Abstract
BACKGROUND Hereditary tyrosinemia type 1 (HT1) is characterized by severe progressive liver disease and renal tubular dysfunction. NTBC therapy has revolutionized the management of HT1 but its effect on renal tubular function has so far been poorly investigated. The aim of this study was to describe the early effect of NTBC on renal tubular disease in patients with HT1. METHODS Five HT1 patients (age between 5 and 53 months) with different types of presentation were evaluated before and during the first 2 weeks of therapy with NTBC in a retrospective case analysis for phosphate metabolism and renal tubular function. RESULTS Before starting NTBC therapy, all children manifested signs of renal dysfunction which included hypophosphatemia, acidosis, reduced phosphate reabsorption, aminoaciduria, glycosuria (Fanconi syndrome), and variable degree of proteinuria. Some patients also presented increased urinary calcium/creatinine ratio and raised fractional excretion of sodium. Starting of NTBC therapy resulted in the rapid normalization of plasma phosphate within one week from its initiation in majority of patients and in all patients during the second week of therapy. TmP/GFR normalized in 48h, while the other markers of renal dysfunction showed an improving trend over 2 weeks. CONCLUSIONS NTBC is an efficient treatment for renal tubular dysfunction in HT1, allowing the return to normal function within a few weeks. Its early effect on renal tubular cells appeared to be very rapid, particularly in normalizing plasma phosphate and TmP/GFR. In our series of patients, the TmP/GFR resulted as the most reliable index of tubular function.

Abstract
Spindle cell transformation or metaplasia has been so far demonstrated in the context of both benign and malignant conditions. Spindle cell lesions of the thyroid gland of either primary or secondary origin to metastatic disease represent rare entities. We describe two patients with papillary thyroid carcinoma (PTC) showing spindle cell metaplasia, submitted to thyroidectomy due to euthyroid bilateral nodular thyroid disease. Cytological examination of fine-needle aspiration biopsy performed in the dominant nodules was consistent with follicular neoplasm in one case and with a hyperplastic/adenomatous nodule in the other patient. Histological examination disclosed unencapsulated follicular variant of PTC with spindle cell metaplasia in either cases. Both patients are doing well without clinical or laboratory evidence of PTC recurrence at 3- and 1-year follow-up, respectively. We present the clinical, pathological, and immunohistochemical aspects of these unusual cases and thoroughly discuss the differential diagnosis with other spindle cell lesions of the thyroid gland.

Abstract
BACKGROUND/AIM Von Recklinghausen disease is a syndrome characterized by a wide phenotypic variability giving rise to both, cutaneous and visceral benign and malignant neoplasms. The first include cutaneous neurofibromas, subcutaneous and plexiform neurofibromas. The latter can undergo malignant transformation and/or determine elephantiasis neuromatosa. Visceral tumors may include malignant peripheral nerve sheet tumors, gastrointestinal stromal tumors, cerebral gliomas and abdominal neurofibromas. In the present study, the authors discuss the clinical and biomolecular characterization of a cohort of 20 families with a diagnosis of type 1 neurofibromatosis. PATIENTS AND METHODS Clinically, the cohort includes three probands with elephantiasis neuromatosa and a peculiarly high incidence of breast and gastrointestinal cancer. RESULTS Among the 14 NF1 mutations documented, 10 encoding for a truncated protein have been associated to particularly aggressive clinical phenotypes including elephantiasis neuromatosa, malignant peripheral nerve sheet tumors, breast cancer, gastrointestinal stromal tumors. CONCLUSION This effect on protein synthesis, rather than the type of NF1 mutation, is the key to the explanation of the genotype-phenotype correlations in the context of neurofibromatosis type 1.

Abstract
INTRODUCTION Micro-RNA, a new class of small, non-coding RNAs, have been shown to be deregulated in several human carcinomas. In particular, SNP rs2910164 in pre-miR146a appears to be correlated with papillary thyroid carcinoma and may be involved in its genetic predisposition. Since data on follicular thyroid carcinomas (FTC) are lacking, we evaluated the involvement of SNP rs2910164 in FTC. METHODS Thirty-nine cases of FTC and 20 follicular adenomas, defined according to WHO criteria, were selected. DNA and RNA were extracted from formalin-fixed paraffin-embedded blocks of both neoplastic and non-neoplastic areas. The DNA region of pre-miR146a, containing SNP rs2910164, was sequenced. Total RNA including miRNAs was used for stem-loop RT reactions, and applying a standard TaqMan PCR kit protocol for real-time PCR. Wilcoxon signed-rank test and Friedman test were used for statistical analyses. RESULTS In 31% of FTC, the G allele was observed in neoplastic tissues, compared with the non-neoplastic areas (p < 0.05), whereas the CC phenotype was completely absent in tumours. Moreover, the expression of pre-miR146a was found to be significantly down-regulated in neoplastic tissues from FTC cases (p = 0.043), although no significant differences were seen in follicular thyroid adenomas. DISCUSSION The expression profile of pre-miR146a can be correlated with FTC tumourigenesis. The G allele in SNP rs2910164 appears to be correlated with the transition from normal to neoplastic tissue. The GG and GC alleles appear to be associated with an increased risk for FTC, while the CC allele seems to play a protective role.

Abstract
Uterine fibroids are the most common benign tumors of the female genital tract. The management of symptomatic fibroids has traditionally been surgical; however, alternative pharmacological approaches have been proposed to control symptoms. To date, gonadotropin-releasing hormone analogs are the only available drugs for the preoperative treatment of fibroids. However, the US Food and Drug Administration recently authorized ulipristal acetate (UPA), an oral selective progesterone-receptor modulator, for the same indication. UPA is a new, effective, and well-tolerated option for the preoperative treatment of moderate and severe symptoms of uterine fibroids in women of reproductive age. According to clinical data, UPA shows several advantages: it is faster than leuprolide in reducing the fibroid-associated bleeding, it significantly improves hemoglobin and hematocrit levels in anemic patients, and it grants a significant reduction in the size of fibroids, which lasts for at least 6 months after the end of the treatment. Furthermore, UPA displays a better tolerability profile when compared to leuprolide; in fact, it keeps estradiol levels at mid follicular phase range, thereby reducing the incidence of hot flushes and exerting no impact on bone turnover. On the grounds of this evidence, the administration of 5 mg/day ulipristal acetate for 3 months is suggested for different patient categories and allows for planning a treatment strategy tailored to meet an individual patient's needs.

Abstract
Pregnancy, the implantation of a fertilized ovum outside the endometrial cavity, occurs in 1.5%-2% of pregnancies. It is one of the major causes (about 6%) of maternal death during the first trimester of pregnancy. The remaining 5% implant in the ovary, peritoneal cavity, within the cervix, and the omental pregnancy is the least common form of abdominal pregnancies. A review of the literature on Medline for the period 1958-2012 reported only 16 cases of omental pregnancy. Here we report a case of primary omental pregnancy in a nulliparous woman. A 24 year-old woman gravid 1, para 0, with lower abdominal pain. Her last menstrual period occurred 8 weeks before the visit. The physical examination revealed abdominal tenderness in the lower quadrants, she was not bleeding. Transvaginal ultrasound showed: a free anechoic/hypoechoic area of 30 x 57 mm in the pouch of Douglas and the endometrium was homogeneus with a thickness of 12 mm and no evidence of gestational sac in the uterine cavity. Laboratory data revealed a normal cell blood count and beta hcg levels of 8047 IU / L. Because of continuing abdominal pain and a diagnosis of ectopic pregnancy a diagnostic laparoscopy was performed, which showed hemoperitoneum. Further inspection of abdominal cavity revealed a bloody lesion that was tenaciously adherent to the omentum, using non traumatic laparoscopic forceps and bipolar scissors we carefully removed a friable mass of about 30 mm from the omental attachments. Histological examination showed the presence of blood clot material mixed with trophoblastic tissue. Ultrasound evaluation and and hCG assessment are important to determine the extrauterine location of the ectopic pregnancy but the early diagnosis of abdominal pregnancy requires also a laparoscopic evaluation and, as our case has highlighted, thorough abdominal exploration especially in the absence of adnexal findings when ectopic pregnancy is highly suspected. Early diagnosis of omental pregnancy is difficult but essential to reduce the high mortality risk for the mother.

Abstract
Granular cell tumor (GCT) is a rare and usually benign lesion of neural / schwannian origin, most frequently found in middle-age women. The appendicular involvement is extremely rare: in over half a century only twelve cases have been reported in the literature, the patients living in America and Europe. Hitherto, no cases are documented from Africa, Asia and Oceania and no cases of malignant GCTs of the appendix have been reported. Most patients were diagnosed preoperatively as having acute appendicitis, whereas in three patients the tumor was incidentally detected during major abdominal surgery. The GCTs were equally distributed between mid-appendix and tip, where lymphoid tissue is more abundant and the anatomical nerve supply is progressively reduced. Moreover, the appendix surrounding the GCTs is characterized by the presence of chronic inflammatory cells (histiocytes, plasmocytes, eosinophils, mastocytes) and, therefore, a chronic inflammation of the appendix may be an antecedent condition favouring the appearance of GCTs. The GCT of the appendix appears so to be a lesion that reflects local reactive changes in the neural / schwannian cells, rather than being a genuine neoplasm. We describe the smallest GCT of the appendix ever reported, with a detailed literature review supporting its reactive origin in the lymphatic tissue-rich sites, such as ileo cecal appendix.

Abstract
STUDY OBJECTIVE To compare single-incision mini-slings (SIMSs) and retropubic tension-free vaginal tape (r-TVT) in terms of the long-term efficacy and safety for the treatment of female stress (SUI) or mixed urinary incontinence (MUI). DESIGN Prospective multicenter cohort trial (registration number NCT00751088) (Canadian Task Force II). SETTINGS Department of Obstetrics and Gynecology, Italy. PATIENTS Two hundred-forty women with SUI/MUI. INTERVENTIONS SIMS or r-TVT. MEASUREMENTS AND MAIN RESULTS The operative time and the use of analgesic tablets were significantly (p < .001) higher and lower, respectively, in the r-TVT group versus the SIMS group. After 24 months of follow-up, no difference between the study arms was observed in terms of the complication rate (30/120 [25%] vs 19/120 [15.8%] for the r-TVT and SIMS arms, respectively; relative risk = 1.58; 95% confidence interval, 0.94-2.65; p = .083), whereas the subjective cure rate was significantly lower in the SIMS arm than in the r-TVT arm (57/103 [55.3%] vs 89/106 [84.0%] for the r-TVT and SIMS arms, respectively; relative risk = 0.66; 95% confidence interval, 0.54-0.80]; p < .001). The proportion of retreated patients for SUI/MUI was significantly higher in the SIMS arm than in the r-TVT arm (37/103 [34.9%] vs 12/106 [11.3%] for SIMS and r-TVT arm, respectively; p < .001). CONCLUSION SIMS has no advantage in terms of safety over r-TVT and was found to be less effective than r-TVT. Thus, its use in the clinical practice should be questioned.

Abstract
BACKGROUND Shear stress triggers conformational stretching of von Willebrand factor (VWF), which is responsible for its self-association and binding to the platelet receptor glycoprotein (GP)Ibα. This phenomenon supports primary hemostasis under flow. Type 2B VWF natural mutants are considered to have increased affinity for platelet GPIbα. OBJECTIVES To assess the mechanism responsible for the enhanced interaction of the p.R1306W VWF mutant with the platelet receptor. METHODS The interaction of GPIbα with wild-type (WT) and p.R1306W VWF multimers and A1-A2-A3 constructs was investigated with surface plasmon resonance spectroscopy. Analysis of the static VWF conformation in solution was performed with dynamic light scattering spectroscopy. The shear stress-induced self-association of VWF multimers was investigated with atomic force microscopy (AFM) over a 0-60 dyn cm(-2) range. RESULTS WT VWF did not interact with GPIbα under static conditions, whereas the mutant at ~ 2 μg mL(-1) already bound to the receptor. By contrast, the WT and p.R1306W-A1-A2-A3 constructs showed comparable affinities for GPIbα (Kd ~ 20 nm). The hydrodynamic diameter of resting R1306W VWF multimers was significantly greater than that of the wild type (210 ± 60 nm vs. 87 ± 22 nm). At shear forces of < 14 dyn cm(-2) , the p.R1306W multimers rapidly changed conformation, entering a regime of self-aggregation, which, in contrast, was induced for WT VWF by shear forces of > 30 dyn cm(-2) . Mechanical stretching AFM experiments showed that p.R1306W multimers needed less energy per length unit (~ 10 pN) to be stretched than the WT protein. CONCLUSIONS The increased affinity of p.R1306W VWF for GPIbα arises mostly from higher sensitivity to shear stress, which facilitates exposure of GPIbα binding sites.

Abstract
Xanthogranulomatous orchitis is an extremely rare inflammatory nonneoplastic lesion of the testis. We report a case of a 13-year-old adolescent boy who presented a painless left hemiscrotal swelling. The subsequent ultrasonography and magnetic resonance imaging revealed the presence of abnormal expanding tissue located in both testes and spermatic cord, reaching the internal inguinal ring. Testicular tumor markers were normal. The frozen section examination of the surgical specimen showed only inflammatory tissue and not neoplastic tissue. No orchiectomy was performed. Definitive histopathologic diagnosis was xanthogranulomatous inflammation. To our knowledge, this is the youngest case of xanthogranulomatous orchiepididymitis and funiculitis found in medical literature.

Abstract
Aspergillus fumigatus has become a leading cause of fungal morbidity and mortality, especially in immunocompromised patients. This fungus is able to grow as a multicellular community and produce a hydrophobic extracellular matrix (ECM), mainly composed of galactomannan and α-1,3 glucans, to protect itself from host defenses and antimicrobial drugs. This matrix envelops the fungus hyphae, binding them into a contiguous sheath on the colony surface, forming a biofilm and increasing the fungal resistance to adverse environmental factors. Adherence to host cells and resistance to physical removal play a key role in fungal colonization and invasion of the host and in a wide range of infections. Here we show that, by using atomic force spectroscopy, it is possible to exploit the peculiar hydrophobicity of the biofilm components (i.e., cell walls, ECM) to detect the biofilm spread, its growth, and lysis on rough surfaces. By means of this approach, we demonstrate that alginate lyase, an enzyme known to reduce negatively charged alginate levels in microbial biofilms, reduces the biofilm adhesion forces suggesting a loss of ECM from the biofilm, which could be used to enhance pharmacological treatments.

Abstract
AIM Our goals were to assess the psychometrical characteristics of EHP-30, to test its higher degree of appropriateness compared to the generic Quality of Life-assessment tools for Italian women suffering from endometriosis, and to determine its ability to identify the disease's effects on the patients' psychosocial condition, highlighting critical points that can be modified for future linguistic validation. METHODS Participants to our study were 98 women between 19 and 51-year-old (M=34.4, SD=7.5), selected from patients of the Department of Obstetrics and Gynecology, ARNAS Civico Hospital, Palermo, Italy. All of them had a surgical diagnosis of endometriosis with histological confirmation. Quality of Life was assessed through generic (SF-36) and specific (EHP-30) instruments. RESULTS Our study shows that the current Italian version of EHP-30 is affected by overall weaker construct validity than the English one; it seems that this has to be ascribed to the inadequacy of the EHP-30 translation into Italian. In particular, unsatisfactory reliability levels have been observed for social support and self-image scales. An incorrect order of response categories has been in addition found out for several items of the Italian version of EHP-30. Research results suggest solutions to adopt for a revision of the EHP-30 Italian version that can satisfy the requirements of validity and reliability. CONCLUSION Although requiring a structural and linguistic revision, also the Italian version of a specific measurement instrument as EHP-30 is, appears to be more appropriate than generic tools to assess the quality of life of Italian women suffering for endometriosis.

Abstract
OBJECTIVE The study reviews the endoscopic and histological features of human cytomegalovirus (HCMV) infections of the upper gastrointestinal (UGI) tract. MATERIALS AND METHODS Clinical histories, endoscopic findings and bioptic specimens of 30 cases of HCMV infection of the UGI tract, diagnosed in a University Hospital in a 10-year period, were reviewed. In all cases, viral inclusion bodies were detected in routine histopathological sections and the diagnosis was confirmed with immunohistochemistry. RESULTS Six patients were HIV+, whereas four had received organ transplantations, one was affected by common variable immunodeficiency and four had a recent history of malignancy. No other pathologic condition was evidenced in the remaining 15 cases. Mucosal alterations were endoscopically observed in the stomach (19 cases), esophagus (9), cardias (6) and duodenum (1), and multiple organs being synchronously affected in five patients (3 HIV+, 2 with history of malignancy). The antropyloric area was the most frequently affected site. Single ulcers were detected in 11 cases and multiple ulcers in 8, whereas mucosal thickenings (in the form of localized thickenings, polyps or rugal hypertrophy) were present in 13 patients. Thickenings of the mucosa were detected only in the stomach. At histology, necrotic material and granulation tissue were associated with moderate or marked lympho-plasmacytic infiltrate and foveolar hyperplasia in ulcerative lesions, whereas lesions labeled as mucosal thickenings showed mild or moderate chronic inflammatory infiltrate and foveolar hyperplasia. CONCLUSIONS Endoscopic manifestations of UGI tract involvement in HCMV infection are not specific, varying from erythematous mucosa to ulcers to mucosal thickenings.

Abstract
We report the case of a 70-year-old man with symptoms of urinary obstruction and haematuria, with histological diagnosis of primary signet-ring cell carcinoma of the prostate. Almost 90% of the tumour cells contained characteristic intracytoplasmic vacuoles that positively stained with diastase-digested PAS, Alcian blue and mucicarmine. The positive immunostaining for PSA and PSAP confirmed the prostatic origin of the tumour. Although the patient received hormonal therapy, the disease progressed and the patient died 11 months after surgery.

Abstract
Bronchogenic cyst is a congenital anomaly of the primitive foregut. Unusual occurrences in extrathoracic sites have been described in the literature, some of which may clinically simulate neoplasms. We report three additional cases arising near the left adrenal gland, left ovary and gastric wall. Pathological findings are discussed, together with a review of the literature.
