Surgical therapy is the only useful correction in congenital fibrosis or in hypoplasia of the 'corpora cavernosa', associated with hypospadia or not. On the contrary in not congenital fibrosis of the 'corpora cavernosa' (Peyronie's disease, consequences of priapism, or trauma, complications of pharmaco-prosthesis) are allowed pharmaco-physical treatments (infiltrations, ionophoresis, ultrasound, laser). Pharmaco-physical therapy can be used as the only treatment, which is often resolutive, but it is also useful before or after the surgical operation of the 'corpora cavernosa'. These diseases can give disorders of the erection, until complete impotence is reached. In fact the erectile tissue can't expand, because of the rising fibrosclerosis. Among acquired fibrosis of corpora cavernosa I.P.P. has surely the greatest recurrent: the consistency of our series made possible to achieve significant results with a unified therapeutical protocol. The same management was applied in other, less frequent, penile fibrosis, always with full positive results even if on a small number of patients. We are evaluating a new drug (defibrotide) in the treatment of cavernosal vasculitis. Another one (hyaluronidase) associated to orgotein, could improve its effect against inflammation especially in chronic evolutions. Besides new treatments, we emphasize the prevention of iatrogenic fibrosis with particular regard to cavernous pharmaco-infusions by autoinjections: the training of the patient and the safety of the autoinjectors must be carefully checked by the andrologist to decrease a large amount of complications.

The presence and localization of fibrin and fibronectin in rheumatoid nodules were studied using an indirect immunoperoxidase technique on tissue specimens fixed in formaldehyde, embedded in paraffin and pretreated with pepsin and testicular hyaluronidase. Three zones characteristic for rheumatoid nodules was recognized. Central area with necrosis, containing at least in part fibrinogen-antigenic material and fibronectin especially in the peripheral part of the necrotic area. Around the necrosis a layer of mesenchymal cells in a palisade arrangement was found. Especially in the external part of this layer fibronectin was demonstrated around and between the cells, where fibrin was absent. Peripherally, a zone of non-specific granulation tissue containing moderate amount of fibronectin decreasing towards the surround mature connective tissue, was seen. In the border of the cellular layer vessels were found in variable amount. In some of the vessels vasculitis was demonstrated with the presence of inflammatory cell infiltration, fibrin deposition and occasionally thrombosis. The pathogenesis of the inflammatory reaction in rheumatoid nodules is discussed.

Tuberculous meningitis is primarily a disease of the meninges of brain and spinal cord along with adjacent brain parenchyma. The characteristic pathological changes are meningeal inflammation, basal exudates, vasculitis and hydrocephalus. Tuberculous meningitis has a strong predilection for basal parts of the brain. Exudates, if dominantly present in the interpeduncular, suprasellar and Sylvian cisterns, result in optochiasmatic arachnoiditis and tuberculoma. Optochiasmatic arachnoiditis and tuberculoma are devastating forms of tuberculous meningitis and often associated with profound vision loss. This clinical entity more frequently affects young adults. In a recent study, on the multivariate logistic regression analysis, female sex, younger age and raised cerebrospinal fluid protein content were identified as predictors for developing optochiasmatic arachnoiditis. Frequently, optochiasmatic tuberculoma and optochiasmatic arachnoiditis develop paradoxically while a patient is being treated with anti-TB drugs. MRI reveals confluent enhancing lesions that are present in the interpeduncular fossa, pontine cistern, and the perimesencephalic and suprasellar cisterns. Management of tuberculous optochiasmatic arachnoiditis and optochiasmatic arachnoiditis tuberculoma has been variable. Treatment of optochiasmatic arachnoiditis continues to be a challenge and the response is generally unsatisfactory. In isolated case reports and in small series, corticosteroids, methyl prednisolone, thalidomide and hyaluronidase have been used with variable success. The benefit from neurosurgery is controversial and deterioration may follow the initial temporary improvement. Management of paradoxical optochiasmatic arachnoiditis is also controversial. Some patients regain vision following treatment with anti-TB drugs and continued usage of corticosteroids. Neurosurgery may be considered in the patients with either treatment failure or when diagnosis is in doubt. In conclusion, presence of optochiasmatic arachnoiditis or tuberculoma has important therapeutic and prognostic implications for patients of tuberculous meningitis.
