Objective: To evaluate the effect of propofol combined with psychological intervention on pain and emotional evaluation in painless colonoscopic colonic polypectomy patients undergoing endoscopic mucosal resection (EMR).Methods: A total of 80 patients who underwent painless colonoscopic colonic polypectomy with EMR treatment between June 2020 and June 2022 were selected in order of admission and divided into two groups. The control group received conventional analgesia, while the observation group received propofol combined with psychological intervention. Pain visual analog scale (VAS) and emotional scale were used to evaluate pain and emotions in both groups of patients. Adverse reactions and clinical efficacy were also compared between the two groups.Results: The two groups of patients were generally comparable with no significant differences (P > 0.05). The VAS score in the observation group was significantly lower than that in the control group (P < 0.05), and the emotional scale score was also improved compared to the control group (P < 0.05). The number of patients with adverse reactions in the observation group was less than that in the control group. The clinical effective rate in the observation group was significantly higher than that in the control group (P < 0.05).Conclusion: Propofol combined with psychological intervention can effectively alleviate pain and improve emotional status in painless colonoscopic colonic polypectomy patients undergoing EMR treatment, thereby increasing the comfort and success rate of the surgery. The number of patients with adverse reactions in the observation group was less than that in the control group, and the clinical effective rate in the observation group was significantly higher than that in the control group (P < 0.05).

Introduction: Acute compartment syndrome (ACS) is a surgical emergency that requires urgent intervention in order to prevent permanent structural damage and irreversible functional disability. The diagnosis of ACS depends on a high index of suspicion, relying on the following diagnostic criteria commonly known as the 5 Ps; Pain, Paresthesia, Paralysis, Pallor, and Pulse-lessness. When the diagnosis is uncertain, intracompartmental pressure greater than 30 mmHg is suggestive of ACS. Case Presentation: We report a case of an underdiagnosed ACS, with a lack of classical presentation in a thirty-seven-years-old male patient with a history of myopathy. The patient was admitted to the emergency room due to direct trauma to his right hip, without a significant Visual Analogue Score. On his hip radiograph a subtrochanteric fracture of the right femur was demonstrated. An additional masked ipsilateral subcapital fracture was detected during the operation. The diagnosis of ACS was made during the operation while relying on the clinical appearance of the thigh and the clinical findings during surgery. Fasciotomies were performed, and open reduction with internal fixation via Proximal Femoral Nail was done. The diagnosis of ACS was confirmed later on, by the biopsy results. Conclusion: This case suggests that myopathy can mask the classical presentation of ACS. Furthermore, the extent of pain complaints and accompanying paresthesia cannot be relied on in this regard and other clinical features should be considered in order to diagnose ACS.

Quantification of erythrocytes and leukocytes is an essential aspect of hemogram diagno- 23 sis in Veterinary Medicine. Flow cytometry analysis, laser scattering, and impedance detection are 24 standard laboratory techniques, verified by manual microscopy counting. Although single-cell scat- 25 tering is already used as a standard technology for differentiating cell counts in flow cytometry, it 26 requires capillary cell separation. The current study investigates the scattering characteristics of 27 whole blood to identify correlations with erythrocytes and leukocytes counts. The scattering infor- 28 mation present in blood samples can be classified into three types: i) geometrical scattering, which 29 occurs when non-absorbed light is reflected and scattered, ii) Mie scattering, which happens when 30 light is scattered by particles of a similar size to the wavelength, and iii) Rayleigh scattering, which occurs when light is scattered by particles that are smaller than the incident light wavelength. In 32 this study, we investigate the scattering correction coefficients of dog blood absorption spectra in 33 the visible-near infrared range, to establish direct correlations with erythrocytes and leukocytes 34 counts, using multivariate linear regression. Our findings demonstrate the possibility of using the 35 scattering properties of dog blood, which is a step towards the existence of a portable and miniatur- 36 ized hemogram diagnosis in Veterinary Clinics worldwide.
