The etiology, diagnostics, and treatment of the spasm of the near reflex - a narrative review.

Physiological adaptation of the eye to the visual perception of near objects consists of the "near triad": convergence, accommodation, and pupil miosis. Normally, these tend to revert when one stops fixating on a near object. Spasm of the near reflex (SNR) is a pathological phenomenon, which manifests itself by the persistence of the above-mentioned adjustments, which prevents the eye from returning to its relaxed state.

Unsatisfactory Long-term Results of Liver Transplant in Patients With Intrahepatic Cholangiocarcinoma.

Background: Cholangiocarcinoma is the primary liver tumor forming from the biliary epithelium. Two major subtypes of this disease are distinguished because of the initial location: the extra- and intrahepatic form. The latter disease is currently a controversial indication for liver transplant (LT).

Analysis of Patients With Incidental Perihilar Cholangiocarcinoma: An Old and a Persistent Burden for Liver Transplantation.

Background: Selected patients with unresectable perihilar cholangiocarcinoma (p-CCA) are now considered as candidates for liver transplant, provided they fulfill a strict perioperative treatment and staging protocol. The aim of this study was to examine the outcomes of patients after liver transplant with incidental p-CCA found in the liver explants.

Methods: A cohort of 10 patients with incidental p-CCA after liver transplant in the period between 1994 and 2019 was included in this retrospective analysis.
