Only staging is according to that of epithelial (endo- recently, the WHO has acknowledged the im- metrioid) uterine malignancies as described above. A para-aortic lymphadenectomy may be considered although this would most likely represent a staging procedure without proven survival benefit8. Postoperatively, adjuvant treatment may be recommended if there is extrauterine disease, resi- dual disease or nodal disease, but the prognosis re- mains poor. Cytotoxic agents may play a role and active agents include carboplatinum, paclitaxel and Figure 7 Carcinosarcoma filling the uterine cavity. Due to infrequent occurrence of Courtesy of Dr Judy Whittaker carcinosarcomas it is difficult to assess the true efficacy of adjuvant chemotherapy. The same goes for postoperative radiotherapy where mainly retro- spective data are available. One prospective rando- mized trial found better local control in patients receiving adjuvant pelvic radiotherapy compared to patients who did not receive radiotherapy. Radiotherapy did however not result in a better progression-free survival or overall survival. Leiomyosarcoma For leiomyosarcoma, because of its classification as a true uterine sarcoma from a histological perspec- tive a different FIGO staging classification is used (Table 6). Although leiomyosarcoma is the most common Figure 8 Heterologous carcinosarcoma of the uterus.

Some patients may present with abnormal vaginal bleeding. Preoperative investigations are similar to those for carcinosarcomas and should in- clude a full blood count, renal and liver function test. Imaging should at least include a routine chest X-ray. Ultrasound imaging which is commonly done preoperatively will not often give relevant information. The metastatic pattern of leiomyosarcoma is mainly transperitoneal and hematogenic and if there is metastatic disease it is commonly distant.

Systemic therapies with sedating antihistamines (interactions may occur) order wellbutrin 300 mg without a prescription inbreeding depression definition biology, psychopharmacy (neuroleptics discount wellbutrin 300 mg line depression storage geography definition, antidepressives), corticos- teroids and retinoids have been used. Good results have been shown with oral thalidomide up to 400 mg/day – be aware of possible neurotoxicity, teratogenicity (Matthews 1998, Maurer 2004). Occlusive bandaging can protect against mechani- cal irritations. Pruritus: Chronic, often unremitting pruritus is one of the most frequent clinical symptoms of HIV infection. In most cases, etiology remains unclear and only symptomatic treatment can be offered which may be unsat- isfying (Moses 2003, Singh 2003). Pruritus can be a complication of infectious dis- 618 Interdisciplinary Medicine eases, such as viral, bacterial, fungal infections (e. Also, dry eczematous skin (xerosis), papulosquamous skin diseases, systemic lymphomas, renal insufficiency and hepatic disease are causative conditions. Finally, many antiretrovirals and other drugs can cause pruritus (with or without rash). To diagnose idiopathic pruritus it is necessary to exclude all skin and systemic diseases mentioned above. In patients on ART it can be useful to change the treatment regimen. Systemic antihistamines and topical corticosteroids are symptomatic treatment standards. If they are ineffective, or a prolonged systemic treatment is necessary, phototherapy (UVA-1, UVB 311nm) or photochemotherapy (PUVA) is an alternative or adjuvant therapy (Smith 1997, Gelfand 2001, Zirwas 2001, Singh 2003). Concerning the immunosuppressive effects of ultraviolet light, it seems that patients on ART are at less risk. Papular dermatoses: Patients can present either with monomorphic skin colored to red papules (size 2–5 mm) or with combined eruptions consisting of papules and pustules (sterile eosinophilic pustulosis, Ofuji’s disease). According to the clinical presentation and laboratory findings (elevation of IgE, eosinophilia in peripheral blood and affected skin) they resemble the prurigo of atopic dermatitis found in adults. Autoimmune reactions against follicular antigens have also been discussed , such as eosinophilic folliculitis (Fearfield 1999). These papules can be due to a hypersensitivity reaction to drugs, microbiological agents (viruses, bacteria, fungi), parasites or saprophytes (Sarcoptes scabiei, Demodex folliculorum, Pityrosporum ovale and others). A thorough history of drugs, microbiological and histological exam- inations (including special stains such as PAS) are required for a correct diagnosis. If possible, specific infectious agents are treated. In case of sterile eosinophilic pus- tulosis (Ojufi’s disease) or papular dermatosis of unknown origin, therapy is symp- tomatic. Depending on the clinical situation, antihistamines, itraconazole (200 mg/d for 2 weeks), isotretinoin, dapsone, mild PUVA or UVB (311nm narrowband UVB is the most effective therapy) or 5% permethrin cream can be tried (Ellis 2004). Paronychia and ingrown nails: Ingrown toenails and inflammatory reactions of the proximal nailfold are a well known complication in diabetics, but also in patients on beta-blockers or retinoid therapy. A few cases might be due to local pressure (wrong shoes) or occur spontaneously. Patients on ART are the latest group of patients to regularly develop ingrown nails.
