RESUMO
OBJECTIVE: The objective of this pilot project was to evaluate a model of care that consisted of a community pharmacist and registered nurse collaborating in a primary care clinic to improve guideline-directed therapy. SETTING: A regional grocery chain pharmacy partnered with a primary care clinic associated with a large academic medical center. PRACTICE INNOVATION: A community pharmacist was granted access to the electronic medical record and paired with a registered nurse care manager at a primary care office. EVALUATION: Forty-one patients were included and assessed for diabetes guidelines directed care. The pharmacist completed chart reviews and sent recommendations to a registered nurse care manager and the patient's primary care provider. The nurse facilitated lab orders, discussed the pharmacist's recommendations, and scheduled appointments as necessary for the patient. RESULTS: This intervention resulted in initial improvement in glycemic control followed by a decline at 3 months. Surrogate markers for prevention of micro- and macrovascular complications improved at 3 months. Optimization of medications for glycemic control and complication prevention also improved. CONCLUSION: The collaboration between a community pharmacist and primary care clinic led to improved adherence to guideline-directed diabetes care. Access to electronic medical records was necessary for pharmacist recommendations and communication. Pharmacist involvement in clinical recommendations at a primary care clinic in addition to standard duties at a community pharmacy may further improve care for patients with diabetes and requires further evaluation.

The majority of outer membrane (OM) lipoproteins in Gram-negative bacteria are tethered to the membrane via an attached lipid moiety and oriented facing in toward the periplasmic space; a few lipoproteins have been shown to be surface exposed. The outer membrane lipoprotein P6 from the Gram-negative pathogenic bacterium nontypeable Haemophilus influenzae (NTHi) is surface exposed and a leading vaccine candidate for prevention of NTHi infections. However, we recently found that P6 is not a transmembrane protein as previously thought (L. V. Michel, B. Kalmeta, M. McCreary, J. Snyder, P. Craig, M. E. Pichichero, Vaccine 29:1624-1627, 2011). Here we pursued studies to show that P6 has a dual orientation, existing infrequently as surface exposed and predominantly as internally oriented toward the periplasmic space. Flow cytometry using three monoclonal antibodies with specificity for P6 showed surface staining of whole NTHi cells. Confocal microscopy imaging confirmed that antibodies targeted surface-exposed P6 of intact NTHi cells and not internal P6 in membrane-compromised or dead cells. Western blots of two wild-type NTHi strains and a mutant NTHi strain that does not express P6 showed that P6 antibodies do not detect a promiscuous epitope on NTHi. Depletion of targets to nonlipidated P6 significantly decreased bactericidal activity of human serum. Protease digestion of surface-exposed P6 demonstrated that P6 is predominantly internally localized in a manner similar to its homologue Pal in Escherichia coli. We conclude that P6 of NTHi is likely inserted into the OM in two distinct orientations, with the predominant orientation facing in toward the periplasm.

P6 has been a vaccine candidate for nontypable Haemophilus influenzae (NTHi) based on its location on the outer membrane and immunogenicity. Because P6 is attached to the inner peptidoglycan layer of NTHi, and is putatively surface exposed, it must be a transmembrane protein. We examined the P6 structure using computational modeling, site-directed mutagenesis, and nuclear magnetic resonance spectroscopy. We found that P6 cannot be a transmembrane protein, and therefore may not be surface exposed. We conclude that there may be another protein on the surface of NTHi that has epitopes similar if not identical to P6.

OBJECTIVE: Autoimmune progesterone dermatitis is a rare cyclic premenstrual reaction to progesterone produced during the luteal phase of a woman's menstrual cycle with a variety of presentations including erythema multiforme, eczema, urticaria, angioedema, and progesterone-induced anaphylaxis. We present a case of progesterone-induced anaphylaxis and a review of literature focusing on its diagnosis and therapy. DATA SOURCES: We surveyed all the literature in English back to 1921 when the first case was published. First, we researched the terms progesterone anaphylaxis, autoimmune progesterone dermatitis, cyclic urticaria, using the PubMed resource. Then we included articles found within these publications' reference sections. STUDY SELECTION: We selected articles based on whether the cases described appeared to fit the description of the entity autoimmune progesterone dermatitis. All cases included had dermatologic reactions occurring during the luteal phase of the menstrual period, positive skin or intramuscular reactions to progesterone, and treatment amenable to anovulatory agents and/or hysterectomy with bilateral salpingo-oophorectomy. RESULTS: We found approximately 50 published cases of autoimmune progesterone dermatitis, and only nine known cases of its manifestation as anaphylaxis. These cases, including the case described by us, are summarized, and successful diagnostic and therapeutic approaches in the literature are reviewed. CONCLUSIONS: Autoimmune progesterone dermatitis is a rare entity associated with progesterone production of the luteal phase of a woman's menstrual cycle. It can be diagnosed using intradermal or intramuscular progesterone tests and can be treated by disrupting the ovulation cycle using specific medications or by oopherectomy.
