35-38 Although these relationships have not been examined in First Nations populations, the role of acculturation and multiple AEB071 nmr traumas may play a role in these relationships. Chandler and Lalonde highlight the role of cultural continuity as a protective factor against youth suicide in First Nations.39 Residential school survivors have been found to experience adverse outcomes such as poor mental health, substance abuse, and criminal activity.25 Although First Nations individuals have higher suicide Inhibitors,research,lifescience,medical rates compared with other non-First Nations groups, these rates may vary depending on the community as well as individuals in the community. A study by

Bolton et al analyzed two American Indian samples and found that American Indians from Northern Plains and Southwest tribes were less likely to have suicidal thoughts as compared with the US general population.40 Inhibitors,research,lifescience,medical The authors also found that the Northern

Plains tribe had a greater likelihood of attempting suicide. Although some differences were found between tribes, overall American Indian samples were at greater risk for suicide attempts than the US general population. In another study examining suicidal behavior in First Nations, Mota et al investigated the correlates of suicidal Inhibitors,research,lifescience,medical behavior among a Manitoba sample of First Nations adolescents.41 The goal of this study was to examine the individual, friend/family, and community/tribe correlates of suicidal behavior among on-reserve adolescents. The authors found that several factors were found to increase Inhibitors,research,lifescience,medical the likelihood of suicidal behavior including female sex, depressed mood, abuse or fear of abuse, hospital stay, and substance use. In this study, perceived community caring played a protective role, in that adolescents were less likely to engage in suicidal behavior if they perceived their community as caring, as determined by a combination of factors regarding Inhibitors,research,lifescience,medical community life. Although further investigation is needed to understand the role of community

support and suicidal behavior in First Nations, these two studies suggest that the community may play an important role in understanding suicide, as well as the bereavement experience among some First Nations populations. The importance of culture in healing and resilience Despite the impact Gamma-secretase activity of colonization on Aboriginal peoples and collective traumas, Aboriginal cultures have endured.27 Understanding the role of healing and bereavement in Aboriginal populations necessitates the inclusion of cultural and healing traditions (Figure 1). Kirmayer investigates the symbolic aspects of healing among individuals of different cultures. Using metaphor theory, the author argues that one can understand the course of healing by examining metaphorical concepts.

Our results also confirm the previous finding that verbal materia

Our results also confirm the previous finding that verbal material that is self-generated is more

accurately remembered than material that is passively read whether it is in health or disease states (Slamecka and Graf 1978; Schefft et al. 2008b). However, in the specific case of paired associates, this self-generation effect differed depending on the linguistic relationship between the word pair. Generated words were significantly Inhibitors,research,lifescience,medical better remembered than read words in the synonym and opposite relationships, and somewhat in the category and association relationships while no recognition difference existed between read and generated words in the rhyme condition. Together, this provides support for Inhibitors,research,lifescience,medical our hypothesis that the choice of linguistic relationship has implications for memory. As discussed above, several theories were proposed to explain the memory improvement associated

with self-generation. This pattern can be attributed to the active participation that the individual is taking in achieving a task (Schefft et al. 2008b). The active learning process leads to improved Inhibitors,research,lifescience,medical mood state and self-esteem, and greater generalization of new knowledge (Schefft and Biederman 1990; Basso et al. 1994; Walsh et al. 1995). McDaniel et al. (1988) posited that self-generation improves memory because there is a heightened particularity in the items that need to be remembered. Another theory hypothesized that memory of information is enhanced when people feel self-empowered by generating that information on their own (Olofsson and Nilsson 1992;

Walsh et al. 1995). In addition, generating a word with deleted letters presents an interruption of automatic selleck chem reading Inhibitors,research,lifescience,medical processes, requiring an additional amount of conscious processing (McDaniel et al. 1989) leading to better recall. Furthermore, it has also been suggested that increased memory Inhibitors,research,lifescience,medical by way of self-generation is attributed to the depth of processing of the semantic information, rather than structural or phonological information (Craik and Tulving 1975; Craik 2002; Lespinet-Najib et al. 2004). The different effects found on recognition memory for each linguistic relationship support Cilengitide the notion that deeper semantic processing enhances memory performance (Craik and Tulving 1975; Craik 2002; Lespinet-Najib et al. 2004); and semantic and phonological relationships among words are processed by separate memory mechanisms (Martin et al. 1999), or at least require different cognitive resources (Menenti et al. 2012). Rhyming word pairs employs phonetic knowledge to self-generate a missing word according to how the words sound, while generating other types of related word pairs, such as categories, synonyms, opposites, and associations, employs semantic knowledge of what the word actually means (Craik and Tulving 1975; Martin et al. 1999; Kircher et al. 2011).

The question was posed: if the adult brain has pockets of stem ce

The question was posed: if the adult brain has pockets of stem cells that

can become neurons, astroglial cells (which play a crucial role in generating and maintaining the health of neurons), and oligodendrocytes (a third type of cell in the brain that insulates the neuronal axons so that they can transmit their information efficiently), then why can’t the brain repair itself after Inhibitors,research,lifescience,medical injury or disease? The answer seemed to be that the brain is capable of repairing itself and that it already does, to a limited extent. The current strategy is, therefore, to try to understand how, and perhaps to what end, adult neurogenesis normally occurs, in order to find ways whereby we can enhance it, direct it, and more generally harness the residual elements of neural plasticity that are inherent to neural self-repair as a treatment for brain disorders. Surprisingly, we may not be too far Inhibitors,research,lifescience,medical away from this goal. Let’s first summarize what we know about the process of adult neurogenesis. What is adult neurogenesis/cell genesis? As it turns out, the birth of new brain cells or neurogenesis Inhibitors,research,lifescience,medical is not an all-or-nothing

event. The multipotent stem cell divides periodically in the brain, giving rise to another stem cell (self-renewal) and some progeny that may grow up to be working cells, but the fate is not guaranteed. The progeny must move away from the influence of the mother stem cell into an area that is permissive for maturation. On average, about 50% of these newborn cells never make it and instead die and disappear. Those that do survive may become a neuron or glial cell, depending on where they end up and what type of activity is going on in that brain area at that time. Even so, it takes over a month from the time the new cell is born until it Inhibitors,research,lifescience,medical is functionally integrated in the brain, receiving and sending information. Thus, neurogenesis is a process, not an event, and one that – as I said earlier and will emphasize repeatedly – is highly regulated. The factors that regulate

neurogenesis are being intensely investigated and new factors that modulate different components of Inhibitors,research,lifescience,medical neurogenesis are being discovered on a GSK1363089 mw regular basis. For example, factors known to be important in development of the nervous system, like Sonic hedgehog11 (which was first discovered in fly brain and called hedgehog), this website have been shown to regulate the proliferation; BMPs (bone morphogenetic proteins) and Notch12 (which were also first discovered in fly brain) appear to be regulators of whether the newborn cells decide to become glia; and molecules associated with the glial cells that surround the stem cells instruct the newborn cells to become neurons. Once the cells are committed to becoming a neuron or glial cell, other growth factors like brain-derived neurotrophic factor (BDNF)13 and insulin-like growth factor (IGF)14play important roles in keeping the cells alive and encouraging the young cells to mature and become functional.

DEVELOPMENT OF RASAGILINE The first selective MAO-B inhibitor to be described was selegiline, which was synthesized in 1965 by Knoll and Magyar, based on methamphetamine with the addition of a propargyl group (Figure Inhibitors,research,lifescience,medical 1).25 Following administration, selegiline is extensively metabolized by hepatic cytochrome P450 2A6, 2B6, and 3A4 with the production of methamphetamine and a small percentage of other metabolites. Since selegiline is of the R(−) configuration, R(−)-methamphetamine is formed (in older nomenclature, L[−]-methamphetamine). This enantiomer of methamphetamine is often erroneously stated to be pharmacologically inactive. In fact, although S(+)-methamphetamine (previously D[+]-methamphetamine) Inhibitors,research,lifescience,medical possesses greater CNS behavioral activity, the two enantiomers have similar potency for inhibition of the plasma membrane noradrenaline transporter (NET).26 Figure 1. Structures of selegiline, rasagiline, Inhibitors,research,lifescience,medical and their metabolites.

In a large number of in vitro and in vivo pharmacological tests, selegiline was shown not to potentiate the actions of tyramine, while at the same time potentiating those of β-phenylethylamine.25 This finding was http://www.selleckchem.com/products/mek162.html interpreted by Knoll et al.25 as showing that selegiline possesses NET-inhibitory activity as well as MAO-inhibitory activity,

since inhibition of uptake inhibits Inhibitors,research,lifescience,medical the action of indirectly acting sympathomimetic amines such as tyramine. The potentiation of phenylethylamine’s effect was thought to be caused by greatly reduced metabolism of this amine. In fact, selegiline itself possesses only weak uptake-inhibitory activity.27 Selegiline was introduced into clinical medicine for treatment of Parkinson’s disease Inhibitors,research,lifescience,medical by Birkmayer and associates.28,29 Following early preclinical studies showing that it enhanced the life span of laboratory rats,30 selegiline was found to reduce death rate in human patients with Parkinson’s disease, selleck chemical but this could be due to improved clinical status of the patients rather than a true neuroprotective effect.31 Selegiline has also been found to reduce cell death in neuronal cell line types, such as PC-12 and SH-SY5Y.32,33 Following on these findings, the Parkinson’s Disease Study Group arranged a large multicenter clinical trial to determine whether selegiline, alone or in combination with alpha-tocopherol, reduces the rate of progression of the disease (DATATOP study). This trial showed that selegiline alone possesses significant symptomatic effect, but could not distinguish this from true neuroprotective effect, because the symptomatic effect of selegiline masked possible underlying disease progression.

Longitudinal data have been published in 2 cohorts of DMD patient

Longitudinal data have been published in 2 cohorts of DMD patients in Canada, Montreal and Toronto (8-12, 18). Deflazacort treatment benefitted both cohorts with prolonged ambulation, preserved cardiac and respiratory function, less scoliosis and improved survival. Common side effects reported include increased weight gain,

decreased height and cataract formation. It is unclear how deflazacort affects bone health. Delayed puberty was not commented on. There were no reported problems Inhibitors,research,lifescience,medical with wound healing, increased bacterial or viral selleck chemicals Lenalidomide infections, diabetes or glucosuria. Standards of care across Canada are quite similar. The Canadian experience supports the use of deflazacort in treating boys with DMD.
The mdx mouse has a premature stop codon mutation on exon 23 of the dystrophin gene, leading to a lack of the mature protein. The absence of dystrophin results in an acute onset of skeletal muscle necrosis around 3 weeks of post-natal life, followed by an extensive period of degeneration and regeneration until necrosis gradually decreases and a relatively Inhibitors,research,lifescience,medical low level is reached in adult mice (3-4 months)

with pathology stabilization. The pathology is far more benign than in DMD, and cardiomyopathy and fibrosis appear only in very late stage of the disease. The benign phenotype of the mdx mouse raises the Inhibitors,research,lifescience,medical main concerns about its appropriateness for pre-clinical studies; in fact drug effects can be hardly estimated while no clear consensus exists about the readout parameters that are more predictable for the human disease. In addition, a large variability exists between the experimental approaches used by various research groups and this, together with the high inter- and intra-individual variability of pathology, makes difficult Inhibitors,research,lifescience,medical Inhibitors,research,lifescience,medical to compare results obtained

in different laboratories. A detailed discussion about this topic is out of the scope of the present review. More specific reviews are available describing the effort of focused experts panels to find a consensus on the most reliable approach Brefeldin_A to enhance data predictability in mdx mouse (www.treat-nmd.eu/research/pre-clinical/SOPs [6-8]). Accordingly, standardized protocols for the assessment of various endpoints resulted from specialized working groups of experts and are available on www.treat-nmd.eu/research/pre-clinical/SOPs. Importantly to mention is the consensus raised around the protocol of forced exercise on horizontal treadmill, as the one in use in the laboratory of this review’s author, as a strategy to prolong the degenerative phase and then to enhance patient’s like alterations useful for pre-clinical evaluation of therapeutics (6, 9). This is based on the hypothesis of contractile susceptibility of dystrophic muscle, and is supported by the more severe signs in the mdx diaphragm which undergoes a continuous respiratory activity (6).

The DepoFoam particle components are naturally occurring or synt

The DepoFoam particle components are naturally occurring or synthetic analogues of common lipids, including phospholipids (e.g., dierucoylphosphatidylcholine and dipalmitoylphosphatidylglycerol), cholesterol, and triglycerides (e.g., triolein and tricaprylin). The particles typically consist of >97% water (with dissolved drug) and 1% to 3% lipids, and are expected to be fully biodegradable. The DepoFoam particles are typically suspended in isotonic solutions containing sodium chloride 0.9% Inhibitors,research,lifescience,medical in water for injection. The DepoFoam drug-delivery system is already used in

two marketed products, DepoDur and DepoCyt, which are produced by Pacira Pharmaceuticals, Inc. 2.1.2. Description of DepoFoam Bupivacaine DepoFoam bupivacaine (bupivacaine liposome injectable suspension), was supplied by Pacira Pharmaceuticals, Inc., San Diego, California, USA. Inhibitors,research,lifescience,medical This formulation was previously

designated SKY0402. The manufacture of DepoFoam particles has been previously described Inhibitors,research,lifescience,medical [12]. Briefly, the process involves a double emulsification process where the bupivacaine is added as part of the initial emulsification process. The amount of unencapsulated bupivacaine is controlled as part of the process and is generally less than 10%. In DepoFoam Bupivacaine, one of the specific lipids in the final formulation is dierucoylphosphatidylcholine, EXPAREL was initially formulated at two different dose concentrations (15 and 25mg/mL in 0.9% saline, expressed as anhydrous bupivacaine HCl equivalent). The 15-mg/mL formulation is intended for commercial use. The 15mg/mL of bupivacaine is the bupivacaine salt HCl; it Inhibitors,research,lifescience,medical is chemically equivalent to 13.3mg/mL bupivacaine free base. The 25-mg/mL formulation is a concentrated version and was intended to increase exposure of local tissues to relatively higher concentrations of both the active drug and DepoFoam Inhibitors,research,lifescience,medical matrix. 2.1.3. Reference Product Sensorcaine-MPF (methyl paraben free; bupivacaine

Animals New Zealand White rabbits and beagle dogs were ordered from Covance Gemcitabine cost Research Products, Philadelphia, Pennsylvania, and Kalamazoo, Michigan, USA, respectively. The animals were 5 and half months (rabbit) and 5 to 6 months (dog) of age on arrival. A total of 40 rabbits (20 males and 20 females) weighing 2.6 to 3.7kg and 40 dogs (20 males and 20 females) weighing 6.2 to 9.7kg, were used. Individual body weights were within 20% of the mean body weight for each gender. 2.2. Methods 2.2.1.

Kappa-values with 95% CI were analyzed within all these subgroups. Ethical Considerations Our study is a non etc interventional research and does not need to be approved by an ethics

committee under the criteria of the bioethics law. So, our study does not require the authorization of the National Commission for Informatics and Freedom due respect for patient anonymity [34]. Results During the study period, 1,949 adult patients visiting the 17 emergency departments were eligible for the study and 1,928 were included (98.9%). EDs received a mean of 113.4 Inhibitors,research,lifescience,medical adult patients ± 48.1 (median = 103, minimum = 31 and maximum = 172). Of the 1,928 patients included, 350 were excluded from the analysis because data were not available from both triage nurses and ED physicians. The final study sample comprised 1,578 patients for whom two assessments were Inhibitors,research,lifescience,medical obtained. Demographic characteristics and insurance status of ED patients

[Table ​[Table22] Table 2 Characteristics of Inhibitors,research,lifescience,medical the study population Of the 1,578 patients included in the study, 52.4% were males and the mean age of ED patients (± standard deviation (SD)) was 45.2 years ± 21.4 (from 18 to 100 years); 14.3% of patients were 75 years old and over. Most patients had primary health insurance with supplementary coverage (86.0%); 10.4% of them were covered by French health insurance specifically for individuals and families with low incomes and resources (named “CMUC”). The majority of included patients were followed by a general practitioner (92.9%). More than one third Inhibitors,research,lifescience,medical suffered from chronic disease (36.7%). Characteristics

of ED visits [Table ​[Table33] Table 3 Characteristics of the ED visits Presenting complaints had lasted less than 24 hours for 77.7% of patients. Only 17% had been referred to the ED by a primary care physician. Inhibitors,research,lifescience,medical The others were self-referred (63.4%) or referred for medico-legal reasons (19.4%) (Employer, school, police…). More than half of patients were consulting the ED for non-trauma complaints. Nearly two thirds of ED Dacomitinib patients received diagnostic tests; 59.2% received treatment in the ED, and 22.7% were hospitalized. Variability in the proportions of nonurgent ED visits and overall agreement between triage nurses and ED physicians Of the 1,578 ED visits, the proportion of nonurgent ED patients was 26% according to triage nurses upon the entry, and 34.3% according to ED physicians at the end of the consultation (p < 0.001, Table ​Table4).4). Overall level of agreement was moderate (kappa = 0.43 ± 0.02; 95% CI, 0.39% to 0.48%). The model showed a high sensitivity of 88.0% (Table ​(Table5).5). The area under the ROC curve was 0.70 with 95% CI 0.68 to 0.73 (Figure ​(Figure11).

The pharmacological inhibition of the MAPK signaling cascade in c

The pharmacological inhibition of the MAPK signaling cascade in cancer cells carrying constitutively active KRAS and BRAF mutants has been shown to improve anti-EGFR treatment with MoAbs. In this regard, it has been reported that treatment with the BRAF inhibitor, Sorafenib, can restore sensitivity to Cetuximab and Panitumumab of CRC cells carrying the V600E Inhibitors,research,lifescience,medical allele (38). So, the concomitant treatment of patients with mCRC bearing BRAF-mutated tumors, with Cetuximab/Panitumumab in combination with a BRAF inhibitor, is possible and supported by a strong rationale. MoAbs activity can be restored in BRAF mutated patients by introducing BRAF inhibitor

along with MoAbs therapy (Figure 2B). Recently

another study has reported the preclinical characterization of Vermurafenin (RG7202;PLX4032;RO5185426), which is a first-class specific small molecule BRAFV600E inhibitor in BRAF -mutated CRC cell lines Inhibitors,research,lifescience,medical and tumor xenograft models. In the Inhibitors,research,lifescience,medical same study Vermurafenin showed the dose dependent inhibition of ERK and MEK phosphorylation, which caused the inhibition of tumor growth in BRAFV600E, bearing xenograft models and arresting of cell proliferation in BRAFV600E expressing cell lines. This shows that combination of Vemurafenib with MoAbs therapy could enhance the clinical anti tumor efficacy in CRC harboring the BRAFV600E mutation (Figure 2B) (39). It has been shown that the multikinase inhibitor, Sorafenib, might restore sensitivity to EGFR inhibitors in BRAF mutated CRC cell lines, and combining of more selective BRAF inhibitors [e.g., PLX-4032 and XL-281 can also restore the sensitivity Inhibitors,research,lifescience,medical Inhibitors,research,lifescience,medical EGFR-targeted antibodies towards BRAF mutation (4)]. The first generation of RAF inhibitors, including sorafenib, were notable for their lack of specificity and potency for RAF and these agents have shown limited efficacy in tumors with a high incidence of BRAF mutation, such as, melanoma. Novel inhibitors of the pathway with Dacomitinib greater selectivity for BRAF

and MEK are now in Phase 1 and 2 clinical trials with promising early results. To maximize the likelihood of success with these agents, clinical trials enriched with patients whose tumors possess BRAF and RAS mutations have been proposed (40). It has also been reported that AZ628, a selective and potent investigational small molecule RAF kinase inhibitor, is remarkably effective at inhibiting the growth of a specific subset of human cancer cell lines derived from melanomas, thyroid cancers, and colorectal cancers that harbor the BRAF V600 mutation (41). Resistance to BRAF inhibitors Clinical responses to target anticancer therapeutics are frequently confounded by de novo or acquired resistance (42).

Bright light is one of the most powerful time cues for the intern

Bright light is one of the most powerful time cues for the internal circadlan timing system. Light exposure at specific times of the 24-h period can result in a phase-shift in the endogenous circadlan rhythms of a variety of functions, such as melatonin secretion, body temperature, and sleep propensity.34-36 These tlme-dependent effects of

light were described by phase-response curves (PRCs).13,37 In general, morning bright-light exposure induces a phase advance, whereas evening bright light exposure induces phase delay. Using the entraining properties Inhibitors,research,lifescience,medical of light to synchronize sleep-wake schedule of patients with CRSDs has become an increasingly popular therapy Artificial bright light applied by light devices at the intensities of 2000 to 4000 lux has been successfully used to realign the Orcadian phase of patients with DSPS and ASPS, and some evidence supports its effectiveness in treatment of nonentrained type sleep disorders, Inhibitors,research,lifescience,medical jet lag, shift work, and dementia.38 The American Academy of Sleep Medicine has provided the recommended intensities and time 11mits for phototherapy in the treatment of these disorders.38 Endogenous melatonin secreted by the pineal gland is another potent regulator of the sleep-wake

cycle. It is thought that the nighttime increase in melatonin concentration Inhibitors,research,lifescience,medical reduces body temperature, which promotes the onset of sleep.39 Previous findings have demonstrated that pharmacological preparations of melatonin mimic the effects of endogenous melatonin, which are time-dependent: phase advance Inhibitors,research,lifescience,medical is produced by melatonin admlnistered in the evening, whereas melatonin our administration in the morning induces phase delays.40 Thus, the PRC to melatonin is about 12 h out of phase Inhibitors,research,lifescience,medical with the PRC

to light.41 Administration of melatonin might be a preferable therapeutic strategy for many patients, who find phototherapy too demanding, leading to decreased compliance. The beneficial effects of 0.5 to 5 mg/day melatonin have been demonstrated in several types of CRSDs.42-46 Importantly, treatment with melatonin not only synchronizes the sleep-wake cycle of patients with CRSDs, but also significantly and Entinostat clinically meaningfully improves several dimensions of their daytime functioning.47 Although some recent well-designed studies indicate that even relatively large doses of melatonin (10 mg/day for a month) have no toxlcological effects,48 Its long-term effects remain to be fully researched and resolved. In patients for whom all of these treatment modalities fail to help, a rehabilitative approach is recommended. The patients should be guided to accept that their condition is permanent, and should be encouraged to consider changes in lifestyle that will be congruent with their sleep-wake cycle.

Lacouture et al described a retrospective study of 152 patients

Lacouture et al. described a retrospective study of 152 Volasertib PLK patients treated with cetuximab in which 27 cases of paronychia developed for an incidence of 17.7% (19). Forty-two culture swabs were performed and all cultures grew some organisms. Nosocomial colonization with coagulase-negative gram-positive bacteria was found in 31% and Staphylococcus aureus infection was found in 23%. Recommendations for minimizing

periungual trauma include comfortable shoes, keeping nails trimmed but Inhibitors,research,lifescience,medical avoiding aggressive manicuring, and wearing gloves for protection while cleaning and doing housework. Topical corticosteroids and anti-inflammatory doses of tetracyclines may help decrease periungual inflammation while antimicrobial soaks such as dilute bleach

in water or dilute white vinegar in water can prevent superinfection. The periungual pyogenic granuloma-like lesions clinically appear as friable vascular tissue overgrowth and Inhibitors,research,lifescience,medical commonly bleed. Local trauma may precede development of the lesions or aggravate them leading to increased symptoms of bleeding. Santiago et al. studied fourteen patients on EGFR inhibitors cetuximib or erlotinib and observed that five patients developed periungual pyogenic granulomas and four of these patients also had paronychia (20). The pyogenic granulomas Inhibitors,research,lifescience,medical occurred an average of eight weeks after beginning Inhibitors,research,lifescience,medical treatment. Medical intervention may be necessary to eliminate excessive granulation

tissue and treatment options include electrocautery, silver nitrate, and nail avulsion. Abnormalities of the hair can develop in patients taking EGFR inhibitors. Patients may experience hypertrichosis or increased hair growth. Specifically, Inhibitors,research,lifescience,medical increased hair growth of the eyebrows and eyelashes (trichomegaly) may occur (Figure 6). Patients can also develop scalp alopecia, which may be scarring or nonscarring. Figure 6 Trichomegaly during EGFR inhibitor treatment Cutaneous superinfections can complicate the cutaneous toxicities affecting patients treated with EGFR inhibitors (Figure 7). Several studies have been conducted to explore the microbiology of these infections. Amitay-Laish et al. studied 29 patients on EGFR inhibitors cetuximab or erlotinib and found that 24 patients had a papulopustular reaction (21). They divided this cohort Batimastat into two groups based on when they developed the papulopustular eruption. The early phase group contained seventeen patients and had a median onset at 8 days. The late phase group had a median onset at 200 days and contained seven patients. Staphylococcus aureus was found in 7 of 13 early phase patients and in all 7 late phase patients. The high incidence of staphylococcal infection demonstrates the importance of bacterial cultures in the assessment and treatment of EFGR inhibitor eruptions.
