Purpose: Diabetic foot ulcers and gangrene are major complications of diabetes, often accompanied by peripheral vascular occlusion.Revascularization is performed to restore blood flow and reduce complications such as amputation surgery. Nevertheless, reocclusion, a frequently reported complication after revascularization, often necessitates further lower limb amputations to facilitate rehabilitation and ambulation. This study examined the factors influencing the performance of secondary revascularization procedures in patients with diabetic foot gangrene who even underwent transtibial amputation (TTA) following revascularization. Materials and Methods: A retrospective study was conducted on 36 patients with diabetic foot gangrene who underwent TTA after revascularization from March 2005 to March 2022. The factors influencing restenosis were classified into three categories: revascularization factors, preoperative factors, and intraoperative factors. The revascularization factors were categorized based on whether percutaneous transluminal angioplasty (PTA) or bypass surgery had been performed. Preoperative factors included the patient’s age, gender, body mass index (BMI), hypertension, and other relevant factors. Intraoperative factors included surgery duration, blood loss, and transfusion. The study examined the factors influencing secondary revascularization in these three categories. Results: Among the 36 patients in the study, 27.8% (11 patients) underwent secondary revascularization procedures. There was no significant correlation between the performance of secondary revascularization and the type of revascularization procedure, whether PTA or bypass surgery (p>0.05). Similarly, no significant differences were observed in preoperative factors (including age, BMI, smoking status, HbA1c, and underlying diseases) and intraoperative factors (surgery duration, blood loss, and transfusion). On the other hand, regarding gender, all patients who underwent revascularization procedures were male, indicating a statistically significant result (p=0.039). Conclusion This study suggests that while most clinical variables showed no association with reocclusion, the fact that all patients who underwent secondary revascularization procedures were male indicates that gender may be a significant predictive factor of revascularization.

The term electrosurgery refers to the passage of high-frequency alternating electrical current through the tissue, to achieve a specific surgical effect. It is used in everyday dermatologic practice for various purposes, including tissue dissection, bleeding control, and the removal of common skin lesions such as viral warts, melanocytic nevi, and cherry angiomas. Considering the nature of the device, adverse effects including skin burn and scarring can occur at any stage of the procedure. Therefore, it is essential that electrosurgery be performed by skilled and well-trained physicians. In this paper, we introduce a brief history of electrosurgery and present its categories and their clinical uses. In addition, the possible adverse effects and safety measures of electrosurgery are addressed.

BACKGROUND: This randomized, controlled study was designed to compare the effects of recruitment maneuvers (RMs) with a 15 cmH₂O positive end-expiratory pressure (PEEP) on the systemic oxygenation and lung compliance of patients with healthy lungs following robot-assisted laparoscopic prostatectomy (RALP). METHODS: Sixty patients undergoing a RALP with an intraoperative 15 cmH₂O PEEP were randomly allocated to an RM or a Control group. The patients in the RM group received a single RM through the application of a continuous positive airway pressure of 40 cmH₂O for 40 s 15 min after being placed in the Trendelenburg position. The arterial oxygen tension (PaO₂, primary endpoint) and the pulmonary dynamic and static compliances (secondary endpoints) were measured 10 min after the anesthetic induction (T1), 10 min after establishment of the pneumoperitoneum (T2), 10 min after establishment of the Trendelenburg position (T3), 10 min after the RM (T4), 60 min after the RM (T5), and 10 min after deflation of the pneumoperitoneum in the supine position (T6). RESULTS: The intergroup comparisons of the PaO₂ showed significantly higher values in the RM group than in the Control group at T4 and T5 (193 ± 35 mmHg vs. 219 ± 33 mmHg, P = 0.015, 188 ± 41 mmHg vs. 214 ± 42 mmHg, P = 0.005, respectively). However, the PaO₂ at T6 was similar in the two groups (211 ± 39 mmHg vs. 224 ± 41 mmHg, P = 0.442). Moreover, there were no statistical differences between the groups in the dynamic and static compliances of the lungs at any time point. CONCLUSIONS: The arterial oxygenation of the patients with a healthy lung function who had undergone a RALP with intraoperative 15 cmH₂O PEEP was improved by a single RM. However, this benefit did not last long, and it did not lead to an amelioration of the lung mechanics.

Herpes zoster oticus or Ramsay Hunt syndrome occurs in about one percent of all cases of herpes zoster and represents 12 percent of all facial palsies. The typical clinical presentation includes otalgia, facial palsy, herpetic lesions of the auricle and external auditory canal, but is frequently accompanied with sensorineural hearing loss, vertigo and tinnitus. Rarely, it may be associated with the involvement of V, VI, IX, X, XI and XII cranial nerves, aseptic meningitis, and the syndrome of inappropriate secretion of antidiuretic hormone (SIADH). With a review of literature, we report two cases. The first case is a 64-year-old male with Ramsay Hunt syndrome complicated with cranial nerve VIII palsy and aseptic meningitis. The second case is a 30-year-old female with Ramsay Hunt syndrome complicated with the cranial nerve III, IV, V, VI and VIII palsies and aseptic meningitis.

BACKGROUND: Next-generation sequencing is increasingly used for taxonomic identification of pathogenic bacterial isolates. We evaluated the performance of a newly introduced whole genome-based bacterial identification system, TrueBac ID (ChunLab Inc., Seoul, Korea), using clinical isolates that were not identified by three matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) systems and 16S rRNA gene sequencing. METHODS: Thirty-six bacterial isolates were selected from a university-affiliated hospital and a commercial clinical laboratory. Species was identified by three MALDI-TOF MS systems: Bruker Biotyper MS (Bruker Daltonics, Billerica, MA, USA), VITEK MS (bioMérieux, Marcy l'Étoile, France), and ASTA MicroIDSys (ASTA Inc., Suwon, Korea). Whole genome sequencing was conducted using the Illumina MiSeq system (Illumina, San Diego, CA, USA), and genome-based identification was performed using the TrueBac ID cloud system (www.truebacid.com). RESULTS: TrueBac ID assigned 94% (34/36) of the isolates to known (N=25) or novel (N=4) species, genomospecies (N=3), or species group (N=2). The remaining two were identified at the genus level. CONCLUSIONS: TrueBac ID successfully identified the majority of isolates that MALDI-TOF MS failed to identify. Genome-based identification can be a useful tool in clinical laboratories, with its superior accuracy and database-driven operations.
