Human reflexes are simple motor responses that are automatically elicited by various sensory inputs. These reflexes can provide valuable insights into the functioning of the nervous system, particularly the brainstem and spinal cord. Reflexes involving the brainstem, such as the blink reflex, laryngeal adductor reflex, trigeminal hypoglossal reflex, and masseter H reflex, offer immediate information about the cranial-nerve functionality and the overall state of the brainstem. Similarly, spinal reflexes such as the H reflex of the soleus muscle, posterior root muscle reflexes, and sacral reflexes provide crucial information about the functionality of the spinal cord and peripheral nerves. One of the critical benefits of reflex monitoring is that it can provide continuous feedback without disrupting the surgical process due to no movement being induced in the surgical field. These reflexes can be monitored in real time during surgical procedures to assess the integrity of the nervous system and detect potential neurological damage.It is particularly noteworthy that the reflexes provide motor and sensory information on the functional integrity of nerve fibers and nuclei. This article describes the current techniques used for monitoring various human reflexes and their clinical significance in surgery. We also address important methodological considerations and their impact on surgical safety and patient outcomes. Utilizing these methodologies has the potential to advance or even revolutionize the field of intraoperative continuous monitoring, ultimately leading to improved surgical outcomes and enhanced patient care.

Background:
Hand hygiene is considered the simplest and most cost-effective method of infection prevention. Regular observation and feedback on hand hygiene compliance are key strategies for its enhancement. This study evaluated the effectiveness of hand hygiene surveillance, including direct observation and feedback, by comprehensively analyzing the reported hand hygiene compliance within the Korean National Healthcare-Associated Infections Surveillance System from 2019 to 2022.
Methods:
Participating medical institutions included general hospitals and hospitals with infection control departments that consented to participate. Hand hygiene surveillance was conducted using direct observation. Collected data, including healthcare workers, clinical areas, hand hygiene moments, and hand hygiene compliance, were recorded to calculate hand hygiene compliance rates. Additionally, the volume of alcohol-based hand sanitizers used per patient per day was investigated as an indirect indicator of hand hygiene compliance. The study was conducted from July 2019 to December 2022.
Results:
Hand hygiene compliance increased from 87.2% in Q3 2019 to 89.9% in 2022. Nurses and medical technologists showed the highest compliance rates, whereas doctors showed the lowest compliance rates. Intensive care units excelled in compliance, whereas emergency de partments lagged. Compliance was highest after patient contact and lowest when the patient’s surroundings were touched. Larger hospitals consumed more alcohol-based hand sanitizers than smaller hospitals did.
Conclusion
This study confirmed an improvement in hand hygiene compliance through sustained surveillance, indicating its contribution not only to preventing infection transfer within healthcare facilities but also to fostering a culture of hand hygiene in the country.

Purpose:
Targeted next-generation sequencing (NGS) panels for solid tumors have been useful in clinical framework for accurate tumor diagnosis and identifying essential molecular aberrations. However, most cancer panels have been designed to address a wide spectrum of pan-cancer models, lacking integral prognostic markers that are highly specific to gliomas.
Materials and Methods:
To address such challenges, we have developed a glioma-specific NGS panel, termed “GliomaSCAN,” that is capable of capturing single nucleotide variations and insertion/deletion, copy number variation, and selected promoter mutations and structural variations that cover a subset of intron regions in 232 essential glioma-associated genes. We confirmed clinical concordance rate using pairwise comparison of the identified variants from whole exome sequencing (WES), immunohistochemical analysis, and fluorescence in situ hybridization.
Results:
Our panel demonstrated high sensitivity in detecting potential genomic variants that were present in the standard materials. To ensure the accuracy of our targeted sequencing panel, we compared our targeted panel to WES. The comparison results demonstrated a high correlation. Furthermore, we evaluated clinical utility of our panel in 46 glioma patients to assess the detection capacity of potential actionable mutations. Thirty-two patients harbored at least one recurrent somatic mutation in clinically actionable gene.
Conclusion
We have established a glioma-specific cancer panel. GliomaSCAN highly excelled in capturing somatic variations in terms of both sensitivity and specificity and provided potential clinical implication in facilitating genome-based clinical trials. Our results could provide conceptual advance towards improving the response of genomically guided molecularly targeted therapy in glioma patients.

Primary hyperparathyroidism (PHPT) is imbalance of calcium, phosphate, and bone metabolism attributed to an increased secretion of parathyroid hormone (PTH). Although PHPT is mainly associated with musculoskeletal and kidney dysfunction, variable symptoms can be presented in the elderly patients. A 75-year-old man presented with rapidly progressive dementia (RPD). Through etiological work-up of hypercalcemia and increased PTH, parathyroid adenoma was found. Subtotal parathyroidectomy resulted in recovery of cognitive impairment. Primary hyperparathyroidism should be considered in a differential diagnosis of RPD.

9.Hyperinsulinemic Hypoglycemia After Roux-en-Y Gastric Bypass.
Journal of Korean Diabetes 2013;14(2):83-86
Bariatric surgery is one of the most efficient ways to achieve weight loss and reduce the complications associated with obesity. Severe hypoglycemia can occur after bariatric surgery, though it is rare. Hypoglycemic episodes have so far been poorly studied and the pathophysiology of hypoglycemia has not yet been demonstrated. Currently, there are two different hypotheses; the first is that hypoglycemic episodes are secondary to hyperinsulinemia and result from beta-cell hyperplasia or hyperfunction. The second is that the primary problem is beta-cell failure, which allows glucose concentrations to reach high values. The few therapeutic options that have been validated are also discussed in this study.

Cutaneous mucinous eccrine carcinoma is a rare malignant tumor that is presumably of an eccrine gland origin. We observed a 53-year-old man with an erythematous nodule on his left infraorbital area. A large mucinous pool and characteristic tumor cells were shown on H&E stain, and further specific immunohistochemical stains confirmed the diagnosis. We report here on a case of mucinous eccrine carcinoma and we review the relevant literature.
