Brain paracoccidioidomycosis (PCM) or neuroparacoccidioidomycosis (NPCM) is a fungal infection of the central nervous system (CNS) caused by
, a dimorphic fungus. The CNS involvement is through bloodstream dissemination. The association between NPCM and systemic lupus erythematous (SLE) is rare. However, SLE patients are under risk of opportunistic infections given their immunosuppression status.
The aim of this case report is to present a 37-year-old female with diagnosis of SLE who presented with progressive and persistent headache in the past 4 months accompanied by the right arm weakness with general and neurologic examination unremarkable. The computerized tomography of the head showed left extra-axial parietooccipital focal hypoattenuation with adjacent bone erosion. The brain magnetic resonance imaging reported left parietooccipital subdural collection associated with focal leptomeningeal thickening with restriction to diffusion and peripheral contrast enhancement. selleck chemicals llc The patient underwent a left craniotomy and dura mater biopsy showed noncaseous granulomatosis with multinucleated giant cells with rounded birefringent structures positive for silver stain, consistent with PCM. Management with itraconazole 200 mg daily was started with a total of 12 months of treatment, with patient presenting resolution of headache and right arm weakness.
The diagnosis of NPCM is challenging and a high degree of suspicious should be considered in patients with persistent headache and immunosuppression.

Aneurysmal bone cysts (ABC) are benign osteolytic lesions of the metaphyseal regions of long bones that typically contribute to rapid bony expansion. Here, we present an ABC involving the spinopelvic region in a 15-year-old male that required embolization, surgical excision, and fusion.
A 15-year-old male, presented with gradually progressive painful lower back swelling of 4 months' duration. Once the diagnosis of an ABC was established based on a combination of X-ray, MR, and CT studies, he underwent selective arterial embolization, extended surgical excision (i.e. curettage), with a posterior fusion. Two years postoperatively, the patient remained neurologically intact without radiographic evidence of lesion recurrence.
Large expansile ABC involving the vertebral bodies should be managed with preoperative selective arterial embolization, surgical decompression/curettage, and spinopelvic fixation.

There is lack of consensus regarding best operative fixation strategy for periprosthetic femoral fractures (PFFs) around a stable stem. Evidence exists that some patterns of fracture around a stable stem are better treated with revision surgery than with standard fixation. Anyway, a more aggressive surgical procedure together with medical treatment could allow for stem retention, and reduced risk of nonunion/hardware failure, even in these cases.
This paper is placed in a broader context of lack of studies on the matter, and its aim is to shed some light on the management of PFFs around a stable stem, when peculiar mechanical and biological aspects are present.
Based on our casuistry in the treatment of nonunions after PFF successfully treated with original stem retention, and on review of Literature about risk factors for fixation failure, an algorithm is proposed that can guide in choosing the ideal surgical technique even for first-time PFFs with a stable stem, without resorting to revision. MechanicSystemic and local biological conditions should be taken into account, as well. A therapeutic algorithm is proposed, given the prosthetic stem to be stable, considering mechanical and biological criteria.
Lumbar discectomy is a common and effective treatment for symptomatic disk herniation. It has been suggested that lumbar discectomy in older patients may result in poorer clinical outcomes and lesser satisfaction. The purpose of this study was to assess age-related difference in patient reported outcomes of patients undergoing lumbar discectomy for chronic low back and radicular pain.
Patients with chronic lumbar radiculopathy without neurological deficit underwent non-urgent single level lumbar discectomy in our institution between 2014 and 2017. Pain level (using VAS score), Oswestry Disability Index, and SF-12 scores were retrospectively reviewed and compared between younger patients (<60years, group 1) and older patients (>60years, group 2).
Seventy-three patients, aged between 34-76years participated in this study. VAS, ODI, and SF-12 scores improved significantly after the surgery for each group (
< .01). When comparing between the groups, no significant differences in the outcomes measured were found after the surgery in both early post-operative follow-up and late post-operative follow-up (
> .05).
Elderly patients undergoing lumbar discectomy report a significant reduction in VAS, ODI, and SF-12 scores justifying the procedure.
Lumbar discectomy improved function and decreased pain level to similar extent in both younger and older patients suffering from radicular symptoms related to lumbar disc herniation.

Tranexamic acid can decrease blood loss related to surgery and trauma. The primary objective of this study is to examine if the use of a single dose of peri-operative TXA significantly decreases the rate of allogenic blood transfusions in the setting of operative care of hip fractures. Secondary objectives included examining if total blood loss was decreased by TXA in operative hip fractures as well as examining the safety of TXA by measuring the rates venous thromboembolism (VTE).
Retrospective chart review of 505 patients who were operatively treated for hip fractures at a single facility was performed. In a non-randomized fashion, 307 patients received TXA and 198 patients did not. Patients received 1gram of TXA prior to incision. Blood transfusion was the primary end point. Blood loss was calculated using the hemoglobin balance method. Chart was reviewed for VTE events during hospitalization.
505 patients were analyzed. The use of single perioperative dose of TXA in the surgical management of hip fracture resulted in absolute risk reduction of transfusion of 7.7% and relative risk reduction of transfusion by 29%. This was statistically significant with
=.04. Patients who received TXA on average lost 235ml less blood compared to those who did not receive TXA (
<.0001). No increase in VTE events were found in either group during hospitalization.
This study supports the use of TXA is decrease blood loss and transfusion rates in patients with hip fractures. TXA can be used routinely to decrease complications in this usually fragile population.

Geriatric patients with hip fractures often experience unexpected falls and they may have unfamiliar and unpleasant experiences within a brief period. This study aimed to investigate the prevalence and levels of preoperative anxiety in patients undergoing surgical treatment for hip fractures, and to determine the anxiety-related characteristics experienced by patients during the period before and after surgery.
We recruited a total of 75 geriatric patients who underwent surgical treatment for hip fractures and returned complete questionnaires. We used the State-Trait Anxiety Inventory (STAI)-X type to measure state-anxiety and defined a total score of 52 or higher as clinically meaningful state-anxiety. And, we investigated main cause of anxiety, moment of the highest level of anxiety, and the most helpful factor in overcoming anxiety before surgery and in reducing anxiety after surgery.
The mean STAI score was 47.2 points and one-third of the patients experienced various levels of clinically meaningful state-anxiety. The most common cause of preoperative anxiety was the surgery itself and patients experienced the greatest level of anxiety from the night preceding the surgery to the day of the surgery. Further, patients' trust in the medical staff prior to surgery and the surgeon's explanation after the surgery were the most key factors in overcoming anxiety.
This study investigates the state-anxiety of geriatric patients undergoing surgery for hip fractures and presents important findings which can help in developing evidence-based interventions to improve the experience of patients undergoing hip surgeries.

Juvenile myasthenia gravis accounts for 10-15% of all cases of myasthenia gravis. The clinical presentation of juvenile myasthenia gravis varies tremendously, which presents itself as a diagnostic challenge for clinicians. We report a case of a 15-year-old female with mild intermittent asthma presenting with shortness of breath. Acute onset of dyspnea is a common chief complaint amongst the pediatric population with a broad differential diagnosis. Our patient was presumptively treated for status asthmaticus and required invasive mechanical ventilation. After extubating, the patient showed persistent ptosis, which led to the eventual work-up of myasthenia gravis. Upon further review, this patient had months of intermittent symptoms including ptosis and fatigue which went previously undiagnosed. This case demonstrates that dyspnea in an asthmatic can occur from nonairway processes and, if missed, may result in overtreatment of asthma or delayed diagnosis of an important neuromuscular process.Myasthenia gravis is a neuromuscular autoimmune disease that results in skeletal muscle weakness that worsens after periods of activity and improves after rest. Myasthenia gravis means "grave (serious), muscle weakness." Although not completely curable, it can be managed well with a relatively high quality of life and expectancy. In myasthenia gravis, antibodies against the acetylcholine receptors at the neuromuscular junction interfere with regular muscular contraction. Although most commonly caused by antibodies to the acetylcholine receptor, antibodies against MuSK (muscle-specific kinase) protein can also weaken transmission at the neuromuscular junction. Muscle-specific tyrosine kinase myasthenia gravis (MuSK-Ab MG) is a rare subtype of myasthenia gravis with distinct pathogenesis and unique clinical features. Diagnosis can be challenging due to its atypical presentation as compared to seropositive myasthenia gravis. It responds inconsistently to steroids, but plasma exchange and immunosuppressive therapies have shown promising results.
