[Telemedicine as a follow-up ambulatory strategy for COVID patients at the Hospital Italiano de San Justo].

Introduction: Due to the COVID-19 pandemic, health systems have had to adapt to the growing demand for care. Telemedicine is a practical tool for outpatient monitoring of correctly selected patients.

Materials And Methods: A descriptive study of a prospective cohort of patients under telemedicine follow-up at the Hospital Italiano de San Justo was carried out.

[Ascariasis in the intrahepatic biliary duct: about a case in pediatrics].

Twenty five percent of the world population is affected by Ascaris lumbricoides. Hepatobiliary ascariasis occurs in areas with high endemicity and great amount of parasitic load, generating intense inflammation to fibrosis. We report a twoyear- old patient that consults about abdominal distension and cough of one month of evolution associated with 72 hours of fever.

[Not Available].

Polyamphoteric washing solutions (PWS) have been used for several years, mainly in industries, for cases of chemical ocular or cutaneous splashes by acid or alkali. We collected 37 cases reporting the use of PWS for ocular and cutaneous chemical splashes from several centres. Among the 37 cases, 55.

[Cerebral hydatid disease: report of six pediatric cases].

Hydatid disease is a parasitic infection whose etiologic agent is Echinococcus granulosus. Human is an accidental intermediate host and the most common site is the liver. The brain involvement is unusual and up to 75% of cases are described in the pediatric population.

Echinococcosis in children: Experience in a tertiary care hospital outside the endemic area.

Echinococcosis is a zoonotic disease that is widely spread across Argentina and worldwide. It is acquired during childhood but it is more common during adulthood. The pediatric population accounts for 10-20% of all cases.

Preferred Management of Primary Deep Arm Vein Thrombosis.

Objective: Given its rarity, the management of primary upper extremity deep vein thrombosis is controversial. Although anticoagulation alone is commonly advocated for its treatment, it is unclear if this will reduce the risk of developing post-thrombotic syndrome (PTS). The aim of this "Evidence Driven" Clinical Scenario is to evaluate whether more aggressive treatments (including catheter directed thrombolysis or surgery) might help reduce the risk of PTS or recurrent venous thromboembolism in patients with primary upper extremity deep vein thrombosis (DVT).

Effect of angiotensin 2 receptor blockers on chronic obstructive lung disease mortality: A retrospective cohort study.

Introduction: Chronic Obstructive Pulmonary Disease (COPD) is the fifth cause of mortality worldwide. Systemic inflammation is a crucial element in its physiopathology. As Renin-Angiotensin System is one of the main components of this inflammatory neurohumoral cascade, Angiotensin Receptor Blockers (ARBs) might have an effect on mortality in COPD patients.

HIV testing patterns for United States Air Force personnel, 2008-2012.

Objective: This study evaluated 3rd generation human immunodeficiency virus (HIV) test patterns and HIV infection rates in the United States Air Force (USAF).

Study Design: Retrospective database study.

Methods: HIV enzyme-linked immunoassay (ELISA) and Western blot tests were analysed for all USAF personnel from 2008 to 2012.

Distribution and Numbers of Pygmies in Central African Forests.

Pygmy populations occupy a vast territory extending west-to-east along the central African belt from the Congo Basin to Lake Victoria. However, their numbers and actual distribution is not known precisely. Here, we undertake this task by using locational data and population sizes for an unprecedented number of known Pygmy camps and settlements (n = 654) in five of the nine countries where currently distributed.

[Ocular involvement in congenital Chagas disease].

Ophthalmic compromise is infrequent in children with congenital Chagas disease. We present 3 patients under 2 months of age, with ocular involvement, all of them referred to the hospital for ophthalmic evaluation of the premature newborn. The ophthalmic finding was bilateral severe vitreitis (posterior uveitis) related to Chagas disease.

[Experience with the regionalization of transfusion advice].

We represent an organization of transfusionnel advice at a regional level and we develop arguments and stages having allowed us to lead to this choice. This target was reached in two stages, which took place over 3 years. The regional transfusionnel advice leans on three fundamental points: a planned permanent organization, skilled and formed actors as well as adapted tools.

First visceral leishmaniasis focus in Argentina.

An eight-year old boy from Posadas (27 masculine 23'S, 55 masculine 54'W) was diagnosed with visceral leishmaniasis (VL) during 2006. Lutzomyia longipalpis was discovered in the backyard of his house, while the spread of canine visceral leishmaniasis was confirmed in Posadas. This is the southernmost report of a VL transmission focus and the first in Argentina.

[Late-onset schizophrenia or chronic delusion].

Historical Aspects: Chronic delusion occurring late in life has essentially been studied by European psychiatrists. "Late-onset schizophrenia" was first described and defined by Manfred Bleuler in 1943, as a form of schizophrenia which occurs after the age of 40. Later, British psychiatrists often used the term "Late-onset paraphrenia" interchangeably with "Late-onset schizophrenia" to designate this disorder.

Use of a monoclonal antibody and a DNA probe for diagnosing acute toxoplasmosis in ambiguous cases.

An unusual case of cerebral toxoplasmosis in an HIV negative 11 year old child is reported. Central nervous system disease was assessed immunohistochemically in a brain biopsy specimen with TgP8--a specific monoclonal antibody against Toxoplasma gondii antigens--thus confirming IgG and IgM serology, technetium scan findings, and clinical data. In addition, an active parasitaemia was confirmed by DNA in situ hybridisation assay in white cells using an ABGTg4 probe.

[Schnitzler's syndrome. A new case].

A new case of Schnitzler's syndrome is reported in a 72-year old man hospitalized for severe deterioration of his general condition associated with recurrent ancient urticaria. Paraclinical examinations, which showed inflammatory syndrome, bone condensation and IgM monoclonal gammapathy, led to the diagnosis of Schnitzler's syndrome, first described in 1972. Twenty-two cases have now been published, characterized by vasculitic urticaria, osteosclerosis and IgM macroglobulinaemia.

Hereditary angioedema: therapeutic effect of danazol on C4 and C1 esterase inhibitors.

Hereditary angioedema (HAE) is an inherited deficiency of C1 esterase inhibitor (C1 inh). The two types of genetic C1 inh deficiency are type I, which is quantitative, and type II, which is functional. For the purpose of the present study, four HAE patients were selected.

[Hereditary angioedema. Effect of danazol on C4 and functional C1INH].

Hereditary angioedema (HAE) is an inherited deficiency of the inhibitor of C1 esterase (C1 inh). Two types of genetic C1 inh deficiency have been described, type I: quantitative, and type II: functional. For the purpose of the present study, 4 out of 51 HAE patients were selected.

Ultrasonography in the management of unexplained renal failure.

A series of seven cases of acute renal failure is presented in which sonographic study of the kidneys provided diagnostic information not otherwise obtainable. Ultrasonic imaging should be among the first diagnostic procedures applied in cases of acute unexplained renal failure because it provides rapid answers to the most urgent management problems--whether there is an obstructive component, and what is the potential for recovery.
