ABSTRACT
OBJECTIVE: To investigate whether the concomitant presence of anterior cervical osteophytes can influence the severity and outcome of patients with poststroke dysphagia. DESIGN: Retrospective case-control study. SETTING: Hospital. PARTICIPANTS: A total of 40 participants were identified (N=40). Patients with poststroke dysphagia with anterior cervical osteophytes (n=20) were identified and matched by age, sex, location, and laterality of the stroke lesion to a poststroke dysphagia control group with no anterior cervical osteophytes (n=20). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Videofluoroscopic swallowing study, Functional Oral Intake Scale (FOIS), and Penetration-Aspiration Scale results assessed within the first month of stroke were analyzed. The FOIS at 6 months was recorded, and severity of dysphagia was compared between the 2 groups. RESULTS: The case group had larger degrees of postswallow residues in the valleculae and pyriform sinuses (P=.020 and P<.001, respectively), with more patients showing postswallow aspiration (62.5%) than the control group (0%; P<.001), along with a higher risk of being on enteral nutrition feeding (odds ratio [OR]=13.933; 95% confidence interval [CI], 2.863-infinity) within the first month of stroke. At the 6-month follow-up, the case group had significantly lower mean FOIS scores (3.8±1.7) than the control group (6.1±1.3; P<.001), with an increased risk of having persistent dysphagia (OR=15.375; 95% CI, 3.195-infinity). CONCLUSIONS: The presence of anterior cervical osteophytes, which may cause mechanical obstruction and interfere with residue clearance at the valleculae and pyriform sinuses and result in more postswallow aspiration, may influence initial severity and outcome of poststroke dysphagia. The presence of anterior cervical osteophytes may be considered an important clinical condition that may affect poststroke dysphagia rehabilitation.

Brachial plexus neuritis is reportedly caused by various factors; however, it has not been described in association with Streptococcus agalactiae. This is a case report of a patient diagnosed with brachial plexus neuritis associated with pyogenic arthritis of the shoulder. A 57-year-old man visited the hospital complaining of sudden weakness and painful swelling of the left arm. The diagnosis was pyogenic arthritis of the left shoulder, and the patient was treated with open irrigation and debridement accompanied by intravenous antibiotic therapy. S. agalactiae was isolated from a wound culture, and an electrodiagnostic study showed brachial plexopathy involving the left upper and middle trunk. Nine weeks after onset, muscle strength improved in most of the affected muscles, and an electrodiagnostic study showed signs of reinnervation. In conclusion, S. agalactiae infection can lead to various complications including brachial plexus neuritis.
ABSTRACT
OBJECTIVE: The aim of this study was to determine the location of the motor points and the intramuscular branches of the wrist flexors in relation to bony landmarks. DESIGN: Sixteen limbs from eight adult cadavers were anatomically dissected. The motor branch points of the flexor carpi radialis and flexor carpi ulnaris muscles and the proximal limit points and the distal limit points in relation to a reference line connecting the medial epicondyle and the pisiform bone or one connecting the medial epicondyle and the base of the second metarcarpal bone were identified. RESULTS: For the flexor carpi radialis muscles, the motor branch points were located at a distance of 27% ± 6% of the reference line, whereas the proximal limit points and the distal limit points were located at a distance of 21% ± 5% and 37% ± 8% of the reference line. For the flexor carpi ulnaris muscles, the corresponding data were 32% ± 8%, 23% ± 6%, and 43% ± 9%. CONCLUSIONS: The results may assist in enhancing accuracy when localizing points for neuromuscular blockade of the wrist flexors. The optimal area for flexor carpi radialis muscle injection is at a quarter point and that for flexor carpi ulnaris muscle injection is at one-third point along each reference line from the medial epicondyle.
