Sleep-Wake Rhythm and Oscillatory Pattern Analysis in a Multiple Hit Schizophrenia Rat Model (Wisket).

Electroencephalography studies in schizophrenia reported impairments in circadian rhythm and oscillatory activity, which may reflect the deficits in cognitive and sensory processing. The current study evaluated the circadian rhythm and the state-dependent oscillatory pattern in control Wistar and a multiple hit schizophrenia rat model (Wisket) using custom-made software for identification of the artifacts and the classification of sleep-wake stages and the active and quiet awake substages. The Wisket animals have a clear light-dark cycle similar to controls, and their sleep-wake rhythm showed only a tendency to spend more time in non-rapid eye movement (NREM) and less in rapid eye movement (REM) stages.

Impaired pupillary control in "schizophrenia-like" WISKET rats.

Patients with schizophrenia show impairments in autonomic regulation, including pupillomotor control. The aim of this study was to explore the changes of pupillary light reflex in a new substrain (WISKET) with several schizophrenia-like alterations. Male WISKET rats housed individually (for four weeks) and treated with ketamine (for 3 × 5 days) after weaning and naive group-housed Wistar rats (controls) were involved in the study.

Intramuscular Lipoma of the Flexor Hallucis Brevis Muscle.

An intramuscular lipoma is a deep-seated, rare, benign mesenchymal tumor that arises in skeletal muscle. These soft-tissue masses are rarely reported in the foot. We describe an unusual case of an intramuscular lipoma of the flexor hallucis brevis muscle.

Treatment of a High-Risk Diabetic Patient with Peripheral Vascular Disease and Osteomyelitis.

We report a case of calcaneal osteomyelitis that was surgically resected from a patient with diabetes and peripheral vascular disease. A 91-year-old male with history of type 2 diabetes, peripheral vascular disease, balloon angioplasty, and recent (2 months ago) stent of the superficial femoral artery presented to the emergency department with a left heel wound infection probed to bone. The patient reported having been on intravenous Zosyn for several months via an outside infectious disease provider for clinical suspicion of osteomyelitis, but noted no improvement.

Manifestation of an abdominal immune reconstitution inflammatory syndrome associated with a nontuberculous mycobacterial infection - a case report.

Immune reconstitution inflammatory syndrome (IRIS) is an inflammatory reaction in HIV-infected patients after initiation of antiretroviral therapy. It results from restored immunity to specific infectious or non-infectious antigens. We describe the case of a 47-year-old female patient who presented with an unspecific painful pressure in the abdomen and weight loss that was diagnosed as intra-abdominal (unmasking) IRIS due to nontuberculous mycobacterial infection (Mycobacterium avium complex).
