ZGM was purified from both primary and metastatic colonic carcinomas demonstrably positive for ZGM by immunofluorescence microscopy. ZGM purification included preparative Pevikon electrophoresis, Sepharose 4B molecular exclusion chromatography and Con A-Sepharose affinity chromatography. ZGM had an alpha2 electrophoretic mobility, an estimated molecular weight by Sepharose 4B equal to or greater than 2 x 10(6), and did not bind to Con A-Sepharose, although having determinants with CEA-like activity. Its immunologic activity was resistant to trypsin or phospholipase A but not to neuraminidase. Antisera prepared to ZGM and absorbed with saliva, when tested by double immunodiffusion, formed a single precipitation line with saline extracts of colon tumors and did not cross-react with CEA, AFP, normal tissue extracts, ferritin, NCA, NCA-2, CSAp, blood groups A, B, H, Lewis antigen, or buffy coat, alpha-2 macroglobulin, saliva or ovarian cyst fluid. Immunofluorescence microscopy confirmed the presence of ZGM in 40 out of 45 adenocarcinomas of the GI tract staining primarily in tumors, the apical cytoplasm, and in grossly nonmalignant tissues, the deep crypts of the villi, while all of 22 non-GI tumors in the study were ZGM negative.

Pigmentosis tubae (PT) is a rare condition characterized by the presence of numerous lipofuscin-laden macrophages in the lamina propria of the fallopian tube. Two women, who also had endometriotic ovarian cysts, showed polypoid pigmented tubal mucosae. In addition to lipofuscin, occasional cells showed spotty positivity for iron. Ultrastructural examination of the tubal mucosa showed the lipofuscin-containing bodies, which were similar to lipofuscin-containing lysosomes found in other pigmented conditions. Cytoplasmatic ferritin and hemosiderin in siderosomes were observed in macrophages and endothelial cells of the lamina propria. The present study is the first to demonstrate the presence of iron-containing particles and lipofuscin in the residual bodies of PT. The origin of the excess iron is not clear, but erythrophagocytosis and an abnormal tubal environment could play a role. Iron-promoted lipid peroxidation may alter the lysosomal membranes and contribute to the excessive accumulation of lipofuscin in these cells.

A 37-year-old woman with a personal history of appendicectomy, cholecystectomy, left oophorectomy secondary to an ovarian cyst complication, nephritic colic with repeated episodes of pyelonephritis, alcoholic hepatopathy, Raynaud's phenomenon and bilateral exophthalmos showed an increase in volume in the root of the upper limbs and in the base of the neck over a period of 4 years, painful to the touch and of a soft consistency. She presented with a pseudo-athletic appearance (Fig. 1) produced by an increase in the volume at the root of the upper limbs, upper back and the back of the neck (Fig. 2). The lesions produced a pulling sensation and were associated with paresthesia, hyperesthesia, and a moderate loss of strength in both arms. A biopsy taken from the upper third of the right arm showed a diffuse proliferation of the subcutaneous adipose tissue, which appeared normal, and extended between the collagen fibers, reaching in some cases into the most superficial zones of the reticular dermis (Fig. 3). Laboratory evaluation revealed a chronic anemia, leukopenia with moderate lymphopenia, increased erythrocyte sedimentation rate, elevation of enzymes of hepatic function, decrease in total proteins, and increase in ferritin, all in the context of hepatopathy. Antinuclear antibodies and the hormonal profile were normal. Abdominal and gynecologic echography revealed a right ovarian cyst of no clinical relevance. Cranial nuclear magnetic resonance (NMR) revealed an increase in the periorbital fat responsible for bilateral exophthalmos.

A systematic review is done to determine the efficacy and safety of levonorgestrel-releasing intrauterine systems as a treatment using in premenopausal women with symptomatic uterine leiomyoma. We searched the Medline, Central and ICTRP databases for all articles published from inception through July 2013 that examined the following outcomes: uterine volume, uterine leiomyoma volume, endometrial thickness, then menstrual blood loss, blood haemoglobin, ferritin and hematocrit levels, treatment failure rate, device expulsion rate, hysterectomy rate and side effects. From 645 studies, a total of 11 studies met our inclusion criteria with sample sizes ranging from 10 to 104. Evidence suggested that levonorgestrel-releasing intrauterine systems could decrease uterine volume and endometrial thickness, significantly reduce menstrual blood loss, and increase blood haemoglobin, ferritin and hematocrit levels. There was no evidence for decreasing uterine leiomyoma volume. There were no adverse effects on the ovarian function except for ovarian cysts. Device expulsion rates were low, which associated with leiomyoma size (larger than 3cm) but not with leiomyoma location. Irregular bleeding/spotting was observed at the beginning of the follow-up period and then decreased progressively. Results of this systematic review indicate that levonorgestrel-releasing intrauterine systems may be effective and safe treatment for symptomatic uterine leiomyoma in premenopausal women.
