Urinary bladder-containing incarcerated inguinoscrotal hernia: a case report.

Inguinoscrotal hernia containing the urinary bladder is a rare entity found in 1-4% of inguinal hernias, while patients rarely present symptoms of urinary dysfunction. We present the case of a 79-year-old Caucasian male with acute renal dysfunction and incarcerated inguinoscrotal hernia containing the entire urinary bladder. The patient presented in the surgical emergency department due to an incarcerated right inguinoscrotal hernia and deteriorated renal function. Preoperatively, ultrasound imaging was performed, which showed the presence of the whole bladder in the hernia sac. The bladder was repositioned to its anatomic position and hernia was repaired through a modified Lichtenstein technique. In patients with inguinoscrotal hernia and acute urinary tract symptoms, surgeons should be aware of the possibility of inguinal bladder hernia. Preoperative imaging can help in preventing intraoperative bladder damage.

Spontaneous massive duodenal perforation after ovarian cancer treatment with bevacizumab.

Bevacizumab has been used as an effective drug for ovarian cancer. However, serious adverse effects, such as gastrointestinal perforation, can occur. Spontaneous gastrointestinal perforation is an uncommon, yet life-threatening complication related to bevacizumab administration. We present the case of a 65-year-old Caucasian female who presented with acute abdomen 10 days after the first administration of bevacizumab for ovarian cancer treatment, and she was diagnosed intraoperatively with a massive duodenal perforation. Bowel perforation after bevacizumab administration is a serious and potentially lethal complication. Careful follow-up of the patients is necessary in order to detect any signs of this condition in time.

Spontaneous rupture of a splenic artery aneurysm treated with a spleen-preserving procedure: a case report.

Splenic artery aneurysm is a rare and life-threatening condition, in case of spontaneous rupture. A rare case of such a rupture, treated successfully with an endovascular procedure, is presented. A 21-year-old man presented to the emergency department after an episode of loss of consciousness. After initial conservative treatment, he developed hemodynamic instability 12 hours later, with concurrent diffuse abdominal pain. Abdominal CT revealed a ruptured splenic artery aneurysm, which was immediately treated with coil embolization. The patient had an uneventful recovery and was discharged on the 12th day after the procedure. Although open surgery is the choice of treatment in cases of ruptured splenic artery aneurysms, endovascular embolization can also be considered a safe procedure with low complication and mortality rates.

Rheumatoid nodules in thyroid gland parenchyma as an expression of rheumatoid arthritis: a case report.

BACKGROUND: The rheumatoid nodule is the most common extra-articular manifestation of rheumatoid arthritis. When present, it is readily identified in conventional hematoxylin and eosin sections. CASE PRESENTATION: We report a case with several rheumatoid nodules in a thyroid gland of a 33-year-old Greek woman with a 3-year history of rheumatoid arthritis treated with methotrexate, after having total thyroidectomy for hypothyroidism. CONCLUSION: To the best of our knowledge, this is the first time that rheumatoid nodules have been encountered in the thyroid gland.

Primary greater omental torsion as a cause of acute abdomen-a rare case report.

Greater omental torsion is a rare entity that can cause acute abdominal pain, may mimick other abdominal pathologies, and is difficult to be diagnosed preoperatively. We present a case of a male patient with greater omental torsion mimicking the symptoms of acute appendicitis. A 31-year-old male patient presented with right scrotal pain, initially treated by the urologists, however, 24 h later, he presented right lower quadrant pain, with characteristics of acute appendicitis. After finding in ischemic inflammatory mass on McBurney incision, an exploratory laparotomy was performed, revealing torsion of the greater omentum. Torsion of the greater omentum can be a cause of acute abdomen and could be misdiagnosed with acute appendicitis. Preoperative diagnosis is not easy and resection of the affected tissue is the preferred treatment of choice.

Acute appendicitis as the first presentation of appendiceal metastasis of gastric cancer-report of a rare case.

Metastatic tumors of the appendix is a rare entity, whereas only limited data involving metastasis arising from gastric cancer has been reported. Herein, the case of gastric adenocarcinoma metastasis presenting as acute appendicitis is reported. A 53-year-old male, with a history of subtotal gastrectomy due to gastric adenocarcinoma 3 years before, was referred to the Emergency Department with symptoms of acute appendicitis. While this condition was confirmed intraoperatively, histology examination and comparison with the previously excised gastric specimen indicated that metastasis of gastric adenocarcinoma to the appendix was present. Metastatic appendiceal carcinoma arising from the stomach is an extremely rare condition, associated with poor prognosis. Aggressive treatment of the solitary lesion may present favorable results.

Prediction of Lumbar Disc Herniation Patients' Satisfaction with the Aid of an Artificial Neural Network.

AIM: To identify key determinants of lumbar disc herniation (LDH) patients' satisfaction and to evaluate the efficiency of an artificial neural network (ANN) model to prognosticate satisfaction derived from the hospital stay in this specific patient group. MATERIAL AND METHODS: A single item question was used to assess patient satisfaction. Principal component analysis evaluated several aspects of care (15 items). An ANN encompassed all variables and its prediction ability was tested. The ANN performance was correlated to a binary logistic regression (BLR) model. RESULTS: Higher levels of satisfaction were reported by females, older patients, Greeks, and patients with elementary education staying in not rural areas. A history of a single previous hospitalisation was correlated with more satisfaction. The accuracy of ANN was 96% for satisfaction prediction outperforming the BLR model. CONCLUSION: Satisfactory health services are influenced by sex, age, nationality, and number of prior admissions. The self-perceived health state plays also a crucial role. The current study is the first one reporting on the capability of an ANN to accurately predict the satisfaction levels of LDH patients.

Patient-related delay in presentation for cutaneous squamous cell carcinoma. A cross-sectional clinical study.

BACKGROUND: Delayed diagnosis of squamous cell carcinoma (SCC) increases recurrence, metastatic potential, and management costs. This study aims to identify risk factors of patient-related delayed presentation in cutaneous SCC. PATIENTS AND METHODS: A total of 513 patients, who first sought care for cutaneous lesions that were subsequently removed and histologically confirmed as SCCs, were included. Attitude to symptoms, psychosocial profile, and reasons for delayed presentation were obtained via a structured questionnaire-based interview. First presentation > 3 months from the onset of symptoms was considered as delayed. RESULTS: Mean presentation time was 3.90 ± 2.05 months, while 186 patients delayed presentation. Multivariate logistic regression analysis revealed that serious co-morbidity (p = 0.003), low education level (p < 0.001), non-recognition of the seriousness of symptoms (p < 0.001), a 'wait and see' attitude (p < 0.001), and fatalism (p = 0.005) were independent determinants of significantly higher risk for delayed presentation. In contrast, female sex (p = 0.006), new lesion (p = 0.012), accessible topography (p = 0.019), size increase (p = 0.002), color change (p = 0.017), non-healing wound (p = 0.048), and presence of social support/advice (p < 0.001) were independent determinants significantly associated with early presentation. CONCLUSION: Recognition of symptom seriousness and elimination of factors hindering self-referral may increase awareness and promote early patient presentation and diagnosis of cutaneous SCC.

Interleukin-1 associations in inflammatory bowel disease and the enteropathic seronegative spondylarthritis.

PURPOSE: This study aims to investigate any associations of the proinflammatory cytokine IL-1 in treated patients with inflammatory bowel disease (IBD) and the enteropathic seronegative spondylarthritis (eSpA). METHODS: Thirty-four patients with Crohn's disease (CD), 26 with ulcerative colitis (UC) and 14 patients with SpA participated in the study. Valid clinical indexes, CRP values and the endoscopic and histologic examination were used for the determination of disease activity. IL-1α, IL-1ß, IL-1 receptor antagonist (IL-1Ra) were measured by ELISA. Nonparametric tests were used for continuous and categorical data. RESULTS: Enteropathic SpA diagnosed in 29.4 % CD and 30.8 % UC patients. Active disease had 58.8 % CD (aCD), 76.9 % UC and 50 % SpA patients. Active and inactive CD (iCD) significantly differ on IL-1α levels (11.2 vs. 3.9 pg/ml; p = 0.034). Active and inactive UC significantly differ on IL-1ß (3.7 vs. 2.3 pg/ml; p = 0.054) and IL-1Ra levels (15.9 vs. 12.7 pg/ml; p = 0.023). Active and inactive SpA (iSpA) significantly differ on IL-1Ra (16.9 vs. 14.8 pg/ml; p = 0.033) and marginally on IL-1α levels (20 vs. 3.9 pg/ml; p = 0.06). Patients with aCD/ieSpA exhibited significant differences on IL-1α (p = 0.022) compared to those with iCD/ieSpA. CONCLUSIONS: IL-1α is associated with CD activity, while IL-1ß and IL-1Ra are associated with UC activity in treated patients with IBD. Prominent cytokine in SpAs seems to be IL-1α.

Non-Hodgkin lymphoma and GIST: molecular pathways and clinical expressions.

We report the case of a 64-year-old woman with a gastrointestinal stromal tumor and a diffuse large cell lymphoma. For this case, we conducted a literature review in an attempt to correlate these two neoplasms on a molecular basis. Diffuse large cell lymphoma is a subtype of non-Hodgkin lymphomas. The etiologic factor of these lymphomas is considered to be the mutations or allelic losses of the TP53 tumor suppressor gene and the overexpression of the bcl-2 oncogene. Gastrointestinal stromal tumors are mesenchymal tumors, which are typically defined by the expression of c-KIT (CD117) and CD34 genes in the tumor cells. Although there are references to dispersants in the literature about patients with both non-Hodgkin lymphoma and gastrointestinal stromal tumors, there is no common molecular pathway between these two diseases. In conclusion, there is no indication that these two neoplasms are relevant on a molecular basis.

Tuberculosis in the peritoneum: not too rare after all.

Peritoneal tuberculosis is rare with increased incidence rates in recent years. The absence of characteristic clinical features of the disease often makes its diagnosis difficult and elusive. We present the case of 61-year-old female with peritoneal tuberculosis. The patient suffered from abdominal pain for a period of 5 months prior to admission. The diagnosis was established on the basis of findings from an abdominal computed tomography scan, a chest radiograph and histopathological analysis of the laparoscopic resection of the two masses. The patient was discharged from hospital receiving a fourfold antituberculous treatment with isoniazid, rifampicin, pyrazinamide and ethambutol. A high index of suspicion and a combination of radiologic, endoscopic, microbiologic and histopathological examination achieves diagnostic accuracy and prevents clinical mismanagement.

Is Post-ERCP Pancreatitis a Genetically Predisposed Complication?

Background/Objectives. Pancreatitis remains the most common complication of ERCP. History of post-ERCP pancreatitis is an independent risk factor for a new episode, suggesting a genetic background. The N34S mutation in serine protease inhibitor Kazal type 1 (SPINK 1) gene may downregulate the threshold for the development of pancreatitis. The aim of the present study is to evaluate the presence of this mutation among patients with post-ERCP pancreatitis. Methods. During a period of four years, thirty patients with post-ERCP pancreatitis entered the study. Patients and procedural data were collected, focusing on risk factors for pancreatitis. Blood samples were taken for genetic testing for the presence of N34S mutation in SPINK 1 gene. After DNA extraction, we used an allele-specific polymerase chain reaction as an initial screening method for the N34S mutation, and in order to confirm the results and to determine the hetero- and homozygosity genotype status, we used a restriction fragment length polymorphism (RFLP) method. Results. None of the thirty patients was found to carry the N34S mutation, with both of the applied methods. Patients had an average of two of the known risk factors. Conclusion. SPINK1 N34S mutation does not seem to play a role in post-ERCP pancreatitis, but larger studies needed to confirm our results.

Bevacizumab, capecitabine, amifostine, and preoperative hypofractionated accelerated radiotherapy (HypoArc) for rectal cancer: a Phase II study.

PURPOSE: Bevacizumab has established therapeutic activity in patients with metastatic colorectal cancer, and anti-vascular endothelial growth factor therapy enhances the activity of radiotherapy in experimental models. We assessed the feasibility and efficacy of preoperative radiochemotherapy combined with bevacizumab in patients with rectal cancer. METHODS AND MATERIALS: Nineteen patients with radiologic T3 and/or N+ rectal carcinoma were treated with preoperative conformal hypofractionated accelerated radiotherapy (3.4 Gy in 10 consecutive fractions) supported with amifostine (500-1,000 mg daily), capecitabine (600 mg/m(2) twice daily, 5 days per week), and bevacizumab (5 mg/kg every 2 weeks for 2 cycles). Surgery followed 6 weeks after the end of radiotherapy. A cohort of 14 sequential patients treated with the same regimen without bevacizumab was available for comparison. RESULTS: Grade 2 or 3 diarrhea was noted in 7 of 19 patients (36.8%), which was statistically worse than patients receiving the same regimen without bevacizumab (p = 0.01). A higher incidence of Grade 2 or 3 proctalgia was also noted (21.1%) (p = 0.03). Bladder and skin toxicity was negligible. All toxicities regressed completely within 2 weeks after the end of therapy. Pathologic complete and partial response was noted in 7 of 19 cases (36.8%) and 8 of 19 cases (42.1%). Within a median follow-up of 21 months, none of the patients has had late complications develop and only 1 of 18 evaluable cases (5.5%) has had locoregional relapse. CONCLUSIONS: Bevacizumab can be safely combined with hypofractionated radiotherapy and capecitabine as a preoperative radiochemotherapy regimen for patients with rectal cancer. The high pathologic complete response rates urges the testing of bevacizumab in randomized studies.

Hypofractionated accelerated radiotherapy, cytoprotection and capecitabine in the treatment of rectal cancer: a feasibility study.

BACKGROUND: This is a report on the feasibility and efficacy of hypofractionated accelerated radiotherapy combined with amifostine cytoprotection (hypoARC) and capecitabine in the treatment of rectal adenocarcinoma. PATIENTS AND METHODS: Twenty-seven patients (pts) received pre- (14 pts) or postoperative (13 pts) conformal radiotherapy with 10 consecutive fractions of 3.4 Gy in 12 days, supported with subcutaneously administered high-dose amifostine (up to 1000 mg) and capecitabine (daily dose of 600 mg/m2 twice a day, 5 days per week for 4 weeks). Ten additional patients with inoperable tumors received a higher dose (15 fractions of 3.4 Gy) as a radical intervention and 5 received a lower dose for palliation. RESULTS: Chemotherapy-related toxicity was minimal and radiation grade 2 diarrhoea and proctitis was noted in 3/42 and 4/42 cases, respectively. No peri- or postoperative complications were noted in patients receiving pre-operative radiochemotherapy. Significant tumor regression was confirmed in post- RT CT-imaging and major histological responses were noted in 85% of cases treated before surgery. Late toxicity (median follow-up 26 months) was negligible. The 2-year local relapse-free survival was 85-90% in patients treated with pre- or postoperative radiotherapy and 35% in patients with inoperable tumors. CONCLUSION: Capecitabine-based hypoARC is feasible with only minimal early and late toxicity and encouraging efficacy.

Impact of hiatal hernia on histological pattern of non-erosive reflux disease.

BACKGROUND: Hiatus hernia (HH) has major pathophysiological effects favoring gastroesophageal reflux and hence contributing to esophageal mucosa injury, especially in patients with severe gastroesophageal disease. However, prospective studies investigating the impact of HH on the esophageal mucosa in non-erosive reflux disease (NERD) are lacking. This study evaluated the association between the presence of (HH) and the histological findings in symptomatic patients with NERD. METHODS: Fifty consecutive patients with gastroesophageal reflux disease (GERD) were enrolled. After conventional endoscopy, Lugol solution was applied and biopsy specimens were obtained. Histological parameters including basal zone hyperplasia, papillary length and cellular infiltration were evaluated. The chi-square test with Yates' correlation was used for comparing discrete parameters between groups. However, Fisher's exact probability test was used where the expected frequencies were lower than 5. Wilcoxon's test for unpaired samples was preferred in cases of semi-quantitative parameters. RESULTS: The presence of HH along with more severe findings (0.01

Gastroesophageal reflux disease and Helicobacter pylori: lack of influence of infection on oesophageal manometric, 3-hour postprandial pHmetric and endoscopic findings.

AIM: To investigate the relationship between Helicobacter pylori and gastro-oesophageal reflux disease according to manometric and pHmetric findings. METHOD: Fifty-nine consecutive patients with reflux symptoms and endoscopic evidence of mild oesophagitis, were recruited. Manometry and ambulatory pHmetry were performed in all patients, as well as the 3-hour postprandial pHmetry, as a more flexible and well tolerable test. RESULTS: There were no significant differences between Helicobacter pylori positive and negative patients regarding age, sex ratio and endoscopic severity of oesophagitis. There was no difference in prevalence of abnormal oesophageal peristalsis between the two groups (Fisher's exact test, p=NS). Differences were also not found regarding lower oesophageal sphincter pressure between the two groups (mean PLOS 12.86+/-4.39 mmHg and 13.1+/-4.61 mmHg respectively; p=0.840). Finally, the mean values of DeMeester score were 60.38+/-48.04 and 67.64+/-51.04 respectively (p=0.576). CONCLUSION: Helicobacter pylori infection does not influence oesophageal peristalsis, the lower oesophageal sphincter pressure and the acidity of refluxates into the oesophageal lumen, in patients with established gastro-oesophageal reflux disease (esophagitis grade A and B).
