Djeho, the Egyptian God's dancer with dwarfism from the thirtieth dynasty.

This manuscript presents some artistic and medical considerations about a representation of an individual with apparent dwarfism. He was found in Saqqara by the British Egyptologist James Edward Quibell, in 1910/11. The naked figure of this individual, Djeho, is carved in profile on the lid of his sarcophagus. He has a height of 120 cm and has characteristic clinical features suggesting achondroplasia.

Pulmonary alveolar capillary dysplasia in infants: A rare and deadly missed diagnosis.

The pulmonary alveolocapillary dysplasia (ACD) with pulmonary vein misalignment (PVM) is a rare condition characterized by a congenital anomaly of the development of the pulmonary parenchyma. We present a case of an 8-month-old infant who died quickly from acute respiratory failure complicating an unknown ACD. We also describe its epidemiological characteristics in infants and we discuss the diagnosis's difficulties. In this case, a pulmonary arterial hypertension was decompensated by an infection. A medico-legal autopsy was performed. As for the Histological examination, it showed the features of ACD/PVM.

The role of AIP variants in pituitary adenomas and concomitant thyroid carcinomas in the Netherlands: a nationwide pathology registry (PALGA) study.

PURPOSE: Germline mutations in the aryl-hydrocarbon receptor interacting protein (AIP) have been identified often in the setting of familial isolated pituitary adenoma (FIPA). To date there is no strong evidence linking germline AIP mutations to other neoplasms apart from the pituitary. Our primary objective was to investigate the prevalence of AIP gene mutations and mutations in genes that have been associated with neuroendocrine tumors in series of tumors from patients presenting with both pituitary adenomas and differentiated thyroid carcinomas (DTCs). METHODS: Pathology samples were retrieved from all pituitary adenomas in patients with concomitant DTCs, including one with a known germline AIP variant. Subsequently, two additional patients with known germline AIP variants were included, of which one presented only with a follicular thyroid carcinoma (FTC). RESULTS: In total, 17 patients (14 DTCs and 15 pituitary adenomas) were investigated by targeted next generation sequencing (NGS). The pituitary tumor samples revealed no mutations, while among the thyroid tumor samples BRAF (6/14, 42.9%) was the most frequently mutated gene, followed by NRAS (3/11, 27.3%). In one AIP-mutated FIPA kindred, the AIP-variant c.853C>T; p.Q285* was confirmed in the FTC specimen, including evidence of loss of heterozygosity (LOH) at the AIP locus in the tumor DNA. CONCLUSION: Although most observed variants in pituitary adenomas and DTCs were similar to those of sporadic DTCs, we confirmed in one AIP mutation-positive case the AIP-variant and LOH at this locus in an FTC specimen, which raises the potential role of the AIP mutation as a rare initiating event.

Acromegaly in the setting of Tatton-Brown-Rahman Syndrome.

PURPOSE: Tatton-Brown-Rahman syndrome (TBRS) is a newly defined genetic entity characterized by overgrowth and intellectual disability, resulting from germline mutations in the gene encoding DNA methyltransferase 3 alpha (DNMT3A). Affected individuals with benign and malignant tumors have been reported; to our knowledge pituitary adenomas (and other tumors identified in our patient) have not yet been described in this syndrome. CASE: We report the case of a 34-year-old woman with TBRS who developed a GH-secreting pituitary macroadenoma and other benign tumors and cystic lesions involving diverse organ systems. Whole-exome sequencing revealed a heterozygous, likely pathogenic variant (c.700_709 del10, p. Gly234ArgfsX79) in exon7 of DNMT3A, and a heterozygous variant of uncertain significance (c.25 C>T, p.Arg9Trp) in exon 1 of the gene encoding aryl hydrocarbon receptor-interacting protein (AIP). The patient failed somatostatin analog treatment, and underwent surgery. The tumor retained AIP expression, and analysis of tumor DNA indicated the presence of both AIP alleles, consistent with no loss of heterozygosity. These findings suggest that the AIP variant was not the primary driver of pituitary adenoma development. CONCLUSION: Our case suggests that TBRS might be associated with pituitary adenoma and a broader spectrum of tumors than previously thought, making long-term follow up of these patients crucial to identify tumors early, and to elucidate the clinical spectrum of the disorder for optimization of management.

Metastatic Solitary Fibrous Tumour of the Kidney Presenting more than a Decade Later with Pulmonary Disease

Introduction Solitary fibrous tumours are rare mesenchymal tumours that most commonly originate from the visceral pleura. Extra-thoracic primary sites including; head and neck, soft tissue, retroperitoneum and the urological tract, are associated with late recurrence. Case We present a case of metastatic pulmonary Solitary Fibrous Tumour presenting 11 years post resection of renal primary Solitary Fibrous Tumour. The patient underwent apical segmentectomy of the right lower lobe extending to wedge excision of right upper lobe due to fissure involvement with lymphadenectomy. The patient was discharged day 12 post surgery. Discussion Robust guidance regarding long-term management of solitary fibrous tumours is lacking. Salvage resection offers favourable long-term prognosis. This case demonstrates the importance of long-term surveillance.

Congenital Atrial Haemangioma

Introduction Primary cardiac tumours are rare. We report the first known case of congenital cardiac haemangioma in Ireland. Case A neonate presented with symptoms arising from a congenital atrial haemangioma on day three of life. The mass was successfully excised via median sternotomy and bicaval cannulation for cardiopulmonary bypass. The patient was discharged day ten postoperatively and remained well at one year follow-up. Discussion The degree of debulking surgery required varies depending on tumour type. This report serves to aid clinicians in accurately suspecting, investigating and diagnosing patients with cardiac tumours.

A Comparison of Inpatient and Outpatient-Based Chemotherapy Regimens for the Treatment of Acute Myeloid Leukaemia In The Elderly.

INTRODUCTION: Acute myeloid leukaemia (AML) is an aggressive haematological malignancy which is more common in the elderly and has a poor 5-year survival. There are no established beneficial interventions to treat AML in elderly patients. It is unclear whether outpatient delivery of palliative chemotherapies could reduce the burden of disease and hospitalisation for this group. AIMS: To compare overall survival, response to treatment and supportive care needs between inpatient and outpatient-based treatments for AML in elderly patients. MATERIALS & METHODS: We undertook a retrospective cohort study in the Haematology Department at Belfast City Hospital comparing overall survival (OS), treatment responses and supportive care needs between inpatient and outpatient treatments for AML in elderly patients. Consecutive entrants to outpatient and inpatient based clinical trials between February 2013 and January 2017 were included. Case notes, chemotherapy charts, clinic letters, blood bank and electronic care records were analysed. RESULTS: OS and rates of CR (complete remission), CRi (CR with incomplete count recovery) and PR (partial response) was not significantly different between inpatient and outpatient regimens with a median OS of 201 vs. 124 days, respectively. No response was observed in 35% of patients in the inpatient group compared with 65% of the outpatient group, however this did not reach significance. Of patients who achieved CR/CRi in the outpatient group, 75% relapsed at a median of 271 days, compared with 60% of the inpatient group at a median of 209 days. At least one grade 3-4 toxicity was experienced by 90% and 83.3% of inpatient and outpatient groups, respectively. There was no difference in six common grade 3-4 toxicities. Patients on the outpatient regimen spent fewer days in hospital but had a median packed red cell use of more than twice that of the inpatient group. No difference was noted in infections, days on antibiotics or platelet use. DISCUSSION: Our data suggests that outpatient chemotherapy is safe and can reduce hospitalisation for elderly patients with AML, without a decline in OS or response rates. These results provide an important rationale to test the comparative efficacy of outpatient chemotherapy. Chemotherapy related toxicities remain a significant source of morbidity in this population and highlight the need to develop novel, targeted therapies for this age group.

Patient eligibility for hematopoietic stem cell transplantation: a review of patient-associated variables.

Assessing patient eligibility for hematopoietic stem cell transplantation (HSCT) remains a complex, multifaceted challenge. Among these challenges, the paucity of comprehensive clinical data to guide decision making remains problematic coupled with unclear trade-offs between patient, disease and local HSCT center factors. Moreover, it is unclear that the modification of poor patient characteristics will improve post-HSCT outcomes. However, the use of Comorbidity Indices and Comprehensive Geriatric Assessments helps meet this challenge, but may be limited by overlapping patient characteristics. The increasing consideration for pre-HSCT psychosocial assessments and interventions remains to be studied. Ultimately, the decision to proceed with a HSCT remains interdisciplinary while considering the available evidence discussed in this review.

What are the dietary treatment research priorities for inflammatory bowel disease? A short report based on a priority setting partnership with the James Lind Alliance.

BACKGROUND: Treatment of inflammatory bowel disease (IBD) involves a multidisciplinary approach comprising medical management and sometimes surgery. Although diet is central to IBD management, the optimal diet for patients with IBD is uncertain. A UK collaborative partnership within the James Lind Alliance was set up between patients, clinicians and other stakeholders to develop research priorities in IBD. The aim of this short report is to provide a comprehensive summary of the research priority findings relating to diet in the treatment of IBD. METHODS: The James Lind Alliance Priority Setting Partnership process was used to develop research priorities in IBD. In brief, patients, clinicians and other stakeholders were invited to provide up to five treatment uncertainties in IBD. These uncertainties were collated, revised and ranked, leading to a final top 10 research questions in IBD. RESULTS: A total of 1671 uncertainties from 531 participants were collected and refined to exclude duplicates leaving 1253 uncertainties. Of these, 348 were categorised as diet-related and grouped according to topic. There were 206 uncertainties related to how diet can be used to treat IBD or alleviate symptoms. Seventy-two percent of diet-related questions came from patients. One broadly diet-related and two diet-specific treatment uncertainties were included in the top 10 research priorities for IBD. CONCLUSIONS: Dietary treatment options in the management of IBD are important research priorities. Almost three-quarters of diet related questions came from patients, who were particularly interested in how diet can impact disease activity and symptom control.

GPR101 Mutations are not a Frequent Cause of Congenital Isolated Growth Hormone Deficiency.

Patients with Xq26.3 microduplication present with X-linked acrogigantism (X-LAG) syndrome, an early-childhood form of gigantism due to marked growth hormone (GH) hypersecretion from mixed GH-PRL adenomas and hyperplasia. The microduplication includes GPR101, which is upregulated in patients' tumor tissue. The GPR101 gene codes for an orphan G protein coupled receptor that is normally highly expressed in the hypothalamus. Our aim was to determine whether GPR101 loss of function mutations or deletions could be involved in patients with congenital isolated GH deficiency (GHD). Taking advantage of the cohort of patients from the GENHYPOPIT network, we studied 41 patients with unexplained isolated GHD. All patients had Sanger sequencing of the GPR101 gene and array comparative genome hybridization (aCGH) to look for deletions. Functional studies (cell culture with GH secretion measurements, cAMP response) were performed. One novel GPR101 variant, c.589 G>T (p.V197L), was seen in the heterozygous state in a patient with isolated GHD. In silico analysis suggested that this variant could be deleterious. Functional studies did not show any significant difference in comparison with wild type for GH secretion and cAMP response. No truncating, frameshift, or small insertion-deletion (indel) GPR101 mutations were seen in the 41 patients. No deletion or other copy number variation at chromosome Xq26.3 was found on aCGH. We found a novel GPR101 variant of unknown significance, in a patient with isolated GH deficiency. Our study did not identify GPR101 abnormalities as a frequent cause of GH deficiency.

[A Familial Non Medullary Thyroid Carcinoma (FNMTC) : a clinical and genetic update]. / Cancer thyroïdien familial non médullaire: actualités cliniques et génétiques.

The syndrome of Familial Non Medullary Thyroid Carcinoma (FNMTC) includes two or more patients with an isolated non-medullary thyroid cancer (papillary, follicular, anaplastic) within the same family. To diagnose FNMTC, the clinician must exclude a syndromic presentation such as the syndromes of Cowden, Gardner or Werner, and the Carney Complex. Up to now, a hundred families with FNMTC have been genetically studied, including forms with (Ch19p13.2) or without oxyphilia (Ch2q21), in association with a multinodular goiter (Ch14q32), or with a renal cancer (Ch1q21). Several candidate genes of susceptibility have been proposed: SRGAP1, NKX2-1, FOXE1 and HABP2. So far, it is considered that familial cases represent less than 5 % of thyroid cancers. Although rare, these cases represent a unique opportunity to improve our understanding of thyroid cancer. The identification of candidate genes will enrich our knowledge of thyroid cancer pathophysiology. Based on the literature and our experience of the follow-up of eight families with FNMTC, we discuss epidemiological, clinical, pathological and genetic aspects of FNMTC with a view to improve the diagnosis and treatment of this disease.

Le syndrome de «Familial Non Medullary Thyroid Carcinoma¼ (FNMTC) suppose l'existence, au sein d'une même famille, de deux ou plusieurs patients avec un cancer thyroïdien non médullaire isolé (papillaire, folliculaire, anaplasique). Le diagnostic de FNMTC est retenu après exclusion d'une présentation syndromique comme celle liée aux syndromes de Cowden, Gardner, ou Werner et au Complexe de Carney. Une centaine de familles de FNMTC ont été bien caractérisées sur le plan génétique, incluant des formes papillaires avec (Ch19p13.2) ou sans oxyphilie (Ch2q21, 6q22), en association avec un goitre multinodulaire (14q32), ou avec un cancer rénal (Ch1q21). Plusieurs gènes de susceptibilité ont été proposés : SRGAP1, NKX2-1, FOXE1, et HABP2. On estime que les cas familiaux représentent moins de 5 % des cancers thyroïdiens. Bien que minoritaires, ils représentent une occasion exceptionnelle d'approfondir notre compréhension de la tumorigenèse du cancer thyroïdien et d'identifier des gènes candidats pouvant participer à leur physiopathologie. A partir d'une revue de la littérature et de notre expérience sur le suivi de huit familles avec FNMTC, nous discutons des aspects épidémiologiques, cliniques, pathologiques et génétiques permettant d'aboutir à un meilleur diagnostic et à une prise en charge de ce syndrome oncologique.

Post operative complications in a dedicated elective orthopaedic hospital: transfers requiring specialist critical care support.

We aim to report our experience with out of hospital transfers for postoperative complications in a stand-alone elective orthopaedic hospital. We aim to describe the cohort of patients transferred, the rate of transfer and assess the risk factors for transfer. Patients were identified who were transferred out of the hospital to another acute hospital for management of non-routine medical problems. Patient data was collected relating to age, BMI, ASA, type of surgery, nature of the complication, timing and the outcome of transfer. In 2012, 2,853 inpatient surgical procedures were carried out, 51 patients (1.8%) developed a postoperative complication that required out of hospital transfer. Mean age of patients transferred was 67 (12-86) years, mean age of the overall case mix 58 years (0-96) (p = 0.01). 37.7% of the overall case mix of surgeries was made up of primary hip and knee arthroplasty procedures, these patients made up 63.7% of patients transferred out (p = 0.001). Mean BMI recorded was 31.7 (22-48) compared to the mean BMI of the total arthroplasty case mix of 28.8 (20-44) (p = 0.02). 59% of all patients at our institution were ASA category II or III. 76% of patients transferred were ASA category II or III (p = 0.005). We can conclude that patients requiring transfer are typically older. Arthroplasty patients are more likely to require transfer than patients undergoing other orthopaedic procedures. Among the arthroplasty cohort transferred patients will typically have a higher BMI than average. Patients with ASA category II or III make up nearly three quarters of those patients transferred. The mean age of patients transferred is typically older by 9 years.

Older recipient age is paradoxically associated with a lower incidence of chronic GVHD in thymoglobulin recipients: a retrospective study exploring risk factors for GVHD in allogeneic transplantation with thymoglobulin GVHD prophylaxis.

Thymoglobulin (TG) given with conditioning for allogeneic haematopoietic SCT (alloHSCT) is effective in reducing the risk of acute and chronic GVHD (cGVHD). Whether conventional risk factors for GVHD apply to TG-conditioned alloHSCT is unknown. We retrospectively studied 356 adults from three centres who received TG 4.5 mg/kg prior to alloHSCT for haematologic malignancy. Donors were unrelated in 64%. At 3 years, OS was 61% (95% confidence interval (CI) 55-67%), cumulative incidence of relapse was 28% (95% CI 23-33%) and non-relapse mortality was 19% (14-24%). The cumulative incidences of grade 2-4, and grade 3-4 acute GVHD were 23% (95% CI 19-28%) and 10% (95% CI 6-13%), respectively. The cumulative incidence of cGVHD requiring systemic immunosuppression (cGVHD-IS) at 3 years was 32% (95% CI 27-37%). On multivariate analysis, counterintuitively, recipient age over 40 was associated with a significantly decreased risk of cGVHD-IS (P=0.001). We report for the first time a paradoxical association of older age with reduced cGVHD in TG recipients, and conclude that traditional risk factors for GVHD may behave differently in the context of pre-transplant TG.

[Old phenotype and new genotypes. Pituitary adenomas]. / VIEUX PHÉNOTYPE ET NOUVEAUX GÉNOTYPES. Actualités dans le domaine des adénomes hypophysaires.

Gigantism and acromegaly, usually caused by a pituitary adenoma linked inappropriate secretion of growth hormone (GH), are generally considered as very rare diseases, even if, according to some authors, their cumulative prevalence is about 1/5000. Starting from the historical case of a giant from Liège we shall describe the different types of GH pituitary adenomas and their pathophysiology. We shall particularly discuss rare forms of inherited GH secreting pituitary adenomas like the FIPA (familial inherited isolated pituitary adenomas) and the X-LAG (X linked acrogigantism), both described for the first time in Liège, in 2000 and 2014, respectively.

Carriage of the PNPLA3 rs738409 C >G polymorphism confers an increased risk of non-alcoholic fatty liver disease associated hepatocellular carcinoma.

BACKGROUND & AIMS: Subtle inter-patient genetic variation and environmental factors combine to determine disease progression in non-alcoholic fatty liver disease (NAFLD). Carriage of the PNPLA3 rs738409 c.444C >G minor allele (encoding the I148M variant) has been robustly associated with advanced NAFLD. Although most hepatocellular carcinoma (HCC) is related to chronic viral hepatitis or alcoholic liver disease, the incidence of NAFLD-related HCC is increasing. We examined whether rs738409 C >G was associated with HCC-risk in patients with NAFLD. METHODS: PNPLA3 rs738409 genotype was determined by allelic discrimination in 100 European Caucasians with NAFLD-related HCC and 275 controls with histologically characterised NAFLD. RESULTS: Genotype frequencies were significantly different between NAFLD-HCC cases (CC=28, CG=43, GG=29) and NAFLD-controls (CC=125, CG=117, GG=33) (p=0.0001). In multivariate analysis adjusted for age, gender, diabetes, BMI, and presence of cirrhosis, carriage of each copy of the rs738409 minor (G) allele conferred an additive risk for HCC (adjusted OR 2.26 [95% CI 1.23-4.14], p=0.0082), with GG homozygotes exhibiting a 5-fold [1.47-17.29], p=0.01 increased risk over CC. When compared to the UK general population (1958 British Birth Cohort, n=1476), the risk-effect was more pronounced (GC vs. CC: unadjusted OR 2.52 [1.55-4.10], p=0.0002; GG vs. CC: OR 12.19 [6.89-21.58], p<0.0001). CONCLUSIONS: Carriage of the PNPLA3 rs738409 C >G polymorphism is not only associated with greater risk of progressive steatohepatitis and fibrosis but also of HCC. If validated, these findings suggest that PNPLA3 genotyping has the potential to contribute to multi-factorial patient-risk stratification, identifying those to whom HCC surveillance may be targeted.

Effectiveness of 'in-cast' pneumatic intermittent pedal compression for the pre-operative management of closed ankle fractures: a clinical audit.

BACKGROUND: Timing of surgery for ankle fractures is largely dependent on the condition of the surrounding soft-tissues. This study aimed to determine the clinical effectiveness of a pre-operative in-cast artero-venous (AV) impulse device in the management of closed ankle fractures requiring surgery. METHODS: A consecutive series of 64 closed ankle fractures were managed using the AV impulse system prior to surgery. Patients were compared to 73 consecutive closed ankle fractures managed surgically in the same unit immediately prior to the implementation of the AV impulse device study. Outcomes measured were time to surgery, length of hospital stay and surgical site infections. RESULTS: Median length of time to surgery, hospital stay duration and surgical site infections were all significantly reduced in the study group as compared to the control group. CONCLUSIONS: In-cast intermittent AV compression foot pumps in the pre-operative management of closed ankle fractures were associated with earlier surgery, earlier discharge and reduced complications.

Is there a need to teach pharmacogenetics?

Pharmacogenetics/pharmacogenomics has been subject to considerable development during the past 10 years and seems likely to advance even more rapidly in the next decade. Several surveys suggest that initial training for health-care professionals-particularly physicians and pharmacists-frequently includes education in this area, but equipping these professions more generally to deal with ongoing development of the field and to make best use of new knowledge remains an important challenge.

Dietary practices in pyridoxine non-responsive homocystinuria: a European survey.

BACKGROUND: Within Europe, the management of pyridoxine (B6) non-responsive homocystinuria (HCU) may vary but there is limited knowledge about treatment practice. AIM: A comparison of dietetic management practices of patients with B6 non-responsive HCU in European centres. METHODS: A cross-sectional audit by questionnaire was completed by 29 inherited metabolic disorder (IMD) centres: (14 UK, 5 Germany, 3 Netherlands, 2 Switzerland, 2 Portugal, 1 France, 1 Norway, 1 Belgium). RESULTS: 181 patients (73% >16 years of age) with HCU were identified. The majority (66%; n=119) were on dietary treatment (1-10 years, 90%; 11-16 years, 82%; and >16 years, 58%) with or without betaine and 34% (n=62) were on betaine alone. The median natural protein intake (g/day) on diet only was, by age: 1-10 years, 12 g; 11-16 years, 11 g; and >16 years, 45 g. With diet and betaine, median natural protein intake (g/day) by age was: 1-10 years, 13 g; 11-16 years, 20 g; and >16 years, 38 g. Fifty-two percent (n=15) of centres allocated natural protein by calculating methionine rather than a protein exchange system. A methionine-free l-amino acid supplement was prescribed for 86% of diet treated patients. Fifty-two percent of centres recommended cystine supplements for low plasma concentrations. Target treatment concentrations for homocystine/homocysteine (free/total) and frequency of biochemical monitoring varied. CONCLUSION: In B6 non-responsive HCU the prescription of dietary restriction by IMD centres declined with age, potentially associated with poor adherence in older patients. Inconsistencies in biochemical monitoring and treatment indicate the need for international consensus guidelines.
