Two distinct and characteristic cases of osteopetrosis are presented. The first concerns a fourth month old baby with the malignant form of the disease, initiated since the newborn period. He was admitted because of abnormal ocular movements and probably deafness. At the physical examination he showed bilateral optic atrophy, abnormal ocular movements, hepatosplenomegaly and petechia. The diagnosis was confirmed by clinical means and radiological studies of virtually all of his skeleton. Several fractures were found. Laboratory tests showed marked anemia, trombocytopenia "tear cells", evidence of medullary erythropoiesis and myelofibrosis. An increased alkaline phosphatase was detected in serum and in granulocytes. The second case corresponds to a 26 year-old female with the benign form of the disease. She had multiple pathological fractures specially of her lower limbs, that produced severe impotence in her gait. In this case, the diagnosis is suspected on clinical basis and confirmed with the characteristic radiological findings. Some of the more distinct features of the disease are discussed, specially those concerning the genetic mode of inheritance and consanguinity, the etiopathogenic, pathophysiology, clinical, laboratory, prognosis and treatment, with particular reference to the radiological and hematologic problems related with this metabolic disorder.

We describe a 64-year-old man who developed cholestatic jaundice after receiving 20 to 40 mg of methyltestosterone daily for 6 months for impotence but failed to mention it as part of his drug history. He underwent endoscopic retrograde and papillotomy before a positive history for methyltestosterone ingestion could be obtained. Since methyltestosterone is most often used for sexual impotence, the patient may be quite reluctant to mention this hormone as part of his medication. A normal or mildly elevated alkaline phosphatase level, disproportionate to the level of hyperbilirubinemia seen in this patient and in all previous reports, appears to be characteristic of this phenomenon. This pattern of liver function abnormality can be a clue to suspect methyltestosterone as the causative agent and spare the patient unneeded expensive noninvasive and potentially harmful invasive procedures.

Case report on a 48-year-old Swiss male living in Burundi who suddenly fell ill with vomiting and anorexia, followed by pappy stools, weakness and impotence. He presented with hepatomegaly, while sedimentation rate and alkaline phosphatase were both elevated. Stool examination revealed cysts and vegetative forms of Entamoeba histolytica, while amebic serology was negative. Treatment with ornidazole and later with diloxanide furoate was given. Sonography showed two cystoid areas in the right lobe of the liver. In the third sonographically guided fine-needle puncture both lesions were fully aspirated. Amebic serological tests were now positive for the first time. Six weeks later the sonogram showed a normal liver feature. The symptomatology and diagnosis of hepatic amebic abscess are discussed, with special reference to the important role of sonographically guided fine-needle puncture and drainage. Sonographic technique and differential diagnosis are briefly demonstrated.

Peyronie's disease is an idiopathic disorder in which an inflammatory fibrosis occurs in the tunica albuginea of the corpora cavernosa which causes the erect penis to become deformed. Peyronie's disease has a prevalence of 1% in men over age 50 years. Paget's disease of bone is a chronic skeletal disease with areas of increased bone turnover leading to pain, deformity, and in some cases arthritis. Because of a high rate of Peyronie's disease in subjects in a Paget's disease industry-sponsored drug trial, we asked whether there was an association between Peyronie's disease and Paget's disease of bone. We evaluated 61 men with Paget's disease attending our clinic for metabolic bone disease in a tertiary referral hospital, reviewed hospital records of all men discharged from our three hospitals with the diagnosis of Peyronie's disease, and mailed a validated questionnaire about shape of the erect penis to 1500 male members of the Paget Foundation. In the clinic population of men with Paget's disease of bone, 51 of 61 (83.6%) reported having normal erections; 10 patients (16.4%) were impotent. Sixteen of the 51 men (31.4%) had developed a bend or deformity in their erect penis which was confirmed by a urologist's examination to be Peyronie's disease. When the men with Paget's disease with and without Peyronie's disease were compared, there was no difference in their ages, years with Paget's disease, or serum alkaline phosphatase level. Upon medical record review, 1 patient of 262 (0.4%) with Peyronie's disease was found to have Paget's disease of bone. The men with Paget's disease returned their questionnaires for a response rate of 44.8% and reported Peyronie's disease with a prevalence of 14.5%. We suggest that Peyronie's disease is associated with Paget's disease of bone. Furthermore, we suggest that Peyronie's disease may be a previously unrecognized complication of Paget's disease of bone.

In a bioassay-guided drug screening for anti-osteoporosis activity, eight flavonol glycosides were isolated from Epimedium koreanum Nakai, which is traditionally widely used in China for the treatment of impotence and osteoporosis. The effects of total flavonoids and flavonol glycosides on the proliferation and differentiation of rat calvarial osteoblast-like cells were evaluated by the MTT method and measuring the activity of alkaline phosphatase (ALP activity). Total flavonoids (1.2 x10(-2) to 6.0 x10(-7) mg/ml) and flavonol glycosides (2.0 x10(-5) to 1.0 x10(-9) mol/l) exhibited a strong inhibition on the proliferation of primary osteoblasts at most concentrations. However, the total flavonoids and icariin significantly promoted the differentiation of primary osteoblasts. The results suggested that flavonoids from E. koreanum Nakai may improve the development of osteoblasts by promoting the ALP activity; and icariin might be one of the active constituents facilitating the differentiation of osteoblasts.

Herba Epimedii, an herb commonly used in East Asian medicine, is commonly used for treatment of impotence, osteoporosis and many inflammatory conditions in traditional Chinese medicine. Recent studies revealed that Herba Epimedii also has anti-tumor or anti-cancer activities, which may possibly be mediated through anti-angiogenesis. This study aims to examine and confirm the anti-angiogenic activity in the herb using both in vivo and in vitro approaches. The 95% ethanol extract and four subsequent fractions (n-hexane, ethyl acetate (EA), n-butanol and aqueous fractions) of Herba Epimedii were tested on the zebrafish model by the quantitative assay for endogenous alkaline phosphatase; then, the active fraction was further tested on Tg(fli1a:EGFP)y1 zebrafish embryos and human umbilical vein endothelial cells (HUVECs) for the anti-angiogenic effects. In addition, the action mechanism of Herba Epimedii was further investigated on wild-type zebrafish embryos and HUVECs. The EA fraction showed anti-angiogenic effects in both in vivo and in vitro models. Further experiments demonstrated that it might affect angiogenesis by acting on multiple molecular targets in zebrafish embryos and ERK signaling pathway in HUVECs. In conclusion, Herba Epimedii can inhibit angiogenesis, which may be the mechanism for its anti-inflammatory, anti-tumor and anti-cancer actions.
