A Case Report on Anti-N-Methyl-D-Aspartate Encephalitis

Aim: The case study aims to describe and evaluate the initial neuropsychiatric symptoms, therapeutic methods, and diagnostic criteria, of a 3-year-old girl who had been diagnosed with anti-N-Methyl-D-Aspartate Receptor (NMDAR) encephalitis. This case study implies the importance of early detection and treatment in pediatric autoimmune encephalitis, highlighting its diagnostic challenges and the successive use of immunotherapy and outcomes. Presentation of Case: A 3-year-old developmentally normal girl child was brought to the hospital with C/O fever for 2 days. Following this she had seizures lasting for around 2 minutes and followed by shivering movements in the right leg for 15 minutes and then she regained consciousness after 25 minutes. CSF analysis showed pleocytosis. Serological tests (Typhoid IgM, Rapid Malaria, Scrub IgM, Dengue IgM, Japanese Encephalitis, and Herpes Simplex Virus IgM) were negative. MRI indicated diffuse encephalopathy, and EEG detected epileptic activity. Further antibody testing in serum and CSF revealed positive Anti-NMDAR antibodies. The patient was treated with amoxicillin-clavulanate(400mg), ceftriaxone(750mg), and acyclovir(130mg) intravenously initially. Once the definitive diagnosis was made, she was treated with IVIG(26g), methylprednisolone(390mg), and levetiracetam(280mg). Discussion: Anti-N-Methyl-D-Aspartate Receptor Encephalitis is an autoimmune encephalitis characterized by complicated neuropsychiatric symptoms and immunoglobulin G (IgG) antibodies against the NR1 subunit of the NMDA receptors in the central nervous system. Conclusion: The appropriate diagnosis and treatment of autoimmune encephalitis necessitate an organized approach. A wide range of autoantibody tests can be performed to identify or rule-out specific autoimmune causes. Patients may relapse and require appropriate follow-up care.

The impact of alcohol misuse in trauma patients: A scoping review protocol.

Alcohol use is a contributing factor in many cases of traumatic injury. There is conflicting evidence on the impact of alcohol use at the time of physical trauma on severity of injury and hospital course. Similarly, the significance of alcohol use disorder on outcomes in hospitalized trauma patients is unclear. This scoping review aims to provide a concise overview of the current literature surrounding peri-trauma alcohol use and alcohol use disorder on injury severity, in-hospital complications, patient outcomes, and long-term health impact of alcohol use in trauma. We will also explore the associated healthcare costs of this patient population. A systematic search of the following databases MEDLINE, EMBASE, and Cochrane Library will be completed to extract all studies that meet our inclusion criteria from January 2000 onwards. Case reports will be excluded. Two reviewers will screen all citations, abstracts, and full text articles. A third reviewer will act as tiebreaker at each stage of the screening process. A narrative synthesis without meta-analysis will be conducted and assessed based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) guidelines. This review will contribute to the literature by providing a concise overview of the current data on the impact of alcohol on outcomes following trauma. We will explore the overall themes in the literature, limitations, and future directions to focus forthcoming research in this patient population. This project is registered via the Open Science Framework. The public registration is uniquely identified with the following DOI: https://doi.org/10.17605/OSF.IO/Z84WK.

A case report of intrapulmonary mature teratoma with aspergilloma

Introduction: Teratomas are benign germ cell tumors composed of components from the ectoderm, mesoderm, and endoderm. While germ cell tumors account for 10-20% of anterior mediastinal masses, intrapulmonary teratomas (IPTs) are extremely rare. They typically occur in the third decade of life and may present as metastasis from gonadal tumors. This study reports a rare case of a mature IPT in the right middle lobe of the lung, initially misdiagnosed as pulmonary tuberculosis and aspergilloma. Case Presentation: A 17-year-old female presented with a 4-year history of cough with sputum and two episodes of hemoptysis. Despite negative tuberculosis tests, she was treated with anti-tubercular drugs and multiple antibiotics. Imaging revealed a 5.5-cm cavitary mass in the right middle lobe containing an aspergilloma. Surgical resection was performed, and the pathology confirmed a mature teratoma with aspergilloma colonization. The patient recovered well postoperatively and showed no signs of recurrence. Discussion: Teratomas are germ cell tumors rarely found in the lungs, with fewer than 100 cases reported globally. Diagnosis is challenging due to overlapping symptoms with other conditions such as tuberculosis. In this case, the presence of an aspergilloma further complicated the diagnosis. Complete surgical resection led to the patient's recovery. Conclusion: Mature IPTs with aspergilloma are extremely rare, and should be considered in the differential diagnosis of cavitary lung lesions. Early diagnosis and surgical resection are crucial for successful treatment.

Chronic myelogenous leukemia: a case report from Azal Hospital, Sana'a, Yemen

Chronic myelogenous leukemia (CML) is a myeloproliferative disorder that is always associated with the presence of the BCR-ABL gene. In this article, we report the case of a 38-year-old male patient who presented with fever, fatigue, abdominal pain, and blurred vision. Investigations confirmed CML with leukemic-like retinal hemorrhages and anemia. The patient was immediately given imatinib 400 mg daily for 2 weeks, and then hydroxyurea 500 mg daily was added. After 4 months, the white blood cells, hemoglobin, and basophils returned to normal values, the retinal hemorrhages improved, and the patient's general health improved.

Pressurized Intraperitoneal Aerosol Chemotherapy for Peritoneal Carcinomatosis in Colorectal Cancer Patients: A Systematic Review of the Evidence

Introduction: Pressurized intraperitoneal aerosol chemotherapy (PIPAC) consists of the administration of aerosolized chemotherapy into the abdominal cavity of patients suffering from peritoneal carcinomatosis. Our aim was to review the evidence supporting PIPAC in patients with peritoneal carcinomatosis from colorectal cancer. Methods: A systematic review was performed in accordance with the 2020 PRISMA guideline. MEDLINE and CENTRAL were searched using combinations of terms including “Peritoneal carcinomatosis”, “Peritoneal metastasis”, “PIPAC”, “Pressurized intraperitoneal aerosol chemotherapy” and “Colorectal cancer”. Original studies, in English, including patients treated with PIPAC for colorectal peritoneal carcinomatosis, were considered eligible. Case reports, non-English or French language articles and secondary analyses were excluded. Results: A total of 385 articles were screened and 374 articles were excluded, leaving 11 publications for inclusion in the qualitative analysis. The included studies totalized 949 patients who received PIPAC for peritoneal carcinomatosis due to colorectal cancer. The median peritoneal carcinomatosis index (PCI) ranged from 10 to 31. In all studies, the complete PIPAC protocol was achieved with an average of two to three 3 PIPAC sessions per patient. Oxaliplatin (OX) was used as a chemotherapeutic agent in all studies and could be associated with intravenous 5-FU and leucovorin. Most post-operative adverse events were recorded as mild to moderate with no intraoperative complications. Only four studies reported a decrease in the average PCI score for 50% of the patients. Median overall survival ranged from 8 to 37.8 months. Quality of life indicators were stable between PIPAC-OX cycles with a small but not statistically significant trend of improvement of most functional scales. Conclusions: PIPAC for peritoneal carcinomatosis from colorectal origin is feasible, safe and tolerable. Its impact on survival outcomes or quality of life remains to be demonstrated by randomized trials.

Immune Thrombocytopenia Following Dengue Fever

Introduction: Dengue is an endemic mosquito-borne infection in tropical countries. The manifestations vary from asymptomatic infection to classic dengue fever, to more critical forms like dengue hemorrhagic fever and dengue shock syndrome. The critical phase occurs typically within the timeline of 4-7 days from the onset of symptoms. Case Report: We, hereby, report the case of a 7-year-old girl child who initially recovered from classic dengue fever. However, she was readmitted 18 days after the onset of initial symptoms with major bleeding manifestations due to immune thrombocytopenia responding to intravenous immunoglobulin. Discussion: Dengue fever may be associated with mild to moderate thrombocytopenia in the febrile phase and moderate to severe thrombocytopenia in the critical phase. Here, the index case developed thrombocytopenia much after the expected critical phase was over. Conclusion: Awareness of this possibility and continued monitoring, even after apparent recovery from dengue, is important for detecting and managing late-onset thrombocytopenia.

Reperfusion injury case following cervical fusion with OPLL: a case report and literature review

IntroductionSpinal cord ischemic reperfusion injury is characterized by an abrupt decline in neurological function and only a few cases have been published in literature. Herein, we present a white cord syndrome following anterior decompression cervical fusion.Case ReportA 54-year-old Jewish male patient was diagnosed with disc herniation among the intervertebral discs at C2, C3, C4, C6, and C7, along with ossification of the posterior longitudinal ligament, pressuring more to the right side of the spinal canal, ruling-out cervical myelopathy. Under general anesthesia and multimodal intraoperative monitoring, he underwent laminectomy surgery from C3 to C6 and cervical fixation from C3 to C7. No blood pressure fluctuations occurred during surgery, and complete pressure release was achieved on the spinal cord and the nerve roots. In addition, neuromonitoring did not indicate any nerve damage during the surgery. A neurologic exam in the post-anesthesia care unit revealed weakness in his right hand and leg. A brain computed tomography scan ruled out cerebrovascular accident, neck computed tomography revealed optimal implant position, and magnetic resonance imaging ruled out spinal cord distress or injury. We treated him with intravenous fluids, steroids, painkillers, and anticoagulants. Following surgery, we involved the occupational therapy department. After a few days, we observed a significant improvement in motor function in the right leg; however, there was no change in the right hand.ConclusionWhite cord syndrome likely arises from reperfusion injury subsequent to surgical decompression of a compressed spinal cord segment. Although infrequent, it is imperative for spine surgeons to recognize this potential complication and apprise patients of it prior to the procedure.

Case Report: Ocular paroxysmal non-epileptic events as the presenting sign of celiac disease in children: a case series

IntroductionNeurologic manifestations may be presenting signs of celiac disease (CD). Pediatric-onset paroxysmal non-epileptic events (PNEEs) are not included among them.Cases presentationWe report the case of two children who presented with ocular PNEEs in association with mild symptoms evocative for CD, who were subsequently diagnosed with CD and experienced regression of PNEEs on a gluten-free diet. Data from 12 patients undergoing neurological evaluation in 2019–2023 for ocular PNEEs were reviewed: 3 (25%) had a subsequent diagnosis of CD.ConclusionsOcular PNEEs could be a presenting manifestation of CD. In the diagnostic work-up of PNEEs, screening for CD could be included, both to avoid unnecessary tests and to promptly start a gluten-free diet, which might lead to a favorable clinical response.

Ultrasound-guided injection using leucocyte-rich platelet-rich plasma for treatment of meniscal injuries in a duathlete: a case report.

There is a paucity of data regarding using platelet-rich plasma therapy for Baker's cyst-associated medial meniscal tear. To date, conservative treatments for this type of condition include aspiration of fluid effusion with steroid injection and physical therapy. When this treatment fails, arthroscopic debridement, meniscectomy, cyst decompression and open cystectomy are available surgical management options. Recurrence rates, however, are high such that even these procedures fail to provide long-term pain relief. This case study explores the benefits of leukocyte-rich platelet-rich plasma therapy in treating tears in the posterior horn of the medial meniscus with concomitant Baker's cyst. With limited studies available, this case hopes to encourage more studies to be done in the future to provide a conservative option for patients with similar cases.

Epithelioid (Histiocytoid) hemangioma of the testis: A case report and literature review of a rare benign tumor.

Testicular hemangioma is a rare benign vascular neoplasm originating from the inner layer of the tunica albuginea, predominantly affecting the pediatric population and often associated with hemangiomas in other organs. Histopathologically can be categorized into four types, including capillary, cavernous, papillary endothelial hyperplasia, and epithelioid (histiocytoid). We report a case of a 24-year-old presenting with left inguinal pain, diagnosed with an epithelioid (histiocytoid) hemangioma of the testis. Diagnostic evaluation included scrotal doppler ultrasonography, which revealed a small, hypoechoic formation with evident vascularization. Serum tumor markers were within normal limits. Surgical excision via testis-sparing surgery (TSS) was performed based on frozen section analysis. A literature review underscores the rarity of testicular histiocytoid hemangiomas. Advancements in diagnostic technique have improved the accuracy of diagnosis and allowed for more conservative surgical approaches, preserving fertility and minimizing long-term adverse effects. In conclusion, while testicular hemangiomas may present characteristic features on ultrasound, frozen section examination remains crucial in guiding surgical decision-making. TSS offers significant advantages over traditional excisional surgery, including reduced morbidity and preservation of cancer control, making it an essential option in the management of testicular hemangiomas, particularly in young patients concerned about fertility preservation.

Pulmonary metastases revealing a mixed germ cell tumor with a predominant yolk sac tumor component: A case report

Yolk sac tumor of the testis is rare in adults. Its diagnosis is histological, reproducing an extra-embryonic structure (endodermal sinus tissue). It can be present alone or associated with another component, thus forming a mixed germ cell tumor. Treatment involves orchiectomy and chemotherapy in extratesticular stages. Lymph node dissection is indicated if residual masses persist. These tumors are characterized by a poor prognosis at an advanced metastatic stage. However, we report the clinical case of a 69-year-old man who presented with pulmonary metastases from a mixed germ cell tumor of the testis with a predominant Yolk Sac Tumor component, treated by orchiectomy, chemotherapy, and lymph node dissection.

Clinical and Dermoscopic Characteristics of Cutaneous Chondroid Syringoma: A Systematic Review

Introduction: Cutaneous chondroid syringoma (CS) is a rare benign mixed skin tumor originating from sweat glands. Despite its rarity, accurate diagnosis and management are crucial due to its potential for malignant transformation. Objective: This study aims to provide comprehensive insights into the main features of cutaneous CS, encompassing its epidemiology, clinical presentation, and particularly, dermoscopic findings. Methods: A systematic review was conducted to identify relevant literature on CS up to November 2023. Data extraction included clinical and histopathological characteristics from case reports and small case series. Results: The systematic review identified 347 unique CS cases, predominantly benign. Clinical features included a predilection for the head and neck region, with variations in morphology observed. Dermoscopic patterns, although limited, revealed recurrent features aiding diagnosis. Malignant CS cases constituted a notable subset, exhibiting distinct clinical and histopathological features. Conclusion: Cutaneous chondroid syringoma presents with characteristic clinical and histopathological features, necessitating comprehensive diagnostic approaches. Dermoscopy emerges as a valuable tool, although further research is needed to establish definitive patterns. Treatment primarily involves wide local excision, with collaboration among clinicians essential for optimal management. Future studies are warranted to address existing knowledge gaps and enhance understanding of this rare skin neoplasm.

Dysphasia: metastatic prostate cancer to the leptomeninges: a case report

BackgroundLeptomeningeal metastasis occurs in 5% of patients with prostate cancer and indicates a very poor prognosis.Case presentationA 60-year-old Caucasian male patient diagnosed with metastatic castration-resistant prostate cancer with sclerotic bone metastases and soft tissue metastases underwent multiple courses of chemotherapy and hormone therapy. The diagnosis of prostate cancer is based on elevated prostate-specific antigen levels and tissue biopsy. He subsequently presented with expressive aphasia. Nonspecific, diffuse irregular dural/pachymeningeal thickening enhancement was noted on magnetic resonance imaging. Upon evaluation by neurology, electroencephalogram was negative for an epileptiform correlate. The workup included a lumbar puncture to rule out infectious etiology. The patient’s neurological status stabilized, and he was discharged home with a plan for continued therapy with abiraterone and prednisone. Due to advanced malignancy, the patient enrolled in hospice and died 3 weeks after hospital discharge.ConclusionsCentral nervous system metastasis occurs very rarely in prostate cancer. With the increase in life expectancy and advances in oncologic therapy for prostate cancer, physicians should be aware of and consider central nervous system metastasis in men aged 50 years and above.

Functional outcomes in anterior talofibular ligament repair with anchoring screw: Two case series

Background: The Anterior Talofibular Ligament (ATFL) functions to resist plantarflexion and anterolateral translation of the talus. Lateral ankle sprains account for 85% of all ankle sprains and are most common in athletes. ATFL injury is the most common ankle ligament injury, accounting for 35.6% of the total patients with ligament injuries. Case Report: The first patient, a 39 year old man with a diagnosis of ATFL injury, had a history of falling with the outside of his right leg supported when he fell. Physical examination of the right ankle revealed tenderness in the posterolateral region, pain during dorsiflexion and plantarflexion, positive anterior drawer examination and positive talar tilt. The second patient, a 19 year old male with the same history and injury location on the right ankle. Physical examination showed a similar condition to the first patient. MRI examination of both patients showed ATFL injury. Both patients underwent open repair of the right ATFL (Brostrom technique) with anchoring screws, post-operative care, and evaluation one year after surgery. Discussion: Surgery is taken to prevent repeated ruptures, especially in cases of ligament tears. The Brostrom technique is an anatomical repair with end-to-end repair from the final ATFL tear to the distal anterior fibula. Both patients demonstrated normal foot and ankle function, with a score of 100 based on the American Orthopedic Foot Ankle Association (AOFAS). Conclussion : Brostrom open repair with Anchoring Screw is an effective procedure in returning the patient's function to its previous level as assessed based on the AOFAS score after a year after surgery.

Novel association of LBX1 mutation with tetralogy of Fallot and hypertrophic cardiomyopathy: implications for cardiac development.

Tetralogy of Fallot (TOF) and hypertrophic cardiomyopathy (HCM) are common types of congenital heart disease with unique pathophysiologic features. Mutations in LBX1, a key regulator of muscle precursor cell migration, may disrupt these critical developmental processes, resulting in severe developmental abnormalities. This case reports on a 4-year-old girl diagnosed with both TOF and HCM. Genetic analysis revealed iUPI-F (uniparental disomy) on the entire chromosome 10, with a c.808G > A (p. Glu270Lys) pure mutation in the LBX1. This patient exhibited both TOF and HCM with mutations in the LBX1 gene, suggesting a potentially novel genetic link. This case study emphasizes the need for further studies on the function of the LBX1 gene in cardiac development and its potential impact on TOF and HCM.

Late complete atrioventricular block after transcatheter perimembranous ventricular septal defect closure with the KONAR-MF™ VSD occluder: a case report and systematic review.

The soft nitinol KONAR-MF™ ventricular septal defect (VSD) Multifunctional Occluder (MFO) device is increasingly used for transcatheter perimembranous ventricular septal defect closure. We report for the first time a case of delayed complete atrioventricular block with pacemaker implantation 20 months post-procedure. Through a systematic review, the overall rate of persistent complete atrioventricular block was 0.6% with this device, but follow-up duration was limited.

Bilateral hip ochronosis, an unsuspected diagnosis in polyarticular pain: A case report

Alkaptonuria is a rare metabolic disorder characterized by the accumulation of homogentisic acid, leading to the deposition of blackish pigment in cartilage and soft tissue, known as ochronosis. This can mimic multiple joint pathologies and is a diagnosis of exclusion. We describe the case of a 52-year-old woman who had a total hip replacement after experiencing left hip pain for which oral medications were unable to provide relief. Unexpectedly, during the procedure, a blackish tissue was noticed. This led to a histological examination and the confirmation of the ochronosis diagnosis. The patient’s medical history revealed a number of malignancies, but no previous metabolic illness diagnoses. Subsequent follow-up revealed rapid-onset pain in other joints, leading to a similar diagnosis of polyarticular ochronosis in the right hip, knees, spine, and shoulders. This highlights how difficult it is to treat this condition. This case underscores the importance of considering ochronosis as a differential diagnosis in patients with chronic polyarticular pain. Current treatment consists of initial non-surgical measures, including physical therapy and analgesics. If there is no improvement, treatment would be joint arthroplasty. Awareness among orthopedic surgeons and histopathological examination of tissues is crucial for the accurate diagnosis and management of ochronosis.
