Use of high voltage pulsed galvanic stimulation for patients with levator ani syndrome.

Levator ani syndrome is characterized by brief, intermittent pain and discomfort in the perirectal or rectal region that can be aggravated by sitting. Physical therapists are beginning to receive referrals for pain reduction in this patient population. The purpose of the study was to examine the use of high voltage pulsed galvanic stimulation (HVPGS) for reducing symptoms in patients with levator ani syndrome. A descriptive research design was used. Treatment consisted of one hour of HVPGS at a frequency of 120 Hz and at an intensity to the patient's maximum tolerance applied through a rectal probe. Results on 28 patients indicate that 50% had pain or symptom relief, or both, after an average of eight treatments. Those patients who were unresponsive to treatment had a primary diagnosis of irritable colon or were postsurgical. We are continuing to examine this treatment and will conduct follow-up examinations on those patients who obtained pain relief. Based on these preliminary results, we believe that HVPGS is an effective treatment for selected patients in this population.

Lymphocyte subpopulations and function in cystic fibrosis.

Circulating lymphocytes subpopulations and their function have been studied in 25 young adults with cystic fibrosis (CF) and 25 normal controls. Mean absolute numbers of all lymphocyte subsets in the CF group were not significantly different from the controls. Antibody-dependent cell cytotoxicity was significantly higher in the CF patients who had Pseudomonas aeruginosa in their sputum compared with those who had not and compared with the normal controls. Within the CF group the numbers of B cells, total T cells and OKT4+ helper cells fell as percent predicted peak expiratory flow (PEF) declined and similar significant positive correlations were found between lymphocyte subsets and percent predicted body weight. Serum albumin levels also showed a positive correlation with total T lymphocyte numbers (p less than 0.05). In vitro lymphocyte proliferative responses to mitogen were not significantly different from the control group, but again correlated positively with body weight in the CF patients. This provides further evidence that immune function in CF patients may become impaired as pulmonary disease and nutritional status deteriorate.

Localization and function of tissue macrophages.

The rat monoclonal antibody F4/80 defines a plasma membrane glycoprotein of about 160 kilodaltons that is expressed by mature mouse macrophages. The antigen has been used to define macrophage distribution within the mouse (normal adult, embryo, infection models) by cytochemistry and quantitative immunochemical analysis. Macrophages migrate into fetal and adult haemopoietic and other tissues in an ordered sequence. The surface properties of 'fixed' macrophages isolated from various organs (bone marrow, liver, spleen) are distinct from those of circulating monocytes or free cells (peritoneal and pleural cavities, alveolar) and may play a role in local adhesion and trophic interactions with other cells.

Focal fatty liver lesions in alcoholic liver disease: a broadened spectrum of CT appearances.

The CT examinations of 26 consecutive alcoholic patients with focal fatty infiltration of the liver were analyzed. Five different patterns of focal fatty infiltration were noted. In most alcoholic patients these appearances present no diagnostic problem and further confirmation can be obtained by repeating the CT scan within 1-2 weeks to see if interval resolution occurs following enforced abstinence. In select instances, more invasive and definitive procedures such as superselective angiography or liver biopsy may be necessary to differentiate these findings from other more serious diseases they may closely resemble, such as primary or secondary liver neoplasms.

Sterilization in the northeast of Brazil.

Results of household surveys carried out in four states in the Northeast of Brazil showed that female sterilization is the most prevalent method among women who want no more children. Many women who indicated an interest in tubal ligation, however, had not been sterilized. Access to sterilization depends on the type of hospital in which the child was delivered and the type of delivery the woman had. Over 60% of the sterilized women reported that they had a tubal ligation at the time they were hospitalized for a cesarean delivery. Compared with unsterilized women, the sterilized women are characterized by relatively higher education levels and a greater likelihood of urban residence and were far more likely to have had cesarean deliveries and, therefore, to have qualified for postpartum sterilization on medical grounds.

Contraceptive use in Georgia: estimation by telephone survey.

Because household surveys are expensive and time consuming, determination of state or local family planning needs is based on national household survey estimates of contraceptive use rather than state-specific estimates. In June 1982, the University of Georgia Survey Research Center invited the Georgia Department of Human Resources (DHR) to add questions to a Statewide Omnibus Telephone Survey to obtain information on contraceptive use, source of contraception, and reasons for not using contraception. The survey used two-stage random digit dialing to select 1,737 households. From these households, we have complete information on 332 women aged 18 to 44. The definition of contraception included use by either the respondent or partner. Fifty-six percent of female respondents were using contraception; oral contraceptives (22%) and contraceptive sterilization (21%) were the primary methods used. Private sources provided 78% of nonpermanent contraceptive methods. The majority of women not using contraception reported a noncontraceptive sterilization or infertility (31%) or were pregnant, desiring a pregnancy, or not sexually active (29%). The advantages of this method over household surveys are rapid turnaround of data and relatively low cost.

Cesarean delivery in northeast region of Brazil, 1978-80.

This study presents information on cesarean section rates for the last baby born to 1,746 women in Northeast Brazil between January 1978 and the date of a 1980 household survey. For hospital deliveries, the c-section rate is 19 per cent. Rates were highest in the major urban areas and lowest in rural areas. Within residence categories, the section rate was related directly to education, early prenatal care, and delivery in private hospitals.

Assessment of tissue viability in frostbite by 99mTc pertechnetate scintigraphy.

Technetium-99m pertechnetate scintigraphy was performed in the involved extremities of six patients with severe frostbite of the hands (six cases) and feet (one case). There was good correlation between the scintigraphic findings and the extent of deep tissue ultimately requiring surgical resection. Technetium-99m pertechnetate imaging distinguishes viable from dead tissue in frostbite in a simple, noninvasive manner, and findings are easy to interpret. A persistent perfusion defect is seen in nonviable tissue.

CT diagnosis of adenocarcinoma of the appendix.

We report the CT findings in a patient with adenocarcinoma of the appendix. Previously reported cases are reviewed, and a CT appearance which is suggestive of adenocarcinoma of the appendix is presented.
