It is characterized by hyponatremia and decreased serum osmolarity as well as an increase in urinary osmolarity. The most common etiological factors of this syndrome include diseases or trauma of the central nervous system and malignant tumor or inflammation of the lung. SIADH following abdominal surgery is rare. METHODS: We report the case of a 68-year-old woman who developed, 24 hours after common bile duct exploration and stone removal, continuous hyponatremia for 20 days and clinical manifestations of nausea, vomiting, and lethargy without focal neurological signs. RESULT: Laboratory examinations supported the diagnosis of SIADH. After therapy with fluid restriction, the patient recovered. CONCLUSION: There are diverse causes for SIADH. It is important to have kept this clinical possibility in mind in the differential diagnosis of refractory hyponatremia under any circumstances.展开更多

Although typical presentations include fever and pneumonia, we describe a case of COVID-19 presenting with neurological symptoms of encephalitis and infectious-related syndrome of inappropriate anti-diuretic hormone secretion. Because of the epidemic health problems, it is crucial to identify these patients as early as possible to follow the isolation procedures. We suggest that unclear neurological clinical presentations of patients should be considered for COVID-19.展开更多

The aim of the current study was to investigate the inappropriate use of antibiotics in adults with acute infectious diarrhea and to evaluate the association between the use of antibiotics and clinical features. To achieve this aim, we reviewed 4891 patients' medical records from Apr. 2008 to Oct. 2009. Of the total 4891 cases, 30.5% had clinical features of invasive bacterial diarrhea, 48.1% were prescribed with antibiotics, and 20.3% received inappropriate antibiotic treatment. Of note, 19% involved unnecessary antibiotic prescriptions in non-indicated cases, which accounted for 39.4% of all antibiotics prescribed in the total 4891 patients. There was no significant differences between physicians and medical trainees in the inappropriate use of antibiotics (P = 1.0). Logistic regression analysis demonstrated that except for body temperature, other clinical symptoms including abdominal pain, tenesmus, and faecal WBC count (〉10 cells/HPF) were associated with the use of antibiotics. In addition, other clinical indicators including vomiting, stool frequency of 5-10 times/d, mucous stool, and fecal WBC count of 1-10 cells/HPF, which are not normally indicators for prescribing antibiotics, were also associated with the use of antibiotics. This might suggest that these symptoms were mistaken as features of invasive bacterial diarrhea, thus leading to the overuse of antibiotics.展开更多

This study was to investigate the different prevalence of PIM use in elderly inpatients between 65-70 years of age and 80 years or older, who were discharged from Geriatric Depamnent in West China Hospital. Methods: A large-scale cohort of 1796 inpatients aged 65 years or over was recruited. Respectively. 618 patients were 65 79 years and 1178 patients were 80 years or older. Updated 2012 Beers Criteria by the Anaerican Geriatric Society was applied to assess the use of PIM among the investigated samples. Results: A review of the prescribed medications identified 686 patients aged 80 years or older constimed at least one PIM giving a rate of 58.2%. Conversely, 268 (43.4%) patients aged 65-79 years consumed at least one PIM (x^2=40.18, P 〈 0.001). Patients aged 80 years or older had higher hospitalization expenses, length of stay, co-morbidities, medical prescription, and mortality than patients aged 65-79 years (all with P 〈 0.001 ). Patients aged 80 years or older were prescribed with more benzodiazepines, drugs with strong anticholmergic properties, megestrol, antipsychotics, theophylline, and aspirin. In multiple regression analysis, PIM use was significantly associated with female gender, age, number of diagnostic disease, and number of prescribed medication. Conclusions: The finding from this study revealed that inpatients aged 80 years or older encountered more PIM use than those aged 65-79 years. Anticholinergic properties, megestrol. antipsychotics, theophylline, and aspirin are medications that often prescribed to inpatients aged 80 years or older. Doctors should carefully choose drugs for the elderly, especially the elderly aged 80 years or older.展开更多

Methods: A retrospective analysis was conducted on 12 patients suffered from SIADH after brain injury. The clinical features of these patients were similar to those of common hyponatremia. Most of the hyponatremia were detected by routine examinations. Supplement of salt as the initial treatment was used in these patients. If natremia did not rise or descended 2 3 days after treatment, SIADH was considered or diagnosed. Treatment scheme should be adjusted to limit water and natrium instead of supplying salt. Frusemide and albumin were the first choice for dehydration therapy. Results: 24 48 hours after limiting water and natrium, 12 patients natremia level was back to normal. Eight out of 12 patients were corrected completely in 1 week, 1 in 14 days, and 1 in 3 months after injury. Conclusions: Diagnosis of SIADH is difficult before treatment though effective treatment can be obtained if we adopt correct strategy. In these patients, the diagnosis of SIADH is confirmed in the course of treatment.展开更多

Inappropriate detection and therapy by ICDs are the most common causes of side effects that affect the quality of life in ICD recipients. This study evaluated the incidence and causes of inappropriate detection and therapy by ICDs in patients in our hospital. Methods From January 2000 to December 2005, fifty patients who received ICD implantation for ventricular arrhythmias for prevention of sudden cardiac death were evaluated in this study. Each ICD was programmed using clinical arrhythmic and cardiac data of the patient before discharge. Patients were followed up by standard schedule after implantation and all data retrieved from each device were collected and saved for further analysis. Results No arrhythmic event was detected in 12/50 (24%) patients during the period of follow-up. Among the remaining patients, 11 (22%) experienced inappropriate detections and therapies during follow-up in this study. ICD detected 383 ventricular tachyarrhythmia (VT) and 108 ventricular fibrillation (VF) episodes and delivered 678 therapies. In VT group, ICD delivered 413 antitachycardiac pacings (ATPs) and 118 shocks, among which 78 ATPs and 9 shocks were initiated by 55/383 (14.3%) inappropriate detections. In VF group ICD delivered 147 shocks, among which 56 shocks were initiated by 28/108 (26.9%) inappropriate detections. Overall, more than 50% of these episodes were caused by atrial fibrillation (AF) with rapid ventricular response, followed by electromagnetic or myopotential interference. In addition, most inappropriate therapies occurred within one year after ICD implantation. Conclusions About one fifth of patients experienced ICD inappropriate detection and therapy after implantation. The main cause was AF with rapid ventricular response, followed by electromagnetic or myopotential interference.展开更多

It is defined as hyponatremia in euvolemic patients, often due to abnormal secretion of antidiuretic hormone by tumor cells. Tolvaptan, a vasopressin-2-receptor antagonist, is currently recommended for patients affected by SIAD with mild or moderate symptoms. Among patients with prostatic cancer, SIAD represents a rare condition but it is frequently associated with poorly differentiated adenocarcinoma or pure small-cell carcinoma histotype. We report a case of SIAD appeared at disease progression in a 60-year-old male patient with acinar adenocarcinoma with neuroendocrine differentiation together with a literature review.展开更多

The hormone is stored in and released by the pituitary gland. When ADH (also called vasopressin) is produced somewhere other than the hypothalamus, the condition is called syndrome of inappropriate antidiuretic hormone (SIADH). A variety of conditions can trigger abnormal ADH production, but the main cause is cancer. It is frequently one of the first signs of lung cancer, especially small cell carcinoma, which produces ADH ectopically.l展开更多

文摘Colonoscopic screening has been reported to reduce deaths from colorectal cancer.Adequate bowel preparation is essential for this and safety is an important issue in choosing the methods.Polyethylene glycol(PEG)is regarded as a safe method for cleansing,especially compared with oral sodium phosphate.Here,we present a case of hyponatremia caused by the syndrome of inappropriate antidiuretic hormone(ADH)syndrome after PEG precolonoscopic cleansing resulting in generalized tonic-clonic seizures.A 62-year-old women had ingested PEG for precolonoscopic bowel cleansing.While waiting for the colonoscopy,she developed a stuporous mentality and generalized tonic-clonic seizures,which did not correlate with brain magnetic resonance imaging.Her serum sodium level was 113 mEq per liter and laboratory analyses were consistent with inappropriate ADH syndrome.Her thyroid and adrenal functions were normal.There were no malignancies,infections,respiratory disorders or central nervous disorders and she had no history of taking either diuretics or other medications,which might have caused inappropriate ADH syndrome.She was treated with 3%hypertonic saline and showed a complete neurological recovery as her sodium levels recovered.Follow-up visits showed the patient to have a normal sodium level without neurologic deficits.This case shows that inappropriate ADH syndrome can be caused by PEG preparation,which implies that physicians have to be aware of the possible side effects of this colonic cleansing approach and mindful of the possible ensuing symptoms.
文摘BACKGROUND Implantable cardioverter defibrillators(ICDs)and cardiac resynchronisation therapy with defibrillators(CRT-D)reduce mortality in certain cardiac patient populations.However,inappropriate shocks pose a problem,having both adverse physical and psychological effects on the patient.The advances in device technology now allow remote monitoring(RM)of devices to replace clinic follow up appointments.This allows real time data to be analysed and actioned and this may improve patient care.AIM To determine if RM in patients with an ICD is associated with fewer inappropriate shocks and reduced time to medical assessment.METHODS This was a single centre,retrospective observational study,involving 156 patients implanted with an ICD or CRT-D,followed up for 2 years post implant.Both appropriate and inappropriate shocks were recorded along with cause for inappropriate shocks and time to medical assessment.RESULTS RM was associated with fewer inappropriate shocks(13.6%clinic vs 3.9%RM;P=0.030)and a reduced time to medical assessment(15.1±6.8 vs 1.0±0.0 d;P<0.001).CONCLUSION RM in patients with an ICD is associated with improved patient outcomes.
文摘BACKGROUND Syndrome of inappropriate secretion of antidiuretic hormone(SIADH)is relatively common in several cancers,such as small cell lung cancer.However,nedaplatin-induced SIADH is rare.We describe a case of SIADH mediated by nedaplatin.CASE SUMMARY A 54-year-old female with nasopharyngeal carcinoma was treated with nedaplatin and developed severe hyponatremia due to SIADH.The side effects were successfully treated by fluid restriction and sodium supplementation.CONCLUSION This case report highlights the importance of cautiously treating life-threatening hyponatremia in patients treated with nedaplatin.
文摘We report a case of natural killer(NK)/T-cell lymphoma with concomitant syndrome of inappropriate antidiuretic hormone secretion(SIADH).The patient was a 64-yearold woman with a history of nasopharyngeal carcinoma of over 30 years.She was admitted with a chief complaint of intermittent fever for 2 mo.Palpation after admission indicated a swollen lymph node below the left jaw.Multiple imaging examinations on admission indicated multiple enlarged lymph nodes throughout the body.We performed a left submandibular lymph node biopsy,and the results revealed NK/T-cell lymphoma.A biochemical examination indicated Epstein-Barr virus positivity.At the same time,the patient developed hyponatremia.Based on her laboratory examination and clinical manifestation,decreased plasma osmolality,urine osmolality greater than plasma osmolality,lack of skin swelling,normal blood pressure,normal renal function,no adrenal function detected on serology,and no abnormalities in imaging examination of the adrenal glands,the likelihood of SIADH in the patient was high.After fluid restriction and administration of sodium chloride,the patient’s blood sodium level gradually increased.Subsequently,the immune function of the patient declined,there were severe symptoms of infection,and she died of respiratory failure.NK/T-cell lymphoma associated with SIADH has not,to our knowledge,been previously reported in PubMed.This case emphasizes the importance of monitoring serum ion levels,especially serum sodium,in patients with NK/T-cell lymphoma.

文摘BACKGROUND: The syndrome of inappropriate secretion of antidiuretic hormone (SIADH) as a dilutional hyponatremia is due to a pathological increase of antidiuretic hormone (ADH). It is characterized by hyponatremia and decreased serum osmolarity as well as an increase in urinary osmolarity. The most common etiological factors of this syndrome include diseases or trauma of the central nervous system and malignant tumor or inflammation of the lung. SIADH following abdominal surgery is rare. METHODS: We report the case of a 68-year-old woman who developed, 24 hours after common bile duct exploration and stone removal, continuous hyponatremia for 20 days and clinical manifestations of nausea, vomiting, and lethargy without focal neurological signs. RESULT: Laboratory examinations supported the diagnosis of SIADH. After therapy with fluid restriction, the patient recovered. CONCLUSION: There are diverse causes for SIADH. It is important to have kept this clinical possibility in mind in the differential diagnosis of refractory hyponatremia under any circumstances.

文摘Overuse of antibiotics for the treatment of acute diarrhea is very common. The aim of the current study was to investigate the inappropriate use of antibiotics in adults with acute infectious diarrhea and to evaluate the association between the use of antibiotics and clinical features. To achieve this aim, we reviewed 4891 patients' medical records from Apr. 2008 to Oct. 2009. Of the total 4891 cases, 30.5% had clinical features of invasive bacterial diarrhea, 48.1% were prescribed with antibiotics, and 20.3% received inappropriate antibiotic treatment. Of note, 19% involved unnecessary antibiotic prescriptions in non-indicated cases, which accounted for 39.4% of all antibiotics prescribed in the total 4891 patients. There was no significant differences between physicians and medical trainees in the inappropriate use of antibiotics (P = 1.0). Logistic regression analysis demonstrated that except for body temperature, other clinical symptoms including abdominal pain, tenesmus, and faecal WBC count (〉10 cells/HPF) were associated with the use of antibiotics. In addition, other clinical indicators including vomiting, stool frequency of 5-10 times/d, mucous stool, and fecal WBC count of 1-10 cells/HPF, which are not normally indicators for prescribing antibiotics, were also associated with the use of antibiotics. This might suggest that these symptoms were mistaken as features of invasive bacterial diarrhea, thus leading to the overuse of antibiotics.

文摘Background: Polyphamlacy and potentially inappropriate medications (PIMs) are prominent prescribing issties in elderly patients. This study was to investigate the different prevalence of PIM use in elderly inpatients between 65-70 years of age and 80 years or older, who were discharged from Geriatric Depamnent in West China Hospital. Methods: A large-scale cohort of 1796 inpatients aged 65 years or over was recruited. Respectively. 618 patients were 65 79 years and 1178 patients were 80 years or older. Updated 2012 Beers Criteria by the Anaerican Geriatric Society was applied to assess the use of PIM among the investigated samples. Results: A review of the prescribed medications identified 686 patients aged 80 years or older constimed at least one PIM giving a rate of 58.2%. Conversely, 268 (43.4%) patients aged 65-79 years consumed at least one PIM (x^2=40.18, P 〈 0.001). Patients aged 80 years or older had higher hospitalization expenses, length of stay, co-morbidities, medical prescription, and mortality than patients aged 65-79 years (all with P 〈 0.001 ). Patients aged 80 years or older were prescribed with more benzodiazepines, drugs with strong anticholmergic properties, megestrol, antipsychotics, theophylline, and aspirin. In multiple regression analysis, PIM use was significantly associated with female gender, age, number of diagnostic disease, and number of prescribed medication. Conclusions: The finding from this study revealed that inpatients aged 80 years or older encountered more PIM use than those aged 65-79 years. Anticholinergic properties, megestrol. antipsychotics, theophylline, and aspirin are medications that often prescribed to inpatients aged 80 years or older. Doctors should carefully choose drugs for the elderly, especially the elderly aged 80 years or older.
文摘Objective: To study the diagnosis and treatment of the syndrome of inappropriate antidiuretic hormone secretion (SIADH) after brain injury. Methods: A retrospective analysis was conducted on 12 patients suffered from SIADH after brain injury. The clinical features of these patients were similar to those of common hyponatremia. Most of the hyponatremia were detected by routine examinations. Supplement of salt as the initial treatment was used in these patients. If natremia did not rise or descended 2 3 days after treatment, SIADH was considered or diagnosed. Treatment scheme should be adjusted to limit water and natrium instead of supplying salt. Frusemide and albumin were the first choice for dehydration therapy. Results: 24 48 hours after limiting water and natrium, 12 patients natremia level was back to normal. Eight out of 12 patients were corrected completely in 1 week, 1 in 14 days, and 1 in 3 months after injury. Conclusions: Diagnosis of SIADH is difficult before treatment though effective treatment can be obtained if we adopt correct strategy. In these patients, the diagnosis of SIADH is confirmed in the course of treatment.
文摘Background Implantable cardioverter defibrillator (ICD) is the only effective therapy in patients with life threatening ventricular arrhythmias. Inappropriate detection and therapy by ICDs are the most common causes of side effects that affect the quality of life in ICD recipients. This study evaluated the incidence and causes of inappropriate detection and therapy by ICDs in patients in our hospital. Methods From January 2000 to December 2005, fifty patients who received ICD implantation for ventricular arrhythmias for prevention of sudden cardiac death were evaluated in this study. Each ICD was programmed using clinical arrhythmic and cardiac data of the patient before discharge. Patients were followed up by standard schedule after implantation and all data retrieved from each device were collected and saved for further analysis. Results No arrhythmic event was detected in 12/50 (24%) patients during the period of follow-up. Among the remaining patients, 11 (22%) experienced inappropriate detections and therapies during follow-up in this study. ICD detected 383 ventricular tachyarrhythmia (VT) and 108 ventricular fibrillation (VF) episodes and delivered 678 therapies. In VT group, ICD delivered 413 antitachycardiac pacings (ATPs) and 118 shocks, among which 78 ATPs and 9 shocks were initiated by 55/383 (14.3%) inappropriate detections. In VF group ICD delivered 147 shocks, among which 56 shocks were initiated by 28/108 (26.9%) inappropriate detections. Overall, more than 50% of these episodes were caused by atrial fibrillation (AF) with rapid ventricular response, followed by electromagnetic or myopotential interference. In addition, most inappropriate therapies occurred within one year after ICD implantation. Conclusions About one fifth of patients experienced ICD inappropriate detection and therapy after implantation. The main cause was AF with rapid ventricular response, followed by electromagnetic or myopotential interference.
文摘Syndrome of inappropriate antidiuresis (SIAD) is a common paraneoplastic syndrome commonly associated with thoracic malignancies, gastrointestinal cancers and kidney tumors. It is defined as hyponatremia in euvolemic patients, often due to abnormal secretion of antidiuretic hormone by tumor cells. Tolvaptan, a vasopressin-2-receptor antagonist, is currently recommended for patients affected by SIAD with mild or moderate symptoms. Among patients with prostatic cancer, SIAD represents a rare condition but it is frequently associated with poorly differentiated adenocarcinoma or pure small-cell carcinoma histotype. We report a case of SIAD appeared at disease progression in a 60-year-old male patient with acinar adenocarcinoma with neuroendocrine differentiation together with a literature review.
文摘The implantable cardioverter defibrillator (ICD) represents today the treatment and prophylaxis of choice for patients at risk for sustained ventricular tachyarrhythmias.1-6 Accurate sensing of ventricular tachyarrhythmias is a critical aspect of the function of ICD. All currently available models include algorithms with variable sensitivity, allowing adjustments which optimize the detection of low amplitude signals during ventricular tachyarrhythmia. However,
文摘Antidiuretic hormone (ADH) is produced by an area of he brain called the hypothalamus. The hormone is stored in and released by the pituitary gland. When ADH (also called vasopressin) is produced somewhere other than the hypothalamus, the condition is called syndrome of inappropriate antidiuretic hormone (SIADH). A variety of conditions can trigger abnormal ADH production, but the main cause is cancer. It is frequently one of the first signs of lung cancer, especially small cell carcinoma, which produces ADH ectopically.l
文摘Nappropriate diction in the English Descriptions is complex and difficult to solve.In my study,I introduces four types of inappropriateness classified on the basis of related linguistic theories that deal with the choice of words.The four types of inappropriate diction are entitled respectively semantic inappropriateness,pragmatic inappropriateness,stylistic inappropriateness and social inappropriateness.
