Increased Bolus Volume Effect on Delayed Pharyngeal Swallowing Response in Post-stroke Oropharyngeal Dysphagia: A Pilot Study.

OBJECTIVE: To confirm a relationship between the pharyngeal response and bolus volume, and examine whether increasing the fluid bolus volume can improve penetration and aspiration for stroke dysphagic patients. METHODS: Ten stroke patients with a delayed pharyngeal response problem confirmed by a videofluoroscopic swallowing study (VFSS) were enrolled. Each subject completed two swallows each of 2 mL, 5 mL, and 10 mL of barium liquid thinned with water. The pharyngeal delay time (PDT) and penetration-aspiration scale (PAS) were measured and the changes among the different volumes were analyzed. RESULTS: PDTs were shortened significantly when 5 mL and 10 mL of thin barium were swallowed compared to 2 mL. However, there was no significant difference in PAS as the bolus volume increased. CONCLUSION: The increased fluid bolus volume reduced the pharyngeal delay time, but did not affect the penetration and aspiration status.

Intractable verrucous hyperplasia: a surgically corrected case.

Skin problems commonly occur after lower limb amputation. One such skin anomaly that develops on the residual limb is wart-like lesions of verrucous hyperplasia. The process is reversible if external compression is applied in combination with adequate control of bacterial infection and edema. Prosthetic adjustments usually help with this condition. We report an intractable verrucous hyperplasia in a 66-year-old female patient. She complained of a painful, oozing, verrucous papule at the amputation site. Despite management with typical treatment procedures, the lesion worsened; therefore, surgery was performed. Our case demonstrates that an intractable case is possible despite appropriate management and that sometimes surgical correction is necessary.

Usefulness of the computed tomography venography for evaluation of leg edema including deep vein thrombosis in rehabilitation patients.

OBJECTIVE: To investigate the usefulness of computed tomography venography (CTV) for evaluation of leg swelling, especially deep vein thrombosis (DVT), in rehabilitation patients. METHODS: A hundred twenty-three patients, who had performed CTV performed because of suspected DVT in our clinic, were enrolled. We performed chart reviews retrospectively and categorized CTV findings as follows: DVT distal to inguinal ligament and no compression lesion; DVT proximal to inguinal ligament and no compression lesion; DVT distal to inguinal ligament and anatomical variant (for example, May-Thurner syndrome); DVT due to compression of mass (cancer or cyst); DVT and other incidental abnormal finding; and no DVT and other possible causes of leg swelling. RESULTS: DVTs were found in 65 (53%) patients. DVTs were found at distal level (thigh or lower leg) to inguinal ligament in 47 patients. DVTs were found at proximal to inguinal ligament, usually undetectable with duplex ultrasonography, in 6 patients. DVTs caused by external compression, such as femoral vein and cancer mass, were found in 12 patients (10%), which are also not easily detected with duplex ultrasonography. Other various causes of leg edema without DVT were found in 22 (18%) patients. CONCLUSION: CTV can evaluate more extensively venous problems in the pelvis and abdomen and detect other possible causes of leg swelling. Therefore, CTV can be a useful tool not only for easy detection of DVT but also for evaluating differential diagnosis of leg edema in rehabilitation patients.

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.
