Frequency of extraintestinal manifestations in patients with inflammatory bowel disease in Northwest Greece and review of the literature.

BACKGROUND: Inflammatory bowel disease mainly affects the bowel but also has extraintestinal manifestations. AIMS: To report the frequency of extraintestinal manifestations in patients with inflammatory bowel disease in Northwest Greece. PATIENTS; The data files of 256 inflammatory bowel disease patients (diagnosis between 1983-19971 were analysed. METHODS: Retrospective investigation of patient files. RESULTS: In patients with ulcerative colitis: 13.9% (30/215) had developed skin manifestations, 6% (13/215) had kidney stones, 1.39% (3/215) had iridocyclitis, 1.86% (4/215) had primary sclerosing cholangitis, 4.18% (9/215) had sacroiliitis, 8.31% (18/215) had peripheral arthalgias, 2.3% (5/215) had colitic arthritis and finally 1.39% (3/215) had deep vein thrombosis). In patients with Crohn's disease: 24.3% (9/37) had developed skin manifestations, 5.4% (2/37) had kidney stones, 2.7% (1/37) had iridocyclitis, 16.2% (6/37) had sacroiliitis, 8.1% (3/37) had peripheral arthralgias, 5.4% (2/37) had colitic arthritis and, finally, 8.1% (3/37) had deep vein thrombosis. Sacroiliitis (p = 0.01), deep vein thrombosis (p = 0.04) and erythmema nodosum (p = 0.01) were more common in patients with Crohn's disease. CONCLUSIONS: Extraintestinal manifestations are not rare in patients with inflammatory bowel disease, especially in Crohn's disease patients, in our area, but have, generally, a mild profile.

A prospective evaluation of dermatological side-effects during alpha-interferon therapy for chronic viral hepatitis.

OBJECTIVE: Alpha-interferon therapy may occasionally account for immune-mediated phenomena. This study was conducted in an attempt to investigate the incidence of the development of immune-mediated dermatological diseases during alpha-interferon therapy in patients with chronic viral hepatitis. The latter has not been evaluated prospectively, whereas most of the previous studies examined small numbers of interferon treated patients or consisted of case reports. DESIGN: A prospective case-control study. SETTING: A tertiary referral centre. PARTICIPANTS: One hundred and twenty consecutive patients with chronic viral hepatitis (67 with hepatitis B, 45 with hepatitis C, six with both hepatitis viruses, and two with delta hepatitis) were evaluated during a course of alpha-interferon therapy. In addition, 120 consecutive patients with chronic liver diseases (disease control group), who had never received alpha-interferon therapy, were evaluated during the period of the study (at least for 12 months). INTERVENTIONS: Recombinant alpha-interferon at a dose of 4.5 or 5 million units subcutaneously (s.c.) three times per week for 6 to 12 months was administered to patients with hepatitis B. The patients with chronic hepatitis C were treated with 3 million units s.c. three times per week for 12 to 18 months. The patients with chronic hepatitis B and C infections received 4.5 million units for 6 months, and then 3 million units for an additional 6 to 12 months. Finally, the patients with chronic delta hepatitis received 5 million units for 1 year or more. MAIN OUTCOME MEASURES: To assess prospectively the incidence of these dermatological disorders during alpha-interferon therapy and to estimate if there is any relationship between their development and the clinical, laboratory or other characteristics of the patients with chronic hepatitis. RESULTS: Three to 6 months after the initiation of alpha-interferon three patients with chronic viral hepatitis (two with hepatitis C and one with hepatitis B) developed lichen planus, whereas one patient with hepatitis C developed relapsing aphthous stomatitis. The development of these disorders was significantly associated only with the presence of antinuclear antibodies before the initiation of alpha-interferon (P=0.000000). None of the patients from the disease control group had such a manifestation during the follow-up. Lichen planus resolved after the end of therapy in all of them. In contrast, therapy was discontinued in the patient who developed aphthous stomatitis, owing to the painful lesions. CONCLUSIONS: This study demonstrated that alpha-interferon may rarely (3.3%) induce immune-mediated dermatological disorders, especially lichen planus. The development of these disorders may reflect a subclinical or covert autoimmune background of patients, as suggested by the presence, although in low titres, of antinuclear antibodies. However, when lichen planus developed, it was mild, did not require the discontinuation of therapy and resolved after alpha-interferon administration had ceased.

Atrophodermia vermiculata.

We present a patient with atrophodermia vermiculata. A family tree study revealed an autosomal mode of inheritance with good penetrance. A slight improvement of the atrophic scars of the disease was noticed after local treatment with tretinoin cream, 0.05 percent, and cryotherapy.

Hidradenitis suppurativa in Crohn's disease. A further support to this association.

A patient with Crohn's disease (CD) subsequently developed the clinical and histological features of hidradenitis suppurative (HS). So far, only five cases with such an association have been reported. Azathioprine (150 mg/d) and methylprednisolone (16 mg/d) for CD combined with isotretinoin (0.7 mg/kg) and periodic administration of antibiotics for HS were used. The treatment was satisfactory, and the patient is now in clinical remission for both diseases.

Anonychia of all toes with absence of phalangeal bones.

A ten year old girl suffered from anonychia of all toes, present from birth. The absence of nails was accompanied by absence of one or two phalangeal bones in toes other than the big toes. Other abnormalities consisted of short toes, incomplete syndactyly of the 2nd and 3rd toes of each foot and transfer of the dermatoglyphics from the plantar to the dorsal surface of the digits. The combined defect of the nails and the phalangeal bones can be explained by the close relationship of the two structures during the morphogenesis of the digits.

Orf. Clinical and epidemiological study.

Twenty eight human cases of orf were studied from clinical and epidemiological points of view. Most of the patients were shepherds who were inoculated from infected animals during all seasons of the year. Typical lesions of different stages of orf were located on the hands, and were accompanied by local symptoms such as pain, pruritus, lymphangitis and adenitis, or less frequently by systemic symptoms such as fever or malaise. Two cases developed erythema multiforme, one developed erysipelas and another a papulovesicular eruption. Tzanck test may contribute to the diagnosis. The course of the disease can not be influenced by antibiotics, and only measures of local hygiene are recommended, except in complicated cases.

Congenital sensory neuropathy with anhidrosis (hereditary sensory neuropathy type IV).

Hereditary sensory neuropathies comprise a group of rare childhood diseases which are classified into four types. We present a Greek boy 11 years old with hereditary sensory neuropathy type IV (congenital sensory neuropathy with anhidrosis) whom we have followed up and studied during the last seven years. Our patient presented for the first time with recurrent hyperthermic episodes without sweating, and lack of pain sensation from the first months of life. Insensitivity to pain and thermal stimuli had resulted in burns on the extremities and self-mutilation of the tongue, lips and fingertips. When he was five and seven years old respectively he had two painless fractures of the ankles which led to insoluble orthopedic problems. He also suffered from mental retardation, which was obvious from his first years of life. Sweat gland investigations showed significant hypohidrosis or anhidrosis although the sweat glands were normal microscopically. Hereditary sensory neuropathy type IV, although rare, is important for dermatologists because it must be differentiated from other anhidrotic syndromes, and in view of the poor prognosis of the condition.

Fixed drug eruption in a mother and her son.

Two cases of fixed drug eruption, occurring in a mother and son, are presented. The eruption in the mother occurred after she ingested dimenhydrinate or acetylsalicylic acid and in the son after ingestion of either of the above drugs or with "junk" food (cheese crisps). Apart from the drugs, anxiety was found to be an essential factor in the manifestation of the mother's disease. A genetic predisposition would seem to link these cases.

Study of the primary crest 'pavement' structure in healthy skin.

The primary crest surface of the healthy skin may have a smooth appearance or form a 'pavement'-like picture because of the presence of circular or polygonal subunits. In this study, the primary crest pavement structure was examined in different sites of healthy skin. The pavement structure was found in 70-100% of the adjacent areas of the palms and soles, and also on the skin of the elbows and knees. This pavement formation is absent on the skin surface of other areas or may be found in a small percentage of 5-20%. It is possible that the pavement structure could represent modified dermatoglyphics in the hairy skin.

Subacute cutaneous lupus erythematosus in Greece. A clinical, serological and genetic study.

We present herein clinical, serological and genetic findings on 27 Greek, subacute cutaneous lupus erythematosus (SCLE) patients. Twenty-three (85 p. 100) presented with a psoriasifom rash in a photosensitive distribution. Two patients (7.5 p. 100) had an annular rash in a polycyclic pattern. Two other patients exhibited both types of lesions. The majority of our patients also had other skin manifestations, including butterfly rash, discoid lesions and maculopapular rash. Systemic manifestations were: arthralgias or arthritis in 50 p. 100, low grade fever in 35 p. 100, central nervous system involvement in 15 p. 100, Sjögren's syndrome in 18 p. 100 and serositis in 8 p. 100. Anti-nuclear antibodies were found in 93 p. 100; antibodies to Ro (SSA) and/or La (SSB) in 70 p. 100. Twenty-one (78 p. 100) satisfied the ARA criteria for systemic lupus erythematosus (SLE). No HLA-DR3 antigen association was found in the 16 patients tested. These findings are somewhat different from those reported previously: a) the frequency of the psoriasiform rash rather than the annular one is the highest in Greek SCLE patients; b) most patients also have other skin manifestations mimicking the full spectrum of SLE with prominent cutaneous lesions; and c) no HLA-DR3 antigen association was found in Greek patients. Environmental, ethnic or genetic factors may be responsible for these differences.

A five year retrospective study on pemphigus and pemphigoid.

In a five year period 73 cases of pemphigus vulgaris (PV) and 94 of bullous pemphigoid (BP) were studied to investigate important parameters for these diseases. From the results it was found that the incidence of PV was higher in women whereas that of BP was almost equal in both sexes. The incidence of PV was highest in the sixth decade but was highest in the eighth decade for BP. Indirect immunofluorescence (IIF) was more sensitive in PV whereas direct immunofluorescence (DIF) was more sensitive in BP. The present study provides a basis for comparison with results of previous or future studies in Greek and other populations.
