Unilateral diaphragmatic paralysis following bronchial artery embolization for hemoptysis.

Bronchial artery embolization is an effective treatment for patients with hemoptysis. Serious complications are rare, but may occur if the arterial supply to other structures is compromised. We present a case of unilateral diaphragmatic paralysis following bronchial artery embolization in a patient with cystic fibrosis. We believe that the diaphragmatic paralysis was due to the inadvertent obstruction of the left pericardiacophrenic artery during the embolization procedure, with compromise of the phrenic nerve blood supply. This resulted in a significant loss of lung function in our patient, who did not recover despite the subsequent return of diaphragmatic function.

Vocal cord paralysis after surgery for thoracic aortic aneurysm.

OBJECTIVE: To determine the incidence, etiology, prognosis, and treatment of vocal cord paralysis (VCP) after surgery for thoracic aortic aneurysm (TAA). STUDY DESIGN: Retrospective study performed between 1989 and 1995. SETTING: Academic, tertiary care, referral medical center. PATIENTS: Seventy-one TAA patients underwent surgery at the Kameda Medical Center between 1989 and 1995. RESULTS: Sixty-two of 71 patients were examined postoperatively for voice quality. Twenty patients (32%) had hoarseness develop caused by VCP, as confirmed by laryngoscopy. The left recurrent laryngeal nerve had been sacrificed in 1 patient during surgery, but it was preserved in the remaining 19 patients. Unilateral left VCP was noted in 19 patients, and bilateral VCP occurred in 1 patient. The incidence of VCP was higher in those patients who underwent surgery for type I aneurysms (9 of 14 patients, 64%). In 16 of the 19 patients (84%) who received follow-up for > 6 months, vocal cord movement did not return to normal. Surgery to improve voice quality, arytenoid adduction in five patients and intracordal injection in two patients, was performed with success. CONCLUSIONS: Our results indicate that surgery for TAA is associated with a relatively high incidence of VCP. VCP occurred despite preservation of the recurrent laryngeal nerve, and the paralysis did not show a spontaneous recovery even 6 months after surgery.

Prolonged respiratory paralysis in wound botulism.

Two patients had wound botulism with longer duration of respiratory paralysis than previously described. Each sustained extensive trauma to soft tissues and grossly contaminated wounds when thrown from a vehicle in a rural area. Progressive muscular weakness and respiratory distress occurred 8 and 13 days after injury, in the presence of infected wounds and clinical and laboratory findings characteristic of botulism. Spontaneous vital capacity and inspiratory effort served as bedside indicators of ventilatory function throughout 11 weeks of ventilatory support in each case and paralleled other clinical assessments of progress and recovery. Wound botulism may result in neuromuscular paralysis for a prolonged period. These cases illustrate the primary role of scrupulous nursing and respiratory care throughout such a period of ventilatory insufficiency.

Bilateral diaphragm paralysis treated with cuirass ventilation.

The therapeutic effects of cuirass ventilation were studied in two patients with bilateral diaphragm paralysis. Negative inspiratory and positive expiratory pressure applied to the cuirass shell was transmitted to the abdominal and thoracic cavities. Diaphragm excursion was enhanced. Nocturnal cuirass ventilation appears to be an ideal treatment for bilateral diaphragm paralysis.

Benign thyroid hyperplasia presenting as bilateral vocal cord paralysis. Complete remission following surgery.

A 52-year-old woman developed respiratory arrest on two separate occasions that required mechanical ventilation. Fiberoptic bronchoscopy demonstrated bilateral vocal cord paralysis, and a CT scan of the neck demonstrated a right neck mass. On surgical exploration, the mass was found extending from the thyroid gland and was identified as benign thyroid tissue. Thyroid hyperplasia should be considered in the differential diagnosis of bilateral vocal cord paralysis.

Comparison of the incidence of association of periodic paralysis and hyperthyroidism in Japan in 1957 and 1991.

Periodic paralysis has been known to be associated with thyrotoxicosis in Japan. The incidence was 8.6% among male and 0.4% among female thyrotoxic patients according to a survey performed in the three major thyroid clinics in Japan in 1957. To determine the changes in the incidence during the intervening 34 years, the same type of survey was carried out again in 1991 at the same three major thyroid clinics previously involved. The incidence of paralysis in 1991 was 4.3% among male and 0.04% among female thyrotoxic patients, indicating more than a 40% decrease in the incidence. The possible cause of the decrease is related to the changes in food consumption, namely, to the fact that less carbohydrate and more potassium were taken in 1991 than in 1957.

Cat scratch disease presenting with peripheral facial nerve paralysis.

Acquired peripheral facial nerve paralysis is a relatively common disorder that affects both children and adults. The most frequent nontrauma-related etiologies in otherwise neurologically intact patients are idiopathic (Bell's palsy) and infectious, which includes otitis media, herpes zoster, Lyme disease, herpes simplex virus, Epstein-Barr virus, and Mycoplasma pneumoniae. Cat scratch disease (CSD) is typically a subacute, regional lymphadenitis caused by Bartonella henselae that is seen in children and young adults. CSD most often has a benign, self-limited course. However, 11% of CSD patients may present atypically, most commonly with Perinaud's oculoglandular syndrome or acute encephalopathy. We present a child with the first reported case of acute facial nerve paralysis in serologically proven CSD with typical lymphadenitis.

Vocal cord paralysis secondary to impacted esophageal foreign bodies in young children.

Impacted foreign bodies in the esophagus can result in respiratory symptoms including stridor and aphonia. Several mechanisms have been proposed to explain these symptoms, but the possibility of vocal cord paralysis and its cause has not been adequately emphasized. Two cases of young children with esophageal foreign body are described; both presented with respiratory symptoms, 1 with aphonia and the other with stridor. In both cases, the symptoms were secondary to vocal cord paralysis. A possible mechanism of recurrent nerve injury is proposed.

[Peripheral facial paralysis, polyneuritis and chronic Chagas' disease].

The author reports the case of a 42-year-old woman who developed right peripheral facial paralysis and mixed polyneuritis in the course of an undiagnosed Chagas' disease. The clinical diagnosis could be confirmed by serological reactions for Chagas' disease. A likely relationship between chronic Chagas' disease, peripheral facial paralysis and mixed polyneuritis is discussed.

[Indicators of the effectiveness of epidemiological surveillance for acute flaccid paralysis in Brazil from 1990 through 2000].

OBJECTIVES: To describe and compare indicators of the quality of epidemiological surveillance for acute flaccid paralysis (AFP) before Brazil's certification as a poliomyelitis-free area (1990 through 1994) and after that certification (1995 through 2000). METHODS: The following variables were studied: minimum prevalence (reporting annually at least 1 case of AFP per 100 000 individuals younger than 15 years), negative reporting (weekly reporting of the absence of AFP cases by at least 80% of the reporting units in each region), time of investigation (investigating at least 80% of the AFP cases within 48 hours of their being reported), and diagnostic investigation (collection of two stool samples for viral culture in the 2 weeks following the onset of paralysis in 80% or more of the AFP cases). The results were categorized as adequate if they were equal to or higher than the value considered as being effective, or as inadequate if they were below this value. The percentage rate of adequate values was calculated for each of Brazil's 27 federal political divisions (26 states plus the Federal District) in each year, for each of the two periods studied. The final means per period, per federal political division, and per region were also calculated. RESULTS: For Brazil overall, minimum prevalence decreased from 1.3 per 100 000 individuals younger than 15 years in the precertification period to 0.9 per 100 000 in the postcertification period, but the difference was not statistically significant (P > 0.08). While negative reporting was adequate in both periods (87% and 84%, respectively), the percentage rate of effectiveness was 6.6% lower in the postcertification period (P > 0.21). The effectiveness in the time required to investigate AFP cases increased from 60.7% to 71.6% (P > 0.06). The collection of stool samples was inadequate both before and after certification (54% and 52%, respectively). CONCLUSIONS: Despite the absence of indigenous wild virus poliomyelitis cases in Brazil in the postcertification period, the quality of epidemiological surveillance indicators is still less than desirable. This may delay the detection and investigation of AFP cases and compromise the global poliomyelitis eradication effort. New information strategies that are being made available for the health system in Brazil may improve the effectiveness of the national poliomyelitis control program.

Ventricular fibrillation due to severe hypokalemia induced by steroid treatment in a patient with thyrotoxic periodic paralysis.

We report a 25-year-old Japanese man with ventricular fibrillation associated with severe hypokalemia. He developed arm and leg paralysis. He had received 2 g of methylprednisolone because thoracic epidural hematoma had been suspected in another hospital. His serum potassium was 0.8 mEq/l on arrival at our hospital. Half an hour after arrival ventricular fibrillation occurred. Treatment with electric defibrillation 8 times was successful. Afterward Graves' disease was diagnosed, therefore, his clinical symptom was diagnosed as thyrotoxic periodic paralysis. We considered that the unusual condition of hyperthyroid-related hypokalemia worsened by steroid therapy induced the ventricular fibrillation.

Generalized epilepsy in a patient with hypokalemic periodic paralysis and cardiac arrhythmia.

A 17-year-old female who had Hypokalemic periodic paralysis with arrhythmia developed syncopal attacks. Although syncope in this rare disorder has been attributed to ventricular tachycardia or ventricular fibrillation, the clinical manifestation, electroencephalogram, serum electrolytes and blood sugar at the attack, and the results of lumbar puncture indicated that idiopathic generalized epilepsy was the cause of the syncopal attacks in the present case. To our knowledge, this is the first case report of the association of epilepsy with periodic paralysis and arrhythmia in the literature.

A fuzzy-classifier system to distinguish respiratory patterns evolving after diaphragm paralysis in the cat.

We applied the fuzzy "k-nearest neighbor" (k-NN) classifier of the pattern recognition theory to fathom the abnormal way of breathing resulting from diaphragm paralysis and to distinguish the dominant component, tidal or frequency, of the breathing pattern on which ventilatory compensation relies in such a pathological state. We addressed this issue in the experimental model of diaphragm paralysis as a result of bilateral phrenicotomy in anesthetized, spontaneously breathing cats. Of several variables recorded, we selected two features, minute ventilation and arterial CO(2) tension, that were used for the k-NN analysis. The results demonstrate that the ability to maintain ventilation critically depended on the increase in frequency of breathing. Other breathing pattern strategies were ineffective. The k-NN evaluation with the two selected features discerned the prevailing pattern of breathing with sufficient probability. Such an evaluation may be a useful tool in predicting the development of compensatory strategies in disordered patterns of breathing.

Bilateral vocal cord paralysis in newborns with neuraxial malformations--two case reports--.

Two neonates presented with inspiratory stridor due to bilateral vocal cord paralysis associated with occipital encephalocele, Chiari malformation, and hydrocephalus in one patient, and cervical meningomyelocele and Chiari malformation in the other patient. The clinical symptoms dramatically regressed after repair of the encephalocele or meningomyelocele with no requirement for craniovertebral decompressive procedures or shunts in the acute phase. Careful evaluation of neonatal stridor and recognition of vocal cord paralysis are important, as treatment of associated congenital central nervous system anomalies is likely to achieve satisfactory surgical results.

Personality of healthy young adults with sleep paralysis.

Sleep paralysis occurs in normal persons. This phenomenon had been studied psychoanalytically or in terms of the deviation of the victims' personality. This present study aimed to assess the personalities of such persons by using the MMPI and the Maudsley Personality Inventory. The subjects showed a slightly higher mean T score on the MMPI Paranoia Scale than those who did not have this experience. Although this personality difference might be related to the occurrence of the phenomenon, this difference is probably too small to take a major role. It is unlikely that the subjects developed paranoic behavior through their experiences of sleep paralysis, since their experiences were very few. Some of the subjects might have only overestimated their behavior and experiences concerning delusions and hallucinations, with the result that their Paranoia scores were higher and perhaps their kanashibari experiences exaggerated.
