Head and neck squamous cell carcinoma of the (HNSCC) represents approximately 5% of malignant tumours in Italy. HNSCC are commonly treated with surgery or radiotherapy, or a combination of such therapies. The objectives of treatment are maximum cure rate balanced with organ preservation, restoration of form and function, reduction of morbidities and improvement or maintenance of the patient's quality of life. Immediate reconstructive surgery: local, regional or free flaps are now widely advised in the treatment of these patients. Microsurgical transfer requires expertise, is time and resource consuming, and as a whole requires substantial costs. These considerations introduce some concerns about the wide or indiscriminate use of free flap reconstructive surgery. When considering cost-benefit outcomes of such treatment, the main objective is undoubtedly, survival. This data is underreported in the current literature, whereas functional outcomes of free flaps have been largely diffused and accepted. This study collects data from 1178 patients treated with free flap reconstructive surgery following ablation of HNSCC in a group of Italian tertiary hospitals, all members of the HeadNeck Group affiliated with the Italian Society of Microsurgery. According to many authors, free flap surgery for HNSCC seems to be a beneficial option for treatment even in terms of survival.I tumori spinocellulari del distretto Cervico Facciale rappresentano circa il 5% dei tumori maligni in Italia. Essi sono comunemente trattati con chirurgia o radioterapia, o entrambi le terapie. La ricostruzione rappresenta un momento fondamentale della terapia nel rispetto della qualità di vita di questi pazienti. La microchirurgia ricostruttiva rappresenta la tecnica che offre i migliori risultati funzionali ma è oggetto di discussione in un rapporto costo-benefici. In questo lavoro sono raccolti ed analizzati i dati di 1178 pazienti provenienti dai membri del gruppo testa e collo, affiliato alla società Italiana di Microchirurgia, e i cui dati sono rapportati primariamente alla sopravvivenza.

Usually, harvesting free flap in the limbs creates an inevitable sequence of aesthetic damage not only in the donor site but also in the area of the graft used to repair the free flap donor site. Aim of the study was to standardize a simple method, defined Autonomous Reparative Unit, that allows closing of the donor site defects with a skin graft from the adjacent cutaneous area, avoiding further aesthetic damage in a third area. We define the "Autonomous Reparative Unit" as the rectangular shaped skin area of the flap and the dermoepidermic skin graft designed as an isoscele triangle with the base adjacent to the smaller side of the flap defect. From 2003 to 2008, at the Fondazione IRCCS Istituto Nationale Tumori of Milan, 143 free radial forearm flaps and 42 free osteofasciocutaneous fibula flaps have been performed for head and neck cancer. The autonomous reparative unit has been applicable in 177 cases (92.1%). The autonomous reparative unit method allows a "standard"primary reconstructive unit to be created which can be used in a single or in multiple ways thus avoiding an additional surgical scar and a subsequent additional aesthetic impairment.

We have applied the digital pulse shape acquisition to readout the signals coming from the position-sensitive start detector of the MAGNEX spectrometer in order to obtain the position coordinates using digital signal processing.

At the Cranio-Maxillo-Facial Surgery Unit of the Istituto Nazionale per lo Studio e la Cura dei Tumori in Milan, Italy between 1987 and 1999 200 anterior cranio-facial resections were performed on malignant ethmoid tumors involving the anterior cranial base and extending to the nasal fossae and, at times to the orbit and maxillary and sphenoid sinuses. In the second portion of this case study the authors simplified their surgical technique. The frontal craniotomy was made rectangular and low, performed with an oscillating saw and scalpel, without drilling holes. The osteotomy of the cranial base was modulated according to tumor extension. Typically a paralateronasal facial incision was performed without opening the upper lip. Whenever the maxillary sinus and/or orbit were involved, the skin incision and osteotomy was consequently modified. Repair of the cranial base was performed with a pedicled pericranial flap. In this case study there were 6 post-operative deaths in the first 30 patients and only 2 in the remaining 170. The male/female ratio was 145/55, mean age 55 years (12-80) and average follow-up 38 months (2-117). There were 120 primary tumors while the remaining 80 patients presented recurrences from prior treatments. There were 96 adenocarcinomas, 42 spinocellular carcinomas, 21 esthesioneuroblastoma 15 adenoid-cystic carcinomas, 9 melanomas and 17 rare tumors. Our classification identified the following stages: 69 T2, 54 T3 and 77 T4 while the UICC-AJCC staging system indicated: 25 T1, 16 T2, 68 T3 and 91 T4. The NED survival according to tumor stage (INT classification) was: T262.3%, T3 44.4% and T4 29.9%. The NED survival for patients who had not previously undergone treatment was: T2 71.7%, T3 58.8% and T4 42.5%. On the other hand the NED survival for the cases of recurrence was: T2 43.5%, T3 20% and T4 16.2%. These results lead to the conclusion that the surgical technique currently used is valid and that the anterior cranio-facial resection should always be performed in patients with ethmoid tumors coming into contact with, or eroding, the cribriform plate. For all staging classes, the prognosis for those patients undergoing surgery for recurrence from prior, inadequate treatment was significantly worse than that for the primary tumors.

The Authors examine serum levels of HPRL in basal conditions and after TRH and sulpiride test in 15 patients with endometrial lesions (hyperplasia) and in 15 patients with endometrial adenocarcinoma included in a age range between 44 and 62 years, in which 7 patients present obesity, 10 patients present hypertension and 2 patients are hyperglycemic. The same examination is carried out in a control group of 30 healthy patients. Then the 15 patients with adenocarcinoma and 3 patients with adenomatosa hyperplasia are subjected to surgery and they estimate HPRL levels in endometrium. The results prove that there is no correlation between HPRL plasma levels and endometrium lesions and between endometrium HPRL. The Authors conclude that HPRL does not play a significant role in the pathogenesis of endometrial lesions; use of HPRL plasma levels as a marker of endometrial lesions is not possible.

Background Increased incidence of central precocious puberty (CPP) after coronavirus infectious disease-19 lockdown has been reported. Our study aims in investigating changes in CPP rates and in sleep patterns in CPP and healthy controls. Methods CPP were retrospectively evaluated from April 2020 to April 2021. Parents of girls diagnosed with CPP during lockdown and of matched healthy controls filled out a questionnaire about sleep disturbances (SDSC questionnaire) and sleep schedules. Results Thirty-five CPP and 37 controls completed the survey. Incidence of new CPP cases significantly increased in 2020–2021 compared to 2017–2020 (5:100 vs 2:100, p = 0.02). Sleep disturbance rates did not differ between CPP and healthy controls before lockdown. During lockdown, CPP reported higher rates of sleep disturbs for total score (p = 0.005), excessive somnolence (p = 0.049), sleep breathing disorders (p = 0.049), and sleep–wake transition disorders (p = 0.005). Moreover, CPP group more frequently shifted toward later bedtime (p = 0.03) during lockdown compared to controls. Hours of sleep and smartphone exposure around bedtime did not differ between groups. Conclusions Our study confirms the observation of increased incidence of CPP after lockdown measures. Additionally, CPP showed higher rates of sleep disturbances and later bedtime compared to controls. The causality link between sleep disturbances and CPP should be further investigated to gain knowledge in this association.

We aimed to evaluate the prognostic value of renal length (RL) > 2 standard deviation scores (SDS) measured by renal ultrasound (RUS), across infancy, childhood and adolescence, in identifying which patients with congenital solitary functioning kidney (CSFK) are at lower risk of developing kidney injury (KI). We also estimated the cost saving of integrating the current follow-up protocols with an early RUS algorithm (ERUSA). Fifty-six CSFK adult patients who were 1–3 months old at first observation of undergoing RUS were enrolled. KI was defined by hypertension and/or proteinuria and/or declined renal function. ERUSA was assessed by early (at 1–3 months of life) RUS and was retrospectively tested in our patients. ERUSA establishes that patients with RL > 2SDS at early RUS do not undergo further follow-ups. The others undergo another RUS at 1 year of age along with follow-ups according with current protocols, with the exception of RUS which could be no longer performed. Direct and indirect costs were calculated for each analysed protocol and the cost saving of applying ERUSA was calculated. None of the patients with early RL > 2SDS presented KI in adulthood. A RL > 2SDS was predictive of absence of KI only at 1–3 months (OR = infinity) and 1 year of age (OR = 0.13; 95%CI: 0.03–0.66; p = 0.01). ERUSA provided a total cost-sparing ranging from 38.6% to 55.3% among the analysed follow-up protocols. With ERUSA, no patients developing KI in adulthood were missed. In conclusion, only a RL > 2SDS at 1–3 months and 1 year of age predicted good prognosis in young adulthood. ERUSA can guide a cost-sparing follow-up strategy in CSFK patients while maintaining important long-term information.

Renal diseases in childhood form a spectrum of different conditions with potential long-term consequences. Given that, a great effort has been made by researchers to identify candidate biomarkers that are able to influence diagnosis and prognosis, in particular by using omics techniques (e.g., metabolomics, lipidomics, genomics, and transcriptomics). Over the past decades, metabolomics has added a promising number of ‘new’ biomarkers to the ‘old’ group through better physiopathological knowledge, paving the way for insightful perspectives on the management of different renal diseases. We aimed to summarize the most recent omics evidence in the main renal pediatric diseases (including acute renal injury, kidney transplantation, chronic kidney disease, renal dysplasia, vesicoureteral reflux, and lithiasis) in this narrative review.

Due its close relationship with obesity, nonalcoholic fatty liver disease (NAFLD) has become a major worldwide health issue even in childhood. The most accepted pathophysiological hypothesis is represented by the "multiple hits" theory, in which both hepatic intracellular lipid accumulation and insulin resistance mainly contribute to liver injury through several factors. Among these, lipotoxicity has gained particular attention. In this view, the pathogenic role of different lipid classes in NAFLD (e.g., sphingolipids, fatty acids, ceramides, etc.) has been highlighted in recent lipidomics studies. Although there is some contrast between plasma and liver findings, lipidomic profile in the NAFLD context provides novel insights by expanding knowledge in the intricate field of NAFLD pathophysiology as well as by suggesting innovative therapeutic approaches in order to improve both NAFLD prevention and treatment strategies. Selective changes of distinct lipid species might be an attractive therapeutic target for treating NAFLD. Herein the most recent evidence in this attractive field has been summarized to provide a comprehensive overview of the lipidomic scenario in paediatric NAFLD.

Il contributo affronta in chiave critica le recenti modfiche normative seguite alla l. n. 47 del 2015 in tema di misure cautelari. L'analisi riguarda in particolare le innovazioni sulla motvazione cautelare e le ripercussioni sulla morfologie del controllo a opera dei giudici del riesame. Si verificano analiticamente le modifiche alla tempistica di decisione dell'appello e alla cassazione cautelari e alla partecipazione dell' indagato in una prospettiva attenta ai valori convenzionali e costituzionali.
