We report the case of a patient who presented for back pain with paresthesia, and the CT showed vertebral lysis of aneurysmal origin. The aneurysm of the thoracic aorta compresses the anterior surface of the dorsal vertebrae and by mechanical effect is responsible for the destruction of the opposite bone. The knowledge of this cause is very important considering the frequency of other tumoral and infectious causes of this affection.

We report an extremely rare case of Mirizzi syndrome in which it was possible to observe the process of development of cholecystobiliary fistula from asymptomatic cholecystolithiasis until unavoidable surgical intervention 4 years later. A 68-year-old woman presented at our hospital with right upper quadrant pain. She had been diagnosed as having asymptomatic cholecystolithiasis 4 years previously. Diagnostic abdominal computed tomography (CT) had revealed a 1.9 cm radiopaque stone, and thereafter, the patient had been monitored by imaging alone. CT conducted 6 months before the present admission revealed that the gallbladder stone was compressing the common hepatic duct, although the patient remained asymptomatic. On admission, abdominal CT showed that the gallbladder stone was obstructing the common bile duct with dilatation of the intrahepatic duct. Endoscopic retrograde cholangiopancreatography revealed a round filling defect at the confluence of the common bile duct and the image of the cystic duct; therefore, the patient was categorized as having Mirizzi syndrome type III, according to the Csendes classification. Intraoperative findings revealed a cholecystobiliary fistula involving up to two-thirds of the circumference of the common bile duct.

The contents of the hernia range from fat to intra-abdominal organs. They are primarily pathologies of neonates and most commonly occur unilaterally. These hernias have been described in isolation and as one part of a group of malformations. There have been reports of Bochdalek hernias in association with myelomeningocele and other neural tube defects. We present a unique case of bilateral Bochdalek hernias in a 35-year-old female with an Arnold-Chiari I malformation. learn more Copyright © 2020 Julian Fazi et al.There is a well-established association between inhalational exposures and acute eosinophilic pneumonia (AEP). The most reported exposure is cigarette smoking. Here, we present a case of progressive shortness of breath and nonproductive cough in a college student with no significant medical history, approximately 10 days after inhaling cannabis aerosols on two separate occasions. He was started on empiric antibiotics and bronchodilators without improvement. He was diagnosed with AEP based on peripheral eosinophilia and high-resolution CT image results. He made rapid recovery on intravenous glucocorticoids. Vaping has gained popularity among young adults mainly due to the perception that it is a safe alternative to smoking. This case shows that there may be a false sense of security with vaping. Vaping poses a yet-to-be quantified public health threat, which requires further studies.

It may present with signs of hypovolemic shock without apparent cause. While there are no specific guidelines for the management of patients diagnosed with such condition, wide debate in the literature relating to patient selection for surgery remains unresolved, and recently there seems to be a trend increasingly favorable towards early surgical intervention. Video-assisted thoracic surgery emerges as an excellent option for stable patients and has now been considered the gold standard treatment for spontaneous hemopneumothorax. We report the case of a 17-year-old male patient who presented to the emergency department with a history of sudden chest pain and dyspnea, with no previous evidence of trauma. On admission, the patient presented with hypotension, tachycardia, and cutaneous pallor. Chest X-ray showed hydropneumothorax on the left hemithorax; then, chest tube was placed with an initial drainage of 2000 ml of blood.

It is characterized by the development of lymphoid follicles with germinal centers in the walls of small airways. It falls under the category of lymphoproliferative pulmonary diseases (LPDs) and commonly occurs in relation to connective tissue disease, immunodeficiency, infections, interstitial lung disease (ILD), and inflammatory airway diseases. Computerized tomography (CT) findings include centrilobular nodules with patchy ground glass infiltrate, tree-in-bud findings, and air trapping. It can very rarely present as diffuse cystic lung disease. We present two cases of FB. The first case is associated with Human Immunodeficiency Virus (HIV) infection and asthma with diffuse cystic changes on the CT. The second case is associated with reactive airway disease and gastroesophageal reflux disease (GERD) with the classic centrilobular nodules and ground glass opacities on the CT.

First-line pharmacological treatments for both OCD and PTSD are primarily based on antidepressants, including Selective Serotonin Reuptake Inhibitors (SSRIs) and Serotonin-Noradrenaline Reuptake Inhibitors (SNRI) such as Venlafaxine for PTSD. Second-Generation Antipsychotic (SGA) augmentation has shown good outcomes for nonresponsive OCD cases. However, evidence on the use of SGA in PTSD is more limited. In the present paper, we report on comorbid OCD-PTSD successfully treated with aripiprazole augmentation of sertraline. Shared psychopathological and pharmacological aspects of the disorders are discussed. Copyright © 2020 Rodolfo Rossi et al.
