Sitagliptin is selective dipeptidyl peptidase-4 inhibitor (DPP4-I), used clinically as a new oral anti-diabetic agent. This study explored the underlying mechanisms of the hepatoprotective role of sitagliptin pretreatment against methotrexate (MTX) induced hepatotoxicity in mice. Forty mice were divided into four groups (10 mice each); control, MTX, and two sitagliptin groups (pretreated with sitagliptin 10 and 20 mg/kg/day, respectively) for five consecutive days prior to MTX injection. Results showed that MTX induced marked hepatic injury in the form of cloudy swelling, hydropic degeneration, apoptosis and focal necrosis in all hepatic zones...

INTRODUCTION: Recently, the semi-quantitative ratio grading for endolymphatic hydrops (EH) was found as none specific of MD because all healthy subjects referred with at least one hydrops location with this grading method and 3D-FLAIR sequence. The objectives of this study were to assess the EH prevalence in MD using both the semi-quantitative ratio method of grading and the Saccule to Utricle Ration Inversion (SURI) technique with two 3D-FLAIR sequences, closely similar except for the inversion time of the sequence...

Corneal hydrops affects approximately 2.5% of keratoconus (KC) cases, predominantly young males approximately 25 years of age with steep cones. Often, patients are left with a vision-reducing corneal scar frequently necessitating surgical treatment. Penetrating keratoplasty (PK) has worse survival outcomes in hydrops than in general KC cases. Deep anterior lamellar keratoplasty (DALK) is a nonpenetrating technique believed to achieve equal or better outcomes in visual acuity, graft survival, endothelial rejection rates, and endothelial cell survival in comparison with PK, while maintaining globe integrity and the patients' Descemet membrane (DM) and endothelium...

We describe the case of a 33-week preterm infant who developed nonimmune hydrops fetalis secondary to a kaposiform hemangioendothelioma (KHE). The tumor was successfully treated with vincristine, prednisone, ticlopidine, and aspirin. KHE can be an unusual cause of hydrops fetalis; in such cases, diagnosis can be challenging since generalized edema can obscure KHE.

Immunodysregulation, Polyendocrinopathy, Enteropathy, X-linked (IPEX) syndrome is a rare, X-linked recessive disease that affects regulatory T cells (Tregs) resulting in diarrhea, enteropathy, eczema, and insulin-dependent diabetes mellitus. IPEX syndrome is caused by pathogenic alterations in FOXP3 located at Xp11.23. FOXP3 encodes a transcription factor that interacts with several partners, including NFAT and NF-κB, and is necessary for the proper cellular differentiation of Tregs. Although variable, the vast majority of IPEX syndrome patients have onset of disease during infancy with severe enteropathy...

BACKGROUND: Large mediastinal teratomas in the fetus are rare and can present with direct compression of intrathoracic structures as well as pericardial and pleural effusions. Mediastinal fetal teratoma may be detected as a mass in the chest during a routine prenatal ultrasound. Because of the pressure on mediastinal structures it may result in non-immune fetal hydrops and polyhydramnios. The development of hydrops may lead to fetal demise. Timely obstetric and surgical removal is important to improve survival in this patient population...

BACKGROUND: The Doppler measurement of middle cerebral artery peak systolic velocity (MCA-PSV) is considered the gold standard for the noninvasive detection of moderate to severe anemia. However, the accuracy of this test has not been evaluated so far, specifically beyond 34 weeks. OBJECTIVES: To assess the accuracy of MCA-PSV to detect moderate to severe fetal anemia and to identify risk factors associated with false-positive and false-negative MCA-PSV values after 34 weeks...

Hemolytic disease of the fetus and newborn (HDFN) remains a serious pregnancy complication which can lead to severe fetal anemia, hydrops and perinatal death. Areas covered: This review focusses on the current prenatal management, treatment with intrauterine transfusion (IUT) and promising non-invasive treatment options for HDFN. Expert commentary: IUTs are the cornerstone in prenatal management of HDFN and have significantly improved perinatal outcome in the past decades. IUT is now a relatively safe procedure, however the risk of complications is still high when performed early in the second trimester...

Placental mesenchymal dysplasia is an increasingly recognizable abnormality. Early cases have been confused with partial hydatidiform mole. Placental mesenchymal dysplasia is probably under-diagnosed because of being an unfamiliar clinical entity and also mistaken for gestational trophoblastic disease due to the similar sonographic findings of two entities. In this report, we describe the clinical, gross, and histopathological findings of placental mesenchymal dysplasia in two cases. The 33-week-preterm baby of a 26-year-old woman with cardiovascular disease and 342 gram placenta and the 19-week fetus with trisomy 21 of a 40 year-old woman were terminated...

Recently, in vivo visualization of the cochlea and the smaller structures inside of it has been achieved by optical coherence tomography (OCT). This makes it possible to use OCT imaging for diagnosis of diseases such as Meniere's disease through measuring the degree of endolymphatic hydrops. To this end, we present a novel method for 3D segmentation of these cochlear OCT images that is based on superpixels and diffusion maps. The method takes as input grayscale volumetric OCT images and outputs a binary image with the segmented cochlea...

REVIEW
Bridget B Zoeller
Fetal arrhythmia is a common reason for referral to fetal cardiology. Fetal supraventricular tachycardia can be subdivided into several groups with the most common being re-entrant supraventricular tachycardia and atrial flutter. Fetal tachycardia can lead to hydrops fetalis, which increases the risk of fetal demise, perinatal morbidities, and premature delivery. The diagnosis of fetal tachycardia can be a challenge as a traditional electrocardiogram cannot be completed on a fetus, and other methods must be used by fetal echocardiogram...

Congenital pulmonary lymphangiectasia (CPL) is a rare but fatal disease, usually having an onset from the first few hours to days after birth. Inconsistent nomenclatures were used for CPL in the past decades. Patients often present with intractable respiratory failure, hydrops fetalis and even sudden death. The etiologies of CPL remain unclear. Previous hypotheses suggested that CPL might be caused by conditions preventing normal regression of the lymphatics after the 18th-20th week of gestation. Up-to-date biological studies on lymphatic development, lymphatic valve formation and occurrence of hydrops fetalis revealed possible causative relations with mutations of genes of the vascular endothelial growth factor receptor (VEGFR), RAS/MAPK, PI3K/AKT and NF-κB signaling pathways...

A 49-year-old man with no previous history of musculoskeletal or cutaneous problems who had a myocardial infarction (MI) was treated with atorvastatin, prasugrel, enoxaparine, and diltiazem following percutaneous coronary intervention. He was referred to our rheumatology outpatient clinic for rash and papules on the knuckles, face, and neck, as well as proximal muscle weakness. In the physical examination, a reddish rash on the face and Gottron's papules on the knuckles were detected. The skin biopsy performed indicated interface dermatitis with hydropic degeneration of basal keratinocytes, supporting the clinical impression of dermatomyositis...

Zinc oxide nanoparticles (ZnO NPs) are widely used in industry and cosmetic products with promising investment in medical diagnosis and treatment. However, these particles may reveal a high potential risk for human health with no information about hepatotoxicity that might be associated with their exposure. The present work was carried out to investigate the histological and histochemical alterations induced in the hepatic tissues by naked 35nm ZnO NPs. Male Wistar albino rats were exposed to ZnO NPs at a daily dose of 2mg/kg for 21days...

BACKGROUND: Keratoconus may progress to acute corneal hydrops even after cross-linking. In some cases, keratoconus progresses during pregnancy. In this report, we present a case of a patient with increased anterior stromal resistance after cross-linking that would favor nonprogression of keratoconus during pregnancy. CASE PRESENTATION: We report that cross-linking is likely to have had a protective effect in a white pregnant patient with acute corneal hydrops who showed rapid improvement, as documented by corneal topography...
