[Family medicine as a career. Medical students’ attitudes and vocational choice motivations]

MOHOS András, VARGA Albert, MARKÓ-KUCSERA Mária, KALABAY László, TORZSA Péter

[INTRODUCTION - The large number of vacant general practices is a burning issue in Hungary. The entering of new colleagues into the general practitioner speciality training does not pose a real solution to the human resources crisis in this field. Our aim is to assess medical students’ attitudes and knowledge about general practice. SAMPLE AND METHOD - Cross-sectional survey with self-completed questionnaires at the University of Szeged, with the participation of 94 fourth and fifth year medical students in 2016 and 78 first and fourth year medical students in 2017. RESULTS - In 2016 1% of students planned for sure, and 16% planned probably to work as a general practitioner in the future. In 2017 3.9% of first-year students planned definitely to be a general practitioner, and 15.4% planned that probably. Among fourth-year students 0% of students planned for sure, and 19.2% planned probably to work as a general practitioner in the future. Whatever the presence of family medicine in undergraduate training influenced the medical students’ opinion about the profession positively (0.4-1.3 on a scale based on the direction and strength of the effects of certain factors ranging from -5 to +5). Those who were interested in family medicine considered the situation of healthcare significantly worse (p=0.027), than those who were not interested. To make the profession more attractive the following factors may play the most important role: the more intense presentation (I: 37%) of general practice in undergraduate training, improving the prestige of family medicine (IV: 31%), high-quality work (IV: 39%). CONCLUSIONS - Few medical students plan to work as general practitioner in the future. The most effective way to raise interest in family medicine is to increase the students’ knowledge and awareness of this specialisation, and the more intensive presentation of family medicine in undergraduate training is a key issue.]

[Psychological resources of positive aging ]

OLÁH Attila

[This study has four parts. In the first part of the study the career of successful aging construct has been presented through the literature of gerontology from Cicero until nowadays while highlighting the problems that were until now hindering the validation of that scientific construct. Suggestions for kin concepts instead of successful aging (e.g. active, optimal, vital, effective aging) have been reviewed in detail. The second part of the paper presents the results of longitudinal and cross sectional empirical studies about influencing factors of successful aging. The third part refers to the research outcomes of ageing people by the positive psychology and suggests the definition of positive aging as a state of good biological, psychological, social and spiritual functions which coincides with above average levels of psychological immunity and coping capacity and abilities of inventing successful strategies in the day-to-day practices. The fourth part of the paper describes an empirical study with 7,506 participants and demonstrates how the (emotional, psychological, social, spiritual) components of well being contribute to the maintaining of old-age physical and mental health further the psychological immunity, savoring capacity, positive orientation and flourishing. While comparing the flourishing levels of specific age groups there was a clear decline of individuals above 65 years with weakening psychological immunity. The study defines positive aging as the ability to maintain flourishing under fire of ageing associated challenges.]

[PAX2: lotium et visus sine pace]

VIOLETTA Antal, KERTI Andrea, JÁVORSZKY Eszter, MÁTTYUS István, REUSZ György, SZABÓ Attila, VÁRKONYI Ildikó, MAKA Erika, TORY Kálmán

[The autosomal dominant papillorenal syndrome results from primarily de novo mutations of PAX2. It encodes a transcription factor expressed in the kidney, urinary tract, nervous system, eye and the ear. Its haploinsufficiency causes primarily hypoplastic and hyperreflective kidney, or other forms of CAKUT. The clinical appearance may be dominated by nephrotic-range proteinuria with focal segmental glomerulosclerosis. The renal survival rate is highly variable: most of the recognized cases lead to ESRD during the first four decades of life. PAX2 mutations cause typical optic papillary alterations, most frequently papillary dysplasia. In contrast to the name of the syndrome, one fourth of the affected patients do not develop ocular involvement. Hearing impairment is associated in less than 10% of the patients. The affected members of the five families that we identified with PAX2 loss-of-function mutations, developed end-stage renal disease during the 2-4. decades of life.]

[Advance directive]

KŐMÜVES Sándor

[In the first step the work defines the institution of advance directive, places advance directive in the context of advance care planning, and demonstrates the advantages of advance care planning. Then the forms of the advance directive are presented and related Hungarian health care sections are interepreted in the context of these back-ground conditions. In the third step decision making capacity is defined, its standards are set out, the role of substituted decision maker is delineated. In the fourth step accumulated experience with living will is demonstrated and the possible alternatives concerning the future of living will are provided: the elimination of the living will part of the institution from health care or its continued application after substantial revision. METHODS - Analytic presentation after systematic review of the literature on the topic. RESULTS - Significant experience has been accumulated since the implementation of advance directive. In light of experience two attitudes have been chrystallized regarding the future of the institution: one takes the side of the elimination of the living will part of the institution from health care, the other recommends its revised application. CONCLUSION - The American and Hungarian experiences with advance directive recommend the review of the Hungarian institution of advance directive. ]

[Prevention and therapy of cervical cancer ]

RÉVÉSZ János, BÍRÓ Mátyás

[The global incidence of cervical cancer is ~530000, the death rate is ~270000 per year. These data shows, that cervical cancer is the fourth common malignancy in woman worldwide and the leading cancer related death in developing countries. HPV infection is the most important factor of carcinogenesis. Immunisation against HPV can prevent infection, and decrease the cancer incidence. In case of invasive cancer the therapeutic principles are surgery and radiotherapy. In case of high risk patients and/or locally advanced disease the adjuvant and neoadjuvant cytostatic treatment has limited evidences. The traditional cytotoxic therapy and the recent antiangiogenic therapy recommended for patients who have extrapelvic metastasis, residual tumor after primary radiotherapy or recidiv non curable tumor by radiotherapy or radical surgery.]

[Effects of ketodiet in fourth-stage chronic renal failure]

KÓSA Dezider, GELENCSÉR Éva, PALOTAI Ágota, GASZTONYI Beáta

[The well-known progressive nature of chronic renal failure can be slowed by low protein diet of various degrees. We applied standard 0.6g/kg body weight diet with supplement of essential amino acids and keto acids, 1 tablet/10 kg body weight Ketosteril was administered to 100 patient with IV. stage chronic renal failure for 31.5 months in average (10-63 month). During observational period 11% of the patients started hemodialysis program, 4 patients died. At the end of the observational period on basis of laboratory value of renal function 31% of patients had III, 50% IV, 19% V. stage chronic renal failure. We applied calculated glomerular filtration rate (ml/min/1.73 m2) for following the renal function. Average GFR value reduced from 24.9 to 23.63 ml/min/1.73 m2 (not significant). In case of female patients, we found a milder loss in renal function, average GFR was reduced from 24.8 to 24.6 ml/min/1.73 m2. We observed that women hold on the prescribed diet in greater ratio. On basis of the BMI value calculated at end of our examination no patient was undernourished. 25.8% of the patients had normal body weight, 54.3% had overweight, 17.5% was obese and 2.4% severely obese. We followed the changes in state of nourishment by serum albumin value, average serum albumin was 42.92 g/l at beginning and did not change significantly (42.81 g/l at the end of our examination). Applying keto diet is safe and efficient in slowing the progression of severe chronic renal failure and improves the state of nourishment. Good state of nourishment achieved in predialytic stage is associated with low mortality ratio and gives opportunity to lower the mortality of patients starting dialysis program.]

Vitreous humor diffusion measurements from diffusionweighted imaging in idiopathic intracranial hypertension

CAGLI Bekir, TUNCEL Alpaslan Sedat, YILMAZ Erdem, TEKATAS Aslan, ERMIS Veli

Background - Idiopathic intracranial hypertension is a disease with uncertain etiology. It is not caused by an intracranial mass lesion or hydrocephalus and is characterized by abnormal elevation of intracranial pressure and normal composition of the cerebrospinal fluid. The orbita and intracranial area are closely related anatomically. Elevated intracranial pressure can be transmitted to the orbita through the cerebrospinal fluid around the optic nerve sheath changes at the vitreous humor on diffusion-weighted imaging have not been systemically studied in idiopathic intracranial hypertension. Purpose - The purpose of this study was to investigate diffusion changes in the vitreous humor in patients with intracranial hypertension. Methods - In this retrospective study, 25 patients with papilledema and who had been definitively diagnosed with idiopathic intracranial hypertension and 20 control participants were evaluated. Control subjects and patients were scanned with a 1.5 Tesla magnetic resonance imaging. Apparent diffusion coefficient maps were obtained from diffusion-weighted imaging with a b value of 1000 s/mm2 and apparent diffusion coefficient values were automatically calculated. These images were obtained by a radiologist who was blinded to the details of the study for center of each vitreous humor and the body of lateral ventricle. The mean apparent diffusion coefficient values of each vitreous humor and the body of the lateral ventricle were calculated for each group (control group and patients) and quantitative comparisons were performed. Results - There were no statistically significant differences in mean apparent diffusion coefficient values of the right vitreous humor, left vitreous humor and the body of the lateral ventricle between the patients with idiopathic intracranial hypertension and the control group (p=0.766, p=0.864, p=0.576, respectively). Discussion - Vitreous humor is a closed system and has no direct relationship with the cerebrospinal fluid or cerebral tissue and although morphological changes occur in the orbital structures, including the optic disk and optic nerve in idiopathic intracranial hypertension, the indirect effects of these changes on the vitreous humor may be too subtle to measure. Conclusion - We did not find a significant difference in the mean apparent diffusion coefficient value of the vitreous humor between the patients with idiopathic intracranial hypertension and the control group. However, future studies will be necessary to determine if changes in the vitreous humor can be used to diagnose intracranial hypertension.

[Hypertension and left ventricular hypertrophy]

MATOLTSY András

[Left ventricular hypertrophy (LVH) is defined as an increase in the mass of the left ventricle. In addition to the absolute increase in mass, the geometric pattern of LVH also may be important. LVH can be secondary to an increase in wall thickness, an increase in cavity size, or both. LVH as a consequence of hypertension usually presents with an increase in wall thickness. This increase in mass predominantly results from a chronic increase in afterload of LV caused by the hypertension, although there is also a genetic component. A significant increase in the number and/or size of sarcomeres is the main pathologic mechanism, but hypertension may also result in interstitial fibrosis. The estimation of mass is commonly derived from measurements obtained by echocardiography. LVH is associated with increased incidence of systolic and/or diastolic dysfunction, heart failure, myocardial infarction, ventricular arrhythmias, sudden cardiac death, aortic root dilatation, and a cerebrovascular event. The cardiovascular risk is directly related to the degree of mass. The regression of LVH is associated with a reduction in cardiovascular risk and improved cardiac function. Regression of LVH is associated with weight loss, dietary sodium restriction, and use of ACE inhibitors, ARBs, some calcium channel blockers, and some sympatholytic agents.]

[Effects of peripheral resistance lowering and elevating beta-blockers on central blood pressure - nebivolol in focus]

BENCZÚR Béla

[Central blood pressure, that is, blood pressure (BP) in the ascending aorta, is considered an important physiologic parameter as it reflects the hemodynamic relationship between the heart and the aorta, both in systole and in diastole. In the systolic phase, central BP represents the pressure against which the left ventricle has to eject blood during systolic contraction. Thus, central arterial pressure reflects both left ventricular stroke volume and afterload, defines cardiac work, and contributes to the development of left ventricular hypertrophy in hypertensive individuals. In the diastolic phase, central BP is a key determinant of the blood flow delivery to the myocardium. Despite the increasing knowledge regarding the importance of central blood pressure and the availability of non-invasive measurement technics it couldn’t spread in everyday clinical practice and rarely or not mentioned in the therapeutic guidelines. The different antihypertensiv drugs significantly differs based on their effects on central blood pressure particularly β-blockers. The so-called ’classical’ β-blockers have un - favourable effect on central blood pressure due to increasing peripherial vascular resistance. In the opposit the vasodilating β-blockers including nebivolol markedly decrease central blood pressure which could explain their beneficial effects.]
