Smell Identification

We conducted a prospective study of 116 patients—61 men and 55 women, aged 17 to 64 years (mean: 26.4)— to investigate the effects of septoplasty on olfactory function in patients with septal deviation (SD). The Mladina classification system was used to define SD types, and olfactory function was assessed with the Brief Smell Identification test (BSIT). The BSIT, which includes 12 odorants, was administered preoperatively and at postoperative months 1 and 3. The most common SD types were types 2 (20.7% of patients) and 1 (19.0%), followed by types 3 and 5 (both 16.4%). At postoperative month 1, the mean BSIT score was significantly higher in men than in the women. For patients with types 1 and 2 SD, BSIT scores at 1 month were significantly lower than the scores preoperatively and 3 months postoperatively. For types 3 and 4, BSIT values were significantly higher at 3 months than preoperatively or at 1 month. For type 3 SD, the pre-operative mean score was significantly lower than those for types 1, 4, 5, 6, and 7; for type 2 SD, the BSIT score was significantly lower than those of types 5 and 6 only. At 1 month, the scores for types 2 and 3 were significantly lower than those for types 4, 5, 6, and 7. At 3 months, the BSIT score for type 2 was significantly lower than those of types 1, 3, 4, 5, and 6; the type 3 SD score at 3 months was significantly higher than those for types 1, 2, 5, 6, and 7. We conclude that septoplasty surgery for patients with a type 3 SD may improve olfactory function. In contrast, we found that olfactory function in patients with a type 2 SD did not improve to a satisfactory degree, even when good nasal patency was achieved with a corrected septum and an enlarged intranasal volume. Our findings should be investigated further in future studies.

Objective To study the clinical course of patients with Robin sequence (RS) during the first 6 months of life. Design A longitudinal prospective study of children with RS. Setting Hospital de Reabilitação de Anomalias Craniofaciais, Universidade de São Paulo, Bauru-SP, Brazil, 1997 and 1998. Patients Sixty-two children were studied from hospital admission to 6 months of age. Thirty-three (53.2%) presented with probable isolated RS (PIRS), 25 (40.3%) presented with syndromes or other malformations associated with RS, and 4 (6.5%) presented with RS with neurological involvement. Interventions The type of respiratory tract obstruction was defined by nasopharyngoscopy. The patients with type 1 and type 2 obstruction underwent nasopharyngeal intubation (NPI), and glossopexy was indicated in patients with type 1 obstruction who did not show clinical improvement with this procedure. Tracheostomy was indicated in patients with type 2 obstruction who did not show a good course after NPI, in patients with type 1 obstruction who did not show good course after glossopexy, and in patients with type 3 and type 4 obstruction. Results Prone position treatment (PPT) or NPI was the definitive treatment in 25 cases (75.8%) of PIRS and in 13 cases (52%) of syndromes or other malformations. Among the children with type 1 obstruction, 24 (51.1%) were submitted exclusively to PPT and 12 (25.5%) to NPI. With the type 2 groups, only one (12.5%) received PPT, and three (37.5%) were treated exclusively with NPI. All 15 infants treated exclusively with NPI (24.4%) presented with good weight, length, and neuromotor development. Conclusions Most patients with PIRS and type 1 obstruction improved without surgical intervention. NPI should be the initial treatment in all patients with RS with type 1 and type 2 obstruction who present with important respiratory and feeding difficulties.

Abstract The aim of this review study was to assess the past significant events on diabetes mellitus, transformations that took place over the years in the medical records of treatment, countries involved, and the researchers who brought about the revolutions. This study used the content analysis to report the existence of diabetes mellitus and the treatments provided by researchers to control it. The focus was mainly on three main types of diabetes (type 1, type 2, and type 3 diabetes). Ethical consideration has also helped to boost diabetic studies globally. The research has a history path from pharmaceuticals of organic-based drugs to metal-based drugs with their nanoparticles in addition to the impacts of nanomedicine, biosensors, and telemedicine. Ongoing and future studies in alternative medicine such as vanadium nanoparticles (metal nanoparticles) are promising.

Abstract This study was undertaken to evaluate the effect of microthread geometry of scalloped design implant on marginal bone resorption. Four types of scalloped design titanium implant specimens were prepared. The type 1 implant had a machined scalloped collar, type 2 had a sandblasted and acid-etched scalloped collar, type 3 had horizontal microthreads, and type 4 had parabolic microthreads, which are parallel with the scalloped conical margin. Two implants of a type were randomly installed immediately after extraction in the mandible of a beagle dog. Definitive prostheses were delivered immediately after surgery. After 12 weeks of healing, the dog was sacrificed and microtomography was performed. Type 4 specimens showed a marginal bone loss pattern definitively analogous to the scalloped margin. In this preliminary study, microthread geometry affected the marginal bone resorption pattern of scalloped design implants. However, additional specimens and more controlled conditions should be applied in future studies to confirm these results.

Abstract Objective: To describe a modified approach to the evaluation of adrenal nodules using a standard abdominal magnetic resonance imaging protocol. Materials and Methods: Our sample comprised 149 subjects (collectively presenting with 132 adenomas and 40 nonadenomas). The adrenal signal intensity index was calculated. Lesions were grouped by pattern of enhancement (PE), according to the phase during which the wash-in peaked: arterial phase (type 1 PE); portal venous phase (type 2 PE); and interstitial phase (type 3 PE). The relative and absolute wash-out values were calculated. To test for mean differences between adenomas and nonadenomas, Student's t-tests were used. Receiver operating characteristic curve analysis was also performed. Results: The mean adrenal signal intensity index was significantly higher for the adenomas than for the nonadenomas (p < 0.0001). Chemical shift imaging showed a sensitivity and specificity of 94.4% and 100%, respectively, for differentiating adenomas from nonadenomas. Of the adenomas, 47.6%, 48.5%, and 3.9%, respectively, exhibited type 1, 2, and 3 PEs. For the mean wash-in proportions, significant differences were found among the enhancement patterns. The wash-out calculations revealed a trend toward better lesion differentiation for lesions exhibiting a type 1 PE, showing a sensitivity and specificity of 71.4% and 80.0%, respectively, when the absolute values were referenced, as well as for lesions exhibiting a type 2 PE, showing a sensitivity and specificity of 68.0% and 100%, respectively, when the relative values were referenced. The calculated probability of a lipid-poor lesion that exhibited a type 3 PE being a nonadenoma was > 99%. Conclusion: Subgrouping dynamic enhancement patterns yields high diagnostic accuracy in differentiating adenomas from nonadenomas.

ABSTRACT Objective This study assessed how changing the Zirconia (Zr) substructure affected the color samples after they have been overlaid by the same shade of veneering ceramic. Materials and methods Three commercial Zr materials were tested in this study: Prettau® Zirconia (ZirKonZahn, Italy), Cercon (Dentsply, Germany) and InCoris ZI (Sirona, Germany). For each system, 15 disk-shaped specimens (10 × 1 mm) were fabricated. Three shades of A1, A2 and A3.5 of porcelain (IPS e.MaxCeram, IvoclarVivadent, USA) were used for layering the specimens. Five specimens from each type of Zr were layered with same shade of ceramic. Color measurements were recorderd by a spectrophotometer Color-Eye® 7000A (X-Rite, Grand Rapids, MI). Mean values of L, a, b color coordinates and ?E were recorded and comparisons were made. Results Differences in the ΔE were recorded for the same porcelain shade with different Zr substructures and affected the color of the specimens (p < 0.01, ANOVA). The maximum difference between the ΔE values for the A1, A2 and A3.5 shades with three types of Zr substructures was found to be 1.59, 1.69 and 1.45 respectively. Multiple comparisons of the ΔE with PostHoc Tukey test revealed a statistically significant difference (p < 0.05) between the three types of Zr, except between Type 2 Zr and Type 3 Zr for the Shade A1. The mean values of L, a, b and ΔE for the Prettau® Zirconia substructure were found to be the least among the three types. Conclusions The brand of Zr used influences the final color of the all ceramic Zr based restorations and this has clinical significance. How to cite this article Habib SR, Al Shiddi IF.
