RESUMO
Arterial involvement, although rare, accounts for significant mortality and morbidity in patients of Behçet's disease (BD). There is paucity of data on arterial BD. The objective of this 5-year retrospective cohort study was to examine the clinical presentation, pattern of arterial involvement, and treatment outcome in Indian arterial BD patients. Data on demography, clinical presentation, radiology, instituted therapy, vascular interventions and treatment outcomes were recorded and analyzed. Ten (16.9%) out of 59 patients with BD had arterial involvement in 13 vascular territories [mean age 30 (8) years, 9 (90%) males]. Pulmonary artery was most commonly involved (46%), followed by abdominal aorta (15%), femoral artery (15%), descending thoracic aorta (8%), common iliac (8%), and dorsalis pedis artery (8%). Two patients had multi-territory involvement. The median interval between disease onset and development of arterial aneurysms was 3 years (3 months-12 years). Concomitant deep vein thrombosis was seen in 60% cases. Prednisolone and cyclophosphamide were the most common immunosuppressive therapy used; one patient who relapsed on cyclophosphamide responded to infliximab. Five surgical or endovascular interventions were performed. Four patients (40%) died due to aneurysm rupture-all had a delayed diagnosis, and three had pulmonary artery involvement, with death due to massive hemoptysis. Based on the present study, we concluded that arterial involvement in BD is seen predominantly in males and has a high mortality. Early detection and aggressive treatment with immunosuppression and surgical or endovascular interventions are essential for good outcomes.

RESUMO
PURPOSE: No study has compared neurally adjusted ventilator assist (NAVA) with adaptive support ventilation (ASV) during non-invasive ventilation (NIV) in subjects with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). MATERIALS AND METHODS: In this randomized controlled trial, we compared NAVA-NIV with ASV-NIV for delivering NIV in consecutive subjects with AECOPD. The primary outcome was NIV failure rate (invasive mechanical ventilation). The key secondary outcomes were number of NIV manipulations, asynchrony index, and 90-day mortality. RESULTS: We enrolled 76 subjects (NAVA-NIV, n = 36, ASV-NIV, n = 40; 74% males) with a mean ± SD age of 61.4 ± 8.2 years. We found no difference in NIV failure rates between the two arms (NAVA-NIV vs. ASV-NIV; 8/36 [22.2%] vs. 8/40 [20%]; p = 0.83). The median physician manipulations for NIV were significantly less in the ASV-NIV arm than in the NAVA-NIV arm (2 [0.8-4] vs. 3 [2-5]; p= 0.014) during the initial 24-h. We found no difference in median asynchrony index (NAVA-NIV vs. ASV-NIV, 16.6% vs. 16.4%, p = 0.5) and 90-day mortality (22.2% vs. 17.5%, p = 0.67). CONCLUSION: The use of NAVA-NIV was not superior to ASV-NIV in reducing NIV failure rates in AECOPD. Both NAVA-NIV and ASV-NIV had similar asynchrony index and 90-day mortality. TRIAL REGISTRY: www.

Necrotising fasciitis is a dreaded aggressive soft tissue infection that can cause extensive tissue necrosis. It may arise in the breast where its diagnosis may not readily be evoked.

Hypoxaemia in COVID-19 does not necessarily imply COVID pneumonia or post-COVID lung fibrosis, and the caveats of finger pulse oximetry should be remembered. Drug-induced methaemoglobinemia should be considered in individuals with unexplained cyanosis, refractory hypoxaemia, or the presence of a saturation gap. Here, we share our recent encounter of 'spurious hypoxia' in a patient with COVID-19 and methaemoglobinemia.

A 30-year-old man presented with fever, hepatosplenomegaly, and a rash over his lower limbs (palpable purpura). Evaluation revealed pancytopenia and hypergammaglobulinemia. A subsequent bone marrow examination and serology confirmed visceral leishmaniasis (kala-azar), while the biopsy of skin lesion suggested leukocytoclastic vasculitis. No alternate cause of vasculitis was forthcoming, and the patient was treated with conventional amphotericin B for 14 days after which resolution of symptoms (including the rash) was noted. Cutaneous vasculitis is an extremely rare complication following visceral leishmaniasis with no known cases reported thus far. Hence, a high index of suspicion is warranted in achieving timely diagnosis and initiation of appropriate therapy.
RESUMO
INTRODUCTION: Organophosphate (OP) poisoning is an important public health concern in South-Asia especially in the farming population. Treatment of OP poisoning has remained unchanged since decades and case fatality is 10-40% despite best supportive care, anticholinergic agents and oximes. A new antidote is the need of the hour. Lipid emulsion being inexpensive, easily available and effective in management of other lipid soluble toxins may be a novel option. However, safety has not been established and efficacy is limited to animal studies and case reports in humans with OP poisoning. METHODS: An open-label pilot study was undertaken to establish the safety of lipid emulsion in OP poisoning. Patients with symptomatic OP poisoning, meeting the inclusion and exclusion criteria were treated with 100 mL of 20% intravenous lipid emulsion (after consent) in addition to standard of care. They were monitored for change in hemodynamic parameters, change in hematology and biochemical parameters at various intervals of time after initiation of therapy. Morbidity, mortality, and occurrence of adverse effects were compared with historical control group. RESULTS: Forty patients with symptomatic OP poisoning were enrolled in the study group. No significant change in hemodynamic parameters (pulse rate, systolic, diastolic blood pressure, and mean arterial pressure) or in hematology and biochemical parameters were seen. No adverse effects were noted. Compared to historical controls, no change in mortality was noted, although there was reduced duration of mechanical ventilation, hospital stay, and early resolution of hypernatremia. CONCLUSIONS: This study evaluates the safety of lipid emulsion in OP poisoning. Absence of change in hemodynamic parameters and adverse effects suggests lipid emulsion may be safe for this indication. Large randomized controlled trials are now required to assess clinical efficacy. ClinicalTrials.gov number: NCT03564574.

Tubercular splenic abscess is extremely rare, but are reported commonly in HIV-positive and immunocompromised patients along with miliary or disseminated tuberculosis. Isolated tubercular splenic abscess in an immunocompetent individual is rarely reported. Here we present a case of a young, immunocompetent male with isolated splenic cold abscesses, who was diagnosed with splenic tuberculosis and managed successfully with percutaneous drainage and anti-tubercular therapy alone.
RESUMO
A 19-year-old woman presented with a history of severe lower backache and asymmetric proximal lower limb weakness during the past 3 months. In addition, she also suffered from lower motor neuron-type bladder and bowel symptoms. On examination, paraparesis was noted. Further, sensory examination suggested patchy asymmetric sensory loss in both lower limbs with saddle anaesthesia and areflexia. A clinical diagnosis of Conus-Cauda syndrome was made and contrast-enhanced MRI of the lumbar and sacral spine was done, which confirmed the presence of a mass lesion within the spinal canal involving the cauda equina extending up to the sacral level. She underwent partial resection of the lesion following which the neurological deficits and lower backache resolved. Histopathological evaluation and immunohistochemical analyses uncovered Rosai-Dorfman disease. There was no evidence of disease elsewhere in the body. Since the patient improved significantly following surgery and exhibited no further neurological worsening, she remains under close follow-up.

Mediastinal cysts are mostly congenital, but rarely, infections and malignancies can cause cystic degeneration of enlarged mediastinal lymph nodes. Diagnosis is challenging as the presenting symptoms are nonspecific. Surgical resection is the reference modality both for diagnosis and management. Secondary infection of mediastinal bronchogenic cyst with Mycobacterium tuberculosis is rare. Herein, we describe a young male who was managed as bronchial asthma with inhalational bronchodilators and glucocorticoids. Computed tomography revealed a cystic lesion in the subcarinal region. Endobronchial ultrasound-guided transbronchial needle aspiration was done to perform diagnostic and therapeutic aspiration of the cyst that showed infection with M. tuberculosis. A subsequent surgical resection confirmed the cystic lesion to be a bronchogenic cyst.
