Human pancreatic ductal organoids with controlled polarity provide a novel ex vivo tool to study epithelial cell physiology.

Epithelial ion and fluid secretion determine the physiological functions of a broad range of organs, such as the lung, liver, or pancreas. The molecular mechanism of pancreatic ion secretion is challenging to investigate due to the limited access to functional human ductal epithelia. Patient-derived organoids may overcome these limitations, however direct accessibility of the apical membrane is not solved. In addition, due to the vectorial transport of ions and fluid the intraluminal pressure in the organoids is elevated, which may hinder the study of physiological processes. To overcome these, we developed an advanced culturing method for human pancreatic organoids based on the removal of the extracellular matrix that induced an apical-to-basal polarity switch also leading to reversed localization of proteins with polarized expression. The cells in the apical-out organoids had a cuboidal shape, whereas their resting intracellular Ca2+ concentration was more consistent compared to the cells in the apical-in organoids. Using this advanced model, we demonstrated the expression and function of two novel ion channels, the Ca2+ activated Cl- channel Anoctamin 1 (ANO1) and the epithelial Na+ channel (ENaC), which were not considered in ductal cells yet. Finally, we showed that the available functional assays, such as forskolin-induced swelling, or intracellular Cl- measurement have improved dynamic range when performed with apical-out organoids. Taken together our data suggest that polarity-switched human pancreatic ductal organoids are suitable models to expand our toolset in basic and translational research.

Validation of the modified Alvarado score on patients attending A&E units with suspected appendicitis.

INTRODUCTION: The aim of our prospective study was to confirm validity and diagnostic accuracy of the modified Alvarado score, which was developed at the Department of Surgery, University of Szeged, on patients presenting with symptoms suggestive of acute appendicitis (right lower quadrant complaints) at the A&E department. PATIENT POPULATION, METHODS: 138 patients were included in our study between 01.01.2019 and 01.01.2020. For patients attending A&E, the first medic calculated and recorded the modified Alvarado score before surgical consultation. The consulting surgeon decided on further treatment without knowing the score. Validation of the score was based on the pathology report of the removed appendix (whether the operation was warranted, and if the score also supported indication for surgery), if there was readmission or surgery due to worsening symptoms after discharge from A&E. We also examined if there was any connection between the value of the Alvarado score and the severity of inflammation. Our aim was to prove that using modified Alvarado score at the A&E Units helps to reduce patient's waiting time and avoid unnecessary surgical consultations. Furthermore our study included measuring the diagnostic accuracy of the ultrasound examination (specificity, sensitivity). RESULTS: Based on the results, patients presenting at A&E had a mean modified Alvarado score of 6.5. Comparing the score to histological results showed that the specificity of the modified Alvarado score was 100%, and its sensitivity was 80.7%. Based on Spearman's rank correlation (0.796) and ROC analysis (AUC 0.968), the modified Alvarado score has an excellent predictive value in diagnosing acute appendicitis. When comparing the patients' waiting times with the use of modified Alvarado score and without it we found that there was a significant difference in group also in group under 4 points and in group over 7 points when using modified Alvarado score, so the diagnostic and therapeutic algorithm should be much quicker with the help of the score. We found a correlation between the severity of inflammation based on the Fisher's exact test. Rank correlation of the same question also showed a significant connection. All patients had an US examination during their diagnostic course, its sensitivity was 82.6%, specificity was 87%. Based on this, we can conclude that the predictive value of the imaging method is good. CONCLUSIONS: We can conclude according to our results that the predictive value of the modified score is excellent, and it can be safely applied by non-surgeons in urgent care in the differential diagnosis of acute appendicitis. The new score incorporates the results of an easily obtainable, ionising radiation free imaging method, the ultrasound, which was not included in previous scores. With the help of the new score, the number of unnecessary surgical referrals and waiting times for patients are reduced, excess examinations will become avoidable.

Predictive Potential of RNA Polymerase B (II) Subunit 1 (RPB1) Cytoplasmic Aggregation for Neoadjuvant Chemotherapy Failure.

We aimed to investigate the contribution of co-translational protein aggregation to the chemotherapy resistance of tumor cells. Increased co-translational protein aggregation reflects altered translation regulation that may have the potential to buffer transcription under genotoxic stress. As an indicator for such an event, we followed the cytoplasmic aggregation of RPB1, the aggregation-prone largest subunit of RNA polymerase II, in biopsy samples taken from patients with invasive carcinoma of no special type. RPB1 frequently aggregates co-translationally in the absence of proper HSP90 chaperone function or in ribosome mutant cells as revealed formerly in yeast. We found that cytoplasmic foci of RPB1 occur in larger sizes in tumors that showed no regression after therapy. Based on these results, we propose that monitoring the cytoplasmic aggregation of RPB1 may be suitable for determining-from biopsy samples taken before treatment-the effectiveness of neoadjuvant chemotherapy.

Bile acid- and ethanol-mediated activation of Orai1 damages pancreatic ductal secretion in acute pancreatitis.

Regardless of its aetiology, sustained intracellular Ca2+ overload is a well-known hallmark of acute pancreatitis (AP). Toxic Ca2+ elevation induces pancreatic ductal cell damage characterized by impaired ion and fluid secretion - essential to wash out the protein-rich fluid secreted by acinar cells while maintaining the alkaline intra-ductal pH under physiological conditions - and mitochondrial dysfunction. While prevention of ductal cell injury decreases the severity of AP, no specific drug target has yet been identified in the ductal cells. Although Orai1, a store-operated Ca2+ influx channel, is known to contribute to sustained Ca2+ overload in acinar cells, details concerning its expression and function in ductal cells are currently lacking. In this study, we demonstrate that functionally active Orai1 channels reside predominantly in the apical plasma membrane of pancreatic ductal cells. Selective CM5480-mediated Orai1 inhibition impairs Stim1-dependent extracellular Ca2+ influx evoked by bile acids or ethanol combined with non-oxidative ethanol metabolites. Furthermore, prevention of sustained extracellular Ca2+ influx protects ductal cell secretory function in vitro and decreases pancreatic ductal cell death. Finally, Orai1 inhibition partially restores and maintains proper exocrine pancreatic secretion in in vivo AP models. In conclusion, our results indicate that Orai1 inhibition prevents AP-related ductal cell function impairment and holds the potential of improving disease outcome. KEY POINTS: Sustained intracellular Ca2+ overload in pancreatic acinar and ductal cells is a hallmark of biliary and alcohol-induced acute pancreatitis, which leads to impaired ductal ion and fluid secretion. Orai1 is a plasma membrane Ca2+ channel that mediates extracellular Ca2+ influx upon endoplasmic reticulum Ca2+ depletion. Results showed that Orai1 is expressed on the luminal plasma membrane of the ductal cells and selective Orai1 inhibition impaired Stim1-dependent extracellular Ca2+ influx evoked by bile acids or ethanol combined with non-oxidative ethanol metabolites. The prevention of sustained extracellular Ca2+ influx protected ductal cell secretory functions in in vitro models and maintained exocrine pancreatic secretion in in vivo acute pancreatitis models. Orai1 inhibition prevents the bile acid- and alcohol-induced damage of the pancreatic ductal secretion and holds the potential of improving the outcome of acute pancreatitis.

Surgical outcome of percutaneous transhepatic gallbladder drainage in acute cholecystitis: Ten years' experience at a tertiary care centre.

BACKGROUND: Percutaneous transhepatic gallbladder drainage (PTGBD) plays an important role in the treatment of elderly patients and/or patients in poor health with acute cholecystitis (AC). The primary aim of this study is to determine how these factors influence the clinical outcome of PTGBD. Moreover, we assessed the timing and results of subsequent cholecystectomies. PATIENTS AND METHODS: We retrospectively examined the results of 162 patients undergoing PTGBD between 2010 and 2020 (male-female ratio: 51.23% vs. 48.77%; mean age: 71.43 ± 13.22 years). Patient's performance status and intervention outcomes were assessed with clinical success rates (CSR) and in-hospital mortality. The conversion rate (CR) of possible urgent or delayed, elective laparoscopic cholecystectomies (LC) after PTGBD were analysed. RESULTS: PTGBD was the definitive treatment in 42.18% of patients, while it was a bridging therapy prior to cholecystectomy (CCY) for the other patients. CSR was 87.97%, it was only 64.29% in grade III AC. In 9.87% of the cases, urgent LC was necessary after PTGBD, and its conversion rate was approximately equal to that of elective LC (18.18 vs. 17.46%, respectively, p = 0.2217). Overall, the post-PTGBD in-hospital mortality was 11.72%, while the same figure was 0% for grade I AC, 7.41% for grade II and 40.91% for grade III. Based on logistic regression analyses, in-hospital mortality (OR 6.07; CI 1.79-20.56), clinical progression (OR 7.62; CI 2.64-22.05) and the need for emergency CCY (OR 14.75; CI 3.07-70.81) were mostly determined by AC severity grade. CONCLUSION: PTGBD is an easy-to-perform intervention with promising clinical success rates in the treatment of acute cholecystitis. After PTGBD, the level of gallbladder inflammation played a decisive role in the course of AC. In a severe, grade III inflammation, we have to consider low CSR and high mortality.

The impact of EAES Fellowship Programme: a five-year review and evaluation.

BACKGROUND: The European Association of Endoscopic Surgery (EAES) fellowship programme was established in 2014, allowing nine surgeons annually to obtain experience and skills in minimally invasive surgery (MIS) from specialist centres across the Europe and United States. It aligns with the strategic focus of EAES Education and Training Committee on enabling Learning Mobility opportunities. To assess the impact of the programme, a survey was conducted aiming to evaluate the experience and impact of the programme and receive feedback for improvements. METHODS: A survey using a 5-point Likert scale was used to evaluate clinical, education and research experience. The impact on acquisition of new technical skills, change in clinical practice and ongoing collaboration with the host institute was assessed. The fellows selected between 2014 and 2018 were included. Ratings were analysed in percentage; thematic analysis was applied to the free-text feedbacks using qualitative analysis. RESULTS: All the fellows had good access to observing in operating theatres and 70.6% were able to assist. 91.2% participated in educational activities and 23.5% were able to contribute through teaching. 44.1% participated in research activities and 41.2% became an author/co-author of a publication from the host. 97.1% of fellows stated that their operative competency had increased, 94.3% gained new surgical skills and 85.7% was able to introduce new techniques in their hospitals. 74.29% agreed that the clinical experience led to a change in their practices. The most commonly suggested improvements were setting realistic target in clinical and research areas, increasing fellowship duration, and maximising theatre assisting opportunities. Nevertheless, 100% of fellows would recommend the fellowship to their peers. CONCLUSION: EAES fellowship programme has shown a positive impact on acquiring and adopting new MIS techniques. To further refine the programme, an individualised approach should be adopted to set achievable learning objectives in clinical skills, education and research.

Complete laparoscopic-transhiatal removal of duplex benign oesophageal tumour: case report and review of literature.

BACKGROUND: Leiomyoma is the most common benign oesophageal tumour. Half of all leiomyoma patients have oesophagus-associated complaints, such as dysphagia and epigastric pain, and the other 50% are asymptomatic with a diagnosis made on incidental discovery. Endoscopic ultrasonography is essential for an accurate preoperative workup and can enable guided-tissue acquisition for immunohistochemistry in certain cases. Smaller tumours are amenable to traditional and novel endoscopic removal in specialized centres, but some complex cases require surgical enucleation with a minimally invasive approach. CASE PRESENTATION: An asymptomatic 60-year-old woman was accidentally diagnosed with a bifocal oesophageal mass, which was discovered by chest computed tomography. We report a rare case of a duplicated lower-third oesophageal leiomyoma, which was completely removed via the laparoscopic transhiatal approach. The patient has recovered successfully from the surgery. She has been followed up for six months with a normal oesophagram, adequate oesophageal function and no complaints observed. Pathological examination confirmed the diagnosis of leiomyoma in both lesions. CONCLUSIONS: To the best of our knowledge, this is the first reported case of duplex oesophageal leiomyomas removed laparoscopically. Using the minimally invasive abdominal technique, the lower oesophagus can be mobilised to the mediastinum without pleura injury and offers a good alternative to the thoracoscopic approach in patients with possible intrathoracic difficulties. At experienced centres, laparoscopic transhiatal enucleation of lower oesophageal leiomyomas and other benign tumours with a combination of intraoperative oesophagoscopy is a safe, fast and effective operation.

Evaluation of the conversion rate as it relates to preoperative risk factors and surgeon experience: a retrospective study of 4013 patients undergoing elective laparoscopic cholecystectomy.

BACKGROUND: Our aim is to determine the relationships among patient demographics, patient history, surgical experience, and conversion rate (CR) during elective laparoscopic cholecystectomies (LCs). METHODS: We analyzed data from patients who underwent LC surgery between 2005 and 2014 based on patient charts and electronic documentation. CR (%) was evaluated in 4013 patients who underwent elective LC surgery. The relationships between certain predictive factors (patient demographics, endoscopic retrograde cholangiopancreatography (ERCP), acute cholecystitis (AC), abdominal surgery in the patient history, as well as surgical experience) and CR were examined by univariate analysis and logistic regression. RESULTS: In our sample (N = 4013), the CR was 4.2%. The CR was twice as frequent among males than among females (6.8 vs. 3.2%, p < 0.001), and the chance of conversion increased from 3.4 to 5.9% in patients older than 65 years. The detected CR was 8.8% in a group of patients who underwent previous ERCP (8.8 vs. 3.5%, p < 0.001). From the ERCP indications, most often, conversion was performed because of severe biliary tract obstruction (CR: 9.3%). LC had to be converted to open surgery after upper and lower abdominal surgeries in 18.8 and 4.8% cases, respectively. Both AC and ERCP in the patient history raised the CR (12.3%, p < 0.001 and 8.8%, p < 0.001). More surgical experience and high surgery volume were not associated with a lower CR prevalence. CONCLUSIONS: Patient demographics (male gender and age > 65 years), previous ERCP, and upper abdominal surgery or history of AC affected the likelihood of conversion. More surgical experience and high surgery volume were not associated with a lower CR prevalence.

Incarcerated gallbladder in inguinal hernia: a case report and literature review.

BACKGROUND: Treating hernias is one of the oldest challenges in surgery. The gallbladder as content in the case of abdominal hernias has only been reported in a few cases in the current literature. Cholecyst has only been described in the content of an inguinofemoral hernia in one case to date. CASE PRESENTATION: A 73-year-old female patient was admitted to the Emergency Department due to complaints in the right inguinal area, which had started 1 day earlier. The patient complained of cramp-like abdominal pain and nausea. Physical examination confirmed an apple-sized, irreducible hernia in the right inguinal region. Abdominal ultrasound confirmed an oedematous intestinal loop in a 70-mm-long hernial sac, with no circulation detected. Abdominal X-ray showed no signs of passage disorder. White blood cell count and C-reactive protein level were elevated, and hepatic enzymes were normal in the laboratory findings. Exploration was performed via an inguinal incision on the right side, an uncertain cystic structure was found in the hernial sac, and several small abnormal masses were palpated there. The abdominal cavity was explored from the middle midline laparotomy. During the exploration, the content of the hernial sac was found to be the fundus of the significantly ptotic, large gallbladder. Cholecystectomy and Bassini's repair of the inguinal hernia were performed safely. CONCLUSIONS: Following a review of the literature, it can be concluded that the finding of incarcerated gallbladder in the content of an inguinal hernia is a rare finding. No other similar emergency case and successful surgical intervention have been reported before.

Laparoscopic transperitoneal and retroperitoneal adrenalectomy: a 20-year, single-institution experience with an analysis of the learning curve and tumor size [lap transper and retroper adrenalectomy].

BACKGROUND: The superiority of laparoscopic transperitoneal (TP) versus retroperitoneal (RP) adrenalectomy is an ongoing debate. METHODS: Data from 163 patients (TP: n = 135; RP: n = 28) undergoing minimally invasive adrenalectomy were analyzed. Both operative [intraoperative blood loss, previous abdominal surgery, conversion rate, operative time and tumor size] and perioperative [BMI (body mass index), ASA (American Society of Anesthesiologists) score, time of hospitalization, time of oral intake, histology and postoperative complications] parameters were compared. Both the learning curve (LC) and tumor size were analyzed. RESULTS: We found significant differences in the mean operative time (p = 0.019) and rate of previous abdominal surgery (p = 0.038) in favor of TP. Significantly larger tumors were removed with TP (p = 0.018). Conversion rates showed no significant difference (p = 0.257). Also, no significant differences were noted for time of hospitalization, intraoperative blood loss and postoperative complications. In terms of the LC, we saw significant differences in previous abdominal surgery (p = 0.015), conversion rate (p = 0.011) and operative time (p = 0.023) in favor of TP. Large (LT) and extra-large tumors (ELT) were involved in 47 lesions (LT: 40 vs. ELT: 7), with a mean tumor size of 71.85 and 141.57 mm, respectively. Mean intraoperative blood loss was 64.47 ml vs. 71.85 ml, time of hospitalization was 5.10 vs. 4.57 days and mean operative time was 76.52 vs. 79.28 min for LT and ELT, respectively. CONCLUSION: A shorter operative time and lower conversion rate in favor of TP were noted during the learning curve. TP proved to be more effective in the removal of large-, extra-large and malignant lesions. The RP approach was feasible for smaller, benign lesions, with a more prolonged learning curve.

Evaluating the distribution of the locations of colorectal cancer after appendectomy and cholecystectomy.

BACKGROUNDS: The number of appendectomies and cholecystectomies performed is gradually increasing worldwide. An increasing incidence of colorectal cancer (CRC) after appendectomy and cholecystectomy has been reported, but the location of tumors in certain segments of the colon and rectum after appendectomy and cholecystectomy is still uncertain. We aimed to evaluate the distribution of the locations of colorectal cancer after appendectomy and/or cholecystectomy in patients who underwent CRC surgery. METHODS: We reviewed the medical records of patients who had undergone CRC surgery between 2015 and 2017 for the presence of previous appendectomy/cholecystectomy. Data were collected from the Colorectal Data Base of the University of Szeged, Department of Surgery. RESULTS: Surgery for CRC was performed in 640 patients during the study period. Data of 604 patients were analyzed. Appendectomy was performed in 100 patients (16.6%), cholecystectomy in 65 (10.8%), and both interventions in 18 (3%) before the CRC surgery. Out of those patients who underwent appendectomy alone, 92 (92%) had undergone appendectomy more than 10 years before the CRC surgery. Also in these 100 patients, the prevalence of right-sided colon cancer (CC) was 35% (n = 35), in comparison with the prevalence among the 504 other patients (20.4%, n = 103). The prevalence of right-sided CC among patients who underwent cholecystectomy alone was 36.9% (n = 24), in comparison with 21.2% (n = 114) of the 539 other patients. CONCLUSIONS: A significant left to right side shift in CRC was noted among patients who had previously undergone appendectomy/cholecystectomy. Because right-sided CC has a worse prognosis, the role of incidental appendectomy and routine cholecystectomy seems that need re-evaluation.

Adenocarcinoma arising from a foregut cyst of the diaphragm: importance of multimodality treatment: a case report.

BACKGROUND: Benign foregut cysts usually develop in the thorax most of all in the mediastinum. Rare cases involving various abdominal organs, such as liver, stomach or pancreas have been previously published, mostly occurring in the retroperitoneum. CASE PRESENTATION: We herein present an adenocarcinoma of a foregut cyst involving the left side of the diaphragm, left lower lobe of the lung, and left lobe of the liver, successfully removed through multivisceral resection. In between drug holidays, postoperative oncological treatment has been ongoing for nearly 4 years. In terms of chemotherapy, FOLFOX 4 regime, capacitabine monotherapy and later on next generation sequencing has been attempted, although the patient refused the later treatment option. Despite multimodality (combined surgical and oncological) treatment, local- and later on loco-regional recurrence has been detected on follow-up staging, influencing further chemotherapy regime. Taking both the fairly unknown type of the tumor and uncertain response rate to oncological therapy into account, prolonged tumor pace with fairly stable general patient state was reached throughout the course of the disease. CONCLUSION: Through surgical tumor resection, and postoperative chemotherapy the patient managed to maintain an acceptable quality of life without major symptoms during ongoing treatment. During our own case, with multiple organ involvement, multivisceral resection, with multimodality treatment had considerable effect in prolonging the lifespan of the patient.

[The reliability and validity of the Hungarian version of the Surgical Fear Questionnaire]. / A Sebészeti Beavatkozástól Való Félelem Kérdoív magyar nyelvu változatának reliabilitás- és validitásvizsgálata sebészeti beavatkozáson átesett páciensek körében.

INTRODUCTION: Interdisciplinary studies confirm that surgical fear experienced by patients can have a substantial effect on the outcome of the surgery and the healing process after surgery. AIM: The aim of this study was to assess the reliability and validity of the Hungarian version of the Surgical Fear Questionnaire in cancer patients. METHOD: 149 patients were assessed using the Spielberger Anxiety Inventory, the Beck Depression Inventory, the Visual Analogue Scale and the Surgical Fear Questionnaire. RESULTS: The scale showed excellent internal consistency (Cronbach-alfa = 0.878; 0.885). The Surgical Fear Questionnaire scores moderately correlated with anxiety, depression and anticipated pain after surgery. CONCLUSION: The reliability and validity of the Hungarian version of the Surgical Fear Questionnaire in the sample were excellent. The questionnaire turned out to be a useful psychometric tool in the measurement of surgical fear. Orv Hetil. 2018; 159(47): 1988-1993.

[Changes in the clinicopathological features of surgically treated lung cancer around the millennium]. / A mutétileg kezelt tüdorák klinikopatológiai jellemzoinek változása az ezredfordulónkon.

INTRODUCTION: Lung cancer is the most common malignant tumor in Europe and Hungary. In 2010, 10 557 new cases were registered in Hungary; 80-85% of these cases were associated with smoking. AIM: In our work we analyzed the data of lung cancer patients of the last 15 years retrospectively. METHOD: We examined the demographic characteristics, the histological type, the stage of the lung cancer, the type of the surgical procedure used, other supplemental treatment and survival retrospectively. RESULTS: Lung cancer has occurred 50 per cent more often among females in the last decade. This growth is due to the increase of adenocarcinoma cases. Thanks to the improving diagnostic modalities and the routine follow-up of oncological patients, the number of I/A cases has been doubled recently and the preoperative staging and physical condition check-up have become more accurate. Neoadjuvant treatment has been introduced, the proportion of sublobar resections has risen, the ratio of pneumonectomy and sleeve lobectomy has become equal, so many previously unresectable cases turned to be resectable and the tolerance of adjuvant therapy has also improved. Videothoracoscopic lobectomy has become an everyday practice, leading to a decrease in the operative stress on patients. CONCLUSION: In spite of this development, the five-year survival has not changed significantly, staying around 50%. Orv Hetil. 2018; 159(10): 391-396.

[Perioperative factors influencing the tolerability of chemotherapy after lung lobe resection]. / Tüdolebeny-eltávolítást követo kemoterápia tolerabilitását befolyásoló perioperatív tényezok.

INTRODUCTION: Lung cancer is the leading cause of malignancy-related deaths in Hungary, involving complex surgical and oncological treatment. AIM: Factors influencing the tolerability of complete/planned and incomplete postoperative chemotherapy after surgery were analyzed. METHOD: During a 6-year period (January 1, 2011-December 31, 2016), data of 72 patients operated with lung cancer (adenocarcinoma and squamous cell carcinoma), receiving complete (4 cycles) and incomplete (<4 cycles) postoperative chemotherapy were analyzed. The following factors among the two groups [complete: n = 53; incomplete: n = 19] were analyzed: gender, mean age, body mass index, Malnutrition Universal Screening Tool, Charlson Comorbidity Index, second malignant tumor, atrial fibrillation, Forced Expiratory Volume 1 sec, Performance Status, open/Video-Assisted Thoracic Surgery (VATS) lobectomy, duration of surgery, postoperative fever, need for transfusion, prolonged air leak, redo surgery, histology, tumor stage. RESULTS: The rate of complete postoperative cycles obtained from logistic regression analysis, were substantially higher after VATS lobectomies [n = 26 (83.87%)] compared to open procedures [n = 27 (65.85%)]; (p = 0.092; OR = 0.356), without significance. Multivariate analysis (open/VATS lobectomy, upper/middle-lower lobe resection, diabetes, prolonged air leak, postoperative fever) showed significantly increased successful uptake of complete cycles after VATS (p = 0.0495), while upper/middle lobe resections (p = 0.0678) and the lack of diabetes (p = 0.0971) notably increased the number of complete cycles, without significance. CONCLUSION: Twenty-six percent of patients were unable to receive complete planned postoperative chemotherapy. VATS lobectomy patients received significantly higher number of complete cycles of postoperative chemotherapy. Diabetes and lower lobe lobectomies had a negative effect on the tolerability of postoperative chemotherapy. Orv Hetil. 2018; 159(19): 748-755.

[Treatment of osteomyelitis in diabetes mellitus. Case report]. / Diabetes mellitus talaján kialakult osteomyelitis kezelése.

The authors summarize the medical history of a patient with impaired healing of a wound in the sole of foot. The 63-year-old male patient had a second-degree burn in the sole of the left foot as he stepped on the hot concrete after taking off his slipper. On admission to our department, local wound management had already been started, his wound showed no healing tendency. Bilateral X-ray was performed of his left leg, osteomyelitis was not confirmed, soft tissue drainage was applied, and bacterial culture from the wound confirmed methicillin-resistant Staphylococcus aureus infection. After soaking the leg in water, phlegmon developed on the dorsal part of the foot and the patient had septic fever. X-ray was repeated, and osteomyelitis was confirmed. Enucleation of the hallux of the left foot and metatarsal resection were performed. Wound dressing was exchanged and wound toilette was applied daily, insulin therapy was modified after consultation with a diabetologist. 7 months after the surgery, the wound was completely healed, carbohydrate metabolism of the patient was controlled. Our case draws attention to the importance of informing the patients of potential complications - in this case of the diabetic foot and its proper care. Treatment of ulcer of the lower leg requires multidisciplinary care, which means that the diabetologist and the surgeon has to cooperate in the care of these patients, carbohydrate metabolism should be balanced and regular wound care is necessary.

What contributes to long-term quality of life in breast cancer patients who are undergoing surgery? Results of a multidimensional study.

PURPOSE: This study aims to examine the key determinants of long-term quality of life in breast cancer patients who are undergoing surgery using a multidimensional approach and taking into account preoperative and post-operative psychological characteristics such as anxiety, depression, posttraumatic growth, body image, and physical activity as well as medical parameters. METHODS: The study involved 63 breast cancer patients from the Department of Surgery at the University of Szeged. Assessments occurred 1 day before surgery as well as 3 days and 18 months after surgery using the Spielberger State and Trait Anxiety Inventory (STAI), Beck's Depression Inventory (BDI), Functional Assessment of Cancer Therapy-Breast Cancer Scale (FACT-B), Posttraumatic Growth Inventory (PTGI) and Breast Impact of Treatment Scale (BITS). Data relating to physical activity, medical parameters and sociodemographic characteristics were also collected. RESULTS: The level of depression did not change over time. State anxiety decreased 18 months after the surgery compared to before the surgery; however, there was a greater decrease immediately after the surgery and then anxiety increased again 18 months later. Trait anxiety was associated with quality of life, posttraumatic growth and body image. Posttraumatic growth and the level of depression were found to be possible contributing factors to the increase in long-term quality of life. CONCLUSIONS: The results show that the timely detection and proper management of psychological distress and the enhancement of posttraumatic growth are of great value, as they might be important contributing factors to long-term quality of life in breast cancer patients.

[Changes in carbohydrate metabolism after kidney transplantation and their effects on cardiovascular risk]. / Vesetranszplantáció utáni szénhidrátanyagcsere-változások és annak hatásai a cardiovascularis rizikóra.

INTRODUCTION: Cardiovascular disease is the major cause of deaths after transplantation, with diabetes mellitus being the main risk factor in development. AIM: The aim of our study was to assess the prevalence of new onset diabetes mellitus in connection with the cardiovascular risk predicted by the HEART Score. METHOD: 44 patients were involved in our study; after overview of baseline data, OGTT was performed, followed by patient classification into the following groups: normal, impaired fasting glucose/impaired glucose tolerance, and new onset diabetes mellitus. Insulin resistance and kidney function were also assessed. RESULTS: Concerning baseline data, cold ischemic time (p = 0.016), body weight (p = 0.035), BMI (p = 0.025), and HbA1C (p = 0.0024) proved to be significantly different between normal and diabetic patients. Significant difference was found based on HOMA IR between the two groups 1.69±0.51 vs 6.46±1.42; p = 0.0017). Based on the HEART Score, patients with new onset diabetes mellitus were put into Group 3, which also reflects the risk which diabetes carries for the development of cardiovascular diseases. CONCLUSION: Cardiovascular risk can be decreased with increased allograft survival by early diagnosis and management of diabetes. Orv Hetil. 2017; 158(38): 1512-1516.

[Removal of giant adrenal tumors using the laparoscopic transperitoneal technique. A report of three successful cases]. / Óriás mellékvesetumorok eltávolítása laparoszkópos transperitonealis technikával három sikeres eset kapcsán.

With the development of laparoscopic adrenalectomy, indications for resection gradually span from small and benign to bigger and even malignant lesions. We studied the results of laparoscopic adrenalectomy for giant (>10 cm) adrenal tumors in three cases. Three patients (2 female, 1 male, mean age 49.33 years, BMI 31) underwent laparoscopic transperitoneal adrenalectomy due to giant (>10 cm) adrenal lesions with a limited size Pfannenstiel incision. Mean operative time was 126.66 minutes, with a mean intraoperative blood loss of 150 ml. Final histology confirmed adrenocortical carcinoma in two cases, and neurofibroma in one case. Mean hospital stay was 4 days, without perioperative complications. R0 resection was carried out in all cases. During a mean follow-up period of 24 months no local or distant metastasis occurred. Under appropriate conditions adrenalectomy performed by the laparoscopic transperitoneal technique for giant malignant tumors proved to be a safe method fulfilling oncological requirements.

[Tension-type headache in ulcerative colitis]. / Tenziós típusú fejfájás és colitis ulcerosa.

BACKGROUND AND PURPOSE: Tension-type headache is a very common disease with a high socio-economic impact as its lifetime prevalence is 30-78% in the general population. The incidence of inflammatory bowel diseases is continuously rising. Limited data are accessible on quality of life in patients with surgically treated ulcerative colitis. The aim of our study is to examine quality of life, concerning headache, among patients who had undergone surgery due to ulcerative colitis. METHODS: Between 1 January 2005 and 1 March 2016, surgery was performed due to ulcerative colitis in 75 patients. During this retrospective analysis the average duration of the follow-up was 46 (1-124) months. The pre-sence of headache was evaluated by the use of Brief Illness Perception and Headache Questionnaires. RESULTS: Among the primary headache disorders (n=27), tension-type headache occurred in 19 (70.4%) cases, and 8 (29.6%) patients had migraine (without aura). Among tension-type headache cases 17 (89.5%) patients experienced episodic form and 2 (10.5%) suffered from chronic form. Patients with headache had obtained a significantly higher score on Brief Illness Perception Questionnaire. CONCLUSION: According to our study tension-type headache is common among patients with ulcerative colitis. This observation raises the question whether stress plays role in the pathogenesis of both diseases, which influences and worsens considerably quality of life. Neurological examination, psychological and psychiatric guidance are worth considering in patients with ulcerative colitis.
