Bilateral video-assisted thoracic surgery for esophageal cancer with left inferior pulmonary vein invasion following chemoradiation therapy.

BACKGROUND: The surgical strategy for thoracic esophageal cancer that invades the lungs is controversial. In particular, invasion of the pulmonary vein is often regarded unresectable. We successfully applied bilateral video-assisted thoracic surgery (VATS) in esophagectomy for esophageal cancer with left inferior pulmonary vein invasion following induction chemoradiotherapy (CRT), with a favorable response. CASE PRESENTATION: A 64-year-old woman was diagnosed with squamous cell carcinoma of the lower third of the esophagus. Computed tomography (CT) revealed that the tumor was suspected to be invading the main trunk of the left lower pulmonary vein and left lower lung. We initiated induction CRT comprising 5-fluorouracil, cisplatin, and concurrent radiotherapy at 50.4 Gy/28Fr. CT revealed shrinkage of the tumor, and the main trunk of the left inferior pulmonary vein was released from the tumor invasion. We considered the tumor to be completely resectable. VATS esophagectomy is usually performed using a right-sided approach. However, the right-sided approach is inappropriate for evaluating tumors around the left inferior pulmonary vein. We started with left-sided VATS to determine tumor resectability and dissected between the esophagus and the main trunk of the left inferior pulmonary vein. We only needed to perform partial resection of the left lower lobe. We then performed a right-sided VATS esophagectomy and lymphadenectomy with partial en bloc resection of the left lower lobe. Following this, we performed hand-assisted laparoscopic proximal gastrectomy and reconstruction using the gastric remnant. The postoperative course was uneventful. The patient was discharged on postoperative day 14. Histopathological examination of the surgical specimen revealed a complete pathological response without any remnant tumor or lymph node metastasis. There were no signs of recurrence or metastasis at the 1-year follow-up. CONCLUSIONS: Curative resection for thoracic esophageal cancer that invades the pulmonary vein could be possible via the bilateral VATS approach following induction CRT with a favorable response.

PYloroplasty versus No Intervention in GAstric REmnant REconstruction after Oesophagectomy: study protocol for the PYNI-GAREREO phase III randomized controlled trial.

BACKGROUND: After esophagectomy for esophageal and esophagogastric cancer, more than half of patients have lost > 10% of their body weight at 12 months. In most cases, the gastric remnant is used for reconstruction after esophagectomy. One of the most serious nutritional complications of this technique is delayed gastric emptying caused by gastric remnant mobilization and denervation of the vagus nerve. The aim of the PYloroplasty versus No Intervention in GAstric REmnant REconstruction after Oesophagectomy (PYNI-GAREREO) trial is to analyze the clinical outcome of modified Horsley pyloroplasty (mH-P) as a method of preventing delayed gastric emptying. METHODS: The PYNI-GAREREO trial is designed as an open randomized, single-center superiority trial. Patients will be randomly allocated to undergo gastric remnant reconstruction with mH-P (intervention group) or no intervention (control group) in parallel groups. All patients with esophageal cancer or esophagogastric cancer planning to undergo curative minimally invasive esophagectomy will be considered for inclusion. A total of 140 patients will be included in the study and randomized between the groups in a 1:1 ratio. The primary outcome is the body weight change at 6 months postoperatively, and the secondary outcomes are the nutritional status, postoperative complications, functional outcome, and quality of life until 1 year postoperatively. DISCUSSION: We hypothesize that mH-P after minimally invasive esophagectomy more effectively maintains patients' nutritional status than no pyloroplasty.

Spontaneous retroperitoneal hematoma: a case report.

BACKGROUND: Spontaneous retroperitoneal hematoma is defined as bleeding in the retroperitoneal space without any triggers such as trauma, invasive procedures, and abdominal aortic aneurysm. CASE PRESENTATION: A 48-year-old Japanese man who experienced sudden abdominal pain, severe hypotension, and decreased hemoglobin was diagnosed with spontaneous retroperitoneal hematoma. Contrast-enhanced computed tomography revealed massive left retroperitoneal hematoma; however, neither extravasation nor causative aneurysm was noted. Through conservative management with close monitoring, he was treated and discharged on the tenth hospital day without any morbidity. CONCLUSIONS: Spontaneous retroperitoneal hematoma treatment comprises conservative management, transcatheter arterial embolization, and surgical intervention. The mortality rate of spontaneous retroperitoneal hematoma is so high that the optimal treatment timing needs to be carefully judged on the basis of detailed evaluation, and management algorithm with clear criteria.

Multiple esophageal hematomas with oozing observed and successfully treated after transcatheter mitral valve edge-to-edge repair procedure.

Although previously reported as relatively rare, esophageal hematoma can likely develop in patients on anticoagulants or those with underlying hemorrhagic disorders. From April 2018 to December 2018, among 36 patients who received transcatheter mitral valve edge-to-edge repair (TMVr) at our hospital, seven (19.4%), who were suspected of having digestive tract hemorrhage evidenced by blood stains on a probe extracted after transesophageal echocardiography, underwent esophagogastroduodenoscopy. Esophageal hematomas were noted in all patients, and endoscopic hemostasis was performed in two cases. Depending on their form, hematomas were noted on the submucosa and the epithelium of the shallow esophageal layer. Esophageal hematomas caused by transesophageal echocardiography for TMVr are not rare, and clinicians should be aware of it.

Carbon dioxide embolism during transanal total mesorectal excision: A hint of prevention from a case report.

Transanal total mesorectal excision is a relatively new approach for treating lower rectal cancer. Carbon dioxide embolism is a critical complication of this procedure. We report the case of a 69-year-old man with lower rectal cancer who underwent transanal total mesorectal excision followed by laparoscopic low anterior resection. He had a sudden intraoperative carbon dioxide embolism during the transanal mesorectal excision. During the ventral dissection of the rectum, end-tidal carbon dioxide and blood oxygen saturation suddenly decreased. We stopped the insufflation of carbon dioxide and suspended the procedure. There was no circulatory collapse, and the vital signs gradually recovered; therefore, we resumed the surgery approximately 30 minutes later and completed it without additional complications. Upon reviewing the video, we found a small injured vein that would aspirate carbon dioxide. These findings suggested that careful hemostasis is essential to prevent carbon dioxide embolus during transanal total mesorectal excision.

Gastric remnant reconstruction with left gastroepiploic artery supercharge after esophagectomy in a patient with an occluded right gastroepiploic artery: A technical and case report.

INTRODUCTION: Gastric remnant reconstruction is commonly used for esophagectomy reconstruction. However, standard reconstruction cannot be performed in some patients with a specific medical history. We report a case of esophagectomy and gastric remnant reconstruction with left gastroepiploic artery (LGEA) supercharge to treat esophageal cancer in a patient in whom the right gastroepiploic artery (RGEA) had previously been occluded. PRESENTATION OF CASE: A 65-year-old man underwent endoscopic submucosal dissection for thoracic esophageal squamous cell carcinoma. He was diagnosed with pathological T1b cancer with lymphatic invasion and a positive horizontal margin, and needed curative resection. He had previously undergone RGEA embolization to treat a pseudoaneurysm caused by chronic pancreatitis. We successfully performed esophagectomy and gastric remnant reconstruction with preoperative left gastric artery embolization and intraoperative LGEA supercharge. DISCUSSION: An absent RGEA blood supply is not always a contraindication for gastric remnant reconstruction when the collateral blood flows are well developed and supercharge can maintain the blood supply to the gastric remnant. CONCLUSIONS: Gastric remnant reconstruction with preoperative selective arterial embolization and intraoperative supercharge represents one of the options for high-risk patients with an altered gastric blood supply.

Prediction of Apnea Testing Duration to Ensure Safety During Brain Death Assessment.

BACKGROUND: Apnea testing is the last step of brain death assessment. This study aimed to determine whether apnea testing is safer when performed over a shorter duration. METHODS: The medical records of 200 brain-dead donors were retrospectively evaluated. All the records were anonymously registered in the Japanese Ministry of Health, Labor, and Welfare from 1999 to 2012. The rate of [Formula: see text] increase was analyzed to calculate the duration required for apnea testing. RESULTS: At baseline, body temperature and [Formula: see text] significantly affected the increase rate of [Formula: see text]. At baseline, the apnea testing durations were 4.7 min with normal body temperature and higher [Formula: see text] ([Formula: see text] 40-60 mm Hg, body temperature 36.5°C, [Formula: see text] 400 mm Hg); further, it was 3.0 min with higher body temperature and lower [Formula: see text] at baseline ([Formula: see text] 40-60 mm Hg, body temperature 38.0°C, [Formula: see text] 100 mm Hg). CONCLUSIONS: The specific duration of apnea testing during brain death assessment may be predicted by measuring the increase rate of [Formula: see text].

Comparison of various risk scores for the prognosis of hemorrhagic upper gastrointestinal mucosal disorder.

BACKGROUND: Various risk scores have been proposed that are useful for the management of upper gastrointestinal bleeding (UGIB), which is an important disease in emergency medicine. Few studies have examined the usefulness of Charlson Comorbidity index (CCI) in this disease, which evaluates the patient's general condition by scoring the patient's underlying disease. There have been no studies investigating the efficacy of CCI compared to other risk scores in the management of UGIB requiring endoscopic hemostasis. METHODS: In addition to the Glasgow-Blatchford score, AIMS65 score, and Rockall score, we investigated the efficacy of the outcome prediction obtained by the original CCI and the updated CCI, scored only with respect to the underlying disease. We also examined the cutoff value when using the risk score. This retrospective study included 265 patients with hemorrhagic upper gastrointestinal mucosal lesions who underwent emergency endoscopic hemostasis during a 6-year period between 2011 and 2016 in our hospital. RESULTS: The updated CCI and AIMS65 score correlated with prognosis in multivariate analysis (p = 0.002 and p = 0.003, respectively). In clinical practice, the prognosis might be worse if both updated CCI and AIMS65 score were 3 point or more. CONCLUSION: In addition to the AIMS65 score, the updated CCI can be a useful tool for managing upper gastrointestinal mucosal disorder bleeding that requires endoscopic hemostasis.

Establishment of a novel method for the identification of fertilization defective mutants in Arabidopsis thaliana.

Plant reproduction is an extremely important phenomenon, as it is strongly associated with plant genetics and early development. Additionally, foundations of the reproductive system have direct implications on plant breeding and agriculture. Investigation of the functions of male and female gametophytes is critical since their fusion is required for seed formation. Although a large number of mutants have been generated to understand the functions of male and female gametophytes, only a small number of genes required for plant fertilization have been identified to date. This is because the screening method used previously required the dissection of siliques, and fertilization-specific mutants exhibiting semi-fertility (or ∼50% fertility) were difficult to identify. Here, we report a new efficient screening method for the identification of fertilization defective mutants in Arabidopsis thaliana using vanillin staining. This method is based on the pollen tube-dependent ovule enlargement morphology (POEM) phenomenon, which generates a partial seed coat within the ovule without fertilization. Using this method, we successfully identified 23 putative fertilization defective mutants in Arabidopsis.

Pathological complete response of locally advanced colon cancer after preoperative radiotherapy: a case report and narrative review of the literature.

BACKGROUND: The oncological effectiveness of preoperative radiotherapy for locally advanced colon cancer is unclear. We report a case of pathological complete response in a patient with locally advanced ascending colon cancer after preoperative radiotherapy following failure of chemotherapy. CASE PRESENTATION: A 65-year-old Japanese woman presented with malaise and hematochezia. A computed tomography (CT) revealed a tumor in the ascending colon which seemed to infiltrate the adjacent structures. She was diagnosed with locally advanced ascending colon cancer stages T4b, N2a, M0, and IIIC. We selected modified FOLFOX6 with panitumumab as neoadjuvant chemotherapy. However, we discontinued the chemotherapy after the 8th cycle because of disease progression and severe adverse effects. The patient then underwent radiotherapy of 60 Gy in 30 fractions, resulting in significant tumor size reduction. One month after the radiotherapy, we performed a right hemicolectomy with multivisceral resection without complications. Histopathologically, we found no residual cancer cells in the resected specimen. The patient remains alive and has not required additional therapies for 24 months, as there are no signs of recurrence. CONCLUSIONS: The present case suggests that preoperative radiotherapy might be an effective treatment options for locally advanced colon cancer.

Pupil diameter for confirmation of brain death in adult organ donors in Japan.

Aim: The criteria for brain death in Japan include a bilateral pupil diameter of ≥4 mm. We evaluated the appropriateness of a 4-mm pupil diameter in adult brain-dead donors in Japan. Methods: We retrospectively reviewed the records of 148 consecutive adult brain-dead donors with an average age of 46 years. All records were anonymously registered to the Japanese Ministry of Health, Labour and Welfare (the Japanese Ministry of Health and Welfare before 2001) from the various designated emergency institutes that performed organ donation under brain death from 1999 to 2012 in Japan. Results: All donors had a Glasgow Coma Scale score of 3, absence of all seven brain stem reflexes, an isoelectric electroencephalogram for >30 min, and apnea as tested by the standard method. All of these examinations were repeated approximately 6 h later for confirmation. The pupil diameter (average ± standard deviation) was 6.1 ± 1.1 mm at the first assessment and 6.4 ± 1.1 mm approximately 6 h later. The 95% probability distribution as calculated by statistical analysis was 3.93-8.30 mm in the left eye and 3.88-8.28 mm in the right eye in the first assessment, and 4.25-8.58 mm in the left eye and 4.32-8.43 mm in the right eye approximately 6 h later. Conclusion: Despite the various original causes of brain death, we conclude that a pupil diameter of ≥4 mm is a reasonable criterion for brain death in adults.

Aerosolized tobramycin for Pseudomonas aeruginosa ventilator-associated pneumonia in patients with acute respiratory distress syndrome.

BACKGROUND: Ventilator-associated pneumonia (VAP) due to Pseudomonas aeruginosa has a high mortality and recurrence rate, especially in patients with acute respiratory distress syndrome (ARDS). Therefore, new therapeutic strategies against severe pneumonia are needed. This study evaluated the efficacy of aerosolized tobramycin for P. aeruginosa VAP in ARDS patients. METHODS: A retrospective analysis was performed on patients who developed VAP caused by P. aeruginosa during the course of ARDS at the intensive care unit (ICU) of Kumamoto University Hospital. Aerosolized tobramycin inhalation solution (TIS) 240 mg was administered daily for 14 days in addition to systemic antibiotics. RESULTS: A total of 44 patients (TIS group, n = 22; control group, n = 22) were included in the analysis. No significant differences were found between the two groups in terms of clinical characteristics, including acute physiology and chronic health evaluation II score upon ICU admission. The TIS group had significantly lower recurrence of P. aeruginosa VAP (22.7% vs. 52.4%, P = 0.04) and ICU mortality (22.7% vs. 63.6%, P < 0.01) than the control group. Bacterial concentration in tracheal aspirate (mean log 10 cfu/mL ± SD on days 2-5: 1.2 ± 1.3 vs. 5.0 ± 2.3, P < 0.01) decreased more rapidly and markedly in the TIS group compared with the control group. CONCLUSION: Aerosolized tobramycin was an effective therapeutic strategy for P. aeruginosa VAP patients with ARDS.

Emergency room thoracotomy for acute traumatic cardiac tamponade caused by a blunt cardiac injury: A case report.

INTRODUCTION: Traumatic blunt cardiac injuries have a high mortality rate, and prompt diagnosis and treatment can be lifesaving in cardiac tamponade. PRESENTATION OF CASE: A 62-year-old man was transferred to the emergency department after a motor vehicle accident. He was hemodynamically unstable. A focused assessment with sonography in trauma (FAST) showed pericardial fluid with right ventricular collapse consistent with cardiac tamponade in the subxiphoid view. He collapsed despite a subxiphoid pericardiotomy. Owing to the ongoing hemodynamic instability, we performed a left anterolateral thoracotomy. Direct incision of the pericardium showed blood and clots within the pericardial space, indicating hemopericardium. The heart stroke and hemodynamic status recovered on removing the clot. DISCUSSION: Although the physical findings of cardiac tamponade are not always apparent in life-threatening acute cardiac tamponade after blunt trauma, FAST is a reliable tool for diagnosing and following cardiac tamponade. A median sternotomy is a standard approach for evaluating cardiac injury in hemodynamically stable patients with or without cardiopulmonary bypass. However, a left anterior thoracotomy was the fastest, simplest life-saving procedure considering the need for open-chest cardiac massage given our patient's life-threatening condition. CONCLUSION: A prompt diagnosis using FAST and treatment can be lifesaving in traumatic acute cardiac tamponade. A pericardiotomy via a thoracotomy is mandatory for lifesaving cardiac decompression in acute traumatic cardiac tamponade in cases of ineffective drainage due to clot formation within the pericardial space.

Immunohistochemical Analysis of WT1 Antigen Expression in Various Solid Cancer Cells.

For a peptide-pulsed dendritic cell (DC) vaccine to work effectively in cancer treatment, it is significant that the target protein is expressed in cancer cells. Wilms' tumor 1 (WT1) has been identified as a molecular target for immune cell therapy of cancer. We evaluated the protein expression levels of WT1 in various solid tumors, as well as mucin 1 (MUC1) or major histocompatibility complex (MHC) class l molecules. Seven hundred and thirty-eight patients whose tissue samples were examined by immunohistochemical analysis agreed to undergo DC vaccine therapy. The positive staining of WT1 in tumor cells was observed in 25.3% of patients, with only 8.5% of them showing moderate to strong expression; moreover, WT1 tended to localize in the nucleus and cytoplasm. A positive staining of tumor cells by an anti-MHC class l monoclonal antibody was observed in 98.6% and by an anti-MUC1 monoclonal antibody in 76.8% of the patients. In relation to the application of cancer-specific immunotherapy, these findings provide useful information for determining the efficacy of MUC1- and WT1-targeted therapy.

A resected case of neuroendocrine carcinoma of the stomach with unusual lymph node metastasis.

Gastric endocrine cell carcinoma is a relatively rare tumor. We experienced a case of early gastric cancer in which an endocrine cell carcinoma was identified within a differentiated adenocarcinoma, and a component of this endocrine cell carcinoma had metastasized to lymph nodes of the stomach. In its 2010 revision regarding digestive system tumors, WHO classified cancer cells with characteristics of both glandular system cells and neuroendocrine cells as mixed adeno neuroendocrine carcinoma (MANEC) under the neuroendocrine carcinoma (NEC) category. In this case, we observed an endocrine cell carcinoma continuous with an intramucosal differentiated adenocarcinoma, and cancer cells with an irregular gland duct structure were observed in the proliferative portion of the submucosal tissue. In addition, there was a 35 mm size lymph node metastasis in the lesser curvature of the stomach consisting entirely of poorly differentiated cancer cells with polymorphic, highly atypical nuclei and scant cytoplasm. Immunohistological analysis showed that the endocrine carcinoma in the gastric mucosa was chromogranin A positive and the infiltrated area of the submucosal tissue was also chromogranin A positive. The lymph node metastasis was positive not only for chromogranin A, but also for Synaptophysin and CD56. Furthermore, the Ki67 labeling index was high at approximately 80 % for the gastric endocrine cell carcinoma and approximately 90 % for the lymph node metastases. Until now, there are no reports related to the patients with early gastric cancer accompanied with lymph node metastasis of MANEC. This case is very interested in considering the mechanism of lymph node metastasis of MANEC. The patient has shown no sign of recurrence for 1 year and 4 months after postoperative chemotherapy.

N-methyl-d-aspartate receptor coagonist d-serine suppresses intake of high-preference food.

d-Serine is abundant in the forebrain and physiologically important for modulating excitatory glutamatergic neurotransmission as a coagonist of synaptic N-methyl-d-aspartate (NMDA) receptor. NMDA signaling has been implicated in the control of food intake. However, the role of d-serine on appetite regulation is unknown. To clarify the effects of d-serine on appetite, we investigated the effect of oral d-serine ingestion on food intake in three different feeding paradigms (one-food access, two-food choice, and refeeding after 24-h fasting) using three different strains of male mice (C57Bl/6J, BKS, and ICR). The effect of d-serine was also tested in leptin signaling-deficient db/db mice and sensory-deafferented (capsaicin-treated) mice. The expression of orexigenic neuropeptides [neuropeptide Y (Npy) and agouti-related protein (Agrp)] in the hypothalamus was compared in fast/refed experiments. Conditioned taste aversion for high-fat diet (HFD) was tested in the d-serine-treated mice. Under the one-food-access paradigm, some of the d-serine-treated mice showed starvation, but not when fed normal chow. HFD feeding with d-serine ingestion did not cause aversion. Under the two-food-choice paradigm, d-serine suppressed the intake of high-preference food but not normal chow. d-Serine also effectively suppressed HFD intake but not normal chow in db/db mice and sensory-deafferented mice. In addition, d-serine suppressed normal chow intake after 24-h fasting despite higher orexigenic gene expression in the hypothalamus. d-Serine failed to suppress HFD intake in the presence of L-701,324, the selective and full antagonist at the glycine-binding site of the NMDA receptor. Therefore, d-serine suppresses the intake of high-preference food through coagonism toward NMDA receptors.

Improvement of Impaired Immunological Status of Patients with Various Types of Advanced Cancers by Autologous Immune Cell Therapy.

We evaluated the immunological status of patients with various solid tumors by flow cytometry of immune cell populations and their frequencies in peripheral blood samples. The change in immunological status was also analyzed in patients given autologous immune cell therapy, such as αßT cell, γδT cell, NK cell or DC vaccine therapy. The frequency of regulatory T-cells (Tregs) was shown to be high in patients with cancers of the lung (squamous carcinoma cells), head and neck, esophagus and uterus, although there were no significant differences in effector cell population or Th1/2 ratio between various types of cancers except for a few. The cellular immunological status was impaired in most patients with advanced solid tumors before immune cell therapy and the impaired T-cell immune status was restored by infusion of effector cells, such as αßT cells or γδT cells, although the number of NK cells in the peripheral blood did not always increase after autologous NK cell therapy. The concurrent αßT cell therapy and DC vaccine therapy could successfully increase the number of CD8(+) T-cells in the peripheral blood of patients with various types of cancers. Two or three injections of αßT cells could potentially reduce Tregs frequency prior to DC vaccine, as well as the concurrent αßT cell and DC vaccine therapy. However, an increase in the Tregs frequency was observed in some patients who received NK cell therapy. These findings suggest that it is necessary to include or combine certain types of immune cell therapy when the Tregs frequency of cancer patients is high before or after autologous immune cell therapy.

[Extranodal natural killer/T-cell lymphoma, nasal type developing central nervous system and epididymis involvement immediately after concurrent chemoradiotherapy].

A 66-year-old man showed central nervous system (CNS) and epididymis involvement after concurrent chemoradiotherapy for extranodal natural killer/T-cell lymphoma, nasal type (ENKL). The patient experienced continuous nasal obstruction. CT revealed a mass in the nasal cavity and paranasal sinuses. Biopsy of the nasal cavity mass showed it to be ENKL. Based on bone marrow biopsy and 18F-FDG PET/CT findings, the clinical stage was suspected to be IIE. The sites involved were the nasal cavity, paranasal sinuses, and cervical lymph nodes. We performed concurrent chemoradiotherapy consisting of a 67% dose of DeVIC and involved field radiation therapy towards his head and neck. Head and neck CT confirmed a therapeutic response. After receiving concurrent chemoradiotherapy, the patient complained of perineal discomfort. Ultrasonography revealed swelling of the left epididymis. Left epididymis biopsy showed ENKL involvement and lumbar puncture revealed CNS involvement. The findings of this case suggest that evaluation of CNS involvement might be an essential part of the initial workup for some ENKL patients.

Comparison of the conventional Macintosh laryngoscope, the Pentax Airwayscope, and the McGrath MAC video laryngoscope under restricted cervical motion: a manikin study.

Aim: We compared the utility of the conventional Macintosh laryngoscope, the Pentax Airway Scope, and the McGrath MAC video laryngoscope under restricted cervical motion using a manikin. Methods: We recruited 36 participants into the simulation study. The manikin's cervical motion was restricted with a cervical collar and a head immobilizer, as occurs in trauma cases. We recorded the time to intubation and the success rate of the intubations. Results: Data are medians and ranges. The time to intubation under normal and restricted cervical motion were 22.5 (10-78) and 23 (9-119) s with the Macintosh laryngoscope, 13.5 (5-50) and 14 (7-119) s with the Airway Scope, and 13 (6-32) and 18 (7-80) s with the McGrath MAC video laryngoscope. The differences in the time to intubation between normal and restricted cervical motion were significant only with the McGrath MAC (P = 0.0008). With restricted cervical motion, the times to intubation in the Airway Scope attempts were significantly shorter than those in the Macintosh laryngoscope (P = 0.0005) and McGrath MAC (P = 0.0282) attempts. The success rates under normal and restricted cervical motion were 100% and 80.6% with the Macintosh laryngoscope (P = 0.0054), 100% and 100% with the Airway Scope, and 100% and 97.2% with the McGrath MAC, respectively. Conclusion: In the present study, the Airway Scope was the best among the three devices. However, the differences between the Airway Scope and the McGrath MAC video laryngoscope may not be serious in a clinical situation. Data were gathered using a manikin, and further studies will be necessary.

Healthy baby delivered vaginally from a brain-dead mother.

Case: A pregnant (20 gestational weeks) 32-year-old woman was found in cardiac arrest. Spontaneous circulation returned after 15 min. She became brain dead on the 13th hospital day. The patient was in stable circulatory condition under nasal desmopressin and 20-30 mg/day of hydrocortisone. On the 92nd hospital day at gestational week 33 + 3 days, natural labor began and a healthy 2,130-g girl (Apgar 6/8) was delivered vaginally with minimum assistance. Outcome: The baby was discharged 40 days after birth and followed up regularly. Conclusion: Brain death remains a hopeless condition for patients, but a brain-dead woman may still be able to naturally deliver a healthy baby.
