Botulin toxin A was introduced as a treatment in ophthalmology by Dr. Scott of San Francisco. One important application is in cases of blepharospasm, where the toxin is injected into the lateral parts of the lower and upper lid and, if necessary, over the eyebrows in a single dose of 1-2 nanograms, preferably using a needle under electromyographic control. The effect on the blepharospasm is visible after a few days and lasts for several months. The procedure can be repeated several times. The second application is in cases of strabismus. In paralytic strabismus, contracture of the antagonist of the paralyzed muscle can be weakened by local injection of botulin toxin with a coaxial electrode under electromyographic control. Good results were observed in cases of eye muscle disorders in endocrine ophthalmopathy. In concomitant strabismus (exotropia or esotropia) administration of botulin toxin is also possible although a certain paresis of the injected muscle has to be taken into account. The doses for strabismus vary between 1/2 and 2 nanograms of the toxin. The administration of botulin toxin either in blepharospasm or strabismus has no systemic side effects and is a safe procedure if performed under careful electromyographic control. First personal experiences in the treatment both of blepharospasmus as well paralytic strabismus and concomitant strabismus are reported.

In 2001, the incidence of primary and secondary syphilis increased in the United States for the first time in a decade. Increasing rates of early syphilis among men who have sex with men have been reported in many American cities, with similar outbreaks noted in Canada and Europe. In San Francisco, the increase has been particularly sharp and accompanied by an increase in the incidence of neurosyphilis. Early neurosyphilis develops within weeks to years of primary infection and primarily involves the meninges. Syndromes include syphilitic meningitis (often accompanied by cranial neuropathies), meningovascular syphilis (with associated ischemic stroke), or asymptomatic neurosyphilis. Late neurosyphilis occurs years to decades after exposure as cerebral or spinal gummatous disease or the classic parenchymal forms affecting the brain (general paresis or syphilitic encephalitis) or spinal cord and nerve roots (tabes dorsalis). Treponema pallidum, the causative agent, cannot be cultured in vitro, and microscopic techniques are laborious. Thus, diagnosis depends on serologic tests and cerebrospinal fluid (CSF) examination. The suboptimal sensitivity and specificity of these tests complicate diagnosis, particularly among patients coinfected with HIV. CSF examination should be performed to evaluate for neurosyphilis in all patients with positive serum syphilis serology and neurologic, ophthalmic, or tertiary disease, or in those who have failed therapy, and in HIV-infected patients with late latent syphilis or syphilis of unknown duration. Intravenous penicillin G is the recommended treatment for all forms of neurosyphilis and for syphilitic eye disease. An outpatient alternative, if adherence can be assured, is intramuscular benzathine penicillin with oral probenecid. Newer drugs that penetrate CSF, such as ceftriaxone or azithromycin, have not yet been adequately tested for neurosyphilis. Syphilis facilitates transmission of HIV (and vice versa), and thus all patients diagnosed with syphilis should be offered HIV testing.

Synkinetic movements are common among patients with incomplete recovery from facial palsy, with reported rates ranging from 9.1% to almost 100%. The authors propose the separation of the neural stimulus of the orbicularis oculi from that of the zygomatic muscular complex to treat eyelid closure/smiling synkinesis. This technique, associated with an anastomosis between the masseteric nerve and a central branch of the facial nerve, as well as with the use of a cross-facial nerve graft, resolves most of the spasms of the midface musculature, leading to a more relaxed tone when the mimic muscle is at rest and enhancing muscle excursion during voluntary and spontaneous smiling. Between 2011 and 2016, 18 patients affected by segmental paresis of the middle of the face underwent surgical treatment at the Maxillofacial Surgery Department of the San Paolo Hospital (Milan, Italy). Of these patients, 72.22% of cases with hypertone obtained partial to complete relaxation. Synkinesis was completely resolved in 83.33% of cases, and a significant improvement in facial movement was achieved in all patients. Neurorrhaphy of the masseteric nerve and the central branch of the facial nerve appears to produce favorable results. These initial data should be confirmed by further studies.
