INTRODUCTION: Congenital hypofibrinogenaemia is a quantitative fibrinogen disorder characterized by proportionally decreased levels of functional and antigenic fibrinogen. Mutations accounting for quantitative fibrinogen disorders are relatively frequent in the conserved COOH-terminal globular domains of the γ and Bβ chains. The latter mutations are of particular interest since the Bβ-chain is considered the rate-limiting chain in the hepatic production of the fibrinogen hexamer. AIM: The aim of this study was to study the molecular pattern of four patients with congenital hypofibrinogenaemia...

OBJECTIVES: Liver transplant performed for hepatocellular carcinoma must adhere to criteria for the size and number of focal hepatic lesions to lower the incidence of recurrence and achieve survival rates comparable to patients transplanted for other indications. Since the Milan criteria were established in 1996, there have been many less restrictive criteria yielding similar results. Our aim was to identify the prognostic factors for patient survival and for recurrence of hepatocellular carcinoma for patients within and beyond the Milan criteria...

Hepatic space-occupying lesions refer to the lesions which are located in the abnormal echo area or density area of the liver parenchyma, have the appearance of nodule or mass, occupy a certain space, and may cause pressure, displacement, or invasion of adjacent liver tissue and vessels, as determined by imaging examination. Hepatic space-occupying lesions have various causes, as well as similarities and differences in clinical manifestations. An understanding of the etiology and clinical manifestations of hepatic space-occupying lesions helps with their diagnosis and differential diagnosis and the development of targeted therapeutic regimens to improve prognosis...

BACKGROUND: Scrub typhus, a febrile illness of substantial incidence and mortality, is caused by infection with the obligately intracellular bacterium Orientia tsutsugamushi. It is estimated that there are more than one million cases annually transmitted by the parasitic larval stage of trombiculid mites in the Asia-Pacific region. The antigenic and genetic diversity of the multiple strains of O. tsutsugamushi hinders the advancement of laboratory diagnosis, development of long-lasting vaccine-induced protection, and interpretation of clinical infection...

Aims In regenerating liver, hepatic progenitor cells (HPCs) are recruited in response to injury; however, few highly specific human HPC markers exist for the hepatocyte lineage. Leucine-rich repeat-containing G-protein coupled receptor 5 (LGR5), a Wnt-associated stem cell marker, has been extensively studied in intestinal stem cells, but little is known about its expression in human liver. We hypothesized that LGR5+ HPCs are induced in the regenerative response to pediatric liver injury. Methods and results Immunohistochemistry was used to characterize LGR5 expression in pediatric liver explants (n = 36)...

Indeterminate small (<2 cm) nodules are often discovered in cirrhotics who undergo contrast enhanced imaging for further characterization of lesions detected on ultrasound surveillance for hepatocellular carcinoma (HCC). These are either arterially enhancing (without venous washout or capsule) or are non-enhancing (with washout). Differentials include small HCCs (14-23%), atypical arterio-portal shunts, regenerative, and dysplastic nodules. A risk score that combines imaging features (arterial enhancement and nodule size) with clinical (age, prior h/o HCC) and laboratory features (albumin, AFP, hepatitis B 'e' antigen) appear to be superior to radiological features alone in the risk stratification of these nodules...

A previously healthy 70-year-old woman presented with a 5-month history of an asymptomatic keratotic, papulonodular plaque on her right forearm. The lesion started as a follicular papule followed by progressive peripheral proliferation. No record of trauma, contact with any chemicals, use of immunosuppressive drugs, or history of neoplasm was noted. Clinical examination showed an arciform plaque of 10×5 cm, with infiltrated raised borders and central atrophy (Figure 1). Drops of yellowish material exuded from the coalescent nodules constituting an elevated and indurate border...

A 62-year-old male with numerous subcutaneous nodules in the lower extremities was referred to The University of Tokyo Hospital. The patient suffered from systemic lupus erythematosus (SLE), diabetes mellitus, and persisting hepatic dysfunction, and had been treated for SLE with oral prednisolone 20 mg/day and oral cyclosporine 3 mg/kg/day. The culture of scales collected from the patient's skin surface on Sabouraud's dextrose agar medium showed features of Trichophyton rubrum. Topically applied bifonazole cream was effective for tinea corporis, but oral griseofulvin 500 mg/day was discontinued after 2-month administration because of deteriorated liver function...

Hepatocellular carcinoma (HCC) is among the most lethal and prevalent cancers in the human population. Different etiological factors such as hepatitis B and C virus, alcohol and diabetes cause liver injury followed by inflammation, necrosis and hepatocytes proliferation. Continuous cycles of this destructive-regenerative process culminates in liver cirrhosis which is characterized by regenerating nodules that progress to dysplastic nodules and ultimately HCC. Despite its significance, there is only an elemental understanding of the pathogenetic mechanisms, and there are only limited therapeutic options...

Schistosomiasis is a neglected tropical disease that can cause mainly hepatic and genitourinary damage, depending on the species. Involvement of the lungs has been commonly described in acute infection (Katayama syndrome) and chronic infection (pulmonary hypertension). Although rarely reported in the scientific literature, cases of lung nodules due to chronic schistosome infection are also possible and are probably more frequent than commonly thought. Here we report seven cases of African migrants who were diagnosed with chronic schistosomiasis and pulmonary nodules due to deposition of schistosome eggs, and we compare our findings to the case reports found in the scientific literature...
