ABSTRACT
Background: Melioidosis is uncommon but endemic in Southeast Asia and parts of Northern Australia. Cerebral melioidosis is rare but can be spread through several routes, such as hematogenous spreading or the direct inoculation of organisms from wound contamination with soil. It can cause devastating sequelae if the treatment is delayed. However, with early and adequate treatment, patients can recover and have a good quality of life. Case Description: A 62-year-old diabetic male presented with epilepsy 2 months after a head injury. A computed tomography scan revealed an abscess extending from the subgaleal layer to the subdural with osteomyelitis. A craniotomy was performed to remove the abscess. Melioidosis was identified from pus culture. Intravenous meropenem with Bactrim was started, followed by oral doxycycline and bactrim. The patient recovered with no seizure episodes. This patient showed a rare but straightforward infection from direct inoculation in a wound contaminated with soil. Incubation time could be up to 2 months. The infection originates from previously lacerated scalp tissue and invades the skull, causing osteomyelitis and epidural abscess. Prompt treatment brings a good outcome. In patients with risk factors and a suspicious history, broad-spectrum antibiotics should be initiated after removal of the abscess. Conclusion: Melioidosis is still endemic in Thailand. Doctors should be aware of this organism in patients with high-risk factors or travelers who have just returned from an endemic area. Patients should be treated early with an adequate dose and duration of anti-melioidosis.
ABSTRACT
Background: Resection of bilateral parasagittal meningiomas of the dominant cortex is challenging. Some postoperative consequences are difficult to predict due to their low incidence. However, it is essential to recognize reversible symptoms. Akinetic mutism is a devastating but reversible symptom that occurs after supplementary motor area (SMA) injury. This report aims to provide more information to support the clinical progression of this syndrome. Case Description: A 47-year-old woman presented with psychomotor retardation and subtle weakness, particularly on the left side. A palpable mass was identified at the head vertex. Magnetic resonance imaging revealed bilateral parasagittal meningiomas with bone and sinus invasion of the SMA. A craniotomy was performed to remove the intracapsular tumor. Two days after the operation, the patient developed gradual deterioration in her motor function until it became a lock-in-like syndrome. Then, 1.5 months after treatment in the hospital and rehabilitation unit, she gradually improved her motor, cognitive, and psychomotor skills. Total recovery was achieved after 1 year. Conclusion: Surgery for lesions involving bilateral SMA can cause akinetic mutism. The typical manifestation of this syndrome may be devastating. However, it is reversible, and patients can regain full motor and cognitive functions over time without specific treatments. It is crucial to persevere and continue to provide the best care to the patient until recovery.
ABSTRACT
Objective Meningiomas are the most common extra-axial tumors of the central nervous system. Meningiomas are particularly problematic when they invade deep or vital structures, causing the tumors to be inoperable. Nonsurgical adjunctive or salvage treatments to shrink a meningioma with multiple recurrences, located in deep-seated area or surgically unfit area, remain underexplored. The authors report a rare case of a spontaneously necrotic meningioma (World Health Organization [WHO] grade I) in a patient with systemic lupus erythematosus on chronic methotrexate and hydroxychloroquine. Case Study A 29-year-old female with systemic lupus erythematosus had been treated with methotrexate and hydroxychloroquine for 7 years. She presented with episodes of seizures and hemiparesis. Neuroimaging revealed a possible necrotic meningioma in the left parietal parasagittal area. Subsequent intraoperative findings showed lytic tissue of the tumor, and by histopathology results the tumor was classified as WHO grade I with massive necrosis. After craniotomy with tumor removal, the patient's motor function fully recovered without recurrent seizures. Discussions Necrotizing of small and benign meningioma is rarely found but otherwise interesting. The cause of this phenomenon is not yet understood thoroughly. In this case, we suspected various possible causes such as vasculitis interrupting blood supply, use of immunosuppressive drugs such as hydroxychloroquine or methotrexate, or, less likely, latent infections in the immunocompromised patient. Despite the lack of more evidence supports, this finding encourages further study of nonsurgical or salvage treatment of inoperable meningioma, so sequalae after refractory recurrences of meningioma can be prevented, and patient treatment outcomes can be improved.
ABSTRACT
BACKGROUND: Treatments for lumbar discectomy have developed over time. Recently, endoscopy has played an important role. However, a major obstacle to endoscopy in rural areas is the cost of surgery, particularly for endoscopes and disposable equipment. We assessed the cost effectiveness of endoscopic lumbar discectomy compared to the traditional open microdiscectomy technique in a government hospital in a developing country. METHODS: This study focused on 50 patients who underwent endoscopic lumbar discectomy between April 2019 and March 2020 at Yala Regional Hospital and were reviewed by our team. The duration of hospital stays, operative time, follow-up, and clinical outcomes at one, three, and six months postoperatively were observed and compared with 30 patients who underwent microscopic lumbar discectomy. Hospital expenses were calculated and compared using t-tests. RESULTS: Endoscopic discectomy was 4.00 days length of stay while microscopic discectomy has 9.77 days in averages. The pain score was 8.82 for endoscopic surgery and 9.1 for microscopic surgery. The operative price for the endoscopic discectomy was 144.69 USD higher than that for the open lumbar discectomy because of the disposable equipment. However, each patient in the microdiscectomy group had a longer hospital stay and required more perioperative care, which decreased the difference of the total hospital expenses (1,420.612 vs 1,399.16 USD). CONCLUSION: Full endoscopic lumbar discectomy is an effective procedure that is beneficial for patients. The total hospital costs are not significantly different between the two procedures. To ensure that more patients receive this benefit and to develop surgical competency in government hospitals, the surgical reimbursement fee for endoscopic discectomy should be more affordable than that for conventional discectomy.
