INTRODUCTION Nicolau syndrome, also known as livedo-like dermatitis or embolia cutis medicamentosa, is a rare complication following the intramuscular or intra-articular injection of various drugs. CASE PRESENTATION In our case report we report the case of a 45-year-old Turkish woman who developed Nicolau syndrome after an intramuscular injection in her right gluteal region of single-dose dic...

Fosphenytoin (Cerebyx), is a water soluble prodrug that is rapidly and completely converted to phenytoin. This study reports the injection-site tolerance and safety of intramuscular fosphenytoin (> 10 mg/kg doses) in 60 patients requiring a phenytoin loading dose. Patients received injections at single or multiple sites with volumes ranging from 4 to 30 ml per injection site. The majority of pa...

Abscess formation following intramuscular injections is rare and they are most commonly seen in immunocompromised individuals. In this case series we present a cohort of three patients presented to us in a critically ill condition with an abscess due to intramuscular injection. Vancomycin resistant staphylococcus aureus was isolated from all three patients. These patients posed a major challeng...

A new technique for the treatment of diplopia secondary to cosmetic botulinum toxin A use is described. In this interventional case reports, two consecutive patients who developed diplopia after periocular cosmetic use of botulinum toxin A were treated with intramuscular botulinum toxin A injection into the antagonist extraocular muscle. Diplopia resolved in both patients in less than 1 week wi...

AIMS To examine depth of subcutaneous fat at gluteal intramuscular injection sites. DESIGN Retrospective study. SETTING General hospital. PARTICIPANTS 100 consecutive adults who had computed tomography of the pelvis. MAIN OUTCOME MEASURES Minimum distance between the surface of the skin and the nearest edge of muscle at intramuscular injection sites. RESULTS 12 patients had a ventrogl...

AIM To investigate effect of capsaicin-evoked masseter-muscle pain on intramuscular blood-flow (BF) at rest and during contractions. METHODS Eight healthy men (22-31 years) participated. BF was measured with Laser Doppler (Moor Instruments, UK) using a single-fibre probe inserted into the right masseter. Three BF probes were attached to the skin above right and left masseter and the right-mid...

The potential use of Yersinia pestis as a bioterror agent is a great concern. Development of a stable powder vaccine against Y. pestis and administration of the vaccine by minimally invasive methods could provide an alternative to the traditional liquid formulation and intramuscular injection. We evaluated a spray-freeze-dried powder vaccine containing a recombinant F1-V fusion protein of Y. pe...

A 56-year-old man noted a sudden decrease of vision in his right eye 4 hours after intramuscular triamcinolone acetonide (TA) injection. A diagnosis of unilateral nonarteritic anterior ischemic optic neuropathy (NAION) was made, and the patient was counseled to discontinue using TA. Examination for possible risk factors revealed controlled hypertension. Final visual acuity was finger counting a...

The efficacy of subcutaneous, intramuscular and intraperitoneal inoculation of heartwater infective blood or nymph suspensions was tested in 5 experiments involving a total of 199 sheep. The success rate of subcutaneous injections varied greatly (0-100%) in the different groups. However, it was found that certain additives to the inoculum, such as dimethyl sulphoxide or uninfective brain tissue...

BACKGROUND Although cervical trigger point intramuscular injections are commonly used to relieve localized neck pain, regional head pain relief from lower cervical paravertebral injections has not been reported previously. PURPOSE To evaluate the safety and efficacy of such injections in a selected group of patients with intractable head or face pain. METHODS In a series of patients with ch...
