ABSTRACT
BACKGROUND: Work is a daily activity with various conditions, exposures, and habits that may affect health either positively or negatively. Aim of this study was to investigate the relationship between occupational factors and conditions, and the occurrence of gastrointestinal disorders. METHODS: We enrolled in this study a sample of 891 consecutive individuals, who were examined by standard colonoscopy and gastroscopy and interviewed regarding their working conditions and exposures. Consecutively, data were statistically analyzed to explore possible associations. RESULTS: Peptic ulcer diagnosis was associated with reports of muscle pain/headache [odds ratio (OR): 3.656, 95 % confidence interval (95% CI): 1.898-7.043], with working in shifts (OR: 2.463, 95% CI: 1.058-5.731), and with the presence of occupational stress (OR: 2.283, 95% CI: 1.162-4.486). Gastritis was associated with muscle pain/headache (OR: 2.258, 95% CI: 1.096-4.652), shift work (OR: 3.535, 95% CI: 1.345-9.29), occupational stress (OR: 2.182, 95% CI: 1.072-4.444), and sedentary work (OR 0.275 lower risk 95% CI: 0.113-0.671). Ulcerative colitis was associated with muscle pain/headache (OR: 6.211, 95% CI: 2.162-17.840) and occupational stress (OR: 6.418, 95% CI: 2.243-18.361), while Crohn's disease diagnosis with muscle pain/headache (OR: 3.554, 95% CI: 1.628-7.759), frequent ordering food at work (OR: 4.928, 95% CI: 2.3-10.559), occupational stress (OR: 3.023, 95% CI: 1.413-6.469), work with intense physical activity (OR: 0.665 lower risk, 95% CI: 0.252-0.758). Colon cancer diagnosis was associated with frequent ordering food at work (OR: 2.739, 95% CI: 1.268-5.916) and occupational stress (OR: 3.175, 95% CI: 1.384-7.286), while stomach cancer diagnosis with ordering food at work (OR: 2.794, 95% CI: 1.154-6.763) and exposure to dust (OR: 5.650, 95% CI: 1.551-20.582). Finally, presence of polyps was associated with ordering food at work (OR: 2.154, 95% CI: 1.135-4.091), and constipation with ordering food at work (OR: 2.869, 95% CI: 1.451-5.672), occupational stress (OR: 2.112, 95% CI: 1.097-4.066), and occupational noise (OR: 0.248, 95% CI: 0.084-0.737). CONCLUSION: The incidence of the gastrointestinal diseases is affected by occupational exposures and related lifestyle habits. HIPPOKRATIA 2017, 21(2): 74-79.
ABSTRACT
AIM: Eosinophils are potent proinflammatory cells that are involved in the pathogenesis of ulcerative colitis (UC). We evaluated the infiltration of eosinophils into the lamina propria in patients with active and inactive ulcerative colitis (UC) and investigated its clinical significance, among other variables, in predicting the outcome of medical treatment in active disease. METHOD: We studied colorectal biopsy specimens from 18 UC patients with disease in long-standing remission, from 22 patients with active disease who responded to therapy (12 with complete response and 10 with partial response) and from 10 patients who were nonresponders. Demographic information was obtained at baseline, and clinical, endoscopic and laboratory data were obtained at baseline and 12 weeks post-treatment. We evaluated five histological features: mucosal ulceration; mucosal erosions; crypt abscesses; cryptitis; and eosinophilic infiltration of the lamina propria. The severity of these lesions was graded as: none or minimal; mild; moderate; or severe. Statistical analyses were performed between responders and nonresponders for differences in demographic, clinical, laboratory, endoscopic and histological parameters. RESULTS: Laboratory, endoscopic and histological parameters were significantly improved after treatment only in the complete responders group. Analyses of baseline data revealed no significant differences in parameters between complete or partial responders and nonresponders, except for a less severe eosinophilic infiltration of lamina propria in complete responders (P < 0.05). Multiple logistic regression analysis showed that severe eosinophilic infiltration in colonic biopsies was the most significant predictor of poor response to medical therapy. CONCLUSION: Assessing the severity of eosinophilic infiltration in the lamina propria of colonic biopsies in patients with ulcerative colitis could be a valuable predictive tool of response to medical therapy.

PURPOSE: Postoperative enteral paresis constitutes a common problem for surgeons around the world. Evidence by many authors suggests that colonic inertia constitutes a major component of postoperative enteral paresis. This study aims at comparing the effect of laparoscopic versus open cholecystectomy on colonic transit time in humans. MATERIALS AND METHODS: In this study, were included a total of 29 patients suffering from cholelithiasis, divided into two groups, a laparoscopic cholecystectomy and an open cholecystectomy group. All patients ingested one capsule containing 24 radiopaque markers on the day of the operation, and plain abdominal films were obtained on the 3rd postoperative day. The number of remaining markers was counted, and the percentage of rejected markers was calculated. For the statistical analysis, SPSS for windows version 12 was used. RESULTS AND DISCUSSION: The study's results show a significant difference in postoperative colonic motility, in favor of the laparoscopic cholecystectomy group (P = 0,001). Causative interpretation of these results is difficult, mainly due to the multifactorial nature of postoperative colonic hypomotility. CONCLUSION: The present study suggests an advantage of laparoscopic cholecystectomy, as far as the duration of postoperative colonic paresis is concerned.

Laparoscopic colorectal surgery (LCRS) is a safe, effective and cost-efficient option for the treatment of various benign and malignant conditions. However, its implementation to surgical practice is still limited. That is mainly due to its association with a steep learning curve. We performed a review of the literature to determine whether quality training in LCRS can reduce that learning curve and lead to better clinical outcomes. We concluded that a structured training program with pre-clinical phase focused on basic skill acquisition and a clinical phase focused on mentoring from experts can shorten the learning curve and improve clinical outcomes.

OBJECTIVE: The objective is the investigation of Joint Hypermobility (JH) and the Hypermobility Syndrome (HMS) in patients with inflammatory bowel disease (IBD). METHODS: We examined 83 patients with IBD and 67 healthy individuals for the presence of JH. Patients were excluded if they were under 18 or over 50 years of age and if they had other conditions which affect joint mobility. The x(2) and the Fisher exact test were used appropriately between study groups. Odds ratios (ORs) for the risk of JH and HMS in IBD groups were calculated. RESULTS: A total of 150 individuals (83 IBD patients and 67 healthy controls) participated in the study. 69 IBD patients, 41 with Crohn's Disease (CD) and 28 with ulcerative colitis (UC), were finally eligible. JH was detected in 29 CD patients (70.7%), in 10 UC patients (35.7%), and in 17 healthy control subjects (25.4%). Significant difference was detected on JH in CD patients as compared to UC patients (P = .0063) and controls (P < .0001). The estimated OR for JH was 7.108 (95% CI: 2.98-16.95) in CD and 1.634 (95% CI: 0.63-4.22) in UC patients. HMS was detected in 5 (12.2%) CD and in 1 (3.57%) UC patients. The OR for HMS in CD was 3.75 (95% CI: 0.41-34.007), while 7 (17.1%) CD patients had overlapping symptoms for both HMS and early spondylarthropathy. CONCLUSIONS: JH and the HMS are common in CD patients, thus articular manifestations should be carefully interpreted. This implies an involvement of collagen varieties in the pathogenesis of IBD.
ABSTRACT
There are several studies suggesting the paradoxical simultaneous presence of hypertensive lower oesophageal sphincter and gastroesophageal reflux disease. We present a case of a 22-year-old male patient who was examined in our outpatient clinic with oesophageal food bolus impaction during a meal, severe chest pain and drooling. Manometry revealed a hypertensive lower esophageal sphincter pressure (resting pressure 35 mmHg) and pHmetry revealed a DeMeester score > 14.72 (43.27). Six months after therapy with lansoprazole, manometry revealed a normal lower oesophageal sphincter (resting pressure 14 mmHg) and the DeMeester score was < 14.72 (5.89). The patient is now asymptomatic. This report is the only published case which exhibits the normalization of lower oesophageal pressure 6 months after gastroesophageal reflux disease management with lansoprazole, thus proving and establishing the above ''paradox''.

BACKGROUND: Several studies have shown a migration in the occurrence of colorectal cancer (CRC) toward a proximal colonic location. The aim of this study was to examine the interrelationship between the anatomical distribution of CRC and gender, age at presentation, and incidence rates for the disease in the inhabitants of Thrace, Northern Greece. METHODS: A retrospective study was conducted on CRC cases diagnosed in a northern part of Greece (Evros region, 150.000 inhabitants), in the First Department of Surgery of the University General Hospital of Thrace, between 1982 and 1997. Two time periods were compared (1982-1989 and 1990-1997), at which age at diagnosis (28-88 years), gender, the incidence and subsite location of CRC were identified in the patients. Tumors were classified into right-sided cancers (from the cecum to and including the splenic flexure), left-sided cancers (located in the descending and the sigmoid colon), and rectal cancers (rectal lesions). The chi-square test and Fischer's exact test were used to compare the data. RESULTS: During the entire study period (1982-1997), 143 cases of CRC were identified in our department. This cohort comprised 71 males and 72 females, with mean ages of 66 years and 64.7 years, respectively. The population remained almost stable during this time period. The incidence of CRC was significantly higher in the latter part of the study (1990-1997 compared to 1982-1989) for both genders (p < 0.001), with this increase being higher among the female patients with CRC (by 17.32%, p = 0.474). The analysis also revealed that the disease occurred at a significantly higher frequency at a later age (p = 0.002), especially in patients with RC (p = 0.001). A proximal migration of CRC was observed in the latter part of the study (p = 0.495), with the frequency of right-sided cancers increasing significantly among the females (by 119%, p = 0.025). CONCLUSIONS: The incidence of CRC has increased in our region. In addition, a proximal migration of tumors over time was identified, especially in older and female individuals, which was linked to a decrease in the incidence of left colon cancer. These findings have important implications for the choice of CRC screening strategies.

We report a case of a 65-year-old woman who presented with recurrent episodes of severe, postprandial abdominal pain followed by projectile vomiting. Gastroscopy revealed a large polyp in the prepyloric region. During peristalsis, the polyp was repeatedly 'passing' through the pylorus into the duodenal bulb, hence obstructing the lumen. The polyp was eventually removed in a piecemeal fashion. Histopathologic examination revealed an inflammatory fibroid polyp (known also as Vanek's tumour). A brief review on inflammatory fibroid polyps follows.

Trimethoprim-Sulfomethoxazole (TMP-SMX) related hepatotoxicity and associated severe systemic reaction are not frequent and documented only in case reports. We report a case of a 30-year-old man, who underwent a 15-day therapy with TMP-SMX for urinary tract infection and two weeks later developed acute cholestatic hepatitis, fever and a skin rash followed by severe systemic reaction. He was admitted in Intensive Care unit and with supportive therapy and prednisolone administration, he showed subsequent improvement over a period of few days. He had fully recovered months later. All tests for other causes of liver disease were negative and his liver biopsy showed evidence of drug-induced hepatic injury.

BACKGROUND AND STUDY AIMS: Specialized columnar epithelium of Barrett's esophagus is a precursor of dysplasia and adenocarcinoma, and methylene blue selectively stains this type of epithelium. The present prospective study examined the detection of short-segment and long-segment Barrett's esophagus using methylene blue chromoendoscopy-directed biopsies, in comparison with biopsies directed using conventional endoscopic criteria. PATIENTS AND METHODS: Biopsies were obtained from macroscopically conspicous areas in the distal esophagus observed during conventional endoscopy in a total of 975 patients. Immediately after conventional biopsies, the distal esophagus was sprayed with methylene blue and directed biopsies were then obtained from the stained regions. All patients with a histologically established Barrett's esophagus underwent a second upper gastrointestinal endoscopy within 1 year in order to assess the reproducibility of the method. RESULTS: In a total of 3,900 conventional biopsy specimens (without staining), 54 specimens (1.4%) were found to show Barrett's esophagus and were confined to 16 of the 975 patients (1.6%). Of the total 130 directed biopsy specimens obtained during chromoendoscopy, 114 (87.7%) revealed Barrett's esophagus (P<0.00001) and were confined to 35 of the 975 patients (3.5%; P < or = 0.001). The findings were confirmed within 1 year in all dye-positive patients. CONCLUSIONS: Chromoendoscopy with methylene blue appears to be an accurate, simple, safe, inexpensive, and reproducible method of detecting specialized columnar epithelium in Barrett's esophagus.

Hepatocellular carcinoma remains a disease with a poor and dismal prognosis, and all forms of currently available conventional therapies are rarely beneficial. However, in recent years, combined targeting locoregional immunochemotherapy has been reported with very promising results. Adoptive immunotherapy with LAK cells (lymphokine-activated killer cells) and recombinant interleukin-2 is becoming one of the new modalities to reconstitute the depressed immune status of the tumor-bearing host. Interleukin-2, gamma-interferon, and interleukin-12 induce cytolytic activity of LAK and natural killer cells and are considered for cellular activation to locoregional immunotherapy before, after resection or even in unresectable hepatocellular carcinomas. Spleen is a suitable organ for LAK cell induction because it has densely packed lymphocytes. The strategy of administration of both interleukin-2 and gamma-interferon into the spleen for in vivo immunostimulation is based on the well-known synergism of the above cytokines. LAK cells have cytotoxic activity against a variety of tumor cells. In particular, LAK cells exhibit efficacy against lung and liver malignant lesions, as suggested by their trafficking pattern; activated killer cells injected i.v. into humans appeared in the lung early and were subsequently rapidly redistributed to the liver and spleen. Lipiodol-Urografin emulsion is probably an ideal cytokine/anti-cancer drug carrier suitable for the combined locoregional immunochemotherapy because during its preferential retention in the vascular network of the spleen and tumor, a gradual release of both immuno- and chemotherapeutical drugs bound to emulsion droplets is achieved ensuring a prolong half life for these drugs. Recent data point to the potential of considering intratumoral or intravascular use of adenovirus carrying interleukin-12 gene, and/or p53-based gene therapy as possible therapeutic strategies in patients with hepatocellular carcinoma.
