Diagnosis of EPTB is often challenging as it resembles other granulomatous conditions pathologically. TB culture remains the gold standard for definitive diagnosis, but it takes longer time and WHO has recommended the use of GeneXpert Ultra for rapid diagnosis. This study aims the utility of GeneXpert Ultra for diagnosis of tubercular adenitis.MethodsThis prospective study included the suspected tubercular adenitis patients with lymphnode size of ≥ 20mm. Patients diagnosed with other aetiology of adenitis were excluded. Excision biopsy was performed in all patients. Tissue samples were sent for Ziehl Neelson (ZN) stain, GeneXpert Ultra, histopathology and mycobacterial culture (BACTEC). The sensitivity, specificity, positive predictive value (PPV), and Negative predictive value (NPV) of GeneXpert Ultra were analysed in comparison with culture results.ResultsA total of 85 patients Lymph node were included, of which 60% (n=51) had cervical LN, 15%(n=13) abdominal LN, 12%(n=11) mediastinal LN, and 15%(n=11) others. Most of the patients (97%) HPE findings of granulomatous inflammation of which only 20%(n=17) were ZN stain Positive. TB culture showed positivity of 56.47%(n=48) . Mycobacterial tuberculosis was detected in 69%(n=59) of patients by GeneXpert Ultra & none of them showed Rifampicin resistance. The Sensitivity, specificity, PPV & NPV for GeneXpert Ultra were found 85.4%, 51.3%, 25.06% and 94.8%, respectively.ConclusionGeneXpert Ultra showed excellent sensitivity and negative predictive value for the diagnosis of TB Lymphadenitis. Further this method detects Rifampin sensitivity which is crucial for initiation of appropriate antitubercular drugs.Disclosures All Authors: No reported disclosures.

The molecular method like GeneXpert has significantly improved the diagnosis of TB. GeneXpert Ultra is more sensitive to the diagnosis and helps in paucibacillary samples like cerebrospinal fluid (CSF). This study aims to provide its utility in diagnosis of central nervous system tuberculosis (CNS TB) in high TB burden geography. Methods This prospective observational study included the suspected cases of CNS TB with age ≥12 years. Patients who presented with ≥ 5 days history of CNS symptoms suggestive of tuberculosis with a lancet score of ≥ 6 on combination of clinical, CSF and imaging criteria were included in the study. Patients diagnosed with aetiology other than tuberculosis for CNS disease were excluded. CSF was analysed for GeneXpert Ultra and mycobacterial culture. The sensitivity, specificity, positive predictive value (PPV), and Nega...

Post the outbreak of COVID-19, these fungal osteomyelitis have seen a global rise with few atypical presentations noted. Case report Current case series reports three such atypical presentations of fungal osteomyelitis including mandibular fungal osteomyelitis in two patients, fungal osteomyelitis mimicking space infection in a middle aged male, and suspected mixed fungal osteomyelitis involving maxillary sinus. Aggressive surgical debridement was indicated along with institution of antifungal therapy (Liposomal Amphotericin B, and Posaconazole). The fungal osteomyelitis was successfully treated with surgical and medical management with no recurrence. Discussion The injudicious use of corticosteroids in COVID-19 patients along with their immunocompromised status increases their susceptibility to opportunistic fungal osteomyelitis. Prompt and aggressive surgical intervention along with antifungal therapy is important after diagnosing fungal osteomyelitis, as a delay could increase the mortality rate considerably.

A 55 year old G 2 P 1 female being treated for abnormal uterine bleeding presented with fever, paresthesia, altered sensorium, headache and progressive loss of vision in both eyes. She was referred for neurocysticercosis on account of multiple intracranial space occupying lesions and was subsequently diagnosed to have cerebral toxoplasmosis through stereotactic brain biopsy and imaging, finally leading to the diagnosis of HIV infection. Such patients with unknown immunocompromised status in low HIV-prevalence developing countries may present late on account of seeking delayed medical attention. Cerebral toxoplasmosis is an asymptomatic latent infection known to lead to the diagnosis of HIV infection.

The association of isolated renal mucormycosis in a patient with a history of COVID-19 infection is unknown. The immune dysregulation associated with COVID, along with the use of steroids, mechanical ventilation, and interleukin-6-directed therapies, predisposes to the development of mucormycosis. We report a rare case of primary renal mucormycosis in a young male following recovery from COVID-19. The unusual mode of presentation, rapidly progressive disease course, and the ensuing dilemmas in diagnosis and treatment merit critical analysis.

Fever and changing heart murmur are the most common clinical manifestations. The diagnosis of fungal endocarditis is challenging, especially that of prosthetic valve endocarditis is extremely difficult. The optimal management of the condition still remains debatable. We hereby present a case of prosthetic valve endocarditis caused by Candida parapsilosis , managed empirically with liposomal amphotericin B and later on was shifted to combination therapy with high dose echinocandin and fluconazole, but had a fatal outcome because he could not undergo timely surgical intervention. Treating Candida parapsilosis endocarditis cases are difficult because of their ability of biofilm production on native and prosthetic heart valves. A combined approach consisting of high index of clinical suspicion, early diagnosis by using serological markers followed by culture or ...

Early diagnosis and prompt treatment improve patient survival. The gold standard method—conventional microscopy and culture have low sensitivity and a long turnaround time. Serum Galactomannan (GM), a polysaccharide that forms a major component of Aspergillus cell wall and is released by the fungus during invasive growth is established as a reliable biomarker, which is available as Enzyme Linked Immunoassay (ELISA). The limitations of ELISA are high cost, expertise, and difficulty in assay standardization. To overcome these limitations, a qualitative Galactomannan Lateral Flow Assay (GM-LFA) a sandwich immunochromatographic test, recently approved by European CE, is evaluated in our study. Objective To establish the diagnosis of Invasive Aspergillosis according to EORTC/MSGERC Definitions of Invasive Fungal ...

But, recently increasing cases have been reported in patients with non-classical risk factors and non-neutropenic patients like diabetes mellitus, chronic lung disease, HIV infection, critically ill patients, etc. According to ISHAM these non-classical risk factors should be included in EORTC/MSG host criteria for diagnosis of invasive aspergillosis. India has a high tuberculosis (TB) burden, and this is always considered as the first differential for any patient with fever, cough, hemoptysis, and weight loss. Post-tubercular chronic pulmonary aspergillosis common reported condition. However, co-infection of active TB and invasive aspergillosis is less reported. This co-infection could be one of the contributors of high morbidity and mortality in cases with tuberculosis. We hereby present a ser...

It can cause a wide array of clinical manifestation, which includes meningitis, pulmonary, as well as disseminated infection. Cryptococcus neoformans causes more than 90% cases of cryptococcal meningitis. Methodology We performed a retrospective review of patients with confirmed cryptococcal meningitis during 1 year period from 2021 to 2022 in tertiary care center, AIIMS Jodhpur. We assessed clinical, radiological, microbiological, and biochemical parameters along with treatment provided and outcomes of the patient. Results Of 189 patients screened for suspected cryptococcal meningitis, 6 were microbiologically confirmed positive. All the patients were immunocompromised, of which four were HIV positive and one was a solid organ transplant recipient on immunosuppression an...

Among the Mucorales, maximum cases have been reported among Mucor spp. and Rhizopus spp. Case: Here we present a case of a 9-year-old immunocompetent child presenting with abdominal pain and distension of 1-month duration followed by swelling of bilateral lower limbs, which was gradual in onset. Ultrasonography of the abdomen and pelvis was done which revealed a pelvic mass on the left side. The child developed acute urinary retention during the hospital stay, which was evaluated to reveal a fistulous connection between urethra and rectum for which transverse colostomy was done. The USG-guided biopsy of the left pelvic mass showed broad aseptate hyphae in Hematoxylin and Eosine staini...

Treatment with 5% vancomycin eye drops led to healing of corneal ulcer followed by scar formation. Fresh corneal graft transplanted after three months resulted in clear graft well opposed to the host cornea accompanied with visual acquity of 6/24 and -2 170° refractive correction. While viridans Streptococci have been implicated in corneal infections, this is the first case of S. mitis/oralis corneal ulcer of its kind. S. mitis/oralis is expanding in pathogenicity crossing the barriers of commensalism to cause opportunistic infection in susceptible hosts. It is difficult to identify and differentiate it to species level through conventional, molecular and mass spectrometry due to limitations of phenotypic expression, genotypic sequence and spectra databases. Both penicillin and high level gentamicin resistance has been reported. S. ...

It has been shown to spread through respiratory droplets, direct contact and environmental fomites. The possibility of its spread by other modes viz. airborne, fecal-oral, vertical, etc. is being explored and can have implications in planning preventive strategies and disease management. A systematic analysis was carried out using the keywords; “COVID 19 vertical transmission”, “SARS-CoV-2 pregnancy”, and “SARS-CoV-2 vertical transmission”, and the cases suggestive of possible vertical transmission of SARS-CoV-2 were studied in detail. The available evidences point at a possibility of vertical transmission of SARS-CoV-2. (www.actabiomedica.it)
