Diagnosis of Groin Pain Associated With Sports Hernia Using Dynamic Ultrasound and Physical Examination: A Case Report

Groin pain in athletes is a complex diagnostic and therapeutic challenge. Sports hernia is one of the common causes of groin pain. We report a case of sports hernia, initially presented as groin pain and aggravated by sports activity. A 19-year-old soccer player visited the outpatient department of general surgery and was referred to the rehabilitation center due to no abnormalities detected in the abdomen and pelvis by computed tomography. An incipient direct bulge of the posterior inguinal wall was detected with dynamic ultrasound when abdominal tension was induced by raising both legs during a full inhalation. Surgery was performed and preoperatively both groins showed the presence of inguinal hernia. Diagnosing sports hernia is very challenging. Through careful history documentation and physical examination followed by dynamic ultrasonography, we identified his posterior inguinal wall deficiency for early management.

The Relationship between Cross Sectional Area and Strength of Back Muscles in Patients with Chronic Low Back Pain

OBJECTIVE: To evaluate the relationship between the cross sectional area (CSA) and isokinetic strength of the back muscles in patients with chronic low back pain. METHOD: Data of twenty-eight middle-aged patients with chronic back pain were analyzed retrospectively. CSAs of both paraspinal muscles and the disc at the L4-L5 level were measured in MRI axial images and the relative CSAs (rCSA: CSA ratio of muscle and disc) were calculated. The degree of paraspinal muscle atrophy was rated qualitatively. Isokinetic strengths (peak torque, peak torque per body weight) of back flexor and extensor were measured with the isokinetic testing machine. Multiple regression analysis with backward elimination was used to evaluate relations between isokinetic strength and various factors, such as CSA or rCSA and clinical characteristics in all patients. The same analysis was repeated in the female patients. RESULTS: In analysis with CSA and clinical characteristics, body mass index (BMI) and CSA were significant influencing factors in the peak torque of the back flexor muscles. CSA was a significant influencing factor in the peak torque of total back muscles. In analysis with rCSA and clinical characteristics, BMI was significant in influencing the peak torque of the back flexors. In female patients, rCSA was a significant influencing factor in the peak torque per body weight of the back flexors, and age and BMI were influencing factors in the peak torque of back flexors and total back muscles. CONCLUSION: In middle-aged patients with chronic low back pain, CSA and rCSA were influencing factors in the strength of total back muscles and back flexors. Also, gender and BMI were influencing factors.

Arteriovenous Malformation Incidentally Found by Ultrasonography in a Thigh Hematoma after Contusion

Vascular malformations in extremities are difficult to detect in cases of minor trauma. The authors report a case of an arteriovenous malformation (AVM) incidentally found by ultrasonography in a contusion. After a slip down, a 52-year-old man who had undergone total arthroplasty in both hips 10 years earlier complained of an ovoid right hip swelling that had gradually increased in size. Suspecting a simple cyst or hematoma, the swelling was examined by ultrasonography, which revealed a subcutaneous hematoma with arterial flow connected to muscle. Arteriography revealed an AVM around the right hip joint. Due to the presence of multiple arteriovenous shunts, a conservative treatment course was adopted and after 3 weeks of treatment the swelling almost completely resolved. It appears that the small AVM may have existed congenitally before hip surgery and the contusion over the AVM had led to hematoma rather than an arteriovenous fistula. The authors emphasize the usefulness of ultrasonography for the diagnosis of posttraumatic swelling.

Dysphagia due to Retropharyngeal Abscess that Incidentally Detected in Subarachnoid Hemorrhage Patient

Cerebral hemorrhage is one of the most common causes of dysphagia. In many cases, dysphagia gets better once the acute phase has passed. Structural lesions such as thyromegaly, cervical hyperostosis, congenital web, Zenker's diverticulum, neoplasm, radiation fibrosis, and retropharyngeal abscess must be considered as other causes of dysphagia as well. Retropharyngeal abscess seldom occur in adults and if it does so, a search for a prior dental procedure, trauma, head and neck infection is needed. The symptoms may include neck pain, dysphagia, sore throat, and in rare cases, dyspnea accompanied by stridor. We present a case and discuss a patient who had dysphagia and neck pain after a cerebral hemorrhage. Testing revealed a retropharyngeal abscess. The symptoms were successfully treated after the administration of antibiotics.

Dysphagia in Ramsay Hunt's Syndrome: A Case Report

Ramsay-Hunt syndrome is caused by varicella zoster virus infection in the geniculate ganglion of the facial nerve. It is characterized by facial palsy, otic pain, and herpetic vesicles around the auricle and external auditory canal. Additionally, symptoms may develop related to other cranial nerve involvement, such as dizziness or hearing loss by the vestibulocochlear nerve being invaded. We report a rare case of a Ramsay-Hunt syndrome patient who developed dysphagia due to multiple cranial nerve involvement including the glossopharyngeal nerve and vagus nerve.

Causes of the Hemiplegic Shoulder Pain

OBJECTIVE: To find out how many causes constitute hemiplegic shoulder pain (HSP) and how they distribute in an individual patient. METHOD: Twenty-three consecutive patients with HSP which had newly developed within 3 months after stroke were enrolled from January 2008 till July, 2008. They all performed a passive range of motion test for adhesive capsulitis, modified Ashworth test for spasticity, simple x-ray for subluxation, ultrasonography for rotator cuff problems and three-phase bone scintigraphy for complex regional pain syndrome (CRPS). The causes of HSP were analyzed in number and distribution. RESULTS: Average 2.26 causes constituted with HSP in an individual patient. Most common causes were adhesive capsulitis and CRPS (respectively 14 patients). Two patients had 4 and eight patients had 3 types of shoulder pathology. CONCLUSION: More than two types of shoulder pathology existed in a patient with HSP. These findings shoulde be carefully considered when treating the patients with HSP.

The Influence of Depressive Symptoms on Cognitive and Functional Recovery in Chronic Stroke Patients

OBJECTIVE: To investigate the influence of depressive symptoms on cognitive and functional recovery in chronic stroke patients. METHOD: Seventy-four chronic stroke patients were included. They had inpatient rehabilitation program for 2 months. Depressive symptoms were evaluated with the Beck depression inventory (BDI), cognitive functions by the Korean mini-mental status examination (MMSE-K) and functional status by the modified Barthel index (MBI) before and after the rehabilitation. We investigated whether the improvement of depressive symptoms after rehabilitation had influenced the cognitive and functional recovery, by comparing the changes of MMSE-K and MBI in patients with depressive symptoms. RESULTS: Before inpatient rehabilitation program, patients with depressive symptoms had low scores of MMSE-K and MBI compared to those without. While patients with depressive symptoms had significant improvement of MMSE-K after rehabilitation (p<0.05), those without did not. Both groups with and without depressive symptoms had significant improvement of MBI after rehabilitation, but the changes of MBI were not different significantly. Among patients with depressive symptoms at admission, those who showed improved depression after rehabilitation had the significant improvement of MMSE-K after rehabilitation (p<0.05), but those with sustained depressive symptoms did not. CONCLUSION: Post-stroke depressive symptoms may influence on cognitive function. However, post-stroke depressive symptoms did not have any effect on functional recovery.

Ulnar Neuropathy within Guyon's Tunnel in a Golf Player : A case report

One of common injury sites in golfers is the wrist, but ulnar neuropathies at wrist in golfers have been rarely reported. We report a case of ulnar neuropathy within the Guyon's tunnel occurred in a single golfer diagnosed with electrodiagnosis and ultrasound. A 59-year old man suffered from difficulty with extension of left 4th and 5th finger joints and weakness of hand grasping, which had occurred 2 weeks ago and aggravated slowly. He had no sensory disturbance. During recent two months, he had practiced golf for three to four hours daily. Electrodiagnostic study showed that the deep branch of left ulnar nerve was compromised at the wrist (type IIA). Ultrasound study revealed a ganglion cyst within the Guyon's tunnel. Therefore we diagnosed the patient as having ulnar neuropathy (only deep branch involvement) associated with a ganglion cyst within the Guyon's tunnel.

A Case of Combined Compressive and Vitamin B12 Deficient Myelopathy: A case report

Vitamin B12 deficiency can cause myelopathy of subacute combined degeneration of lateral and dorsal column in spinal cord. When combined with compressive myelopathy, symptoms and signs of vitamin B12 deficient myelopathy could be masked. We experienced a case of forty-one year old man suffered from gait disturbance and decreased proprioception. Initially surgeons concluded his weakness resulted from myelopathy by C5-6 centrally herniated disk based on MRI and surgical decompression was performed. Gait disturbance slightly improved but decreased proprioception did not improve. Vitamin B12 deficiency was found and high signal intensity lesions were found in dorsal and lateral spinal column with review of pre-op MRI. After administration with vitamin B12 supplements, weakness and sensation of proprioception improved and follow-up MRI showed decreased signal intensity. We concluded the cause of his symptoms was combination of compressive myelopathy and vitamin B12 deficient myelopathy.
