Primary non-Hodgkin lymphoma of the humerus following traumatic injury: case report

HEMATOLOGICAL ONCOLOGY, Issue 3 2003
V. Stemberga
Abstract A case of primary non-Hodgkin lymphoma of the right humerus which occurred in a 21-year-old male patient after an impact to the right shoulder in a car accident in July 1983 is described. Seventeen years after the injury, due to a civil lawsuit, the biopsy material was revised. Immunohistochemical analysis showed CD20 and CD79a positivity on large pleomorphic cells, while small reactive lymphocytes were CD3, Bcl-2 and CD20 positive. Molecular analysis carried out with PCR revealed a monoclonal B-lymphocyte population. The diagnosis of diffuse large peripheral B cell lymphoma of the bone was confirmed. The present case concurs with the literature on primary bone lymphoma, in which the diagnostic problem, trauma-related presentation and an excellent prognosis of malignant tumour are emphasized.

Condylar resorption during active orthodontic treatment and subsequent therapy: report of a special case dealing with iatrogenic TMD possibly related to orthodontic treatment

JOURNAL OF ORAL REHABILITATION, Issue 5 2005
Y. H. SHEN
summary, A 28-year-old female underwent orthodontic treatment for approximately 22 months. During the later stages of this treatment, the patient reported right shoulder and neck-muscle pain. In addition, temporomandibular joint disorder (TMD) with a ,clicking' sound during mastication commenced 5 months prior to treatment completion. Specific medication to deal with these symptoms was suggested by medical specialists, as were some stress-relief methods, although the pain still progressed, and subsequent clinical and radiographical examinations were undertaken by another orthodontist. Right mandibular condylar resorption was observed from both the panorex and temporomandibular joint (TMJ) radiographs. No clinical signs of rheumatic disease were observed, although bruxism was noted. Following the termination of the orthodontic treatment by the second practitioner, the patient was treated with splint therapy 1 month subsequent to which, the previous symptoms of pain in the shoulder and neck, and the clicking sound during mastication had subsided. During the 14-month period of splint therapy and follow-up, new bone growth in the right condyle was observed from radiographs. [source]

A Randomized, Double-blind, Sham-controlled Trial Comparing Two Screening Devices for Radiation Contamination

ACADEMIC EMERGENCY MEDICINE, Issue 9 2010
Philip Salen MD
Abstract Objectives:, This exploratory study compared the screening ability of a newly introduced radiation detection portal with a traditional Geiger counter for detection of radiation contamination in the setting of a mass casualty training exercise. Methods:, Following a pretrial evaluation of interobserver reliability for Geiger counter use, 30 volunteers were randomly assigned to don gowns containing three disks, each of which was either a sham resembling the radioactive samples or an actual cesium-137 sample; each subject participated a minimum of four times with different gowns each time. Each subject underwent standard radioactivity screening with the Geiger counter and the portal. Results:, Interobserver reliability was excellent between the two Geiger counter screeners in the pretrial exercise, correctly identifying 101 of 102 sham and radioactive samples (, = 0.98; 95% confidence interval [CI] = 0.94 to 1.00). For radioactively labeled subjects across all bodily locations, the portal (43/61, or 70.5%; 95% CI = 58.1% to 80.5%) was less sensitive than the Geiger counter screening (61/61, or 100%; 95% CI = 92.9% to 100%), which resulted in a portal false-negative rate of 29.5%. For radiation detection in the posterior thorax, the portal radiation screening (4/19, or 21.1%; 95% CI = 8% to 43.9%) was less accurate than the Geiger counter (19/19, or 100%; 95% CI 80.2% to 100%). In contrast, there were no major differences between the portal and the Geiger counter for radiation detection at the left shoulder, right shoulder, or sham (nonradiation) detection. There were no false-positive detections of the sham-labeled subjects for either device, yielding a specificity of 100% for both screening modalities. Conclusions:, Geiger counter screening was more sensitive than, and equally specific to, radiation detection portal screening in detecting radioactively labeled subjects during a radiation mass casualty drill.

An Unusual Complication of Sinus Arrest Following Right-Sided Stellate Ganglion Block: A Case Report

PAIN PRACTICE, Issue 3 2004
Ashok K. Saxena MD
Abstract: We present a case of a 29-year-old female patient who had presented to us for the management of her chronic right shoulder,hand pain and developed a sinus arrest following a right-sided stellate ganglion block (RSGB). This patient on receiving a diagnostic RSGB via the anterior paratracheal (C6) approach developed sinus arrest followed by apnea and unconsciousness. On institution of resuscitative measures involving tracheal intubation, positive pressure ventilation, cardiac massage, and intravenous atropine, spontaneous cardiac activity recovered in about 3 minutes. Other signs and symptoms resolved fully in a total of 10 minutes. She had persistent postural hypotension lasting for about 24 hours requiring bed rest and was discharged about 36 hours after the procedure, without any adverse sequelae. As the sinus node is supplied by the right-sided sympathetic chain, its blockade probably resulted in unopposed parasympathetic activity leading to asystole. Available evidence of the role of right stellate ganglion in regulation of cardiac electrophysiology and functioning is also discussed. [source]

A rare case of recessive dystrophic epidermolysis bullosa and verruciform xanthoma

CLINICAL & EXPERIMENTAL DERMATOLOGY, Issue 1 2009
S. D. Orpin
Summary A 33-year-old man with recessive dystrophic epidermolysis bullosa presented with a 3-month history of an enlarging mass within scarring on the posterior aspect of the right shoulder. The clinical appearance of the mass with an almost cobbled, verrucous surface, and its rapid evolution suggested the development of a squamous cell carcinoma (SCC) in a chronically scarred site. Histopathological examination of a biopsy taken from the lesion subsequently revealed it to be a verruciform xanthoma. This case shows that benign phenomena can mimic SCC and underlines the need for a biopsy to be taken promptly. [source]
