[Indeed, the words of János Csere Apáczai, spoken more than three hundred years ago, seem to echo the problems of our present day! Beyond space and time, it is perhaps worth reflecting on his noble thoughts, delivered with a noble eloquence and soaring eloquence! ]

[Malnutrition syndrome in childhood part I.]

BAKSAI László, PHILIP W. H. Eskes

[Malnutrition is a chrocic nutritional disorder resulting from insufficient intake of caloric energy and/or some the fundamental nutrients. Since it is the most common public health problem in the world it has a great impact on pediatric morbidity and mortality. The etiology is extremely complex. When one considers the less severe symptoms and signs caused by vitamin-, mineral-, and trace element deficiencies, it is apparent that not only children living in underprivileged countries are affected. In the course of making the diagnosis an assessment of the nutritional status should also be made, especially considering the above-mentioned marginal nutritional deficiencies. The most common manifestation of nutritional disorders is anemia, which is mostly caused by lack of iron, vitamin B12, folic acid and can be complicated by infections. Nutritional requirements can be affected by several drugs. That is why this medication-nutrition interaction has to be kept in mind during treatment. The interaction of malnutrition and infection is very important, primarily for three reasons: mechanisms by which infection complicates the metabolic and nutritional status of the host; importance of suboptimal nutritional status on susceptibility and severity of intercurrent infections; clinical and therapeutic implication of these interactions. ]

[The bleeding time]

BODA Zoltán

[The bleeding time is considered to be the best screening test for the detection of disorders of primary haemostasis. Despite a large number of bleeding time tests, the exact pathophysiological background of the prolonged bleeding time is unknown. The significance of the cellular (platelet) von Willebrand protein is emphasized. A sensitive method (Ivy) and standardized devices (Simplate) are suggested. Examination of the bleeding time in cases of von Willebrand disease and congenital or acquired thrombocytopathy is essential. Specific recommendations regarding the rational use of the bleeding time (diagnostic algorythm) are presented. ]

[P300 wave evoked by visual and acustic stimuli in parkinsonian patients with or without dementia]

MOGYORÓS Ilona, SZOMBATHELYI Éva

[Authors analysed the relationship between cognitive function disturbance observed in patients with Parkinson's disease and clinical features of the disease. Relationship between the latency prolongation of the P 300 wave and the duration of substitution therapy, clinical form and severity of the disease (the Hoehn-Yahr stage) was examined. 75 randomly selected young patients with Parkinson's disease were divided in to two groups: one with and the other without dementia as determined by the Wechsler. Hunt and Mini Mental State tests. The latency of the P 300 wave using visual and acoustic stimuli was determinated. Significant prolongation of the latency of P 300 wave evoked both by visual and acoustic target stimuli was found in parkinsonian patients with dementia. Patients with dementia have longer duration of disease and substitution therapy. The akinetic-rigid form of the disease was more frequent in this group as well. A significant part of younger patients are chacarterised not only with motor but with cognitive function disturbance, too. Determination of the latency of P 300 wave helps to select these patients and to choose the adequat therapy. ]

[Acetylsalicylic acid (ASA) 75 or 100 mg? ]

KIS János Tibor, ZSIGMOND Kálmán

[The acetylsalicylic acid (ASA) is one of the oldest and most widely used drugs in the world. Currently, it is the most commonly used for the treatment and prophylaxis of cardiovascular diseases. Today, there has been consensus that the risk of ASA’s side effects in primary prevention is greater than the expected benefits. However, it maintains its leading role in the secondary prevention of cardiovascular diseases. There is also a consensus that small doses are recommended for preventive purposes, but there is no agreement whether it should be 75 or 81 or 100 mg. The authors summa­rize the publications published in this topic. ]

[Current diagnosis and treatment of membranous nephropathy]

STUDINGER Péter, CSEPREKÁL Orsolya, FINTHA Attila, KARDOS Magdolna, TISLÉR András

[Primary membranous nephropathy is a common glomerular disorder characterized by subepithelial immune deposits. The pathomechanism underlying these lesions has only recently been elucidated: M-type phospholipase A2receptor (PLA2R) protein emerged as being the leading autoantigen. Antibodies to PLA2R, typically of IgG4 subclass are expressed in 70-80% of patients with primary membranous nephropathy. The level of autoantibody to PLA2R was shown to correlate with disease severity and to change parallel with disease activity in response to therapy. While mild forms of the disease are prone to spontaneous remission and carry excellent prognosis, severe forms often progress into end-stage renal disease without treatment and necessitate immunosuppression. The latest guidelines recommend the application of corticosteroids with alkylating agents or calcineurin inhibitors as first-line therapy. Promising new therapies that are currently being explored for this disease include rituximab, mycophenolate mofetil, and adrenocorticotropic hormone.]

[Systemic ANCA-associated vasculitis. Induction immunosuppression therapy, complications and outcome. Part 1]

HARIS Ágnes, POLNER Kálmán

[The present review is compiled of two parts, the first part aims to summarize the induction immunosuppressive therapy, the second part delineates the outcome and complications of ANCA-associated vasculitis. ANCA-associated vasculitis is a systemic disease, accompanied with rapidly progressive glomerulonephritis and severe, often life-threatening extrarenal complications. By early diagnosis and immediate initiation of immunosuppressive therapy, both patient and renal outcome have been substantially improved. The major aims of modern therapeutic protocols are, besides improving survival, to decrease immunosuppressive drug toxicity and avoid infections. Immunosuppression is based on the combination of large dose of corticosteroid and cyclophosphamide, which is advisable to supplement by plasma exchange. The B-cell depleting anti-CD20 monoclonal antibody rituximab, which has already been available in Hungary, has been proved to be similarly effective in newly diagnosed ANCA-vasculitis, and even more effective in a relapsing disease, compared to cyclophosphamide. Amongst rituximab’s further indications in this disease is the preservation of young women’s fertility, and it also has priority in some other special cases. Early diagnosis and prompt immunosuppressive treatment have resulted that ANCAvasculitis became a treatable disease with reasonably good clinical outcome, yet both the disease and the immunosuppressive medications frequently cause complications, which necessitate continuous alertness of the attending nephrologists.]

[Solid organ transplantation and malignancies]

VÉGSŐ Gyula, MÁTHÉ Zoltán

[Recent breakthroughs in the fi eld of organ transplantation and oncology have challenged existing views, and necessitate the revision of several tumor-related issues in transplantation. The need for expanding the donor pool raises the question of how and when it is plausible to transplant the organs of a donor with a history of cancer, such that the risk of tumor inoculation and manifestation due to the graft would be minimal for the recipient. Another point to consider is whether it is acceptable to transplant a recipient with a history of a malignant tumor, and if yes, how much tumor-free survival time is required as a minimum before the transplant. Transplanted patients live longer as a result of modern immunosuppressive therapy. However, the risk of malignant tumors increases proportionally to the length of the immunosuppressed state: their incidence may be as much as 20-30% in the long term. The signifi cance of „de novo” posttransplant tumors is highlighted by the fact that they are among the leading causes of death in transplant patients. Taken together, malignant diseases pose a serious problem from several aspects, the solution for which requires close teamwork of experts in oncology and transplantation, and the integration of up-to-date knowledge in the process of making a therapeutic decision, tailored individually for the patient.]

[Necessity of a shift in attitudes in the judgment and therapy of skin and soft-tissue infections]

SZALKA András

[Skin and soft-tissue infections are defined as infections of the epidermis, dermis, or subcutan tissue. They are among the most common human bacterial infections observed in clinical practice. It has also been shown that the incidence of skin and soft-tissue infections is increasing. This has been attributed to several factors, including increasing population age, surgical wounds related to more invasive surgery in the ageing population, obesity, malnutrition, diabetes, peripheral vascular disease and decreasing immunocompetence. There has been a major increase in the occurrence of Staphylococcus aureus infections, and communityacquired methicillin-resistant S. aureus (MRSA) infections in particular. Although many cases of skin and soft-tissue infections can be successfully treated using empirical antimicrobial therapy, changing resistance patterns of S. aureus isolates necessitate new treatment strategies.]
