axial images of the upper lip and maxillary alveolar arch in each case. The existence of defects in and malalignment of the alveolus on the axial image, hard palate defects on the midsagittal image, and flow-through defects on CDUS taken during fetal breathing or swallowing were assessed. We compared the ultrasonography findings with postnatal findings in all fetuses. RESULTS: Alveolar defects were detected in 16 out of 17 cases with CP and four out of eight cases with CL. Alveolar malalignment and hard palate defects were detected in 11 out of 17 cases and 14 out of 17 cases with CP, respectively, but not detected in any cases with CL. Communicating flow through the palate defect was detected in 11 out of 17 cases of CL with CP. The accuracy of detection in axial scans of an alveolar defect and malalignment was 80% and 76%, respectively. Accuracy of detection of in mid-sagittal images of hard palate defect and flow was 80% and 86%, respectively. The overall diagnostic accuracy of combined axial and sagittal images with sagittal CDUS was 92%. CONCLUSION: Sagittal CDUS of the fetal hard palate is a feasible method to directly reveal hard palate bony defects and flow through defects, which may have additional value in the differential diagnosis of fetal CL and CP.

BACKGROUND: The prenatal ultrasound detection of cleft lip with or without cleft palate (CL/P) and its continuous management in the prenatal, perinatal, and postnatal periods using a multidisciplinary team approach can be beneficial for parents and their infants. In this report, we share our experiences with the prenatal detection of CL/P and the multidisciplinary management of this malformation in our institution's Congenital Disease Center. METHODS: The multidisciplinary team of the Congenital Disease Center for mothers of children with CL/P is composed of obstetricians, plastic and reconstructive surgeons, pediatricians, and psychiatrists. A total of 11 fetuses were diagnosed with CL/P from March 2009 to December 2013, and their mothers were referred to the Congenital Disease Center of our hospital. When CL/P is suspected in the prenatal ultrasound screening examination, the pregnant woman is referred to our center for further evaluation. RESULTS: The abortion rate was 28% (3/11). The concordance rate of the sonographic and final diagnoses was 100%. Ten women (91%) reported that they were satisfied with the multidisciplinary management in our center. CONCLUSIONS: Although a child with a birth defect is unlikely to be received well, the women whose fetuses were diagnosed with CL/P on prenatal ultrasound screening and who underwent multidisciplinary team management were more likely to decide to continue their pregnancy.

Ultrasonography in obstetrics is increasingly used for the screening of chromosomal abnormalities as well as for prenatal diagnosis of congenital abnormalities with safety and technological advancements. In the first trimester, it is important to confirm normal intrauterine pregnancy with viability, detect the abnormalities of uterus and adnexa, determine the number of fetuses and assess chorionicity and amnionicity in case of multiple pregnancy. After establishment of gestational age accurately by crown-rump length, thickened fetal nuchal translucency, absence of nasal bone, tricuspid regurgitation, reverse a wave of ductus venosus and cystic hygroma can be markers for screening of chromosomal abnormalities. In addition, the scan also offers an opportunity to detect gross structural abnormalities, which could help improve the prognosis by early prenatal intervention. In the second trimester, aneuploidy (trisomy 21, 18, 13, Turner syndrome) and genetic syndromes could be detected by major structural defects and soft markers. It is important to consider that many malformations may not be detected prenatally even by qualified practitioners and appropriate equipment, and to counsel patients about the potential for false-positive or false-negative results.

BACKGROUND: Glomus tumors were first described by Wood in 1812 as painful subcutaneous tubercles. It is an uncommon benign neoplasm involving the glomus body, an apparatus that involves in thermoregulation of cutaneous microvasculature. Glomus tumor constitutes 1%-5% of all hand tumors. It usually occurs at the subungual region and more commonly in aged women. Its classical clinical triad consists of pain, tenderness and temperature intolerance, especially cold sensitivity. This study reviews 15 cases of glomus tumor which were analyzed according to its anatomic location, surgical approach and histologic findings. METHODS: Fifteen patients with subungual glomus tumors of the hand operated on between January 2006 and March 2013, were retrospectively reviewed. Patients were evaluated preoperatively with standard physical examination including ice cube test and Love's test. Diagnostic imaging consisted of ultrasonography, computed tomography, and magnetic resonance imaging. All procedures were performed with tourniquet control under local anesthesia. Eleven patients underwent excision using the transungual approach, 3 patients using the volar approach and 1 patient using the lateral subperiosteal approach. RESULTS: Total of 15 cases were reviewed. 11 tumors were located in the nail bed, 3 in the volar pulp and 1 in the radial aspect of the finger tip. After complete excision, patients remained asymptomatic in the immediate postoperative period. In the long term follow up, patients exhibited excellent cosmetic results with no recurrence. CONCLUSIONS: Accurate diagnosis should be made by physical, radiologic and pathologic examinations. Preoperative localization and complete extirpation is essential in preventing recurrence and subsequent nail deformity.

PURPOSE: To report the incidence of dacryocystoceles detected by prenatal ultrasonography (US) and their postnatal outcomes and to determine the factors associated with the postnatal persistence of dacryocystoceles at birth. METHODS: We retrospectively reviewed the prenatal US database at our institution for the period between January 2012 and December 2013. The medical records of women who had fetuses diagnosed with dacryocystocel larger than 5 mm were reviewed for maternal age, gestational age (GA) at detection, size and side of the dacryocystoceles, delivery, and postnatal information, such as GA at delivery, delivery mode, and gender of the neonate. RESULTS: A total of 49 singletons were diagnosed with a dacryocystocele on prenatal US, yielding an overall incidence of 0.43%. The incidence of dacryocystoceles was the highest at the GA of 27 weeks and decreased toward term. Of the 49 fetuses including three of undeter mined gender, 25 (54%) were female. The mean GA at first detection was 31.2 weeks. The dacryocystocele was unilateral in 29 cases, with a mean maximum diameter of 7 mm. Spontaneous resolution at birth was documented in 35 out of 46 neonates (76%), including six with prenatal resolution. Multivariate analysis demonstrated that GA at delivery was a significant predictor of the postnatal persistence of dacryocystoceles (P=0.045). CONCLUSION: The overall incidence of prenatal dacryocystoceles was 0.43%; the incidence was higher in the early third trimester and decreased thereafter. Prenatal dacryocystoceles resolved in 76% of the patients at birth, and the GA at delivery was a significant predictor of postnatal persistence.

Subungual glomus tumors are benign neoplasms that arise from the neuromyoarterial apparatus. They present with various clinical symptoms such as localized pain, tenderness, and sensitivity to temperature change and can be palpated as a nodule or mass on physical examination. Pressure erosion can be seen at adjacent bones on radiography. However, in most cases, the tumors are too small to be inspected and located under the nail plate, which makes correct diagnosis and complete excision very difficult. Incomplete removal can cause recurrence or deformity to the residual nail, whereas extensive removal can cause trauma or deformity to the nail plate. Thus, correct differential diagnosis and preoperative evaluation of the location and extent of the tumor are very important. Here, we report 2 cases that were diagnosed and preoperatively evaluated using ultrasound.

The incidence of fetal tumors has been increased due to generalization of prenatal evaluation and improvement of imaging techniques. The early detection of a fetal tumor and understanding of its imaging features are very important for fetal, maternal, and neonatal care. Ultrasonography is usually used for the detection and differential diagnosis of fetal tumors, and magnetic resonance imaging is increasingly being used as a complementary study. Many fetal tumors have different clinical and imaging features compared with pediatric tumors. Although several fetal tumors may mimic other common anomalies, some specific imaging features may carry early accurate diagnosis of fetal tumors, which may alter the prenatal management of a pregnancy and the mode of delivery, and facilitate immediate postnatal treatment.
