Opportunistic fungal infections are common in human immunodeficiency virus (HIV) infected patients and commonly occur at some point during their illness. Though estimates show that these infections ...can occur in HIV patients with the same frequency as in the control group, their presentations are more severe and variable in HIV/acquired immunodeficiency syndrome. We present an HIV infected case with multiple fungal infections. This patient had onychomycosis due to Aspergillus niger, tinea cruris caused by Trichophyton rubrum, oral thrush and balanoposthitis due to Candida albicans.
Pediatric cervicofacial actinomycosis is a rare occurrence consequent to dental infections and manipulations or maxillofacial trauma. The clinical presentation ranges from multiple draining sinuses ...to swellings resembling tumors and cysts. The present unusual case had congenital dermoid cyst of mid upper lip with Actinomyces israelii infection identified on microscopy, culture, and histopathology. A successful outcome in the present case was obtained using combination of medical and surgical treatment.
Candida lipolytica is weakly pathogenic yeast, which is rarely isolated from the blood. We recovered this species from repeated blood samples and in the central venous catheter in a debilitated ...pediatric patient of tubercular meningitis. Identity was established on the basis of colony morphology and sugar assimilation tests (ID 32C assimilation profile). The fungemia and associated fever subsided after the removal of catheter and amphotericin B therapy. The data suggest that though of low virulence and usually a contaminant, C. lipolytica is emerging yeast pathogen in cases of catheter-related candidemia. Pathogenicity is indicated by isolation from repeated samples as in our case. Intensive therapy is recommended in cases not resolving spontaneously or responding to removal of catheter alone.
Cutaneous sporotrichosis, a subcutaneous mycotic infection is caused by
the saprophytic, dimorphic fungus Sporothrix schenckii. It commonly
presents as lymphocutaneous or fixed cutaneous lesions ...involving the
upper extremities with facial lesions being seen more often in
children. The lesions are polymorphic. The therapeutic response to
saturated solution of potassium iodide is almost diagnostic. We
describe a culture-proven case of cutaneous sporotrichosis of the face
mimicking lupus vulgaris initially and basal cell carcinoma later, who
did not tolerate potassium iodide and failed to respond to treatment
with fluconazole. The patient had reactivation of infection following
an infiltration of the scar with triamcinolone acetonide injection.
Various other aspects of these unusual phenomena are also discussed.
Intralesional sodium stibogluconate (SSG) has become first line therapy for localized cutaneous leishmaniasis (LCL).
This study compares the efficacy of intralesional SSG given alone with that of ...intralesional SSG combined with intramuscular SSG.
Thirty-two patients aged between 5-56 years were included in the study. The first group received three injections of intralesional SSG on alternate days while the other group received three injections of intralesional SSG similar to the first group and the rest of the calculated dose as a simultaneous, intramuscular injection. Patients were followed up every four weeks to assess for cure/ the need for repeating the treatment.
Five patients from group 1 having small nodular lesions of < six months duration were cured after 1-2 treatment cycles. However, six patients with mucosal lesions, large lesions and lesions of > six months duration needed 3-5 treatment schedules. Most plaques and mucosal lesions in seven patients in group 2 cleared with two treatment cycles.
Intralesional combined with intramuscular SSG appears more effective in LCL and gave qualitatively superior healing than intralesional SSG given alone.
We assessed the occurrence of dengue fever in association with travel in a non-endemic hilly region. The clinical presentation and laboratory parameters of febrile patients with a travel history to ...an endemic region were studied, and the role of the laboratory in the diagnosis was affirmed.
Febrile patients presenting with clinical features defining dengue with a history of travel to an endemic area constituted the study group. Serum samples were tested for dengue-specific NS1 antigen and IgM, IgG antibodies. The demographic data were retrieved from the hospital information system. A hematological and biochemical workup was done and the results analyzed using percentage, proportion, mean, and median.
Out of 189 febrile patients, 58 were reactive to serological tests for dengue, with 47 (81%) males. The presenting features were chills and rigors, myalgia, cough, sweating, and vomiting. Thrombocytopenia (74.35%), lymphopenia (52.94%), and leucopenia (47.05%) were present in early disease, with AST >34 IU/L in 58.97% of the patients. The NS1 antigen was detectable between three and seven days of fever and the IgM antibodies after five days. The positivities to only NS1, both NS1 and IgM, and IgM alone were 60.34, 27.58, and 10.34%, respectively, and the median duration of fever was five, seven, and ten days, respectively. One case of dengue hemorrhagic fever and one of probable secondary dengue infection with detectable IgG were encountered.
Dengue fever remains unsuspected in febrile cases in non-endemic regions. History of travel is an essential criterion to suspect dengue. A non-specific clinical presentation eludes diagnosis. Serological tests for antigen and antibodies, and hematological and biochemical markers are vital for distinguishing the diagnosis.
Introduction: Pseudomonas aeruginosa has acquired a new metallo-β-lactamase (MBL) resistance gene responsible for increased resistance to fluoroquinolones, cephalosporins and carbapenems. Thus, it is ...essential to know the antibiotic sensitivity pattern and follow the antibiotic policy. Objectives: The objective of this study is to detect MBL production in clinical isolates by combined imipenem-ethylenediamine tetra acetic acid (IMP-EDTA) disc test. Materials and Methods: This study was conducted for a period of nine months from April 2011 to December 2011. A total of 66 consecutive isolates of P. aeruginosa were subjected to susceptibility testing by disc diffusion assay. IMP drug resistant strains were screened for MBL production by combined IMP-EDTA disc test. Results: Ciprofloxacin resistance was seen in 66.6% isolates followed by piperacillin in 51.5%. Resistance toward amikacin, ceftazidime, and cefoperazone were noted in 43.9%, 40.9%, and 37.8% isolates, respectively. In 37.8%, IMP resistance was observed. All IMP resistant strains (n = 25) were screened for MBL production. All the 25 isolates (100%) were MBL producers, exhibiting more than 7 mm zone size enhancement in IMP-EDTA combined disc test. Conclusion: Emergence of P. aeruginosa as MBL producer is becoming a therapeutic challenge. There is a need to implement routine antibiotic surveillance and judicious use of antibiotics.
Objectives: To study the epidemiology, clinical profile, and the role of rapid tests in the diagnosis of acute bacterial meningitis (ABM) in children (1-59 months).
Materials and Methods: A total of ...250 cerebrospinal fluid (CSF) and 187 blood samples received from clinically suspected cases of ABM were processed based on standard microbiological protocols. CSF samples were also subjected to antigen and nucleic acid detection. Antibiotic susceptibility testing was done according to the Clinical Laboratory Standards Institute guidelines. Children were also evaluated for outcomes and were followed up until 6 months after discharge.
Results: Eighty one cases were reported to be having clinically confirmed ABM, out of which group B Streptococcus was the most common pathogen detected in 49.3% (40) patients followed by Streptococcus pneumoniae, Staphylococcus aureus, Hemophilus influenzae type b, Escherichia coli, Klebsiella pneumoniae, and Neisseria meningitidis ACYW135 in 23.4% (19), 7.4% (6), 6.1% (5), 6.1% (5), 6.1% (5), and in 1.2% (1) patients, respectively. Complications were observed in 54.3% of the children. A follow-up of 6 months after discharge was possible in 39.5% (32) patients among whom sequelae were recorded in 93.7% (30) patients.
Conclusion: ABM remains a major cause of neurological sequelae worldwide. Although culture is the gold standard test for its detection, the investigation takes a longer time and the results are influenced by prior antimicrobial therapy. In such cases, rapid tests aid in the early diagnosis of ABM for instituting appropriate management.
The prevalence of hepatitis B is higher in tribal populations, compared to non-tribal populations in India. Therefore, this study aimed to investigate the risk factors, virological and biochemical ...profile of patients with hepatitis B in a tribal population.
This study analyzed data collected from a community-based project conducted in Spiti, Himachal Pradesh, from July 2015 to 2017. The study included adults and children inhabiting 40 cluster villages out of 82 villages in the subdivision. The blood samples were collected for liver panel, hepatitis B surface antigen (HBsAg), hepatitis B e antigen (HBeAg), Anti-HBe antibody (anti-HBe Ab) and Hepatitis B virus DNA (HBV-DNA).
HBsAg was positive in 23.08% of the population (968/4201), with a prevalence of 13.51% in children under 5 years of age. HBeAg positivity was seen in 22.4% of the participants, while anti-HBe Ab positivity was seen in 59.03% of the participants. HBeAg positive infection, HBeAg positive hepatitis, HBeAg negative hepatitis and HBeAg negative infection were seen in 18.06%, 1.98%, 6.17% and 74.01% of the participants, respectively. HBeAg positivity was highest in 2nd decade (40.83% vs 22% overall). Patients with HBeAg positivity exhibited higher levels of HBV DNA 1960 (IQR: 0-10
) IU/ml vs 97.2 (IQR: 0-2090) IU/ml,
< 0.001 and alanine transaminase (ALT) 22.5 (IQR: 16-33) U/L vs 19 (IQR: 14-26) U/L,
= 0.003 levels compared to HBeAg negative patients.
This study shows a high prevalence of hepatitis B in tribal population, particularly among children under 5 years of age.
