Comparing the efficacy of sinus irrigation with traditional Caldwell-Luc procedure following odontogenic cyst surgery involving the maxillary sinus.

A large maxillary odontogenic cyst could intrude into the maxillary sinus. The traditional approach following surgery for such a cyst is the Caldwell-Luc procedure. However, the traditional CDL procedure is associated with more complications and damage of the sinus mucosa. The purpose of this study was to assess a new method with easier operation, which not only prevented postoperative infection but also caused less damage to the maxillary sinus mucosa. A large odontogenic cyst in the maxillary sinus of 40 patients was diagnosed through radiographic imaging and postoperative histopathology. Twenty patients were treated with maxillary sinus saline irrigation after surgery, while 20 patients underwent the traditional Caldwell-Luc procedure. The therapeutic efficacy was evaluated by clinical examination and radiographic imaging; the longest follow-up was 36 months. The postoperative reaction was evaluated. There was a statistically significant difference in facial swelling, visual analog scale (VAS) and temperature elevation between the 2 groups. Sinus irrigation following large odontogenic cyst surgery involving the maxillary sinus can serve as an alternative to standard CDL and has the advantages of fewer complications, reduced trauma, restoration of the mucosa and more satisfactory results.

Synthesis and Characterization of High-Efficiency Red Phosphorescent Iridium(III) Complexes with 1-(4-(Trifluoromethyl)phenyl)isoquinoline Ligand.

Two new tfmpiq-based bis-cyclometalated iridium(III) complexes, [(tfmpiq)2Ir(imdzppo)] (2a) and [(tfmpiq)2Ir(idzpo)] (2b) (where tfmpiq = 1-(4-(trifluoromethyl)phenyl)isoquinoline, imdzppo = 2-(imidazo[1,2-a]pyridin-2-yl)phenol, idzpo = 2-(2H-indazol-2-yl)phenol), have been synthesized and fully characterized. The single crystal structure of 2b has been determined. The relationship between the structures and photophysical properties of both complexes are considered, and the DFT calculations have been used to further support the deduction. These Ir(III) complexes emit red light with quantum yields of 39.9-51.9% in degassed CH2Cl2 solution at room temperature. Also, their emission originates from a hybrid 3MLCT/3LLCT/3LC excited state. All these results show that iridium(III) complexes 2a-2b are suitable for red-phosphorescent materials in OLEDs.

[Clinical effect of modified alveolar cleft repair with bone grafting].

PURPOSE: To evaluate the clinical effect of improved alveolar cleft repair with bone grafting. METHODS: Forty one cases with alveolar cleft treated by modified operation between 2008-2016 were included. The modified techniques were as follow: incision design, preparation of bone graft bed, bone removal and bone grafting, etc. The therapeutic effect was analyzed. RESULTS: The successful rate was 92.8%. After 6-12 months of follow-up, bone graft survived well with no obvious complications. CONCLUSIONS: Iliac bone is a good source for bone graft. Improvement of tight tension-free suture in bone bed is the key to surgical success.

Transvaginal hysterotomy for cesarean scar pregnancy in 40 consecutive cases.

To propose a novel procedure as a safe and effective treatment for cesarean scar pregnancy (CSP), a cohort study was initiated in patients diagnosed with CSP and treated with transvaginal hysterotomy from December 2009 to March 2013, either as a primary or secondary therapy. All diagnoses were confirmed by both sonography and pathology, either a gestational sac or residual tissue after termination of pregnancy or miscarriage in the cesarean section scar. Basic clinical characteristics and perioperative data were collected and analyzed. A total of 40 patients were included. The mean age was 32.88 ± 4.55 years. The mean size of gestational sacs of the CSP mass at diagnosis was 33.78 ± 13.14 mm. Mean serum ß-hCG level at diagnosis was 47379.73 ± 45285.10 IU/L. Mean operative time was 57.25 ± 24.52 min. Mean postoperative hemoglobin drop was 1.635 ± 0.906 g/dL. Complications were one case of bacteremia and two cases of hematoma. Mean hospital stay after surgery was 4.95 ± 2.62 days. Mean serum ß-hCG levels decreased by 88.5, 93.5, and 96.5 % at postoperative day 2, 4, and 6, respectively. All patients' ß-hCG levels returned to normal range within 1 month after surgery. Transvaginal hysterotomy with removal of ectopic pregnancy tissue and repair of cesarean scar defect is a promising approach to manage CSPs, with a short hospital stay, low postoperative pain, blood loss, and cost.
