[The incidence of colorectal cancer has dramatically increased in the past decades, rendering it the second most frequently diagnosed cancer in the Western world. Disease outcome can be improved both by early diagnosis, e.g., through the introduction and extension of screening programs, and by increased therapeutic efficiency. The latter is achieved by increasing the radicality of interventions in surgical oncology to total mesorectal excision, thereby significantly decreasing the frequency of local recurrence. High ligation of the inferior mesenteric artery aims to enhance the efficiency of lymphadenectomy. With the introduction of techniques that spare vegetative nerves, the quality of life will not be adversely affected by the increased radicality. Another direction of progress in colorectal surgery is the increased use of minimally invasive approaches, such as local excision by transanal endoscopic microsurgery or laparoscopic methods. Increased acceptance of a multimodality approach, i.e., combined application of surgical and oncological methods in the treatment of colorectal cancer, has been a great step forward recently. Beyond the long-applied adjuvant treatments, the pre-surgical use of neoadjuvant chemo-radiotherapy has become standard for locally advanced rectal cancers. Adjuvant and neoadjuvant chemotherapy also supplements the surgery of metastases with improving results and impressive long-term survivals. A very important prerequisite for tailored multimodality treatment is reliable staging, which is facilitated by the wider availability of endorectal ultrasound.]

[Thyroid cancers derived from follicular epithelial cells are histologically classified as papillary, follicular and anaplastic. Cancers that originate from parafollicular, or C-cells, are termed medullary carcinomas. Their annual incidence is fairly low; 3 to 7 cases per 100 000 people. After the Chernobyl disaster, however, thyroid cancers have received much attention. They often occur at young age, and frequently and early give metastases. They typically grow slowly and have a good prognosis even in the metastatic stage. The main prognostic factors include age, tumour size and extent, the completeness of surgical removal, distant metastases and tumour grade. Based on these parameters, they are classified into high-risk and low-risk groups. There are no prospective randomized studies available on the optimal treatment of thyroid cancers. Their biological aggressiveness differs according to geographic location, which explaines why the management of thyroid carcinomas has not been standardized internationally. Contrary to America and Australia, in Europe there are several endemic goitre regions, and background radiation is higher. It is generally accepted that here the standard therapy of choice is total thyreoidectomy with adequate lymph node dissection followed by postoperative radioiodine ablation. It is a reasonable demand to minimize the higher morbidity associated with radical surgery (e.g., recurrent nerve palsy, postoperative hypoparathyroidism) below 1%. It is recommended that such operations are performed by experienced thyroid surgeons in centres with multidisciplinary endocrine teams.]

[Association between cyclothymic affective temperament and hypertension]


[Affective temperaments (cyclothymic, hypertymic, depressive, anxious, irritable) are stable parts of personality and after adolescent only their minor changes are detectable. Their connections with psychopathology is well-described; depressive temperament plays role in major depression, cyclothymic temperament in bipolar II disorder, while hyperthymic temperament in bipolar I disorder. Moreover, scientific data of the last decade suggest, that affective temperaments are also associated with somatic diseases. Cyclothymic temperament is supposed to have the closest connection with hypertension. The prevalence of hypertension is higher parallel with the presence of dominant cyclothymic affective temperament and in this condition the frequency of cardiovascular complications in hypertensive patients was also described to be higher. In chronic hypertensive patients cyclothymic temperament score is positively associated with systolic blood pressure and in women with the earlier development of hypertension. The background of these associations is probably based on the more prevalent presence of common risk factors (smoking, obesity, alcoholism) with more pronounced cyclothymic temperament. The scientific importance of the research of the associations of personality traits including affective temperaments with somatic disorders can help in the identification of higher risk patient subgroups.]

The prevalence of sarcopenia and dynapenia according to stage among Alzheimer-type dementia patients

YAZAR Tamer, YAZAR Olgun Hülya

Aim - In this study, the aim was to identify the prevalence of sarcopenia and dynapenia according to disease stage among Alzheimer-type dementia (AD) patients and collect data to suggest precautions related to reducing the disease load. Method - The study was completed with 127 patients separated into stages according to Clinical Dementia Rating Scale (CDR) criteria and 279 healthy volunteers aged 18-39 years and 70-80 years abiding by the exclusion criteria who agreed to participate in the research. Our prospective and cross-sectional study applied the CDR and mini mental test (MMSE) to patients with disorder in more than one cognitive area and possible AD diagnosis according to NINCDS-ADRDA (National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer’s Disease and Related Disorders Association) diagnostic criteria. The patient and control groups had skeletal muscle mass index (SMMI), muscle strength and physical performance assessed with sarcopenia diagnosis according to European Working Group on Sarcopenia in Older People (EWGSOP) diagnostic criteria. Results - In our study, in parallel with the increase in disease stage of AD patients, the prevalence of sarcopenia (led by severe sarcopenia) and dynapenia was higher compared to a control group of similar age. Conclusion - In chronic, progressive diseases, like AD, identification of changes in parameters, like muscle mass and strength and reductions in physical performance in the early period, is important for identification and to take precautions in the initial stages considering the limitations of the preventive effects of treatment applied after diagnosis of AD.

[Avoiding unlimited energy drink consumption is a matter of our heart]


[Energy drinks have been gaining unbroken popularity, especially among youngsters and children since they were introduced to the market. Manufacturers promise to improve performance and stamina with consuming the products, classified as non-alcoholic soft drinks. In addition to the vitamins and plant extracts, they contain a significant amount of caffeine and other stimulants (taurine, guarana). Among the active ingredients, caffeine has an outstanding effect and thereby a danger, since its overconsumption – in addition to milder he­mo­dynamic changes – can cause severe cardio­vascular consequences, cardiac arrhythmias, ion channel diseases, increased blood coagulation, myocardial infarction or reduced cerebral blood flow in susceptible consumers. Many case studies have also reported serious cardiovascular attacks among young chronic energy drink consumers. Health impairments of excessive and long-term consumption of energy drinks have been studied increasingly, however there is limited and contradictory evidence on the safety of consumption and the effectiveness of performance enhancement. ]

Mid-term oral isotretinoin therapy causes a predominantly sensory demyelinating neuropathy

ALTUN Yasar, INAN Esra

Aim - The purpose of this prospective study was to investigate whether mid-term treatment with oral isotretinoin may impact peripheral nerve function. Methods - In this study, we included 28 patients with no apparent neurological or neurophysiological findings. The patients received treatment with oral isotretinoin for papulopustular or nodulocystic acne. The patients with normal findings in the first examination were given 1 mg/kg/day oral isotretinoin. Neurological examinations and electroneurographic studies were performed before and 6 months after the onset of isotretinoin treatment. Results - Clinical examinations and electroneurographic evaluations prior to treatment revealed no abnormalities in any of the patients. However, 20 patients (72%) displayed one or more abnormal values in the tested parameters after treatment. Although the mean amplitudes of compound muscle action potential of the ulnar and median nerves did not vary, significant decreases were observed in the mean sensory conduction velocities of median, ulnar, sural, medial plantar, medial dorsal cutaneous, and dorsal sural nerves 6 months after the onset of treatment. Conclusion - Systemic use of isotretinoin may cause electroneurographic changes. Probable electroneurographic alterations may be detected at a much earlier period via dorsal sural nerve tracing when electrophysiological methods used in routine clinical practice cannot detect these changes.

[Introduction: New-onset diabetes after transplantation (NODAT) is one of the most common complications following kidney transplantation. The diagnosis of NODAT is often late or missed, therefore it impairs the implanted renal allograft. Patients and methods: Patients were randomized to receive cyclosporine A- or tacrolimusbased immunosuppression. One year after the transplantation, fasting and oral glucose tolerance tests were performed, and the patients were assigned to one of the following three groups based on the results: normal, impaired fasting glucose/impaired glucose tolerance (IFG/IGT), NODAT. Age, laboratory results, renal function, morphological abnormalities, and changes in the Banff score were evaluated. Results: NODAT developed in 14% of patients receiving cyclosporine A-based immunosuppression and in 26% of patients taking tacrolimus (p=0.0002). Albumin levels were similar, but uric acid level (p=0.002) and the age of the recipient (p=0.003) were significantly different between the diabetic and the normal group. The evaluation of renal function showed no significant differences in case of serum creatinine level, eGFR, and urea level. Evaluation of tissue samples revealed that acute cellular rejection (ACR) and interstitial fibrosis/ tubular atrophy (IF/TA) were significantly different in the NODAT group. Changes in the Banff score provided significant difference regarding tubulitis (“t”) and interstitial inflammation (“i”) (p=0.05). Discussion: The pathological effect of new-onset diabetes after kidney transplantation can be detected in the morphology of the renal allograft earlier, before any signs of functional impairment.]
