Suspected Gastroparesis With Concurrent Gastroesophageal Reflux Disease Induced by Low-Dose Liraglutide.

A 74-year-old woman with type 2 diabetes mellitus presented with nausea and abdomen distension. Four days prior, liraglutide 0.6 mg had been commenced. An abdominal computed tomography scan revealed gastric dilatation without mechanical obstruction which clinically suggested gastroparesis (GP). Her symptoms resolved after liraglutide discontinuation. A gastroscopy revealed reflux esophagitis. Taken together, GP may have developed along with reflux esophagitis due to liraglutide administration. Liraglutide's action inhibits gastric motility. Physicians should be cognizant of the side effects of GLP-1 agonists even in low dose in patients who have gastric emptying symptoms suggesting GP.

Successful salvage of torsion testis by means of intraoperative indocyanine green fluorescence imaging.

BACKGROUND: Testicular torsion (TT) is common surgical emergency that requires early diagnosis and immediate intervention within 6 h since its onset to salvage the testis. However, the decision was made only by the surgeon's experience whether it has to be resected or not. Recently, indocyanine green (ICG) has become an excellent tool to identify biliary and vascular anatomy, and assess perfusion abnormalities in tissues. In this case report, we successfully salvaged the twisted testis, since the testicular blood perfusion was confirmed by means of intraoperative ICG (IICG) fluorescence imaging. CASE PRESENTATION: A 14-year-old healthy male patient presented due to acute left testicular pain. The patient was diagnosed with TT and had immediate surgery. Macroscopically, the testis had stagnant blood flow and appeared to be dark colored. After manual detorsion, the testis remained cyanotic and with macroscopically poor blood flow. ICG angiography was performed under near-infrared light by laparoscopic camera to assess the perfusion of the affected testicle. An excellent ICG signal appeared after 45 s in the testis, and decision was made to be preserved. Therefore, left orchidopexy was performed to complete the operation. The patient had a good postoperative course and was discharged the day after surgery. Six months later, the testis did not show any shrinkage, and both sides of the testis showed the same size without any consequences. CONCLUSION: The blood flow in the testis was visually confirmed during the IICG fluorescence method. ICG fluorescence imaging may become an effective alternative to evaluate whether a testis can be preserved following TT.

A rare cause of acute kidney injury with chronic myelomonocytic leukemia.

An 80-year-old man with myelodysplastic syndrome developed acute kidney injury (AKI) and peripheral blood monocyte-dominant leukocytosis. Glomerular disease was suspected from urinalysis, which showed proteinuria and microscopic hematuria with red cell casts. Eventually, he died of respiratory failure, after which a postmortem was performed. In the glomeruli, the extracapillary space was filled with numerous mononuclear cells and erythrocytes. At first interpretation, the glomerular findings appeared to represent cellular crescents. However, immunostaining revealed that the extracapillary mononuclear cells were in fact leukemic cells. Furthermore, tubular injury due to marked accumulation of lysozyme was also recognized together with infiltration of leukemic cells in the interstitium. The diagnosis of kidney infiltration by chronic myelomonocytic leukemia (CMML) and lysozyme-induced tubular injury was eventually made. Our case is the first report showing extracapillary infiltration of leukemic cells by immunostaining. In addition, lysozyme-induced tubular injury is a forgotten cause of kidney injury in patients with CMML. This case teaches us the rare and forgotten causes of AKI with CMML.

No new community COVID-19 infection in four consecutive weeks: what lesson can be learned from Vietnam.

Sharing a common land border with China, Vietnam has faced a high risk of transmission of Coronavirus Disease 2019 (COVID-19). Rapid decision making and robust public health measures were established by the Vietnamese Government to control the situation. As of 17 May 2020, Vietnam reported 320 total confirmed cases of COVID-19, of whom 260 had fully recovered, while the remaining 60 cases were still under treatment. Noteworthy, the current data still confirms zero deaths and within the last 32 consecutive days prior to this submission, there have been no new infections in the country. Valuable lessons from Severe Acute Respiratory Syndrome in 2003 such as use of quarantine, early recognition and quick response to the infection, and increased awareness of its citizens have put Vietnam in a somewhat better position against COVID-19 compared to other places. Vietnam, at the current time, mulls declaring an end of the current COVID-19 outbreak.

Pilsicainide Intoxication with Neuropsychiatric Symptoms Treated with Continuous Hemodiafiltration.

A 72-year-old lady with atrial fibrillation and chronic renal failure was hospitalized due to bradycardic shock with electrocardiographic QRS prolongation. She had experienced limb shaking two days before hospitalization, and additionally developed hallucinations one day before admission. Pilsicainide intoxication was diagnosed from a review of her medications and electrocardiographic findings. Consequently, continuous hemodiafiltration was performed resulting in a resolution of the hallucinations and the QRS prolongation. This is a rare case of psychiatric symptoms caused by pilsicainide intoxication. It is important to know the mode of excretion of a drug and to adjust its dose, so that such drug-related incidents can be avoided.

Guillain-Barré Syndrome: A Variant Consisting of Facial Diplegia and Paresthesia with Left Facial Hemiplegia Associated with Antibodies to Galactocerebroside and Phosphatidic Acid.

BACKGROUND A rare variant of Guillain-Barré syndrome (GBS) consists of facial diplegia and paresthesia, but an even more rare association is with facial hemiplegia, similar to Bell's palsy. This case report is of this rare variant of GBS that was associated with IgG antibodies to galactocerebroside and phosphatidic acid. CASE REPORT A 54-year-old man presented with lower left facial palsy and paresthesia of his extremities, following an upper respiratory tract infection. Physical examination confirmed lower left facial palsy and paresthesia of his extremities with hyporeflexia of his lower limbs and sensory loss of all four extremities. The differential diagnosis was between a variant of GBS and Bell's palsy. Following initial treatment with glucocorticoids followed by intravenous immunoglobulin (IVIG), his sensory abnormalities resolved. Serum IgG antibodies to galactocerebroside and phosphatidic acid were positive in this patient, but not other antibodies to glycolipids or phospholipids were found. Five months following discharge from hospital, his left facial palsy had improved. CONCLUSIONS A case of a rare variant of GBS is presented with facial diplegia and paresthesia and with unilateral facial palsy. This rare variant of GBS may which may mimic Bell's palsy. In this case, IgG antibodies to galactocerebroside and phosphatidic acid were detected.

Platypnea-orthodeoxia Syndrome Induced by an Infected Giant Hepatic Cyst.

An 83-year-old man was admitted with a chief complaint of exacerbation of dyspnea. His blood oxygen saturation was 90% in the recumbent position despite oxygen therapy, and it dropped to less than 80% when the patient attempted to sit upright. A computed tomography scan revealed a giant hepatic cyst compressing the right atrium and the inferior vena cava. After percutaneous drainage, the oxygen saturation improved and did not change with alteration of the patient's positions from recumbent to sitting or standing. This case report describes a patient with the platypnea-orthodeoxia syndrome due to a giant hepatic cyst successfully managed by percutaneous drainage.

A Simple Algorithm for Predicting Bacteremia Using Food Consumption and Shaking Chills: A Prospective Observational Study.

BACKGROUND: Predicting the presence of true bacteremia based on clinical examination is unreliable. OBJECTIVE: We aimed to construct a simple algorithm for predicting true bacteremia by using food consumption and shaking chills. DESIGN: A prospective multicenter observational study. SETTING: Three hospital centers in a large Japanese city. PARTICIPANTS: In total, 1,943 hospitalized patients aged 14 to 96 years who underwent blood culture acquisitions between April 2013 and August 2014 were enrolled. Patients with anorexia-inducing conditions were excluded. INTERVENTIONS: We assessed the patients' oral food intake based on the meal immediately prior to the blood culture with definition as "normal food consumption" when >80% of a meal was consumed and "poor food consumption" when <80% was consumed. We also concurrently evaluated for a history of shaking chills. MEASUREMENTS: We calculated the statistical characteristics of food consumption and shaking chills for the presence of true bacteremia, and subsequently built the algorithm by using recursive partitioning analysis. RESULTS: Among 1,943 patients, 223 cases were true bacteremia. Among patients with normal food consumption, without shaking chills, the incidence of true bacteremia was 2.4% (13/552). Among patients with poor food consumption and shaking chills, the incidence of true bacteremia was 47.7% (51/107). The presence of poor food consumption had a sensitivity of 93.7% (95% confidence interval [CI], 89.4%-97.9%) for true bacteremia, and the absence of poor food consumption (ie, normal food consumption) had a negative likelihood ratio (LR) of 0.18 (95% CI, 0.17-0.19) for excluding true bacteremia, respectively. Conversely, the presence of the shaking chills had a specificity of 95.1% (95% CI, 90.7%-99.4%) and a positive LR of 4.78 (95% CI, 4.56-5.00) for true bacteremia. CONCLUSION: A 2-item screening checklist for food consumption and shaking chills had excellent statistical properties as a brief screening instrument for predicting true bacteremia.

Pasteurella multocida Infective Endocarditis: A Possible Link with Primary Upper Respiratory Tract Infection.

A 50-year-old Japanese man presented with fever and upper respiratory tract symptoms that required urgent inpatient admission. A physical examination revealed conjunctival hemorrhages and peripheral embolic phenomena. Blood cultures grew Pasteurella multocida, and an echocardiography revealed a mitral valve vegetation suggestive of infective endocarditis (IE), which was confirmed using the Modified Duke Criteria. After several antibiotic regimens proved ineffective, valve replacement was performed, with a good eventual outcome. P. multocida IE is rare and may sometimes have no preceding risk factors. P. multocida infections of the upper respiratory tract are unusual but may be an inciting event for IE. It is essential to check blood cultures and to repeat the performance of physical examinations to appreciate the developing features of IE.

Effectiveness of early ureteric stenting for urosepsis associated with urinary tract calculi.

OBJECTIVE: Patients with urosepsis associated with urinary tract calculi occasionally require drainage, primarily via ureteric stenting. Such patients require longer hospitalization. However, the indications for early ureteric stenting for this condition have not been clearly defined. To compare the length of stay (LOS) in the hospital between patients treated with earlier ureteric stenting versus those with delayed ureteric stenting. METHODS: Design: Retrospective cohort study. Setting: An acute care teaching hospital in Japan. MEASUREMENT: Length of hospital stay in days. Patients Patients with urosepsis associated with urinary tract calculi. RESULTS: Among a total of 30 patients (mean age, 72; 13 men), the mean number of days from emergency room admission to ureteric stenting was 3.5 days (range, 1-14 days), and the overall mean LOS was 36 days (range, 8-102 days). The early stenting group (mean LOS, 21 days) had a significantly shorter LOS than the delayed stenting group (mean LOS, 50 days), with an adjusted beta coefficient of -26 days [95% confidence interval (CI), -46, -6]. CONCLUSION: In patients with urosepsis associated with urinary tract calculi, performing early stenting within two days of admission may reduce the LOS in the hospital.

Gonococcal endocarditis in a 47-year-old Japanese man.

A 47-year-old sexually active Japanese man was admitted with a persistent fever and weight loss. A physical examination revealed a cardiac murmur. A transthoracic echocardiogram was nondiagnostic, although blood cultures grew Neisseria gonorrhoeae. Gonococcal endocarditis was diagnosed based on the modified Duke criteria. The administration of antimicrobial therapy resulted in an adequate initial resolution; however, two months after completing the therapy, the patient developed cardiac failure. Severe aortic regurgitation was identified, and the patient underwent emergent aortic valve replacement. Despite the rarity of gonococcal endocarditis, this disease should nevertheless be considered in patients presenting with a fever, cardiac murmur and a consistent sexual history.

Emergency airway management in geriatric and younger patients: analysis of a multicenter prospective observational study.

OBJECTIVES: There is little information on geriatric emergency airway management. We sought to describe intubation practices and outcomes for emergency department (ED) geriatric and younger patients in Japan. METHOD: We formed the Japanese Emergency Airway Network, a consortium of 11 medical centers, and prospectively collected data on ED intubations between 2010 and 2011. All patients 18 years or older who underwent emergent airway management were included in our study. Patients were divided to into 2 groups: 18 to 64-year olds and 65 years or older. We present descriptive data as proportions with 95% confidence intervals (CI). RESULTS: The database recorded 3277 patients (capture rate 96%), and 3178 met the inclusion criteria. Of 3178 patients, 1844 (58%) were 65 years or older, 1334 (42%) were 18 to 64 years old, 809 (25%) were 80 years or older, and 407 (50%) of them were in the state of cardiac arrest. The geriatric group, compared to the younger group, had a higher success rate on the initial attempt (71% vs 64%; difference 7%; 95% CI 4%-10%;) and in 2 attempts (90% vs 88%; difference 3%; 95% CI 1%-5%) or less. There was no significant difference in the adverse event rates by age group (difference 0%; 95% CI -2% to 3%). CONCLUSION: In our multicenter study involving a large geriatric population, we found that geriatric patients were intubated with a higher success rate, compared to younger patients. These data provide implications for the geriatric ED airway practice that may lead to better patient-centered emergency care.

Predicting bacteremia based on nurse-assessed food consumption at the time of blood culture.

BACKGROUND: Bacteremia and its complications are important causes of morbidity and mortality in hospitalized patients. However, the yield of blood cultures is relatively low, with many false-positive results from bacterial contamination. METHODS: We investigated the relationship between patient food consumption and the presence of bacteremia. This was an observational analysis of a cohort of 1179 patients who underwent blood culture analysis between January 2005 and December 2009. Patients with anorexia-inducing conditions, such as gastrointestinal illness and malignant disease treated with chemotherapy, were excluded. Food consumption was rated by nurses as the percentage of food consumed during the meal preceding the blood culture. Groupings were as follows: low consumption (<50%), moderate (>50% to <80%), and high (>80%). RESULTS: Low consumption was observed in 39.8% of patients, moderate in 17.8%, and high in 41.6%. The average body temperature was 38.1 ± 1.1°C. Bacteremia was present in 18.5%, 3.9%, and 1.4% of patients in the low, moderate, and high food consumption groups, respectively. The negative predictive value was 98.3%, suggesting that bacteremia is very unlikely in the setting of good food intake. CONCLUSION: Bacteremia is an unlikely occurrence in hospitalized patients who maintain adequate food consumption at the time of blood culture.

A rare case of group A streptococcal endocarditis with absence of valvular vegetation.

Group A streptococcal endocarditis has been described in intravenous drug misusers and as a post-varicella infection in children. We report a 64-year-old man with no prior risk factors who presented with a persistent fever, malaise, polyuria and cola-colored urine. On examination peripheral stigmata of endocarditis without a cardiac murmur and asymptomatic pharyngeal exudates were found. Blood and urine analysis revealed renal failure from suspected glomerulonephritis. Blood cultures revealed fully sensitive Group A streptococci. Transthoracic and transesophageal echocardiographies revealed no vegetation. The Modified Duke's Criteria aided in the diagnosis of definite infective endocarditis, despite the absence of valvular vegetation.
