We report the case of a 68-year-old woman who underwent liver transplantation because of hepatitis-C-induced cirrhosis. She developed iodine-reduced hyperthyroidism postoperatively in temporal relation with cholestatic jaundice. Hepatic biopsies revealed moderate intrahepatic cholestasis and mild lobular inflammatory infiltration with some eosinophils. No histological evidence of acute graft rejection or reactivated hepatitis was found. Treatment with methimazole markedly reduced the serum parameters of cholestasis which, after subtotal thyroidectomy, returned to normal. Liver function recovered, as confirmed by repeated aminopyrine breath tests.

Antineutrophil cytoplasmic antibodies (ANCA) are frequently associated with chronic inflammatory bowel diseases (IBD) and hepatobiliary disorders. However, their target antigens have not been identified yet. Recently, we observed an atypical perinuclear ANCA fluorescence (p-ANCA) together with an intranuclear staining using ANCA-positive sera from patients with IBD and hepatobiliary disorders. This observation suggests that the target antigens are localized within the nucleus of neutrophilic granulocytes. To further investigate this hypothesis, we examined sera from patients with ulcerative colitis, primary sclerosing cholangitis, autoimmune hepatitis or systemic vasculitis on ethanol or formaldehyde-fixed neutrophils using confocal laser scanning microscopy and immunoelectron microscopy. Counterstaining with propidium iodide, a DNA-specific dye, showed that ANCA-positive sera in IBD and heptobiliary disorders react with intranuclear antigens at the nuclear periphery of the neutrophils. Double immunolabeling techniques revealed that nuclear lamina proteins, lamins A, C and B1, and lamin B receptor were colocalized with the antigen(s) recognized by atypical p-ANCA. No colocalization was observed with classical p-ANCA and antibodies against histones (H1-H4). Our study showed that atypical p-ANCA are antinuclear antibodies reactive with granulocyte-specific antigens present in the nuclear lamina.

Because HIV and hepatitis B and C infection can be transmitted by exposure to infected blood or blood components, orthopaedists are at risk for HIV and hepatitis infection during surgical procedures. Thus, care must be taken to protect themselves from transmission of HIV and the hepatitis virus. The following precautions are recommended: double latex gloves, changed hourly, or a combination of cloth and latex gloves, enclosed hood and face-masks and operative isolator with umbilical-cord aspirator; knee-length impermeable gowns of high-count polyester weave or plastic-lined nonwoven spun-lace polyester; a combination of shoe-covers that provide waterproof coverage as high as the knee; and disposable drapes. If a member of the operating team is inadvertently pricked or cut, the wound should be washed immediately with iodine, soap and water. If the injured person has been immunized for the hepatitis B (and has adequate titres), or is positive for hepatitis B surface antigen or antibody, no further treatment is necessary. Otherwise, two doses of hepatitis B immune globulin should be given, 5 mL immediately and 5 mL after 1 month. Because HIV infection can be transmitted by exposure to infected blood, orthopaedic surgeons are also at risk for HIV infection. Prospective studies suggest that this risk is very low; nevertheless, healthcare workers need to adhere rigorously to the aforementioned infection-control precautions to minimize the risk of exposure to blood.

Abnormal liver function in thyroid disorders may be secondary to thyrotoxicosis or to autoimmune injury to the liver. We report the case of a 36-year-old female who developed jaundice and pruritus with mild cholestasis and moderately elevated transaminase levels. The diagnosis of Graves' disease was made shortly thereafter. Laboratory findings were: alanine and aspartate aminotransferase 219 (IU/I (N: 9-50) and 102 IU/I (N: 10-15) respectively, alkaline phosphatase 336 IU/I (N: 40-135), bilirubin 24 micromol/I (N: 2-23), and gamma-glutamyl transpeptidase 232 IU/I (N: 9-43). Abdominal ultrasonography showed normal bile ducts; echocardiography ruled out heart failure; viral and autoimmune markers for hepatitis and cirrhosis were negative. Percutaneous liver biopsy showed moderate intrahepatic steatosis, anisokaryosis, lymphocyte infiltration in the portal areas, and Kupffer cell hyperplasia. Outcome was favorable after seven months of iodine therapy, confirming the diagnosis of thyrotoxicosis hepatitis.

Acute hepatic failure is a rare and potentially lethal complication of propylthiouracil (PTU) use for hyperthyroidism. We present a 20-year-old woman with Basedow-Graves' disease who developed PTU-induced fulminant hepatitis, which progressed to acute hepatic failure with grade III hepatic encephalopathy. Laboratory evaluation ruled out the most common causes of fulminant hepatitis. We treated her hyperthyroidism with amiodarone (average daily dose, 200 mg) for 3 weeks, achieving rapid and persistent euthyroidism, (triiodothyronine [T(3)] levels ranged between 64 and 109 ng/dL) without side effects. Amiodarone treatment did not abolish the thyroid radioactive iodine uptake (RAIU), allowing for subsequent treatment with radioactive iodine. The clinical course was favorable and the patient achieved full hepatic recovery 3 months after the hepatic failure was detected. After an extensive review of the literature, we believe that this is the first communication of the successful use of amiodarone to control hyperthyroidism in a patient with PTU-induced fulminant hepatitis.

There is an ongoing need to eradicate intercurrent disease from research mouse colonies. Commonly used surgical methods, however, are expensive and time-consuming. The purpose of this study was to determine the percentage of litters that could be rederived from infected mouse colonies by neonatal transfer. We immersed neonatal mice in a dilute iodine solution and transferred them to disease-free foster mothers within 48 h of birth. Donor and foster mothers were evaluated for pathogens by serology and fecal polymerase chain reaction (PCR) assay. Of 55 donor mothers, 100% were positive serologically and 59% were positive by fecal PCR for one or more tested organisms, including mouse hepatitis virus, Theiler's murine encephalomyelitis virus, mouse rotavirus, and Helicobacter hepaticus. At 4 to 6 weeks after neonatal transfer, 95% of foster mothers (which served as sentinels for the transferred pups) tested free of pathogens, the exceptions being one case of mouse parvovirus 1 and two of Helicobacter spp. We suggest that cross-fostering is a viable low-cost method for rederivation of mouse colonies contaminated with pathogens such as mouse hepatitis virus, Theiler's murine encephalomyelitis virus, mouse rotavirus, and H. hepaticus.

Levo-thyroxine (L-T4) is used to treat children with any form of hypothyroidism. In fact, L-T4 is the natural hormone and the principal product secreted by the thyroid. It is then converted into T3, the active compound at the tissue level, according to the temporary needs of the organism. Therefore, L-T4 can replace thyroid function in hypothyroid patients on a physiological basis. L-T4 administration is a safe and beneficial treatment that can be easily monitored by the concomitant measurement of TSH and free thyroid hormone levels. Antithyroid drugs (methimazole [MMI], carbimazole [CMI] and propylthiouracil [PTU]) are the initial treatment of choice for most children with hyperthyroidism, which is most commonly caused by Graves' disease. While generally similar in efficacy and safety, there are some differences. MMI and CMI have a longer half-life and so can be given once daily, improving compliance in children. At low doses, there are fewer side effects with MMI and CMI compared to PTU. Drug-related hepatitis and vasculitis are almost exclusively seen with PTU. Beta-adrenergic antagonists are safe adjunctive therapy. In specific situations, e.g., in preparing for thyroid surgery, iodine for a limited time is used to inhibit thyroid hormone secretion and reduce gland vascularity.

The purpose of this study was to evaluate certain clinical aspects of hyperthyroidism in Albania, which is an iodine deficient country, as it is known that iodine intake may influence the type of thyroid hyperfunction. The files of sixty-six patients with thyrotoxicosis who were hospitalised for their disease were retrospectively analysed. 59.1% of these patients suffered from toxic multinodular goiter, 27.3% from Grave's disease (toxic diffuse goiter), 10.6% from toxic adenoma, 1.5% from iodide-induced hyperthyroidism and 1.5% from transient hyperthyroidism due to subacute thyroiditis. There was an increased female to male ratio (83.3% vs 16.7%, respectively, p<0.001). 83.9% of all hyperthyroid patients lived in cities, while 16.1% lived in villages. Ophthalmopathy was found in 11.1% of patients with Graves' disease, and thyrotoxic heart disease was found in 14% of patients with thyrotoxicosis. 71.9% of all patients with hyperthyroidism were treated with propylthiouracil (PTU), while 28.1% of them were treated with methimazole; 67.2% of all these patients also received propranolol hydrochloride, while 32.8% were prescribed atenolol. Compliance was lower than that reported in other studies as only 41% of all patients received their treatment regularly. Side effects from treatment with antithyroid drugs were as follows: 4.1% (2/48) of patients treated with propylthiouracil presented leukopenia with agranulocytosis, and 6.1% of them toxic hepatitis, while 11.1% (2/18) of patients treated with methimazole presented agranulocytosis. In conclusion, the mode of presentation and side effects of hyperthyroidism appears to be different in Albania when compared with other countries, probably as a result of iodine deficiency and/or possibly nutritional status. Compliance with treatment is lower than that reported in other series, while antithyroid drug side effects seem to be more frequent. The latter observation may be due to the fact that only hospitalised patients were analysed in this study.

A 20-year-old woman given a diagnosis of hyperthyroidism (Basedow's disease) had been subsequently treated with methimazole since 1999. As she could not be made euthyroid, surgery was planned to relieve the symptoms. Because of liver dysfunction after discontinuation of methimazole and administration of iodine, she was admitted to the hospital. She was negative for hepatitis A, B and C virus serologies, but positive for anti-nuclear antibodies. A liver biopsy, which showed features of chronic active hepatitis, led to the diagnosis of autoimmune hepatitis (AIH). Interestingly, normalization of serum T4 correlated with improvement of serum aminotransferases. This leads us to speculate that this patient's liver dysfunction may have been AIH exacerbated by the liver dysfunction of hyperthyroidism rather than acute deterioration of AIH itself.
