Effect of radical trachelectomy on ovarian reserve: A single-institute prospective study.

AIM: Reduced responses to controlled ovarian stimulation (COS) after radical trachelectomy (RT) have been previously reported. We aimed to assess the effect of RT on ovarian reserve by measuring anti-Müllerian hormone (AMH) levels before and after the procedure in this prospective study. METHODS: We included 12 patients who underwent RT between September 2019 and December 2021 in this study. Serum AMH levels were measured preoperatively, 1 month postoperatively, and 6 months postoperatively. Differences in the AMH levels were assessed using a paired t-test. RESULTS: The median age of the patients was 30.6 years, and the median follow-up time was 30.1 months. AMH levels at 1 and 6 months postoperatively did not show a consistent trend. At 1 month postoperatively, the average AMH level decreased insignificantly but returned to preoperative levels at 6 months. The differences in AMH levels before and after RT were insignificant. CONCLUSION: Our findings indicate that RT did not affect ovarian reserve as measured by AMH levels. However, the relationship between unchanged ovarian reserve and reduced response to COS remains unclear. Further research with larger sample sizes and additional measures of ovarian function is needed to corroborate these results and investigate the long-term effects of RT on ovarian reserve. Understanding these mechanisms will help guide surgical practices and provide patients with valuable information about their reproductive outcomes after RT.

Prevalence of opioid-induced adverse events across opioids commonly used for analgesic treatment in Japan: a multicenter prospective longitudinal study.

PURPOSE: Although opioids have been shown to be effective for cancer pain, opioid-induced adverse events (AEs) are common. To date, little is known about the differences in risks of AEs by opioid type. This study was performed to compare the prevalence of AEs across opioids commonly used for analgesic treatment in Japan. METHODS: This study was conducted as a preplanned secondary analysis of a multicenter prospective longitudinal study of inpatients with cancer pain who received specialized palliative care for cancer pain relief. We assessed daily AEs until termination of follow-up. We rated the severity of AEs based on the Common Terminology Criteria for Adverse Events version 5.0. We computed adjusted odds ratios for each AE (constipation, nausea and vomiting, delirium, and drowsiness) with the following variables: opioid, age, sex, renal dysfunction, and primary cancer site. RESULTS: In total, 465 patients were analyzed. Based on the descriptive analysis, the top four most commonly used opioids were included in the analysis: oxycodone, hydromorphone, fentanyl, and tramadol. With respect to the prevalence of AEs among all analyzed patients, delirium (n = 25, 6.3%) was the most frequent, followed by drowsiness (n = 21, 5.3%), nausea and vomiting (n = 19, 4.8%), and constipation (n = 28, 4.6%). The multivariate logistic analysis showed that no single opioid was identified as a statistically significant independent predictor of any AE. CONCLUSION: There was no significant difference in the prevalence of AEs among oxycodone, fentanyl, hydromorphone, and tramadol, which are commonly used for analgesic treatment in Japan.

Development of novel deep multimodal representation learning-based model for the differentiation of liver tumors on B-mode ultrasound images.

BACKGROUND AND AIM: Recently, multimodal representation learning for images and other information such as numbers or language has gained much attention. The aim of the current study was to analyze the diagnostic performance of deep multimodal representation model-based integration of tumor image, patient background, and blood biomarkers for the differentiation of liver tumors observed using B-mode ultrasonography (US). METHOD: First, we applied supervised learning with a convolutional neural network (CNN) to 972 liver nodules in the training and development sets to develop a predictive model using segmented B-mode tumor images. Additionally, we also applied a deep multimodal representation model to integrate information about patient background or blood biomarkers to B-mode images. We then investigated the performance of the models in an independent test set of 108 liver nodules. RESULTS: Using only the segmented B-mode images, the diagnostic accuracy and area under the curve (AUC) values were 68.52% and 0.721, respectively. As the information about patient background and blood biomarkers was integrated, the diagnostic performance increased in a stepwise manner. The diagnostic accuracy and AUC value of the multimodal DL model (which integrated B-mode tumor image, patient age, sex, aspartate aminotransferase, alanine aminotransferase, platelet count, and albumin data) reached 96.30% and 0.994, respectively. CONCLUSION: Integration of patient background and blood biomarkers in addition to US image using multimodal representation learning outperformed the CNN model using US images. We expect that the deep multimodal representation model could be a feasible and acceptable tool for the definitive diagnosis of liver tumors using B-mode US.

Appropriate referral timing to specialized palliative care service: survey of bereaved families of cancer patients who died in palliative care units.

Few studies have investigated appropriate referral timing of specialized palliative care (SPC) from the perspective of cancer patients' and families' experiences. We aimed to clarify appropriate SPC referral timing for patients with advanced cancer and their families. We used data from a nationwide bereaved family survey in Japan. We sent a questionnaire to 999 bereaved families of cancer patients who died in 164 palliative care units (PCUs) and analyzed the first SPC referral timing and how patients evaluated it. We defined SPC as outpatient or inpatient palliative care service comprising certified palliative care physicians, advanced-practice nurses, and multidisciplinary practitioners. Finally, 51.6% (n = 515) of all responses were analyzed. The SPC referral timing was evaluated as appropriate (26.1%), late or too late (20.2%), early or too early (1.2%), or none of these (52.5%). Of these, 32.3% reported that they were referred to an SPC when diagnosed with advanced or incurable cancer or during anti-cancer treatment, and 62.6% reported they were referred after anti-cancer treatment. Patient-perceived appropriateness of SPC referral timing was associated with their good death process. After excluding "none of these" responses, a significantly higher proportion of respondents who reported being referred to SPC at diagnosis and during anti-cancer treatment evaluated the response timing as appropriate, compared to those who reported being referred after anti-cancer treatment. Appropriate timing for SPC referrals relates to quality of death; findings suggest that appropriate timing is at the time of diagnosis or during anti-cancer treatment.

Augmented activity of the forearm extensor muscles induced by vibratory stimulation of the palm of the hand in individuals with subacute post-stroke hemiplegia.

PRIMARY OBJECTIVE: To examine whether vibration to the palm of the hand induces motor activity in the forearm muscles of individuals with post-stroke and healthy young adults. We hypothesized that the vibration would induce antagonistic muscle activities via the motor cortex. RESEARCH DESIGN: Observational study using the between- and within-subjects mixed design. METHODS AND PROCEDURES: Vibratory stimulation was applied to the palm of the paretic and non-paretic hands in seven post-stroke hemiplegia, and of the right hand in 22 healthy young adults in the eyes-closed and eyes-open conditions. Surface electromyography (sEMG) was recorded from the forearm extensors and flexors and the sEMG amplitudes were analyzed. MAIN OUTCOMES AND RESULTS: The extensor activities were significantly larger than that of the flexors in all hands. Especially, the extensor activities were augmented when the eyes were open in the paretic and non-paretic hands. Moreover, there was greater muscle activity in the non-paretic hand compared with the paretic hand. CONCLUSIONS: These novel findings revealed that vibration to the palm augmented the activity of the antagonistic forearm extensors, especially in the paretic hand, which was induced via top-down cortical modulation. Thus, it can be utilized to improve the impaired forearm extensors in post-stroke rehabilitation.

Visual texture agnosia caused by bilateral posterior cerebral artery stroke: a case study.

A 57-year-old man presented with a bilateral posterior cerebral artery attack and was visually impaired. He had a hard time identifying familiar faces and shades. He also felt that the familiar building looked different, and complained that it was not possible to tell from visual information alone whether the food was cooked or the kimono fabric was soft.We assessed the patient's visual function using real materials and material images and was diagnosed with visual texture agnosia. There are few reports of visual texture agnosia, detailed evaluation is considered important because perceiving texture is important for activities of daily living.

Prognostic model for patients with advanced cancer using a combination of routine blood test values.

PURPOSE: The purpose of this study was to develop a simple prognostic model based on objective indicators alone, i.e., routine blood test data, without using any subjective variables such as patient's symptoms and physician's prediction. METHODS: The subjects of this retrospective study were patients at the palliative care unit of Tohoku University Hospital, Japan. Eligible patients were over 20 years old and had advanced cancer (n = 225). The model for predicting survival was developed based on Cox proportional hazards regression models for univariable and multivariable analyses of 20 items selected from routine blood test data. All the analyses were performed according to the TRIPOD statement ( https://www.tripod-statement.org/ ). RESULTS: The univariable and multivariable regression analyses identified total bilirubin, creatinine, urea/creatinine ratio, aspartate aminotransferase, albumin, total leukocyte count, differential lymphocyte count, and platelet/lymphocyte ratio as significant risk factors for mortality. Based on the hazard ratios, the area under the curve for the new risk model was 0.87 for accuracy, 0.83 for sensitivity, and 0.74 for specificity. Diagnostic accuracy was higher than provided by the Palliative Prognostic Score and the Palliative Prognostic Index. The Kaplan-Meier analysis demonstrated a survival significance of classifying patients according to their score into low-, medium-, and high-mortality risk groups having median survival times of 67 days, 34 days, and 11 days, respectively (p < 0.001). CONCLUSIONS: We developed a simple and accurate prognostic model for predicting the survival of patients with advanced cancer based on routine blood test values alone that may be useful for appropriate advanced care planning in a palliative care setting.

Effects of parenteral nutrition and hydration on survival in advanced cancer patients with malignant bowel obstruction: secondary analysis of a multicenter prospective cohort study.

PURPOSE: The benefits of parenteral nutrition and hydration (PNH) in patients with advanced cancer remain unknown. Therefore, we conducted a prospective multicenter cohort study to assess the effects of PNH on survival in patients with malignant bowel obstruction (MBO). METHODS: The present study was a secondary analysis. Data on primary nutritional administration routes during the first week of admission to palliative care units, i.e., parenteral nutrition and parenteral hydration, were obtained. Data on the averaged calorie sufficiency rate/total calorie intake (75% ≤ or 750 kcal/day ≤ , 50-75% or 500-750 kcal/day, 25-50% or 250-500 kcal/day, and < 25% or < 250 kcal/day) were also obtained. Participants with MBO were included and divided into two groups: PNH-high (25% ≤ or 250 kcal/day ≤) and PNH-low (< 25% or < 250 kcal/day). We performed time-to-event analyses using the Kaplan-Meier method, log-rank test, and univariate and multivariate Cox regression analyses. RESULTS: Patients were divided into the PNH-high (n = 68) and PNH-low (n = 76) groups. A significant difference was observed in survival rates between the two groups (log-rank P < 0.001). Median survival times were 35.5 (95% CI 27-44) and 17.5 (95% CI 13-21) days, respectively. In the multivariate-adjusted model, a significantly lower risk of mortality was observed in Cox's proportional hazard model in the PNH-high group (HR 0.55 (95% CI 0.36-0.83), P = 0.005) than in the PNH-low group. CONCLUSION: The present results indicated the beneficial effects of PNH for prolonging survival in advanced cancer patients with MBO in palliative care units.

Identification of liver fibrosis using the hepatic vein waveform in patients with Fontan circulation.

AIM: Liver fibrosis caused by congestive hepatopathy has emerged as an important complication after Fontan procedure. We evaluated the utility of the hepatic vein (HV) waveform using Doppler ultrasound for identification of liver fibrosis in Fontan patients. METHODS: We investigated the HV waveforms in 41 Fontan patients and assessed correlations with clinical parameters, liver fibrosis markers, and hemodynamic data. RESULTS: Based on our preliminary analysis of 64 adult patients with chronic liver disease who underwent liver biopsy, we classified HV waveforms into five types with reference to the degree of flattening (from type 1, normal triphasic waveform; to type 5, a monophasic waveform indicating cirrhosis), and confirmed a significant correlation between waveform pattern and fibrosis stage. Notably, we detected HV waveforms in all of the Fontan patients and classified them into five types. The HV waveform pattern positively correlated with γ-glutamyl transferase and hyaluronic acid levels, and negatively correlated with albumin level and platelet count, but did not correlate with central venous pressure or brain natriuretic peptide level, suggesting that HV waveform could reflect pathophysiological changes in the liver without being affected by hepatic congestion. The highest area under the receiver operating characteristic curve of the HV waveform for detecting advanced liver fibrosis, as defined by ultrasonic findings and clinical features, was 0.829 (81.8% sensitivity, 73.3% specificity), which was higher than that of other non-invasive fibrosis markers. CONCLUSIONS: Hepatic vein waveforms change in accordance with liver fibrosis progression in Fontan patients, and can be a useful indicator of liver fibrosis after the Fontan procedure.

A New Membrane Protein Sbg1 Links the Contractile Ring Apparatus and Septum Synthesis Machinery in Fission Yeast.

Cytokinesis in many organisms requires a plasma membrane anchored actomyosin ring, whose contraction facilitates cell division. In yeast and fungi, actomyosin ring constriction is also coordinated with division septum assembly. How the actomyosin ring interacts with the plasma membrane and the plasma membrane-localized septum synthesizing machinery remains poorly understood. In Schizosaccharomyces pombe, an attractive model organism to study cytokinesis, the ß-1,3-glucan synthase Cps1p / Bgs1p, an integral membrane protein, localizes to the plasma membrane overlying the actomyosin ring and is required for primary septum synthesis. Through a high-dosage suppressor screen we identified an essential gene, sbg1+ (suppressor of beta glucan synthase 1), which suppressed the colony formation defect of Bgs1-defective cps1-191 mutant at higher temperatures. Sbg1p, an integral membrane protein, localizes to the cell ends and to the division site. Sbg1p and Bgs1p physically interact and are dependent on each other to localize to the division site. Loss of Sbg1p results in an unstable actomyosin ring that unravels and slides, leading to an inability to deposit a single contiguous division septum and an important reduction of the ß-1,3-glucan proportion in the cell wall, coincident with that observed in the cps1-191 mutant. Sbg1p shows genetic and / or physical interaction with Rga7p, Imp2p, Cdc15p, and Pxl1p, proteins known to be required for actomyosin ring integrity and efficient septum synthesis. This study establishes Sbg1p as a key member of a group of proteins that link the plasma membrane, the actomyosin ring, and the division septum assembly machinery in fission yeast.

Disappearance of perihepatic lymph node enlargement after hepatitis C viral eradication with direct-acting antivirals.

Perihepatic lymph node enlargement (PLNE) which has been shown to be negatively associated with hepatocellular carcinoma (HCC) occurrence is frequently observed in chronic liver disease; however, changes in the state of perihepatic lymph nodes after eradication of hepatitis C virus (HCV) have not been investigated yet. We aimed to evaluate this issue. We enrolled 472 patients with chronic HCV infection who achieved viral eradication with direct-acting antivirals (DAA). We investigated whether the status of perihepatic lymph nodes changed before and after HCV eradication (primary endpoint). We also evaluated the association between PLNE and clinical findings such as liver fibrosis or hepatocellular injury before HCV eradication (secondary endpoint). Perihepatic lymph node enlargement was detected in 164 of 472 (34.7%) patients before DAA treatment. Surprisingly, disappearance of PLNE was observed in 23.8% (39 patients) of all PLNE-positive patients after eradication of HCV. Disappearance of PLNE was not associated with baseline clinical parameters or changing rates of clinical findings before and after DAA treatment. At baseline, presence of PLNE was significantly associated with a lower serum HCV-RNA level (P = .03), a higher serum AST level (P = .004) and a higher ALT level (P < .001) after adjustment for sex and age. In conclusion, PLNEs became undetectable after DAA treatment in 23.8% of PLNE-positive patients. Further study with a longer follow-up period is needed to clarify the clinical importance of this phenomenon especially in relationship with the risk of HCC development.

Cooperation between Paxillin-like Protein Pxl1 and Glucan Synthase Bgs1 Is Essential for Actomyosin Ring Stability and Septum Formation in Fission Yeast.

In fungal cells cytokinesis requires coordinated closure of a contractile actomyosin ring (CAR) and synthesis of a special cell wall structure known as the division septum. Many CAR proteins have been identified and characterized, but how these molecules interact with the septum synthesis enzymes to form the septum remains unclear. Our genetic study using fission yeast shows that cooperation between the paxillin homolog Pxl1, required for ring integrity, and Bgs1, the enzyme responsible for linear ß(1,3)glucan synthesis and primary septum formation, is required for stable anchorage of the CAR to the plasma membrane before septation onset, and for cleavage furrow formation. Thus, lack of Pxl1 in combination with Bgs1 depletion, causes failure of ring contraction and lateral cell wall overgrowth towards the cell lumen without septum formation. We also describe here that Pxl1 concentration at the CAR increases during cytokinesis and that this increase depends on the SH3 domain of the F-BAR protein Cdc15. In consequence, Bgs1 depletion in cells carrying a cdc15ΔSH3 allele causes ring disassembly and septation blockage, as it does in cells lacking Pxl1. On the other hand, the absence of Pxl1 is lethal when Cdc15 function is affected, generating a large sliding of the CAR with deposition of septum wall material along the cell cortex, and suggesting additional functions for both Pxl1 and Cdc15 proteins. In conclusion, our findings indicate that CAR anchorage to the plasma membrane through Cdc15 and Pxl1, and concomitant Bgs1 activity, are necessary for CAR maintenance and septum formation in fission yeast.

Role of extracellular vesicles in the interaction between epithelial and mesenchymal cells during oviductal ciliogenesis.

Extracellular vesicles (EVs) have been shown to transport miRNA, mRNA and protein, suggesting that they are new communication mediators. Diffusible mesenchymal factors determine the fate of Mullerian epithelial cells into oviductal ciliated cells. In the present study, we investigated whether EVs mediate the communication in the epithelial-mesenchymal interaction during oviductal ciliogenesis. EVs were isolated from cells of oviductal mesenchymal cell line (S1 cells) and characterized by TEM and expression of exosomal marker CD81. CD81 protein was also detected in oviductal mesenchyme, suggesting that CD81-expressing exosomes may be secreted from oviductal mesenchyme, as well as S1 cells. ß-actin, Gapdh and Vimentin mRNAs and miRNAs were detected in the exosomes. mRNA in S1 cells was able to be transported into cells of Mullerian epithelial cell line (E1 cells) via the exosomes. The effects of exosomes derived from S1 cells on ciliogenesis of E1 cells were analyzed by in vitro models. Culture with exosomes increased the number of ciliated cells in E1 cells. These results suggest that exosomes derived from mesenchymal cells modulate the oviductal ciliogenesis and open new avenues for developmental study of EVs.

Enhancement of bactericidal activity against group B streptococci with reduced penicillin susceptibility by uptake of gentamicin into cells resulting from combination with ß-lactam antibiotics.

Combined effects of penicillin (PEN) and gentamicin (GM) against Streptococcus agalactiae, i.e. group B streptococci (GBS), are known to occur, but synergy has not been examined in strains with reduced PEN susceptibility, usually called PEN-resistant GBS (PRGBS). We therefore studied combined effects of ß-lactam antibiotics and GM in cultures of 3 PRGBS strains belonging to serotype Ia or III that were isolated from Japanese adults with invasive infections. Killing kinetics were determined at 2-h intervals from 0 to 6 h after exposure to ampicillin (AMP) or cefotaxime (CTX) combined with GM. Concentrations of GM in bacterial cells were measured by liquid chromatography-tandem mass spectrometry. Morphologic changes after exposure to agents were observed by transmission electron microscopy. Combining AMP or CTX with GM synergistically increased bactericidal activity against PRGBS beyond that of either ß-lactam alone. GM concentrations in bacterial cells increased 5- to 8-fold when GM was combined with AMP or CTX. Electron microscopically, bacterial cells showed aggregates of strands and ribosomal damage most likely reflecting enhanced GM uptake into bacterial cells. This uptake appeared to result from cell wall damage caused by ß-lactam antibiotics. This study suggests that combining ß-lactam antibiotics with GM might be useful against severe PRGBS infection.

Potential associations between perihepatic lymph node enlargement and liver fibrosis, hepatocellular injury or hepatocarcinogenesis in chronic hepatitis B virus infection.

AIM: Although perihepatic lymph node enlargement (PLNE) is frequently observed in chronic liver disease, little is known about PLNE in chronic hepatitis B virus (HBV) infection. We aimed to evaluate this issue. METHODS: We originally enrolled a consecutive 502 patients with chronic HBV infection. Among them, 288 patients without history of interferon-based or nucleoside analog treatment and hepatocellular carcinoma (HCC) were primarily analyzed. RESULTS: PLNE was detected in 27 of 288 (9.4%) patients, which was fewer than that in chronic hepatitis C patients but more than that in subjects undertaking a general health examination as previously reported. The presence of PLNE was significantly associated with a higher probability of having an aspartate aminotransferase (AST) platelet ratio index of more than 1.5 (11.1% vs 1.5%, P = 0.01), a higher AST level (38.0 vs 26.8 U/L, P = 0.001), a higher alanine aminotransferase level (50.1 vs 28.0 U/L, P < 0.0001), and a lower platelet count (18.6 vs 20.6 × 10(4) /µL, P = 0.048) after adjustment for sex and age. However, in our original sample (n = 502), PLNE was observed in 1.4% of the patients with HCC and/or its history whereas 9.2% of the patients without HCC, and the proportion was significantly lower in patients with HCC and/or its history (P = 0.03). CONCLUSION: PLNE was associated with liver fibrosis and hepatocellular injury, but was negatively associated with HCC in chronic HBV infection.

A Case of Mirror-Image Crossed Thalamic Aphasia With Jargon Agraphia.

In right-handed individuals, aphasia resulting from right hemisphere damage is termed crossed aphasia and has a very low occurrence rate. Additionally, aphasia due to thalamic lesions often involves hemorrhage, with infarction cases less frequently reported. We present the case of an 81-year-old right-handed female who developed aphasia due to a right thalamic infarction. She exhibited characteristics typical of thalamic aphasia observed in left thalamic lesions. Furthermore, jargon agraphia manifested during writing tasks. This may suggest disinhibition of the left hemisphere writing motor memory by the right hemisphere language function.

Hashimoto Encephalopathy and Thyroid Storm by Diabetic Ketoacidosis and Acute Pancreatitis: A Case Report.

Hashimoto encephalopathy (HE) is a rare condition related to autoimmune origin characterized by high titers of antithyroid antibodies. Steroids are effective for treatment of HE, suggesting the autoimmunity as an underlying mechanism. In addition, anti-NH2-terminal of α-enolase antibodies (anti-NAE antibodies) is useful for diagnosis of HE. This report describes a 69-year-old woman developing both HE and thyroid storm (TS), following diabetic ketoacidosis (DKA) and acute pancreatitis. She had a history of Basedow's disease and uncontrolled type 2 diabetes mellitus, and her serum hemoglobin A1c was 10%. She complained of nausea and visited our hospital. She was diagnosed with DKA and acute pancreatitis. After admission, she went into cardiopulmonary arrest and she was diagnosed with TS after resuscitation. In addition, blood test collected during acute phase of TS revealed positive for not only anti-thyroid peroxidase (TPO) antibodies, thyroid stimulating hormone receptor antibodies and thyroid stimulating antibodies, but also anti-NAE antibodies. She was treated with intravenous steroids, potassium iodide and thiamazole under respirator and recovered sufficiently to do daily activities of life. We should keep in mind that there might be cases of HE in cases of TS presenting with central nervous system symptoms.

Pure Motor Isolated Finger Palsy by Cerebral Infarction: Tips for Diagnosis by Neurological Examination.

There are various causes of unilateral finger palsy. Its potential etiologies include peripheral neuropathy, carpal tunnel syndrome, and nerve root disorder due to myelopathy. In addition to them, similar paralysis has been reported in localized lesions of the cerebrum, classically referred to as pseudoperipheral palsy. In this report, we describe a case of an 80-year-old man who developed sudden clumsiness of the right fingers. Neurological examination showed muscle weakness mainly in the 1st and 2nd fingers (Medical Research Council grade 1-4) and normal reflexes in the extremities. The affected muscles were innervated by the median nerve, ulnar nerve, and radial nerve, and their nerve root levels ranged from C6 to T1. All the Phalen's, Tinel's, and flick signs were negative. Diffusion-weighted brain magnetic resonance imaging showed hyperintensity limited in the precentral knob on the left precentral gyrus. The etiology was diagnosed as cardiogenic embolism due to atrial fibrillation. In this report, we provide key findings for diagnosing pure motor isolated finger palsy by cerebral infarction through neurological examination.

A Case of Autoimmune Polyendocrine Syndrome Type 3B and Peripheral Neuropathy Due to Thiamine Deficiency.

Autoimmune polyendocrine syndrome (APS) type 3B is characterized by presence of autoimmune thyroid disease, chronic atrophic gastritis and pernicious anemia. In this report, we present a rare case of APS type 3B with neuropathy by thiamine deficiency. A 65-year-old man had a history with hypothyroidism, gastritis, gastrectomy for gastric cancer and subacute combined degeneration of the spinal cord. Patient developed polyneuropathy with not mecobalamin but thiamine deficiency. Serum anti-thyroglobin (TG), anti-thyroid peroxidase (TPO), and anti-gastric parietal cell antibodies were positive. He was treated with thiamine supplementation and improved muscle weakness, sensory impairment and gait disturbance. Classically, it is reported gastric cancer related to hypothyroidism. Additionally, thiamine deficiency can be caused by gastrectomy. Here, his thiamine deficiency was related to APS type 3B, leading to polyneuropathy.

Dural Arteriovenous Fistula in Neuro-Behçet's Disease: Association or Chance?

Behçet's disease (BD) is a multisystemic vasculitis disorder. Neuro-Behçet's disease (NBD) is a set of neurologic symptoms imputable to an underlying Behçet vasculitis. Among the wide range of vascular abnormalities secondary to BD, a dural arteriovenous fistula (dAVF) is not classically described. Whether a dAVF is associated with BD or dAVF is a chance occurrence is still a matter of debate. Herein, we describe an NBD case of a 48-year-old male, presenting with headache and fever, where a dAVF was seen on imaging. He was treated with prednisolone and colchicine, followed by the surgical resection for dAVF. Then, we discuss the possible association between BD and dAVF based on the latest literature.
