Unilateral facial palsies were observed in three patients with positive serology for HIV. Two patients presented a second unilateral peripheral seventh nerve palsy after extraction of a tooth. Recovery was complete in each case. Peripheral neuropathies are present in 20% of cases with AIDS but cranial neuropathies are uncommon, affecting only 2 to 3% of patients. The seventh and the fifth are the most frequent cranial nerves involved. The reported isolation of HIV in the cerebrospinal fluid and from the nerve suggests a direct role of this agent. In this study an indirect mechanism such as a vascular spasm may also favour the occurrence of these facial palsies.

Cannabis has been advocated as a treatment for nausea, vomiting, wasting, pain and muscle spasm in cancer, HIV/AIDS, and neurological disorders. Such uses are prohibited by law; cannabinoid drugs are not registered for medical use in Australia and a smoked plant product is unlikely to be registered. A New South Wales Working Party has recommended granting exemption from prosecution to patients who are medically certified to have specified medical conditions. This proposal deserves to be considered by other State and Territory governments.

Spinal epidural abscess due to Streptococcus pneumoniae is extremely rare in adults. It typically occurs in the thoracic, lumbar or lumbosacral epidural spaces, and less frequently in the cervical epidural space. The principal causative microbial agent is Staphylococcus aureus, representing 70% of cases, while 1.6% of cases are caused by S. pneumoniae. We report the first case of an HIV-infected patient with a cervical spinal epidural abscess. The patient was a 43-year-old male with pneumococcal bacteremia and a metatarsal abscess. He reported cervical pain with muscle spasm during cephalic flexion and extension, fever and a painful tumefaction on the second metatarsal of the left foot. MRI confirmed that the retropharyngeal abscess extended to the cervical spinal epidural space. Antibiotic therapy with cefotaxime plus vancomycin was initiated and a transoral surgical approach was used to achieve retropharyngeal and local debridement of the metatarsal abscess. Blood and pus cultures were positive for S. pneumoniae. After 4 months of follow-up the patient remained asymptomatic, without clinical or MRI evidence of recurrence.

Controversy is associated with the issue of cannabis and cannabinoids in clinical care in the United States. Recent research has demonstrated the underlying mechanisms of cannabinoid analgesia via endocannabinoids, an endogenous system of retrograde neuromodulatory messengers that work in tandem with endogenous opioids. Additional receptor and non-receptor mechanisms of cannabinoid drugs have pertinent activity, including anti-carcinogenesis and neuroprotection, that may be of key importance in aging and terminal patient populations. The results of clinical trials with synthetic and plant-based cannabinoids suggest that the role of formulation and delivery system is critical in optimizing the risk-benefit profile of cannabinoid products. Synergy between opioids and cannabinoids may produce opioid-sparing effects, as well as extend the duration of analgesia and reduce opioid tolerance and dependence. This article reviews the mechanism of action of cannabinoids, examines marketed agents and those in clinical trials, and addresses their role in treatment of chronic pain, cancer, neurodegenerative diseases, and HIV/ AIDS. The ability of cannabinoid medicines to treat pain, associated sleep disorders, appetite loss, muscle spasm and a wide variety of other symptoms suggests that such agents may in the future play an important role in palliative care.

Ergotism is a complication of acute intoxication and/or chronic abuse of ergot derivatives. It expresses itself through a vasomotor syndrome with peripheral vascular disease which frequently involves extremities. We report four cases of HIV-1 infected patients treated with antiretroviral drugs including boosted-protease inhibitors who had self-treated themselves with ergotamine. They developed peripheral vascular disease symptoms and their pulses where diminished or absent in the physical examination. Arterial Doppler confirmed diffused arterial spasm in two of them. Ergotism following ergotamine-protease inhibitors association was diagnosed. Patients were treated through the discontinuity of involved drugs (protease inhibitors and ergotamine), calcium blockers; antithrombotic prophylaxis with enoxaparine, antiaggregant therapy with acetylsalicylic acid, and one of them received pentoxifylline and vasodilator prostaglandins infusion, with amelioration of the symptoms. We discuss the clinical presentation of this drug interaction, difficult to diagnose properly without a strong suspicion of its existence.

Clinical ergotism is a rare disorder, and clinical and therapeutic implications have continued to attract attention. The Holy Fire or St. Anthony's Fire was the primary vascular manifestation, causing burning pain and gangrene in the feet and hands related to the arterial spasm properties of ergot. The chronic use of ergotamine and migraine has also been associated with ergotism. Severe vasospasm and acute peripheral ischemia of the extremities can develop. However, in modern times, the spectrum of poisoning by alkaloids has broadened to include antiviral therapies in patients with HIV and abuse of stimulants. These changes have made taking an accurate medical history and conducting an accurate detailed differential diagnosis more essential. The purpose of this review is to highlight the importance of ergotism as a cause of peripheral vascular ischemia and analyze changes associated with this poisoning.
