Airway Dimensions

Objectives: This retrospective study investigated dimensional changes in the upper airway following Herbst appliance therapy in adolescents with Class II malocclusion and compared those changes with growth data. Materials and Methods: Lateral cephalograms from 44 Herbst-treated adolescents (23 boys, mean age = 13.3 ± 1.1 years, and 21 girls, mean age = 12.6 ± 1.1 years) were analyzed for the changes in the upper airway and craniofacial variables. Longitudinal cephalometric data of 34 untreated adolescents (15 boys, mean age = 12.6 ± 0.3 years, and 19 girls, mean age = 12.9 ± 0.4 years) were used as growth data for comparison. Results: Following treatment, significant changes were noted in most of the variables. Boys displayed greater downward movement of the hyoid bone than girls did (P = 0.021). Compared with the growth data, a greater increase in retroglossal oropharyngeal depth and hypopharyngeal depth was observed in boys and girls, respectively. Both displayed a decrease in the inclination of the soft palate and a smaller change in nasopharyngeal depth. Conclusion: Herbst appliance therapy enlarges the upper airway dimensions at two dissimilar sites in girls (oropharynx) and boys (hypopharynx). Boys display a greater increase in anterior and posterior facial heights than girls do, potentially accounting for the site dissimilarities. Moreover, a Herbst appliance improves the inclination of the soft palate and restricts the growth of the nasopharynx in both boys and girls.

Background and Aim: Tandem Spinal Stenosis (TSS) can be defined as simultaneous stenosis of two distinct spinal (cervical, thoracic and lumbar) areas. Characterized by an association of the spinal, radicular and medullary signs of the limbs, the planning of his surgery remains controversial. We reported the one that was set up on the cases observed at the Brazzaville Academic Hospital.  Methods and Materials/Patients: A retrospective study of 16 patients operated for TSS, from June 2009 to May 2019, was conducted. We analyzed the demographic, clinical, paraclinical, therapeutic and evolutionary data of these patients. Results: For ten years, a total of 16 patients (9 men and 7 women) with SST have been received. The average age was 57 years (ranged 41-72 years). The signs evolved for 17.6 months (13 and 30 months). These were lombo-sciatalgias in 15 cases, signs of medullary compression: cervical in 14 cases and thoracic in 2 cases. Medical imaging had objective 13 cervico-lumbar associations, two thoraco-lumbar associations and one cervico-thoracic. The surgery was performed in one stage in two cases and two stages in 14 cases. These were laminectomies for lumbar and thoracic disorders, discectomy or somatotomy in the cervical segment. The order of surgical management was cervico-thoraco-lumbar (cranio- caudal order). Signs improved in 13 patients and stabilized in 3 patients. Conclusion: TSS is not uncommon. It should be researched in a patient with bifocal spinal and radiculo-medullary signs. Their early surgical treatment, in one or two stages, yields satisfactory results.

The aim of this retrospective study was to evaluate the correlation between the midpalatal suture maturation and skeletal maturation in growing children aged 7 - 15 years and predict the maturational stages of the midpalatal suture corresponding to skeletal maturity assessed by the skeletal maturation indicators (SMI) and middle phalanx of the third finger (MP3) stages.The group of this retrospective study was consisted of randomly selected 132 male and 135 female in age from 7 - 15 years. The maturation of the midpalatal suture was evaluated by using images from cone-beam computed tomography (CBCT) while the skeletal age was assessed by hand-wrist radiography. CBCT images and hand-wrist radiographs used in this study were obtained from all subjects for orthodontic diagnosis before orthodontic treatment.The maturational stages of the midpalatal suture showed strong correlations with both SMI and MP3 stages. The correlation between the midpalatal suture maturation and SMI (Spearman’s correlation coefficient, ϒ<sub>S</sub> = 0.905, <i>p</i> < 0.05) was slightly greater than that of MP3 stages (ϒ<sub>S</sub> = 0.830, <i>p</i> < 0.05). There was a positive significant correlation between the midpalatal suture maturation and chronological age (ϒ<sub>S</sub> = 0.868,<i>p</i> < 0.05).CBCT for evaluation of the midpalatal suture maturational stages may be unnecessary in every pediatric patients because SMI and MP3 stages were both replaceable useful methods for assessing maturation of the midpalatal suture before orthopedic treatment. In this retrospective study, the diagnostic reliability of the SMI method for estimating midpalatal suture maturation showed better reliability than the MP3 method.

Objectives: This study aimed to assess the skeletal maturation by using salivary DHEAS levels and its correlation with existing skeletal maturity parameters represented by cervical vertebrae and MP3 region radiographs in adolescents in pre-pubertal and pubertal age groups. Methods: In this study, 80 children in the age range of 8 - 14 years were divided into two equal groups based on their chronological age as group I (pre-pubertal group) and group II (pubertal group). Pre-existing lateral cephalograms and medial phalanx of third finger (MP3) radiographs of their left hands were assessed. The levels of the DHEAS of each individual were analysed by ELISA kit. ANOVA with post-hoc Tukey’s test and student t-test were used for statistical analysis. P-value < 0.05 was considered significant. Results: The mean level of DHEAS values shown in the present study was 4.36 +/- 0.32 ng/mL in group I and 5.73+/-0.39 ng/mL in group II. This study showed that in group I, more subjects were in stage 1 of cervical vertebral maturation than stage 2 and there were significant differences between the two stages (P-value = 0.011); also, in group II, more subjects were in stage 3 than 4 and there were significant differences between the two stages (P-value = 0.017). This study revealed the highest salivary DHEAS levels to be in the F stage of pre-pubertal MP3 development in addition to the H stage of MP3 development in pubertal children. This study noted that there were significant differences for salivary DHEAS levels between males and females not only in pre-pubertal (P-value = 0.031), but also in pubertal stages (P-value < 0.001). Conclusions: Salivary DHEAS, like cervical vertebra and MP3 radiographs, can be used for growth assessment in young adolescents.

Introduction. The aim of this study is to present our treatment protocol for impalpable testis. Material and Methods. In a retrospective study we analyzed clinical data including diagnostic procedures, intraoperative findings, final diagnosis, treatment modality, and outcome of patients with impalpable testis who underwent surgery from January 2010 until December 2015. Results. Ninety-one patients were admitted under the diagnosis of impalpable testis. In 39 patients ultrasound detected testis in the inguinal canal and orchidopexy was done. In 25 patients (48.08%) laparoscopy showed the entrance of the spermatic cord into the inguinal canal. Open exploration of the inguinal canal was done, testicular remnant removed, and appropriate testicular prosthesis implanted. Twenty patients (20/52) underwent orchidopexy of the abdominal testis (46.51%), 4 of which underwent Fowler-Stevens procedure in two stages, and in 16 patients deliberation of the testis and spermatic cord was sufficient to place the testis into the scrotum. Conclusions. Excision of the testicular nubbin is highly recommendable, as well as implantation of the testicular prosthesis at the time of orchiectomy.

ABSTRACT Introduction Numerous appliances are present for the management of class II malocclusion. We have conducted a study to compare the clinical complications during treatment with either a removable mandibular acrylic splint (RMS) or with a cantilever Herbst (HC) appliance for the management of class II malocclusion. Materials and methods This study consisted of records of 114 patients (61 males, 53 females), who were divided into two groups. Group I received RMS and group II received HC for the treatment of class II, Division 1 malocclusion. They were further subdivided according to the telescopic system used [Dentaurum type I or propulsor mandibular abzil (PMA)] and fixation mode (splint with crowns or GripTite bands). Patients’ clinical records were assessed to identify clinical complications. Results The results of the study showed that the incidence of complications during treatment in both groups was statistically nonsignificant. The complications with either crown or band were also statistically nonsignificant. The Dentaurum group showed more susceptibility to complications than the PMA group. Conclusion The PMA telescopic system is more efficient as compared with Dentaurum. Complication resulting from Herbst appliance is independent type of appliance used and mode of fixation. Clinical significance Herbst appliance is the treatment of choice for class II malocclusion. How to cite this article Kanuru RK, Bhasin V, Khatri A, Dodda KK, Singh E, Grover S.

Cell Line Generation

B-lymphocytes normally synthesize small amounts of immunoglobulin, some of which is incorporated into the cell membrane where it serves as receptor of antigen. These cells, on contact with specific antigen, proliferate and differentiate to plasma cells which synthesize and secrete large quantities of immunoglobulin. The two stages of differentiation of this cell line (generation of B-lymphocytes and antigen-driven maturation to plasma cells) are clearly separable during ontogeny and in some immune deficiency diseases. The present report describes morphologic aberrations of B-lymphocytes in two diseases in which second stage differentiation is defective.
