Some variations of facial asymmetry are not considered an esthetic liability. So the aim of the present study is to determine a layperson's preference regarding transverse occlusal plane (TOP) orientation in fabrication of a complete denture. MATERIALS AND METHODS A total of 100 subjects who are edentulous and have enrolled for complete denture fabrication were selected. Photograph of the patient's face was obtained from the frontal perspective on the day of try-in. The image obtained was edited to orient the occlusal plane in three different cants, zero degree, two degrees, and four degrees to the inter-pupillary line (IL) and presented to the patient. The obtained results were statistically analyzed. RESULTS  The observed data was analyzed using Friedman's test and Wilcoxon test was used for comparing ordinal data between groups. There was a statistically significant difference in acceptance depending on angulation, χ2(2) = 183.2, p = 0.0001. CONCLUSION A cant of two degrees is not perceived by the subject but some subjects' preference of occlusal plane may be altered according to the commissural canting which cannot be incorporated in complete denture fabrication.

In this case report, a female child presented to the emergency department with persistent abdominal pain, normal lab studies, and unusual trans-abdominal pelvic ultrasound findings. Urgent exploratory laparoscopy was completed, demonstrating a torsed adnexa rotated around a very large, mature teratoma, with irregular masses consistent with fully developed teeth. Early recognition of atypical pediatric abdominal pain in the setting of equivocal diagnostic imaging findings and collaboration with surgical colleagues resulted in a positive outcome for this patient.

It is one of the most common cancers in men and women, and it is the main cause of cancer-related death in the United States of America. More than 90% of small cell lung cancer (SCLC) patients are elderly, with a current or past history of smoking. In Saudi Arabia, lung cancer incidence is low as compared to the global incidence. In 2013, the age-standardized ratio (ASR) was 1.8 per 100,000 for females and 5.5 per 100,000 for males. In our study, we aimed to assess the outcomes of SCLC at King Abdulaziz University Hospital (KAUH), Jeddah, Saudi Arabia. Methods This retrospective cohort study included all patients aged 14 years and older with a diagnosis of SCLC from 2007 to 2017 using electronic medical records at KAUH. Data analysis was performed using Stata SE, version 15.0 (StataCorp LLC, TX). The primary outcome of this study was the survival of patients diagnosed with SCLC. Survival was defined as the time the patient lived in montors, and to formulate a comprehensive survivorship care plan are required to develop better outcomes in survival and to improve the overall quality of life to pretreatment levels.

When such lesions are near one another but occupy different spinal compartments, significant challenges arise. We present the case of a patient with metastatic non-small cell carcinoma to the thoracic spine and an intradural meningioma occurring two spinal segments from each other. SHP099 in vitro A 66-year-old female presented with one month of progressive mechanical back pain and two days of lower extremity weakness and urinary retention. She was found to have a left upper lobe lung mass. An urgent biopsy demonstrated non-small cell lung carcinoma. MRI of her thoracic spine demonstrated a T9 intradural-extramedullary enhancing lesion simultaneously with a destructive lesion of the T11 vertebral body extending into the anterior epidural space with significant cord compression at T9 and T11. The patient was taken for an urgent posterior decompression from T9 to T11, T9 left-sided pediculectomy with resection of intradural tumor, T11 corpectomy with anterior cage reconstruction, and instrumented fixation from T7 to L2. The pathology from the T9 lesion demonstrated findings consistent with a meningioma while the T11 lesion confirmed metastatic non-small cell lung adenocarcinoma. The patient improved neurologically postoperatively and regained the ability to ambulate within one week of surgery. Pathologically distinct spinal lesions in close anatomic proximity, but in two separate compartments are exceptionally rare. We performed a simultaneous posterior approach for resection of the T9 meningioma and a T11 corpectomy for the metastatic lesion with rapid neurologic recovery.

It has achieved an almost iconic status due to its early discovery in the late, 19th century, and due to the abundance of material from the Morrison Formation of the western U.S.A., making Allosaurus one of the best-known theropod taxa. Despite this, various aspects of the cranial anatomy of Allosaurus are surprisingly poorly understood. Here, we discuss the osteology of the cheek region, comprised by the jugal, maxilla, and lacrimal. This region of the skull is of importance for Allosaurus taxonomy and phylogeny, particularly because Allosaurus has traditionally been reconstructed with an unusual cheek configuration, and because the European species Allosaurus europaeus has been said to be different from North American material in the configuration of these bones. Based on re-examination of articulated and disarticulated material from a number of repositories, we show that the jugal participates in the antorbital fenestra, contradicting the common interpretation.
