Hamstring Tendon Transfer for Quadriceps Femoris Paralysis

Summary Fifteen cases of paralysis of the quadriceps muscles secondary to poliomyelitis were managed by hamstring tendon transfers with an average follow-up of 48 months. Results of 13.5% excellent, 73% good, and 13.5% fair were obtained, according to an objective scoring system. Significant improvement in gait pattern, relief from brace use, or “hand-on-thigh” ambulation was seen in all cases. A mean extension lag of 30° was observed in patients examined in the sitting position. Lack of active terminal knee flexion, prohibiting comfortable floor sitting, was the main untoward effect and the source of complaint in four patients.

Conflict at the Rural/Urban Interface: Mushroom Farms and Composting in a Suburbanizing Environment

Major complaints, nuisance suits, and vandalism threaten the ability of farms in suburbanizing areas to survive as development occurs around them. This is a particular concern in one county in southeastern Pennsylvania, an area of rapid population growth but also the nation's most productive mushroom producing area. This study examines mushroom growers' indications that on-farm composting is a major source of complaints from nonfarming neighbors. The study found that the size of the farm and the number of homes nearby were significantly more important factors than composting in explaining which mushroom farms receive complaints.

Tips for young players in hair restoration surgery

Unsightly scars in the donor site or lumpy grafts in the recipient region are often a source of complaints and, occasionally, a basis for litigation. Because most unsightly scarring is a result of abnormal patient scar reaction, it would be useful if there was some way of forecasting a patient's

Materials traceability

Discusses the concept of materials traceability showing how it can produce up to 80 per cent of the benefits of total quality management. Identifies a number of critical control points (CCPs) in any production process. These are the points at which things could go wrong and where the source of complaint may be found. Demonstrates how a sophisticated system can record data at each of these CCPs leading to improved efficiency.

Midwives in Niger: An uncomfortable position between social behaviours and health care constraints

Maternal mortality rates are very high in developing countries. In Niamey, the capital of Niger, maternal mortality rate is 280/100,000, in spite of a high concentration of health services and of health personnel. Several studies demonstrated that the efficiency of maternal health services was low, both because the quality and the quantity of work were insufficient. The usual response to the poor performances of health services in developing countries in mainly technical. If improvement of the training of health personnel and re-organization of health services are necessary, they are not sufficient. A good effectiveness of care cannot be achieved without a mutual confident relationship between providers and patients. Focus group discussions were held in Niamey with women users of maternal health services, with student midwives and experienced midwives. Sources of complaints between providers and patients appeared to be numerous. However, they are centered around two themes, delivery techniques and cultural requirements, which correspond to two types of constraints: technical constraints and social representations and practices of the population. A description of traditional practices and beliefs related to delivery were obtained through discussion groups with old women and traditional birth attendants (TBAs). Both women and midwives are tied up by the same social rules (e.g. linguistic taboos, respect and shame) but technical constraints force midwives to violate those rules, making the application of their technical skills very difficult. Thus, the mutual relationship between users and providers is source of dissatisfaction, which often degenerates into an open confrontation. Midwives must learn how to implement obstetrical techniques within specific cultural environments.

Emissions of Indoor Pollutants from Building Materials—State of the Art Review

Indoor air contaminants from building materials are often the major source of complaints. The demand for materials with low-emission characteristics is on the rise, along with the need for more sensitive and reliable emission studies. Air quality and product testing standards need to be revised and updated to take into account not only health effects, but also comfort considerations, especially for hypersensitive occupants. Modern building materials, including sealants and adhesives emit a rainbow of contaminants at ambient temperatures. The bake-out and demand controlled ventilation techniques are some attempts in reducing emissions after the materials have been installed. This paper discusses the state of knowledge of building materials emissions and describes techniques to reduce the emission rates.

Industrial Discipline: A Suitable Case for Treatment

There is no clear evidence that British workplaces are any nearer the achievement of being representative bureaucracies as far as disciplinary rules are concerned as public policy initiatives are to placing the emphasis on a corrective as opposed to a punitive approach to Industrial discipline. The concept of industrial discipline is examined alongside forms of management control. Management aims and objectives and the difficulties management encounters in this sphere are considered. Worker attitudes and sources of complaints are discussed in the context of the type of involvement unions should have in the discipline process. The trend towards formalisation is explored and Its reasons, advantages and disadvantages discussed. Discipline Is still conflict‐prone and the reasons for this and ways to minimise it are examined. The work is based on an extensive review of the literature and an ESRC research project that examined disciplinary practice in eight different workplaces. Findings are based on interviews with personnel, line managers and shop stewards and examination of rule books, procedures and disciplinary records. The project was carried out during 1981–1983.

A statistical model for predicting the probability of complaints from army weapons noise

U.S. Army environmental noise assessments use a statistical average (DNL) to evaluate the impact of heavy weapons noise on nearby residents, but experience has shown that variability above the average is the source of complaints. To assist environmental planners and range control officers in predicting complaints from a specific configuration of range and weapon, a BASIC language program short enough for a personal computer has been developed. Users begin by choosing the weapon from a menu and after defining the coordinates of the firing point, target, and observer, they have the option of: (1) entering a noise level and receiving the probability of that level being exceeded at the observer's location, or (2) entering an exceedance level and receiving the noise level associated with that exceedance level. Noise levels are then compared with the criteria used in the successful complaint management program at the Naval Surface Weapons Laboratory, Dahlgren. Onsite blast noise measurements taken over the past decade are used to demonstrate the predictive validity of the model.

Use of a viewdata system to collect data from a multicentre clinical trial in anaesthesia.

The interactive electronic information storage and transmission system PRESTEL was assessed as a method of recording and collecting patient record forms from a multicentre trial in anaesthesia. PRESTEL terminals were provided in anaesthetic centres around Britain and all data handled by this public viewdata service, which connects users by telephone to a central computer. The trial was of a new analgesic supplement, alfentanil, and confirmed more rapid recovery of patients as compared with that after traditional anaesthesia with halothane. Advantages of the system were manifold and included reducing the need for the trial monitor to visit the trialist, an electronic "mailbox," confidentiality, and the ability immediately to identify violations of study protocol. No participant found the system too difficult to use, though the small keyboard was a source of complaint. Despite the initial cost of the system its utility vastly outweighs traditional methods of data collection.

Noise and Vibration Generated by Underground Railways

Recent expansion of railway networks has led to complaints of noise and vibration. Measurements were made at a number of points along the Musashinonansen Freight Line to determine the vibration from the underground line and the associated noise. It was found that the main source of complaint arises from ground borne vibration leading to secondary radiation of low frequency noise.

Balancing radiator systems

When the water is incorrectly distributed throughout the system, radiator central heating can be a source of complaints and wasteful of energy, expecially in large installations. The problems involved and the likely remedies are discussed here by an engineer at the Danish Building Research Institute, which has devised special equipment for measuring water flow in pipes.

Quality variations in regenerated cellulose and acetate fibres and yarns

Fibre quality has improved appreciably, tenacity norms are higher, and the norms for irregularity of individual fibre properties and the permitted proportion of fibre faults have been reduced but the fibres and yarns now being produced still fail to meet the increasingly stringent specifications imposed by the users. The physico-mechanical indices are not usually a source of complaint but the faster technological processes now in use, notably the high processing speeds, call for fibres and yarns with improved properties so that the light industry demands a still lower proportion of fibre faults.

A roller-block for measuring lobing

The ball-block has been introduced as a substitute to the V-block for the detection of lobing in cylindrical components. However, “digging” of the balls has been a source of complaint by the users of the ball-block. An equivalent roller-block using two master rollers instead of the four balls of the ball-block, is suggested in the present paper. For the detection and indication of lobing, the workpiece is rotated on the rollers under a clock indicator. The appropriate relations between the indicated values and the true amount of lobing for various numbers of lobes and different roller (or ball) sizes are worked out. Design data regarding the size of rollers (or balls) in relation to the workpiece size is given for the indication of the true value of lobing. Further data is given for the more favourable indication of double the true value of lobing.

Sulphide Staining Inside Tinplate Cans and its Prevention

Production of sulphides of iron or of tin inside tinplate cans filled with sulphur-containing foodstuffs may cause stains which, although harmless, are a source of complaint from consumers. The formation of iron sulphide is widelythought to be a conversion by H2S or HS-ions of a preliminary Iron corrosion product. Evidence now obtained suggeststhat tm sulphide is formed by a corresponding process and that Its direct formation from metallic tin or tin oxide is unlikely. Formation of tm sulphide may be prevented by screening the tin from the corrosive agent with lacquers or with the better passivation films formed by cathodic treatment in dichromate solutions on tinplate production lines. It is shown that the effectiveness of the protection that is given by passivation films depends on the amount of metallic chromium that they contain. Films which contain only oxides of tin and/or of chromium can give a useful degree of protection only when they are relatively thick.

Impact-Sound Transmission through Concrete and Wood-Joist Floors

A wide-spread source of complaints by apartment dwellers is the transmission of impact noises through floors. A program has been conducted to determine the impact-sound-transmission characteristics of concrete and wood-joist floor constructions. The concrete constructions consisted of the 12-in. slab forming the roof of a 10 000-cu-ft reverberation room with test panels of various types and areas up to 16 sq ft laid over the slab. The wood constructions were built into a 10-ft-sq opening in the roof of the reverberation room. Impact-transmission tests were conducted according to ISO/R 140-1960, using the standard tapping machine specified. The criterion used thus far for evaluation of the test results has been the British grade I and II curves that denote relative degrees of apartment-dwellers' satisfaction as determined by extensive field surveys. The grade I curve can be met with a number of practical constructions over a concrete slab, for which data are presented. In wood-joist construction, the grade I requirement is easily met at the higher frequencies, but equivalent low-frequency performance is difficult or impossible to attain because of the inherent lack of mass and rigidity of wood construction in comparison to concrete.

Health insurance coverage of hospital care for mental illness.

SOMIE HEALTH INSURANCE PLANS either exclude mental illness from coverage or give less coverage than for other types of illness. These practices are of importance to the subscribing public, hospitals, and the medical profession and are frequently a source of complaint. It is the purpose of this article to describe the existing situation and to deal with some of the problems involved in providing health insurance coverage of hospital care and of physician service in the hospital for mental illness.*

Ring dermatitis; primary irritation from the action of salt on jewelry alloys.

A complaint from many people is the tendency to develop irritations under and around their rings. Hot weather, with associated sweating, is an important factor in the appearance of such irritation. Rings are not the only source of complaints. Other kinds of jewelry, metal ornaments, fasteners, and pins are just as likely to produce irritations. Dermatitis from rings has been of special interest because of the prevalence of hand eczema. Quite often the initial site is the ring finger. When a rash appears on the left fourth finger, a number of patients change the ring to the right fourth finger and forthwith present a dermatitis on both hands. Sometimes the duration of a hand eruption dates back to a class ring worn in the early teens. Of added import is the fact that every year a fair number of patients experience a spreading dermatitis whose origin was overtreatment

The ”Roche” Friabilator*

Breakage of medicinal tablets is a source of complaint and is an economic waste. It is desirable, therefore, to formulate and produce tablets which will survive handling in production and in distribution. Estimation of the ability of tablets to survive such handling has been difficult because of the lack of an adequate test to measure the property. A new apparatus which measures resistance to abrasion and shock has been designed. A weighed sample of tablets is subjected in the apparatus to a tumbling action and to the shock resulting from a free-fall of six inches. The loss of weight suffered is a measure of the friability of the tablets. The test has been found useful for the control of plain, compressed tablets, and especially for evaluating new formulations.

Rotary, oscillating & reciprocating seals

In recent years, considerable advances have been made in the prevention of leakage of liquids and oils past moving surfaces. Leakage is the most common source of complaint with regard to hydraulic machinery, in which field the authors have had considerable experience. The subject covers a wide field and, has been limited by excluding hydraulic joints. For the purpose of these papers, a hydraulic seal is defined as one whose function it is to prevent the leakage of liquid between surfaces having relative movement.

Hydraulic Seals

Leakage is the most common source of complaint with regard to hydraulic machinery. During recent years considerable advances have been made in the prevention of leakage of liquid past moving surfaces. New materials and constructions have come into common use, and there has been a small but valuable amount of research into the action, wear and friction of packings and seals. The object of these papers is to initiate a comprehensive discussion of existing knowledge on the subject, which will perhaps indicate the fields to which future research and development might best be directed. The authors' experience has been mainly in connexion with hydraulic machinery in which oil is the working medium; in this field particularly, the improvement of sealing methods has been very marked. It is hoped that contributors to the discussion will also deal with water, acids, and other liquids, and with the special problems encountered owing to high temperature, corrosion, dirty liquids, etc. As the subject covers a wide field, it has been limited by excluding hydraulic joints. For the purpose of this paper, a hydraulic seal will be defined as one whose function it is to prevent the leakage of liquid between surfaces having relative movement.
