Fulminant liver failure in a patient affected by polycystic liver disease and liver metastases from breast carcinoma.

BACKGROUND: Polycystic liver disease (PLD) is a rare, congenital, benign condition characterized by the presence of multiple bile-duct-derived epithelial cysts in the liver parenchyma. The disease is usually asymptomatic, but cyst growth can result in complications such as ascites, esophageal varices, jaundice and hepatic failure. The exact mechanism leading to cyst growth is unclear, but estrogenic stimulation and paracrine action of vascular endothelial growth factor (VEGF) are thought to play a role in the growth of cyst epithelium. CASE REPORT: We report a case of acute liver failure in a young woman with PLD and liver metastases from breast carcinoma. RESULTS: No data are available in the literature about metastatic liver involvement in PLD patients affected by breast cancer. The prognosis of patients with liver metastases is generally poor but fulminant liver failure is a very rare occurrence. Estrogen stimulation seems to be a risk factor for breast cancer and severe PLD. In the reported case, the presence of either the cysts or the metastatic lesions may have resulted in more extensive liver damage. CONCLUSIONS: The adoption of drugs selected in relation to their hepatic toxicity together with careful monitoring of liver function is warranted in the management of breast cancer patients affected by PLD, in order to reduce the risk of liver failure.

Successful outcome after combined chemotherapeutic and surgical management in a case of esophageal cancer with breast and brain relapse.

Esophageal cancer (EC) is a highly lethal disease. Approximately 50% of patients present with metastatic EC and most patients with localized EC will have local recurrence or develop metastases, despite potentially curative local therapy. The most common sites of distant recurrence are represented by lung, liver and bone while brain and breast metastases are rare. Usually patients with advanced disease are not treated aggressively and their median survival is six months. We report a woman patient who developed breast and brain metastases after curative surgery. We treated her with a highly aggressive chemotherapeutic and surgical combination resulting in a complete remission of the disease even after 11-year follow-up. We think that in super selected patients with more than one metastasis, when functional status is good and metastases are technically resectable, a surgical excision may be considered as a salvage option and chemotherapy should be delivered to allow a systemic control.

Small cell lung cancer in a young patient with osteopetrosis.

BACKGROUND: Osteopetrosis or Albers-Schönberg's disease is a heterogeneous group of rare hereditary troubles of the bone characterized by bone sclerosis due to an alteration of the bone reabsorption mediated by osteoclasts. The defect in the osteoclastic activity is responsible for complete or partial medullary cavities occlusion, with consequent reduced hemopoiesis, and for the excessive fragility of the affected bone segments. CASE REPORT: We reported the case of a young man of 31 years affected by osteopetrosis in which a small cell lung cancer developed. RESULTS: Small cell lung cancer is a particularly rare neoplasm in the young, and even though it is highly sensitive to chemotherapeutic treatment its prognosis remains poor. The greatest clinical problem connected with chemotherapeutic treatment of patients affected by osteopetrosis is the variability of the reduction of their bone marrow reserve, which could expose them to an excessive hematological toxicity caused by the therapy. CONCLUSIONS: The adoption of suitable prophylactic measures, such as the use of growth factors and drugs selected in relation to their toxicity or given in reduced doses, should be appropriately considered in these subjects.

Neuropsychophysiological findings in a case of long-standing overt ventriculomegaly (LOVA).

Long-standing overt ventriculomegaly in adults (LOVA) is a clinical entity characterized by chronic hydrocephalus with infant onset, slow evolution and clinical disturbances during adulthood. Few cases are reported in literature describing the evident contrast between the severity of hydrocephalus and the relatively spared neurological functioning and cognitive aspects. The authors describe a 59-year-old man with congenital hydrocephalus complaining of persistent gait impairment. Neurological examination showed a mild paraparesis, severe higher cortical function impairment but relatively sparing of daily living activity. Computed tomography (CT) and magnetic resonance imaging (MRI) revealed a very remarkable ventriculomegaly compressing the brain cortex but sparing the cerebellum and the brainstem. Brain Single Photon Emission Computer Tomography (SPECT) showed a prevalent cerebellar perfusion as well. Neuropsychological testing was consistent with severe cognitive deterioration and attention disorders. Language and praxis functions seemed to be preserved. Auditory oddball ERPs (P300) showed morphological abnormalities especially of late components. This case report demonstrates in vivo the level of adaptation to which human brain can reach under chronic mechanic stress conditions. The striking poor cerebral parenchyma representation and the relatively spared language and praxic abilities account for a functional reorganization of residual structures due to the neural plasticity.

Phenotypic heterogeneity of latent autoimmune diabetes in adults identified by body composition analysis.

BACKGROUND: In patients with Latent Autoimmune Diabetes in Adults (LADA) a lower body mass index was reported compared with classical type 2 diabetes (T2D), and was found to be associated with a faster progression to insulin-dependence. In this study we determined the body composition in a cohort of LADA patients from Sardinia, Italy, and compared it with age- and gender-matched patients diagnosed as having adult-onset type 1 diabetes (T1D) and non-autoimmune T2D. METHODS: In 210 LADA patients, 210 T2D patients and 30 adult-onset T1D patients of Sardinian origin we assessed total and segmental body composition (weight-adjusted percent fat mass and lean mass) by using Dual Energy X-rays Absorptiometry (DXA). RESULTS: In the whole cohort of LADA patients total fat mass was significantly smaller compared with T2D patients (p < 0.0001), while no difference was found between LADA and T1D patients. In LADA men fat depletion involved all body segments, while in LADA women it was observed only in the truncal segment (p < 0.0001), as in the upper and lower regions fat deposits were larger compared to T2D (p < 0.0001). However, LADA women showed a significantly elevated truncal fat compared to T1D women (p < 0.004), whereas no difference was detected in the extremities. CONCLUSIONS: Body composition in LADA patients shows substantial difference, in a gender-dependent way, compared to classic T2D. In women fat deposits tend to accumulate in peripheral regions rather than centrally, whereas in men the distribution is more homogeneous. In addition, central fat depletion in LADA women appears to be a significant predictor of faster progression to insulin dependence. Thus, routine assessment of body composition may help the physician identify LADA patients who require early insulin treatment in order to delay beta-cell exhaustion, as well those with increased CV risk due to excess truncal adiposity.
