Abstract
Importance: Amyotrophic lateral sclerosis (ALS) is a devastating adult-onset neurodegenerative disorder with a poor prognosis and a median survival of 3 years. However, a significant proportion of patients survive more than 10 years from symptom onset.
Objective: To identify gene variants influencing survival in ALS.
Design, Setting, and Participants: This genome-wide association study (GWAS) analyzed survival in data sets from several European countries and the United States that were collected by the Italian Consortium for the Genetics of ALS and the International Consortium on Amyotrophic Lateral Sclerosis Genetics. The study population included 4256 patients with ALS (3125 [73.4%] deceased) with genotype data extended to 7 174 392 variants by imputation analysis. Samples of DNA were collected from January 1, 1993, to December 31, 2009, and analyzed from March 1, 2014, to February 28, 2015.
Main Outcomes and Measures: Cox proportional hazards regression under an additive model with adjustment for age at onset, sex, and the first 4 principal components of ancestry, followed by meta-analysis, were used to analyze data. Survival distributions for the most associated genetic variants were assessed by Kaplan-Meier analysis.
Results: Among the 4256 patients included in the analysis (2589 male [60.8%] and 1667 female [39.2%]; mean [SD] age at onset, 59 [12] years), the following 2 novel loci were significantly associated with ALS survival: at 10q23 (rs139550538; P = 1.87 × 10-9) and in the CAMTA1 gene at 1p36 (rs2412208, P = 3.53 × 10-8). At locus 10q23, the adjusted hazard ratio for patients with the rs139550538 AA or AT genotype was 1.61 (95% CI, 1.38-1.89; P = 1.87 × 10-9), corresponding to an 8-month reduction in survival compared with TT carriers. For rs2412208CAMTA1, the adjusted hazard ratio for patients with the GG or GT genotype was 1.17 (95% CI, 1.11-1.24; P = 3.53 × 10-8), corresponding to a 4-month reduction in survival compared with TT carriers.
Conclusions and Relevance: This GWAS robustly identified 2 loci at genome-wide levels of significance that influence survival in patients with ALS. Because ALS is a rare disease and prevention is not feasible, treatment that modifies survival is the most realistic strategy. Therefore, identification of modifier genes that might influence ALS survival could improve the understanding of the biology of the disease and suggest biological targets for pharmaceutical intervention. In addition, genetic risk scores for survival could be used as an adjunct to clinical trials to account for the genetic contribution to survival.

How can clinical ethics guide the management of comorbidities in the child with Rett syndrome?

J Paediatr Child Health. 2016 May 31;

Authors: Downs J, Forbes D, Johnson M, Leonard H

Abstract
Rett syndrome is a rare disorder caused by a mutation in the MECP2 gene. Those affected generally have severe functional impairments, and medical comorbidities such as scoliosis and poor growth are common. There is a paucity of information on the natural history of many rare disorders and an even greater deficit of evidence to guide best practice. The population-based and longitudinal Australian Rett Syndrome Database established in 1993 has supported investigations of the natural history of Rett syndrome and effectiveness of treatments. This paper reviews the disorder Rett syndrome and evidence for the management of scoliosis and poor growth within a clinical ethics framework. Compared with conservative management, we have shown that spinal fusion is associated with reduced mortality and better respiratory health. We have also shown that gastrostomy insertion is associated with subsequent weight gain. Family counselling for both procedures necessarily must include family perspectives and careful clinical attention to their needs and wishes. Vignettes describing family decision-making and experiences are presented to illustrate the principals of beneficence and autonomy in determining the best interests of the child and family. A blend of evidence-based practice with a strong clinical ethics framework has capacity to build existing strengths in families and reduce the negative impacts of disability and in so doing, optimise the health and wellbeing of those with Rett syndrome.

Next-generation sequencing for diagnosis of rare diseases in the neonatal intensive care unit.

CMAJ. 2016 May 30;

Authors: Daoud H, Luco SM, Li R, Bareke E, Beaulieu C, Jarinova O, Carson N, Nikkel SM, Graham GE, Richer J, Armour C, Bulman DE, Chakraborty P, Geraghty M, Lines MA, Lacaze-Masmonteil T, Majewski J, Boycott KM, Dyment DA

Abstract
BACKGROUND: Rare diseases often present in the first days and weeks of life and may require complex management in the setting of a neonatal intensive care unit (NICU). Exhaustive consultations and traditional genetic or metabolic investigations are costly and often fail to arrive at a final diagnosis when no recognizable syndrome is suspected. For this pilot project, we assessed the feasibility of next-generation sequencing as a tool to improve the diagnosis of rare diseases in newborns in the NICU.
METHODS: We retrospectively identified and prospectively recruited newborns and infants admitted to the NICU of the Children's Hospital of Eastern Ontario and the Ottawa Hospital, General Campus, who had been referred to the medical genetics or metabolics inpatient consult service and had features suggesting an underlying genetic or metabolic condition. DNA from the newborns and parents was enriched for a panel of clinically relevant genes and sequenced on a MiSeq sequencing platform (Illumina Inc.). The data were interpreted with a standard informatics pipeline and reported to care providers, who assessed the importance of genotype-phenotype correlations.
RESULTS: Of 20 newborns studied, 8 received a diagnosis on the basis of next-generation sequencing (diagnostic rate 40%). The diagnoses were renal tubular dysgenesis, SCN1A-related encephalopathy syndrome, myotubular myopathy, FTO deficiency syndrome, cranioectodermal dysplasia, congenital myasthenic syndrome, autosomal dominant intellectual disability syndrome type 7 and Denys-Drash syndrome.
INTERPRETATION: This pilot study highlighted the potential of next-generation sequencing to deliver molecular diagnoses rapidly with a high success rate. With broader use, this approach has the potential to alter health care delivery in the NICU.

Genotyping of relapsing polychondritis identified novel susceptibility HLA alleles and distinct genetic characteristics from other rheumatic diseases.

Rheumatology (Oxford). 2016 May 30;

Authors: Terao C, Yoshifuji H, Yamano Y, Kojima H, Yurugi K, Miura Y, Maekawa T, Handa H, Ohmura K, Saji H, Mimori T, Matsuda F

Abstract
OBJECTIVE: To uncover the genetic background of relapsing polychondritis (RPC), a rare autoimmune disease with unknown mechanisms characterized by systemic inflammation of the cartilage, to deepen our understanding of the pathophysiology of RPC and show its distinct genetic characteristics from other rheumatic diseases.
METHODS: A total of 102 patients with RPC and 1000 healthy subjects were recruited for a two-staged genetic association study and genotyped for six HLA classical loci. Haplotype association tests were also performed. The associations of amino acid (AA) residues and positions with susceptibility to RPC were analysed. Frequencies of representative susceptibility HLA alleles to other rheumatic diseases in RPC were also analysed.
RESULTS: HLA-DRB1*16:02, HLA-DQB1*05:02 and HLA-B*67:01, which are in linkage disequilibrium with each other, were associated with RPC (P = 1.9 × 10(-6), 1.4 × 10(-5) and 0.00024, respectively). AA residue at position 57 in HLA-DQB1, the most significant position in type I diabetes mellitus, showed the strongest association among AA residues. HLA-DR4, a known susceptibility allele in Germans, showed a trend of susceptibility association without significance (P = 0.067). No associations were observed between the three alleles and clinical phenotypes. Representative susceptibility HLA alleles to RA, SLE, Behçet disease and Takayasu arteritis did not show enrichment in RPC in spite of sufficient statistical power.
CONCLUSIONS: HLA-DRB1*16:02, HLA-DQB1*05:02 and HLA-B*67:01, in linkage disequilibrium with each other, are associated with susceptibility to RPC Importance of HLA-class II loci in RPC susceptibility is suggested. RPC is considered a genetically distinct disease from other rheumatic diseases.

Hajdu-Cheney Syndrome, a Disease Associated with NOTCH2 Mutations.

Curr Osteoporos Rep. 2016 May 30;

Authors: Canalis E, Zanotti S

Abstract
Notch plays an important function in skeletal homeostasis, osteoblastogenesis, and osteoclastogenesis. Hajdu-Cheney syndrome (HCS) is a rare disease associated with mutations in NOTCH2 leading to the translation of a truncated NOTCH2 stable protein. As a consequence, a gain-of-NOTCH2 function is manifested. HCS is inherited as an autosomal dominant disease although sporadic cases exist. HCS is characterized by craniofacial developmental defects, including platybasia and wormian bones, osteoporosis with fractures, and acro-osteolysis. Subjects may suffer severe neurological complications, and HCS presents with cardiovascular defects and polycystic kidneys. An experimental mouse model harboring a HCSNotch2 mutation exhibits osteopenia secondary to enhanced bone resorption suggesting this as a possible mechanism for the skeletal disease. If the same mechanisms were operational in humans, anti-resorptive therapy could correct the bone loss, but not necessarily the acro-osteolysis. In conclusion, HCS is a devastating disease associated with a gain-of-NOTCH2 function resulting in diverse clinical manifestations.

Rapid Identification of Klebsiella pneumoniae by Matrix-Assisted Laser Desorption/Ionization-Time of Flight Mass Spectrometry and Detection of Meropenem Resistance by Flow Cytometric Assay.

J Clin Lab Anal. 2016 May 30;

Authors: Kilic A, Dogan E, Kaya S, Oren S, Tok D, Ardic N, Baysallar M

Abstract
BACKGROUND: The aim of this study was to develop a rapid detection method of carbapenem-resistant Klebsiella pneumoniae (CRKP) strains both MALDI-TOF MS and flow cytometry (FCM).
METHODS: A total of 174 K. pneumoniae strains were included in this study. Molecular characterization of carbapenemase gene was performed by PCR. Bacterial identification was performed by MALDI-TOF-MS. Meropenem susceptibility was tested at the concentrations of breakpoints described by the Clinical and Laboratory Standards Institute (CLSI) guide by FCM.
RESULTS: Sixty-two CRKP were positive for at least one carbapenemase gene. A total of 174 K. pneumoniae isolates obtained from clinically relevant material were correctly identified by Bruker MALDI-TOF MS with log (score) >2.0. These results were 100% concordant with the Phoenix(™) Automated Microbiology System (BD, MD) and conventional identification results. Based on the analysis of the receiver operating characteristic (ROC) curves, the best validity and sensitivity data were obtained with a cut-off value of 18.88% by FCM. The concordance, sensitivity, and specificity for FCM by the selected cut-off values were 99.4%, 98.9%, and 100%, respectively.
CONCLUSIONS: We conclude that reliable results on bacterial identification and meropenem susceptibility test can be obtained within 2 hr combined by MALDI-TOF-MS and FCM.

Appendicular mucinous adenocarcinoma associated with pseudomyxoma peritonei, a rare and difficult imaging diagnosis.

Med Ultrason. 2016 Jun;18(2):257-9

Authors: Chira RI, Nistor-Ciurba CC, Mociran A, Mircea PA

Abstract
Pseudomyxoma peritonei (PMP) is a rare disease, caused by primary mucinous tumors that arise most frequently from appendix, ovary, or pancreas. Usually diagnosis is made by computed tomography, but ultrasonography can be a very useful imagistic method, if this diagnosis is taken into account by the observer. We present a case of a PMP caused by an appendiceal mucinous carcinoma, in a 34-year-old male patient, with family history of malignancies, diagnosed in our department. He was thereafter surgically treated - appendiceal resection, peritoneal lavage - followed by chemotherapy. We underline the importance of ultrasonography, even though at first encounter, the diagnosis of PMP being generally difficult.

Pigment Epithelium-Derived Factor (PEDF) is a Determinant of Stem Cell Fate: Lessons from an Ultra-Rare Disease.

J Dev Biol. 2015 Dec;3(4):112-128

Authors: Sagheer U, Gong J, Chung C

Abstract
PEDF is a secreted glycoprotein that is widely expressed by multiple organs. Numerous functional contributions have been attributed to PEDF with antiangiogenic, antitumor, anti-inflammatory, and neurotrophic properties among the most prominent. The discovery that null mutations in the PEDF gene results in Osteogenesis Imperfecta Type VI, a rare autosomal recessive bone disease characterized by multiple fractures, highlights a critical developmental function for this protein. This ultra-rare orphan disease has provided biological insights into previous studies that noted PEDF's effects on various stem cell populations. In addition to bone development, PEDF modulates resident stem cell populations in the brain, muscle, and eye. Functional effects on human embryonic stem cells have also been demonstrated. An overview of recent advances in our understanding by which PEDF regulates stem cells and their potential clinical applications will be evaluated in this review.

Validation of the Korean Genome Epidemiology Study Risk Score to Predict Incident Hypertension in a Large Nationwide Korean Cohort.

Circ J. 2016 May 25;

Authors: Lim NK, Lee JW, Park HY

Abstract
BACKGROUND: This study aimed to validate the Korean Genome Epidemiology Study (KoGES) risk score to predict the 4-year risk of hypertension (HT) in a large nationwide sample, and compare its discrimination and calibration with the Framingham and blood pressure (BP)-only models.Methods and Results:This study analyzed 69,918 subjects without HT at baseline from the National Sample Cohort in the National Health Insurance Service database. We compared the Framingham, KoGES, and BP-only models for discrimination using area under the receiver-operating characteristic curves (AROC), calibration using goodness-of-fit tests, and reclassification ability using the continuous net reclassification improvement (NRI) and integrated discrimination improvement. Of 69,918 subjects, 18.6% developed HT during the follow-up. AROC was significantly higher for the KoGES (0.733) than for the Framingham (0.729) or BP-only (0.707) model. Recalibrated Framingham model underestimated HT incidence in all deciles (P<0.001). BP-only model overestimated risk in the lower deciles (P<0.001). KoGES model accurately predicted risk in all except the highest decile (χ(2)=14.85, P=0.062). The KoGES model led to a significant improvement in risk reclassification compared with the Framingham and BP-only models (NRI, 0.354; 95% confidence interval [CI], 0.343-0.365 and 0.542; 95% CI, 0.523-0.561, respectively).
CONCLUSIONS: In this validation study, the KoGES model demonstrated better discrimination, calibration, and reclassification ability than either the Framingham or BP-only model. The KoGES model may help identify Korean individuals at high risk for HT.

Primary actinomycosis of breast-A diagnosis on cytology.

Diagn Cytopathol. 2016 May 30;

Authors: Gosavi AV, Anvikar AR, Sulhyan KR, Manek DD

Abstract
Primary actinomycosis of breast is a rare disease with only a few cases reported in the literature. We present a case of a 25-year-old lactating woman with primary actinomycosis of breast which was diagnosed on cytology. The patient presented with lump in left breast with dull aching pain. Fine-needle aspiration cytology smears showed acute suppurative inflammation with presence of fluffy basophilic colonies on Hematoxylin and Eosin staining and branched, Gram positive filamentous bacilli on Gram staining. The bacilli were non-acid fast with 1% Zeihl Neelsen stain. A diagnosis of actinomycosis was suggested on cytology. Histopathological examination revealed an abscess with few Gram positive basophilic granules surrounded by eosinophilic Splendore-Hoeppli material thus confirming the diagnosis of actinomycosis. Meticulous search for microorganisms with the aid of special stains should be done on cytology smears before labeling an inflammatory lesion as nonspecific. Diagn.

Association of first-trimester angiogenic factors with placental histological findings in late-onset preeclampsia.

Placenta. 2016 Jun;42:44-50

Authors: Triunfo S, Crovetto F, Crispi F, Rodriguez-Sureda V, Dominguez C, Nadal A, Peguero A, Gratacos E, Figueras F

Abstract
OBJECTIVE: To explore in women with late-onset preeclampsia (PE) the association between maternal levels of angiogenic/antiangiogenic factors in the first trimester of pregnancy and histological findings attributable to placental underperfusion (PUP).
METHODS: A nested case-control cohort study was conducted in 73 women with pregnancies complicated by late-onset PE (>34 weeks at delivery) matched with controls. First trimester uterine artery Doppler (UtA); maternal levels of placental growth factor (PlGF) and soluble fms-like tyrosine kinase-1 (sFlt-1) were retrieved. Placentas were histologically evaluated using a hierarchical and standardized classification system. One-way ANOVA with linear polynomial contrast or linear-by-linear association test was performed to test the hypothesis of a linear association across study groups (controls, PE without PUP and PE with PUP).
RESULTS: In 54 (74%) placentas, 89 placental histological findings qualifying for PUP were found. Across study groups, significant values were observed in maternal levels of decreased PlGF (MoM values: 1.53, 1.41 and 1.37; p < 0.001), increased sFlt-1 (MoM values: 3.11, 3.11 and 3.22; p = 0.002), increased sFlt-1/PlGF ratio (MoM values: 2.3, 2.3 and 2.44; p < 0.001), abnormal UtA Doppler (MoM values: 1, 1.26 and 1.32; p < 0.001), and worse perinatal outcomes in terms of gestational age at delivery, cesarean section for not reassuring fetal status, birth weight and neonatal acidosis.
DISCUSSION: In late-onset PE an imbalance of circulating angiogenic and anti-angiogenic factors already present at 8-10 weeks of pregnancy was associated with histological findings reflecting placental insufficiency. An early first trimester screening by angiogenic factors might help to identify patients with placental involvement among late-onset PE cases.
CONCLUSION: In late-onset preeclampsia, first-trimester uterine Doppler and circulating levels of angiogenic/antiangiogenic factors are associated with placental underperfusion.

Am J Case Rep. 2016;17:360-370

Authors: Abdellateef EE, Abdelhai AR, Gawish HH, Abdulmonaem GA, Abdelbary EH, Ahmed AI

Abstract
BACKGROUND Erdheim-Chester disease is a rare non-Langerhans-cell histiocytosis of unknown etiology with multi-organ involvement. CASE REPORT A 19-year-old woman presented with orthopnea, severe fatigue, bilateral exophthalmos, and gradual loss of vision. She had anemia and mild leucocytosis related to chronic illness. Marked left side pleural effusion and massive pericardial effusion with bilateral hydronephrosis were detected by plain X-ray, echocardiography, and computed tomography, respectively. Retro-orbital tissue and bone marrow biopsy revealed histiocytic infiltration, which was CD68-positive and CD1a-negative. CONCLUSIONS This report describes the first case presentation of Erdheim-Chester disease in our country. This case report may advance our understanding of an orphan disease. Our patient's young age and stable clinical status may allow long-term follow-up of treatment results.

Characteristics of 419 patients with acquired middle ear cholesteatoma.

Braz J Otorhinolaryngol. 2016 May 3;

Authors: Rosito LP, da Silva MN, Selaimen FA, Jung YP, Pauletti MG, Jung LP, Freitas LA, da Costa SS

Abstract
INTRODUCTION: Cholesteatoma is a destructive lesion that can result in life-threatening complications. Typically, it presents with hypoacusis and continuous otorrhea as symptoms. Because it is a rare disease, there are few studies in Brazil describing the characteristics of patients with the disease.
OBJECTIVE: This study aimed to determine the prevalence of cholesteatoma in patients with chronic otitis media and describe clinical, audiological and surgical characteristics of patients with acquired middle ear cholesteatoma treated at a referral hospital in the public health system.
METHODS: Cross-sectional and prospective cohort study, including 1710 patients with chronic otitis media, treated between August 2000 and June 2015, without prior surgery. Detailed clinical history, videotoscopy, and audiometry were performed, in addition to review of medical records to search for surgical data. Cholesteatomas were classified according to their route of formation.
RESULTS: Of the patients with chronic otitis media, 419 (24.5%) had cholesteatoma; mean age of 34.49 years; 53.5% female and 63.8% adults. Bilateral cholesteatoma was observed in 17.1%. Anterior epitympanic cholesteatoma corresponded to 1.9%; posterior epitympanic, 32.9%; posterior mesotympanic, 33.7%; two routes, 14.8%; and indeterminate, 16.7%. The mean air-bone gap was 29.84dB and did not differ between routes of formation. There were no correlations between gap size and patient age or duration of symptoms. Of the surgical cases, 16.8% underwent closed tympanomastoidectomy and 75.2% open tympanomastoidectomy.
CONCLUSION: The prevalence of cholesteatoma in patients with chronic otitis media was 24.5% and it was more common in adults than in children. Posterior mesotympanic cholesteatoma was more frequent, with no difference in mean air-bone gap between the different routes of formation. In patients undergoing surgery, open tympanomastoidectomy was the procedure most frequently chosen.
