Alveolar ridge notching as a predictor for secondary bone grafting in incomplete alveolar clefts.

OBJECTIVES: To clarify the need for secondary alveolar bone grafting (ABG) in incomplete alveolar clefts identified clinically from its appearance and test the usefulness of alveolar ridge notching in the edentulous stage as a predictor for ABG. DESIGN: A prospective, cross-sectional study comparing three groups of patients at two stages. PATIENTS: Twenty-four patients with unilateral incomplete cleft of primary palate who underwent either no surgery or cheiloplasty only. METHODS: Cleft severity was assessed at two stages. Initially, the appearance of untreated clefts was assessed before cheiloplasty or at 3 months of age in the patient without cheiloplasty and graded by severity into three groups. Later alveolar bone defects were assessed with computed tomography in the primary or mixed dentition period. A decision regarding the requirement for ABG was then made. Finally, the relationship between untreated clefts and the need for ABG was determined. MAIN OUTCOME MEASURES: Nine (75%) of 12 patients with alveolar ridge notching in the edentulous stage were diagnosed as fulfilling the criteria for ABG. RESULTS: The alveolar bone defects correlated with the severity of untreated cleft conditions (Spearman r = 0.65, p =.002). The need for ABG was greater in patients with alveolar ridge notching, compared with those without notching (9/12 versus 0/12, p =.00034). CONCLUSIONS: Most patients with incomplete alveolar clefts clinically identified in the edentulous stage required ABG, and alveolar ridge notching in the edentulous stage could therefore serve as a predictor for ABG.

Ultrasonography and radiography of the hip in infants.

Both hip joints in 156 children, aged 2 months to 2 years, were examined by ultrasonography (ultrasound) and radiography. Pathologic findings were based on an increased acetabular index, bony defects of the lateral acetabular rim, and lateral and/or proximal displacement of the proximal femur. Each hip was classified as normal, dysplasia, subluxation, or dislocation. The same diagnosis was reached by ultrasound and radiography in 303 of the 312 hips. The accordance was good in normal joints, in subluxation, and in dislocation. However in 7 of the 15 hips with radiographic dysplasia, ultrasound was normal. These patients were not treated, and spontaneous normalization or improvement occurred in all of them. One parameter only, the distance from the lateral margin of the ossification center of the femoral head to Perkins' line, was measured by both ultrasound and radiography; the correlation was high (r = 0.73). We recommend ultrasound as the primary imaging technique when congenital dislocation is suspected clinically.

Three cases of Waardenburg syndrome type 2 in a Korean family.

Waardenburg syndrome (WS) is a rare, autosomal dominant disorder characterized by sensorineural hearing loss, pigmentary disturbances of the skin, hair, and iris, and other developmental defects such as lateral displacement of both medial canthi and lacrimal puncta called dystopia canthorum. While mutations of the PAX3 (paired box) gene have been identified in about 99% of WS type 1 cases, WS type 2 is a heterogeneous group, with about 15% of cases caused by mutations in microphthalmia associated transcription factor (MITF). We have experienced three cases of typical WS type 2 in a Korean family, for whom full ocular examination and genetic studies were performed. The genetic studies revealed no mutation in either PAX3 or MITF genes. The genetic basis, as yet unknown for most cases of WS type 2, might be found with further investigation.

Moyamoya disease initially presenting visual field defect.

Progressive narrowing of distal carotid arteries and the development of compensatory fine networks are the characteristic findings of moyamoya disease. Cerebral infarction in moyamoya disease is due to a decreased blood flow and shows an uneven distribution in the distal bed of the anterior and middle cerebral arteries. The progression of disease in the posterior circulation follows that in the anterior circulation. Posterior circulation symptoms due to cerebral infarction usually occur in the advanced stage of the disease and follow the anterior circulation symptoms. We encountered an unusual case of moyamoya disease which initially presented with a transient visual field defect. One month later our patient developed blindness and her cerebral angiography showed advanced moyamoya disease.

Wound closure using a skin stretching device.

The recent development of an indexed tissue advancement system makes it possible to take advantage of the viscoelastic properties of skin to close large wound deficits in one procedure. A case is presented in which serial excision of a previous split-thickness skin graft and tissue expansion to achieve wound coverage were performed in one sitting to close an 8cm defect on the lateral side of the patient's leg without subsequent wound separation or dehiscence.

Diagnosis and surgical treatment of periapical infection of the third mandibular molar in five horses.

Diagnosis and treatment of periapical infection of the third mandibular molar in 5 horses was assessed. In 4 of 5 horses, there was a recent history of dental work performed. Diagnosis required multiple imaging techniques. Radiography revealed evidence of periapical bone lysis or tooth root lysis of the third mandibular molar in 3 of 5 horses. Sonographic examination was effective in identifying abscesses within the masseter muscle and defects of the lateral cortex of the mandible in 4 of 5 horses. Nuclear scintigraphy was diagnostic in 1 of 2 horses examined. All horses were treated by repulsion of the affected tooth. The surgical approach involved elevating the masseter muscle from the caudal portion of the mandible. This approach provided excellent access to the affected tooth with minimal postoperative complications. All incisions healed with good cosmetic results.

[A surgically treated case of giant pseudoaneurysm arising as a complication following carotid endarterectomy].

We reported a case of giant pseudoaneurysm (PA) originating at the left extracranial internal carotid artery after carotid endarterectomy (CEA). A 60-year-old man underwent CEA for severe stenosis of the left internal carotid artery. A day after the operation, a left cervical painful and pulsatile mass beneath the operative scar was noticed. Soon after that, the patient showed dyspnea, and intratracheal intubation was carried out. 6 days after CEA, a painful swelling reoccurred. A left carotid angiogram visualized a 5 x 5 cm sized PA in the region of the left carotid bifurcation and demonstrated patency of the two major carotid branches. After a balloon catheter had been inserted and inflated at the carotid bifurcation, the patient underwent a second operation. The bleeding from arteriotomy was well controlled by the inflated balloon catheter at the carotid bifurcation. The continuous SURGILENE suture appeared to be disrupted and a saccular PA was found to have arisen from a defect on the lateral surface of the carotid bifurcation. The suture was completely removed and arteriotomy was closed with a continuous SURGILENE suture again and some single sutures were added. A PA arising as a complication following CEA is rare, but the possibility of PA after CEA should be considered in any patient presenting with a painful or/and pulsatile mass in the neck at any time interval following the operation. Angiography at the early post-op stage is necessary to rule out the various complications after CEA. To control the bleeding, the balloon catheter was thought to be very useful.

[Cyclophosphamide-induced renal pelvic tumor--a case report].

We report a case of transitional cell carcinoma in the left renal pelvis, which occurred in a 24-year-old man. He had been treated with cyclophosphamide (CPM) for a period of 27 months for retroperitoneal rhabdomyosarcoma diagnosed at the age of 10. At first 1.2 g CPM had been given twice intravenously for 3 months, followed by oral administration of 41 g CPM for 23 months. Drip infusion pyelography revealed a filling defect in the left renal pelvis. A left renal pelvic tumor was strongly suspected on computerized tomography and magnetic resonance imaging. Left nephroureterectomy was then performed. Histological diagnosis of the left renal pelvic tumor was transitional cell carcinoma, grade 2, pT1N0M0. No recurrence was defected 17 months later. This case seems to be the second case of cyclophosphamide-induced upper urothelial carcinoma reported in Japan.

The hinged-door composite septal flap as structural support and lining of nasal reconstruction by a forehead flap.

In this paper we describe four patients who underwent extensive nasal surgery for carcinoma in the nasal vestibule. Two patients underwent salvage surgery after radiotherapy, whereas the other two patients were treated with primary surgery. In all cases the nasal defect was reconstructed using a composite hinged-door septal flap for structural support and internal lining combined with a paramedian forehead flap which supplied the skin coverage. All patients had a pleasing aesthetic and good functional result. The combination of a paramedian forehead flap with a composite hinged-door septal flap is an excellent reconstruction procedure for defects of the lateral nasal wall and alar region.

ECG-abnormalities in Japanese and Swedish patients with sarcoidosis. A comparison.

BACKGROUND AND AIM OF THE WORK: ECG abnormalities are more common in patients with sarcoidosis than in controls. The incidence of cardiac sarcoid granulomas in the Japanese population has been found to be higher than that seen in Caucasians. We compared the prevalence of ECG abnormalities in Japanese and Swedish patients with sarcoidosis. METHODS: Twelve-lead routine ECG's were compared between consecutive patients (134 Japanese and 149 Swedish) of similar age with histologically verified sarcoidosis or a high clinical probability of the disease and a history of no more than 12 months before the ECG. RESULTS: There was no statistically significant difference in the prevalence of first degree AV block, ST-T-segment abnormalities, right bundle branch block (RBBB) and left anterior block (LAH) in Japanese and Swedish patients. Among the Swedes, the results were compared with those of a smaller group (n = 29) of older patients with a longer disease course. In these few patients LAH and RBBB occurred more frequently than in patients with a recent diagnosis. CONCLUSIONS: ECG abnormalities in patients with sarcoidosis seem to be of similar frequency in Japan and Sweden. ST-T changes and first degree AV block would appear early in the course of the disease, whereas more pronounced conduction defects may appear later.

A multidisciplinary approach to salvage the 'unsalvageable' foot.

Extensive tissue loss in a weight-bearing area of the foot almost invariably heralds limb loss. We report on a 74-year-old man with diabetes mellitus who had an ischaemic foot that was affected by prolonged pressure, which resulted in a necrotic heel. After two sessions of debridement, the calcaneum became exposed. Amputation was initially suggested but was refused by the patient. The foot was subsequently salvaged by staged operations. The first operation was a femoro-anterior tibial bypass using an autogenous saphenous vein to revascularise the foot. This was followed by debridement and attachment of a free subscapular flap to cover the defect 2 weeks later by a plastic surgeon. After 85 days of rehabilitation by physiotherapy and education of foot care by a podiatrist, the patient was discharged home and was able to walk with a walking-stick.

Anomalous origin of the right coronary artery from the left coronary sinus: case report and literature review.

A 41-year-old man with no relevant cardiac history presented for evaluation of episodic syncope. Electrocardiography showed sinus rhythm with right bundle-branch block and Q waves in leads II, III, and aVF. Subsequent exercise treadmill testing and technetium 99m sestamibi study revealed a reversible posterior defect. Coronary angiography later showed a right coronary artery that arose from the left coronary sinus--an anomaly that has been associated with angina, myocardial infarction, and sudden cardiac death. After being informed of the potential risks and options associated with this anomaly, the patient chose long-term beta-blocker medical therapy. At follow-up, this treatment appeared to have resolved his episodic syncope.

Therapeutic contact lens-related bilateral fungal keratitis.

PURPOSE: To describe a rare case of bilateral Candida keratitis after contact lens use following bilateral penetrating keratoplasty (PK). METHODS: A 40-year-old female with a clinical diagnosis of Sjögren's syndrome was being followed for corneal thinning in both eyes. She suffered a spontaneous bilateral perforation and underwent penetrating keratoplasty. Therapeutic contact lenses were prescribed for both eyes owing to persistent epithelial defects. Two months later, a biomicroscopic examination revealed corneal infiltrates. RESULTS: A corneal tissue sample, saline, and contact lens cultures were all positive for Candida albicans. Topical and systemic antifungal therapy successfully cleared the infection in the right eye; however, the left eye underwent another corneal graft surgery. CONCLUSIONS: Infectious fungal keratitis may be a complication of wearing therapeutic contact lenses after PK, in a patient with Sjögren's syndrome. The pre-existing eye disease is an important associated factor in cases of yeast infection; therefore, adequate care of these patients and careful follow-up after PK are indicated as measures to prevent early infections.

[Anomalous systemic arterial supply to normal basal segment of the left lower lobe; report of a case].

A 28-year-old male was referred to our hospital because of hemoptysis. A chest X-ray revealed an increase of vascular marking in the left lower field and a partial defect in the lateral line of the descending thoracic aorta. An aortogram and pulmonary arteriogram showed a large artery arising from the descending thoracic aorta and supplying the left basal segment, which had no normal pulmonary arteries. A bronchoscopy showed no abnormal findings in the bronchial tree. A clinical diagnosis of systemic arterial supply to the basal segment of the left lower lung was made, and a left lower lobectomy and closure of the anomalous systemic artery by video-assisted thoracic surgery (VATS) were successfully performed. Vascular marking of the visceral pleura of left lower basal segment was observed and the anomalous arterial pressure was 84 mmHg, as high as systemic arterial pressure, during the procedure. The histopathological examination revealed normal alveolar structure, and sclerosis and hypertrophy of pulmonary arteries of the lesion (Heath-Edwards V, which means irreversible vascular changes due to pulmonary hypertension). The patient had an uneventful postoperative course and was discharged on postoperative day 8. The VATS procedure is a more useful and less invasive method for cases of systemic arterial supply to the basal segment of the left lower lung than an open thoracotomy.

Bone marrow scan evaluation of arthropathy in sickle cell disorders.

Twelve patients with sickle cell hemoglobinopathies and arthropathy were studied, using technetium Tc 99m sulfur colloid bone marrow scans. Eight of 12 had decreased marrow radionuclide activity adjacent to painful joints, suggestion obliteration of vessels supplying bone marrow. Four patients without marrow defects on scanning had causes other than infarction for their joint symptoms, viz, small fractures, postinfectious synovitis, degenerative arthritis, and osteochondromas. Roentgenograms never showed bony abnormalities in five patients with marrow infarctions, and, in three others, showed defects several months later than did the marrow scans. Bone marrow scans offer a sensitive and early diagnostic aid in sickle cell hemoglobinopathies with arthropathy.

[Use of allogenic cartilage in reconstruction of the middle ear in patients with chronic otitis media].

We have analysed results treatment of 253 patients with chronic otitis media. Our tactic includes operation with application one-momental sanation and reconstruction of a middle ear. Sanational stage was performed in volume atticoantrotomia or radical operation. Reconstruction included reconstruction of a tympanic cavity and retrotympanic space. The shape of a plate was made so that to make a base for neotympanic membrane and to forma a lateral attic wall. Defect of a drum-type membrane restored free flap of a fascia temporal muscle. The mastoid process cavity was filled allogenic cartilage transplants the first variant of reconstruction formed artificial antrum cartilage by fragments and plates. At the second variant was acted similarly, however the artificial cavity wall of the antrum we made soft and mobile from the skin of external acoustical passage and neotympanic fascia flap. In postoperative period the position of a posterior wall of external acoustical passage was formed depending on intratympanic pressure, which depended on a acoustical tube function. Such technique allowed us to reduce formation retraction complications from 15% up to 6.7%.

[Reinjection of 201TL in postinfarct patients so as to improve the demarcation between cicatrix and ischemia].

In patients with earlier myocardial infarction the value of additional imaging after reinjection of 201Tl for better detection of ischemic myocardium was assessed. In 40 patients 40 MBq 201Tl were reinjected 24 h after stress and additional SPECT was performed 1 h later. Quantification of defect sizes showed a further reduction of 4 h redistribution defects by more than 30% in 18 patients. Comparison with clinical, electrocardiographic and scintigraphic parameters showed that none of these was sufficiently accurate for predicting additional thallium uptake after reinjection. In 22 patients with coronary angiography all 11 patients with collateralized occlusions of a coronary artery showed a reduction of the 4 h redistribution defect by > 20%, whereas all patients (5/5) with occlusions without distal collateralization had changes < 20%. This demonstrates that an improved thallium uptake after reinjection is typical of ischemic but vital myocardium.
