We report an unusual presentation of an orbital spindle cell hemangioma in a 40-year-old male, who noted sudden redness and swelling of the left eye on waking up. On examination, the patient was found to have edema of upper eyelid edema, periorbital ecchymosis, and subconjunctival hemorrhage in the left eye at presentation. On treatment with topical medications, patient had transient symptomatic relief; however, he later developed blurring of vision. When seen 10 days later, the patient's left eye showed axial proptosis. Radiological investigations revealed an intraconal soft tissue mass in the left medial rectus. Emergency orbital decompression with mass excision was done; histopathological examination of the excised mass revealed spindle cell hemangioma. Postsurgery patient had complete restoration of vision. To our knowledge, an acute presentation of an orbital hemangioma with subconjunctival hemorrhage and periorbital ecchymosis, visual loss doesn't occur commonly; hence, such presentations have to be reviewed with care.

INTRODUCTION
Complicated rhinosinusitis is a rare but life-threatening pathology that requires both medical and surgical treatment as soon as possible. The spread of the infection from the paranasal sinuses affects, most often, the orbit, patients presenting diplopia, preseptal cellulitis, orbital cellulitis, or even blindness alongside exteriorization of puss from the middle meatus and nasal obstruction.
MATERIALS AND METHODS
We carried out a retrospective review of 32 patients that were diagnosed in our clinic with complicated rhinosinusitis from 2015 to 2022. All the patients received at least one intravenous antibiotic, and some also received antifungal drugs. All patients underwent surgery, either endoscopically or combined approach. Nasal washout or nasal swabs during surgery were sent for laboratory examination in all patients, and we studied the microbial etiology in these extensive infections. A database with all the information regarding demographic and medical data was established.
RESULTS
78% of the patients were male, with a mean age of 50.55. A wide range of antibiotics were used, while some patients, diagnosed with mucormycosis also received antifungal drugs. The mean hospitalization period was 12 days. We correlated the type of antibiotic with the hospitalization period and the outcome but also the degree of involvement of the orbit and the microbial strains identified.
DISCUSSION
The management of patients with complicated rhinosinusitis is complex and dynamic and it must be tailored to every patient, after an interdisciplinary meeting with the infectious disease specialist, ophthalmologist, and rhinologist. The microbial strains that produce such important infections are sometimes multi-resistant or combined, patients usually already had followed a course of antibiotics at home, and choosing the right treatment is sometimes challenging.

Graves' eye disease, also called Graves' orbitopathy (GO), is a potentially debilitating autoimmune disease associated with retro-orbital inflammation and tissue expansion, involving both fibroblasts and adipocytes, resulting in periorbital edema, worsening proptosis, and muscle dysfunction with diplopia and may ultimately threaten sight. Accumulating evidence has indicated that autoantibodies to the thyrotropin receptor (TSHR), which induce the hyperthyroidism of Graves' disease, also help mediate the pathogenesis of the eye disease in susceptible individuals through TSHR expression on retro-orbital cells. Since it has long been known that the effects of insulin-like growth factor 1 (IGF-1) and thyrotropin are additive, recent clinical trials with a human monoclonal IGF-1 receptor blocking antibody (teprotumumab; IGF-1R-B-monoclonal antibody [mAb]) have demonstrated its ability to induce significant reductions in proptosis, diplopia, and clinical activity scores in patients with GO. However, the molecular mechanisms by which such an antibody achieves this result is unclear. We have used Li-Cor In-Cell Western, Western blot, and immunohistochemistry to define levels of different proteins in mouse and human fibroblast cells. Proteomic array was also used to define pathway signaling molecules. Using CCK-8 and BrdU cell proliferation ELISA, we have analyzed proliferative response of these cells to different antibodies. We now show that a stimulating TSHR antibody was able to induce phosphorylation of the IGF-1R and initiate both TSHR and IGF-1R signaling in mouse and human fibroblasts. IGF-1R-B-mAb (1H7) inhibited all major IGF-1R signaling cascades and also reduced TSHR signaling. This resulted in the antibody-induced suppression of autophagy as shown by inhibition of multiple autophagy-related proteins (Beclin1, LC3a, LC3b, p62, and ULK1) and the induction of cell death by apoptosis as evidenced by activation of cleaved caspase 3, FADD, and caspase 8. Furthermore, this IGF-1R-blocking mAb suppressed serum-induced perkin and pink mitophagic proteins. Our observations clearly indicated that stimulating TSHR antibodies were able to enhance IGF-1R activity and contribute to retro-orbital cellular proliferation and inflammation. In contrast, an IGF-1R-B-mAb was capable of suppressing IGF-1R signaling leading to retro-orbital fibroblast/adipocyte death through the cell-extrinsic pathway of apoptosis. This is likely the major mechanism involved in proptosis reduction in patients with Graves' eye disease treated by IGF-1R inhibition.

Conjunctival provocation test (CPT) is used to demonstrate clinical relevance to a specific allergen. (Bt) is a prevalent allergen in tropical regions. Its major allergen is commonly detected in house dust in Brazil. Patients with allergic rhinoconjunctivitis (ARC) have IgE antibodies to Bt although it may not indicate clinical allergy. The purpose of this study is to demonstrate the role of CPT in clinical allergy to Bt in allergic conjunctivitis (AC). CPT was performed in asymptomatic subjects with ARC ( = 26) outside the grass pollen season. They had positive skin prick tests (SPT) to Bt and other common inhalant allergens and they were off topical or systemic antihistamines. Standardized allergens were used for CPT (Blo t 5 462.5 ng/mL in 1:1 solution, Alk Abelló). CPT was conducted on a control group of subjects ( = 29) without symptoms of ARC and with negative SPT. CPT was performed with progressive doses of allergen solutions in normal saline (1:32, 1:16, 1:8, 1:4, 1:2). CPT with the same allergen dose that elicited a positive reaction was repeated one week later. The protocol was approved by the local Ethics Board and signed informed consent was obtained from all participants. There were 92% (24/26) of positive CPT in subjects sensitized to Bt. Significant association was found between SPT and CPT results with Bt ( < 0.0001). CPT had 92% sensitivity and 100% specificity when compared to SPT results. Positive reactions with the same dose or one immediately higher occurred in 21 out of 22 subjects who repeated TPC 1 week later. Mild transient nasal symptoms (21/24) were the major side effects of positive CPT followed by moderate periorbital edema which occurred in 41% (10/24). One controlled asthmatic BT-sensitized subject developed wheezing and dyspnea during a positive CPT with Bt that cleared with inhaled albuterol (400 mcg). There were no reactions whatsoever of CPT in non-allergic subjects. This study demonstrated that Bt may cause allergic conjunctivitis in our population. In addition, CPT is a safe and reproducible test if standardized allergens are used.

The periocular region is challenging for cosmetic laser surgeons. Surgery and laser resurfacing have traditionally been used to correct periorbital lines and wrinkles. Although effective, the associated downtime with these methods has made many people reluctant to decide for such treatments. More recently, the non-ablative long-pulse 2940 nm Er:YAG laser is being used to improve the structure and function and hence the appearance of skin in the periorbital region. The objective of this study is to evaluate the safety and efficacy of long-pulse 2940 nm Er:YAG laser for non-ablative treatment of periorbital static wrinkles and skin laxity. This is a prospective analysis of 30 patients treated for periorbital rejuvenation using three sessions of non-ablative long-pulse Er:YAG laser over a 3-month period. All patients were assessed according to Fitzpatrick's classification of periorbital wrinkles to class I, II, or III and were treated with 2940 nm Er:YAG laser using a fluence of 3.75 J/cm, a repetition rate of 1.7-2 Hz, and with the SMOOTH™ pulse mode (250 ms). The treatment sessions were performed on each patient, 4 weeks apart. Patient improvement was assessed before each laser session as well as at 12 months after the final treatment. Blind photographic evaluations were performed by three independent physicians using unlabeled before and after photos arranged in non-chronological order. Reviewers were asked to determine the before and after photos. Patients were asked to answer a questionnaire measuring satisfaction 4 weeks after each session, and to report any adverse reactions. There was statistically and clinically significant improvement in the Fitzpatrick classification of the periorbital wrinkles. Blinded evaluators correctly identified the before and after photos in all cases. All patients reported mild edema and erythema, which persisted for 1 to 2 days, and superficial peeling of the skin for 4 to 6 days after each laser treatment. No long-term adverse effects were reported. The non-ablative long-pulse 2940 nm Er:YAG laser seems to be a safe and effective treatment for periocular rejuvenation with minimal and tolerable adverse reaction. The improvement attained from the laser sessions was persisting after 1 year denoting the long-term efficacy of the procedure.

BACKGROUND
Trichinellosis, caused by a parasitic nematode of the genus Trichinella, is a zoonosis that affects people worldwide. After ingesting raw meat containing Trichinella spp. larvae, patients show signs of myalgia, headaches, and facial and periorbital edema, and severe cases may die from myocarditis and heart failure. The molecular mechanisms of trichinellosis are unclear, and the sensitivity of the diagnostic methods used for this disease are unsatisfactory. Metabolomics is an excellent tool for studying disease progression and biomarkers; however, it has never been applied to trichinellosis. We aimed to elucidate the impacts of Trichinella infection on the host body and identify potential biomarkers using metabolomics.
METHODOLOGY/PRINCIPAL FINDINGS
Mice were infected with T. spiralis larvae, and sera were collected before and 2, 4, and 8 weeks after infection. Metabolites in the sera were extracted and identified using untargeted mass spectrometry. Metabolomic data were annotated via the XCMS online platform and analyzed with Metaboanalyst version 5.0. A total of 10,221 metabolomic features were identified, and the levels of 566, 330, and 418 features were significantly changed at 2-, 4-, and 8-weeks post-infection, respectively. The altered metabolites were used for further pathway analysis and biomarker selection. A major pathway affected by Trichinella infection was glycerophospholipid metabolism, and glycerophospholipids comprised the main metabolite class identified. Receiver operating characteristic revealed 244 molecules with diagnostic power for trichinellosis, with phosphatidylserines (PS) being the primary lipid class. Some lipid molecules, e.g., PS (18:0/19:0)[U] and PA (O-16:0/21:0), were not present in metabolome databases of humans and mice, thus they may have been secreted by the parasites.
CONCLUSIONS/SIGNIFICANCE
Our study highlighted glycerophospholipid metabolism as the major pathway affected by trichinellosis, hence glycerophospholipid species are potential markers of trichinellosis. The findings of this study represent the initial steps in biomarker discovery that may benefit future trichinellosis diagnosis.

Review
BACKGROUND
Uveal melanoma is the most common primary intraocular malignancy in adults, often resulting in painless vision loss. We report a case of necrotic uveal melanoma presenting with orbital inflammation mimicking orbital cellulitis and present a comprehensive review of the literature and tabulation of reported cases.
SUMMARY
Our review found 44 published reports of spontaneously necrotic uveal melanoma involving 55 patients. Of these reports, 26 patients (47%) presented with orbital cellulitis. Presenting symptoms of necrotic uveal melanoma with orbital cellulitis included proptosis (82.8%), pain (80.7%), vision loss (61.5%), and restricted extraocular movements (46.2%).
KEY MESSAGES
Uveal melanoma can rarely mimic orbital cellulitis. Autoinfarction and tumor necrosis causes secondary orbital inflammation. Intraocular malignancy must remain in the differential for patients with orbital inflammation and vision loss.

An elderly female presented to the emergency department with a right-sided facial droop and headache for two weeks. Investigations revealed poorly controlled diabetes, and the patient was found to be in diabetic ketoacidosis. Maxillofacial computed tomography (CT) demonstrated right postseptal cellulitis with concern for acute invasive fungal sinusitis. The patient was taken to the operating room for orbital surgical exploration and antrostomy. Surgical pathology revealed broad hyphae consistent with species, and the patient was diagnosed with mucormycosis. Because the patient was not clinically improving, further imaging was obtained, which showed a large right retroantral phlegmon extending into the cranial fossa and right cavernous sinus, and the patient subsequently underwent surgical debridement. The following postoperative day, the patient was stroke-alerted due to altered mental status and inability to follow commands. She was found to have a small embolic infarct. Due to the poor prognosis of the patient, she was discharged with hospice. Mucormycosis is more commonly found in immunocompromised patients, such as those with uncontrolled diabetes mellitus but very rarely does it involve the cranium. This disease process is very important to recognize early due to high morbidity and mortality rates and devastating outcomes.
