Molecule limits heart attack damage in mice

Conclusion This laboratory-based research in mice, which used a simulation designed to mimic the effects of a heart attack, appears to show that the molecule MitoSNO can prevent some of the heart tissue damage of a heart attack and the consequences of the return of blood to the heart (reperfusion). It is important to remember this was a small, early study in mice. Further studies in rodents would be needed to confirm these initial findings as true and accurate. Furthermore, this study was carried out in mice and the results may not be the same for people. Research in humans would be needed to understand fully the human biological processes involved and to establish whether MitoSNO is effective or safe when used in a similar way for real people. These experiments would need to include a rigorous assessment of the safety of the molecule. Despite the limitations, this intriguing research does highlight a potential biological target for further research. Ultimately, researchers hope to harness the protective effects of MitoSNO to reduce the damage in, and therefore aid the recovery of, people who have recently suffered heart failure due to lack of oxygen. Heart failure can have a significant adverse impact on quality of life so any treatment that can prevent or repair damage to the heart would be very valuable. Analysis by Bazian.

The objective of this study was to examine the usefulness of these less invasive small-bore aspiration catheters for drainage of pneumothorax.MethodsBaseline characteristics and laboratory test data at admission of 70 patients who were admitted to and underwent drainage treatment for pneumothorax at our hospital between April 2011 and February 2017 were retrospectively reviewed based on their medical records. The primary endpoints were factors associated with drainage treatment failure, and baseline characteristics and laboratory test data were compared between those treated with a small-bore aspiration catheter and those ...

Berrigan, Curtis Whitehair, Richard ZorowitzAbstractDry needling is a procedure commonly performed for the relief of myofascial pain disorders. The procedure is generally well tolerated. Adverse events often are mild, but severe complications have been reported. This case report describes an acute spinal epidural hematoma as a complication of dry needling. It is a reminder to the performing physician or therapist to take specific precautions when placing a needle near the spine. Sudden onset of neuropathic pain post-needling therapy in and aro...

We present a 31 year-old woman with T3 AIS A spinal cord injury who developed recurrent AD while receiving duloxetine and amitriptyline combination therapy for neuropathic pain. After excluding other AD generators, duloxetine was discontinued and the AD episodes resolved. While secondary hypertension is a known side effect of amitriptyline and duloxetine, neither drug has been previously associated with AD. One potential mechanism for inhibition of duloxetine metabolism is discussed. Unexplained AD in at-risk patients receiving duloxetine and amitriptyline should prompt consideration of an adverse reaction to combination therapy.

We present a case of 20-year-old woman who presented with a large pedunculated skin covered mass lesion arising from the left thigh, measuring 40  × 25 cm, with no history of pain or skin ulceration and a feeling of a lump with dragging pain in the left side of the abdomen for about 7 years. Subsequently, ultrasound, contrast-enhanced computed tomography, and magnetic resonance imaging of abdomen and left thigh region were carried out. The lesion was broad-based toward the left upper thigh with a central core of interspersed fat supplied by branches of the superficial and deep femoral arteries...

We present a case of a 24-year-old female with known lymphangiomatosis, presenting with acute onset of lower extremity paresthesias, weakness, and new urinary retention. MRI of the pelvis revealed lymphangiomatosis of the sacral plexus, which has not been previously reported. We will review the clinical and imaging manifestations of lymphangiomatosis and provide a differential diagnosis for masses of the lumbosacral plexus. Although lower extremity pain and weakness encountered in the emergency department or outpatient setting is most frequently caused by lumbar spine pathology, occasionally, abnormalities of the lumbosacr...

We report an immunocompetent patient who presented with a rare form of cutaneous VZV infection of the upper leg characterized by vasculitic changes of the small vessels without typical herpetic epidermal features or neural involvement. Intriguingly, the vasculitis appeared prior to the characteristic vesicular rush without any pain symptoms. Because VZV can cause vasculopathic damage mainly within the central nervous system in immunocompetent and immunosuppressed patients, we recommend continuous clinical controls to recognize central symptoms that are related to VZV vasculopathy or giant cell arteriitis.

We report a new case of BCC-MD occurring in a renal-transplant recipient and review the relevant literature. A 75-year-old white man who had received a renal allograft 7 years ago developed a tumor on the left temple clinically suggestive of basal-cell carcinoma. Microscopically, the tumor associated features typical of basal-cell carcinoma (basaloid lobules with peripheral palisading and clefting) and pilomatricoma (presence of shadow/ghost cells). The 2 tumor components expressed variably beta-catenin, HEA/Ber-EP4, CD10, PHLDA-1, MIB-1/Ki67, calretinin, and bcl-2. BCC-MD has no distinctive clinical features. It affects p...
