To Fly or Not to Fly? – A Review of the Pertinent Literature

Economies all over the world are moving towards a focus on services. Tourism has emerged as a major contributor to economies all over the world. This is why specific focus is being placed on tourism, as Destination Management Organizations (DMOs) concentrate their efforts on tourism. India has been one of the countries where the share of tourism in national income has steadily been increasing. As the national capital, the city of Delhi has a major role to play in the tourist inflow to the country, as well as within the country. Successful tourism marketing requires that the concepts of tourist destination and underlying factors are comprehended in detail. An analysis of the available, pertinent literature on the area shows the manner in which numerous factors come together to form the image of a tourist destination. In fact, it needs to be understood that image formation may be done differently for different consumers. This further necessitates a detailed study of the factors influencing tourist destination image.

AbstractThe presence of melanin pigment and melanocytic markers expression have been rarely reported in salivary gland tumors. Herein, two cases of carcinoma arising in pleomorphic adenoma of the parotid gland and showing diffuse expression of myoepithelial and melanocytic markers are described. The clinical-pathological clues useful in the differential diagnosis with melanoma are discussed. In addition, a review of the pertinent literature is also proposed, discussing the pathologic mechanisms potentially involved in this phenomenon.

Left Inguinal Region

Eccrine porocarcinoma (EPC) is an infrequent cutaneous neoplasm, and was described in 1963 by Pinkus and Mehregan. It is a rare type of skin tumor (0.005–0.01% of all skin tumors). Less than 300 cases have been described in the entire world medical literature. To our knowledge, no case of intergluteal cleft EPC has been reported in the literature in English and Spanish to date, so this would be the first reported case of such pathology. Metastatic EPC is less frequent, since only <10% of metastatic type have been reported and the rest as localized disease. The primary treatment of choice is surgical wide local excision of the tumor with histological confirmation of tumor-free margins. Prognosis is difficult to determine because of the rarity of EPC and the variations in natural history. There are no data to support the use of adjuvant chemotherapy or radiotherapy, and there are currently no agreed criteria to define patients at high risk of relapse. We present a 67-year-old man with intergluteal cleft eccrine tumor by biopsy. Metastasis to left inguinal region and lung was reported by contrasted abdominal and chest computed tomography. He started chemotherapy based on etoposide, vincristine, carboplatin. A review of pertinent literature is provided.

✓Meningeal melanocytomas are rare tumors and malignant transformation of these lesions is even rarer. The authors report on a case of a 57-year-old man who presented with a melanocytoma located at the L5–S1 level. After gross-total resection of the tumor, it recurred 1 year later as a malignant melanoma. In addition, multiple subcutaneous metastases were found at that time. The patient was treated with radiation therapy (5000 cGy). Five months later metastases in the liver and the left ninth rib were discovered. The pertinent literature is reviewed and disease criteria are presented to distinguish meningeal melanocytoma from malignant melanoma and from meningiomas or schwannomas containing melanotic pigment. Patients and investigators should be cautioned that a meningeal melanocytoma may recur and transform into a malignant melanoma.

Introduction: Extraneural metastases of glioblastoma are very rare clinical entities, especially in pediatric patients. Because of their rarity, they can be confused with other pathological processes. Case Presentation: We report a case of 16-year-old boy with extensive extraneural metastases of glioblastoma. Lung, liver, cervical lymph nodes, skin, and bone metastases were detected in the patient. Conclusion: We describe the presentation, evaluation, and diagnosis of this rare condition with regard to pertinent literature.

✓ Isolated cervical spinous process fractures are common, but are usually considered to be inconsequential. Although such fractures may produce pain, complete recovery without residual symptoms is expected after conservative treatment, and neurological injury does not usually occur. The case of a patient with a persistently symptomatic C-2 spinous process fracture that required surgical treatment for pain relief is reported. A review of the pertinent literature illustrates with unusual clarity the interactions of social, political, and economic forces associated with this medical condition.

Limited Application

The triammonium salt of aurin tricarboxylic acid, commonly referred to as aluminon, forms a dye that has been used for the colorimetric determination of Al(III) species. We have reviewed the pertinent literature on the reaction of aluminon with respect to the metallic species that form colored aluminon complexes. The effects of experimental variables, such as time, temperature, and pH, upon the color development of the aluminon complex are also presented. Organic and inorganic species, particularly Be(II) and Fe(III), which can affect color formation, are described. The use of aluminon as a histochemical staining agent for the detection of aluminum requires verification by atomic absorption spectrophotometric analysis or other quantitative techniques.
