At-risk patient documentation and naloxone dispersal for a rural statewide EMS "Naloxone Leave Behind" program.

Objectives: For successful Naloxone Leave Behind (NLB) programs, Emergency Medical Services (EMS) must identify patients at-risk for opioid overdose. We describe the first year of Vermont's NLB program and report rates of EMS documentation of at-risk patients with subsequent distribution of NLB kits in the subgroup of those refusing transport to an emergency department (ED). Methods: This retrospective cohort review of all EMS encounters over 1 year compared on-scene EMS documented to retrospective chart reviewidentified at-risk patients eligible for NLB kit dispersal. EMS was educated to identify at-risk patients through statewide mandatory training modules. At-risk patients were identified by electronic chart review using the same training criteria. As per protocol, patients identified as at-risk by EMS who refuse ED transport are eligible for NLB. NLB-appropriate patients by retrospective chart review without NLB protocol use documentation by EMS were considered "missed." Results: Of 110,701 EMS encounters, 2507 (2.4%) were at-risk by chart review. Among these, 793 refused transport to an ED. In this chart-review at-risk non-transported group, EMS documented 407 (51.3%) patients as at-risk by documenting use of the NLB protocol. Of these 407, EMS provided 141 (34.6%) with NLB kits. Fifteen (3.7%) patients refused kits. There were 386 (48.7%) potentially "missed" opportunities for NLB dispersal. Conclusion: EMS documented 51.3% of patients eligible for NLB dispersal, with 34.6% receiving kits. There was no documentation for 48.7% of chart-review at-risk patients, suggesting "missed" distribution opportunities. This study highlights the need for improved EMS identification of at-risk patients, EMS documentation adherence, and NLB kit provision.

Richter Syndrome Presenting as Subcutaneous Nodules and a Dermal Plaque.

ABSTRACT: Richter syndrome (RS) describes a phenomenon in which a patient with chronic lymphocytic leukemia (CLL) develops an aggressive lymphoma, most commonly diffuse large B-cell lymphoma (DLBCL). Reports of cutaneous RS remain exceedingly rare. We report a 61-year-old woman with relapsed/refractory CLL presenting with several subcutaneous nodules on her arms and legs and a single dermal plaque on her abdomen. Skin biopsy revealed a diagnosis of DLBCL, ABC-type, and her clinical status rapidly deteriorated following diagnosis. We review the variety of clinical presentations of cutaneous RS, its association with CLL, risk factors for RS development in CLL patients, and the distinctive histopathologic and immunophenotypic features of DLBCL. We hope to highlight the importance of prompt skin biopsy in patients with CLL presenting with progressive skin lesions and increase awareness of this aggressive clinical syndrome.

Evaluating the Effectiveness of Lacrimal Gland Botulinum Toxin Using the TEARS Score.

PURPOSE: Botulinum toxin (BoNTA) lacrimal gland injections are one treatment option for managing epiphora. Outcomes for epiphora in existing studies are subjective and lack grading. This study utilized validated grading instruments to evaluate the efficacy of BoNTA lacrimal gland injections. METHODS: Prospective study evaluating the TEARS score and quality of life in patients receiving incobotulinum toxin (Xeomin) lacrimal gland injections for epiphora. Epiphora was graded using the TEARS score. Quality of life was evaluated using the watery eye quality of life score. Etiology, benefit duration, complications and additional injections were recorded. RESULTS: Of the 28 patients, (median age 67.5 years), 19 (68%) had facial palsy gustatory epiphora (GE). Median effect duration was 13 weeks. Improvements in tearing frequency (T), clinical effects (E), and activity limitation (A) were seen in 57%, 57%, and 71% of patients, respectively. Median watery eye quality of life score improved from 42.4/100 ± 10.1 to 10.6 ± 15.5 (p < 0.001). Alongside crocodile tears, reflex tearing R-scores improved in 68% of patients with GE vs. 11% with non-GE causes (p = 0.004618). In total 89% of patients with GE and 56% with non-GE requested repeat injections. Self-reported percentage improvement ranged from 0% to 100% (median 60%, interquartile range 10%-76.25%). CONCLUSIONS: This is the first study reporting the outcomes of BoNTA lacrimal gland injections using validated TEARS and watery eye quality of life scores. Clinical and quality of life improvements are seen in most patients. Patients with GE achieve an additional improvement in dry eye-related reflex tearing alongside crocodile tears which both improve with BoNTA. TEARS data supports using BoNTA in these patients and is a useful validated grading instrument for epiphora.

Lower eyelid lengthening in facial nerve palsy: when is a periosteal flap required?

BACKGROUND/AIMS: To present a case series of patients with facial nerve palsy (FNP) undergoing lower eyelid surgery where inadequate horizontal tarsal length was encountered and managed with a periosteal flap. METHODS: A two-centre retrospective, non-comparative case series of all patients with FNP who underwent lower eyelid periosteal flap procedures. Theatre records identified all such procedures performed by, or under the supervision of, one of two surgeons (RM, BCP) between November 2018 and November 2020. Outcome measures, including the Cornea, static Asymmetry, Dynamic function, Synkinesis grading score, were measured preoperatively and postoperatively. RESULTS: All 17 patients had undergone medial canthal tendon (MCT) plication. Six had previously undergone MCT plication then were listed for further lower eyelid surgery. In 11 cases, horizontal deficiency was encountered intraoperatively, immediately following MCT plication. Four patients were surgery-naïve. 94% were within the 'contraction phase' of FNP (ie, greater than 1-year duration); eight (45%) had previously undergone lower eyelid shortening procedures (such as lateral tarsal strip procedure, LTS). All patients had improved lower eyelid position postoperatively, although at 1-year postoperation, four patients require redo lower eyelid surgery. CONCLUSIONS: MCT plication and stabilisation appear to be closely linked to the need for lower eyelid lengthening procedures, particularly in patients who have also undergone LTS and/or those within the 'contraction phase' of FNP. Unnecessary loss of horizontal tarsal length (particularly during LTS procedures) must be avoided in patients with FNP. Surgeons managing such patients should take care to identify inadvertent eyelid shortening early and be prepared to perform a lateral periosteal flap when required.

Perifolliculitis mimicking basal cell carcinoma.

We present a case of a periocular painless perifolliculitis clinically mimicking basal cell carcinoma (BCC), excised by margin-controlled excision. This case reminds readers that perifolliculitis as a response to rosacea can mimic BCC. The value of diagnostic biopsy and dermoscopy to support management planning and avoid unnecessary surgery is discussed.

Oral nicotinamide for non-melanoma skin cancers: A review.

There has been much interest in the role of oral nicotinamide supplementation in reducing the incidence of non-melanoma skin cancers. This article reviews the hypothesised mechanisms of action of nicotinamide, and the available literature outlining its role for this purpose. There have been five randomised controlled trials (RCT), one histopathological study and two case series exploring the effect of oral nicotinamide supplementation on UV-induced immunosuppression of the skin, and incidence of actinic keratoses and non-melanoma skin cancers (NMSC). The largest RCT received criticism of the statistical analyses used, but the critics still acknowledged a likely benefit of treatment with oral nicotinamide in reducing the incidence of NMSC. Nicotinamide has a favourable safety profile. Current evidence is not definitive that oral nicotinamide supplementation reduces the incidence of NMSC, but it constitutes a low-risk management option that may be particularly relevant for high-risk individuals, and should be discussed as an option for these patients.

The Importance of Identifying Meibomian Gland Inversion in Patients With Floppy Eyelid Syndrome.

BACKGROUND: Floppy eyelid syndrome (FES) is a common and underdiagnosed condition characterized by eyelid hyperlaxity with reactive palpebral conjunctivitis that can cause ocular irritation. It may be associated with meibomian gland dysfunction (MGD) and secondary tarsal curling, resulting in upper eyelid meibomian gland inversion (MGI) in the absence of obvious marginal entropion. PURPOSE: To highlight the possible significance of MGI in patients with FES and report findings and outcomes in patients with concomitant MGI and FES undergoing correction of MGI with or without upper eyelid horizontal tightening. METHODS: Retrospective, 5-year, noncomparative, single-center study of patients with FES and MGI, treated with MGI correction, with or without upper eyelid horizontal tightening, under the supervision of a single surgeon. Preoperative symptoms, surgical outcomes, complication rates, and postoperative symptoms were recorded. RESULTS: A total of 13 eyes of 9 patients were treated with MGI surgery over the study period. Seven were male. Mean age at the surgery was 63 (range 42-81) years. Two OSs, 3 ODs, and 4 OUs were treated. All patients were "cotton-tip test" positive, and 77% (10/13) had MGI-related superior corneal fluorescein staining. Three patients (33%) had previous standard tightening procedures with recurrence of symptoms within 5 to 24 (mean 16) months. Repeat horizontal tightening had been considered in all these cases before referral to our unit. Mean follow-up was 20 months. Eight patients (88.9%) had improvement of symptoms (n = 3, full resolution; n = 5, partial resolution). All patients demonstrated restoration of the normal anatomical position of the meibomian glands. Superior punctate staining resolved in all eyes. CONCLUSION: This study provides a proof of concept that upper eyelid MGI can be present and symptomatic in patients with FES. It may help explain cases where symptoms persist or recur early following standard upper eyelid horizontal tightening. Where superior corneal punctate staining and a positive cotton-tip test exist, surgical correction of MGI, alongside horizontal tightening, may provide better, and longer-lasting symptomatic relief. This study provides evidence for the need for a prospective study to evaluate the contribution of MGI in patients with FES.

Bringing Eyelid Surgery in Line with International Guidelines Regarding Peri-Operative Antibiotic Agents: A Pilot Study.

Background: International guidelines advise against prophylactic antimicrobial agents for primarily closed surgical incisions, but most oculoplastic surgeons report using chloramphenicol ointment. We evaluated baseline surgical site infection (SSI) rates in patients undergoing eyelid surgery who received prophylactic chloramphenicol ointment post-operatively. Withdrawal of prophylaxis was then prospectively audited to establish whether infection rates changed in a clinically meaningful way. This article reports the early findings. Patients and Methods: A single-center retrospective audit was undertaken; electronic medical records were reviewed for consecutive patients who underwent eyelid surgery with primary incision closure. All patients received post-operative prophylactic chloramphenicol. Those with histopathologic evidence of malignancy were excluded. Patient demographics, surgical details, evidence of post-operative SSI and other complications were recorded. Local policy was changed in accordance with national guidelines; prophylactic chloramphenicol ointment was withheld, and the above information collected prospectively. Our policy excluded skin malignancies, full thickness skin grafts, patients on systemic immunosuppression, and diabetes mellitus because of potential increased infection risk. Results: There were no statistically significant differences between the groups, except seniority of surgeon. Surgical site infection was identified in 14 of 872 eyes (1.6%) receiving post-operative chloramphenicol, and three of 133 eyes (2.25%) without antibiotic agents, which was not statistically significant. Conclusions: Post-operative SSI rates in eyelid surgery are low. Routine use of prophylactic antibiotic agents in primarily closed surgical eyelid incisions does not adhere to international standards and may contribute to antimicrobial resistance. Early results suggest infection rates remain low without prophylactic chloramphenicol; clinicians should consider withdrawing it from routine practice in suitable patients.

Bacteriostatic preserved saline for pain-free periocular injections: review.

We review evidence regarding the use of 0.9% benzyl alcohol in 0.9% sodium chloride solution for periocular injections ('preserved saline') including botulinum toxin A injections and local anaesthesia. A literature search was undertaken using search terms 'bacteriostatic saline', 'benzyl-alcohol saline', 'benzyl alcohol sodium chloride' and 'preserved saline'. Bibliographies identified further sources. There have been 62 studies published on the subject of preserved-saline since 1928. Significantly lower injection-associated pain levels for periocular/facial botulinum toxin injections reconstituted with preserved-saline rather than preservative-free saline are reported by 5 studies. Significantly lower injection-associated pain with preserved-saline diluted lidocaine and epinephrine solution for eyelid anaesthesia compared with unmodified or buffered lidocaine with epinephrine, and adequate anaesthesia, was reported by one study. Thirty-one studies have explored preserved-saline for anaesthetic and seven for bacteriostatic properties, with very low infection rates after periocular botulinum toxin injections, and reduced rates of infection in indwelling catheters when preserved saline is used to flush. A meta-analysis concluded that lidocaine-containing solutions are more effective at reducing pain from insertion of intravenous catheters. Patient-perceived pain related to periorbital injections of local anaesthesia is reduced when the anaesthetic is diluted with benzyl alcohol-preserved saline compared with other dilution or buffering options. Pain is similarly reduced for periocular botulinum toxin injections reconstituted with preserved saline compared with unpreserved saline. Benzyl-alcohol preserved-saline is inexpensive but costlier than unpreserved-saline, with minimal reported complications, particularly with periocular administration, and offers the opportunity to improve the patient experience.

Fusobacterium necrophorum-induced orbital cellulitis with intracranial involvement: a case report and review of the literature.

We report a case of a 17-year-old female who presented with orbital cellulitis and meningeal involvement secondary to severe paranasal sinusitis with positive blood culture for Fusobacterium necrophorum. The patient recovered after a 2-month course of systemic antibiotics and functional endoscopic sinus surgery.Fusobacterium necrophorum-induced orbital cellulitis is a rare entity, with only 5 previous cases reported in the literature, which are reviewed here as well. This review reveals that Fusobacterium necrophorum is an aggressive pathogen in orbital cellulitis and therefore we suggest that affected patients may require a correspondingly aggressive medical management. Furthermore, we advise additional workup to rule out Lemierre's syndrome, a severe complication of Fusobacterium necrophorum infection, including transthoracic echocardiogram, chest radiograph, upper extremities' venous duplex and magnetic resonance venography.

Bilateral Paraneoplastic Orbital Myositis Associated With Malignant Melanoma and Multiple Myeloma.

Paraneoplastic extraocular muscle enlargement has been reported in a small number of patients with cancers including breast or lymphoma, usually presenting with bilateral multiple muscle involvement. Such myositis may be autoimmune. Furthermore, orbital inflammation is a recognized complication of immune-modulation therapy used to treat melanoma, such as ipilimumab. Extraorbital myositis has been described in myeloma, and polymyositis in melanoma. We present a case of bilateral, asymmetrical extraocular muscle enlargement with spontaneous resolution in a patient with simultaneous new diagnoses of metastatic malignant melanoma and multiple myeloma. A similar episode 7 months before diagnosis also resolved spontaneously. The authors believe this to be the first reported case of paraneoplastic orbital myositis associated with multiple myeloma or untreated malignant melanoma.

Lymphoma and inflammatory disorders presenting in the orbit- a comparison of characteristics from a 10-year series in a tertiary hospital.

BACKGROUND/AIMS: To explore differences in clinical presentations and outcomes between patients with biopsy-proven orbital lymphoma and orbital inflammatory disease. METHODS: Clinical records of all patients who underwent orbital biopsy at Bristol Eye Hospital during a 10-year period were reviewed. Comparisons were made between patients diagnosed with orbital lymphoma and orbital inflammatory disease (OID). RESULTS: 35 patients were diagnosed with orbital lymphoma, undergoing 40 biopsies over the 10-year period studied. 62 patients had OID, undergoing 66 biopsies. Sub-analysis identified six patients with sarcoidosis, four with granulomatosis polyangiitis (GPA), eight with IgG4-related orbital disease, and 44 with idiopathic orbital inflammation (IOI). Patients with sarcoidosis and IOI were statistically younger at presentation than those with lymphoma, with means of 44 and 52 years, respectively, compared with 71 years. Lid swelling/puffiness was more common in OID than lymphoma. More patients with lymphoma lost vision during follow-up than those with OID. CONCLUSIONS: Although younger age of presentation and presence of lid swelling are more likely to indicate orbital inflammation than orbital lymphoma, orbital biopsy remains the gold standard to distinguish these two entities. In the case of orbital inflammation, identification of a specific diagnosis allows appropriate ongoing referral and investigations for potential systemic involvement and helps guide immunosuppressive treatment.

Anterior approach ptosis surgery: comparison of absorbable polyglactin sutures and non-absorbable polyester sutures. Does Vicryl stand the test of time?

PURPOSE: To determine whether the long-term success of ptosis surgery is influenced by the use of absorbable or non-absorbable sutures to advance the levator aponeurosis onto the tarsal plate. METHODS: Multi-centre retrospective comparative study of re-operation rates in primary anterior approach ptosis surgery using absorbable polyglactin sutures (Vicryl) and non-absorbable polyester sutures (Ethibond). The Medisoft audit tool was used to identify all patients who underwent primary ptosis surgery for aponeurotic ptosis, performed by five oculoplastic consultants within a 7-year period, across two NHS Ophthalmology departments. The electronic patient records were reviewed for each patient. Basic demographics, suture material, and post-operative complications were recorded. All patients requiring repeat surgery between the study dates and the present day were recorded, allowing a minimum postoperative period of 3 years and 10 months. Re-operation rates in surgery using absorbable Vicryl sutures and non-absorbable Ethibond sutures were compared using Fisher's exact test. RESULTS: Four hundred and fifty-five operations in 330 patients were performed within the study period that met the inclusion and exclusion criteria. Fifty-seven percent of the patients were female, with an average age of 68.8 years. One hundred and sixty-nine operations in 128 patients were performed using absorbable Vicryl sutures. Of these, 22 (13.0%) required repeat operations. Two hundred and eighty-six operations in 202 patients were performed using non-absorbable Ethibond sutures. Of these, 17 (5.9%) required repeat operations. The two-tailed P-value was 0.0143. CONCLUSION: The use of non-absorbable Ethibond sutures to advance the levator aponeurosis onto the tarsal plate in primary ptosis surgery is associated with improved long-term success and reduced need for secondary surgery.

Multi-disciplinary team meetings with specialist radiologists may improve pre-operative clinico-radiological diagnostic accuracy in patients requiring orbital biopsy and offer reciprocal educational opportunities.

BACKGROUND: Accurate pre-operative diagnosis of orbital lesions supports appropriate prioritisation of patients into available theatre time. We examine the accuracy of pre-operative clinico-radiological diagnosis in a tertiary centre with weekly dedicated orbital clinics and associated multi-disciplinary team meetings. METHODS: A retrospective case notes review was undertaken for all patients who had an orbital biopsy performed at Bristol Eye Hospital between 2007 and 2017. In this centre, pre-operative clinico-radiological differential diagnoses are discussed during multi-disciplinary team meetings including two orbital specialist ophthalmologists and a specialist neuro-radiologist. Clinico-radiological diagnoses were compared with histopathological outcomes. Subcategory analysis according to histopathological diagnosis was undertaken to look for trends. RESULTS: 172 biopsies were taken from 156 patients, median age 59 years (range 3 months to 91 years). 60.9% of patient were females, with equal numbers of right and left-sided biopsies. 11 patients had inconclusive histopathology. 15 patients did not have a documented preoperative diagnosis or differential offered in available notes. 71 patients (49.0%) demonstrated an exact match between clinico-radiological and histopathological diagnosis, 93 (64.1%) demonstrated a category match (e.g. inflammatory, lymphoproliferative) and for 111 (76.6%), the histopathological diagnosis was considered within the list of proffered clinico-radiological differential diagnoses. CONCLUSIONS: Accuracy of pre-operative diagnosis of orbital lesions undergoing biopsy was higher in our series than previously reported by Koukoulli et al. Specialist head and neck radiology input via regular orbital multi-disciplinary meetings might be reciprocally educational and explain this difference. The authors recommend all surgeons who perform orbital surgery should have access to such multi-disciplinary meetings.
