    Notes: Summary The management of gynecologic malignancies is exceedingly complex, requiring thoughtful coordination of surgery, radiation therapy and chemotherapy. Despite the fact that the natural history and clinical course of these cancers are generally well understood, the scarring caused by surgery and/or radiation, and the marked limitations of pelvic examination make clinical staging and evaluation of limited value and known inaccuracy in following women with ovarian, cervical, uterine, vulvar and vaginal cancers. Understandably, the development of computerized axial tomography (CT), and its ability to visualize the abdomen and pelvis, lead to rapid acceptance of CT scans in defining extent of cancer and following patient response to various therapeutic interventions (Chen et al. 1980; Feigen et al. 1987; Photopoulos et al. 1977). Authors have compared the accuracy of CT findings with physical examination, surgical findings, lymphography, conventional radiography or ultrasound (Clarke-Pearson et al. 1986; Vercamb et al. 1987; Amendola 1981; Kerr-Wilson et al. 1984). However, little has been written on the effect of CT scanning on patient management. If we define and accept the accuracy of CT scanning in detecting pelvic and abdominal disease, can we show a benefit in patient management? Or, does CT scanning provide us with expensive information, or misinformation, which fails to translate into better patient care. Do complex imaging modalities compliment thorough examination and experienced clinical judgement, or only duplicate findings and provide extraneous information? To answer these questions, eighty-one months experience in using CT scanning in managing patients with gynecologic malignancies was reviewed.

    Notes: Summary Contractile and histochemical properties of the triceps surae were compared in 16 males and 4 females aged 20 to 49 years. Surface electrical stimulation was used to determine twitch, tetanic and fatigue parameters. From these tests, twitch tension (Pt), time to peak tension (TPT), half relaxation time 1/2 RT), tetanic tensions at 10, 20 and 50 Hz and an index of fatigue (FI) were calculated. A maximal voluntary contraction (MVC) was also performed. Muscle samples from the belly of the lateral gastrocnemius were obtained using the needle biopsy technique. The samples were treated histochemically for myosin ATPase and NADH-tetrazolium reductase in order to classify the fibres as either Type I, slow twitch (ST) or Type II, fast twitch (FT) and to determine fibre areas. Correlations were performed between the grouped male and female contractile and histochemical variables. The results demonstrated significant positive relationships between percentage of ST fibres (%ST) and TPT (r=0.49), and %ST and the ratio of tetanic forces at 10 Hz to 50 Hz (Po10/Po50) (r=0.55). No significant relationships were obtained for Pt, 1/2 RT, MVC or FI with any histochemical parameter. The results suggest that fibre type distribution determined using myosin ATPase is related to electrically stimulated isometric contractile speeds and not to voluntary force generation (MVC) or electrically induced fatigue.
