Yellow phosphorus or metal phosphide (YP-MP) rodenticide poisoning has been a known cause of acute liver failure (ALF) in many countries of Asia and North and South America over the last decade. It is a highly toxic compound and is a well-known cause of intentional or accidental poisoning in both adults and children. In lower doses, it causes gastrointestinal symptoms and mild hepatic injury, and patients may spontaneously recover.

Background: The coronavirus disease 2019 (COVID-19) pandemic has brought about radical changes in our habits and lifestyles. The suspension of schools has led children to spend long hours at home, with reduced socialization, and changes in dietary patterns, oral hygiene practices and sleep routines. During a pandemic, appropriate oral health management and disease prevention are very important for the child's oral and general health.

Importance: An outbreak of COVID-19-associated rhino-orbitocerebral mucormycosis (CAM) has occurred in many parts of the world. Although the clinical profile and risk factors for CAM have been studied, cumulative mortality and its risk factors have not.

Objective: To report the cumulative mortality rates at different times in cases with CAM and identify risk factors for CAM-associated mortality.

The COVID-19 pandemic has resulted in widespread use of complementary and alternative medicines. Tinospora cordifolia is a widely grown shrub which has been commonly used in India's traditional system of Ayurveda for its immune booster properties and has been extensively used as prophylaxis against COVID-19. Six patients (4 women, 2 men) with a median (IQR) age of 55 years (45-56) and with an history of Tinospora cordifolia consumption presented with symptoms of acute hepatitis during the study period of 4 months in the COVID-19 pandemic.

Unlabelled: Many of the neurons in early visual cortex are selective for the orientation of boundaries defined by first-order cues (luminance) as well as second-order cues (contrast, texture). The neural circuit mechanism underlying this selectivity is still unclear, but some studies have proposed that it emerges from spatial nonlinearities of subcortical Y cells. To understand how inputs from the Y-cell pathway might be pooled to generate cue-invariant receptive fields, we recorded visual responses from single neurons in cat Area 18 using linear multielectrode arrays.

Article Synopsis
  • Solitary fibrous tumours are rare growths of mesenchymal origin that usually occur in the pleura but can also develop in various other parts of the body, including the orbit.
  • A case study involving a 41-year-old man showed a painless mass in the left orbit causing eye displacement, with imaging suggesting possible lacrimal gland or nerve sheath tumours.
  • Following complete surgical excision, histopathological results indicated the presence of a solitary fibrous tumour with atypical features; however, no malignant characteristics were found, and the patient remained recurrence-free after 18 months.

Background And Objectives: The behavior of odontogenic lesions varies with some tumors behaving like a cyst and some cysts behaving like tumors. p63, a member of the p53 family of tumor suppressor genes has recently come into light in view of its role as an oncogene. The aim of the present study was to investigate the expression of p63 protein in OKC, Solid ameloblastoma, Unicystic Ameloblastoma and Follicular tissue.

Background: Percutaneous endoscopic gastrostomy (PEG) is the procedure of choice for long-term enteral feeding.

Objective: This prospective observational study was carried out to compare the safety of commencing feeding 3 h compared to 16-24 h after PEG tube placement.

Methods: One hundred and ten patients with oropharyngeal malignancies who had consented for PEG were enrolled.

Pseudomelanosis duodeni is a rare, benign condition of unknown etiology. It is characterized by collection of pigment-laden macrophages in the tips of duodenal villi. The pigment, originally interpreted as melanin, pseudomelanin, lipomelanin or hemosiderin, has now been demonstrated to be mostly ferrous sulfide.

Recent studies suggest that exposure to only one component of audiovisual events can lead to cross-modal cortical activation. However, it is not certain whether such crossmodal recruitment can occur in the absence of explicit conditioning, semantic factors, or long-term associations. A recent study demonstrated that crossmodal cortical recruitment can occur even after a brief exposure to bimodal stimuli without semantic association.

From our daily experience, it is very clear that relative motion cues can contribute to correctly identifying object boundaries and perceiving depth. Motion-defined contours are not only generated by the motion of objects in a scene but also by the movement of an observer's head and body (motion parallax). However, the neural mechanism involved in detecting these contours is still unknown.

Unlabelled: Guillain-Barre Syndrome (GBS) has an unpredictable clinical course with up to 30% of patients requiring assisted ventilation during the course of their illness. Successful management mandates anticipation, prompt recognition and optimal treatment of neuromuscular respiratory failure in GBS.

Aims: To identify clinical and electrodiagnostic predictors of neuromuscular respiratory paralysis in GBS.
