RESUMEN
Hepatoblastoma is one of the most common primary malignant liver tumors in children. The incidence of hepatoblastoma has been increasing, reaching 1.2 per million children now. The transarterial chemoembolization (TACE) procedure is one of the most practical and effective treatment options besides surgery. Digital subtraction angiography (DSA) is performed as the first step of the TACE procedure. The aim of this study was to provide information about the feeding arteries and enhancement pattern of the hepatoblastoma that was assessed by DSA before the TACE procedure. A retrospective study was conducted among hepatoblastoma cases that had undergone DSA on the TACE procedure to obtain information on the vascularity of the tumor. A total of 26 hepatoblastoma cases who had DSA examination as a part of their first TACE procedure were included, consisting of 15 boys and 11 girls, aged between 1-15 years. All cases were stage III and IV according to the Pre-Treatment Extent of Tumor (PRETEXT) staging classification. All hepatoblastoma cases had multiple feeding arteries, most of which were branches of the right hepatic artery. The largest diameter of the feeding artery was 1.82 mm, and the smallest was 0.63 mm. Most cases (84.62%) had strong contrast absorption, and spread evenly, either at the edges or in the center of the tumor. DSA is believed to be an accurate procedure to provide a detailed description of the feeding artery; enhancement patterns of hepatoblastoma were influenced by an adequate TACE.
RESUMEN
Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has changed the focus of healthcare and become a public health challenge around the world. The coinfection of SARS-CoV-2 with other microorganisms, including fungi, can cause difficult diagnosis and a worse prognosis. Pneumocystis jirovecii pneumonia (PJP) is a common opportunistic infection in human immunodeficiency virus (HIV) patients. However, sometimes the diagnosis is late presented after PJP finding on chest X-ray. We report a 24-year-old man with COVID-19 and PJP. Reverse transcriptase-polymerase chain reaction showed positive for SARS-CoV-2. HIV diagnosis was late presented after PJP finding on chest X-ray examination. HIV serology was positive with an absolute CD4+ count was 16 cells/mm3. He was treated with remdesivir IV, methylprednisolone IV, heparin, and cefoperazone-sulbactam IV. He was discharged after being admitted for 25 days. HIV treatment was started in outpatient services. Radiological diagnostic to diagnose concurrent COVID-19 and PJP pneumonia are important, especially in the setting where microscopic examination of sputum or Bronchoalveolar Lavage Fluid (BALF) is not available, or because BAL and sputum induction are aerosol-generating procedures that potentially increase the risk of COVID-19 transmission. HIV testing in COVID-19 patients was also should be considered as part of directed screening in patients presenting with features of PJP, especially for those with unknown HIV status. The determination of an appropriate corticosteroid dose is important to treat both COVID-19 and PJP with severe clinical features. Proper diagnosis and treatment co-infections are urgently needed in this current pandemic to reduce morbidity and mortality.
RESUMEN
Colocutaneous fistula with nephrocutaneous fistula is a rare condition. Renal replacement lipomatosis is the result of the atrophy and destruction of renal parenchyma. We report a 60-year-old male with intermittent drainage mucus and fluid from ulcer of his right lumbar region. Renal ultrasound and plain abdominal X-ray revealed a chronic parenchymal disease with stone of the right kidney. Fistulography showed a fistula tract connecting the skin and the right pelvicalyceal system and the colon. Computerized tomography demonstrated a renal calculus with a massive fatty proliferation. The patient was planned for right nephrectomy and excision of the sinus tract.
