Incidence of inflammatory breast cancer in patients with clinical inflammatory breast symptoms

BACKGROUND

To describe a large cohort of women with non-puerperal inflammatory breast and to identify characteristics of inflammatory breast cancer.

METHODS

All patients consulting for inflammatory breast syndrome in the breast unit of our tertiary University hospital between September 2013 and December 2015 were prospectively included. We excluded women who were pregnant or in the postpartum period. Patients underwent systematic clinical examination and imaging (breast ultrasonography and mammography). A biopsy was performed if the clinician suspected a malignant lesion of the breast. Clinicopathologic and radiologic data were registered. Statistics were performed using R (3.0.2 version) software.

RESULTS

Among the 76 patients screened and included, 38 (50%) had a malignant lesion at final diagnosis, 21 (27.6%) were diagnosed with infectious disease and 17 (22.4%) with inflammatory disease of the breast. When compared to patients with benign disease, patients with a malignant lesion were significantly older (p = 0.022, CI95% 1.78-14.7), had a significantly bigger palpable mass (p<0.001, CI 95% 22.8-58.9), were more likely to have skin thickening (p = 0.05) and had more suspicious lymph nodes at clinical examination (p<0.001, CI 95% 2.72-65.3). Precise limits on ultrasonography were significantly associated with benign lesions. The presence of a mass (p = 0.04), micro calcifications (p = 0.04) or of focal asymmetry (p<0.001, CI95% 1.3-618) on mammography was significantly associated with malignant disease.

CONCLUSION

Inflammatory breast cancer was common in our cohort of women consulting for inflammatory breast syndrome. Identifying these patients with high-risk malignancy is crucial in the management of an inflammatory breast.

Progressive development of renal cysts in glycogen storage disease type I

Glycogen storage disease type I (GSDI) is a rare metabolic disease due to glucose-6 phosphatase deficiency, characterized by fasting hypoglycemia. Patients also develop chronic kidney disease whose mechanisms are poorly understood. To decipher the process, we generated mice with a kidney-specific knockout of glucose-6 phosphatase (K.G6pc^-/- mice) that exhibited the first signs of GSDI nephropathy after 6 months of G6pc deletion. We studied the natural course of renal deterioration in K.G6pc^-/- mice for 18 months and observed the progressive deterioration of renal functions characterized by early tubular dysfunction and a later destruction of the glomerular filtration barrier. After 15 months, K.G6pc^-/- mice developed tubular-glomerular fibrosis and podocyte injury, leading to the development of cysts and renal failure. On the basis of these findings, we were able to detect the development of cysts in 7 out of 32 GSDI patients, who developed advanced renal impairment. Of these 7 patients, 3 developed renal failure. In addition, no renal cysts were detected in six patients who showed early renal impairment. In conclusion, renal pathology in GSDI is characterized by progressive tubular dysfunction and the development of polycystic kidneys that probably leads to the development of irreversible renal failure in the late stages. Systematic observations of cyst development by kidney imaging should improve the evaluation of the disease's progression, independently of biochemical markers.

Case of a healthy infant born following antenatal enterovirus myocarditis and hydrops

Fetal hydrops and myocarditis were diagnosed in a woman at 32 weeks of gestation (WG). Transplacental enterovirus infection was suspected because all other causes of myocarditis and hydrops were excluded, it was during an endemic period, and there was a setting of maternal infection (fever a few days before). We opted for in utero treatment because of the risk of resuscitating a neonate with myocarditis and hydrops. We administered dexamethasone 12mg twice for pulmonary maturation and presumed it would partially improve the myocarditis. Fetal arrhythmia was noted at 35 WG and we decided to deliver the infant as postnatal treatment of the heart disorder would be more effective. RT-PCR (ARGENE(®)) showed that the neonate's throat and anal tissues and cord blood sampled on the day of birth contained enterovirus ribonucleic acid and coxsackievirus B5, as did the mother's anal sample. Laboratory tests, heart MRI and probably brain MRI indicated neonatal enterovirus infection. Findings were normal at two-year follow-up.

Indications of anti-inflammatory drugs in cardiac diseases

Throughout the history of cardiology, physicians have attempted to treat cardiac inflammatory diseases in a multitude of different ways. In recent years, three major developments have confirmed the important role of antiinflammatory drugs in cardiology: the development of new, more powerful drugs, the advent of evidence-based medicine, and the decline of rheumatic disease in western countries. Thus, we aim to review the indications for anti-inflammatory drugs in pericarditis and myocarditis. The management of pericarditis has been improved following the publication of the European guidelines in 2004. Indeed, recent randomized controlled trials highlighted the role of colchicine to i) prevent and treat recurrences of acute pericarditis and ii) prevent post pericardiectomy syndrome and its complications. With regard to the management of myocarditis, significant advances have been made towards further understanding the mechanisms involved, and in the identification of its underlying causes (especially viral vs. autoimmune). In addition, cardiac MRI and endomyocardial biopsy are now used to detect rare etiologies of myocarditis, which may benefit from immunosuppressive therapy (giant cell and eosinophilic myocarditis, cardiac sarcoidosis). Although broad consensus has yet to be reached regarding the management of acute myocarditis, identifying viral vs. autoimmune myocarditis allows a tailored treatment using antiviral or immunosuppressive drugs.

Perioperative management of hemostasis for surgery of benign hepatic adenomas in patients with glycogen storage disease type ia

The development of hepatocellular adenomas in the liver of patients with glycogen storage disease type I is a well-known complication of the disease. Surgical procedures and perioperative managements described so far have reported persistent and important morbidity. We report here a series of six patients (three males and three females) who underwent hepatic resection, and we propose a new hemostatic management protocol comprising glucose infusion, corticosteroids, desmopressin, and antifibrinolytic drugs, used to prevent efficaciously hepatic hemorrhage due to glycogen storage disease (GSD) platelet dysfunction.

Imaging of the fetal bony pelvis by computed tomography in a case of bladder exstrophy

We describe the findings on computed tomography (CT) in a prenatally diagnosed case of bladder exstrophy, and compare them with the findings on two- and three-dimensional sonography. The CT data of the affected fetus were compared with the CT findings of 14 fetuses with normal bony pelvises. The CT images showed differences in the structure of the bony pelvis in the case of bladder exstrophy, with a wide gap between the iliopubic and ischiopubic rami and a widening of the iliac bones. CT scanning was useful in confirming the sonographic diagnosis of bladder exstrophy, and it may also be helpful for planning early surgery following delivery.

Évaluation des doses d’irradiation aux organes en scanographie pédiatrique

PURPOSE

To estimate radiation doses from routine pediatric CT scans (body) and to propose dose reduction protocols.

MATERIAL AND METHODS

[corrected] Study performed with a phantom equivalent to the body of 5 year old child with evaluation of doses delivered to breast, gonads, bone marrow (sternum, T12) and thyroid for CT examinations of the chest, abdomen, pelvis and spine. Extrapolation is made to estimate the doses for 1 year old and 10 year old children. Finally, dose reduction protocols are evaluated.

RESULTS

CT of the chest delivers significant doses to breast tissue and bone marrow, CT of the abdomen and pelvis delivers significant doses to the ovaries and CT pf the spine delivers significant doses to thyroid and bone marrow. Optimization can be achieved without degradation of the image quality, by reducing Kv and mAs within reasonable limits. This study may be used in order to evaluate the doses delivered by multi-detector CT units.

Frequency and cost of serious adverse drug reactions in a department of general medicine

AIMS

To assess the frequency and cost of drug reactions causing or prolonging hospitalization.

METHODS

All patients admitted to an internal medicine ward over 6 months were evaluated to identify serious adverse reactions. The number of drug classes on admission or at the time of the adverse drug reaction (ADR) was counted. Excess ADR-related hospital stay was computed using a) raw excess duration of hospital stay, b) correction of duration of hospital stay by age, sex, and number of drug classes, and c) estimation by investigator of excess hospital stay.

RESULTS

Three hundred and twenty-nine patients were evaluated: 212 male, 117 female, mean age 57.2 (males: 52.2, females: 66.2 (P < 0.05)), range 17-95 years. They stayed a total of 3720 hospital days (mean stay 11.3 days). 298 had no ADR (mean age 55.8, taking a mean of 2.7 drug classes, 10.7 days hospital stay); 31 had ADRs: in 10, the ADR caused admission in patients with a mean age of 84 (P < 0.01 vs the two other groups), taking 6.3 drug classes, who stayed a mean of 15.1 days; 21 occurred in hospital in patients with a mean age of 63.6, taking 4.2 drug classes (P < 0.01), who stayed a mean of 19.2 days (P < 0.01 vs patients without ADRs). In four the ADR was fatal (13% of ADRs, 40% of deaths). Raw ADR-related excess hospital stay was 318 days (8.6% of all hospital days), after multivariate correction 282 days (7.6% of all hospital days), and with investigator estimation 197 days (5.3% of all hospital days). Point prevalence of ADRs at admission was 3%, incidence rate in hospital was 5.6/1000 patient-days.

CONCLUSIONS

3% of the admissions were related to ADRs. In addition, 6.6% of hospitalized patients had significant ADRs. Between 5 and 9% of hospital costs were related to ADRs. In 24 of the 31 patients with ADRs (77%), these were related to the pharmacological properties of the involved drugs, and may possibly have been avoidable.

[The question of anhaptoglobinemia in immigrants from West Africa (author's transl)]

Studying the plasmatic level and the phenotype of haptoglobine (Hp) in 71 West Africans living in France, the authors did not record any case of absence of Hp (Hpo) and did not see any significant correlation between the Hp and the duration of stay in France. They conclude that Plasmodium falciparum likely does not play any role in the origin of the Hpo peculiarity in West African immigrants.
