Endoscopic management of surgical complications.

While the endoscopic management of surgical complications like leaks, fistulas, and perforations is rapidly evolving, its core principles revolve around closure, drainage, and containment. Effectively managing these conditions relies on several factors, such as the underlying cause, chronicity of the lesion, tissue viability, co-morbidities, availability of devices, and expertise required to perform the endoscopy. In contrast to acute perforation, fistulas and leaks often demand a multimodal approach requiring more than one session to achieve the required results. Although the ultimate goal is complete resolution, these endoscopic interventions can provide clinical stability, enabling enteral feeding to lead to early hospital discharge or elective surgery. In this discussion, we emphasize the current state of knowledge and the prospective role of endoscopic interventions in managing surgical complications.

Pictorial essay: Computed tomography findings in acute aortic syndromes.

Acute aortic emergencies are life-threatening conditions that may require urgent surgical or interventional management. Imaging plays an important role in the diagnosis and planning of the management, and timely intervention helps in reducing mortality and morbidity.

Dissipation pattern and risk assessment studies of triazophos residues on capsicum (Capsicum annuum L.) using GLC-FPD and GC-MS.

The present study was carried out to observe the dissipation pattern of triazophos on capsicum and risk assessment of its residues on human beings and to suggest a waiting period for the safety of consumers. Following two applications of triazophos (Truzo 40 EC) at 500 and 1000 g a.i. ha(-1), the average initial deposits were found to be 3.61 and 6.26 mg kg(-1), respectively. These residues dissipated below the limit of quantification (LOQ) of 0.05 mg kg(-1) in 10 and 15 days at the recommended and double the recommended dosages, respectively. The calculated values of half-life were 2.31 and 2.14 days at recommended and double the recommended dosages, respectively. Theoretical maximum residue contribution (TMRC) values were found to be 28.8 and 41.6 µg person(-1) day(-1) at 500 and 1000 g a.i. ha(-1), respectively, and found to be below the maximum permissible intake on capsicum fruit on the 7th day. Therefore, a waiting period of 7 days is suggested for consumption of capsicum sprayed with triazophos at the recommended dosages.

Persistence and risk assessment of cypermethrin residues on chilli (Capsicum annuum L.).

The study was conducted to observe the persistence pattern and risk assessment of cypermethrin in chilli fruits following three applications of cypermethrin (Super fighter 25 EC) at 50 and 100 g a.i. ha(-1) at 10-day interval. Residues of cypermethrin in chilli were estimated by gas liquid chromatography (GLC) and were confirmed by gas chromatography-mass spectrometry (GC-MS). The average initial deposits of cypermethrin in chilli fruits were found to be 1.46 and 3.11 mg kg(-1), at recommended and double the recommended dosages, respectively, following third application of the insecticide. Half-life periods for cypermethrin were found to be 4.43 and 4.70 days at recommended and double the recommended dosages, respectively. Residues of cypermethrin declined below its limit of quantification (LOQ) of 0.05 mg kg(-1) after 25 days at both the application dosages. Theoretical maximum residue contribution (TMRC) values were calculated from the residue data generated and were found to be below maximum permissible intake (MPI) even on 0 day. Therefore, according to our risk assessment studies, a waiting period of 1 day is suggested for consumption of chilli sprayed with cypermethrin at the recommended dosages.
