    The aim of this prospective clinical study was to test auditory function in patients with Laron syndrome, either untreated or treated with insulin-like growth factor I (IGF-I). The study group consisted of 11 patients with Laron syndrome: 5 untreated adults, 5 children and young adults treated with replacement IGF-I starting at bone age Laron syndrome and may be prevented by starting treatment with IGF-I at an early developmental age.

    Growth curves for children with Laron syndrome were constructed on the basis of repeated measurements made throughout infancy, childhood, and puberty in 24 (10 boys, 14 girls) of the 41 patients with this syndrome investigated in our clinic. Growth retardation was already noted at birth, the birth length ranging from 42 to 46 cm in the 12/20 available measurements. The postnatal growth curves deviated sharply from the normal from infancy on. Both sexes showed no clear pubertal spurt. Girls completed their growth between the age of 16-19 years to a final mean (SD) height of 119 (8.5) cm whereas the boys continued growing beyond the age of 20 years, achieving a final height of 124 (8.5) cm. At all ages the upper to lower body segment ratio was more than 2 SD above the normal mean. These growth curves constitute a model not only for primary, hereditary insulin-like growth factor-I (IGF-I) deficiency (Laron syndrome) but also for untreated secondary IGF-I deficiencies such as growth hormone gene deletion and idiopathic congenital isolated growth hormone deficiency. They should also be useful in the follow up of children with Laron syndrome treated with biosynthetic recombinant IGF-I. PMID:8333769

    patients with Laron syndrome, measured by pilocarpine iontophoresis. The patients had significantly lower SSRs than healthy children matched for sex and pubertal stage (P ...). These observations further supported the hypothesis that sweat gland function in humans is under the influence of the GH-insulin-like growth factor-I axis. It remains to be seen whether the decrease in SSR also leads to altered thermoregulation in patients with Laron syndrome....

    We report a case of a parturient with Laron syndrome, a rare form of dwarfism which results from an inability to generate insulin-like growth factor 1. In addition to dwarfism these patients may have craniofacial abnormalities, atlantoaxial instability, spinal stenosis and metabolic, musculoskeletal and genitourinary abnormalities. The patient underwent an urgent caesarean section using combined spinal-epidural anaesthesia. Laron syndrome is reviewed and its anaesthetic implications discussed. Copyright © 2011 Elsevier Ltd.

    Laron-type dwarfism is an autosomal recessive disorder caused by deletions or mutations of the growth hormone receptor gene. It is characterized by high circulating levels of growth hormone (GH) and low levels of insulin-like growth factor I (IGF-I). Patients are refractory to both endogenous and exogenous GH, and present severe growth retardation and obesity. Therapy with recombinant human insulin-like growth factor-I (rhIGF-I) accelerates linear growth. We describe a 2-year old girl with Laron syndrome, who presented with postnatal growth failure and hypoglycaemic seizures. Her evaluation disclosed high GH values during a glucagon test (peak GH value 170 ng/ml) and very low IGF I value (0.1 ng/ml) with no rise following GH administration. The growth velocity improved considerably with the administration of IGF I. Molecular analysis showed a heterozygous mutation on exon 4 of the GH receptor gene, inherited from the mother, a rather puzzling finding considering the clinical findings in mother and infant. This case constitutes the first report of Laron syndrome from Greece.

    Patients with growth hormone (GH) insensitivity (also known as Laron syndome) have been reported from the Mediterranean region and Southern Eucador, with few case reports from India. We present here the clinical and endocrine profile of 9 children with Laron syndrome from India. Nine children diagnosed with Laron syndrome based on clinical features of GH deficiency and biochemical profile suggestive of GH resistance were studied over a period of 5 years from January 2008 to January 2013. Age of presentation was between 2.5-11.5 years. All children were considerably short on contemporary Indian charts with mean (SD) height Z score -5.2 (1.6). However, they were within ± 2 SD on Laron charts. No child was overweight [mean (SD) BMI Z score 0.92 (1.1)]. All children had characteristic facies of GH deficiency with an added feature of prominent eyes. Three boys had micropenis and 1 had unilateral undescended testis. All children had low IGF-1 (Laron syndrome should be suspected in children with clinical features of GH deficiency, high GH levels and low IGF-1/IGFBP-3. These children are in a state of GH resistance and need IGF-1 therapy.

    Recombinant human IGF-1 currently represents the only available treatment option for the Laron Syndrome, a rare human disorder caused by defects in the gene encoding growth hormone receptor, resulting in irreversibly retarded growth. Unfortunately, this treatment therapy, poorly impacts longitudinal growth (13% in females and 19% in males), while burdening the patients with severe side effects, including hypoglycemia, in association with the unfair chore of taking multiple daily injections that cause local intense pain. In this study, we have demonstrated that a single intraperitoneal graft of microencapsulated pig Sertoli cells, producing pig insulin-like growth factor-1, successfully promoted significant proportional growth in the Laron mouse, a unique animal model of the human Laron Syndrome. These findings indicate a novel, simply, safe and successful method for the cell therapy-based cure of the Laron Syndrome, potentially applicable to humans. Copyright © 2012 Elsevier B.V.

    There are different opinions concerning changes in glucose metabolism in patients with Laron syndrome. In this paper we discuss the treatment results of our patient with Laron syndrome who developed diabetes during late adolescence. A 19-year-old boy with Laron syndrome was referred to our clinic for follow-up. He had been diagnosed with Laron syndrome (LS) at 4 years old and rIGF-1 therapy was initiated. After 4 months the treatment was discontinued. At the age of 17, rIGF-1 therapy was restarted. A height gain of 8.8 cm. was observed during the 2-year treatment period. He was admitted to our hospital at the age of 19 years following discontinuation of the therapy. At that time, his height was 142 cm, and weight for height was 136%. His blood glucose was 85 mg/dL (4.72 mmol/L), insulin was 26.39 pmol/L, and HbA1c was 5.4%. At the age of 20, when he has not been receiving IGF-1 therapy for 1 year, his weight for height was 143 cm. Laboratory evaluation revealed that fasting blood glucose was 176 mg/dL (9.77 mmol/L), fasting insulin was 29.86 pmol/L, and HbA1c was 7.5%. Primary insulin therapy was then initiated. His parents both had a diagnosis of type 2 diabetes. Insulin therapy was switched to oral antidiabetic (OAD) therapy at the end of the second year because of a normal C-peptide level of 0.8 nmol/L under insulin therapy. After 6 months of OAD, HbA1c was 5.7%. The treatment was then switched to IGF-1 therapy, but his blood glucose profile was impaired and OAD therapy was restarted. In conclusion, we observed that genetic susceptibility and abdominal obesity caused type 2 diabetes in this patient. We believe that oral antidiabetic agents and life-style changes may be the appropriate approach when diabetes is developed in LS patients.

    Laron syndrome [growth hormone (GH) insensitivity syndrome] is a hereditary dwarfism resulting from defects in the GH receptor (GHR) gene. GHR deficiency has not been reported in mammals other than humans. Many aspects of GHR dysfunction remain unknown because of ethical and practical limitations in studying humans. To create a mammalian model for this disease, we generated mice bearing a disrupted GHR/binding protein (GHR/BP) gene through a homologous gene targeting approach. Homozygous GHR/BP knockout mice showed severe postnatal growth retardation, proportionate dwarfism, absence of the GHR and GH binding protein, greatly decreased serum insulin-like growth factor I and elevated serum GH concentrations. These characteristics represent the phenotype typical of individuals with Laron syndrome. Animals heterozygous for the GHR/BP defect show only minimal growth impairment but have an intermediate biochemical phenotype, with decreased GHR and GH binding protein expression and slightly diminished insulin-like growth factor I levels. These findings indicate that the GHR/BP-deficient mouse (Laron mouse) is a suitable model for human Laron syndrome that will prove useful for the elucidation of many aspects of GHR/BP function that cannot be obtained in humans.

    Laron syndrome is a rare disease caused by mutations of the growth hormone receptor (GHR), inheriting in an autosomal manner. To better understand the pathogenesis and to develop therapeutics, we generated a miniature pig model for this disease by employing ZFNs to knock out GHR gene. Three types of F0 heterozygous pigs (GHR(+/4bp), GHR(+/2bp), GHR(+/3bp)) were obtained and in which no significant phenotypes of Laron syndrome were observed. Prior to breed heterozygous pigs to homozygosity (GHR(4bp/4bp)), pig GHR transcript with the 4 bp insert was evaluated in vitro and was found to localize to the cytoplasm rather than the membrane. Moreover, this mutated transcript lost most of its signal transduction capability, although it could bind bGH. GHR(4bp/4bp) pigs showed a small body size and reduced body weight. Biochemically, these pigs exhibited significantly elevated levels of GH and decreased levels of IGF-I. These results resemble the phenotype observed in Laron patients, suggesting that these pigs could serve as an ideal model for Laron syndrome to bridge the gaps between mouse model and human.

    Laron syndrome, growth hormone (GH) insensitivity syndrome, caused by a mutation of the GH receptor (GHR) gene, is extremely rare in the Chinese population. We report a Chinese girl diagnosed with Laron syndrome at age 1.9 years with height -4.9 SDS, basal GH 344 mIU/ml, IGF-I <12 ng/ml, IGFBP-3 <0.2 mg/ml, and undetectable GHBP. A novel mutation of the GHR, not previously described, was identified at the donor splice site of intron 6.

    To study the metabolic parameters which may affect the excessive weight of treated and untreated patients with Laron Syndrome. Body composition, daily caloric intake and resting energy expenditure (REE), when possible, were measured for each patient. Caloric intake was calculated based on 7-day food records, REE was measured by indirect calorimetry and body composition was determined by dual energy X-ray absorptiometry (DEXA). Nine untreated adult subjects with Laron Syndrome (6 female subjects, 3 male subjects) aged 28-53 years and 4 girls with Laron Syndrome treated by insulin-like growth factor-I (IGF-I) 120-150 μg/kg/d were included in the study. Patients with Laron Syndrome have an abnormally high body fat (BF) mass (54 ± 10% of body weight) and a relatively low lean body mass (LBM) compared to a healthy normal population. Energy intake varied but in most of the patients was not significantly higher than the measured REE. The REE corrected for LBM was higher than expected, based on our norms for healthy adults. The mean distribution of energy sources in the food was 47% carbohydrates, 17% protein and 36% fat. The severe obesity of patients with Laron Syndrome is not due to hyperphagia or hypometabolism. © 2009 Asian Oceanian Association for the Study of Obesity . Published by Elsevier Ltd.

Material and Methods: Nine children diagnosed with Laron syndrome based on clinical features of GH deficiency and biochemical profile suggestive of GH resistance were studied over a period of 5 years from January 2008 to January 2013. Results and Discussion: Age of presentation was between 2.5-11.5 years. All children were considerably short on contemporary Indian charts with mean (SD height Z score -5.2 (1.6. However, they were within ± 2 SD on Laron charts. No child was overweight [mean (SD BMI Z score 0.92 (1.1]. All children had characteristic facies of GH deficiency with an added feature of prominent eyes. Three boys had micropenis and 1 had unilateral undescended testis. All children had low IGF-1 (<5 percentile and IGFP-3 (<0.1 percentile with high basal and stimulated GH [Basal GH mean (SD = 13.78 (12.75 ng/ml, 1-h stimulated GH mean (SD = 46.29 (25.68 ng/ml]. All children showed poor response to IGF generation test. Conclusion: Laron syndrome should be suspected in children with clinical features of GH deficiency, high GH levels and low IGF-1/IGFBP-3. These children are in a state of GH resistance and need IGF-1 therapy.

    The purpose of the present study was to investigate whether lifelong secretion of high levels of GH, characteristic of Laron syndrome, leads to an increase in the size of the pituitary gland. Eleven patients (six females, five males) with Laron syndrome underwent magnetic resonance imaging of the pituitary region with a system operating at 0.5 T. There were nine adults aged 36-68 Years and two children, a 4-Year-old boy and a 9-Year-old girl. The latter patient had been treated with IGF-I (150-180 mg/kg per day) since the age of 3 Years; all the other patients were untreated. The height of the adenohypophysis was measured on the sagittal images and compared with reference values for age and sex. The height of the adenohypophysis was within the normal range for age and gender in all patients, except for one male, who had a small gland. No congenital anomalies of the pituitary-hypothalamic region were detected. Despite the lifelong high levels of GH, no pituitary hypertrophy was detected. The anatomy of the pituitary-hypothalamic region in Laron syndrome is normal.

    To better understand the molecular genetic basis and genetic epidemiology of Laron syndrome (growth-hormone insensitivity syndrome), we analyzed the growth-hormone receptor (GHR) genes of seven unrelated affected individuals from the United States, South America, Europe, and Africa. We amplified all nine GHR gene exons and splice junctions from these individuals by PCR and screened the products for mutations by using denaturing gradient gel electrophoresis (DGGE). We identified a single GHR gene fragment with abnormal DGGE results for each affected individual, sequenced this fragment, and, in each case, identified a mutation likely to cause Laron syndrome, including two nonsense mutations (R43X and R217X), two splice-junction mutations, (189-1 G to T and 71 + 1 G to A), and two frameshift mutations (46 del TT and 230 del TA or AT). Only one of these mutations, R43X, has been previously reported. Using haplotype analysis, we determined that this mutation, which involves a CpG dinucleotide hot spot, likely arose as a separate event in this case, relative to the two prior reports of R43X. Aside from R43X, the mutations we identified are unique to patients from particular geographic regions. Ten GHR gene mutations have now been described in this disorder. We conclude that Laron syndrome is caused by diverse GHR gene mutations, including deletions, RNA processing defects, translational stop codons, and missense codons. All the identified mutations involve the extracellular domain of the receptor, and most are unique to particular families or geographic areas. Images Figure 1 Figure 2 PMID:8488849

    Laron syndrome (LS) is a rare, genetic disorder inherited in an autosomal recessive manner. The disease is caused by mutations of the growth hormone (GH) gene, leading to GH/insulin-like growth factor type 1 (IGF1) signalling pathway defect. Patients with LS have characteristic biochemical features, such as a high serum level of GH and low IGF1 concentration. Laron syndrome was first described by the Israeli physician Zvi Laron in 1966. Globally, around 350 people are affected by this syndrome and there are two large groups living in separate geographic regions: Israel (69 individuals) and Ecuador (90 individuals). They are all characterized by typical appearance such as dwarfism, facial phenotype, obesity and hypogenitalism. Additionally, they suffer from hypoglycemia, hypercholesterolemia and sleep disorders, but surprisingly have a very low cancer risk. Therefore, studies on LS offer a unique opportunity to better understand carcinogenesis and develop new strategies of cancer treatment.

    Three children of two Taiwanese families were diagnosed with Laron syndrome, two sisters and one boy. Both sets of parents were consanguineous. Clinically, all three presented with the typical craniofacies of Laron syndrome, consisting of prominent forehead and hypoplastic nasal bridge, high-pitched voice, short stature, and central obesity. Biochemically, their levels of serum IGF-I were less than 5 microg/ml before and after an IGF-I generation test, and levels of IGFBP-3 were reduced in all three patients. Sequence analysis of the growth hormone receptor gene revealed that all three carried a homozygous missense D152G mutation in exon 6.

    Patients with Laron syndrome have an inborn growth hormone resistance. We investigated abnormalities in the upper airways and cervical spine in patients with Laron syndrome. We prospectively examined 11 patients (one child aged 9 years and 10 adults aged 36-68 years), 10 of whom underwent MR imaging of the spine or head; nine, radiography of the cervical spine; and four, CT of C1-C2. The width of the spinal canal was evaluated visually and quantitatively and compared with reference values. The smallest diameter of the oropharynx and the thickness of the palate were measured and compared with reference values. Nine age-matched female patients referred for MR imaging for unrelated reasons served as control subjects. Cervical spinal stenosis was present in seven of the adult patients, within a confidence interval of 95%. Anomaly of the dens compatible with os odontoideum was present in three patients, causing focal myelomalacia in two. The atlanto-odontoid joint showed osteoarthritic changes in six of the adult patients. The mediolateral diameter of the oropharynx was significantly smaller in the patients with Laron syndrome than in the control subjects (P Laron syndrome develop significant narrowing of the cervical spinal canal and early degenerative changes of the atlanto-odontoid joint. Laron syndrome is associated with os odontoideum causing myelomalacia. The dimensions of the oropharynx are small. Patients may be prone to neurologic morbidity and sleep disturbances. Routine MR imaging of the cervical spine is recommended in these patients.

    Laron syndrome is a rare cause of short stature due to an abnormality of growth hormone receptor (GHR). It is characterized by poor phenotype-genotype correlation and geographic predilection essentially in the Mediterranean rim, the Middle East and Indian subcontinent. This syndrome corresponds to an endogenous and exogenous complete insensitivity of GH and manifests by early hypoglycemia, an extremely severe short stature and dysmorphic features contrasting with high levels of circulating GH. To date, treatment with recombinant IGF1 is the only treatment option that has improved the terrible prognosis in these patients but does not actually realize the conditions for genuine replacement therapy.

    Laron syndrome is an autosomal recessive disorder caused by defects of growth hormone receptor (GHR) gene. It is characterized by severe postnatal growth retardation and characteristic facial features as well as high circulating levels of growth hormone (GH) and low levels of insulin-like growth factor I (IGF-I) and insulin-like growth factor binding protein-3 (IGFBP-3). This report described the clinical features and GHR gene mutations in 2 siblings with Laron syndrome in a Chinese family. Their heights and weights were in the normal range at birth, but the growth was retarded after birth. When they presented to the clinic, the heights of the boy (8 years old) and his sister (11 years old) were 80.0 cm (-8.2 SDS) and 96.6 cm (-6.8 SDS) respectively. They had typical appearance features of Laron syndrome such as short stature and obesity, with protruding forehead, saddle nose, large eyes, sparse and thin silky hair and high-pitched voice. They had higher basal serum GH levels and lower serum levels of IGF-I, IGFBP-3 and growth hormone binding protein (GHBP) than normal controls. The peak serum GH level after colonidine and insulin stimulations in the boy was over 350 ng/mL. After one-year rhGH treatment, the boy's height increased from 80.0 cm to 83.3 cm. The gene mutation analysis revealed that two patients had same homozygous mutation of S65H (TCA -->CCA) in exon 4, which is a novel gene mutation. It was concluded that a definite diagnosis of Laron syndrome can be made based on characteristic appearance features and serum levels of GH, IGF-I, IGFBP-3 and GHBP. The S65H mutation might be the cause of Laron syndrome in the two patients.

    Growth hormone (GH) insensitivity syndrome (Laron syndrome) is known to be caused by genetic disorders of the GH-IGF-1 axis. Although many mutations in the GH receptor have been identified, there have been only a few reports of deletions of the GH receptor gene. A Japanese adult female patient with Laron syndrome was subjected to chromosome analysis with basic G-banding and also with a high accuracy technique. Each exon of the GH receptor gene was amplified by means of PCR. Since this patient was diagnosed with osteoporosis, the effects of alendronate on bone mineral density (BMD) were also examined. The chromosome analysis with the high accuracy technique demonstrated a large deletion of the short arm in one allele of chromosome 5 from p11 to p13.1 [46, XX, del (5) (p11-p13.1)]. PCR amplification of exons of the GH receptor gene showed that only exons 2 and 3 were amplified. Low-dose IGF-1 administration (30microg/kg body weight) failed to increase her BMD, whereas alendronate administration resulted in an increase associated with a decrease in urinary deoxypyridinoline (DPD) and serum osteocalcin concentrations. The GH receptor gene of the patient was shown to lack exons 4-10. To the best of our knowledge, this is the third case report of Laron syndrome with large GH receptor deletion. Alendronate was effective for the enhancement of BMD.

GHR deficiency has not been reported in mammals other than humans. Many aspects of GHR dysfunction remain unknown because of ethical and practical limitations in studying humans. To create a mammalian model for this disease, we generated mice bearing a disrupted GHR/binding protein (GHR/BP) gene through a homologous gene targeting approach. Homozygous GHR/BP knockout mice showed severe postnatal growth retardation, proportionate dwarfism, absence of the GHR and GH binding protein, greatly decreased serum insulin-like growth factor I and elevated serum GH concentrations. These characteristics represent the phenotype typical of individuals with Laron syndrome. Animals heterozygous for the GHR/BP defect show only minimal growth impairment but have an intermediate biochemical phenotype, with decreased GHR and GH binding protein expression and slightly diminished insulin-like growth factor I levels. These findings indicate that the GHR/BP-deficient mouse (Laron mouse) is a suitable model for human Laron syndrome that will prove useful for the elucidation of many aspects of GHR/BP function that cannot be obtained in humans.

    To describe the characteristics of untreated and recombinant insulin-like growth factor 1 (IGF-1)- treated patients with the Laron syndrome (LS) as seen in our clinic over a period of over 50 years. In 1966, we reported a new disease, characterized by dwarfism (-4 to -10 height standard deviation score) typical facial features, small head circumference, obesity, and small genitalia. They resembled congenital growth hormone (GH) deficiency but had high levels of serum human GH and low IGF-1. Since then, our cohort grew to 69 patients, consisting of Jews of oriental origin, Muslins, and Christians originating from the Middle East or Mediterranean area. Many belong to consanguineous families. Molecular genetic investigations revealed that these patients had deletions or mutations in the GH receptor gene, but only individuals homozygous for this defect express the disease, coined "Laron syndrome" (LS; Online Mendelian Inheritance in Man# 262500). During childhood, LS patients grow slowly, have a retarded bone age and sexual development, but reach full sexual development. The treatment of LS is recombinant IGF-1, which stimulates the linear growth but increases the degree of obesity. Adult-age patients with congenital IGF-1 deficiency are protected from cancer but can develop insulin resistance, glucose intolerance, diabetes, and cardiovascular disease. Due to pathologic changes in the brain related to the type of molecular defect in the GH receptor, they vary in their intellectual capacity. A number of LS patients marry, and with help of pregestational genetic diagnosis, have healthy children. LS is a unique disease model presenting a dissociation between GH and IGF-1 activity.

    To investigate abnormalities in the craniofacial structures and in the brain in patients with Laron syndrome. Eleven patients with classical Laron syndrome, nine untreated adults aged 36-68 years and two children aged 4 and 9 years (the latter treated by IGF-I), were studied. Magnetic resonance images of the brain were obtained in all the patients. One patient also underwent computed tomography. The maximal diameter of the maxillary and frontal sinuses was measured and compared with reference values, the size of the sphenoid sinus was evaluated in relation to the sella, and the mastoids were evaluated qualitatively (small or normal). The brain was evaluated for congenital anomalies and parenchymal lesions. In the adult untreated patients, the paranasal sinuses and mastoids were small; in six patients, the bone marrow in the base of the skull was not mature. The diploe of the calvaria was thin. On computed tomography in one adult patient, the sutures were still open. A minimal or mild degree of diffuse brain parenchymal loss was seen in ten patients. One patient demonstrated a lacunar infarct and another periventricular high signals on T2-weighted images. Two patients had cerebellar atrophy. The present study has demonstrated the important role IGF-I plays in the development of the brain and bony structures of the cranium.

    Laron syndrome (LS) is a unique model of congenital IGF-I deficiency. It is characterized by dwarfism and obesity, and is caused by deletion or mutations of the growth hormone receptor (GH-R) gene. It is hypothesized that LS is an old disease originating in Indonesia and that the mutated gene spread to South Asia, the Middle East, the Mediterranean region and South America.

    Laron Syndrome, first described in Israel, is a form of dwarfism similar to isolated growth hormone deficiency caused by molecular defects in the GH receptor gene. To characterize the molecular defects of the GH-R in Laron syndrome patients followed in our clinic. Of the 63 patients in the cohort, we investigated 31 patients and 32 relatives belonging to several ethnic origins. Molecular analysis of the GH-R gene was performed using the single strand conformation polymorphism and DNA sequencing techniques. Eleven molecular defects including a novel mutation were found. Twenty-two patients carried mutations in the extracellular domain, one in the transmembrane domain, and 3 siblings with typical Laron syndrome presented a normal GH-R. Of interest are, on one hand, different mutations within the same ethnic groups: W-15X and 5, 6 exon deletion in Jewish-Iraqis, and E180 splice and 5, 6 exon deletion in Jewish-Moroccans; and on the other hand, identical findings in patients from distinct regions: the 785-1 G to T mutation in an Israeli-Druze and a Peruvian patient. A polymorphism in exon 6, Gly168Gly, was found in 15 probands. One typical Laron patient from Greece was heterozygous for R43X in exon 4 and heterozygous for Gly168Gly. In addition, a novel mutation in exon 5: substitution of T to G replacing tyrosine 86 for aspartic acid (Y86D) is described. This study demonstrates: a) an increased focal incidence of Laron syndrome in different ethnic groups from our area with a high incidence of consanguinity; and b) a relationship between molecular defects of the GH-R, ethnic group and geographic area.

    Facial morphometry using computerised image analysis was performed on patients with growth hormone receptor deficiency (Laron syndrome) from an inbred population of southern Ecuador. Morphometrics were compared for 49 patients, 70 unaffected relatives, and 14 unrelated persons. Patients with growth hormone receptor deficiency showed significant decreases in measures of vertical facial growth as compared to unaffected relatives and unrelated persons with short stature from other causes. This report validates and quantifies the clinical impression of foreshortened facies in growth hormone receptor deficiency. Images PMID:7815422

    A description of the clinical, biochemical and endocrinological features of the classical form of the syndrome of primary growth hormone (GH) resistance (Laron syndrome) is presented including the progressive changes during follow-up from infancy into adulthood. The main diagnostic features are: severe growth retardation, acromicria, small gonads and genitalia, and obesity. Serum GH levels are elevated and insulin-like growth factor-I (IGF-I) values are low and do not rise upon stimulation by exogenous hGH. The pathogenesis of this syndrome is due to various molecular defects from exon deletion to nonsense, frameshift, splice and missense mutations in the GH receptor (GH-R) gene or in its post-receptor pathways.

    We have previously reported on the linear growth, growth of the head circumference and foot length in untreated and IGF-I treated patients with Laron syndrome (LS) (primary GH insensitivity). To assess the size and growth of the hands in patients with LS from early childhood to adult age. Ten IGF-I treated children with LS (4 M, 6 F) and 24 untreated patients (10 M, 14 F) were studied. Measurements of palm length were made on available standardized hand X-rays from infancy to adult age. The measurements were compared to normal references and SD values were calculated for each measurement. The growth of the hand was compared to the concomitant height of the body. Hand SDS in untreated patients with LS decreased with age, from a mean of -2.8 +/- 0.7 (age 1-3 years) to -7.3 +/- 0.8 (age 13-15 years) and to -9.0 +/- 3.9 (age 40-50 years). During 9 years of IGF-I treatment the hand size deficit SDS did not improve in contradistinction to the height SDS which decreased from -6.2 +/- 1.2 to -3.9 +/- 0.5. Congenital IGF-I deficiency, as in Laron syndrome, profoundly affects the size and growth of the hand as part of its growth retardation characteristics, resulting in acromicria.

    Full Text Available Abstract Introduction Primary growth hormone resistance or growth hormone insensitivity syndrome, also known as Laron syndrome, is a hereditary disease caused by deletions or different types of mutations in the growth hormone receptor gene or by post-receptor defects. This disorder is characterized by a clinical appearance of severe growth hormone deficiency with high levels of circulating growth hormone in contrast to low serum insulin-like growth factor 1 values. Case presentation We report the case of a 15-year-old Caucasian girl who was diagnosed with Silver-Russell syndrome at the age of four and a half years. Recombinant growth hormone was administered for 18 months without an appropriate increase in growth velocity. At the age of seven years, her serum growth hormone levels were high, and an insulin-like growth factor 1 generation test did not increase insulin-like growth factor 1 levels (baseline insulin-like growth factor 1 levels, 52 μg/L; reference range, 75 μg/L to 365 μg/L; and peak, 76 μg/L and 50 μg/L after 12 and 84 hours, respectively, from baseline. The genetic analysis showed that the patient was homozygous for the R217X mutation in the growth hormone receptor gene, which is characteristic of Laron syndrome. On the basis of these results, the diagnosis of primary growth hormone insensitivity syndrome was made, and recombinant insulin-like growth factor 1 therapy was initiated. The patient's treatment was well tolerated, but unexplained central hypothyroidism occurred at the age of 12.9 years. At the age of 15 years, when the patient's sexual development was almost completed and her menstrual cycle occurred irregularly, her height was 129.8 cm, which is 4.71 standard deviations below the median for normal girls her age.

    Clinical and laboratory investigations starting in 1958 of a group of dwarfed children resembling isolated GH deficiency but who had very high serum levels of GH led to the description of the syndrome of primary GH resistance or insensitivity (Laron syndrome) and subsequently to the discovery of its molecular defects residing in the GH receptor and leading to an inability of IGF-I generation. With the biosynthesis of IGF-I in 1986, therapeutic trials started. Continuously more and more patients are being diagnosed in many parts of the world with a variety of molecular defects. This syndrome proved to be a unique model that enables the study of the consequences of GH receptor defects, the physiopathology of GH-IGF-I disruption, and comparison of the GH-independent IGF-I effects. This review presents the personal experience gained from the study follow-up and treatment of the 60 patients followed up for many years in the Israeli cohort.

    To investigate abnormalities in the skeleton (with the exclusion of the skull, cervical spine, hands and feet) in patients with Laron syndrome, who have an inborn growth hormone resistance and congenital insulin-like growth factor-1 (IGF-1) deficiency. The study group was composed of 15 untreated patients with Laron syndrome (seven male and eight female) aged 21-68 years. Plain films of the axial and appendicular skeleton were evaluated retrospectively for abnormalities in structure and shape. The cortical width of the long bones was evaluated qualitatively and quantitatively (in the upper humerus and mid-femur), and the cortical index was calculated and compared with published references. Measurements were taken of the mid-anteroposterior and cranio-caudal diameters of the vertebral body and spinous process at L3, the interpedicular distance at L1 and L5, and the sacral slope. Thoracic and lumbar osteophytes were graded on a 5-point scale. Values were compared with a control group of 20 healthy persons matched for age. The skeleton appeared small in all patients. No signs of osteopenia were visible. The cortex of the long bones appeared thick in the upper limbs in 11 patients and in the lower limbs in four. Compared with the reference values, the cortical width was thicker than average in the humerus and thinner in the femur. The vertebral diameters at L3 and the interpedicular distances at L1 and L5 were significantly smaller in the patients than in the control subjects (P < 0.001); however, at L5 the canal was wider, relative to the vertebral body. The study group had a higher rate of anterior osteophytes in the lumbar spine than the controls had, and their osteophytes were also significantly larger. In the six patients for whom radiographs of the upper extremity in its entirety were available on one film, the ulna appeared to be rotated. In one 22-year-old man, multiple epiphyses were still open. Congenital IGF-1 deficiency leads to skeletal abnormalities

    The follow-up of a large cohort of patients with Laron syndrome (LS) from infancy to adult age has enabled us to determine the effects of long-term insulin-like growth factor-I (IGF-I) deficiency on auxological, biochemical, physiological and psychological parameters. We found that early and continuous IGF-I deficiency (the anabolic effector of growth hormone) causes dwarfism, acromicria, organomicria, marked obesity, insulin resistance, retardation of skeletal maturation and osteoporosis, as well as muscular and central nervous tissue underdevelopment, and a series of biochemical changes including hypercholesterolemia. These multiple pathologies impair the quality of life of these patients. It is concluded that patients with LS need IGF-I replacement treatment throughout life.

    Fanconi anemia (FA) is a condition characterized by genetic instability and short stature, which is due to growth hormone (GH) deficiency in most cases. However, no apparent relationships have been identified between FA complementation group genes and GH. In this study, we thereby considered an association between FA and Laron syndrome (LS) (insulin-like growth factor 1 [IGF-1] deficiency). A 21-year-old female Mexican patient with a genetic diagnosis of FA was referred to our research department for an evaluation of her short stature. Upon admission to our facility, her phenotype led to a suspicion of LS; accordingly, serum levels of IGF-1 and IGF binding protein 3 were analyzed and a GH stimulation test was performed. In addition, we used a next-generation sequencing approach for a molecular evaluation of FA disease-causing mutations and genes involved in the GH-IGF signaling pathway. Tests revealed low levels of IGF-1 and IGF binding protein 3 that remained within normal ranges, as well as a lack of response to GH stimulation. Sequencing confirmed a defect in the GH receptor signaling pathway. To the best of our knowledge, this study is the first to suggest an association between FA and LS. We propose that IGF-1 administration might improve some FA complications and functions based upon IGF-1 beneficial actions observed in animal, cell and indirect clinical models: erythropoiesis modulation, immune function improvement and metabolic regulation.

    Laron syndrome is an autosomal disease resulting from mutations in the growth hormone receptor (GHR) gene. The only therapeutic treatment for Laron syndrome is recombinant insulin-like growth factor I (IGF-I), which has been shown to have various side effects. The improved Laron syndrome models are important for better understanding the pathogenesis of the disease and developing corresponding therapeutics. Pigs have become attractive biomedical models for human condition due to similarities in anatomy, physiology, and metabolism relative to humans, which could serve as an appropriate model for Laron syndrome. To further improve the GHR knockout (GHRKO) efficiency and explore the feasibility of precise DNA deletion at targeted sites, the dual-sgRNAs/Cas9 system was designed to target GHR exon 3 in pig fetal fibroblasts (PFFs). The vectors encoding sgRNAs and Cas9 were co-transfected into PFFs by electroporation and GHRKO cell lines were established by single cell cloning culture. Two biallelic knockout cell lines were selected as the donor cell line for somatic cell nuclear transfer for the generation of GHRKO pigs. The genotype of colonies, cloned fetuses and piglets were identified by T7 endonuclease I (T7ENI) assay and sequencing. The GHR expression in the fibroblasts and piglets was analyzed by confocal microscopy, quantitative polymerase chain reaction (q-PCR), western blotting (WB) and immunohistochemical (IHC) staining. The phenotype of GHRKO pigs was recapitulated through level detection of IGF-I and glucose, and measurement of body weight and body size. GHRKO F1 generation were generated by crossing with wild-type pigs, and their genotype was detected by T7ENI assay and sequencing. GHRKO F2 generation was obtained via self-cross of GHRKO F1 pigs. Their genotypes of GHRKO F2 generation was also detected by Sanger sequencing. In total, 19 of 20 single-cell colonies exhibited biallelic modified GHR (95%), and the efficiency of DNA deletion mediated by dual

    Fifty patients with primary GH resistance (Laron syndrome) due to molecular defects of the GH receptor or post-receptor pathways were followed from infancy through adulthood. This condition leading to long-term insulin-like growth factor-I (IGF-I) deprivation caused marked growth retardation (-4 to 8 height SD), acromicia, organomicria, retarded development of the skeletal and muscular systems, a small cranium, slow motor development, and impairment of intellectual development in some of the patients. In addition, there was progressive obesity, insulin resistance, a tendency for hypoglycemia, followed later in life by hypercholesterolemia and by glucose intolerance and even diabetes. IGF-I treatment of children with Laron syndrome, by our and other groups (150-240 microg/day sc), stimulated growth (8 cm in the first year and 4-5 cm in the following years) and normalized the biochemical abnormalities. Overdosage led to adverse effects such as hypoglycemia, edema, swelling of soft tissues, and hyperandrogenism. It is concluded that primary IGF-I deprivation induces severe auxological, biochemical, and hormonal changes, the only treatment being biosynthetic IGF-I administration.

    Classical Laron syndrome is a recessive disease of primary insulin-like growth factor 1 (IGF-1) deficiency and primary growth hormone insensitivity. Affected children have, among other defects, sparse hair growth and frontal recessions. The hair is thin and easy to pluck. Young adults have various degrees of alopecia, more pronounced in males. The aim of the present study was to investigate the effect of primary IGF-1 deficiency on hair structure. The study sample included 11 patients with Laron syndrome--5 children (2 untreated) and 6 adults (5 untreated). Hairs were examined by light and electron microscopy. The most significant structured defect, pili torti et canaliculi, was found in 2 young, untreated patients. Grooving, tapered hair and trichorrhexis nodosa were found in the remainder. IGF-1-treated patients had either none or significantly fewer pathological changes compared to the untreated patients. This is the first documentation of the role of primary IGF-1 deficiency on hair structure in human beings. Copyright 2004 S. Karger AG, Basel

    Mutations localized in the Growth Hormone Receptor (GHR) gene are often associated with the pathogenesis of Laron Syndrome, an autosomal recessive hereditary disorder characterized by severe growth retardation. Biochemically, patients present normal to high circulating GH levels, in presence of very low or undetectable IGF-I levels, which do not rise after rhGH treatment. We describe the case of a 3.8 years old girl with symmetrical short stature (-3.76 SDS), low IGF-1 and IGFBP-3, in presence of normal GH levels. Parents were not relatives and there was no family history of short stature. During the second day of birth, she developed severe hypoglycaemia that required glucose infusion. She presented frontal bossing and depressed nasal bridge. IGF-1 generation test showed no response, suggesting a GH resistance evidence. In the hypothesis of Laron Syndrome, we decided to perform a molecular analysis of Growth Hormone Receptor (GHR) gene. This analysis demonstrated that the patient was compound heterozygote for two missense mutations. GHR gene mutations are a well demonstrated cause of GH insensitivity. In heterozygous patients, probably the normal stature may be achieved by a compensatory mechanism of GH secretion or signalling. On the contrary, in homozygous or compound heterozygous patients these compensatory mechanisms are inadequate, and short stature may be the consequence.

    Laron syndrome (LS) is an autosomal recessive disease caused by deletions or mutations in the GH receptor gene leading to an inability of insulin-like growth factor I (IGF-I) generation. Among the major resulting body changes are dwarfism and obesity. The only effective treatment is daily administration of biosynthetic IGF-I. Body composition determination by DEXA (dual energy X-ray absorptiometry) of three girls with LS treated by IGF-I for 1, 3 and 11 1/2 years, respectively, revealed that concomitantly with the increase in growth there was a significant increase in body adipose tissue to double or triple the normal values. Due to the underdevelopment of the muscular and skeletal systems body mass index (BMI) did not accurately reflect the degree of obesity. In conclusion, IGF-I similar to insulin, exerts an adipogenic effect.

    Untreated patients with congenital growth hormone deficiency (GHD) and IGF-I deficiency are characterized not only by dwarfism but also by acromicria and organomicria, such as the heart. We assessed cardiac dimensions and function in very young patients with Laron syndrome (LS) undergoing IGF-I replacement therapy. Two to seven echocardiographic measurements were performed during IGF-I replacement therapy on male (n=4) and female (n=4) LS -patients, mean+/-SD age of 7.1+/-3.6 years (range 1.6-11.6 years), weight 16.1+/-9.7 kg, and height 89.9+/-18.5 cm. As aged- and gender-matched controls served 44 healthy children, age: 8.7+/-5.5 years, weight: 36.1+/-22.4 kg, and height: 129.7+/-33.1cm. Data of LS patients were normalized to body surface area and compared to the control group as well as nomograms of normal echocardiographic parameters for this age group. Left ventricular diastolic and systolic dimensions (LVDD/ LVSD, mm) and LV mass (gr) were significantly smaller in boys and girls with IGF-I treated LS compared with controls while the shortening fraction (%) and intraventricular septum thickness (mm) were similar. When compared with standard values for this age group, all treated LS patients were within 1 standard deviation of the mean. IGF-I therapy of young patients with Laron syndrome maintain LV dimensions and function within the normal range of aged-matched controls.

    Deletions and mutations in the growth hormone receptor (GHR) gene are the underlying etiology of Laron syndrome (LS) or growth hormone (GH) insensitivity syndrome (GHIS), an autosomal recessive disease. Most patients are distributed in or originate from Mediterranean and Middle-Eastern countries. Sixty mutations have been described so far. We report a novel mutation in the GHR gene in a patient with LS. Genomic DNA sequencing of exon 5 revealed a TT insertion at nucleotide 422 after codon 122. The insertion resulted in a frameshift introducing a premature termination codon that led to a truncated receptor. We present clinical, biochemical and molecular evidence of LS as the result of this homozygous insertion.

    Approximately 60 cases of GHRD (Laron syndrome) were reported before 1990 and half of these were from Israel. We have described 47 additional patients from an inbred population of South Ecuador and have emphasized certain clinical features including: markedly advanced osseous maturation for height age; normal body proportions in childhood but child-like proportions in adults; much greater deviation of stature than head size, giving an appearance of large cranium and small facies; underweight in childhood despite the appearance of obesity and true obesity in adulthood; blue scleras; and limited elbow extension. The Ecuadorean patients differed markedly and most importantly from the other large concentration, in Israel, by being of normal or superior intelligence, suggesting a unique linkage in the Ecuadorean population. The Ecuadorean population also differed in that those patients coming from Loja province had a markedly skewed sex ratio (19 females: 2 males), while those from El Oro province had a normal sex distribution (14 females: 12 males). The phenotypic similarity between the El Oro and Loja patients indicates that this abnormal sex distribution is not a direct result of the GHRD.

    Growth Hormone (GH) is a 22 kDa protein that has effects on growth and glucose and fat metabolisms. These effects are initiated by binding of growth hormone (GH) to growth hormone receptors (GHR) expressed in target cells. Mutations or deletions in the growth hormone receptor cause an autosomal disorder called Laron-type dwarfism (LS) characterized by high circulating levels of serum GH and low levels of insulin like growth factor-1 (IGF-1). We analyzed the GHR gene for genetic defect in seven patients identified as Laron type dwarfism. We identified two missense mutations (S40L and W104R), and four polymorphisms (S473S, L526I, G168G and exon 3 deletion). We are reporting a mutation (W104R) at exon 5 of GHR gene that is not previously reported, and it is a novel mutation.

    Mutations in the growth hormone receptor (GHR) gene can cause growth hormone (GH) resistance. Given the sequence homology between the extracellular domain of the GHR and a soluble GH-binding protein (GH-BP), it is remarkable that GH-BP binding activity is absent from the serum of patients with Laron-type GH insensitivity, a hereditary form of severe dwarfism. We have previously identified a mutation within the extracellular domain of this receptor, replacing phenylalanine by serine at position 96 of the mature protein, in a patient with Laron syndrome. We have now investigated the effect of this Phe----Ser substitution on hormone binding activity by expressing the total human GHR cDNA and mutant form in eukaryotic cells. The wild-type protein expressed was able to bind GH but no plasma membrane binding was detectable on cells transfected with the mutant cDNA; this was also the case of cells transfected with a Phe96----Ala mutant cDNA, suggesting that the lack of binding activity is not due to a posttranslational modification of serine. Examination of the variant proteins in subcellular fractions revealed the presence of specific GH binding activity in the lysosomal fraction, whereas immunofluorescence studies located mutant proteins in the cytosol. Our findings suggest that these mutant GHRs fail to follow the correct intracellular transport pathway and underline the potential importance of this phenylalanine residue, which is conserved among the GH, prolactin, and erythropoietin receptors that belong to the same cytokine receptor superfamily.

    Comparison between the skeletal remains of Homo floresiensis and the auxological and roentgenological findings in a large Israeli cohort of patients with Laron Syndrome (LS, primary or classical GH insensitivity or resistance) revealed striking morphological similarities, including extremely small stature and reduced cranial volume. LS is an autosomal recessive disease caused by a molecular defect of the Growth Hormone (GH) receptor or in the post-receptor cascades. Epidemiological studies have shown that LS occurs more often in consanguineous families and isolates, and it has been described in several countries in South East Asia. It is our conclusion that the findings from the island of Flores, which were attributed to a new species of the genus Homo, may in fact represent a local, highly inbred, Homo sapiens population in whom a mutation for the GH receptor had occurred.

    Laron syndrome (LS, congenital primary GH insensitivity) is caused by deletions or mutations in the GH receptor gene, resulting in an inability to generate insulin-like growth factor-I (IGF-I). If untreated, the deficiency of IGF-I results in severe dwarfism, as well as skeletal and muscular underdevelopment. The only treatment is the daily administration of recombinant IGF-I. This review summarizes the present experience by several groups worldwide. The main conclusions are: A. The one or two injections regimen result in the same growth velocity; B. The growth velocity obtained with IGF-I administration is smaller than that observed with hGH in children with congenital isolated GH deficiency; C. Overdosage of IGF-I causes a series of adverse effects which can be avoided by carefully monitoring the serum IGF-I and GH levels.

    Laron syndrome (LS) or primary GH insensitivity is a unique human model to study the effects of congenital IGF-I deficiency. Within our cohort of 63 patients with LS, 15 female patients were regularly followed since birth or infancy, throughout puberty. We observed that they were short at birth, with small genitalia and gonads -- during puberty, developed delayed puberty but eventually reached between 16 and 19 1/2 years full sexual development. Reproduction is unaffected at a young adult age. It is concluded that IGF-I in concert with the sex hormones has a modulatory but not essential function on female sexual development and maturation.

    Laron syndrome is caused by a mutation in the growth hormone (GH) receptor and manifests as insulin-like growth factor-I (IGF-I) deficiency, severe short stature, and early hypoglycemia. We report a case with postprandial hyperglycemia, an abnormality not reported previously. Postprandial hyperglycemia was due to chronic IGF-I deficiency, and was reversed by IGF-I replacement therapy. A Moroccan girl referred for short stature at 7 years and 8 months of age had dwarfism [height, 78 cm (-9 SDs); weight, 10 kg (-4 SDs)], hypoglycemia, and truncal obesity. Her serum IGF-I level was very low, and her baseline serum GH level was elevated to 47 mIU/l. Molecular analysis showed a homozygous mutation in the GH receptor gene. Continuous glucose monitoring before treatment showed asymptomatic hypoglycemia with postprandial hyperglycemia (2.5 g/l, 13.75 mmol/l). Treatment with recombinant human IGF-I (mecasermin, Increlex®) was started. The blood glucose profile improved with 0.04 µg/kg/day and returned to normal with 0.12 µg/kg/day. Postprandial hyperglycemia is a metabolic consequence of chronic IGF-I deficiency. The beneficial effect of IGF-I replacement therapy may be ascribable to improved postprandial transfer of glucose.

    To quantify body adiposity and its distribution in untreated adult patients with Laron syndrome (LS; primary GH insensitivity) caused by molecular defects of the GH receptor gene or postreceptor pathways and characterized by dwarfism, obesity, insulin resistance and hyperlipidaemia. Eleven LS patients (seven females and four males) aged 28-53 years were studied. Seven healthy males and six healthy females served as controls. Body composition of the total body trunk, upper and lower extremities was determined using dual-energy X-ray absorptiometry (DEXA). Statistical analysis using an analysis of variance (anova) and Mann-Whitney nonparametric methods was performed separately in males and females. Percentage body fat in the LS patients was much higher (P < 0.01) than that in the control population and the female LS patients were significantly more obese (59% total body fat) than the male patients (39% total body fat) (P < 0.002). It was also evident that in these types of patients with markedly increased body fat and decreased muscle and bone mass, body mass index (BMI) does not accurately reflect the body composition. Lifelong congenital IGF-I deficiency leads to extreme adiposity.

    We describe here a 19 month-old girl with classical Laron syndrome (LS). Molecular analysis of the GH receptor gene in the patient and her parents was performed. The patient was found to be heterozygous for a mutation in exon 4 (R43X) and heterozygous for a polymorphism in exon 6 (Gly168Gly). Her mother was also heterozygous for R43X but homozygous for the polymorphism. In the father, a heterozygous polymorphism was found. Contrary to previous assumptions that only homozygous patients express the typical phenotype, this patient shows all the classical features of LS, despite being a heterozygote for a pathological defect.

    The growth hormone (GH)-insulin-like growth factor-1 (IGF1) pathway emerged in recent years as a critical player in cancer biology. Enhanced expression or activation of specific components of the GH-IGF1 axis, including the IGF1 receptor (IGF1R), is consistently associated with a transformed phenotype. Recent epidemiological studies have shown that patients with Laron syndrome (LS), the best-characterized entity among the congenital IGF1 deficiencies, seem to be protected from cancer development. To identify IGF1-dependent genes and signaling pathways associated with cancer protection in LS, we conducted a genome-wide analysis using immortalized lymphoblastoid cells derived from LS patients and healthy controls of the same gender, age range, and ethnic origin. Our analyses identified a collection of genes that are either over- or under-represented in LS-derived lymphoblastoids. Gene differential expression occurs in several gene families, including cell cycle, metabolic control, cytokine-cytokine receptor interaction, Jak-STAT signaling, and PI3K-AKT signaling. Major differences between LS and healthy controls were also noticed in pathways associated with cell cycle distribution, apoptosis, and autophagy. Our results highlight the key role of the GH-IGF1 axis in the initiation and progression of cancer. Furthermore, data are consistent with the concept that homozygous congenital IGF1 deficiency may confer protection against future tumor development. © 2016 Society for Endocrinology.

    Animal and clinical studies have shown that excessive amounts of growth hormone or insulin-like growth factor-I (IGF-I) promote the development of diabetes and diabetic retinopathy. Forthwith, we present two patients with congenital IGF-I deficiency who developed type II diabetes and subsequently retinopathy. Eighteen adult patients with classical Laron syndrome (8 males, 10 females, aged 20-62 years) were followed by us since childhood or underwent fundus photography with a Nikon NF 505 instrument. Three had been treated in childhood with IGF-I, the rest were never treated, including the two patients reported. Two never-treated patients were diagnosed with type II diabetes (DM) at ages 39 and 41 respectively. There was no diabetes in the families. Oral treatment was followed by insulin injections. Metabolic control was not optimal and one patient developed proliferative diabetic retinopathy, necessitating laser surgery. He also has nephropathy and severe neuropathy. The other patient has background diabetic retinopathy and has developed, progressively, exudates, microaneurisms, hemorrhages and clinically significant macular edema. He also has subacute ischemic heart disease. Our findings show that congenital IGF-I deficiency, similar to excess, causes vascular complications of DM, denoting also that vascular endothelial growth factor can induce neovascularization in the presence of congenital IGF-I deficiency.

    Laron Syndrome (LS) represents a condition characterized by GH insensitivity caused by molecular defects in the GH receptor (GHR) gene or in the post-receptor signalling pathway. We report the molecular characterization of two unrelated Italian girls from Sicily diagnosed with LS. The DNA sequencing of the GHR gene revealed the presence of different nonsense mutations, occurring in the same background haplotype. The molecular defects occurred in the extracellular domain of the GHR leading to a premature termination signal and to a truncated non-functional receptor. In one patient, a homozygous G to T transversion, in exon 6, led to the mutation GAA to TAA at codon 180 (E180X), while in the second patient a homozygous C to T transition in exon 7 was detected, causing the CGA to TAA substitution at codon 217 (R217X). Both probands presented the polymorphisms Gly168Gly and Ile544Leu in a homozygous state in exons 6 and 10, respectively. The E180X represents a novel defect of the GHR gene, while the R217X mutation has been previously reported in several patients from different ethnic backgrounds but all from countries located in the Mediterranean and Middle Eastern region.

    Growth hormone (GH) is involved in growth, and fat and carbohydrate metabolism. Interaction of GH with the GH receptor (GHR) is necessary for systemic and local production of insulin-like growth factor-I (IGF-I) which mediates GH actions. Mutations in the GHR cause severe postnatal growth failure; the disorder is an autosomal recessive genetic disease resulting in GH insensitivity, called Laron syndrome. It is characterized by dwarfism with elevated serum GH and low levels of IGF-I. We analyzed the GHR gene for mutations and polymorphisms in eight patients with Laron-type dwarfism from six families. We found three missense mutations (S40L, V125A, I526L), one nonsense mutation (W157X), and one splice site mutation in the extracellular domain of GHR. Furthermore, G168G and exon 3 deletion polymorphisms were detected in patients with Laron syndrome. The splice site mutation, which is a novel mutation, was located at the donor splice site of exon 2/ intron 2 within GHR. Although this mutation changed the highly conserved donor splice site consensus sequence GT to GGT by insertion of a G residue, the intron splicing between exon 2 and exon 3 was detected in the patient. These results imply that the splicing occurs arthe GT site in intron 2, leaving the extra inserted G residue at the end of exon 2, thus changing the open reading frame of GHR resulting in a premature termination codon in exon 3.

    Laron syndrome (LS), known as growth hormone (GH) receptor deficiency, is a rare form of inherited GH resistance. Sleep disorders were described as a common feature of adult LS patients, while no data are available in children. Bi-directional interactions between human sleep and the somatotropic system were previously described, mainly between slow wave sleep and the nocturnal GH surge. To analyze the sleep macro- and microstructure in LS and to evaluate the influence of substitutive insulin-like growth factor 1 (IGF-1) therapy on it. Two young LS females underwent polysomnography; the first study was performed during IGF-1 therapy, the second one after a 3-month wash-out period. In both patients, the sleep macrostructure showed that time in bed, sleep period time, total sleep time, sleep efficiency and rapid eye movement (REM) percentage were all increased during wash-out. The sleep microstructure (cyclic alternating pattern: CAP) showed significantly higher EEG slow oscillations (A1%) in NREM sleep, both during IGF-1 therapy and wash-out. Sleep macrostructure in LS children is slightly affected by substitutive IGF-1 therapy. Sleep microstructure shows an increase of A1%, probably related to abnormally high hypothalamic GHRH secretion, due to GH insensitivity. Copyright 2010 S. Karger AG, Basel.

    There is little information on the relationship between growth hormone/insulin-like growth factor-I (GH/IGF-I) deficiency or IGF-I treatment on nonalcoholic fatty liver disease (NAFLD) a disorder linked to obesity and insulin resistance. To find out whether the markedly obese patients with Laron syndrome (LS) and GH gene deletion have fatty livers. We studied 11 untreated adult patients with LS (5M, 6F), five girls with LS treated by IGF-I and five adult patients with GH gene deletion (3M, 3F), four previously treated by hGH in childhood. Fatty liver was quantitatively evaluated by ultrasonography using a phase array US system (HITACHI 6500, Japan). Body adiposity was determined by DEXA, and insulin resistance was estimated by HOMA-IR using the fasting serum glucose and insulin values. Six out of 11 adult patients with LS, two out of the five IGF-I treated girls with LS and three out of five adult hGH gene deletion patients were found to have NAFLD (nonalcoholic fatty liver disease). NAFLD is a frequent complication in untreated and treated congenital IGF-I deficiency. No correlation between NAFLD and age, sex, degree of obesity, blood lipids, or degree of insulin resistance was observed.

    The type specimen (LB1) of Homo floresiensis has been hypothesized to be a pathological human afflicted with Laron Syndrome (LS), a type of primary growth hormone insensitivity (Hershkovitz et al.: Am J Phys Anthropol 134 [2007] 198-208). Comparing measurements, photographs and three-dimensional, computed-tomography reconstructions of LB1 with data and diagnoses from the literature on LS, we critically evaluate numerous skull and postcranial traits that Hershkovitz et al. identified as being shared by LB1 and patients with LS. The statements regarding most of these traits are new to the clinical literature and lack quantitative support. LB1 and patients with LS differ markedly in the size and shape of the cranium; thickness and pneumatization of cranial bones; morphology of the face, mandible, teeth, and chin; form of the shoulder, wrist, and pelvis; and general body proportions including relative foot size. Claims that patients with LS are similar to LB1 in displaying protracted scapulae, short clavicles, low degrees of humeral torsion, flaring ilia, and curved tibiae are not supported by data or corroborating images. Some points of similarity (e.g., femoral neck-shaft angle, femoral bicondylar angle, and estimated stature) can be found in other hominins, and cannot be considered diagnostic. From our review and analysis, we conclude that LB1 did not suffer from LS. Copyright 2009 Wiley-Liss, Inc.

    Primary IGF-I deficiency (Laron syndrome, LS) may decrease exercise capacity as a result of a lack of an IGF-I effect on heart, peripheral muscle or lung structure and/or function. Eight patients (six females) who had never received treatment with IGF-I, with mean age of 36 +/- 10 (SD) years (range 21-48), weight 47 +/- 9 kg (31-61), height 126 +/- 12 cm (112-140) and body mass index of 29 +/- 4 kg/m2 (24-34), and 12 age-matched controls, underwent lung function tests and incremental cycling to the limit of tolerance (CPX, MedGraphics). Predicted values for the patients were derived from adult equations based on height. In LS patients, lung function was near normal; vital capacity was 84 +/- 11% of expected (66-103). Peak exercise O2-uptake and the anaerobic threshold were reduced, 57 +/- 20% of predicted and 33 +/- 9% of predicted peak (P = 0.005 vs. controls), despite normal mean exercise breathing reserve. All parameters were normal in the controls. Exercise capacity in untreated adults with LS is significantly reduced. The limitation for most patients was not ventilatory but resulted either from low cardiac output and/or from dysfunction of the peripheral muscles. However, the relative contribution of each of these elements and/or the role of poor fitness needs further study.

    Clinical and laboratory investigations of dwarfed children newly Jewish immigrants from Yemen and Middle East and who resembled patients with isolated growth hormone deficiency were started by our group in 1958. In 1963 when we found that they have high serum levels of hGH, we knew that we had discovered a new disease of primary GH insensitivity. It was subsequently coined Laron Syndrome (LS, OMIM #262500). The etiopathogenesis was disclosed by 2 liver biopsies demonstrating a defect in the GH receptor. Subsequent investigations demonstrated deletions or mutations in the GHR gene. The defect lead to an inability of IGF-I generation, resulting in severe dwarfism, obesity, and other morphologic and biochemical pathologies due to IGF-I deficiency. With the biosynthesis of IGF-I in 1986, therapeutic trials started. Following closely our cohort of 69 patients with LS enabled us to study its features in untreated and IGF-I treated patients. This syndrome proved to be a unique model to investigate the effects of IGF-I dissociated from GH stimulation. In recent studies we found that homozygous patients for the GHR mutations are protected lifelong from developing malignancies, opening new directions of research. Copyright © 2015 Elsevier Ltd.

    Out of the 63 patients with Laron Syndrome ( LS) followed in our clinic we were able to perform a genetic analysis on 43 patients belonging to 28 families. Twenty-seven patients were Jews, eight were Arabs, one was Druze, and six were Caucasians from countries other then Israel. Consanguinity was found in 11 families. Molecular analysis of the growth hormone receptor gene was performed in 32 patients and 32 family members. From the study of the pedigrees, as well as the GH receptor gene analysis, we confirmed an earlier report from our group that LS is a recessively inherited disease. One patient with a classical phenotype of LS had a non-classical pattern of inheritance: R43X heterozygosity together with a heterozygous polymorphism G168G; a condition which needs further exploration.

    Serum IGF-I levels were measured in 14 patients (9 children and 5 adults) with Laron syndrome (LS) during long-term treatment by IGF-I. Recombinant IGF-I (FK-780, Fujisawa Pharmaceutical Co. Ltd., Japan) was administered once daily subcutaneously before breakfast for 3-5 years to the children and for 9 months to the adults. The initial daily dose was 150 micrograms/kg for children and 120 micrograms/kg for adults. Before initiation of treatment the mean overnight fasting levels of serum IGF-I in the children was 3.2 +/- 0.8 nmol/l (mean +/- SEM), rising to 10 +/- 1.7 nmol/l during long-term treatment even on a dose of 120 micrograms/kg/day. The serum IGF-I levels 4 hours after injection rose from 31.2 +/- 3.5 to 48 +/- 2 nmol/l. In the adult patients, the initial basal IGF-I was 4.1 +/- 0.7 nmol/l, rising to 16.1 +/- 3.84 nmol/l after 8-9 months treatment. Serum IGF-I levels at 4 hours after injection rose in the adult patients from 24.1 +/- 5.8 up to 66.8 +/- 15.4 nmol/l. A progressively increasing half-life during long term exogenous administration of IGF-I to patients with Laron syndrome was demonstrated by following serum IGF-I dynamics after injection. Based on the fact that no antibodies to IGF-I were detected and on findings in previous studies, it is speculated that the increasing serum IGF-I levels during long-term IGF-I treatment are caused by an increase in serum IGFBP-3 induced by chronic IGF-I administration. It is concluded that treatment with IGF-I necessitates regular monitoring of serum IGF-I levels; in patients in whom the age adjusted maximal levels are exceeded, a reduction of the daily IGF-I dose is indicated to avoid undesirable effects.

    Patients with primary growth hormone (GH) resistance-Laron Syndrome (LS)-have no GH signal transmission, and thus, no generation of circulating insulin-like growth factor-I (IGF-I), and should serve as a unique model to explore the controversies concerning the longterm effect of GH/IGF-I deficiency on cardiac dimension and function. We assessed 8 patients with LS (4 men, 4 women) with a mean (+/- SD) age of 38+/-7 years (range 22 to 45), and 8 aged-matched controls (4 men, 4 women) with a mean age of 38+/-9 years (range 18 to 47) by echocardiography at rest, following exercise, and during dobutamine administration. Left ventricular (LV) septum, posterior wall, and end-diastolic diameter were significantly reduced in untreated patients with LS compared with the control group (p<0.05 for all). Systolic Doppler-derived parameters, including LV stroke volume, stroke index, cardiac output, and cardiac index, were significantly lower (p<0.05 for all) than in the control subjects, whereas LV diastolic Doppler parameters, including mitral valve waves E, A, E/A ratio, and E deceleration time, were similar in both groups. LV ejection fraction at rest as well as the stress-induced increment of the LV ejection fraction were similar in both groups. Our results show that untreated patients with long-term IGF-I deficiency have reduced cardiac dimensions and output but normal LV ejection fraction at rest and LV contractile reserve following stress.

    To analyze clinical manifestations and gene mutations in a child with severe short stature, explore its molecular mechanism and further clarify the diagnostic procedure for short stature. We observed clinical characteristics of a patient with short stature and did diagnostic examinations, assessed the function of GH-IGF-1 axis, and surveyed its family members.Genomic DNA was extracted from peripheral blood, GHR, IGFALS, STAT5b and GH1 gene were amplified by PCR for sequencing, including exons and splicing areas. The patient presented symmetrical short stature (height -8.2 SDS) and facial features, and other congenital abnormalities.It displayed non-growth hormone deficiency. The baseline value of GH was 21 µg/L, and the peak was 57.9 µg/L. The value of IGF-1 was less than 25 µg/L, and the IGFBP-3 less than 50 µg/L. And IGF-1 generation test showed no response. There was no similar patients in the family members.Sequencing of GHR in the patient revealed a homozygous point mutation (c.Ivs6+1G>A), and her father and mother had the same heterozygous mutation. The same mutation was not identified for her sister.No other candidate gene was found. As the result of combined clinical characteristics and lab examinations, as well as gene detection, the case was diagnosed with Laron syndrome and GHR gene mutation is the molecular mechanism.We should explicit the etiological diagnosis for short stature, and avoid missed diagnosis and misdiagnosis.

    Laron syndrome (LS), which can be defined as primary growth hormone resistance or insensitivity, is a rare genetic disease inherited by an autosomal recessive trait. Although it is undistinguishable from growth hormone deficiency, LS has high levels of growth hormone, but insulin-like growth factor (IGF-1) cannot be synthesized. Mecasermin treatment is the only option for the patients who suffer from LS. This study aims to research cardiac findings of children with LS, who receive treatment with mecasermin. The study enrolled five children four males and one female, 4 M/1 F with LS, two of whom were siblings with a mean age of 6.3±2.1 years, a body weight of 13.36±4.74 kg, a height of 88±8.7 cm, and a body mass index (BMI) of 16.47±3.35. Their demographic data were obtained from their family and files. The children received mecasermin via subcutaneous injection at 0.04-0.12 μg/kg doses twice per day. The duration of mecasermin treatment was 8-53 months. All of them were examined clinically by electrocardiogram and echocardiogram. Their cardiac examinations were normal, except for one case, who had systolic murmur at cardiac auscultation. Arrhythmia was not observed on their electrocardiograms. The echocardiograms did not show a significant congenital cardiac anomaly. Their cardiac measure and functions were within normal ranges. The echocardiogram of the child with the murmur showed mitral and tricuspid insufficiency. The Doppler images showed pulmonary hypertension findings. These findings were proven by angiography. The vasoreactivity test results of that patient were negative. No reason could be found for the observed pulmonary hypertension. We diagnosed this finding as a primary pulmonary hypertension and Bosentan therapy was started. In this study, we showed that cardiac findings were consistent with previous studies. To the best of our knowledge, the observed pulmonary hypertension in children with LS, who received treatment with or without mecasermin

    Laron syndrome (LS) is an autosomal recessive disease characterized by marked short stature and very low serum IGF-1 and IGFBP-3 levels. This study assessed the clinical and endocrine features alongside determining the growth hormone receptor gene (GHR) mutation in Saudi Arabian patients with LS in order to establish whether or not a genotype/phenotype correlation is evident in this large cohort. A total of 40 Saudi Arabian patients with a suspected diagnosis of LS were recruited and subjected to a full clinical and endocrine investigation together with direct sequencing of the coding regions of the GHR gene. GHR mutations were identified in 34 patients from 22 separate nuclear families. All 34 molecularly confirmed patients had the typical clinical and endocrinological manifestations of LS. Eleven different mutations (9 previously unreported) were detected in this cohort of patients, all inherited in an autosomal recessive homozygous form. No genotype/phenotype correlation was apparent. The identification of pathogenic mutations causing LS will be of tremendous use for the molecular diagnosis of patients in Saudi Arabia and the region in general, with respect to prevention of this disease in the forms of future carrier testing, prenatal testing, premarital screening and preimplantation genetic diagnosis. © 2017 S.

    In addition to its classical effects on growth, growth hormone (GH) has been shown to have a number of other actions, all of which are initiated by an interaction with specific high affinity receptors present in a variety of tissues. Purification of a rabbit liver protein via its ability to bind GH has allowed the isolation of a cDNA encoding a putative human growth hormone receptor that belongs to a new class of transmembrane receptors. We have previously shown that this putative growth hormone receptor gene is genetically linked to Laron dwarfism, a rare autosomal recessive syndrome caused by target resistance to GH. Nevertheless, the inability to express the corresponding full-length coding sequence and the lack of a test for growth-promoting function have hampered a direct confirmation of its role in growth. We have now identified three nonsense mutations within this growth hormone receptor gene, lying at positions corresponding to the amino terminal extremity and causing a truncation of the molecule, thereby deleting a large portion of both the GH binding domain and the full transmembrane and intracellular domains. Three independent patients with Laron dwarfism born of consanguineous parents were homozygous for these defects. Two defects were identical and consisted of a CG to TG transition. Not only do these results confirm the growth-promoting activity of this receptor but they also suggest that CpG doublets may represent hot spots for mutations in the growth hormone receptor gene that are responsible for hereditary dwarfism.

    Full Text Available Objective: Laron syndrome (LS is a rare, autosomal recessive disorder in humans caused by loss-of-function mutations of the growth hormone receptor (GHR gene. To establish a large animal model for LS, pigs with GHR knockout (KO mutations were generated and characterized. Methods: CRISPR/Cas9 technology was applied to mutate exon 3 of the GHR gene in porcine zygotes. Two heterozygous founder sows with a 1-bp or 7-bp insertion in GHR exon 3 were obtained, and their heterozygous F1 offspring were intercrossed to produce GHR-KO, heterozygous GHR mutant, and wild-type pigs. Since the latter two groups were not significantly different in any parameter investigated, they were pooled as the GHR expressing control group. The characterization program included body and organ growth, body composition, endocrine and clinical-chemical parameters, as well as signaling studies in liver tissue. Results: GHR-KO pigs lacked GHR and had markedly reduced serum insulin-like growth factor 1 (IGF1 levels and reduced IGF-binding protein 3 (IGFBP3 activity but increased IGFBP2 levels. Serum GH concentrations were significantly elevated compared with control pigs. GHR-KO pigs had a normal birth weight. Growth retardation became significant at the age of five weeks. At the age of six months, the body weight of GHR-KO pigs was reduced by 60% compared with controls. Most organ weights of GHR-KO pigs were reduced proportionally to body weight. However, the weights of liver, kidneys, and heart were disproportionately reduced, while the relative brain weight was almost doubled. GHR-KO pigs had a markedly increased percentage of total body fat relative to body weight and displayed transient juvenile hypoglycemia along with decreased serum triglyceride and cholesterol levels. Analysis of insulin receptor related signaling in the liver of adult fasted pigs revealed increased phosphorylation of IRS1 and PI3K. In agreement with the loss of GHR, phosphorylation of STAT5 was

    Severe short stature resulting from a deficiency in insulin-like growth factor-I (IGF-I) is a prominent feature of Laron syndrome (LS). Whether patients with LS are osteopenic or not, and whether they need treatment with bisphosphonates, remains uncertain. The aim of this study was to investigate the action of alendronate on the IGF-I-deficient bones of adult patients with LS and osteoporosis, as determined by dual X-ray absorptiometry . Seven patients (5 women and 2 men) of mean age 40.8+/-7.6 years and mean bone mass density (BMD) 0.843+/-0.06 g/cm2 (T score -2.9+/-0.5) at the lumbar spine and 0.734+/-0.11 g/cm2 (T score -2.2+/-0.9) at the femoral neck were treated with alendronate 70 mg once/weekly over a 12-month period. Treatment led to an increase of 5.3% in BMD (p=0.038) at the femoral neck. There was a similar trend at the lumbar spine, but the difference was not statistically significant (2.3%, p=0.34). Mean total alkaline phosphatase decreased by 14% from normal range at baseline (p=0.007). Urinary deoxypyridinoline levels, which were elevated at baseline (10+/-2.3 nM/mMcre), showed a nonsignificant change during treatment. Our study suggests that treatment with alendronate may have positive effects in patients with LS and low BMD on dual X-ray absorptiometry.

    Classic Laron Syndrome (LS) is a recessive disease of insulin-like growth factor I (IGF-I) deficiency and primary growth hormone insensitivity, clinically characterized by dwarfism and marked obesity. The aim of the current study was to investigate the impact of long-term IGF-I deficiency on flow-mediated dilation (FMD) in 11 non-IGF-I-treated LS adults with long-term IGF-I deficiency who on stress echocardiography were found to have reduced cardiac dimensions and output, but normal left ventricular (LV) ejection fraction at rest and LV contractile reserve following stress. Following an overnight fast we assessed percent improvement in endothelium-dependent FMD (%FMD) and endothelium-independent nitroglycerin (%NTG)-mediated vasodilation non-invasively in the brachial artery, using high resolution ultrasound in 11 non-treated adult patients with LS without known coronary artery disease, and compared them to 11 age- and sex-matched healthy controls. All subjects underwent symptom-limited exercise testing (Bruce protocol). LS patients had a significantly higher body mass index (29+/-6 vs. 25+/-2 kg/m(2), p=0.04), lower low-density lipoprotein cholesterol (142+/-28 vs. 176+/-12 mg/dl, p=0.03) and a smaller mean brachial artery diameter (4.63+/-0.72 vs. 5.70+/-1.06 mm, p=0.01) compared to controls. However, brachial artery %FMD and %NTG were not significantly different between the LS patients and controls (13.1+/-6.2% vs. 15.4+/-5.2%, p=0.28 and 22.3+/-6.0% vs. 18.9+/-6.2%, p=0.30; respectively). Cardiac performance, assessed by exercise duration time and metabolic equivalents (METs), was significantly greater in control subjects than in LS patients (10.3+/-2.0 vs. 6.0+/-1.4 min, p<0.01 and 10.2+/-2.0 vs. 7.2+/-1.4 METs, p<0.01; respectively). FMD was found to be within normal limits in non-IGF-I-treated adult patients with LS, despite congenital absence of IGF-I and obesity.

    Patients with Laron syndrome (LS; primary GH insensitivity) caused by molecular defects of the GH receptor gene, are characterized by dwarfism, profound obesity, and hyperlipidemia. The aim of the current study was to evaluate adiponectin levels in LS, as obesity is known to be associated with low adiponectin. We studied nine untreated LS adult patients (5 males, 4 females) and six girls with LS receiving once-daily treatment by IGF1. Total and high molecular weight (HMW) adiponectin levels, adiponectin multimers distribution, and metabolic indices were analyzed in serum samples obtained during several years of follow-up. Adiponectin levels in the severely obese adult LS patients (percent body fat; females 61.0+/-2.5%, males 40.6+/-8.1%) were two- to three-fold higher than those reported for subjects of corresponding age, gender and degree of adiposity. Total adiponectin was significantly higher in females compared with males (21.4+/-3.5 vs 10.2+/-4.6 microg/ml, P<0.001). The elevated adiponectin in LS subjects was associated with an increased abundance of the HMW isoform, and positively correlated with body fat percentage (r=0.65, P=0.017) and leptin (r=0.65, P=0.012). There was no correlation between adiponectin levels (total and HMW) and the degree of insulin resistance in LS subjects or their blood lipids levels. Adiponectin was also high in young girls with LS (22.9+/-7.4 microg/ml) and did not change during long-term IGF1 replacement therapy. Adiponectin hypersecretion in LS, despite profound obesity, suggests that GH activity may negatively impact adiponectin secretion from adipocytes.

    Laron syndrome (LS), or primary growth hormone (GH) insensitivity, is a growth disorder that results from mutation of the GH-receptor (GHR) gene leading to congenital insulin-like growth factor-1 (IGF-1) deficiency. Recent epidemiological studies have shown that LS patients are protected from cancer development. Genome-wide profiling identified genes and signaling pathways that are differentially represented in LS patients, and that may contribute to cancer protection. The present study was aimed at evaluating the hypothesis that IGF binding proteins (IGFBPs) are differentially expressed in LS, most probably as a result of low circulating levels of IGF-1. Furthermore, we postulated that IGFBPs might be differentially regulated by oxidative stress in this condition and, therefore, may contribute to cancer evasion. Our results show that IGFBP-3, which is predominantly protective, was highly expressed in LS-derived lymphoblastoid cells in comparison to control cells from the same ethnic group. On the other hand, levels of IGFBP-2, -4, -5, and -6 were diminished in LS patients, as demonstrated by RQ-PCR, Western immunoblots and confocal immunofluorescence. In addition, our data provide evidence for a pattern of IGFBP response to H 2 O 2 treatment that might be associated with distinct expression of apoptosis markers (BCL2, pro-caspase-9, pro-caspase-3) in LS. In summary, differential expression of specific IGFBPs in LS might be correlated with cellular mechanisms underlying cancer protection and, probably, additional phenotypes due to congenital IGF-1 deficiency.

    Full Text Available Primary growth hormone insensitivity syndrome (GHIS is a rare entity which can be due to defects in growth hormone (GH receptor that is called type 1 Laron syndrome (T1LS or post receptor defects (type 2 Laron syndrome . The aim of study was determining the clinical and hormonal milieu of the patients with primary GHIS and their response to IGF-I (insulin like growth factor-I generation test (IGT. GH, IGF-I, IGF-II, IGF binding protein 1 and 3 (BP-1 and BP-3, GH binding protein (GHBP and anti-GH antibody were detected by ELISA and RIA methods. IGF-I and BP-3 were measured before and after IGT. Nine patients (8 males, 1 female (mean age ± SD, 6.4 ± 5 years with severe short stature and high GH level were studied. Height SDS was - 8.5 ± 2.6. In 7 patients GHBP was zero, IGF-I and BP-3 were low and did not increase after IGT, so they had T1LS. Two brothers did not show the hormonal milieu of GH receptor defect, and were called non Laron syndrome (NLS. Birth weight in patients with T1LS and NLS was 3.65 ± 0.2 Kg and 1.65 ± 0.2 Kg, respectively (P = 0.001. All of the patients had typical clinical feature of GH-deficiency, but nasal bridge depression and microphallus were not seen in NLS. GH treatment of NLS, normalized their growth velocity, but without catch up growth. In conclusion IGT can differentiate Laron syndrome from other types of short stature. GH and IGF-I of fetus have no role in intrauterine growth.

    A single point mutation in the growth hormone (GH) receptor gene generating a Phe-->Ser substitution in the extracellular binding domain of the receptor has been identified in one family with Laron type dwarfism. The mutation was introduced by site-directed mutagenesis into cDNAs encoding the full-length rabbit GH receptor and the extracellular domain or binding protein (BP) of the human and rabbit GH receptor, and also in cDNAs encoding the full length and the extracellular domain of the related rabbit prolactin (PRL) receptor. All constructs were transiently expressed in COS-7 cells. Both wild type and mutant full-length rabbit GH and PRL receptors, as well as GH and prolactin BPs (wild type and mutant), were detected by Western blot in cell membranes and concentrated culture media, respectively. Immunofluorescence studies showed that wild type and mutant full-length GH receptors had the same cell surface and intracellular distribution and were expressed with comparable intensities. In contrast, all mutant forms (full-length receptors or BPs), completely lost their modify the synthesis ligand. These results clearly demonstrate that this point mutation (patients with Laron syndrome) does not modify the synthesis or the intracellular pathway of receptor proteins, but rather abolishes ability of the receptor or BP to bind GH and is thus responsible for the extreme GH resistance in these patients.

    The correlation between the molecular defects of the GH receptor (R), psychosocial development and brain abnormalities were evaluated in 10 patients with Laron syndrome (LS), in whom all data were available. The findings revealed that the intelligence quotient (IQ) and abnormalities in the brain of the patients with LS differ with various molecular defects of the GH-receptor. The most severe mental deficits and brain pathology occurred in patients with 3, 5, 6 exon deletion. Patients with point mutations in exons 2, 4 and 7 presented various degrees of medium to mild CNS abnormalities that correlated with the IQ. Notably, the patient with the E180 splice mutation in exon 6 had a normal IQ, which fits the report on normal IQ in a large Ecuadorian cohort with the same mutation. This is the first report to support a correlation between IQ, brain abnormalities and localization of the molecular defects in the GH-R gene. As all patients with LS are IGF-I-deficient, it must be assumed that other as yet unknown factors related to the molecular defects in the GH-R are the major cause of the differences in intellect and brain abnormalities.

    To evaluate the ocular dimensions in patients with primary growth hormone receptor insensitivity (Laron syndrome [LS]) and to study the effect of supplemental insulinlike growth factor I (IGF-I) on ocular growth. Retrospective case series. Twelve patients with LS, 8 untreated (LS group) and 4 treated (LS-T group) with supplemental IGF-I, and 30 healthy controls. Ocular dimensions and refraction were measured, and a full ophthalmologic examination was performed. Differences in the average ocular dimension data among IGF-I-treated patients, untreated ones, and controls. The average axial length of eyes in the LS group was 21.94 mm (standard deviation [SD], 0.81). Corresponding values for the LS-T and control group eyes were 22.53 mm (SD, 1.74) and 23.20 mm (SD, 1.35) respectively. The average anterior chamber depth of eyes in the LS group was 2.55 mm (SD, 0.26). Corresponding values for eyes in the LS-T and control groups were 3.48 mm (SD, 0.09) and 3.84 mm (SD, 0.16) respectively. The average lens thickness of eyes in the LS group was 4.56 mm (SD, 0.36). Corresponding values for the LS-T and control groups were 3.77 mm (SD, 0.23) and 3.51 mm (SD, 0.25), respectively. The average corneal curvature of eyes in the LS group was 46.9 diopters (D) (SD, 2.32). Corresponding values for the LS-T and control groups were 47.6 D (SD, 2.83) and 44.4 D (SD, 1.5), respectively. Insulinlike growth factor I seems to be an important regulator of ocular growth as documented in patients with primary growth hormone insensitivity. The mechanism of this observation should be investigated further.

    Severe short stature resulting from a deficiency in IGF-I is a prominent feature of Laron syndrome (LS). Although low bone mineral density (BMD) has been noted in LS patients examined by dual energy x-ray absorptiometry (DEXA), this technique does not take volume into account and may therefore underestimate the true bone density in patients with small bones. The aim of the present study was to evaluate the BMD yielded by DEXA in our LS patients using estimated volumetric values. Volumetric density was calculated with the following formulas: bone mineral apparent density (BMAD) = bone mineral content (BMC)/(area)(3/2) for the lumbar spine and BMAD = BMC/area(2) for the femoral neck. The study sample included 12 patients (mean age, 43.9 yr; mean height, 123.7 cm). Findings were compared with 10 osteopenic subjects without developmental abnormalities (mean age, 56 yr; mean height, 164.8 cm) and 10 healthy control subjects matched for sex and age to the LS patients (mean height, 165.5 cm). BMAD in the LS group was 0.201 +/- 0.02 g/cm(3) at the lumbar spine and 0.201 +/- 0.04 g/cm(3) at the femoral neck; corresponding values for the osteopenic group were 0.130 +/- 0.01 and 0.140 +/- 0.01 g/cm(3), and for the controls, 0.178 +/- 0.03 and 0.192 +/- 0.02 g/cm(3). Although areal BMD was significantly lower in the LS and osteopenic subjects compared with controls (P < 0.02) at both the lumbar spine and femoral neck, BMAD was low (P < 0.01) in the osteopenic group only. In conclusion, DEXA does not seem to be a reliable measure of osteoporosis in patients with LS.

    Primary insulin-like growth factor-I (IGF-I) deficiencies, such as in Laron syndrome (LS), are a unique model in man to study the consequences resulting from defects in growth hormone (GH) signal transmission. To assess retrospectively the effect of IGF-I deficiency and its therapy on the various cells of the hematopoietic system as reflected by peripheral blood counts. Two groups of patients were studied. The first group consisted of 11 untreated patients with LS, seven males and four females, who were followed from childhood into adult age. Average age at the time of data analysis was 45.4 +/- 9.6 years. The second group included ten children with LS, six males and four females, who received IGF-I replacement therapy for an average period of 6 years, ranging in age from 0.9-11 years. The mean age at initiation of therapy was 6.9 +/- 4.28 years. Only the seven children treated for 5 years or more were included in the analysis. Data on blood counts were collected from the patients' charts. Blood samples were drawn at baseline, weekly during the first month, once a month during the first year, and once every 3 months thereafter. Statistical analysis of the change over time was performed using repeated measures ANOVA. Children with LS had red cell indices in the lower normal range and an elevated monocyte count. A statistically significant rise in red blood cell (RBC) indices was seen in children during IGF-I therapy: RBC rose from 4.66 x 10(6)/ml to 4.93 x 10(6)/ml (p = 0.011); hemoglobin from 11.55 g/dl to 13.01 g/dl (p syndrome, confirms that IGF-I has a strong stimulatory effect on erythropoiesis. In addition, IGF-I therapy had a reducing effect on monocytes and platelets, an effect not previously described. The mechanism by which IGF-I mediates these effects needs further elucidation.

    Head circumference (HC) is a simple and practical measure of brain size, development and longitudinal measurements of the HC in childhood are an index of brain growth. To determine the effects of long IGF-I deficiency and treatment on HC in patients with Laron syndrome (LS). 20 untreated adult LS patients, aged 48.4±11.2 years and 13 LS patients treated between ages of 5.6±4 to 11.3±3 years were studied. 15 patients with congenital IGHD treated between age 6.1±4 and 13±4 by hGH served as controls. HC was expressed as standard deviation (SD) and Ht as SDS. HC was measured and plotted on Nellhaus charts. Linear height (Ht) was measured by a Harpenden Stadiometer. The mean HC deficit of the adult untreated LS males was -2.9±0.6 SD compared to a Ht deficit of -7.0±1.7 SDS. The HC of the LS adult females was -3.6±1 SD compared to a Ht SDS of -6.9±1.5 (pdeficit decreased only by 1.5 SDS. hGH treatment of cIGHD children increased the HC from -2.0±1.8 to 0.3±1.2 SD and the Ht SDS from -4.8±1.6 to 1.6±1.0.

    To evaluate changes in adiposity in congenital GH/IGF-1 deficient children during hGH or IGF-1 treatment. 27 children with congenital isolated growth hormone deficiency (cIGHD) treated with hGH for 2.5-€“15.2 years (mean 10.0 ± 3.4), 18 children with congenital multiple pituitary hormone deficiency (cMPHD), treated with hGH for 2.3-€“17.9 years (mean 6.1 ± 4.3), and 14 children with Laron syndrome (LS) treated with IGF-1 for 1.2-12 years (mean 5.5 ± 3.7) were studied. Changes in the degree of adiposity were evaluated by subscapular skinfold thickness (SSFT), before, during and up to 2 years after treatment. All the children had various degrees of obesity. During the pretreatment period, cIGHD patients showed little changes in SSFT (P = 0.45), cMPHD and LS patients showed an increase in SSFT (P = 0.01, P = 0.06 respectively). During the initial 0.6-1.1 years of hGH/IGF-1 treatment, the SSFT decreased in all 3 groups (P < 0.001), while during subsequent years a significant increase in SSFT (P < 0.001) was observed, in all types of patients, notably in females. Only the cIGHD patients demonstrated a significant correlation between the degree of SSFT decrease and height SDS gain (R = -ˆ’0.56, P = 0.002) in the first period of treatment. Short term replacement therapy of 0.6-€“1.1 years with either hGH or IGF-1, induced a reduction in subscapular subcutaneous fat whereas prolongation of therapy led to an increase in the subcutaneous fat. © 2014 Asian Oceanian Association for the Study of Obesity .

    To compare foot length deficits between patients with Laron syndrome (LS) (primary growth hormone [GH] insensitivity) and congenital isolated GH deficiency (IGHD) and their response to replacement therapy with insulin-like growth factor-I (IGF-I) and hGH, respectively. Data for the study were collected from the records of nine children with LS (3 M, 6 F) 7.8 +/- 4.8 years old (mean +/- SD), and nine children with IGHD (3 M, 6 F), 3.8 +/- 3.3 years old. Fifteen non-treated adult patients with LS were also included in the study. Measurements of foot length were recorded without treatment and monitored during 9 years of treatment in the children and in the untreated adult patients. For statistical analysis the non-parametric Mann-Whitney U test was used. With almost similar basal values in growth deficit and pre-treatment growth velocities, the achievements towards norms after 9 years of treatment were greater in the patients with IGHD than in the patients with LS: foot length reached -1.4 +/- 0.8 vs. -3.3 +/- 1.0 SDS (mean +/- SD), and body height -2.2 +/- 1.0 vs. -3.9 +/- 0.5 SDS. The difference between the two groups could be due to the initiation of replacement therapy in the patients with IGHD at a younger age. Adult foot size of untreated patients with LS is small but less retarded than the height deficit. Both IGF-I and hGH are potent growth stimulating hormones of linear growth and acrae as exemplified by foot growth.

    Growth hormone (GH) elicits a variety of biological activities mainly mediated by the GH receptor (GHR), a transmembrane protein that, based on in vitro studies, seemed to function as a homodimer. To test this hypothesis directly, we investigated patients displaying the classic features of Laron syndrome (familial GH resistance characterized by severe dwarfism and metabolic dysfunction), except for the presence of normal binding activity of the plasma GH-binding protein, a molecule that derives from the exoplasmic-coding domain of the GHR gene. In two unrelated families, the same GHR mutation was identified, resulting in the substitution of a highly conserved aspartate residue by histidine at position 152 (D152H) of the exoplasmic domain, within the postulated interface sequence involved in homodimerization. The recombinant mutated receptor protein was correctly expressed at the plasma membrane. It displayed subnormal GH-binding activity, a finding in agreement with the X-ray crystal structure data inferring this aspartate residue outside the GH-binding domain. However, mAb-based studies suggested the critical role of aspartate 152 in the proper folding of the interface area. We show that a recombinant soluble form of the mutant receptor is unable to dimerize, the D152H substitution also preventing the formation of heterodimers of wild-type and mutant molecules. These results provide in vivo evidence that monomeric receptors are inactive and that receptor dimerization is involved in the primary signalling of the GH-associated growth-promoting and metabolic actions.

    Laron syndrome (LS) is a genetic disorder caused by mutations in the growth hormone receptor (GHR) gene. The most frequent GHR mutation is E180splice (rs121909360), which was initially found in an inbred population of Spanish descent in Ecuador and subsequently in Israel, Brazil, Chile, and the United States. The aim of the present study is to determine if the E180splice mutation arose from a common origin. We studied 22 patients with LS from Ecuador, Israel (of Moroccan origin), Brazil, Chile, and the United States (of Mexican origin) who were homozygous for the E180splice mutation and compared them to control individuals for markers surrounding the GHR, intragenic polymorphisms, and Y-chromosome STR. An identical haplotype was found in all but one of the subjects carrying the E180splice mutation: D5S665: 150/150; D5S2082: 192/192; D5S2087: 246/246; rs6179 G/G; and rs6180 C/C. One patient differed from the others only at D5S2082 (168/192). This haplotype is rare (~1%) in control individuals and confirmed that the E180splice-associated haplotype was not derived from independent origins but represented recombination from a common ancestor. The analysis of paternal lineage markers showed that 50% belong to haplogroup R1b (found in Portugal and Spain) and 40% to haplogroups J and E (typical in the Middle East and in Eastern European Jews). The germline E180Splice mutation appears to have originated from a single common ancestor. The presence of Y-chromosome markers associated with Sephardic populations in persons harboring the E180splice mutation provides genetic evidence in support of the historical tracking of the exodus of this specific population. © 2014 Wiley Periodicals, Inc.

    Herein, we present a 14-year-old patient with short stature (134 cm) referred from Paediatrics to our department for complementary evaluation since growth hormone (GH) treatment failed to show any improvement. He was born premature and small for gestational age. Genital examination classified the patient as Tanner I–II with small penis and testicular size for his age. Biochemical analyses revealed normal GH levels with low serum insulin-like growth factor-1 (IGF-1). Molecular diagnosis confirmed several mutations in IGF1R and IGFALS, and so he was diagnosed with Laron Syndrome or GH insensibility and treated with IGF-1 substitutive therapy. Learning points: Evaluation of the GH/IGF-1 axis when short stature does not respond to conservative treatment must be included in the ordinary practice. Laron Syndrome real incidence should be calculated once undiagnosed cases arise, as treatment, due to lack of market, is unaffordable. Even when adulthood is reached, and no longitudinal growth can be achieved, still IGF-1 treatment in Laron Syndrome patients should be pursued as metabolic and protective derangements could arise.

    It has recently been recognized that human serum contains a protein that specifically binds human growth hormone (hGH). This protein has the same restricted specificity for hGH as the membrane-bound GH receptor. To determine whether the GH-binding protein is a derivative of, or otherwise related to, the GH receptor, the authors have examined the serum of three patients with Laron-type dwarfism, a condition in which GH refractoriness has been attributed to a defect in the GH receptor. The binding of /sup 125/I-labeled hGH incubated with serum has been measured after gel filtration of the serum through an Ultrogel AcA 44 minicolumn. Results are expressed as percent of specifically bound /sup 125/I-hGH and as specific binding relative to that of a reference serum after correction is made for endogenous GH. The mean +/- SEM of specific binding of sera from eight normal adults (26-46 years of age) was 21.6 +/- 0.45%, and the relative specific binding was 101.1 +/- 8.6%. Sera from 11 normal children had lower specific binding of 12.5 +/- 1.95% and relative specific binding of 56.6 +/- 9.1%. Sera from three children with Laron-type dwarfism lacked any demonstrable GH binding, whereas sera from 10 other children with other types of nonpituitary short stature had normal relative specific binding. They suggest that the serum GH-binding protein is a soluble derivative of the GH receptor. Measurement of the serum GH-binding protein may permit recognition of other abnormalities of the GH receptor.

    GH-IGF-I axis is mainly involved in the complex process of somatic growth but emerging evidence suggests that it also influences hypothalamic-pituitary-gonadal (HPG) function. We report some data regarding long-term auxological and pubertal outcome of five female patients with hereditary forms of GH-IGF-I deficiency (Laron and GH-gene deletion syndrome) and a mean age of 23.4±5.3 yr (range 19-32). All the patients received recombinant human IGF-I (rhIGF-I, Pharmacia and Upjohn, Stockholm, Sweden, and rhIGF-I, Genentech, San Francisco, CA, USA) from a mean age of 8.6 yr (range 3.2-14.2) up to the final height. Final height was very disappointing (≤ -5.0 SD scores) and lower than target height in all the patients. Pubertal onset was delayed in most of them but menarche occurred spontaneously in all the patients. Median age at menarche was 15.1 yr. Menstrual cycles were regular for several years. Median duration of gynecological follow- up was 8.3 yr with the longest span of 17.2 yr. We can assert that GH-IGF-I axis has an essential role in promoting linear growth in humans and its physiological action cannot be replaced by pharmacological treatment in most patients with hereditary forms of IGF-I insufficiency as demonstrated by their subnormal final height. Our clinical observations can also support an essential role of IGF-I in genitalia growth but not in the function of HPG axis as demonstrated by the maintenance of regular menstrual cycles in the presence of subnormal levels of IGF-I after treatment discontinuation.

    Laron syndrome (LS) is a rare, autosomal recessive disorder in humans caused by loss-of-function mutations of the growth hormone receptor (GHR) gene. To establish a large animal model for LS, pigs with GHR knockout (KO) mutations were generated and characterized. CRISPR/Cas9 technology was applied to mutate exon 3 of the GHR gene in porcine zygotes. Two heterozygous founder sows with a 1-bp or 7-bp insertion in GHR exon 3 were obtained, and their heterozygous F1 offspring were intercrossed to produce GHR-KO, heterozygous GHR mutant, and wild-type pigs. Since the latter two groups were not significantly different in any parameter investigated, they were pooled as the GHR expressing control group. The characterization program included body and organ growth, body composition, endocrine and clinical-chemical parameters, as well as signaling studies in liver tissue. GHR-KO pigs lacked GHR and had markedly reduced serum insulin-like growth factor 1 (IGF1) levels and reduced IGF-binding protein 3 (IGFBP3) activity but increased IGFBP2 levels. Serum GH concentrations were significantly elevated compared with control pigs. GHR-KO pigs had a normal birth weight. Growth retardation became significant at the age of five weeks. At the age of six months, the body weight of GHR-KO pigs was reduced by 60% compared with controls. Most organ weights of GHR-KO pigs were reduced proportionally to body weight. However, the weights of liver, kidneys, and heart were disproportionately reduced, while the relative brain weight was almost doubled. GHR-KO pigs had a markedly increased percentage of total body fat relative to body weight and displayed transient juvenile hypoglycemia along with decreased serum triglyceride and cholesterol levels. Analysis of insulin receptor related signaling in the liver of adult fasted pigs revealed increased phosphorylation of IRS1 and PI3K. In agreement with the loss of GHR, phosphorylation of STAT5 was significantly reduced. In contrast, phosphorylation

    In a child with short stature, the finding of normal or elevated GH levels in the presence of low concentrations of IGF-I raises the following possibilities. (1) A modification of the GH molecule, which is still detected by RIA, but inactive biologically. Therefore, an RRA or bioassay for hGH should result in considerably lower GH measurements compared with RIA determinations in the same sample. As both bioassays as well as RRAs are not widely available and are hampered by several difficulties, few children with this presumptive diagnosis have been described. So far, it has not been possible to define a specific molecular defect in one of these patients. (2) Abnormalities of the GH receptor or postreceptor mechanisms lead to a GH insensitivity syndrome. Laron-type dwarfism is usually due to a deletion in the gene for hepatic GH receptors: the serum binding protein for GH is absent. In three additional populations, the Pygmies of Zaire, the little women of Loja in Ecuador and the Mountain Ok people in Papua New Guinea, alterations of GH receptor function have been described. Finally, some reports describe patients with normal or elevated serum levels of both growth hormone and IGF-I in whom resistance to IGF has been implied in the pathogenesis of small stature.

    By definition, about 2.5% of children show a short stature due to several causes. Two clinical conditions are characterized by serum IGF-I low levels, idiopathic GH deficiency (IGHD), and GH insensitivity (GHI), and the phenotypic appearance of these patients may be very similar. We studied two children with short stature and similar phenotypes. The first case showed frontal bossing, doll face, acromicria, and truncal obesity, with a GH peak Laron syndrome was confirmed after the molecular analysis of the GH receptor (GHR) gene. IGHD type IA and Laron syndrome is characterized by opposite circulating levels of GH, while both have reduced levels of IGF-I, with an overlapping clinical phenotype, lacking the effects of IGF-I on cartilage. These classical cases show the importance of differential diagnosis in children with severe short stature. PMID:29850346

    Mice deficient in hepatocyte nuclear factor 1 alpha (HNF-1α) were produced by use of the Cre-loxP recombination system. HNF-1α-null mice are viable but sterile and exhibit a phenotype reminiscent of both Laron-type dwarfism and non-insulin-dependent diabetes mellitus (NIDDM). In contrast to an earlier HNF-1α-null mouse line that had been produced by use of standard gene disruption methodology (M. Pontoglio, J. Barra, M. Hadchouel, A. Doyen, C. Kress, J. P. Bach, C. Babinet, and M. Yaniv, Cell 84:575–585, 1996), these mice exhibited no increased mortality and only minimal renal dysfunction during the first 6 months of development. Both dwarfism and NIDDM are most likely due to the loss of expression of insulin-like growth factor I (IGF-I) and lower levels of insulin, resulting in stunted growth and elevated serum glucose levels, respectively. These results confirm the functional significance of the HNF-1α regulatory elements that had previously been shown to reside in the promoter regions of both the IGF-I and the insulin genes.

    Metabolic syndrome is a cluster of risk factors including obesity, dyslipidemia, hypertension, and insulin resistance. A number of theories have been speculated for the pathogenesis of metabolic syndrome including impaired glucose and lipid metabolism, lipotoxicity, oxidative stress, interrupted neurohormonal regulation and compromised intracellular Ca(2+) handling. Recent evidence has revealed that adults with severe growth hormone (GH) and insulin-like growth factor I (IGF-1) deficiency such as Laron syndrome display increased risk of stroke and cardiovascular diseases. IGF-1 signaling may regulate contractility, metabolism, hypertrophy, apoptosis, autophagy, stem cell regeneration and senescence in the heart to maintain cardiac homeostasis. An inverse relationship between plasma IGF-1 levels and prevalence of metabolic syndrome as well as associated cardiovascular complications has been identified, suggesting the clinical promises of IGF-1 analogues or IGF-1 receptor activation in the management of metabolic and cardiovascular diseases. However, the underlying pathophysiological mechanisms between IGF-1 and metabolic syndrome are still poorly understood. This mini-review will discuss the role of IGF-1 signaling cascade in the prevalence of metabolic syndrome in particular the susceptibility to overnutrition and sedentary life style-induced obesity, dyslipidemia, insulin resistance and other features of metabolic syndrome. Special attention will be dedicated in IGF-1-associated changes in cardiac responses in various metabolic syndrome components such as insulin resistance, obesity, hypertension and dyslipidemia. The potential risk of IGF-1 and IGF-1R stimulation such as tumorigenesis is discussed. Therapeutic promises of IGF-1 and IGF-1 analogues including mecasermin, mecasermin rinfabate and PEGylated IGF-1 will be discussed. Copyright © 2014 Elsevier Inc. All rights reserved.

    Patients with LS have an inborn growth hormone resistance, resulting in failure to generate IGF-1. The purpose of this study was to evaluate the size of the eye and orbit in LS. We retrospectively reviewed the MR imaging of the brain in 9 patients with LS for the following parameters: axial diameter of the globe, interzygomatic distance, perpendicular distance from the interzygomatic line to margins of the globe, medial-to-lateral diameter of the orbit at the anterior orbital rim, distance from the anterior orbital rim to the anterior globe, maximal distance between the medial walls of the orbits, lateral orbital wall angle, lateral orbital wall length, and mediolateral thickness of the intraorbital fat in the most cranial image of the orbit. All measurements were made bilaterally. Twenty patients referred for MR imaging for unrelated reasons served as control subjects. Compared with the control group, the patients with LS had a significantly smaller maximal globe diameter and shallower but wider orbits due to a shorter lateral wall, a smaller medial distance between the orbits, and a larger angle of the orbit. The ratio between the most anterior orbital diameter and the globe was greater than that in controls. The position of the globe was more anterior in relation to the interzygomatic line. Shallow and wide orbits and small globes relative to orbital size are seen in LS and may be secondary to IGF-1 deficiency.

    Full Text Available By definition, about 2.5% of children show a short stature due to several causes. Two clinical conditions are characterized by serum IGF-I low levels, idiopathic GH deficiency (IGHD, and GH insensitivity (GHI, and the phenotypic appearance of these patients may be very similar. We studied two children with short stature and similar phenotypes. The first case showed frontal bossing, doll face, acromicria, and truncal obesity, with a GH peak <0.05 ng/ml after stimuli and undetectable serum IGF-I levels. After PCR amplification of the whole GH1 gene, type IA idiopathic GHD was diagnosed. The second case had cranium hypoplasia, a large head, protruding forehead, saddle nose, underdeveloped mandible, and a micropenis. Basal GH levels were high (28.4 ng/ml while serum IGF-I levels were low and unchangeable during the IGF-I generation test. Laron syndrome was confirmed after the molecular analysis of the GH receptor (GHR gene. IGHD type IA and Laron syndrome is characterized by opposite circulating levels of GH, while both have reduced levels of IGF-I, with an overlapping clinical phenotype, lacking the effects of IGF-I on cartilage. These classical cases show the importance of differential diagnosis in children with severe short stature.

    Full Text Available The origin of hominins found on the remote Indonesian island of Flores remains highly contentious. These specimens may represent a new hominin species, Homo floresiensis, descended from a local population of Homo erectus or from an earlier (pre-H. erectus migration of a small-bodied and small-brained hominin out of Africa. Alternatively, some workers suggest that some or all of the specimens recovered from Liang Bua are pathological members of a small-bodied modern human population. Pathological conditions proposed to explain their documented anatomical features include microcephaly, myxoedematous endemic hypothyroidism ("cretinism" and Laron syndrome (primary growth hormone insensitivity. This study evaluates evolutionary and pathological hypotheses through comparative analysis of cranial morphology. Geometric morphometric analyses of landmark data show that the sole Flores cranium (LB1 is clearly distinct from healthy modern humans and from those exhibiting hypothyroidism and Laron syndrome. Modern human microcephalic specimens converge, to some extent, on crania of extinct species of Homo. However in the features that distinguish these two groups, LB1 consistently groups with fossil hominins and is most similar to H. erectus. Our study provides further support for recognizing the Flores hominins as a distinct species, H. floresiensis, whose affinities lie with archaic Homo.

    2005-02-01

    Present knowledge on the effects of growth hormone (GH) and insulin-like growth factor-I (IGF-I) deficiency on aging and lifespan are controversial. Studying untreated patients with either isolated GH deficiency due to GH gene deletion, patients with multiple pituitary hormone deficiency due to PROP-1 gene mutation and patients with isolated IGF-I deficiency due to deletions or mutations of the GH receptor gene (Laron syndrome); it was found, that these patients despite signs of early aging (wrinkled skin, obesity, insulin resistance and osteopenia) have a long life span reaching ages of 80-90 years. Animal models of genetic GH deficiencies such as Snell mice (Pit-1 gene mutations) the Ames mice (PROP-1 gene mutation) and the Laron mice (GH receptor gene knock-out) have a statistically significant higher longevity compared to normal controls. On the contrary, mice transgenic for GH and acromegalic patients secreting high amounts of GH have premature death. Those data raise the question whether pharmacological GH administration to adults is deleterious, in contrast to policies advocating such therapies.

    To date, about sixty different mutations within GH receptor (GHR) gene have been described in patients with GH insensitivity syndrome (GHI). In this report, we described a novel nonsense mutation of GHR. The patient was evaluated at the age of 6 yr, for short stature associated to clinical phenotype of GHI. GH, IGF-1, and GHBP levels were determined. The PCR products from exons 2-10 were sequenced. The patient had high GH (26 microg/L), low IGF-1 (22.5 ng/ml) and undetectable GHBP levels. The sequencing of GHR exon 5 disclosed adenine duplication at nucleotide 338 of GHR coding sequence (c.338dupA) in homozygous state. We described a novel mutation that causes a truncated GHR and a loss of receptor function due to the lack of amino acids comprising the transmembrane and intracellular regions of GHR protein, leading to GHI.

    Insulin-like growth factor I (IGF-I) is a peptide synthesized mainly in the liver by stimulation by pituitary growth hormone (GH). It circulates almost entirely bound to its binding proteins. It is the anabolic effector hormone of GH. It is the only treatment in states of GH resistance such as Laron syndrome and blocking antibodies to human GH. As it suppresses insulin and GH secretion it has been used in states of insulin resistance including Type II diabetes mellitus. IGF-I is administered by once or twice daily injections. Adverse effects are mostly caused by overdosage. The usual daily dose in children ranges from 100-200 microg/kg.

    Full Text Available Herein, we present a 14-year-old patient with short stature (134 cm referred from Paediatrics to our department for complementary evaluation since growth hormone (GH treatment failed to show any improvement. He was born premature and small for gestational age. Genital examination classified the patient as Tanner I–II with small penis and testicular size for his age. Biochemical analyses revealed normal GH levels with low serum insulin-like growth factor-1 (IGF-1. Molecular diagnosis confirmed several mutations in IGF1R and IGFALS, and so he was diagnosed with Laron Syndrome or GH insensibility and treated with IGF-1 substitutive therapy.

    The original centrally defining features of "Homo floresiensis" are based on bones represented only in the single specimen LB1. Initial published values of 380-mL endocranial volume and 1.06-m stature are markedly lower than later attempts to confirm them, and facial asymmetry originally unreported, then denied, has been established by our group and later confirmed independently. Of nearly 200 syndromes in which microcephaly is one sign, more than half include asymmetry as another sign and more than one-fourth also explicitly include short stature. The original diagnosis of the putative new species noted and dismissed just three developmental abnormalities. Subsequent independent attempts at diagnosis (Laron Syndrome, Majewski osteodysplastic primordial dwarfism type II, cretinism) have been hampered a priori by selectively restricted access to specimens, and disparaged a posteriori using data previously unpublished, without acknowledging that all of the independent diagnoses corroborate the patent abnormal singularity of LB1. In this report we establish in detail that even in the absence of a particular syndromic diagnosis, the originally defining features of LB1 do not establish either the uniqueness or normality necessary to meet the formal criteria for a type specimen of a new species. In a companion paper we present a new syndromic diagnosis for LB1.

This syndrome is due to mutation of GH receptor or IGF-1 gene and patients affected showed no response to GH therapy. The only treatment is recombinant IGF-1 (mecasermin, which has been available since 1986, but approved in the United States by the US Food and Drug Administration only in 2005 and in Europe by the European Medicines Agency in 2007. To date, few studies are available on long-term treatment with mecasermin in IGFD patients and some of them have a very small number of subjects. In this review we discuss briefly clinical features of severe primary IGFD, laboratory findings, and indications for treatment.

    2012-02-01

    We aim to review the clinical features of two renal tubular disorders characterized by sodium and potassium wasting: Bartter syndrome and Gitelman syndrome. Selected key references concerning these syndromes were analyzed, together with a PubMed search of the literature from 2000 to 2011. The clinical features common to both conditions and those which are distinct to each syndrome were presented. The new findings on the genetics of the five types of Bartter syndrome and the discrete mutations in Gitelman syndrome were reviewed, together with the diagnostic workup and treatment for each condition. Patients with Bartter syndrome types 1, 2 and 4 present at a younger age than classic Bartter syndrome type 3. They present with symptoms, often quite severe in the neonatal period. Patients with classic Bartter syndrome type 3 present later in life and may be sporadically asymptomatic or mildly symptomatic. The severe, steady-state hypokalemia in Bartter syndrome and Gitelman syndrome may abruptly become life-threatening under certain aggravating conditions. Clinicians need to be cognizant of such renal tubular disorders, and promptly treat at-risk patients.

    The paper describes the maxillo-facial and dental anomalies observed in some chromosome and non-chromosome poly-malformative syndromes ("Cri du chat" syndrome; Wilms' tumour; Sotos' syndrome; Goldenhar's syndrome). The Authors emphasise the possibility of diagnosing these multiple deformity syndromes from maxillo-facial alterations in early infancy; anomalous tooth position and structure cal also be successfully treated immediately after the first appearance of teeth. This is a particularly promising field of pediatrics and preventive pediatric medicine.

    The aim of this study was to investigate the developmental trajectories of verbal aggression, physical aggression, and temper tantrums in four genetic syndrome groups. Participants were part of the Australian Child to Adult Development Study (ACAD), which collected information from a cohort of individuals with an intellectual disability at five time points over 18 years. Data were examined from a total of 248 people with one of the four following syndromes: Down syndrome, Fragile X syndrome, Prader-Willi syndrome, or Williams syndrome. Changes in behaviors were measured using validated items from the Developmental Behavior Checklist (DBC). The results indicate that, while verbal aggression shows no evidence of diminishing with age, physical aggression, and temper tantrums decline with age before 19 years for people with Down syndrome, Fragile X syndrome, and William syndrome; and after 19 years for people with Prader-Willi syndrome. These findings offer a somewhat more optimistic outlook for people with an intellectual disability than has previously been suggested. Research is needed to investigate the mechanisms predisposing people with PWS to persistence of temper tantrums and physical aggression into adulthood. © 2015 Wiley Periodicals, Inc.

    2009-01-01

    We described three cases of superior mesenteric artery (SMA) syndrome, also known as Wilkie's syndrome, chronic duodenal ileus, or cast syndrome. This syndrome occurs when the third portion of the duodenum is compressed between the SMA and the aorta. The major risk factors for development of SMA syndrome are rapid weight loss and surgical correction of spinal deformities. The clinical presentation of SMA syndrome is variable and nonspecific, including nausea, vomiting, abdominal pain, and weight loss. The diagnosis is based on endoscopic, radiographic and tomographic findings of duodenal compression by the SMA. The treatment of SMA syndrome is aimed at the precipitating factor, which usually is related to weight loss. Therefore, conservative therapy with nutritional supplementation is the initial approach, and surgery is reserved for those who do not respond to nutritional therapy.

    Antiphospholipid syndrome is revealed by Budd Chiari syndrome in 5% of the cases. Antiphospholipid syndrome is characterized by venous or arterial thrombosis, foetal loss and positivity of antiphospholipid antibodies, namely lupus anticoagulant, anticardiolipin antibodies and anti-beta2-glycoprotein I. Anticardiolipin antibodies was reported in auto-immune thyroid disorders, particularly in Grave's disease. Antiphospholipid syndrome associated to Grave's disease was reported in only three cases. To describe a case report of association of Grave's disease and antiphospholipid syndrome. We report the first case of Grave's disease associated with antiphospholipid syndrome, revealed by Budd Chiari syndrome. Our observation is particular by the fact that it is about a patient presenting a Grave's disease associated with antiphospholipid syndrome revealed by Budd Chiari syndrome. This triple association has never been reported in literature. Although association between antiphospholipid syndrome and Grave's disease was previously described, further studies evaluating the coexistence of these two affections in the same patient would be useful.

      Wells syndrome has been described as an inflammatory disorder based on typical clinical appearance combined with the histopathological presence of eosinophilic infiltrates and flame figures in the absence of vasculitis. Churg-Strauss syndrome, on the other hand, is primarily a diffuse, necrotizing vasculitis but is also typically displaying eosinophils and flame figures. Despite several parallels, the present understanding of these two diseases excludes any pathogenetic relationship.   We describe the clinical course and histopathological appearance of three patients who had initially been diagnosed with Wells syndrome that developed into Churg-Strauss syndrome during the course of their disease.   The clinical presentation of all three patients led to the diagnosis of Wells syndrome by independent specialists. Histopathology showed an eosinophilic infiltrate and flame figures next to features of leukocytoclastic vasculitis. Detailed examination revealed asthma bronchiale and additional symptoms indicating Churg-Strauss syndrome. The initial diagnosis of Wells syndrome had to be revised to Churg-Strauss syndrome.   We conclude that Wells syndrome could be the starting point of a pathogenetic process that might reach its maximum in Churg-Strauss syndrome. As a clinical consequence, patients with Wells syndrome should be evaluated and followed for Churg-Strauss syndrome. © 2013 The International Society of Dermatology.

    The acronym LEOPARD stands for a syndromic association of Lentigines, Eletrocardiographic changes, Ocular hypertelorism, Pulmonic stenosis, Abnormal genitalia, Retardation of growth and sensorineural Deafness. Inheritance is autosomal dominant with high penetrance and variable expressivity. In 1990 Torok et al. reported on the association of LEOPARD and Marfan syndrome. In addition a clinical similarity (cardiac and cutaneous involvement) exists with the Watson syndrome (neurofibromatosis and pulmonic stenosis) which is linked to the marker D17S33 on chromosome 17. We studied possible linkage of LEOPARD syndrome to the Marfan syndrome locus on chromosome 15 (D15S1, MF13, and (TAAAA)n repeats) and to the NF-1 locus on chromosome 17 in a family with 9 cases of LEOPARD syndrome. Close linkage between LEOPARD syndrome and both the Marfan locus on chromosome 15 and the NF-1 locus on chromosome 17 was excluded (lod score <-2.0 through {theta} = 0.1).

    Metabolic syndrome is an increasing pathology in adults and in children, due to a parallel rise of obesity. Sedentary lifestyle, food habits, cultural influences and also a genetic predisposition can cause dyslipidemia, hypertension, abdominal obesity and insulin resistance which are the two main features of metabolic syndrome. Polycystic ovary syndrome (PCOS) is a condition directly associated with obesity, insulin resistance (HOMA index) and metabolic syndrome, and it is very interesting for its relationship and overlap with the metabolic syndrome. The relationship between the two syndromes is mutual: PCOS women have a higher prevalence of metabolic syndrome and also women with metabolic syndrome commonly present the reproductive/endocrine trait of PCOS. Prevention and treatment of metabolic syndrome and PCOS are similar for various aspects. It is necessary to treat excess adiposity and insulin resistance, with the overall goals of preventing cardiovascular disease and type 2 diabetes and improving reproductive failure in young women with PCOS. First of all, lifestyle changes, then pharmacological therapy, bariatric surgery and laparoscopic ovarian surgery represent the pillars for PCOS treatment.

    2006-06-15

    Coffin-Siris syndrome is a multiple congenital anomaly/mental retardation syndrome with phenotypic variability [OMIM 135900]. The diagnosis is based solely on clinical findings, as there is currently no molecular, biochemical, or cytogenetic analysis available to confirm a diagnosis. Although typically described as an autosomal recessive disorder, autosomal dominant inheritance has also been infrequently reported. We describe a mother and her two daughters who all have features that resemble Coffin-Siris syndrome. However, this is not a completely convincing diagnosis given that hypertelorism is not a feature of Coffin-Siris syndrome and the family is relatively mildly affected. Yet, this family provides further evidence of an autosomal dominant mode of inheritance for a likely variant of Coffin-Siris syndrome (at least in some families). In addition, Sibling 1 had premature thelarche. She is the second reported individual within the spectrum of Coffin-Siris syndrome to have premature thelarche, indicating that it may be a rare clinical feature. Copyright 2006 Wiley-Liss, Inc.

    Schinzel-Giedion syndrome is a rare recognizable malformation syndrome defined by characteristic facial features, profound developmental delay, severe growth failure, and multiple congenital anomalies. The causative gene of Schinzel-Giedion syndrome, SETBP1, has been identified, but limited cases have been confirmed by molecular analysis. We present a 9-month-old girl affected by West syndrome with Schinzel-Giedion syndrome. Congenital severe hydronephrosis, typical facial features, and multiple anomalies suggested a clinical diagnosis of Schinzel-Giedion syndrome. Hypsarrhythmia occurred at 7 months of age and was temporarily controlled by adrenocorticotropic hormone (ACTH) therapy during 5 weeks. SETBP1 mutational analysis showed the presence of a recurrent mutation, p.Ile871Thr. The implications in management of Schinzel-Giedion syndrome are discussed. © The Author(s) 2014.

    Primary or secondary IGF1 deficiency has been implicated in shortening of lifespan. This paper reviews available data on the influence of IGF1 deficiency on lifespan and longevity in animals and man. It has been shown that inactivation of the IGF1 gene or of the GH receptor in both invertebrates (C-elegans, flies-Drosphila) and rodents (mice and rats), leading to IGF1 deficiency, prolong life, particularly in females. In man, evaluation of the 2 largest cohorts of patients with Laron syndrome (inactive GH receptor resulting in IGF1 deficiency) in Israel and Ecuador revealed that despite their dwarfism and marked obesity, patients are alive at the ages of 75-78 years, with some having reached even more advanced ages. It is assumed that a major contributing factor is their protection from cancer, a major cause of death in the general population.

    Iliac vein compression syndrome (also known as May-Thurner syndrome or Cockett's syndrome) is a rare clinical entity in which the left common iliac vein is compressed when it passes between the right common iliac artery and the spine. The sustained compression and trauma caused by the pulsatile force of the artery on the vein damage the intima and lead to the formation of membranes or bands in the vascular lumen that hinder or obstruct the flow of blood in the vein, favoring thrombus formation. The current treatment strategy of choice is endovascular vein patch angioplasty and stenting with the aim of improving the caliber of the lumen and enabling normal venous drainage. We present two cases of May-Thurner syndrome and review the clinical and CT findings. Copyright © 2011 SERAM. Published by Elsevier Espana. All rights reserved.

    Dravet syndrome is an epileptic syndrome of infancy and early childhood. Most cases of Dravet syndrome seem to be due to a genetic defect causing the sodium channel to malfunction. We describe the main features of the syndrome. This epilepsy is medically intractable, but we call attention...... to the fact that some medications are of benefit and some could exacerbate the condition. Early recognition of the syndrome including by genetic testing could possibly improve outcome and reduce the need for other specialized investigations. Udgivelsesdato: 2010-Feb-22...

  8. A half-century of studies of growth hormone insensitivity/Laron syndrome: A historical perspective.

    Rosenbloom, Arlan L

    A growth hormone (GH) dependent substance responsible for sulfate uptake by costal cartilage of hypophysectomized rats, labeled sulfation factor, was reported in 1957. In 1962 the radioimmunoassay for GH was described. The clinical picture of severe GH deficiency but with high serum concentrations of GH was reported in 3 siblings in 1966 and followed by a 1968 report of 22 patients belonging to 14 consanguineous oriental Jewish families in Israel. Defective sulfation factor generation was demonstrated in 15 of these individuals and in a 1971 report; FFA response to IV GH and growth response to GH injections suggested competitive saturation of peripheral tissue receptors by an abnormal GH. However, studies published in 1973 demonstrated normal fractionation of their circulating GH, and normal binding of GH from 22 patients to various antisera used for radioimmunoassay. In 1976, the Israeli investigators reported that circulating GH from 7 patients reacted normally in the recently developed radioreceptor assay for GH. In 1984, using hepatic microsome pellets, they demonstrated that the defect was a failure of GH binding to receptors. Characterization of the human GH receptor (GHR) gene, reported in 1989, included the initial description of a genetic defect of the GHR in 2 of 9 Israeli patients. At about the same time began the identification in Ecuador of what was to become the largest population of GH insensitivity in the world, ~100 individuals, and the only substantial population with a common mutation of the GH receptor. Treatment studies with recombinant IGF-I began in 1990. Growth response was modest compared to that of GH treated GH deficient subjects. The spectrum of GH insensitivity has expanded beyond GH receptor deficiency to include postreceptor abnormalities: IGF-I gene mutation (1996); IGF-I receptor mutation (2003); signal transducer and activator of transcription 5b mutation (2003); and mutation of the GH-dependent acid labile subunit (2004). Rare conditions of GH insensitivity caused by GH receptor and postreceptor abnormalities have provided insights into the processes of growth, body composition, and metabolism.

    To observe clinical manifestations, behavioral characteristics, and effects of rehabilitation on a patient with pusher syndrome and unilateral spatial neglect caused by right thalamic hemorrhage. Assessment of pusher syndrome was made by the Scale for Contraversive pushing (SCP), and unilateral spatial neglect syndrome was diagnosed using line cancellation, letter and star cancellation, line bisection tests and copy and continuation of graphic sequence test. Behavioral therapy, occupational therapy, reading training and traditional Chinese medicine methods were adopted for treatment of pusher syndrome and unilateral spatial neglect. The patient showed typical pusher syndrome and unilateral spatial neglect symptoms. The pusher syndrome and unilateral spatial neglect symptoms were significantly improved following rehabilitation treatments. Pusher syndrome and unilateral spatial neglect syndrome occurred simultaneously after right thalamic hemorrhage. Early rehabilitation therapy can reduce the symptoms of pusher syndrome and unilateral spatial neglect syndrome and improve motor function.

    Polycystic ovary syndrome (PCOS) is a heterogeneous disorder, where the main clinical features include menstrual irregularities, sub-fertility, hyperandrogenism, and hirsutism. The prevalence of PCOS depends on ethnicity, environmental and genetic factors, as well as the criteria used to define it. On the other hand, metabolic syndrome is a constellation of metabolic disorders which include mainly abdominal obesity, insulin resistance, impaired glucose metabolism, hypertension and dyslipidaemia. These associated disorders directly increase the risk of Type 2 diabetes mellitus (DMT2), coronary heart disease (CHD), cardiovascular diseases (CVD) and endometrial cancer. Many patients with PCOS have features of metabolic syndrome such as visceral obesity, hyperinsulinaemia and insulin resistance. These place patients with PCOS under high risk of developing cardiovascular disease (CVD), Type 2 diabetes (DMT2) and gynecological cancer, in particular, endometrial cancer. Metabolic syndrome is also increased in infertile women with PCOS. The aim of this review is to provide clear and up to date information about PCOS and its relationship with metabolic syndrome, and the possible interaction between different metabolic disorders.

    Objective: To determine the frequency of metabolic syndrome in male patients presenting with acute coronary syndrome Study design: A Descriptive study Place and duration of study: Armed Forces Institute of Cardiology and National Institute of Heart Diseases, Rawalpindi, from October 2007 to September 2008 Patients and Methods: Male patients with acute coronary syndrome (ACS) were included. Patients having angioplasty (PCI), coronary artery bypass surgery in the past and other co-morbid diseases were excluded. All patients were assessed for the presence of five components of metabolic syndrome including hypertension, HDL-Cholesterol and triglycerides, glucose intolerance and abdominal obesity. Systolic, diastolic blood pressures, waist circumference (WC) and body mass index (BMI) were measured. ECG, cardiac enzymes, fasting glucose and lipid profile were also done. Results: A total of 135 male patients of ACS were studied with a mean age of 54.26 +- 11 years. Metabolic syndrome (MS) was present in 55 (40.7%) patients. MS with all five components was documented in 4 (7.27%) while MS with four and three components was seen in 23 (41.81%) and 28 (50.90%) patients respectively. Only 24 (43.63%) patients with MS had diabetes mellitus, remaining 31(56.36%) were non diabetic. Frequencies of diabetes, hypertension and family history of CAD were significantly higher (p<0.05) in patients with metabolic syndrome as compared to patients with normal metabolic status. Conclusion: Metabolic syndrome is fairly common and important risk factor in patients of IHD. Other risk factors like smoking, dyslipidemia, hypertension and diabetes were also frequently found. Public awareness to control the risk factors can reduce the prevalence of CAD in our country. (author)

    Metabolic syndrome is comprised of a combination of the following states: increased insulin resistance, dyslipidemia, cardiovascular disease, and increased abdominal obesity. Women with polycystic ovary syndrome (PCOS) have an increased risk of developing metabolic syndrome over the course of their lives. Metabolic syndrome increases risk of major cardiovascular events, morbidity, quality of life, and overall health care costs. Though metabolic syndrome in women with PCOS is an area of great concern, there is no effective individual medical therapeutic to adequately treat this issue. This article will review key aspects of metabolic syndrome in PCOS. We will discuss classic and novel therapeutics to address metabolic syndrome in women with PCOS. We will conclude with the importance of developing strategic interventions to increase the compliance to lifestyle and dietary modification, in addition to appreciation of the emerging pharmaceutical therapeutics available. Innovation in lifestyle modification, including diet, exercise, with and without dedicated stress reduction techniques is the future in treatment of metabolic syndrome in PCOS. Application of novel interventions, such as group medical care, may improve future adherence to lifestyle modification recommendations, in addition to or in combination with pharmaceutical therapeutics.

    2017-01-01

    Most cases of Van der Woude syndrome are caused by a mutation to interferon regulatory factor 6 on chromosome 1. Turner syndrome is caused by complete or partial absence of the second sex chromosome in girls. We describe a unique case of the two syndromes occurring concurrently though apparently independently in a girl with Van der Woude syndrome diagnosed at birth and Turner syndrome at 14 years 9 months. Short stature was initially misattributed to Van der Woude syndrome and pituitary insufficiency associated with clefts before correctly diagnosing Turner syndrome. We discuss the prevalence of delayed diagnosis of Turner syndrome, the rarity of reports of concurrent autosomal chromosome mutation and sex chromosome deletion, as well as the need to consider the diagnosis of Turner syndrome in all girls with short stature regardless of prior medical history.

    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.

    TAFRO syndrome is a newly recognized variant of idiopathic multicentric Castleman disease (iMCD) that involves a constellation of syndromes: thrombocytopenia (T), anasarca (A), fever (F), reticulin fibrosis (R), and organomegaly (O). Thrombocytopenia and severe anasarca accompanied by relatively low serum immunoglobulin levels are characteristic clinical findings of TAFRO syndrome that are not present in iMCD-not otherwise specified (iMCD-NOS). Lymph node biopsy is recommended to exclude other diseases and to diagnose TAFRO syndrome, which reveals characteristic histopathological findings similar to hyaline vascular-type CD. TAFRO syndrome follows a more aggressive course, compared with iMCD-NOS, and there is no standard treatment. Copyright © 2017 Elsevier Inc. All rights reserved.

    Individuals with Usher syndrome or CHARGE syndrome are faced with a number of difficulties concerning hearing, vision, balance, and language development. The aim of the study is to describe the developmental characteristics of children with Usher syndrome and CHARGE syndrome, respectively. Data about the developmental characteristics of 26 children with Usher syndrome and 17 children with CHARGE syndrome was obtained. Associations between deafblindness (dual sensory loss), motor development (age of walking), language abilities, and intellectual outcome of these children were explored for each group independently. Both groups of children face a number of difficulties associated with vision, hearing, language, balance and intellectual outcome. Intellectual disability and/or language delay was found among 42% of the children with Usher syndrome and among 82% of the children with CHARGE syndrome. Intellectual disability was associated with language delay and age of walking for both groups. Even though Usher and CHARGE are two different genetic syndromes, both groups are challenged with a number of similar developmental delays. Clinicians need to be aware of several developmental issues in order to offer adequate support to children with Usher or CHARGE syndrome. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

    2017-01-01

    An increased risk of preterm birth in women with joint hypermobility syndrome or Ehlers-Danlos syndrome is suspected. In this nationwide cohort study from 1997 through 2011, women with either joint hypermobility syndrome or Ehlers-Danlos syndrome or both disorders were identified through the Swedish Patient Register, and linked to the Medical Birth Register. Thereby, 314 singleton births to women with joint hypermobility syndrome/Ehlers-Danlos syndrome before delivery were identified. These births were compared with 1 247 864 singleton births to women without a diagnosis of joint hypermobility syndrome/Ehlers-Danlos syndrome. We used logistic regression, adjusted for maternal age, smoking, parity, and year of birth, to calculate adjusted odds ratios for adverse pregnancy outcomes. Maternal joint hypermobility syndrome/Ehlers-Danlos syndrome was not associated with any of our outcomes: preterm birth (adjusted odds ratio = 0.6, 95% confidence interval 0.3-1.2), preterm premature rupture of membranes (adjusted odds ratio = 0.8; 95% confidence interval 0.3-2.2), cesarean section (adjusted odds ratio = 0.9, 95% confidence interval 0.7-1.2), stillbirth (adjusted odds ratio = 1.1, 95% confidence interval 0.2-7.9), low Apgar score (adjusted odds ratio = 1.6, 95% confidence interval 0.7-3.6), small for gestational age (adjusted odds ratio = 0.9, 95% confidence interval 0.4-1.8) or large for gestational age (adjusted odds ratio = 1.2, 95% confidence interval 0.6-2.1). Examining only women with Ehlers-Danlos syndrome (n = 62), we found a higher risk of induction of labor (adjusted odds ratio = 2.6; 95% confidence interval 1.4-4.6) and amniotomy (adjusted odds ratio = 3.8; 95% confidence interval 2.0-7.1). No excess risks for adverse pregnancy outcome were seen in joint hypermobility syndrome. Women with joint hypermobility syndrome/Ehlers-Danlos syndrome do not seem to be at increased risk of adverse pregnancy outcome. © 2016 Nordic Federation of

    Wolf-Hirschhorn syndrome (WHS) is a chromosome disorder (4p-syndrome) which is characterized by craniofacial features and epileptic seizures. Here, we report a case of WHS with West syndrome, in whom the seizures were refractory to several antiepileptic drugs but were responsive to the addition of lamotrigine. The patient had epileptic spasms at age seven months. The interictal electroencephalogram was hypsarrhythmic. After adding lamotrigine, seizures decreased remarkably, and spasms disappeared. We have identified and described the very rare case of a girl with WHS who also developed West syndrome. In this case, adding lamotrigine to her medications effectively treated the spasms.

    Poland's syndrome consists of the variable clinical features, but always includes unilateral aplasia of the chest wall muscles and ipsilateral anomalies of upper extremity. The incidence of Poland's syndrome, reported by different authors ranges from 1:10,000 to 1:100,000 and is observed more frequently in males than in females with the right side of the body affected more often than the left. The etiology of this syndrome is still discussed. However most of described cases were sporadic, rare familial incidence of Poland's syndrome were also presented. Therefore different etiologic factors of the Poland's syndrome are taken into account: genetic, vascular compromise during early stages of embriogenesis but also teratogenic effect of environmental xenobiotics (e.g. cigarette smoking by pregnant women). The authors present also the case of 20-years old man with inherited bilateral syndactyly with the right side aplasia of major pectoralis muscle and face asymmetry. The familial history was negative in respect to the features, associated with Poland's syndrome.

    The authors present characteristics of Parental Alienation Syndrome (PAS) proposed by Gardner as well as data, which may help to differentiate that syndrome with real psychological, physical and sexual abuse. The consequences of Gardner Syndrome for legal decisions in the court cases of child custody and the critique of this syndrome in forensic and psychiatric literature are also discussed, and several questions posed. Authors propose to treat Gardner Syndrome not as as a child disorder but as a specific, dynamic family situation, which occurs sometimes, during divorce and fight about child custody.

    Burning mouth syndrome is distressing to both the patient and practitioner unable to determine the cause of the patient's symptoms. Burning mouth syndrome is a diagnosis of exclusion, which is used only after nutritional deficiencies, mucosal disease, fungal infections, hormonal disturbances and contact stomatitis have been ruled out. This article will explore the many causes and treatment of patients who present with a chief complaint of "my mouth burns," including symptomatic treatment for those with burning mouth syndrome.

  2. Effects of growth hormone and insulin-like growth factor 1 deficiency on ageing and longevity.

    Laron, Zvi

    2002-01-01

    Present knowledge on the effects of growth hormone (GH)/insulin-like growth hormone (IGF)1 deficiency on ageing and lifespan are reviewed. Evidence is presented that isolated GH deficiency (IGHD), multiple pituitary hormone deficiencies (MPHD) including GH, as well as primary IGE1 deficiency (GH resistance, Laron syndrome) present signs of early ageing such as thin and wrinkled skin, obesity, hyperglycemia and osteoporosis. These changes do not seem to affect the lifespan, as patients reach old age. Animal models of genetic MPHD (Ames and Snell mice) and GH receptor knockout mice (primary IGF1 deficiency) also have a statistically significant higher longevity compared to normal controls. On the contrary, mice transgenic for GH and acromegalic patients secreting large amounts of GH have premature death. In conclusion longstanding GH/IGF1 deficiency affects several parameters of the ageing process without impairing lifespan, and as shown in animal models prolongs longevity. In contrast high GH/IGF1 levels accelerate death.

    This study evaluates the impact in the stability and management of the marriage of parents of a child with Down or Rett Syndrome. Morbidity of the syndromes and the marital status of the couples before and after the birth of the affected children were considered variables. The divorce rate in families with Down syndrome was 10%, similar to the Brazilian rate population. In Rett Syndrome, the divorce rate was significantly higher, 23.5%. The higher morbidity of Rett Syndrome, and the moment of diagnosis could be relevant factors for the increased divorce rate related to this syndrome.

  6. The sick-building syndrome; Das Sick-Building-Syndrom

    Energy Technology Data Exchange (ETDEWEB)

    Henne, A.; Neumann, H.F.; Winneke, G.

    1992-12-31

    The sick-building syndrome is characterized by the presence of general, non-specific symptoms (e.g., headache, tiredness, respiratory problems, eye trouble, vertigo, nausea, unspecific hypersensitivity) in association with a particular indoor ambience. It is clearly distinguishable from `building-related illness`, referring to a well-defined clinical syndrome due to staying in a building and for which a cause can, in general, be established. Disorders in the case of the sick-building syndrome are manifold and confirmed objectifiable results are hardly available so far. Yet there are some organ-related methods for the confirmation of findings concerning, for instance, the eyes, the skin and the area of the nose. The causes of the incidence of sick-building syndrome are more or less unclear. It is a multifactorial phenomenon involving physical, biological, chemical, individual-specific and psychological factors. Buildings where sick-building syndrome occurs typically exhibit certain properties. The European Community has already made proposals for the investigation of incriminated buildings. A systematic survey by questionnaire together with individual interviews plays an import part towards clarifying the syndrome. (orig./UWA) [Deutsch] Das Sick-Building-Syndrom beschreibt das Vorhandensein von allgemeinen, nicht spezifischen Symptomen (z.B. Kopfschmerzen, Muedigkeit, Atembeschwerden, Augenreizungen, Schwindelgefuehl, Uebelkeit, unspezifische Ueberempfindlichkeit), assoziiert mit einer besonderen Innenraumumgebung. Deutlich hiervon abzugrenzen ist die ``Building related illness``, bei der ein klinisch definiertes Krankheitsbild vorliegt, das durch den Aufenthalt im Gebaeude verursacht wird und fuer das im allgemeinen eine Ursache ermittelt werden kann. Das Beschwerdebild beim Sick-Building-Syndrom ist vielfaeltig, und gesicherte, objektivierbare Befunde liegen hierzu bisher kaum vor.

  8. Syndromes with supernumerary teeth.

    Lubinsky, Mark; Kantaputra, Piranit Nik

    2016-10-01

    While most supernumerary teeth are idiopathic, they can be associated with a number of Mendelian syndromes. However, this can also be a coincidental finding, since supernumerary teeth occur in 6% or more of the normal population. To better define this relationship, we analyzed the evidence for specific associations. We excluded conditions with a single affected patient reported, supernumerary teeth adjacent to clefts or other forms of alveolar disruption (as secondary rather than primary findings), and natal teeth, which can involve premature eruption of a normal tooth. Since, the cause of supernumerary teeth shows considerable heterogeneity, certain findings are less likely to be coincidental, such as five or more supernumerary teeth in a single patient, or locations outside of the premaxilla. We found only eight genetic syndromes with strong evidence for an association: cleidocranial dysplasia; familial adenomatous polyposis; trichorhinophalangeal syndrome, type I; Rubinstein-Taybi syndrome; Nance-Horan syndrome; Opitz BBB/G syndrome; oculofaciocardiodental syndrome; and autosomal dominant Robinow syndrome. There is also suggestive evidence of an association with two uncommon disorders, Kreiborg-Pakistani syndrome (craniosynostosis and dental anomalies), and insulin-resistant diabetes mellitus with acanthosisnigricans. An association of a Mendelian disorder with a low frequency manifestation of supernumerary teeth is difficult to exclude without large numbers, but several commonly cited syndromes lacked evidence for clear association, including Hallermann-Streiff syndrome, Fabry disease, Ehlers-Danlos syndrome, Apert and Crouzon syndromes, Zimmermann-Laband syndrome, and Ellis-van Creveld syndrome. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    Autoimmune/inflammatory syndrome induced by adjuvants (ASIA) has been widely described in many studies conducted thus far. The syndrome incorporates five immune-mediated conditions, all associated with previous exposure to various agents such as vaccines, silicone implants and several others. The emergence of ASIA syndrome is associated with individual genetic predisposition, for instance those carrying HLA-DRB1*01 or HLA-DRB4 and results from exposure to external or endogenous factors triggering autoimmunity. Such factors have been demonstrated as able to induce autoimmunity in both animal models and humans via a variety of proposed mechanisms. In recent years, physicians have become more aware of the existence of ASIA syndrome and the relationship between adjuvants exposure and autoimmunity and more cases are being reported. Accordingly, we have created a registry that includes at present more than 300 ASIA syndrome cases that have been reported by different physicians worldwide, describing various autoimmune conditions induced by diverse adjuvants. In this review, we have summarized the updated literature on ASIA syndrome and the knowledge accumulated since 2013 in order to elucidate the association between the exposure to various adjuvant agents and its possible clinical manifestations. Furthermore, we especially referred to the relationship between ASIA syndrome and systemic lupus erythematosus (SLE) and antiphospholipid syndrome (APS).

    Ratzinger, Gudrun; Zankl, Julia; Eisendle, Klaus; Zelger, Bernhard

    2014-01-01

    Wells' syndrome is defined as an inflammatory disorder with the histopathological presence of eosinophilic infiltrates and flame figures in the absence of vasculitis. Eosinophilic leukocytoclastic vasculitis shows eosinophilic infiltrates in combination with vasculitic changes. And Churg Strauss Syndrome comprises all three characteristics - eosinophilic infiltrates, vasculitis and flame figures. To determine whether these three diseases are distinct entities or different manifestations of a similar clinicopathologic process. Histopathological samples and clinical courses of 17 patients with eosinophilic infiltrates, flame figures and clinical features of Wells' syndrome were re-evaluated. Histopathologically, we focused on the presence or absence of vasculitic features. Clinically, we included only patients who were diagnosed with Wells' syndrome at least once in the course of their disease. 4 patients were finally diagnosed with Wells' syndrome, 5 with eosinophilic leukocytoclastic vasculitis and 6 with Churg Strauss syndrome. Further, we had one case of an overlap between Wells' syndrome and eosinophilic vasculitis and one case of Wegener granulomatosis. Vasculitic features were found in the samples of all patients. Histologically, we find vasculitic features in typical presentations of Wells' syndrome. Clinically, we find typical features of Wells' syndrome in patients finally diagnosed with eosinophilic leukocytoclastic vasculitis or Churg Strauss syndrome. Furthermore, we have observed and formerly reported 3 patients with progression from Wells' syndrome to Churg Strauss syndrome. Thus, we assume that eosinophilic leukocytoclastic vasculitis might form a bridge between Wells' syndrome and Churg Strauss syndrome.

    A few isolated reports have described an association between Noonan syndrome and cerebrovascular abnormalities, including moyamoya syndrome. These reports have been limited to pediatric patients presenting with recurrent transient ischemic attacks (TIA) or headaches. Management has primarily been pharmacologic, with only one prior report of surgical revascularization to our knowledge. We report four cases of Noonan syndrome patients presenting with headaches and/or sensorimotor strokes in childhood that caused unilateral sensorimotor impairment. Cerebral angiography and MRI revealed bilateral moyamoya syndrome. All patients underwent successful bilateral extracranial-to-intracranial revascularization. The first patient was a 10-year-old girl who presented following a hemorrhagic stroke and recovered well after indirect bypass. The second patient was an adult with a history of childhood stroke whose symptoms progressed in adulthood. She underwent a direct bypass and improved, but continued to experience TIA at her 4 year follow-up. The third patient was a 7-year-old girl with headaches and a new onset TIA who failed pharmacological therapy and subsequently underwent bilateral indirect bypass. The fourth patient was a 24-year-old woman with worsening headaches and an occluded left middle cerebral artery from unilateral moyamoya syndrome. A left sided direct bypass was completed given delayed MRI perfusion with poor augmentation. To our knowledge these are the first reported surgical cases of combined Noonan and moyamoya syndrome. These cases highlight the need to recognize moyamoya syndrome in patients with Noonan syndrome. Early surgical revascularization should be pursued in order to prevent symptom progression.

    2003-01-01

    Bardet-Biedl syndrome (BBS) and Usher syndrome (USH) are the most prevalent syndromic forms of retinitis pigmentosa (RP), together they make up almost a quarter of the patients with RP. BBS is defined by the association of retinopathy, obesity, hypogonadism, renal dysfunction, postaxial polydactyly and mental retardation. This clinically complex syndrome is genetically heterogeneous with linkage to more than 6 loci, and 4 genes have been cloned so far. Recent molecular data present evidence that, in some instances, the clinical manifestation of BBS requires recessive mutations in 1 of the 6 BBS loci plus one or two additional mutations in a second BBS locus (tri- or tetra-allelic inheritance). USH is characterized by the combination of congenital or early-onset sensorineural deafness, RP, and variable degrees of vestibular dysfunction. Each of the three clinical types is genetically heterogeneous: 7 loci have been mapped for type 1, three loci for type 2, and two loci for type 3. Currently, 6 USH genes (MYO7A, USH1C, CDH23, PCDH15, USH2A, USH3) have been identified. Pathogenetically, mutations of the USH1 genes seem to result in defects of auditory and retinal sensory cells, the USH 2 phenotype is caused by defects of extracellular matrix or cell surface receptor proteins, and USH3 may be due to synaptic disturbances. The considerable contribution of syndromic forms of RP requires interdisciplinary approaches to the clinical and diagnostic management of RP patients.

    Patients with Munchausen syndrome purposefully injure themselves, often with the injection of foreign materials, to gain hospital admission and the attention associated with having a difficult-to-identify condition. Munchausen syndrome by proxy occurs when a child's caregiver, typically the mother, injures the child for the same reasons. Cases of Munchausen syndrome and Munchausen syndrome by proxy with primary cutaneous involvement appear to be rarely described in the literature suggesting either that diagnosis is not made readily or that it is, in fact, an uncommon disorder. At the center of both conditions is significant psychological pathology and treatment is difficult as many patients with Munchausen syndrome when confronted with these diagnostic possibilities simply leave the hospital. Little is known about the long-term outcome or prognosis of these patients. Copyright © 2014 American Academy of Dermatology, Inc. Published by Mosby, Inc. All rights reserved.

  7. Redefining syndromic surveillance

    Directory of Open Access Journals (Sweden)

    Rebecca Katz

    2011-12-01

    Full Text Available With growing concerns about international spread of disease and expanding use of early disease detection surveillance methods, the field of syndromic surveillance has received increased attention over the last decade. The purpose of this article is to clarify the various meanings that have been assigned to the term syndromic surveillance and to propose a refined categorization of the characteristics of these systems. Existing literature and conference proceedings were examined on syndromic surveillance from 1998 to 2010, focusing on low- and middle-income settings. Based on the 36 unique definitions of syndromic surveillance found in the literature, five commonly accepted principles of syndromic surveillance systems were identified, as well as two fundamental categories: specific and non-specific disease detection. Ultimately, the proposed categorization of syndromic surveillance distinguishes between systems that focus on detecting defined syndromes or outcomes of interest and those that aim to uncover non-specific trends that suggest an outbreak may be occurring. By providing an accurate and comprehensive picture of this field’s capabilities, and differentiating among system types, a unified understanding of the syndromic surveillance field can be developed, encouraging the adoption, investment in, and implementation of these systems in settings that need bolstered surveillance capacity, particularly low- and middle-income countries.

    Synonyms for the `battered child` syndrome (BCS) are terms describing the physical and body aspects of the process, such as `child abuse`, or `non-accidental injury`. These are to be distinguished from the psychic aspects and abuse, emotional and bodily neglect, and sexual abuse. Most cases are one or another combination of these aspects. Radiology is the essential method for giving proof of such abuses, identifying the signs of maltreatment in a medical record, or for disproving suspected abuse. (orig./AJ) [Deutsch] Als Synonym fuer das `Battered-Child`-Syndrom (BCS) stehen die Begriffe der koerperlichen-/physikalischen-Kindesmisshandlung, im angelsaechsischen Sprachraum die Begriffe `Child Abuse` und `Nonaccidental Injury`. Vom Syndrom abzugrenzen sind die seelische Misshandlung, die seelische und koerperliche Vernachlaessigung, und der sexuelle Missbrauch. Kombinationsformen sind nicht selten. Bei der Diagnostik des Syndroms spielt die Radiologie eine entscheidende Rolle. So hilft der Einsatz adaequater Untersuchungsmethoden, den Tatbestand der Misshandlung zu identifizieren und zu dokumentieren, aber auch einen Verdacht zu widerlegen. (orig./AJ)

    Burnout Syndrome is the extreme emotional response to chronic occupational stress, manifesting as physical and mental exhaustion. Although associated with higher prevalence of cardiovascular risk factors, no study so far has evaluated whether the Burnout Syndrome could be a prevalent factor in non-elderly individuals active in the labor market, admitted for acute coronary syndrome (ACS). To evaluate the prevalence of the Burnout Syndrome in non-elderly, economically active patients, hospitalized with ACS. Cross-sectional study conducted in a tertiary and private cardiology center, with economically active patients aged Burnout Syndrome was evaluated with the Burnout Syndrome Inventory (BSI), which assesses workplace conditions and four dimensions that characterize the syndrome: emotional exhaustion (EE), emotional distancing (EmD), dehumanization (De) and professional fulfillment (PF). The Lipp's Stress Symptoms Inventory for Adults (LSSI) was applied to evaluate global stress. Of 830 patients evaluated with suspected ACS, 170 met the study criteria, 90% of which were men, overall average age was 52 years, and 40.5% had an average income above 11 minimum wages. The prevalence of the Burnout Syndrome was 4.1%. When we evaluated each dimension individually, we found high EE in 34.7%, high De in 52.4%, high EDi in 30.6%, and low PF in 5.9%. The overall prevalence of stress was 87.5%. We found a low prevalence of Burnout Syndrome in an economically active, non-elderly population among patients admitted for ACS in a tertiary and private hospital.

Exact data about epidemiology of the syndrome are not available; the syndrome is extremely rare. Most of the patients are white middle-aged women, in the fourth to seventh decade of life but the syndrome has also been described in children and adolescents. The dysphagia is usually painless and intermittent or progressive over years, limited to solids and sometimes associated with weight loss. Symptoms resulting from anemia (weakness, pallor, fatigue, tachycardia may dominate the clinical picture. Additional features are glossitis, angular cheilitis and koilonychia. Enlargement of the spleen and thyroid may also be observed. One of the most important clinical aspects of Plummer-Vinson syndrome is the association with upper alimentary tract cancers. Etiopathogenesis of Plummer-Vinson syndrome is unknown. The most important possible etiological factor is iron deficiency. Other possible factors include malnutrition, genetic predisposition or autoimmune processes. Plummer-Vinson syndrome can be treated effectively with iron supplementation and mechanical dilation. In case of significant obstruction of the esophageal lumen by esophageal web and persistent dysphagia despite iron supplementation, rupture and dilation of the web are necessary. Since Plummer-Vinson syndrome is associated with an increased risk of squamous cell carcinoma of the pharynx and the esophagus, the patients should be followed closely.

    2012-08-01

    Wolfram syndrome 1 (WS1) is an autosomal recessive disorder characterized by diabetes insipidus, diabetes mellitus, optic atrophy, and deafness (DI DM OA D syndrome) associated with other variable clinical manifestations. The causative gene for WS1 (WFS1) encoding wolframin maps to chromosome 4p16.1. Wolframin has an important function in maintaining the homeostasis of the endoplasmic reticulum (ER) in pancreatic β cells. Recently, another causative gene, CISD2, has been identified in patients with a type of Wolfram syndrome (WS2) resulting in early optic atrophy, diabetes mellitus, deafness, decreased lifespan, but not diabetes insipidus. The CISD2-encoded protein ERIS (endoplasmic reticulum intermembrane small protein) also localizes to ER, but does not interact directly with wolframin. ERIS maps to chromosome 4q22. Numerous studies have shown an interesting similarity between WFS1 and CISD2 genes. Experimental studies demonstrated that the Cisd2 knockout (Cisd2) mouse shows premature aging and typical symptoms of Wolfram syndrome. These researches provide interesting insight into the relation of neurodegenerative diseases, mitochondrial disorders, and autophagy and are useful for the pathophysiological understanding of both Wolfram syndrome and mitochondrial-mediated premature aging. The knowledge of WS1 and WS2 pathogenesis, and of the interactions between WFS1 and CISD2 genes, is useful for accurate diagnostic classification and for diagnosis of presymptomatic individuals.

    2011-09-01

    Full Text Available Background: Treacher-Collins syndrome is a congenital craniofacial disorder with multiple anomalies. This syndrome affects the maxilla, mandible, eyes, middle and outer ears, and soft palate. Conductive hearing loss due to the deformities of the middle and external ears is prevalent. The characteristics of this syndrome include multiple and serious threats to normal communication development in children. In this study, speech and language features of a Persian speaking child with this syndrome are presented.Case: The case was an 8-year old girl with Treacher-Collins syndrome and bilateral moderate conductive hearing loss due to atretic canal. In language and speech assessments, moderate hypernasality, numerous compensatory errors and morphosyntactic deficits were observed. There were 13 phonemes that were incorrectly produced at least in one position. Besides, she used 22 types of phonological processes that were abnormal and disappear before the age of three in normal Persian speaking children.Conclusion: Moderate hearing loss, velopharyngeal incompetency, malocclusion and dental anomalies, attention deficit/hyperactivity disorder (ADHD and environmental factors resulted in severe speech and language disorders in this case. These disorders affected her academic performance as well. Moderate hypernasality, numerous compensatory errors, and excessive and abnormal use of phonological processes were not presented as prevalent characteristics of Treacher-Collins syndrome in other resources.

    2013-01-01

    Some headache syndromes have few cases reported in the literature. Their clinical characteristics, pathogenesis, and treatment may have not been completely defined. They may not actually be uncommon but rather under-recognized and/or underreported. A literature review of unusual headache syndromes, searching PubMed and ISI Web of Knowledge, was performed. After deciding which disorders to study, relevant publications in scientific journals, including original articles, reviews, meeting abstracts, and letters or correspondences to the editors were searched. This paper reviewed the clinical characteristics, the pathogenesis, the diagnosis, and the treatment of five interesting and unusual headache syndromes: exploding head syndrome, red ear syndrome, neck-tongue syndrome, nummular headache, and cardiac cephalgia. Recognizing some unusual headaches, either primary or secondary, may be a challenge for many non-headache specialist physicians. It is important to study them because the correct diagnosis may result in specific treatments that may improve the quality of life of these patients, and this can even be life saving. © 2013 American Headache Society.

    Full Text Available Background: Burnout Syndrome is the extreme emotional response to chronic occupational stress, manifesting as physical and mental exhaustion. Although associated with higher prevalence of cardiovascular risk factors, no study so far has evaluated whether the Burnout Syndrome could be a prevalent factor in non-elderly individuals active in the labor market, admitted for acute coronary syndrome (ACS. Objective: To evaluate the prevalence of the Burnout Syndrome in non-elderly, economically active patients, hospitalized with ACS. Methods: Cross-sectional study conducted in a tertiary and private cardiology center, with economically active patients aged <65 years, hospitalized with diagnosis of ACS. The Burnout Syndrome was evaluated with the Burnout Syndrome Inventory (BSI, which assesses workplace conditions and four dimensions that characterize the syndrome: emotional exhaustion (EE, emotional distancing (EmD, dehumanization (De and professional fulfillment (PF. The Lipp’s Stress Symptoms Inventory for Adults (LSSI was applied to evaluate global stress. Results: Of 830 patients evaluated with suspected ACS, 170 met the study criteria, 90% of which were men, overall average age was 52 years, and 40.5% had an average income above 11 minimum wages. The prevalence of the Burnout Syndrome was 4.1%. When we evaluated each dimension individually, we found high EE in 34.7%, high De in 52.4%, high EDi in 30.6%, and low PF in 5.9%. The overall prevalence of stress was 87.5%. Conclusion: We found a low prevalence of Burnout Syndrome in an economically active, non-elderly population among patients admitted for ACS in a tertiary and private hospital.

    2017-01-01

    The purpose of this study is to examine whether water and air pollutants have a relationship with an increase in the genetic disorders Turner syndrome and Down syndrome, which are caused by congenital chromosomal abnormalities, and to generate a hypothesis about the genetic health effects of environmental pollutants. A panel regression based on random effect was conducted on Korea's metropolitan councils from 2012 to 2014. The dependent variable was the number of Turner syndrome and Down syndrome cases, and the main independent variables were those regarding the water and air pollution. Air pollutants did not have a significant impact on the number of Turner syndrome and Down syndrome cases; however, the increase in number of wastewater discharge companies did have a significant relationship with the number of cases. The more the number of wastewater discharge companies, the more the number Turner syndrome and Down syndrome cases were observed. Therefore, scientific investigation on water and air pollutants in relation with genetic health effects needs to be performed.

    Full Text Available Abstract Introduction We report the case of an unusual association of Coffin-Siris syndrome with Mayer-Rokitansky-Küster-Hauser syndrome. This association has never previously been reported in the medical literature. Case presentation A nine-year-old Indian girl was referred to our hospital for growth retardation, mental retardation, lax joints, generalized hypertrichosis, and hypoplastic fifth fingernails and toenails. A thorough medical examination and evaluation revealed she had phenotypic features of Coffin-Siris syndrome, with Mayer-Rokitansky-Küster-Hauser syndrome on radiological evaluation. The karyotype of our patient was normal. Conclusion In an unexplained case of mental retardation with facies suggestive of Coffin-Siris syndrome, association with Mayer-Rokitansky-Küster-Hauser syndrome should be considered and the patient should be evaluated for the same. Both of these syndromes may have a common pathogenesis, as yet unknown. This case report has broad implications, as similar cases in future may give insights into the pathogenesis of both these syndromes.

    Chronic exertional compartment syndrome and medial tibial stress syndrome are uncommon conditions that affect long-distance runners or players involved in team sports that require extensive running. We report 2 cases of bilateral chronic exertional compartment syndrome, with medial tibial stress syndrome in identical twins diagnosed with the use of a Kodiag monitor (B. Braun Medical, Sheffield, United Kingdom) fulfilling the modified diagnostic criteria for chronic exertional compartment syndrome as described by Pedowitz et al, which includes: (1) pre-exercise compartment pressure level >15 mm Hg; (2) 1 minute post-exercise pressure >30 mm Hg; and (3) 5 minutes post-exercise pressure >20 mm Hg in the presence of clinical features. Both patients were treated with bilateral anterior fasciotomies through minimal incision and deep posterior fasciotomies with tibial periosteal stripping performed through longer anteromedial incisions under direct vision followed by intensive physiotherapy resulting in complete symptomatic recovery. The etiology of chronic exertional compartment syndrome is not fully understood, but it is postulated abnormal increases in intramuscular pressure during exercise impair local perfusion, causing ischemic muscle pain. No familial predisposition has been reported to date. However, some authors have found that no significant difference exists in the relative perfusion, in patients, diagnosed with chronic exertional compartment syndrome. Magnetic resonance images of affected compartments have indicated that the pain is not due to ischemia, but rather from a disproportionate oxygen supply versus demand. We believe this is the first report of chronic exertional compartment syndrome with medial tibial stress syndrome in twins, raising the question of whether there is a genetic predisposition to the causation of these conditions.

    Noonan-like syndrome with loose anagen hair is one of the RASopathies characterized by Noonan syndrome-like features with unique ectodermal abnormalities. This syndrome is caused by mutations in the SHOC2 gene. We encountered a patient with moyamoya syndrome associated with Noonan-like syndrome with loose anagen hair presenting with transient ischemic attacks. A 6-year-old girl was diagnosed with Noonan-like syndrome with loose anagen hair because of profound short stature and ectodermal anomalies such as sparse and easily pluckable hair. A heterozygous mutation of c.4A>G (p.S2G) in the SHOC2 gene was identified, and recombinant human growth hormone therapy was initiated at 8 years of age. At age 10, she manifested recurrent left hemiplegia. Moreover, cerebrovascular imaging revealed occlusion or narrowing of both internal carotid arteries and both middle cerebral arteries with distal moyamoya-like vessels. She is treated with aspirin and calcium channel blocker. We describe the first case of Noonan-like syndrome with loose anagen hair associated with moyamoya syndrome, although it has been reported to be associated with a few cases of other RASopathies, including Noonan, cardiofaciocutaneous, and Costello syndromes. This report emphasizes the associations between cerebrovascular anomalies and Noonan-like syndrome with loose anagen hair. Copyright © 2015 Elsevier Inc. All rights reserved.

    Background The incremental prognostic value of assessing the metabolic syndrome has been disputed. Little is known regarding its prognostic value in patients after an acute coronary syndrome. Design and methods The presence of metabolic syndrome (2005 International Diabetes Federation) was assessed at baseline in SOLID-TIMI 52, a trial of patients within 30 days of acute coronary syndrome (median follow-up 2.5 years). The primary endpoint was major coronary events (coronary heart disease death, myocardial infarction or urgent coronary revascularization). Results At baseline, 61.6% ( n = 7537) of patients met the definition of metabolic syndrome, 34.7% (n = 4247) had diabetes and 29.3% had both ( n = 3584). The presence of metabolic syndrome was associated with increased risk of major coronary events (adjusted hazard ratio (adjHR) 1.29, p metabolic syndrome was numerically but not significantly associated with the risk of major coronary events (adjHR 1.13, p = 0.06). Conversely, diabetes was a strong independent predictor of major coronary events in the absence of metabolic syndrome (adjHR 1.57, p metabolic syndrome identified patients at highest risk of adverse outcomes but the incremental value of metabolic syndrome was not significant relative to diabetes alone (adjHR 1.07, p = 0.54). Conclusions After acute coronary syndrome, diabetes is a strong and independent predictor of adverse outcomes. Assessment of the metabolic syndrome provides only marginal incremental value once the presence or absence of diabetes is established.

    Two pairs of siblings are described with proportionate dwarfism due to skeletal hypoplasia of prenatal onset. The head size was normal for age and disproportionately large for height. The patients had a characteristic face different from that seen in the Silver-Russell syndrome. The family data are in accordance with autosomal recessive inheritance. In spite of some similarities, the bulk of clinical and genetic evidence suggests that the described intrauterine growth retardation syndrome is different from the Silver-Russell syndrome and presents an apparently "new" entity which has been designated 3-M syndrome.

    2008-12-01

    Of all patients with Noonan syndrome, 50-90% have one or more congenital heart defects. The most frequent occurring are pulmonary stenosis (PS) and hypertrophic cardiomyopathy. The electrocardiogram (ECG) of a patient with Noonan syndrome often shows a characteristic pattern, with a left axis deviation, abnormal R/S ratio over the left precordium, and an abnormal Q wave. The objective of this study was to determine if these ECG characteristics are an independent feature of the Noonan syndrome or if they are related to the congenital heart defect. A cohort study was performed with 118 patients from two university hospitals in the United States and in The Netherlands. All patients were diagnosed with definite Noonan syndrome and had had an ECG and echocardiography. Sixty-nine patients (58%) had characteristic abnormalities of the ECG. In the patient group without a cardiac defect (n = 21), ten patients had a characteristic ECG abnormality. There was no statistical relationship between the presence of a characteristic ECG abnormality and the presence of a cardiac defect (p = 0.33). Patients with hypertrophic cardiomyopathy had more ECG abnormalities in total (p = 0.05), without correlation with a specific ECG abnormality. We conclude that the ECG features in patients with Noonan syndrome are characteristic for the syndrome and are not related to a specific cardiac defect. An ECG is very useful in the diagnosis of Noonan syndrome; every child with a Noonan phenotype should have an ECG and echocardiogram for evaluation.

    Cerebro-hepato-renal syndrome is a rare disorder that is transmitted by autosomal recessive inheritance. Children with this syndrome present mongoloid facies and severe muscle hypotonic at birth. Scimitar-like knee calcifications are considered a pathognomonic feature of this disorder. We present two patients with Zellweger syndrome, according to the diagnosis suggested by our Radiodiagnostic Service. Our objective is to stress the importance of the radiological findings, which in many cases are decisive in establishing the definitive diagnosis. (Author) 10 refs

  4. Does wastewater discharge have relations with increase of Turner syndrome and Down syndrome?

    Full Text Available The purpose of this study is to examine whether water and air pollutants have a relationship with an increase in the genetic disorders Turner syndrome and Down syndrome, which are caused by congenital chromosomal abnormalities, and to generate a hypothesis about the genetic health effects of environmental pollutants. A panel regression based on random effect was conducted on Korea’s metropolitan councils from 2012 to 2014. The dependent variable was the number of Turner syndrome and Down syndrome cases, and the main independent variables were those regarding the water and air pollution. Air pollutants did not have a significant impact on the number of Turner syndrome and Down syndrome cases; however, the increase in number of wastewater discharge companies did have a significant relationship with the number of cases. The more the number of wastewater discharge companies, the more the number Turner syndrome and Down syndrome cases were observed. Therefore, scientific investigation on water and air pollutants in relation with genetic health effects needs to be performed.

    The skin, hair and nail changes in four distinct ectodermal dysplasia syndromes are compared and reviewed. These syndromes comprise Christ-Siemens-Touraine syndrome; ectrodactyly, ectodermal dysplasia and cleft lip/palate syndrome; ankyloblepharon-ectodermal defects-cleft lip/palate syndrome and Rapp-Hodgkin syndrome. A comprehensive overview of the dermatological signs and symptoms in these syndromes was generated from the database of the Ectodermal Dysplasia Network Germany, the clinical findings in the patients seen in our department and an extensive review of the literature. The findings included abnormalities of skin, sweating, hair and nails. These clinical findings are discussed in relation to the underlying molecular defects known to play a role in these four ectodermal dysplasia syndromes.

    To review the association between orthostatic intolerance syndromes and both joint hypermobility and Ehlers-Danlos syndrome, and to propose reasons for identifying hereditary connective tissue disorders in those with orthostatic intolerance in the context of both clinical care and research. We searched the published peer-reviewed medical literature for papers reporting an association between joint hypermobility or Ehlers-Danlos syndrome and orthostatic intolerance. We identified 10 relevant papers. Although methodological variability between studies introduces some limitations, the published literature consistently identifies a significantly higher prevalence of orthostatic intolerance symptoms in patients with joint hypermobility or Ehlers-Danlos syndrome than in healthy controls, and a significantly higher prevalence of cardiovascular and autonomic abnormalities both at rest and during orthostatic challenge. Postural tachycardia syndrome is the most commonly recognized circulatory disorder. The severity of orthostatic symptoms in those with EDS correlates with impairments in quality of life. There is a strong association between several forms of cardiovascular dysfunction, most notably postural tachycardia syndrome, and joint hypermobility or Ehlers-Danlos syndrome. We propose that recognition of joint hypermobility and Ehlers-Danlos syndrome among those with orthostatic intolerance syndromes has the potential to improve clinical care and the validity of research findings.

    Laron-type dwarfism, which is characterized by the clinical appearance of isolated growth hormone deficiency with elevated serum levels of growth hormone and decreased serum levels of insulin-like growth factor I (IGF-I), has been described in approximately 50 patients. This condition is caused by a deficiency of the cellular receptor for growth hormone, and it is transmitted as an autosomal recessive trait, as indicated by an equal sex distribution and a high rate of consanguinity in affected families. We studied 20 patients (19 females and 1 male, 2 to 49 years of age), from an inbred Spanish population in southern Ecuador, who had the clinical features of Laron-type dwarfism. Seventeen patients were members of two large pedigrees. Among the 13 affected sibships, there were 19 affected and 24 unaffected female siblings and 1 affected and 21 unaffected male siblings. The patients' heights ranged from 10.0 to 6.7 SD below the normal mean height for age in the United States. In addition to the previously described features, 15 patients had limited elbow extensibility, all had blue scleras, affected adults had relatively short extremities, and all four affected women over 30 years of age had hip degeneration. Basal serum concentrations of growth hormone were elevated in all affected children (30 to 160 micrograms per liter) and normal to moderately elevated in the adults. The serum level of growth hormone-binding protein ranged from 1 to 30 percent of normal; IGF-I concentrations were low--less than or equal to 7 micrograms per liter in the children and less than or equal to 66 micrograms per liter in the adults (normal for Ecuadorean women, 98 to 238). Serum levels of IGF-II and growth hormone-dependent IGF-binding protein-3 were also low. We describe an inbred population with a high incidence of growth hormone-receptor deficiency resulting in a clinical picture resembling Laron-type dwarfism but differing principally in showing a marked predominance of affected

    CHAND syndrome is an autosomal recessive disorder characterized by curly hair, ankyloblepharon, and nail dysplasia. Only few patients were reported to date. A homozygous RIPK4 mutation was recently identified by homozygosity mapping and whole exome sequencing in three patients from an expanded consanguineous kindred with a clinical diagnosis of CHAND syndrome. RIPK4 was previously known to be implicated in Bartsocas-Papas syndrome, the autosomal recessive form of popliteal pterygium syndrome. We report here two cases of RIPK4 homozygous mutations in a fetus with severe Bartsocas-Papas syndrome and a patient with CHAND syndrome. The patient with CHAND syndrome harbored the same mutation as the one identified in the family previously reported. We thus confirm the implication of RIPK4 gene in CHAND syndrome in addition to Bartsocas-Papas syndrome and discuss genotype/phenotype correlations. © 2017 Wiley Periodicals, Inc.

  10. Drug treatment of metabolic syndrome.

    The metabolic syndrome is a constellation of risk factors for cardiovascular diseases including: abdominal obesity, a decreased ability to metabolize glucose (increased blood glucose levels and/or presence of insulin resistance), dyslipidemia, and hypertension. Patients who have developed this syndrome have been shown to be at an increased risk of developing cardiovascular disease and/or type 2 diabetes. Genetic factors and the environment both are important in the development of the metabolic syndrome, influencing all single components of this syndrome. The goals of therapy are to treat the underlying cause of the syndrome, to reduce morbidity, and to prevent complications, including premature death. Lifestyle modification is the preferred first-step treatment of the metabolic syndrome. There is no single effective drug treatment affecting all components of the syndrome equally known yet. However, each component of metabolic syndrome has independent goals to be achieved, so miscellaneous types of drugs are used in the treatment of this syndrome, including weight losing drugs, antidiabetics, antihypertensives, antilipemic and anticlothing drugs etc. This article provides a brief insight into contemporary drug treatment of components the metabolic syndrome.

    A pre-term baby girl was born following a pregnancy complicated by severe polyhydramnios at a gestational age of 36 weeks. She was initially suffering from respiratory distress consistent with idiopathic respiratory distress syndrome, and altered electrolyte imbalance with hyponatremia, hypokalemia and hypochloremic metabolic alkalosis. However, during the third week of life when she had dehydration along with significant electrolyte imbalance, Bartter's syndrome was considered which was supported by findings of high renin and aldosterone levels. Treatment was done by correction of electrolytes and dehydration along with indomethacin. The drug was well tolerated. The infant showed correction of electrolyte imbalance. The features of this case suggest an extreme form of Bartter's syndrome presenting from the early days of life. The syndrome is reported because of it's rarity and alerts pediatricians to the antenatal and neonatal variant of Bartter's syndrome. (author)

    Full Text Available Kallmann syndrome is a genetically heterogeneous form of hypogonadotropic hypogonadism caused by gonadotropin-releasing hormone deficiency and characterized by anosmia or hyposmia due to hypoplasia of the olfactory bulbs; osteoporosis and metabolic syndrome can develop due to longstanding untreated hypogonadism. Kallmann syndrome affects 1 in 10 000 men and 1 in 50 000 women. Defects in 17 genes, including KAL1, have been implicated. Kallmann syndrome can be associated with X-linked ichthyosis, a skin disorder characterized by early onset dark, dry, irregular scales affecting the limb and trunk, caused by a defect of the steroid sulfatase gene (STS. Both KAL1 and STS are located in the Xp22.3 region; therefore, deletions in this region cause a contiguous gene syndrome. We report the case of a 32-year-old man with ichthyosis referred for evaluation of excessive height (2.07 m and weight (BMI: 29.6 kg/m2, microgenitalia and absence of secondary sex characteristics. We diagnosed Kallmann syndrome with ichthyosis due to a deletion in Xp22.3, a rare phenomenon.

    Full Text Available There are multiple genetic disorders with known or unknown etiology grouped under obesity syndromes. Inspite of having multisystem involvement and often having a characteristic presentation, the understanding of the genetic causes in the majority of these syndromes is still lacking. The common obesity syndromes are Bardet-Biedl, Prader-Willi, Alstrom, Albright's hereditary osteodystrophy, Carpenter, Rubinstein-Taybi, Fragile X, and Börjeson-Forssman-Lehman syndrome. The list is ever increasing as new syndromes are being added to it. One of the recent additions is MOMO syndrome, with about five such cases being reported in literature. Expanding the spectrum of clinical features, we report the first case of MOMO syndrome from India with lobar variant of holoprosencephaly and cryptorchidism, which have not been reported previously.

    Full Text Available Overlap syndrome, which is known as the coexistence of chronic obstructive pulmonary disease (COPD and obstructive sleep apnea (OSA, was first defined by Flenley. Although it can refer to concomitant occurrence of any of the pulmonary diseases and OSA, overlap syndrome is commonly considered as the coexistence of OSA and COPD. This disease has unique adverse health consequences distinct from either condition alone. Given the high prevalence of each solitary disease, overlap syndrome is also likely to be common and clinically relevant. Despite the fact that overlap syndrome has been described in the literature for nearly 30 years, paucity of evaluations and studies limited the discussion on diagnosis, prevalence, pathophysiology, treatment, and outcomes of this disease. This review article addresses these issues by reviewing several recent studies conducted in Iran or other countries. This review suggests that overlap syndrome has worse outcomes than either disease alone. Our findings accentuated the urgent need for further studies on overlap syndrome and all overlaps between OSA and chronic pulmonary disease to provide a deeper insight into diagnosis and non-invasive treatments of this disease.

    The refeeding syndrome may occur during reintroduction of carbohydrates in malnourished patients. This syndrome is characterized by reduced plasma electrolyte levels, hypophosphataemia being most prevalent. The symptoms can vary from minor symptoms to severe neurological or cardiac symptoms. The pathophysiological mechanism comprises an increase in insulin levels, resulting in shifts of phosphate, potassium and magnesium into the intracellular environment, as well as fluid retention and relative deficiency of vitamin B1. There is growing interest in the screening and treatment of patients with malnutrition, due to which the incidence of refeeding syndrome is probably increasing. Currently, there is no single definition of this syndrome and therefore there is no solid scientific basis for screening and treatment. In this article we describe the rationale for screening and additional laboratory investigations. A prospective, controlled trial is important to define the clinical relevance of the refeeding syndrome and optimize its treatment.

    Metabolic syndrome and the presence of metabolic syndrome components are risk factors for cardiovascular disease (CVD). However, the association between personality traits and metabolic syndrome remains controversial, and few studies have been conducted in East Asian populations. We measured personality traits using the Japanese version of the Eysenck Personality Questionnaire (Revised Short Form) and five metabolic syndrome components-elevated waist circumference, elevated triglycerides, reduced high-density lipoprotein cholesterol, elevated blood pressure, and elevated fasting glucose-in 1322 participants aged 51.1±12.7years old from Kakegawa city, Japan. Metabolic syndrome score (MS score) was defined as the number of metabolic syndrome components present, and metabolic syndrome as having the MS score of 3 or higher. We performed multiple logistic regression analyses to examine the relationship between personality traits and metabolic syndrome components and multiple regression analyses to examine the relationship between personality traits and MS scores adjusted for age, sex, education, income, smoking status, alcohol use, and family history of CVD and diabetes mellitus. We also examine the relationship between personality traits and metabolic syndrome presence by multiple logistic regression analyses. "Extraversion" scores were higher in those with metabolic syndrome components (elevated waist circumference: P=0.001; elevated triglycerides: P=0.01; elevated blood pressure: P=0.004; elevated fasting glucose: P=0.002). "Extraversion" was associated with the MS score (coefficient=0.12, P=0.0003). No personality trait was significantly associated with the presence of metabolic syndrome. Higher "extraversion" scores were related to higher MS scores, but no personality trait was significantly associated with the presence of metabolic syndrome. Copyright © 2018 Elsevier Inc.

The incidence of Sneddon syndrome is 4/1000 000. We present 42-year-old woman with livedo reticularis, recurrence ischaemic cerebrovascular accidents, two repetitive miscarriages and positive anti-2GPi antibodies. Skin biopsy specimens reveal inflammatory changes of small- to medium-sized arteries and subendothelial proliferation and fibrosis. The diagnosis Sneddon syndrome is confirmed by skin biopsy, and MR evidence. We suggest that anti-2GPi antibodies may be pathophysiologically related to the clinical manifestation observed in some patients with Sneddon syndrome.

    Williams syndrome is a rare genetic disorder, that occurs equally in all ethnic groups and both sexes. The diagnosis might be missed during childhood in mild cases. However, establishing the diagnosis is important, not only to find the cause of intellectual disability but to look for cardiovascular, endocrine, psychiatry, urology and other conditions, which can occur at any age in the patients' lifetime. This case report presents the story of 47-year-old woman, who was admitted with haematemesis. During her stay on the ward, in the light of the distinctive facial features, mental retardation, and social behaviour patterns, the possibility of Williams syndrome emerged. Later, the diagnosis was confirmed by genetic analysis. This female is the oldest living patient with Williams syndrome in Hungary. Orv Hetil. 2017; 158(47): 1883-1888.

We analysed data obtained from 6684 adults during the 2013-2015 Korean National Health and Nutrition Examination Survey. After adjustment for related variables, metabolic syndrome ( p metabolic syndrome score ( p metabolic syndrome score with metabolic syndrome score 0 as a reference group showed no significance for metabolic syndrome score 1 [1.061 (95% confidence interval, 0.755-1.490)] and metabolic syndrome score 2 [1.247 (95% confidence interval, 0.890-1.747)], but showed significant for metabolic syndrome score 3 [1.433 (95% confidence interval, 1.010-2.033)] and metabolic syndrome score ⩾ 4 [1.760 (95% confidence interval, 1.216-2.550)]. In addition, the odds ratio of restrictive pulmonary disease of the metabolic syndrome [1.360 (95% confidence interval, 1.118-1.655)] was significantly higher than those of non-metabolic syndrome. Metabolic syndrome and metabolic syndrome score were inversely associated with the predicted forced vital capacity and forced expiratory volume in 1 s values in Korean non-smoking adults. In addition, metabolic syndrome and metabolic syndrome score were positively associated with the restrictive pulmonary disease.

    Tourette Syndrome (TS) is a neurodevelopmental disorder characterized by chronic motor and vocal tics. Although it is a common disorder in childhood, the etiology of Tourette Syndrome has not been fully elucidated yet. Studies, -conducted so far- have revealed differences in neurobiological structures of individuals who suffer from Tourette Syndrome. The objective of this review is to assess etiological and pathophysiological studies in the Tourette Syndrome literature. An electronical search was conducted in PubMed database using the keywords tic disorders, Tourette Syndrome, neurobiology, genetics, neuroimaging and animal models. Research and review studies published between 1985 and 2015, with a selection preference towards recent publications, were reviewed. According to the studies, genetic predisposition hypothesis is considered as a priority. However, a precise genetic disorder associated with Tourette Syndrome has not been found. The evidence from postmortem and neuroimaging studies in heterogenous patient groups and animal studies supports the pathological involvement of cortico-striato-thalamo-cortical (CSTC) circuits in Tourette Syndrome. Consequently, the most emphasized hypothesis in the pathophysiology is the dopaminergic dysfunction in these circuits. Furthermore, these findings of the animal, postmortem and neuroimaging studies have confirmed the neurodevelopmental hypothesis of Tourette Syndrome. In conclusion, more studies are needed to understand the etiology of the disorder. The data obtained from neurobiological studies of the disorder will not only shed light on the way of Tourette Syndrome, but also guide studies on its treatment options.

  18. [Menopause and metabolic syndrome].

    Science.gov (United States)

    Meirelles, Ricardo M R

    2014-03-01

    The incidence of cardiovascular disease increases considerably after the menopause. One reason for the increased cardiovascular risk seems to be determined by metabolic syndrome, in which all components (visceral obesity, dyslipidemia, hypertension, and glucose metabolism disorder) are associated with higher incidence of coronary artery disease. After menopause, metabolic syndrome is more prevalent than in premenopausal women, and may plays an important role in the occurrence of myocardial infarction and other atherosclerotic and cardiovascular morbidities. Obesity, an essential component of the metabolic syndrome, is also associated with increased incidence of breast, endometrial, bowel, esophagus, and kidney cancer. The treatment of metabolic syndrome is based on the change in lifestyle and, when necessary, the use of medication directed to its components. In the presence of symptoms of the climacteric syndrome, hormonal therapy, when indicated, will also contribute to the improvement of the metabolic syndrome.

    2018-01-01

    Abstract Rationale: The life-threatening drug rash with eosinophilia and systemic symptoms (DRESS) syndrome occurs most commonly after exposure to drugs, clinical features mimic those found with other serious systemic disorders. It is rarely associated with thrombotic microangiopathy. Patient concerns: We describe the unique case of a 44-year-old man who simultaneously experienced DRESS syndrome with thrombotic microangiopathy (TMA) after a 5 days treatment with fluindione. Diagnoses: Clinical evaluation leads to the discovery of an underlying lymphangiomatosis, due to a Noonan syndrome. Intervetions: The anticoagulant was withdrawn, and corticosteroids (1 mg/kg/day) and acenocoumarol were started. Outcomes: Clinical improvement ensued. At follow-up the patient is well. Lessons: The association of DRESS with TMA is a rare condition; we believe that the presence of the underlying Noonan syndrome could have been the trigger. Moreover, we speculate about the potential interrelations between these entities. PMID:29642153

    Full Text Available Metabolic syndrome has been defined as a global issue since it affects a lot of people. Numerous factors are involved in metabolic syndrome development. It has been described that metabolic syndrome has negative consequences on health. Consequently, a lot of treatments have been proposed to palliate it such as drugs, surgery or life style changes where nutritional habits have shown to be an important point in its management. The current study reviews the literature existing about the actual epidemiology of metabolic syndrome, the components involucrate in its appearance and progression, the clinical consequences of metabolic syndrome and the nutritional strategies reported in its remission. A bibliographic search in PubMed and Medline was performed to identify eligible studies. Authors obtained that metabolic syndrome is present in population from developed and undeveloped areas in a huge scale. Environmental and genetic elements are involucrate in metabolic syndrome development. Metabolic syndrome exponentially increased risk of cardiovascular disease, some types of cancers, diabetes mellitus type 2, sleep disturbances, etc. Nutritional treatments play a crucial role in metabolic syndrome prevention, treatment and recovery.

    The aim of this study is to compare metabolic syndrome with syndrome Z growing epidemic in terms of risk factors, demographic variables, and gender differences in our large cohort at southeastern area in Turkey. Data of patients admitted to sleep clinic in University of Gaziantep from January 2006 to January 2011 were retrospectively evaluated. ATP III and JNC 7 were used for defining metabolic syndrome and hypertension. Data of 761 patients were evaluated. Hypertension, diabetes mellitus, coronary artery disease, pulmonary hypertension, and left ventricular hypertrophy were more common in patients with syndrome Z than in patients without metabolic syndrome. Age, waist/neck circumferences, BMI, triglyceride, glucose, and Epworth sleepiness scale score were detected higher, whereas the minimum oxygen saturation during sleep was lower in patients with syndrome Z. Metabolic syndrome was more common in sleep apneic subjects than in controls (58 versus 30 %). Female sleep apneics showed higher rate of metabolic syndrome than those of males (74 versus 52 %). Hypertension, diabetes mellitus, coronary artery disease, and left ventricular hypertrophy were detected higher in males with syndrome Z than in males without metabolic syndrome. Snoring and excessive daytime sleepiness were detected higher in females with syndrome Z than in females without metabolic syndrome. Systemic/pulmonary hypertension, diabetes mellitus, and left ventricular hypertrophy were more common in females with syndrome Z than in females without metabolic syndrome. Complaints of headache and systemic/pulmonary hypertension were more common among females than males with syndrome Z. Female syndrome Z patients had lower minimum oxygen saturation than male patients with syndrome Z. Metabolic syndrome in sleep apneic patients is more prevalent than in controls. All metabolic syndrome parameters were significantly different among obstructive sleep apneic patients with respect to gender with more severe

    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.

    In spite of a few shortcomings such as over diagnosis and over treatment, syndromic management is a recommended practice in India for sexually transmitted infections (STIs). This study tries to find out the efficacy of syndromic management measured as symptomatic improvement in females with vaginal discharge syndrome. The objective of the study is to find out the effectiveness of syndromic management in terms of symptomatic improvement among females with vaginal discharge syndrome. A longitudinal study was conducted in Gynecology Department of Tertiary Care Hospital including 180 symptomatic females having vaginal discharge syndrome. Demographic profile, presenting complaints, menstrual history, obstetric history, partner history, and contraceptive history were noted. This was followed by clinical examination and specimen collection for laboratory tests and blood tests to find out type of STI including viral STI such as human immunodeficiency virus (HIV), herpes simplex virus (HSV), and hepatitis B surface antigen (HBsAg). Treatment was given according to syndromic management on the same day. All the participants were asked to come for follow-up after 15 days and their improvement in symptoms was noted as complete improvement, some improvement or no improvement on a five point scale. 63.9% cases showed complete improvement, while 36.1% showed some improvement. None of the patients was without any improvement. Vaginal discharge syndrome was most common between 20 and 30 years (43.4%), and 67.8% of symptomatic females with vaginal discharge syndrome belonged to the lower socioeconomic group. HSV infection was the most common (15%) associated viral infection with vaginal discharge syndrome, while hepatitis B infection was the least common (0.5%). HIV was reactive in 2.8% cases only. Syndromic management was found to be effective in relieving symptoms in most of the cases of vaginal discharge syndrome.

    Full Text Available Abstract Introduction Prune belly syndrome is a rare congenital anomaly of uncertain aetiology almost exclusive to males. The association between prune belly syndrome and Down syndrome is very rare. Case presentation A 4-month-old Egyptian boy was admitted to our institute for management of acute bronchiolitis. He was born at full term by normal vaginal delivery. His mother, a 42-year-Egyptian villager with six other children, had no antenatal or prenatal care. On examination, the boy was found to be hypotonic. In addition to features of Down syndrome, karyotyping confirmed the diagnosis of trisomy 21. Ultrasound examination of the abdomen showed bilateral gross hydronephrosis with megaureter. Micturating cystourethrography showed grade V vesicoureteric reflux bilaterally with no urethral obstruction. Serum creatinine concentration was 90 μmol/litre, serum sodium was 132 mmol/litre and serum potassium was 5.9 mmol/litre. Conclusion We report an Egyptian infant with Down syndrome and prune belly syndrome. The incidence of this association is unknown. Routine antenatal ultrasonography will help in discovering renal anomalies which can be followed postnatally. Postnatal detection of prune belly syndrome necessitates full radiological investigation to detect any renal anomalies. Early diagnosis of this syndrome and determining its optimal treatment are very important in helping to avoid its fatal course.

    A stillborn baby boy had findings of severe constitutional dwarfism with short limbs, short ribs, and polydactyly that were consistent with Naumoff (type III) short-rib polydactyly syndrome. He also had additional congenital anomalies, including cleft palate, notching of the upper lip, small tongue with accessory sublingual tissue. These oral and pharyngeal anomalies were consistent with Mohr (type II) oral-facial-digital syndrome. We suggest the stillborn infant represented a compound of Naumoff short-rib polydactyly syndrome (SRPS-III) and Mohr oral-facial-digital syndrome (OFDS-II). (orig.)

    Capgras syndrome is characterized by a delusion of impostors who are thought to be physically similar but psychologically distinct from the misidentified person. This syndrome is generally thought to be relatively rare. Most of our knowledge about Capgras syndrome derives from single case studies and small series of cases usually from diagnostically heterogeneous groups. In this article, a series of 31 patients suffering from both paranoid schizophrenia and Capgras syndrome is described. Issues pertaining to the phenomenology of Capgras syndrome, the possible relation between Capgras syndrome and other delusional misidentification syndromes, and a neurobiological hypothesis aimed at explaining Capgras syndrome are discussed.

    2013-01-01

    Summary Introduction: Eagle's syndrome is characterized by cervicopharyngeal signs and symptoms associated with elongation of the styloid apophysis. This elongation may occur through ossification of the stylohyoid ligament, or through growth of the apophysis due to osteogenesis triggered by a factor such as trauma. Elongation of the styloid apophysis may give rise to intense facial pain, headache, dysphagia, otalgia, buzzing sensations, and trismus. Precise diagnosis of the syndrome is difficult, and it is generally confounded by other manifestations of cervicopharyngeal pain. Objective: To describe a case of Eagle's syndrome. Case Report: A 53-year-old man reported lateral pain in his neck that had been present for 30 years. Computed tomography (CT) of the neck showed elongation and ossification of the styloid processes of the temporal bone, which was compatible with Eagle's syndrome. Surgery was performed for bilateral resection of the stylohyoid ligament by using a transoral and endoscopic access route. The patient continued to present pain laterally in the neck, predominantly on his left side. CT was performed again, which showed elongation of the styloid processes. The patient then underwent lateral cervicotomy with resection of the stylohyoid process, which partially resolved his painful condition. Final Comments: Patients with Eagle's syndrome generally have a history of chronic pain. Appropriate knowledge of this disease is necessary for adequate treatment to be provided. The importance of diagnosing this uncommon and often unsuspected disease should be emphasized, given that correct clinical-surgical treatment is frequently delayed. The diagnosis of Eagle's syndrome is clinical and radiographic, and the definitive treatment in cases of difficult-to-control pain is surgical. PMID:25992033

    Kraft, Michael D; Btaiche, Imad F; Sacks, Gordon S

    2005-12-01

    Refeeding syndrome describes a constellation of metabolic disturbances that occur as a result of reinstitution of nutrition to patients who are starved or severely malnourished. Patients can develop fluid and electrolyte disorders, especially hypophosphatemia, along with neurologic, pulmonary, cardiac, neuromuscular, and hematologic complications. We reviewed literature on refeeding syndrome and the associated electrolyte abnormalities, fluid disturbances, and associated complications. In addition to assessing scientific literature, we also considered clinical experience and judgment in developing recommendations for prevention and treatment of refeeding syndrome. The most important steps are to identify patients at risk for developing refeeding syndrome, institute nutrition support cautiously, and correct and supplement electrolyte and vitamin deficiencies to avoid refeeding syndrome. We provide suggestions for the prevention of refeeding syndrome and suggestions for treatment of electrolyte disturbances and complications in patients who develop refeeding syndrome, according to evidence in the literature, the pathophysiology of refeeding syndrome, and clinical experience and judgment.

    Heterogeneity of Waardenburg syndrome is demonstrated in a review of 1,285 patients from the literature and 34 previously unreported patients in five families in the Netherlands. The syndrome seems to consist of two genetically distinct entities that can be differentiated clinically: type I, Waardenburg syndrome with dystopia canthorum; and type II, Waardenburg syndrome without dystopia canthorum. Both types have an autosomal dominant mode of inheritance. The incidence of bilateral deafness in the two types of the syndrome was found in one-fourth with type I and about half of the patients with type II. This difference has important consequences for genetic counseling. Images Fig. 7 Fig. 8 Fig. 9 PMID:331943

    2006-01-01

    We present a rare case of bilateral crocodile tears syndrome (CTS) in the course of Melkersson-Rosenthal syndrome. Melkersson-Rosenthal syndrome is characterised by a triad of recurrent orofacial swelling, relapsing facial paralysis, and fissured tongue. The classic triad is infrequent and oligosymptomatic variants are seen more frequently. CTS is a rare complication of facial nerve paralysis characterised by inappropriate lacrimation on the side of the palsy in response to salivary stimuli. It results from aberrant reinnervation of the lacrimal gland by salivary parasympathetic fibres. The therapeutic approach for an acute bout of Melkersson-Rosenthal syndrome consists mainly of steroid administration. CTS management is composed of anticholinergic drugs and surgical procedures. Botulin toxin injection into the lacrimal gland is the most modern therapeutic option. In the case presented CTS developed in a 50-year-old man after 5 incidents of facial palsy due to Melkersson-Rosenthal syndrome. The case deserves attention due to the rarity of the observed symptoms and signs.

    Full Text Available Background & aims This study compared gesture rate and purpose in participants with Down syndrome and fragile X syndrome, and the impact of autism spectrum disorder symptoms on each syndrome. Methods Twenty individuals with fragile X syndrome and 20 individuals with Down syndrome between nine and 22 years of age participated in this study. We coded gesture rate and purpose from an autism spectrum disorder evaluation, the Autism Diagnostic Observation Schedule – Second Edition. Results We did not find between-group differences (Down syndrome compared to fragile X syndrome in gesture rate or purpose. Notably, as autism spectrum disorder symptoms increased, the group with Down syndrome produced a lower rate of gestures, but used gestures for the same purpose. Gesture rate did not change based on autism spectrum disorder symptoms in the participants with fragile X syndrome, but as autism spectrum disorder symptoms increased, the participants with fragile X syndrome produced a larger proportion of gestures to regulate behavior and a smaller proportion for joint attention/social interaction. Conclusions Overall, the amount or purpose of gestures did not differentiate individuals with Down syndrome and fragile X syndrome. However, the presence of autism spectrum disorder symptoms had a significant and unique impact on these genetic disorders. In individuals with Down syndrome, the presence of more autism spectrum disorder symptoms resulted in a reduction in the rate of gesturing, but did not change the purpose. However, in fragile X syndrome, the rate of gestures remained the same, but the purpose of those gestures changed based on autism spectrum disorder symptoms. Implications Autism spectrum disorder symptoms differentially impact gestures in Down syndrome and fragile X syndrome. Individuals with Down syndrome and more autism spectrum disorder symptoms are using gestures less frequently. Therefore, clinicians may need to consider children with

    Full Text Available Costello syndrome is a rare, distinctive, multiple congenital anomaly syndrome, characterized by soft, loose skin with deep palmar and plantar creases, loose joints, distinctive coarse facial features and skeletal and cardiac abnormalities. The affected patients have a predisposition to develop malignancy, developmental delays and mental retardation. Recently, a 7-year-old male child born to normal nonconsanguineous parents presented to us with abnormal facial features, arrhythmia, mitral valve dysfunction and growth retardation. His cutaneous examination revealed lax and pigmented skin over hands and feet with deep creases, acanthosis nigricans and short curly hairs. Its differentiation from other syndromes with similar clinical features is discussed in this article.

Participants were asked to complete psychometric tests: Body Shape Questionnaire, Beck Depression Inventory, Eating Disorder Inventory–2, and Temperament and Character Inventory. Data were submitted to cluster analysis. Results Illness denial (63% and alexithymia (54.6% resulted to be the most common syndromes in our sample. Cluster analysis identified three groups: moderate psychosomatic group (49%, somatization group (26%, and severe psychosomatic group (25%. The first group was mainly represented by AN-R patients reporting often only illness denial and alexithymia as DCPR syndromes. The second group showed more severe eating and depressive symptomatology and frequently DCPR syndromes of the somatization cluster. Thanatophobia DCPR syndrome was also represented in this group. The third group reported longer duration of illness and DCPR syndromes were highly represented; in particular, all patients were found to show the alexithymia DCPR syndrome. Conclusions These results highlight the need of a deep assessment of psychosomatic syndromes in AN. Psychosomatic syndromes correlated differently with both severity of eating symptomatology and duration of illness: therefore, DCPR could be effective to achieve tailored treatments.

  9. The Marfan syndrome genetics

    2005-05-01

    Full Text Available Background: The Marfan syndrome is an autosomal dominant heritable disorder of connective tissue. It is caused by mutations in the fibrillin-1 gene encoding glycoprotein fibrillin-1, a component of microfibrils of extracellular matrix. Patients with Marfan syndrome show wide spectra of clinical signs, primarily on skeletal, cardiovascular and ocular organ systems. Cardiovascular complications (especially aortic aneurysm and aortic dissection are the most common cause of mortality of Marfan syndrome patients. Discovering genotype-phenotype correlations is complicated because of the large number of mutations reported as well as clinical heterogeneity among individuals with the same mutation. Despite the progress in the knowledge of the molecular nature of Marfan syndrome the diagnosis is still based mainly on the clinical features in the different body systems.Conclusions: Early identification of patient with Marfan syndrome is of considerable importance because of appropriate treatment that can greatly improve life expectancy. Unfortunately, despite the improvement of diagnostic methods, medical and surgical therapy, the mortality due to undiagnosed Marfan syndrome is still high. The present article reviews the molecular genetic studies of Marfan syndrome since the discovery of the mutations in the fibrillin-1 gene.

    In Turner syndrome, cardiovascular complications are the most important causes of early mortality. Congenital cardiovascular abnormalities are found in approximately one third of Turner syndrome patients. Developments in diagnosis and treatment have decreased the rate of mortality related to these abnormalities. In recent years, many papers have mentioned that coronary artery disease developing at early ages in patients with Turner syndrome causes sudden deaths. The patient, a 27-year-old female was admitted to the emergency room with chest pain at rest. She was diagnosed with Turner Syndrome in her teenage years due to amenorrhea. Patients with ECG changes and cardiac enzyme elevations were treated with acute coronary syndrome. The young woman with Turner Syndrome have several risk factors for early Coronary Artery Disease development. In such cases, dramatic results like sudden death or heart attack at an early age may occur in cases of insufficient follow-up and treatment.

    Rheumatoid arthritis has manifestations in various organs including ophthalmic involvement. The present study evaluates prevalence of dry eye and secondary Sjogren's syndrome using salivary scintigraphy which has not been used in previous reports. To evaluate the prevalence of secondary Sjogren's syndrome in patients with rheumatoid arthritis, including clinical characteristics and dry eye, compared with non-Sjogren's syndrome. Descriptive cross sectional study Sixty-one patients with rheumatoid arthritis were recruited at Siriraj Hospital during March 2009-September 2010 and filled in the questionnaires about dry eye for Ocular Surface Disease Index (OSDI) with a history taking of associated diseases, medications, duration of symptoms of dry eyes and dry mouth. The Schirmer I test without anesthesia, tear break-up time, rose bengal staining score, severity of keratitis and salivary scintigraphy were measured and analyzed. Prevalence of secondary Sjogren's syndrome and dry eye were 22.2% (95% CI 15.4 to 30.9) and 46.7% (95% CI 38.0 to 55.6), respectively. Dry eye interpreted from OSDI, Schirmer 1 test, tear break-up time and rose bengal staining was 16.4%, 46.7%, 82% and 3.3% respectively. Fifty-two percent of patients had a history of dry eye and dry mouth with mean duration 27.4 and 29.8 months, respectively. Superficial punctate keratitis and abnormal salivary scintigraphy were found in 58.2% and 77.8%. Duration of rheumatoid arthritis, erythrocyte sedimentation rate were not correlated with secondary Sjogren's syndrome. Dry eye from OSDI with secondary Sjogren's syndrome (33.3%) compared with non-Sjogren's syndrome (9.5%) was significant difference (p = 0.008). Adjusted odds ratio for secondary Sjogren's syndrome in OSDIL score > 25 was 13.8 (95% CI 2.6 to 73.8, p = 0.002) compared to OSDI score dry eye syndrome and secondary Sjogren's syndrome in rheumatoid arthritis was crucial for evaluation of their severity and proper management.

    To explore the composition characteristics of traditional Chinese medicine (TCM) syndromes in patients with acute ischemic stroke of yin or yang syndrome by investigating the characteristics of TCM syndromes at different periods after onset. One thousand two hundred and forty-six patients with acute ischemic stroke were admitted in twenty hospitals. According to the "diagnostic criteria of syndrome differentiation of stroke", the characteristics of syndromes in the patients were investigated at the periods of 1-3 days, 4-10 days and 11-30 days after they had ischemic stroke. General distribution of six basic syndromes was compared between the patients with yin syndrome and the patients with yang syndrome at the three periods. The six basic syndromes were wind syndrome, pathogenic fire syndrome, phlegm syndrome, blood stasis syndrome, qi deficiency syndrome, and syndrome of yin deficiency and yang hyperactivity. The percentages of wind, pathogenic fire, and phlegm syndromes in the patients were decreased at the period of 11-30 days as compared with the period of 1-3 days (87.1% vs 79.3%, 52.1% vs 38.7% and 67.1% vs 57.4% respectively, P0.05). There were no differences in the distribution of yin and yang syndromes among the three periods (P>0.05). The percentages of syndromes of wind, pathogenic fire, phlegm, and yin deficiency and yang hyperactivity were higher (Pfour or five syndromes were higher, and the percentages of single-syndromes and complex syndromes of two syndromes were lower in patients with yang syndrome than in patients with yin syndrome (P<0.05, P<0.01). The most frequent complex syndromes in patients with yin syndrome were complex syndrome of wind, phlegm, blood stasis and qi deficiency, and complex syndrome of wind, phlegm and qi deficiency; while the most frequent complex syndromes in patients with yang syndrome were complex syndrome of wind, pathogenic fire, phlegm and qi deficiency, and complex syndrome of wind, pathogenic fire and phlegm.

  14. Pfeiffer syndrome

    Directory of Open Access Journals (Sweden)

    Fryns Jean-Pierre

    2006-06-01

    Full Text Available Abstract Pfeiffer syndrome is a rare autosomal dominantly inherited disorder that associates craniosynostosis, broad and deviated thumbs and big toes, and partial syndactyly on hands and feet. Hydrocephaly may be found occasionally, along with severe ocular proptosis, ankylosed elbows, abnormal viscera, and slow development. Based on the severity of the phenotype, Pfeiffer syndrome is divided into three clinical subtypes. Type 1 "classic" Pfeiffer syndrome involves individuals with mild manifestations including brachycephaly, midface hypoplasia and finger and toe abnormalities; it is associated with normal intelligence and generally good outcome. Type 2 consists of cloverleaf skull, extreme proptosis, finger and toe abnormalities, elbow ankylosis or synostosis, developmental delay and neurological complications. Type 3 is similar to type 2 but without a cloverleaf skull. Clinical overlap between the three types may occur. Pfeiffer syndrome affects about 1 in 100,000 individuals. The disorder can be caused by mutations in the fibroblast growth factor receptor genes FGFR-1 or FGFR-2. Pfeiffer syndrome can be diagnosed prenatally by sonography showing craniosynostosis, hypertelorism with proptosis, and broad thumb, or molecularly if it concerns a recurrence and the causative mutation was found. Molecular genetic testing is important to confirm the diagnosis. Management includes multiple-staged surgery of craniosynostosis. Midfacial surgery is performed to reduce the exophthalmos and the midfacial hypoplasia.

    The RASopathies are a family of developmental disorders caused by heritable defects of the RAS/MAPK signaling pathway. While the postnatal presentation of this group of disorders is well known, the prenatal and neonatal findings are less widely recognized. We report on the perinatal presentation of 10 patients with Noonan syndrome (NS), nine with Cardiofaciocutaneous syndrome (CFCS) and three with Costello syndrome (CS), in conjunction with the results of a comprehensive literature review. The majority of perinatal findings in NS, CS, and CFCS are shared: polyhydramnios; prematurity; lymphatic dysplasia; macrosomia; relative macrocephaly; respiratory distress; hypotonia, as well as cardiac and renal anomalies. In contrast, fetal arrhythmia and neonatal hypoglycemia are relatively specific to CS. NS, CS, and CFCS should all be considered as a possible diagnosis in pregnancies with a normal karyotype and ultrasound findings of a RASopathy. Recognition of the common perinatal findings of these disorders should facilitate both their prenatal and neonatal diagnosis. © 2014 Wiley Periodicals, Inc.

    The etiology of perceptive deafness, especially the congenital variety, requires investigation. The presence of a variety of signs associated with deafness constitutes an "associated syndrome" and helps to define a possible genetic origin. These syndromes only represent a small percentage of overall causes of deafness in children, since at most they account for only 10% of cases. Certain syndromes are encountered more often or are well known, others are extremely rare or have only been described recently. The authors report six of these very rare syndromes discovered among their patients: a KID syndrome, a Leopard syndrome, a Norrie syndrome, a Jervell and Lange Nielsen syndrome, a recently described entity called CEE with deafness and an External Neuro-Cochleo-Pancreatic syndrome which would not appear to have been previously described.

    Gorlin-Goltz syndrome or nevoid basal cell carcinoma syndrome (NBCCS) comprises multiple basal cell carcinomas, keratocysts of the jaw, palmar/plantar pits, spine and rib anomalies, calcifications of the falx cerebri etc. The diagnosis is made according to clinical criteria (Kimonis Criteria) and genetic ones. We studied one family where father and then his sun resulted affected by each syndrome. Gorlin-Goltz syndrome is a rare disease diagnosed according to clinical criteria sometimes difficult to integrate. The family case we presented shows how you can get diagnosis even in older age and after numerous surgeries. Patients should be given special attention and therefore should be monitorized and need multidisciplinary treatments continued in time, even a trivial change of signs and symptoms may be an important indicator of a precipitating event which puts the patient's life under threat.

    Full Text Available Audience: This scenario was developed to educate emergency medicine residents on the diagnosis and management of a pediatric patient with toxic shock syndrome. The case is also appropriate for teaching of medical students and advanced practice providers, as well as a review of the principles of crisis resource management, teamwork, and communication. Introduction: Toxic shock syndrome is a low-frequency, high-acuity scenario requiring timely identification and aggressive management. If patients suffering from this condition are managed incorrectly, they may progress into multi-organ dysfunction and potentially death. Toxic shock syndrome has been associated with Streptococcus and Staphylococcus aureus (Staph. Approximately half of Staph cases are associated with menstruation, which was first described in the 1970s-1980s and was associated with the use of absorbent tampons.1 Group A Streptococcus may cause complications such as necrotizing fasciitis and gangrenous myositis.2 Pediatric patients may present critically ill from toxic shock syndrome. Providers need to perform a thorough history and physical exam to discern the source of infection. Management requires aggressive care with antibiotics and IV fluids. Objectives: By the end of this simulation session, the learner will be able to: 1 Recognize toxic shock syndrome. 2 Review the importance of a thorough physical exam. 3 Discuss management of toxic shock syndrome, including supportive care and the difference in antibiotic choices for streptococcal and staphylococcal toxic shock syndrome. 4 Appropriately disposition a patient suffering from toxic shock syndrome. 5 Communicate effectively with team members and nursing staff during a resuscitation of a critically ill patient. Method: This session was conducted using high-fidelity simulation, followed by a debriefing session and lecture on toxic shock syndrome.

    Kartagener's Syndrome or Immotile Cilia Syndrome, a variant of Primary Ciliary Dyskinesia (PCD), is a rare autosomal recessive genetic disorder caused by defect in the tiny hair like structure, the cilia lining the respiratory tract (upper and lower), sinuses, eustachian tubes, middle ear and fallopian tubes. Here electron microscopy shows abnormal arrangement of ciliary tubules and patients with Kartagener's syndrome has an absence of dynein arms at the base of the cilia. The inability of cilia to move results in inadequate clearance of bacteria from the air passages, resulting in an increased risk of infection and causing bronchiectasis. Another result of ciliary immobility is infertility. A 60 years old lady was diagnosed as a case of Kartagener's syndrome. She had history of chronic cough for 20 years, irregular fever for 20 years and occasional shortness of breath for 5 years. Relevant investigations revealed dextrocardia, situs inversus, bilateral maxillary sinusitis with non pneumatised frontal sinus and bronchiectasis. She was treated with low concentration oxygen inhalation, antibiotic, bronchodilator, chest physiotherapy including postural drainage, vitamins and other supportive treatment.

    Screening for DNA mismatch repair (MMR) deficiency in colorectal and endometrial carcinomas identifies patients at risk for Lynch syndrome. Some patients with MMR-deficient tumors have no evidence of a germline mutation and have been described as having Lynch-like syndrome. We compared the clinicopathological features of colorectal and endometrial carcinomas in patients with Lynch-like syndrome and Lynch syndrome. Universal screening identified 356 (10.6%) of 3352 patients with colorectal carcinoma and 72 (33%) of 215 patients with endometrial carcinoma with deficient DNA MMR. Sixty-six patients underwent germline mutation analysis with 45 patients (68%) having evidence of a germline MMR gene mutation confirming Lynch syndrome and 21 patients (32%) having Lynch-like syndrome with no evidence of a germline mutation. Most patients with Lynch-like syndrome had carcinoma involving the right colon compared to patients with Lynch syndrome (93% versus 45%; P Lynch syndrome confirmed by germline mutation analysis. Synchronous or metachronous Lynch syndrome-associated carcinoma was more frequently identified in patients with Lynch syndrome compared to Lynch-like syndrome (38% versus 7%; P = .04). There were no significant differences in clinicopathological variables between patients with Lynch-like syndrome and Lynch syndrome with endometrial carcinoma. In summary, 32% of patients with MMR deficiency concerning Lynch syndrome will have Lynch-like syndrome. Our results demonstrate that patients with Lynch-like syndrome are more likely to have right-sided colorectal carcinoma, less likely to have synchronous or metachronous Lynch syndrome-associated carcinoma, and less likely to demonstrate isolated loss of MSH6 expression within their tumor.

    2003-06-01

    Clinical and genetic characteristics are presented of 2 patients from a Dutch Usher syndrome type III family who have a new homozygous USH3 gene mutation: 149-152delCAGG + insTGTCCAAT. One individual (IV:1) is profoundly hearing impaired and has normal vestibular function and retinitis punctata albescens (RPA). The other individual is also profoundly hearing impaired, but has well-developed speech, vestibular areflexia, and retinitis pigmentosa sine pigmento (RPSP). These findings suggest that Usher syndrome type III can be clinically misdiagnosed as either Usher type I or II; that Usher syndrome patients who are profoundly hearing impaired and have normal vestibular function should be tested for USH3 mutations; and that RPA and RPSP can occur as fundoscopic manifestations of pigmentary retinopathy in Usher syndrome.

    Full Text Available Ehlers-Danlos syndrome is a group of clinically and genetically heterogeneous inherited connective tissue disorders with widespread manifestations. The prevalence of this syndrome is 1:5000 worldwide without gender, racial or ethnic associations. This syndrome is characterized by joint hypermobility, dermal hyperelasticity and tissue fragility caused by mutations in genes encoding collagen type I, III, V and enzymes involved in the posttranslational modifications of collagen. The oral manifestations include increased mucosal fragility, delayed wound healing, early onset generalized periodontitis and temporomandibular joint hypermobility. Children presenting with this syndrome are often misdiagnosed for hematological problem as they present with bruising, malignancy and/or child abuse. A thorough assessment of the patient is, therefore, essential for early diagnosis and patient referral. This paper reviews current literature, oral manifestations, diagnostic investigations and effective dental management.

    Chiappedi, Matteo; de Vincenzi, Silvia; Dolci, Roberta; De Luca, Sara; Bejor, Maurizio

    2011-11-05

    To the best of our knowledge, this is the first report of a comorbidity between Gilles de la Tourette's syndrome and 47 (XXX) syndrome. The clinical picture of Gilles de la Tourette's Syndrome is well described, while 47 (XXX) syndrome is much more rare and has a broader spectrum of possible phenotypic presentations. An Italian Caucasian girl was referred at the age of 11 to our Rehabilitation Center for anxiety and learning difficulties. The girl had already been diagnosed as having 47(XXX) syndrome; she had some rather typical features of the chromosomal abnormality, but she also showed a high level of anxiety and the presence of motor and vocal tics. When an accurate history was taken, a diagnosis of Gilles de la Tourette's Syndrome emerged. The possible interaction between peculiar features of these two syndromes in terms of neuropsychological and affective functioning is both interesting for the specific case and to hypothesize models of rehabilitation for patients with one or both syndromes. Executive functions are specifically reduced in both syndromes, therefore it might be hard to discriminate the contribution of each one to the general impairment; the same applies to anxiety. Moreover, mental retardation (with a significantly lower verbal cognitive functioning) poses relevant problems when suggesting cognitive behavioral or psychoeducational rehabilitative approaches.

    Noonan syndrome (NS) is an autosomal dominant disorder with vast heterogeneity in clinical and genetic features. Various symptoms have been reported for this abnormality such as short stature, unusual facial characteristics, congenital heart abnormalities, developmental complications, and an elevated tumor incidence rate. Noonan syndrome shares clinical features with other rare conditions, including LEOPARD syndrome, cardio-facio-cutaneous syndrome, Noonan-like syndrome with loose anagen hair, and Costello syndrome. Germline mutations in the RAS-MAPK (mitogen-activated protein kinase) signal transduction pathway are responsible for NS and other related disorders. Noonan syndrome diagnosis is primarily based on clinical features, but molecular testing should be performed to confirm it in patients. Due to the high number of genes associated with NS and other RASopathy disorders, next-generation sequencing is the best choice for diagnostic testing. Patients with NS also have higher risk for leukemia and specific solid tumors. Age-specific guidelines for the management of NS are available.

    2016-09-01

    Full Text Available Painful disorders in the maxillofacial region are common in dental practice. Most of these conditions are not properly diagnosed because of inadequate knowledge of craniofacial and cervico-pharyngeal syndromes such as Eagle Syndrome. The aim of this review is to describe the general aspects, diagnosis and treatment of Eagle syndrome. Eagle syndrome or stylohyoid syndrome was first described by Watt W. Eagle in 1937. It was defined as orofacial pain related to the elongation of the styloid process and ligament stylohyoid calcification. The condition is accompanied by symptoms such as dysphonia, dysphagia, sore throat, glossitis, earache, tonsillitis, facial pain, headache, pain in the temporomandibular joint and inability to perform lateral movements of the neck. Diagnosis and treatment of Eagle syndrome based on symptoms and radiographic examination of the patient will determine the need for surgical or nonsurgical treatment. Eagle syndrome is a complex disorder demanding a thorough knowledge of its signs and symptoms to make a correct diagnosis and provide an appropriate subsequent treatment. Disseminating information about this syndrome among medical-dental professionals is essential to provide adequate dental care to patients.

    Full Text Available Traditional Chinese medicine (TCM; 中醫 zhōng yī syndrome groups are based on the symptoms of human diseases and guide the use of Chinese herbs. The aim of this study was to examine the effects of TCM syndrome groups on biochemical characteristics and quality of life (QOL in women with metabolic syndrome (MS. Among the 1080 registered female patients screened at our outpatient clinic, a total of 322 women aged between 18 and 65 years and meeting the requirements of MS were enrolled. All the patients were asked to fill out a questionnaire on metabolic TCM syndrome groups and a questionnaire on the QOL, the Medical Outcomes Study (MOS Short Form-12 (SF-12. Data of biochemical characteristics were collected at the same time. The present study showed MS women in TCM syndrome groups had significantly lower physical and mental component scores in SF-12 compared with those not in TCM syndrome groups. We also found MS patients in TCM syndrome groups, except Kidney Deficiency syndrome, showed higher body mass indexes, waist circumference, and hip circumference. However, there was almost no difference in most biochemical characteristics between TCM syndrome groups. The MS patients diagnosed as belonging to TCM syndrome groups had poor QOL.

  13. Nelson syndrome: definition and management.

    Science.gov (United States)

    Barber, T M; Adams, E; Wass, J A H

    2014-01-01

    Nelson syndrome is an important complication of treatment with total bilateral adrenalectomy (TBA) for patients with refractory Cushing's disease. Although early cases of Nelson syndrome often presented with the clinical features of large sellar masses, the modern face of Nelson syndrome has changed primarily due to earlier detection (with highly resolved magnetic resonance imaging (MRI) and sensitive ACTH assays) and greater awareness of the condition, resulting in reduced morbidity and mortality. Although lack of administration of neoadjuvant pituitary radiotherapy post-TBA surgery may predict future development of Nelson syndrome, other predictive factors remain controversial. Therefore, Nelson syndrome should be screened for closely and long-term in all patients with a history of Cushing's disease and TBA. The diagnosis of Nelson syndrome remains controversial, and the pathogenesis of this condition is incompletely understood. Current hypotheses include the "released negative feedback" mechansism (residual pituitary corticotropinoma cells are "released" from the negative feedback effects of cortisol following TBA), and the "aggressive corticotropinoma" mechanism (Nelson syndrome is most likely to develop in those patients with refractory treatments - including TBA - for an underlying aggressive corticotropinoma). Effective management of Nelson syndrome with pituitary surgery and radiotherapy is often a challenge. Other therapies (such as Gamma Knife surgery and temozolomide) play an important role and merit further research into their efficacy and placement in the management pathway of Nelson syndrome. © 2014 Elsevier B.V.

    2017-10-01

    Fragile-X-syndrome is the most common cause of inherited intellectual disability. Epilepsy is reported to occur in 10-20% of individuals with Fragile-X-syndrome. A frequent seizure/electroencephalogram (EEG) pattern resembles that of benign rolandic epilepsy. We describe the clinical features, EEG findings and evolution in three patients affected by Fragile-X-syndrome and epilepsy mimicking Panayiotopoulos syndrome. Age at seizure onset was between 4 and about 7 years. Seizures pattern comprised a constellation of autonomic symptoms with unilateral deviation of the eyes and ictal syncope. Duration of the seizures could be brief or lengthy. Interictal EEGs revealed functional multifocal abnormalities. The evolution was benign in all patients with seizures remission before the age of 14. This observation expands the spectrum of benign epileptic phenotypes present in Fragile-X-syndrome and may be quite helpful in guiding anticonvulsant management and counseling families as to expectations regarding seizure remission. © 2017 Wiley Periodicals, Inc.

    2017-04-01

    Full Text Available Carcinoid tumors are neuroendocrine tumors that mainly arise in the gastrointestinal tract, lungs, and bronchi. Bronchopulmonary carcinoids have been associated with Cushing syndrome, which results from ectopic adrenocorticotrophic hormone (ACTH secretion. We report the case of a 65-year-old man, a colonel in the US Air Force, with metastatic bronchopulmonary carcinoid tumors treated on a clinical trial who was hospitalized for complaints of increasing thirst, polydipsia, polyuria, weakness, and visual changes. Decompensated hyperglycemia suggested a diagnosis of hyperglycemic hyperosmolar nonketotic syndrome (HHNS. Additional findings, which included hypokalemia, hypernatremia, hypertension, metabolic alkalosis, moon facies, and striae, raised a red flag for an ectopic ACTH syndrome. Elevated ACTH levels confirmed Cushing syndrome. Treatment with a fluid replacement and insulin drip resulted in immediate symptomatic improvement. Cushing syndrome should be considered in carcinoid patients with physical stigmata such as moon facies and striae. HHNS may be the presenting clinical feature in patients with impaired glucose metabolism.

  1. Lumbar dorsal ramus syndrome.

    Science.gov (United States)

    Bogduk, N

    1980-11-15

    Low back pain, referred pain in the lower limbs, and spasm of the back, gluteal, and hamstring muscles are clinical features which can be induced in normal volunteers by stimulating structures which are innervated by the lumbar dorsal rami. Conversely, they can be relieved in certain patients by selective interruption of conduction along dorsal rami. These facts permit the definition of a lumbar dorsal ramus syndrome, which can be distinguished from the intervertebral disc syndrome and other forms of low back pain. The distinguishing feature is that, in lumbar dorsal ramus syndrome, all the clinical features are exclusively mediated by dorsal rami and do not arise from nerve-root compression. The pathophysiology, pathology, and treatment of this syndrome are described. Recognition of this syndrome, and its treatment with relatively minor procedures, can obviate the need for major surgery which might otherwise be undertaken.

    Endogenous hypercortisolism (Cushing syndrome) is one of the most enigmatic diseases in clinical medicine. The diagnosis and differential diagnosis of Cushing syndrome depend on proper laboratory evaluation. In this review, an update is provided on selected critical issues in the diagnosis and differential diagnosis of Cushing syndrome: the use of late-night salivary cortisol in initial diagnosis and for postoperative surveillance, and the use of prolactin measurement to improve the performance of inferior petrosal sinus sampling to distinguish Cushing disease from ectopic adrenocorticotropic hormone (ACTH) syndrome during differential diagnosis of ACTH-dependent Cushing syndrome.

    A case report and literature review is presented. To review relevant data for the management of Bertolotti's syndrome and to determine whether the transverse process-ilium articulation may be a pain generator. Bertolotti's syndrome is associated with axial low back pain secondary to arthritic changes; the pain generator in the disorder is unclear. We present a case report of symptomatic Bertolotti's syndrome managed with intra-articular steroid injections. A patient with Bertolotti's syndrome had significant relief of axial pain after steroid injection of the ilium-transverse process articulation. Steroid therapy may be a non-surgical alternative for the treatment of symptomatic Bertolotti's syndrome.

    Taba Taba Vakili, Sahar; Alam, Tausif; Sollinger, Hans

    2014-09-01

    Loin pain hematuria syndrome is a rare disease with a prevalence of ∼0.012%. The most prominent clinical features include periods of severe intermittent or persistent unilateral or bilateral loin pain accompanied by either microscopic or gross hematuria. Patients with loin pain hematuria syndrome initially present with hematuria, flank pain, or most often both hematuria and flank pain. Kidney biopsies from patients with loin pain hematuria typically reveal only minor pathologic abnormalities. Further, loin pain hematuria syndrome is not associated with loss of kidney function or urinary tract infections. Loin pain hematuria syndrome-associated hematuria and pain are postulated to be linked to vascular disease of the kidney, coagulopathy, renal vasospasm with microinfarction, hypersensitivity, complement activation on arterioles, venocalyceal fistula, abnormal ureteral peristalsis, and intratubular deposition of calcium or uric acid microcrystals. Many patients with loin pain hematuria syndrome also meet criteria for a somatoform disorder, and analgesic medications, including narcotics, commonly are used to treat loin pain hematuria syndrome-associated pain. Interventional treatments include renal denervation, kidney autotransplantation, and nephrectomy; however, these methods should be used only as a last resort when less invasive measures have been tried unsuccessfully. In this review article, we discuss and critique current clinical practices related to loin pain hematuria syndrome pathophysiology, diagnosis, treatment, and prognosis.

    Fuat Torun

    2011-09-01

    Full Text Available Children who have been programmed by one parent to be alienated from the other parent are commonly seen in the context of child-custody disputes. Its primary manifestation is the child’s campaign of denigration against a parent, a campaign that has no justification. It is said to result from a combination of a programming (brainwashing parent’s indoctrinations and the child’s own contributions to the vilification of the targeted parent. Many evaluators use the term parental alienation syndrome to refer to the disorder engendered in such children. However, there is significant controversy going on about the validity of parental alienation syndrome. The purpose of this article has been to describe and help to differentiate parental alienation syndrome and abuse for mental health professionals working in the field, and discuss the arguments about the validity of this syndrome.

    2012-01-01

    Syndromic diarrhea (or trichohepatoenteric syndrome) is a rare congenital bowel disorder characterized by intractable diarrhea and woolly hair, and it has recently been associated with mutations in TTC37. Although databases report TTC37 as being the human ortholog of Ski3p, one of the yeast Ski-complex cofactors, this lead was not investigated in initial studies. The Ski complex is a multiprotein complex required for exosome-mediated RNA surveillance, including the regulation of normal mRNA and the decay of nonfunctional mRNA. Considering the fact that TTC37 is homologous to Ski3p, we explored a gene encoding another Ski-complex cofactor, SKIV2L, in six individuals presenting with typical syndromic diarrhea without variation in TTC37. We identified mutations in all six individuals. Our results show that mutations in genes encoding cofactors of the human Ski complex cause syndromic diarrhea, establishing a link between defects of the human exosome complex and a Mendelian disease.

    DOORS syndrome (Deafness, Onychodystrophy, Osteodystrophy, mental Retardation, Seizures) is characterized mainly by sensorineural deafness, shortened terminal phalanges with small nails of hands and feet, intellectual deficiency, and seizures. Half of the patients with all clinical features have mutations in TBC1D24. We review here the manifestations of patients clinically diagnosed with DOORS syndrome. In this cohort of 32 families (36 patients) we detected 13 individuals from 10 families with TBC1D24 mutations. Subsequent whole exome sequencing in the cohort showed the same de novoSMARCB1 mutation (c.1130G>A), known to cause Coffin-Siris syndrome, in two patients. Distinguishing features include retinal anomalies, Dandy-Walker malformation, scoliosis, rocker bottom feet, respiratory difficulties and absence of seizures, and 2-oxoglutaric aciduria in the patients with the SMARCB1 mutation. We briefly discuss the heterogeneity of the DOORS syndrome phenotype and the differential diagnosis of this condition. © 2014 Wiley Periodicals, Inc.

    Patients with nephrotic syndrome are at risk of developing thrombosis in both veins and arteries. Various manifestations in different organs have been reported. Thrombi in heart seen, associated with multi organ thrombosis have been reported on autopsy earlier, but only once in a living patient with nephrotic syndrome. Here, we report a 13 years old boy with steroid-resistant nephrotic syndrome, who developed an asymptomatic but potentially hazardous large intracardiac thrombus. The child developed nephrotic syndrome at the age of 9 years and had multiple recurrences. At the age of 13 years, he developed myocardial infarction (MI) due to embolism from a large intracardiac thrombus. Later on, he was treated with heparin and warfarin anticoagulation. (author)

    Goltz-Gorlin syndrome is a rare autosomal dominant hereditary disease associated with a high rate of spontaneous mutation. Diagnosis is based on clinically defined major and minor criteria. The disease is caused by a gene mutation locating to chromosome 9q22-31. We report on a young Goltz-Gorlin syndrome patient with obstructive sleep apnea syndrome. Due to intolerance to continuous positive airway pressure (CPAP) therapy and in order to avoid a tracheotomy, we opted for an alternative therapy comprising interdisciplinary multi-level surgery.

    It is not common for a patient who survives cardiac arrest to experience significant neurologic impairment such as acute and chronic post-hypoxic myoclonus, known as Lance-Adams syndrome. This syndrome is predominantly characterized by myoclonus that starts days to weeks after cardiopulmonary resuscitation in patients who regained consciousness. Although several cases of LAS were reported, the decisive treatment method has not been established. We report a 43 year old man with Lance-Adams syndrome who showed long-term improvement through treatment with anti-myoclonic agents and participation in a rehabilitation program.

    Full Text Available Wells’ syndrome (WS is an uncommon inflammatory skin disease which typically presents single or multiple erythematous and edematous urticarial plaques similar to cellulitis. The lesions may evolve into blue-grey morphea-like lesions and may persist for weeks or months. They ultimately heal without scar. Other clinical presentations reported in literature include papular and nodular and, rarely, bullous eruptions. Previously, bullous Wells’ syndrome was rarely reported in the literature. Herein, we describe a case of a female patient with bullous Wells’ syndrome localized to the upper limbs without any associated disorders.

    Caregiver syndrome may develop in caregivers of elderly adults. To evaluate the repercussions of the immobility syndrome present in elderly adults on their primary caregivers as well as to determine the clinical and socio-demographic characteristics of the elderly adult and caregiver. The study population included patients over 65 recruited in the Geriatric Rehabilitation Department, with the diagnosis of immobility syndrome and that required a primary caregiver. A questionnaire including socio-demographic variables was applied to all patients and caregivers, and the Zarit scale was also applied to caregivers in order to determine the presence of caregiver syndrome. Analysis was performed with descriptive statistical methods; Student's t test and Fisher's test were used for comparisons between strata. 75 patients and their caregivers were evaluated; patient average age was 75.9 years and 85.3% were female. 50.7% (38 cases) had mild immobility. The average caregiver's age was 50.6%, 70.7% were female and 57.3% were the patient's daughter. Caregiver syndrome was detected in 60% of them: 57.7% had mild symptoms and in 42.2%, symptoms were moderate to severe. No statistically significant association was established between the development of caregiver syndrome and the degree of patient immobility. Caregivers of patients with immobility syndrome are at high risk of developing caregiver syndrome, thus underscoring the need to include primary caregiver support programs.

    Full Text Available Abstract Introduction To the best of our knowledge, this is the first report of a comorbidity between Gilles de la Tourette's syndrome and 47 (XXX syndrome. The clinical picture of Gilles de la Tourette's Syndrome is well described, while 47 (XXX syndrome is much more rare and has a broader spectrum of possible phenotypic presentations. Case presentation An Italian Caucasian girl was referred at the age of 11 to our Rehabilitation Center for anxiety and learning difficulties. The girl had already been diagnosed as having 47(XXX syndrome; she had some rather typical features of the chromosomal abnormality, but she also showed a high level of anxiety and the presence of motor and vocal tics. When an accurate history was taken, a diagnosis of Gilles de la Tourette's Syndrome emerged. Conclusions The possible interaction between peculiar features of these two syndromes in terms of neuropsychological and affective functioning is both interesting for the specific case and to hypothesize models of rehabilitation for patients with one or both syndromes. Executive functions are specifically reduced in both syndromes, therefore it might be hard to discriminate the contribution of each one to the general impairment; the same applies to anxiety. Moreover, mental retardation (with a significantly lower verbal cognitive functioning poses relevant problems when suggesting cognitive behavioral or psychoeducational rehabilitative approaches.

  11. Polycystic ovary syndrome: a common reproductive syndrome with long-term metabolic consequences.

    Polycystic ovary syndrome is the most common endocrine disorder among women of reproductive age. Although traditionally viewed as a reproductive disorder, there is increasing appreciation that it is associated with significantly increased risk of cardiometabolic disorders. Women with polycystic ovary syndrome may present to clinicians via a variety of different routes and symptoms. Although the impact on reproduction predominates during the reproductive years, the increased cardiometabolic problems are likely to become more important at later stages of the life course. Women with polycystic ovary syndrome have an approximately 2- to 5-fold increased risk of dysglycaemia or type 2 diabetes, and hence regular screening with oral glucose tolerance test is warranted. Although the diagnostic criteria for polycystic ovary syndrome are still evolving and are undergoing revision, the diagnosis is increasingly focused on the presence of hyperandrogenism, with the significance of polycystic ovarian morphology in the absence of associated hyperandrogenism or anovulation remaining uncertain. The management of women with polycystic ovary syndrome should focus on the specific needs of the individual, and may change according to different stages of the life course. In view of the clinical manifestations of the condition, there is recent debate about whether the current name is misleading, and whether the condition should be renamed as metabolic reproductive syndrome.

    Mitochondrial DNA depletion syndrome 5 (MIM 612073) is a rare autosomal recessive disorder caused by homozygous or compound heterozygous pathogenic variants in the beta subunit of the succinate-CoA ligase gene located within the 13q14 band. We describe two siblings of Hispanic descent with SUCLA2-related mitochondrial depletion syndrome (encephalomyopathic form with methylmalonic aciduria); the older sibling is additionally affected with trisomy 21. SUCLA2 sequencing identified homozygous p.Arg284Cys pathogenic variants in both patients. This mutation has previously been identified in four individuals of Italian and Caucasian descent. The older sibling with concomitant disease has a more severe phenotype than what is typically described in patients with either SUCLA2-related mitochondrial depletion syndrome or Down syndrome alone. The younger sibling, who has a normal female chromosome complement, is significantly less affected compared to her brother. While the clinical and molecular findings have been reported in about 50 patients affected with a deficiency of succinate-CoA ligase caused by pathogenic variants in SUCLA2, this report describes the first known individual affected with both a mitochondrial depletion syndrome and trisomy 21. © 2017 Wiley Periodicals, Inc.

  19. Nakalanga Syndrome: Clinical Characteristics, Potential Causes, and Its Relationship with Recently Described Nodding Syndrome.

    2017-02-01

    Full Text Available Nakalanga syndrome is a condition that was described in Uganda and various other African countries decades ago. Its features include growth retardation, physical deformities, endocrine dysfunction, mental impairment, and epilepsy, amongst others. Its cause remains obscure. Nodding syndrome is a neurological disorder with some features in common with Nakalanga syndrome, which has been described mainly in Uganda, South Sudan, and Tanzania. It has been considered an encephalopathy affecting children who, besides head nodding attacks, can also present with stunted growth, delayed puberty, and mental impairment, amongst other symptoms. Despite active research over the last years on the pathogenesis of Nodding syndrome, to date, no convincing single cause of Nodding syndrome has been reported. In this review, by means of a thorough literature search, we compare features of both disorders. We conclude that Nakalanga and Nodding syndromes are closely related and may represent the same condition. Our findings may provide new directions in research on the cause underlying this neurological disorder.

    2012-01-01

    Full Text Available Background: Wolfram syndrome is a rare hereditary or sporadic neurodegenerative disorder also known as DIDMOAD. The classically described presentation is of insulin-dependent diabetes, followed by optic atrophy, central diabetes insipidus, and sensory neural deafness. Also included are less well-described presentations of Wolframs syndrome. We here present three cases of atypical presentation of this syndrome. Case 1: A 15-year-old boy with insulin-dependent diabetes was presented for evaluation of depressive symptoms associated with suicidal tendency. Neuropsychiatric manifestations are described with Wolframs syndrome, and wolframin gene, in recessive inheritance, is associated with psychiatric illnesses without other manifestations of Wolframs syndrome. Case 2: A 17-year-old diabetic boy on insulin with good control of blood sugar presented for evaluation of delayed puberty. Central hypogonadism and other anterior pituitary hormone dysfunctions are the less publicized hormone dysfunctions in Wolframs syndrome. Case 3: A 23-year-old female who was on insulin for diabetes for the past 14 years, got admitted for evaluation of sudden loss of vision. This patient had developed a vitreous hemorrhage and, on evaluation, was found to have optic atrophy, sensory neural hearing loss, and diabetes insipidus, and presented differently from the gradual loss of vision described in Wolframs syndrome. Conclusion: Wolframs syndrome being a multisystem degenerative disorder can have myriad other manifestations than the classically described features. Neuropsychiatric manifestations, depression with suicidal risk, central hypogonadism, and secondary adrenal insufficiency are among the less well-described manifestations of this syndrome.

    2018-04-01

    The life-threatening drug rash with eosinophilia and systemic symptoms (DRESS) syndrome occurs most commonly after exposure to drugs, clinical features mimic those found with other serious systemic disorders. It is rarely associated with thrombotic microangiopathy. We describe the unique case of a 44-year-old man who simultaneously experienced DRESS syndrome with thrombotic microangiopathy (TMA) after a 5 days treatment with fluindione. Clinical evaluation leads to the discovery of an underlying lymphangiomatosis, due to a Noonan syndrome. The anticoagulant was withdrawn, and corticosteroids (1 mg/kg/day) and acenocoumarol were started. Clinical improvement ensued. At follow-up the patient is well. The association of DRESS with TMA is a rare condition; we believe that the presence of the underlying Noonan syndrome could have been the trigger. Moreover, we speculate about the potential interrelations between these entities.

  2. Lynch Syndrome: An Updated Review

    Full Text Available Lynch syndrome is one of the most common cancer susceptibility syndromes. Individuals with Lynch syndrome have a 50%–70% lifetime risk of colorectal cancer, 40%–60% risk of endometrial cancer, and increased risks of several other malignancies. It is caused by germline mutations in the DNA mismatch repair genes MLH1, MSH2, MSH6 or PMS2. In a subset of patients, Lynch syndrome is caused by 3' end deletions of the EPCAM gene, which can lead to epigenetic silencing of the closely linked MSH2. Relying solely on age and family history based criteria inaccurately identifies eligibility for Lynch syndrome screening or testing in 25%–70% of cases. There has been a steady increase in Lynch syndrome tumor screening programs since 2000 and institutions are rapidly adopting a universal screening approach to identify the patients that would benefit from genetic counseling and germline testing. These include microsatellite instability testing and/or immunohistochemical testing to identify tumor mismatch repair deficiencies. However, universal screening is not standard across institutions. Furthermore, variation exists regarding the optimum method for tracking and disclosing results. In this review, we summarize traditional screening criteria for Lynch syndrome, and discuss universal screening methods. International guidelines are necessary to standardize Lynch syndrome high-risk clinics.

    The aim of this study was to evaluate audiologic properties of patients with Noonan syndrome and compare these findings with those of unaffected peers. The study included 17 children with Noonan syndrome and 20 typically developing children without Noonan syndrome. Pure tone and speech audiometry, immitancemetric measurement, otoacoustic emissions measurement and auditory brainstem response tests were applied to all (n = 37) children. Hearing thresholds of children with Noonan syndrome were higher (poorer) than those observed unaffected peers, while the hearing sensitivity of the both groups were normal limits (p = 0.013 for right, p = 0.031 for left ear). Transient evoked otoacoustic emissions amplitudes of the children with Noonan syndrome were lower than the children without Noonan syndrome (p = 0.005 for right, p = 0.002 for left ear). Middle ear pressures and auditory brainstem response values were within normal limits and there was no difference between the two groups (p > 0.05). General benefit of the present study is to characterize the audiologic findings of children with Noonan syndrome, which is beneficial in clinics evaluating children with Noonan syndrome.

    Cushing's syndrome is a rare condition in the general population and is even less common during pregnancy with only a few cases reported in literature. The diagnosis of Cushing's syndrome may be difficult during pregnancy because the typical features of the disorder and pregnancy may overlap. However, Cushing's syndrome results in increased fetal and maternal complications, and diagnosis and treatment are critical. This report describes a case of 26-year-old female at the 19th week of pregnancy with symptoms and signs of hypercortisolism, where ACTH-independent Cushing's syndrome was diagnosed and treated by robotic laparoscopic adrenalectomy at the 21th week of gestation.

    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.

    This report presents a case of a 71-year-old woman with Fisher syndrome who had posterior reversible encephalopathy syndrome (PRES) before the initiation of intravenous immunoglobulin (IVIg) treatment. She had symptoms of common cold 2 weeks before the onset of PRES. On the day of the onset, she began to stagger while walking. On day 2, she developed hypertension, vision impairment, and limb weakness and was admitted to the hospital. On day 3, she was provided steroid pulse therapy. On day 4, she developed convulsions and right imperfection single paralysis and was transferred to the our hospital. During the transfer, the patient was conscious. Her blood pressure was high at 198/107 mmHg. She had mild weakness in her limbs and face, light perception in both eyes, dilation of both pupils, total external ophthalmoplegia, no tendon reflexes, and limb and trunk ataxia. We diagnosed PRES because of the high signal intensities observed on T 2 -weighted MRI on both sides of the parietal and occipital lobes. We also diagnosed Fisher syndrome because of a positive anti-GQ1b immunoglobulin G antibody test and albuminocytologic dissociation in the cerebrospinal fluid. PRES showed prompt improvement with antihypertensive therapy, whereas Fisher syndrome slowly improved over a course of 2 months. This case is the first report of PRES without IVIg suggesting that Fisher syndrome induces hypertension and causes PRES.

    To study the correlation between Chinese medical types of coronary heart disease (CHD) [i.e., phlegm turbidity syndrome (PTS) and qi deficiency syndrome (QDS)] and their metabolites. Recruited were 65 CHD patients including 37 cases of PTS and 28 cases of QDS. Serum endogenous metabolites in the two syndrome types were determined by gas chromatograph-mass spectrometer-computer (GC/MS), and their differences between their metabolic profiles analyzed. More than 100 chromatographic peaks were totally scanned. Chromatograms obtained was matched with mass spectrum bank, and finally we got the category contribution value of 46 kinds of substances. Results of MCTree analysis showed patients of PTS and patients of QDS could be effectively distinguished. Compounds contributing to identify the two syndromes were sequenced as serine, valine, 2 hydroxy propionic acid. Comparison of metabolites showed contents of serine and 2 hydroxy propionic acid were higher in patients of PTS than in patients of QDS (Pmetabonomics of CHD TCM syndrome types could provide material bases for TCM syndrome differentiation of CHD, indicating that metabonomics technologies might become a new research method for TCM syndrome typing.

  18. Ehlers-Danlos syndrome(s) mimicking child abuse: Is there an impact on clinical practice?

    Science.gov (United States)

    Castori, Marco

    2015-12-01

    Ehlers-Danlos syndrome is a heterogeneous group of heritable connective tissue disorders characterized by increased fragility of various non-ossified tissues. It is usually ascertained due to abnormal skin texture, scarring complications, vascular fragility, or chronic symptoms, such as fatigue and musculoskeletal pain. Sometimes, Ehlers-Danlos syndrome remains undetected until the patient, usually in the pediatric age, shows extensive or severe mucocutaneous injuries after only minor traumas. In this scenario, the misdiagnosis of Ehlers-Danlos syndrome with child abuse is a possibility, as occasionally reported in the literature. Recently, more attention was posed by lay people between the possible association of Ehlers-Danlos syndrome and bone fragility. Literature and personal experience show a strong association between Ehlers-Danlos syndrome, generalized joint hypermobility and reduced bone mass density in older children and adults, especially fertile women. The existence of a true increased risk of fracture in Ehlers-Danlos syndrome is still a matter of debate in children and adults with little and conflicting evidence. In case of suspected child abuse, Ehlers-Danlos syndrome is certainly on the differential for bruising, especially in EDS types with marked cutaneous and capillary involvement. In suspected child abuse cases, careful examination of the index case and her/his extended family is routine, as well as exclusion of other disorders such as osteogenesis imperfecta. The hypothesis of Ehlers-Danlos syndrome as an alternative explanation for infantile fractures remains speculative. © 2015 Wiley Periodicals, Inc.

    Unusual headache syndromes are not as infrequent in clinical practice as was generally believed. About three fourths of the classified headache disorders found in the ICHD-II can be considered rare. The aim of this narrative review was to perform a literature review of the pathophysiology, clinical presentation, diagnostic criteria, and treatment of the following unusual headache disorders: Alice in Wonderland syndrome, burning mouth syndrome, cold stimulus headache, and the syndrome of transient headache and neurologic deficits with cerebrospinal fluid lymphocytosis. A literature review was performed using PubMed for each of the abovementioned headache disorders. The unusual headache syndromes as a distinct group of disorders are not as infrequent in clinical practice as was generally believed. Some of them, albeit considered as unusual, may occur with relative frequency, such as cold stimulus headache and burning mouth syndrome. © 2015 American Headache Society.

    The Gorlin-Goltz syndrome (GGS) (the nevoid basal cell carcinoma syndrome-NBCCS) is an autosomal dominant syndrome caused by mutations found on chromosome 9. The syndrome is characterized by increased predisposition to develop a basal cell carcinoma and associated with multiorgan anomalies. To present a case of GGS and explain modern standards of care for patients with this syndrome. Authors report the case of a 36-year-old patient who was admitted to the Plastic Surgery Clinic due to numerous basal cell carcinomas. Previously patient underwent an orthopaedic, neurologic, dermatologic, stomatologic and surgery treatment due to particular anomalies which characterize this syndrome. Comprehensive interview and broadening of the diagnostics enabled to diagnose GGS and to introduce the appropriate treatment. GGS is a multidisciplinary problem and widespread knowledge of this syndrome could accelerate the diagnosis process. Early diagnosis of GGS allows to introduce the secondary prophylaxis and to apply the appropriate treatment to slow the progress of the syndrome.

    Many different heritable connective tissue disorders (HCTD) have been described over the past decades. These syndromes often affect the connective tissue of various organ systems, including heart, blood vessels, skin, joints, bone, eyes, and lungs. The discovery of these HCTD was followed by the identification of mutations in a wide range of genes encoding structural proteins, modifying enzymes, or components of the TGFβ-signaling pathway. Three typical examples of HCTD are Marfan syndrome (MFS), Ehlers-Danlos syndrome (EDS), and Loeys-Dietz syndrome (LDS). These syndromes show some degree of phenotypical overlap of cardiovascular, skeletal, and cutaneous features. MFS is typically characterized by cardiovascular, ocular, and skeletal manifestations and is caused by heterozygous mutations in FBN1 , coding for the extracellular matrix (ECM) protein fibrillin-1. The most common cardiovascular phenotype involves aortic aneurysm and dissection at the sinuses of Valsalva. LDS is caused by mutations in TGBR1/2 , SMAD2/3 , or TGFB2/3 , all coding for components of the TGFβ-signaling pathway. LDS can be distinguished from MFS by the unique presence of hypertelorism, bifid uvula or cleft palate, and widespread aortic and arterial aneurysm and tortuosity. Compared to MFS, LDS cardiovascular manifestations tend to be more severe. In contrast, no association is reported between LDS and the presence of ectopia lentis, a key distinguishing feature of MFS. Overlapping features between MFS and LDS include scoliosis, pes planus, anterior chest deformity, spontaneous pneumothorax, and dural ectasia. EDS refers to a group of clinically and genetically heterogeneous connective tissue disorders and all subtypes are characterized by variable abnormalities of skin, ligaments and joints, blood vessels, and internal organs. Typical presenting features include joint hypermobility, skin hyperextensibility, and tissue fragility. Up to one quarter of the EDS patients show aortic aneurysmal

    A 76-year-old woman suddenly developed anasarca and a fever, and an examination revealed thrombocytopenia, reticulin fibrosis, and acute kidney injury, yielding the diagnosis of TAFRO syndrome. Renal replacement therapy and steroid treatment were soon started. Her proteinuria was minor at first; however, once the kidney function improved, nephrotic syndrome occurred. A kidney biopsy showed membranoproliferative glomerulonephritis-like glomerulopathy with massive macrophage infiltration. Although kidney dysfunction is often observed in TAFRO syndrome patients, its detailed mechanism is unclear. This case suggests that TAFRO syndrome involves both acute kidney injury with minor proteinuria and nephrotic syndrome, and these disorders can develop serially in the same patient.

    Williams-Beuren syndrome is a rare familial multisystem disorder occurring in 1 per 20,000 live births. It is characterized by congenital heart defects (CHD), skeletal and renal anomalies, cognitive disorder, social personality disorder and dysmorphic facies. We present a case of Williams syndrome that presented to us with heart murmur and cognitive problem. A 5-year-old girl referred to pediatric cardiologist because of heart murmurs. She had a systolic murmur (2-3/6) in right upper sternal border with radiation to right cervical region. She also had a bulge forehead. Angiography showed mild supra valvular aortic stenosis and mild multiple peripheral pulmonary stenosis. Fluorescent in situ hybridization (FISH) was performed and the result was: 46.XX, ish del (7q11.2) (ELN X1) (7q22 X2) ELN deletion compatible with Williams syndrome. Peripheral pulmonary artery stenosis is associated with Noonan syndrome, Alagille syndrome, Cutis laxa, Ehler-Danlos syndrome, and Silver-Russel syndrome. The patient had peripheral pulmonary artery stenosis, but no other signs of these syndromes were present, and also she had a supravalvular aortic stenosis which was not seen in other syndromes except Williams syndrome. Conclusion. According to primary symptoms, paraclinical and clinical finding such as dysmorphic facies, cognitive disorder and congenital heart defect, Williams syndrome was the first diagnosis. We suggest a more attention for evaluating heart murmur in childhood period, especially when the patient has abnormal facial features or mental problem.

    We report a man and his two daughters (one stillborn) with an apparently unique constellation of anomalies including fifth finger/toe terminal phalanx and nail hypoplasia. The craniofacial manifestations include large boxy head, round face, hypertelorism with downslanting palpebral fissures and wide mouth. Other manifestations include brachydactyly, fifth finger clinodactyly and ventricular septal defect. Intelligence is normal. The resemblance to Coffin-Siris, Brachymorphism-Onychodysplasia-Dysphalangism and DOOR syndromes is discussed and we concluded that this family probably represents a new autosomal dominant syndrome.

    Full Text Available Management of anaphylaxis includes adrenaline, a life-saving drug, however appropriate dosing and administration are of crucial importance due to serious side effects. We present a 15-year-old female with anaphylactic reaction manifesting as acute coronary syndrome and pulmonary edema following the administration of adrenaline as an intravenous bolus. Focusing on anaphylaxis, adrenaline and coronary symptoms, this report discussed the interactions between three intertwining entities: Kounis syndrome, Takotsubo cardiomyopathy, and adrenaline-induced coronary vasospasm, and challenges in differential diagnosis. Brugada syndrome (cardiac autonomic dysfunction and clinical manifestation of the patient was also evaluated. Early consideration of adrenaline at the appropriate dose and administration route is essential in anaphylaxis management. Kounis syndrome should be considered in those presenting with allergy symptoms and chest pain and adrenaline should be used carefully due to possible risks of worsening coronary symptoms in patients with Kounis syndrome. This report also highlights a very rare side effect of adrenaline; the drug, which constitutes the cornerstone of anaphylaxis management, has a potential to trigger allergy itself due to metabisulfite-containing preservative.

    It is the purpose of the study to demonstrate the clinical relevance of degenerative changes in the facet joint of patients with low back pain irradiating to the lower extremities, and discuss some problems relating to diagnosis and different diagnosis. 119 patients presenting the listed bellow syndromes are covered by the study: scoliosis, polytopic pain vertebral syndrome, paresis and history of trauma. all patients undergo comprehensive neurological examination with special attention focused on the spine: CT and plain x-rays are taken of the lumbosacral segment to assess the condition of the facet joints. The neurological examination demonstrates in all cases pain syndrome in the lumbar spine referred to one or both lower extremities. In 56% it is a matter of persisting pain, and in 44% - recurrent. More than half of the patients complain of sacroiliac (SI) dislocation and palpatory pain. Unilateral or bilateral degenerative changes are documented by imaging studies in all patients, including: subchondral thickening, osteopathy narrowing the lateral or central part of the spinal canal with ensuing nerve root compression. The lumbosacral zygoapophyseal joints are source of pseudoradicular pain. A correlation between clinical picture and GT changes is noted in all patients with facet joint syndrome. CT is an indispensable method in diagnosing facet joint syndrome. (authors)

    Full Text Available Metabolic syndrome represents a sum of risk factors that lead to the occurrence of cardiovascular and cerebrovascular events. The early detection of metabolic syndrome is extremely important in adults who are at risk. Although the physiopathological mechanisms of the metabolic syndrome are not yet clear, insulin resistance plays a key role that could explain the development of type 2 diabetes mellitus in untreated metabolic syndrome patients. Here, we present the case of a 26-year-old male who was diagnosed with metabolic syndrome and severe hypertriglyceridemia after presenting with abdominal pain. Although hypertriglyceridemia and hyperglycemia are the most common predictors of metabolic syndrome, clinicians need to be vigilant for unexpected presentations in patients at risk for metabolic syndrome. This case sheds light on the importance of early detection.

  17. Calcineurin-inhibitor pain syndrome.

    Science.gov (United States)

    Prommer, Eric

    2012-07-01

    There has been increased recognition of calcineurin, a phosphoprotein serine/threonine phosphatase enzyme, in the regulation of many physiologic systems. Calcineurin mediates activation of lymphocytes, which play a role in immune response. Widely distributed in the central nervous system, calcinuerin also plays an important role in sensory neural function, via its role in the regulation of newly discovered 2-pore potassium channels, which greatly influence neuronal resting membrane potentials. Calcinuerin inhibition is the mechanism of action of immunomodulatory drugs such as cyclosporine and tacrolimus, which are widely used in transplantation medicine to prevent rejection. While important for immunosuppression, the use of calcineurin inhibitors has been associated with the development of a new pain syndrome called the calcineurin pain syndrome, which appears to be an untoward complication of the interruption of the physiologic function of calcineurin. This is a narrative review focusing on the epidemiology, pathophysiology, characterization of a newly recognized pain syndrome associated with the use of calcineurin inhibitors. The use of immunosuppressants however is associated with several well-known toxicities to which the calcineurin pain syndrome can be added. The development of this syndrome most likely involves altered nociceptive processing due to the effect of calcineurin inhibition on neuronal firing, as well as effects of calcineurin on vascular tone. The most striking aspect of the treatment of this syndrome is the response to calcium channel blockers, which suggest that the effects of calcineurin inhibition on vascular tone play an important role in the development of the calcineurin pain syndrome. The calcineurin syndrome is a newly recognized complication associated with the use of calcineurin inhibitors. There is no standard therapy at this time but anecdotal reports suggest the effectiveness of calcium channel blockers.

    Full Text Available OBJECTIVE: this study aimed to investigate the cognitive and behavioral profiles, as well as the psychiatric symptoms and disorders in children with three different genetic syndromes with similar sociocultural and socioeconomic backgrounds. METHODS: thirty-four children aged 6 to 16 years, with Williams-Beuren syndrome (n = 10, Prader-Willi syndrome (n = 11, and Fragile X syndrome (n = 13 from the outpatient clinics of Child Psychiatry and Medical Genetics Department were cognitively assessed through the Wechsler Intelligence Scale for Children (WISC-III. Afterwards, a full-scale intelligence quotient (IQ, verbal IQ, performance IQ, standard subtest scores, as well as frequency of psychiatric symptoms and disorders were compared among the three syndromes. RESULTS: significant differences were found among the syndromes concerning verbal IQ and verbal and performance subtests. Post-hoc analysis demonstrated that vocabulary and comprehension subtest scores were significantly higher in Williams-Beuren syndrome in comparison with Prader-Willi and Fragile X syndromes, and block design and object assembly scores were significantly higher in Prader-Willi syndrome compared with Williams-Beuren and Fragile X syndromes. Additionally, there were significant differences between the syndromes concerning behavioral features and psychiatric symptoms. The Prader-Willi syndrome group presented a higher frequency of hyperphagia and self-injurious behaviors. The Fragile X syndrome group showed a higher frequency of social interaction deficits; such difference nearly reached statistical significance. CONCLUSION: the three genetic syndromes exhibited distinctive cognitive, behavioral, and psychiatric patterns.

    Full Text Available Gorlin-Goltz syndrome is an uncommon autosomal dominant inherited disorder, which is characterized by multiple odontogenic Keratocysts and basal cell carcinomas, skeletal, dental, ophthalmic, and neurological abnormalities, intracranial ectopic calcifications of the falx cerebri, and facial dysmorphism. Pathogenesis of the syndrome is attributed to abnormalities in the long arm of chromosome 9 (q22.3-q31 and loss or mutations of human patched gene (PTCH1 gene. Diagnosis is based upon established major and minor clinical and radiological criteria and ideally confirmed by deoxyribo nucleic acid analysis. We report a case of a 9-year-old girl presenting with three major and one minor feature of Gorlin-Goltz syndrome. Radiologic findings of the syndrome are easily identifiable on Orthopantomogram, chest X-ray, and Computed tomography scans. These investigations prompt an early verification of the disease, which is very important to prevent recurrence and better survival rates from the coexistent diseases.

    Exploding head syndrome is characterized by the perception of abrupt, loud noises when going to sleep or waking up. They are usually painless, but associated with fear and distress. In spite of the fact that its characteristic symptomatology was first described approximately 150 y ago, exploding head syndrome has received relatively little empirical and clinical attention. Therefore, a comprehensive review of the scientific literature using Medline, PsycINFO, Google Scholar, and PubMed was undertaken. After first discussing the history, prevalence, and associated features, the available polysomnography data and five main etiological theories for exploding head syndrome are summarized. None of these theories has yet reached dominance in the field. Next, the various methods used to assess and treat exploding head syndrome are discussed, as well as the limited outcome data. Finally, recommendations for future measure construction, treatment options, and differential diagnosis are provided. Copyright © 2014 Elsevier Ltd. All rights reserved.

    The authors present divergent opinions on the pathogenesis of vibratory syndrome, and primarily on its angio-neurological form, i.e. vascular, neurogenic and immunological theory. In the light of these concepts the clinical manifestations of vibratory syndrome are discussed in view of both systemic and local developments. The issues concerning neurological diagnostics with reference to the usefulness of electrophysiological methods are thoroughly analysed. Difficulties in early diagnosis and identification of symptoms that distinguish vibratory syndrome from other syndromes with similar manifestations are highlighted.

    Mazabraud syndrome is a very rare benign disorder characterized by the association of monostotic or polyostotic fibrous dysplasia and one or multiple intramuscular myxomas. McCune -Albright syndrome is a rare benign disorder characterized by the association of polyostotic fibrous dysplasia, cafè-au-lait skin pigmentations and endocrine dysfunction, such as precocious puberty, diabetes mellitus, goiter and breast fibroadenomatosis. The association of Mazabraud syndrome and McCune-Albright in the same patient is an anecdotal event. We report the case of a 28-year-old girl with Mazabraud syndrome associated with McCune-Albright syndrome. Our literature review shows that in these patients there is a higher risk of malignant transformation of fibrous dysplasia into osteosarcoma, confirming previous reports. Conversely, no malignant transformation has been reported for myxomas in isolated Mazabraud syndrome or in the association with McCune-Albright syndrome. We conclude that these patients should be scheduled to a close and long-term follow-up.

    Polycystic ovary syndrome is a heterogeneous disorder and its presentation varies with race and ethnicity. Reproductive-age women with polycystic ovary syndrome are at increased risk of metabolic syndrome; however, it is not clear if prevalence of metabolic syndrome and clustering of its components differs based on race and ethnicity. Moreover, the majority of these women do not undergo routine screening for metabolic syndrome. We sought to compare the prevalence of metabolic syndrome and clustering of its components in women with polycystic ovary syndrome in the United States with women in India, Brazil, Finland, and Norway. This is a cross-sectional study performed in 1089 women with polycystic ovary syndrome from 1999 through 2016 in 5 outpatient clinics in the United States, India, Brazil, Finland, and Norway. Polycystic ovary syndrome was defined by the Rotterdam criteria. Main outcome measures were: metabolic syndrome prevalence, blood pressure, body mass index, fasting high-density lipoprotein cholesterol, fasting triglycerides, and fasting glucose. Data from all sites were reevaluated for appropriate application of diagnostic criteria for polycystic ovary syndrome, identification of polycystic ovary syndrome phenotype, and complete metabolic workup. The US White women with polycystic ovary syndrome were used as the referent group. Logistic regression models were used to evaluate associations between race and metabolic syndrome prevalence and its components and to adjust for potential confounders, including age and body mass index. The median age of the entire cohort was 28 years. Women from India had the highest mean Ferriman-Gallwey score for clinical hyperandrogenism (15.6 ± 6.5, P metabolic syndrome was highest in US Black women at 4.52 (95% confidence interval, 2.46-8.35) compared with US White women. When adjusted for age and body mass index, the prevalence was similar in the 2 groups. Significantly more Black women met body mass index and blood

    PAPA syndrome is a recently identified hereditary autoinflammatory syndrome clinically characterized by pyogenic arthritis, severe acne, and pyoderma gangrenosum. It is caused by mutations in the PSTPIP1 gene and may be closely linked to the aseptic abscesses syndrome, which has been shown to be associated with CCTG repeat amplification in the promoter region of PSTPIP1. We describe two unrelated patients with a clinical presentation quite similar to, yet distinct from, PAPA syndrome. Both patients had pyoderma gangrenosum and acute or remittent acne conglobata, but, in contrast to PAPA syndrome, lacked any episodes of pyogenic arthritis. Instead, they had suppurative hidradenitis. Mutations in PSTPIP1 exons 1 to 15 were excluded. In the promoter region, an increased repetition of the CCTG microsatellite motif was present on one allele in both patients. Alterations of the most commonly affected exons of the MEFV, NLRP3, and TNFRSF1A genes also were not detectable. One patient was treated with the interleukin (IL)-1 receptor antagonist anakinra and responded well, although without complete remission. This implies that IL-1ß may be of pathogenetic importance. Small number of patients, no gene mutation identified, and unclear efficacy of therapy are limitations. The clinical triad of pyoderma gangrenosum, acne, and suppurative hidradenitis represents a new disease entity within the spectrum of autoinflammatory syndromes, similar to PAPA and aseptic abscesses syndrome. For this disease, we propose the acronym "PASH" syndrome. PASH syndrome may respond to IL-1ß blockade. Copyright © 2011 American Academy of Dermatology, Inc. Published by Mosby, Inc.

    Objective: To determine the frequency of metabolic syndrome and its components in patients with carpal tunnel syndrome. Study Design: Case-series. Place and Duration of Study: Department of Neurology, Mayo Hospital, Lahore, from January to June 2012. Methodology: Seventy-five (64 females and 11 males) patients with clinically diagnosed and electrodiagnostically confirmed carpal tunnel syndrome were inducted. Their waist circumference, blood pressure, fasting blood glucose, fasting triglycerides and high density lipoprotein cholesterol levels were recorded. Patients were categorized having metabolic syndrome according to Adult Treatment Panel III criteria, if any 3 were present out of hypertension, elevated fasting triglycerides, reduced high density lipoprotein cholesterol, elevated fasting blood glucose, and elevated waist circumference. Result: Mean age of the patients was 42.04±9.31 years, mean waist circumference was 95.32±9.03 cm, mean systolic blood pressure was 134.13±13.72 mmHg, mean diastolic blood pressure was 89.13±8.83 mmHg, mean fasting blood glucose was 94.35±21.81 mg/dl, mean fasting triglycerides was 177.48±48.69 mg/dl, and mean high density lipoprotein cholesterol was 41.95±11.17 mg/dl. Metabolic syndrome was found in 54 (72 percentage) patients including 9 (16.7 percentage) males and 45 (83.3 percentage) females. Out of 75 patients, 54 (72 percentage) had elevated waist circumference, 52 (69.3 percentage) had elevated blood pressure, 19 (25.3 percentage) had elevated fasting blood glucose, 53 (70.6 percentage) had elevated fasting triglycerides and 54 (72 percentage) had reduced high density lipoprotein cholesterol. Highest frequency of metabolic syndrome was found in age range of 40 - 49 years in both genders. Conclusion: Metabolic syndrome is frequently found in the patients with carpal tunnel syndrome.

    To summarize the recent developments in endocrine disorders associated with Down syndrome. Current research regarding bone health and Down syndrome continues to show an increased prevalence of low bone mass and highlights the importance of considering short stature when interpreting dual energy x-ray absorptiometry. The underlying cause of low bone density is an area of active research and will shape treatment and preventive measures. Risk of thyroid disease is present throughout the life course in individuals with Down syndrome. New approaches and understanding of the pathophysiology and management of subclinical hypothyroidism continue to be explored. Individuals with Down syndrome are also at risk for other autoimmune conditions, with recent research revealing the role of the increased expression of the Autoimmune Regulatory gene on 21st chromosome. Lastly, Down-syndrome-specific growth charts were recently published and provide a better assessment of growth. Recent research confirms and expands on the previously known endocrinopathies in Down syndrome and provides more insight into potential underlying mechanisms.

    burnout syndrome is a state of physical and emotional exhaustion that can occur among workers who interact directly with others. This could affect job performance. The objective was to determine the prevalence of this syndrome and its associated factors among family physicians. a cross-sectional survey applying the Maslach Burnout Inventory was conducted in a selected convenience non-probability sampling of family physicians. Central tendency and dispersion measures were used in determining the prevalence of burnout syndrome; the associated factors were analysed by χ(2) test. there were 59 cases of burnout syndrome, 36 had involvement in a single component, 15 in 2 and 8 were affected in 3 components; we observed that 35 % of positive cases reported doing an average of 10 extra shifts a month (p = 0.013). Having a second job was associated with positive cases of burnout syndrome. the results are consistent with similar studies. Working extra shifts or having a second job were the related factors most associated to this syndrome.

    To evaluate burnout syndrome in its three aspects, jointly as well as independently, in physiotherapists from the Extremadura region (Spain). Analytic descriptive epidemiological transversal trial in primary care and institutional practice, with physiotherapists practicing in Extremadura who met the inclusion criteria, after having signed an informed consent form. Emotional exhaustion, depersonalization and low professional accomplishment were the outcomes measured. Physiotherapists from Extremadura show a 65.23 point level of burnout syndrome, according to the Maslach Burnout Inventory questionnaire. Therefore, they are positioned in the middle of the rating scale for the syndrome, and very near to the high level at starting score of 66 points. Physiotherapists in Extremadura present moderate scores for the three dimensions of burnout syndrome, namely, emotional exhaustion, depersonalization and low professional accomplishment. For this reason, they are in the moderate level of the syndrome and very near to the high level, which starts at a score of 66 points. No relation between burnout syndrome and age has been found in our study.

    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.

    Full Text Available Usher syndrome is an autosomal recessive disease with prevalence of 3–6/100.000 and is the most common syndrome that affects vision and hearing. Three subtypes are distinguished on the basis of different degree of hearing loss. All patients develop retinitis pigmentosa with night vision difficulties and constriction of visual field, and ultimately a decline in visual acuity and color vision. Future holds promise for gene therapy. We present a patient with typical clinical picture of Usher syndrome, who started noticing night vision problems at age 13. At age 25 he was operated on for posterior cortical cataracts. At age 34 he has only 5–10° of visual field remaining with 1.0 visual acuity in both eyes. Fundus autofluorescence imaging revealed a typical hyperautofluorescent ring on the border between normal and affected retina.

The aim was to undertake a systematic review of the existing research literature on dysmobility syndrome.Method: All articles reporting dysmobility syndrome were identified in a systematic review of Medline (Proquest, CINAHL, PubMed, PsycInfo, EMBASE, and Scopus databases. Key characteristics of identified studies were extracted and summarized.Results: The systematic review identified five papers (three cross-sectional, one case control, and one longitudinal study. No intervention studies were identified. Prevalence of dysmobility syndrome varied between studies (22%–34% in three of the studies. Dysmobility syndrome was shown to be associated with reduced function, increased falls and fractures, and a longitudinal study showed its significant association with mortality.Conclusion: Early research on dysmobility syndrome indicates that it may be a useful classification approach to identify older people at risk of adverse health outcomes and to target for early interventions. Future research needs to standardize the optimal mix of measures and cut points, and investigate whether balance performance may be a more useful factor than history of falls for dysmobility syndrome.

    Cushing's syndrome is the term used to describe a set of symptoms associated with hypercortisolism, which in most cases is caused by hypophysial microadenoma over-secreting adrenocorticotropic hormone. This endocrine disorder is often associated with psychiatric comorbidities. The most important include mood disorders, psychotic disorders, cognitive dysfunctions and anxiety disorders. The aim of this article was to review the prevalence, symptoms and consequences of psychiatric disorders in the course of Cushing's syndrome. We therefore performed a literature search using the following keywords: Cushing's syndrome and psychosis, Cushing's syndrome and mental disorders, Cushing's syndrome and depression, Cushing's syndrome and anxiety. The most prevalent psychiatric comorbidity of Cushing's syndrome is depression. Psychiatric manifestations can precede the onset of full-blown Cushing's syndrome and therefore be misdiagnosed. Despite the fact that treatment of the underlying endocrine disease in most cases alleviates psychiatric symptoms, the loss of brain volume persists. It is important to be alert to the symptoms of hypercortisolism in psychiatric patients to avoid misdiagnosis and enable them receiving adequate treatment.

    To create a comparative referential system for syndrome classification study by viewing from the thinking characteristics of TCM on syndrome differentiation dependent therapy (SDDT), through analyzing the thinking process of SDDT, and the basic features of disease, syndrome and prescription, combining the basic principles of modern evidence-based medicine and feasibility of establishing integrative disease-syndrome animal model. The practice of creating a comparative referential system based on clinical efficacy of prescription was discussed around syndrome pathogenesis and its relationship with disease and prescription, which was one of the important scientific problems in TCM syndrome study. The authors hold that, it may be one of the available approaches for the present study on integration of disease with syndrome by way of insisting on the thinking pathway of stressing the characteristics of TCM and intermerging with modern scientific design; on taking the efficacy of prescription as the comparative reference system to accumulate and improve unceasingly according to the TCM method of syndrome diagnosis inferred from effect of prescription with reverse thought (i.e., to differentiate syndrome from the effect of prescription), and thus build up the syndrome diagnostic standard on the solid clinical and scientific base.

    The refeeding syndrome can be defined as the metabolic alterations developed by the rapid nutrition repletion (oral, enteral as well as parenteral feeding) of severaly malnourished patients. Refeeding syndrome is a potentially fatal clinical condition and it is often underdiagnosed on non-specialized nutrition units. The most important key for its prevention is to identify patients at high risk for developing refeeding syndrome, before nutrition repletion. The present case describes the steps to prevent the refeeding syndrome as well as the clinical recommendations to restart nutrition support.

    The vast majority of sudden cardiac arrests occur in patients with structural heart disease and in approximately 10% of the cases, it can occur in those with structurally normal hearts. Brugada syndrome is an autosomal dominant sodium channelopathy that has been implicated in sudden deaths. Given their low prevalence, our knowledge about Brugada syndrome is still evolving. Apart from schizophrenia, there have been no reports of associated medical conditions. We recently encountered a patient with vascular Ehlers-Danlos syndrome who was also found to have Brugada syndrome. Both these conditions share some common clinical presentations including a propensity for sudden death.

    Marfan syndrome is a connective tissue disorder that can affect many organ systems. Affected patients present with orthopaedic manifestations of the syndrome during all phases of life. Pain caused by musculoskeletal abnormalities often requires definitive orthopaedic treatment. Orthopaedic surgeons must understand the phenotypes of Marfan syndrome so they can recognize when screening is warranted and can appropriately address the skeletal manifestations. Through medical advancements, patients with Marfan syndrome are living longer and more active lives. Knowledge of the latest diagnostic criteria for the disorder, as well as of advances in understanding the skeletal phenotype, clinical trials of medication therapy, and lifestyle considerations is important for orthopaedic surgeons who treat these patients because these clinicians often are the first to suspect Marfan syndrome and recommend screening.

    Maffucci's syndrome consists of multiple cutaneous hemangiomas, dyschondroplasia, and enchondromas with potential for malignant change. We report a case of a 33-year-old man with Maffucci's syndrome who presented with a several month history of nasal congestion, facial pain, and diminished vision in his left eye. Radiological studies showed a large soft tissue mass centered in the sinonasal area, extending bilaterally into maxillary sinuses and orbits with compression of left optic nerve. Biopsy of the mass showed esthesioneuroblastoma (olfactory neuroblastoma). Chemotherapy resulted in initial improvement, but the tumor recurred and did not respond to further treatment, resulting in his death. Sarcomatous tumors are reported in Maffucci's syndrome, but this is a rare case of a neuroendocrine tumor in a patient with Maffucci's syndrome. (orig.)

    Full Text Available The constellation of dyslipidemia (hypertriglyceridemia and low levels of high-density lipoprotein cholesterol, elevated blood pressure, impaired glucose tolerance, and central obesity is now classified as metabolic syndrome, also called syndrome X. In the past few years, several expert groups have attempted to set forth simple diagnostic criteria for use in clinical practice to identify patients who manifest the multiple components of the metabolic syndrome. These criteria have varied somewhat in specific elements, but in general, they include a combination of multiple and metabolic risk factors. The most widely recognized of the metabolic risk factors are atherogenic dyslipidemia, elevated blood pressure, and elevated plasma glucose. Individuals with these characteristics, commonly manifest a prothrombotic state as well as and a proinflammatory state. Atherogenic dyslipidemia consists of an aggregation of lipoprotein abnormalities including elevated serum triglyceride and apolipoprotein B (apoB, increased small LDL particles, and a reduced level of HDL cholesterol (HDL-C. The metabolic syndrome is often referred to as if it were a discrete entity with a single cause. Available data suggest that it truly is a syndrome, ie, a grouping of atherosclerotic cardiovascular disease (ASCVD risk factors, that probably has more than one cause. Regardless of cause, the syndrome identifies individuals at an elevated risk for ASCVD. The magnitude of the increased risk can vary according to the components of the syndrome present as well as the other, non-metabolic syndrome risk factors in a particular person.

    Full Text Available The urofacial syndrome is probably a subset of neurogenic bladder dysfunction syndromes characterized by detrusor-sphincter discoordination along with a characteristic inversion of facial expression with laughing. This characteristic facial expression can facilitate early detection of this disorder, which leads to poor bladder emptying with high residual urine, hydro-nephrosis with vesico-ureteral reflux and potentially renal failure if left untreated. The etiology of the urofacial syndrome is unknown. In our case, a 12-year-old boy of Middle-Eastern origin presented to the Outpatient Department of our hospital with left pyelonephritis, hydronephrosis and bladder dilatation. Voiding cystourethrography performed 15 days later revealed left vesicoureteral reflux. Cystoscopy revealed bladder trabeculation however an anatomic urethral obstruction was not noticed. Both, neurological examination and radiography of the lumbosacral spine were normal. Urodynamic evaluation revealed the typical findings of detrusor-sphincter discoordination.

Methods: We report a rare case of an 8-month-old male infant who presented with chronic anemia and gastrointestinal bleeding initially. Panendoscopy and abdominal computed tomography showed multiple polyposis throughout the entire alimentary tract leading to intussusception. Technetium-99m-labeled red blood cell (RBC) bleeding scan revealed the possibility of gastrointestinal tract bleeding in the jejunum. Histopathological examination on biopsy samples showed Peutz-Jeghers syndrome was excluded, whereas the diagnosis of juvenile polyposis syndrome was established. Results: Enteroscopic polypectomy is the mainstay of the treatment. However, polyps recurred and occupied the majority of the gastrointestinal tract in 6 months. Supportive management was given. The patient expired for severe sepsis at the age of 18 months. Conclusion: Juvenile polyposis syndrome is an inherited disease, so it is not possible to prevent it. Concerning of its poor outcome and high mortality rate, it is important that we should increase awareness and education of the parents at its earliest stages. PMID:27631205
