The Utility of Galactomannan and Polymerase Chain Reaction Assays in Bronchoalveolar Lavage for Diagnosis of Chronic Pulmonary Aspergillosis.

The diagnosis of chronic pulmonary aspergillosis (CPA) is established by combined clinic-radio-microbiological criteria. Out of the different microbiological criteria, a positive serology for Aspergillus-specific IgG levels is the cornerstone of diagnosis. Alternatively, other microbiological evidence are sometimes sought viz., positive Aspergillus antigen (broncho-alveolar lavage fluid, i.e., BALF galactomannan ≥ 1.0), histopathological demonstration of the fungi following lung biopsy or resection, demonstration of hyaline septate hyphae in direct microscopy resembling Aspergillus spp. or its growth on a respiratory specimen. However, the exact roles of BALF- GM and the newer BALF-PCR have not been confirmed by studies till date. This study enrolled 210 patients with suspected CPA. Of the participants, 88 patients met the criteria for CPA, whereas 122 patients had an alternative diagnosis. The sensitivity-specificity of AsperGenius® PCR and "in-house" PCR were 52.27(36.69-67.54) %-33.78 (23.19-45.72) % and 36.36 (22.41-52.23) %-39.19 (28.04-51.23) % respectively. The sensitivity/specificity of BALF (> 1.0) and serum galactomannan (> 1.0) were 46.55% (33.34-60.13)/64.08% (54.03-73.3) and 29.82% (22.05-37.6)/86.84% (81.1-92.59) respectively. The optimal cut-off values for BALF-Galactomannan and serum galactomannan in diagnosing CPA were found to be 0.69 (sensitivity: 64%; specificity: 53%) and 0.458 (sensitivity: 67%; specificity: 64%) respectively. This results of this study suggests that Aspergillus PCR from BAL may not be a good "rule-in" test for diagnosing CPA. While the performances of GM in BAL and serum may be better than PCR, it should be best used in conjunction with other clinical, radiological, and other microbiological characteristics.

Extensive Metastatic Vascular Calcification in a Patient with Chronic Renal Failure and Tubercular Osteomyelitis as Seen on F-18 Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography.

A 48-year-old male with known tubercular osteomyelitis of the left elbow and chronic renal failure presented with PTH independent hypercalcemia and underwent F-18 fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) to look for any underlying malignancy that might be causing his hypercalcemia. The PET/CT did not reveal any malignancy, but extensive metastatic calcification of small- and medium-sized arteries was noted throughout the body with relative sparing of large vessels. Alkaline tissue such as lungs, gastric mucosa, and kidneys that are usually involved in metastatic calcification were also spared. The underlying pathology for this kind of metastatic calcification was most likely chronic granulomatous disease, which was tubercular osteomyelitis in this patient. We present the PET/CT scan images of this unusual case of metastatic vascular calcification.

Clinical profile of ChAdOx1 nCoV-19- and BBV152-vaccinated individuals among hospitalized COVID-19 patients: a pair-matched study.

Background: COVID-19 infections among severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-vaccinated individuals are of clinical concern, especially in those requiring hospitalization. Such real-world data on ChAdOx1 nCoV-19- and BBV152-vaccinated individuals are scarce. Hence, there is an urgent need to understand their clinical profile and outcomes. Methods: A 1:1 pair-matched study was performed among vaccinated and unvaccinated COVID-19 patients admitted between March 2021 and June 2021 at a tertiary care centre in New Delhi, India. The vaccinated group (received at least one dose of ChAdOx1 nCoV-19 or BBV152) was prospectively followed till discharge or death and matched [for age (±10 years), sex, baseline disease severity and comorbidities] with a retrospective group of unvaccinated patients admitted during the study period. Paired analysis was done to look for clinical outcomes between the two groups. Results: The study included a total of 210 patients, with 105 in each of the vaccinated and unvaccinated groups. In the vaccinated group, 47 (44.8%) and 58 (55.2%) patients had received ChAdOx1 nCoV-19 and BBV152, respectively. However, 73 patients had received one dose and 32 had received two doses of the vaccine. Disease severity was mild in 36.2%, moderate in 31.4% and severe in 32.4%. Two mortalities were reported out of 19 fully vaccinated individuals. All-cause mortality in the vaccinated group was 8.6% (9/105), which was significantly lower than the matched unvaccinated group mortality of 21.9% (23/105), p = 0.007. Vaccination increased the chances of survival (OR = 3.8, 95% CI: 1.42-10.18) compared to the unvaccinated group. Conclusion: In the second wave of the pandemic predominated by delta variant of SARS CoV-2, vaccination reduced all-cause mortality among hospitalized patients, although the results are only preliminary.

Utility of nasal application of lignocaine gel using cotton tip swab versus squirting with slip-tip syringe for transnasal fibreoptic bronchoscopy: a pilot randomised controlled trial.

BACKGROUND: During flexible fibreoptic bronchoscopy through the nasal route, anaesthesia of the nasal passage is achieved by lignocaine gel application by a slip-tip syringe or with the help of a cotton tip swab. No studies in existing literature have compared the two techniques in terms of efficacy. METHODS: 137 consecutive patients undergoing bronchoalveolar lavage (BAL) were recruited over a 2-year period. The patients underwent BAL after nasal anaesthesia-either by slip-tip syringe or by cotton tip swab smeared with 2% lignocaine gel. Patients were monitored for intraprocedural epistaxis, discomfort and improvement in operator visibility of nasal passage. RESULTS: 67 patients were randomised to cotton swab and 70 patients to the gel instillation group. There were no significant differences in terms of epistaxis, 29.9% in the cotton tip swab (95% CI 19.3% to 42.3%) versus 24.3% in the gel instillation group (95% CI 14.8% to 36%) or detection of nasal blocks, 7.5% in the cotton tip swab (95% CI 2.5% to 16.6%) versus 10% in the gel instillation group (95% CI 4.1% to 19.5%) in the two groups, although a significant difference was there in terms of visibility, 73.1% in the cotton tip swab (95% CI 60.9% to 83.2%) versus 42.9% in the gel instillation group (95% CI 31.1% to 55.3%). There was no difference in the mean pain score across the two groups either during the procedure or 1 hour after it. A short systematic review of existing literature on the topic has been provided for comparison. CONCLUSION: Application of 2% lignocaine gel by slip-tip syringe and cotton tip swab are equivalent in terms of observed and narrated pain experienced by patients, frequency of epistaxis and nasal blocks. Vision was better preserved in the cotton tip swab group.

B Cell ALL with Pyrexia of Unknown Origin, Masquerading as Inflammatory Arthritis.

ABSTRACT: We present a young male, with long standing fever, weight loss, bone pains, hepatosplenomegaly, cytopenias and severe joint pains. With normal peripheral smear and predominant joints involvement, he was started on corticosteroids. The partial response prompted the physician to continue the steroids. After some time, however, joints and bony pains worsened. After referral to us, he was found to have multiple bony lytic lesions and peripheral smear suggested B cell ALL. So, presentation predominantly with musculoskeletal symptoms, a normal peripheral smear and a partial therapeutic response to steroids as treatment of Systemic Juvenile Idiopathic Arthritis, delayed the diagnosis significantly leading to complications. So through our report we would like to stress that suspecting and diagnosing leukaemia early is important to prevent complications and resistance to treatment. An early bone marrow examination should also be instituted as a standard of care in peripheral smear negative patients.

Necrobiotic Xanthogranuloma as the Presenting Manifestation of Smouldering Myeloma.

Necrobiotic xanthogranuloma is a rare dermatological manifestation of underlying hematological malignancies, in particular, when associated with paraproteinemia. These patients who are clinically symptomatic with chronic papules, nodules or plaques which demonstrate a histopathological pattern suggestive of extensive and frequently confluent areas of necrobiosis with granulomatous infiltration, warrant evaluation for an underlying monoclonal gammopathy.

Erythema Nodosum Leprosum as a Rare and Challenging Cause of Pyrexia of Unknown Origin.

A 30-year old male presented with fever for last 1 year. There were associated multiple painful skin eruptions with hyperpigmentation and scaling over whole body which had been progressively increasing. He also had anasarca along with generalized weakness. He presented to us in shock after an acute episode of gastroenteritis. After stabilization, he was evaluated for cause of fever. Routine fever workup (for typhoid, syphilis, malaria, filariasis, HIV, scrub typhus, leishmaniasis) was negative. CECT chest and abdomen revealed hepatosplenomegaly. There was no response to intravenous (IV) antibiotics and anti-fungal medications. Slit skin smears revealed 3+ acid fast bacilli (AFB). Skin biopsy revealed fragmented acid-fast bacilli with dense collection of neutrophils and foamy histiocytes in upper and middle dermis suggestive of Erythema Nodosum Leprosum (ENL). A diagnosis of ENL with lepromatous leprosy was made and patient started on steroids and thalidomide and subsequently on multidrug therapy (MDT). On therapy, patient's symptoms improved, and skin lesions resolved. Though Leprosy itself is a well-known common cause of PUO in India, its first presentation as ENL is rare and needs good index of suspicion and timely management.

A Catastrophic Presentation of Enteric Fever with Secondary Hemophagocytic Lymphohistiocytosis.

A 19 year old boy presented to the emergency room with fever of one week duration along with bleeding manifestations, few gastrointestinal symptoms, tachycardia, tachypnea and subtle encephalitic features. He was worked up for the usual causes of short duration fever, which proved inconclusive. In view of clinical worsening and cytopenias, a careful investigation process helped us in ruling out common etiologies for such a fever, alongwith unearthing the possibility of an underlying secondary hemophagocytic lymphohistiocytosis which led to severe thrombocytopenia and persistent high grade pyrexia. Widal test was positive in high titres, and patient was continued with antibiotics. Prompt treatment led to the uneventful recovery of the patient without any sequelae. Bleeding manifestations subsided, patient had rapid clinical improvement and was discharged after completing the course of antibiotics.

Plasma Cell Disorders in HIV Infected Patients: A Case Series.

People Living with HIV (PLHIV) are at an increased risk of developing malignancies. Plasma cell disorders are also reported with increased incidence in PLHIV compared to the general population. Here, we describe three different plasma cell disorders among PLHIV and highlight their atypical presentations and outcomes in these subjects.

Pheochromocytoma and tetralogy of Fallot: Coincidence or a rare association?

We report the case of a 25-year-old woman with tetralogy of Fallot who presented with chest pain and hypertension, and on further investigation, was diagnosed with a pheochromocytoma in the right adrenal gland. She underwent surgical excision of the tumor. While the simultaneous occurrence of these two diseases is extremely rare, the suspicion of a possible relationship has been raised in the past.

Consensus and evidence-based Indian initiative on obstructive sleep apnea guidelines 2014 (first edition).

Obstructive sleep apnea (OSA) and obstructive sleep apnea syndrome (OSAS) are subsets of sleep-disordered breathing. Awareness about OSA and its consequences among the general public as well as the majority of primary care physicians across India is poor. This necessitated the development of the Indian initiative on obstructive sleep apnea (INOSA) guidelines under the auspices of Department of Health Research, Ministry of Health and Family Welfare, Government of India. OSA is the occurrence of an average five or more episodes of obstructive respiratory events per hour of sleep with either sleep-related symptoms or co-morbidities or ≥15 such episodes without any sleep-related symptoms or co-morbidities. OSAS is defined as OSA associated with daytime symptoms, most often excessive sleepiness. Patients undergoing routine health check-up with snoring, daytime sleepiness, obesity, hypertension, motor vehicular accidents, and high-risk cases should undergo a comprehensive sleep evaluation. Medical examiners evaluating drivers, air pilots, railway drivers, and heavy machinery workers should be educated about OSA and should comprehensively evaluate applicants for OSA. Those suspected to have OSA on comprehensive sleep evaluation should be referred for a sleep study. Supervised overnight polysomnography is the "gold standard" for evaluation of OSA. Positive airway pressure (PAP) therapy is the mainstay of treatment of OSA. Oral appliances (OA) are indicated for use in patients with mild to moderate OSA who prefer OA to PAP, or who do not respond to PAP or who fail treatment attempts with PAP or behavioral measures. Surgical treatment is recommended in patients who have failed or are intolerant to PAP therapy.

Consensus & evidence-based INOSA Guidelines 2014 (first edition).

Obstructive sleep apnoea (OSA) and obstructive sleep apnoea syndrome (OSAS) are subsets of sleep-disordered breathing. Awareness about OSA and its consequences amongst the general public as well as the majority of primary care physcians across India is poor. This necessiated the development of the INdian initiative on Obstructive sleep apnoea (INOSA) guidelines under the auspices of Department of Health Research, Ministry of Health & Family Welfare, Government of India.

Medical examiners evaluating drivers, air pilots, railway drivers and heavy machinery workers should be educated about OSA and should comprehensively evaluate applicants for OSA. Those suspected to have OSA on comprehensive sleep evaluation should be referred for a sleep study. Supervised overnight polysomnography (PSG) is the "gold standard" for evaluation of OSA. Positive airway pressure (PAP) therapy is the mainstay of treatment of OSA. Oral appliances are indicated for use in patients with mild to moderate OSA who prefer oral appliances to PAP, or who do not respond to PAP or who fail treatment attempts with PAP or behavioural measures. Surgical treatment is recommended in patients who have failed or are intolerant to PAP therapy.
