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.

Giant cell tumor and Paget's disease of bone in one family: geographic clustering

Giant cell tumor is a rare complication of Paget's disease of bone. Typically, this tumor occurs in the case of polyostotic disease and only in pagetic bones. This tumor rarely has been seen in multiple family members who have Paget's disease, although Paget's bone disease clearly has a hereditary component. Our report documents four cases of polyostotic Paget's bone disease complicated by benign giant cell tumor. In two patients, the giant cell tumor also was multifocal. All patients were from one family. They were born in Avellino and reside in Campania, a Southern Italian region. The ancestors of the patients with familial giant cell tumor in Paget's bone disease were born in the same geographic area. These data suggest that a combination of environmental and genetic factors could be responsible for linkage of the patients born in Avellino with this neoplasm that is highly unusual in patients with Paget's disease of bone.     

Herpes Zoster Infection Following Solid Organ Transplantation: Incidence, Risk Factors and Outcomes in the Current Immunosuppressive Era

Herpes zoster (HZ) infection is a frequent and serious complication of organ transplantation that has not been examined in the current era of immunosuppression. All solid organ transplants performed between 1994 and 1999 (n = 869) at our center were analyzed to determine the incidence, complications and risk factors for developing HZ. The overall incidence of HZ was 8.6% (liver 5.7%, renal 7.4%, lung 15.1% and heart 16.8%). The median time of onset was 9.0 months. We observed high rates of cutaneous scarring (18.7%) and post-herpetic neuralgia (42.7%). Independent organ-specific risk factors included: female gender and mycophenolate mofetil therapy (liver), and antiviral treatment other than prolonged cytomegalovirus (CMV) prophylaxis (renal and heart). For all organs combined, induction therapy and antiviral treatment other than prolonged CMV prophylaxis were independent predictors for the development of HZ. Herpes zoster is common and results in significant morbidity for solid organ transplant recipients. Risk factors include induction therapy and antiviral drug therapy other than CMV prophylaxis. The latter variable identifies a subpopulation that is likely at increased risk of latent herpesvirus reactivation. The high first-year post-transplant incidence rate suggests immunization pretransplant, even in varicella zoster virus immunoglobulin seropositive individuals, may be preventative.     

Nonoperative management of iatrogenic lesions of celiac branches by using transcatheter arterial embolization

We present our experience in the nonoperative management of iatrogenic lesions of celiac branches by using transcatheter arterial embolization. We treated 6 pseudoaneurysms (5 intrahepatic and 1 of the gastroduodenal artery), 6 vessel lacerations (1 common hepatic artery, 1 right hepatic artery, 1 gastroduodenal artery, 2 pancreatoduodenal, 1 polar intrasplenic artery), 1 arterioportal fistula, and 1 arteriobiliary fistula; all the bleeding lesions were secondary to surgical, endoscopic, or interventional radiologic procedures.     

Cavernous hemangioma extending to extracranial, intracranial, and orbital regions. Case report

Extraaxial cavernous hemangiomas are rare intracranial lesions that can be located in different cranial compartments. Extension across different tissue planes such as the subcutaneous tissue, skull, orbital cavity, intracranial dura mater, and extracranial trigeminal divisions within the same patient has not been previously reported. This 32-year-old woman suffered left exophthalmos, left sixth nerve palsy, and trigeminal neuropathy. Magnetic resonance imaging studies revealed an extensive multicompartmental lesion, with enhancement following Gd administration. A left orbitopterional approach allowed removal of several cavernomatous lesions located in the orbit, frontotemporal dura, and lateral wall of the cavernous sinus. A histologically based diagnosis of extraaxial cavernous hemangioma was made. In the postoperative period the patient experienced a regression of her symptoms. The authors report on a case of cavernous hemangioma with a unique extension to different intracranial/extracranial compartments. Although radical removal of the lesion was not feasible, partial excision allowed for satisfactory clinical control of the patient's symptoms.     

Development of Diabetes Mellitus Following Kidney Transplantation: A Canadian Experience

The onset of diabetes mellitus following kidney transplantation or post-transplant diabetes mellitus (PTDM) is now recognized as being an increasingly common complication that is associated with poor graft and patient survival. The incidence and clinical correlates of PTDM in a Canadian kidney transplant population has not been examined and may vary based on differences in demographics (i.e. race). Furthermore, little information exists on the association of variables such as cumulative dose of corticosteroids and trough calcineurin inhibitor levels and PTDM. We examined all recipients of a kidney transplant in our center between 1995 and 2001 and found an overall PTDM rate of 9.8%. Five clinical factors were independently associated with PTDM: older recipient age, deceased donor, hepatitis C antibody status, rejection episode and use of tacrolimus (vs. cyclosporine). Furthermore, cumulative corticosteroid dose and calcineurin inhibitor trough level were not associated with PTDM. This study demonstrates that in a Canadian kidney transplant population that there is a significant risk of PTDM following kidney transplantation, and it is therefore advisable to minimize this risk.     

Suppression of the alveolitis in pulmonary sarcoidosis by oral corticosteroids

We evaluated the effects of daily prednisone therapy on alveolitis parameters and pulmonary function tests over a six month period in patients with active pulmonary sarcoidosis (>28% T lymphocytes in bronchoalveolar lavage and positive gallium-67 (⁶⁷Ga) lung scans). 10 patients with biopsyproven lung disease were studied. Analysis of bronchoalveolar lavage cells and of⁶⁷Ga scanning at the beginning and at the end of the study period demonstrated that prednisone treatment significantly lowered the percentages of T lymphocytes in bronchoalveolar lavage in all patients (baseline 48±3%, after treatment 19±5%, p<0.01) while⁶⁷Ga lung scans improved in 8 of the 10 patients. Pulmonary function tests showed improvement of the parameters studied (+7.5±2.1% mean change in vital capacity, +4.7±1.6% mean change in total lung capacity, +5.4±2% mean change in forced expiratory volume in one second and +6.2±1.5% mean change in diffusing capacity). In addition none of the treated patients deteriorated functionally and 9 of the 10 patients improved more than 10% in at least one parameter. These results indicate that daily oral prednisone therapy is effective in suppressing the alveolitis in pulmonary sarcoidosis and that it is able to preserve lung functions in patients who, without treatment, would be likely to deteriorate.

Relationship between deep vein thrombosis and pulmonary embolism following THA and TKA

Patients undergoing total hip arthroplasty (THA) and total knee arthroplasty (TKA) are at risk for venous thromboembolisms, including deep vein thrombosis and pulmonary embolism. Most deep vein thromboses are asymptomatic, but they can lead to long-term morbidity to the same extent as symptomatic events. The risk of complications of venous thromboembolisms depends on the location of thrombi; potential long-term complications include recurrent venous thromboembolism, postthrombotic syndrome, and chronic thromboembolic pulmonary hypertension. Risk of recurrence persists for several years after the initial event. Approximately 20% of recurrent events are pulmonary embolisms, and approximately half of those are fatal. The causal relationship between deep vein thrombosis and pulmonary embolism remains controversial. Some consider them distinct clinical entities, while others have found asymptomatic distal deep vein thrombosis to be associated with elevated risk of developing pulmonary embolism. Unique coagulation factors may be associated with orthopedic surgery patients that differentiate them from patients undergoing other types of surgery. Symptomatic and asymptomatic deep vein thrombosis can lead to the development of recurrent venous thromboembolism, pulmonary embolism, postthrombotic syndrome, and chronic thromboembolic pulmonary hypertension, all of which are associated with reduced quality of life and increased health care expenditures. Thromboprophylaxis is therefore important in patients undergoing THA or TKA. However, traditional anticoagulants are not ideal, particularly for long-term use. Orthopedic surgeons should be aware of the causes and potential sequelae of venous thromboembolism and of the new thromboprophylactic agents that can help prevent it.     

Clinical presentation and metabolic features of overt and occult urolithiasis

Although pediatricians are frequently confronted with patients presenting urolithiasis symptoms without obvious stones, the syndrome of occult urolithiasis may be still viewed with some skepticism. We have compared the clinical and metabolic features of 197 children with obvious calculi, 189 with microcalculi (diameter ≤3 mm based on renal sonography), and 114 with symptoms of urolithiasis and normal renal sonography findings. Only microcalculi and normal sonography subjects with a urinary abnormality potentially leading to urolithiasis were included in the study. Age at presentation increased significantly (p = 0.0001) in the groups in the order normal sonography to microcalculi to calculi groups. There was no significant difference among the three groups in terms of family history of urolithiasis, gender distribution, and degree of hypercalciuria, hyperuricosuria, hyperoxaluria, or hypocitraturia. The average frequency of pain attacks of patients with recurrent abdominal pain (RAP) ranged from 3.6 to 4.6 days of pain per month among the three groups, which is four to ninefold lower than that reported for children with functional or organic gastrointestinal RAP. The consistency of many clinical and urinary metabolic characteristics indicates a common underlying disorder in overt and occult urolithiasis. The increase of age at presentation from the normal sonography to microcalculi and calculi groups may reflect progressive crystal accretion leading ultimately to overt stone formation.
