Clinical and pathologic anatomic parameters were studied in 50 patients with maxillonasal dysplasia (Binder's syndrome). The skeletal deformity causing the flat and low-set nose was in typical patients a palpable depression in the anterior nasal floor (fossa prenasalis) and a localized maxillary hypoplasia in the alar base region. Class III malocclusion was found in 54 percent. In 6 percent of the patients a slope (sulcus prenasalis) was found instead of a fossa in the anterior nasal floor, and in one patient a rudimentary fossa was found. Concomitant malformations were noted in 18 percent, and a hereditary connection was seen in 16 percent. The etiology is discussed in relation to the development of the premaxilla and the appearance of a secondary external trabecular network of bone in the canine region. An inhibition of the latter ossification center would explain the localized hypoplasia in the floor and walls of the piriform aperture in maxillonasal dysplasia.

Neutropenia is a life-threatening sequel of hematological disorders and a dominant factor limiting the dosage of cytotoxic chemotherapy. The role of the neutrophil is of such importance in defence against microbial invasion that measures that modify the behaviour of residual hemopoietic tissue to promote a modest increase in neutrophils, can confer considerable benefit by reducing the frequency and severity of infection. Such a change can be mediated in bone marrow depression by diversion of more progeny of immature precursors into the neutrophil series, or by enhancement of the stimulatory drive operating on neutrophil production. The former effect can be achieved by hypertransfusion of red cells to reduce the demand on the limited precursor population for cells of the erythroid series. The latter effect can be achieved by administration of lithium carbonate. Neutropenia caused by autoimmune injury to the neutrophil series can also be successfully modified by measures which suppress the underlying immune dyscrasia or the function of the reticulo-endothelial system. Corticosteroid administration and splenectomy can be helpful in certain specific types of neutropenia. Administration of cyclophosphamide and azathioprine has both mutagenic and marrow suppressive potential, but can induce remissions in severe chronic isolated neutropenia and in systemic lupus erythematosis.

Ninety-three knees with patellar instability were repaired after conservative treatment failed. In 34 there was evidence of tibiofemoral incongruity consisting of an articular depression of the medial femoral condyle by the meniscus. Secondary articular invasion by synovium occurred in 20 knees. Certain clinical phenomena indicate the presence of this impingement lesion: distinct tenderness over the joint line anterior to the medial collateral ligament, pseudo-locking, and increased pain when walking with the tibia rotated externally. These findings are in addition to the usual parapatellar tenderness, apprehension sign, and crepitus encountered in patellar instability. Excessive external tibial rotation is the probable cause of the impingement rather than genu valgum or dysplasia of the vastus medialis. Hypertension may be a factor. The lesion may play a role in the genesis of osteoarthritis subsequent to patellar instability. Transfer of the tibial tubercle medially may be expected to aggravate tibiofemoral incongruity by increasing tibial external rotation. Other procedures are preferred for patellar stabilization.

Comprehensive immune function by integrated score was assessed in 158 operable, 55 inoperable, and 52 metastatic breast cancer patients relative to 107 healthy controls. The score was derived from in vivo response to PPD and DNCB and in vitro lymphocyte stimulation by PPD and PHA. Proportion of E-RFC was significantly lower in patients than in controls but was not found to correlate directly with the above functional criteria. Fifty-one percent of the patients with early, operable tumors were shown to be at least partially immunosuppressed by integrated score achievement vs. 11% of controls. This proportion rises to 68% of inoperable and 89% of metastatic patients. Quantitative analysis by graded response revealed an additional, significant degree of immune impairment in the respective patient groups by all testing parameters. Depression of immune function in operable patients was not related to age nor influenced by surgery. Immunocompetence of patients with mammary dysplasia did not differ from controls. Increasing size of primary tumor (T) was not found to be matched by progressive degree of immunosuppression, excepting that associated with large T4 tumors. Patients with lymph node involvement (N+) were not significantly immunologically inferior to those without (N0) where the larger operable T2-3) tumors are concerned. In the smallest, T1 tumors, nodal involvement (N+) is accompanied by remarkable immunosuppression relative to T1N0 cases. This finding suggests a pre-existing immune defect inherent in T1N+ patients. It supports the hypothesis that the immunosuppression associated with early breast cancer is primary, patient related. Secondary tumor-induced depression of immune response characterizes advanced and metastatic human breast cancer.

Because small flat colorectal neoplastic lesions (i.e., flat adenomas and flat adenocarcinomas) may be as translucent as the surrounding mucosa, they can remain undetected at conventional endoscopy. By combining high-resolution video endoscopy and chromoscopy, we detected 109 colorectal flat neoplastic lesions in 55 of 232 patients studied. Forty-three (78%) of the 55 patients with flat neoplastic lesions were over 60 years of age. No flat neoplastic lesions were seen in patients under 40 years of age. Flat neoplastic lesions were more frequent in men (35%) than in women (15%). Seventy-seven (71%) of the 109 flat neoplastic lesions measured 0.5 cm or less, 23 (21%) between 0.6 and 1.0 cm, and 9 (8%) more than 1.0 cm. Low-grade dysplasia and high-grade dysplasia were found in 94 (86%) and 13 (12%) of the flat neoplastic lesions, respectively. Adenocarcinoma was diagnosed in 3 (3%) flat lesions: 1 (1%) carcinoma originating in a flat adenoma and 2 (2%) adenocarcinomas without recognizable adenomatous elements. No adenocarcinomas were seen in lesions measuring 1.0 cm or less. Fourteen flat neoplastic lesions had a central depression at endoscopy. Flat neoplastic lesions with central depression more frequently showed high-grade dysplasia (43%) than did flat neoplastic lesions without central depression (7%). Central depression in flat neoplastic lesions should be considered a possible endoscopic marker for severe dysplasia. Our results suggest that flat neoplastic lesions occur more frequently than previously reported in Scandinavia. Flat adenomas may play an important role in the histogenesis of colorectal cancer.

We report the clinical and instrumental data, including the endomyocardial biopsy findings, of six young athletes presenting with minor arrhythmias and/or echocardiographic abnormalities. In one of them, a left ventricular dilation with moderate depression of the systolic function had been attributed to an athlete's heart. A diagnosis of arrhythmogenic right ventricular dysplasia had been made in three others, one with right ventricular dilation and apical hypokinesia, and two with ventricular arrhythmias with QRS morphology of left bundle branch block. A myocarditis could be unequivocally established in four athletes (two with and two without fibrosis). In the remaining two, with a clinical history strongly suggesting a previously acute myocarditis, the endomyocardial biopsy specimen revealed a nonspecific fibrosis compatible but not definitely pathognomonic of a healed myocarditis. Our report suggests that a myocarditis may be a cause of minor rhythm disturbances and/or echocardiographic abnormalities in athletes. A prevalent localization of the inflammatory process in the right ventricle with or without the occurrence of ventricular arrhythmias with left bundle branch block morphology can mimic an arrhythmogenic right ventricular dysplasia. An early diagnosis of myocarditis in athletes is useful to avoid the risk of fatal arrhythmias, also considering that rest still keeps on being one of the most effective strategies in myocarditis management.

The case records of 151 dogs diagnosed with congenital heart disease were reviewed retrospectively. The most common defect was aortic stenosis, accounting for 35 per cent of all cases, followed by pulmonic stenosis (20 per cent), ventricular septal defect (12 per cent), patent ductus arteriosus (11 per cent), mitral valve dysplasia (8 per cent), tricuspid valve dysplasia (7 per cent), endocardial fibroelastosis (1.9 per cent) and tetralogy of Fallot (0.6 per cent). Fifty-one breeds were represented, with golden retrievers, German shepherd dogs and boxers predominating. No overall sex predilection was obvious. Seventy-five per cent of the dogs were asymptomatic at presentation. The defects most often associated with presenting symptoms, such as dyspnoea, syncope, ascites, failure to grow and depression, were mitral valve dysplasia, atrial septal defect, tricuspid valve dysplasia and endocardial fibroelastosis. The latter presented with the most severe signs of heart failure. In some cases of aortic stenosis and pulmonic stenosis, where the defect could not be accurately visualised with two-dimensional echocardiography, Doppler echocardiographic examination was needed for definitive diagnosis.

Quantitative criteria of obscure thymic pathology (OTP) are obtained by morphometric study of the thymus of 102 infants with severe infectious-inflammatory processes (IIP). OTP is characterised by depression of epithelial hyperplasia in accidental involution found in 28.4% IIP and is followed by the disturbances mainly in the cell immunity system. This type of thymus pathology is associated in 69% of cases with congenital anomaly of the viscera and skeleton this allowing to regard it as a form of thymus fetal dysplasia.

Flat adenomas are small, barely visible, raised lesions, sometimes with a central depression, which may be markers for a familial risk of cancer. Severe dysplasia is found in nearly half the cases. Carcinomas usually considered as occurring de novo may develop from flat adenomas. Detection of flat adenomas is difficult and substantially increases the duration of colonoscopy; therefore it should be reserved for high risk families. The stains and instruments needed to detect flat adenomas are detailed herein, as well as the excision technique.

Ectodermal dysplasia is a hereditary disease characterized by a congenital dysplasia of one or more ectodermal structures and their accessory appendages. Common manifestations include defective hair follicles and eyebrows, frontal bossing with prominent supraorbital ridges, nasal bridge depression, and protuberant lips. Intraorally, common findings are anodontia or hypodontia, conical teeth, and, consequently, generalized spacing. The patient may suffer from dry skin, hyperthermia, and unexplained high fever as a result of the deficiency of sweat glands. The present review focuses on the clinical manifestations, classifications, and diagnosis of ectodermal dysplasia. A 6-year-old girl, described in the case report, exhibited many of the manifestations of ectodermal dysplasia as well as behavioral problems and a severe gag reflex. The treatment to improve her appearance and oral function included a removable prosthesis, acid-etch-retained indirect resin composite veneers, and a fixed partial denture.
