Frequent development of combined pituitary hormone deficiency in patients initially diagnosed as isolated growth hormone deficiency: a long term follow-up of patients from a single center.

BACKGROUND: Children initially diagnosed with isolated GH deficiency (IGHD) have a variable rate to progress to combined pituitary hormone deficiency (CPHD) during follow-up. OBJECTIVE: To evaluate the development of CPHD in a group of childhood-onset IGHD followed at a single tertiary center over a long period of time. PATIENTS AND METHODS: We retrospectively analyzed data from 83 patients initially diagnosed as IGHD with a mean follow-up of 15.2 years. The Kaplan-Meier method and Cox regression analysis was used to estimate the temporal progression and to identify risk factors to developme

Establishment and characterization of SUIT-58 pancreas cancer cell line and its subline S58-SF adapted to serum-free condition derived from metastatic liver tumor.

A new pancreas cancer cell line, SUIT-58, was established from metastatic liver tumor. The cultured cells exhibited polygonal shape, and proliferated in a form of sheet-structure showing prominent nucleoli and frequent mitotic features. Chromosome count ranged from 54 to 73 with modal chromosome numbers 72 and 73. It was noteworthy that this cell line grew in the serum-free media and maintained in this condition for 30 passages (designated as S58-SF). Both SUIT-58 and S58-SF cell lines were successfully transplanted into nude mice, and their tumor doubling times in xenografts were calculated a

Diffuse lymphoplasmacytic bronchiolitis in cartilage-hair hypoplasia.

Three children with cartilage-hair hypoplasia presented with chronic obstructive symptoms and bronchiolar wall thickening on high-resolution computed tomography scanning. In all children, surgical lung biopsy demonstrated diffuse dilated lymphoplasmacytic bronchiolitis. The bronchiolar wall was infiltrated by a lymphocyte sheath with plasma cell differentiation and dispersed secondary follicles. Clarithromycin substantially improved respiratory symptoms and pulmonary function, allowing children to return home.

New approaches to divorce with children: A problem of public health.

This broad review elaborates on the most up-to-date knowledge on biochemical and psychobiological aspects of parental loss and other childhood adversities during divorce involving minor children. So far, divorce involving minor children was unfortunately considered by authorities only as a purely juridical problem, and this approach has often allowed a completely different approach according to the Courts. Now, scientific research, also making use of animal models, is demonstrating the biological basis of the problem and the indisputable consequences on the well-being and health of children. T

6p subtelomere deletion with congenital glaucoma, severe mental retardation, and growth impairment.

Submicroscopic deletion of the 6p subtelomere has recently been recognized as a clinically identifiable syndrome. A distinct phenotype has emerged consisting of developmental delay/mental retardation, language impairment, hearing loss, and ophthalmologic, cardiac, and craniofacial abnormalities, including hypertelorism, midface hypoplasia, small nose, and high arched palate. We describe here a patient with 6p subtelomere deletion associated with congenital glaucoma, severe mental retardation, and growth impairment. Fluorescent in situ hybridization analysis revealed only one 6p25.3 signal. Arr

Phenotype in X chromosome rearrangements: pitfalls of X inactivation study.

OBJECTIVE: X inactivation pattern in X chromosome rearrangements usually favor the less unbalanced cells. It is correlated to a normal phenotype, small size or infertility. We studied the correlation between phenotype and X inactivation ratio in patients with X structural anomalies. PATIENTS AND METHODS: During the 1999-2005 period, 12 X chromosome rearrangements, including three prenatal cases, were diagnosed in the Laboratoire de Cytogénétique of Strasbourg. In seven cases, X inactivation ratio could be assessed by late replication or methylation assay. RESULTS: In three of seven cases (de

Clinical features in 27 patients with Angelman syndrome resulting from DNA deletion.

We report the clinical features in 27 Australasian patients with Angelman syndrome (AS), all with a DNA deletion involving chromosome 15(q11-13), spanning markers from D15S9 to D15S12, about 3 center dot 5 Mb of DNA. There were nine males and 18 females. All cases were sporadic. The mean age at last review (end of 1994) was 11 center dot 2 years (range 3 to 34 years). All patients were ataxic, severely retarded, and lacking recognisable speech. In all patients, head circumference (HC) at birth was normal but skewed in distribution, with 62 center dot 5% at the 10th centile. At last review HC w

Manifestations of systemic disease in the retina and fundus of cats and dogs.

The fundus is unique in that it is the only part of the body that allows for a noninvasive and uninterrupted view of vasculature and nervous tissue. Utilization of this can be a powerful tool in uncovering salient incidental findings which point to underlying systemic diseases, and for monitoring response to therapy. Retinal venules and arterioles allow the clinician to assess changes in vascular color, diameter, outline, and tortuosity. The retina and optic nerve may exhibit changes associated with increased or decreased thickness, inflammatory infiltrates, hemorrhages, and detachments. While

A prospective study revealing the role of an immune-related eRNA, WAKMAR2, in breast cancer.

Enhancer RNAs (eRNAs) are a subclass of non-coding RNAs that are generated during the transcription of enhancer regions and play an important role in tumourigenesis. In this study, we focused on the crucial eRNAs that participate in immune responses in invasive breast cancer (IBC). We first used The Cancer Genome Atlas and Human enhancer RNA Atlas to screen for tissue-specific eRNAs and their target genes. Through Pearson correlation analysis with immune genes, the eRNA WAKMAR2 was identified as a key candidate involved in IBC. Our further research suggested that WAKMAR2 is crucial in regulati

Loss-of-function and gain-of-function mutations in PPP3CA cause two distinct disorders.

Calcineurin is a calcium (Ca2+)/calmodulin-regulated protein phosphatase that mediates Ca2+-dependent signal transduction. Here, we report six heterozygous mutations in a gene encoding the alpha isoform of the calcineurin catalytic subunit (PPP3CA). Notably, mutations were observed in different functional domains: in addition to three catalytic domain mutations, two missense mutations were found in the auto-inhibitory (AI) domain. One additional frameshift insertion that caused premature termination was also identified. Detailed clinical evaluation of the six individuals revealed clinically un

Mutations in the TGFβ binding-protein-like domain 5 of FBN1 are responsible for acromicric and geleophysic dysplasias.

Geleophysic (GD) and acromicric dysplasia (AD) belong to the acromelic dysplasia group and are both characterized by severe short stature, short extremities, and stiff joints. Although AD has an unknown molecular basis, we have previously identified ADAMTSL2 mutations in a subset of GD patients. After exome sequencing in GD and AD cases, we selected fibrillin 1 (FBN1) as a candidate gene, even though mutations in this gene have been described in Marfan syndrome, which is characterized by tall stature and arachnodactyly. We identified 16 heterozygous FBN1 mutations that are all located in exons

The phenotype caused by PYCR1 mutations corresponds to geroderma osteodysplasticum rather than autosomal recessive cutis laxa type 2.

Geroderma osteodysplasticum is a rare autosomal recessive disorder characterized by wrinkled skin on the dorsum of the hands and feet, osteopenia, prognathism, and an elongated and lax face. The mutated gene was identified as GORAB (SCYL1BP1). As well, the PYCR1 gene also was shown to be mutated in a similar disease, designated cutis laxa, autosomal recessive, type IIB (ARCL2B) or cutis laxa with progeroid features. We describe here the clinical findings in four affected individuals in a family with geroderma osteodysplasticum with mental retardation and a homozygous mutation in PYCR1. Althoug

Medically underserved girls receive less evaluation for short stature.

OBJECTIVE: To determine if gender is associated with diagnostic evaluation by primary care pediatricians caring for children with growth-faltering. PATIENTS AND METHODS: This was a retrospective study of children who were attending 4 urban pediatric primary care practices affiliated with a tertiary pediatric hospital. Growth-faltering was defined as height at the <5th percentile or a z-score decrease of ≥ 1.5 SDs before 18 months of age or ≥ 1 SD thereafter. For each child, height z score, age, gender, race, insurance, diagnostic tests, and subspecialist appointments were examined. RESULTS:
