Performance of Ultrasonography in the Diagnosis of Acute Colonic Diverticulitis.

OBJECTIVES: Computed tomography is regarded as the reference-standard imaging modality for the assessment of acute left-sided colonic diverticulitis (ALCD). However, its utility may be impaired by cost issues, limited availability, radiation exposure, and contrast-related adverse effects. Ultrasonography is increasingly advocated as an alternative technique for evaluating ALCD, although there is variation regarding its accuracy in disease diagnosis and staging and in determining alternative diagnoses. The aim of this study was to assess the performance of ultrasonography in diagnosing ALCD, differentiating complicated from non-complicated disease and defining alternative diseases related to left lower quadrant pain. METHODS: Within a 2-year period, all consecutive adult patients with clinically suspected ALCD and available abdominal computed tomography were prospectively evaluated and planned to undergo an abdominal ultrasonographic examination, tailored to the assessment of left lower quadrant. Computed tomography (CT) was regarded as the reference standard. RESULTS: A total of 132 patients (60 males, 72 females; mean age: 61.3 ± 11 years) were included. The sensitivity, specificity, and area under curve of ultrasonography for diagnosing ALCD were 88.6, 84.9, and 86.8%, with positive and negative predictive values of 89.7 and 83.3%, respectively. The method had sensitivity, specificity, and area under curve of 77.8, 100, and 88.9%, respectively, for defining complicated disease. The area under the curve for the identification of alternative diseases in patients with left lower quadrant pain was 90.9%. CONCLUSIONS: Ultrasonography has high diagnostic accuracy for diagnosing ALCD, differentiating complicated from non-complicated disease and establishing alternative diagnoses related to left lower quadrant pain. A low threshold to get a CT should be maintained as not to miss cases that may mimic ALCD.

Performance of thoracic ultrasonography compared with chest radiography for the detection of rib fractures using computed tomography as a reference standard.

OBJECTIVE: Although there is growing evidence that ultrasonography is superior to X-ray for rib fractures' detection, X-ray is still indicated as the most appropriate method. This has partially been attributed to a lack of studies using an appropriate reference modality. We aimed to compare the diagnostic accuracy of ultrasonography and X-ray in the detection of rib fractures, considering CT as the reference standard. MATERIALS AND METHODS: Within a 2.5-year period, all consecutive patients with clinically suspected rib fracture(s) following blunt chest trauma and available posteroanterior/anteroposterior X-ray and thoracic CT were prospectively studied and planned to undergo thoracic ultrasonography, by a single operator. All imaging examinations were evaluated for cortical rib fracture(s), and their location was recorded. The cartilaginous rib portions were not assessed. CTs and X-rays were evaluated retrospectively. Concomitant thoracic/extra-thoracic injuries were assessed on CT. Comparisons were performed with the Mann-Whitney U test and Fisher's exact test. RESULTS: Fifty-nine patients (32 males, 27 females; mean age, 53.1 ± 16.6 years) were included. CT, ultrasonography, and X-ray (40 posteroanterior/19 anteroposterior views) diagnosed 136/122/42 rib fractures in 56/54/27 patients, respectively. Ultrasonography and X-ray had sensitivity of 100%/40% and specificity of 89.7%/30.9% for rib fractures' detection. Ultrasound accuracy was 94.9% compared to 35.4% for X-rays (P < .001) in detecting individual rib fractures. Most fractures involved the 4th-9th ribs. Upper rib fractures were most commonly overlooked on ultrasonography. Thoracic cage/spine fractures and haemothorax represented the most common concomitant injuries. CONCLUSION: Ultrasonography appeared to be superior to X-ray for the detection of rib fractures with regard to a reference CT.

Comparative activities of ampicillin and teicoplanin against Enterococcus faecalis isolates.

BACKGROUND: Enterococcus faecalis remains one of the most common pathogens causing infection in surgical patients. Our goal was to evaluate the antibiotic resistance of E. faecalis, causing infections in a surgical clinic, against two antibacterial drugs, ampicillin and teicoplanin. One commonly administered in the past for such infections, ampicillin, and another newer, teicoplanin, which demonstrated exceptionally good efficacy. METHODS: Data from 1882 isolates were retrieved from the microbiology department database during two 5-year periods. Standard biochemical methods were employed for the identification of the isolates. The prevalence of E. faecalis among patients with clinical evidence of infection in a surgical oncology ward was assessed. Confidence interval (CI) as well as standard error (SE) were calculated. Moreover, the annual incidence of E. faecalis infections in this surgical ward was recorded. The susceptibility of E. faecalis to ampicillin and teicoplanin was studied and compared using Fisher's exact test. RESULTS AND CONCLUSION: Results showed that the incidence of E. faecalis infections in the surgical clinic was increasing. Ampicillin, in the later year period, was not statistically different from teicoplanin in treating E. faecalis infections. Consequently, ampicillin seems currently to be an effective antibiotic against such infections that could be used as empiric therapy.

A feasibility study of circulating melanoma cells in the perioperative context of hyperthermic isolated limb perfusion (HILP) in 20 patients.

INTRODUCTION: Hyperthermic Ιsolated Limb Perfusion using melphalan and TNFα (TM-HILP) is a regional chemotherapy method for advanced melanoma. PURPOSE: To explore the feasibility of the study of Circulating Melanoma Cells (CMCs) in the context of acute physiological changes induced by TM-HILP and their association with oncological outcomes. METHODS: The study included 20 patients undergoing TM-HILP for unresectable in-transit melanoma of the limbs, stage III(B/C/D). CMCs in the peripheral blood were analyzed at 5-time points from the preoperative day until day 7 from surgery using the following biomarkers: MITF, Tyrosinase mRNA, Melan-A and S100b, through quantitative RT-PCR. RESULTS: No CMCs according to Tyrosinase and Melan-A biomarkers were found in any sample. Friedman test showed significant alterations perioperatively for MITF (p < .001) and S100b (p = .001). Pairwise tests showed a significant increase of MITF levels on postoperative day 7 compared with postoperative day 1, intraoperative and preoperative levels (p < .05). Pairwise tests for S100b showed a significant difference between intraoperative sample and postoperative day 7 (p < .0001). Patients who experienced a complete response to TM-HILP (n = 12) had higher mean levels of MITF and the difference was significant at the time point immediately after the operation (0.29 ± 0.27 vs. 0.06 ± 0.06, p = .014) and on postoperative day 1 (1.48 ± 2.24 vs. 0.41 ± 0.65, p = .046). There was no association of MITF or S100b levels with 4-year disease specific survival. CONCLUSION: TM-HILP is associated with increased levels of CMCs, but there was no association of this increase with survival. Patients with complete response to HILP demonstrate higher values of MITF shortly after the operation.

Glycosylation Modulates Plasma Membrane Trafficking of CD24 in Breast Cancer Cells.

In breast cancer, expression of Cluster of Differentiation 24 (CD24), a small GPI-anchored glycoprotein at the cell periphery, is associated with metastasis and immune escape, while its absence is associated with tumor-initiating capacity. Since the mechanism of CD24 sorting is unknown, we investigated the role of glycosylation in the subcellular localization of CD24. Expression and localization of wild type N36- and/or N52-mutated CD24 were analyzed using immunofluorescence in luminal (MCF-7) and basal B (MDA-MB-231 and Hs578T) breast cancer cells lines, as well as HEK293T cells. Endogenous and exogenously expressed wild type and mutated CD24 were found localized at the plasma membrane and the cytoplasm, but not the nucleoplasm. The cell lines showed different kinetics for the sorting of CD24 through the secretory/endocytic pathway. N-glycosylation, especially at N52, and its processing in the Golgi were critical for the sorting and expression of CD24 at the plasma membrane of HEK293T and basal B type cells, but not of MCF-7 cells. In conclusion, our study highlights the contribution of N-glycosylation for the subcellular localization of CD24. Aberrant N-glycosylation at N52 of CD24 could account for the lack of CD24 expression at the cell surface of basal B breast cancer cells.

The evolving management of small bowel adenocarcinoma.

BACKGROUND: Small bowel adenocarcinoma (SBA) is rare despite the fact that the small bowel represents the longest part and has the largest surface of all alimentary tract sections. Its incidence is 50-fold lower than that of colorectal carcinoma. It is often diagnosed at an advanced stage due to atypical and late symptoms, its low index of suspicion, difficult endoscopic access and poor detection by radiological imaging, resulting in impaired outcome. Due to its rarity and being molecularly a unique intestinal cancer, data regarding its optimal management are relatively sparse. MATERIAL AND METHODS: A PubMed search was performed to identify relevant manuscripts that were recently published. Emerging data regarding the pathogenesis, the diagnosis and the treatment of SBA that resulted from recent research are discussed in this comprehensive review. RESULTS: Genomic analysis has demonstrated that SBA is a molecularly unique intestinal cancer. Double balloon enteroscopy and capsule endoscopy are novel techniques which may result in earlier diagnosis and consequently in improvement of the generally poor prognosis. For clinically localized disease, the quality of surgery has recently been defined, with removal of at least 8-10 lymph nodes correlating with improved prognosis. Moreover, adjuvant chemotherapy seems to improve outcome of stage III disease. The combination of a fluoropyrimidine and oxaliplatin appears to be the most effective systemic chemotherapy for disseminated disease. Genomic profiling can identify potentially targetable genomic alterations in a significant proportion of SBA patients. The role of administration of targeted agents or immune checkpoint inhibitors is still unknown and subject of ongoing clinical trials. In the common case of peritoneal metastases, recent studies have shown that cytoreductive surgery and intraoperative hyperthermic intraperitoneal chemotherapy may be an attractive treatment option in selected patients. CONCLUSIONS: SBA is a rare and unique malignancy, whose diagnostic approach and treatment are evolving, resulting in improved outcome.

The value of the Modified Early Warning Score for unplanned Intensive Care Unit admissions of patients treated in hospital general wards.

AIM: To determine the value of the Modified Early Warning Score (MEWS) for general ward patients and its potential use as an alarm tool for ward nurses. METHODS: A combined prospective-retrospective observational study was conducted with 153 patients in a university hospital (2013-2014). All patients were admitted to the intensive care unit (ICU) from general wards. Parameters retrospectively studied were 5 MEWS values at 4 hourly intervals, up to 20 hours before ICU admission. Parameters prospectively studied were ICU length of stay, ICU mortality, and mortality after ICU discharge. RESULTS: Most frequent severe adverse events were acute respiratory failure (39.9%) and septic shock (20.3%). Modified Early Warning Score increased gradually during the last 20 hours, and most patients remained in the wards, above a cut-off point ≥7 recorded at 4 hours before admission. Significant associations between latest MEWS score and ICU mortality and ICU length of stay were found. MEWS score≥ 7 hours before admission was highly associated with increased ICU and hospital mortality. CONCLUSION: Patient deterioration in general wards can result in severe adverse events. Modified Early Warning Score is a strong predictor of outcome and may be used as a monitoring tool for potentially avoidable deaths and unplanned admissions to ICU.

Treatment of peritoneal metastases from small bowel adenocarcinoma.

BACKGROUND/PURPOSE: Peritoneal metastases (PM) affect approximately one third of patients with metastatic small bowel adenocarcinoma (SBA). Treatment options are (1) systemic therapy ± palliative surgery and (2) cytoreductive surgery with intraperitoneal chemotherapy (CRS + IPC). Due to scarce evidence, PM from SBA represents a therapeutic challenge. This narrative review summarised and discussed the evidence that investigated available treatment options. METHODS: Studies were discussed if they investigated first line systemic therapy for advanced SBA or CRS + IPC for PM from SBA. Extracted outcomes were objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), disease-free survival (DFS), overall survival (OS), and grade III-V toxicity/morbidity. RESULTS: Eighteen studies (15 observational, 3 phase II) that investigated systemic therapy and six observational studies that investigated CRS + IPC were reviewed. In studies that investigated systemic therapy, ORR, DCR, median PFS, median OS, and grade III-V toxicity ranged from 6% to 50%, 50% to 90%, 3 to 11 months, 8 to 20 months, and 10% to 68%, respectively. Fluoropyrimidine-oxaliplatin revealed favourable survival outcomes compared to fluoropyrimidine-irinotecan, fluoropyrimidine-cisplatin, fluoropyrimidine monotherapy, and other regimens. In studies that investigated CRS + IPC, median DFS, median OS, and grade III-V morbidity ranged from 10 to 12 months, 16 to 47 months, and 12% to 35%, respectively. CONCLUSION: Based on available evidence, fluoropyrimidine-oxaliplatin should be regarded as optimal first line systemic treatment. In selected patients, CRS + IPC appears safe and may be more effective than systemic therapy as single treatment. Future studies should evaluate survival and morbidity of CRS + IPC in larger cohorts, as well as the value of chemotherapy with targeted agents in metastatic SBA with subgroup analysis for PM from SBA.

Anthropometric Analysis of the Face.

BACKGROUND: Facial anthropometric analysis is essential for planning cosmetic and reconstructive facial surgery, but has not been available in detail for modern Greeks. In this study, multiple measurements of the face were performed on young Greek males and females to provide a complete facial anthropometric profile of this population and to compare its facial morphology with that of North American Caucasians. MATERIALS AND METHODS: Thirty-one direct facial anthropometric measurements were obtained from 152 Greek students. Moreover, the prevalence of the various face types was determined. The resulting data were compared with those published regarding North American Caucasians. RESULTS: A complete set of average anthropometric data was obtained for each sex. Greek males, when compared to Greek females, were found to have statistically significantly longer foreheads as well as greater values in morphologic face height, mandible width, maxillary surface arc distance, and mandibular surface arc distance. In both sexes, the most common face types were mesoprosop, leptoprosop, and hyperleptoprosop. Greek males had significantly wider faces and mandibles than the North American Caucasian males, whereas Greek females had only significantly wider mandibles than their North American counterparts. CONCLUSIONS: Differences of statistical significance were noted in the head and face regions among sexes as well as among Greek and North American Caucasians. With the establishment of facial norms for Greek adults, this study contributes to the preoperative planning as well as postoperative evaluation of Greek patients that are, respectively, scheduled for or are to be subjected to facial reconstructive and aesthetic surgery.

Lipomatous tumours of the head and neck: a spectrum of biological behaviour.

Lipomatous tumours are rare in the head and neck region. Their biological behaviour varies greatly, from absolutely benign to histologically benign but locally infiltrative and, finally, invasive with metastatic potential. Each lipomatous tumour has to be treated accordingly. It is of paramount importance before eventual surgery is planned to perform adequate imaging, diagnostic biopsy and careful assessment. Only in small (<5 cm), superficial soft tissue tumours or when magnetic resonance imaging has demonstrated specific features of lipoma, may diagnostic biopsy be omitted. In these cases, expectant management or simple excision is appropriate. Adequate preoperative diagnosis is important to assure adequate tumour control as well as optimal functional and cosmetic outcome. The major problem in the treatment of lipomatous tumours of the head and neck region is the presence of nearby delicate structures. Especially, wide surgical excision of liposarcomas may be hindered by anatomic constraints and may result in impaired functional and cosmetic outcome. Neoadjuvant radiotherapy and specific systemic chemotherapy may be helpful in the treatment of liposarcoma, especially when unresectable or when primary surgery is expected to result in poor oncological, functional or cosmetic outcome. Greater emphasis placed on the underlying biology of individual sarcoma subtypes, development and evaluation of novel therapies and greater specificity in the selection of chemotherapy agents based on activity in individual histological subtypes are expected to lead to improved efficacy of systemic treatment.

Optimal drugs for HIPEC in different tumors.

Although there is adequate evidence to support treatment of primary and secondary peritoneal surface malignancies with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC), the latter procedure is still far from standardized and optimization of its aspects may be warranted. Significant variations remain in HIPEC procedures and include also the drug choice. In this manuscript the characteristics of the optimal HIPEC drug will be discussed. Subsequently, the drug choice for HIPEC treatment of different peritoneal surface malignancies will be briefly analyzed. Prospective randomized trials are warranted to determine which drug is the most effective for HIPEC in each type of peritoneal surface malignancy. In the future, it would be of major significance when the choice of the most optimal drug in HIPEC may be tailored to the patient's individual tumor by adequate drug sensitivity testing of the tumor cells.

Management of penile tumours during the Byzantine period.

While conventional treatment of penile cancer consists of total penile amputation and bilateral lymphadenectomy, recently a more conservative strategy comprising penile-preserving surgery and selective lymphadenectomy has been applied in order to preserve the penis and to minimize unnecessary inguinal lymphadenectomy. A thorough literature survey was performed to see what was already known of the surgical treatment of penile tumours in ancient times. In the Byzantine period, surgery appeared to have been highly developed, as one may conclude from the surgical material included mainly in the works of Oribasius of Pergamus and Paul of Aegina. Being aware of cancer, they described in their medical encyclopaedias malignant and benign tumours of the prepuce and glans penis, as well as their surgical and non-surgical management. After local excision of malignant tumours, they strongly recommended burning to prevent relapse, whereas they discouraged simultaneous removal of external and internal preputial lesions, because of the risk of perforation of the prepuce. These surprisingly detailed descriptions prove that Byzantine surgery had reached a higher level than commonly supposed. Penile-preserving treatment, which has recently become the therapeutic strategy of choice, was already accomplished in ancient times by using adjuvant thermal or chemical burning after local tumour excision.

Large presacral tailgut cyst with a carcinoid tumor in a male: report of a case.

Tailgut cysts are developmental hamartomas found in the presacral space. They are usually detected incidentally during physical examinations or imaging studies. However, they may cause symptoms due to compression of nearby organs. Due to their potential malignant transformation, surgical resection is warranted, while routine biopsy is considered controversial because of the concern about infection of the tailgut cyst and needle-track implantation of malignant cells. The co-existence of a carcinoid in a tailgut cyst is extremely rare. Only 16 cases have been reported previously, the vast majority of which were found in females. We herein present the case of a carcinoid in a tailgut cyst found in a male patient, discuss the potential pathogenesis of tailgut carcinoids, and underline the fact that their previous consideration of the condition as a female-restricted entity should be rejected.

Cocaine-Induced Chronic Bowel Ischemia Manifesting As Small Bowel Obstruction.

Cocaine represents one of the most frequently used recreational drugs worldwide. Cocaine-related disorders mostly affect the nervous and cardiovascular system, although gastrointestinal complications are not negligible and sometimes life-threatening. The most common gastrointestinal manifestations of cocaine abuse are ulceration, infarction, perforation, ischemic enterocolitis, and rarely hemorrhage, with mesenteric ischemia being the underlying pathophysiological mechanism. Herein, we report a rare case of cocaine-induced small bowel obstruction in a young female patient, caused by chronic mesenteric ischemia and excessive intestinal wall fibrosis.

Postoperative Bowel Obstruction as a Rare Complication of an Abdominal Drain.

Although routine intra-abdominal drain insertion following surgery represents a common practice worldwide, its utility has been questioned during the last decades. Several comparative studies have failed to document significant benefits from routine draining, and drain insertion has been correlated with various complications as well. Drain-related complications include, but are not limited, to infection, bleeding, and tissue erosion. Herein, we present the case of a 32-year-old patient with perforated peptic ulcer and purulent peritonitis, whose postoperative course was complicated by early mechanical bowel obstruction due to an abdominal drain. A high level of clinical suspicion, along with accurate imaging diagnosis, dictated prompt removal of the drain, which resulted in immediate resolution of the patient's symptoms. We aim to increase the clinical awareness of this rare complication related to intra-abdominal drain utilization with this report.

A combined opposite targeting of p110δ PI3K and RhoA abrogates skin cancer.

Malignant melanoma is the most aggressive and deadly skin cancer with an increasing incidence worldwide whereas SCC is the second most common non-melanoma human skin cancer with limited treatment options. Here we show that the development and metastasis of melanoma and SCC cancers can be blocked by a combined opposite targeting of RhoA and p110δ PI3K. We found that a targeted induction of RhoA activity into tumours by deletion of p190RhoGAP-a potent inhibitor of RhoA GTPase-in tumour cells together with adoptive macrophages transfer from δD910A/D910A mice in mice bearing tumours with active RhoA abrogated growth progression of melanoma and SCC tumours. Τhe efficacy of this combined treatment is the same in tumours lacking activating mutations in BRAF and in tumours harbouring the most frequent BRAF(V600E) mutation. Furthermore, the efficiency of this combined treatment is associated with decreased ATX expression in tumour cells and tumour stroma bypassing a positive feedback expression of ATX induced by direct ATX pharmacological inactivation. Together, our findings highlight the importance of targeting cancer cells and macrophages for skin cancer therapy, emerge a reverse link between ATX and RhoA and illustrate the benefit of p110δ PI3K inhibition as a combinatorial regimen for the treatment of skin cancers.

Alterations of global gastrointestinal motility after sleeve gastrectomy: a prospective study.

OBJECTIVES: To evaluate the role of sleeve gastrectomy (SG) in gastrointestinal motility. BACKGROUND: SG is a widely used bariatric operation leading to weight loss and early improvement of patient's metabolic profile. Current data indicate faster postoperative gastric emptying, but detailed studies on alterations in small bowel motility are missing. DESIGN: We evaluated 21 morbidly obese patients who underwent laparoscopic SG before and 4 months after the procedure. After consumption of a semisolid radiolabeled meal, their gastric and intestinal transit times were studied with a gamma camera. Particularly the times of 10% gastric emptying, 50% gastric emptying, maximal intestinal filling, 10% terminal ileum filling, duodenal to terminal ileum transit, cecal filling initiation, and ileocecal valve transit (T ICVt) were studied pre- and postoperatively. RESULTS: Ten percent gastric emptying and 50% gastric emptying were decreased postoperatively as well as maximal intestinal filling, indicating faster gastric emptying and intestinal filling. Duodenal to terminal ileum transit and 10% terminal ileum filling also decreased as small bowel transit time accelerated and the meal reached the terminal ileum more rapidly. Contrary opening of the ileocecal valve and food transit through it were delayed, with postoperative increase in cecal filling initiation and T ICVt, respectively. CONCLUSIONS: SG accelerates gastric emptying and small bowel transit of semisolids. In addition, it delays the initiation of cecal filling and T ICVt. This early and prolonged contact of food with the distal small bowel mucosa may explain the metabolic effects of SG occurring before substantial weight loss.

A giant pregnancy-associated intra-abdominal desmoid tumour: not necessarily a contraindication for subsequent pregnancy.

Desmoid tumours are rare mesenchymal tumours, often locally invasive and characteristically associated with a high local recurrence rate after resection. A potential aetiological role for female hormones is indicated. Pregnancy-associated desmoid tumours are almost exclusively located in the abdominal wall. An essential issue is how to counsel women who have had a pregnancy-associated desmoid tumour and subsequently wish to bear a child. A considerably rare case of a patient with a resection of a giant pregnancy-associated, 33 cm in diameter, intra-abdominal desmoid tumour is presented. After a subsequent pregnancy, the patient delivered healthy twins 26 months later. Fifty-four months after treatment, there are no signs of recurrent or second desmoid tumour. Although rarely located in the abdomen, pregnancy-associated desmoid tumours should be included in the differential diagnosis of intra-abdominal tumours detected during or shortly after pregnancy. Based on this case and a few others reported in the literature, subsequent pregnancy does not necessarily seem to be a risk factor for recurrent or new disease.

Co-existence of intramuscular spindle cell lipoma with an intramuscular ordinary lipoma:report of a case.

Spindle cell lipoma is a relatively rare adipocytic neoplasm, which usually occurs in the posterior neck, shoulder or upper back of male patients aged 45-65 years. We report here an unusual coexistence of ordinary and spindle cell lipoma. The patient presented with a painless mass in the area of the right scapula. Imaging was suggestive of a lipomatous mass, possibly liposarcoma. Histological examination revealed the concurrent existence of an intramuscular spindle cell lipoma and an ordinary lipoma. In the literature there are only fourteen cases of intramuscular spindle cell lipoma and only in four cases there was a coexisting mature lipoma. As exclusion of malignancy remains clinicians main concern,diagnosis and treatment of deep seated lipomatous tumors remains challenging.

A Six-Year Retrospective Study of Microbiological Characteristics and Antimicrobial Resistance in Specimens from a Tertiary Hospital's Surgical Ward.

Surgery has revolutionized the practice of medicine by allowing the treatment of conditions amenable to conservative medical management with some of them pathophysiologically involving the prevalence of pathogenic microorganisms. On the other hand, infections such as surgical site infections or urinary tract infections may complicate patients hospitalized in surgical wards leading to considerable morbidity, mortality, and increased healthcare-associated costs. The aim of this study was to present the microbiological characteristics and antimicrobial resistance of all isolates identified in microbiological specimens from a surgical ward of a tertiary hospital in Greece during a six-year period. Only specimens that yielded at least one microorganism were included in the analysis. In total, 1459 strains in 789 positive cultures were isolated. The most common sample sent to the microbiology department was pus from surgical wounds. The most common pathogens among all 1459 strains isolated were Enterobacterales at 33% (n = 482), however, the most common genus was Enterococcus at 22.3% (n = 326). Antimicrobial resistance against third-generation cephalosporins was 23% (n = 111/482) among Enterobacterales, while, the rate of vancomycin-resistant enterococci (VRE) was 18.5% (n = 60/324) among Enterococcus species and was increasing in the last years of the study. Antimicrobial resistance of Acinetobacter baumannii to carbapenems was 68.8% (n = 11/16), which was lower than the corresponding rate in other wards in Greece. The antimicrobial resistance rates noted herein raise questions regarding the appropriateness of currently suggested antimicrobials in guidelines and imply that a revision could be required. Practicing clinicians should always be aware of local microbiological data that allow the selection of appropriate antimicrobials for the management of infections. Finally, the increasing rates of VRE noted herein mandate further actions from the point of infection control and antimicrobial stewardship.
