The VITOM® exoscope in oculoplastic surgery: the 5 year Coventry experience.

BACKGROUND: Intraoperative imaging is a desirable tool in oculoplastic surgery; however, there are few modalities which allow surgeons to capture and edit the images in real time without compromising the sterility of the surgical field. We describe the set-up of the VITOM® exoscope system based on our 5 years' experience of using it as an effective intraoperative video imaging and teaching modality for extraocular surgery. METHODS: The VITOM® is a specially designed exoscope mounted onto a versatile mechanical arm. It is attached to a high definition (HD) digital camera displayed on the HD video monitor of a standard endoscopy stack. This technology has been utilised in other surgical subspecialties, but there is no documented use within extraocular surgery. RESULTS: The exoscope was simple to set-up and allowed real-time recording and editing with an HD image display system. The theatre team were able to view the precise surgical steps, contributing to improved theatre flow. Trainees reported that the VITOM® images significantly improved their visualisation and understanding of key surgical anatomy and steps. CONCLUSIONS: Our experience showed that the VITOM® exoscope is an excellent intraoperative video imaging and teaching aid, as it allows real-time capture and editing of open surgery and seems to improve theatre flow. With newer models using 3D stereoscopic vision, it could be further evaluated as a heads-up viewing system within extraocular and oculoplastic surgery.

The enlarged extraocular muscle: to relax, reflect or refer?

PurposeExtraocular muscle enlargement (EOME) is most commonly associated with thyroid eye disease, but there are other causes. We report our outcomes of investigating and managing non-thyroid-related EOME (NTR-EOME).MethodsRetrospective consecutive case series. Sixteen patients identified by clinical features and orbital imaging. Patient demographics, radiological features, and adjuvant tests including biopsy and final diagnosis were recorded.ResultsMean age at presentation 59.3 years (range 24-89 years). Mean follow-up 3.2 years (range 3 months to 5.5 years). Superior rectus (SR) was most commonly involved muscle (8/16 cases) followed by lateral rectus (4/16). Of the 16 cases, 14 were associated with underlying systemic neoplasia (5 lymphoma, 5 metastatic carcinoma, and 4 presumed paraneoplastic syndrome). All SR enlargement was associated with underlying neoplasia. All patients underwent orbital imaging followed by systemic imaging based on clinical index of suspicion (14/16 patients (13 full body CT (FBCT), 1 mammography)). Positive systemic radiological findings were detected in 12/14 cases. Of the remaining 2 patients, 1 underwent full body positron emission tomography-computed tomography (FBPET-CT), which detected thyroid carcinoma, and the second patient underwent FBCT for staging following orbital biopsy showing lymphoma. Four patients (25%) died within 3 years of follow-up due to disseminated systemic malignancy.ConclusionsAll cases of NTR-EOME should be viewed with a high level of clinical suspicion for systemic neoplasia, especially when the SR is involved. FBCT can help to identify a primary systemic cause. FBPET-CT is best reserved for cases negative on FBCT or for staging and monitoring systemic disease. NTR-EOME can be associated with significant mortality (25%), hence warrants prompt and thorough systemic investigation.

Eyelid-parotid metastasis: do we screen for coexisting masses? A case series.

OBJECTIVE: To report three cases illustrating that it is not unusual for a primary eyelid tumour to metastasise to the parotid gland and vice versa. CASE REPORTS: Two patients with malignant parotid tumours underwent radical parotidectomy and presented subsequently with eyelid lesions. Biopsy showed that both eyelid lesions were histologically similar to the primary parotid tumour. A third patient was noted to have ipsilateral upper eyelid and parotid gland tumours. Histology and immunocytochemistry were used to differentiate the primary tumour and the metastasis. CONCLUSION: These cases illustrate that tumours involving eyelids and parotid glands can present simultaneously or sequentially, and either of these structures could be the focus of primary or metastatic tumour. The important message for oculoplastic and parotid surgeons is to routinely assess both the periocular and parotid area when patients present with a mass in either structure.

Upper lid entropion post ptosis correction: is tarsal buckling the cause?

PURPOSE: To report two cases of the rare complication of entropion following involutional ptosis surgery and its successful management. METHODS: Clinical findings and management of the patients are presented. RESULTS: Case 1: An 89-year-old female underwent aponeurosis advancement surgery for left involutional ptosis. Post-operatively she achieved good lid height, but had developed entropion of the upper lid which resulted in a persistent corneal epithelial defect. The patient underwent repeat surgery during which the aponeurosis was found to be inserted into the lower part of middle one third of tarsus with the tarsus itself being extremely thin. The aponeurosis was reinserted into upper third of tarsus, followed by greyline split with anterior lamellar repositioning. Post-operatively the patient achieved good lid height with correction of the entropion.Case 2: A 70-year-old male who had previously undergone bilateral brow lift and ptosis correction two years ago, was referred with right upper lid entropion. During surgery the aponeurosis was found to be inserted into the lower part of middle one third of tarsus, with a very thin tarsus. This patient was also managed by reinserting aponeurosis into upper third of tarsus with grey line split and anterior lamellar repositioning following which he achieved good lid height and correction of the entropion. COMMENT: Entropion has rarely been reported as a complication of ptosis surgery. This case series highlights the importance of taking special care when advancing the aponeurosis, in cases where the tarsus is thin, as it may result in vertical buckling of the tarsus.

Drug-induced ectropion: what is best practice?

PURPOSE: To review cases of possible drug-induced ectropion and recommend what we consider to be best practice. DESIGN: Retrospective observational case series. PARTICIPANTS: Thirteen consecutive outpatients. METHODS: Records of 13 outpatients on topical medication presenting with topical drug-induced ectropion were retrospectively analyzed. MAIN OUTCOME MEASURES: Eyelid position, topical agent causing the allergy, and medical and surgical management options. RESULTS: In all 13 patients, the ectropion resolved partially or completely after discontinuing the offending topical agent. Dorzolamide (53%) was the most common offending agent, followed by brimonidine (23%). One of the 13 patients underwent failed ectropion surgery correction before referral, but improved once the topical agent was discontinued. Two of the patients successfully underwent surgical correction for ectropion after discontinuing their topical therapy. Those patients who discontinued the topical therapy and had a short course of steroid therapy did not require surgical correction. CONCLUSIONS: This study demonstrates that sensitivity to topical agents can induce ectropion in more than 1 manner. Chronic exposure to the causative agent leads to cicatricial changes in the anterior lamella of the eyelid in susceptible individuals, and can manifest as contact dermatitis leading to tissue edema and mechanical ectropion. Early recognition of this condition and discontinuation of therapy is of paramount importance; it may lead to complete resolution. Topical steroids are a necessary adjunct in the management of drug-induced ectropion. Based on our experience, we propose a management algorithm for drug-induced ectropion.

Obesity intervention among African-American children and adolescents.

Often, researchers and clinicians approach the African-American community from a deficit model with African Americans viewed as having less desirable health practices and higher disease risk; however, in developing interventions for African Americans, it is important to keep in mind positive aspects of black culture as they relate to obesity. For example, the cultural acceptance of a larger body type and less negative views toward overweight individuals need not be viewed as problematic or abnormal. In fact, it could be argued that majority culture has a dysfunctional view of body image and obesity. The fact that whites are less likely to be overweight than African Americans may stem from a value system that places undue emphasis on thinness, youth, and external beauty and a culture that imbues women with shame about how they look and what they eat. Thus, rather than holding whites and majority culture as the ideal, it may be important to incorporate the positive elements of black culture regarding body image and food rather than attempting to shift their values toward those of European Americans. How best to achieve a reduction in obesity and its medical consequences, without inducing undesirable shifts in body image and attitudes toward food, is a formidable but important challenge.

Spectrum of Head-Neck cancers at Allahabad.

A retrospective study of Head-Neck malignancy was conducted at Allahabad over a period of twenty two years from 1975 to 1996. During this period, 5,386 new Head-Neck Cancer cases were reported. Peak presentation of males was in sixth decade and in females it was in fifth decade of life. The sex ratio in this series was 3∶6∶1 while reverse sex ratio was observed in malignancies of thyroid, alveolus-gingiva, nasal cavity and post-cricoid region. Oral cavity lesion was the predominant cancer followed by larynx and oropharyngeal malignancy. Histologically, majority (89.97%) were squamous cell carcinoma with varied differentiation. Factors responsible for the high incidence of Head-Neck Cancers are discussed. An argent need is felt for the prevention and cessation strategies to achieve the goal of smoke free society by the year 2000 as expressed by Dr. Knoop so as to revert back the present trend of preventable Head-Neck Cancers.

Prevalence and correlates of preventive care among adults with diabetes in Kansas.

OBJECTIVE: To assess the prevalence and correlates of recommended preventive care among adults with diabetes in Kansas. RESEARCH DESIGN AND METHODS: A cross-sectional telephone survey was conducted among a sample of adults (> or = 18 years of age) with self-reported diabetes. Recommended preventive care was defined based on four criteria: number of health-care provider (HCP) visits per year (> or = 4 for insulin users and > or = 2 for nonusers), number of foot examinations per year (> or = 4 for insulin users and > or = 2 for nonusers), an annual dilated eye examination, and a blood pressure measurement in the past 6 months. RESULTS: The mean age of the 640 respondents was 61 years, 58% were women, and 86% were white. In the preceding year, 62% of respondents reported the appropriate number of visits to a HCP 27% the appropriate number of foot examinations, 65% an annual dilated eye examination, and 89% a blood pressure measurement in the preceding 6 months. Only 17% (95% CI 14-20) met all four criteria for recommended care. The adjusted odds of receiving recommended care were higher for males than for females (odds ratio [OR] 1.6; 95% CI 1.1-2.5), higher for people whose HCP scheduled follow-up appointments than for those who self-initiated follow-up (OR 2.7; 95% CI 1.6-4.8), and higher for former smokers than for current smokers (OR 3.1; 95% CI 1.6-6.9). CONCLUSIONS: Preventive care for people with diabetes is not being delivered in compliance with current guidelines, especially for women and current smokers. Scheduling follow-up visits for patients, targeting certain high-risk populations, and developing protocols to improve foot care may be effective in improving care.

Injury prevention practices as depicted in G-rated and PG-rated movies.

BACKGROUND: Previous studies on alcohol, tobacco, and violence suggest that children's behavior can be influenced by mass media; however, little is known about the effect of media on unintentional injuries, the leading cause of death among young persons in the United States. OBJECTIVE: To determine how injury prevention practices are depicted in G-rated (general audience) and PG-rated (parental guidance recommended) movies. DESIGN: Observational study. SETTING: The 25 movies with the highest domestic box-office grosses and a rating of G or PG for each year from 1995 through 1997. Movies that were predominantly animated or not set in the present day were excluded from analysis. SUBJECTS: Movie characters with speaking roles. MAIN OUTCOME MEASURES: Safety belt use by motor vehicle occupants, use of a crosswalk and looking both ways by pedestrians crossing a street, helmet use by bicyclists, personal flotation device use by boaters, and selected other injury prevention practices. RESULTS: Fifty nonanimated movies set in the present day were included in the study. A total of 753 person-scenes involving riding in a motor vehicle, crossing the street, bicycling, and boating were shown (median, 13.5 person-scenes per movie). Forty-two person-scenes (6%) involved falls or crashes, which resulted in 4 injuries and 2 deaths. Overall, 119 (27%) of 447 motor vehicle occupants wore safety belts, 20 (18%) of 109 pedestrians looked both ways before crossing the street and 25 (16%) of 160 used a crosswalk, 4 (6%) of 64 bicyclists wore helmets, and 14 (17%) of 82 boaters wore personal flotation devices. CONCLUSIONS: In scenes depicting everyday life in popular movies likely to be seen by children, characters were infrequently portrayed practicing recommended safe behaviors. The consequences of unsafe behaviors were rarely shown. The entertainment industry should improve its depiction of injury prevention practices in G-rated and PG-rated movies.
