Facial aesthetics following edgewise and Fränkel appliance therapy: the application of Chernoff faces.

This study investigates an application of the graphical technique of multivariate data description, 'Chernoff faces', to orthodontics. This method of pictorial presentation allows the simultaneous examination of several measurements in a single figure. Each variable is represented by a scaled feature of the human face: the size and position of the ears, eyes, eyebrows, nose, and mouth, as well as the face itself, are used to display data in a diagrammatic form. Using this method, the individual post-treatment results of 62 severe Class II division 1 cases treated by either Fränkel or Edgewise appliance therapy were compared. Nine cephalometric variables were chosen, describing the profile and the antero-posterior positions of the lower jaw and teeth, and stylized cartoon faces drawn for each child. These were compared with a control face prepared from untreated children of the same sex and age. Overall, children treated with Fränkel appliances showed a more normal relationship of the lips to Ricketts' aesthetic line and a greater prominence of the lower face. This difference between the two groups was most marked in the soft tissues. In a few cases, however, the appearance of the Edgewise treated children was indistinguishable from that of the controls. It is concluded that Chernoff faces, by portraying several pertinent aspects of data simultaneously, may be a useful adjunct to the presentation of orthodontic findings.

Complete remission of alopecia universalis after allogeneic hematopoietic stem cell transplantation.

This case report is on a 40-year-old male patient with chronic myeloid leukemia (CML) receiving an allogeneic hematopoietic stem cell transplantation (HSCT) in first chronic phase from an HLA-identical sibling brother. He suffered from alopecia universalis occurring 11 years previously. The alopecia involved all body hair, including eyebrows and eyelashes. Between day 40 and day 55 after transplantation, hair started to grow on the chin, eyelashes, and on the top of his head. Immunosuppression was stopped at 6 months because of cytogenetic relapse and incomplete donor chimerism with some renewed hair loss. He returned to full donor chimerism with mild chronic graft-versus-host disease and continued hair growth. With 2 years of follow-up he has remained in continuous remission. Chimerism analyses of hair follicles did not show any donor alleles. Alopecia universalis is probably a chronic autoimmune disorder, curable with replacement of the immune system with an allogeneic HSCT.

Pancreatic metastasis of Merkel cell carcinoma and concomitant insulinoma: case report and literature review.

BACKGROUND: Merkel cell carcinomas are rare neoplasm of neuroendocrine origin, usually observed in elderly people in areas with abundant sunlight, and predominantly located on the head and neck, extremities, and trunk. In many patients, a local recurrence after resection of the primary tumour and even distant metastases can be found. CASE PRESENTATION: We report an unusual occurrence of pancreatic metastases from a previously diagnosed Merkel cell carcinoma with the discovery of a concomitant insulinoma. An 82-year old lady suffered from recurrent attacks of hypoglycemia and presented with an abdominal mass, 2 years prior she had an excision done on her eyebrow that was reported as Merkel cell carcinoma. An extended distal pancreatectomy and splenectomy along with resection of the left flexure of the colon for her abdominal mass was carried out. Final histopathology of the mass was a poorly differentiated endocrine carcinoma in the pancreatic tail, in the peripancreatic tissue and in the surrounding soft tissue consistent with metastatic Merkel cell carcinoma in addition to an insulinoma of the pancreatic body. CONCLUSION: This is the first documented case of a metastatic Merkel cell carcinoma and a concomitant insulinoma, suggesting either a mere coincidence or an unknown neuroendocrine tumor syndrome.

Progressively intractable seizures, focal alopecia, and hemimegalencephaly.

We report a 3-year-old boy with the neurocutaneous combination of unilateral alopecia, ipsilateral hemimegalencephaly, and intractable seizures. He was born with an asymmetric hair pattern consisting of absent patches of hair, a small left eyebrow, and less eyelashes on the left eye; he had normal development until age 17 months, when he experienced right focal seizures with fever. Two months later, fever triggered new seizures characterized by flurries of head and body flexion and adduction of the right arm. He had left hand preference and language regression. EEG manifested left hemihypsarrhythmia, and MRI showed left hemimegalencephaly with marked enlargement of the temporal lobe with ventriculomegaly. Seizures were refractory to treatment with phenobarbital, adrenocorticotropic hormone, pyridoxine, sodium valproate, clonazepam, carbamazepine, phenytoin, and felbamate. This may represent a previously undescribed neurocutaneous syndrome.

Oxygen leakage around the laryngeal mask airway during laser treatment of port-wine stains in children.

The flash-lamp pumped pulsed dye laser is the current treatment of choice for cutaneous port-wine stains. In our practice, most children with these lesions are treated under general anesthesia. At energy levels used clinically, it is possible to ignite hair in the presence of supplemental oxygen; we are aware of four cases in which either the eyebrows or eyelashes were ignited during the administration of general anesthesia via a face mask. The laryngeal mask airway (LMA) recently has become widely available and this device might decrease the risk of fire during treatment of these lesions. We therefore designed this study to examine the extent of oxygen leakage under the mask during clinical cases, and to compare this with the leakage present with the LMA. A total of 20 patients aged 4 mo to 16 yr were studied on 26 separate occasions. During spontaneous ventilation, high concentrations of oxygen leaked around the mask in every case (mean 63% +/- 16%), but in only one case was a concentration more than 21% detected around the LMA (P < 0.001). During controlled ventilation with the LMA, oxygen leaked around the mask in 19% of cases. Use of the LMA markedly decreases the incidence of potential oxygen leakage into the laser field, and is recommended for use, with preservation of spontaneous ventilation, during these cases. We suggest measuring oxygen concentrations at the mouth for laser treatment of facial port-wine stains to confirm that the larynx has been isolated.(ABSTRACT TRUNCATED AT 250 WORDS)

Acupressure and preoperative parental anxiety: a pilot study.

In this randomized sham-controlled study we examined the anxiolytic and sedative effects of acupressure on parents in the preoperative holding area before their children's surgery. Sixty-one parents received acupressure either at the Yintang point (midpoint between the two eyebrows) or at a sham point. Anxiety (as measured by the Stait-Trait Anxiety Inventory), arterial blood pressure, and heart rate were assessed before and after the intervention and a Bispectral Index monitor was used to continuously monitor hypnotic sedation levels. Repeated-measures analysis of variance showed that parents in the acupressure group reported significantly less anxiety at 20 min post-intervention as compared with parents in the sham group (37 +/- 10 versus 45 +/- 13, P = 0.03). Bispectral Index values, heart rate, and arterial blood pressure, however, did not differ between the two study groups (P = not significant). We conclude that acupressure at the Yintang point may be used as a treatment for parental preoperative anxiety. Future studies are needed to quantify the magnitude and duration of the anxiolytic effect.

Dermoid cyst of the infratemporal fossa.

Dermoid cysts are rare benign tumours, they represent the simplest form of teratoma. Approximately seven per cent affect the head and neck region, within this region they are frequently encountered in the area of the lateral eyebrow, the orbit and the nose. A case of a 17-year-old girl who developed a rapidly growing facial swelling due to an infratemporal fossa dermoid cyst is presented. A review of the literature using Medline has not revealed any previous reports of similar cases. The lesion was completely excised using a lateral approach to the infratemporal fossa.

Radiation risks for the radiologist performing transjugular intrahepatic portosystemic shunt (TIPS).

The aim of this study is to evaluate the radiation dose to the interventional radiologist in transjugular intrahepatic portosystemic shunt (TIPS) concerning the risk of cancer and deterministic radiation effects and the relation to recommended dose limits. In 18 TIPS interventions radiation doses were measured with thermoluminescence dosemeters (TLD) fixed at the eyebrow, thyroid and hand of the radiologist without special lead shielding of these body parts and at the chest, abdomen and testes under the lead apron. The doses of the eye lens, thyroid gland and hand were assumed to be equal to the corresponding surface doses. The dose at the abdomen under the lead apron was used as an estimation of the ovarian dose. Effective dose equivalent was estimated by Webster's method. The estimated effective dose equivalent was 0.087 mSv and the effective dose 0.110 mSv. The risk of fatal cancer was of 10(-6) and the risk of severe genetic defect of 10(-7) for one single intervention. The maximum permissible number of TIPS interventions was 181, otherwise the dose limit for effective dose would be exceeded. When the radiologist performed more than 372 TIPS procedures per year for many years, the dose to the lens of the eye could exceed the threshold for cataract. If the interventionist performs a large number of TIPS procedures in a year, the risk of fatal cancer and developing cataracts becomes relatively high.

The temporal fossa in head and neck reconstruction: twenty-two flaps of scalp, fascia, and full-thickness cranial bone.

We reviewed 22 consecutive flaps based on the blood supply of the temporal fossa. Our purpose was to demonstrate reliability of the vascular supply and to illustrate the versatility of these tissues for reconstruction of specialized structures, including eyelids, eyebrow, ear, lips, oral lining, orbit, and mandible. For these complex problems, all but one patient required multiple-stage surgery to obtain their final aesthetic and functional results. All flaps proved reliable and versatile. Their advantages include proximity to the reconstructive site, ease of bilateral reconstructions, and well-camouflaged donor deficit. In particular, the ability to transfer vascularized full-thickness cranial bone for total or bilateral mandibular reconstructions presents an additional possibility for this difficult problem. We conclude that the reconstructive potential of these flaps is limited only by the surgeon's ingenuity.

Variations on the temporoparietal fascial flap.

An improved understanding of the vascular supply of the layers of the temporal fossa has increased the potential of this region for new and ingenious reconstructive techniques. Separate and independently vascularized layers of this region include hair-bearing scalp, glabrous skin, tempororoparietal fascia (and galea aponeurotica), temporalis muscle and fascia, and pericranium. Island flaps of glabrous skin and scalp provided esthetically appropriate tissue to cover a variety of defects. The malleable bulk of the subcutaneous fascial layers were combined with skin grafts to restore thin lining, and used as a vascularized bed for cartilage grafts in otherwise unsatisfactory recipient sites. Illustrative cases from our 5-year clinical experience are presented to demonstrate various combinations of the temporoparietal fascial pedicle with tissues from the temporal region to reconstruct the eyebrows, eyelids, orbits, cheeks, and lips.

Alopecia due to psychotropic medications.

OBJECTIVE: To review the literature and describe the incidence and nature of psychotropic drug-related alopecia to assist clinicians in their therapeutic decisions when this adverse event occurs. DATA SOURCES: A MEDLINE search (December 1966-March 1998), using each drug name and the keywords alopecia or hair loss, was conducted. A database from the Clarke Institute of Psychiatry in Toronto was also searched. Additional English-language articles were identified through the bibliography of the reviewed literature. Certain pharmaceutical companies were also consulted. STUDY SELECTION: All published case reports and review articles were considered for study evaluation. DATA EXTRACTION: When possible, details regarding psychotropic drug therapy, development of alopecia, and clinical outcomes were collected for each case. DATA SYNTHESIS: Hair loss from the scalp, eyebrows, and pubic area was identified as a possible, yet uncommon, adverse effect of most psychotropic medications. There are few effective management options for alopecia; however, resolution was achieved on discontinuation of the offending drug in almost all of the cases reported. Alopecia was perceived to be an undesirable effect by most patients, often resulting in poor compliance and hence therapeutic failures. CONCLUSIONS: Due to the self-limiting nature of mild to moderate hair loss with psychotropic medications, clinicians should consider continuing therapy if there is a good clinical response and the patient agrees with this decision. If severe alopecia occurs, it is recommended to discontinue the medication and pursue therapy with another agent. This is to ensure positive therapeutic outcomes and improved patient compliance.

Zygosity diagnosis in young twins by questionnaire for twins' mothers and twins' self-reports.

The present study deals with the determination of zygosity in twins of childhood age by simple questionnaire. The subjects were 224 twin pairs and their mothers, consisting of 159 monozygotic and 65 same-sex dizygotic pairs, identified by genetic markers including DNA samples. Mothers of twins responded to 19 questionnaire items dealing with twin similarity in 16 items about physical features and 3 items about the degree of similarity and frequency of being mistaken (confusion of identity) when twins were about 1 year of age. The twins themselves responded to three questionnaire items dealing with only confusion of identity items. The results of stepwise logistic regression analysis were as follows: the total accuracy of the mothers' questionnaire was 91.5% when using only the items dealing with confusion of identity. This accuracy was slightly lower than that obtained by twins' self-reports dealing with nearly the same question items of confusion of identity, answered by both twins separately with 93.3% accuracy. The total accuracy of mothers' questionnaire responses rose to 95.1% when we used all 19 items. In addition to "the frequency of being mistaken", two physical features, namely "shape of fingers" and "shape of eyebrow", were very informative. In conclusion, twin zygosity can be estimated by the use of the mothers' simple questionnaire with sufficient accuracy even in very young twins about 1 year of age.

[Eyelid alterations after the age of 50 years].

PURPOSE: To quantify the palpebral alterations occurring in subjects after the age of 50 years. METHODS: An observational study was done with 325 subjects older than 50 years. The data comprised measurements of intercantal distance, palpebral fissure length and height, external and internal eyelid angles, margin reflex distance (MRD) and total palpebral fissure area. Digital images were obtained with a Sony Lithium movie camera at the frontal view in ocular primary position, with the object of observation being located at the height of the pupil. The images were saved on tape, transferred to a McIntosh G4 computer and processed with the NIH 1.58 program. The data were submitted to statistical analysis. RESULTS: The subjects presented dermochalasis (96.5%), eyebrow ptosis (60.8%), orbital fat prolapse (50.0%) or eyelid ptosis (39.1%). The alterations were bilateral in 68.8% of the subjects. The intercantal distance was higher with age; the eyelid fissure length, the margin reflex distance and the external angle decreased in the elderly. The differences were more important on evaluating each eye separately. CONCLUSION: Intercantal distance increase and palpebral fissure length, margin reflex distance and total eyelid area decrease with age.

[Frequency of ocular changes in patients with Hansen's disease living in a colony hospital].

PURPOSE: To identify the frequency of ocular changes in patients with Hansen's disease, living in a colony hospital; to confirm the predilection for the anterior segment of the eye instead of the posterior segment. METHODS: Transversal study of 115 eyes of 58 in-patients at João Paulo II colony, Marituba-Pará, from August to October 1999. The epidemiologic data of this research were obtained from the patients' charts and from information obtained at clinical eye examination. All patients in this study were considered cured of Hansen's disease according to the Health Ministery criteria of cure. RESULTS: In 114 eyes (99.1%) ocular involvement was observed, the majority (77.2%) being the virchowian form. The most frequent ocular findings in the adnex were parcial madarosis (70.4%) and parcial eyebrow madarosis (59.1%). The most frequent ocular finding related to Hansen's disease was the decrease and/or absence of corneal sensitivity observed in 42.6% of the eyes, followed by paralytic midriasis (16.5%) found in the patients after surgery for cataract extraction; this finding was closely related to iris atrophy (8.7%), commonly found in these patients. CONCLUSION: The high prevalence of ocular involvement in Hansen patients, especially in virchowian form, indicates the need of complete assistance to these patients even after the resolution of the disease.

Recurring chemotherapy-associated alopecia areata: case report and literature review.

A 52-year-old woman with stage IIIC ovarian cancer and stage IA uterine cancer experienced recurring alopecia areata of her eyebrows, eyelashes, arms, legs, and pubic area beginning 5 months after completing chemotherapy with paclitaxel and carboplatin. The condition recurred in a cyclic fashion over the ensuing months. Alopecia is a well-recognized adverse event associated with chemotherapy; however, to our knowledge, this cyclic pattern of alopecia has not been reported in a patient with cancer. Our report of a cancer survivor who experienced cyclic alopecia areata indicates that this condition may be related to autoimmune changes instigated by chemotherapy. Oncology health care practitioners should evaluate unusual clinical cases of alopecia for underlying pathology.

Single-follicular-unit hair transplantation to correct cleft lip moustache alopecia.

OBJECTIVE: To present the case of an 18-year-old boy with a cleft lip scar and an obligatory need for facial hair who underwent single-follicular-unit graft hair transplantation that resulted in significant moustache hair restoration in a single procedure. SETTING: The surgery was performed in an outpatient private practice setting using oral sedation and local anesthesia. RESULTS: Advances in instrumentation technology and an increased understanding of the anatomical clustering of hair follicles into so-called "follicular units" containing one to six hairs per unit has resulted in a rapid expansion of hair restoration surgery into new areas including female-pattern alopecia, scarring alopecias, and cosmetic surgery scars. These new techniques can be employed to create natural-looking hair lines in front of artificial hair replacement systems; to improve unnatural looking, old "large-plug" hair transplants; and to correct discontinuity of eyebrows and hairlines in patients with congenital facial clefts. Increased awareness is needed to incorporate follicular-unit graft hair transplant surgery into the family of corrective surgery subspecialties.

[Treatment of facial nerve paralysis using static suspension methods].

After the injury of facial nerve, facial muscles are subjected to complex series of biochemical and histological changes, which lead to muscular atrophy if reinnervation is not restored. Facial palsy is very difficult to manage completely. Regardless this fact, the plan of correction has to be directed towards the following: restoration of normal function, normal facial appearance at rest, symmetry in voluntary movements as well as symmetry in involuntary and emotional movements. Static suspension methods were used in our study. All patients had unilateral complete facial nerve palsy but one female patient who experienced the palsy of frontal branch of n.facialis. This method was successfully used to lift the eyebrow, the lid and to improve lagophthalmus on the paralytic side, then the angle and paralytic part of the lip, to reinforce buccal wall of oral cavity as well as to reconstruct new nasolabial fold. The results were satisfactory and permanent.
