Polyneuropathy organomegaly endocrinopathy M-protein and skin changes syndrome with ascites as an early-stage manifestation:A case report

BACKGROUND Polyneuropathy organomegaly endocrinopathy M-protein and skin changes(POEMS)syndrome is a rare paraneoplastic syndrome caused by a potential plasma cell tumor.The clinical manifestations of POEMS syndrome are diverse.Due to the insidious onset and lack of specific early-stage manifestations,POEMS syndrome is easily misdiagnosed or never diagnosed,leading to delayed treatment.Neurological symptoms are usually the first clinical manifestation,while ascites is a rare symptom in patients with POEMS syndrome.CASE SUMMARY A female patient presented with unexplained ascites as an initial symptom,which is a rare early-stage manifestation of the condition.After 1 year,the patient gradually developed progressive renal impairment,anemia,polyserosal effusion,edema,swollen lymph nodes on the neck,armpits,and groin,and decreased muscle strength of the lower extremities.The patient was eventually diagnosed with POEMS syndrome after multidisciplinary team discussion.Treatment comprised bortezomib+dexamethasone,continuous renal replacement therapy,chest and abdominal closed drainage,transfusions of erythrocytes and platelets,and other symptomatic and supportive treatments.The patient’s condition initially improved after treatment.However,then her symptoms worsened,and she succumbed to the illness and died.CONCLUSION Ascites is a potential early manifestation of POEMS syndrome,and this diagnosis should be considered for patients with unexplained ascites.Furthermore,multidisciplinary team discussion is helpful in diagnosing POEMS syndrome.

Repeated pancreatitis-induced splenic vein thrombosis leads to intractable gastric variceal bleeding: A case report and review

Gastric varices(GV) are one of the most common complications for patients with portal hypertension. Currently, histoacryl injection is recommended as the initial treatment for bleeding of GV, and this injection has been confirmed to be highly effective for most patients in many studies. However, this treatment might be ineffective for some types of GV, such as splenic vein thrombosis-related localized portal hypertension(also called left-sided, sinistral, or regional portal hypertension). Herein, we report a case of repeated pancreatitis-induced complete splenic vein thrombosis that led to intractable gastric variceal bleeding, which was treated by splenectomy. We present detailed radiological and pathological data and blood rheology analysis(the splenic artery- after a short gastric vein or stomach vein- gastric coronary vein- portal vein). The pathophysiology can be explained by the abnormal direction of blood flow in this patient. To our knowledge, this is the first reported case for which detailed patho-logy and blood rheology data are available.

Portal hypertension exacerbates intrahepatic portosystemic venous shunt and further induces refractory hepatic encephalopathy: A case report

BACKGROUND Intrahepatic portosystemic venous shunt(IPSVS)is a rare hepatic disease with different clinical manifestations.Most IPSVS patients with mild shunts are asymptomatic,while the patients with severe shunts present complications such as hepatic encephalopathy.For patients with portal hypertension accompanied by intrahepatic shunt,portal hypertension may lead to hemodynamic changes that may result in exacerbated portal shunt and increased shunt flow.CASE SUMMARY A 57-year-old man,with the medical history of chronic hepatitis B and liver cirrhosis,was admitted to our hospital with abnormal behavior for 10 mo.He had received the esophageal varices ligation and entecavir therapy 1 year ago.Comparing with former examination results,the degree of esophageal varices was significantly reduced,while the right branch of the portal vein was significantly expanded and tortuous.Meanwhile,abdominal ultrasound presented the right posterior branch of portal vein connected with the retrohepatic inferior vena cava.The imaging findings indicated the diagnosis of IPSVS and hepatic encephalopathy.Instead of radiologic interventions or surgical therapies,this patient had only accepted symptomatic treatment.No recurrence of hepatic encephalopathy was observed during 1-year follow-up.CONCLUSION Hemodynamic changes may exacerbate intrahepatic portosystemic shunt.The intervention or surgery should be carefully applied to patients with severe portal hypertension due to the risk of hemorrhage.

Control Model of Multifunctional Hot Metal Ladles

For further research on the control model of muhifunctional hot metal ladles between the ironmaking and steelmaking interface, the hot metal ladies of K steel plant were taken as the object to analyze the operation process. The factors of blast furnace supply and basic oxygen furnace demand were proposed. According to the principle of supply and demand balance, the control model of hot metal was researched under the following factor conditions： equal to, greater than, and less than 1, respectively. The distribution model of the blast furnace, sleelmaking works, and online buffering was proposed. When the supply and demand factor is equal to ） , the turnover number of hot metal ladles equals 16 and the turnover cycle of hot metal ladles equals 512 min. When the factor is greater than 1, the total number of hot metal ladles is equal to the normal turnover number plus the turnover number of the cast iron machine. When the factor is less than 1, the total number of hot metal ladles is equal tO the normal turnover number plus the accumulating number. Satisfactory effects were obtained by applying the control model in produc tion. The numbers of turnover ladles and accumulating ladles were reduced.
