Abstract
Breast surgeons seem to agree on the fact that a same-day surgery (mastectomy and breast reconstruction) protocol provides appropriate cancer treatment during times of unprecedented resource limitations, such as in the COVID era. In this scenario, pre-pectoral implant-based breast reconstruction can be definitively considered a sustainable technique. Nevertheless, the authors focus on the management of patients who had already undergone a same day procedure with two-stage breast reconstruction, implanting a breast tissue expander during the last two-year period and have been progressively delayed according to a surgical care based on priority. We coined the expression “unhappy tissue expander” to define all those symptomatic patients for which surgery should not be delayed even during an epidemic context.

Abstract
Lymphovenous anastomosis (LVA) has been described as an effective treatment for early stages of lymphedema (LE). The aim of this study was to deepen the evaluation of the effectiveness of LVA by performing a meta-analysis to provide information about its utility in specific anatomical sites, clinical stages, duration of lymphedema, and surgical technique. A systematic literature search using PubMed/Medline, Google Scholar, and Cochrane Database was performed in November 2019. Only original studies in which exclusively LVA was performed for primary and/or secondary lymphedema in humans were eligible for data extraction. A meta-analysis was performed on articles with a well-defined endpoint and a subgroup analysis was conducted in relation to surgical technique, duration of lymphedema, stage of pathology. Forty-eight studies, including 6 clinical trials and 42 low-risk bias observational studies were included in our meta-analysis. 1,281 subjects were included and the majority of articles reported a pre-post analysis. Lymphaticovenular anastomosis appears to result effectively in treatment of lymphedema with an odds ratio of 0.07 (CI: 0.04, 0.13, p<0.001). All subgroup meta-analyses were statistically significant for LVAs specifically with regard to anatomical site, clinical stage, duration of LE, or type of microsurgical procedure (p<0.05).
Our meta-analysis confirmed the efficacy of LVAs for the treatment of lymphedema, even when subgroup analysis was performed for clinical stage, duration of pathology, anatomical site of lymphedema, or type of microsurgical procedure. Further prospective trials with a common clearly defined outcome measure are warranted for an unbiased evaluation.

Abstract
Volcanic emissions are a critical pathway in Earth's carbon cycle. Here, we show that aerial measurements of volcanic gases using unoccupied aerial systems (UAS) transform our ability to measure and monitor plumes remotely and to constrain global volatile fluxes from volcanoes. Combining multi-scale measurements from ground-based remote sensing, long-range aerial sampling, and satellites, we present comprehensive gas fluxes-3760 ± [600, 310] tons day-1 CO2 and 5150 ± [730, 340] tons day-1 SO2-for a strong yet previously uncharacterized volcanic emitter: Manam, Papua New Guinea. The CO2/ST ratio of 1.07 ± 0.06 suggests a modest slab sediment contribution to the sub-arc mantle. We find that aerial strategies reduce uncertainties associated with ground-based remote sensing of SO2 flux and enable near-real-time measurements of plume chemistry and carbon isotope composition. Our data emphasize the need to account for time averaging of temporal variability in volcanic gas emissions in global flux estimates.

Abstract
OBJECTIVE Current trends show a rise of attention given to breast cancer patients' quality of life and the surgical reconstructive result. Along with this trend, surgical training quality and efficacy are gaining importance and innovative training methods such as online videos shared on social media portals, are becoming main updating tools. In hazardous times like COVID-19 pandemic nowadays, online communication becomes of vital importance and adaptation and innovation are fundamental to keep research and education alive. The authors aimed to investigate the role of video and multimedia sources on the daily activity and surgical training of a representative group of surgeons specifically dedicated to oncologic, oncoplastic and reconstructive breast surgeries. MATERIALS AND METHODS A survey was produced and administered to 20 major Italian Breast Centers. Collected data were analyzed with Fisher's Exact Test. RESULTS From October 2019 to March 2020, a total of 320 surveys were collected. Among the responders, there were 188 trainees (intern medical doctors and residents) and 110 faculty, 72% of them belonged to a plastic surgery environment, while 28% to general surgery environment. Almost all respondents have ever watched videos concerning breast surgery. CONCLUSIONS The results of the study show how breast surgeons rely on videos and web platforms, mostly YouTube, when searching for training info about surgical procedures. Social media offer great opportunities for sharing knowledge and diffusion of new ideas but greater attention to their reliability is mandatory.

Abstract
BACKGROUND Immune markers in the peripheral blood of melanoma patients provide useful information for clinical management although there is poor consensus on circulating cells which could putatively reflect the disease activity and play a prognostic role. Here, we investigated both dendritic cells (DCs) and T-regulatory cells (Tregs). METHODS The number of DC subsets as myeloid (m) and plasmacytoid was measured by flowcytometry in 113 melanoma patients in different clinical stages and correlated with the disease activity to evaluate the recurrence free survival (RFS) calculated as difference between baseline and post-surgical values in relation to the criteria for the melanoma staging, as primary tumor removal, sentinel lymph node biopsy and completion of lymph node dissection. RESULTS Circulating mDC levels were significantly lower in metastatic melanoma than in other stages and inversely correlated to Treg values while both populations were similarly expressed in inactive disease at stage I-III. Furthermore, the levels of these cells after melanoma removal were apparently related to the disease activity since their persistent defect reflected high risk of recurrence and reduced the RFS. CONCLUSIONS This work highlighted the role of immune cell measurement for the management of melanoma activity and the identification of patients at potential risk of recurrence based on the mDC ratio.

Abstract
INTRODUCTION Lymphedema resulting from breast cancer treatment is a chronic condition that can significantly compromise quality of life. Several works have documented the efficacy of vascularized lymph node flap transfer (VLNT) for the treatment of advanced-stage lymphedema. Given that the axillary scar may contribute to the patient's existing lymphedema, the authors assumed that combining VLNT and scar release with fat graft could be an effective strategy of treatment. The purpose of this study is to compare the efficacy in the reduction of limb circumference and health-related quality of life between a combined strategy, namely, VLN transfer (VLNT) and axillary scar release with fat grafting, and only VLNT for patients affected by postmastectomy upper limb lymphedema. The idea. MATERIALS AND METHODS All patients with stage II and III breast cancer-related lymphedema operated between January 2012 and January 2016 were retrospectively identified, and only those treated by combined VLNT and scar release (Group A) or only VLNT (Group B) were included. The outcomes were assessed clinically by limb circumference measurement and radiologically by lymphoscintigraphy. Lymphedema-related quality of life was evaluated preoperatively and at 1 year follow-up through the LYMQOL questionnaire. RESULTS Thirty-nine patients met inclusion criteria (Group A = 18; Group B = 21). Mean follow-up was 29 months for Group A and 32 months for Group B. Flap survival rate was 100%, with no donor site morbidity in all patients. A statistically significant difference between the circumference reduction rates (RR) at above elbow level was observed at 3 and 6 months of follow-up comparing the two groups (p<0.00001), with higher values in Group A than in Group B. No significant difference was detected comparing RR values at above and below elbow at 12 and 24 months postoperatively. LYMQOL metrics showed significantly better scores (p<0.0001) in all domains at all follow-up appointments in Group A. CONCLUSIONS Patients with postmastectomy upper limb lymphedema can benefit from combined lymph node transfer and axillary scar release with fat graft, as this approach seems to fasten the onset of improvement and to have a positive impact on patients' quality of life.

Abstract
Nipple-areola complex (NAC) loss is one of the most devastating complications of mastopexy or breast reduction, and it requires revisional procedures with poor aesthetic outcome. In high-risk patients, a free nipple graft could be a choice, but it is associated with the same aesthetic concerns for both patients and surgeons. We report our experience with the septum-supero-medial-based mammaplasty to treat 22 patients with severe breast ptosis (nipple-to-sternal-notch distance > 40 cm). No NAC loss was observed. The study highlights surgical technical details and discusses anatomical considerations to justify the successful result.

Abstract
Nexobrid is a highly selective enzymatic debriding agent used in the acute management of burns to perform escharectomy. From October 2016 to April 2017, we treated 6 patients affected with lower limb chronic ulcers of different etiologies with Nexobrid in order to perform eschar removal by enzymatic debridement. For all patients, a dosage of Nexobrid, calculated as 2gr per 1% TBSA, was applied in a 2-3 mm thick uniform layer on the ulcer eschar and fibrin tissue and left for 4 hours, covered with an occlusive dressing. Patients were assessed in terms of ulcer cleansing 24 hours and 7 days post Nexobrid debridement, by wound bed score (WBS) and % of remaining necrotic tissue. A patient pain VAS was also recorded at 24 hours and 7 days post debridement. Adverse events at these time points were also noted. The results documented a complete removal of necrotic tissue in a time frame of 4 hours. At 24 hours, all lesions were completely debrided. At 7 days, there was a partial recurrence of necrotic tissue, as also documented by decreased WBS. All patients reported none to mild pain, and no adverse events were noted, except for mild erythema along the edges of the lesion on healthy skin in one case. This is a preliminary observation. Optimal dosage and application of Nexobrid in this indication needs to be validated by further controlled data.

Abstract
Volcanic gas emission measurements inform predictions of hazard and atmospheric impacts. For these measurements, Multi-Gas sensors provide low-cost in situ monitoring of gas composition but to date have lacked the ability to detect halogens. Here, two Multi-Gas instruments characterized passive outgassing emissions from Mt. Etna's (Italy) three summit craters, Voragine (VOR), North-east Crater (NEC) and Bocca Nuova (BN) on 2 October 2013. Signal processing (Sensor Response Model, SRM) approaches are used to analyse H2S/SO2 and HCl/SO2 ratios. A new ability to monitor volcanic HCl using miniature electrochemical sensors is here demonstrated. A "direct-exposure" Multi-Gas instrument contained SO2, H2S and HCl sensors, whose sensitivities, cross-sensitivities and response times were characterized by laboratory calibration. SRM analysis of the field data yields H2S/SO2 and HCl/SO2 molar ratios, finding H2S/SO2 = 0.02 (0.01-0.03), with distinct HCl/SO2 for the VOR, NEC and BN crater emissions of 0.41 (0.38-0.43), 0.58 (0.54-0.60) and 0.20 (0.17-0.33). A second Multi-Gas instrument provided CO2/SO2 and H2O/SO2 and enabled cross-comparison of SO2. The Multi-Gas-measured SO2-HCl-H2S-CO2-H2O compositions provide insights into volcanic outgassing. H2S/SO2 ratios indicate gas equilibration at slightly below magmatic temperatures, assuming that the magmatic redox state is preserved. Low SO2/HCl alongside low CO2/SO2 indicates a partially outgassed magma source. We highlight the potential for low-cost HCl sensing of H2S-poor HCl-rich volcanic emissions elsewhere. Further tests are needed for H2S-rich plumes and for long-term monitoring. Our study brings two new advances to volcano hazard monitoring: real-time in situ measurement of HCl and improved Multi-Gas SRM measurements of gas ratios.

Abstract
Eruptive activity at Turrialba Volcano (Costa Rica) has escalated significantly since 2014, causing airport and school closures in the capital city of San José. Whether or not new magma is involved in the current unrest seems probable but remains a matter of debate as ash deposits are dominated by hydrothermal material. Here we use high-frequency gas monitoring to track the behavior of the volcano between 2014 and 2015 and to decipher magmatic versus hydrothermal contributions to the eruptions. Pulses of deeply derived CO2-rich gas (CO2/Stotal > 4.5) precede explosive activity, providing a clear precursor to eruptive periods that occurs up to 2 weeks before eruptions, which are accompanied by shallowly derived sulfur-rich magmatic gas emissions. Degassing modeling suggests that the deep magmatic reservoir is ~8-10 km deep, whereas the shallow magmatic gas source is at ~3-5 km. Two cycles of degassing and eruption are observed, each attributed to pulses of magma ascending through the deep reservoir to shallow crustal levels. The magmatic degassing signals were overprinted by a fluid contribution from the shallow hydrothermal system, modifying the gas compositions, contributing volatiles to the emissions, and reflecting complex processes of scrubbing, displacement, and volatilization. H2S/SO2 varies over 2 orders of magnitude through the monitoring period and demonstrates that the first eruptive episode involved hydrothermal gases, whereas the second did not. Massive degassing (>3000 T/d SO2 and H2S/SO2 > 1) followed, suggesting boiling off of the hydrothermal system. The gas emissions show a remarkable shift to purely magmatic composition (H2S/SO2 < 0.05) during the second eruptive period, reflecting the depletion of the hydrothermal system or the establishment of high-temperature conduits bypassing remnant hydrothermal reservoirs, and the transition from phreatic to phreatomagmatic eruptive activity.

Abstract
Interval nodes (IN) are defined as lymph nodes that lie along the course of lymphatic collecting vessels between a primary tumor site and a draining node field. Sometimes INs contain metastases and a consensus on their surgical management is needed. Therefore, to optimize the surgical management of melanoma patients with metastatic lymphatic involvement, especially when the sentinel lymph node biopsy identifies an unusual drainage field, we identified patients treated at the Department of Plastic and Reconstruction Surgery of Bari between July 1994 and December 2012 identified with a primary-cutaneous melanoma who underwent lymphoscintigraphy and subsequent positive-IN the lymphadenectomy to evaluate the impact of this procedure on overall survival and disease-free-period. 51 patients presented INs, and lymphadenectomy (LA) of the subsequent lymphatic field was performed in 13 subjects with positive-IN. In 4 cases additional lymphatic metastases were detected in the usual basin beyond the IN+. Recurrence-free period and survival rate at 5 years were higher in patients with positive-IN who underwent LA than in subjects who underwent LA due to positive lymph nodes in the usual field. Immediate lymphadenectomy of the subsequent lymphatic field in patients with positive-INs may afford patients earlier stage treatment of their disease and improved prognosis.

Abstract
Furnas volcano, in São Miguel island (Azores), being the surface expression of rising hydrothermal steam, is the site of intense carbon dioxide (CO2) release by diffuse degassing and fumaroles. While the diffusive CO2 output has long (since the early 1990s) been characterized by soil CO2 surveys, no information is presently available on the fumarolic CO2 output. Here, we performed (in August 2014) a study in which soil CO2 degassing survey was combined for the first time with the measurement of the fumarolic CO2 flux. The results were achieved by using a GasFinder 2.0 tunable diode laser. Our measurements were performed in two degassing sites at Furnas volcano (Furnas Lake and Furnas Village), with the aim of quantifying the total (fumarolic + soil diffuse) CO2 output. We show that, within the main degassing (fumarolic) areas, the soil CO2 flux contribution (9.2 t day-1) represents a minor (~15 %) fraction of the total CO2 output (59 t day-1), which is dominated by the fumaroles (~50 t day-1). The same fumaroles contribute to ~0.25 t day-1 of H2S, based on a fumarole CO2/H2S ratio of 150 to 353 (measured with a portable Multi-GAS). However, we also find that the soil CO2 contribution from a more distal wider degassing structure dominates the total Furnas volcano CO2 budget, which we evaluate (summing up the CO2 flux contributions for degassing soils, fumarolic emissions and springs) at ~1030 t day-1.

Abstract
BACKGROUND Although the number of excised LNs has been associated with patient prognosis in many solid tumors, this association has not been widely investigated in cutaneous melanoma. This study aims to evaluate the association between the number of excised regional lymph nodes (LNs) and melanoma-specific survival. PATIENT AND METHODS Clinico-pathological data from 2507 patients with LN metastasis treated at nine Italian centers were retrospectively collected. RESULTS The number of excised LNs correlated with younger age (P < 0.001), male sex (P < 0.001), neck LN field (P < 0.001), LN micrometastasis (P < 0.001) and number of positive LNs (P < 0.001). The number of excised LNs was an independent prognostic factor (HR = 0.85; P = 0.002) after adjustment for other staging features. Upon subgroup analysis, the number of excised LNs had a significant prognostic value in patients bearing 1.01-2.00 mm (HR = 0.79; P = 0.032) and 2.01-4.00 mm (HR = 0.71; P < 0.001) thick melanomas, primary tumors showing ulceration (HR = 0.86; P = 0.033) and Clark level V of invasion (HR = 0.86; P = 0.010), LN micrometastasis (HR = 0.83; P = 0.014) and two to three positive LNs (HR = 0.71; P = 0.001). Finally, this study investigated the influence of the number of excised LNs on patient staging: only when ≥11 nodes were excised the AJCC N stage could stratify prognosis (P < 0.001). Considering the number of excised LNs for each lymphatic field, at least 14, 11, 10 and 12 LNs were needed to stage patients according to the AJCC N stage after a lymphadenectomy of the neck, axilla, inguinal and ilioinguinal LN fields, respectively. CONCLUSIONS The number of excised LNs can be considered for risk stratification of patients with regional LN metastasis from cutaneous melanoma. We demonstrated that a minimum number of LNs is required for the correct staging of patients. Further research is needed to evaluate the effectiveness of the minimum number of LNs to be dissected.

Abstract
The aim of our studies was to establish a standard method of assessment that allows an early identification of frailty in the elderly, i.e., to predict who are at risk of developing disabilities, in order to be able to intervene with preventive global and individualized measures. A new multidimensional scale called Marigliano-Cacciafesta polypathological scale (MCPS) was used on 180 elderly people, together with the Barthel index (BI), the global evaluation functional index (GEFI), the geriatric depression scale (GDS), the mini mental state examination (MMSE), the mini nutritional assessment (MNA), and the Tinetti test. A strongly significant statistical correlation was found between the MCPS and the nutritional state, mood level, motor functionality, level of disability and global functionality. As the fragile patients are at a risk to develop disabilities, we think that our scale can be a significant contribution to the multidimensional geriatric assessment (MGA), aimed at identifying and quantifying the parameter of fragility of each patient, an information which should be known, if we intend to introduce preventive measures.

Abstract
Stem cells are presumed to survive various stresses, since they are recruited to areas of tissue damage and regeneration, where inflammatory cytokines and cytotoxic cells may result in severe cell injury. We explored the ability of mesoangioblasts to respond to different cell stresses such as heat, heavy metals and osmotic stress, by analyzing heat shock protein (HSP)70 synthesis as a stress indicator. We found that the A6 mesoangioblast stem cells constitutively synthesize HSP70 in a heat shock transcription factor (HSF)-independent way. However, A6 respond to heat shock and cadmium treatment by synthesizing HSP70 over the constitutive expression and this synthesis is HSF1 dependent. The exposure of A6 to copper or to a hypertonic medium does neither induce HSP70 synthesis nor activation of HSF1, while a constitutive binding of constitutive heat shock element binding factor was found. Together, these data suggest that mesoangioblasts constitutively express HSP70 as an 'a priori' activation mechanism, while they maintain the ability to respond to stress stimuli.

Abstract
Different factors influence animal sperm ability to fertilize. Some of them are reviewed here, sperm motility, block to polyspermy, chemioattraction, sperm competition for fertilization. Old and new data are reported, as for example the new notions on sperm motility derived from site directed mutagenesis in rodents, the new notions on the odour receptors in mammalian sperm attraction and new notions on sperm competition, which is variable in different species.

Abstract
Between 1996 and 2003 a total of 19 humeral head osteotomies were performed to treat post-traumatic malunion of the proximal humerus. Mean age was 46 years, ranging from 17 to 71 years. The period of time between traumas and surgeries ranged from 6 to 22 months. Osteotomy procedure was as follows: one after two-part fracture of the greater tuberosity, three after two-part fracture of the surgical neck, five after three-part fracture of the greater tuberosity, eight after four-part fracture, two after complex head splitting fracture, one after two-part fracture with anterior dislocation. Three different types of osteotomies were performed: osteotomy of the humeral neck for varus deformity, isolated osteotomy of the greater tuberosity, and a new osteotomy technique (two-plane and three-plane osteotomy) for three- and four-fragment fracture sequelae. At the time of follow-up evaluation, all 19 patients were questioned regarding pain and function. Excellent results in 14 patients and satisfactory results in 5 were obtained. None of the patients required revision surgery. Findings were recorded using the Constant rating scale. All patients had had significant pain relief after shoulder osteotomy. Range of motion was increased in all patients treated by osteotomy. The success of osteotomy in these cases was based on: patient selection, extensive preoperative evaluation, surgical technique and postoperative rehabilitation.

Abstract
Purpose of this study is to analyze the results of a consecutive series of 139 patients affected with anterior-inferior shoulder instability and treated by arthroscopic capsuloplasty using the Thal method with absorbable and non-absorbable Mitek knotless anchors. Much attention was paid to the preoperative and intraoperative selection of patients, excluding from the arthroscopic procedure those with bony Bankart lesions measuring more than 25%, with an inverted-pear glenoid, with engaged Hill-Sachs lesions and patients with HAGL lesions. Pre- and postoperative clinical evaluation was carried out using the Rowe scale. Scores rose from 45-55 to 96 postoperatively. Intra-articular mobilization of the anchors did not occur and peri-metallic lysis was not manifested. Areas of bone resorption were observed in 7 cases (7/38, 18.4%) with the presence of peri-insertional geodes with biological anchors, but this had no effect on the clinical results.

Abstract
AIM Superior vena cava syndrome is a dramatic event that can be cured in specialized centers. METHODS Between 1989 and 1995 6 patients with superior vena cava syndrome underwent surgical treatment for thoracic tumors. In all cases the vena was restricted by a neoplastic sleeve. A median sternotomy was performed in all cases. Two patients received an associated right anterolateral thoracotomy to obtain good surgical exposure for tumor resection and grafting. A 12 mm diameter polytetrafluoroethylene graft was inserted in all cases. The tumor resection was radical in 4 cases (2 thymic carcinomas, 2 malignant germ cell tumors) and palliative in 2 (1 non-small cell lung cancer and 1 mediastinal fibrosis). RESULTS We had no in-hospital mortality. All patients had immediate relief of obstruction after by-pass. Three patients were alive without disease at the end of follow-up (40-96 mo), one patient died of postoperative complications after 4 mo, 2 patients died of disease after 4 and 12 mo. CONCLUSION PTFE by-pass graft for treatment of the obstructed SVC relieves SVC syndrome and has good medium term patency.

Abstract
Results of this multicentric study have shown that by giving Master Amino acid Pattern (MAP) as a sole and total substitute of dietary proteins to 500 overweight participants undergoing the American Nutrition Clinics/Overweight Management Program (ANC/OMP), the participants' body nitrogen balance could be maintained in equilibrium with essentially no calories (MAP 1 g=0.04 kcal), thereby preserving the body's structural and functional proteins, eliminating excessive water retention from the interstitial compartment, and preventing the sudden weight increase after study conclusion commonly known as the yo-yo effect. Study results have shown that the use of MAP, in conjunction with the ANC/OMP regimen, has proven to be safe and effective by preventing those adverse effects associated with a negative nitrogen balance, such as oversized or flabby tissue, stretch marks, the sagging of breast tissue, increased hair loss, faded hair color, and fragile or brittle nails. Also prevented were those anomalies commonly associated with weight-loss diets, such as hunger, weakness, headache caused by ketosis, constipation, and decreased libido. The use of MAP in conjunction with the ANC/OMP also allowed for mean weight loss of 2.5 kg (5.5 lb) per week, achieved through reduction of excessive fat tissue and elimination of excessive water retention from the interstitial compartment.

Abstract
OBJECTIVE This retrospective study evaluates the survival impact of the residual margin disease after bronchial resection for cancer and suggests tactics in cases of microresidual disease. METHODS Between March 1988 and 1998, 4530 consecutive patients underwent surgery for non-small cell lung cancer at our institution. Only incomplete resections after microscopic evaluation (R1) were included in the study. Residual tumour cells were found on the bronchial resection margins of 39 lobectomies, 12 pneumonectomies, 4 segmental resections and one bilobectomy. Histological findings were: squamous cell carcinoma in 38 cases, adenocarcinoma in 15 and large cell carcinoma in three. In all 56 cases, invasive mucosal carcinoma was found exclusively on the bronchial resection margin. Nineteen tumours were stage I; 12, stage II; 17, stage IIIa; 5, stage IIIb; and three, stage IV. Nineteen patients (59.3%) with early stage tumours (I and II) received adjuvant radiation therapy and only three chemotherapy. RESULTS The prognosis in these cases was disease-stage related (21 and 38.4% of deaths due to the disease). Forty-one percent of the stage IIIa patients received radiation therapy and 17.6% chemotherapy: 70.6% died of tumour relapse. Forty percent of the stage IIIb patients received radiation therapy and 20% chemotherapy: 60% died of disease progression. All of the stage IV patients died within 3 months from surgical resection. At the end of the study, 21 patients were alive after an interval of 22-142 months (18 in stage I or II). The 10-year actuarial survival rate was 44%. The percentage survival for stage IIIa was 16.8, after 10 years, and fell to 45 months for stage IIIb. CONCLUSIONS The prognosis of our stage I or II patients with microresidual tumour on the bronchial resection margin (R1) was similar to that of the patients in the same disease stage, whose resection was microscopically radical (R0) and the same was true of the patients in stage III. In patients with residual tumour cells on the bronchial stump we did not observe worsened long-term survivals.

Abstract
Careful quantitative analyses by spot hybridization to homologous probes demonstrate that no rDNA amplification occurs during Paracentrotus lividus oogenesis. The same approach was used to measure the copy number of the genes involved in ribosome biogenesis. Surprisingly, differently from the organisms in which the lack of rDNA amplification phenomena was observed, a very low number of constitutive rDNA repeats was found in this organism.

Abstract
Pulsus alternans was observed in a child with left ventricular dysfunction secondary to systemic hypertension. The Echo-Doppler of supravalvular aorta and a simultaneous electrocardiographic trace (ECG) clearly demonstrated the mechanism of an apparent abrupt halving of pulse frequency compared with the ECG, similar to an electromechanical dissociation 2:1. Besides the extreme pulsus alternans, a P wave and a PP cycle length change were also observed. Both mechanical and electrical alternans disappeared with afterload reduction by nitroprusside treatment.

Abstract
PURPOSE To propose a graded classification of lesions of the fibrocartilaginous glenoid labrum in traumatic dislocations of the shoulder, based on arthro-MRI in sagittal-oblique views. MATERIALS AND METHODS Seventy-one patients with histories of chronic post-traumatic shoulder instability were studied from May 2000 to May 2001. MR images were obtained using superconducting magnets operating at 1 and 1.5 Tesla, with a dedicated shoulder coil. The study was carried out in combination with arthrography, with axial sections oriented perpendicularly to the longitudinal axis of the glena, oblique coronal sections parallel to the course of the supraspinous muscle tendon and oblique sagittal sections with axis parallel to the longitudinal axis of the glena. RESULTS In one case an anatomical variant was found (Buford complex). In 18 patients a simple fissuration of the fibrocartilaginous glenoid labrum was found, whereas 28 patients displayed more extensive lesions affecting the middle-inferior portions of the labrum. In 15 patients the lesion extended to the middle-superior third of the glena, involving the middle glenohumeral ligament. In 9 cases, in addition to a complete lesion of the labrum, with typical "bucket-handle" appearance, a lesion of the superior and middle glenohumeral ligaments was also observed. DISCUSSION AND CONCLUSIONS In traumatic shoulder dislocations it is essential to provide the surgeon with precise information regarding the location, extension and degree of damage to the capsule, ligaments and especially the labrum of the glenohumeral joint. On the basis of the results obtained in the sagittal-oblique sections we propose an MR-arthrography classification dividing lesions of the fibrocartilaginous labrum into 4 grades.

Abstract
This review discusses examples of conserved cellular and molecular mechansims in development, including the pathway of signal transduction between the photoreceptors R8 and R7 in Drosophila, which is compared to vulval induction in Caenorhabditis elegans. The Wg pathway in Drosophila is compared, first, to the Wnt pathway in dorsal mesoderm specification in Xenopus: second, to the same pathway in sea urchins; third, to the equivalent in the mom cascade of C. elegans; and finally, to parts of the equivalent pathway in Dictyostelium discoideum. The conserved expression of some hox genes in vertebrate limb buds and in the heads or tails of several invertebrate and vertebrate embryos is also illustrated. Two further examples show the contrast between BMP4 and the proteins Noggin, Chordin, Follistatin and Gremlin. Another example concerns the binding of proteins to the 3'UTRs of several messages which inhibits their translation in Drosophila and C. elegans. The final example illustrates the selective transfer of transcription factors to nuclei in Drosophila and C. elegans.

Abstract
BACKGROUND The aim of this study is to evaluate the impact of thymectomy in patients with thymic neoplasms and to identify clinical and histopathological factors associated with improved long-term outcome of surgery. METHODS We treated 74 patients between February 1987 and July 1993. There were 29 total and 36 simple thymectomies. These last cases, all non-myasthenic, had benign thymomas (n=30) but 6 had thymic carcinomas. Nine tumors were no-resected (5 thymomas and 4 thymic carcinomas). Minimum follow-up by Department of Thoracic Surgery Istituto Nazionale Tumori was 60 months after thymectomy. We divided the specimens according to Marino and Muller-Hermelink's classification: 54 thymomas, 18 thymic carcinomas and 2 no-diagnosis specify thymomas. There were 53 stage I, 1 stage II, 13 stage III, 5 stage IVa and 2 stage IVb according to Masaoka. RESULTS Forty-six patients with treated thymoma were alive without disease at the end of follow-up, the remaining 8 died from recurrence in 6, a new tumor in 1 and a heart attack in the last. Of 18 thymic carcinomas 9 were alive at the end of follow-up (1 with recurrence), only 4 dead from recurrence. The actuarial survival of patients with thymomas was 88.5% at 5 years, (73.6% in cortical type, 85.7% in medullary type, 93.9% in mixed type, 100% in predominantly cortical type). Myasthenia gravis didn't influence the survival: 87.3 (no MG) vs 90%. Advanced stage thymomas significantly increased the risk of death from early stage I: 32.4 vs 100% at 5 years. In thymic carcinoma patients with well-differentiated thymic carcinoma (WDTC) died less than others: the actuarial probability of survival at 5 years was 90 vs 68%. CONCLUSIONS Thymectomy was the best treatment to long term outcome. In our experience, survival was related to histotype and to local extension of tumor.

Abstract
In the present study, double immunofluorescence and immunoblot analysis have been used to show that centrosomes, isolated from Paracentrotus lividus sea urchin embryos at the first mitotic metaphase, contain the constitutive chaperone, heat-shock protein (HSP) 70. More specifically, we demonstrate that centrosomes contain only the HSP70-d isoform, which is one of the four isoforms identified in P. lividus. We also provide evidence that p34(cell division control kinase-2) and t complex polypeptide-1 (TCP-1) alpha, a subunit of the TCP-1 complex, are localized on the centrosomes. Furthermore, inhibition of TCP-1 in vivo, via microinjecting an anti-(TCP-1 alpha) antibody into P. lividus eggs before fertilization, either impaired mitosis or induced severe malformations in more than 50% of embryos. In addition, we have isolated the whole mitotic apparatus and shown that HSP70 localizes on the fibres of spindles and asters, and binds them in an ATP-dependent manner. These observations suggest that HSP70 has a chaperone role in assisting the TCP-1 complex in tubulin folding, when localized on centrosomes, and during the assembling and disassembling of the mitotic apparatus, when localized on the fibres of spindles and asters.

Abstract
The influence of actin and tubulin cytoskeletons on the shape, division and on intracellular motility of mitochondria was studied in eggs and embryos of the sea urchin Paracentrotus lividus. Depolymerization of actin filaments and microtubules was induced by specific inhibitors as cytochalasin D (CytD) and colcemid respectively. The quantitative analysis of the mitochondrial population shows that: 1) the chondriome of an egg consists of numerous (about 15,000) discrete mitochondrial clusters uniformly distributed throughout the cytoplasm, each cluster containing 10 to 20 mitochondria of spherical or rod-like shape; 2) fertilization induces cluster break-down and mitochondrial division within 15 min after insemination; at 100 min after fertilization mitochondria become evenly distributed throughout the cytoplasm and the population of mitochondria doubles; 3) in embryos obtained from eggs inseminated after treatment with CytD clusters break-down and mitochondriokinesis are blocked; 4) when added 15 min after insemination, CytD uncouples coordinated invagination of outer and inner membranes in dividing mitochondria thus bringing about abnormal mitochondriokinesis; 5) the treatment of the eggs with colcemid does not affect the normal embryonic mitochondriokinesis.

Abstract
From January 1980 to December 1999, 88 patients underwent surgical resection for tumours involving the sternum. Thirty were males, aged 16 to 76 years, and 58 females, aged 23 to 78 years (mean ages: 48 and 53 years, respectively). There were 30 primary malignant tumours, 28 local recurrences or distant metastases from breast cancer, 16 other tumours, and 14 radionecroses. Total sternectomy was performed in 8 cases, subtotal (> 50%) in 32, and partial (< 50%) in 48. Concurrent en-bloc resection of the anterior ribs was performed in 61 patients, and of the clavicle in 13. Resection was extended to the lung in 22 patients, to the pericardium in 17, to both in 2, to the diaphragm and pericardium in 4. Bone and soft tissue defects were repaired with prosthetic material associated with a muscular or myocutaneous flap in 55 patients, with prosthetic material alone in 13 cases, with a muscular or myocutaneous flap in 5 cases, and with other techniques in the remaining patients. The resection was considered to be macroscopically radical in 78 patients and palliative in 10 cases. There was one perioperative mortality and significant morbidity was limited to 13 cases. Among the patients treated with a radical intent, 48 were alive and disease-free at the end of follow-up. The 10-year survival rate was 85% in primary tumours. For breast cancer relapses, 10-year survival was the same as 5-year survival (41.8%). In our experience, an en-bloc sternal resection for a primary or secondary tumour, followed by plastic repair using prosthetic material and/or a myocutaneous flap, is a safe, effective treatment. This intervention permits the execution of extensive radical resections for sternal neoplasms, as well as enabling the patient to obtain a better quality of life. Long-term survival after radical sternectomy also depends on the histological type of the tumour.

Abstract
The dynamics of structural changes of the chondriome in the early development of the sea urchin Paracentrotus lividus was studied. Mature eggs and embryos at various stages of cleavage were used for quantitative and ultrastructural analysis based on computerized 3D reconstruction from serial ultrathin sections. The following structural transformations of the chondriome were shown to occur in the course of embryogenesis: (i) 15 min after fertilization, mitochondrial clusters disintegrate, and mitochondrial division is induced. At the stage of two blastomeres the population of mitochondria increases twofold; (ii) the mitochondria divide by means of the contraction of both outer and inner membranes. The forming furrow divides the "parental" mitochondrion into two equal "daughter" parts; (iii) at the four-cell stage the division ceases, and mitochondria start to grow, so that the mitochondrial length increases; (iv) cell differentiation further stimulates elongation of rod-shaped mitochondria, and the ratio of rod-shaped to spherical mitochondria changes; (v) in an unfertilised egg, the mitochondria are in a condensed form; after fertilisation all the mitochondria acquire a conventional form. Modern concepts of chondriome proliferation in eukaryotic cells are discussed.

Abstract
The dynamics of structural and functional organization of the nucleolus in the oocytes of P. lividus is described. At the late stages of oogenesis the nucleolus is composed of two main components, namely the peripheral zone (PZ) and the central zone (CZ) which are spatially separated. This two-component structure of the nucleolus is formed, at early stages of oogenesis, by stepwise segregation of the fibro-granular component and by its migration to the nucleolar periphery. Absence of morphologically distinct fibrillar centers and dense fibrillar component in nucleoli of both somatic cells and oocytes makes it possible to classify the nucleoli of P. lividus as 'noncanonical' type. Based on detailed morphological and cytochemical analysis the following molecular interpretation of nucleolar ultrastructure in oocytes of P. lividus is proposed: 1) the PZ, containing RNP-positive granules 15 nm in size, but lacking Ag-NOR proteins and BrU incorporation, can be considered a structural equivalent of the granular component of 'typical' nucleoli; 2) the CZ, which is the site of incorporation of RNA precursors, contains intranuclear DNA, RNP-fibers and accumulates Ag-NOR proteins, corresponds to both FC and DFC of 'typical' nucleoli; 3) nucleolar growth during oogenesis, leading to the 1000-fold increase of nucleolar volume, seems to be correlated with the stockpiling of nonfunctioning mature preribosomal particles which will be utilized during embryogenesis.
