    Detection thresholds for Semmes-Weinstein monofilaments (SW tester), a 5-Hz rectangular electric stimulus and a warming stimulus were measured in the normal lower lip and chin area of 242 subjects (87 males, 155 females). Differences in terms of the stimulated region, gender and age were examined and the coefficients of variance (CVs) of the thresholds of subjects for the various stimuli were examined to determine the reliability of the measurements.
    The lower lip was more sensitive than the chin area to all stimuli. The threshold for the automatically increased warming stimulus including reaction time was higher than that for a specific warming stimulus excluding the reaction time. The thresholds of the lower lip and chin area for all stimuli tended to be higher for elderly subjects than younger ones, except for the thermal threshold of the lower lip; the thermal threshold of the lower lip was found to be independent of age. The thresholds for the warming stimulus of the lower lip and chin area were independent of gender, whereas the thresholds for the SW tester of the lower lip and chin area appeared to be related to gender in subjects aged in their 30s to 60s. Moreover, the thresholds for the 5-Hz rectangular electric stimulus appeared to be related to gender in subjects in their teens to 40s. The CVs of the thresholds to the 5-Hz rectangular electric stimulus and warming stimulus were lower than those to the SW tester.

    The 2005 CPR guidelines emphasize the importance of chest compression. The most recent guidelines recommend starting chest compression before rescue breath. However, the effect of chest compression in a dental chair is unknown.
    We investigated the efficacy of chest compression in a dental chair. The 26 study participants were experienced medical staff of the Nara Medical University Hospital. Chest compression was performed on a resuscitation manikin placed on a hospital bed, floor or dental chair with/without a CPR backboard (with a metronome that beeped 100 times per minute). The average depth of chest compression was 40.3 mm on the floor, 33.8 mm on the bed, and 32.3 mm in the dental chair. A significant reduction was observed on the bed (p < 0.01) and in the dental chair (p < 0.01) compared with that on the floor. The average depth of chest compression significantly increased to 37.9 mm on the bed (p < 0.01) and 34.6 mm in the dental chair (p < 0.05) with a CPR backboard. However, chest compression in the dental chair with a CPR board was not effective for cardiopulmonary resuscitation. Therefore, we placed a side chair under the dental chair and performed chest compression again. As a result, the depth of chest compression was significantly deeper when using the side chair than CPR board, showing the possibility of good chest compression pressure in the dental chair. However, the evidence supporting CPR in the dental chair is exiguous, so we must look more carefully into this point.

    A case of pulmonary metastasis and local recurrence from adenoid cystic carcinoma of the submandibular gland over 20 years after the first operation is presented. The patient, an 88-year-old woman, was referred to our department in 2009 because of pain in the submandibular region. At the initial visit, a swelling measuring 20 mm in diameter was found in the right inferior border of the mandible. The patient complained of spontaneous pain and slight pressure pain. The mass was elastic hard and immobile on palpation. CT imaging showed the submandibular mass was a solid lesion enhanced generally and the border was indistinct. Her past medical history revealed that she had undergone resection of a submandibular tumor in 1986 (histological examination: adenoid cystic carcinoma) and a pulmonary tumor in 2007 (histological examination: adenoid cystic carcinoma) in another hospital. Recurrence of the submandibular gland tumor was suspected from the clinical course, and so the submandibular tumor was excised. The pathological diagnosis of the submandibular tumor was adenoid cystic carcinoma, and it was regarded as a recurrence. The postoperative course was uneventful and follow-up by our department has found no recurrence.

    Lens luxation occurs when the lens is displaced from its normal position mostly due to blunt trauma. Precise diagnosis at the initial stage is needed because a luxated lens can cause visual disorders.
    We present a case report of complete lens luxation following facial trauma. A 68-year-old woman suffered severe lacerations to the face, and fracture of the zygoma and femur in a traffic accident and was transferred to our Emergency Unit. CT scan and ultrasonography revealed displacement of the left lens to the ocular fundus. She was immediately referred for ophthalmologic consultation and was diagnosed as complete lens luxation. The luxated lens showed no urgent symptoms and was treated conservatively, although the fractures were surgically reduced. Visual acuity was restored to 0.6 by wearing a contact lens later.
    Maxillofacial injuries, especially midface fractures, are frequently complicated by ocular injuries which can cause serious visual dysfunction. All traumas to the face, particularly fractures of the middle third of the facial skeleton, require ophthalmologic consultation and careful ocular examination.
