A minimally invasive technique for surgical treatment of hallux valgus: simple, effective, rapid, inexpensive (SERI)

Purpose

Several bony and soft tissue procedures have been described for the treatment of hallux valgus, and currently mini-invasive surgical techniques are preferred in order to reduce surgical trauma, complications, time of surgery and to allow an earlier recovery. The aim of this study is to analyse a series of 1,000 consecutive cases of hallux valgus, surgically treated by the minimally invasive SERI technique, reporting results at mid-term follow-up.

Methods

We prospectively studied 641 patients (1,000 feet) with symptomatic hallux valgus surgically treated by SERI osteotomy. Inclusion criteria were: age between 20 and 65 years, reducible mild or moderate hallux valgus, HVA ≤ 40°, IMA ≤ 20°, and arthritis of the first metatarsophalangeal joint up to grade 2 according to the Regnauld classification.

Results

The American Orthopaedic Foot and Ankle Society (AOFAS) score rose from 46.8 ± 16.7 preoperatively to 89 ± 10.3 at last follow-up. Radiographic control at follow-up showed a complete healing of the osteotomy and remodelling of the metatarsal bone. Low rate of complication has been reported.

Conclusions

This study demonstrated that the SERI technique is effective in treating mild to moderate hallux valgus in terms of relief from symptoms and functional improvement. This technique allowed correction of the main parameters of the deformity, with durable clinical and radiographic results at a mid-term follow-up.

Cardiac consequences of hypertension in hemodialysis patients

Hypertension in end-stage renal disease (ESRD) is an important risk factor for left ventricular hypertrophy (LVH), cardiac failure, coronary artery disease (CAD), and arrhythmia. LVH is generally considered an integrator of the long-term effects of hypertension and other cardiovascular (CV) risk factors and represents the strongest predictor of adverse CV outcomes in ESRD patients. The risk of heart failure is higher in patients with a history of hypertensive renal disease than in those with other diagnoses. Both coronary heart disease (CHD) and LVH predict congestive heart failure, which is often the ultimate cause of death in patients with cardiac ischemia or LVH. A history of long-standing hypertension is associated with ischemic heart disease both in cross-sectional and prospective studies in ESRD. Atrial fibrillation and ventricular arrhythmias are highly prevalent in dialysis patients and are implicated in mortality and sudden death in this population. Despite the lack of evidence from randomized controlled trials, it appears reasonable that interventions aimed at curbing the high CV mortality of ESRD should be targeted to both hypertension and LVH.     

Laryngeal motility alteration: A missing link between sleep apnea and vagus nerve stimulation for epilepsy

This study aimed to evaluate the prevalence and the relationship of sleep breathing disorders (SBDs) and laryngeal motility alterations in patients with drug‐resistant epilepsy after vagus nerve stimulator (VNS) implantation. Twenty‐three consecutive patients with medically refractory epilepsy underwent out‐of‐center sleep testing before and after VNS implantation. Eighteen eligible subjects underwent endoscopic laryngeal examination post‐VNS implantation. Statistical analysis was carried out to assess an association between laryngeal motility alterations and the onset/worsening of SBDs. After VNS implantation, 11 patients showed a new‐onset mild/moderate SBD. Half of the patients already affected by obstructive sleep apnea (OSA) showed worsening of SBD. All of the patients with a new‐onset OSA had a laryngeal pattern with left vocal cord adduction (LVCA) during VNS stimulation. The association between VNS‐induced LVCA and SBD was statistically significant. This study suggests an association between VNS and SBD, hinting to a pivotal role of laryngeal motility alterations. The relationship between SBD and VNS‐induced LVCA supports the need to routinely investigate sleep respiratory and laryngeal motility patterns before and after VNS implantation.     

Paraurethral leiomyoma

Paraurethral leiomyoma is a rare, benign, hormone-dependent neoplasm of mesenchymal origin affecting women. The clinical evidence varies, but it tends to be asymptomatic or associated with the sensation of a foreign body; urinary symptoms are rarely described. The distinction among urethral, paraurethral, and anterior vaginal wall leiomyoma can be very difficult owing to their anatomic proximity. Excision of the mass is the recommended treatment, and the diagnosis is confirmed by the pathologic finding to rule out the presence of a sarcoma. A case of paraurethral leiomyoma associated with dysuria, dyspareunia, and obstructive voiding symptoms is reported.     

Selective release of cytokines,chemokines, and growth factors by minced skin in vitro supports the effectiveness of autologous minced micrografts technique for chronic ulcer repair

A new effective surgical procedure to repair chronic ulcers called minced micrografts technique has been recently reported. The technique consists in spreading a finely minced skin sample upon the wound bed. In this study, we investigate the in vitro release of cytokines (interleukin‐6, tumor necrosis factor‐α, interleukin‐1α, and granulocyte‐colony stimulating factor), chemokines (monocyte chemoattractant protein‐1 and growth‐related oncogene‐α), and growth factors (platelet‐derived growth factor, basic fibroblast growth factor, vascular endothelial growth factor, hepatocyte growth factor, and nerve growth factor) by minced (referred to as the minced sample) vs. not minced (referred to as the whole sample) human skin biopsy samples from the same donor. Factor release in the culture medium at different time points was detected using a multiplexed protein assay. The minced sample, which could behave like the skin fragments used in vivo in the autologous minced micrografts technique, expressed higher levels of tumor necrosis factor‐α, interleukin‐1α, platelet‐derived growth factor, and basic fibroblast growth factor, and lower levels of interleukin‐6, monocyte chemoattractant protein‐1, growth related oncogene‐α, and vascular endothelial growth factor compared with the whole sample. In conclusion, mincing of healthy skin may allow appropriate regulation of the inflammatory phase of wound healing and could induce overexpression of some growth factors, which facilitates the proliferative phase of healing.     

Preventing seroma formation after axillary dissection for breast cancer: a randomized clinical trial

BackgroundSeroma formation after axillary dissection remains the most common early sequel to breast cancer surgery. Different surgical approaches have been performed to reduce seroma collection. Therefore, we aimed to assess the outcome of patients operated on using an ultrasound scalpel according to a standardized operative technique before accepting it as a routine procedure.MethodsA randomized controlled trial was designed to compare the outcome of patients undergoing breast surgery and axillary dissection using either standard scalpel blades, scissors, ligations, and electrocautery or the ultrasound scalpel only. Each arm of the trial consisted of 30 patients.ResultsA statistically significant benefit in terms of axillary and chest wall drainage volume, the number of axilla seromas, intraoperative bleeding, and hospitalization stay was recorded in the harmonic scalpel group. No significant differences were found between the 2 groups in terms of operative time. Finally, no postoperative hematoma, wound infections, and chest wall seroma were observed.ConclusionsThe use of the harmonic scalpel was shown to reduce the magnitude of seromas in axilla and hospitalization stay. The harmonic scalpel can be used alone in axillary dissection with a safe and effective hemostasis. Our results must be confirmed by larger series.     

Renal replacement therapy in lupus nephritis

The indications and the choice of renal replacement therapy for lupus patients are similar to those for other uremic patients. However, lupus patients can pose some particular problems. First, 10-28% of patients needing dialysis can have a partial renal function recovery. Therefore, the clinician has to decide whether to administer a rescue treatment, risking side-effects, or to reduce immunosuppression precluding a potential recovery. Many patients on regular dialysis show subdued biological and clinical activity. Others can show a hectic disease activity, particularly in the 1st year. In these cases, treatment is difficult, as vigorous immunosuppression can expose uremic patients to severe side-effects. The presence of circulating antiphospholipid antibodies (aPL) can favor thrombosis or stenosis of vascular access (VA). Renal transplantation is the best therapy for most lupus patients with end-stage renal failure. Many, but not all, studies have reported similar patient and graft survival rates in lupus and in non-lupus transplant recipients. The results are much better with living donor transplantation. Patients with aPL, black patients and those on long-term dialysis have a higher graft failure risk. Candidates with active lupus and/or those with significant iatrogenic morbidity should be advised to wait 6-12 months before transplantation. The recurrence risk of lupus nephritis ranged between 2% and 30% in different studies. The histological picture does not usually show severe features. Antiplatelet agents or anticoagulation can be advised for aPL patients.     

Hyperparathyroidism associated with thyroid pathology

BACKGROUND: The pathological association between thyroid and parathyroid gland disease is here discussed. The multiphase analyzer has revealed a new type of subclinical primary hyperparathyroidism (HPP) and the role of surgery in these cases is not clear. METHODS: This is a prospective study of all cases of thyroid disease in association with parathyroid disease treated surgically in our Institute from July 1999 to June 2001. RESULTS: Of the 221 thyroidectomies carried out, 29 patients had an elevated preoperative serum level of parathyroid hormone (PTH). An ultrasonography examination was performed on all patients and a preoperative scanning with 99Tc-MIBI on 11 of 29 patients. We examined intraoperatively 19 cases of HPP (14 parathyroid adenoma, 5 hyperplasia). In 10 cases we observed a normal size of the parathyroid gland and we did not perform a parathyroidectomy. CONCLUSIONS: All patients with elevated serum parathyroid hormone and serum calcium levels before thyroidectomy should be considered candidates also for surgery to the parathyroid glands. The pathological association between thyroid and parathyroid gland diseases is not rare. We must conduct an accurate neck exploration in all these cases.     

Systemic fungemia and hepatic localizations of Fusarium solani in a liver transplanted patient: an emerging fungal agent.

The incidence of invasive fungal infection is increasing especially in the field of transplantation, affecting as many as 50% of bone marrow transplant (BMT) patients with neutropenia and 5-20% of solid-organ transplant (SOT) recipients. Fusarium species are soil saprophytes and plant pathogens. They may cause superficial mycoses or important opportunistic infections in patients with bone marrow suppression and neutropenia, they have been rarely described in solid organ recipients, and up to now there have been no reports of such infection in isolated liver transplanted patients. We describe a case of disseminated Fusarium solani infection with hepatic localization in a liver transplanted patient that resolved with the administration of amphotericin B. Our observation confirms that Fusarium spp. are emerging pathogens that may most frequently affect not only BMT patients and patients with hematological malignancies, but also SOT patients. They may cause both localized and disseminated infection. In conclusion, Fusarium spp. etiology should be considered in the context of infectious diseases following liver transplantation.     

Adjuvant treatment in the management of testis-confined germ cell tumours after orchidectomy

Germ cell tumours are highly curable, especially when still at the localized stage, which is the case for most testicular tumours. Various options are available for organ-confined disease; depending on the histological review, patients with clinical stage I seminomas can be offered radiotherapy, surveillance or chemotherapy, whereas those with clinical stage I nonseminomas can be offered retroperitoneal lymph node dissection, surveillance or chemotherapy. As it is unlikely that any of these approaches will have a clear survival advantage, the most appropriate variables to be considered are acute and late side-effects, acceptability and quality of life. In recent years adjuvant chemotherapy has been extensively evaluated in patients with seminoma or nonseminoma. In this review we discuss the advantages and disadvantages of the different strategies for treating seminomas and nonseminomas, and their associated prognostic factors, and then consider future developments.
