RESUMO
Cephalic tetanus is defined as a combination of trismus and paralysis of one or more cranial nerves. Cranial nerves III, IV, VI, VII, and XII may be affected, but the facial nerve is most frequently implicated. A 64-year-old female visited hospital for left ptosis followed by facial palsy after a left forehead abrasion in a car accident. At nine days post injury, left ptosis developed, left facial palsy developed twelve days post injury, and at fifteen days post injury, trismus and dysphagia developed. The following day, there was progression of symptoms to generalized tetanus, such as dyspnea and generalized rigidity. Videofluoroscopic swallow study showed penetration and aspiration. We report a case of cephalic tetanus with ptosis, facial palsy, and dysphagia, which progressed to generalized tetanus.

Collet-Sicard syndrome is a rare condition characterized by the unilateral paralysis of the 9th through 12th cranial nerves. We describe a case of a 46-year-old man who presented with dysphagia after a falling down injury. Computed tomography demonstrated burst fracture of the atlas. Physical examination revealed decreased gag reflex on the left side, decreased laryngeal elevation, tongue deviation to the left side, and atrophy of the left trapezius muscle. Videofluoroscopic swallowing study (VFSS) revealed frequent aspirations of a massive amount of thick liquid and incomplete opening of the upper esophageal sphincter during the pharyngeal phase. We report a rare case of Collet-Sicard syndrome caused by Jefferson fracture.

OBJECTIVE: To delineate the clinical manifestation of myofascial pain syndrome (MPS) around the face, neck and shoulders in patients with cervical vertigo (CV) and to determine whether treatment of MPS can improve CV. METHOD: We evaluated 72 patients who were diagnosed with CV and 72 patients as controls who had MPS in the neck and shoulder without vertigo symptoms. Clinical evaluations for MPS were performed on all subjects, and vestibular function tests were also performed in patients with vertigo symptoms. Most patients and controls received treatments including trigger point injection, physical therapy or medication, and were then followed up. RESULTS: Seventy CV patients (97%) had MPS in the face, neck and shoulders. The distribution of trigger points in CV patients differed from that in controls, especially in the lateral neck muscles (odds ratio=0.361, p=0.019). The gender, age, symptom duration and number of trigger points were not different between CV patients and controls. 57 CV patients and 56 controls that had received treatments were followed up. Vertigo symptoms improved in 40 CV patients (70%) after treatment of MPS and pain symptoms improved in 77% of CV patients and 75% of controls after treatment. CONCLUSION: Most CV patients had myofascial pain syndrome and the distribution of trigger points differed from that in controls. Treatment for myofascial pain syndrome could improve vertigo symptoms in CV patients, but further study is required to delineate the relationship between MPS and CV.

Flash pulmonary edema typically exhibits sudden onset and resolves rapidly. It generally is associated with bilateral renal artery stenosis or unilateral stenosis in conjunction with a single functional kidney. We describe a patient who presented with flash pulmonary edema treated by percutaneous therapy with stent implantation. Our case is unique in that the flash pulmonary edema occurred in the setting of unilateral renal artery stenosis with bilateral functioning kidneys.

BACKGROUND AND OBJECTIVES: The aim of this study was to investigate the value of microbubble destruction using low-frequency ultrasound for enhancing gene delivery to skeletal muscles of laboratory animals. MATERIALS AND METHODS: Lac-Z gene was injected into 21 mouse anterior tibialis muscles. Seven muscles received the gene only, and seven each received either 20-kHz ultrasound exposure or ultrasound-PESDA (perfluorocarbon-exposed sonicated albumin) destruction, respectively, following the injection; the extent of Lac-Z expression was then compared. Luciferase gene was injected into the muscles (N=80). The muscles were divided into two groups according to the mixture; in the first group saline was used as the mixture solute, with PESDA used in the second group. The groups were subdivided into two groups, one receiv 10 seconds of ultrasound at the injection site after injection, and the other that received no further intervention. Luciferase activities were measured and compared. RESULTS: The proportions of Lac-Z stained cells were 0, 5.7+/-1.2 and 7.7+/-1.7%, respectively, showing a significant stepwise increase microbubble destruction (p<0.05). Luciferase activities were as follows: Luciferase only (Group 1, N=17), 5727+/-2178 RLU/mg; luciferase plus PESDA (Group 2, N=17), 1170+/-470.7 RLU/mg; luciferase plus ultrasound (Group 3, N=17), 16480+/-5239 RLU/mg; and luciferase plus PESDA destruction (Group 4, N=17), 49910+/-16500 RLU/mg. The activity in group 4 was significantly higher than in group 1 (p<0.01), showing an 8.7-fold increase in gene delivery due to microbubble destruction. CONCLUSION: Microbubble destruction using low-frequency ultrasound is an efficient method for increasing the efficacy of direct gene delivery to skeletal muscles.
