Abstract
BACKGROUND On February 6, 2023, a series of mega-earthquakes (MEs) struck the southern parts of Turkey and northern Syria. In the first 16 days after the Turkey MEs (TMEs), the Tokushukai Medical Assistant Team (TMAT) backed by its infrastructure visited Turkey to support a local hospital. With the goal of helping local communities and working with local supporters and authorities, Turkey is on a mission to positively impact people's lives. METHODS Data collected covered the TMAT support period in February 2023. All patients admitted to a hospital were registered through the Minimum Data Set (MDS) of the Emergency Medical Team (EMT) Coordination Cell (EMTCC). RESULTS A total of 561 patients were hospitalized during the 16-day mission. A review of the MDS data showed a de-crease in the number of inpatients. The number of diseases directly related to the disaster was confirmed to be due to a gradual decrease in TME aftershock. However, the number of patients with nondisaster-related disease remained stable. CONCLUSION The experience of EMT in the initial relief of MEs that struck Turkey and Syria on February 6, 2023 showed that a mobile type 1 EMT in the early stage while rebuilding the infrastructure is essential. From the analysis of patient profiles, it is clear that knowledge and experience of skin diseases is needed in the first minutes of MEs. In addi-tion, it has become clear that to ensure the quality of MDS for further analysis and to improve the efficiency and effec-tiveness of EMS, it is essential to have recorders in the EMS. These MDS recorders, called descriptors, must be isolated from the treating medical staff to eliminate subjectivity and ensure data accuracy.

Intussusception as a Presentation of Anisakis Infestation in the Global Era of Raw Fish Consumption: A Case Report and Literature Review. Cureus 2024; 16:e55232. [PMID: 38558575 PMCID: PMC10981383 DOI: 10.7759/cureus.55232] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 02/29/2024] [Indexed: 04/04/2024] Open
Abstract
Anisakiosis, also known as Anisakis larvae infestation, is an increasing parasitic infestation due to the worldwide spread of raw fish and shellfish consumption habits. We present a rare presentation of intestinal intussusception as a preoperative diagnosis and noticed it postoperatively due to Anisakis larvae. A 43-year-old man presented to the emergency department with abdominal pain around the umbilicus and vomiting for several hours. On physical examination at presentation, he had tenderness in the lower abdomen. His radiological studies showed a right-sided pseudo-kidney sign and ileo-colonic intussusception on ultrasound echography. His computed tomography images added findings of submucosal edema and wall thickening in the terminal ileum, swollen regional lymph nodes, and ascites. An urgent laparotomy was performed for ileo-colonic intussusception of an unknown cause. During the laparotomy, the ileocecal intussusception was manually reduced after dissecting the adhesion due to the previous appendectomy, and a partial ileotomy was undertaken using the Endo-GIA automatic anastomosis device. At the resected ileal wall surface, the presence of Anisakis larvae was noticed, and anisakidosis was diagnosed. The dietary history taken post-operatively revealed that he had eaten salmon, bonito, and squid sashimi four days prior to his emergency department visit. His postoperative course was uneventful, and he was discharged from the hospital on the fifth day postoperatively. Anisakiosis must be in the differential diagnosis of intussusception, and eating history seems like a cue to diagnose, and it might be meaningful to clinicians.

Abstract
Background Tokunoshima is a remote island in the Amami Islands, 470 km southwest of the Kagoshima mainland. It has a population of 23,000 and consists of three towns: Tokunoshima, Isen, and Amagi. Three medical institutions on the island are responsible for blood transfusion medicine, but there is no blood stockpiling station on the island, and blood is stockpiled in each of the hospitals. Although Tokunoshima Tokushukai Hospital is responsible for 70% of transfusion medicine on Tokunoshima, it is difficult to maintain a sufficient amount of blood in stock considering disposal. Aim To determine whether changing the distribution of blood types in a hospital's stockpile would reduce the transfusion disposal rate. Methods This was a retrospective survey. By changing the in-house stock of blood products for transfusions delivered to our hospital over 10 years from January 2013 to December 2017 (preintervention) and from January 2018 to December 2022 (postintervention), we compared the cost-saving effects of these two intervention strategies on disposal rates and blood inventories, as well as the survival rates of case profiles requiring transfusion interventions in hospital-donated transfusion and ABO-incompatible transfusion between two periods. The hospital's stock of RBC had changes that storage of type (A, B, O, AB) RBC from (4, 4, 4, 2) units in the pre-interventon to (2, 2, 6, 0) units in the postintervention. Results The annual blood product waste rate decreased from 23.4% in the preintervention period to 17.9% in the post-intervention period. Conclusion By changing the blood products stockpiled for transfusion medicine in Tokunoshima, the transfusion disposal rate can be reduced.

A useful modality of CT angiography image to identify medical emergency in isolated celiac artery dissection type I: A case report with longest follow-up and literature review. Radiol Case Rep 2023; 18:4294-4298. [PMID: 37771382 PMCID: PMC10522870 DOI: 10.1016/j.radcr.2023.09.004] [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: 08/17/2023] [Revised: 08/28/2023] [Accepted: 09/01/2023] [Indexed: 09/30/2023] Open
Abstract
Symptomatic isolated celiac artery (CA) dissection (SICAD) is an extremely rare form of visceral artery dissection. It is diagnosed by a contrast abdominal computed tomography (CT) scan showing a CA dissection (CAD). There are 4 types of CAD: Type I-IV. Type I has entry and re-entry and no true luminal narrowing. All types other than type I have entry and re-entry. They have true lumen compression and true lumen constriction due to false lumen. We report a case with the longest follow-up, 120 months after symptom onset, without evidence of CAD exacerbation. A 56-year-old man presented with a sudden onset of abdominal and back pain. He had a past medical history of left pneumothorax, pulmonary tuberculosis at the age of 23, and hypertension on medication since the age of 46. On physical examination, he had mild muscle rebound tenderness in the epigastric region. The curved multiplanar reconstruction (MPR) of the urgent 3-dimensional contrast-enhanced abdominal computed tomography angiography (CTA) showed an isolated celiac artery dissection type I. Given the risk of emergency surgery for total occlusion of the CA, conservative management with analgesics during hospitalization resolved the abdominal pain, and the patient was discharged 3 days later. Subsequently, a total of 5 CTAs were performed over 120 months, but no worsening of CA arterial dissection and CA occlusion findings were observed. In type I SICAD cases, arterial dissection, and CA occlusion may progress, in which case emergency stenting or endovascular treatment may be indicated, and close follow-up such as CTA is required.

Abstract
The prevalence of hepatic cyst (HC) ranges from 2.5 to 4.7%. Among them, HCs with with symptoms occur in 15%. Extrahepatic rupture of HCs with hemorrhagic shock and death may occur. Early detection of intracystic hemorrhage is necessary to prevent lifethreatening complications. In this case, a 77-year-old woman underwent regular checkups. Her ultrasound (US) showed multiple hepatic cysts (HCs). The largest HC was 80 mm in diameter and located in segment 8 of the right lobe. Her prognostic nutritional index (PNI) was 41.7, indicating high surgical morbidity and mortality after surgery. Multidetector computed tomography (MDCT) and magnetic resonance imaging (MRI) were added to identify intra- and extra-cystic anatomy. Compared to MDCT, MRI was able to identify intra-cystic heterogeneous low and high intensity. These findings were interpreted to indicate acute to chronic intra-cystic hemorrhage. As a complication of the rupture and death, an anterior segmentectomy with segmentectomy with cholecystectomy was planned and performed. Her postoperative course was uneventful and she was discharged on day 16. The life-threatening complex HCs include intra-cystic hemorrhage, rupture, hemorrhagic shock and death. To prevent these, we would like to emphasize that MRI appears to be superior to US or CT in providing accurate information on the time course of intra-cystic hemorrhage from hemoglobin to hemosiderin changes to guide urgent surgical intervention of hepatectomy to prevent HC rupture and prevent HC rupture and death.

Abstract
A 31-year-pld female patient, presented to the emergency room with vaginal bleedingand a three day history of left sided lower abdominal pain. he showed shock status and an'' as ``She came in with a hypovuoluminc shock and an enhanced 3-dimensional multidetector-computed tomography (3D-MDCT) images showed a specific teardropping owl's eye appearance consistent with an active bleeding around fetal sac and from ruptured tubal ectopic pregnancy (EP) spreading into peritoneum at the 9th gestational week. According to accurate radiological diagnosis, she has been able to receive a successful urgent transportation via helicopter to the consultee obstetricians and received an urgent salpingectomy with the diagnosis of tubal rupture in EP. Her post-surgical course was uneventful and discharged hospital on 8th day. From this case experience, an urgent diagnosis of a ruptured tubal EP in shocked female using not US but MDCT is accurately diagnosed because MDCT has radiological advantage to visualize active hemorrhage using contrast-medium.

Abstract
In rural areas, the medical resources are extremely limited not only pandemic but non-pandemic period. Tele-healthcare system using digital technology-based telemedicine is widely used across various medical specialties. To solve limitation of medical resources in hospital located in remote isolated areas, telehealthcare system using smart application has been applied to access expert opinions in pre-coronavirus disease (COVID-19) era since 2017. The COVID-19 has spread also in this island during COVID-19 period. We have experienced three consecutive neuroemergency patients. Their ages and final diagnoses were: 98 years with subdural hematoma (case 1), 76 years with post-traumatic subarachnoid hemorrhage (case 2), and 65 years with cerebral infarction (case 3), respectively. The tele-counseling could save two of three transportations to tertiary hospital and also save 6,000 US dollars per case for transportation by helicopter. From these three cases counseled through smart app which has been started to use 2 years before COVID-19 emerged in 2020, what this case series would report are the following two viewpoints: (1) medicoeconomic benefits exist in tele-healthcare system in COVID-19 era and (2) developing telehealthcare systems must be prepared that is available even when the electricity system has been shut down, for instance solar system that could. This system must be developed when non-disaster period for disaster days of natural disasters and human-related disasters including wars and terrorisms.

Abstract
Cases with iliopsoas abscess (IPA) in a single hospital-based cases were reviewed and compared with clinical profiles of published hospital-based IPA series. To verify usefulness of prognostic nutritional index (PNI) used to predict outcome and severity of IPA, this study was performed. This study consists of 2 parts: Study 1 - Case review of IPA series in a single hospital: 7 cases with IPA treated in a single hospital in sequential 5 years were collected (series 1) and their clinical profiles compared. Study 2 - Review of hospital-based literature: A search of the PubMed database from 1990 to the present was performed, using the Boolean expression ([Psoas OR iliopsoas] AND [abscess] AND [hospital-based]). Two hospital-based case series were collected. The clinical profiles of 2 series were compared with series 1 to draw predictive factors of outcome and deciding treatment modality, medical or surgical. Study 1 - Analyzing 7 IPA cases, average age was 76.7 years old (varying from 64 to 91) and the lifesaving rate was 86%. PNI < 45, calculated with serum albumin (Alb) and total lymphocyte count, and larger cumulative abscess volume (CAV) measured by computed tomography seem outcome predictors. Study 2 - Analyzing 2 hospital-based IPA series (series 2 and 3), series 2 reviewed isolated IPA cases without any comorbidities and series 3 reviewed IPA cases with cardiovascular disorders. Among 3 series including ours, series 1 showed oldest case and longer length of hospitalization. Series 3 showed the highest mortality among 3 because it collected IPA with cardiovascular comorbidities. PNI seems predictors of outcome and disease activity in patients with IPA and might indicate treated with surgical intervention.

Abstract
A 72-year-old female diagnosed with rectal cancer treated with a surgical procedure was reported. As 3 liver metastases (LMs) appeared in multidetector CT, adjuvant chemotherapy using Bevacizumab combined with modified FOLFOX-6 was completed. LMs were changed to cystic lesions during the follow-up period, consistent with liquefactive necrosis. These cystic lesions that appeared in the course of disappearing LMs (DLMs) were identified by CT as homogeneous low signal intensity in hepatocyte specific Gd-enhanced MRI. This might be pathognomonic radiological footprint equivalent to liquefactive necrosis observed in the process of DLM and must be carefully followed in the course of radiological complete response. The radiological changing findings of LMs to cystic changes, high sensitivity of detecting DLM, and limitations of Gd-MRI might be meaningful to clinicians.

Abstract
The hepatocellular carcinoma (HCC) with intrahepatic and bone metastasis shows poor survival of averagely 3 months. The bone metastasis and HCC itself might cause cancer-associated pain. An intrathecal (IT) analgesia might contribute to improve QOL and prolong surviving time (ST). A 71-year-old male presented with temperature and appetite loss continuing for 2 months. He looked pale and malaise. Computed tomography and tumor markers elevation confirmed diagnosis of HCC stage IV. To treat him, molecularly targeted therapy was started but abandoned because of side effects of life-threatening convulsions and loss of consciousness. Since this time, pain control strategy was planned as advance care plan. After dermal and oral opioids were administered, IT analgesia was introduced to conquer uncontrollable pelvic pain due to metastatic osteolytic lesions. Owing to IT analgesia against severe cancer-related pain, he had lived for 46 months. Comparing with reviews in which average ST is 3 months, this is the case with the longer ST in bone-metastatic HCC. From our experience, it must be emphasized that relieving cancer-related pain strategy for patients with progressive bone-metastatic HCC might contribute to prolong ST longer when adjuvant therapy has been failed.

Abstract
A 79 years male with fishbone-induced acute appendicitis was treated surgically with laparoscopic procedure. In preoperative diagnostic study, 3-dimensional multidetector-computed tomography (3D-MDCT) demonstrated the foreign body in the appendix and 3D-reconstructed images seemed fishbone with sharp-pointed dorsal fin directing to the tip of the appendix. With these findings, surgical indication of appendectomy was confirmed and laparoscopic appendectomy was performed. He made a full recovery and was discharged in a satisfactory condition following 7 days of post-operative treatment. From this case experience, 3D-MDCT seems helpful to visualize details of foreign bodies in the appendix, and valuable to confirm surgical indication of complicated acute appendicitis.

Abstract
An invasive aspergillosis (IA) primarily occurs among immunocompromised patients. Recently with an influenzae infection prevalently spreading, influenzae-associated invasive aspergillosis (IAIA) has been reported occasionally. By contrast, neuroleptic malignant syndrome (NMS) occurs rarely in psychiatric patients who are treated with Olanzapine. We report a 43 years old male with psychiatric disorder who had developed IAIA followed by NMS and cerebral hemorrhage as the result of aspergillus invasion to cerebral vessels. He had also super-infection of COVID-19, 13 months later to be saved completely after invasive mechanical respiratory supports. From clinical aspects, we would emphasize that it is of importance to find earlier co-occurrence of IAIA patients with cerebral hemorrhage due to secondary infectious vasculopathy of IA.

Abstract
An isolated superior mesenteric artery (SMA) dissection (ISMAD) is extremely rare among visceral artery dissections. Its diagnosis is made by abdominal contrast CT scan which shows SMA occlusion partially or completely. The ISMAD is classified into 6 types: type I–V has partial occlusion and treated medically using antiplatelets or anticoagulants. On the other hand, type VI has complete occlusion and must be treated by urgent surgical operation. We present a 67-year-old female who presented with sudden onset abdominal pain and melena. An urgent contrast CT revealed type VI ISMAD. She underwent 3 staged operations as follows: (1) first, as laparotomy showed pale color in almost the extensive length of the small intestine, arterial bypassing of SMA was undertaken using SMA to the right common iliac artery bypass; (2) as the second-look operation on the next day, the terminal ileum was resected, and the remaining small intestine was able to be preserved. However, when the abdomen was tried to be closed, systemic blood pressure decreased to pre-shock condition, so the abdominal wall was closed at skin level with silastic sheet. (3) As the third-look operation on the 7th day, ileostomy was created, and the abdominal wall was safely closed. The postoperative course was uneventful. This case study shows that SMA grafting and staged operations might be an option to preserve the length of the small intestine when ISMAD is diagnosed as type VI.

Abstract
BACKGROUND AND OBJECTIVES The American Society for Parenteral and Enteral Nutrition recommends hypocaloric feeding for critically ill patients with a BMI of >=30.0 kg/m2. However, the cut-off value of obesity in Japan is BMI >25.0 kg/m2, due to the higher prevalence of type 2 diabetes mellitus, and cardiovascular risk factors, even at a lower BMI than in Western populations. Thus, the optimal energy intake for critically ill, overweight Asian patients is unknown. METHODS AND STUDY DESIGN A retrospective chart review was conducted in patients with BMI of >=25.0 kg/m2 in an emergency intensive care unit (EICU). Patients were categorized into two groups by average daily energy intake during the first week in the EICU, with Group A at <50% of requirement and Group B at >=50%. RESULTS A total of 72 patients with a median BMI of 27.5 kg/m2 were included in the study. No significant differences between the groups were observed for all-cause mortality, ICU-free days, or length of hospital stay. The number of ventilator-free days (VFDs) was significantly higher in Group A than Group B (20.0 [15.5-24.5] vs 17.0 [2.0-21.0] days; p=0.042). On multiple adjusted analysis, however, we found that %energy intake/requirement was not independently associated with VFDs (regression coefficient=0.019; 95% confidence interval, -0.115-0.076). CONCLUSIONS Energy intake in the first week in the EICU did not influence clinical outcomes in critically ill, overweight Japanese patients. Confirmation of these results in larger, randomized trials is required.

Abstract
Objective This study was performed to determine the cut-off point of the Functional
Independence Measure (FIM) to discriminate patients with acute stroke who
develop adverse events during their stay in a stroke care unit (SCU). Methods All consecutive patients with stroke admitted to a single institute from
January to March 2015 were enrolled. They were divided into two groups
according to their average daily energy intake in the SCU: ≥66% or <66%
of the target (high- and low-energy group, respectively). A receiver
operating characteristic curve was used to determine the cut-off point of
the FIM to predict adverse events in patients with acute stroke. Results The length of stay in the SCU was significantly longer and the serum
C-reactive protein level (CRP) was significantly higher in the low- than
high-energy group (7 vs. 4 days and 2.15 vs. 0.20 mg/dL, respectively). The
total FIM score cut-off value was 63 points. Conclusions An energy intake of <66% of the target was associated with a significantly
longer stay in the SCU and a higher CRP level. A total FIM score cut-off
value of 63 points is useful to discriminate patients with adverse events
among those with acute stroke.

Elevated Serum AA/EPA Ratio as a Predictor of Skeletal Muscle Depletion in Cachexic Patients with Advanced Gastro-intestinal Cancers. ACTA ACUST UNITED AC 2018; 31:1003-1009. [PMID: 28882973 DOI: 10.21873/invivo.11161] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2017] [Revised: 06/10/2017] [Accepted: 06/12/2017] [Indexed: 12/16/2022]
Abstract
BACKGROUND In recent years, the number of cancer patients has increased. Cancer patients are prone to sarcopenia as a result of the decrease in muscle mass and muscle weakness which occurs in cancer cachexia. Attention has been given on the effects of fatty acid administration on cancer patients. MATERIALS AND METHODS We conducted a retrospective chart-review study of consecutive patients with unresectable advanced GI cancer (stage IV) (n=46) receiving chemotherapy treatment in an outpatient or in-hospital setting between December 2012 and September 2015 at our Institution. The collected data were characteristics, psoas muscle area as measured by computed tomography (CT), and biochemical blood test and serum fatty acid profiles. Three methods of analysis were evaluated: (i) Comparison of biomarkers between two groups: psoas muscle index change rate (ΔPMI) decrease group vs. ΔPMI increase group. (ii) Correlation between ΔPMI and biomarkers. (iii) Multiple regression of ΔPMI and biomarkers Results: In the ΔPMI decrease group, n-6/n-3 ratio and AA/EPA ratio in the decrease group were significantly higher than those in the increase group. Among all parameters, serum EPA was positively and significantly related to ΔPMI (CC=0.443, p=0.039). In contrast, serum CRP, AA/EPA ratio and n-6/n-3 ratio were negatively related to ΔPMI (CC=-0.566, CC=-0.501, CC=-0.476, p=0.006, p=0.018, p=0.025, respectively). On multiple regression analysis, serum CRP value was strongly related to ΔPMI (r2=0.421, β=-0.670, p=0.001). CONCLUSION Higher n-6/n-3 and AA/EPA ratios were associated with a decrease in psoas muscle area, that lead to diagnosis of sarcopenia. Higher CRP was also associated with a decrease in psoas muscle area, suggesting that this might be an indicator of cachexic skeletal muscle depletion in cachexic patients with advanced gastro-intestinal cancers.

Abstract
BACKGROUND Although nutrition support is essential in intensive care units, optimal energy intake remains unclear. Here, we assessed the influence of energy intake on outcomes of critically ill, underweight patients. METHODS A retrospective chart review was conducted in patients with body mass index (BMI) of <20.0 kg/m(2) in an emergency intensive care unit (EICU). Patients were categorized into 4 groups by initial Sequential Organ Failure Assessment score (I-SOFA) and average daily energy intake during the first week: group M-1, I-SOFA ≤8 and <16 kcal/kg/d; group M-2, I-SOFA ≤8 and ≥16 kcal/kg/d; group S-1, I-SOFA >8 and <16 kcal/kg/d; and group S-2, I-SOFA >8 and ≥16 kcal/kg/d. RESULTS The study included 51 patients with a median age of 69 years. No significant differences were noted in all-cause mortality and length of stay in the EICU and hospital between groups M-1 and M-2 or groups S-1 and S-2. The mechanical ventilation duration (MVD) was significantly shorter in group M-1 than M-2 (2.7 [1.0-5.7] vs 9.2 [4.2-17.4] days; P = .040) and in group S-1 than S-2 (3.1 [0.7-6.0] vs 8.8 [6.1-23.1] days; P = .006). The number of patients who underwent tracheostomy in hospital was significantly lower in group S-1 than in S-2 (20% vs 32%; P = .002). Multivariable analyses to adjust for confounders revealed that average energy intake during the first week in EICU was a significant factor independently associated with MVD but not with the requirement of tracheostomy. CONCLUSION Reduced energy intake during the first week in EICU was associated with a reduced MVD in clinically ill patients with BMI <20.0 kg/m(2).

Abstract
We investigated the effects of treatment with antibodies against tumor necrosis factor (TNF)-α on energy metabolism, nutritional status, serum cytokine levels in patients with Crohn’s disease (CD). Twelve patients were enrolled. Resting energy expenditure (REE) levels were measured by indirect calorimetry. Crohn’s disease activity index (CDAI) significantly decreased after treatment with anti-TNF-α therapy. Anti-TNF-α therapy did not affect REE, but respiratory quotient (RQ) significantly increased after treatment. Serum interleukin-6 levels were significantly decreased and RQ were significantly increased in high REE (≥25 kcal/kg/day) group as compared to low REE (<25 kcal/kg/day) group. In conclusion, high REE value on admission is a predictive factor for good response to treatment with anti-TNF-α antibodies in active CD patients.

Abstract
BACKGROUND While previous studies have reported that feeding protocols improved clinical outcomes in critical care settings, the evidence supporting the application of feeding protocols in older patients has not yet been assessed. Here, we evaluated the effects of a feeding protocol in older patients fed through percutaneous endoscopic gastrostomy (PEG) tubes. METHODS We conducted a retrospective chart review of 109 patients aged >=65 who underwent PEG placement between April 2010 and March 2012 at a single acute care hospital. The protocol group was administered enteral nutrition (EN) according to a feeding protocol, while the non-protocol group was administered EN at the attending physician's discretion. RESULTS Length of hospital stay (LOS) overall and after EN initiation were significantly shorter in the protocol group than in the non-protocol group. (LOS: p=0.001; LOS after EN initiation: p=0.026). During the second week after EN initiation, significantly fewer patients had percutaneous oxygen saturation (SpO2) <93% and required oxygen therapy in the protocol group (p=0.032 for both comparisons). Nutrition intakes via PEG in the protocol group were significantly greater from Days 6 to 13 for energy and from Days 6 to 11 for protein compared with the non-protocol group. CONCLUSION The application of a feeding protocol after PEG placement in older patients was associated with shorter LOS, more efficient EN delivery, and lower incidence of low SpO2 than non-protocol group. Larger prospective studies are required to determine whether a feeding protocol is useful in improving health outcomes in this population.

Abstract
INTRODUCTION Stroke accounts for approximately 10% of all deaths. We examined whether energy intake influences the survival rate of severely ill stroke patients. METHODS We analyzed 86 consecutive severely ill stroke patients. Patients' background was compared between survivors and non-survivors. Average energy intakes in seven different periods from day one to seven following neurosurgical care unit (NCU) admission were compared between two groups, to examine which period is proper to show an energy difference. Groups were stratified by average total energy intake (group E-I, -II, -III, and -IV; ≤.25, 8.25-16.5, 16.5-25, and >25kcal/kg/day, respectively), and cumulative survival rate for 90 days after NCU admission was analyzed. Hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated to examine the effect of confounder factors. RESULT Patients' background did not differ significantly between the two groups. Average daily energy intake for the first seven NCU days of non-survivors was significantly lower than that of survivors (p=0.034). The survival rate of group E-II was significantly higher than that of group E-I, which was set as a reference (p=0.030). The adjusted HR of E-II was also significantly lower than that of group E-I (HR=0.19, p=0.047), although E-III did not show significance (HR=0.52, p=0.279). CONCLUSION Energy intake assessment should be conducted for at least seven days following NCU admission. An average total energy intake ranging from 8.25 to 16.5 kcal/kg/day and enteral feeding increases survival rate in severely ill stroke patients.

Evaluation of chlorinated benz[a]anthracene on hepatic toxicity in rats and mutagenic activity in Salmonella typhimurium. ENVIRONMENTAL TOXICOLOGY 2013; 28:21-30.

Abstract
Chlorinated benz[a]anthracenes (Cl-BaA) are halogenated aromatic compounds (typified by dioxins) found in the environment at relatively high concentrations. Fischer 344 rats were intragastrically administered 0, 1, or 10 mg of Cl-BaA or its parent compound benz[a]anthracene (BaA) per kg of body weight for 14 consecutive days. Both chemicals at 10 mg/kg/day inhibited the gain in body weight, and consequent increase in relative liver weight. Hepatic gene expression of cytochrome P450 (CYP) 1A1, 1A2, and 1B1 was significantly stimulated by administration of BaA (10 mg/kg/day) compared with the control. After administration of Cl-BaA, only the CYP1A2 gene was significantly induced, even at the lower dosage; CYP1A1 and 1B1 mRNA levels remained unchanged in Cl-BaA-treated rats compared with controls. To elucidate the role of such Cl-BaA exposure and induced CYPs at toxicity onset, we investigated the mutagenicity of BaA and Cl-BaA using Salmonella typhimurium TA98 and TA100. BaA and Cl-BaA at 10 μg/plate produced positive results in both strains in the presence of rat S-9. Incubation of Cl-BaA with recombinant rat CYP1A2 produced a significantly higher number of revertant colonies in TA98 and TA100 than in controls, but no such change was observed for BaA. In conclusion, BaA changes its own physiological and toxicological actions by its chlorination; (1) daily exposure to Cl-BaA selectively induces hepatic CYP1A2 in rats and (2) Cl-BaA induces frameshift mutations in the presence of CYP1A2, although BaA does not exert mutagenicity. This indicates that CYP1A2 may metabolize Cl-BaA to active forms.

Abstract
Cloacal dysgenesis sequence (CDS) is a rare and lethal malformation. We report such a case of long-term survival, currently to 12 years of age. In the fetal period, she received a timely placement of vesico-amniotic shunt for a megabladder due to a severe urethral obstruction. Postnatally, cystostomy and colostomy were created because of no perineal opening of urethra, vagina, and anus. Anorectoplasty, construction of efferent conduit, and colostomy closure were performed at 4 years of age. Ileovaginoplasty and ileovesicostomy which was a Mitrofanoff-type of conduit, and labioplasty were performed at the age of 11 years. To the best of our knowledge, only five survivors with CDS over 1 year of age have been reported.

Abstract
BACKGROUND The aim of the present study was to determine whether nutrition assessment helps predict clinical outcomes (COs) in infants who have undergone cardiac surgery. METHODS Study subjects were infants, aged less than 18 months, who had undergone cardiac surgery between April 2007 and August 2008. The nutrition parameters assessed include Onodera's prognostic nutritional index (PNI), height for age, weight for height, and weight for age. COs included mortality rate during hospitalization, length of stay in intensive care unit (LOS-1), length of stay in the hospital after surgery (LOS-2), and duration of mechanical ventilation support. Method-1: the correlation between nutrition parameters and COs was examined by statistical analysis. Method-2: the cutoff point of nutrition parameters was determined using the minimum P value approach. RESULTS The following results were obtained: Results-1: PNI was the only nutrition parameter found to be correlated with LOS-1. Results-2: the cutoff point for PNI as a predictor of LOS-1 was 55. CONCLUSIONS It appeared that preoperative PNI was the most influential factor on LOS-1 for infants after they underwent cardiac surgery. The PNI cutoff point 55 in infants who underwent cardiac surgery seems to be the best predictor of CO.

Abstract
The purpose of this study was to evaluate the tensile bond strength (TBS) to peroxide-exposed dentin. Furthermore, the effect of ascorbic acid (AA) on the bond strength of peroxide-exposed dentin was investigated. Extracted bovine dentin was exposed to 10% carbamide peroxide, 30% hydrogen peroxide, or distilled water for 30 min, then treated with 10% AA (0, 30, 90, and 180 min), and conditioned with 10% citric acid/3% ferric chloride. The polymethyl-methacrylate (PMMA) rod was bonded to the treated bovine dentin with 4-META/MMA-TBB resin. A minidumbbell-shaped bonded specimen was prepared from these bonded assemblies and the TBS was tested. The fractured surfaces were also observed with a scanning electron microscope. Exposure to peroxide before bonding significantly reduced bond strength. The application of AA to the peroxide-exposed dentin increased bond strength. On the other hand, an adverse effect of AA was found in distilled water-affected dentin. Extended resin fibers were partially seen in the peroxide-exposed dentin. In conclusion, peroxide reduced the bond strength, and the stronger the oxidation, the weaker the obtained bond. Antioxidation with AA recovered the bond strength, and this effect increased the longer the AA was applied.

Abstract
PURPOSE Although intussusception has been reported as quite a rare cause of jejunoileal atresia (JIA), pediatric surgeons have noted the frequent presence of intussusception as well as volvulus at surgery. The aim of this study was to investigate the contribution of intrauterine intussusception and volvulus to the development of JIA. METHODS In 48 newborns (24 boys and 24 girls) treated for JIA at our hospital between 1978 and 2004, the operative and pathologic findings were reviewed. RESULTS Intussusception was responsible for gap and cord type atresia in 12 cases (25%). The cord showed an atrophic intestinal lumen in 2 cases. Volvulus was observed in 13 cases. Volvulus and intussusception were simultaneously noted in 1 case. This suggested that intussusception was the cause of the atresia, whereas volvulus was a secondary event. Neither intussusception nor volvulus was observed in high jejunal, apple peel, or multiple atresia. CONCLUSIONS Intrauterine volvulus and intussusception were commonly observed in single mid- and low JIA. Thus, intrauterine intussusception may be a common cause of gap and cord type JIA. Volvulus may not only cause JIA but also result from anatomic changes after the development of JIA in some cases.

Abstract
BACKGROUND/PURPOSE The mechanisms of intrauterine vascular disruptions that result in the development of jejunoileal atresia (JIA) are not fully understood. Monochorionic twinning with fetal death of a cotwin is known to be correlated with the development of JIA in the survivor through placental communication. The aim of this study was to evaluate whether other placental vascular compromises might contribute to the development of JIA. METHODS Forty-five newborns (23 boys and 22 girls) who were treated for JIA at Tsukuba University Hospital from 1978 to 2003 were reviewed. Placental findings were informative in 23 cases. RESULTS No or slight abnormality of the placenta was found in 19 cases. Significant placental abnormalities were found in 4 patients who also had a low birth weight. One patient with apple peel atresia (APA) had excessive torsion of the umbilical cord (UC), which was inserted at the margin of the placenta, and there was an adjacent area of infarction. One patent with multiple atresia (MA) was a surviving monochorionic twin with intrauterine fetal death of the other. Another case of MA showed marginal insertion of the UC. Severe placental abnormalities including wide infarction, cyst formation, and marginal insertion of the UC were found in 1 case of MA. These 3 cases of MA were complicated with other anomalies including brain anomaly. CONCLUSIONS Placental vascular compromises were involved infrequently in JIA but might possibly be responsible for the development of JIA as well as associated anomalies and a low birth weight as chronic insults since an early stage of gestation in some cases.

Abstract
1. The accuracy of measurements of flow rate and concentrations of O2 and CO2 in expiratory gas by indirect calorimetry (IC) using paediatric and adult circuits were assessed by mass spectrometry and a pneumotachogram, which have been proven as the most reliable instruments for these purposes. 2. In the paediatric circuit, all measurements were demonstrated to be reliable: error rates for flow rate, O2 concentration and CO2 concentration were +3.13, +2.66 and -6.63%, respectively. All were within the 10%, which is acceptable as a biological error. 3. However, in the adult circuit of IC, all measurements were reliable except for measurements of CO2 concentration: error rates for flow rate, O2 concentration and CO2 concentration were +2.82, +1.64 and +11.42%, respectively. 4. A fluctuation phenomenon of expiratory gas concentration was observed only in IC. Mass spectrometry did not show this phenomenon. This phenomenon seems to be derived from the IC machine itself.

Abstract
1. Biliary atresia (BA), as a common disease in Japan, and cystic fibrosis (CF), as an extremely uncommon disease in Japan, were selected to assess the clinical significance of measurement of energy expenditure (EE). 2. Energy expenditure was significantly higher in children with BA than in normal children. 3. Measurement of EE in BA lead to clues to resolving its mechanism by novel assessment of interleukin-6 and leptin. 4. Energy expenditure in children with CF is also higher, but this has been addressed by nutritional intervention with additional calories. 5. Individualization of EE measurement is necessary in the analysis of pathological mechanisms and nutritional management of patients with both common and uncommon diseases.

Abstract
The purpose of this study was to evaluate the priming effect of 2-hydroxyethylmetaclirate (HEMA) following acid treatment on resin bonding to prototype Er:YAG laser-irradiated dentine. Extracted bovine dentine following laser irradiation was acid treated by aqueous solution of 10% citric acid (10-0) or 10% citric acid/3% ferric chloride (10-3), and additionally treated with 35% HEMA. Pre-treated dentines were bonded to the polymethyl-methacrylate (PMMA) rod with 4-META/MMA-TBB resin (Super Bond C & B) and miniaturized dumbbell-shaped bonded specimens were prepared. These specimens profiled for tensile bond testing and fractured surfaces were observed by scanning electron microscopy (SEM). Cross-sections of resin-dentine interface were also examined. The HEMA treatment following acid conditioned by 10-3 or 10-0 for both laser-irradiated and non-irradiated dentines was significantly higher than that without HEMA treatment. SEM view of a fractured specimen showed some cohesive failure in cured resin, but almost all of the fractured surface shows boundary failure between the penetrated resin and underlying dentine. A cross-sectional view of the interface showed a very thick hybrid layer between the hybridized dentine and underlying dentine. It was concluded that HEMA treatment following acid conditioning provided a slightly higher bond strength for both the Er:YAG laser-irradiated and non-irradiated dentines. However, the bond strength of Er:YAG laser irradiated dentine was significantly lower than that of the non-irradiated dentine.

Abstract
BACKGROUND The trimethadione (TMO) tolerance test was performed to evaluate its usefulness in the assessment of hepatic functional reserve in patients with biliary atresia. METHOD Nineteen patients with biliary atresia after hepatic portoenterostomy (age range: 2 months to 25 years; sex: 6 males and 13 females) were studied. The study was performed in the morning after a 12-h fast. TMO was given orally, at a dose of 4 mg/kg, with 5 mL of 5% glucose 2 h before breakfast. Blood samples (0.5 mL) were collected to determine serum TMO and dimethadione (DMO), a metabolite of TMO, levels 4 h after the administration of TMO. TMO and DMO were measured by a gas-liquid chromatographic method. RESULTS A higher total bilirubin level (over 1 mg/dL) in patients with jaundice was reflected in the smaller serum DMO/TMO ratio 4 h after the oral administration of TMO. In addition, these patients with total bilirubin levels of 1 mg/dL or less had a significantly lower DMO/TMO ratio than the control group (healthy subjects). The serum DMO/TMO ratio showed a close correlation with the Child-Pugh score, which is used for overall evaluation of severity of cirrhosis and Mayo risk scores for primary biliary cirrhosis in adults (0.856, P < 0.01 and 0.788, P < 0.01, respectively). The TMO tolerance test shows the benefit of performing a relatively early test of dynamic liver function to evaluate hepatic functional reserve in pre- and post-operative biliary atresia patients.

Abstract
Thymic epithelial cells, which create a three-dimensionally organized meshwork structure peculiar to the thymus, develop from simple epithelia of the third pharyngeal pouch and cleft during organogenesis. We comparatively investigated the thymus anlages of normal and nude mice by immunohistochemical analysis with regard to epithelial organization and distribution of hematopoietic progenitor cells at early stages of organogenesis. Our results show that development of the mouse thymus anlage at early stages can be subdivided into at least two stages by the differences in epithelial organization, i.e. stratified epithelial stage on embryonic day (Ed) 11 and clustered epithelial stage on Ed12. At the former stage, hematopoietic progenitor cells are accumulated in the mesenchymal layer of the thymus anlage, and at the latter stage progenitor cells enter the epithelial cluster and proliferate. In nude mice, hematopoietic progenitor cells are found in the mesenchymal layer on Ed11.5, but they are not observed among epithelial cells on Ed12, even though epithelial cells form a cluster structure. The present results suggest that aberrant development of the nude mouse thymus anlage occurs at the clustered epithelial stage and that epithelial cells of the nude anlage lack the ability to induce the entrance of hematopoietic progenitor cells into the epithelial cluster.

Abstract
A case of carcinosarcoma of the urinary bladder in a 2-year-old girl is reported. The tumor, measuring 34 x 20 x 18 mm, was located in the peri-trigone area of the urinary bladder with polypoid features. Histologic examination revealed transitional cell carcinoma at the tumor surface with downward invasion. Concurrently, a sarcomatous area was found beneath the carcinoma, with these two different malignant components sharing on apparent transition without distinct boundaries. Sarcomatous components included immature round cells focally showing rhabdoid features. No rhabdomyomatous component was observed. Immunohistochemistry disclosed vimentin and cytokeratin-double positive cells at the transposition between carcinoma and sarcomatous components. In addition, ultrastructural analysis revealed that the epithelial cells had a distinct junctional complex, and the sarcomatous cells occasionally had a meshwork of cytoplasmic intermediate filaments, indicating bidirectional cytodifferentiation to epithelial and mesenchymal elements. The extremely young age at which this case of carcinosarcoma occurred suggests that the tumor may be of mesodermal stem cell origin.

Abstract
The authors propose a new surgical approach for neonates and infants with hydrometrocolpos caused by double vagina and imperforate hemivagina. Usually for these patients, laparotomy is a common approach used to decompress the obstructed hemivagina. The authors compared the characteristics of three options used to relieve obstruction of the hemivagina using endoscopic, transvaginal, and laparotomy approaches. An endoscopic septotomy (colposcopic approach) using the Storz neonatal resectoscope is less invasive and less expensive than other methods. We emphasize that endoscopic septotomy is a feasible surgical method to relieve the obstructive symptoms related to imperforate hemivagina.

Abstract
Lympho-stromal interactions in the thymus crucially de- termine the fate of developing T cells. Epithelial cells, inter- digitating reticular cells, macrophages and fibroblasts all play a role in the shaping of the T cell repertoire. Recently published evidence shows that lympho-stromal interaction acts bi-directional. Developing T cell themselves, at different stages of differentiation, control the microarchitecture of thymic microenvironments, a phenomenon designated as 'crosstalk'. This paper reviews experiments showing that developing T cells crosstalk to different thymic epithelial cells in a stepwise fashion. In this way, correctly organized thymic microenvironments guarantee normal thymopoiesis.

Abstract
Previously, we have shown that embryonic day 12 thymus anlage cultured alone cannot develop into the mature organ but degenerates. In the present study, we investigated the cause of this insufficient organogenesis of embryonic day 12 thymus anlage in organ culture. We cocultured embryonic day 12 thymus anlages with various cell lines as pellets formed by centrifugation. In coculture with fibroblastic cell lines, but not with thymic epithelial cell lines, embryonic day 12 thymus anlages developed to support full T cell differentiation, and expressed mature stromal cell markers, Ia and Kb. By pellet culture of thymus anlages and fibroblastic cell lines transfected with a beta-galactosidase expression vector, we analyzed the distribution of added fibroblastic cells in pellets. The added fibroblastic cells constituted neither thymic capsule nor septa but disappeared after about 2 weeks in culture. Moreover, immunohistochemical studies indicated that added fibroblastic cells were adjacent to mesenchymal cells of thymus anlage. Our results strongly suggest that added fibroblastic cells support the development of the thymus anlage through interaction with its mesenchymal cells.

In SCID-hu mice, passive transfer of a humanized antibody prevents infection and atrophic change of medulla in human thymic implant due to intravenous inoculation of primary HIV-1 isolate.

Abstract
Using SCID-hu mice, it was tested whether humanized mAb Rmu5.5 could prevent infection by HIV-1 i.v. inoculation. The Ab that recognizes the IHIGPGRAFYT motif in the principal neutralizing determinant (PND) of HIV(MN), as well as the original mouse mAb mu5.5, neutralized HIV(MN) with high activity. Seven primary field isolates from Japanese hemophiliacs seropositive for HIV-1 clade B were compared for their reactivities to Rmu5.5. Rmu5.5 was effective, particularly against the viruses that matched amino acid sequences of the PND region of HIV-1, and it completely neutralized primary isolates. Moreover, the passive transfer of the Ab elicited protection against challenge by the primary isolates in SCID-hu or hu-PBL-SCID mice after i.v. inoculation with the virus by both quantitative PCR and PBMC-based virus isolation in vitro. Further, inoculation with the Ab also prevented the atrophic change in the medulla of the thymic transplant that was induced by i.v. inoculation of the virus. Thus, the humanized neutralizing Ab Rmu5.5 appears to protect SCID-hu mice from infection by primary field isolates.

Abstract
Human fetal thymus/liver engrafted SCID mice were constructed and studied for its susceptibility to HIVBRU infection by i.v. inoculation which seemed to represent an appropriate route of HIV infection in vivo. By the i.v. inoculation of HIV, the medulla in the engrafted thymus narrowed significantly when compared with that of the human thymic implant from virus-uninoculated mice. Further, immunohistochemical staining indicated the presence of HIV antigen predominantly in thymic epithelial cells in medulla of the engrafted thymus. Polymerase chain reaction (PCR) assays resulted in amplifications of HIV genome in the implanted grafts as well as in lymph nodes and PBMC. The virus infections to the implants were confirmed biologically by coculturing with PHA-stimulated human PBMC and the graft cells from the HIV-inoculated SCID-hu mice. Thus, the i.v. inoculation of HIV into Thy/Liv SCID-hu mice induce narrowing of medulla of the engrafted thymus and may become an efficient and useful tool for screening candidate anti-HIV agents.
