Arthralgia as an early extraintestinal symptom of Whipple's disease. Report of five cases.
1997
Five patients with Whipple's disease all suffered from arthralgia for a long time (15 years in one case) before developing gastrointestinal or other symptoms. In all patients, arthralgia was seronegative, and there was no evidence of joint destruction. Arthralgias were symmetric and migrating. Whipple's disease is part of the differential diagnosis of enteropathic arthralgia. Thereby, the polymerase chain reaction can be a helpful tool to prove Whipple's disease in difficult differential diagnosis.
Estrogen metabolism modulates bone density in men.
2007
Estrogen is a critical hormone for bone homeostasis in men, but no information is available on the role of estrogen metabolism among men. The aim of this study was to evaluate the effect of estrogen hydroxylation on male bone mineral density (BMD). Participants consisted of 61 healthy Caucasian males (mean age 66.6 +/- 1.0 years). Urinary estrogen metabolites were measured by enzyme-linked immunosorbent assay, serum estradiol by ultrasensitive radioimmunoassay, sex hormone binding globulin by radioimmunoassay, and BMD of the lumbar spine and the proximal femur by dual-energy X-ray absorptiometry. Active estrogen metabolites, 16alpha-hydroxyestrone (16alphaOHE(1)) and estriol (E(3)), positiv…
Leg and joint stiffness in human hopping
2010
The present study investigated the regulation of leg and joint stiffness in hopping at different intensity levels. Eight male subjects performed bilateral hopping at various intensity levels that were determined by peak vertical ground reaction force (GRF). In addition to the GRF, the measurements included hopping kinematics and electromyography (EMG) of selected leg muscles. While the leg and ankle joint stiffness remained invariant, the knee joint stiffness increased significantly (P<0.01) with the hopping intensity. EMG analysis revealed a significant increase in averaged EMG for all the measured muscles before and during the early phase of ground contact (P<0.05-0.001) with increasing h…
Anatomy of the Sacral Roots and the Pelvic Splanchnic Nerves in Women Using the LANN Technique
2007
AIMS: To report on our anatomic and electrophysiologic findings about the sacral nerve roots and the pelvic splanchnic nerves during laparoscopic pelvic surgery. METHODS: The pelvic splanchnic nerves and the sacral nerve roots were dissected in 336 consecutive patients undergoing laparoscopy for pelvic pain syndrome or gynecologic diseases. Intraoperative assessment of the functionality of the exposed nerves was performed using the LAparoscopic Neuro-Navigation (LANN) technique. RESULTS: Dissection of the sacral roots and the splanchnic pelvic nerves lateral to the sacral hypogastric fascia was feasible without any complications in all patients in this series. The mean surgical time was 16 …
Dynamic Gait Parameters in Patients With Nonunion of the Tibia Following Treatment With the Ilizarov Method.
2020
Abstract The purpose of this study was a comprehensive assessment of the dynamic parameters of gait in patients who underwent Ilizarov treatment for nonunion of the tibia. The experimental group consisted of 24 individuals treated with the Ilizarov method for nonunion of the tibia. The control group comprised 31 healthy individuals, matched for BMI, sex, and age. The dynamic gait parameters in patients and in the control group were measured with a Zebris pedobarographic platform. The treatment group and the control group showed statistically significant differences in terms of the following gait parameters: maximum force during braking nonoperated-limb (NOL), time maximum force during braki…
MRI evaluation to predict tendon size for knee ligament reconstruction.
2017
Background The aim of this study is to evaluate a possible correlation between specific anthropometric parameters and sizes of knee tendons commonly used for ACL reconstruction. We hypothesized that specific clinical and radiological knee measurements could be better tendon sizes predictors than age, gender, height and weight. Materials and methods 100 consecutive patients were enrolled and 77 patients met the inclusion criteria of the study. All patients underwent a MRI of the knee with a 1.5 T super conducting MR System. For each patient, anthropometric data such as gender, height, weight, body mass index (BMI) and knee circumference were recorded. Specific MRI knee measurements were perf…
Radial Head Fractures
2014
Radial head fractures are the most common elbow fractures, accounting for 20–30 %. Typically, the fractures evolve from a fall on the outstretched hand with the elbow extended and the forearm in pronation. The role of the radial head as an important stabilizer of the elbow joint has been recognized in the last decade. Sixty percent of the axial load transmitted through the elbow is conducted through the radial head. Furthermore, the radial head is an important stabilizer against valgus stresses. While the medial collateral ligament (MCL) is the primary stabilizer against valgus stress, the role of the radial head emerges when the MCL is torn. These findings have led to a change in treatment…
Iliosacral Screw Osteosynthesis
2017
Fragility fractures of the anterior pelvic ring are very often combined with fractures of the posterior pelvic ring. The large majority of the posterior fractures is situated in the sacral ala. Non-operative therapy may be cumbersome in patients with a combination of an anterior with a posterior pelvic ring fracture. Any surgical therapy should be as less invasive as possible. Iliosacral screw fixation is a minimal invasive technique. Variations of the upper sacral anatomy make optimal iliosacral screw placement challenging. The vestibule or isthmus is the narrowest part of the bony corridor from the lateral ilium to the S1 sacral body. It always points towards anterior and superior. The wh…
Unusual manifestation of an osteoid osteoma of the capitate.
1999
A case of osteoid osteoma of the capitate in a 29-year-old male is reported. The patient suffered from unspecific clinical findings and a 3-year history of uncharacteristic wrist pain. Conventional radiographs of the wrist revealed a circumscribed sclerosis in the proximal part of the capitate bone beside a diffuse demineralisation of the carpal bones. Magnetic resonance imaging demonstrated a circumscribed, tumorous lesion with marked enhancement after IV administration of contrast agent and a highly calcified nidus, which was sharply demarcated by a small rim of granulation tissue from the surrounding spongious bone. Based on MRI findings, the diagnosis of an osteoid osteoma was establish…
Glucocorticoid-sensitive hereditary inclusion body myositis.
1996
We report a hereditary muscle disorder with features of inclusion body myositis (IBM) in two adult sisters with slowly progressive asymmetrical muscle weakness. The findings of light microscopic and ultrastructural investigations of muscle biopsy specimens were consistent with a diagnosis of IBM. Both patients improved and stabilized on immunosuppressive treatment with corticosteroids and azathioprine. This differentiates our patients from other sporadic and familial cases of IBM. Clinical and histological features are described and compared with those of other previously reported families with IBM.
