“…Antibiotics used for the treatment of sore throat may sometimes be resistance. [5] A study done by Arora R et al reported fever as a most common feature in RF followed by polyarthralgia as the which were different from present study findings. [6] Chorea, subcutaneous nodules and erythema marginatum were reported by Joseph N, et al in 13.7%, 7.8% and 5.9% cases, respectively, but contrary to that none of the patients reported all three features in the present study.…”

Background: In developing countries like India, rheumatic fever (RF) is one of the important problems. RF can lead to rheumatic heart disease (RHD), which can be easily prevented by proper care. The present study was done to evaluate risk factors, clinical profile and an Echocardiogram (ECHO) data of RF/RHD patients. Methods: Total 70 patients were studied for complete blood count, electrocardiography, erythrocyte sedimentation rate, C-reactive protein, echocardiography, throat culture and anti-streptolysin O (ASLO) titre. Results: Mean age of the study population was 10.96±2.39 years. Study of clinical features showed that valvular involvement was present in 50 (71.42%) patients, which was most common, followed by congestive cardiac failure (CCF) [25 (35.7%)]. Raised erythrocyte sedimentation rate (ESR) and C -reactive protein was also recorded in the present study. Conclusion: The present study had identified different risk factors like valvular involvement, fever, sore throat infection and CCF as the component needed to be screened in patients with RF for early diagnosis and prompt treatment.

“…Viridans group Streptococcus spp. represent a major cause of endocarditis as well as bacteremia with septic shock in neutropenic patients (8), whereas serogroup C, F, and G beta-hemolytic streptococci can cause a wide array of infections, including upper respiratory tract infections, skin and soft tissue infections, necrotizing fasciitis, bacteremia, and endocarditis (9).

Daptomycin has demonstrated potent in vitro activity against many common staphylococci and streptococci, such as Staphylococcus aureus (including methicillin-resistant S. aureus [MRSA]; MIC 90 , 0.5 g/ml), coagulase-negative staphylococci (Staphylococcus epidermidis [MIC 90 , 0.5 g/ml] and less frequently isolated species), group A and B ␤-hemolytic streptococci (MIC 90 , Յ0.03 g/ml), Enterococcus faecalis (MIC 90 , 1 g/ml), and Enterococcus faecium (MIC 90 , 2 g/ml), in numerous investigations (4, 5). However, limited information exists on the activity of daptomycin tested against less frequently isolated Gram-positive species. We evaluated daptomycin activity tested against uncommonly isolated streptococci and three other Gram-positive groups derived from recent global surveillance programs.A total of 1,356 unique isolates (one per patient) were collected from documented infections and submitted to a monitoring reference laboratory (JMI Laboratories; North Liberty, IA, USA) where species identifications were confirmed using standard algorithms, Vitek systems (bioMérieux, Hazelwood, MO), matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) (Bruker Daltonics, Bremen, Germany), or 16S sequencing methods, when necessary. The organisms were obtained from the SENTRY Antimicrobial Surveillance Program platform from infections cultured in 112 medical centers located worldwide from 2008 to 2011 and stored in Trypticase soy broth with 15% glycerol in temperature-monitored Ϫ80°C freezers. The collection included viridans group streptococci (675 isolates; seven groups or species), ␤-hemolytic streptococci (BHS) other than Streptococcus pyogenes and Streptococcus agalactiae (598 isolates), Corynebacterium spp. (18 isolates; five species), Listeria monocytogenes (39 isolates), and Micrococcus spp. (26 isolates).The majority of isolates were from 77 U.S. medical centers, whereas four less common species isolates were obtained from worldwide hospital locations, including Streptococcus equisimilis, Streptococcus mutans, Corynebacterium spp., and L. monocytogenes.Daptomycin and comparators were tested for susceptibility by the reference Clinical and Laboratory Standards Institute (CLSI) broth microdilution method (6, 7). The cation-adjusted MuellerHinton broth was supplemented with 2.5 to 5% lysed horse blood when fastidious streptococcal species were tested. Also, the test medium was adjusted to contain physiological levels of calcium (50 mg/liter) when daptomycin was tested (6). All quality control results were within published ranges for daptomycin when S. aureus ATCC 29213 and E. faecalis ATCC 29212 were tested (7).Daptomycin exhibited potent in vitro activity when tested against seven groups of viridans group streptococci tested with MIC 50 and MIC 90 results ranging from Յ0.06 and Յ0.06 g/ml (Streptococcus bovis and Streptococcus dysgalactiae groups) to 0.5 and 1 g/ml (Streptococcus mitis, Streptococcus oralis, and Streptococcus parasanguinis), respectively ( Table 1).

“…These bacteria are usually associated with pharyngitis (exudative). In their course the infections are similar to those of Streptococcus pyogenes [6][7][8]. Such an aetiology of pharyngitis should be particularly taken into account if there is no improvement after standard therapy of group A streptococcal pharyngitis [8].…”

“…W opisywanym przypadku z próbki krwi wyhodowano paciorkowce grupy C. Bakterie te są zwykle kojarzone z zapaleniem gardła (wysiękowym), w swoim przebiegu przypominającym zakażenia wywołane przez Streptococcus pyogenes [6][7][8]. Taką etiologię zapalenia gardła należy szczególnie brać pod uwagę w przypadku braku poprawy po standardowym leczeniu zapalenia gardła wywołanego przez paciorkowce grupy A [8].…”

StreszczenieRaportowanie zdarzeń niepożądanych jest kluczowe dla stworzenia kultury bezpieczeństwa, która skupia się na ochronie lekarzy i pacjentów przed błędami medycznymi. W pracy przedstawiono śmiertelny przypadek zapalenia gardła wywołanego przez paciorkowce z grupy C u 56-letniego mężczyzny. Przebieg kliniczny, badania dodatkowe oraz wyniki sekcji zwłok wykazały, że ostateczną przyczyną zgonu była sepsa, w przebiegu której wystąpiła niewydolność wielonarządowa. Przypadek okazał się śmiertelny z powodu łańcucha zdarzeń niepożądanych, w tym błędów popełnionych przez lekarzy, pod których opieką pacjent znajdował się w trakcie 10 dni trwania choroby.Słowa kluczowe: zaniedbanie lekarskie, prawo karne, zgony w szpitalu, przepisanie leku. AbstractReporting on adverse events is essential to create a culture of safety, which focuses on protecting doctors and patients from medical errors. We present a fatal case of Streptococcus C pharyngitis in a 56-year-old man. The clinical course and the results of additional diagnostics and autopsy showed that sepsis followed by multiple organ failure was the ultimate cause of death. The clinical course appeared fatal due to a chain of adverse events, including errors made by the physicians caring for the patient for 10 days.
