Being the principal causative agent of bacterial pneumonia, otitis media, meningitis and septicemia, the bacterium Streptococcus pneumoniae is a major global health problem. To highlight the molecular basis of this problem, we have portrayed essential biological processes of the pneumococcal life cycle in eight watercolor paintings. The paintings are done to a consistent nanometer scale based on currently available data from structural biology and proteomics. In this review article, the paintings are used to provide a visual review of protein synthesis, carbohydrate metabolism, cell wall synthesis, cell division, teichoic acid synthesis, virulence, transformation and pilus synthesis based on the available scientific literature within the field of pneumococcal biology...

An elderly diabetic farmer presented with chronic nonhealing ulcer over the left foot, multiple liver abscesses, and right-sided pleural effusion. The patient developed septicemia and multiorgan failure. The pus grew pigment producing Chromobacterium violaceum. He was treated successfully with ciprofloxacin for a total duration of 15 days. This case is reported for its rare clinical presentation and resemblance with melioidosis. Of the 200 C. violaceum cases reported across the globe, this is the 14(th) case from India and the oldest in the literature...

BACKGROUND: Valid and comparable cause of death (COD) statistics are crucial for health policy analyses. Variations in COD assignment across geographical areas are well-documented while socio-institutional factors may affect the process of COD and underlying cause of death (UCD) determination. This study examines the comparability of UCD statistics in Hong Kong and Shanghai, having two political systems within one country, and assesses how socio-institutional factors influence UCD comparability...

BACKGROUND: The angiosome is a three-dimensional block of tissue supplied by a source vessel with its boundary outlined either by an anastomotic perimeter of reduced-caliber choke vessels or by true anastomoses with no reduction of vessel caliber. This article focuses on the role of these anastomotic vessels in defining flap survival or the necrotic pattern seen in fulminating meningococcal septicemia. METHODS: Experiments in pigs, dogs, guinea pigs, and rabbits over the past 46 years were reviewed, focusing on the necrosis line of flaps, the effects of various toxins in vivo, and correlating these results in the clinical setting...

Neisseria meningitidis is a rare cause of meningitis and septicemia in neonates. There are few published case reports of neonatal meningococcal meningitis complicated by subdural empyema, cerebral abscess and hydrocephalus. Few cases of neonatal meningococcal meningitis have been reported in the literature with none of them having the complication of multiple cerebral abscesses in early neonatal period (<seven days of life). We report a case of meningococcal meningitis with multiple cerebral abscesses which presented on fifth day of life and developed hydrocephalus at five weeks of life requiring a Ventriculo Peritoneal (VP) shunt...

To date, non-chemotherapy drug-induced severe neutropenia (neutrophil count of ≤0.5 x 10(9)/L) also called idiosyncratic drug-induced agranulocytosis is little discussed in the literature. In the present paper, we report and discuss the clinical data and management of this rare disorder. Areas covered: To do this, we carried out a review of the literature using PubMed database of the US National Library of Medicine. We also used data from the American Society of Hematology educational books, textbooks of Hematology and Internal medicine, and information gleaned from international meetings...

Septicemia is a growing problem within the United States (US), which increases mortality and the cost of care. Procalcitonin is a pro-inflammatory marker that could be useful in the diagnosis of infection. In the past, procalcitonin levels have been evaluated to diagnose sepsis or guide antibiotic therapy, but it was not determined if it would differentiate between sepsis and other causes of inflammation. Studies reviewed here showed procalcitonin to be a useful biomarker as an indication of bacterial infection...

REVIEW
Ramar Perumal Samy, Bradley G Stiles, Gautam Sethi, Lina H K Lim
This review briefly summarizes the geographical distribution and clinical impact of melioidosis, especially in the tropics. Burkholderia pseudomallei (a gram-negative bacterium) is the major causative agent for melioidosis, which is prevalent in Singapore, Malaysia, Thailand, Vietnam, and Northern Australia. Melioidosis patients are increasingly being recognized in other parts of the world. The bacteria are intrinsically resistant to many antimicrobial agents, but prolonged treatment, especially with combinations of antibiotics, may be effective...

Ecthyma gangrenosum (EG) is a well-described skin manifestation of Pseudomonas aeruginosa septicemia in immunocompromised patients. However, it can be seen in association with other bacteria, viruses, and fungi. We report a case of a 54-year-old African American female with metastatic gastric adenocarcinoma and recent chemotherapy and neutropenia who developed EG-like lesions due to methicillin-susceptible Staphylococcus aureus. We also review the literature to evaluate all reported cases of S aureus-associated EG and their clinical presentation, diagnosis, and treatment...

Typhoid fever is an important cause of morbidity and mortality in the developing world, particularly in children, but is infrequently observed in the developed world and can occur in patients without a significant travel history. Rhabdomyolysis as a complication has rarely been reported, and never in a child. A child with Salmonella enterica serovar Typhi septicemia, complicated by rhabdomyolysis, encephalopathy and pancreatitis is described and all 15 reported cases to date are summarized.

Septicemia remains a major cause of hospital mortality. Blood culture remains the best approach to identify the etiological microorganisms when a bloodstream infection is suspected but it takes long time because it relies on bacterial or fungal growth. The introduction in clinical microbiology laboratories of the matrix-assisted laser desorption ionization time-of-flight mass spectrometry technology, DNA hybridization, microarrays or rapid PCR-based test significantly reduce the time to results. Tests for direct detection in whole blood samples are highly desirable because of their potential to identify bloodstream pathogens without waiting for blood cultures to become positive...

Age, burn size, and inhalation injury are the major contributing variables related to burn mortality. While the female gender has been linked to higher mortality, the impact of socioeconomic status has not been well studied. The interplay between these three factors is also unknown. This study sought to clarify the effects of these variables on outcomes in a national sample of patients with burns. A retrospective review of 172,640 patient records of the National Burn Repository (version 8, 2002-2011) data was conducted...
