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.

Sensory Changes in Periocular Skin After Upper Eyelid Surgery.

The aim of this interventional, prospective study is to estimate the change in periocular cutaneous sensation after upper eyelid surgery. The trial included 48 eyes of 24 patients undergoing upper eyelid blepharoplasty or upper eyelid blepharoplasty and blepharoptosis repair. Eyelid sensation was measured using a Cochet-Bonnet filament-type esthesiometer at 4 predetermined anatomical locations in the upper eyelid. The mean esthesiometry reading was calculated at the preoperative visit (4.06 cm), at 2-week postoperative visit (4.38 cm), and at final postoperative visit (4.52 cm). Paired t test showed no significant difference in sensation measurement at second visit compared with baseline (P = 0.205) or at final visit compared with baseline (P = 0.092). Paired t test showed no correlation between type of surgery and change in sensation. Sex and age did not influence change in sensation. In 40 of 42 eyelids, (95.24%), patients reported no reduction in subjective eyelid sensation. The authors conclude that eyelid sensation was not compromised objectively or subjectively by upper eyelid skin incision surgery. Surgeons can reassure patients contemplating surgery that it is very unlikely that cutaneous sensation will be damaged.

Kelly punch punctoplasty vs. simple punctal dilation, both with mini-monoka silicone stent intubation, for punctal stenosis related epiphora.

OBJECTIVES: To compare the outcomes of stenotic punctal dilation by means of a punctal dilator alone vs. a Kelly punch punctoplasty, both followed by insertion of a mini-monoka stent, for treatment of symptomatic punctal stenosis. METHODS: A retrospective, comparative study. The participants were patients with punctal stenosis related epiphora treated at the Goldschleger Eye Institute, Sheba Medical Center. All patients were treated either by simple punctal dilation (group 1) or Kelly punch-assisted punctoplasty (group 2), both followed by mini-monoka stent insertion. Symptoms relief and subjective epiphora scoring (Munk score) were compared and analysed. RESULTS: Fifty patients were included in the study; Mean age (+SD) of the participants was 60 years (±12, range 30-86 years). Baseline characteristics (age, gender distribution, and visual acuity) were similar in both groups. The mini-monoka stent was placed for an average period of 2 weeks, and all patients received postoperative steroids and antibiotic treatment for 1 week. The Munk score decreased significantly in both groups following the procedure, dropping from 4.9 to 1.9 in group 1 and from 4.3 to 1.2 in group 2 (P < 0.005 for both groups). There was no difference in the delta Munk score between the two groups. CONCLUSIONS: Simple punctal dilation followed by insertion of a mini-monoka stent is effective in alleviating the symptoms of punctal stenosis-related epiphora. There was no added benefit when the more invasive Kelly punch-assisted punctoplasty was used, raising some doubt about its justification in these cases.

No impact of nasal septoplasty on the outcome of endoscopic dacryocystorhinostomy.

OBJECTIVE: To compare the outcomes of combined endoscopic dacryocystorhinostomy (endoDCR) with nasal septoplasty for deviation of the nasal septum to endoDCR alone in cases of nasolacrimal duct obstruction (NLDO). METHODS: A retrospective cohort study that included 107 consecutive patients with NLDO, who underwent endoDCR with or without concomitant nasal septoplasty in our institution between October 2009 and October 2017. RESULTS: A total of 117 operations were performed (107 patients, 80.4% females; mean age ± SD 51.1 ± 19.5 years). Twenty-five (21.4%) endoscopic surgeries were combined with septoplasty (the endoDCR + septoplasty group), and 92 (78.6%) comprised endoDCR alone (the endoDCR group). There was no difference in anatomical success and functional success rates between the two groups (P = 0.76 and P = 0.18, respectively). There were no complications attributed to the septoplasty component of the surgical procedure. CONCLUSION: Considerable numbers of patients undergoing endoDCR also require a septoplasty. Combining an additional procedure (septoplasty), that was not performed for its original indication but rather for facilitating the main surgical intervention (endoDCR), yields surgical success and associated complications equivalent to those of endoDCR alone.

Endoscopic dacryocystorhinostomy with and without mucosal flap-is there any difference?

BACKGROUND: The nasal mucosa is sacrificed in conventional endoscopic dacryocystorhinostomies (EDCRs). Some surgeons, however, modify the technique by elevating a mucosal flap prior to creating the osteotomy with the aim of preserving the mucosa. To our knowledge, no clear-cut benefit of a mucosal flap has been established. The aim of this study is to examine the differences in surgical techniques and success rates of EDCRs with and without mucosal flap preservation. METHODS: We carried out a medical record review of all patients who underwent primary EDCR at the Goldschleger Eye Institute from October 2009 to October 2017. The following data were retrieved from the medical database and analyzed: patient demographics (age at diagnosis and gender), medical history, examination findings, surgical details, postoperative success, complications, and follow-up. RESULTS: A total of 107 patients who underwent 117 EDCRs participated in the study. Fifty-one patients comprised the group without a mucosal flap and 56 patients comprised the group with mucosal flap preservation. The medical history, presenting complaints, and preoperative examination findings were similar for both groups. The surgical success rate was not significantly different between the groups (82.1% without flap vs. 86.8% with flap, P = 0.478, Chi-square). CONCLUSION: The findings of this comparison of EDCRs with and without mucosal flap preservation in a large patient population revealed no differences in surgical success or complications rates between the two procedures and, therefore, no benefit for adding flap preservation to conventional EDCRs.

An experimental treatment of ocular quinine toxicity with high-dose 9-cis Beta-carotene.

PURPOSE: To report a case of severe ocular quinine toxicity after a suicide attempt and an experimental treatment with high-dose 9-cis beta-carotene. METHODS: Interventional case report. RESULTS: A 59-year-old woman presented with acute bilateral blindness after ingesting high dose (12 g) of quinine sulphate. Her vision was no light perception in either eye, and her pupils were fixed and middilated. Because of limited vision and poor prognosis, she was treated with an experimental rescue therapy of high-dose 9-cis beta-carotene Dunaliella bardawil powder for 3 months, starting 10 days postingestion. Electroretinography measurements showed transient improvement in a-wave amplitudes. The electroretinography b-wave showed only partial transient improvement in the left eye. Overall, the patient's visual acuity improved to 20/33 in the right eye and 20/40 in the left eye, but with extremely constricted visual fields. CONCLUSION: Transient improvement in electroretinography measurements was observed under treatment with high-dose 9-cis beta-carotene in ocular quinine toxicity, although no clinical benefit was documented. More research is needed to determine its effect in patients with toxic retinal damage.

Müller's muscle-conjunctival resection for upper eyelid ptosis: correlation between amount of resected tissue and outcome.

AIMS: To explore the relationship between the amount of resected Müller's muscle-conjunctiva (MMCR) and clinical outcome in patients undergoing upper eyelid ptosis surgery. METHODS: 49 patients underwent 87 MMCR surgeries. The total areas of the specimen and of MM were measured in pixels. RESULTS: The average percentage of muscle tissue in relation to total excised tissue was 21%. Intraoperative MMC tissue measurements and postoperative improvement in eyelid position (delta marginal reflex distance 1 (MRD1)) were positively correlated (R=0.427, p=0.09). There was a weak correlation between total areas measured on the histological slides and the intraoperative MMCR values (R=0.3, p=0.057). Total histological areas did not correlate with the delta change in eyelid position or with the amount and percentage of resected muscle tissue and the extent of improvement in eyelid position (delta MRD1) or final eyelid position (postoperative MRD1). CONCLUSIONS: Post-MMCR improvement in eyelid positions did not correlate with the percentage of MM in the excised tissue. We believe that the mechanism responsible for surgical outcome is plication or scarring of the posterior lamella and not the amount of resected MM. More lift in eyelid position can be anticipated when more tissue is excised by MMCR, and not when more muscle is excised.
