1/35. Medical check of competitive canoeists.We gave a sports injury questionnaire survey to 821 active canoeists, members of the japan Canoe association (JCA), and performed a medical check of 63 top competitive JCA canoeists, including physical and laboratory tests and radiographic examinations of the chest, spine, shoulder, elbow, and wrist joints. Completed questionnaires were returned by 417 canoeists, whose reported racing styles were: kayak, 324; Canadian canoe, 71; slalom, 13; and not specified, 9. Of the 417 respondents, 94 canoeists (22. 5%) reported that they experienced lumbago; 20.9% experienced shoulder pain; 3.8%, elbow pain; and 10.8%, wrist pain. On medical examinations, lumbago was found to be mainly of myofascial origin or due to spondylolysis. Impingement syndrome was also observed in 4 canoeists with shoulder problems. The competitive canoeists had low blood pressure, and some had bradycardia. On laboratory examinations, serum hemoglobulin, hematocrit, high-density lipoprotein cholesterol (HDL-CHO), creatine phosphokinase (CK), and creatine (CRTN) in the top competitive canoeists showed high values in comparison with those of an age-matched control group. However, low serum total cholesterol (TP) values were observed in the top competitive canoeists.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
2/35. Cervical flexion: a study of dynamic surface electromyography and range of motion.BACKGROUND: In the comprehensive assessment of painful conditions, dynamic surface electromyography (sEMG) and range of motion (ROM) recordings can provide information regarding muscle spasm, antalgic postures, fear of pain (protective guarding), muscle injury, and disordered movement caused by pain. This study examines ROM and sEMG patterns observed during cervical flexion. OBJECTIVE: To demonstrate 2 distinctive sEMG recruitment and dynamic ROM patterns observed during cervical flexion and return to mid-line. DESIGN: Single-subject design with independent measurement of dynamic ROM and sEMG. SETTING: Applied clinical setting. PARTICIPANTS: Two subjects with normal ROM and cervical muscles were studied. MAIN OUTCOME MEASURE: One subject was studied with sEMG. looking at the cervical paraspinals and sternocleidomastoid muscles; the other subject was studied with an active ROM device. Three cervical movements were studied: lower cervical flexion, atlantoaxial (upper) cervical flexion, and a combination upper/lower cervical flexion. RESULTS: The active ROM device indicates larger movements (higher degrees of flexion) for the lower cervical flexion compared with upper flexion. The combined movement indicates a differential movement from 2 spinal segments. The sEMG recordings indicated differential recruitment patterns. The sternocleidomastoid recruits briskly during the flexion phase of the upper cervical flexion movement, whereas the cervical paraspinals recruit briskly during return to mid-line when the lower cervical flexion is used. The combined upper then lower cervical flexion movement recruits both sets of muscles. CONCLUSIONS: The results of the study indicate 2 distinct movement patterns associated with upper versus lower cervical flexion and 2 distinct sEMG recruitment patterns. The study suggests that these 2 distinct movements involve 2 distinct cervical segments and are associated with recruitment of different muscle groups. Applied clinical research on the cervical spine should use sEMG recordings to assess both the upper and lower flexion movements as the standard for the study of cervical flexion.- - - - - - - - - - ranking = 8.1104340494594keywords = upper (Clic here for more details about this article) |
3/35. The quadriceps tendon cyst: an uncommon cause of chronic anterior knee pain.The causes of knee pain are manifold. One of the uncommon causes of chronic anterior knee pain are cysts and ganglia. magnetic resonance imaging not only reveals the intra-articular pathology but also accurately depicts such cystic structures about the knee. As part of this case report, a cyst of the lateral border of the quadriceps tendon is presented as a cause of such discomfort. Although cystic lesions around the knee are a common clinical problem, the described location is rare. After surgical revision of the lateral border of the quadriceps tendon and excision of the cyst, the patient was found to be asymptomatic.- - - - - - - - - - ranking = 69.118921102051keywords = discomfort (Clic here for more details about this article) |
4/35. An uncommon presentation of a common disease: the importance of the history in medicine.A 32-year-old recent Russian immigrant, mother of a 20-month-old son, presented with right hip pain. She had a history of peptic ulcer disease and a positive helicobacter pylori serology. Her pain was not relieved by analgesics. spine and pelvic films were unremarkable. A bone scan was consistent with metastatic disease. She underwent several diagnostic tests including computed tomography of the chest and abdomen, magnetic resonance imaging of the spine, mammogram, and breast ultrasound. A bone marrow biopsy revealed adenocarcinoma, primary site unknown. An upper endoscopy performed eight weeks after her initial presentation showed an ulcerating gastric carcinoma. She was treated with chemotherapy but died two months after diagnosis. Our patient had an uncommon presentation of a common disease. Recognizing her country of origin, and other risk factors, may have facilitated an earlier diagnosis.- - - - - - - - - - ranking = 2.1586334356371keywords = upper, chest (Clic here for more details about this article) |
5/35. familial mediterranean fever.familial mediterranean fever (FMF) is an inherited multisystem disease manifested by painful, febrile attacks affecting the chest, abdomen, joints, and skin. No simple studies confirm the presence of FMF, contributing to the difficulty in diagnosis. A 10-year-old boy initially presented with a diffuse rash and complaints of bilateral joint pain of the hips, knees, and ankles and pain of the right shoulder. The child responded to daily naproxen. One year later, he continued to complain of hip, knee, ankle, and bilateral wrist pain. He also reported mild to moderate recurrent abdominal discomfort. omeprazole provided intermittent relief. The patient continued to experience episodes of joint and abdominal pain. Two and a half years after he first presented, FMF was considered. In the second case, a 51-year-old man presented to the emergency department with complaints of fever, cough, and abdominal and joint pain. Fever, joint pain, and swelling decreased during the next few days. The patient was maintained on colchicine, with complete resolution of joint pain complaints during the next few days. colchicine, 1 to 2 mg per day taken continuously during flare and quiescent periods, is the treatment of choice for FMF. colchicine reduced the severity and frequency of attacks and may also delay or prevent secondary amyloidosis.- - - - - - - - - - ranking = 83.199034411648keywords = discomfort, abdominal pain, chest (Clic here for more details about this article) |
6/35. Potential complication of bioabsorbable screw fixation for osteochondritis dissecans of the knee.The 3 cases presented describe loosening or failure of bioabsorbable screws in the treatment of osteochondritis dissecans (OCD). In case 1, a 17-year-old boy with OCD of the medial femoral condyle was treated with bioabsorbable screw fixation. Six months after surgery, the patient had an acute episode of pain with effusion. Arthroscopic examination revealed 2 of the 4 screws backed out, causing cartilage damage to the corresponding tibial plateau. The shafts of the remaining 2 screws had completely absorbed, leaving the unabsorbed screw heads as intra-articular loose bodies in the knee. Unpredictable and inconsistent degradation of the screws is believed to be the mechanism for screw back-out and cartilage damage.- - - - - - - - - - ranking = 22.125314309431keywords = back (Clic here for more details about this article) |
7/35. giardiasis-associated arthralgia in children.BACKGROUND: giardiasis is the most common intestinal parasitosis in mexico. Usual symptoms of the acute infection are diarrhea, abdominal pain, nausea, and weight loss. Children are more frequently affected than adults. Various extra-intestinal manifestations have been reported, among which are arthritis and arthralgia. methods: A series of 10 children with arthralgia and cysts of giardia lamblia in feces seen during 13 years of private practice were presented. Ages ranged between 5 and 11 years, and 70% of the children are males. RESULTS: The joints involved in all cases were the knee and the ankle. No joint flogosis or changes in local temperature were observed. Other associated symptoms were abdominal pain (100%), abdominal distension (70%), flatulence (50%), less consistent stools (50%), anemia (30%), and increased erythrocyte sedimentation rate (60%). c-reactive protein and rheumatoid factor were negative in all cases. arthralgia disappeared after treatment with metronidazole when coproparasitoscopic analyses were negative. CONCLUSIONS: arthralgia associated with giardiasis in children is a rare entity, relatively benign, and leaves no sequelae.- - - - - - - - - - ranking = 26.160226619194keywords = abdominal pain (Clic here for more details about this article) |
8/35. HLA-B27 positive juvenile arthritis with cardiac involvement preceding sacroiliac joint changes.While cardiovascular disease develops in up to 50% of adult patients with ankylosing spondylitis, it is very uncommon in its juvenile counterpart. Regarding the early stage of the disease, before onset of sacroiliac joint changes, only two cases with aortic incompetence have been published while reports of mitral valve involvement are not available. A 13 year old boy is described with an HLA-B27 positive asymmetric oligoarthritis and enthesitis, without back pain or radiographic evidence of sacroiliitis. echocardiography showed an echogenic structure measuring 8 x 11 x 20 mm at the fibrous continuity between the aortic and mitral valves extending through a false tendon into an echogenic thickened posterior papillary muscle, causing a grade II aortic and grade I/II mitral regurgitation. Short term corticosteroid and long term non-steroidal anti-inflammatory drug and disease modifying antirheumatic drug treatments efficiently controlled the symptoms. The cardiac findings remained unchanged during a follow up of 20 months. Careful cardiac evaluation appears to be mandatory even in these young patients.- - - - - - - - - - ranking = 121.3842922524keywords = back pain, back (Clic here for more details about this article) |
9/35. Bilateral symmetric polyarthralgia revealing Fanconi's syndrome.We report the case of a 45-year-old woman who presented with a six-year history of diffuse polyarthralgia responsible for major disability. She reported bilateral symmetric arthralgia in nearly every joint, as well as back pain. Muscle wasting predominating in the roots of the limbs was found. Laboratory tests showed hypocalcemia, severe hypophosphatemia, hypokalemia, alkaline phosphatase elevation, aminoaciduria, and hyperphosphaturia, with no glycosuria. Radiographs disclosed osteolysis of the pubic symphysis, multiple pelvic fractures, vertebral compression fractures, and diffuse demineralization. A bone scan visualized symmetric foci of hyperactivity in nearly all joints and fracture sites. Dramatic improvements in clinical and radiographic abnormalities were noted after six months of treatment with phosphate and calcitriol. This is a case of incomplete fanconi syndrome, with no glycosuria. The clinical presentation of fanconi syndrome can be misleading. fanconi syndrome should be borne in mind as a possible cause of polyarthralgia to avoid diagnostic delay, which in our patient led to a picture of pseudomyopathy with multiple fractures.- - - - - - - - - - ranking = 121.3842922524keywords = back pain, back (Clic here for more details about this article) |
