AIM: Some recent studies have reported that early intervention by a medical emergency team (MET) for clinical deterioration before intensive care unit (ICU) admission was associated with a survival benefit in critically ill cancer patients. We hypothesized that early MET intervention for an obstetric crisis in the general wards would be related to favorable outcomes in critically ill obstetric patients. METHODS: Data of obstetric patients who were managed by a MET were collected retrospectively from 1 March 2008 to 30 April 2015...

Dengue is a mosquito transmitted flaviviral infection which can give rise to severe haemorrhage (dengue haemorrhagic fever/DHF) and with capillary leakage induces hypovolemic shock (dengue shock syndrome/DSS). Although dengue symptoms and complications have been known for many decades there has only been one documented case of osteonecrosis of the maxilla which was treated by excision of the necrotic bone. In this case of dengue infection, extensive maxillary osteonecrosis and minimal root resorption appeared to follow factitious injury with a toothpick but resolved with nonsurgical management...

Dizziness is a common chief complaint in emergency medicine. The differential diagnosis is broad and includes serious conditions, such as stroke, cardiac arrhythmia, hypovolemic states, and acute toxic and metabolic disturbances. Emergency physicians must distinguish the majority of patients who suffer from benign self-limiting conditions from those with serious illnesses that require acute treatment. Misdiagnoses are frequent and diagnostic test costs high. The traditional approach does not distinguish benign from dangerous causes and is not consistent with best current evidence...

: Hemorrhagic rupture is a very rare complication of a simple hepatic cyst. We report the first case of a totally extraperitoneal rupture of a recurrent cyst, occurred in a 73-year-old man who presented with acute right hypochondralgia. Computed tomography revealed the rupture of a large hemorrhagic cyst in the right liver lobe and the formation of a voluminous hematoma in the retroperitoneal space. Despite the absence of hemoperitoneum, the entity of the bleeding led us to perform an urgent and successful surgical intervention...

BACKGROUND: Young patients with diabetes present with reduced compensatory responses to hypovolemic stress. Less compliant veins could be a contributing factor, since roughly two-thirds of the blood volume resides in the venous system as a blood reservoir, adjusting proper venous inflow to the heart. The aim of this study was to measure venous compliance and lower limb blood pooling during hypovolemic stress, and to correlate them to indices of diabetes severity and glucose control. METHODS: Fifteen young women with type 1 diabetes (DW) and 18 healthy age-matched women (C) were subjected to lower body negative pressure (LBNP) (11-44 mmHg), creating hypovolemic stress...

Intact cerebral blood flow (CBF) is essential for cerebral metabolism and function, whereas hypoperfusion in relation to hypovolemia and hypocapnia can lead to severe cerebral damage. This study was designed to assess internal carotid artery blood flow (ICA-BF) during simulated hypovolemia and noninvasive positive pressure ventilation (PPV) in young healthy humans. Beat-by-beat blood velocity (ICA and aorta) were measured by Doppler ultrasound during normovolemia and simulated hypovolemia (lower body negative pressure), with or without PPV in 15 awake subjects...

Massive bleeding of Dieulafoy lesions were reported about 1-2% of all digestive tract bleedings. As it occurs mainly in the stomach, it is rare in colon and rectum [1, 2]. Over-The-Scope-Clip (OTSC) delivered to the cecum guidewire-assisted technique could save the life in critical condition with hypovolemic shock due to Dieulafoy bleeding [3].

Hyponatremia is a common electrolyte disorder that arises from disturbances in water metabolism. In cases of acute advanced hyponatremia, serious symptoms are predominant, while chronic mild hyponatremia causes minor symptoms such as slowness, depression or unsteadiness of gait. Any therapy of hyponatremia depends on the severity of its symptoms and on its specific etiology and diagnosis. Concerning the differential diagnosis of the type of hyponatremia, it is initially helpful to distinguish between euvolemic, hypervolemic and hypovolemic forms of hyponatremia...

Hemolytic-uremic syndrome (HUS) is a common cause of organic acute renal failure (ARF) in children. It is a progressive complication of acute gastroenteritis (AGE), especially caused by Escherichia coli in children. This study aimed to describe the clinical, therapeutic and evolutionary aspects of this affection in four children. We collected four cases of HUS. The average age was 10,5 months (5-15mois), exclusively boys. Clinical examination revealed a hemolytic anemia (pallor and jaundice), oligoanuria and edematous syndrome (2 cases), arterial hypertension (1 patient), AGE associated with severe dehydration and hypovolemic shock (2 patients), consciousness disorders...

Spontaneous iliac vein rupture resulting in a retroperitoneal hematoma is extremely rare and can present as a life-threatening emergency. There is often a delay in diagnosis with no established treatment recommendations. We report the case of a 39-year-old woman who presented with hypovolemic shock, a large left retroperitoneal hematoma, and left lower extremity phlegmasia in the setting of a previously asymptomatic May-Thurner syndrome. She was successfully treated with a combined open and endovascular approach...

The hypothalamic paraventricular nucleus (PVN) plays a role in cardiovascular regulation through vasopressin release and sympathetic system. The PVN contains angiotensin II (AngII) immunoreactive cells, fibers and AngII receptors. We have already shown that microinjection of AngII into PVN produced a pressor response concomitant with an increase in firing rate of some PVN neurons. This study was performed to find if PVN AngII plays a regulatory function during hypotension. Hypovolemic-hypotension was induced and the possible role of the PVN AngII in returning arterial pressure toward normal was assessed by monitoring cardiovascular response and single-unit activity of the PVN neurons...

Teratomas are rare tumours which originate from all 3 germs cell layers namely endoderm, mesoderm and ectoderm, with varying proportions of each component. The most common site of teratoma is in the sacro-coccygeal region. Teratomas are generally benign and have well appreciable clinical and histopathological features. Incidence of congenital teratoma is 1 in 4000. In head and neck region congenital teratomas usually associated with other anomalies like cystic hygroma and cleft palate with an incidence of 1 in 400...

INTRODUCTION: Limited transthoracic echocardiogram (LTTE) has been shown to be a useful tool in guiding resuscitation in adult trauma patients. Our hypothesis is that image-guided resuscitation in pediatric trauma patients with LTTE is feasible. METHODS: A retrospective chart review was performed on highest level pediatric trauma alerts (age 18 years or younger) at our level I trauma center during a 6-month period. Patients were divided into 2 groups as follows: those who had LTTE performed (LTTE group) and those who did not have LTTE performed (non-LTTE group)...

A 57-year-old female patient received elective liver transplant due to nonalcoholic steatohepatitis complicated by hepatocellular carcinoma. Her preoperative Model for End-Stage Liver Disease score was 11. The total transplant ischemic time was 10 hours and 35 minutes, and the warm ischemic time was 35 minutes. Even with aggressive fluid overload and use of high concentrations of vasoactive amines, the patient developed possible primary graft dysfunction with poor response to fluids and vasopressor support, suggesting vasoplegic syndrome...
