CASE: A 19-year-old woman sustained a plantar flexion-inversion injury to her right ankle after a low-speed motor vehicle collision. Clinical examination demonstrated supinated, adducted deformity of the foot, and prominent calcaneus laterally. Radiographs revealed dislocation of the calcaneocuboid joint, a rare injury, which was successfully stabilized by a novel technique using a hamstring allograft. The presentations and clinical and surgical management of this rare condition are discussed...

CASE: A 42-year-old man presented with distal radius fracture. We performed external fixation combined with Kirschner wiring, which was removed 6 weeks postoperatively. After the removal of the implants, the patient could not achieve any pronation-supination, and distal radioulnar synostosis became apparent during the follow-up. The patient underwent distal ulnar osteotomy, and 60° pronation and full supination were achieved. No complications were reported at the 32-month follow-up. CONCLUSION: This is a rare case of radioulnar synostosis after percutaneous fixation surgery for distal radius fracture...

Autonomic dysfunction is a common condition in the alpha-synucleinopathies (Parkinson's disease, dementia with Lewy bodies, multiple system atrophy). Cardiovascular symptoms may include orthostatic hypotension, supine hypertension or decreased heart rate response. A clinical suspicion and physical examination are essential for diagnosis, taking blood pressure in supine and standing positions. The electrocardiogram may show a prolongation of the PR and QT intervals, while 24-hour ambulatory blood pressure monitoring provides information on blood pressure patterns...

INTRODUCTION: More than a quarter of tumors are missed by magnetic resonance imaging/ultrasound (MRI/US) fusion-guided biopsy, the majority due to software-based mis-registration. Transrectal approaches to biopsy are typically performed in the lateral decubitus position; conversely, diagnostic MRI is performed with the patient lying supine. Any position-related difference in prostate location or gland deformation could potentially exacerbate mis-registration at subsequent biopsy. METHODS: Fifteen healthy male volunteers (mean age 35...

BACKGROUND: The biceps tendon is a known source of shoulder pain. Few high-level studies have attempted to determine whether biceps tenotomy or tenodesis is the optimal approach in the treatment of biceps pathology. Most available literature is of lesser scientific quality and shows varying results in the comparison of tenotomy and tenodesis. PURPOSE: To compare patient-reported and objective clinical results between tenotomy and tenodesis for the treatment of lesions of the long head of the biceps brachii...

Failure to recognize symptoms of orthostatic hypotension (OH) may result in falls, syncope, and injuries. The relationship between orthostatic changes in blood pressure and symptom occurrence and severity is not known. The goal of the present study was to define the relationship between the occurrence and severity of the symptoms of orthostatic hypotension (OH) and (1) the upright systolic blood pressure (SBP) and (2) the fall in SBP after tilting in patients with OH. We prospectively studied 89 patients with OH...

PURPOSE: Propofol clearance can be reduced when cardiac output (CO) is decreased. This clearance reduction may alter the pharmacokinetics of propofol and worsen the predictive performance of target-controlled infusion (TCI) of propofol. The head-down position (HDP) and CO2 pneumoperitoneum, which are required for robotic-assisted laparoscopic prostatectomy (RALP), may cause changes in CO. We investigated the predictive performance of propofol TCI during CO2 pneumoperitoneum in patients who underwent RALP in the HDP...

BACKGROUND AND AIMS: It still remains controversial how often the once-accepted radiological alignment of an AO type-C distal radius fracture deteriorates after conservative treatment, and to what extent this deterioration is perhaps associated with patient-rated outcome measures (PROms). Thus, we aimed to evaluate this radiological deterioration and its association with mid-term functional follow-up. PATIENTS AND METHODS: We retrospectively reviewed 66 patients (mean age at fracture 53 years, SD 14...

Autonomic nervous system (ANS) activity and imbalance between its sympathetic and parasympathetic components are important factors contributing to the initiation and progression of many cardiovascular disorders related to obesity. The results on respiratory sinus arrhythmia (RSA) magnitude changes as a parasympathetic index were not straightforward in previous studies on young obese subjects. Considering the potentially unbalanced ANS regulation with impaired parasympathetic control in obese patients, the aim of this study was to compare the relative contribution of baroreflex and non-baroreflex (central) mechanisms to the origin of RSA in obese vs...

BACKGROUND: Midfoot joint impairment is likely following lateral ankle sprain (LAS) that may benefit from mobilization. OBJECTIVE: To investigate the effects of midfoot joint mobilizations and a one-week home exercise program (HEP) compared to a sham intervention and HEP on pain, patient-reported outcomes (PROs), ankle-foot joint mobility, and neuromotor function in young adults with recent LAS. METHODS: All participants were instructed in a stretching, strengthening, and balance HEP and were randomized a priori to receive midfoot joint mobilizations (forefoot supination, cuboid glide and plantar 1st tarsometatarsal) or a sham laying-of-hands...

BACKGROUND AND OBJECTIVES: Sleep-disordered breathing (SDB) affects up to one third of women during late pregnancy and is associated with adverse pregnancy outcomes, including hypertension, diabetes, impaired fetal growth, and preterm birth. However, it is unclear if SDB is associated with late stillbirth (≥28 weeks' gestation). The aim of this study was to investigate the relationship between self-reported symptoms of SDB and late stillbirth. METHODS: Data were obtained from five case-control studies (cases 851, controls 2257) from New Zealand (2 studies), Australia, the United Kingdom, and an international study...

Patients with staghorn renal stones are challenging cases, requiring careful preoperative evaluation and close follow-up to avoid stone recurrence. In this article we aim to discuss the main topics related to staghorn renal stones with focus on surgical approach. Most of staghorn renal stones are composed of struvite (magnesium ammonium phosphate) and are linked to urinary tract infection by urease-producing pathogens. Preoperative computed tomography scan and careful evaluation of all urine cultures made prior surgery are essential for a well-planning surgical approach and a right antibiotics choice...

Baroreflex response consists of cardiac chronotropic (effect on heart rate), cardiac inotropic (on contractility), venous (on venous return) and vascular (on vascular resistance) arms. Because of its measurement simplicity, cardiac chronotropic arm is most often analysed. The aim was to introduce a method to assess vascular baroreflex arm, and to characterize its changes during stress. We evaluated the effect of orthostasis and mental arithmetics (MA) in 39 (22 female, median age: 18.7 yrs.) and 36 (21 female, 19...
