A 34-year-old alcoholic man had neurological and cardiac symptoms. The patient was admitted to the hospital for acute painful sensory disturbances and severe weakness of the feet. Neurological and electrophysiological investigation revealed axonal sensorimotor polyneuropathy that was most prominent in the legs. Cardiac assessment showed signs and symptoms of heart failure due to a high-output state. Blood analysis showed a low thiamine concentration of 58 nmol/l (lower reference limit: 80). Therefore, a diagnosis of combined wet beriberi with cardiomyopathy and dry beriberi with axonal polyneuropathy was made. The treatment of beriberi is simple and effective and consists of thiamine supplementation in conjunction with diuretic treatment. With this approach, the patient recovered fully. Patients with beriberi have a good prognosis, particularly when the diagnosis is made at an early stage.

In order to downstage locally advanced breast cancer, neoadjuvant chemotherapy consisting of intravenous vinorelbine 25 mg/m plus epirubicin 75 mg/m given on day 1 and oral vinorelbine 60 mg/m on day 8 was administered every 3 weeks for four courses. On day 2, all patients received a single subcutaneous injection of pegfilgrastim (6 mg). From March 2004 to June 2005, 22 patients were enrolled. Patients characteristics were: median age, 53 years (range: 39-70 years); postmenopausal, 7/22; clinical TNM stage, T2 (n=14), T3 (n=8), N0 (n=17) and N1 (n=5). The median number of courses was four (range: two to six courses) with full dose intensity. National Cancer Institute grade 3 haematological toxicities observed were neutropenia in 9% of patients, anaemia in 13% of patients and thrombocytopenia in 9% of patients; no toxicity grade 4 occurred. Two patients (9%) registered grade 2 polyneuropathy; no cardiac failure was observed. Conservative surgery was performed in 14 patients (63%). All patients were evaluable for response: complete pathological response was documented in three patients (13.6%); three patients (13.6%) obtained more than 75% of tumour size reduction; 11 other patients (50%) had 50% of tumour size reduction; stable disease was observed in five patients (22.7%). The present findings indicate that vinorelbine in combination with epirubicin is an effective and safe treatment in locally advanced breast cancer: this regimen obtained more than 50% of tumour size reduction in 77% of patients; the use of pegfilgrastim allowed full dose intensity. Oral vinorelbine on day 8 offers greater convenience to the patient by reducing the need for intravenous injection and the time spent in hospital.

In single cases mitochondrial disorders may manifest as pancreatitis, but recurrent, chronic pancreatitis with exacerbations of at least 15 times without morphological alterations of the pancreas but concomitant diabetes mellitus has not been reported. In a 57-year-old Caucasian male mitochondrial disorder was diagnosed at the age of 49 years upon epilepsy with generalized and focal seizures, cognitive decline, migraine, mitochondrial myopathy, polyneuropathy, diabetes mellitus, hypokalie-mia, hyperlipidemia, atrial fibrillation, heart failure, sicca syndrome, recurrent pancreatitis, chronic diarrhea, polydipsia, hyperhidrosis, steatosis hepatis, anemia, thrombopenia, an abnormal lactate stress test, and a muscle biopsy showing ragged-red muscle fibers, single completely COX-negative fibers, target fibers, increased number of sarcoplasmatic lipid droplets, but normal mitochondrial morphology on electron microscopy. Between the age of 33 years and the age of 44 years, at least 15 episodes of pancreatitis, manifesting as severe abdominal pain, and elevated exocrine pancreatic enzymes, but without morphological alterations of the pancreas, responding well to H2-blockers and food restriction had occurred. Recurrent pancreatitis without morphological alterations of the pancreas may be a feature of multisystem mitochondrial disorder resulting in diabetes mellitus. Physicians should familiarize with pancreatitis as a manifestation of a mitochondrial disorder and mitochondrial disorder should be excluded in patients with pancreatitis.

In a 94-year-old male with a history of atrial fibrillation, aortic stenosis, heart failure, apical thrombus, arterial hypertension, aneurysm of the abdominal aorta, and a urinary bladder carcinoma, cardiologic investigations revealed pulmonary rales, enlarged heart, absolute arrhythmia, and positive troponin-, myocardial thickening, enlarged cardiac cavities, hypocontractility, aortic stenosis, slight aortic insufficiency, severe mitral insufficiency, and surprisingly left ventricular hypertrabeculation. Upon neurological investigations, a polyneuropathy was suspected but a myopathy not completely excluded. The presented case shows that LVHT occurs also in nonagenarians and is associated with neuromuscular disease and positive troponin-T, in the absence of ischemic heart disease or severe renal failure. The cause of troponin-T-positivity remains multi-factorial.

Amiodarone chlorhydrate is a diiodated benzofuran derivative, and it is used to treat cardiac rhythm abnormalities. Hepatotoxicity is a relatively uncommon side effect of amiodarone, and symptomatic hepatic dysfunction occurs in fewer than 1% of the patients taking amiodarone. Cirrhosis is a rare complication that's been confirmed in 12 cases. Peripheral neuropathy occurs in 10% of patients taking aminodarone. We report here on an unusual case of amiodarone-induced hepatotoxicity and peripheral neurotoxicity. A 75 year old man with normal liver function was given amiodarone for treating his atrial fibrillation and heart failure. He developed nausea, vomiting, muscle weakness and wasting after 17.8 months therapy with amiodarone (400 mg orally once per day). Liver biopsy showed the presence of foam cells in the hepatic sinusoids and Mallory bodies in the periportal hepatocytes on light microscopy. Sural nerve biopsy showed demyelination, and nerve conduction studies showed mixed sensorimotor polyneuropathy. These observations show the necessity of monitoring the hepatic function and conducting neurologic examination of the patients treated with amiodarone.

A 63-year-old Caucasian male, diagnosed with dilated cardiomyopathy in 1993, remained clinically stable for several years. In 2003, a marked increase of N-terminal pro-natriuretic peptide serum level (611 ng/ml to 4926 ng/ml) was observed; left ventricular (LV) septum thickness was 10 mm. In addition, sensorimotor polyneuropathy and autonomic dysfunction occurred. Further progression of heart failure occurred despite unchanged systolic LV function. Endomyocardial biopsy in 2006 revealed transthyretin amyloidosis by Congo red and immunohistochemical staining, as well as Val94Ala substitution by transthyretin gene analysis. Cardiac amyloid deposition was quantified by technetium-99m-3,3-diphosphono-1,2-propanodicarboxylic acid (99mTc-DPD) scintigraphy. Mutational search of the relatives (n = 1) was unremarkable. The transthyretin Val94Ala mutation is characterized by sensorimotor polyneuropathy, autonomic dysfunction, and gastrointestinal and cardiac involvement with amyloid. This mutation is an addition to the growing spectrum of transthyretin mutations with late onset of clinical symptoms, but noteworthy because of progressive, finally disabling disease course. Final clinical assessment of severity of cardiac involvement in the present patient is rendered complex by possible concomitant or preceding idiopathic dilated cardiomyopathy.

Liver cirrhosis and portal hypertension are frequently associated with signs of circulatory dysfunction and peripheral polyneuropathy, which includes defects of the autonomic nervous system. Autonomic dysfunction, which is seen in both alcoholic and non-alcoholic liver cirrhosis and increases with severity and duration of the liver disease, is associated with a significant increase in mortality. The lack of total resolution after liver transplantation indicates that the autonomic neuropathy is not exclusively functional. This article highlights some aspects of the autonomic dysfunction in chronic liver disease. A description is given of its aetiology and the typical circulatory dysfunction with characteristic hyperdynamic and hyporeactive circulation and heart failure, and the most important tests of the autonomic nervous system.

Thiamine deficiency may present four classic clinical forms: peripheral polyneuropathy, anorexia and muscular weakness (dry beriberi); high output heart failure with signs of congestion (wet beriberi); beriberi associated with shock (Shoshin beriberi) and Wernicke's encephalopathy. In this report we describe a picture that is suggestive of severe pulmonary hypertension and cor pulmonale, with jugular stasis, congestive hepatitis and generalized edema that reversed completely after the administration of thiamine.

The purpose of this study was to evaluate the clinical and pathological features in patients with progressive-type familial amyloidotic polyneuropathy (FAP) using autopsy and biopsy specimens. A proband is a 33-year-old man with FAP type I who developed motor, sensory and autonomic impairments with neuropathy, heart failure, and anorexia. Genetic findings of transthyretin (TTR) revealed G to A transition in codon 54 causing a rare mutation of TTR Lys54. He died of pneumonia and severe cardiac failure 4 years after onset. Autopsy showed heavy amyloid deposition in the heart, peripheral nerves, thyroid, skin, fat tissue, prostate and testis, moderate in the sympathetic nerve trunk, vagal nerve, celiac plexus, pelvic plexus, bladder, gastrointestinal tract, tongue, pancreas, lung, pituitary, blood vessel, gall bladder, adrenals and muscles, and free in the central nervous system, liver, kidney and spleen. Sural nerve biopsy in a sibling confirmed TTR amyloidosis immunohistochemically. Electronmicroscopic findings of amyloid fibrils were similar to that of FAP Met30. Immunoelectronmicroscopic findings indicated the relationship between amyloid fibrils or non-fibrillar structure and collagen fibers. The distribution of amyloid deposition, heavy in the heart and lacking in the kidney, is a characteristic feature and reflected severity of FAP with TTR Lys54.

Beriberi is an uncommon disorder related to thiamine deficiency. It is mainly found in underdeveloped countries among populations with poorly diversified diet, consisting largely of milled white cereals, a poor source of thiamine. In industrialized countries, thiamine deficiency with cardiac failure is more frequently found than the dry beriberi in high risk groups like chronic alcoholics. Nevertheless our attention was drawn to an outbreak of 70 cases of dry beriberi which occurred from 1997 to 2005 in the French territories of Reunion and Mayotte islands. It was characterized by an acute or sub-acute sensorimotor polyneuropathy with axonal lesions, affecting the lower limbs and occasionally the upper limbs, sometimes associated with cardiac beriberi. It affected young, non alcoholic individuals from the Mahoran and Comorian community who were in apparent good health when the illness occurred. Our study highlighted the feeding habits which are partly responsible for the development of the disease due to a chronic lack of thiamine and which probably contributed together with multiple cofactors to trigger off the illness. But many elements and mainly biological ones, also lead us to think that there is a genetic predisposition to develop this neuropathy.
