Utility of cone beam computed tomography for rare temporal bone lesion: A case report.

This case report aims to describe the clinical presentation, imaging findings, diagnostic challenges, and management of a patient with a cerebellopontine angle lesion. A 63-year-old woman presented with progressive headaches, tinnitus, right ear pressure, and dizziness. Initial imaging studies (computed tomography and magnetic resonance imaging) suggested either a thrombosed aneurysm or a lipoma.

Socioeconomic disparities and the genomic landscape of gastric cancer.

The genomic characteristics of Peruvian patients with gastric adenocarcinoma from diverse socioeconomic backgrounds were examined in consideration of the possibility that patients from different socioeconomic backgrounds may be exposed to different risk factors. We conducted a prospective pilot study in two Peruvian cities (Lima and Ica). This study enrolled 15 patients from low socioeconomic status (LSES) and 15 patients from medium/high socioeconomic status (MHSES).

Gastric adenocarcinoma with high‑level microsatellite instability: A case report.

Gastric cancer (GC) ranks fifth on the list of the most common malignancies worldwide. In Peru, gastric neoplasms are considered the second leading cause of mortality among males. Among the molecular subgroups of GC, microsatellite instability presents a favorable prognosis due to its hypermutated phenotype, which activates immunosurveillance.

Traumatic scalp arteriovenous fistula post capillary implantation successfully treated using PHIL embolic agent.

Background: A traumatic arteriovenous fistula of the scalp due to hair transplantation (AVFHT) is a rare fistulous communication between branches of the arteries and draining veins in the scalp's subcutaneous tissue. Its incidence is unknown and its clinical manifestations may range from a pulsatile mass to seldom epilepsy. Surgery and interventional approaches (percutaneous and endovascular embolization) using coils and embolic agents such as Onyx have been used as treatment options.

An occult iatrogenic pneumothorax as a cosmetic procedure complication.

A pneumothorax is the abnormal gas accumulation within the pleural space. We present a case of a patient with an occult iatrogenic pneumothorax who presented with symptomatic anemia that substantially improved after a transfusion, diverting the clinical suspicion. As a result, she developed acute respiratory distress, initially considered secondary to a possible pulmonary embolism vs.

Spontaneous rupture of chemotherapy catheter diagnosed using chest X-ray oblique projections: An interventional radiology approach.

Totally implanted central venous port systems are widely used to access central veins for patients needing long-term therapy. These devices have low rates of complications and are commonly used to administer medications like chemotherapeutic agents. Spontaneous rupture of a catheter segment is a rare mechanical complication, usually belatedly diagnosed and presenting with complications.

Characteristics of gastric cancer around the world.

Gastric cancer is one of the most important malignancies in the world due to the high burden of disease and lethality. In this work, we compared the main characteristics of gastric cancer between different regions of the world. We reviewed public repositories to retrieve epidemiological, molecular, clinicopathological, and risk factor data.

Seroprevalence Detection and Rabies Virus Absence in an Urban Raccoon () Population in a Highly Populated Area, Costa Rica.

Leptospirosis and rabies are zoonotic diseases of public health importance and endemic diseases in tropical countries such as Costa Rica. Peridomestic wild animals such as raccoons ( have been implicated as competent hosts of spirochetes and rabies virus. This study focused on understanding the role of urban raccoons in the dynamics of leptospirosis and rabies in a tropical environment.

Helicobacter pylori: History and facts in Peru.

Helicobacter pylori (H. pylori) is a cosmopolite bacteria and the main responsible for the high burden of gastric cancer in developing countries, such as Peru. In this review, we describe some historical facts in the H.

Hypericum silenoides Juss. and Hypericum philonotis Cham. & Schlecht. extracts: in-vivo hypolipidaemic and weight-reducing effects in obese rats.

Objectives: This study was carried out to assess the anti-obesity effect of Hypericum silenoides Juss. and Hypericum philonotis Cham. & Schlecht.

Chromobacterium violaceum Infection in a free-ranging howler monkey in Costa Rica.

Chromobacterium violaceum is a gram-negative saprobe bacterium that is a rare opportunistic pathogen in mammals. There are numerous reports in humans including fatalities, but no record exists in free-ranging nonhuman primates. Here we report an infection by C.

Postmortem findings and opportunistic infections in HIV-positive patients from a public hospital in Peru.

There is a paucity of HIV autopsy data from South America and none that document the postmortem findings in patients with HIV/AIDS in Peru. The purpose of this autopsy study was to determine the spectrum of opportunistic infections and the causes of mortality in HIV-positive patients at a public hospital in Lima. Clinico-epidemiological information regarding HIV infection in Peru is also reviewed.
