Review
Clozapine (CLZ) is the drug of choice for the treatment of resistant schizophrenia; however, its suitable use is limited by the complex adverse effects' profile. The best-described adverse effects in the literature are represented by agranulocytosis, myocarditis, sedation, weight gain, hypotension, and drooling; nevertheless, there are other known adverse effects that psychiatrists should readily recognize and manage. This review covers the "rare" and "very rare" known adverse effects of CLZ, which have been accurately described in literature. An extensive search on the basis of predefined criteria was made using CLZ and its combination with adverse effects as keywords in electronic databases. Data show the association between the use of CLZ and uncommon adverse effects, including ischemic colitis, paralytic ileus, hematemesis, gastroesophageal reflux disease, priapism, urinary incontinence, pityriasis rosea, intertriginous erythema, pulmonary thromboembolism, pseudo-pheochromocytoma, periorbital edema, and parotitis, which are influenced by other variables including age, early diagnosis, and previous/current pharmacological therapies. Some of these adverse effects, although unpredictable, are often manageable if promptly recognized and treated. Others are serious and potentially life-threatening. However, an adequate knowledge of the drug, clinical vigilance, and rapid intervention can drastically reduce the morbidity and mortality related to CLZ treatment.

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.

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.

PURPOSE
Orbital cellulitis is a serious condition with potentially severe complications. Treatment requires interdisciplinary care and early introduction of antimicrobial therapy. In our tertiary center, a team of pediatricians, pediatric ophthalmologists, and otorhinolaryngologists successfully participated in the management of pediatric periorbital/orbital cellulitis. This study aimed to demonstrate our interdisciplinary approach and to investigate clinical profile and management of pediatric periorbital/orbital cellulitis.
METHODS
A retrospective chart review was performed of all pediatric patients hospitalized for periorbital and orbital cellulitis in a tertiary hospital center from September 15, 2016, to March 15, 2020.
RESULTS
A total of 26 children-median age 2.7 years (range 0.5-12)-were treated during the study period. Disease presentation was unilateral, mainly during winter (n = 12) and autumn (n = 12), without ophthalmoplegia/proptosis. Seven patients had orbital cellulitis (Chandler classification of ≥III) and were older (6.5 years, P = 0.011) with sinusitis (P < 0.001), required surgery (P = 0.004), underwent longer antimicrobial treatment (13 days, P < 0.001), and had a longer length of hospital stay (13.43 days, P = 0.001). Orbital cellulitis occurred in a median of three days (range 1-12) of acute rhinosinusitis. Radiological survey was performed in 11 patients, whereas six patients were treated surgically. All intraoperatively collected cultures (sinus swabs) were positive, whereas Streptococcus pyogenes and Peptostreptococcus were isolated in five cases. All patients fully recovered. No recurrence was documented.
CONCLUSION
Sinusitis is associated with severe orbital cellulitis and surgical management. Orbital cellulitis occurred early in the course of acute rhinosinusitis, as a distinctive presentation of rhinosinusitis. Interdisciplinary care and early management are crucial in treatment of pediatric periorbital/orbital cellulitis.

OBJECTIVES
Preseptal cellulitis is an infection that affects the palpebra and the periorbital superficial tissue. This study is an evaluation of the clinical findings, treatment, and complications of patients hospitalized with preseptal cellulitis in a single clinic.
METHODS
The records of 29 patients with preseptal cellulitis who were hospitalized in the Şişli Hamidiye Etfal Education and Research Hospital Pediatric Infection Clinic between November 2012 and November 2017 were analyzed retrospectively.
RESULTS
Of the 29 cases, 34.5% (n=10) were female and 65.5% (n=19) were male. The mean age was 61.76±46.95 months, and the mean length of hospital stay was 4.03±2.04 days. Periorbital swelling (72.4%) was the most common cause of complaint at hospital admission, and periorbital hyperemia and edema were observed in 93.1% of the clinical findings. Nine (52.9%) of 17 cases with predisposing factors were sinusitis-related. A blood culture was obtained in 21 (72.4%) cases. Imaging methods were used in 9 (31%) cases to support the diagnosis. All of the patients received broad-spectrum intravenous antibiotic therapy during hospitalization. The mean duration of antibiotic use was 10.10±3.41 days, including after discharge. None of the patients developed complications related to preseptal cellulitis.
CONCLUSION
Preseptal cellulitis is a very common orbital infection, especially in childhood. Although it generally has a good prognosis, it can progress rapidly to the orbita and intracranial structures. An accurate clinical approach and rapid treatment can prevent the spread of infection and avoid serious complications.

INTRODUCTION
A masquerade syndrome is an atypical presentation of a neoplastic process that mimics an inflammatory condition. In this paper, we focus on orbital pseudocellulitis.
CASE SERIES
Our case series includes 5 retinoblastoma patients with orbital pseudocellulitis at presentation. In 3 patients the disease was bilateral, in 1 trilateral, and in 1 unilateral. The eyes with pseudocellulitis were enucleated, while the fellow eyes were treated conservatively, when affected. Four patients responded well to the therapy and showed remission of the tumor. The patient with trilateral retinoblastoma did not respond to therapy and died of disease.
DISCUSSION
Differential diagnosis with infectious orbital cellulitis is extremely important. Patients with orbital cellulitis present with fever, sinusitis, leukocytosis, and raised inflammatory markers, while ophthalmoscopic examination is negative and imaging studies show sinus involvement. On the contrary, patients with retinoblastoma do not show systemic inflammation, while ophthalmoscopic examination reveals leukocoria, buphthalmos, and an intraocular tumor mass associated with retinal detachment. Magnetic resonance imaging shows intralesional calcifications and soft tissue edema without sinus involvement. Histology confirms the diagnosis.
CONCLUSIONS
Medical history, physical examination, and imaging studies are crucial in the diagnosis of retinoblastoma-associated orbital pseudocellulitis. Retinoblastoma should be excluded in all patients with signs of pre-septal orbital cellulitis through fundoscopy and/or imaging studies.

A 72-year-old male patient was referred to our outpatient clinic with a painful left eye protrusion accompanied by marked conjunctival chemosis and external ophthalmoplegia being progressed despite topical and oral antibiotic therapy. He developed ocular symptoms 9 days after receiving his second SARS-CoV-2 vaccine (VeroCell). Of note, in previous history, 2 weeks after the first dose of the COVID-19 vaccine, he also developed a life-threatening laryngeal oedema treated at an emergency care unit. MRI of the orbit excluded pansinusitis as possible origin of the orbital cellulitis, and repeated COVID-19 antigen and antibody PCR tests were negative during his hospitalization. On the next day after his admittance, parenteral dexamethasone 250 mg/die treatment was commenced resulting in a quick and complete resolution of the symptoms. Due to the facts regarding this case, such as the temporal coincidence and the lack of respective comorbidity, there might be a causative relationship between the vaccination and the presented orbital cellulitis. To the best of our knowledge, this is the first report on orbital cellulitis as a possible ocular adverse event following COVID-19 vaccination.
