Background: Worldwide, there is an increase in the frequency of reports of psoas abscesses due to advances in imaging technology, which has led to early diagnosis and treatment. A bilateral psoas abscess is rare and, when it occurs, is usually secondary and in immunocompromised patients. We present a case of a bilateral tuberculosis psoas abscess in a human immunodeficiency virus-positive patient.

Case presentation: A 21-year-old Ugandan female undergraduate who contracted human immunodeficiency virus through vertical transmission and has been on highly active antiretroviral drugs presented with bilateral lower abdominal pain with associated fever and headache. Clinical examination revealed abdominal tenderness in both iliac fossae with palpable masses. Ultrasonography revealed fluid collection in both psoas muscles confirming bilateral abscesses. The aspirate was acid-fast bacilli positive. A diagnosis of bilateral tuberculosis psoas abscess was made. Open drainage was performed and antituberculosis drugs were commenced.

Conclusions: Bilateral tuberculosis psoas abscesses occurring in human immunodeficiency virus-positive patients, although uncommon, is not unexpected. It is a form of secondary psoas abscess in immunocompromised patients. Here, the outcome was successful with a combination of early surgical drainage and appropriate medical therapy.

Background: Pinworm, Enterobius vermicularis, is a common parasitic illness, particularly among children in Palestine. On rare occasions, it can cause serious consequences such as acute appendicitis, which can still present a challenging diagnosis especially in children.

Case presentation: This report describes two cases (a 9 year old male and a 11 year old female, both Palestinian children from Hebron district) of acute appendicitis referred to Queen Alia Hebron Governmental Hospital in Palestine. The clinical examination revealed a lower abdominal pain, and they were diagnosed with appendicitis. The pathological examination after appendectomy showed the presence of eggs and pinworms. Anthelminthic medication was provided, and they were followed up for 6 weeks after the operation without any incidents.

Conclusion: These cases highlight the importance of considering Enterobius vermicularis infestation in children with abdominal pain, as the parasites can mimic appendicitis. Prompt recognition and cautious laparoscopic appendectomy are crucial to prevent unnecessary surgery and peritoneal contamination, with the infestation being easily treatable with anthelmintic medication.

Background: Spontaneous hepatic hemorrhage is a rare condition, most commonly diagnosed in patients with hepatocellular carcinoma or hepatic adenomas, and is seldom caused by metastatic disease. In this case report, we present a patient with spontaneous hepatic hemorrhage due to hepatic metastasis of papillary thyroid carcinoma, an exceptionally rare occurrence.

Case presentation: The patient was a 77-year-old white male with a history of atrial fibrillation treated with apixaban. He presented at a local hospital with abdominal pain and nausea. A CT scan revealed a hepatic lesion in segment 3 with an adjacent hematoma. He was referred to our tertiary center and treated conservatively. Further evaluation revealed an intrathoracic goiter containing a tumorous process diagnosed as a papillary thyroid carcinoma (PTC), and the patient subsequently underwent thyroidectomy. A biopsy of the hepatic lesion confirmed it as a PTC metastasis. Due to worsening abdominal pain and anorexia, the patient underwent subacute hepatic segmental resection. Postoperatively, he developed iodine-refractory disease with disseminated metastasis and passed away 22 months after the initial admission.

Conclusions: To our knowledge, this is the first recorded case of metastasized papillary thyroid carcinoma presenting with spontaneous hepatic hemorrhage-adding to the list of rare causes for this condition.

Background: Intestinal duplication cyst is an infrequent congenital malformation that can involve all the segments of the gastrointestinal tract. The cases of intestinal duplication cyst involving the colon, appendix, and ileum in children are particularly uncommon. The symptoms of abdominal pain are similar to other acute abdominal diseases in children, such as appendicitis, intussusception, and intestinal obstruction, so sometimes its diagnosis is challenging and leads to misdiagnosis.

Case presentation: We report a 4-year-old Asian boy who presented to the pediatric emergency department with abdominal pain and vomiting but no fever, peritonitis, or mass. No abdominal abnormality was found via radiology and ultrasonography. After 2 days' anti-inflammatory therapy, the patient was discharged with pain relief. A total of 9 months later, he was readmitted to the pediatric emergency department for the same complaint as the first admission. Abdominal physical examination and ultrasound examination were still negative. Barium examination found a large mass in the colon. Colonoscopy was performed before operation to confirm the rare co-cavity intestinal duplication cyst involving the colon, appendix, and ileum. After resection of intestinal duplication and ileocolonic anastomosis, the patient's abdominal pain and vomiting has not recurred for 5 years postoperatively.

Conclusions: The diagnosis of intestinal duplication cyst in children is difficult, especially the rare co-cavity and long segmental intestinal duplication, which is easily misdiagnosed. Colonoscopy may be an effective auxiliary diagnostic method, especially for diseases that are difficult to diagnosed clinically, such as recurrent abdominal pain.

Background: Peritoneal dialysis as one of the nephrology services in children with acute kidney injury is a safe and cost-effective modality of treatment in low and lower-middle income countries. Despite evidence of its effectiveness in limited resource settings, the service is still provided only in tertiary level healthcare facilities in Tanzania.

Case presentation: In this case report, we narrate the survival of a 22-month-old male patient of African descent with an acute kidney injury following a swarm of bees' stings at home. A lifesaving, although low-quality and high-risk, peritoneal dialysis was performed for 5 days at Iringa Regional Referral Hospital, a secondary level health facility in rural Tanzania with lack of standard and recommended expertise, laboratory investigations, and equipment.

Conclusion: Lower- and middle-income countries in collaboration with stake holders should ensure that this service is available, accessible, and safe in the lower-level health facilities, given that access to the tertiary-level facilities is inadequate and time limited, hence serving a larger population.

Background: Bacterial pneumonia is one of the most common causes of acute respiratory distress syndrome. In fulminant cases, when mechanical ventilation fails, veno-venous extracorporeal membrane oxygenation is required. However, this method is still associated with significant mortality and a wide range of potential complications. However, there are now many case reports of good outcomes even in patients with prolonged extracorporeal oxygenation, as in our rather complicated case report.

Case presentation: Our case report describes a complicated but successful treatment of a severe, devastating bacterial pneumonia in a 39-year-old European polymorbid woman with a rare form of diabetes mellitus, which had been poorly compensated for a long time with limited compliance, in the context of a combined immunodeficiency that strongly influenced the course of the disease. The patient's hospitalization required a total of 30 days of veno-venous extracorporeal membrane oxygenation therapy and more than 50 days of mechanical ventilation. Numerous complications, particularly bleeding, required seven chest drains, two extracorporeal membrane oxygenation circuit changes, and one surgical revision. The patient's mental state required repeated psychiatric intervention.

Conclusion: It is possible that even the initially severely damaged lung parenchyma can develop its regenerative potential if suitable conditions are provided for this process, including a sufficiently long period of extracorporeal membrane oxygenation. We believe that this case report may also contribute to the consideration of the indications and contraindications of extracorporeal support. The authors also discuss the limitations and risks of prolonged veno-venous extracorporeal membrane oxygenation support and periprocedural anticoagulation strategies.

Introduction: Neonatal myiasis is a rare condition, with few reports available on the subject. Surgical management is recommended in some cases. In this study, we present the case of a 7-day-old male neonate with larvae in his scrotum who underwent surgery.

Case presentation: A full-term 7-day-old male infant (Aryan race) was referred to a children's hospital. On the sixth day after birth, three 3-4 mm long larvae crawled out from his scrotum, with the number increasing over time. He was given intravenous antibiotics and topical mupirocin to combat secondary infections. The surgical treatment involved two steps: first, the larvae were extracted, and then the infection site was washed with betadine and hydrogen peroxide to help remove any possible remaining larvae.

Conclusion: Scrotal myiasis is a rare disease that occurs in infants and requires immediate treatment. Surgical treatment is effective in removing dead or decaying larvae from a deep-seated location and washing the infection site to prevent secondary infection.

Introduction: Coronary cameral fistulas (CCFs) are rare congenital anomalies characterized by abnormal connections between a coronary artery and one of the cardiac chambers. These abnormal connections can lead to significant clinical implications, including heart failure and myocardial ischemia, necessitating timely diagnosis and intervention.

Case presentation: A 5-year-old Iranian boy was brought to the emergency room at Heart Hospital Center complaining of chest pain and dyspnea on exertion. He had experienced similar episodes over the past 4 months, which had not been evaluated. Physical examination revealed stable vital signs and no remarkable findings. Transthoracic echocardiography demonstrated a dilated left coronary artery with a large aneurysm and a small orifice to the right ventricular body. The left ventricular ejection fraction was 55%. Cardiac computed tomography angiography confirmed the diagnosis. Cardiac angiography showed a dilated left coronary artery and a coronary cameral fistula to the right ventricular . The aneurysm was successfully occluded using two Amplatzer™ devices.

Conclusion: This case underscores the critical role of multimodal imaging in diagnosing and managing coronary cameral fistulae. Early detection and appropriate intervention are paramount in preventing the progression of symptoms and potential complications such as heart failure and myocardial ischemia. The successful closure with Amplatzer™ devices highlights the efficacy of minimally invasive techniques in treating complex cardiovascular anomalies. Regular follow-up and careful monitoring are essential to ensure long-term success and to manage any potential recurrences.

Clinical key message: Timely identification and management of coronary cameral fistulae are crucial to prevent complications. Advances in imaging techniques and minimally invasive treatments, such as transcatheter closure, offer effective solutions. A multidisciplinary approach and regular follow-up are essential for comprehensive care and successful long-term management.

Background: Immunoglobulin light-chain amyloidosis is a relatively rare condition with a worldwide incidence of 5.1-12.8 cases per million person-years (Baker, 2022). It is characterized by a clonal population of immunoglobulin-secreting cells that produce a monoclonal light chain of κ or λ type as either an intact molecule or a fragment.

Case presentation: A 69-year-old East Asian (Chinese) male patient who presented with progressive dysphagia visited multiple hospitals repeatedly for more than 2 years and was finally diagnosed with immunoglobulin light-chain amyloidosis.

Conclusions: Otolaryngologists should consider immunoglobulin light-chain amyloidosis when encountering suspicious clinical manifestations and intervene early to avoid misdiagnosis.
