RESUMEN
Background: There has been an increase an alarming rise in invasive mycoses during COVID-19 pandemic, especially during the second wave. Aims: Compare the incidence of invasive mycoses in the last three years and study the risk factors, manifestations and outcomes of mycoses in the COVID era. Methodology: Multicentric study was conducted across 21 centres in a state of western India over 12-months. The clinico-radiological, laboratory and microbiological features, treatment and outcomes of patients were studied. We also analysed yearly incidence of rhino-orbito-cerebral mycosis. Results: There was more than five-times rise in the incidence of invasive mycoses compared to previous two-years. Of the 122 patients analysed, mucor, aspergillus and dual infection were seen in 86.9%, 4.1%, and 7.4% respectively. Fifty-nine percent had simultaneous mycosis and COVID-19 while rest had sequential infection. Common presenting features were headache (91%), facial pain (78.7%), diplopia (66.4%) and vison loss (56.6%). Rhino-orbito-sinusitis was present in 96.7%, meningitis in 6.6%, intracranial mass lesions in 15.6% and strokes in 14.8%. A total of 91.8% patients were diabetic, while 90.2% were treated with steroids during COVID-19 treatment. Mortality was 34.4%. Conclusion: Invasive fungal infections having high mortality and morbidity have increased burden on already overburdened healthcare system. Past illnesses, COVID-19 itself and its treatment and environmental factors seem responsible for the rise of fungal infection. Awareness and preventive strategies are the need of hours and larger studies are needed for better understanding of this deadly disease.
RESUMEN
INTRODUCTION: Cerebral Sino-Venous thrombosis (CSVT) is common in India; this country has a heterogeneous population. Genetically and physio-gnomically this population differs in their diet as well as in their environment. Despite these differences CSVT has been described from all quarters of India; a common factor embracing all these patients could be nutrition. OBJECTIVES: An epidemiological, case- control, multi-centre trial was carried out in patients of CSVT. A common factor underlying this could be nutrition which has not been highlighted in several studies. Hence, we studied the nutritional aspects of these patients. METHOD: 63 patients of CSVT and 62 controls enrolled prospectively and followed for a year were investigated with special emphasis on their nutritional status. RESULTS: The triceps skin fold thickness, energy baseline, serum Proteins, Albumin, Hemogram and Platelet counts were lower in patients than in the controls while serum Homocysteine, carbohydrates and fats were higher in patients than in controls. CONCLUSION: The results of this study confirm nutritional deficiencies in patients of CSVT and it begs the question of whether nutrition in any way is causal in CSVT. Larger multi-centric trials will help establishing causality. The study also shows that routine evaluation of thrombophilia factors and immunological tests are not necessary in CSVT.

AIMS: To study and compare the electrophysiological changes in neuroparalytic or vasculotoxic snakebites. MATERIALS AND METHODS: 40 patients who had a definite history of snakebite, either vasculotoxic or neuroparalytic, were selected. They were grouped as Group A, 20 patients having a neuroparalytic snakebite with definite envenomation at the time of admission, and Group B, 20 patients having a vasculotoxic snakebite with definite envenomation at the time of admission. All patients underwent a detailed clinical examination, all relevant investigations and nerve conduction studies according to protocol. RESULTS: In this study, we noticed that the motor nerve conduction amplitude, conduction velocity and distal latency were within normal limits in both the groups. On RNS (repetitive nerve stimulation study) of facial and median nerves, a decremental response was seen in 13 (65%) patients in facial nerve and in 7 (35%) patients in median nerve in Group A; while, the same response was seen in 8 (40%) patients in facial nerve and 3 (15%) patients in median nerve in Group B. A post exercise decremental response was seen in 13 (65%) patients in median nerve and 16 (80%) patients in facial nerve in Group A; and, in 3 (15%) patients in median nerve and 8 (40%) patients in facial nerve in Group B. CONCLUSIONS: In our study, we noticed that the decremental response on RNS was not only present in neuroparalytic snake bite (post-synaptic neuromuscular blockade) but also in vasculotoxic snakebite [pre-synaptic neuromuscular blockade] (seen in Russel's viper).
RESUMEN
Hypertrophic pachymeningitis (HP) is a rare chronic inflammatory disease of the dura mater, described in association with various infections, systemic vasculitides such as Wegener's granulomatosis and giant cell arteritis. However, HP in association with Takayasu arteritis (TA) has not been described. We report a young woman who presented with headache, seizures, and right third and fourth cranial neuropathy. Magnetic resonance imaging of the brain showed HP in bifrontal and right temporal region extending to cavernous sinus. She was also found to have systemic hypertension, stenosis of left subclavian, and left renal artery with narrowing of abdominal aorta, satisfying the diagnostic criteria for TA. A detailed evaluation for secondary causes of HP failed to reveal an alternative etiology. This report describes an unusual association of HP in a patient with TA, also emphasizing that seizures and cranial neuropathy may further expand the spectrum of neurological manifestations in patients with TA.
