COVID-19 Management in Clinical Dental Care Part II: Personal Protective Equipment for the Dental Care Professional

Background: Facing the coronavirus disease 2019 (COVID-19) challenge on a global level, dental care professionals are encouraged to optimize universal precautions and adopt measures that ensure protection against infection by contaminated aerosols and droplets. Although aerosol transmission is possible, direct contact through large droplets is probably responsible for the vast majority of transmissions. Methods: This paper is the second of a series of 3 on the management of COVID-19 in clinical dental care settings and aims to describe the selection and use of personal protection equipment (PPE) by dental care professionals (DCP), with consideration of the level of risk associated with the planned procedures. PPE selection depends directly on the local epidemiological setting, the patient's characteristics, and the level of risk of the planned procedures. The procedures performed in the office environment are classified as low-, moderate-, or high-risk. Moderate risk includes 2 further sublevels associated with the cleaning, disinfection, and sterilization of materials for clinical procedures that do not generate aerosols. The training of DCP on how to properly don (put on) and doff (remove) PPE is as important as choosing the appropriate PPE because it can be associated with a risk of infection. Discussion: When there is limited availability of PPE, measures should be adjusted to the risk associated with the intervention. Assuming that an effective COVID-19 vaccine will be developed, once it becomes widely available for DCP, PPE requirements will likely be different. Conclusion: The proper use of PPE, together with the adoption of other operational procedures, can provide effective protection against microorganisms being transmitted via body fluids or in the air.     

Response to direct‐acting antivirals for hepatitis C treatment in vertically HIV/HCV co‐infected patients

Direct‐acting antivirals (DAAs) for HCV treatment have improved tolerance and efficacy among adults, but experience in vertical transmission is scarce. In our vertically HIV/HCV co‐infected youth cohort of 58 patients, DAA achieved excellent rates of cure among naïve and pretreated individuals. Treating vertically infected seems important as 29.6% displayed advanced fibrosis at treatment initiation.     

Age related macular degeneration surgery

Age related macular degeneration (ARMD) is a disease in which the retinal pigment epithelium (RPE) is damaged in the central retinal area. In the exudative form, the vision loss is due to choroidal neovascularization, while in the nonexudative or atrophic form, there is a vision loss because of the retinal pigment epithelium atrophy. Treatment which proved to be efficient in lowering the risk of severe vision loss in the exudative form includes laser photocoagulation, photodynamic therapy, transpupilary thermotherapy and as surgical treatment, the controversial subretinal membrane extraction. In all these situations the RPE is damaged by the disease itself and by the therapeutic procedure too. Retinal translocation is a surgical procedure that intends to remove the neurosensory retina from an area with damaged RPE to an healthy RPE area, through a 360 degrees retinotomy or through a limited one. This paper present some ARMD cases treated by subretinal membrane extraction and one by limited retinal translocation. The question which is still remaining is which are the risks and benefits for the following treatment procedures: laser photocoagulation, photodynamic therapy, transpupilary thermotherapy and surgical approach?     

Internal tamponade in proliferative diabetic retinopathy surgery

Vitreous hemorrhage has been the most common indication of posterior vitrectomy in diabetic retinopathy. Now, the leader is tractional retinal detachement and many others: rhegmatogenous retinal detachement, fibrovascular proliferations membranes, huge premacular hemorrhage. During vitrectomy procedure it may be necessary internal tamponade using air, expanding gases, silicon oil and/or perfluorocarbon liquids.     

Headache in children and adolescent in ambulatory practice

Headache in children and adolescent represents one of the most frequent and potentially severe pathological conditions, requiring a paediatric consult. The purpose of the study was to establish the headache prevalence from the total paediatric consultations in ambulatory practice as well as to establish the main etiological causes of the headache. The study, including 400 children and adolescents (M/F ratio=150/250, U/R ratio=290/110) with headache selected from 3100 cases between 2003 and 2004, in two practices (one general paediatric office and one paediatric neuropsychiatry office) from the Outpatient Clinic of the "Sf. Spiridon" Hospital of Iasi, has shown a prevalence of headache of 12.9%, the most affected age group being that of 5-12 years (52.5%). The etiologic study proved a high frequency of trauma 46.25%, ophthalmologic diseases 13.28%, psychogenic headache 10.75%, migraine 10%, general causes (infections, anaemia, hypoglycaemia) 9%, ENT causes 6.25%, intracranial causes 0.75%. The study confirms the necessity of a multidisciplinary approach, most causes being benign and the prognosis favourable in most cases.     

Aspects of optical coherence tomography in diabetic retinopathy

Optical coherence tomography is a new and very useful technique for diabetic patients. It is used to determine the early changes in diabetic retinopathy and to help the ophthalmologist to choose the appropriate therapy.     

An overview of the National Consultative Council of Immunization in Honduras

The State of Honduras instituted its technical advisory committee on immunization in response to recommendations made by the Pan-American Health Organization (PAHO) and the National Extended Program of Immunization (EPI). On 9 October 1999, the “National Consultative Council of Immunization” (NCCI) was established to provide support and recommendations to the EPI program for the eradication, elimination and control of vaccine-preventable diseases. The seven permanent members of the Council are all paediatricians. Additionally, there are liaison members (from PAHO, the national EPI team, and others) who participate in NCCI meetings when required. Meetings take place three times per year. The high quality of Council recommendations is demonstrated by the fact that the health authorities have adopted all of them.     

Antidiarrhoeal Activity of the Alcoholic Extract of the Leaves of Butea frondosa Koen. Ex Roxb

The study evaluated the antidiarrhoeal property of the alcohol extract of Butea frondosa leaf on mice and rats. Studies revealed that at a dose of 25 and 75 mg/kg a considerable reduction in the extent of diarrhoea was observed but at a dose of 100 mg/kg the animals appeared completely constipated when subjected to castor oil induced diarrhoea and intestinal motility model. Therefore, Butea frondosa can be regarded as an effective antidiarrhoeal.
