A Case of Nerve Root Radiofrequency Thermocoagulation for Pain Due to Pleural Metastasis of Lung Cancer Leading to Improvement in the Patient's Quality of Life.

Advances in medicine have made long-term survival of cancer patients possible. Hence, it is now necessary to consider how to approach common symptoms, such as cancer-related pain, in these patients. In this study, we describe a lung cancer patient in whom relief of intractable thoracic pain caused by pleural metastasis was achieved through thoracic radiofrequency thermocoagulation (RF), improving his quality of life (QOL). The patient was a man in his 70s with right upper lobe lung cancer, left 9th -11th rib metastasis, and left thoracic pain associated with parietal pleural metastasis. The patient experienced insomnia and weight loss due to poor appetite caused by opioid analgesics and inadequate pain control. Therefore, RF was performed as interventional treatment, resulting in a decrease in the numerical rating scale score from 10/10 to 2/10, and an improvement in QOL. In cases wherein long-term survival is expected, a long-term treatment plan for chronic cancer-related pain, which has a tendency to become persistent, becomes necessary. RF for the nerve roots might be a viable option for pain caused by pleural metastasis in cancer survivors.

Severe acute cholecystitis successfully treated with endoscopic nasobiliary drainage tube insertion: A case report.

In this report, we present a case of a patient with bile peritonitis caused by gallbladder perforation associated with acute cholecystitis, which required intensive postoperative care. The patient was a woman in her 40s who presented with abdominal pain. Upon examination, she was diagnosed as having acute cholecystitis and bile peritonitis caused by gallbladder perforation. Subsequently, a partial cholecystectomy, omental pack, and drainage were performed. Initially, her bile duct enzyme levels improved; however, they subsequently increased again. An endoscopic nasobiliary drainage tube was inserted, and thereafter, a decrease in inflammatory response and bile duct enzyme levels was observed. During the course of treatment, respiratory failure and renal impairment occurred, necessitating mechanical ventilation management and continuous hemodiafiltration. In patients with severe acute cholecystitis, in addition to treating the underlying condition, it is crucial to perform procedures perioperatively, in anticipation of the development of additional organ dysfunctions postoperatively.

Presumed first episode of nonconvulsive status epilepticus as the cause of postoperative disorder of consciousness following the completion of general anesthesia: A case report.

Key Clinical Message: Disorder of consciousness can lead to irreversible sequelae without proper intervention. Consequently, early diagnosis and treatment are of paramount importance in patients with disorder of consciousness. Abstract: Disorder of consciousness (DOC) has various etiologies. Here, we report a case in which DOC following general anesthesia was suspected as being due to the first episode of nonconvulsive status epilepticus (NCSE). An elderly man in his 80s underwent uneventful tumor resection surgery under general anesthesia for extramammary Paget's disease. After the procedure, he regained consciousness following anesthesia discontinuation and was extubated. Soon after extubation, however, although his respiratory status remained stable, his level of consciousness deteriorated to a Glasgow Coma Scale (GCS) score of E1V1M1. Head computed tomography and magnetic resonance imaging scans indicated no abnormal findings. Subsequently, involuntary movements were noted in his left upper limb. Suspecting an epilepsy episode, diazepam was administered, leading to an improvement in the level of consciousness (GCS: E4V5M6). Based on the improvement in consciousness after diazepam administration, we strongly suspected NCSE.

Successful Perioperative Management of Cochlear Implantation in a Patient With Mitochondrial Encephalopathy, Lactic Acidosis, and Stroke-Like Episodes (MELAS).

Mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes (MELAS) is a type of mitochondrial disease that is characterized by stroke-like seizures. For these patients, serious, unexpected complications have occurred during and following anesthetic exposure. Provision of anesthesia is challenging, including the choice of anesthetic agents. We here report a case of general anesthesia management for a patient with MELAS. A 46-year-old woman was diagnosed with MELAS at the age of 40. She subsequently underwent cochlear implantation for hearing loss. Anesthesia was induced with midazolam and maintained with desflurane. In the present case, anesthesia was maintained with inhalation anesthetics to avoid the development of propofol infusion syndrome. Her intraoperative and postoperative courses were uneventful. The anesthesia management of patients with MELAS can be performed safely with carefully planned anesthesia and close monitoring at each step, including the postoperative period.

Anesthetic management of a morbidly obese patient with endometrial cancer during robot-assisted laparoscopic surgery.

BACKGROUND: The number of robot-assisted surgeries being performed has increased in recent years, even in patients with risk factors, such as obesity, owing to advancements in medical technologies. We here report the anesthetic management of a morbidly obese woman who underwent robot-assisted surgery. CASE PRESENTATION: A 44-year-old woman (height, 165 cm; weight, 147 kg; body mass index, 54 kg/m2) was scheduled to undergo robot-assisted laparoscopic hysterectomy for endometrial cancer. Preoperative weight loss and rehearsal of positioning during induction of anesthesia and surgical procedures greatly contributed to the surgical success. Monitoring of oxygen reserve index in combination with SpO2 was useful for appropriate airway and respiratory management. During anesthesia induction, the ramp position using a special commercially available cushion facilitated manual mask ventilation and tracheal intubation. Lung-protective ventilation using a limited tidal volume with moderate PEEP was applied during the robot-assisted surgical procedure. CONCLUSION: We successfully managed anesthesia without any complications.

Impaired ATP6V0A2 expression contributes to Golgi dispersion and glycosylation changes in senescent cells.

Many genes and signaling pathways have been found to be involved in cellular senescence program. In the present study, we have identified 16 senescence-associated genes by differential proteomic analysis of the normal human diploid fibroblast cell line, TIG-1, and focused on ATP6V0A2. The aim of this study is to clarify the role of ATP6V0A2, the causal gene for ARCL2, a syndrome of abnormal glycosylation and impaired Golgi trafficking, in cellular senescence program. Here we showed that ATP6V0A2 is critical for cellular senescence; impaired expression of ATP6V0A2 disperses the Golgi structure and triggers senescence, suggesting that ATP6V0A2 mediates these processes. FITC-lectin staining and glycoblotting revealed significantly different glycosylation structures in presenescent (young) and senescent (old) TIG-1 cells; reducing ATP6V0A2 expression in young TIG-1 cells yielded structures similar to those in old TIG-1 cells. Our results suggest that senescence-associated impaired expression of ATP6V0A2 triggers changes in Golgi structure and glycosylation in old TIG-1 cells, which demonstrates a role of ATP6V0A2 in cellular senescence program.
