Postoperative care in finger replantation. Our case-load and review of the literature
OBJECTIVE:
Technical success of a finger replantation depends on several factors such as surgical procedure, type of injury, number of segments amputated, amputation level and individual patient factors. Among early complications that can occur in this type of surgery the onset of venous or arterial thrombosis is the most dreaded. Local irrigating solutions, oral and intravenous anticoagulants, thrombolytic agents, plasma expanders, vasodilating, and antiaggregant drugs are routinely used in patients undergoing microvascular procedures, but currently there is only a non-standardized practice based on anecdotal personal experience.
MATERIALS AND METHODS:
The aim of our study is to review selected literature relating to perioperative therapy in microsurgical digital replantation. We also report our case-load of 16 patients with finger avulsion describing our particular protocol for postoperative anticoagulation and restoration of fluid and electrolyte balance.
RESULTS:
Following our daily pharmacological protocol, the postoperative course of the replanted fingers was uneventful. The survival rate for finger replantations performed was 100% (n = 16) with no need for surgical revisions.
CONCLUSIONS:
The association Dextran-40/Heparin/fluids in the proposed standardized pro-weight pharmacological protocol is an optimal postoperative prophylactic/therapeutic plan to reduce the incidence of endovascular thrombosis after replantation, so ensuring high rate of success in microvascular surgery

Coverage of exposed hardware after lower leg fractures with free flaps or pedicled flaps
Abstract. – OBJECTIVE: The placement of osteosynthetic materials in the leg may be complicated by hardware exposure. Successful soft tissue reconstruction often provides a critical means for limb salvage in patients with hardware exposure in the leg. Free flaps are currently considered the standard surgical procedure for soft tissue coverage of the wounds with internal hardware exposure. However, to date, no conclusive literature shows the superiority of a specific type of flap. MATERIALS AND METHODS: The current review compares data from the literature concerning outcomes and complications of free and pedicled flaps for exposed osteosynthetic material preservation in the leg. RESULTS: A total of 81 cases from twelve different articles presenting internal hardware exposure of the leg were analyzed in our study. Thirty-two patients underwent immediate reconstructive surgery with pedicled flaps, while forty-nine patients underwent free flap reconstruction. The overall survival rate for pedicled flaps was 96.77%, while for free flaps it was 97.77%. The overall implant preservation rate was 78.12% for pedicled flaps and 53.33% for free flaps. With reference to postoperative complications, the overall complication rate was 46.87% for pedicled flaps and 10.20% for free flaps. CONCLUSIONS: No significant difference was found in terms of overall flap survival. However, a significant difference was found regarding successful implant preservation (78.12% in the pedicled flap group vs. 53.33% in the free flap group). In particular, the first observation appears to be in contrast with the current trend of considering the free flaps the first choice procedure for soft tissue coverage of the wounds with internal hardware exposure. Nevertheless, a higher occurrence of postoperative complications was observed in the pedicled flap group (46.87% vs. 10.20%). The choice of the most appropriate reconstructive procedure should take into account several issues including the size of the wounds with internal hardware exposure, the possibility of soft tissue coverage with pedicled flaps, the availability of recipient vessels, general conditions of the patients (such as age, diabetes, smoking history), patients’ preference and presence of a microsurgical team. However, according to the results of this review, we believe that pedicled flap reconstruction should be reconsidered as a valid alternative procedure for skin tissue loss with hardware exposure whenever it is possible

Serum levels of total IgE and soluble CD23 in bronchial asthma
The aim of the present study was to compare, during the pollen season, serum levels of total IgE and soluble CD23 (sCD23) from patients with allergic bronchial asthma, with those from healthy subjects. Significantly higher levels of total IgE and sCD23 were found in patients with asthma compared to the control group. Both in normal controls and in asthmatic patients, a significant correlation was shown between the levels of these two molecules. In asthmatic patients, significant correlations were found for both total IgE and sCD23, with lung function measured as bronchial responsiveness to inhaled methacholine. These results suggest that in asthmatic patients, in addition to the study of total serum IgE levels, the assessment of sCD23 serum levels may be helpful in the evaluation of disease activity
Sicurezza nei cantieri: analisi di rischio e condizioni di impiego di macchine operatrici e mezzi di sollevamento di materiali
Nel vasto quadro delle problematiche in materia di sicurezza nelle grandi opere di cantierizzazione, caratterizzate da alti livelli di meccanizzazione, la garanzia di adeguatezza delle macchine operatrici e delle attrezzature di sollevamento si pone certamente fra le esigenze prioritarie.
La nota discute una tecnica di analisi e gestione del rischio coerente con le esigenze, logiche prima che normate, di rigore ed oggettività di analisi. Prendendo spunto da un approccio di provata efficacia, la tecnica consente di pervenire ad una verifica circa la sicurezza ed adeguatezza delle macchine allo impiego specifico, e può pertanto stabilire uno strumento utile agli analisti e ai tecnici degli Organi di Vigilanza, tanto in fase di scelte iniziali quanto in occasione di verifiche in corso d'opera.
Un esempio di applicazione del metodo -seppure sviluppato per fronteggiare un problema contingente- conferma la validitĂ generale della tecnica, a prescindere, come nel caso illustrato, dalla data di costruzione delle macchine in esame, e la sua efficacia anche quale riferimento per la identificazione di soluzioni di adeguamento realistiche e compatibili
Serum levels of soluble IL-2R, CD4 and CD8 in bronChial asthma
The aim of the present study was to compare serum levels of soluble forms of interleukin-2 receptor, CD4 and CD8, released by lymphocytes during activation of the immune system, in patients with allergic bronchial asthma, with those in healthy subjects. Significantly higher levels of soluble IL-2R and soluble CD4 were found in patients with asthma compared with the control group. In contrast, lower levels of soluble CD8 values were found in patients with asthma compared to the control group. Significant correlations were found for both sIL-2R and sCD4 and these two molecules, with lung function measured as bronchial responsiveness to inhaled methacholine. These results strengthen previous suggestions that in allergic bronchial asthma, activation of T cells plays a significant role in the disease pathogenesis
