Non-steroidal anti-inflammatory drugs are commonly prescribed in dental practice after minor oral surgical procedures such as tooth extraction. Diclofenac sodium is one of the non-steroidal anti-inflammatory drugs widely used for pain relief in dentistry. Although adverse reactions to these drugs are rare, at times they can cause a life-threatening phenomenon. Stevens-Johnson syndrome is one such potentially lethal adverse drug reaction. Most reported cases of analgesic-induced Stevens-Johnson syndrome were due to oxicams or propionic acid derivatives. There are very few detailed reports of Stevens-Johnson syndrome due to use of diclofenac. We report here a case of Stevens-Johnson syndrome which occurred due to use of diclofenac sodium. The clinical features of this condition and multidisciplinary management of the patient are described in brief. Source

Spindle cell carcinomas (sarcomatoid carcinomas) are rare tumours. It is a variant of squamous cell carcinoma which has spindled tumour cells, which simulate a true sarcoma, but are epithelial in origin. They are extremely uncommon in the head and neck region. Only five cases with maxillary origin have been discussed in the literature. As compared to squamous cell carcinoma of maxilla, this variant is associated with poor diagnosis and advanced disease at presentation, as is demonstrated in the case presented. There are no standard recommendations for management owing to the rarity of this histology. Surgery and radiotherapy form the mainstays of treatment. We report a rare case of spindle cell carcinoma involving the maxilla. Source

The calcifying odontogenic cyst (COC) occurs mainly as an intraosseous lesion in mandible or maxilla, but the peripheral variation of COC has also been reported. The confusion regarding its nature as cyst or tumour has not been resolved and a vast diversity has been noted in clinicopathological aspects of COC. We report a case of COCs with minimal mural ameloblastomatous proliferation in a 13-year-old girl, who presented with a painless swelling in the left jaw causing mild facial asymmetry. Source

The study of gross specimens is an integral part in learning oral pathology. Unfortunately their storage and handling using traditional formalin is discouragingly difficult. This review describes an alternative approach called "plastination" to study and teach gross specimens using silicone polymers. The process is simple, inexpensive, and can be carried out in any histology laboratory to produce dry, odorless, durable, life-like, maintenance-free, and nonhazardous specimens. Unfortunately the process of plastination for oral specimens has received little attention since its invention. Therefore, an innovative attempt on oral specimens using locally available resin was tried by us. The specimens remained well preserved in dry state without any color change. We recommend this process for any oral pathology department for maintaining museum and for both undergraduate and postgraduate training. Source

Objectives: Microscope work can be strenuous both to the visual system and the musculoskeletal system. Lack of awareness or indifference towards health issues may result in microscope users becoming victim to many occupational hazards. Our objective was to understand the occupational problems associated with regular use of microscope, awareness regarding the hazards, attitude and practice of microscope users towards the problems and preventive strategies. Material and Methods: a questionnaire based survey done on 50 professionals and technicians who used microscope regularly in pathology, microbiology, hematology and cytology laboratories. Results: Sixty two percent of subjects declared that they were suffering from musculoskeletal problems, most common locations being neck and back. Maximum prevalence of musculoskeletal problems was noted in those using microscope for 11-15 years and for more than 30 h/week. Sixty two percent of subjects were aware of workplace ergonomics. Fifty six percent of microscope users took regular short breaks for stretching exercises and 58% took visual breaks every 15-30 min in between microscope use sessions. As many as 94% subjects reported some form of visual problem. Fourty four percent of microscope users felt stressed with long working hours on microscope. Conclusions: The most common occupational concerns of microscope users were musculoskeletal problems of neck and back regions, eye fatigue, aggravation of ametropia, headache, stress due to long working hours and anxiety during or after microscope use. There is an immediate need for increasing awareness about the various occupational hazards and their irreversible effects to prevent them. © 2014 Versita Warsaw and Springer-Verlag Wien. Source
