A 7-year-old neutered male, domestic shorthair cat presented anorexia and lethargy. The complete blood cell count revealed severe non-regenerative anemia, lymphocytic leukocytosis, neutropenia, and thrombocytopenia. On the peripheral blood smear examination, medium to large lymphoblastic cells with moderate amounts of basophilic cytoplasm were observed in up to 70% of peripheral leukocytes. Feline leukemia and immunodeficiency viruses were not detected using a commercial diagnostic kit. While splenomegaly and blunt margins of the caudoventral liver were observed in abdominal radiography, changes in the intra-abdominal lymph nodes were not remarkable. Ultimately, flow cytometric immunophenotyping from the peripheral blood revealed a negative for B-cell markers (CD21-/CD79a-) and T-cell markers (CD3-/CD4-/CD5-/CD8-). Based on the hematological examination and the immunophenotyping assay, the cat was diagnosed with non-B, non-T acute lymphoblastic leukemia. Here, we report a rare case of non-B, non-T acute lymphoblastic leukemia to raise awareness and provide information on clinical symptoms and laboratory test and immunophenotyping analysis results.

Purpose: The objective of this study was to develop a new scoring tool that is comprehensively applicable and predicts fatality within 24 h of intoxication. Methods: This was a cohort study conducted in two emergency medical centers from 2011 to 2012. We identified factors associated with severe/fatality. Through a discriminant analysis, we devised the aBIG (age, Base deficit, Infection, and Glasgow coma scale) score. To compare the ability of aBIG to predict intoxication severity with that of previous scoring systems such as APACHE II, MODS, SAPS IIe, and SOFA, we determined the receiver operating characteristic curves of each variable in predicting severe-to-fatal toxicity. Results: Compared with the mild/moderate toxicity group (n=211), the severe/fatal group (n=143) had higher incidences of metabolic acidosis, infection, serious mental change, QTc prolongation and hepato-renal failure. Age, base deficit, infection-WBC count, and Glasgow Coma Scale were independently associated with severe/fatal poisoning. These variables were combined into the poisoning "aBIG" score [$0.28{\times}$Age group+$0.38{\times}WBC$ count/$10^3+0.52{\times}$Base deficit+$0.64{\times}$(15-GCS)], which were each calculated to have an area under the curve of 0.904 (95% confidence interval: 0.868-0.933). The aBIG poisoning score had an equivalent level of severity predictability as APACHE II and a superior than MODS, SOFA, and SAPS IIe. Conclusion: We developed a simplified scoring system using the four variables of age, base deficit, infected leukocytosis, and GCS. The poisoning aBIG score was a simple method that could be performed rapidly on admission to evaluate severity of illness and predict fatal severity in patients with acute intoxications.

The activation of protooncogenes or the inactivation of their gene products may be a specific and effective functional study for human neoplasia. To examine this possibility, we have used the tetracycline regulatory system to generate transgenic mice that conditionally express the HccR-2 protooncogene in vivo. The new human cervical cancer protooncogene (HccR-2) was detected from cervical cancer cell line. To elucidate its biological functions, we generated transgenic mice that expressed the HccR-2 gene. The sustained expression of the HccR-2 transgene culminated chronic neutrophilic leukemia (CNL). CNL is a rare chronic myeloproliferative disorder that presents as a sustained, mature neutrophilic leukocytosis with few or no circulating immature granulocytes, the absence of peripheral blood monocytosis, basophilia, or eosinophilia, and infiltration of neutrophils at the liver, spleen and kidney. Mice expressing the HccR-2 and tetracycline-transactivating protein (tTa) transgene were found to have altered myeloid development that was characterized by increased percentages of mature neutrophil and band form neutrophil in the peripheral blood, liver and spleen. Activation of the transgene causes CNL. In our model, expression of HccR-2 transgene mice was similar in many respects to the human CNL. This model will be valuable not only for investigating the biological properties of the HccR-2 and other protooncogenes in vivo but also for analyzing the mechanism involved in the progression of CNL.

Objective: To report a fatal case of Multidrug-resistant Acinetobacter baumannii (MDR-AB) in a patient with interstitial lung disease (ILD) on high-dose glucocorticoids. Case Summary: A 66-year-old man with a history of coniosis was transferred to the hospital with progressive cough and sputum production. This patient has been diagnosed with pneumonia and ILD on admission, requires antimicrobial therapy and systemic immunosuppressants. He received high dose of methylprednisolone and cyclophosphamide for ILD as well as ceftriaxone and azithromycin for pneumonia. On day 7 in the intensive care units (ICUs), patient had fever and leukocytosis, thus antimicrobials were switched to piperacillin. After 13 days in the ICU, Acinetobacter baumannii and methicillin-resistant Staphylococcus aureus (MRSA) were isolated on transtracheal aspirate (TTA) and meropenem was initiated. However, it was revealed a multidrug-resistant Acinetobacter baumannii (MDR-AB) species, resistant to carbapenem. Patient was administered colistin but expired due to septic shock on day 84. Discussion: Systemic immunosuppressive therapy can result in infections that may compromise patient's survival. MDR-AB has emerged as a serious cause of nosocomial infections in immunocompromised patients. MDR-AB is resistant to most standard antimicrobials and therapeutic options are limited. Conclusion: We report our recent experience with a fatal MDR-AB pneumonia in a patient with ILD, who had to be treated with high dose glucocorticoids and immunosuppressnts.

The aim of this study is to evaluate the clinical outcome. Between January 1,2002 to September 30, 2002, we prospectively and retrospectively recruited III hospitalized patients who received Enteral Nutrition (EN group n = 52) and Total Parenteral Nutrition (TPNgroup n = 59) for more than seven days. The factors of clinical outcomes are costs, incidences of infection, lengths of hospital stay, and changes in weight. The characteristics of patients were investigated, which included nutritional status, disease severity CAP ACHE III score) and hypermetabolic severity Chypermetabolic score). Hypermeta-bolic scores were determined by high fever (> $38^{\circ}C$), rapid breathing (> 30 breaths/min) , rapid pulse rate (> 100 beats/min), leukocytosis (WBC > 12000 $mm^{3}$), leukocytopenia (WBC > 3000 $mm^{3}$), status of infection, inflammatory bowel disease, surgery and trauma. There was a positive correlation between hypermetabolic score and length of hospital stay (ICU), medical cost, weight loss, antibiotics adjusted by age while APACHEIII score did not show correlation to clinical outcome. Medical cost was higher by $18.2\%$ in the TPN group than the EN group. In conclusion, there was a strong negative correlation between the clinical outcome (cost, incidence of infection, hospital stay) and hypermetabolic score. Higher metabolic stress caused more malnutrition and complications. For nutritional management of patients with malnutrition, multiple factors, including nutritional assessment, and evaluation of hypermetabolic severity are needed to provide nutritional support for critically ill patients.

Purpose: Although procalcitonin (PCT) level is useful for the diagnosis of neonatal sepsis, PCT reliability is inconsistent because of the varied conditions encountered in neonatal intensive care units. This study aimed to investigate PCT levels and factors influencing increased PCT levelin newborns without bacterial infection during the first week of life. Methods: In newborns hospitalized between March 2013 and October 2015, PCT levels were measured on the first, third, and seventh days after birth. Newborns with proven bacterial (blood culture positive for bacteria) or suspicious infection (presence of C-reactive protein expression or leukocytosis/leukopenia) were excluded. Various neonatal conditions were analyzed to identify the factors influencing increased PCT level. Results: Among 292 newborns with a gestational age of $35.2{\pm}3.0$ weeks and a birth weight of $2,428{\pm}643g$, preterm newborns (n=212) had higher PCT levels than term newborns (n=80). Of the newborns, 7.9% had increased PCT level (23 of 292) on the firstday; 28.3% (81 of 286), on the third day; and 3.3% (7 of 121), on the seventh day after birth. The increased PCT level was significantly associated with prenatal disuse of antibiotics (P=0.004) and surfactant administration (P<0.001) on the first day after birth, postnatal use of antibiotics (P=0.001) and ventilator application (P=0.001) on the third day after birth, and very low birth weight (P=0.042) on the seventh day after birth. Conclusion: In newborns without bacterial infection, increased PCT level was significantly associated with lower gestational age and respiratory difficulty during the first week of life. Further studies are needed for clinical applications.
