Primary ovarian hydatid disease in the Kingdom of Saudi Arabia

Human hydatid disease is caused by Echinococcus granulosus. Its distribution is world wide and it affects mainly the liver, but other organs could be involved. Primary involvement of pelvic organs is very rare. This is a case report of primary ovarian hydatid disease in a postmenopausal woman, diagnosed postoperatively. Surgical excision was adequate. Ultrasonography, particularly high frequency trans-vaginal, computed tomography scan and, more recently, magnetic resonance imaging are more frequently used in the diagnosis of Echinococcus cyst. They appear more reliable than many of the old tests of varying sensitivities. Whereas, there are anecdotal reports of obstetric and gynecological manifestations of echinococcosis from some Middle Eastern and North African countries, this is the first of such report from the Kingdom of Saudi Arabia. It is unclear why there is a lack of information about this condition among Saudi women, even though socio-cultural attitude to female involvement in sheep farming and animal husbandry is similar to that in other Arabic and Islamic countries. We endorse the recommendation that every gynecologist, radiologist and histopathologist should maintain a high index of suspicion for hydatid cyst, whenever a septate cystic pelvic mass is found.     

Factor analytical study of the short version of the World Health Organization Quality of Life Instrument

The domains of the 26-item World Health Organization Quality of Life Instrument (WHOQOL-Bref) contain heterogeneous items and do not encompass the logical constructs of subjective quality of life (QOL). We compared the WHO 4-domain and 6-domain models of the WHOQOL-Bref with the 8-domain model that we obtained from factor analysis (FA). Data from 118 recently recovered Nigerian psychotic patients were used in confirmatory factor analysis (CFA) to assess goodness of fit and clarity of concept. Our FA model had superior goodness of fit for CFA and provided clarity of concept. Analysis of the WHOQOL-Bref should consider the domains from FA and include 'overall QOL' as an item and dependent variable. Subjective QOL is an aggregate of the following constructs: satisfaction with life circumstances; fulfillment of needs, and opportunity for experience in the milieu.     

A comparison of the therapeutic efficacy and tolerability of etoricoxib and diclofenac in patients with osteoarthritis

OBJECTIVE: To evaluate and compare the efficacy and tolerability of etoricoxib and diclofenac in patients with osteoarthritis of the knee or hip. METHODS: In this 6-week double-blind, active comparator controlled, parallel-group study eligible osteoarthritis patients were randomised to receive either etoricoxib 60 mg once daily (n = 256) or diclofenac 50 mg three times daily (n = 260). The primary study endpoint was the Western Ontario McMaster osteoarthritis index (WOMAC) pain subscale. Other endpoints included were the WOMAC stiffness and physical function subscales, and the Patient's Global Assessment of Response to Therapy (PGART) questionnaire. Early efficacy was evaluated using WOMAC first question (pain walking on a flat surface) and PGART 4 h after the morning dose of each drug on days 1 and 2. Rescue medication (paracetamol) used was also recorded. The study was designed to show comparable efficacy between etoricoxib 60 mg once daily and diclofenac 50 mg three times daily with respect to the primary endpoint and was conducted outside the United States at 67 centres in 29 countries. RESULTS: Etoricoxib (60 mg once daily) was comparable in efficacy to diclofenac (150 mg daily) on all the above parameters. The one exception was in the assessment of early efficacy where etoricoxib demonstrated significantly greater benefit within 4 h of taking the first dose on the first day of therapy (p = 0.007) as evaluated by the percentage of patients with good or excellent (PGART) responses. The treatment effects of both drugs were similar by the time day 2 was reached and were sustained throughout the 6 weeks of therapy. Both treatments were generally well tolerated. CONCLUSIONS: Etoricoxib is clinically effective in the therapy of osteoarthritis providing a magnitude of effect comparable to that of the maximum recommended daily dose of diclofenac. The onset of clinical benefit with etoricoxib on day one is more rapid than that of diclofenac. Both drugs were generally well tolerated.     

Maternal Tetanus at the University College Hospital in Ibadan Nigeria: A 15-Year Retrospective Analysis

Objective To determine the characteristics of women with maternal tetanus, pattern of presentation and outcome of management. Methods A total of 19 women were managed with maternal tetanus between 1990 and 2005 from the University College Hospital in Ibadan Nigeria. A retrospective study was performed. The medical records of all women managed as a case of maternal tetanus were retrieved from the central record department of the hospital. The pattern of presentation, characteristics of women, the duration of hospital admission, tetanus toxoid immunization, and outcome of care were measured. Results The records of 18 women managed were analyzed. The mean age at presentation was 25.2 ±5.3 years. The patients were mostly single, nulliparous and had primary school education. The maternal tetanus cases seen mainly complicated induced abortion while 5 and 2 other cases were due to childbirth complication and leg wound respectively. The portal of entry of the remaining 3 cases could not be ascertained. None of the patient managed had complete immunization schedule. The average duration of admission was 11.2 ± 6. 7 d. Five women had intensive care with 3 of them requiring ventilatory support. The case fatality rate was 66. 7%. The only factor that significantly improved survival was presence of generalized spasm at presentation （P=0.006） Conclusion The occurrence of maternal tetanus is a reflection of low quality of health care delivery and lack or inefficient routine immunization coverage in any community.     

Telethermographische Untersuchungen der Wundnaht im Tierexperiment

It is known from clinical practice that the healing of wounds is influenced by the type of wound suture applied. In general, the scar resulting from an intracutaneous suture looks better than that produced by an uninterrupted suture or by knotted suture. With respect to the appearance of the scar, the intracutaneous suture is normally superior to other wound sutures. As suggested by the results of our investigations, this may be due to an undisturbed microcirculation within the wound. Thermovision shows that a local temperature increase appears sooner in a wound closed by intracutaneous suture, whereas the temperature increases more slowly in case of uninterrupted or knotted suture. We suppose that the alterations of microcirculation in a wound closed by one of the latter types of wound suture can be considered as disturbance in blood circulation which may be followed by healing disturbances and proliferations of connective tissue.     

Percutaneous drainage access: a simplified coaxial technique

We describe an access technique that we have used in 150 nephrostomy and biliary drainage procedures and for access to some abscesses and viscera. The system provides safe coaxial access with a 22-gauge removable hub needle, which then acts as a guide wire and is replaced by an 18-gauge cannula. A major advantage is that only one guide wire is used (0.038-inch) for the entire drainage procedure. No significant complications have occurred to date with this method.     

Molluscicidal trials and correlation between the presence of Tetrapleura tetraptera in an area and the absence of the intermediate hosts of schistosomiasis and fascioliasis in southwest Nigeria

A schistosomiasis research project, carried out in Southwest Nigeria, yielded data by which it was possible to relate snail recovery from potential transmission sites to the presence or absence of Tetrapleura tetraptera. A significant negative correlation with snail numbers was found for distance of T. tetraptera from transmission sites and fruiting of the trees when these variables were tested individually. There were no significant differences between individual variables such as pH, Ca2+ concentrations and temperatures for these snail habitats but these variables produced significant positive correlation with the number of snails recovered. Thus, the presence of T. tetraptera appeared to be the most important limiting factor for the presence of snails. Aqueous extracts of T. tetraptera were effective as a molluscicide against Bulinus globosus and Lymnaea natalensis. However, pollution of the environment by oils reduced or abolished the molluscicidal activity of T. tetraptera. The results indicate that the planting of T. tetraptera has potential for the local control of schistosomiasis.     

Cerebrospinal fluid rhinorrhea: depiction with MR cisternography in dogs

Studies on the effects of oxamniquine on autonomic transmissions

The effects of oxamniquine have been investigated on parasympathetic and sympathetic transmissions using in vitro and in vivo laboratory models. Oxamniquine (3.6 X 10(-5)-5.5 X 10(-4) M) depressed or abolished electrically-evoked contractions of the isolated chick esophagus and isolated vas deferens muscle preparations. At the same concentration (3.6 X 10(-5)-5.5 X 10(-4) M) levels, the drug also reduced or abolished the indirect, electrically-provoked twitches of the rat isolated phrenic nerve-hemidiaphragm muscle preparations and contractions of the cat nictitating membrane induced by pre-ganglionic cervical sympathetic nerve trunk electrical stimulation in vivo. These results strongly suggest blockade of sympathetic and parasympathetic transmissions by oxamniquine.     

Langzeitergebnisse nach lumbalen Bandscheibenerkrankungen

The therapeutic results of operatively and conservatively treated patients with lumbar disc syndromes were reviewed in a retrospective study. The patients were treated during a 10-years period (1976-1985). A total of 330 patients with lumbar disc prolapses were treated in the hospital during this period 44% were treated surgically. The data on 100 operated and 100 conservatively treated cases, registered in this random test sample, have been compared with respect to: pain; neurological deficits; subjective problems and sociomedical questions. The average patient age of both groups was about 41 years, and the patients predominant were male (about 70%). The therapeutic results of both operatively and conservatively treated patients were good, which is also by the high percentage of employment (80%-90%) in the two treatment groups. The critical evaluation showed more neurological disturbances and limited vocational activity in the group of cases operated upon. More than 70% of the operated cases showed radicular syndromes of the follow-up examination although it was not of essential functional importance. The period inability to work and the percentage of disablement were also much higher in this group. The pain symptoms were particularly relevant in our examination. Only 12%-16% of the patients in the two groups that took part in the follow-up examinations reported freedom from pain. It was apparent that atypical pain syndromes were correlated with personality psychological disturbances. Nearly one-third of our patients mentioned psychological problems. The prognosis of the conservative treatment of lumbar disc prolapse was equivalent to operative therapy (disregarding the absolute indications for operations). There were no definite advantages found for either of the two methods of treatment. The necessity for a specialized follow-up treatment of patients with sciatica due to herniated lumbar discs is discussed, and differentiated selection for operative therapy is given. Here the treatment of pain should be considered most important.
