Aeromonas hydrophila orbital cellulitis as post cesarean sepsis-An unthinkable eye opener

Peripartum orbital cellulitis and pan ophthalmitis are rare complications. Here we report one such case and the need for aggressive management of postpartum infections especially post cesarean.

Visual outcomes following orbital decompression for orbital infections

OBJECTIVE

To analyze the visual outcomes and sequelae of endonasal intervention for orbital infections.

INTRODUCTION

Orbital infections pose a serious threat to vision in the pediatric population and can result in complications such as blindness, diplopia, intracranial involvement, and death. [1] Orbital decompression by endonasal intervention is a common treatment to address a variety of orbital infections including orbital cellulitis, orbital abscesses, and subperiosteal abscesses. [2] The outcomes of visual sequelae such as loss or limitation of visual acuity, extraocular movements, and increased intraocular pressure following orbital decompression via endonasal intervention have not been sufficiently investigated in the current literature.

METHODS

This retrospective cohort study was performed at our tertiary care pediatric hospital using data from 69 patients aged 0-18 years who were admitted between 2008 and 2018. Data was extracted from the electronic medical record system.

RESULTS

Following endoscopic sinus surgery, symptoms of orbital infection improved throughout the cohort. Improvement in visual acuity is demonstrated by a statistically significant decrease in the average logMAR value in both the right and left eye (P = 0.002 and P = 0.028 respectively). There was also a significant improvement to normal values postoperatively for patients who initially presented with abnormal tonometry, extraocular movement, and the appearance of eyelids and eyelashes.

CONCLUSION

There is no decline or loss of vision with otolaryngology surgical intervention for orbital cellulitis in our cohort. This retrospective chart review demonstrates the efficacy of surgical intervention on overall visual outcomes following endonasal intervention for orbital infections such as orbital cellulitis, orbital abscesses, and subperiosteal abscesses.

Role of Acute Rhinosinusitis in Periorbital Infections in Children

OBJECTIVE

Periorbital cellulitis in children are commonly caused by acute rhinosinusitis (ARS). This study investigated the association of ARS and the severity of periorbital cellulitis in children.

STUDY DESIGN

Retrospective case-control study of children with periorbital cellulitis with ARS versus periorbital cellulitis without ARS.

SETTING

Patients were seen at West Virginia University Children's Hospitals between August 2011 to August 2022.

METHODS

Patients were divided into cases and controls based on presence or absence of ARS. ARS was defined based on clinical symptoms with objective presence of disease on CT scan. Patients' characteristics, treatment, hospital length of stay, and readmission were collected.

RESULTS

The sample consisted of 118 pediatric patients with orbital cellulitis. Patients with ARS were younger than patients without ARS (6.3 vs 8.5, p = 0.025), however there were no sex differences between two groups (p = 0.540). The ARS group had higher incidence of postseptal cellulitis (51.5% vs 9.6%, p < 0.001). As compared to patients without ARS, patients with ARS were more likely to be admitted (p < 0.001), have a longer length of stay (median of 3.5 days vs 0.5 days, p < 0.001), require IV antibiotics (95.3% vs 54.9%, p < 0.001), and require surgical intervention (23.1% vs 5.8%, p < 0.001). Readmission rate was similar between the two groups.

CONCLUSION

Children presenting with acute periorbital cellulitis who have ARS tend to have more severe infection requiring higher level of care. ARS should be assessed and incorporated into the plan of care of pediatric patients with periorbital infections.

Orbital Abscess Secondary to Nasolacrimal Duct Obstruction in an Extremely Preterm Infant

Orbital abscesses are rarely encountered in children younger than 1 year. The literature is limited to isolated case reports and a few case series. Most such cases are reported in infants born at term, with the earliest reported gestational birth age at 34 weeks. Children are more prone to orbital cellulitis compared with adults due to their underdeveloped sinuses and immature immune systems, and the origin is most commonly an ethmoid sinus infection. Orbital cellulitis secondary to dacryocystitis is even less common, with only a few isolated cases reported in infants and children. Herein, the authors present a case of a large extraconal and intraconal orbital abscess secondary to nasolacrimal duct obstruction and dacryocystitis in an extremely preterm infant. We discuss the diagnosis and multidisciplinary management of this challenging case.

Management of oculo-orbital complications of odontogenic sinusitis in adults

Introduction: Odontogenic maxillary sinusitis (OMS) is an infectious inflammatory pathology caused by a dental condition. Considering the anatomical relations with the orbit, maxillary sinus infection can easily spread, evolving into severe oculo-orbital complications that can sometimes be life-threatening. Material and methods: We performed a retrospective study of over 2 years, examining the data of 18 patients diagnosed with OMS with oculo-orbital complications. The patients were evaluated regarding their dental history, symptoms, clinical and endoscopic findings, ophthalmologic evaluation, bacteriologic tests, computed tomography (CT) imaging, medical and surgical treatment, and outcomes. Results: The age of the patients was between 24 and 65 years old with an almost equal gender distribution: 10 female and 8 male patients. From the total, 7 patients had type II diabetes, 2 of whom were insulin-dependent, 1 patient had thrombophilia and 2 patients had renal failure with peritoneal dialysis. Regarding the type of oculo-orbital complications, 10 patients were diagnosed with preseptal cellulitis and 8 with orbital cellulitis. Just 5 patients with orbital cellulitis required surgical treatment and orbitotomy was performed, followed by endonasal endoscopic drainage. The evolution after surgical treatment was favorable for all operated patients. Discussions: Oculo-orbital complications of OMS are typically more severe than those of rhinogenic sinusitis because anaerobic bacteria are involved. Immunosuppression represents a favorable environment for the development of OMS and its complications, diabetes being the most common risk factor. A negative prognostic feature is the appearance of ophthalmological symptoms in both eyes, so visual function may be reduced. The treatment of oculo-orbital complications of OMS is urgent and depends on a broad-spectrum antibiotic therapy associated or not with surgical intervention. Conclusions: The diagnosis of oculo-orbital complications of OMS is complex and requires clinical experience as well as extensive medical knowledge to treat both the cause and the consequences of the conditions quickly and effectively. The proper management of oculo-orbital complications is based on a multidisciplinary team: ophthalmology, ENT, dentistry, imaging, and laboratory. Abbreviations: OMS = odontogenic maxillary sinusitis, CT = computed tomography, ENT = ear-nose-throat, MRI = magnetic resonance imaging, HNS = head and neck surgery.

Non-visual complications of orbital cellulitis (NVCOC) in pediatric vs adult populations

PURPOSE

There have been many publications evaluating the visual outcomes of patients treated for orbital cellulitis. The aim of this study was to evaluate non-visual complications of post-septal orbital cellulitis (NVCOC) present 30 days after discharge from index hospitalization.

METHODS

This was an IRB-approved, retrospective chart review.

RESULTS

Ninety patients (45 pediatric, 45 adults) were identified with OC. NVCOC were significantly more common in adult patients as compared to children (40.0% vs 15.6% respectively; p < 0.05). The most common NVCOC among children was persistent ptosis, while clinically significant scarring was most common in adults. NVCOC were less persistent in children as compared to adults with 71.4% of complications in children resolving spontaneously by 6 month follow up as compared to 11.1% adults. (p < 0.05). The only statistically significant risk factor identified for the development of NVCOC in children and adults was the presence of ICE (intracranial extension) during index hospitalization (p < 0.05) and the presence of an infected orbital implant (p < 0.05) respectively.

CONCLUSIONS

Adult patients experience NVCOC complications more often than children. Furthermore, the nonvisual complications in children are more likely to resolve spontaneously than those in adults. The intracranial spread of infection is a significant risk factor for late complications in children. The presence of an orbital wall/floor implant is a significant risk factor for late complications in adults. There are many differences in the etiology, pathophysiology, and course of NVCOC in children and adults, so information on these two populations should be reported separately.

Orbital cellulitis with panophthalmitis and scleral necrosis - a case report

BACKGROUND

Orbital cellulitis is common in young children and is often secondary to coexisting sinus disease. Coexisting orbital cellulitis and panophthalmitis is a rare clinical event and usually occurs secondary to trauma or from an endogenous source.

CASE PRESENTATION

A febrile 2-year-old male presented with periorbital inflammation and exudative retinal detachment. Imaging showed acute sinusitis and extensive orbital cellulitis. Because of progressive scleral thinning, the patient underwent enucleation.

CONCLUSION

We present a case of concurrent orbital cellulitis, panophthalmitis, and scleral necrosis in an immunocompetent pediatric patient. Timely intervention is important to prevent life threatening complications with the rare occurrence of coexistent orbital cellulitis and panophthalmitis.

Painless Orbital Bone Infarction in a Child with Sickle Cell Anemia: A Case of Misdiagnosed Periorbital Cellulitis

BACKGROUND Sickle cell orbitopathy is a rare complication of sickle cell disease that closely mimics other conditions, such as orbital cellulitis and osteomyelitis. We report a case of painless orbital bone infarction masquerading as periorbital cellulitis in a child with sickle cell anemia. CASE REPORT A 4-year-old Saudi girl with sickle cell disease presented to our hospital with vaso-occlusive crisis characterized by bilateral lower limb pain and painless left orbital swelling. On examination, she had swelling of the left upper eyelid with redness and mild ptosis (margin reflex distance 1 was 2 mm) without proptosis. Magnetic resonance imaging with contrast showed bilateral sub-periosteal heterogeneous collections (2×0.8×2.1 cm in the superolateral wall of the left orbit and 1×0.6 cm in the inferolateral wall of the right orbit), with intermediate-to-high T1 signal intensity and high T2 signal, causing a mass effect on the adjacent superior and lateral rectus muscles. The patient was treated with systemic antibiotics and supportive treatment for vaso-occlusive crisis under the care of the pediatric team and was discharged without complications. CONCLUSIONS The diagnosis of sickle cell orbitopathy can be challenging, and an accurate diagnosis is essential to ensure appropriate management. Thus, we report the case of a 4-year-old child with painless sickle cell orbitopathy masquerading as pre-septal cellulitis.

Serologic Evaluations in the Distinction Between Sinusitis-Related Orbital Cellulitis and Periorbital Necrotizing Fasciitis

PURPOSE

While sinusitis-related orbital cellulitis (SROC) and periorbital necrotizing fasciitis (PNF) share similar clinical presentations, they are managed differently, making rapid recognition of the appropriate clinical entity critical to optimal outcomes. This study was performed to assess whether serologic testing might help clinicians to distinguish between SROC and PNF.

METHODS

A retrospective review analysis was used to compare initial complete blood counts and comprehensive metabolic panels among adult patients with SROC and PNF. Statistical evaluations were used to determine the significance of differences between the groups.

RESULTS

Thirteen patients with PNF and 14 patients with SROC were identified. The 2 groups were similar in age, gender, and likelihood of immunosuppression ( p > 0.05 for each metric). Mean leukocyte counts were 18.52 (standard deviation = 7.02) and 10.31 (standard deviation = 5.77) for PNF and SROC, respectively ( p = 0.0057). White blood cell levels were above normal limits for 12 patients with PNF (92.3%) and 7 patients with SROC (50%) ( p = 0.017). No other laboratory test was significantly different between the 2 groups.

CONCLUSIONS

While the majority of serologic testing was quite similar in patients with either SROC or PNF, leukocyte levels may represent an important clue to distinguish between the two diseases. Clinical evaluation remains the gold standard to make the proper diagnosis, but markedly elevated white blood cell counts should prompt clinicians to at least consider a diagnosis of PNF.

Transnasal endoscopic drainage of neonatal orbital abscess

Neonatal orbital complications are rare and potentially fatal, demanding prompt diagnosis and adequate treatment. A 25-day-old neonate presented with rapidly progressive orbital complications as evidenced by proptosis, chemosis, lid oedema and restricted eye movements, developing within 3 days. There was no significant medical history or risk factors for developing infection. An initial conservative approach with antimicrobial therapy failed to show any resolve. An MRI brain, orbits and paranasal sinuses demonstrated that there were features suggestive of right orbital cellulitis with possibility of abscess formation with right ethmoidal mucoinflammatory disease and mass effect on the optic nerve causing stretching and compression by the surrounding inflammation.The patient was treated successfully with transnasal endoscopic drainage and decompression. Endoscopic access was challenging owing to the restrictive anatomy. Postoperatively, the patient showed improvement, with gradual decrease in proptosis and resolve in eye movements.

Case Report: Vision Loss in a Child Caused by Streptococcus constellatus

PURPOSE

We present a rare case of Streptococcus constellatus -induced odontogenic orbital cellulitis.

METHODS

An 8-year-old boy presented to an outpatient clinic with complaints of right-sided toothache, right eye swelling, and decreased visual acuity. He was referred to a pediatric critical care department for further management. Comprehensive diagnostic assessments, such as ophthalmic examination, blood tests, computed tomography, and MRI, were performed.

RESULTS

On presentation, the best-corrected visual acuities were 20/250 and 20/20 in the right and left eyes, respectively. Examination revealed grade 2+ eyelid edema and erythema and grade 4+ chemosis and exophthalmos in the right eye. The patient displayed restricted eye movements in all directions. Blood tests revealed a total white blood cell count of 12,100 cells/μL. Axial and coronal computed tomography revealed right-sided maxillary sinus, ethmoidal sinus, and orbital abscesses. Therefore, the patient was diagnosed with septicemia, orbital cellulitis, and orbital apex syndrome in the right eye. Intravenous antibiotics were administered; paracentesis of the orbital abscess was performed under local anesthesia. However, the patient's condition worsened, resulting in a complete loss of light perception in the right eye. Accordingly, surgery was performed under general anesthesia within 24 hours of admission; the surgery involved drainage of the orbital abscess through an inferior intraorbital incision, as well as drainage of the ethmoid sinus and maxillary sinus abscesses via nasal endoscopy. A culture obtained from the orbital abscess yielded S. constellatus . The infection was managed by a combination of surgical intervention, antibiotics, steroids, and hyperbaric oxygen therapy. However, because of optic nerve injury, vision in the affected eye partially recovered to 20/200.

CONCLUSIONS

Streptococcus constellatus -induced pediatric orbital cellulitis can result in significant morbidity. The significant improvement in vision, from no light perception to 20/200, emphasizes the importance of timely diagnosis and treatment in patients who present with acute orbital cellulitis and vision loss symptoms.

Revisiting the orbital complications of acute rhinosinusitis

OBJECTIVE

The present study revisited three classification systems of orbital complications of acute rhinosinusitis (ARS) (Chandler, Mortimore & Wormald, and Velasco e Cruz & Anselmo-Lima) and observed which of them presented the best clinical applicability.

METHODS

Clinical data and CT scan findings of patients with orbital infection were retrospectively collected. To compare the three classification systems, we revised and graded all CT images accordingly, and divided the patients into four groups: Eyelid cellulitis (EC), orbital cellulitis (OC), subperiosteal abscess (SA), and orbital abscess (OA). The groups were compared regarding the presence of sinus opacification, the need for hospitalization and/or surgical treatment, and the presence of further complications/sequelae.

RESULTS

143 patients were included. The median number of sinuses involved in patients in the OC, SA, and OA groups was 2.0. ARS was rarely associated with signs of EC (present in both Chandler's and Mortimore & Wormald's classifications. The hospitalization rate was significantly lower in the EC group compared to the other three groups. Surgery was performed in all cases in the OA group, in 58.1% in the SA group, 19.4% in the OC group, and 12.5% in the EC group (p-value < 0.0001). Complications were present at higher rates in the OA group compared to the other three groups.

CONCLUSIONS

ARS was rarely associated with Eyelid Cellulitis. The stratification in the other three groups showed to be clinically relevant. Velasco e Cruz & Anselmo-Lima's classification system proved valid, simple, and effective for categorizing orbital complications of ARS.

Impact of Season on Incidence of Sinusitis-related Orbital Cellulitis

PURPOSE

To explore the impact of season on the incidence of presentation to emergency departments with sinusitis-related orbital cellulitis in the United States.

METHODS

The National Emergency Department Sample was queried to identify cases of patients with sinusitis-related orbital cellulitis. Patient's age, location, and the month of presentation were recorded. Statistical correlations were analyzed via a dedicated software package.

RESULTS

A total of 439 patients with sinusitis-related orbital cellulitis were identified. The overall incidence was higher during the winter months ( p < 0.05); while children were more likely to develop this disease during the winter ( p < 0.05), season was not statistically correlated with its incidence among adults ( p = 0.16). The incidence of orbital cellulitis was higher during the winter in the midwest and south regions of the United States ( p < 0.05 for each region), although this correlation did not apply in the northeast and west ( p = 0.60 and 0.99, respectively).

CONCLUSIONS

While sinusitis incidence increases during the winter, the relationship between season and orbital cellulitis is complex and varies by age and geographic location. These findings may help to facilitate screening protocols for this disease and to define staffing issues for emergent ophthalmic care.

Central Retinal Artery Occlusion Due to Subperiosteal Orbital Abscess Caused by Acute Sinusitis in a Child: A Case Report

Central retinal artery occlusion (CRAO) is an ophthalmic emergency and has poor visual prognosis. It is commonly found in elderly people and very rare in child. We reported an 8-year-old girl who suffered from acute sinusitis, periorbital swelling, and the visual acuity of her right eye was only light perception. She was diagnosed with CRAO, SPOA (subperiosteal orbital abscess), and acute sinusitis. Emergency treatments including surgery, antibiotics, glucocorticoids, intraocular-pressure-lowering drugs, and vasodilators were taken immediately in order to save the eyesight. The visual acuity of the right eye returned to 20/400. Conclusions: Severe intraorbital complications of acute sinusitis can lead to CRAO. Timely drainage, strong antibiotics, and glucocorticoids are the most effective methods for the treatments.

Bacterial orbital cellulitis - A review

Infections of orbit and periorbita are frequent, leading to significant morbidity. Orbital cellulitis is more common in children and young adults. At any age, infection from the neighboring ethmoid sinuses is a likely cause and is thought to result from anatomical characteristics like thin medial wall, lack of lymphatics, orbital foramina, and septic thrombophlebitis of the valveless veins between the two. Other causes are trauma, orbital foreign bodies, preexisting dental infections, dental procedures, maxillofacial surgeries, Open Reduction and Internal Fixation (ORIF), and retinal buckling procedures. The septum is a natural barrier to the passage of microorganisms. Orbital infections are caused by Gram-positive, Gram-negative organisms and anaerobes in adults and in children, usually by Staphylococcus aureus or Streptococcus species. Individuals older than 15 years of age are more likely to harbor polymicrobial infections. Signs include diffuse lid edema with or without erythema, chemosis, proptosis, and ophthalmoplegia. It is an ocular emergency requiring admission, intravenous antibiotics, and sometimes surgical intervention. Computed tomography (CT) and magnetic resonance imaging (MRI) are the main modalities to identify the extent, route of spread from adjacent structures, and poor response to intravenous antibiotics and to confirm the presence of complications. If orbital cellulitis is secondary to sinus infection, drainage of pus and establishment of ventilation to the sinus are imperative. Loss of vision can occur due to orbital abscess, cavernous sinus thrombosis, optic neuritis, central retinal artery occlusion, and exposure keratopathy, and possible systemic sequelae include meningitis, intracranial abscess, osteomyelitis, and death. The article was written by authors after a thorough literature search in the PubMed-indexed journals.

Orbital bone infarction masquerading as preseptal cellulitis in a child with sickle beta-thalassaemia

Although several ophthalmic manifestations of sickle cell disease (SCD) are common, orbital bone infarction is rare. Orbital bones have less bone marrow creating an unlikely place to develop infarction. However, having a patient with SCD presenting with periorbital swelling should warrant imaging to rule out bone infarction. We present a case of a child with sickle beta-thalassaemia who was misdiagnosed with preseptal cellulitis in the right eye. Later upon review of the subtle signs of bone infarction in imaging, she was discovered to have orbital bone infarction.

[Diagnosis and treatment of orbital complications of acute sinusitis in 51 children]

Objective:To analyze the clinical features, diagnosis and treatment of acute sinusitis related orbital cellulitis in children. Methods:The data of 51 cases with acute sinusitis comorbid with orbital cellulitis in Tianjin Children's Hospital from April 2016 to March 2021 were retrospectively analyzed. According to the extent of infection, the patients were divided into two groups:pre-septal orbital cellulitis（7 cases） and post-septal orbital cellulitis（44 cases）. The general clinical characteristics, clinical manifestations, laboratory examination and treatment were compared between the two groups. Among them, 23 cases（6 in pre-septal orbital cellulitis group and 17 in post-septal orbital cellulitis group） were cured by medicine treatment; 28 cases were cured by surgical treatment after failure of medicine treatment. Results:There was no significant difference in age, gender and medical history between the two groups. Redness, swelling, heat and pain in eyelid was the most common clinical manifestations of orbital cellulitis in children, followed by fever, headache, runny nose, eye fixation, and vision loss. WBC count and neutrophils percentage were significantly higher in post-septal orbital cellulitis group. All children were followed up for 3 months to 3 years， 1 case was lost to follow-up， 50 cases had no recurrence and recovered well. Conclusion:Orbital cellulitis is a common and rapid developing complication of sinusitis in children. Early diagnosis and effective anti-infection treatment are very important for prognosis. Orbital CT plays an important role in the determination and evaluation of this complication. When conservative treatment is ineffective, surgical drainage in time can reduce the occurrence of serious ocular sequelae.

Septic Superior Ophthalmic Vein Thrombosis in a Prothrombotic Adolescent Patient

A 14-year-old boy presented to the emergency room with 5 days of fever and periorbital edema and erythema refractory to 4 days of augmentin and clindamycin. Examination revealed normal visual acuity, mild left periorbital edema and erythema, and a (-)1 supraduction deficit, concerning for orbital cellulitis. CT imaging revealed pansinusitis, orbital cellulitis with subtle orbital fat stranding, and a dilated superior ophthalmic vein with concern for thrombosis. This was confirmed on subsequent magnetic resonance venography. He was treated with intravenous antibiotics and enoxaparin with significant improvement in 24 hours. Standard hypercoagulable workup revealed positive lupus anticoagulant and cardiolipin of unclear significance; on genetic sequencing, he was found to have a homozygous mutation of the 4G variant of plasminogen activator inhibitor-1. Plasminogen activator inhibitor-1 homozygosity is a rare predisposing hypercoagulable state. This case highlights the importance of hematologic and genetic studies in adolescent patients with superior ophthalmic vein thrombosis, particularly those with mild presentation.

[Treatment strategy of nasal orbital complications in children]

Objective:The aim of this study is to explore the treatment strategy of children's nasal orbital complications. Methods:The clinical data of 28 children with nasal orbital complications admitted to Dalian Children's Hospital from February 2018 to February 2021 were analyzed and summarized. Results:Among the 28 children, 18 were males （64.3%）, 10 females （35.7%）, 16 cases of orbital cellulitis, 10 cases of orbital subperiosteal abscess, 1 case of intraorbital abscess, and 1 case of cavernous sinus thrombophlebitis. Of the children with orbital cellulitis, 2 cases were treated with surgery, 4 cases with orbital subperiosteal abscess were treated with surgery, and the children with intraorbital abscess and cavernous sinus thrombophlebitis were treated with surgery. All the children were cured, and the clinical follow-up was more than half a year. No recurrence occurred. Conclusion:Periorbital cellulitis is the most common type of orbital complications. After conservative treatment （3-7 days）, most children can get good results. Once the visual acuity is progressively decreased, the infection becomes worse, the eyeball movement disorder and other symptoms occur at this time, surgical treatment should be actively considered, and the timing of surgery is very important for the prognosis.

Bilateral orbital cellulitis in an infant: An unusual case

Bilateral orbital cellulitis is an uncommon presentation in infants, and its association with rhinosinusitis has been scantily reported in the literature. An infant underwent bilateral uncinectomy and right ethmoidal decompression for bilateral orbital cellulitis with right ethmoidal sinusitis, after a period of non-recovery with conservative treatment. Mixed infection with Escherichia coli and methicillin-sensitive Staphylococcus aureus was observed. The right eyelid swelling began to resolve; however, the left lower eyelid showed an increase in the fluctuant swelling. Transconjunctival incision and drainage of pus was done in the left eye subsequently. The patient showed marked clinical recovery and is doing well. A multidisciplinary management approach can avert potentially life-threatening sequelae of this condition.

Silicone oil-associated orbital cellulitis with lipogranulomatous inflammation in the setting of HIV: a management challenge and clinicopathological correlation

A 58-year-old Indian man presented with pain and redness of the left eye (OS) for one day. Patient had undergone silicone oil removal in OS for emulsified oil following vitrectomy and oil tamponade six months ago when he was diagnosed with retinal detachment in both eyes due to HIV retinopathy. Retinal detachment in the right eye (OD) was inoperable and had turned prephthisical at presentation, while his vision in OS was finger counting. Intraocular pressure in OD was 8 mm Hg and unrecordably elevated in OS. Extraocular movements were limited by periorbital oedema and proptosis. Slit-lamp examination revealed corneal haze, cells 2+/flare 1+ with pseudophakia, and attached retina. Histopathology showed lipogranulomatous inflammation, hitherto unreported in association with silicone oil. The index case posed a management challenge since his only functional eye had potentially been compromised by glaucoma and orbital cellulitis with compartment syndrome, against the backdrop of an immunocompromised status.

Orbital cellulitis, sinusitis and intracranial abnormalities in two adolescents with COVID-19

We review two cases of adolescents with orbital cellulitis, sinusitis and SARS- CoV-2 infection presenting to emergency departments within a 24 hour period. SARS-CoV-2 samples obtained within 24 hours were positive, supporting prior infection despite relatively limited early symptoms of COVID-19. Unusual clinical and radiographic characteristics included hemorrhagic abscess with blood of varying age in the first, intracranial epidural abscess in the second, radiographic signal consistent with hemorrhagic or thrombotic phenomena, retro-maxillary antral fat changes, and meningeal enhancement or extension in both cases. Radiographic findings thereby mimic fungal infection, although final cultures and ancillary investigation for allergic and invasive fungal disease have remained negative. These cases highlight two unusual orbital presentations of cellulitis occurring in the context of SARS-CoV-2 co-infection.

Invasive Rhino-Orbito-Cerebral Mucormycosis in Pediatric Patient with Acute Leukemia

BACKGROUND

Invasive fungal infections are a life-threatening complication of cancer treatments, especially in hemato-oncological patients. Mucormycosis is the third leading cause of invasive fungal infections after Aspergillus and Candida infections. The first clinical symptoms are usually non-specific, which can lead to a late diagnosis and delayed therapy.

PURPOSE

The objective of this report is to summarize data in the literature about mucormycosis and to present a case report of a patient with acute lymphoblastic leukemia, who developed this infection at our center. Risk factors for the development of mucormycosis, clinical symptoms, radiology, laboratory results, and outcome were retrospectively evaluated.

CASE

We describe a 6-years-old female patient with acute lymphoblastic leukemia. During the induction phase of therapy, the patient developed febrile neutropenia and did not respond to therapy with a combination of antibiotics and supportive treatment. Pansinusitis and orbitocellulitis developed. Examination of the biological material revealed that the etiological agent was a Rhizopus sp. The patient was treated with a combination of antimycotic drugs, but the infection disseminated to the central nervous system. She underwent radical surgical resection of the affected tissue. At this time, she is still under treatment with antimycotic and oncology agents, but is in remission of the main diagnosis and in good clinical condition.

CONCLUSION

Mucormycosis is an invasive fungal infection with high morbidity and mortality. Early diagnosis and initiation of effective therapy using a combination of amphotericin B administration and surgery are necessary to obtain a favorable outcome. The authors declare they have no potential conflicts of interest concerning drugs, products, or services used in the study. The Editorial Board declares that the manuscript met the ICMJE recommendation for biomedical papers.

[Diagnosis and treatment of orbital cellulitis]

Orbital cellulitis is a rare disease usually caused by sinusitis. Generally, the prognosis of both preseptal cellulitis and orbital cellulitis is favourable. Radiological distinction should be made between an orbital abscess and subperiosteal empyema. Theoretically, empyema is more accessible to antibiotics and, as it arises in a pre-existing anatomical space, it needs less aggressive treatment than an abscess. In contrast, the wall of an abscess created by the bacteria is scarcely permeable to antibiotics. Indications for surgical drainage should be based on clinical findings and not on Chandler's classification. Loss of vision, an unresponsive pupil or a densely packed orbit are indications for immediate surgical drainage. Drainage of an orbital abscess may speed up recovery.

Periorbital cellulitis in children: Analysis of outcome of intravenous antibiotic therapy

Periorbital cellulitis is a relatively common ocular disease in the pediatric population. Early diagnosis of this disease with a prompt intervention is critical to avoid vision and life-threatening complications. In the last years, medical therapy has been expanding for the treatment of orbital cellulitis, instead of the standard surgical approach. The purpose of this study was to describe the outcome of treatment with intravenous antibiotic of periorbital cellulitis in children. A retrospective review of all children admitted with periorbital cellulitis in our hospital between January 2002 and July 2013 was conducted. Cases were divided in two subgroups, pre-septal and post-septal infection. The demographics, clinical findings, treatment and outcomes were analyzed. In total 110 children were included, 93 with pre-septal and 17 with post-septal cellulitis. The mean age was 3.5 years in children with pre-septal cellulitis and 5.5 years in those with post-septal cellulitis (p = 0.149). For both subgroups the most common predisposing factor was sinusitis. Intravenous antibiotic therapy was successful in all except one patient with an orbital abscess who required surgical intervention. In our study complete recovery was achieve in all (except for one) children with periorbital cellulitis treated with intravenous antibiotics only.

Pediatric nasal orbital cellulitis in Shenzhen (South China): Etiology, management, and outcomes

OBJECTIVES

The study aimed to investigate the clinical characteristics, diagnosis, and treatment of orbital cellulitis in children in Shenzhen, China, and to improve the experience of antibiotic therapy for the treatment of orbital cellulites.

METHODS

This retrospective study reviewed data from 20 children admitted to Shenzhen Children's Hospital between January 2009 and December 2013, with a diagnosis of nasal orbital cellulitis, severe enough to warrant hospitalization. Thirteen subjects (65%) were male and 7 (35%) were female. The median age was 3.5 years (2 months-7.2 years). The relationship between serum C-reactive protein (CRP), white blood cell count, and length of hospitalization were analyzed. The patients were categorized into 2 groups according to treatment: Those treated with a combination of cefoperazone plus sulbactam sodium vs. those treated with other antibiotic treatment regimens.

RESULTS

Levels of serum CRP (29.8 ± 22.0 mg/L) at the time of admission were positively correlated with length of hospitalization (6.3 ± 4.1 days, r = 0.46, P < 0.05). The length of time necessary for CRP levels to return to normal range after admission (3.4 ± 1.8 days) was also significantly correlated length of hospitalization ((6.3 ± 4.1)days) (r = 0.81, P < 0.01). The hospital days whose CRP can be decreased to normal within 3 days (4.3 ± 1.7 days) after antibiotic treatment were significantly shorter than the others (9.1 ± 5 days) (t = 2.61, P < 0.05). The length of hospitalization (4.3 ± 1.9 days) for patients (n = 12) receiving combined cefoperazone and sulbactam sodium antibiotic treatment was significantly shorter than the length of stay (9.3 ± 4.7 days) for those patients (n = 8) treated with other antibiotic regimens (t = 2.83, P < 0.05). Bacterial pathogens were identified in 4 patients (20%), including 3 cases of Staphylococcus aureus and 1 case of Streptococcus anginosus. Acquired methicillin-resistant Staphylococcus aureus (MRSA) were found in the three pus cultures.

CONCLUSION

Early efficient antibiotic treatment over the first three days may shorten the course of nasal orbital cellulitis and potentially prevent the formation of orbital abscesses. Clinical factors that were significantly related to patient recovery included improved clinical signs and normalization of blood CRP levels. Our results also indicate that combined cefoperazone and sulbactam sodium is effective and should be recommended for the treatment of pediatric orbital cellulitis.

Orbital Cellulitis of Odontogenic Origin

Odontogenic orbital cellulitis, although uncommon, has the potential to cause severe vision loss if unsuspected and untreated. Compared to non-odontogenic bacteriology, odontogenic orbital abscesses typically feature a heavy mixed growth with anaerobic organisms. We review the literature and discuss the case of a 26-year-old male who presented with anaerobic orbital cellulitis for treatment.

[Orbital complications of sinusitis]

Orbital complications categorised by Chandler are emergency. They need early diagnosis and agresive treatment. Stage and origin of orbital complications are identified by rhinoendoscopy, ophtalmologic examination and CT of orbite and paranasal sinuses. Periorbital cellulitis and early stage of orbital cellulitis can be treated conservatively with i. v. antibiotics. Monitoring of laboratory parameters and ophtalmologic symptoms is mandatory. Lack of improvement or worsening of symptoms within 24-48 hours and advanced stages of orbital complications are indicated for surgery. The purpose of the study is to evaluate epidemiology, clinical features and management of sinogenic orbital complications. Retrospective data of 8 patients with suspicion of orbital complication admited to hospital from 2008 to 2013 were evaluated. Patients were analyzed in terms of gender, age, CT findings, microbiology, clinical features, stage and treatment. Male and female were afected in rate 1,66:1. Most of patients were young adult in 3rd. and 4th. decade of life (62,5 %). Acute and chronic sinusitis were cause of orbital complication in the same rate. The most common origin of orbital complication was ethmoiditis (62,5 %), than maxillary (25 %) and frontal (12,5 %) sinusitis. Polysinusitis with affection of ethmoidal, maxillary and frontal sinuses (75 %) was usual CT finding. Staphylococcus epidermidis and Staphylococcus aureus were etiological agens in half of cases. Periorbital oedema (100 %), proptosis, chemosis (50 %), diplopia and glaucoma (12,5 %) were observed. Based on examinations, diagnosis of periorbital oedema/preseptal cellulitis was made in 3 (37,5 %), orbital cellulitis in 3 (37,5 %) and subperiosteal abscess in 2 cases (25 %). All patients underwent combined therapy - i. v. antibiotics and surgery within 24 hours. Eradication of disease from ostiomeatal complex (OMC), drainage of affected sinuses and drainage of subperiosteal abscess were done via fuctional endonasal endoscopic surgery (FEES). In case of superior subperiosteal abscess, combined endonasal and external approach (external orbitotomy) was needed. Combined therapy facilitated quick improvement of local and systematic symptoms. Average time of hospitalisation was 7 days. Early diagnosis and agresive combined therapy prevent loss of vision and life threatening complications.

Orbitocranial complications of acute sinusitis in children

BACKGROUND

Orbitocranial complications (OCCs) of sinusitis are uncommon but potentially life threatening. OCCs carry high morbidity, mortality, and significant long-term sequelae. Late recognition leads to even worse outcomes.

OBJECTIVE

To present four case reports showing that aggressive management of complications of sinusitis-like OCC decreases long-term sequelae and mortality in pediatric patients.

CASE REPORTS

Four pediatric patients diagnosed with OCC were treated at our institution from April 2012 to March 2013. Three were boys and one was a girl; ages ranged from 4-14 years. Magnetic resonance imaging and computed tomography were the most useful imaging modalities. All patients received broad-spectrum antibiotics. Additional interventions consisted of endoscopic sinus surgery, subdural empyema drainage, and orbital decompression.

CONCLUSION

The difficult complications of acute sinusitis in the pediatric age group should be anticipated, recognized early, and aggressively managed to prevent morbidity and a fatal outcome.

Bilateral orbital preseptal cellulitis after combined adenotonsillectomy and strabismus surgery--case report and pathogenetic hypothesis

The first case of bilateral orbital preseptal cellulitis complicating combined adenotonsillectomy and strabismus surgery is reported. The issues of antimicrobial prophylaxis are discussed. The authors speculate about the possible routes of surgical site infection. Transient bacteraemia secondary to adenotonsillectomy may be theoretically a source of distant surgical site infection to the orbit, raising the issue of distant surgical site contamination during multidisciplinary surgery. Combined adenotonsillectomy and eye surgery might benefit from prophylactic systemic antibiotic administration.

Paranasal sinus infection causing orbital subperiosteal abscess: surgical management of this devastating entity

BACKGROUND

Orbital infection is an uncommon devastating infection and is usually a complication of paranasal sinus infection. Without appropriate treatment, orbital infection may lead to serious complications, even death. Prompt treatment is mandatory to avoid visual loss or intracranial complications. The literature shows that initially, intravenous antibiotics should be administered, and after 48 h, if no improvement appears, the affected orbit and the sinuses must be surgically drained. The authors describe two cases of orbital cellulitis with a brief literature review.

CASE REPORT

The authors describe two cases of orbital abscess caused by paranasal sinus infection. In case 1, the patient presented a decreased visual acuity associated with ophthalmoplegia of the right eye. In case 2, the patient presented a decreased visual acuity. Thus, administration of intravenous antibiotic combined with surgical drainage was performed. After surgical procedure, eye movements were normalized in case 1, and in both patients, the visual acuity returned to normal parameters.

DISCUSSION

The authors recommend early surgical drainage with parenteral antibiotic administration and careful postoperative observations by monitoring the signs and symptoms of the orbital complaint.

Retrograde cavernous sinus thrombosis and orbital cellulitis secondary to meningitis in immunocompetence child

A case of cavernous sinus thrombosis is usually a complication of severe orbital cellulitis and meningitis. The authors reported a retrograde cavernous sinus thrombosis and orbital cellulitis in an immunocompetence child, due to meningitis.

Orbital cellulitis: clinical course and management challenges. the Lagos State University Teaching Hospital experience

BACKGROUND

Orbital cellulitis is a devastating acute infection of orbital soft tissues located posterior to the orbital septum. It is both vision and life-threatening. It is an ocular emergency which most often present in childhood.

OBJECTIVE

This article reviewed cases presenting during the study period with the view of examining the pattern of presentation, clinical course and management challenges.

METHODS

A retrospective study was conducted on patients presenting with orbital cellulitis between January 2008 and June 2011. Socio-demographic data, entry and discharge visual acuity, presenting complaints, predisposing factors, duration of complaints, admission period and complications were extracted from clinical records and analyzed.

RESULTS

Seventeen (17) patients presented with orbital cellulitis constituting 6.2% of ocular emergency admissions during the study period. Twelve (70.6%) were males. Thirteen (76.5%) were children. The major predisposing factors were upper respiratory tract infections, and facial and globe injuries in five (22.7%) cases respectively. Only five (29.4%), presented within three days of disease onset. Average duration of admission was 10.6 days. Complications during the course of disease were category 4 and 5 blindness in five (23.5%), orbital abscess four (23.5%), cavernous sinus thrombosis two (11.8%), contralateral preseptal cellulitis two (11.8%) and exposure keratopathy in one (5.9%).

CONCLUSION

Orbital cellulitis has remained a disease with high ocular morbidity. The major management challenges were poor financial status of patients precluding necessary diagnostic laboratory and imaging studies. Early recognition, diagnosis and treatment are crucial to the preservation of vision and reduced occurrence of complications. The importance of record keeping is also highlighted.

A multi-centre case series investigating the aetiology of hypertrophic pachymeningitis with orbital inflammation

INTRODUCTION

To describe our attempt in establishing a definitive diagnosis in patients with hypertrophic pachymeningitis in combination with orbital inflammatory disease and report on the outcome.

MATERIALS AND METHODS

This was a retrospective case series of all patients presenting with hypertrophic pachymeningitis in association with orbital inflammation in 4 centres. Ophthalmic and neurological examination data, laboratory data, histology data, treatment plans and clinical outcome data were recorded. Patients underwent orbital/brain computed tomography and magnetic resonance imaging.

RESULTS

Six patients were identified; the median age was 46.5 years. Headache was the commonest presenting symptom, followed by diplopia and reduced visual acuity. Three patients underwent orbital biopsy, 1 patient underwent dura mater biopsy, 1 patient underwent both and 1 patient underwent nasal biopsy. Four patients were diagnosed with Wegener granulomatosis and 2 patients with tuberculosis. Corticosteroid therapy was initiated in 4 patients, with steroid-sparing drugs added later. Two patients received anti-tuberculosis treatment and 1 patient was commenced on pulsed cyclophosphamide. On follow-up, 1 patient required an exenteration for a painful blind eye and 1 patient's visual acuity remained at no perception to light. One patient had complete resolution of symptoms on treatment, 1 patient had persistent reduced visual acuity and 1 patient was lost to follow-up.

CONCLUSION

We postulate that the combination of orbital inflammation and pachymeningitis is strongly suggestive of Wegener granulomatosis, although it may take a number of years to confirm. Tuberculosis should also be considered.

Rhinocerebral mucormycosis: an update

BACKGROUND AND OBJECTIVES

Mucormycoses are a group of invasive infections caused by filamentous fungi of the Mucoraceae family, with the rhinocerebral form of the disease being the most common in large case series. In the present paper we review the characteristics of the rhinocerebral form of the disease.

EVIDENCE AND INFORMATION SOURCES

The present review is based on the analysis of the current literature on rhinocerebral mucormycosis.

STATE OF THE ART

Rhinocerebral mucormycosis is associated with immunocompromised patient state, haemochromatosis, desferrioxamine therapy and prolonged corticosteroid therapy. Uncontrolled diabetes and increased serum iron are regarded as the two leading predisposing factors for the development of the disease. Currently, treatment for the disease is based on three main principles; rapid reversal of underlying predisposing factors, antifungal therapy with amphotericin B and timely surgical intervention.

PERSPECTIVES

Antifungal drugs of the azole group and new iron chelating agents--deferasirox, deferiprone--have been supported as alternative options to amphotericin B or as salvage therapy.

CONCLUSIONS

Rhinocerebral mucormycosis requires a high level of awareness if early diagnosis and treatment is to be achieved. Large scale evaluation of arising treatment options is a mandatory course of action in the future research of the disease.

Acute dacryocystitis causing orbital cellulitis and abscess

PURPOSE

Acute dacryocystitis commonly presents as preseptal cellulitis as lacrimal sac lies anterior to the orbital septum and hence infection localizes in the preseptal space. The purpose of this study is to describe presentation and management of cases of acute dacryocystitis presenting as orbital cellilitis and abscess secondary to acute dacryocystitis.

METHOD

This retrospective, non-comparative, interventional case series included 6 patients presenting with orbital cellulitis and abscess secondary to acute dacryocystitis. All patients underwent drainage of abscess under general anesthesia. External dcaryocystorhinostomy was advised as the definitive treatment for all pateints.

RESULT

Abscess was localized in the extraconal space in 4 patients and in the intraconal space in 2 patients. Patients with intraconal abscess had visual loss on presentation while vision could be preserved in patients with abscess in extraconal space. Both patients with intraconal abscess had history of acute dacryocystitis.

CONCLUSION

Acute dacryocystitis is an ophthalmic emergency that can cause orbital cellulitis with abscess formation, and even vision loss, if left untreated.

[Inflammatory diseases of the orbit]

Inflammatory conditions belong to the most important diseases of the orbit. Children and adolescents are mostly affected and the most common cause is secondary pathogen invasion from acute sinusitis. However in adults most cases involve idiopathic orbital inflammation, previously termed pseudotumor orbitae. Clinical presentation may include painful exophthalmus, skin redness and warming, chemosis and disturbed eye motility. The challenge for imaging investigations, mainly a combination of CT scanning and MRI, is to distinguish inflammatory from malignant conditions, to define the extent of lesions and to document possible complications, such as cavernous sinus thrombosis, meningoencephalitis or cerebral abscesses. Serious potential consequences of orbital infections, including loss of vision or death, are still a risk factor and must be averted by avoidance of delays in diagnosis and appropriate clinical management.
