Chronic recurrent multifocal osteomyelitis and psoriasis—A report of a new association and review of related disorders

In summary, we have described two patients with CRMO and psoriasis, and have reviewed the musculoskeletal manifestations associated with pustular eruptions of the palms and soles. In view of the frequent occurrence of PPP in patients with CRMO, we suggest that the occurrence of psoriasis in our two patients is more than coincidence, and that noninfectious, inflammatory lesions of bone may be another musculoskeletal manifestation of psoriasis. This rare association, as well as the association of PPP with disorders associated with new bone formation, may shed new insights on the relatively common finding of periosteal elevation associated with psoriatic arthritis and the occasional severe juxta-articular osteolytic destructive bone lesions seen in psoriatic arthritis.     

Risk analysis in resection of squamous cell carcinoma of the esophagus

A study of risk factors that affect morbidity and mortality in 523 patients with squamous cell cancer of the esophagus who had one-stage resection was undertaken. The 30-day and hospital mortality rates were 5.0% and 15.5%, respectively. Pulmonary complications, malignant cachexia, and surgical complications accounted for 42%, 25%, and 21% of hospital deaths, respectively. Major pulmonary complications occurred in 23% of patients. Multivariate analysis identified six factors that predicted major pulmonary complications: age, mid-arm circumference, percent of predicted FEV₁, abnormal chest radiograph, amount of blood loss, and palliative resection. Three risk groups of pulmonary complications were identified: low, median, and high risk group with complications in 3%, 17%, and 43% of patients, respectively. Significantly, patients with curative resection had a lower hospital mortality rate (9%) than those with palliative resection (20%), p=0.001. Patients with stage I, IIa, or IIb disease had a lower hospital mortality rate (9%) than those with stage III or IV disease (18%), p=0.026. Multivariate analysis identified six factors that predicted hospital death: age, mid-arm circumference, history of smoking, incentive spirometry, number of stairs climbed, and amount of blood loss. Three risk groups of hospital death were identified: low, median, and high risk groups with death in 7%, 30%, and 38%, respectively. Anastomotic leakage rate was 4%. Technical faults were identified in 53% of patients with leakage. Together with other surgical complications, a presumed or apparent technical error was noted in 63% of patients. The identification of high-risk patients and prevention of technical faults can help improve surgical outcome.

Resumen Se emprendió un estudio sobre los factores de riesgo que afectaron la mortalidad en 523 pacientes con carcinoma escamocelular del esófago sometidos a resección en una etapa en nuestra institución.Las tasas de mortalidad a 30 días y de mortalidad hospitalaria fueron 5% y 15%. Las complicaciones pulmonares, caquexia maligna y quirúrgica representaron 42%, 25% y 21% de las muertes hospitalarias, respectivamente. Complicaciones pulmonares mayores fueron registradas en 23% de los pacientes.El análisis multivariado identificó seis factores que predicen complicaciones pulmonares mayores: edad, circunferencia del brazo, porcentaje del FEV1 predecible, radiografía de tórax anormal, pérdida de sangre durante la operación y resección de tipo paliativo. Se identificaron tres grupos de riesgo de desarrollar complicaciones pulmonares: bajo, medio y alto, con tasas de 3%, 17% y 43% de los pacientes, respectivamente. Los pacientes que recibieron resección curative exhibieron una significativamente menor tasa de mortalidad hospitalaria (9%) en comparación con los que recibieron resección paliativa (20%), p=0.001. Los pacientes con enfermedad en estados I, IIa, IIb exhibieron menor mortalidad hospitalaria (9%) en comparación con los estados III o IV (18%), p=0.026. El análisis multivariado identificó seis factores que predicen mortalidad hospitalaria: edad, circunferencia del brazo, historia de tabaquismo, espirometría de incentivo, número de escalones que puede ascender y pérdida de sangre durante la operación. Se identificaron tres grupos de riesgo de mortalidad hospitalaria: bajo, medio y alto, con tasas de 7%, 30% y 38% respectivamente.La tasa de fuga anastomótica fue 4% y se identificaron defectos técnicos en 53% de los pacientes. Junto con otras complicaciones quirúrgicas, se observó un error técnico presumible o aparente en 63% de los pacientes.La identificación de los pacientes de alto riesgo y la prevención de los errores técnicos pueden ayudar a mejorar el pronóstico.

Résumé Dans cette étude, on a étudié les facteurs de risque influençant la morbidité et la mortalité chez 523 patients ayant un cancer épidermoïde de l'oesophage et ayant eu une résection en un seul temps. La mortalité à 30 jours et la mortalité hospitalière ont été respectivement de 5% et de 15.5%. Les complications pulmonaires, la cachexie maligne et les complications chirurgicales ont été responsable respectivement de 42%, 25% et 21% des décès hospitaliers. Une analyse multifactorielle a permis d'identifier six facteurs prédictifs des complications pulmonaires: l'âge, la circonférence brachiale, la prévision du volume expiratoire forcé en une seconde, les anomalies de la radiographie thoracique, la quantité de sang perdu, et le caractère palliatif de la résection. Trois groupes, dont le risque de complications pulmonaires a été classé faible, moyen et élevé, ont été identifiés. Le taux de complications dans ces groupes ont été respectivement de 3%, 17% et 43%. Les patients ayant eu une résection à visée curative avaient une mortalité hospitalière significativement plus basse (9%) comparée à celle des patients ayant eu une résection à visée palliative (20%) (p=0.001). Les patients ayant des maladies de stades I, IIa, IIb avaient une mortalité plus basse (9%) que ceux qui avaient des stades III ou IV (18%), (p=0.026). L'analyse multifactorielle a permis d'identifier six facteurs prédictifs de la mortalité hospitalière: l'âge, la circonférence brachial, des antécédents de consommation excessive du tabac, la spirométrie, le nombre d'escaliers que le patient peut monter, et la quantité de sang perdu. Trois groupes de patients, dont le risque de mortalité hospitalière a été classé faible, moyen, et élevé, ont eu des décès dans respectivement 7%, 30% et 38% des cas. Le taux de fistule a été de 4%. Une faute technique a été identifiée chez 53% des patients ayant eu une fistule. Une faute technique apparente ou présumée a été identifie chez 63% des patients ayant eu soit une fistule soit une complication chirurgicale. L'identification des patients à haut risque et la prévention des fautes techniques peuvent contribuer à améliorer le pronostic après chirurgie.

     

Gold: an old drug still working in refractory pemphigus

BACKGROUND: The mainstay of treatment for pemphigus is systemic corticosteroids. Different adjuvants have been used to reduce side-effects of long-term corticotherapy. Gold is an anti-inflammatory drug used in autoimmune diseases, whose use has waned with the advent of new immunosuppressive agents. OBJECTIVE: To study the outcome of the use of intramuscular gold treatment of pemphigus vulgaris refractory to previous therapies. METHODS: Thirteen patients with pemphigus vulgaris who had failed to respond to several prior therapies were treated with aurothiomalate, as a steroid-sparing agent. Patients were monitored to assess disease activity and gold toxicity. RESULTS: Seven patients achieved complete remission. Four patients were able to taper prednisone doses, although pemphigus flared when prednisone was discontinued or reduced. Toxicity was observed in the other two patients. CONCLUSIONS: In 53.4% of the patients, the use of chrysotherapy resulted in the complete clearing of the disease, discontinuation of all systemic therapies and induced a long-term clinical remission. Prednisone doses were able to be reduced in the remaining 46.6%. Any side-effects were reversible with drug discontinuation. Gold therapy showed efficacy as a secondary line treatment in refractory pemphigus vulgaris.

L-arginine reverses the antinatriuretic effect of cyclosporin in renal transplant patients

BACKGROUND: Cyclosporin has been shown to facilitate renal vasoconstriction and to have an antinatriuretic effect. The existence of an interference of cyclosporin with the vasodilating properties of endothelium mediated by nitric oxide production could mediate these effects. On the other hand, the infusion of the nitric oxide precursor L-arginine has been shown to induce renal vasodilatation and to facilitate natriuresis in normal volunteers. We have investigated the renal effects of the administration of an infusion of L-arginine in renal transplant patients chronically treated with cyclosporin. To facilitate the analysis of the data the effects of the administration of a similar dose of cyclosporin on renal function during the infusion of a vehicle were also investigated during the administration of a vehicle of L-arginine. DESIGN: Ten male renal transplant patients, chronically treated with cyclosporin and with a stable renal function were studied during 2 consecutive days after the administration of the usual morning dose of cyclosporin. The first day they received an intravenous infusion of vehicle and the second the infusion of graded doses of L-arginine (50, 100, 150 mg/kg/h) during 3 consecutive h. RESULTS: The first day, after cyclosporin administration a significant fall (P < 0.01) was observed in natriuresis and kaliuresis in the absence of changes in renal plasma flow and glomerular filtration rate. After the administration of L-arginine significant (P < 0.01) increases of renal plasma flow, glomerular filtration rate, and natriuresis were seen. The increase in blood levels of cyclosporin after its administration did not differ between days 1 and 2. CONCLUSION: These results indicate that L-arginine facilitates renal vasodilatation and natriuresis in renal transplant patients. Furthermore, the observed increase in sodium excretion could indicate that L-arginine counteracts the antinatriuretic effect of cyclosporin.      

Superior gluteal artery steal syndrome

A sacral ulcer is described where ischaemia due to a vascular "steal" syndrome in the gluteal angiotome was the cause of persistent failure of flap reconstruction. Thrombotic obliteration of the abdominal aorta had resulted in the development of collaterals which, paradoxically, deprived the flaps based on standard angiotomes of their major source of blood supply, as they became the major source of perfusion for the legs. Healing of the ulcer was successfully achieved only after aorto-iliac reconstruction. Two other cases of ischaemic sacral ulceration, associated with aortic occlusion, are described.     

An unusual clinical presentation of bilateral schizencephaly

Summary We present a case with a characteristic magnetic resonance image (MRI) of bilateral open-lipped schizencephaly and atypical clinical presentation. The patient is still alive and in good health in her forties, she has never presented seizures, and although the motor dysfunction is well correlated with cerebral lobe involvement, neurobehavioral dysfunction is not proportional to the MR image of the cerebral malformation.

Un cas inhabituel de schizencéphalie bilatérale

Résumé Nous présentons un cas de schizencéphalie bilatérale ouverte caractérisé par une présentation clinique atypique et une imagerie par résonance magnétique nucléaire caractéristique. La patiente est encore vivante, en bonne santé, à plus de 40 ans, elle n'a jamais présenté de crise comitiale et, bien que les troubles moteurs soient bien corrélés aux altérations cérébrales, les troubles neuro-comportementaux ne sont pas proportionnels aux images IRM de cette malformation cérébrale.
