BACKGROUND: Tandem spinal stenosis (TSS) is a condition characterized by the narrowing of the spinal canal in multiple segments of the spine. Predominantly observed in the cervical and lumbar regions, TSS also manifests in the conjunction of the cervical and thoracic spine. The simultaneous occurrence of cervical and thoracic spinal stenosis engenders intricate symptoms, potentially leading to missed and delayed diagnosis. Furthermore, the presence of tandem cervical and thoracic stenosis (TCTS) introduces a notable impact on the decision-making calculus of surgeons when contemplating either one-staged or two-staged surgery. Currently, there is no agreed-upon strategy for surgical intervention of TCTS in the literature.
METHODS: Medical databases in English (Pubmed, Web of Science, Embase, the Cochrane Database of Systematic Reviews) and Chinese (CNKI, Wanfang Data, VIP CMJD) were searched using Medical Subject Heading queries for the terms \"tandem cervical and thoracic stenosis\", \"cervical stenosis AND thoracic stenosis\", \"tandem spinal stenosis\" and \"concomitant spinal stenosis\" from January 1980 to March 2023. We included studies involving adult individuals with TCTS. Articles exclusively focused on disorders within a single spine region or devoid of any mention of spinal disorders were excluded.
RESULTS: Initially, a total of 1625 literatures underwent consideration for inclusion in the study. Following the elimination of the duplicates through the utilization of EndNote, and a meticulous screening process involving scrutiny of abstracts and full-texts, 23 clinical studies met the predefined inclusion criteria. Of these, 2 studies solely focused on missed diagnosis, 19 studies exclusively discussed surgical strategy for TCTS, and 2 articles evaluated both surgical strategy and missed diagnosis.
CONCLUSIONS: Our study revealed a missed diagnosis rate of 7.2% in TCTS, with the thoracic stenosis emerging as the predominant area susceptible to oversight. Therefore, the meticulous identification of TCTS assumes paramount significance as the inaugural step in its effective management. While both one-staged and two-staged surgeries have exhibited efficacy in addressing TCTS, the selection of the optimal surgical plan should be contingent upon the individualized circumstances of the patients.

BACKGROUND: The WHO presented the initiative: \"Global elimination of congenital syphilis (CS): rationale and strategies for action\". It establishes that CS is a preventable disease that can be eliminated.
OBJECTIVE: To estimate the proportion of missed opportunities for prevention (MOP) of (CS).
METHODS: Cross-sectional study. We studied women with children with confirmed diagnosis of CS (NOM-039-SSA2-2002) in the Mexican Social Security Institute in Jalisco from 01/01/2016 to 08/01/2022. The clinical records of the mother, the newborn and the epidemiological study (ES) were reviewed. Each case was classified into one of the MOP categories.
RESULTS: 52 cases were reported: 46.2 % (n = 24) were ruled out, 34.6 % (n = 18) confirmed, 15.4 % (n = 8) unknown and 3.8 % (n = 2) probable cases. The HIV test was performed in 61.1 % (n = 11) and syphilis in 72.2 % (n = 13) of the mothers. The MOP in 27.8 % (n = 5) was inadequate treatment or omission of maternal treatment despite a timely diagnosis of syphilis. Treatment was inadequate in 63.6 % (n = 7) of the women who received it.
CONCLUSIONS: The classification of MOP identifies gaps in CS prevention and can guide stakeholders, policy makers and public health prevention programs to reduce the incidence of CS.
BACKGROUND: La Organización Mundial de la Salud estableció que la sífilis congénita es una enfermedad prevenible que puede eliminarse.
OBJECTIVE: Estimar la proporción de oportunidades perdidas en la prevención (OPP) de la sífilis congénita.
UNASSIGNED: Estudio transversal descriptivo. Se eligieron mujeres en cuyos hijos recién nacidos se identificó sífilis congénita entre 2016 y 2022. Se revisaron los expedientes clínicos de la madre, el recién nacido y el estudio epidemiológico. Cada caso se clasificó en una de las categorías de las OPP.
RESULTS: Se notificaron 52 casos: 46.2 % (n = 24) fue descartado, 34.6 % (n = 18) confirmado, 15.4 % (n = 8) desconocido y 3.8 % (n = 2) probable. Las pruebas para identificar infección por VIH y sífilis se realizaron en 61.1 % (n = 11) y 72.2 % de las madres (n = 13). La OPP en 27.8 % (n = 5) consistió en el tratamiento inadecuado u omisión de tratamiento materno a pesar de diagnóstico oportuno de la sífilis. De quienes recibieron tratamiento, en 63.6 % fue inadecuado (n = 7).
UNASSIGNED: La clasificación de OPP de sífilis congénita permite identificar brechas en la prevención y dirigir intervenciones de salud pública hacia las principales causas para reducir la incidencia.

UNASSIGNED: The aim of this study was to determine the clinical characteristics and outcome of patients with aortic dissection (AD) who present with an initial manifestation of cerebral infarction.
UNASSIGNED: We retrospectively analyzed patients who were diagnosed with AD and admitted to the emergency department from May 1, 2017 to May 1, 2022. Data was collected for variables including age, sex, clinical manifestation, past medical history, and laboratory test results.
UNASSIGNED: Twenty-five patients (2.61%, 22 type A and 3 type B) showed cerebral infarction as the primary presentation for acute AD, while another 933 AD patients (471 type A and 462 type B) who presented with other symptoms served as the control group. Eighteen of the 25 patients (72%) were initially diagnosed with stroke, and the diagnosis of AD was missed. However, patients with a missed diagnosis of AD did not have significantly different mortality to those in whom AD was diagnosed (chi-square test, p > 0.9999). Patients with cerebral infarction as the first presentation had a higher incidence of type A AD than the control patients (p = 0.0002), while their mortality rate was also higher than the control group of AD patients (p < 0.0001). Furthermore, patients with cerebral infarction as the first presentation were more likely to have multiple organ dysfunction.
UNASSIGNED: AD with an initial presentation of cerebral infarction is a rare condition with high mortality. However, the initial failure to diagnose AD does not further increase patient mortality.

Long-acting intrauterine contraceptives such as intrauterine devices (IUD) are popular due to their high rates of long-term efficacy, ease of use, and reversibility. Though rare, these devices can incur complications such as uterine perforation. Signs and symptoms are often vague abdominal and pelvic pain, and patients rarely present with a surgical emergency. This uterine perforation can happen immediately upon IUD placement or in a delayed manner. This case details an example of an IUD uterine perforation with abdominal migration two years after placement. The patient\'s history is complicated by the unique fact that she became pregnant and carried her pregnancy to a term vaginal delivery after the IUD had been placed. Her pregnancy led healthcare providers from previous encounters to believe that the IUD had been spontaneously expelled. The IUD was identified in the patient\'s left lower abdominal cavity via computed tomography (CT) and was surgically removed uneventfully.

BACKGROUND Inferior vena cava (IVC) injury is a potentially fatal injury with a high mortality rate of 34-70%. In cases in which the patient\'s condition is stable, diagnosis by computed tomography (CT) is the criterion standard. Findings on CT include retroperitoneal hematoma around the IVC, extravasation of contrast medium, and abnormal morphology of the IVC. We report a case of an IVC injury that could not be diagnosed by preoperative CT examination and could not be immediately detected during laparotomy. CASE REPORT A 73-year-old woman had stabbed herself in the neck and abdomen at home using a knife. When she arrived at our hospital, we found a stab wound several centimeters long on her abdomen and a cut approximately 15 cm long on her neck. We activated the massive transfusion protocol because she was in a condition of hemorrhagic shock. After blood transfusion and blood pressure stabilization, contrast-enhanced computed tomography (CT) revealed a small amount of fluid in the abdominal cavity. An otorhinolaryngologist performed successful drainage and hemostasis, and a laparotomy was performed. Gastric injury and mesentery injury of the transverse colon were identified and repaired with sutures. Subsequent search of the retroperitoneum revealed massive bleeding from an injury to the inferior vena cava (IVC). The IVC was repaired. Postoperative progress was good, and she was discharged from the hospital 65 days after her injuries. CONCLUSIONS We experienced a case of penetrating IVC injury, which is a rare trauma. Occult IVC injury may escape detection by preoperative CT examination or during laparotomy.

The ENDOANGEL (EN) computer-assisted detection technique has emerged as a promising tool for enhancing the detection rate of colorectal adenomas during colonoscopies. However, its efficacy in identifying missed adenomas during subsequent colonoscopies remains unclear. Thus, we herein aimed to compare the adenoma miss rate (AMR) between EN-assisted and standard colonoscopies. Data from patients who underwent a second colonoscopy (EN-assisted or standard) within 6 months between September 2022 and May 2023 were analyzed. The EN-assisted group exhibited a significantly higher AMR (24.3% vs 11.9%, P = .005) than the standard group. After adjusting for potential confounders, multivariable analysis revealed that the EN-assisted group had a better ability to detect missed adenomas than the standard group (odds ratio = 2.89; 95% confidence interval = 1.14-7.80, P = .029). These findings suggest that EN-assisted colonoscopy represents a valuable advancement in improving AMR compared with standard colonoscopy. The integration of EN-assisted colonoscopy into routine clinical practice may offer significant benefits to patients requiring hospital resection of lesions following adenoma detection during their first colonoscopy.

BACKGROUND: Non-A non-B (NANB) aortic dissections are uncommon and frequently unrecognized diseases. However, their proper identification is crucial given the unpredictable behavior of the dissected aorta with potential mortality and increased morbidity. We investigate the accuracy of radiological computed tomography angiography (CTA) reports in the diagnosis of acute NANB and the risk related to delayed recognition or misdiagnosis.
METHODS: The pretreatment contrast CTA of all consecutive patients admitted with acute aortic dissection (AAD) in a University Hospital in London (UK) between January 2017 and May 2023 were reviewed to retrospectively verify the accuracy of CTA reports in the diagnosis of NANB AAD (B1-2D The risk related to the delayed diagnosis (morbidity, mortality, and hospital readmissions) were evaluated as secondary outcomes. The study was conducted according to the Strengthening the Reporting of Observational Studies in Epidemiology guidelines.
RESULTS: Overall, 588 aortic CTAs were reviewed for a total of n = 393 (66.8%) type A AADs, n = 171 (29%) type B AADs and n = 25 (4.3%) NANB AADs (n = 16, 64% men, mean age 60.56, standard deviation ± 14.6 years). While no case of misdiagnosis was identified in Type A or B AAD groups, in NANBs only about a third of cases (n = 9, 36%) were immediately indicated as \"NANB\" (n = 2, 8%) or \"B with retrograde extension into the arch\" (n = 7, 28%), n = 8 cases (32%) were described generically as \"arch dissections\" (n = 6, 24%) or \"type A and B\" AAD (n = 2, 8%). The remaining 32% of patients received a diagnosis that did not include mention of the arch, as n = 6 (24%) cases were reported to be \"type A″ and n = 2 (8%) to be \"type B″ AADs. Despite the heterogeneity of terms used to describe NANB AAD, no case of cardiac tamponade, new onset malperfusion nor neurological complications were reported, and no sudden death nor home-discharge and readmission while waiting for the proper diagnosis.
CONCLUSIONS: The heterogeneity of terms used to describe NANB aortic dissection highlights the need for increased awareness, adoption of in guideline based classification systems, and further education to better understand and correctly address this challenging entity, minimizing misdiagnosis in ambiguous or difficult cases.

Joint hypermobility syndromes, particularly chronic pain associated with this condition, including Hypermobile Ehlers-Danlos Syndrome (hEDS) and Hypermobility Spectrum Disorders (HSD), present diagnostic challenges due to their multifactorial origins and remain poorly understood from biomechanical and genomic-molecular perspectives. Recent diagnostic guidelines have differentiated hEDS, HSD, and benign joint hypermobility, providing a more objective diagnostic framework. However, incorrect diagnoses and underdiagnoses persist, leading to prolonged journeys for affected individuals. Musculoskeletal manifestations, chronic pain, dysautonomia, and gastrointestinal symptoms illustrate the multifactorial impact of these conditions, affecting both the physical and emotional well-being of affected individuals. Infrared thermography (IRT) emerges as a promising tool for joint assessment, especially in detecting inflammatory processes. Thermal distribution patterns offer valuable insights into joint dysfunctions, although the direct correlation between pain and inflammation remains challenging. The prevalence of neuropathies among hypermobile individuals accentuates the discordance between pain perception and thermographic findings, further complicating diagnosis and management. Despite its potential, the clinical integration of IRT faces challenges, with conflicting evidence hindering its adoption. However, studies demonstrate objective temperature disparities between healthy and diseased joints, especially under dynamic thermography, suggesting its potential utility in clinical practice. Future research focused on refining diagnostic criteria and elucidating the underlying mechanisms of hypermobility syndromes will be essential to improve diagnostic accuracy and enhance patient care in this complex and multidimensional context.

Tuberculosis (TB) is the leading infectious cause of mortality in sub-Saharan Africa (SSA); the high prevalence of TB in this region is due to human immunodeficiency virus (HIV)-coinfection. Despite the advent of modalities to diagnose TB, undiagnosed TB-related deaths among HIV-infected patients remain significantly high. This systematic review aims at characterizing missed TB cases from postmortem studies. This review informs on the burden of TB missed diagnosis and highlights the need of improving TB case-finding strategies, especially among the high-risk groups and early TB therapy initiation to keeping in with the World Health Organization\'s end TB strategy. We searched PubMed, Cochrane, Web of Science, and African journals online for studies that looked into missed TB cases following postmortem using the following key terms: postmortem, TB diagnosis, and HIV; we included cross-sectional and cohorts from 1980 in the English language that were carried out in SSA among adults\' population. Authors used the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines for reporting, the quality of the included studies was assessed using the Newcastle-Ottawa Scale for observational studies, and STATA 17.0 software was used for analysis. This study was registered in the International Prospective Register of Systematic Reviews with registration number CRD42024507515. The combined prevalence of postmortem missed TB diagnosis among the 6025 participants was 27.13% (95% confidence interval [CI] =14.52-41.89), with a high level of heterogeneity at 98.65% (P < 0.001). The prevalence varied significantly across the included studies, ranging from 1.21% (95% CI = 0.93-1.59) in the general population to 66.67% (95% CI = 50.98-79.37) in people living with HIV (PLWHIV). This current literature suggests that SSA is a region with a high prevalence of missed TB cases but with significant variations between countries. In addition, this study confirms a high number of missed TB infections within the PLWHIV. These results highlight the immediate need for targeted screening and diagnosis strategies and relevant policies.

BACKGROUND: Missed early gastric cancer (MEGC) is prevalent during esophagogastroduodenoscopy (EGD), which is the first-line recommended strategy for detecting early gastric cancer (EGC). Hence, we explored the risk factors for MEGC and different types of MEGC, based on the endoscopic resected population.
METHODS: This retrospective, case-control study was conducted at Nanjing Drum Tower Hospital (NJDTH). We included patients who were diagnosed with EGC during screening EGD, underwent endoscopic resection, and were confirmed by postoperative pathology at the NJDTH from January 2014 to December 2021, and classified them into different types according to the different root causes of misses. Univariable, multivariable, subgroup and propensity score analyses were used to explore the risk factors for MEGC and different types of MEGC.
RESULTS: A total of 447 patients, comprising 345 with initially detected early gastric cancer (IDEGC) and 102 with MEGC, were included in this study. Larger size (≥ 1 cm) (OR 0.45, 95% CI 0.27-0.74, P = 0.002) and invasion depth of submucosa (OR 0.26, 95% CI 0.10-0.69, P = 0.007) were negatively associated with MEGC. Use of sedation (OR 0.32, 95% CI 0.20-0.52, P < 0.001) and longer observation time (OR 0.60, 95% CI 0.37-0.96, P = 0.034) exhibited protective effect on MEGC.
CONCLUSIONS: Smaller and more superficial EGC lesions are more susceptible to misdiagnosis. The use of sedation and prolonged observation time during EGD could help reduce the occurrence of MEGC.
