The efficacy of acupuncture and decompression splints in the treatment of temporomandibular joint pain-dysfunction syndrome.

OBJECTIVES: The goal of the present study was to evaluate the results of applying acupuncture or occlusal decompression splints in the treatment of patients diagnosed with the temporomandibular joint pain-dysfunction syndrome. DESIGN OF THE STUDY: We conducted a randomized clinical trial including 20 patients to whom the mentioned treatments were applied. Results were evaluated through an analogue pain scale, measurements of mouth opening and jaw lateral deviation in millimetres, and assessment of sensitivity to pressure on different points: preauricular, masseter muscle, temporal muscle and trapezius. Parameters were evaluated before and 30 days after the treatment. For standardized pressure, we used a pressure algometer. RESULTS: Patients treated with decompression splints showed reductions in subjective pain and pain upon pressure on temporal, masseter and trapezius muscles, as well as increased mouth opening after the treatment. Patients treated with acupuncture showed pain reduction in the short term and improvements in all of the evaluated para-meters (stronger pressure was required to produce pain; mouth opening was improved). CONCLUSION: Acupuncture was an effective complement and/or an acceptable alternative to decompression splints in the treatment of myofascial pain and temporomandibular joint pain-dysfunction syndrome.

Bone metabolism and clinical study of 44 patients with bisphosphonate-related osteonecrosis of the jaws.

UNLABELLED: Osteonecrosis of the jaws is a clinical entity described and linked to treatment with bisphosphonates in 2003. Its real incidence is unknown and it could increase due to the large number of patients treated with these drugs, and its cumulative effect on the bone. State of the art knowledge regarding its etiopathogeny, clinical course and suitable treatments is limited. OBJECTIVES: To study the clinical characteristics of 44 patients with bisphosphonate-related osteonecrosis of the jaws and the state of their bone mineral metabolism: bone remodeling state, prevalence of fractures, bone mineral density study, and assessment of the different treatment strategies. DESIGN OF THE STUDY: Observational. Information was gathered prospectively through interviews, clinical examinations, additional tests and review of medical records. RESULTS: We studied 16 men and 28 women with a mean age of 64.7 years. Breast cancer was the most frequent underlying disease. Zoledronate was used in 82% of the cases and in the non-oncology group of patients; alendronate was the most frequently used bisphosphonate. The mean duration of the zoledronate and alendronate treatments was 25 months and 88 months respectively. The lower jaw was the most frequent location, and previous exodontias-among the triggering factors known-were the most closely linked to its onset. We found considerable osteoblastic activity in patients suffering from neoplasia, with artifacts present in their bone densitometry and a high percentage of vertebral fractures. CONCLUSIONS: According to our results, osteonecrosis of the jaws affects elderly patients. We found a direct relationship between the duration of exposure and the accumulated dose. Other relevant factors are: Poor oral and dental health, corticoids, diabetes and teeth extractions. In essence, it is a clinical diagnosis. Prevention is the best strategy to handle this clinical entity.

Salivary enzymes and periodontal disease.

BACKGROUND: Host responses to periodontal disease include the production of different enzymes that are released by stromal, epithelial or inflammatory cells. There are important enzymes associated with cell injury and cell death like: aspartate and alanine aminotransferase (AST, ALT), lactate dehydrogenase (LDH), creatine kinase (CK), alkaline and acidic phosphatase (ALP, ACP), gama glutamyl transferase (GGT). Changes in enzymatic activity reflect metabolic changes in the gingiva and periodontium in inflammation. DESIGN OF STUDY: In this paper we have examined the activity of CK, LDH, AST, ALT, GGT, ALP and ACP in saliva from patients with periodontal disease before and after periodontal treatment (experimental group, 30 samples) and in saliva from healthy patients (control group--20 samples). Periodontal disease was determined based on clinical parameters (gingival index (GI), bleeding on probing (BOP), probing depth (PD)). Patients with periodontal disease were under conventional periodontal treatment. RESULTS: Obtained results were shown statistically significant increases of activity of CK, LDH, AST, ALT, GGT, ALP, ACP in saliva from patients with periodontal disease in relation to control group. There is positive correlation between the activity of examined salivary enzymes and value of the gingival index. After conventional periodontal therapy the activity of all salivary enzymes was significantly decreased. CONCLUSIONS: Based on these results, it can be assume that activity of these enzymes in saliva, as biochemical markers for periodontal tissue damage, may be useful in diagnosis, prognosis and evaluation of therapy effects in periodontal disease.

[Temporal paragangliomas. A 12-year experience]. / Paragangliomas temporales. Experiencia de 12 años.

OBJECTIVE: Our objective was to perform a retrospective analysis of patients with jugulotympanic paragangliomas. We present the results according to the surgical approach applied in each case. MATERIALS AND METHODS: This retrospective study presents the findings in 21 patients with jugulotympanic paragangliomas who were observed and treated in our department over a 12-year period (1999 to 2011). We performed a general otolaryngology exam, systemic evaluation and radiological exam. Surgical treatment was performed in 20 cases out of 21. In 1 case, treatment with stereotactic radiosurgery was carried out. RESULTS: The surgical approaches were: endaural, retroauricular transcanal, radical or modified mastoidectomy through facial recess and infratemporal fossa approach. Preoperative embolization was used in 12 cases. In all cases the diagnosis of paraganglioma was confirmed. The most frequent postoperative complications found were transitory palsy of the facial nerve, sensorineural hearing loss, imbalance, paralysis of the cranial nerves IX and XI and salivary fistula. No recurrences were found after 12 years of follow-up. One case of persistence was found in the case treated with radiosurgery. CONCLUSIONS: In our series surgery was found to be the elective therapy for patients with paraganglioma, with no recurrences after 12 years of follow-up. Preoperative embolization decreases surgery time and intraoperative bleeding. Stereotactic Radiotherapy cannot eliminate the tumour..

[Osteonecrosis of the jaw secondary to oral alendronate: Report of three cases]. / Osteonecrosis maxilar secundaria al uso de bisfosfonatos por vía oral: Exposición de tres casos clínicos relacionados con alendronato.

Osteonecrosis of the jaw associated to biphosphonate use is more common in cancer patients with bone metastases, that are using intravenous diphosphonates. When these drugs are used orally the risk of the complication is lower. We report 3 diabetic women aged 69, 76 and 82 years, receiving alendronate 70 mg every one week. The unveiling event was the extraction of several teeth without the use of antibiotics. All had bone pain, purulent discharge, loss of bone and halitosis. All improved five months after discontinuing alendronate.

Cartilage in the walls of odontogenic keratocyst.

There are seven published cases in world literature on cartilage in the walls of odontogenic keratocysts. Herein is presented one further case with keratin inclusions in the cystic wall, which also bears a cartilaginous component. X-rays, clinical images and pathohistological images are included.

Non-Hodgkin lymphomas of oral cavity.

Non-Hodgkin lymphomas (NHL) often show up in an extranodal pattern, especially in the head and neck. Intraoral locations are much less frequent, particularly when they are single. This, in turn, can lead to a prolonged diagnosis and even to inadequate treatment. Different patients with initial extranodal location of NHL which were not previously diagnosed and in which it was manifested only intraorally are presented in this paper. These cases are presented together with the additional examinations used for the early diagnosis and with the corresponding clinical pictures, as well as with the overview of other cases from the available literature.

Oral surgery in patients undergoing oral anticoagulant therapy.

UNLABELLED: There is an evident need for procedural protocol for oral surgery patients who undergo oral anticoagulant treatment (OAT) because of: 1) the possible severity of complications and 2) the growing demand for OAT, which in some cases may be as much as 8% of the oral surgery patients that are referred to the hospital from primary care centers. In this study, the authors define the parameters for creating a proto- col applicable to this group of patients. The conclusion is that it is not necessary to suspend OAT before surgery; rather, these procedures should be performed under multidisciplinary medical control. OBJECTIVE: The authors demonstrate that it is possible to perform oral surgery on OAT patients, without having to sus- pend treatment beforehand. STUDY DESIGN: A longitudinal study was performed in OAT patients that required some type of oral surgical procedures. After an INR control, the patient underwent surgery and afterwards the patient was given tranexamic acid as a mouth rinse. Postoperative hemorrhage was classified as slight when it lasted less than 5 minutes, moderate when it lasted longer than five minutes, and severe when it required blood transfusion. RESULTS: The study was performed over a 5-year period (1996-2000), by the maxillofacial surgery department. In that time period, 125 patients with OAT were treated; 90 of them were males and 35 were females. Tooth extraction was per- formed in 229 sessions and a total of 367 teeth were extracted, with an average of 1.6% per session. With regards to postoperative hemorrahage, it was slight in 210 cases (91.7%), moderate in 18 (7.9%) and severe only in one case (0.4%). All the variables were compared and no statistically significant differences were found. CONCLUSIONS: We believe that OAT should not be suspended before oral surgery, but it surgery should be performed under multidisciplinary control-especially in the case of the elderly (over 65) or with those patients that have other concomitant illnesses such as renal insufficiency or anemia or other medical treatments.
