Paraneoplastic cerebellar degeneration (PCD) is a rare anti-Yo mediated paraneoplastic syndromes rarely that is infrequently associated with breast cancer. We present a case of a 52-year-old female presenting with diplopia, gait instability, dysarthria, dysphagia, nystagmus, and, most notably, new onset paroxysmal episodes of uncontrollable crying concerning for pseudobulbar affect (PBA). Serologic testing showed anti-Yo antibodies. The patient was found to have stage IIIA breast cancer as the inciting cause of the paraneoplastic syndrome. The patient was treated with neoadjuvant chemotherapy, modified radical mastectomy, adjuvant Herceptin, and pertuzumab. She was given IVIG for paraneoplastic syndrome, antidepressants, and dextromethorphan-quinidine (Nuedexta), the first FDA-approved therapy for PBA. With multimodality therapy, she demonstrated significant improvement in neurologic and mood symptoms associated with PCD and PBA.

Epilepsy can be a manifestation of paraneoplastic syndromes which are the consequence of an immune reaction to neuronal elements driven by an underlying malignancy affecting other organs and tissues. The antibodies commonly found in paraneoplastic encephalitis can be divided into two main groups depending on the target antigen: 1) antibodies against neuronal cell surface antigens, such as against neurotransmitter (N-methyl-d-aspartate (NMDA), alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA), gamma-aminobutyric acid (GABA)) receptors, ion channels (voltage-gated potassium channel (VGKC)), and channel-complex proteins (leucine rich, glioma inactivated-1 glycoprotein (LGI1) and contactin-associated protein-2 (CASPR2)) and 2) antibodies against intracellular neuronal antigens (Hu/antineuronal nuclear antibody-1 (ANNA-1), Ma2/Ta, glutamate decarboxylase 65 (GAD65), less frequently to CV2/collapsin response mediator protein 5 (CRMP5)). In this review, we provide a comprehensive survey of the current literature on paraneoplastic epilepsy indexed by the associated onconeuronal antibodies. While a range of seizure types can be seen with paraneoplastic syndromes, temporal lobe epilepsy is the most common because of the association with limbic encephalitis. Early treatment of the paraneoplastic syndrome with immune modulation/suppression may prevent the more serious potential consequences of paraneoplastic epilepsy. Copyright © 2016 Elsevier Inc.

Paraneoplastic Neurological Disorder in Nasopharyngeal Carcinoma.

PubMed

Ng, Sze Yin; Kongg, Min Han; Yunus, Mohd Razif Mohamad

2017-03-01

Paraneoplastic neurological disorder (PND) is a condition due to immune cross-reactivity between the tumour cells and the normal tissue, whereby the "onconeural" antibodies attack the normal host nervous system. It can present within weeks to months before or after the diagnosis of malignancies. Nasopharyngeal carcinoma is associated with paraneoplastic syndrome, for example, dermatomyositis, and rarely with a neurological disorder. We report on a case of nasopharyngeal carcinoma with probable PND. Otolaryngologists, oncologists and neurologists need to be aware of this condition in order to make an accurate diagnosis and to provide prompt treatment.

Paraneoplastic glomerulonephritis is a rare complication of malignancy that is frequently mistaken for idiopathic glomerulonephritis. Failure to recognize paraneoplastic glomerulonephritis can subject patients to ineffective and potentially harmful therapy. Pathology of paraneoplastic glomerulonephritis varies between different types of malignancies. This Review describes the association of glomerulonephritis with both solid tumors and hematological malignancies The pathogenetic mechanisms of many glomerular lesions seem to relate to altered immune responses in the presence of a malignancy Studies in the Buffalo/Mna rat model of spontaneous thymoma and nephrotic syndrome indicate that polarization of the immune response toward a T-helper-2 (TH2) profile has an important role in the development of thymoma-associated glomerular lesions. Furthermore, overexpression of the TH2 cytokine interleukin 13 in transgenic rats induces minimal change disease. Such findings from experimental studies might facilitate the identification of biomarkers that can distinguish paraneoplastic glomerulonephritis from idiopathic and other secondary glomerulonephritides. This Review describes potential pathogenetic mechanisms for paraneoplastic glomerulonephritides associated with different malignancies and highlights the need for a multidisciplinary approach to the management of patients with paraneoplastic glomerulonephritis.

Paraneoplastic syndromes are most frequently associated with small cell lung carcinoma, hematologic and gynecologic malignancies while reports in head and neck cancer are rare. We present the case of a 60-year old female patient who developed paraneoplastic cerebellar degeneration upon locoregional recurrence of a poorly differentiated spindle cell carcinoma of the nasal cavity and paranasal sinus. The neurological symptoms, especially ataxia, stabilized after resection of tumor recurrence and concomitant chemoradiotherapy whereas anti-Hu-antibodies remained positive. Despite the unfavorable prognosis of paraneoplastic neurological disorders associated with onconeural antibodies, the patient achieved long-standing stabilization of neurological symptoms. We report the first patient with anti-Hu antibodies and paraneoplastic cerebellar degeneration associated with a spindle cell carcinoma of the head and neck. We recommend that evaluation of neurological symptoms in patients with this tumor entity should also include paraneoplastic syndromes as differential diagnoses and suggest early extensive screening for onconeural antibodies.

Paraneoplastic cerebellar degeneration is a rare dysfunction of the cerebellum associated with malignancy. Nevertheless, it is the most common paraneoplastic syndrome affecting the brain. A 50-year-old woman presented to the neurology outpatient department (OPD) with symptoms of cerebellar dysfunction since 4 months and complaints of a painless lump in the right breast and drooling from mouth since 1 month. Examination revealed classical signs of cerebellar dysfunction and a 5×5 cm lump in the right breast with a single right axillary lymph node. Serum anti-Yo antibody titre was strongly positive. The patient was referred to General Surgery OPD for opinion. After establishing the diagnosis of right breast carcinoma; she underwent a right modified radical mastectomy. She was referred to the oncologist for chemo/radiotherapy but because of poor performance status, only symptomatic treatment was pursued. Follow-up till now shows no improvement in the neurological dysfunction. © BMJ Publishing Group Limited [2018]. No commercial re-use. See rights and permissions. Published by BMJ.

Summary We review novel findings in paraneoplastic syndromes including the Lambert-Eaton myasthenic syndrome, and then focus on the novel disorders associated with antibodies against cell surface antigens, discussing the importance and caveats of antibody testing, and providing an algorithm for interpretation of results. In anti-NMDAR encephalitis 2 novel findings include the recognition of a characteristic EEG pattern (“extreme delta brush”) in 30% of patients and the demonstration of a fronto-temporo-occipital gradient of glucose metabolism that correlates with disease activity. In limbic encephalitis, antibodies to GABA(B) receptor are the most frequently detected in patients with small-cell lung cancer who are anti-Hu negative, and antibodies to mGluR5 distinctively associate with Hodgkin lymphoma (Ophelia syndrome). We also address the syndromes associated with “VGKC-complex antibodies,” a problematic term that groups well-characterized immune-mediated disorders (LGI1, Caspr2) with others that lack syndrome specificity, are less responsive to treatment, and for which the target antigens are unknown.

2015-11-15

We retrospectively analyzed three patients with pure motor neuronopathy followed for more than four years in our center. The patients presented a rapidly progressive lower motor neuron syndrome (LMNS) over the course of a few weeks leading to a severe functional impairment. The neurological symptoms preceded the diagnosis of a breast adenocarcinoma and a thymoma in the first two patients, one of them with anti-CV2/CRMP5 antibodies. Cancer was not detected in the third patient who had circulating anti-Hu antibodies. A final diagnosis of paraneoplastic syndrome was made after investigations for alternative causes of lower motor neuron syndrome. Early diagnosis, combined treatment of the underlying cancer, and immunomodulatory treatment led to neurological improvement of the disease in two out of the three cases in which the cancer was diagnosed. Cases of subacute LMNS with rapid progression may occur as an expression of a paraneoplastic neurological syndrome. Identification of these syndromes is important, as the treatment of underlying malignancy along with immunomodulatory treatment may result in a favorable long-term outcome of these potentially fatal diseases.

Paraneoplastic autoimmune movement disorders.

2017-11-01

To provide an overview of paraneoplastic autoimmune disorders presenting with various movement disorders. The spectrum of paraneoplastic autoimmune disorders has been expanding with the discovery of new antibodies against cell surface and intracellular antigens. Many of these paraneoplastic autoimmune disorders manifest as a form of movement disorder. With the discovery of new neuronal antibodies, an increasing number of idiopathic or neurodegenerative movement disorders are now being reclassified as immune-mediated movement disorders. These include anti-N-methyl-d-aspartate receptor (NMDAR) encephalitis which may present with orolingual facial dyskinesia and stereotyped movements, CRMP-5 IgG presenting with chorea, anti-Yo paraneoplastic cerebellar degeneration presenting with ataxia, anti-VGKC complex (Caspr2 antibodies) neuromyotonia, opsoclonus-myoclonus-ataxia syndrome, and muscle rigidity and episodic spasms (amphiphysin, glutamic acid decarboxylase, glycine receptor, GABA(A)-receptor associated protein antibodies) in stiff-person syndrome. Movement disorders may be a presentation for paraneoplastic autoimmune disorders. Recognition of these disorders and their common phenomenology is important because it may lead to the discovery of an occult malignancy. Copyright © 2017 Elsevier Ltd. All rights reserved.

[Autoantibodies in Paraneoplastic Neurological Syndrome].

Paraneoplastic neurological syndromes (PNS) are caused by immune responses against neuronal antigens expressed by the tumor. Based on the immunological pathomechanisms and responsiveness of treatments, onconeuronal antibodies are divided into two categories: 1) antibodies against neural intracellular antigens and 2) antibodies against neuronal surface or synaptic antigens. The recent discovery of onconeuronal antibodies have radically changed concepts of CNS autoimmunity, including PNS. The recognition of PNS provides a foundation for the early detection of underlying tumors and initiations of prompt treatments, which can result in substantial improvement. We here review the characteristic onconeuronal antibodies, including anti-Hu, anti-Ma2, and anti-N-methyl-D-aspartate receptor, and discuss the algorithm for the diagnosis of PNS.

Paraneoplastic disorders of eye movements

2011-01-01

Paraneoplastic syndromes affecting the brainstem and cerebellum are reported to cause a variety of abnormalities of eye movements. Recent studies have begun to account for the mechanisms underlying several syndromes, characterized by opsoclonus, slow, or dysmetric saccades, as well as downbeat nystagmus. We provide evidence that upbeat nystagmus in a patient with pancreatic cancer reflected a cerebellar-induced imbalance of otolithic pathways: she showed marked retropulsion, and her nystagmus was dependent on head position, being absent when supine, and suppressed with convergence. In addition to anti-Hu antibodies, we demonstrated antibodies to a novel neuronal cell surface antigen. Taken with other recent studies, our findings suggest that paraneoplastic syndromes arise due to antibodies against surface neuronal antigens, including receptors and channels. Abnormal eye movements in paraneoplastic syndromes offer insights into the pathogenesis of these disorders and the opportunity to test potential therapies, such as new drugs with effects on neuronal channels.

Paraneoplastic neuropathies.

2017-10-01

To review recent advances in paraneoplastic neuropathies with emphasis on their definition, different forms and therapeutic development. A strict definition of definite paraneoplastic neuropathies is necessary to avoid confusion. With carcinoma, seronegative sensory neuronopathies and neuronopathies and anti-Hu and anti-CV2/Contactin Response Mediator Protein 5 antibodies are the most frequent. With lymphomas, most neuropathies occur with monoclonal gammopathy including AL amyloidosis, Polyneuropathy-Organomegaly-Endocrinopathy-M component-Skin changes (POEMS) syndrome, type I cryoglobulinemia and antimyelin-associated glycoprotein (MAG) neuropathies and Waldenström's disease. Neuropathies improving with tumor treatment are occasional, occur with a variety of cancer and include motor neuron disease, chronic inflammatory demyelinating neuropathy and nerve vasculitis. If antibodies toward intracellular antigens are well characterized, it is not the case for antibodies toward cell membrane proteins. Contactin-associated protein-2 antibodies occur with neuromyotonia and thymoma with the Morvan's syndrome in addition to Netrin 1 receptor antibodies but may not be responsible for peripheral nerve hyperexcitability. The treatment of AL amyloidosis, POEMS syndrome, anti-MAG neuropathy and cryoglobulinemia is now relatively well established. It is not the case with onconeural antibodies for which the rarity of the disorders and a short therapeutic window are limiting factors for the development of clinical trials. A strict definition of paraneoplastic neuropathies helps their identification and is necessary to allow an early diagnosis of the underlying tumor.

Paraneoplastic neurological syndromes are rare autoimmune manifestations of malignancies associated with specific antibodies. Anti-Hu associated brainstem encephalitis, a well-described syndrome, usually presents subacutely with preferential involvement of the medulla. Anti-Hu antibodies target intraneuronal antigens and are therefore highly correlated with neurological syndromes when present concomitantly with a neoplasm. Reported is a case of anti-Hu brainstem encephalitis associated with a pancreatic neuroendocrine tumor (PNET) presenting with central hypoventilation. This is the first described case of brainstem encephalitis associated with a well-differentiated PNET as well as the first case of Anti-Hu antibodies associated with a PNET. There are no standardized protocols for the treatment of paraneoplastic brainstem encephalitis however, as in the present case, surgical resection and oncological treatment of the tumor is the first line treatment.

Recently, it was reported that remitting seronegative symmetrical synovitis with pitting edema (RS3PE) syndrome could be complicated with solid tumors. In a retrospective, multicenter study between October, 2003 and September, 2010, we investigated the characteristics of patients with paraneoplastic RS3PE syndrome who fulfilled following criteria: (1) bilateral pitting edema of hands or feet or both, (2) sudden onset of polyarthritis, and (3) age >50 years, (4) seronegativity for rheumatoid factor (RF). A total of 33 cases fulfilled the above criteria. Eight patients (seven men and one woman) developed cancer within 2 years of RS3PE syndrome onset. There was no significant difference between the neoplastic and nonneoplastic groups in the proportions of patients with fever, symmetrical polyarthritis, pitting edema, and good response to corticosteroids. Serum matrix metalloproteinase 3 (MMP-3) level (median 437.3 ng/ml) in the paraneoplastic RS3PE patients was significantly higher than that in patients without neoplasia (median 114.7 ng/ml) (p < 0.05). We found that high serum MMP-3 is characteristic of patients with paraneoplastic RS3PE syndrome.

While paraneoplastic syndromes in patients with malignant and metastasizing tumors are common, they are rarely associated with skin tumors showing predominantly local growth patterns. This case report relates to a patient with giant condyloma acuminatum, also called Buschke-Löwenstein tumor, with paraneoplastic hypercalcemia, who was successfully treated with conservative treatment. The patient in question is a 48-year-old German man with a giant periscrotal tumor. Before and during the therapy, two episodes of symptomatic hypercalcemia occurred, which were successfully treated by bisphosphonates, intravenous fluids and diuretics. No evidence of lytic bone affection was found. Paraneoplastic hypercalcemia may occur in patients who have a Buschke-Löwenstein tumor. For patients, where surgery is not an option, established medical therapies like bisphosphonates may be useful in addition to diuretics and infusions.

Experts in the autoimmune paraneoplastic field recommend autoantibody testing as "panels" to improve the poor sensitivity of individual autoantibodies in detecting paraneoplastic neurological syndromes (PNS). The sensitivity of those panels was not reported to date in a fashion devoid of incorporation bias. We aimed to assess the collective sensitivity and specificity of one of the commonly used panels in detecting PNS. A single-centered retrospective cohort of all patients tested for paraneoplastic evaluation panel (PAVAL; test ID: 83380) over one year for the suspicion of PNS. Case adjudication was based on newly proposed diagnostic criteria in line with previously published literature, but modified to exclude serological status to avoid incorporation bias. Measures of diagnostic accuracy were subsequently calculated. Cases that failed to show association with malignancy within the follow-up time studied, reflecting a possibly pure autoimmune process was considered paraneoplastic-like syndromes. Out of 321 patients tested, 51 patients tested positive. Thirty-two patients met diagnostic criteria for paraneoplastic/paraneoplastic-like syndromes. The calculated collective sensitivity was 34% (95% CI: 17-53), specificity was 86% (95% CI: 81-90), Youden's index 0.2 and a positive clinical utility index 0.07 suggesting poor utility for case-detection. This is the first reported diagnostic accuracy measures of paraneoplastic panels without incorporation bias. Despite recommended panel testing to improve detection of PNS, sensitivity remains low with poor utility for case-detection. The high-calculated specificity suggests a possible role in confirming the condition in difficult cases suspicious for PNS, when enough supportive evidence is lacking on ancillary testing.

The skin often signals systemic changes. Some neoplastic diseases that affect internal organs may trigger several cutaneous manifestations. Although these dermatoses are relatively unusual, the recognition of some typical paraneoplastic dermatoses may lead to the early diagnosis of a neoplasm and determine a better prognosis. In this review article, we discuss the paraneoplastic cutaneous manifestations strongly associated with neoplasms, which include acanthosis nigricans maligna, tripe palms, erythema gyratum repens, Bazex syndrome, acquired hypertrichosis lanuginosa, necrolytic migratory erythema, Leser-Trélat sign and paraneoplastic pemphigus.

A 52-year-old female patient was admitted to hospital because of progressive thrombosis despite therapeutic anticoagulation as well as leukocytosis with eosinophilia and thrombocytopenia. On examination, the patient presented with dyspnea and swelling oft her left leg and arm. The laboratory findings revealed leukocytosis (31,000/microl) with eosinophilia (54%), thrombocytopenia (58,000/microl), together with an increased C-reactive protein of 247 mg/dl (reference range < 5 mg/dl). Initial computed tomography scans showed pulmonary embolism and a slightly enlarged left inguinal lymph node. Histological examination of the lymph node biopsy revealed in part an epitheloid and spindle cell-like tumorous lesion with slightly increased tissue eosinophilia consistent with an inflammatory myofibroblastic tumor (IMT). Resection of the left inguinal lymph node resulted in an immediate regression of the paraneoplastic eosinophilia and thrombocytopenia. Anti-inflammatory medication with ibuprofen was subsequently initiated. Imaging and clinical examination at 3 months after discharge revealed no relapse and no signs of a paraneoplastic syndrome. The IMT is a rare soft-tissue tumor of intermediate dignity with a low tendency to metastasize. It is consistently accompanied by paraneoplastic syndromes. Therapy of choice is complete resection of the tumor. In nonresectable cases, corticosteroids and nonsteroidal antirheumatics have been shown to be effective. Because of the variable clinical course ranging from spontaneous regression to metastasis, IMTs might be separated into different entities (autoimmune, inflammatory, neoplastic subtype) which thus far cannot be classified on a histopathologic basis. A clinical assessment of the dignity is therefore important until further subclassifications of this rare disease become available.

Paraneoplastic brain stem encephalitis.

PubMed

Blaes, Franz

2013-04-01

Paraneoplastic brain stem encephalitis can occur as an isolated clinical syndrome or, more often, may be part of a more widespread encephalitis. Different antineuronal autoantibodies, such as anti-Hu, anti-Ri, and anti-Ma2 can be associated with the syndrome, and the most frequent tumors are lung and testicular cancer. Anti-Hu-associated brain stem encephalitis does not normally respond to immunotherapy; the syndrome may stabilize under tumor treatment. Brain stem encephalitis with anti-Ma2 often improves after immunotherapy and/or tumor therapy, whereas only a minority of anti-Ri positive patients respond to immunosuppressants or tumor treatment. The Opsoclonus-myoclonus syndrome (OMS) in children, almost exclusively associated with neuroblastoma, shows a good response to steroids, ACTH, and rituximab, some patients do respond to intravenous immunoglobulins or cyclophosphamide. In adults, OMS is mainly associated with small cell lung cancer or gynecological tumors and only a small part of the patients show improvement after immunotherapy. Earlier diagnosis and treatment seem to be one major problem to improve the prognosis of both, paraneoplastic brain stem encephalitis, and OMS.

Recent studies suggest that paraneoplastic pemphigus (PNP) is a heterogeneous autoimmune syndrome involving several internal organs and that the pathophysiological mechanisms mediating cutaneous, mucosal, and internal lesions are not limited to autoantibodies targeting adhesion molecules. To classify the diverse mucocutaneous and respiratory presentations of PNP and characterize the effectors of humoral and cellular autoimmunity mediating epithelial tissue damage. We examined 3 patients manifesting the lichen planus pemphigoideslike subtype of PNP. A combination of standard immunohistochemical techniques, enzyme-linked immunosorbent assay with desmoglein (DSG) baculoproteins, and an immunoprecipitation assay were used to characterize effectors of humoral and cellular autoimmunity in patients with PNP and in neonatal wild-type and DSG3-knockout mice with PNP phenotype induced by passive transfer of patients' IgGs. In addition to the known "PNP antigenic complex," epithelial targets recognized by PNP antibodies included 240-, 150-, 130-, 95-, 80-, 70-, 66-, and 40/42-kd proteins but excluded DSG1 and DSG3. In addition to skin and the epithelium lining upper digestive and respiratory tract mucosa, deposits of autoantibodies were found in kidney, urinary bladder, and smooth as well as striated muscle. Autoreactive cellular cytotoxicity was mediated by CD8(+) cytotoxic T lymphocytes, CD56(+) natural killer cells, and CD68(+) monocytes/macrophages. Inducible nitric oxide synthase was visualized both in activated effectors of cellular cytotoxicity and their targets. Keratin 14-positive basal epithelial cells sloughed from the large airways and obstructed small airways. The paraneoplastic disease of epithelial adhesion known as PNP in fact represents only 1 manifestation of a heterogeneous autoimmune syndrome in which patients, in addition to small airway occlusion and deposition of autoantibodies in different organs, may display a spectrum of at least 5 different clinical

Analyse the clinical profile, associated tumour types, and response to treatment of paraneoplastic neurological syndromes associated with antibodies against Ma proteins. A retrospective study of patients with antibodies against Ma proteins identified in a neuroimmunology laboratory of reference. Of the 32 patients identified, 20 showed reactivity against Ma2 only (anti-Ma2 antibodies), 11 against Ma1 and Ma2 (anti-Ma antibodies), and 1 with reactivity against Ma1 only (anti-Ma1 antibodies). The most common clinical presentations were limbic encephalopathy, diencephalic dysfunction, or brainstem encephalopathy, frequently appearing as a combination of these features. Three patients had isolated cerebellar dysfunction with anti-Ma antibodies, and 2 exhibited peripheral nervous system syndrome with anti-Ma2 antibodies. Testicular tumours were the most common neoplasms (40%) in the anti-Ma2 cases. In the group associated with anti-Ma1 antibodies, the most common were lung tumours (36%), followed by testicular tumours. All idiopathic cases were reactive to Ma2. The clinical outcome was significantly better in the anti-Ma2 group. The patient with anti-Ma1 presented with limbic encephalitis and brainstem dysfunction associated with lymphoepithelioma of the bladder. Specifically determining the different reactivities of anti-Ma protein antibodies in order to differentiate between Ma1 and Ma2 antibodies is important because anti-Ma2-associated paraneoplastic syndromes have a better outcome. Lastly, this study is the first to confirm that there may be cases that react exclusively to antibodies against Ma1. Copyright © 2016 Sociedad Española de Neurología.

A 61-year-old woman who had smoked for 41 years developed subacute dizziness, ataxic gait, opsoclonus, and right visual impairment. She had right optic disc swelling and optic nerve gadolinium enhancement on magnetic resonance imaging. She had small-cell lung cancer (SCLC), with CV2/collapsin response mediator protein (CRMP) 5 and HuD antibodies in her serum and cerebrospinal fluid. She was diagnosed with paraneoplastic optic neuropathy (PON) accompanied by paraneoplastic opsoclonus-ataxia syndrome. Her symptoms improved after removing the SCLC. Classical PON is rare in Japan. We recommend assaying for CV2/CRMP5 antibodies and searching for cancer in elderly patients with subacute painless visual impairment.

Paraneoplastic pemphigus (PNP), a clinically and immunopathologically distinct mucocutaneous blistering dermatosis, is a severe form of autoimmune multiorgan syndrome generally associated with poor therapeutic outcome and high mortality. This IgG-mediated disease is initiated by an obvious or occult lymphoproliferative disorder in most cases. Clinically severe mucositis, and polymorphic blistering skin eruptions, and histologically acantholysis, keratinocyte necrosis and interface dermatitis are its hallmark features. A 58-year-old female presented with recurrent, severe, recalcitrant stomatitis and widespread erosions/blistering lesions of one-year duration. Treatment with repeated courses of systemic corticosteroids at a peripheral center would provide temporary relief. She also had fever, productive cough, odynophagia and poor oral intake, herpes zoster ophthalmicus, pain in the abdomen, and watery diarrhea. An array of investigations revealed chronic lymphocytic leukemia (CLL), mediastinal and para-aortic lymphadenopathy, bronchiolitis obliterans, and vertebral osteoporosis/fractures. With the diagnosis of CLL-associated PNP she was managed with dexamethasone-cyclophosphamide pulse (DCP) therapy for 3 cycles initially, followed by COP regimen (cyclophosphamide, vincristine, and prednisolone) for 5 cycles. Remission is being maintained with chlorambucil and prednisolone pulse therapy once in 3 weeks with complete resolution of skin lesions and adequate control of CLL. PMID:23316398

Paraneoplastic syndromes are generally defined as clinical disorders associated with malignant diseases, and hypocalcemia associated with cancer is a rare condition. A woman in her 60s was referred to our hospital for the further examination of massive ascites due to carcinoma of unknown primary origin. She complained of numbness around her lips, and marked hypocalcemia of 5.0 mg/dL was noted. After two courses of chemotherapy, computed tomography showed a decrease in the ascites, and her serum calcium level increased. Although hypocalcemia is a very rare condition in patients with gastric cancer, serum calcium values should be evaluated when neurological symptoms are observed.

A 48-year-old man with autoimmune Addison disease developed the following paraneoplastic neurologic syndromes (PNNS): limbic encephalitis, opsoclonus/myoclonus, and sensorimotor and autonomic neuropathies. An anterior mediastinal mass detected on a chest computed tomographic scan was found on resection to be a noninvasive lymphocytic thymoma. The PNNS went into remission 1 year after the thymectomy. This is the first case of thymoma associated with autoimmune Addison disease and PNNS to be described in the literature.

Paraneoplastic syndromes (PS) comprise a variety of clinical symptoms and diseases associated with underlying malignancy. Differentiation towards benign autoimmune diseases is necessary due to different therapeutic options. This diagnostic challenge includes cost- and time-consuming methods and is not successful in many cases. The aim of this study was the evaluation of [(18)F]fluorodeoxyglucose positron emission tomography ([(18)F]FDG-PET) for detecting or ruling out malignancy in these patients. In this retrospective work-up a total of 30 patients with suspected PS (m:f = 17:13, mean age 55, range 22-76 years) were examined with [(18)F]FDG-PET between 1996 and 2001. Diagnoses were erythrodermia, cerebellar degeneration, dermatomyositis, polyneuropathia and others. PET scans were compared to histopathological (n=14), radiological and follow up data (mean follow up 3.6 years, range 1-6 years). In 7 out of 30 patients (23%) an underlying malignancy was detected. Six out of 7 malignant neoplasms showed a distinctly increased glucose consumption. One benign neoplasm caused increased tracer uptake, another PET positive patient refused biopsy and showed no growth of a malignant tumour during clinical follow up of 28 months. The remaining 21 patients without suspicious glucose consumption did not demonstrate a malignancy in other diagnostic modalities or during subsequent clinical follow-up. [(18)F]FDG-PET seems to be a useful tool in the diagnostic work-up of patients with suspected paraneoplastic syndrome.

Tumour-induced osteomalacia: An emergent paraneoplastic syndrome.

PubMed

Alonso, Guillermo; Varsavsky, Mariela

2016-04-01

Endocrine paraneoplastic syndromes are distant manifestations of some tumours. An uncommon but increasingly reported form is tumour-induced osteomalacia, a hypophosphatemic disorder associated to fibroblast growth factor 23 (FGF-23) secretion by tumours. The main biochemical manifestations of this disorder include hypophosphatemia, inappropriately low or normal tubular reabsorption of phosphate, low serum calcitriol levels, increased serum alkaline phosphatase levels, and elevated or normal serum FGF-23 levels. These tumours, usually small, benign, slow growing and difficult to discover, are mainly localized in soft tissues of the limbs. Histologically, phosphaturic mesenchymal tumours of the mixed connective tissue type are most common. Various imaging techniques have been suggested with variable results. Treatment of choice is total surgical resection of the tumour. Medical treatment includes oral phosphorus and calcitriol supplements, octreotide, cinacalcet, and monoclonal antibodies.

The patient was a 69-year-old male who had started experiencing acute-onset pain in both shoulder joints and edema of both hands and feet. His symptoms progressively worsened within 1 month. Laboratory data indicated elevated CRP and erythrocyte sedimentation rate despite the normal range of antinuclear antibodies and rheumatoid factor and normal organ function. Furthermore, imaging data of the hand indicated synovitis without bone erosions. Meanwhile, chest CT revealed a lung tumor, leading to a diagnosis of primary lung adenocarcinoma with EGFR mutation (cT2aN3M0, stage IIIB). Based on these findings, he was diagnosed as suffering from paraneoplastic remitting seronegative symmetrical synovitis with pitting edema (RS3PE) syndrome. Thereafter, his symptoms disappeared as the tumor size was rapidly decreased by gefitinib therapy for lung adenocarcinoma. Currently, RS3PE syndrome can be classified as a vascular endothelial growth factor (VEGF)-associated disorder. Given that his symptoms improved by chemotherapy, the present case further supported the possible hypothesis that paraneoplastic RS3PE syndrome might be caused by tumor-induced VEGF. Therefore, the present case suggested that the symptoms of acute-onset joint pain accompanied by pitting edema in elderly patients should be considered suspicious for a malignant tumor, thereby warranting a detailed full-body examination.

Castleman's disease is a rare autoimmune disorder with varied clinical presentations. Castleman's commonly involves mediastinum and hence it is thoracic in most of the reported cases. Paraneoplastic pemphigus (PNP) and myasthenia gravis can be associated with multicentric Castleman's disease. Its association with HIV, Kaposi sarcoma, and lymphoma is also well known. We report a rare combination of unicentric, extrathoracic Castleman's disease with PNP and myasthenia gravis. PMID:25071278

Paraneoplastic cerebellar degeneration (PCD) is a rare paraneoplastic syndrome, occurring in <1% of breast cancers. We describe a 32-year-old female presenting with ataxia subsequently diagnosed with poorly differentiated breast cancer. She was serum anti-Yo antibody positive, with estrogen/progesterone receptor negative and HER2/neu receptor positive breast cancer. Neurological symptoms progressed despite modified radical mastectomy, supraclavicular lymphadenectomy, intravenous immunoglobulin, corticosteroids, transtuzumab, and combination chemotherapy. We performed a literature search, which found a possible association between anti-Yo positive PCD and HER2/neu-expressing breast cancer.

Sera from 23 patients with paraneoplastic disease of the central nervous system (PNS) were examined for the presence of anti-neuronal (anti-Hu, anti-Yo/PCA) and anti-Ri) and systemic auto-antibodies, including antibodies against DNA, centromeres, nRNP, Sm antigen, Scl-70, Ro(SS-A), La(SS-B), mitochondria, thyroid antigens, parietal calls, brush border antigen and rheumatoid factor. As controls, sera from 33 patients with small cell lung cancer, 33 with ovarian cancer and 7 with breast cancer and from 107 aged-matched healthy persons were used. Systemic auto-antibodies were found in 52% of patients with paraneoplastic neurological syndromes compared with only 16% (P = 0.001) in the control group with cancer only and 15% in the group of healthy controls. The relatively high percentage of systemic auto-antibodies in patients with PNS indicates that there is a genetic susceptibility to the development of auto-immune phenomena. This may provide an explanation for the relatively rare occurrence of PNS in patients with cancer.

[Stroke and Cancer: Are Cryptogenic Strokes a Paraneoplastic Syndrome?].

PubMed

Eschle, Daniel

2015-07-22

Cancer is an independent risk factor for ischemic stroke, and stroke can precede tumour diagnosis by many months. A paraneoplastic hypercoagulability has been implicated. Overall, cancer is a rare cause, but should be suspected in cases of cryptogenic stroke. In patients with cryptogenic stroke, two criteria – ischemic lesions in multiple vascular territories and D-dimer values >2,15 µg/ml – predict cancer with 100% specificity according to one relevant study. An adenocarcinoma at an advanced stage is identified in many cases, the risk of stroke-recurrence is high. There is a lack of evidence-based recommendations regarding secondary prevention in these cases. In analogy to the guidelines for venous thromboembolism in cancer patients, low molecular weight heparins might be more efficient compared to other anti-clotting agents.

Clonazepam responsive opsoclonus myoclonus syndrome: additional evidence in favour of fastigial nucleus disinhibition hypothesis?

2010-05-01

Opsoclonus myoclonus syndrome is a rare paraneoplastic syndrome seen in 50% of children with neuroblastoma. Neural generator of opsoclonus and myoclonus is not known but evidences suggest the role of fastigial nucleus disinhibition from the loss of function of inhibitory (GABAergic) Purkinje cells in the cerebellum. We present a child with paraneoplastic opsoclonus myoclonus syndrome who responded well to clonazepam. Response to clonazepam is an evidence for the involvement of GABAergic neural circuits in the genesis of opsoclonus myoclonus syndrome and is in agreement with fastigial nucleus disinhibition hypothesis.

A paraneoplastic manifestation of metastatic breast cancer responding to endocrine therapy: a case report

2008-01-01

Background Many cancers are known to be associated with paraneoplastic syndromes. These syndromes are usually treated by chemotherapy with or without immunosupression but they often respond poorly. There are no published reviews on response to endocrine treatment. Case presentation We report a case of a patient presenting with papillitis, myositis and sensory peripheral neuropathy 18 months before a diagnosis of metastatic oestrogen receptor positive breast cancer was confirmed. The patient was treated with anastrozole which led not only to a decrease of her tumour burden but also to an improvement in her biochemical markers and amelioration of her clinical symptoms. Conclusion This case is an example of breast cancer presenting with paraneoplastic manifestations. It took several months to establish the cause of symptoms in this patient thus illustrating the need for physicians to maintain a high index of suspicion for paraneoplastic syndromes in women presenting with unusual neurological symptoms with no obvious cause. It is a unique case as it illustrates how treatment with an aromatase inhibitor leading to cancer regression can result in an improvement in the paraneoplastic symptoms. PMID:19087318

Merkel cell carcinoma is a rare cutaneous, aggressive tumor. Although it shares many neuroendocrine features with small cell lung carcinoma, it has only occasionally been reported with paraneoplastic neurological syndromes. A healthy 67-year-old man developed acute ataxia, vertigo, and nausea. Subsequently he also developed dysarthria, diplopia, xerostomia, fatigability and progressive anorexia. He underwent a full diagnostic workup and was found to have a high titer of voltage-gated calcium channel antibodies in serum and cerebrospinal fluid, neurophysiological findings compatible with Lambert-Eaton myasthenia and neurological signs compatible with cerebellar degeneration. A positron emission tomography study revealed a hypermetabolic lesion in the axilla, subsequently biopsied and consistent with Merkel cell carcinoma. In most previous reports, neurological symptoms preceded the Merkel cell carcinoma diagnosis, and the primary localization was in lymph nodes. This tumor should be considered in patients with paraneoplastic syndrome, and particularly Lambert-Eaton myasthenia after exclusion of small cell lung carcinoma.

Movement disorders in paraneoplastic and autoimmune disease

PubMed Central

Panzer, Jessica; Dalmau, Josep

2013-01-01

Purpose of review The most relevant advances in immune-mediated movement disorders are described, with emphasis on the clinical–immunological associations, novel antigens, and treatment. Recent findings Many movement disorders previously considered idiopathic or degenerative are now recognized as immune-mediated. Some disorders are paraneoplastic, such as anti-CRMP5-associated chorea, anti-Ma2 hypokinesis and rigidity, anti-Yo cerebellar ataxia and tremor, and anti-Hu ataxia and pesudoathetosis. Other disorders such as Sydenham's chorea, or chorea related to systemic lupus erythematosus and antiphospholipid syndrome occur in association with multiple antibodies, are not paraneoplastic, and are triggered by molecular mimicry or unknown mechanisms. Recent studies have revealed a new category of disorders that can be paraneoplastic or not, and associate with antibodies against cell-surface or synaptic proteins. They include anti-N-methyl-d-aspartate receptor (anti-NMDAR) encephalitis, which may cause dyskinesias, chorea, ballismus or dystonia (NMDAR antibodies), the spectrum of Stiff-person syndrome/muscle rigidity (glutamic acid decarboxylase, amphiphysin, GABAA-receptor-associated protein, or glycine receptor antibodies), neuromyotonia (Caspr2 antibodies), and opsoclonus–myoclonus–ataxia (unknown antigens). Summary Neurologists should be aware that many movement disorders are immune-mediated. Recognition of these disorders is important because it may lead to the diagnosis of an occult cancer, and a substantial number of patients, mainly those with antibodies to cell-surface or synaptic proteins, respond to immunotherapy.

A 27-month-old girl presented with chest pain. Further evaluation confirmed posterior mediastinal neuroblastoma with bone marrow infiltration, which was treated with a combination of chemotherapy and surgery. Four months after completing treatment, she presented with myoclonus and weakness of her right arm. The myoclonus eventually subsided but her right arm weakness progressed to a right hemiplegia. High titers of antineuronal nuclear antibodies identified as anti-Hu were found in both serum and cerebrospinal fluid. One month later she presented with a relapse of her original tumor, from which she died. Identification of anti-Hu antineuronal nuclear antibodies in this neuroblastoma-associated paraneoplastic syndrome supports the hypothesis that the syndrome is due to autoimmune disease.

Abstract Cutaneous vasculitis may be associated with malignancies, and may behave as a paraneoplastic syndrome. This association has been reported in a variable proportion of patients depending on population selection. We conducted the current study to assess the frequency, clinical features, treatment, and outcome of paraneoplastic vasculitis in a large unselected series of 766 patients with cutaneous vasculitis diagnosed at a single university hospital. Sixteen patients (10 men and 6 women; mean age ± standard deviation, 67.94 ± 14.20 yr; range, 40–85 yr) presenting with cutaneous vasculitis were ultimately diagnosed as having an underlying malignancy. They constituted 3.80% of the 421 adult patients. There were 9 hematologic and 7 solid underlying malignancies. Skin lesions were the initial clinical presentation in all of them, and the median interval from the onset of cutaneous vasculitis to the diagnosis of the malignancy was 17 days (range, 8–50 d). The most frequent skin lesions were palpable purpura (15 patients). Other clinical manifestations included constitutional syndrome (10 patients) and arthralgia and/or arthritis (4 cases). Hematologic cytopenias (11 cases) as well as immature peripheral blood cells (6 cases) were frequently observed in the full blood cell count, especially in those with vasculitis associated with hematologic malignancies. Specific treatment for vasculitis was prescribed in 10 patients; nonsteroidal antiinflammatory drugs (4 patients), corticosteroids (3 patients), chloroquine (1 patient), antihistamines (1 patient), and cyclophosphamide (1 patient). Ten patients died due to the malignancy and 6 patients recovered following malignancy therapy. Patients with paraneoplastic vasculitis were older, more frequently had constitutional syndrome, and less frequently had organ damage due to the vasculitis than the remaining patients with cutaneous vasculitis. In summary, cutaneous paraneoplastic vasculitis is an entity not uncommonly

In clinical practice, the term "paraneoplastic itch" is used to describe itch in patients with cancer. Patients with hematological or solid tumor malignancies can be affected. In general, paraneoplastic itch is considered a rare disorder. However, paraneoplastic itch in hematological malignancies such as polycythemia vera and lymphoma are relatively frequent while other forms of paraneoplastic itch are in fact extremely rare. The true frequency of this symptom is unclear, epidemiological data in this field are limited. Itch in malignant disease may additionally impair patients' quality of life. A population-based cohort study showed that chronic itch without concomitant skin changes is a risk factor for having undiagnosed hematologic and bile duct malignancies. Paraneoplastic itch is rather resistant to treatment. In 2012, an interdisciplinary interest group of physicians and researchers was founded, aiming to generate a clear definition of paraneoplastic itch. In this paper we briefly review the current knowledge and aim to define what can be summarized under the term "paraneoplastic itch".

Paraneoplastic Cushing's syndrome is a rare cause of endogenous hypercortisolism attributable to ectopic ACTH secretion by non-pituitary tumors. Imaging and biochemical results are often inconclusive and differential diagnosis with Cushing's disease can then be challenging. Moreover, these tumors may be occult and difficult to find and thus the need of new imaging tools such as (18)FDG-PET scan and (18)DOPA-PET scan. We report a 50-year-old man who presented with very aggressive clinical features related to Cushing's syndrome. Biological work-up confirmed the hypercortisolism and was consistent with an ectopic ACTH secretion. Conventional localization techniques failed to show any tumor and bilateral adrenalectomy was performed because of life-threatening complications. Two years later, thoracic computed tomography reveals an 11 mm mass in the left lower pulmonary lobe, (18)FDG-PET scan found a non-specific mild hypermetabolism of the lung nodule, and the (18)DOPA-PET scan confirmed the high uptake of this nodule suggesting an endocrine carcinoma. Histology confirmed a typical carcinoid tumor. The tumor cells stained positive for ACTH, CD56, chromogranin and synaptophysin. This case illustrates the dilemma between the need for morphological diagnosis of the ectopic ACTH source and control of the life-threatening hypercortisolism. (18)FDG-PET scan and (18)DOPA-PET scan should be considered early as a secondary diagnostic tool when conventional imagery fails to show any tumor.

Paraneoplastic neurological syndromes are rare, and although they are frequently associated with gynecological malignancies, cervical cancer is a rare cause. The symptoms of anti-Ma2 encephalitis are diverse and often present prior to the diagnosis of malignancy. We report a case of a 37-year-old woman with a history of cervical cancer presenting with unexplained weight gain and vertical supranuclear gaze palsy. Magnetic resonance imaging of the brain revealed lesions within the bilateral hypothalami and midbrain. Anti-Ma2 antibodies were eventually found in the serum, prompting a search for malignancy. Recurrent metastatic cervical cancer was found in the retroperitoneal lymph nodes. This is the first report of cervical cancer in association with anti-Ma2 encephalitis, and highlights the need for a high degree of suspicion in patients with a cancer history presenting with neurological symptoms. The symptoms associated with anti-Ma2 encephalitis are diverse and typically precede the diagnosis of cancer in patients, and should trigger a search for an underlying malignancy.

Objective: To determine the frequency and range of paraneoplastic neurologic disorders (PNDs) and neuronal antibodies in small cell lung carcinoma (SCLC). Methods: Two hundred sixty-four consecutive patients with biopsy-proven SCLC were recruited at the time of tumor diagnosis. All patients underwent full neurologic examination. Serum samples were taken prior to chemotherapy and analyzed for 15 neuronal antibodies. Thirty-eight healthy controls were analyzed in parallel. Results: PNDs were quite prevalent (n = 24, 9.4%), most frequently Lambert-Eaton myasthenic syndrome (3.8%), sensory neuronopathy (1.9%), and limbic encephalitis (1.5%). Eighty-seven percent of all patients with PNDs had antibodies to SOX2 (62.5%), HuD (41.7%), or P/Q VGCC (50%), irrespective of their syndrome. Other neuronal antibodies were found at lower frequencies (GABAb receptor [12.5%] and N-type VGCC [20.8%]) or very rarely (GAD65, amphiphysin, Ri, CRMP5, Ma2, Yo, VGKC complex, CASPR2, LGI1, and NMDA receptor [all <5%]). Conclusions: The spectrum of PNDs is broader and the frequency is higher than previously appreciated, and selected antibody tests (SOX2, HuD, VGCC) can help determine the presence of an SCLC.

Paraneoplastic hypercalcemia.

PubMed

Bergman, Philip J

2012-11-01

Paraneoplastic syndromes (PNSs) are neoplasm-associated alterations in bodily structure or function or both that occur distant to the tumor. They are an extremely diverse group of clinical aberrations that are associated with the noninvasive actions of the tumor. In many situations, the PNS parallels the underlying malignancy, and therefore, successful treatment of the tumor leads to disappearance of the PNS. Alternatively, recurrence of the PNS after successful treatment signals recurrence of the tumor, and the return of the PNS often significantly precedes the detectable recurrence of the tumor. This is often the case with paraneoplastic hypercalcemia, often referred to as hypercalcemia of malignancy (HM). The most common cause of hypercalcemia in dogs is cancer. Neoplasia is diagnosed in approximately two-thirds of dogs with hypercalcemia vs. approximately one-third in cats. A variety of tumors have been associated with HM. Lymphoma is the most common cause of HM, and the most common anatomical site for dogs with lymphoma-associated HM is the cranial mediastinum. Other tumors associated with HM in dogs and cats include anal sac apocrine gland adenocarcinoma, thyroid carcinoma, multiple myeloma, bone tumors, thymoma, squamous cell carcinoma, mammary gland carcinoma/adenocarcinoma, melanoma, primary lung tumors, chronic lymphocytic leukemia, renal angiomyxoma, and parathyroid gland tumors. As HM is a potential medical emergency, the primary goal in cases of HM is the elucidation of the underlying cause and thereby instituting the appropriate specific therapy.

Paraneoplastic myasthenia gravis: immunological and clinical aspects.

PubMed

Skeie, G O; Romi, F

2008-10-01

Paraneoplastic myasthenia gravis (MG) is accompanied by a neoplasm, usually thymoma. In patients with thymoma and a specific genetic make-up, the paraneoplastic immune response develops further in thymic remnant or peripheral lymphatic tissue. Paraneoplastic MG and late-onset MG (age >or= 50 years) share a similar immunological profile with high titin and ryanodine receptor (RyR) antibody prevalence. This profile is the most important predictor of clinical outcome in paraneoplastic MG. The presence of a thymoma per se does not cause more severe MG. MG severity is linked to the patient's immunological profile. Paraneoplastic MG causes a distinctive non-limb symptom profile at MG onset, characterized by bulbar, ocular, neck, and respiratory symptoms. When the diagnosis of paraneoplastic MG is established, the neoplasm should be removed surgically. Pre-thymectomy plasmapheresis or iv-IgG should be considered in these patients to minimize post-thymectomy MG exacerbation risk. Paraneoplastic MG usually continues after thymectomy. The pharmacological treatment of paraneoplastic MG does not differ from non-paraneoplastic MG, except for tacrolimus that should be considered in difficult cases. Tacrolimus is an immunosuppressant acting specifically in RyR antibody positive patients through enhancing RyR-related sarcoplasmic calcium release that in theory might be blocked by RyR antibodies, causing symptomatic relief in paraneoplastic MG.

Anti-Ma2 Paraneoplastic Encephalitis in Association with Recurrent Cervical Cancer

Background Paraneoplastic neurological syndromes are rare, and although they are frequently associated with gynecological malignancies, cervical cancer is a rare cause. The symptoms of anti-Ma2 encephalitis are diverse and often present prior to the diagnosis of malignancy. Case Report We report a case of a 37-year-old woman with a history of cervical cancer presenting with unexplained weight gain and vertical supranuclear gaze palsy. Magnetic resonance imaging of the brain revealed lesions within the bilateral hypothalami and midbrain. Anti-Ma2 antibodies were eventually found in the serum, prompting a search for malignancy. Recurrent metastatic cervical cancer was found in the retroperitoneal lymph nodes. Conclusions This is the first report of cervical cancer in association with anti-Ma2 encephalitis, and highlights the need for a high degree of suspicion in patients with a cancer history presenting with neurological symptoms. The symptoms associated with anti-Ma2 encephalitis are diverse and typically precede the diagnosis of cancer in patients, and should trigger a search for an underlying malignancy. PMID:25045381

Paraneoplastic necrotizing myopathy is a rare disorder, described as a proximal, symmetrical, and rapidly progressing myopathy that is manifested as a paraneoplastic syndrome. Diagnosis is established via histological examination of the muscle biopsy. We present the case of a 53-year-old woman, born in Guinea-Bissau, with a history of locally advanced breast cancer, diagnosed ten months previously. The patient had experienced a progressively proximal muscle weakness of the lower extremities, which led to a total inability to walk. Upon neurological examination, the patient showed muscle weakness and atrophy in both proximal lower extremities without myalgia. Muscle strength was graded according to the Medical Research Council Scale as 2 out of 5 in the bilateral iliopsoas muscle, and 4 out of 5 in the bilateral quadriceps femoris. The deep-tendon reflexes were hypoactive. The laboratory examination showed increased values of serum creatinine kinase and myoglobin. An electromyogram showed an incomplete interference pattern during voluntary contraction in the iliopsoas and quadriceps femoris. The motor nerve conduction was 44.1 m/s and 44.3 m/s in the right and left tibial nerves, respectively, and 46.5 m/s and 46.1 m/s in the right and left peroneal nerves, respectively. The sensory motor nerve conductions and the compound motor action potential amplitudes were normal. These findings, despite not being specific, suggested a myopathy. Consequently, a muscle biopsy was performed. A biopsy specimen showed myopathic changes that were characteristic of a necrotizing myopathy. Treatment for this syndrome consists of controlling the tumor, and providing corticoid therapy. This led to the partial remission of the neurological manifestations.

MSA Mimic? Rare Occurrence of Anti-Hu Autonomic Failure and Thymoma in a Patient with Parkinsonism: Case Report and Literature Review

Thymoma is a tumor originating from thymic gland, frequently manifesting with paraneoplastic neurological disorders. Its association with paraneoplastic dysautonomia is relatively uncommon. Here, we describe the challenging case of a 71 year-old female who developed subacute autonomic failure with digestive pseudo-obstruction, dysphagia, urinary tract dysfunction and orthostatic hypotension complicating an underlying extrapyramidal syndrome that had started 3 months before hospital admission. Autonomic symptoms had 2-month course and acutely worsened just before and during hospitalization. Combination of severe dysautonomia and parkinsonism mimicked rapidly progressing multiple system atrophy. However, diagnostic exams showed thymic tumor with positive anti-Hu antibodies on both serum and cerebrospinal fluid. Complete response of dysautonomia to immunoglobulins followed by thymectomy confirmed the diagnosis of anti-Hu-related paraneoplastic neurological syndrome. With regards to extrapyramidal symptoms, despite previous descriptions of paraneoplastic parkinsonism caused by other antineuronal antibodies, in our case no relation between anti-Hu and parkinsonism could be identified. A literature review of published reports describing anti-Hu positivity in thymic neoplasms highlighted that a definite autonomic disease due to anti-Hu antibodies is extremely rare in patients with thymoma but without myasthenia gravis, with only one case published so far.

Syndromes that Link the Endocrine System and Genitourinary Tract.

PubMed

Özlük, Yasemin; Kılıçaslan, Işın

2015-01-01

The endocrine system and genitourinary tract unite in various syndromes. Genitourinary malignancies may cause paraneoplastic endocrine syndromes by secreting hormonal substances. These entities include Cushing`s syndrome, hypercalcemia, hyperglycemia, polycythemia, hypertension, and inappropriate ADH or HCG production. The most important syndromic scenarios that links these two systems are hereditary renal cancer syndromes with specific genotype/phenotype correlation. There are also some very rare entities in which endocrine and genitourinary systems are involved such as Carney complex, congenital adrenal hyperplasia and Beckwith-Wiedemann syndrome. We will review all the syndromes regarding manifestations present in endocrine and genitourinary organs.

Background Paraneoplastic melanocytic proliferation (bilateral diffuse uveal melanocytic proliferation, BDUMP) is a rare but devastating disease that causes progressive visual loss in patients who usually have an occult malignancy. Visual loss occurs as a result of paraneoplastic changes in the uveal tissue. Methods In a masked fashion, the serum of two patients with BDUMP was evaluated for the presence of cultured melanocyte elongation and proliferation (CMEP) factor using cultured human melanocytes. We evaluated the efficacy of plasmapheresis as a treatment modality early in the disease in conjunction with radiation and chemotherapy. Results The serum of the first case patient was investigated after plasmapheresis and did not demonstrate proliferation of cultured human melanocytes. The serum of the second case was evaluated prior to treatment with plasmapheresis and did induce this proliferation. These findings are in accordance with the diminution of CMEP factor after plasmapheresis. Treatment with plasmapheresis managed to stabilise the ocular disease progression in both patients. Conclusions In the past, visual loss due to paraneoplastic melanocytic proliferation was considered progressive and irreversible. We treated two patients successfully with plasmapheresis and demonstrated a relation between CMEP factor in the serum of these patients and proliferation of cultured melanocytes. PMID:25908835

Isolated case reports suggest that breast tumors from patients with paraneoplastic cerebellar degeneration (PCD) and Yo antibodies overexpress human epidermal growth factor receptor 2 (HER2). HER2 overexpression is present in 15%-25% of breast cancers and is associated with poor prognosis. We retrospectively analyzed the status of HER2 in breast tumors of 27 patients with anti-Yo-associated PCD to evaluate whether HER2 overexpression in this group of patients is higher than expected. In addition, we analyzed HER2 status of 19 breast tumors from patients with paraneoplastic neurological syndromes and Ri antibodies to see whether HER2 was specifically related to anti-Yo-associated PCD. We also assessed cdr2 expression (the onconeural antigen recognized by Yo antibodies) in 21 HER2-positive breast tumors from patients without paraneoplastic neurological syndromes. HER2 was overexpressed in 26 patients (96.3%) with anti-Yo-associated PCD but only in 2 patients (10.5%) with paraneoplastic neurological syndromes associated with Ri antibodies (P< .0001). Only 5 (23.8%) of the 21 HER2-positive breast tumors showed cdr2 immunoreactivity. This study shows a very high frequency of HER2 overexpression in breast cancers in patients with anti-Yo-associated PCD but not in those from patients with Ri antibodies. Although the expression of cdr2 onconeural antigen is not high in HER2-positive breast cancers, HER2 overexpression seems to be an important requirement to develop an anti-Yo-associated PCD.

[Anti-VGKC antibody-associated limbic encephalitis/Morvan syndrome].

PubMed

Anti-voltage-gated potassium channel antibodies (anti-VGKC-Ab) cause hyperexcitability of the peripheral nerve and central nervous system. Peripheral nerve hyperexcitability is the chief manifestation of Issacs syndrome and cramp-fasciculation syndrome. Morvan syndrome is characterized by neuromyotonia with autonomic and CNS involvement. Manifestations involving the CNS without peripheral involvement are characteristic of limbic encephalitis and epilepsy. The clinical features of anti-VGKC-Ab-associated limbic encephalitis are subacute onset of episodic memory impairment, disorientation and agitation. Hyponatremia is also noted in most patients. Cortico-steroid therapy, plasma exchange and intravenous immunoglobulin are effective in treating to not only the clinical symptoms but also hyponatremia. Unlike other anti-VGKC-Ab-associated neurological disorders, paraneoplastic cases are rare. Thus, anti-VGKC-Ab-associated limbic encephalopathy is considered to be an autoimmune, non-paraneoplastic, potentially treatable encephalitis. Morvan syndrome is characterized by widespread neurological symptoms involving the peripheral nervous system (neuromyotonia), autonomic system (hyperhidrosis, severe constipation, urinary incontinence, and cardiac arrhythmia) and the CNS (severe insomnia, hallucinations, impairment of short-term memory and epilepsy). Many patients have an underlying tumor, for example thymoma, lung cancer, testicular cancer and lymphoma; this indicates the paraneoplastic nature of the disease. Needle electro-myography reveals myokimic discharge. In nerve conduction study, stimulus-induced repetitive descharges are frequently demonstrated in involved muscles. Plasma exchange is an effective treatment approach, and tumor resection also improves symptoms. Both VGKC-Ab-associated limbic encephalitis and Morvan syndrome can be successfully treated. Therefore, when these diseases are suspected, it's important to measure the anti-VGKC-Ab level.

Sarcoidosis predominantly affects the lungs, intrathoracic lymph nodes, and eyes; it less frequently affects the musculoskeletal system. We herein report a case of paraneoplastic sarcoidosis in a patient presenting with multiple myeloma. The patient developed ocular sarcoidosis and showed an increased 18 F-fluorodeoxyglucose uptake in the mediastinal lymph nodes and vertebral column. A lymph node specimen showed the histological features of sarcoidosis, while an examination of the vertebral tumor revealed myeloma. Although the simultaneous occurrence of sarcoidosis and myeloma is extremely rare, our case indicates the importance of exculing any underlying malignancies before establishing a diagnosis of skeletal sarcoidosis when bone lesions are observed at unusual sites.

We present a 27-yr-old female with gonadal dysgenesis (46, XY), who presented to our hospital with poor consciousness, aphasia, restlessness, and visual hallucination. Physical examination revealed normal breast development and normal external female genetalia. Computed tomography scan of the head and neck revealed the presence of brain edema, hydrocephalous, and a localized hypodense lesion in the hypothalamus. Her serum was positive for the anti-Ma2, which is associated with paraneoplastic encephalitis syndrome. Computed tomography of the abdomen revealed the presence of a 7.5×5.3×3.0 cm solid pelvic mass. Interestingly, a single microscopic focus of dysgerminoma was identified in a background of stromal fibrosis and focal dystrophic calcifications. No ovarian stroma or testicular tissue was identified. To our knowledge, this is the first case of gonadal dysgenesis presenting with anti-Ma2 paraneoplastic encephalitis with dysgerminoma. A discussion about paraneoplastic encephalitis with a microscopic dysgerminoma associated with anti-Ma2 antibody is presented.

Paraneoplastic neurological syndromes (PNS) are devastating neurological disorders secondary to cancer, associated with onconeural autoantibodies. Such antibodies are directed against neuronal antigens aberrantly expressed by the tumor. The detection of onconeural antibodies in a patient is extremely important in diagnosing a neurological syndrome as paraneoplastic (70% is not yet known to have cancer) and in directing the search for the underlying neoplasm. At present six onconeural antibodies are considered 'well characterized' and recognize the antigens HuD, CDR62 (Yo), amphiphysin, CRMP-5 (CV2), NOVA-1 (Ri), and Ma2. The gold standard of detection is the characteristic immunohistochemical staining pattern on brain tissue sections combined with confirmation by immunoblotting using recombinant purified proteins. Since all six onconeural antibodies are usually analyzed simultaneously and objective cut-off values for these analyses are warranted, we developed a multiplex assay based on Luminex technology. Reaction of serial dilutions of six onconeural standard sera with microsphere-bound antigens showed lower limits of detection than with Western blotting. Using the six standard sera at a dilution of 1:200, the average within-run coefficient of variation (CV) was 4% (range 1.9-7.3%). The average between-run within-day CV was 5.1% (range 2.9-6.7%) while the average between-day CV was 8.1% (range 2.8-11.6%). The shelf-life of the antigen coupled microspheres was at least two months. The sensitivity of the multiplex assay ranged from 83% (Ri) to 100% (Yo, amphiphysin, CV2) and the specificity from 96% (CV2) to 100% (Ri). In conclusion, Luminex-based multiplex serology is highly reproducible with high sensitivity and specificity for the detection of onconeural antibodies. Conventional immunoblotting for diagnosis of onconeural antibodies in the setting of a routine laboratory may be replaced by this novel, robust technology. Copyright © 2013 Elsevier B.V. All rights

Hepatocelluar carcinoma is one of the commonest cancers in Nigeria. Some patients may manifest a variety of paraneoplastic syndromes. Carcinoid syndrome is an extremely rare presentation of hepatocellular carcinoma. A 57-year old man presented with recurrent facial flushing and diarrhea, tricuspid regurgitation, and very high level of urinary hydroxyindoleacetic acid (HIAA) as the first manifestation of a multicentric hepatic lesion which proved histologically to be hepatocellular carcinoma. The lesions also exhibited arterial hypervascularization on contrast enhanced computerized tomography. The patient is still alive after 6 years of symptoms. PMID:27956985

Paraneoplastic limbic or brainstem encephalitis is considered to be an autoimmune-mediated disorder of the nervous system associated with different types of cancer including germ cell tumors. We report on a 31-year-old patient presenting with eye motility dysfunction, dysarthrophonia, lethargy, depression, slow mentation, disorientation, dysgraphia, and retarded motion sequence. Neurologic tests, brain imaging, and blood chemistry tests failed to determine the cause of the symptoms. Further examinations including ultrasound of the abdomen led to the detection of a retroperitoneal mass. The biopsy of this mass showed fractions of a choriocarcinoma. The patient underwent curative chemotherapy, but although the cancer therapy was successful, the neurologic disorders did not improve. Concurrent examination for anti-Ma2 antibodies in the serum was positive and confirmed the paraneoplastic origin of these symptoms. Patients with symptoms of limbic or brainstem encephalitis, especially young men, should be tested for anti-Ma2 antibodies in the serum to elucidate their origin. The detection of these antibodies supports the diagnosis of a paraneoplastic syndrome, and may lead to the earlier identification of an otherwise hidden extragonadal germ cell tumor.

To analyze the clinical characteristics of paraneoplastic retinopathy and optic neuropathy(PRON). Case series study. Eight patients were enrolled from October 2006 to March 2012 visited in ophthalmology department, the People Liberation Army General Hospital. The patients were underwent a series of examinations, including fundus photography, visual electrophysiology, fundus fluorescein angiography, optic coherent tomography,fundus autofluorescent imaging, perimetry, ultrasonography, magnetic resonance imaging, spinal tap and cerebrospinal fluid test, paraneoplastic syndrome (PNS) antibody test. The patients were followed up in outpatient department and(or) by phone. The clinical manifestation,entity types, and treatment were analyzed. Of the eight patients, there were cancer associated retinopathy(CAR) 3 cases, bilateral diffuse uveal melanocytic proliferation (BDUMP) 2 cases and paraneoplastic optic neuropathy(PON) 3 cases. Five patients were detected the PNS antibodies and revealed three patients with positive results. As for the primary malignancy,four of the eight patients were lung carcinoma,others included invasive thymoma, kidney cancer, acute lymphocytic leukemia and cervical cancer, each for one case. All the patients complained vision blurring or progressive visual decrease. Other complaints included dark shadow in two patients, shimmering, dazzling, double vision and eye pain, each in one patient. One patient complained progressive decreased vision in both eyes prior to the diagnosis of lung cancer. Of the 16 eyes of the eight patients, there were six patients with no light perception vision, five from light perception to 0.05, and other five with no less than 0.4 vision, in the end of the follow up. Five patients were treated with steroid with unsatisfactory efficacy. Each entity of PRON has its own clinical characteristics. PRON especially BDUMP may be a pre-metastatic disease.

Acquired lipodystrophy, craniopharyngioma and chronic inflammatory demyelinating polyneuropathy (CIDP) are individually rare disorders, and have never before been reported in a single patient. A 15-year-7 month old Caucasian male presented with lower extremity weakness, frequent falls and abnormal fat distribution occurring over the previous 1 year. He was diagnosed with CIDP, craniopharyngioma and acquired lipodystrophy. The patient underwent tumor debulking and cranial irradiation for the craniopharyngioma, and received monthly intravenous immunoglobulin for the CIDP. The patient initially had some resolution of the lipodystrophy phenotype, but subsequently the abnormal fat distribution recurred and the patient developed additional systemic abnormalities, including mild pancytopenia and hepatic fibrosis. Our patient represents a novel association of acquired lipodystrophy, craniopharyngioma, and CIDP, possibly due to an as yet unidentified paraneoplastic autoantibody.

2017-01-01

Patient: Female, 48 Final Diagnosis: Inclusion body myositis Symptoms: Shortness of breath • weakness Medication: — Clinical Procedure: Biopsy Specialty: Neurology Objective: Rare disease Background: Sporadic inclusion body myositis (IBM) is the most common acquired myopathy seen in adults aged over 50 years, with a prevalence estimated at between 1 and 70 per million. Weakness of the diaphragm with loss of vital capacity is almost universal in IBM. This is almost always asymptomatic. When respiratory complications occur, they are most often due to aspiration. Respiratory failure due to diaphragmatic weakness is exceptionally rare, particularly as the presenting symptom of the disease. It is not currently considered to be a paraneoplastic syndrome. Case Report: Our patient presented with hypercarbic respiratory failure. This is the first such reported case without signs of weakness elsewhere of which we are aware. We suspected IBM based on her history of progressive weakness and findings on electromyography. There was a delay of 5 years in obtaining biopsy for confirmation, during which she presented with recurrent episodes of respiratory failure despite using non-invasive ventilation. An autopsy revealed the presence of papillary thyroid carcinoma with spread to local lymph nodes. On the basis that these co-morbidities are unlikely to have occurred by chance (we estimate 1×10−17), we hypothesize that IBM may be a paraneoplastic condition. We acknowledge that proof would require demonstrating a pathogenic antibody. Conclusions: IBM should be considered in older patients (age >45) presenting with otherwise unexplained respiratory failure. A workup for possible malignancy in this setting appears reasonable.

Onconeural antibodies are associated with cancer and paraneoplastic encephalitis. While their pathogenic role is still largely unknown, their high diagnostic value is undisputed. In this study we describe the discovery of a novel target of autoimmunity in an index case of paraneoplastic encephalitis associated with urogenital cancer.A 75-year-old man with a history of invasive bladder carcinoma 6 years ago with multiple recurrences and a newly discovered renal cell carcinoma presented with seizures and progressive cognitive decline followed by super-refractory status epilepticus. Clinical and ancillary findings including brain biopsy suggested paraneoplastic encephalitis. Immunohistochemistry of the brain biopsy was used to characterize the inflammatory response. Indirect immunofluorescence assay (IFA) was used for autoantibody screening. The autoantigen was identified by histo-immunoprecipitation and mass spectrometry and was validated by expressing the recombinant antigen in HEK293 cells and neutralization tests. Sera from 125 control patients were screened using IFA to test for the novel autoantibodies.IFA analysis of serum revealed a novel autoantibody against brain tissue. An intracellular enzyme, Rho-associated protein kinase 2 (ROCK2), was identified as target-antigen. ROCK2 was expressed in affected brain tissue and archival bladder tumor samples of this patient. Brain histopathology revealed appositions of cytotoxic CD8 + T cells on ROCK2-positive neurons. ROCK2 antibodies were not found in the sera of 20 patients with bladder cancer and 17 with renal cancer, both without neurological symptoms, 49 healthy controls, and 39 patients with other antineuronal autoantibodies. In conclusion, novel onconeural antibodies targeting ROCK2 are associated with paraneoplastic encephalitis and should be screened for when paraneoplastic neurological syndromes, especially in patients with urogenital cancers, occur.

Lateral Medullary Syndrome (LMS) is a well-documented vascular syndrome of the posterior circulation territory. This syndrome is easily localised because of characteristic presentation, unique territory of blood supply and very small area of involvement. We present a case of Wallenberg’s syndrome which did not have all the classical components of the syndrome, like Horner’s syndrome. Opalski syndrome is a rare variant of Wallenberg syndrome, where lateral medullary syndrome is associated with ipsilateral hemiparesis. This case report highlights how differential involvement of the lateral part of medulla can result in varied presentation. PMID:25177595

Paraneoplastic limbic encephalitis and possible narcolepsy in a patient with testicular cancer: case study.

PubMed Central

We describe a patient who presented with a clinical syndrome of limbic encephalitis, narcolepsy, and cataplexy. The anti-Ma2 antibody was positive. Although there was no mass on imaging, orchiectomy was performed in this patient, and testicular carcinoma was found. This is the first known case of limbic encephalitis and anti-Ma2 antibody to be associated with cataplexy and possible narcolepsy. Neurological symptoms precede the diagnosis of cancer in 50% of patients with paraneoplastic syndromes, and clinicians are therefore strongly advised to evaluate patients with neurological symptoms for this condition.

Normalization of cortisol concentration by multikinase inhibitors have been reported in three patients with medullary thyroid cancer-related Cushing's syndrome. Aortic dissection has been reported in three patients with Cushing's syndrome. Diabetes insipidus without intrasellar metastasis, intestinal intussusception, and paraneoplastic dysautonomia have not been reported in medullary thyroid cancer. An adult male with metastatic medullary thyroid cancer presented with hyperglycemia, hypernatremia, hypokalemia, hypertension, acne-like rash, and diabetes insipidus (urine volume >8 L/d, osmolality 190 mOsm/kg). Serum cortisol, adrenocorticoitropic hormone, dehydroepiandrostenedione sulfate, and urinary free cortisol were elevated 8, 20, 4.4, and 340 folds, respectively. Pituitary imaging was normal. Computed tomography scan revealed jejunal intussusception and incidental abdominal aortic dissection. Sorafenib treatment was associated with Cushing's syndrome remission, elevated progesterone (>10 fold), normalization of dehydroepiandrostenedione sulfate, but persistently elevated cortisol concentration. Newly-developed proximal lower limb weakness and decreased salivation were associated with elevated ganglionic neuronal acetylcholine receptor (alpha-3) and borderline P/Q type calcium channel antibodies. Extreme cortisol concentration may have contributed to aortic dissection and suppressed antidiuretic hormone secretion; which combined with hypokalemia due cortisol activation of mineralocorticoid receptors, manifested as diabetes insipidus. This is the first report of paraneoplastic dysautonomia and jejunal intussusception in medullary thyroid cancer, they may be related to medullary thyroid cancer's neuroendocrine origin and metastasis, respectively. Remission of Cushing's syndrome without measurable reduction in cortisol concentration suggests a novel cortisol-independent mechanism of action or assay cross-reactivity.

The Utility of FDG-PET/CT in Clinically Suspected Paraneoplastic Neurological Syndrome: A Literature Review and Retrospective Case Series.

2017-01-01

Paraneoplastic neurological syndrome (PNS) describes a spectrum of rare, heterogeneous neurological conditions associated with an underlying malignancy. Diagnosis of PNS is inherently difficult, with frequent misdiagnosis and delay. The literature suggests an underlying immune-mediated pathophysiology, and patients are usually tested for the presence of onconeural antibodies. With direct tumor therapy being the most effective method of stabilizing patients, there is a strong emphasis on detecting underlying tumors. The sensitivity of conventional CT imaging is often inadequate in such patients. While FDG-PET imaging has already been shown to be effective at detecting these tumors, FDG-PET/CT, combining both structural and functional imaging in a single study, is a more recent technique. To study the utility of FDG-PET/CT, we conducted a systematic literature review and a retrospective study. We identified 41 patients who underwent imaging for clinically suspected PNS at the regional PET-CT and neurosciences center based at the Royal Preston Hospital between 2007 and 2014 and compared the results to conventional investigations. Five patients had FDG-PET/CT tracer avidity suspicious of malignant disease, and four of these were subsequently diagnosed with cancer. Sensitivity and specificity were calculated to be 100 and 97.3%, respectively, with positive predictive value 80% and negative predictive value 100%. This compares to a sensitivity and specificity of 50 and 100%, respectively, for CT and 50 and 89%, respectively, for onconeural antibodies. These findings are in line with previous studies and support the diagnostic accuracy of FDG-PET/CT for the detection of underlying malignancy.

Dentofacial anomalies may guide us to the diagnosis of many congenital and hereditary syndromes. A 9-year-old boy was diagnosed with Nance–Horan syndrome. This syndrome is an extremely rare X-linked genetic disorder which is entirely expressed in males with semi-dominant transmission which results from mutations occurring in male gametes. It is characterized by facial dysmorphism such as long face, prominent nose and mandibular prognathism, ocular abnormalities such as congenital cataract, microcornea, microphthalmia and strabismus, and dental anomalies including mulberry molars and screwdriver-shaped incisors. Heterozygous females inherit this disease and also suffer from this syndrome but in a milder form. Approximately one-third of the affected males show signs of developmental delay and intellectual abnormalities. This syndrome is very rare and the incidence of the disease has not been established so far. The present article describes the clinical and radiological features and the genetic implications of this syndrome. PMID:29042737

Memory loss can be a symptom of paraneoplastic limbic encephalitis (PLE) a neuropsychiatric disorder associated mostly with small-cell lung cancer and anti-Hu antibodies or with testicular tumors and anti-Ma2 antibodies. We present the case of a patient with temporal coincidence of beginning cognitive decline and diagnosis of a carcinoma of the prostate in whom we diagnosed anti-Ma1/Ma2-positive PLE. The tumor had been completely resected but memory impairment further deteriorated. As the effective treatment of the cancer is considered as the most efficient treatment of a paraneoplastic neurological syndrome (PNS) a second neoplasia was suspected in the patient. By the aid of whole body positron emission tomography with 18-fluorine fluoro-2-deoxy-glucose (FDG-PET) an adenocarcinoma of the cecum could be detected. Two months after surgery anti-Ma antibodies were negative. We conclude that a second neoplasia should be considered, if effective cancer treatment does not lead to improvement or stabilisation of a PNS. Tumor search should be exhaustive and include PET when conventional imaging fails to show a malignancy.

Sarcoidosis is a well-described disease that can be associated with various malignancies; however, this correlation is still not fully clarified. To determine the clinical and histological features, demographic characteristics, and prognosis of patients diagnosed with paraneoplastic sarcoidosis (PS). This observational cohort prospective study included all patients diagnosed as cutaneous sarcoidosis. All patients were monitored for therapeutic response, prognosis, and any associated diseases or malignancies. Out of 94 patients with cutaneous sarcoidosis, we identified 12 patients (12.8%) with PS. There was a male (n = 8) preponderance (ratio 2 : 1),and the mean ± SD age of patients was 64.6 ± 13.21 years. The spectrum of paraneoplastic malignancies included six cases of Hodgkin lymphoma, five of multiple myeloma and one of non-Hodgkin lymphoma (NHL; diffuse large B-cell lymphoma). The underlying malignancy was usually diagnosed within 4-25 months (mean ± SD 12.7 ± 6.85) from diagnosis of cutaneous sarcoidosis. The response to systemic steroid was relatively poor and patients on combination therapy showed frequent relapses. However, after treatment of the associated malignancy, seven patients (58.3%) showed complete resolution of the lesions and five (41.7%) showed moderate improvement. During follow-up, there was no relapse reported for either PS or malignancy. Our results suggest that sarcoidosis is a new subset in the spectrum of paraneoplastic syndrome. We propose that lymphoproliferative disorders should be considered in patients with cutaneous sarcoidosis who have a poor response to conventional therapy or whose skin biopsy shows a significant number of mitoses. © 2018 British Association of Dermatologists.

Inclusion Body Myositis: A Case Presenting with Respiratory Failure and Autopsy Findings Leading to the Hypothesis of a Paraneoplastic Cause.

Dardis, Christopher; Antezana, Ariel; Tanji, Kurenai; Maccabee, Paul J

2017-06-23

BACKGROUND Sporadic inclusion body myositis (IBM) is the most common acquired myopathy seen in adults aged over 50 years, with a prevalence estimated at between 1 and 70 per million. Weakness of the diaphragm with loss of vital capacity is almost universal in IBM. This is almost always asymptomatic. When respiratory complications occur, they are most often due to aspiration. Respiratory failure due to diaphragmatic weakness is exceptionally rare, particularly as the presenting symptom of the disease. It is not currently considered to be a paraneoplastic syndrome. CASE REPORT Our patient presented with hypercarbic respiratory failure. This is the first such reported case without signs of weakness elsewhere of which we are aware. We suspected IBM based on her history of progressive weakness and findings on electromyography. There was a delay of 5 years in obtaining biopsy for confirmation, during which she presented with recurrent episodes of respiratory failure despite using non-invasive ventilation. An autopsy revealed the presence of papillary thyroid carcinoma with spread to local lymph nodes. On the basis that these co-morbidities are unlikely to have occurred by chance (we estimate 1×10-17), we hypothesize that IBM may be a paraneoplastic condition. We acknowledge that proof would require demonstrating a pathogenic antibody. CONCLUSIONS IBM should be considered in older patients (age >45) presenting with otherwise unexplained respiratory failure. A workup for possible malignancy in this setting appears reasonable.

Neonatal Cushing Syndrome: A Rare but Potentially Devastating Disease.

PubMed

Tatsi, Christina; Stratakis, Constantine A

2018-03-01

Neonatal Cushing syndrome (CS) is most commonly caused by exogenous administration of glucocorticoids and rarely by endogenous hypercortisolemia. CS owing to adrenal lesions is the most common cause of endogenous CS in neonates and infants, and adrenocortical tumors (ACTs) represent most cases. Many ACTs develop in the context of a TP53 gene mutation, which causes Li-Fraumeni syndrome. More rarely, neonatal CS presents as part of other syndromes such as McCune-Albright syndrome or Beckwith-Wiedemann syndrome. Management usually includes resection of the primary tumor with or without additional medical treatment, but manifestations may persist after resolution of hypercortisolemia.

Signs and genetics of rare cancer syndromes with gastroenterological features

Bruno, William; Fornarini, Giuseppe; Ghiorzo, Paola

2015-01-01

Although the genetic bases of most hereditary cancer syndromes are known, and genetic tests are available for them, the incidence of the most rare of these syndromes is likely underestimated, partially because the clinical expression is neither fully understood nor easily diagnosed due to the variable and complex expressivity. The clinical features of a small pool of rare cancer syndromes include gastroenterological signs, though not necessarily tumors, that could require the intervention of a gastroenterologist during any of the phases of the clinical management. Herein we will attempt to spread the knowledge on these rare syndromes by summarizing the phenotype and genetic basis, and revising the peculiar gastroenterological signs whose underlying role in these rare hereditary cancer syndromes is often neglected. Close collaboration between geneticists and gastroenterologists could facilitate both the early identification of patients or relatives at-risk and the planning of multidisciplinary and tailored management of these subjects.

Male, 67 FINAL DIAGNOSIS: Remitting seronegative symmetrical synovitis with pitting edema (RS3PE) syndrome Symptoms: Bilateral wrist swelling Medication: - Clinical Procedure: - Specialty: Rheumatology. Unusual or unexpected effect of treatment. Remitting seronegative symmetrical synovitis with pitting edema (RS3PE) syndrome is a rare clinical entity characterized by the sudden onset of inflammatory arthritis and marked pitting edema on upper and lower extremities. RS3PE is considered a rheumatic process distinct from rheumatoid arthritis, which may occasionally represent a paraneoplastic syndrome. Herein, we describe a rare case of RS3PE associated with insulin therapy in a patient with no evidence of underlying malignancy. To the best of our knowledge, this is the first case report of RS3PE associated with insulin therapy. Physicians should look at the introduction of drugs as possible triggers for the development of RS3PE.

This study aimed to determine the diagnostic impact of (18)F-FDG PET/CT based on the clinical features of paraneoplastic neurological syndrome (PNS). Multicenter retrospective and longitudinal study of patients with suspicion of PNS. The clinical picture was classified into classic (CS) and non-classic syndrome (NCS). After the follow-up, the definitive or possible diagnosis of PNS was established. The pictures that did not match any of the previous criteria were categorized as non-classifiable. The state of the onco-neural antibodies was studied. The PET/CT was classified as positive or negative for the detection of malignancy. The relationship between PET/CT findings and the final diagnosis was determined. The differences between variables (Pearson test X(2)) and the relationship between the results of the PET/CT and the final diagnosis were analyzed. A total of 64 patients were analyzed, classifying 30% as CS and 42% as NCS. After the follow-up, 20% and 16% of subjects were diagnosed as possible and definitive PNS, respectively. Positive onco-neural antibodies were found in 13% of the patients. A definitive diagnosis of PNS was associated with a positive PET/CT (P=.08). A significant relation between antibodies expression and final diagnosis of neoplasia (P=.04) was demonstrated. The PET/CT correctly localized malignancy in 5/7 cases of invasive cancer. The PET/CT showed a higher percentage of positive results in patients with definitive diagnosis of PNS. Despite the low prevalence of malignancy in our series, the PET/CT detected malignancy in a significant proportion of patients with invasive cancer.

Pulmonary neuroendocrine tumors (NET) form a heterogeneous group of rare diseases. In these tumors, paraneoplastic syndromes have been described to drive the course of the disease, among them acromegaly induced by paraneoplastic secretion of growth hormone-releasing hormone (GHRH). We report the case of a 43 years old patient initially diagnosed with acromegaly accompanied by weight gain and acral enlargement. Subsequently, further diagnostic work-up identified a solitary pulmonary neuroendocrine tumor (NET). Laboratory tests revealed markedly increased growth hormone (GH) and insulin-like growth factor 1 (IGF-1) without GHRH elevation in the absence of pituitary pathologies confirming the paraneoplastic origin of clinical presentation with acromegaly. Curative surgery was performed leading to normalization of the elevated hormone levels and improvement of the clinical symptoms. Immunohistochemically, a typical carcinoid (TC) was seen with low proliferation index and abundant IGF-1 expression. The association of acromegaly and pulmonary NET has only rarely been reported. We present an individual case of paraneoplastic GH- and IGF-1 secretion in a patient with pulmonary NET. Based on their rarity, the knowledge of paraneoplastic syndromes occurring in patients with pulmonary NET such as acromegaly due to paraneoplastic GH- and IGF-1 secretion is mandatory to adequately diagnose and treat these patients.

In this paper a review is presented of the rare combination of Klinefelter's syndrome and Prader-Willi syndrome (PWS) and a second case of this combination with a uniparental disomy (UPD) etiology of PWS is described. Patients outlined in all other 8 reports and the present case have a PWS phenotype. Virtually no information is available on the behavioral and psychopathological phenotype in this combination. The latter may be explained by the observation that psychiatric syndromes are especially prevalent in PWS patients with a UPD. It is concluded that instability in mood and behavior in this and other syndromes should be preferentially treated with mood stabilizing agents. Copyright (c) 2007 S. Karger AG, Basel.

Paraneoplastic cerebellar degenerations with anti-Yo antibodies (Yo-PCD) are rare syndromes caused by an auto-immune response against neuronal antigens (Ags) expressed by tumor cells. However, the mechanisms responsible for such immune tolerance breakdown are unknown. We characterized 26 ovarian carcinomas associated with Yo-PCD for their tumor immune contexture and genetic status of the 2 onconeural Yo-Ags, CDR2 and CDR2L. Yo-PCD tumors differed from the 116 control tumors by more abundant T and B cells infiltration occasionally organized in tertiary lymphoid structures harboring CDR2L protein deposits. Immune cells are mainly in the vicinity of apoptotic tumor cells, revealing tumor immune attack. Moreover, contrary to un-selected ovarian carcinomas, 65% of our Yo-PCD tumors presented at least one somatic mutation in Yo-Ags, with a predominance of missense mutations. Recurrent gains of the CDR2L gene with tumor protein overexpression were also present in 59% of Yo-PCD patients. Overall, each Yo-PCD ovarian carcinomas carried at least one genetic alteration of Yo-Ags. These data demonstrate an association between massive infiltration of Yo-PCD tumors by activated immune effector cells and recurrent gains and/or mutations in autoantigen-encoding genes, suggesting that genetic alterations in tumor cells trigger immune tolerance breakdown and initiation of the auto-immune disease.

A rare case of this syndrome observed in a 13-year-old male patient is presented in which multiple OKCs were causing disfigurement of the lower jaw as well as displacement and malocclusion of the teeth. Early diagnosis and treatment of this syndrome is important to reduce the severity of complications including cutaneous and cerebral malignancy and oromaxillofacial deformation and destruction due to jaw cysts.

Patient: Male, 67 Final Diagnosis: Remitting seronegative symmetrical synovitis with pitting edema (RS3PE) syndrome Symptoms: Bilateral wrist swelling Medication: — Clinical Procedure: — Specialty: Rheumatology Objective: Unusual or unexpected effect of treatment Background: Remitting seronegative symmetrical synovitis with pitting edema (RS3PE) syndrome is a rare clinical entity characterized by the sudden onset of inflammatory arthritis and marked pitting edema on upper and lower extremities. RS3PE is considered a rheumatic process distinct from rheumatoid arthritis, which may occasionally represent a paraneoplastic syndrome. Case Report: Herein, we describe a rare case of RS3PE associated with insulin therapy in a patient with no evidence of underlying malignancy. Conclusions: To the best of our knowledge, this is the first case report of RS3PE associated with insulin therapy. Physicians should look at the introduction of drugs as possible triggers for the development of RS3PE. PMID:24696753

Raimundo, Miguel; Fonseca, Cristina; Silva, Rufino; Figueira, João

2018-05-01

Alport syndrome is a rare condition characterized by the clinical triad of nephritic syndrome, sensorineural deafness, and ophthalmological alterations. Herein, we present a rare case of a patient diagnosed with Alport syndrome and bilateral giant macular holes. A 40-year-old woman with a previously unreported mutation in the COL4A4 gene suggestive of autosomal-recessive Alport syndrome presented at our department. The patient exhibited bilateral full-thickness macular holes measuring >1500 µm at their smallest diameters. The very large dimensions of both macular holes were indicative of a bad prognosis regarding hole closure, and a conservative approach was adopted. The patient was maintained on renal substitution therapy, and genetic counseling was offered to other family members. Ophthalmological findings associated to Alport syndrome commonly include anterior lenticonus and dot-and-fleck retinopathy, although giant macular holes can also be associated with this condition. A multidisciplinary approach is crucial in the management of these patients, as Alport syndrome is an inherited systemic basement membrane disease.

2014-01-01

Herlyn-Werner-Wunderlich (HWW) syndrome is a rare müllerian duct anomaly with uterus didelphys, unilateral obstructed hemivagina, and ipsilateral renal agenesis. Patients with this syndrome generally present after menarche with pelvic pain and mass and, rarely, primary infertility in later years. Strong suspicion and knowledge of this syndrome are mandatory for an accurate diagnosis. A 14-year-old female patient presented with acute retention of urine and abdominopelvic pain. Her condition was diagnosed with the use ultrasonography and magnetic resonance imaging as a case of HWW syndrome. She was treated with vaginal hemiseptal resection. The HWW syndrome should be considered among the differential diagnoses in girls with renal anomalies presenting with pelvic mass, symptoms of acute abdominal pain, and acute urinary retention.

Paraneoplastic neurological diseases (PND) are rare, but potentially treatable disorders. Paraneoplastic encephalitis is rapidly emerging as an important but likely under-recognized condition in children. The aim of this study was to assess the prevalence and spectrum of PND in children with benign ovary tumor and the long-term outcome. We retrospectively reviewed the charts of all female patients below 18years of age diagnosed with a benign ovarian tumor proven by pathology between January 1993 and December 2010. All the clinical symptoms developed within 5years of tumor diagnosis and the related investigations were recorded. There were total 133 children and adolescents with benign ovarian tumors, mostly mature teratoma. Six patients (4.5%) had neuropsychiatric manifestations and all but one were beyond age 10years. The most common neuropsychiatric presentations were depression or low mood (84%), headache (50%), mutism (50%), hypoventilation (50%), seizures (30%), hallucination (30%), vomiting and hypersalivation (30%). Three patients (2.2%) had serious PND including acute disseminated encephalomyelitis in 1 and anti-N-methyl-d-aspartate receptor (NMDAR) encephalitis in 2. Although all of three improved after tumor removal, one without immunotherapy had neurological sequelae and prolonged ICU stay. The prevalence of PND in benign ovary tumor is not so uncommon in children. It is important to survey ovary tumors in female adolescents with subacute presentation of multiple-level involvement of neuraxis where no clear alternate diagnosis is possible. Treatment of serious PND associated with ovary tumors should include immunotherapy in addition to tumor removal. Copyright © 2013 The Japanese Society of Child Neurology. Published by Elsevier B.V.

2011-02-01

Fungal infections of the spine are very rare and usually seen in immunocompromised patients. Acute cauda equina syndrome presenting in an immunocompetent patient is usually due to a prolapse of the intervertebral disc. Infective pathology caused by Mycobacterium tuberculosis with epidural collection can also have a similar presentation. We present a case of spinal epidural abscess caused by Aspergillus fumigatus, presenting as acute cauda equina syndrome. To the best of our knowledge, spinal aspergillosis presenting as cauda equina syndrome in an immunocompetent patient has not been reported before in the English-language based medical literature. Surgical decompression with antifungal treatment with oral itraconazole yielded a good recovery.

A 63-year-old female with no significant past medical history was presented with a 5-day history of progressive opsoclonus-myoclonus, headaches, and fevers. Her workup was significant only for positive West-Nile Virus serum serologies. She received a 2-day course of intravenous immunoglobulin (IvIG). At an 8-week follow up, she had a complete neurological remission. Adult-onset opsoclonus-myoclonus syndrome is a rare condition for which paraneoplastic and infectious causes have been attributed. To our knowledge, this is the first case reported of opsoclonus-myoclonus secondary to West-Nile Virus treated with intravenous immunoglobulin monotherapy.

The syndrome of inappropriate antidiuretic hormone secretion (SIADH) accounts for an important part of hyponatremia cases. The causes of SIADH can be detected almost always. As a rare disorder, Morvan Syndrome can be defined by the sum of peripheral nerve hyperexcitability, autonomic instability and neuropsychiatric features. Antibodies to voltage-gated potassium channels (Anti - VGKC-Ab) including contactin associated protein-like 2 antibodies (CASPR2-Ab) and leucine-rich glioma inactivated protein 1 antibodies (LGI1-Ab) were previously known for the potential association with this condition. We present a Morvan Syndrome in a patient who presented with various neuropsychiatric symptoms and SIADH.

2013-01-01

Odontogenic keratocysts are very well documented in the literature. Multiple odontogenic keratocysts (OKCs) are one of the most frequent features of nevoid basal cell carcinoma syndrome (NBCCS). It is linked with mutation in the PTCH gene (human homolog of the drosophila segment polarity gene, “patched”,). Partial expression of the gene may result in occurrence of only multiple recurring OKC without any associated systemic findings. A rare case of multiple odontogenic keratocysts unassociated with any syndrome is reported, so as to add to the growing number of such cases in the literature. The possibility of this case being a partial expression of the Gorlin-Goltz syndrome is discussed. PMID:24163561

We report a 24-year-old young man who presented with gait disorder preceded by a febrile rash and retroauricular lymph nodes. Three days before admission, he had headache, vertigo, nausea and vomiting followed by gait unsteadiness and movement disorders of limbs and eyes. On examination, he had OMS syndrome. Brain MRI, total body scan, MIBG scintigraphy, tumor markers and onconeural antibodies were normal. Cerebro-spinal fluid (CSF) analysis showed lymphocytic meningitis. Positive serum and CSF immunoglobulin M antibody against rubella virus was demonstrated. He received acyclovir with full recovery within two weeks. We discuss the peculiarities of this association with a literature review. This observation enlarges the spectrum of neurological manifestations of rubella as well as that of OMS etiologies.

Opsoclonus-myoclonus syndrome, also named Myoclonic Encephalopathy of Infants, Opsoclonus- Myoclonus Ataxia, Dancing Eyes - Dancing Feet Syndrome, Dancing Eyes Syndrome, Kinsbourne syndrome, is a rare, paraneoplastic or possibly post-viral chronic neurological disorder. The age of presentation ranges from 6 months to 3 years. In 50% of affected children the syndrome is associated with an underlying occult or clinically apparent neuroblastoma. In most patients the tumour is localized, small and well differentiated, with no NMYC gene copy number amplification. The syndrome may also occur after tumour resection or at relapse. The opsoclonus-myoclonus syndrome can occur in children without neuroblastoma, in such idiopathiccases, the onset of neurological symptoms is related to infection. It is assumed, that in idiopathic cases the syndrome could have developed in the course of neuroblastoma which had undergone a complete spontaneous regression. The most characteristic clinical features of opsoclonus-myoclonus syndrome are: opsoclonus, myoclonus, ataxia, irritability, mutism and sleep disturbances. The disease course is usually long-term with episodes of remission and relapses. Approximately 80% of children with opsoclonus-myoclonus syndrome suffer from mild to severe neurological handicaps, mainly cognitive impairment. The authors present a 2-year old boy with opsoclonus-myoclonus syndrome preceded by involution of prenatally documented retroperitoneal area tumour.

Currarino syndrome (triad) is an extremely rare condition characterized by presacral mass, anorectal malformation, and sacral bone deformation. The complete form of this syndrome displays all three irregularities. Herein, we report a male case who was admitted to our hospital with symptoms of urinary system infection and persistent constipation 2 years after colostomy operation performed with the indication of rectovestibular fistula and anal atresia, diagnosed as Currarino syndrome based on imaging modalities. In a patient who was admitted because of the presence of anal atresia, in order to preclude potential complications, probable concomitancy of this syndrome should not be forgotten. Early diagnosis is important for the prevention of meningitis, urinary tract infections, and malignant change. PMID:27081429

A typical male looking adolescent with a legal female gender assignment presented with haematuria. Investigations led to the diagnosis of Persistent Mullerian Duct Syndrome. The condition is indeed a rare entity that needs a multidisciplinar team management. Case hypothesis: A case of Persistent Mullerian Duct Syndrome undiagnosed at birth because karyotyping was defaulted, thus resulting in a significant impact on the legal gender assignment and psychosocial aspects. Promising future implications: The reporting of this case is important to create awareness due to its rarity coupled with the rare presentation with hematuria as a possible masquerade to menstruation. There were not only medical implications, but also psychosocial and legal connotations requiring a holistic multidisciplinary management.

Paraneoplastic sensory neuropathy (PSN) usually runs a subacute progressive course, leaving the patient with severe sensory dysfunction in weeks to months. We describe five patients with PSN, high titers of anti-Hu antibodies (type 1 antineuronal nuclear autoantibodies), and an indolent clinical course. The patients had a median age of 55 years (range, 41 to 72). Four had small-cell (3) or undifferentiated large-cell (1) lung cancer. Patients presented with mild, asymmetric sensory symptoms; in two, the neuropathy was predominant in the arms. Two patients also had a visceral neuropathy causing gastrointestinal dysfunction. The PSN was stable or progressed very slowly without treatment for a median of 18 months (range, 5 to 32) and remained so after treatment with immunoglobulins (1 patient), chemotherapy (3), or both therapies (1). All patients were ambulatory, leading an independent life up until the time of the last visit or until death from the tumor (2 patients). The median follow-up was 36 months (range, 22 to 52). A paraneoplastic origin should be considered in patients with mild, very slowly progressive sensory neuropathies.

2013-07-01

Meige's syndrome is a rare neurological syndrome characterized by oromandibular dystonia and blepharospasm. Its pathophysiology is not clearly determined. A 35-year-old female presented to psychiatric department with blepharospasm and oromandibular dystonia with clinical provisional diagnosis of psychiatric disorder (Conversion Disorder). After thorough physical examination including detailed neurological exam and psychiatric evaluation no formal medical or psychiatric diagnosis could be made. The other differential diagnoses of extra pyramidal symptom, tardive dyskinesia, conversion disorder, anxiety disorder were ruled out by formal diagnostic criteria. Consequently with suspicion of Meige's syndrome she was referred to the department of Neurology and the diagnosis was confirmed. Hence, Meige's syndrome could be misdiagnosed as a psychiatric disorder such as conversion disorder or anxiety disorder because clinical features of Meige's syndrome are highly variable and affected by psychological factors and also can be inhibited voluntarily to some extent.

A case is presented of a very rare type of Usher's syndrome detected in a 30-year-old woman in her 28th week of pregnancy. She reported left eye visual impairment with a one-month history. She underwent standard ophthalmologic examination with additional procedures scheduled after childbirth, including fluorescein angiography, visual field (Goldman and Octopus) and electroretinography. Fundus examination revealed pallor of the optic disk, diffuse retinal blood vessel narrowing, no retinal pigmentation, left macular edema, vitreous liquefaction, and posterior vitreous detachment. Goldman perimetry showed narrowing of all isopters to 10 degrees, and Octopus perimetry showed peripheral decrease of retinal sensitivity. Electroretinography confirmed the diagnosis of retinitis pigmentosa sine pigmento. Upon collecting case history records, hearing disorders originating from childhood were discovered. To our knowledge, this type of retinitis in Usher's syndrome has been reported only once in the available literature.

2017-01-01

Gingival fibromatosis with hypertrichosis syndrome is an extremely rare genetic condition characterized by profound overgrowth of hair and gums, as well as other variable features. Gingival fibromatosis is characterized by a large increase in the gingival dimension which extends above the dental crowns, covering them partially or completely. They were found to have a genetic origin, may also occur in isolation or be part of a syndrome, or acquired origin, due to specific drugs administered systemically. Congenital generalized hypertrichosis is a heterogeneous group of diseases with continuing excessive growth of terminal hair without androgenic stimulation. It has informally been called werewolf syndrome because the appearance is similar to that of a werewolf. Various syndromes have been associated with these features such as epilepsy, mental retardation, cardiomegaly, or osteochondrodysplasia. As so far very few cases have been reported in literature, we are reporting a series of three cases with management of the same. The excess gingival tissues, in these cases, were removed by conventional gingivectomy under general anesthesia. The postoperative result was uneventful and the patient's appearance improved significantly. Good esthetic result was achieved to allow patient to practice oral hygiene measures. Though this is not a serious condition clinically, psychosocial trauma cannot be neglected owing to the cosmetic disfigurement it produces.

2013-10-18

POEMS syndrome (an acronym of polyneuropathy, organomegaly, endocrinopathy, multiple myeloma and skin changes) is a paraneoplastic disorder related to an underlying plasma cell dyscrasia. The development of such a syndrome is rare and its association with calvarial plasmocytoma is even less common, with only two previous reported cases. We describe, in detail, an unusual presentation of cranial plasmocytoma associated with POEMS syndrome and briefly discuss the possible role of surgery in the management of this disease. We present the case of a 45-year-old Caucasian man who was admitted to our department presenting with progressive weakness in his lower limbs, enlarged lymph nodes and a large mass on the scalp with intense bone erosion. POEMS criteria were present and pathological studies confirmed a Castleman's variant plasmocytoma. Clinical status improved noticeably after the excision of the plasmocytoma and the treatment was completed with radiotherapy and steroid pulse therapy. Cranial vault plasmocytoma and its association with POEMS syndrome are rare conditions with few previously reported cases. Although the role of surgery is not clearly defined in POEMS syndrome guidelines, the fact that there seems to be a better prognosis and clinical outcome when surgery is used as a part of the management in POEMS syndrome with cranial vault plasmocytoma is worth discussing.

Cancer and Scleroderma: A Paraneoplastic Disease with Implications for Malignancy Screening

PubMed Central

Shah, Ami A.; Rosen, Livia Casciola

2015-01-01

Purpose of review Recent data suggest a paraneoplastic mechanism of scleroderma pathogenesis in unique subsets of scleroderma patients. In this article, we review these data, explore potential links between cancer and scleroderma, and propose an approach to malignancy screening in scleroderma. Recent findings Emerging data have demonstrated that patients with scleroderma and RNA polymerase III autoantibodies have a significantly increased risk of cancer within a few years of scleroderma onset. Genetic alterations in the gene encoding RNA polymerase III (POLR3A) have been identified, and patients with somatic mutations in POLR3A have evidence of mutation specific T cell immune responses with generation of cross-reactive RNA polymerase III autoantibodies. These data strongly suggest that scleroderma is a by-product of anti-tumor immune responses in some patients. Additional epidemiologic data demonstrate that patients developing scleroderma at older ages may also have a short cancer-scleroderma interval, suggestive of paraneoplastic disease. Summary Scleroderma may be a paraneoplastic disease in unique patient subsets. Aggressive malignancy screening in these patients may aid in early cancer detection. Further study is required to determine whether cancer therapy could improve scleroderma outcomes in this patient population. PMID:26352736

Objective Yo antibodies are associated with paraneoplastic cerebellar degeneration (PCD). We have characterized Yo sera by measuring CDR2 and CDR2L antibodies and the localization of their antigens. Methods Forty-two Yo sera from patients with paraneoplastic neurological syndromes (PNS), 179 sera from ovarian and 114 sera from breast cancer patients without PNS and 100 blood donors were screened for CDR2 and CDR2L antibodies by radioactive immune assay (RIA). Fluorescence microscopy was also used to determine the presence of CDR2 or CDR2L antibodies by staining of HeLa cells transfected with CDR2 or CDR2L fused to green fluorescent protein (GFP). Confocal microscopy was further used to localize the CDR2 and CDR2L proteins. Results RIA showed that 36 of the 42 Yo positive sera contained CDR2 and CDR2L antibodies whereas 6 sera contained only CDR2 antibodies. Five of the ovarian cancer patients had CDR2L antibodies and 4 of the breast cancer patients had either CDR2 or CDR2L antibodies. Only patients with both antibodies had PCD. RIA and staining of transfected cells showed similar results. Yo antibodies were not present in the 100 blood donors. Confocal microscopy showed that CDR2 and CDR2L were localized to the cytoplasm, whereas CDR2L was also present on the cell membrane. Interpretation Yo sera usually contain CDR2 and CDR2L antibodies and both antibodies are associated with PCD. Since only CDR2L is localized to the cell membrane it is likely that CDR2L antibodies may be of primary pathogenic importance for the development of PCD. PMID:23823982

GIANT CELL AORTITIS DIAGNOSED WITH PET/CT - PARANEOPLASTIC SYNDROME?

PubMed

Bakula, Marija; Cerovec, Mislav; Mayer, Miroslav; Huić, Dražen; Anić, Branimir

2016-05-01

Vasculitides are heterogenic group of autoimmune connective tissue diseases which often present difficulties in early diagnosing. Giant cell arteritis is vasculitis of large and medium arteries. It predominantly presents with symptoms of affection of the external carotid artery branches. Furthermore, the only symptoms can be constitutional. In clinical practice, vasculitides are sometimes considered as paraneoplastic, but no definite association with malignancies has been established and the mechanisms are still debated. The gold standard for diagnosing giant cell arteritis is a positive temporal artery biopsy, but the results can often be false negative. Additionally, more than half of the patients have aorta and its main branches affected. Considering aforementioned, imaging studies are essential in confirming large-vessel vasculitis, amongst which is highly sensitive PET/CT. We present the case of a 70-year-old female patient with constitutional symptoms and elevated sedimentation rate. After extensive diagnostic tests, she was admitted to our Rheumatology unit. Aortitis of the abdominal aorta has been confirmed by PET/CT and after the introduction of glucocorticoids the disease soon went into clinical and laboratory remission. Shortly after aortitis has been diagnosed, lung carcinoma was revealed of which the patient died. At the time of the comprehensive diagnostics, there was no reasonable doubt for underlying malignoma. To the best of our knowledge, there are no recent publications concerning giant cell arteritis and neoplastic processes in the context of up-to-date non-invasive diagnostic methods (i.e. PET/CT). In the light of previous research results, we underline that the sensitivity of PET/CT is not satisfactory when estimating cancer dissemination in non-enlarged lymph nodes and that its value can at times be overestimated.

Spine deformities in rare congenital syndromes: clinical issues.

PubMed

Campbell, Robert M

2009-08-01

A focused review of the literature with regard to the important system abnormalities of patients with spinal deformities associated with exotic congenital syndromes with additional data from the author's own experience in assessment of patients with rare syndromes treated for thoracic insufficiency syndrome. The objectives of this study are to emphasize important medical considerations that influence the choice of surgical treatment of spinal deformity in patients with exotic congenital syndromes and point out preoperative strategies that reduce treatment morbidity and mortality of these patients. Individual experience is limited in the treatment of spine abnormality in rare exotic syndromes and the medical aspects of these syndromes that may impact spinal treatment are seldom discussed in detail in the orthopedic literature. For a successful outcome in the treatment of spinal deformity in these unique patients, a working knowledge of the unique pitfalls in their medical care is necessary in order to avoid morbidity and mortality during their treatment. The literature was reviewed for 6 exotic congenital syndromes with known or unreported spinal abnormalities and the author's personal 22-years experience of the treatment of thoracic insufficiency syndrome in the relevant congenital syndromes was summarized. Children with Marfan syndrome and spinal deformity may have serious cardiac abnormalities. Spontaneous dissection of the aortic root is a clear danger and patients should be monitored by serial echocardiograms. Prophylactic cardiac surgery may be necessary before spinal surgery is to be performed. Patients with Jeune syndrome have a high rate of proximal cervical stenosis and should undergo screening with cervical spine films at birth. Significant stenosis or instability may require decompression and cervical-occipital fusion. Arthrogryposis may be associated with a severe scoliosis and jaw contracture may make intubation difficult. Larsen syndrome may have

Poland's syndrome is a rare congenital anomaly consisting of a unilateral absence of the pectoralis major, ipsilateral muscle, hand anomaly and occasionally associated other malformations of the chest wall and breast. Many structural and functional abnormalities have been described in association with this syndrome. We report an incidentally diagnosed case in a 27-year-old male patient who presented to us with symbrachydactyly. In addition to this, anterior depression of 2nd, 3rd and 4th ribs and bifid (forked) 5th rib was present on radiological investigations. The body of sternum was short and deformed on the right side with absence of xiphoid process. All middle phalanges were absent on righthand. It is a rare variant of Poland's syndrome.

IMPORTANCE Reports of neuromyelitis optica spectrum disorder (NMOSD) occurring in the setting of neoplasia suggest that aquaporin-4 autoimmunitymay in some cases have a paraneoplastic basis. OBSERVATIONS In this case report, we describe a patient with NMOSD whose test results were seropositive for aquaporin-4 IgG and who had a hepatic metastasis from a small-bowel neuroendocrine tumor. The tumor cells expressed aquaporin-4 immunoreactivity. She presented to the Neurology Department at Wayne State University with bilateral leg weakness, ascending paresthesias, and decreased sensation. CONCLUSIONS AND RELEVANCE This case extends the context of NMOSD as a paraneoplastic disorder. PMID:24733266

A patient with atypical medullary breast cancer is described who presented with symptoms of limbic encephalitis. The patient's serum and CSF contained antibodies that reacted with the nervous system and the tumour. These antibodies recognised Ma2, a neuronal protein related to paraneoplastic limbic and brainstem encephalitis in men with testicular tumours. This report highlights the importance of testing for paraneoplastic antineuronal antibodies in cases of unexplained limbic encephalitis and suggests screening for breast cancer in women with antibodies predominantly directed to Ma2.

Neonatal Bartter syndrome (NBS) is a rare autosomal recessive renal tubular disorder. This disease is characterized by hypokalemia, hypochloremia, and metabolic alkalosis that is often associated with failure to thrive and recurrent episodes of dehydration. The combination of BS and cholelithiasis in an infant is very rare. Herein, we report a premature male infant with NBS who developed cholelithiasis and hydrocephalus on clinical follow up. We recommend that periodic routine hepatobiliary ultrasonograpic screening for cholelithiasis should be performed in patients with NBS. © 2016 Japan Pediatric Society.

Say Meyer syndrome is rare X linked condition characterized by developmental delay, short stature and metopic suture synostosis. We are reporting a case of Say Meyer syndrome presented to our hospital for short stature and developmental delay at age 3½ years. A 3½-year-old boy presented to our hospital for decreased growth velocity from the age of 1 year. History revealed the boy had a birth weight of 2.3 kg, had an episode of seizures in the neonatal period. He was born to non-consanguineous marriage. He had global developmental delay and there was a lack of bowel and bladder control. History did not reveal any hearing or visual impairment. No history of any chronic systemic illnesses. Magnetic resonance imaging (MRI) brain revealed mild diffuse frontotemporal atrophy with multiple irregular gliotic areas in bilateral frontal lobes. Diffuse white matter volume loss in bilateral cerebral hemispheres. Diffuse thinning of corpus callosum.

Anti-Ma2/Ta antibodies are rare paraneoplastic antibodies, which are mostly associated with limbic encephalitis in male patients with testicular cancer. We report on a 50-year-old woman with a pure progressive spastic paraparesis. Next, she was diagnosed as having a Sjögren syndrome, with serological positivity for anti-SS-Ro antibodies. The patient's serum and cerebrospinal fluid samples were positive for anti-Ma2/Ta antibodies, which were also proved to be intrathecally produced. These findings, and the coexistence of systemic autoimmunity, led us to treat the patient with corticosteroids first, and then with plasma exchange. Neurological symptoms scarcely responded to both the therapies. The search for cancer was negative up to 4 years after the disease onset. Our case expands the spectrum of clinical syndromes associated with anti-Ma2/Ta antibodies.

Prune Belly syndrome: A rare case report

2015-01-01

Prune Belly syndrome (PBS) is a rare congenital anomaly of uncertain etiology almost exclusive to males. We report a case of term male baby born to a 39-year-old grand multipara with previous four normal vaginal births. There was no history of genetic or congenital anomaly in her family. Examination of the baby revealed hypotonia, deficient abdominal muscle, cryptorchidism, palpable kidney, and bladder. Ultrasound examination of the abdomen revealed bilateral gross hydronephrosis and megaureter. Provisional diagnosis of PBS was made and the baby was admitted in neonatal intensive care units for further management. Routine antenatal care with ultrasonography will help in detecting renal anomalies, which can be followed postnatally. Early diagnosis of this syndrome and determining its optimal treatment are very important in helping to avoid its fatal course. PMID:25810678

The utility of diagnostic imaging in paraneoplastic autoimmune multiorgan syndrome (PAMS) is unknown. We examined the role of diagnostic imaging in patients with PAMS evaluated at our tertiary referral center (at Mayo Clinic, Rochester, MN, USA) and in the English literature between January 1, 1996, and August 31, 2012. We included 17 patients from our institution and 208 patients from the literature review. Of these 225 patients, 113 (50.2%) were not known to have a malignancy diagnosis at the time of PAMS diagnosis. Of the 123 patients from our institution and from the literature reported to undergo imaging studies, conventional computed tomography (CT) was the predominant imaging modality (n = 110; 89.4%); 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/CT was also used, albeit infrequently (n = 12; 9.8%). When CT was included in imaging to identify or confirm the presence of a malignancy, imaging was successful in all patients who ultimately were diagnosed with an associated malignancy. At our institution, a relatively high percentage (n = 7; 41%) of patients had 18F-FDG PET/CT, which not only identified all tumors found on CT but also facilitated staging of lymphoma and guided biopsy procedures. Diagnostic imaging is frequently utilized in PAMS with unknown malignancy. Both conventional CT and 18F-FDG PET/CT are likely to detect the typical underlying neoplasms. Relative to conventional CT, 18F-FDG PET/CT may provide additional useful information regarding prognosis for the likely underlying malignancies, although there is a paucity of reports describing the use of this modality for this purpose. © 2014 The International Society of Dermatology.

To determine the efficacy of immunotherapy in limbic encephalitis (LE) associated epilepsies with autoantibodies against intracellular antigens in the forms of paraneoplastic autoantibodies versus glutamic acid decarboxylase 65 (GAD)-autoantibodies. Eleven paraneoplastic-antibodies+ and eleven age- and gender-matched GAD-antibodies+ patients with LE were compared regarding EEG, seizure frequency, MRI volumetry of the brain, and cognition. All patients received immunotherapy with corticosteroids add-on to antiepileptic therapy. A few patients underwent additional interventions like immunoglobulins or immunoadsorption. Immunotherapy led to a significantly greater proportion of seizure-free patients in the paraneoplastic antibodies+(55%) as compared to GAD-antibodies+(18%) patients (p<0.05). Impaired cognition was evident initially (total cognitive performance score based on attentional-executive function, figural/verbal memory and word fluency) in 100% of the paraneoplastic-antibodies+ and 73% of the GAD-antibodies+ group. After therapy, cognition improved significantly in the paraneoplastic-antibodies+, but not in the GAD-antibodies+ patients (p<0.05). Cognitive change did not correlate with the change in the number of antiepileptic drugs over time. MRI showed larger and unchanged volumes of the amygdala, presubiculum and subiculum in GAD-antibodies+as compared to paraneoplastic-antibodies+patients (p<0.05) over time. Our data provide evidence of a beneficial effect of immunotherapy added to antiepileptic drugs on seizure frequency and cognition only in the paraneoplastic-antibodies+ subgroup of LE presenting autoantibodies against intracellular antigens.

Rapid-onset obesity with hypoventilation, hypothalamic dysfunction and autonomic dysregulation (ROHHAD) syndrome is a rare disease that is difficult to diagnosis and distinguish from genetic obesity syndromes. The underlying causes of the disease has not been fully explained. Hypothalamic dysfunction causes endocrine problems, respiratory dysfunction and autonomic alterations. There are around 80 reported patients due to lack of recognition. We present two female patient suspected of ROHHAD due to weight gain since early childhood. The presented symptoms, respiratory and circulatory dysfunction, hypothalamic hypernatremia, hypothalamo-pituitary hormonal disorders such as santral hypothyrodism, hyperprolactinemia and santral early puberty are completely matched the criteria of ROHHAD syndrome. ROHHAD syndrome should be considered in differential diagnosis since it is difficult to distinguish from causes of monogenic obesity. Early identification of the disease reduces morbidity of the syndrome and patients require regular follow-up by a multidisciplinary approach.

Rare neurodevelopmental syndromes often present social cognitive deficits that may underlie difficulties in social interactions and increase the risk of psychosis or autism spectrum disorders. However, little is known regarding the specificities of social cognitive impairment across syndromes while it remains a major challenge for the care. Our review provides an overview of social cognitive dysfunctions in rare diseases associated with psychiatric symptoms (with a prevalence estimated between 1 in 1,200 and 1 in 25,000 live births: 22q11.2 deletion syndrome, Angelman syndrome, Fragile X syndrome, Klinefelter syndrome, Prader–Willi syndrome, Rett syndrome, Smith–Magenis syndrome, Turner syndrome, and Williams syndrome) and shed some light on the specific mechanisms that may underlie these skills in each clinical presentation. We first detail the different processes included in the generic expression “social cognition” before summarizing the genotype, psychiatric phenotype, and non-social cognitive profile in each syndrome. Then, we offer a systematic review of the social cognitive abilities and the disturbed mechanisms they are likely associated with. We followed the PRISMA process, including the definition of the relevant search terms, the selection of studies based on clear inclusion, and exclusion criteria and the quality appraisal of papers. We finally provide insights that may have considerable influence on the development of adapted therapeutic interventions such as social cognitive training (SCT) therapies specifically designed to target the psychiatric phenotype. The results of this review suggest that social cognition impairments share some similarities across syndromes. We propose that social cognitive impairments are strongly involved in behavioral symptoms regardless of the overall cognitive level measured by intelligence quotient. Better understanding the mechanisms underlying impaired social cognition may lead to adapt therapeutic

: Thrombocytopenia, in the setting of microangiopathic hemolytic anemia and thrombotic events, is characteristic of both thrombotic thrombocytopenic purpura and primary antiphospholipid syndrome. Clinically, it is difficult to distinguish between these two syndromes. We present a 41-year-old woman with chronic, relapsing thrombotic thrombocytopenic purpura in the presence of antiphospholipid antibodies. She had clinical manifestations of antiphospholipid syndrome without meeting laboratory criteria of the Sydney classification system. In the literature, there have only been nine cases of thrombotic thrombocytopenic purpura associated with primary antiphospholipid syndrome. Seven of the nine cases suffered from one or multiple strokes, a common feature in antiphospholipid syndrome, but an uncommon finding in thrombotic thrombocytopenic purpura. We introduce the possibility of an association between thrombotic thrombocytopenic purpura and the presence of antiphospholipid antibodies. Systematic testing of ADAMTS13 activity and anti-ADAMTS13 antibodies in patients who present with neurological symptoms and thrombocytopenia, in the presence of antiphospholipid antibodies, may help with the diagnosis of the rare thrombotic thrombocytopenic purpura-antiphospholipid syndrome combination.

Gable, Karissa L; Massey, Janice M

2015-08-01

Lambert-Eaton myasthenic syndrome (LEMS) and botulism are acquired presynaptic nerve terminal disorders of the neuromuscular junction. Lambert-Eaton myasthenic syndrome is an idiopathic or paraneoplastic autoimmune syndrome in which autoantibodies of the P/Q-type voltage-gated calcium channel play a role in decreasing the release of acetylcholine, resulting in clinical symptoms of skeletal muscle weakness, diminished reflexes, and autonomic symptoms. Paraneoplastic LEMS is most often associated with small cell lung cancer. Diagnosis is confirmed by positive serologic testing and electrophysiological studies, which display characteristic features of low compound muscle action potentials, a decrement at 3Hz repetitive nerve stimulation, and facilitation with exercise or high-frequency repetitive stimulation. Treatment involves cancer monitoring and treatment, 3,4-diaminopyridine, immunosuppressive medications, and acetylcholinesterase inhibitors. Botulism is another presynaptic disorder of neuromuscular transmission. Clinical features classically involve cranial and bulbar palsies followed by descending weakness of the limbs, respiratory failure, and autonomic dysfunction. Electrodiagnostic testing is important in the evaluation and diagnosis. Treatment is supportive, and administration of antitoxin is beneficial in selected cases.

Fat embolism syndrome is a clinical diagnosis, and diagnostic procedures are not specific. In every trauma patient, Fat embolism syndrome has to be considered as a possibility and supportive treatment should begin as soon as possible. The authors reported a rare case of Fat embolism syndrome whose only neurological symptom was motor aphasia. A young man sustained comminuted femoral shaft fracture following an accident presented dyspnea, motor aphasia and petechial rash. The Po2 and O2 Saturation were 53 and 91.1%. The body temperature was 38.5 °C. The hemoglobin decreased from 12.9 to 8.7 and platelet from 121000 to 84000 mg/dl. The pulse rate was 120 bpm. The CT scan and MRI were normal. Fat embolism syndrome was diagnosed according to both Gurd and Schonfeld criteria ruling out other possible causes. Patient recovered completely. Although rare, focal neurological symptoms and motor aphasia should be kept in mind as a part of diagnostic criteria.

POEMS syndrome is a paraneoplastic manifestation associated with hematopoietic disorders such as multiple myeloma and Castleman disease. POEMS is an acronym for the main clinical features of the syndrome, namely, Polyneuropathy, Organomegaly, Endocrinopathy, M protein, and Skin abnormalities. Glomeruloid hemangiomas are considered to be a specific clinical marker of POEMS syndrome. However, while they are not pathognomonic, their presence should raise suspicion of this syndrome or alert clinicians to its possible future development, as these lesions can appear years before the onset of the syndrome. We report the cases of 2 women with plasma cell dyscrasias and sudden onset of lesions with a vascular appearance and histologic findings consistent with glomeruloid hemangioma. Recognition of this vascular tumor is important for the early diagnosis of POEMS syndrome. Copyright © 2016 AEDV. Publicado por Elsevier España, S.L.U. All rights reserved.

Hip dislocations are serious injuries as hip joint is an extremely stable joint. It requires a significant amount of force to produce such an injury. Anterior dislocations are uncommon. Potential complications of anterior hip dislocations are a neurovascular injury to femoral vessels or acetabular fractures. We report a rare late complication of Morel-Lavallee syndrome occurring 3 weeks after an anterior dislocation of the hip in a 43-year-old male. The patient presented to us with history. Morel-Lavallee syndrome is a rare complication. However if diagnosed early can be successfully treated with minimal burden to the patient. The authors recommend surgeons to have a high index of suspicion for this syndrome and a stringent follow-up examination of the patient.

This occurrence is rare and, in English literature, three cases defined in children have been observed. In order to draw attention to this rare occurrence, we preferred a 14-year-old male patient with Mirizzi syndrome. In this case, ERCP was performed preoperatively and the diagnosis was carried out with the help of clear visualisation and identification of the tissue structures as well as the stent placed in bile duct; so we protected the patient from the possible iatrogenic injury occurring during surgery.

This study aims to focus on a rare presentation of spinal hydatid cyst as cauda equine syndrome and misdiagnosed as intradural extramedullary (IDEM) benign lesion on magnetic resonance imaging. In this article, we report a case of spinal hydatid cyst masquerading as IDEM tumor, and intraoperatively, we accidently find clumped granuloma with severe arachnoiditis and hydatid cyst in lumber region, which was present as bilateral S1 radiculopathy with cauda equina syndrome. An 11-year-old boy who presented with symptoms and signs of cauda equina syndrome and planned for surgical excision. His radiological impression was IDEM possibly neurofibroma. To our surprise, we found multiple intradural cystic lesions with arachnoiditis. Dissecting in plane cyst was flushed out, and surgical cavity was irrigated with 3% saline. Postoperatively histopathology and serum tests confirmed the diagnosis of hydatid cyst. Hydatid disease is rare cause of cauda equine syndrome which can be miss diagnosed on radiological investigations. A high index of suspicion should be kept especially in a young patient from the Indian subcontinent. PMID:27891041

[Monogenic and syndromic symptoms of morbid obesity. Rare but important].

PubMed

Wiegand, S; Krude, H

2015-02-01

Monogenic and syndromic obesity are rare diseases with variable manifestation. Therefore diagnosis is difficult and often delayed. The purpose of this work was to develop a clinical diagnostic algorithm for earlier diagnosis. Available publications for clinical symptoms and molecular defects of monogenic and syndromic obesity cases were evaluated. Monogenic and syndromic obesity can be expected in cases with early manifestation before the age of 5 years and a BMI above 40 or above the 99th percentile. Syndromic cases are mostly associated with a low IQ and dwarfism. Monogenic cases are associated with additional endocrine defects. Measurement of serum leptin proves the treatable leptin deficiency. Sequencing of the melanocortin-4 receptor gene (MC4R) allows diagnosis of the most frequent monogenic form of obesity. Treatment with a melanocyte-stimulating hormone (MSH) analog can be expected in the future. Early treatment of children with Prader-Willi syndrome can prevent severe obesity. Because in some cases treatment is available, monogenic and syndromic obesity should be diagnosed early. Based on the disease symptoms, serum leptin, and MC4R sequencing, a diagnostic algorithm is proposed, which can be used to diagnose cases of morbid obesity.

Keratitis-ichthyosis-deafness (KID) syndrome is a rare ectodermal dysplasia characterized by generalized erythrokeratotic plaques, sensorineural hearing loss, and vascularizing keratitis. Cutaneous changes and hearing loss typically present in early childhood, whereas ocular symptoms present later. Mutations in the connexin (Cx) 26 gene, GJB2, are now established to underlie many of the affected cases, with the majority of patients harboring the p.D50N mutation. A rare patient demonstrating features of incomplete KID syndrome associated with an uncommon Cx26 gene mutation is described. The patient presented late in adolescence with partial features of KID syndrome. There was limited cutaneous involvement and the rare association of cystic acne. Both hearing impairment and ophthalmic involvement were mild in severity. Genetic mutation analysis revealed a previously described, rare mutation in GJB2, resulting in a glycine to arginine change at codon 12 (p.G12R). This report describes a patient exhibiting characteristics suggestive of a late-onset, incomplete form of KID syndrome with the GJB2 mutation (p.G12R). The p.G12R mutation has only been described in one other patient with KID syndrome, whose clinical presentation was not characterized.

Context: We describe a case of paraneoplastic neurologic syndrome, namely N-Methyl-D-Aspartic acid receptor antibody associated limbic encephalitis, a rare cause of altered mental status in the young. Case Report: A 28 year old Caucasian female nurse presented with acute onset difficulty with word finding and increasing confusion and agitation. She also had visual hallucinations, transient episodes of unresponsiveness, and lingual dyskinesias. Workup including blood, imaging and regular cerebrospinal fluid (CSF) studies was unremarkable. She subsequently developed complex partial seizures. Computerized Tomography scan of chest/abdomen/pelvis revealed a dermoid cyst of the left ovary and CSF N-Methyl-D-Aspartic acid receptor antibody returned positive confirming the diagnosis of paraneoplastic NMDA receptor antibody associated limbic encephalitis. She was treated with methylprednisolone therapy along with plasmapheresis and a left salpingo-opherectomy was performed. The patient showed significant improvement with respect to her cognitive function and had no more seizures. Conclusion: N-Methyl-D-Aspartic acid receptor antibody associated limbic encephalitis is a rare paraneoplastic neurologic syndrome with symptoms including psychiatric manifestations, seizures, language disturbances and autonomic instability. It develops due to antibody induced decrease in N-Methyl-D-Aspartic acid receptors. There is a significant association with ovarian teratoma in >50% female cases. Treatment includes resection of tumor, glucocorticoids, plasmapheresis and Intravenous Immunoglobulin therapy. PMID:22361499

Anti-tumor immune responses are postulated to initiate paraneoplastic neurological disorders when proteins normally restricted to neural cells are expressed as oncoproteins. Mutated oncopeptides could bypass self-tolerant T-cells to activate cytotoxic effector T-lymphocytes and requisite helper T-lymphocytes to stimulate autoantibody production by B-lymphocytes. We investigated muscle-type nicotinic acetylcholine receptor (AChR) antigen expression at transcriptional and protein levels in a small-cell lung cancer line (SCLC) established from a patient with AChR-IgG-positive myasthenia gravis. I We identified mRNA transcripts encoding the two AChR α1-subunit isoforms, and seven alternative-splicing products, three yielding premature stop codons. Despite detecting native muscle-type AChR pentamers in the tumor, we did not identify mutant α1-peptides. However, we found α1-subunit-derived peptides bound to tumor MHC1-protein. In a control SCLC from an ANNA-1(anti-Hu)-IgG-positive patient, we identified MHC1-complexed Hu protein-derived peptides, but not AChR peptides. Our findings support onconeural protein products as pertinent immunogens initiating paraneoplastic neurological autoimmunity. This article is protected by copyright.

Introduction: Iliotibial band (ITB) friction syndrome is a common overuse injury typically seen in active athlete population. A nodular lesion on the inner side of the ITB as an etiology or an accompanying lesion with friction syndrome has rarely been reported. Among such nodular lesions around knee, fibroma of tendon sheath (FTS) is a rare occurrence. All the more intra-articular occurrence is extremely rare. Case Report: A 16-year-old female presented with recurrent pain and movable nodule at the lateral joint area, diagnosed as ITB friction syndrome. The nodule was confirmed as rare intra-articular FTS on the basis of histopathology findings. Conclusion: When nodular lesions around knee are detected on magnetic resonance imaging, a FTS could be included in the differential diagnosis. Etiology and pathogenesis of ITB friction syndrome should be revised in view of such rare presentations. PMID:28630835

Paraneoplastic cerebellar degeneration (PCD) is a rare nonmetastatic neurological complication often associated with ovarian, breast, and other gynecologic cancers. Anti-Yo is one of the antionconeural antibodies found in patients with PCD. It primarily emerges before a malignancy is detected. In this report, we describe an unusual case involving a patient who exhibited anti-Yo-positive PCD 1 year after being diagnosed with ovarian cancer. Histopathology of the resected tissues and Antineuronal antibody testing. The patient was treated with intravenous immunoglobulin (IVIG, 1 g/d) for 1 week and a large-dose of methylprednisolone (0.4 g/kg/d) for 5 days. At the same time, underlying complications were prevented actively, and the peripheral nerves were protected. Although most patients with anti-Yo-positive PCD do not improve after treatment, our patient significantly improved after receiving active and effective treatment.

DiGeorge syndrome is a congenital genetic disorder that affects the endocrine system, mainly the thymus and parathyroid glands. The syndrome produces different symptoms, which vary in severity and character between patients. It manifests with craniofacial dysmorphism and defects in the heart, parathyroid, and thymus. Patients can present with a palatal deformity and nasal speech. This rare entity is caused mainly due to deletion of chromosome 22q11.2. Radiographic evaluation of DiGeorge syndrome is necessary to define aberrant anatomy, evaluate central nervous system, craniofacial abnormalities, musculoskeletal system, and cardiothoracic contents. It also helps in planning surgical procedures and surgical reconstructions. We report a case of DiGeorge syndrome in a 4-month-old neonate and discuss the clinical, imaging, and cytogenetic findings that helped in the diagnosis of this rare entity.

2016-11-01

Urinary tract infection is a common disease in the general population. However, in patients with frequent urinary tract infection, it is important to determine any treatable cause to avoid recurrence. Herlyn-Werner-Wunderlich syndrome or OHVIRA syndrome is a very rare congenital anomaly with uterus didelphys, obstructed hemivagina, and ipsilateral renal agenesis. The earliest presentation of this syndrome is hematocolpos that develops during menstruation and results in dysmenorrhea and a pelvic mass shortly after menarche. Herein, we report a patient with Herlyn-Werner-Wunderlich syndrome manifested with unusual symptoms, delayed onset and without surgery. The unique point of this patient is the partial obstruction of cervico-vaginal junction. Early diagnosis and timely treatment of OHVIRA syndrome can prevent long-term complications, such as recurrent urinary tract infection and infertility. A high index of suspicion is required, even though OHVIRA syndrome is extremely rare and may have an atypical presentation.

Gorlin-Goltz Syndrome, also known as nevoid basal cell carcinoma syndrome (NBCCS), is an autosomal dominant trait caused due to mutations in the patched tumor suppressor gene (PTCH) gene found on the long arm of chromosome 9. The syndrome is characterized by the presence of odontogenic keratocysts (OKCs), basal cell carcinomas, and skeletal malformations. Early diagnosis of the syndrome can be done by pedodontist as OKC is one of the early manifestations of the syndrome. Early diagnosis and treatment is important for long-term prognosis of the syndrome by reducing the severity of cutaneous carcinomas and deformities due to jaw cyst. The present case describes an 11-year-old patient with some typical features of NBCCS, which were diagnosed through its oral and maxillofacial manifestations. This case emphasizes the importance of pedodontist in early recognition of the syndrome. Tandon S, Chauhan Y, Sharma M, Jain M. Gorlin-Goltz Syndrome: A Rare Case Report of a 11-Year-Old Child.

Cushing's syndrome is caused by excessive adrenocorticotropic hormone (ACTH) secretion derived from pituitary corticotroph tumors (Cushing disease) or from non-pituitary tumors (ectopic Cushing's syndrome). Hypercortisolemic features of ectopic Cushing's syndrome are severe, and no definitive treatment for paraneoplastic ACTH excess is available. We aimed to identify subcellular therapeutic targets by elucidating transcriptional regulation of the human ACTH precursor POMC (proopiomelanocortin) and ACTH production in non-pituitary tumor cells and in cell lines derived from patients with ectopic Cushing's syndrome. We show that ectopic hPOMC transcription proceeds independently of pituitary-specific Tpit/Pitx1 and demonstrate a novel E2F1-mediated transcriptional mechanism regulating hPOMC We identify an E2F1 cluster binding to the proximal hPOMC promoter region (-42 to +68), with DNA-binding activity determined by the phosphorylation at Ser-337. hPOMC mRNA expression in cancer cells was upregulated (up to 40-fold) by the co-expression of E2F1 and its heterodimer partner DP1. Direct and indirect inhibitors of E2F1 activity suppressed hPOMC gene expression and ACTH by modifying E2F1 DNA-binding activity in ectopic Cushing's cell lines and primary tumor cells, and also suppressed paraneoplastic ACTH and cortisol levels in xenografted mice. E2F1-mediated hPOMC transcription is a potential target for suppressing ACTH production in ectopic Cushing's syndrome. © 2016 Society for Endocrinology.

2018-03-01

Tumor lysis syndrome is a serious and sometimes lethal complication of cancer treatment that is comprised of a set of metabolic disturbances along with clinical manifestations. Initiating chemotherapy in bulky, rapidly proliferating tumors causes rapid cell turnover that in turn releases metabolites into circulation that give rise to metabolic derangements that can be dangerous. This syndrome is usually seen in high-grade hematological malignancies. Less commonly, tumor lysis syndrome can present in solid tumors and even rarely in genitourinary tumors. In this report, the authors describe a specific case of tumor lysis syndrome in a patient with metastatic prostate cancer following treatment with docetaxel.

The detection of occult cancer in patients suspected of having a paraneoplastic neurological syndrome (PNS) poses a diagnostic challenge. The aim of our study was to perform a systematic review and meta-analysis to assess the diagnostic performance of FDG PET for the detection of occult malignant disease responsible for PNS. A systematic review of the literature (MEDLINE, EMBASE, Cochrane, and DARE) was undertaken to identify studies published in any language. The search strategy was structured after addressing clinical questions regarding the validity or usefulness of the test, following the PICO framework. Inclusion criteria were studies involving patients with PNS in whom FDG PET was performed to detect malignancy, and which reported sufficient primary data to allow calculation of diagnostic accuracy parameters. When possible, a meta-analysis was performed to calculate the joint sensitivity, specificity, and detection rate for malignancy (with 95% confidence intervals [CIs]), as well as a subgroup analysis based on patient characteristics (antibodies, syndrome). The comprehensive literature search revealed 700 references. Sixteen studies met the inclusion criteria and were ultimately selected. Most of the studies were retrospective (12/16). For the quality assessment, the QUADAS-2 tool was applied to assess the risk of bias. Across 16 studies (793 patients), the joint sensitivity, specificity, and detection rate for malignancy with FDG PET were 0.87 (95% CI: 0.80-0.93), 0.86 (95% CI: 0.83-0.89), and 14.9% (95% CI: 11.5-18.7), respectively. The area under the curve (AUC) of the summary ROC curve was 0.917. Homogeneity of results was observed for sensitivity but not for specificity. Some of the individual studies showed large 95% CIs as a result of small sample size. The results of our meta-analysis reveal high diagnostic performance of FDG PET in the detection of malignancy responsible for PNS, not affected by the presence of onconeural antibodies or clinical

1996-01-01

Subacute paraneoplastic cerebellar degeneration (SPCD) is a cerebellar syndrome associated with an identifiable or occult carcinoma without direct involvement of the nervous system by the cancer. This subacute syndrome is due to an extensive Purkinje cell destruction by anti-Purkinje cells autoantibodies. Some of them are specific for example "anti-YO" antibodies in gynecologic cancer situations. We report the case of a 50-year-old woman who presented an ovarien carcinoma revealed by a SPCD associated to an anti-Purkinje cell autoantibody "anti-YO" and to another unidentified autoantibody. Despite the treatment of the carcinoma, the invaliding SPCD did not regress. The diagnosis of SPCD requires identification and early treatment of the carcinoma, giving the patient the best chances for cure and avoiding major neurologic effects.

Anti-Ma2-associated encephalitis is a rare paraneoplastic neurological syndrome characterized by isolated or combined limbic, diencephalic, or brainstem dysfunction. It is rarely reported in children. We describe the clinical data of a 2-year-old girl referred to our department for refractory focal seizures associated with fever, followed by behavioural changes, speech disturbances and confusional episodes. Brain magnetic resonance imaging (MRI) showed left temporoparietal brain involvement. Haematological, biochemical and infectious evaluations were unremarkable. Autoimmune encephalitis was suspected. Paraneoplastic antibodies tests showed positive results for anti-Ma2 antibodies. Screening for underlying tumour was negative. Immunomodulatory treatment was administrated. The patient showed improvement of vigilance and behaviour. However, she kept refractory epilepsy. Although poor response to immunotherapy, early diagnosis and appropriate treatment of this disorder may prevent irreversible sequelae. Copyright © 2015 European Paediatric Neurology Society.

Digital clubbing as a first clinical presentation of pulmonary metastases in cutaneous melanoma.

PubMed

Tas, Faruk; Erturk, Kayhan

2018-03-01

Digital clubbing is a paraneoplastic phenomenon usually associated with non-small cell lung cancer. We report the development of clubbing in a 49-year old man diagnosed with cutaneous melanoma which had metastasized to the lungs. We also reviewed the literature to understand the association between metastatic melanoma and clubbing. Previous reports of melanoma associated with hypertrophic osteoarthropathy (HOA) are extremely rare; only 7 cases. In all these patients digital clubbing was the main component of the HOA. However, our patient developed digital clubbing in the absence of other features of HOA. Therefore, to our knowledge, our report is the first in the literature. In conclusion, it should be kept in mind that digital clubbing might be associated with metastatic melanoma to the lung, notwithstanding rarely, and successful treatment of the underlying disease is associated with rapid resolution of the clubbing, as occurs in most patients with paraneoplastic syndromes.

Blood gases and plasma electrolytes raise suspicion of this diagnosis and the definitive diagnosis is made by genetic study. Early treatment improves prognosis. The authors present the case of an 11-month-old child with early failure to thrive and severe regurgitation. Blood gases revealed hypochloraemic metabolic alkalosis, hyponatraemia and hypokalaemia. Blood pressure was normal and polyuria was documented. She began therapy with potassium chloride supplementation and indomethacin. There was clinical improvement and plasma potassium and bicarbonate normalised. The molecular study confirmed it was the classic form of Bartter syndrome. Despite being rare in clinical practice, which may lead to unnecessary medical investigation and diagnosis delay, in a child with failure to thrive, hypochloraemic metabolic alkalosis and hypokalaemia, this diagnosis must be considered.

Paraneoplastic limbic encephalitis (PLE) is a rare disorder of the nervous system associated with malignant disease. It has a subacute onset with the following symptoms: cognitive dysfunction, seizures, irritability, hallucinations, and short-term memory loss. Herein, we report the case of a 35-year-old man with PLE, an olfactory neuroblastoma (ONB) admixed with craniopharyngioma, and serum anti-Hu antibodies. The patient presented with generalized seizures, short-term memory loss, and a polypoid mass located high in the nasal cavity. He underwent surgical resection of the tumor and postoperative chemoradiotherapy with concurrent intra-arterial cisplatin administration. Pathological examination indicated an ONB admixed with craniopharyngioma. The patient's neurological symptoms gradually diminished after surgery. No evidence of recurrence was observed during a 4-year follow-up. We reported a histologically unusual heterogeneous tumor that comprised ONB and craniopharyngioma. This is the first reported case of PLE with anti-Hu antibodies possibly associated with ONB admixed with craniopharyngioma.

Waardenburg syndrome is clinically and genetically heterogeneous. The SOX10 mutation related with Waardenburg syndrome type II is rare in Chinese. This study aimed to uncover the genetic causes of Waardenburg syndrome type II in a three-generation family to improve genetic counseling. Complete clinical and molecular evaluations were conducted in a three-generation Han Chinese family with Waardenburg syndrome type II. Targeted genetic counseling was provided to this family. We identified a rare heterozygous dominant mutation c.621C>A (p.Y207X) in SOX10 gene in this family. The premature termination codon occurs in exon 4, 27 residues downstream of the carboxyl end of the high mobility group box. Bioinformatics prediction suggested this variant to be disease-causing, probably due to nonsense-mediated mRNA decay. Useful genetic counseling was given to the family for prenatal guidance. Identification of a rare dominant heterozygous SOX10 mutation c.621C>A in this family provided an efficient way to understand the causes of Waardenburg syndrome type II and improved genetic counseling.

2009-01-01

Several causes of eosinophilic pleural effusions have been described with malignancy being the commonest cause. Hypereosinophilic syndrome (HES) is a rare disease and very few cases have been reported of HES presenting as eosinophilic pleural effusion (EPE). We report a case of a 26-year-old male who presented with shortness of breath. He had bilateral pleural effusions, generalized lymphadenopathy, splenomegaly, and leukocytosis with marked peripheral blood eosinophilia. The pleural fluid was exudative, with 25%–30% eosinophilis, and absence of neoplastic cells. Hypereosinophilic syndrome was diagnosed after other causes of eosinophilia were excluded. He continued to be dyspneic with persistent accumulation of eosinophilic pleural fluid, even after his peripheral eosinophil count had normalized in response to treatment. This patient represents a very unusual presentation of HES with dyspnea and pleural effusions and demonstrates that treatment based on response of peripheral eosinophil counts, as is currently recommended, may not always be clinically adequate.

2012-01-01

Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a rare syndrome characterized by complete or partial agenesis of the uterus and vagina, due to a congenital defect of the Mullerian duct. Affected individuals have a 46,XX karyotype and a normal female phenotype. MRKH syndrome may be isolated (type I MRKH syndrome) or associated with renal, cardiac, and skeletal anomalies, short stature, and auditory defects. The latter is defined as type II MRKH syndrome or the Müllerian duct aplasia/hypoplasia, renal agenesis/ectopy, and cervicothoracic somite dysplasia (MURCS) association. The majority of patients with MRKH syndrome present with primary amenorrhea. We report a case of type II MRKH syndrome who has been referred by a pediatric surgeon for detection of gonadal function. During an inguinal hernia operation, the left ovary had been observed in the hernia sac. Clinical and radiological evaluation of the patient showed an absence of the uterus and left kidney, and cervical hemi vertebra. Based on these findings, the patient was diagnosed as having type II MRKH syndrome.

Raghavan, D Vijaya; Doshi, V Vimal; Nambi, Shanthi

2016-01-01

Joubert syndrome is a rare autosomal recessive disorder with partial or complete agenesis of cerebellar vermis. This syndrome is identified mainly by the presence of molar tooth sign in magnetic resonance imaging of the brain since it has a varied phenotypic presentation. Of the 200 cases reported so far in the literature, only three reports show the presence of autistic symptoms in siblings suggesting a link between the cerebellar vermis and autistic spectrum disorders. In this case report of two siblings, the female child satisfied the criterion for autistic spectrum disorder in accordance with Diagnostic and Statistical Manual of Mental Disorders Fifth Editon. The boy showed developmental delay with autistic features (not amounting to diagnostic threshold). This report is important in that it adds evidence to the literature that abnormalities of cerebellum are involved in the cognitive development and autistic symptoms.

2015-12-01

Pterygoid hamulus syndrome (PHS) is a rare cause of orofacial and oropharyngeal pain. PHS can be associated with a hamulus hypertrophy or with a bursitis of the palatosalpingeus but it has not always an anatomic cause. A 36-year-old woman was seen for a constant posterior palatal pain spreading towards oropharynx, increasing during swallowing and lasting for more than 6 months. Physical examination showed an erythema of the soft palate, medially to the hamulus. Hamulus palpation was painful and revealed hamulus hypertrophia on both sides. A bilateral PHS was evocated. This observation is typical of a PHS. We propose a review of the literature of this little-known syndrome. Treatment is initially conservative (corticosteroids) but surgery can be proposed in case of morphological anomalies of the hamulus. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

In this report, we presented a rare case of bilateral silent sinus syndrome (SSS) in an otherwise healthy 57-year-old man treated with functional endoscopic sinus surgery (FESS). A systematic review of the literature regarding bilateral SSS was performed. A 57-year-old man with well-controlled allergic rhinitis in the absence of previous surgery or trauma presented with bilateral SSS, which was successfully managed with bilateral FESS. A medical literature data base search of the terms "silent sinus syndrome" "maxillary atelectasis," "imploding antrum syndrome," and "bilateral silent sinus syndrome" was performed. The results were then narrowed to include only relevant articles. Relevant articles included three case reports and two articles that describe or mention bilateral SSS. Of the three case reports found, two patients presented with bilateral SSS, whereas the third patient presented metachronously, with the contralateral SSS manifesting 4 months after presentation of the initial ipsilateral SSS. The present literature regarding bilateral SSS is likely incomplete, and further investigation is required to provide greater insight into the prevalence of this disease. In this report, bilateral FESS was successful in resolving symptoms and preventing disease progression.

The 22q11.2 deletion syndrome (22q11DS; velocardiofacial/DiGeorge syndrome; VCFS/DGS; MIM #192430; 188400) is the most common microdeletion syndrome. The phenotypic presentation of 22q11DS is highly variable; approximately 60-75 % of 22q11DS patients have been reported to have a congenital heart defect (CHD), mostly of the conotruncal type, and/or aortic arch defect. The etiology of the cardiac phenotypic variability is not currently known for the majority of patients. We hypothesized that rare copy number variants (CNVs) outside the 22q11.2 deleted region may modify the risk of being born with a CHD in this sensitized population. Rare CNV analysis was performed using Affymetrix SNP Array 6.0 data from 946 22q11DS subjects with CHDs (n = 607) or with normal cardiac anatomy (n = 339). Although there was no significant difference in the overall burden of rare CNVs, an overabundance of CNVs affecting cardiac-related genes was detected in 22q11DS individuals with CHDs. When the rare CNVs were examined with regard to gene interactions, specific cardiac networks, such as Wnt signaling, appear to be overrepresented in 22q11DS CHD cases but not 22q11DS controls with a normal heart. Collectively, these data suggest that CNVs outside the 22q11.2 region may contain genes that modify risk for CHDs in some 22q11DS patients.

Ectopic production of beta-HCG by a maxillary squamous cell carcinoma.

Paraneoplastic syndromes of the head and neck are rare. Hypercalcemia and leukocytosis have been described. The literature was reviewed, and a case of a squamous cell carcinoma of the maxilla producing beta human chorionic gonadotropin (beta-HCG) is presented. A 47-year-old white man with a T4N1M0 squamous cell carcinoma of the left maxilla was treated with a maxillectomy and neck dissection for an N1 positive neck. After completing his planned radiotherapy, he developed distant metastases, which included an axillary node that stained positive for human beta-HCG. Retrospective review of the primary specimen showed beta-HCG positivity in an anaplastic component of the tumor along with vascular invasion. The first case in the literature of a paraneoplastic syndrome with beta-HCG production in association with squamous cell carcinoma of the maxilla is presented. This case history fits the aggressive nature of beta HCG producing tumors elsewhere in the body.

Voltage gated potassium channel antibodies (VGKC Abs) are known to cause three rare neurological syndromes- neuromyotonia, Morvan's syndrome and limbic encephalitis although an increasing array of other associated neurological symptoms are becoming recognised. The authors describe the case of a 60-year-old female who presented to the neurology clinic with an apparent early onset dementing process. She was noted to have both extrapyramidal and frontal release signs on examination and was admitted for further evaluation. Her dementia investigation including a neoplastic screen was negative except for VGKC antibody positivity. Her symptoms dramatically improved with commencement of immunosuppression. A non-paraneoplastic VGKC antibody associated dementia-like syndrome has rarely been described. The authors add to the few existing reports of what represents an important reversible cause of cognitive impairment.

Treatment decisions in a man with Hodgkin lymphoma and Guillian-Barré syndrome: a case report.

Hughes, Caren L; Yorio, Jeffrey T; Kovitz, Craig; Oki, Yasuhiro

2014-12-21

Guillain-Barre syndrome, or acute inflammatory demyelinating polyneuropathy, has been described in the presence of malignancies such as lymphoma. Guillain-Barre syndrome/acute inflammatory demyelinating polyneuropathy causes paresthesias and weakness, which can make the treatment of lymphoma with chemotherapy challenging. Given the rarity of this co-presentation it is not known if the effects of Guillain-Barre syndrome should be considered when selecting a treatment regimen for Hodgkin lymphoma. To the best of our knowledge, the impact of these treatment modifications has not been previously reported. We report the case of a 37-year-old Caucasian man with a diagnosis of stage IIB classical Hodgkin lymphoma with concomitant Guillain-Barre syndrome. Our patient originally presented with an enlarged cervical lymph node and quickly developed distal paresthesia and progressive weakness of all four extremities. He was diagnosed with Hodgkin's lymphoma and initiated on treatment with doxorubicin, bleomycin, vinblastine, and dacarbazine. Doses of bleomycin and vinblastine were held or dose-reduced throughout his initial treatment course due to underlying neuropathy and dyspnea. He continued to have persistent disease after five cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine and went on to receive salvage treatments including more chemotherapy, radiation, autologous stem cell transplant and is currently preparing for an allogeneic stem cell transplant. Paraneoplastic syndromes such as Guillain-Barre syndrome/acute inflammatory demyelinating polyneuropathy can make the treatment of patients with Hodgkin lymphoma more challenging and can interfere with delivering full-dose chemotherapy. Further case series are needed to evaluate the effect that paraneoplastic syndromes, or adjustments made in therapy due to these syndromes, negatively affect the prognosis of patients with Hodgkin lymphoma.

2015-01-01

Behcet's disease is a multisystemic vasculitis of unknown etiology with a chronic relapsing course. Vasculitis in Behcet's disease with predominant vascular involvement is the only vasculitis that affects both arteries and veins of any size. Involvement of the renal artery and inferior vena cava is rare among the arteries and veins, respectively. When disease affect the veins, it is in the form of thrombosis. Arterial complications include aneurysms, stenosis and occlusions. Both rupture of arterial aneurysm and occlusion of suprahepatic veins, causing Budd-Chiari syndrome, are associated with a high mortality rate. Vascular involvement is more common in male patients than in female patients. Men and patients with a younger age of onset present with a more severe prognosis. In this case report, we describe a very rare cause of intrarenal arterial aneurysm's rupture with previous Budd-Chiari syndrome due to Behcet's disease and successful angiographic embolization of actively bleeding aneurysm.

Moyamoya disease is a rare cerebrovascular anomaly involving the intracranial carotid arteries that can present clinically with either ischemic or hemorrhagic disease. Moyamoya syndrome, indistinguishable from moyamoya disease at presentation, is associated with multiple clinical conditions including neurofibromatosis type 1, autoimmune disease, prior radiation therapy, Down syndrome, and Turner syndrome. We present the first reported case of an adult patient with previously unrecognized mosaic Turner syndrome with acute subarachnoid and intracerebral hemorrhage as the initial manifestation of moyamoya syndrome. A 52-year-old woman was admitted with a subarachnoid hemorrhage with associated flame-shaped intracerebral hemorrhage in the left frontal lobe. Physical examination revealed short stature, pectus excavatum, small fingers, micrognathia, and mild facial dysmorphism. Cerebral angiography showed features consistent with bilateral moyamoya disease, aberrant intrathoracic vessels, and an unruptured 4-mm right superior hypophyseal aneurysm. Genetic analysis confirmed a diagnosis of mosaic Turner syndrome. Our case report is the first documented presentation of adult moyamoya syndrome with subarachnoid and intracerebral hemorrhage as the initial presentation of mosaic Turner syndrome. It illustrates the utility of genetic evaluation in patients with cerebrovascular disease and dysmorphism. Copyright © 2014 National Stroke Association. Published by Elsevier Inc.

Patient: Female, 78 Final Diagnosis: Cerebral hyperperfusion syndrome Symptoms: — Medication: — Clinical Procedure: Endovascular embolectomy Specialty: Neurology Objective: Unknown ethiology Background: Cerebral hyperperfusion syndrome (cHS) is a well known but rare complication after carotid endarterectomy, carotid angioplasty with stenting, and stenting of intracranial arterial stenosis. The clinical presentation may vary from acute onset of focal oedema (stroke-like presentation) and intracerbral hemorrhage to delayed (>24h hours after the procedure) presentation with seizures, focal motor weakness, or late intracerebral hemorrhage. The incidence of cHS after carotid endarterectomy ranges from 0–3% and defined as an increase of the ipsilateral cerebral blood flow up to 40% over baseline in ultrasound. Case Report: We present a case of a 78-year-old woman with an acute ischemic stroke due to left side middle cerebral artery territory with right sided hemiparesis and aphasia (NIHSS 16). After systemic thrombolysis embolectomy using a retractable stent (Solitaire® device) was performed and resulted in complete and successful recanalization of MCA including its branches about 210 minutes after symptom onset but, partial dislocation of thrombotic material into the anterior cerebral artery (ACA). Conclusions: Cerebral hyperperfusion syndrome should be considered in patients with clinical deterioration after successful recanalisation and the early diagnosis and treatment may be important for neurological outcome after endovascular embolectomy PMID:24340127

To extend nursing knowledge of distress experienced by family caregivers of children with rare genetic disorders, by exploring the perspectives of caregivers of children with Russell-Silver Syndrome in Taiwan. Caring for a child with a rare genetic disorder often has profound effects on families, especially when diagnosis and treatment is complex or not yet well developed, such as that in Russell-Silver Syndrome (or Silver-Russell syndrome). This disorder causes dwarfism and developmental difficulties, requiring long-term care planning. Previous research has focused mostly on medical care, but little is known about families' perspectives of caring difficulties, the help they need and nursing care required. An exploratory qualitative approach was used to inform this study. Family caregivers, whose children were undergoing medical care in a leading Taiwan medical centre, were invited to participate in face-to-face, in-depth interviews. Data were analysed by content analysis. Fifteen caregivers including 11 mothers, two fathers and two grandmothers participated. Five major themes and 13 sub-themes of care-giving distress were identified: endless psychological worries; the lengthy process to confirm a medical diagnosis; adjustment efforts in modifying family roles; dilemmas in deciding between Western or Chinese traditional medicine; and negative responses to society's concerns. Their primary sources of support were spouses, parents and health professionals, accordingly. Complex physio-psycho-social and decision-making distress in caring for children with a rare genetic disorder were systematically revealed from the perspectives of ethnic-Chinese family caregivers. Long-term care plans for children with a rare genetic disorder such as Russell-Silver Syndrome need to focus on positive dynamic family interactions, life-stage development and family caregiver support. Research on care-giving in rare genetic disorders is also warranted across cultures and countries to

There is a broad range of possible diagnoses for an elevated beta human chorionic gonadotropin (β-hCG) in the absence of intrauterine or ectopic pregnancy. When women of child bearing potential undergo evaluation for clinical trial, it is often unclear what course of evaluation to take when a pregnancy test is positive. We describe the clinical course of a patient with widely metastatic mucinous ovarian carcinoma with metastasis to the peritoneum, lymph nodes and liver. The patient was found to have a mildly elevated β-hCG during initial evaluation for clinical trial. Extensive work up for ectopic pregnancy, trophoblastic disease, and phantom β-hCG were negative. The patient's β-hCG levels continued to rise until initiation of therapy. She was treated on a phase I protocol with restaging scans revealing a partial response. The β-hCG was retested and declined in conjunction with her response, consistent with paraneoplastic β-hCG. Here, we propose a decision making algorithm to evaluate a patient with an elevated β-hCG undergoing assessment for clinical trial.

Patients with rare and ultra-rare diseases make heavy demands on the resources of both health and social services, but these resources are often used inefficiently due to delays in diagnosis, poor and fragmented care. We analysed the national service for an ultra-rare disease, Alstrom syndrome, and compared the outcome and cost of the service to the standard care. Between the 9th and 26th of March 2014 we undertook a cross-sectional study of the UK Alstrom syndrome patients and their carers. We developed a semi-structured questionnaire to assess our rare patient need, quality of care and costs incurred to patients and their careers. In the UK all Alstrom syndrome patients are seen in two centres, based in Birmingham, and we systematically evaluated the national service and compared the quality and cost of care with patients' previous standard of care. One quarter of genetically confirmed Alstrom syndrome UK patients were enrolled in this study. Patients that have access to a highly specialised clinical service reported that their care is well organised, personalised, holistic, and that they have a say in their care. All patients reported high level of satisfaction in their care. Patient treatment compliance and clinic attendance was better in multidisciplinary clinic than the usual standard of NHS care. Following a variable costing approach based on personnel and consumables' cost, our valuation of the clinics was just under £700/patient/annum compared to the standard care of £960/patient/annum. Real savings, however, came in terms of patients' quality of life. Furthermore there was found to have been a significant reduction in frequency of clinic visits and ordering of investigations since the establishment of the national service. Our study has shown that organised, multidisciplinary "one stop" clinics are patient centred and individually tailored to the patient need with a better outcome and comparable cost compared with the current standard of care for rare

A rare fatality due to calcified stylohyoid ligament (Eagle syndrome).

The elongation or calcification of the stylohyoid ligament that leads to pressure symptoms, or entrapment of nearby glossopharyngeal nerve or carotid artery, is known as Eagle syndrome. A PubMed search leads to finding of rare fatality among the 49 reported cases. In the present case, the deceased was a 40-year-old male who choked on his food. We hypothesise that the impaction of food in the upper respiratory tract, as well as the inability to intubate the person, were both the result of the calcified stylohyoid ligament.

Paraneoplastic Scleroderma: Are There Any Clues?

PubMed

Jedlickova, Hana; Durčanská, Veronika; Vašků, Vladimír

2016-04-01

Dear Editor, Scleroderma associated with neoplasia is rare, with only a small number of cases reported. We describe 4 patients with paraneoplastic scleroderma who were treated at the I. Department of Dermatovenereology, St. Anna Hospital, during the period between 2004 and 2014. The patients were diagnosed with cholangiogenic carcinoma, endometrial carcinoma, prostatic adenocarcinoma, and adenoma of the suprarenal gland. In the case of concurrent scleroderma and tumor, four situations may occur: they can develop independently of each other; scleroderma may be induced by the tumor; the tumor can develop in the scleroderma; or the tumor can be induced by immunosuppressive therapy. Sclerotization of the skin was described in association with lung cancer, carcinoid, plasma cell dyscrasia, cancer of the ovary, cervix, breast, esophagus, stomach, nasopharynx, melanoma, and sarcoma (1,2,5,7,10). Symptoms may be induced by substances secreted by the tumor (hormones, cytokines, etc.) (9). Tumorous cells further induce cytotoxic and autoantibody response. Scleroderma is characterized by immunological dysregulation, vasculopathy, and hyperproduction of the extracellular matrix by activated fibroblasts. Endothelial, inflammatory, and mesenchymal cells produce cytokines, chemokines, and growth factors e.g. Interleukin-1 (IL1), Interleukin-6 (IL6), tumor necrosis factor alpha (TNF α), collagen alpha 1, connective tissue growth factor (CTGF) (3), and basic fibroblast growth factor (bFGF). This factor is also produced by lung cancer cells (4). The clinical picture of scleroderma and paraneoplastic scleroderma is similar. Diffuse thickening of the skin and/or sclerodermatous plaques can be seen. The histological picture is consistent with scleroderma. Capillaroscopy changes, antinuclear antibodies (ANA), sclerodactyly, and Raynaud phenomenon suggest the diagnosis of systemic scleroderma (SS) (4). Our patients did not fulfill enough of the criteria for SS. Both diffuse and

To describe the clinical and laboratory features and outcome of 6 patients presenting with remitting seronegative symmetrical synovitis with pitting edema (RS3PE) revealing a solid tumor. Patients with RS3PE who presented with a solid tumor and who had been seen between January 1, 1994, and December 31, 1996, were included in a retrospective multicenter analysis. These patients fulfilled McCarty's description of RS3PE and the following criteria: (1) bilateral pitting edema of both hands, (2) sudden onset of polyarthritis, (3) age >50 years, and (4) absence of rheumatoid factor (RF). Six male patients with RS3PE are described, of mean age 74 years (range 72-78), presenting prostatic (n = 4), gastric (n = 1), and colic (n = 1) adenocarcinomas. The clini cal picture was characterized by the classical form of RS3PE syndrome and by a deterioration in general condition, sometimes with fever. All patients were negative for RF and antinuclear antibodies. In 2 cases of prostatic adenocarcinoma serum levels of interleukin 6 (IL-6) were high, but decreased with treatment. In these 6 patients, the articular manifestations regressed totally or partially in response to corticosteroids, sometimes at low doses, associated in most cases with specific antitumoral therapy. None displayed erosion or distal bone destruction. The mean survival following discovery of RS3PE was 11 months (range 6-18), 5 patients dying of metastatic dissemination of their cancer and the 6th of myocardial infarction. RS3PE is a heterogeneous syndrome that can reveal a solid tumor, notably an adenocarcinoma. There exist no specific criteria to define its forms, but this syndrome should be kept in mind in the face of a deterioration in general health. Although the pathogenic mechanism is unknown, this could involve a type of paraneoplastic polyarthritis linked to the synthesis of a factor such as IL-6.

We report a 40-year-old man with severe hypokinesis as paraneoplastic manifestation of a microscopic "carcinoma in situ" of the testis. The young age of the patient, along with progressive neurologic deterioration, detection of anti-Ma2 antibodies, and ultrasound findings of bilateral microcalcifications, led to bilateral orchiectomy, revealing the tumor in both testes. After orchiectomy, neurological symptoms stabilized, but the patient eventually died of systemic complications caused by his severe neurological deficits. Anti-Ma2 paraneoplastic encephalitis should be considered in patients with severe hypokinesis, and intensive investigation and aggressive approach to treatment is encouraged to prevent progression of the neurological deficits.

Ewing's sarcoma is a common malignant bone tumour presenting in children and young adults. Rarely extra- skeletal soft tissues and visceral organs can also be the site of origin of Ewing's sarcoma. Primary pulmonary Ewing's sarcoma is an extremely rare malignancy which occurs in the paediatric population. We report an unusual case of primary pulmonary Ewing's sarcoma in a nine year old girl who presented with features of superior vena cava syndrome in the emergency department. The diagnosis was confirmed pathologically both by light microscopy and immunohistochemistry. The patient was put on chemotherapy and surgery was planned but the patient expired within three days of starting chemotherapy.

Patients with cancer may develop paraneoplastic neurological syndromes (PNS) in which onconeural antibodies are important diagnostic findings. As the functional role of onconeural antibodies is largely unknown, insight gained by identifying associated antibodies may help to clarify the pathogenesis of the PNS. In this study, we identified patients with Yo antibodies who also had antibodies to an uncharacterized protein called coiled-coil domain-containing protein 104 (CCDC104). We found a significant association between CCDC104 and Yo antibodies (4 of 38, 10.5%), but not other onconeural antibodies (0 of 158) (P = 0.007, Fisher's exact test). The prevalence of CCDC104 antibodies was approximately similar in patients with cancer (8 of 756, 1.1%) and in healthy blood donors (2 of 300, 0.7%). CCDC104 antibodies were not associated with PNS, as this was found in only two of the ten CCDC104-positive patients. The CCDC104 protein, whose function is unknown, is expressed in various human tissues, including the brain, and is localized mainly to the nucleus, but is also found in the cytoplasm. The association between Yo and CCDC104 antibodies may indicate functional similarities.

[Anti-Ma2-associated encephalitis and paraneoplastic limbic encephalitis].

PubMed

Yamamoto, Tomotaka; Tsuji, Shoji

2010-08-01

Anti-Ma2-associated encephalitis (or anti-Ma2 encephalitis) is a paraneoplastic neurological syndrome (PNS) characterized by isolated or combined limbic, diencephalic, or brainstem dysfunction. Anti-Ma2 antibodies detected in the serum or cerebrospinal fluid of patients are highly specific for this disease entity and belong to a group of well-characterized onconeuronal antibodies (or classical antibodies). The corresponding antigen, Ma2 is selectively expressed intracellularly in neurons and tumors as is the case with other onconeuronal antigens targeted by classical antibodies. However, in most cases the clinical pictures are different from those of classical PNS and this creates a potential risk of underdiagnosis. Although limbic dysfunction is the most common manifestation in patients with anti-Ma2 encephalitis which is one of the major causes of paraneoplastic limbic encephalitis (LE), it has been reported that less than 30% of the patients with anti-Ma2 LE exhibit clinical presentations typical of the classical description of LE. Of the remaining, many exhibit excessive daytime sleepiness, vertical ophthalmoparesis, or both associated with LE, because of frequent involvement of the diencephalon and/or upper brainstem. Anti-Ma2 LE can also be manifested as a pure psychiatric disturbance such as obsessive-compulsive disorder in a few cases. Some patients develop mesodiencephalic encephalitis with minor involvement of the limbic system, and some may manifest severe hypokinesis. About 40% of the patients with anti-Ma2 antibodies also have antibodies against different epitopes on Ma1, a homologue of Ma2. These patients may have predominant cerebellar and/or brainstem dysfunctions due to more extensive involvement of subtentorial structures. Anti-Ma2 encephalitis is outstanding among other PNS associated with classical antibodies in that the response rate to treatment is relatively high. While it can cause severe neurological deficits or death in a substantial

Paraneoplastic hypertrophic osteopathy (pHO) is known to occur in both canine and human cancer patients. While the pathology of pHO is well-described in the dog, very little information exists regarding the true clinical presentation of dogs affected with pHO. The primary objective of this study was to provide a more comprehensive clinical picture of pHO. To this end, we retrospectively identified 30 dogs and recorded data regarding presenting complaints and physical examination (PE) findings on the date of pHO diagnosis. As a secondary objective, any blood test results were also collected from the computerized records. The most common clinical signs included leg swelling, ocular discharge and/or episcleral injection, lameness, and lethargy. The most common haematological and serum biochemical abnormalities included anaemia, neutrophilia and elevated alkaline phosphatase. In addition to presenting a more detailed clinical description of pHO in the dog, these data support the previously described haematological, serum biochemical and PE abnormalities published in individual case reports.

We report two cases of paraneoplastic remitting seronegative symmetrical synovitis with pitting edema (RS3PE) associated with prostatic adenocarcinoma. One of the patients was positive for Helicobacter pylori and the other had secondary bone metastases. In the latter, the clinical picture of RS3PE developed after surgical intervention for the primary lesion. On physical examination, while the hands and feet were swollen in the first patient, pitting edema was present only at the feet of the other. All joints of the affected hands and feet were painful. Serological tests including rheumatoid factor, antinuclear antibody, and human leukocyte antigen B27 were all negative. Response to low-dose corticosteroid treatment was delayed in the first patient, but the symptoms were relieved better in the second one.

Anaplastic transformation of differentiated thyroid carcinoma (DTC) is a rare event with a poor clinical outcome. It usually occurs in the primary site or in regional lymph nodes, but rarely in distant metastatic lesions. A 55-year-old woman with persistent pain in the left hip joint visited our hospital. She had a history of DTC that had been surgically removed 12 years earlier. Clinical images showed a tumorous mass in the left pelvis, indicative of bone metastasis. The patient underwent surgery to remove the tumor and remained stable until local recurrence was found 5 weeks after the surgery. The patient subsequently underwent radiation therapy; however, she died of respiratory failure due to lung metastases 2 months after the surgery for the recurrent lesion. The surgical specimens were diagnosed as anaplastic thyroid carcinoma, indicating that anaplastic transformation of thyroid follicular carcinoma occurred in the metastatic skeletal lesion. In addition, the patient had an unusually high white blood cell count throughout the course. Based on elevated serum granulocyte colony-stimulating factor (G-CSF) levels and positive immunostaining for G-CSF in the surgical specimens, the patient was diagnosed with paraneoplastic leukocytosis. To our knowledge, this is the first case of anaplastic transformation of DTC arising in a metastatic bone lesion described in the literature. In addition, the present case also exhibited severe leukocytosis accompanied by elevated serum G-CSF levels. Clinicians should be aware of the possibility of this occurring in their patients with DTC, as this development calls for a rapid change from observational follow-up to aggressive treatment.

Here we present, to the best of our knowledge, the first case of a paraneoplastic Cushing's syndrome (hypercortisolism) resulting from treatment-related neuroendocrine prostate cancer - a highly aggressive and difficult disease to treat. A 51-year-old man was started on androgen deprivation therapy after presenting with metastatic prostate cancer, characterized by diffuse osseous metastasis. Shortly thereafter, he developed progressive disease with biopsy proven neuroendocrine prostate cancer as well as symptoms of increased skin pigmentation, hypokalemia, hypertension, hyperglycemia and profound weakness, consistent with ectopic Cushing's syndrome. Molecular analysis of the patient's tumor through RNA sequencing showed high expression of several genes including CHGA, ASCL1, CALCA, HES6, PCSK1, CALCB and INSM1 confirming his neuroendocrine phenotype; elevated POMC expression was found, supporting the diagnosis of ectopic Cushing's syndrome. © 2016 The Japanese Urological Association.

Sinonasal phosphaturic mesenchymal tumor: Case report and systematic review

2014-01-01

We report a case of sinonasal phosphaturic mesenchymal tumor (PMT) and conduct a systematic review of the literature to highlight a unique paraneoplastic syndrome associated with PMT. We used English language publications from Medline and Cochrane databases (1970–2013) as data sources. A systematic review of the literature was conducted. All reported cases of head and neck PMTs were included. The presence or absence of the associated paraneoplastic syndrome was noted. We found 33 cases of PMT in the head and neck reported in the literature, 17 of which occurred in the sinonasal area. Approximately 5% of all PMTs are located in the head and neck. Just greater than half are concentrated in the sinonasal area, and the remaining involve various bony and soft tissue structures of the head and neck. PMT is sometimes associated with a paraneoplastic syndrome of tumor-induced (oncogenic) osteomalacia (TIO) causing bone pain, muscle weakness, and pathologic fractures. We present the 18th reported case of sinonasal PMT. A smooth mucosa-covered midline intraseptal mass filling the posterior nasal cavity with destruction and erosion of the skull base was found in an adult male. The patient underwent successful endoscopic resection with wide negative margins and is without recurrence at 24-month follow-up. PMT is a benign, locally aggressive tumor with rare malignant transformation. Knowledge of the bony invasion and destruction caused by this tumor is essential in planning surgical resection with wide negative margins. Familiarity with the associated TIO is essential to investigate for and manage any associated bony morbidity. PMID:25565053

Multiple autoimmune syndrome (MAS), an extreme phenotype of autoimmune disorders, is a very well suited trait to tackle genomic variants of these conditions. Whole exome sequencing (WES) is a widely used strategy for detection of protein coding and splicing variants associated with inherited diseases. The DNA of eight patients affected by MAS [all of whom presenting with Sjögren's syndrome (SS)], four patients affected by SS alone and 38 unaffected individuals, were subject to WES. Filters to identify novel and rare functional (pathogenic-deleterious) homozygous and/or compound heterozygous variants in these patients and controls were applied. Bioinformatics tools such as the Human gene connectome as well as pathway and network analysis were applied to test overrepresentation of genes harbouring these variants in critical pathways and networks involved in autoimmunity. Eleven novel and rare functional variants were identified in cases but not in controls, harboured in: MACF1, KIAA0754, DUSP12, ICA1, CELA1, LRP1/STAT6, GRIN3B, ANKLE1, TMEM161A, and FKRP. These were subsequently subject to network analysis and their functional relatedness to genes already associated with autoimmunity was evaluated. Notably, the LRP1/STAT6 novel mutation was homozygous in one MAS affected patient and heterozygous in another. LRP1/STAT6 disclosed the strongest plausibility for autoimmunity. LRP1/STAT6 are involved in extracellular and intracellular anti-inflammatory pathways that play key roles in maintaining the homeostasis of the immune system. Further; networks, pathways, and interaction analyses showed that LRP1 is functionally related to the HLA-B and IL10 genes and it has a substantial impact within immunological pathways and/or reaction to bacterial and other foreign proteins (phagocytosis, regulation of phospholipase A2 activity, negative regulation of apoptosis and response to lipopolysaccharides). Further, ICA1 and STAT6 were also closely related to AIRE and IRF5, two very

Autoimmune lymphoproliferative syndrome (ALPS) is a prototypic disorder of impaired apoptosis characterized by autoimmune features and lymphoproliferation. Heterozygous germline or somatic FAS mutations associated with preserved protein expression have been described. Very rare cases of homozygous germline FAS mutations causing severe autosomal recessive form of ALPS with a complete defect of Fas expression have been reported. We report two unrelated patients from highly inbred North African population showing a severe ALPS phenotype and an undetectable Fas surface expression. Two novel homozygous mutations have been identified underlying rare splicing defects mechanisms. The first mutation breaks a branch point sequence and the second alters a regulatory exonic splicing site. These splicing defects induce the skipping of exon 6 encoding the transmembrane domain of CD95. Our findings highlight the requirement of tight regulation of FAS exon 6 splicing for balanced alternative splicing and illustrate the importance of such studies in highly consanguineous populations.

Visual disturbances in advanced cancer patients are very rarely signaled, evaluated, or adequately treated. The main causes of sight disturbances are primary eye tumors, ocular metastases, and some paraneoplastic syndromes. Sight alteration can also be associated with asthenia, fatigue, anemia, and hypovitaminosis. These symptoms can be monocular or binocular, and their gravity and evolution can vary. Based on a survey of 156 patients, we estimate the prevalence of visual disturbances to be 12% in advanced cancer patients.

Hypothyroid myopathy is observed frequently and the resolution of the clinical manifestations of myopathy following thyroid hormone replacement is well known. However, a specific subtype of hypothyroid myopathy, Hoffmann's syndrome, characterized by increased muscular mass (pseudohypertrophy), proximal muscle weakness, muscle stiffness and cramps, is rarely reported. Herein, we describe a 34-year-old male who presented with proximal muscle weakness and non-pitting edema of the lower extremities. He initially visited the neurology department where he was suspected of having polymyositis. Additional laboratory evaluation revealed profound autoimmune hypothyroidism and elevated muscle enzymes including creatine kinase. The patient was started on levothyroxine treatment and, subsequently, clinical symptoms and biochemical parameters resolved with the treatment. The present case highlights that hypothyroidism should be considered in the differential diagnosis of musculoskeletal symptoms even in the absence of overt manifestations of hypothyroidism. To our knowledge, this is the first case reported in Korea. PMID:26394732

Lemierre's syndrome is a rare complication of acute pharyngitis characterised by septicaemia with infective thrombophlebitis of the internal jugular vein, most commonly due to Fusobacterium necrophorum. It characteristically affects healthy young adults causing persistent pyrexia and systemic sepsis presenting several days after an initial pharyngitis. Septic emboli seed via the bloodstream to distant sites including the lung, joints, skin, liver, spleen and brain. Prolonged antimicrobial therapy is required and admission to intensive care common. This once rare condition is increasing in incidence but awareness amongst clinicians is low. We present a classic case in a young man who developed multi-organ failure requiring intensive care support and describe the epidemiology, pathophysiology, microbiology, clinical features and management of the disease.

2017-03-06

BACKGROUND The etiology of deep venous thrombosis (DVT) may pose a significant diagnostic challenge because truly reversible causes of DVT are rare. In this regard, known pelvic anatomic abnormalities such as aortic and iliac aneurysms should be seriously considered as a complicating factor in patients presenting with acute DVT so as not to miss a potentially curable etiology of May-Thurner syndrome (MTS). CASE REPORT We report the case of a 69-year-old man with a known abdominal aortic aneurysm and bilateral iliac artery aneurysms who presented with an acute DVT. A computed tomography scan of the abdomen and pelvis showed increased dilation of his aneurysmal disease with new resultant compression of the left iliac vein representing acquired MTS. The patient underwent endovascular aneurysm repair of the infra-renal abdominal aortic aneurysm and right common iliac artery aneurysm with a Gore Excluder endoprosthesis in lieu of venous stenting, with resolution of symptoms. CONCLUSIONS Infra-renal aortic and iliac aneurysms causing MTS are extremely rare, and patients at risk for MTS through these mechanisms do not fit the classical demographics associated with this syndrome. Furthermore, this is the first case described in which MTS was treated by addressing the aneurysm through an endoprosthetic approach instead of venous stenting, which is the conventional intervention for MTS.

2013-01-01

Ulerythema ophryogenes (also known as keratosis pilaris atrophicans faciei) is a rarely reported cutaneous manifestation of Noonan syndrome. Recognizing ulerythema ophryogenes as a cutaneous association in Noonan syndrome may aid in the diagnosis of this relatively common genetic condition. We present a case of a patient with Noonan syndrome and ulerythema ophryogenes associated with a SOS1 mutation and review the literature on this association. To the best of our knowledge, this is the second case of Noonan syndrome proven to be due to an SOS1 mutation in which ulerythema ophryogenes was clinically recognized and specifically diagnosed. The presence of ulerythema ophryogenes in a patient with Noonan syndrome increases the likelihood of a SOS1 mutation. Further reports by dermatologists and medical geneticists documenting ulerythema ophryogenes and not just descriptions of sparse or absent eyebrows will help support this genotype-phenotype correlation.

Esophageal perforation is the fastest progressing and the most life-threatening disruption of gastrointestinal tract continuity. It must be regarded as an emergency condition that requires early diagnosis as well as very aggressive and rapid implementation of treatment in order to avoid serious complications and death. Methods of treatment for spontaneous esophageal perforation continue to be a matter of controversy. However, all authors emphasize that ultimate success depends largely on the time taken to establish the diagnosis. The authors of this study describe a rare case of duodenal ulcer perforation accompanied by Boerhaave syndrome. PMID:26702287

"Serpentine-like syndrome" is a severe and rare association of multiple congenital malformations, characterised by brachioesophagus, secondary intrathoracic stomach, and vertebral anomalies. Other associated anomalies have been described, such as malposition and herniation of abdominal organs. We report the natural history of a baby girl born at 29 weeks of gestation with intra uterine growth restriction, short neck, large rachischisis from cervical to thoracic spine, a very short oesophagus, thoracic stomach associated with a midline diaphragmatic hernia, malrotated gut and median cleft lip. Most of these anomalies were detected antenatally. Molecular karyotype was normal. She died at age 12 days. To our knowledge, the present patient represents the 8th report of a case of "Serpentine-like syndrome". Brachioesophagus and congenital vertebral anomalies, in particular rachischisis, are the cardinal features of this condition. All reported cases have been sporadic and the cause is still unknown. We believe that the specificity of the presentation as well as the similarities between available descriptions of patients suggests a common, yet to identify, molecular cause, possibly involving a developmental "toolkit"/homeobox gene or related pathways.

The Budd-Chiari syndrome (BCS) is a rare disorder due to chronic liver disease (CLD), which is caused by the obstruction of hepatic venous outflow that can be located at any place from the small hepatic venules up to the entrance of the inferior vena cava (IVC) into the right atrium. Among the causes of BCS, the rarer one is coagulation factor deficiencies. Here, we report a case of BCS associated with deficiency of protein C resulting in thrombus in IVC. The patient was a 50-year-old male, who had been suffering from recurrent abdominal and leg swelling for a long period of 7 years. He was evaluated thoroughly, and other causes of liver cirrhosis were excluded. Begum R, Al Mahtab M, Al Mamun A, Moben AL, Hossain SMS, Das DC, Malakar D, Rashid HO, Roy PP, Rahman S.

Barone, Daniel A; Krieger, Ana C

2016-05-01

Voltage-gated potassium channels (VGKCs) are a family of membrane proteins responsible for controlling cell membrane potential. The presence of antibodies (Ab) against neuronal VGKC complexes aids in the diagnosis of idiopathic and paraneoplastic autoimmune neurologic disorders. The diagnosis of VGKC Ab-associated encephalopathy (VCKC Ab syndrome) should be suspected in patients with subacute onset of disorientation, confusion, and memory loss in the presence of seizures or a movement disorder. VGKC Ab syndrome may present with sleep-related symptoms, and the purpose of this communication is to alert sleep and neurology clinicians of this still-under-recognized condition. In this case, we are presenting the VGKC Ab syndrome which improved after treatment with solumedrol. The prompt recognition and treatment of this condition may prevent the morbidity associated with cerebral atrophy and the mortality associated with intractable seizures and electrolyte disturbances.

2013-01-17

Kallmann syndrome (KS) is a genetically heterogeneous and rare disorder characterised by the combination of hypothalamic hypogonadism and anosmia/hyposmia, a variable degree of intellectual disability and several somatic anomalies. In about one-third of the patients, mutations have been identified in at least seven different genes. Virtually no data are available about possible neuropsychiatric symptoms in KS. Here, a young adult male is described with a previous clinical diagnosis of KS and recent paranoid schizophrenia of which positive, but not negative symptoms, fully remitted upon treatment with antipsychotics. Neither genome-wide array analysis nor mutation analyses disclosed imbalances or mutations in any of presently known KS disease genes. This is the first report on a patient with KS and paranoid schizophrenia in whom extensive genetic analyses were performed. It is concluded that further studies are warranted in order to elucidate a possible increased risk for psychiatric symptoms in patients with KS.

Sweet's syndrome (SS) is a neutrophilic dermatosis disorder of unknown aetiology, characterised by acute fever, neutrophilia, painful erythematous papules, nodules and plaques, and an infiltrate consisting predominantly of mature neutrophils in the upper dermis. Classical SS is a rare extra-intestinal manifestation of inflammatory bowel disease (IBD). It is more common in Crohn's disease than in ulcerative colitis (UC). There is a predilection for women, and for patients with colonic disease and active IBD. We report the case of a 39-year-old woman with a flare of moderate severity UC treated with mesalazine who presented with a 5-day history of acute fever, painful papules and plaques on forearms and legs, episcleritis and cervical pain. Skin biopsies showed papillary dermis inflammatory cell infiltration composed mainly of neutrophils, without evidence of leukocytoclastic vasculitis or panniculitis, compatible with SS. The patient had an excellent response to systemic corticosteroids. Symptoms promptly improved and skin lesions resolved after 7 weeks. 2016 BMJ Publishing Group Ltd.

Waardenburg syndrome (WS) is a rare disorder comprising sensorineural deafness and pigmentation abnormalities. Four distinct subtypes are defined based on the presence or absence of additional symptoms. Mutations in six genes have been described in WS. SOX10 mutations are usually associated with a more severe phenotype of WS with peripheral demyelinating neuropathy, central dysmyelinating leukodystrophy, and Hirschsprung disease. Here we report a 32-year-old man with a novel heterozygous missense variant in SOX10 gene, who presented with congenital deafness, Hirschsprung disease, iris heterochromia, foot deformity, and intermediate conduction velocity length-dependent sensorimotor neuropathy. This case highlights that the presence of other non-neuropathic features in a patient with presumed hereditary neuropathy should alert the clinician to possible atypical rare causes. © 2017 Peripheral Nerve Society.

Cardiovascular disease (CVD) presents the most serious health problems and contributes to the increased mortality in young women with Turner syndrome. Arterial hypertension in Turner syndrome patients is significantly more prevalent than that in a general age-matched control group. The aetiology of hypertension in Turner syndrome varies, even in the absence of cardiac anomalies and obvious structural renal abnormalities. Pheochromocytoma is an extremely rare cause among various etiologies for hypertension in patients with Turner syndrome. Here, we reported a pheochromocytoma as a rare cause of hypertension in Turner syndrome patient. A 21-year-old woman who has diagnosed with Turner syndrome with a karyotype of 46,X,i(X)(q10) visited for hypertension and mild headache. Transthoracic echography (TTE) showed no definite persistent ductus arteriosus shunt flow and cardiac valve abnormalities. Considering other important secondary causes like pheochromocytoma, hormonal studies were performed and the results showed increased serum norepinephrine, serum normetanephrine, and 24 h urine norepinephrine. We performed an abdominal computed tomography (CT) to confirm the location of pheochromocytoma. Abdominal CT showed a 1.9 cm right adrenal mass. I-131 meta-iodobenzylguanidine (MIBG) scintigraphy showed a right adrenal uptake. Laparoscopic adrenalectomy was performed and confirmed a pheochromocytoma. After surgery, blood pressure was within normal ranges and postoperative course was uneventful, and no recurrence developed via biochemical tests and abdominal CT until 24 months. Our case and previous literatures suggest that hypertension caused by pheochromocytoma which is a rare but important and potentially lethal cause of hypertension in Turner syndrome. This case underlines the importance of early detection of pheochromocytoma in Turner syndrome. Clinicians should keep in mind that pheochromocytoma can be a cause of hypertension in patients with Turner syndrome.

We report here a new case of pyoderma gangrenosum (PG) associated with a breast cancer in a 39-year-old woman. We only found in literature three other reports of this rare entity which seems usually to be associated with monoclonal gammopathy, gastro-intestinal diseases such as Crohn's disease, chronic ulcerative colitis, leukemias or rheumatologic diseases. A commun hapten between of tumor and skin may explain the origin of this inflammatory lesion. In our case, PG could be a paraneoplastic syndrome.

Down syndrome, RASopathies, and other rare syndromes.

In this article we discuss the occurrence of myeloid neoplasms in patients with a range of syndromes that are due to germline defects of the RAS signaling pathway and in patients with trisomy 21. Both RAS mutations and trisomy 21 are common somatic events contributing to leukemogenis. Thus, the increased leukemia risk observed in children affected by these conditions is biologically highly plausible. Children with myeloid neoplasms in the context of these syndromes require different treatments than children with sporadic myeloid neoplasms and provide an opportunity to study the role of trisomy 21 and RAS signaling during leukemogenesis and development.

A 52-year-old man with vertigo and imbalance for two weeks showed spontaneous downbeat (DBN), horizontal gaze-evoked, and positional apogeotropic nystagmus along with severe limb and truncal ataxia. Gadolinium-enhanced brain MRI was normal, but whole body and brain 2-deoxy-2-[F18]fluoro-d-glucose-positron emission tomography revealed hypermetabolism in the right lower lobe of the lung and the cerebellum, especially in the nodulus. The lesion in the lung was confirmed as mixed cell carcinoma. Paraneoplastic DBN may be associated with cerebellar hypermetabolism, especially in the nodulus. Copyright © 2014 Elsevier B.V.

Joshi, Prathamesh; Lele, Vikram

2013-04-01

Opsoclonus-myoclonus ataxia (OMA) syndrome is the most common paraneoplastic neurological syndrome of childhood, associated with occult neuroblastoma in 20%-50% of all cases. OMA is the initial presentation of neuroblastoma in 1%-3% of children. Conventional radiological imaging approaches include chest radiography and abdominal computed tomography (CT). Nuclear medicine techniques, in form of (123)I/(131)I-metaiodobenzylguanidine (MIBG) scintigraphy have been incorporated in various diagnostic algorithms for evaluation of OMA. We describe use of somatostatin receptor PET/CT with (68)Gallium- DOTA-DPhe(1), Tyr(3)-octreotate (DOTATATE) in diagnosis of neuroblastoma in two cases of OMA.

Autoimmune paraneoplastic syndromes are commonly encountered in patients with myelodysplastic syndromes (MDS). A review of case reports and small series suggest as many as 10% of MDS patients may experience various autoimmune syndromes. Clinical manifestations of such phenomena may include an acute systemic vasculitic syndrome, skin vasculitis, fever, arthritis, pulmonary infiltrates, peripheral polyneuropathy, inflammatory bowel disease, glomerulonephritis, and even classical connective tissue disorders, such as relapsing polychondritis. On the other hand, asymptomatic immunologic abnormalities have also been reported in these patients. These autoimmune manifestations frequently respond to immunosuppressive agents including steroids and occasional hematologic responses to steroid therapy have also been reported. We report five patients with history of MDS who manifested different spectrums of autoimmune phenomena including: pyoderma gangrenosum (PG), vasculitis, Coombs negative hemolytic anemia, idiopathic thrombocytopenia, and chronic inflammatory demyelinating polyneuropathy (CIDP). We also review the incidence, nature, course and response to therapy of these manifestations and discuss potential pathogenic mechanisms.

Paraneoplastic pemphigus (PP) is an autoimmune disease, which is frequently associated with non-Hodgkin's lymphoma. Autoantibodies against components of the cytoplasmic plaque of epithelial desmosomes are usually present in the sera and are believed to play a major pathogenic part in acantholysis and suprabasal epidermal blistering. However, another typical histological feature of PP, interface dermatitis with keratinocyte dyskeratosis, is shared with skin diseases that involve epithelial damage mediated by T cells. Here, we present the detailed characterization of the cutaneous T-cell response in a patient with PP and demonstrate a selective epidermal accumulation of activated CD8+ T cells together with an increased local production of interferon-gamma and tumour necrosis factor-alpha, and a strong expression of HLA-DR and ICAM-1 on keratinocytes. Apoptosis was identified as a key mechanism of keratinocyte death, and appeared independent of the FAS/FAS ligand (FAS-L) pathway, as epidermal expression of FAS was not increased compared with normal skin, and FAS-L was undetectable on the protein and mRNA level. Triple therapy with high-dose corticosteroids, cyclophosphamide and intravenous immunoglobulins reduced levels of pemphigus-like autoantibodies and reversed the cutaneous inflammatory reaction leading to long-standing clinical remission. Our findings support the concept of a major contribution of cytotoxic T lymphocytes to the immunopathology of paraneoplastic pemphigus.

2015-10-01

Ectrodactyly-ectodermal dysplasia and clefting syndrome or "Lobster claw" deformity is a rare congenital anomaly that affects tissues of ectodermal and mesodermal origin. Nasolacrimal duct (NLD) obstruction with or without atresia of lacrimal passage is a common finding of such a syndrome. The authors report here even a rarer presentation of the syndrome which manifested as bilateral NLD obstruction and lacrimal fistula along with cleft lip and palate, syndactyly affecting all four limbs, mild mental retardation, otitis media, and sinusitis. Lacrimal duct obstruction and fistula were managed successfully with endoscopic dacryocystorhinostomy (DCR) which is a good alternative to lacrimal probing or open DCR in such a case.

Cancer and autoimmunity: autoimmune and rheumatic features in patients with malignancies

PubMed Central

Abu-Shakra, M; Buskila, D; Ehrenfeld, M; Conrad, K; Shoenfeld, Y

2001-01-01

OBJECTIVES—To review the autoimmune and rheumatic manifestations of patients with malignancy.
METHODS—A Medline search of all published papers using keywords related to malignancies, autoimmunity, rheumatic diseases, and paraneoplastic syndromes.
RESULTS—Patients with malignant diseases may develop autoimmune phenomena and rheumatic diseases as a result of (a) generation of autoantibodies against various autoantigens, including oncoproteins (P185, 1-myc, c-myc, c-myb), tumour suppression genes (P53), proliferation associated antigens (cyclin A, B1, D1, E; CENP-F; CDK, U3-RNP), onconeural antigens (Hu, Yo, Ri, Tr), cancer/testis antigens (MAGE, GAGE, BAGE, SSX, ESO, SCP, CT7), and rheumatic disease associated antigens (RNP, Sm). The clinical significance of the various autoantibodies is not clear. Anti-oncoprotein and anti-tumour suppression gene antigens are detected before the diagnosis of the cancer or in the early stages of the malignant disease, suggesting a potential diagnostic or prognostic role. Anti-onconeural antibodies are pathogenic and are associated with specific clinical neurological syndromes (anti-Hu syndrome and others). (b) Paraneoplastic syndromes, a wide range of clinical syndromes, including classic autoimmune rheumatic diseases that develop among patients with cancer. (c) Rheumatism after chemotherapy, a clinical entity characterised by the development of musculoskeletal symptoms after combination chemotherapy for malignancy.
CONCLUSION—Autoimmune and rheumatic features are not rare among patients with malignancies. They are the result of various diverse mechanisms and occasionally they may be associated with serious clinical entities.

Kounis syndrome is an acute coronary syndrome in the context of a hypersensitivity reaction. The main pathophysiological mechanism appears to be coronary vasospasm. We report the case of a patient with a history of allergy to quinolones, who was given ciprofloxacin before an elective surgical procedure and during drug administration developed symptoms and electrocardiographic changes suggestive of ST-segment elevation acute coronary syndrome. The drug was suspended and coronary angiography excluded epicardial coronary disease. Two hours after withdrawal of the drug the symptoms and ST elevation had resolved completely.

Kearns-Sayre syndrome (KSS) is a rare mitochondrial DNA deletion syndrome defined as the presence of ophthalmoplegia, pigmentary retinopathy, onset less than age 20 years, and one of the following: cardiac conduction defects, cerebellar syndrome, or cerebrospinal fluid protein above 100 mg/dl. KSS may affect many organ systems causing endocrinopathies, encephalomyopathy, sensorineural hearing loss, and renal tubulopathy. Clinical presentation at diagnosis is quite heterogeneous and, usually, few organs are affected with progression to generalized disease early in adulthood. We present the case of a boy with KSS presenting at the age of 5 years with myopathy, Addison's disease, primary hypoparathyroidism, and Fanconi syndrome. The proper replacement treatment along with the administration of mitochondrial metabolism-improving agents had a brief ameliorating effect, but gradual severe multisystemic deterioration was inevitable over the next 5 years. This report highlights the fact that in case of simultaneous presentation of polyendocrinopathies and renal disease early in childhood, KSS should be considered.

The tubulo-interstitial nephritis and uveitis (TINU) syndrome, first described in 1975, is a rare disease most probably of autoimmune origin that is characterized by unilateral or bilateral uveitis and tubulointerstitial nephritis. Most patients are adolescents and it is sometimes associated with other autoimmune diseases, such as spondyloarthritis, rheumatoid arthritis and hyperthyroidosis. This article reports the case of a 43-year-old female patient who presented with refractory recurrent bilateral uveitis despite therapy with high doses of corticosteroids in combination with cyclosporin. When the patient was referred to this hospital for rheumatological examination after almost 1 year of therapy, mild renal insufficiency and proteinuria were found. The kidney biopsy revealed interstitial nephritis, partly crescent-shaped and partly chronic. A diagnosis of TINU syndrome was made and treatment with adalimumab in combination with methotrexate was started. The favorable clinical outcome indicated that tumor necrosis factor (TNF) alpha may play an important role in the pathogenesis of TINU syndrome.

Noonan syndrome is an autosomal dominant, multisystemic disorder caused by dysregulation of the RAS/mitogen activated protein kinase (MAPK) pathway. Heterozygous, pathogenic variants in 11 known genes account for approximately 80% of cases. The identification of novel genes associated with Noonan syndrome has become increasingly challenging, since they might be responsible for very small fractions of the cases. A cohort of 50 Brazilian probands negative for pathogenic variants in the known genes associated with Noonan syndrome was tested through whole-exome sequencing along with the relatives in the familial cases. Families from the USA and Poland with mutations in the newly identified genes were included subsequently. We identified rare, segregating or de novo missense variants in SOS2 and LZTR1 in 4% and 8%, respectively, of the 50 Brazilian probands. SOS2 and LZTR1 variants were also found to segregate in one American and one Polish family. Notably, SOS2 variants were identified in patients with marked ectodermal involvement, similar to patients with SOS1 mutations. We identified two novel genes, SOS2 and LZTR1, associated with Noonan syndrome, thereby expanding the molecular spectrum of RASopathies. Mutations in these genes are responsible for approximately 3% of all patients with Noonan syndrome. While SOS2 is a natural candidate, because of its homology with SOS1, the functional role of LZTR1 in the RAS/MAPK pathway is not known, and it could not have been identified without the large pedigrees. Additional functional studies are needed to elucidate the role of LZTR1 in RAS/MAPK signalling and in the pathogenesis of Noonan syndrome. Published by the BMJ Publishing Group Limited.

Paraneoplastic cerebellar ataxia (PCA) is most frequently observed in gynaecological cancers, small cell lung cancer, breast cancer, Hodgkin's lymphoma, cancer testis or malignant thymoma. In the literature, there is no data related to the effects of PCA during pregnancy or reports on the effects of anaesthesia in patients with PCA. We present management of a pregnant woman with PCA who was suddenly unable to walk with PCA and for whom effective spinal anaesthesia was performed for an elective caesarean section with no complications.

Abdominal wall Actinomycosis is a rare disease associated with the use of intrauterine device and as a complication of abdominal surgery. Diagnosis is difficult because it is unusual and behaves like a malignant neoplasm. A case report is presented of a patient who had used an intrauterine device for four years and developed a stony tumour in the abdominal wall associated with a set of symptoms that, clinically and radiologically, was simulating a peritoneal carcinomatosis associated with paraneoplastic syndrome, even in the course of an exploratory laparotomy. The patient attended our hospital with a two-month history of abdominal pain and symptoms that mimic a paraneoplastic syndrome. The diagnosis of abdominal actinomycosis was suspected by the finding of the microorganism in cervical cytology together with other cultures and Actinomyces negative in pathological studies, confirming the suspicion of a complete cure with empirical treatment with penicillin. Actinomycosis should be considered in patients with pelvic mass or abdominal wall mass that mimics a malignancy. Antibiotic therapy is the first treatment choice and makes a more invasive surgical management unnecessary. Copyright © 2015 Academia Mexicana de Cirugía A.C. Published by Masson Doyma México S.A.

Williams-Beuren syndrome (WBS) is caused by a hemizygous contiguous gene microdeletion of 1.55-1.84 Mb at 7q11.23 region. Approximately, 28 genes have been shown to contribute to classical phenotype of SWB with presence of dysmorphic facial features, supravalvular aortic stenosis (SVAS), intellectual disability, and overfriendliness. With the use of Microarray-based comparative genomic hybridization and other molecular cytogenetic techniques, is possible define with more accuracy partial or atypical deletion and refine the genotype-phenotype correlation. Here, we report on a rare genomic structural rearrangement in a boy with atypical deletion in 7q11.23 and XYY syndrome with characteristic clinical signs, but not sufficient for the diagnosis of WBS. Cytogenetic analysis of G-banding showed a karyotype 47,XYY. Analysis of DNA with the technique of MLPA (Multiplex Ligation-dependent Probe Amplification) using kits a combination of kits (P064, P036, P070, and P029) identified an atypical deletion on 7q11.23. In addition, high resolution SNP Oligonucleotide Microarray Analysis (SNP-array) confirmed the alterations found by MLPA and revealed others pathogenic CNVs, in the chromosomes 7 and X. The present report demonstrates an association not yet described in literature, between Williams-Beuren syndrome and 47,XYY. The identification of atypical deletion in 7q11.23 concomitant to additional pathogenic CNVs in others genomic regions allows a better comprehension of clinical consequences of atypical genomic rearrangements. © 2015 Wiley Periodicals, Inc.

Background Rare diseases (RD) are those that present a lower prevalence than 5 cases per 10.000 population. The main objective of this review was to study the effect on oral health in rare diseases, while the secondary objective of the study is theme upgrade. Material and Methods Comparative observational case-control studies were analysed and a systematic review was conducted in PubMed. Each rare disease listed on the statistical data record of the Health Portal of the Ministry of Equality, Health and Social Policies Board of Andalusia was associated with “oral health”. The variables studied included dental, oral mucosa and occlusion alterations, oral pathologies (caries, periodontal disease) and other alterations (mouth breathing, parafunctional habits, etc). A bias analysis of the variable caries was conducted. Results Six RD were selected through our inclusion and exclusion criteria (hypogammaglobulinemia, Rett syndrome, Marfan syndrome, Prader-Willi syndrome, cystic fibrosis and Cri du chat syndrome) in a total of 8 publications, of which four trials were classified as high risk of bias and one of them as medium risk. There were not trials with low risk of bias. Conclusions The main statistically significant differences found by Syndrome compared to a control group were in Hypogammaglobulinemia with a greater tendency to enamel hypoplasia and dry mouth. The Rett syndrome had, as well, a greater tendency to an anterior open bite, ogival palate, bruxism, mouth breathing and tongue thrusting. Prader-Willi syndrome had a tendency of dental erosion, and Cri du chat syndrome showed a higher association to Tannerella forsythia. Key words:Rare diseases, oral health. PMID:27475682

Hypoplastic right heart syndrome (HRHS) is a rare congenital defect characterized by underdevelopment of the right heart structures commonly accompanied by an atrial septal defect. Familial HRHS reports suggest genetic factor involvement. We examined the role of copy number variants (CNVs) in HRHS. We genotyped 32 HRHS cases identified from all New York State live births (1998-2005) using Illumina HumanOmni2.5 microarrays. CNVs were called with PennCNV and prioritized if they were ≥20 Kb, contained ≥10 SNPs and had minimal overlap with CNVs from in-house controls, the Database of Genomic Variants, HapMap3, and Childrens Hospital of Philadelphia database. We identified 28 CNVs in 17 cases; several encompassed genes important for right heart development. One case had a 2p16-2p23 duplication spanning LBH, a limb and heart development transcription factor. Lbh mis-expression results in right ventricular hypoplasia and pulmonary valve defects. This duplication also encompassed SOS1, a factor associated with pulmonary valve stenosis in Noonan syndrome. Sos1 -/- mice display thin and poorly trabeculated ventricles. In another case, we identified a 1.5 Mb deletion associated with Williams-Beuren syndrome, a disorder that includes valvular malformations. A third case had a 24 Kb deletion upstream of the TGFβ ligand ITGB8. Embryos genetically null for Itgb8, and its intracellular interactant Band 4.1B, display lethal cardiac phenotypes. To our knowledge, this is the first study of CNVs in HRHS. We identified several rare CNVs that overlap genes related to right ventricular wall and valve development, suggesting that genetics plays a role in HRHS and providing clues for further investigation.

A rare presentation of atypical demyelination: tumefactive multiple sclerosis causing Gerstmann’s syndrome

PubMed Central

2014-01-01

Background Tumefactive demyelinating lesions are a rare manifestation of multiple sclerosis (MS). Differential diagnosis of such space occupying lesions may not be straightforward and sometimes necessitate brain biopsy. Impaired cognition is the second most common clinical manifestation of tumefactive MS; however complex cognitive syndromes are unusual. Case presentation We report the case of a 30 year old woman who presented with Gerstmann’s syndrome. MRI revealed a large heterogeneous contrast enhancing lesion in the left cerebral hemisphere. Intravenous corticosteroids did not stop disease progression. A tumour or cerebral lymphoma was suspected, however brain biopsy confirmed inflammatory demyelination. Following diagnosis of tumefactive MS treatment with natalizumab effectively suppressed disease activity. Conclusions The case highlights the need for clinicians, radiologists and surgeons to appreciate the heterogeneous presentation of tumefactive MS. Early brain biopsy facilitates rapid diagnosis and management. Treatment with natalizumab may be useful in cases of tumefactive demyelination where additional evidence supports a diagnosis of relapsing MS. PMID:24694183

Gorlin-Goltz syndrome (GS), also known as nevoid basal cell carcinoma syndrome, is an infrequent multisystem disease inherited in a dominant autosomal way, which shows a high level of penetrance and variable expressiveness. It is characterised by keratocystic odontogenic tumours (KCOT) in the jaw, multiple basal cell nevi carcinomas and skeletal abnormalities. This syndrome may be diagnosed early by a dentist by routine radiographical examinations in the first decade of life, since the KCOTs are usually one of the first manifestations of the syndrome. This article describes an 11-year-old boy with GS.

Neurological decompression sickness (DCS) is a rare condition that commonly leads to spinal cord injury. We report the case of a 30-year-old man who developed left-sided weakness and numbness after diving to a maximum depth of 15 m with a total dive time of 205min (10 repetitive dives). To the best of our knowledge, only six cases diagnosed as Brown-Séquard syndrome caused by DCS have been reported in the literature. Divers should be aware of the risk factors of DCS before diving and clinicians should make the diagnosis of spinal cord DCS based primarily on clinical symptoms, not on magnetic resonance imaging findings. © The Author 2015.

Tumor-induced osteomalacia (TIO) is a rare cause of hypophosphatemia involving overproduction of fibroblast growth factor 23. TIO has been described largely in adults with small mesenchymal tumors. We report a case of TIO in a child who presented with knee pain and radiographic findings concerning for rickets, and was found to have maxillomandibular giant cell lesions. The patient was treated with oral phosphorus and calcitriol, surgical debulking, and intralesional corticosteroids, which resulted in tumor regression and normalization of serum fibroblast growth factor 23 and phosphorus. This case illustrates the occurrence of this rare paraneoplastic syndrome in children and adds to our knowledge about clinical manifestations and pathologic findings associated with pediatric TIO.

Gorlin-Goltz syndrome: a rare case report

PubMed Central

Mohan, Ravi Prakash Sasankoti; Verma, Sankalp; Agarwal, Neha; Singh, Udita

2013-01-01

Gorlin-Goltz syndrome (GS), also known as nevoid basal cell carcinoma syndrome, is an infrequent multisystem disease inherited in a dominant autosomal way, which shows a high level of penetrance and variable expressiveness. It is characterised by keratocystic odontogenic tumours (KCOT) in the jaw, multiple basal cell nevi carcinomas and skeletal abnormalities. This syndrome may be diagnosed early by a dentist by routine radiographical examinations in the first decade of life, since the KCOTs are usually one of the first manifestations of the syndrome. This article describes an 11-year-old boy with GS. PMID:23814215

Hypophosphataemia due to FGF-23 producing B cell non-Hodgkin's lymphoma

Elderman, Jan H; Wabbijn, Marike; de Jongh, Felix

2016-01-01

Oncogenic osteomalacia (or tumour-induced osteomalacia) is a rare paraneoplastic syndrome caused by overproduction of fibroblastic growth factor 23 (FGF-23) by tumours. Excessive production of FGF-23 can lead to severe, symptomatic hypophosphataemia. The majority of cases have been associated with benign tumours of bone or soft tissue, such as haemangiopericytomas or other neoplasms of mesenchymal origin. We present a case of a 68-year-old woman with an FGF-23 producing B cell non-Hodgkin's lymphoma. Treatment with immunochemotherapy resulted in normalisation of serum FGF-23 and phosphate levels.

Tumour-induced osteomalacia (TIO) is a rare paraneoplastic syndrome characterised by severe hypophosphataemia and osteomalacia, with renal phosphate wasting that occurs in association with tumour. The epidemiology likewise aetiology is not known. The clinical presentation of TIO includes bone fractures, bone and muscular pains, and sometimes height and weight loss. TIO may be associated with mesenchymal tumours which may be benign or malignant in rare cases. Mesenchymal tumour itself may be related to fibroblast growth factor 23 (FGF23), which is responsible for hypophosphataemia and phosphaturia occurring in this paraneoplastic syndrome. Hypophosphataemia, phosphaturia and elevated alkaline phosphatase are the main laboratory readings that may lead to more precise investigations and better diagnosis. Finding the tumour can be a major diagnostic challenge and may involve total body magnetic resonance imaging, computed tomography and scintigraphy using radiolabelled somatostatin analogue. The treatment of choice for TIO is resection of a tumour with a wide margin to insure complete tumour removal, as recurrences of these tumours have been reported. We provide here an overview on the current available TIO case reports and review the best practices that may lead to earlier recognition of TIO and the subsequent treatment thereof, even though biochemical background and the long-term prognosis of the disease are not well understood. This review also includes a 4-year-long history of a patient that featured muscular pains, weakness and multiple stress fractures localised in the hips and vertebra with subsequent recovery after tumour resection. Because the occurrence of such a condition is rare, it may take years to correctly diagnose the disease, as is reported in this case report.

Recently, germline mutations of NRAS have been shown to be associated with Noonan syndrome (NS), a relatively common developmental disorder characterized by short stature, congenital heart disease, and distinctive facial features. We report on the mutational analysis of NRAS in a cohort of 125 French patients with NS and no known mutation for PTPN11, KRAS, SOS1, MEK1, MEK2, RAF1, BRAF, and SHOC2. The c.179G>A (p.G60E) mutation was identified in two patients with typical NS, confirming that NRAS germline mutations are a rare cause of this syndrome. We also screened our cohort of 95 patients with juvenile myelomonocytic leukemia (JMML). Among 17 patients with NRAS-mutated JMML, none had clinical features suggestive of NS. None of the 11 JMML patients for which germline DNA was available had a constitutional NRAS mutation. Copyright © 2012 Wiley Periodicals, Inc.

Background Social media is increasingly being used as a means of recruiting participants, particularly for investigators whose areas of interest involve rare conditions or hard-to-reach populations. However, much of the literature to date has focused on paid advertisement recruitment. Objective We used Lynch syndrome (LS), a rare hereditary cancer syndrome, as a model to demonstrate the successful partnership between researchers and a Web-based patient education and advocacy organization to facilitate participant recruitment. Methods Recruitment was undertaken in partnership with Lynch Syndrome International (LSI), an advocacy organization with a strong social media presence. After LSI published our study information, participants followed up via email or phone call. Following prescreening and consent, interested and eligible participants were then sent a secure survey link. Results Within 36 hours of a single Facebook post by the site administrators for LSI, over 150 individuals responded via phone or email. Sixty-five individuals were sent the survey link and 57 individuals completed the survey (88% response rate). Of note, these 57 individuals were geographically diverse within the Unites States, representing LS patients from 26 different states. Conclusions This approach has several advantages, including recruitment through a trusted source outside of a clinical setting, higher response rates, and cost-effectiveness with a small research team in a relatively short amount of time. Overall, social media recruitment with a trusted online partner can be highly effective in hard-to-reach clinical populations, such as patients with LS. However, this approach requires additional effort for eligibility screening. PMID:28115298

Evidence for distinct human cancer stem cells (CSCs) remains contentious and the degree to which different cancer cells contribute to propagating malignancies in patients remains unexplored. In low- to intermediate-risk myelodysplastic syndromes (MDS), we establish the existence of rare multipotent MDS stem cells (MDS-SCs), and their hierarchical relationship to lineage-restricted MDS progenitors. All identified somatically acquired genetic lesions were backtracked to distinct MDS-SCs, establishing their distinct MDS-propagating function in vivo. In isolated del(5q)-MDS, acquisition of del(5q) preceded diverse recurrent driver mutations. Sequential analysis in del(5q)-MDS revealed genetic evolution in MDS-SCs and MDS-progenitors prior to leukemic transformation. These findings provide definitive evidence for rare human MDS-SCs in vivo, with extensive implications for the targeting of the cells required and sufficient for MDS-propagation.

Gastrointestinal complications are common in patients with Ehlers-Danlos Syndrome, affecting up to 50% of individuals depending on the subtype. The spectrum of gastrointestinal manifestations is broad and ranges from life threatening spontaneous perforation of the visceral organs to a more benign functional symptoms. Here we describe the clinical and radiographic manifestations of visceroptosis of the bowel, a rare complication of Ehlers-Danlos Syndrome that is characterized by prolapse of abdominal organs below their natural position. We further review the literature on gastrointestinal complications in the different forms of Ehlers-Danlos Syndrome. PMID:22781752

Anti-Ma2 antibody related paraneoplastic limbic/brain stem encephalitis associated with breast cancer expressing Ma1, Ma2, and Ma3 mRNAs.

2003-09-01

A 69 year old woman presented with cognitive impairment and supranuclear gaze palsy caused by paraneoplastic limbic/brain stem encephalitis associated with atypical medullary breast carcinoma. The cerebrospinal fluid from the patient harboured an anti-neuronal cell antibody against Ma2 antigen, but not against Ma1 or Ma3 antigen. Despite the antibody being restricted to the Ma2 antigen, the patient's cancer tissue expressed Ma1, Ma2, and Ma3 mRNAs. These results, and the expression of Ma2 mRNA in an atypical medullar breast carcinoma in another patient without paraneoplastic encephalitis, indicate that the induction of anti-Ma2 antibody depends on host immunoreponsiveness and not on the presence of the antigen itself in the cancer.

Patient-support organizations can facilitate a significant change in the way rare disorders are approached. Besides connecting families with each other and directing patients to experienced medical specialists, these groups, by collaborating with government initiatives like COST, can effect the direction and funding of rare disease research. By concentrating the rare disease patient population and funneling them to specific centers of excellence, these organizations help build specialists' experience and their study populations. It requires a basic spirit of collaboration, driven parent leaders, a well-organized support platform, sources of funding, supportive clinical and research professionals and finally an effective method of collecting and disseminating information. Silver-Russell Syndrome is an excellent example of a rare disorder that has become better recognized, understood and treated because patient-support organizations, using the internet as a critical tool, have worked together with clinical care/research specialists and public funding agencies to build collaboration.

Chopra, Rupali; Chander, Ashish; Jacob, Jubbin J.

2012-01-01

The human eye, as an organ, can offer critical clues to the diagnosis of various systemic illnesses. Ocular changes are common in various endocrine disorders such as diabetes mellitus and Graves’ disease. However there exist a large number of lesser known endocrine disorders where ocular involvement is significant. Awareness of these associations is the first step in the diagnosis and management of these complex patients. The rare syndromes involving the pituitary hypothalamic axis with significant ocular involvement include Septo-optic dysplasia, Kallman's syndrome, and Empty Sella syndrome all affecting the optic nerve at the optic chiasa. The syndromes involving the thyroid and parathyroid glands that have ocular manifestations and are rare include Mc Cune Albright syndrome wherein optic nerve decompression may occur due to fibrous dysplasia, primary hyperparathyroidism that may present as red eye due to scleritis and Ascher syndrome wherein ptosis occurs. Allgrove's syndrome, Cushing's disease, and Addison's disease are the rare endocrine syndromes discussed involving the adrenals and eye. Ocular involvement is also seen in gonadal syndromes such as Bardet Biedl, Turner's, Rothmund's, and Klinefelter's syndrome. This review also highlights the ocular manifestation of miscellaneous syndromes such as Werner's, Cockayne's, Wolfram's, Kearns Sayre's, and Autoimmune polyendocrine syndrome. The knowledge of these relatively uncommon endocrine disorders and their ocular manifestations will help an endocrinologist reach a diagnosis and will alert an ophthalmologist to seek specialty consultation of an endocrinologist when encountered with such cases.

Excess glucocorticoid levels cause Cushing's syndrome (CS) and may be due to pituitary, adrenal or ectopic tumours. Adrenocorticotropic hormone (ACTH) levels are useful in identifying adrenal tumours. In rare cases, ACTH-producing phaeochromocytomas are the cause of CS. We present two cases of ACTH-secreting phaeochromocytoma as the underlying cause of CS. In both cases, female patients presented with the classical clinical signs of CS and an adrenal mass. High ACTH levels raised the suspicion of an ACTH-secreting phaeochromocytoma. The diagnosis was confirmed by urinary catecholamine levels and positive fluorine-18-L-dihydroxyphenylalanine (18F-DOPA) positron emission tomography (PET) CT (Case 1) and fluorodeoxyglucose PET-CT (Case 2). Both patients were treated with an α-blocker prior to surgical intervention. The two cases underline the importance of thorough diagnostic workup in patients with CS. An ACTH-secreting phaeochromocytoma should be checked for in patients with an adrenal mass and elevated ACTH levels. 2014 BMJ Publishing Group Ltd.

Objectives: To determine the characteristics of adult-onset autoimmune chorea, and compare paraneoplastic and idiopathic subgroups. Methods: Thirty-six adults with autoimmune chorea were identified at Mayo Clinic (Rochester, MN) from 1997 to 2012. Medical record and laboratory data were recorded. Nonparaneoplastic (n = 22) and paraneoplastic cases (n = 14) were compared. Results: Women accounted for 21 patients (58%). Median age at symptom onset was 67 years (range 18–87 years). We estimated the incidence for Olmsted County was 1.5 per million person-years. Symptom onset was subacute in all. Chorea was focal (20 patients) or generalized (16 patients). Although chorea predominated, other neurologic disorders frequently coexisted (29 patients); abnormal eye movements were uncommon (4 patients). No patient had NMDA receptor antibody or any immunoglobulin (Ig)G yielding a detectable immunofluorescence binding pattern restricted to basal ganglia. Two had synaptic IgG antibodies novel to the context of chorea (GAD65, 1; CASPR2, 1). In the paraneoplastic group, 14 patients had evidence of cancer. Of 13 with a histopathologically confirmed neoplasm, small-cell carcinoma and adenocarcinoma were most common; 6 patients had a cancer-predictive paraneoplastic autoantibody, with CRMP-5–IgG and ANNA-1 being most common. In the idiopathic group, 19 of the 22 patients had a coexisting autoimmune disorder (most frequently systemic lupus erythematosus and antiphospholipid syndrome); autoantibodies were detected in 21 patients, most frequently lupus and phospholipid specificities (19 patients). The paraneoplastic group was older (p = 0.001), more frequently male (p = 0.006), had more frequent weight loss (p = 0.02), and frequently had peripheral neuropathy (p = 0.008). Conclusions: Autoimmune chorea is a rare disorder with rapid onset. Male sex, older age, severe chorea, coexisting peripheral neuropathy, and weight loss increase the likelihood of cancer.

Sotos syndrome is a childhood overgrowth syndrome characterized by a distinctive facial appearance, height and head circumference >97th percentile, advanced bone age, and developmental delay. Weaver syndrome is characterized by the same criteria but has its own distinctive facial gestalt. Recently, a 2.2-Mb chromosome 5q35 microdeletion, encompassing NSD1, was reported as the major cause of Sotos syndrome, with intragenic NSD1 mutations identified in a minority of cases. We evaluated 75 patients with childhood overgrowth, for intragenic mutations and large deletions of NSD1. The series was phenotypically scored into four groups, prior to the molecular analyses: the phenotype in group 1 (n=37) was typical of Sotos syndrome; the phenotype in group 2 (n=13) was Sotos-like but with some atypical features; patients in group 3 (n=7) had Weaver syndrome, and patients in group 4 (n=18) had an overgrowth condition that was neither Sotos nor Weaver syndrome. We detected three deletions and 32 mutations (13 frameshift, 8 nonsense, 2 splice-site, and 9 missense) that are likely to impair NSD1 functions. The truncating mutations were spread throughout NSD1, but there was evidence of clustering of missense mutations in highly conserved functional domains between exons 13 and 23. There was a strong correlation between presence of an NSD1 alteration and clinical phenotype, in that 28 of 37 (76%) patients in group 1 had NSD1 mutations or deletions, whereas none of the patients in group 4 had abnormalities of NSD1. Three patients with Weaver syndrome had NSD1 mutations, all between amino acids 2142 and 2184. We conclude that intragenic mutations of NSD1 are the major cause of Sotos syndrome and account for some Weaver syndrome cases but rarely occur in other childhood overgrowth phenotypes.

Ankyloglossia or tongue-tie is a congenital anomaly affecting the tongue, which is characterized by thick, short lingual frenulum. This condition causes many difficulties such as limited tongue protrusion, breastfeeding difficulties, speech impairment and lack of self-confidence. It is very rarely associated with any other congenital craniofacial disorders such as cleft lip, X-linked cleft palate, Van der Woude syndrome, Smith-Lemli-Opitz syndrome, Orofacial digital syndrome, Beckwith Weidman syndrome or Simpson-Golabi-Behmel syndrome. This article presents a rare case of ankyloglossia associated with cleft lip treated with diode laser in a 12-year-old Indian boy who had undergone surgical correction of associated cleft lip soon after birth. Correction of ankyloglossia at a young age would lead to enhanced phonetics, improved oral hygiene, and overall personality development. PMID:26941523

Middle aortic syndrome (MAS) follows a course with distal thoracic and abdominal aorta stenosis. It is a rare disease that is usually diagnosed after the first decade of life. Clinical reflection of MAS is often in the form of hypertension and claudication in the lower extremities. Its etiology is unclear, but is known to be associated with congenital or acquired diseases. This pathology, which is accompanied by malignant hypertension, often does not respond to medical treatment. In patients with MAS, surgical treatment is first line recommendation to prevent complications such as hypertension, heart failure, intracranial bleeding, or aortic rupture. In order to draw attention to this disease, presently described is case of high blood pressure detected during routine examination of a child who had no complaint, and discovery of long-segment stenosis in the abdominal aorta identified with echocardiography and conventional angiography.

Fibroblast Growth Factor 23–Induced Hypophosphatemia in Acute Leukemia

2018-01-01

Abstract Fibroblast growth factor 23 (FGF23)–induced hypophosphatemia is a rare paraneoplastic syndrome of phosphate wasting that, if unrecognized, may cause tumor-induced osteomalacia. It is classically associated with benign mesenchymal tumors but occasionally has been found in patients with other malignancies. Hypophosphatemia has been associated with acute leukemia but has not previously been reported to be due to inappropriate FGF23 secretion. Here, we describe FGF23-induced severe hypophosphatemia and renal phosphate wasting associated with a mixed-phenotype Philadelphia chromosome-like acute leukemia in a previously healthy 22-year-old man. He was found to have low serum 1,25-dihydroxyvitamin D and extremely high FGF23 levels, as well as inappropriate urinary phosphorus excretion. The hypophosphatemia improved with calcitriol and oral phosphate treatment but normalized only during chemotherapy-induced ablation of the blasts. FGF23 levels declined with a reduction in peripheral blast counts. Using real-time reverse transcription polymerase chain reaction, we found that the leukemia cells were the source of FGF23. To our knowledge, this is the first description of FGF23-induced hypophosphatemia associated with acute leukemia. We recommend that the FGF23 paraneoplastic syndrome be considered as a possible etiology of hypophosphatemia in patients with acute leukemia. PMID:29696242

Tumor-induced osteomalacia (TIO) is a rare paraneoplastic syndrome that results in renal phosphate wasting with hypophosphatemia. In most cases, the underlying cause of TIO is a small mesenchymal neoplasm that is often difficult to detect, resulting in delayed diagnosis. One such neoplasm is the phosphaturic mesenchymal tumor, mixed connective tissue variant (PMTMCT), an unusual entity with unique morphologic and biochemical features. Most of these tumors are found at appendicular sites with only rare cases reported in the jaws. We describe a PMTMCT involving the mandible in a patient with a protracted history of osteomalacia. A review of the current literature is provided with emphasis on the clinical and histologic features, etiopathogenesis, and management of PMTMCT in the setting of TIO.

Paraneoplastic neurologic diseases (PND) involving immune responses directed toward intracellular antigens are poorly understood. Here, we examine immunity to the PND antigen Nova2, which is expressed exclusively in central nervous system (CNS) neurons. We hypothesized that ectopic expression of neuronal antigen in the periphery could incite PND. In our C57BL/6 mouse model, CNS antigen expression limits antigen-specific CD4+ and CD8+ T-cell expansion. Chimera experiments demonstrate that this tolerance is mediated by antigen expression in nonhematopoietic cells. CNS antigen expression does not limit tumor rejection by adoptively transferred transgenic T cells but does limit the generation of a memory population that can be expanded upon secondary challenge in vivo. Despite mediating cancer rejection, adoptively transferred transgenic T cells do not lead to paraneoplastic neuronal targeting. Preliminary experiments suggest an additional requirement for humoral activation to induce CNS autoimmunity. This work provides evidence that the requirements for cancer immunity and neuronal autoimmunity are uncoupled. Since humoral immunity was not required for tumor rejection, B-cell targeting therapy, such as rituximab, may be a rational treatment option for PND that does not hamper tumor immunity. © 2014 WILEY-VCH Verlag GmbH & Co.

To report two female patients with paraneoplastic cerebellar degeneration (PCD) related to breast cancer that presented with rapid eye movement-sleep behavior disorder (RBD) and improved sleep symptoms with immunotherapy. The two patients were evaluated through clinical scale and polysomnography before and after therapy with intravenous immunoglobulin. RBD was successfully treated with immunotherapy in both patients. Score on the RBD screening questionnaire dropped from 10 to 1 or 0, allied with the normalization of polysomnographic findings. A marked improvement in RBD after immunotherapy in PCD raises the hypothesis that secondary RBD may be an immune-mediated sleep disorder. © 2016 Associated Professional Sleep Societies, LLC.

We report a rare case of polyostotic fibrous dysplasia on endocrine hyperfunction with elevated human growth hormone and normal serum level of prolactin. There were some differential points of gender, gigantism, endocrine function, and GNAS gene from McCune-Albright syndrome. Malignant transformation was suspected in the pelvic tumor from imaging because rapid growth of the tumor by imaging was observed; however, no malignant change occurred in this case.

Anterior horn syndrome: A rare manifestation of primary Sjögren's syndrome.

The authors report an exceptional case of an anterior horn syndrome associated with Sjögren's syndrome in a 58-year-old patient with a flaccid tetraparesis revealed by asymmetric atrophy and diffuse fasciculations associated with xerostomia and xerophthalmia. The electroneuromyography objectified a diffuse anterior horn syndrome. The brain MRI and spinal cord were normal. Laboratory tests revealed positive anti-SSA and anti-SSB antibody. The salivary glands biopsy objectified lymphocytic sialadenitis grade 3 of Chisholm. The Schirmer's test was abnormally low. Diagnosis of anterior horn syndrome as part of Sjögren's syndrome was retained. The methylprednisolone bolus allowed partial clinical improvement after 12 months of evolution. Therefore, in patients with isolated anterior horn involvement, a correct diagnosis of the underlying SS is often delayed or overlooked entirely; in these instances, standard clinicoserological assessment is recommendable.

Unilateral facial nerve palsy is rarely encountered in Guillain-Barré syndrome (GBS). We report a case of an adolescent girl who presented with peripheral ascending weakness, preceded by Campylobacter jejuni infection. After treatment with intravenous immunoglobulin, the peripheral weakness improved. Electro-diagnostic testing confirmed axonal dysfunction and the patient was positive for antiganglioside antibodies. However, the patient developed unilateral left-sided facial weakness. She was managed with further intravenous immunoglobulin and intensive physiotherapy. The outcome for facial palsy was very good, with almost complete resolution after 2 weeks. PMID:26823357

Oncogenic osteomalacia (or tumour-induced osteomalacia) is a rare paraneoplastic syndrome caused by overproduction of fibroblastic growth factor 23 (FGF-23) by tumours. Excessive production of FGF-23 can lead to severe, symptomatic hypophosphataemia. The majority of cases have been associated with benign tumours of bone or soft tissue, such as haemangiopericytomas or other neoplasms of mesenchymal origin. We present a case of a 68-year-old woman with an FGF-23 producing B cell non-Hodgkin's lymphoma. Treatment with immunochemotherapy resulted in normalisation of serum FGF-23 and phosphate levels. 2016 BMJ Publishing Group Ltd.

Perioperative management of patients with severe hypophosphataemia secondary to oncogenic osteomalacia: Our experience and review of literature

PubMed Central

Verma, Alka; Tewari, Saipriya; Kannaujia, Ashish

2017-01-01

Oncogenic osteomalacia (OOM) is a rare paraneoplastic syndrome associated with mesenchymal tumours. It is characterised by phosphaturia, hypophosphataemia, decreased serum Vitamin D3 levels and severe osteomalacia. OOM-inducing tumours are usually benign, arising either from bone or soft tissue, with extremities and craniofacial region being the most common sites. Surgical resection of the tumour remains the mainstay of treatment. Challenges to an anaesthesiologist arise when such patients are planned for surgical resection of the underlying tumour. All the perioperative dilemmas are directly related to the severe hypophosphataemia. We describe three such cases of OOM and their perioperative management. PMID:28794533

One to two percent of all children are born with a developmental disorder requiring pediatric hospital admissions. For many such syndromes, the molecular pathogenesis remains poorly characterized. Parallel developmental disorders in other species could provide complementary models for human rare diseases by uncovering new candidate genes, improving the understanding of the molecular mechanisms and opening possibilities for therapeutic trials. We performed various experiments, e.g. combined genome-wide association and next generation sequencing, to investigate the clinico-pathological features and genetic causes of three developmental syndromes in dogs, including craniomandibular osteopathy (CMO), a previously undescribed skeletal syndrome, and dental hypomineralization, for which we identified pathogenic variants in the canine SLC37A2 (truncating splicing enhancer variant), SCARF2 (truncating 2-bp deletion) and FAM20C (missense variant) genes, respectively. CMO is a clinical equivalent to an infantile cortical hyperostosis (Caffey disease), for which SLC37A2 is a new candidate gene. SLC37A2 is a poorly characterized member of a glucose-phosphate transporter family without previous disease associations. It is expressed in many tissues, including cells of the macrophage lineage, e.g. osteoclasts, and suggests a disease mechanism, in which an impaired glucose homeostasis in osteoclasts compromises their function in the developing bone, leading to hyperostosis. Mutations in SCARF2 and FAM20C have been associated with the human van den Ende-Gupta and Raine syndromes that include numerous features similar to the affected dogs. Given the growing interest in the molecular characterization and treatment of human rare diseases, our study presents three novel physiologically relevant models for further research and therapy approaches, while providing the molecular identity for the canine conditions.

Potocki-Shaffer syndrome (PSS, OMIM #601224) is a rare contiguous gene deletion syndrome caused by haploinsufficiency of genes located on the 11p11.2p12. Affected individuals have a number of characteristic features including multiple exostoses, biparietal foramina, abnormalities of genitourinary system, hypotonia, developmental delay, and intellectual disability. We report here on the first Korean case of an 8-yr-old boy with PSS diagnosed by high resolution microarray. Initial evaluation was done at age 6 months because of a history of developmental delay, hypotonia, and dysmorphic face. Coronal craniosynostosis and enlarged parietal foramina were found on skull radiographs. At age 6 yr, he had severe global developmental delay. Multiple exostoses of long bones were detected during a radiological check-up. Based on the clinical and radiological features, PSS was highly suspected. Subsequently, chromosomal microarray analysis identified an 8.6 Mb deletion at 11p11.2 [arr 11p12p11.2 (Chr11:39,204,770-47,791,278)×1]. The patient continued rehabilitation therapy for profound developmental delay. The progression of multiple exostosis has being monitored. This case confirms and extends data on the genetic basis of PSS. In clinical and radiologic aspect, a patient with multiple exostoses accompanying with syndromic features, including craniofacial abnormalities and mental retardation, the diagnosis of PSS should be considered.

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.

Gallagher, James A; Ranganath, Lakshminarayan R; Boyde, Alan

2015-06-01

Studying severe phenotypes of rare syndromes can elucidate disease mechanisms of more common disorders and identify potential therapeutic targets. Lessons from rare bone diseases contributed to the development of the most successful class of bone active agents, the bisphosphonates. More recent research on rare bone diseases has helped elucidate key pathways and identify new targets in bone resorption and bone formation including cathepsin K and sclerostin, for which drugs are now in clinical trials. By contrast, there has been much less focus on rare cartilage diseases and osteoarthritis (OA) remains a common disease with no effective therapy. Investigation of rare cartilage syndromes is identifying new potential targets in OA including GDF5 and lubricin. Research on the arthropathy of the ultra-rare disease alkaptonuria has identified several new features of the OA phenotype, including high density mineralized protrusions (HDMPs) which constitute a newly identified mechanism of joint destruction.

Association of Dandy-Walker syndrome with occipital meningocele (OMC) is extremely rare and about thirty cases are reported till date in the Western literature. However, OMC is classified by Talamonti et al . into small, large, and giant categories with respective diameters were upto 5 cm in small, large with 5-9 cm, and giant with >9 cm. Usually the size of OMC progressively increases as raised intracranial pressure leads to compensatory cerebrospinal fluid escape into sac with the growth of children. Authors report an interesting case of an 18-month-old female child with extra-gigantic OMC, whose size was almost same since birth, representing the first case of its kind, who underwent successful surgical repair. Clinical presentation, radiological features, and surgical management options in literature are reviewed briefly for this rare disease association.

To assess the incidence and risk factors for fat embolism syndrome. Data from the National Hospital Discharge Survey (NHDS) were analyzed using International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes. From 1979 through 2005 among 928,324,000 patients discharged from short-stay hospitals in the United States, 41,000 (0.004%) had fat embolism syndrome. Among 21,538,000 patients with an isolated fracture of the femur (any site), tibia, fibula, pelvis, ribs, humerus, radius, or ulna, 25,000 (0.12%) developed fat embolism syndrome. Patients with multiple fractures of the femur (excluding neck) more often had fat embolism syndrome than those with isolated fractures (1.29% versus 0.54%). The incidence of fat embolism syndrome was lower with isolated fractures of the tibia or fibula (0.30%) and even lower with isolated fractures of the neck of the femur (0.06%). The incidence of fat embolism was too low to calculate with isolated fractures of the pelvis, ribs, humerus, radius, or ulna. Nonorthopedic conditions rarely, if ever, were accompanied by fat embolism syndrome. The fat embolism syndrome was more frequent in men (relative risk 5.71). Children, aged 0 to 9 years rarely had fat embolism syndrome. The fat embolism syndrome most commonly affected patients aged 10 to 39 years. The incidence of the fat embolism syndrome depends on the bone involved, whether fractures are isolated or multiple, the age of the patient and the gender. It rarely occurs as a result of medical conditions.

Vernet syndrome is a unilateral palsy of glossopharyngeal, vagus, and accessory nerves. Varicella zoster virus (VZV) infection has rarely been described as a possible cause. A 76-year-old man presented with 1-week-long symptoms of dysphonia, dysphagia, and weakness of the right shoulder elevation, accompanied by a mild right temporal parietal headache with radiation to the ipsilateral ear. Physical examination showed signs compatible with a right XI, X, and XI cranial nerves involvement and also several vesicular lesions in the right ear's concha. He had a personal history of poliomyelitis and chickenpox. Laringoscopy demonstrated right vocal cord palsy. Brain MRI showed thickening and enhancement of right lower cranial nerves and an enhancing nodular lesion in the ipsilateral jugular foramen, in T1 weighted images with gadolinium. Cerebrospinal fluid (CSF) analysis disclosed a mild lymphocytic pleocytosis and absence of VZV-DNA by PCR analysis. Serum VZV IgM and IgG antibodies were positive. The patient had a noticeable clinical improvement after initiation of acyclovir and prednisolone therapy. The presentation of a VZV infection with isolated IX, X, and XI cranial nerves palsy is extremely rare. In our case, the diagnosis of Vernet syndrome as a result of VZV infection was made essentially from clinical findings and supported by analytical and imaging data.

POEMS Syndrome Presentation with an Abscess within the Plasmacytoma—A Rare Case Report

POEMS Syndrome is a rare cause of demyelinating and axonal mixed neuropathy. Plasmacytomas are usually seen in POEMS syndrome and can be osseous or extramedullary. Plasmacytomas presenting as an abscess has not been noted earlier. Our patient presented with localized hyperpigmented patch on the back and later developed progressive weakness in upper and lower limbs. Initially serum and urine protein electrophoresis were normal. The patient was thought to have Chronic Inflammatory Demyelinating Polyneuropathy and was treated accordingly without any improvement. Repeat serum protein electrophoresis showed monoclonal gammopathy. MRI of the back revealed an abscess in the paravertebral soft tissues reaching up to the skin. Needle biopsy was consistent with plasmacytoma. Later, he developed a purulent fungating lesion in the lower midback. Antibiotics were started and local resection was done followed by radiation. Pathology of the resected mass showed plasmacytoma extensively involving subcutaneous soft tissue and bone. The patient improved with the treatment. Cystic plasmacytomas and abscess within the plasmacytoma has not been reported earlier. Whether abscess formation is part of the disease spectrum due to infiltration of overlying tissue or is secondary to localized immunosuppression is unknown. Local treatment of a single plasmacytoma is useful in ameliorating systemic symptoms. PMID:22084694

Hyperinsulinism, one of the most important causes of hypoglycaemia, can be congenital or acquired. Rarely, drug toxicity can be a reason for hyperinsulinism. In the context of Munchausen syndrome by proxy (MSP), toxicity usually occurs in children due to drug administration by a parent or caregiver. A 7-year-old girl was referred to our department due to a hyperglycaemic period and hypoglycaemic episodes. On admission, gliclazide was initiated due to her hyperglycaemia, which we attributed to maturity onset diabetes of the young. However, during follow-up, hypoglycaemic levels were detected. Despite cessation of gliclazide, hypoglycaemic seizures occurred. Even with the medications administered, hypoglycaemia could not be prevented. During follow-up, the mother's affect, characterized by anxiety and interest in her daughter's medical care, appeared discordant with the situation. Due to our suspicion of MSP, we discovered toxic levels of gliclazide in the blood and urine samples which had been sent to the toxicology laboratory to search for hypoglycaemic agents. The patient was isolated, and all medications were stopped. After isolation, her hypoglycaemia disappeared, and she became hyperglycaemic (250 mg/dl). Physicians should consider the possibility of MSP in hyperinsulinaemic patients with discordant laboratory results and clinical symptoms, even if the child's parents display great concern. © 2016 S.

2018-01-01

Lemierre syndrome is an uncommon condition in which internal jugular vein thrombosis presents after recent oropharyngeal infection. Frequently, this is accompanied by septic emboli. This report outlines a variant of this disease process, with septic thrombophlebitis of the neck associated with a necrotizing skin infection of the lower lip and chin. A 25-year-old man with lower lip and chin swelling, initially managed with intravenous antibiotics, progressed to the development of a left facial vein thrombus, septic emboli to the lungs, and a necrotizing lower lip and chin infection that was managed with debridement, thrombectomy, and prolonged hemodynamic and pulmonary support. A necrotizing skin infection with thrombus of the jugular system and septic emboli is a very rare variant of Lemierre syndrome. Early recognition of an infection with septic emboli and/or necrotizing pathobiological findings allows for prompt antibiotic and surgical therapy, minimizing the mortality of these potentially lethal infections.

Chromosome 22q11.2 deletion syndrome (22q11.2DS) is associated with a more than 20-fold increased risk for developing schizophrenia. The aim of this study was to identify additional genetic factors (i.e., "second hits") that may contribute to schizophrenia expression. Through an international consortium, the authors obtained DNA samples from 329 psychiatrically phenotyped subjects with 22q11.2DS. Using a high-resolution microarray platform and established methods to assess copy number variation (CNV), the authors compared the genome-wide burden of rare autosomal CNV, outside of the 22q11.2 deletion region, between two groups: a schizophrenia group and those with no psychotic disorder at age ≥25 years. The authors assessed whether genes overlapped by rare CNVs were overrepresented in functional pathways relevant to schizophrenia. Rare CNVs overlapping one or more protein-coding genes revealed significant between-group differences. For rare exonic duplications, six of 19 gene sets tested were enriched in the schizophrenia group; genes associated with abnormal nervous system phenotypes remained significant in a stepwise logistic regression model and showed significant interactions with 22q11.2 deletion region genes in a connectivity analysis. For rare exonic deletions, the schizophrenia group had, on average, more genes overlapped. The additional rare CNVs implicated known (e.g., GRM7, 15q13.3, 16p12.2) and novel schizophrenia risk genes and loci. The results suggest that additional rare CNVs overlapping genes outside of the 22q11.2 deletion region contribute to schizophrenia risk in 22q11.2DS, supporting a multigenic hypothesis for schizophrenia. The findings have implications for understanding expression of psychotic illness and herald the importance of whole-genome sequencing to appreciate the overall genomic architecture of schizophrenia.

Coarctation of the aorta (CoA) accounts for 4-8% of congenital heart defects (CHDs) and confers substantial morbidity despite treatment. It is increasingly recognized as a highly heritable condition. The aim of the study was to search for sequence variants that affect the risk of CoA. We performed a genome-wide association study of CoA among Icelanders (120 cases and 355 166 controls) based on imputed variants identified through whole-genome sequencing. We found association with a rare (frequency = 0.34%) missense mutation p.Arg721Trp in MYH6 (odds ratio = 44.2, P = 5.0 × 10-22), encoding the alpha-heavy chain subunit of cardiac myosin, an essential sarcomere protein. Approximately 20% of individuals with CoA in Iceland carry this mutation. We show that p.Arg721Trp also associates with other CHDs, in particular bicuspid aortic valve. We have previously reported broad effects of p.Arg721Trp on cardiac electrical function and strong association with sick sinus syndrome and atrial fibrillation. Through a population approach, we found that a rare missense mutation p.Arg721Trp in the sarcomere gene MYH6 has a strong effect on the risk of CoA and explains a substantial fraction of the Icelanders with CoA. This is the first mutation associated with non-familial or sporadic form of CoA at a population level. The p.Arg721Trp in MYH6 causes a cardiac syndrome with highly variable expressivity and emphasizes the importance of sarcomere integrity for cardiac development and function.

Klippel-Feil syndrome is a rare disorder represented by a subgroup of segmentation defects of the vertebrae and characterized by fusion of the cervical vertebrae, low posterior hairline, and short neck with limited motion. Both autosomal dominant and recessive inheritance patterns were reported in families with Klippel-Feil. Mutated genes for both dominant (GDF6 and GDF3) and recessive (MEOX1) forms of Klippel-Feil syndrome have been shown to be involved in somite development via transcription regulation and signaling pathways. Heterotaxy arises from defects in proteins that function in the development of left-right asymmetry of the developing embryo. We describe a consanguineous family with a male proband who presents with classical Klippel-Feil syndrome together with heterotaxy (situs inversus totalis). The present patient also had Sprengel's deformity, deformity of the sternum, and a solitary kidney. Using exome sequencing, we identified a homozygous frameshift mutation (c.299delT; p.L100fs) in RIPPLY2, a gene shown to play a crucial role in somitogenesis and participate in the Notch signaling pathway via negatively regulating Tbx6. Our data confirm RIPPLY2 as a novel gene for autosomal recessive Klippel-Feil syndrome, and in addition-from a mechanistic standpoint-suggest the possibility that mutations in RIPPLY2 could also lead to heterotaxy. © 2015 Wiley Periodicals, Inc. © 2015 Wiley Periodicals, Inc.

The Cryopyrin-Associated Periodic Syndromes (CAPS) are a group of rare hereditary autoinflammatory diseases and encompass Familial Cold Autoinflammatory Syndrome (FCAS), Muckle-Wells Syndrome (MWS), and Neonatal Onset Multisystem Inflammatory Disease (NOMID). Canakinumab is a monoclonal antibody directed against IL-1 beta and approved for CAPS patients but requires post-approval monitoring due to low and short exposures during the licensing process. Creative approaches to observational methodology are needed, harnessing novel registry strategies to ensure Health Care Provider reporting and patient monitoring. A web-based registry was set up to collect information on long-term safety and effectiveness of canakinumab for CAPS. Starting in November 2009, this registry enrolled 241 patients in 43 centers and 13 countries by December 31, 2012. One-third of the enrolled population was aged < 18; the overall population is evenly divided by gender. Enrolment is ongoing for children. Innovative therapies in orphan diseases require post-approval structures to enable in depth understanding of safety and natural history of disease. The rarity and distribution of such diseases and unpredictability of treatment require innovative methods for enrolment and follow-up. Broad international practice-based recruitment and web-based data collection are practical.

Noteworthy heterogeneity exists in the rare diseases associated with childhood glaucoma. Primary congenital glaucoma is mostly sporadic; however, 10% to 40% of cases are familial. CYP1B1 gene mutations seem to account for 87% of familial cases and 27% of sporadic cases. Childhood glaucoma is classified in primary and secondary congenital glaucoma, further divided as glaucoma arising in dysgenesis associated with neural crest anomalies, phakomatoses, metabolic disorders, mitotic diseases, congenital disorders, and acquired conditions. Neural crest alterations lead to the wide spectrum of iridocorneal trabeculodysgenesis. Systemic diseases associated with childhood glaucoma include the heterogenous group of phakomatoses where glaucoma is frequently encountered in the Sturge-Weber syndrome and its variants, in phakomatosis pigmentovascularis associated with oculodermal melanocytosis, and more rarely in neurofibromatosis type 1. Childhood glaucoma is also described in systemic disorders of mitotic and metabolic activity. Acquired secondary glaucoma has been associated with uveitis, trauma, drugs, and neoplastic diseases. A database research revealed reports of childhood glaucoma in rare diseases, which do not include glaucoma in their manifestation. These are otopalatodigital syndrome, complete androgen insensitivity, pseudotrisomy 13, Brachmann-de Lange syndrome, acrofrontofacionasal dysostosis, caudal regression syndrome, and Wolf-Hirschhorn syndrome.

Wernicke syndrome is a rare neurological pathology due to a deficit in vitamin B1. The syndrome is common among alcohol abusers, patients with malignant tumor or gastrointestinal diseases, those who undergo hemodialysis or long-term peritoneal dialysis, pregnant women with hyperemesis, women who breast-feed, patients with hyperthyroidism or anorexia nervosa or gastric or jejunal-ileal bypass surgery for obesity, patients submitted to gastric surgery or prolonged total parenteral nutrition or prolonged intravenous therapy. We report a case of Wernicke syndrome due to afferent loop syndrome characterized by incoercible vomiting.

The “Neuro” of Neuroblastoma: Neuroblastoma as a Neurodevelopmental Disorder

Neuroblastoma is a childhood cancer derived from cells of neural crest origin. The hallmarks of its enigmatic character include its propensity for spontaneous regression under some circumstances and its association with paraneoplastic opsoclonus, myoclonus, and ataxia. The neurodevelopmental underpinnings of its origins may provide important clues for development of novel therapeutic and preventive agents for this frequently fatal malignancy and for the associated paraneoplastic syndromes.

2017-01-01

Cancer anorexia-cachexia syndrome (CACS) is a complex and largely untreatable paraneoplastic complication common in advanced cancer. It is associated with profoundly deleterious effects on quality of life and survival. Since its discovery over a decade ago, anamorelin hydrochloride (anamorelin), a mimetic of the growth hormone secretagogue ghrelin, has shown considerable promise in ameliorating components of CACS when administered to patients with advanced cancer, including loss of lean body mass and reversal of anorexia. This review summarizes the development of anamorelin and its safety and efficacy in clinical investigations. The potential future role of anamorelin in treating CACS is also discussed.

Remitting seronegative symmetrical synovitis with pitting edema or RS3PE is a rare elderly-onset rheumatic syndrome. Although there are overlapping clinical manifestations between RS3PE, elderly-onset rheumatoid arthritis, and polymyalgia rheumatica, RS3PE has distinct characteristics. RS3PE can be associated with neoplasia and various rheumatic conditions, suggesting that it may be heterogeneous, and is considered as a paraneoplastic rheumatic disease. The pathogenesis of RS3PE may involve vascular endothelial growth factor and infection in RS3PE based upon limited data. Patients with RS3PE without concomitant malignancy respond well to small doses of glucocorticoids and carry good prognosis.

A thymic neuroendocrine tumour in a young female: a rare cause of relapsing and remitting Cushing's syndrome.

PubMed

Trott, M J; Farah, G; Stokes, V J; Wang, L M; Grossman, A B

2016-01-01

We present a case of a young female patient with a rare cause of relapsing and remitting Cushing's syndrome due to ectopic ACTH secretion from a thymic neuroendocrine tumour. A 34-year-old female presented with a constellation of symptoms of Cushing's syndrome, including facial swelling, muscle weakness and cognitive impairment. We use the terms 'relapsing and remitting' in this case report, given the unpredictable time course of symptoms, which led to a delay of 2 years before the correct diagnosis of hypercortisolaemia. Diagnostic workup confirmed ectopic ACTH secretion, and a thymic mass was seen on mediastinal imaging. The patient subsequently underwent thymectomy with complete resolution of her symptoms. Several case series have documented the association of Cushing's syndrome with thymic neuroendocrine tumours (NETs), although to our knowledge there are a few published cases of patients with relapsing and remitting symptoms. This case is also notable for the absence of features of the MEN-1 syndrome, along with the female gender of our patient and her history of non-smoking. Ectopic corticotrophin (ACTH) secretion should always be considered in the diagnostic workup of young patients with Cushing's syndromeThere is a small but growing body of literature describing the correlation between ectopic ACTH secretion and thymic neuroendocrine tumours (NETs)The possibility of a MEN-1 syndrome should be considered in all patients with thymic NETs, and we note the observational association with male gender and cigarette smoking in this cohortAn exception to these associations is the finding of relatively high incidence of thymic NETs among female non-smoking MEN-1 patients in the Japanese compared with Western populationsThe relapsing and remitting course of our patient's symptoms is noteworthy, given the paucity of this finding among other published cases.

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.

Anti-Yo paraneoplastic cerebellar degeneration (PCD) is a devastating autoimmune complication of gynecological cancers. We hypothesized that as for other autoimmune diseases, specific HLA haplotypes are associated. We conducted high resolution HLA typing of Class I/Class II in 40 cases versus ethnically matched controls. Three cases with anti-Yo antibodies and peripheral neuropathy were also included. We detected protective effects of DPA1*01:03~DPB1*04:01 (OR=0, p=0.0008), DRB1*04:01~DQA1*03:03(OR=0, p=0.0016) and DPA1*01:03~DPB1*04:01 (OR=0.35, p=0.0047) overall. Increased DRB1*13:01~DQA1*01:03~DQB1*06:03 was also found in PCD ovarian cases (OR=5.4, p=0.0016). These results suggest differential genetic susceptibility to anti-Yo per cancer and with a primary HLA Class II involvement. Copyright © 2017 Elsevier B.V. All rights reserved.

Myasthenia and related disorders of the neuromuscular junction.

Spillane, Jennifer; Beeson, David J; Kullmann, Dimitri M

2010-08-01

Our understanding of transmission at the neuromuscular junction has increased greatly in recent years. We now recognise a wide variety of autoimmune and genetic diseases that affect this specialised synapse, causing muscle weakness and fatigue. These disorders greatly affect quality of life and rarely can be fatal. Myasthenia gravis is the most common disorder and is most commonly caused by autoantibodies targeting postsynaptic acetylcholine receptors. Antibodies to muscle-specific kinase (MuSK) are detected in a variable proportion of the remainder. Treatment is symptomatic and immunomodulatory. Lambert-Eaton myasthenic syndrome is caused by antibodies to presynaptic calcium channels, and approximately 50% of cases are paraneoplastic, most often related to small cell carcinoma of the lung. Botulism is an acquired disorder caused by neurotoxins produced by Clostridium botulinum, impairing acetylcholine release into the synaptic cleft. In addition, several rare congenital myasthenic syndromes have been identified, caused by inherited defects in presynaptic, synaptic basal lamina and postsynaptic proteins necessary for neuromuscular transmission. This review focuses on recent advances in the diagnosis and treatment of these disorders.

DRESS syndrome with thrombotic microangiopathy revealing a Noonan syndrome

PubMed Central

Bobot, Mickaël; Coen, Matteo; Simon, Clémentine; Daniel, Laurent; Habib, Gilbert; Serratrice, Jacques

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

Meigs syndrome is a rare complication associated with ovarian fibromas. Although ovarian fibromas are rare in children, they are common in women with Gorlin syndrome after puberty. A 14-year-old girl with Gorlin syndrome was admitted to our hospital for ablation of basal cell carcinoma. A chest x-ray revealed pleural effusion. Ultrasonography revealed bilateral multinodular ovarian masses. Meigs syndrome associated with ovarian fibromas was considered. A laparotomy revealed bilateral ovarian masses, which were resected. Microscopically, the masses were composed of mitotically active fibroma and areas resembling hemangiopericytoma and luteinized thecoma. The pleural effusion disappeared soon after the surgery. Physicians should consider the possibility that pleural effusion might precede the diagnosis of ovarian fibroma in patients with Gorlin syndrome.

Only few cases of nephrotic syndrome associated with Guillain-Barre Syndrome (GBS) have been reported in the adult and pediatric literature. A 3-year-old boy was initially admitted to our hospital following five days of progressive weakness of his extremities, fatigue, right leg pain and numbness. There was no past history of renal or neurological disease. Cerebro-spinal fluid studies showed a protein level of 92 mg/dL and a white cell count of 1 per high-power field. The diagnosis of GBS was verified with a nerve conduction velocity test as well as. The GBS symptoms improved gradually on intravenous immunoglobulin. Three weeks later, he developed severe proteinuria and edema; laboratory investigation showed nephrotic syndrome which responded to steroid therapy. Renal biopsy showed minimal change glomerulonephritis. He remained free of proteinuria during his 20 months of follow-up.

Behçet's disease (BD) is a multisystemic disorder that involves vessels of all sizes. Superior vena cava (SVC) thrombosis is a rare complication that can lead to the development of various collateral pathways. A 31-year-old man presented with SVC syndrome. He had a history of recurrent genital aphthosis. Computed tomography revealed extensive thrombosis of the right internal jugular, axillary, and subclavian veins with collateral circulation. The patient was diagnosed with BD, and he was started on anticoagulation and immunosuppressive therapy. One week later, he presented with haematemesis. Upper gastrointestinal endoscopy disclosed varices in the upper third of the oesophagus with stigmata of recent bleeding. Portal hypertension was ruled out. Anticoagulation therapy was discontinued. He was discharged on immunosuppressive therapy. Bleeding from downhill oesophageal varices should be suspected in any patient presenting with upper gastrointestinal bleeding and a history of SVC syndrome due to BD.

Purpose. Electronic health record systems provide great opportunity to study most diseases. Objective of this study was to determine whether electronic medical records (EMR) in ophthalmology contribute to management of rare eye diseases, isolated or in syndromes. Study was designed to identify and collect patients' data with ophthalmology-specific EMR. Methods. Ophthalmology-specific EMR software (Softalmo software Corilus) was used to acquire ophthalmological ocular consultation data from patients with five rare eye diseases. The rare eye diseases and data were selected and collected regarding expertise of eye center. Results. A total of 135,206 outpatient consultations were performed between 2011 and 2014 in our medical center specialized in rare eye diseases. The search software identified 29 congenital aniridia, 6 Axenfeld/Rieger syndrome, 11 BEPS, 3 Nanophthalmos, and 3 Rubinstein-Taybi syndrome. Discussion. EMR provides advantages for medical care. The use of ophthalmology-specific EMR is reliable and can contribute to a comprehensive ocular visual phenotype useful for clinical research. Conclusion. Routinely EMR acquired with specific software dedicated to ophthalmology provides sufficient detail for rare diseases. These software-collected data appear useful for creating patient cohorts and recording ocular examination, avoiding the time-consuming analysis of paper records and investigation, in a University Hospital linked to a National Reference Rare Center Disease.

A case is reported of an eight-month-old female patient who had traditional uvulectomy for sore throat complicated by Grisel's syndrome. She was admitted into the hospital one week after uvulectomy with Torticolis. Grisel's syndrome is a nontraumatic atlantoaxial subluxation, usually secondary of an infection or an inflammation at the head and neck area, or after surgery in the same area. Patients typically suffer from painful torticollis. Diagnosis of Grisel's syndrome is largely based on suspicion of the patient who has recently undergone surgery or has a history of an infection in head and neck area. Physical examination and imaging techniques assist in diagnosis. Thus, clinicians should be aware of acute nontraumatic torticollis if patient had a recent surgery in the head or neck area or undergone an upper respiratory tract infection. In this paper, a case of an eight-month-old female patient who had Grisel's syndrome after uvulectomy is discussed. This case is reported to highlight this neurogical threatening complication following traditional uvulectomy as well as highlighting the unnecessary morbidity and mortality associated with this persisting mode of treatment in Africa.

Kindler syndrome is a rare autosomal recessive disorder associated with skin fragility. It is characterized by blistering in infancy, photosensitivity and progressive poikiloderma. The syndrome involves the skin and mucous membrane with radiological changes. The genetic defect has been identified on the short arm of chromosome 20. This report describes an 18-year-old patient with classical features like blistering and photosensitivity in childhood and the subsequent development of poikiloderma. The differential diagnosis of Kindler syndrome includes diseases like Bloom syndrome, Cockayne syndrome, dyskeratosis congenita, epidermolysis bullosa, Rothmund-Thomson syndrome and xeroderma pigmentosum. Our patient had classical cutaneous features of Kindler syndrome with phimosis as a complication.

Renal hemangiopericytoma secondary to refractory hypertension in a child: A case report.

Hu, Qingfeng; Fang, Zujun; Zhou, Zhongwen; Zheng, Jie

2014-12-01

Hemangiopericytoma is a rare perivascular tumor that often involves the extremities, pelvis, head and neck, and meninges, but rarely occurs in the kidney. The differentiation from renal cancer prior to surgery is extremely challenging; therefore, almost all cases of renal hemangiopericytoma are diagnosed by pathological examination. The majority of cases are identified in patients between the ages of 20 and 50 years of age, and a considerable proportion of patients exhibit hypertension, hypoglycaemia or additional paraneoplastic syndromes. The current study reports a rare case of renal hemangiopericytoma with drug refractory hypertension in a 14-year-old female. Following the complete resection of the tumor, the patient's blood pressure returned to normal. No evidence of recurrence or metastasis was observed during a follow-up of 12 months following surgery. The present case indicated that surgery provides satisfactory outcomes and appears to be the most effective modality of treatment for renal hemangiopericytoma. Furthermore, this case also demonstrated that secondary hypertension may also recover following tumor excision.

Approximately half of the familial aggregation of breast cancer remains unexplained. A multiple-case breast cancer family exome sequencing study identified three likely pathogenic mutations in RINT1 (NM_021930.4) not present in public sequencing databases: RINT1 c.343C>T (p.Q115X), c.1132_1134del (p.M378del) and c.1207G>T (p.D403Y). Based on this finding, a population-based case-control mutation-screening study was conducted and identified 29 carriers of rare (MAF < 0.5%), likely pathogenic variants: 23 in 1,313 early-onset breast cancer cases and 6 in 1,123 frequency-matched controls (OR=3.24, 95%CI 1.29-8.17; p=0.013). RINT1 mutation screening of probands from 798 multiple-case breast cancer families identified 4additional carriers of rare genetic variants. Analysis of the incidence of first primary cancers in families of women in RINT1-mutation carrying families estimated that carriers were at increased risks of Lynch syndrome-spectrum cancers (SIR 3.35, 95% CI 1.7-6.0; P=0.005), particularly for relatives diagnosed with cancer under age 60 years (SIR 10.9, 95%CI 4.7-21; P=0.0003).

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.

What, if anything, is specific about having a rare disorder? Patients’ judgements on being ill and being rare

Abstract Background  Growing efforts are made to improve the situation of persons with rare diseases, but the specific nature of these disorders remains unclear. Objectives  To establish (1) to what extent people with rare disorders think that their disease’s rarity causes particular difficulties, (2) to what extent these difficulties relate to other causes than rarity (i.e. other characteristics of the disease or other components of the illness experience), (3) to what extent the rarity of the disease may relate to components of patients’ experience other than those that are traditionally addressed (i.e. personal or daily life aspects). Methods  Semi‐structured interviews with 29 patients and 15 parents of children with one of six rare diseases (cystic fibrosis, fragile X syndrome, Wilson’s disease, mastocytosis, locked‐in syndrome and a sixth syndrome). The interviews were conducted in France. The analysis draws on French pragmatic sociology and focuses on the participants’ judgements of their experience. Findings  The participants considered as normal and acceptable a range of situations that are often viewed as specific to rare disorders and unfair. This rather positive evaluation was conditional on some specific moral criteria being met. The participants attributed the cause of their difficulties to the failure of health professionals to meet these criteria. In the participants’ experience, disease‐related associations play a key role and rarity seems to contribute to making them especially important. Conclusions  Patients’ experience would be considerably improved if health professionals more often fulfilled their moral expectations, especially regarding diagnosis disclosure and information.

The pemphigus group comprises the autoimmune intraepidermal blistering diseases classically divided into two major types: pemphigus vulgaris and pemphigus foliaceous. Pemphigus herpetiformis, IgA pemphigus, paraneoplastic pemphigus and IgG/IgA pemphigus are rarer forms that present some clinical, histological and immunopathological characteristics that are different from the classical types. These are reviewed in this article. Future research may help definitively to locate the position of these forms in the pemphigus group, especially with regard to pemphigus herpetiformis and the IgG/ IgA pemphigus. PMID:24626654

DRESS syndrome with thrombotic microangiopathy revealing a Noonan syndrome: Case report.

PubMed

Bobot, Mickaël; Coen, Matteo; Simon, Clémentine; Daniel, Laurent; Habib, Gilbert; Serratrice, Jacques

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.

Rare nocturnal headaches.

Cohen, Anna S; Kaube, Holger

2004-06-01

This review describes rare headaches that can occur at night or during sleep, with a focus on cluster headaches, paroxysmal hemicrania, short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing, hypnic headache and exploding head syndrome. It is known that cluster headaches and hypnic headache are associated with rapid eye movement sleep, as illustrated by recent polysomnographic studies. Functional imaging studies have documented hypothalamic activation that is likely to be of relevance to circadian rhythms. These headache syndromes have been shown to respond to melatonin and lithium therapy, both of which have an indirect impact on the sleep-wake cycle. There is growing evidence that cluster headache and hypnic headache are chronobiological disorders.

Since the initial description of limbic encephalitis (LE) in 1960/1968, several subforms of this clinico-neuropathological syndrome have been identified. The best known is paraneoplastic LE. However, non-paraneoplastic forms have been reported, too. Very recently, autoantibodies against voltage-gated potassium channels have been described in association with LE. The diagnostic workup of such a case and the apparently typical good response to long-term immunotherapy of this LE subform are described.

Kenny-Caffey syndrome (KCS) is a very rare dysmorphologic syndrome characterized by proportionate short stature, cortical thickening and medullary stenosis of tubular bones, delayed closure of anterior fontanelle, eye abnormalities, and hypoparathyroidism. Two types of KCS were known: the autosomal recessive form (KCS type 1), which is caused by mutations of the TBCE gene, and the autosomal dominant form (KCS type 2), which is caused by mutations of the FAM111A gene. TBCE mutation also causes hypoparathyroidism-retardation-dysmorphism syndrome, and FAM111A mutation also causes gracile bone dysplasia. These two diseases can be called as KCS-related syndromes. In this article, we review the clinical manifestations of KCS and discuss its related syndromes.

The association between cancer and immune-mediated rheumatic conditions is controversial, especially as far as polymyalgia rheumatica (PMR) is concerned. Furthermore, no clinical feature has been shown to be suggestive of a paraneoplastic rheumatic syndrome. With the present study, we aim to address both these issues. The study population comprised N = 1750 patients, including N = 100 with PMR, who attended our tertiary immuno-rheumatology clinic between January 1, 2005 and November 30, 2012. A rheumatic disease was deemed paraneoplastic if cancer had been diagnosed in the 2 years preceding or following its onset. The probability of a significant association between a specific rheumatic disease and cancer was evaluated by computing the odds ratio (OR): N = 702 patients with osteoarthritis serving as controls. Furthermore, clinical features distinguishing paraneoplastic rheumatic diseases were searched for by univariate and multivariate analysis. Sjogren's syndrome (SS) [OR 3.6 (CI 95% 1.7-7.5)], PMR (OR 5.1 CI 95% 2.9-8.9), dermatomyositis/polymyositis [OR 12.09 (CI 95% 2.6-55.8)] and vasculitis [OR 3.70 (CI 95% 1.81-7.52)] are associated with cancer. At multivariate analysis, older age is associated with cancer among SS patients (p = 0.03), while in the PMR group, older age, male gender, and ≥6 tender joints are independent predictors of paraneoplastic PMR (p < 0.0004). Cancer frequently either heralds or follows rheumatic manifestations, including PMR. Older age, male gender and a more extensive joint involvement should be considered red flags for paraneoplastic PMR.

[Anorectal pain in children: rare or rarely recognised?].

PubMed

Sonneveld, Laura J H; Engelberts, Adèle C; van den Elzen, Annette P M

2016-01-01

Anorectal pain is a common symptom, often as part of functional gastrointestinal disorders. Children seldom present with this complaint. Proctalgia fugax and chronic proctalgia are both anorectal pain syndromes but differ in duration and frequency of episodes and in pain characteristics. No research has been conducted on anorectal pain syndromes in children. We present two patients. Firstly, an 8-year-old girl who suffered from anorectal cramps. We found no underlying cause apart from constipation. The symptoms disappeared spontaneously. The second concerned an 8-year-old boy who presented with recurrent anorectal cramps. He was diagnosed with celiac disease. Anorectal dysfunction and visceral hypersensitivity have been described in adult celiac patients. Symptoms of anorectal pain in children are rare probably because it often remains unrecognised. Noninvasive diagnostic methods and interventions are preferred in paediatric medicine. Screening for celiac disease in children with anorectal pain episodes should be considered.

Movement and Other Neurodegenerative Syndromes in Patients with Systemic Rheumatic Diseases

2015-01-01

Abstract Patients with rheumatic diseases can present with movement and other neurodegenerative disorders. It may be underappreciated that movement and other neurodegenerative disorders can encompass a wide variety of disease entities. Such disorders are strikingly heterogeneous and lead to a wider spectrum of clinical injury than seen in Parkinson's disease. Therefore, we sought to stringently phenotype movement and other neurodegenerative disorders presenting in a case series of rheumatic disease patients. We integrated our findings with a review of the literature to understand mechanisms which may account for such a ubiquitous pattern of clinical injury. Seven rheumatic disease patients (5 Sjögren's syndrome patients, 2 undifferentiated connective tissue disease patients) were referred and could be misdiagnosed as having Parkinson's disease. However, all of these patients were ultimately diagnosed as having other movement or neurodegenerative disorders. Findings inconsistent with and more expansive than Parkinson's disease included cerebellar degeneration, dystonia with an alien-limb phenomenon, and nonfluent aphasias. A notable finding was that individual patients could be affected by cooccurring movement and other neurodegenerative disorders, each of which could be exceptionally rare (ie, prevalence of ∼1:1000), and therefore with the collective probability that such disorders were merely coincidental and causally unrelated being as low as ∼1-per-billion. Whereas our review of the literature revealed that ubiquitous patterns of clinical injury were frequently associated with magnetic resonance imaging (MRI) findings suggestive of a widespread vasculopathy, our patients did not have such neuroimaging findings. Instead, our patients could have syndromes which phenotypically resembled paraneoplastic and other inflammatory disorders which are known to be associated with antineuronal antibodies. We similarly identified immune-mediated and inflammatory markers

POEMS syndrome is a paraneoplastic syndrome caused by an underlying plasma cell proliferative disease. In this study, we examined the treatment outcomes and role of radiotherapy in the management of POEMS syndrome. In total, 33 patients diagnosed with POEMS syndrome were analyzed. These patients presented with osteosclerotic myeloma (OSM, n = 13), Castleman's disease (CD, n = 4), OSM with CD (n = 10), and vascular endothelial growth factor elevation without gross lesions (VEGFe, n = 6), respectively. The patients were treated by radiotherapy alone (n = 4), chemotherapy alone (n = 16), or a combination thereof (n = 9). The clinical response rates of radiotherapy, chemotherapy, and radiotherapy plus chemotherapy were 75%, 69%, and 89%, respectively. In addition, the hematologic response rates were 50%, 69%, and 71%, respectively. Among the six patients with limited multiple lesions who underwent radiotherapy, the clinical symptoms were improved in five patients after radiotherapy. The median progression-free survival (PFS) was 51 months, and the median overall survival (OS) was 65 months. In univariate analysis, the administration of chemotherapy was significantly associated with better PFS (p = 0.007) and OS (p = 0.020). In contrast, underlying VEGFe was a significant factor worsening PFS (p = 0.035) and OS (p = 0.008). Radiotherapy produces a reliable clinical response and is effective in improving POEMS-associated symptoms that are refractory to chemotherapy in selected patients with clustered or limited multiple lesions that can be covered by single radiation field.

Aberrant Muscle Syndrome (AMS) is a rare congenital hand difference that is characterised by unilateral non-progressive muscular hyperplasia. The aetiology of aberrant muscle syndrome is not known, but a recently published case has shown a somatic PIK3CA activating mutation in a patient with AMS. Carpal tunnel syndrome (CTS) in children is rare. The most common causes are the mucopolysaccaridoses but space-occupying lesions have also been reported to cause CTS in children. We report the first case of CTS in a child with AMS successfully treated with open carpal tunnel release and excision of aberrant muscles.

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.

Kindler syndrome is a rare autosomal recessive genodermatosis belonging to the class of bullous poikiloderma. Corneal lesions are rare. We report a case of ocular lesions in this syndrome. We report the case of a 57-year-old patient followed since childhood in dermatology with the diagnosis of Kindler syndrome. He presented to the ophthalmology department with decreased vision. Ophthalmologic examination showed symblepharon, ectropion in both eyes, and corneal deformation. The role played by the abnormal protein in epithelial integrity suggests that ocular and more particularly corneal involvement is not rare in Kindler syndrome. In fact, it is less known by ophthalmologists and dermatologists are not aware of the ophthalmologic manifestations. Copyright © 2011 Elsevier Masson SAS. All rights reserved.

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.

The Gorlin-Goltz syndrome (GGS) (the nevoid basal cell carcinoma syndrome-NBCCS) is a rare autosomal dominant syndrome caused due to mutations in the PTCH (patched) gene found on chromosome arm 9q. The syndrome, characterized by increased predisposition to develop basal cell carcinoma and associated multiorgan anomalies, has a high level of penetrance and variable expressiveness. GGS is a multidisciplinary problem, early diagnosis of which allows introduction of secondary prophylaxis and following an appropriate treatment to delay the progress of the syndrome. The following report emphasizes the need for awareness of the diagnostic criteria of this syndrome in cases with no typical skin lesions.

The Brugada syndrome (BrS) is a rare heritable cardiac arrhythmia disorder associated with ventricular fibrillation and sudden cardiac death. Mutations in the SCN5A gene have been causally related to BrS in 20-30% of cases. Twenty other genes have been described as involved in BrS, but their overall contribution to disease prevalence is still unclear. This study aims to estimate the burden of rare coding variation in arrhythmia-susceptibility genes among a large group of patients with BrS. We have developed a custom kit to capture and sequence the coding regions of 45 previously reported arrhythmia-susceptibility genes and applied this kit to 167 index cases presenting with a Brugada pattern on the electrocardiogram as well as 167 individuals aged over 65-year old and showing no history of cardiac arrhythmia. By applying burden tests, a significant enrichment in rare coding variation (with a minor allele frequency below 0.1%) was observed only for SCN5A, with rare coding variants carried by 20.4% of cases with BrS versus 2.4% of control individuals (P = 1.4 × 10(-7)). No significant enrichment was observed for any other arrhythmia-susceptibility gene, including SCN10A and CACNA1C. These results indicate that, except for SCN5A, rare coding variation in previously reported arrhythmia-susceptibility genes do not contribute significantly to the occurrence of BrS in a population with European ancestry. Extreme caution should thus be taken when interpreting genetic variation in molecular diagnostic setting, since rare coding variants were observed in a similar extent among cases versus controls, for most previously reported BrS-susceptibility genes. © The Author 2015.

Brittle cornea syndrome 1 (BCS1) is a rare recessive condition characterized by extreme thinning of the cornea and sclera, caused by mutations in ZNF469. Keratoconus is a relatively common disease characterized by progressive thinning and ectasia of the cornea. The etiology of keratoconus is complex and not yet understood, but rare ZNF469 variants have recently been associated with disease. We investigated the phenotype of BCS1 carriers with known pathogenic ZNF469 mutations, and recruited families in which aggregation of keratoconus was observed to establish if rare variants in ZNF469 segregated with disease. Patients and family members were recruited and underwent comprehensive anterior segment examination, including corneal topography. Blood samples were donated and genomic DNA was extracted. The coding sequence and splice sites of ZNF469 were PCR amplified and Sanger sequenced. Four carriers of three BCS1-associated ZNF469 loss-of-function mutations (p.[Glu1392Ter], p.[Gln1930Argfs*6], p.[Gln1930fs*133]) were examined and none had keratoconus. One carrier had partially penetrant features of BCS1, including joint hypermobility. ZNF469 sequencing in 11 keratoconus families identified 9 rare (minor allele frequency [MAF] ≤ 0.025) variants predicted to be potentially damaging. However, in each instance the rare variant(s) identified, including two previously reported as potentially keratoconus-associated, did not segregate with the disease. The presence of heterozygous loss-of-function alleles in the ZNF469 gene did not cause keratoconus in the individuals examined. None of the rare nonsynonymous ZNF469 variants identified in the familial cohort conferred a high risk of keratoconus; therefore, genetic variants contributing to disease pathogenesis in these 11 families remain to be identified.

Rare disease patients are the predominant group of patients who are now connecting online to patient support groups, yet research on their uses of support groups has received little attention. This is a content analysis of three vascular diseases of differing degrees of rarity. Wall posts from Facebook patient support groups for May Thurner syndrome, thoracic outlet syndrome, and superior mesenteric artery syndrome were analyzed over a period of two years. Using Uses and Gratifications as the theoretical framework, the study purpose was to assess how variations in health condition and rarity of condition affect online support group user needs. Results indicated common main cognitive and affective uses across conditions, indicating a consistent pattern of needs communicated by all patients. However, there were nuanced differences in subcategories of cognitive and affective uses between the most and least rare disorders, which inform areas for tailored support mechanisms. Additionally, these vascular patients used their respective support groups primarily for cognitive reasons, especially for the rarest conditions, which informs of basic medical informational needs these patients face related to tests, treatment, surgery, and diagnoses.

The Colorado Neurological Institute Movement Disorders Center in Englewood, Colorado, and the Mayo Clinic in Rochester, Minnesota. A 55-year-old man with a paraneoplastic neurological disorder characterized by rapid eye movement sleep behavior disorder, narcolepsy, and a progressive supranuclear palsy-like syndrome in the setting of tonsillar carcinoma. Immunotherapy for paraneoplastic neurological disorder, surgery and radiotherapy for cancer, and symptomatic treatment for parkinsonism and sleep disorders. Polysomnography, multiple sleep latency test, and neurological examination. The cancer was detected at a limited stage and treatable. After oncological therapy and immunotherapy, symptoms stabilized. Treatment with modafinil improved daytime somnolence. Rapid onset and progression of multifocal deficits may be a clue to paraneoplastic etiology. Early treatment of a limited stage cancer (with or without immunotherapy) may possibly slow progression of neurological symptoms. Symptomatic treatment may be beneficial.

Introduction Multiple endocrine neoplasia 1 (MEN1) is a cancer syndrome resulting from mutations of the MEN1 gene. The syndrome is characterized by neoplasia of the parathyroid and pituitary glands, and malignant tumors of the endocrine pancreas. Other manifestations include benign lipomas, angiofibromas, and carcinoid tumors commonly originating in the colon, thymus, and lung. This is the first report of MEN1 syndrome manifesting as bilateral granulosa cell ovarian tumors, and which is associated with a rare intronic mutation of the MEN1 gene. Case report A 41-year-old woman presented with abdominal pain, increasing abdominal girth, and dysmenorrhea. Ultrasound demonstrated enlarged ovaries and uterine fibroids. After an exploratory laparotomy, she subsequently underwent bilateral salpingo–oophorectomy with hysterectomy where the pathology revealed bilateral cystic granulosa cell tumors of the ovaries. Additional workup including computed tomography imaging discovered a thymic mass, which the pathology showed was malignant, along with a pancreatic mass suspicious for a neuroendocrine tumor. Hyperparathyroidism was also discovered and was found to be secondary to a parathyroid adenoma. Genetic testing revealed an exceedingly rare mutation in the MEN1 gene (c.654 + 1 G>A). Discussion Mutations of the menin gene leading to MEN1 syndrome are classically nonsense or missense mutations producing a dysfunctional protein product. Recently, researchers described a novel mutation of MEN1 (c.654 + 1 G>A) in a male proband meeting the criteria for clinical MEN1 syndrome. Functional analysis performed on the stable mutant protein showed selective disruption of the transforming growth factor beta signaling pathway, yet it maintained its wild-type ability to inhibit nuclear factor kappa B and to suppress JunD transcriptional activity. Conclusion To our knowledge, this is the first report of MEN1 syndrome associated with bilateral granulosa cell malignancy. We postulate that

Unique Migraine Subtypes, Rare Headache Disorders, and Other Disturbances.

The medical aphorism that common things happen commonly makes unique (and less common) migraine subtypes especially appropriate to review for the general neurologist. This article also identifies some rare headache disorders and other disturbances, and offers strategies to manage them. This article discusses migraine with brainstem aura, which is troublesome clinically and has had a change in terminology in the International Classification of Headache Disorders, Third Edition, beta version (ICHD-3 beta), and hemiplegic migraine, which is also troublesome in practice. The rare headache disorder hypnic headache and the exploding head syndrome are also discussed. When hypnic headache is recognized, it is eminently treatable, while exploding head syndrome is a benign condition with no reported consequences. Unique migraine subtypes, rare headache disorders, and other disturbances present to neurologists. When recognized, they can often be managed very well, which offers significant benefits to patients and practice satisfaction to neurologists.

We aimed to evaluate the prevalence of antineuronal antibodies in a nationwide cohort of patients with encephalopathy of unknown etiology. We screened 1699 patients with idiopathic encephalopathy who were referred from 70 hospitals across Korea for autoimmune synaptic and classic paraneoplastic antibodies. Those with cerebellar degeneration, sensory polyneuropathy or other paraneoplastic syndromes without encephalopathy were not included in this study. One-hundred and four patients (6.12%) had antibody-associated autoimmune encephalopathy. Autoimmune synaptic antibodies were identified in 89 patients (5.24%) and classic paraneoplastic antibodies were identified in 16 patients (0.94%). The patients with antibody-associated autoimmune encephalopathy comprised a small but significant portion of the total number of patients with encephalopathy of unknown cause.

Stiff Person Syndrome (SPS) is a rare autoimmune neurological disorder characterized by progressive stiffness and rigidity of truncal muscles accompanied with co-contraction of agonist-antagonist muscles. Our 51-year-old female patient was presented for the first time to physiatrists in 2006 and diagnosed with axial-spondyloarthropathy (SpA) HLA-B27 positive. SPS was diagnosed 7 years after initial symptoms. SPS should be taken into consideration in HLA-B27 positive patients if stiffness of paravertebral and abdominal muscles progresses during SpA therapy.

2006-03-01

Spontaneous arterial dissection in peripheral arteries of the extremities is an extremely rare event. We report a case of a spontaneous dissection of a nonaneurysmal popliteal artery in an otherwise healthy 36-year-old man that came to clinical attention as an acute blue toe syndrome. The diagnosis was primarily made by high-resolution duplex ultrasound that revealed a dissection flap (length: 15.5 mm; thickness: 0.4 mm) together with the partially thrombosed false lumen at the dorsal wall of the left popliteal artery (degree of local diameter reduction: 56%). Further work-up by means of contrast-enhanced MR-A and conventional DSA confirmed a moderate stenosis of the popliteal artery compatible with focal dissection and excluded other causes such as popliteal artery entrapment syndrome. Under full-dose intravenous anticoagulation with unfractionated heparin that was switched to oral anticoagulation with vitamin K antagonists (target INR: 2-3) and conservative management of the blue toe the patient made a gradual, but eventually complete clinical recovery over 8 weeks.

2014-01-01

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.

Proteus syndrome is a rare syndrome characterized by disproportionate overgrowth of limbs, multiple hamartomas, and vascular malformations. The cerebriform connective tissue nevi, also called cerebriform plantar hyperplasia, are present in most patients, and is the main characteristic of the syndrome. If present, even alone, they can be considered as a pathognomonic sign. This article reports a classic case of Proteus syndrome in a 2-year-old male patient who began to show a discrete asymmetry of the right hemibody in relation to the left one after birth, which increased over the months. He also showed cerebriform plantar hyperplasia and Port-wine stains, among other alterations. PMID:29166516

2016-01-01

47 XXY/46 XX mosaicism with characteristics suggesting Klinefelter syndrome is very rare and at present, only seven cases have been reported in the literature. We report an Indian boy diagnosed as variant of Klinefelter syndrome with 47 XXY/46 XX mosaicism at age 12 years. He was noted to have right cryptorchidism and chordae at birth, but did not have surgery for these until age 3 years. During surgery, the right gonad was atrophic and removed. Histology revealed atrophic ovarian tissue. Pelvic ultrasound showed no Mullerian structures. There was however no clinical follow up and he was raised as a boy. At 12 years old he was re-evaluated because of parental concern about his 'female' body habitus. He was slightly overweight, had eunuchoid body habitus with mild gynaecomastia. The right scrotal sac was empty and a 2mls testis was present in the left scrotum. Penile length was 5.2 cm and width 2.0 cm. There was absent pubic or axillary hair. Pronation and supination of his upper limbs were reduced and x-ray of both elbow joints revealed bilateral radioulnar synostosis. The baseline laboratory data were LH < 0.1 mIU/ml, FSH 1.4 mIU/ml, testosterone 0.6 nmol/L with raised estradiol, 96 pmol/L. HCG stimulation test showed poor Leydig cell response. The karyotype based on 76 cells was 47 XXY[9]/46 XX[67] with SRY positive. Laparoscopic examination revealed no Mullerian structures. Insisting on an adequate number of cells (at least 50) to be examined during karyotyping is important so as not to miss diagnosing mosaicism.

2013-01-01

VogtKoyanagi-Harada (VKH) is a rare syndrome affecting tissues with melanocytes. The possibility that VKH syndrome has an autoimmune pathogenesis is supported by the high frequency of human leukocyte antigen-DR4 commonly associated with other autoimmune diseases. Eyes are the main affected organ, resulting in blindness. Brain disease as a late onset event is extremely rare. Here, we are reporting a 57-year-old woman with previously diagnosed VKH syndrome, presenting with a late-onset brain encephalopathy. She was treated with corticosteroids and discharged from hospital with good general condition. PMID:23956579

Anti-Ma2-associated encephalitis is a paraneoplastic disorder that predominantly affects the limbic system, diencephalon and brainstem, and is usually associated with tumors of the testis. We report a 35-year-old man with a right testicular mass who presented with multiple neurological complains, and clinical, serological and radiological features compatible with anti-Ma2-associated encephalitis. After three courses of carboplatin, etoposide and bleomycin for metastatic testicular germ-cell tumor, all elevated tumor markers normalized and the retroperitoneal metastases disappeared, but the neurological disorder deteriorated. To our knowledge, this is the first case in which orchiectomy followed by carboplatin, etoposide and bleomycin for a testicular tumor with anti-Ma2 encephalitis was performed.

Insulin Autoimmune Syndrome (IAS) is a rare condition characterized by the combination of recurrent severely spontaneous hypoglycemia without evidence of exogenous insulin administration, high concentration of total serum insulin, and the presence of a high titer of insulin autoantibody (IAA). But now we describe a case with IAS caused by gliclazide and hardly occuring hypoglycemia. A 70-year-old man with type 2 diabetes presented to our department with poor glycemic control without evidence of hypoglycemia, but the levels of serum insulin and IAA were very high. He had no exogenous insulin administration history. Switching antidiabetic therapy from gliclazide to acarbose and metformin, the patient's serum insulin level and IAA decreased gradually. Accordingly, the glycemic control improved and there was no episode of hypoglycemia. Hence, clinicians should pay more attention to type 2 diabetic patients treated with gliclazide and detect their serum insulin concentration and IAA to exclude or diagnose IAS and perform the best therapeutic regimen to these patients.

Guillain-Barre syndrome (GBS)-associated achalasia is a very rare disease of uncertain cause. We report the case of a patient diagnosed with GBS-associated type I achalasia who was successfully treated with peroral endoscopic myotomy (POEM). A 30-year-old man who was diagnosed with GBS 3 mo before was referred to our department with dysphagia and meal-related regurgitation. The results of esophagography, endoscopy, and high-resolution manometry (HRM) revealed type I achalasia. POEM that utilized a submucosal tunneling technique was performed to treat the GBS-associated type I achalasia. After POEM, smooth passage of a contrast agent into the stomach was shown in follow-up esophagography, and follow-up HRM revealed a decrease in the mean integrated relaxation pressure 22.9 mmHg to 9.6 mmHg. The patient remained without dysphagia for 7 mo, even though the patient’s neurological problems were not fully resolved. POEM may be a safe and effective treatment for GBS-associated type I achalasia. PMID:28223738

Anesthetic management of Costello syndrome: a case report.

Costello syndrome is a rare genetic disorder with an estimated 300 medical cases worldwide. Typical features that characterize this syndrome include short stature, macrocephaly, developmental delay, loose skin folds, distinctive coarse facial features, and multiorgan system anomalies. The following case report discusses the anesthetic management for a 3-year-old boy undergoing general anesthesia for a scheduled dental restoration, hydrocelectomy, inguinal hernia repair, and bilateral myringotomy with placement of pressure equalization tubes. A scarcity of literature for the anesthetic management of Costello syndrome (also known as faciocutaneoskeletal syndrome) exists. Utilizing an overview of the pertinent literature, clinical practice recommendations are suggested for the anesthetic implications of managing a pediatric patient with this rare syndrome.

The Gorlin-Goltz syndrome (GGS) (the nevoid basal cell carcinoma syndrome—NBCCS) is a rare autosomal dominant syndrome caused due to mutations in the PTCH (patched) gene found on chromosome arm 9q. The syndrome, characterized by increased predisposition to develop basal cell carcinoma and associated multiorgan anomalies, has a high level of penetrance and variable expressiveness. GGS is a multidisciplinary problem, early diagnosis of which allows introduction of secondary prophylaxis and following an appropriate treatment to delay the progress of the syndrome. The following report emphasizes the need for awareness of the diagnostic criteria of this syndrome in cases with no typical skin lesions. PMID:23082255

The short arm deletion syndrome of chromosome 4 (4p- syndrome).

PubMed

Zellweger, H; Bardach, J; Bordwell, J; Williams, K

1975-01-01

Partial deletion of the short arm of chromosome 4 (4p-) represents another (rare) cause of cleft lip and cleft palate. Further characteristic manifestations of the syndrome (also called Wolf or Wolf-Hirschhorn syndrome) are growth failure, microcephaly, prominent glabella, hypertelorism, beaked nose, poorly differentiated and low set ears, cardiac and renal malformation and hypospadias. Life expectancy is often shortened. The 4p- syndrome has many features in common with another deletion syndrome, the cri-du-chat syndrome, and also with the Smith-Lemli-Opitz syndrome. The latter is a hereditary condition with normal karyotype. The cri-du-chat syndrome is characterized by a peculiar high-pitched, mewing cry and can be differentiated from the Wolf syndrome by the different staining characteristics (banding) of chromosomes 4 and 5.

Mouse Models of Rare Craniofacial Disorders.

Achilleos, Annita; Trainor, Paul A

2015-01-01

A rare disease is defined as a condition that affects less than 1 in 2000 individuals. Currently more than 7000 rare diseases have been documented, and most are thought to be of genetic origin. Rare diseases primarily affect children, and congenital craniofacial syndromes and disorders constitute a significant proportion of rare diseases, with over 700 having been described to date. Modeling craniofacial disorders in animal models has been instrumental in uncovering the etiology and pathogenesis of numerous conditions and in some cases has even led to potential therapeutic avenues for their prevention. In this chapter, we focus primarily on two general classes of rare disorders, ribosomopathies and ciliopathies, and the surprising finding that the disruption of fundamental, global processes can result in tissue-specific craniofacial defects. In addition, we discuss recent advances in understanding the pathogenesis of an extremely rare and specific craniofacial condition known as syngnathia, based on the first mouse models for this condition. Approximately 1% of all babies are born with a minor or major developmental anomaly, and individuals suffering from rare diseases deserve the same quality of treatment and care and attention to their disease as other patients. © 2015 Elsevier Inc.

Cotard's syndrome is a rare syndrome, characterized by the presence of nihilistic delusions. The syndrome is typically related to depression and is mostly found in middle-aged or older people. A few cases have been reported in young people with 90% of these being females. We present a case of a young pregnant woman suffering from Cotard's syndrome. This is the first report of this syndrome in a pregnant woman. The case was diagnosed late, due to lack of awareness of psychiatric problems in primary care physicians resulting in undue suffering, loss of precious time and resources for the patient. Besides highlighting the rare combination of pregnancy and Cotard's syndrome this report delineates the difficulties faced by patients with such symptoms in a low resource setting. PMID:18271948

Pharyngeal-cervical-brachial (PCB) variant is a rare form of Guillan-Barre Syndrome (GBS). Antibodies against other membrane proteins like GM1b and GD1a have been found only in a small number of patients with Guillan Barre syndrome variant. Here, we report a 5.5 year-old boy diagnosed early with positive GD1a and GD1b gangliosides of Guillan-Barre syndrome pharyngeal cervical-Brachial variant, who improved and recovered fully in a short period. This is in contrast to those whose recovery period prolongs in spite of early diagnosis and appropriate treatment and/or those who experience incomplete recovery. In summary, diagnosis of PCB variant of GBS should be considered in infants with sudden onset bulbar symptoms and muscle weakness, and it should be kept in mind that early diagnosis and appropriate treatment can give successful outcomes.

Disorders of sex development (DSD) belong to uncommon pathologies; in addition, there are especially rare forms, such are ovotesticular disorders (OT), Turner syndrome and early malignisation of intraabdominal located gonads in the cases of androgen insensitivity syndrome. In this article we present four rare cases of DSD in female phenotype adolescents: two cases of ovotesticular DSD with 46,XX and 46,XY karyotypes; one familial case of androgen insensitivity syndrome (AIS) with early malignancy (19-year-old) of intra-abdominally-located testicle in older siblings, and a case of spontaneous menstruation in a patient with Turner syndrome and mosaic karyotype 45,X/47,XXX. Rare cases of DSD are connected with diagnostic and management difficulties and so description of each such case and collection of data in this field is very important from a scientific, as well as a practical, point of view. Determination of prognosis and adequate management of each individual patient are also essential. Study of this issue is especially sensitive in the case of adolescent patients in order to avoid physiological stress, to reduce health risks and to improve quality of life.

To describe a very common corneal pathology in a patient with Kindler syndrome. We report the case of a 21-year-old woman, who presented to the Ophthalmology Department as an emergency presentation because of ocular pain in the left eye that radiated to other areas of the face and neck. After an exhaustive clinical interview, it was determined that the patient had a rare disease (Kindler syndrome). Ophthalmologic examination revealed corneal erosion on the left eye. No other significant conditions were found. After the application of conventional treatment, the corneal integrity was completely restored. We describe a very rare syndrome. Although conventional treatment restored corneal integrity, it is important to remember that ocular signs and symptoms are often associated with systemic pathologies.

The DiGeorge Syndrome was first described in 1968 as a primary immunodeficiency resulting from the abnormal development of the third and fourth pharyngeal pouches during embryonic life. It is characterized by hypocalcemia due to hypoparathyroidism, heart defects, and thymic hypoplasia or aplasia. Its incidence is 1:3000 live births and, despite its high frequency, little is known about its natural history and progression. ←This is probably due to diagnostic difficulties and the great variety of names used to describe it, such as velocardiofacial, Shprintzen, DiGeorge, and CATCH 22 Syndromes, as well as conotruncal facial anomaly. All represent the same genetic condition, chromosome 22q11.2 deletion, which might have several clinical expressions. To describe clinical and laboratorial data and phenotypic characteristics of patients with DiGeorge Syndrome. Patients underwent standard clinical and epidemiological protocol and tests to detect heart diseases, facial abnormalities, dimorphisms, neurological or behavioral disorders, recurrent infections and other comorbidities. Of 14 patients (8m - 18y11m), only one did not have 22q11.2 deletion detected. The main findings were: conotruncal malformation (n = 12), facial abnormalities (n = 11), hypocalcemia (n = 5) and low lymphocyte count (n=2). The authors pointed out the necessity of DGS suspicion in all patient presenting with heart defects, facial abnormalities (associated or not with hypocalcemia), and immunological disorders because although frequency of DGS is high, few patients with a confirmed diagnosis are followed up.

Churg-Strauss syndrome (CSS) is a rare syndrome characterized by sinusitis, asthma and peripheral eosinophilia. This vasculitic syndrome affects medium and small-sized vessels, the lung being the most commonly affected organ, followed by the skin. The authors report a case of a 59-year-old male with a past history of asthma and allergic rhinitis. He presented necrohemorragic lesions in the distal phalanx of the 2nd, 3rd and 4th fingers of the left-hand and petechial lesions in the plant of both feet, accompanied by asthenia, anorexia and weight loss. The analytical study revealed leukocytosis with eosinophilia, elevated inflammatory parameters and p-ANCA positive antibodies. The diagnosis of CSS was established based on clinical and histopathological data. Cutaneous manifestations of hemorragic vasculitis are rare in CSS syndrome but can be the first manifestation of the disease. The recognition of this presentation is important for the early diagnosis and treatment of this syndrome. PMID:25386301

Background: Pharyngeal-cervical-brachial (PCB) variant is a rare form of Guillan-Barre Syndrome (GBS). Antibodies against other membrane proteins like GM1b and GD1a have been found only in a small number of patients with Guillan Barre syndrome variant. Case Report: Here, we report a 5.5 year-old boy diagnosed early with positive GD1a and GD1b gangliosides of Guillan-Barre syndrome pharyngeal cervical-Brachial variant, who improved and recovered fully in a short period. This is in contrast to those whose recovery period prolongs in spite of early diagnosis and appropriate treatment and/or those who experience incomplete recovery. Conclusion: In summary, diagnosis of PCB variant of GBS should be considered in infants with sudden onset bulbar symptoms and muscle weakness, and it should be kept in mind that early diagnosis and appropriate treatment can give successful outcomes.

Marfan syndrome (MFS) is an autosomal dominant disorder of connective tissue, while Duane retraction syndrome (DRS) is a congenital cranial dysinnervation disorder (CCDD) which can be transmitted as autosomal dominant disorder in 5–10% of patients. In this paper, we present an 8-year-old girl who presented with left eye DRS and bilateral subluxation of the lens associated with MFS in absence of familial involvement. To our knowledge this is the first case report of DRS with MFS. The occurrence of these syndromes together is very rare and appears to be coincidental. PMID:22606474

The Capgras syndrome in paranoid schizophrenia.

Silva, J A; Leong, G B

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.

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.

Schwanommas arising from cervical sympathetic chain are tumours that are rare in occurrence. These lesions are usually difficult to differentiate from a vagal schwanomma and a carotid body tumour during the initial workup. In this report, a rarely seen huge cervical sympathetic chain schwanomma case with partial Horner's syndrome is being presented in detail, which to our known knowledge, is one of the few cases reported in literature.

Among the etiologies of anemia in the newborn, those related to mitochondrial cytopathies are rare. Pearson syndrome is mostly diagnosed during infancy and characterized by refractory sideroblastic anemia with vacuolization of marrow progenitor cells and exocrine pancreatic dysfunction. We describe two diagnosed cases of Pearson syndrome in the early neonatal period caused by severe macrocytic aregenerative anemia. Bone marrow aspiration revealed sideroblastic anemia and vacuolization of erythroblastic precursors. The diagnosis was confirmed by genetic analysis revealing a deletion in the mitochondrial DNA. These two newborns received monthly transfusions. Five other newborns suffering from Pearson syndrome with various clinical symptoms were found in literature. Pearson syndrome, rarely diagnosed in newborns, should be suspected in the presence of macrocytic aregenerative anemia and requires a bone marrow aspirate followed by a genetic analysis from a blood sample.

Alström syndrome (AS) is a rare autosomal recessive disorder that shares clinical features with other ciliopathy-related diseases. Genetic mutation analysis is often required in making differential diagnosis but usually costly in time and effort using conventional Sanger sequencing. Herein we describe a Taiwanese patient presenting cone-rod dystrophy and early-onset obesity that progressed to diabetes mellitus with marked insulin resistance during adolescence. Whole exome sequencing of the patient's genomic DNA identified a novel frameshift mutation in exons 15 (c.10290_10291delTA, p.Lys3431Serfs * 10) and a rare mutation in 16 (c.10823_10824delAG, p.Arg3609Alafs * 6) of ALMS1 gene. The compound heterozygous mutations were predicted to render truncated proteins. This report highlighted the clinical utility of exome sequencing and extended the knowledge of mutation spectrum in AS patients.

Zika virus (ZIKV) is an emerging virus involved in recent outbreaks in Brazil. The association between the virus and Guillain-Barré syndrome (GBS) or congenital disorders has raised a worldwide concern. In this work, we investigated a rare Zika case, which was associated with GBS and spontaneous retained abortion. Using specific anti-ZIKV staining, the virus was identified in placenta (mainly in Hofbauer cells) and in several fetal tissues, such as brain, lungs, kidneys, skin and liver. Histological analyses of the placenta and fetal organs revealed different types of tissue abnormalities, which included inflammation, hemorrhage, edema and necrosis in placenta, as well as tissue disorganization in the fetus. Increased cellularity (Hofbauer cells and TCD8 + lymphocytes), expression of local pro-inflammatory cytokines such as IFN-γ and TNF-α, and other markers, such as RANTES/CCL5 and VEGFR2, supported placental inflammation and dysfunction. The commitment of the maternal-fetal link in association with fetal damage gave rise to a discussion regarding the influence of the maternal immunity toward the fetal development. Findings presented in this work may help understanding the ZIKV immunopathogenesis under the rare contexts of spontaneous abortions in association with GBS.

Oral and Craniofacial Anomalies of Bardet-Biedl Syndrome: Dental Management in the Context of a Rare Disease.

Standardized guidelines for the oral health management of patients with rare diseases exhibiting morphologic anomalies are currently lacking. This review considers Bardet-Biedl syndrome (BBS), a monogenic autosomal recessive nonmotile ciliopathy, as an archetypal condition. Dental anomalies are present in a majority of individuals affected by BBS due to abnormal embryonic orofacial and tooth development. Genetically encoded intrinsic oral structural anomalies and heterogeneous BBS clinical phenotypes and consequent oral comorbidities confound oral health management. Since the comorbid spectrum of BBS phenotypes spans diabetes, renal disease, obesity, sleep apnea, cardiovascular disease, and cognitive disorders, a broad spectrum of collateral oral disease may be encountered. The genetic impact of BBS on the anatomic development of oral components and oral pathology encountered in the context of various BBS phenotypes and their associated comorbidities are reviewed herein. Challenges encountered in managing patients with BBS are highlighted, emphasizing the spectrum of oral pathology associated with heterogeneous clinical phenotypic expression. Guidelines for provision of care across the spectrum of BBS clinical phenotypes are considered. Establishment of integrated medical-dental delivery models of oral care in the context of rare diseases is emphasized, including involvement of caregivers in the context of managing these patients with special needs.

Nevoid Basal Cell Carcinoma Syndrome (Gorlin Syndrome).

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

2016-06-01

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

A woman developed brain stem encephalopathy in association with serum anti-Ma2 antibodies and left upper lobe lung mass. T2 weighted MRI of the brain showed abnormalities involving the pons, left middle and superior cerebellar peduncles, and bilateral basal ganglia. Immunohistochemical analysis for serum antineuronal antibodies was confounded by the presence of a non-neuronal specific antinuclear antibody. Immunoblot studies showed the presence of anti-Ma2 antibodies. A premortem tissue diagnosis of the lung mass could not be established despite two CT guided needle biopsies, and the patient died as a result of rapid neurological deterioration. The necropsy showed that the lung lesion was an adenocarcinoma which expressed Ma2 immunoreactive protein. Neuropathological findings included prominent perivascular inflammatory infiltrates, glial nodules, and neuronophagia involving the brain stem, basal ganglia, hippocampus and the dentate nucleus of the cerebellum. Ma2 is an autoantigen previously identified in patients with germ cell tumours of the testis and paraneoplastic brain stem and limbic encephalitis. Our patient's clinical and immunopathological findings indicate that this disorder can affect women with lung adenocarcinoma, and that the encephalitic changes predominate in those regions of the brain known to express high concentrations of Ma proteins.
