Anxiety spectrum disorders are common in patients with orthostatic tremor.

BACKGROUND: Orthostatic Tremor (OT) is a rare movement disorder characterized by a sensation of unsteadiness while standing and associated with high frequency tremors. Patients with OT commonly report a fear of falling and significant limitations in everyday activities. The prevalence of psychiatric comorbidities in OT patients has not been well-studied. METHODS: Subjects were evaluated by trained psychiatry researchers using the Mini International Neuropsychiatric Interview (M.I.N.I.). The M.I.N.I is a validated screening tool for psychiatric disorders. A standardized history covering previous psychiatric symptoms and illnesses was also obtained. RESULTS: 29 OT subjects were evaluated. The mean age was 67.7 years with female preponderance (89.3%). The average disease symptom duration was 18.2 years. 58.6% of the subjects had seen a mental health professional during the course of their OT illness. 24.1% of the subjects had a past history of depression, and 10.3% reported a family history of any psychiatric condition. 37.9% of the subjects screened positive for agoraphobia. Two of 29 subjects (6.9%) were classified as having a current major depressive episode and one subject (3.4%) was at risk for suicide. CONCLUSIONS: Psychiatric comorbidities are highly prevalent in OT patients, especially anxiety-spectrum disorders. Further studies are needed to understand if psychiatric disorders appear as a secondary response to the patient's symptoms, or are a primary non-motor manifestation of OT.

Insight and symptom change in schizophrenia and other disorders.

OBJECTIVE: This study sought to evaluate levels of insight and change in insight in subjects with schizophrenia and other major psychiatric disorders. This study also evaluated the relationship of insight to acute psychopathology. METHOD: One-hundred and eighty-seven subjects consecutively admitted to an acute care psychiatric unit and who met DSM-III-R criteria were evaluated by the Insight and Treatment Attitudes Questionnaire and Brief Psychiatric Rating Scale on admission and discharge. Relationships of insight to diagnosis, involuntary commitment status and change in insight were evaluated with analysis of variance and post hoc Tukey's Standardized Range test. Relationships of change in insight and symptoms were evaluated with analysis of covariance (ANCOVA) and correlation. RESULTS: Insight deficits were more prevalent in schizophrenia, a mixed group of other psychosis and bipolar disorder as compared with major depressive and schizoaffective disorder. Committed patients had lower insight. Insight improved across diagnoses during hospital care in both voluntary and committed patients. Significant relationships between improved symptoms and improved insight were obtained in the bipolar, schizophrenia and major depressive groups. CONCLUSION: Insight deficits are prevalent in schizophrenia and bipolar disorder. Many patients show improved insight as their acute symptoms improve. Some aspects of insight are state related during exacerbation of illness in patients with schizophrenia and bipolar disorder.

Complications of voiding cystourethrography in the evaluation of infants with prenatally detected hydronephrosis.

PURPOSE: We determined complications in infants undergoing voiding cystourethrography as part of the evaluation for prenatally detected hydronephrosis. MATERIALS AND METHODS: We retrospectively reviewed the records of infants referred to our institution for the evaluation of prenatal hydronephrosis from 1992 to 1997. Infants with a prenatal history of bilateral hydronephrosis, bladder distention and oligohydramnios, oligohydramnios only or a prenatal abnormality involving any other organ system were excluded from study. Of 206 patients 129 male and 49 female infants underwent postnatal voiding cystourethrography at our institution. Chart review and a telephone interview with the parents were done to assess lower urinary tract infection, pyelonephritis, hospital admission for urosepsis, gross hematuria, urinary retention or skin rash. RESULTS: Postnatal voiding cystourethrography was normal in 138 patients but it diagnosed bilateral vesicoureteral reflux in 15, unilateral vesicoureteral reflux in 20, ureterocele in 4 and refluxing megaureter in 1. Of the 129 male infants evaluated 101 had undergone circumcision as a newborn, 14 were uncircumcised and the circumcision status of 14 was unknown. At voiding cystourethrography suppressive antibiotics were administered to 166 infants, 7 were not on suppressive antibiotics and antibiotic status was unknown in 5. No patient had a lower urinary tract infection, pyelonephritis or urosepsis. In addition, there were no episodes of urinary retention, gross hematuria or skin rash. CONCLUSIONS: While the reported rate of new or recurrent infection associated with voiding cystourethrography is as high as 6%, we did not identify any infectious or other complications in infants undergoing voiding cystourethrography for prenatal hydronephrosis. When properly performed, we believe that voiding cystourethrography is safe and presents little risk in these patients.

Evaluation of the utility of video-urodynamics in children with urinary tract infection and voiding dysfunction.

OBJECTIVE: To assess the use of video-urodynamic studies (VUDS) in children with urinary tract infection (UTI) and symptoms of voiding dysfunction (frequency, urgency, incontinence), to ascertain whether VUDS significantly assists in diagnosis and deciding treatment. PATIENTS AND METHODS: Over a 16-month period, all children seen at our centre with a UTI in conjunction with previous symptoms suggestive of voiding dysfunction underwent free and pressure-flow VUDS. Forty-two children underwent VUDS and 38 (mean age 9 years, range 4-16, 15 male, 23 female) had sufficient information to be included in the study. RESULTS: All children had a prior history of voiding dysfunction (mean 55 months). Only five patients were found to have reflux and three of these had associated detrusor instability. In addition, 24 of 33 patients who did not have reflux had abnormalities on urodynamic study, the most common problem being detrusor instability in 17 of 24 patients. Other abnormalities included sphincter dyssynergia (five patients), poor bladder compliance (two) and hypersensitivity on bladder filling (three). CONCLUSION: VUDS can provide information about the aetiology of UTI and voiding dysfunction in children that cannot be obtained from any other source. The results of VUDS can be used to select specific treatments, to avoid inappropriate therapy and to identify children who may benefit from follow-up studies despite normal findings on voiding cystourethrography. From these results, we believe that VUDS should be considered for children with UTI and voiding dysfunction.

Cystic renal disease and tuberous sclerosis in infants.

We describe 2 infants who presented with autosomal dominant-like polycystic kidney disease. Evaluation revealed that both children had tuberous sclerosis, with resulting cystic kidney disease. This diagnosis should be suspected in infants who present with bilateral, large renal cysts, and no family history of autosomal dominant polycystic kidney disease.

Occult bilateral ectopic vaginal ureters causing urinary incontinence: diagnosis by computed tomography.

Diagnosis of an ectopic, infrasphincteric ureter can be difficult because the renal moiety drained by the ectopic ureter is often small and functions poorly. We present a 6-year-old girl with urinary incontinence caused by bilateral vaginal ectopic ureters that were not seen on excretory urography or renal sonography and were diagnosed only by contrast-enhanced computerized tomography.

A "flipped" kidney in utero in an infant with a double collecting system and a Gartner's duct cyst with a vaginal ectopic ureter.

We report an infant with two unique anatomic abnormalities. A "flipped" kidney in utero is described with the association of a Gartner's duct cyst and a vaginal ectopic ureter with a duplicated collecting system.

Benign fibrous testicular pseudotumors in children.

Benign fibrous pseudotumors of the testicular tunics are rare in children. We report 2 cases of benign fibrous pseudotumors that were managed with gonad sparing surgery. We discuss the etiology, evaluation and treatment of benign fibrous pseudotumors of the testis.

Treatment of paraphimosis using the "puncture" technique.

The puncture technique is a simple method that aids in the manual reduction of the paraphimotic foreskin. We present a case that describes how we are currently using the technique in our pediatric patients.

Acute urinary retention in an infant: an unusual presentation of a paraureteral diverticulum.

We present a case of a male infant with no previous urological symptoms who presented in acute urinary retention caused by compression of the posterior urethra by a paraureteral diverticulum. We discuss the etiology, evaluation and management of bladder outlet obstruction secondary to a paraureteral diverticulum in children.

Training psychiatric residents in the diagnosis and treatment of mental illness in mentally retarded persons.

A serious shortage of psychiatrists trained to care for mentally retarded patients exists. Based on a successful program that has been in place for more than a decade, the authors offer guidelines for training psychiatric residents in the diagnosis and treatment of mental illness in mentally retarded persons. They describe a model curriculum and suggest ways to modify existing four-year curricula. Special diagnostic skills for working with this population, such as posing questions in concrete terms and ruling out the effects of disabilities like seizure disorders, are reviewed. Important treatment issues include knowing the side effects of neuroleptics and understanding the stages through which families and other caregivers pass in accepting a person's mental retardation.

Complications of posterior urethral valve surgery and their prevention.

The treatment of patients with posterior urethral valves has improved dramatically in recent times. Our personal experience with 207 patients with posterior urethral valves between 1957 and 1978 reveals a striking reduction in both mortality and morbidity during the latter decade. We have attempted to identify clearly the incidence, etiologic factors, preventive measures, and surgical treatment of complications arising in these patients. The overall improvement in management is certainly attributable to a growing experience and the constant advancements in the medical and surgical armamentarium. Our next goal at this time is to maximize long-term renal function and growth potential in these patients.
