Nodular Fasciitis of Neck in Childhood.

Nodular fasciitis, is a benign, pseudo sarcomatous proliferative lesion of the soft tissue, which is frequently misinterpreted as sarcoma, both clinically and microscopically. It is a reactive lesion composed of fibroblasts/myofibroblasts and most commonly found in extremities and trunk. NF has been described in the head and neck region in 10-20% of cases. Many pathologists do not consider NF in the differential diagnosis of soft tissue masses arising in the Head neck region. NF that occurs in otherwise healthy individuals usually presents with a history of rapid growth, and is commonly found in the upper extremities and on the chest and trunk. The importance of otolaryngologists being aware of the existence of this entity in this area of the body is stressed. It has a confirmed perfectly benign clinical course, and simple excision, as tissue-sparing as possible, is the treatment of choice. A case of NF over the neck in a 05-year-old female not associated with trauma who presented with a localized mass over her left neck is presented

Malignant Melanoma of Nose and Paranasal Sinuses: 2 Case Reports

Malignant melanoma is one of the rare and highly aggressive diseases of the sinonasal cavity. High index of suspicion is required for diagnosis as the patient usually presents with non specific signs and symptoms. In the natural course of the disease, higher rate of loco regional recurrences and distant metastasis are seen making the overall prognosis of disease very poor. In reviewing the various treatment modalities used in the past, surgical resection of the tumour with postoperative radiotherapy is preferred one. Advances in surgery, radiotherapy and chemotherapy don’t have any impact on improved survival, which remains poor in this disease. We report two cases of malignant melanoma, which were treated at our institute

Aggressive Fibromatosis in Neck.

Aggressive fibromatosis (AF) is a locally aggressive infiltrative low-grade benign tumor that accounts for approximately less than 3% of all soft tissue tumors. In the head and neck region this tumor tends to be more aggressive and associated with significant morbidity. Aggressive surgery is a viable management option and may be successfully used as a single modality treatment, or in combination with radiotherapy. We report a rare case of AF in a 38 year old female, who presented with a painless mass over the left supraclavicular fossa, extending inferiorly into the thoracic inlet, which was excised successfully in toto with the help of cardiothoracic vascular surgeon (CTVS)

Development of Semi-Processed Steels for Electrical Lamination Applications at Tata Steel

Semi processed electrical steels are important materials in a verity of electrical machines. They offer better magnetization than equivalent fully processed grades and are subjected to decarburisation annealing treatment at customers' end for developing final magnetic properties. This paper reports the results of the silicon tree as well as silicon bearing semi-processed grades of cold rolled non-oriented(CRNO)steels developed at Tata Steel for electrical lamination applications. Both the grades were processed through LD steel making, secondary steel making (LF/RH), continuous casting, hot rolling, cold rolling, batch annealing followed by skin pass/temper rolling

Problems Facing by Construction Orgainsation and Construction Labour

Construction industry in INDIA is main component of GDP and covers huge amount of investment every year. On the other hand international labour organisations, NGO?s and socially working groups are continuously raising the question of human rights, labour safety, health cares and so many. In the similar way construction management facing the problems, as labour is the main force which execute the construction project on actual front line. But labour force is also responsible for project delay and cost over running in direct and indirect way as strikes of labours, not available at time, accidents at construction site and so may other reason

Allergic bronchopulmonary aspergillosis: the spectrum of computed tomography appearances

AbstractAlthough computed tomography (CT) of the thorax has been compared to plain chest radiography and bronchography for demonstration of central bronchiectasis (CB) in allergic bronchopulmonary aspergillosis (ABPA), the CT presentation of the disease is yet to be highlighted. With this in view, the CT appearances in 23 patients with ABPA were evaluated. The scans were assessed for bronchial, parenchymal and pleural abnormalities.Central bronchiectasis was identified in all patients, involving 114 (85%) of the 134 lobes and 210 (52%) of the 406 segments studied. Other bronchial abnormalities such as dilated and totally occluded bronchi (11 patients), air-fluid levels within dilated bronchi (five patients), bronchial wall thickening (10 patients) and parallel-line shadows (seven patients) were also observed.Parenchymal abnormalities, which had a predilection for upper lobes, included consolidation in 10 (43%) patients, collapse in four (17%) patients and parenchymal scarring in 19 (83%) patients. A total of six cavities were seen in three (13%) patients, and an emphysematous bullae was detected in one (4%) patient. The pleura was involved in 10 (43%) patients. Ipsilateral pleural effusion with collapse was observed in one patient, while in nine other patients, parenchymal lesions extended up to the pleura. Concomitant allergic Aspergillus sinusitis (AAS) was also detected in three (13%) of the 23 patients.Computed tomography of the thorax in patients with ABPA provides a sensitive method for the assessment of bronchial, parenchymal and pleural abnormalities, and should constitute a part of the diagnostic work of the disease

Prediction of Solubility of Carbonitrides in High Strength Low Alloy Steel

High Strength Low Alloy Steels are of particular interest for large submarines, offshore structures, line-pipe and other structural applications that require a combination of strength and toughness
