Comprehensive Approach to Lower Blood Pressure (CALM-BP): a randomized controlled trial of a multifactorial lifestyle intervention.

Complementary medicine advocates the use of a multifactorial approach to address the varied aspects of hypertension. The aim of this study was to compare the blood pressure (BP) effect and medication use of a novel Comprehensive Approach to Lowering Measured Blood Pressure (CALM-BP), based on complementary medicine principles, with the standard recommended Dietary Approach to Stop Hypertension (DASH). A total of 113 patients treated with antihypertensive drugs were randomly assigned to either CALM-BP treatment (consisting of rice diet, walks, yoga, relaxation and stress management) or to a DASH+exercise control group (consisting of DASH and walks). Ambulatory 24-h and home BP were monitored over a 16-week programme, followed by 6 months of maintenance period. Medications were reduced if systolic BP dropped below 110 mm Hg accompanied by symptoms. In addition to BP reduction, medications were reduced because of symptomatic hypotension in 70.7% of the CALM-BP group compared with 32.7% in the DASH group, P<0.0001. After 6 months, medication status was not altered in the majority of individuals. Significant reductions in body mass index, cholesterol and improved quality-of-life scores were observed only in the CALM-BP group. Lifestyle and diet modifications based on complementary medicine principles are highly effective with respect to BP control, medication use and cardiovascular risk factors.

Topical capsaicin--a novel and effective treatment for idiopathic intractable pruritus ani: a randomised, placebo controlled, crossover study.

PURPOSE: Pruritus ani is a common and embarrassing proctological condition which can be very difficult to treat. We report the results of a double blind placebo controlled study of treatment with capsaicin. METHODS: Firstly, a pilot open study was carried out on five patients to establish which of two doses was the most acceptable by comparing effectiveness and side effects. Secondly, a double blind, placebo controlled, crossover study of topical capsaicin was performed. This study involved two four week treatment phases separated by a one week washout phase. Forty four patients were randomised to receive locally either active capsaicin (0.006%) or placebo (menthol 1%) ointment over a four week period (22 patients per group). After four weeks of treatment and a one week washout period, the placebo group began to receive capsaicin while the treated group received placebo (menthol 1%) for another four weeks. At the end of the controlled study, responders from both groups continued with capsaicin treatment in an open labelled manner. RESULTS: Thirty one of 44 patients experienced relief during capsaicin treatment periods and did not respond to menthol; all patients not responding to capsaicin also failed on menthol (p<0.0001). In 13 patients, treatment with capsaicin was unsuccessful: eight patients did not respond to capsaicin treatment, one responded equally to capsaicin and placebo, and four others dropped out because of side effects. During the follow up period (mean 10.9 (SD 5.8) months), 29 "responders" needed a mean application of capsaicin every day (1.6 (SD 1.2); range 0.5-7 days) to remain symptom free (or nearly symptom free). CONCLUSION: Capsaicin is a new, safe, and highly effective treatment for severe intractable idiopathic pruritus ani.

Efficacy of prenatal ultrasonography in confirmed club foot.

Club foot can be diagnosed by ultrasound of the fetus in more than 60% of cases. We have correlated the accuracy of the prenatal findings in 281 ultrasound surveys with the physical findings after birth and the subsequent treatment in 147 children who were born with club foot. The earliest week of gestation in which the condition was diagnosed with a high degree of confidence was the 12th and the latest was the 32nd. Not all patients were diagnosed at an early stage. In 29% of fetuses the first ultrasound examination failed to detect the deformity which subsequently became obvious at a later examination. Club foot was diagnosed between 12 and 23 weeks of gestation in 86% of children and between 24 and 32 weeks of gestation in the remaining 14%. Therefore it can be considered to be an early event in gestation (45% identified by the 17th week), a late event (45% detected between 18th and 24th weeks) or a very late event (10% recognised between 25th and 32nd weeks). We cannot exclude, however, the possibility that the late-onset groups may have been diagnosed late because earlier scans were false-negative results. The prenatal ultrasonographic findings were correlated with the physical findings after birth and showed that bilateral involvement was more common than unilateral. There was no significant relationship between the prenatal diagnosis and the postnatal therapeutic approach (i.e., conservative or surgical), or the degree of rigidity of the affected foot.

Bilateral symmetric stress fractures in a toddler.

Stress fractures are a common injury among adolescent athletes and military recruits. The increase in child participation in organized sport activities has contributed to the inclusion of the skeletally immature age group among those who may suffer from this problem. Bilateral simultaneous symmetric tibial stress fractures that are infrequent in older children are even more rare in toddlers. This entity may cause a diagnostic problem as it must be differentiated from infectious disease, acute trauma or even from the result of a battered child.

A simple and efficient surgical technique for subungual exostosis.

Subungual exostosis is a benign osteochondral tumor usually involving the distal phalanx of the great toe. The lesion most frequently occurs in the second and third decades of life and is rare before the age of 10 years. There are few reports of its occurrence in children, and most of them advocate partial or complete nail excision to treat this lesion successfully. We report our experience with six children and adolescents using a simple surgical technique that involves approaching the exostosis under the nail to preserve nail coverage. Rapid recovery and excellent cosmetic appearance were achieved immediately after the operation.

Topical nitrates potentiate the effect of botulinum toxin in the treatment of patients with refractory anal fissure.

BACKGROUND: Anal fissure is perpetuated by high sphincter pressures and secondary local ischaemia. Pharmacological approaches include topical nitrates and botulinum toxin (BT) which act to reduce anal pressure. BT lowers anal pressure by preventing acetylcholine release from nerve terminals while topical nitrates act by donating nitric oxide (NO). The aims of the present study were to compare the therapeutic effect and lowering action on internal anal sphincter pressure of BT injection and local application of isosorbide dinitrate (ID) compared with BT given alone, in patients with chronic anal fissure (CAF) refractory to treatment with ID. METHODS: Thirty consecutive patients with CAF who did not respond to previous topical ID treatments were randomly assigned to receive one of the following treatments: group A, injection of BT (20 U into the internal anal sphincter) and subsequent daily applications of ID (2.5 mg three times daily for three months); and group B, BT injection only (20 U). If at the end of six weeks following BT injection no improvement was seen in group B, ID was added. A series of anal pressure measurements, including resting basal pressure and resting pressure following topical ID (1.25, 2.5, and 3.75 mg), was carried out both before and two weeks after 20 U of BT injection into the internal anal sphincter. At the end of the trial, patients were followed up for an average period of 10 months. FINDINGS: At six weeks the fissure healing rate was significantly higher in group A patients (10/15 (66%)) compared with group B (3/15 (20%)) (p=0.025). At eight and 12 weeks, no significant differences were seen: 11/15 (73%) v 11/15 (73%) and 9/15 (60%) v 10/15 (66%), group A v group B, respectively. Maximum anal resting pressure (MARP) was significantly lower two weeks after BT injection than baseline MARP (90 (4) v 110 (5) mm Hg; p<0.001). A significantly greater reduction in MARP following local application of ID was achieved after BT injection compared with that achieved before BT injection (p=0.037) INTERPRETATION: (1) Combined BT injection and local application of ID in patients with CAF who failed previous treatment with ID was more effective than BT alone. This treatment modality appears to be safe and promising. (2) ID application induced a greater reduction in MARP following BT injection compared with ID application before BT injection. The improved potency of ID on MARP after BT injection suggests a primary cholinergic tonus dominance in some patients and not, as previously claimed, anal sphincter insensitivity to nitrates.

The fibula in congenital pseudoarthrosis of the tibia: the EPOS multicenter study. European Paediatric Orthopaedic Society (EPOS).

Fibular involvement in congenital pseudoarthrosis of the tibia (CPT) can be either a rare isolated pathology or is in association with the tibial changes. Out of 282 patients with CPT who had complete radiographic work-up, 62% (almost two thirds) demonstrated fibular pathology: 36% had true fibular pseudoarthrosis and the rest, i.e., 26% had fibular hypoplasia or dysplastic fibula. Neurofibromatosis was found in 62% of the patients with fibular pathology. The typical radiological features of tibial pseudoarthrosis are often missing in patients with fibular pathology. It is most probably because fibular changes precede the tibial involvement. In 250 patients with tibial surgical treatment, the highest rate of fusion occurred in patients with fibular involvement compared with those with normal fibula.

Treatment of chronic anal fissure with isosorbide dinitrate: long-term results and dose determination.

PURPOSE: Anal fissure is a tear of the anoderm, which eventually can become an ulcer. Chronic anal fissure is perpetuated by contraction of the internal sphincter, believed to reduce perfusion. Nitric oxide is a neurotransmitter mediating vasodilation and internal anal sphincter relaxation. The aim of the present study was to evaluate both the effect and the effective dose regimen of isosorbide dinitrate, a nitric oxide donor, as a treatment for chronic anal fissure. METHODS: Isosorbide dinitrate, Isoket spray (Schwarz-Pharma, Mannheim, Germany), was used to treat 41 patients with chronic anal fissure. Anal manometry was performed in all patients before they entered the study. The treatment program consisted of digital application of isosorbide dinitrate in a dose of 1.25 mg or 2.5 mg three times each day for four weeks. At the end of the trial, patients were followed up for an average time of 11 +/- 1 months. RESULTS: In 34 (83 percent) patients, the fissure healed within one month of treatment (mean, 3 +/- 0.1 weeks). The average time for symptoms to disappear was 6.5 +/- 0.7 days. In six (14.6 percent) patients the anal fissure did not heal even after four weeks of further treatment, and they underwent lateral sphincterotomy. Six patients relapsed during the follow-up period, but responded to another course of treatment. A dose of 2.5 mg of isosorbide dinitrate caused a greater reduction in maximum anal resting pressure than a dose of 1.25 mg. CONCLUSIONS: Topical isosorbide dinitrate is an effective and safe treatment for chronic anal fissure. In our experience the optimal dose regimen is 2.5 mg three times each day.

Cat-scratch disease osteomyelitis from a dog scratch.

Osteomyelitis is a rare manifestation of cat-scratch disease in patients who do not have AIDS. The clinical presentation and non-specific subacute course of the disease make diagnosis difficult. We present a child with osteomyelitis of a metacarpal following a dog scratch. Bartonella henselae was found to be the aetiological agent. The bone healed after treatment with antibiotics. Increased awareness and a comprehensive medical history are needed to identify patients with suspected Bartonella henselae osteomyelitis.

[Laparoscopic colonic resection].

We present our initial experience with laparoscopic colonic resection in 15 patients: adenocarcinoma of the colon, 10 cases, giant villous adenoma (2), arteriovenous malformation (2), and a case of benign stricture. Mean operating time was 190 minutes and there were no intraoperative complications. The margins of resection and number of resected lymph nodes in patients with malignancy were comparable to those in the conventionally operated. Mean postoperative hospital stay was 6.1 days. During a maximum follow-up of 15 months there were no wound or trocar-site recurrences. We conclude that laparoscopic colonic resection is technically feasible and safe. However, its use for treating malignant diseases of the colon needs further study.

Acute upper gastrointestinal bleeding in Jerusalem 1988-91: causes, characteristics and relation to nonsteroidal anti-inflammatory drugs.

We analyzed 321 consecutive episodes of community-based acute upper gastrointestinal bleeding admitted to the Hadassah University Hospital in Jerusalem during 1988-91. Of these 71% were in males aged 56.2 +/- 1.2 years (mean +/- SE) and 29% were in females (67.9 +/- 1.7 years, P < 0.001). The main diagnoses were duodenal ulcer (39.5%), gastric ulcer (16.9%), esophageal varices (10.0%), erosive gastritis (8.2%) and esophagitis (7.5%). The distribution of these diagnoses differed significantly between the genders (P = 0.0003). In males the prevalence of duodenal ulcer and of esophageal varices was higher, and that of gastric ulcer and esophagitis lower, than in females. Gastric ulcer patients were oldest, were the least likely to have received anti-ulcer medications prior to admission, and had the highest levels of urea and the lowest levels of hemoglobin on admission. Use of nonsteroidal anti-inflammatory drugs increased significantly with age and was reported in 35% of the cases (aspirin in doses < 1.0 g/day in 21%, nonsalicylate anti-inflammatory agents in 11%, aspirin plus other anti-inflammatory drugs in 3%). Use of systemic corticosteroids was reported in 4%. The most distinctive features of the population with acute upper gastrointestinal bleeding in the present study compared to other series were the significantly higher proportion of duodenal ulcers and the lower proportion of Mallory-Weiss tears.

Anterior impingement of the femoral head: a late phenomenon of Legg-Calvé-Perthes' disease.

A previously unrecognized late phenomenon of anterior impingement of the femoral head in Legg-Calvé-Perthes' disease is reported in four patients. After an asymptomatic period following reossification of the femoral head, the patients had pain triggered by internal rotation of their hips. Standard roentgenograms did not indicate any cause of the pain. Computed tomography (CT), arthrography, and arthroscopy demonstrated impingement of the anterior aspect of the femoral head against the anterior rim of the acetabulum on internal rotation of the leg. Three hips had femoral head articular surface damage with osteochondral projections at the area of anterior impingement. Arthroscopic debridement and proximal femoral osteotomy was successful in relieving the symptoms.

[Rubber-band ligation of esophageal and cardiac varices].

Esophageal sclerotherapy was the treatment of choice for bleeding esophageal varices in the past decade. It is effective for treating acute variceal bleeding, as well as eradicating esophageal varices for secondary prevention of bleeding. However, in more than 20% of patients sclerotherapy involves complications, some of which are serious. The high complication rate suggested the development of a new method that should be at least as effective and as easy to perform as sclerotherapy, but with fewer complications and side-effects. Endoscopic variceal ligation was developed at the University of Colorado and described in 1986. It is reported to control active variceal bleeding in about 90% of patients, and to eradicate varices in about 80% of surviving patients. Complications are rare. We have adapted the method in our unit and here describe out preliminary experience in 11 patients.

Seasonal fluctuations in acute upper gastrointestinal bleeding: lack of effect of nonsteroidal anti-inflammatory drugs.

The seasonal pattern of community-based acute bleeding from the upper gastrointestinal (UGI) tract was studied prospectively in 1988-1991. Out of 3343 emergency admissions to the Departments of General Surgery, 321 (9.6%) were due to acute UGI bleeding. There was a significant monthly variation in the total number of admissions, as well as in the number of admissions due to acute UGI bleeding (p < 0.0001). However, there was no correlation between the two. Significant seasonal fluctuations were noted both in the absolute number of admissions due to acute UGI bleeding and in the percentage of UGI bleeding admissions of the total number of admissions to the Departments of General Surgery (p = 0.0002). During summer (July through September), the incidence declined significantly to a nadir of 5.5% of total number of admissions in July. The seasonal fluctuation correlated closely with the incidence of duodenal ulcer, but not with that of gastric ulcer. The seasonal pattern was consistent both in patients who had used aspirin or other nonsteroidal anti-inflammatory drugs as well as in those who had not.

Dysplasia epiphysealis hemimelica: diagnosis and treatment.

Clinical features and radiographic findings of eight patients with dysplasia epiphysealis hemimelica are described. In all patients, a single lower extremity was involved. The most common sites of involvement were the distal tibia and the distal femur. Magnetic resonance imaging was beneficial in determining a plane of separation between the accessory ossification center and the normal epiphysis. If the lesion is extraarticular, simple excision of the mass yields favorable results. If the lesion is intraarticular, an osteotomy may be needed to correct an angular deformity. Recurrence of the deformity is common.

Chondrolysis: detection by bone scintigraphy.

Premature closure of the physis of the greater trochanter has been reported to be a predictive sign of chondrolysis in hips with slipped capital femoral epiphysis (SCFE). In the present series, the physis of the greater trochanter showed decreased activity on bone scintigraphy in 16 patients with SCFE and concurrent or developing chondrolysis. In five of these patients, the scintigraphic pattern (decreased activity of the physis of the greater trochanter) preceded radiographic changes of chondrolysis. In 13 patients with SCFE without chondrolysis, the physis of the greater trochanter appeared normal on scintigrams and open on radiographs. Use of scintigraphy in patients with SCFE permitted earlier recognition of chondrolysis, increasing the potential of altering the course of the disease.

[Social and functional results of brachial plexus birth injury].

Long-term results of obstetrical brachial plexus injury were studied. The medical records of 10 females and 9 males (range 16-59 years, mean 27.8) who responded to a questionnaire were reviewed. According to the responses, they all had been leading normal lives, despite various degrees of impairment.

Intraspinal epidermoid tumors in children: problems in recognition and imaging techniques for diagnosis.

Iatrogenic intraspinal epidermoid tumors are very rare. The similarity of the clinical manifestations of the tumor with other childhood problems can pose a problem in diagnosis. In addition, because of the lag in time between the lumbar puncture and the development of a symptomatic tumor, this relationship is overlooked and can cause a delay in diagnosis, as in the present report of four children. Magnetic resonance imaging was found to be superior to myelography in defining the tumor and its relationship to other structures inside the dural sac. All patients underwent surgical excision, with subsequent resolution of symptoms.
