Abstract

Benign mixed tumors of the salivary glands are generally regarded as indolent and harmless neoplasms. A subset of benign mixed tumors, however, can undergo carcinomatous transformation (that is, carcinoma ex-mixed tumor). Even more rarely, a mixed tumor that is seemingly benign at the microscopic level will metastasize like a true carcinoma (that is, metastasizing mixed tumor [MZMT]). Despite the benign appearance of the metastatic implants, there is usually little doubt regarding their true nature and origin. Patients invariably have had a mixed tumor removed from the parotid or some other salivary gland, and metastatic spread is usually preceded by multiple episodes of local tumor recurrence. We report a case of MZMT that presented as a solitary kidney mass. In the absence of a previous or concurrent salivary gland tumor, its metastatic nature was not appreciated and it was regarded as an unusual but benign kidney adenoma. One year after removal of the kidney mass, the patient presented with signs and symptoms of an aggressive parotid tumor. Pathologic examination of the tumor in the parotid demonstrated a high-grade carcinoma arising from a mixed tumor. This case underscores the importance of considering MZMT when a seemingly benign mixed tumor is encountered at a nonsalivary site, even in patients without a supportive history. Failure to do so may cause an unnecessary delay in primary tumor diagnosis and management, allow the primary tumor to progress toward a more malignant phenotype, and deny the patient a high expectation for a complete cure.

Abstract

Phosphorus is considered among most vital macro-elements, which is mandatory for successful plant growth. Although it is plentiful in soil both in its organic and inorganic form but its larger fraction is unavailable to plants. Different phosphate solubilizing micro-organisms (PSMs) residing in soils can change the chemical nature of these organic and inorganic phosphate compounds and make them available to plants. Only bacteria are focus of this study which investigates the antifungal potential of these phosphate solubilizing bacteria (PSB). These These PSB can perform important role in defending plant roots from pathogenic fungi in an environment friendly mode. Hence, help in minimizing the dependence on environmentally harmful and expensive phosphate fertilizers and fungicides. From a plenty of purified PSB isolates only elite strains with higher phosphate solubilization index have been selected for identification and for bio control studies. Alternaria alternate (A. alternate ), Macrophomina phasiolina (M. phasiolina), Fusarium oxysporum (F. oxysporum) and Sclerotium rolfsii (S. rolfsii) had been grown simultaneously along with six selected PSB strains including Burkholederia cepacia (B. cepacia), Citrobacter freundii (C. freundii ), Enterobacter aerogenes (E. aerogenes), Klebsiella pneumonia (K. pneumonia), Proteous vulgaris (P. vulgaris) and Acinetobacter lwoffi (A. lwoffi). The completely restricted growth of mycelia of these plant pathogenic fungi was observed in the presence of selected bacterial strains which have been found as effective bio control agents. The results of the presented work strongly encourage the need to explore more PSB strains with higher phosphate solubilizing potential and deadly effective against broader range of plant pathogenic fungi.

Abstract

Genetically modified organisms have become obligatory to adopt certain precautions to overcome the risks related to release of GMOs. Through this study, an attempt was made to evaluate bio-safety concerns of transgenic sugarcane with insect resistant gene, Cry1Ac. In short term feeding trial of 120 days, 20 broiler chicks divided into four random groups were caged separately. Group-I fed on commercial chicken diet; group-II fed on non-transgenic sugarcane diet; group-III fed on transgenic diet (commercial to transgenic ratio was 1:1) while group-IV was fed on high dose transgenic diet (commercial to transgenic ratio was 1:2). Body weights of chicks increased normally in all four groups during the course of study. Biochemical tests and molecular tests done on chick's blood reported no significant difference among assorted groups. At the termination of the experiment, chicks were slaughtered and dissected vital organs were used for histological studies. It was found that tissues belong to group 3 and 4 were morphologically and histological similar to group 1 and 2. Also, no mRNA expression was observed in total RNA isolated from chicken's tissues. These findings suggest that there was no deleterious or harmful effect of the GM sugarcane on the chick's health and no transgene fragment has transferred from GM crop to animal's blood neither in their vital tissues. Conclusively, it is suggested that at least in short-term period feeding trial, the genetically modified sugarcane doesn't not have adverse effect on animals feeding them. [ABSTRACT FROM AUTHOR]

164. Remediation of problematic residents--A national survey.

Author

Bhatti, Nasir I., Ahmed, Aadil, Stewart, Michael G., Miller, Robert H., and Choi, Sukgi S.

Abstract

Objectives/hypothesis: Despite careful selection processes, residency programs face the challenge of training residents who fall below minimal performance standards. Poor performance of a resident can endanger both patient safety and the reputation of the residency program. It is important, therefore, for a program to identify such residents and implement strategies for their successful remediation. The purpose of our study was to gather information on evaluation and remediation strategies employed by different otolaryngology programs.Study Design: Cross-sectional survey.Methods: We conducted a national survey, sending a questionnaire to the program directors of 106 otolaryngology residency programs. We collected information on demographics of the program, identification of problematic residents, and remediation strategies.Results: The response rate was 74.5%, with a 2% cumulative incidence of problematic residents in otolaryngology programs during the past 10 years. The most frequently reported deficiencies of problematic residents were unprofessional behavior with colleagues/staff (38%), insufficient medical knowledge (37%), and poor clinical judgment (34%). Personal or professional stress was the most frequently identified underlying problem (70.5%). Remediation efforts included general counseling (78%), frequent feedback sessions (73%), assignment of a mentor (58%), and extra didactics (47%). These remediation efforts failed to produce improvement in 23% of the identified residents, ultimately leading to their dismissal.Conclusions: The apparent deficiencies, underlying causes, and remediation strategies vary among otolaryngology residency programs. Based on the results of this survey, we offer recommendations for the early identification of problematic residents and a standardized remediation plan.Level Of Evidence: NA. [ABSTRACT FROM AUTHOR]

165. Impact location, energy, and damage detection in a smart structure

Abstract

A sensor at a fixed location in a complex structure records a complicated but unique wave pattern containing information about impact location, imparted energy and any damage created by an impact event. An intelligently designed hybrid neural network system is capable of extracting this information from the sensory signal. Such a system based on a generalized regression neural network (GRNN) is described for the purpose of impact location, energy, and damage detection. A Northrop Grumman test article is utilized to demonstrate capabilities of the system. The system performance evaluation based on the preliminary experiments is very encouraging. Further experimental evaluations of the system are planned and are described in this manuscript.© (1996) COPYRIGHT SPIE--The International Society for Optical Engineering.

Abstract

Methods: Mastoidectomy evaluations based on a previously validated taskbased checklist were obtained for nine residents from post-graduate year (PGY) 2 and 3 over a period of 3 years. Average scores were measured over time and learning curves were generated using scatter plots and non-parametric smoothing techniques. A 5-item survey was conducted to explore various residents’ related characteristics such as interest.
