Tracheal resection in post COVID-19 patients is associated with high reintervention rate and early restenosis. JTCVS Tech 2023; 18:157-163. [PMID: 36685052 PMCID: PMC9846877 DOI: 10.1016/j.xjtc.2023.01.006] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2022] [Revised: 11/21/2022] [Accepted: 12/20/2022] [Indexed: 01/19/2023] Open
Abstract
Objectives A remarkable increase in the number of patients presenting with tracheal complications after prolonged endotracheal intubation and mechanical ventilation for the management of the severe COVID-19 - associated respiratory failure has been observed. In this study, we assessed the postoperative outcomes of tracheal resection in COVID-19 patients. Methods We conducted a retrospective study in which all patients with a history of prolonged invasive mechanical ventilation due to COVID-19 infection, who were treated with tracheal resection and reconstruction, were included. The primary objective was in-hospital mortality and postoperative reintervention rate. The secondary objective was the time to tracheal restenosis. Results During the 16-month study period, 11 COVID-19 patients with tracheal complications underwent tracheal resection with end-to-end anastomosis. Mean patient age was 51.5 ± 9 years, and the majority were male (9 patients). Eight patients were referred for management of post-intubation tracheal stenosis and 3 for tracheoesophageal fistula. Eight patients had a history of tracheostomy during the COVID-19 infection hospitalization. There was one in-hospital death (9.1%) due to septicemia in the Intensive Care Unit, approximately two months after the operation. Postoperatively, 32 reinterventions were required for tracheal restenosis due to granulation tissue formation. The risk for reintervention was higher during the first 3 months after the index operation. Four patients developed tracheal restenosis (36.4%) and two of them required endotracheal stent placement during the follow up period. Conclusions Tracheal resection and reconstruction after COVID-19 infection is associated with a high reintervention rate postoperatively. Such patients require close follow up in expert interventional pulmonology units and physicians should be on high alert for the early diagnosis and optimal management of tracheal restenosis.

[PMID: 36747927 PMCID: PMC9898674 DOI: 10.1016/j.heliyon.2023.e13004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2022] [Revised: 01/12/2023] [Accepted: 01/12/2023] [Indexed: 01/19/2023] Open
Abstract
Rationale and objectives To evaluate the usefulness of temporal subtraction using the bone suppression method in digital chest radiography for the detection of pulmonary lesions. Materials and methods The images of 31 patients with pulmonary lesions and 19 normal cases were included in the study. Conventional and bone suppression temporal subtraction were performed in the 50 cases selected and used for an observer performance study. Five radiologists participated in the study, and the differences between using conventional and bone suppression temporal subtraction were assessed using jackknife free-response receiver operating characteristic analysis. Results The average figure-of-merit values for all radiologists increased significantly using the bone suppression method, from 0.619 (conventional) to 0.696 (p = 0.032). The average sensitivity for detecting pulmonary lesions improved from 67.9% to 75.4%, and the average number of false-positive per case decreased from 0.336 to 0.252 using bone suppression temporal subtraction. Conclusion Bone suppression temporal subtraction processing can assist with the detection of subtle pulmonary lesions in digital chest radiographs.

Heliyon 2023; 9:e12960. [PMID: 36711283 PMCID: PMC9876943 DOI: 10.1016/j.heliyon.2023.e12960] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2022] [Revised: 12/27/2022] [Accepted: 01/10/2023] [Indexed: 01/17/2023] Open
Abstract
Background Giant cystic meconium peritonitis (MP) is a relatively rare entity. Prompt surgical treatment is required to manage the underlying etiology and reestablish the continuity of the intestines. Despite perinatal and postoperative care improvements, the overall mortality rate is still relatively high. We reported a giant cystic MP that was recognized using antenatal sonography (US). It was successfully treated with primary anastomosis. Case presentation We presented a female newborn with a chief complaint of abdominal mass. The prenatal sonography showed an intraabdominal cyst at the 28th week of gestation. She was born at the gestational age of 38 weeks via vaginal delivery from a primigravid mother without complications, with a birth weight of 3275 g. Elective surgery was performed at the age of eight days, and a calcified 10 cm cyst was revealed along with severe adhesions. The cyst was found to communicate with the ileum located 30 cm proximal from the ileocecal junction. No malrotation and volvulus were found. The cyst and a portion of the ileum were resected, followed by a primary end-to-end anastomosis. Pathologic examination showed necrotic tissue lined with epithelial tissue with microcalcifications containing bilirubin pigments, consistent with cystic MP. The patient has uneventfully discharged on postoperative day 17. The patient has normal growth and development, except for delayed walking, at the last follow-up of two years of age. Conclusion Giant cystic MP is a rare disorder that can be detected early using the antenatal US. Our case highlights the importance of early diagnosis for giant cystic MP using the antenatal US leads to prompt surgical treatment and a more favorable prognosis.

Abstract
Iatrogenic bile duct injuries remain a substantial problem in gastrointestinal surgery, especially if discovered later in the postoperative period. Herein, we report a case of an unusual bile leak following laparoscopic cholecystectomy consisting of an isolated right segmental hepatic duct injury of segment 5 together with an additional bile leak of a small duct connecting the gallbladder fossa with the common bile duct. We call this situation an incomplete isolated right segmental hepatic duct injury. Patient presented with infected biloma 2 weeks after laparoscopic cholecystectomy. After percutaneous drainage of the biloma and antibiotic therapy the complex biliary fistula was closed first with coil embolization of the small connection to the common bile duct and then with both antegrade and retrograde histoacryl embolization of the hereby created complete isolated right segmental hepatic duct injury in a single session. Patient was discharged the same day and recovered without complication or recurrence.

Abstract
Epigastric abdominal pain is a common indication for consultation. In the majority of cases, medical history, clinical examination and routine biological exams allow for an easy diagnosis. Sometimes the symptomatology is unusual, in which case it is essential to perform a complete clinical examination and to use various imaging techniques to search for eventual atypical causes. Membranous obstruction of inferior vena cava is a rare cause of such a phenomenon. We describe a Budd-Chiari syndrome caused by membranous obstruction of inferior vena cava in a 66-year-old woman with no medical history as a rare cause of epigastric abdominal pain. We will describe this clinical experience in the light of the literature and point out the contribution of radiological imaging in the diagnosis of this rare pathology.

Abstract
Percutaneous paravalvular leak closure seems a safe alternative to surgery in frail patients. However, it is a challenging procedure that should be tailored to each patient with optimal imaging guidance. Transesophageal echocardiography during the procedure and computed tomography scan/fluoroscopy fusion provide guidance for critical steps, such as PVL localization and crossing.

Abstract
Adult T-cell leukemia/lymphoma (ATLL) is a human T-cell leukemia virus type 1-inducing unevenly-distributed T-cell malignancy, which is often complicated by opportunistic infections. Here, we discuss the case of a 75-year-old woman presenting with Pneumocystis pneumonia (PCP) who was subsequently diagnosed with ATLL in Tokyo, a non-endemic area of ATLL. In addition to the elevated soluble interleukin-2 receptor and the detection of flower cells in the screening blood test, the high-resolution computed tomography findings, atypical of PCP, were clues to the diagnosis of ATLL. ATLL should be considered as an underlying disease when patients present with PCP, even in non-endemic areas.

Abstract
Background There is still no gold standard treatment for Neer type V distal clavicle fractures. This study was designed to evaluate the therapeutic effects of accelerated rehabilitation in treating Neer type V fractures using anatomical locking plate (ALP) fixation with additional coracoclavicular (CC) ligament augmentation. Methods In this retrospective study, patients who underwent ALP fixation with additional suture anchor fixation of acute Neer type V distal clavicle fracture from January 2016 to January 2021 were reviewed. Injury radiography and computed tomography (CT) were performed to determine the Neer classification. All patients performed standardized early rehabilitation exercises after surgery and were followed up for more than 12 months. The Constant-Murley score (CMS); the disabilities of the arm, shoulder, and hand (DASH) questionnaire; visual analog scale (VAS); and the percentage of modified CC distance (MCCD%) were evaluated at the last follow-up. Results Thirty-two patients were included in this study. The mean follow-up time was 31.1 ± 10.4 months. All patients achieved bone union 6-8 weeks (7.2 ± 0.7 weeks) after surgery and were allowed to return to normal daily life. No surgery-related complications occurred in any case. The MCCD% value at the last follow-up (104.7% ± 8.5%) significantly decreased compared with preoperative MCCD% value (162.8% ± 7.2%) (p < 0.001), indicating that all patients achieved ideal fracture reduction. And all patients obtained satisfactory shoulder joint function with a mean CMS of 97.1 ± 2.6, a mean DASH score of 1.6 ± 1.3, and a mean VAS score of 0.4 ± 0.6. Conclusion This study has demonstrated that ALP fixation with additional suture anchor fixation is a promising strategy for accelerated rehabilitation in treating patients with Neer type V fracture.

Abstract
Aspergillus infectious endocarditis (IE) is a rare cause of culture-negative endocarditis. The main risk factors are severe immunosuppression and prosthetic heart valve. We describe a case of Aspergillus fumigatus IE on a native mitral valve in a patient with autoimmune hepatitis in remission while on low dose corticosteroids. The case is unique due to the patients' low initial risk for invasive fungal disease, its clinical presentation and successful management with emergency surgery and antifungal therapy. After literature review we have not found a similar case report. The patient presented with right-sided eyesight deterioration due to endophthalmitis. Vitrectomy was performed and Aspergillus fumigatus grew on culture. IE on a native mitral valve was confirmed with echocardiography. The patient developed signs of acute heart failure soon after hospital admission and was diagnosed with several septic emboli (kidney, spleen, thumb, right common femoral artery). He was initially treated with surgical valve replacement, dual antifungal therapy with liposomal amphotericin B (LAmB) and voriconazole and vitrectomy, including intravitreal amphotericin B application. Long-term triazole therapy was not possible due to hepatotoxicity. The patient was maintained on intermittent LAmB for 12 months and is without signs of recurrence ten months after therapy was discontinued. Aspergillus can cause invasive infection in patients with autoimmune hepatitis on low dose corticosteroids. Early diagnosis followed by emergency surgical valve replacement and systemic antifungal therapy can improve prognosis. Additional studies are needed to evaluate alternative methods and duration of antimicrobial therapy following Aspergillus IE.

Abstract
Objective Multiple alternative approaches of cochlear implant surgery have been described, such as the suprameatal approach, transcanal approach, transmeatal approach and middle cranial fossa approach. Transmeatal (open trnascanal) approach has not been adapted since first described in the clinical field. we aimed to assess the long-term complications of the transmeatal approach in a series of 131 patients at our center between 2004 and 2008. Methods This study was a retrospective case series of all patients who underwent cochlear implants with the transmeatal (open transcanal) approach from May 2004 to December 2008 at King Faisal Specialist and Research Hospital (Riyadh, Saudi Arabia), which were conducted by the same surgeon. Results Complications were observed often with various combinations-recurrent otitis externa, posterior tympanic membrane perforation, electrode extrusion, cholesteatoma, and chronic mastoiditis. The overall long-term complication rate was 16% (21/131). The gap between the implantation and the diagnosis of a complication ranged from <1 year to 11 years. Major complications were as follows: cholesteatoma in 5 (3.8%) patients, extrusion of the electrode in 5 (3.8%) patients, and tympanic membrane perforation or deep retractions in 5 (3.8%) patients. Minor complications were as follows: recurrent mastoiditis with/without concomitant temporary facial nerve palsy in 4 (3%) patients, recurrent otitis externa infections in 7 (5%) patients, and weakness of the posterior canal wall in 1 patient. Conclusion The transmeatal approach posed an high rate of complications on long-term follow-up such as cholestetoma formation, extrusion of electrode or perielectrode reaction formation to tympanic membrane and external auditory canal.

Abstract
Incidence of chylothorax post-esophageal stenting has not been reported. We present a 40-year-old female with metastatic breast cancer who presented with dyspnea. She was recently hospitalized for dysphagia secondary to a mediastinal mass requiring an esophageal stent. CT chest now reported large bilateral pleural effusions. A benign chylothorax was drained from the right side. After persistent high-output drainage, a review of her CT chest revealed thoracic duct impingement by the esophageal stent. The stent was retracted proximally, and pleural fluid output subsequently decreased. Repeat fluid analysis revealed a transudative effusion. This is the first reported case of esophageal stenting causing reversible chylothorax.

Abstract
Background Total hip arthroplasty (THA) for hip disorders helps to alleviate pain and improve active daily life. When determining the effects of medical therapy and the subsequent clinical results, patient quality of life (QOL) also needs to be assessed. Recently, patient-reported outcomes (PRO) have become important as evaluation criteria. This study aimed to evaluate patient QOL and various PRO between different types of cementless stems and to clarify the relationship between PRO and stem-cortical bone contact. Methods The study comprised 138 consecutive patients undergoing cementless THA for hip osteoarthritis. We assessed three different types of PRO: the Japanese Orthopaedic Association Hip-Disease Evaluation Questionnaire (JHEQ), patient's joint perception, and peri-hip articular joint pain (PHAP). We measured the state of contact between femur and implant by density mapping. Results No significant difference was noted in PRO between stem types based on the JHEQ and patient's joint perception. PHAP occurred more frequently in the patients with a taper wedge stem versus a fit-and-fill stem. In both groups, distal contact was associated with PHAP but not with JHEQ results and patient's joint perception. Conclusion The difference in PHAP between the two stem types groups was significant, with postoperative PHAP being higher with the taper wedge stem because of the more distal contact between the taper wedge stem and femur cortical bone.

Abstract
Purpose The optimal choice of protocol for diagnostic imaging in children with tuberculosis (TB) is a contemporary challenge due to the war in Ukraine, which potentially can create a steep rise in TB cases in Western Europe. We aimed to gather all primary research comparing imaging modalities and their diagnostic accuracies for pulmonary findings in children with suspected or confirmed pulmonary tuberculosis (PTB). Method We searched the databases PubMed and Embase using pre-specified search terms, for English- and non-English published and un-published reports from the period 1972 to 2022. We retrieved reports via citation search in excluded literature reviews and systematic reviews. Studies were eligible if most of the study population was between 0 and 18 years of age with confirmed or suspected PTB, and study participants had described diagnostic images from two or more different imaging modalities. Results A total of 15 studies investigated conventional chest X-Ray (CXR) and computed tomography (CT) in diagnosing PTB in children. Nine studies investigated the number of participants in where CT or CXR confirmed the diagnosis of TB, and all of them, including a total of 1244 patients, reported that findings compatible with TB were more frequently detected on CT than CXR. Only two studies did not include radiological findings as part of their diagnostic criteria for PTB, and combined they showed that CT diagnosed 54/54 (100 %) children with confirmed PTB, while CXR diagnosed 42/54 (78 %). Two studies compared magnetic resonance imaging (MRI) with CXR and showed that MRI diagnosed more children with PTB than CXR. One study reported a higher positive predictive value (PPV), sensitivity and specificity for PTB findings for MRI than CXR. One study compared CXR with high-kilovolt (high-kV) CXR, finding compatible sensitivity and specificity regarding confirmation of PTB. Two studies compared ultrasound (US) with CXR and found that US had a higher diagnostic yield and more often correctly identified consolidations, mediastinal LAP, and pleural effusion. Conclusion CT showed a higher diagnostic accuracy for PTB findings than CXR, MRI and US, and should be the imaging modality of first choice when available. MRI had a higher sensitivity and specificity than CXR for LAP, pleural effusion, and cavitation. US was complimentary in initial diagnostic work-up and follow up. A diagnostic strategy for PTB in children according to local availability and expertise is proposed, as no evidence from this systematic review shows otherwise, in acknowledgement of the expertise in high TB-burdened countries. CT can be performed when in doubt, due to the higher diagnostic yield.

JACC Case Rep 2022; 7:101711. [PMID: 36776792 PMCID: PMC9911917 DOI: 10.1016/j.jaccas.2022.101711] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Revised: 11/04/2022] [Accepted: 11/09/2022] [Indexed: 12/25/2022]
Abstract
We developed humanized biosimulator to predict the risk of coronary obstruction among high-risk patients undergoing valve-in-valve (ViV) procedures. In this case, based on unchanged instantaneous wave-free ratio values measured during a ViV simulation session, the procedure was performed safely in the patient the day afterward, without coronary artery issues and with good hemodynamic results. (Level of Difficulty: Advanced.).

Abstract
Background Bifidobacterium breve is an obligate anaerobic gram-positive bacillus mainly found in the gastrointestinal tract of human infants. Few cases of necrotizing fasciitis caused by B. breve have been reported. Case presentation A 42-year-old Japanese man with type 2 diabetes mellitus, obesity, cellulitis of the back, and subcutaneous abscess of the right inguinal region presented with rapidly developing erythema, swelling and severe pain in the right inguinal region. Computed tomography showed widespread gas in the right leg region. Cultures of blood and a swab of the wound abscess grew gram-positive bacilli. Mass spectrography and 16 S rDNA analysis confirmed the gram-positive bacilli as B. breve. The patient recovered following extensive debridement and antibacterial therapy. Conclusion Unidentified necrotizing fasciitis can be caused by B. breve, especially in compromised hosts.

Identification and characterization of patients being exposed to computed-tomography associated radiation-doses above 100 mSv in a real-life setting. Eur J Radiol Open 2022; 10:100470. [PMID: 36590327 PMCID: PMC9800257 DOI: 10.1016/j.ejro.2022.100470] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2022] [Revised: 12/16/2022] [Accepted: 12/20/2022] [Indexed: 12/24/2022] Open
Abstract
Rationale and objectives Patients receiving high cumulative effective doses (CED) from recurrent computed tomography (CT) in a real-life setting are not well identified. Evaluation of causes and patient characteristics may help to define individuals potentially at risk of radiation-induced secondary malignancies. Materials and methods Patients who received a CED > 100 mSv from CT scans during October 2012 and April 2020 at a tertiary university center were identified with the help of a radiological radiation dose monitoring system. The primary disease and referral diagnosis, number of CT exams, time period, age, BMI and gender distribution of the 1000 patients with the highest CED were analysed. Results 3431 patients had a CED of more than 100 mSv, which corresponded to 2.75% of all patients who received a CT exam. From the 1000 patients with the highest CED, mean number of CT exams per patient was 14.6, mean CED was 257 mSv (SD 98, range 177-1339). Mean age of patients was 63.9 years (SD 10.6), male to female ratio 3:2, and mean BMI 28.7 kg/m2 (SD 5.5). 728 (72.9%) patients had cancer. The leading primary diagnosis was liver cirrhosis in 197 patients and 103 patients had a liver transplantation. In patients with liver cirrhosis, 750 exams were indicated for the follow-up of the disease, 662 for the clarification of an acute clinical condition, and 202 for CT-guided stereotactic radiofrequency ablation. Conclusion Recurrent CT scans of patients with cancer, liver cirrhosis and liver transplantation may lead to critically high CED.

Abstract
Objective To describe the clinical and radiographic findings in a large cohort of patients with positive cultures for Nocardia emphasizing the differences between invasive disease and colonization. Patients and Methods We conducted a single-center, retrospective cohort study of 133 patients with a positive Nocardia isolate between August 1, 1998, and November 30, 2018, and a computed tomography (CT) of the chest within 30 days before or after the bacteria isolation date. Results Patients with colonization were older (71 vs 65 years; P=.004), frequently with chronic obstructive pulmonary disease (56.8% vs 16.9%; P<.001) and coronary artery disease (47.7% vs 27%, P=.021), and had Nocardia isolated exclusively from lung specimens (100% vs 83.1%; P=.003). On CT of the chest, they had frequent airway disease (84.1% vs 51.7%; P<.001). Patients with invasive nocardiosis had significantly (P<.05) more diabetes, chronic kidney disease, solid organ transplant, use of corticosteroids, antirejection drugs, and prophylactic sulfa. They had more fever (25.8% vs 2.3%; P<.001), cutaneous lesions (14.6% vs 0%; P=.005), fatigue (18% vs 0%; P=.001), pulmonary nodules (52.8% vs 27.3%; P=.006), and free-flowing pleural fluid (63.6% vs 29.4%; P=.024). The patterns of nodule distribution were different-diffuse for invasive nocardiosis and peribronchiolar for Nocardia colonization. Conclusion The isolation of Nocardia in sputum from a patient with respiratory symptoms does not equal active infection. Only by combining clinical and chest CT findings, one could better differentiate between invasive nocardiosis and Nocardia colonization.

Abstract
Background Pulmonary autograft reinforcement to prevent dilatation and subsequent neo-aortic valve regurgitation has been reported; however, data on long-term function of the neo-aortic valve after this modified Ross procedure are lacking. Our objective here was to assess long-term outcomes of the modified Ross procedure with autograft reinforcement using the reimplantation technique. Patients The outcomes of 61 consecutive patients managed using the Dacron-conduit reinforced Ross procedure between 2009 and 2021 were reviewed. Most patients had a unicuspid or bicuspid aortic valve (n = 52; 85%), predominant aortic valve regurgitation (n = 42; 77%), and >30 mm dilatation of the ascending aorta (n = 33; 54%). A prior aortic valve procedure was noted in 47 patients (77%) patients, including 38 (62%) with surgical repair and 9 (15%) with balloon dilatation. The pulmonary autograft was reimplanted within a Dacron conduit with a median diameter of 25.6 mm (range, 20-30 mm) using the David valve-sparing aortic root replacement technique. Results All patients survived. The median age at surgery was 16.8 years (range, 6-38 years). Neo-aortic valve replacement was required in 3 patients (4.9%; 95% CI, 0.34%- 12.7%) because of infective endocarditis, left ventricular false aneurysm, and leaflet perforation, respectively; the repeat procedure was done early in 2 of these patients (2 of 61; 3%). Six patients required right ventricular outflow conduit replacement, 5 by surgery and 1 percutaneously. The median duration of follow-up was 90 months (range, 10-124 months). The 5- and 10-year rates of reintervention-free survival were 84.3% (95% CI, 74%-95%) and 81.6% (95% CI, 72%-93%), respectively, and 5-year survival without aortic reintervention was 94.5% (95% CI, 88%-100%), with little change at 10 years. No patients experienced deterioration of initial neo-aortic valve function (ie, regurgitation or stenosis). Conclusions Autograft reinforcement using the reimplantation technique allowed expansion of Ross procedure indications to all patients requiring aortic valve replacement and prevented neo-aortic root dilatation. Failures were uncommon. Long-term follow-up data showed stable neo-aortic valve function.

Abstract
Recent advances in chemotherapy and radiotherapy have led to an increase in the number of long-term survivors of pancreatic cancer. However, this has also increased the number of patients suffering from ectopic varices and bleeding owing to left-sided portal hypertension and thrombocytopenia caused by splenomegaly after pancreaticoduodenectomy combined with resection of the splenic vein. A 65-year-old woman with varices of the elevated jejunum due to left sided portal hypertension after pancreaticoduodenectomy had repeated melena, which started about 1 year before admission. We describe the first reported case of percutaneous transsplenic venous embolization using metallic coils, which successfully achieved hemostasis of refractory bleeding from the elevated jejunal varices after pancreaticoduodenectomy.

Abstract
BACKGROUND A delay in the diagnosis and treatment of an occult femoral neck fracture (OFNF) can negatively affect the subsequent quality of life. We investigated the diagnostic accuracy of ultrasonography for OFNF in patients confirmed with this condition by magnetic resonance imaging (MRI), and compared these results with other clinical findings. METHODS Ninety-four outpatients aged above 70 years with acute hip pain but without radiographic abnormal findings who were suspected of having an occult femoral neck fracture (11 men and 83 women with a mean age of 81.8 ± 6.0 years) were enrolled. Both ultrasonography and MRI were performed in all cases within 24 h. The ultrasonographic distance between the anterior aspect of the femoral neck and the anterior joint capsule (ultrasound joint swelling) was measured. RESULTS By MRI findings, 27 patients were assigned to an occult femoral neck fracture (OFNF) group (1 man, 26 women) and 67 patients to a non-OFNF group (10 men, 57 women). The mean ultrasound joint swelling in both groups was 7.53 ± 1.52 mm and 3.45 ± 0.89 mm, respectively (p = 0.006, 95% CI, 3.58-4.59). A cut-off value of 5.3 mm showed a sensitivity of 0.96 (0.89-0.96) and a specificity of 0.98 (0.92-1.00). CONCLUSIONS Ultrasonography shows very high diagnostic accuracy for occult femoral neck fracture. This modality can thus contribute to initial bed-side examinations for this condition in patients over 70 years with acute hip pain.

Abstract
Background Brenner tumor is a rare epithelial ovarian neoplasm that accounts for 2-3% of all ovarian neoplasms. Herein, we report the first case of thoracic spinal metastasis of recurrent Brenner tumor without local recurrence.Case Description.A 70-year-old female presented with a feeling of abdominal distension. Computed tomography revealed cystic lesions in her bilateral ovaries. Blood examination revealed high CA-125 [74.9 U/ml]. We excised bilateral ovaries, uterus, and omentum. Borderline Brenner tumor was diagnosed [Ki-67 labeling index: 10 %]. Follow-up abdominal echo and CA-125 examination revealed no local recurrence. 26 months later she developed paraplegia. Magnetic resonance imaging revealed tumor in the 5th-9th thoracic vertebra and compression of spinal cord at the 6th thoracic vertebra level. Her paraplegia was progressive. We performed semi-urgent partial resection of tumor and release of spinal cord compression. Spinal metastasis from Brenner tumor was diagnosed [Ki-67 labeling index: 50-60 %]. She received adjuvant radiation of 30 Gy in 10 fractions to the 4th-10th thoracic vertebra. After radiation and rehabilitation, she was discharged home on foot. She received adjuvant radiation and chemotherapy but died 11 months after spinal surgery. An autopsy has not been performed on her, and the cause of death is unknown. Conclusion We report the first case of thoracic metastasis of recurrent Brenner tumor without local recurrence.

Abstract
Objectives Congenital tracheomalacia can be the cause of respiratory failure in young children. Although the indication for surgical treatment has already been discussed vigorously, no clear guidelines about the modality are available. Methods Through a sternotomy approach, a combination of posterior pexy and anterior tracheopexy using a tailored ringed polytetrafluoroethylene prosthesis is performed. Patient demographic characteristics, as well as operative details and postoperative outcomes, are included in the analysis. Results Between 2018 and 2022, 9 children underwent the operation under review. All patients showed severe clinical symptoms of tracheomalacia, which was confirmed on bronchoscopy. The median age was 9 months. There was no operative mortality. Eight patients could be weaned from the ventilator. One patient died because of interstitial lung disease with bronchomalacia and concomitant severe cardiac disease. The longest follow-up now is 4 years, and shows overall excellent clinical results, without any reintervention. Conclusions Surgical treatment of tracheomalacia through a combination of posterior and anterior pexy is feasible, with acceptable short- and midterm results.
