Cutaneous reaction to ifosfamide plus mesna treated with desensitization challenge: a case report.

BACKGROUND: Ifosfamide is an alkylating agent used in the treatment of a wide range of tumours. Because of known side effects it is usually administered in combination with mesna, a thiol agent with uroprotective activity, to reduce them and increase the therapeutic dose. The most frequently administered regimens for ifosfamide are fractionated doses for 3 to 5 days, high-dose intravenous bolus, and continuous infusion over 24 to 72 h. Hypersensitivity reactions to ifosfamide plus mesna are not frequently described in the literature. Moreover, no reports exist concerning desensitization for this chemotherapy combination. CASE PRESENTATION: A 47-year-old man with stage IV renal sarcoma was treated with the combination of ifosfamide and mesna every 3 weeks in a 4-consecutive-day infusion protocol. During the second cycle of chemotherapy, he presented acute cutaneous symptoms. A 12-step desensitization protocol was proposed in view of the lack of knowledge of the possible hypersensitivity reactions to this combination of chemotherapy agents, and the multiple difficulties found during the study of the case. CONCLUSIONS: The 12-step desensitization protocol was well tolerated. Therefore, it is an appropriate and safe option in the case of suspected allergy to ifosfamide plus mesna.

Bilateral nasal ala reconstruction of the cocaine-injured nose with 2 free reverse-flow helical rim flaps.

Cocaine abuse can lead to nasal deformity because of local ischemia and subsequent fibrosis. Reconstruction can be challenging. We present a case of bilateral microsurgical nasal ala reconstruction with 2 reverse-flow helical rim flap.

Hemangiopericytoma of the parapharyngeal space: a diagnostic challenge.

Parapharyngeal space tumors are known for having a difficult approach, misleading diagnosis and for representing a treatment challenge. Hemangiopericytomas account for less than 1% of all vascular neoplasms and 3% of all soft tissue sarcomas. Only 14 cases have been reported in the worldwide literature in this location. We present a case of a 44-year-old male who was referred for evaluation. A CT scan and MRI showed a large parapharyngeal mass of a possible salivary gland origin. The patient underwent a lateral cervicotomy associated with a transparotid-transmandibular approach, obtaining a vimentin-positive immunostaining tumor defining the diagnosis. The accurate management and prognosis of this type of neoplasm are provided by the definite diagnosis obtained by a correct histopathologic assessment. A high clinical suspicion is essential.

A questionnaire-based survey in Spain provides relevant information to improve the control of ovine coccidiosis.

Ovine coccidiosis is a widespread intestinal parasitic disease caused by Eimeria spp. Lambs are infected by the ingestion of sporulated oocysts, experiencing diarrhea and low growth rates. Control should be based on measures to reduce infection pressure and stress on the animals as well as on appropriate diagnosis and strategic treatment. To obtain information on how control measures are implemented in the ovine sector in Spain, a questionnaire-based survey was completed in 2022 by 154 veterinarians and 173 farmers working in this sector. Coccidiosis was highlighted as a relevant disease by 34% of the respondents. The period of greatest risk seemed to differ between production systems, being mainly early after weaning (7-15 days after weaning) in meat flocks and feedlots and later (1-2 months after weaning) in dairy flocks. The absence of cleaning and disinfection measures was identified as a risk factor by 51% of the veterinarians, with 22% mentioning overcrowding of animals and 22% indicating that coccidiosis has more incidence in flocks with large number of animals. The use of laboratory diagnosis methods (fecal oocyst count) was unusual in 70 and 84% of the veterinarians and farmers, respectively. Regarding control, dairy flocks usually housed a larger number of animals under intensive conditions, and they implemented more frequently control measures for coccidiosis than meat flocks. Anticoccidial drugs were used in 79% of the flocks, and in 74-82% of them, they were applied based on clinical criteria. Comparing protocols for anticoccidial treatment among different production systems, in meat flocks, anticoccidial drugs were applied more frequently when clinical signs were observed, and coccidiostats were used for less than 28 days compared to dairy flocks. These results highlight the need for improvement in the use of anticoccidial treatments adjusted to the new regulatory framework in the EU, which in turn will rationalize the use of antimicrobial compounds and may help to mitigate the impact of coccidiosis in flocks.

Regional variation in the incidence, general characteristics, and outcomes of prehospital cardiac arrest in Spain: the Out-of-Hospital Spanish Cardiac Arrest Registry. / Variabilidad regional en incidencia, características generales y resultados finales de la parada cardiaca extrahospitalaria en España: Registro OHSCAR.

OBJECTIVES: The incidence and outcomes of care for out-of-hospital cardiac arrest (OHCA) vary greatly from country to country. We aimed to study variation in the incidence, characteristics, and outcomes of care for OHCAs given by Spanish prehospital emergency services. MATERIAL AND METHODS: Descriptive retrospective analysis of data from the Out-of-Hospital Spanish Cardiac Arrest Registry (OHSCAR) from October 2013 to October 2014. Attempts by 19 Spanish emergency services to resuscitate patients were studied. All OHCA cases were reviewed to obtain the following data: incidence, patient and event characteristics, prior emergencies, resuscitation attempts, and the main treatments provided in the hospital. If a patient was admitted, we compared the neurologic status on hospital discharge. RESULTS: Statistically significant differences were detected between emergency services (P .0001) in the incidence of attempted resuscitation and all general characteristics except sex. Hospital treatments and outcomes also differed significantly: pulse had been restored on arrival of 30.5% of patients (range 21.3% to 56.1%, P .001), and 31.8% of admitted patients were discharged in cerebral performance categories 1 or 2 (range 17.2% to 58.3%, P .001). CONCLUSION: Differences in the incidence of resuscitation attempts, key variables, and survival at discharge from the hospital are present in OHCA cases attended by prehospital emergency services in different regions of Spain.

OBJETIVO: Existe gran variabilidad internacional en la incidencia y los resultados en la atención a la parada cardiaca extrahospitalaria (PCRE). El objetivo es conocer si existe variabilidad en la incidencia, características y resultados en supervivencia en la atención a la PCRE por los servicios extrahospitalarios de emergencias (SEM) de España. METODO: Análisis descriptivo, retrospectivo de los datos del registro OHSCAR correspondientes al periodo octubre 2013-octubre 2014, que incluye pacientes atendidos por 19 SEM de España con intento de reanimación. Se recogieron los casos atendidos y variables clave sobre la asistencia a una PCRE: incidencia, características del paciente, del evento, de la actuación previa a los equipos de emergencias (EE), de la reanimación realizada, y de los principales tratamientos hospitalarios. Se comparó la situación neurológica al alta hospitalaria de los casos con ingreso hospitalario. RESULTADOS: La incidencia de casos con intento de reanimación y todas las características generales, salvo la distribución por sexo, presentaron diferencias estadísticamente significativas entre los SEM participantes (p 0,001). Hubo diferencias significativas en los tratamientos hospitalarios recibidos y en los resultados finales, tanto en la proporción de pacientes que llegaron con pulso espontáneo al hospital, 30,5%, rango entre 21,3% y 56,1% (p 0,001), como en el porcentaje de altas hospitalaria con categoría 1 o 2 de la clasificación Cerebral Perfomance Categories (CPC), sobre el total de ingresados, 31,8%, rango entre 17,2% y 58,3% (p 0,001). CONCLUSIONES: Existe una importante variabilidad entre los SEM españoles en la incidencia de casos con intento de reanimación, en todas las variables clave y en la supervivencia al alta hospitalaria de la atención a la PCRE.

Telemedicine influence on the follow-up of type 2 diabetes patients.

OBJECTIVE: This study was designed to evaluate the impact of a teleassistance system on the metabolic control of type 2 diabetes patients. RESEARCH DESIGN AND METHODS: We conducted a 1-year controlled parallel-group trial comparing patients randomized (1) to an intervention group, assigned to a teleassistance system using real-time transmission of blood glucose results, with immediate reply when necessary, and telephone consultations, or (2) to a control group, being regularly followed-up at their healthcare center. Study subjects were type 2 diabetes patients >30 years of age followed in the primary care setting. RESULTS: A total of 328 type 2 diabetes patients were recruited from 35 family practices in the province of Málaga, Spain. There was a reduction in hemoglobin A1c after 12 months from 7.62 +/- 1.60% to 7.40 +/- 1.43% (P = 0.027) in the intervention group and from 7.44 +/- 1.31% to 7.35 +/- 1.38% (P = 0.303) in the control group. The difference in the change between groups was not statistically significant. There was also a significant decrease in systolic and diastolic blood pressure, total cholesterol, low-density lipoprotein cholesterol, and body mass index in the intervention group. In the control group, the only significant decline was in low-density lipoprotein cholesterol. CONCLUSIONS: A teleassistance system using real-time transmission of blood glucose results with an option to make telephone consultations is feasible in the primary care setting as a support tool for family physicians in their follow-up of type 2 diabetes patients.

Uncontrolled donation programs after out-of-hospital cardiac arrest. An estimation of potential donors.

OBJECTIVE: To determine the number of potential deceased organ donors from out-of- hospital cardiac arrest cases (OHCA) attended by public physician-led emergency medical services in Spain, based on data recorded in the nationwide Spanish OHCA Registry (OHSCAR). MATERIAL AND METHODS: We analysed OHSCAR data on deceased OHCA patients in Spain during 13 months (1/10/2013 to 31/10/2014). Variables included age, sex, estimated OHCA time, cardiopulmonary resuscitation (CPR) start time and outcome. Inclusion criteria were: age 16-60 years, witnessed OHCA, no return of spontaneous circulation (ROSC) and time interval <15min between OHCA occurrence and CPR initiation. RESULTS: Of a total 8789 cases, 3290 met the age criteria; of these, CPR was not witnessed in 745 cases. Among the remaining 2545 patients, 141 were included in uncontrolled donation after cardiac death (uDCD) programs, 902 arrived at the hospital with ROSC, 64 arrived with ongoing CPR and 15 cases were lost to follow-up. Of the remaining 1423 without ROSC, CPR initiation time was not recorded in 454 cases and 398 did not meet the time criteria <15min between OHCA and CPR initiation. Finally, 571 met all the criteria and could have been potential donors. There were significant differences in the actual donors percentage from potential donors percentage between provinces with and without donor programs (141/322=43.8% versus 0/390=0%), but there were no differences in ROSC between the two types of provinces (418/1320=31.7% versus 652/1970=33.4%). CONCLUSIONS: Many potential donors are missed in current clinical practice. uDCD programs are few and underused even in a country with high rates of organ transplantation.

Out-of-hospital cardiac arrest (OHCA) attended by mobile emergency teams with a physician on board. Results of the Spanish OHCA Registry (OSHCAR).

Most survival outcomes in out-of-hospital cardiac arrest (OHCA) are provided by emergency medical services (EMS) without a doctor on board. Our objective was to determine such outcomes in a whole country with public physician-led EMS. METHODS: We analyzed data from a nationwide prospective registry of OHCA cases attended by 19 public EMS in Spain, covering the period from 1-October 2013 to 30-October 2014. RESULTS: Advanced life support (ALS) was initiated in 9347 cases (incidence 18.6 cases/105 inhabitants per year). Resuscitation was considered futile in 558 cases (5.9%), and ALS was continued in 8789 cases (94.1%); mean age 63.5±17 years, 72.1% men. Initial rhythm was shockable in 22.1% of cases. Basic life support (BLS) was provided by bystanders in 1602 (24%) cases (635 of them with telephone assistance from the dispatch center). Of 8789 patients receiving ALS, 72.1% men, 2669 (30.4%) patients had return of spontaneous circulation on hospital arrival, 50.6% when the initial rhythm was shockable. Hospital discharge with good neurological status (CPC1-2) was found in 11.1% of the study population and in 27.6% when considering the Utstein comparator group of patients. A total of 216 (2.5%) patients arrived at the hospital with ongoing resuscitation, of whom only one survived with CPC1-2, and 165 (1.9%) patients were included in non-heart-beating donation programs. CONCLUSIONS: In Spain with physician-led EMS, OHCA survival with CPC1-2 reached a reasonable percentage despite only a modest contribution of bystander BLS. Ongoing resuscitation strategy seems to be futile except when considering non-heart beating donation programs.

Promising Technique for Facial Nerve Reconstruction in Extended Parotidectomy.

INTRODUCTION: Malignant tumors of the parotid gland account scarcely for 5% of all head and neck tumors. Most of these neoplasms have a high tendency for recurrence, local infiltration, perineural extension, and metastasis. Although uncommon, these malignant tumors require complex surgical treatment sometimes involving a total parotidectomy including a complete facial nerve resection. Severe functional and aesthetic facial defects are the result of a complete sacrifice or injury to isolated branches becoming an uncomfortable distress for patients and a major challenge for reconstructive surgeons. CASE REPORT: A case of a 54-year-old, systemically healthy male patient with a 4 month complaint of pain and swelling on the right side of the face is presented. The patient reported a rapid increase in the size of the lesion over the past 2 months. Imaging tests and histopathological analysis reported an adenoid cystic carcinoma. A complete parotidectomy was carried out with an intraoperative notice of facial nerve infiltration requiring a second intervention for nerve and defect reconstruction. A free ALT flap with vascularized nerve grafts was the surgical choice. A 6 month follow-up showed partial facial movement recovery and the facial defect mended. CONCLUSION: It is of critical importance to restore function to patients with facial nerve injury. Vascularized nerve grafts, in many clinical and experimental studies, have shown to result in better nerve regeneration than conventional non-vascularized nerve grafts. Nevertheless, there are factors that may affect the degree, speed and regeneration rate regarding the free fasciocutaneous flap. In complex head and neck defects following a total parotidectomy, the extended free fasciocutaneous ALT (anterior-lateral thigh) flap with a vascularized nerve graft is ideally suited for the reconstruction of the injured site. Donor-site morbidity is low and additional surgical time is minimal compared with the time of a single ALT flap transfer.

Laparoscopic approach to right diaphragmatic endometriosis with argon laser: case report.

Diaphragmatic involvement by an endometriotic cyst is a rare entity that may be responsible for chronic thoracic pain. Herein we present a case report of a 6-cm right diaphragmatic endometrioma treated using laparoscopic partial excision and argon laser coagulation of the inner cyst wall. The laparoscopic approach to upper abdomen endometriosis is feasible and safe when accurate evaluation of the case is performed.

Sublingual immunotherapy for hazelnut food allergy: a randomized, double-blind, placebo-controlled study with a standardized hazelnut extract.

BACKGROUND: Food allergy may be life-threatening, and patients affected need to receive accurate diagnoses and treatment. Hazelnut has often been implicated as responsible for allergic reactions, and trace quantities can induce systemic reactions. OBJECTIVE: The aim of this study was to evaluate the efficacy and tolerance of sublingual immunotherapy with a standardized hazelnut extract in patients allergic to hazelnut. METHODS: This was a randomized, double-blind, placebo-controlled study. Inclusion criteria were a history of hazelnut allergy and positive skin prick test and double-blind placebo-controlled food challenge results. Patients were then randomly assigned into 2 treatment groups (hazelnut immunotherapy or placebo). Efficacy was assessed by double-blind, placebo-controlled food challenge after 8 to 12 weeks of treatment. Blood samples were drawn for measurement of specific IgE, IgG(4), and serum cytokines before and after treatment. RESULTS: Twenty-three patients were enrolled and divided into 2 treatment groups. Twenty-two patients reached the planned maximum dose at 4 days. Systemic reactions were observed in only 0.2% of the total doses administered. Mean hazelnut quantity provoking objective symptoms increased from 2.29 g to 11.56 g (P = .02; active group) versus 3.49 g to 4.14 g (placebo; NS). Moreover, almost 50% of patients who underwent active treatment reached the highest dose (20 g), but only 9% in the placebo. Laboratory data showed an increase in IgG(4) and IL-10 levels after immunotherapy in only the active group. CONCLUSION: Our data confirm significant increases in tolerance to hazelnut after sublingual immunotherapy as assessed by double-blind, placebo-controlled food challenge, and good tolerance to this treatment.
