Forty-one patients requiring gingivectomy in one or more areas were used for a clinical evaluation of three different periodontal dressings. Sixty-five operations were performed. Whenever possible different dressings were tested in the same patient. The type of dressing was chosen randomly, applied by one operator and left in place for 1 week. The patients were supplied with analgetic tablets. At day 7 the condition of the dressing was evaluated before removal. The patients' subjective experiences of pain, swelling, bleeding and fever, as well as use of pain relieving tablets, were recorded. The wound was evaluated with regard to the degree of epithelialization, presence of denuded bone and granulation tissue. The tendency to bleeding and the sensitivity of the teeth to a water spray (15 degrees C) were tested. At day 14 and 21 the same evaluation procedure was repeated. In addition the presence of plaque in the operated area was assessed. One of the dressings more frequently induced pain and swelling than the others. Tablet consumption was also higher when this dressing had been used. No statistically significant differences were found in the clinical assessment of wound healing, tendency to bleeding and the sensitivity of teeth.

A recently introduced polymer preparation (Iodoplex) is described. It is based on a new type of hydrophilic polymeric carrier into which iodine can be incorporated to the extent of 50% or more. Its main feature is that the polymer and the petroleum jelly base are water-insoluble. The iodine is slowly released from the polymer by body fluids, which are rich in protein and dead cells. Iodine has been found to be useful in the treatment of donor sites; no pain or discomfort attends its use, and the dressing peels off easily from the healed epithelium. A controlled study comparing iodoplex-impregnated and scarlet red-impregnated gauze on donor sites was carried out, and the use of Iodoplex was found to have some real advantages over scarlet red.

The Brompton mixture is widely used as an effective method for controlling pain in cancer patients. In a double-blind crossover trial a standard Brompton mixture containing morphine, cocaine, ethyl alcohol, syrup BP and chloroform water was compared with morphine alone in a flavoured aqueous solution; both were administered orally. Pain was measured by means of the pain intensity index of the McGill Pain Questionnaire. Ratings of confusion, nausea and drowsiness were obtained from both the patients and their nurses and relatives. The data showed that there was no significant difference between the Brompton mixture and morphine administered orally for any of the variables. Both relieved pain effectively in about 85% of the patients.

A double-blind 4-week trial of sodium oxyferriscorbone versus placebo (distilled water) was conducted in 46 outpatients with endoscopically confirmed gastric ulcer. Ulcer healing occurred in 15 of 20 patients receiving sodium oxyferriscorbone (75%) and in 7 of 20 patients receiving placebo (35%). Patients receiving sodium oxyferriscorbone experienced less pain and required less antacid than those receiving placebo (P less than 0.05). Side effects were reported in 12 patients, 7 while receiving sodium oxyferriscorbone and 5 while receiving placebo. Six patients did not complete the study due to ulcer complications. Routine laboratory tests revealed no persistent abnormalities that could be related to the treatment. Five placebo-treated patients that were therapeutic failures were switched to sodium oxyferriscorbone and healing was observed within 3 weeks. It is concluded that sodium oxyferriscorbone is effective in enhancing healing of gastric ulcers.

Water balance is tightly regulated within a tolerance of less than 1 percent by a physiologic control system located in the hypothalamus. Body water homeostasis is achieved by balancing renal and nonrenal water losses with appropriate water intake. The major stimulus to thirst is increased osmolality of body fluids as perceived by osmoreceptors in the anteroventral hypothalamus. Hypovolemia also has an important effect on thirst which is mediated by arterial baroreceptors and by the renin-angiotensin system. Renal water loss is determined by the circulating level of the antidiuretic hormone, arginine vasopressin (AVP). AVP is synthesized in specialized neurosecretory cells located in the supraoptic and paraventricular nuclei in the hypothalamus and is transported in neurosecretory granules down elongated axons to the posterior pituitary. Depolarization of the neurosecretory neurons results in the exocytosis of the granules and the release of AVP and its carrier protein (neurophysin) into the circulation. AVP is secreted in response to a wide variety of stimuli. Change in body fluid osmolality is the most potent factor affecting AVP secretion, but hypovolemia, the renin-angiotensin system, hypoxia, hypercapnia, hyperthermia and pain also have important effects. Many drugs have been shown to stimulate the release of AVP as well. Small changes in plasma AVP concentration of from 0.5 to 4 muU per ml have major effects on urine osmolality and renal water handling.

A review is presented of work on envenomation by stonefish (Synanceja spp.), which represent not only a danger for the inhabitants of tropical coasts but also for tourists. Stonefish are common in shallow water of reef areas by the shores of the Indian and Indopacific Ocean. The bizarrely shaped fish is often taken for a weed-covered stone and accidents occur when swimmers, divers or fishermen step on the stings of the dorsal fin. These stings are provided with poison glands. The venom has neurotoxic, myotoxic and hemorrhagic effects. The case of a 39-year-old diver is cited who suffered a stonefish stab which lasted for several weeks. Generally envenomations by Synanceja cause severe local pain and enormous swelling of the limb; systemic symptoms as usually found with neurotoxins are common; death may occur by shock, by paralysis of the diaphragm or cardiac arrest. For first aid bathing of the limb in hot water is recommended. Clinical measures are local analgesia, local neutralization of the venom, if possible antiserum therapy and intensive care with symptomatic treatment of systemic complications. The most effective prevention is adequate foot protection when wading in the sea.

Topical instillation of Adriamycin, 40 mg in 20 ml sterilized distilled water, was performed in 20 cases of bladder tumors every day for two weeks. In 8 cases (40%) the tumors disappeared completely, while in 5 cases (25%) tumors were reduced in size, but in 7 cases (35%) there was no effect. Therefore, the rate of effectiveness was 65%. The local bladder reaction and urethral pain were noted in all cases, as a result of which the therapy was interrupted in 2 cases. Abnormal values of red blood cells, white blood cells and platelets were not observed. In 3 cases the serum level of Adriamycin was only trace 1 or 2 hr after instillation. In conclusion, Mitomycin C was thought to be superior to Adriamycin as far as the effectiveness and irritability on the normal bladder epithelium were concerned.

The analgesic effect of nicomorphine in two different solutions was tested in 120 patients after cholecystectomy. The patients were divided into three groups: group I was given nicomorphine diluted with water, group II nicomorphine diluted with propylenglykol, group III propylenglykol alone. The degree of pain sensation was determined by interrogation. Pulse, respiratory rate, blood pressure as well as capillary pO2 and pCO2 were measured 10 and 30 minutes after medication. No difference in pain relief could be established in the two groups receiving nicomorphine. Respiratory depression with a significant decrease of respiratory rate together with an increase of pCO2 was observed in the two nicomorphine groups. In the placebo group there was no significant change in the tested parameters. A small decrease of pO2 was observed in all patients after laparotomy.

Responses of 18 neurones of the first cortical projection visual area to photic and nociceptive stimulation (plunging of a paw into hot water) were studied in immobilized cats. The increase in blood pressure recorded in the femoral artery served as index of pain response. During plunging the paw into hot water 14 neurones showed an increase in the frequency of spike activity by 3 times as compared to the background. The changes in spike activity preceded the increase in the arterial pressure by 1-2 sec. 12 out of 14 neurones also responded to a photic stimulus. After administration of chlorpromazin the neuronal response to the nociceptive stimulus was blocked, but the response to the photic stimulus persisted. A conclusion is made that pain excitation reaches cortical visual neurones through functional connections, which are different from those functioning during activation of the same neurones with specific photic stimulus.

This communication describes the development of a protocol for the air caloric stimulus for vestibular testing. The protocol is based on matching the peak responses of air and water caloric stimuli and minimizing subject discomfort. Air stimulus temperatures of 30 and 44 degrees C are used, and these appear to minimize subject complaints of pain with the test. Composite data are presented from 16 normal subjects who were tested with the protocol. A comparison is made with their responses to a standard water protocol. Test-retest data for both air and water protocols are also presented, and these data indicate similar day-to-day variation in the two methods. On the basis of the work presented, it is concluded that the air protocol produces responses equivalent to that of standard water calorics in a group of normal subjects. Neither test was found, in the present experiments, to be particularly sensitive.
