Nocardiosis: A Neglected Disease.

Nocardiosis is a neglected tropical disease. It has varied geographical presence and a spectrum of clinical presentations. This review aims to focus on the epidemiology of nocardial infections with a systematic approach to their diagnosis and treatment. Nocardiacauses chronic infections and ailments, and may remain cryptic but progressive in its course. Unless suspected, diagnosis can be easily missed resulting in increased morbidity and mortality. Thorough knowledge of local epidemiology, demography, clinical course and presentation, diagnostic modalities, and antibiotic susceptibility patterns of the prevalent Nocardia species is essential to curb spread of this infection. This is a systematic review in which internet search has been done for citation indices (Embase, PubMed, Ovid, and other individual journals) till March 2020 utilizing the following key words "Nocardia," "taxonomy," "prevalence," "clinical features," "diagnosis," "treatment," and "susceptibility." We selected a total of 87 review articles, case series, and case reports all in English language.

New clonal strain of Candida auris, Delhi, India.

A new clonal strain of Candida auris is an emerging etiologic agent of fungemia in Delhi, India. In 12 patients in 2 hospitals, it was resistant to fluconazole and genotypically distinct from isolates from South Korea and Japan, as revealed by M13 and amplified fragment length polymorphism typing.

HIV and malnutrition: effects on immune system.

HIV or human immunodeficiency virus infection has assumed worldwide proportions and importance in just a span of 25 years. Continuous research is being done in many parts of the world regarding its treatment and vaccine development, and a lot of money has flown into this. However, fully understanding the mechanisms of immune depletion has still not been possible. The focus has also been on improving the quality of life of people living with HIV/AIDS through education, counselling, and nutritional support. Malnutrition further reduces the capacity of the body to fight this infection by compromising various immune parameters. Knowledge of essential components of nutrition and incorporating them in the management goes a long way in improving quality of life and better survival in HIV-infected patients.

Challenges and Road Map towards Starting a New COVID Hospital.

Background and Aim: With advent of the Coronavirus Disease 2019 (covid-19) pandemic, need for a dedicated government hospital was felt. Following directions after a cabinet decision, a dedicated Covid hospital was made functional within a month in Central district of Delhi. This manuscript briefs the journey and challenges experienced during this mission. Method: As per decision of the state health ministry, bed allocation was planned along with provision for diagnosis, treatment and prevention of Covid -19. Various trainings were simultaneously conducted, licences were obtained and manpower and material were arranged starting with procurement to service provision and waste management. Result: Concerted efforts resulted in initiation of clinical and diagnostic services within one month of initiation of teamwork. Government supported in all the licencing requirements and material management. The hospital became functional during the first wave; and by the start of second wave, 20-bedded fully equipped Intensive Care Unit (ICU) was ready with pressure swing adsorber (PSA) oxygen generator in premises. Conclusion: A well-coordinated action in the right direction with administrative support can help in achieving difficult targets. Opening a new hospital amidst lockdown and resource constraints in an emergency situation was a rewarding achievement.

Rhodotorula fungemia: two cases and a brief review.

Rhodotorula is emerging as an important cause of nosocomial and opportunistic infections. We present two cases of Rhodotorula mucilaginosa fungemia diagnosed over a period of 3 months at our hospital. The first case was of a pre-term neonate in the neonatal ICU who presented with respiratory failure and sepsis. The second involved an adult female who had been injured in a road traffic accident requiring an operation for a hematoma and was later shifted to the medical ICU. For a new hospital like ours, finding two cases of Rhodotorula fungemia within a span of 3 months prompted us to describe them in this report. These cases emphasize the emerging importance of Rhodotorula mucilaginosa as a pathogen and the importance of identification and MIC testing for all fungal isolates recovered from the blood stream.

Evaluation of hand hygiene compliance over the years, in an intensive care unit of a north Delhi hospital preparing for accreditation: A 3-year study.

INTRODUCTION: World Health Organization (WHO) initiated a global movement to achieve universal health coverage (UHC). Hand hygiene (HH) is critical for achieving UHC as it is a practical and evidence-based approach with a gaugeable impact on the quality of care and patient safety in healthcare. MATERIAL AND METHODS: A cross-sectional observational study was conducted in an intensive care unit of a government hospital spanning a period of 3 years. WHO single-observer direct observation technique was used and HH compliance was noted. The results were compared over the years since the hospital was preparing to undergo a National Accreditation Board for Hospitals and Healthcare (NABH) assessment. RESULTS: The overall compliance significantly increased over the years (P < 0.0001). HH compliance for hand rub (HR) and hand wash (HW) was compared among doctors, nurses, and ICU technicians, respectively. HR compliance remained more or less the same over the years (P = 0.4738) while HW compliance significantly improved (P < 0.0001). CONCLUSIONS: This is one of the first studies from our country evaluating HH compliance over the years in a healthcare setup undergoing accreditation. During the course of the study, we observed a significant increase in HH compliance. This can be attributed to the unflinching support of our hospital's administration and relentless efforts of our infection control team. This is our first step initiative towards improving HH and thus preventing healthcare-associated infections (HCAIs) in our setup.

Rhinocerebral zygomycosis with pulmonary aspergillosis in a non-HIV-infected patient: an unusual case report from India.

Zygomycosis and aspergillosis are two serious opportunistic fungal infections that are commonly seen in immunocompromised patients. Since both these fungi invade vessels of the arterial system, an early and rapid diagnosis by direct examination of KOH mounts of the relevant clinical sample can confirm the diagnosis. Here, we present an unusual case of a diabetic patient who presented with nasal blockade and bleeding for 2 months, along with occasional haemoptysis for 15 days. On investigation, the patient was diagnosed with a case of rhinocerebral zygomycosis and was treated with amphotericin B (1 mg kg(-1) day(-1)), which was subsequently replaced with liposomal amphotericin B (2 mg kg(-1) day(-1)). However, the patient did not completely respond to therapy as haemoptysis continued. Further investigations revealed the presence of Aspergillus flavus in respiratory specimens. Thus, a final diagnosis of rhinocerebral zygomycosis with pulmonary aspergillosis in a non-HIV-infected patient was made, but due to infection of two vital sites by these fungi, the patient could not be saved.

Salmonella enterica serotype Typhi from a case of breast abscess.

Enteric fever is an acute systemic febrile infection caused by Salmonella enterica serotype Typhi. Breast abscess due to S. typhi infection is a rare sequelae. We report here a classical case of Salmonella typhi infection in a rare clinical form of a breast abscess in a non-lactating immuno-compromised female.

Isolation of Salmonella typhi from high vaginal swab in a case of septic abortion.

Salmonella Typhi can be a significant cause of morbidity and mortality in pregnant females with adverse outcomes. Risk of infections increases manifold during pregnancy due to hormonal changes and immunological phenomena. S. Typhi has the ability to cross placenta (vertical transmission) resulting in miscarriage, stillbirth or premature labour. We report a case of a pregnant female who was admitted to emergency department with fever, missed abortion and hypovolaemic shock. Subsequently, S. Typhi was isolated from her high vaginal swab and blood cultures. Follow-up cultures were negative for S. Typhi, and the patient was discharged after 10 days. The possibility of salmonellosis should be considered if a pregnant woman residing in an endemic area presents with high-grade fever. Furthermore, it should be promptly treated to prevent foetal loss.

Staphylococcal bullous impetigo in a neonate.

An otherwise healthy, full-term neonate presented at day 15 of life to the pediatric emergency with generalized papulo-pustular rash for 2 d. This was finally diagnosed as bullous impetigo caused by Staphylococcus aureus (S. aureus). The skin lesions decreased significantly after starting antibiotic therapy and drainage of blister fluid. There was no recurrence of the lesions on follow-up. This case of generalized pustular eruption due to S. aureus in a neonate is reported, as it poses a diagnostic dilemma and can have serious consequences if left untreated.

Staphylococcus aureus bacteremia: targeting the source.

Bacteremia due to Staphylococcus aureus is one of the major causes of morbidity and mortality in India, but studies targeting the source of Staphylococcus aureus bacteremia are lacking. S. aureus has a vivid armamentarium consisting of toxins, adhesins, and other virulence factors by virtue of which it can cause varied types of infections, sometimes of a serious nature. This review highlights the possible causes of S. aureus bacteremia, and discusses the necessity of tracing its source and eliminating it with proper antibiotic therapy to avoid recurrences or relapses.

Comparison of an automated system with conventional identification and antimicrobial susceptibility testing.

The present study was designed to compare a fully automated identification/antibiotic susceptibility testing (AST) system BD Phoenix (BD) for its efficacy in rapid and accurate identification and AST with conventional manual methods and to determine if the errors reported in AST, such as the (very major errors) VME (false susceptibility), (major errors) ME (false resistance), and (minor errors) MiE (intermediate category interpretation) were within the range certified by FDA. Identification and antimicrobial susceptibility test results of eighty-five clinical isolates including both gram-positive and negative were compared on Phoenix considering the results obtained from conventional manual methods of identification and disc diffusion testing of antibiotics as standards for comparison. Phoenix performed favorably well. There was 100% concordance in identification for gram-negative isolates and 94.83% for gram-positive isolates. In seven cases, Phoenix proved better than conventional identification. For antibiotic results, categorical agreement was 98.02% for gram-positive and 95.7% for gram-negative isolates. VME was 0.33%, ME 0.66%, MiE 0.99% for gram-positive isolates and 1.23% VME, 1.23% ME, and 1.85% MiE for gram-negative isolates. Therefore, this automated system can be used as a tool to facilitate early identification and susceptibility pattern of aerobic bacteria in routine microbiology laboratories.

Cytomegalovirus infection in non-immunosuppressed critically ill patients.

Cytomegalovirus (CMV) is an important and common cause of mortality and morbidity in immunocompromised patients such as those with HIV/AIDS, transplant recipients on immunosuppressive therapy, and malignant hematological disease. After primary infection with CMV the virus becomes latent in multiple organs and can later be reactivated during severe dysregulation of the immune system. A large population carry dormant virus and are thus at risk for reactivation. However, reactivation of CMV has been reported in "non-immunosuppressed patients" such as severe trauma, sepsis, shock, burns, cirrhosis and other critically ill patients lying in the intensive care units. Therefore, the intensivists are increasingly facing a dilemma of identifying such patients to treat and there is a debate if there is a scientific justification for prophylaxis in such immunocompetent patients.

A finding of live Fasciolopsis buski in an ileostomy opening.

A pair of live Fasciolopsis buski wriggled their way out through the ileostomy opening in a young adult male who had recently migrated to Delhi and had met with a road traffic accident. Finding this parasite in the national capital, a non endemic area for Fasciolopsiasis, prompted us to emphasize the importance of changes in the ecology, human demography, and human behaviour that may provide an environment conducive to their adaptability to the new geographical requirements. Awareness of Fasciolopsiasis, which is endemic in some regions of India, especially in rural settings, is an important issue because early diagnosis is essential. Hence, a surveillance mechanism among the migratory population to institute preventive interventions is necessary.

Primary amoebic meningoencephalitis: first reported case from Rohtak, North India.

A fatal case of primary amoebic encephalitis (PAM) in a 20 year old boy, a proven case of acute leukemic leukemia (ALL) type L2, in remission is described. No history of swimming could be elicited. The clinical presentation, the isolation of the amoeba from the cerebrospinal fluid (CSF), the poor response to amphotericin B, and the ultimately fatal outcome are all consistent with the diagnosis of PAM. On the basis of its ability to grow at temperature 42 degrees C and 45 degrees C, morphology of trophozoite, and the presence of flagellate forms in CSF, the amoeba was identified as Naegleria fowleri. Other drugs used in combination with amphotericin B are tetracycline, rifampicin, and miconazole. A possibility of PAM should always be considered in all cases of acute purulent meningoencephalitis in which no bacteria or fungus are found.
