The most frequently reported adverse reaction to zoledronic acid is an acute phase reaction resembling influenza. While rarer adverse events such as osteonecrosis of the jaw and atypical femoral fractures have gained significant recognition, the ocular adverse effects, particularly scleritis, are not yet fully comprehended. Here, we present the case of a 75-year-old female patient with osteoporosis who developed bilateral redness and intense eye pain 48 h after receiving a 5 mg intravenous dose of zoledronic acid. Clinical presentation suggested bilateral conjunctivitis, but treatment with levofloxacin eye drops and acyclovir ophthalmic gel exacerbated the symptoms over 2 days, predominantly affecting the left eye. Ocular ultrasonography revealed thickening of the left eyeball wall with a "T" sign, while an orbital CT scan showed increased thickness of the left sclera. Treatment with methylprednisolone 80 mg intravenous infusion twice daily led to gradual symptom improvement and eventual resolution of inflammation. This report, based on a review of relevant literature, investigates the treatment and outcomes of zoledronic acid-induced scleritis, emphasizing the importance for clinicians to promptly identify and manage this rare and serious ocular adverse reaction.

BACKGROUND
PD-1 inhibitors exhibit efficacy in managing unresectable/metastatic driver gene-negative NSCLC, albeit with potential immune-related adverse events (irAEs). Among these, immune checkpoint inhibitor-associated myocarditis (ICI-M) is rare yet lethal. This study presents the initial successful instance of ICI-M in a lung cancer patient, rescued by low-dose glucocorticoids post-deterioration during treatment.
CASE SUMMARY
A 78-year-old male with a medical history of stage IV pT3N2M1 NSCLC underwent four cycles of palliative chemotherapy, resulting in stable disease (SD). Subsequent to declining further chemotherapy, the patient was transitioned to a targeted therapy regimen comprising Anlotinib in conjunction with PD-1 inhibitor immunotherapy. On the 26th day post-administration of the PD-1 inhibitor, the patient manifested Grade 2 immune-mediated myocarditis. Treatment encompassing 1mg/kg methylprednisolone combined with immunoglobulin shock therapy was initiated for 3 days, achieving symptomatic control. Nonetheless, upon tapering methylprednisolone dosage to 4-8mg/3-4d, the condition deteriorated, necessitating transfer to the intensive care unit. Methylprednisolone dosage was escalated to 80mg/day for 3 days, followed by gradual reduction by one-third to two-thirds weekly, culminating in the patient's safe discharge from the hospital.
CONCLUSION
Immune-related myocarditis linked to checkpoint inhibitors is often managed effectively with high-dose glucocorticoid therapy. However, in Asian populations, low-dose glucocorticoids are increasingly utilized for salvage therapy, yielding favorable outcomes and improving prognosis compared to European populations.

Multifaceted Cerebral Venous Thrombosis With Extensive Intra-cerebral Hemorrhage in a Young Man With Mitral Valve Replacement Due to Thrombosis and IgA Nephropathy: A Challenging Case Report From Saudi Arabia.
Cerebral venous thrombosis (CVT) is a cerebrovascular condition characterized by cerebral venous sinus thrombosis, resulting in venous infarction. The condition can manifest through a range of signs and symptoms such as headaches, benign intracranial hypertension, subarachnoid hemorrhage, localized neurological deficits, seizures, unexplained changes in consciousness, and meningoencephalitis. Its causes are linked to numerous different conditions and factors. We report a complicated case and course of antiphospholipid antibody syndrome in a young patient. The case began two years prior, involving a 33-year-old man who had chronic kidney disease due to IgA nephropathy, pneumonia, and a large mass on his native mitral valve. He developed deep vein thrombosis (DVT) in his upper limb, for which he was prescribed warfarin. He was transferred to our hospital with a five-day history of severe headaches followed by a decrease in consciousness and seizures requiring intubation. He was found to have a subdural hematoma with a high international normalized ratio (INR). He underwent hematoma evacuation and a right decompressive craniotomy. CT of the brain via CT venography revealed intracerebral haemorrhage along with ischemic infarction in the right frontal-parietal and temporal lobes and cerebral venous thrombosis. He was treated with heparin infusion but later developed heparin-induced thrombocytopenia (HIT) and was switched to fondaparinux. Plasma exchange and intravenous methylprednisolone were given. His hospital course was complicated by recurrent infections, a new left intraparenchymal hemorrhage with intraventricular extension, and the need for extra ventricular drainage (EVD). The diagnosis of antiphospholipid antibody syndrome was confirmed. This case report provides invaluable insights into managing a complex scenario that requires balanced decisions between anticoagulation in the context of severe ICH and the necessity of immunosuppressive therapy. The emphasis is on the significance of using a personalized and multidisciplinary strategy to address CVT situations and their issues.

Longitudinally extensive myelitis with 15 or more vertebrae in length is extremely rare, with limited evidence regarding clinical features and therapeutic response. We report a case of a 29-year-old male patient with extremely longitudinally extensive myelitis ultimately diagnosed as myelin oligodendrocyte glycoprotein-associated disease (MOGAD). The patient presented with an acute onset of meningismus, limb weakness, sensory disturbance below the C5 level, ataxia, and urinary retention. T2-weighted imaging on MRI showed an extremely longitudinally extensive spinal cord lesion ranging from C2 to the medullary conus, together with a left pontine lesion. Positive anti-myelin oligodendrocyte glycoprotein antibodies were serologically detected, which led to the diagnosis of MOGAD. Intravenous methylprednisolone followed by 1 mg/kg oral prednisolone with taper resulted in complete symptomatic and radiological resolution. The striking complete resolution despite the symptomatic and radiological severity observed in this case has been described in a few previously reported MOGAD cases. Extremely longitudinally extensive myelitis with excellent therapeutic response may be a characteristic presentation of MOGAD.

Neuromyelitis optica spectrum disorder (NMOSD) is a rare central nervous system disease presenting as optic neuritis, myelitis, and brainstem syndromes. It may be aquaporin-4 seropositive, anti-myelin oligodendrocyte glycoprotein (MOG) antibody seropositive, or double seronegative. Double-seronegative NMOSD can pose a diagnostic and therapeutic challenge. Treatment typically aims to decrease the incidence of relapse, for which high-dose intravenous methylprednisolone is the first-line agent. Non-steroid treatments include azathioprine, mycophenolate mofetil, and rituximab. This case describes a 45-year-old female presenting with left arm numbness and weakness for three months. She had been previously diagnosed with optic neuritis in 2013 but was lost to follow-up. Progression of weakness warranted admission to the neurology department. Diagnostic work and imaging were suggestive of neuromyelitis optica. Tests for aquaporin-4, anti-MOG, immunoglobulin G, and immunoglobulin M in the cerebrospinal fluid were all negative. Initial treatment comprised methylprednisolone; however, due to the progression of symptoms, she was given two cycles of rituximab. Rituximab targets the CD20 antigen in B cells and is thought to reduce the risk of relapse and the severity of NMOSD. The patient's Barthel index score, expanded disability status scale score, and motor examination improved after two cycles of rituximab.

PURPOSE
This study aims to report correlations between thyroid-stimulating immunoglobulin(TSI) and both clinical and radiological parameters in recent-onset symptomatic thyroid eye disease(TED) patients.
METHODS
A prospective cohort study of TED patients managed at the Chinese University of Hong Kong from January 2014 to May 2022. Serum TSI levels were determined with the functional assay. Outcomes included the clinical activity score(CAS), marginal reflex distance1(MRD1), extraocular muscle motility restriction(EOMy), exophthalmos, and diplopia. The radiological assessment included cross-sectional areas and signal of extraocular muscles on STIR-sequence MRI.
RESULTS
A total of 255(197female) treatment-naïve patients, with an average onset age of 50±14 years, were included. Elevated pre-treatment TSI level was observed in 223(88%) patients. There was a weak positive correlation between TSI and CAS(r=0.28, P=0.000031), MRD1(r=0.17, P=0.0080), and the size of the levator palpebrae superioris/superior rectus complex(r=0.25, P=0.018). No significant correlation existed between TSI and STIR signals. The AUC and optimal cut-off value for clinical active TED were 0.67(95% confidence interval:0.60-0.75) and 284%(Specificity:50%, sensitivity:85%). 64 patients received intravenous methylprednisolone (IVMP) during the study interval, and they had a higher baseline TSI level than those who did not have IVMP(P=0.000044). Serial post-IVMP TSI among the 62 patients showed a significant reduction compared to the baseline level(P<0.001). Both the baseline and post-IVMP TSI levels, and percentages of TSI changes were comparable between patients who responded and non-responded to the first course of IVMP.
CONCLUSION
TSI can be a serum biomarker for the diagnosis, prognosis, and treatment response of TED. Further validation should be further warranted.

The anti-CASPR2 antibody-associated syndrome is a rare immune-mediated disorder. Most case reports describe neurologic symptoms that include encephalic signs, peripheral nerve hyperexcitability, dysautonomia, or neuropathic pain. We report the case of a 70-year-old man, admitted to the emergency department with complaints of slurred speech and imbalance. Neurological examination was relevant for dysarthria, hyperreflexia, and pancerebellar syndrome. Cranial CT and basic laboratory tests were normal and he spontaneously recovered after 14 hours. Over the next four months, the patient experienced three similar episodes in relation to stressful events (emotional and organic disturbances like prolonged fasting and vaccination). A contrast-enhanced MRI was performed, along with extensive laboratory testing, analysis of cerebrospinal fluid (CSF), paraneoplastic investigation, and next-generation sequencing panel for episodic ataxias. The results revealed oligoclonal bands in the CSF and positive anti-CASPR2 antibodies both in serum and CSF. Three-day-IV- methylprednisolone pulse followed by plasmapheresis and monthly intravenous immunoglobulins was performed with good response. In conclusion, the neurological manifestations that led to the diagnosis of anti-CASPR2 antibody-associated syndrome were intermittent self-limiting episodes of ataxia, often triggered by concurrent stress-inducing factors. This case supports the aim of other authors to add paroxysmal cerebellar ataxia to the spectrum of the anti-CASPR2 antibody syndrome.

Phantom limb pain (PLP) is difficult to control, and patients frequently exhibit inadequate relief from medications or encounter unbearable side effects. We present here a novel application of erector spinae plane (ESP) block to manage PLP. Our patient is a 23-year-old, college student, diagnosed with high-grade osteosarcoma of the right humerus who underwent a right shoulder disarticulation. He reported PLP despite multimodal analgesia postoperatively. An ESP block using a high-frequency linear probe ultrasound was performed. A G23 spinal needle was advanced in-plane toward the right T3 transverse process. After negative aspiration, 20 mL of therapeutic solution containing bupivacaine 0.25%, lidocaine 1%, epinephrine 5 mcg/ml, and 40 mg methylprednisolone was injected. After the procedure, the patient reported that his PLP went down to NRS 1/10. He consistently reported to have an NRS score of 0-1/10 on succeeding consultations despite discontinuation of opioid and pregabalin. In literature, ESP block has been used as a regional technique for shoulder disarticulation surgery and other neuropathic pain conditions, but no account has shown its use for PLP treatment. The procedure was successfully done to alleviate the upper extremity phantom limb pain, significantly reduce analgesic requirements, and improve tolerance of physical therapy and overall quality of life.

This case report describes a complicated case of giant cell arteritis (GCA) with tongue necrosis and bilateral central retinal artery occlusion (CRAO). An 81-year-old male patient with a history of recent retinal artery occlusion, ischemic stroke, and hypertensive emergency was evaluated. Clinical examination, including a visual acuity assessment, fundus evaluation, and oral examination, was performed. Laboratory investigations, such as erythrocyte sedimentation rate (ESR), were conducted. A temporal artery biopsy was performed to confirm the diagnosis of GCA. The patient presented with sudden vision loss in the left eye following a prior episode of retinal artery occlusion in the right eye. Ophthalmoscopic examination revealed CRAO in the left eye. Additionally, tongue necrosis, a rare manifestation of GCA, was observed. The ESR was significantly elevated. A temporal artery biopsy supported the diagnosis of GCA. The patient was promptly referred for immunologist consultation and initiated on intravenous methylprednisolone therapy. This case highlights the diverse and potentially devastating nature of GCA, involving ocular and systemic manifestations. Bilateral CRAO and tongue necrosis are rare but significant complications of GCA. Prompt diagnosis and early initiation of corticosteroid therapy are crucial to prevent irreversible visual loss and further complications. A multidisciplinary approach involving ophthalmologists and other specialists is essential for the comprehensive management of GCA.
