A survey of village poultry production in the Solomon Islands

A total of 84 farmers in 31 villages of Guadalcanal, Western, Malaita and Central Provinces of the Solomon Islands were surveyed to obtain baseline information on the current feeding practices and farmer attitudes to village poultry production. Farming of village chickens in the Solomon Islands is conducted on a small scale. Most surveyed farmers thought chickens were easy to care for, provide food for the family and was a good cash income enterprise. Some farmers were interested in keeping local chickens, but found it difficult to obtain the birds. The main feed sources are fresh coconut, copra meal, fish meal, mill run, food scraps and forage sources from the range. Some villagers believe that chickens only need to eat household scraps and did not provide drinking water. Many villagers lacked the knowledge of managing a village poultry enterprise. Some chicken houses were built by using bush materials or by purchasing construction materials. Farmers indicated they would like the government to provide funds for establishing a smallholder poultry enterprise and to provide information on feeding and management of birds.

[Malnutrition in patients with leg ulcers. Results of a clinical trial]

Chronic wounds occur in 1-2% of the population. After the age of 80 the incidence raises up to 4-5%. Leg ulcers are the most frequent diagnosed chronic wound. In this most often affected age group malnutrition develops more frequently compared to the total population. The combined presence of chronic wounds and malnutrition suggests a potential causative connection. In this clinical investigation, data evaluating the nutritional status in patients with chronic leg ulcers, derived from clinical examination, medical history and laboratory tests was analyzed for the first time for a German patient collective. Over a time period of one year we evaluated 41 patients for body mass index, diabetes mellitus, restricted mobility, diet, nicotine and alcohol use, and blood levels of vitamins, trace elements, lipids and HbA1c. We further employed the MNA-questionnaire for malnutrition. We rarely found deficiencies but often improper nutritional practices. Thus we consider that it important to evaluate nutritional status even in obese patients with leg ulcers and poorly healing wounds.

Keratosis follicularis spinulosa decalvans

Keratosis follicularis spinulosa decalvans is a rare, X-linked disorder of keratinization of the hair follicle with inflammation and atrophy associated with corneal dystrophy and other symptoms. A family with several affected members is reported. The unaffected parents were related. A 12-year-old girl and her 5-year-old brother had follicular spiny hyperkeratoses on the trunk and extremities. The girl had thinning of the eyelashes and eyebrows as well as scarring alopecia of the scalp as additional features of the disease. Both the girl and her brother had corneal dystrophy and photophobia. Two sisters aged 8 and 10 years did not show similar skin or eye findings.

[Fabry disease: demographic data since introduction of enzyme replacement therapy]

BACKGROUND AND OBJECTIVE

Fabry's disease is a rare, X-chromosome linked recessive lysosomal storage disorder. In its course multiple organ damage occurs, e.g. in skin, nerves, kidneys and heart. The disease not only markedly impairs the quality of life but also shortens life expectancy if untreated. As it is a rare and not widely known disease with considerable variability of its symptoms it is often not or only belatedly diagnosed. Since 2001, enzyme replacement has become available as an option in the causal treatment. It was the aim of this study to analyse the demography and clinical expression of the disease.

PATIENTS AND METHODS

Data were obtained from the Fabry Outcome Survey (FOS), a Europe-wide data bank for the documentation of the disease's clinical course, on 262 patients (130 males, 132 females; mean age 37.5 and 34 years, respectively on entry in the FOS) in Germany, Switzerland and Austria.

RESULTS

Typical symptoms - acroparesthesias, joint pain, hypohidrosis, fever and angiokeratoma - have their onset in childhood (mean age nine years). Symptoms start significantly earlier in males than females. The interval between onset of the first symptoms and establishment of the diagnosis is about 15 years. The severity of the clinical picture, as measured in the POS Mainz severity score index (MSSI), correlates significantly with the person's age (p = 0.0001). Main causes of morbidity and death in Fabry's disease are involvement of the kidneys or heart, the one or other occurring in 75% of patients. 171 patients (38 [65.3%]: 92 males, 79 females) are at present being continually treated with enzyme-replacement (ERT), agalsidase-a, i.e. 70.8% of all male and 59.8 of all female patients in the FOS.

CONCLUSIONS

It is of great importance for the prognosis and quality that Fabry's disease is diagnosed as early as possible and treated adequately before the onset of organ damage. If the listed symptoms by themselves remain unexplained, Fabry's disease should be considered in the differential diagnosis. National and international observational studies, such as the FOS, significantly contribute to gaining important clinical data on this heterogeneous disease.

Fabry disease and the skin: data from FOS, the Fabry outcome survey

BACKGROUND

Fabry disease (also known as Anderson-Fabry disease) is a rare, X-linked lysosomal storage disorder that is characterized by accumulation of globotriaosylceramide throughout a range of tissues in the body.

OBJECTIVES

To ascertain the prevalence and nature of cutaneous manifestations in patients with Fabry disease and to relate these to the severity of systemic manifestations of the disease.

METHODS

We have documented the dermatological features of this disease with reference to data from 714 patients (345 males, 369 females) registered on the Fabry Outcome Survey (FOS), a multicentre European database.

RESULTS

We confirm that the commonest disease manifestation is angiokeratoma. Overall, 78% of males and 50% of females had one or more dermatological abnormality, the commonest being angiokeratoma (66% males, 36% females), hypohidrosis (53% males, 28% females), telangiectasia (23% males, 9% females) and lymphoedema (16% males, 6% females). We demonstrate for the first time that the presence of cutaneous vascular lesions correlates with the severity of the systemic manifestations of the disease (pain, renal failure, cardiac disease, premature cerebrovascular disease) as assessed by a severity scoring system. Although the condition is X linked, there is a surprisingly high prevalence of abnormalities in females.

CONCLUSIONS

The FOS database is a useful epidemiological tool in establishing the variety and relevance of cutaneous manifestations in Fabry disease. The present study confirms that the presence of dermatological manifestations appears to be a marker of greater severity of systemic disease, which emphasizes the importance of the dermatological assessment of these patients.

Fabry disease in a female patient due to a de novo point mutation at position 691 of exon 5

Fabry disease is an X-linked lysosomal disorder caused by deficiency of the lysosomal enzyme alpha-galactosidase A. We report on a 32-year-old female patient with an 8-year history of vascular lesions on the hips and periumbilical region and a presumed Fabry disease without positive family history. Ophthalmologic evaluation revealed whorl-like corneal opacities. Echocardiography revealed myxomatous degeneration and prolapse of the mitral valve. DNA analysis of the alpha-galactosidase A gene confirmed the diagnosis of Fabry disease, showing a de novo point mutation at position 691 of exon 5. The patient is now obtaining intravenous enzyme replacement therapy with agalsidase alfa and remains without drug-related reactions.

Manifestation des Morbus Fabry bei einer heterozygoten Anlageträgerin

HISTORY AND ADMISSION FINDINGS

A 32-year-old woman with bilateral corneal opacities was at 9 years of age diagnosed to have reduced activity of the enzyme alpha-galactosidase A. She was admitted to our hospital because of skin lesions that had developed over the last 8 years.

INVESTIGATIONS

The clinical features included angiokeratomas on the buttocks, hips, and periumbilical region, whorl-like corneal opacity (cornea verticillata), and mitral valve prolapse. Activity of alpha-galactosidase A was reduced to about a quarter of the normal value. Histological examination revealed lipid deposits within the endothelial cells of the skin. Molecular analysis of the alpha-galactosidase A gene revealed a point mutation at nucleotide-position 691 in exon 5 (p.Asp231Asn).

TREATMENT AND COURSE

Enzyme replacement therapy with agalsidase alfa 0.2 mg/kg body-weight, infused over 40 min every other week, was initiated. So far no side effects due to the infusion therapy have been noted. The therapeutic success (reduction of lipid storage) cannot be assessed as yet.

CONCLUSION

Fabry disease results from deficient activity of the enzyme alpha-galactosidase A. Affected (hemizygous) males often show the complete spectrum of symptoms and signs and have a deficient alpha-galactosidase A activity. Occasionally milder oligosymptomatic courses are observed, when residual enzyme activity is present. In contrast to previous belief, heterozygous females may be affected in the same manner as hemizygotes and may also have a significantly reduced enzyme activity.

Akne im Kindesalter

Childhood acne has different clinical expressions which may be present from birth or manifest within the first weeks of life or after the third to sixth month of life. The condition may occur as a physiological phenomenon or may be pathological and require endocrinologic evaluation and treatment. It may be induced by drugs or ointments or due to intoxication. Severe courses with a tendency to scarring in childhood may be observed. Childhood acne may persist and develop into juvenile acne. It is likely that childhood acne may represent a risk factor for the development of severe acne in puberty.

Postural stability before and after hyperbaric oxygen treatment

OBJECTIVE

The purpose of this study was to determine the effect of hyperbaric oxygenation (HBO) on postural stability in healthy volunteers. The study was performed in accordance with treatment protocols for divers' decompression sickness and carbon monoxide poisoning.

METHODS

Twenty-one healthy male divers, aged 31 +/- 6.88 years (mean +/- SD), were tested with quantitative Romberg's test before and after HBO (90 min in a pressure chamber at an ambient pressure of 253 kPa, approximately 15 m of sea water, breathing pure oxygen). The quantitative Romberg's test is a calculation of the average sway for 50 s.

RESULTS

No difference was found between sway before and after the HBO (P < 0.05), i.e. we were unable to show that the results of quantitative Romberg's test are affected by HBO. Thus, the quantitative Romberg's test may be a valuable tool in evaluating patients with decompressions sickness, carbon monoxide intoxication and other neurological diseases normally treated with HBO.

Klinische Formen der Akne

Acne is a very common dermatosis with characteristic clinical features. It is a polymorphic disease. The clinical expression ranges from non-inflammatory closed and open comedones to inflammatory papules, pustules, and nodules. Most patients have a mixture of non-inflammatory and inflammatory lesions, although some have predominantly one or the other. Acne varies in severity from a very distressing, socially disabling disorder to a state that has been regarded as physiological by some authors. The most severe forms of acne are acne fulminans and acne inversa. Although acne may occur in all age groups, it is most prevalent during adolescence. It is not known why acne subsides in most patients but persists into adulthood in some. Certain medications may be associated with provocation, perpetuation, or exacerbation of pre-existing acne or with acneiform eruptions. Acne-like disorders include rosacea, pseudofolliculitis barbae, and other conditions that share clinical features with acne.

Does calculation of ankle brachial pressure index need revision?

Peripheral arterial disease (PAD) is a commonly encountered but a commonly under-diagnosed condition in clinical practice. Ankle brachial pressure index (ABI) is a widely used procedure in its detection. It is also a very good prognostic marker not only of PAD but also of mortality. According to the current guidelines ABI of a side i.e. either the left or the right, is the quotient of the higher of the systolic blood pressures (SBP) of the two ankle arteries of that limb (either the anterior tibial artery or the posterior tibial artery) and the higher of the two brachial SBP of upper limbs. With the currently existing method of ABI calculation, considering only the higher of the SBP of the two ankle arteries, a distal stenosis of the ankle arterial system with the lower SBP, may be missed. We suggest a modification to the currently existing of calculating ABI. The method has been termed by us as the low ankle pressure method. In this method the lowest ankle pressure between the two ankle arteries of a particular side is to be the numerator and the denominator could be the same as before. A study or a series of studies comparing our proposed method with the current one are needed to test its clinical utility.
