The aim of this study was to identify correlations between sleep bruxism (SB) and temporomandibular disorders (TMD) as diagnosed by means of the research diagnostic criteria for temporomandibular disorders (RDC/TMD). Sleep bruxism was diagnosed on the basis of I) validated questionnaires, II) clinical symptoms, and III) electromyographic/electrocardiographic data. A total of 110 subjects were included in the study. Fifty-eight patients were identified as bruxers and 52 as nonbruxers. A psychosocial assessment was also performed. An RDC/TMD group-I diagnosis (myofascial pain) was made for 10 out of 58 bruxers, whereas none of the nonbruxers received a diagnosis of this type. No significant differences were found between bruxers and nonbruxers with regard to RDC/TMD group-II (disc displacement) and group-III (arthralgia, arthritis, arthrosis) diagnoses. Somatization was significantly more common among bruxers than nonbruxers. Multivariate logistic regression analysis revealed that somatization was the only factor significantly correlated with the diagnosis of myofascial pain. The results of this study indicate a correlation between myofascial pain, as diagnosed using the RDC/TMD, and somatization. It seems that somatization is a stronger predictor of an RDC/TMD diagnosis of myofascial pain than sleep bruxism is.

Introduction. Cardiovascular (CV) diseases and bone fractures due to osteoporosis are the leading causes of death in the elderly. Objective. The aim of this study was to demonstrate a correlation between the overall risk for CV events, and low bone density in postmenopausal women, and its impact on the incidence of serious CV events. Methods. Our prospective study involved 300 postmenopausal women. All the examinees were divided into three groups based on their measured bone density: Group I - 84 examinees with osteoporosis; Group II - 115 examinees with osteopenia; and Group III - 101 examinees with normal bone density. In all examinees the overall ten-year risk for a fatal CV event was calculated using the SCORE system tables. Results. After a 36-month follow-up, CV events occurred in 19 (6.3%) examinees. Significant differences in the incidence of CV events were demonstrated between the patients with osteoporosis, osteopenia, and normal bone density (?2=28.7; p<0.001), as well as between those with a high and low CV risk (?2=22.6; p<0.001). Multivariate logistic regression analysis showed that smoking (OR: 2.23; 95% CI: 1.02 to 6.19; p=0.035), and increase of overall CV score (OR: 1.36; 95% CI: 1.17 to 1.58; p<0.001) are associated with increased CV event risk, while the increase of T score value is associated with decreased risk of CV event (OR: 0.42; 95% CI: 0.25 to 0.73; p=0.002). Conclusion. Measurement of bone density with a standard assessment of the total CV risk could be useful for selecting women who need intensive prevention and treatment of atherosclerosis.

Abstract Background: The clinical and CT manifestations of COVID-19 pneumonia and non-COVID-19 pneumonia in the same period have not been compared in detail. The purpose of this study is to analyze the clinical and CT manifestations of COVID-19 pneumonia and perform a comparison of those isolated patients for presumed COVID-19 infection and of non-COVID-19 pneumonia in the same period.Methods: 173 patients with pneumonia from January 1, 2020 to March 20, 2020 were retrospectively enrolled and classified into three groups: patients with COVID-19 pneumonia (Group I, N=4), patients in hospital-isolation for presumed COVID-19 pneumonia (Group Ⅱ, N=5), and patients with non-COVID-19 pneumonia (Group III, N=163). Clinical symptoms, laboratory test results and CT imaging features were compared among three groups.Results: Fever and cough were the most common clinical symptoms in the three groups. 30/163 (18.4%) patients were asymptomatic in Group III. Leukopenia, lymphocytopenia, and elevated C-reactive protein was identified in 1 (25%), 1 (25%), and 1 (25%) patient in Group I; 1 (20%), 1 (20%), and 2 (40%) patients in Group II; 10/157 (6.4%), 33/157(21.0%), and 94/136 (69.1%) patients in Group III. Demarcated GGO/mixed GGO, ill-defined GGO/mixed GGO, consolidation, centrilobular nodule, tree-in bud opacity, bilateral involvement, peripheral distribution, posterior part/lower lobe predilection was observed in 3/4 (75%), 2/4 (50%), 4/4 (100%), 2/4 (50%), 0, 3/4 (75%), 3/4 (75%), and 2/4 (50%) patients, respectively in Group I; 1/5 (20%), 5/5 (100%), 4/5 (80%), 4/5 (80%), 3/5 (60%), 4/5 (80%), 2/5 (40%), and 3/5 (60%) patients in Group Ⅱ; 1/163 (0.6%), 87/163 (54.3%), 115/163 (70.6%), 117/163 (71.8%), 95/163 (58.3%), 52/163 (31.9%), 9/163 (5.5%), and 9/163 (5.5%) patients in Group III, respectively.Conclusions: Demarcated GGO and consolidation prefer the diagnosis of COVID-19 pneumonia, whereas ill-defined GGO and consolidation, centrilobular nodule surrounded by GGO, and tree-in-bud opacity are preferred for non-COVID-19 pneumonia. chest CT has potential in early identification of COVID-19 and implementation of isolation for appropriate case.

Oral Behavior

Despite the extensive use of oral splints in the treatment of temporomandibular disorders (TMD) and bruxism, their mechanisms of action remain controversial. Various hypotheses have been proposed to explain their apparent efficacy (i.e., true therapeutic value), including the repositioning of the condyle and/or the articular disc, reduction in the electromyographic activity of the masticatory muscles, modification of the patient's "harmful" oral behavior, and changes in the patient's occlusion. Following a comprehensive review of the literature, it is concluded that any of these theories is either poor or inconsistent, while the issue of true efficacy for oral splints remains unsettled. However, the results of a controlled clinical trial lend support to the effectiveness (i.e., the patient's appreciation of the positive changes which are perceived to have occurred during the trial) of the stabilizing splint in the control of myofascial pain. In light of the data supporting their effectiveness but not their efficacy, oral splints should be used as an adjunct for pain management rather than a definitive treatment. For sleep bruxism, it is prudent to limit their use as a habit management aid and to prevent/limit dental damage potentially induced by the disorder. Future research should study the natural history and etiologies of TMD and bruxism, so that specific treatments for these disorders can be developed.

✓ In the search for a new synthetic substitute for the dura mater, the authors conducted a research study using 32 mongrel dogs divided into three groups. Group I animals (21 dogs) underwent a right-sided parietooccipital craniotomy and substitution of two 1-cm pieces of dura mater by two different grafts: one piece of biosynthetic cellulose (50 µ thick) and one fragment of temporal fascia. The animals were observed for 30, 90, or 180 days. Group II animals (five dogs) underwent a somewhat larger craniotomy, removal of a 2-cm piece of dura mater, and lesioning of the cortex made by a thin sharp forceps, which caused bleeding that was controlled by application of a thin film of cellulose (10 µ thick). Duraplasty was performed using a 50-µ-thick cellulose membrane to complete the procedure and the animals were observed over a period of 270 days. Group III animals (six dogs) underwent smaller (1-cm diameter) bilateral parietal craniectomy, which included additional covering of the dura on the left side with 50-µ-thick cellulose and a suture of temporalis muscle. This group was observed for 40, 60, 80, or 120 days. Transient mild clinical symptoms were observed during the early postoperative period. At autopsy, macroscopic examination demonstrated good acceptance of the grafts with few and moderate extradural fibrosis, which caused adherence of the implants to the bone fragment. No adherence to the cortex was observed. Microscopic examination demonstrated absence of graft adherence to the cortical surface even when the cortex was injured. The cellulose was enveloped by two layers of connective tissue, the external layer being thicker than the internal one. Cellulose fibers increased in thickness over time until 30 days and then decreased in thickness until 270 days. This decrease in thickness between 30 to 270 days was statistically significant (p < 0.05). The physical properties of biosynthetic cellulose and the low cellular reaction to its implantation qualify this material as a dural substitute. Additional long-term studies must be undertaken to complete this report.

ABSTRACTObjective: The present comparative study was aimed to determine the effectiveness of Th US and TENS in the management of myofascial pain in TMD patients. Materials and Methods: The present randomized comparative study was on 90 patients who were further assigned in three different groups each having 30 patients; Group I was healthy control patients, Group II was receiving Th US therapy, and Group III was receiving TENS therapy. All the 90 patients were further evaluated for maximum inter incisor subjective evaluation regarding muscle pain, impediment to daily life, massage impression on visual analog scale (VAS) scale, and intensity and duration used in Th US massage. Results: The masseter muscle thickness in control group was 12.00 (standard deviation [SD] ±1.1) mm when compared with TMD patient of 13.00 (SD ± 1.1) mm before treatment. Statistical significant findings on VAS score of muscle pain, impediment to daily life, and massage impression were observed in Th US. After treatment, the anechoic areas disappeared or were reduced in Th US group by 95.6% and in TENS by 74.4%. Conclusion: Th US appeared to be subjectively better which was related to VAS score of massage impression, muscle pain, and impediment to daily life after treatment as well as sonographically related to existence of anechoic areas.

There is no conclusive evidence as to whether patients with testosterone deficiency (TD) who benefit from testosterone treatment (TRT) must continue the treatment for the rest of their lives. In some patients, the effect of TRT does not maintained after stopping TRT and, some patients show no significant TD symptoms, with normal testosterone levels after TRT cessation. Therefore, we investigated the predictive factors of response maintenance after TRT cessation. A total of 151 men with TD who responded to TRT were followed up for six months after TRT discontinuation. Ninety-two patients (Group I) failed to show response maintenance; 59 patients (Group II) had a maintained response. The groups did not differ in baseline characteristics or the type of TRT (oral, gel, short/long-acting injectables). However, TRT duration was significantly longer (10.7 vs. 5.2 months), and peak total testosterone (TT) level was significantly higher (713.7 vs. 546.1 ng/dL), in Group II than in Group I. More patients regularly exercised in Group II than in Group I (45.8% vs. 9.8%, p < 0.001). A multivariate logistic regression analysis revealed that exercise (B = 2.325, odds ratio = 10.231, p < 0.001) and TRT duration (B = 0.153, Exp(B) = 1.166, p < 0.001) were independent predictive factors of response maintenance. In men with TD who respond to TRT, longer treatment periods can improve the response durability after TRT cessation, regardless of the type of TRT. Additionally, regular exercise can increase the probability of maintaining the response after TRT cessation.

Objective. To investigate serum levels of free β-HCG, progesterone, and ischemia-modified albumin (IMA) and their combined use in the prediction of first trimester abortions. Methods. A total of 156 pregnant women between 5 and 13 weeks of gestational age were included in this study. At admission, serum levels of free β-HCG, progesterone, and IMA were noted and all cases were divided into two groups; Group I (n=77) resulted in abortion including missed abortion, incomplete/complete abortion, and inevitable abortion whereas Group II (n=79) included normal pregnancies. Results. Compared to Group II, the significantly decreased value of free β-HCG progesterone and significantly increased value of IMA were found in Group I (P<0.01, P<0.01, P<0.01, resp.). When combining all three parameters, sensitivity 75%, specificity 99%, PPV 98%, and NPV 76% were obtained. The multivariate logistic regression analysis revealed the free β-HCG, progesterone, and IMA independent factors in the prediction of abortions. Conclusions. The combined use of free β-HCG, progesterone, and IMA levels can be useful in the prediction of first trimester spontaneous abortions.

Abstract OBJECTIVE To determine whether there are magnetic resonance imaging (MRI) characteristics of fatty fila that are correlated with neurological deficits, especially in the presence of a normal-level conus medullaris. METHODS Lumbosacral MRI scans were reviewed for patients with fatty fila who were treated at Duke University Medical Center during a 5-year period. The patients were divided into three groups. Group I patients (n = 5) had fatty fila that were incidentally detected during evaluations for metastases or infections. Group II patients (n = 16) exhibited isolated low back pain but were in neurologically intact condition. Group III patients (n = 15) exhibited neurological impairments consistent with distal spinal cord dysfunction. Several characteristics were measured on the MRI scans, including the location of the conus medullaris, the filum thickness, and the distance of fat from the conus. These results were assessed for statistically significant correlation with the presence of clinical symptoms. RESULTS The majority of patients in all three groups demonstrated the normal conus position (L2 or above) and thickened fila. The distance of fat from the conus was the only parameter that demonstrated a statistically significant difference among the groups. CONCLUSION The following findings were noted: 1) patients were likely to exhibit neurological deficits at a younger age (&lt;22 yr in Group III versus 47 yr in Groups I and II); 2) a conus level below L2 was associated with neurological deficits (Group III); 3) filum thickness was not correlated with clinical presentation; 4) fat in the filum within 13 mm of the conus medullaris was most predictive of neurological deficits (Group III).

OBJETIVE: To evaluate a sample of patients with persistent facial pain unresponsive to prior treatments. METHODS: Hospital records of 26 patients with persistent facial pain were reviewed (20 female and 6 male). RESULTS: Patients were classified into three groups according to their presenting symptoms: a)Group I, eight patients (30.7%) with severe, diffuse pain at the face, teeth or head; b)Group II, eight patients (30.7%) with chronic non-myofascial pain and; c)Group III, ten patients with chronic myofascial pain (38.4%). We find 11 different diagnoses among the 26 patients: pulpitis(7), leukemia(1), oropharyngeal tumor(1), atypical odontalgia(1), Eagle's syndrome(1), trigeminal neuralgia(4), continuous neuralgia(1), temporomandibular disorders (9), fibromyalgia (2), tension-type headache(1), conversion hysteria(2). After the treatment program all patients had a six-month follow-up period with pain relief, except the patient with tumor. CONCLUSION: The wide variability of orofacial pain diagnosis (benign to life-threatening diseases) indicates the necessity to reevaluate patients presenting recurrent pain that is refractory to the usual treatments.

Temporomandibular disorder is a collective term for a group of musculoskeletal and neuromuscular conditions. Patients will complain of pain in the TMJ region and the fatigue of the Cranio cervico facial muscles. The aim of the study was to assess the prevalence of TMD in patients visiting a private dental college. This was a retrospective study. Samples were collected from June 2019 to March 2020. The sample size was 55 patients. Data of Temporomandibular disorders were collected. Excel tabulation was done. Chi-Square test was performed and results were obtained using SPSS software. Out of 55 patients, the prevalence of group I of RDC criteria was 34.5%, prevalence of group II of RDC criteria was 62% and the prevalence of group III of RDC criteria was 3.5%. From the present study, it can be concluded that the prevalence of TMD in patients visiting a private dental College was very less. Group II of our RDC criteria was found to be high, with a percentage of 62%.
