Prevalence and awareness of tinea pedis in Italian sailors.

BACKGROUND: It is difficult to carry out studies on the prevalence of tinea pedis in the community. Some studies are performed on selected groups of subjects, exposed to the same risk factors, i.e. schoolchildren, public bathers, athletes and military men. OBJECTIVE: The aim of this work was to detect in a sample of military men the prevalence of tinea pedis and the awareness of their condition, and to relate the infection to risk factors of the group as well. METHODS: 410 male Italian navy cadets in an Italian navy petty officers school were clinically examined and mycological cultures were performed, employing the skin scrapings obtained from suspected lesions. RESULTS: Dermatophytes were isolated from toe clefts in 10 subjects, giving a point prevalence of 2.4% (95% confidence interval 1.3-4.4%). The isolated dermatophytes were Trichophyton mentagrophytes (70%), Trichophyton rubrum (20%) and Epidermophyton floccosum (10%). None of the subjects was aware of his disease. No significant association was observed between tinea pedis and risk factors (i.e. hyperhidrosis and habits). CONCLUSION: The prevalence in our sample was lower than that observed in previous studies on military men. That can be attributed to the general amelioration of hygienic conditions and strengthening of preventive habits. Therefore the prevalence of tinea pedis in Italian sailors seems to be reduced but still rather relevant. That is important because these subjects are a reservoir of ringworm infection.

Aquagenic syringeal acrokeratoderma (transient reactive papulotranslucent acrokeratoderma).

In 1996, English and McCollough described an unusual entity in 2 sisters characterized by a transient and recurrent keratoderma exclusively on the palms after water exposure. The condition developed 3-5 min after exposure to water and resolved within a short time after drying. This finding was associated with a tightening sensation. Yan et al. coined the term 'aquagenic palmoplantar keratoderma', and the designation 'aquagenic syringeal acrokeratoderma' was suggested by MacCormack et al. Until now, a total of 8 cases have been reported. We documented 2 new cases with acquired aquagenic syringeal acrokeratoderma. A 25-year-old female had observed within the last 3 months a burning sensation on the palms after some minutes of water contact. Physical examination revealed a perfectly normal skin on the palms. Three minutes after water immersion of 20 degrees C, a whitish discoloration appeared on the palms and a thickening of the palmar skin was visible. In addition, the eccrine pores were much more prominent. Few minutes after drying the skin, the situation returned to a normal state. The second patient, a 33-year-old female noticed a painful whitish discoloration of the skin on the palms after a short period of water immersion. Sometimes the white skin could be peeled off. In the last year, hyperhidrosis developed, and a more reddish aspect of the palms appeared. In our office after rinsing the hands with water at room temperature, a whitish discoloration in the center of the palms appeared which was associated with a painful sensation. After drying, the whitish lesions disappeared almost completely within 30 min. Aquagenic palmar keratoderma describes an acquired and transient condition which occurs after brief exposure to water and disappears after drying within minutes to an hour. Only rarely may a slight hyperkeratosis remain for a longer time. The possible pathophysiology and treatment options are discussed.

Mal de Meleda: a new geographical localization in Anatolia.

BACKGROUND: Mal de Meleda (MDM) is an autosomal recessive form of palmoplantar keratoderma first described on the Dalmatian island of Meleda. MDM has been observed in many other countries so that the origin of the MDM gene may be elsewhere than in Meleda. OBJECTIVE: After identification of the first MDM patient during a medical visit, a study was planned to reveal other families with MDM in the Köprüçay region in Anatolia. METHODS: The patient was interviewed with a questionnaire including a pedigree drawing. All the subsequent cases reported to be of MDM were visited for clinical examination and pedigree drawings. RESULTS: Thirty-nine patients, 8 families and 2 additional cases with MDM were identified in a 50-km(2) mountainous region in Köprüçay canyon in Anatolia. The prevalent clinical features were nail involvement (80%), 'glove-and-sock' distribution of the keratoderma (60%), edema on the hands/feet (60%), conical tapering of the fingertips (60%) and hyperhidrosis on the palms and soles (50%). CONCLUSION: To our knowledge, this is the largest series reported. The relationship between the patients in Meleda and those in Anatolia awaits discovery by further researches that will be carried out with the collaboration of dermatology, genetics and medical history departments.

Prevalence and risk factors for superficial fungal infections among Italian Navy Cadets.

BACKGROUND: Limited studies on the prevalence and risk factors for superficial mycoses are available. OBJECTIVE: The aim of this paper was to evaluate the prevalence and risk factors for superficial mycoses (dermatophytes and Candida spp.) in a sample of young Italian people resident at a military school. METHODS: A total of 1,024 young cadets from the Italian Navy Petty Officers School in Taranto, including 975 (95.21%) males and 49 (4.79%) females, mean age 22.5 +/- 3.0 years (range 18-30), were consecutively examined by the same observer. A complete dermatological examination was performed on all the subjects, and skin scrapings for microscopy and fungal culture were obtained from suspected lesions. All the subjects completed a questionnaire providing information on sports practice, swimming-pool attendance, marching, wearing shower sandals, frequent use of 'gummed' shoes, history of severe traumas to the nails, presence of hyperhidrosis and history of superficial mycoses. The affected subjects were also asked if they were aware of their condition. Data were analysed by the Statistical Analysis System, version 8.0. The Fisher exact test and odds ratios were calculated. RESULTS: A total of 33 subjects (3.2%) were found to suffer from a mycologically confirmed fungal infection (3% by dermatophytes and 0.2% by Candida albicans): tinea pedis/Candida intertrigo of the feet was suspected in 126 (12.1%) subjects and confirmed in 30 (2.9%), including 28 cases of tinea pedis and 2 cases of Candida intertrigo; tinea cruris/Candida intertrigo of the groin was suspected in 28 (2.7%) subjects, but confirmed in only 1 case (0.1%); onychomycosis was suspected in 64 (6.1%) subjects and confirmed in 2 cases (0.2%). The organism most frequently responsible in tinea pedis was Trichophyton mentagrophytes var. interdigitale (82.1%). The same species (50%) and T. mentagrophytes var. mentagrophytes (50%) were associated with tinea unguium, Epidermophyton floccosum was the only species detected in tinea cruris. Non-dermatophytic filamentous fungi (Penicillium spp., Fusarium spp., Aspergillus spp. and Paecilomyces spp.), not considered pathogenic, were isolated in 48 samples. None of the risk factors analysed were significantly associated with fungal infection. Only 2 subjects out of the 33 people affected were aware of their condition. They both had tinea pedis. CONCLUSION: The prevalence of mycoses in sailors living in an Italian military school was lower than rates detected in other military populations. This may be due to the cadets' lifestyle and environmental conditions. The most frequent infection was tinea pedis, mainly caused by T. interdigitale. None of the investigated risk factors were significantly associated with the disease, and most of the affected individuals were not aware of their condition.

A new silver-loaded cellulosic fiber with antifungal and antibacterial properties.

The skin is the interface between the body and the environment. Each skin type has a specific skin physiology and is more or less adapted for protection against multiple stress factors. Textiles on the other hand are the tissues with the longest contact with the human skin. They play a critical role especially in skin conditions with an increased rate of bacterial and fungal infections like atopic dermatitis or hyperhidrosis, diabetic patients and aged skin. The present study demonstrates the antifungal and antibacterial effect of Sea Cell(R) Active in an in vitro test system against Candida albicans (DSM 11225), Candida tropicalis (ATCC 1169) and Candida krusei (ATCC 6258). Furthermore, the antibacterial activity of fibers with different amounts of Sea Cell Active fibers could be demonstrated in a dose-dependent manner against Staphylococcus aureus (ATCC 22923) and Escherichia coli (ATCC 35218). Whether this fiber seems to be suited for bioactive textiles in specific anatomical body regions and skin conditions with a susceptibility to fungal and bacterial infections, namely Candida species, S. aureus and E. coli, must be examined by means of further investigations, especially human in vivo tests considering allergic and toxic effects of the fiber.

Recurrent polyradiculoneuropathy with hyperthyroidism.

A 30-year-old woman, who had had two episodes of distal dominant sensorimotor disorders in the extremities, developed again sensorimotor involvement in the distal portion of all limbs. She was also found to have hyperhidrosis, tachycardia and goiter. Neurological and endocrinological examinations led to a diagnosis of coexistence of recurrent polyradiculoneuropathy and hyperthyroidism. Treatment with thiamazole resulted in improvement of the neurological features as well as of hyperthyroidism. The relationship between polyradiculoneuropathy and hyperthyroidism is discussed.

Inflammatory familial palmoplantar keratoderma: Greither's disease?

A case of a familial palmoplantar inflammatory keratoderma with autosomal dominant inheritance is reported. Associated clinical features included vasomotor troubles and hyperhidrosis consistent with a diagnosis of Greither's disease. Light microscopy was nonspecific. Electron microscopy showed aggregated tonofilaments around the nucleus, without true clumps. Desmosomes were numerous and cell-cell junctions showed an imbricated pattern, well demonstrated in the stratum corneum. The diagnosis of Greither's keratoderma is discussed.

Palmoplantar keratoderma with amyotrophy.

Four members of a South African Black family who have palmoplantar keratoderma with amyotrophy are reported. No neuromuscular defects have been found and the muscle thinning appears to result from disuse atrophy. Volar hyperhidrosis, nail abnormalities and in 2 cases knuckle pads, were additional features. The condition appears to be inherited as an autosomal dominant trait. We are not aware of a similar syndrome having been previously reported.

Cutis verticis gyrata with metabolic abnormalities.

An adult Black South African man with forme fruste pachydermoperiostosis is described. The patient had cutis verticis gyrata, hyperhidrosis, sebaceous plugging and an acneform rash. Basal and dynamic endocrine studies revealed that the hypothalamic, pituitary, thyroid, adrenal, gonadal axes and growth hormone secretion were all normal, but urinary excretion of 17-hydroxy-and corticosteroids, and the prolactin response to thyrotropin-releasing hormone were depressed. Urinary levels of asparagine were markedly elevated and serum levels were subnormal indicating a possible renal leak of this amino acid; glutamic acid and ornithine were present in smaller quantities in the urine. All other tests of proximal and distal renal tubular function were normal. There is no evidence from our studies to suggest a hormonal basis for pachydermoperiostosis. The amino aciduria may be a chance association of, or an (additional) occasional manifestation of the syndrome.

Eccrine angiomatous hamartoma: a rare skin lesion with diverse histological features.

A case of painful eccrine angiomatous hamartoma of the wrist in a 10-year-old girl is presented. It was located in the reticular dermis and contained abnormal tubules resembling eccrine secretory coils and thin vascular channels dispersed in the collagenous tissue of the dermis. Some eccrine ducts showed dilatation. The noteworthy features of this case were the absence of hyperhidrosis over the lesion, and the presence of focal neural infiltration by the tubular structures. Electron microscopy showed mostly clear cells and occasional dark cells lining the tubular structures. This case supports the theory of abnormal induction of heterotypic dependency with resultant malformation of adnexal as well as mesenchymal elements.

Volume and cellular content of normal pleural fluid in humans examined by pleural lavage.

Currently, no reliable data are available on the volume or on the cellular content of pleural fluid in normal humans. In analogy with bronchoalveolar lavage (a technique enabling retrieval of small volumes of epithelial lining fluid from the lung), we developed a pleural lavage (PL) technique consisting of injection and retrieval of 150 ml of saline into the right pleural space, performed during a thoracoscopic sympathicolysis procedure in otherwise healthy subjects suffering from essential hyperhidrosis. With urea used as an endogenous marker of dilution, measured mean right-sided pleural fluid volume was 8.4 +/- 4.3 ml. In a subgroup of subjects, we confirmed that right- and left-sided pleural fluid volumes were similar. Expressed per kilogram of body mass, total pleural fluid volume in normal, nonsmoking humans is 0.26 +/- 0.1 ml/kg. Total cell count in the PL fluid of nonsmoking normal subjects yielded a median of 91 x 10(3) white blood cells (WBC) per milliliter of lavage fluid (interquartile range [IR] = 124 x 10(3) cells/ml). Taking into account a measured dilution factor of 18.86, the total WBC count in the original pleural fluid was 1,716 x 10(3) cells/ml. Differential cell counts yielded a predominance of macrophages (median: 75%; IR: 16%) and lymphocytes (median: 23%; IR: 18%). Mesothelial cells (median: 1%; IR: 2%), neutrophils (median: 0%; IR: 1%), and eosinophils (median: 0%; IR: 0%) were only marginally present. There were no significant differences between males and females or between right- and left-sided pleural fluid in total and differential cell counts. In contrast, in smokers a small but statistically significant increase in pleural fluid neutrophils (median: 1%; IR: 2%; p < 0.015) was observed. In conclusion, PL performed during thoracoscopy for sympathicolysis allowed for the first time determination of the volume and of the total and differential cell contents of the pleural fluid present in normal human pleura.

Cardiovascular collapse caused by carbon dioxide insufflation during one-lung anaesthesia for thoracoscopic dorsal sympathectomy.

Carbon dioxide insufflation into the pleural space during one-lung anaesthesia for thoracoscopic surgery is used in some centres to improve surgical access, even though this practice has been associated with well-described cardiovascular compromise. The present report is of a 35-year-old woman undergoing thoracoscopic left dorsal sympathectomy for hyperhidrosis. During one-lung anaesthesia the insufflation of carbon dioxide into the non-ventilated hemithorax for approximately 60 seconds, using a pressure-limited gas inflow, was accompanied by profound bradycardia and hypotension that resolved promptly with the release of the gas. Possible mechanisms for the cardiovascular collapse are discussed, and the role of carbon dioxide insufflation as a means of expediting lung collapse for procedures performed using single-lung ventilation is questioned.

Advanced techniques in medical thoracoscopy.

For expert pulmonologists, advanced procedures in medical thoracoscopy are the nonroutine and more complex applications of the method. The main current indications are the treatment of infected pleural space, forceps lung biopsy and sympathectomy. In parapneumonic effusions and empyema, medical thoracoscopy is as a drainage procedure, intermediate between tube thoracostomy and video-assisted thoracoscopic surgery (VATS), which is efficient, significantly lower in cost and avoids surgical thoracoscopy under general anaesthesia. It is essential that it is performed early in the course of the disease and is particularly advisable for frail patients at high surgical risk. The efficacy of forceps lung biopsy has been demonstrated in diffuse lung diseases, whereas results in localised lung diseases and chest-wall lesions have been less positive. However, VATS is currently the preferred approach for these indications. The technique still maintains its efficacy for visceral pleura and peripheral lung biopsy, in particular in the presence of pleural effusion and lung disorders. At the present time, thoracoscopic sympathectomy is minimally invasive and is an accepted intervention for patients with a variety of autonomous nervous system disturbances. Essential hyperhidrosis patients, and well-selected patients with other disorders, can be helped with this procedure, which can also be performed by interventional pulmonologists.

Characterisation of pleural inflammation occurring after primary spontaneous pneumothorax.

The aim of this study was to examine the inflammatory reaction occurring in the pleural space of patients suffering from primary spontaneous pneumothorax (PSP) using pleural lavage, which was performed in patients with PSP and in healthy control subjects (essential hyperhidrosis patients undergoing thoracoscopy for sympathicolysis treatment). Cellular and solute composition of lavage fluid, peripheral blood and parietal pleural biopsies were analysed. PSP lavage fluid showed an increase in all differentiated leucocytes, but most strikingly eosinophils and neutrophils. In the blood of patients with PSP, the total number of leucocytes and the absolute number of eosinophils, neutrophils and monocytes were also significantly increased. The time in which air was present in the pleural space was positively correlated with the increase of eosinophils in lavage fluid, parietal pleura and blood. Eosinophilic cationic protein was elevated after PSP and strongly correlated with the absolute number of lavage eosinophils. Chemo and cytokine analysis in lavage fluid showed differences in concentrations of interleukin (IL)-5, IL-6, IL-8, IL-12p40, tumour necrosis factor-alpha and RANTES, but not of eotaxin. Surprisingly, high levels of lipopolysaccharide binding protein were also measured. Primary spontaneous pnumothorax is associated with a substantial pleural inflammatory reaction. The authors hypothesise that mechanical stretch factors, lipopolysaccharide binding protein/lipopolysaccharide complexes or other environmental components trigger pleural inflammation after primary spontaneous pnumothorax.

Case report: acute unintentional carbachol intoxication.

INTRODUCTION: Intoxications with carbachol, a muscarinic cholinergic receptor agonist are rare. We report an interesting case investigating a (near) fatal poisoning. METHODS: The son of an 84-year-old male discovered a newspaper report stating clinical success with plant extracts in Alzheimer's disease. The mode of action was said to be comparable to that of the synthetic compound 'carbamylcholin'; that is, carbachol. He bought 25 g of carbachol as pure substance in a pharmacy, and the father was administered 400 to 500 mg. Carbachol concentrations in serum and urine on day 1 and 2 of hospital admission were analysed by HPLC-mass spectrometry. RESULTS: Minutes after oral administration, the patient developed nausea, sweating and hypotension, and finally collapsed. Bradycardia, cholinergic symptoms and asystole occurred. Initial cardiopulmonary resuscitation and immediate treatment with adrenaline (epinephrine), atropine and furosemide was successful. On hospital admission, blood pressure of the intubated, bradyarrhythmic patient was 100/65 mmHg. Further signs were hyperhidrosis, hypersalivation, bronchorrhoea, and severe miosis; the electrocardiographic finding was atrio-ventricular dissociation. High doses of atropine (up to 50 mg per 24 hours), adrenaline and dopamine were necessary. The patient was extubated 1 week later. However, increased dyspnoea and bronchospasm necessitated reintubation. Respiratory insufficiency was further worsened by Proteus mirabilis infection and severe bronchoconstriction. One week later, the patient was again extubated and 3 days later was transferred to a peripheral ward. On the next day he died, probably as a result of heart failure. Serum samples from the first and second days contained 3.6 and 1.9 mg/l carbachol, respectively. The corresponding urine concentrations amounted to 374 and 554 mg/l. CONCLUSION: This case started with a media report in a popular newspaper, initiated by published, peer-reviewed research on herbals, and involved human failure in a case history, medical examination and clinical treatment. For the first time, an analytical method for the determination of carbachol in plasma and urine has been developed. The analysed carbachol concentration exceeded the supposed serum level resulting from a therapeutic dose by a factor of 130 to 260. Especially in old patients, intensivists should consider intoxications (with cholinergics) as a cause of acute cardiovascular failure.

Growth hormone deficiency and hyperthermia during exercise: a controlled study of sixteen GH-deficient patients.

Sweat secretion is often disturbed in patients with GH secretory disorders. Hyperhidrosis is a classic feature of acromegaly, and it has recently been shown that GH-deficient patients exhibit decreased sweating capacity after pilocarpine stimulation of the skin. Thus, patients with GH-deficiency may be at risk for developing hyperthermia. To pursue this, we performed a controlled study on sweating and body temperature regulation during exercise in the heat in 16 GH-treated GH-deficient patients with normalized insulin-like growth factor-I and insulin-like growth factor/binding protein-3 serum levels [11 with multiple pituitary deficiency (MPD) and 5 with isolated GH deficiency] and in 10 healthy subjects as controls (CTs). Each subject exercised on a bicycle ergometer for 60 min at a workload corresponding to 45% of their individual maximal oxygen consumption (VO2max), in a room maintained at 35 C. GH serum concentrations increased significantly after approximately 10 min of exercise in the CTs (P < 0.001) but remained low in the patients. Body heat storage was significantly higher in the patients compared with the CTs [89 (SE +/- 10) watts (MPD) vs. 37 (SE +/- 8) watts (CTs), P < 0.001]. Consequently, the core temperatures of the patients increased significantly after exercise compared with those of the CTs [38.3 C (0.10 C) (MPD) and 38.1 C (0.06 C) (isolated GH deficiency) vs. 37.5 C (0.2 C) (CTs) (P < 0.004)]. Skin temperature increased significantly during exercise in the patients but remained unaltered in the CTs. Sweat secretion rates, as determined by the pilocarpine method, were significantly lower in the MPD patients [77 (SE +/- 10) mg/30 min] than in the CTs [115 (SE +/- 7) mg/30 min] (P < 0.005). Total body sweating was lower in the patients than in the CTs, although the difference did not reach statistical significance. Significantly reduced estimated evaporative heat loss was demonstrated in the patients compared with the CTs (P < 0.001). In conclusion, 1) decreased sweating, decreased sensitivity of the sweat gland, and impaired thermoregulation are part of the adult GH-deficiency syndrome, and 2) GH-deficient patients are at risk for developing hyperthermia during physical activity in hot environments.

Long-acting lanreotide induces clinical and biochemical remission of acromegaly caused by disseminated growth hormone-releasing hormone-secreting carcinoid.

Ectopic GHRH-secreting tumors, such as carcinoid, rarely cause acromegaly. As protracted exposure to high levels of GH is associated with considerable morbidity and mortality, these patients require early and effective medical therapy to control hormonal hypersecretion. We employed a prolonged release somatostatin analog, lanreotide, to treat a patient with disseminated GHRH-producing carcinoid. Before treatment, the patient had a biochemical profile characteristic of active acromegaly. Plasma GHRH levels were markedly elevated (200-fold), and urinary 5-hydroxyindolacetic acid (5-HIAA) levels were increased (4-fold). Magnetic resonance imaging revealed a large asymmetrical pituitary mass consistent with somatotroph hyperplasia. Somatostatin receptor scintigraphy revealed multiple bony and soft tissue lesions as well as striking pituitary uptake. Lanreotide (30 mg) was administered weekly by im injection for 12 weeks. Rapid and sustained symptomatic clinical improvement with diminished soft tissue swelling and hyperhidrosis was observed. GHRH levels decreased by 70%; glucose-suppressed GH and insulin-like growth factor I levels were reduced by 90% and 75%, respectively, to near normal values; urinary 5-HIAA levels normalized; and the pituitary mass remained unchanged. Unfortunately, the patient died due to complications of osteogenic sarcoma. In conclusion, prolonged release lanreotide induced clinical and biochemical remission in this patient with diffusely metastatic GHRH-producing carcinoid. This long-acting drug thus offers an effective, well tolerated, and convenient medical therapy for control of hormonal hypersecretion induced by excess GHRH.

Fatal familial insomnia: clinical and pathologic study of five new cases.

In 1986, we reported two anatomoclinical observations of a familial condition that we called "fatal familial insomnia" (FFI). We now present the pedigree as well as the clinical and neuropathologic findings in five new subjects. The pedigree includes 288 members from six generations. Men and women are affected in a pattern consistent with an autosomal dominant inheritance. The age of onset of the disease varies between 37 and 61 years; the course averages 13 months with a range of 7 to 25 months. Progressive insomnia (polygraphically proven in two cases); autonomic disturbances including hyperhidrosis, hyperthermia, tachycardia, and hypertension; and motor abnormalities including ataxia, myoclonus, and pyramidal dysfunction, were present in every case, but with variable severity and time of presentation. Sleep and autonomic disorders were the earliest signs in two subjects, motor abnormalities were dominant in one, and others had intermediate clinical patterns. Pathologically, all the cases had severe atrophy of the anterior ventral and mediodorsal thalamic nuclei. Other thalamic nuclei were less severely and inconsistently affected. In addition, most of the cases had gliosis of the cerebral cortex, a moderate degree of cerebellar atrophy with "torpedoes," and severe atrophy of the inferior olivary nuclei. One case also showed spongy degeneration of the cerebral cortex. We conclude that all the lesions were primary, and that FFI is a multisystem disease in which the different structures are primarily affected with different severity. The insomnia appears to correlate best with the major thalamic pathology. The possibility that FFI belongs to the group identified as prion diseases or diseases transmitted by unconventional agents is examined.
