RESUMEN

BACKGROUND: Acute abdominal pain is one of the most common symptoms that emergency department physicians encounter during their practice. The difficult task of early diagnosis and management of abdominal pain becomes more complicated when it involves elderly patients. The aim of this study was to evaluate the presence of age based differences regarding the management of acute non-traumatic abdominal pain in the Emergency Department. METHODS: We retrospectively analyzed the medical records of 933 patients with acute non-traumatic abdominal pain in the emergency department of a regional hospital during one year period. RESULTS: There were no differences between native and foreign elder patients regarding the use of imaging studies and discharge status. Although no differences were detected regarding the clinical presentation and management within the Emergency Department, elder patients with abdominal pain had a higher likelihood of being admitted for further hospitalization and were more often submitted to diagnostic examinations. The elder group had a trend towards lower number of cases of non-specific abdominal pain in comparison with the non-elders. Between male and female elders no statistically significant differences were detected. CONCLUSIONS: A thorough work-up is essential for all patients. The clinician should always be alerted, since elderly patients may require more tests and they should have a low threshold for hospital admission.

RESUMEN

BACKGROUND: Gastrin has been shown to exert carcinogenic effect to the epithelium of the colon. This study examines whether hypergastrinemia and H. pylori infection -especially infection by the CagA+ strain- are statistically associated with colorectal cancer and examine possible correlations with the colorectal cancer stage and lymph node metastasis. METHODS: In this prospective case-control study, fasting serum samples from 93 consecutive patients with colorectal cancer treated in a university surgical clinic were preoperatively collected and serum levels of gastrin were measured. A group of 20 age matched hernia patients were used as controls. The pathology report of the specimens was documented and statistical analysis of the data where performed with the spss 17 statistical suite. RESULTS: H. pylori IgG antibodies was reported in 66/93 (71%) in the colorectal cancer group and 13/20 patients in the control group (65%), the difference having non-statistical significance (P = n.s). The prevalence of cagA protein expression in the anti- H. pylori IgG+ patients were higher in the colorectal cancer group (56% positivity), when compared to the control group (38,4% positivity) but the difference was not of statistical significance (P = n.s). The mean levels of serum gastrin levels in the two groups did not significantly differ (Ca group 51.1 ± 36.6 pg/mL vs Control 49.8 ± 17.6 P = n.s.). Patients with lymph node metastasis had higher serum gastrin levels than patients without metastasis and this difference was statistically significant. (53.6 vs 41.06 pg/mL P = 0.025). CONCLUSIONS: Although the serum gastrin levels were not statistically different between the TNM stages of our patient cohort, our data found that serum gastrin levels were significantly higher in patients with lymph node metastasis. Whether gastrin is implicated in the ability of cancer cells to metastasize to the lymph nodes merits further research.

RESUMEN

The increasing use of laparoscopic cholecystectomy has led to an increased frequency of gallbladder perforation and subsequent gallstone spillage in the abdominal cavity. Occasionally unretrieved gallstones can cause infection, adhesions, and obstruction. Furthermore, spilt stones can cause erosion into adjacent organs and can migrate to distant sites, causing a variety of complications. We report the unusual case of a patient who presented with spontaneous erosion of gallstones through Grynfeltt's triangle, 1 year after laparoscopic cholecystectomy and review the current literature.

RESUMEN

Desmoid tumors are rare, benign fibroblastic tumors that are locally infiltrative and can cause extensive morbidity by destruction of adjacent vital structures. Due to the rarity of these tumors, evidence regarding optimal treatment protocols is drawn from case reports and single-arm series with small patient numbers. We report a case of a patient with a desmoid tumor of the left supraclavicular region that was diagnosed and treated in our department and a review of the current literature.

RESUMEN

The incidence of cutaneous adverse reactions to quinolones is low; moreover their development in patients with concomitant alcohol consumption is a phenomenon that has been scarcely reported. We present a case of 46-year-old male who developed erythema multiforme after ingestion of alcohol, while being treated with ciprofloxacin. The lesion was self-limiting and abstinence from alcohol permitted the completion of the course of therapy without any other adverse reaction.

RESUMEN

BACKGROUND: Several authors advocate spleen preserving distal pancreatectomy, because of the increased complication rate after splenectomy. METHODS: Postoperative complications and survival after distal and total pancreatectomy, were recorded and retrospectively analyzed according to spleen preservation. Patients, who underwent distal and total pancreatectomy without histologically proven adenocarcinoma, or extrapancreatic disease, were included in the cohort which was divided into splenectomy and no splenectomy groups. Statistical analysis was performed using Fisher's test. RESULTS: The study group consisted of 62 patients who underwent distal and total pancreatectomy between 26/11/1987 to 6/1/2006. Splenectomy was performed in 35 out of 62 patients (56.5%), distal pancreatectomy was performed in 49 out of 62 patients (79%). Morbidity rate was 28.6% in splenectomy group and 14.8% in the no splenectomy group (p = 0.235), while 30 days mortality rate was 2.9%; one patient died in the splenectomy group (p = 1). CONCLUSION: Spleen-preservation did not influence the outcomes after distal and total pancreatectomy in our series.

RESUMEN

To analyze the outcomes between identical and compatible liver transplantation (OLT) for fulminant hepatic failure (FHF) from September 1984 to November 2005. The patients were divided in three groups; group 1 (identical), group 2 (compatible) and group 3 (incompatible), according to the donor-recipient blood type matching. We analyzed several outcomes regarding mortality, patient and graft survival, incidence of acute graft rejection during the first postoperative month (30 days), incidence of biliary complications and indications of re-transplantation. We also analyzed the relationship of Coomb's positive test with postoperative hemolysis to all the above mentioned factors. During the study period, 168 males and 112 females underwent their first OLT for FHF, with 37.1% overall mortality and 42.1% overall graft failure rate. The results between group 1 (203 patients) and group 2 (73 patients) were comparable. A statistically significant difference was recorded in 1 year and overall graft survival between group 1 and group 2 (P = 0.049 and log-rank = 0.035 respectively). Coomb's positive test did not influence the outcomes. OLT in FHF can be safely carried out whether the donor organs are identical or compatible. Hemolysis (Coomb's positive test) after identical or compatible OLT does not influence the outcomes.
