Cancer incidence and mortality patterns in women with anorexia nervosa

Caloric restriction in animals is an effective way to reduce carcinogenesis. Anorexia nervosa (AN) is considered a model of extreme caloric restriction in humans. The aim of our study was to assess cancer incidence and mortality in women with AN. A total of 6,009 women with at least one inpatient treatment for AN during the period 1973–2003 were included in the study. Standardized incidence ratios (SIR) and standardized mortality ratios (SMR) were calculated. Overall, there was no statistically significant difference in cancer incidence compared to women in the general population. At a statistically significant or borderline significant level, a higher incidence for lung cancer and cancer of lymphoid, hematopoietic and related tissue was observed along with a reduced breast cancer incidence. Women with AN had twice as high mortality from cancer in general, and more specifically from melanoma, cancers of genital organs and cancers of ill‐defined, secondary and unspecified sites. The increased lung cancer incidence may be due to smoking habits among women with AN. The worse prognosis with higher mortality from melanoma, cancers of genital organs and cancers of ill‐defined, secondary and unspecified sites may be explained by AN‐specific attitudes toward seeking medical care, adherence to treatment or worse biological precondition due to starvation and cachexia.     

Diabetic cardiovascular autonomic neuropathy: clinical implications

Diabetic cardiovascular autonomic neuropathy (DCAN), the impairment of the autonomic balance of the cardiovascular system in the setting of diabetes mellitus (DM), is frequently observed in both Type 1 and 2 DM, has detrimental effects on the quality of life and portends increased mortality. Clinical manifestations include: resting heart rate disorders, exercise intolerance, intraoperative cardiovascular lability, orthostatic alterations in heart rate and blood pressure, QT-interval prolongation, abnormal diurnal and nocturnal blood pressure variation, silent myocardial ischemia and diabetic cardiomyopathy. Clinical tests for autonomic nervous system evaluation, heart rate variability analysis, autonomic innervation imaging techniques, microneurography and baroreflex analysis are the main diagnostic tools for DCAN detection. Aldose reductase inhibitors and antioxidants may be helpful in DCAN therapy, but a regular, more generalized and multifactorial approach should be adopted with inclusion of lifestyle modifications, strict glycemic control and treatment of concomitant traditional cardiovascular risk factors, in order to achieve the best therapeutic results. In the present review, the authors provide aspects of DCAN pathophysiology, clinical presentation, diagnosis and an algorithm regarding the evaluation and management of DCAN in DM patients.     

Skin care practices for newborns and infants: review of the clinical evidence for best practices

In recent years, there have been continuing efforts to understand the effects of baby skin care routines and products on the healthy development of baby skin. Such efforts aim ultimately to determine the best infant skin care practices. The pediatric and dermatologic communities have not reached consensus on what constitutes an appropriate cleansing practice. In the United States, guidelines for neonatal skin care have been developed, propagated, and implemented. The accumulated knowledge has promoted evidence-based clinical practices and, therefore, may help to improve clinical outcomes, although these guidelines primarily cover the care of preterm newborns and the treatment of those with other health problems. High-level, long-term clinical evidence of the effective and safe cleansing of healthy, full-term newborns and infants is scarce. This review presents a comprehensive analysis of the scientific literature on baby skin development, cleansing practices, and related products (for healthy newborns and babies) since 1970. The evidence drawn from the reviewed literature can be summarized as follows: Bathing immersed in water seems generally superior to washing alone. Bathing or washing with synthetic detergents (syndets) or mild liquid baby cleansers seems comparable with or even superior to water alone. Nevertheless, larger randomized clinical trials with age-defined cohorts of babies as well as more-defined parameters are required to identify optimal practices and products for skin cleansing of healthy infants. These parameters may include standardized skin function parameters such as transepidermal water loss, stratum corneum hydration, skin surface pH, and sebum production. Clinical skin scores such as the Neonatal Skin Condition Score may be employed as outcome measures.     

Common variable immunodeficiency complicated with hemolytic uremic syndrome

Common variable immunodeficiency is a primary immunodeficiency disease characterized by reduced serum immunoglobulins and heterogeneous clinical features. Recurrent pyogenic infections of upper and lower respiratory tracts are the main clinical manifestations of common variable immunodeficiency. Hemolytic uremic syndrome is a multisystemic disorder characterized by thrombocytopenia, microangiopathic hemolytic anemia, and organ ischemia due to platelet aggregation in the arterial microvasculature. This is one of the rare cases of patients diagnosed with common variable immunodeficiency, which was complicated by hemolytic uremic syndrome.     

Bilirubin levels predict renal cortical changes in jaundiced neonates with urinary tract infection

Background  This study was undertaken to determine the incidence of urinary tract infection (UTI) and the frequency of anatomical abnormalities in newborns with unexplained jaundice and to find out if there is any correlation between bilirubin level and renal damage. Methods  We studied 462 full-term neonates for UTI. They were aged 3–25 days, with either high (>10 mg/dL) or prolonged (>10 days) hyperbilirubinemia, with or without manifestations such as fever, vomiting, diarrhea, poor feeding, lethargy, and irritability. Neonates positive for UTI were further investigated with ultrasound, cystourethrography, and acute phase renal scintigraphy with technetium-99m dimercaptosuccinate acid (DMSA). Results  Thirty neonates (6.5%) were found to have UTI. Twenty-eight of them had indirect hyperbilirubinemia and two had direct hyperbilirubinemia, with total bilirubin levels of 11.8–20.1 mg/dL. None of the neonates was found to have jaundice because of other reasons such as infection. Vesicoureteral reflux was found in 5 neonates and one of them was combined with hydronephrosis. Renal scintigraphy with technetium-99m DMSA showed renal cortex changes in 14 (46.7%) of the 30 neonates with UTI. These 14 neonates also had increased levels of bilirubin in comparison to those with normal findings of DMSA. Conclusions  The incidence of UTI in uncomplicated neonatal jaundice is relatively high. Anatomical abnormalities of the urinary tract are not rare in infected children. Increased bilirubin levels are related to pathological findings in renal scintigraphy.     

Combination pharmacotherapy in the treatment of experimental cardiac arrest

Study Objectives

Full recovery after cardiopulmonary resuscitation (CPR) is poor. We hypothesized that the coadministration of epinephrine, a β-blocker such as atenolol, and a calcium sensitizer such as levosimendan during CPR would improve survival and postresuscitation myocardial function.

Methods

Ventricular fibrillation was induced in 60 piglets, which were left untreated for 8 minutes before attempted resuscitation. Animals were randomized into 4 groups (n = 15), to receive epinephrine (group E), epinephrine + atenolol (group E + A), epinephrine + levosimendan (group E + L) and epinephrine + atenolol + levosimendan (group E + A + L) during CPR. Electrical defibrillation was attempted 2 minutes after drug administration.

Results

Five animals in group E survived for 48 hours in comparison to 8 animals in groups E + A and E + L and 12 animals in group E + A + L. Postresuscitation cardiac output was significantly better in the animals of group E + A + L. Troponin I remained significantly lower in groups E + A and E + A + L. Serum astroglial protein (S-100) and neuron-specific enolase values in group E + L and E + A + L were statistically lower than those measured in groups E and E + A during the entire observation period. The neurologic alertness score was higher in group E + A + L compared to groups E and E + A.

Conclusions

The administration of a drug combination of epinephrine + atenolol + levosimendan, when given during CPR, in a pig model of cardiac arrest, results in improved 48-hour survival and improves postresuscitation cardiac function.     

Selective hepatic arterial infusion of In-111-DTPA-Phe<Superscript>1</Superscript>-octreotide in neuroendocrine liver metastases

Purpose  The aim of this study is to evaluate the effectiveness of ¹¹¹In-DTPA-Phe¹-octreotide infusions after selective catheterization of the hepatic artery in inoperable metastasised liver, sst₂ receptor-positive neuroendocrine tumours due to the effect of ¹¹¹In Auger electron emission, minimising in parallel the toxicity of non-target tissue. Methods  The average dose per session administered monthly to each patient (17 cases in total) was 6.3 ± 2.3 GBq. Repetitions did not exceed 12-fold, except in one case (15 sessions). Response assessment was classified according to the Response Evaluating Criteria in Solid Tumours. CT/MRI scans were performed as baseline before, during and after the end of treatment, and monthly ultrasound images for follow-up measurements. Toxicity (World Health Organization criteria) was measured using blood and urine tests of renal, hepatic and bone marrow function. Results  Complete response was achieved in one (5.9%) patient and partial in eight (47.0%), and disease stabilization in 3 (17.7%) patients; five (29.4%) did not respond. A 32-month median survival time was estimated in 12 (70.5%). Nine of these 12 surviving had a mean target diameter shrinkage from 144 ± 81 to 60 ± 59 mm. Grade 1 erythro-, leuko- and thrombo-cytopenia occurred in three (17.6%) cases. Conclusion  In unresectable metastatic liver lesions positive for somatostatin receptors repeated, transhepatic high doses of ¹¹¹In-DTPA-Phe¹-octreotide show an effective therapeutic outcome. Given the locoregional modality character of the administration technique plus the extremely short range of ¹¹¹In Auger and internal conversion electrons emission, no nephro-, liver- or myelo-toxicity has so far been observed.     

An emergency diagnostic dilemma: a case of <Emphasis Type="Italic">Yersinia enterocolitica</Emphasis> colitis mimicking acute appendicitis in a β-thalassemia major patient: the role of CT and literature review

The role of computed tomography (CT) scanning in a case of Yersinia enterocolitica (YE) enteritis mimicking acute appendicitis in a 34-year-old female patient with β-thalassemia major is presented. Although the abdominal CT findings on admittance were indicative of acute appendicitis (enlargement of the appendix and thickening of its wall), making appendectomy a likely treatment option, a second CT scan 3 days later was diagnostic for infectious colitis (bowel wall thickening, ulcerations of the colonic mucosa, and fat stranding), and an unnecessary appendectomy was thus avoided. The diagnosis of YE colitis was later confirmed by serology tests.
