Prenatal diagnosis of cleidocranial dysplasia: Case report on two cases with a negative family history.

Introduction: Cleidocranial dysplasia (CCD) is a rare autosomal dominant skeletal dysplasia that presents with abnormalities in the craniofacial region, teeth, and clavicles and is linked to mutation. Prenatal diagnoses of CCD have rarely been reported, and most of these cases have a positive family history. Here we report two prenatally diagnosed CCD cases without a positive family history.

Second trimester screening for the basilar artery: a new approach using slowflowHD.

Objectives: Sonographic evaluation of the basilar artery is challenging, and a limited number of reports are available about the prenatal period, as manual positioning of probes is technically difficult. The objective of this study was to describe a sonographic transabdominal approach based on slowflow HD for screening of the basilar artery during the second trimester scan.

Methods: A total of 49 women who were enrolled in a second trimester screening were included when the fetus was in the occipitoanterior position.

Ultrasound scoring system for prenatal diagnosis of placenta accreta spectrum.

Background: To develop an ultrasound scoring system for placenta accreta spectrum (PAS), evaluate its diagnostic value, and provide a practical approach to prenatal diagnosis of PAS.

Methods: A total of 532 pregnant women (n = 184 no PAS, n = 120 placenta accreta, n = 189 placenta increta, n = 39 placenta percreta) at high-risk for placenta accreta who delivered in the Third Affiliated Hospital of Zhengzhou University between January 2021 and December 2022 underwent prenatal ultrasound to evaluate placental invasion. An ultrasound scoring system that included placental and cervical morphology and history of cesarean section was created.

Dynamic Evaluation of the Rectus Abdominis Muscle before and after Delivery by Ultrasonography.

Objective: To evaluate the changes of rectus abdominis thickness and inter-rectus distance before and after delivery with high-frequency ultrasound.

Methods: A total of 148 pregnant women at 12 weeks of gestation who underwent prenatal examination in our hospital from January 2019 to March 2020 were selected, and 140 of them cooperated with rectus abdominis examination. According to the results of rectus abdominis examination 42 days after delivery, 97 patients were divided into the DRA group with rectus abdominis isolated and 43 patients were divided into the normal group with rectus abdominis not isolated.

Ultrasonographic study of fetal mandibular markers during the first trimester in a Chinese population.

Aim: To establish reference ranges for fetal mandibular markers in low-risk singleton pregnancies between 11 and 13 + 6 weeks of gestation in a Chinese population.

Methods: The inferior facial angle (IFA), transverse, and anteroposterior diameters of the mandible, and mandibular length were measured at 11-13 + 6 weeks of gestation. The utility of these sonographic markers for detecting micrognathia was explored in seven fetuses.

Uterine dehiscence in pregnant with previous caesarean delivery.

Background: The main risk factor for uterine scar dehiscence is a previous caesarean section. Better characterisation of the ultrasonographic features of uterine scar dehiscence may improve preoperative diagnostic accuracy in pregnant women with a caesarean scar. This study aimed to evaluate the ultrasonographic features of uterine scar dehiscence in pregnant women and maternal and neonatal outcomes.

[Morbidity of congenital heart disease in children with anorectal malformations and related treatment].

Objective: To investigate the morbidity of congenital heart defects(CHDs) in children with anorectal malformation, and to summarize appropriate treatment.

Methods: The clinical data and echocardiographic findings of 155 children with congenital anorectal malformations from the Third Affiliated Hospital of Zhengzhou University during January 2016 and October 2019 were reviewed. According to the surgical findings of anorectal malformations, the patients were categorized as the high/intermediate group and the low group; the CHDs were classified as minor CHDs and major CHDs.

Ultrasound diagnosis of fetal intraspinal cysts in the third trimester.

Objective: To investigate the use of ultrasound to diagnose fetal intraspinal cyst in thethird trimester.

Method: A retrospective analysis of two cases of intraspinal cysts was performed. Theimaging characteristics of the two cysts were discussed.

The Diagnostic Value of 3D Power Doppler Ultrasound Combined With VOCAL in the Vascular Distribution of Breast Masses.

Rationale And Objectives: This study uses a three-dimensional energy Doppler technique combined with the Virtual Organ Computer-aided Analysis (VOCAL) method in order to determine the diagnostic threshold of blood flow index in breast tumors to provide a reference for evaluation and treatment options.

Materials And Methods: We collected 322 solid lesions which had been operated. Each lesion met the definite pathological diagnosis; collected lesions included 262 cases of benign lesions and 60 cases of malignant lesions.

Epidemiology of Dementia in Elderly Chronic Obstructive Pulmonary Disease Patients Living in China's Northwestern High-Elevation Area.

BACKGROUND The aim of this study was to investigate the effects of oxygen and cholinesterase inhibitor (donepezil) therapy on dementia in patients with age-exacerbated chronic obstructive pulmonary disease (COPD) in China's northwestern high-altitude area. MATERIAL AND METHODS A total of 145 patients with acute exacerbation of COPD admitted to the Gerontology Department of the First People's Hospital of Xining City were initially retrospectively screened. From among these 145 patients, we selected 33 cases with dementia and 33 patients without dementia through use of the Mini-Mental State Examination (MMSE), the Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog), and Activities of Daily Living (ADL) Scale evaluated before, 7 days after, and at the end of the treatment after 3 months.
