Airway compartments volume and oxygen saturation changes after rapid maxillary expansion: A longitudinal correlation study.

Airway compartments volume and oxygen saturation changes after rapid maxillary expansion: A longitudinal correlation study. Angle Orthod. 2015 Nov;85(6):955-61 Authors: Fastuca R, Perinetti G, Zecca PA, Nucera R, Caprioglio A Abstract OBJECTIVE: To evaluate changes in airway volumes and respiratory performance in patients undergoing rapid maxillary expansion and determine whether any correlations exist between the morphological and respiratory functional modifications induced by rapid maxillary expansion and pretreatment airway stenosis. MATERIALS AND METHODS: Fifteen patients (11 females and 4 males; mean age, 7.5 ± 0.3 years) were enrolled in the study. Each patient underwent cone beam computed tomography and polysomnography examination before rapid maxillary expansion and after the removal of the maxillary expander 12 months later. The airway regions were segmented and the volumes were computed. RESULTS: The upper, middle, and lower airway volumes were significantly increased 2305 mm(3), 1144 mm(3), and 1915 mm(3), respectively. Similarly, oxygen saturation was increased (+5.3%) and the apnea/hypopnea index was improved (-4.2 events). All the observed modifications were statistically significant (P

CONCLUSION: Fungus ball can be suggested by the presence of the hyper-signal intensity portions in the fungal mass on T1WI in conjunction with dark-signal lesions surrounded by high-signal, hypertrophic mucosal walls in paranasal sinuses on T2WI. PMID: 31950777 [PubMed - in process]

AbstractPurposeTo evaluate and characterize anterior chest wall (ACW) joint ’s enthesopathy on CT scans in patients with DISH compared with age- and gender-matched control group.Material and methodsRetrospective evaluation for enthesopathy features of ACW joints —sterno-clavicular (SCJ), manubrio-sternal (MSJ), costo-sternal 1–7 (CSJ)—on chest CT scans of subjects with DISH (Resnick criteria) and of age- and gender-matched control subjects was performed. 183 subjects (DISH: 92, control: 91); male:female: 126:57, average age: 71.7 years (range 50–94 ) were evaluated. Total enthesopathy sco...

ConclusionsTransarticular SIJ biopsies are obtainable and can be directed towards areas with MRI abnormalities. They can be used to confirm inflammatory changes histologically. With the biopsy needles used, severe bone marrow sclerosis may hinder penetration to the cartilage, but bone marrow specimens can be obtained.

ConclusionsThere is a difference in mean error and reliability between radiologically measured values for anterior prominence and values measured directly with present methods. The use of our novel protocol based on bony acetabular landmarks, significantly improves the accuracy of measurement. This protocol may improve reproducibility and the accuracy of this measurement and aid in the decision between tenotomy or revision of the acetabular component.Level of evidenceIII, in vitro study comparing diagnostic tools.

This study aimed to reveal the correlation between the radiolucency area around the crown of impacted maxillary canines and dentigerous cysts using cone-beam computed tomography (CBCT). CBCT data were obtained from patients with impacted maxillary canines. Three points of five areas (tooth cusp area and buccal, lingual, mesial and distal areas of the crown) were randomly selected, and the distance between the point and the surrounding hard tissue was measured respectively. The mean values were recorded as the radiolucency area. These results were compared with the occurrence of dentigerous cysts during surgery. 58 patients...

We report a very rare case of LAM with malignant lymphoma. A 51-year-old female had medical history of recurrent pneumothorax and nephrectomy for a left renal angiomyolipoma and was diagnosed with LAM by video-assisted thoracoscopic surgery at the age of 30. She presented with left neck mass. Computed tomography and magnetic response imaging showed multiple enlarged cervical lymph nodes. 18F-fluorodeoxyglucose-positron emission tomography (FDG-PET) showed abnormal uptake in the mass. We suspected a malignant tumor or extrapulmonary lesion of LAM, and performed surgical biopsy. Pathologically, diffuse large B-cell lymphoma ...

ABSTRACT Objective: To describe a case of a male adolescent with symptomatic idiopathic intracranial hypertension (IIH) associated with obesity treated with bariatric surgery. Case description: A 16-year-and-6-month-old severely obese boy [weight: 133.6 kg; height: 1.74 m (Z score: +0.14); BMI: 44.1 kg/m2 (Z score: +4.4)], Tanner pubertal stage 5, presented biparietal, high-intensity, and pulsatile headaches, about five times per week, associated with nocturnal awakenings, and partial improvement with common analgesics, for three months. Ophthalmologic evaluation evidenced bilateral papilledema. Cranial computed tomography...

AbstractPurposeTo investigate whether anatomic and straight stems could reproduce the anteroposterior distance (AD) of the native femoral head and evaluate the effect of AD of the femoral head on range of motion (ROM) and bony impingement.MethodsThis retrospective simulation study included 64 patients who had undergone primary total hip arthroplasty between 2012 and 2014. Using computed tomography (CT) –based templating software, anatomic and straight stems were inserted with same alignment. AD of the head centre was compared between the two stems and native anatomy. Furthermore, post-operative ROM was calculated, an...
