Clinical Features Birbeck granules (BGs) are rod-shaped cytoplasmic organelles found only in epidermal Langerhans cells (LCs). ... Furthermore, a BG-specific monoclonal antibody failed to stain the individual's LCs. ... Two observations indicated that these BG-negative LCs had normal antigen-presenting capacity. ... Mommaas et al. (1994) concluded that BGs are not a prerequisite for normal LC function. ... Expression of langerin with the W264R mutation in fibroblasts induced tubular-like structures that were not recognized by anti-BG antibodies and that lacked the characteristic structural features of BGs.

Baller–gerold Syndrome Wikipedia

Baller–Gerold syndrome Other names Craniosynostosis-radial aplasia syndrome, Craniosynostosis with radial defects The inheritance pattern of Baller-Gerold Syndrome Baller–Gerold syndrome ( BGS ) is a rare genetic syndrome that involves premature fusion of the skull bones and malformations of facial, forearm and hand bones. [1] The symptoms of Baller–Gerold syndrome overlap with features of a few other genetics disorders: Rothmund–Thomson syndrome and RAPADILINO syndrome . [1] The prevalence of BGS is unknown, as there have only been a few reported cases, but it is estimated to be less than 1 in a million. [1] The name of the syndrome comes from the researchers Baller and Gerold who discovered the first three cases. [2] Contents 1 Signs and symptoms 2 Genetics 3 Diagnosis 4 Treatment 5 References 6 External links Signs and symptoms [ edit ] The Coronal suture The most common and defining features of BGS are craniosynostosis and radial ray deficiency. [3] The observations of these features allow for a diagnosis of BGS to be made, as these symptoms characterize the syndrome. [4] Craniosynostosis involves the pre-mature fusion of bones in the skull. [1] The coronal craniosynostosis that is commonly seen in patients with BGS results in the fusion of the skull along the coronal suture . [5] Because of the changes in how the bones of the skull are connected together, people with BGS will have an abnormally shaped head, known as brachycephaly . [1] Features commonly seen in those with coronal craniosynostosis are bulging eyes, shallow eye pockets, and a prominent forehead. [5] Radial ray deficiency is another clinical characteristic of those with BGS, and results in the under-development ( hypoplasia ) or the absence ( aplasia ) of the bones in the arms and the hands. These bones include the radius, the carpal bones associated with the radius and the thumb. [1] [6] Oligodactyly can also result from radial ray deficiency, meaning that someone with BGS may have fewer than five fingers. [5] Radial ray deficiency that is associated with syndromes (such as BGS) occurs bi-laterally, affecting both arms. [6] Some of the other clinical characteristics sometimes associated with this disorder are growth retardation and poikiloderma . [5] Although the presentation of BGS may differ between individuals, these characteristics are often observed. ... In order for someone to have BGS, they need to have two mutant copies of the gene. ... You can help by adding to it . ( July 2017 ) Treatment [ edit ] While there is no cure for BGS, symptoms can be treated as they arise. ...

Summary Clinical characteristics. Baller-Gerold syndrome (BGS) can be suspected at birth in an infant with craniosynostosis and upper limb abnormality. ... Diagnosis/testing. The diagnosis of BGS is established in a proband with typical clinical findings and/or the identification of biallelic pathogenic variants in RECQL4 by molecular genetic testing. ... Clinical Characteristics Clinical Description Since the original description of Baller-Gerold syndrome (BGS) by Baller [1950] and Gerold [1959], fewer than 40 individuals with BGS have been reported [Mégarbané et al 2000, Van Maldergem et al 2006, Debeljak et al 2009, Siitonen et al 2009, Piard et al 2015, Kaneko et al 2017]. BGS can be suspected at birth in an infant with craniosynostosis and upper limb abnormality. ... Differential Diagnosis The major differential diagnosis for Baller-Gerold syndrome (BGS) comprises the allelic disorders Rothmund-Thomson syndrome and RAPADILINO syndrome (OMIM 266280).
Baller-Gerold Syndrome OMIM

A number sign (#) is used with this entry because of evidence that Baller-Gerold syndrome (BGS) is caused by homozygous or compound heterozygous mutation in the RECQL4 gene (603780) on chromosome 8p24. ... The finding of premature centromere separation pointed to Roberts syndrome rather than BGS as indicated by Huson et al. (1990). ... The patient of Gripp et al. (1999) illustrated the practical significance of the distinction. BGS has been thought to be an autosomal recessive disorder; the Saethre-Chotzen syndrome is an autosomal dominant disorder. ... Molecular Genetics Van Maldergem et al. (2006) pointed out the clinical overlap between the BGS and Rothmund-Thomson syndrome (RTS; 268400) and RAPADILINO syndrome (266280). Because patients with RAPADILINO syndrome and a subset of patients with RTS have mutations in the RECQL4 gene (603780), they reassessed 2 previously reported BGS families and found causal mutations in RECQL4 in both.
Baller-Gerold Syndrome Orphanet

Baller-Gerold syndrome is characterized by the association of coronal craniosynostosis with radial ray anomalies (oligodactyly, aplasia or hypoplasia of the thumb, aplasia or hypoplasia of the radius). Epidemiology Around 30 cases have been reported but the prevalence of the syndrome is unknown. Clinical description Craniosynostosis and radial ray anomalies present at birth and are associated with facial dysmorphism (brachycephaly, ocular exophthalmia, frontal bossing, nasal hypoplasia, small mouth, ogival palate). An inconstant poikiloderma can appear during the first months of life. Delayed growth is nearly always present, usually around -4SD. Patellar aplasia or hypoplasia can be observed during childhood.

Baller-Gerold syndrome (BGS) is a rare condition primarily affecting the way the bones of the skull and limbs grow. ... In addition, they may have a characteristic skin condition that includes patches of discoloration and skin breakdown ( poikiloderma ). People with BGS may have growth delay and be at increased risk for certain types of cancer. Intelligence is usually normal. Most cases of BGS are caused by alterations in the RECQL4 gene.
Baller-Gerold Syndrome MedlinePlus

Baller-Gerold syndrome is a rare condition characterized by the premature fusion of certain skull bones (craniosynostosis) and abnormalities of bones in the arms and hands. People with Baller-Gerold syndrome have prematurely fused skull bones, most often along the coronal suture, the growth line that goes over the head from ear to ear. Other sutures of the skull may be fused as well. These changes result in an abnormally shaped head, a prominent forehead , and bulging eyes with shallow eye sockets (ocular proptosis ). Other distinctive facial features can include widely spaced eyes (hypertelorism ), a small mouth , and a saddle-shaped or underdeveloped nose. Bone abnormalities in the hands include missing fingers (oligodactyly ) and malformed or absent thumbs .

However in some cases, a pancreatic NET occurs outside of the pancreas. A NET arises from cells that produce hormones, so the tumor can also produce hormones. ... Pancreatic NETs are called either functional or nonfunctional. A functional pancreatic NET causes specific symptoms because it makes extra hormones, such as gastrin, insulin, or glucagon. ... Pancreatic NETs can be hard to diagnosis, often not identified until 5 to 10 years after they begin to grow. Most pancreatic NETs are not inherited and occur sporadically in people with no family history of NETs.

Neuroendocrine Tumor GARD

A neuroendocrine tumor (NET) is a rare type of tumor that arises from specialized body cells called neuroendocrine cells . ... Pancreatic neuroendocrine tumors (also called islet cell tumors) - NETs that typically arise in the pancreas, although they can occur outside the pancreas. A p heochromocytoma is another, rarer type of NET that usually develops in the adrenal gland , but can also arise in other parts of the body. ... Functional NETs produce a specific set of symptoms due to the production of excess hormones, while non-functional NETs generally do not cause specific symptoms. In many cases, a person has no symptoms until the tumor spreads to the liver and/or impairs the function of an organ or system. This can make NETs very hard to diagnose. The majority of NETs are not inherited and occur sporadically in people with no family history of NETs.

Orthostatic Intolerance Wikipedia

Human disease Orthostatic intolerance ( OI ) is the development of symptoms when standing upright which are relieved when reclining . [1] There are many types of orthostatic intolerance. OI can be a subcategory of dysautonomia , a disorder of the autonomic nervous system [2] occurring when an individual stands up. [3] There is a substantial overlap between syndromes of orthostatic intolerance on the one hand, and either chronic fatigue syndrome (CFS) or fibromyalgia (FM) on the other. [4] It affects more women than men (female-to-male ratio is at least 4:1), usually under the age of 35. [5] Orthostatic intolerance occurs in humans because standing upright is a fundamental stressor and requires rapid and effective circulatory and neurologic compensations to maintain blood pressure , cerebral blood flow , and consciousness . When a human stands, approximately 750 mL of thoracic blood is abruptly translocated downward. People who suffer from OI lack the basic mechanisms to compensate for this deficit. [1] Changes in heart rate , blood pressure, and cerebral blood flow that produce OI may be caused by abnormalities in the interactions between blood volume control, the cardiovascular system , the nervous system and circulation control system . [6] Contents 1 Signs and symptoms 1.1 Acute OI 1.2 Chronic OI 2 Causes 3 Diagnosis 4 Management 5 Notable case 6 See also 7 References 8 External links Signs and symptoms [ edit ] Orthostatic intolerance is divided, roughly based on patient history, in two variants: acute and chronic . Acute OI [ edit ] Patients who suffer from acute OI usually manifest the disorder by a temporary loss of consciousness and posture , with rapid recovery (simple faints , or syncope ), as well as remaining conscious during their loss of posture.

[10] Often, it begins after a viral infection, surgery, or pregnancy. [8] Risk factors include a family history of the condition. [1] Diagnosis in adults is based on an increase in heart rate of more than 30 beats per minute within ten minutes of standing up that is accompanied by symptoms. [1] Low blood pressure with standing , however, does not occur. [1] Other conditions which can cause similar symptoms, such as dehydration , heart problems, adrenal insufficiency , epilepsy , and parkinson disease , must not be present. [7] Treatment may include avoiding factors that bring on symptoms, increasing dietary salt and water, small and frequent meals, [11] avoidance of immobilization, [11] compression stockings , exercise program, and medications. [12] [13] [1] [14] Medications used may include beta blockers , [15] pyridostigmine , [16] midodrine [17] or fludrocortisone . [1] More than 50% of people whose condition was triggered by a viral infection get better within five years. [8] About 80% have symptomatic improvement with treatment, but 25 percent of patients are still unable to work. [9] [8] Retrospective studies has shown that five years after diagnosis 19% had a full resolution of symptom. [18] It is estimated that 500,000 people are affected in the United States. [19] The average age of onset is 20 years old, and it occurs about five times more frequently in females. [1] Signs and symptoms [ edit ] In adults the primary symptom is an increase in heart rate of more than 30 beats per minute within ten minutes of standing up. [1] [20] The resulting heart rate is typically more than 120 beats per minute. [1] For people aged between 12 and 19, the minimum increase for diagnosis is 40 beats per minute. [21] This symptom is known as orthostatic (upright) tachycardia (fast heart rate). It occurs without any coinciding drop in blood pressure, as that would indicate orthostatic hypotension . [20] Certain medications to treat POTS may cause orthostatic hypotension. It is accompanied by other features of orthostatic intolerance —symptoms that develop in an upright position and are relieved by reclining. [20] These orthostatic symptoms include palpitations , light-headedness , chest discomfort, shortness of breath , [20] nausea, weakness or "heaviness" in the lower legs, blurred vision , and cognitive difficulties. [1] Symptoms may be exacerbated with prolonged sitting, prolonged standing, alcohol, heat, exercise, or eating a large meal. [ citation needed ] In up to one third of people with POTS, [1] fainting occurs in response to postural changes or exercise. [22] Migraine -like headaches are common, sometimes with symptoms worsening in an upright position ( orthostatic headache ). [22] 40-50% of patients with POTS develop acrocyanosis of extremities, a reddish-purple color in the legs and/or hands when they stand (indicative of blood pooling). [23] [22] [24] 48% of people with POTS report chronic fatigue and 32% report sleep disturbances . [25] [26] [27] [28] Others exhibit only the cardinal symptom of orthostatic tachycardia. [22] Additional symptoms are varied, and may include excessive sweating, a lack of sweating, heat intolerance, digestive issues such as bloating, nausea, indigestion, constipation, and diarrhea, a flu-like feeling, coat-hanger pain, forgetfulness, brain fog, and presyncope . [29] Brain fog [ edit ] One of the most disabling and prevalent symptoms in POTS is " brain fog ", [30] a term used by patient to describe the cognitive difficulties they experience. In one survey of 138 POTS patients, brain fog was defined as “forgetful” (91%), “difficulty thinking” (89%), and “difficulty focusing” (88%). Other common description was "Difficulty processing what others say" (80%), Confusion (71%), Lost (64 %), and "Thoughts moving too quickly" (40%) [31] The same survey described the most common triggers of brain fog to be fatigue (91%), lack of sleep (90%), prolonged standing (87%) and dehydration (86%). [ citation needed ] Neuropsychological testing has shown that a POTS-patient has reduced attention (Ruff 2&7 speed and WAIS-III digits forward), short-term memory ( WAIS-III digits back), cognitive processing speed ( Symbol digits modalities test ) and executive function ( Stroop word color and trails B ). [32] [33] [34] A potential cause for brain fog is a decrease in cerebral blood flow (CBF), especially in upright position. [35] [36] [37] Another theory is that interoception of excessive autonomic activity causes interoceptive prediction errors (PE) to occur. [38] A prediction error is the mismatch between a prior expectation and reality. [39] This would cause anxiety which then overwhelms the consciousness of pots-patient causing cognitive-affective symptoms.
Orthostatic Intolerance OMIM

A number sign (#) is used with this entry because of evidence that orthostatic intolerance is caused by heterozygous mutation in the gene encoding the norepinephrine transporter (SLC6A2; 163970) on chromosome 16q12. One such family has been reported. Clinical Features Orthostatic intolerance is a syndrome characterized by adrenergic symptoms that occur when an upright posture is assumed: the heart rate increases by at least 30 beats per minute, without orthostatic hypotension (Jacob et al., 1997). Most patients with orthostatic intolerance are women between the ages of 20 and 50 years (Low et al., 1995). This syndrome, first described by Da Costa (1871), has been called soldiers heart (Fraser and Wilson, 1918), neurocirculatory asthenia (Wooley, 1976), and mitral valve prolapse syndrome (Boudoulas et al., 1980). It is similar in many respects to chronic fatigue syndrome (Schondorf and Freeman, 1999).

The mosquitoes remain on the wall until they fall down dead on the floor. Insecticide treated nets [ edit ] A mosquito net in use. Mosquito nets help keep mosquitoes away from people and reduce infection rates and transmission of malaria. Nets are not a perfect barrier and are often treated with an insecticide designed to kill the mosquito before it has time to find a way past the net. Insecticide-treated nets are estimated to be twice as effective as untreated nets and offer greater than 70% protection compared with no net. [73] Between 2000 and 2008, the use of ITNs saved the lives of an estimated 250,000 infants in Sub-Saharan Africa. [74] About 13% of households in Sub-Saharan countries owned ITNs in 2007 [75] and 31% of African households were estimated to own at least one ITN in 2008. ... That number increased to 20.3 million (18.5%) African children using ITNs in 2007, leaving 89.6 million children unprotected [76] and to 68% African children using mosquito nets in 2015. [77] Most nets are impregnated with pyrethroids , a class of insecticides with low toxicity . ... According to the WHO and UNICEF, deaths attributable to malaria in 2015 were reduced by 60% [77] from a 2000 estimate of 985,000, largely due to the widespread use of insecticide-treated nets and artemisinin-based combination therapies. [74] In 2012, there were 207 million cases of malaria.

Malaria, Susceptibility To OMIM

A reduction in mortality greater than that attributable directly to malaria had been observed after the prevention of malaria by insecticides, chemoprophylaxis, and insecticide-impregnated bed nets. Previous observations that direct malaria mortality cannot account for observed hemoglobin S gene frequencies suggest that the findings of this study may apply equally to other malaria resistance genes. ... Although the relative strength of the protection is less than that of the sickle-cell variant, the greater frequency of the DQB1 (see HLA-DQB1; 604305) polymorphism makes the net effect on resistance to malaria comparable.
Malaria Orphanet

A life-threatening parasitic disease caused by Plasmodium ( P. ) parasites that are transmitted by Anophles mosquito bites to humans and is typically clinically characterized by attacks of fever, headache, chills and vomiting.
Malaria GARD

Malaria is a serious and sometimes fatal disease caused by a parasite that commonly infects a certain type of mosquito which feeds on humans. Infection with malaria parasites may result in a wide variety of symptoms, ranging from absent or very mild symptoms to severe disease and even death. People who get malaria are typically very sick with high fevers, shaking chills, and flu-like illness. In general, malaria is a curable disease if diagnosed and treated promptly and correctly. Treatment depends on many factors including disease severity, the species of malaria parasite causing the infection and the part of the world in which the infection was acquired.
Malaria Mayo Clinic

To reduce malaria infections, world health programs distribute preventive drugs and insecticide-treated bed nets to protect people from mosquito bites. The World Health Organization has recommended a malaria vaccine for use in children who live in countries with high numbers of malaria cases. Protective clothing, bed nets and insecticides can protect you while traveling. ... Sprays containing permethrin are safe to apply to clothing. Sleep under a net. Bed nets, particularly those treated with insecticides, such as permethrin, help prevent mosquito bites while you are sleeping.

Pancreatic Neuroendocrine Tumor Wikipedia

PanNETs are a type of neuroendocrine tumor , representing about one third of gastroenteropancreatic neuroendocrine tumors (GEP-NETs). Many PanNETs are benign , while some are malignant . ... However, morphological imaging alone is not sufficient for a definite diagnosis [14] [16] On biopsy , immunohistochemistry is generally positive for chromogranin and synaptophysin . [17] Genetic testing thereof typically shows altered MEN1 and DAXX / ATRX . [17] Staging [ edit ] The 2010 WHO classification of tumors of the digestive system grades all the neuroendocrine tumors into three categories, based on their degree of cellular differentiation (from well-differentiated "NET G1" through to poorly-differentiated "NET G3"). ... Combinations of several medicines have been used, such as doxorubicin with streptozocin and fluorouracil (5-FU) [12] and capecitabine with temozolomide. [ citation needed ] Although marginally effective in well-differentiated PETs, cisplatin with etoposide has some activity in poorly differentiated neuroendocrine cancers (PDNECs), [12] particularly if the PDNEC has an extremely high Ki-67 score of over 50%. [8] : 30 Several targeted therapy agents have been approved in PanNETs by the FDA based on improved progression-free survival (PFS): everolimus (Afinitor) is labeled for treatment of progressive neuroendocrine tumors of pancreatic origin in patients with unresectable, locally advanced or metastatic disease. [20] [21] The safety and effectiveness of everolimus in carcinoid tumors have not been established. [20] [21] sunitinib (Sutent) is labeled for treatment of progressive, well-differentiated pancreatic neuroendocrine tumors in patients with unresectable locally advanced or metastatic disease. [22] [23] Sutent also has approval from the European Commission for the treatment of 'unresectable or metastatic, well-differentiated pancreatic neuroendocrine tumors with disease progression in adults'. [24] A phase III study of sunitinib treatment in well differentiated pNET that had worsened within the past 12 months (either advanced or metastatic disease) showed that sunitinib treatment improved progression-free survival (11.4 months vs. 5.5 months), overall survival , and the objective response rate (9.3% vs. 0.0%) when compared with placebo. [25] Genetics [ edit ] Pancreatic neuroendocrine tumors may arise in the context of multiple endocrine neoplasia type 1 , Von Hippel–Lindau disease , neurofibromatosis type 1 (NF-1) or tuberose sclerosis (TSC) [26] [27] Analysis of somatic DNA mutations in well-differentiated pancreatic neuroendocrine tumors identified four important findings: [28] [6] as expected, the genes mutated in NETs, MEN1 , ATRX , DAXX , TSC2 , PTEN and PIK3CA , [28] are different from the mutated genes previously found in pancreatic adenocarcinoma . [29] [30] one in six well-differentiated pancreatic NETs have mutations in mTOR pathway genes, such as TSC2 , PTEN and PIK3CA . [28] The sequencing discovery might allow selection of which NETs would benefit from mTOR inhibition such as with everolimus , but this awaits validation in a clinical trial . mutations affecting a new cancer pathway involving ATRX and DAXX genes were found in about 40% of pancreatic NETs. [28] The proteins encoded by ATRX and DAXX participate in chromatin remodeling of telomeres ; [31] these mutations are associated with a telomerase -independent maintenance mechanism termed ALT (alternative lengthening of telomeres) that results in abnormally long telomeric ends of chromosomes . [31] ATRX / DAXX and MEN1 mutations were associated with a better prognosis . [28] References [ edit ] ^ Burns WR, Edil BH (March 2012).

Reticulate Acropigmentation Of Kitamura OMIM

A number sign (#) is used with this entry because of evidence that reticulate acropigmentation of Kitamura (RAK) is caused by heterozygous mutation in the ADAM10 gene (602192) on chromosome 15q21. Description Reticulate acropigmentation of Kitamura (RAK) is a rare pigmentary disorder that usually shows an autosomal dominant pattern of inheritance with high penetrance. Typical features include reticulate, slightly depressed, sharply demarcated brown macules without hypopigmentation, affecting the dorsa of the hands and feet in the first or second decade of life. The macules gradually darken and extend to the proximal regions of the extremities; progression of the eruptions stops in middle age. The increased pigmentation is found on the flexor aspects of the wrists, neck, patella, and olecranon.

Saethre-Chotzen Syndrome GARD

Saethre-Chotzen syndrome is a genetic condition characterized by the premature fusion of certain skull bones (craniosynostosis). This early fusion prevents the skull from growing normally and affects the shape and symmetry of the head and face. Other features may include webbing of certain fingers or toes (syndactyly), small or unusually shaped ears, short stature, and abnormalities of the bones in the spine (the vertebrae). The signs and symptoms of Saethre-Chotzen syndrome vary widely, even among affected individuals in the same family. Mutations (variants) in the TWIST1 gene cause most cases of Saethre-Chotzen syndrome.
Saethre-Chotzen Syndrome Orphanet

A syndrome characterized by unilateral or bilateral coronal synostosis, facial asymmetry, ptosis, strabismus and small ears with prominent superior and/or inferior crus, among other less common manifestations. Epidemiology Saethre-Chotzen syndrome (SCS) prevalence ranges from 1/25,000 to 1/50,000 livebirths. Clinical description SCS has a variable spectrum of manifestations. Classic SCS presents at birth with synostosis of coronal (less commonly in conjunction with sagittal, metopic or lambdoid) sutures resulting in abnormal skull shape, facial asymmetry, low frontal hairline, ptosis, strabismus, tear duct stenosis and small ears with prominent crus. Brachydactyly, broad toes, partial cutaneous syndactyly of digits 2 and 3 of the hand, duplicated distal phalanx of the hallux are also often present. Intelligence is normal in most, but mild to severe developmental delay has been reported, primarily in cases with a large genomic deletion.

A number sign (#) is used with this entry because of evidence that the Saethre-Chotzen syndrome (SCS) is caused by heterozygous mutation in the TWIST1 gene (601622) on chromosome 7p21. See also Muenke syndrome (602849), which is caused by a mutation in the FGFR3 gene (P250R; 134934.0014) and has a similar overlapping phenotype to SCS. In addition, at least 1 individual with a phenotype of SCS has been described with a mutation in the FGFR2 gene (176943.0023). Description Saethre-Chotzen syndrome is characterized by craniosynostosis, facial dysmorphism, and hand and foot abnormalities. Coronal synostosis resulting in brachycephaly is the most frequent cranial abnormality observed, and the most common facial features are asymmetry, hypertelorism, and maxillary hypoplasia.

Insulinoma Wikipedia

Insulinoma Pathology of pancreatic endocrine tumor (insulinoma). Specialty Oncology An insulinoma is a tumor of the pancreas that is derived from beta cells and secretes insulin . It is a rare form of a neuroendocrine tumor . Most insulinomas are benign in that they grow exclusively at their origin within the pancreas, but a minority metastasize . Insulinomas are one of the functional pancreatic neuroendocrine tumor (PNET) group ("functional" because it increases production of insulin). [1] In the Medical Subject Headings classification, insulinoma is the only subtype of "islet cell adenoma". [2] Beta cells secrete insulin in response to increases in blood glucose . The resulting increase in insulin acts to lower blood glucose back to normal levels, at which point further secretion of insulin is stopped. In contrast, the secretion of insulin by insulinomas is not properly regulated by glucose, and the tumors continue to secrete insulin causing glucose levels to fall further than normal.

Insulinoma is the most common type of functioning pancreatic neuroendocrine tumor (see this term) characterized most commonly by a solitary, small pancreatic lesion that causes hyperinsulinemic hypoglycemia. Epidemiology The incidence in the general population is 1/1,000,000-1/250,000 (but higher in autopsy studies). There is a slight female predominance. It is the most common endogenous cause of hyperinsulinemic hypoglycemia. Malignant insulinoma has an incidence 0.01/100,000 in Europe. Clinical description Insulinoma can present at any age but the median age of diagnosis is in the 5th decade of life. It manifests with various autonomic and neuroglycopenic symptoms such as tremor, palpitations, weakness, diaphoresis, hyperphagia, visual disturbances, confusion, behavioral and personality changes, seizures and coma.

Sneddon Syndrome GARD

It is primarily characterized by livedo reticularis (net-like patterns of discoloration on the skin) and neurological abnormalities.

Sneddon Syndrome OMIM

A number sign (#) is used with this entry because of evidence that Sneddon syndrome (SNDNS) is caused by compound heterozygous mutation in the CECR1 gene (ADA2; 607575) on chromosome 22q11. One such family has been reported. Mutation in the ADA2 gene can also cause vasculitis, autoinflammation, immunodeficiency, and hematologic defects syndrome (VAIHS; 615688), which shows earlier onset. Description Sneddon syndrome is a noninflammatory arteriopathy characterized by onset of livedo reticularis in the second decade and onset of cerebrovascular disease in early adulthood (summary by Bras et al., 2014). Livedo reticularis occurs also with polyarteritis nodosa, systemic lupus erythematosus, and central thrombocythemia, any one of which may be accompanied by cerebrovascular accidents (Bruyn et al., 1987). Clinical Features Sneddon (1965) described 6 patients (5 females, 1 male), varying in age from 20 to 48 years, who had association of livedo reticularis with cerebrovascular accident.
Sneddon's Syndrome Wikipedia

Sneddon syndrome Other names Ehrmann-Sneddon syndrome, Livedo racemosa-cerebrovascular accident syndrome, Livedo reticularis-cerebrovascular accident syndrome [1] This condition is inherited in an autosomal recessive manner [2] Specialty Rheumatology Sneddon's syndrome [1] is a form of arteriopathy characterized by several symptoms, including: Severe, transient neurological symptoms or stroke Livedo reticularis , or livedo racemosa Contents 1 Signs and symptoms 2 Pathogenesis 3 Diagnosis 4 Treatment 5 Epidemiology 6 History 7 See also 8 References 9 Further reading 10 External links Signs and symptoms [ edit ] Sneddon's syndrome generally manifests with stroke or severe, transient neurological symptoms, and a skin rash ( livedo reticularis ). Livedo reticularis appears as a bluish-purple, netlike mottling of the skin. Sneddon's syndrome may instead present with livedo racemosa , which involves larger, less organized patches of bluish-purple mottling of the skin. Both are generally found first in the extremities, both worsen in cold and either may occur without Sneddon's Syndrome or any other systemic disease. [ citation needed ] Sneddon's Syndrome can be characterized by: transient amnesia , transient aphasia , palsy , headaches , hypertension, transient ischemic attacks (TIA), stroke , [3] coronary disease and dementia. [4] The skin manifestations may precede the neurologic symptoms by years. [3] Pathogenesis [ edit ] Sneddon's syndrome is a progressive, noninflammatory arteriopathy leading to the characteristic skin condition and to cerebrovascular problems, including stroke, transient ischemic attack (TIA), severe but transient neurological symptoms thought to be caused by cerebral vasospasm, coronary disease and early-onset dementia. Progressive compromise of arterial linings in Sneddon's produces clotting, for which high-dose warfarin is most commonly prescribed, and can also cause the development of systemic arterial plaque when cholesterol levels are normal. [ citation needed ] Diagnosis [ edit ] There are no diagnostic tests on which all Sneddon's patients will have abnormal results, although brain MRI and skin biopsy are often abnormal.
Adenosine Deaminase 2 Deficiency MedlinePlus

Signs and symptoms that can occur with ADA2 deficiency include fevers that are intermittent, meaning they come and go; areas of net-like, mottled skin discoloration called livedo racemosa; an enlarged liver and spleen (hepatosplenomegaly); and recurrent strokes affecting structures deep in the brain that can start in the first few years of life.
Sneddon Syndrome Orphanet

Clinical description The mean age of onset of neurological symptoms is 39 years, though the livedo is generally observed up to 10 years earlier and sometimes since childhood. Livedo racemosa is a persistent net-like violaceous-cyanotic, mottled discoloration of the skin affecting primarily the legs and arms, but also involving the buttocks and the trunk, and that is exacerbated by cold or pregnancy.

Suprabulbar Paresis, Congenital OMIM

Clinical Features Called the Worster-Drought (1974) syndrome because of the review of 200 cases by that physician, congenital suprabulbar paresis is characterized by selective weakness and impairment of movement of the orbicularis oris muscle, tongue and soft palate leading to dysarthria and troublesome drooling. In severe cases there is involvement of the pharyngeal and laryngeal muscles in early life. The child cannot protrude his tongue or move it within the mouth and is unable to round the lips to whistle or blow, but since other facial muscles are unaffected, he can smile normally and close his eyes. Worster-Drought (1974) noted familial occurrence in 12 of his 200 patients. Patton et al. (1986) described 4 affected males in 3 sibships of 3 generations of a family.
Worster-Drought Syndrome Orphanet

Worster-Drought syndrome (WDS) is a form of cerebral palsy characterized by congenital pseudobulbar (suprabulbar) paresis manifesting as selective weakness of the lips, tongue and soft palate, dysphagia, dysphonia, drooling and jaw jerking. Epidemiology Prevalence is estimated at around 1/25,000-30,000, with a male predominance (male to female sex ratio: 3:1). Clinical description Mean age at diagnosis is 6 years. The main clinical features are spasticity and limited movements around the mouth and throat from an early age, and brisk jaw jerks. In severe cases, the muscles of the pharynx and larynx are also involved. Epilepsy, learning difficulties and behavioral disturbances are common.
Worster Drought Syndrome GARD

Worster-Drought syndrome (WDS) is a condition that affects the muscles of the mouth and throat; it is considered a type of cerebral palsy . The main symptoms of WDS include difficulties with drooling, swallowing and speaking. Some affected individuals may also have challenges with intelligence, behavior, or seizures. The cause of WDS is currently unknown, though it is believed that both genetic and environmental factors influence the development of this condition.

Kbg Syndrome GeneReviews

Summary Clinical characteristics. KBG syndrome is typically characterized by macrodontia (especially of the upper central incisors), characteristic facial features (triangular face, brachycephaly, synophrys, widely spaced eyes, broad or bushy eyebrows, prominent ears, prominent nasal bridge, bulbous nose, anteverted nares, long philtrum, and thin vermilion of the upper lip), short stature, developmental delay / intellectual disability, and behavioral issues. Affected individuals may have feeding difficulties (particularly in infancy), skeletal anomalies (brachydactyly, large anterior fontanelle with delayed closure, scoliosis), hearing loss (conductive, mixed, and sensorineural), seizure disorder, and brain malformations. There is significant variability in the clinical findings, even between affected members of the same family. Diagnosis/testing. The diagnosis of KBG syndrome is confirmed in a proband by detection of either a heterozygous pathogenic variant in ANKRD11 or deletion of 16q24.3 that includes ANKRD11 . Management. Treatment of manifestations. Surgical corrections and/or speech therapy for palatal anomalies; nasogastric tube feeding in infants; pharmacologic treatment for gastroesophageal reflux disease; pressure-equalizing tubes and/or tonsillectomy/adenoidectomy for chronic otitis media; consideration of amplification for hearing loss; consideration of growth hormone therapy for short stature and medication to arrest puberty for premature pubertal development; standard treatment of seizure disorder, undescended testis in males, congenital heart defects, strabismus / refractive errors, and developmental disabilities.
Kbg Syndrome OMIM

A number sign (#) is used with this entry because of evidence that KBG syndrome (KBGS) is caused by heterozygous mutation in the ANKRD11 gene (611192) on chromosome 16q24. Description KBG syndrome is characterized by macrodontia of the upper central incisors, distinctive craniofacial findings, short stature, skeletal anomalies, and neurologic involvement that includes global developmental delay, seizures, and intellectual disability (summary by Sirmaci et al., 2011). Sirmaci et al. (2011) noted that it is likely that KBG syndrome is underdiagnosed, since many of the features, including intellectual disability, are mild, and none of the features is a prerequisite for diagnosis. Clinical Features Herrmann et al. (1975) described 2 families in which multiple members had short stature, characteristic facies (telecanthus, wide eyebrows, brachycephaly), macrodontia, mental retardation, and skeletal anomalies (abnormal vertebrae, short metacarpals, short femoral necks). Male-to-male transmission occurred in 1 family. (The designation KBG syndrome follows Opitz's practice of using the initials of affected families' surnames.)

Kbg Syndrome MedlinePlus

KBG syndrome is a rare disorder that affects several body systems. "KBG" represents the surname initials of the first families diagnosed with the disorder. Common signs and symptoms in individuals with this condition include unusual facial features, skeletal abnormalities, and intellectual disability. A characteristic feature of KBG syndrome is unusually large upper front teeth (macrodontia ). Other distinctive facial features include a wide, short skull (brachycephaly ), a triangular face shape, widely spaced eyes (hypertelorism), wide eyebrows that may grow together in the middle (synophrys ), a prominent nasal bridge, a long space between the nose and upper lip (long philtrum ), and a thin upper lip . A common skeletal abnormality in people with KBG syndrome is slowed mineralization of bones (delayed bone age); for example, an affected 3-year-old child may have bones more typical of a child of 2.
Kbg Syndrome GARD

KBG syndrome is a rare condition characterized mainly by skeletal abnormalities, distinctive facial features, and intellectual disability. Specific signs and symptoms may include delayed bone age; abnormalities of the bones of the spine, ribs, and/or hands; large teeth (macrodontia); short stature; developmental delay; and behavioral or emotional issues. Less common features may include hearing loss, seizures, and congenital heart defects. In some cases, KBG syndrome is caused by a mutation in the ANKRD11 gene and is inherited in an autosomal dominant manner. In other cases, the genetic cause is unclear. Some affected people inherit the condition from a parent, while in other people it occurs sporadically .
