We investigated the effect of KIOM-79, 80% ethanolic extract of herbal prescription isolated from Magnolia officinalis, Pueraria lobate, Glycyrrhiza uralensis, and Euphorbia pekinensis, on streptozotocin-induced diabetes in Sprague-Dawley rats. The rats were treated orally with KIOM-79 (500 mg/kg/day) 1) for 3 days prior to streptozotocin (60 mg/kg, intraperitoneal) injection or 2) for 9 weeks after establishing diabetes model to examine acute and chronic effects on hyperglycemia and biochemical variables, respectively. As a result, KIOM-79 had little effects on hyperglycemic changes in acute model. Sexual comparison, however, showed reduced hyperglycemia in female rats, especially 24 hours after streptozotocin injection with or without KIOM-79 pretreatment. In chronic model, streptozotocin-induced hyperglycemia was well established, but KIOM-79 treatment showed no statistically significant effects on all variables. Thus, based on our findings KIOM-79 might have little effects on streptozotocin-induced insulin-dependent diabetes although it has been known to have hypoglycemic and antidiabetic effects on non-insulin-dependent diabetes models.

This case report describes a case of isolated (not associated with other anomalies) lower vaginal hypoplasia complicated by megalourethra (urethral dilatation) due to frequent urethral sexual intercourse in a regularly menstruating (hypomenorrheic) woman. The patient was a 24-year-old woman who underwent transperineal ultrasonography as well as magnetic resonance imaging followed by sequential cystoscopic and vaginoscopic examinations. Finally, a pull-through procedure was used to create a new vagina. The main outcome measure was patent vagina formation. The procedure successfully corrected isolated lower vaginal hypoplasia. The postoperative course was smooth, with the restoration of regular intercourse in the correct location. It was concluded that all gynecologists should have increased awareness of rare female genital anomalies to avoid serious sequelae, particularly in newly married patients.

Transient receptor potential ankyrin 1 (TRPA1) receptors are major polymodal nociceptors that generate primary pain responses in the peripheral nerve endings of the dorsal root ganglion neurons. Recently, we reported that the activation of TRPA1 receptors by reactive oxygen species (ROS) signaling, which is triggered by Ca2+ influx through T-type Ca2+ channels, contributes to prolonged pain responses induced by jellyfish toxin. In this review, we focus on the characteristics of the TRPA1 receptor involved in intracellular signaling as a secondary pain modulator. Unlike other transient receptor potential receptors, TRPA1 receptors can induce membrane depolarization by ROS without exogenous stimuli in peripheral and central sensory neurons. Therefore, it is important to identify the functional characteristics of TRPA1 receptors to understand pain modulation under several pathogenic conditions such as neuropathic pain syndromes and autoimmune diseases, which are mediated by oxidative signaling to cause chronic pain in the sensory system.

Objective: To estimate the efficacy of sequential treatment of bladder endometriosis (BE) of the vesicoureteric junction using transurethral resection (TUR) and hormonal therapy. Design: Case report. Setting: Private multispecialty hospital. Patient: A multiparous woman presented with perimenstrual lower urinary tract symptoms, cyclic chronic pelvic pain, and left loin pain. Intervention[s]: Ultrasonography revealed marked left renal dilatation. Computed tomography confirmed the presence of a bladder mass. A diagnostic cystoscopy revealed compression of the left vesicoureteral junction. Complete TUR BE with release of chocolate material during resection, followed by ureteric double J stent insertion for 3 months, was performed. Histopathology confirmed the diagnosis of BE, followed by adjuvant hormonal therapy (dienogest) for 3 months. Followup for about 2 years revealed complete relief of the symptoms without any recurrence. Main Outcome Measure[s]. Success and recurrence rates of sequential TUR and hormonal therapy of BE of the vesicoureteric junction. Result[s]. TUR BE followed by adjuvant hormonal therapy was very effective in eradicating BE of the vesicoureteric junction in a safe manner without recurrence on follow-up for 2 years. Conclusion[s]. BE of the vesicoureteric junction can be properly treated by sequential TUR and hormonal therapy without recurrence over a 2-year follow-up.

Streptococcus suis (S. suis) is an emerging zoonotic pathogen that causes bacterial meningitis in humans. S. suis is an encapsulated grampositive facultative anaerobic bacterium and is an important pathogen in pigs. This infectious disease usually manifests in humans as meningitis, endocarditis, septicemia, and arthritis. Most cases originate in Southeast Asia, and human S. suis infections are often reported in countries with a high density of pigs. Meningitis is a common clinical manifestation of S. suis infection. Moreover, hearing loss is a common complication that can be bilateral, profound, and/or permanent. This report presents two cases of bacterial meningitis and hearing loss caused by S. suis in patients without a history of direct exposure to pigs in an intensive pork industry region.

Interest in the metaverse is increasing as learners participate in learning with presence, improving learning motivation, and interaction. Currently, the use of metaverse in medical education remains in a test-phase of introduction within some companies, while some medical school professors are beginning to utilize it. Therefore, it is difficult to ascertain whether the metaverse has educational potential when used in medical education. This exploratory study investigates the possibility of the educational use of the metaverse. Both the educational usefulness and the examples of its educational usage in domestic and foreign medical schools are explored. As the metaverse is expected to be introduced and utilized more actively in the future, some of its advantages and limitations in medical education have been identified. In light of the vast potential of the metaverse in medical education, the method of educating and preparing medical students should be developed by preparing a new educational foundation.

The demand for total knee arthroplasty (TKA) is rapidly increasing worldwide. The most common indication for TKA is osteoarthritis (OA); however, some patients with rheumatoid arthritis (RA) also undergo TKA. This study aimed to investigate the effects of RA on TKA. Our findings revealed that patients with RA underwent TKA at a younger age than did patients with OA. However, contrary to the findings of pre-21st century studies, the average age of TKA among patients with RA was not significantly different from that of patients with OA. Additionally, patients with RA had a 1.5-fold higher risk of undergoing TKA. Although not statistically significant, patients with RA had a higher revision TKA rate, a shorter time until revision TKA, and underwent more revision TKAs due to infections than did patients with OA. An analysis of factors that affect revision TKA revealed that the risk of revision increased if the erythrocyte sedimentation rate and C-reactive protein levels were increased at the time of TKA. This study showed that patients with RA have a slightly higher risk of undergoing TKA than did patients with OA. Furthermore, the presence of inflammation at the time of TKA increases the risk of revision; therefore, inflammation should be adequately controlled before performing TKA.

This report presents the case of 75-year-old men with spindle cell neoplasm. The patient underwent percutaneous nephrolithotomy and transurethral resection of the prostate (TURP) for renal stones and benign prostatic hyperplasia. One month postoperatively, the patient was able to void without any difficulty. Five months later, the patient experienced difficulty voiding and presented to the emergency room with severe pelvic pain. Computed tomography (CT) showed regrowth of the prostate mass into the posterior bladder and penile root. The prostate-specific antigen level remained constant at 1.14 ng/mL during the pre-and postoperative periods. Five months before the TURP operation, the patient’s CT scan showed a soft and mildly enlarged prostate with no protrusion into the bladder. Biopsy of the prostate, however, showed a protruding mass, indicative of a spindle cell neoplasm. The patient was subsequently treated with the chemotherapeutic drug adriamycin. Unfortunately, treatment was unsuccessful, and the patient died 18 months later.
Serous tubal intraepithelial carcinoma detected during benign gynecologic surgery: a case report
Eun Seo Shin,Sung Yob Kim 제주대학교 의과학연구소 2023 The Journal of Medicine and Life Science Vol.20 No.1
High-grade serous carcinoma (HGSC) is the most common type of pelvic cancer among women. Serous tubal intraepithelial carcinoma (STIC) is a precursor lesion of HGSC. Herein, we report a rare occurrence of STIC in patients undergoing surgery for benign indications without a family history of ovarian cancer. A 77-year-old woman underwent total laparoscopic hysterectomy and bilateral salpingo-oophorectomy for uterine prolapse. Pathological examination revealed bilateral STIC without ovarian abnormalities, and no other abnormal findings were noted. Another patient, a 49-year-old woman, underwent laparoscopic total hysterectomy and bilateral salpingectomy for uterine fibroids. STIC lesions were observed in both fallopian tubes. Subsequently, a staging was performed. No additional lesions were found, and the patient was followedup through imaging and blood tests. As reports of STIC lesions are rare, data on their clinical outcomes and management strategies are limited. In this report, we present cases of incidental STIC in benign surgery and discuss its proper interpretation and management. Through the early detection of STIC lesions, patients with risk factors can be identified in advance, which will allow prevention and early detection of ovarian cancer. Opportunistic salpingectomy was also actively discussed in this regard.
