Multiple doses of paracetamol plus codeine taken immediately after oral surgery.

A double-blind randomized analgesic trial was carried out in 180 patients undergoing surgical removal of an impacted lower wisdom tooth. The patients received the first dose of either paracetamol 1000 mg plus codeine 60 mg, paracetamol 500 mg plus codeine 30 mg or placebo immediately after surgery during the effect of the local anaesthetic. The mean pain intensity, the duration of effect and the number of patients needing additional analgesics were all significantly dose related. In the evaluation procedure a pain intensity index was defined which took into account both the efficacy and the duration of effect. In addition, the analgesic efficacy was calculated over a 12 hour period after first medication and thereby including the efficacy of a second dose, if taken. Paracetamol 1000 mg plus codeine 60 mg followed by paracetamol 500 mg plus codeine 30 mg after around 5 hours was a very effective treatment and over 40% of these patients did not need any further pain relief during the evaluation period. In conclusion, an effective analgesic taken immediately after oral surgery reduces the total pain and diminishes the need of analgesics.

The efficacy of benorylate in postoperative dental pain.

The efficacy of a single pre-operative dose of benorylate (4 g) was determined in a double-blind, randomized, placebo-controlled parallel study in patients undergoing removal of a single impacted lower third molar. Patients treated with benorylate 4 g reported significantly less pain between 3-6 h after dosage than those treated with placebo. Overall pain scores at 6 h were significantly less in the benorylate group than the placebo group. However, overall pain scores at 12 h did not differ significantly between treatment groups. It is concluded from this study that a single dose of benorylate 4 g given immediately prior to the removal of an impacted lower third molar provides limited pain control during the postoperative period.

Bilateral surgical removal of impacted lower third molar teeth as a model for drug evaluation: a test with ibuprofen.

It was considered that double-blind crossover studies of therapeutic efficacy after acute injury could well be done in patients who required surgical removal of impacted wisdom teeth from both sides of the lower jaw. In the present trial 24 healthy patients received either placebo or ibuprofen (Brufen: 400 mg three times daily), a non-steroidal anti-inflammatory agent, for 5 days commencing the day before surgery. Treatments were given on the two occasions when impacted wisdom teeth were to be removed from one side or other of the lower jaw. A number of objective and subjective parameters were recorded for paired comparison of the post-operative courses, including swelling, trismus and pain. A mechanical device which allows simple and accurate measurement of cheek swelling is described. On the 1st, 3rd and 5th post-operative days in the ibuprofen group the measured swelling averaged 93, 89 and 82%, respectively, of that in the placebo group; the corresponding alpha-values were 0.35, 0.06 and 0.07. Patients with less swelling after ibuprofen were not always those with a high serum concentration of the drug. Ibuprofen significantly reduced pain on the day of the operation. This may at least partly account for less trismus and the preference of the patients for their post-operative courses with ibuprofen. Examination of various haematological parameters did not reveal any significant difference between the two operations. Subjective scores indicated that neither wound-healing nor bleeding was affected by ibuprofen, nor were any side effects detected.

High resolution computed tomography of the inferior alveolar and lingual nerves.

Coronal and axial high resolution computed tomography of the mandible extends facilities in dentoalveolar surgery. Preoperatively the relationship between the mandibular canal and the roots of deeply displaced third molars can be determined precisely. After surgical removal of lower wisdom teeth iatrogenic defects of the lingual cortical bone can be detected. The additional information obtained when compared with conventional radiographs is demonstrated in case descriptions. Indications for this technique, radiation exposure and implications for surgery are discussed.

The use of pain scales in assessing the efficacy of analgesics in post-operative dental pain.

Two 10 cm visual analogue scales were compared with a 0-10 point numerical rating scale and a four-point verbal descriptive scale, in assessing pain severity in twelve patients with post-operative pain following removal of an impacted lower third molar. High correlations were shown between the pain scores from the two visual analogue scales and the numerical scale, but a lower correlation was obtained when the four-point scale was compared with the other scales. Analgesic efficacy was found to be dependent on the type of scale used. The 10 cm visual analogue scale was more sensitive than other pain scales and could discriminate between small changes in pain intensity.

Paracetamol plus supplementary doses of codeine. An analgesic study of repeated doses.

A double-blind, multicentre analgesic trial was carried out in patients suffering from pain after removal of an impacted lower wisdom tooth. 266 patients were evaluated after random allocation to treatment with paracetamol 500 mg, paracetamol 500 mg plus codeine 20 mg, paracetamol 500 mg plus codeine 30 mg, or paracetamol 500 mg plus codeine 40 mg. On the day of surgery the patients assessed their own pain intensity hourly on a visual analogue scale. The analysis of the results was carried out according to the method which considered repeated dose intake. A statiscally significant dose-response relationship was obtained between the supplementary doses of codeine and analgesic efficacy. In the comparison of side effects, their frequency increased with increasing amounts of codeine. In clinical practice codeine 30 mg appeared to be the optimal supplement for paracetamol 500 mg.

Systemic diseases in age related cataract patients.

Age related cataract is the most common cause of blindness in the world. Most of these patients are elderly and are likely to have various associated systemic diseases. Higher mortality has been reported in patients undergoing cataract surgery. In order to determine the prevalence of associated systemic disease, we carried out a large eye camp based study in 6103 age related cataract patients. Seventeen percent of our patients had systemic problems. Pulmonary disease was seen in 4.3%, cardiovascular disease and hypertension in 4.1%, diabetes mellitus in 3.8%, skin disorder in 1.4%, orodental disease requiring tooth extraction in 3%, and other diseases were seen in 0.4% of the cases. Seventy eight patients (1.27%) had significant systemic complications post-operatively, 46% of whom required hospitalization in a tertiary care center. Thus, all patients undergoing cataract surgery should be evaluated for associated systemic diseases to prevent morbidity and mortality in the preoperative, operative and postoperative period.

Combined deficiency of factor V and factor VIII. A report of another case.

A patient with combined factor V and factor VIII deficiency is presented. The bleeding manifestations were: easy bruising, post-traumatic bleeding, bleeding after tooth extractions. The main laboratory feature was a prolonged partial thromboplastin time which was corrected by the addition of adsorbed normal plasma but not by the addition of normal serum, hemophilia A plasma of another patient with combined factor V and factor VIII deficiency. The thromboplastin generation test was clearly abnormal and was corrected by the addition of adsorbed normal plasma but not by addition of normal serum. Prothrombin consumption was also defective. Prothrombin time was slightly prolonged too, Thrombin time, platelet and vascular tests were within normal limits and there was no hyperfibrinolysis. Factor VIII was 8% of normal, whereas factor V was 14% of normal. Factor VIII associated antigen was normal. All other clotting factors were within normal limits. The parents of the propositus were consanguineous (first cousins) but had normal factor V and factor VIII activity and normal factor VIII antigen. The same was true for other family members. The hereditary transmission of the condition appears autosomal recessive.

The subcutaneous administration of the vasopressin analogue 1-desamino-8-D-arginine vasopressin in patients with von Willebrand's disease and hemophilia.

Twenty-one patients suffering from mild von Willebrand's disease (vWd) and patients suffering from mild or moderate hemophilia A received 1-desamino-8-D-arginine vasopressin (DDAVP) (Minirin, Ferring AG) s.c. at a dose of 0.4 microgram/kg body weight. Additionally, two hemophiliacs and 22 patients with vWd received DDAVP i.v. Within the observation period of 3 h Factor (F) VIII:C levels increased 2.4 X baseline levels in hemophiliacs, and the maximal effect was observed 3 h post DDAVP s.c. In patients with vWd post DDAVP s.c. (i.v.) a 2.7 (3.4), 2.1 (1.9) and 2.2 (2.8) fold increase for F VIII: C, F VIIIR:Ag and F VIII:Rcof was observed. In eight patients suffering from vWd with additional F XII deficiency a small and transitory but significant increase of F XII levels was detected post DDAVP s.c. No local or systemic side effects were observed. In five patients with vWd tooth extractions were performed without bleeding complications under DDAVP s.c. treatment. Two patients practiced self-treatment by injecting the drug s.c. at home. We thus conclude that s.c. DDAVP is an effective, reliable, and cost-reducing form of treatment that does not bring with it the risk of transmitting infectious diseases in patients with vWd and hemophilia and that can be administered at home.

Self-treatment with desmopressin intranasal spray in patients with bleeding disorders: effect on bleeding symptoms and socioeconomic factors.

Desmopressin (1-desamino-8-D-arginine vasopressin), an established hemostatic agent for the treatment of bleeding in mild hemophilia A, von Willebrand's disease, or platelet disorders, has mostly been given parenterally as intravenous or subcutaneous injections. Intranasal administration by spray has been shown to yield significant and highly reproducible increases in the plasma concentrations of factor VIII and von Willebrand factor and platelet adhesiveness, and to be suitable for self-administration at home, as it is easy to handle and does not involve the use of needles. This paper presents data from a questionnaire answered by 78 patients with mild hemophilia A, von Willebrand's disease, or platelet disorders, who had used the spray at home to treat bleeding symptoms. The patients experienced decreased blood loss and shortened duration of epistaxis, menorrhagia, tissue bleeding, and bleeding in connection with minor surgery or tooth extraction. The use of factor VIII concentrates was diminished, as were the number of visits to outpatient care and absence from school or work.

Plasma levels of acetylsalicylic acid and salicylic acid after oral ingestion of plain and buffered acetylsalicylic acid in relation to bleeding time and thrombocyte function.

Buffered acetylsalicylic acid (Alka Seltzer, B-ASA) and plain aspirin (P-ASA) tablets were compared as to their effects on bleeding time and platelet function in eight healthy male volunteers. Two doses (500 and 1000 mg) of each preparation were investigated in a cross-over design, each volunteer being his own control in each dose group (n=4). Both preparations disturbed platelet aggregation to the same extent. Bleeding time increased after both preparations, though significantly more after the buffered preparation than after plain acetylsalicylic acid, irrespective of the dosage. The 1000 mg dose prolonged bleeding time significantly more than the 500 mg dose, irrespective of the preparation. Kinetic analysis showed that B-ASA gave higher peak plasma levels of acetylsalicylic acid (ASA) and accordingly salicylic acid peak levels were also higher after the buffered preparation. It is concluded that B-ASA in equi-analgesic doses prolongs bleeding time more than the plain preparation. Since it is less agressive on the gastro-intestinal mucosa, its use may be advantageous in situations where acetylsalicylic acid induced loss of platelet aggregation is desired. However, the risk of prolonged bleeding--e.g. after tooth extractions--is probably higher after the buffered preparation.

[Tooth germ transplantation or gap closure--a comparative study in the loss of the first molar].

In our study 37 transplanted and 33 mesialized molars by orthodontics were clinically and radiologically compared. The teeth moved by orthodontics showed a better long-term prognosis. As vital teeth with functioning periodontal structures and only slightly shortened roots they were equivalent to healthy teeth. However, the disadvantage of orthodontic space closure is the requirement of a good compliance due to long treatment time. The prognosis of maintaining a transplanted tooth germ is uncertain. One third of the teeth showed an altered periodontium with resorption areas. The danger of a continuing resorption, as well as a late external resorption is still a risk after a long period of time and can eventually lead to tooth loss. As a treatment alternative, germ transplantation may serve as a replacement of a single missing 6-year-molar in adolescence. Orthodontic space closure is indicated at any age with an existing dysgnathia, the loss of several first molars, the loss of space and mesial tipping of the second molars.
