Review
Acute heart failure (AHF) is a syndrome defined as the new onset (de novo heart failure (HF)) or worsening (acutely decompensated heart failure (ADHF)) of symptoms and signs of HF, mostly related to systemic congestion. In the presence of an underlying structural or functional cardiac dysfunction (whether chronic in ADHF or undiagnosed in de novo HF), one or more precipitating factors can induce AHF, although sometimes de novo HF can result directly from the onset of a new cardiac dysfunction, most frequently an acute coronary syndrome. Despite leading to similar clinical presentations, the underlying cardiac disease and precipitating factors may vary greatly and, therefore, the pathophysiology of AHF is highly heterogeneous. Left ventricular diastolic or systolic dysfunction results in increased preload and afterload, which in turn lead to pulmonary congestion. Fluid retention and redistribution result in systemic congestion, eventually causing organ dysfunction due to hypoperfusion. Current treatment of AHF is mostly symptomatic, centred on decongestive drugs, at best tailored according to the initial haemodynamic status with little regard to the underlying pathophysiological particularities. As a consequence, AHF is still associated with high mortality and hospital readmission rates. There is an unmet need for increased individualization of in-hospital management, including treatments targeting the causative factors, and continuation of treatment after hospital discharge to improve long-term outcomes.

Review
High carbohydrate intakes are commonly recommended for athletes of various sports, including strength trainees, to optimize performance. However, the effect of carbohydrate intake on strength training performance has not been systematically analyzed. A systematic literature search was conducted for trials that manipulated carbohydrate intake, including supplements, and measured strength, resistance training or power either acutely or after a diet and strength training program. Studies were categorized as either (1) acute supplementation, (2) exercise-induced glycogen depletion with subsequent carbohydrate manipulation, (3) short-term (2-7 days) carbohydrate manipulation or (4) changes in performance after longer-term diet manipulation and strength training. Forty-nine studies were included: 19 acute, six glycogen depletion, seven short-term and 17 long-term studies. Participants were strength trainees or athletes (39 studies), recreationally active (six studies) or untrained (four studies). Acutely, higher carbohydrate intake did not improve performance in 13 studies and enhanced performance in six studies, primarily in those with fasted control groups and workouts with over 10 sets per muscle group. One study found that a carbohydrate meal improved performance compared to water but not in comparison to a sensory-matched placebo breakfast. There was no evidence of a dose-response effect. After glycogen depletion, carbohydrate supplementation improved performance in three studies compared to placebo, in particular during bi-daily workouts, but not in research with isocaloric controls. None of the seven short-term studies found beneficial effects of carbohydrate manipulation. Longer-term changes in performance were not influenced by carbohydrate intake in 15 studies; one study favored the higher- and one the lower-carbohydrate condition. Carbohydrate intake per se is unlikely to strength training performance in a fed state in workouts consisting of up to 10 sets per muscle group. Performance during higher volumes may benefit from carbohydrates, but more studies with isocaloric control groups, sensory-matched placebos and locally measured glycogen depletion are needed.

Review
This review summarises the present knowledge of acute compartment syndrome, which is a time-critical diagnosis threatening both life and limb of the affected patients. Acute compartment syndrome is a clinical diagnosis, which in equivocal cases can be supported by direct intra-compartmental pressure measurement and laboratory values. Imaging can detect fractures; and non-invasive monitoring is under investigation but has not yet found clinical use. The treatment is a surgical fasciotomy, and this should be performed acutely. If diagnosis is made more than 24-48 hours after onset of symptoms, non-operative treatment should be considered.

We hereby describe a case of an acutely ill 41-year-old male without any medical history who presented with an acute abdomen in the emergency department. An abdominal CT showed a dissection of the coeliac trunk and infarction of the spleen. Because of a presumed diagnosis of vasculitis he was started on high dose IV steroids. However, after additional testing the diagnosis of segmental arteriolar Mediolysis (SAM) was made. In this case report we describe the presentation, diagnosis, treatment and follow-up of this patient and provide the readers with background about common differential diagnosis and criteria for diagnosing SAM.

Review
Stroke is a leading cause of morbidity and mortality in the United States. Whether hemorrhagic or ischemic, stroke leads to severe long-term disability. Prior to the mid-1990s, the treatment offered to a patient who presented with an acute stroke was mainly limited to antiplatelets. The lack of adequate treatment, in particular, one without reperfusion contributed to the disability that ensued. There have been many advances in stroke care within the past two decades, especially with the acute management of ischemic stroke. Even with these advances, it is quite alarming that only a fraction of patients receives acute stroke treatment. Numerous trials were conducted to broaden treatment eligibility in hopes that more patients can be treated acutely and safely. These trials have tested both the time window for IV tPA and endovascular therapy (EVT). Acute stroke management is moving from a universal time window approach to a concept of tissue preservation. Specifically, preserving cerebral blood flow, the penumbra, and reducing the risk of a second event. This movement is being executed through the use of multimodal CT and MRI, as well as individualizing treatment to our patients. Minimizing the initial effect of stroke changes the outcome and leads to an increased likelihood of functional independence. In this review, we discuss the recent updates of acute ischemic stroke management in regards to mechanical thrombectomy as well as thrombolytics including tenecteplase.

Haemorrhoids are considered among the most frequent proctologi-cal condition at a general practitioner (GP) practice. Acute prolapse of internal haemorrhoids is presented with oedema, inflammation and acute pain. The application of granulated sugar on swollen hae-morrhoids leads to an immediate reduction of their edema and to the patient's relief. After the topical application of sugar, haemorrhoids begin to shrink immediately and edema is drastically reduced, while haemorrhoidal tissue can easily retracted back into the anal canal. The method is a cheap, quick and painless way to control the worsening symptoms such as swelling, bleeding and irritation. In addition, this method can easily be applied in the GP practice without the necessity of any form of anaesthesia.

Post-emetic purpura is an often-forgotten cause of facial rash in the acute setting and can often be mistaken for more dangerous etiologies. We present a case of a child recently treated with trimethoprim/sulfamethoxazole for impetigo who demonstrated a new rash after multiple episodes of vomiting. Lab workup, in conjunction with patient history and lesion location, pointed toward a diagnosis of post-emetic purpura. Careful consideration of the history, physical examination findings, location of the lesion, and laboratory findings are essential for diagnosing post-emetic purpura and differentiating it from other etiologies acutely.
