Digital Ischemia Associated With Cancer: Results from a Cohort Study

Digital ischemia associated with cancer (DIAC) is increasing in frequency and recent reports have suggested the concept of paraneoplastic manifestation. The aims of this study were to characterize the clinical presentation of DIAC and identify clinical features that could lead physicians to diagnose underlying cancer.From January 2004 to December 2011, 100 patients were hospitalized in the Department of Internal Medicine at Rouen University Hospital, France for a first episode of DI. Fifteen (15%) exhibited symptomatic or asymptomatic cancer during the year preceding or following vascular episode and constituted the DIAC group. Other patients without cancer made up the digital ischemia (DI) group.Median time between diagnosis of cancer and episode of digital necrosis was 2 months [0.25–9]. Diagnosis of DI and concomitant cancer was made in 7 of the 15 patients, while DI preceded the malignant disorder in 2 cases and followed it in 6 cases. Histological types were adenocarcinoma for 7 (46.7%), squamous cell carcinoma for 4 (26.7%), and lymphoid neoplasia for 3 patients (20%). Six patients (40%) had extensive cancer. Three patients were lost to follow-up and 5 patients died <1 year after diagnosis of cancer. Cancer treatment improved vascular symptoms in 6 patients (40%). Patients with DIAC, compared to patients with DI, were significantly older (56 years [33–79] vs 46 [17–83] P =0.005), and had significantly lower hemoglobin and hematocrit levels (12.7 g/dl vs 13.9 g/dl; P =0.003 and 38% vs 42%; P =0.003, respectively). Patients with DIAC had a higher platelet rate (420 vs 300 G/L P =0.01), and 6 patients with DIAC (40%) had thrombocytosis. There was no difference between groups either in C-reactive protein level (12 mg/L vs 5 mg/L; P =0.08) or regarding cardiovascular risk factors, presence of autoimmunity, or monoclonal protein.This retrospective study suggests that DIAC may be more prevalent than previously reported. Outcomes of the 2 diseases were not strictly chronologically parallel. However, in the majority of cases, treatment of the tumor resolved vascular involvement. Our findings suggest that age >50 years and thrombocytosis should alert physicians to consider a possible occult malignancy when digital necrosis occurs.     

Cumulative pregnancy rate following IVF and intracytoplasmatic sperm injection with ejaculated and testicular spermatozoa

The purpose of this study was to calculate the cumulative pregnancy rates of IVF cycles with ICSI using ejaculated or testicular spermatozoa. A computerized database for the IVF cycles with ICSI performed between January 1996 and December 1998 was utilized. Cycles with spermatozoa obtained after electro-ejaculation were excluded. A multifactorial analysis was performed to define the impact of different factors on the success rate of IVF and ICSI. During a 36-month period, 229 pregnancies were achieved by 643 couples using ejaculated spermatozoa, and 83 pregnancies by 167 couples who required testicular spermatozoa. The pregnancy rates (PR) per cycle, including all treatment cycles with ejaculated spermatozoa, remained similar during the first five consecutive cycles achieving a cumulative PR of 80.44%. The cumulative pregnancy rates for cycles with testicular spermatozoa showed a consistent rise during four consecutive treatments and reached 61.84%. The regression analysis of pregnancy rate showed that it was significantly positively correlated with oocyte fertilization rate (P = 0.02), and negatively correlated with maternal age (P = 0.03). Thus, according to the present results, couples with infertility who require IVF with ICSI should be offered at least five consecutive attempts if ejaculated spermatozoa are used, and at least four cycles whenever testicular spermatozoa are used.     

Deconstruction of p53 functions and regulation

The 11th international p53 workshop was held in Barcelona, Spain, May 15-18, 2002. The p53 workshop was organized by Carlos Cordón-Cardo (Memorial Sloan Kettering, New York). The workshop included 46 oral presentations and 206 posters.     

Primary cataract extraction and intraocular lens implantation in penetrating ocular trauma

PURPOSE: To analyze the postoperative outcome and complication rate after cataract extraction or lensectomy with primary intraocular lens (IOL) implantation for penetrating traumatic cataract. DESIGN: Retrospective, nonconsecutive, noncomparative case series. METHODS: We retrospectively reviewed the files of 21 patients who were admitted to our departments because of traumatic cataract with corneal or scleral laceration caused by penetrating trauma with or without intraocular foreign body (IOFB) from 1992 through 1997. Lens aspiration or manual extracapsular cataract extraction with primary IOL implantation was performed in all patients. Removal of an IOFB was performed in eight patients. MAIN OUTCOME MEASURES: Final visual acuity and deviation of actual refraction from emmetropia and from expected postoperative refraction. RESULTS: The mean follow-up was 20.4 months. Fourteen eyes (67%) achieved final visual acuity of 20/40 or better, 95% obtained 20/60 or better final visual acuity, and all eyes achieved 20/100 or better final visual acuity. Major causes of limited visual acuity were central corneal scar and central retinal injury. Eleven eyes (57%) experienced secondary cataract and underwent neodymium:yytrium-aluminum-garnet capsulotomy. CONCLUSIONS: Primary implantation of posterior chamber lenses after penetrating ocular trauma is associated with favorable visual outcome and a low rate of postoperative complications.     

RFID-Enabled Traceability System for Consignment and High Value Products: A Case Study in the Healthcare Sector

This paper presents a case study of a hospital operating room that evaluated a Radio-Frequency Identification (RFID)-enabled traceability system for the management of consignment and high value products requiring item level traceability. Results indicate that the traceability system in conjunction with the redesign of replenishment processes facilitates item level traceability, improves financial controls and case costing, upgrades service levels and reduces inventory shrinkage. Other benefits include time saved from non-value-added activities that can be transferred to patient care activities. The solution can be considered (i) as an alternative to RFID-enabled cabinets used in the replenishment of consignment and high value supplies in certain operating rooms, cardiac catheterization laboratories and interventional radiology departments, or (ii) as a complementary solution facilitating the tracking of medical devices removed from RFID-enabled cabinets. In short, the end-to-end traceability of medical products in the healthcare supply chain can be significantly enhanced.     

Not only headache: higher degree of sexual pain symptoms among migraine sufferers

Chronic illness and chronic pain can have profound negative effects on relationship and sexual satisfaction, yet the influence of migraine on sexuality has not been previously evaluated. To assess sexual functions in subjects with migraine compared to those with no migraine. We evaluated female university students using the Israeli sexual behavior inventory (ISBI). Migraine was diagnosed according to self-reported symptoms according to the IHS criteria. Several dimensions of female sexuality—desire, orgasm, sexual avoidance, interpersonal sexual relationship, health influence, satisfaction and pain were evaluated using a structured questionnaire. Thirty-three (23.9%) of the participants met the IHS criteria for episodic migraine with and without aura. Sexual activity, desire, orgasm and satisfaction from sexual life did not differ significantly between migraine sufferers and non-sufferers. Migraine patients reported lower ISBI scores, higher health influence on sexual life, higher levels of sexual pain and lower sexual satisfaction. Migraine negatively affected the sexual life of sufferers. Sexual pain disorder is more common among migraine sufferers compared to non-migraineurs.
