Coronavirus Disease 2019 and Cardiac Arrhythmias.

The emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a very contagious virus, has led to the coronavirus disease 2019 (COVID-19) pandemic. The clinical manifestations of this virus in humans vary widely, from asymptomatic to severe, with diverse symptomatology and even death. The substantial transmission from asymptomatic people has facilitated the widespread transmission of SARS-CoV-2, hampering public health initiatives to identify and isolate infected people during the pre-symptomatic contagious period.

Evaluation of the Ex-PRESS(®) P-50 implant under scleral flap in combined cataract and glaucoma surgery.

Aim: To evaluate the efficacy and safety of glaucoma drainage device Ex-PRESS(®) P-50 for combined cataract surgery and glaucoma.

Methods: Patients having cataract and open angle glaucoma or patients with open advanced glaucoma which needed two or more antiglaucoma medications were included. Combined cataract surgery and glaucoma with Ex-PRESS(®) P-50 model placed under scleral flap was performed.

Microangiopathy of common carotid vasa vasorum in type 1 diabetes mellitus.

Objective: We hypothesize that in type 1 diabetes vasa vasorum (VV) are affected by microangiopathic changes. For this purpose, we assessed the status of the VV signal in patients with type 1 diabetes.

Methods: The VV signal at the arterial adventitia of the common carotid artery was evaluated by contrast-enhanced ultrasound imaging.

Late postoperative capsular block syndrome: a case series studied before and after Nd:YAG laser posterior capsulotomy.

Purpose: To evaluate the clinical characteristics of the unusual late postoperative capsular block syndrome (CBS) and the effect of Nd:YAG laser posterior capsulotomy on visual acuity and refractive error as well as its possible complications.

Methods: In this retrospective cohort study, 12 eyes of 11 patients with late CBS who had undergone Nd:YAG laser posterior capsulotomy were reviewed. A complete ophthalmic examination including Scheimpflug camera and anterior segment optical coherence tomography (AS-OCT) imaging had been performed before and after posterior capsulotomy.

Comparison of anterior segment measurements with optical low-coherence reflectometry and rotating dual Scheimpflug analysis.

Purpose: To compare the anterior segment measurements obtained with optical low-coherence reflectometry (OLCR) (Lenstar LS 900, version 2.1.1) and rotating dual Scheimpflug analysis (Galilei G1, version 3).

Combined nevus of the tarsal conjunctival.

We present an unusual case of combined nevus of the tarsal conjunctiva and eyelid margin in a pregnant woman who noticed morphological changes of the lesion during pregnancy. The patient underwent a wide full-thickness eyelid excisional biopsy including tarsal conjunctiva. Histopathologically, a subepithelial combined nevus (nevocellular and blue nevus) was observed.

Clinical forms of presentation and evolution of diffuse sclerosing variant of papillary carcinoma and insular variant of follicular carcinoma of the thyroid.

We investigated whether the diffuse sclerosing variant of papillary carcinoma (diffuse sclerosing PC) and insular carcinoma (IC), two different subforms of differentiated carcinoma of the thyroid gland, have different clinical behaviors and prognosis in order to select appropriate therapy. The characteristics of clinical presentation, and outcome after therapy were evaluated in a series of 113 patients (18 males and 95 females) with differentiated thyroid carcinoma treated with the same protocol, of which 7 had diffuse sclerosing PC and 6 had IC; within this series, patients with diffuse sclerosing PC and IC were compared with 76 cases of papillary carcinoma (PC) and 24 cases of follicular carcinoma (FC), respectively. Diffuse sclerosing PC patients were younger (23+/-9 vs.

[Thyroid ophthalmopathy: clinical and tomographic study].

Background: To evaluate exophthalmos by Hertel exophthalmometer (HE) compared to computed tomography (CT), and extraocular muscle width on CT and its relation with the clinical course in patients with thyroidal ophthalmopathy.

Methods: On reviewed 118 orbits from 59 patients (50 women, mean age 40.6 y.

[Thyroid lymphoma: a clinico-pathological study].

Five cases of primary lymphoma of the thyroid followed at our hospital during the last decade are reviewed. The clinical and pathological characteristics are analysed and the therapeutical approach described. The age at the diagnosis ranged between 26 and 76 years, with a female versus male predominance (4 out of 5 cases).

Thyroid hemiagenesis in two sisters.

Two sisters with thyroid hemiagenesis are described. The patients presented diffuse thyroid enlargement of right lobe. The left lobe and isthmus were absent and thyroid scans were similar in both cases.
