Digital subtraction arthrography and arthrofluoroscopic dynamic observations on TMJ dysfunction syndrome

Digital subtraction arthrography and arthrofluoroscopic dynamic observation were performed for seventy cases with TMJ dysfunction syndrome. A comparative study between the findings of digital subtraction arthrography and the operative findings was carried out for eleven cases who underwent surgery. It has been found that digital subtraction arthrography can overcome the disadvantages of conventional arthrography and has important diagnostic value for TMJ dysfunction syndrome, especially for disc perforation. In addition. The procedure of digital subtraction arthrography, the normal and abnormal manifestations of digital subtraction arthrograms were described in the present study.     

T‐cell independent production of salivary secretory IgA after hematopoietic stem cell transplantation in children

This study examined the recovery of secretory IgA (S‐IgA) in saliva after hematopoietic stem cell transplantation (HSCT) in 35 children and young people between the ages of 3 and 27 years (mean = 13.6), and compared this recovery with that of serum immunologic constituents. Reference values for human salivary S‐IgA in saliva were obtained from 77 healthy control subjects between the ages of 7 and 25 years (mean = 11.4). In the 35 patients, a nadir of secretory IgA concentrations in saliva (S‐IgA) was observed between the 3rd and the 4th month, and a return to normal values 1 year after HSCT. Serum IgA concentrations reached their nadir in the 6th month, and normalized in the 18 months after HSCT. The recovery of T‐helper cells (CD4⁺/3⁺) was also delayed to beyond 18 months. We found a significant correlation between the reconstitution pattern of S‐IgA and that of T‐helper lymphocytes, but no correlation was found between the post‐transplant evolutions of S‐IgA and serum IgA, or between S‐IgA and T‐helper cells. The recovery of S‐IgA was more rapid than that of serum IgA and appeared to be T‐helper cell independent.     

Correlations between cephalic posture and facial type in patients suffering from breathing obstructive syndrome.

AIM: In this teleradiographic study, the authors investigate the correlations between facial kind, breathing pattern and cephalic posture. METHODS The research was conducted on a 94 schoolchildren sample. For each patient teleradiographic analysis in-L-L projection and rhinomanometric examination were performed. On the basis of clinical evidences, rhinomanometric results and nasopharyngeal space evaluation, the sample was divided into two groups: the first one included 36 oral breather patients (OB), the second one 58 nasal breathers (NB). RESULTS: The two groups do not differ significantly, with the exception of divergence values, frequently higher in OB than NB. The comparison of craniofacial features and cephalic posture among the groups points out to correlations between large craniocervical angle and skeletal Class II, mandibular retrognathia and increased gonial angle, respectively, not related to breathing patterns. CONCLUSION: According to the authors' results, it can be stated that morphological characteristics classically associated with breathing obstructive syndrome could be induced by altered cephalic posture instead.
