    The antibiotic minocycline, which is used in the treatment of acne, has been associated with various pulmonary complications such as pulmonary lupus and hypersensitivity pneumonitis. We now report a particularly severe case of minocycline-related pulmonary toxicity that was characterized by a relapsing form of hypersensitivity eosinophilic pneumonia complicated by acute respiratory failure.

    A patient is reported who developed dyspnoea, fever, pleuritic chest pain and a non-productive cough following treatment with minocycline for 9 days. The chest radiograph showed an interstitial pattern and there was a peripheral eosinophilia. A diagnosis of hypersensitivity pneumonitis attributable to minocycline was made. The disease responded quickly to withdrawal of the drug. This observation shows that minocycline, despite its mild toxicity profile, can give rise to serious adverse effects.

    Minocycline belongs to the second generation class of cyclines. It was synthesized in 1967 and marketed in 1972. Minocycline has an antiinfectious activity with a spectrum similar to that of other cyclines, notably against Chlamydias, Treonema and Proprionibacterium acenes. The antiinflammatory activity is associated with this antiinfectious action is greater than that of first generation cyclines with specifically a modulator effect on epidermal cytokines. The pharmokinetics of minocycline is characterized by an excellent absorption, a long half-life and an important lipophilic property inducing good tissue distribution. Clinical trials of minocycline have mainly been performed in sexually transmissible diseases and in acne, a field where randomized studies are the most frequent. These trials show that the effect of minocycline is not stronger than first generation cyclines or doxycycline, but that the action is quicker than that of tetracycline at the dose of 500 mg a day. Minocycline is also efficient in nocardiasis, mycobacteriosis, leprosy, Lyme disease, pyoderma gangrenosum, autoimmune bullous dermatitis, Carteaud disease, and prurigo. However, the effect of minocycline in these different conditions has always been evaluated in open trials with a small number of patients. The usual side effects of cyclines, i.e. digestive problems, fungal infections, are less frequent than with first generation cyclines. No photosensitivity has been demonstrated although pigmentations have been described. Dizziness is a specific side effect of minocycline. Furthermore, rare but severe side effects have been reported, including hypersensitivity syndrome, autoimmune hepatitis, and lupus. Regular indications for minocycline in dermatology are acne and three sexually transmissible diseases (mycoplasm, chlamydia, treponema). Proposed dosage is 100 mg per day in sexually transmissible disease with a reduction to 50 mg per day after 15 days in acne.

    Minocycline is the most commonly used systemic antibiotic in the long-term treatment (weeks to months) of severe acne vulgaris. Currently much attention is being paid in the Dutch and international literature to the safety of minocycline, after several reports on serious adverse events. The clinical efficacy of minocycline in the treatment of acne vulgaris is better than that of tetracycline and equal to that of doxycycline. The serious adverse events of minocycline therapy described consist of hyperpigmentation of various tissues, autoimmune disorders (systemic lupus erythematosus, autoimmune hepatitis) and serious hypersensitivity reactions (hypersensitivity syndrome reaction, pneumonitis and eosinophilia, and serum sickness-like syndrome). In relation to the number of prescriptions, the number of serious adverse events of minocycline described is small. However, it is very important that prescribing doctors should be aware of the possibility of these adverse events occurring during long-term minocycline therapy and able to recognize the characteristic symptoms at an early stage.

    Glia, particularly astrocytes and microglia, are known to play an important role in central sensitization and are strongly implicated in the exaggerated pain states. In the present study, we determined the effect of minocycline, an inhibitor of microglial activation, in acute nociception, peritonitis, and the development and maintenance of hypersensitivity following chronic constriction injury of the sciatic nerve in rats. A single dose of minocycline (30 or 100 mg/kg, i.p.) 30 min before acetic acid or zymosan injection did not attenuate the nociceptive behavior in mice. It had no effect on the early events of peritoneal inflammation (vascular permeability, inflammatory cell infiltration, and release of pro-inflammatory cytokines) in acetic acid or zymosan-injected mice. In addition, minocycline (30 or 100 mg/kg, i.p.) did not alter basal nociceptive responses in the tail immersion test. Chronic administration of minocycline (10 or 30 mg/kg, i.p.) for 7 days started before nerve injury significantly prevented the development of neuropathic pain, interestingly, it further delayed the development of hypersensitivity. In contrast, single injection of minocycline failed to reverse hypersensitivity when administered during the development of neuropathic pain. No significant effects were observed on hypersensitivity when treatment was started once neuropathic state was established. Pre-treatment, but not post-treatment, with minocycline markedly attenuated increased pro-inflammatory cytokines release and oxidative and nitrosative stress in mononeuropathic rats. These results suggest that minocycline had no effect on acute peritoneal inflammation, nociception, and chronic administration of minocycline when started early before peripheral nerve injury could attenuate and further delays the development of neuropathic pain. Concluding, this study clearly shows minocycline, an inhibitor of microglial activation, by inhibiting the release of pro-inflammatory mediators and

    Acute eosinophilic pneumonia (AEP) can be a challenging diagnosis and is often initially misdiagnosed as one of the more common pneumonia syndromes such as acute respiratory distress syndrome. Early bronchoalveolar lavage (BAL) is critical in distinguishing the diagnosis to initiate proper management. The etiology of AEP is unknown, though many drugs have been implicated, including minocycline. Minocycline is commonly used for pneumonia, acute bronchitis, urinary tract infections, and acne and is likely the cause of AEP in our patient. There are 26 case reports of minocycline-induced AEP. In most cases, outcomes were favorable and symptoms rapidly resolved upon discontinuation of minocycline, with 11 cases employing steroids, one case twelve hours of CPAP and another 5 days of intubation. None resulted in mortality. Although it is difficult to evaluate without further studies, steroids should be recommended for minocycline-induced AEP, especially for those with severe or persistent symptoms. PMID:26236618

    Minocycline is a semi-synthetic tetracycline antibiotic effective against a wide range of aerobic and anaerobic Gram-positive and Gram-negative bacteria. It is highly active in the pilosebaceous complex, due to its great lipophilicity, and therefore it has been used in the treatment of moderate to severe papulo-pustular acne for a long time. It has an optimal therapeutic range and the percentage of P. acnes resistant strains are still inferior to 5%. Besides the antimicrobial activity, minocycline has an anti-inflammatory action, due to the reduction in neutrophilic chemotaxis, the inhibitory effect on pro-inflammatory cytokines, and the reduction in sebum free fatty acids and bacterial lipases. In 2006 the Food and Drug Administration (FDA) approved a new extended-release formulation of minocycline. This formulation allowed the reduction of some dose-related adverse events, such as those affecting the vestibular system. Besides the dose-related events (nausea, vomiting, and dizziness), minocycline is also known to induce hyperpigmentation, even if less frequently than doxycycline, and is rarely responsible for autoimmune disorders, hypersensitivity reactions, and serum sickness-like reactions. The latest guidelines in the treatment of acne recommend a dose of 50-100 mg, once or twice a daily for the non-modified release minocycline, and 1 mg/kg daily for the new extended-release formulation. This agent is most appropriately used in combination with a topical regimen containing benzoyl peroxide and/or retinoid.

    Aim To evaluate the clinical impact, aqueous tear parameters, and meibomian gland morphology in patients with primary meibomianitis before, during, and 3 months after a course of oral minocycline. Methods 16 patients were prospectively enrolled, 11 male and five female (mean age 69 years old). Each patient received routine clinical evaluations before, after 3 months therapy, and at 6 month study follow up visit. The clinical appearance, tear volume, flow and turnover, evaporation, Schirmer I test, meibomian gland dropout, lissamine green staining, and bacteriology wer evaluated. Results Improvement was observed in clinical signs of meibomianitis at the second and third visits. Microbial culture findings improved. Decreased aqueous tear volume and flow, and increased evaporation rate range at 35–45% relative humidity (RH) (p<0.05) were also detected. Other related tear parameters did not change. Meibomian gland dropout showed no improvement. Conclusions 3 months of oral minocycline resulted in clinical improvements in all meibomianitis signs that persisted for at least 3 months after discontinuation despite decreased aqueous tear volume and flow with increased evaporation (35–45% RH). However, there was improvement in the turbidity of secretions. Short term minocycline therapy probably has efficacy in the management of meibomianitis that extends beyond eradication of bacteria.

    Oral antibiotics continue to play an important role in the treatment of moderate-to-severe acne. Minocycline is widely used in moderate-to-severe acne. Minocycline has anti-inflammatory properties, activity against Propionibacterium acnes and lipophilicity. An extended-release formulation of minocycline has been introduced. Extended-release minocycline is not bioequivalent to nonmodified release minocycline products and exhibits dose-proportional pharmacokinetics. Food or dairy products did not influence absorption. Efficacy is not dose-dependent, while the incidence of acute vestibular adverse events increases with dose suggesting an optimal dose of 1mg/kg. In two Phase 3 clinical trials, mean percent improvement in inflammatory lesions after 12 weeks of treatment with extended-release minocycline was 43.1 and 45.8 percent compared to 31.7 and 30.8 percent with placebo (P=0.001 and P<0.001, respectively) while the incidence of acute vestibular adverse events was comparable to placebo.

    Subcortical ischemic vascular dementia (SIVD) caused by chronic cerebral hypoperfusion develops with progressive white matter and cognitive impairments, yet no effective therapy is available. We investigated the temporal effects of minocycline on an experimental SIVD exerted by right unilateral common carotid arteries occlusion (rUCCAO). Minocycline treated at the early stage (day 0-3), but not the late stage after rUCCAO (day 4-32) alleviated the white matter and cognitive impairments, and promoted remyelination. The actions of minocycline may not involve the inhibition of microglia activation, based on the effects after the application of a microglial activation inhibitor, macrophage migration inhibitory factor, and co-treatment with lipopolysaccharides. Furthermore, minocycline treatment at the early stage promoted the proliferation of oligodendrocyte progenitor cells (OPCs) in subventricular zone, increased OPC number and alleviated apoptosis of mature oligodendrocytes in white matter. In vitro, minocycline promoted OPC proliferation and increased the percentage of OPCs in S and G2/M phases. We provided direct evidence that early treatment is critical for minocycline to alleviate white matter and cognitive impairments after chronic cerebral hypoperfusion, which may be due to its robust effects on OPC proliferation and mature oligodendrocyte loss. So, early therapeutic time window may be crucial for its application in SIVD.

    There is only 1 US Food and Drug Administration-approved drug for acute ischemic stroke: tissue plasminogen activator (tPA). Due to a short time window and fear of intracerebral hemorrhage (ICH), tPA remains underutilized. There is great interest in developing combination drugs to use with tPA to improve the odds of a favorable recovery and to reduce the risk of ICH. Minocycline is a broad spectrum antibiotic that has been found to be a neuroprotective agent in preclinical ischemic stroke models. Minocycline inhibits matrix metalloproteinase-9, a biomarker for ICH associated with tPA use. Minocycline is also an anti-inflammatory agent and inhibits poly (ADP-ribose) polymerase- 1. Minocycline has been safe and well tolerated in the clinical trials conducted to date. PMID:20575623

    An 18-year-old Japanese girl had received oral minocycline 200mg daily for treatment of acne vulgaris since 16 years old. She had a fever three months before admission, followed by joint pains in her knees, elbows and several proximal interphalangeal joints one month before admission. She was referred to our hospital because of a high serum level of anti-DNA antibody. She had already discontinued oral minocycline five weeks before admission, because she missed her medication refilled. On admission, the arthralgia and fever spontaneously resolved, and there were no laboratory evidence of hypocomplementemia and cytopenia. She had neither erythema nor internal organ involvements. Because her symptoms subsided spontaneously after the cessation of minocycline, she was considered to have drug-induced lupus. Both the arthralgia and fever did not relapse, and anti-ds DNA antibody returned to normal during a follow-up period without treatment. There are few reports of drug-induced lupus caused by minocycline in Japan. This case highlights the importance of considering minocycline-induced lupus.

    The tetracycline antibiotics have pleiotropic anti-inflammatory properties that may explain their therapeutic benefit in rheumatoid arthritis and acne. As these agents suppress both cellular and humoral immune responses, they may be of benefit in treating asthma and other allergic disorders. The purpose of this study was to determine whether minocycline therapy of asthma has steroid sparing effects beyond its inherent antibiotic properties. Adult asthmatic patients (n = 17) were treated with minocycline 150 mg p.o. twice daily or placebo for 8 weeks in a randomized, double-blind, placebo-controlled crossover study. Patients were evaluated for clinical improvement in oral steroid requirements, spirometry, and symptom scores (Asthma Quality of Life Questionnaire). They underwent assessment for preexisting infection (CT facial sinuses, Chlamydia pneumoniae nasopharyngeal culture, and C. pneumoniae and Mycoplasma pneumoniae serology). Minocycline use was associated with a 30% reduction in mean daily prednisone use compared with placebo (8.8 mg versus 14.4 mg, respectively; p = 0.02). Pulmonary function testing showed improvement in forced vital capacity (FVC; percent predicted; p = 0.03) and improvement in actual FVC and forced expiratory volume in 1 second (percent predicted) approached statistical significance (p = 0.05 and 0.08, respectively). Minocycline treatment was associated with significant improvement in asthma symptoms brought on by environmental triggers (p = 0.01). This preliminary study of minocycline therapy showed oral steroid-sparing properties for those with moderate persistent and severe persistent asthma.

    Increasing evidence suggests that the tetracycline antibiotic minocycline has neuroprotective effects and is a potential treatment for schizophrenia. However, the mechanisms of action of minocycline in the CNS remain elusive. The aim of this study was to investigate the effects of minocycline on brain morphology and cerebral perfusion in patients with recent-onset schizophrenia after 12months of a randomized double-blind, placebo-controlled clinical trial of minocycline add-on treatment. This study included 24 outpatients with recent-onset schizophrenia randomized for 12months of adjuvant treatment with minocycline (200mg/d) or placebo. MRI (1.5T) and [(99m)Tc]-ECD SPECT brain scans were performed at the end of the 12-month of trial. Between-condition comparisons of SPECT and MRI brain images were performed using statistical parametric mapping and analyzed by voxel-based morphometry (VBM). Minocycline adjuvant treatment significantly reduced positive and negative symptoms when compared with placebo. The VBM analysis of MRI scans showed that the patients in the placebo group had significant lower gray matter volumes in the midposterior cingulate cortex and in the precentral gyrus in comparison with the patients in the minocycline group. In addition, a decreased ECD uptake in the minocycline condition was observed in fronto-temporal areas. These results suggest that minocycline may protect against gray matter loss and modulate fronto-temporal areas involved in the pathophysiology of schizophrenia. Furthermore, minocycline add-on treatment may be a potential treatment in the early stages of schizophrenia and may ameliorate clinical deterioration and brain alterations observed in this period.

    In addition to its antimicrobial activity, minocycline exerts anti-inflammatory effects in several disease models. However, whether minocycline affects the pathogenesis of inflammatory bowel disease has not been determined. We investigated the effects of minocycline on experimental colitis and its underlying mechanisms. Acute and chronic colitis were induced in mice by treatment with dextran sulfate sodium (DSS) or trinitrobenzene sulfonic acid (TNBS), and the effect of minocycline on colonic injury was assessed clinically and histologically. Prophylactic and therapeutic treatment of mice with minocycline significantly diminished mortality rate and attenuated the severity of DSS-induced acute colitis. Mechanistically, minocycline administration suppressed inducible nitric oxide synthase (iNOS) expression and nitrotyrosine production, inhibited proinflammatory cytokine expression, repressed the elevated mRNA expression of matrix metalloproteinases (MMPs) 2, 3, 9, and 13, diminished the apoptotic index in colonic tissues, and inhibited nitric oxide production in the serum of mice with DSS-induced acute colitis. In DSS-induced chronic colitis, minocycline treatment also reduced body weight loss, improved colonic histology, and blocked expression of iNOS, proinflammatory cytokines, and MMPs from colonic tissues. Similarly, minocycline could ameliorate the severity of TNBS-induced acute colitis in mice by decreasing mortality rate and inhibiting proinflammatory cytokine expression in colonic tissues. These results demonstrate that minocycline protects mice against DSS- and TNBS-induced colitis, probably via inhibition of iNOS and MMP expression in intestinal tissues. Therefore, minocycline is a potential remedy for human inflammatory bowel diseases.

    Scrub typhus, caused by Orientia tsutsugamushi, has recently emerged in northern China where the disease had not been known to exist. Although doxycycline and azithromycin are the recommended agents for the treatment of scrub typhus, clinical responses depend both on the susceptibilities of various O. tsutsugamushi strains and the severity of the disease. A retrospective analysis was conducted on patients diagnosed with mild scrub typhus from August 2013 to January 2016 in the Affiliated Hospital of Nantong University, northern China. A total of 40 patients who received minocycline treatment and 34 patients who received azithromycin treatment were included in the analysis. All patients except one defervesced within 120 h after initiating antimicrobial therapy. Kaplan-Meier curves in association with log-rank test showed that the median time to defervescence was significantly shorter for the minocycline-treated group than the azithromycin-treated group (P = 0.003). There were no serious adverse events during treatment. No relapse occurred in either group during the 1-month follow-up period. In conclusion, both minocycline and azithromycin are effective and safe for the treatment of mild scrub typhus, but minocycline is more active than azithromycin against O. tsutsugamushi infection acquired in northern China.

    Background Rapid local drug clearance of antimicrobials is a major drawback for the treatment of chronic periodontitis. In the study reported here, minocycline-loaded poly(ethylene glycol)-poly(lactic acid) nanoparticles were prepared and administered locally for long drug retention and enhanced treatment of periodontitis in dogs. Methods Biodegradable poly(ethylene glycol)-poly(lactic acid) was synthesized to prepare nanoparticles using an emulsion/solvent evaporation technique. The particle size and zeta potential of the minocycline-loaded nanoparticles (MIN-NPs) were determined by dynamic light scattering and the morphology of the nanoparticles was observed by transmission electron microscopy. The in vitro release of minocycline from MIN-NPs and in vivo pharmacokinetics of minocycline in gingival crevice fluid, after local administration of MIN-NPs in the periodontal pockets of beagle dogs with periodontitis, were investigated. The anti-periodontitis effects of MIN-NPs on periodontitis-bearing dogs were finally evaluated. Results Transmission electron microscopy examination and dynamic light scattering results revealed that the MIN-NPs had a round shape, with a mean diameter around 100 nm. The in vitro release of minocycline from MIN-NPs showed a remarkably sustained releasing characteristic. After local administration of the MIN-NPs, minocycline concentration in gingival crevice fluid decreased slowly and retained an effective drug concentration for a longer time (12 days) than Periocline®. Anti-periodontitis effects demonstrated that MIN-NPs could significantly decrease symptoms of periodontitis compared with Periocline and minocycline solution. These findings suggest that MIN-NPs might have great potential in the treatment of periodontitis. PMID:25170266

    Tetracycline analogues (TCNAs) have been shown to inhibit matrix metalloproteinases and to induce apoptosis in several cancer cell types. In the present study, the cytotoxic effects of TCNAs doxycycline (DOXY), minocycline (MINO) and chemically modified tetracycline-3 (COL-3) were investigated in the human acute myeloid leukemia HL-60 cell line. Cells were incubated with TCNAs in final concentrations of 0.5-100 µg/ml for 24 h. Viability of the leukemic cells was inhibited in a concentration-dependent manner using resazurin assay. The estimated IC50s were 9.2 µg/ml for DOXY, 9.9 µg/ml for MINO and 1.3 µg/ml for COL-3. All three TCNAs induced potent cytotoxic effects and cell death. Apoptosis, which was assessed by morphological changes and annexin V positivity, was concentration- and time-dependent following incubation with any one of the drugs. TCNAs induced DNA double strand breaks soon after treatment commenced as detected by γH2AX and western blot. The loss of mitochondrial membrane potential (Δψm), caspase activation and cleavage of PARP and Bcl-2 were observed; however, the sequence of events differed among the drugs. Pancaspase inhibitor Z-VAD-FMK improved survival of TCNAs-treated cells and decreased TCNAs-induced apoptosis. In summary, we demonstrated that TCNAs had a cytotoxic effect on the HL-60 leukemic cell line. Apoptosis was induced via mitochondria-mediated and caspase-dependent pathways in HL-60 cells by all three TCNAs. COL-3 exerted the strongest anti-proliferative and pro-apoptotic effects in concentrations that have been achieved in human plasma in reported clinical trials. These results indicate that there is a therapeutic potential of TCNAs in leukemia.

    In recent years, minocycline has become a commonly used agent for the treatment of acne vulgaris and rosacea. With this increased use have come reports of severe and in some cases life-threatening toxicity, often occurring in otherwise healthy young women after prolonged courses of minocycline. These adverse reactions include hepatotoxicity, drug-induced lupus erythematosus, eosinophilic pneumonitis, and hypersensitivity syndrome. We describe a 35-year-old woman who had necrotizing vasculitis of the skin and uterine cervix after 2 years of minocycline therapy for acne vulgaris. Skin and cervical biopsies revealed acute inflammation involving through-and-through necrosis of vessel walls with thrombosis, focal fibrinoid change, and a perivascular lymphohistiocytic infiltrate. The disease fully resolved within 3 months of discontinuance of the minocycline therapy. Patients should be informed of these rare but potentially serious adverse effects before the initiation of minocycline therapy. Early recognition of these complications can result in complete resolution.

    Experimental autoimmune neuritis (EAN) is a widely used animal model of the human acute inflammatory demyelinating polyradiculoneuropathy, which is the most common subtype of Guillain-Barré Syndrome. EAN is pathologically characterized by breakdown of the blood-nerve barrier, infiltration of reactive immune cells, local inflammation, demyelination in the peripheral nervous system and mechanical allodynia. Minocycline is known to have neuroprotective and anti-inflammatory effects. Furthermore, relieve of neuropathic pain following minocycline administration was observed in a variety of animal models. Here, we investigated the effects of minocycline on rat EAN. Suppressive treatment with minocycline (50 mg/kg body weight daily immediately after immunization) significantly attenuated the severity and duration of EAN. Macrophage and T-cell infiltration and demyelination in sciatic nerves of EAN rats treated with minocycline were significantly reduced compared to phosphate-buffered saline (PBS)-treated EAN rats. mRNA expressions of matrix metallopeptidase-9, inducible nitric oxide synthase and pro-inflammatory cytokines interleukin-1 beta and tumour necrosis factor-alpha in EAN sciatic nerves were greatly decreased by administration of minocycline as well. Furthermore, minocycline attenuated mechanical allodynia in EAN rats and greatly suppressed spinal microglial activation. All together, our data showed that minocycline could effectively suppress the peripheral and spinal inflammation (immune activation) to improve outcome in EAN rats, which suggests that minocycline may be considered as a potential candidate of pharmacological treatment for autoimmune-mediated neuropathies.

    Activation of spinal microglia contributes to aberrant pain responses associated with neuropathic pain states. Endocannabinoids (ECs) are present in the spinal cord, and inhibit nociceptive processing; levels of ECs may be altered by microglia which modulate the turnover of endocannabinoids in vitro. Here, we investigate the effect of minocycline, an inhibitor of activated microglia, on levels of the endocannabinoids anandamide and 2-arachidonoylglycerol (2-AG), and the related compound N-palmitoylethanolamine (PEA), in neuropathic spinal cord. Selective spinal nerve ligation (SNL) in rats resulted in mechanical allodynia and the presence of activated microglia in the ipsilateral spinal cord. Chronic daily treatment with minocycline (30 mg/kg, ip for 14 days) significantly reduced the development of mechanical allodynia at days 5, 10 and 14 post-SNL surgery, compared to vehicle-treated SNL rats (P < 0.001). Minocycline treatment also significantly attenuated OX-42 immunoreactivity, a marker of activated microglia, in the ipsilateral (P < 0.001) and contralateral (P < 0.01) spinal cord of SNL rats, compared to vehicle controls. Minocycline treatment significantly (P < 0.01) decreased levels of 2-AG and significantly (P < 0.01) increased levels of PEA in the ipsilateral spinal cord of SNL rats, compared to the contralateral spinal cord. Thus, activation of microglia affects spinal levels of endocannabinoids and related compounds in neuropathic pain states.

  4. The combination of morphine and minocycline may be a good treatment for intractable post-herpetic neuralgia.

    Post-herpetic neuralgia (PHN) is a devastating complication of shingles. The treatment of PHN with traditional pharmaceutical agents has various side effects. Therefore, the treatment of intractable PHN is often very time consuming, mainly because the available treatments often lead to intolerable side effects before the efficient dose can be reached. Opioids such as morphine and oxycodone are the most widely used drugs for the alleviation for severe chronic pain. A number of high quality studies demonstrated that opioids are effective in relieving neuropathic pain including PHN. Yet concerns of misuse, abuse and tolerance of opioids have, however, severely influenced their contribution to neuropathic pain, especially the tolerance that resulted in a loss of drug effect or the necessity for escalating doses to produce pain relief. The glia cells, particularly microglia and astrocytes are thought to play an important role in central sensitization. It is known that activated microglia cells produce NO, cytokines, and cyclooxygenase. All of these chemicals regulate synaptic transmissions in the central nervous system. Additionally, glia modulations showed antiallodynic and antihyperalgesic properties in various experimental pain models. Minocycline, a semisynthetic, second-generation tetracycline can potently inhibit microglial activation and proliferation. Also, the growing body of recent evidence indicates that minocycline attenuates morphine tolerance in neuropathic mice with a mechanism related to microglia. The combination of morphine and minocycline has synergetic effect. This can prevent the development of intractable PHN and attenuate morphine antinociceptive tolerance and further improve the efficacy of morphine and therefore reducing its dosage and side effects. We thereby hypothesize that the combination of morphine and minocycline may produce a duel effect of morphine antinociceptive and minocycline selectively inhibiting the activation of microglia. PMID

    This report presents the clinical results three months after application of minocycline microspheres as an adjunct to mechanical treatment of incipient peri-implant infections compared to adjunctive treatment employing 1% chlorhexidine gel application. Sixteen patients in the minocycline group and 14 in the chlorhexidine group completed the study. Each patient had one or more implants with probing depth > or = 4 mm combined with bleeding and/or exudate on probing and presence of putative pathogenic bacteria. At baseline, patients were randomly assigned to minocycline or chlorhexidine treatment. Follow-up examinations were carried out after 10, 30, 60 and 90 days. The combined mechanical/antimicrobial treatment for the chlorhexidine group did not result in any reduction in probing depth and only limited reduction of bleeding scores. The adjunctive use of minocycline microspheres, on the other hand, resulted in improvements in both probing depths and bleeding scores. For the deepest sites of the treated implants, mean probing depth was reduced from 5.0 mm to 4.1 mm. The reductions in bleeding scores, although greater than for the chlorhexidine group, were modest. Thus, the question as to what extent the combined mechanical/minocycline treatment could be considered adequate for the treated lesions remains to be answered. The present short-term findings, however, encourage further studies with longer observation intervals on adjunctive use of minocycline microspheres in the treatment of periimplant lesions.

    Minocycline is a tetracycline derivative mainly used in the treatment of acne vulgaris in young persons. Adverse events have been reported with minocycline, although it can be considered a safe drug. We report a case of severe hypersensitivity reaction to minocycline in a young patient. Laboratory examinations, chest X-ray, skin test and skin biopsy were performed. Oral challenge test with minocycline was not carried out as it can be hazardous. A case of severe reaction to minocycline is described in this article. The clinical and laboratory findings may be helpful in diagnosing similar reactions for which the immunological mechanisms are unknown. Moreover, this type of reaction must be recognized early due to the potential fatal outcome.

    Pigmentation secondary to minocycline ingestion is an uncommon adverse event affecting 3.7-14.8% of treated individuals for which few effective therapies are available. Three patterns of minocycline pigmentation have a characteristic clinical and histological appearance. The pigment composition in each variety is different and occurs at varying skin depths. Accordingly, a tailored approach according to the type of minocycline pigmentation is crucial for treatment success. The purpose of this intervention was to evaluate the efficacy of non-ablative fractional photothermolysis in combination with the Q-switched alexandrite laser for the treatment of type I minocycline pigmentation on the face. A patient with type I minocycline pigmentation was treated with non-ablative 1550-nm fractional photothermolysis followed immediately by 755-nm Q-switched alexandrite laser and then observed clinically to determine the outcome of this modality. The patient was seen in clinic 1 month later following her single treatment session and 100% clearance of all blue facial pigment was observed. Non-ablative fractional photothermolysis in combination with the 755-nm Q-switched alexandrite laser should be considered for treatment of type I minocycline pigmentation.

    Minocycline is the most widely prescribed systemic antibiotic for the management of acne. In the past several years, increasing attention has been paid to the drug, both for its potential use as a disease-modifying antirheumatic agent and for its propensity to engender untoward autoimmune reactions, including serum sickness-like disease, drug-induced lupus, and autoimmune hepatitis. This paper reviews the evidence for minocycline as an anti-inflammatory and immunomodulatory agent, its utility in the treatment of rheumatoid arthritis, and the spectrum of adverse reactions that have been ascribed to the drug in the past 5 years.

    Neonatal infection is associated with increased lifetime risk for neuropsychiatric disorders including anxiety and depression, with evidence showing that dysregulation of the hypothalamic-pituitary-adrenal-(HPA)-axis system may be partly responsible. Preclinical and clinical studies demonstrate that minocycline exhibits antidepressant effects through inhibition of microglial activation and anti-inflammatory actions, and of interest is that recent studies suggest that minocycline alleviates the behavioral abnormalities induced by early-life insults. The current study was designed to determine if developmental minocycline treatment attenuates the neonatal immune activation-induced anxiety- and depression-like symptoms and HPA-axis-dysregulation later in life. To this end, neonatal mice were treated to either lipopolysaccharide or saline on postnatal days (PND) 3-5, then dams during lactation (PND 6-20) and male offspring during adolescence (PND 21-40) received oral administration of minocycline or water via regular drinking bottles. Anxiety- and depression-like behaviors, HPA-axis-reactivity (corticosterone), and hippocampal inflammation (TNF-α and IL-1β) after exposure to stress were evaluated. The results indicated that neonatal immune activation resulted in increased anxiety and depression-like symptoms, HPA-axis-hyperactivity, and elevated the levels of TNF-α and IL-1β in the hippocampus in response to stress in adulthood. Interestingly, developmental minocycline treatment significantly reduced the abnormalities induced by neonatal inflammation in adult mice. In addition, minocycline, regardless of postnatal inflammation, did not have any detrimental effects on the above measured parameters. Considering that minocycline is currently under exploration as an alternative or adjunctive therapy for reducing the symptoms of neurological disorders, our findings suggest that minocycline during development can decrease the behavioral abnormalities induced by early

    Introduction The primary goal in periodontal therapy includes removal of the etiological factors by mechanical periodontal treatment, which sometimes fail to eliminate the anaerobic infection at the base of the pocket and requires adjuvant chemical therapy. Aim The aim of the study was to evaluate the effectiveness of 2% minocycline ointment when used as an adjunct to periodontal flap surgery and post-operative maintenance period for the treatment of generalized chronic periodontitis. Materials and Methods The study included 30 subjects comprising of 60 posterior sextants in a split mouth design in which 30 sextants were treated as experimental and 30 sextants as control with a probing pocket depth≥6mm. In Group A (experimental group) 30 sextants were treated with open flap debridement followed by the application of minocycline ointment as a local drug delivery. In Group B (control group) 30 sextants were treated with open flap debridement alone. Minocycline hydrochloride ointment was applied on the 0 day and 3rd month. The clinical parameters such as plaque index, probing pocket depth, clinical attachment level and gingival bleeding index were recorded at 0 day, 3rd month and 6th month in both the groups. Paired and unpaired t-test were used to compare the means of the two groups. Results When Group A and Group B were compared, Group A showed significantly greater reduction in gingival bleeding index, probing pocket depth and gain in clinical attachment level than Group B, from 0 day to 3 months and from 0 day to 6 months. Group A showed significant reduction in plaque index than Group B when they were compared at 6 months. Conclusion The results demonstrate that there was significant reduction in the clinical parameters with improvement in the periodontal status on application of minocycline ointment as an adjunct to periodontal flap surgery in generalized chronic periodontitis.

    The present study was conducted to investigate the effects of minocycline on the expression of selected transcriptional and translational profiles in the rat spinal cord following sciatic nerve (SNR) transection and microsurgical coaptation. The mRNA and protein expression levels of B cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein (Bax), caspase-3, major histocompatibility complex I (MHC I), tumor necrosis factor-α (TNF-α), activating transcription factor 3 (ATF3), vascular endothelial growth factor (VEGF), matrix metalloproteinase 9 (MMP9), and growth associated protein-43 (GAP-43) were monitored in the rat lumbar spinal cord following microsurgical reconstruction of the sciatic nerves and minocycline treatment. The present study used semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR) and immunohistochemistry. As a PCR analysis of spinal cord tissue enabled the examination of the expression patterns of all cell types including glia, the motorneuron-like NSC-34 cell line was used to investigate expression level changes in motorneurons. As stressors, oxygen glucose deprivation (OGD) and lipopolysaccharide (LPS) treatment were performed. SNR did not induce significant degeneration of ventral horn motorneurons, whereas microglia activation and synaptic terminal retraction were detectable. All genes were constitutively expressed at the mRNA and protein levels in untreated spinal cord and control cells. SNR significantly increased the mRNA expression levels of all genes, albeit only temporarily. In all genes except MMP9 and GAP-43, the induction was seen ipsilaterally and contralaterally. The effects of minocycline were moderate. The expression levels of MMP9, TNF-α, MHC I, VEGF, and GAP-43 were reduced, whereas those of Bax and Bcl-2 were unaffected. OGD, but not LPS, was toxic for NSC-34 cells. No changes in the expression levels of Bax, caspase-3, MHC I or ATF3 were observed. These results indicated that motorneurons were not

    The only treatment of patients with acute ischemic stroke is thrombolytic therapy, which benefits only a fraction of stroke patients. Both human and experimental studies indicate that ischemic stroke involves secondary inflammation that significantly contributes to the outcome after ischemic insult. Minocycline is a semisynthetic second-generation tetracycline that exerts antiinflammatory effects that are completely separate from its antimicrobial action. Because tetracycline treatment is clinically well tolerated, we investigated whether minocycline protects against focal brain ischemia with a wide therapeutic window. Using a rat model of transient middle cerebral artery occlusion, we show that daily treatment with minocycline reduces cortical infarction volume by 76 ± 22% when the treatment is started 12 h before ischemia and by 63 ± 35% when started even 4 h after the onset of ischemia. The treatment inhibits morphological activation of microglia in the area adjacent to the infarction, inhibits induction of IL-1β-converting enzyme, and reduces cyclooxygenase-2 expression and prostaglandin E2 production. Minocycline had no effect on astrogliosis or spreading depression, a wave of ionic transients thought to contribute to enlargement of cortical infarction. Treatment with minocycline may act directly on brain cells, because cultured primary neurons were also salvaged from glutamate toxicity. Minocycline may represent a prototype of an antiinflammatory compound that provides protection against ischemic stroke and has a clinically relevant therapeutic window. PMID:10557349

  15. Minocycline in acne vulgaris: benefits and risks.

    PubMed

    Ochsendorf, Falk

    2010-01-01

    Minocycline is a semi-synthetic, second-generation tetracycline. It was introduced in 1972 and has both antibacterial and anti-inflammatory properties. Minocycline is used for a variety of infectious diseases and in acne. Even today, new indications beyond the antibacterial indications are being investigated such as its use in neurologic diseases. Formerly, minocycline was thought to have a superior efficacy in the treatment of inflammatory acne, especially with respect to antibacterial-resistant Propionibacterium acnes. A thorough review of the literature, however, shows that minocycline is not more effective in acne than other tetracyclines. Compared with first-generation tetracyclines, minocycline has a better pharmacokinetic profile, and compared with doxycycline it is not phototoxic. However, minocycline has an increased risk of severe adverse effects compared with other tetracyclines. It may induce hypersensitivity reactions affecting the liver, lung, kidneys, or multiple organs (Drug Reaction with Eosinophilia and Systemic Symptoms [DRESS] syndrome) in the first weeks of treatment and, with long-term treatment, may cause autoimmune reactions (systemic lupus erythematosus, autoimmune hepatitis). In addition, CNS symptoms, such as dizziness, are more frequent compared with other tetracyclines. Long-term treatment may induce hyperpigmentation of the skin or other organs. Resistance of P. acnes to minocycline also occurs, dependent on the prescribing behavior. Considering the aspects of efficacy, its adverse effect profile, resistance, price, and alternatives, minocycline is no longer considered the first-line antibacterial in the treatment of acne.

    Minocycline is a semisynthetic tetracycline derivative that is often used in the treatment of acne vulgaris. To date, there has been only one case report of anaphylaxis to minocycline. We report here a case of anaphylaxis to oral minocycline. A 56-yr-old woman visited our hospital after three episodes of recurrent anaphylaxis. We performed an oral challenge test, the standard method for diagnosing drug allergies, with minocycline, one of the drugs she had taken previously. She developed urticaria, angioedema, nausea, vomiting, hypotension, and dyspnea within 4 min and was treated with intramuscular epinephrine, intravenous antihistamine and systemic corticosteroid. However, she presented similar symptoms at 50 min and at 110 min. In prescribing oral minocycline, physicians should consider the possibility of serious adverse reactions, such as anaphylaxis.

    Loss of intraepidermal nerve fibers (IENFs) has been speculated to play a critical role in the development of various neuropathies. In this study, the density of IENFs were studied over time during the induction of Taxol (Bristol-Myers Squibb, NY, USA)-induced chemoneuropathy and compared with the changes in IENFs in animals co-treated with Taxol plus the protective agent minocycline. Rats were injected (intraperitoneally) with 2mg/kg of Taxol every other day for four injections (day 1, 3, 5, and 7). Minocycline (25mg/kg) was given in a separate group of rats 24h prior to the first dose of Taxol and every day for the next 9days (day 0 through 9). Animals were tested for mechanical paw withdrawal thresholds prior to any drug administrations and again on day 7, 14, and 30. Immunohistochemistry using the pan-neuronal marker protein gene product 9.5 was performed on glabrous skin of the hind-paw foot pad to stain for IENFs also on day 7, 14, and 30. The results show that Taxol-treated animals developed mechanical sensitivity and corresponding IENF loss. Animals receiving minocycline plus Taxol showed no hyperalgesia or loss of IENFs. This study confirms, for the first time, that a loss of IENFs occurs as a neuropathy develops, and further shows a protection against both IENF loss and hyperalgesia with minocycline treatment. The progression of Taxol-induced mechanical hypersensitivity coincides with loss of intraepidermal nerve fibers, and the hyperalgesia and nerve fiber loss were prevented with minocycline treatment.

    We assessed the effects of minocycline, a tetracycline with anti-inflammatory, anti-apoptotic and neuroprotective capacities, in an animal model of post-traumatic stress disorder (PTSD). Rats were exposed to psychogenic stress and treated 1h later with minocycline or saline. Behavioral measures included the elevated plus-maze (EPM) and acoustic startle response (ASR) 7 days post stress-exposure. One day after behavioral testing, animals were exposed to a trauma cue and freezing response was assessed. Local levels of cytokines interleukin-1 (IL-1), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in the hippocampus, frontal cortex (FC) and hypothalamus were then examined. Minocycline attenuated anxious-like behaviors in stress-exposed rats. In addition, decreased levels of cytokines were measured in exposed rats treated with minocycline compared to their counterparts treated with saline. This study suggests a potential use of minocycline in preventing physiological and behavioral alternations resulting from acute exposure to psychological stress. As this is the first study to report beneficial outcomes for minocycline treatment in an animal model of PTSD, further investigations of the use of minocycline in stress-related conditions with emphasis on PTSD is needed.

One patient, aged 54 years, had taken minocycline due to lung silicosis for 3 years before black pigmentation of the face occurred. The other 49 year-old patient developed grey-black hyperpigmentation on both lower legs after a 6-month therapy with minocycline for folliculitis. This patient was treated with the Q-switched ruby laser and the pigmentation resolved in the treated area. The different clinical and histological forms of minocycline-induced hyperpigmentation are discussed.

    Although spinal glia acquire a reactive profile in radiculopathy, glial cell proliferation remains largely unstudied. This study investigated spinal glial proliferation in a model simulating painful disc herniation; the C7 nerve root underwent compression and chromic gut suture exposure or sham procedures. A subset of injured rats received minocycline injections prior to injury. Allodynia was assessed and bromodeoxyuridine (BrdU) was injected 2 hr before tissue harvest on day 1 or 3. Spinal cell proliferation and phenotype identification were assayed by fluorescent colabeling with antibodies to BrdU and either glial fibrillary acidic protein (astrocytes) or Iba1 (microglia). At day 1, ipsilateral allodynia was significantly increased (P < 0.001) for injury over sham. Minocycline treatment significantly decreased ipsilateral allodynia to sham levels at day 1 (P < 0.001). At day 3, ipsilateral allodynia remained and contralateral allodynia was also present for injury (P< 0.003) over sham. The number of BrdU-positive cells in the ipsilateral spinal dorsal horn at day 1 after injury was significantly elevated (P < 0.001) over sham. Approximately 70% of BrdU-positive cells labeled positively for Iba1; dividing microglia were significantly increased (P < 0.004) in the ipsilateral dorsal horn at day 1 following injury compared with sham. Spinal cellular proliferation after injury was not changed by minocycline injection. By day 3, the number of BrdU-positive cells had returned to sham levels bilaterally. Data indicate that spinal microglia proliferate after injury but that proliferation is not abolished by minocycline treatment that attenuates allodynia, indicating that spinal microglial proliferation may be related to injury and may not be linked to changes in sensory perception.

    Minocycline is a second-generation, semi-synthetic tetracycline that has been in therapeutic use for over 30 years because of its antibiotic properties against both gram-positive and gram-negative bacteria. It is mainly used in the treatment of acne vulgaris and some sexually transmitted diseases. Recently, it has been reported that tetracyclines can exert a variety of biological actions that are independent of their anti-microbial activity, including anti-inflammatory and anti-apoptotic activities, and inhibition of proteolysis, angiogenesis and tumour metastasis. These findings specifically concern to minocycline as it has recently been found to have multiple non-antibiotic biological effects that are beneficial in experimental models of various diseases with an inflammatory basis, including dermatitis, periodontitis, atherosclerosis and autoimmune disorders such as rheumatoid arthritis and inflammatory bowel disease. Of note, minocycline has also emerged as the most effective tetracycline derivative at providing neuroprotection. This effect has been confirmed in experimental models of ischaemia, traumatic brain injury and neuropathic pain, and of several neurodegenerative conditions including Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis, Alzheimer's disease, multiple sclerosis and spinal cord injury. Moreover, other pre-clinical studies have shown its ability to inhibit malignant cell growth and activation and replication of human immunodeficiency virus, and to prevent bone resorption. Considering the above-mentioned findings, this review will cover the most important topics in the pharmacology of minocycline to date, supporting its evaluation as a new therapeutic approach for many of the diseases described herein.

    We report two cases of drug-induced vasculitis subsequent to long-term minocycline therapy. Case 1; A 27-year-old woman, who was receiving minocycline hydrochloride for eosinophilic pustular folliculitis of 68-months'duration, showed polyarthralgia, intermittent low-grade fever, and light red reticulated erythemas with subcutaneous nodules on her extremities. Case 2; A 31-year-old man developed reddish-brown, reticulated erythemas with induration on bilateral lower legs after 24-months' duration of minocycline hydrochloride treatment for hidradenitis suppurativa. In both cases, skin biopsies demonstrated vasculitis affecting a small-sized artery at the border of the dermis and subcutis. Serum antineutrophil cytoplasmic antibodies (ANCA) showed borderline elevation. In both cases cessation of minocycline administration resulted in rapid improvement of cutaneous lesions and constitutional symptoms. Recently, attention has been focused on drug-induced ANCA-positive vasculitis. Accumulation of previous case reports of minocycline-induced vasculitis with cutaneous lesions disclosed that the duration of the treatment before clinical symptoms averaged 35 months. Patients may present with livedoid skin lesions accompanied by fever, polyarthritis, autoimmune hepatitis and drug-induced lupus. Early recognition of ANCA-positive vasculitis is essential during long-term minocycline treatment, because cessation of the drug can result in complete resolution.

    Elevated microglial/macrophage-associated biomarkers in the cerebrospinal fluid of infant victims of abusive head trauma (AHT) suggest that these cells play a role in the pathophysiology of the injury. In a model of AHT in 11-day-old rats, 3 impacts (24 hours apart) resulted in spatial learning and memory deficits and increased brain microglial/macrophage reactivity, traumatic axonal injury, neuronal degeneration, and cortical and white-matter atrophy. The antibiotic minocycline has been effective in decreasing injury-induced microglial/macrophage activation while simultaneously attenuating cellular and functional deficits in models of neonatal hypoxic ischemia, but the potential for this compound to rescue deficits after impact-based trauma to the immature brain remains unexplored. Acute minocycline administration in this model of AHT decreased microglial/macrophage reactivity in the corpus callosum of brain-injured animals at 3 days postinjury, but this effect was lost by 7 days postinjury. Additionally, minocycline treatment had no effect on traumatic axonal injury, neurodegeneration, tissue atrophy, or spatial learning deficits. Interestingly, minocycline-treated animals demonstrated exacerbated injury-induced spatial memory deficits. These results contrast with previous findings in other models of brain injury and suggest that minocycline is ineffective in reducing microglial/macrophage activation and ameliorating injury-induced deficits following repetitive neonatal traumatic brain injury.

    We report the case of a 19-year old black West Indian woman who had been treated for acne for two years with oral minocycline (50 mg per day) and topical of benzoyle peroxide (5%). She was admitted for fatigue, arthralgia, myalgia and widespread pruritus. We observed several skin lesions of hyperpigmentation, biological signs of hepatitis, and significant levels of antinuclear, anti-mitochondrial and anti-smooth muscle antibodies. Minocycline was immediately stopped. Two months later, all of the biological abnormalities had disappeared but the skin lesions seemed to be irreversible. Minocycline is largely used for the treatment of acne and may induce severe immuno-allergic reactions. Several cases of induced lupus, autoimmune hepatitis, eosinophilic pneumonia, hypersensitivity syndrome, serum-sickness-like illness and Sweet's syndrome have already been described. These side effects are rare but may be life-threatening. So, minocycline should be used as a second-line treatment for acne and should be avoided in black people whom seem to be at risk of such reactions. If, despite those precautions, minocycline-induced immuno-allergic reactions occur, the treatment should be immediately stopped and never prescribed again.

    Minocycline is an antibiotic widely used in the treatment of acne. Among the induced auto-immune disorders, cutaneous polyarteritis nodosa (PAN) is very rare. A new case is reported below. A 23-year-old female patient treated with minocycline for acne for 24 months developed sub-cutaneous nodules, livedo reticularis and pigmented lesions of the lower limbs. Antineutrophil cytoplasmic antibodies (ANCA) were positive at 1/320. Skin biopsy showed vasculitis of a medium-sized artery. The role of minocycline was suspected using the imputability criteria. The diagnosis of minocycline-induced cutaneous PAN with ANCA was sustained. After withdrawal of the treatment, the nodular lesions decreased spontaneously, whereas livedo disappeared and inflammatory parameters were normalized after oral corticosteroid therapy. Minocycline is a tetracycline which is efficient for treating acne. Auto-immune disorders are frequently observed. Among them, it is very rare to observe cutaneous PAN associated with positive ANCA. The pathophysiological mechanisms are discussed.

    We report four cases of the side effects of minocycline seen during the last two years in our department. There was one case of drug-related lupus and three cases of hypersensitivity reactions, including one eosinophilic pneumopathy with pericarditis, one nephropathy and one severe, pseudo-infectious episode of high fever, rash, lympadenopathy, hepatitis and eosinophilia. Minocycline is a tetracycline agent widely used for acne therapy in France and all over the world. During the last few years, there has been an increasing number of reports concerning systemic adverse reactions to minocycline, with on the one hand auto-immune disorders (lupus, autoimmune hepatitis, vascularitis with ANCA), occurring after a prolonged course of therapy and reported recently in the last few years, and on the other hand, hypersensitivity reactions (eosinophilic pneumopathies, hepatitis, nephropathies, myocarditis, serum sickness or pseudo-infectious reactions), occurring precociously in the course of therapy, and potentially severe. Although these side effects are uncommon in the context of the high number of patients who have been prescribed the drug, the first-line antibiotic therapy in acne must probably be reconsidered.

    Eighty percent of all cases of acute pancreatitis are linked etiologically to gallstone disease or caused by immoderate alcohol consumption. No specific causal treatment for acute pancreatitis exists. Early prognostic factors that indicate severe disease are three or more signs on organ failure scores according to Ranson, Imrie, or Acute Physiology and Chronic Health Evaluation (APACHE) 11, extrapancreatic complications of the disease, or the detection of pancreatic necrosis on CT scans. Elevated CRP levels above 130 mg/L can also predict a severe course of acute pancreatitis. The essential medical treatment for acute pancreatitis is the correction of hypovolemia. Moreover, relief of often severe visceral pain is a high priority. Prophylactic antibiotics should be restricted to patients with necrotizing pancreatitis, infected necrosis, or other infectious complications. Enteral nutrition has no adverse effect compared with parenteral nutrition during the course of acute pancreatitis, and is probably beneficial in regard to outcome.

    A recent publication of the results of a clinical trial of minocycline in 412 ALS patient has aroused considerable controversy in the ALS scientific community. As on previous occasions, the results obtained in the laboratory are not reproduced in clinical practice. The reasons for this new disappointment in translational medicine are analysed by applying the successes obtained in the experimental animal model for ALS to humans. The most frequently suggested causes for explaining these continuous failures are unawareness of the correct dosage to be used, the ideal duration of the clinical trial in phase III, sample size, the search for a primary outcome for measurement other than survival, the need for biomarkers giving information on the progression of the disease and whether this is modified by the introduction of the drug for study. Debate focuses on whether the transgenic mouse model of ALS which expresses SOD1 mutations which we have been using for more than a decade is an exact reflection of the clinical profile and the physiopathogenic mechanisms present in patients with spo- radic ALS. There is the possibility that depending on the dose administered, minocycline can be a neuroprotector or a neurotoxin. In other words, at a dose of 200 mg/day, this drug behaves like and like at doses of 400 mg. For the authors of the trial, this possibility does not seem to be the cause of the disappointing results obtained. However, they acknowledge that one of the limitations of their study was that it was impossible to compare the effects of minocycline in the patient after receiving 200 or 400 mg. For many other researchers running ongoing clinical trials in both ALS and other neurological diseases, the dose of 200 mg/day is chosen as ideal for testing the effectiveness of minocycline in patients. The strategy of administering the maximum dose of a drug to be tested may give rise to misleading results. We agree with the opinion of other authors

  11. Analysis of Minocycline as a Radioprotectant

    NASA Astrophysics Data System (ADS)

    Exposure to radiation is increasing in a variety of settings including space exploration, diagnostic medical procedures and radiotherapy. Cells of the hematopoietic system, such as white blood cells (WBC), are especially sensitive to radiation and their decline can result in Acute Radiation Syndrome (ARS). Radiotherapy is often used for cancers of the central nervous system (CNS), but includes the risk for normal tissue damage, often leading to cognitive impairment. The literature suggests that tetracyclines can be radioprotectors of the hematopoietic system with potential utility in radiation emergencies and anticancer radiotherapy. Minocycline, a semisynthetic tetracycline derivative, has anti-inflammatory, free radical scavenging, anti-apoptotic and anti-angiogenic properties with exceptional penetration into the CNS. These qualities make it a viable candidate for use in combination with radiotherapy for CNS tumors as a normal tissue radioprotectant and for hematopoietoc recovery following whole-body irradiation. This study was undertaken to determine the potential of minocycline as a radioprotective agent of the hematopoietic system and CNS in response to whole-body irradiation with 1, 2 and 3 Gy (γ-rays). C57BL/6 mice were injected with minocycline, 5 times beginning immediately before irradiation. Spleen, blood and brain were collected on days 4 and 32 post-irradiation. WBC and other cell populations were determined in the blood and spleen while cytokines were quantified in CD3-activated splenocytes and homogenized brain supernatants. We also evaluated the impact of minocycline on DNA synthesis and viability of human glioblastoma cells versus astrocytes and microglia. Minocycline increased counts and percentages of splenic macrophages, granulocytes, natural killer (NK), T and CD8 + T cells on day 4 and B cells on day 32. Minocycline up-regulated interleukin-1α (IL-1α)which is radioprotective, as well as

    While current pharmacotherapies are efficacious, there remain a clear shortfall between symptom remission and functional recovery. With the explosion in our understanding of the biology of these disorders, the time is ripe for the investigation of novel therapies. Recently depression is conceptualized as an immune-inflammatory and nitro-oxidative stress related disorder. Minocycline is a tetracycline antibiotic that has anti-inflammatory, pro-oxidant, glutamatergic, neurotrophic and neuroprotective properties that make it a viable target to explore as a new therapy. This double blind, randomised, placebo controlled adjunctive trial will investigate the benefits of 200 mg/day of minocycline treatment, in addition to any usual treatment, as an adjunctive treatment for moderate-severe major depressive disorder. Sixty adults are being randomised to 12 weeks of treatment (with a 4 week follow-up post-discontinuation). The primary outcome measure for the study is mean change on the Montgomery-Asberg Depression Rating Scale (MADRS), with secondary outcomes including the Social and Occupational Functioning Assessment Scale (SOFAS), Clinical Global Impressions (CGI), Hamilton Rating Scale for Anxiety (HAM-A), Patient Global Impression (PGI), Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q) and Range of Impaired Functioning Tool (LIFE-RIFT). Biomarker analyses will also be conducted at baseline and week 12. The study has the potential to provide new treatment targets, both by showing efficacy with a new class of 'antidepressant' but also through the analysis of biomarkers that may further inform our understanding of the pathophysiology of unipolar depression.

    This animal study was designed to determine if minocycline ameliorates cochlear damage is caused by intratympanic injection of the ototoxic aminoglycoside antibiotic neomycin. Baseline auditory-evoked brainstem responses were measured in gerbils that received 40 mM intratympanic neomycin either with 0, 1.2, or 1.5 mg/kg intraperitoneal minocycline. Four weeks later auditory-evoked brainstem responses were measured and compared to the baseline measurements. Minocycline treatments of 1.2 mg/kg and 1.5 mg/kg resulted in significantly lower threshold increases compared to 0 mg/kg, indicating protection of hearing loss between 6 kHz and 19 kHz. Cochleae were processed for histology and sectioned to allow quantification of the spiral ganglion neurons and histological evaluation of organ of Corti. Significant reduction of spiral ganglion neuron density was demonstrated in animals that did not receive minocycline, indicating that those receiving minocycline demonstrated enhanced survival of spiral ganglion neurons, enhanced survival of sensory hairs cells and spiral ganglion neurons, and reduced hearing threshold elevation correlates with minocycline treatment demonstrating that neomycin induced hearing loss can be reduced by the simultaneous application of minocycline.

    Dengue virus infection is one of the most common arthropod-borne viral diseases. A complex interplay between host and viral factors contributes to the severity of infection. The antiviral effects of three antibiotics, lomefloxacin, netilmicin, and minocycline, were examined in this study, and minocycline was found to be a promising drug. This antiviral effect was confirmed in all four serotypes of the virus. The effects of minocycline at various stages of the viral life cycle, such as during viral RNA synthesis, intracellular envelope protein expression, and the production of infectious virions, were examined and found to be significantly reduced by minocycline treatment. Minocycline also modulated host factors, including the phosphorylation of extracellular signal-regulated kinase1/2 (ERK1/2). The transcription of antiviral genes, including 2'-5'-oligoadenylate synthetase 1 (OAS1), 2'-5'-oligoadenylate synthetase 3 (OAS3), and interferon α (IFNA), was upregulated by minocycline treatment. Therefore, the antiviral activity of minocycline may have a potential clinical use against Dengue virus infection. PMID:27396621

    There are many options for acute migraine attack treatment, but none is ideal for all patients. This study aims to review current medical office-based acute migraine therapy in adults and provides readers with an organized approach to this important facet of migraine treatment. A general literature review includes a review of several recent published guidelines. Acetaminophen, 4 nonsteroidal anti-inflammatory drugs (NSAIDs) (ibuprofen, acetylsalicylic acid [ASA], naproxen sodium, and diclofenac potassium), and 7 triptans (almotriptan, eletriptan, frovatriptan, naratriptan, rizatriptan, sumatriptan, and zolmitriptan) have good evidence for efficacy and form the core of acute migraine treatment. NSAID-triptan combinations, dihydroergotamine, non-opioid combination analgesics (acetaminophen, ASA, and caffeine), and several anti-emetics (metoclopramide, domperidone, and prochlorperazine) are additional evidence-based options. Opioid containing combination analgesics may be helpful in specific patients, but should not be used routinely. Clinical features to be considered when choosing an acute migraine medication include usual headache intensity, usual rapidity of pain intensity increase, nausea, vomiting, degree of disability, patient response to previously used medications, history of headache recurrence with previous attacks, and the presence of contraindications to specific acute medications. Available acute medications can be organized into 4 treatment strategies, including a strategy for attacks of mild to moderate severity (strategy one: acetaminophen and/or NSAIDs), a triptan strategy for patients with severe attacks and for attacks not responding to strategy one, a refractory attack strategy, and a strategy for patients with contraindications to vasoconstricting drugs. Acute treatment of migraine attacks during pregnancy, lactation, and for patients with chronic migraine is also discussed. In chronic migraine, it is particularly important that medication

    Objective Clozapine is the most effective antipsychotic for treatment refractory people with schizophrenia, yet many patients only partially respond. Accumulating preclinical and clinical data suggest benefits with minocycline. We tested adjunct minocycline to clozapine in a 10 week, double blind placebo-controlled trial. Primary outcomes tested were positive and cognitive symptoms, while avolition, anxiety/depression and negative symptoms were secondary outcomes. Methods Schizophrenia and schizoaffective participants (N=52) with persistent positive symptoms were randomized to receive adjunct minocycline (100 mg oral capsule twice daily) (N=29) or placebo (N=23). Results Brief Psychiatric Rating Scale (BPRS) psychosis factor (p=0.098, effect size ES=0.39) and BPRS total score (p=0.075, effect size 0.55) were not significant. A ≥30% change in total BPRS symptoms was observed in 7/28 (25%) among minocycline and 1/23 (4%) among placebo participants, respectively (p=0.044). Global cognitive function (MATRICS Consensus Cognitive Battery, MCCB) did not differ, although there was a significant variation in size of treatment effects among cognitive domains (p=0.03), with significant improvement in working memory favoring minocycline (p=0.023, ES 0.41). The SANS total score did not differ, but significant improvement in avolition with minocycline was noted (p=0.012, ES=0.34). Significant improvement in the BPRS anxiety/depression factor was observed with minocycline (p=0.028, ES=0.49). Minocycline was well tolerated with significantly fewer headaches and constipation compared to placebo. Conclusion Minocycline’s effect on the MCCB composite score and positive symptoms were not statistically significant. Significant improvements with minocycline were seen in working memory, avolition and anxiety/depressive symptoms in a chronic population with persistent symptoms. Larger studies are needed to validate these findings. PMID:26082974

    Minocycline, prescribed for a patient with acne, produced a photosensitivity reaction (photo-onycholysis) involving the fingernails. The onset of this reaction coincided with an increase in sun exposure and cleared several months later, when the drug was discontinued. This type of reaction has been reported to occur in patients taking tetracycline or a member of the tetracycline group of antibiotics, of which minocycline is a member. This appears to be first report of photo-onycholysis due to minocycline.

    Optimum acute treatment of migraine requires prevention of headache as a top priority. Recognition of the multitude of migraine presentations, the frequency of total headache attacks, and number of days of headache disability are critical. Successful treatment requires excellent patient-clinician communication enhancing confidence and mutual trust based on patient needs and preferences. Optimum management of acute migraine nearly always requires pharmacologic treatment for rapid resolution. Migraine-specific triptans, dihydroergotamine, and several antiinflammatories have substantial empirical clinical efficacy. Older nonspecific drugs, particularly butalbital and opioids, contribute to medication overuse headache and are to be avoided. Clinicians should utilize evidence-based acute migraine-specific therapy stressing the imperative acute treatment goal of early intervention, but not too often with the correct drug, formulation, and dose. This therapy needs to provide cost-effective fast results, meaningful to the patient while minimizing the need for additional drugs. Migraine-ACT evaluates 2-hour pain freedom with return to normal function, comfort with treatment, and consistency of response. Employ a thoroughly educated patient, formulary, testimonials, stratification, and rational cotherapy against the race to central sensitization for optimum outcomes. PMID:20352584

    The effects of minocycline on behavioral changes and neurotoxicity in the dopaminergic neurons induced by the administration of methamphetamine (METH) were studied. Pretreatment with minocycline (40 mg/kg) was found to attenuate hyperlocomotion in mice after a single administration of METH (3 mg/kg). The development of behavioral sensitization after repeated administration of METH (3 mg/kg/day, once daily for 5 days) was significantly attenuated by pretreatment with minocycline (40 mg/kg). A reduction in the level of dopamine (DA) and its major metabolite, 3,4-dihydroxyphenyl acetic acid (DOPAC), in the striatum after the repeated administration of METH (3 mg/kg x 3, 3-h interval) was attenuated in a dose-dependent manner by pretreatment with and the subsequent administration of minocycline (10, 20, or 40 mg/kg). Furthermore, minocycline (40 mg/kg) significantly attenuated a reduction in DA transporter (DAT)-immunoreactivity in the striatum after repeated administration of METH. In vivo microdialysis study demonstrated that pretreatment with minocycline (40 mg/kg) significantly attenuated increased extracellular DA levels in the striatum after the administration of METH (3 mg/kg). In addition, minocycline was not found to alter the concentrations of METH in the plasma or the brain after three injections of METH (3 mg/kg), suggesting that minocycline does not alter the pharmacokinetics of METH in mice. Interestingly, METH-induced neurotoxicity in the striatum was significantly attenuated by the post-treatment and subsequent administration of minocycline (40 mg/kg). These findings suggest that minocycline may be able to ameliorate behavioral changes as well as neurotoxicity in dopaminergic terminals after the administration of METH. Therefore, minocycline could be considered as a useful drug for the treatment of several symptoms associated with METH abuse in humans.

    Objective To report an 18-month follow-up on creatine and minocycline futility study, the Neuroprotective Exploratory Trials in Parkinson Disease, Futility Study 1 (NET-PD FS-1). Background The NET-PD FS-1 futility study on creatine and minocycline found neither agent futile in slowing down the progression of disability in Parkinson disease (PD) at 12 months using the prespecified futility threshold. An additional 6 months of follow-up aimed to assess safety and potential interactions of the study interventions with anti-parkinsonian therapy. Methods Additional 6 months of follow-up in randomized, blinded phase II trial of creatine (dosage, 10 g/d) and minocycline (dosage, 200 mg/d) in subjects with early PD. Results By 18 months, symptomatic treatment of PD symptoms was required in 61% of creatine, 62% of minocycline, and 60% of placebo-treated subjects. Study treatment was prematurely discontinued in 9%, 23%, and 6% of subjects in the creatine, minocycline, and placebo arms, respectively. Creatine and minocycline did not seem to adversely influence the response to symptomatic therapy nor increase adverse events. Conclusions Data from this small, 18-month phase II trial of creatine and minocycline do not demonstrate safety concerns that would preclude a large, phase III efficacy trial, although the decreased tolerability of minocycline is a concern.

    The effects of minocycline on the development of diabetic nephropathy (DN) in streptozotocin (STZ) induced diabetic rats were evaluated in this study. The diabetes rats with DN were induced by STZ (55 mg/kg) injection. The experiment included 5 groups 1) normal, 2) normal plus minocycline for 16 weeks, 3) DN plus vehicle, 4) DN plus minocycline 16 weeks and 5) DN plus minocycline for 8 weeks. The pathological changes were analyzed by hematoxylin and eosin (H&E) staining and the apoptotic cells were stained by terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick-end labeling (TUNEL) staining. The mRNA expression of caspase-3, Bax and Bcl-2 in the kidney tissues was detected by quantitative RT-PCR. The biochemical parameters of blood and urine were determined by biochemical analyzer. Treatment with minocycline reduced the urine volume, 24-h urine protein, serum creatinine (Scr), blood urea nitrogen (BUN) but not blood alanine aminotransferase (ALT) in the DN rats. Furthermore, treatment with minocycline improved the pathological score of STZ-injured kidney and reduced the numbers of apoptotic cells in the kidney of DN rats. Moreover, minocycline mitigated the expression of caspase-3 and Bax mRNA, but increased Bcl-2 expression in the kidney of DN rats. These data indicated that minocycline improved the STZ-induced kidney damages, at least partially by protection form long-term hyperglycemia-induced kidney cell apoptosis. PMID:27476934

    Fragile X syndrome (FXS) is the most common known genetic form of intellectual disability and autism spectrum disorders. FXS patients suffer a broad range of other neurological symptoms, including hyperactivity, disrupted circadian activity cycles, obsessive-compulsive behavior, and childhood seizures. The high incidence and devastating effects of this disease state make finding effective pharmacological treatments imperative. Recently, reports in both mouse and Drosophila FXS disease models have indicated that the tetracycline derivative minocycline may hold great therapeutic promise for FXS patients. Both models strongly suggest that minocycline acts on the FXS disease state via inhibition of matrix metalloproteinases (MMPs), a class of zinc-dependent extracellular proteases important in tissue remodeling and cell-cell signaling. Recent FXS clinical trials indicate that minocycline may be effective in treating human patients. In this paper, we summarize the recent studies in Drosophila and mouse FXS disease models and human FXS patients, which indicate that minocycline may be an effective FXS therapeutic treatment, and discuss the data forming the basis for the proposed minocycline mechanism of action as an MMP inhibitor.

    Fragile X Syndrome (FXS) is the most common single-gene inherited form of intellectual disability with behaviors characteristic of autism. People with FXS display childhood seizures, hyperactivity, anxiety, developmental delay, attention deficits, and visual-spatial memory impairment, as well as a propensity for obsessive-compulsive disorder. Several of these aberrant behaviors and FXS-associated synaptic irregularities also occur in "fragile X mental retardation gene" knock-out (Fmr1 KO) mice. We previously reported that minocycline promotes the maturation of dendritic spines - postsynaptic sites for excitatory synapses - in the developing hippocampus of Fmr1 KO mice, which may underlie the beneficial effects of minocycline on anxiolytic behavior in young Fmr1 KO mice. In this study, we compared the effectiveness of minocycline treatment in young and adult Fmr1 KO mice, and determined the dependence of behavioral improvements on short-term versus long-term minocycline administration. We found that 4- and 8-week-long treatments significantly reduced locomotor activity in both young and adult Fmr1 KO mice. Some behavioral improvements persisted in young mice post-treatment, but in adults the beneficial effects were lost soon after minocycline treatment was stopped. We also show, for the first time, that minocycline treatment partially attenuates the number and severity of audiogenic seizures in Fmr1 KO mice. This report provides further evidence that minocycline treatment has immediate and long-lasting benefits on FXS-associated behaviors in the Fmr1 KO mouse model.

    Brain/machine interfaces could potentially be used in the treatment of a host of neurological disorders ranging from paralysis to sensory deficits. Insertion of chronic micro-electrode arrays into neural tissue initiates a host of immunological responses, which typically leads to the formation of a cellular sheath around the implant, resulting in the loss of useful signals. Minocycline has been shown to have neuroprotective and neurorestorative effects in certain neural injury and neurodegenerative disease models. This study examined the effects of minocycline administration on the quality and longevity of chronic multi-channel microwire neural implants 1 week and 1 month post-implantation in auditory cortex. The mean signal-to-noise ratio for the minocycline group stabilized at the end of week 1 and remained above 4.6 throughout the following 3 weeks. The control group signal-to-noise ratio dropped throughout the duration of the study and at the end of 4 weeks was 2.6. Furthermore, 68% of electrodes from the minocycline group showed significant stimulus-driven activity at week 4 compared to 12.5% of electrodes in the control group. There was a significant reduction in the number of activated astrocytes around the implant in minocycline subjects, as well as a reduction in total area occupied by activated astrocytes at 1 and 4 weeks.

    Acute radiation dermatitis is a common side-effect of radiotherapy which often necessitates interruption of the therapy. Currently, there is no general consensus about its prevention or about the treatment of choice. The goal of this work was to focus on optimal methods to prevent and manage acute skin reactions related to radiation therapy and to determine if there are specific topical or oral agents for the prevention of this acute skin reaction.

    The tetracycline antibiotic minocycline can exert strong anti-inflammatory, antioxidant, and antiapoptotic effects. There is cumulating evidence that epileptogenic brain insults trigger neuroinflammation and anti-inflammatory concepts can modulate the process of epileptogenesis. Based on the mechanisms of action discussed for minocycline, the compound is of interest for intervention studies as it can prevent the polarization of microglia into a pro-inflammatory state. Here, we assessed the efficacy of sub-chronic minocycline administration initiated immediately following an electrically-induced status epilepticus in rats. The treatment did not affect the development of spontaneous seizures. However, minocycline attenuated behavioral long-term consequences of status epilepticus with a reduction in hyperactivity and hyperlocomotion. Furthermore, the compound limited the spatial learning deficits observed in the post-status epilepticus model. The typical status epilepticus-induced neuronal cell loss was evident in the hippocampus and the piriform cortex. Minocycline exposure selectively protected neurons in the piriform cortex and the hilus, but not in the hippocampal pyramidal layer. In conclusion, the data argue against an antiepileptogenic effect of minocycline in adult rats. However, the findings suggest a disease-modifying impact of the tetracycline affecting the development of behavioral co-morbidities, as well as long-term consequences on spatial learning. In addition, minocycline administration resulted in a selective neuroprotective effect. Although strong anti-inflammatory effects have been proposed for minocycline, we could not verify these effects in our experimental model. Considering the multitude of mechanisms claimed to contribute to minocycline's effects, it is of interest to further explore the exact mechanisms underlying the beneficial effects in future studies.

    Minocycline has been reported to reduce infarct size after focal cerebral ischemia, due to an attenuation of microglia activation and prevention of secondary damage from stroke-induced neuroinflammation. We here investigated the effects of minocycline on endogenous neural stem cells (NSCs) in vitro and in a rat stroke model. Primary cultures of fetal rat NSCs were exposed to minocycline to characterize its effects on cell survival and proliferation. To assess these effects in vivo, permanent cerebral ischemia was induced in adult rats, treated systemically with minocycline or placebo. Imaging 7 days after ischemia comprised (i) Magnetic Resonance Imaging (MRI), assessing the extent of infarcts, (ii) Positron Emission Tomography (PET) with [(11)C]PK11195, characterizing neuroinflammation, and (iii) PET with 3'-deoxy-3'-[(18)F]fluoro-L-thymidine ([(18)F]FLT), detecting proliferating endogenous NSCs. Immunohistochemistry was used to verify ischemic damage and characterize cellular inflammatory and repair processes in more detail. In vitro, specific concentrations of minocycline significantly increased NSC numbers without increasing their proliferation, indicating a positive effect of minocycline on NSC survival. In vivo, endogenous NSC activation in the subventricular zone (SVZ) measured by [(18)F]FLT PET correlated well with infarct volumes. Similar to in vitro findings, minocycline led to a specific increase in endogenous NSC activity in both the SVZ as well as the hippocampus. [(11)C]PK11195 PET detected neuroinflammation in the infarct core as well as in peri-infarct regions, with both its extent and location independent of the infarct size. The data did not reveal an effect of minocycline on stroke-induced neuroinflammation. We show that multimodal PET imaging can be used to characterize and quantify complex cellular processes occurring after stroke, as well as their modulation by therapeutic agents. We found minocycline, previously implied in attenuating

    Previous studies have suggested that minocycline can attenuate cognitive deficits in animal models of conditions such as Alzheimer's disease and cerebral ischemia through inhibiting microglia associated anti-inflammatory actions. However the pathway that minocycline targets to enhance cognitive performance is not fully defined. Here we examined the effects of minocycline on learning and memory in aged (22-month-old) C57 BL/6 mice. We treated one group of mice with minocycline (30 mg/kg/day), and another group of mice with donepezil (2 mg/kg/day) as a positive control. The Morris water maze and passive avoidance tests were used to evaluate the effects of minocycline on learning and memory deficits. We also used high-frequency stimulation-induced long-term potentiation and Golgi-Cox staining to assess the effect of minocycline on synaptic plasticity and synaptogenesis. The effects of minocycline on synapse-associated signaling proteins were determined by western blot. We found that minocycline ameliorates cognitive deficits, enhances neuroplasticity, activates brain-derived neurotrophic factor- extracellular signal-regulated kinases signaling and increases expression of Arc, EGR1 and PSD-95 in the CA1 and dentate gyrus regions of the hippocampus in aged mice. The effects of minocycline in aged mice were similar to those of donepezil. Our results suggest that minocycline could improve learning and memory through enhancing synaptic plasticity and synaptogenesis, modulating the expression of synapse-associated signaling proteins, which provide a rationale for exploring the viability of using minocycline treatment in cognitive deficits.

    Tetracyclines exhibit significant anti-inflammatory properties in a variety of rheumatologic and dermatologic conditions. They have also been shown to inhibit apoptosis in certain neurodegenerative disorders. Because ischemic renal injury is characterized by both apoptosis and inflammation, we investigated the therapeutic potential of tetracyclines in a rat model of renal ischemia-reperfusion. Male Sprague-Dawley rats underwent bilateral renal artery clamp for 30 min followed by reperfusion and received either minocycline or saline for 36 h before ischemia. Minocycline reduced tubular cell apoptosis 24 h after ischemia as determined by terminal transferase-mediated dUTP nick end-labeling staining and nuclear morphology. It also decreased cytochrome c release into the cytoplasm and reduced upregulation of p53 and Bax after ischemia. The minocycline-treated group showed a significant reduction in tubular injury and cast formation. In addition, minocycline reduced the number of infiltrating leukocytes, decreased leukocyte chemotaxis both in vitro and ex vivo, and downregulated the expression of ICAM-1. Serum creatinine 24-h postischemia was significantly reduced in the minocycline-treated group. We conclude that minocycline has potent antiapoptotic and anti-inflammatory properties and protects renal function in this model of ischemia-reperfusion. Tetracyclines are among the safest and best-studied antibiotics. They are thus attractive candidates for the therapy of human ischemic acute renal failure. PMID:15172883

    Recurrent acute pancreatitis (RAP) is a challenging condition that can lead to chronic pancreatitis and long-term morbidity. Etiology-based treatment can potentially have an impact on the natural history of RAP and its progression to chronic pancreatitis. In cases of divisum-associated RAP and idiopathic RAP, several studies have been performed to evaluate the efficacy of endoscopic therapy in alleviation of symptoms and frequency of AP events. This review discusses the literature available on these topic as well as touching on the role of endoscopic therapy in smoldering acute pancreatitis.

    Erythema nodosum leprosum is defined by the appearance of tender skin nodules, which can be accompanied by fever, joint pain, neuritis, edema, malaise and/or lymphadenopathy. The authors describe the case of a 19-year-old Angolan black woman, resident in Portugal for the last 10 years, diagnosed with Hansen's disease at the age of 12, irregular with follow-up and non-compliant with treatment. She was referred to our clinic with painful nodules and pustules on the upper limbs, diffuse facial infiltration with pustules and fever, after initiating minocycline with the intention of treating acne. Diagnosis of erythema nodosum leprosum was confirmed by the presence of acid-fast bacilli in the skin smear and also in skin biopsy. Minocycline was suspended and the patient was treated with systemic steroids, with prompt clinical improvement. Our case is reported to alert clinicians to this unusual presentation of erythema nodosum leprosum in a patient treated with highly bactericidal drugs that were not intended to treat Hansen's disease.

    Minocycline is a tetracycline derivative antibiotic commonly prescribed for acne, rosacea, and other inflammatory skin disorders. Minocycline turns black when oxidized, leading to discoloration of the skin, nails, bulbar conjunctiva, oral mucosa, teeth, bones, and thyroid gland. Hyperpigmentation has been reported after long-term minocycline therapy with at least 100 mg/day. Three types of minocycline-induced cutaneous hyperpigmentation can result. Type I is the most common, and is associated with blue-black discoloration in areas of previous inflammation and scarring. Type II most commonly affects the legs and is characterized by blue-gray pigmentation of previously normal skin. Type III is the least common and is characterized by diffuse muddy-brown discoloration predominantly on sun exposed skin. Minocycline-induced hyperpigmentation may be cosmetically disfiguring and prompt identification is essential. Without treatment, symptoms may take several months, to years to resolve, after discontinuation of the drug. However, the pigmentation may never completely disappear. In fact, there have been few reports of complete resolution associated with any therapeutic intervention. We report a case of a patient on long-term minocycline therapy utilized as an anti-inflammatory agent to control symptoms of rheumatoid arthritis, which led to minocycline-induced hyperpigmentation of the face. To remove the blue-gray cutaneous deposits, 3 Q-switched lasers (Neodymium: yttrium aluminum garnet (Nd:YAG) 1064 nm, Alexandrite 755 nm, and Ruby 694 nm) were used in test areas. The Alexandrite 755 nm laser proved to provide effective clearing of the minocycline hyperpigmentation requiring just 2 treatments, with minimal treatment discomfort and down time. PMID:23754872

    The association of vitamin C deficiency with nutritional factors is commonly recognized. However, an acute form of scurvy can occur in patients with an acute systemic inflammatory response, which is produced by sepsis, medications, cancer or acute inflammation. The frequency of acute hypovitaminosis C in hospitalized patients is higher than previously recognized. We report the occurrence of acute signs and symptoms of scurvy (perifollicular petechiae, erythema, gingivitis and bleeding) in a patient hospitalized for treatment of metastatic renal-cell carcinoma with high-dose interleukin-2. Concomitantly, serum vitamin C levels decreased to below normal. Better diets and longer lifespan may result a lower frequency of acute scurvy and a higher frequency of scurvy associated with systemic inflammatory responses. Therefore, increased awareness of this condition can lead to early recognition of the cutaneous signs of acute scurvy in hospitalized patients with acute illnesses or in receipt of biological agents, and prevent subsequent morbidity such as bleeding, anaemia, impaired immune defences, oedema or neurological symptoms.

    In the present study we compared the effects of minocycline and ascorbic acid in the life span, motor activity and lipid peroxidation of Drosophila melanogaster, in an effort to find a substance capable of providing protection against oxidative stress in aging. In the flies treated with minocycline a very significant increase in the life span (101 +/- 1.33 days) was observed when compared to those treated with ascorbic acid and controls (42.3% and 38.4%, respectively). The motor activity of minocycline treated flies also increased significantly with respect to control and ascorbic acid fed flies, from the 3rd to the 9th week of treatment. With regard to lipid peroxidation, it was found that the levels of malondialdehyde (MDA) in flies treated with minocycline showed no statistical differences to the control on the first day of treatment, but a significantly lower content on the day of 50% survival. In contrast, in flies treated with ascorbic acid significantly elevated levels of MDA compared to control and minocycline treated flies were detected throughout. These results suggest a protective effect of minocycline against oxidative stress and aging in D. melanogaster. An inhibitory effect on reactive oxygen species production may be an important contributing factor.

    Excessive hyperbilirubinemia in human neonates can cause permanent dysfunction of the auditory system, as assessed with brainstem auditory evoked potentials (BAEPs). Jaundiced Gunn rat pups (jjs) exhibit similar BAEP abnormalities as hyperbilirubinemic neonates. Sulfadimethoxine (sulfa) administration to jjs, which displaces bilirubin from serum albumin into tissues including brain, exacerbates acute toxicity. Minocycline administered prior to sulfa in jjs protects against BAEP abnormalities. This study evaluates the neuroprotective capabilities of minocycline HCl (50 mg/kg) administered 30 or 120 min after sulfa (200 mg/kg) in 16 days old jjs. BAEPs are recorded at 6 or 24 h post-sulfa. Abnormal BAEP waves exhibit increased latency and decreased amplitude. The sulfa/saline treated jjs exhibited a significantly increased interwave interval between waves I and II (I-II IWI) and significantly decreased amplitudes of waves II and III compared to the saline/saline jjs. The minocycline 30 min post-sulfa (sulfa/mino+30) group was not significantly different from the saline/saline control group, indicating neuroprotection. The minocycline 120 min post-sulfa (sulfa/mino+120) group had a significantly decreased amplitude of wave III at both 6 and 24h. These studies indicate that minocycline has a graded neuroprotective effect when administered after acute bilirubin neurotoxicity.

    Hemorrhagic transformation is an important complication of acute ischemic stroke, particularly in diabetic patients receiving thrombolytic treatment with tissue plasminogen activator, the only approved drug for the treatment of acute ischemic stroke. The objective of the present study was to determine the effects of acute manipulation of potential targets for vascular protection [i.e., NF-κB, peroxynitrite, and matrix metalloproteinases (MMPs)] on vascular injury and functional outcome in a diabetic model of cerebral ischemia. Ischemia was induced by middle cerebral artery occlusion in control and type 2 diabetic Goto-Kakizaki rats. Treatment groups received a single dose of the peroxynitrite decomposition catalyst 5,10,15,20-tetrakis(4-sulfonatophenyl)prophyrinato iron (III), the nonspecific NF-κB inhibitor curcumin, or the broad-spectrum MMP inhibitor minocycline at reperfusion. Poststroke infarct volume, edema, hemorrhage, neurological deficits, and MMP-9 activity were evaluated. All acute treatments reduced MMP-9 and hemorrhagic transformation in diabetic groups. In addition, acute curcumin and minocycline therapy reduced edema in these animals. Improved neurological function was observed in varying degrees with treatment, as indicated by beam-walk performance, modified Bederson scores, and grip strength; however, infarct size was similar to untreated diabetic animals. In control animals, all treatments reduced MMP-9 activity, yet bleeding was not improved. Neuroprotection was only conferred by curcumin and minocycline. Uncovering the underlying mechanisms contributing to the success of acute therapy in diabetes will advance tailored stroke therapies. PMID:23335797

    Minocycline, a broad-spectrum antibiotic used in the treatment of acne and periodontal disease and to control inflammatory diseases such as rheumatoid arthritis, has recently been shown to induce a spectrum of adverse health effects. In the light of these contradictory data, this research was directed to provide basic information on the toxicology of minocycline, using in vitro cell culture models, and to evaluate its efficacy in periodontal therapies, particularly for wound healing. The human gingival epithelioid S-G cell line was used as the bioindicator. The greater toxicity of minocycline over doxycycline and tetracycline, related antimicrobial agents, probably correlated with its higher lipophilicity. The cytotoxicity of minocycline was unaffected by an S9 hepatic microsomal fraction, indicating that it is a direct-acting, rather than a metabolism-mediated, cytotoxicant. In comparative toxicity studies, much variation in the degree of sensitivity to minocycline was noted for different cell types. No correlation in the extent of sensitivity to minocycline and the physiologic state of the bioindicator cell (normal, transformed or malignant) was noted. The toxicity of minocycline to the S-G cells was dependent on its concentration and length of exposure. For a continuous 3-day exposure of the S-G cells to minocycline, the midpoint cytotoxicity (or, NR(50)) value, as quantified in the neutral red (NR) assay, was 204 microg/ml on day 1, 84 microg/ml on day 2, and 59 microg/ml on day 3. For a 1-h exposure of the S-G cells in phosphate buffered saline (PBS), the NR(50) value was 780 microg/ml minocycline. Although a 1-h exposure in PBS to 200 microg/ml minocycline exerted some toxicity, the S-G cells recovered on exposure to growth medium; irreversible, progressive damage occurred at 400 microg/ml minocycline and greater. Minocycline, at 50 microg/ml, enhanced attachment of the S-G cells to a gelatin-coated surface and cell migration towards an immobilized

    Symptoms of alcohol withdrawal range in severity from mild "hangover" to fatal delirium tremens (DTs). Tremor, hallucinosis, and seizures usually occur within 48 hours of abstinence. Seizures tend to be generalized without focality, occurring singly or in a brief cluster, but status epilepticus is not unusual. DTs usually appears after 48 hours of abstinence and consists of marked inattentiveness, agitation, hallucinations, fluctuating level of alertness, marked tremulousness, and sympathetic overactivity. The mainstay of treatment for alcohol withdrawal is benzodiazepine pharmacotherapy, which can be used to control mild early symptoms, to prevent progression to DTs, or to treat DTs itself. Alternative less evidence-based pharmacotherapies include phenobarbital, anticonvulsants, baclofen, gamma-hydroxybutyric acid, beta-blockers, alpha-2-agonists, and N-methyl-d-aspartate receptor blockers. Treatment of DTs is a medical emergency requiring heavy sedation in an intensive care unit, with close attention to autonomic instability, fever, fluid loss, and electrolyte imbalance. Frequent comorbid disorders include hypoglycemia, liver failure, pancreatitis, sepsis, meningitis, intracranial hemorrhage, and Wernicke-Korsakoff syndrome.

    Abstract An increasing number of therapies for spinal cord injury (SCI) are emerging from the laboratory and seeking translation into human clinical trials. Many of these are administered as soon as possible after injury with the hope of attenuating secondary damage and maximizing the extent of spared neurologic tissue. In this article, we systematically review the available pre-clinical research on such neuroprotective therapies that are administered in a non-invasive manner for acute SCI. Specifically, we review treatments that have a relatively high potential for translation due to the fact that they are already used in human clinical applications, or are available in a form that could be administered to humans. These include: erythropoietin, NSAIDs, anti-CD11d antibodies, minocycline, progesterone, estrogen, magnesium, riluzole, polyethylene glycol, atorvastatin, inosine, and pioglitazone. The literature was systematically reviewed to examine studies in which an in-vivo animal model was utilized to assess the efficacy of the therapy in a traumatic SCI paradigm. Using these criteria, 122 studies were identified and reviewed in detail. Wide variations exist in the animal species, injury models, and experimental designs reported in the pre-clinical literature on the therapies reviewed. The review highlights the extent of investigation that has occurred in these specific therapies, and points out gaps in our knowledge that would be potentially valuable prior to human translation.

    Abstract Aceruloplasminemia is an autosomal recessive disorder of iron metabolism caused by mutations in the ceruloplasmin gene. Its prevalence is 1 in 2,000,000 people in Japan. This is a disorder of neurodegeneration with iron accumulation in the brain revealed by MRI. The iron overload induces oxidative stress and generation of reactive oxygen species, which triggers a cascade of pathological events that lead to neuronal death. Intravenous administration of an iron chelator, deferoxamine has been proposed as a method of inhibiting the accumulation of iron. The patient was a 46-year-old Japanese woman. She was diagnosed at the age of 33 years. Deferoxamine was administrated for 6 months but was discontinued due to adverse effects. On admission at the age of 46, psychomotor excitement was acute in onset. The extrapyramidal symptoms reflected iron deposition in the basal ganglia and substantia nigra in the midbrain. Ataxia and a wide-based gate reflected iron deposition in the dentate nuclei of the cerebellum. An antibiotic, minocycline at 150 mg/day successfully ameliorated the clinical symptoms. Minocycline, a second generation tetracycline, has a direct radical scavenging property due to its chemical structure. It has been reported that minocycline is similar to deferoxamine in its ability to chelate iron. Minocycline is also involved in preventing the upregulation of proinflammatory cytokines. The iron-chelating, antioxidant, and anti-inflammatory effects of minocycline were involved in this case. PMID:27175663

    This study investigates the molecular mechanisms by which minocycline, a second generation tetracycline, prevents cardiac myocyte death induced by in utero cocaine exposure. Timed mated pregnant Sprague-Dawley (SD) rats received one of the following treatments twice daily from embryonic (E) day 15–21 (E15–E21): (i) intraperitoneal (IP) injections of saline (control); (ii) IP injections of cocaine (15 mg/kg BW); and (iii) IP injections of cocaine + oral administration of 25 mg/kg BW of minocycline. Pups were killed on postnatal day 15 (P15). Additional pregnant dams received twice daily IP injections of cocaine (from E15–E21) + oral administration of a relatively higher (37.5 mg/kg BW) dose of minocycline. Minocycline treatment continued from E15 until the pups were sacrificed on P15. In utero cocaine exposure resulted in an increase in oxidative stress and fetal cardiac myocyte apoptosis through activation of c-Jun-NH2-terminal kinase (JNK) and p38 mitogen-activated protein kinase (MAPK)-mediated mitochondria-dependent apoptotic pathway. Continued minocycline treatment from E15 through P15 significantly prevented oxidative stress, kinase activation, perturbation of BAX/BCL-2 ratio, cytochrome c release, caspase activation, and attenuated fetal cardiac myocyte apoptosis after prenatal cocaine exposure. These results demonstrate in vivo cardioprotective effects of minocycline in preventing fetal cardiac myocyte death after prenatal cocaine exposure. Given its proven clinical safety and ability to cross the placental barrier and enter into the fetal circulation, minocycline may be an effective therapy for preventing cardiac consequences of in utero cocaine exposure.

    The objective of this study was to investigate the effect of Minocycline in the life span, motor activity, and lipid peroxidation of Drosophila melanogaster treated with manganese. Two days after emerging from the pupa male wild-type D. melanogaster were fed for 13 days with corn media containing 15 mM manganese. Then, they were divided in six groups of 300 flies each: group (a) remained treated with manganese (Mn group); group (b) began treatment with Minocycline (0.05 mM) (Mn-Minocycline group); group (c) received no additional treatment (Mn-no treatment group); group (d) simultaneously fed with manganese and Minocycline (Mn+Minocycline group). Additionally, a control (group e) with no treatment and another group (f) fed only with Minocycline after emerging from the pupa were added. All the manganese treated flies (group a) were dead on the 25th day. The life span in group f (101.66±1.33 days, mean S.E.M.) and of group b (97.00±3.46 days) were similar, but in both cases it was significantly higher than in group e (68.33±1.76 days), group c (67.05±2.30 days) and in those of group d (37.33±0.88). Manganese (groups a and d) decreased motor activity in D. melanogaster. In the Minocycline fed flies (groups b and f) a higher motor activity was detected. In Mn-Minocycline and Mn+Minocycline treated flies a significant decrease of MDA levels was detected when compared to the Minocycline group indicating that Minocycline and Mn appear to have a synergistic effect. In conclusion, Minocycline increased the life span and motor activity and decreased MDA formation of manganese treated D. melanogaster, probably by an inhibition of the production of reactive oxygen species. Manganese also exerted an antioxidant effect as shown by the significant decrease of MDA levels when compared to control flies.

  15. Microbiology and Treatment of Acute Apical Abscesses

    SUMMARY Acute apical abscess is the most common form of dental abscess and is caused by infection of the root canal of the tooth. It is usually localized intraorally, but in some cases the apical abscess may spread and result in severe complications or even mortality. The reasons why dental root canal infections can become symptomatic and evolve to severe spreading and sometimes life-threatening abscesses remain elusive. Studies using culture and advanced molecular microbiology methods for microbial identification in apical abscesses have demonstrated a multispecies community conspicuously dominated by anaerobic bacteria. Species/phylotypes commonly found in these infections belong to the genera Fusobacterium, Parvimonas, Prevotella, Porphyromonas, Dialister, Streptococcus, and Treponema. Advances in DNA sequencing technologies and computational biology have substantially enhanced the knowledge of the microbiota associated with acute apical abscesses and shed some light on the etiopathogeny of this disease. Species richness and abundance and the resulting network of interactions among community members may affect the collective pathogenicity and contribute to the development of acute infections. Disease modifiers, including transient or permanent host-related factors, may also influence the development and severity of acute abscesses. This review focuses on the current evidence about the etiology and treatment of acute apical abscesses and how the process is influenced by host-related factors and proposes future directions in research, diagnosis, and therapeutic approaches to deal with this disease.

    This study was initiated due to an NIH "Facilities of Research--Spinal Cord Injury" contract to support independent replication of published studies that could be considered for a clinical trial in time. Minocycline has been shown to have neuroprotective effects in models of central nervous system injury, including in a contusive spinal cord injury (SCI) model at the thoracic level. Beneficial effects of minocycline treatment included a significant improvement in locomotor behavior and reduced histopathological changes [Lee, S.M., Yune, T.Y., Kim, S.J., Park, D.O.W., Lee, Y.K., Kim, Y.C., Oh, Y.J., Markelonis, G.J., Oh, T.H., 2003. Minocycline reduces cell death and improves functional recovery after traumatic spinal cord injury in the rat. J Neurotrauma. 20, 1017-1027.] To verify these important observations, we repeated this study in our laboratory. The NYU (MASCIS) Impactor was used to produce a moderate cord lesion at the vertebral level T9-T10 (height 12.5 mm, weight 10 g), (n=45), followed by administration of minocycline, 90 mg/kg (group 1: minocycline IP, n=15; group 2: minocycline IV, n=15; group 3: vehicle IP, n=8; group 4: vehicle IV, n=7) immediately after surgery and followed by two more doses of 45 mg/kg/IP at 12 h and 24 h. Open field locomotion (BBB) and subscores were examined up to 6 weeks after SCI and cords were processed for quantitative histopathological analysis. Administration of minocycline after SCI did not lead to significant behavioral or histopathological improvement. Although positive effects with minocycline have been reported in several animal models of injury with different drug administration schemes, the use of minocycline following contusive SCI requires further investigation before clinical trials are implemented.

    Hyperpigmentation associated with prolonged minocycline use is well documented. The histopathology of cutaneous minocycline pigment is characterized by deposition of brown/black, Fontana-Masson, and Perls' positive granules deposited along elastic fibers in the papillary dermis and occurring within macrophages along vessels and eccrine units in the dermis. The subcutis may also be involved; however, the specific subcutaneous findings associated with minocycline hyperpigmentation have not been well established. We present the histopathologic findings of 4 cases of minocycline hyperpigmentation with subcutaneous involvement. Green-gray, flocculent, nonrefractile globules within macrophages were found in the subcutis of all patients. Two of 4 cases exhibited lipomembraneous changes that were also associated with pigment. These distinctive findings may provide additional clues to enable a diagnosis of drug-induced hyperpigmentation to be offered, even in the absence of a clear clinical history. PMID:17939935

    Autism is a neurodevelopment disorder. One percent worldwide population suffers with autism and males suffer more than females. Microglia plays an important role in neurodevelopment, neuropsychiatric and neurodegenerative disorders. The present study has been designed to investigate the role of minocycline in prenatal valproic acid induced autism in rats. Animals with prenatal valproic acid have reduced social interaction (three chamber social behaviour apparatus), spontaneous alteration (Y-Maze), exploratory activity (Hole board test), intestinal motility, serotonin levels (both in prefrontal cortex and ileum) and prefrontal cortex mitochondrial complex activity (complexes I, II, IV). Furthermore, prenatal valproic acid treated animals have shown an increase in locomotion (actophotometer), anxiety (elevated plus maze), brain oxidative stress (thiobarbituric acid reactive species, glutathione, catalase), nitrosative stress (nitrite/nitrate), inflammation (both in brain and ileum myeloperoxidase activity), calcium and blood brain barrier permeability. Treatment with minocycline significantly attenuated prenatal valproic acid induced reduction in social interaction, spontaneous alteration, exploratory activity intestinal motility, serotonin levels and prefrontal cortex mitochondrial complex activity. Furthermore, minocycline has also attenuated prenatal valproic acid induced increase in locomotion, anxiety, brain oxidative and nitrosative stress, inflammation, calcium and blood brain barrier permeability. Thus, it may be concluded that prenatal valproic acid has induced autistic behaviour, biochemistry and blood brain barrier impairment in animals, which were significantly attenuated by minocycline. Minocycline should be explored further for its therapeutic benefits in autism.

    Minocycline is an oral antibiotic widely used for the long-term treatment of acne vulgaris. Unusual side effects of this medication include two overlapping autoimmune syndromes: drug-induced lupus and autoimmune hepatitis. In addition, in a few patients livedo reticularis or subcutaneous nodules have developed in association with arthritis and serum perinuclear antineutrophil cytoplasmic antibodies (P-ANCA) during long-term minocycline therapy. We report the cases of two young women receiving long-term minocycline therapy (>3 years) in whom P-ANCA-positive cutaneous polyarteritis nodosa developed. Both patients presented with a violaceous reticulated pattern on the lower extremities. Histologic examination of biopsy specimens from a reticulated area and a subcutaneous nodule showed necrotizing vasculitis of medium-sized arteries in the deep dermis, consistent with the diagnosis of polyarteritis nodosa. The cutaneous lesions rapidly resolved on discontinuation of minocycline and initiation of prednisone therapy. A high index of suspicion and testing for antineutrophil cytoplasmic antibody in addition to the standard antinuclear antibody panel can facilitate diagnosis of minocycline-related autoimmune disorders.

    Pseudotumor cerebri is a syndrome characterized by an elevated intracranial pressure greater than 20 cmH2O with ventricles and cerebrospinal fluid of normal characteristics. Consumption of minocycline have been described among the causes associated with this syndrome. We present a 13-year old female patient with a history of acne treated with minocycline who began with severe headache, diplopia and blurred vision. The diagnosis of pseudotumor cerebri was made, indicating the immediate antibiotic suspension and the beginning of the treatment with acetazolamide. Although the pathogenesis of pseudotumor cerebri is not fully known, an association with minocycline has been observed. This antibiotic is often used by health professionals for the management of acne, so it is important to consider its complications before being prescribed.

    Diagnosis and treatment results of 57 patients with acute diffuse brain injury have been analyzed. Patients were divided into two groups: first study period 2000-2005; second study period 2006-2010. The main differences between the first and the second study periods were in health condition and brain functions monitoring parameters, therapy approaches and goals. Increasing of axial and lateral dislocation symptoms during progression from the first type of diffuse injury to the fourth one is related to intracranial hypertension (ICH) occurrence rate and significance it's significance. During the second study period, ICH was found in 25% patients with the second type of injury, 57% patients with the third type of injury, and 80%, with the fourth type of injury. Mean ICP in the group of patients with the second type of diffuse injury comprised 14.4 +/- 6.6 mmHg; with the third type of injury, 30 +/- 20.6 mmHg; with the fourth type of injuty, 37.6 +/- 14.1 mmHg. Introduction of differentiated approach to conservative or surgical treatment method application to acute diffuse brain injuries patients based on ICP monitoring data led to 13.8% reduction in mortality in the second study period compared with the first study period.

    This article focuses on the pathogenesis, clinical manifestations, and various treatment modalities for acute hyperkalemia and presents a systematic approach to selecting a treatment strategy. Hyperkalemia, a life-threatening condition caused by extracellular potassium shift or decreased renal potassium excretion, usually presents with non-specific symptoms. Early recognition of moderate to severe hyperkalemia is vital in preventing fatal cardiac arrhythmias and muscle paralysis. Management of hyperkalemia includes the elimination of reversible causes (diet, medications), rapidly acting therapies that shift potassium into cells and block the cardiac membrane effects of hyperkalemia, and measures to facilitate removal of potassium from the body (saline diuresis, oral binding resins, and hemodialysis). Hyperkalemia with potassium level more than 6.5 mEq/L or EKG changes is a medical emergency and should be treated accordingly. Treatment should be started with calcium gluconate to stabilize cardiomyocyte membranes, followed by insulin injection, and b-agonists administration. Hemodialysis remains the most reliable method to remove potassium from the body and should be used in cases refractory to medical treatment. Prompt detection and proper treatment are crucial in preventing lethal outcomes. PMID:23882341

    Migraine is a common disabling primary headache disorder. Despite the need for a perfect treatment of this debilitating condition, the ideal “cure” eludes us. In 1992, the first triptan was released in the US for use in acute migraine. Triptans are more specific for the serotonin receptor 5-hydroxy triptamine (5-HT) 1 than previously prescribed drugs, such as ergotamines, with fewer side effects. This was an important first step in specific acute migraine therapy. Today however, triptans continue to be underutilized. There remains a concern, among practitioners and patients, about possible cardiovascular safety issues, despite the lack of strong evidence of serious adverse events. In fact, triptans now have a safe track record over more than a decade of use. Other perceived downfalls to use, include cost and variable efficacy. The more we learn about the clinical features and pathophysiology of migraine, the closer we are to finding a satisfactory monotherapy. Until then, recognizing that mixed mechanisms underlie migraine symptoms, rational polytherapy can be useful. Research on the roles of serotonin, calcitonin gene related peptide, glutamine and N-methyl-D-aspartate in the trigeminovascular system holds promise for those searching for the perfect migraine headache cure.

    Background and Purpose Cerebral Amyloid Angiopathy (CAA) is a common cause of recurrent intracerebral hemorrhage (ICH) in the elderly. Previous studies have shown that CAA induces inflammation and expression of matrix metalloproteinase-2 and -9 (gelatinases) in amyloid-laden vessels. Here, we inhibited both using minocycline in CAA mouse models to determine if spontaneous ICH could be reduced. Methods Tg2576 (n=16) and 5×FAD/ApoE4 knock-in mice (n=16), aged to 17 and 12 months, respectively, were treated with minocycline (50 mg/kg, i.p.) or saline every other day for two months. Brains were extracted and stained with X-34 (to quantify amyloid), Perl’s blue (to quantify hemorrhage), and immunostained to examined Aβ load, gliosis (GFAP, Iba-1), and vascular markers of blood-brain-barrier integrity (ZO-1 and collagen IV). Brain extracts were used to quantify mRNA for a variety of inflammatory genes. Results Minocycline treatment significantly reduced hemorrhage frequency in the brains of Tg2576 and 5×FAD/ApoE4 mice relative to the saline-treated mice, without affecting CAA load. Gliosis (GFAP and Iba-1 immunostaining), gelatinase activity, and expression of a variety of inflammatory genes (MMP-9, Nox4, CD45, S-100b, Iba-1) were also significantly reduced. Higher levels of microvascular tight junction and basal lamina proteins were found in the brains of minocycline-treated Tg2576 mice relative to saline-treated controls. Conclusions Minocycline reduced gliosis, inflammatory gene expression, gelatinase activity, and spontaneous hemorrhage in two different mouse models of CAA, supporting the importance of MMP-related and inflammatory pathways in ICH pathogenesis. As an FDA-approved drug, minocycline might be considered for clinical trials to test efficacy in preventing CAA-related ICH. PMID:25944329

    A 20-year-old woman presented with a heavily pigmented scar on the left lower abdomen following excision of a benign compound nevus. Reexcision showed an organizing scar with pronounced hemosiderinlike pigment deposition and no residual melanocytic lesion. Results of further histopathologic workup showed positive staining with both Perls stain for iron and Fontana-Masson stain. These findings led to further questioning of the patient, which revealed a history of minocycline therapy--information that had not been provided during her initial evaluation. Hyperpigmented scars may result from minocycline ingestion. We present a review of the literature, with particular regard to the possible mechanisms of minocycline hyperpigmentation and the differential diagnosis of hyperpigmented scars.

  8. Endovascular treatment of acute ischemic stroke.

    2016-01-01

    Endovascular thrombectomy is an effective treatment for major acute ischemic stroke syndromes caused by major anterior circulation artery occlusions (commonly referred to as large vessel occlusion) and is superior to intravenous thrombolysis and medical management. Treatment should occur as quickly as is reasonably possible. All patients with moderate to severe symptoms (National Institutes of Health stroke scale >8) and a treatable occlusion should be considered. The use of neuroimaging is critical to exclude hemorrhage and large ischemic cores. Very shortly after stroke onset (<3 hours) computed tomography (CT) and CT angiography provide sufficient information to proceed; diffusion magnetic resonance imaging (MRI) is less reliable during this early stage. After 3 hours from onset diffusion MRI is the most reliable method to define ischemic core size and should be used in centers that can offer it rapidly. Recanalization is highly effective with a stentriever or using a direct aspiration technique, with the patient awake or under conscious sedation rather than general anesthesia, if it may be performed safely. After thrombectomy the patient should be admitted to an intensive care setting and inpatient rehabilitation undertaken as soon as feasible. Patient outcomes should be assessed at 3 months, preferably using the modified Rankin score. PMID:27430469

    Injuries to the acromioclavicular joint occur commonly in athletes, especially those involved in contact sports. The majority of these injuries are type I and II acromioclavicular joint separations and are treated nonoperatively with rehabilitation. A rapid and full return to play is expected. Acute types IV, V, and VI are less common and operative intervention is recommended. The type III injury is more controversial and current trends are towards initial nonoperative management. Operative treatment is sought only when the athlete remains symptomatic with painful instability. However, some do support early intervention in the overhead athlete. The goal of operative intervention is to create a stiff and strong repair/reconstruction of the coracoclavicular ligaments while providing stability in all planes. This will allow early and more aggressive rehabilitation. Surgical treatment includes reconstruction of the coracoclavicular ligaments with an augmented coracoacromial ligament transfer and more recently tendon graft reconstructions. Biomechanical research supports an anatomic reconstruction of the ligaments to confer the most function and stability.

    Acute pancreatitis (AP) has a fast onset and progression, which lead to an unfavorable prognosis. Therefore, the development of novel drugs for its treatment is critical. As a homologous derivative of resveratrol, pterostilbene exerts a variety of effects including anti-inflammatory, antioxidant, and antitumor effects. This study investigated the potential of pterostilbene for treatment of severe AP (SAP) and related mechanisms. Effects of pterostilbene were evaluated in a Wistar rat model of AP. Serum levels of amylase (AMY), creatinine (Cr), and alanine aminotransferase (ALT) were quantified. Furthermore, serum levels of tumor necrosis factor (TNF)-a and interleukin (IL)-1b were quantified using enzyme-linked immunosorbent assay. Nuclear factor (NF)-kB expression in pancreatic tissues was quantified by real-time PCR and western blotting. The production of reactive oxygen species (ROS) was determined using a spectrometer, while superoxide dismutase (SOD) activity was assayed. In the AP rat model, the expression of inflammatory markers TNF-a and IL-1b, expression of NF-kB, and serum indices (AMY, Cr, and ALT) increased compared to the corresponding levels in the control group (P < 0.05). Pterostilbene reduced serum levels of TNF-a and IL-1b; decreased NF-kB gene expression, serum indices, and ROS generation; and increased SOD activity in a dose-dependent manner. In conclusion, pterostilbene can alleviate SAP-induced tissue damage by decreasing the inflammatory response and by promoting antioxidation leading to the protection of pancreatic tissues.

    The mechanisms associated with diabetes-induced neuropathic pain are complex and poorly understood. In order to understand the involvement of spinal microglia activity in diabetic pain, the present study investigated whether minocycline treatment is able to attenuate diabetic pain using a rat model. Diabetes was induced using a single intraperitoneal injection of streptozotocin (STZ). Minocycline was then intrathecally administered to the rats. Paw withdrawal threshold (PWT) and paw withdrawal latency (PWL) were tested weekly. The expression of OX-42, Iba-1, phospho-p38 mitogen-activated protein kinase (MAPK), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and inducible nitric oxide synthase (iNOS), were examined in the spinal cord in order to evaluate the activation of microglia. The present study demonstrated that rats with STZ-induced diabetes exhibited increased mean plasma glucose concentration, decreased mean body weight and significant pain hypersensitivity compared with control rats. PWT and PWL values of rats with STZ-induced diabetes increased following treatment with minocycline. No differences were observed in expression levels of the microglial activity markers (OX-42, Iba-1 and phospho-p38 MAPK) between rats with STZ-induced diabetes and control rats. However, TNF-α, IL-1β and iNOS expression levels were higher in rats with STZ-induced diabetes compared with control rats. Following treatment with minocycline markers of microglial activation, including cytokines and iNOS, were downregulated in rats with STZ-induced diabetes. The results of the present study indicated that minocycline treatment may inhibit spinal microglial activation and attenuate diabetic pain in rats with STZ-induced diabetes.

    Antimicrobial resistance among Acinetobacter baumannii is increasing worldwide, often necessitating combination therapy. The clinical utility of using minocycline with polymyxin B is not well established. In this study, we investigated the activity of minocycline and polymyxin B against 1 laboratory isolate and 3 clinical isolates of A. baumannii. Minocycline susceptibility testing was performed with and without an efflux pump inhibitor, phenylalanine-arginine β-naphthylamide (PAβN). The intracellular minocycline concentration was determined with and without polymyxin B (0.5 μg/ml). Time-kill studies were performed over 24 h using approximately 106 CFU/ml of each strain with clinically relevant minocycline concentrations (2 μg/ml and 8 μg/ml), with and without polymyxin B (0.5 μg/ml). The in vivo efficacy of the combination was assessed in a neutropenic murine pneumonia model. Infected animals were administered minocycline (50 mg/kg), polymyxin B (10 mg/kg), or both to achieve clinically equivalent exposures in humans. A reduction in the minocycline MIC (≥4×) was observed in the presence of PAβN. The intracellular concentration and in vitro bactericidal effect of minocycline were both enhanced by polymyxin B. With 2 minocycline-susceptible strains, the bacterial burden in lung tissue at 24 h was considerably reduced by the combination compared to monotherapy with minocycline or polymyxin B. In addition, the combination prolonged survival of animals infected with a minocycline-susceptible strain. Polymyxin B increased the intracellular concentration of minocycline in bacterial cells and enhanced the bactericidal activity of minocycline, presumably due to efflux pump disruption. The clinical utility of this combination should be further investigated. PMID:25712362

    Dysfunction of learning and memory is widely found in many neurological diseases. Understanding how to preserve the normal function of learning and memory will be extremely beneficial for the treatment of these diseases. However, the possible protective effect of minocycline in memory impairment is unknown. We used the well-established D-galactose rat amnesia model and two behavioral tasks, the Morris water maze and the step-down task, for memory evaluation. Western blot and PCR were used to examine the protein and mRNA levels of Arc/Arg3.1. We report that minocycline supplementation ameliorates both the spatial and fear memory deficits caused by D-galactose. We also found that Arc/Arg3.1, c-fos, and brain-derived neurotrophic factor levels are decreased in the D-galactose animal model, and that minocycline reverses the protein and mRNA levels of Arc in the hippocampus, suggesting the potential role of Arc/Arg3.1 in minocycline's neuroprotective mechanism. Our study strongly suggests that minocycline can be used as a novel treatment for memory impairment in neurological diseases.

    Neural progenitor cell (NPC) transplantation offers great potential to treat spinal cord injury (SCI), but their efficiency is limited by poor survival and neuronal differentiation after transplantation. In the injury site, microglia may become activated and participate in the inflammation reaction. In vitro studies indicated that activated microglia might impair NPC survival and neuronal differentiation, but resting microglia did not. This study investigated the potential of minocycline to modify the negative effects of activated microglia on NPCs in vitro. First, the direct effects of minocycline on NPCs were tested. The results showed that at the concentration of 10μg/ml or lower, minocycline did not affect NPC survival and proliferation, but impaired neuronal differentiation. Then microglia were activated with lipopolysaccharide (LPS) or treated with LPS plus minocycline (LPSMC), and the effects of conditioned media on NPC apoptosis and differentiation were studied. The results showed that, compared with LPS treatment group, the microglia conditioned media of LPSMC treatment group resulted in a significantly lower apoptotic rate of NPCs, and increased the neuronal differentiation of NPCs. This suggested that minocycline might inhibit the negative effects of microglia on NPCs, and have the potential to support the survival and neuronal differentiation of transplanted NPCs for SCI.

    Chronic alcohol intoxication (CAI) increases both morbidity and mortality of stroke patients. Despite the high prevalence of CAI and ischemic stroke, studies addressing their comorbidity and/or protective alternatives remain scarce. Thus, the influence of CAI on both stroke outcome and minocycline treatment (recognized for its neuroprotective effect) was investigated. Female Wistar rats (35 days old) were treated with water or ethanol (6.5 g/kg/day, 22.5% w/v) for 55 days. Then, focal ischemia was induced by endothelin-1 in the motor cortex. Two hours later, four doses of 50 mg/kg of minocycline every 12 hours followed by five doses of 25 mg/kg every 24 hours were administered. Behavioral performance (open field and rotarod tests) and immunohistochemical (cellular density, neuronal death, and astrocytic activation) and biochemical (lipid peroxidation and nitrite levels) analyses were performed. CAI increased motor disruption, nitrite and lipid peroxidation levels, and neuronal loss caused by ischemia, whereas it reduced the astrogliosis. Minocycline was effective in preventing the motor and tissue damage caused by stroke. However, these effects were attenuated when CAI preceded stroke. Our data suggest that CAI beginning in adolescence contributes to a worse outcome in ischemic stroke survivors and reduces the benefits of minocycline, possibly requiring adjustments in therapy.

    Relapse to drug use is one of the most difficult clinical problems in treating addiction. Glial activation has been linked with the drug abuse, and the glia modulators such as minocycline can modulate the drug abuse effects. The aim of the present study was to determine whether minocycline could attenuate the maintenance and reinstatement of morphine. Conditioned place preference (CPP) was induced by subcutaneous injection of morphine (5 mg/kg) for 3 days. Following the acquisition of the CPP, the rats were given daily bilateral intra-NAc injections of either minocycline (1, 5, and 10 μg/0.5 μL) or saline (0.5 μL). The animals were tested for conditioning score 60 min after each injection. To induce the reinstatement, a priming dose of morphine (1 mg/kg) was injected 1 day after the final extinction day. The morphine-induced CPP lasted for 7 days after cessation of morphine treatment. Our data revealed that a priming dose of morphine could reinstate the extinguished morphine-induced CPP. Daily intra-accumbal injection of minocycline during the extinction period blocked the maintenance of morphine CPP and also attenuated the priming-induced reinstatement. Our findings indicated that minocycline could facilitate the extinction and attenuate the reinstatement of morphine. These results provided new evidence that minocycline might be considered as a promising therapeutic agent for the treatment of several symptoms associated with morphine abuse. PMID:26745749

  18. Evolving Role of Endovascular Treatment of Acute Ischemic Stroke

    2014-01-01

    The perceived advantages of endovascular treatment for acute ischemic stroke in terms of recanalization, the multimodal and targeted approaches, and perhaps the more permissive rules on devices than on medications for their licensing favored the assumption that endovascular treatment is superior to intravenous thrombolysis for acute treatment of ischemic stroke, and its adoption in more advanced stroke centers. However, this assumption has been questioned by recent clinical trial experience showing that endovascular treatment is not superior to intravenous thrombolysis. The new evidence has changed the perception and the importance of conducting randomized trials in this area. This summary examines the background and outcomes of the latest experience with endovascular techniques in acute stroke treatment based on historical data. The new challenge is how to study the latest generation of devices called stent retrievers, which are faster in recanalizing and easier to use, in selected patients with acute ischemic stroke. In the meantime, the available evidence does not provide support for the use of endovascular treatment of acute ischemic stroke in clinical practice. PMID:24258466

    OBJECTIVE—To determine prospectively the efficacy of surfactant in acute respiratory distress syndrome.
STUDY DESIGN—Twenty patients, 1 month to 16 years of age, diagnosed with an acute pulmonary disease with severe hypoxaemia (PaO2/FiO2 < 100) (13 with systemic or pulmonary disease and seven with cardiac disease) were treated with one to six doses of 50-200 mg/kg of porcine surfactant administered directly into the trachea. The surfactant was considered to be effective when the PaO2/FiO2 improved by > 20%.
RESULTS—After initial surfactant administration the PaO2/FiO2 increased significantly in patients with systemic or pulmonary disease from 68 to 111, and the oxygenation index (OI) diminished significantly from 36.9 to 27.1. The PaO2/FiO2 and OI did not improve in children with cardiac disease. The improvement of the patients who survived was greater than that of those who died.
CONCLUSIONS—Surfactant moderately improves oxygenation in some children with severe acute respiratory distress syndrome secondary to pulmonary or systemic disease.

    The objective of this study was to describe the main lesions that simulate clinically and propose a treatment protocol for acute endodontic infection. Signs and clinical symptoms of periodontal abscess, gingival abscess, odontoma, herpes simplex, pericoronitis, acute pulpitis and necrotizing ulcerative gingivitis/periodontitis (NUG/NUP) were described and compared with acute endodontic infections. A treatment protocol was described by optimizing the procedures in access cavity, microbial decontamination and detoxification of the root canal, apical debridement, intracanal and systemic medication and surgical drainage procedures. The convenience of the use of 5.25% sodium hypochlorite, root canal instrumentation using a crown-down technique, intracanal medication with 2% chlorhexidine or triple antibiotic paste and the convenience of the use of antibiotics, analgesics, and surgical drainage to solve cases of acute dentoalveolar abscess was discussed.

    2011-06-01

    Treatment with the chemotherapeutic agent oxaliplatin produces a robust painful neuropathy similar to various other neuropathic conditions which result in loss of nerve fibers innervating the skin. This loss of intraepidermal nerve fibers (IENFs) appears to play an important role in neuropathy, but has yet to be investigated in oxaliplatin-induced neuropathic pain. For this study, mechanical hyperalgesia and IENF density were measured in rats receiving oxaliplatin, given at a dosage of 2 mg/kg every other day for four injections. The immunomodulatory agent minocycline (25 mg/kg) was also administered and was given 24 h prior to the first dose of oxaliplatin and continued throughout oxaliplatin treatment. Immunohistochemistry using the pan-neuronal marker PGP9.5 was used to investigate IENF densities in hind paw skin on Day 15 and Day 30. The results show that a robust mechanical sensitivity developed in oxaliplatin treated animals, as did a pronounced decrease in epidermal nerve fibers, and these outcomes were effectively prevented by minocycline treatment. This is the first study to show changes in IENF density in oxaliplatin treated animals, and confirm not only a relationship between IENF loss and hypersensitivity but also prevention of both with minocycline treatment.

    Minocycline (MCN) is a member of the tetracycline family that is commonly used to treat dermatologic conditions such as acne and perioral dermatitis; however, it also has been associated with a number of adverse effects, including drug reaction with eosinophilia and systemic symptoms (DRESS). We report the case of a 46-year-old woman who developed a rash, fever, and eosinophilia during treatment with MCN for perioral dermatitis. Although MCN was discontinued and the patient was administered oral corticosteroids for several months, she subsequently died from multiorgan failure with giant cell myocardi-tis (GCM) and eosinophilic myocarditis found on autopsy. This article highlights a rare consequence of hypersensitivity to a commonly used drug and illustrates the importance of rapid recognition and aggressive management of MCN-induced DRESS.

    The present study aimed to investigate the mechanism underlying the effects of minocycline on diabetic retinopathy-associated cellular apoptosis. A total of 40 Sprague Dawley (SD) rats were used as a diabetic retinopathy model following injection with streptozotocin. Among the 34 rats in which the diabetes model was successfully established, 24 rats were divided into two experimental groups: I and II (T1 and T2, respectively), and orally administered with various doses of minocycline. The remaining 10 rats served as the diabetic retinopathy control group. An additional group of 10 healthy SD rats with comparable weight served as normal controls. The rats in T1 and T2 groups were treated daily for eight consecutive weeks with minocycline at a dose of 2.5 mg/kg and 5 mg/kg, respectively. The mRNA expression levels of poly (ADP-ribose) polymerase-1 (PARP-1) were subsequently measured by reverse transcription-quantitative polymerase chain reaction, and the protein expression levels of poly-ADP-ribose were measured by western blot analysis and immunohistochemistry. Retinal morphology was observed following hematoxylin and eosin staining, and retinal cell apoptosis was measured by terminal deoxynucleotidyl transferase dUTP nick end labeling and caspase-3 activity assays. The amplitudes of the electroretinogram (ERG) b-wave and oscillary potentials (OPs) were measured using visual electrophysiology, and compared among the four groups. The results of the present study demonstrated that in the diabetic rats, retinal PARP-1 gene expression was markedly upregulated, the number of apoptotic cells and the activity levels of caspase-3 were increased, and the amplitude of the ERG b-wave and the OPs were markedly lower as compared with the normal rats. Following treatment with minocycline, the abnormal expression of PARP-1 in the retina was inhibited, and cellular apoptosis was decreased. In conclusion, the results of the present study suggest that PARP-1 is involved in the

    Skin biopsy specimens and discolored fingernails from minocycline-treated patients were examined by light and electron microscopy, histochemistry, and energy-dispersive x-ray analysis. Both hyperpigmented and adjacent normally pigmented skin samples contained pigment-laden macrophages in the dermis, although these cells were more numerous in the hyperpigmented skin samples. Elemental analysis showed that both pigment deposits and stratum corneum of hyperpigmented skin samples contained iron and calcium. Discolored areas of fingernails from a minocycline-treated patient also contained iron and calcium. Both skin and nail discoloration were possibly due to the presence of an iron chelate of minocycline and/or quinoid derivatives of minocycline. The presence of iron-containing pigment in normal as well as hyperpigmented skin may have predisposed to formation of minocycline-associated pigment in these patients.

    Faropenem medoxomil is the first oral penem in a new class of beta-lactam antibiotics. Faropenem medoxomil has excellent in vitro activity against Streptococcus pneumoniae, Haemophilus influenzae and other key pathogens implicated in acute bacterial rhinosinusitis. Clinical studies have demonstrated that, in the treatment of acute bacterial rhinosinusitis in adults, 7 days of treatment with faropenem medoxomil is as clinically and bacteriologically effective as 10 days of treatment with cefuroxime axetil. One study showed faropenem medoxomil to be superior to cefuroxime axetil. Overall, the safety profile of faropenem medoxomil is similar to that of most comparators. Specifically, the minimal impact of faropenem medoxomil on the gastrointestinal flora leads to less diarrhea and other adverse events than coamoxicillin-clavulanate. Faropenem medoxomil has almost no drug-drug interactions and little requirement for dosage adjustments in the typical acute rhinosinusitis population. PMID:17181408

    Systemic injection of lipopolysaccharide (LPS) induces a robust immune response as well as thermal and mechanical hyperalgesia. Spinal and peripheral glial cells have been implicated as important mediators in this hyperalgesia but the specific contributions of microglia versus astrocytes are not entirely clear. To better define these mechanisms, this study examined the febrile response, nociceptive sensitivity, glial cell reactivity and cytokine production in the dorsal root ganglion (DRG) and spinal cord in rats following systemic treatment with LPS and the effects of minocycline in countering these responses. Intraperitoneal LPS injection resulted in an increase in core body temperature and produced hyperalgesia to heat and mechanical stimuli. Western blot studies revealed increased expression of microgial cell, macrophage and satellite cell markers in DRG and microglial and astrocyte markers in spinal cord following LPS treatment. Real-time RT-PCR indicated that LPS treatment increased cytokine mRNA expression levels in both the DRG and the spinal cord. Minocycline suppressed all LPS-induced behavioral effects but not the febrile response. Moreover, minocycline prevented LPS-induced microglia/macrophage activation and cytokine responses in spinal cord and DRG, but did not affect the activation of astrocytes/satellite cells. These data demonstrate that LPS-induced changes in nociceptive sensitivity are likely mediated by activation of microglial cells and/or macrophages in the spinal cord and DRG.

    In the era of carbapenem-resistance in Acinobacter baumannii and Enterobacteriaceae, there are limited treatment options for these pathogens. It is essential that clinicians fully assess all available therapeutic alternatives for these multidrug-resistant organisms. We herein describe the approach of the antimicrobial stewardship team at the Detroit Medical Center (DMC) for the evaluation and use of intravenous (IV) minocycline for the treatment of these resistant organisms, given potential advantages of IV minocycline over tigecycline and doxycycline. In vitro analyses at the DMC demonstrated good activity against A. baumannii (78% susceptibility), including 74% of carbapenem-resistant strains, but limited activity against our carbapenem-resistant K.pneumoniae (12% susceptibility.) Based in part on these results, IV minocycline was added to the formulary, primarily for the treatment of carbapenem-resistant A. baumannii. Early experience has been positive: 6/9 (67%) of patients who received IV minocycline had infections due to these organisms cured, including 6/7 (86%) who received doses of 200 mg twice daily.

    Objective: Acute ankle sprains are one of the most common injuries in emergency departments. Immobilization is widely accepted as the basic treatment modality for acute ankle sprains; however, immobilization method remains controversial. In this study, we aimed to compare two treatment modalities: splint and elastic bandage for the management of acute ankle sprains. Methods: This prospective study was conducted in the emergency department. Fifty-one consecutive patients who were admitted to the emergency department owing to the complaint of ankle sprain and who were treated with an elastic bandage or a splint were included in the study. After bone injury was ruled out, treatment choice was left to the on-shift physicians’ discretion. The extent of edema was evaluated before and after the treatment by using a small, graduated container filled with warm water. Volume differences were calculated by immersing both lower extremities in a container filled to a constant level. Pain was evaluated using the visual analogue scale. Results: There were 25 patients in the elastic bandage group and 26 patients in the splint group. VAS scores of these groups before and after the treatment were similar. Although edema size before and after the treatment were similar between the groups, edema size reduction was significantly more in the elastic bandage group [p=0,025]. Conclusions: This study showed that treatment of acute ankle sprains with an elastic bandage was more effective than splint in reducing edema. Therefore, an elastic bandage could be preferred over a splint for the treatment of acute ankle sprains. PMID:26870123

    Endovascular therapy for acute stroke has evolved with the use of intra-arterial thrombolytics, intravenous/intra-arterial bridging strategies, and mechanical thrombectomy/aspiration devices. Despite widespread use in clinical practice, randomized trials of first-generation devices failed to demonstrate improved outcomes compared with standard care. New-generation stent retriever devices demonstrate higher rates of revascularization and clinical outcomes compared with first-generation devices. Additional randomized trials are underway and have the potential to confirm clinical efficacy of new-generation devices compared with standard care. The role of additional advanced imaging for patient selection remains unclear, and further trials are needed to demonstrate the role of these techniques for patient selection. PMID:25907913

    Acute compartment syndrome of the extremities is well known, but diagnosis can be challenging. Ineffective treatment can have devastating consequences, such as permanent dysaesthesia, ischaemic contractures, muscle dysfunction, loss of limb, and even loss of life. Despite many studies, there is no consensus about the way in which acute extremity compartment syndromes should be diagnosed. Many surgeons suggest continuous monitoring of intracompartmental pressure for all patients who have high-risk extremity injuries, whereas others suggest aggressive surgical intervention if acute compartment syndrome is even suspected. Although surgical fasciotomy might reduce intracompartmental pressure, this procedure also carries the risk of long-term complications. In this paper in The Lancet Series about emergency surgery we summarise the available data on acute extremity compartment syndrome of the upper and lower extremities in adults and children, discuss the underlying pathophysiology, and propose a clinical guideline based on the available data.

    Doxycycline, a commonly prescribed tetracycline, remains on intermittent shortage. We systematically reviewed the literature to assess minocycline as an alternative to doxycycline in select conditions, given doxycycline's continued shortage. We identified 19 studies, 10 of which were published before 2000. Thirteen of the studies were prospective, but only 1 of these studies was randomized. Based on the available data, we found minocycline to be a reasonable substitute for doxycycline in the following scenarios: skin and soft-tissue infections and outpatient treatment of community-acquired pneumonia in young, otherwise healthy patients or in patients with macrolide-resistant Mycoplasma pneumoniae, as well as Lyme disease prophylaxis and select rickettsial disease should doxycycline be unavailable.

    2007-12-01

    Leber's hereditary optic neuropathy (LHON) is a retinal neurodegenerative disorder caused by mitochondrial DNA point mutations. Complex I of the respiratory chain affected by the mutation results in a decrease in ATP and an increase of reactive oxygen species production. Evaluating the efficacy of minocycline in LHON, the drug increased the survival of cybrid cells in contrast to the parental cells after thapsigargin-induced calcium overload. Similar protection was observed by treatment with cyclosporine A, a blocker of the mitochondrial permeability transition pore (mPTP). Ratiometric Ca(2+) imaging reveals that acetylcholine/thapsigargin triggered elevation of the cytosolic calcium concentration is alleviated by minocycline and cyclosporine A. The mitochondrial membrane potential of LHON cybrids was significantly conserved and the active-caspase-3/procaspase-3 ratio was decreased in both treatments. Our observations show that minocycline inhibits permeability transition induced by thapsigargin in addition to its antioxidant effects. In relation with its high safety profile, these results would suggest minocycline as a promising neuroprotective agent in LHON.

    Summary Acute thrombosis of cerebral veins and sinuses (ATCVS) is a multifactorial disease with grave consequences. Because of its rare occurrence there are no proven treatment guidelines. Sixteen patients with ATCVS were treated. The final diagnosis was confirmed by digital subtraction angiography. Sinus catheterization was performed via transfemoral venous access. Treatment included mechanical manipulation of thrombi and thrombolytic therapy. A regression of clinical symptoms with a concomitant decrease of intracranial hypertension was achieved in all patients. Long-term results were studied in eight patients: none presented clinical signs of intracranial hypertension. Endovascular transvenous recanalization is an effective treatment for acute thrombosis of cerebral veins and sinuses. Along with the local thrombolysis, significant potential in the treatment of this complex pathology lies in the transvenous endovascular techniques of mechanical thrombus extraction, especially in patients with intracranial hemorrhage for whom the use of thrombolytic agents is restricted.

    Abstract Question A 3-year-old was rushed to my office after eating a friend’s chocolate bar that contained nuts. He immediately developed urticaria on his face and swelling of his lips, and he had a persistent cough. What is the best treatment for a child with anaphylaxis? Should this family receive a prescription for an epinephrine autoinjector device? Answer Intramuscular epinephrine injection is a safe and effective treatment of anaphylaxis in children. Children with systemic allergic reactions should carry epinephrine autoinjectors at all times, and should certainly have one with them at school. In order for epinephrine autoinjectors to be effective, children and their families need to be educated on how to properly use the devices, as well as keep in mind the product’s expiration date.

    Abstract The goal of this study was to compare the effects of minocycline and simvastatin on functional recovery and brain gene expression after a cortical contusion impact (CCI) injury. Dosage regimens were designed to provide serum concentrations in a rat model in the range obtained with clinically approved doses; minocycline 60 mg/kg q12h and simvastatin 10 mg/kg q12h for 72 h. Functional recovery was assessed using motor and spatial learning tasks and neuropathological measurements. Microarray-based transcriptional profiling was used to determine the effect on gene expression at 24 h, 72 h, and 7 days post-CCI. Gene Ontology analysis (GOA) was used to evaluate the effect on relevant biological pathways. Both minocycline and simvastatin improved fine motor function, but not gross motor or cognitive function. Minocycline modestly decreased lesion size with no effect of simvastatin. At 24 h post-CCI, GOA identified a significant effect of minocycline on chemotaxis, blood circulation, immune response, and cell to cell signaling pathways. Inflammatory pathways were affected by minocycline only at the 72 h time point. There was a minimal effect of simvastatin on gene expression 24 h after injury, with increasing effects at 72 h and 7 days. GOA identified a significant effect of simvastatin on inflammatory response at 72 h and 7 days. In conclusion, treatment with minocycline and simvastatin resulted in significant effects on gene expression in the brain reflecting adequate brain penetration without producing significant neurorestorative effects.

In the present study, we investigated whether the rostral ventrolateral medulla (RVLM), the nucleus tractus solitarius (NTS) and the periaqueductal grey (PAG), regions known to have important cardiovascular regulatory functions, also show increased microglial activation and whether this coincides with increased neuronal activity. We also investigated whether minocycline inhibited microglial activation and whether this also affected neuronal activity and cardiac function. Compared to controls there was a significant increase in the proportion of activated microglia and neuronal activation in the PVN, RVLM, NTS and PAG, 12weeks following myocardial infarction (P<0.001). Intracebroventricular infusion of minocycline (beginning one week prior to infarction) significantly attenuated the increase in microglial activation by at least 50% in the PVN, RVLM, PAG and NTS, and neuronal activation was significantly reduced by 50% in the PVN and virtually abolished in the PAG, RVLM and NTS. Cardiac function (percent fractional shortening) was significantly reduced by 55% following myocardial infarction but this was not ameliorated by minocycline treatment. The results suggest that following myocardial infarction, inflammation occurs in brain nuclei that play key roles in cardiovascular regulation and that attenuation of this inflammation may not be sufficient to ameliorate cardiac function.

    Bloom syndrome (BS) is an inherited genomic instability disorder caused by disruption of the BLM helicase and confers an extreme cancer predisposition. Here we report on a girl with BS who developed acute lymphoblastic leukaemia (ALL) at age nine, and treatment-related acute myeloid leukaemia (t-AML) aged 12. She was compound heterozygous for the novel BLM frameshift deletion c.1624delG and the previously described c.3415C>T nonsense mutation. Two haematological malignancies in a child with BS imply a fundamental role for BLM for normal haematopoiesis, in particular in the presence of genotoxic stress. PMID:24932421

    Microglia, the brain innate immune cells, are activated in response to amyloid beta (Aβ) resulting in neuroinflammation in AD brains. Recently, two phenotypes have been described for microglia: the pro-inflammatory classical and the anti-inflammatory alternative. Changes in microglia phenotype that control their phagocytic function are yet to be determined. The highly neurotoxic Aβ oligomers (oAβ) formed at an early disease stage induce pro-inflammatory microglia activation releasing neurotoxic mediators and contributing to neurodegeneration. A novel strategy for AD treatment is to attenuate microglia-induced inflammation while maintaining efficient Aβ clearance. Minocycline effectively crosses the blood-brain barrier and has widely reported neuroprotective effects. Yet, its exact mechanism of neuroprotection and its effects on microglia are still unknown. The aim of this study is to investigate the effect of minocycline on the phagocytic uptake of fAβ by primary microglia in relation to their activation state in an inflammatory milieu generated by oAβ or LPS. The study shows that minocycline is able to attenuate oAβ-induced neuroinflammatory response of microglia by inhibiting their pro-inflammatory phenotype activation. In addition, a significant enhancement of fAβ phagocytosis by minocycline- treated microglia is reported for the first time, providing novel insight into its neuroprotective role in AD.

    Over 90% of leukemic blasts in patients with acute lymphoblastic leukemia express the marker CD22. Inotuzumab ozogamicin (INO) is a CD22-directed humanized monoclonal antibody conjugated to the potent cytotoxin, calicheamicin, via an acid labile linker. INO has shown high rates of response in the treatment of relapsed and refractory (R/R) ALL in single-agent studies, with fewer adverse effects than traditional cytotoxic chemotherapy. Given this experience, studies are now being done to evaluate INO in combination with low-intensity chemotherapy as frontline treatment for older adults with ALL and patients with R/R disease. Herein we will discuss the use of INO in the treatment of acute lymphoblastic leukemia.

    Acute ischemic stroke is a morbid and disabling medical condition with a significant social and economic impact throughout the world. Intravenous thrombolysis (IVT) has been the first line treatment for patients presenting up to 4.5 hours after symptom onset for many years. Endovascular stroke treatment has been used successfully as rescue therapy after failed IVT; in patients with contraindications to rtPA or presenting outside the 4.5-hour window. The effectiveness of IVT is high for distal thrombi but significantly lower for proximal occlusions. Endovascular treatment has been revolutionized by the evolution from intra-arterial thrombolysis and first generation mechanical devices to the current generation of stent retrievers and aspiration systems with large bore catheters. These devices have been associated with excellent revascularization, improved clinical outcomes, shorter procedure times and reduced device and procedure related complications. We report the current literature, clinical standards and perspectives on mechanical thrombectomy in acute ischemic stroke.

    The proportion of diabetic patients who are hospitalised for stroke has been increasing in recent years, currently reaching almost a third of all cases of stroke. In addition, about half of patients with acute stroke present hyperglycaemia in the first hours of the stroke. Although hyperglycaemia in the acute phase of stroke is associated with a poor prognosis, its treatment is currently a topic of debate. There is no evidence that the adminstration of intravenous insulin to these patients offers benefits in terms of the evolution of the stroke. New studies in development, such as the SHINE study (Stroke Hyperglycemia Insulin Network Effort), may contribute to clarifying the role of intensive control of glycaemia during the acute phase of the stroke. Ultimately, patients who have presented with stroke should be screened for diabetes. PMID:26189890

    How many times have you heard from a patient or groaned yourself "Oh, my aching back?" Innocuous movements such as reaching, stooping, or leaning are halted mid-performance as you sense "something" give, catch, snap, grab, or slide in your lower back. Such subjective complaints may also include sensations of discomfort described as stabbing, sharp, dull, hot/burning, tingling, or numbing. In practice, you will be required to assess these subjective symptoms, effectively document objective data, formulate a diagnosis, and plan appropriate treatment for your patients. Careful attention to history, associated symptoms, and following a systematic approach to back pain can make the rule-in/out differentials less taxing on both the practitioner and the patient.

    Objective The effect of induced hypothermia on severe acute carbon monoxide (CO) poisoning remains to be addressed further. We investigated the effect of induced hypothermia on severe acute CO poisoning. Methods Retrospective chart review was conducted for patients who diagnosed as severe acute CO poisoning in emergency department and underwent induced hypothermia from May 2013 to May 2014. Hospital courses with critical medication and major laboratory results were investigated through the chart review. Results Among total 227 patients with acute CO poisoning during the period of study, patients with severe acute CO poisoning were 15. All patients underwent induced hypothermia with a temperature goal 33°C. Initial and follow-up levels of S100B protein after induced hypothermia were 0.47 μg/L (interquartile range, 0.11 to 0.71) and 0.10 μg/L (interquartile range, 0.06 to 0.37), respectively (P = 0.01). The mean Glasgow Coma Scales at emergency department admission was 6.87 ± 3.36. Except 1 patient who expired after cardiopulmonary resuscitation, Glasgow Coma Scales at 30-day of hospital discharge were 15 in 10 patients (71.4%), 14 in 1 patient (7.1%), 13 in 1 patient (7.1%), and 6 in 2 patients (14.2%). Seven patients (46.7%) developed delayed neurologic sequelae. Four patients showed mild types of delayed neurologic sequelae and 3 showed moderate to severe types of delayed neurologic sequelae. Conclusion Most of patients underwent induced hypothermia had a good recovery from severe acute CO poisoning. Therefore, induced hypothermia may be considered as a possible treatment in severe acute CO poisoning. PMID:27752625

    The comparative susceptibility of 622 recent clinical isolates of anaerobic bacteria to minocycline, doxycycline, and tetracycline was determined by an agar-dilution technique. In addition to Bacteroides fragilis, a variety of other anaerobic bacteria was resistant to achievable blood concentrations of tetracycline (55% inhibited by 6.25 μg/ml) and doxycycline (58% inhibited by 2.5 μg/ml). In contrast, minocycline was significantly more active (P < 0.05) than both doxycycline and tetracycline, and 70% of strains were inhibited by achievable blood concentrations of this antibiotic (2.5 μg/ml). The enhanced activity of minocycline was particularly striking for Peptococcus asaccharolyticus, P. magnus, P. prevotii, Peptostreptococcus anaerobius, and Bacteroides melaninogenicus. Further evaluation of the clinical efficacy of minocycline against anaerobic infections is indicated. PMID:1137358

    Many efforts have been performed in order to understand the role of recruited macrophages in the progression of spinal cord injury (SCI). Different studies revealed a pleiotropic effect played by these cells associated to distinct phenotypes (M1 and M2), showing a predictable spatial and temporal distribution in the injured site after SCI. Differently, the role of activated microglia in injury progression has been poorly investigated, mainly because of the challenges to target and selectively modulate them in situ. A delivery nanovector tool (poly-ε-caprolactone-based nanoparticles) able to selectively treat/target microglia has been developed and used here to clarify the temporal and spatial involvement of the pro-inflammatory response associated to microglial cells in SCI. We show that a treatment with nanoparticles loaded with minocycline, the latter a well-known anti-inflammatory drug, when administered acutely in a SCI mouse model is able to efficiently modulate the resident microglial cells reducing the pro-inflammatory response, maintaining a pro-regenerative milieu and ameliorating the behavioral outcome up to 63 days post injury. Furthermore, by using this selective delivery tool we demonstrate a mechanistic link between early microglia activation and M1 macrophages recruitment to the injured site via CCL2 chemokine, revealing a detrimental contribution of pro-inflammatory macrophages to injury progression after SCI.

    Clinical case reports and prospective trials have demonstrated a reproducible benefit of hypothalamic-pituitary-adrenal (HPA) axis modulation on the rate of recovery from acute inflammatory central nervous system (CNS) demyelination. As a result, corticosteroid preparations and adrenocorticotrophic hormones are the current mainstays of therapy for the treatment of acute optic neuritis (AON) and acute demyelination in multiple sclerosis. Despite facilitating the pace of recovery, HPA axis modulation and corticosteroids have failed to demonstrate long-term benefit on functional recovery. After AON, patients frequently report visual problems, motion perception difficulties and abnormal depth perception despite ‘normal’ (20/20) vision. In light of this disparity, the efficacy of these and other therapies for acute demyelination require re-evaluation using modern, high-precision paraclinical tools capable of monitoring tissue injury. In no arena is this more amenable than AON, where a new array of tools in retinal imaging and electrophysiology has advanced our ability to measure the anatomic and functional consequences of optic nerve injury. As a result, AON provides a unique clinical model for evaluating the treatment response of the derivative elements of acute inflammatory CNS injury: demyelination, axonal injury and neuronal degeneration. In this article, we examine current thinking on the mechanisms of immune injury in AON, discuss novel technologies for the assessment of optic nerve structure and function, and assess current and future treatment modalities. The primary aim is to develop a framework for rigorously evaluating interventions in AON and to assess their ability to preserve tissue architecture, re-establish normal physiology and restore optimal neurological function.

    , minocycline 1h after APAP decreased cell killing by half. In conclusion, release of Fe(2+) from lysosomes followed by uptake into mitochondria via MCFU occurs during APAP hepatotoxicity. Mitochondrial iron then catalyzes toxic hydroxyl radical formation, which triggers the MPT and cell killing. The efficacy of minocycline post-treatment shows minocycline as a possible therapeutic agent against APAP hepatotoxicity. PMID:27345134

    Lymphatic filariasis and onchocerciasis are parasitic helminth diseases, which cause severe morbidities such as elephantiasis, skin disease and blindness, presenting a major public health burden in endemic communities. The anti-Wolbachia consortium (A·WOL: http://www.a-wol.com/) has identified a number of registered antibiotics that target the endosymbiotic bacterium, Wolbachia, delivering macrofilaricidal activity. Here we use pharmacokinetics/pharmacodynamics (PK/PD) analysis to rationally develop an anti-Wolbachia chemotherapy by linking drug exposure to pharmacological effect. We compare the pharmacokinetics and anti-Wolbachia efficacy in a murine Brugia malayi model of minocycline versus doxycycline. Doxycycline exhibits superior PK in comparison to minocycline resulting in a 3-fold greater exposure in SCID mice. Monte-Carlo simulations confirmed that a bi-daily 25–40 mg/Kg regimen is bioequivalent to a clinically effective 100–200 mg/day dose for these tetracyclines. Pharmacodynamic studies showed that minocycline depletes Wolbachia more effectively than doxycycline (99.51% vs. 90.35%) after 28 day 25 mg/Kg bid regimens with a more potent block in microfilarial production. PK/PD analysis predicts that minocycline would be expected to be 1.7 fold more effective than doxycycline in man despite lower exposure in our infection models. Our findings warrant onward clinical investigations to examine the clinical efficacy of minocycline treatment regimens against lymphatic filariasis and onchocerciasis. PMID:26996237

    Recent experimental and clinical reports support the fact that the minocycline exhibits significant neuroprotective activity in neurodegenerative diseases. However, its mechanism of neuroprotection is still far from our understanding. Besides, minocycline does not always produce neuroprotective effect. Therefore, this study has been designed to explore the possible mechanism of minocycline in experimental model of HD in rats. Intrastriatal administration of quinolinic acid caused a significant reduction in body weight, motor dysfunction (impaired locomotor activity, rotarod performance, and beam walk test), oxidative damage (as evidenced by increase in lipid peroxidation, nitrite concentration, and depletion of super oxide dismutase and catalase), increased TNF-α and IL-6 levels as compared to the sham-treated animals. Minocycline (25, 50, and 100 mg/kg) treatment (for 21 days) significantly improved body weight, locomotor activity, rotarod performance, balance beam walk performance, oxidative defense, attenuated TNF-α and IL-6 levels as compared to quinolinic-acid (QA)-treated animals. This study provides evidence that minocycline might have neuroprotective effect against QA-induced Huntington-like behavioral, biochemical alterations, and neuroinflammation in rats. PMID:22392362

    To assess the symptoms and signs of acute otitis media and efficiency of simple antibiotics like amoxicillin in its treatment in the primary health care setup. This is a prospective longitudinal study including 204 patients from different institutions. Patients were diagnosed as suffering from acute otitis media when presented with earache, fever, fullness and or otorrhea. Patients were divided into two equal groups on basis of the treatment they received, Group A received only symptomatic treatment while Group B were given Amoxicillin (40 mg/kg/day) for 7 days. Acute otitis media was common in children under 15 years (64.7%). Patients presented with earache (100%), aural fullness (90.68%), fever (76.47%) associated with recent onset of upper respiratory tract infections (88.23%). In group A, improvement was noticed in 28.43% in 3 days while 35.29% in 7 days. In group B, improvement was noticed in 48.03% in day 3 while 86.27% in day 7. In countries where medical care is scarce, patients lost to follow up, it is wise to treat with simple antibiotics like amoxicillin in adequate dose than to treat only symptomatically. It prevents chronicity, early hearing impairments and reduces antibiotic resistance.

    Depression is a risk factor for morbidity and mortality in patients with coronary heart disease (CHD), especially following acute coronary syndrome (ACS). Evidence from recent clinical trials suggests that treatment-resistant depression may be associated with a particularly high risk of mortality or cardiac morbidity in post-ACS patients. This manuscript reviews this evidence, and considers possible explanations for this relationship. Directions for future research are also considered, with particular emphasis on efforts to elucidate the underlying mechanisms and to develop more efficacious treatments for depression in patients with CHD.

    2007-01-01

    The management of acute episodes in schizophrenia is frequently initiated in the psychiatric emergency department and requires rapid intervention to relieve distress and psychiatric symptoms. Both non-pharmacological and pharmacological interventions are needed to calm the patient and prevent potential harm to the patient or others. Treatment is a step-by-step process including management of behavioral symptomatology, diagnosis of potential organic causes, and evaluation of potential substance abuse. Better care is delivered if predefined standard operating procedures are adopted systematically. The ultimate goal of treatment is to establish a therapeutic alliance with the patient. Atypical antipsychotics given orally are recommended as a first-line treatment. As the treatment endpoint is calmness rather than sleep, a non-sedative antipsychotic agent is usually preferred. Drug tolerance is a major issue for the patient. Amisulpride is an effective atypical antipsychotic agent in this context. The optimal dose is 800 mg/day, which is effective on positive and negative symptoms and can be given from the first day with a low risk of extrapyramidal symptoms. Since drug–drug interactions are limited, agitation and anxiety may be controlled by short-term adjunctive therapy with benzodiazepines. In conclusion, amisulpride is an appropriate first-line treatment for the management of acute psychosis. PMID:18360610

    2006-01-01

    The recently published Clinical Practice Guideline for the Diagnosis and Management of Acute Otitis Media represents a sincere effort by the AAP andthe AAFP to provide management guidelines for the practitioner based upon the best scientific evidence available. Despite many years of research and hundreds of clinical studies addressing various aspects of the epidemiology, clinical presentation, and treatment of acute otitis media, important questions remain unaddressed or have been addressed in a less than optimal fashion. These gaps in knowledge and deficiencies in several of the studies that formed the scientific basis for the proposed guidelines are the major reasons behind continued disagreement over certain recommendations. Until more comprehensive and careful analyses can be performed, disagreements are likely to persist. Even so, there is general agreement about most of the recommendations made in these guidelines, and these recommendations will provide a very valuable framework for the practicing physician as he or she cares for children with acute otitis media. To briefly review the major points, first is the critical importance of accurately diagnosing acute otitis media using a combination of clinical findings and observable abnormalities of the tympanic membrane and middle ear space. Particularly important is the differentiation of acute otitis media from otitis media with effusion. Second is the value of treating the pain associated with acute otitis media as a regular component of care, irrespective of any decision concerning antimicrobial treatment. Third is the option, for a select group of older patients with nonsevere disease, of withholding antimicrobial therapy for the first 48 to 72 hours, if close follow-up and active parental involvement can be guaranteed. Fourth is the recommendation that if an antimicrobial agent is used, high-dose amoxicillin (80 to 90 mg/kg/d) is the treatment of choice for most children at the time of initial presentation

    This study had been performed to investigate the anatomic and functional outcomes of nepafenac 0.1% therapy in acute central serous chorioretinopathy (CSC). The medical records of 30 patients with acute CSC were reviewed for a total of 31 eye charts. Seventeen eye records of 16 patients who were treated with topical nepafenac 0.1% three times daily for four weeks and continued until complete resolution of subretinal fluid were appraised. Fourteen patients with acute CSC (a total of 14 eye records) who did not receive treatment served as the control group also had been recorded. The proportion of eyes with complete resolution of subretinal fluid, serial changes in the mean best corrected visual acuity (BCVA), and the mean central foveal thickness (CFT) at 6 months of therapy were the outcomes measured. Mean age was 42.6±8.2 years in the treatment group and 41.1±7.1 years in the control group (p=0.85). At 6 months, 14 eyes (82.3%) in the treatment group and 6 eyes (42.8%) in the control group revealed a complete resolution in the subretinal fluid (p=0.02). In the treatment group, mean BCVA (LogMAR) significantly improved from 0.19±0.17 at baseline to 0.09±0.12 at 6 months (p=0.01). In the control group, mean BCVA (LogMAR) was 0.13±0.14 at baseline and decreased to 0.1±0.11 at 6 months (p=0.28). In the treatment group, mean CFT was 349±115 µm at baseline and significantly improved to 221±95 µm at 6 months (p<0.01). In the control group, mean CFT declined from 391±138 µm at baseline to 301±125 µm at 6 months (p=0.06). No treatment-related ocular or systemic side effects were observed. In conclusion, nepafenac 0.1% has the potential to treatment acute CSC. Further trials are warranted to study its safety and efficacy for this disease. PMID:24822228

    Dosing protocol and analgesic efficacy have been proposed to be important determinants of the magnitude of opioid tolerance. The present study examined the effect of acute, intermittent and continuous treatment with the low analgesic efficacy agonist morphine on analgesic tolerance. Mice were implanted s.c. with a 25 mg morphine pellet for 1-7 days. Other mice were implanted s.c. with two 25 mg, or one 75 mg morphine pellet for 7 days. The release of morphine from subcutaneous implanted pellets was quantitated using a spectrophotometric assay. In other studies, mice were injected with morphine once (18.5-185 mg/kg/day; approximately 10-100 times ED(50) for morphine analgesia) or once/day for 7 days. Controls were implanted with a placebo pellet or injected with saline. Analysis of drug release from a 25 mg pellet indicated that release was greatest during the first 24 h, declined and then remained relatively constant. The amount of morphine released over 7 days by a 75 mg pellet (23.9 mg) was more than that of a single 25 mg pellet (15.4 mg) but less than two 25 mg pellets (30.8 mg). Following treatment, morphine cumulative dose-response studies were conducted (tail flick). Continuous treatment with morphine using pellet implantation produced a dose-dependent shift in the morphine ED(50) by 3.3, 5.8 and 8.5 fold for one 25 mg pellet, one 75 mg pellet and two 25 mg pellets, respectively. Acute and intermittent morphine administration produced substantially less analgesic tolerance than continuous release of morphine by implant pellets. The maximum shift in the ED(50) was 1.6 for acute treatment and 2.7 for 7 day intermittent treatment; despite a larger total daily dose. The present results indicate that continuous treatment with morphine results in greater analgesic tolerance than acute or intermittent morphine treatment even at comparable daily doses. These results are consistent with the suggestion that intermittent dosing has reduced risk of producing opioid

    Background: The orbital complications account for about 80% of all complications secondary to acute rhinosinusitis. If the treatment is not correct and in time, orbital complications could progress rapidly, leading to optic neuritis, cavernous sinus thrombophlebitis or life-threatening intracranial complications. Aims: To evaluate the therapeutic efficacy of conservative therapy for the patients with orbital cellulitis and endoscopic sinus surgery (ESS) performed on patients with subperiosteal abscess (SPA) secondary to acute rhinosinusitis in children. Study Design: Retrospective cross-sectional study. Methods: The retrospective study included 31 pediatric patients with orbital complications secondary to acute rhinosinusitis. In all cases, intensive treatment was initiated with a combination of oral or intravenous antibiotics, glucocorticoid and gelomyrtol forte after admission. ESS was performed if an improvement in the condition of patients did not occur after 48 hours. However, the patients with orbital SPA, motility disorders of eyeball or decreased vision received ESS immediately within 24 hours. Results: Sixteen patients were cured by conservative therapy and 15 patients by ESS. All of the signs and symptoms disappeared after conservative therapy or ESS. There were no recurrences within the follow-up period of 1 to 8 years. Conclusion: Conservative therapy is an effective method for patients with inflammatory edema and most cases of orbital cellulitis in children. SPA can be cured by ESS.

If the treatment is not correct and in time, orbital complications could progress rapidly, leading to optic neuritis, cavernous sinus thrombophlebitis or life-threatening intracranial complications. Aims: To evaluate the therapeutic efficacy of conservative therapy for the patients with orbital cellulitis and endoscopic sinus surgery (ESS) performed on patients with subperiosteal abscess (SPA) secondary to acute rhinosinusitis in children. Study Design: Retrospective cross-sectional study. Methods: The retrospective study included 31 pediatric patients with orbital complications secondary to acute rhinosinusitis. In all cases, intensive treatment was initiated with a combination of oral or intravenous antibiotics, glucocorticoid and gelomyrtol forte after admission. ESS was performed if an improvement in the condition of patients did not occur after 48 hours. However, the patients with orbital SPA, motility disorders of eyeball or decreased vision received ESS immediately within 24 hours. Results: Sixteen patients were cured by conservative therapy and 15 patients by ESS. All of the signs and symptoms disappeared after conservative therapy or ESS. There were no recurrences within the follow-up period of 1 to 8 years. Conclusion: Conservative therapy is an effective method for patients with inflammatory edema and most cases of orbital cellulitis in children. SPA can be cured by ESS. PMID:27606135

    Clinical experience with hydroxocobalamin in acute cyanide poisoning via ingestion remains limited. This case concerns a 35-year-old mentally ill woman who consumed more than 20 apricot kernels. Published literature suggests each kernel would have contained cyanide concentrations ranging from 0.122 to 4.09 mg/g (average 2.92 mg/g). On arrival, the woman appeared asymptomatic with a raised pulse rate and slight metabolic acidosis. Forty minutes after admission (approximately 70 min postingestion), the patient experienced headache, nausea and dyspnoea, and was hypotensive, hypoxic and tachypnoeic. Following treatment with amyl nitrite and sodium thiosulphate, her methaemoglobin level was 10%. This prompted the administration of oxygen, which evoked a slight improvement in her vital signs. Hydroxocobalamin was then administered. After 24 h, she was completely asymptomatic with normalised blood pressure and other haemodynamic parameters. This case reinforces the safety and effectiveness of hydroxocobalamin in acute cyanide poisoning by ingestion.

    Background. The objectives of this study were to estimate the incidence and evaluate risk factors for development of minocycline-induced cutaneous hyperpigmentation in patients with orthopedic infections. Methods. Patients with orthopedic infections evaluated at Mayo Clinic (Rochester, MN) and treated with minocycline from 1 January 2002 to 31 December 2011 were retrospectively identified. Long-term minocycline suppression was defined as daily minocycline use for at least 3 months. A proportional hazards model was used to evaluate potential risk factors. Results. Of 291 patients receiving long-term minocycline suppression, 54% (156 of 291) developed hyperpigmentation after a mean follow-up of 4.8 years (range, 0.3–13.2 years); 88% involved blue-gray pigmentation of normal skin that appeared most commonly in the lower (75%) and upper extremities (44%). The mean duration of minocycline therapy before hyperpigmentation was 1.5 years (range, 0.1–9 years) with a mean cumulative dosage of 107.3 g (range, 8.6–657 g). Notable risk factors include a history of vitamin D deficiency (relative risk [RR], 6.29; 95% confidence interval [CI], 1.91–15.27; P = .0052), presence of a shoulder prosthesis (RR, 3.2; 95% CI, 1.23–6.56; P = .0062), noncirrhotic liver pathology (RR, 3.63; 95% CI, 1.11–8.75; P = .0359), and use of a concurrent medication also known to cause hyperpigmentation (RR, 4.75; 95% CI, 1.83–10.1; P = .0029). Conclusions. Hyperpigmentation associated with the use of long-term minocycline suppression in patients with orthopedic infections is common. PMID:26835479

  10. Emerging therapies for treatment of acute lung injury and acute respiratory distress syndrome.

    2007-09-01

    Acute lung injury/acute respiratory distress syndrome (ALI/ARDS) is a life-threatening form of respiratory failure that affects a heterogeneous population of critically ill patients. Although overall mortality appears to be decreasing in recent years due to improvements in supportive care, there are presently no proven, effective pharmacological therapies to treat ARDS and prevent its associated complications. The most common cause of death in ARDS is not hypoxemia or pulmonary failure, but rather multiple organ dysfunction syndrome (MODS), suggesting that improving survival in patients with ARDS may be linked to decreasing the incidence or severity of MODS. The key to developing novel treatments depends, in part, on identifying and understanding the mechanisms by which ARDS leads to MODS, although the heterogeneity and complexity of this disorder certainly poses a challenge to investigators. Novel therapies in development for treatment of ALI/ARDS include exogenous surfactant, therapies aimed at modulating neutrophil activity, such as prostaglandin and complement inhibitors, and treatments targeting earlier resolution of ARDS, such as beta-agonists and granulocyte macrophage colony-stimulating factor. From a clinical perspective, identifying subpopulations of patients most likely to benefit from a particular therapy and recognising the appropriate stage of illness in which to initiate treatment could potentially lead to better outcomes in the short term.

    In the world, hereditary angioedema (HAE) affects 1 every 50000 persons. It is characterized by highly disabling and recurrent episodes of cutaneous, abdominal and laryngeal episodes of angioedema. Asphyxia related mortality ranges from 15 to 50%. In Argentina a plasma derived C1 inhibitor concentrate (pdC1INH) has been available for the treatment of acute attacks for many decades, however, only15 (26%) out of 58 patients had received pdC1INH at least once until 2008, and only2 (3.4%) had used it regularly. After worldwide approval of the new drugs for the treatment of acute HAE attacks, adding icatibant to pdC1INH in Argentina, and after publication of the therapeutic guide for the country, 42 (82%) out of 51 patients from the original group has pdC1INH available to treat their next attack. However, 16 (18%) patients continue without access to medication and other 15 (35.7%) obtain their therapy spuriously through some other affected relative in their environment. Only 12 (28.6%) patients of the group self-treated at home. Access to treatment has greatly improved, but needs to be extended to all patients and self-treatment at home should be encouraged.

    Although intravenous administration of tissue plasminogen activator is the only proven treatment after acute ischemic stroke, there is always a concern of hemorrhagic risk after thrombolysis. Therefore, selection of patients with potential benefits in overcoming potential harms of thrombolysis is of great importance. Despite the practical issues in using magnetic resonance imaging (MRI) for acute stroke treatment, multimodal MRI can provide useful information for accurate diagnosis of stroke, evaluation of the risks and benefits of thrombolysis, and prediction of outcomes. For example, the high sensitivity and specificity of diffusion-weighted image (DWI) can help distinguish acute ischemic stroke from stroke-mimics. Additionally, the lesion mismatch between perfusion-weighted image (PWI) and DWI is thought to represent potential salvageable tissue by reperfusion therapy. However, the optimal threshold to discriminate between benign oligemic areas and the penumbra is still debatable. Signal changes of fluid-attenuated inversion recovery image within DWI lesions may be a surrogate marker for ischemic lesion age and might indicate risks of hemorrhage after thrombolysis. Clot sign on gradient echo image may reflect the nature of clot, and their location, length and morphology may provide predictive information on recanalization by reperfusion therapy. However, previous clinical trials which solely or mainly relied on perfusion-diffusion mismatch for patient selection, failed to show benefits of MRI-based thrombolysis. Therefore, understanding the clinical implication of various useful MRI findings and comprehensively incorporating those variables into therapeutic decision-making may be a more reasonable approach for expanding the indication of acute stroke thrombolysis.

    Objectives: We report the pathophysiology and treatment results of type A acute aortic dissection from our 20-year experience. Methods: We studied 673 patients with type A acute aortic dissection who underwent initial treatment from 1994 through July 2014. We divided these patients into two groups. The former group comprised 448 patients from 1994 through 2008, and the latter group comprised 225 patients from 2009 onward, when the current strategy of initial treatment and surgical technique including the early organ reperfusion therapies were established. Results: Women were significantly often presented than men in patients over 60 years of age. Thrombosed-type dissection accounted for more than half in patients over 70 years, and significantly often complicated pericardial effusion and cardiac tamponade than patent type. Malperfusion occurred in 26% of patients. Central repair operations were performed in 579 patients. In-hospital mortality for all patients was 15%, and for the patients who underwent central repair operations was 10%. Former period of operation, malperfusion, and preoperative cardiopulmonary arrest were significant risk factor of in-hospital death. Preoperative left main trunk (LMT) stents were placed in eight patients and superior mesenteric artery (SMA) intervention was performed in five, they were effective to improve the outcome. From 2009 onward, in-hospital mortality was 5.0% and there was no significant risk factor. Conclusion: Surgical results of type A acute aortic dissection were dramatically improved in the past 20 years. Early reperfusion strategy for the patients with malperfusion improved the outcomes.

  14. Treatment of acute non-anion gap metabolic acidosis.

    PubMed

    Kraut, Jeffrey A; Kurtz, Ira

    2015-02-01

    Acute non-anion gap metabolic acidosis, also termed hyperchloremic acidosis, is frequently detected in seriously ill patients. The most common mechanisms leading to this acid-base disorder include loss of large quantities of base secondary to diarrhea and administration of large quantities of chloride-containing solutions in the treatment of hypovolemia and various shock states. The resultant acidic milieu can cause cellular dysfunction and contribute to poor clinical outcomes. The associated change in the chloride concentration in the distal tubule lumen might also play a role in reducing the glomerular filtration rate. Administration of base is often recommended for the treatment of acute non-anion gap acidosis. Importantly, the blood pH and/or serum bicarbonate concentration to guide the initiation of treatment has not been established for this type of metabolic acidosis; and most clinicians use guidelines derived from studies of high anion gap metabolic acidosis. Therapeutic complications resulting from base administration such as volume overload, exacerbation of hypertension and reduction in ionized calcium are likely to be as common as with high anion gap metabolic acidosis. On the other hand, exacerbation of intracellular acidosis due to the excessive generation of carbon dioxide might be less frequent than in high anion gap metabolic acidosis because of better tissue perfusion and the ability to eliminate carbon dioxide. Further basic and clinical research is needed to facilitate development of evidence-based guidelines for therapy of this important and increasingly common acid-base disorder.

    Acute appendicitis (AA) is among the most common cause of acute abdominal pain. Diagnosis of AA is challenging; a variable combination of clinical signs and symptoms has been used together with laboratory findings in several scoring systems proposed for suggesting the probability of AA and the possible subsequent management pathway. The role of imaging in the diagnosis of AA is still debated, with variable use of US, CT and MRI in different settings worldwide. Up to date, comprehensive clinical guidelines for diagnosis and management of AA have never been issued. In July 2015, during the 3rd World Congress of the WSES, held in Jerusalem (Israel), a panel of experts including an Organizational Committee and Scientific Committee and Scientific Secretariat, participated to a Consensus Conference where eight panelists presented a number of statements developed for each of the eight main questions about diagnosis and management of AA. The statements were then voted, eventually modified and finally approved by the participants to The Consensus Conference and lately by the board of co-authors. The current paper is reporting the definitive Guidelines Statements on each of the following topics: 1) Diagnostic efficiency of clinical scoring systems, 2) Role of Imaging, 3) Non-operative treatment for uncomplicated appendicitis, 4) Timing of appendectomy and in-hospital delay, 5) Surgical treatment 6) Scoring systems for intra-operative grading of appendicitis and their clinical usefulness 7) Non-surgical treatment for complicated appendicitis: abscess or phlegmon 8) Pre-operative and post-operative antibiotics.

    Berlin-Frankfurt-Munster (BFM) and Dana-Farber Cancer Institute (DFCI) consortia's treatment strategies for acute lymphoblastic leukaemia (ALL) in children are widely used. We compared the health effects and monetary costs of hospital treatments for these two strategies. Parents of children treated at seven centres in Canada, Italy and the USA completed health-related quality of life (HRQL) assessments during four active treatment phases and at 2 years after treatment. Mean HRQL scores were used to calculate quality-adjusted life years (QALYs) for a period of 5 years following diagnosis. Total costs of treatment were determined from variables in administrative databases in a universally accessible and publicly funded healthcare system. Valid HRQL assessments (n = 1200) were collected for 307 BFM and 317 DFCI patients, with costs measured for 66 BFM and 28 DFCI patients. QALYs per patient were <1.0% greater for BFM than DFCI. Median HRQL scores revealed no difference in QALYs. The difference in mean total costs for BFM (US$88 480) and DFCI (US$93 026) was not significant (P = 0.600). This study provides no evidence of superiority for one treatment strategy over the other. Current BFM or DFCI strategies should represent conventional management for the next economic evaluation of treatments for ALL in childhood. PMID:24393150

  17. Acute treatment of migraine and the role of triptans.

    2001-03-01

    The use of triptans has improved the ability to treat migraine successfully compared with older treatments. Speed of relief, consistency of effect, and good tolerability have been the hallmarks of these agents. All of the currently available triptans have comparable efficacy and tolerability. Variables between the agents may lead to one agent or dose form being preferred over another in various clinical scenarios. The triptans that are forthcoming may improve on these options through enhanced efficacy rates, tolerability, and headache recurrence rates. There exist increasing options for migraine treatment that may further improve the clinical effects of the older and newer triptans through early treatment of migraine at the stages of mild migraine pain, or even during the prodromal phase of the attack. Additionally, recent work suggests that mini-prophylaxis of migraine at the menses is a highly successful treatment option with the triptans. In this age of managed care, providing cost-effective treatment of headache will take on increasing importance. Techniques such as stratification of acute treatments may enhance cost-effective care, whereas ready availability of the triptans may lead to significant improvements in utilization of parameters such as office visits, emergency room treatment, and even hospitalization.

    Many studies have shown that minocycline, an antibacterial tetracycline, suppresses experimental pain. While minocycline's positive effects on pain resolution suggest that clinical use of such drugs may prove beneficial, minocycline's antibiotic actions and divalent cation (Ca(2+); Mg(2+)) chelating effects detract from its potential utility. Thus, we tested the antiallodynic effect induced by a non-antibacterial, non-chelating minocycline derivative in a model of neuropathic pain and performed an initial investigation of its anti-inflammatory effects in vitro. Intraperitoneal minocycline (100mg/kg) and 12S-hydroxy-1,12-pyrazolinominocycline (PMIN; 23.75 mg/kg, 47.50mg/kg or 95.00 mg/kg) reduce the mechanical allodynia induced by chronic constriction injury of mouse sciatic nerve. PMIN reduces the LPS-induced production of PGE2 by primary microglial cell cultures. Human embryonic kidney cells were transfected to express human toll-like receptors 2 and 4, and the signaling via both receptors stimulated with PAM3CSK4 or LPS (respectively) was affected either by minocycline or PMIN. Importantly, these treatments did not affect the cell viability, as assessed by MTT test. Altogether, these results reinforce the evidence that the anti-inflammatory and experimental pain suppressive effects induced by tetracyclines are neither necessarily linked to antibacterial nor to Ca(2+) chelating activities. This study supports the evaluation of the potential usefulness of PMIN in the management of neuropathic pain, as its lack of antibacterial and Ca(2+) chelating activities might confer greater safety over conventional tetracyclines.

  19. Morphine in the treatment of acute pulmonary oedema--Why?

    PubMed

    Ellingsrud, C; Agewall, S

    2016-01-01

    Morphine has for a long time, been used in patients with acute pulmonary oedema due to its anticipated anxiolytic and vasodilatory properties, however a discussion about the benefits and risks has been raised recently. A literature search in Medline and Embase using the keywords "pulmonary oedema" OR "lung oedema" OR "acute heart failure" AND "morphine" was performed. A certain vasodilation has been described after morphine administration, but the evidence for this mechanism is relatively poor and morphine-induced anxiolysis may possibly be the most important factor of morphine in pulmonary oedema and therefore some authors have suggested benzodiazepines as an alternative treatment. Respiratory depression seems to be a less relevant clinical problem according to the literature, whereas vomiting is common, which may cause aspiration. In the largest outcome study, based on the ADHERE registry, morphine given in acute decompensated heart failure was an independent predictor of increased hospital mortality, with an odds ratio of 4.8 (95% CI: 4.52-5.18, p<0.001). Other, smaller studies have shown a significant association between morphine administration and mortality, which was lost after adjusting for confounding factors. Morphine is still used for pulmonary oedema in spite of poor scientific background data. A randomised, controlled study is necessary in order to determine the effect--and especially the risk--when using morphine for pulmonary oedema. Since the positive effects are not sufficiently documented, and since the risk for increased mortality cannot be ruled out, one can advocate that the use should be avoided.

    PURPOSE Acute thoracic aortic syndrome (ATAS) is a novel term to define emergency aortic conditions with common clinical features and challenges. Traditional management of ATAS includes surgical replacement of the aorta and is correlated with high perioperative mortality and morbidity. We aimed to evaluate our experience and outcomes in patients presenting with ATAS, managed by endovascular techniques. METHODS This cohort consisted of 31 consecutive patients (24 males; mean age, 57.5±13.81 years; range, 19–84 years) with acute thoracic aortic pathologies who underwent endovascular repair between January 2011 and January 2015. The study was designed as a retrospective analysis of prospectively maintained data. RESULTS Complicated acute type-B aortic dissection was the most common pathology (35.5%). All aortic stent-grafts (n=37) and dissection stents (n=9) were implanted with 100% procedural success. The overall in-hospital mortality was 9.7%. The mean follow-up duration of patients who were alive at 30 days was 25.9±11.49 months (3–53 months). So far, there have been no late deaths after 30 days. CONCLUSION In the high-risk setting of ATAS, endovascular procedures come forward as novel therapeutic strategies with promising results. Endovascular repair of ATAS can be considered as a first-line treatment alternative under emergency conditions with encouraging results, particularly when conventional surgical repair cannot be implemented due to prohibitive comorbidities.

    2012-02-15

    Acute low back pain is one of the most common reasons for adults to see a family physician. Although most patients recover quickly with minimal treatment, proper evaluation is imperative to identify rare cases of serious underlying pathology. Certain red flags should prompt aggressive treatment or referral to a spine specialist, whereas others are less concerning. Serious red flags include significant trauma related to age (i.e., injury related to a fall from a height or motor vehicle crash in a young patient, or from a minor fall or heavy lifting in a patient with osteoporosis or possible osteoporosis), major or progressive motor or sensory deficit, new-onset bowel or bladder incontinence or urinary retention, loss of anal sphincter tone, saddle anesthesia, history of cancer metastatic to bone, and suspected spinal infection. Without clinical signs of serious pathology, diagnostic imaging and laboratory testing often are not required. Although there are numerous treatments for nonspecific acute low back pain, most have little evidence of benefit. Patient education and medications such as nonsteroidal anti-inflammatory drugs, acetaminophen, and muscle relaxants are beneficial. Bed rest should be avoided if possible. Exercises directed by a physical therapist, such as the McKenzie method and spine stabilization exercises, may decrease recurrent pain and need for health care services. Spinal manipulation and chiropractic techniques are no more effective than established medical treatments, and adding them to established treatments does not improve outcomes. No substantial benefit has been shown with oral steroids, acupuncture, massage, traction, lumbar supports, or regular exercise programs. PMID:22335313

    It has been demonstrated that spinal microglial activation is involved in formalin-induced pain and that minocycline, an inhibitor of microglial activation, attenuate behavioral hypersensitivity in neuropathic pain models. We investigated whether minocycline could have any anti-nociceptive effect on inflammatory pain, after intraperitonial administration of minocycline, 1 h before formalin (5%, 50 microl) injection into the plantar surface of rat hindpaw. Minocycline (15, 30, and 45 mg/kg) significantly decreased formalin-induced nociceptive behavior during phase II, but not during phase I. The enhancement in the number of c-Fos-positive cells in the L4-5 spinal dorsal horn (DH) and the magnitude of paw edema induced by formalin injection during phase II were significantly reduced by minocycline. Minocycline inhibited synaptic currents of substantia gelatinosa (SG) neurons in the spinal DH, whereas membrane electrical properties of dorsal root ganglion neurons were not affected by minocycline. Analysis with OX-42 antibody revealed the inhibitory effect of minocycline on microglial activation 3 days after formalin injection. These results demonstrate the anti-nociceptive effect of minocycline on formalin-induced inflammatory pain. In addition to the well-known inhibitory action of minocycline on microglial activation, the anti-edematous action in peripheral tissue, as well as the inhibition of synaptic transmission in SG neurons, is likely to be associated with the anti-nociceptive effect of minocycline.

    Minocycline has been proposed as a way to blunt neurovascular injury from matrix metalloproteinases (MMPs) during stroke. However, recent clinical trials suggest that high levels of minocycline may have deleterious side-effects. Here, we showed that very high minocycline concentrations damage endothelial cells via calpain/caspase pathways. To alleviate this potential cytotoxicity, we encapsulated minocycline in liposomes. Low concentrations of minocycline could not reduce tumor necrosis factor α (TNFα)-induced MMP-9 release from endothelial cells. But low concentrations of minocycline-loaded liposomes significantly reduced TNFα-induced MMP-9 release. This study provides proof-of-concept that liposomes may be used to deliver lower levels of minocycline for targeting MMPs in cerebral endothelium. PMID:22491155

    This article reports the treatment of a patient suffered from acute radiation burn covering 41% TBSA, with deep partial-thickness and full-thickness injury, produced by exposure to a large-scale industrial electron accelerator. An open wound began to appear and enlarged gradually 10 weeks after the exposure. Serious wound infection with methicillin-resistant Staphylococcus aureus and Pseudomonas aeruginosa, pneumonia, respiratory failure, systemic inflammatory response syndrome, nephropathy and hypoproteinemia developed successively since 3 weeks after the wound formation. Skin grafts failed to survive, resulting in enlargement of the wound. After being treated with proper measures, including parenteral nutrition, respiratory support with a ventilator, appropriate antibiotics, steroid administration for nephropathy, deep debridement for wounds followed by skin grafting, the patient was cured and discharged after undergoing 15 operations in 500 days. The clinical condition of an extensive acute radiation burn is complicated. We should pay close attention to the changes in functions of organs, and strengthen the therapeutic strategies to support the function of organs to reduce the incidence of systemic complications. The control of the infection and the timely and effective repair of the wound are still the key points of the treatment of an extensive local radiation injury.

    First introduced into clinical practice in 1969, glibenclamide (US adopted name, glyburide) is known best for its use in the treatment of diabetes mellitus type 2, where it is used to promote the release of insulin by blocking pancreatic KATP [sulfonylurea receptor 1 (Sur1)-Kir6.2] channels. During the last decade, glibenclamide has received renewed attention due to its pleiotropic protective effects in acute CNS injury. Acting via inhibition of the recently characterized Sur1-Trpm4 channel (formerly, the Sur1-regulated NCCa-ATP channel) and, in some cases, via brain KATP channels, glibenclamide has been shown to be beneficial in several clinically relevant rodent models of ischemic and hemorrhagic stroke, traumatic brain injury, spinal cord injury, neonatal encephalopathy of prematurity, and metastatic brain tumor. Glibenclamide acts on microvessels to reduce edema formation and secondary hemorrhage, it inhibits necrotic cell death, it exerts potent anti-inflammatory effects and it promotes neurogenesis—all via inhibition of Sur1. Two clinical trials, one in TBI and one in stroke, currently are underway. These recent findings, which implicate Sur1 in a number of acute pathological conditions involving the CNS, present new opportunities to use glibenclamide, a well-known, safe pharmaceutical agent, for medical conditions that heretofore had few or no treatment options.

    Monoclonal antibodies have become an important treatment modality in cancer therapy. Genetically engineered chimaeric and humanised antibodies have demonstrated activity against a variety of tumours. Whereas the humanised anti-CD33 monoclonal antibody HuM195 has only modest activity against overt acute myeloid leukaemia (AML), it can eliminate minimal residual disease detectable by reverse transcription-polymerase chain reaction in acute promyelocytic leukaemia. High-dose radioimmunotherapy with beta-particle-emitting isotopes targeting CD33, CD45 and CD66 can potentially allow intensification of antileukaemic therapy before bone marrow transplantation. Conversely, alpha-particle immunotherapy with isotopes such as bismuth-213 or actinium-225 offers the possibility of selective tumour cell kill while sparing surrounding normal cells. Targeted chemotherapy with the anti-CD33-calicheamicin construct gemtuzumab ozogamicin has produced remissions as a single agent in patients with relapsed AML and appears promising when used in combination with standard chemotherapy in the treatment of newly diagnosed AML.

    In the USA and internationally, women experience farranging differences with respect to acute coronary syndrome (ACS) and myocardial infarction (MI). Women suffer from more comorbidities than men, such as smoking, obesity, hypertension, diabetes, and poor mental health. They some-times exhibit atypical MI presentation symptoms and are overall less likely to present with chest pain. Women are more likely than men to encounter delays between the onset of symptoms and arrival at the hospital or to guideline treatment. The use of various surgical and pharmacological treatments, including revascularization approaches, also differs. Women, on average, have worse outcomes than men following MI, with more complications, higher mortality rates, and poorer recovery. Internationally, outcomes are similar despite various differences in health care and culture in non-US countries. In this review, we detail differences regarding ACS and MI in women, describing their complex correlations and discussing their possible causes. Educational approaches that are tailored to women might help to reduce the incidence of ACS and MI, as well as outcomes following hospitalization. Although outcomes following acute MI have been improving over the years, women may require special consideration in order to see continued improvement.

    Migraine is a common disease in children and adolescents. The incidence of migraine has increased alarmingly in the general population during recent decades. Migraine causes considerable individual suffering and impaired quality of life. Therefore, appropriate management is essential. In this article, the treatment of acute migraine in children and adolescents will be reviewed. Only a few randomized controlled studies have been published and high placebo rates are a major problem for proving superiority of active drugs. Generally, acetaminophen (paracetamol) and ibuprofen are accepted as drugs of first choice, even though the evidence is poor for the former and limited for latter. Among 14 studies on triptans in adolescents, 9 showed some superiority over placebo with respect to pain relief and pain freedom, and among 6 studies in children, 5 suggest some superiority over placebo. Sumatriptan nasal spray and zolmitriptan nasal spray have been approved for adolescents in Europe; almotriptan has been approved for adolescents in the USA, as has rizatriptan for patients aged 6-17 years. A recent study demonstrated the efficacy of a fixed combination of sumatriptan and naproxen in adolescents with migraine. In conclusion, evidence for the pharmacological treatment of acute migraine in children is very poor and evidence for adolescents is better but still limited. PMID:23575981

    To evaluate the clinical efficacy and safety of Qinghouyan lozenge in the treatment of acute pharyngitis due to Lung-heat and Yin-deficiency, and compare with Qinghouyan oral Liquid. Totally 144 subjects were enrolled and randomly divided into two groups (72 in the test group and 72 in the control group). The participants in the test group were given Qinghouyan lozenge for 5 days, and those in the control group were given Qinghouyan oral Liquid for 5 days. The effectiveness evaluation indexes were pharyngalgia/odynophagia disappearance rate, overall efficacy of TCM syndromes, TCM syndrome scores, and single syndrome and sign disappearance rate. During the test, the safety was evaluated by vital sign, lab examination indexes and adverse events. The results for the full analysis set showed that the couth disappearance rate, the incidence rate of TCM syndromes, and the throat/uvula congestion disappearance rate of the test group were higher than that of the control group (P < 0.05), with significant differences in the changes in syndrome scores between the two groups (P < 0.05). Altogether 3 adverse events were observed in the test group while 6 adverse events in the control group, without significant differences in the adverse event rate between the two groups (P < 0.05), serious abnormal laboratory examinations and vital signs. In conclusion, Qinghouyan lozenge has better efficacy in treatment of acute pharyngitis due to Lung-heat and Yin-deficiency than Qinghouyan oral liquid, with good safety. PMID:26080572

    A review of the evidence on treatment of acute bronchiolitis is presented. There is sufficient evidence on the lack of effectiveness of most interventions tested in bronchiolitis. Apart from oxygen therapy, fluid therapy, aspiration of secretions and ventilation support, few treatment options will be beneficial. There are doubts about the efficacy of inhaled bronchodilators (salbutamol or adrenaline), with or without hypertonic saline solution, suggesting that these options should be selectively used as therapeutic trials in moderate-severe bronchiolitis. Heliox and non-invasive ventilation techniques, methylxanthine could be used in cases with respiratory failure, in patients with apnea, and surfactant and inhaled ribavirin in intubated critically ill patients. The available evidence does not recommend the use of oral salbutamol, subcutaneous adrenaline, anticholinergic drugs, inhaled or systemic corticosteroids, antibiotics, aerosolized o intravenous immunoglobulin, respiratory physiotherapy and others (nitric oxide, recombinant human deoxyribonuclease, recombinant interferon, nebulised furosemide and so on).

    We present an interesting case of salicylism arising from the use of methyl salicylate as part of a herbal skin cream for the treatment of psoriasis. A 40-year-old man became quite suddenly and acutely unwell after receiving treatment from an unregistered naturopath. Methyl salicylate (Oil of Wintergreen) is widely available in many over the counter topical analgesic preparations and Chinese medicated oils. Transcutaneous absorption of the methyl salicylate was enhanced in this case due to the abnormal areas of skin and use of an occlusive dressing. The presence of tinnitus, vomiting, tachypnoea and typical acid/base disturbance allowed a diagnosis of salicylate toxicity to be made. Our patient had decontaminated his skin prior to presentation, limiting the extent of toxicity and was successfully treated with rehydration and establishment of good urine flow.

    The molecular analysis of acute lymphoblastic leukemia (ALL) has provided exciting insights into the pathogenesis of this disease. This disease is heterogenous and can be subtyped based on chromosomal, immunophenotypic, and structural criteria. The varying prognostic implications of different ALL subtypes markedly influence the treatment decisions in adults. Many patients with T-cell ALL can be cured with chemotherapy alone. In contrast, patients with early B-lineage ALL with certain chromosomal abnormalities, especially the Philadelphia chromosome, do not have durable responses to chemotherapy and should receive a bone marrow transplantation if an HLA-matched donor is available. Recent reports have shown improved results for adults with B-cell ALL (Burkitt's) after intensive alternating cycles of chemotherapy containing high doses of methotrexate and cyclophosphamide. Future clinical and laboratory investigation should lead to the development of novel and possibly more effective treatments specifically tailored for different subsets of ALL. PMID:8775728

    Although survival rates for acute lymphocytic leukemia (ALL), especially in children, have shown dramatic improvement over time, poor outcomes are still observed in patients who have refractory or relapsed disease after conventional chemotherapy. New therapeutic options are urgently needed. Bortezomib (Velcade, formerly PS-341) is the first proteasome inhibitor approved by the US FDA for the treatment of newly diagnosed multiple myeloma and relapsed/refractory multiple myeloma and mantle cell lymphoma. Although the mechanisms of bortezomib anticancer activity are still not completely understood, it is a new treatment option for patients with refractory or relapsed ALL, particularly when used in combination with conventional chemotherapy or targeted agents. This review summarizes recent advancements in the understanding of the bortezomib molecular mechanism of action in ALL. Understanding of the molecular approaches might help customize cancer chemotherapy for each individual patient, directing the field towards rational therapeutics.

    2007-04-01

    Acute otitis media (AOM) is both a commonly diagnosed condition and a frequent indication for antibiotic use in children. Recent literature suggests that antibiotics are not needed in many children with AOM, as most cases resolve spontaneously without complication. However, a majority of AOM infections in children are still treated with antibiotics. The American Academy of Pediatrics and American Academy of Family Physicians released a guideline for treatment of AOM in children. We review the guideline as well as scientific evidence related to AOM treatment options. We support a set of evidence-based guidelines employing a delayed prescription option for antibiotic therapy in selected children. If used appropriately, these cost-effective guidelines will reduce the amount of antibiotics prescribed, increase parental satisfaction, and may lower rates of antibiotic resistance while producing similar rates of resolution of AOM.

    Children aged 0–2 years (i.e., infants) with acute myeloid leukemia (AML) are a peculiar subgroup of patients in the childhood AML scenario. They present with distinctive biological and clinical characteristics, including a high prevalence of prognostically unfavorable risk factors and an increased susceptibility to therapy-related toxicity. Remarkable improvements have been achieved over the last two decades in the treatment of these patients and their outcome is becoming superimposable to that of the older age groups. In this review, we will focus on peculiarities of this young subgroup of children with AML, describing their clinical presentation, the biology of disease, and factors influencing outcome. Treatment results and toxicity data reported by major collaborative groups are also summarized and compared. PMID:25973412

    This is an exciting time in the treatment of acute lymphoblastic leukemia (ALL) given the advances in the relapsed/refractory setting. The development of antibody treatments (including antibody drug conjugates with toxins) offers a different treatment approach compared with conventional chemotherapy regimens. Moreover, the use of bispecific T-cell-engager antibodies (BiTEs) such as blinatumomab harness the cytotoxic activity of T cells against CD19-positive lymphoblasts. Another strategy involves the use of chimeric antigen receptor (CAR) T cells. CAR T cells have demonstrated promising results in the relapsed/refractory setting. However, the use of BiTEs and CAR T cells is also associated with a distinct set of adverse reactions that must be taken into account by the treating physician. Apart from the above strategies, the use of other targeted therapies has attracted interest. Namely, the discovery of the Philadelphia (Ph)-like signature in children and young adults with ALL has led to the use of tyrosine kinase inhibitors (TKI) in these patients. The different drugs and strategies that are being tested in the relapsed/refractory ALL setting pose a unique challenge in identifying the optimum sequence of treatment and determining which approaches should be considered for frontline treatment.

    Background We conducted a clinical trial to test whether prophylactic cranial irradiation could be omitted in all children with newly diagnosed acute lymphoblastic leukemia. Methods A total of 498 evaluable patients were enrolled. Treatment intensity was based on presenting features and the level of minimal residual disease after remission induction treatment. Continuous complete remission was compared between the 71 patients who previously would have received prophylactic cranial irradiation and the 56 historical controls who received it. Results The 5-year event-free and overall survival probabilities (95% confidence interval) for all 498 patients were 85.6% (79.9% to 91.3%) and 93.5% (89.8% to 97.2%), respectively. The 5-year cumulative risk of isolated central-nervous-system (CNS) relapse was 2.7% (1.1% to 4.2%), and that of any CNS relapse (isolated plus combined) was 3.9% (1.9% to 5.9%). The 71 patients had significantly better continuous complete remission than the 56 historical controls (P=0.04). All 11 patients with isolated CNS relapse remain in second remission for 0.4 to 5.5 years. CNS leukemia (CNS-3 status) or a traumatic lumbar puncture with blasts at diagnosis and a high level of minimal residual disease (≥ 1%) after 6 weeks of remission induction were significantly associated with poorer event-free survival. Risk factors for CNS relapse included the presence of the t(1;19)[TCF3-PBX1], any CNS involvement at diagnosis, and T-cell immunophenotype. Common adverse effects included allergic reactions to L-asparaginase, osteonecrosis, thrombosis, and disseminated fungal infection. Conclusions With effective risk-adjusted chemotherapy, prophylactic cranial irradiation can be safely omitted in the treatment of childhood acute lymphoblastic leukemia. PMID:19553647

    Peripheral neuropathy is a common complication of arsenic toxicity. Symptoms are usually mild and reversible following discontinuation of treatment. A more severe chronic sensorimotor polyneuropathy characterized by distal axonal-loss neuropathy can be seen in chronic arsenic exposure. The clinical course of arsenic neurotoxicity in patients with coexistence of thiamine deficiency is only anecdotally known but this association may potentially lead to severe consequences. We describe a case of acute irreversible axonal neuropathy in a patient with hidden thiamine deficiency who was treated with a short course of arsenic trioxide for acute promyelocytic leukemia. Thiamine replacement therapy and arsenic trioxide discontinuation were not followed by neurological recovery and severe polyneuropathy persisted at 12-month follow-up. Thiamine plasma levels should be measured in patients who are candidate to arsenic trioxide therapy. Prophylactic administration of vitamin B1 may be advisable. The appearance of polyneuropathy signs early during the administration of arsenic trioxide should prompt electrodiagnostic testing to rule out a pattern of axonal neuropathy which would need immediate discontinuation of arsenic trioxide.

We prefer the method used by Brunner, but under general anaesthesia and using a Bentley-Autotransfusion-System (ATS). The average age of our patients was 55 years (age ranged between 17 and 87 years). No lethal pulmonary embolism was observed. 2, 1 percent of the patients died following apoplex or acute heart failure. Of 67 patients who were operated on 6 months ago or more 70 percent have no further complaints, 28 percent still have some residual edema and only 2 patients have a severe postthrombotic syndrome. 50 percent of 40 control-phlebograms demonstrated patency of all veins. 20 percent had short segmentary occlusions with definite signs of recanalisation, while in 27 percent of the cases occlusions of the lower leg and thigh were found, the iliac veins being free. Only 2 postoperative phlebograms showed a complete iliofemoral venous occlusion. Our results prove, that the operative thrombectomy is a successful method, with which the main complications of the iliofemoral thrombosis-pulmonary embolisation and postthrombotic syndrome-can difinitely be reduced. Also because of better long term results, the operative therapy of acute ilofemoral thrombosis should be generally prefered instead of conservative treatment.

    Acute pancreatitis is most frequently of biliary or alcoholic origin and less frequently due to iatrogenic (ERCP, medication) or metabolic causes. Diagnosis is usually based on abdominal pain and elevation of serum lipase to more than three-times the normal limit. Acute pancreatitis can either resolve quickly following an oedematous swelling or present as a severe necrotizing form. A major risk is the systemic inflammatory response syndrome (SIRS), which can cause multi-organ failure. Prediction of disease course is initially difficult, thus necessitating immediate therapy and regular re-evaluation. In order to prove or exclude biliary genesis, abdominal ultrasonography should first be performed and endoscopic ultrasound may also be required. Primary therapy includes rapid and correctly dosed fluid substitution. Biliary pancreatitis requires causal treatment. In the case of cholangitis, stone extraction must be performed immediately; in the absence of cholangitis, it might be advisable to wait for spontaneous stone clearance. Timely cholecystectomy is necessary in all cases of biliary pancreatitis. PMID:25139706

    Acute otitis media (AOM) is a common condition in children that is often treated with systemic antibiotic therapy; however, research suggests that non-complicated AOM will resolve spontaneously using only eardrops. To determine best practice for the use of systematic antibiotics compared to topical treatment of AOM, a systematic review of evidence was conducted. Cochrane, Medline, CINAHL, and other databases were searched. Inclusion criteria were studies published from 1995-2010 that included children with AOM and were randomized controlled trials (RCTs). Five systematic reviews and five RCTs were included in the review. Current evidence recommends using topical and other alternative approaches for treating non-complicated AOM in children 2 years of age or older; however, many practitioners are not currently following these recommendations for various reasons. Additional research to address these reasons may help determine how to improve practitioner adherence to best practice evidence and guidelines to help reduce the unnecessary use of systemic antibiotics.

    Antibiotic treatment of acute otitis media (AOM) accounts for a significant number of all antibiotic prescriptions each year. In the primary care setting, initial antibiotic selection is rarely based on direct evidence, such as cultures of middle ear fluid. Initial antibiotic therapy by the primary care practitioner involves the evaluation and application of information related to prevalence of infecting organisms; in vitro antibiotic spectrum and penetration into middle ear fluid; initial cure rate, relapse and recurrence rates; and antibiotic cost, safety, and convenience. The influence of these factors on the initial antibiotic choice for AOM is reviewed. Several therapeutic dilemmas confronting the prescriber are discussed and a rational approach to initial antibiotic therapy is presented.

    Prognosis of elderly patients with acute myeloid leukemia (AML) remains poor and new treatment approaches are urgently needed. A novel nucleoside analog sapacitabine has recently emerged as a feasible agent because of its oral administration and acceptable toxicity profile. Clinical efficacy of sapacitabine, both as a single agent and in combination, has been evaluated in elderly AML patients or AML patients unfit for standard intensive chemotherapy. Response rates varied from 15 to 45% in phase II studies. Sapacitabine was overall well-tolerated with gastrointestinal and myelosuppression-related complications were the most common side effects. Unfortunately, in a phase III study sapacitabine showed no clinical superiority as compared to low-dose cytarabine (LDAC) in patients with AML. Another large phase III study comparing the combination of sapacitabine with decitabine to decitabine alone is currently ongoing and is expected to be completed by the end of 2015 or by the first half of 2016.

    Generalised acute peritonitis is a relatively frequently pathology which has always been extremely difficult to treat owing to the large number of complications. Considerable progress has been made over the past few years in the surgical treatment of these pathologies following the introduction of new materials accompanied by new techniques: continuous peritoneal lavage (CPL) and laparostomy are the best known. These techniques must be used in carefully selected patients. They allow a marked improvement in results: fewer cases of redo surgery; fewer local and general complications; shorter hospitalisation stay; fewer deaths. These results are possible because these techniques ensure a better cleansing of the peritoneal cavity, with easier removal of necrotic and purulent materials, the main cause of local and general complications.

    Painful neuropathy, a common complication of diabetes mellitus is characterized by allodynia and hyperalgesia. Recent studies emphasized on the role of non-neuronal cells, particularly microglia in the development of neuronal hypersensitivity. The purpose of the present study is to evaluate the effect of minocyline, a selective inhibitor of microglial activation to define the role of neuroimmune activation in experimental diabetic neuropathy. Cold allodynia and thermal and chemical hyperalgesia were assessed and the markers of inflammation and oxidative and nitrosative stress were estimated in streptozotocin-induced diabetic rats. Chronic administration of minocycline (40 and 80 mg/kg, i.p.) for 2 weeks started 2 weeks after diabetes induction attenuated the development of diabetic neuropathy as compared to diabetic control animals. In addition, minocyline treatment reduced the levels of interleukin-1β and tumor necrosis factor-α, lipid peroxidation, nitrite and also improved antioxidant defense in spinal cords of diabetic rats as compared to diabetic control animals. In contrast, minocycline (80 mg/kg, per se) had no effect on any of these behavioral and biochemical parameters assessed in age-matched control animals. The results of the present study strongly suggest that activated microglia are involved in the development of experimental diabetic neuropathy and minocycline exerted its effect probably by inhibition of neuroimmune activation of microglia. In addition, the beneficial effects of minocycline are partly mediated by its anti-inflammatory effect by reducing the levels of proinflammatory cytokines and in part by modulating oxidative and nitrosative stress in the spinal cord that might be involved in attenuating the development of behavioral hypersensitivity in diabetic rats.

    2013-01-01

    High-risk acute myelogenous leukemia (AML) constitutes a distinct subset of disease based on clinical and biological characteristics and comprises a significant percentage of all cases of adult AML. Biologic features such as distinct clonal cytogenetic and molecular abnormalities identify a subgroup of AML patients characterized by poor response to induction chemotherapy and poor long-term survival after treatment with consolidation chemotherapy. Clinical variables that predict for poor response include AML relapsed after less than 1 year of remission and AML characterized by resistance to conventional agents. We review here our understanding of the defining biologic subtypes of AML and discuss how adequate initial evaluation can be used to inform the choice of treatment. By defining high-risk biologic and clinical variables, a strong case can be made for treating patients with investigational agents, with treatment directed at distinct cytogenetic or molecular abnormalities. Allogeneic transplantation is the only form of therapy available outside of the setting of a clinical trial that may offer a chance for long-term survival for patients with high-risk AML.

    Due to the ground breaking consistent evidence that supports the effect of endovascular stroke treatment (EST), many acute care hospitals and stroke centers will have to be prepared to provide this treatment in an optimal way within the coming years. In addition to the intervention itself, patient preparation, stabilization and monitoring during the treatment as well as the aftercare represent significant challenges and have mostly not yet been sufficiently investigated. Under these aspects, the questions of optimal sedation and airway management have received the highest attention. Based on retrospective study results it already seems to be justified, respecting certain criteria, to prefer EST with the patient under conscious sedation (CS) in comparison to general anesthesia (GA) and to only switch to GA in cases of emergency until this question has been clarified by prospective studies. This and other aspects of peri-interventional management, such as logistics, monitoring, blood pressure, ventilation settings, postprocedural steps of intensive or stroke unit care and imaging follow-up are summarized in this overview. The clinical and radiological selection of patients and thus the decision for intervention or technical aspects of the intervention itself will not be part of this article. PMID:26311331

    To evaluate the efficacy of intracranial pressure (ICP)-targeted treatment, compared to standard intensive care, in adults with community acquired acute bacterial meningitis (ABM) and severely impaired consciousness, a prospectively designed intervention-control comparison study was performed. Included were patients with confirmed ABM and severely impaired mental status on admission. Fifty-two patients, given ICP-targeted treatment at a neuro-intensive care unit, and 53 control cases, treated with conventional intensive care, were included. All patients received intensive care with me-chanical ventilation, sedation, antibiotics and corticosteroids according to current guidelines. ICP-targeted treatment was performed in the intervention group, aiming at ICP 50 mmHg. The mortality was significantly lower in the intervention group compared to controls, 5/52 (10%) versus 16/53 (30%). Furthermore, only 17 patients (32%) in the control group fully recovered, compared to 28 (54%) in the intervention group. Early neuro-intensive care using ICP-targeted therapy reduces mortality and improves the overall outcome in adult patients with ABM and severely impaired mental status on admission.

    A healthy woman aged 21 years who used the oral contraceptive Trigynon became pregnant while being treated with Minocin (minocycline; 100 mg per day) for acne conglobata. While the risk of use of antibiotics such as this one reducing the efficacy of oral contraceptives is small, patients should nevertheless be informed that the risk exists.

  16. How assess drugs in the treatment of acute bipolar mania?

    Bipolar affective disorder is a serious mental disease associated with significant morbidity and mortality. Good-quality research available to guide treatment strategies remains insufficient, particularly with regard to manic or hypomanic episodes. A critical review of the various stages of mania might be helpful for pharmaceutical companies and investigators as a prerequisite for the clinical evaluation of potential antimanic properties of medications. The main difficulty is with a comparison between anticonvulsants, antipsychotics, and mood stabilizers such as lithium (with equal efficacy in the acute phase and the prevention of recurrent manic episodes). No consensus has been reached with regard to the treatment of bouts of acute mania in various parts of the world. Controlled clinical trials have, at last, provided irrefutable evidence of the activity of lithium, which has long been used alone, as well as that of divalproate or its derivatives and, to a lesser extent, carbamazepine. The new antipsychotic agents have more recently established their efficacy, especially aripiprazole, asenapine, quetiapine; olanzapine, risperidone, and ziprasidone (not sure where the paradox is). In Europe, haloperidol is still the reference substance used in clinical trials despite the fact that it is not officially indicated in the treatment of mania. In the USA, lithium, divalproate, or antipsychotics can be prescribed as first-line treatment. In Europe, lithium remains the first-line medication, whereas divalproate and atypical antipsychotic agents are used only as second-line therapy. Although both types of medication (antipsychotics, normothymic agents, and/or anticonvulsants) have proved to be clinically effective in the management of mania by reducing the mania scores overall, the same does not apply, however, to all symptoms of mania. Factorial approaches to mania have all shown that since there are several clinical forms of mania, several clusters of manic symptoms can

    Effective antagonism of the P2Y12 platelet receptor is central to the treatment of acute coronary syndrome (ACS) patients, especially in the setting of percutaneous coronary intervention and stenting. According to consensus guidelines, early revascularization and intensive antiplatelet therapy are key to reducing the complications that arise from myocardial ischaemia and the recurrence of cardiovascular events. Until recently, clopidogrel was the key P2Y12 antagonist advocated, but due to several limitations as an antiplatelet agent, newer drugs with more predictable, rapid and potent effects have been developed. Prasugrel and ticagrelor are now the recommended first-line agents in patients presenting with non-ST-segment elevation ACS and ST-segment elevation ACS, due to large-scale randomized trials that demonstrated net clinical benefit of these agents over clopidogrel, as stated in the European guidelines. Although no study has directly compared the two agents, analysis of the data to date suggests that certain patient types, such as diabetics, those with ST-segment elevation myocardial infarction or renal failure and the elderly may have a better outcome with one agent over the other. Further studies are needed to confirm these differences and answer pending questions regarding the use of these drugs to optimize efficacy while minimizing adverse events, such as bleeding. The aim of this review is to provide an overview of the current P2Y12 receptor antagonists in the treatment of ACS, with a focus on issues of appropriate agent selection, timing of treatment, bleeding risk and the future role of personalized treatment using platelet function and genetic testing.

    The Paliperidone ER Treatment in Acute Intervention (PERTAIN) study was designed to explore treatment response, tolerability, and safety of flexible doses of paliperidone ER in patients with schizophrenia admitted for an acute exacerbation. This paper addresses a secondary analysis of PERTAIN data designed to explore predictors for treatment response, flexible dosing, and concomitant benzodiazepine use. This prospective, multicenter, phase 3b, open-label, single-arm, 6-week study used flexible doses of paliperidone ER (3 to 12mg once daily) to treat patients hospitalized for an acute exacerbation of schizophrenia, reflecting more closely daily clinical practice. Predictive models were evaluated for paliperidone ER flexible dosing, treatment response, and concomitant treatment with benzodiazepines as distinct independent variables. For the analysis of explanatory variables, a stepwise logistic regression was used, taking into account patient age, gender, body mass index, diagnosis and duration of schizophrenia, number of prior hospitalizations, psychotic symptoms (PANSS), disease severity (CGI-S), and patient functioning (PSP) at baseline. Early response (defined as response within 2weeks of treatment initiation) was also used as a predictor. Clinical response (defined as ≥30% decrease in PANSS total score and ≥1 point decrease in CGI-S from baseline to endpoint) was predicted by early clinical response (p<0.001) and there was a trend for the diagnosis of paranoid schizophrenia vs. other types of schizophrenia to predict clinical response (p=0.0525). High response (defined as ≥50% decrease in PANSS total score and ≥2 points decrease in CGI-S from baseline to endpoint) was predicted by early high response, higher baseline CGI-S, or female gender. More severely ill patients with a higher baseline CGI-S were twice likely to be treated concomitantly with a benzodiazepine. PMID:24096139

    Population-based data on more than 1 million patients registered in the Surveillance, Epidemiology, and End-Results Program of the National Cancer Institute, 1973-1984, were analyzed to determine the survival of patients with de novo acute nonlymphocytic leukemia (ANLL) and following a first primary tumor treated (with chemotherapy and/or radiation therapy) or untreated. Cases that occurred within 12 months of the first malignant neoplasm were excluded. Survival was estimated using Cox proportional-hazards modeling, with age, sex, and specific type of ANLL as covariates. The 6,271 patients with de novo ANLL had an estimated 12-month survival of 30%, while the 107 patients with treatment-related ANLL had an estimated 12-month survival of 10%. The authors conclude that ANLL that occurs after chemotherapy or radiation therapy is biologically more aggressive and/or resistant to therapy than spontaneous ANLL. This provides a rationale for current studies on treatment-induced cellular changes and on more aggressive therapy for these patients.

    Purpose Investigate antileukemic activity of artemisinins, artesunate (ART), and dihydroartemisinin (DHA), in combination with cytarabine, a key component of acute myeloid leukemia (AML) chemotherapy using in vitro and in vivo models. Methods Using ten human AML cell lines, we conducted a high-throughput screen to identify antimalarial agents with antileukemic activity. We evaluated effects of ART and DHA on cell viability, cytotoxicity, apoptosis, lysosomal integrity, and combination effects with cytarabine in cell lines and primary patient blasts. In vivo pharmacokinetic studies and efficacy of single-agent ART or combination with cytarabine were evaluated in three xenograft models. Results ART and DHA had the most potent activity in a panel of AML cell lines, with selectivity toward samples harboring MLL rearrangements and FLT3-ITD mutations. Combination of ART or DHA was synergistic with cytarabine. Single-dose ART (120 mg/kg) produced human equivalent exposures, but multiple dose daily administration required for in vivo efficacy was not tolerated. Combination treatment produced initial regression, but did not prolong survival in vivo. Conclusions The pharmacology of artemisinins is problematic and should be considered in designing AML treatment strategies with currently available agents. Artemisinins with improved pharmacokinetic properties may offer therapeutic benefit in combination with conventional therapeutic strategies in AML. PMID:27125973

  1. Evaluation and treatment of acute low back pain.

    PubMed

    Kinkade, Scott

    2007-04-15

    Acute low back pain with or without sciatica usually is self-limited and has no serious underlying pathology. For most patients, reassurance, pain medications, and advice to stay active are sufficient. A more thorough evaluation is required in selected patients with "red flag" findings associated with an increased risk of cauda equina syndrome, cancer, infection, or fracture. These patients also require closer follow-up and, in some cases, urgent referral to a surgeon. In patients with nonspecific mechanical low back pain, imaging can be delayed for at least four to six weeks, which usually allows the pain to improve. There is good evidence for the effectiveness of acetaminophen, nonsteroidal anti-inflammatory drugs, skeletal muscle relaxants, heat therapy, physical therapy, and advice to stay active. Spinal manipulative therapy may provide short-term benefits compared with sham therapy but not when compared with conventional treatments. Evidence for the benefit of acupuncture is conflicting, with higher-quality trials showing no benefit. Patient education should focus on the natural history of the back pain, its overall good prognosis, and recommendations for effective treatments. PMID:17477101

    The purpose of this study was to investigate the effects of minocycline on alkali burn-induced corneal neovascularization (CNV). A total of 105 mice treated with alkali burns were randomly divided into three groups to receive intraperitoneal injections of either phosphate buffered saline (PBS) or minocycline twice a day (60 mg/kg or 30 mg/kg) for 14 consecutive days. The area of CNV and corneal epithelial defects was measured on day 4, 7, 10, and14 after alkali burns. On day 14, a histopathological examination was performed to assess morphological change and the infiltration of polymorphonuclear neutrophils (PMNs). The mRNA expression levels of vascular endothelial growth factor (VEGF) and its receptors (VEGFRs), basic fibroblast growth factor (bFGF), matrix metalloproteinases (MMPs), interleukin-1α, 1β, 6 (IL-1α, IL-1β, IL-6) were analyzed using real-time quantitative polymerase chain reaction. The expression of MMP-2 and MMP-9 proteins was determined by gelatin zymography. In addition, enzyme-linked immunosorbent assay was used to analyze the protein levels of VEGFR1, VEGFR2, IL-1β and IL-6. Minocycline at a dose of 60 mg/kg or 30 mg/kg significantly enhanced the recovery of the corneal epithelial defects more than PBS did. There were significant decreases of corneal neovascularization in the group of high-dosage minocycline compared with the control group at all checkpoints. On day 14, the infiltrated PMNs was reduced, and the mRNA expression of VEGFR1, VEGFR2, bFGF, IL-1β, IL-6, MMP-2, MMP-9, -13 as well as the protein expression of VEGFR2, MMP-2, -9, IL-1β, IL-6 in the corneas were down-regulated with the use of 60 mg/kg minocycline twice a day. Our results showed that the intraperitoneal injection of minocycline (60 mg/kg b.i.d.) can significantly inhibit alkali burn-induced corneal neovascularization in mice, possibly by accelerating corneal wound healing and by reducing the production of angiogenic factors, inflammatory cytokines and MMPs.

    Acute heart failure (AHF) represents a major healthcare burden with a high risk of in-hospital and post-discharge mortality, which remained almost unchanged in the last few decades, underscoring the need of new treatments. Relaxin is a naturally occurring human peptide initially identified as a reproductive hormone and has been shown to play a key role in the maternal hemodynamic and renal adjustments that accommodate pregnancy. Recently, the new molecule serelaxin, a recombinant form of the naturally occurring hormone relaxin has been studied in patients hospitalized for AHF. In addition to vasodilation, serelaxin has anti-oxidative, anti-inflammatory and connective tissue regulating properties. In preclinical studies, it reduced both systemic and renal vascular resistance and, in the clinical trials Pre-RELAX-AHF and RELAX-AHF, it improved dyspnea and signs of congestion. In addition, serelaxin was associated with a reduction of 180-day mortality. The aim of this review is to summarize the pharmacological properties of serelaxin and the results of the preclinical and clinical studies. PMID:26294074

    From October 1994 to June 1997, a multidisciplinary team of scientists and engineers at Lawrence Livermore National Laboratory were funded through LDRD to develop and integrate technologies for diagnosis and treatment of acute stroke. The project was summarized in a Science and Technology Review article `Brain Attack` that appeared in June 1997 and again in the Center for Healthcare Technologies Report (UCRL-LR-124761). This article is the best overview of the project, epidemiology of stroke and technical progress. Most of the technical progress has been documented in conference papers and presentations and refereed journal articles. Additional technical publication can be expected as our remaining patent applications progress through the US Patent and Trademark Office. The purpose of this report is to provide an appropriate introduction and organization to the numerous publications so that interested readers can quickly find information. Because there is no documentation for the history of this project, this report provides a summary. It also provides the final status report for the LDRD funding.

    In the acute phase of cerebral infarction, many experimental data suggest that free radicals including superoxide, hydroxy radical and nitric oxide are one of the most important factors to cause brain damage. We have clearly detected nitrotyrosine (a marker of endogenous production of peroxynitrite, which is readily produced from superoxide and nitric oxide) in neurons and intraparenchymal vascular walls during post-ischemic reperfusion. Free radical scavengers thus seem to be very promising tools of treatment, and one of them (edaravone) has recently been approved for clinical use in Japan. CREB (cyclic AMP response element binding protein) is a DNA-binding transcription factor, and its function is activated by phosphorylation of Ser133 residue. CREB plays important roles in neuronal development, synaptic plasticity and regeneration. We have found that phosphorylation of CREB is significantly and persistently increased in surviving neurons and oligodendrocytes in post-ischemic brain, while this phosphorylation is only transiently increased in neurons and oligodendrocytes which eventually die. These data suggest that CREB phosphorylation plays an important role in protection of ischemic brain tissue. Oligodendrocyte progenitor cells (OPC) remain abundant throughout the adult brain, and retain their ability to become not only mature oligodendrocytes, but also neurons. We have recently found that OPC are significantly activated and proliferate in the peri-infarct area at 1-2 weeks after ischemia, suggesting that OPC may be involved in the repair mechanisms of ischemic brain. Future targets of stroke treatment should include enhancement of intrinsic protection mechanisms such as CREB phosphorylation and activation of progenitors cells. PMID:12235793

    This paper is about sinus balloon dilatation in treatment of acute left sphenoid sinusitis with left impaired vision in a child. Balloon catheter dilatation (BCD) of the sinus ostia is a new technique. It has been shown to be a minimally invasive technique to manage chronic sinusitis. However, this method is rarely used in the treatment of acute sinusitis. So far, we know of no reported cases of sinus balloon dilatation in treatment of this case, especially for children.

    Purpose Second malignant neoplasms (SMNs) after diagnosis of childhood acute lymphoblastic leukemia (ALL) are rare events. Patients and Methods We analyzed data on risk factors and outcomes of 642 children with SMNs occurring after treatment for ALL from 18 collaborative study groups between 1980 and 2007. Results Acute myeloid leukemia (AML; n = 186), myelodysplastic syndrome (MDS; n = 69), and nonmeningioma brain tumor (n = 116) were the most common types of SMNs and had the poorest outcome (5-year survival rate, 18.1% ± 2.9%, 31.1% ± 6.2%, and 18.3% ± 3.8%, respectively). Five-year survival estimates for AML were 11.2% ± 2.9% for 125 patients diagnosed before 2000 and 34.1% ± 6.3% for 61 patients diagnosed after 2000 (P < .001); 5-year survival estimates for MDS were 17.1% ± 6.4% (n = 36) and 48.2% ± 10.6% (n = 33; P = .005). Allogeneic stem-cell transplantation failed to improve outcome of secondary myeloid malignancies after adjusting for waiting time to transplantation. Five-year survival rates were above 90% for patients with meningioma, Hodgkin lymphoma, thyroid carcinoma, basal cell carcinoma, and parotid gland tumor, and 68.5% ± 6.4% for those with non-Hodgkin lymphoma. Eighty-nine percent of patients with brain tumors had received cranial irradiation. Solid tumors were associated with cyclophosphamide exposure, and myeloid malignancy was associated with topoisomerase II inhibitors and starting doses of methotrexate of at least 25 mg/m2 per week and mercaptopurine of at least 75 mg/m2 per day. Myeloid malignancies with monosomy 7/5q− were associated with high hyperdiploid ALL karyotypes, whereas 11q23/MLL-rearranged AML or MDS was associated with ALL harboring translocations of t(9;22), t(4;11), t(1;19), and t(12;21) (P = .03). Conclusion SMNs, except for brain tumors, AML, and MDS, have outcomes similar to their primary counterparts. PMID:23690411

    Effects of acute and chronic tianeptine treatments on ethanol withdrawal syndrome were investigated in rats. Ethanol (7.2% v/v) was given to adult male Wistar rats by a liquid diet for 30 days. Acute or chronic (twice daily) tianeptine (5, 10 and 20 mg/kg) and saline were administered to rats intraperitoneally. Acute and last chronic tianeptine injections and saline were done 30 min before ethanol withdrawal testing. After 2nd, 4th and 6th hours of ethanol withdrawal, rats were observed for 5 min, and withdrawal signs which included locomotor hyperactivity, agitation, tremor, wet dog shakes, stereotyped behavior and audiogenic seizures were recorded or rated. Locomotor activity in naive (no ethanol-dependent rats) was also tested after acute tianeptine treatments. Acute but not chronic tianeptine treatment attenuated locomotor hyperactivity and agitation in ethanol-dependent rats. Both acute and chronic tianeptine treatment produced some significant inhibitory effects on tremor, wet dog shakes, stereotyped behaviors and audiogenic seizures during the ethanol withdrawal. Our results suggest that acute or chronic tianeptine treatment attenuates ethanol withdrawal syndrome in ethanol-dependent rats and this drug may be useful for treatment of ethanol-type dependence.

    Background Older age has historically been an adverse prognostic factor in pediatric acute myeloid leukemia (AML). The impact of age relative to that of other prognostic factors on the outcome of patients treated in recent trials is unknown. Methods Clinical outcome and causes of treatment failure of 351 patients enrolled on three consecutive protocols for childhood AML between 1991 and 2008 were analyzed according to age and protocol. Results The more recent protocol (AML02) produced improved outcomes for 10- to 21-year-old patients compared to 2 earlier studies (AML91 and 97), with 3-year rates of event-free survival (EFS), overall survival (OS) and cumulative incidence of refractory leukemia or relapse (CIR) for this group similar to those of 0- to 9-year old patients: EFS, 58.3% ± 5.4% vs. 66.6% ± 4.9%, P=.20; OS, 68.9% ± 5.1% vs. 75.1% ± 4.5%, P=.36; cumulative incidence of refractory leukemia or relapse, 21.9% ± 4.4%; vs. 25.3% ± 4.1%, P=.59. EFS and OS estimates for 10–15-year-old patients overlapped those for 16–21-year-old patients. However, the cumulative incidence of toxic death was significantly higher for 10- to 21-year-old patients compared to younger patients (13.2% ± 3.6 vs. 4.5% ± 2.0%, P=.028). Conclusion The survival rate for older children with AML has improved on our recent trial and is now similar to that of younger patients. However, deaths from toxicity remain a significant problem in the older age group. Future trials should focus on improving supportive care while striving to develop more effective antileukemic therapy. PMID:22674050

    RNA interference has tremendous yet unrealized potential to treat a wide range of illnesses. Innovative solutions are needed to protect and selectively deliver small interfering RNA (siRNA) cargo to and within a target cell to fully exploit siRNA as a therapeutic tool in vivo. Herein, we describe ammonium-functionalized carbon nanotube (fCNT)–mediated transport of siRNA selectively and with high efficiency to renal proximal tubule cells in animal models of acute kidney injury (AKI). fCNT enhanced siRNA delivery to tubule cells compared to siRNA alone and effectively knocked down the expression of several target genes, including Trp53, Mep1b, Ctr1, and EGFP. A clinically relevant cisplatin-induced murine model of AKI was used to evaluate the therapeutic potential of fCNT-targeted siRNA to effectively halt the pathogenesis of renal injury. Prophylactic treatment with a combination of fCNT/siMep1b and fCNT/siTrp53 significantly improved progression-free survival compared to controls via a mechanism that required concurrent reduction of meprin-1β and p53 expression. The fCNT/siRNA was well tolerated, and no toxicological consequences were observed in murine models. Toward clinical application of this platform, fCNTs were evaluated for the first time in nonhuman primates. The rapid and kidney-specific pharmacokinetic profile of fCNT in primates was comparable to what was observed in mice and suggests that this approach is amenable for use in humans. The nanocarbon-mediated delivery of siRNA provides a therapeutic means for the prevention of AKI to safely overcome the persistent barrier of nephrotoxicity during medical intervention.

    Gallogly, Molly Megan; Lazarus, Hillard M

    2016-01-01

    Acute myeloid leukemia (AML) is a hematologic malignancy that carries a poor prognosis and has garnered few treatment advances in the last few decades. Mutation of the internal tandem duplication (ITD) region of fms-like tyrosine kinase (FLT3) is considered high risk for decreased response and overall survival. Midostaurin is a Type III receptor tyrosine kinase inhibitor found to inhibit FLT3 and other receptor tyrosine kinases, including platelet-derived growth factor receptors, cyclin-dependent kinase 1, src, c-kit, and vascular endothelial growth factor receptor. In preclinical studies, midostaurin exhibited broad-spectrum antitumor activity toward a wide range of tumor xenografts, as well as an FLT3-ITD-driven mouse model of myelodysplastic syndrome (MDS). Midostaurin is orally administered and generally well tolerated as a single agent; hematologic toxicity increases substantially when administered in combination with standard induction chemotherapy. Clinical trials primarily have focused on relapsed/refractory AML and MDS and included single- and combination-agent studies. Administration of midostaurin to relapsed/refractory MDS and AML patients confers a robust anti-blast response sufficient to bridge a minority of patients to transplant. In combination with histone deacetylase inhibitors, responses appear comparable to historic controls, while the addition of midostaurin to standard induction chemotherapy may prolong survival in FLT3-ITD mutant patients. The response of some wild-type (WT)-FLT3 patients to midostaurin therapy is consistent with midostaurin’s ability to inhibit WT-FLT3 in vitro, and also may reflect overexpression of WT-FLT3 in those patients and/or off-target effects such as inhibition of kinases other than FLT3. Midostaurin represents a well-tolerated, easily administered oral agent with the potential to bridge mutant and WT-FLT3 AML patients to transplant and possibly deepen response to induction chemotherapy.

    In this randomised, double-blind study carried out in 28 centres, azithromycin (500 mg single dose on day 1, followed by 250 mg once-daily on days 2-5) was compared with cefaclor (500 mg t.i.d. for 10 days) in the treatment of acute bacterial pneumonia. A total of 119 patients entered the study, and of these 71 were evaluable and included in the efficacy analysis. The overall satisfactory clinical response was 97.3% for azithromycin patients and 100% for cefaclor patients. The clinical cure rates of azithromycin and cefaclor were 46.9% and 41.0%, respectively; improvement was seen in an additional 46.9% of azithromycin-treated patients and in 59.0% of the cefaclor group. The bacteriological eradication rates were 80.4% and 92.6%, respectively. These rates of clinical and bacteriological efficacy, were not statistically different. Both antibiotics were well tolerated during the study; only two patients (one on each study drug) discontinued medication due to adverse events. The overall incidence of side effects was 18.9% (10 of 53 patients) for azithromycin- and 12.1% (eight of 66 patients) for cefaclor-treated patients. Gastrointestinal disturbances were the most commonly reported side effects (nine of 10 azithromycin-treated patients and six of eight cefaclor-treated patients). In addition, two cefaclor patients reported headache. All azithromycin side effects were mild or moderate in severity, but there were two severe occurrences in the cefaclor group (1 nausea, 1 vomiting) the later leading to discontinuation.(ABSTRACT TRUNCATED AT 250 WORDS)

In the last two decades, growing evidence has been published about the use of antibiotics as the exclusive treatment for acute appendicitis. Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified only one systematic review including one pertinent randomized trial. We generated a summary of findings following the GRADE approach. We concluded the use of antibiotics to treat acute uncomplicated appendicitis may be less effective than appendectomy and probably increases major complications compared with appendectomy.

    Background: Peripancreatic fluid collection suggests the anatomical-clinical scenario of necrotizing acute pancreatitis. However, intrahepatic fluid collection is a rare occurrence with fewer than 30 cases being reported in the medical literature. We describe 2 cases of intrahepatic fluid collection in 2 patients with acute biliary pancreatitis and discuss the therapeutic possibilities. Case Reports: The first case report is that of a 68-year-old female with a diagnosis of acute biliary pancreatitis with several necrotizing fluid collections and a large infected intrahepatic collection in the left lobe. The patient was successfully treated by percutaneous US/CT guided drainage. The second case report is that of a 72-year-old female with a diagnosis of acute biliary pancreatitis with several peripancreatic fluid collections and a voluminous intrahepatic fluid collection in the left lobe that caused epigastric pain. This patient was also successfully treated with percutaneous US/CT guided drainage. Conclusion: Intrahepatic fluid collection in the course of acute biliary pancreatitis is a rare occurrence. The therapeutic approach is the same as that for pancreatic and peripancreatic fluid collections. In case of infection, the patient undergoes percutaneous US/CT guided drainage. This therapeutic procedure can be added to the therapeutic program for necrotizing acute biliary pancreatitis together with ERCP/ES and videolaparocholecystectomy (VLC). PMID:19660231

    While a plethora of studies support a therapeutic benefit of Nrf2 activation and ROS inhibition in diabetic nephropathy (dNP), the Nrf2 activator bardoxolone failed in clinical studies in type 2 diabetic patients due to cardiovascular side effects. Hence, alternative approaches to target Nrf2 are required. Intriguingly, the tetracycline antibiotic minocycline, which has been in clinical use for decades, has been shown to convey anti-inflammatory effects in diabetic patients and nephroprotection in rodent models of dNP. However, the mechanism underlying the nephroprotection remains unknown. Here we show that minocycline protects against dNP in mouse models of type 1 and type 2 diabetes, while caspase -3,-6,-7,-8 and -10 inhibition is insufficient, indicating a function of minocycline independent of apoptosis inhibition. Minocycline stabilizes endogenous Nrf2 in kidneys of db/db mice, thus dampening ROS-induced inflammasome activation in the kidney. Indeed, minocycline exerts antioxidant effects in vitro and in vivo, reducing glomerular markers of oxidative stress. Minocycline reduces ubiquitination of the redox-sensitive transcription factor Nrf2 and increases its protein levels. Accordingly, minocycline mediated Nlrp3 inflammasome inhibition and amelioration of dNP are abolished in diabetic Nrf2−/− mice. Taken together, we uncover a new function of minocycline, which stabilizes the redox-sensitive transcription factor Nrf2, thus protecting from dNP. PMID:27721446

    Purpose: Topotecan (TPT), a camptothecin analog, is currently used to treat human ovarian and small-cell lung cancer and is in clinical trials for other tumor sites. However, it is unknown whether chronomodulation of TPT treatment is beneficial. We examined the effects of administering TPT or X-radiation (XR) alone at different times of the day or night. Methods: We treated mice bearing human colorectal tumor xenografts at four different times representing the early rest period (9 AM or 3 HALO [hours after light onset]), late rest period (3 PM or 9 HALO), early active period (9 PM or 15 HALO), and late active period (3 AM or 21 HALO) of the mice. We gave either TPT (12 mg/kg, injected i.p.) or XR (4 Gy, directed to the tumor) twice weekly on Days 0, 4, 7, 10 within 2 weeks. Results: Treatment with either TPT or XR at 3 AM demonstrated the greatest efficacy (measured by a tumor regrowth assay) without significantly increasing acute toxicity (assessed by a decrease in leukocyte counts or body weight). Conversely, treatment at 3 PM, in particular, showed increased toxicity without any enhanced efficacy. Conclusions: Our study provided the first evidence that chronomodulation of TPT treatments, consistent with the findings of other camptothecin analogs, is potentially clinically beneficial. Additionally, our findings suggest that chronomodulation of fractionated XR treatments is also potentially clinically beneficial.

    2010-01-01

    We present a unique case of toxic epidermal necrolysis (TEN) caused by cetuximab plus minocycline during chemoradiation for recurrent squamous cell carcinoma of the head and neck (SCCHN). In April 2008, a 49-year-old man was diagnosed with recurrent SCCHN. He received surgery and postoperative adjuvant therapy with cetuximab plus chemoradiation. Because of exacerbation of acneform rash by cetuximab, minocycline was added thereafter. However, TEN appeared after the fifth course of weekly cetuximab, and cetuximab plus minocycline was assumed to be the cause. Cetuximab plus minocycline carries a risk of evoking TEN, and the side effects of chemoradiation for SCCHN mask some early signs of TEN. Noticing the transformation of skin lesions makes early diagnosis possible, and prompt cessation of the causative agent is essential for patients with TEN. We review the literature on cetuximab, minocycline, and TEN and discuss the impact of TEN on cancer therapy.

    Recently, minocycline, a tetracycline antibiotic, has been reported to improve symptoms of psychiatric disorders and to facilitate sober decision-making in healthy human subjects. Here we show that minocycline also reduces the risk of the ‘honey trap’ during an economic exchange. Males tend to cooperate with physically attractive females without careful evaluation of their trustworthiness, resulting in betrayal by the female. In this experiment, healthy male participants made risky choices (whether or not to trust female partners, identified only by photograph, who had decided in advance to exploit the male participants). The results show that trusting behaviour in male participants significantly increased in relation to the perceived attractiveness of the female partner, but that attractiveness did not impact trusting behaviour in the minocycline group. Animal studies have shown that minocycline inhibits microglial activities. Therefore, this minocycline effect may shed new light on the unknown roles microglia play in human mental activities.

    There is no standard approved treatment for acute hepatitis C and the combination of pegylated interferon-alpha and ribavirin, currently recognized as the standard of care for chronic hepatitis C, has not been evaluated for acute hepatitis C. Adverse events induced by interferon therapy are numerous but myopathy is rare and has not been described with the use of pegylated interferon-alpha. We report the case of a 33-year-old Caucasian man who was successfully treated for acute hepatitis C with the combination of pegylated interferon-alpha2b and ribavirin, and who during treatment developed myopathy which proved reversible.

    Standard imaging in acute stroke is undertaken with the aim of diagnosing the underlying cause and excluding stroke mimics. In the presence of ischaemic stroke, imaging is also needed to assess patient suitability for treatment with intravenous thrombolysis. Non-contrast CT is predominantly used, but MRI can also exclude any contraindications to thrombolysis treatment. Advanced stroke imaging such as CT and MR angiography and perfusion imaging are increasingly used in an acute setting. In this review, we discuss the evidence for the application of these advanced techniques in the imaging of acute stroke. PMID:24936980

    Minocycline, an antibiotic of the tetracycline family, has attracted considerable interest for its theoretical therapeutic applications in neurodegenerative diseases. However, the mechanism of action underlying its effect remains elusive. Here we have studied the effect of minocycline under excitotoxic conditions. Fluorescence and bioluminescence imaging studies in rat cerebellar granular neuron cultures using fura2/AM and mitochondria-targeted aequorin revealed that minocycline, at concentrations higher than those shown to block inflammation and inflammation-induced neuronal death, inhibited NMDA-induced cytosolic and mitochondrial rises in Ca(2+) concentrations in a reversible manner. Moreover, minocycline added in the course of NMDA stimulation decreased Ca(2+) intracellular levels, but not when induced by depolarization with a high K(+) medium. We also found that minocycline, at the same concentrations, partially depolarized mitochondria by about 5-30 mV, prevented mitochondrial Ca(2+) uptake under conditions of environmental stress, and abrogated NMDA-induced reactive oxygen species (ROS) formation. Consistently, minocycline also abrogates the rise in ROS induced by 75 microM Ca(2+) in isolated brain mitochondria. In search for the mechanism of mitochondrial depolarization, we found that minocycline markedly inhibited state 3 respiration of rat brain mitochondria, although distinctly increased oxygen uptake in state 4. Minocycline inhibited NADH-cytochrome c reductase and cytochrome c oxidase activities, whereas the activity of succinate-cytochrome c reductase was not modified, suggesting selective inhibition of complexes I and IV. Finally, minocycline affected activity of voltage-dependent anion channel (VDAC) as determined in the reconstituted system. Taken together, our results indicate that mitochondria are a critical factor in minocycline-mediated neuroprotection.

  8. Contemporary results of treatment of acute arterial mesenteric thrombosis: has endovascular treatment improved outcomes?

    Acute mesenteric ischemia is an uncommon but highly complex clinical problem and carries a high mortality. Traditional treatment has yielded only modest improvements in mortality and an endovascular first treatment paradigm has been adopted by selected centers over the past decade. However, the technique does not allow for immediate assessment of intestinal viability and availability of the expertise and equipment is mostly limited to tertiary referral centers. Experience gained with endovascular treatment thus far suggests that careful patient selection, procedure planning, and meticulous technique are the key to further improving results. Most important, prolonged attempts at percutaneous intervention should not be allowed to delay laparotomy and bowel assessment. In patients requiring urgent laparotomy, intraoperative retrograde superior mesenteric artery recanalization remains an attractive option and should be given due consideration. Liberal use of second-look laparotomy is to be encouraged for continued bowel assessment and eventual reestablishment of bowel continuity. Early recognition of the problem with expeditious implementation of the appropriate treatment is likely to improve outcomes of this challenging problem in the future.

    Treatment for acute hepatitis C virus (HCV) infection has significantly better outcomes than treatment for chronic infection. The short window of the acute period poses challenges for young injection drug users (IDU), who are at highest risk of HCV infection, to demonstrate treatment candidacy. We recruited patients with acute HCV from a prospective cohort study to examine clinical and behavioral issues related to treatment candidacy. We report on outcomes and how nursing case management affected candidacy. All five acutely-infected participants reported daily drug use at baseline. All established primary care and decreased their drug use. None received treatment for their acute infection; one was treated within 12 months of infection. Establishing treatment candidacy for young IDU in the acute phase involves various health domains. An acute infection's short period poses many challenges to establishing candidacy, but it is a window of opportunity to engage young IDU in health care. PMID:21497111

    Hypertension is the leading risk factor for ischemic and intracerebral hemorrhagic subtypes of stroke. Additionally, high blood pressure (BP) in the acute cerebrovascular event is associated with poor outcome, and a high percentage of stroke survivors have inadequate control of hypertension. The present is a systematic review of prospective, randomized, and controlled trials carried out on safety and efficacy of antihypertensive treatment of both subtypes of acute stroke. Six trials involving 7512 patients were included, which revealed controversies on the speed and the goals of treatment. These controversies could be due at least in part, from the fact that some studies analyzed the results of antihypertensive treatment in ischemic and intracerebral hemorrhagic subtypes of acute stroke together, and from a different prevalence of past-stroke in the randomized groups. Further research is necessary to establish whether standard antihypertensive treatment provides greater benefit than simple observation in patients with ischemic acute stroke and Stage 2 hypertension of JNC 7, albeit they were not candidates for acute reperfusion. In that case, the target reduction in BP could be 10% to 15% within 24 hours. The recently published INTERACT 2 has provided evidence that patients with hemorrhagic stroke may receive intensive antihypertensive treatment safely with the goal of reducing systolic BP to levels no lower than 130 mm Hg. It is important to take into account that marked BP lowering in acute stroke increases the risk of poor outcome by worsening cerebral ischemia from deterioration of cerebral blood flow autoregulation.

    Acute porphyrias are caused by the inherited decreased activity of the enzymes of the heme biosynthesis pathway. Depending on the affected enzyme there are 4 types of them: acute intermittent porphyria, porphyria variegata, coproporphyria and delta-aminolevulinic acid dehydratase deficient porphyria, listed in order of their frequency. Basically the clinical picture is the same in the four types of acute porphyria. The most frequent complaints and symptoms are: cramping abdominal pain, nausea, vomiting, muscle weakness of the limbs then, in the advanced phase, there is a red-colored urine, hyponatremia, subileus, acute psychosis and Landry-type paralysis. Without proper treatment death is caused by respiratory paralysis or serious arrhythmia. In case of suspicion of acute porphyria it is mandatory to identify the type of the acute porphyria and the actual status of the patient. The later indicates what kind of treatment should be used. In the acute phase the early therapy with heme arginate is the treatment of choice. Since the clinical symptoms are precipitated by endogenous or exogenous inducing factors--most often by drugs-, the drugs negatively affecting the heme biosynthesis should be omitted at once even in the suspicion of acute porphyria. The role of the inducing factors in the manifestation of the clinical symptoms makes possible the prevention. It is possible to avoid the inducing factors and this way to prevent the acute attack if the acute porphyrias are recognized in time and the patients and the carriers are under regular control. The patients receive special identification card and the up-to-date list of safe drugs. They can use only these drugs in any kind of illness. Other drugs should be considered as porphyrinogenic since it is impossible to predict based on their chemical structure if they negatively affect the heme biosynthesis.

    Our aim is to present midterm results after endovascular repair of acute and chronic blunt aortic injury. Between December 1999 and December 2005, 13 patients were endovascularly treated for blunt aortic injury. Ten patients, 8 men and 2 women, mean age 38.7 years, were treated for acute traumatic injury in the isthmus region of thoracic aorta. Stent-graftings were performed between the fifth hour and the sixth day after injury. Three patients (all males; mean age, 66 years; range, 59-71 years) were treated due to the presence of symptoms of chronic posttraumatic pseudoaneurysm of the thoracic aorta (mean time after injury, 29.4 years, range, 28-32). Fifteen stent-grafts were implanted in 13 patients. In the group with acute aortic injury one patient died due to failure of endovascular technique. Lower leg paraparesis appeared in one patient; the other eight patients were regularly followed up (1-72 months; mean, 35.6 months), without complications. In the group with posttraumatic pseudoaneurysms all three patients are alive. One patient suffered postoperatively from upper arm claudication, which was treated by carotidosubclavian bypass. We conclude that the endoluminal technique can be used successfully in the acute repair of aortic trauma and its consequences. Midterm results are satisfactory, with a low incidence of neurologic complications.

    Acute pancreatitis is an acute inflammatory disease of the pancreas, with variable involvement of other regional tissues or remote organ systems. Acute pancreatitis is mild in 80% of cases; virtually all patients with this form of disease will survive, because it's associated with minimal organ dysfunction and uneventful recovery; the severe pancreatitis develops in 20% of cases and is associated with higher morbidity and mortality. It's most important to identify the severity of disease at the moment of hospital admission; many scoring systems have been developed to serve as early prognostic signs: Ranson's criteria, Imrie's criteria, Apache II score, Balthazar's TC score. Recently, new drugs have been proposed in the treatment of acute pancreatitis, as, for example, calcitonine, glucagon, systemic antioxidants, antagonists of the receptors of interleukines, antiproteases (aprotinin and gabexate-mesilate) and the inhibitors of pancreatic secretions (somatostatin and its analogues). However, many controversies still exist concerning the real efficacy of these drugs in the treatment of acute pancreatitis, particularly regarding the inhibitors of pancreatic secretions: recently, some studies showed that somatostatin is able to actually reduce the local complication of the disease and the development of severe forms of acute pancreatitis; on the other hand, other studies failed to show real advantages of somatostatin reducing morbidity and mortality for pancreatitis. The aim of present study is a retrospective analysis of patients affected by acute pancreatitis in order to evaluate efficacy of somatostatin and its analogues. All patients subdivided in two groups: group A, patients treated with conventional therapy plus somatostatin and/or octreotide (SS/LS), and group B, patients treated only with conventional therapy. Results seem to show that somatostatin does not positively affect morbidity and mortality in patients with acute pancreatitis. The Authors conclude

    We report the case of a patient with narrow angles who had an attack of bilateral acute angle-closure glaucoma precipitated by dexfenfluramine, a serotoninergic drug developed for appetite suppression. Although the exact mechanism remains uncertain, the pupillary block observed in our case may be the result of the serotoninergic or indirect parasympatholytic properties of the drug on the iris sphincter muscle. Serotonergic psychoactive drugs should be prescribed cautiously in patients with known narrow angles and should be monitored by an ophthalmologist.

    Acute and subacute ischemia of the legs in acute and subacute femoropopliteal bypass occlusion is a dramatic situation that endangers the survival of the limbs, depending on the severity of the ischemia. Different therapy options like percutaneous mechanical thrombectomy procedures, which include rotational thrombectomy, have become available in recent years, in addition to local lysis and surgical thrombectomy. Surgical thrombectomy using the Fogarty catheter technique, in particular, shows an increased incidence of perioperative complications but only small technical success rates in randomized trials. On the other hand, local lysis is associated with increased costs due to resource-consuming measures, such as intensive monitoring and repeat angiographies, in addition to bleeding complications. In the past, further development of the Straub Rotarex® system as an endovascular therapy option has demonstrated good success leading to amputation-free survival in multiple studies. At the same time, a low rate of complications with use has been documented. Most examinations have been conducted in the thigh. To date, there are little investigational data on its use in acutely and subacutely occluded femoropopliteal bypasses. In this paper, the current study-based significance of the Rotarex system for this indication is analyzed based on the existing literature and the authors’ own experiences with 22 patients.

    1993-06-01

    We report our clinical experience with a group of 14 patients who presented with acute myocardial infarction. A holmium:YAG laser was applied to the infarct-related artery. This laser emits 250 - 600 mJ per pulse, with a pulse length of 250 microseconds and repetition rate of 5 Hz. Potential benefits of acute thrombolysis by lasers include the absence of systemic lytic state; a shortened thrombus clearing time relative to using thrombolytics; safe removal of the intracoronary thrombus and facilitation of adjunct balloon angioplasty. Potential clinical difficulties include targeting the obstructive clot and plaque, creation of debris and distal emboli and laser-tissue damage. It is conceivable that holmium:YAG laser can be a successful thrombolytic device as its wave length (2.1 microns) coincides with strong water absorption peaks. Since it is common to find an atherosclerotic plaque located under or distal to the thrombotic occlusion, this laser can also be applied for plaque ablation, and the patient presenting with acute myocardial infarction can clearly benefit from the combined function of this laser system.

    Earlier intervention in acute HIV infection limits HIV reservoirs and may decrease HIV transmission. We developed criteria for empiric antiretroviral therapy (ART) in an emergency department (ED) routine HIV screening program. We assessed the feasibility and willingness of patients with suspected acute HIV infection in the ED to begin ART. A suspected acute HIV infection was defined as a positive HIV antigen antibody combination immunoassay with pending HIV-antibody differentiation test results and HIV RNA viral load. During the study period, there were 16 confirmed cases of acute HIV infection: 11 met our criteria for empiric ART and agreed to treatment, 10 were prescribed ART, and 1 left the ED against medical advice without a prescription for ART. Eight patients completed at least one follow-up visit. Empiric HIV treatment in an ED is feasible, well received by patients, and offers a unique entry point into the HIV care continuum.

    Peculiarities of clinical course, diagnosis and treatment of elderly patients for an acute pancreatitis were analyzed. There was established, that the clinical course of an acute pancreatitis is atypical with obscure symptoms. Late admittance to hospital, presence of concomitant diseases, low reactivity of the organism defense systems, morpho-functional changes in pancreatic gland complicate the early diagnosis. While the abdominal pain occurrence in the patient it is necessary always to keep in mind the diagnosis of an acute pancreatitis and not to rely on the diagnosis with which the patient was delivered to hospital. Because of presence of several concomitant diseases in a patient with an acute pancreatitis the treatment must be multimodal with multidisciplinary approach, including surgeon, anesthesiologist and therapeutist. Operative intervention is mandatory only in presence of a life-threatening complications and in insufficiency of conservative therapy. Miniinvasive technologies constitute the first-line procedures.

When the bleeding occurred due to straddle injury in adolescent girl, experienced gynecological examination and treatment were very important. We experienced a case of straddle injury to the posterior fourchette that caused acute hematocolpos due to delayed adequate treatment with hypotension and acute abdomen in an adolescent girl. This case shows the importance of careful and accurate physical and gynecological examination and adequate and prompt treatment of genital trauma in adolescent girls.

    Acute myelogenous leukemia is a heterogeneous disease. Recent molecular mutational analysis techniques have shed more light on different, genetically well characterised types of the disease. Treatment approach is uniform except for acute promyelocytic leukemia. Application of the "3 + 7" induction treatment has been the gold standard in the past 40 years. While the dose of cytarabine has not been changed, escalating daunorubicine dose in younger (<60 years) patients with good performance status to 90 mg/m(2) had a positive impact on overall survival. High dose chemotherapy is tolerated poorly in patients older than 60 years of age and, as treatment is not curative in the elderly, improvement of overall survival and quality of life remains the main goal of management in these patients. Low intensity treatment is beneficial and can provide additional advantage over supportive care. Innovative and targeted therapy approaches might give promise to better management of patients with acute myelogenous leukemia.

    Abstract The Department of Defense (DoD) and the National Center for Complementary and Alternative Medicine (NCCAM) at the National Institutes of Health (NIH) cosponsored a workshop that explored the possible benefits of acupuncture treatment for acute pain. One goal of the workshop was to establish a roadmap to building an evidence base on that would indicate whether acupuncture is helpful for treating active-duty military personnel experiencing acute pain. The workshop highlighted brief presentations on the most current research on acupuncture and acute pain mechanisms. The impact of various modifiers (stress, genetics, population, phenotypes, etc.) on acute pain pathways and response to acupuncture treatment was discussed. Additional presentations focused on common neural mechanisms, an overview of real-world experience with using acupuncture to treat traumatic acute pain, and best tools and methods specific for acupuncture studies. Three breakout groups addressed the gaps, opportunities, and barriers to acupuncture use for acute pain in military and trauma settings. Different models of effectiveness research and optimal research designs for conducting trials in acute traumatic pain were also discussed. PMID:23020611

    Oral capecitabine is a prodrug of 5-fluorouracil that has been used into the management of multiple cancers because of the convenience of administration and efficacy at least comparable with 5-fluorouracil. While cardiac complications associated with the use of 5-fluorouracil are well-documented, capecitabine-induced acute coronary syndrome has rarely been reported and often attributed to coronary vasospasm. We report a patient presented with acute coronary syndrome secondary to thrombotic coronary occlusion following treatment with oral capecitabine and intravenous oxaliplatin after resection of non-metastatic, node positive colon carcinoma. Capecitabine may induce acute coronary thrombotic occlusion in addition to coronary vasospasm. PMID:25246465

    Minocycline, a second-generation tetracycline, is well known for its antibiotic, anti-inflammatory, and antinociceptive effects. Modulation of synaptic transmission is one of the analgesic mechanisms of minocycline. Although it has been reported that minocycline may suppress excitatory glutamatergic synaptic transmission, it remains unclear whether it could affect inhibitory synaptic transmission, which also plays a key role in modulating pain signaling. To examine the effect of minocycline on synaptic transmission in rat spinal substantia gelatinosa (SG) neurons, we recorded spontaneous inhibitory postsynaptic currents (sIPSCs) using whole-cell patch-clamp recording at a holding potential of 0 mV. Bath application of minocycline significantly increased the frequency but not the amplitude of sIPSCs in a reversible and concentration-dependent manner with an EC50 of 85. The enhancement of inhibitory synaptic transmission produced by minocycline was not affected by the glutamate receptor antagonists CNQX and D-APV or by the voltage-gated sodium channel blocker tetrodotoxin (TTX). Moreover, the potency of minocycline for facilitating sIPSC frequency was the same in both glycinergic and GABAergic sIPSCs without changing their decay phases. However, the facilitatory effect of minocycline on sIPSCs was eliminated in a Ca(2+)-free Krebs solution or by co-administration with calcium channel blockers. In summary, our data demonstrate that baseline inhibitory synaptic transmission in SG neurons is markedly enhanced by minocycline. This may function to decrease the excitability of SG neurons, thus leading to a modulation of nociceptive transmission. PMID:26826332

    Aim: To investigate the mechanisms underlying the anti-nociceptive effect of minocycline on bone cancer pain (BCP) in rats. Methods: A rat model of BCP was established by inoculating Walker 256 mammary carcinoma cells into tibial medullary canal. Two weeks later, the rats were injected with minocycline (50, 100 μg, intrathecally; or 40, 80 mg/kg, ip) twice daily for 3 consecutive days. Mechanical paw withdrawal threshold (PWT) was used to assess pain behavior. After the rats were euthanized, spinal cords were harvested for immunoblotting analyses. The effects of minocycline on NF-κB activation were also examined in primary rat astrocytes stimulated with IL-1β in vitro. Results: BCP rats had marked bone destruction, and showed mechanical tactile allodynia on d 7 and d 14 after the operation. Intrathecal injection of minocycline (100 μg) or intraperitoneal injection of minocycline (80 mg/kg) reversed BCP-induced mechanical tactile allodynia. Furthermore, intraperitoneal injection of minocycline (80 mg/kg) reversed BCP-induced upregulation of GFAP (astrocyte marker) and PSD95 in spinal cord. Moreover, intraperitoneal injection of minocycline (80 mg/kg) reversed BCP-induced upregulation of NF-κB, p-IKKα and IκBα in spinal cord. In IL-1β-stimulated primary rat astrocytes, pretreatment with minocycline (75, 100 μmol/L) significantly inhibited the translocation of NF-κB to nucleus. Conclusion: Minocycline effectively alleviates BCP by inhibiting the NF-κB signaling pathway in spinal astrocytes. PMID:27157092

    Recent data suggest that opioids can activate immune-like cells of the central nervous system (glia). This opioid-induced glial activation is associated with decreased analgesia, owing to the release of proinflammatory mediators. Here we examine in rats whether the putative microglial inhibitor, minocycline, may affect morphine-induced respiratory depression and/or morphine-induced reward (conditioned place preference). Systemic co-administration of minocycline significantly attenuated morphine-induced reductions in tidal volume, minute volume, inspiratory force and expiratory force, but did not affect morphine-induced reductions in respiratory rate. Minocycline attenuation of respiratory depression was also paralleled with significant attenuation by minocycline of morphine-induced reductions in blood oxygen saturation. Minocycline also attenuated morphine conditioned place preference. Minocycline did not simply reduce all actions of morphine, as morphine analgesia was significantly potentiated by minocycline co-administration. Lastly, morphine dose-dependently increased cyclooxygenase-1 gene expression in a rat microglial cell line, an effect that was dose-dependently blocked by minocycline. Together, these data support that morphine can directly activate microglia in a minocycline-suppressible manner and suggest a pivotal role for minocycline-sensitive processes in the mechanisms of morphine-induced respiration depression, reward, and pain modulation.

    We studied 35 patients meeting DSM-III criteria for schizophrenia, paranoid or undifferentiated type, chronic with acute exacerbation. All were treated in hospital, 13 on a psychiatric intensive care unit, and 22 on an open ward. The former unit is a more structured and less stimulating one. We found those patients treated on that ward to show greater improvement in BPRS ratings during the first 2 days of hospitalization compared to the open-ward group, despite similar doses of medication being utilized. Additionally, this improvement was noted to occur among BPRS items comprising a psychotic subscale.

    Acute adrenal haemorrhage (AAH) is a rare disorder with different aetiologies. Aiming to discuss this condition, this report deals with four different cases that will be analysed and examined below, each one of them confirmed by biopsy or surgery and followed clinically and radiologically. In these cases it was found that the patients suffered from localized abdominal pain (4/4) and fever (2/4); one patient had adrenal insufficiency due to bilateral massive AAH. Therefore we concluded that AAH is an uncommon condition with variable clinical manifestations. PMID:9089038

    Introduction: Acute intoxications with corrosive substances can cause severe chemical injuries of the upper gastrointestinal tract, most often located in the mouth, pharynx, esophagus, stomach and duodenum. If a patient survives the acute phase of intoxication, regenerative response may result in esophageal and/or gastric stenosis, and increased risk of esophageal and gastric cancer. Such intoxication may be fatal due to perforation or tracheal necrosis. Enteral nutrition is a nutritional method when nutritional substances are administered through specially designed tubing placed through the nose or percutaneously, directly into the GIT. Aim: The aim of this study is to describe the methods of artificial nutrition in patients with acute corrosive intoxications and the importance of nutritional support in the treatment of these intoxications. Discussion: Nutrition in the treatment of acute corrosive intoxications is one of the most important therapeutic processes that largely contribute to faster recovery of the post-corrosive injuries of upper GIT, stabilization of biologic, immunologic and metabolic parameters, and reduction of length of stay in hospital Aim of the treatment of acute corrosive intoxications is to prevent perforation and progressive fibrosis, and esophageal and gastric stenosis. There are different and often conflicting positions, on the conservative treatment of acute corrosive intoxications in adults. Such treatment mainly consists of anti-secretory treatment, antibiotics and intensive hyper-alimentation, aiming to prevent late post-corrosive intoxications. Conclusion: It is considered that nutritional support plays a major role in maintenance of metabolic processes and prevention of severe metabolic complications that could additionally aggravate the condition and impair the treatment.

    This article presents the results of treatment of 54 patients with acute pancreatitis. The patients were divided into two groups according to the method of treatment. The control group (26 patients) received a conventional therapy, whereas the experimental group (28 patients) received mexidol in combination with the intravenous laser irradiation of blood. Clinical and laboratory tests confirmed a high efficiency of the combined therapy based on the administration of mexidol antioxidant and low-intensity (lambda) equals 0.63 micrometers diode laser irradiation of blood. This therapeutic technique produced an influence on the basic pathogenetic mechanisms of acute pancreatitis. The application of this method of treatment improved the course and prognosis of acute pancreatitis.

    Compartment syndrome of the thigh is a rare emergency often treated operatively. The purpose of this study was to evaluate the effects of nonoperative treatment for compartment syndrome of the thigh associated with acute renal failure after the 2008 Wenchuan earthquake. Nonoperative treatment, which primarily involves continuous renal replacement therapy, was performed in 6 patients (3 men and 3 women) who presented with compartment syndrome of the thigh associated with acute renal failure. The mean mangled extremity severity score (MESS) and laboratory data regarding renal function were analyzed before and after treatment, and the clinical outcome was evaluated at 17-month follow-up. Laboratory data regarding renal function showed improvements. All 6 patients survived with the affected lower limbs intact after nonoperative treatment. Follow-up revealed active knee range of motion and increased muscle strength, as well as a recovery of sensation. A positive linear correlation was found between MESS and the time required to achieve a reduction in swelling, as well as the time required for the recovery of sensation and knee range of motion (r>0.8; P<.05). Satisfactory clinical outcomes were obtained in patients with compartment syndrome of the thigh associated with acute renal failure.Urine alkalization, electrolyte and water balance, and continuous renal replacement therapy have played an important role in saving lives and extremities. Nonoperative treatment should be considered in the treatment of compartment syndrome of the thigh associated with acute renal failure. PMID:22495847

    Although there are high survival rates for children with acute lymphoblastic leukaemia, their outcome is often counterbalanced by the burden of toxic effects. This is because reported frequencies vary widely across studies, partly because of diverse definitions of toxic effects. Using the Delphi method, 15 international childhood acute lymphoblastic leukaemia study groups assessed acute lymphoblastic leukaemia protocols to address toxic effects that were to be considered by the Ponte di Legno working group. 14 acute toxic effects (hypersensitivity to asparaginase, hyperlipidaemia, osteonecrosis, asparaginase-associated pancreatitis, arterial hypertension, posterior reversible encephalopathy syndrome, seizures, depressed level of consciousness, methotrexate-related stroke-like syndrome, peripheral neuropathy, high-dose methotrexate-related nephrotoxicity, sinusoidal obstructive syndrome, thromboembolism, and Pneumocystis jirovecii pneumonia) that are serious but too rare to be addressed comprehensively within any single group, or are deemed to need consensus definitions for reliable incidence comparisons, were selected for assessment. Our results showed that none of the protocols addressed all 14 toxic effects, that no two protocols shared identical definitions of all toxic effects, and that no toxic effect definition was shared by all protocols. Using the Delphi method over three face-to-face plenary meetings, consensus definitions were obtained for all 14 toxic effects. In the overall assessment of outcome of acute lymphoblastic leukaemia treatment, these expert opinion-based definitions will allow reliable comparisons of frequencies and severities of acute toxic effects across treatment protocols, and facilitate international research on cause, guidelines for treatment adaptation, preventive strategies, and development of consensus algorithms for reporting on acute lymphoblastic leukaemia treatment.

    Posttraumatic osteoarthritis is caused by a cascade of pathobiologic and pathomechanical events starting with intraarticular fractures in the cartilage. Currently, treatment of fractures is completely focused on restoration of the macroanatomy of the joint. The premise is that restoring the macroanatomy will prevent ongoing stresses and in turn prevent cartilage degeneration. However, current treatment ignores acute mechanical damage sustained by cartilage at the time of injury. This study describes the initial development of a novel nanocomposite photopolymerizing copolymer that has potential to restore local structural integrity to acutely injured cartilage, and subsequently act as a carrier for chondrocyte-enhancing bioactive agents.

    Acute otitis media (AOM) is the most common bacterial infection in children and has a very varied clinical spectrum, ranging from spontaneous resolutions to serious complications. The effect of antibiotics in AOM depends on the chosen outcome, but has been shown to reduce pain somewhat, and have a greater beneficial effect in severe cases of AOM. Today, not all episodes of AOM are treated with antibiotics, but most countries have issued guidelines that include an option of watchful waiting in many cases. Prevention of AOM reaches from modification of environmental risk factors to vaccinations and surgery. Conjugate pneumococcal vaccines and influenza vaccines have been shown to somewhat reduce the number of AOM episodes in different groups of children. Grommets, with or without adenoidectomy, are effective at least during the first 6 months after surgery. PMID:25896748

    Adenosine receptors have been the target of intense research with respect to potential use of selective ligands in a variety of therapeutic areas. Caffeine and theophylline are adenosine receptor antagonists, and over the past three decades a wide range of selective agonists and antagonists for adenosine receptor subtypes have been developed. A complication to the therapeutic use of adenosine receptor ligands is the observation that the effects of acute administration of a particular ligand can be diametrically opposite to the chronic effects of the same ligand. This ‘effect inversion’ is discussed here by Ken Jecobson and colleagues, and has been observed for effects on cognitive processes, seizures and ischaemic damage. PMID:8936347

    Adult neurogenesis in the hippocampus is impaired in schizophrenic patients and in an animal model of schizophrenia. Amongst a plethora of regulators, the immune system has been shown repeatedly to strongly modulate neurogenesis under physiological and pathological conditions. It is well accepted, that schizophrenic patients have an aberrant peripheral immune status, which is also reflected in the animal model. The microglia as the intrinsic immune competent cells of the brain have recently come into focus as possible therapeutic targets in schizophrenia. We here used a maternal immune stimulation rodent model of schizophrenia in which polyinosinic-polycytidilic acid (Poly I:C) was injected into pregnant rats to mimic an anti-viral immune response. We identified microglia IL-1β and TNF-α increase constituting the factors correlating best with decreases in net-neurogenesis and impairment in pre-pulse inhibition of a startle response in the Poly I:C model. Treatment with the antibiotic minocycline (3mg/kg/day) normalized microglial cytokine production in the hippocampus and rescued neurogenesis and behavior. We could also show that enhanced microglial TNF-α and IL-1β production in the hippocampus was accompanied by a decrease in the pro-proliferative TNFR2 receptor expression on neuronal progenitor cells, which could be attenuated by minocycline. These findings strongly support the idea to use anti-inflammatory drugs to target microglia activation as an adjunctive therapy in schizophrenic patients.

Design Randomised, double blind, active comparator controlled trial. Setting 43 outpatient study centres in 11 countries. Participants 142 men and eight women (75 patients per treatment group) aged 18 years or over presenting with clinically diagnosed acute gout within 48 hours of onset. Interventions Etoricoxib 120 mg administered orally once daily versus indometacin 50 mg administered orally three times daily, both for 8 days Main outcome measures Patients' assessment of pain in the study joint over days 2 to 5 (primary end point); investigators' and patients' global assessments of response to treatment and tenderness of the study joint (key secondary end points). Results Etoricoxib showed efficacy comparable to indometacin. Patients' assessment of pain in the study joint (0-4 point Likert scale, “no pain” to “extreme pain”) over days 2 to 5 showed a least squares mean change from baseline of −1.72 (95% confidence interval −1.90 to −1.55) for etoricoxib and −1.83 (−2.01 to −1.65) for indometacin. The difference between treatment groups met prespecified comparability criteria. All other efficacy end points, including those reflecting reduction in inflammation and analgesia, provided corroborative evidence of comparable efficacy. Significant pain relief was evident at the first measurement, 4 hours after the first dose of treatment. Prespecified safety analyses revealed that drug related adverse experiences occurred significantly less frequently with etoricoxib (22.7%) than with indometacin (46.7%) (P=0.003), although overall adverse experience rates were similar between the two treatment groups. Conclusion Etoricoxib 120 mg once daily provides rapid and effective treatment for acute gouty arthritis comparable to indometacin 50 mg three times daily. Etoricoxib was generally

    Major ozonated autohemotherapy has been shown to promote recovery of upper limb motor function in patients with acute cerebral infarction, but whether major ozonated autohemotherapy affects remote injury remains poorly understood. Here, we assumed that major ozonated autohemotherapy contributes to recovery of clinical function, possibly by reducing remote injury after acute cerebral infarction. Sixty acute cerebral infarction patients aged 30-80 years were equally and randomly allocated to ozone treatment and control groups. Patients in the ozone treatment group received medical treatment and major ozonated autohemotherapy (47 mg/L, 100 mL ozone) for 10 ± 2 days. Patients in the control group received medical treatment only. National Institutes of Health Stroke Scale score, modified Rankin scale score, and reduced degree of fractional anisotropy values of brain magnetic resonance diffusion tensor imaging were remarkably decreased, brain function improved, clinical efficiency significantly increased, and no obvious adverse reactions detected in the ozone treatment group compared with the control group. These findings suggest that major ozonated autohemotherapy promotes recovery of neurological function in acute cerebral infarction patients by reducing remote injury, and additionally, exhibits high safety.

These findings suggest that major ozonated autohemotherapy promotes recovery of neurological function in acute cerebral infarction patients by reducing remote injury, and additionally, exhibits high safety.

  8. Early treatment of acute migraine: new evidence of benefits.

    PubMed

    Valade, D

    2009-12-01

    The current management approach to migraine headaches advocates use of triptan medications early in the course of an attack while pain is still mild, rather than waiting to treat the pain when it has progressed to moderate-severe. Recently, strong new evidence for the benefits of early intervention has become available. The AEGIS, AIMS and AwM studies of almotriptan in patients with migraine indicate that earlier treatment initiation and lower pain intensity at the time of treatment are important predictors of enhanced therapeutic outcomes. The opportunity to treat early exists for about 50% of all migraine attacks, which offers considerable scope for improving migraine management. Importantly, treating pain early and before it has progressed beyond 'mild' meets many of the expectations patients have of their migraine treatment. It is believed that consistent, positive outcomes may assist in overcoming the various physician- and patient-perceived barriers to adoption of this beneficial treatment strategy. PMID:20017750

    The outcome of patients with acute promyelocytic leukaemia (APL) has dramatically improved over the last two decades, due to the introduction of combined all-trans retinoic acid (ATRA) and chemotherapy regimens and, more recently, to the advent of arsenic trioxide (ATO). ATRA and anthracycline-based chemotherapy remains a widely used strategy, providing cure rates above 80%, but it is associated with risk of severe infections and occurrence of secondary leukaemias. ATO is the most effective single agent in APL and, used alone or in combination with ATRA or ATRA and reduced-intensity chemotherapy, results in greater efficacy with considerably less haematological toxicity. The toxic profile of ATO includes frequent, but manageable, QTc prolongation and increase of liver enzymes. Two large randomized studies have shown that ATRA + ATO is superior to ATRA + chemotherapy for newly diagnosed low-risk APL resulting in 2-4 year event-free survival rates above 90% and very few relapses. According to real world data, the spectacular progress in APL outcomes reported in clinical trials has not been paralleled by a significant improvement in early death rates, this remains the most challenging issue for the final cure of the disease.

    Acute iron intoxication is one of the leading causes of overdose morbidity and mortality in children. The toxicity of iron has been postulated to be related to free radical formation and subsequent lipid peroxidation. Hyperbaric oxygen treatment can result in a number of beneficial biochemical, cellular and physiological effects, and has recently been shown to induce cellular protection against ischaemia, and in some cases against free radical formation. In the current study, we aimed to investigate the effects of hyperbaric oxygen treatment on mortality in acute iron intoxication in rats. After iron administration, 57 animals were divided into two groups: a treatment group receiving hyperbaric oxygen treatment (n = 30) and a control group (n = 27), and followed for 48 hr for signs of severe intoxication. In the second part of the study, 21 animals were divided into a treatment group receiving hyperbaric oxygen treatment (n = 10) and a control group (n = 11), and markers of oxidative stress were evaluated. We showed a significant reduction in mortality in hyperbaric oxygen-treated animals from 17 of 27 (62.9%) among untreated rats to 6 of 30 (20%). Surprisingly, in the treatment group, levels of oxidative stress markers were higher. We postulate that hyperbaric oxygen has a potentially beneficial effect in acute iron intoxication.

    Mastitis is a benign infection of the breast if it is treated early. If two days elapse before treatment is started, it can lead to serious complications such as chronic or recurrent mastitis or breast abscess. Treatment consists in frequent nursing and massaging or stripping the breast to keep it empty of milk or pus, and appropriate antibiotics. Incision and drainage of a breast abscess can be done in the office under local anesthesia, and the drainage continued at home by the mother. PMID:21253250

    Neuroleptic malignant syndrome is a rare but potentially lethal, rare reaction to neuroleptics which is characterized by altered levels of consciousness, extrapyramidal effects, autonomic instability, hyperthermia, and elevated serum creatine phosphokinase levels. The most serious complication of neuroleptic malignant syndrome is acute renal failure. We investigated six cases of neuroleptic malignant syndrome associated with myoglobulinemic acute renal failure due to rhabdomyolysis and effect of hemodialysis or hemodiafiltration. The patients were five males and one female with a mean age of 43.5 yr. All of the patients, who developed acute renal failure induced from rhabdomyolysis, had previously received butyrophenone (haloperidol), phenothiazine, benzamide, iminomide, benzisoxazole, antidepressants, and hypnotics (benzodiazepine and barbiturate) for the treatment of schizophrenia. The clinical manifestations of neuroleptic malignant syndrome were characterized by altered consciousness, muscle rigidity and weakness, fever, and excessive perspiration. The peak laboratory data were blood urea nitrogen 102 +/- 26 (mean +/- SD) mg/dL, serum creatinine 9.1 +/- 2.1 mg/dL, serum creatine phosphokinase 229,720 +/- 289,940 IU/L, and all of them developed oliguric acute renal failure. Dantrolene sodium administration was given to five cases and hemodialysis or hemodiafiltration was performed in all of them. The serum creatinine level after hemodialysis or hemodiafiltration was 1.4 +/- 1.0 mg/dL. All patients were successfully cured of acute renal failure by hemodialysis or hemodiafiltration. As a result, myoglobulinemic acute renal failure associated with neuroleptic malignant syndrome was successfully treated by hemodialysis or hemodiafiltration.

    Sixty-eight patients who presented to the casualty ward with acute ankle joint injuries were studied to examine the effect of ibuprofen on pain and ankle swelling. Thirty-two patients were treated with placebo tablets and 36 with 600 mg ibuprofen tablets taken four times a day for 4 to 6 days. All of the patients were immobilized and requested to keep the foot elevated. The results showed that ibuprofen had no effect on the ankle swelling. The need for additional analgesics was not influenced by treatment with ibuprofen, which means that ibuprofen has no effect on pain. The time elapsed from occurrence of the injury to arrival at the casualty ward was negatively correlated to the reduction of ankle joint swelling during the treatment period. Treatment with ice-sprays, icebags, or cold water during the acute stage of injury did not influence the reduction of swelling during the treatment period. PMID:2675651

    Falanga, Anna; Russo, Laura; Tartari, Carmen J

    2011-01-01

    Acute promyelocytic leukemia (APL) is a distinct subtype of myeloid leukemia characterized by t(15;17) chromosomal translocation, which involves the retinoic acid receptor-alpha (RAR-alpha). APL typically presents with a life-threatening hemorrhagic diathesis. Before the introduction of all-trans retinoic acid (ATRA) for the cure of APL, fatal hemorrhages due, at least in part, to the APL-associated coagulopathy, were a major cause of induction remission failure. The laboratory abnormalities of blood coagulation found in these patients indicate the occurrence of a hypercoagulable state. Major determinants of the coagulopathy of APL are endogenous factors expressed by the leukemic cells, including procoagulant factors, fibrinolytic proteins, and non-specific proteolytic enzymes. In addition, these cells have an increased capacity to adhere to the vascular endothelium, and to secrete inflammatory cytokines [i.e. interleukin-1beta (IL-1beta) and tumor necrosis factor (TNF-alpha)], which in turn stimulate the expression of prothrombotic activities by endothelial cells and leukocytes. ATRA can interfere with each of the principal hemostatic properties of the leukemic cell, thus reducing the APL cell procoagulant potential, in parallel to the induction of cellular differentiation. This effect occurs in vivo, in the bone marrow of APL patients receiving ATRA, and is associated with the improvement of the bleeding symptoms. Therapy with arsenic trioxide (ATO) also beneficially affects coagulation in APL. However, early deaths from bleeding still remain a major problem in APL and further research is required in this field. In this review, we will summarize our current knowledge of the pathogenesis of the APL-associated coagulopathy and will overview the therapeutic approaches for the management of this complication.

    Introduction: The purpose of this study was to evaluate our experience with initial percutaneous transluminal angioplasty (PTA) {+-} stenting as valuable options in the acute setting. Methods: Between 2003 and 2008, eight patients with abdominal angio-MDCT-scan proven thrombotic AMI benefited from initial PTA {+-} stenting. We retrospectively assessed clinical and radiological findings and their management. Seven patients presented thrombosis of the superior mesenteric artery, and in one patient both mesenteric arteries were occluded. All patients underwent initial PTA and stenting, except one who had balloon PTA alone. One patient was treated by additional in situ thrombolysis. Results: Technical success was obtained in all patients. Three patients required subsequent surgery (37.5%), two of whom had severe radiological findings (pneumatosis intestinalis and/or portal venous gas). Two patients (25%) died: both had NIDD, an ASA score {>=}4, and severe radiologic findings. Satisfactory arterial patency was observed after a follow-up of 15 (range, 11-17) months in five patients who did not require subsequent surgery, four of whom had abdominal guarding but no severe CT scan findings. One patient had an ileocecal stenosis 60 days after the procedure. Conclusions: Initial PTA {+-} stenting is a valuable alternative to surgery for patients with thrombotic AMI even for those with clinical peritoneal irritation signs and/or severe radiologic findings. Early surgery is indicated if clinical condition does not improve after PTA. The decision of a subsequent surgery must be lead by early clinical status reevaluation. In case of underlying atherosclerotic lesion, stenting should be performed after initial balloon dilatation.

    Sunitinib is a multiple tyrosine kinase receptors inhibitor that is approved for the treatment of advanced renal cell carcinoma. Amongst its targets are fetal liver tyrosine kinase receptor 3 (FLT 3) and vascular endothelial growth factor receptor (VEGFR). Renal toxicity has not been reported from the trials, but several patients have been reported to develop a pre-eclampsia-like syndrome. We report the first case of acute tubular necrosis in a patient with multiple myeloma following treatment with sunitinib.

    The present study was designed to assess the anti-inflammatory activity of hyperbaric oxygen treatment by comparing it with that of diclofenac, a nonsteroidal anti-inflammatory drug, and also to investigate whether hyperbaric oxygen treatment enhances the anti-inflammatory effect of diclofenac in carrageenan-induced paw edema which is commonly employed as an acute inflammation model in rats. Hyperbaric oxygen treatment and diclofenac (20 mg/kg) markedly reduced the carrageenan-induced paw edema in rats. In other words, they displayed anti-inflammatory activity. On the other hand, hyperbaric oxygen treatment did not consistently modify the anti-inflammatory effect of diclofenac in this model.

    While the majority of children and adolescents with newly diagnosed childhood acute lymphoblastic leukemia (ALL) will be cured, as many as 20 % of patients will experience relapse. On current treatment regimens, the intensity of upfront treatment is stratified based upon prognostic factors with the aim of improving cure rates (for those at the highest risk of relapse) and minimizing treatment-related morbidity (for lower-risk patients). Here we review advances in the understanding of prognostic factors and their application. We also highlight novel treatment approaches aimed at improving outcomes in childhood ALL.

    The psychoanalytic understanding of suicide has greatly expanded in the past 30 years, and the older therapeutic approach has been modified. Although the turning of murder on the self inferred by Freud 90 years ago remains a cornerstone, current practice concentrates on the identification of a precipitating event, the escalation of intolerable painful affect that the patient cannot moderate, the self-perception of helplessness, the evolution of hopelessness as a secondary affect, increasing fantasies of suicide as a means of escape, and ego regression (self-deconstruction), leading progressively to suicide. Recent clinical research, advances in the study of cognition, and neurobiological studies have contributed to the reorientation and enrichment of the psychoanalytic perspective on suicide. The treatment of a university student who had fallen into a suicide crisis is discussed from the psychoanalytic point of view, and evidence for the efficacy of this treatment is reviewed.

    Treatment outcomes of pediatric cancers have improved greatly with the development of improved treatment protocols, new drugs, and better supportive measures, resulting in overall survival rates greater than 70%. Survival rates are highest in acute lymphoblastic leukemia, reaching more than 90%, owing to risk-based treatment through multicenter clinical trials and protocols developed to prevent central nervous system relapse and testicular relapse in boys. New drugs including clofarabine and nelarabine are currently being evaluated in clinical trials, and other targeted agents are continuously being developed. Chimeric antigen receptor-modified T cells are now attracting interest for the treatment of recurrent or refractory disease. Stem cell transplantation is still the most effective treatment for pediatric acute myeloid leukemia (AML). However, in order to reduce treatment-related death after stem cell transplantation, there is need for improved treatments. New drugs and targeted agents are also needed for improved outcome of AML. Surgery and radiation therapy have been the mainstay for brain tumor treatment. However, chemotherapy is becoming more important for patients who are not eligible for radiotherapy owing to age. Stem cell transplant as a means of high dose chemotherapy and stem cell rescue is a new treatment modality and is often repeated for improved survival. Drugs such as temozolomide are new chemotherapeutic options. In order to achieve 100% cure in children with pediatric cancer, every possible treatment modality and effort should be considered.

    Osteoporosis in adult life is associated with a significant morbidity and may be predisposed to by osteopenia and failure to reach peak bone mass in childhood. Children treated for acute lymphoblastic leukemia (ALL) may be at risk of osteopenia as a result of previous therapy or as a consequence of the disease process itself. Dual energy x-ray absorptiometry measurements of bone mineral content (BMC) for the whole body and at the lumbar spine and hip were taken in 35 (14 male) long-term survivors of ALL and compared with results in 20 (10 male) survivors of other malignancies and 31 (17 male) healthy sibling controls. The measured BMC was expressed as a percentage of a predicted value derived from the control group and based on the variables that had influence upon it. BMC (%) was reduced at the spine in the ALL group compared with controls [92.4 (8.0)% versus 100.4 (9.7)%, respectively; p < 0.005] and at the hip compared with both other malignancies and controls [89.0 (11.5)% versus 96.1 (11.7)% and 100.4 (9.2)%, respectively; p < 0.0005]. Increasing length of time off therapy was associated with a significant increase in %BMC at both the spine and the hip. For the spine, this association was significantly different between the ALL group and other malignancies, suggesting that any gain in %BMC after therapy was slower in children treated for ALL. Both exercise capacity and levels of physical activity were correlated with %BMC at the hip (r = 0.44, p < 0.001 and r = 0.29, p < 0.01, respectively). Previous exposure to methotrexate, ifosfamide, and bleomycin was associated with a reduction in %BMC at the spine. Exposure to 6-mercaptopurine and cisplatin was associated with a reduction at the hip. In conclusion, children treated for ALL are osteopenic. The mechanism is probably multifactorial but is partially related to previous chemotherapy, limited exercise capacity, and relative physical inactivity.

    Systemic antibiotic treatment has emerged as a powerful adjunct to conventional mechanical debridement for therapeutic management of the periodontal diseases. The conceptual basis for treating periodontal diseases as infections is particularly attractive in part because of substantial data indicating that these diseases may be associated with specific putative pathogens. Further, discrete groups of patients respond well to systemic antibiotics and exhibit improvement of clinical parameters, including attachment level and inflammation. This bacterial-host interaction, which is ever-so-present in periodontitis, directs us toward utilizing antimicrobial agents along with the routine mechanical debridement. This case report presents a case of a female patient with recurrence of the chronic generalized periodontitis with gingival enlargement, which is treated thrice by referral dentist. A through clinical examination was carried out pre-operatively and treatment was planned with systemic minocycline in conjunction with the conventional non-surgical approach. There was a significant reduction of pocket depth, gain in attachment with dramatic improvement clinically.

    A two-year-old girl had had fever for one week, and since the previous day general malaise, cutaneous pustolosis with swollen hands and feet. The skin condition had developed three days after the start of amoxicillin therapy. Laboratory tests at the time of admission indicated an infection. The diagnosis was 'acute generalised exanthematous pustulosis' (AGEP). During treatment with a soothing lotion, lasting one week, the patient improved and the skin condition disappeared. AGEP is characterised by acute onset of a pustular eruption in association with fever. It is usually seen after the use of drugs. This is an uncommon disease in children.

    Meat tenderizer containing the proteolytic enzyme papain was tested for therapeutic efficacy in the sting of the imported fire ant. The parameters of pain and itching were used to evaluate qualitatively the sting response in 22 healthy medical students, and the laser Doppler velocimeter was used to assess quantitatively the change in cutaneous blood flow. The results indicated that, during the acute-phase reaction, no clinically or statistically significant difference was found between stings treated with meat tenderizer and stings treated without tenderizer. Therefore we conclude that meat tenderizer is of no therapeutic value in the acute treatment of the imported fire ant sting.

    Background: Acute ischemic stroke caused by internal carotid artery (ICA) occlusion usually has a poor prognosis, especially the T occlusion cases without functional collaterals. The efficacy of intravenous (IV) or intra-arterial (IA) thrombolysis with recombinant tissue plasminogen activator (rt-PA) remains ambiguous in these patients. Eendovascular recanalization of the occluded carotid has been attempted in recent years as a potential strategy. However, the different etiologies of ICA occlusion pose a significant challenge to neurointerventionists. Recently, several endovascular evolvements have been reported in treating carotid occlusion-related stroke. This review summarizes the current status of treatment for acute ICA occlusion.

    Human experimental challenge studies with influenza virus infection and controlled intervention trials have demonstrated beyond doubt the role of influenza virus infection in the pathogenesis of acute otitis media. Influenza virus infections not only disrupt eustachian tube function, but also impair recovery from infection and facilitate attachment of bacterial pathogens to respiratory epithelial cells. Immunization of young children with either inactivated or live, attenuated influenza vaccine will significantly reduce the incidence of acute otitis media. Early treatment of influenza with antiviral medication will reduce eustachian tube dysfunction that results from influenza virus infection. Influenza produces high morbidity in children that could be averted by universal immunization with attenuated nasal spray vaccine.

    Background. There is an international epidemic of hepatitis C virus (HCV) infection among human immunodeficiency virus (HIV)–infected men who have sex with men. Sustained virologic response (SVR) rates with pegylated interferon and ribavirin treatment are higher in these men during acute HCV than during chronic HCV, but treatment is still lengthy and SVR rates are suboptimal. Methods. We performed a pilot study of combination therapy with telaprevir, pegylated interferon, and ribavirin in acute genotype 1 HCV infection in HIV-infected men. Men who were treated prior to the availability of, or ineligible for, telaprevir were the comparator group. The primary endpoint was SVR12, defined as an HCV viral load <5 IU/mL at least 12 weeks after completing treatment. Results. In the telaprevir group, 84% (16/19) of men achieved SVR12 vs 63% (30/48) in the comparator group. Among men with SVR, median time to undetectable viral load was week 2 in the telaprevir group vs week 4 in the comparator group, and 94% vs 53% had undetectable viral loads at week 4. Most patients (81%) who achieved SVR in the telaprevir group received ≤12 weeks of treatment and there were no relapses after treatment. The overall safety profile was similar to that known for telaprevir-based regimens. Conclusions. Incorporating telaprevir into treatment of acute genotype 1 HCV in HIV-infected men halved the treatment duration and increased the SVR rate. Larger studies should be done to confirm these findings. Clinicians should be alert to detect acute HCV infection of HIV-infected men to take advantage of this effective therapy and decrease further transmission in this epidemic. PMID:24336914

    Cough represents one of the most common reasons for pediatrician consultations. There are many available treatments for symptomatic relief, including honey. Despite its wide availability, there is little knowledge about its benefits. Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified three systematic reviews including three randomized trials. We combined the evidence using meta-analysis and generated a summary of findings table following the GRADE approach. We concluded the use of honey probably decreases the severity and frequency of cough, improves the quality of parent's and patient's sleep, and does not have side effects. PMID:27280298

    Regional analgesia, opioids, and several oral analgesics are commonly used for the treatment of acute pain after breast cancer surgery. While all of these treatments can suppress the acute postsurgical pain, there is growing evidence that suggests that the postsurgical comorbidity will differ in accordance with the type of analgesic used during the surgery. Our current study reviewed the effect of analgesics used for acute pain treatments on the major comorbidities that occur after breast cancer surgery. A considerable number of clinical studies have been performed to investigate the relationship between the acute analgesic regimen and common comorbidities, including inadequate quality of recovery after the surgery, persistent postsurgical pain, and cancer recurrence. Previous studies have shown that the choice of the analgesic modality does affect the postsurgical comorbidity. In general, the use of regional analgesics has a beneficial effect on the occurrence of comorbidity. In order to determine the best analgesic choice after breast cancer surgery, prospective studies that are based on a clear definition of the comorbidity state will need to be undertaken in the future.

    Triptans and analgetic nonsteroidal inflammatory drugs reduce acute pain syndromes in migraine. A further treatment option for an acute headache attack in patients with migraine may be the application of cyclooxygenase-2-specific inhibitors, as they have anti-inflammatory and analgesic properties. The objective of this pilot study was to investigate the effects of an oral fast-dissolving tablet of 10 mg of rizatriptan, an intravenous infusion of 40 mg of parecoxib, and a subcutaneous pen injection of sumatriptan (6 mg/0.5 mL) on pain relief in 3 cohorts of patients with episodic migraine. They were treated owing to the acute onset of a pain attack as a case of emergency. They were randomized to treatment with sumatriptan, rizatriptan, or parecoxib. The participants completed a visual analog scale for pain intensity at baseline before the drug administration and then after intervals of 20, 30, 60, and 120 minutes. Rizatriptan, parecoxib, and sumatriptan reduced pain symptoms. Twenty and 30 minutes after drug intake, rizatriptan was more efficacious than parecoxib and sumatriptan, and parecoxib was more effective than sumatriptan. Only a significant difference between rizatriptan and sumatriptan was found after 60 and 120 minutes. This trial demonstrates the effectiveness of a parecoxib infusion in the treatment of acute migraine and that the circumvention of the first pass effect of the liver by rizatriptan may be beneficial for fast pain relief.

    Acupuncture is an ancient medical treatment that is increasingly attracting the interest of the public. It is a complementary therapy that is widely used for management of pain, especially chronic discomfort caused by migraine, low-back pain and osteoarthritis of the knee(¹⁻³). The evidence base for the effectiveness of acupuncture and its clinical applications is controversial, and although its efficacy and safety in the management of acute pain have been demonstrated, the quality of this modality is still questionable. The present study reports a case of acute ankle injury, which was treated with acupuncture. A 33-year-old man presented with acute twisted ankle injury. He had pain with swelling around the ankle, and he was experiencing difficulty in walking. His clinical diagnosis was acute ankle sprain with severe pain. Several drug treatments are used for pain control, but in this case, we used acupuncture. After treatment, his pain diminished significantly with a decrease in VAS pain level from 8 to 4 in 20 minutes. At follow-up after one month, we found no skin infection in this case. PMID:27266242

    2012-01-01

    Objective Sulfur mustard (SM) is one of the major potent chemical warfare and attractive weapons for terrorists. It has caused deaths to hundreds of thousands of victims in World War I and more recently during the Iran-Iraq war (1980–1988). It has ability to develop severe acute and chronic damage to the respiratory tract, eyes and skin. Understanding the acute and chronic biologic consequences of SM exposure may be quite essential for developing efficient prophylactic/therapeutic measures. One of the systems majorly affected by SM is the respiratory tract that numerous clinical studies have detailed processes of injury, diagnosis and treatments of lung. The low mortality rate has been contributed to high prevalence of victims and high lifetime morbidity burden. However, there are no curative modalities available in such patients. In this review, we collected and discussed the related articles on the preventive and therapeutic approaches to SM-induced respiratory injury and summarized what is currently known about the management and therapeutic strategies of acute and long-term consequences of SM lung injuries. Method This review was done by reviewing all papers found by searching following key words sulfur mustard; lung; chronic; acute; COPD; treatment. Results Mustard lung has an ongoing pathological process and is active disorder even years after exposure to SM. Different drug classes have been studied, nevertheless there are no curative modalities for mustard lung. Conclusion Complementary studies on one hand regarding pharmacokinetic of drugs and molecular investigations are mandatory to obtain more effective treatments. PMID:23351279

    There have been major advances in our understanding of the multiple interactions between malignant cells and the innate and adaptive immune system. While the attention of immunologists has hitherto focused on solid tumors, the specific immunobiology of acute leukemias is now becoming defined. These discoveries have pointed the way to immune interventions building on the established graft-versus-leukemia (GVL) effect from hematopoietic stem-cell transplant (HSCT) and extending immunotherapy beyond HSCT to individuals with acute leukemia with a diversity of immune manipulations early in the course of the leukemia. At present, clinical results are in their infancy. In the coming years larger studies will better define the place of immunotherapy in the management of acute leukemias and lead to treatment approaches that combine conventional chemotherapy, immunotherapy and HSCT to achieve durable cures.

    PURPOSE The objective of this study was to assess the frequencies of ultrasound findings in patients with acute rotator cuff disorders in family medicine. METHODS In a prospective observational study, 129 patients aged 18 to 65 years with acute shoulder pain in whom the family physician suspected rotator cuff disease underwent ultrasound imaging. RESULTS Rotator cuff disease was present in 81% of the patients, and 50% of them had multiple disorders. Calcific tendonitis was the most frequently diagnosed specific disorder. An age of 40 years or older was most strongly related to rotator cuff disease. CONCLUSIONS Ultrasound imaging enables family physicians to rationalize treatment in nearly all patients who are aged 40 years and older with acute shoulder pain. PMID:25583893

    Small bowel obstruction (SBO) is a common clinical syndrome caused mainly by postoperative adhesions. In complement to clinical and biological evaluations, CT scan has emerged as a valuable imaging modality and may provide reliable information. The early recognition of signs suggesting bowel ischemia is essential for urgent operation. However appropriate management of SBO remains a common clinical challenge. Although a conservative approach can be successful in a substantial percentage of selected patients, regular and close re-assessement is mandatory. Any persistance or progression of the critical symptoms and signs should indeed lead to surgical exploration. Here we review the principles of adhesive SBO management and suggest a decision procedure for conservative versus surgical treatment.

    Studies of microbial pathogens and the toxins they produce are important for determining the mechanisms by which they cause disease and spread throughout a population. Some bacteria produce secretory enterotoxins (such as choleratoxin or the heat-labile or stable enterotoxins produced by E. coli) that invade cells directly. Others produce cytotoxins (such as those produced by Shigella, enteroinvasive E. coli, or C. difficile) that damage cells or trigger host responses that cause small or large bowel diseases (such as enteroaggregative or enteropathogenic E. coli or Salmonella). Viruses (such as noroviruses and rotaviruses) and protozoa (such as Cryptosporidium, Giardia or Entameba histolytica) disrupt cell functions and cause short- or long-term disease. Much epidemiological data about these pathogens have been collected from community- and hospital-acquired settings, as well from patients with traveler’s or persistent diarrhea. These studies have led to practical approaches for prevention, diagnosis and treatment. PMID:19457416

  6. A review of acute cyanide poisoning with a treatment update.

    PubMed

    Hamel, Jillian

    2011-02-01

    Cyanide causes intracellular hypoxia by reversibly binding to mitochondrial cytochrome oxidase a(3). Signs and symptoms of cyanide poisoning usually occur less than 1 minute after inhalation and within a few minutes after ingestion. Early manifestations include anxiety, headache, giddiness, inability to focus the eyes, and mydriasis. As hypoxia progresses, progressively lower levels of consciousness, seizures, and coma can occur. Skin may look normal or slightly ashen, and arterial oxygen saturation may be normal. Early respiratory signs include transient rapid and deep respirations. As poisoning progresses, hemodynamic status may become unstable. The key treatment is early administration of 1 of the 2 antidotes currently available in the United States: the well-known cyanide antidote kit and hydroxocobalamin. Hydroxocobalamin detoxifies cyanide by binding with it to form the renally excreted, non-toxic cyanocobalamin. Because it binds with cyanide without forming methemoglobin, hydroxocobalamin can be used to treat patients without compromising the oxygen-carrying capacity of hemoglobin.

    Compartment syndrome can be difficult to diagnose in a child, with delays in diagnosis leading to disastrous outcomes. Thirty-six cases of compartment syndrome in 33 pediatric patients were treated at the authors' institution from January 1, 1992, to December 31, 1997. There were 27 boys and 6 girls, with nearly equal upper and lower extremity involvement. Approximately 75% of these patients developed compartment syndrome in the setting of fracture. Pain, pallor, paresthesia, paralysis, and pulselessness were relatively unreliable signs and symptoms of compartment syndrome in these children. An increasing analgesia requirement in combination with other clinical signs, however, was a more sensitive indicator of compartment syndrome: all 10 patients with access to patient-controlled or nurse-administered analgesia during their initial evaluation demonstrated an increasing requirement for pain medication. With early diagnosis and expeditious treatment, >90% of the patients studied achieved full restoration of function.

    Transplantation of neural stem cells (NSCs) offers a novel therapeutic strategy for stroke; however, massive grafted-cell death following transplantation, possibly due to a hostile host-brain environment, lessens the effectiveness of this approach. Here, we have investigated whether reprogramming NSCs with minocycline, a broadly-used antibiotic also known to possess cytoprotective properties, enhances survival of grafted cells and promotes neuroprotection in ischemic stroke. NSCs harvested from the subventricular zone of fetal rats were preconditioned with minocycline in vitro and transplanted into rat brains 6 h after transient middle cerebral artery occlusion. Histological and behavioral tests were examined from days 0–28 after stroke. For in vitro experiments, NSCs were subjected to oxygen-glucose deprivation and reoxygenation. Cell viability and antioxidant gene expression were analyzed. Minocycline preconditioning protected the grafted NSCs from ischemic reperfusion injury via up-regulation of Nrf2 and Nrf2-regulated antioxidant genes. Additionally, preconditioning with minocycline induced the NSCs to release paracrine factors, including brain-derived neurotrophic factor, nerve growth factor, glial cell-derived neurotrophic factor, and vascular endothelial growth factor. Moreover, transplantation of the minocycline-preconditioned NSCs significantly attenuated infarct size and improved neurological performance, compared with non-preconditioned NSCs. Minocycline-induced neuroprotection was abolished by transfecting the NSCs with Nrf2-small interfering RNA before transplantation. Thus, preconditioning with minocycline, which reprograms NSCs to tolerate oxidative stress after ischemic reperfusion injury and to express higher levels of paracrine factors through Nrf2 up-regulation, is a simple and safe approach to enhance the effectiveness of transplantation therapy in ischemic stroke.

    Background: Research continues to develop novel therapeutic modalities that particularly focus on the pathogenesis of acute pancreatitis. This study aimed to assess the effects of diclofenac sodium and octreotide, alone or in combination, on pancreatic enzymes, pancreatic myeloperoxidase activity, histopathology and apoptosis of pancreas cells, using a model of experimentally induced acute pancreatitis. Objectives: We aimed to demonstrate effects of diclofenac sodium, octreotide and their combined use on pancreatic enzymes, activity of pancreatic myeloperoxidase (MPO) activity, histopathology and apoptosis of pancreas on treatment of caerulin-induced experimental acute pancreatitis. Materials and methods: Caerulin-induced acute pancreatitis model was created using a total of 58 male BALB-C mice of 25 gr in seven groups. Serum amylase, lipase levels and pancreatic myeloperoxidase activity were examined as well as apoptotic values in pancreatic acinar cells through TUNNEL method. Histopathology of pancreas was evaluated for presence of edema, hemorrhage, parenchymal necrosis, fat necrosis, leukocyte infiltration, and fibrosis. Results: In the diclofenac sodium group, apoptotic values in the pancreatic acinar cells were found to be statistically lower than in the acute pancreatitis group in terms of parenchymal necrosis and hemorrhage scores (P = 0.007, P = 0.002, and P = 0.052, respectively). No statistically significant differences were found in serum level of amylase, lipase, pancreatic myeloperoxidase activity and the other histopathological scores (P > 0.05). Conclusion: Diclofenac sodium, a cost-effective agent with a favorable side-effect profile, may represent a novel therapeutic agent for the treatment of acute pancreatitis. Findings of this study suggest a better efficacy for diclofenac sodium monotherapy as compared to octreotide alone or octreotide/diclofenac combination. PMID:26770346

    The true pathophysiologic nature of Peyronie's disease continues to evolve. This pathology often results in a penile plaque(s), penile deformity, curvature, pain, and erectile dysfunction. Clinically, there are two distinct phases, acute and chronic. The focus of this review will center on the management of the acute phase of Peyronie's disease. While little data exists demonstrating disease resolution, disease stabilization is an important clinical goal for patients as this often allows acceptable sexual function. Thus, medical management during the acute phase of Peyronie's disease is aimed at limiting and stabilizing the degree of penile fibrosis, decreasing penile curvature, and reducing penile pain. In this manuscript we explain different therapies; oral, topical, intralesional injection and others like extracorporeal shockwave (ESWT), radiation and penile traction for acute phase of Peyronie's disease. Although no consensus exists for the treatment of acute phase Peyronie's disease, a majority of patients can achieve stabilization and in some cases regression of their disease with proper medical therapy. The goals of therapy should be discussed extensively with each patient, noting that erectile function will be likely despite some degree of curvature.

  11. Treatment of Acute Low Pressure Pulmonary Edema in Dogs

    1981-01-01

    Severe pulmonary edema sometimes develops despite normal pulmonary capillary wedge pressure (Ppw). The equation describing net transvascular flux of lung liquid predicts decreased edema when hydrostatic pressure is reduced or when colloid osmotic pressure is increased in the pulmonary vessels. We tested these predictions in a model of pulmonary capillary leak produced in 35 dogs by intravenous oleic acid. 1 h later, the dogs were divided into five equal groups and treated for 4 h in different ways: (a) not treated, to serve as the control group (Ppw = 11.1 mm Hg); (b) given albumin to increase colloid osmotic pressure by 5 mm Hg (Ppw = 10.6 mm Hg); (c) ventilated with 10 cm H2O positive end-expiratory pressure (Peep) (transmural Ppw = 10.4 mm Hg); (d) phlebotomized to reduce Ppw to 6 mm Hg; (e) infused with nitroprusside, which also reduced Ppw to 6 mm Hg. Phlebotomy and nitroprusside reduced the edema in excised lungs by 50% (P< 0.001), but Peep and albumin did not affect the edema. Pulmonary shunt decreased on Peep and increased on nitroprusside, and lung compliance was not different among the treatment groups, demonstrating that these variables are poor indicators of changes in edema. Cardiac output decreased during the treatment period in all but the nitroprusside group, where Ppw decreased and cardiac output did not. We conclude that canine oleic acid pulmonary edema is reduced by small reductions in hydrostatic pressure, but not by increased colloid osmotic pressure, because the vascular permeability to liquid and protein is increased. These results suggest that low pressure pulmonary edema may be reduced by seeking the lowest Ppw consistent with adequate cardiac output enhanced by vasoactive agents like nitroprusside. Further, colloid infusions and Peep are not helpful in reducing edema, so they may be used in the lowest amount that provides adequate circulating volume and arterial O2 saturation on nontoxic inspired O2.

    Crises from the child and adolescent psychiatric point of view must be considered as unique or repeated moments of basic questioning of self-focused and relational perception. Hospitalisation if necessary depends on a well prepared social, legal, physical and cooperative framework. Patients, their family or social environment are in need of clarity, structure, and a professional counterpart willing to engage responsibly within an inpatient or--mostly--outpatient framework. He must adapt his diagnostic or therapeutic action to the patient's experience of fear, loss of orientation and insecurity. Then a crisis may be experienced like a bonding experience. Concerning the capacity of action confronted to psychiatric crisis the authors stress the importance of the scenic understanding, expressed symptoms and the acted-out crisis dynamics more than diagnostic classification. The diagnostic and decisive process of atunement to the patient in crisis is being described. A model for psychodynamic understanding of perception of and action towards crisis is proposed, which allows describing the interference between relational dynamics and intra-psychic conflicts leading to crisis. This can then be used as therapeutical focus for the crisis intervention or a consecutive psychotherapeutic treatment.

    Coupled plasma filtration adsorption (CPFA) is an extracorporeal blood purification therapy based on non-specific pro- and anti-inflammatory mediator adsorption on a special resin cartridge coupled with continuous veno-venous haemofiltration or continuous veno-venous haemodiafiltration and is one of the emerging treatments for septic patients. However, in the literature, there are limited data about its efficacy in treating patients with acute diseases but without the traditional criteria for sepsis. We describe the case of a 43-year-old male who developed acute respiratory distress syndrome secondary to pneumonia and acute kidney injury, whose clinical conditions rapidly improved after early CPFA therapy.

    2014-03-01

    Diabetes, chronic obstructive pulmonary disease (COPD) and anemia are comorbidities with a high prevalence and impact in heart failure (HF). The presence of these comorbidities considerably worsens the prognosis of HF. Diabetic patients have a higher likelihood of developing symptoms of HF and both the treatment of diabetes and that of acute HF are altered by the coexistence of both entities. The glycemic targets in patients with acute HF are not well-defined, but could show a U-shaped relationship. Stress hyperglycemia in non-diabetic patients with HF could also have a deleterious effect on the medium-term prognosis. The inter-relationship between COPD and HF hampers diagnosis due to the overlap between the symptoms and signs of both entities and complementary investigations. The treatment of acute HF is also altered by the presence of COPD. Anemia is highly prevalent and is often the direct cause of decompensated HF, the most common cause being iron deficiency anemia. Iron replacement therapy, specifically intravenous forms, has helped to improve the prognosis of acute HF.

    Purpose: To assess the feasibility and effectiveness of emergency endovascular treatment of acute arterial injuries after orthopedic surgery. Materials and Methods: Fifteen patients (mean age 68.3 years) with acute arterial injuries after orthopedic surgery were observed, in particular, 5 patients with pseudoaneurysm, 9 patients with active bleeding, and 1 patient with arterial dissection. Transarterial embolization (TAE) and positioning of covered and noncovered stents were the treatments performed. Follow-up after stent implantation (mean 36 months) was performed with color Doppler US (CDU) at 1, 3, 6, and 12 months and yearly thereafter. Plain X-ray was performed to evidence dislodgment or fracture of the graft. A minimum of 12 months' follow-up is available after TAE. Results: Immediate technical success was obtained in all cases. No major complications occurred. Overall clinical success rate was 100%. During mean follow-up, stent-graft occlusions did not occurred. No recurrence and/or consequence of TAE was registered during a minimum follow-up of 12 months. Conclusions: Percutaneous treatment is a feasible and safe tool for treating arterial injuries because it can provide fast and definitive resolution of the damage. This low-invasiveness approach can be proposed as first-line treatment in patients with acute injuries after orthopedic surgery.

    We performed a meta-analysis for systematic evaluation of the status quo of catheter thrombolysis for the treatment of acute lower limb deep vein thrombosis in China. We searched the China Biomedical bibliographic database (CBM), China National Knowledge Infrastructure (CNKI), Weipu full-text electronic journals, Wanfang full-text database, and Medline (1990 through June 2011) for clinical randomized controlled trials of catheter-directed thrombolysis and superficial venous thrombolysis to compare their efficacies for the treatment of acute deep vein thrombosis. The results were analyzed by using the Cochrane-recommended RevMan 4.2 software package, and the odds ratio (OR) was used as the combined measure of efficacy. The search retrieved 8 randomized controlled trials, and meta-analysis using the total rate of effective treatment as the clinical observation index found that the combined OR for the catheter thrombolysis group versus the superficial venous thrombolysis group was significant (P < 0.01; OR = 11.78; 95% confidence interval = 6.99-19.87). In conclusion, the meta-analysis indicated that catheter thrombolysis was more effective than superficial venous thrombolysis for the treatment of acute deep vein thrombosis in the lower limb in Chinese individuals. However, the included trials were only of medium quality, so more rational and scientific clinical trials are needed to validate this conclusion.

    In the past months significant new data have been published in the field of headache and migraine. With the publication of the second and revised version of the classification of headache disorders, new entities such as chronic migraine have been introduced. Moreover, the repertoire of drugs available for the treatment of migraine has changed as well. Whereas ergot derivatives have been almost completely taken off the market, seven triptans in 23 different preparations are now available and allow the physician to customize the treatment of acute attacks. CGRP antagonists, a completely new generation of anti-migraine compounds for the treatment of acute attacks, have now been tested successfully in clinical trials. For the prophylaxis of migraine, several agents that had been well established for decades have recently been taken off the market too, but new agents such as topiramate, which possesses different modes of action, have been tested successfully and are now available for the prophylaxis of migraine. The following review will summarize the newest developments in acute therapy and prophylactic treatment of migraine.

  19. Minocycline corrects early, pre-plaque neuroinflammation and inhibits BACE-1 in a transgenic model of Alzheimer's disease-like amyloid pathology

    PubMed Central

    2012-01-01

    Background A growing body of evidence indicates that inflammation is one of the earliest neuropathological events in Alzheimer's disease. Accordingly, we have recently shown the occurrence of an early, pro-inflammatory reaction in the hippocampus of young, three-month-old transgenic McGill-Thy1-APP mice in the absence of amyloid plaques but associated with intracellular accumulation of amyloid beta petide oligomers. The role of such a pro-inflammatory process in the progression of the pathology remained to be elucidated. Methods and results To clarify this we administered minocycline, a tetracyclic derivative with anti-inflammatory and neuroprotective properties, to young, pre-plaque McGill-Thy1-APP mice for one month. The treatment ended at the age of three months, when the mice were still devoid of plaques. Minocycline treatment corrected the up-regulation of inducible nitric oxide synthase and cyclooxygenase-2 observed in young transgenic placebo mice. Furthermore, the down-regulation of inflammatory markers correlated with a reduction in amyloid precursor protein levels and amyloid precursor protein-related products. Beta-site amyloid precursor protein cleaving enzyme 1 activity and levels were found to be up-regulated in transgenic placebo mice, while minocycline treatment restored these levels to normality. The anti-inflammatory and beta-secretase 1 effects could be partly explained by the inhibition of the nuclear factor kappa B pathway. Conclusions Our study suggests that the pharmacological modulation of neuroinflammation might represent a promising approach for preventing or delaying the development of Alzheimer's disease neuropathology at its initial, pre-clinical stages. The results open new vistas to the interplay between inflammation and amyloid pathology. PMID:22472085

    The acute phase of venous thromboembolism (VTE) treatment focuses on the prompt and safe initiation of full-dose anticoagulation to decrease morbidity and mortality. Immediate management consists of resuscitation, supportive care, and thrombolysis for patients with haemodynamically significant pulmonary embolism (PE) or limb-threatening deep-vein thrombosis (DVT). Patients with contraindications to anticoagulants are considered for vena cava filters. Disposition for the acute treatment of VTE is then considered based on published risk scores and the patient's social status, as the first seven days carries the highest risk for VTE recurrence, extension and bleeding due to anticoagulation. Next, a review of: immediate and long-term bleeding risk, comorbidities (i. e. active cancer, renal failure, obesity, thrombophilia), medications, patient preference, VTE location and potential for pregnancy should be undertaken. This will help determine the most suitable anticoagulant for immediate treatment. The non-vitamin K antagonist oral anticoagulants (NOACs), including the factor Xa inhibitors apixaban, edoxaban and rivaroxaban as well as the direct-thrombin inhibitor dabigatran, are increasing the convenience of and options available for VTE treatment. Current options for immediate treatment include low-molecular-weight heparin (LMWH), unfractionated heparin (UFH), fondaparinux, apixaban, or rivaroxaban. LMWH or UFH may be continued as monotherapy or transitioned to treatment with a VKA, dabigatran or edoxaban. This review describes the upfront treatment of VTE and the evolving role of NOACs in the contemporary management of VTE.

    The study aims to provide an updated assessment of the evidence for individual pharmacological therapies for acute migraine treatment. Pharmacological therapy is frequently required for acutely treating migraine attacks. The American Academy of Neurology Guidelines published in 2000 summarized the available evidence relating to the efficacy of acute migraine medications. This review, conducted by the members of the Guidelines Section of the American Headache Society, is an updated assessment of evidence for the migraine acute medications. A standardized literature search was performed to identify articles related to acute migraine treatment that were published between 1998 and 2013. The American Academy of Neurology Guidelines Development procedures were followed. Two authors reviewed each abstract resulting from the search and determined whether the full manuscript qualified for review. Two reviewers studied each qualifying full manuscript for its level of evidence. Level A evidence requires at least 2 Class I studies, and Level B evidence requires 1 Class I or 2 Class II studies. The specific medications - triptans (almotriptan, eletriptan, frovatriptan, naratriptan, rizatriptan, sumatriptan [oral, nasal spray, injectable, transcutaneous patch], zolmitriptan [oral and nasal spray]) and dihydroergotamine (nasal spray, inhaler) are effective (Level A). Ergotamine and other forms of dihydroergotamine are probably effective (Level B). Effective nonspecific medications include acetaminophen, nonsteroidal anti-inflammatory drugs (aspirin, diclofenac, ibuprofen, and naproxen), opioids (butorphanol nasal spray), sumatriptan/naproxen, and the combination of acetaminophen/aspirin/caffeine (Level A). Ketoprofen, intravenous and intramuscular ketorolac, flurbiprofen, intravenous magnesium (in migraine with aura), and the combination of isometheptene compounds, codeine/acetaminophen and tramadol/acetaminophen are probably effective (Level B).

    Treatments for acute distal radioulnar joint (DRUJ) instability with distal radius fracture vary from conservative to operative treatment, although it seems to be no consensus regarding which treatment is optimal. This prospective randomized study was designed to compare the clinical outcomes for operative and conservative treatment of acute DRUJ instability with distal radius fracture, according to the presence or absence and type of ulnar styloid process fracture and the degree of its displacement. Between July 2008 and February 2013, we enrolled 157 patients who exhibited an unstable DRUJ during intraoperative manual stress testing (via the ballottement test) after fixation of the distal radius. Patients were classified according to the type of the ulnar styloid process fracture, using preoperative wrist radiography, and each group was divided into subgroups, according to their treatment method. We then compared the clinical outcomes between the conservative and operative treatments, using their range of motion; Disabilities of the Arm, Shoulder, and Hand score; modified Mayo wrist score; and grip strength. At 3 months after surgery, among patients without ulnar styloid process fracture, the flexion-extension range was 79 ± 15° after supination sugar-tong splinting (group A-1), 91 ± 14° after DRUJ transfixation (group A-2), and 89 ± 10° after arthroscopic triangular fibrocartilage complex repair (group A-3); the operative treatments provided greater joint motion ranges than conservative treatment. The groups with ulnar styloid process fractures at the tip (group B) or base (group C) also exhibited better clinical outcomes after the operative treatments, compared with after the conservative treatment. However, at the final follow-up, groups A-1, A-2, and A-3 exhibited similar flexion-extension ranges (122 ± 25°, 119° ± 18°, and 120° ± 16°, respectively) and modified Mayo wrist scores (87 ± 7, 89 ± 8, and 85 ± 9).

    Endoscopic biliary drainage has been established to provide effective treatment for acute obstructive jaundice and cholangitis. A recently developed ultrathin transnasal videoendoscope (TNE) is minimally invasive even for critically ill patients and can be performed without conscious sedation. Transnasal endoscopic biliary drainage (TNE-BD) is performed using a front-viewing TNE with approximately 5 mm outer diameter and 2 mm working channel diameter. Finally, 5F naso-biliary tube or plastic stent are placed. Technical success rates are approximately 100% and 70% for post-endoscopic sphincterotomy or placement of self-expandable metallic stent, and intact papilla, respectively. There are no serious complications. In conclusion, although further cases should be accumulated, TNE-BD and in particular, one-step naso-biliary drainage using TNE may be a useful and novel technique for the treatment of acute cholangitis.

    Essential oils are volatile and can have good antimicrobial activity. We compared the effects of oil of basil (Ocimum basilicum) and essential oil components (thymol, carvacrol, and salicylaldehyde) to those of a placebo when placed in the ear canal of rats with experimental acute otitis media caused by pneumococci or Haemophilus influenzae. Progress was monitored by otomicroscopic examination and middle ear cultures. The treatment with oil of basil or essential oil components cured or healed 56%-81% of rats infected with H. influenzae and 6%-75% of rats infected with pneumococci, compared with 5.6%-6% of rats in the placebo group. Essential oils or their components placed in the ear canal can provide effective treatment of acute otitis media. PMID:15871121

    Chondral and osteochondral fractures of the lower extremities are important injuries because they can cause pain and dysfunction and often lead to osteoarthritis. These injuries can be misdiagnosed initially which may impact on the healing potential and result in poor long-term outcome. This comprehensive review focuses on current pitfalls in diagnosing acute osteochondral lesions, potential investigative techniques to minimize diagnostic errors as well as surgical treatment options. Acute osteochondral fractures are frequently missed and can be identified more accurately with specific imaging techniques. A number of different methods can be used to fix these fractures but attention to early diagnosis is required to limit progression to osteoarthritis. These fractures are common with joint injuries and early diagnosis and treatment should lead to improved long term outcomes. PMID:26587063

    Two men aged 19 and 21 years ingested 1 g and 4 g respectively from 3 kg of a white crystalline powder that they thought was a substance of abuse. It was later identified as almost pure arsenic trioxide. Both had nausea and vomiting and one developed acute renal failure. Each was treated with 2,3-dimercaptopropanesulphonate (DMPS), and made a full recovery with no evidence of prolonged renal or neurological impairment. The DMPS-arsenic complex is probably associated with lower penetration into the CNS and as a consequence treatment with DMPS may result in lower acute and chronic neurotoxicity than treatment with the currently standard recommended chelating agent dimercaprol (British Anti-Lewisite; BAL).

    Relapse of acute lymphoblastic leukemia remains a major cause of death in patients following allogeneic hematopoietic stem cell transplantation. Several factors may affect the concurrence and outcome of relapse, which include graft-versus-host disease, minimal residual disease or intrinsic factors of the disease, and transplantation characteristics. The mainstay of relapse prevention and treatment is donor leukocyte infusions, targeted therapies, second transplantation, and other novel therapies. In this review, we mainly focus on addressing the impact of graft-versus-host disease on relapse and the prophylaxis and treatment of acute lymphoblastic leukemia relapse following allogeneic hematopoietic stem cell transplantation. We also make recommendations for critical strategies to prevent relapse after transplantation and challenges that must be addressed to ensure success. PMID:25709473

    The efficiency of a new peptide medicine-Prostatilen was studied when using it in acute postoperative retention of urine. Under observation there were 87 patients of 23-78 years of age after hemorrhoidectomy, plasty of the rectal sphincter or dissection of its fissure etc. The patients endured the treatment with Prostatilen well. Self-dependent urination was recovered during the nearest 40 min after injection of 5 mg of the medicine. In the treatment of 23 patients it was used prophylactically before the appearance of a micturate urge. In 14 of them the postoperative period was smooth, in 9 patients the self-dependent urination was recovered following one additional injection. Clinical observations confirm that Proctatilen has a regulating effect upon the bladder tone which allows it to be recommended as a medicine for prevention of acute reflex retention of urine after operations in the area of the rectal sphincter.

    To provide guidance to clinicians about best practices, the Wilderness Medical Society convened an expert panel to develop evidence-based guidelines for prevention and treatment of acute mountain sickness, high altitude cerebral edema, and high altitude pulmonary edema. These guidelines present the main prophylactic and therapeutic modalities for each disorder and provide recommendations about their role in disease management. Recommendations are graded based on the quality of supporting evidence and balance between the benefits and risks/burdens according to criteria put forth by the American College of Chest Physicians. The guidelines also provide suggested approaches to prevention and management of each disorder that incorporate these recommendations.

    It has been consistently observed that patients with renal dysfunction have more premature, severe, complicated, and fatal cardiovascular disease than age- and sex-matched individuals with normal renal function. There have been 4 major explanations for this finding: (1) positive confounding by third variables associated with chronic kidney disease (CKD), including diabetes mellitus and hypertension; (2) therapeutic nihilism or lesser use of beneficial therapies in CKD; (3) greater toxicities of therapies, such as bleeding from anticoagulants or contrast-induced kidney injury; (4) biological factors which result directly from CKD that work to promote and accelerate cardiovascular disease. In this paper, we focus on the issue of treatment disparities or therapeutic nihilism and its contribution to poor outcomes in the setting of acute coronary syndromes and acutely decompensated heart failure. This issue is important because if we can overcome barriers to the utilization of beneficial treatments, then clinical outcomes should improve over time.

    The aims of our experiments on animals were (i) to evaluate by direct oximery the efficiency of various antioxidant drugs in a complex treatment of acute pancreatitis and (ii) to determine the diagnostic value of the direct oximetry method for estimation of the efficiency of medical treatment. The article presents data obtained in a group 75 outbred Guinea with a model acute pancreatitis, which were treated with mexibel (group 1), emoxipin (group 2), end cytoflavin (group 3), with subsequent investigation of the pancreatic tissues by the direct oximetry method. The obtained results confirmed that the intraperitoneal injection of cytoflavin to animals stimulates tissue respiration, improves metabolism, promotes pancreas recovery, and also improves the prognosis and reduces the lethal outcome. The efficiency of cytoflavin within the complex therapy exceeds the effect of other antioxidants (mexibel and emoxipin) under otherwise equal conditions.

    2013-01-01

    Introduction Acute leukemia is rare in pregnancy. The importance of promptly diagnosing and treating this disease in pregnancy stems from its life-threatening potential, both to the mother and fetus. Case presentation We report a case of relapse of acute myeloid leukemia at 23 weeks of pregnancy in a 24-year-old Albanian woman. Our patient categorically refused chemotherapy treatment, and in her 35th week of gestation, severe hemorrhagic diathesis rapidly developed. The manifestation and course of this life-threatening complication posed therapeutic challenges for the attending medical team. Conclusion Based both on our experience and the results of other gynecological studies, there exists a strong indication that the earlier a patient’s chemotherapy treatment begins, the better the maternal outcome. We support chemotherapy for patients who are pregnant presenting with such illness. The present case report testifies that refusal of chemotherapy by such patients is a high-risk decision.

    Amoxicillin is a first-line antibiotic treatment for acute otitis media in children and one of the most commonly used antibiotics for human bacterial infections. We investigated changes in salivary bacterial communities among children treated with amoxicillin for acute otitis media (n = 18), using a culture-independent approach based on pyrosequencing of the V3 region of the bacterial 16S rRNA gene. The control group consisted of children with acute otitis media who were not given antibiotics (n = 15). One species-level phylotype assigned to the genus Streptococcus was identified across all (n = 99) saliva samples. Two additional species-level phylotypes from the genera Gemella and Granulicatella were shared by all (n = 45) samples of control subjects. Amoxicillin treatment resulted in reduced species richness and diversity, and a significant shift in the relative abundance of 35 taxa at different ranks from phylum to species-level phylotype. At the phylum level, prevalence of TM7 and Actinobacteria decreased at the end of treatment, whereas Proteobacteria had a higher relative abundance post-treatment. Multivariate analysis showed that samples from the same control subject taken over time intervals tended to cluster together. Among antibiotic-treated subjects, samples taken before and at the end of amoxicillin treatment formed two relatively well-separated clusters both of which greatly overlapped with samples taken about 3 weeks post-treatment. Our results point to a substantial but incomplete recovery of the salivary bacterial community from the antibiotic about 3 weeks after the end of treatment.

    The development and introduction of new antibiotics has, unfortunately, not kept pace with the development of bacterial resistance, and the need for new agents is becoming acute. Although some currently marketed agents remain valuable tools in the treatment of infectious diseases, few new drugs have reached the market in the last decade. In recent years, antibiotics with activity against certain problematic resistant bacteria such as methicillin-resistant Staphylococcus aureus, including linezolid and daptomycin, have been approved for clinical practice. Recently, tigecycline, a minocycline derivative, received approval by the United States Food and Drug Administration for treatment of complicated skin and skin structure and intraabdominal infections; the agent is also active against a variety of multidrug-resistant bacteria. Of the other agents in phase III development, ceftobiprole--a cephalosporin, and faropenem and doripenem--both carbapenems, have wide antibacterial spectra. Antimicrobial agents in the pipeline with marked gram-positive activity include dalbavancin, telavancin, and oritavancin. PMID:16178676

    Stress alters physiology and behavior across species. Most research on the effects of stress on behavior uses chronic stressors, and most are correlational. The effects of acute stressors on physiology and behavior have been mixed. Here, we use zebra finches, a highly gregarious species that forms long-term pair bonds, to test the effects of an acute corticosterone (CORT) on opposite-sex partner preferences over a same-sex individual or a group (the latter is a highly appealing option). We had two competing hypotheses. First, we predicted that acute CORT would alter preferences for the opposite sex bird in both conditions in both sexes. However, since there is a sex difference in the effects of CORT on partner preferences in voles, these effects may be more pronounced in males than in females. To test our hypotheses, we administered 2 doses of CORT (10μg and 20μg) or vehicle (control) using a repeated measures design. In the male vs. female test, there was a significant Sex by Treatment interaction, such that in males, 10μg CORT increased preferences for a female over the male compared to when these same males were treated with saline at baseline. There were no effects of treatment in females. In the opposite-sex vs. group condition, there was an overall effect of Treatment, such that the 10μg dose increased preference for the opposite-sex individual over both saline treatments, regardless of sex. These findings further our understanding of the effects of an acute stressor on sexual partner preferences.

  1. Role of somatostatin and its analogues in the treatment of acute and chronic pancreatitis.

    Acute pancreatitis is caused by the activation of digestive enzymes in the pancreas and a possible treatment, therefore, is the inhibition of enzyme secretion. This approach is somewhat controversial, however, as it is not clear whether pancreatic secretion continues to occur during the course of acute pancreatitis. Animal studies show an appreciable reduction of secretion in the inflamed pancreas, but studies in humans are not conclusive. The use of somatostatin or its analogue, octreotide, has been investigated in several clinical studies. A meta analysis of six individual studies in which somatostatin was given for acute pancreatitis showed that somatostatin significantly reduces mortality. A trial in patients with moderate to severe acute pancreatitis showed a lower rate (although not statistically significant) of complications in patients treated with 3 x 200 and 3 x 500 micrograms/day octreotide, compared with controls and patients receiving a lower dose of octreotide. A further study showed a significant reduction in patient controlled analgesics in patients treated with octreotide compared with controls. Pain is the important clinical symptom of chronic pancreatitis, possibly resulting from an increased intraductal pressure during secretion. The effect on pain of the inhibition of pancreatic secretion by octreotide has been investigated in two studies. One showed no significant reduction in pain after treatment with octreotide for three days. In the other, in which octreotide was used for three weeks, significantly less pain and analgesic use was recorded during octreotide treatment than during placebo. The most common complication of chronic pancreatitis is the formation of pseudocysts. There is some evidence that octreotide may be useful in their treatment. PMID:7911442

    Background Few studies have assessed whether treatment of acute cervical spinal cord injury (SCI) patients contributes to depression. Methods Using an administrative database, we assessed patients for whom the diagnosis was unspecified injuries of cervical spinal cord (International Classification of Diseases and Injuries-10th (ICD-10) code; S14.1). We categorized patients with codes for depressive episode (ICD-10 code; F32) or recurrent depressive disorder (F33), or those prescribed antidepressants (tricyclic, tetracyclic, Selective Serotonin Reuptake Inhibitors, Serotonin Noradrenaline Reuptake Inhibitors, Trazodone, Sulpiride, or Mirtazapine) as having a depressive state. We compared the rate of each acute treatment between the depressive state group and the non-depressive state group using chi-square tests, and a multiple logistic regression model was used to identify the association between the acute treatment and depressive state. Results There were 151 patients who were judged to be in a depressive state, and the other 2115 patients were categorized into the non-depressive state group. Intervention of intravenous anesthesia, tracheostomy, artificial respiration, and gastrostomy had a significant positive correlation with depressive state. Multiple logistic regression analysis showed that tracheostomy (odds ratio [OR] 2.18; 95% confidence interval [CI], 1.09–4.38) and artificial respiration (OR 2.28; 95% CI, 1.32–3.93) were significantly associated with depressive state, and men had a 36% reduction in the risk of depressive state compared with women (OR 0.64; 95% CI, 0.44–0.94), whereas age, wound-treatment, all of the orthopedic procedures, intravenous anesthesia, and gastrostomy were not associated with depressive state. Conclusions These findings suggest that tracheostomy, artificial respiration and female gender in the acute phase after cervical SCI might be associated with the development of depression.

    Chronic bronchitis is a relatively common entity among patients with underlying chronic obstructive lung disease. Typical treatment includes pulmonary hygiene, bronchodilators, and antimicrobial therapy. In recent years, the duration of antimicrobial therapy in acute exacerbations of COPD has become shorter and shorter. This review summarizes the data on the use of the drug azithromycin for this particular patient population with a focus on 3-day and single-day therapy. PMID:19281070

    Although operative techniques in hepatic transplantation have reduced the time and mortality on waiting lists, the rate of vascular complications associated with these techniques has increased. Stenosis or thrombosis of the portal vein is an infrequent complication, and if present, surgical treatment is considered the traditional management. This article describes a case of acute portal vein thrombosis after liver transplantation from a living donor to a child managed by percutaneous techniques.

    The cerebellar glomerulus was studied by electron microscopic morphometry in female Wistar rats. Age-dependent alterations have been revealed from 3 to 28 mth of age, and the effect of centrophenoxine (CPH) was analyzed in two different patterns of administration. First, 27-mth-old rats were treated daily for 6 wk (acute treatment), and second, 18-mth-old rats were treated 3 times per week for 5 months (chronic treatment). The dose was 100 mg CPH/kg body weight, injected intraperitoneally. The surface density (SV), the numerical density (NV) and the average length (L) of the synaptic junctions were calculated from data obtained on ethanol-phosphotungstic acid stained ultrathin sections. An age-dependent reduction of SV and NV of the synaptic contact zones was found, and the L increased in the oldest animals. CPH-treatment resulted in a marked increase of SV in both types of application, whereas the other two parameters behaved differently in the two groups. The chronic treatment resulted in a significant slowing down of the decrease of NV, whereas L remained invariate. On the contrary, the acute treatment increased L but did not alter significantly NV. The results and the differences between the treatment types are discussed in terms of synaptic plasticity and are interpreted as different manifestations of the same reactive synaptogenetic process.

    Abdominal compartment syndrome (ACS) in patients with severe acute pancreatitis (SAP) is a marker of severe disease. It occurs as combination of inflammation of retroperitoneum, visceral edema, ascites, acute peripancreatic fluid collections, paralytic ileus, and aggressive fluid resuscitation. The frequency of ACS in SAP may be rising due to more aggressive fluid resuscitation, a trend towards conservative treatment, and attempts to use a minimally invasive approach. There remains uncertainty about the most appropriate surgical technique for the treatment of ACS in SAP. Some unresolved questions remain including medical treatment, indications, timing, and interventional techniques. This review will focus on interventional treatment of this serious condition. First line therapy is conservative treatment aiming to decrease IAP and to restore organ dysfunction. If nonoperative measures are not effective, early abdominal decompression is mandatory. Midline laparostomy seems to be method of choice. Since it carries significant morbidity we need randomized studies to establish firm advantages over other described techniques. After ACS resolves efforts should be made to achieve early primary fascia closure. Additional data are necessary to resolve uncertainties regarding ideal timing and indication for operative treatment. PMID:26839539

    AIM: To study the effect of combined indwelling catheter, hemofiltration, respiration support and traditional Chinese medicine (e.g. Dahuang) in treating abdominal compartment syndrome of fulminant acute pancreatitis. METHODS: Patients with fulminant acute pancreatitis were divided randomly into 2 groups of combined indwelling catheter celiac drainage and intra-abdominal pressure monitoring and routine conservative measures group (group 1) and control group (group 2). Routine non-operative conservative treatments including hemofiltration, respiration support, gastrointestinal TCM ablution were also applied in control group patients. Effectiveness of the two groups was observed, and APACHE II scores were applied for analysis. RESULTS: On the second and fifth days after treatment, APACHE II scores of group 1 and 2 patients were significantly different. Comparison of effectiveness (abdominalgia and burbulence relief time, hospitalization time) between groups 1 and 2 showed significant difference, as well as incidence rates of cysts formation. Mortality rates of groups 1 and 2 were 10.0% and 20.7%, respectively. For patients in group 1, celiac drainage quantity and intra-abdominal pressure, and hospitalization time were positively correlated (r = 0.552, 0.748, 0.923, P < 0.01) with APACHE II scores. CONCLUSION: Combined indwelling catheter celiac drainage and intra-abdominal pressure monitoring, short veno-venous hemofiltration (SVVH), gastrointestinal TCM ablution, respiration support have preventive and treatment effects on abdominal compartment syndrome of fulminant acute pancreatitis.

    There are at least three distinct fracture patterns that occur in the proximal fifth metatarsal: tuberosity avulsion fractures, acute Jones fractures, and diaphyseal stress fractures. Each of these fracture patterns has its own mechanism of injury, location, treatment options, and prognosis regarding delayed union and nonunion. Tuberosity avulsion fractures are the most common in this region of the foot. The majority heal with symptomatic care in a hard-soled shoe. The true Jones fracture is an acute injury involving the fourth-fifth intermetatarsal facet. These injuries are best treated with non-weight-bearing cast immobilization for 6 to 8 weeks. The rate of successful union with this treatment has been reported to be between 72% and 93%. For the high-performance athlete with an acute Jones fracture, early intramedullary-screw fixation is an accepted treatment option. Nonacute diaphyseal stress fractures of the proximal fifth metatarsal and Jones fractures that develop into delayed unions and nonunions can both be managed with operative fixation with either closed axial intramedullary-screw fixation or autogenous corticocancellous grafting. Early results with the use of electrical stimulation are promising; however, prospective studies are needed to better define the role of this modality in managing these injuries.

    Oritavancin, a semisynthetic derivative of the glycopeptide antibiotic chloroeremomycin, received the US Food and Drug Administration approval for the treatment of acute bacterial skin and skin structure infections caused by susceptible Gram-positive bacteria in adults in August 2014. This novel second-generation semisynthetic lipoglycopeptide antibiotic has activity against a broad spectrum of Gram-positive bacteria, including methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-intermediate S. aureus (VISA), and vancomycin-resistant Enterococcus. Oritavancin inhibits bacterial cell wall synthesis and is rapidly bactericidal against many Gram-positive pathogens. The long half-life of this drug enables a single-dose administration. Oritavancin is not metabolized in the body, and the unchanged drug is slowly excreted by the kidneys. In two large Phase III randomized, double-blind, clinical trials, oritavancin was found to be non-inferior to vancomycin in achieving the primary composite end point in the treatment of acute Gram-positive skin and skin structure infections. Adverse effects noted were mostly mild with nausea, headache, and vomiting being the most common reported side effects. Oritavancin has emerged as another useful antimicrobial agent for treatment of acute Gram-positive skin and skin structure infections, including those caused by MRSA and VISA. PMID:26185459

    Despite the advances in understanding the pathophysiology of acute myeloid leukaemia (AML), the cure rate for acute myeloid leukaemia patients remains low. Cytogenetic abnormalities and age are the prognostic factors that guide treatment decisions. However, many AML patients still die. The biological factors that influence treatment outcome are largely unknown. Thus, the objective of our study was to use the in vitro viability test to correlate with treatment outcome. Acute myeloid leukaemia blasts demonstrated differing ability to survive in culture. Our examination of blast phenotype at various days in culture showed two possible growth directions. First, cells underwent maturation by increased expression of CD16 and down-regulated CD34 (a haemopoietic stem cell marker). These cells also appeared to have undergone apoptosis. Alternatively, cells continued to survive in culture and maintained high expression of CD34. An MTT assay was carried out to determine viability after three days of culture. Lower optical density values were obtained for samples that underwent apoptosis and higher values were obtained for samples that survived in culture. Apoptosis was measured by Annexin V/propidium iodide staining. A comparison between results of MTT assay and duration of disease free survival revealed that a higher viability in vitro correlated significantly with shorter survival duration in the patient (R -0.761, p=0.002, n=13). Thus, this study further supports the hypothesis that AML patients with poor survival may be related to having blasts with a biologically more immature or stem cell-like nature.

    This study was undertaken to (a) determine wastewater treatment effectiveness using two freshwater organisms, (b) compare acute toxicity results from the two species exposed to the wastewaters, and (c) link acute and potential developmental toxicity of wastewaters in one organism. The acute toxicities of several pretreatment and post-treatment industrial waste-water samples wee evaluated with adult Hydra attenuata and fathead minnows. The acute LC50s agreed closely when results in Hydra attenuata were compared with those from fathead minnow tests. Acute LC50s ranged from 3 to >100% of samples with hydra, and from 1.0 to >100% of sample with fathead minnows. The results provided strong evidence of treatment effectiveness because toxicity decreased with progressive stages of treatment. Previously the Hydra Developmental Toxicity Assay was used as a prescreen mainly for in vitro assessment of developmental toxicity with pure compounds and to prioritized toxicants according to selective toxicity to the developing embryo. Recently the authors modified the assay for testing natural waters and wastewaters; hence, some of the wastewater samples also were tested for their developmental toxicity. In this case, the relative selective toxicity of these wastewater samples ranged from 0.7 to 2.1, indicating that no sample was uniquely toxic to the developing embryo, although acute toxicity was manifested. Overall, their results indicate the Hydra Assay functions appropriately in assessments of acute and developmental toxicity of industrial wastewaters and may be a simple and useful tool in a battery of tests for broader scale detection of environmental hazards.

    Acute ankle injuries are among the most common injuries in emergency departments. However, there are still no standardized examination procedures or evidence-based treatment. Therefore, the aim of this study was to systematically search the current literature, classify the evidence, and develop an algorithm for the diagnosis and treatment of acute ankle injuries. We systematically searched PubMed and the Cochrane Database for randomized controlled trials, meta-analyses, systematic reviews or, if applicable, observational studies and classified them according to their level of evidence. According to the currently available literature, the following recommendations have been formulated: i) the Ottawa Ankle/Foot Rule should be applied in order to rule out fractures; ii) physical examination is sufficient for diagnosing injuries to the lateral ligament complex; iii) classification into stable and unstable injuries is applicable and of clinical importance; iv) the squeeze-, crossed leg- and external rotation test are indicative for injuries of the syndesmosis; v) magnetic resonance imaging is recommended to verify injuries of the syndesmosis; vi) stable ankle sprains have a good prognosis while for unstable ankle sprains, conservative treatment is at least as effective as operative treatment without the related possible complications; vii) early functional treatment leads to the fastest recovery and the least rate of reinjury; viii) supervised rehabilitation reduces residual symptoms and re-injuries. Taken these recommendations into account, we present an applicable and evidence-based, step by step, decision pathway for the diagnosis and treatment of acute ankle injuries, which can be implemented in any emergency department or doctor's practice. It provides quality assurance for the patient and promotes confidence in the attending physician. PMID:22577506

    Acute kidney injury (AKI) is increasingly recognized in all fields of medical practice. Unfortunately, this syndrome has been plagued by inconsistent definitions, simplistic pathophysiologic schemas, and insensitive diagnostic tools. Recent advances in defining AKI, understanding its pathophysiology, and improving the diagnostic accuracy of the testing tools available eventually will impact disease management and clinical outcomes. Prompt recognition and treatment of AKI remain the cornerstone of clinical management for this high-mortality, high-cost syndrome. The authors provide the most recent updates in the definition, diagnosis, pathophysiology, and treatment options for patients with AKI, providing a stepwise approach to clinical evaluation for use in all fields of medical practice.

    The present report describes the cases of a 17-year-old male patient and a 13-year-old female patient who developed acute dystonia following the administration of low-dose aripiprazole (5 mg/day) after the cessation of atomoxetine treatment. Although aripiprazole-induced dystonia has been previously reported in the literature, it is rare, and most of these cases were associated with doses higher than 5 mg/day. Furthermore, both of the patients in the present study discontinued atomoxetine prior to the initiation of aripiprazole treatment; thus, this report also discussed the possible mechanisms underlying the manifestation of dystonia from the perspective of neurotransmitter activity.

    With the growing interest in adventure travel and the increasing ease and affordability of air, rail, and road-based transportation, increasing numbers of individuals are traveling to high altitude. The decline in barometric pressure and ambient oxygen tensions in this environment trigger a series of physiologic responses across organ systems and over a varying time frame that help the individual acclimatize to the low oxygen conditions but occasionally lead to maladaptive responses and one or several forms of acute altitude illness. The goal of this Physiology in Medicine article is to provide information that providers can use when counseling patients who present to primary care or travel medicine clinics seeking advice about how to prevent these problems. After discussing the primary physiologic responses to acute hypoxia from the organ to the molecular level in normal individuals, the review describes the main forms of acute altitude illness--acute mountain sickness, high-altitude cerebral edema, and high-altitude pulmonary edema--and the basic approaches to their prevention and treatment of these problems, with an emphasis throughout on the physiologic basis for the development of these illnesses and their management.

    The progressive aging of the population is associated with an increase in the proportion of very old patients (greater than 75 years) hospitalized with acute myocardial infarction. The lack of evidence regarding the efficacy of most therapeutic interventions for acute myocardial infarction in these patients is leading to a significant degree of uncertainty in the cardiology community with respect to their optimal management. When aggressive treatment (defined as a therapeutic strategy designed to obtain and maintain a patent infarct-related coronary artery at an early moment) of acute myocardial infarction is considered in very old patients, three main questions should be addressed: why should we treat? Whom should we treat? And how should we treat? To answer these questions, the authors reviewed the data available in the literature as well as new data from the PPRIMM75 (Pronóstico del PRimer Infarto de Miocardio en Mayores de 75 aÃ+/-os) Registry, a large, prospective database of patients aged 75 years or older, admitted to a single coronary care unit in Madrid, Spain, for their first acute myocardial infarction during the last decade.

    Intracerebral hemorrhage (ICH) is a common stroke subtype in Japan. Hypertension is the leading cause. Perindopril Protection Against Recurrent Stroke Study (PROGRESS) revealed that blood pressure (BP) lowering could reduce stroke recurrence by 28% (ICH recurrence by 49%). The guideline for the management of hypertension (JSH2009) recommends BP control of ≤ 140/90 mm Hg for patients with prior stroke. BP is frequently elevated in acute ICH, although BP management strategy is controversial. The guideline from the American Stroke Association suggests if systolic BP (SBP) >180 mm Hg and there is no evidence of elevated intracranial pressure, then consider a modest reduction of BP. A nationwide survey revealed that SBP lowering to ≤ 160 mm Hg using intravenous nicardipine in acute ICH is a major strategy in Japan, and the safety was confirmed by a multicenter, prospective, observational study. Intensive Blood Pressure Reduction in Acute Cerebral Haemorrhage Trial (INTERACT) and Antihypertensive Treatment of Acute Cerebral Hemorrhage (ATACH) showed the feasibility and safety of early rapid BP lowering to 140 mm Hg. INTERACT2 and ATACH II are the randomized trials to compare the guideline-based control (<180 mm Hg) and strict control (<140 mm Hg). We have just started to enroll patients to ATACH II from Japan on February 2012.

    A 22-year-old black man developed fever, chills, fatigue, night sweats, tender lymphadenopathy, and a generalized, pruritic, macular eruption 3 weeks after starting minocycline therapy for acne. His illness was also characterized by a palpable spleen tip, marked lower extremity and scrotal edema, and generalized lymphadenopathy. The patient had leukocytosis with a large percentage of atypical lymphocytes on peripheral smear and liver dysfunction. Titers for Epstein-Barr virus, hepatitis B, toxoplasmosis; and cytomegalovirus were all negative. Human immunodeficiency virus-1 viral load and antibodies were also negative. Marked improvement was noted after the discontinuation of minocycline and the use of systemic corticosteroids. With the negative viral serologies, the clinical picture was most consistent with an infectious mononucleosis-like syndrome produced by the minocycline ingestion.

    Asparaginases are a cornerstone of treatment protocols for acute lymphoblastic leukemia (ALL) and are used for remission induction and intensification treatment in all pediatric regimens and in the majority of adult treatment protocols. Extensive clinical data have shown that intensive asparaginase treatment improves clinical outcomes in childhood ALL. Three asparaginase preparations are available: the native asparaginase derived from Escherichia coli (E. coli asparaginase), a pegylated form of this enzyme (PEG-asparaginase), and a product isolated from Erwinia chrysanthemi, ie, Erwinia asparaginase. Clinical hypersensitivity reactions and silent inactivation due to antibodies against E. coli asparaginase, lead to inactivation of E. coli asparaginase in up to 60% of cases. Current treatment protocols include E. coli asparaginase or PEG-asparaginase for first-line treatment of ALL. Typically, patients exhibiting sensitivity to one formulation of asparaginase are switched to another to ensure they receive the most efficacious treatment regimen possible. Erwinia asparaginase is used as a second- or third-line treatment in European and US protocols. Despite the universal inclusion of asparaginase in such treatment protocols, debate on the optimal formulation and dosage of these agents continues. This article provides an overview of available evidence for optimal use of Erwinia asparaginase in the treatment of ALL.

Two policies funding for the catastrophic diseases and the new rural cooperative medical care system (NRCMS) were initiated in 2005 and 2011, respectively. About 1151 children diagnosed with acute lymphoblastic leukemia were enrolled in our study during this period and 316 cases abandoned treatment. Statistical differences in sex, age, number of children in the family, and family financial status were observed. Of most importance, the medical insurance coverage was critical for reducing abandonment treatment. However, 92 cases abandoning treatment after relapse did not show significant difference either in medical insurance coverage or in duration from first complete remission. In conclusion, financial crisis was the main reason for abandoning treatment. Government-funded health care expenditure programs reduced families' economic burden and thereby reduced the abandonment rate with resultant increased overall survival.

In 19 (16%) of 119 MEF culture-positive patients, an organism susceptible to the treatment drug (Haemophilus influenzae, Streptococcus pneumoniae, or both) was isolated from the initial MEF, whereas resistant S. pneumoniae was present in the NP; in 9 (47%) patients, the initial resistant NP organism (identified by serotyping, resistance to the administered drug, and pulsed-field gel electrophoresis) replaced the susceptible MEF organism within only a few days after initiation of treatment. In regions where resistant pneumococci are prevalent, antibiotics may not only fail to eradicate the organisms, but they may often induce MEF superinfection with resistant pneumococci initially carried in the NP. This is an important mechanism by which, in recently treated patients, AOM infections often become refractory to treatment. PMID:11237804

  12. Clinical review: Early treatment of acute lung injury - paradigm shift toward prevention and treatment prior to respiratory failure

    PubMed Central

    2012-01-01

    Acute lung injury (ALI) remains a major cause of morbidity and mortality in critically ill patients. Despite improved understanding of the pathogenesis of ALI, supportive care with a lung protective strategy of mechanical ventilation remains the only treatment with a proven survival advantage. Most clinical trials in ALI have targeted mechanically ventilated patients. Past trials of pharmacologic agents may have failed to demonstrate efficacy in part due to the resultant delay in initiation of therapy until several days after the onset of lung injury. Improved early identification of at-risk patients provides new opportunities for risk factor modification to prevent the development of ALI and novel patient groups to target for early treatment of ALI before progression to the need for mechanical ventilation. This review will discuss current strategies that target prevention of ALI and some of the most promising pharmacologic agents for early treatment of ALI prior to the onset of respiratory failure that requires mechanical ventilation.

  13. The variation of acute treatment costs of trauma in high-income countries

    PubMed Central

    2012-01-01

    Background In order to assist health service planning, understanding factors that influence higher trauma treatment costs is essential. The majority of trauma costing research reports the cost of trauma from the perspective of the receiving hospital. There has been no comprehensive synthesis and little assessment of the drivers of cost variation, such as country, trauma, subgroups and methods. The aim of this review is to provide a synthesis of research reporting the trauma treatment costs and factors associated with higher treatment costs in high income countries. Methods A systematic search for articles relating to the cost of acute trauma care was performed and included studies reporting injury severity scores (ISS), per patient cost/charge estimates; and costing methods. Cost and charge values were indexed to 2011 cost equivalents and converted to US dollars using purchasing power parities. Results A total of twenty-seven studies were reviewed. Eighty-one percent of these studies were conducted in high income countries including USA, Australia, Europe and UK. Studies either reported a cost (74.1%) or charge estimate (25.9%) for the acute treatment of trauma. Across studies, the median per patient cost of acute trauma treatment was $22,448 (IQR: $11,819-$33,701). However, there was variability in costing methods used with 18% of studies providing comprehensive cost methods. Sixty-three percent of studies reported cost or charge items incorporated in their cost analysis and 52% reported items excluded in their analysis. In all publications reviewed, predictors of cost included Injury Severity Score (ISS), surgical intervention, hospital and intensive care, length of stay, polytrauma and age. Conclusion The acute treatment cost of trauma is higher than other disease groups. Research has been largely conducted in high income countries and variability exists in reporting costing methods as well as the actual costs. Patient populations studied and the cost methods

    Objective: To report our 10-year diagnosis and treatment experience of acute urogenital and genitalia tract traumas and outline the management of the traumatic injury. Methods: We reviewed the diagnoses and treatments of 208 cases of acute kidney, ureter, bladder, urethra, or male genitalia injuries in our department between March 2002 and March 2012. The patient data including general information, injury position and mechanism, diagnosis and treatment, the follow-up information was analyzed and summarized. Results: Of 62 patients with renal injury examined by ultrasound and computed tomography (CT) examination, 45 were treated conservatively, 9 with superselective arterial embolization, and 8 with nephrectomy. Intravenous pyelogram (IVP) was conducted in two patients with ureteral injury, one was treated with cystoscopic ureteral catheterization and the other with ureteric reimplantation. Bladder injury (6 patients) confirmed with a waterflood susceptibility test combined with CT scans underwent laparotomy and the bladder suturing was done. Of 92 patients with urethral injury, 6 were treated with a nonoperative approach (indwelling catheter), 18 with urethral realignment, 35 with cystoscopic urethral realignment, 29 with end-to-end anastomotic urethroplasty, and 4 with urethral repairmen. Of the 24 cases with penile injuries, 1 underwent conservative treatment, 8 were treated with debridement and suture ligation, and 15 were managed with suture repair of the penis white membrane. Of the 24 cases with penile injuries, 1 underwent conservative treatment, 8 were treated with debridement and suture ligation, and 15 were managed with suture repair of the penis white membrane. During the follow-up period, 62 patients with renal injury had normal renal function. Neither of the two patients with ureteral injury developed hydronephrosis. Twenty-nine patients with urethral injury suffered from urethral structure. All patients with vesical or genital injury recovered

    Selecting suitable anti-malarial treatment represents one of the best tools for reducing morbidity and mortality caused by this disease. Sexual and asexual parasite dynamics were thus evaluated in patients involved in antimalarial drug efficacy studies by using combined treatment with and without artemisinin derivatives for treating uncomplicated acute Plasmodium falciparum malaria in Antioquia, Colombia. All treatment doses were supervised and administered according to patients' weight; sexual and asexual parasitemia were evaluated during 28- or 42-days follow-up in 468 patients. Artemisinin-based combination therapy showed greater parasiticidal ability, showing a mean asexual parasitemia survival rate of one day and mean gametocyte survival rate of 1–2 days. Sexual and asexual parasitemias were eliminated more quickly and effectively in the group receiving artemisinin-based combination therapy. Adding 45 mg of primaquine to treatment with artesunate and mefloquine reduced gametocyte and asexual parasite survival by one day. PMID:20595483

    Objective Older adults with anxiety disorders are burdened by impairment in neurocognition, which may be mediated by elevated circulating cortisol levels. In a randomized controlled trial of acute serotonin-reuptake inhibitor treatment for late-life anxiety disorder, we examined whether change in salivary cortisol concentrations during treatment predicted improvements in measures of memory and executive function. Methods We examined 60 adults aged 60 and older, who took part in a 12-week trial of escitalopram vs. placebo for Generalized Anxiety Disorder. All subjects had pre- and post-treatment assessments that included monitoring of peak and total daily cortisol and a comprehensive neuropsychological evaluation. Results Salivary cortisol changes during treatment showed significant associations with changes in immediate and delayed memory, but no association with executive tasks (measures of working memory and set-shifting). Analyses suggested that a decrease in cortisol due to serotonin-reuptake inhibitor treatment was responsible for the memory changes: memory improvement was seen with cortisol reduction among patients receiving escitalopram, but not among patients receiving placebo. Conclusion Serotonin-reuptake inhibitor-induced alteration in circulating cortisol during treatment of Generalized Anxiety Disorder predicted changes in immediate and delayed memory. This finding suggests a novel treatment strategy in late-life anxiety disorders: targeting HPA axis dysfunction to improve memory. PMID:21681817

    We developed a stroma cell culture system that suppresses apoptosis of malignant cells from cases of B-lineage acute lymphoblastic leukemia. By multiparameter flow cytometric measurements of cell recovery after culture on stromal layers, we assessed the growth potential of 70 cases of newly diagnosed B-lineage acute lymphoblastic leukemia and related the findings of treatment outcome in a single program of chemotherapy. The numbers of leukemic cells recovered after 7 d of culture ranged from < 1 to 292% (median, 91%). The basis of poor cell recoveries from stromal layers appeared to be a propensity of the lymphoblasts to undergo apoptosis. The probability of event-free survival at 4 yr of follow-up was 50 +/- 9% (SE) among patients with higher cell recoveries ( > 91%), and 94 +/- 6% among those with reduced cell recoveries (+/- 91%; P = 0.0003). The prognostic value of leukemic cell recovery after culture exceeded estimates for all other recognized high-risk features and remained the most significant after adjustment with all competing covariates. Thus, the survival ability of leukemic cells on bone marrow-derived stromal layers reflects aggressiveness of the disease and is a powerful, independent predictor of treatment outcome in children with B-lineage acute lymphoblastic leukemia.

    Levofloxacin is a widely used fluoroquinolone approved for the treatment of complicated urinary tract infections and acute pyelonephritis. A comprehensive review of the medical literature identified five publications evaluating levofloxacin for the treatment of either complicated urinary tract infections or acute pyelonephritis. All trials, although variable in their inclusion criteria and levofloxacin dosing strategies, reported microbiologic, clinical, and safety-related outcomes. High microbiologic eradication rates, ranging from 79.8% to 95.3%, were observed in all studies. Escherichia coli was the most commonly isolated uropathogen. Data on levofloxacin resistance, both at baseline and after therapy, were limited. Clinical success was observed to range from 82.6% to 93% when measured after the completion of therapy. These clinical and microbiologic results were comparable to the fluoroquinolone comparators in all trials. Insufficient data are available to evaluate the outcomes in any meaningful patient subgroups, including catheterized patients, and those with other specific complicating factors. Levofloxacin was well tolerated in these studies, with headache, gastrointenstinal effects, and dizziness being the most commonly reported adverse events. The published data support the use of levofloxacin in complicated urinary tract infections and acute pyelonephritis. Further trials are necessary to evaluate levofloxacin within specific patient sub-populations. PMID:19209267

    Innate immunity mediated by microglia appears to play a crucial role in initiating and propagating seizure-induced inflammatory responses. To address the role of activated microglia in the pathogenesis of childhood epilepsy, we first examined the time course of microglia activation following kainic acid-induced status epilepticus (KA-SE) in Cx3cr1(GFP/+) transgenic mice whose microglia are fluorescently labeled. We then determined whether this seizure-induced microglia activation primes the central immune response to overreact and to increase the susceptibility to a second seizure later in life. We used an inhibitor of microglia activation, minocycline, to block the seizure-induced inflammation to determine whether innate immunity plays a causal role in mediating the long-term epileptogenic effects of early-life seizure. First status epilepticus was induced at postnatal day (P) 25 and a second status at P39. KA-SE at P25 caused nearly a two-fold increase in microglia activation within 24h. Significant seizure-induced activation persisted for 7 days and returned to baseline by 14 days. P39 animals with prior exposure to KA-SE not only responded with greater microglial activation in response to "second hit" of KA, but shorter latency to express seizures. Inhibition of seizure-induced inflammation by 7 day minocycline post-treatment abrogated both the exaggerated microglia activation and the increased susceptibility to the second seizure later in life. The priming effect of early-life seizures is accompanied by modified and rapidly reactivated microglia. Our results suggest that anti-inflammatory therapy after SE may be useful to block the epileptogenic process and mitigate the long-term damaging effects of early-life seizures. PMID:22366182

    Asparaginases are a cornerstone of treatment protocols for acute lymphoblastic leukemia (ALL) and are used for remission induction and intensification treatment in all pediatric regimens and in the majority of adult protocols. Extensive clinical data have shown that intensive asparaginase treatment improves clinical outcomes in childhood ALL. Three asparaginase preparations are available; the native asparaginase derived from Escherichia coli (E. coli-asparaginase), a pegylated form of this enzyme (PEG-asparaginase) and a product isolated from Erwinia chrysanthemi, i.e. Erwinia asparaginase. Clinical hypersensitivity reactions and silent inactivation due to antibodies against E.coli-asparaginase, lead to inactivation of E-Coli asparaginase in up to 60% of cases. Current treatment protocols include E. coli-asparaginase or PEG-asparaginase for first-line treatment of ALL. Typically, patients exhibiting sensitivity to one formulation of asparaginase are switched to another product to ensure they receive the most efficacious treatment regimen possible. Erwinia asparaginase is used as a second- or third-line treatment in European and US protocols. Despite the universal inclusion of asparaginase in such treatment protocols, there is much debate regarding the optimal formulation and dosage of these agents. This manuscript provides an overview of available evidence to make recommendations for optimal use of Erwinia asparaginase in the treatment of ALL. PMID:20824725

    Objective: To investigate the effect of continuous venovenous hemofiltration (CVVH) for aortic dissection patients with acute renal failure after surgery in retrospective manner. Methods: A total of thirty-seven aortic dissection patients with postoperative acute renal failure accepted CVVH therapy. The effect of CVVH was evaluated by analyzing clinical condition changes and laboratory examination results. Results: After treatment of CVVH, renal function and clinical symptoms were significantly improved in thirty patients. Eight of the thirty patients got completely renal function recovery within two weeks after CVVH therapy; and twenty-two of the thirty patients got completely renal function recovery within four weeks after CVVH therapy. Nevertheless, seven patients got no benefit from CVVH therapy with poor prognosis. Conclusion: CVVH is an effective treatment to most aortic dissection patients with postoperative acute renal failure. The effect of CVVH was correlated with original renal function, early CVVH therapy, and continuous intensive care. PMID:26550312

    Objective Single voxel proton magnetic resonance spectroscopy (MRS) can be used to monitor changes in brain inflammation and neuronal integrity associated with HIV infection and its treatments. We used MRS to measure brain changes during the first weeks following HIV infection and in response to antiretroviral therapy (ART). Methods Brain metabolite levels of N-acetyl aspartate (NAA), choline (tCHO), creatine (CR), myoinositol (MI), and glutamate and glutamine (GLX) were measured in acute HIV subjects (n = 31) and compared to chronic HIV+individuals (n = 26) and HIV negative control subjects (n = 10) from Bangkok, Thailand. Metabolites were measured in frontal gray matter (FGM), frontal white matter (FWM), occipital gray matter (OGM), and basal ganglia (BG). Repeat measures were obtained in 17 acute subjects 1, 3 and 6 months following initiation of ART. Results After adjustment for age we identified elevated BG tCHO/CR in acute HIV cases at baseline (median 14 days after HIV infection) compared to control (p = 0.0014), as well as chronic subjects (p = 0.0023). A similar tCHO/CR elevation was noted in OGM; no other metabolite abnormalities were seen between acute and control subjects. Mixed longitudinal models revealed resolution of BG tCHO/CR elevation after ART (p = 0.022) with tCHO/CR similar to control subjects at 6 months. Interpretation We detected cellular inflammation in the absence of measurable neuronal injury within the first month of HIV infection, and normalization of this inflammation following acutely administered ART. Our findings suggest that early ART may be neuroprotective in HIV infection by mitigating processes leading to CNS injury. PMID:23229129

    This study presents the design of a gold nanoparticle (AuNPs)-drug system with improved efficiency for the treatment of acute myeloid leukemia. The system is based on four different FLT3 inhibitors, namely midostaurin, sorafenib, lestaurtinib, and quizartinib, which were independently loaded onto gelatin-coated gold nanoparticles. Detailed investigation of the physicochemical properties of the formed complexes lead to the selection of quizartinib-loaded AuNPs for the in vitro evaluation of the biological effects of the formed complex against OCI-AML3 acute myeloid leukemia cells. Viability tests by MTT demonstrated that the proposed drug complex has improved efficacy when compared with the drug alone. The obtained results constitute a premise for further in vivo investigation of such drug vehicles based on AuNPs. To the best of our knowledge, this is the first study that investigates the delivery of the above-mentioned FLT3 inhibitors via gelatin-coated gold nanoparticles. PMID:26808072

    Orlistat is a pancreatic lipase inhibitor which is used to treat obesity. Due to the increasing prevalence of obesity, orlistat use is thought to rise progressively. We report an interesting case caused by orlistat use caught in the early stages of acute pancreatitis through imaging; in addition, the case had significantly elevated serum amylase levels. A 54-year-old male who had a history of orlistat treatment started 7 days before was admitted to the emergency department with complaints of abdominal pain, nausea and vomiting lasting for 24 h. Abdominal computed tomography revealed peripancreatic fat tissue edema and a heterogeneous appearance of the pancreas. Based on these findings, it was concluded that edematous pancreatitis was in its initial stage. Orlistat is a drug that is increasingly widespread use due to obesity. More attention must be paid when planning to prescribe orlistat to patients if there are risk factors for acute pancreatitis (alcohol use, height, serum calcium and lipid levels). PMID:26078734

    Numerous procedures have been described for the operative management of acromioclavicular (AC) joint injuries. Some of these techniques, including hardware fixation and non-anatomical reconstructions, are associated with serious complications and high failure rates. Recently, AC joint reconstruction techniques have focused on anatomical restoration of the coracoclavicular ligaments to achieve optimal clinical outcomes. We used a triple endobutton technique to separately reconstruct the trapezoid and the coronoid portions of the coracoclavicular ligament. We evaluated the preliminary clinical and radiological results of this technique in patients with acute complete dislocation of the AC joint. All patients achieved a significant improvement in the pain and function of shoulder at a mean follow-up interval of 12 months (range, 8-14 months). Excellent reduction of the AC joint was maintained. The triple endobutton technique may be safe and effective for the treatment of acute complete AC joint dislocations.

    Introduction Controversy remains regarding the optimal treatment method and postoperative rehabilitation of acute Achilles tendon ruptures. In this study, pedobarographic assessments of surgical and conservative treatments were compared. Material and methods A prospective assessment was made of 16 patients (eight surgical, eight conservative) and eight healthy controls using a plantar pressure measurement system. Biomechanical gait parameters were obtained using the Footscan dynamic gait analysis system. Kruskal–Wallis and Mann–Whitney U-tests were used for the evaluation of data. Results Nineteen males and five females were assessed, with an average age of 42.0±11.9 years. Follow-up was completed in 16 patients. No statistically significant difference was determined between the two treatment groups with regard to the gait analysis, but a difference was observed with the control group (P<0.001). All patients were able to resume their prior activities after 6 months and regained normal ranges of motion, with a high rate of satisfaction. Most of the patients (75%) were able to return to their pre-injury level of activities. Conclusion Satisfactory results were obtained through conservative treatment of acute ruptures of the Achilles tendon. No significant differences or complications were observed in the group managed conservatively versus the group treated surgically. Further studies including 3D gait analyses and tendon biomechanical research are required to further investigate this issue. PMID:27621640

    Forty-five adolescent and preadolescent patients (42 females, three males) with anorexia nervosa (AN) were treated in a pediatric day care unit of a large urban hospital by a multidisciplinary team. In our treatment model, the pediatrician has the responsibility for the initial evaluation and physical rehabilitation while the pediatric psychiatrist does the initial evaluation of the patient and family and is available for intervention in an emergency. Parents are actively involved in the treatment program. Family psychotherapy is recommended for each patient and his or her family. Among 45 patients, 24 did not enter psychotherapy during the first 2 months of the refeeding period, while the remaining 21 patients started psychotherapy (family and/or individual) during this period. Weight gain was higher in the group without formal psychotherapy during the initial period of refeeding (7.3 +/- 3.1 kg versus 5 +/- 2.5 kg; p less than 0.01). It is suggested that the initiation of structured psychotherapy is not mandatory and does not contribute to treatment effectiveness in the acute phase when emaciation and negativism may hinder the psychotherapeutic process. We believe a multidisciplinary team, together with the parents, is the treatment of choice during the acute phase of AN.

    Severe acute pancreatitis (SAP) is recognized as critical refractory disease. The case fatality rate of SAP is as high as 36%-50%. Although significant progress has been achieved on the treatment of severe acute pancreatitis (SAP) by Integrated Traditional Chinese Medicine (TCM) and Western Medicine (WM), there still exist some difficulties hindering the further improvement of therapeutic efficacy. The hot issues includes: unconfirmative curative effects and diverse treatment principles, complicated predictive scoring systems and inaccurate markers for the severity stratification, unproved new therapeutic tools and controversial methods waiting more high qualified evidence, unclarified mechanism of Integrated TCM and WM. In order to overcome the difficulties, we aim to launch the clinical pathway of Integrated TCM and WM, to strengthen the unity of multidisciplinary cooperation. We also need to keep the efforts on screening the markers for early evaluation and prediction of disease severity, improving the diagnosis and treatment, exploring the mechanism of Traditional Chinese Medicine in treating SAP with more high quality basic and clinical research. Based on these efforts, we could provide better treatments and prognosis for SAP patients.

    Rapid eye movement (REM) sleep deprivation (SD) is implicated in impairment of spatial learning and memory and hippocampal long-term potentiation (LTP). An increase in nicotine consumption among habitual smokers and initiation of tobacco use by nonsmokers was observed during SD. Although nicotine treatment was reported to attenuate the impairment of learning and memory and LTP associated with several mental disorders, the effect of nicotine on SD-induced learning and memory impairment has not been studied. Modified multiple platform paradigm was used to induce SD for 24 or 48 h during which rats were injected with saline or nicotine (1 mg kg(-1) s.c.) twice a day. In the radial arm water maze (RAWM) task, 24- or 48-h SD significantly impaired learning and short-term memory. In addition, extracellular recordings from CA1 and dentate gyrus (DG) regions of the hippocampus in urethane anesthetized rats showed a significant impairment of LTP after 24- and 48-h SD. Treatment of normal rats with nicotine for 24 or 48 h did not enhance spatial learning and memory or affect magnitude of LTP in the CA1 and DG regions. However, concurrent, acute treatment of rats with nicotine significantly attenuated SD-induced impairment of learning and STM and prevented SD-induced impairment of LTP in the CA1 and DG regions. These results show that acute nicotine treatment prevented the deleterious effect of sleep loss on cognitive abilities and synaptic plasticity.

    The present study included 60 children at the age from 6 to 10 years undergoing a course of out-patient and in-patient treatment of acute rhinosinusitis (ARS). Thirty of these patients were given Myrtol standardised in the dose of 120 mg thrice daily for 7 days, in addition to traditional therapy.With convincing objective data for acute bacterial rhinosinusitis (in accordance with the criteria of EP3OS 2012), antibacterial preparations were prescribed to the children. The remaining patients received either conventional (symptomatic, irrigation) therapy or systemic antimicrobial agents. The analysis of characteristics of the visual-analog scale reflecting the severity of rhinorrhea, basal congestion, and coughing has demonstrated a significant (р<0,05) difference between the two groups of children in terms of manifestations of the clinical symptoms within days 7 and 14 after the onset of the treatment. For basal congestion, the difference was apparent as soon as day 3 after the beginning of therapy. The duration of the treatment with intranasal vasoconstrictive medications used for symptomatic therapy by the patients given Myrtol standardized was 2.2±0.4 days in comparison with 3.6±0.5 days in the control group. None of the patients treated with GeloMyrtol exhibited any adverse reaction attributable to the action of the medication in being studied. The study has demonstrated that using Myrtol standardized for the treatment of the uncomplicated forms of acute rhinosinusitis in children is clinically effective, safe, and convenient method for the management of ARS in children. And it can be recommended for the wide practical application.

    The systematic assessment of residual thromboembolic obstruction after treatment for acute pulmonary embolism (PE) has been understudied. This assessment is of potential clinical importance, should clinically suspected recurrent PE occur, or as tool for risk stratification of cardiopulmonary complications or recurrent venous thromboembolism (VTE). This study aimed to assess the rate of PE resolution and its implications for clinical outcome. In this prospective, multi-center cohort study, 157 patients with acute PE diagnosed by CT pulmonary angiography (CTPA) underwent follow-up CTPA-imaging after six months of anticoagulant treatment. Two expert thoracic radiologists independently assessed the presence of residual thromboembolic obstruction. The degree of obstruction at baseline and follow-up was calculated using the Qanadli obstruction index. All patients were followed-up for 2.5 years. At baseline, the median obstruction index was 27.5 %. After six months of treatment, complete PE resolution had occurred in 84.1 % of the patients (95 % confidence interval (CI): 77.4-89.4 %). The median obstruction index of the 25 patients with residual thrombotic obstruction was 5.0 %. During follow-up, 16 (10.2 %) patients experienced recurrent VTE. The presence of residual thromboembolic obstruction was not associated with recurrent VTE (adjusted hazard ratio: 0.92; 95 % CI: 0.2-4.1).This study indicates that the incidence of residual thrombotic obstruction following treatment for PE is considerably lower than currently anticipated. These findings, combined with the absence of a correlation between residual thrombotic obstruction and recurrent VTE, do not support the routine use of follow-up CTPA-imaging in patients treated for acute PE.

    During the adulticide treatment of Dirofilaria immitis the worms die releasing fragments of parasites and causing pulmonary thromboembolisms which could exacerbate the clinical condition. To determine the utility of acute phase proteins (APPs) to monitor the progression of the treatment, different positive [C-reactive protein (CRP), haptoglobin (hp)] and negative [albumin, paraoxonase-1(PON-1)] APPs were measured in 15 heartworm-infected dogs (5 with high and 10 with low parasite burden) following adulticide treatment. The results showed increased concentrations of CRP, decreased concentrations of haptoglobin and PON-1 in infected dogs before starting the treatment. Progressive but not significant increases were observed in PON-1 activity and albumin concentration along the treatment. After the treatment with doxycycline and ivermectine a decrease in CRP and Hp levels was experienced, which could reflect a reduction of the vascular inflammation caused by the elimination of Wolbachia and reduction of microfilariae. Fifteen days after the first melarsomine injection, marked increases in CRP and Hp were observed, which could be due to pulmonary inflammation and thromboembolism caused by the post-adulticide death of the worms. This increase was greater in dogs with high parasite burden. As the pathology disappeared, there was an improvement in the concentrations of CRP and Hp, returning into reference values in dogs with low parasite burden at the end of the treatment. The measurement of CRP and Hp could be a resource of support to evaluate the magnitude of the post-adulticide complications during the adulticide treatment of D. immitis. PMID:25801227

    There is an increase in reactive oxygen and nitrogen species in cardiomyocytes during myocardial ischemia/reperfusion injury. This leads to oxidative DNA damage and activation of nuclear repair enzymes such as poly(ADP-ribose) polymerase-1 (PARP-1). PARP-1 activation promotes DNA repair under normal conditions. However, excessive activation of PARP-1 leads to cell death. Here we report that PARP-1 enzymatic activity is directly inhibited by minocycline, and we propose that one mechanism of minocycline cardioprotection is due to PARP-1 inhibition. Using cultured adult rat cardiac myocytes, we evaluated the mechanism of minocycline protection in which PARP-1 activation was induced by simulated ischemia/reperfusion (sI/R) injury using oxygen-glucose deprivation. We found an increase in reactive oxygen species production, PARP-1 activation, and PARP-1-mediated cell death after sI/R. Cell death was significantly reduced by the PARP inhibitors DPQ (10 μM) and PJ-34 (500 nM), or by minocycline (500 nM). Cellular NAD+ depletion and poly(ADP-ribose) formation, which are biochemical markers of PARP-1 activation, were also blocked by minocycline. Finally, sI/R led to induction of the mitochondrial permeability transition (MPT), which was prevented by minocycline. Therefore, we propose that the protective effect of minocycline on cardiac myocyte survival is due to inhibition of PARP-1 activity. PMID:20881608

    The pathophysiological basis of sudden cardiac death due to ventricular arrhythmias in acute myocardial infarction has been extensively investigated in experimental as well as in some clinical studies. Numerous clinical studies have been performed with the aim to establish the feasibility of antifibrillatory prophylaxis of sudden cardiac death by pretreatment with antiarrhythmic drugs. Using class I-antiarrhythmic drugs the reported findings were contradictory. While the antiarrhythmic efficacy of Lidocaine and other, newer class I-antiarrhythmic drugs is well established, the antifibrillatory effects of these drugs in the early phase of acute myocardial infarction remain uncertain. In clinical studies with the endpoint of mortality in patients at risk, longterm administration of orally effective class I-antiarrhythmic drugs did not prove to be superior to placebo. However, beta-sympatholytic agents have been shown to reduce mortality in patients at risk in several large clinical studies. The basic mechanism seems to be primarily a reduction in sudden cardiac death which is caused predominantly by ventricular fibrillation. The antifibrillatory properties of beta-blockers was demonstrated as well by a reduction in the number of episodes of ventricular fibrillation. The recognition of patients at risk who profit most from chronic beta-blocker therapy remains the main problem when treatment of numerous low-risk patients is avoided. In the ISIS I-study with Atenolol intravenous administration of a beta-blocker in the early phase of acute myocardial infarction has been shown to be beneficial if hemodynamic monitoring, for example using flow-directed heart catherization is performed. In general this does not apply to the treatment with calciumantagonists, especially with Verapamil and Nifedipine. These drugs do not improve prognosis of acute myocardial ischemia, obviously because of hemodynamic side effects. The antifibrillatory efficacy of Verapamil

    Summary Background We planned to investigate contribution of DWMR to the treatment efficacy with ADC values which were measured in acute and chronic plaque before and after MS treatment. ADC changes in normal appearing white matter (NAWM) in patients with MS and healthy volunteers were also evaluated in this study. Material/Methods 25 patients with MS and 30 healthy subjects with normal brain MR findings were included to our study. Contrast enhancement in plaque was evaluated as an acute, and non-contrast enhancement in plaque was evaluated as a chronic. Also, ADC measurements were performed using the same parameters in NAWM in plaque neighborhood and volunteers. Results were compared with appropriate statistical methods. Results ADC values in acute and chronic plaques were decreased after the treatment, and these reductions were statistically significant for acute plaqus in b500 and for chronic plaques in b500 and b1000. The mean ADC values were measured as 1.53±0.49×10−3 and 1.43±0.58×10−3 in acute plaques and 1.40±0.35×10−3 and 1.34±0.36×10−3 mm2/sec in chronic plaques before and after the treatment. Conclusions We think that DWMR have important role due to quantitative measurement ability in the evaluation of the treatment efficacy of the MS patients with acute attack in addition to contrast-enhanced MR sequence.

    Maternal immune activation can increase the vulnerability of the offspring to develop neuroimmune and behavioral abnormalities in response to stress in puberty. In offspring of immune-challenged mothers, stress-induced inflammatory processes precede the adult onset of multiple behavioral dysfunctions. Here, we explored whether an early anti-inflammatory intervention during peripubertal stress exposure might prevent the subsequent emergence of adult behavioral pathology. We used an environmental two-hit model in mice, in which prenatal maternal administration of the viral mimetic poly(I:C) served as the first hit, and exposure to sub-chronic unpredictable stress during peripubertal maturation as the second hit. Using this model, we examined the effectiveness of the tetracycline antibiotic minocycline (MINO) given during stress exposure to block stress-induced inflammatory responses and to prevent subsequent behavioral abnormalities. We found that combined exposure to prenatal immune activation and peripubertal stress caused significant deficits in prepulse inhibition and increased sensitivity to the psychotomimetic drugs amphetamine and dizocilpine in adulthood. MINO treatment during stress exposure prevented the emergence of these behavioral dysfunctions. In addition, the pharmacological intervention blocked hippocampal and prefrontal microglia activation and interleukin-1β expression in offspring exposed to prenatal infection and peripubertal stress. Together, these findings demonstrate that presymptomatic MINO treatment can prevent the subsequent emergence of multiple behavioral abnormalities relevant to human neuropsychiatric disorders with onset in early adulthood, including schizophrenia. Our epidemiologically informed two-hit model may thus encourage attempts to explore the use of anti-inflammatory agents in the early course of brain disorders that are characterized by signs of central nervous system inflammation during development.

    In this study we analysed the outcome of computer-assisted therapy (CAT) for anomia on eight acute aphasic patients. Since therapy for anomia generally leads to an item-specific effect, the aim of the present study was to investigate whether it is possible to enhance recovery from anomia by increasing the number of treated items. Two periods of five daily written-naming CAT sessions were compared: In one period the CAT included one set of 48 words (single list) and in the other period a double list of 96 items was treated. Seven out of eight patients improved in naming performance for treated items. Overall gains were superior after practising the double list, despite fewer item repetitions. These results suggest that the size of the effect of therapy for anomia depends more on the number of treated items than on the number of repetitions per item. The integration of these results within the framework of studies on intensity is discussed.

    Erlotinib, an epidermal growth factor receptor tyrosine kinase inhibitor, is an oral targeted anticancer drug that is used to treat non-small cell lung cancer (NSCLC). Previous studies have confirmed that erlotinib is safe and is well-tolerated by patients. The most common adverse reactions observed following erlotinib treatment include a rash and mild diarrhea. In the current study, the first case of acute myocardial infarction following one month of treatment with erlotinib in a 63-year-old male NSCLC patient is presented. The present study highlights the importance of clinicians remaining cautious following erlotinib administration. In elderly NSCLC patients and those with a history of coronary heart disease, cardiac function must be carefully monitored following erlotinib treatment so that serious adverse reactions, such as myocardial infarction, may be identified early and treated quickly.

    Abstract Sudden sensorineural hearing loss (SSHL) is an otological emergency defined as a rapid hearing loss, seriously affects patient's social life. To data, no study has reported the treatment by acupuncture alone in the acute phase. In this report, Acupuncture and Moxibustion therapy of excitation-focus transfer is outlined. The patient was a 26-year-old young woman who had an SSHL coupled with ear fullness. The patient had no past medical history, but she had undergone variable emotions and had a history of excessive noise exposure. The patient refused to receive any medicine especially steroids and hyperbaric oxygen therapy. She just only received acupuncture treatment. Her symptoms and outcome measurements were improved every week and completely recovered after the last week. Even though the article presents a single case and is based on self-reports, there are very clear trends on how patients with SSHL responded to acupuncture treatments. PMID:27368045

    Acute kidney injury (AKI) is characterized by an abrupt decline in renal function, resulting in an inability to secrete waste products and maintain electrolyte and water balance, and is associated with high risks of morbidity and mortality. This study retrospectively analyzed clinical data, treatment, and prognosis of 271 hospitalized patients (172 males and 99 females) diagnosed with AKI from December, 2008 to December, 2011. In addition, this study explored the association between the cause of AKI and prognosis, severity and treatment of AKI. The severity of AKI was classified according to the Acute Kidney Injury Network (AKIN) criteria. Renal recovery was defined as a decrease in a serum creatinine level to the normal value. Prerenal, renal, and postrenal causes accounted for 36.5% (99 patients), 46.5% (126 patients) and 17.0% (46 patients), respectively, of the incidence of AKI. Conservative, surgical, and renal replacement treatments were given to 180 (66.4%), 30 (11.1%) and 61 patients (22.5%), respectively. The overall recovery rate was 21.0%, and the mortality rate was 19.6%. Levels of Cl(-), Na(+) and carbon dioxide combining power decreased with increasing severity of AKI. Cause and treatment were significantly associated with AKI prognosis. Likewise, the severity of AKI was significantly associated with cause, treatment and prognosis. Multivariate logistic regression analysis found that respiratory injury and multiple organ dysfunction syndrome (MODS) were associated with AKI patient death. Cause, treatment and AKIN stage are associated with the prognosis of AKI. Respiratory injury and MODS are prognostic factors for death of AKI patients.

    Abstract The optimal treatment for schizoaffective disorder (SCA) is not well established. In this initial 6-month open-label treatment period of a large, multiphase, relapse-prevention study, the efficacy and safety of paliperidone palmitate once-monthly (PP1M) injectable were evaluated in subjects with symptomatic SCA. Subjects with acute exacerbation of SCA (ie, with psychotic and either depressive and/or manic symptoms) were enrolled and treated with PP1M either as monotherapy or in combination with antidepressants or mood stabilizers (combination therapy group). After flexible-dose treatment with PP1M for 13 weeks, stabilized subjects continued into a 12-week fixed-dose PP1M treatment period. A total of 667 subjects were enrolled; 320 received monotherapy and 347 received PP1M as combination therapy; 334 subjects completed the entire 25-week treatment. Statistically significant and clinically meaningful improvements from baseline were observed for all efficacy measures in psychosis (per Positive and Negative Syndrome Scale), mood symptoms (per Young Mania Rating Scale and Hamilton Depression Rating Scale—21 items), and functioning (per Personal and Social Performance Scale) from week 1 to all time points during the 25-week treatment period (P < 0.001). Similar improvements in efficacy measures were observed between subjects receiving monotherapy or combination therapy. Efficacy benefits persisted throughout the 25-week period. The most common adverse events were akathisia (11.1%), injection-site pain (10.6%), and insomnia (10.0%). Paliperidone palmitate once-monthly administered as monotherapy or in combination with mood stabilizers or antidepressants in patients with an acute exacerbation of SCA provided rapid, broad, and persistent reduction in psychotic, depressive, and manic symptoms, as well as improved functioning.

    Heroin addiction is a severe relapsing brain disorder associated with impaired cognitive control, including deficits in attention allocation. The thalamus has a high density of opiate receptors and is critically involved in orchestrating cortical activity during cognitive control. However, there have been no studies on how acute heroin treatment modulates thalamic activity. In a cross-over, double-blind, vehicle-controlled study, 29 heroin-maintained outpatients were studied after heroin and placebo administration, while 20 healthy controls were included for the placebo condition only. Resting-state functional magnetic resonance imaging was used to analyze functional integration of the thalamus by three different resting state analysis techniques. Thalamocortical functional connectivity (FC) was analyzed by seed-based correlation, while intrinsic thalamic oscillation was assessed by analysis of regional homogeneity (ReHo) and the fractional amplitude of low frequency fluctuations (fALFF). Relative to the placebo treatment and healthy controls, acute heroin administration reduced thalamocortical FC to cortical regions, including the frontal cortex, while the reductions in FC to the mediofrontal cortex, orbitofrontal cortex, and frontal pole were positively correlated with the plasma level of morphine, the main psychoactive metabolite of heroin. Furthermore, heroin treatment was associated with increased thalamic ReHo and fALFF values, whereas fALFF following heroin exposure correlated negatively with scores of attentional control. The heroin-associated increase in fALFF was mainly dominated by slow-4 (0.027-0.073 Hz) oscillations. Our findings show that there are acute effects of heroin within the thalamocortical system and may shed new light on the role of the thalamus in cognitive control in heroin addiction. Future research is needed to determine the underlying physiological mechanisms and their role in heroin addiction.

    Thrombolytic treatment for acute myocardial infarction increases the risk of subsequent reocclusion of the infarct related artery. The efficacy and safety of repeat thrombolytic treatment was assessed in 31 patients treated with streptokinase (n = 13) or tissue plasminogen activator (n = 18) a median of five days (1-716) after the first infusion. The indication for readministration was prolonged chest pain with new ST segment elevation. Efficacy was assessed by infarct artery patency at angiography at a median of eight days after readministration in 22 patients and by non-invasive criteria in 23 patients (reperfusion was deemed to be likely if serum creatine kinase was not increased or reached a peak less than 12 hours after infarction). Angiography showed patency of 70% of the infarct arteries after readministration of streptokinase and of 75% after tissue plasminogen activator. The corresponding patency rates assessed noninvasively were 73% and 75%. Reinfarction was prevented in nine (29%) patients. Allergic reactions occurred in four of eight patients who received streptokinase twice (plasmacytosis and acute reversible renal failure developed in one patient). Two patients had major bleeding and two minor bleeding, all after tissue plasminogen activator, and one of them died of cerebral haemorrhage. Repeat thrombolytic treatment results in late patency rates similar to the rates after the initial administration. Allergic reactions were common in those treated twice with streptokinase.

    Electroconvulsive seizures (ECS), one of the most effective treatments of depression, induce mossy fiber sprouting (when assayed by means of synaptic zinc method), and this indicates an increase in the synaptic zinc level in the hippocampus following such therapy. The aim of the present study was to investigate the influence of acute and chronic zinc hydroaspartate administration on the synaptic and total zinc level in the rat hippocampus. We used two methods of zinc determination: (1) zinc-selenium method, which images the pool of synaptic zinc, and (2) flame atomic absorption spectrometry, which assays the total concentration of zinc. Our results indicate that chronic (14 x 65 mg/kg), but not acute, zinc hydroaspartate administration intraperitoneally (i.p.) increases the pool of synaptic zinc in the majority of rat hippocampal layers (by 72-190%), except for the stratum moleculare and stratum radiatum CA, and perforant path DG. On the other hand, no changes were found in total hippocampal zinc level, measured by flame atomic absorption spectrometry. These data suggest that chronic zinc treatment increases the pool of synaptic zinc in the hippocampus, and this effect is similar to that observed following chronic ECS treatment. The measurement of zinc concentration in the whole hippocampus by the flame atomic absorption spectrometry method is not sensitive enough to detect such subtle alteration. PMID:16674928

    Recent progress in the treatment of primary headaches has made available specific, effective and safe medications for these disorders, which are widely spread among the general population. One of the negative consequences of this undoubtedly positive progress is the risk of drug-drug interactions. This review is the first in a two-part series on pharmacokinetic drug-drug interactions of headache medications. Part I addresses acute treatments. Part II focuses on prophylactic treatments. The overall aim of this series is to increase the awareness of physicians, either primary care providers or specialists, regarding this topic. Pharmacokinetic drug-drug interactions of major severity involving acute medications are a minority among those reported in literature. The main drug combinations to avoid are: i) NSAIDs plus drugs with a narrow therapeutic range (i.e., digoxin, methotrexate, etc.); ii) sumatriptan, rizatriptan or zolmitriptan plus monoamine oxidase inhibitors; iii) substrates and inhibitors of CYP2D6 (i.e., chlorpromazine, metoclopramide, etc.) and -3A4 (i.e., ergot derivatives, eletriptan, etc.), as well as other substrates or inhibitors of the same CYP isoenzymes. The risk of having clinically significant pharmacokinetic drug-drug interactions seems to be limited in patients with low frequency headaches, but could be higher in chronic headache sufferers with medication overuse.

    Acute compartment syndrome (ACS) of the foot represents a rare complication following trauma of the lower extremity. Early diagnosis and treatment are necessary to prevent poor outcome. The study was conducted to describe etiology and treatment of foot ACS. In the current study, patients diagnosed with and treated for ACS between 1st December 2000 and 30th September 2007 were included. Mechanism of injury, additional injuries and treatment was analyzed. We included 31 patients (21 males) with a mean age of 33.8 ± 16.9 years. Most injuries were caused by a motor vehicle accident, while nearly 20 % occurred after a low-energy mechanism. Multiple injuries with a mean ISS of 19.5 ± 11.0 were present in 14 patients. Superficial infections occurred in 6 feet, while a deep infection only developed in one patient. Acute compartment syndrome of the foot has a low incidence. A thorough clinical examination in patients on risk is required to provide timely diagnosis and adequate surgical decompression.

    The objective of the study was to compare cutaneous treatments (heat, papain and vinegar) for acute jellyfish (Carybdea alata) stings. Healthy adult volunteer subjects received a single-tentacle jellyfish sting on each forearm. One forearm was treated with hot-water immersion (40-41 degrees C). This was compared with the other forearm, which was randomized to a comparison treatment of papain meat tenderizer or vinegar. Pain was measured at 0, 2, 4, 6, 8, 10, 15, and 20 minutes using a 10-cm visual analog scale (VAS). For 25 subject runs, the average VAS scores at t = 0 were 3.6 cm (hot water) and 3.7 cm (comparison treatment). At t = 4 minutes (2 minutes after treatment had started), the differences between hot-water and comparison group VAS scores were 2.1 cm versus 3.2 cm, respectively. The mean difference between hot-water and comparison treatments was 1.1 cm (95% confidence interval, 0.6 to 1.6). At t = 20 minutes (the end of the study period), the differences between hot-water and comparison group VAS scores were 0.2 cm versus 1.8 cm, respectively. The mean difference between hot-water and comparison treatments was 1.6 cm (95% confidence interval, 0.9 to 2.3). This study suggests that the most efficacious initial treatment for C alata jellyfish envenomation is hot-water immersion to the afflicted site. PMID:12442242

    Anti-PD-1 inhibitors have significant activity in metastatic melanoma. Responses often occur early and may be sustained. The optimal duration of treatment with these agents is unknown. Here, we report the case of a 51-year-old woman treated with pembrolizumab, as part of the Keynote-001 trial, as first-line treatment for metastatic disease. She experienced a complete response after 13.8 months of treatment with no adverse events. One month after the last drug infusion and 18 months from starting treatment, the patient presented with eosinophilic fasciitis. She then developed acute confusion and weakness, thought to be due to intracranial vasculitis. High-dose steroids were initiated with resolution of the fasciitis. Aspirin was commenced for presumed vasculitis with resolution of the neurologic symptoms. To our knowledge, there are no previous reports of eosinophilic fasciitis or cerebral vasculitis due to anti-PD-1 agents. This case demonstrates that toxicity may occur in association with pembrolizumab treatment after a prolonged period of treatment without toxicity. Future trials should explore the optimal duration of treatment with pembrolizumab.

    Background. Xyloglucan, a film-forming agent, improves intestinal mucosa resistance to pathologic damage. The efficacy, safety, and time of onset of the antidiarrheal effect of xyloglucan were assessed in children with acute gastroenteritis receiving oral rehydration solution (ORS). Methods. This randomized, controlled, open-label, parallel-group, multicenter, clinical trial included children (3 months–12 years) with acute gastroenteritis of infectious origin. Children were randomized to xyloglucan and ORS, or ORS only, for 5 days. Diarrheal symptoms, including stool number/characteristics, and safety were assessed at baseline and after 2 and 5 days and by fulfillment of a parent diary card. Results. Thirty-six patients (58.33% girls) were included (n = 18/group). Patients receiving xyloglucan and ORS had better symptom evolution than ORS-only recipients, with a faster onset of action. At 6 hours, xyloglucan produced a significantly greater decrease in the number of type 7 stools (0.11 versus 0.44; P = 0.027). At days 3 and 5, xyloglucan also produced a significantly greater reduction in types 6 and 7 stools compared with ORS alone. Xyloglucan plus ORS was safe and well tolerated. Conclusions. Xyloglucan is an efficacious and safe option for the treatment of acute gastroenteritis in children, with a rapid onset of action in reducing diarrheal symptoms. This study is registered with ISRCTN number 65893282. PMID:27212943

    The relationship between pharyngeal infections, such as tonsillitis and pharyngitis, caused by group A beta-hemolytic streptococci (BHSA) and acute rheumatic fever (ARF) is a well-established fact confirmed by numerous studies carried out along the following lines: epidemiological, immunological, therapeutic, and prophylactic. The currently available data provide an opportunity to discuss the existence of «rheumatogenic» BHSA strains exhibiting a number of characteristic clinical and morphological properties. According to the current recommendations penicillins remain the means of first-line therapy for the treatment of acute forms of BHSA-induced tonsillitis and pharyngitis, whereas the macrolides should be applied only as the alternative medications in the patients with intolerance to beta-lactam antibiotics. This article contains characteristics of BHSA-carrier state and the principal indications for the prescription of antibiotics to the patients with these conditions. The key principle of secondary medicamental prophylaxis of acute respiratory infections are expounded along with the main fines of future research on the problems associated with BHSA-induced pharyngeal infections.

    Summary Purpose hamstring injury is the most common musculoskeletal disorder and one of the main causes of missed sporting events. Shortening the time to return to play (TTRTP) is a priority for athletes and sports medicine practitioners. Hypothesis platelet-rich plasma (PRP) injection at the site of severe acute hamstring injury increases the healing rate and shortens the TTRTP. Study design Cohort study. Methods all patients with ultrasonography and MRI evidence of severe acute hamstring injury between January 2012 and March 2014 were offered PRP treatment. Those who accepted received a single intramuscular PRP injection within 8 days post-injury; the other patients served as controls. The same standardized rehabilitation program was used in both groups. A physical examination and ultrasonography were performed 10 and 30 days post-injury, then a phone interview 120 days post-injury, to determine the TTRTP at the pre-injury level. Results of 34 patients, 15 received PRP and 19 did not. Mean TTRTP at the pre-injury level was 50.9±10.7 days in the PRP group and 52.8±15.7 days in the control group. The difference was not statistically significant. Conclusion a single intramuscular PRP injection did not shorten the TTRTP in sports people with severe acute hamstring injuries. PMID:26958537

    The frequency and causes of treatment-related deaths (TRD) in second complete remission (CR2) in acute myeloid leukaemia (AML) were investigated in a historical, prospective cohort study of 429 children included in the Nordic Society of Paediatric Haematology and Oncology (NOPHO)-AML-88 and -93 trials. Relapse occurred in 158 children (39%). Seventeen (18%) of the 96 patients entering CR2 suffered TRD. The main causes were infection (59%) and complications from graft-versus-host disease (22%). Fourteen (82%) of 17 TRDs occurred in children undergoing haematopoietic stem cell transplantations (HSCT). Optimal supportive care after HSCT is essential, and studies on risk factors for TRD are needed.

    In the last 60 years, there have been substantial advances regarding the diagnosis and treatment of patients with acute and chronic leukemia in Mexico. Immunologic and molecular classifications of these diseases have improved both diagnosis and therapeutic capabilities. Although the pace of diagnostic and therapeutic advances has been slower compared with developed countries, Mexico is at the forefront among developing countries. Supporting research in these fields is expected to enhance the generation of new knowledge and improve the care of patients suffering from these diseases. PMID:27557388

    Our ability to define appropriate molecular targets for preclinical development and develop better methods needs to be improved, to determine the clinical value of novel acute respiratory distress syndrome (ARDS) agents. Clinical trials must have realistic sample sizes and meaningful end points and use the available observation and meta-analytical data to inform design. Biomarker-driven studies or defined ARDS subsets should be considered to categorize specific at-risk populations most likely to benefit from a new treatment. Innovations in clinical trial design should be pursued to improve the outlook for future interventional trials in ARDS.

    Background: Second-generation antipsychotics, approved for the treatment of mania, are associated with adverse effects such as weight gain and metabolic disorders. Aripiprazole, a recently introduced second-generation antipsychotic, are thought to account for its low propensity for weight gain, metabolic disturbances and sedation. The purpose of this study was to investigate the effect of risperidone versus aripiprazole in the treatment of acute mania. Materials and Methods: Fifty patients with acute episodes of mania were enrolled in this study, and they were randomly assigned into a risperidone group of 24 cases and an aripiprazole group of 26 cases. In group A, aripiprazole with a dose of 5-30 mg/day and in group B, risperidone with a dose of 2-8 mg/day was given to patients. The average dose of aripiprazole was 27 mg/day, and the average dose of risperidone was 6 mg/day. The effects of each drug for the treatment of acute mania were assessed on the 1st day of admission and on days 2, 4, 6, 8 and at weeks 2, 4 and 6 after therapy using the young mania rating scale (YMRS) and at the baseline and on weeks 3 and 6 after admission using the clinical global impression (CGI) scale. Results: The mean age of the group of risperidone was 34 ± 8.6 years and in a group of aripiprazole it was 34 ± 9.1 years (P = 0.83). Comparison of YMRS scores over the period of 6 weeks revealed a statistically significant difference in both groups (P < 0.0001). There was also a statistically significant difference in YMRS scores between risperidone and aripiprazole at day 8 (P = 0.026) and weeks 2 (P = 0.035) and 4 (P = 0.042). There was also a statistically significant difference in CGI-Severity scale score at weeks 3 (P = 0.003) and 6 (P = 0.000) and in CGI-Improvement scale score at weeks 3 (P = 0.005) and 6 (P = 0.002). The most common side-effect observed in both groups was headache (0%15/4 in aripiprazole vs. %16/7 in risperidone) Conclusion: Aripiprazole that is readily available

    STUDY OBJECTIVE--The relation between a history of disorders suggestive of acute otitis media, symptoms, and findings of an examination of the tympanic membrane and doctors' certainty of diagnosis. Also, to examine differences in prescribing habits for acute otitis media among doctors from different countries. DESIGN--Questionnaires were completed by participating doctors for a maximum of 15 consecutive patients presenting with presumed acute otitis media. SETTING--General practices in Australia, Belgium, Great Britain, Israel, The Netherlands, New Zealand, Canada, Switzerland, and the United States. PATIENTS--3660 Children divided into the three age groups 0-12 months, 13-30 months, and greater than or equal to 31 months. MAIN OUTCOME MEASURES--General practitioners' responses to questions on their diagnostic certainty and resolution of patients' symptoms after two months. RESULTS--The diagnostic certainty in patients aged 0-12 months was 58.0%. This increased to 66.0% in those aged 13-30 months and 73.3% in those aged greater than or equal to 31 months. In all age groups diagnostic certainty was positively associated with the finding of a tympanic membrane that was discharging pus or bulging. Redness of the membrane and pain were also associated with certainty in patients aged 13-30 months, and a history of decreased hearing or recent upper respiratory infection was positively associated in patients aged greater than or equal to 31 months. The proportion of patients prescribed antibiotics varied greatly among the countries, from 31.2% in The Netherlands to 98.2% in both Australia and New Zealand, as did the duration of treatment. Patients who did not take antibiotics had a higher rate of recovery than those who did; the rate of recovery did not differ between different types of antibiotic. CONCLUSIONS--Doctors' certainty of diagnosis of acute otitis media was linked to patient's age. Improved criteria or techniques for diagnosing acute otitis media, especially in

    Aortic valve injury due to blunt trauma is rare and often difficult to diagnose. Therefore, most reported cases are operated on months or years after initial injury. Reported below is the case of a 55-year-old male, who was involved in a head-on collision with a bus. He was transported to Tsukuba Medical Center by ambulance, 34 minutes after the accident. The patient presented acute shock without obvious evidence of hemorrhaging. On physical examination a murmur was detected. The murmur was evaluated by Doppler echocardiography and revealed aortic regurgitation. On further physical examination he had gross hematuria and intratracheal bleeding. Computerized tomography (CT) showed evidence of contusions to his lungs, liver, and kidneys. The individual was diagnosed with an aortic valve injury, causing aortic insufficiency. It was necessary to continuously monitor the patients' hemodynamic state, assessing when conditions to operate were most favorable. However, in the hyper-acute phase the bleeding is difficult to control. We waited for his platelet count to recover before operating on the fifth day. When the patient underwent valve repair using extracorporeal circulation (ECC), aprotinin was added to the procedure. The surgery revealed a large laceration on the right coronary cusp of the aortic valve. Repair to the valve was impossible, so replacement of the aortic valve was required. A Carbomedics mechanical valve (phi 21 mm) was inserted. The patient did well after surgery, and eventually returned to work. To date, in Japan, there are eleven such cases of aortic valve injury on file. However, this is the first reported case that involved operating during the acute phase. This case demonstrates that, with careful evaluation of coexisting injuries and control of bleeding, successful treatment of aortic valve injury using ECC is possible, even in the acute phase.

    Postoperative cognitive dysfunction (POCD), mainly characterized by short-term decline of learning and memory, occurs after operations under anesthesia. However, the underlying mechanisms are poorly understood. The μ-opioid receptors (MOR) are highly expressed in interneurons of hippocampus, and is believed to be critical for the dysfunction of synaptic plasticity between hippocampal neurons. Therefore, we investigated the effect of fentanyl, a strong agonist of MOR and often used for anesthesia and analgesia in clinical settings, on hippocampal synaptic plasticity in the Schaffer-collateral CA1 pathway during acute exposure and washout in vitro. Our results revealed that acute fentanyl exposure (0.01, 0.1, 1 μM) dose-dependently increased the field excitatory postsynaptic potentials (fEPSPs), which was prevented by pre-administration of picrotoxin (50 μM) or MOR antagonist D-Phe-Cys-Tyr-D-Trp-Orn-Thr-Phe-Thr-NH2 (CTOP, 10 μM). While fentanyl exposure-increased fEPSPs amplitude was prevented by picrotoxin [an inhibitor of γ-aminobutyric acid receptor (GABAR)] treatment or fentanyl washout, pretreatment of picrotoxin failed to prevent the fentanyl-impaired long-term potentiation (LTP) of synaptic strength as well as the fentanyl-enhanced long-term depression (LTD). These results demonstrated that fentanyl acute exposure and washout increases hippocampal excitability in the Schaffer-collateral CA1 pathway, depending on disinhibiting interneurons after MOR activation. In addition, fentanyl acute exposure and washout modulated synaptic plasticity, but the inhibitory activation was not critical. Elucidating the detailed mechanisms for synaptic dysfunction after fentanyl exposure and washout may provide insights into POCD generation after fentanyl anesthesia. PMID:26578961

    The recurrence rate for acute appendicitis treated nonoperatively varies between studies. Few studies have adequately evaluated the management of these patients when appendicitis recurs. We aimed to explore the recurrence rate and management of patients with acute appendicitis that were first treated nonoperatively.We identified patients in the Taiwan National Health Insurance Research Database who were hospitalized due to acute appendicitis for the first time between 2000 and 2010 and received nonsurgical treatment. The recurrence and its management were recorded. Data were analyzed to access the risk factors for recurrence and factors that influenced the management of recurrent appendicitis.Among the 239,821 patients hospitalized with acute appendicitis for the first time, 12,235 (5.1%) patients were managed nonoperatively. Of these, 864 (7.1%) had a recurrence during a median follow-up of 6.5 years. Appendectomy was performed by an open and laparoscopic approach in 483 (55.9%) and 258 (29.9%) patients, respectively. The remaining 123 (14.2%) patients were again treated nonsurgically. Recurrence was independently associated with young age, male sex, percutaneous abscess drainage, and medical center admission by multivariable analysis. In addition, age <18, a (CCI) <2, medical center admission, and a longer time to recurrence were correlated with using laparoscopy to treat recurrence. Neither type of appendicitis, percutaneous abscess drainage, nor length of first time hospital stay had an influence on the selection of surgical approach.In conclusion, a laparoscopic appendectomy can be performed in recurrent appendicitis cases, and its application may not be related to previous appendicitis severity.

    Objective We examine remission rate probabilities, recovery rates, and residual symptoms across 36 weeks in the Treatment for Adolescents with Depression Study (TADS). Method TADS, a multisite clinical trial, randomized 439 adolescents with major depressive disorder (MDD) to 12 weeks of treatment to fluoxetine (FLX), cognitive behavioral therapy (CBT), their combination (COMB), or pill placebo (PBO). The PBO group, treated openly after week 12, was not included in the subsequent analyses. Treatment differences in remission rates and probabilities of remission over time are compared. Recovery rates in remitters at week 12 (acute phase remitters) and week 18 (continuation phase remitters) are summarized. We also examined whether residual symptoms at the end of 12 weeks of acute treatment predicted later remission. Results At Week 36, the estimated remission rates for intention-to-treat cases were: COMB: 60%, FLX: 55%; CBT: 64%; overall: 60%. Paired comparisons reveal that at week 24 all active treatments converge on remission outcomes. The recovery rate at Week 36 was 65% for acute phase remitters and 71% for continuation phase remitters, with no significant between-treatment differences in recovery rates. Residual symptoms at the end of acute treatment predicted failure to achieve remission at weeks 18 and 36. Conclusions The majority of depressed adolescents in all three treatment modalities achieved remission at the end of nine months of treatment. PMID:19127172

    The aims of this study were to assess that the effects of bone marrow mesenchymal stem cells (BMSCs) combination with minocycline improve spinal cord injury (SCI) in rat model. In the present study, the Wistar rats were randomly divided into five groups: control group, SCI group, BMSCs group, Minocycline group and BMSCs + minocycline group. Basso, Beattie and Bresnahan (BBB) test and MPO activity were used to assess the effect of combination therapy on locomotion and neutrophil infiltration. Inflammation factors, VEGF and BDNF expression, caspase-3 activation, phosphorylation-p38MAPK, proNGF, p75NTR and RhoA expressions were estimated using commercial kits or western blot, respectively. BBB scores were significantly increased and MPO activity was significantly undermined by combination therapy. In addition, combination therapy significantly decreased inflammation factors in SCI rats. Results from western blot showed that combination therapy significantly up-regulated the protein of VEGF and BDNF expression and down-regulated the protein of phosphorylation-p38MAPK, proNGF, p75NTR and RhoA expressions in SCI rats. Combination therapy stimulation also suppressed the caspase-3 activation in SCI rats.

    Objective Many studies have supported the role of protein kinase C (PKC) inhibitors in the physiopathology and treatment of bipolar disorder in adults. Tamoxifen is one of the drugs with the effect of PKC inhibition. This study aimed to determine the effect of tamoxifen on the rate of improvement mania symptoms in the sample of children and adolescents with acute mania. Materials & Methods In this randomized, placebo-controlled clinical trial study, registered in www.irct.ir with the code of IRCT201410126418N3, overall 44 patients with bipolar disorder with acute manic episode were randomly assigned into treatment and control groups. The serum levels of lithium and tamoxifen among the participants in the treatment groups were 0.8 -1.1 mg and 20-40 mg per day respectively. Serum level of lithium among participants in the control group was similar. The main comparisons were made based on the Young Mania Rating Scale (YMRS) and Children Depression Inventory (CDI) scores of the participants at baseline and at the end of each study week. The pharmacological side effects of serum level of lithium were examined weekly. Analysis of Covariance(ANCOVA) test was used for the statistical analysis. Results There was no difference in the baseline score of YMRS and CDI in the treatment and control groups while a statistical significant difference (P < 0.05) in these scores was found between and within the groups. Conclusion The addition of tamoxifen to lithium causes a significant difference in reducing the symptoms of mania and depression in the treatment group compared to the control group. PMID:27247580

    Abstract Conclusion: Daily intake of 480 mg of BNO 1016 for 15 days is an effective treatment in acute viral rhinosinusitis. Objectives: The pooled efficacy data of two similar randomized placebo-controlled clinical trials were analyzed. Safety was evaluated on the basis of the individual trials. Methods: The efficacy analysis was based on 589 patients. Treatment was performed orally with either 3 × 160 mg BNO 1016 (n = 294) or 3 × placebo (n = 295) for 15 days. In both trials patients underwent five visits to the investigational sites. Symptoms were evaluated according to the EPOS 2012 guideline. Ultrasonography was used to confirm the diagnosis at onset of treatment and the remission of symptoms at the last visit. Efficacy was evaluated by the investigator as the mean major symptom score (MSS) at the end of treatment (visit 5, day 14). Patients reported symptoms and social/emotional consequences of rhinosinusitis using a quality of life questionnaire (SNOT-20 GAV). Results: MSS improved during the treatment period by a mean of 10.02 ± 1.61 score points to 2.47 ± 2.55 for BNO 1016 and of 9.87 ± 1.52 to 3.63 ± 3.63 for placebo. Differences between treatment groups at end of therapy (1.16 ± 3.14 score points; p < 0.0001) and patient-assessed quality of life (p = 0.0015) were statistically significant in favor of BNO 1016.

    The purpose of this randomized study was to evaluate the early effect of the treatment of acute acoustic trauma (AAT) with steroids and piracetam in a sample of 52 young soldiers who were exposed to intense gunfire noise (G3 rifle). These patients were divided into three groups: (1) group A (20 patients) in which the treatment began within the first hour after the AAT, (2) group B (17 patients) in which the treatment started more than 1 h later and less than 16 h after the AAT and (3) group C (15 patients) in which the treatment began after 24 h or more. One month after the treatment onset, 36 (69%) patients of all the groups showed hearing improvement (complete-partial recovery) in the pure tone audiometry. The greater number of patients who showed complete recovery after AAT was noted in group A (65%) compared to group B (23.5%) and C (13.3%). Moreover, in group A, in the final audiogram, the averaged hearing threshold was statistically better (P < 0.001) than that of groups B and C. In spite of the lack of control group, our data demonstrated the possible effectiveness of the immediate onset of treatment of AAT. PMID:18463885

    IL-1 generation by mononuclear phagocytes, IL-4 production by Th2 lymphocytes and IgE levels in serum were measured in eight patients with acute fasciolosis and seven patients in the chronic stage of the disease before and after triclabendazole treatment. Results were compared with those of a control group of ten individuals. The monocytes and lymphocytes from patients with acute and chronic fasciolosis produced significantly lower levels of IL-1 and IL-4 respectively, particularly in the chronic phase of the disease, as compared to the control. A significant increase in IgE level in both acute and chronic fasciolosis was observed. The level was significantly higher in acute as compared to chronic cases. After treatment with triclabendazole IL-1, IL-4 and IgE levels moved towards the control indicating obvious improvement in the immunological responses of the patients.

    Approximately 26.8% of China's land area has an elevation of 3000 m above sea level or higher. Because of recent demands for economic development and new construction in highland areas, many people have relocated from the plains to high plateau regions and have to face the possibility of contracting acute mountain sickness. Therefore, prevention and treatment strategies are necessary to reduce the incidence of acute mountain sickness in people who rapidly ascend to plateau areas. This paper describes the Chinese experience when large numbers of people moved to the plateau and the steps that were taken to deal with this illness. These steps included implementing basic prevention measures, increasing medical awareness among populations ascending to high altitudes, and installing standardized medical management systems to prevent and treat acute mountain sickness before, during, and after ascent. The incidence of acute mountain sickness can be reduced by improving prevention and treatment and by implementing the recommendations described in this manuscript.

    Purpose: To evaluate the safety and efficacy of neurointerventional procedures in acute stroke patients performed by a team of vascular interventional radiologists in close cooperation with diagnostic neuroradiologists and stroke neurologists and to compare the results with those of previous reports from centres with specialised interventional neuroradiologists. Material and Methods: A total of 39 patients with acute ischemic stroke due to large-vessel occlusion not responding to or not eligible for intravenous thrombolysis were treated with either intra-arterial thrombolysis or mechanical thrombectomy (Penumbra System or solitaire FR thrombectomy system, respectively) and included in our prospective study. Outcomes were measured using the modified Rankin scale after 90 days, and recanalization was assessed by thrombolysis using the myocardial infarction score. Results: Mean patient age was 68.3 {+-} 14.2 years; the average National Institutes of Health Stroke Scale score at hospital admission was 17.2 (SD = 6.2 [n = 38]). Successful recanalization was achieved in 74.4 % of patients. Median time from clinical onset to recanalization was 5 h 11 min. Procedure-related complications occurred in 5 % of patients, and 7.5 % had a symptomatic intracerebral hemorrhage. Of the patients, 22.5 % died within the first 90 postprocedural days, 5 % of these from cerebral causes. Patients who were successfully recanalized had a clinical better outcome at follow-up than those in whom treatment failed. Of the patients, 35.9 % had an mRS score {<=}2 after 90 days. Conclusion: Our results are in line with those in the published literature and show that a treatment strategy with general interventional radiologists performing neurointerventional procedures in acute stroke patients with large vessel occlusions can be achieved to the benefit of patients.

    Abstract With no currently available drug treatment for spinal cord injury, there is a need for additional therapeutic candidates. We took the approach of repositioning existing pharmacological agents to serve as acute treatments for spinal cord injury and previously found imatinib to have positive effects on locomotor and bladder function in experimental spinal cord injury when administered immediately after the injury. However, for imatinib to have translational value, it needs to have sustained beneficial effects with delayed initiation of treatment, as well. Here, we show that imatinib improves hind limb locomotion and bladder recovery when initiation of treatment was delayed until 4 h after injury and that bladder function was improved with a delay of up to 24 h. The treatment did not induce hypersensitivity. Instead, imatinib-treated animals were generally less hypersensitive to either thermal or mechanical stimuli, compared with controls. In an effort to provide potential biomarkers, we found serum levels of three cytokines/chemokines—monocyte chemoattractant protein-1, macrophage inflammatory protein (MIP)-3α, and keratinocyte chemoattractant/growth-regulated oncogene (interleukin 8)—to increase over time with imatinib treatment and to be significantly higher in injured imatinib-treated animals than in controls during the early treatment period. This correlated to macrophage activation and autofluorescence in lymphoid organs. At the site of injury in the spinal cord, macrophage activation was instead reduced by imatinib treatment. Our data strengthen the case for clinical trials of imatinib by showing that initiation of treatment can be delayed and by identifying serum cytokines that may serve as candidate markers of effective imatinib doses.

    Background and Purpose Calcium/calmodulin-dependent protein kinase IIδ (CaMKIIδ) is an important regulator of cardiac contractile function and dysfunction and may be an unwanted secondary target for anti-cancer drugs such as sunitinib and imatinib that have been reported to alter cardiac performance. This study aimed to determine whether anti-cancer kinase inhibitors may affect CaMKII activity and expression when administered in vivo. Experimental Approach Cardiovascular haemodynamics in response to acute and chronic sunitinib treatment, and chronic imatinib treatment, were assessed in guinea pigs and the effects compared with those of the known positive and negative inotropes, isoprenaline and verapamil. Parallel studies from the same animals assessed CaMKIIδ expression and CaMKII activity following drug treatments. Key Results Acute administration of sunitinib decreased left ventricular (LV) dP/dtmax. Acute administration of isoprenaline increased LVdP/dtmax dose-dependently, while LVdP/dtmax was decreased by verapamil. CaMKII activity was decreased by acute administration of sunitinib and was increased by acute administration of isoprenaline, and decreased by acute administration of verapamil. CaMKIIδ expression following all acute treatments remained unchanged. Chronic imatinib and sunitinib treatments did not alter fractional shortening; however, both CaMKIIδ expression and CaMKII activity were significantly increased. Chronic administration of isoprenaline and verapamil decreased LV fractional shortening with parallel increases in CaMKIIδ expression and CaMKII activity. Conclusions and Implications Chronic sunitinib and imatinib treatment increased CaMKIIδ expression and CaMKII activity. As these compounds are associated with cardiac dysfunction, increased CaMKII expression could be an early indication of cellular cardiotoxicity marking potential progression of cardiac contractile dysfunction.

  8. Histone deacetylases: a common molecular target for differentiation treatment of acute myeloid leukemias?

    Recent discoveries have identified key molecular events in the pathogenesis of acute promyelocytic leukemia (APL), caused by chromosomal rearrangements of the transcription factor RAR (resulting in a fusion protein with the product of other cellular genes, such as PML). Oligomerization of RAR, through a self-association domain present in PML, imposes an altered interaction with transcriptional co-regulators (NCoR/SMRT). NCoR/SMRT are responsible for recruitment of histone deacetylases (HDACs), which is required for transcriptional repression of PML-RAR target genes, and for the transforming potential of the fusion protein. Oligomerization and altered recruitment of HDACs are also responsible for transformation by the fusion protein AML1-ETO, extending these mechanisms to other forms of acute myeloid leukemias (AMLs) and suggesting that HDAC is a common target for myeloid leukemias. Strikingly, AML1-ETO expression blocks retinoic acid (RA) signaling in hematopoietic cells, suggesting that interference with the RA pathway (genetically altered in APL) by HDAC recruitment may be a common theme in AMLs. Treatment of APLs with RA, and of other AMLs with RA plus HDAC inhibitors (HDACi), results in myeloid differentiation. Thus, activation of the RA signaling pathway and inhibition of HDAC activity might represent a general strategy for the differentiation treatment of myeloid leukemias.

    Zinc is a trace metal with in vitro activity against rhinovirus, the major etiologic agent in acute upper respiratory tract infections (URIs). A previous trial of zinc gluconate supported its efficacy in treating URIs, but the effectiveness of blinding was uncertain. We conducted a prospective randomized trial of zinc gluconate versus a taste-matched placebo of sucrose octaacetate. Lozenges containing either 23 mg of elemental zinc or placebo were taken every 2 h. Eleven URI symptoms were rated daily on a scale of 0 (not present) to 3 (severe). Duration of illness, reflected in the proportion of subjects remaining symptomatic on each day, was not significantly reduced (maximum difference of 12.6% on day 7, P = 0.09; 95% confidence interval, -6 to 31%) by either treatment. Severity of illness, assessed by using a summed severity score, was reduced incrementally by 7 to 8% on days 5 to 7 (P = 0.02) in subjects taking zinc. Adverse effects, mostly nausea and altered taste, were reported by 50% of subjects taking zinc. We conclude that while zinc gluconate may produce a small reduction in overall severity of symptoms, this is not clinically significant. Given the additional high incidence of adverse effects, zinc gluconate cannot be recommended for use in the treatment of acute URIs. PMID:2665639

    Objective. To evaluate if early cholecystectomy (EC) is the most appropriate treatment for acute cholecystitis compared to delayed cholecystectomy (DC). Patients and Methods. A retrospective cohort study of 1043 patients was carried out, with a group of 531 EC cases and a group of 512 DC patients. The following parameters were recorded: (1) postoperative hospital morbidity, (2) hospital mortality, (3) days of hospital stay, (4) readmissions, (5) admission to the Intensive Care Unit (ICU), (6) type of surgery, (7) operating time, and (8) reoperations. In addition, we estimated the direct cost savings of implementing an EC program. Results. The overall morbidity of the EC group (29.9%) was significantly lower than the DC group (38.7%). EC demonstrated significantly better results than DC in days of hospital stay (8.9 versus 15.8 days), readmission percentage (6.8% versus 21.9%), and percentage of ICU admission (2.3% versus 7.8%), which can result in reducing the direct costs. The patients who benefited most from an EC were those with a Charlson index > 3. Conclusions. EC is safe in patients with acute cholecystitis and could lead to a reduction in the direct costs of treatment. PMID:27803512

    Treatment of acute myeloid leukemia (AML) in the elderly has always been a challenging task. Acute myeloid leukemia in older adults is a biologically and clinically distinct entity. Based on analysis of cytogenetic and molecular data, it is known that leukemic cells in older patients are intrinsically resistant to standard chemotherapy. Due to comorbid disease and impaired bone marrow stem cell reserve, older adults tolerate myelosuppressive chemotherapy poorly, with a treatment-related mortality rate of 25%. In spite of various available targeted therapies, the overall survival has not improved dramatically in the past decade. The ideal post remission regimen in this population has always been a matter of debate. Standard allogeneic bone marrow transplantation is too dangerous to be considered as a mean to eradicate minimal residual disease after remission is obtained and myelointensive chemotherapy is not a beneficial post-remission strategy in this age cohort. These disappointing results call for more effective and less toxic therapeutic options. The advent of non-myeloablative regimens has shown some prospects in select group of patients with good performance status. This review focuses on current therapeutic options available in this group of patients. PMID:20084771

    This is the consensus document on acute otitis media (AOM) of the Sociedad Española de Infectología Pediatrica (SEIP), Sociedad Española de Pediatría Extrahospitalaria y Atención Primaria (SEPEAP), Sociedad Española de Urgencias Pediátricas (SEUP) and Asociación Española de Pediatría de Atención Primaria (AEPAP). It discusses the aetiology of the disease and its potential changes after the introduction of the pneumococcal 7-valent, 10-valent and 13-valent vaccines. A proposal is made based on diagnostic classification of otitis media as either confirmed or likely. AOM is considered confirmed if 3 criteria are fulfilled: acute onset, signs of occupation of the middle ear (or otorrhea) and inflammatory signs or symptoms, such as otalgia or severe tympanic hyperaemia. Oral amoxicillin is the antibiotic treatment of choice (80mg/kg/day divided every 8hours). Amoxicillin-clavulanate (80mg/kg/day) is indicated in the following cases: when the child is under 6 months, in infants with severe clinical manifestations (fever>39°C or severe pain), there is family history of AOM sequels, and after amoxiciline treatment failure.

    Objective Cancer treatment is reported to be stressful, and patients diagnosed with hematologic cancers often exhibit higher levels of anxiety and emotional distress than individuals with other malignancies. Management of these symptoms in patients with hematologic cancer presents significant challenges, as many of them are in and out of the hospital while undergoing high dose chemotherapy. Oncology patients use complementary modalities such as therapeutic massage in an attempt to alleviate disease and treatment-related symptoms, including anxiety and emotional distress. In the current study, the feasibility of a novel massage intervention delivered over the continuum of care, as well as assessment of the immediate and cumulative effects of massage, was examined in patients with acute myelogenous leukemia. Methods A mixed-methods, unmasked, prospective, randomized study was conducted with two groups: a usual care alone control group and a massage therapy intervention plus usual care group. Results Significant improvements in levels of stress and health-related quality of life were observed in the massage therapy group versus the usual care alone group, after adjusting for anxiety level, including both immediate and cumulative effects of massage. Conclusions While the findings of the current study regarding acceptability, feasibility, and potential efficacy of therapeutic massage as a complementary health-enhancing intervention in patients diagnosed with acute myelogenous leukemia are very promising, the relatively small size of the study sample limits generalizability.

    Injury to lung epithelial cells has a role in multiple lung diseases. We previously identified mitsugumin 53 (MG53) as a component of the cell membrane repair machinery in striated muscle cells. Here we show that MG53 also has a physiological role in the lung and may be used as a treatment in animal models of acute lung injury. Mice lacking MG53 show increased susceptibility to ischemia-reperfusion and over-ventilation induced injury to the lung when compared with wild type mice. Extracellular application of recombinant human MG53 (rhMG53) protein protects cultured lung epithelial cells against anoxia/reoxygenation-induced injuries. Intravenous delivery or inhalation of rhMG53 reduces symptoms in rodent models of acute lung injury and emphysema. Repetitive administration of rhMG53 improves pulmonary structure associated with chronic lung injury in mice. Our data indicate a physiological function for MG53 in the lung and suggest that targeting membrane repair may be an effective means for treatment or prevention of lung diseases. PMID:25034454

    We simulated the use of massive volumes of crystalloid fluids as a treatment of acute plasma loss in a standardized experimental model and studied the factors determining the retention or excretion of the resulting acute hypoproteinemic fluid overload, its distribution within the body, and its treatment with concentrated albumin and diuretics. In accordance with the classic Starling concept, the serum protein level, i.e. the serum colloid osmotic pressure, determined the excretion/retention ratio of a given water and sodium load. Of the total fluid retention, fat and muscle each accommodated 25%, whereas the skin, which contributes only 7% to the total body weight, accounted for 37% and increased its volume by roughly one third. Concentrated albumin promoted fluid excretion in direct proportion to the achieved increment of the serum protein level and abolished the edema of fat, muscle and skin. Furosemide was virtually ineffective. The implications of these results for the 'adult respiratory distress syndrome' and disturbed wound healing are discussed and related to the concept of a critical threshold of the serum protein level.

    Eletriptan (Relpax) is an orally administered, lipophilic, highly selective serotonin 5-HT(1B/1D) receptor agonist ('triptan') that is effective in the acute treatment of moderate to severe migraine attacks in adults. It has a rapid onset of action and demonstrates superiority over placebo as early as 30 minutes after the administration of a single 40 or 80 mg oral dose. The efficacy of eletriptan 20 mg was similar to that of sumatriptan 100 mg, while eletriptan 40 and 80 mg displayed greater efficacy than sumatriptan 50 or 100 mg for most endpoints. Eletriptan 40 mg was generally superior to naratriptan 2.5 mg and equivalent to almotriptan 12.5 mg, rizatriptan 10 mg and zolmitriptan 2.5 mg, while eletriptan 80 mg was superior to zolmitriptan 2.5 mg for most efficacy parameters. Eletriptan 40 and 80 mg were consistently superior to ergotamine/caffeine. Eletriptan is generally well tolerated, reduces time lost from normal activities, improves patients' health-related quality of life and appears to be at least as, if not more, cost effective than sumatriptan. Eletriptan is therefore a useful addition to the triptan family and a first-line treatment option in the acute management of migraine attacks. PMID:16789799

    BACKGROUND AND PURPOSE Opiates remain the most effective compounds for alleviating severe pain across a wide range of conditions. However, their use is associated with significant side effects. Neuropeptide FF (NPFF) receptors have been implicated in several opiate-induced neuroadaptive changes including the development of tolerance. In this study, we investigated the consequences of NPFF receptor blockade on acute and chronic stimulation of opioid receptors in mice by using RF9, a potent and selective antagonist of NPFF receptors that can be administered systemically. EXPERIMENTAL APPROACH The effects of RF9 were investigated on opioid pharmacological responses including locomotor activity, antinociception, opioid-induced hyperalgesia, rewarding properties and physical dependence. KEY RESULTS RF9 had no effect on morphine-induced horizontal hyperlocomotion and slightly attenuated the decrease induced in vertical activity. Furthermore, RF9 dose-dependently blocked the long-lasting hyperalgesia produced by either acute fentanyl or chronic morphine administration. RF9 also potentiated opiate early analgesic effects and prevented the development of morphine tolerance. Finally, RF9 increased morphine-induced conditioned place preference without producing any rewarding effect by itself and decreased naltrexone-precipitated withdrawal syndrome following chronic morphine treatment. CONCLUSION AND IMPLICATIONS The NPFF system is involved in the development of two major undesirable effects: tolerance and dependence, which are clinically associated with prolonged exposure to opiates. Our findings suggest that NPFF receptors are interesting therapeutic targets to improve the analgesic efficacy of opiates by limiting the development of tolerance, and for the treatment of opioid dependence.

    Acute altitude reaction is a stress response of organism to special altitude environmental factors such as hypoxia, low pressure, cold, dry and strong ultraviolet. As it is the most incident disease in high altitude areas, its prevention remains a problem to be solved. In China, the traditional Chinese (Tibetan) medicines have been recognized as an effective means of preventing and treating acute altitude sicknesses. Some single-recipe or compound traditional Chinese (Tibetan) medicines have been proved to be effective for acute altitude sicknesses. In this article, we will describe traditional Chinese (Tibetan) medicines of different types with efficacy in prevention and treatment of altitude sicknesses. PMID:24066576

    The authors have analyzed results of the roentgen computed examination of 73 patients with acute pancreatitis and its complications. The potentialities of roentgen computed tomography (RCT) in diagnosing are shown as well as computed semiotics of acute pancreatitis and its complications. The authors consider that RCT makes the diagnosis substantially more exact and enables the complications to be detected much earlier. Systematization of the signs detected by RCT in acute pancreatitis in combination with the clinical symptoms gives the information necessary for correct strategy of surgical treatment.

    The possible role of minocycline in microglial activation and neuronal death after cardiac arrest (CA) and cardiopulmonary resuscitation (CPR) in mice was investigated in this study. The mice were given potassium chloride to stop the heart beating for 8 min to achieve CA, and they were subsequently resuscitated with epinephrine and chest compressions. Forty adult C57BL/6 male mice were divided into 4 groups (n=10 each): sham-operated group, CA/CPR group, CA/CPR+minocycline group, and CA/CPR+vehicle group. Animals in the latter two groups were intraperitoneally injected with minocycline (50 mg/kg) or vehicle (normal saline) 30 min after recovery of spontaneous circulation (ROSC). Twenty-four h after CA/CPR, the brains were removed for histological evaluation of the hippocampus. Microglial activation was evaluated by detecting the expression of ionized calcium-binding adapter molecule-1 (Iba1) by immunohistochemistry. Neuronal death was analyzed by hematoxylin and eosin (H&E) staining and the levels of tumor necrosis factor-alpha (TNF-α) in the hippocampus were measured by enzyme-linked immunosorbent assay (ELISA). The results showed that the neuronal death was aggravated, most microglia were activated and TNF-α levels were enhanced in the hippocampus CA1 region of mice subjected to CA/CPR as compared with those in the sham-operated group (P<0.05). Administration with minocycline 30 min after ROSC could significantly decrease the microglial response, TNF-α levels and neuronal death (P<0.05). It was concluded that early administration with minocycline has a strong therapeutic potential for CA/CPR-induced brain injury.

  1. Evolving treatment strategies in patients with high-risk acute myeloid leukemia.

    PubMed

    2014-11-01

    Acute myeloid leukemia (AML) is defined by a set of biologically distinct diseases characterized by maturation arrest and clonal proliferation of myeloid cells. Recommendations for post-remission therapy depend on assessing the leukemia risk characteristics, such as cytogenetics and molecular features present at diagnosis. Patients with high-risk disease include those whose leukemia is characterized by monosomal karyotype or poor-risk cytogenetic or molecular abnormalities, patients with antecedent hematologic disorders or therapy-related AML, and presence of adverse host factors, such as comorbidities, impaired performance status or older age. Older patients are more likely to have these adverse features. High-risk AML responds poorly to available induction treatment and is likely to relapse despite consolidation therapy. Current data support an increasing understanding of prognosis but have not yet resulted in effective therapies for patients with high-risk disease. This review discusses current therapies and evolving treatment strategies for high-risk AML.

    This study investigates differences in terms of clinical and treatment management in psychiatric hospitalization associated to smoking ban. We collected data regarding medication, socio-demographic and admission characteristics from all patients admitted to an acute psychiatric hospital before and after a smoking ban was in force. We also assessed a limited sample of patients before and after the ban regarding nicotine dependence, motivation to quit smoking and attitudes towards the ban. More number of leaves of absence and movement restrictions during the ban period occurred in comparison to the pre-ban period. On the contrary a lack of significant differences in terms of hospital stay (duration, rate of voluntary admissions and voluntary discharges), use of sedatives and doses of antipsychotics was found. A period of adjustment regarding the deal with leave of access and facilitate nicotine replacement treatment may help future psychiatric facilities planning smoking free policies.

  3. Developments in mechanical thrombectomy devices for the treatment of acute ischemic stroke.

    2016-01-01

    Several recent prospective randomized controlled trials of endovascular stroke therapy using latest generation thrombectomy devices, so called stent-retrievers, have shown significantly improved clinical outcome compared to the standard treatment with intra-venous thrombolysis using r-tPA alone. Despite some differences in inclusion criteria between these studies, all required non-invasive vessel imaging to proof occlusion of a major brain supplying vessel. Furthermore, in most studies additional imaging techniques were used to exclude patients with already established large cerebral infarction or unfavorable collateral or penumbral status. Patients with small infarct volume, severe neurological deficits and in whom thrombectomy can be initiated within the first 6 hours after symptom onset seem to benefit the most. Therefore, mechanical thrombectomy using stent-retrievers in addition to intra-venous thrombolysis is recommended for the treatment of acute ischemic stroke with proven major vessel occlusion in the anterior circulation.

    The limited sensitivity of the historical treatment response criteria for acute myeloid leukemia (AML) has resulted in a different paradigm for treatment compared with most other cancers presenting with widely disseminated disease. Initial cytotoxic induction chemotherapy is often able to reduce tumor burden to a level sufficient to meet the current criteria for “complete” remission. Nevertheless, most AML patients ultimately die from their disease, most commonly as clinically evident relapsed AML. Despite a variety of available salvage therapy options, prognosis in patients with relapsed or refractory AML is generally poor. In this review, we outline the commonly utilized salvage cytotoxic therapy interventions and then highlight novel investigational efforts currently in clinical trials using both pathway-targeted agents and immunotherapy based approaches. We conclude that there is no current standard of care for adult relapsed or refractory AML other than offering referral to an appropriate clinical trial. PMID:25932335

    In 70 patients, suffering an acute necrotic pancreatitis (ANP), and 10 practically healthy persons a content of presepsin in a blood plasm, using immunochemiluminescent method and conducted bacteriological investigations, were analyzed. The infection occurrence is accompanied by plausible upgrading of a presepsin level in a blood plasm, depending on activity and severity of a septic process: in local infection--up to (677 ± 30) pg/ml, sepsis--up to (988 ± 47) pg/ml, severe sepsis--up to 2668 pg/ml; in an ANP without infection it have constituted (332 ± 38) pg/mI at average, in practically healthy persons--(184 ± 16) pg/mI. A presepsin level correlates with a state severity in accordance to APACHE I scale, what permits to estimate the patients state severity objectively, to prognosticate a favorable and unfavorable consequences of treatment, rapidly changing, depending on efficacy of treatment.

    Purpose: Intra-arterial therapy (IAT) is used increasingly as a treatment option for acute stroke caused by central large vessel occlusions. Despite high rates of recanalization, the clinical outcome is highly variable. The authors evaluated the Houston IAT (HIAT) and the totaled health risks in vascular events (THRIVE) score, two predicting scores designed to identify patients likely to benefit from IAT. Methods: Fifty-two patients treated at the Stavanger University Hospital with IAT from May 2009 to June 2012 were included in this study. We combined the scores in an additional analysis. We also performed an additional analysis according to high age and evaluated the scores in respect of technical efficacy. Results: Fifty-two patients were evaluated by the THRIVE score and 51 by the HIAT score. We found a strong correlation between the level of predicted risk and the actual clinical outcome (THRIVE p = 0.002, HIAT p = 0.003). The correlations were limited to patients successfully recanalized and to patients <80 years. By combining the scores additional 14.3 % of the patients could be identified as poor candidates for IAT. Both scores were insufficient to identify patients with a good clinical outcome. Conclusions: Both scores showed a strong correlation to poor clinical outcome in patients <80 years. The specificity of the scores could be enhanced by combining them. Both scores were insufficient to identify patients with a good clinical outcome and showed no association to clinical outcome in patients aged {>=}80 years.

    In a recent study we found that cerebrospinal fluids (CSFs) from amyotrophic lateral sclerosis (ALS) patients caused 20-30% loss of cell viability in primary cultures of rat embryo motor cortex neurons. We also found that the antioxidant resveratrol protected against such damaging effects and that, surprisingly, riluzole antagonized its protecting effects. Here we have extended this study to the interactions of riluzole with 3 other recognized neuroprotective agents, namely memantine, minocycline and lithium. We found: (1) by itself riluzole exerted neurotoxic effects at concentrations of 3-30 µM; this cell damage was similar to that elicited by 30 µM glutamate and a 10% dilution of ALS/CSF; (2) memantine (0.1-30 µM), minocycline (0.03-1 µM) and lithium (1-80 µg/ml) afforded 10-30% protection against ALS/CSF-elicited neurotoxicity, and (3) at 1-10 µM, riluzole antagonized the protection afforded by the 3 agents. These results strongly support the view that at the riluzole concentrations reached in the brain of patients, the neurotoxic effects of this drug could be masking the potential neuroprotective actions of new compounds being tested in clinical trials. Therefore, in the light of the present results, the inclusion of a group of patients free of riluzole treatment may be mandatory in future clinical trials performed in ALS patients with novel neuroprotective compounds.

    Objectives The physiological changes that occur during pregnancy, including increased blood volume and cardiac output, can affect hemodynamic control, most profoundly with positional changes that affect venous return to the heart. By using Osteopathic Manipulative Treatment (OMT), a body-based modality theorized to affect somatic structures related to nervous and circulatory systems, we hypothesized that OMT acutely improves both autonomic and hemodynamic control during head-up tilt and heel raise in women at 30 weeks gestation. Design One hundred subjects were recruited at 30 weeks gestation. Setting The obstetric clinics of UNTHealth in Fort Worth, Texas. Intervention Subjects were randomized into one of three treatment groups: OMT, placebo ultrasound, or time control. Ninety subjects had complete data (N=25, 31 and 34 in each group respectively). Main outcome measures Blood pressure and heart rate were recorded during 5 min of head-up tilt followed by 4 min of intermittent heel raising. Results No significant differences in blood pressure, heart rate or heart rate variability were observed between groups with tilt before or after treatment (p>0.36), and heart rate variability was not different between treatment groups (p>0.55). However, blood pressure increased significantly (p=0.02) and heart rate decreased (p<0.01) during heel raise after OMT compared to placebo or time control. Conclusions These data suggest that OMT can acutely improve hemodynamic control during engagement of the skeletal muscle pump and this was most likely due to improvement of structural restrictions to venous return.

    Passive immunization with monoclonal antibodies (MAbs) specific for the major capsular polysaccharide of Cryptococcus neoformans alters the course of murine cryptococcosis. During studies of passive immunization for treatment of murine cryptococcosis, we noted the occurrence of an acute, lethal toxicity. Toxicity was characterized by scratching, lethargy, respiratory distress, collapse, and death within 20 to 60 min after injection of antibody. The toxic effect was observed only in mice with a cryptococcal infection and was reduced or absent in the early and late stages of disease. The clinical course and histopathology were consistent with those for shock. There was considerable variation between mouse strains in susceptibility to toxicity. Swiss Webster mice from the Charles River colony were most susceptible, followed by C3H/He, BALB/c, and C57BL/6 mice. DBA/2 mice and Swiss Webster mice from the Simonsen colony were resistant. Acute toxicity was mimicked by injection of preformed complexes of MAb and purified polysaccharide. The toxic effect was also produced by injection of MAbs into mice that were preloaded with polysaccharide. The toxic effect was not blocked by treatment of mice with chloropheniramine or anti-tumor necrosis factor alpha antibodies or by depletion of complement components via pretreatment with cobra venom factor. Toxicity was reduced by treatment of mice with high doses of epinephrine, dexamethasone, or chlorpromazine. Finally, the toxic effect was completely blocked by treatment of mice with the platelet-activating factor antagonist WEB 2170 BS or by pretreatment of mice with the liposome-encapsulated drug dichloromethylene diphosphonate, a procedure which depletes macrophages from the spleen and liver.

    The aim of this prospective, multicenter, randomized, case-control study was to investigate the efficacy of a nonspecific mucosal antiseptic (octenidine dihydrochloride, phenoxyethanol) with proven antifungal effects, in patients with acute symptomatic vaginal candidosis, in comparison with a specific topical antifungal agent (clotrimazole), particularly in respect to non-Candida albicans yeasts. A total of 491 patients from 29 gynecological practices, who had new clinical vaginal mycosis, not treated with antifungal agents in the last 12 months, were included in the study. The diagnosis in each case was confirmed by microscopy or positive culture. The majority of the vaginal mycoses were infections with C. albicans (72%). In 28% of patients a non- Candida species (mainly C. glabrata) contributed to the infection. Except for vaginal discharge, the success of treatment was between 71% and 91% for both clinical and subjective parameters. The control preparation was significantly better than the treatment in the test group. Mycological cure rate on the basis of cultures was 78% in the test group and 87% in the control group. These results were also significantly different. The relatively high proportion of C. glabrata isolates in this study tended to be more successfully treated by the antiseptic (to 72%) than by the administration of clotrimazole (59%). Even though therapeutic success with clotrimazole was overall significantly better than with the test preparation, the success of treatment with the antiseptic used was within the range between 70% and 90% described for topical antifungal agents. Both the good efficacy of the topical antiseptic and the increased prevalence of non-Candida albicans species causing vaginal infections mean that the use of an antiseptic may be considered a suitable alternative therapeutic concept to an appropriate topical antifungal agent in the treatment of acute vaginal candidosis.

    AIM: To investigate the individual and combined effects of allopurinol and hyperbaric oxygen (HBO) therapy on biochemical and histopathological changes, oxidative stress, and bacterial translocation (BT) in the experimental rat acute pancreatitis (AP). METHODS: Eighty-five Sprague-Dawley rats were included in the study. Fifteen of the eighty-five rats were used as controls (sham, GroupI). AP was induced via intraductal taurocholate infusion in the remaining seventy rats. Rats that survived to induction of acute necrotizing pancreatitis were randomized into four groups. Group II received saline, Group III allopurinol, Group IV allopurinol plus HBO and Group V HBO alone. Serum amylase levels, oxidative stress parameters, BT and histopathologic scores were determined. RESULTS: Serum amylase levels were lower in Groups III, IV and V compared to Group II (974 ± 110, 384 ± 40, 851 ± 56, and 1664 ± 234 U/L, respectively, P < 0.05, for all). Combining the two treatment options revealed significantly lower median [25-75 percentiles] histopathological scores when compared to individual administrations (13 [12.5-15] in allopurinol group, 9.5 [7-11.75] in HBO group, and 6 [4.5-7.5] in combined group, P < 0.01). Oxidative stress markers were significantly better in all treatment groups compared to the controls. Bacterial translocation into the pancreas and mesenteric lymph nodes was lower in Groups III, IV and V compared to Group II (54%, 23%, 50% vs 100% for translocation to pancreas, and 62%, 46%, 58% vs 100% for translocation to mesenteric lymph nodes, respectively, P < 0.05 for all). CONCLUSION: The present study confirms the benefit of HBO and allopurinol treatment when administered separately in experimental rat AP. Combination of these treatment options appears to prevent progression of pancreatic injury parameters more effectively. PMID:18069760

    Purpose The circadian rhythm hypothesis of bipolar disorder (BD) suggests a role for melatonin in regulating mood, thus extending the interest toward the melatonergic antidepressant agomelatine as well as type I (acute) or II cases of bipolar depression. Patients and methods Twenty-eight depressed BD-II patients received open label agomelatine (25 mg/bedtime) for 6 consecutive weeks as an adjunct to treatment with lithium or valproate, followed by an optional treatment extension of 30 weeks. Measures included the Hamilton depression scale, Pittsburgh Sleep Quality Index, the Clinical Global Impression Scale–Bipolar Version, Young Mania Rating Scale, and body mass index. Results Intent to treat analysis results demonstrated that 18 of the 28 subjects (64%) showed medication response after 6 weeks (primary study endpoint), while 24 of the 28 subjects (86%) responded by 36 weeks. When examining primary mood stabilizer treatment, 12 of the 17 (70.6%) valproate and six of the 11 (54.5%) lithium patients responded by the first endpoint. At 36 weeks, 14 valproate treated (82.4%) and 10 lithium treated (90.9%) subjects responded. At 36 weeks, there was a slight yet statistically significant (P = 0.001) reduction in body mass index and Pittsburgh Sleep Quality Index scores compared to respective baseline values, regardless of mood stabilizer/outcome. Treatment related drop-out cases included four patients (14.28%) at week 6 two valproate-treated subjects with pseudo-vertigo and drug-induced hypomania, respectively, and two lithium-treated subjects with insomnia and mania, respectively. Week 36 drop outs were two hypomanic cases, one per group. Conclusion Agomelatine 25 mg/day was an effective and well-tolerated adjunct to valproate/lithium for acute depression in BD-II, suggesting the need for confirmation by future double blind, controlled clinical trials.

    A novel set up composed of an anaerobic biofilm reactor followed by ozonation was used for treatment of artificial and real textile effluents containing azo dyes. The biological treatment efficiently removed chemical oxygen demand and color. Ozonation further reduced the organic content of the effluents and was very important for the degradation of aromatic compounds, as shown by the reduction of UV absorbance. The acute toxicity toward Vibrio fischeri and the shrimp Artemia salina increased after the biological treatment. No toxicity was detected after ozonation with the exception of the synthetic effluent containing the highest concentration, 1 g/l, of the azo dye Remazol Red. Both untreated and biologically treated textile effluents were found to have mutagenic effects. The mutagenicity increased even further after 1 min of ozonation. No mutagenicity was however detected in the effluents subjected to longer exposure to ozone. The results of this study suggest that the use of ozonation as short post-treatment after a biological process can be beneficial for the degradation of recalcitrant compounds and the removal of toxicity of textile wastewater. However, monitoring of toxicity and especially mutagenicity is crucial and should always be used to assess the success of a treatment strategy.

    1992-01-01

    This retrospective study was designed to assess the effects of acyclovir treatment of acute herpes zoster on subsequent postherpetic neuralgia, and to examine the effects of amitriptyline in the treatment of postherpetic neuralgia. Eighty seven patients with postherpetic neuralgia of three or more months' duration were studied: 24 of them had had their herpes zoster treated with oral acyclovir. At first presentation, only 25% of the 24 patients who had had their herpes zoster treated with acyclovir selected the word group containing burning on the McGill pain questionnaire compared with 76% of the 63 patients who had not received acyclovir. A higher proportion of patients who had had acyclovir than had not selected the word group which contains the word aching (63% versus 49%). Acyclovir thus appears to change the nature of postherpetic neuralgia. Postherpetic neuralgia was treated with amitriptyline, alone or in combination with distigmine and/or sodium valproate. There was a strong correlation between pain relief and the interval between the occurrence of herpes zoster and the initiation of treatment with amitriptyline--early treatment is almost twice as likely to be successful as late. Since conventional analgesics and sympatholytic drugs are of no benefit in the treatment of established postherpetic neuralgia, the sequelae of herpes zoster must, therefore, be recognized and treated with amitriptyline as soon as possible.

    Alternative strategies are being designed to identify candidates among drugs already available on the market that could be used in combination to improve the efficacy of Chagas disease treatment. This work evaluates the effect of the association of clomipramine (CLO) with benznidazole (BZN) for the treatment of experimental Chagas disease in the acute stage, in Swiss albino mice infected with Trypanosoma cruzi Tulahuen strain. Infected mice were treated with CLO 5mg/kg/day and BZN 50 and 100mg/kg/day, each separately or together. Efficacy of the treatment was evaluated through parasitemia, survival, electrocardiography, histopathological studies, serological and PCR assays at 90 days post-infection (dpi). All treatments significantly (P<0.05) reduced mortality and decreased parasitemia. Histopathological analysis of liver and kidneys of mice treated with CLO and the drug combination showed less injury than mice treated only with BZN. The lower dose of BZN (50mg/kg/day) combined with CLO showed the same efficacy as the habitual dose of BZN (100mg/kg/day) combined with CLO. The therapeutic results from the combination of BZN with CLO presented lesser side effects than the treatment with BZN.

    Summary A 57-year-old female presented 17 days after treatment with radioactive iodine (RAI) for difficult-to-control hyperthyroidism. She was febrile, had a sinus tachycardia, and was clinically thyrotoxic. Her thyroid function tests showed a suppressed TSH <0.02 mU/l, with free thyroxine (FT4) >75 pmol/l and total triiodothyronine (TT3) 6.0 nmol/l. She was diagnosed with thyroid storm and was managed with i.v. fluids, propylthiouracil (PTU) 200 mg four times a day, prednisolone 30 mg once daily and propanolol 10 mg three times a day. She gradually improved over 2 weeks and was discharged home on PTU with β blockade. On clinic review 10 days later, it was noted that, although she was starting to feel better, she had grossly abnormal liver function (alanine transaminase (ALT) 852 U/l, bilirubin 46 μmol/l, alkaline phosphatase (ALP) 303 U/l, international normalized ratio (INR) 0.9, platelets 195×109/l). She was still mildly thyrotoxic (TSH <0.02 mU/l, FT4 31 pmol/l, TT3 1.3 nmol/l). She was diagnosed with acute hepatitis secondary to treatment with PTU. Ultrasound showed mild hepatic steatosis. PTU was stopped and she was managed with fluids and prednisolone 60 mg once daily and continued β blockade. Her liver function gradually improved over 10 days (bilirubin 9 μmol/l, ALT 164 U/l, ALP 195 U/l, INR 0.9, platelets 323×109/l) with conservative management and had normalised by clinic review 3 weeks later. This case highlights the potentially fatal, but rare, complications associated with both RAI and PTU, namely, thyroid storm and acute hepatitis respectively. Learning points Thyroid storm is an important, albeit rare, endocrinological emergency.Thyroid storm following RAI treatment is extremely rare.Management is with i.v. fluids, β blockade, anti-thyroid drugs and steroids.High dose glucocorticoid steroids can block the peripheral conversion of T4 to active T3.Liver dysfunction, acute hepatitis and potential hepatic failure

    Purpose: To evaluate the feasibility of endoluminal stent-grafts in the treatment of acute type B aortic dissections.Methods: In five patients with acute aortic type B dissections, sealing of the primary intimal tear with an endoluminal stent-graft was attempted. Indication for treatment was aneurysm formation in two patients and persistent pain in three patients. One of the latter also had an unstable dissection flap compromising the ostium of the superior mesenteric artery. The distance from the intimal tear to the left subclavian artery was <0.5 cm in four patients, who had typical type B dissections. In one patient with an atypical dissection the distance from the primary tear to the left subclavian artery was 4 cm. This patient had no re-entry tear. Talent tube grafts (World Medical Manufacturing Cooperation, Sunrise, FL, USA) were used in all patients.Results: Stent-graft insertion with sealing of the primary tear was successful in all patients. The proximal covered portion of the stent-graft was placed across the left subclavian artery in four patients (1x transposition of the left subclavian artery). Left arm perfusion was preserved via a subclavian steal phenomenon in the patients in whom the stent-graft covered the orifice of the left subclavian artery. The only procedural complication we observed was an asymptomatic segmental renal infarction in one patient. In the thoracic aorta thrombosis of the false aortic lumen occurred in all patients. In one patient the false lumen of the abdominal aorta thrombosed after 4 weeks; in the other three patients the status of the abdominal aorta remained unchanged compared with the situation prior to stent-graft insertion. As a late complication formation of a secondary aneurysm of the thoracic aorta was observed at the distal end of the stent-graft 3 months after the primary intervention. This aneurysm was treated by coaxial insertion of an additional stent-graft without complications.Conclusion: Endoluminal treatment

    We describe here the in vitro activities of azithromycin, clarithromycin, minocycline, or tigecycline alone and in combination with amphotericin B, itraconazole, terbinafine, voriconazole, anidulafungin, caspofungin, or micafungin against 30 isolates of the oomycete Pythium insidiosum. The assays were based on the CLSI M38-A2 technique and the checkerboard microdilution method. The main synergisms observed were through the combination of minocycline with amphotericin B (73.33%), itraconazole (70%), and micafungin (70%) and of clarithromycin with micafungin (73.33%).

    Resistance to minocycline has emerged in multidrug-resistant Acinetobacter baumannii isolates from Buenos Aires hospitals. Few reports about the description and dispersion of tet genes in this species have been published. We observed the presence of tet(B) in all minocycline-resistant isolates. This gene was found to be associated with the ISCR2 mobile element, which may, in part, explain its dispersion. PMID:23147737
