Diagnosis and management of liver abscesses in low- and middle-income countries (LMICs) is difficult due to limited diagnostic imaging availability. Limited data is available describing the use of point-of-care ultrasound (POCUS) in the diagnosis and percutaneous aspiration of liver abscesses in resource-limited countries. We describe a 21-year-old female who was diagnosed with a liver abscess. The diagnosis of liver abscess was made via POCUS, and the patient was successfully managed with empiric antimicrobials and repeated POCUS-assisted percutaneous needle aspiration. In resource-limited settings, adequate training of personnel and availability of POCUS may help in early diagnosis and treatment of liver abscess - thus helping to reduce its related morbidity and mortality - while also aiding in resource conservation.

We describe a rare and remarkable transformation of an immature mediastinal teratoma into high-grade angiosarcoma in a 21-year-old male. Mediastinal teratomas, particularly immature ones, are exceedingly rare, representing a small fraction of germ cell tumors (GCTs). Our case describes the clinical journey of the patient, who initially presented with acute chest pain and was subsequently diagnosed with an immature teratoma following imaging studies and elevated tumor markers. Despite an initial positive response to cisplatin-based chemotherapy, surveillance imaging revealed liver masses, which a biopsy confirmed as angiosarcoma. This transformation underscores the aggressive nature of immature teratomas and the propensity for sarcomatous differentiation, particularly in the mediastinum. The case contributes valuable insight into the management and surveillance of mediastinal non-seminoma germ cell tumors (MNGCT), a subset of GCTs with limited literature. We believe this case is the first in the literature to describe a transformation from an immature teratoma in the mediastinum to a high-grade angiosarcoma.

Stroke mimics are difficult to differentiate from each other. Symptomatic epilepsy can also occur, but it is necessary to perform a magnetic resonance imaging (MRI) scan to distinguish it from a stroke. Although respiratory acidosis has been reported to occur with partial-onset seizures due to prolonged apnea, respiratory acidosis is rarely suspected to be a sign of epilepsy. We report a case in which respiratory acidosis helped to diagnose symptomatic epilepsy with stroke mimics. The patient was a 52-year-old female who was brought to the emergency room with the chief complaint of difficulty in talking. When she visited the hospital, sensory aphasia was observed, and a computed tomography (CT) scan was performed. She vomited after the CT scan, and an arterial blood gas analysis showed a pH of 7.26 with a PaCO2 level of 71 mmHg, indicating respiratory acidosis. After the administration of diazepam, the seizures abated and her sensory aphasia improved. Later, an investigation of the patient\'s history revealed symptomatic epilepsy and discontinuation of antiepileptic drugs. If unexplained respiratory acidosis is noted in a patient with stroke mimics, a further investigation of the patient\'s history and physical examination may help to diagnose symptomatic epilepsy.

There are increasing reports of the effects of COVID-19 on the pancreas. Pancreatitis, as a result of hypertriglyceridemia, has also been reported. Hypothesized mechanisms include hemophagocytic lymphohistiocytosis (HLH) syndrome and acquired lipoprotein lipase (LPL) inhibitors. We present a 51-year-old female patient who presented with nausea, vomiting, and epigastric abdominal pain radiating to the back. On examination, she had generalized abdominal tenderness without guarding or rebound tenderness. Our workup revealed elevated lipase of 1150 units/L, triglycerides (TG) of 11340 mg/dL, and mild pancreatitis on an abdominal computed tomography (CT) scan. On day 2, she developed a new oxygen requirement and tested positive for COVID-19. She was treated with fluids and opiates for pancreatitis, plasmapheresis, and an insulin infusion to treat her hypertriglyceridemia. She was treated with remdesivir for an acute COVID-19 infection. Triglycerides decreased to <500 mg/dL with treatment, and she was discharged home on oral lipid-lowering agents. By discussing this case, we aim to shed light on the association between COVID-19 and hypertriglyceridemia, which can further lead to life-threatening complications such as acute pancreatitis. Further studies are needed to identify the exact mechanisms, preventive measures, and long-term effects of COVID-19 on triglycerides and the pancreas.

Lipomas are benign soft tissue tumors that are ubiquitous in nature. Available literature suggests that benign tumors are harmless unless they increase in size, resulting in compression of vital structures. This case report discusses the case of a 52-year-old man who presented to the clinic with a painless, growing lump on the right side of his mouth. The patient\'s symptoms included difficulty swallowing and speaking, which led the doctors to recommend surgical excision of the mass. There were no issues during the mass removal surgery, and the incision healed without compromising the lingual or hypoglossal nerves or Wharton\'s duct, as observed during follow-up visits. Patient history, symptoms, preoperative examination, treatment strategy, and surgical technique are all included in this case study, which focuses on the extremely unusual development of lipomas in the oral cavity, particularly on the floor of the mouth.

Cerebral arteriovenous malformations (cAVMs) are developmental pathologic lesions of the blood vessels of the brain in which multiple arteries shunt blood directly into the venous drainage network. They are lesions with an unclear etiology and, if left untreated, can bear significant risks of complications such as migraines, seizures, neurological deficits, and intracranial hemorrhages. The diagnosis is based on several imaging methods, with angiography being the primary method. Treatment modalities include microsurgery, radiosurgery, embolization with the intent of obliteration, and various multidisciplinary approaches. We aim to introduce the case of an adult female patient with symptomatic cAVM who underwent partial endovascular embolization of the lesion and evaluate her recovery and the overall reliability of her treatment modality. A 22-year-old female patient has presented to the Neurosurgery Clinic with clinical manifestations with photosensitive seizures, migraines, and a history of sleep disturbances persisting for a period of one year. An appointed MRI and angiography revealed the presence of a glomerular cAVM of the anterior parietal branch of the middle cerebral artery located within the intraparietal sulcus of the left cerebral hemisphere (Spetzler-Martin grade 2). The venous drainage of the malformation led to a loss of nutrients in the surrounding brain parenchyma (a steal phenomenon), causing the seizures. The patient successfully underwent transarterial endovascular embolization with Onyx, which proved to be partial on a postoperative angiography, and refused further embolization procedures. There were no postoperative complications to be mentioned. The patient reported no seizures or sleep disturbances at the 12-month follow-up, with sporadic weak headaches remaining. cAVMs remain a pathology with significant morbidity and mortality when undiagnosed. Symptomatic cAVMs leading to a steal phenomenon and seizures can be reliably managed via endovascular embolization alone when the malformation has an appropriate angioarchitecture, location, size, and a low Spetzler-Martin score. However, further inquiry is required into the use of partial embolization in cases where further multiple-stage embolization procedures are declined and/or complete occlusion of the lesion is unfeasible. This case report emphasizes that partial endovascular embolization can be successfully utilized as a treatment modality for the symptoms caused by a steal phenomenon of the venous drainage of a cAVM, such as seizure disorders and migraines, in the rare instance when multiple-stage embolization is declined by the patient and occlusion of the lesion remains subtotal.

Perineural cysts, also known as Tarlov cysts, are rare benign cerebrospinal fluid-filled cysts usually located at the junction of the posterior nerve root and the dorsal root ganglion and are usually asymptomatic. They are most commonly found in the sacral region and are uncommon in the cervical spine. Despite their rarity, symptomatic cases may present with neurological symptoms due to the compression of adjacent neurological structures. Symptomatic cervical perineural cysts are extremely rare, and there is limited consensus on management strategies. We present the case of a 56-year-old woman who presented with a four-week history of radicular symptoms involving the right C7 and C8 nerve roots, including neck and arm pain, paresthesias, and mild triceps weakness. Magnetic resonance imaging revealed two perineural cysts at the C6-C7 and C7-T1 levels. A conservative approach was chosen with a 14-day course of oral corticosteroids, use of a soft collar, and activity restrictions. Following this conservative treatment, a significant reduction in symptoms and complete neurological recovery were achieved. This case highlights the efficacy of conservative approaches in selected cases of mildly symptomatic cervical perineural cysts and contributes to a better understanding of management strategies for this condition.

Aim The aim of this study is to evaluate the impact of the Preferred Reporting Items for Case reports in Endodontics (PRICE) 2020 guideline on the reporting of published endodontic case reports (CRs). Methodology All case reports published in the International Endodontic Journal, European Endodontic Journal, Journal of Endodontics and Restorative Dentistry and Endodontics, in the year before and after the release of PRICE 2020, were included for analysis. Two panels comprising dentists scored case reports against a scoring system adapted from the guideline. Individual items were scored up to a maximum of 1; scores were then summated to provide an overall maximum of 47 for each CR. Each report provided an overall percentage adherence, and panel agreement was calculated using the intraclass correlation coefficient (ICC). Disagreement on scoring was discussed until a consensus was reached. Scores before and after PRICE guideline publication were compared using an unpaired two-tailed t test. Results A total 19 CRs were identified in both the pre- and post-PRICE guideline publication. Mean adherence to PRICE 2020 increased by 7.9% (p=0.003) from 70.0%±8.89 to 77.9%±6.23 following its publication. Agreement between panels was moderate (ICC pre-PRICE: 0.673 {p=0.011}; ICC post-PRICE: 0.742 {p=0.003}). Items 1a, 6c, 6e, 6f, 6g, 6j, 6q, 6s, 7a, 9a, 11a, 12c and 12d experienced a fall in compliance. Conclusion The PRICE 2020 guideline has resulted in a modest improvement in the reporting of endodontic case reports. Greater awareness and a wider acceptance and implementation of the guideline in endodontic journals are needed to improve adherence to the novel guideline.

BACKGROUND: The occurrence of obstructive and central sleep apnea syndromes, ventilator pump failure and reduced hypercapnic ventilatory drive in myotonic dystrophy type 1 (DM1) is well established, and there are indications for an impairment of the hypoxic ventilator drive, too. Yet, it is still unknown, to which extent the respiratory rhythm is affected by DM1, thus if a central bradypnea, cluster breathing or ataxic (\"Biot\'s\") breathing can occur. Additionally, the causes of the impairment of the central respiratory drive in DM1 are not known.
METHODS: We present the case of a tracheotomized female patient with DM1 with central bradypnea and ataxic breathing. A 57-year-old woman with DM1 was admitted to our Neurointensive Care Unit (NICU) due to refractory tracheobronchial retention of secretions resulting from aspiration of saliva. Due to a combination of chronic hypercapnic respiratory failure, severe central bradypnea with a minimal breathing frequency of 3 per minute and ataxic breathing a pressure-controlled home ventilation was initiated.
CONCLUSIONS: In our patient central bradypnea and ataxic breathing possibly were respiratory sequale of DM1, that may have been caused by pontine white matter lesions affecting the pontine respiratory nuclei. From a clinical viewpoint, polygraphy is a suitable tool to objectify disorders of the respiratory rhythm in DM1 even in tracheotomized patients. Clinical studies combining respiratory diagnostics as polygraphy, transcutaneous capnometry and blood gas analysis with brain magnetic resonance imaging (MRI) are required to better understand disorders of respiratory regulation in DM1, and to identify their anatomical correlates.

We describe clinical presentation of Wolfram syndrome and follow-up data in a child. Diagnostics of Wolfram syndrome takes time because clinical symptoms develop not at the time of disease manifestation, but usually several years later. The sequence of manifestations also varies. According to the literature, sensorineural hearing loss occurs in the 2nd decade, and bladder atony develops only by the 3rd decade. In the presented case, initial manifestations of bladder innervation disorders in the form of its dysfunction developed as early as the first year, and sensorineural hearing loss formed by the 4th year of the disease. As in other studies, the patient developed optic disc atrophy within the first year after diabetes onset. This clinical case confirms variability in the clinical symptoms of Wolfram syndrome. The sequence in which the disease picture develops (in this case, there was an incomplete form of syndrome - the absence of diabetes insipidus) does not always coincide with the classic course of syndrome, which complicates timely diagnosis.
Описаны клиническая картина синдрома Вольфрама у ребенка и данные динамического наблюдения за больным. Диагностика синдрома Вольфрама требует времени, поскольку клинические симптомы проявляются не в момент манифестации заболевания, а, как правило, лишь через несколько лет. Этапность проявлений также варьирует. По данным литературы, нейросенсорная тугоухость отмечается во 2-м десятилетии, а атония мочевого пузыря развивается только к 3-му десятилетию. В данном случае начальные проявления нарушения иннервации мочевого пузыря в виде его дисфункции проявились уже на 1-м году, а нейросенсорная тугоухость сформировалась к 4-му году заболевания. Атрофия диска зрительного нерва у пациента развилась, как и в других исследованиях, в течение 1-го года после начала сахарного диабета. Данный клинический случай подтверждает вариабельность клинической симптоматики синдрома Вольфрама. Последовательность развития всей картины заболевания (в данном случае имеет место неполная форма синдрома — отсутствие несахарного диабета) не всегда совпадает с классическим течением синдрома, что затрудняет своевременную диагностику.
