Treatment Most patients in developed countries attend specialized haemophilia centres where there is a multidisciplinary team dedicated to their care. Guidelines exist for the plasma level to be achieved for different types of haemorrhage. Local supportive measures used in treating haemarthroses and haematomas include resting the affected part, application of ice and the prevention of further trauma. At the earliest suggestion of bleeding, the haemophilic child may be treated at home. This advance has reduced the occurrence of crippling haemarthroses and the need for inpatient care. Severely affected patients are now reaching adult life with little or no arthritis. This may require the placement of a vascular access device such as Port-a-Cath if venous access is difficult. A controlled trial has proven that regular prophylaxis is far superior to on-demand treatment as judged by progression of joint damage, which was virtually absent in children on prophylaxis but always seen in boys treated on-demand. Haemophiliac children and their parents often require extensive help with social and psychological matters. Various viral vectors (retroviral, adeno-associated) as well as non-viral vectors are being explored. Immunosuppression and immune tolerance regimens have been used in an attempt to eradicate the antibody with success (at great cost) in about two-thirds of cases. Indeed, the two disorders can only be distinguished by specific coagulation factor assays. Also the distribution and kinetics of clearance differ from the natural product, but it is certainly safe and effective. The severity of the bleeding is highly variable Chapter 26 Coagulation disorders / 353 Table 26. The bleeding risk shows incomplete correlation to severity of the deficiency, and bleeding only occurs after trauma such as surgery. Vitamin K deficiency Fat-soluble vitamin K is obtained from green vegetables and bacterial synthesis in the gut. Deficiency may present in the newborn (haemorrhagic disease of the newborn) or in later life. Deficiency of vitamin K is caused by an inadequate diet, malabsorption or inhibition of vitamin K by drugs such as warfarin which act as vitamin K Table 26. Deficiency of vitamin K-dependent factors Haemorrhagic disease of the newborn Biliary obstruction Malabsorption of vitamin K. Gamma-carboxylated glutamic acid binds calcium ions, inducing a reversible shape change in the N-termini of vitamin K dependent proteins. Warfarin interferes with the action of vitamin K epoxide reductase leading to a functional vitamin K deficiency. Haemorrhagic disease of the newborn Vitamin K-dependent factors are low at birth and fall further in breast-fed infants in the first few days of life. Liver cell immaturity, lack of gut bacterial synthesis of the vitamin and low quantities in breast milk may all contribute to a deficiency which causes haemorrhage, usually on the second to fourth day of life, but occasionally during the first 2 months. The platelet count and fibrinogen are normal with absent fibrin degradation products. For many years vitamin K has been given to all newborn babies as a single intramuscular injection of 1 mg. Following epidemiological evidence suggesting a possible link between intramuscular vitamin K and an increased risk of childhood tumours (which has not been substantiated), some centres recommended an oral regimen but this has never been subjected to randomized controlled trial. Vitamin K deficiency in children or adults Deficiency resulting from obstructive jaundice, pancreatic or small bowel disease occasionally causes a bleeding diathesis in children or adults.

Some people object to fluoridation and it is thought that too high a concentration, such as that achieved by highly fluoridated water and the use of a highly fluoridated toothpaste, may discolour the teeth of children. The first stage is called a primordial follicle, which then develops into a primary follicle and becomes a mature follicle by the sixth day of the period. This follicle secretes oestrogen until the ovum has developed to the point when it can break out, leaving the corpus luteum behind.

Also called frusemide furred tongue /f d t / noun a condition when the papillae of the tongue are covered with a whitish coating. Since the liver also secretes bile directly into the duodenum, the gall bladder is not an essential organ and can be removed by surgery. Sudden pain going from the right side of the stomach towards the back indicates that a gallstone is passing through the bile duct. He left no writings, and the ganglion was given his name by Anton Hirsch, one of his students, in his thesis of 1765.

The white matter of the spinal cord is vacuolated blood pressure medication losartan purchase 120 mg cardizem fast delivery, most severely in thoracic segments arrhythmia symptoms purchase cardizem 60 mg without prescription. Axons are involved to a lesser degree than myelin sheaths, and lipid-laden macrophages are present in abundance. Although the lesions in the spinal cord resemble those of subacute combined degeneration, levels of vitamin B12 and folic acid have been normal. The implications of this discovery are broad and extend even to the demyelinative and possibly the degenerative diseases. Spinal cord disease of this type has been reported from the Caribbean islands, southern United States, southern Japan, South America, and Africa. The clinical picture is one of a slowly progressive paraparesis with increased tendon reflexes and Babinski signs; disorder of sphincteric control is usually an early change. Paresthesias, reduced vibratory and position senses, and ataxia are the usual features. The upper extremities are usually spared (except for lively tendon reflexes), as are cerebral and brainstem functions. The diagnosis is confirmed by the detection in the serum of the antibodies to the virus. Neuropathologic study has documented an inflammatory myelitis with focal spongiform, demyelinative, and necrotic lesions, perivascular and meningeal infiltrates of inflammatory cells, and focal destruction of gray matter. The posterior columns and corticospinal tracts are the main sites of disease, most evident in the thoracic cord. It is strongly suspected but not established that the disease is due to the cytotoxic effect of the viral infection but autoimmune damage is an alternative possibility. There are anecdotal reports of improvement with intravenous administration of gamma globulin but these have not been consistent and had no effect in two of our patients. Myelitis Secondary to Bacterial, Fungal, Parasitic, and Granulomatous Diseases With few exceptions, this class of spinal cord disease seldom offers any difficulty in diagnosis. In most cases, the inflammatory reaction in the meninges is only one manifestation of a generalized (systemic) disease process. The spinal lesion may involve primarily the pia-arachnoid (leptomeningitis), the dura (pachymeningitis), or the epidural space. In some acute forms, both the spinal cord and meninges are simultaneously affected, or the cord lesions may predominate. Chronic spinal meningitis may involve the pial arteries or veins; and as the inflamed vessels become thrombosed, infarction (myelomalacia) of the spinal cord results. Chronic meningeal inflammation may provoke a progressive constrictive pial fibrosis (socalled spinal arachnoiditis) that virtually strangulates the spinal cord. In certain instances, spinal roots become progressively damaged, especially the lumbosacral ones, which have a long meningeal exposure. Interestingly, there are cases of chronic cerebrospinal meningitis that remain entirely without symptoms until the spinal cord or roots become involved. The infrequent but unique bacterial myelitis caused by the atypical pneumonia agent Mycoplasma pneumoniae has come to be viewed as a postinfectious immune disease, as discussed on page 601. At times it stands as a single pyogenic metastasis, but more often there has been spread from a contiguous infected surgical site or a fistulous connection with a superficial paraspinal abscess or a distant infection and subsequent bacteremia. As stated, spinal epidural abscess and granuloma are the more important representatives of this group. Sarcoid myelitis (see also page 613) Sarcoid granulomas may present as one or more intramedullary spinal cord masses, as in the cases reported by Levivier and colleagues. In our experience the granulomatous lesion, which may be focal or multifocal, simulates demyelinative disease with respect to its tendency to relapse and remit and in its notable but inconsistent response to corticosteroids (page 614). An asymmetrical ascending paraparesis and bladder disturbance have been the main features in our patients.
