Splenosis is a common benign condition that occurs after splenic rupture via trauma or surgery. The mechanism behind splenic cell autotransplantation begins with the splenic rupture, either from trauma or surgical removal. Splenosis is usually found incidentally and, unless symptomatic, surgical therapy is not indicated. Subcutaneous splenosis is an extremely rare form of splenosis, mostly observed in abdominal surgical scars. We report a case of subcutaneous splenosis, as well as a comprehensive review of the literature. In our case, a 43-year-old woman who had splenectomy after traumatic splenic rupture at the age of 7 years old presented for plastic reconstruction of her postoperative scar. Upon surgery, two asymptomatic subcutaneous nodules were incidentally discovered. The presence of splenic tissue was confirmed by the histological study. The nodules were not excised, as the patient was not symptomatic.

PURPOSE: Acute appendicitis within a femoral hernia is a rare condition that was first described by Rene Jacques de Garengeot. In the present study, we summarize the existing evidence on de Garengeot's hernia, with special emphasis on its clinical presentation and diagnostic approach. METHODS: A thorough search of the English-language literature published between 1980 and 2011 was performed. Studies reporting cases of de Garengeot's hernia were selected using specific inclusion criteria (description of femoral hernia appendicitis, statement of patient demographics and symptoms, and statement of diagnostic tests performed). RESULTS: Thirty-one studies that encompassed 36 patients (28 women, mean age 71.5 years) with de Garengeot's hernia were included in our analysis. Patients presented with a right groin mass in 35 (97 %) cases. The mass was almost always painful (n = 35, 97 %), while 14 (39 %) of the patients were febrile. Mean duration of symptoms was 5.17 days. Fifty-six percent of the groin masses were erythematous. Leukocytosis was present in 67 % of the patients, and 25 patients underwent imaging investigation with X-ray (n = 11), Ultrasound (n = 5) or Computed Tomography (CT, n = 9). Twenty percent of the Ultrasound and 44 % of the CT studies were diagnostic, leading to an overall rate of 14 % of femoral hernia appendicitis preoperative diagnosis. Eighty-one percent of the patients underwent herniorrhaphy with sutures while a mesh was used in 19 %. Mean hospital stay was 6.23 days. CONCLUSION: Preoperative diagnosis of de Garengeot's hernia is difficult due to its atypical clinical presentation. Further surgical treatment depends on the surgeon's sound clinical judgment.

Implications of the Incidental Finding of a MYCN Amplified Adrenal Tumor: A Case Report and Update of a Pediatric Disease Diagnosed in Adults. Case Rep Oncol Med. 2013;2013:393128.Abstract
MYCN is a well-known oncogene overexpressed in different human malignancies including neuroblastoma, rhabdomyosarcoma, medulloblastoma, astrocytoma, Wilms' tumor, and small cell lung cancer. While neuroblastoma is one of the most common childhood malignancies, in adults it is extremely rare and its treatment is based on pediatric protocols that take into consideration stage and genotypic features, such as MYCN amplification. Although neuroblastoma therapy has evolved, identification of early stage patients who need chemotherapy continues to pose a therapeutic challenge. The emerging prognostic role of MYCN phenotype of this disease is currently under investigation as it may redefine MYCN amplified subgroups. We describe an unusual case of adult neuroblastoma with MYCN amplification diagnosed incidentally and discuss possible therapeutic dilemmas.

Liver function tests in viremic and nonviremic chronic hepatitis B virus-infected pregnant women: importance of alanine aminotransferase/sodium ratio. Gastroenterol Nurs. 2013;36(6):422-8.Abstract
The major risk factor of perinatal transmission of Hepatitis B virus (HBV) infection is the level of maternal HBV-deoxyribonucleic acid (DNA) during the third trimester of pregnancy. The primary aim of this study was to evaluate the hematological and biochemical status in Hepatitis B e-antigen (HBeAg)-negative chronic HBV-infected pregnant women and to correlate the findings with the presence or absence of viremia. Ninety-five consecutive chronic HBV-infected pregnant women were evaluated between the 28th and 32nd week of gestation. Viral load was determined by using the COBAS TaqMan HBV test. Sixty-nine women were evaluated and 14 of them exhibited HBV-DNA levels higher than 2000 IU·ml. In this study, viremic women exhibited significantly higher alanine aminotransferase (ALT), creatinine, and uric acid values as well as significantly lower white blood cell count compared with nonviremic women. There was also a significant statistical difference concerning ALT/sodium ratio between viremic and nonviremic women (0.20 ± 0.22 vs. 0.10 ± 0.09, respectively, p= .024). The optimal cutoff points discriminating those women with a high probability to have detectable serum HBV-DNA were 0.092 for ALT/sodium ratio (sensitivity = 73.0%, specificity = 61.5%, area under the receiver operating characteristic curve [AUC] = 71.05%) and 12.8 IU/L for ALT (sensitivity = 73.0%, specificity = 63.0%, AUC = 72.2%). Chronic HBV-infected pregnant women with ALT/sodium ratio ≥ 0.11 had the higher probability of having serum HBV-DNA levels higher than 2000 IU/ml (sensitivity = 76.92%, specificity = 58%, AUC = 62.38%). Presence of HBV-DNA in maternal blood during the third trimester of pregnancy is significantly associated with maternal serum ALT levels in HBeAg-negative chronic HBV-infected pregnant women. Women with an ALT/sodium ratio greater than 0.092 have the higher probability of HBV-DNA presence in maternal blood whereas an ALT/sodium ratio greater than 0.11 could discriminate those women with HBV-DNA levels higher than 2000 IU/ml.

We report our two-year experience in the endovascular treatment of brain aneurysms in relation to their parent artery wall. We prospectively recorded patients with intracranial aneurysms (107 ruptured - 38 unruptured) treated with coiling during a two-year period: 145 patients, 94 females and 51 males - mean age 56 years. The aneurysms were divided into side-wall (A) and bifurcation (B) groups. A total occlusion rate was noted in post-embolization angiograms in 101 aneurysms (70%) with a morbidity of 4%. No angiographic recurrence arose in the six-month follow-up. The two groups had a similar total occlusion rate (68.31% and 71.8% respectively), while the complication rate was 3% in group A and 4.7% in group B. Significant differences between the two groups were noted in the number of assisted coiling cases: 28 out of 60 cases (46.7%) in group A - 14 out of 85 cases (16.5%) in group B. Further statistical analysis showed strong dependencies for the type of endovascular procedure between the ruptured and unruptured aneurysms in both groups (p 0.000<0.05), but no dependencies between the aneurysm occlusion rate and the ruptured or non-ruptured aneurysms, or between the occlusion rate and the type of endovascular procedure (p 0.552>0.05 and 0.071>0.05 respectively). In conclusion, the anatomic relation of the aneurysm sac with the wall of the parent artery is important, as significant differences in endovascular practice, devices and techniques were noted between side-wall and bifurcation aneurysms.

Central vascular catheters versus peripherally inserted central catheters in nurse anesthesia. A perspective within the Greek health system. J Vasc Access. 2013;14(4):373-8.Abstract
PURPOSE: We present a study comparing the insertion of central vascular catheter (CVC) and peripherally inserted central catheter (PICC) by an anesthesia nurse at 2 Greek University Hospitals. METHODS: Eighty patients, aged 20-80 years, were enrolled in the study. Patients were divided into 2 groups. In group A (41 patients), a CVC was inserted in the internal jugular vein. In group B (39 patients), a pressure-injectable PICC was inserted in the basilica vein. RESULTS: Correlations between the methods applied, the patients' characteristics, the procedures' characteristics and the overall satisfaction scores for each procedure were examined. The final results show that the patients of group B (PICC method) were more satisfied with the procedure than the patients of group A (CVC method), at the statistical significance level of a=0.01. Also, according to the results of the analysis, the PICC method offers significantly more comfort and relative satisfaction than the CVC method, at the statistical significance level of a=0.01. The satisfaction scores of "physicians" were statistically more significant, at a=0.01, for the patients of group A (classic CVCs) mainly because of the insufficient flow rate of the PICCs when compared with the CVCs and especially if one considers the fact that the physicians did not have any experience with the PICC method at all. CONCLUSIONS: PICCs under ultrasound guidance constitute the solution of choice for patients and they definitely surpass the CVCs focusing mainly on the improvement of the quality of life and the satisfaction of patients.
