Treatment of psoriasis with trioxsalen baths and dysprosium lamps.
Photochemotherapeutic treatment of psoriasis with trioxsalen baths (0.5 mg/1) for 15 minutes followed by irradiation with dysprosium lamps (Osram HQI-TS) healed or nearly healed the psoriatic lesions in 18 patients within 3-5 weeks. A control area treated with the Ingram method showed a slower healing in 9 of these patients. Methoxsalen bath was not as effective in healing at the concentration used (1 mg/l). The bath method is easy to administer and cosmetically acceptable. Sensitisation to light is maximal immediately after the bath and disappears more quickly than after painting with an alcoholic trioxsalen solution. By using baths, there is less risk of accidental burns or uneven pigmentation than with the often time-consuming local application of psoralen solutions. Toxic systemic effects, which are possible with oral treatment, are less apt to occur. The dysprosium lamps give high intensity in the UV-A region. Exposure times of 10 seconds to 8 minutes are effective in the treatment of psoriasis, where both the UV-B region itself and the UV-A in combination with trioxsalen have psoriasis-healing properties.

Alternatives to hexachlorophene bathing of newborn infants.
In controlled trials newborn infants were bathed with Lactacyd, pHisoHex, Hibitane, Lanohex or tap water. Bacteriologic samples were taken from three sites (groin, axilla and cord) immediately after birth, following an initial bath with one of the test agents, and on day 3 or 5 after a water bath. Initial bathing with all agents, including water, reduced the concentration of bacteria on the skin to a similar extent. However, comparisons of bacterial flora at birth versus those on days 3 and 5 indicated differences in the actions of the various agents on pathogenic and nonpathogenic organisms. Lactacyd and Hibitane appeared to be suitable alternatives to hexachlorophene in the control of pathogenic bacteria on the skin of newborns. However, their absorption and toxicity in the newborn are unknown and, unless use of a skin disinfectant is warranted, routine bathing of newborns with tap water appears to be satisfactory.

Entrance of water into the bladder during sitz bath in elderly catheterized and noncatheterized females.
This study was conducted to determine if water enters the bladders of elderly catheterized and noncatheterized women during a sitz bath. Subjects were placed in a sitz bath containing fluorescein for 20 min. Serial urine specimens were collected at varying intervals up to 1 hr after the bath and compared to urine samples collected before the bath. No significant difference in fluorescence was found between the urine specimens in any subject which provides strong evidence that there is no detectable leakage in either group. Under the conditions of this experiment, the periurethral space was tightly sealed and did not permit passage of water.

Inotropic responsiveness of atrial myocardium bathed in Tris- or bicarbonate-buffered solutions.
Atrial muscle of guinea pigs was used to study the inotropic influences of substituting a tris(hydroxymethyl)-aminomethane-buffered solution aerated with 100% O2 for a bicarbonate-buffered solution aerated with 95% O2-5% CO2 under otherwise equivalent in vitro conditions. Basal values of isometric contractile tension and its first derivative (dT/dt) were smaller and time to peak tension and time to 90% relaxation were longer in Tris- than in bicarbonate-bathed muscles. Both groups responded similarly to changes in stimulation frequently (0.1--2.2 Hz) and Ca2+ concentration (1.0--7.0 mM); however, maximal inotropic responses to these variables were smaller in the Tris-bathed atria. The negative inotropic effects of D600 and gentamicin were greater in the Tris group. Tris-bathed atria developed pulsus alternans when exposed to Mn2+ or a reduced Ca2+ concentration, whereas pulsus alternans did not occur in the bicarbonate group. A transient increase in contractility occurred in bicarbonate-bathed atria after treatment with 0.125 mM Mn2+, but only a negative response occurred in the Tris group. Thus important, and seemingly Ca2+-dependent, differences exist between the inotropic influences of Tris and bicarbonate solutions that may affect the utility of Tris-buffered (and/or bicarbonate deprived) heart muscle for studying certain inotropic interventions.

Cold-induced vasodilatation response at different water bath temperatures in monkeys.
The response of cold-induced vasodilatation (CIVD) at different water bath temperatures was studied in 20 monkeys (3.5 kg) in a conscious state in a thermoneutral room. The animals were controlled by seating in a monkey chair, and the right hind limb up to 7.5 cm from the heel was immersed in a water bath for 60 min. Four series of experiments were conducted at water bath temperatures of 0 degrees, 4 degrees, 8 degrees, and 12 degrees C, respectively, at weekly intervals and the skin temperatures were measured from three sites in the foot. Marked CIVD response was noted from the dorsum and, to a lesser extent, from the sole of the foot, but no response was seen from the tip of the middle toe at 0 degrees, 4 degrees, and 8 degrees C water bath temperatures. The pattern of CIVD response at 4 degrees C was identical to that of 0 degrees C, but the response at 8 degrees C was poor and was absent at 12 degrees C. Three patterns of CIVD--such as hunting, proportional control, and slow, steady, and continuous rewarming--was observed. However, 15% of the animals did not exhibit any CIVD. The observations show that the CIVD response of monkeys is remarkably similar to that of man.

[Daily bath and its effect on the normal human skin flora quantitative and qualitative investigations of the aerobic skin flora (author's transl)].
The behaviour of the aerobic skin flora of the flexor sides of the forearm, under a daily repeated bath during 21 days, using two marketable bath-supplements, was investigated in 24 volunteers for its quantitative and qualitative aspects. The combined scrubbing-washing-method was used as described by Burtenshaw with Ringer's solution. After the daily baths, using Wilcoxon-test, statistically no significant changes in the total number of microorganizations and in the number of the single groups of bacteria were found in the areas investigated by intermittent samplings of the skin flora. In the analysis of the composition of the normal aerobic skin flora, however, changes were obvious in 4 volunteers. There were no clinical changes of the skin surface in any of the volunteers.

[Evaluation of bacteriological examinations of bathing-water from lakes in Carinthia (author's transl)].
The evaluation of the bacteriological examinations relates on 2330 water-samples, which were taken from 76 bathing-places of 23 Carinthian lakes in the course of 11 years. The examinations were performed for the purpose of hygienic control. After a short supervision on the methods of examination and of sampling the base of judgement is discussed. A relation to the limnological classification of the lakes could be made from the hygienic point of view. In bathing lakes in the alpine region the experiences proved a lower border-value for the indicators of fecal-charge more from the reason of lake-protection than from the reason of protection of the human health. A proposal for the judgement of bathing-water from lakes is made, including the significance of enterococci, and a scheme for recording the results is given.

[Influence of sauna baths on urinary excretion of catecholamines].
The urinary excretion of noradrenaline, adrenaline and creatinine has been studied in 22 normal young men during a sauna bath (20 minutes). The radio noradrenalinuria/creatinine is specifically increased, indicating a stimulation of the orthosympathetic system (19.6 ng.mg-1 +/- 7.9 in basal state; 30.5 +/- 15.7 in sauna bath).

Staphylococcal bacteremia and hexachlorophene bathing. Epidemic in a newborn nursery.
An outbreak of staphylococcal bacteremia in healthy, full-term neonates occurred in the newborn nursery at a large county hospital not employing prophylactic hexachlorophene bathing. Seven infants had staphylococcal bacteremia and one had omphalitis. Two of the three isolates obtained for phage typing were type 86, and the other was 3c/71. Staphylococcal colonization rate in the nursery was 64% when the outbreak was recognized; 86% of these isolates were type 86. No predominant phage type was isolated from nursery personnel. The outbreak followed a six-month preliminary study that showed a rise in staphylococcal colonization rate from 2.2% with hexachlorophene bathing to 67% with a nonhexachlorophene-containing preparation. In a community survey of infants born during the two months prior to the epidemic, seven of eight babies with lesions were infected with Staphylococcus aureus type 86.

Comparison of amino acids bathing the oxyntic gland area in the stimulation of gastric secretion.
This study was undertaken to compare the ability of L- and D-isomers of amino acids bathing the oxyntic gland area to stimulate acid secretion in conscious dogs with Heidenhain pouch (HP), gastric fistula (GF) and pancreatic fistula (PF). Acid outputs from HP were determined by an intragastric titration method when amino acid solutions were perfused into HP at various concentrations, pH values, and distention pressures. Only L-isomers of all natural amino acids were found to stimulate acid secretion, whereas D-isomers of amino acids tested were completely inert in this respect. The comparison of the secretagogue activity of amino acids shows that L-histidine among essential amino acids and glycine among nonessential amino acids exhibited the strongest stimulation of acid outputs, reaching, respectively, 52 and 40% of the maximal response to histamine. Decreasing the pH of L-histidine solution perfused into HP in sequential order from 5.0 to 1.0 resulted in a stepwise reduction of acid output, falling at pH 1.0 to about 40% of the peak response achieved at pH 5.0. Local irrigation of HP by 2% xylocaine and intravenous infusion of atropine (100 mug per kg per hr) or metiamide (2.9 mg per kg per hr) reduced but did not abolish HP response to chemical stimulation and the pH dependency of this response. We conclude that only L- and not D-isomers of amino acids bathing the oxyntic gland area stimulate acid secretion by a local, gastrin-independent mechanism sensitive to distention pressure and pH.

Clinical and microbiologic surveillance of neonatal staphylococcal disease. Relationship to hexachlorophene whole-body bathing.
Neonatal staphylococcal disease occurred in the nurseries of a university hospital three weeks after discontinuation of routine, daily, whole-body bathing of newborns with hexachlorophene. Of 16 infants who had clinical manifestations within a two-week period, 11 cases were confirmed bacteriologically. Shortly after onset of the outbreak, daily clinical and microbiologic surveillance and control measures on all infants and personnel were inaugurated. Clinical surveillance after the outbreak did not yield any new case. Average incidence of cultures positive for coagulase-positive Staphylococcus aureus was highest (13% per week) during the first three weeks of microbiologic surveillance (when hexachlorophene was not used). This is lower than that reported in most previous studies. These findings indicate the importance of scrupulous hand washing before and after handling each infant and of enforcement of other basic nursery techniques.

Unexplained acute fever after a hot bath.
An outbreak of repeated chills, fever, respiratory-tract symptoms, and muscle pain, starting 4 h after a hot bath, involved 56 persons, nearly all of whom lived in an area supplied with water from the same source. The symptoms lasted for 6--15 h. A polymorphonuclear leucocytosis was a feature of the illness. The causal agent, which has not yet been identified, was found to enter the body by inhalation. Bacteriological and chemical studies and investigation of the water for endotoxins and algae revealed nothing unusual.

The occurrence of Candida Albicans in Lake Ontario bathing beaches.
There are inherent weaknesses associated with currently used bacterial fecal pollution indicator systems. Fecal pollution indicator data would be more meaningful if supplemented with information relating to the occurrence of pathogens in recreational water. Through surveys of four bathing beaches on Lake Ontario, it was established that the opportunistically pathogenic yeast Candida albicans occurs in near shore waters. The beaches surveyed could be differentiated on the basis of bacterial fecal pollution indicator levels and numbers of the pathogens C. albicans and Pseudomonas aeruginosa. The occurrence of C. albicans and P. aeruginosa appeared to be related to elevated fecal pollution indicator levels. Maximum numbers of all parameters were observed in July and August in association with peak bather loads at the beaches. In only one instance does the data suggest that a beach was subjected to human fecal contamination.

Relationship of microbial indicators to health effects at marine bathing beaches.
Findings are described from the second year of an epidemiological-microbiological study conducted at New York City beaches as part of the U.S. Environmental Protection Agency program to develop health effects-recreational water quality criteria. Symptomatology rates among swimmers (defined as immersion of the head in the water) relative to nonswimming but beach-going controls at a "barely acceptable" (BA) beach and a "relatively unpolluted" (RU) beach were examined. Data were collected by contacting family groups at the beach on weekends, obtaining information on bathing activity, and then questioning them by phone some 8--10 days later. In addition measurements were made for a number of potential water quality indicators. It was observed that the symptom rates, categorized as gastrointestinal (GI), respiratory, "other", and "disabling" (stayed home, stayed in bed, consulted a physician), were higher among swimmers than nonswimmers. As in the pretest conducted the previous year, the rate of GI symptoms was significantly higher among swimmers relative to nonswimmers at the BA but not the RU beach. Children, Hispanic Americans, and the low-middle socioeconomic groups were identified as the most susceptible portions of the population.

[Aquamat--a proven bathing aid for the laryngectomee (author's transl)].
A device to facilitate bathing by the laryngectomee is described. The Aquamat is made up of equipment routinely used in anaesthesia and underwater diving. An airway link is made between a watertight tracheostoma and the mouth such that the patient can breath between nose and trachea. Special precautions are necessary for swimming.

Conductance changes during bath application of beta-alanine and taurine in giant interneurons of the isolated lamprey spinal cord.
(1) Input conductances of giant interneurons in the isolated spinal cord of lampreys were measured with two separate intracellular electrodes. Bath applications of 0.4--3 mM beta-alanine and taurine produced large, reversible conductance increases which were Cl-dependent. (2) Strychnine at 1--2.5 microM might be a competitive antagonist of both amino acids, but had a stronger effect on taurine. Bicuculline and picrotoxin were weak antagonists of beta-alanine and taurine in some cells. (3) A few giant interneurons desensitized after repeated application of the amino acids, but most became more sensitive. Responses to the amino acids also increase at low temperatures in in Na-free fluid, suggesting effect of uptake mechanisms.

The soluble methane mono-oxygenase of Methylococcus capsulatus (Bath). Its ability to oxygenate n-alkanes, n-alkenes, ethers, and alicyclic, aromatic and heterocyclic compounds.
1. Methane mono-oxygenase of Methylococcus capsulatus (Bath) catalyses the oxidation of various substituted methane derivatives including methanol. 2. It is a very non-specific oxygenase and, in some of its catalytic properties, apparently resembles the analogous enzyme from Methylomonas methanica but differs from those found in Methylosinus trichosporium and Methylomonas albus. 3. CO is oxidized to CO2. 4. C1-C8 n-alkanes are hydroxylated, yielding mixtures of the corresponding 1- and 2-alcohols; no 3- or 4-alcohols are formed. 5. Terminal alkenes yield the corresponding 1,2-epoxides. cis- or trans-but-2-ene are each oxidized to a mixture of 2,3-epoxybutane and but-2-en-1-ol with retention of the cis or trans configuration in both products; 2-butanone is also formed from cis-but-2-ene only. 6. Dimethyl ether is oxidized. Diethyl ether undergoes sub-terminal oxidation, yielding ethanol and ethanal in equimolar amounts. 7. Methane mono-oxygenase also hydroxylates cyclic alkanes and aromatic compounds. However, styrene yields only styrene epoxide and pyridine yields only pyridine N-oxide. 8. Of those compounds tested, only NADPH can replace NADH as electron donor.
