ABSTRACT

The aim of this systematic review and meta-analysis was to analyse the literature on the infrahyoid myocutaneous flap (IHMCF) and evaluate its clinical outcomes. The MEDLINE, Embase, Web of Science, Cochrane Library, and Scopus databases were searched (inception to December 31, 2021). Meta-analyses were then conducted to estimate the overall rates of partial flap loss, total flap loss, salivary fistula, and surgical revision. The 21 studies that met the inclusion criteria included 768 patients undergoing head and neck reconstruction with 773 IHMCF. The oral cavity (77.7%) and oropharynx (13.0%) were the most reconstructed sites. The meta-analyses estimated a pooled partial flap loss rate of 10.4% (99% confidence interval (CI) 5.4-16.7%), total loss rate of 1.8% (99% CI 0.8-3.2%), salivary fistula rate of 3.0% (99% CI 1.3-5.3%), and surgical revision rate of 1.9% (99% CI 0.7-3.7%). Fast flap harvesting and low donor site morbidity were other flap features. Previous thyroid surgery or neck dissection and advanced lymph nodal stage were considered contraindications to IHMCF reconstruction by most authors, while prior neck radiotherapy was reported as a relative contraindication. This pedicled cervical flap is a versatile and reliable reconstructive option for medium-sized head and neck defects. Careful preoperative assessment of the neck condition allows for its safe use.

ABSTRACT

PURPOSE: Early persistent/recurrent hypopharyngeal tumours represent a challenge for surgeons who have to balance the need for oncological radicality and the desire to maintain a functioning larynx with preservation of the patient's quality of life. The aim of this study was primarily to understand the technical feasibility, functional outcomes, and the possibility of obtaining oncological radicality using lateral hypopharyngectomy with laryngeal preservation in early recurrent post-radio/(chemo)therapy hypopharyngeal tumours. METHODS: Patients with recurrent T1 hypopharyngeal squamous cell carcinoma were retrospectively selected from our institutional database. The external lateral approach according to Spriano and a modified lateral hypopharyngectomy with laryngeal preservation were used to resect tumours of the lateral pyriform sinus wall. Reconstruction was obtained by direct approximation of the posterior border of the sectioned thyroid cartilage to the posterior hypopharyngeal wall, and this was reinforced with a second layer of vascularised and non-irradiated tissue that was provided by a microvascular fascial anterobrachial flap. Swallowing was assessed 3 weeks after surgery using videoendoscopic evaluation. RESULTS: The surgical procedure was technically feasible, and complete resection was obtained in all patients. None of the patients experienced major post-operative complications (salivary fistula, bleeding, aspiration pneumonia). Mild dysphagia was observed in one patient who underwent swallowing rehabilitation. Tracheostomy was closed in all patients. No recurrence was recorded after a median follow-up of 20 months. CONCLUSION: The reported experience shows that, in selected cases, it is possible to radically remove lateral hypopharyngeal cancer with acceptable functional results.

ABSTRACT

The aim of this study was to evaluate the feasibility of microvascular anastomosis using a 4K three-dimensional exoscope system (VITOM 3D) in 10 consecutive cases of free flap head and neck reconstructive surgery. This was a clinical human study of free flap microvascular anastomosis using a VITOM 3D exoscope in 10 consecutive patients undergoing reconstruction after ablative surgery for head and neck carcinoma. Microvascular anastomoses were performed successfully using the exoscope in all patients, without any need for the conventional microscope. Arterial anastomoses were all end-to-end. Venous anastomoses were end-to-end in eight cases and end-to-side with the internal jugular vein in two cases. This study demonstrates the technical feasibility of microvascular anastomosis using a 4K three-dimensional exoscope system (VITOM 3D) in a series of 10 cases.

ABSTRACT

OBJECTIVES: This study was aimed at searching noninvasive markers of the transition from mild to severe fibrosis stage in HCV patients undergoing hepatic fibrosis. DESIGN AND METHODS: Thirty-three patients affected by chronic HCV vs. twenty healthy donors were evaluated for the serum levels of several circulating matrix metalloproteinases (MMPs), TRAIL and ß-NGF by multiplex biometric ELISA based immunoassay and anti- and pro-oxidant status (d-ROMs, BAP and NO) using a Diacron automated method. RESULTS: HCV patients displayed increased expression levels of MMP-8, MMP-9, TRAIL and ß-NGF, and an imbalance between pro- and antioxidant status, that contribute to liver fibrosis. CONCLUSIONS: Since the determination of these parameters represents a reliable and easily applicable method, these parameters are suggested as serum surrogate markers for HCV patients in the routine clinical practice.

ABSTRACT

Bacterial infections are the most frequent cause of hospitalization in elderly patients. In the early eighties, the advantages of Outpatient parenteral Antibiotic therapy (OPAT) were identified in the United States, and suitable therapeutic programs were established. In order to understand the different ways of managing OPAT, a National OPAT Registry was set up in 2003 in Italy. This study analyzes data concerning bacterial infections in 176 elderly patients including demographics, therapeutic management, clinical response, and side-effects. Bone and joint infections (48.9%) and skin and soft tissue infections (27.8%) were the most common infections treated with OPAT. Teicoplanin (28.9%) and ceftriaxone (22.1%) were the top two antibiotics chosen. OPAT was mainly performed at a hospital infusion center (52.8%). The clinical success rate was high and side-effects were low (12.6% of cases). Management of bacterial infections in the elderly with an outpatient program is effective and safe.

ABSTRACT

In the early eighties, the advantages of outpatient parenteral antibiotic therapy (OPAT) (reduced costs, no hospitalization trauma in children, no immobilization syndrome in elderly, reduction in nosocomial infections by multiresistant organisms) were identified in the United States, and suitable therapeutic programs were established. Currently, more than 250,000 patients per year are treated according to an OPAT program. In order to understand the different ways of managing OPAT and its results, a National OPAT Registry was set up in 2003 in Italy. Analysis of data concerning osteomyelitis, septic arthritis, prosthetic joint infection and spondylodiskitis, allowed information to be acquired about 239 cases of bone and joint infections, with particular concern to demographics, therapeutic management, clinical response, and possible side effects. Combination therapy was the first-line choice in 66.9% of cases and frequently intravenous antibiotics were combined with oral ones. Teicoplanin (38%) and ceftriaxone (14.7%), whose pharmacokinetic/pharmacodynamic properties permit once-a-day administration, were the two top antibiotics chosen; fluoroquinolones (ciprofloxacin and levofloxacin) were the most frequently utilized oral drugs. Clinical success, as well as patients' and doctors' satisfaction with the OPAT regimen was high. Side-effects were mild and occurred in 11% of cases. These data confirm that the management of bone and joint infections in an outpatient setting is suitable, effective and safe.

ABSTRACT

The aim of the study was to evaluate the incidence of post-surgical infections and to assess management of antibiotic surgical prophylaxis. The survey was carried out by means of a questionnaire in order to obtain diverse information such as demographics, length of pre- and post-operative hospitalization, type of surgery, intervention duration, possible antibiotic prophylaxis and onset of post-surgical infections also monitored by post-discharge ambulatory controls. Four General Surgery and five Obstetrics and Gynecology Departments in Campania (southern Italy) participated in the study, which was carried out from December 2001-January 2002. Overall, 410 questionnaires were collected, referring to as many patients; antibiotic prophylaxis was performed in 385 (93.9%) patients. Antibiotic prophylaxis was generally managed not according to the general principles suggested by the international guidelines either for timing, for its duration or for the route of administration. Substantial differences were also noted in patient selection and antibiotic choice. Surgical site infections were recorded in 0.9% of patients undergoing clean surgery and in 3.6% of patients undergoing clean-contaminated surgery. Distant infections occurred in 1.5% in clean-contaminated surgery. The results of the present study suggest the need for continuous and accurate monitoring of post-surgical infections and the need to adopt appropriate guidelines to improve the management of surgical prophylaxis.

ABSTRACT

BACKGROUND: The discussion about the pathogenesis of renal anaemia, whether it is primarily due to relative erythropoietin (Epo) deficiency or to uraemic inhibition of erythropoiesis, is still open. Although it has so far not been possible to identify or isolate a substance retained in uraemia with a suppressive action directed specifically against red-cell production, dialysis therapy can improve the effect of both residual endogenous Epo and exogenous rHuEpo. To what extent the mode and/or the dose of dialysis influence Epo efficacy is as yet poorly understood. METHODS: This study was performed as a single-centre trial. The protocol included a run-in period of 4 months followed by a prospective cross-over study including 6 months each of acetate-free biofiltration (AFB) with a high-flux biocompatible membrane and standard bicarbonate dialysis (BD) with a low-flux cellulosic membrane in a random sequence. AFB is a haemodiafiltration technique based on a continuous post-dilution infusion of a sterile isotonic bicarbonate solution. At the start of the run-in period (and for the entire length of the study), rHuEpo administration was withdrawn; patients whose haemoglobin (Hb) levels dropped at a level <8.0 g/dl at one single monthly check, had to be withdrawn from the study. A blood sample was collected every month for the blood gas analysis and for the determination of blood urea nitrogen, serum creatinine, sodium, potassium, calcium, phosphorus, Hb, erythrocyte, reticulocyte, leukocyte and thrombocyte cell counts, mean globular volume and haematocrit. An equilibrated single pool Kt/V(urea)>1.2 was mandatory in both treatment modalities. Serum iron, total iron-binding capacity, and ferritin were checked every 3 months. RESULTS: Twenty-three of 137 haemodialysis patients were considered eligible for the trial on the basis of the entry criteria. Of these, 15 volunteered and only 10 completed the study. No significant differences in the haematological indices, in the biochemical parameters assessing body iron stores, or in i.v. iron dosage was observed when comparing AFB with BD treatments. The equilibrated single pool Kt/V(urea) was always >1.2 and in no case was a significant difference observed when comparing AFB with BD treatments. Treatment time was significantly different between the two treatments (262+/-2 min in BD and 249+/-1 in AFB, P<0.0001). Neither pre- nor post-dialysis systolic and diastolic blood pressures, pre-dialysis serum bicarbonate and pH, pre-dialysis serum sodium, potassium, calcium, or phosphorus were significantly different when comparing the two treatment modalities. All 10 patients completed the 1-year follow-up without any major side-effects. CONCLUSIONS: Our study did not show any improvement of anaemia when treating a highly selected patient group, in the absence of any Epo therapy, with AFB compared with standard BD. Even though these conclusions cannot be extended in toto to the entire dialysis population, in which there is a large proportion of Epo-treated patients with Hb levels around 11 g/dl, we may nevertheless conclude that when patients are well selected, adequately dialysed, and not iron- and/or vitamin-depleted, the effect of a haemodiafiltration technique with a high-flux biocompatible membrane is less than might be expected from the results of uncontrolled studies.

ABSTRACT

The authors analysed retrospectively the clinical and laboratory features of patients hospitalised in a unit of infectious diseases in the period from 1996-99. In particular, the etiology, the antimicrobial susceptibility of responsible microorganisms, criteria utilized for diagnosis, antibiotic courses and outcomes were evaluated and discussed. Echocardiography is an essential tool in the diagnosis. Infective endocarditis remains a serious infection and is still associated with high morbidity and mortality rate, despite appropriate treatment. Seriously ill patients may require prompt surgery.

ABSTRACT

The authors evaluated the efficacy and safety of an OPAT program in a small group of patients affected by infective endocarditis. Three patients were considered eligible for the treatment; i.e. they had a stable hemodynamic balance and no embolic events. Streptococcus spp. grew in blood cultures of two patients, while blood cultures were negative in the third patient. Long-acting antibiotics were used and all patients recovered from the infection without adverse events. The treatment was efficacious and safe. This preliminary experience suggests that OPAT programs can be promoted in infective endocarditis with advantage. Strictness and caution are necessary in screening and monitoring patients.

ABSTRACT

BACKGROUND: Patients with acute and chronic hepatitis B virus infection have elevated serum levels of soluble interleukin-2 receptor. This study examined patients with chronic hepatitis C virus infection to determine whether serum soluble interleukin-2 receptor levels were elevated and whether the degree of these elevations in serum levels correlated with histologic severity of hepatitis-related liver injury. METHODS: Percutaneous liver biopsies were performed on 123 patients with chronic hepatitis C virus infection. Serum levels of soluble interleukin-2 receptor in these 123 patients were measured by means of specific enzyme-linked immunoassay and were compared with levels in 174 subjects in a hepatitis-free control group. RESULTS: Soluble interleukin-2 receptor levels were significantly higher in the patients with hepatitis C than in subjects in a control group (p < 0.0001). A progressive and significant increase occurred in soluble interleukin-2 receptor levels with increasing severity of liver injury (p < 0.001). The highest levels of soluble interleukin-2 receptor occurred in patients who had hepatocellular cancer. CONCLUSIONS: Soluble interleukin-2 receptor levels correlate with the histologic severity of liver damage in patients with chronic hepatitis C virus infection and may be useful as a marker in patients at high risk of getting hepatocellular cancer.

ABSTRACT

An open, randomized clinical study was carried out to compare the clinical efficacy and safety of pefloxacin with that of chloramphenicol in the treatment of typhoid fever. Sixty hospitalized patients (40 men and 20 women, aged from 17 to 64 years), affected by severe proven typhoid sepsis, were randomly assigned to treatment with pefloxacin at a daily dose of 1,200 mg for 15 days (Group A) or with chloramphenicol at a daily dose of 2 g for 15 days (Group B). The two groups of patients were statistically homogeneous regarding both age and sex and all patients were followed for 30 days after the end of therapy. In Group A all the patients completely recovered from infection and all the isolated strains of Salmonella typhi were eradicated by pefloxacin treatment. In Group B two patients had a relapse, two patients became chronic enteric carriers of S. typhi and only 26 patients recovered from infection with complete eradication of the pathogen. The results indicate that pefloxacin is as active as chloramphenicol in the therapy of typhoid fever and that pefloxacin could be a valid antibacterial agent to be used together with appropriate hygienic measures for an eradication program of typhoid fever in the endemic countries.

ABSTRACT

The investigation on several forms of uremic osteodystrophy by means of bone mineral content (BMC) measurement led to contradictory conclusions. BMC in 27 patients on periodical hemodialysis treatment was measured correlating it to the seric levels of Ca, P, Mg, alkaline phosphatase (AP), calcitonin (Ct), osteocalcin (BGP), intact parathormone (PTHi), c-terminal and mean molecule PTH. Patients on dialysis treatment from a long period of time showed high AP and low BMC levels. This correlation proved significant just for the values recorded at a third distal site of radius. Patients with BMC under the normal range showed higher BGP levels and a longer period of dialytic treatment than those presenting normal BMC. The former showed a Ct inverse correlation as to age and mineralization indexes. Higher values of Ct and BMC have been reported in males rather than in females. Hence BMC is not suited to investigate different kinds of uremic osteodystrophy. Seric PTH dosage is certainly best fitted to discriminate patients affected with hyperparathyroidism from those with low turnover osteodystrophy. BMC determination is a valid support to evaluate the bone mineral loss in patients on haemodialysis treatment. It significatively correlates to the duration of the dialytic treatment; it is higher in female than in male population; it mainly affects cortical components rather than trabecular ones and is related to a seric Ct decrease.
