A Super-Aged Case with Marked Hyponatremia Reaching 98 mEq/L;Clinical Implications of Low Serum Sodium

A 79-year-old man, an in-patient at a long-term hospital suffers from Alzheimer dementia and thyroid hypofunction. Recently, he had also suffered from pneumonia followed by impaired consciousness and referred to our hospital for further examination. At the time of admission, the level of consciousness was JCS III-200 and other vital signs were normal. He had no edema on his limbs but had dry skin. According to chest CT, we detected pneumonia. Based on the laboratory data on admission, we detected low osmolality of 206 mOsm/kg of water and serum Na 98 mEq/L, beside urinary Na 54.1 mEq/L. We confirmed severe hyponatremia of hypersecretion type. Fluid replacement therapy was started mainly with Ringer’s solution which is similar to extracellular fluid. We diagnosed it as SIADH induced by adrenal crisis based on the significant lower serum Na value and low blood sugar. Consequently, the patient was administered Hydrocortisone and Fludrocortisone acetate. On the 14th day, serum Na level improved from 98 mEq/L to 140 mEq/L. After daily monitoring of serum Na and urinary Na, administration of fludrocortisone acetate was terminated. The patient was discharged on 25th day, since serum Na was stabilized with oral administration of hydrocortisone and oral salt supplement. This case report shows that adrenal crisis can be triggered by pneumonia. In cases of impaired consciousness, if hyponatremia and hypoglycemia are observed, we may have to suspect the possibility of adrenal crisis. Therefore, urinary biochemical examination is an important part of the laboratory tests.

Use of Artificial Dermis and Cultured Epithelial Autograft for Extensive Deep Dermal Burns —A Case Report

In the treatment of extensive burns, cultured epithelial autograph (CEA) became available commercially in Japan from 2009. Based on the 6 years multicenter surveillance data on using CEA for extensive burns, it is reported that using 6:1 split thickness skin graft together with CEA is successful after wound bed preparation for extensive deep dermal burn or patients with deep burn [1].

Unexpectedly Good Neurological Outcome after Prolonged Cardiac Arrest

Backgoround: Generally, neurological outcome of patients who have achieved return of spontaneous circulations (ROSC) with abnormal blood tests date and some severe organ complications is extremely poor. Because we experienced a case of good neurological outcome using two different types of extracorporeal membrane oxygenation (ECMO) in spite of prolonged cardiac arrest, we reported this case and reviewed the literature. Case presentation: A 36-year-old male suddenly collapsed at bar after drinking. Initial ECG showed ventricular fibrillation (VF) and subsequently underwent advanced cardiovascular life support. On admission, the ECG still showed VF, but pupillary light reflex was faintly present. Then, veno-arterial extracorporeal membrane oxygenation (VA-ECMO) support was established 54 minutes after collapse. Blood tests showed lactate was 15.8 mmol/l and NH3 of 251 μg/dl. To improve respiratory function after cardiogenic shock, we changed to veno-venous ECMO (VV-ECMO) and removed superabundant fluid using continuous hemodiafiltration. Patient was discharged on day-26 after a full functional recovery. Conclusion: In severe respiratory disorder, it would be more effective to change to VV-ECMO after recovering from cardiogenic shock while removing superabundant fluid using continuous hemodiafiltration. In predicting the neurological outcome of a post cardiac arrest patient, the presence of a pupillary light reflex may be more significant than NH3 and lactate.

Three Cases of Severe Stercoral Colitis

Stercoral colitis is the inflammation of the colonic wall caused by fecal impaction. When a patient with a history of chronic constipation visits the Emergency Center with diffuse abdominal pain, sepsis and or rectal bleeding, clinicians should consider the possibility of stercoral colorectal perforation. An accurate diagnosis on a computed tomography (CT) scan (for fecal impaction, intra-abdominal feces, intraperitoneal free air, stranding of the peri-colonic fat in the segment, presence of extraluminal bubbles of gas) may facilitate early surgical intervention and improve the patient’s prognosis based on our clinical experience dealing with three patients who had stercoral colitis.

Serum Albumin Levels in Emergency Patients with Low BMI

A low body mass index (BMI) is often associated with low nutritional status and adverse health outcomes. While the BMI is used in describing “thinness” meaning cachexia, serum albumin levels were also used in assessing patient’s nutritional conditions. Object: A retrospective study was conducted to determine whether the extremes of BMI and/or cachexia increased the morbidity and mortality in our critical emergency department. Methods: A hundred and five cases with low BMI (≤18.5 kg/m2) were chosen from the patients who were admitted to our critical emergency department from Sept 2013 to Aug 2016. The relationship between serum albumin levels on admission and prognosis were analyzed. Results: No significant correlations were observed between body mass index and albumin levels in thin patients. Lower levels of serum albumin (p Conclusions: Even with low BMI, if the albumin value was 3.3 g/dL or more, the prognosis was good in our emergency department. Estimation of albumin level on admission is not only a simple and objective way to assess the nutritional status but also a useful outcome predictor of critically ill patients coming to emergency centers.

To Investigate the Effect of Using Ethanol Containing Wipes in Collecting Blood for the Measurement of Alcohol Concentration

This study was aimed to establish whether the skin preparation using ethanol-containing skin antiseptics causes ethanol contamination through blood collection. Venous blood was collected from 40 healthy volunteers according to the national guidelines for blood sampling, with four sequential procedures as follows: 1) collecting blood immediately (within 5 seconds) after cleaning the skin with an individually packaged type of ethanol-containing wipe, 2) collecting blood 1 minute after cleaning the skin with an individually packaged type of ethanol-containing wipe, 3) collecting immediately (within 5 seconds) after cleaning the skin with a traditional cleaning method (thoroughly ethanol-impregnated wipe, and 4) collecting 1 minute after cleaning the skin with a traditional cleaning method. Each sequential procedure was performed with and without the ethanol-containing wipe used for skin cleaning on the puncture site on their right and left arms at the time the needle was withdrawn, respectively. The collected specimens were subjected to the determination of ethanol by using headspace gas chromatography-mass spectrometry. In every 80 blood specimens obtained from 40 participants, ethanol was undetectable (<0.001 mg/mL). This study demonstrates that disinfection using ethanol-containing skin antiseptics is unlikely to cause ethanol contamination through blood collection regardless of skin preparation technique according to the guidelines for blood sampling. This may have implications in forensic science.
