Thyroid storm-related heart failure is a rare, life threatening complication of hyperthyroidism. In refractory cases, urgent thyroidectomy is required for definitive control of thyrotoxicosis. venoarterial extracorporeal membrane oxygenation (VA-ECMO) is a supportive measure for cardiorespiratory failure requiring continuous anticoagulation to prevent clotting. We presented two cases of thyrotoxic cardiac failure that necessitated VA-ECMO. One of the patients was successfully treated with thyroidectomy while on VA-ECMO. To the best of our knowledge, only two such cases have previously been reported.

Background: Sodium-glucose cotransporter 2 inhibitors (SGLT2i) (such as canagliflozin, empagliflozin, and dapagliflozin) are widely used to treat patients with type 2 diabetes mellitus (T2DM) to improve glycemic, cardiovascular and renal outcomes. However, based on post-marketing data, a warning label was added regarding possible occurrence of acute kidney injury (AKI).

Objectives: To describe the clinical presentation of T2DM patients treated with SGLT2i who were evaluated for AKI at our institution and to discuss the potential pathophysiologic mechanisms.

Methods: A retrospective study of a computerized database was conducted of patients with T2DM who were hospitalized or evaluated for AKI while receiving SGLT2i, including descriptions of clinical and laboratory characteristics, at our institution.

Results: We identified seven patients in whom AKI occurred 7–365 days after initiation of SGLT2i. In all cases, renin-angiotensin-aldosterone system blockers had also been prescribed. In five patients, another concomitant nephrotoxic agent (injection of contrast-product, use of nonsteroidal anti-inflammatory drugs or cox-2 inhibitors) or occurrence of an acute medical event potentially associated with AKI (diarrhea, sepsis) was identified. In two patients, only the initiation of SGLT2i was evident. The mechanisms by which AKI occurs under SGLT2i are discussed with regard to the associated potential triggers: altered trans-glomerular filtration or, alternatively, kidney medullary hypoxia.

Conclusions: SGLT2i are usually safe and provide multiple benefits for patients with T2DM. However, during particular medical circumstances, and in association with usual co-medications, particularly if baseline glomerular filtration rate is decreased, patients treated with SGLT2i may be at risk of AKI, thus warranting caution when prescribed.

Background: Disseminated intravascular coagulation associated with malignant bone marrow involvement has been described as a rare complication of gastric carcinoma and most patients die within 1–4 weeks. Effective chemotherapy of the underlying malignancy may be the only way to control acute DIC[1].

Objectives: To assess the benefit of infusional 5-fluorouracil as the primary treatment of metastatic gastric carcinoma and DIC at diagnosis.

Methods: From February 2001 to January 2005, six women (median age 48 years) with gastric carcinoma who presented with diffuse bone metastases and acute DIC were treated in our department. Diagnosis was based on primary gastric and bone marrow biopsies. DIC was confirmed by laboratory findings. Initial treatment consisted of infusional 5FU[2] 200 mg/m2/day. When the bleeding tendency stopped, cisplatin 60 mg/m2 and epirubicin 50 mg/m2 given every 3 weeks were added.

Results: Within one week of starting the treatment, the clinical and laboratory signs of acute DIC were resolved in five of six patients. Upon clinical improvement, five patients subsequently received epirubicin and cisplatin. Survival, however, was short (mean 15 weeks). All patients died with symptoms of bleeding, showing clinical and laboratory signs of DIC.

Conclusions: Based on our experience, infusional 5FU is an effective regimen with negligible myelosuppression; thus, it may be a good choice as initial therapy for this group of patients. The response induced by protracted 5FU was usually short and lasted for a few weeks only. Therefore, once DIC symptoms are controlled, the addition of newer cytotoxic drugs may be necessary to consolidate the remission.
