Coats' disease in a patient with Cornelia de Lange syndrome.

A 16-month-old boy had the mental and physical retardation, low-pitched cry, phocomelia with syndactyly, hirsutism, low-set ears, bushy eyebrows, elongated eyelashes, blepharoptosis, and strabismus characteristic of Cornelia de Lange syndrome along with ophthalmoscopic findings characteristic of Coats' disease. Cryotherapy made the abnormal telangiectatic vessels less prominent, but macular scarring produced poor visual acuity. Occlusion therapy was unsuccessful.

Treatment of blepharospasm with botulinum toxin.

In 43 patients (81 eyes) with blepharospasm resistant to other forms of therapy, 149 outpatient injections of botulinum A toxin were given into the orbicularis oculi muscle. Subsequent follow-up periods ranged from ten to 210 days. Orbicularis oculi spasm, eyelid forced closure, and eyebrow spasm all decreased substantially over the first ten days following the initial injection. Patients with essential blepharospasm, hemifacial spasm, or previous surgery all responded in a similar fashion. This beneficial effect was transient, however, and additional treatment was required for sustained relief. Twenty-five patients received multiple injections with a mean interval of 65 days. Results of second and third injections were similar to the first in rapidity of onset and duration of effect. Complications were local, mild, and transient, and no systemic side effects were noted.

Eyelid suspension with a transposed levator palpebrae superioris muscle.

In patients with severe Marcus Gunn jaw-winking, ablation of the synkinetic eyelid movement requires surgical removal of a significant portion of the levator complex (muscle and aponeurosis). As an alternative to removing this tissue completely, the levator muscle can be transected approximately 25 mm above its tarsal plate insertion. The distal levator muscle and aponeurosis can then be used as a suspensory material to suspend the eyelid to the eyebrow.

The assessment of trichotillomania.

Trichotillomania is a disorder characterized by hair-pulling and resulting hair loss. Hair is usually pulled from the scalp, eyelashes, eyebrows, beard, and pubic area. Sufferers often resort to wearing wigs or elaborate hair styles and make-up to camouflage bald patches. It occurs more frequently in women and is associated with considerable distress. The two treatments of choice currently are pharmacotherapy and cognitive-behavioral therapy. The choice of assessment procedures includes self-monitoring, saving hairs, interview, observational rating, digital photograph and computer scoring, significant others' report, and standardized measures. Goals of assessment in trichotillomania and advantages and disadvantages of assessment procedures are discussed. The Trichotillomania Diagnostic Interview is presented as a standardized diagnostic interview.

Avulsion of the scalp treated by microvascular repair: the use of leeches for post-operative decongestion.

A 28-year-old fitter and turner was scalped at work. The scalp was avulsed from the nuchal area to the eyebrows in one piece. It was successfully replanted by microvascular surgery. Leeches were used to decongest the flap when venous drainage appeared inadequate during the first week. Only a small part of the flap eventually failed to survive and normal hair growth returned in all other areas.

Single artery replantation of totally avulsed scalp.

The treatment of choice for the avulsed scalp is microvascular replantation. After replantation there are numerous arterial anastomoses, with venous congestion. Usually an effort to establish inflow through two arterial anastomoses is made. We elected to anastomose one artery and multiple veins in each of our patients. We present three consecutive successful replantations of total scalp avulsion, using only one arterial anastomosis, and multiple veins. Surprisingly, two of the patients regained their ability to elevate their eyebrows actively.

Craniofacial injuries in unhelmeted riders of motorbikes.

We studied 1160 consecutive craniofacial injuries sustained by unhelmeted motorbike riders in Taipei, Taiwan, between 1990 and 1993, in order to investigate the distribution, type and severity of these injuries. The average age of the victims was 31 years (SD 13.2), with 84 per cent of them being between ages 16 and 45. The facial and cranial areas were defined as being separated by the line between eyebrows and ears. The incidence of facial injuries was the same as that of cranial injuries (both 68 per cent). While facial injuries occurred most often in the cheek and chin, most cranial injuries occurred in the forehead and parietal region. Although the majority of facial injuries resulted in mild brain injuries, they may also cause serious cosmetic problems, and some were associated with serious brain damage. Motorbike riders need good face protection. Since most motorbikes in Taipei travel relatively slowly, these results may also apply to bicyclists; in other words, cyclists may also need good face protection.

Reflex modification by acoustic signals in newborn infants and in adults.

This research asked whether the reflexive eyeblink elicited by a tap to the glabella (the flat region of skin between the eyebrows) is modified by acoustic signals which either precede or accompany the tap. Five experiments employing identical reflex modification procedures on neonates and adults suggest developmental differences in processing auditory stimuli. Neonates failed to exhibit reflex inhibition by either prior acoustic or tactile stimuli. Adults exhibited robust reflex inhibition to these same stimuli. Neonates, however, exhibited reliable reflex augmentation when mild (70 dB re: 0.0002 dyne/cm2) tones were presented simultaneously with the tap. For adults, tone intensities of at least 90 dB were necessary to obtain reliable reflex augmentation. The developmental processes implied by these findings are discussed.

Reflex augmentation of a tap-elicited eyeblink: the effects of tone frequency and tap intensity.

The amplitude of the human eyeblink elicited by a mild tap between the eyebrows can be increased if a brief tone is presented simultaneously with the tap. In two experiments we examined how this reflex augmentation effect varies with changes in the frequency characteristics of the tone and with changes in the intensity of the tap. We also examined how these effects change in the course of development. For newborn infants and for adults, fixed intensity tones with frequencies of either 1, 2, or 4 kHz produced equivalent amounts of reflex augmentation. Furthermore, while blink amplitude was an increasing function of tap intensity in both populations, the amount of reflex augmentation engendered by a simultaneously presented tone was independent of the intensity of the tap.

Cranial implant problems.

The common problems encountered during cranioplasty procedures have been reviewed and remedial procedures suggested. The problems or situations discussed include: implant selection and impressions, swelling and infection, integument thickness, distortion of plastic implants by autoclaving and seating guides, control of bleeding and swelling during operation, implant immobilization, eyebrow area involvement, dropping the implant, and inadequate skin flaps.

Sex differences in lateral facial facility: the effects of habitual emotional concealment.

Right-handed subjects attempted five different lateral facial actions: winking, eyebrow raising, mouth corner raising, nose wrinkling and mouth corner lowering. Males exhibited significantly greater left side facial facility than did females. The findings lend support to the suggestion that there is a neuroanatomical sex difference in the control of facial expression. For females only, the findings also support the suggestion that the habitual hiding of one's emotions produces greater lateral facial facility.

Actinic prurigo of the lower lip. Review of the literature and report of five cases.

Actinic prurigo (AP) is a chronic, familial, photodermatitis that primarily affects American Indians. It is more prevalent in young females and may be evident clinically as a pruritic lower lip cheilitis that typically does not respond to conventional therapy. Other clinical features associated with AP include conjunctivitis, alopecia of the eyebrows, and formation of pterygia. The histologic features of AP have been described as nonspecific. We are presenting five cases of AP in which the major clinical manifestation was a pruritic, unsightly lower lip cheilitis. All of our patients were American Indians. Three patients were from the same family. The youngest patient was 10 years old and the oldest was 69 years old. All five cases were characterized histologically by numerous germinal centers within the lamina propria and a dense perivascular plasma cell infiltrate. In four of the five cases, there was a moderate to dense infiltrate of eosinophils. All five patients had been generally unresponsive to conventional therapy. With the exception of the youngest patient, all had had the disease for at least several years. One patient, now deceased, had the lower lip lesion surgically removed for cosmetic reasons. To our knowledge, this is the first report in the dental literature that describes the clinical and histologic features of AP of lower lip.

Experimental transmission of Leishmania major to vervet monkeys (Cercopithecus aethiops) by bites of Phlebotomus duboscqi (Diptera: Psychodidae).

Experimental transmission of Leishmania major to vervet monkeys (Cercopithecus aethiops) was accomplished by bites of Phlebotomus duboscqi sandflies. Three-day-old, laboratory-reared P. duboscqi were fed on leishmanial lesions on hamsters infected with L. major. The flies were re-fed on monkeys 10 d after infection. Five adult male vervet monkeys were used in concurrent transmission trials. Two of the monkeys received subcutaneous inoculations with stationary-phase promastigotes (2 x 10(6) promastigotes in 0.1 ml of medium) on the base of the tail. Putatively infected P. duboscqi were allowed to feed on the remaining 3 monkeys at sites on the base of the tail and on the right eyebrow. Challenges by sandfly bites resulted in multiple leishmanial lesions at all bite sites and, consequently, more lesion area than was produced by needle challenges. Post-feeding dissection of sandflies indicated that multiple lesions could be caused by bites of a single fly, and that probing alone, without imbibing blood, was sufficient for transmission. These first experimental transmissions of L. major to vervets by bites of P. duboscqi demonstrate that sandfly challenge is an efficient alternative to needle challenge, making available a unique Leishmania-sandfly-non-human primate model for use in vaccine development.

Early scalp responses evoked by stimulation of the supraorbital nerve in man.

In 25 healthy volunteers the supraorbital nerve was stimulated and evoked potentials were recorded. Leads were placed on the scalp and along the ipsilateral eyebrow-mastoid line and were either referred to a non-cephalic reference (on the neck, or Cv7) or linked to form bipolar derivations. As template wave form was chosen the one obtained from derivation Cz-Cv7, which had an initial triphasic component with negative (SW1a), positive (SW1b), negative (SW1c) polarity (mean latencies 0.63, 0.95 and 1.43 msec), followed by 2 negative waves (SW2 and SW3, mean latencies of 2.20 and 2.89 msec). A final positive wave could be observed in most cases (SP4, mean latency of 4.08 msec). The records collected from the various derivations showed that each component (SW1, SW2, SW3 and SP4) had a different behaviour, thus suggesting separate origins. SW1 would originate from a volley travelling from the point of stimulation towards the mastoid, probably across the ophthalmic branch of the trigeminal nerve. The subsequent components would be generated by deeply situated structures: double pulse stimulation suggests that SW1, SW2 and SW3 are generated before the first synapse, whereas SP4 is a postsynaptic event. A strong similarity exists between the components evoked by stimulation of the supraorbital and the infraorbital nerves. Local anaesthetic block of the frontal nerve on the stimulated side and monitoring of the EMG activity of m. orbicularis oculi and m. frontalis ruled out any muscle contamination of the responses described in this paper.

Blink reflex far fields mimicking putative cortical trigeminal evoked potentials.

The R1 component of the blink reflex was evoked by stimulation of the left supraorbital and infraorbital nerves in 10 subjects. In addition, an artificial dipole was placed over the left eyebrow, in order to simulate the occurrence of the R1 component of the blink reflex. These electrical events were recorded at scalp locations Fz, F8, F7, C6, C5, referred either to Cv7 (seventh cervical vertebra) or to Fz. It was found that the blink R1 and the field of the artificial dipole had similar behaviour across the scalp; larger amplitudes were recorded ipsilateral to the stimulus from derivations referred to Cv7, but when referred to Fz larger contralateral amplitudes were measured. In the latter condition, the scalp-recorded R1 shows similar amplitude behaviour to electrical events originating from the cortex and hence its appearance may be deceiving.

Fractures of the zygomatic complex.

In 1973 methods for diagnosing and treating zygomatic complex fractures were reviewed, with emphasis on the lateral eyebrow incision for access to the zygomaticofrontal region. The following clinical update reviews alternative approaches to the zygomatic complex (coronal incision, upper eyelid incision), and current concepts of treatment for acute injuries and late deformities secondary to malunion.

Pain expression in patients with shoulder pathology: validity, properties and relationship to sickness impact.

This study dealt with the validity and correlates of facial expressions of pain. Twenty-four patients seeking treatment for gleno-humeral joint pain and 12 controls underwent a standardized physiotherapy assessment protocol involving active and passive arm movements, and experimental pain induced by pressure. Subjects rated pain intensity on each trial using categorical, sensory and affective scales. Independent of testing, they completed a questionnaire measure of sickness impact. Facial behavior was measured by an abbreviated version of the Facial Action Coding System. Facial actions that related to pain indices included eyebrow lowering, narrowing and closing of the eyes, lip pulling, nose wrinkling and mouth opening. Facial actions during clinical tests showed consistent relationships with sensory and affective pain scales. Greater physical disability was associated with more intense pain actions on active, but not passive, tests. The results support the validity and generality of facial measures of pain, show that they yield graded sensitive information and suggest that they encode information about the psychosocial context of pain problems. Theoretical implications of these findings are discussed.

Respiratory failure from severe organophosphate toxicity due to absorption through the skin.

Organophosphates are the most common group of chemicals involved in poisoning in Sri Lanka. Usually, poisoning is by ingestion for suicidal purposes, although accidental poisoning is not uncommon. Poisoning due to absorption through intact or damaged skin is rare. A 32-year-old man was admitted to a peripheral hospital following assault with a 100-ml bottle of insecticide called Monocrotophos, an organophosphate. He had a 2-in. long laceration just above his left eyebrow and there was spilling of the liquid contained in the bottle over his head and face. The liquid was wiped off but the head or face was not washed. After about 3 h the patient developed symptoms and signs of early organophosphate poisoning which were treated with atropine and pralidoxime. On the 3rd day, while on therapy, the patient developed severe weakness of limbs and respiratory distress needing intubation and assisted ventilation. The patient was transferred to the neurology intensive care unit of the General Hospital, Colombo, on the eighth day. His serum potassium levels were low and an ECG showed prominent U waves in all leads. The plasma cholinesterase levels were within 37.5-50% of normal even on the 20th day indicating severe exposure.
