OBJECTIVE: To explore the clinical characteristics, diagnosis, and treatment methods of one patient with idiopathic multicentric Castleman disease (iMCD), in order to strengthen the understanding of this rare disease. METHODS: The clinical manifestations, diagnosis and treatment process, and prognosis of one patient with iMCD admitted to our hospital were retrospectively analyzed. RESULTS: The patient was a 45-year-old female with swollen bilateral orbit, edema of lower limbs, multiple serosal cavity effusion, thrombocytopenia, renal insufficiency, and multiple lymph node enlargement. Lymph node biopsy suggested mixed type of Castleman disease. Combined with pathology, imaging and laboratory examination, the patient was finally diagnosed with mixed type of iMCD. After six cycles of R-COP regimen chemotherapy, the patient achieved complete remission. CONCLUSIONS Castleman disease with renal and orbit involvement is rare in clinic and easy to be misdiagnosed. It should be distinguished from lymphoma. The patient has been treated with R-COP regimen, and obtained good short-term efficacy.

PURPOSE: To report a case of immunoglobulin G4 (IgG4)-related ophthalmic disease associated with adult xanthogranulomatous disease. CASE SUMMARY: A 38-year-old male with a history of cholecystectomy visited our clinic for bilateral periorbital swelling. Histopathology of the orbital biopsy showed diffuse infiltration of foamy histiocytes with Touton giant cells and lymphoid follicles, with a diagnosis of adult-onset xanthogranuloma. After excisional biopsy, he was treated with azathioprine and prednisolone. Four years after treatment, he again visited the clinic due to bilateral, yellowish eyelid masses. Serological examinations were all nonspecific findings, except for elevation of IgG and IgG4 levels. Magnetic resonance imaging showed bilateral symmetric soft tissue enlargement with slightly heterogeneous T1/T2 isosignal intensity, with contrast enhancement at the superolateral aspect of extraconal spaces. Excisional biopsy and blepharoplasty were performed. Immunohistochemical sections showed that the IgG4+/IgG plasma cell ratio was 10–20% and the IgG4 plasma cell count was 22/high power field (HPF). His past sections of 2013 from the pathology department were again stained and showed that the IgG4+/IgG plasma cell ratio was 40–50% and the IgG4 plasma cell count was 59/HPF. Thus, he was definitely diagnosed with IgG4-related ophthalmic disease. CONCLUSIONS: If there is recurrent eyelid swelling, IgG4-related ophthalmic disease should be considered as a differential diagnosis. And the patient with adult xanthogranulomatous disease can be diagnosed with IgG4-related ophthalmic disease.

OBJECTIVE: Choroidal metastases (CMs) are the most common intraocular tumor. Management is mainly radiation therapy with goals of pain control and visual improvement. However, many radiation-related complications are reported. Since gamma knife radiosurgery (GKS) for CM was first reported in 1995, few cases have been reported. We report 7 cases of CMs treated with GKS.METHODS: From April 2011 to November 2014, 7 patients with CM underwent GKS. Their median age at treatment was 64 years (range, 51–71 years). Four males and three females were treated. Lung cancer was the most common primary pathology, followed by renal cell carcinoma and stomach cancer. Four patients had multiple cerebral lesions and were treated simultaneously for choroidal lesions. The median marginal dose of 20 Gy (range, 15–25 Gy) was administered at the 50% isodose line.RESULTS: Median follow-up period after GKS was 8 months (range, 2–38.3 months). Four patients expired due to underlying malignancy progression. Except for two patients who were not followed with magnetic resonance image after GKS, all patients showed size reduction in the treated lesions, but a new choroidal lesion appeared in one patient and one recurred. Six of seven patients reported subjectively improved visual symptoms. Visual acuity improved in 2 patients, and 2 were stable upon objective examination. One patient showed no improvement in visual acuity, but ocular pain was relieved; another patient showed improved vision and tumor remission, but visual deterioration recurred.CONCLUSION: GKS was shown to be safe and effective and should be considered for CM treatment.

To investigate the behavioral and biomolecular similarity between neuralgia and depression, a trigeminal neuralgia (TN) mouse model was established by constriction of the infraorbital nerve (CION) to mimic clinical trigeminal neuropathic pain. A mouse learned helplessness (LH) model was developed to investigate inescapable foot-shock-induced psychiatric disorders like depression in humans. Mass spectrometry was used to assess changes in the biomolecules and signaling pathways in the hippocampus from TN or LH mice. TN mice developed not only significant mechanical allodynia but also depressive-like behaviors (mainly behavioral despair) at 2 weeks after CION, similar to LH mice. MS analysis demonstrated common and distinctive protein changes in the hippocampus between groups. Many protein function families (such as cell-to-cell signaling and interaction, and cell assembly and organization,) and signaling pathways (e.g., the Huntington's disease pathway) were involved in chronic neuralgia and depression. Together, these results demonstrated that the LH and TN models both develop depressive-like behaviors, and revealed the involvement of many psychiatric disorder-related biomolecules/pathways in the pathogenesis of TN and LH.

Rhabdomyosarcoma is a kind of skeletal muscle ifferentiation tendency of primitive mesenchymal malignant tumor. It is common in pediatric malignant pleomorphic rhabdomyosarcoma, and its prognosis is poor. It is easy to relapse, and its predilection sites in head and face were around the eyes, the external auditory meatus, nasal cavity and paranasal sinuses. We should take comprehensive treatment including surgical operation, radiotherapy and chemotherapy drug combination for embryonal rhabdomyosarcoma.

OBJECTIVE: Knowledge of cranial suture morphology is crucial in emergency medicine, forensic medicine, and maxillofacial reconstructive surgery. This study assessed the visibility of sutures of the orbit and periorbital region on multidetector computed tomography. MATERIALS AND METHODS: Multidetector computed tomography scans of 200 patients (127 males, 73 females; mean age 51.3 years; range, 6-92 years) were evaluated retrospectively. The slice thicknesses varied from 0.5 to 1 mm, and the tube current from 25 to 370 mAs, depending on the CT indication. The visibility of sutures was estimated according to a 4-point scale from "not visible" to "well visible". The chi-squared test was used to test the association of the visibility of sutures with the slice thickness, tube current, and age of patients. Statistical significance was assumed at p < 0.05. RESULTS: Overall, best visibility was found for the sutura frontozygomatica (98%), sutura frontonasalis (88.5%), and sutura sphenozygomatica (71.5%), followed by the sutura zygomaticomaxillaris (65.8%), sutura temporozygomatica (41.8%), sutura frontomaxillaris (44.5%), and sutura sphenofrontalis (31%). Poor visibility was found for the sutura frontolacrimalis (16.8%) and sutura frontoethmoidalis (1.3%). The sutura ethmoidomaxillaris, sutura lacrimomaxillaris, and sutura ethmoidolacrimalis were not visible. CONCLUSION: Although the sutures of the superior, lateral, and inferior orbit are well visible, those of the medial orbit are poorly visible on CT scans.

OBJECTIVE: To review the clinical manifestations and management of nasal sinus mucoceles invaded the skull base and orbit. METHOD: Medical records for 30 patients of paranasal sinus mucoceles invaded the skull base and orbit were reviewed retrospectively. CT and MRI were important tools for diagnosing nasal sinus mucocele. The patients received endoscopic surgery to remove mucocele, some of them were operated auxiliary incision. Steroid therapies were given after the operations and routine examination with endoscopy were carried out during follow-up. RESULT: All cases were successfully performed surgery without complications after the surgeries, or the majority of symptoms. However, vision recovery was observed only in some patients. Recovery of vision depended on the timing of surgery and severity of initial visual loss. Delay treatment can seriously compromise the recovery of vision impairment. Moreover, the patients without light perception before surgery had poor visual recovery even when optic nerve decompressions were performed. CONCLUSION Endoscopic surgery has effect on nasal sinus mucocele with visual loss. Because visual recovery depends on prompt diagnosis and surgical intervention,a good understanding of the disease and prompt imaging studies are important.

OBJECTIVE: To analyze the features of orbital fracture and to discuss its forensic expertise points. METHODS: One hundred and thirty cases of simple orbital fracture from 2010 to 2012 collected from one public security bureau were retrospectively analyzed such as age, gender, tools, position and morphology of the fracture, periorbital and orbital compound injury and the follow-up results after 6 months. RESULTS: In the 130 cases, the wounded were mainly young men and hit by fist. The fracture of simple medial orbital wall accounted for up to 81.5% in all cases. In the periorbital and orbital compound injury, laceration and contusion of eyelid and ethmoidal cellules and maxillary sinus always occurred. After 6 months follow-up, there were 30 cases of comminuted fracture remained enophthalmos compared with the uninjured side. CONCLUSION It is inappropriate to judge the fracture of simple medial orbital wall as minor injury. We should judge the degree of simple orbital fracture after the injury is stable. Detailed ophthalmology inspection is necessary for forensic expertise of simple orbital fracture.
