Ofatumumab in poor-prognosis chronic lymphocytic leukemia: a phase IV, non-interventional, observational study from the European Research Initiative on Chronic Lymphocytic Leukemia.

We report the largest retrospective, phase IV non-interventional, observational study of ofatumumab therapy in heavily pre-treated patients with poor-prognosis chronic lymphocytic leukemia. Total number of patients was 103; median age was 65 years (range 39-85). Median number of prior lines of therapy was 4 (range 1-13), including, in most cases, rituximab-, fludarabine- and alemtuzumab-based regimens; 13 patients had been allografted. Of 113 adverse events, 28 (29%) were considered to be directly related to ofatumumab. Grade 3-4 toxicities included neutropenia (10%), thrombocytopenia (5%), anemia (3%), pneumonia (17%), and fever (3%). Two heavily pre-treated patients developed progressive multifocal leukoencephalopathy. On an intention-to-treat analysis, the overall response rate was 22% (3 complete response, 1 incomplete complete response). Median progression-free and overall survival times were 5 and 11 months, respectively. This study confirms in a daily-life setting the feasibility and acceptable toxicity of ofatumumab treatment in advanced chronic lymphocytic leukemia. The complete response rate, however, was low. Therefore, treatment with ofatumumab should be moved to earlier phases of the disease. Ideally, this should be done in combination with other agents, as recently approved for ofatumumab plus chlorambucil as front-line treatment for patients unfit for fludarabine. This study is registered at clinicaltrials.gov identifier:01453062.

The black widow spider bite: differential diagnosis, clinical manifestations, and treatment options.

Unrecognized and untreated black widow spider bites cause significant pain, impairment, and rarely death. The widow venom, a powerful neurotoxin known as a-latrotoxin, causes muscle pain, diaphoresis, tachycardia, flushing, and hypertension. Treatment is usually symptomatic with a combination of opioid analgesics and muscle relaxants. If symptom resolution fails, an equine IgG antiserum is available, but a high index of clinical suspicion coupled with a knowledgeable patient history often allows successful treatment, especially when the treating physician possesses awareness of this type of bite and its usual course and possible complications.

Cheilitis glandularis: a clinical marker for both malignancy and/or severe inflammatory disease of the oral cavity.

We report the case of an 84-year-old white male who underwent vermilionectomy for removal of a tumor, which proved to be squamous cell carcinoma. Chelitis glandularis related to marked actinic damage was noted at a subsequent visit. The presence of chelitis glandularis should be investigated for the presence of neoplasia, immunosuppression, or inflammatory diseases related to extremely poor oral hygiene.

The surgical looking glass: a readily available safeguard against eye splash injury/contamination during infiltration of anesthesia for cysts and other "porous" lesions of the skin.

BACKGROUND: "Breaks" in barrier precautions are a definite abrogating influence on the effectiveness of "universal precautions." Dermatologists and dermatologic surgeons are exposed to significant infectious agents on a daily basis, especially due to the high number of minor surgical procedures performed. Backsplash, spray, and eye splash of bodily fluids during these procedures place the surgeon at a high risk of contamination/infection via the conjunctival membranes. The surgical looking glass is a simple utility based on inexpensive equipment already in place in the physician's office which protects the eyes and face during infiltrative anesthesia or incision of cysts and other lesions. OBJECTIVE: To offer a simple and inexpensive utility to assist with protection from and reduction of contamination/infection of the ocular mucous membranes during surgical procedures. METHODS: Utilizing one or two readily available microscope slides overlying the injection site during local infiltrative anesthesia, backsplash or spray can be contained. RESULTS: This utility is effective in containment of backsplash or spray of anesthesia or bodily fluids during even minor surgical procedures. CONCLUSION: The surgical looking glass can enhance safety and promote "universal precautions" during even minor surgical procedures or infiltration of anesthesia into more porous areas or lesions for the practicing dermatologist or dermatologic surgeon. The pragmatic, practical, and inexpensive nature of the surgical looking glass invites its use on a daily basis by the practicing dermatologist.

Spontaneous clinical regression in chronic lymphocytic leukaemia.

Chronic lymphocytic leukaemia (CLL) is a B-cell disorder, which has a median survival of over 10 years from diagnosis for stage A disease. The natural history of stage A disease is generally indolent or only slowly progressive. It is less well known that CLL may undergo spontaneous regression. We report a series of 10 such cases (eight stage A and two stage B) followed at our institutions.
