Intestinal lymphangiectasia, a disease characterized by excessive intestinal protein loss, asymmetrical peripheral edema, ascites, immunologic deficiencies, lymphocytopenia, hypoalbuminemia, imparied lymphocyte transformation, gastrointestinal symptoms and retarded growth, is the result of abnormal, distorted and obstructed lymph channels, causing rupture of intestinal lacteals from back-flow of lymph, with leakage of nutrient-laden lymph into the lumen of the bowel. A case of congenital intestinal lymphagiectasia is described, with the additional problems of allergic asthma, rhinitis, eczema and lactase deficiency. This patient, an 11-year-old child, was greatly benefited by proper allergy management (elimination diet, hyposensitization) plus restriction of fats and supplementing the diet with medium-chain triglycerides (MCT).

Nasal airway resistance (NAR) is normally asymmetrical due to the nasal cycle. The aims of this study were to determine the degree of this asymmetry in healthy subjects and those with acute rhinitis associated with common cold, and to investigate how the administration of a topical nasal decongestant (xylometazoline) influenced the asymmetry in NAR. Unilateral NAR was measured by active anterior rhinomanometry, and was shown to be asymmetrical in both healthy subjects and those suffering with acute rhinitis. The asymmetry in NAR was greater in those with acute rhinitis than in the healthy group, with a ratio between "high" and "low" sides of 2.3:1 in the rhinitis group compared to a ratio of 1.7:1 in the healthy subjects. Administration of a topical nasal decongestant caused a significant decrease in total NAR in both groups and abolished the asymmetry in NAR in the healthy subjects (ratio is 1:1 after decongestion). However, significant asymmetry of NAR was still present in the group with acute rhinitis following the administration of decongestant (ratio is 1.5:1 after decongestion). These findings show that the normal asymmetry in NAR was increased during acute rhinitis associated with common cold, and that in healthy subjects (but not in those with rhinitis) the asymmetry was abolished by administration of a topical decongestant. The results are discussed in relation to nasal sympathetic tone and nasal blood flow.

About 700 sheep died on 52 farms in north-western New South Wales and south-western Queensland over a 3 mo period. Affected animals had a marked asymmetrical swelling of the face, extending from the nostril to just anterior to the eyes. They lost condition rapidly and died within 7 to 10 days. At necropsy there was a unilateral severe necrogranulomatous rhinitis with extension of inflammation into the adjacent subcutaneous tissue, nasal septum and hard palate. Metastatic lesions were present in the draining lymph nodes and in the thorax. Histological changes consisted of a granulomatous reaction with numerous eosinophilic foci of necrosis and a diffuse, heavy, mixed inflammatory cell response. Many vessels had segmental necrosis and thrombosis. Fungal hyphae were numerous, particularly within or associated with necrotic foci. Conidiobolus incongruus was isolated from nasal tissues, parotid and submandibular lymph nodes and pulmonary lesions.

To find whether patients with chronic rhinitis might be congested because of hyporesponsiveness to adrenergic vasoconstrictive influences, we measured nasal airway resistance (NAR) in normals and allergic and non-allergic rhinitics during intravenous infusion of graded doses of phenylephrine. All responded with decreases in NAR and first evidences of NAR fall appeared no later in those with rhinitis than in normals. Nasal congestion and response were asymmetrical; absolute NAR in the low resistance side was similar in all groups and there was little response to phenylephrine. In the high resistance side, NAR reached its minimum by the time the total infused dose was 1400 mcg, indicating maximum response to drug was achieved within the dose range studied. Minimum NAR achieved on the high resistance side was higher in rhinitics suggesting residual vascular engorgement resistant to phenylephrine or non-vascular mucosal swelling. Resistance to adrenergic vasoconstriction does not appear to be the primary contributor to mucosal swelling in chronic rhinitis.

Nasal airflow is normally asymmetrical and subject to spontaneous reciprocal changes which are often referred to as the 'nasal cycle'. The nature of these spontaneous changes in nasal resistance is poorly understood and little information is available about how they are affected by nasal disease. In order to understand the changes in nasal resistance in health and disease it is important to record unilateral resistance rather than express results as total nasal resistance. Unilateral resistance is subject to continuous reciprocal changes and therefore new measurements were developed in this study in order to quantify the nasal resistance of each nasal passage. Twelve human subjects (age 19-38) with symptoms of acute respiratory tract infection (URTI) were recruited for the study which involved serial measurements of unilateral nasal airway resistance using the technique of posterior rhinomanometry over a period of six hours. Measurements were made on one day when subjects had symptoms of URTI and then repeated 6-8 weeks later when subjects were healthy. The results of this study show that all of the subjects exhibited spontaneous reciprocal changes in nasal airway resistance on both study days but that there was a significant increase in the amplitude of the changes in resistance when the subjects had symptoms of URTI with one nasal passage often becoming severely congested. In order to quantify the amplitude of the reciprocal changes in nasal resistance two new measures were used. The minimum and maximum nasal airway resistance recorded for each nasal passage during the six hour recording period (MIN NAR and MAX NAR). Mean MIN NAR with URTI was 0.4 Pa cm3s +/- 0.07 which was not significantly different from mean MIN NAR in health which was 0.36 Pa cm3s +/- 0.05 (p = 0.22, n = 20). The mean MAX NAR during URTI was 2.44 Pa cm3s +/- 0.38 and this decreased significantly to 1.36 +/- 0.17 when recorded during healthy conditions (p = 0.01, n = 20). The increased amplitude of spontaneous reciprocal changes in nasal airway resistance associated with symptoms of URTI is proposed to be due to an increased filling pressure to the nasal venous sinusoids associated with a nasal inflammatory response. A model is proposed to explain the role of the nasal sympathetic vasoconstrictor tone and nasal venous filling pressure in the control of nasal airway resistance and to help explain the periods of unilateral nasal obstruction often associated with allergic and infective rhinitis.

Medical statistics may contribute to ameliorate research by improving the design of studies and identifying the optimal method for the analysis of results. Sometimes, nevertheless, it could be misemployed flawing the benefit potential. Allergic diseases pathogenesis is recognized to be systemic but global initiatives such as GINA and ARIA documents define allergic asthma and rhinitis as organ diseases; such an asymmetrical view raises a set of known and unknown confounding that could influence the quality of the process of evidence-based decision-making (topic symptomatic therapeutic interventions versus systemic pathogenetic interventions). This article shows the first scoring system for the assessment of atopic dermatitis lesions developed in the allergy-area. A four-step severity score (FSSS) was chosen in agreement with those developed for asthma and rhinitis in global initiatives, to avoid any further differences in evaluating the severity of allergic diseases. FSSS relates each step with the objective signs of the SCORAD and rates the disease course as intermittent or persistent. A devoted electronic program has been also framed to allow a quick and simple contemporary evaluation of the SCORAD Index (Section I) and of the FSSS (Section II); the program furthermore foresees a third section named ESAS (Extra Skin Allergic Signs) (Section III) in which it is possible to check whether organs other than the skin are involved by the allergic inflammation. The limitations potential generated by a misemployment of medical statistics for clinical trials designed to establish benefits rising from specific immunotherapy for allergic diseases have been also discussed extensively.
