Kyung Hee Kim, Ki Young Oh
Phlebotomy is the removal of blood from the body, and therapeutic phlebotomy is the preferred treatment for blood disorders in which the removal of red blood cells or serum iron is the most efficient method for managing the symptoms and complications. Therapeutic phlebotomy is currently indicated for the treatment of hemochromatosis, polycythemia vera, porphyria cutanea tarda, sickle cell disease, and nonalcoholic fatty liver disease with hyperferritinemia. This review discusses therapeutic phlebotomy and the related disorders and also offers guidelines for establishing a therapeutic phlebotomy program...

BACKGROUND: The Royal College of Pathologists of Australasia (RCPA) Porphyrin Quality Assurance Program assesses the measurement of urine, faecal, plasma and whole blood porphyrins and their components plus urinary porphobilinogen and delta aminolaevulinic acid and has laboratories enrolled from around the world. It was observed that there was a wide scatter in results submitted to some subsections of the program. METHODS: A detailed questionnaire covering the analytical techniques used in the diagnosis of porphyria was sent to all laboratories enrolled in the RCPA Porphyrin Quality Assurance Program...

Acute porphyrias are a heterogeneous group of metabolic disorders resulting from a variable catalytic defect of four enzymes out of the eight involved in the haem biosynthesis pathway; they are rare and mostly inherited diseases, but in some circumstances, the metabolic disturbance may be acquired. Many different environmental factors or pathological conditions (such as drugs, calorie restriction, hormones, infections, or alcohol abuse) often play a key role in triggering the clinical exacerbation (acute porphyric attack) of these diseases that may often mimic many other more common acute medical and neuropsychiatric conditions and whose delayed diagnosis and treatment may be fatal...

The British and Irish Porphyria Network guidelines describe best practice in the clinical assessment, investigation and management of acute porphyria attacks and their complications, including severe attacks with neuropathy. Acute attacks of porphyria may occur in acute intermittent porphyria (AIP), variegate porphyria (VP) and hereditary coproporphyria (HCP). Aminolaevulinic acid dehydratase deficiency porphyria (ADP) is a very rare autosomal recessive porphyria; only six cases substantiated by mutation analysis have yet been described in the literature...

A provoked seizure may be due to structural damage (resulting from traumatic brain injury, brain tumor, stroke, tuberculosis, or neurocysticercosis) or due to metabolic abnormalities (such as alcohol withdrawal and renal or hepatic failure). This article is a part of the Guidelines for Epilepsy in India. This article reviews the problem of provoked seizure and its management and also provides recommendations based on currently available information. Seizure provoked by metabolic disturbances requires correction of the triggering factors...

BACKGROUND: A high number of patients with epilepsy have comorbidities. The type of comorbidity is an important factor in deciding on the most suitable treatment, including that for acute epileptic seizures and chronic antiepileptic treatment. Evidence-based criteria should guide the selection of the appropriate antiepileptic drugs given specific comorbidities. METHODS: We performed a comprehensive search of the scientific literature on epilepsy treatment in patients with the following comorbidities: heart disease, lung disease, liver disease, kidney disease, porphyria, organ transplantation, thyroid disease, metabolic disorder, infection, mental disability, psychiatric disorder, cognitive impairment, stroke, and brain tumour...

OBJECTIVE: Acute intermittent porphyria (AIP) is caused by a deficiency of hydroxymethylbilane synthase. Clinical manifestations are abdominal pain and neurovisceral symptoms, accompanied by overproduction of heme-precursors in the liver, which frequently remains long-lasting in AIP patients. We tested the hypothesis that this condition may be associated with alterations of hepatic proteins known to be either increased or decreased in serum according to diverse pathological conditions including malnutrition, inflammation or liver disease...

The treatment of acute myocardial infarction as described in guidelines, generaly meets with few contra-indications. In our clinical practice, we have met an exceptional one: acute intermittent porphyria. This disease is characterized by acute abdominal pain, neurologic disturbances and cardiac arrhythmias related to different stimuli such as some drugs. Among these drugs, several molecules are usually used for treatment of acute coronary syndromes. Knowledge of these the therapies is crucial to avoid some dangerous consequences...

REVIEW

Hyoscine-N-butylbromide (Buscopan, Boehringer Ingelheim) is a widely used antispasmodic in radiological practice. There seems to be no consensus as to best practice within radiology regarding the precautions that need to be taken when prescribing Buscopan. We have performed a thorough review of the available literature and make the following recommendations to those administering Buscopan: (1) enquire whether there is an allergic history; (2) ensure patient literature warns that "in the rare event that following the examination you develop painful, blurred vision in one or both eyes, you must attend hospital immediately for assessment"; (3) warn patients to expect blurred vision and not to drive until this has worn off; (4) remind clinicians that special consideration needs to be given as to the method of investigating patients with cardiac instability, such as those recently admitted with acute coronary syndrome, recurrent cardiac pain at rest, uncontrolled left ventricular failure and recent ventricular arrhythmias...

BACKGROUND: Acute Intermittent Porphyria (AIP) is a rare autosomal dominant metabolic disorder resulting from partial deficiency of porphobobilinogen deaminase, the third enzyme of the haem synthetic pathway. Patients with AIP may be vulnerable to acute neurovisceral attacks if exposed to certain drugs, including some drugs used in dental practice. CASE REPORTS: This article outlines the dental management of 5 children with a diagnosis of latent AIP or a family history of AIP...

Inborn errors of metabolism (IEMs) may present in adolescence or adulthood as a psychiatric disorder. In some instances, an IEM is suspected because of informative family history or because psychiatric symptoms form part of a more diffuse clinical picture with systemic, cognitive or motor neurological signs. However, in some cases, psychiatric signs may be apparently isolated. We propose a schematic classification of IEMs into three groups according to the type of psychiatric signs at onset. Group 1 represents emergencies, in which disorders can present with acute and recurrent attacks of confusion, sometimes misdiagnosed as acute psychosis...

Porphyrias are uncommon inherited diseases of haem biosynthesis for which the diagnosis and treatment varies in individual countries. Despite the existence of guidelines recommended by porphyria experts concerning the diagnosis and management of the acute porphyrias, and of specialist centres in most European countries, many clinicians still do not apply these guidelines. The European Porphyia Initiative (EPI) network was formed in 2001 in order to compare experience among countries to attempt to develop a common approach to the management of the porphyrias, particularly concerning recommendation of safe and unsafe drugs, and to facilitate international collaborative clinical and biological research...

Hereditary photodermatoses are characterized by an increased photosensitivity caused by an inherited single gene defect. With few exceptions, they manifest in early childhood, reveal heterogeneous clinical symptoms, and are difficult to treat. Although these diseases are rare, it is very important to make an accurate diagnosis on the basis of clinical symptoms, specific diagnostic tests, and direct DNA analysis. We review the spectrum of inherited photodermatoses, including porphyria cutanea tarda, erythropoietic protoporphyria, actinic prurigo, Kindler syndrome, and disorders associated with a defect in DNA repair, including xeroderma pigmentosum, trichothiodystrophy, Cockayne syndrome, and Bloom syndrome...

REVIEW
Alfred O Mueck
Using hormone replacement therapy (HRT), absolute and relative contradictions have to be considered, which are primarily classified according to a "worst case" scenario on the assumption of group effects, in order to satisfy forensic demands. However, in patients with severe complaints it make sense to apply HRT even at increased risk. To minimize the risk, a differentiated choice of the preparation especially in terms of progestin component and application mode is feasible apart from a general dose reduction...

Hepatitis C Virus is associated with a wide series of extrahepatic manifestations. Based on available data the link between the virus and some of these extrahepatic diseases is only suggested and needs further confirmation. Hepatitis C Virus-related lymphoproliferative disorders, whose prototype is mixed cryoglobulinaemia, represent the most closely related extrahepatic manifestations of Hepatitis C Virus. Other Hepatitis C Virus-associated disorders include nephropathies, thyreopathies, sicca syndrome, idiopathic pulmonary fibrosis, porphyria cutanea tarda, lichen planus, diabetes, chronic polyarthritis, cardiopathy and atherosclerosis...

The porphyrias are a heterogeneous group of predominantly hereditary metabolic diseases resulting from a dysfunction of heme biosynthesis. Most of the porphyrias can manifest with a broad range of cutaneous symptoms on the sun-exposed areas of the body, whereas other variants reveal life-threatening acute neurological attacks. Further, mixed types of porphyrias exist. Besides the skin, other organs can be affected, such as the liver and the central nervous system. Therefore, interdisciplinary supervision of these patients is mandatory...
