The anti-Hu antibody (HuAb) is directed against RNA-associated neuronal proteins and is known to cause paraneoplastic encephalomyelitis/sensory neuronopathy syndrome mostly when associated with small cell lung cancer (SCLC). Paraneoplastic encephalomyelitis/sensory neuronopathy syndrome with concurrent autonomic neuropathy has been reported to occur in paraneoplastic syndromes, although its occurrence concomitant with acute pandysautonomia is less frequent. The authors describe the clinical, neuropathologic, and serologic features of two cases with an anti-Hu-related paraneoplastic syndrome presenting with progressive autonomic neuropathy. Both patients showed features of dysautonomia, including postural dizziness, abdominal pain, and diarrhea, and symptoms of sensory neuropathy. Investigations disclosed severe sensory and autonomic neuropathy and positive HuAb titers. The disease of patient 1 had a very rapid progression, and the patient died of cardiac arrest within 2 months of the onset of symptoms.
Patients usually go to their doctors with neurological complaints and later find they have cancer, a known paraneoplastic syndrome, or neurological problems that suggest a paraneoplastic syndrome. Paraneoplastic syndromes are rare conditions in which the immune system is involved in causing brain damage and fighting cancer.. Such patients with paraneoplastic neurologic degenerations(PNDs) may have autoantibodies, an antibody or protein the immune system creates that is directed against his or her own proteins. This study aims to better understand PNDS by:. ...
... are a group of rare degenerative disorders that are triggered by a persons immune system response to a neoplasm, or cancerous tumour. Neurologic paraneoplastic syndromes are believed to occur when cancer-fighting antibodies or white blood cells known as T cells mistakenly attack normal cells in the nervous system. These disorders typically affect middle-aged to older persons and are most common in persons with lung, ovarian, lymphatic, or breast cancer. Neurologic symptoms generally develop over a period of days to weeks and usually occur prior to tumour detection, which can complicate diagnosis. These symptoms may include difficulty in walking and/or swallowing, loss of muscle tone, loss of fine motor coordination, slurred speech, memory loss, vision problems, sleep disturbances, dementia, seizures, sensory loss in the limbs, and vertigo. Neurologic paraneoplastic syndromes include Lambert-Eaton myasthenic syndrome, stiff-person syndrome, encephalomyelitis ...
A paraneoplastic syndrome is a syndrome (a set of signs and symptoms) that is the consequence of cancer in the body, but unlike mass effect, is not due to the local presence of cancer cells. In contrast, these phenomena are mediated by humoral factors (such as hormones or cytokines) secreted by tumor cells or by an immune response against the tumor. Paraneoplastic syndromes are typical among middle-aged to older patients, and they most commonly present with cancers of the lung, breast, ovaries, or lymphatic system (a lymphoma). Sometimes, the symptoms of paraneoplastic syndromes show before the diagnosis of a malignancy, which has been hypothesized to relate to the disease pathogenesis. In this paradigm, tumor cells express tissue-restricted antigens (e.g., neuronal proteins), triggering an anti-tumor immune response which may be partially or, rarely, completely effective in suppressing tumor growth and symptoms. Patients then come to clinical attention when this tumor immune response breaks ...

Treating a patient with paraneoplastic syndrome goes hand-in-hand with treating the cancer itself, and may include slowing the immune system response thats responsible for the adverse neurological symptoms. A treatment plan must be developed thats appropriate for the particular kind of paraneoplastic syndrome a person has. In combination with chemotherapy drugs to destroy any existing cancer, a physician can prescribe a number of different drugs to limit the tissue damage caused by an overactive immune system. Corticosteroids like prednisone help to lessen inflammation in the body. Unfortunately, some of the potential long-term complications of steroids are diabetes mellitus, osteoporosis, hypertension, and high cholesterol levels, among others. Immunosuppressant drugs like azathioprine and cyclophosphamide help slow down the bodys release of cancer-battling white blood cells, but a negative side effect of these medications is an increased vulnerability to bacterial infections. Based on the ...

Paraneoplastic pemphigus. Close-up of paraneoplastic pemphigus (PNP) lesions on the shoulder and chest of a 60-year-old male patient with non-Hodgkins lymphoma, a form of blood cancer. PNP is an autoimmune disease resulting from an underlying tumour. It is thought that antigens associated with the tumour trigger an immune response that results in blistering of the skin near the tumour. Non-Hodgkins lymphoma is one of the two malignant tumours most commonly associated with PNP. Prognosis is poor. - Stock Image C029/2399
Paraneoplastic pemphigus is an autoimmune acantholytic mucocutaneous disorder that rarely accompanies an overt or occult neoplasm. Typical features include painful mucosal erosive lesions and pruritic papulosquamous eruptions that often progress to blisters. The antibody is a unique immunoglobulin G that recognises epidermal proteins. We discuss the case of a 23-year-old woman who presented with anaplastic large cell lymphoma complicated by paraneoplastic pemphigus, rapidly resulting in fatal multiorgan failure.. A 23-year-old woman presented with 1 week of fever and a disseminated erythrodermic rash with desquamation of the hands and feet, and erosions in the mouth. A local doctor started treatment with ciprofloxacin and prednisolone ...
Introduction: Gallbladder carcinoma has been associated with various paraneoplastic syndromes. These may be the presenting manifestations that lead the clinician to a diagnosis. Case Report: We report a case of small cell gallbladder carcinoma complicated by paraneoplastic hyponatremia. The hyponatremia was further exacerbated by platinum-based chemotherapy. Discussion: There have previously been no reports of paraneoplastic hyponatremia in gallbladder carcinoma. We discuss the management of this problem and also provide a short literature review on the other paraneoplastic syndromes associated with gallbladder carcinoma. Conclusion: Symptoms and signs of gallbladder cancer may be insidious. Thorough workup is needed if the patient presents with symptoms and signs of a paraneoplastic syndrome. © 2010 Springer Science+Business Media, LLC ...
Paraneoplastic syndromes exist for a number of malignancies and their presentations are diverse. Some of them are self-limited, while others can be life-threatening but regardless of the outcome, understanding the presentation is vital to picking up on the diagnosis for further treatment. The case that is presented here is a rare paraneoplastic skin process called Bazex syndrome that was associated with pancreatic adenocarcinoma.
Paraneoplastic syndrome is often associated with small cell lung cancer that has the potential to cause disability to a multitude of organ function.

Paraneoplastic pemphigus is an autoimmune disorder stemming from an underlying tumor. It is hypothesized that antigens associated with the tumor trigger an immune response resulting in blistering of the skin and mucous membranes. While patients with malignant and benign tumors are both at risk, malignancy is associated with high mortality rates (near 90%). Current treatment focuses on general wound healing and administering corticosteroids, which has not demonstrated a high success rate. Recent research developments aim to treat the underlying tumor in order to alleviate the symptoms of PNP. While the presence of lesions is the denominator among patients with PNP, the characteristics of the lesions differ. The five clinical presentations of lesions associated with PNP include: "Pemphigus-like": Flaccid blister (discrete), crusts over the raw exuding skin lesions "Pemphigoid-like": Tense blister(s) on brick red erythema "Erythema multiforme-like": Severe polymorphic skin and/or mucous membrane ...
A paraneoplastic syndrome can often present as the first manifestation of an underlying malignancy. We report a patient who presented with cholestatic jaundice as a paraneoplastic syndrome from his newly diagnosed metastatic prostate cancer. He received initial treatment with androgen deprivation therapy followed by six cycles of docetaxel resulting in resolution of his cholestatic process, normalization of liver enzyme levels, and excellent biochemical and radiographic response. To the best of our knowledge, this is the first reported case of metastatic prostate cancer with cholestatic jaundice as a paraneoplastic phenomenon to be safely treated with androgen deprivation therapy and upfront docetaxel, reflecting the latest shift in the treatment of metastatic prostate cancer.

Many people believe that neurologists are particularly attracted to detail. I prefer to think of the issue as one of precision rather than pointless obsessiveness. Some years ago, I was asked to discuss a case for the New England Journal of Medicines series of CPCs called the Cabot Cases.. In preparing the case for publication, I found myself in an argument with the editor about the placement of an apostrophe. There were two diagnoses in this case: aphasia from a cardiac source embolism to the left cerebral hemisphere and hypercoagulability as a paraneoplastic syndrome. In my view, aphasia is a Trousseau syndrome (i.e., the word "aphasia" was suggested by Trousseau), whereas hypercoagulability as a paraneoplastic syndrome was Trousseaus syndrome, because Trousseau both described and suffered from the disease. I am very much opposed to the trend to remove eponyms from the names of diseases and syndromes as to do so strips medicine of some of its most illustrious history. But, only a handful of ...
A 74-year-old Caucasian woman presented to the Emergency Department (ED) at our hospital with acute onset of thoracic back pain. Her medical history included hypertension, hypothyroidism, a right hip replacement, and diffuse large cell lymphoma in 1985, which was treated successfully with chemotherapy and radiation. She was a previous smoker who had quit approximately five years earlier. Upon review of her systems, she complained only of some diarrhea that she had experienced intermittently for one year. Her medications included atenolol, hydrochlorothiazide, and levothyroxine. Her vital signs and physical examination in the ED were remarkable only for thoracic spine tenderness. X-rays revealed a compression fracture of her T9 vertebra (age indeterminate) and a new left hilar mass. A renal panel revealed the following abnormalities: potassium 2.7 mEq/l (lower limit of normal (LLN), 3.5 mEq/l), chloride 74 mEq/l (LLN, 101 mEq/l), bicarbonate 47 mM/l (upper limit of normal (ULN), 36 mM/l), glucose ...

He was in the Army from 1968 to 1970. He was stationed in Vietnam for 15 months and reports
Autoimmune paraneoplastic autonomic neuropathy is a rare paraneoplastic syndrome (PNS), which manifests as disturbance in sympathetic and/or parasympathetic nervous system function. More often, autonomic problems in cancer patients are attributable to prolonged bed rest, neurotoxic chemotherapy, high-dose analgesics, and malnutrition.

A diverse array of molecular mechanisms has been suggested to cause ectopic hormone production. In rare instances, genetic rearrangements explain aberrant hormone expression. For example, translocation of the parathyroid hormone (PTH) gene can result in high levels of PTH expression in tissues other than the parathyroid gland because the genetic rearrangement brings the PTH gene under the control of atypical regulatory elements. A related phenomenon is well documented in many forms of leukemia and lymphoma, in which somatic genetic rearrangements confer a growth advantage and alter cellular differentiation and function (Chap. 16). Although genetic rearrangements cause selected cases of ectopic hormone production, this mechanism is rare, as many tumors are associated with excessive production of numerous peptides. Cellular dedifferentiation probably underlies most cases of ectopic hormone production. Many cancers are poorly differentiated, and certain tumor products, such as human chorionic ...

WHAT ARE BRAIN INFECTIONS? Brain infections are caused by viruses, bacteria, fungi, or parasites. These infectious agents cause inflammation of the affected brain area. Other parts of the Central Nervous System, such as the Spinal Cord, are often included in the infection. Depending on the location of the infection, different names are given to the diseases. BRAIN INFECTIONS Meningitis is the inflammation of the meninges, or the protective membranes covering the brain and spinal cord.

In 2013 more than 150,000 Americans died from all types of lung cancer. Small cell lung cancer (SCLC) represents about 13% of all lung cancers and is notoriously associated with paraneoplastic syndromes (PNS). Here we present an interesting case of psychosis associated with one such PNS-- ectopic Cushing syndrome of SCLC. A 56 year old African-American male with no prior psychiatric history who was diagnosed with SCLC two months prior, presented to the ER for treatment of a right arm laceration he sustained while fighting off attackers, with high concern these individuals may have been part of hallucinatory experiences and well-systematized persecutory delusions regarding his wife ...

The risk for VTE increases in patients with cancer. In the current study, the median time interval from cancer diagnosis to PE diagnosis was 5.5 months, and 70% of the patients were diagnosed with PE within 1 year after the cancer diagnosis. Almost 90% of the patients had metastatic disease. In a previous cohort study including 235,149 patients with cancer [5], the incidence of a thromboembolic event among patients with either metastatic- or regional-stage disease was highest in the first few months after diagnosis, and the incidence decreased over time for most cancers. In a case-control study of patients with acute VTE [2], the incidence of VTE was highest in the first 6 months after the cancer diagnosis. In another lung cancer cohort study [6], the VTE incidence rate was highest in the first 6 months after the cancer diagnosis, averaging 7.2 VTE events/100 patient-years. Patients with distant metastasis are at an increased risk for VTE [2,5-9], and the current study findings are consistent ...
