Lege Artis Medicinae - 2012;22(03)

[Irritable bowel syndrome (IBS) is one of the most common gastrointestinal condition, which affects 10-15% of adults in developed countries. Recent observations have raised the possibility that disturbances in the gut microbiota and/or the accompanying low-grade inflammatory state might contribute to the etiology and symptomatology of irritable bowel syndrome. Some studies indicate that small intestinal bacterial overgrowth (SIBO), as confirmed by hydrogen breath tests (HBT), is more prevalent in patients with irritable bowel syndrome than in matched controls without IBS. Although the data are conflicting, this observation has led to the hypothesis that bacterial contamination was the primary cause of IBS. As a consequence of this hypothesis, a lot of therapeutic options have found their way into the armamentarium of those who treat patients with IBS. These agents include probiotics, prebiotics, antibiotics and anti-inflammatory agents. This paper describes the various mechanisms by which changes in the gut flora might contribute to IBS and also discusses the efficacy and safety of antibiotic therapies, especially rifaximin, for treating IBS/SIBO symptoms.]

[Clinical aspects of ischaemic bowel disease]


[Decreased blood flow through the intestines leads to mesenteric ischaemia, which is characterised by cellular damage due to the lack of oxygen and nutrients. Extensive collateralisation between splanchnic vessels serves as a protective mechanism against ischaemia. Intestinal ischaemia can be classified on the basis of its timing, location and the vessels involved. Acute mesenteric ischaemia can result from arterial embolisation, arterial or venous thrombosis, or vasoconstriction secondary to systemic circulation disorder associated with hypovolaemia. Chronic mesenteric ischaemia develops as a consequence of partial or complete occlusion of splanchnic vessels. Colonic ischaemia is mainly caused by a limited circulation disorder of the inferior mesenteric artery. Mortality rates for the various forms of acute mesenteric ischaemia are different. However, early diagnosis before bowel infarction might improve survival. This paper summarises the cilical aspects, diagnosis and therapeutic options of intestinal ischaemia.]

[What is the doctor like, if female? - Female doctors’ ideal image based on empirical studies]

MOLNÁR Regina, GIRASEK Edmond, CSINÁDY Adriána, BUGÁN Antal

[The aim of our study was to examine thestereotypes about female doctors and howdo the female medical students perceivethe working female doctors whom are theirrole models. In the first study (247 from theAlbert Szent-Györgyi Medical and Pharma-ceutical Centre at the University of Szegedand 256 from the Medical and HealthScience Centre of the University ofDebrecen) the female medical students’professional socialization was compared tothe male counterparts’. In the second study(from University of Szeged, 214 femalemedical students, 132 female jurist stu-dents) female medical and jurist students'professional socialization was comparedincluding the comparison of stereotypes inconnection with working female doctorsand jurists. Female medical students’ professionalsocialization is different that of male coun-terparts in several aspects: being morealtruistic, more family centered, gettingcommited to the profession earlier, havingmore ambiguous carrier planes, and asmaller percentage of their parents’ has adegree or is a medical doctor, then for malemedical students. The female medical doc-tor has positive, idealistic, altruistic charac-ters according to both female studentgroups’ opinions. The female doctor’simage is more often associated with char-actersitics implying problems by femalemedical students then jurists. The unfold-ing image of these stereotypes is a femaledoctor who is willing to help, however,faceing lots of hardnesses during work.If the female medical students’ image of theproblematic life of these idealistic femaledoctors’ is known, it provides an opportu-nity to prepare them for the hardnessesthey’ll face avoiding role conflicts andhealth problems in the future.]

[Possibilities of applying basis/bolus method in treatment of adolescent with type 1 diabetes mellitus]


[INTRODUCTION - Since the end of the pastcentury, the basis/bolus method has been adeterminate factor of adjusting insulin thera-py. Experiences with insulin pump treatmentprove that well-quantified and adequatelytimed basal insulin treatment can fully com-pensate for the diurnal glucose-producingactivities of the liver and the diurnal changesin the activity of insulin receptors. Suitablyselected basal insulin treatment can, there-fore, keep the changes in blood sugar levelthat are dependent of the diet’s carbohydratecontent well under control. CASE REPORT - By presenting the approxi-mately five-year treatment of an adolescentboy, the author presents the current options(and failures) of insulin therapy that might beused with more or less success. Each treat-ment approach had its place in the variousstages of the patient’s diabetes. Nevertheless,insulin pump therapy, admittedly the moststate-of-the-art method today was unsuccess-ful due to patient’s lack of compliance, thusthis treatment had to be stopped. Still, on thebasis of the experiences with insulin pumptherapy, the restored intensive-conservativetreatment was set up on glargine basalinsulin, defining doses of bolus in correlationwith 10 grams of carbohydrate, which madethe diet less strict. This approach resulted ina considerable improvement of the patient’smetabolic profile. CONCLUSION - The right choice of thedoses and efficacy curve of basal insulin isessential for achieving a good metabolic bal-ance during intensive-conservative therapy.In case of deteriorating metabolic balance,suspending the inefficient insulin pump ther-apy is justified and means no disadvantagefor the patient, as long as the subsequentadjustment is prudent. By defining doses of ashort-acting bolus insulin analogue in corre-lation with carbohydrate intake along withglargine therapy permits adaptation to themetabolism of patients with poor compli-ance and unsatisfactory lifestyle - in expec-tation of better results. ]

[Reversible hepatocerebral degeneration-like syndrome due to portovenous shunts]


[Ataxia and tremor are rare manifestations of hepatocerebral degeneration due to portovenous shunts. Ammonia is a neurotoxin that plays a significant role in the pathogenesis of hepatic encephalopathy. A 58-year old male patient was assessed with the complaints of gait disturbance, hand tremor, and impairment of speech. His neurological examination revealed dysarthric speech and ataxic gait. Bilateral kinetic tremor was noted, and deep tendon reflexes of the patient were hyperactive. Serum ammonia level was found to be 156.9 μg/dL. Cranial magnetic resonance (MR) imaging revealed increased signal intensity in bilateral globus pallidus on T1-weighted axial sections, and bilateral prominent hyperintense lesions in the middle cerebellar peduncles on T2-weighted axial sections. On his abdominal MR portography, multiple portohepatic venous collaterals were noted in the right and left lobes of liver parenchyma in 2D FIESTA axial MR sections. To our knowledge, we reported the first case of acquired hepatocerebral degeneration presenting with cerebral symptoms without any hepatic findings in which clinical improvement was noted, and hyperammonemia disappeared following medical treatment.]

[Crohn’s disease is a chronic inflammatory disorder which may affect any part of the gastrointestinal tract. Its pathogenesis is only partially understood; various environmental and host (e.g., genetic, epithelial, immune and nonimmune) factors are involved, together initiating a chronic uncontrolled inflammation, which is partly due to an imbalance between pro- and anti-inflammatory cytokines, and a defective apoptosis of lamina propria T cells. Among proinflammatory cytokines, tumour necrosis factor- α (TNF-α) seems to play a central role in Crohn’s disease. Over the past years, the increasing knowledge on the pathogenesis of Crohn’s disease has led to the development of a number of biological agents targeting specific molecules involved in gut inflammation, including TNF-α and its receptors. This paper reviews the rationale for the use of TNF-α inhibitors in the treatment of Crohn’s disease.]

[Role of β-blockers, especially carvedilol in the treatment of hypertension]

PÁLL Dénes, MARODA László, ZRÍNYI Miklós

[Changes in hypertension guidelines in the past years have affected the clinical thinking about β-blockers. Authors reviewed the development of β-blockers emphasizing the differences across various active pharmaceutical agents. Different hemodynamic and metabolic effects are being discussed in details for the third ge - neration vasodilatator carvedilol. Carvedilol has no effect on cardiac output but decreases peripheral vascular resistance which results in lower blood pressure values. However, carvedilol, opposite to unfavorable effects of traditional β-blockers, has a neutral impact on both carbohydrate and lipid metabolisms. Its more advanced cardiac effects include decreased left ventricular hypertrophy and increased coronary flow reserve. Vasodilatator type β-blockers (carvedilol, nebivolol) are indicated in the combi - nation treatment of hypertension, especially when the patient has heart failure, coronary disease or suffered from a previous heart attack.]

[Currently, Cotrel-Dubousset spondylodesis is the treatment of choice in orthopaedics. It allows for correction of deformity in three-dimensions allowing for stable fixation. EOS (Extended Orthopedic System) is an ultra low dose X-ray imaging system, simultaneously acquiring images of the whole body in two planes. Examinations with the EOS system is not only indicated in cases related to orthopaedics but in multiple other conditions owing to its low level of emitted radiation with rapid and cost-effective imaging. The importance of EOS examination is emphasized in systemic skeletal disorders, thus allowing itt o be used in various other clinical fields.]

[Idiopathic inflammatory myopathies are systemic autoimmune diseases with an immune-mediated inflammation of the striated muscles which lead to progressive muscle weakness. Their cause is still unknown, but recently the understanding of the molecular immunopathology has improved, which may as well offer therapeutic targets in the future. The aim of this review is to present currently available data on the most important factors and processes that are involved in the pathogenesis of these diseases. Although glucocorticoids remain the cornerstone of the treatment for the major forms of idiopathic inflammatory myopathies, there are other efficacious immunosuppressive agents with fewer side effects. The authors discuss classic treatment regimens as well as more recent therapeutic approaches.]
