RESUMO
BACKGROUND: FOLFOX therapy, a standard treatment for colorectal cancer (CRC), causes a rare, but serious adverse event, hyperammonemia. However, the risk factors of hyperammonemia remain unknown. METHODS: We examined 74 patients who received mFOLFOX6 therapy with or without biologics for CRC between April 2013 and March 2018 in Yaizu City Hospital. Clinicopathological factors were retrospectively reviewed in association with hyperammonemia, and risk factors of hyperammonemia during mFOLFOX6 therapy were analyzed in 32 patients with the available data. RESULTS: Seven patients developed hyperammonemia, with onset exclusively on day 2 or 3 in the first cycle of therapy. They were treated with branched chain amino acid administration and hydration; however, one patient with stage G4 chronic kidney disease (CKD) died. By multivariate analysis, estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m2 was independently associated with hyperammonemia during FOLFOX therapy (odds ratio: 9.0, p = 0.040). CONCLUSIONS: Reduced eGFR is considered a risk factor of developing hyperammonemia during FOLFOX therapy. Serum ammonia levels should be monitored especially during the first cycle of FOLFOX therapy in patients with CKD stage G3 or higher.
RESUMO
71-year-old woman was pointed out to have an asymptomatic mediastinal tumor. Chest computed tomography(CT) showed a well-demarcated mass measuring 7 cm in diameter in the anterior mediastinum. We resected the mass through a median sternotomy. The tumor had a clear margin without invasion to the surrounding tissue and did not show continuity with the cervical thyroid gland. Histopathologically, the tumor was diagnosed as follicular thyroid carcinoma with capsular invasion. This is an exceptionally rare case.

Following chest or abdominal injury, acute blurring of vision occurs without direct eye injury. This disease is known as Purtscher's retinopathy. A 74-year-old man suffered blunt chest injury by air bag inflation at traffic accident. Next morning, he suddenly complained of visual abnormality. An ophthalmoscopy revealed multiple cotton-wool exudation and retinal edema. He was diagnosed as Purtscher's retinopathy. The symptoms of soft exudation and retinal edema gradually resolved. The visual acuity gradually improved, but not reached to the previous level. We must be aware of this retinopathy, since this is rare but sometimes sight-threatening condition.

A 63-year-old woman was admitted with abdominal pain two months after laparoscopic abdominoperineal resection for rectal cancer. Computed tomography revealed dilated small intestine had passed through a defect between the lifted sigmoid colon and abdominal wall. She was diagnosed with small bowel obstruction without strangulation due to internal hernia and managed nonoperatively based on her wish. Recurrence of intestinal obstruction occurred for which curative surgery was performed laparoscopically. The herniated intestine was restored to the normal position, and the hernia orifice was closed using barbed suture, on laparoscopic management. Internal hernia is a rare complication after colostomy that requires surgical management. Although laparoscopic approach on re-operation is difficult, laparoscopic surgery may be suitable for patients with IHAC in terms of required less use of adhesiolysis.
RESUMO
BACKGROUND/AIMS: Severity of inflammation may be a risk factor for negative outcome in non-operative therapy of appendicitis. However, optimal screening test for predicting the pathological severity of appendicitis has not been established. METHODOLOGY: 632 consecutive patients who underwent appendectomy at a single institute were retrospectively reviewed. Clinical parameters are compared among the three pathological grades: simple (G1), gangrenous (G2), and perforated appendicitis (G3). The diagnostic power of inflammatory markers (WBC count and CRP concentration) in discriminating the advanced appendicitis from the milder one was evaluated. RESULTS: CRP concentration was well correlated with the severity of appendicitis (p>0.0001), while WBC count showed only slight increase in advanced pathology (G1 vs. G2-G3). In receiver operating characteristic (ROC) curve analysis, the area under the curve (AUC) was remarkably higher in CRP (AUC 0.809) compared with that in WBC count (AUC 0.617), suggesting that CRP is a more sensitive test in discriminating the pathological severity of appendicitis. Multivariate analysis confirmed that CRP concentration >6.2mg/dL (OR: 5.12; 95% CI: 2.17-12.7) and diameter >12mm (OR: 4.33; 95% CI: 1.98-9.90) were strong predictive factors for advanced appendicitis. CONCLUSIONS: CRP concentration may be a potent objective predictor of pathological severity in appendicitis. Combination with the other diagnostic modalities may improve the diagnostic accuracy in predicting the severity of appendicitis.

RATIONALE: Hormone therapies, particularly those targeting estrogen and its receptors, are a key treatment modality for patients with estrogen receptor (ER)-positive breast or ovarian cancer. Some gastric cancers (GCs) express ERs, and preclinical studies suggest the potential of estrogen-targeting hormone therapy on GC; however, the clinical relevance of this hormone therapy on GC treatment has not been well elucidated. PATIENT CONCERNS: An 80-year-old female was admitted to our department with hypogastric pain and vomiting. Computed tomography demonstrated small bowel obstruction, and laparotomy after bowel decompression revealed peritoneal dissemination consisting of a poorly-differentiated adenocarcinoma. Intestinal bypass between the ileum and transverse colon was performed. DIAGNOSES: The tumor was ER- and mammaglobin-positive, indicating that it originated from a breast cancer. Diagnostic imaging revealed no evidence of breast cancer; however, right axillary ER- and mammaglobin-positive lymphadenopathy was found. INTERVENTIONS: The patient received hormone therapy using letrozole based on a clinical diagnosis of occult breast cancer with peritoneal dissemination and right axillary lymph node metastasis. OUTCOMES: The patient remained disease free until 37âmonths but deceased at 53âmonths from the onset of disease. An autopsy revealed no tumor cells in the right breast tissue; however, there was a massive invasion of cancer cells in the stomach. LESSONS: A patient with ER positive GC with peritoneal dissemination and right axillary lymph node metastasis presented remarkable response to letrozole. The long-term survival obtained using letrozole for a patient with GC with distant metastasis suggests the potential of estrogen targeting hormone therapies for GC.

Central venous port (CVP) is a widely used totally implantable venous access device. Recognition of risks associated with CVP-related complications is clinically important for safe, reliable, and long-term intravenous access. We therefore investigated factors associated with CVP infection and evulsion, including the device type. A total of 308 consecutive patients with initial CVP implantation between January 2011 and December 2017 were retrospectively reviewed, and the association of clinical features with CVP-related complications were analyzed. Intraoperative and postoperative complications occurred in 11 (3.6%) and 39 (12.7%) patients, respectively. The overall rate of CVP availability at six months was 91.4%. Malignancy and 2-Methacryloyloxyethyl phosphorylcholine (MPC) polymer-coated catheter use were negatively associated with the incidence of CVP infections. Accordingly, malignancy and MPC polymer-coated catheter use were independent predictors for lower CVP evulsion rate (odds ratio, 0.23 and 0.18, respectively). Furthermore, both factors were significantly associated with longer CVP availability (hazard ratio, 0.24 and 0.27, respectively). This retrospective study identified factors associated with CVP-related complications and long-term CVP availability. Notably, MPC polymer-coated catheter use was significantly associated with a lower rate of CVP infection and longer CVP availability, suggesting the preventive effect of MPC coating on CVP infection.

Motivated by developments in information technology, recording personal parameters with health devices is effective in health promotion. Today's indoor individual lifestyles often involve using electrical appliances. We developed a health support system combined with wireless electricity monitoring and investigated whether electricity use is associated with residents' vital data and lifestyles. We recruited 116 participants in February 2013. Their vital and electricity use data were collected daily. They completed a self-administered questionnaire. Among participants living alone, electricity from 20 February to 11 March 2013 was negatively associated with high-density lipoprotein (HDL) (P = 0.008) and positively associated with low-density lipoprotein (LDL) (P = 0.007) and neutral fat (P = 0.020) levels. Among all participants, electricity use was negatively associated with vegetable intake (P = 0.044) and step count (P = 0.040). Temperature sensitivity in winter was negatively associated with the LDL/HDL ratio for both men and women. For men, temperature sensitivity in winter was negatively related with alcohol intake; for women, it was positively related to body fat percentage and abdominal circumference and negatively correlated to vegetable intake. Temperature sensitivity in summer was positively associated with vegetable intake for men and women. In conclusion, electricity use was related to vital data and lifestyles and influenced by temperature.

BACKGROUND: Histoplasmosis is considered a fairly rare imported mycosis in Japan. Here we report a case of histoplasmosis describing the preoperative findings, histopathological findings, supposed infection route, and appropriate treatment, including the postoperative management. CASE PRESENTATION: A healthy 65-year-old man was found at routine medical check-up to have an abnormal opacity on chest radiography. A chest computed tomography (CT) scan showed a nodular lesion in the posterior basal segment of the right lung, as well as two smaller nodules in the same lobe. This was highly suggestive of primary lung cancer with pulmonary metastases in the same lobe. We thus performed a right lower lobectomy with hilar and mediastinal lymph node dissection via thoracotomy. The lesions were diagnosed as pulmonary histoplasmosis on histopathology. At 6-month follow-up examination, the patient was free from fungal infection without any postoperative medication. CONCLUSIONS: We describe a patient with pulmonary histoplasmosis diagnosed following surgical lobectomy. The possibility of pulmonary histoplasmosis should be considered in the differential diagnosis of pulmonary nodular lesions.
RESUMO
BACKGROUND: Although sepsis after surgery for colorectal perforation frequently results in severe coagulation disorders and consequent death of the patient, the correlation between coagulation abnormalities and postoperative mortality of colorectal perforation has not been clarified. METHODS: The medical records of 101 consecutive patients receiving surgery for colorectal perforations between January 1994 and July 2006 were retrospectively reviewed. The abnormalities of preoperative laboratory data reflecting coagulation disorders and other possible risk factors were analyzed by univariate and multivariate analysis. RESULTS: Prolonged prothrombin time and activated partial thromboplastin time significantly correlated with a poor prognosis (both P < 0.001). Among the several risk factors analyzed, only the presence of coagulation disorders was an independent predictive factor of postoperative mortality. CONCLUSIONS: Prolonged prothrombin time and activated partial thromboplastin time are useful prognostic factors for predicting the surgical outcome for patients with colorectal perforation.

We isolated GAGs from the inedible parts; head, skin, internal organs, fins, scales and spine, of atlantic mackerel (Scomber scombrus), japanese jack mackerel (Trachurus japonicus), pacific bluefin tuna (Thunnus orientalis), yellowfin sole (Limanda aspera), broadbanded thornyhead (Sebastolobus macrochir), golden threadfin bream (Nemipterus virgatus), and nile tilapia (Oreochromis niloticus). We also investigated deep-sea fish, eelpouts (Bothrocara hollandi, Lycodes toyamensis, and Lycodes nakamurae), rough snailfish (Careproctus trachysoma), and squids (Watasenia scintillans, Enoploteuthis chunii, and Berryteuthis magister). Enzymatic digestion of the GAGs enabled a compositional analysis of CS, DS, and HA including the sulfation patterns of CS and DS, as well as the amount of each GAG. The molecular weights and distributions of these GAGs were also examined. The amounts of GAGs contained in the tissues and CS/DS ratios differed remarkably among the fish. The dorsal fin of the yellowfin sole contained more than 1300mg of CS-DS per 100g of defatted-dry tissue. Although the fish generally contained A-type rich CS-DS, bottom fish and deep-sea fish often possessed C-type CS-DS in larger ratios. Squid characteristically had E-type CS-DS which was normally less common in fish except in cartilaginous fish. These analytical results had no relation to the biological classification.

BACKGROUND: Acute appendicitis has been reported to be managed with non-operative therapy at relatively high successful rate. However, risk factors for negative outcome have not been established. METHOD: Three hundred eighty consecutive patients who underwent initial therapy for suspected appendicitis were reviewed. They were divided into three groups: operation group, the group successfully managed with non-operative therapy (success group), and the group required surgical conversion (failure group). Preoperative clinical data were compared among the groups and risk factors for negative outcomes were investigated. RESULT: Thirteen patients were excluded due to contraindication for non-operative therapy. Of the remaining 367 patients, 143 patients (39.0%) were primarily treated with surgery, and 224 patients (61.0%) were initially managed with antibiotics. Among the 224 patients, 91 patients (40.6%) were refractory to antibiotics and converted to surgery after more than 24 h usage of antibiotics. Multivariate analysis revealed that elevated C-reactive protein (CRP) level (>4 mg/dL) and presence of appendicolith were significant risk factors for conversion. Morbidity rate showed no significant difference between the operative and failure groups. CONCLUSION: Elevated CRP concentration and appendicolith may predict the negative outcome in non-operative management. However, immediate appendectomy can possibly be avoided at least 24 h without increasing morbidity under the usage of antibiotics.
