Femoral triangle block and local infiltration analgesia are two effective analgesic techniques after anterior cruciate ligament reconstruction. Recently, the iPACK block (infiltration between the popliteal artery and the capsule of the posterior knee) has been described to relieve posterior knee pain. This randomized controlled triple-blinded trial tested the hypothesis that the combination of femoral triangle block and iPACK provides superior analgesia to local infiltration analgesia after anterior cruciate ligament reconstruction.

Few pharmacological interventions are available for cancer-associated anorexia and cachexia. Mirtazapine has been suggested for use in cancer-associated anorexia and cachexia.

We present a 24-year-old man with a 2-year history of progressive right-sided monocular vision loss with no other symptoms. An MRI showed a meningioma compressing the right optic nerve and the cavernous sinus. The tumour was partially resected. Eight days after discharge the patient was admitted with fever, a severe stabbing headache, insomnia, nausea and vomiting. A FilmArray panel and a cerebral biopsy were performed which were positive for herpes simplex virus 1 (HSV-1). An MRI of the brain showed asymmetric bilateral lesions in the frontobasal region with predominance of the right side. Acyclovir was started and continued until completing 21 days. A month after discharge, he started experiencing insomnia, trichotillomania, limb tremor, persistence of abulia, apathy and emotional lability. An HSV-1 encephalitis relapse was suspected, acyclovir and foscarnet were started. Due to the poor response to antiviral therapy CSF was tested, which was positive for anti-NMDA receptor encephalitis. A treatment course of intravenous immunoglobulin was started with a favourable outcome.

Fear of movement-related pain is known to disturb the process of motor preparation in patients with chronic pain. In the present study, we aimed to clarify the neural mechanisms underlying the influence of fear movement-related pain on motor preparatory brain activity using Libet's clock and electroencephalography (EEG). Healthy participants were asked to press a button while watching a rotating Libet's clock-hand, and report the number on the clock ("W time") when they made the "decision" to press the button with their right index finger. Immediately after pressing the button, a painful electrical stimulus was delivered to the dorsum of the left hand, causing participants to feel fear of movement (button press-related pain). We found that fear of movement-related pain caused the W time to be early, and that the amplitudes of readiness potentials (RPs) increased after awareness of motor intention emerged. In addition, fear of movement-related pain caused over-activation of the medial frontal cortex, supplementary motor area, cingulate motor area, and primary motor cortex after participants became aware of their motor intention. Such over-activation might result from conflict between the unrealized desire to escape from a painful experience and motivation to perform a required motor task.

Scleritis is a rare disease and the incidence of bilateral posterior scleritis is even rarer. Unfortunately, misdiagnosis of the latter is common due to its insidious onset, atypical symptoms, and varied manifestations. We report here a case of bilateral posterior scleritis that presented with acute eye pain and intraocular hypertension, and was initially misdiagnosed as acute primary angle closure. Expanding the literature on such cases will not only increase physicians' awareness but also help to improve accurate diagnosis.

Pheochromocytoma is a rare endocrine tumor arising from chromaffin cells and having extensive and profound effects on the cardiovascular system by continuously or intermittently releasing catecholamines. The clinical manifestations of pheochromocytoma are diverse, and the typical triad, including episodic headache, palpitations, and sweating, only occurs in 24% of pheochromocytoma patients, which often misleads clinicians into making an incorrect diagnosis. We herein report the case of a patient with intermittent chest pain and elevated myocardial enzymes for 2 years who was diagnosed with pheochromocytoma.

Amebic colitis is an infection caused by and most commonly observed in regions with poor sanitation. It is also seen as a sexually transmitted disease in developed countries. While amebic colitis usually has a chronic course with repeated exacerbations and remissions, it may also manifest as a fulminant form that rapidly progresses and leads to severe, life-threatening complications, such as intestinal perforation, peritonitis, and sepsis, that have a high mortality rate.

Compared with open mesh repair, transabdominal preperitoneal (TAPP) hernioplasty results in less chronic postoperative inguinal pain and faster postoperative recovery. However, it may still lead to rare but serious complications. Here we report a case of intestinal volvulus with recurrent abdominal pain as the only clinical symptom, which occurred 3 mo after TAPP repair for bilateral inguinal hernia.

A high degree of vigilance is warranted for a spinal infection, particularly in a patient who has undergone an invasive procedure such as a spinal injection. The average delay in diagnosing a spinal infection is 2-4 mo. In our patient, the diagnosis of a spinal infection was delayed by 1.5 mo.

Measurement of perioperative quality of recovery (QoR) is an important tool in improving the patient's perioperative experience. By making use of the Quality of Recovery-15 (QoR-15) questionnaire, this study aimed to measure the QoR on day 1 in patients following elective and semiurgent orthopedic surgery at an academic hospital. A secondary aim was to determine factors that may influence the QoR.
