[Detection of endemic MRSA colonisation in a retirement home]


APRIL 20, 2013

Lege Artis Medicinae - 2013;23(03-04)

[Methycillin-resistant Staphylococcus aureus (MRSA) colonisation was proved in a retirement home. A resident of the social institution (a 83-year-old man) was hospitalised and was cared for in a ward where a patient positive for MRSA was treated. Screening tests of the above mentioned resident, one of his room-mates at the retirement home as well as three of the four nurses being on duty at the weekend when the man returned to the social institution from the hospital proved the presence of MRSA colonisation. The screening test, which had been extended to the whole staff due to epidemiological reasons and also because of their anxiety, revealed MRSA positivity in the throat and nasal mucus of a fourth nurse. We presumed that the patient released from the hospital had infected his roommate as well as the four nurses. In order to investigate the epidemiological correlations we requested the cultured strains to be typified. With the use of phage typification, three different types of MRSA strains were identified in the six persons positive for MRSA, and a further MRSA strain could not be typified with the basic phage sequence. We review some interventions with regard to the avoidance and prevention of methycillin- resistant Staphylococcus aureus infection, which we had the opportunity to order as well as implement at the retirement home. We raise some of the problems we encountered.]

[Non-pharmacological prevention and treatment for postoperative delirium in elderly patients with hip fracture - a systematic review]

VIDA Nóra, PAPP László

[Delirium is defined as a disturbance of consciousness and cognition that develops over a short period of time and fluctuates over time. During the last decade, the number of publications dealing with different aspects of delirium have been grown. The key points in most articles are pharmacological prevention and treatment, but because the rise of health care expenditures, all activities, which cost-effectively support the care process, is getting more and more important. The aim of the study: The aim of this research is to review the non-pharmacological prevention and treatment possibilities of delirium in elderly patients undergoing hip surgery. Systematic review, using articles published between 1999 and 2019 in PubMed and Wiley Online Libraries. Non-pharmacologic treatments significantly reduced the incidence (p=0.003–0.045) and duration (p=0.009–0.03) of delirium. The interventions also contributed to decrease the number of episodes (p=0.03), and to make the symptoms lighter. Early mobilisation and adequate fluid and electrolyte intake are key factors in reducing the incidence of delirium. Measuring oxygen saturation and support, appropriate nutrition, effective pain treatment, minimizing drug-interactions, maintaining good sleep and managing sensory dysfunctions have an effect on incidence, duration and severity of delirium.]

[Insulin: alfa and omega]

KIS János Tibor, BALOGH Bernadett, KISS Zsófia, SCHANDL László

[Type 1 diabetes (T1DM) is caused by the autoimmune death of insulin-producing β-cells. In the background there is by all probability the primary antigen (if the theory of primary antigen is correct) the insulin itself or the proinsulin. However, treatment of T1DM is virtually equivalent to the insulin treatment. The earlier we recognize T1DM and start treatment, the better gly­caemic results we achieve, the more likely we can maintain all functional β-cell stocks. Insulin also plays a key role in the immunopathogenesis, development and treatment of T1DM, thus insulin is the alpha and omega in this condition.]

[Paradigm shift in the treatment of osteoarthrosis and the importance of prevention today]

DÖMSE Eszter

[Osteoarthrosis is a major burden on our society, both in terms of health affairs and health economy. The increasing strain on joints by competitive sports and the grow­ing prevalence of sedentary lifestyle are coupled main factors behind the increas­ing occurence of osteoarthritis in younger generations. Its pathomechanism is re­cently recognised to be a combination of inflammatory and degenerative processes. Concerning the serious and even quality of life worsening outcomes and its growing and spreading prevalence, the role of prevention has become crucial. This study reviews the preventive options, emphasiz­ing the importance of recreational sport and physical activities, while presenting also the new generation of chondroprotective agents. ]

[Ways of treatment in traditional, complementary and integrative medicine of COVID-19]

SZÔKE Henrik, DARÓCZI Zoltán, VERZÁR Zsófia

[This study presents the results and expert opinions about the most important, amply evidence based, most widespread and af­fordable therapeutic procedures and supp­lementary preparations, which may support or and possibly replace conventional treatments. Traditional, complementary, and integrative medicine offers a number of options to enhance physical, psychic and mental resilience that may also be useful in the prevention and treatment of COVID-19 patients. It will be worthwhile to analyse the evidences of clinical experiences on potential benefits. This brief summary might serve as a useful starting point for further research on this topic.]

[Changes in systolic blood pressure in the Hungárián aduit population between 2010 and 2018 based on public health screening data]


[Using our mobile public health screening system, we examined the changes in systolic blood pressure averages and systolic pressure distribution between 2010 and 2018 by analyzing the data of 72,857 women (mean age 42.3±13.9 years) and 61,563 mén (mean age 42.2±13.9 years) in three consecutive time periods. The SBP averages have been gradually and significantly decreased since 2010 in all age groups. The parametric and non-parametric characteristics of the systolic distribution curves alsó showed a favorable change during the indicated period. The observed changes may indicate that the primary and secondary prevention, as well as the treatment of hypertension and the physician-patient cooperation in Hungarywere successful in the indicated period.]
