PurposeThe application of genomic sequencing to investigate unexplained death during early human development, a form of lethality likely enriched for severe Mendelian disorders, has been limited.MethodsIn this study, we employed exome sequencing as a molecular autopsy tool in a cohort of 44 families with at least one death or lethal fetal malformation at any stage of in utero development. Where no DNA was available from the fetus, we performed molecular autopsy by proxy, i.e., through parental testing.ResultsPathogenic or likely pathogenic variants were identified in 22 families (50%), and variants of unknown significance were identified in further 15 families (34%)...

Objective: Exopolysaccharides gained attention as new source for cancer treatment as recent treatments cause side effects and multidrug resistance. Polysaccharides containing sulfur and uronic acids exhibited antioxidant activity, by restoring cell redox regulation, thus inhibiting cell proliferation and cancer formation. Following this context, our study was performed to assess the cytotoxic activity of exopolysaccharides produced by novel Egyptian marine bacterial strains on HepG2 cells. Methods: Bacteria were isolated, purified and cultured through routine microbiological techniques...

Hypocomplementic urticarial vasculitis syndrome (HUVS) is an autoimmune disease characterized by recurrent urticaria, arthritis, and glomerulonephritis (GN). Anti-C1q antibody is the marker of HUVS together with low levels of classical pathway complements which are C2, C3, C4, and C1q. We report a case of a 6-year-old boy who presented with episodes of rashes, injected conjunctiva, abdominal pain, and arthritis, diagnosed as HUVS. He had low C3, low CH50, normal C4, and positive C1q antibody. His urinalysis showed intermittent microscopic hematuria only...

Prevalence, clinicopathological features, and outcome of childhood idiopathic steroid-resistant nephrotic syndrome (ISRNS) vary in different countries. We report on these parameters in a single center in Khartoum. We retrospectively reviewed all the records of children with idiopathic nephrotic syndrome (INS) followed up in the pediatric renal unit, Soba Hospital, Khartoum between 2001 and 2012. ISRNS was defined as no remission within four weeks of daily prednisolone at a dose of 60 mg/m2. In 430 children with INS 130 (28%) had SRNS with a mean age of 7...

Vici syndrome is one of the most extensive inherited human multisystem disorders and due to recessive mutations in EPG5 encoding a key autophagy regulator with a crucial role in autophagosome-lysosome fusion. The condition presents usually early in life, with features of severe global developmental delay, profound failure to thrive, (acquired) microcephaly, callosal agenesis, cataracts, cardiomyopathy, hypopigmentation, and combined immunodeficiency. Clinical course is variable but usually progressive and associated with high mortality...

Due to new European legislation, products going to waste are subject to "low persistent organic pollutant concentration limits". Concentrations of restricted brominated flame retardants in waste products must be determined. A rapid extraction and clean-up method was developed for determination of brominated flame retardants in various plastics and textiles. The optimised method used vortexing and ultrasonication in dichloromethane followed by sulfuric acid clean-up to determine target compounds. Polybrominated diphenyl ethers were determined by gas chromatography with mass spectrometry and hexabromocyclododecane by liquid chromatography with tandem mass spectrometry...

AIM: Afferent arterioles (AA) hold a key position in the regulation of renal blood flow and glomerular filtration rate. Being the effector site of tubuloglomerular feedback the afferent arteriole contributes to the renal handling of sodium and fluid. Dehydration goes along with increased renal interstitial protein concentration. Here, the hypothesis was tested that extravasal protein concentration directly modulates afferent arteriolar tone; a mechanism which may contribute to body fluid volume control...

Histological procedures aim at providing good-quality sections that can be used for a light microscopic evaluation of tissue. These are applicable to identify either spontaneous or diseases-induced changes. Routinely, tissues are fixed with neutral formalin 10%, embedded in paraffin, and manually sectioned with a microtome to obtain 4-5 μm thick paraffin sections. Dewaxed sections are then stained with HE&S (hematoxylin-eosin and saffron) or can be used for other purposes (special stains, immunohistochemistry, in situ hybridization, etc...

Necropsy is a major step of most studies using laboratory animals. During necropsy, tissue and organ noticeable grossly changes should be recorded and critical tissue samples may be stored for the subsequent evaluation. It is therefore important that the personnel in charge of this key experimental step to be adequately trained and aware of the study endpoints.

Chondroblastic osteosarcoma, representing about 25% of osteosarcoma, is a fatal primary malignancy of the skeleton if not diagnosed and treated appropriately. It most commonly occurs in the long bones of the extremities near the metaphyseal growth plates. In this report, we describe the occurrence of chondroblastic osteosarcoma involving the left distal tibia in a 14-year-old male. The diagnosis was confirmed by the histological examination of a surgical biopsy. The patient was treated by both surgery and neoadjuvant chemotherapy...

BACKGROUND: Severe combined immunodeficiency (SCID) is fatal unless treated with hematopoietic stem cell transplant. Delay in diagnosis is common without newborn screening. Family history of infant death due to infection or known SCID (FH) has been associated with earlier diagnosis. OBJECTIVE: The aim of this study was to identify the clinical features that affect age at diagnosis (AD) and time to the diagnosis of SCID. METHODS: From 2005 to 2016, 147 SCID patients were referred to the Asian Primary Immunodeficiency Network...

A 2-year-old boy presented profound developmental delay, failure to thrive, ataxia, hypotonia and tonic-clonic seizures that caused the death of the patient. Targeted and whole-exome sequencing revealed two heterozygous missense variants: a novel mutation in KCNJ10 gene that encodes for the inwardly-rectifying K(+) channel Kir4.1 and another previously characterized mutation in KCNT1 that encodes for the Na(+)-activated K(+) channel known as Slo2.2 or SLACK. The objectives of this study were to perform the clinical and genetic characterization of the proband and his family and to examine the functional consequence of the Kir4...
