Temporomandibular joint involvement in psoriatic arthritis: a prospective clinical and ultrasonographic study.

To evaluate the prevalence of temporomandibular disorders (TMD) in a monocentric cohort of patients affected by psoriatic arthritis (PsA), and to investigate the accuracy of temporomandibular joint (TMJ) ultrasound (US) compared with clinical evaluation and clinimetric composite index in assessing TMJ involvement. We conducted a prospective cohort study of patients diagnosed with PsA who underwent at least one TMJ US examination and maxillofacial surgeon's evaluation between 2018 and 2021. The rheumatology physician's interpretation of each TMJ US exam (presence/absence of TMD) was compared with psoriatic arthritis disease activity indexes and maxillofacial surgeon's clinical judgement (presence/absence of TMD signs and/or symptoms). 142 psoriatic arthritis patients were included. 111 patients were totally asymptomatic for TMD, but 58.5% of them already showed TMJ US changes; moreover, 103 patients passed the maxillofacial surgeon's examination in the absence of any relevant findings but again, of these, 55.3% already presented US signs of TMD. Univariate analysis of subgroups with and without TMJ synovitis and with and without active power Doppler signal showed a significant prevalence of peripheral enthesitic involvement in patients affected by TMD (95.7% vs. 4.3%, p=0.001; and 72.2% vs. 27.3%, p=0.007, respectively). Multivariate regression analysis confirmed the results (p=0.01 and p=0.013, respectively). Peripheral enthesitic involvement may represent a potential risk factor for the development of TMJ synovitis in PsA patients. Since TMD often develops asymptomatically, TMJ US may detect early signs of TMD, ensuring precocious and adequate management.

Not strong enough? Movements generated during clinical examination of sagittal and rotational laxity in a cadaver knee

ABSTRACT BACKGROUND: Injury to the anterior cruciate ligament (ACL) is associated with sagittal and rotational laxity, which is exacerbated by damage to the anterolateral capsuloligamentous structures, also known as the anterolateral ligament (ALL). The amount of laxity reported in biomechanical studies might be clinically insignificant during a surgeon's examination, possibly influencing clinical judgement. We aimed to measure whether the motion generated by clinicians in a cadaver model after the ACL and ALL were transected is clinically significant METHODS: A group of orthopaedic surgeons and trainees examined a cadaver knee for sagittal and rotational laxity at 30° and 90° with intact ligaments, after the ACL was transected, and after the ACL and ALL were transected. The examiners were blinded to the dissection process. Rotational and sagittal movements during these examinations were recorded by a computer-assisted surgery (CAS) system RESULTS: Twenty-four orthopaedic surgeons took part in the study. The median sagittal plane motion captured by CAS at 30° flexion was 7 mm (IQR 2 mm, p-value 0.32) in the intact knee, 9 mm (IQR 1 mm, p-value 0.34) after the ACL was cut and 9 mm (IQR 3 mm, p-value 0.63) after ACL and ALL were cut. The median arc of rotational motion at 30° was 19° (IQR 7°, p-value 0.12) in the intact knee, 24° (IQR 5°, p-value 0.56) after the ACL was cut, and 22° (IQR 6°, p-value 0.8) after the ACL and ALL were cut. None of the differences in these movements was significant CONCLUSION: The surgeons could not generate significant differences in sagittal or rotational motion in a cadaver model, which could be objectively detected by CAS, when examining the intact knee, ACL deficient (only), or combined ACL and ALL deficient knee. This challenges the utility of known clinical tests and calls for improved objective laxity assessment tools to provide input in clinical decision-making and measure outcomes of these injuries Level of evidence: Level 5 Keywords: knee, anterolateral ligament, anterior drawer's test, pivot shift, rotatory instability, anterior cruciate ligament, iliotibial band, Kaplan fibres

Assessment of Septoplasty Effectiveness using Acoustic Rhinometry and Rhinomanometry.

Septal deviation is the chief cause of chronic nasal obstruction. In order to treat such cases, nasal septoplasty surgery is usually performed based on patient complaints and a surgeon's examination, both of which are subjective. This study aims at using the objective parameters of acoustic rhinometry and rhinomanometry to evaluate the effectiveness of septoplasty surgery. A prospective study was performed in 30 candidate patients for septoplasty surgery. Acoustic rhinometry and rhinomanometry tests were performed on all patients both before and 3 months after the operation. The symptom recovery rate was recorded according to the patient's statements and anterior rhinoscopic examinations 3 months after surgery. Data were analyzed using a t-test and chi-square tests in a SPSS package. A total of 26 of 30 patients returned for a post-procedure follow-up examination after 3 months. Patients were aged from 18 to 32 years (average, 25 years). In total 69.2% (18 patients) were satisfied with the results of the procedure. In addition, rhinomanometry resulted in a decrease in general nasal resistance if patients used decongestants (P=0.03). However, the decrease was not significant before the use of decongestants (P=0.12). Furthermore, according to the results from acoustic rhinomanometry, there was an increase in the nasal cross-sectional area on both the narrow and wide sides after the operation (P<0.05), although this increase was not so notable in the narrower side after using decongestants. There was, however, no significant relationship between the results from the objective tests and the patient's symptoms or clinical examinations (P>0.05). The findings of this study show that although the objective tests confirm an improvement in general nasal resistance and an increase in the nasal cross-sectional area after surgery, no unambiguous relationship between the patient's symptoms and the clinical examinations is observed. Therefore, such objective tests do not prove to be sufficient diagnostic criteria for the effectiveness of septoplasty.

Die präoperative Dünnschicht-Computertomografie im Management der Lungenmetastasenchirurgie

Inspection and palpation of the ventilated and exhausted lung reflect the guideline-compliant surgery of pulmonary metastases. Because a huge number of pulmonary nodules are missed on preoperative CT, metastases must be diagnosed by the surgeon's examination of the lung under exclusion of the video-assisted approach. The purpose of our study was to assess whether a special multislice (MS) spiral CT may close this diagnostic gap and change the management of pulmonary surgery. We performed a prospective study to address this question. Operative and histological results of 60 patients with pulmonary nodules (7/2002 and 12/2004) were compared with the preoperative predictions of MS-CT. In 81 operations, 166 pulmonary metastases were confirmed histologically. The MS-CT predicted 229 suspicious metastases; 38% could not be confirmed histologically. However, in 14% of surgically confirmed metastases the radiological correlate was absent. 44% of these metastases were <or=2 mm, 30%<or=4 mm, and 26%>4 mm; and were from the following primary entities: 48% hypernephroma, 30% sarcoma, 17% colorectal carcinoma and 4% breast cancer. The radiological prediction of 1 to 3 vs. 5 to 11 metastases implied 30% vs. 70% additional filiae, whereas radiologically non-described metastases were found in 12% of all operations. In contrast, the group with radiopaque material showed only 5% of metastases without a radiological correlate or 8% of non-described metastases. The overall sensitivity of MS-CT was 86%, whereas the group with radiopaque material had a sensitivity of 95%. The preoperative MS-CT does not resolve the problem of overlooked metastases and has no influence on the management of pulmonary surgery.

Postoperative pain and side effects after uvulopalatopharyngoplasty, laser-assisted uvulopalatoplasty, and radiofrequency tissue volume reduction in primary snoring.

We compared, in a prospective study, the side effects and the postoperative complications of three procedures commonly used for the treatment of primary snoring. Forty-nine patients underwent velopharyngeal surgery for primary snoring (17 for uvulopalatopharyngoplasty [UPPP]; 15 for laser-assisted uvulopalatoplasty [LAUP], and 17 for radiofrequency tissue volume reduction [RFTVR]). Preoperative full polysomnographic studies ruled out obstructive sleep apnea syndrome. Each patient's evaluation encompassed postoperative pharyngeal pain (as measured by a 5-point visual analogue scale) and use of narcotic drugs in the early postoperative period as well as a subjective evaluation of late postoperative complaints. A surgeon's examination was performed to report postoperative complications in the oropharynx. Postoperative pharyngeal pain was less important in the RFTVR group than in the UPPP and LAUP groups. Mean scores at days 3, 7, 16 were as follows: 4.2, 4.0, and 2.4, respectively, for UPPP; 4.6, 3.8, and 1.6 for LAUP; and 2.4, 2.0, and 0.7 for RFTVR. Mean duration of pain with a score greater than 2 was calculated as follows: UPPP, 21.3 days; LAUP, 15.1 days; and RFTVR, 6.1 days. Mean duration of narcotic drug use for the patients who needed this medication was 10.1 days for UPPP, 7.2 days for LAUP, and 1.3 for RFTVR. Postoperative side effects (trouble with smell and taste, pharyngeal dryness, globus sensation, voice change, and pharyngonasal reflux) were more present in the UPPP and LAUP groups than in the RFTVR group. Surgeon's assessment for postoperative complications reported more wound infection, dehiscence, and posterior pillar narrowing in the UPPP and LAUP groups than in the RFTVR group. RFTVR is a safer and less painful procedure than UPPP and LAUP for the treatment of primary snoring. Postoperative discomfort after LAUP and after UPPP appears to be very similar.
