Introduction: Acquired megalourethra (AMU) after repair of proximal hypospadias can be a serious complication. An observational retrospective study of its incidence among different types of repair was performed. Materials and methods: Clinical charts of patients operated on for proximal hypospadias were reviewed. Inclusion criteria: all primary hypospadias operated in 1991-2004, with the meatus positioned in proximal penile, scrotal or perineal position. Results: Of 770 hypospadias cases treated, 130 (16%) were proximal. Seventy-two patients (55%) were treated using preputial flaps: 36 with a tubularized preputial island flap (TIF) and 36 an onlay island flap (OIF). Fifty-eight patients (45%) underwent staged repairs: Belt-Fuquà (BF) in 18 and Bracka procedure in 40 cases. After a mean follow up of 16 years (range 6-19) the overall incidence of complications for each technique was: TIF 36%; OIF 33%; BF 25%; two-stage Bracka 7.5%. The most common complication encountered was neo-urethral fistula. AMU occurred in only 5 cases, none with associated distal urethral stenosis, all in the TIF and OIF groups, and all successfully treated by reduction re-do urethroplasty. Conclusion: A very small number of the patients operated using preputial island flaps techniques developed AMU. None of the staged repairs developed AMU, and this is the preferred choice in proximal hypospadias when the urethral plate requires division and/or substitution. All cases of AMU resolved after urethral tapering. © 2012 Journal of Pediatric Urology Company. Published by Elsevier Ltd. All rights reserved.

A 14-year-old girl stated that she has vulvar pruritus, pain, and bleeding and underwent a complete gynecological evaluation during which a suspicious 2-cm achromic lesion on her vulva was observed. Initially, it was suspected to be a pyogenic granuloma, in relation to the patient's age. A biopsy was taken, and a histopathological diagnosis of amelanotic mucosal melanoma was made. Pyogenic granuloma is a reactive hyperproliferation vascular response to trauma or other stimuli. It predominantly occurs in the second decade of life in young females, in relation to the vascular effects of female hormones. Primary mucosal melanoma is a rare and aggressive neoplasm, characterized by a higher aggressiveness and a worse prognosis than her cutaneous counterpart. The female genital tract is the second most common site of onset of mucosal melanoma; it represents the 3% of melanomas diagnosed in women. © 2015 Wolters Kluwer Health, Inc.

Bladder masses are represented by either benign or malignant entities. Malignant bladder tumors are frequent causes of disease and death in western countries. However, in children they are less common. Additionally, different features are found in childhood, in which non epithelial tumors are more common than epithelial ones. Rhabdomyosarcoma is the most common pediatric bladder tumor, but many other types of lesions may be found, such as malignant rhabdoid tumor (MRT), inflammatory myofibroblastic tumor and neuroblastoma. Other rarer tumors described in literature include urothelial carcinoma and other epithelial neoplasms. Rhabdomyosarcoma is associated to a variety of genetic syndromes and many genes are involved in tumor development. PAX3-FKHR and PAX7-FKHR (P-F) fusion state has important implications in the pathogenesis and biology of RMS, and different genes alterations are involved in the pathogenesis of P-F negative and embryonal RMS, which are the subsets of tumors most frequently affecting the bladder. These genes include p53, MEF2, MYOG, Ptch1, Gli1, Gli3, Myf5, MyoD1, NF1, NRAS, KRAS, HRAS, FGFR4, PIK3CA, CTNNB1, FBXW7, IGF1R, PDGFRA, ERBB2/4, MET, BCOR. Malignant rhabdoid tumor (MRT) usually shows SMARCB1/INI1 alterations. Anaplastic lymphoma kinase (ALK) gene translocations are the most frequently associated alterations in inflammatory myofibroblastic tumor (IMT). Few genes alterations in urothelial neoplasms have been reported in the paediatric population, which are mainly related to deletion of p16/lnk4, overexpression of CK20 and overexpression of p53. Here, we reviewed available literature to identify genes associated to bladder malignancies in children and discussed their possible relationships with these tumors. © 2016 Bentham Science Publishers.

A pectoralis major myofascial flap (PMMF) is a simple variant of the pectoralis major myocutaneous flap (PMMC), and allows avoiding some of the disadvantages of Ariyan's technique while reducing well-known, overall complications. This is a retrospective analysis of 45 hypopharyngeal reconstructions (40 immediate reconstructions after subtotal pharyngolaryngectomy and 5 performed during revision surgery) using PMMF flap, performed from February 1995 to February 2008 in the Department of Otolaryngology at the "San Camillo-Forlanini" Hospitals in Rome, in collaboration with the Department of Plastic Surgery. In our series, we observed postoperative flap-related complications in 6.7% of cases. The incidence of major flap complications requiring surgical revision was 2.2%. Two minor complications were seen: hypopharyngeal stenosis and a salivary fistula, both of which were managed without surgery. Total or partial necrosis did not occur in any case. There were four postoperative deaths, but which were not related to flap complications in any case. In the remaining cases, oesophageal X-ray imaging showed the absence of fistulas and adequate calibre of the reconstructed tract; oral intake started within postoperative day 10-12, without swallowing problems of liquid or solid food. Postoperative radiotherapy performed in 30 patients was well tolerated. The PMMF flap is safe one-step procedure with low morbidity that is particularly useful for partial hypopharyngeal reconstructions, overcoming the disadvantages of the PMMC flap and offering comparable results to fasciocutaneous free flaps.

Radioactive 90Y-selective internal radiation (SIR) sphere therapy is increasingly used for the treatment of nonresectable hepatocellular carcinoma (HCC). However, the maximum delivered dose is limited by severe injury to the nontarget tissue, including liver parenchyma. Our study aimed to implement radiobiologic models for both tumor control probability (TCP) and normal-tissue complication probability (NTCP) to describe more effectively local response and the liver toxicity rate, respectively. Methods: Patients with documented HCC, adequate bone marrow parameters, and regular hepatic and pulmonary function were eligible for the study. Patients who had pulmonary shunt greater than 20% of 99mTc-labeled macroaggregated albumin or any uncorrectable delivery to the gastrointestinal tract, reverse blood flow out of the liver, or complete portal vein thrombosis were excluded. Patients received a planned activity of the 90Y-SIR spheres, determined using the empiric body surface area method. The dose distribution was determined using posttreatment (3-dimensional) activity distribution and Monte Carlo dose voxel kernel calculations, and the mean doses to healthy liver and tumor were calculated for each patient. Response was defined according to Response Evaluation Criteria in Solid Tumors (RECIST) and recommendations of the European Association for the Study of the Liver (EASL). Criteria were used to assess possible liver toxicities. The parameters of TCP and NTCP models were established by direct maximization of the likelihood. Results: Seventy-three patients were treated. With an average dose of 110 Gy to the tumor, complete or partial response was observed in 74% and 55% of patients according to the EASL guideline and RECIST, respectively, and the predicted TCPs were 73% and 55%, respectively. With a median liver dose of 36 Gy (range, 6-78 Gy), the ≥grade 2 (G2), ≥grade 3 (G3), and ≥grade 4 (G4) liver toxicities were observed in 32% (23/73), 21% (15/73), and 11% (8/73) of patients, respectively. The parameters describing the ≥G2 liver toxicity data using the NTCP model were a tolerance dose of the whole organ leading to a 50% complication probability of 52 Gy (95% confidence interval, 44-61 Gy) and a slope of NTCP versus dose of 0.28 (95% confidence interval, 0.18-0.60), assuming n = 1. Conclusion: The radiobiologic approach, based on patient-specific dosimetry, could improve the 90Y-microsphere therapeutic approach of HCC, maintaining an acceptable liver toxicity.

Musculoskeletal diseases are the most frequent cause of pain in the working population. Rheumatic diseases are chronic illnesses, cause of functional impairment, relevant working disability and absence from work; however, affected patients maintain a significant functional ability. In this context, the "Fit for work" project, operating in Italy since 2012, promotes the management of chronic musculoskeletal conditions through the realization, also in our country, of a rheumatic medical assistance network in behalf of workers affected by rheumatic diseases and other musculoskeletal disabiliting conditions.

Introduction: To investigate the performance of combined 18F-FDG-PET/CT as a predictor of the WHO-classification based malignancy grade in thymic epithelial tumors. Methods: From 05/06 to 02/12, the data of 47 patients with thymic epithelial tumors assessed by 18F-FDG-PET/CT before being surgically treated were collected in 3 centers and retrospectively reviewed for the purposes of this study. The SUVmax and the SUVmax/T index (the ratio tumor-SUVmax to tumor-size) have been matched with specific subgroups of the WHO-classification: low-risk thymomas (types A-AB-B1), high-risk thymomas (types B2-B3) and thymic carcinomas (type C). Results: There were 22 men and 25 women (age range: 31-84 yrs). Mean tumor size was 44.7 ± 19.0. mm. The WHO-classification was: type-A #2, type-AB #11, type-B1 #9, type-B2 #9, type-B3 #9 and type-C #7. The SUVmax and the SUVmax/T were found to be predictive factors useful to distinguish thymomas from thymic carcinomas (SUVmax: area under ROC-curve: 0.955, p= 0.0045; SUVmax/T-size: area under ROC-curve: 0.927, p= 0.0022). Moreover, both parameters were found to be correlated with the WHO malignancy grade (low-risk thymomas; high-risk thymomas; thymic carcinoma), Spearman correlation coefficients being 0.56 (p< 0.0001) and 0.76 (p< 0.0001), respectively for the SUVmax and for the SUVmax/T index. In addition, the SUVmax is also significantly correlated with Masaoka stage (Spearman correlation coefficient: 0.30, p= 0.0436). Conclusions: A significant relationship was observed between 18F-FDG-PET/CT findings and histologic WHO-classification for this cohort of thymic epithelial tumors. Thus, on the basis of these evidences, we infer that 18F-FDG-PET/CT may be useful to predict histology and the WHO classes of risk. © 2013 Elsevier Ireland Ltd.

We present a retrospective study investigating the results of the subjective assessment of displaced intra-articular calcaneal fractures in a selected cohort of 42 patients treated operatively, with a follow-up duration of at least 3 years. The adjusted American Orthopaedic Foot and Ankle Society questionnaire, Foot Function Index, and visual analog scale were used to quantify the subjective evaluations. Our hypothesis was that good subjective results could be predicted and obtained in patients with specific characteristics if anatomic reduction of the fracture was achieved. The results of the study confirmed our hypothesis. A number of specific subgroup analyses were undertaken. The study confirmed that Böhler angle restoration and the quality of reduction of the subtalar joint facet are important prognostic factors related to the outcome. In contrast, gender and Sanders type had less influence at the intermediate-term follow-up results. The main weaknesses of the present study included its retrospective nature, the lack of a control group managed nonoperatively for comparison, and the small sample size. Moreover, the operating surgeon performed the radiographic measurement and categorized the quality of the surgical reconstruction. © 2012 American College of Foot and Ankle Surgeons.

OBJECTIVES: Wide surgical excision with tumour-free margins is the mainstay of therapy for primary chest wall chondrosarcoma (PCWC). Few studies on treatment outcome and prognostic factors of PCWC requiring chest wall resection are available. We analysed our experience on surgical treatment of PCWC with emphasis on survival and recurrence prognostic factors. METHODS: From 1986 to 2012, 89 patients (65.2% males, median age 55 years) with PCWC were operated on. The median tumour maximum diameter was 7 cm (range 2-30 cm). RESULTS: We performed 23 sternectomies and 66 lateral chest wall resections (median ribs resected: 2; range 1-7). Resections were extended to lung (n = 19), diaphragm (n = 13), vertebral body (n = 6) or clavicle (n = 1). Negative margins were obtained in 85.4% of cases. Chest wall reconstruction was obtained mainly by prosthetic non-rigid or rigid materials and muscle flap coverage. In the last years, 3 patients received a sternal replacement with cadaveric allograft, and 2 had a chest wall reconstruction with titanium bars and 17 with a rib-like prosthesis. Perioperative mortality and morbidity rates were 0 and 12.4%, and 5- and 10-year overall and disease-free (on R0 resections) survival rates were 67.1 and 57.8%, and 70 and 52%, respectively. A favourable outcome (univariate analysis) was seen for G1 tumours (P < 0.0001), negative surgical margins (P < 0.0001), age ≤55 years (P = 0.005), no adjuvant treatment (P < 0.001) and diameter ≤6 cm (P = 0.005). Independent predictors of better survival (multivariate analysis) were negative surgical margins (P = 0.0001), G1 tumours (P = 0.02), age ≤55 years (P = 0.006) and diameter ≤6 cm (P = 0.006). A predictive risk factor for recurrence was histological grade. CONCLUSIONS: Surgical resection of PCWC leads to good oncological outcome. Wide surgical margins and G1 tumours predicted a better prognosis and a lower recurrence rate. The evolution of surgical technique and the introduction in clinical practice of new prosthetic materials allowed larger resections, and safe and anatomical reconstruction. © The Author 2014.

Purpose: 153Sm-ethylene diamine tetramethylene phosphonic acid (153Sm-EDTMP) is widely used to palliate pain from bone metastases, and is being studied for combination therapy beyond palliation. Conceptually, red marrow (RM) dosimetry allows myelotoxicity to be predicted, but the correlation is poor due to dosimetric uncertainty, individual sensitivity and biological effects from previous treatments. According to EANM guidelines, basic dosimetric procedures have been studied to improve the correlation between dosimetry and myelotoxicity in 153Sm-EDTMP therapy. Methods: RM dosimetry for 33 treatments of bone metastases from breast, prostate and lung tumours was performed prospectively (with 99mTc-MDP) and retrospectively, acquiring whole-body scans early and late after injection. The 153Sm-EDTMP activity was calculated by prospective dosimetry based on measured skeletal uptake and full physical retention, with the RM absorbed dose not exceeding 3.8 Gy. Patient-specific RM mass was evaluated by scaling in terms of body weight (BW), lean body mass (LBM) and trabecular volume (TV) estimated from CT scans of the L2-L4 vertebrae. Correlations with toxicity were determined in a selected subgroup of 27 patients, in which a better correlation between dosimetry and myelotoxicity was expected. Results: Skeletal uptakes of 99mTc and 153Sm (Tc% and Sm%) were well correlated. The median Sm% was higher in prostate cancer (75.3 %) than in lung (60.5 %, p =0.005) or breast (60.8 %, p =0.008). PLT and WBC nadirs were not correlated with administered activity, but were weakly correlated with uncorrected RM absorbed doses, and the correlation improved after rescaling in terms of BW, LBM and TV. Most patients showed transient toxicity (grade 1-3), which completely and spontaneously recovered over a few days. Using TV, RM absorbed dose was in the range 2-5 Gy, with a median of 312 cGy for PLTin patients with toxicity and 247 cGy in those with no toxicity (p =0.019), and 312 cGy for WBC in those with toxicity and 232 cGy in those with no toxicity (p = 0.019). ROC curves confirmed the correlations, yielding toxicity absorbed dose thresholds of 265 cGy for PLT and 232 cGy for WBC. Conclusion: The best predictor of myelotoxicity and blood cells nadir was obtained scaling the RM absorbed dose in terms of the estimated TV. It seems clear that the increase in skeletal uptake due to the presence of bone metastases and the assumption of full physical retention cause an overestimation of the RM absorbed dose. Nevertheless, an improvement of the dose-toxicity correlation is easily achievable by simple methods, also leading to possible improvement in multifactorial analyses of myelotoxicity. © Springer-Verlag Berlin Heidelberg 2013.
