Objective: It has been reported that temporomandibular joint (TMJ) function after orthognathic surgery differs from normal patients. Dysfunction of the joints occurs often even in the general public, with an incidence in the range of 20%–25%. Population-based studies among adults report that approximately 10%–15% have symptoms of pain and 5% of them had a perceived need for treatment. To date, no studies have reported on the evaluation of TMJ function after orthognathic surgery through the use of four-dimensional jaw tracking. Design and setting: This study evaluated TMJ function using such a device and information from a TMJ questionnaire. Sixteen orthognathic surgery patients and 17 controls were included in this study. Four-dimensional jaw tracking information was obtained using the SiCAT JMT device. Clinical signs and jaw function were evaluated. Results: Within the limitations of the study, the following results were seen using the SICAT JMT+ jaw tracking device: (1) no significant differences were found in any of the millimetric measurements between the surgery patients and controls; (2) no significant difference was found in subjective reported symptoms of pain, clicking, crepitation, locking, stiffness, headaches and migraines between the groups; and (3)there was a significant difference in the popping of the joints for surgery and non-surgery groups. Conclusion: Jaw tracking did not detect significant differences in jaw function, but some clinical symptoms were present.

Abstract Objective: To test the null hypothesis that there are no differences between children and adults in maximum laterotrusion and maximum retrusion on the right and left sides. Materials and Methods: This population-based study included 81 randomly selected children between the ages of 6 and 10 years and 67 adults. Kinematic variables were measured with the ultrasonic JMA-System for registration. Results: The mean maximum laterotrusion of the children's group (10.6 ± 1.5 mm on the left, 11.0 ± 1.7 mm on the right) was significantly smaller than that of the adult group (11.7 ± 2.0 mm on the left, 12.2 ± 1.7 mm on the right). The maximum laterotrusion of the children's group corresponded to about 90% on the left and right sides of that of the adult group. The mean maximum retrusion of the children's group was significantly bigger than that of the adult group. There, the adult values corresponded to 66.7% on the left and 50% on the right side of the children's values. No significant difference in maximum laterotrusion and retrusion was noted on the right and left sides, and no significant differences according to gender specificities were observed in either group. Conclusions: The hypothesis is rejected. In development of the temporomandibular joint, maximum laterotrusion on the right and left sides increases significantly with age, and maximum retrusion decreases significantly with age.

Objective(s):The objective of this study was to determine the frequency of “subluxation” and presence of clinical signs of Temporomandibular Joint Disorder (TMD) in asymptomatic individuals and its distribution according to age and sex.Materials and Methods:The material investigated comprised of 200 asymptomatic subjects with 400 joints. The subjects were divided into two groups of 18-25 years and 50-60 years of age consisting of equal number of males and females. Clinical examination involved measurement of maximal inter-incisal distance, joint sounds and deviation. For radiological examination, Temporomandibular Joint (TMJ) open mouth close mouth view option (TMJ1/2) was used on a Digital Panoramic Machine. All the radiographs were traced to assess subluxation and anterior translation of the condyle. The statistical analysis was carried out using Statistical Package for Social Sciences (SPSSInc., Chicago, IL, version 15.0 for Windows).Results:The prevalence of the signs of TMDs in the asymptomatic population was found to be very high and more predominant in females as compared to males. Furthermore, the older age group had comparatively less signs of TMDs. It was of interest that the subjects presenting with clinical signs of TMD were significantly less as compared to the subjects presenting with subluxation. The value of anterior translation was found to be more in females in the younger age group as compared to the males. Similarly, it was more in males as compared to females in older age group. But the mean anterior translation difference in females in 18-25 years and 50-60 years showed a statistically significant difference withP-value 0.017.Conclusion:Subluxation is a very common feature found in almost all the subjects in this study with a high prevalence. Hence, we may assume that the increased incidence of TMDs could be a direct result of the phenomena of subluxation. The decrease in mandibular length could be the cause of decreased mouth opening and increased subluxation.

Manifest pre-excitation on the surface electrocardiogram (ECG) with a short PR interval and delta wave occurs in a very small percentage of the population based on epidemiological data. For the vast majority, this ECG finding will have no clinical manifestation and over time the ECG manifestation of pre-excitation may even go away. A small minority of individuals, however, develop clinical signs related to ventricular pre-excitation, most notably atrioventricular reentrant (reciprocating) tachycardia. This non-life-threatening arrhythmia is associated with clinical symptoms of palpitations, dyspnoea, and presyncope. Those with ventricular pre-excitation are at increased risk for atrial fibrillation. Multiple invasive electrophysiological and longitudinal studies have shown that those with atrial fibrillation and robust conduction down the atrioventricular accessory pathway are at an increased risk of sudden cardiac death from ventricular fibrillation. This chapter reviews the available and recommended strategies for assessing the patient with asymptomatic pre-excitation.

Abstract Background The purpose of this retrospective study was to evaluate the postoperative change in the position and stability of the mandibular condyle after bilateral sagittal split ramus osteotomy (BSSRO) and BSSRO with distal segmental ostectomy (DSO) in patients with facial asymmetry using 3D computed tomography. Methods The condyles of the patient diagnosed with facial asymmetry were divided into the deviated side (DS) and the non-deviated side (NDS). Group I, which was treated with BSSRO only, and Group II, which additionally received DSO along with BSSRO, were superimposed on the condyle using the pre-and postoperative 3D CT. The amount of condylar change in anteroposterior displacement, mediolateral displacement, and rotation was measured. The clinical symptoms of temporomandibular joint were also evaluated before and after surgery for each patient. Results Between Groups I and II, there was no statistically significant difference in the anteroposterior condylar position on both DS and NDS. And also, there was no statistical difference between the two groups in the mediolateral change on DS but, statistically significant difference on NDS. The change in the rotation of the condyle was observed to rotate inward from both condylar heads of Groups I and II, and a statistically significant difference was observed between the two groups on both DS and NDS. Moreover, no difference in clinical temporomandibular joint symptoms was observed after surgery in each DS and NDS condyle of the two groups. Conclusions As a result of analyzing the condylar position change of the group treated with BSSRO alone and the group treated with BSSRO and DSO in patients with facial asymmetry, there were statistically significant differences in the mediolateral displacement of NDS and the condyle rotation of NDS and DS. However, the anteroposterior condylar position did not show any difference in the bilateral condyles. In addition, since worsening clinical symptoms of bilateral temporomandibular joint were not observed before and after surgery in both groups, it is concluded that it is not necessary to accompany DSO in patients with facial asymmetry (minimum 3 mm, maximum 7 mm).

Background:Autoinflammatory diseases (AIDs) are a group of rare, genetically determined diseases characterized by a periodic events of inflammation, fever, and clinical symptoms that mimic rheumatic pathology. Laboratory serological markers of AIDs are C reactive protein (CRP) and serum amyloid A (SAA) protein.Objectives:We investigated whether SAA1 gene polymorphism -13T/C (rs12218) may affect the susceptibility to pediatric FMF and CAPS patients (pts). We also evaluate whether this polymorphism can affect CRP and SAA protein levels.Methods:26 FMF pts - 8 boys, 18 girls; age - M(SD) 7.37(5.32) years and 24 CAPS pts - 12 girls, 12 boys; age – 4.76(5.83) years, and 95 healthy individuals (controls) were included in this study. The diagnosis of FMF was based on Turkish paediatric criteria for the diagnosis of familial Mediterranean fever [1] and was confirmed by the detection of pathogenic mutations of the MEFV gene in the homozygous or compound-heterozygous states. The diagnose of CAPS was made on the basis of characteristic clinical signs and was confirmed by the detection of a pathogenic mutation in the NLRP3 gene. SAA1 gene polymorphism -13T/C was genotyped using allele-specific RT-PCR assay. SAA protein concentration was measured using nephelometry in FMF and CAPS pts.Results:Table 1 shows the genotypic and allelic frequencies of SSA1 gene in FMF, CAPS and controls. There were no significant differences between FMF pts and controls in the genotypic and allelic distributions of -13T/C gene polymorphism. The frequency of -13C allele was significantly higher in CAPS pts compared with controls (OR=2.03 [CI 1.02-4.03], p=0.03). Moreover, a statistically significant difference was revealed in the genotypic and allelic distributions between FMF and CAPS pts groups (p=0.047 and p=0.02 respectively). The CRP levels did not correlate with SAA1 - 13T/C polymorphism. The SAA protein concentration was associated with SAA1 gene polymorphism in FMF pts (p=0.036).Table 1.The distribution of genotypes and alleles of SAA1 gene polymorphism -13T/C in FMF, CAPS and control groups.Genotypes/AllelesFMFn=26 (%)CAPSn=24 (%)Controlsn=95 (%)TT12 (46,2)4 (16,7)39 (41,1)TC12 (46,2)14 (58,3)42 (44,2)CC2 (7,7)6 (25,0)14 (14,7)P (pts vs controls)>0,05>0,08T24 (63,2)21 (50,0)80 (61,5)C14 (36,8)21 (50,0)50 (38,5)P (pts vs controls)>0,050.03Conclusion:Our preliminary study in small groups of pediatric FMF and CAPS pts revealed that SAA1 gene polymorphism -13T/C (rs12218) is associated with susceptibility to CAPS, but not FMF. The influence of this polymorphism on SAA protein levels in FMF pts was also shown. Further investigations are required to clarify the role of SAA1 gene polymorphism -13T/C in susceptibility to FMF and CAPS in large studies in different ethnic and population groups.References:[1]Yalcinkaya F, Ozen S, Ozcakar ZB, et al.

Perceived Need For Treatment

Objectives: Prevalence estimates of mental disorders were designed to provide an indirect estimate of the need for mental health services in the community. However, recent studies have demonstrated that meeting criteria for a DSM-based disorder does not necessarily equate with need for treatment. The current investigation examined the relation between self-perceived need for mental health treatment and DSM diagnosis, with respect to quality of life (QoL) and suicidal ideation. Methods: Data came from an Ontario population-based sample of 8116 residents (aged 15 to 64 years). The University of Michigan Composite International Diagnostic Interview was used to diagnose mood, anxiety, substance use, and bulimia disorder according to DSM-III-R criteria. We categorized past-year help seeking for emotional symptoms and (or) perceiving a need for treatment without seeking care as self-perceived need for treatment. We used a range of variables to measure QoL: self-perception of mental health status, a validated instrument that measured well-being, and restriction of activities (current, past 30 days, and long-term). Results: Independent of subjects' meeting criteria for a DSM-III-R diagnosis, self-perceived need for treatment was significantly associated with poor QoL (on all measures) and past-year suicidal ideation. Conclusions: Self-perceived need for mental health treatment, in addition to DSM diagnosis, may provide valuable information for estimating the number of people in the population who need mental health services. The relation between self-perceived need for treatment and objective measures of treatment need requires future study.

Abstract Background: Aseptic meningitis is not a common feature in Kawasaki disease (KD). However, it could cause difficulty in making correct and in-time diagnosis Methods: We retrospectively investigated patients of KD and bacterial meningitis (BM). Totally 38 KD patients and 126 BM patients were brought into this study. Clinical symptoms, signs and laboratory examinations were compared between the two groups, which included: duration of fever before lumbar puncture, conjunctiva injection, oral cavity change, rash, cervical lymphadenopathy and extremities change, vomiting, front fontanel bulging, neck stiffness, leukocytes, hemoglobin, platelets, C-reactive protein, cerebrospinal fluid examinations, liver function and urinalysis. Results: In clinical signs, vomit and neck stiffness were more prevalent in BM. KD patients showed higher blood leukocyte (p<0.001) and C-reactive protein (p<0.001) in the early febrile stage. Glucose in cerebrospinal fluid of BM patients was significantly lower than KD patients (p=0.003). In ROC curve, the optimal cutoff value of CSF glucose was 2.945mmol/L with the sensitivity of 84.2% and specificity of 71.4%. Pyuria was more prevalent in KD patients (p<0.001). There was no significant difference in front fontanel bulging, hemoglobin, platelet, alanine transaminase, aspartate transaminase, albumin, cerebrospinal fluid leukocytes, cerebrospinal fluid protein and cerebrospinal fluid lactate dehydrogenase. Conclusions ： Full investigation of clinical manifestation and laboratory tests is necessary to distinguish KD with aseptic meningitis and BM. In CSF study, glucose level is more efficient than other items to distinguish these two diseases. Decreased CSF glucose is possibly an indicator of BM rather than KD.

Abstract Objectives: To describe a facilitated procedure of colorectal filling contrast ultrasonography (CFCUS) and investigate its potential role in the assessment of paediatric juvenile polyps. Methods: The general information, clinical symptoms, ultrasound image characteristics, and colonoscopy findings of 101 children with clinical signs of colorectal polyps admitted to our hospital between May 2018 and May 2021 were retrospectively reviewed. All children underwent conventional transabdominal ultrasonography (CTUS), and CFCUS before colonoscopy, and the latter served as the gold standard. Chi-squared tests and Mann-Whitney U tests were used for the statistical analysis. Results: Forty-five children with fifty-two colorectal polyps were diagnosed by colonoscopy. Ten polyps had false-negative results on CTUS, six of which were detected by CFCUS. The sensitivity, specificity, positive predictive value, and negative predictive value of CFCUS vs CTUS was 92.3% vs 80.7%, 100% vs 100%, 100% vs 100%, 93.3% vs 84.8%, respectively. The maximum diameter of polyps (mean ± standard deviation) missed by CTUS was significantly smaller than that detected by CTUS (7.50±2.12 mm [range 4–12 mm] vs. 19.62±7.89 mm [range 6–41 mm], P<0.0001). A significant difference was observed between CTUS and CFCUS. The difference between CTUS and CFCUS regarding the detection rate of polyps with a diameter < 1 cm (P=0.031). A statistical difference was observed in the detection rate of polyps (P=0.031), and pedicles (P<0.001) between CTUS and CFCUS. The Kappa values for the assessment of Yamada’s classification between CTUS and colonoscopy and CFCUS and colonoscopy were 0.51 and 0.84, respectively. Six colonic polyps were accompanied by a punctate hyperechoic area on the surface, which may be suggestive of a correlation with erosion and bleeding findings.Conclusion: CFCUS can increase the detection rate of polyps and pedicles, especially polyps with diameters <1 cm, and accurately evaluate Yamada’s classification, providing useful preoperative information for colonoscopy.
