Guide to Infection Control in the Healthcare Setting
GUIDE TO INFECTION CONTROL IN THE HEALTHCARE SETTING Pneumococcus Author Roman Pallares, MD Imma Grau, MD Chapter Editor Ziad A. Memish, MD, FRCPC, FACP Topic Outline Key Issues Known Facts Controversial Issues Suggested Practice Suggested Practice in Under-Resourced Settings Summary References Chapter last updated: April 2018 KEY ISSUE • Streptococcus pneumoniae (Pneumococcus) remains a major pathogen worldwide, mainly in young children (<5 years), adults with immunosuppressive or chronic diseases as well as smokers and alcohol abusers, and older adults (≥65 years). Pneumococcal disease is more common in developing countries and occurs more often during winter. In recent years, important changes in the epidemiology of pneumococcal infections have been observed: 1. The emergence and spread of antibiotic-resistant pneumococci which make invasive pneumococcal infections (e.g., meningitis) difficult to treat. 2. The increased prevalence of pneumococcal disease in the elderly and in patients with chronic and serious underlying conditions (e.g., HIV, malignancies). 3. The increasing recognition of pneumococcal infections in patients admitted to healthcare institutions and nursing homes, childcare centers, and other closed institutions (e.g., jails, military camps). Several of these infections appeared as outbreaks due to antibiotic- resistant pneumococci. 4. In the years 2000s, there was a reduction in the incidence of pneumococcal infections after the introduction of pneumococcal conjugate vaccines (7-valent “PCV7”, 10-valent “PCV10”, and 13- valent “PCV13”) in children. • Most pneumococcal infections are considered community-acquired infections, and little attention has been paid to nosocomial and healthcare-associated pneumococcal infections. In addition, infection control measures for preventing pneumococcal infections in hospital and healthcare settings and nursing home facilities have not been widely considered in the literature. -

Common Questions About Streptococcal Pharyngitis MONICA G. KALRA, DO, Memorial Family Medicine Residency, Sugar Land, Texas KIM E. HIGGINS, DO, Envoy Hospice and Brookdale Hospice, Fort Worth, Texas EVAN D. PEREZ, MD, Memorial Family Medicine Residency, Sugar Land, Texas Group A beta-hemolytic streptococcal (GABHS) infection causes 15% to 30% of sore throats in children and 5% to 15% in adults, and is more common in the late winter and early spring. The strongest independent predictors of GABHS pharyngitis are patient age of five to 15 years, absence of cough, tender anterior cervical adenopa- thy, tonsillar exudates, and fever. To diagnose GABHS pharyngitis, a rapid antigen detection test should be ordered in patients with a modified Centor or FeverPAIN score of 2 or 3. First-line treatment for GABHS pharyngitis includes a 10-day course of penicillin or amoxicillin. Patients allergic to penicillin can be treated with first- generation cephalosporins, clindamycin, or macrolide antibiotics. Nonsteroidal anti-inflammatory drugs are more effective than acet- aminophen and placebo for treatment of fever and pain associated with GABHS pharyngitis; medicated throat lozenges used every two hours are also effective. Corticosteroids provide only a small reduc- tion in the duration of symptoms and should not be used routinely. (Am Fam Physician. 2016;94(1):24-31.

In these conditions, the administration of mucoactive agents is often indicated as adjuvant therapy. N-acetylcysteine (NAC) is a typical example of a mucolytic agent. A retrospective review of patients with pulmonary aspergillosis treated at the National Aspergillosis Centre in Manchester, United Kingdom, with NAC between November 2015 and November 2017 was carried out. Six Caucasians with Aspergillus lung disease received NAC to facilitate clearance of their viscid bronchial mucus secretions. One patient developed immediate bronchospasm on the first dose and could not be treated. Of the remainder, two (33%) derived benefit, with increased expectoration and reduced symptoms. Continued response was sustained over 6–7 months, without any apparent toxicity. In addition, a systematic review of the literature is provided to analyze the utility of NAC in the management of respiratory conditions which have unresponsive bronchial obstruction as a feature. -

Comparative Radiographic Features of Community Acquired Legionnaires' Disease, Pneumococcal Pneumonia, Mycoplasma Pneumonia, and Psittacosis
Thorax: first published as 10.1136/thx.39.1.28 on 1 January 1984. Downloaded from Thorax 1984;39:28-33 Comparative radiographic features of community acquired legionnaires' disease, pneumococcal pneumonia, mycoplasma pneumonia, and psittacosis JT MACFARLANE, AC MILLER, WH RODERICK SMITH, AH MORRIS, DH ROSE From the Departments of Thoracic Medicine and Radiology, City Hospital, Nottingham ABSTRACT The features of the chest radiographs of 49 adults with legionnaires' disease were compared with those of 91 adults with pneumococcal pneumonia (31 of whom had bacteraemia or antigenaemia), 46 with mycoplasma pneumonia, and 10 with psittacosis pneumonia. No distinctive pattern was seen for any group. Homogeneous shadowing was more frequent in legionnaires' disease (40/49 cases) (p < 0.005), bacteraemic pneumococcal pneumonia (25/31) (p < 0.01) and non-bacteraemic pneumococcal pneumonia (42/60) (p < 0.05) than in myco- plasma pneumonia (23/46). Multilobe disease at presentation was commoner in bacteraemic pneumococcal pneumonia (20/31) than in non-bacteraemic pneumococcal pneumonia (15/60) (p < 0.001) or legionnaires' disease (19/49) (p < 0.025). In bacteraemic pneumococcal pneumonia multilobe disease at presentation was associated with increased mortality. Pleural effusions and some degree of lung collapse were seen in all groups, although effusions were commoner in bacteraemic pneumococcal pneumonia. Cavitation was unusual. Lymphadenopathy occurred only in mycoplasma pneumonia (10/46). Radiographic deterioration was particularly a feature of legionnaires' disease (30/46) and bacteraemic pneumococcal pneumonia (14/27), and these groups also showed slow radiographic resolution in survivors. Radiographic resolution was fastest with mycoplasma pneumonia; psittacosis and non-bacteraemic pneumococcal pneumonia http://thorax.bmj.com/ cleared at an intermediate rate.
