Abstract
The acrofacial dysostosis (AFD) syndromes are an heterogeneous group of disorders with undefined classification and inheritance. We report the sonographic and clinical features of an AFD fetus with predominantly pre-axial forms. We made a prenatal diagnosis of Nager syndrome but postnatal examination showed post-axial defects previously undetectable by ultrasound.

Abstract
Based on the degree of cytologic atypia, mitotic activity, and other features, uterine smooth muscle tumors have historically been grouped into two classes: benign leiomyomas and malignant leiomyosarcomas. However, this separation holds true more in principle than in practice because the tumor's biological potential may not always be determined with certainty, complicating diagnosis, and therapy. We report three cases of patients with uterine smooth muscle tumors of uncertain malignant potential. Surgery was radical in two and conservative in one. During the follow-up, one patient developed diffuse lung metastases. The two other patients have not shown any signs of relapse to date. Uterine smooth muscle tumors of uncertain malignant potential may have an unpredictable clinical course and may metastasize to seemingly low-grade neoplasms in distant sites even after several years and even in the absence of important negative prognostic predictors, such as coagulative tumor cell necrosis. At present, no final consensus has been reached on the choice of the best strategy for surgery and adjuvant therapy

Abstract
Several investigators have reported the presence of biomechanical, kinematic, anatomic, fiber orientation patterns and biological differences between the anteromedial bundle and the posterolateral bundle of ACL. The purpose of this prospective randomized study was to compare the clinical, instrumental and X-ray outcome of two ACL reconstruction techniques with hamstring tendons: one with a single intra-articular bundle associated to an extra-articular sling, the second with a more anatomic double-bundle technique that reproduces better the native ACL function. From an initial group of 100 patients who underwent ACL reconstruction, 72 patients (35 single bundle plus lateral plasty and 37 double bundle) were evaluated with IKDC, Tegner score, KT2000 arthrometer, Activity Rating Scale, Psychovitality Questionnaire and Ahlback radiographic score at a mean 3 years follow-up. Double-bundle group showed significantly better results regarding IKDC, ROM, Activity Rating Scale and time to return to sport. Also KT 2000 showed significant differences in objective stability. The double-bundle technique for ACL reconstruction described in this paper has demonstrated significantly better subjective, objective and functional results compared with a double-stranded hamstrings plus extra-articular sling at a minimum 3-year follow-up.

Abstract
BACKGROUND An unusual histologic finding in tissue obtained from voluntary pregnancy termination (VPT) is reported to demonstrate the utility of pathologic examination of this specimen. METHODS A 30-year-old woman with a history of depression was referred to the gynecology clinic for VPT in the eighth week of gestation. Material obtained from uterine cavity curettage was macroscopically and histologically examined. Based on the histological findings, a molecular study by polymerase chain reaction amplification (PCR) was performed to evaluate the presence of human papilloma virus (HPV) DNA. For DNA extraction, 4-microm-thick histological sections were stained with hematoxylin and examined under a stereomicroscope. The PCR amplification was performed with the L1 consensus primers Gp5+/Gp6+, giving an expected PCR product size of 150 bp: these primers have been developed to allow the detection of a broad spectrum of mucosotropic HPV genotypes. RESULTS Histological examination of tissue obtained from the VPT showed immature villi with post-abortive hydropic degeneration and the presence of a small fragment of cervical mucosa with a squamous intraepithelial lesion characterized by mild to moderate nuclear atypia (SIL). PCR revealed that this lesion was related to HPV. Subsequently, the pap smear and cervical biopsy revealed a high-risk squamous intraepithelial lesion due to high-risk HPV. CONCLUSIONS This report demonstrates that tissue obtained from VPT cannot be considered normal "a priori" and that a histological study can be useful to provide new information regarding a woman's gynecological health.

Abstract
In mouse cerebellar granule neurons (CGNs) the marine neurotoxin domoic acid (DomA) induces neuronal cell death, either by apoptosis or by necrosis, depending on its concentration, with apoptotic damage predominating in response to low concentrations (100 nM). DomA-induced apoptosis is due to selective activation of AMPA/kainate receptors, and is mediated by DomA-induced oxidative stress, leading to mitochondrial dysfunction and activation of caspase-3. The p38 MAP kinase and the c-Jun NH2-terminal protein kinase (JNK) have been shown to be preferentially activated by oxidative stress. Here we report that DomA increases p38 MAP kinase and JNK phosphorylation, and that this effect is more pronounced in CGNs from Gclm (-/-) mice, which lack the modifier subunit of glutamate-cysteine ligase, have very low glutathione (GSH) levels, and are more sensitive to DomA-induced apoptosis than CGNs from wild-type mice. The increased phosphorylation of JNK and p38 kinase was paralleled by a decreased phosphorylation of Erk 1/2. The AMPA/kainate receptor antagonist NBQX, but not the NMDA receptor antagonist MK-801, prevents DomA-induced activation of p38 and JNK kinases. Several antioxidants (GSH ethyl ester, catalase and phenylbutylnitrone) also prevent DomA-induced phosphorylation of JNK and p38 MAP kinases. Inhibitors of p38 (SB203580) and of JNK (SP600125) antagonize DomA-induced apoptosis. These results indicate the importance of oxidative stress-activated JNK and p38 MAP kinase pathways in DomA-induced apoptosis in CGNs.

Abstract
PURPOSE OF THE STUDY There have been few prospective studies comparing minimally invasive approaches for total hip replacement. We wanted to ascertain the contribution of the minimally invasive posterior approach in comparison with the standard posterolateral approach in terms of early outcome. MATERIALS AND METHODS This was prospective comparative consecutive series of patients. Patients with major architectural problems or undergoing revision arthroplasty were excluded. One hundred ten patients (116 hips) were divided into two groups which were comparable for number of patients, gender, age, body mass index, indication for surgery, and preoperative function scores. The preoperative ASA score was lower in the minimally invasive group (p=0.04). The patients were in the lateral reclining position for the two approaches and classical instrumentation using the same implants (stems and cemented or non-cemented cups) were used. We noted operative time and blood loss (using the Brecher method based on the hematocrit at day 1 and 5 and the number of blood transfusions), postoperative pain, and implant position. Functional outcome was assessed with the modified Harris score and the WOMAC index (at 6 weeks and 3 and 6 months). Statview(R) was used to search for statistical significance considering p<0.05 as significant. RESULTS Mean length of incision was 8.5 cm versus 15.1 cm. Mean blood loss was significantly less in the minimally invasive group (p=0.027) as was the level of postoperative pain as confirmed by the lesser consumption of morphine analgesics (p=0.006). Other operative variables as well as implant position were comparable. There were no major complications in the minimally invasive group. In the standard group, there was one case of common peroneal nerve palsy, two dislocations, and two fractures related to falls after prosthesis implantation. The WOMAC index was better after the minimally invasive approach at six weeks and at three months (p<0.05). The modified Harris score was better only at six weeks. Functional outcome and pain became comparable thereafter. DISCUSSION AND CONCLUSION The minimally invasive posterior approach does not require an orthopedic table nor specific instrumentation. A minute procedure is required with ligature of the posteromedial circumflex artery of the thigh to improve exposure and limit intraoperative bleeding. It enables satisfactory reproducible implant positioning. Conversion to an open posterolateral approach is possible if needed. The minimally invasive posterior approach enables a reduction in intraoperative bleeding and in postoperative pain while allowing earlier more rapid rehabilitation. Early clinical outcome is better but beyond six weeks, the functional results are comparable for the two approaches. The minimally invasive posterior approach is a reliable reproducible approach with a progressive learning curve.

Abstract
The incidence and prognostic relevance of bone marrow (BM) and leukapheresis (PBPC) tumor cell contamination (TCC) in breast cancer patients is still to be circumstantiated. We developed a new comprehensive gene expression panel to study cytokeratins (CK), maspin (MAS) and mammaglobin (MAM) as possible predictors of prognosis. Forty-eight patients undergoing high dose chemotherapy (HDCT) and PBPC support were enrolled and analyzed for TCC on 116 PBPC apheresis and 96 BM obtained at basal conditions. All of the patients were evaluated by reverse transcriptase nested PCR (RT-PCR) for MAM and MAS gene expression and by immunocytochemistry (ICC) and nested RT-PCR to evaluate CK expression. PBPC and BM frequency of CK-positive (+) cells was 12-13% by ICC and 71-73% by RT-PCR respectively. Sixty-seven percent of CK ICC+ samples were MAM RT-PCR+ and 89% of them were MAS RT-PCR+. PBPC and BM frequency of MAM+ cells was 21% and 31% respectively, while for MAS+ cells it was 48% and 52% respectively by RT-PCR. After 71 mo median FU, 16 patients (33%) relapsed and 14 (88%) had BM/PBPC TCC. No marker had an impact on overall survival (OS) but MAS expression on BM and MAM expression on PBPC correlated with a statistically significant improved (p=0.05) and worsened RFS (p=0.06) respectively. These data confirm the activity of MAM as a negative prognostic factor and show for the first time that MAS could work as a tumor suppressor gene even in a clinical setting, since it protects from recurrence.

Abstract
We report a family affected to the fourth generation by uncombable hair syndrome. This syndrome is characterized by unruly, dry, blond hair with a tangled appearance. The family pedigree strongly supports the hypothesis of autosomal dominant inheritance; some members of the family had, apart from uncombable hair, minor signs of atopy and ectodermal dysplasia, such as abnormalities of the nails. The diagnosis was confirmed by means of extensive scanning electron microscopy. A trial with oral biotin 5 mg/day was started on two young patients with excellent results as regards the hair appearance, although scanning electron microscopy did not show structural changes in the hair. After a 2-year-period of follow-up, hair normality was maintained without biotin, while nail fragility still required biotin supplementation for control.

Abstract
PURPOSE Radiofrequency ablation uses the thermal energy produced by a generator to create a coagulative necrosis. The method is well established for the treatment of a variety of primary and secondary cancers of the liver but is less well studied for the treatment of lung malignancies. MATERIALS AND METHODS From March 2005 to March 2006, 11 patients (seven men and four women) with single or multiple pulmonary nodules underwent radiofrequency ablation of 12 unresectable pulmonary tumours. Follow-up computed tomography (CT) was performed at 1, 3, 6, and 12 months after radiofrequency ablation. Lesions were evaluated for dimensions and contrast enhancement. RESULTS Radiofrequency ablation was well tolerated by all patients. Postprocedural complications included four cases of pneumothorax treated with simple aspiration without tube placement and one case of small parenchymal haemorrhage. There were no major complications. CONCLUSIONS Radiofrequency ablation of primary or secondary pulmonary lesions is a safe and technically feasible option for the management of unresectable pulmonary malignancies.
