[Unilateral vocal fold paralysis: quality of voice after speech therapy]

BACKGROUND

To describe demographic factors and voice quality parameters of patients with unilateral vocal fold paralysis (UVFP) after a voice therapy protocol.

METHODS

Forty-seven patients with a diagnosis of UVFP by video-laryngoscopy were included. Voice therapy was applied to all patients during 15 sessions that were structured in three progressive stages. The objective was to train patients in vocal techniques, phonic-breathing coordination,blow control, vocal exercises for glottic closure and vocal setting. Glottal closure, Voice Handicap Index-10 for perception of voice impairment and GRBAS scale were used before and after the speech therapy.

RESULTS

The average age was 51 years (range 20-80), 60%women. Surgery was the most frequent cause (72%), and 40% had a profession related to voice use. Median time from diagnosis to treatment was 5 months (2-12). After voice therapy, 80% had complete glottal closure, previously this had been 34% (p<0.001), the score of VHI-10 decreased from 24.24 to 16.09 points (p<0.001) and GRBAS values improved in all the qualities of voice (p<0.001).Only 8.5% of the patients required surgical intervention after treatment.

CONCLUSIONS

Voice therapy is effective as first line therapy in patients with UVFP, reserving medialization with non-absorbable material or thyroplasty surgery for those with a poor outcome. However, it is necessary to reduce the time it takes the patient to reach the Voice Unit after laryngoscopic diagnosis.

Evolution of diagnostic frequency in schizophrenia spectrum disorders in Acute Psychiatric Unit in Barcelona

Introduction

Several studies have suggested variations in the prevalence of schizophrenia spectrum disorders diagnosis across time. This could be due to a change in diagnostic practice motivated either for changes in DSM criteria as for local culture factors. The aim of this study is to explore the evolution of the schizophrenia spectrum disorders. We hypothesize that we would observe a transference from the schizophrenia diagnosis to psychosis not otherwise specified.

Methods

A retrospective review of all psychiatric discharges in acute unit in the INAD of Parc de Salut Mar of Barcelona, between 2002 and 2014 was performed, relating each discharge to its axis I psychiatric diagnostic. An ANOVA analysis was used to calculate the differences between the months and the frequency of the diagnosis.

Conclusion

We have not been able to observe any transference between diagnoses across years. We observe a decrease of the proportion of schizophrenic spectrum disorders in its prevalence at discharge from 2012 to 2014. The proportion of not otherwise specified psychosis remains quite constant as a third of the schizophrenia diagnoses.

Uncommon isolated distant subcutaneous tissue and skeletal muscle metastasis from oesophageal cancer diagnosed by PET/CT (18)F-FDG

Distant soft-tissue metastases (subcutaneous tissues and skeletal muscle) are extremely rare, particularly in oesophageal carcinoma. The case is described of a patient who was treated for oesophageal adenocarcinoma 2.5 years previously. A PET/CT was performed showing metastatic spread due to a solitary focus of increased tracer uptake corresponding to one subcutaneous node in the upper abdomen. An excisional biopsy showed a metastasis from the carcinoma. Restaging PET/CT (18)F-FDG study was performed 2 year later, demonstrating foci of increased uptake within several muscles as isolated distant haematogenous spread of metastases, histopathologically confirmed. As most of soft-tissue metastases are asymptomatic, the physicians should recommend a histopathological study of focal FDG uptake at subcutaneous tissues and/or skeletal muscles, because they may be the first sign of disease spread, so therapeutic management of these patients could be changed.

[Use of radioguided surgery in the surgical treatment of osteoid osteoma]

OBJECTIVE

Osteoid osteoma is the third most common benign bone tumor and complete surgical resection is definitive treatment. There are a limited number of publications on the use of radioguided surgery in this type of lesion. To assess the utility of radioguided surgery in our environment as a method of surgical treatment of this tumor.

MATERIAL AND METHODS

We retrospectively evaluated 12 patients (2 women and 10 men, age range 9-44 years) with clinical and radiological suspicion of osteoid osteoma. Bone scintigraphy showed foci of pathology uptake compatible with suspected lesion in the femur (4 cases), tibia (3), vertebral column (3), humerus (1) and talus (1). Subsequently patients underwent surgical treatment by radioguided surgery after injection of a dose of (99m)Tc-hydroxy diphosphonate. The nidus was removed using gamma probe and mini gamma camera, considering the technique to be completed when its counts decreased to the levels of the surrounding bone counts.

RESULTS

Lesions were located in all patients (12 of 12), and were confirmed histologically in 8 of them, including an osteoblastoma. The cure rate was 100%, based on the disappearance of pain after a minimum follow-up of 6 months.

CONCLUSION

Use of radioguided surgery in the surgical treatment of osteoid osteoma showed satisfactory results, with 100% efficiency in both lesion location and outcome of treatment and without major postoperative complications.

[SEIP-SERPE-SEOP Consensus document on the treatment of uncomplicated acute osteomyelitis and septic arthritis]

This is a Consensus Document of the Spanish Society of Paediatric Infectious Diseases (Sociedad Española de Infectología Pediatrica), Spanish Society of Paediatric Rheumatology (Sociedad Española de Reumatología Pediátrica) and the Spanish Society of Paediatric Orthopaedics (Sociedad Española de Ortopedia Pediátrica), on the treatment of uncomplicated acute osteomyelitis and septic arthritis. A review is presented on the medical and surgical treatment of acute osteoarticular infection, defined as a process with less than 14 days of symptomatology, uncomplicated and community-acquired. The different possible options are evaluated based on the best available scientific knowledge, and a number of evidence-based recommendations for clinical practice are provided.

[Clinical application of ROLL technique in non-breast diseases. Complementary use after PET-CT study]

OBJECTIVE

The aim of this study was to evaluate the usefulness of ROLL technique (Radioguided Occult Lesion Localization) as a verification method of suspicious lesions not related to breast disease found in PET-CT studies.

MATERIAL AND METHODS

We retrospectively evaluated 9 patients diagnosed of cancer or with suspected tumor disease who showed hypermetabolic lymph nodes in (18)F-FDG PET-CT. Subjects underwent diagnostic testing for evaluation of treatment response in lymphoma (3), suspected recurrence in other tumors (3) or biopsy guide (3). The study group consisted of 4 women and 5 men, age range 25-72 years. ROLL technique was performed in surgically accessible lesions (supraclavicular region, lateral cervical, axillary and inguinal) with an intralesional injection of (99m)Tc-albumin macroaggregates guided by ultrasound the day before surgery. A scintigraphic study confirmed the focal tracer deposit and absence of skin contamination. During surgery, a gamma probe and portable gammacamera were used to locate lymph nodes.

RESULTS

Surgical localization of radiolabeled lymph nodes was achieved in all cases with minimally invasive surgery and few postoperative complications. Histological study resulted in five tumor involvement (3 lymphoma, 1 germ cell tumor and 1 neuroendocrine carcinoma) and confirmed the existence of four false-positives in PET-CT study (1 sarcoidosis and 3 reactive follicular hyperplasia).

CONCLUSION

The ROLL technique proved to be a useful and relatively simple method for the study of no breast lesions suspicious of malignancy in PET-CT study.

Risk of intrauterine growth restriction among HIV-infected pregnant women: a cohort study

The purpose of this investigation was to study the risk of intrauterine growth restriction in human immunodeficiency virus (HIV)-infected women and to describe the associated risk factors. A cohort study was performed among HIV-infected women who delivered in a single tertiary centre in Barcelona, Spain, from January 2006 to December 2011. Consecutive singleton pregnancies delivered beyond 22 weeks of pregnancy were included. Intrauterine growth restriction (IUGR) was defined as a birth weight below the 10th customised centile for gestational age and IUGR babies were compared to non-IUGR newborns. Intrauterine Doppler findings were described among IUGR foetuses. Baseline characteristics, HIV infection data and perinatal outcome were compared between groups. The results were adjusted for potential confounders. A total of 156 singleton pregnancies were included. IUGR occurred in 23.4 % of cases (38/156). In two-thirds of the cases detected before birth, Doppler abnormalities compatible with placental insufficiency were observed. IUGR pregnancies presented a worse perinatal outcome, mainly due to a higher risk of iatrogenic preterm delivery [adjusted odds ratio 6.9, 95 % confidence interval (CI) 1.4-33.5]. IUGR foetuses also had a higher risk of emergent Caesarean section and neonatal intensive care unit admission. No cases of intrauterine foetal death occurred. A high rate of IUGR was observed among HIV pregnancies, and it was associated with adverse perinatal outcomes, mainly iatrogenic preterm and very preterm birth due to placental insufficiency. Our results support that ultrasound detection and follow-up of IUGR foetuses should be part of routine antenatal care in this high-risk population to improve antenatal management.

Risk of clinically significant depression in HIV-infected patients: effect of antiretroviral drugs

OBJECTIVES

We aimed to characterize depression in newly diagnosed HIV-infected patients, to determine the effect of antiretroviral therapy (ART) on its incidence, and to investigate whether efavirenz use was associated with a higher risk, compared with non-efavirenz-containing regimens, in the Spanish CoRIS cohort.

METHODS

CoRIS is a contemporary, multicentre cohort of HIV-infected patients, antiretroviral-naïve at entry, launched in 2004. Poisson regression models were used to investigate demographic, clinical and treatment-related factors associated with a higher incidence of clinically significant depression to October 2010.

RESULTS

In total, 5185 patients (13 089 person-years) participated in the study, of whom 3379 (65.2%) started ART during follow-up. The incidence rates of depression before and after starting ART were 11.68 [95% confidence interval (CI) 9.01-15.15] and 7.06 (95% CI 5.45-9.13) cases per 1000 person-years, respectively. After adjustment, there was an inverse association between the occurrence of depression and the initiation of ART [incidence rate ratio (IRR) 0.53; 95% CI 0.28-0.99], while the likelihood of depression increased in patients of age > 50 years (IRR 1.94; 95% CI 1.21-3.12). Longer exposure to ART was associated with a decreased IRR of depression in unadjusted and adjusted analyses. The IRR for patients receiving < 2, 2-4 and > 4 years of ART was 0.72 (95% CI 0.36-1.44), 0.10 (95% CI 0.04-0.25) and 0.05 (95% CI 0.01-0.17), respectively, compared with ART-naïve patients. This protective effect was also observed when durations of exposure to nonnucleoside reverse transcriptase inhibitor-based regimens and efavirenz-containing regimens were analysed separately.

CONCLUSIONS

The incidence of clinically significant depression was lower among HIV-infected patients on ART. The protective effect of ART was also observed with efavirenz-containing regimens.
