We evaluated the effects of guanosine 5′-monophosphate (GMP)-chelated calcium and iron (CaFe-GMP) on health and egg quality in layers experimentally infected with Salmonella Gallinarum. In this study, a CaFe-GMP feed additive was added to a commercial layer feed and fed to layers over a four-week period. All were inoculated with Salmonella Gallinarum. Body weight, mortality, clinical symptoms, and poultry production including feed intake, egg production, egg loss, and feed conversion rate were observed, and Salmonella Gallinarum was re-isolated from the liver, spleen, and cecum of the layers. All tested internal organs for the CaFe-GMP additive group exhibited significantly lower re-isolation numbers of Salmonella Gallinarum and less severe pathological changes than those in the control group, indicating that the CaFe-GMP feed supplement induced bacterial clearance and increased resistance to Salmonella Gallinarum. Additionally, due to the inhibitory action of CaFe-GMP on the growth of Salmonella Gallinarum, the CaFe-GMP additive group exhibited better egg production, including a higher laying rate and fewer broken eggs. The results suggest that a 0.16% CaFe-GMP additive may help prevent salmonellosis in the poultry industry.

Idiopathic intracranial hypertension, a syndrome of obscure origin, occurs particularly in fat adolescent girls and young women. The usual symptoms are headache, blurred vision, a vague dizziness, horizontal diplopia and transient visual obscurations etc., and ophthalmoscopic examination reveals papillederma, due to increased ICP. Visual field testing usually shows slight peripheral constrictions with enlargement of the blind sports. CSF pressure is elevated in the range of 250 to 450 mm of water. Radiological or the other laboratory tests show no specific abnormalities. Treatment for idiopathic intracranial hypertension is focused on early detection and prevention of vision loss, the only permanent morbidity. Many different modes of medical treatment, including weight reduction, repeated lumber puncture, corticosteroids, diuretics, glycerol or carbonic anhydrase inhibitors, have successfully been tried up to 90% of the patients. In the remaining patients, particularly in those with measurable impairment of vision that does not respond to conventinal medical therapies, surgical procedure should be considered. We report a case of idiopathic intracranial hypertension successfully treated with optic nerve sheath fenestration.

This study aimed to investigate the concentrations of nonpersistent endocrine-disrupting chemicals (EDCs) and per- and polyfluoroalkyl substances (PFAS) in human milk through a literature review and to affirm the association between EDCs and lifestyle factors based on the reviewed literature. We analyzed studies reporting EDC concentrations in breast milk from literature published on Google Scholar and PubMed between 2000 and 2022. In Korea, most EDC concentrations in breast milk were comparable to or lower than those in other countries. However, the concentrations of PFAS in breast milk, especially perfluorooctanoic acid, have shown an increasing trend compared to the past in Korea. Considering the potential risks of EDCs, breastfeeding mothers should take measures to minimize their exposure to these chemicals.

The syndrome of inappropriate antidiuretic hormone secretion (SIADH) is a potential cause of hyponatremia of the central nervous system (CNS). Although SIADH has been reported to be associated with many other central nervous disorders, its association with neuromyelitis optica (NMO) or NMO spectrum disorders are rare. NMO is a demyelinating disorder characterized by optic neuritis and transverse myelitis. Aquaporin-4 (AQP4), which is the target antigen for a NMO autoantibody, is the predominant CNS water channel. However, some NMO patients show seronegative AQP4 antibody results. The spectrum of NMO has been changed, and new findings about the disease have been reported. Here, we report a case of seronegative NMO spectrum disorder associated with SIADH.

OBJECTIVE: This prospective study evaluated the use of continuous sedation using propofol and remifentanil when carpal tunnel release (CTR) was performed under local anesthesia. METHODS: We sedated 60 patients undergoing CTR using local anesthesia with remifentanil at loading and continuous doses of 0.5 microg kg(-1) and 0.05 microg kg(-1)min(-1), respectively, and propofol, using a target controlled infusion (TCI) pump set to a target of 2 microg mL(-1) (group A), or with the same drug doses except that the continuous remifentanil dose was 0.07 microg kg(-1)min(-1) (group B) or 0.1 microg kg-1min-1 (group C). RESULTS: In group B, the levels of pain when local anesthetics were administered (p = 0.001), intraoperative pain (p < 0.001) and anxiety (p = 0.001) were significantly lower than those of group A. Furthermore, the incidence of adverse events, including desaturation (p < 0.001) and vomiting (p = 0.043), was significantly lower in group B than in group C. CONCLUSION: Continuous sedation using an appropriate dose of remifentanil and propofol can be used as safe, efficacious ambulatory anesthesia in cases of CTR under local anesthesia, performed using only 2 mL of local anesthetic, with a high degree of patient satisfaction.

OBJECTIVE: IL-17-producing T cells (Th17 cells) have been identified as a distinct lineage of CD4+ T helper cells in mice. Since this discovery, many efforts have been made to investigate the characteristics and the role of human Th17 cells and the factors involved in their differentiation. This study was undertaken to assess the effects of cytokines and stimulatory conditions on the differentiation of human CD4+ T cells into Th17 cells. METHODS: Peripheral blood CD4+ T cells were isolated from healthy humans and then these cells were cultured with using various stimulatory conditions. The Th17 cells and regulatory T (Treg) cells were detected by flow cytometry (FACs). The related gene expressions of cytokines, transcription factors and chemokine receptors were determined by ELISA and RT-PCR. RESULTS: In the presence of inflammatory cytokines, TNFa and IL-1b, the human CD4+ T cells rapidly produced IL-17 in response to anti-CD3/anti-CD28 stimulation, whereas, with anti-CD3/anti-CD28 stimulation alone, the CD4+ T cells expressed low levels of IL-17. TNFa and IL-1b were also important inducers of IL-22 production. IL-6 and IL-23 up-regulated the RORgammat, CCR4 and CCR6 expressions in the human CD4+ T cells. In response to TGF-b and IL-2, the human CD4+ T cells were rapidly induced to express FoxP3, IL-10 and CCR7, as compared with anti-CD3/anti-CD28 stimulation alone. CONCLUSION: The effect of inflammatory cytokines on the differentiation of human Th17 cells may help us to understand their pathogenic role. Moreover, the differential expression of chemokine receptors and transcription factors of the subsets of CD4+ T cells with the different features of Th17 and Treg, may raise new issues concerning the pathogenesis of autoimmune inflammatory diseases.

BACKGROUND: In this study, we aimed to investigate the relationship between echocardiographic epicardial fat thickness (EFT), neutrophil to lymphocyte ratio (NLR; an important inflammatory marker), and diurnal blood pressure (BP) changes in patients with recently diagnosed essential hypertension. METHODS: A total of 647 patients underwent echocardiography and 24 hours of ambulatory BP monitoring. EFT was measured by echocardiography, while NLR was measured by dividing the neutrophil count by the lymphocyte count. Patients were categorized into three groups according to BP pattern: the normotensive group, the dipper group, and the non-dipper group. RESULTS: The mean EFT was highest in the non-dipper group (non-dipper group, 7.3 ± 3.0 mm; dipper group, 6.1 ± 2.0 mm; control group, 5.6 ± 2.0 mm; p < 0.001). NLR was also highest in the non-dipper group (non-dipper, 2.75 ± 2.81; dipper, 2.01 ± 1.32; control, 1.92 ± 1.11; p < 0.001). EFT was significantly correlated with age (r = 0.160, p < 0.001) and NLR (r = 0.353, p < 0.001). Furthermore, an EFT ≥ 7.0 mm was associated with the non-dipper BP pattern with 51.3% sensitivity and 71.6% specificity [95% confidence interval (CI) = 0.56–0.65, p < 0.001]. In a multivariate analysis, EFT [adjusted odds ratio (OR) = 3.99, 95% CI = 1.22–13.10, p = 0.022] and NLR (OR = 1.34, 95% CI = 1.05–1.71, p = 0.018) were independent parameters that distinguished a non-dipper pattern after adjustment for cardiovascular risk factors. CONCLUSION: EFT and NLR are independently associated with impaired diurnal BP profiles in hypertensive individuals. EFT (as measured by echocardiography) and NLR appear to be helpful in stratifying cardiometabolic risk.

Background:
Giant lip hemangioma is a rare disease that may cause difficulty in preoxygenation and ventilation when using face masks and intubation during general anesthesia induction.Case: A laparoscopic cholecystectomy was planned for a 77-year-old woman. The patient had a giant lower lip hemangioma that was 12 x 5 x 5 cm, which made preoxygenation and ventilation through a face mask impossible and put her at risk of hemangioma rupture. We preoxygenated her through a high-flow nasal cannula (HFNC). Following propofol and succinylcholine administration, we intubated the patient with a video laryngoscope without desaturation, hemangioma rupture, or CO2 retention.
Conclusions
HFNC is a useful tool when difficult intubation is expected in patients who have problems using conventional face masks.

Local anesthetics systemic toxicity (LAST) is a grave complication of regional anesthesia that usually occurs immediately after local anesthetics injection. Here, we report on rare late-onset toxicity cases after supraclavicular brachial plexus blocks. Case: Two patients underwent surgery for radius fractures. We used lidocaine 100 mg and ropivacaine 150 mg for blocking and infused dexmedetomidine for intraoperative sedation. The 63-year-old male patient’s blood pressure dropped to 87/60 mmHg after 3 h 15 min after blocking. Ventricular fibrillation occurred 10 min later. After five defibrillations, electrocardiography showed ventricular tachycardia that was normalized through one cardioversion. The 54-year-old female patient’s heart rate decreased to 35 beats/min 2 h 30 min after blocking. Her vital signs returned to normal after administering atropine, ephedrine, epinephrine, and lipid emulsion. Conclusions: Physicians should remember that LAST may occur long after local anesthetic injection and be aware of factors that may adversely affect the course of LAST.

Background:
Delayed emergence after general anesthesia may significantly affect a patient’s condition. We present the case of a patient who experienced prolonged delayed recovery of consciousness, language, and motor response due to catatonia after eight hours of total elbow arthroplasty under general anesthesia.Case: A 68-year-old woman with neuropsychiatric disorders and Parkinson’s disease did not respond adequately during recovery after more than eight hours of general anesthesia. Following the operation, the patient was semi-comatose and appeared to have nonconvulsive status epilepticus upon awakening from anesthesia. However, subsequent examinations did not reveal any organic causes. The patient was subsequently diagnosed with catatonia, treated, and discharged following gradual improvement.
Conclusions
Although rare, patients taking psychiatric drugs for an extended period may experience delayed emergence after prolonged general anesthesia without identifiable causes. Catatonia should be considered in the differential diagnoses of these patients.
