Recent emergence of the SARS‐CoV‐2 variant as OMICRON has become a global concern. This short note highlights the identification and global spread of OMICRON which has spread over 77 nations by now, which resulted in many hypotheses about its origin and degree of infectivity. The detection of mutations in the RBD region of Spike protein is a concern by surpassing vaccine immunity. The ahead will speak about its transmission potentiality, infectivity, disease morbidity as well as its effect on COVID‐19 vaccines.
Coronavirus Disease 19 (COVID-19), due to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has become an on-going global health emergency affecting over 94 million cases with more than 2 million deaths globally. Primarily identified as atypical pneumonia, it has developed into severe acute respiratory distress syndrome (ARDS), a multi-organ dysfunction with associated fatality. Ever since its emergence, COVID-19 with its plethora of clinical presentations has signalled its dynamic nature and versatility of the disease process. Being a disease with droplet transmission has now assumed the proportion of a suspected airborne nature which, once proved, poses a Herculean task to control. Because of the wide distribution of the human angiotensin-converting enzyme-2 (hACE2) receptors, known for its transmission, we envisage its multiorgan spread and extensive disease distribution. Thus, an extensive review of the extrapulmonary organotropism of SARS-CoV-2 with organ-specific pathophysiology and associated manifestations like dermatological complications, myocardial dysfunction, gastrointestinal symptoms, neurologic illnesses, hepatic and renal injury is needed urgently. The plausible mechanism of site-specific viral invasion is also discussed to give a comprehensive understanding of disease complexity, to help us to focus on research priorities and therapeutic strategies to counter the disease progression. A note on the latest advancements in vaccine research will enlighten the scientific world and equip it for better preparedness.
Neurocysticercosis is a major cause of neurologic illness worldwide. Its manifestations are variable, and somewhat different when it occurs in children. Controversy exists regarding anticysticercal therapy. The clinical, laboratory, and radiographic features of 500 consecutive children with neurocysticercosis were studied; the children were then followed prospectively and their response to albendazole therapy was analyzed. Diagnosis of neurocysticercosis was based primarily on neuroimaging. Computed tomographic (CT) scans, neurocysticercosis serology, chest radiographs, and Mantoux tests were done in all children, and magnetic resonance imaging scans in 10%. All children with multiple lesions, and some randomly allocated children with single, small, enhancing CT lesions received albendazole. CT scans were repeated after 3 to 6 months. There were 272 boys and 228 girls, age range 16/12 to 126/12 years. Seizures were present in 94.8% of cases; 83.7% had focal seizures. Features of raised intracranial pressure were seen in 30% of patients and focal neurodeficit in 4%. Single lesions were seen in 76% of the children, with perilesional edema in 57.4%. Thirty-four children who had multiple cysts and received albendazole underwent serial CT evaluation. Four showed disappearance of lesions and 22 had reductions in the size or number, to give an overall improvement rate of 76%. Serial CT studies were available on 176 children with single lesions, 90 of whom received albendazole. Improvement (disappearance or reduction in the size of lesions) was observed in 91% (82 of 90) of albendazole-treated children versus 85% (73 of 86) of untreated children. This difference was not significant. No significant side-effects of albendazole were reported. These data indicate that partial seizures and single parenchymal cysts are the most frequent clinical and neuroradiographic manifestations of neurocysticercosis in children. Although albendazole therapy should be considered, especially in children with multiple lesions, many children with isolated neurocysticercosis will improve without antiparasitic therapy.
