Observations from a Prospective Follow-up associated with Thyroid Perform and Autoimmunity amid COVID-19 Children.
Pancreaticoduodenectomy (PD) has been increasingly performed as a safe treatment option for periampullary malignant and benign disorders. However, the operation may result in significant postoperative complications. Here, we present a case that recurrent pyogenic liver abscess after PD is caused by common hepatic artery injury in atypical celiac axis anatomy.

A 56-year-old man with a 1-d history of fever and shivering was diagnosed with hepatic abscess. One year and five months ago, he underwent PD at a local hospital to treat chronic pancreatitis. After the operation, the patient had recurrent intrahepatic abscesses for 4 times, and the symptoms were relieved after percutaneous transhepatic cholangial drainage combining with anti-inflammatory therapy in the local hospital. Further examination showed that the recurrent liver abscess after PD was caused by common hepatic artery injury due to abnormal abdominal vascular anatomy. The patient underwent percutaneous drainage but continued to have recurrent episodes. His condition was eventually cured by right hepatectomy. In this case, preoperative examination of the patient's anatomical variations with computed tomography would have played a pivotal role in avoiding arterial injuries.

A careful computed tomography analysis should be considered mandatory not only to define the operability (with radical intent) of PD candidates but also to identify atypical arterial patterns and plan the optimal surgical strategy.

Esophagogastric varices are a common complication of cirrhosis with portal hypertension and endoscopic treatment has been recognized as a primary preventive and therapeutic option for such patients; however, it should be noted that bradyarrhythmia is regarded as one of the contraindications to endoscopic examination. Meanwhile, acute variceal bleeding may result in a high mortality rate in cirrhotic patients with portal hypertension accompanied by bradyarrhythmia. At present, there is an absence of reports concerning the treatment of such group of patients who underwent transjugular intrahepatic portosystemic shunt (TIPS). The present report details the case of a cirrhotic patient with acute variceal bleeding accompanied by bradyarrhythmia who underwent TIPS under temporary pacemaker protection.

We report the case of a 64-year-old male patient who was confirmed with bradyarrhythmia by ambulatory electrocardiogram 24 h before the operation. The patient was successfully treated by TIPS under temporary pacemaker protection.

In terms of cirrhotic patients with abnormal cardiac electrophysiological conduction, TIPS may be effective in reducing the complications of portal hypertension following the exclusion of severe pulmonary hypertension and heart failure, showing moderate feasibility in clinical applications.

Colorectal mucinous adenocarcinoma is a rare subtype of colorectal cancer and is characterized by an abundance of mucin in the tumor. In addition, the colorectal mucinous adenocarcinoma often demonstrates poor differentiation in the histology of tumor cells and poor prognosis compared with those with adenocarcinoma. Here, we present the case of a young woman with colonic mucinous adenocarcinoma showing significantly rapid progression within four months of immunosuppressant therapy for Henoch-Schönlein purpura.

Here we report a rare case of ascending colon mucinous adenocarcinoma with lymph node and liver metastases which developed and progressed rapidly within four months during the treatment of Henoch-Schönlein purpura using corticosteroids. The systemic screening examinations showed no tumors before the immunosuppressant therapy. Fortunately, the patient was successfully treated with chemotherapy.

While no direct evidence that the immunosuppressants accelerated the tumor development, the case presenta tion and review of the literature demonstrated that surveillance for malignancies before and during treatment with immunosuppressive agents is essential.

Choriocarcinoma is a subtype of gestational trophoblastic disease, gestational trophoblastic neoplasia. Orforglipron agonist Patients with brain metastasis are rare and information on the optimal treatment and patient outcome is limited. In order to improve the prognosis of this disease, accurate and timely treatments are very important for the patient of brain metastasis by choriocarcinoma.

A 17-year-old unmarried girl was misdiagnosed with a cerebral hemangioma with intracranial hemorrhage in a local hospital after presentation with severe head pain. She underwent craniotomy three times for treatment. The pathological results of posterior intracranial hematoma showed choriocarcinoma, and the patient was diagnosed as choriocarcinoma (21 points in stage IV). After uterine artery embolization, etoposide, methotrexate, actinomycin D, cyclophosphamide, and vincristine chemotherapy for 7 cycles, and whole brain radiotherapy, the patient achieved remission. She has been followed for 2 years with no signs of tumor recurrence.

Visceral disseminated varicella-zoster virus (VZV) infection is a rare but life-threatening disease. In transplant recipients with VZV infection, visceral dissemination may develop without skin eruptions, which leads to the failure of early diagnosis.

The patient was a 33-year-old male renal recipient who was referred to our hospital with severe upper abdominal pain of 3-d duration. On admission, the patient rapidly developed septic shock and multiple organ dysfunction syndrome with liver dysfunction and acute kidney injury. Next-generation sequencing of peripheral blood yielded 39224 sequence reads of VZV, and real-time polymerase chain reaction for VZV was positive, with 1.2 × 10
copies/mL. The final diagnosis was visceral disseminated VZV infection. Acyclovir and supportive therapy were started, but the patient died of severe visceral organ damage 16 h after admission.

Visceral disseminated VZV infection is possible in renal transplant recipients presenting abdominal pain and rapidly-evolving organ damage without skin involvement.

Hemophagocytic lymphohistiocytosis (HLH) is a rare and life-threatening disease caused by inherited pathogenic mutations and acquired dysregulations of the immune system. Composite lymphoma is defined as two or more morphologically and immunophenotypically distinct lymphomas that occur in a single patient. Here, we report two cases of HLH secondary to composite lymphoma with mixed lineage features of T- and B-cell marker expression both in the bone marrow and lymph nodes in adult patients.

Two patients were diagnosed with HLH based on the occurrence of fever, pancytopenia, lymphadenopathy, splenomegaly, hemophagocytosis and hyperferritinemia. Immunohistochemical staining of the axillary lymph node and bone marrow in case 1 showed typical features of combined B-cell and T-cell lymphoma. In addition, a lymph node gene study revealed rearrangement of the T-cell receptor chain and the immunoglobulin gene. Morphology and immunohistochemistry studies of a lymph node biopsy in case 2 showed typical features of T cell lymphoma, but immunophenotyping by flow cytometry analysis of bone marrow aspirate showed B cell lymphoma involvement. The patients were treated with high-dose methylprednisolone combined with etoposide to control aggressive HLH progression. The patients also received immunochemotherapy with the R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) regimen immediately after diagnosis. Both patients presented with highly aggressive lymphoma, and died of severe infection or uncontrolled HLH.

We present two rare cases with overwhelming hemophagocytosis along with composite T- and B-cell lymphoma, which posed a diagnostic dilemma. HLH caused by composite lymphoma was characterized by poor clinical outcomes.

Hepatocellular carcinoma is an aggressive tumor, and its latency and lack of clinical symptoms mean that most patients are already in the late stage when diagnosed. Large tumor volume and metastasis are the main reasons for not attempting surgery. Portal vein embolization and associated liver partition and portal vein ligation for staged hepatectomy are commonly used in clinical practice to increase the volume of remnant liver to allow surgical resection; however, research in this area is currently lacking.

A 48-year-old male patient with a history of viral hepatitis B for at least 30 years attended our center with a hepatic space-occupying lesion detected 3 d previously. Enhanced computed tomography scanning of the upper abdomen revealed a large mass in the right lobe of the liver, centered on the right posterior lobe, with the larger section measuring about 14 cm × 10 cm × 14 cm. He successfully underwent conversion therapy for a large right liver tumor after combined hepatic artery ligation and transcatheter arterial chemoembolization, and finally had an opportunity to undergo right hemi-hepatectomy and cholecystectomy. He remained asymptomatic with no obvious abnormalities on computed tomography scanning review at 2 mo after surgery.

This case highlights new ideas and provides a reference for conversion therapy of large liver tumors.

The concurrence of acute myeloid leukemia (AML) and chronic lymphocytic leukemia (CLL) is rare. Previous reports of such cases have focused mainly on clinical diagnosis and characteristics, so the mechanism remains unclear, and therapy options have been poorly explored.

Here, we report two cases of synchronous AML and CLL. Flow cytometry revealed two distinct abnormal cell populations (myeloblasts and lymphoid cells) according to scatter characteristics. CD5-positive B cell lymphoma with myeloid leukemia invasion was observed on lymph node biopsy. Chemotherapy regimens indicated for both AML and CLL were used in our patients, and our patients achieved complete response after chemotherapy. Next-generation sequencing of 88 genes was performed.

We conclude that early mutation and dysregulation at the hematopoietic stem cell stage and the accumulation of multiple rearrangements may cause the concurrence of CLL and AML. The treatment of infection and combination therapy aimed at the CLL component are significant in the management of patients with concurrent CLL and AML.
