Hodgkin disease: prediction of outcome with 67Ga scintigraphy after one cycle of chemotherapy

PURPOSE: To investigate gallium 67 scintigraphy performed early during treatment as a means to predict outcome and thus to optimize treatment of Hodgkin disease (HD) in the future. MATERIALS AND METHODS: Ninety-eight patients with HD were examined. Thirty-one patients underwent 67Ga scintigraphy after one chemotherapy cycle and 83 patients after a mean 3.5 cycles (range, 2-5 cycles). Sixteen patients underwent 67Ga scintigraphy both after one cycle and at midtreatment. Patients underwent whole-body scintigraphy and single photon emission computed tomography of the torso. Torso computed tomography (CT) was performed after a mean 3.5 cycles (range, 2-6 cycles). Failure-free survival was compared between patients with positive and patients with negative test findings (Kaplan-Meier method), and the significance of the difference was calculated. The association of failure-free survival with various prognostic clinical factors before treatment was compared (log-rank test univariate analysis). RESULTS: Failure-free survival differed significantly (P < .002) between patients with positive and patients with negative 67Ga scintigrams after one chemotherapy cycle but not at midtreatment. Failure-free survival was not significantly different between patients with positive and patients with negative CT scans at midtreatment. Twenty-two (92%) of 24 patients with negative 67Ga scintigrams after one cycle and 64 (82%) of 78 patients with negative scintigrams at midtreatment remained in complete response. In four (57%) of seven patients with positive 67Ga scintigrams after one cycle, treatment failed. CONCLUSION: 67Ga scintigraphy after one cycle of chemotherapy is a good early predictor of outcome of HD.     

Predictors of improvement in diastolic function after transcatheter aortic valve implantation

Background

Aortic stenosis is associated with concentric left ventricle (LV) hypertrophy or remodeling resulting in impaired diastolic function and elevated left-sided filling pressure. We investigated the changes in LV geometry and LV filling hemodynamics, giving emphasis to parameters associated with changes in diastolic function after transcatheter aortic valve implantation (TAVI).

Methods

Comprehensive diastolic assessment was performed before and six months after TAVI in 70 patients with severe aortic stenosis. Patients with any degree of mitral stenosis or >mild left-sided valvular regurgitation were excluded.

Results

In the entire cohort six months after TAVI, LV end-diastolic diameter increased (44.1 ± 6 versus 45 ± 6 mm, P = 0.02), whereas LV mass and relative wall thickness (RWT) decreased (270.1 ± 76 versus 245.1 ± 75 g and 0.53 ± 0.15 versus 0.46 ± 0.1, respectively; P < 0.0001 for both). Lateral e′ increased (5.8 ± 2 versus 6.6 ± 3 cm/s, P = 0.03) and left atrium (LA) volume, E/e′ ratio, and systolic pulmonary pressure decreased (88.1 ± 30 versus 80 ± 28 cc, 18 ± 7.8 versus 16.3 ± 5.5, and 42.7 ± 14.9 versus 38.7 ± 12 mmHg, respectively; P < 0.05 for all), suggesting reduction in LA pressure. The improvement in LA volume and E/e′ was almost exclusively seen in patients with LV hypertrophy before TAVI (P < 0.05 both), as opposed to patients with concentric remodeling.

Conclusions

In our preliminary study, TAVI resulted in LV and LA reverse remodeling, and improved LV relaxation and LA filling pressure in patients with severe aortic stenosis and concentric hypertrophy. Patients with concentric remodeling at baseline seem to have limited improvement in LV diastolic function and filling pressure following TAVI, but larger clinical trials would be required to conclude if they have no improvement at all.     

A miniature and mobile intermittent pneumatic compression device for the prevention of deep-vein thrombosis after joint replacement

The WizAir-DVT is a miniature, lightweight (690 g), battery-operated and mobile intermittent pneumatic compression device (ICD), which enables continuous intraoperative use and immediate patient mobilization postoperatively. We compared its efficacy with a commonly used ICD, the Kendall SCD. Peak femoral vein flow velocity was measured in 20 apparently healthy volunteers at rest and with each device: we found no significant differences between them. A second prospective, randomized, clinical trial was used to compare the efficiency of the device in preventing deep venous thrombosis (DVT) after joint replacement in 50 patients (n=25/group). None developed DVT. Doppler ultrasonography revealed no significant differences. The WizAir-DVT antithrombotic compression device is as safe and effective as the Kendall SCD.     

Incidence,Risk Factors,and Obstetrical Outcomes of Women with Breast Cancer in Pregnancy

Abstract: Breast cancer in pregnancy is a rare condition. The objective of our study was to describe the incidence, risk factors, and obstetrical outcomes of breast cancer in pregnancy. We conducted a population‐based cohort study on 8.8 million births using data from the Healthcare Cost and Utilization Project – Nationwide Inpatient Sample from 1999–2008. The incidence of breast cancer was calculated and logistic regression analysis was used to evaluate the independent effects of demographic determinants on the diagnosis of breast cancer and to estimate the adjusted effect of breast cancer on obstetrical outcomes. There were 8,826,137 births in our cohort of which 573 cases of breast cancer were identified for an overall 10‐year incidence of 6.5 cases per 100,000 births with the incidence slightly increasing over the 10‐year period. Breast cancer appeared to be more common among women >35 years of age, odds ratio (OR) = 3.36 (2.84–3.97); women with private insurance plans, OR = 1.39 (1.10–1.76); and women who delivered in an urban teaching hospital, OR = 2.10 (1.44–3.06). After adjusting for baseline characteristics, women with pregnancy‐associated breast cancer were more likely to have an induction of labor, OR = 2.25 (1.88, 2.70), but similar rates of gestational diabetes, preeclampsia, instrumental deliveries, and placental abruption. The incidence of breast cancer in pregnancy appears higher than previously reported with women over 35 being at greatest risk. Aside from an increased risk for induction of labor, women with breast cancer in pregnancy have similar obstetrical outcomes.     

Paula method of circular muscle exercises for urinary stress incontinence—a clinical trial

The aim of this study was to determine the efficacy of the Paula method of circular muscle training in the management of stress incontinence (SI). The theory behind this method states that activity of distant sphincters affects other muscles. In a pilot study, 59 women, mainly hospital employees, were randomly assigned to participate in exercises according to the Paula method or pelvic floor training. Efficacy was measured by reports of incontinence, quality of life (I-QOL), pad test, and pelvic floor muscle strength (assessed by perineometer and digital examination). Both the Paula exercises and pelvic floor training produced significant changes in urinary leakage compared to baseline as measured by the pad test [mean decrease of 5.4 g (p=0.002) and 9.5 g (p=0.003), respectively]. Women randomized to the Paula method reported improvement in I-QOL scores. The Paula method was found to be efficacious for SI in a population of Israeli women. Larger community-based studies will be required to confirm these results and enable evaluation of between-group differences.     

DOES SILDENAFIL COMBINED WITH TESTOSTERONE GEL IMPROVE ERECTILE DYSFUNCTION IN HYPOGONADAL MEN IN WHOM TESTOSTERONE SUPPLEMENT THERAPY ALONE FAILED?

PURPOSE: We evaluated the efficacy of testosterone gel (T-gel) alone and in combination with sildenafil in hypogonadal patients with erectile dysfunction (ED). MATERIALS AND METHODS: A total of 49 hypogonadal men (mean age 60.7 years) with ED participated for a mean of 20.2 months. Blood was tested for total and bioavailable testosterone, and prostate specific antigen. Sexual function was assessed using the International Index of Erectile Function questionnaire and a global assessment question (GAQ). Men received 1% 5 gm T-gel for 6 months, and 100 mg sildenafil was added to those with a "no" response to the GAQ after 3 months on testosterone supplement. RESULTS: A total of 31 patients reported significant improvement in the sexual desire domain (from a mean +/- SD of 4.2 +/- 0.8 to 8.6 +/- 0.4) and erectile function (EF) domain (from 13.6 +/- 1.9 to 27 +/- 0.8) following treatment with testosterone supplement alone. One patient was excluded from study after urinary retention developed and 9 reported irritation at the gel application site. In spite of normalization of total and bioavailable testosterone values, and significant improvement of sexual desire domain scores, the EF of 17 men remained less than 26 or they responded "no" to the GAQ. These men received combined T-gel and sildenafil, after which all graded EF greater than 26 and responded positively to the GAQ. CONCLUSIONS: Combined treatment with sildenafil and T-gel has a beneficial effect on ED in hypogonadal patients in whom treatment with testosterone supplement alone failed.     

MASSIVE GI HEMORRHAGE FROM AN ILEAL DUPLICATION CYST IN AN ADULT

We describe an unusual case of a 32-yr-old man who presented with massive GI hemorrhage as an initial manifestation of an ileal duplication cyst. The lesion was first revealed by visceral angiography during investigation of the bleeding source. At laparotomy, a large ileal duplication containing full-thickness gastric-type mucosa was identified. Ulceration of the ileal mucosa adjacent to the communicating orifice was found to be the source of bleeding. Duplications of the alimentary tract are rare congenital malformations. Patients usually present in infancy and childhood, although delayed complications can present in adulthood. This entity should be considered among other lesions that can cause massive GI hemorrhage not diagnosable by endoscopy.     

Comparative analysis of Bayer wide-range C-reactive protein (wr-CRP) and the Dade-Behring high sensitivity C-reactive protein (hs-CRP) in patients with inflammatory bowel disease

OBJECTIVE: The recently introduced Bayer wide‐range C‐reactive protein (wr‐CRP) assay might be relevant for the real‐time low‐cost and online determination of inflammatory bowel disease (IBD) activity. Our aim was to examine whether wr‐CRP can substitute for the Dade Behring high sensitivity C‐reactive protein (hs‐CRP) assay in IBD patients. METHODS: A total of 71 patients with IBD, of whom 48 had Crohn's disease CD and 23 had ulcerative colitis (UC) with various intensities of disease activity participated in the study. The CRP of patients who were under treatment at the Department of Gastroenterology and Liver Diseases were measured using both wr‐CRP and the hs‐CRP. RESULTS: A significant (r = 0.995; P < 0.001) correlation was noted between the hs‐CRP and wr‐CRP measurements for the whole sample as well as for the two diseases, CD (r = 0.994; P < 0.001) and UC (r = 0.997; P < 0.001), which were analyzed separately. CONCLUSION: The Bayer wr‐CRP assay might be a useful low‐cost and real‐time inflammation‐sensitive biomarker in patients with IBD.     

Short-term course and outcome of treatments of pleural empyema in pediatric patients: repeated ultrasound-guided needle thoracocentesis vs chest tube drainage

BACKGROUND: Several reports have suggested that early chest tube drainage (CTD) may not be necessary in the treatment of severe pleural empyema (PE) in pediatric patients if appropriate antibiotic therapy and supportive care are provided. OBJECTIVES: A prospective open study to compare the short-term course of two treatment protocols of severe PE in pediatric patients. STUDY DESIGN: One group of 32 patients was treated with early insertion of a chest tube for CTD, and a second group of 35 patients was treated by a repeated ultrasound-guided needle thoracocentesis (RUSGT). The severity of the empyema was assessed by chest radiograph, the amount of fluid drained, the number of days the patient had experienced a fever, and the duration of antibiotic treatment. RESULTS: No significant differences were found between the two groups (RUSGT vs CTD) in all of the following measurements: mean (plus minus SD) duration of a temperature > or = 39 degreesC, 6.2 +/- 2.4 vs 6.5 +/- 1.8 days, respectively; mean duration of a temperature > or = 38 degreesC, 9 +/- 3.9 vs 8.2 +/- 4.5 days, respectively; fluid drained, 35.1 + 23.8 vs 30 +/- 28.2 mL/kg, respectively; duration of antibiotic treatment, 30 +/- 13.2 vs 30.2 +/- 7.3 days, respectively; and length of hospitalization and home IV treatment, 22 +/- 7.6 vs 24.2 +/- 7.5 days, respectively. A failure to respond to treatment occurred in three patients in the RUSGT-treated group and in five patients in the CTD-treated group. The failure to respond occurred in the RUSGT-treated group only in those patients with very large empyemas that caused mediastinal deviation. CONCLUSION: The treatment of PE by RUSGT is as efficacious as CTD, unless PE causes mediastinal deviation.
