Prophylactic chimera anterolateral thigh/vastus lateralis flap: preventing complications in high-risk head and neck reconstruction

2014

Purpose In high-risk head and neck cases treated with tumor resection and associated radical neck dissection, orocutaneous fistulas and wound breakdowns in the neck are relatively frequent and can have serious consequences, such as carotid blowout syndrome (CBS), the need for salvage reoperations, and prolonged recovery time. The authors present the application of a prophylactic chimeric anterolateral thigh (ALT) and vastus lateralis (VL) flap to prevent complications. Materials and Methods A retrospective review was performed of a historical group (96 patients) of patients with head and neck cancer treated with tumor resection, radical neck dissection, and microsurgical reconstruction of t…

Neck Muscle Vibration and Spatial Orientation During Stepping in Place in Humans

2002

Unilateral long-lasting vibration was applied to the sternomastoid muscle to assess the influence of asymmetric neck proprioceptive input on body orientation during stepping-in-place. Blindfolded subjects performed 3 sequences of 3 trials, each lasting 60 s: control, vibration applied during stepping (VDS), and vibration applied before stepping (VBS). VDS caused clear-cut whole body rotation toward the side opposite to vibration. The body rotated around a vertical axis placed at about arm's length from the body. The rotation did not begin immediately on switching on the vibrator. The delay varied from subject to subject from a few seconds to about 10 s. Once initiated, the angular velocity…

Central odontogenic fibroma: retrospective study of 8 clinical cases

2010

Introduction and Objectives: The central odontogenic fibroma (COF) is a benign odontogenic tumour derived from the dental mesenchymal tissues. It is a rare tumour and only 70 cases of it have been published. Bearing in mind the rareness of the tumour, 8 new cases of central odontogenic fibroma have been found by analyzing the clinical, radiological and histopathological characteristics of COF. Patients and Method: A retrospective study was carried out on 3011 biopsies in the Service of Oral and Maxillofacial Surgery of the Dental Clinic of Barcelona University between January 1995 and March 2008. 85 odontogenic tumours were diagnosed of which 8 were central odontogenic fibroma. The radiolog…

Radical surgery and different types of urinary diversion in patients with rhabdomyosarcoma of bladder or prostate--a single institution experience.

2013

Abstract Purpose In a retrospective study we analyzed the outcome of patients treated for rhabdomyosarcoma (RMS) of the bladder/prostate with special attention to radical surgery. Methods In 25 patients with genitourinary RMS (15 bladder/10 prostate) the median age at diagnosis was 4 years [1] , [2] , [3] , [4] , [5] , [6] , [7] , [8] , [9] , [10] , [11] , [12] , [13] , [14] , [15] , [16] , [17] , [18] , and 8 patients had a stage II RMS, 12 stage III and 5 stage IV. In 19/25 (12 bladder/7 prostate), radical surgery and urinary diversion were performed. Urinary diversion comprised 2 continent anal diversions, 11 continent cutaneous diversions, 4 colon conduits and 2 urethral diversions (2 +…

Permanent Stoma After Low Anterior Resection for Rectal Cancer

2010

BACKGROUND AND OBJECTIVES: A low anterior resection procedure for removing a rectal tumor aims to preserve the sphincter and avoid a permanent stoma. Permanent stomas are primarily necessary in cases of poor anorectal function and local recurrence. The aim of this study was to clarify whether anastomosis-related complications and local recurrence influenced the rate of permanent stomas in a long-term follow-up. METHODS: Of 1032 consecutive patients with rectal cancer, 397 were treated by low anterior resection (R0 and R1 resections) between 1985 and 2007 at the Department of General and Abdominal Surgery of the University Hospital, Mainz (Germany). All patient data were collected prospectiv…

Papillary Thyroid microcarcinomas: a comparative study of the characteristics and risk factors at presentation in two cancer registries

2013

Papillary thyroid microcarcinoma (PTMC) is an indolent neoplasia, often asymptomatic and discovered incidentally. Some PTMCs, however, exhibit a more aggressive behavior, frequently recur, and can even cause cancer-related death.The aim of this study was to evaluate the prevalence of PTMCs and the associated risk factors at presentation in 2 thyroid cancer registries from areas with different genetic and environmental characteristics.We conducted a retrospective, observational study of all incident cases of PTMCs recorded over a 5-year period in the Sicilian Regional Registry for Thyroid Cancer (SRRTC) and in the Surveillance Epidemiology and End Results (SEER) US registry.The study took pl…

Parathyroid Autotransplantation During Thyroid Surgery: A Novel Technique Using a Cell Culture Nutrient Solution

2016

Introduction: Parathyroid autotransplantation is an easy procedure with a low complication rate. We adopted the transplantation into the sternocleidomastoid muscle, which allows an easier and time-saving surgical procedure using the same surgical incision. Methods: In this study, we retrospectively reviewed the records of 396 consecutive patients, who underwent total thyroidectomy for benign thyroid disease. In all cases in which a parathyroid was damaged or inadvertently removed, the gland was transplanted; before the autotransplantation, the parathyroid tissue was put in a cell culture nutrient solution for 5 min, afterward fragmented, and then was transplanted in the sternocleidomastoid …

Ki-67 immunoexpression and radiological assessment of necrosis improves accuracy of conventional and modified core biopsy systems in predicting the f…

2021

Based on the French Federation Nationale des Centers de Lutte Contre le Cancer (FNCLCC) grading system, this study assesses the accuracy of conventional and modified core biopsy (CB) systems in predicting the final grade (low vs high) assigned to the resected specimen. Substituting Ki-67 immunoexpression for mitotic count, and radiological for histological assessment of necrosis, we used two modified FNCLCC CB grading systems: (1) Ki-67 immunoexpression alone, and (2) Ki-67 plus radiological assessment of necrosis. We graded 199 soft tissue sarcomas (STS) from nine centers, and compared the results for the conventional (obtained from local histopathology reports) and modified CB systems wit…

Ultrasonography for the diagnosis of Lyme disease in cases of acute facial paralysis.

1992

Ultrasonography of the parotid gland was introduced in 1989 as part of the diagnostic protocol of every patient treated in our clinics with acute facial paralysis. Ten of 50 patients so tested were found to have unilateral nonpalpable enlarged lymph nodes in the caudal portion of the parotid gland around the stylomastoid foramen. All 10 patients were eventually diagnosed as having Lyme disease. It is suggested that in patients with acute facial paralysis, ultrasonography is an inexpensive tool to improve diagnosis of Lyme disease and may have a more useful purpose in monitoring therapy.
