Article Synopsis
  • - Sickle cell disease varies in its genetic presentation and primarily impacts populations with ancestry from sub-Saharan Africa, parts of the Western Hemisphere, Saudi Arabia, and India, due to the protective effects against malaria for carriers of certain genes.
  • - While newborn screening for sickle cell disease is improving early diagnosis, many patients lack access to proper treatment, follow-up care, and genetic counseling, leading to increased health risks.
  • - The case of a 36-year-old man highlights the severity of sickle cell complications, as he suffered a fatal sickling crisis, underscoring the potential for severe outcomes even in patients with the milder HbSC form of the disease.

In 2005, the combined pulmonary fibrosis and emphysema (CPFE) was first defined as a distinct entity, which comprised centrilobular or paraseptal emphysema in the upper pulmonary lobes, and fibrosis in the lower lobes accompanied by reduced diffused capacity of the lungs for carbon monoxide (DLCO). Recently, the fibrosis associated with the connective tissue disease was also included in the diagnosis of CPFE, although the exposure to tobacco, coal, welding, agrochemical compounds, and tire manufacturing are the most frequent causative agents. This entity characteristically presents reduced DLCO with preserved lung volumes and severe pulmonary hypertension, which is not observed in emphysema and fibrosis alone.

Article Synopsis
  • Spontaneous hemoperitoneum is a serious condition often related to issues with major arteries, primarily due to diseases like atherosclerosis, but can also arise from nonatherosclerotic causes, as described by Slavin and Gonzales in 1976.
  • A case is presented involving a middle-aged man who suffered from hemoperitoneum caused by a ruptured middle colic artery aneurysm, leading to his death despite surgical intervention.
  • Autopsy findings revealed significant internal bleeding and damage, highlighting the importance of accurate diagnoses in rare vascular diseases through thorough examinations like autopsies.*

Article Synopsis
  • Lymphangioma is a rare, benign tumor caused by a lymphatic system malformation, often found in the head, neck, and axilla but can occur anywhere in the body.
  • In children, abdominal cystic lymphangiomas typically occur in the mesentery, causing symptoms like abdominal pain and intestinal obstruction.
  • A case study is presented of a child with fever and abdominal pain, which led to surgery revealing a cystic lymphangioma that may be considered in diagnosing acute abdominal issues in pediatric patients.

Context And Objective: Noninvasive strategies for evaluating non-alcoholic fatty liver disease (NAFLD) have been investigated over the last few decades. Our aim was to evaluate the diagnostic accuracy of a new hepatic ultrasound score for NAFLD in the ELSA-Brasil study.

Design And Settings: Diagnostic accuracy study conducted in the ELSA center, in the hospital of a public university.

Although the infection is well known and frequently found in hospitals and nursing care facilities, many cases are also reported outside these boundaries. In general, this pathogen infects debilitated patients either by comorbidities or by any form of immunodeficiency. In cases of respiratory infection, tobacco abuse seems to play an important role as a risk factor.

Primary lung lymphoma is a rare entity accounting for approximately 0.3% of all primary neoplasia of the lung and includes diffuse large B-cell lymphoma (DLBL) and lymphomatoid granulomatosis (LYG). Considering that clinical features may be similar, whereas epidemiology, morphology, and radiological features are different, the authors report a case of a middle-aged man who presented multiple pulmonary nodules in the lower lobes and ground-glass opacities scattered bilaterally on computed tomography.

Although infective endocarditis (IE) has been described in reports dating from the Renaissance, the diagnosis still challenges and the outcome often surprises. In the course of time, diagnostic criteria have been updated and validated to reduce misdiagnosis. Some risk factors and epidemiology have shown dynamic changes since degenerative valvular disease became more predominant in developed countries, and the mean age of the affected population increased.

First described by Berti in 1866 gastric volvulus (GV) is an uncommon and potentially lethal entity. GV occurs when the stomach twists by more than 180º resulting in obstruction of the alimentary tract, visceral ischemia, necrosis, and perforation. It is classified according to the rotation axis in organoaxial, mesenteroaxial or a combination of both.

Since the 1950s, aortic graft infections (AGIs) constitute one of the most feared complications after reconstructive vascular surgery. This complication is not frequent, ranging from 1% to 2% in the recently reported series; however, the high rate of death and morbidity after therapeutic attempts justifies its dreadful fame. The majority of cases occur during the first month after surgery.

Lung adenocarcinomas with a mixture of tubular or papillary pattern, sheet-like or trabecular architecture, eosinophilic cytoplasm with centrally located nuclei and alpha-fetoprotein-producing cells have been described as hepatoid adenocarcinomas. Hepatoid adenocarcinomas are mainly found in the stomach but rare cases in other organs have been described. Immunostaining for alpha-fetoprotein (AFP), hepatocyte paraffin 1 (HepPar-1) and thyroid transcription factor-1 (TTF-1) helps in the diagnostic workup.

First described in 1936, the diverticulum of Kommerell (DOK) is a dilatation of the proximal segment of an aberrant subclavian artery. Appearing more frequently in the left-sided aortic arch, the aberrant right subclavian artery passes behind the esophagus toward the right arm, causing symptoms in the minority of cases. Diagnosis is generally incidental with this pattern.

Sclerosing encapsulating peritonitis (SEP), also called encapsulating peritonitis, is a rare and benign cause of intestinal obstruction of unknown etiology. Its onset may be acute or subacute although there are some reports with a two-month history. More commonly, this entity is secondary to chronic peritoneal dialysis, ventriculoperitoneal and peritoneovenous shunting, the use of βblockers and systemic lupus erythematous.

Since when the first transesophageal echocardiography (TEE) was undertaken in 1975, technological advances have made this diagnostic modality more reliable. TEE indications became widespread in cardiac and non-cardiac surgeries, intensive care units, and ambulatory clinics. The procedure is generally considered a safe diagnostic tool, but occasionally complications do occur.

Omental infarction is a rare cause of acute abdominal pain, and the cause of omental infarction itself remains unknown. The diagnosis of omental infarction is occasionally made intra-operatively, because it is poorly known and presents no specific clinical features. Therefore omental infarction should always be considered in the differential diagnosis of abdominal inflammatory processes, mainly those affecting the right lower quadrant.

The focal calcification or ossification of the ligamentum flavum is a rare cause of thoracic myelopathy and most often occurs among individuals of Japanese descent. It is rare in other ethnic groups and in individuals below the age of 50. It is most often described at the lower thoracic level, being uncommon in the lumbar region and rare in the cervical region.

Article Synopsis
  • - Schistosomiasis is a widespread parasitic disease that remains a public health concern, particularly difficult to diagnose in its acute form, leading to misdiagnoses, underreporting, and overlooking by healthcare professionals in endemic regions.
  • - A case study highlights a young female patient in late puerperium suffering from significant symptoms like weight loss and abdominal pain, ultimately culminating in severe health deterioration and death.
  • - The autopsy revealed findings consistent with acute schistosomiasis, indicating that even in individuals previously exposed, the disease can progress rapidly and has the potential for severe outcomes, such as hepatic and respiratory failure.

Acute upper gastrointestinal bleeding is a potentially life-threatening emergency, especially in the elderly. This condition accounts for approximately 1% of all emergency room admissions. Among the causes of such bleeding is aortoesophageal fistula, a dreaded but apparently rare condition, first recognized in 1818.
