Observational Study
BACKGROUND
Extracorporeal membrane oxygenation (ECMO) is used for severe cardiopulmonary failure, with veno-arterial ECMO for cardiogenic shock and veno-venous ECMO for acute respiratory failure. ECMO's application has expanded to ICUs, emergency departments, and operating rooms. ECMO patients are at high risk for complications, including acute kidney injury (AKI), often requiring renal replacement therapy (RRT), posing significant management challenges.
METHODS
From August 2015 to June 2022, 120 patients were cured with veno-venous ECMO (n = 60) or veno-arterial ECMO (VA-ECMO, n = 60) combined with CRRT in our hospital. In the control group (n = 60), the input end (arterial end) of CRRT was connected to the ECMO oxygenator. The reinfusion end (venous end) of CRRT was connected to the oxygenator of ECMO for CRRT + ECMO treatment. In the experimental group (n = 60), the input end (arterial end) of CRRT was connected to the oxygenator of ECMO, and an additional pressure regulating device was installed on the connection of the 2 lines. The observation indexes including clinical therapeutic effect, clinical therapeutic effect, the incidence of complications, and the incidence of complications were compared.
RESULTS
There was a notable decrease in serum creatinine, and the differences in blood urea nitrogen, procalcitonin, and C-reactive protein after operation were statistically significant (P < .05). The filter use time in the study group was notably longer (P < .01). There exhibited no remarkable difference in the incidences of bleeding, thrombosis, numbness of hands and feet, metabolic alkalosis, disseminated intravascular coagulation, organ dysfunction syndrome, hyperbilirubinemia, and infection.
CONCLUSION
This study demonstrates that additional pressure regulation devices are installed at the line connection between the CRRT input end and the CRRT return end to ensure that the flow rate of ECMO does not affect the CRRT treatment. ECMO and CRRT provide a safe pressure range so that the ECMO line can be safely connected to the CRRT machine at physiological pressure, reducing the occurrence of complications related to CRRT machine interruption and improving the efficiency of CRRT without affecting the efficiency of ECMO, ensuring patient safety.

INTRODUCTION
Severe metabolic alkaloses are relatively rare but can carry a high mortality rate. Treatment involves supportive care and treatment of underlying causes.
CASE REPORT
A 55-year-old male dependent on a gastrojejunostomy tube presented to the emergency department for altered mental status. The patient had metabolic alkalosis, electrolyte abnormalities, and prolonged QT interval on electrocardiogram. Examination and history revealed that chronic drainage of gastric fluid via malfunctioning a gastrojejunostomy tube resulted in profound alkalosis. The patient recovered with supportive care, electrolyte repletion, and gastrojejunostomy tube replacement.
CONCLUSION
This case highlights the importance of gastrointestinal acid-base pathophysiology.

INTRODUCTION
Diabetic ketoacidosis (DKA) is a common diagnosis in the emergency department (ED). However, one must consider other causes for acid-base disturbances when the pattern is not consistent with typical presentation.
CASE REPORT
A 52-year-old female with a history of insulin-dependent diabetes mellitus type 2 presented to the ED with abdominal pain, nausea, and vomiting for three days. Her diagnostic workup revealed diabetic ketoacidosis but with concurrent metabolic alkalosis. Standard treatment for DKA was initiated, and there was improvement of her mentation and resolution of metabolic derangements.
CONCLUSION
Overlooking a diagnosis of DKA because of alkalosis on venous blood gas testing could lead to inappropriate treatment and, therefore, increased risk of morbidity and mortality in the affected patient.

INTRODUCTION AND IMPORTANCE
The most common cancer among females worldwide and in Saudi Arabia is breast cancer. Lobular breast carcinoma is the second most common subtype of breast cancer. There are different patterns of metastasis as ductal breast cancer spreads to the liver, lung, brain, and bone while the lobular subtype metastasizes to the gastrointestinal tract.
CASE PRESENTATION
A 69-year-old Indian pilgrim presented to the ER complaining of abdominal pain, vomiting, and abdominal distention admitted as a case of intestinal obstruction. CT scan demonstrated intestinal obstruction with transition zone at the terminal ileum. The patient underwent exploratory laparotomy where she was found to have a mass at the terminal ileum. Resection of around 8 cm of small bowel and primary anastomosis were done, histopathology revealed metastatic lobular breast carcinoma.
CLINICAL DISCUSSION
Patients with metastatic breast cancer to the gastrointestinal tract often present with nonspecific symptoms, while acute cases present with complications such as perforation. In a retrospective review of metastatic breast cancer, the majority metastasizes to the colon and rectum, while 19 % to the small bowel. Palliative surgery is considered the first-line treatment of complicated patients, while stable cases are referred to medical oncology.
CONCLUSION
Breast cancer is the second most common cancer leading to death and lobular subtype has more propensity to metastasize to the gastrointestinal tract compared to ductal breast cancer. Regarding patients presenting to the emergency bay, treating the emergency complaints is the standard management. For immigrant patients, we highly recommend creating a data system for sending histopathology reports to facilitate follow-up in their countries.
CASE PRESENTATION
A 69-year-old Indian pilgrim patient presented to the ER complaining of abdominal pain for 3 days associated with nausea and vomiting, not passing stool nor flatus was admitted as a case of intestinal obstruction. On examination patient was in pain with tachycardia, abdominal distended with generalized tenderness. Labs revealed metabolic alkalosis with hypokalemia. Abdomen X-ray showed signs of intestinal obstruction with multiple air-fluid levels and dilated small bowel loops. CT scan abdomen and pelvis with IV contrast reported (Figs. 1,2) distended ileum around 5 cm proximal to the transition zone at the terminal ileum with mild free fluid in the abdomen and pelvis. The patient underwent exploratory laparotomy where she was found to have a mass at the terminal ileum with the proximal loop dilated and distal loops collapsed, and further exploration showed enlarged mesenteric lymph nodes. Small bowel resection of around 8 cm and side to side anastomosis was done to relive the intestinal obstruction. Gross pathology showed a solid lesion protruding into the lumen measuring 1.5*1.5*1.5 cm, while the microscopic description consists of small cells with round ovoid nuclei which lack cohesion and appear individually dispersed through a fibrous connective tissue and arranged in single file linear cords that invade the stroma (Fig. 4) concluded as metastatic lobular carcinoma of the breast. Immunohistochemistry reported CK7 + ve, ER + ve, EMA + ve and CKAE1/AE3 + ve. The patient had an uneventful recovery, then she was discharged against medical advice and traveled to her country after two days before the histopathology result and she lost follow-up with us.

This case report delves into the rare occurrence of hyperventilation syndrome (HVS) with hypocalcemia in an 18-year-old female diagnosed with autism spectrum disorder (ASD). The rare occurrence highlights the importance of recognizing the potential association between HVS, hypocalcemia, and ASD, emphasizing the need for comprehensive evaluation and management strategies in individuals with ASD presenting with unusual symptoms. Despite ongoing psychotherapeutic treatment, the patient's clinical examination revealed ASD-related communication anomalies. Treatment with Escitalopram resolved panic attacks but left residual anxiety. During an emergency room visit for menstrual-related abdominal pain, a hyperventilation crisis ensued, leading to respiratory alkalosis and hypocalcemia. Swift intervention, including closed mask ventilation and electrolyte infusion, successfully alleviated symptoms. Follow-up assessments indicated normal thyroid function and vitamin D levels. The case highlights the necessity for clinicians to consider electrolyte imbalances in anxiety attacks among ASD patients, emphasizing the importance of timely management for patient safety. The intricate interplay between hyperventilation syndrome, anxiety, and hypocalcemia in ASD patients is explored, offering valuable insights for the nuanced understanding and comprehensive assessment of such cases.

Gitelman syndrome (GS) is an inherited somatic recessive disorder characterized by hypokalemic metabolic alkalosis, accompanied by hypocalciuria and hypermagnesuria. It usually presents in late childhood or young adults with muscle weakness, tetany, or convulsions. Limited information is available in the literature regarding the proper management of this syndrome during pregnancy, as well as its effects on both the mother and the child. We herein present the case of a 16-year-old primigravida who was admitted to the emergency department with chief complaints of abdominal pain, weakness, and vomiting for the past three days during the 12th week of gestation. Routine blood investigations revealed hypokalemia and hypomagnesemia, and electrocardiography (ECG) showed ST-segment depressions. Further evaluation was performed due to persistent hypokalemia, and metabolic alkalosis, hypocalciuria, and hyperaldosteronism were found. Hence, a clinical diagnosis of GS took place. The pregnancy progressed smoothly without complications; potassium levels remained consistently below normal, requiring supplementation three times during pregnancy. Pregnant women with GS should be reported due to the rarity of cases, aiming to establish a standardized approach for monitoring and management.

Down syndrome often coincides with hypothyroidism, a condition that may lead to pericardial effusion (PE), though cardiac tamponade remains an infrequent complication. Cardiac tamponade is an emergency that requires immediate diagnosis and treatment. Here, we present a case of a patient who presented to the emergency department (ED) with Down syndrome associated with hypothyroidism and underwent immediate pericardiocentesis and pericardial window placement. A 52-year-old male, with a history of Down's syndrome and hypothyroidism, presented to the ED complaining of shortness of breath and chest pain. He had previously been diagnosed with PE. On examination, he exhibited average heart rate, low blood pressure, decreased heart sounds, and jugular venous distention, with no murmur or frictional rub. Initial investigations revealed normal sinus rhythm on EKG but an enlarged cardiac silhouette on chest X-ray. Laboratory tests showed elevated C-reactive protein and sedimentation rate, suggestive of inflammation, while arterial blood gas showed compensated respiratory alkalosis. Thyroid-stimulating hormone (TSH) was elevated. Despite supplemental oxygen, the patient's condition worsened, prompting a bedside ultrasound revealing cardiac tamponade. A cardiology consultation recommended immediate transfer for treatment. At a different hospital, pericardiocentesis was performed, followed by the placement of a pericardial window to prevent recurrence. Follow-up imaging showed improvement in pleural effusion and resolution of cardiac tamponade. The patient's symptoms improved, and he was discharged with regular follow-up. Down's syndrome is a chromosomal disorder characterized by the trisomy of chromosome 21. It is associated with various cardiac complications. Such patients have an elevated risk of PE due to a variety of reasons, such as viral infections, hypothyroidism, or autoimmune diseases. Although PE has been found, the incidence of cardiac tamponade has rarely been reported. The pathogenesis of PE in hypothyroidism is due to the leakage of fluids from the capillaries and the build-up of fluid in the pericardial space. The treatment of PE is treating hypothyroidism with thyroxine. In rare cases like ours, when the patient develops cardiac tamponade, the patient often needs pericardiocentesis. Our patient had to undergo pericardial window placement, as well to prevent recurrent symptoms. In conclusion, this case report sheds light on the occurrence of cardiac tamponade in a patient with Down's syndrome and hypothyroidism, a relatively rare complication that necessitates prompt recognition and intervention. Through this report, we emphasize the importance of considering cardiac tamponade in the differential diagnosis of patients with Down's syndrome presenting with symptoms suggestive of cardiovascular compromise.
