Noise in intensive care units (ICUs) has always been a problem, but noise above the recommended range affects not only the patient but staff as well. It is clear that some noise in the ICU is inevitable, but exceeding the normal range brings various physiologic and psychologic changes, which directly affect health. This review presents a synthesis of noise sources in the ICU and the potential interventions designed to attenuate noise and protect patients.

Intraventricular pilocytic astrocytomas are a rare occurrence, accounting for approximately 4% -15.6% of all pilocytic astrocytomas .The aim of the study was to describe the radiology, surgical management and outcome in 15 patients with histopathologically proven intraventricular pilocytic astrocytoma(IVPA).

Prospective observational cohort study. To determine whether biofilms exist on spinal instrumentation recovered during revision surgery in which microbial cultures were negative. Biofilm bacteria are extremely difficult to detect by conventional culture methods used in the standard hospital setting. Chronic infections in which bacteria form biofilms have been demonstrated to slow healing and prevent bony fusion. These slime encased microbial communities serve to isolate the bacteria from the body's immune responses, while simultaneously providing metabolic resistance to antimicrobial therapy. Traditional debridement wound cultures were taken from each specimen and sent for microbiological analyses. Bacterial DNA testing was performed using polymerase chain reaction (PCR) electrospray ionization-mass spectrometry (ESI-MS). Based on the PCR/ESI-MS results, specific crossed immune electrophoresis was used to detect the bacterial species within biofilms observed on the removed instrumentation. In addition, fluorescent hybridization (FISH) probes corresponding to the bacterial species identified by PCR/ESI-MS were used with confocal microscopy to visualize and confirm the infecting bacteria. Fifteen patients presented for surgical revision of thoracolumbar spinal implantation: four for clinical suspicion of infection, six for adjacent segment disease (ASD), one with ASD and pseudoarthrosis (PA), three with PA, and one for pain. Infections were confirmed with PCR/ESI-MS for all four patients who presented with clinical infection, and for five of the patients for whom infection was not clinically suspected. Of the presumed non-infected implants, 50% demonstrated the presence of infectious biofilms. Half of the revisions due to pseudoarthrosis were shown to harbour biofilms. The revisions that were performed for pain demonstrated robust biofilms but did not grow bacteria on traditional culture media. Culture is inadequate as a diagnostic modality to detect indolent/subclinical biofilm infections of spinal instrumentation. The PCR/ESI-MS results for bacterial detection were confirmed using species-specific microscopic techniques for both bacterial nucleic acids and antigens. Biofilms may contribute to pseudoarthrosis and back pain in postoperative wounds otherwise considered sterile.

Onychomykose (OM) und Tinea pedis (TP) sind häufige Pilzinfektionen der Haut. Aktuell basiert die Diagnose vornehmlich auf mikroskopischem Direktnachweis und/oder Kultur. Beide Methoden haben jedoch eine geringe bis mäßige Sensitivität und benötigen teilweise mehrere Wochen, bis endgültige Laborergebnisse vorliegen. Um die Diagnose kutaner Pilzinfektionen zu verbessern, wurden PCR-basierte Methoden entwickelt. Hier haben wir hier die Sensitivität und Spezifität einer Chip-basierten Multiplex-PCR mit mikroskopischen Direktnachweis und verglichen.

Cluster headaches are a series of short, excruciating, and unilateral pain that happens for a short period at a time over days, weeks, or months and may awake people from sleep. It is situated behind, in, or around one eye only with possible radiation to the forehead at the same side. Cluster headache is characterized by many ocular features. However, extraocular muscle involvement is unusual in this type of headache. We present a case of chronic cluster headache associated with diplopia due to oculomotor nerve palsy in a 24-year-old man, which responded successfully to oral steroid. This presentation is rare. Therefore, ophthalmologists and neurologists should consider it in their list of a differential diagnosis. A short course of oral prednisolone has a role in the management of patients in such cases.

This study measured the prevalence and impact of nonadherence to clinical practice guidelines (CPGs) that recommend using nonpharmacological and nonopioid treatments such as nonsteroidal anti-inflammatory drugs (NSAIDs) before considering opioids in patients with chronic low back pain.

The culprit of trigeminal neuralgia (TGN) may occur at any point between the nerve's root entry zone (REZ) and Meckel's cave. Meckel's cave meningoencephaloceles are rare middle cranial fossa defects that usually remain asymptomatic but may contain prolapsed trigeminal nerve rootlets and result in TGN. Their management and surgical outcomes remain poorly understood.

Laparoscopic appendectomy (LA) is claimed to require less analgesic and allow for a faster return to work. This study examines whether these benefits hold true in Asian patient populations.

An 8.75-year-old male neutered Burmese cat was referred for treatment of pyothorax. The cat was responsive, cardiovascularly stable and tachypnoeic (40 breaths/min) on arrival. Medical management of pyothorax was initiated, bilateral thoracic drains were placed and thoracic lavage using aliquots of saline 0.9% was performed every 4 h. Regional analgesia was provided using 1 mg/kg of intrapleural bupivacaine divided equally between the left and right hemithoraxes every 6 h. On the second day of hospitalisation, the cat developed hypersalivation, mydriasis and tonic-clonic seizure activity 25 mins after accidental intrapleural administration of a 10 mg/kg bupivacaine overdose. Cardiovascular compromise was also noted; the cat became bradycardic (120 beats/min) and blood pressure decreased to 110 mmHg. Clinical signs resolved after administration of intravenous lipid emulsion (ILE) as an intravenous (IV) bolus (1.5 ml/kg over 5 mins), followed by a continuous rate infusion (0.25 ml/kg/min over 25 mins). Local anaesthetic intrapleural anaesthesia was discontinued. There was recrudescence of clinical signs 10 h post-overdose and repeat ILE 20% infusion was required. The cat was discharged with no ongoing complications.

Over 300,000 rotator cuff repairs are performed annually in the United States, where the annual financial burden of managing shoulder pain has been estimated to be $3 billion. Despite advances in surgical techniques, retear rates range from 39% to 94%. Partial-thickness tears are approximately twice as common as full-thickness tears and can lead to considerable pain and loss of function. Although some partial-thickness tears can be treated nonoperatively, spontaneous healing is unlikely when >50% of the bursal/articular-sided tendon thickness is involved, and thus nonoperative treatment would be unsuccessful. Regeneten (Smith & Nephew) is a bioinductive type-1 collagen implant that can be utilized to repair a partial-thickness rotator cuff tear without formal tendon-bone reattachment. Because this implant does not require tendon-bone reattachment, treatment does not typically entail prolonged rehabilitation. At 2 years postoperatively, this implant has been shown to significantly improve functional outcomes and tendon thickness without any serious adverse events.
