Reliability of Different Facial Measurements for Determination of Vertical Dimension of Occlusion in Edentulous Using Accepted Facial Dimensions Recorded from Dentulous Subjects

The study was undertaken to evaluate the reliability of different facial measurements for determination of vertical dimension of occlusion in edentulous subjects using accepted facial dimensions recorded from dentulous subjects. The hypothesis was that facial measurements can be used to obtain the vertical dimension of occlusion for edentulous patients where no pre-extraction records exist. A total of 180 subjects were selected in the age groups of 50–60 years, consisting of 75 dentate male and 75 dentate female subjects for whom different facial measurements were recorded including vertical dimension of occlusion and rest, and 15 edentulous male and 15 edentulous female subjects for whom all the facial measurements were recorded including the vertical dimension of rest and occlusion following construction of upper and lower complete dentures. The left outer canthus of eye to angle of mouth distance and the right Ear–Eye distance were found to be as valuable adjuncts in the determination of occlusal vertical dimension. The Glabella–Subnasion distance, the Pupil–Stomion distance, the Pupil–Rima Oris distance and the distance between the two Angles of the Mouth did not have a significant role in the determination of the occlusal vertical dimension. The vertical dimension can be determined with reasonable accuracy by utilizing other facial measurements for patients for whom no pre-extraction records exist.

Successful Treatment of Tracheal Stenosis with Slide Tracheoplasty after the Failure of Resection with End-to-End Anastomosis

The combined effects of inhaled irritant gases and heat in burn patients can result in the development of laryngotracheal strictures. Several factors could adversely affect the development of tracheal stenosis and cause the growth of granulation tissue. Yet the current treatment options for this condition are limited because of the paucity of case reports. We report here on a case of a patient who experienced recurrent upper tracheal stenosis after an inhalation injury. She displayed repetitive symptoms of stenosis even after several laryngomicrosurgeries and resection with end-to-end anastomosis. Finally, 5 yr after the burn injury, slide tracheoplasty was successfully performed and the postoperative check-up findings and the increased airway volume seen on imaging were all satisfactory.     

Laser division of congenital complete tracheal rings

Congenital complete tracheal rings are a rare and life threatening problem in young children and they are often challenging to manage. Whilst historically associated with high mortality rates increasing experience with this tracheal pathology has led to much improved survival rates and slide tracheoplasty has become the treatment of choice. We present 3 cases in which an open procedure was not deemed possible and they underwent laser division (CO2, KTP) of their complete rings. Two patients subsequently required stent insertion. All patients are alive and well at a mean follow up of 3 years and 5 months. Whilst laser division of complete tracheal rings has only been described in a small number of cases it may provide an alternative approach in patients who are not able to undergo an open procedure or in an emergency situation.     

Management of malaria threat following tsunami in Andaman & Nicobar Islands, India and impact of altered environment created by tsunami on malaria situation of the islands

Andaman & Nicobar Islands (Indian Territory) are situated in the Bay of Bengal and endemic for malaria with perennial transmission. Anopheles sundaicus which prefers to breed in brackish water, is known as the main vector for malaria and maintains high endemicity of malaria. Tsunami waves entered the inhabited coastal areas, caused heavy devastation and left large areas inundated causing exceptionally high breeding sources for vector mosquitoes of malaria. The disaster created a new habitat suitable for the proliferation of malaria and other disease-carrying mosquitoes besides making thousands of people homeless. They were living in temporary open shelters, getting more exposed to mosquito bites. The population already had existing high parasite load. Hence, there was a real threat of malaria outbreak in the area. However, malaria was effectively controlled due to strategic planning and timely remedial measures. Malaria situation was monitored closely and epidemiological data of three subsequent years from 2005 to 2007 after tsunami were analysed and compared with pre-tsunami malaria data from 1986 to 2004. In this paper, effect of tsunami on malaria profile in these islands has been discussed along with action taken for its control.     

BD focalpoint slide profiler performance with atypical glandular cells on SurePath Papanicolaou smears

BACKGROUND:

The FocalPoint Slide Profiler is an automated cervical cytology screening system that is approved for primary screening. It identifies up to 25% of slides as requiring No Further Review. However, few studies have evaluated FocalPoint performance with glandular abnormalities.

METHODS:

Sixty‐six SurePath Papanicolaou (Pap) tests with a diagnosis of atypical glandular cells were identified. A total of 172 Pap tests with a diagnosis of “endometrial cells present” were included as controls. Follow‐up histology was abnormal if diagnosed as high‐grade squamous intraepithelial lesions, adenocarcinoma in situ, carcinoma, or complex endometrial hyperplasia. The FocalPoint software ranked each case into 1 of 7 categories: quintiles 1 (high risk) through 5 (low risk), No Further Review, and Process Review.

RESULTS:

A total of 215 slides were qualified for review; 38 (57.6%) atypical glandular cells cases were abnormal on follow‐up biopsy, and 27 (71.1%) atypical glandular cells with abnormal follow‐up qualified for review; no cases were classified No Further Review, and 9 (33%) were ranked in quintile 1. Twenty‐three (82.1%) atypical glandular cells with benign follow‐up were qualified for review; 3 (11%) cases were classified No Further Review, and 4 (17%) were ranked in quintile 1. There was a statistically significant difference between the ranking of benign atypical glandular cells cases, abnormal atypical glandular cells cases, and control cases (P = .03). However, when collapsed into No Further Review versus all other quintiles, the differences were not significant (P = .20).

CONCLUSIONS:

The FocalPoint Slide Profiler did not classify glandular lesions with abnormal follow‐up in the No Further Review category. However, these cases were not preferentially ranked in quintile 1. FocalPoint‐screened slides need to be carefully reviewed for glandular abnormalities, regardless of the quintile ranking. Cancer (Cancer Cytopathol) 2010. © 2010 American Cancer Society.
