RESUMO

A 4-year-old girl was admitted to our hospital because of precocious puberty. Radiologic findings revealed a fist-sized solid tumor in the left ovary without ascites, peritoneal dissemination, and distant metastasis. The patient underwent left salpingo-oophorectomy without spillage. The size of the excised tumor was 10.0×9.0×4.8 cm. On pathologic examination, the tumor was diagnosed as an ovarian steroid cell tumor, not otherwise specified. In the present case, although the diameter of the tumor (>7 cm) and three mitoses per 10 high-power fields represented some potential for malignancy, we opted for careful observation without chemotherapy as the tumor was of clinical stage Ia.

RESUMO

PURPOSE: This study aimed to investigate the incidence and clinical factors associated with undescended testes (UDT) in patients with congenital diaphragmatic hernia (CDH). METHODS: We retrospectively reviewed the incidence of UDT in male neonates admitted to our institution and underwent surgery for CDH between January 2006 and December 2022. Patients were divided into two groups based on the presence or absence of UDT, and risk factors for UDT were compared between the two groups. RESULTS: Among the 66 male neonates with CDH, 16 (24.2%) developed UDT. Patients with UDT had a significantly smaller gestational age (p = 0.026), lower birth weight (p = 0.042), and lower Apgar score at 1 min (p = 0.016) than those without UDT. They had a significantly higher incidence of large diaphragmatic defects (p = 0.005), received more patch closures (p = 0.020), had a longer mechanical ventilation period (p = 0.034), and longer hospital stay (p = 0.028). Multiple logistic regression analysis revealed that large diaphragmatic defect was an independent risk factor for UDT (adjusted odds ratio of 3.87). CONCLUSION: CDH and UDT are strongly correlated. In patients with CDH, the incidence of UDT was related not only to patients' prematurity but also to the large diaphragmatic defect. Large diaphragmatic defect is an independent risk factor for UDT in patients with CDH.

RESUMO

PURPOSE: This study aimed to evaluate the feasibility and safety of laparoscopic resection of abdominal neuroblastoma by comparing operative and long-term oncologic outcomes between open and laparoscopic surgeries. METHODS: This single-center retrospective study included patients who underwent laparoscopic tumor resection, between January 2000 and June 2021, with a maximum tumor diameter of ≤ 60 mm and without image-defined risk factors (IDRFs) at surgery. Data from 35 abdominal neuroblastoma resections were reviewed and compared between the laparotomy and laparoscopic groups. RESULTS: Nineteen patients underwent laparotomy and 16 had laparoscopic tumor resection. All laparoscopic surgeries achieved complete resection without conversion to open surgery. Median blood loss was significantly lower in the laparoscopic group (0.6 mL/kg) than in the laparotomy group (8.4 mL/kg) (P < 0.0001). There were two locoregional recurrences in the laparoscopic group and two metastatic recurrences in the laparotomy group. Five-year overall survival was 93.8% in both groups. CONCLUSION: Laparoscopic resection of abdominal neuroblastomas in children is a feasible and safe procedure for tumors ≤ 60 mm in diameter with no IDRFs at surgery, with long-term outcomes equivalent to laparotomy.

RESUMO

PURPOSE: To identify risk factors for delayed oral nutrition in infants with a congenital diaphragmatic hernia (CDH) and its impact on developmental delay at 18 months of age. METHODS: This retrospective single-center cohort study compared the clinical parameters in patients with isolated CDH born and treated at our hospital between 2006 and 2020. We evaluated clinical features significantly related to delayed oral nutrition (defined as taking ≥ 30 days from weaning from mechanical ventilation to weaning from tube feeding). RESULTS: Twenty-six of the 80 cases had delayed oral nutrition. Univariate analyses showed significant differences. Multivariate analyses were performed on the three items of preterm delivery, defect size (over 50% to nearly entire defect), and ventilation for ≥ 9 days. We identified the latter two items as independent risk factors. The adjusted odds ratios were 4.65 (95% confidence interval, 1.27-7.03) and 6.02 (1.65-21.90), respectively. Delayed oral nutrition was related to a significantly higher probability of developmental delay at 18 months (crude odds ratio 4.16, 1.19-14.5). CONCLUSION: In patients with CDH, a large defect and ventilatory management over 9 days are independent risk factors for delayed oral nutrition, which is a potent predictor of developmental delay that requires active developmental care.

RESUMO

To clarify the feeling of knowing a name but not being able to recall it, known as having a "tip-of-the-tongue" (TOT) experience, we proposed a TOT model consisting of three stages combining a face recognition model and autonomic sympathetic nerve activity. Since TOT increases with age, we compared two age groups: young (N = 27, M = 20.4 ± 1.5 years) and middle-aged (N = 29, M = 58.5 ± 8.0 years). Experiment 1 showed that successfully naming low-frequency common names increased the skin conductance response (SCR) value, and the time to reach the maximum SCR value was longer. Experiment 2 was a naming task for face photographs. The younger group showed higher SCR values during successfully naming, while the middle-aged group showed similar SCR values for successfully naming and experiencing TOT. Both groups had the longest time to reach maximum SCR in TOT. In this study, physiological arousal of TOT was not affected by aging.

RESUMO

BACKGROUND: Recent studies have reported the high incidence of undescended testis (UDT) in patients with gastroschisis. Although various mechanical, hormonal, and genetic theories have been postulated to describe testicular descent, the mechanism contributing to this condition remains controversial. We aimed to investigate the incidence and risk factors of UDT in infants with gastroschisis. METHODS: Male neonates who underwent surgery for gastroschisis between January 1982 and December 2019 were enrolled. Data were analyzed regarding the prevalence of UDT, including spontaneous testicular descent and the necessity of orchidopexy. Patients were grouped into those with or without UDT to identify the risk factors for UDT. RESULTS: Among 38 patients with gastroschisis, six (15.8%) developed UDT. There were no significant differences in gestational age or birthweight between patients with and without UDT. The patients with UDT had a significantly larger defect size than those without UDT (P = 0.037). In addition, the timing of abdominal closure was significantly later in patients with UDT than in those without UDT (P = 0.004). None of the patients with UDT exhibited spontaneous testicular descent requiring subsequent orchidopexy. CONCLUSIONS: Patients with gastroschisis had a high prevalence of UDT. In gastroschisis, the incidence of UDT was related to the defect size and the timing of abdominal wall closure, indicating that an insufficient increase in intra-abdominal pressure during the fetal period may affect the development of UDT.

RESUMO

PURPOSES: Congenital biliary dilatation (CBD), defined as pancreaticobiliary maljunction (PBM) with biliary dilatation, is a high risk factor for biliary tract cancer (BTC). KRAS and p53 mutations reportedly affect this process, but the mechanisms are unclear, as is the likelihood of BTC later in life in children with CBD. We investigated potential carcinogenetic pathways in children with CBD compared with adults. METHODS: The subjects of this study were nine children with CBD and 13 adults with PBM (10 dilated, 3 non-dilated) without BTC who underwent extrahepatic bile duct resections, as well as four control patients who underwent pancreaticoduodenectomy for non-biliary cancer. We evaluated expressions of Ki-67, KRAS, p53, histone deacetylase (HDAC) and activation-induced cytidine deaminase (AID) in the biliary tract epithelium immunohistochemically. RESULTS: The Ki-67 labeling index (LI) and expressions of KRAS, p53, HDAC, and AID in the gallbladder epithelium were significantly higher or tended to be higher in both the children with CBD and the adults with PBM than in the controls. CONCLUSIONS: BTC may develop later in children with CBD and in adults with PBM, via HDAC and AID expression and through epigenetic and genetic regulation.

RESUMO

PURPOSE: To assess the risk factors for surgical site infections (SSIs) post-abdominal surgery in neonates. METHODS: A retrospective, single-center cohort study was conducted using patient data from 2009 to 2018. Patient characteristics and several variables were analyzed to identify independent risk factors for SSI. RESULTS: SSI occurred in 39/406 procedures (9.6%). Univariate analysis showed that the incidence of SSI was significantly higher in patients who had undergone multiple surgical procedures (P = 0.032), prolonged operations (P = 0.016), long-term hospitalization (P < 0.001), long-term antibiotic administration (P < 0.001), with methicillin-resistant Staphylococcus aureus (MRSA) colonization (P = 0.044), contaminated/dirty wounds (P < 0.001), and American Society of Anesthesiologists physical status of 3 or 4 (P = 0.021). Multivariate analysis identified prolonged operations [odds ratio (OR): 2.91 (1.21-8.01)] and contaminated/dirty wounds [OR: 5.42 (2.41-12.1)] as independent risk factors. Patients with SSI had a higher incidence of MRSA colonization (27.8% vs. 14.8%, P = 0.044), longer antibiotic administration (24 days vs. 8 days, P = 0.049), and longer hospitalization times (98 days vs. 43 days, P = 0.007) than those without SSIs. CONCLUSIONS: Long operations exceeding 100 min and surgical procedures with contaminated/dirty wounds are independent risk factors for neonatal SSIs after abdominal surgery. SSIs were related to MRSA colonization during hospitalization, long-term antibiotic administration, and long-term hospitalization.

RESUMO

PURPOSE: Fetuses with persistent cloaca are known to develop urine or meconium backflow into the abdominal cavity caused by obstruction of the common channel, thus leading to fetal peritonitis with fetal ascites. We analyzed the impact of prenatal fetal ascites on postnatal clinical features and management. METHODS: This retrospective single-center cohort study was conducted to compare the perinatal parameters of patients with isolated persistent cloaca who were born and treated at our hospital between 1991 and 2021. The clinical features and management of those with and without fetal ascites were compared. RESULTS: Among the 17 eligible patients, fetal ascites were recognized in seven. The occurrence of fetal ascites was significantly related to preterm birth, higher birth weight z-score, birth via emergency cesarean delivery, low Apgar scores at 1 min and 5 min, higher C-reactive protein levels at birth, longer duration of oxygen administration, the need for a urinary drainage catheter at initial discharge, and shorter neonatal hospital stays. CONCLUSIONS: The postnatal management of patients with persistent cloaca with fetal ascites differed significantly from that of patients without fetal ascites. For patients with unexplained fetal ascites, magnetic resonance imaging may be helpful for determining the definite diagnosis of persistent cloaca.

RESUMO

PURPOSE: This study aimed to evaluate prenatal predictors of mortality in fetuses with congenital diaphragmatic hernia (CDH). METHODS: A systematic literature search was performed to identify relevant observational studies that evaluated the ability of lung-to-head ratio (LHR), observed-to-expected LHR (o/e-LHR), observed-to-expected total fetal lung volume (o/e-TFLV), lung-to-thorax transverse area ratio (L/T ratio), intrathoracic herniation of the liver and the stomach, and side of diaphragmatic hernia, using a threshold for the prediction of mortality in fetuses with CDH. Study quality was assessed using the QUADAS-2 tool. Hierarchical summary receiver operating characteristic curves were constructed. RESULTS: A total of 50 articles were included in this meta-analysis. The QUADAS-2 tool identified a high risk of bias in more than one domain scored in all parameters. Among those parameters, the diagnostic odds ratio of mortality with o/e-LHR < 25%, o/e-TFLV < 25%, and L/T ratio < 0.08 were 11.98 [95% confidence interval (CI) 4.65-30.89], 11.14 (95% CI 5.19-23.89), and 10.28 (95% CI 3.38-31.31), respectively. The predictive values for mortality were similar between the presence of liver herniation and retrocardiac fetal stomach position. CONCLUSIONS: This systematic review suggests that o/e-LHR, o/e-TFLV, and L/T ratio are equally good predictors of neonatal mortality in fetuses with isolated CDH.

RESUMO

PURPOSE: It is important to confirm the existence of pulmonary metastases in pediatric patients with malignancies. Therefore, we aimed to investigate if computed tomography CT-guided marking is a feasible and safe method for the identification and resection of tiny pulmonary lesions in pediatric cancer patients. METHODS: We retrospectively reviewed the medical records of pediatric cancer patients who underwent CT-guided marking procedures in our institutions between Jan 2011 and Apr 2020. After 2015, these procedures were combined with an indocyanine green (ICG) navigation-guided surgery for hepatoblastoma cases. RESULTS: We targeted a total of 22 nodules in 12 patients. Of these, marking was successful in 18 (81.8%) nodules, 10 of which contained viable malignant cells. Complications caused by the marking procedures included mild pneumothorax and mild atelectasis in two patients, respectively. Of the eight resected nodules in patients with hepatoblastoma, four were ICG-positive and contained viable malignant cells. Two additional ICG-positive nodules, which were unidentified before surgery, were observed intraoperatively. CONCLUSION: CT-guided marking is a feasible and safe method that can be used to identify and resect tiny pulmonary lesions in pediatric cancer patients. An ICG navigation-guided surgery is useful when combined with CT-guided marking, particularly in hepatoblastoma cases.

RESUMO

Although the prognosis of brain abscesses has historically improved, the mortality rate still ranges from 5 to 32%, with ventricular perforation reaching 50% and 85-100% in fungal brain abscesses. The characteristic finding of ring-like enhancement by contrast-enhanced imaging is non-specific, and DWI, SWI and MR spectroscopy are very useful in differentiating brain abcesses from necrotizing brain tumors. Brain abscesses show apparent diffusion restriction on the DWI/apparent diffusion coefficient(ADC) map, whereas necrotizing brain tumors often show a weak diffusion restriction. The "dual rim sign" on SWI is also a highly specific finding of brain abscess.

RESUMO

Tau deposits is a core feature of neurodegenerative disorder following traumatic brain injury (TBI). Despite ample evidence from post-mortem studies demonstrating exposure to both mild-repetitive and severe TBIs are linked to tau depositions, associations of topology of tau lesions with late-onset psychiatric symptoms due to TBI have not been explored. To address this issue, we assessed tau deposits in long-term survivors of TBI by PET with 11C-PBB3, and evaluated those associations with late-life neuropsychiatric outcomes. PET data were acquired from 27 subjects in the chronic stage following mild-repetitive or severe TBI and 15 healthy control subjects. Among the TBI patients, 14 were diagnosed as having late-onset symptoms based on the criteria of traumatic encephalopathy syndrome. For quantification of tau burden in TBI brains, we calculated 11C-PBB3 binding capacity (cm3), which is a summed voxel value of binding potentials (BP*ND) multiplied by voxel volume. Main outcomes of the present study were differences in 11C-PBB3 binding capacity between groups, and the association of regional 11C-PBB3 binding capacity with neuropsychiatric symptoms. To confirm 11C-PBB3 binding to tau deposits in TBI brains, we conducted in vitro PBB3 fluorescence and phospho-tau antibody immunofluorescence labelling of brain sections of chronic traumatic encephalopathy obtained from the Brain Bank. Our results showed that patients with TBI had higher 11C-PBB3 binding capacities in the neocortical grey and white matter segments than healthy control subjects. Furthermore, TBI patients with traumatic encephalopathy syndrome showed higher 11C-PBB3 binding capacity in the white matter segment than those without traumatic encephalopathy syndrome, and regional assessments revealed that subgroup difference was also significant in the frontal white matter. 11C-PBB3 binding capacity in the white matter segment correlated with the severity of psychosis. In vitro assays demonstrated PBB3-positive tau inclusions at the depth of neocortical sulci, confirming 11C-PBB3 binding to tau lesions. In conclusion, increased 11C-PBB3 binding capacity is associated with late-onset neuropsychiatric symptoms following TBI, and a close correlation was found between psychosis and 11C-PBB3 binding capacity in the white matter.

RESUMO

AIM: While emotional processing is implicated in various psychiatric illnesses, its differences among diagnoses are unclear. We compared associative learning of social values in patients with depression and schizophrenia by measuring skin conductance response to interpersonal stimuli. METHODS: We included 20 female outpatients each with depression and schizophrenia. They underwent Pavlovian conditioning experiments in response to a classical aversive sound, and an interpersonal stimulus that was designed to cause aversive social conditioning with actors' faces coupled with negative verbal messages. Multiple regression analysis was performed to examine the associations between the degree of conditioned response and the clinical characteristics of the participants. RESULTS: Conditioned responses during the acquisition phase in both conditions were higher in depression compared to schizophrenia. Patients with depression successfully showed fear conditioning in both conditions, and they exhibited slower extinction in the interpersonal condition. The conditioned response during the extinction phase showed a positive association with Emotion Regulation Questionnaire Expressive Suppression score, and a negative association with the Emotion Regulation Questionnaire Cognitive Reappraisal score and the use of antidepressants. Patients with schizophrenia did not become conditioned in either of the conditions. The Positive and Negative Syndrome Scale Negative Syndrome score was negatively associated with the degree of conditioned response during the acquisition phase in the interpersonal condition. CONCLUSION: Female patients with schizophrenia, especially those who prominently demonstrated negative symptoms, suggested their intrinsic impairments in the associative learning of social context. Antidepressants and adaptive emotional regulation strategy may enhance the extinction learning of aversive social conditioning in depression.

RESUMO

PURPOSE: A congenital extrahepatic portosystemic shunt (CEPS) associated with hyperammonemia requires occlusion of the shunt vessels. We evaluated the effectiveness and safety of laparoscopic ligation of a CEPS in children with hyperammonemia. METHODS: The subjects of this retrospective study were seven children with hyperammonemia who underwent laparoscopic ligation of a CEPS. Their median age was 5.2 years (range 1-16 years). Before the laparoscopic procedure, a catheter was inserted through the femoral vein and placed in the portal vein via the shunt vessel. The shunt vessel was dissected and taped laparoscopically. After measuring the portal vein pressure under temporal occlusion, the shunt vessels were ligated. RESULTS: The types of shunts according to location were patent ductus venosus (n = 2), splenorenal shunt (n = 2), gastrorenal shunt (n = 2), and superior mesenteric vein-inferior vena cava shunt (n = 1). Laparoscopic ligation of the shunt vessel was completed uneventfully in all patients. The median portal vein pressure was 19 mmHg after ligation. The median preoperative blood ammonia level was 94 µg/dL (range 71-259 µg/dL), which decreased after ligation in all patients. There was no incidence of postoperative liver failure. CONCLUSION: Laparoscopic ligation of a CEPS is safe and effective for children with hyperammonemia.

RESUMO

PURPOSE: Although various artificial tracheas have been developed, none have proven satisfactory for clinical use. In-body tissue architecture (IBTA) has enabled us to produce collagenous tissues with a wide range of shapes and sizes to meet the needs of individual recipients. In the present study, we investigated the long-term outcomes of patch tracheoplasty using an IBTA-induced collagenous tissue membrane ("biosheet") in a beagle model. METHODS: Nine adult female beagles were used. Biosheets were prepared by embedding cylindrical molds assembled with a silicone rod and a slitting pipe into dorsal subcutaneous pouches for 2 months. The sheets were then implanted by patch tracheoplasty. An endoscopic evaluation was performed after 1, 3, or 12 months. The implanted biosheets were harvested for a histological evaluation at the same time points. RESULTS: All animals survived the study. At 1 month after tracheoplasty, the anastomotic parts and internal surface of the biosheets were smooth with ciliated columnar epithelium, which regenerated into the internal surface of the biosheet. The chronological spread of chondrocytes into the biosheet was observed at 3 and 12 months. CONCLUSIONS: Biosheets showed excellent performance as a scaffold for trachea regeneration with complete luminal epithelium and partial chondrocytes in a 1-year beagle implantation model of patch tracheoplasty.

RESUMO

BACKGROUND: The aim of this study was to investigate factors associated with the development of parenteral nutrition-associated liver disease (PNALD) and to examine the clinicopathological relationship of PNALD in extremely low-birthweight infants (ELBWI). METHODS: The subjects were 13 ELBWI who had received PN because of intestinal perforation or functional ileus between 2000 and 2013. We measured the serum levels of biochemical parameters, including aspartate aminotransferase, alanine aminotransferase, and direct bilirubin. Liver histopathology was examined in relation to outcome. The subjects were categorized into two groups on liver histopathology: F(+), development of hepatic fibrosis and necrosis with/without cholestasis; and F(-), no hepatic fibrosis. RESULTS: Of 13 ELBWI, five died of hepatic failure, five died of sepsis, and the other three were alive at the time of the study. Of the five infants who died of hepatic failure, two developed fulminant hepatitis without cholestasis, and the other three developed chronic cholestasis and finally hepatic failure. Postmortem histopathology in F(+) indicated not only massive hepatic necrosis, but also massive hepatic fibrosis. These histopathological findings explained the clinical presentation of portal hypertension. There were significant differences in the fasting period after intestinal disease onset between the two groups. CONCLUSION: The prolonged fasting with PN is responsible for severe hepatocellular necrosis with fibrosis and consequent lethal portal hypertension.

RESUMO

PURPOSE: Our previous experimental study of perforated peritonitis in rats proved that peritoneal lavage with strong acid electrolyzed water (SAEW) has no adverse effects, reduces the bacteria count in the ascitic fluid more effectively than saline, and increases the survival rate significantly. Thus, we conducted a randomized controlled study, applying SAEW in the treatment of perforated appendicitis in children. METHODS: Forty-four patients, aged 3-14 years, were randomly divided into two groups: Group S (n = 20), in which the peritoneal cavity was lavaged with 100 ml/kg saline and the wound was washed out with 200 ml saline; and Group E (n = 24), in which the peritoneal cavity was lavaged with 100 ml/kg SAEW and the wound was washed out with 200 ml SAEW. RESULTS: No adverse effect of SAEW was observed in Group E. There was no difference in the bacterial evanescence ratio of ascitic fluid after lavage between Groups S and E (11.1 and 15.8%, respectively). A residual abscess developed in one patient from each group (5.0 and 4.2%, respectively). The incidence of surgical site infection (SSI) was significantly lower in Group E than in Group S (0 and 20%, respectively; P < 0.05). There was no difference in the duration of pyrexia, positive C-reactive protein, leukocytosis, or hospital stay between the groups. CONCLUSION: Peritoneal lavage and wound washing with SAEW have no adverse effects and are effective for preventing SSI.

RESUMO

Some theories of emotion emphasise a close relationship between interoception and subjective experiences of emotion. In this study, we used facial expressions to examine whether interoceptive sensibility modulated emotional experience in a social context. Interoceptive sensibility was measured using the heartbeat detection task. To estimate individual emotional sensitivity, we made morphed photos that ranged between a neutral and an emotional facial expression (i.e., anger, sadness, disgust and happy). Recognition rates of particular emotions from these photos were calculated and considered as emotional sensitivity thresholds. Our results indicate that participants with accurate interoceptive awareness are sensitive to the emotions of others, especially for expressions of sadness and happy. We also found that false responses to sad faces were closely related with an individual's degree of social anxiety. These results suggest that interoceptive awareness modulates the intensity of the subjective experience of emotion and affects individual traits related to emotion processing.

RESUMO

Recent studies in cognitive neuroscience have suggested that the integration of information about the internal bodily state and the external environment is crucial for the experience of emotion. Extensive overlap between the neural mechanisms underlying the subjective emotion and those involved in interoception (perception of that which is arising from inside the body) has been identified. However, the mechanisms of interaction between the neural substrates of interoception and emotional experience remain unclear. We examined the common and distinct features of the neural activity underlying evaluation of emotional and bodily state using functional magnetic resonance imaging (fMRI). The right anterior insular cortex and ventromedial prefrontal cortex (VMPFC) were identified as commonly activated areas. As both of these areas are considered critical for interoceptive awareness, these results suggest that attending to the bodily state underlies awareness of one's emotional state. Uniquely activated areas involved in the evaluation of emotional state included the temporal pole, posterior and anterior cingulate cortex, medial frontal gyrus, and inferior frontal gyrus. Also the precuneus was functionally associated with activity of the right anterior insular cortex and VMPFC when evaluating emotional state. Our findings indicate that activation in these areas and the precuneus are functionally associated for accessing interoceptive information and underpinning subjective experience of the emotional state. Thus, awareness of one's own emotional state appears to involve the integration of interoceptive information with an interpretation of the current situation.
