We summarized the experience of surgical stabilization of rib fractures (SSRF) at a core hospital in eastern Hiroshima, which is a primary center for tertiary emergency medical care, especially for high-energy trauma cases including chest injuries. The study focuses on patients who underwent SSRF from January 2016 to September 2023, analyzing patient characteristics, injury mechanisms, associated injuries, fracture locations, time from injury to surgery, fixation devices used, and postoperative outcomes. Our hospital primarily treats elderly patients, and falls are the most common cause of injury, followed by traffic accidents. The criteria for SSRF in our hospital were clinical manifestations of flail chest, need for lung repair, persistent pain, or improvement of thoracic deformity. We had a high rate of fixation of fractures of the 4th-10th ribs, which have a significant impact on respiratory mechanics; although KANI plates were primarily used, the introduction of MatrixRIB plates offers advantages in certain scenarios. The study also identified challenges with the KANI plate, including cases of plate dislodgement, particularly in patients with multiple fractures and severe thoracic deformities. The combination of video-assisted thoracoscopic surgery and SSRF allows for more effective rib fixation and reduces surgical wound size and muscle damage.

Background: Penetrating thoracic trauma with coronary artery transection is a lethal injury, but is rare. We report a case of a cardiac stab wound with coronary artery transection that was successfully treated after preoperative diagnosis. Case Presentation: A 36-year-old man was transferred to our emergency department with a left chest stab wound. A coronary computed tomography-angiography scan, including coronary angiography, revealed left hemopneumothorax and left anterior descending branch transection, with ischemic changes in the left ventricular myocardium. Given the diagnosis of coronary artery transection and the absence of injury to the surrounding arteries, we were able to perform coronary artery bypass surgery using the left internal thoracic artery. The patient's postoperative course was good, and he was discharged on foot without major complications 18 days after surgery. Conclusion: Unless a resuscitative thoracotomy is required, a preoperative computed tomography scan, including coronary angiography, may be useful for accurate preoperative diagnosis for patients at high risk of myocardial or coronary artery injury.
BACKGROUND: Bronchial artery aneurysm (BAA) is a rare vascular anomaly with the potential for serious complications, such as rupture leading to hemothorax or hemoptysis. Although bronchial artery embolization (BAE) is recognized as an effective intervention for ruptured BAA, video-assisted thoracoscopic surgery (VATS) is a minimally invasive approach for the treatment of associated hemothorax. CASE PRESENTATION: A 73-year-old woman presented with a mediastinal hematoma from a ruptured BAA, causing bilateral hemothorax. Emergency angiography revealed a saccular BAA that was successfully embolized using a microcatheter and coil. Subsequent computed tomography revealed an expanding hemothorax managed by VATS, with 1400 mL of blood drained. During VATS, thoracoscopy revealed pulmonary ligament rupture, which was attributed to increased intramediastinal pressure. The patient was discharged eight days postoperatively with no complications. This case highlights the use of BAE and VATS in the management of mediastinal BAA rupture and massive hemothorax. CONCLUSIONS: BAE proved to be an effective strategy for the management of ruptured mediastinal BAAs. VATS is a valuable standby procedure for hematoma removal, but the indication should be carefully determined because of the risk of BAA re-rupture.
A 78-year-old man with prostate squamous cell carcinoma recurrence in his pelvis was admitted to our hospital. Rectal obstruction led to creation of an artificial anus on the transverse colon. Then, docetaxel and radiation therapies were started. A week later, severe hematuria and melena occurred. Activated partial thromboplastin time (APTT) and prothrombin time (PT) were extremely prolonged. Cross-mixing test for APTT and PT revealed an inhibitor pattern, which was diagnosed as acquired factor V inhibitor. Fresh frozen plasma and vitamin K infusions were ineffective, but platelet transfusion successfully stopped the bleeding. Platelet factor V derived from megakaryocytes may affect local hemostasis. The patient received prednisolone (PSL), and the inhibitor disappeared on day 70 and was in remission. PSL could be stopped on day 100. Later, we demonstrated APTT and PT shortening of factor V deficient plasma by the supernatant of activated platelets with collagen.

Background: Acute pancreatitis triggered by causative agents, including alcohol consumption, gallstones, dyslipidemia, drugs, and infection, is frequently addressed. However, reports of acute pancreatitis caused by duodenal bezoars are limited. Case Presentation: A 75-year-old man experiencing abdominal pain and frequent vomiting was transferred to our hospital. His medical records presented history of diabetes, hypertension, dyslipidemia, and gastric cancer surgery. Computed tomography of the abdomen indicated duodenal dilatation, enlarged pancreas, and fluid retention, with no bile duct stones present. Minor bleeding and duodenal bezoar were endoscopically detected with esophagogastroduodenoscopy (EGD). He was diagnosed with severe acute pancreatitis caused by a bezoar and admitted to the intensive care unit. The duodenal bezoar was dissected and removed with three repetitions of EGD, and the patient was discharged without any complications. Conclusion: Herein, we report a case showing that endoscopic procedures could be effective treatment options in severe pancreatitis caused by duodenal bezoars.
The COVID-19 pandemic has posed severe restrictions on daily mobility for people globally. We use a monthly household panel dataset that covers a period both before and after the outbreak began to examine the impact of COVID-19 on daily mobility and household welfare in Tajikistan. The feature of our dataset is that it contains information on daily mobility for those traveling by vehicle along with their travel purposes. We provide several new findings. First, the impact of the pandemic on daily mobility was limited in Tajikistan, in contrast with the evidence from other countries. The pandemic discouraged motorized travel for family-related purposes in all income groups while keeping other vehicle travel intact for reasons such as work and shopping under the country's lenient travel restrictions. Second, the effects of concerns about the pandemic were not uniform across all vehicle travel when different purposes are taken into account. People who were very concerned about the pandemic were more likely to refrain from motorized travel for family-related purposes. Third, refraining from travel for family purposes exacerbated food insecurity, implying that the safety net provided by family members and relatives was hampered by the limited ability to travel during the pandemic.
We report the autopsy findings of a case of disseminated mucormycosis caused by Cunninghamella bertholletiae, a rare pathogenic fungus of the family Mucoraceae. The patient was a 49-year-old woman with B-lymphoblastic leukemia with hyperdiploidy, who died of progressive heart failure 4 months after induction chemotherapy successfully brought about complete remission of the leukemia. Granulocyte colony-stimulating factor (G-CSF) had been administered along with anti-neoplastic drugs, and her blood neutrophil count was markedly elevated. Autopsy revealed disseminated mycotic thromboembolism and abscess formation in the heart, lung, liver, kidney, and spleen. The most marked feature was a large mural thrombus in the left ventricle containing numerous fungal hyphae. In the myocardium and disseminated foci in visceral organs, giant cell-rich, fibrotic reactions to the mycotic infection were observed. Both the formation of a large intra-ventricular mural thrombus and giant cell reactions are rare findings in mucormycosis. We considered that the recovery and marked increase in neutrophil count induced by chemotherapy and G-CSF administration prolonged the clinical course and pathologically elicited an atypical, giant cell reaction to the mycotic infection. The prolonged clinical course also contributed to the formation of an unusually large intra-ventricular mural thrombus.
A 41-year-old man with exertional dyspnea was referred to our hospital. Chest computed tomography (CT) showed a pulmonary arteriovenous malformation (PAVM) in the left lingular lobe, and magnetic resonance imaging showed a brain abscess. After antimicrobial therapy, the patient underwent thoracoscopic lingulectomy of the PAVM. Pathological examination revealed lung metastases of papillary thyroid cancer (PTC) that were undetectable by CT. The patient underwent total thyroidectomy and D2b lymphadenectomy for the PTC (the pathological stage was T1bN2M1, Stage II). After surgery, the patient received 100 mCi of 131Iodine; post-treatment scans revealed only neck (remnant) uptake and the patient continued with thyroid hormone replacement therapy. To the best of our knowledge, this is the first report of a case of combined PAVM and occult lung metastases of PTC. Clinicians should remember that they may detect micro lung metastases of any cancer when investigating resected lung specimens.
The COVID-19 pandemic is likely to have adverse effects on the economy through damage to migration and remittances. We use a unique monthly household panel dataset that covers the period both before and after the outbreak to examine the impacts of COVID-19 on a variety of household welfare outcomes in Tajikistan, where remittance inflows in recent years have exceeded a quarter of annual GDP. We provide several findings. First, after April 2020, the adverse effects of the pandemic on household welfare were significantly observed and were particularly pronounced in the second quarter of 2020. Second, in contrast to expectation, the pandemic had a sharp but only transitory effect on the stock of migrants working abroad in the spring. Some expected migrants were forced to remain in their home country during the border closures, while some incumbent migrants expecting to return were unable to do so and remained employed in their destination countries. Both departures and returns started to increase again from summer. Employment and remittances of the migrants quickly recovered to levels seen in previous years after a sharp decline in April and May. Third, regression analyses reveal that both migration and remittances have helped to mitigate the adverse economic outcomes at home during the "with-COVID-19" period, suggesting that they served as a form of insurance. Overall, the unfavorable effects of the COVID-19 pandemic were severe and temporary right after the outbreak, but households with migrants were more resilient against the pandemic.

BACKGROUND AND AIM: Many patients are not satisfied with chronic constipation (CC) treatments. The aim of this study was to identify factors linked to CC treatment satisfaction or dissatisfaction. METHODS: Our study population included patients who received CC treatment at a clinic or hospital. CC was diagnosed by a physician based on the patient's complaint. Treatment satisfaction was evaluated using the 28th question of the Patient Assessment of Constipation Quality of Life questionnaire. RESULTS: We conducted this study at 28 facilities. We included 167 patients (mean age 66.7 ± 15.2 years, male:female ratio is 1:3.07). Sixty-eight (40.7%) of patients were satisfied with their constipation treatment. Treatment dissatisfaction of CC was significantly associated with frequency of bowel movement <3/week (odds ratio [OR] = 0.376, 95% confidence interval [CI]: 0.156-0.904, P = 0.029) or Bristol Stool Form Scale (BSFS) type 3 (OR = 0.401, 95% CI: 0.170-0.946, P = 0.037). CONCLUSIONS: Our study showed that CC patients with BSFS type3 were not satisfied with constipation treatment. In general, BSFS types 3-5 are defined as normal stools. Therefore, BSFS type 3 may be set as a treatment goal even though the patient is not satisfied. The pathophysiology of CC differs by region and patient background. Therefore, parameters used to define successful treatment will be different by patient or region. We should reconsider the positioning of BSFS type 3 to improve treatment satisfaction for CC.

STUDY DESIGN: Retrospective radiological comparative design. PURPOSE: To investigate whether conventional magnetic resonance imaging (MRI) could substitute three-dimensional (3D)-MRI for the calculation of the foraminal stenotic ratio (FSR) and clarification of which patients can be assessed more accurately using 3D-MRI. OVERVIEW OF LITERATURE: Previous studies have indicated that 3D-MRI is useful for diagnosing lumbar foraminal stenosis. The FSR obtained using 3D-MRI, described as the ratio of stenosis length, characterized by perineural fat obliteration, to the length of the entire foramen, could indicate the stenosis severity; however, this method is time-consuming and expensive. The FSR also can be calculated using conventional MRI. METHODS: We investigated 154 foramina at L5-S1 in 77 patients. All the patients had degenerative lumbar disorders and had undergone both conventional MRI and 3D-MRI during the same visit. Differences between the FSRs calculated from conventional and 3D-MRI reconstructions and any correlations with the plain radiography findings were assessed. RESULTS: In foramina that had a FSR of <50% on conventional MRI, the difference between the FSR obtained using conventional MRI and 3D-MRI was 5.1%, with a correlation coefficient of 0.777. For foramina with a FSR ≥50% on conventional MRI, the difference was 20.2%, with a correlation coefficient of 0.54. FSR obtained using 3D-MRI was significantly greater in patients who required surgery than in those who were successfully treated with conservative methods (88% and 42%, respectively). Segments with spondylolisthesis or lateral wedging showed higher FSRs than those without these conditions on both types of MRI. CONCLUSIONS: FSRs <50% obtained using conventional MRI were sufficiently reliable; however, the results were inaccurate for FSRs ≥50%. Patients with high FSRs on 3D-MRI were more likely to require surgical treatment. Therefore, 3D-MRI is recommended in patients with suspected stenosis detected using conventional MRI or plain radiographs.
The Coronavirus Disease 2019 (COVID-19) is inevitably affecting remittance-dependent countries through economic downturns in the destination countries, and restrictions on travel and sending remittances to their home country. We explore the potential impacts of the COVID-19 pandemic on the welfare of remittance-dependent households using a dataset collected in the Philippines prior to the outbreak. First, we confirm that remittances are associated with welfare of households, particularly for those whose head is male or lower educated. Then, we use the revision of the 2020 GDP projections before and after the COVID-19 crisis to gauge potential impacts on households caused by the pandemic. We find that remittance inflow will decrease by 14-20% and household spending per capita will decline by 1-2% (food expenditure per capita by 2-3%) in one year as a result of the pandemic.
Carcinoid arising from a mature cystic teratoma of the mediastinum is extremely rare. A 30-year-old man complaining of chest pain was admitted to our hospital for abnormal shadow in right mediastinum on chest tomography. Computed tomography (CT) and magnetic resonance imaging (MRI) suggested mature teratoma. Complete resection under video-assisted thoracotomy was performed. The postoperative course was uneventful. Histological diagnosis was mature cystic teratoma containing 3 mm component of carcinoid in the capsule. There were no pathological findings of necrosis and MIB-1-index was 1 %. No recurrence has been observed for 7 months after surgery.

We analyzed 197 fall incidents in the questionnaire survey about the incident that occurred in Department of Radiology. In the past paper about the patient safety, there is no report that evaluated incident data directly. The purpose of this paper is to analyze the factor of the medical incidents using statistical technique scientifically. In this paper, we do not suggest concrete precaution. At first, we found the number of patients (each gender, modality, generation) in the five facilities of the coworker of one week. We found an incident rate from this patient total number, and we normalized data. As a result, we were able to do each risk evaluation because a risk ratio and relative risk degree was found. And, we were able to identify modality and the generation with the significant difference using the testing for differences in population rate. By our analyses, we revealed the chapter which must strengthen safety management.

PURPOSE: The purpose of this study is to analyze the factors of patient's fall that causes serious injury in the radiological examinations. METHODS: We conducted a questionnaire survey on cases of medical accidents occurring in the radiological examination department in medical institutions. The number of responses to the questionnaire surveys was 372. Among them, 197 cases were related to fall. The incident influence classification divided into eight clusters (0, 0H, 1, 2, 3a, 3b, 4, 5) was divided into three clusters (tiny, moderate, serious injury) depending on severity. We analyzed the factors that cause serious injury. RESULTS: In the case of patient's fall, several factors have been found to cause serious injury. The factors were general radiography, standing position, outside working hours. CONCLUSION: All falls can cause serious injury. To reduce falls, it is important to analyze what kind of patient and in what situation tend to fall, and prevent falls in advance.

We conducted a questionnaire survey (situation, patient factor, environmental factor, operator factor, degree of disability, countermeasure etc.) on cases that occurred up to the present to investigate the actual situation of the medical accidents that occur in the radiological examination department of medical institutions. There were 373 questionnaires collected. Among them, there were 197 cases of falls. In this study, we examined the age of patients who fell, the background of the accident, and factors. As for the accident, 11.7% of accidents with risk impact level 3b or higher occurred including the fatal accident. Of the accidents, 44.2% were foreseeable and 55.8% were unforeseeable. The most accident-prone age was elderly in their 60s to 80s. As the causative factor for the accident, the patient factor was the largest at 63.5%. We can prevent about 30% of the accident by improving the operator factor and the environmental factor which are parts other than patient factor. It is important for us to understand what kind of people tend to fall. Among foreseeable accidents, the causes of patient factors can be reduced.

PURPOSE: The purpose of this paper is to analyze the characteristics of incidents related to routes and drains that occur in the radiological examination room for the prevention of these incidents. METHODS: We conducted a questionnaire survey on incident cases that occurred in the radiological examination room. There were 373 responses, of which 76 responses were related to routes and drains. The question contents were the number of hospital beds, radiology department of occurrence, time of occurrence, patient's situation, method of visiting, years of experience of the radiological technologists, and countermeasures, and so on. Based on these answers to these questions, we analyzed which factors were involved in the occurrence of the incidents. RESULTS: Incidents related to routes and drains often occur when moving examination table or transferring the patients to the examination table using the slider. On the other hand, the years of experience of the radiological technologists hardly participated in the factor of these incidents. From these answers to questions, 75% of incidents might predictable, and these incidents could be prevented by improvement of human factors accounted for the majority rather than that of physical factors. CONCLUSION: The number of incidents related to routes and drains may reduce by that all staff involved in the radiological examination recognizing the characteristic of these incidents.

An 85-year-old male patient was referred to our hospital for further examination of a liver tumor. Imaging examination revealed a 90-mm tumor in segment 4/8 and 30-mm tumor in segment 6 of the liver. Histopathological examination revealed that the tumor in segment 4/8 was cholangiolocellular carcinoma (CLC) and the tumor in segment 6 was hepatocellular carcinoma (HCC). This case shows that although the frequency of CLC is very low, recent studies have indicated the novel knowledge of CLC. Herein, we report a surgical case of CLC and HCC in the background of resolved hepatitis B virus infection.

A 69-year-old man who arrived at our hospital by ambulance with dyspnea was diagnosed with pneumothorax. The chest was drained, but the left lung failed to expand due to air leakage. A pulmonary fistula in the left lower lobe identified by video-assisted thoracic surgery was repaired. Postoperative chest radiography showed inadequate expansion of the left upper lobe. Bronchoscopy revealed an obstruction of the left upper bronchus that was pathologically diagnosed as squamous cell carcinoma. Enhanced computed tomography revealed a central tumor with atelectasis of the left upper lobe, and a stained node in the left lower lobe. Clinical T4N1M0 stage III A lung cancer was confirmed. The patient was treated with concurrent chemoradiotherapy. It was likely that the lung cancer in the upper bronchus caused the atelectasis, leading secondary expansion of the lower lobe and the rupture of a bulla.

Background and objective: Phase difference enhanced imaging (PADRE), a new phase-related MRI technique, can enhance both paramagnetic and diamagnetic substances, and select which phases to be enhanced. Utilizing these characteristics, we developed color map of PADRE (Color PADRE), which enables simultaneous visualization of myelin-rich structures and veins. Our aim was to determine whether Color PADRE is sufficient to delineate the characteristics of non-gadolinium-enhancing T2-hyperintense regions related with metastatic tumors (MTs), diffuse astrocytomas (DAs) and glioblastomas (GBs), and whether it can contribute to the differentiation of MTs from GBs. Methods: Color PADRE images of 11 patients with MTs, nine with DAs and 17 with GBs were created by combining tissue-enhanced, vessel-enhanced and magnitude images of PADRE, and then retrospectively reviewed. First, predominant visibility of superficial white matter and deep medullary veins within non-gadolinium-enhancing T2-hyperintense regions were compared among the three groups. Then, the discriminatory power to differentiate MTs from GBs was assessed using receiver operating characteristic analysis. Results: The degree of visibility of superficial white matter was significantly better in MTs than in GBs (p = 0.017), better in GBs than in DAs (p = 0.014), and better in MTs than in DAs (p = 0.0021). On the contrary, the difference in the visibility of deep medullary veins was not significant (p = 0.065). The area under the receiver operating characteristic curve to discriminate MTs from GBs was 0.76 with a sensitivity of 80% and specificity of 64%. Conclusion: Visibility of superficial white matter on Color PADRE reflects inferred differences in the proportion of vasogenic edema and tumoral infiltration within non-gadolinium-enhancing T2-hyperintense regions of MTs, DAs and GBs. Evaluation of peritumoral areas on Color PADRE can help to distinguish MTs from GBs.
