Venocutaneous fistula: a central venous catheter--associated complication.

Central venous catheter placement for parenteral feeding, whether short-term as in acute hospital care or long-term as in home total parenteral nutrition (TPN), is a well-established intervention in the patient who cannot eat. Access to the central venous system in the majority of the cases is gained by insertion of the catheter into either the subclavian or jugular vein. Associated with central venous catheters is the possible development of mechanical and septic complications, the incidence of which depends upon the skill, experience, and commitment of both the patient and the nutrition support team. A case report is presented in which a woman developed a venocutaneous fistula due to a chronic indwelling right internal jugular central catheter placed for long-term home nutritional support. The patient's medical history, management of her catheter, and proposed etiology for this problem are discussed, and complications of central access and TPN usage are addressed.

Acoustical control of voice changes after surgery: an exploratory essay.

In this preliminary study, the authors try to validate the use of a quantitative method based upon the use of Long Term Average Spectra (LTAS) and indices of spectral (dis)similarity. The whole spectral information is used and an evolution ratio is introduced. The technique has been tested on 5 patients with organic lesions of the vocal cords (oedema, polypoid degeneration, hyperkeratosis, polyp, pseudocyst). Each patient has been recorded three times: the day before surgery, one and 5 weeks later. The obtained values suggest good correlation between the index variability and the magnitude of clinical change. The values obtained from the quantitative technique turn out to be well correlated with the evolution of the patients' state.

Periareolar Breast Abscess: Redefining the Disease and Its Treatment.

Periareolar breast abscess has been an elusive condition, with much debate about its etiology over the last several decades. Presenting symptoms include nipple discharge, mastalgia, and recurrent abscesses with draining fistulas. Many experts disagree about whether this condition develops when inflammation of the duct leads to dilation or whether it begins with dilation that leads to inflammation. Because the frequency of asymptomatic dilated ducts found incidentally in patients during surgery or upon autopsy exceeds that of patients with symptomatic duct dilation or ectasia, we believe that mechanical obstruction with associated retention of secretions is at the core of this disease process. In this article, we term and characterize mammary-duct-associated inflammatory disease as a 3-phase pathologic process that leads to recurrent nonlactational periareolar breast abscess in nonpuerperal women. Effective treatment of abscesses should be based on the disease's pathogenic process and should include excision of all involved ducts. Treated by this method, patients appear to experience minimal sequelae and low recurrence of abscesses.

Endobronchial actinomycosis.

Endobronchial actinomycosis was found to be the cause of right-sided atelectasis and haemoptysis in a 57 year old man without predisposing conditions. Fibreoptic bronchoscopy revealed occlusion of the intermediate bronchus by yellow-white masses. The diagnosis was confirmed histologically and by positive Actinomyces culture from bioptic material. Prolonged antibiotic treatment resulted in complete recovery, without need for surgical resection.

[The influence of diet on the urinary excretion of total, free and conjugated non-dialysable hydroxyproline in the normal adult (author's transl)].

Having established reference values for the different forms of urinary excretion of hydroxyproline on the basis of the results obtained in 12 normal subjects aged from 20 to 43 years, the authors studied the influence of three diets on the excretion of total, free and conjugated hydroxyproline. Urinary levels of total and peptide dialysable hydroxyprolines were found to be highly sensitive to the dietary collagen content, whilst free hydroxyproline increased only when the dietary collagen intake was very high. Peptide non-dialysable hydroxyproline, corresponding to peptides of molecular weight 6000-8000 was not influenced by diet. The ratio dialysable hydroxyproline/non-dialysable hydroxyproline varied from reference values if the diet was loaded with collagen. Only the ratio free hydroxyproline/non-dialysable hydroxyproline seemed to be independent of diet in the subjects studied.

[Study of Urinary excretion of total, free, and non-dialysable conjugated hydroxyproline in paraplegics].

Eighteen paraplegics with or without neurogenic osteo-arthropathy (POAN) were evaluated for variations in their urinary excretion levels of total (T), and free (L) hydroxyproline and its non-dialysable (ND) and dialysable (D) peptide fractions. Increases in urinary hydroxyproline, moderate rises in free hydroxyproline and more substantial increases in dialysable and non-dialysable peptide fractions could be observed in these patients who all were affected with osteoporosis of disuse. Only variations in dialysable hydroxyproline could be used to differentiate between POAN + and POAN - patients. Of the various ratios which were analyzed (ND/T, L/ND, and D/ND), the D/ND ratio appears to be the most useful for diagnosis and monitoring of patients with POAN.

Laryngeal dysfunction after thyroid surgery: diagnosis, evaluation and treatment.

Because of the close anatomical relationships between thyroid gland and laryngeal nerves, sensory-motor impairment of the laryngeal functions is a well known possible complication of thyroid surgery. Laryngeal nerve paralysis can present with various and often associated symptoms like dysphagia, aspiration, voice alteration or dyspnea. Several examination procedures are mandatory to perform a complete neuro-laryngeal evaluation: rigid and flexible video-stroboscopy will assess the abductor, adductor and tensor functions in breathing, sniffing, talking and eventually singing tasks. Laryngeal electromyography (LEMG), despite its technical difficulties, brings valuable objective and pronostic informations. Aerodynamic assessment of voice production and objective acoustic voice evaluation are important for patients' follow-up, especially for voice professionals like teachers and singers. Treatment of laryngeal sensory-motor nerve paralysis can be conservative, with the help of speech therapy. Early surgical treatment is indicated in cases with severe functional problems like aspiration pneumonia, disabling breathy hypophonia, ineffective cough, disabling dyspnea. Surgical therapy at 6 to 9 months after injury is indicated in patients who demonstrate evidence of denervation or little activity on LEMG and have a poor response to a reasonable trial of speech therapy. Many surgical procedures are available. Depending on the type of neuro-laryngeal deficit, the main and more widely used techniques are: injection laryngoplasty, medialization thyroplasty, arytenoid adduction, arytenoidopexy, crico-thyroid approximation, endoscopic laser cordotomy and re-innervation procedures.

Primary lupus-associated protein-losing enteropathy.

A 79-year-old native American female with a history of diabetes mellitus, but no history of hepatic or renal disease, presented with anasarca and hypoalbuminemia. Laboratory tests for fecal alpha 1-antitrypsin and an indium III-labeled plasma transferrin nuclear scan revealed a protein-losing enteropathy. A serological test was positive for antinuclear antibody in a titer of 1:1250 with a homogeneous pattern. This finding combined with low normal serum complement levels suggested the diagnosis of systemic lupus erythematosus (SLE). This case is unusual in that protein-losing enteropathy was the only presenting symptoms. The late onset of this disease is also unusual.

Acute severe rhabdomyolysis in an human immunodeficiency virus-seropositive patient associated with rising anti-coxsackie B viral titers.

Very recently there have been sporadic reports of polymyositis in patients who are positive for human immunodeficiency virus (HIV). The cause of this condition has not been documented. Recent evidence has been presented which indicates that the Coxsackie B virus may be a causative factor. Presentation is made of a patient, a drug abuser who was found to be HIV-positive with severe polymyositis manifested by generalized muscle weakness and a total serum creatinine kinase that reached the unusually high level of > 600,000 U/L. This patient was found to have a rise in titer of Coxsackie B-4 virus antibodies. He was negative for a variety of possible infectious causes of this condition and was negative for both antinuclear antibodies (ANA) and rheumatoid factor (RF). It is concluded that a polymyositis may indeed be associated with immunosuppressed states and that Coxsackie B-4 virus may be an important causative factor.
