    Li-Fraumeni syndrome (LFS) is a cancer predisposition syndrome caused by a germline mutation of the TP53 gene on chromosome 17p13.1. It has an autosomal dominant pattern of inheritance with high penetrance. These patients have a very high lifetime cumulative risk of developing multiple malignancies and have a strong family history of early-onset malignancies. The protein p53, encoded by TP53, has a complex set of genome-preserving functions initiated during episodes of cellular stress and DNA damage. In LFS, TP53 gene mutations cause the loss of function of p53, leading to downstream events permissive for development of various malignancies throughout life. The LFS component tumors include soft tissue sarcomas, osteosarcoma, premenopausal breast cancer, brain tumors, and adrenal cortical carcinomas. Multiple types of sarcomas have been reported in association with LFS; this review article will focus on the most frequently encountered pediatric sarcomas associated with TP53 mutations.

    The Li-Fraumeni syndrome is characterized clinically by the appearance of tumors in multiple organs generally at an early age. This hereditary condition is caused by germinal mutations in the TP53 gene, which codifies for the tumoural suppressor gene p53. We present the case of a patient aged 31 with clinical and molecular diagnosis of Li-Fraumeni syndrome who presented two synchronous tumors: a leiomyosarcoma on the forearm and a phyllodes breast tumour. She had a family history of cancer, including a son diagnosed with a cortical adrenal carcinoma when he was three years old, who died at five from the disease. Furthermore, her maternal grandmother and great-grandmother died of stomach cancer at 56 and 60 years old, respectively, while her other great-grandmother and a great aunt presented with breast cancer at the ages of 60 and 40, respectively. After genetic counseling, complete sequencing and analysis of duplications and deletions in the TP53 gene were ordered prior to diagnosis. The molecular analysis of a DNA sample taken from peripheral blood lymphocytes revealed the germinal mutation c.527G>T (p.Cys176Phe) on exon 5 of the TP53 gene, a deleterious mutation described previously in tumoural tissues. To our knowledge, this is the first published case in Colombia of Li-Fraumeni syndrome with confirmed molecular diagnosis. The diagnosis and management of Li-Fraumeni syndrome should be performed by a multidisciplinary team, and genetic counselling should be offered to patients and their relatives.

    Li-Fraumeni Syndrome (LFS) is an autosomal dominant genetic disorder associated with mutations in the TP53 gene and characterized by a propensity to develop a variety of malignancies resulting in a shortened lifespan. We report a case of prostate cancer in a 50 year old male with LFS. Experimental studies suggest that TP53 mutations in prostate cancer are associated with therapeutic resistance to radiation, chemotherapy, and anti-androgens, implying that LFS men may experience more aggressive cancer biology with implications for therapeutic decisions. The potential of prostate cancer to develop earlier in LFS favors institution of screening at earlier ages. PMID:26793489

    Li-Fraumeni syndrome (LFS) is a rare dominantly inherited cancer predisposition syndrome that was first described in 1969. In most families, it is caused by germline mutations in the TP53 gene and is characterized by early onset of multiple specific cancers and very high lifetime cumulative cancer risk. Despite significant progress in understanding the molecular biology of TP53, the optimal clinical management of this syndrome is poorly defined. We convened a workshop on November 2, 2010, at the National Institutes of Health in Bethesda, Maryland, bringing together clinicians and scientists, as well as individuals from families with LFS, to review the state of the science, address clinical management issues, stimulate collaborative research, and engage the LFS family community. This workshop also led to the creation of the Li-Fraumeni Exploration (LiFE) Research Consortium. PMID:22939227

    Background: Li-Fraumeni syndrome (LFS) is one of the most serious hereditary cancer syndromes with a high risk of malignancy in childhood. This syndrome is an autosomal dominant cancer predisposing syndrome due to a germline mutation in the TP53 tumor suppressor gene. Methods: In this study, a representative family case of Li-Fraumeni syndrome is described. The proband of this family was a 43-year-old male who had osteosarcoma of the mandible and a positive family history of cancer. His mother died at the age of 29 of brain cancer; his sister died at the age of 18 of breast cancer; his brother died at the age of 36 of liver cancer; and another sister of his died at the age of 16 of leukemia. Complete sequence analysis of the TP53 and PTEN genes was performed in this family. We used standard diagnostic tools such as sequencing and multiplex ligation-dependent probe amplification (MLPA) to analyze these two genes in this family. The exons and flanking exon-intron junctions of the TP53 and PTEN genes were sequenced. Results: We detected a germline mutation in the TP53 gene in this family that was previously reported as somatic mutation in LFS in the catalogue of somatic mutations in cancer (COSMIC). In addition, according to the International Agency for Research of Cancer (IARC) database, a 19-year-old male patient with sarcoma was recently reported to have this germline mutation. We also found two new IVS variations in the PTEN gene, one of which can be a suggestive evidence of an effect on the splicing of PTEN. Conclusion: Genomic modifications for tumor risk and genotype-phenotype correlations in LFS are still to be identified. We believe every new finding in this area can provide new insights into the pathogenesis and progression of Li-Fraumeni syndrome. PMID:27493922

    Li Fraumeni syndrome (LFS) is a rare familial cancer predisposition syndrome with autosomal-dominant inheritance, occurring as frequently as one in 5,000–20,000 individuals. However, no LFS case has been reported from mainland China although it constitutes one quarter of population on earth. In this study, we identified, to our best knowledge, the first Li Fraumeni syndrome family in China. Six family members were affected with various tumors. A TP53 mutation (c.730G > A; p.G244S) co-segregated with the tumor phenotype within this family. Functional analysis indicated that G244S mutation disrupted the transactivity, DNA-binding and cell growth inhibition activity of p53 protein. Two available tumor samples (medulloblastoma and choroid plexus papilloma) underwent large rearrangement in the chromosomes and loss of wild-type TP53. Our data warranted further studies on the prevalence of germline TP53 mutation in various tumor patients in China. PMID:26818906

    Li-Fraumeni Syndrome (LFS) is a rare autosomal dominant familial cancer syndrome, characterized by multiple malignancies and frequent germline alterations in TP53. In this study, we highlight four unclassified exonic TP53 variants detected in patients with a suspected diagnosis of LFS. Most intriguing was the discovery of a "super-transactivation" variant within Exon 10 of TP53 (c.1079G>T/p.G360V). Functional analysis of this novel variant revealed a paradoxical "super-transactivation" effect on tp53 response elements and a corresponding tumor suppressive effect on colony formation and apoptosis. While unlikely to be disease-causing, we propose that this variant may represent a novel tp53 polymorphism and potential phenotypic modifier in LFS. In the future, the enhanced transactivation effects of p.G360V-tp53 may also prove useful in designing more efficacious tp53-based gene therapies. PMID:27297285

    Li Fraumeni Syndrome (LFS) is a hereditary cancer syndrome characterized by a high risk of developing various types of cancer from birth through late adulthood. Clinical benefits of surveillance for LFS are limited. The aim of this study is to investigate which advice for regular surveillance, if any, is given to high risk LFS individuals, adherence to that advice, and any psychological gain or burden derived from surveillance. Fifty-five high risk individuals (proven carriers and those at 50% risk) from families with a p53 germline mutation were invited to participate, of whom 82% completed a self-report questionnaire assessing advice for regular surveillance, compliance, perceived benefits and barriers of screening and LFS-related distress (IES) and worries (CWS). In total, 71% of the high risk family members received advice to undergo regular surveillance for LFS. The majority (78%) reported adherence with the recommended advice. All high risk women aged 25 or older reported having been advised to undergo annual breast cancer surveillance (n = 11), of whom 64% (n = 7) in specific received advice to undergo a mammography. Seventy-eight percent of respondents indicated having received tailored surveillance advice based on family cancer history. The large majority of respondents believed in the value of surveillance to detect tumors at an early stage (90%) and reported that it gave them a sense of control (84%) and security (70%). Despite its limited clinical benefits, the majority of high risk LFS family are advised to undergo, and are adherent to, and report psychological benefit from, regular surveillance programs.

  13. Primed for cancer: Li Fraumeni Syndrome and the pre-cancerous niche

    The complex relationship between tumour and stroma is still being elucidated but it is clear that cancer is a disease of more than just malignant cells. However, the dominant focus of our current understanding of Li Fraumeni Syndrome (LFS) remains on the function of p53 as ‘guardian of the genome’. Recent evidence shows that the TP53 gene is at the nexus of a wider range of functions, including aspects of cellular metabolism, aging and immunity. Incorporating this broader picture of the role of TP53 together with our understanding of the role of the host microenvironment in cancer initiation and progression gives a more nuanced picture of LFS. Furthermore, there is clinical evidence to suggest that the host environment in healthy individuals with LFS already includes some of the features of a ‘pre-cancerous niche’ that makes cancer initiation more likely. It is suggested, finally, that there are pharmacological interventions capable of altering this pre-cancerous niche, thus potentially reducing the cancer risk in individuals with LFS. PMID:26082798

    Germ-line mutations of the tumor-suppressor gene p53 have been observed in some families with the Li-Fraumeni syndrome (LFS), a familial cancer syndrome in which affected relatives develop a diverse set of early-onset malignancies including breast carcinoma, sarcomas, and brain tumors. The analysis of the p53 gene in LFS families has been limited, in most studies to date, to the region between exon 5 and exon 9. In order to determine the frequency and distribution of germ-line p53 mutations in LFS, we sequenced the 10 coding exons of the p53 gene in lymphocytes and fibroblast cell lines derived from 14 families with the syndrome. Germ-line mutations were observed in eight families. Six mutations were missense mutations located between exons 5 and 8. One mutation was a nonsense mutation in exon 6, and one mutation was a splicing mutation in intron 4, generating aberrant shorter p53 RNA(s). In three families, a mutation of the p53 gene was observed in the fibroblast cell line derived from the proband. However, the mutation was not found in affected relatives in two families and in the blood from the one individual, indicating that the mutation probably occurred during cell culture in vitro. In four families, no mutation was observed. This study indicates that germ-line p53 mutations in LFS are mostly located between exons 5 and 8 and that {approximately}50% of patients with LFS have no germ-line mutations in the coding region of the p53 gene. The observation of p53 mutations occurring during primary cultures of human fibroblasts shows that analysis for germ-line p53 mutations must be performed on cells that have not been grown in vitro. 49 refs., 1 fig., 4 tabs.

    Somatic mutations of TP53 are among the most common in cancer and germline mutations of TP53 (usually missense) can cause Li-Fraumeni syndrome (LFS). Recently, recurrent genomic rearrangements in intron 1 of TP53 have been described in osteosarcoma (OS), a highly malignant neoplasm of bone belonging to the spectrum of LFS tumors. Using whole-genome sequencing of OS, we found features of TP53 intron 1 rearrangements suggesting a unique mechanism correlated with transcription. Screening of 288 OS and 1,090 tumors of other types revealed evidence for TP53 rearrangements in 46 (16%) OS, while none were detected in other tumor types, indicating this rearrangement to be highly specific to OS. We revisited a four-generation LFS family where no TP53 mutation had been identified and found a 445 kb inversion spanning from the TP53 intron 1 towards the centromere. The inversion segregated with tumors in the LFS family. Cancers in this family had loss of heterozygosity, retaining the rearranged allele and resulting in TP53 expression loss. In conclusion, intron 1 rearrangements cause p53-driven malignancies by both germline and somatic mechanisms and provide an important mechanism of TP53 inactivation in LFS, which might in part explain the diagnostic gap of formerly classified “TP53 wild-type” LFS.

    Li-Fraumeni syndrome (LFS) patients harbor germ line mutations in the TP53 gene and are at increased risk of hormone receptor-positive breast cancers. Recently, elevated levels of aromatase, the rate-limiting enzyme for estrogen biosynthesis, were found in the breast tissue of LFS patients. Although p53 down-regulates aromatase expression, the underlying mechanisms are incompletely understood. In the present study, we found that LFS stromal cells expressed higher levels of Hsp90 ATPase activity and aromatase compared with wild-type stromal cells. Inhibition of Hsp90 ATPase suppressed aromatase expression. Silencing Aha1 (activator of Hsp90 ATPase 1), a co-chaperone of Hsp90 required for its ATPase activity, led to both inhibition of Hsp90 ATPase activity and reduced aromatase expression. In comparison with wild-type stromal cells, increased levels of the Hsp90 client proteins, HIF-1α, and PKM2 were found in LFS stromal cells. A complex comprised of HIF-1α and PKM2 was recruited to the aromatase promoter II in LFS stromal cells. Silencing either HIF-1α or PKM2 suppressed aromatase expression in LFS stromal cells. CP-31398, a p53 rescue compound, suppressed levels of Aha1, Hsp90 ATPase activity, levels of PKM2 and HIF-1α, and aromatase expression in LFS stromal cells. Consistent with these in vitro findings, levels of Hsp90 ATPase activity, Aha1, HIF-1α, PKM2, and aromatase were increased in the mammary glands of p53 null versus wild-type mice. PKM2 and HIF-1α were shown to co-localize in the nucleus of stromal cells of LFS breast tissue. Taken together, our results show that the Aha1-Hsp90-PKM2/HIF-1α axis mediates the induction of aromatase in LFS. PMID:27467582

    This study presents findings of a mixed-method descriptive exploration of the role of friends and spirituality/religiosity in easing the burden of families with the rare inherited disorder, Li-Fraumeni Syndrome (LFS). LFS is caused by germline mutations in the TP53 gene and is associated with very high lifetime risk of developing one or more malignancies. During the first clinical visit we assessed several types of social support among a subset of study participants (N = 66) using an established interactive research tool called the Colored Eco-Genetic Relationship Map (CEGRM). We performed both quantitative and qualitative analyses of social relationships with LFS family members and close non-kin. Distress scores (N = 59) were mostly low normal, with some outliers. We found that reported friendships varied widely, that the friendships were often deep and enduring, and were important sources of informational, tangible, emotional and spiritual support. Confidantes tended to be best friends and/or spouses. Organized religion was important in selected families, typically from mainstream traditions. However, a number of people identified themselves as "spiritual" and reported spiritual and humanist explorations. Our results shed preliminary light on how some people in families with LFS cope in the face of tremendous medical, social and emotional challenges. PMID:26621765

    Li-Fraumeni syndrome is a rare cancer predisposition syndrome classically associated with remarkably early onset of cancer in families with a typical spectrum of malignancies, including sarcoma, breast cancer, brain tumors, and adrenocortical carcinoma. Because the risks of cancer development are strikingly high for Li-Fraumeni syndrome, aggressive cancer surveillance is often pursued in these individuals. However, optimal screening methods and intervals for Li-Fraumeni syndrome have yet to be determined. In addition, there may be a significant psychosocial burden to intensive cancer surveillance and some prevention modalities. Here, we describe a case of a young woman with a de novo mutation in TP53 and multiple malignancies, with her most recent cancers found at early, curable stages due to aggressive cancer screening. The potential benefits and risks of intensive cancer surveillance in hereditary cancer syndromes is discussed. PMID:26029016

    Objectives Li Fraumeni syndrome is an autosomal dominant cancer syndrome due to a germline mutation in the p53 tumor suppressor gene. It results in multiple primary neoplasms in children and adults. A common question when faced with a Li Fraumeni patient who develops multiple primary cancers and/or recurrences is what is the proper treatment? Data suggests that ionizing radiation exposure increases the incidence of second malignancies in the Li Fraumeni population. Therefore, how much surgery can a cancer patient tolerate and still derive benefit from it? Methods We describe a representative case of a 54 year old female with Li Fraumeni syndrome with an enlarging adrenocortical hepatic metastasis, a new primary ampullary cancer, and an extensive surgical history. Results We performed a simultaneous pancreaticoduodenectomy and repeat partial hepatectomy. Conclusions We propose that surgery is under utilized in metastatic solid organ familial cancers in general, and argue that an aggressive surgical approach should be considered in a multidisciplinary fashion for patients with Li Fraumeni syndrome and recurrent tumors. However, because of the rarity of this familial cancer there is a paucity of evidence to support this approach therefore a review of the literature is presented. PMID:23563208

    The Li-Fraumeni syndrome (LFS) and its variant form (LFL) is a familial predisposition to multiple forms of childhood, adolescent, and adult cancers associated with germ-line mutation in the TP53 tumor suppressor gene. Individual disparities in tumor patterns are compounded by acceleration of cancer onset with successive generations. It has been suggested that this apparent anticipation pattern may result from germ-line genomic instability in TP53 mutation carriers, causing increased DNA copy-number variations (CNVs) with successive generations. To address the genetic basis of phenotypic disparities of LFS/LFL, we performed whole-genome sequencing (WGS) of 13 subjects from two generations of an LFS kindred. Neither de novo CNV nor significant difference in total CNV was detected in relation with successive generations or with age at cancer onset. These observations were consistent with an experimental mouse model system showing that trp53 deficiency in the germ line of father or mother did not increase CNV occurrence in the offspring. On the other hand, individual records on 1,771 TP53 mutation carriers from 294 pedigrees were compiled to assess genetic anticipation patterns (International Agency for Research on Cancer TP53 database). No strictly defined anticipation pattern was observed. Rather, in multigeneration families, cancer onset was delayed in older compared with recent generations. These observations support an alternative model for apparent anticipation in which rare variants from noncarrier parents may attenuate constitutive resistance to tumorigenesis in the offspring of TP53 mutation carriers with late cancer onset.

    The radiation response of Epstein-Barr virus (EBV)-immortalised lymphoblastoid cell lines derive from Li-Fraumeni syndrome (LFS) and LFS-like individuals was investigated. Cells from all LFS and LFS-like cases showed an accumulation of p53 protein following 137Cs gamma-irradiation, which was associated with cell cycle arrest at the G1/S border. This response was indistinguishable from that seen in cells derived from normal individuals, and occurred in cases with missense mutations in the TP53 gene at codons 175, 180, 220 and 248 and also in two LFS-like individuals with no TP53 mutation. Previous studies using lymphocytes and fibroblasts from LFS individuals have demonstrated abnormal radiation responses in these cells. This suggest cell type specificity in the contribution of a mutant p53 protein to phenotype. Images Figure 1 Figure 4 PMID:8795570

    Non-malignant dermal fibroblast strains, cultured from affected members of a Li-Fraumeni syndrome (LFS) family with diverse neoplasms associated with radiation exposure, display a unique increased resistance to the lethal effects of gamma-radiation. In the studies reported here, this radioresistance (RR) trait has been found to correlate strongly with an abnormal pattern of post-gamma-ray DNA replicative synthesis, as monitored by radiolabelled thymidine incorporation and S-phase cell autoradiography. In particular, the time interval between the gamma-ray-induced shutdown of DNA synthesis and its subsequent recovery was greater in all four RR strains examined and the post-recovery replication rate was much higher and was maintained longer than in normal and spousal controls. Alkaline sucrose sedimentation profiles of pulse-labelled cellular DNA indicated that the unusual pattern of DNA replication in irradiated RR strains may be ascribed to anomalies in both replicon initiation and DNA chain elongation processes. Moreover, the RR strain which had previously displayed the highest post-gamma-ray clonogenic survival was found to harbour a somatic (codon 234) mutation (presumably acquired during culture in vitro) in the same conserved region of the p53 tumour-suppressor gene as the germline (codon 245) mutation in the remaining three RR strains from other family members, thus coupling the RR phenotype and abnormal post-gamma-ray DNA synthesis pattern with faulty p53 expression. Significantly, these two aberrant radioresponse end points, along with documented anomalies in c-myc and c-raf-1 proto-oncogenes, are unprecedented among other LFS families carrying p53 germline mutations. We thus speculate that this peculiar cancer-prone family may possess in its germ line a second, as yet unidentified, genetic defect in addition to the p53 mutation. Images Figure 8 PMID:7779715

    Cancer genetics has rapidly evolved in the last two decades. Understanding and exploring the several genetic pathways in the cancer cell is the foundation of targeted therapy. Several genomic aberrations have been identified and their role in carcinogenesis is being explored. In contrast to most cancers where these mutations are acquired, patients with hereditary cancer syndromes have inherited genomic aberrations. The understanding of the molecular pathobiology in hereditary cancer syndromes has advanced dramatically. In addition, many molecularly targeted therapies have been developed that could have potential roles in the treatment of patients with hereditary cancer syndromes. In this review, we outline the presentation, molecular biology, and possible targeted therapies for two of the most widely recognized hereditary cancer syndromes -- hereditary breast and ovarian cancer syndrome and hereditary non-polyposis colorectal cancer syndrome (Lynch syndrome). We will also discuss other syndromes such as familial adenomatous polyposis and Li-Fraumeni syndrome (TP53). PMID:25549704

    Mutations of the IDH1 gene are frequent in gliomas, with R132H (CGT-->CAT) being the most common (>85%). In astrocytomas, IDH1 mutations are typically co-present with, or precede, TP53 mutations. We assessed IDH1 mutations in brain tumors diagnosed in patients from three families with Li-Fraumeni syndrome. We identified IDH1 mutations in five astrocytomas that developed in carriers of a TP53 germline mutation. Without exception, all were R132C (CGT-->TGT), which in sporadic astrocytomas accounts for <5% of IDH1 mutations. This remarkably selective occurrence of R132C mutations may reflect differences in the sequence of genetic events, with a preference for R132C mutations in astrocytes or precursor cells that already carry a germline TP53 mutation.

    In contrast to other tumor suppressor genes, the majority of TP53 alterations are missense mutations. We have previously reported that in the Li-Fraumeni syndrome (LFS), germline TP53 missense mutations are associated with an earlier age of tumor onset. In a larger series, we observed that mean age of tumor onset in patients harboring dominant negative missense mutations and clearly null mutations was 22.6 and 37.5 years, respectively. To assess the impact of heterozygous germline TP53 mutations in the genetic context of the patients, we developed a new functional assay of the p53 pathway on the basis of induction of DNA damage in Epstein-Barr-virus-immortalized lymphocytes, followed by comparative gene-expression profiling. In wild-type lymphocytes, we identified a core of 173 genes whose expression was induced more than twofold, of which 46 were known p53 target genes. In LFS lymphocytes with canonical missense mutations, the number of induced genes and the level of known p53 target genes induction were strongly reduced as compared with controls and LFS lymphocytes with null mutations. These results show that certain germline missense TP53 mutations, such as those with dominant negative effect, dramatically alter the response to DNA damage. This probably explains why TP53 alterations are predominantly missense mutations. PMID:23172776

    We describe two Li-Fraumeni syndrome families. Family A was remarkable for two early childhood cases of adrenocortical tumours, family B for a high incidence of many characteristic cancers, including a childhood case of choroid plexus tumour. Using direct sequencing, we analysed exons 5-9 of the p53 gene in constitutional DNA of individuals from both families and found two novel germline mutations in exon 5. In family A, we detected a point substitution in codon 138 (GCC to CCC), which resulted in the replacement of the alanine by a proline residue. Family B harboured a single-base pair deletion in codon 178 (CAC to -AC), resulting in a frameshift and premature chain termination. Three out of six tumours examined from both families, a renal cell carcinoma, a rhabdomyosarcoma and a breast cancer, showed loss of heterozygosity and contained only the mutant p53 allele. The remaining three neoplasms, both adrenocortical tumours and the choroid plexus tumour retained heterozygosity. Immunohistochemistry with anti-p53 antibody confirmed accumulation of p53 protein in tumours with loss of heterozygosity, while the remaining tumours were p53 negative. These results support the view that complete loss of activity of the wild-type p53 need not be the initial event in the formation of all tumours in Li-Fraumeni individuals.

    Germ line mutations in the tumor suppressor gene, p53, are known to cause Li-Fraumeni syndrome (LFS) or Li-Fraumeni-like syndrome (LFL). We sought to identify p53 germ line mutations in potential hereditary breast cancer patients without LFS/LFL phenotype, which will help us establish the genetic testing strategy for p53 in Chinese high-risk breast cancer families. We screened all coding exons and intron-exon boundaries of p53 in 240 women with early-onset breast cancer or affected relatives from four breast disease clinical centers in China by utilizing PCR-DHPLC and DNA sequencing analysis. Additionally, three cell lines (H1299, MCF-7, and MDA-MB-231) were transfected with pEGFP-N1-only or pEGFP-N1 vectors expressing either wild-type or two novel identified mutant p53. And then we performed flow cytometry analysis in the transfected cells to determine the status of cell apoptosis, and real-time PCR as well as western blot analysis to ascertain the expression of p53, p21, and p27. Two novel germ line mutations (563T > C and 643_660del18) were detected in two independent families. Neither of them, however, was present in the 768 normal controls. Functional assays revealed that the ability to trigger cell apoptosis and transcriptional activation of target gene under similar expression of p53 were lower in two mutants versus wild-type p53. Deleterious mutations of p53 seemed to be responsible for approximately 1% of non-BRCA1/BRCA2 hereditary breast cancer in Chinese population, and our findings suggested that p53 should be included in genetic testing of Chinese non-LFS/non-LFL high-risk breast cancer families.

    Knockout mice with only one Trp53 allele (+/- genotype) are highly susceptible to radiation-induced cancers, possibly through numerical chromosome changes. Patients with the Li-Fraumeni syndrome, having heterozygous TP53 germline mutations (+/mut genotype), are also susceptible to spontaneous and radiogenic cancers. We have investigated the susceptibility of six Li-Fraumeni syndrome +/mut and six normal fibroblast strains to induced numerical and unstable structural aberrations at six population doublings after exposure to 3 or 6 Gy gamma rays. Four of the irradiated Li-Fraumeni syndrome strains showed small increases in both aberration types, similar to those seen in the normal strains. In two irradiated Li-Fraumeni syndrome strains, there were high levels of induced structural changes, and one of these showed a modest increase in hyperploidy. We suggest that enhanced sensitivity to delayed radiation-induced chromosome changes in Li-Fraumeni syndrome cells requires other genetic alterations in addition to TP53 heterozygosity, apparently in contrast to the situation in Trp53 heterozygous null mice. If such additional alterations occur in vivo in Li-Fraumeni syndrome patients, they may predispose them to radiogenic cancers, mainly through enhanced structural rather than numerical chromosome changes. Our findings raise questions about the validity of quantitative extrapolation of cytogenetic data from Trp53-defective mice to radiogenic cancer risk in humans. PMID:11835679

    Oral squamous cell carcinoma is the most common malignancy of the oral cavity, which is usually preceded by a myriad of oral potentially malignant disorders (OPMDs). In the classification of OPMDs, inherited cancer syndromes (ICSs) were proposed as one of the categories. Inherited cancer syndromes are genetic disorders in which inherited genetic mutation in one or more genes predispose the affected individuals to the development of cancer and may also cause its early onset. Many of these syndromes are caused by mutations in tumor suppressor genes, oncogenes, and genes involved in angiogenesis. General dental practitioners frequently come across OPMDs in their day-to-day practice. It becomes of paramount importance to have knowledge about these rare but prognostically important OPMDs. With this view in mind, in this article, efforts have been made to comprehensively discuss about various ICSs that have higher potential of transformation into oral cancer. The ICSs discussed in this article are xeroderma pigmentosum (XP), ataxia telangiectasia (AT), Bloom syndrome (BS), Fanconi's anemia (FA), and Li-Fraumeni syndrome (LFS), with special emphasis on signs, symptoms, and genetic considerations.

    A critical issue in the design of the ITER Low Field Side (LFS) reflectometer is the transmission line (TL) system. A TL connects each launcher to a diagnostic instrument. Each TL will typically consist of ~42 m of corrugated waveguide and up to 10 miter bends. Important issues for the performance of the TL system are mode conversion and reflections. Minimizing mode conversion and reflections in the waveguide are critical to minimizing standing waves and phase errors in the reflectometer-measured phase. The performance of the corrugated waveguide and miter bends is analyzed and recommendations given.

    In the present investigation, a microorganism hydrolyzing carboxymethylcellulose (CMC) was isolated and identified as Bacillus subtilis strain LFS3 by 16S rDNA sequence analysis. The carboxymethylcellulase (CMCase) enzyme produced by the B. subtilis strain LFS3 was purified by (NH₄)₂SO₄ precipitation, ion exchange and gel filtration chromatography, with an overall recovery of 15 %. Native-PAGE analysis of purified CMCase revealed the molecular weight of enzyme to be about 185 kDa. The activity profile of CMCase enzyme showed the optimum activity at temperature 60 °C and pH 4.0, respectively. The enzyme activity was induced by Na⁺, Mg²⁺, NH₄⁺, and EDTA, whereas strongly inhibited by Hg²⁺ and Fe³⁺. The purified enzyme hydrolyzed CMC, filter paper, and xylan, but not p-nitrophenyl β-D-glucopyranoside and cellulose. Kinetic analysis of purified enzyme showed the K(m) value of 2.2 mg/ml. Thus, acidophilic as well as thermophilic nature makes this cellulase a suitable candidate for current mainstream biomass conversion into fuel and other industrial processes. PMID:22610115

    Onion and garlic are renowned for their roles as functional foods. The health benefits of garlic are attributed to di-2-propenyl thiosulfinate (allicin), a sulfur compound found in disrupted garlic but not found in disrupted onion. Recently, onions have been grown with repressed lachrymatory factor synthase (LFS) activity, which causes these onions to produce increased amounts of di-1-propenyl thiosulfinate, an isomer of allicin. This investigation into the key health attributes of LFS-silenced (tearless) onions demonstrates that they have some attributes more similar to garlic and that this is likely due to the production of novel thiosulfinate or metabolites. The key finding was that collagen-induced in vitro platelet aggregation was significantly reduced by tearless onion extract over normal onion extract. Thiosulfinate or derived compounds were shown not to be responsible for the observed changes in the inflammatory response of AGS (stomach adenocarcinoma) cells to tumor necrosis factor alpha (TNFα) when pretreated with model onion juices. A preliminary rat feeding trial indicated that the tearless onions may also play a key role in reducing weight gain. PMID:24147811

    The study of rare families in which a variety of cancers occur, usually at an early age and with patterns consistent with a common hereditary mechanism, has contributed much to our understanding of the process of carcinogenesis. So far, genes identified as having a role in cancer predisposition in these families have also been important in the histogenesis of sporadic cancers. In the two most clearly defined cancer family syndromes, the Li-Fraumeni syndrome and Lynch syndrome II, the genes involved predispose to diverse but specific constellations of cancers. Genes associated with site-specific familial cancer clusters may also give rise to increased susceptibility to other cancers, and site-specific clusters may represent one end of a spectrum. A consistent feature of familial cancer syndromes is the variable expression within and between families. A challenge for the future will be to determine other factors which may interact with the principal genes involved, giving rise to this variability. PMID:7987644

    The clinical diagnosis of Lujan-Fryns syndrome (LFS) comprises X-linked intellectual disability (XLID) with marfanoid habitus, distinct combination of minor facial anomalies and nasal speech. However the definition of syndrome was significantly broadened since the original report and implies ID with marfanoid habitus. Mutations of three genes (MED12, UPF3B, and ZDHHC9) have been reported in "broadly defined" LFS. We examined these genes in 28 individuals with a tentative clinical diagnosis of LFS but we did not identify any causative mutation. By molecular karyotyping we detected other disorders, i.e., Phelan-McDermid syndrome and 16p11.2 microduplication, each in one patient. One affected individual was carrier of a different recurrent duplication on 16p11.2 that has been reported several times to the DECIPHER and ISCA databases in individuals with autism, intellectual disability (ID), and developmental delay. It may represent a new duplication syndrome. We also identified previously unreported de novo duplication on chromosome 12p13.31 which we considered to be disease-causing. X-exome sequencing of four individuals revealed private or non-recurrent mutations in NKAP and LAS1L in one patient each. While LFS is defined as a form of XLID, there seem to be various conditions that have rather similar phenotypes. Therefore, the combination of ID and marfanoid habitus in a male patient is not sufficient for the diagnosis of LFS. We suggest that the diagnosis of LFS in patients with ID and marfanoid habitus should be made only in presence of specific facial features, nasal speech and obvious X-linked segregation of the disorder or an unambiguously pathogenic mutation in the MED12.

    SUMMARY In vitro modeling of human disease has recently become feasible with induced pluripotent stem cell (iPSC) technology. Here, we established patient-derived iPSCs from a Li-Fraumeni Syndrome (LFS) family and investigated the role of mutant p53 in the development of osteosarcoma (OS). LFS iPSC-derived osteoblasts (OBs) recapitulated OS features including defective osteoblastic differentiation as well as tumorigenic ability. Systematic analyses revealed that the expression of genes enriched in LFS-derived OBs strongly correlated with decreased time to tumor recurrence and poor patient survival. Furthermore, LFS OBs exhibited impaired upregulation of the imprinted gene H19 during osteogenesis. Restoration of H19 expression in LFS OBs facilitated osteoblastic differentiation and repressed tumorigenic potential. By integrating human imprinted gene network (IGN) into functional genomic analyses, we found that H19 mediates suppression of LFS-associated OS through the IGN component DECORIN (DCN). In summary, these findings demonstrate the feasibility of studying inherited human cancer syndromes with iPSCs. PMID:25860607

    PubMed

    2015-06-01

    A hereditary cancer syndrome is a genetic predisposition to certain types of cancer, often with onset at an early age, caused by inherited mutations in one or more genes. Cases of cancer commonly encountered by obstetrician-gynecologists or other obstetric-gynecologic providers--such as breast cancer, ovarian cancer, and endometrial cancer--are features of specific hereditary cancer syndromes. The most common hereditary cancer syndromes related to gynecologic cancer include hereditary breast and ovarian cancer syndrome, Lynch syndrome, Li-Fraumeni syndrome, Cowden syndrome, and Peutz-Jeghers syndrome. A hereditary cancer risk assessment is the key to identifying patients and families who may be at increased risk of developing certain types of cancer. Screening should include, at minimum, a personal cancer history and a first- and second-degree relative cancer history that includes a description of the type of primary cancer, the age of onset, and the lineage (paternal versus maternal) of the family member. In addition, a patient's ethnic background can influence her genetic risk. If a hereditary cancer risk assessment suggests an increased risk of a hereditary cancer syndrome, referral to a specialist in cancer genetics or a health care provider with expertise in genetics is recommended for expanded gathering of family history information, risk assessment, education, and counseling, which may lead to genetic testing.

    Cardiac angiosarcoma (CAS) is a rare malignant tumour whose genetic basis is unknown. Here we show, by whole-exome sequencing of a TP53-negative Li–Fraumeni-like (LFL) family including CAS cases, that a missense variant (p.R117C) in POT1 (protection of telomeres 1) gene is responsible for CAS. The same gene alteration is found in two other LFL families with CAS, supporting the causal effect of the identified mutation. We extend the analysis to TP53-negative LFL families with no CAS and find the same mutation in a breast AS family. The mutation is recently found once in 121,324 studied alleles in ExAC server but it is not described in any other database or found in 1,520 Spanish controls. In silico structural analysis suggests how the mutation disrupts POT1 structure. Functional and in vitro studies demonstrate that carriers of the mutation show reduced telomere-bound POT1 levels, abnormally long telomeres and increased telomere fragility. PMID:26403419

    Purpose: Adrenocortical carcinoma (ACC) is a hallmark cancer in families with Li Fraumeni syndrome (LFS) caused by mutations in the TP53 gene. The prevalence of germline TP53 mutations in children diagnosed with ACC ranges from 50–97%. Although existing criteria advocate for TP53 testing in all patients with ACC regardless of age at diagnosis, the overall prevalence of germline mutations in patients diagnosed with ACC has not been well studied. Patients and Methods: A total of 114 patients with confirmed ACC evaluated in the University of Michigan Endocrine Oncology Clinic were prospectively offered genetic counseling and TP53 genetic testing, regardless of age at diagnosis or family history. Ninety-four of the 114 patients met with a genetic counselor (82.5%), with 53 of 94 (56.4%) completing TP53 testing; 9.6% (nine of 94) declined testing. The remainder (32 of 94; 34%) expressed interest in testing but did not pursue it for various reasons. Results: Four of 53 patients in this prospective, unselected series were found to have a TP53 mutation (7.5%). The prevalence of mutations in those diagnosed over age 18 was 5.8% (three of 52). There were insufficient data to estimate the prevalence in those diagnosed under age 18. None of these patients met clinical diagnostic criteria for classic LFS. Three of the families met criteria for Li Fraumeni-like syndrome; one patient met no existing clinical criteria for LFS or Li Fraumeni-like syndrome. Three of the four patients with mutations were diagnosed with ACC after age 45. Conclusions: Genetic counseling and germline testing for TP53 should be offered to all patients with ACC.

    Purpose Established guidelines recommend evaluation for hereditary cancer syndromes in patients younger than 50 years diagnosed with colorectal cancer (CRC). This group has been well described in the literature; however, patients diagnosed as adolescents and young adults are not well represented in CRC studies. Here, we define the clinical profile, including the extent of hereditary cancer syndromes and family history of cancer, in patients diagnosed with CRC at age 35 or younger. Patients and Methods We reviewed patients who underwent genetic counseling at our institution during 5 years (2009 to 2013). Data were collected regarding demographics, clinicopathologic information, tumor and genetic testing, and family history. Patients with an identified hereditary cancer syndrome were compared with those without a syndrome. Results Of the 193 patients with evaluable data, 35% had an identifiable hereditary cancer syndrome, including 23 with Lynch syndrome, 22 with mutation-negative Lynch syndrome, 16 with familial adenomatous polyposis, two with constitutional mismatch repair deficiency, two with biallelic MUTYH mutations, and one with Li-Fraumeni syndrome. Patients without a hereditary syndrome more frequently presented with metastatic disease, whereas patients with a syndrome were more likely to present at earlier stages and to have a family history of cancer. Nevertheless, a substantial proportion of the hereditary syndromes (19%) were diagnosed in individuals with no family history of the disease. Conclusion We conclude that patients diagnosed with CRC at age 35 years or younger should receive genetic counseling regardless of their family history and phenotype. PMID:26195711

    The predisposition to malignancy that is dominantly inherited in Li-Fraumeni syndrome is associated with germline mutations of the tumour suppressor gene p53. Although second malignant neoplasms have been described in children with p53 mutations, the synchronous occurrence of two embryologically different tumours in these children has not been reported. A 20 month old girl with failure to thrive and congenital heart defects was found to have unilateral adrenal masses which, at surgical removal, proved to be an adrenocortical carcinoma and a ganglioneuroblastoma. Further investigation showed a germline p53 mutation and Turner syndrome. It remains to be determined what effect the 45,X chromosomal complement may have on the expression of neoplasms seen in patients with p53 germline mutations. Images PMID:9598730

    Lavender Foal Syndrome (LFS) is a lethal inherited disease of horses with a suspected autosomal recessive mode of inheritance. LFS has been primarily diagnosed in a subgroup of the Arabian breed, the Egyptian Arabian horse. The condition is characterized by multiple neurological abnormalities and a dilute coat color. Candidate genes based on comparative phenotypes in mice and humans include the ras-associated protein RAB27a (RAB27A) and myosin Va (MYO5A). Here we report mapping of the locus responsible for LFS using a small set of 36 horses segregating for LFS. These horses were genotyped using a newly available single nucleotide polymorphism (SNP) chip containing 56,402 discriminatory elements. The whole genome scan identified an associated region containing these two functional candidate genes. Exon sequencing of the MYO5A gene from an affected foal revealed a single base deletion in exon 30 that changes the reading frame and introduces a premature stop codon. A PCR–based Restriction Fragment Length Polymorphism (PCR–RFLP) assay was designed and used to investigate the frequency of the mutant gene. All affected horses tested were homozygous for this mutation. Heterozygous carriers were detected in high frequency in families segregating for this trait, and the frequency of carriers in unrelated Egyptian Arabians was 10.3%. The mapping and discovery of the LFS mutation represents the first successful use of whole-genome SNP scanning in the horse for any trait. The RFLP assay can be used to assist breeders in avoiding carrier-to-carrier matings and thus in preventing the birth of affected foals. PMID:20419149

    Li-Fraumeni syndrome (LFS) is a rare, autosomal dominant, hereditary cancer predisposition disorder. In Brazil, the p.R337H TP53 founder mutation causes the variant form of LFS, Li-Fraumeni-like syndrome. The occurrence of cancer and age of disease onset are known to vary, even in patients carrying the same mutation, and several mechanisms such as genetic and epigenetic alterations may be involved in this variability. However, the extent of involvement of such events has not been clarified. It is well established that p53 regulates several pathways, including the thymine DNA glycosylase (TDG) pathway, which regulates the DNA methylation of several genes. This study aimed to identify the DNA methylation pattern of genes potentially related to the TDG pathway (CDKN2A, FOXA1, HOXD8, OCT4, SOX2, and SOX17) in 30 patients with germline TP53mutations, 10 patients with wild-type TP53, and 10 healthy individuals. We also evaluated TDG expression in patients with adrenocortical tumors (ADR) with and without the p.R337H TP53 mutation. Gene methylation patterns of peripheral blood DNA samples assessed by pyrosequencing revealed no significant differences between the three groups. However, increased TDG expression was observed by quantitative reverse transcription PCR in p.R337H carriers with ADR. Considering the rarity of this phenotype and the relevance of these findings, further studies using a larger sample set are necessary to confirm our results. PMID:25945745

    The etiologic contribution of germline genetic variation to sporadic osteosarcoma is not well understood. Osteosarcoma is a sentinel cancer of Li-Fraumeni syndrome (LFS), in which approximately 70% of families meeting the classic criteria have germline TP53 mutations. We sequenced TP53 exons in 765 osteosarcoma cases. Data were analyzed with χ2 tests, logistic regression, and Cox proportional hazards regression models. We observed a high frequency of young osteosarcoma cases (age <30 years) carrying a known LFS- or likely LFS-associated mutation (3.8%) or rare exonic variant (5.7%) with an overall frequency of 9.5%, compared with none in case patients age 30 years and older (P < .001). This high TP53 mutation prevalence in young osteosarcoma cases is statistically significantly greater than the previously reported prevalence of 3% (P = .0024). We identified a novel association between a TP53 rare variant and metastasis at diagnosis of osteosarcoma (rs1800372, odds ratio = 4.27, 95% confidence interval = 1.2 to 15.5, P = .026). Genetic susceptibility to young onset osteosarcoma is distinct from older adult onset osteosarcoma, with a high frequency of LFS-associated and rare exonic TP53 variants. PMID:25896519

    Netherton syndrome (NS) is a rare autosomal recessive disorder which is caused by mutations in the SPINK5 gene encoding the serine-protease inhibitor LEKTI. Characteristic symptoms of NS include erythroderma with diffuse desquamation, hair abnormalities and atopic manifestations. Here, we report two Japanese patients with NS, one of whom had a novel mutation in the SPINK5 gene which leads to p.C367Lfs*3. The upregulation of interleukin-33 (IL-33) was evident in basal and thickened lower spinous layers of the epidermis in those cases. This suggests that IL-33 may be involved in the pathophysiology of NS as well as in atopic dermatitis. PMID:24506793

    Adrenocortical carcinoma (ACC) affects children and adults. Roughly 50% of very early onset ACCs occur in children with germline TP53 mutations. Several recent studies have extended our understanding in basic, clinical, and translational genetics with regard to TP53 germline predisposition in ACC patients. The recent description of the molecular landscape of pediatric ACCs provided insight into differences of tumors arising in patients with and without TP53 germline mutation. Another recent important finding is that not all TP53 mutations are equal in their tumor suppressing potential. It has now been shown that family histories as well as molecular characteristics of preserved TP53 functions vary greatly between mutations. It also has become clear that adult patients with ACC often harbor germline mutations causing hereditary syndromes, including Li-Fraumeni syndrome (LFS), Lynch syndrome, and multiple endocrine neoplasia type 1 (MEN1).

    Germline TP53 mutations predispose individuals to multiple cancers and are associated with Li-Fraumeni/Li-Fraumeni-Like Syndromes (LFS/LFL). The founder mutation TP53 p.R337H is detected in 0.3% of the general population in southern Brazil. This mutation is associated with an increased risk of childhood adrenal cortical carcinoma (ACC) but is also common in Brazilian LFS/LFL families. Breast Cancer (BC) is one of the most common cancers diagnosed in TP53 mutation carriers. We have assessed the prevalence of p.R337H in two groups: (1) 59 BC affected women with a familial history (FH) suggestive of hereditary cancer syndrome but no LFS/LFL features; (2) 815 BC affected women unselected for cancer FH, diagnosed with BC at or before age 45 or at age 55 or older. Among group 1 and group 2 patients, 2/59 (3.4%, CI95%: 0.4%–11.7%) and 70/815 (8.6%, CI95%: 6.8%–10.7%), respectively, were p.R337H carriers in the germline. The prevalence of p.R337H was higher in women diagnosed with BC at or before age 45 (12.1%, CI95%: 9.1%–15.8%) than at age 55 or older (5.1%, CI95%: 3.2%–7.7%), p<0.001). The Brazilian founder p.R337H haplotype was detected in all carriers analysed. These results suggest that inheritance of p.R337H may significantly contribute to the high incidence of BC in Brazil, in addition to its recently demonstrated impact on the risk of childhood ACC.

    Rare germline mutations in TP53 (17p13.1) cause a highly penetrant predisposition to a specific spectrum of early cancers, defining the Li-Fraumeni Syndrome (LFS). A germline mutation at codon 337 (p.Arg337His, c1010G>A) is found in about 0.3% of the population of Southern Brazil. This mutation is associated with partially penetrant LFS traits and is found in the germline of patients with early cancers of the LFS spectrum unselected for familial history. To characterize the extended haplotypes carrying the mutation, we have genotyped 9 short tandem repeats on chromosome 17p in 12 trios of Brazilian p.Arg337His carriers. Results confirm that all share a common ancestor haplotype of Caucasian/Portuguese-Iberic origin, distant in about 72–84 generations (2000 years assuming a 25 years intergenerational distance) and thus pre-dating European migration to Brazil. So far, the founder p.Arg337His haplotype has not been detected outside Brazil, with the exception of two residents of Portugal, one of them of Brazilian origin. On the other hand, increased meiotic recombination in p.Arg337His carriers may account for higher than expected haplotype diversity. Further studies comparing haplotypes in populations of Brazil and of other areas of Portuguese migration are needed to understand the historical context of this mutation in Brazil. PMID:26618902

    Germline mutations in the TP53 gene are associated with Li-Fraumeni and Li-Fraumeni-Like Syndromes, characterized by increased predisposition to early-onset cancers. In Brazil, the prevalence of the TP53-p.R337H germline mutation is exceedingly high in the general population and in cancer-affected patients, probably as result of a founder effect. Several genotyping methods are used for the molecular diagnosis of LFS/LFL, however Sanger sequencing is still considered the gold standard. We compared performance, cost and turnaround time of Sanger sequencing, PCR-RFLP, TaqMan-PCR and HRM in the p.R337H genotyping. The performance was determined by analysis of 95 genomic DNA samples and results were 100% concordant for all methods. Sequencing was the most expensive method followed by TaqMan-PCR, PCR-RFLP and HRM. The overall cost of HRM increased with the prevalence of positive samples, since confirmatory sequencing must be performed when a sample shows an abnormal melting profile, but remained lower than all other methods when the mutation prevalence was less than 2.5%. Sequencing had the highest throughput and the longest turnaround time, while TaqMan-PCR showed the lowest turnaround and hands-on times. All methodologies studied are suitable for the detection of p.R337H and the choice will depend on the application and clinical scenario. PMID:27275664

    Ionizing radiation induces DNA Double-Strand Breaks (DSBs), which activate the ATM/CHEK2/p53 pathway leading to cell cycle arrest and apoptosis through transcription of genes including CDKN1A (p21) and BBC3 (PUMA). This pathway prevents genomic instability and tumorigenesis as demonstrated in heritable syndromes [e.g., Ataxia Telangiectasia (AT); Li-Fraumeni syndrome (LFS)]. Here, a simple assay based on gene expression in peripheral blood to measure accurately ATM/CHEK2/p53 pathway activity is described. The expression of p21, Puma and Sesn2 was determined in blood from mice with different gene copy numbers of Atm, Trp53 (p53), Chek2 or Arf and in human blood and mitogen stimulated T-lymphocyte (MSTL) cultures from AT, AT carriers, LFS patients and controls, both before and after ex vivo ionizing irradiation. Mouse Atm/Chek2/p53 activity was highly dependent on the copy number of each gene except Arf. In human MSTL, an AT case, AT carriers and LFS patients showed responses distinct from healthy donors. The relationship between gene copy number and transcriptional induction upon radiation was linear for p21 and Puma and correlated well with cancer incidence in p53 variant mice. This reliable blood test provides an assay to determine ATM/CHEK2/p53 pathway activity and demonstrates the feasibility of assessing the activity of this essential cancer protection pathway in simple assays. These findings may have implications for the individualized prediction of cancer susceptibility. PMID:21389785

    Pseudoaminopterin syndrome or aminopterin syndrome-like sine aminopterin (ASSA syndrome--OMIM 600325] is a rare autosomal recessive syndrome defined by characteristic dysmorphic features, skeletal defects, limb anomalies, cryptorchidism, and growth retardation. The syndrome owes its name to the fact that patients resemble the children exposed to aminopterin or to methotrexate, two dihydrofolate reductase inhibitors used for chemotherapy, or as an abortificient in early pregnancy. Ten patients have been described with pseudoaminopterin syndrome. Their phenotype is variable, and differs from the phenotype resulting from folic acid deprivation, leading to the notion that the pathogenesis may be more complex than simple vitamin deficiency. We report on an Algerian patient with pseudoaminopterin syndrome, review the previously reported cases and confirm that pseudoaminopterin syndrome does not result from a detectable contiguous gene imbalance as high resolution CGH array was normal in this child.

    2008-04-01

    Birt-Hogg-Dubé syndrome (BHDS) is an autosomal dominant genodermatosis characterized by cutaneous hair follicle tumors (fibrofolliculoma or trichodiscoma), pulmonary cysts, and increased risk of renal neoplasia. The genetic alteration for BHDS has been mapped to chromosome 17p12q11, and the gene in this region has been cloned and believed to be responsible for the BHDS. Mutations in the BHD gene (also known as FLCN) have been described in the patients with BHDS. We present a case of a 30-yr-old Korean woman with multiple mildly pruritic papules on her face and neck area. The patient had several firm, flesh-colored, dome-shaped, papular lesions measuring between 2 to 5 mm. Except for a history of pneumothorax her medical records were not remarkable. Mutation analysis of the BHD gene was performed, and a novel deletion mutation (p.F519LfsX17 [c.1557delT]) causing truncation of the gene product, folliculin, was found in the exon 14. The actual incidence of BHDS is unknown, but it is most likely underdiagnosed. So it is imperative that doctors recognize the skin lesions of BHDS and institute proper screening to detect other manifestations of the disease. Here, we report a case of BHDS with a novel mutation, which is the first report in Korea. PMID:18437022

    2015-10-01

    Kounis syndrome is characterised by a group of symptoms that manifest as unstable vasospastic or non-vasospastic angina secondary to a hypersensitivity reaction. It was first described by Kounis and Zavras in 1991 as the concurrence of an allergic response with an anaphylactoid or anaphylactic reaction and coronary artery spasm or even myocardial infarction. Since then, this condition has evolved to include a number of mast cell activation disorders associated with acute coronary syndrome. There are many triggering factors, including reactions to multiple medications, exposure to radiological contrast media, poison ivy, bee stings, shellfish and coronary stents. In addition to coronary arterial involvement, Kounis syndrome comprises other arterial systems with similar physiologies, such as mesenteric and cerebral circulation resulting in ischaemia/infarction of the vital organs. The incidence of this condition is difficult to establish owing to the number of potential instigating factors and its relatively infrequent documentation in the literature.We report the case of an HIV-negative 39-year-old man with no coronary risk factors or family history of premature coronary artery disease, who developed Kounis syndrome after the administration of fluoroquinolone for dysuria. However, to the best of our knowledge,no data on the incidence and prevalence of Kounis syndrome in South Africa have ever been reported in the literature. The recent understanding of Kounis syndrome has led to the condition being classified into three syndrome variants. PMID:26636160

    PubMed

    Klar, Nitasha; Cohen, Bernard; Lin, Doris D M

    2016-01-01

    Neurocutaneous syndromes (or phakomatoses) are a diverse group of congenital disorders that encompass abnormalities of neuroectodermal and, sometimes, mesodermal development, hence commonly involving the skin, eye, and central nervous system. These are often inherited conditions and typically present in early childhood or adolescence. Some of the abnormalities and clinical symptoms may, however, be progressive, and there is an increased risk of neoplastic formation in many of the syndromes. As a group, neurocutaneous syndromes are characterized by distinctive cutaneous stigmata and neurologic symptomology, the latter often representing the most devastating and debilitating features of these diseases. Many of these syndromes are markedly heterogeneous in nature as they affect many organ systems. Given the incurable nature of these conditions and the broad spectrum of pathologies they comprise, treatments vary on a case-by-case basis and tend to be palliative rather than curative. With the advances in molecular genetics, however, greater understanding of biologic functions of the gene products and the correlative phenotypic expression is being attained, and this knowledge may guide future therapeutic developments. This chapter focuses on the cutaneous and neurologic pathology with emphasis on neuroimaging of selective neurocutaneous syndromes, including tuberous sclerosis, Sturge-Weber syndrome, Klippel-Trenaunay syndrome, ataxia-telangiectasia, and incontinentia pigmenti.

    2014-01-01

    Background Recent genomic sequencing efforts have identified a number of recurrent mutations in myelodysplastic syndromes (MDS) that may contribute to disease progression and overall survival, including mutations in isocitrate dehydrogenases 1 and 2 (IDH1 and IDH2). Methods Pretreatment bone marrow (BM) samples were acquired from mononuclear cells in 146 adult patients with de novo MDS from January 2006 to June 2013. Polymerase chain reaction (PCR) and direct sequencing were performed on exon 4 of IDH1/2 genes and mutation status was correlated with overall survival (OS) and leukemia-free survival (LFS). We then performed a meta-analysis combining previously published and current studies to explore the effect of IDH mutations on OS and LFS in MDS. Results In our study, somatic mutations of either IDH gene were discovered in 11 MDS patients (7.53%) and were significantly correlated with poorer OS (P = 0.007). IDH mutations were specifically associated with a poorer OS in the intermediate-1 risk group by the International Prognostic Scoring System (IPSS) (P = 0.039). In addition, we discovered decitabine achieved a better therapeutic effect compared to other treatments in IDH mutation-positive patients (P = 0.023). We identified six previous studies of IDH mutations in MDS. A meta-analysis of these studies included 111 MDS patients IDH mutations and 1671 MDS patients with wild-type IDH1/2. The hazard ratios (HRs) of OS and LFS for patients with IDH mutations were 1.62 (95% CI, 1.27–2.09) and 2.21 (95% CI, 1.48–3.30), respectively. Conclusion The results from our study and the meta-analysis provide firm evidence that IDH mutations are significantly associated with poorer clinical outcomes in MDS. Identification of IDH mutations may be pivotal for better risk stratification in MDS patients and improving IPSS score. Additionally, hypomethylating agents may be an effective treatment option for MDS patients with IDH mutations. PMID:24936872

Organ damage, eosinophilia and skin rash are typical at presentation. Corticotherapy is often necessary in severe cases. In this report we describe a case of 56-year old female with fever, elevated liver tests and skin rash. DRESS syndrome was diagnosed and allopurinol was indentified as a causative drug. Due to possible fatal outcome, DRESS syndrome should be considered in a differential diagnosis of all patients presenting with similar signs and symptoms. PMID:27250614

    Neoplasms can produce a variety of remote effects on the host; these are referred to as paraneoplastic syndromes. The syndromes may affect any of the systems of the body, may precede or follow the diagnosis of the underlying neoplasm, and may or may not parallel the course of the neoplasm in severity. The diagnosis of and therapy for these syndromes can be challenging to a physician, but successful therapy may bring about worthwhile relief for the patient. In addition, the syndromes and the substances that cause them are sometimes useful in diagnosing and in following the course of certain neoplasms. Perhaps of greater importance, study of these remote effects of neoplasia may shed light on the nature of the neoplastic process itself. PMID:6990627

    The DIDMOAD or so called Wolfram syndrome is a hereditary disease with autosomal-recessive transmission showing 4 main features: diabetes mellitus, diabetes insipidus, nervus opticus atrophia and deafness. Beside this it shows multiple organ involvement. Our 38-year old male patient, showing all above mentioned features except deafness had urinary tract involvement and neurological symptoms. EEG, cerebral MRI, tests with evoked potentials and HLA-typing were performed to discuss the aetiopathogenetic background in our patient. Almost all symptoms of the Wolfram syndrome can be mixed up with complications of diabetes mellitus, which is usually the first symptom of the Wolfram syndrome. Because of this, wrong diagnosis is not rare. Hence in differential diagnosis in any diabetes mellitus type I patient, the possibility of the Wolfram syndrome should be discussed. PMID:8023526

    Hepatopulmonary syndrome is characterized by the presence of liver disease, pulmonary vascular dilatations, and arterial hypoxemia. It is usually associated with cirrhosis of any origin, but has been described in other liver diseases, both acute and chronic, and not always associated with portal hypertension. The gold standard method to detect pulmonary vascular dilations is contrast enhancement echocardiography with saline and is essential for the diagnosis of hepatopulmonary syndrome. These dilatations reflect changes in the pulmonary microvasculature (vasodilatation, intravascular monocyte accumulation, and angiogenesis) and induce a ventilation/perfusion mismatch, or even true intrapulmonary shunts, which eventually trigger hypoxemia. This syndrome worsens patients' prognosis and impairs their quality of life and may lead to the need for liver transplantation, which is the only effective and definitive treatment. In this article, we review the etiological, pathophysiological, clinical and therapeutic features of this syndrome. PMID:25840463

    Alagille syndrome (OMIM 118450) is an autosomal dominant disorder associated with abnormalities of the liver, heart, eye, skeleton, and a characteristic facial appearance. Also referred to as the Alagille-Watson syndrome, syndromic bile duct paucity, and arteriohepatic dysplasia, it is a significant cause of neonatal jaundice and cholestasis in older children. In the fully expressed syndrome, affected subjects have intrahepatic bile duct paucity and cholestasis, in conjunction with cardiac malformations (most frequently peripheral pulmonary stenosis), ophthalmological abnormalities (typically of the anterior chamber with posterior embryotoxon being the most common), skeletal anomalies (most commonly butterfly vertebrae), and characteristic facial appearance. Inheritance is autosomal dominant, but expressivity is highly variable. Sibs and parents of probands are often found to have mild expression of the presumptive disease gene, with abnormalities of only one or two systems. The frequency of new mutations appears relatively high, estimated at between 15 and 50%. The disease gene has been mapped to chromosome 20 band p12 based on multiple patients described with cytogenetic or molecular rearrangements of this region. However, the frequency of detectable deletions of 20p12 is low (less than 7%). Progress has been made in the molecular definition of an Alagille syndrome critical region within the short arm of chromosome 20. We will review the clinical, genetic, cytogenetic, and molecular findings in this syndrome. Images PMID:9039994

    The antiphospholipid syndrome causes venous, arterial, and small-vessel thrombosis; pregnancy loss; and preterm delivery for patients with severe pre-eclampsia or placental insufficiency. Other clinical manifestations are cardiac valvular disease, renal thrombotic microangiopathy, thrombocytopenia, haemolytic anaemia, and cognitive impairment. Antiphospholipid antibodies promote activation of endothelial cells, monocytes, and platelets; and overproduction of tissue factor and thromboxane A2. Complement activation might have a central pathogenetic role. Of the different antiphospholipid antibodies, lupus anticoagulant is the strongest predictor of features related to antiphospholipid syndrome. Therapy of thrombosis is based on long-term oral anticoagulation and patients with arterial events should be treated aggressively. Primary thromboprophylaxis is recommended in patients with systemic lupus erythematosus and probably in purely obstetric antiphospholipid syndrome. Obstetric care is based on combined medical-obstetric high-risk management and treatment with aspirin and heparin. Hydroxychloroquine is a potential additional treatment for this syndrome. Possible future therapies for non-pregnant patients with antiphospholipid syndrome are statins, rituximab, and new anticoagulant drugs. PMID:20822807

    The classic electrocardiogram in Wolff-Parkinson-White (WPW) syndrome is characterized by a short PR interval and prolonged QRS duration in the presence of sinus rhythm with initial slurring. The clinical syndrome associated with above electrocardiogram finding and the history of paroxysmal supraventricular tachycardia is referred to as Wolff-Parkinson-White syndrome. Various eponyms describing accessory or anomalous conduction pathways in addition to the normal pathway are collectively referred to as preexcitation syndromes. The latter form and associated eponyms are frequently used in literature despite controversy and disagreements over their actual anatomical existence and electrophysiological significance. This communication highlights inherent deficiencies in the knowledge that has existed since the use of such eponyms began. With the advent of curative ablation, initially surgical, and then catheter based, the knowledge gaps have been mostly filled with better delineation of the anatomic and electrophysiological properties of anomalous atrioventricular pathways. It seems reasonable, therefore, to revisit the clinical and electrophysiologic role of preexcitation syndromes in current practice. PMID:26897561

    Lemierre's syndrome is a condition characterized by thrombophlebitis of the internal jugular vein and bacteremia caused by primarily anaerobic organisms, following a recent oropharyngeal infection. This has been an uncommon illness in the era of antibiotic therapy, though it has been reported with increasing frequency in the past 15 years. Lemierre's syndrome should be suspected in young healthy patients with prolonged symptoms of pharyngitis followed by symptoms of septicemia or pneumonia, or an atypical lateral neck pain. Diagnosis is often confirmed by identification of thrombophlebitis of the internal jugular vein and growth of anaerobic bacteria on blood culture. Treatment involves prolonged antibiotic therapy occasionally combined with anticoagulation. We review the literature and a case of a child with Lemierre's syndrome. PMID:24152679

    1989-01-01

    The compartment syndrome is defined as a condition in which high pressure within a closed fascial space (muscle compartment) reduces capillary blood perfusion below the level necessary for tissue viability'. This condition occurs in acute and chronic (exertional) forms, and may be secondary to a variety of causes. The end-result of an extended period of elevated intramuscular pressure may be the development of irreversible tissue injury and Volkmann's contracture. The goal of treatment of the compartment syndrome is the reduction of intracompartmental pressure thus facilitating reperfusion of ischaemic tissue and this goal may be achieved by decompressive fasciotomy. Controversy exists regarding the critical pressure-time thresholds for surgical decompression and the optimal diagnostic methods of measuring intracompartmental pressures. This paper will update and review some current knowledge regarding the pathophysiology, aetiology, diagnosis, and treatment of the acute compartment syndrome.

    The Kallmann syndrome is a very rare congenital association of gonadotropin-releasing hormone deficiency and hyposmia or anosmia. Clinically it is characterized by low serum concentrations of testosterone and inadequate low levels of luteinizing hormone and follicle-stimulating hormone as well as incomplete sexual maturation, lack of secondary sexual features (facial and body hair growth, deepening of the voice), micropenis and sometimes even cryptorchidism. The reduced or absent sense of smell is typical for the Kallmann syndrome and distinguishes this syndrome from other causes of hypogonadotropic hypogonadism. Additional findings may include synkinesia, hearing loss, unilateral renal aplasia, brachy- or syndactyly, agenesis of corpus callosum, cleft palate and dental agenesis. A 19-year-old man presented to our male infertility clinic with delayed sexual maturation, eunuchoid habitus, micropenis, cryptorchidism, erectile dysfunction and absence of ejaculation, anemia and osteoporosis as well as low serum concentrations of luteinizing hormone, follicle-stimulating hormone and testosterone in combination with hyposmia.

    1995-09-01

    Palmoplantar pustulosis and severe acne are sometimes associated with peculiar aseptic skeletal conditions, but such skeletal lesions can be found without skin lesions. The term SAPHO syndrome has been coined for this cluster of manifestations. (The acronym SAPHO refers to synovitis, acne, palmoplantar pustulosis, hyperostosis, and osteitis.) The most common site of the disease is the upper anterior chest wall, characterized by predominantly osteosclerotic lesions, hyperostosis, and arthritis of the adjacent joints. Osteosclerosis of the vertebral bodies, hyperostosis, and erosions of the vertebral plates can be encountered. Unilateral sacroiliitis is frequently observed. Long bone involvement consists of osteosclerosis or osteolysis with periosteal new bone formation. Peripheral arthritis can be present but is rarely associated with joint destruction. The pathogenesis of this syndrome remains unknown, but a link with seronegative spondyloarthropathies is probable. Radiologists should be aware of this unusual syndrome to avoid misdiagnosis (eg, tumor, infection), unnecessary surgery, and antibiotic therapy. PMID:7501856

  2. Flammer syndrome

    PubMed Central

    2014-01-01

    The new term Flammer syndrome describes a phenotype characterized by the presence of primary vascular dysregulation together with a cluster of symptoms and signs that may occur in healthy people as well as people with disease. Typically, the blood vessels of the subjects with Flammer syndrome react differently to a number of stimuli, such as cold and physical or emotional stress. Nearly all organs, particularly the eye, can be involved. Although the syndrome has some advantages, such as protection against the development of atherosclerosis, Flammer syndrome also contributes to certain diseases, such as normal tension glaucoma. The syndrome occurs more often in women than in men, in slender people than in obese subjects, in people with indoor rather than outdoor jobs, and in academics than in blue collar workers. Affected subjects tend to have cold extremities, low blood pressure, prolonged sleep onset time, shifted circadian rhythm, reduced feeling of thirst, altered drug sensitivity, and increased general sensitivity, including pain sensitivity. The plasma level of endothelin-1 is slightly increased, and the gene expression in lymphocytes is changed. In the eye, the retinal vessels are stiffer and their spatial variability larger; the autoregulation of ocular blood flow is decreased. Glaucoma patients with Flammer syndrome have an increased frequency of the following: optic disc hemorrhages, activated retinal astrocytes, elevated retinal venous pressure, optic nerve compartmentalization, fluctuating diffuse visual field defects, and elevated oxidative stress. Further research should lead to a more concise definition, a precise diagnosis, and tools for recognizing people at risk. This may ultimately lead to more efficient and more personalized treatment.

    Congenital heart disease with left-to-right shunt can induce proliferation, vasoconstriction and thrombosis in the pulmonary vascular bed. Eventually, the patient may develop Eisenmenger syndrome defined as pulmonary arterial hypertension caused by high pulmonary vascular resistance with right-to-left shunt and cyanosis. Patients with Eisenmenger syndrome suffer a high risk of complications in connection with acute medical conditions, extra-cardiac surgery and pregnancy. This article describes the precautions that should be taken to reduce morbidity and mortality in these patients. PMID:19416617

    Despite being known more than 60 years, refeeding syndrome (RS) still bears many uncertainties. For example, its definition is not clear and definite, and the attitude to it varies from the complete neglect to over-prevention.The term "refeeding syndrome" refers to electrolyte and metabolic changes occurring in malnourished patients after the readministration of nutrition. These changes concern especially to phosphates and ions. Potassium, magnesium, naturism and fluids balance are involved. The changes lead to cell energetic metabolism and electric potential disturbances, with related clinical symptoms.Fully developed refeeding syndrome is quite rare; nevertheless it can be fatal for the patient. However, even its development can lead to many complications increasing the patient's morbidity and the length of stay in the hospital. Yet the refeeding syndrome is more or less predictable and if kept in mind also preventable.The aim of this article is to get the reader to know more about this metabolic phenomenon and possible attitudes towards it.

    The SAPHO syndrome, an acronym for synovitis, acne, pustulosis, hyperostosis and osteitis, is a rare disease which affects bones, joints and the skin. The main osteoarticular features are hyperostosis and osteitis. Osteoarticular symptoms predominantly occur on the anterior chest wall but the spine and the peripheral skeleton can also be involved. The most important skin affections are palmoplantar pustulosis and severe acne. The etiology of this syndrome remains unclear but infectious, immunological and genetic factors are involved. The diagnostic features of SAPHO syndrome are clinical and radiological. The most important diagnostic procedure is Tc-99 m bone scintigraphy but conventional x-rays as well as computed tomography (CT) and magnetic resonance imaging (MRI) can also contribute to the final diagnosis. Bone histology and positron emission tomography CT (PET-CT) may help to differentiate SAPHO syndrome from malignancies and infectious osteomyelitis. Nonsteroidal anti-inflammatory drugs (NSAIDs) are the cornerstone of treatment. The results obtained using antibiotics and disease-modifying antirheumatic drugs (DMARDs), such as sulfasalazine and methotrexate are inconsistent. Bisphosphonates and anti-tumor necrosis factor (anti-TNF) drugs have shown promising results in small studies but further research is still necessary. PMID:25260820

    Sotos syndrome is an overgrowth condition characterized by cardinal features including excessive growth during childhood, macrocephaly, distinctive facial gestalt and various degrees of learning difficulty, and associated with variable minor features. The exact prevalence remains unknown but hundreds of cases have been reported. The diagnosis is usually suspected after birth because of excessive height and occipitofrontal circumference (OFC), advanced bone age, neonatal complications including hypotonia and feeding difficulties, and facial gestalt. Other inconstant clinical abnormalities include scoliosis, cardiac and genitourinary anomalies, seizures and brisk deep tendon reflexes. Variable delays in cognitive and motor development are also observed. The syndrome may also be associated with an increased risk of tumors. Mutations and deletions of the NSD1 gene (located at chromosome 5q35 and coding for a histone methyltransferase implicated in transcriptional regulation) are responsible for more than 75% of cases. FISH analysis, MLPA or multiplex quantitative PCR allow the detection of total/partial NSD1 deletions, and direct sequencing allows detection of NSD1 mutations. The large majority of NSD1 abnormalities occur de novo and there are very few familial cases. Although most cases are sporadic, several reports of autosomal dominant inheritance have been described. Germline mosaicism has never been reported and the recurrence risk for normal parents is very low (<1%). The main differential diagnoses are Weaver syndrome, Beckwith-Wiedeman syndrome, Fragile X syndrome, Simpson-Golabi-Behmel syndrome and 22qter deletion syndrome. Management is multidisciplinary. During the neonatal period, therapies are mostly symptomatic, including phototherapy in case of jaundice, treatment of the feeding difficulties and gastroesophageal reflux, and detection and treatment of hypoglycemia. General pediatric follow-up is important during the first years of life to allow detection

    The occurrence of musculoskeletal manifestations (including synovitis, chest wall arthroosteitis and multifocal osteomyelitis) in association with severe acne, palmoplantar pustulosis and perhaps with some presentations of psoriasis, have been described by many authors in the past 30 years. These different multifaceted descriptions have been designated by a variety of terms. More recently, a possible link between these conditions and spondarthritides has also been underlined by a slightly increased prevalence of HLA B27 and occasional occurrences of sacroiliitis, chronic inflammatory bowel disease and possibly psoriasis. An acronym, the SAPHO syndrome (which stands for Synovitis, Acne, Pustulosis Hyperostosis and Osteitis) is proposed for this group of diseases because of the similarity of musculoskeletal manifestations in patients with severe acne and pustulosis. The clinical, epidemiological, pathophysiological, immunogenetic and diagnostic aspects, as well as the management of this syndrome are reviewed. PMID:7975935

    Paraneoplastic syndromes (PNS) comprise a diverse group of disorders that are associated with cancer but unrelated to the size, location, metastases, or physiologic activities of the mature tissue of origin. They are remote effects of tumors that may appear as signs, symptoms, or syndromes which can mimic other disease conditions encountered in veterinary medicine. Recognition of PNS is valuable for several reasons: the observed abnormalities may represent tumor cell markers and facilitate early diagnosis of the tumor; they may allow assessment of premalignant states; they may aid in the search metastases; they may help quantify and monitor response to therapy; and, they may provide insight into the study of malignant transformation and oncogene expression. This review will concentrate on the pathophysiology, diagnosis, and treatment of some of the common PNS encountered in veterinary medicine.

    2007-01-01

    First introduced as a new clinical entity in 1992, the Brugada syndrome is associated with a relatively high risk of sudden death in young adults, and occasionally in children and infants. Recent years have witnessed a striking proliferation of papers dealing with the clinical and basic aspects of the disease. Characterized by a coved-type ST-segment elevation in the right precordial leads of the electrocardiogram (ECG), the Brugada syndrome has a genetic basis that thus far has been linked only to mutations in SCN5A, the gene that encodes the α-subunit of the sodium channel. The Brugada ECG is often concealed, but can be unmasked or modulated by a number of drugs and pathophysiological states including sodium channel blockers, a febrile state, vagotonic agents, tricyclic antidepressants, as well as cocaine and propranolol intoxication. Average age at the time of initial diagnosis or sudden death is 40 ± 22, with the youngest patient diagnosed at 2 days of age and the oldest at 84 years. This review provides an overview of the clinical, genetic, molecular, and cellular aspects of the Brugada syndrome, incorporating the results of two recent consensus conferences. Controversies with regard to risk stratification and newly proposed pharmacologic strategies are discussed. PMID:17038146

    2014-01-01

    All living organisms must go through cycles of replicating their genetic information and then dividing the copies between two new cells. This cyclical process, in cells from bacteria and human alike, requires a protein complex known as cohesin. Cohesin is a structural maintenance of chromosomes (SMC) complex. While bacteria have one form of this complex, yeast have several SMC complexes, and humans have at least a dozen cohesin complexes alone. Therefore the ancient structure and function of SMC complexes has been both conserved and specialized over the course of evolution. These complexes play roles in replication, repair, organization, and segregation of the genome. Mutations in the genes that encode cohesin and its regulatory factors are associated with developmental disorders such as Roberts syndrome, Cornelia de Lange syndrome, and cancer. In this review, we focus on how acetylation of cohesin contributes to its function. In Roberts syndrome, the lack of cohesin acetylation contributes to nucleolar defects and translational inhibition. An understanding of basic SMC complex function will be essential to unraveling the molecular etiology of human diseases associated with defective SMC function. PMID:25054091

    Acrodysostosis (ADO) refers to a heterogeneous group of rare skeletal dysplasia that share characteristic features including severe brachydactyly, facial dysostosis and nasal hypoplasia. The literature describing acrodysostosis cases has been confusing because some reported patients may have had other phenotypically related diseases presenting with Albright Hereditary Osteodystrophy (AHO) such as pseudohypoparathyroidism type 1a (PHP1a) or pseudopseudohypoparathyroidism (PPHP). A question has been whether patients display or not abnormal mineral metabolism associated with resistance to PTH and/or resistance to other hormones that bind G-protein coupled receptors (GPCR) linked to Gsα, as observed in PHP1a. The recent identification in patients affected with acrodysostosis of defects in two genes, PRKAR1A and PDE4D, both important players in the GPCR-Gsα-cAMP-PKA signaling, has helped clarify some issues regarding the heterogeneity of acrodysostosis, in particular the presence of hormonal resistance. Two different genetic and phenotypic syndromes are now identified, both with a similar bone dysplasia: ADOHR, due to PRKAR1A defects, and ADOP4 (our denomination), due to PDE4D defects. The existence of GPCR-hormone resistance is typical of the ADOHR syndrome. We review here the PRKAR1A and PDE4D gene defects and phenotypes identified in acrodysostosis syndromes, and discuss them in view of phenotypically related diseases caused by defects in the same signaling pathway.

    There are numerous reports of multi-system genetic disorders with obesity. Many have a characteristic presentation and several, an overlapping phenotype indicating the likelihood of a shared common underlying mechanism or pathway. By understanding the genetic causes and functional perturbations of such syndromes we stand to gain tremendous insight into obesogenic pathways. In this review we focus particularly on Bardet-Biedl syndrome, whose molecular genetics and cell biology has been elucidated recently, and Prader-Willi syndrome, the commonest obesity syndrome due to loss of imprinted genes on 15q11-13. We also discuss highlights of other genetic obesity syndromes including Alstrom syndrome, Cohen syndrome, Albright's hereditary osteodystrophy (pseudohypoparathyroidism), Carpenter syndrome, MOMO syndrome, Rubinstein-Taybi syndrome, cases with deletions of 6q16, 1p36, 2q37 and 9q34, maternal uniparental disomy of chromosome 14, fragile X syndrome and Börjeson-Forssman-Lehman syndrome.

    Noonan Syndrome is one of the most common genetic syndromes and also an important differential diagnosis in children presenting with syndromic facies similar to Turner's syndrome phenotype. This syndrome is characterized by facial dysmorphism, congenital heart defects, short stature and also a wide phenotypic variation. This article discusses the case of a 10 year-old patient with Noonan syndrome that presented typical facies, cardiac defects (pulmonary dilatation and mitral regurgitation), dental malocclusion, micrognatism, short stature and a certain degree of learning disability.

    Among diseases that cause ichthyosis as one of the symptoms, there are some diseases that induce abnormalities in organs other than the skin. Of these, diseases with characteristic signs are regarded as syndromes. Although these syndromes are very rare, Netherton syndrome, Sjögren-Larsson syndrome, Conradi-Hünermann-Happle syndrome, Dorfman-Chanarin syndrome, ichthyosis follicularis, atrichia and photophobia (IFAP) syndrome, and Refsum syndrome have been described in texts as representative ones. It is important to know the molecular genetics and pathomechanisms in order to establish an effective therapy and beneficial genetic counseling including a prenatal diagnosis. PMID:26945533

    A 74-year-old gentleman was admitted to the regional neurosciences center with encephalopathy, myokymia, and dysautonomia. Chest imaging had previously identified an incidental mass in the anterior mediastinum, consistent with a primary thymic tumor. Antivoltage-gated potassium channel (anti-VGKC) antibodies were positive (titer 1273 pmol/L) and he was hypokalemic. Electromyogram and nerve conduction studies were in keeping with peripheral nerve hyperexcitability syndrome, and an electroencephalogram was consistent with encephalopathy. A diagnosis of Morvan syndrome was made, for which he was initially treated with high-dose steroids, followed by a 5-day course of intravenous immunoglobulin (IVIG) therapy. He also underwent thymectomy, followed by a postexcision flare of his symptoms requiring intensive care management. Further steroids, plasmapheresis, and IVIG achieved stabilization of his clinical condition, enabling transfer for inpatient neurorehabilitation. He was commenced on azathioprine and a prolonged oral steroid taper. A subsequent presumed incipient relapse responded well to further IVIG treatment. This case report documents a thymoma-associated presentation of anti-VGKC-positive Morvan syndrome supplemented by patient and carer narrative and video, both of which provide valuable further insights into this rare disorder. There are a limited number of publications surrounding this rare condition available in the English literature. This, combined with the heterogenous presentation, association with underlying malignancy, response to treatment, and prognosis, provides a diagnostic challenge. However, the association with anti-VGKC antibody-associated complexes and 2 recent case series have provided some scope for both accurate diagnosis and management. PMID:26740856

In many of the cases reported in the literature this typical constellation of symptoms is not complete; particularly the struma is not mandatorily involved. A 58-year-old patient with this rare disease who exhibited blepharochalasis and double upper and lower lip is presented. Additionally, subclinical hypothyroidism and alopecia areata totalis were found. In differential diagnosis other causes of double lips or enlargement of the lips must be considered. PMID:1817784

    Sciatic pain is often misleading and establishing the link with a local muscular cause can be difficult and lead to errors, especially when faced with a young sportsman, with typical discogenic pain. Simple, specific and reproducible tests enable a better identification and treatment of a muscular cause or canal syndrome. Physiotherapy, or local infiltrations are generally very efficient, and sufficient. Surgery may be considered only in a very limited number of cases, lack of response to the first line treatment and then only if it is the absolute diagnosis, diagnosis which must remain a diagnosis of exception, more so of exclusion.

    We report a case of Griscelli Syndrome (GS). Our patient initially presented with a diagnosis of haemophagocytic lymphistiocytosis (HLH). Subsequent microscopic analysis of the patient's hair follicle revealed abnormal distribution of melanosomes in the shaft, which is a hallmark for GS. Analysis of RAB27A gene in this patient revealed a homozygous mutation in exon 6, c.550C>T, p.R184X . This nonsense mutation causes premature truncation of the protein resulting in a dysfunctional RAB27A. Recognition of GS allows appropriate institution of therapy namely chemotherapy for HLH and curative haemotopoeitic stem cell transplantation. PMID:25500851

Chest examination was essentially normal and cardiovascular examination was suggestive of aortic regurgitation. Ears, nose and throat evaluation showed left vocal cord palsy and CT scan revealed an aortic arch aneurysm. Ortner's syndrome refers to hoarseness due to recurrent laryngeal nerve palsy secondary to a cardiovascular abnormality. Aortic aneurysms usually present with chest pain, back pain or epigastric pain, depending on the site of the aneurysm. An aortic arch aneurysm presenting as hoarseness is extremely rare.

    Tourette syndrome (Gilles de la Tourette disease) is a disorder of involuntary muscular tics, vocalizations and compulsive behavior. The tics and muscle movements vary in form and course; the complex repetitive patterns are eventually replaced by other patterns. The vocalization may be in the form of sounds, words or profanities and sometimes echolalia, echopraxia and palilalia. The onset may be from age two to 15 but is usually between ages eight and 12. Recent studies suggest that there is a hypersensitivity of dopamine receptors. Most patients respond well to haloperidol, but other drugs that may be of value include clonidine, pimozide, fluphenazine and trifluoroperazine. PMID:21286050

    The neuromuscular junction is vulnerable to autoimmune attack both at the pre-synaptic nerve terminal and at the post-synaptic muscle membrane. Antibodies directed to the nicotinic acetylcholine receptor at the muscle surface are the cause of myasthenia gravis in the majority of cases. Myasthenia gravis is an acquired condition, characterised by weakness and fatigability of the skeletal muscles. The ocular muscles are commonly affected first, but the disease often generalises. Treatment includes symptom control and immunosuppression. The thymus gland plays an important role in the pathogenesis of myasthenia gravis and thymectomy is indicated in certain subgroups. Lambert-Eaton myasthenic syndrome is associated with antibodies directed to the voltage-gated calcium channel antibodies at the pre-synaptic nerve terminal. It is an acquired condition and, in some cases, may be paraneoplastic, often secondary to underlying small cell lung carcinoma. Clinical presentation is distinct from myasthenia gravis, with patients often first presenting with lower limb muscle fatigability and autonomic symptoms. Congenital myasthenic syndromes are inherited neuromuscular disorders due to mutations in proteins at the neuromuscular junction. Various phenotypes exist depending on the protein mutation. Treatment is directed towards symptom control and immunosuppression is not indicated. PMID:21365067

    Klinefelter syndrome is the most common sex chromosome disorder. Affected males carry an additional X chromosome, which results in male hypogonadism, androgen deficiency, and impaired spermatogenesis. Some patients may exhibit all of the classic signs of this disorder, including gynecomastia, small testes, sparse body hair, tallness, and infertility, whereas others, because of the wide variability in clinical expression, lack many of these features. Treatment consists of testosterone replacement therapy to correct the androgen deficiency and to provide patients with appropriate virilization. This therapy also has positive effects on mood and self-esteem and has been shown to protect against osteoporosis, although it will not reverse infertility. Although the diagnosis of Klinefelter syndrome is now made definitively using chromosomal karyotyping, revealing in most instances a 47,XXY genotype, the diagnosis also can be made using a careful history and results of a physical examination, with the hallmark being small, firm testes. As it affects 1 in 500 male patients and presents with a variety of clinical features, primary care physicians should be familiar with this condition. PMID:9645824

    Hamartomatous polyposis syndromes are a diverse group of inherited conditions grouped together because they exhibit hamartomatous rather than epithelial polyp histology. Each syndrome exhibits characteristic polyp histology, gastrointestinal polyp distribution, gastrointestinal cancer risks, extra-intestinal benign findings and often extra-intestinal cancer risks. Identifying individuals at risk for these syndromes and accurately defining the precise diagnosis is necessary for planning surveillance and management in order to prevent the benign and malignant complications. Characteristic syndrome features including gastrointestinal findings, pathology, genetics, and management options for the three most common hamartomatous polyposis syndromes, Peutz-Jeghers syndrome, PTEN hamartoma tumor syndrome, and juvenile polyposis will be presented in this review.

    Polycystic ovary syndrome (PCOS) is a heterogeneous condition characterized by androgen excess, ovulatory dysfunction, and polycystic ovaries. It is the most common endocrinopathy among women of reproductive age, affecting between 6.5% and 8% of women, and is the most common cause of infertility. Insulin resistance is almost always present in women with PCOS, regardless of weight, and they often develop diabetes and metabolic syndrome. The Rotterdam criteria are widely used for diagnosis. These criteria require that patients have at least two of the following conditions: hyperandrogenism, ovulatory dysfunction, and polycystic ovaries. The diagnosis of PCOS also requires exclusion of other potential etiologies of hyperandrogenism and ovulatory dysfunction. The approach to PCOS management differs according to the presenting symptoms and treatment goals, particularly the patient's desire for pregnancy. Weight loss through dietary modifications and exercise is recommended for patients with PCOS who are overweight. Oral contraceptives are the first-line treatment for regulating menstrual cycles and reducing manifestations of hyperandrogenism, such as acne and hirsutism. Clomiphene is the first-line drug for management of anovulatory infertility. Metformin is recommended for metabolic abnormalities such as prediabetes, and a statin should be prescribed for cardioprotection if the patient meets standard criteria for statin therapy.

    An epidemic illness characterized by head nodding associated with onchocerciasis has been described in eastern Africa since the early 1960s; we summarize published reports and recent studies. Onset of nodding occurs in previously healthy 5–15-year-old children and is often triggered by eating or cold temperatures and accompanied by cognitive impairment. Its incidence has increased in Uganda and South Sudan over the past 10 years. Four case–control studies identified modest and inconsistent associations. There were nonspecific lesions seen by magnetic resonance imaging, no cerebrospinal fluid inflammation, and markedly abnormal electroencephalography results. Nodding episodes are atonic seizures. Testing has failed to demonstrate associations with trypanosomiasis, cysticercosis, loiasis, lymphatic filariasis, cerebral malaria, measles, prion disease, or novel pathogens; or deficiencies of folate, cobalamin, pyridoxine, retinol, or zinc; or toxicity from mercury, copper, or homocysteine.

    The antiphospholipid syndrome (APS) is an autoimmune systemic disease that is diagnosed when there is vascular thrombosis and/or pregnancy morbidity occurring with persistently positive antiphospholipid antibodies (aPL) (lupus anticoagulant test, anticardiolipin antibodies, and/or anti-beta(2)-glycoprotein I antibodies). Although International APS Classification Criteria have been formulated to provide a uniform approach to APS research, aPL may cause a spectrum of clinical manifestations, some of which are not included in these criteria. The main aPL-related cardiac manifestations include valve abnormalities (vegetations and/or thickening), myocardial infarction (MI), intracardiac thrombi, and myocardial microthrombosis. In this article, we will review the definition, etiopathogenesis, clinical manifestations, diagnosis, and treatment of aPL-related clinical events with emphasis on cardiac manifestations.

    Hepatopulmonary syndrome (HPS) is defined by the association of portal hypertension, increased alveolar-arterial oxygen gradient and intrapulmonary vascular dilations. Pathophysiological mechanisms of hypoxemia are characterized by ventilation-perfusion mismatch, oxygen diffusion limitation between alveolus and the centre of the dilated capillary, and right-to-left shunting. An excess of vasodilator molecules (like nitric monoxide) and proangiogenic factors (like VEGF) play an important role in the occurrence of HPS. Symptoms of HPS are not specific and dominated by a progressive dyspnea in upright position. Pulse oximetry is a simple non-invasive screening test but only detect the most severe forms of HPS. Medical treatment is disappointing and only liver transplantation may lead to resolution of HPS. Survival following liver transplantation is promising when hypoxemia is not severely decreased.

    Antiphospholipid syndrome (APS) is an autoimmune condition characterized by the occurrence of thrombosis (arterial and/or venous), often multiple, and/or pregnancy morbidity. Thrombosis is one of the major disease mechanisms, mainly caused by activating endothelial cells, monocytes, and platelets. At present, the management of APS patients with a history of thrombosis is based on long-term antithrombotic therapy, due to the high rate of recurrent thrombosis (29% per year without treatment). Obstetrical APS includes heterogeneous pregnancy complications whose pathogenesis has been increasingly elucidated in the past years. This is due to the current management and treatment, as 80% of APS patients achieve a live birth. The standard approach of APS is not supported by extensive evidence and the best options for refractory and incomplete cases need to be clarified. New and promising molecules are under investigation.

    Rett syndrome is one of the most common causes of complex disability in girls. It is characterized by early neurological regression that severely affects motor, cognitive and communication skills, by autonomic dysfunction and often a seizure disorder. It is a monogenic X-linked dominant neurodevelopmental disorder related to mutation in MECP2, which encodes the methyl-CpG-binding protein MeCP2. There are several mouse models either based on conditional knocking out of the Mecp2 gene or on a truncating mutation. We discuss the clinical aspects with special emphasis on the behavioral phenotype and we review current perspectives in clinical management alongside with perspectives in altering gene expression.

    A 34-year-old male patient was referred with a recalcitrant leg ulcer overlying an extensive vascular malformation, which had led several times to septic soft tissue infections. During his infancy he had been diagnosed to have Klippel-Trenaunay syndrome. Clinical examination revealed asymmetric hypertrophy of the lower extremities, an extensive portwine stain on the more severely affected left limb as well as prominent venous varicosities of both legs. Hands and feet showed striking cerebriform palmoplantar hypertrophy, and macrodactily with syndactily of several fingers. All toes had been amputated in early childhood due to extreme overgrowth and currently the patient walked on his forefeet in a prominent pes equinus deformity. Further symptoms consisted in several lipomas at both arms, another portwine stain at the left hemithorax and a single café-au-lait spot at the left scapula. Angio-magnetic resonance imaging scans of both legs showed an extensive venous-lymphatic vascular malformation involving the whole subcutis and infiltrating the muscle. The chronic wound was interpreted as venous stasis ulceration. Local percutaneous sclerotherapy of the dilated veins underneath the ulcer was discussed, but considered to carry a relevant risk of skin necrosis with consecutive progression of the wound. A conventional split-skin graft led to complete wound healing. Since, the patient consequently wears custom-made compression stockings and remained free from recurrences. The syndromatic constellation of palmoplantar overgrowth, multiple lipomas, giant fingers and toes, limb overgrowth, venous-lymphatic malformation and a café-au-lait spot led to the diagnosis of Proteus syndrome. The possible aetiology, clinical manifestations, differential diagnosis and management of this rare disorder are discussed. PMID:14524037

    Purpose of Review The different parkinsonian conditions can be challenging to separate clinically. This review highlights the important clinical features that guide the diagnosis of Parkinson disease (PD), progressive supranuclear palsy (PSP), multiple system atrophy (MSA), and corticobasal degeneration (CBD). Strategies for treatment and disease management are also discussed. Recent Findings Over the past decade there has been an increasing recognition of the broad clinical presentations of the neurodegenerative forms of parkinsonism. Nonmotor symptoms in these diseases, including psychiatric, cognitive, autonomic, and gastrointestinal dysfunction, appear to have a major impact on quality of life and disability. PSP and CBD are now considered pathologic diagnoses, with several different and varied clinical phenotypes, that overlap and share features with PDand frontotemporal dementia syndromes. PD is distinguished by its excellent response to dopaminergic medications that is maintained over many years, in contrast to the response seen in patients with MSA and PSP. New diagnostic criteria have been proposed for CBD. No new therapeutic interventions have emerged for PSP, MSA, or CBD. Infusional therapies and deep brain stimulation surgery are established therapies for advanced PD. Summary The “parkinsonian syndromes” encompass a number of nosologic entities that are grouped together on the basis of their shared clinical features but are separated on the basis of their different pathologies. Overall, the consideration of clinical signs, mode of disease onset, and nature of disease progression are all important to make a timely and definitive diagnosis. PMID:24092286

    Angelman syndrome combines severe mental retardation, epilepsy, ataxia, speech impairment, and unique behavior with happy demeanor, laughing, short attention span, hyperactivity, and sleep disturbance. Occurrence has been calculated at 1:20000 to 1:12000 constituting about 6% of all children with severe mental retardation and epilepsy. The physical "prototype" includes microcephaly with flat neck, fair skin and hair, wide-spaced teeth, and open mouth with tongue protrusion. Epilepsy is characterized by atypical absences, erratic myoclonus, and occasional tonic-clonic seizures. EEG demonstrates high-amplitude 2-3Hz delta activity with spike and slow-wave discharges and sleep-activated generalized epileptiform discharges. Sodium valproate, benzodiazepines, and priacetam are frequently used and effective. Development is generally slow, the majority attaining independent walking in the first 2.5-6 years. Vocabulary is limited to a few single words with superior speech and object apprehension. The condition is due to a lack of expression of the UBE3A gene on chromosome 15q. Maternal deletions of 15q11-13 produce the most pronounced phenotype (65-70% of probands), uniparental disomy and imprinting center mutations (10%), and UBE3A point mutations (11%) produce milder phenotypes.

    Most women of reproductive age have some physical discomfort or dysphoria in the weeks before menstruation. Symptoms are often mild, but can be severe enough to substantially affect daily activities. About 5–8% of women thus suffer from severe premenstrual syndrome (PMS); most of these women also meet criteria for premenstrual dysphoric disorder (PMDD). Mood and behavioural symptoms, including irritability, tension, depressed mood, tearfulness, and mood swings, are the most distressing, but somatic complaints, such as breast tenderness and bloating, can also be problematic. We outline theories for the underlying causes of severe PMS, and describe two main methods of treating it: one targeting the hypothalamus-pituitary-ovary axis, and the other targeting brain serotonergic synapses. Fluctuations in gonadal hormone levels trigger the symptoms, and thus interventions that abolish ovarian cyclicity, including long-acting analogues of gonadotropin-releasing hormone (GnRH) or oestradiol (administered as patches or implants), effectively reduce the symptoms, as can some oral contraceptives. The effectiveness of serotonin reuptake inhibitors, taken throughout the cycle or during luteal phases only, is also well established. PMID:18395582

    Boerhaave's syndrome or spontaneous oesophageal perforation, is a potentially lethal and frequently elusive medical condition which presents not only a diagnostic but also a therapeutic challenge. It is insufficiently considered in diagnostic hypotheses, yet may be confirmed or excluded by simple methods such as an erect chest film and a contrast study of the oesophagus. Errors in diagnosis are usually caused by unawareness of its varied and atypical presentations or failure to consider its possibility in acute cardiothoracic and upper gastrointestinal conditions. Early aggressive surgical intervention in the form of open and wide mediastinal and chest drainage, with or without oesophageal repair, resection or exclusion, offers the patient the best chance of survival against this otherwise invariably fatal event. Nonoperative therapy consisting of antibiotics, nil oral regimen, nasogastric tube suction, pleural drainage, H2 receptor blockers and either a feeding enterostomy or total parenteral nutrition, may also be appropriate in selected patients. It is probable that the condition is more common than is generally supposed. All clinicians need to be aware of this lethal disease, its frequently unusual presentations and the importance of early diagnosis. Images Figure 1 Figure 2 PMID:9196697

    Tourette's syndrome (TS) is a chronic disorder characterized by motor and vocal tics and a variety of associated behaviour disorders. Because current therapy is often unsatisfactory, there is expanding interest in new therapeutic strategies that are more effective, cause less side effects and ameliorate not only tics but also behavioural problems. From anecdotal reports and preliminary controlled studies it is suggested that - at least in a subgroup of patients - cannabinoids are effective in the treatment of TS. While most patients report beneficial effects when smoking marijuana (Cannabis sativa L.), available clinical trials have been performed using oral Δ⁹-tetrahydrocannabinol (THC). In otherwise treatment-resistant TS patients, therefore, therapy with THC should not be left unattempted. To date, it is unknown whether other drugs that interact with the endocannabinoid receptor system might be more effective in the treatment of TS than smoked marijuana or pure THC. Since it has been suggested that abnormalities within the endocannabinoid receptor system might underlie TS pathophysiology, it would be of interest to investigate the effect of substances that for example bind more selectively to the central cannabinoid receptor or inhibit the uptake or the degradation of different endocannabinoids.

    Calva, Daniel; Howe, James R.

    2009-01-01

    Synopsis Since the histological description of the hamartomatous polyp in 1957 by Horrilleno et al., several different syndromes have been described with the propensity to develop these polyps in the upper and lower GI tracts. These include Juvenile Polyposis, Peutz-Jeghers syndrome, hereditary mixed polyposis syndrome, and the PTEN hamartoma tumor syndromes (Cowden and Bannayan-Riley-Ruvalcaba syndromes), which are autosomal-dominantly inherited, and Cronkhite-Canada syndrome, which is acquired. The clinical aspects, the molecular pathogenesis, the organ systems affected, the risks of cancer, and the management of these hamartomatous polyposis syndromes will be reviewed in this paper. Although the incidence of these syndromes is low, it is important for clinicians to recognize these disorders in order to prevent morbidity and mortality in these patients, and to perform presymptomatic testing in patients at risk.

    CANDLE syndrome (chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature) is a recently described autoinflammatory syndrome characterized by early onset, recurrent fever, skin lesions, and multisystemic inflammatory manifestations. Most of the patients have been shown to have mutation in PSMB8 gene. Herein, we report a 2-year-old patient with young onset recurrent fever, atypical facies, widespread skin lesions, generalized lymphadenopathy, hepatosplenomegaly, joint contractures, hypertrglyceridemia, lipodystrophy, and autoimmune hemolytic anemia. Clinical features together with the skin biopsy findings were consistent with the CANDLE syndrome. The pathogenesis and treatment of this syndrome have not been fully understood. Increased awareness of this recently described syndrome may lead to recognition of new cases and better understanding of its pathogenesis which in turn may help for development of an effective treatment.

    PubMed

    Bresler, Scott C; Padwa, Bonnie L; Granter, Scott R

    2016-06-01

    Nevoid basal cell carcinoma syndrome, or basal cell nevus syndrome (Gorlin syndrome), is a rare autosomal dominantly inherited disorder that is characterized by development of basal cell carcinomas from a young age. Other distinguishing clinical features are seen in a majority of patients, and include keratocystic odontogenic tumors (formerly odontogenic keratocysts) as well as dyskeratotic palmar and plantar pitting. A range of skeletal and other developmental abnormalities are also often seen. The disorder is caused by defects in hedgehog signaling which result in constitutive pathway activity and tumor cell proliferation. As sporadic basal cell carcinomas also commonly harbor hedgehog pathway aberrations, therapeutic agents targeting key signaling constituents have been developed and tested against advanced sporadically occurring tumors or syndromic disease, leading in 2013 to FDA approval of the first hedgehog pathway-targeted small molecule, vismodegib. The elucidation of the molecular pathogenesis of nevoid basal cell carcinoma syndrome has resulted in further understanding of the most common human malignancy. PMID:26971503

    Fat embolism syndrome is an often overlooked cause of breathlessness in trauma wards. Presenting in a wide range of clinical signs of varying severity, fat embolism is usually diagnosed by a physician who keeps a high degree of suspicion. The clinical background, chronology of symptoms and corroborative laboratory findings are instrumental in a diagnosis of fat embolism syndrome. There are a few diagnostic criteria which are helpful in making a diagnosis of fat embolism syndrome. Management is mainly prevention of fat embolism syndrome, and organ supportive care. Except in fulminant fat embolism syndrome, the prognosis is usually good. PMID:23661916

    PubMed Central

    2010-01-01

    Hamartomatous polyposis syndromes are a rare group of hereditary autosomal dominant disorders that comprise less than 1% of all hereditary colorectal cancers. Hamartomatous polyps, in and of themselves, are benign entities; however, these hamartomatous polyposis syndromes have a malignant potential for the development of colorectal cancer as well as extracolonic cancers. Early detection and proper surveillance are vital to minimizing the risk of carcinoma. This article provides a critical review of the clinical presentation, pathology, genetics, and screening and surveillance guidelines of juvenile polyposis syndrome, PTEN hamartoma tumor syndrome, and Peutz-Jeghers syndrome.

  6. Barth syndrome

    PubMed Central

    2013-01-01

    First described in 1983, Barth syndrome (BTHS) is widely regarded as a rare X-linked genetic disease characterised by cardiomyopathy (CM), skeletal myopathy, growth delay, neutropenia and increased urinary excretion of 3-methylglutaconic acid (3-MGCA). Fewer than 200 living males are known worldwide, but evidence is accumulating that the disorder is substantially under-diagnosed. Clinical features include variable combinations of the following wide spectrum: dilated cardiomyopathy (DCM), hypertrophic cardiomyopathy (HCM), endocardial fibroelastosis (EFE), left ventricular non-compaction (LVNC), ventricular arrhythmia, sudden cardiac death, prolonged QTc interval, delayed motor milestones, proximal myopathy, lethargy and fatigue, neutropenia (absent to severe; persistent, intermittent or perfectly cyclical), compensatory monocytosis, recurrent bacterial infection, hypoglycaemia, lactic acidosis, growth and pubertal delay, feeding problems, failure to thrive, episodic diarrhoea, characteristic facies, and X-linked family history. Historically regarded as a cardiac disease, BTHS is now considered a multi-system disorder which may be first seen by many different specialists or generalists. Phenotypic breadth and variability present a major challenge to the diagnostician: some children with BTHS have never been neutropenic, whereas others lack increased 3-MGCA and a minority has occult or absent CM. Furthermore, BTHS was first described in 2010 as an unrecognised cause of fetal death. Disabling mutations or deletions of the tafazzin (TAZ) gene, located at Xq28, cause the disorder by reducing remodeling of cardiolipin, a principal phospholipid of the inner mitochondrial membrane. A definitive biochemical test, based on detecting abnormal ratios of different cardiolipin species, was first described in 2008. Key areas of differential diagnosis include metabolic and viral cardiomyopathies, mitochondrial diseases, and many causes of neutropenia and recurrent male miscarriage

  7. Metabolic syndrome and menopause

    PubMed Central

    2013-01-01

    Background The metabolic syndrome is defined as an assemblage of risk factors for cardiovascular diseases, and menopause is associated with an increase in metabolic syndrome prevalence. The aim of this study was to assess the prevalence of metabolic syndrome and its components among postmenopausal women in Tehran, Iran. Methods In this cross-sectional study in menopause clinic in Tehran, 118 postmenopausal women were investigated. We used the adult treatment panel 3 (ATP3) criteria to classify subjects as having metabolic syndrome. Results Total prevalence of metabolic syndrome among our subjects was 30.1%. Waist circumference, HDL-cholesterol, fasting blood glucose, diastolic blood pressure ,Systolic blood pressure, and triglyceride were significantly higher among women with metabolic syndrome (P-value<0.05). Our study shows high abdominal obesity and hypertension are the most prevalent components of metabolic syndrome. 15%, 13.3% and 1.8% of subjects had three, four and five criteria for metabolic syndrome, respectively. There was a significant relationship between number of components of metabolic syndrome and waist circumference. Conclusions Our study shows that postmenopausal status is associated with an increased risk of metabolic syndrome. Therefore, to prevent cardiovascular disease there is a need to evaluate metabolic syndrome and its components from the time of the menopause. PMID:23497470

    2011-01-01

    Impaired cardiac function leads to activation of the neurohumoral axis, sodium and water retention, congestion and ultimately impaired kidney function. This sequence of events has been termed the Cardiorenal Syndrome. This is different from the increase in cardiovascular complications which occur with primary kidney disease, that is, the so-called Renocardiac Syndrome. The present review discusses the pathogenesis of the Cardiorenal Syndrome followed by the benefits and potential deleterious effects of pharmacological agents that have been used in this setting. The agents discussed are diuretics, aquaretics, natriuretic peptides, vasodilators, inotropes and adenosine α1 receptor antagonists. The potential role of ultrafiltration is also briefly discussed.

    2002-01-01

    A tic is an involuntary, sudden, rapid, recurrent, nonrrhythmic, stereotyped, motor movement or vocalization. This paper reviews clinical, pathophysiological, epidemiological and treatment issues of tic disorders. The clinical presentation of tic disorders with simple and complex motor or vocal tics is reviewed in detail. The most common psychiatric comorbid conditions, such as personality disorder (PD), Obsessive-Compulsive Disorder (OCD), Self-Destructive Behavior (SDB) and Attention Deficit Hyperactivity Disorder (ADHD) are presented too. All forms of tics may be exacerbated by anger or stress, but they are usually markedly diminished during sleep. Premonitory feelings or "sensory experiences", which are distinct from the actual motor or phonic tics and precede the tics, occur in over 80% of tic-patients and in 95% of patients with Gilles de la Tourette Syndrome (GTS). The American Psychiatric Association recognizes three types of tic disorders on the basis of clinical criteria: Transient Tic Disorder, Chronic Motor or Vocal Tic Disorder and GTS. The diagnostic criteria for these types are described. According to epidemiological data, up to 10% of children have at least somewhere a transient tic disorder. The onset of tics, whether simple or multiple, occurs at approximately 7 years of age. The accepted prevalence figure for GTS is 0.05-3%. Although tics can appear as the result of brain injury, Huntington chorea or encephalitis, they are most commonly idiopathic. Genetic factors appear to be present in many but not in all cases of tic disorders. Autosomal dominant, sex-linked models or semirecessive-semidominant-oligogenic models have been considered. Based on the review of the literature we believe that tic disorders are related to altered neurotransmitter function within the CNS, especially that the functional abnormality is somehow related to dopaminergic mechanism. Several authors have recently investigated the possible role of autoimmune response to

    West syndrome is one of the most refractory epileptic syndromes in infancy, and many researchers have made great effort to find optimal treatment modalities for this syndrome. In this review, previous literature on optimal treatments of West syndrome and its refractory nature were briefly presented, followed by an introduction of recent publication of expert opinions from the US and Europe. An Asian expert opinion generated by a short questionnaire survey was then presented. It was shown that medically proven optimal treatment of West syndrome is not always the practical treatment of choice in Asian countries. Cost and geographical regions should also be taken into account in making practical choices for treatment of West syndrome. PMID:21196092

    Migraine and metabolic syndrome are highly prevalent and costly conditions. The two conditions coexist, but it is unclear what relationship may exist between the two processes. Metabolic syndrome involves a number of findings, including insulin resistance, systemic hypertension, obesity, a proinflammatory state, and a prothrombotic state. Only one study addresses migraine in metabolic syndrome, finding significant differences in the presentation of metabolic syndrome in migraineurs. However, controversy exists regarding the contribution of each individual risk factor to migraine pathogenesis and prevalence. It is unclear what treatment implications, if any, exist as a result of the concomitant diagnosis of migraine and metabolic syndrome. The cornerstone of migraine and metabolic syndrome treatments is prevention, relying heavily on diet modification, sleep hygiene, medication use, and exercise. PMID:23181051

    Modern oncology often obtains good results against earlier neoplasms, whilst it's still in difficulties against the advanced ones. The knowledge of paraneoplastic syndromes is crucial both to cure patients and to do an earlier diagnosis. When we recognize a paraneoplastic syndrome that comes before the clinic beginning of a neoplasm, perhaps we save a life. This review discusses all the main paraneoplastic syndromes, focusing mainly on their clinical aspect and reminding the most commonly associated cancers. PMID:16463565

    Compartment syndrome in children can present differently than adults. Increased analgesic need should be considered the first sign of evolving compartment syndrome in children. Children with supracondylar humerus fractures, floating elbow injuries, operatively treated forearm fractures, and tibia fractures are at high risk for developing compartment syndrome. Elbow flexion beyond 90° in supracondylar humerus fractures and closed treatment of forearm fractures in floating elbow injuries are associated with increased risk of compartment syndrome. Prompt diagnosis and treatment with fasciotomy in children result in excellent long-term outcomes. PMID:27241380

    The bilateral operculum syndrome, is a unique developmental syndrome. It is characterized by spastic paralysis of the muscles of the face, pharynx, and of mastication, as well as by epilepsy and mental retardation. Imaging studies show bilateral, structural abnormalities in the frontal, perisylvian region consistent with polymicrogyria. These children are usually diagnosed as suffering from cerebral palsy, but in the bilateral operculum syndrome, intelligence is relatively preserved despite the severe motor involvement. Misdiagnosis may lead to improper estimation of rehabilitation potential preventing appropriate therapy, especially in the field of alternative communication. We present a 3-year-old boy, apparently the first case of this syndrome to be described in Israel. PMID:8940497

They have been known for more than 40 years, but recently the discovery of new subgroups of paraneoplastic encephalitis syndromes with a remarkably good response to immune therapy has ignited new clinical and scientific interest. Knowledge of these subgroups and their associated autoantibodies is important in therapeutic decision-making. However, the abundance of new autoantibodies and syndromes can be confusing. This review paper summarizes current knowledge and new developments in the field of paraneoplastic neurological syndromes, their classification, pathophysiology and treatment. PMID:23937626

    Chronic pain of unknown aetiology, and characterized by cutaneous trigger points, has been coined the skinache syndrome. The treatment of the skinache syndrome was evaluated in 94 patients by two independent methods 2 years after treatment. After one subcutaneous injection of lidocaine 68% of the patients were cured. The pain recurred in 27 patients having suffered for an average of 2 years. Surgical removal of the cutaneous trigger points cured 77% of the latter patients. The odds ratio of success of surgical treatment versus all other treatments combined was 101.3. The skinache syndrome requires a precise clinical investigation. Even when the origin of the pain in tendons, muscle and adipose tissue is excluded, the skinache syndrome remains a common, debilitating disorder. In contrast to fibromyalgia, the skinache syndrome has a simple and effective cure. PMID:8537946

    We present a two-generation family with Brown syndrome. The proband was a six and a half-year-old female who presented with a history of failure of dextro-elevation of her left eye. A full ophthalmic evaluation was consistent with a left Brown syndrome. Family history revealed that her mother was operated on as a child for left Brown syndrome and examination of her four and a half-year-old sibling showed similar affection in the left eye. Autosomal dominant inheritance has been postulated in this condition. To our knowledge this is the first report of three members of a two-generation family with left-sided Brown syndrome. Genetic counseling of Brown syndrome cases is advised; nevertheless, identification of the responsible gene should shed more light on its genetics. PMID:18711279

    PubMed

    2001-10-01

    Cognitive syndromes are common clinical manifestations of hyperacute stroke and may be the single or dominant presenting features. They are related to acute dysfunction of complex integrated distributed functional networks serving different cognitive domains. The most common cortical syndromes include nonfluent or fluent aphasia, neglect, collor agnosia, pure alexia and Balint's syndrome. Disturbances of declarative memory are common following posterior cerebral artery and thalamic strokes. Abulia can follow thalamic, caudate and capsular lesions. Intraventricular and subarachnoid haemorrhages can cause preeminent neuropsychological changes. Disorientation is present in about 40% of acute stroke patients and delirium complicates the course of 25% of acute strokes. Some hyperacute cognitive stroke syndromes are useful indicators of later disability. Cognitive syndromes may pose special difficulties to neurology residents, unless formal teaching in neuropsychology and psychiatry is included in their training programs. PMID:11697519

    Epilepsy syndromes denote specific constellations of clinical seizure type(s), EEG findings, and other characteristic clinical features. Most syndromes recognized in epilepsy are genetic and developmental disorders that begin in the pediatric years. Epilepsy syndromes are divided into idiopathic (primary) types, in which the presumed etiology is genetic, versus symptomatic (secondary) types, in which there is either an underlying etiology that is known or presumed based on other evidence of brain dysfunction. Epilepsies are also classified by those with generalized seizures and those with localization-related seizures. Identification of a specific syndrome is important to define the best treatment and accurately prognosticate long-term outcome for children with epilepsy. In this chapter, clinical and electrographic features as well as inheritance patterns of common pediatric epilepsy syndromes are discussed. PMID:22810315

    The Nevoid Basal Cell Carcinoma Syndrome (NBCCS) is an uncommon disorder caused by a mutation in Patched, tumor suppressor gene. It is mainly characterized by numerous early onset basal cell carcinomas, odontogenic cysts of jaw and skeletal abnormalities. Due to the wide clinical spectrum, treatment and management of its modalities are not standardized and should be individualized and monitored by a multidisciplinary team. We report a typical case in a 30-year-old man with multiple basal cell carcinomas, keratotic pits of palmar creases and bifid ribs, with a history of several corrective surgeries for keratocystic odontogenic tumors, among other lesions characteristic of the syndrome.

    Coinciding with the increasing rates of cannabis abuse has been the recognition of a new clinical condition known as Cannabinoid Hyperemesis Syndrome. Cannabinoid Hyperemesis Syndrome is characterized by chronic cannabis use, cyclic episodes of nausea and vomiting, and frequent hot bathing. Cannabinoid Hyperemesis Syndrome occurs by an unknown mechanism. Despite the well-established anti-emetic properties of marijuana, there is increasing evidence of its paradoxical effects on the gastrointestinal tract and CNS. Tetrahydrocannabinol, cannabidiol, and cannabigerol are three cannabinoids found in the cannabis plant with opposing effects on the emesis response. The clinical course of Cannabinoid Hyperemesis Syndrome may be divided into three phases: prodromal, hyperemetic, and recovery phase. The hyperemetic phase usually ceases within 48 hours, and treatment involves supportive therapy with fluid resuscitation and anti-emetic medications. Patients often demonstrate the learned behavior of frequent hot bathing, which produces temporary cessation of nausea, vomiting, and abdominal pain. The broad differential diagnosis of nausea and vomiting often leads to delay in the diagnosis of Cannabinoid Hyperemesis Syndrome. Cyclic Vomiting Syndrome shares several similarities with CHS and the two conditions are often confused. Knowledge of the epidemiology, pathophysiology, and natural course of Cannabinoid Hyperemesis Syndrome is limited and requires further investigation. PMID:22150623

    HELLP syndrome was first described in 1982 by Weinstein et al. and the term HELLP refers to an acronym used to describe the clinical condition that leads to hemolysis, elevated liver enzymes and low platelets. The syndrome frequency varies from 0.5 to 0.9% pregnancies and manifests preferentially between the 27th and 37th week of gestation. Approximately 30% of cases occur after delivery. Although the etiopathogenesis of this syndrome remains unclear, histopathologic findings in the liver include intravascular fibrin deposits that presumably may lead to hepatic sinusoidal obstruction, intrahepatic vascular congestion, and increased intrahepatic pressure with ensuing hepatic necrosis, intraparenchymal and subcapsular hemorrhage, and eventually capsular rupture. Typical clinical symptoms of HELLP syndrome are pain in the right upper quadrant abdomen or epigastric pain, nausea and vomiting. However, this syndrome can present nonspecific symptoms and the diagnosis may be difficult to be established. Laboratory tests and imaging exams are essential for differential diagnosis with other clinical conditions. Treatment of HELLP syndrome with corticosteroids, targeting both lung maturation of the fetus is still an uncertain clinical value. In conclusion, three decades after the tireless efforts of Dr. Weinstein to characterize HELLP syndrome, it remains a challenge to the scientific community and several questions need to be answered for the benefit of pregnant women.

    Although perceived as a rare condition, joint hypermobility syndrome is common. Its prevalence in rheumatology clinics is extremely high. Early estimates suggest that it may be the most common of all rheumatologic conditions. The problem lies in the general lack of awareness of the syndrome, its means of recognition, and the resultant failure to diagnose it correctly when present. It is a worldwide problem. This article provides an overview of hypermobility and hypermobility syndrome, stressing its multisystemic nature and the negative impact that it may have on quality of life, with particular reference to gastrointestinal involvement.

We are reporting a case with two episodes of MFS within two years. Initially he presented with partial ophthalmoplegia, ataxia. Second episode was characterized by full-blown presentation characterized by ataxia, areflexia and ophthalmoplegia. CSF analysis was typical during both episodes. Nerve conduction velocity study was fairly within normal limits. MRI of brain was within normal limits. He responded to symptomatic measures initially, then to steroids in the second episode. We are reporting the case due to its rarity. PMID:15645989

    The refeeding syndrome is frequent and potentially deadly, still it is underdiagnosed. It is defined by clinical and biological manifestations that are seen upon refeeding of malnourished patients. It is the consequence of the transition from catabolism to anabolism. Ions intracellular shift caused by insulin and B1 vitamin deficiency are fundamental in the development of this syndrome. Riskconditions are well summarized by the NICE criteria. To avoid refeeding syndrome, it is fundamental to find and correct any electrolytic deficiency and to give thiamine before starting a slow and progressive oral, enteral or parenteral refeeding.

In the case of a non-radiating black hole, the timescale of the syndrome is inversely proportional to the initial mass of the black hole. In the case of a radiating black hole, on the other hand, the syndrome time is of the order of the Eddington time. The radiating black hole in the Earth would act as a strong heat source.

    2013-01-01

    Background: Coxa saltans refers to a constellation of diagnoses that cause snapping of the hip and is a major cause of anterior hip pain in dancers. When the internal type is accompanied by weakness or pain, it is referred to as iliopsoas syndrome. Iliopsoas syndrome is the result of repetitive active hip flexion in abduction and can be confused with other hip pathology, most commonly of labral etiology. Purpose: To report the incidence, clinical findings, treatment protocol, and results of treatment for iliopsoas syndrome in a population of dancers. Study Design: Retrospective case series; Level of evidence, 4. Methods: A retrospective database review of 653 consecutive patients evaluated for musculoskeletal complaints over a 3-year period was completed. The diagnosis of iliopsoas syndrome was made based on anterior hip or groin pain, weakness with resisted hip flexion in abduction, or symptomatic clicking or snapping with a positive iliopsoas test. Patients identified with iliopsoas syndrome were further stratified according to age at time of onset, insidious versus acute onset, duration of symptoms, side of injury, presence of rest pain, pain with activities of daily living, and associated lower back pain. All patients diagnosed with iliopsoas syndrome underwent physical therapy, including hip flexor stretching and strengthening, pelvic mobilization, and modification of dance technique or exposure as required. Results: A total of 49 dancers were diagnosed and treated for iliopsoas syndrome. Within this injured population of 653 patients, the incidence in female dancers was 9.2%, significantly higher than that in male dancers (3.2%). The mean age at the time of injury was 24.6 years. The incidence of iliopsoas syndrome in dancers younger than 18 years was 12.8%, compared with 7% in dancers older than 18 years. Student dancers had the highest incidence (14%), followed by amateur dancers (7.5%), while professional dancers had the lowest incidence (4.6%). All

    The authors describe a case of Cowden´s syndrome in a female patient with classic cutaneous lesions, plus papillomatous lesions in the gastrointestinal tract and a previous history of thyroid carcinoma. Mucocutaneous lesions occur in 90% of Cowden's syndrome cases and are characterized by facial trichilemmomas, oral mucosal papillomas and benign acral keratoses. Sites of extracutaneous involvement include: the thyroid, gastrointestinal tract, breast and endometrial tissue. There is risk of malignancies in these organs and they need to be monitored with imaging tests. The early diagnosis of the syndrome by a dermatologist through mucocutaneous lesions enables the investigation and diagnosis of extracutaneous involvement. PMID:25672315

    Anton's syndrome is arguably the most striking form of anosognosia. Patients with this syndrome behave as if they can see despite their obvious blindness. Although best known for his description of asomatognosia and visual anosognosia, Gabriel Anton (1858-1933) made other significant contributions to the clinical neurosciences, including pioneering work in neurosurgery, neuropsychology, and child psychiatry. However, it has not been recognized in the English literature that Anton was also a dedicated advocate of eugenics and racial hygiene. This paper provides a case of Anton's syndrome and puts the works of Gabriel Anton into their historic context. PMID:21779298

  3. TP53 p.R337H is a conditional cancer-predisposing mutation: further evidence from a homozygous patient

    PubMed Central

    2013-01-01

    Background Adrenocortical carcinomas (ACCs) are among the most common childhood cancers occurring in infants affected with the Li-Fraumeni and Li- Fraumeni-like (LFS/LFL) syndromes, which are caused by dominant germline mutations in the TP53 gene. In Brazil, a particular mutation, occurring in the tetramerisation domain of the gene, p.R337H, is exceedingly common due to a founder effect and is strongly associated with ACC. In this report, we describe the phenotype and long-term clinical follow-up of a female child diagnosed with ACC and homozygous for the TP53 p.R337H founder mutation. Case presentation At age 11 months, the patient was diagnosed with a virilising anaplastic adrenal cortical tumour, which was completely excised without disturbing the adrenal capsule. Family history was consistent with an LFL tumour pattern, and genotyping identified the TP53 p.R337H mutation in both alleles in genomic DNA from lymphocytes and fibroblasts. Haplotype analysis confirmed the occurrence of the mutation in the same founder haplotype previously described in other Brazilian patients. No other germline or somatic TP53 mutations or rearrangements were identified. At age 9 years, the child was asymptomatic and had no evidence of endocrine derangements. Full body and brain magnetic resonance imaging (MRI) failed to detect any suspicious proliferative lesions, and cardiopulmonary exercise testing results were within the normal reference for the child’s age, ruling out a major exercise capacity deficiency. Conclusion This is the first clinical and aerobic functional capacity documentation of a patient who carries two mutant TP53 alleles and no wild-type allele. Our results support the hypothesis that TP53 p.R337H, the most common TP53 mutation ever described in any population, is a conditional mutant. Furthermore, our observations over a long period of clinical follow-up suggest that TP53 p.R337H homozygotes do not have a more severe disease phenotype than do heterozygote

  4. PHACE(S) syndrome.

    PubMed

    Heyer, Geoffrey L

    2015-01-01

    PHACE(S) syndrome is a neurocutaneous disorder of unknown etiology. The acronym refers to the commonest features of PHACE: posterior fossa malformations, large facial hemangiomas, cerebral arterial anomalies, cardiovascular anomalies, and eye anomalies. When ventral developmental defects such as sternal clefting or supraumbilical raphe occur, the PHACES acronym may be used. The hallmark feature of PHACE is the presence of one or more large facial infantile hemangiomas that occupy at least one facial segment. Infantile hemangiomas differ from the capillary malformation (port wine stain) of Sturge-Weber syndrome, and the arteriovenous malformation of Wyburn-Mason syndrome, distinguishing PHACE syndrome from other neurocutaneous disorders with red birthmarks. The true incidence of PHACE has not yet been established. Girls are more commonly affected than boys. Cerebral vascular anomalies are probably the most common extracutaneous feature. Given that several organ systems are involved, a multidisciplinary approach to disease surveillance and treatment is advised. PMID:26564079

    Leylls syndrome (syndrome of toxic epidermal necrolysis) is a rare disease, firstly described by Scottish doctor of medicine Allan Lyell in 1956. It is characterized by huge skin and mucosa necrolysis, which affects at least 30 % of body surface, and systemic symptoms. According to the frequency of the occurrence it is an extremely rare condition, with an incidence of 0.5-2 cases per million residents per year. Leylls syndrome is considered as a toxoallergic reaction, triggered mostly by some medication and it is associated with a very high mortality rate (in the literature reported between 30 to 90 %). Adequate and timely local and systemic treatment at the Intensive Care Unit or at the specialized clinic can improve the overall poor prognosis of the patients. In our case report we describe a very rare case of the Lyells syndrome after exposure to the antifungal organosulfur compound, which is widely used by the homegardners and farmers. PMID:26967239

    Enduring and disabling fatigue that cannot be explained by a known disease is the main characteristic of chronic fatigue syndrome. Several definitions do exist, and classification approaches vary regarding supplementary symptoms, time course, and by implicit concepts of aetiology. CFS can be considered as a functional somatic syndrome, e. g. supported by the high rates of comorbid bodily complaints and syndromes that lack clear medical explanation. Accordingly the diagnostic process should not be limited to the thorough physical examination, but also address additional somatic complaints, psychosocial factors (specifically subjective illness beliefs), and impairments. Recently German medical and psychological societies provided treatment guidelines for functional somatic syndromes. Cognitive behavioural therapy and graded activity are evidence based treatment methods for CFS. PMID:23250694

    PubMed

    Rom, Eyal; Tenenbaum, Shay; Chechick, Ofir; Burstein, Gideon; Amit, Yehuda; Thein, Ran

    2013-10-01

    Chronic exertional compartment syndrome is an uncommon phenomenon first reported in the mid 50's. This condition is characterized by sharp pain during physical activity, causing reduction in activity frequency or intensity and even abstention. This syndrome is caused by elevation of the intra-compartmental pressure which leads to decreased tissue perfusion, thus ischemic damage to the tissue ensues. Chronic exertional syndrome is usually related to repetitive physical activity, usually in young people and athletes. The physical activity performed by the patient causes a rise in intra-compartmental pressure and thereby causes pain. The patient discontinues the activity and the pain subsides within minutes of rest. Chronic exertional syndrome is reported to occur in the thigh, shoulder, arm, hand, foot and gluteal region, but most commonly in the leg, especially the anterior compartment. The diagnosis of chronic exertional syndrome is primarily based on patients' medical history, supported by intramuscular pressure measurement of the specific compartment involved. Treatment of chronic exertional syndrome, especially the anterior and lateral compartment of the leg is mainly by surgery i.e. fasciotomy. If the patient is reluctant to undergo a surgical procedure, the conservative treatment is based on abstention from the offending activity, changing footwear or using arch support. However, the conservative approach is not as successful as surgical treatment. PMID:24450036

  10. Muir-Torre Syndrome

    PubMed Central

    Feser, Christina; Grekin, Steven

    2016-01-01

    Muir-Torre syndrome is a rare, autosomal dominant genodermatosis characterized by the presence of at least one sebaceous gland neoplasm, associated with an underlying visceral malignancy. Muir-Torre syndrome is believed to be a subtype of Lynch Syndrome. Affected individuals are found to have germline mutations predominantly in DNA mismatch repair gene MSH2, and much less frequently, MLH1. The authors report the case of a 55-year-old woman presenting with multiple cutaneous neoplasms including sebaceoma, basal cell carcinoma, and squamous cell carcinoma; personal history of colorectal and endometrial cancer; and family history of colorectal cancer; found to have a deletion at mismatch repair gene MLH1. It is important to recognize the role of these less common gene deletions in producing the Muir-Torre syndrome phenotype, and consider the correlation of cutaneous manifestations with internal disease. The authors discuss the clinical presentation of Muir-Torre syndrome, methods of diagnosis, and the importance of regular medical surveillance to detect and prevent disease progression in Muir-Torre syndrome patients and their family members. PMID:26962393

  11. Hamartomatous polyposis syndromes: A review

    PubMed Central

    2014-01-01

    Hamartomatous Polyposis Syndromes (HPS) are genetic syndromes, which include Peutz-Jeghers syndrome, Juvenile polyposis syndrome, PTEN hamartoma tumour syndrome (Cowden Syndrom, Bannayan-Riley-Ruvalcaba and Proteus Syndrome) as well as hereditary mixed polyposis syndrome. Other syndromes such as Gorlin Syndrome and multiple endocrine neoplasia syndrome 2B are sometimes referred to as HPS. HPS is characterized by the development of hamartomatous polyps in the gastrointestinal tract as well as several extra-intestinal findings such as dermatological and dysmorphic features or extra-intestinal cancer. The syndromes are rare and inherited in an autosomal dominant manner. The diagnosis of HPS has traditionally been based on clinical criteria, but can sometimes be difficult as the severity of symptoms range considerably from only a few symptoms to very severe cases - even within the same family. De novo cases are also frequent. However, because of the discovery of several associated germline-mutations as well as the rapid development in genetics it is now possible to use genetic testing more often in the diagnostic process. Management of the syndromes is different for each syndrome as extra-intestinal symptoms and types of cancers differs. Clinical awareness and early diagnosis of HPS is important, as affected patients and at-risk family members should be offered genetic counselling and surveillance. Surveillance in children with HPS might prevent or detect intestinal or extra-intestinal complications, whereas in adulthood surveillance is recommended due to an increased risk of cancer e.g. intestinal cancer or breast cancer.

    Acute radiation syndrome (ARS) or sickness or poisoning or toxicity is induced after a whole body exposure of men to high doses of radiation between 1-12Gy. First symptoms are from the gastrointestinal system, which together with bone marrow are the most sensitive parts of our body. Chronic radiation syndrome (CRS) may be induced by smaller than 1Gy radiation doses or after a mild form of ARS. Prophylaxis and treatment suggestions are described. In cases of ARS, a large part of the exposed population after proper medical care may survive, while without medical care this part of the population will be lost. Prophylaxis may also save another part of the population. PMID:23570025

    PubMed

    Kumar, Ashok; Agarwal, Sarita

    2014-12-01

    Marfan syndrome (MFS), a relatively common autosomal dominant hereditary disorder of connective tissue with prominent manifestations in the skeletal, ocular, and cardiovascular systems, is caused by mutations in the glycoprotein gene fibrillin-1 (FBN1). Aortic root dilation and mitral valve prolapse are the main presentations among the cardiovascular malformations of MFS. The revised Ghent diagnostics nosology of Marfan syndrome is established in accordance with a combination of major and minor clinical manifestations in various organ systems and the family history. The pathogenesis of Marfan syndrome has not been fully elucidated. However, fibrillin-1 gene mutations are believed to exert a dominant negative effect. The treatment includes prophylactic β-blockers and angiotensin II-receptor blockers in order to slow down the dilation of the ascending aorta and prophylactic aortic surgery. Importantly, β-blocker therapy may reduce TGF-β activation, which has been recognized as a contributory factor in MFS. The identification of a mutation allows for early diagnosis, prognosis, genetic counseling, preventive management of carriers and reassurance for unaffected relatives. The importance of knowing in advance the location of the putative family mutation is highlighted by its straightforward application to prenatal and postnatal screening. The present article aims to provide an overview of this rare hereditary disorder. PMID:25606393

    2008-01-01

    Nevoid basal cell carcinoma syndrome (NBCCS), also known as Gorlin syndrome, is a hereditary condition characterized by a wide range of developmental abnormalities and a predisposition to neoplasms. The estimated prevalence varies from 1/57,000 to 1/256,000, with a male-to-female ratio of 1:1. Main clinical manifestations include multiple basal cell carcinomas (BCCs), odontogenic keratocysts of the jaws, hyperkeratosis of palms and soles, skeletal abnormalities, intracranial ectopic calcifications, and facial dysmorphism (macrocephaly, cleft lip/palate and severe eye anomalies). Intellectual deficit is present in up to 5% of cases. BCCs (varying clinically from flesh-colored papules to ulcerating plaques and in diameter from 1 to 10 mm) are most commonly located on the face, back and chest. The number of BBCs varies from a few to several thousand. Recurrent jaw cysts occur in 90% of patients. Skeletal abnormalities (affecting the shape of the ribs, vertebral column bones, and the skull) are frequent. Ocular, genitourinary and cardiovascular disorders may occur. About 5–10% of NBCCS patients develop the brain malignancy medulloblastoma, which may be a potential cause of early death. NBCCS is caused by mutations in the PTCH1 gene and is transmitted as an autosomal dominant trait with complete penetrance and variable expressivity. Clinical diagnosis relies on specific criteria. Gene mutation analysis confirms the diagnosis. Genetic counseling is mandatory. Antenatal diagnosis is feasible by means of ultrasound scans and analysis of DNA extracted from fetal cells (obtained by amniocentesis or chorionic villus sampling). Main differential diagnoses include Bazex syndrome, trichoepithelioma papulosum multiplex and Torre's syndrome (Muir-Torre's syndrome). Management requires a multidisciplinary approach. Keratocysts are treated by surgical removal. Surgery for BBCs is indicated when the number of lesions is limited; other treatments include laser ablation, photodynamic

    CHARGE syndrome, or Hall-Hitner syndrome (HHS), has been delineated as a common syndrome that includes coloboma, choanal atresia, cranial nerve dysfunction (particularly asymmetric facial palsy and neurogenic swallowing problems), characteristic ear abnormalities, deafness with hypoplasia of the cochlea and semicircular canals, genital hypoplasia, and variable heart defects, orofacial clefting, tracheo-esophageal fistula, renal anomalies, thymic/parathyroid hypoplasia, spine anomalies, short broad neck with sloping shoulders, and characteristic facial features. We conducted behavioral and personality assessments in 14 boys with HHS syndrome aged 6-21 years, and compared their characteristics with similar data from 20 age-matched boys with Down syndrome (DS), 17 boys with Prader-Willi syndrome (PWS), and 16 boys with Williams syndrome (WS). We used the Reiss Profile of Fundamental Goals and Motivation Sensitivities, the Achenbach Child Behavior Checklist (CBCL), and the Aberrant Behavior Checklist (ABC). All 14 boys with HHS were legally deaf, and 10 of the 14 were also legally blind. In comparison these other syndromes, boys with HHS had behavior that resembled autistic spectrum disorder. They were socially withdrawn, lacked interest in social contact, and manifested reduced seeking of attention from others, with hyperactivity and a need to maintain order. Though the boys with HHS showed decreased social interaction, they were not as socially impaired as in classic autism. Their language was delayed due to dual sensory impairment, cranial nerve deficits, and chronic medical problems, but their language style was not abnormal (no echolalia or jargon, no scripted phrases, and no pronoun reversal). Boys with HSS appeared frustrated, but they were not aggressive, or at risk for delinquency, manifesting few stereotypic behaviors or unusual preoccupations. They did not have a restricted repertoire of activities and interests. Their behavioral features appeared to be due

  1. Sturge-Weber syndrome.

    Comi, Anne M

    2015-01-01

    Sturge-Weber syndrome is the third most common neurocutaneous disorder, after neurofibromatosis and tuberous sclerosis, and impacts approximately 1 in 20000 live births. Sturge-Weber syndrome is not inherited, but rather occurs exclusively sporadically, in both males and females and in all races and ethnic backgrounds. Sturge-Weber syndrome presents at birth with a capillary malformation on the face (port-wine birthmark) with later diagnosis of abnormal vasculature in the eye and the brain which result in a range of complications. The underlying somatic mosaic mutation causing both Sturge-Weber syndrome and isolated port-wine birthmarks was recently discovered and is an activating mutation in GNAQ. When a newborn presents with a facial port-wine birthmark on the upper face, that child has a 15-50% risk of developing Sturge-Weber syndrome brain and/or eye involvement, depending on the extent of the birthmark, and close monitoring and appropriate screening is essential for early diagnosis and optimal treatment. Treatment options include laser therapy for lightening of the birthmark, eye drops and surgery for glaucoma management, and aggressive anticonvulsant treatment, low dose aspirin, and neurosurgery where necessary. Future possible treatments based upon new knowledge of the somatic mutation and downstream pathways are currently being considered and studied. PMID:26564078

    Carpal tunnel syndrome is a neuropathy resulting from compression of the median nerve as it passes through a narrow tunnel in the wrist on its way to the hand. The lack of precise objective and clinical tests, along with symptoms that are synonymous with other syndromes in the upper extremity, cause carpal tunnel syndrome to appear to be a rare entity in athletics. However, it should not be ruled out as a possible etiology of upper extremity paralysis in the athlete. More typically, carpal tunnel syndrome is the most common peripheral entrapment neuropathy encountered in industry. Treatment may include rest and/or splinting of the involved wrist, ice application, galvanic stimulation, or iontophoresis to reduce inflammation, and then transition to heat modalities and therapeutic exercises for developing flexibility, strength, and endurance. In addition, an ergonomic assessment should be conducted, resulting in modifications to accommodate the carpal tunnel syndrome patient. ImagesFig 3.Fig 4.Fig 5.Fig 6.Fig 7. PMID:16558255

    PubMed Central

    Walker, Ruth H.

    2015-01-01

    Background The two core neuroacanthocytosis (NA) syndromes, chorea-acanthocytosis (ChAc) and McLeod syndrome, are progressive neurodegenerative disorders that primarily affect the basal ganglia. The characteristic phenotype comprises a variety of movement disorders including chorea, dystonia, and parkinsonism, as well as psychiatric and cognitive symptoms attributable to basal ganglia dysfunction. These disorders are symptomatically managed on a case-by-case basis, with very few practitioners seeing more than a single case in their careers. Methods A literature search was performed on PubMed utilizing the terms neuroacanthocytosis, chorea-acanthocytosis, and McLeod syndrome, and articles were reviewed for mentions of therapies, successful or otherwise. Results There have been no blinded, controlled trials and only one retrospective case series describing ChAc. The various therapies that have been used in patients with NA syndromes are summarized. Discussion Management remains at present purely symptomatic, which is similar in principle to other more common basal ganglia neurodegenerative disorders such as Huntington’s disease (HD) and Parkinson’s disease (PD). However, there are some specific issues particular to NA syndromes that merit attention. An integrated multidisciplinary approach is the ideal management strategy for these complex and multifaceted neurodegenerative disorders. PMID:26504667

  4. Complex regional pain syndrome.

    PubMed

    Bruehl, Stephen

    2015-01-01

    Complex regional pain syndrome is a chronic pain condition characterized by autonomic and inflammatory features. It occurs acutely in about 7% of patients who have limb fractures, limb surgery, or other injuries. Many cases resolve within the first year, with a smaller subset progressing to the chronic form. This transition is often paralleled by a change from "warm complex regional pain syndrome," with inflammatory characteristics dominant, to "cold complex regional pain syndrome" in which autonomic features dominate. Multiple peripheral and central mechanisms seem to be involved, the relative contributions of which may differ between individuals and over time. Possible contributors include peripheral and central sensitization, autonomic changes and sympatho-afferent coupling, inflammatory and immune alterations, brain changes, and genetic and psychological factors. The syndrome is diagnosed purely on the basis of clinical signs and symptoms. Effective management of the chronic form of the syndrome is often challenging. Few high quality randomized controlled trials are available to support the efficacy of the most commonly used interventions. Reviews of available randomized trials suggest that physical and occupational therapy (including graded motor imagery and mirror therapy), bisphosphonates, calcitonin, subanesthetic intravenous ketamine, free radical scavengers, oral corticosteroids, and spinal cord stimulation may be effective treatments. Multidisciplinary clinical care, which centers around functionally focused therapies is recommended. Other interventions are used to facilitate engagement in functional therapies and to improve quality of life. PMID:26224572

    Introduction The hepatopulmonary syndrome has been acknowledged as an important vascular complication in lungs developing systemic hypoxemia in patients with cirrhosis and portal hypertension. Is formed by arterial oxygenation abnormalities induced from intrapulmonary vascular dilatations with liver disease. It is present in 4-32% of patients with cirrhosis. It increases mortality in the setting of cirrhosis and may influence the frequency and severity. Initially the hypoxemia responds to low-flow supplemental oxygen, but over time, the need for oxygen supplementation is necessary. The liver transplantation is the only effective therapeutic option for its resolution. Aim To update clinical manifestation, diagnosis and treatment of this entity. Method A literature review was performed on management of hepatopulmonary syndrome. The electronic search was held of the Medline-PubMed, in English crossing the headings "hepatopulmonary syndrome", "liver transplantation" and "surgery". The search was completed in September 2013. Results Hepatopulmonary syndrome is classically defined by a widened alveolar-arterial oxygen gradient (AaPO2) on room air (>15 mmHg, or >20 mmHg in patients >64 years of age) with or without hypoxemia resulting from intrapulmonary vasodilatation in the presence of hepatic dysfunction or portal hypertension. Clinical manifestation, diagnosis, classification, treatments and outcomes are varied. Conclusion The severity of hepatopulmonary syndrome is an important survival predictor and determine the improvement, the time and risks for liver transplantation. The liver transplantation still remains the only effective therapeutic. PMID:25004294

    2014-01-01

    Short stature is one of the major components of many dysmorphic syndromes. Growth failure may be due to a wide variety of mechanisms, either related to the growth hormone (GH)/insulin-like growth factor axis or to underlying unknown pathologies. In this review, the relatively more frequently seen syndromes with short stature (Noonan syndrome, Prader-Willi syndrome, Silver-Russell syndrome and Aarskog-Scott syndrome) were discussed. These disorders are associated with a number of endocrinopathies, as well as with developmental, systemic and behavioral issues. At present, GH therapy is used in most syndromic disorders, although long-term studies evaluating this treatment are insufficient and some controversies exist with regard to GH dose, optimal age to begin therapy and adverse effects. Before starting GH treatment, patients with syndromic disorders should be evaluated extensively. PMID:24637303

    Esteve-Valverde, E; Ferrer-Oliveras, R; Alijotas-Reig, J

    2016-04-01

    Obstetric antiphospholipid syndrome is an acquired autoimmune disorder that is associated with various obstetric complications and, in the absence of prior history of thrombosis, with the presence of antiphospholipid antibodies directed against other phospholipids, proteins called cofactors or PL-cofactor complexes. Although the obstetric complications have been related to the procoagulant properties of antiphospholipid antibodies, pathological studies of human placenta have shown the proinflammatory capacity of antiphospholipid antibodies via the complement system and proinflammatory cytokines. There is no general agreement on which antiphospholipid antibodies profile (laboratory) confers the greatest obstetric risk, but the best candidates are categories I and IIa. Combined treatment with low doses of aspirin and heparin achieves good obstetric and maternal outcomes. In this study, we also review the therapeutic possibilities in refractory cases, although the likelihood of progressing to other autoimmune diseases is low. We briefly comment on incomplete obstetric antiphospholipid syndrome, also known as antiphospholipid antibody-mediated pregnancy morbidity syndrome. PMID:26603476

    2001-01-01

    In patients with an orthostatic intolerance, the hemodynamic response to standing, may identify an abnormality know as postural orthostatic tachycardia syndrome or orthostatic hypotension, that can often be treated without further testing. When the response to standing is normal, tilt-table testing may be useful in making the diagnosis of vasovagal syncope or postural orthostatic tachycardia syndrome and guiding treatment. In evaluating the results of tilt-table testing, an important consideration is the distinction between vasovagal syncope, and the dysautonomic response to tilt characterized by a gradual and progressive decrease in blood pressure that leads to syncope. Current practice patterns suggest that beta blockers, fludrocortisone, and midodrine are commonly used to treat patients with vasovagal syncope. These also suggest that patients with the postural orthostatic tachycardia syndrome, and with the dysautonomic response, are better treated with fludrocortisone and midodrine. PMID:11565347

    Loin pain hematuria syndrome (LPHS), first described in 1967, is a rare pain syndrome, which is not well understood. The syndrome is characterized by severe intermittent or persistent flank pain, either unilateral or bilateral, associated with gross or microscopic hematuria. LPHS is a diagnosis of exclusion as there still is not a consensus of validated diagnostic criteria, though several criteria have been proposed. The wide differential diagnosis would suggest a meticulous yet specific diagnostic work-up depending on the individual clinical features and natural history. Several mechanisms regarding the pathophysiology of LPHS have been proposed but without pinpointing the actual causative etiology, the treatment remains symptomatic. Treatment modalities for LPHS are diverse including simple analgesia, opioid analgesic and kidney autotransplantation. This review article summarizes the current understanding regarding the pathophysiology of LPHS along with the steps required for proper diagnosis and a discussion of the different therapeutic approaches for LPHS.

    Grahame, Rodney

    2009-12-01

    Joint hypermobility syndrome (JHS) was initially defined as the occurrence of musculoskeletal symptoms in the presence of joint laxity and hypermobility in otherwise healthy individuals. It is now perceived as a commonly overlooked, underdiagnosed, multifaceted, and multisystemic heritable disorder of connective tissue (HDCT), which shares many of the phenotypic features of other HDCTs such as Marfan syndrome and Ehlers-Danlos syndrome. Whereas the additional flexibility can confer benefits in terms of mobility and agility, adverse effects of tissue laxity and fragility can give rise to clinical consequences that resonate far beyond the confines of the musculoskeletal system. There is hardly a clinical specialty to be found that is not touched in one way or another by JHS. Over the past decade, it has become evident that of all the complications that may arise in JHS, chronic pain is arguably the most menacing and difficult to treat. PMID:19889283

    Lemierre's syndrome or postanginal septicaemia (necrobacillosis) is caused by an acute oropharyngeal infection with secondary septic thrombophlebitis of the internal jugular vein and frequent metastatic infections. Fusobacterium necrophorum is the most common pathogen isolated from the patients. The interval between the oropharyngeal infection and the onset of the septicaemia is usually short. The most common sites of septic embolisms are the lungs and joints, and other locations can be affected. A high degree of clinical suspicion is needed to diagnose the syndrome. Computed tomography of the neck with contrast is the most useful study to detect internal jugular vein thrombosis. Treatment includes intravenous antibiotic therapy and drainage of septic foci. The role of anticoagulation is controversial. Ligation or excision of the internal jugular vein may be needed in some cases.

    Fat embolism syndrome (FES) was first described in 1862, but its frequency today is still unclear. A diagnosis of FES is often missed because of a subclinical illness or coexisting confusing injuries or disease. Fat embolism syndrome develops most commonly after orthopedic injuries, but it has also been reported after other forms of trauma such as severe burns, liver injury, closed-chest cardiac massage, bone marrow transplantation, and liposuction. Although FES usually presents as a multisystem disorder, the most seriously affected organs are the lung, brain, cardiovascular system, and skin. Fat embolism syndrome is a self-limiting disease and treatment should be mainly supportive. Many drugs have been used to treat FES, but the results are inconclusive. PMID:17186337

    Lemierre’s syndrome is a condition characterized by thrombophlebitis of the internal jugular vein and bacteremia caused by primarily anaerobic organisms, following a recent oropharyngeal infection. This has been an uncommon illness in the era of antibiotic therapy, though it has been reported with increasing frequency in the past 15 years. Lemierre’s syndrome should be suspected in young healthy patients with prolonged symptoms of pharyngitis followed by symptoms of septicemia or pneumonia, or an atypical lateral neck pain. Diagnosis is often confirmed by identification of thrombophlebitis of the internal jugular vein and growth of anaerobic bacteria on blood culture. Treatment involves prolonged antibiotic therapy occasionally combined with anticoagulation. We review the literature and a case of a child with Lemierre’s syndrome. PMID:24152679

    2005-10-01

    Posterior ankle impingement syndrome is a clinical disorder characterized by posterior ankle pain that occurs in forced plantar flexion. The pain may be acute as a result of trauma or chronic from repetitive stress. Pathology of the os trigonum-talar process is the most common cause of this syndrome, but it also may result from flexor hallucis longus tenosynovitis, ankle osteochondritis, subtalar joint disease, and fracture. Patients usually report chronic or recurrent posterior ankle pain caused or exacerbated by forced plantar flexion or push-off maneuvers, such as may occur during dancing, kicking, or downhill running. Diagnosis of posterior ankle impingement syndrome is based primarily on clinical history and physical examination. Radiography, scintigraphy, computed tomography, and magnetic resonance imaging depict associated bone and soft-tissue abnormalities. Symptoms typically improve with nonsurgical management, but surgery may be required in refractory cases. PMID:16224109

    Recent progress in the understanding of the paraneoplastic neurologic syndromes has included further deliniation of the clinical syndromes and their treatment, attempts at standardization of the diagnostic nomenclature, investigations of pathogenetic mechanisms, and molecular characterization of the paraneoplastic antigens with implications as to their biologic relevance. Despite more than 30 years of investigation, the pathogenesis of these presumably autoimmune conditions remains unclear. Furthermore, no effective therapy has been identified for these conditions, with the possible exception of the opsoclonus-myoclonus ataxia and Lambert-Eaton myasthenic syndromes. Future investigations must focus on the disrupted genetic regulatory events involved in generation and propagation of the autoimmune response, antigen presentation and processing; target cell destruction, and consideration of alternative pathologic causes. Effective management strategies are most likely to develop from a better understanding of the disease pathogenesis, the development of animal model systems, and a creative look beyond the usual therapies employed in autoimmune conditions.

    Parsonage-Turner Syndrome (PTS), also referred to as idiopathic brachial plexopathy or neuralgic amyotrophy, is a rare disorder consisting of a complex constellation of symptoms with abrupt onset of shoulder pain, usually unilaterally, followed by progressive neurologic deficits of motor weakness, dysesthesias, and numbness. Although the etiology of the syndrome is unclear, it is reported in various clinical situations, including postoperatively, postinfectious, posttraumatic, and postvaccination. The identification of the syndrome in the postoperative patient remains a challenge as symptoms may easily be attributed to sequelae of surgical positioning, postoperative recovery, or postanesthetic block pain. The purpose of this review is to bring forth salient, identifiable factors which may assist the surgical clinician in identifying the condition sooner. An early and proper diagnosis affords the opportunity to treat the patient accordingly and to the satisfaction of both surgeon and patient. PMID:21886536

    Ko, Jung Min

    2016-05-01

    Craniosynostosis is defined as the premature fusion of one or more of the cranial sutures. It leads not only to secondary distortion of skull shape but to various complications including neurologic, ophthalmic and respiratory dysfunction. Craniosynostosis is very heterogeneous in terms of its causes, presentation, and management. Both environmental factors and genetic factors are associated with development of craniosynostosis. Nonsyndromic craniosynostosis accounts for more than 70% of all cases. Syndromic craniosynostosis with a certain genetic cause is more likely to involve multiple sutures or bilateral coronal sutures. FGFR2, FGFR3, FGFR1, TWIST1 and EFNB1 genes are major causative genes of genetic syndromes associated with craniosynostosis. Although most of syndromic craniosynostosis show autosomal dominant inheritance, approximately half of patients are de novo cases. Apert syndrome, Pfeiffer syndrome, Crouzon syndrome, and Antley-Bixler syndrome are related to mutations in FGFR family (especially in FGFR2), and mutations in FGFRs can be overlapped between different syndromes. Saethre-Chotzen syndrome, Muenke syndrome, and craniofrontonasal syndrome are representative disorders showing isolated coronal suture involvement. Compared to the other types of craniosynostosis, single gene mutations can be more frequently detected, in one-third of coronal synostosis patients. Molecular diagnosis can be helpful to provide adequate genetic counseling and guidance for patients with syndromic craniosynostosis. PMID:27226847

  6. Genetic Syndromes Associated with Craniosynostosis

    PubMed Central

    2016-01-01

    Craniosynostosis is defined as the premature fusion of one or more of the cranial sutures. It leads not only to secondary distortion of skull shape but to various complications including neurologic, ophthalmic and respiratory dysfunction. Craniosynostosis is very heterogeneous in terms of its causes, presentation, and management. Both environmental factors and genetic factors are associated with development of craniosynostosis. Nonsyndromic craniosynostosis accounts for more than 70% of all cases. Syndromic craniosynostosis with a certain genetic cause is more likely to involve multiple sutures or bilateral coronal sutures. FGFR2, FGFR3, FGFR1, TWIST1 and EFNB1 genes are major causative genes of genetic syndromes associated with craniosynostosis. Although most of syndromic craniosynostosis show autosomal dominant inheritance, approximately half of patients are de novo cases. Apert syndrome, Pfeiffer syndrome, Crouzon syndrome, and Antley-Bixler syndrome are related to mutations in FGFR family (especially in FGFR2), and mutations in FGFRs can be overlapped between different syndromes. Saethre-Chotzen syndrome, Muenke syndrome, and craniofrontonasal syndrome are representative disorders showing isolated coronal suture involvement. Compared to the other types of craniosynostosis, single gene mutations can be more frequently detected, in one-third of coronal synostosis patients.

  9. Postural Orthostatic Tachycardia Syndrome

    PubMed Central

    2014-01-01

    The postural orthostatic tachycardia syndrome is a disease characterized by excessively increased heart rate during orthostatic challenge associated with symptoms of orthostatic intolerance including dizziness, exercise intolerance, headache, fatigue, memory problems, nausea, blurred vision, pallor, and sweating, which improve with recumbence. Postural orthostatic tachycardia syndrome patients may present with a multitude of additional symptoms that are attributable to vascular vasoconstriction. Observed signs and symptoms in a patient with postural orthostatic tachycardia syndrome include tachycardia at rest, exaggerated heart rate increase with upright position and exercise, crushing chest pain, tremor, syncope, loss of vision, confusion, migraines, fatigue, heat intolerance, parasthesia, dysesthesia, allodynia, altered traditional senses, and thermoregulatory abnormalities. There are a number of possible dermatological manifestations of postural orthostatic tachycardia syndrome easily explained by its recently discovered pathophysiology. The author reports the case of a 22-year-old woman with moderate-to-severe postural orthostatic tachycardia syndrome with numerous dermatological manifestations attributable to the disease process. The cutaneous manifestations observed in this patient are diverse and most noticeable during postural orthostatic tachycardia syndrome flares. The most distinct are evanescent, hyperemic, sharply demarcated, irregular patches on the chest and neck area that resolve upon diascopy. This distinct “evanescent hyperemia” disappears spontaneously after seconds to minutes and reappears unexpectedly. Other observed dermatological manifestations of this systemic disease include Raynaud’s phenomenon, koilonychia, onychodystrophy, madarosis, dysesthesia, allodynia, telogen effluvium, increased capillary refill time, and livedo reticularis. The treatment of this disease poses a great challenge. The author reports the unprecedented use of an

    Marfan syndrome (MFS) is a pleiotropic connective tissue disease inherited as an autosomal dominant trait, due to mutations in the FBN1 gene encoding fibrillin 1. It is an important protein of the extracellular matrix that contributes to the final structure of a microfibril. Few cases displaying an autosomal recessive transmission are reported in the world. The FBN1 gene, which is made of 66 exons, is located on chromosome 15q21.1. This review, after an introduction on the clinical manifestations that leads to the diagnosis of MFS, focuses on cardiovascular manifestations, pharmacological and surgical therapies of thoracic aortic aneurysm and/or dissection (TAAD), mechanisms underlying the progression of aneurysm or of acute dissection, and biomarkers associated with progression of TAADs. A Dutch group compared treatment with losartan, an angiotensin II receptor-1 blocker, vs no other additional treatment (COMPARE clinical trial). They observed that losartan reduces the aortic dilatation rate in patients with Marfan syndrome. Later on, they also reported that losartan exerts a beneficial effect on patients with Marfan syndrome carrying an FBN1 mutation that causes haploinsufficiency (quantitative mutation), while it has no significant effect on patients displaying dominant negative (qualitative) mutations. Moreover, a French group in a 3-year trial compared the administration of losartan vs placebo in patients with Marfan syndrome under treatment with beta-receptor blockers. They observed that losartan decreases blood pressure but has no effect on aortic diameter progression. Thus, beta-receptor blockers remain the gold standard therapy in patients with Marfan syndrome. Three potential biochemical markers are mentioned in this review: total homocysteine, serum transforming growth factor beta, and lysyl oxidase. Moreover, markers of oxidative stress measured in plasma, previously correlated with clinical features of Marfan syndrome, may be explored as potential

    Parsonage-Turner syndrome (PTS) is a rare disorder typically characterized by an abrupt onset of upper extremity pain followed by progressive neurologic deficits, including weakness, atrophy, and occasionally sensory abnormalities. The exact cause and pathophysiology of PTS are complex and incompletely understood. Autoimmune, genetic, infectious, and mechanical processes have all been implicated. No specific treatments have been proven to reduce neurologic impairment or improve the prognosis of PTS. Most patients with PTS are treated with a multidisciplinary approach that includes both physical therapy and pharmacologic treatment, often with multiple agents. Further research is needed.

    Obesity hypoventilation syndrome is a respiratory consequence of morbid obesity that is characterized by alveolar hypoventilation during sleep and wakefulness. The disorder involves a complex interaction between impaired respiratory mechanics, ventilatory drive and sleep-disordered breathing. Early diagnosis and treatment is important, because delay in treatment is associated with significant mortality and morbidity. Available treatment options include non-invasive positive airway pressure (PAP) therapies and weight loss. There is limited long-term data regarding the effectiveness of such therapies. This review outlines the current concepts of clinical presentation, diagnostic and management strategies to help identify and treat patients with obesity-hypoventilation syndromes. PMID:26029497

    Pulmonary alveolar proteinosis (PAP) is a rare syndrome characterized by the accumulation of surfactant in alveoli and terminal airways resulting in respiratory failure. PAP comprises part of a spectrum of disorders of surfactant homeostasis (clearance and production). The surfactant production disorders are caused by mutations in genes required for normal surfactant production. The PAP syndrome is identified based on history, radiologic, and bronchoalveolar lavage and/or histopathologic findings. The diagnosis of PAP-causing diseases in secondary PAP requires further studies. Whole-lung lavage is the current standard therapy and promising new pharmacologic therapies are in development.

Although some patients have mild symptoms and may even be managed in the outpatient setting, others have more severe symptoms or a history of adverse outcomes that requires close inpatient supervision and benzodiazepine therapy. Many patients with AWS have multiple management issues (withdrawal symptoms, delirium tremens, the Wernicke-Korsakoff syndrome, seizures, depression, polysubstance abuse, electrolyte disturbances and liver disease), which requires a coordinated, multidisciplinary approach. Although AWS may be complex, careful evaluation and available treatments should ensure safe detoxification for most patients. PMID:17986499

    Familial atypical multiple mole melanoma (FAMMM) syndrome is an autosomal dominant disorder with variable incomplete penetrance of the clinical phenotypes. Pathogenesis of this syndrome has not been fully investigated. Across multiple studies, germline mutations in the INK4a antioncogene encoding p16 protein were found on average in approximately 40% of the FAMMM syndrome. Patients with the FAMMM syndrome are genetically loaded with an increased risk of developing melanoma and other malignant neoplasms, for example, a pancreatic cancer. Melanoma can develop from numerous atypical moles as well as de novo. A proper diagnosis of the syndrome and early application of prophylactics decreases the risk of neoplastic transformation of melanocytes. PMID:14871223

    To date, there have been a very limited number of case reports on combined Alport syndrome (AS) and Klinefelter syndrome (KS). We herein describe the case of a 9-month-old boy diagnosed with concomitant AS and KS. KS was detected on chromosomal analysis of the amniotic fluid, and hematuria/proteinuria was identified in urinary screening at 6 months of age. Renal biopsy indicated AS, with complete deficit of the α5 chain of type IV collagen in the glomerular basement membranes. On genetic analysis for AS, de novo homozygote mutation (c.3605-2a > c) was seen in the gene encoding α5 chain of type IV collagen (COL4A5) on the X chromosomes of maternal origin. This is the first case report of combined AS and KS diagnosed during infancy, and it indicates the need to consider the concurrent existence of these two disorders in infants with urine abnormalities, even in the absence of a family history.

    Objective. Drugs can induce almost the entire spectrum of hematologic disorders, affecting white cells, red cells, platelets, and the coagulation system. This paper aims to emphasize the broad range of drug-induced hematological syndromes and to highlight some of the newer drugs and syndromes. Methods. Medline literature on drug-induced hematologic syndromes was reviewed. Most reports and reviews focus on individual drugs or cytopenias. Results. Drug-induced syndromes include hemolytic anemias, methemoglobinemia, red cell aplasia, sideroblastic anemia, megaloblastic anemia, polycythemia, aplastic anemia, leukocytosis, neutropenia, eosinophilia, immune thrombocytopenia, microangiopathic syndromes, hypercoagulability, hypoprothrombinemia, circulating anticoagulants, myelodysplasia, and acute leukemia. Some of the classic drugs known to cause hematologic abnormalities have been replaced by newer drugs, including biologics, accompanied by their own syndromes and unintended side effects. Conclusions. Drugs can induce toxicities spanning many hematologic syndromes, mediated by a variety of mechanisms. Physicians need to be alert to the potential for iatrogenic drug-induced hematologic complications. PMID:19960059

    Hunter's syndrome is one of a group of heritable metabolic disorders caused by decreased activity of one or more of the lysosomal enzymes responsible for mucopolysaccharide catabolism, resulting in excessive deposition of mucopolysaccharides in skeletal and soft tissues. Pulmonary conditions, such as airway obstruction, sleep apnea syndrome, atalectasis, recurrent pneumonia and difficult endotracheal intubation are known to be associated with these rare disorders and have been reported. We report the findings at laryngotracheobronchoscopy of a patient with Hunter's syndrome with airway symptoms and, supported by analysis of previously reported cases of airway problems associated with the syndrome, suggest that tracheobronchomalacia with classifiable major airway collapse (MAC) may be the pathological correlate for this clinical picture. The endoscopic technique and characteristic findings of tracheobronchomalacia/MAC are discussed, as well as the natural history and pathophysiology of this condition, which is characterized by weakness of the tracheal wall due to softening of the supporting cartilage and hypotonia of the myoelastic elements with reduction in the tracheal lumen.

  20. The Tie retraction syndrome.

    2012-12-01

    Tissue retraction is implicated in the pathogenesis of various ophthalmic disorders. Here we describe the clinical characteristics, epidemiology and pathophysiology of a form of retraction syndrome which - to the best of our knowledge - has not been reported in the ophthalmic literature so far. We have termed this condition - consisting of a slowly progressive pseudovertical shortening of tie length due to a horizontal extension of girth length - the "Tie retraction syndrome" (TRS). Other pathognomonic features include an increased tie tip to belt buckle distance and a prolapse of the subumbilical fat pad (SUFP). The syndrome has a clear male to female preponderance and shows an increasing incidence with age and income before tax. Based on a newly proposed grading scheme we discuss and illustrate the diagnosis as well as the medical and surgical management options of this abundant, but often undiagnosed condition. The authors have no explanation for the apparent lack of awareness for this widely preponderant syndrome and its severe cosmetically disfiguring potential. We thus would like to invite all fellow colleagues with expertise in the field to comment or present their views. PMID:23088329

  5. The Schnitzler syndrome

    PubMed Central

    2010-01-01

    The Schnitzler syndrome is a rare and underdiagnosed entity which is considered today as being a paradigm of an acquired/late onset auto-inflammatory disease. It associates a chronic urticarial skin rash, corresponding from the clinico-pathological viewpoint to a neutrophilic urticarial dermatosis, a monoclonal IgM component and at least 2 of the following signs: fever, joint and/or bone pain, enlarged lymph nodes, spleen and/or liver, increased ESR, increased neutrophil count, abnormal bone imaging findings. It is a chronic disease with only one known case of spontaneous remission. Except of the severe alteration of quality of life related mainly to the rash, fever and pain, complications include severe inflammatory anemia and AA amyloidosis. About 20% of patients will develop a lymphoproliferative disorder, mainly Waldenström disease and lymphoma, a percentage close to other patients with IgM MGUS. It was exceedingly difficult to treat patients with this syndrome until the IL-1 receptor antagonist anakinra became available. Anakinra allows a complete control of all signs within hours after the first injection, but patients need continuous treatment with daily injections. In many aspects, the Schnitzler syndrome resembles the genetically determined auto-inflammatory syndromes involving activating mutations of the NLRP3 inflammasome. This latter point and its consequences will be addressed. PMID:21143856

    Systemic autoinflammatory diseases are a group of hereditary and non-hereditary diseases of the innate immune system, characterized by inflammation with no apparent cause, recurrence at irregular intervals and manifestation on the skin, mucous membranes, joints, bone, gastrointestinal tract, blood vessels and the central nervous system (CNS). Amyloidosis and other possibly severe long-term complications are important. Advances in genetics and molecular biology have improved understanding of the pathogenesis of these diseases, including familial Mediterranean fever, mevalonate kinase deficiency syndrome, tumor necrosis factor receptor-associated periodic syndrome, cryopyrin-associated periodic syndrome and improved others. The vast majority of these diseases are based on activation of the interleukin-1 (IL-1) pathway, so that inhibition of IL-1 provides a therapeutic option. Other syndromes are characterized by a granulomatous inflammation. Newer autoinflammatory diseases, such as chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature (CANDLE) and stimulator of interferon genes (STING)-associated vasculopathy with onset in infancy (SAVI) are, however, driven by interferons.

  11. The Syndrome of Catatonia

    Catatonia is a psychomotor syndrome which has historically been associated with schizophrenia. Many clinicians have thought that the prevalence of this condition has been decreasing over the past few decades. This review reminds clinicians that catatonia is not exclusively associated with schizophrenia, and is still common in clinical practice. Many cases are related to affective disorders or are of an idiopathic nature. The illusion of reduced prevalence has been due to evolving diagnostic systems that failed to capture catatonic syndromes. This systemic error has remained unchallenged, and potentiated by the failure to perform adequate neurological evaluations and catatonia screening exams on psychiatric patients. We find that current data supports catatonic syndromes are still common, often severe and of modern clinical importance. Effective treatment is relatively easy and can greatly reduce organ failure associated with prolonged psychomotor symptoms. Prompt identification and treatment can produce a robust improvement in most cases. The ongoing prevalence of this syndrome requires that psychiatrists recognize catatonia and its presentations, the range of associated etiologies, and the import of timely treatment. PMID:26690229

    Munchausen syndrome and necrophilia are uncommon disorders which do not appear to be related. It is suggested, however, that both of them center on "return to the womb" fantasies and may represent variants of each other. Specifically, the Munchausen patient's symptom triad (factitious illness, peregrination, pseudologia fantastica) is seen to reflect a wish for death and reunion with the maternal object.

    1982-01-01

    The description of the thalamic syndrome by J. Dejerine and G. Roussy in 1906 was a consecration of the clinicopathologic method, announcing the end of discussions relative to the role of the thalamus as a sensorial relay center, discussions opposing B. Luys to Türk and to Charcot and which animated the end of the 19th century. Since then, the thalamic syndrome has not ceased to arouse the attention of neurologists, who have developed four major themes: the specificity of the thalamic hemianesthesia; the mechanism of the central pain; the semiologic value and physiopathology of the abnormal movements; and finally the pupillary and vasomotor disorders. Exploration of each of these topics led to a definition of neurologic semiology and to the development of neurophysiology during the second half of the XXth century. By reviewing this the confrontation between different men and schools appears behind the opposition of ideas. The revision of the thalamic syndrome ceased when the discovery of the non-specific functions of the thalamus opened the way to new concepts. Dejerine-Roussy's syndrome expresses the semiology of the relay nuclei. For the last thirty years, experience has accumulated on the semiology of lesions affecting the nuclei of convergence. Neuropsychology of thalamic lesions has demonstrated the regulatory role performed by the thalamus within each hemisphere and in the relative activation of each hemisphere. But this is another story.
