Neonatal mastitis--diagnosis and treatment.

Neonatal mastitis is an uncommon infection. Twenty-one neonates with mastitis were treated at the Bnai Zion Medical Center and Hillel Yaffe Hospital during the years 1985-92. Half of them presented with mastitis, and the other half with breast abscess. The most common pathogen was Staphylococcus aureus, which was isolated in 85% of cases. Antibiotic therapy was the initial treatment in all cases except one, and included i.v. orbenin or augmentin. Puncture of six breast abscesses followed the initial antibiotic course, and another five abscesses were treated surgically by incision and drainage. About half the neonates (10 of 21) recovered after antibiotic treatment alone, indicating that aggressive antibiotic therapy is effective in about 50% of cases and, if started immediately upon diagnosis, no additional surgical treatment is necessary. When an abscess was formed, needle aspiration was as effective as incision and drainage.

Case study: emergence of transient compulsive symptoms during treatment with clothiapine.

Serotonergic dysregulation in obsessive-compulsive disorder has been repeatedly demonstrated. Recent reports on the emergence of obsessive-compulsive symptoms in patients treated with clozapine support a hyposerotonergic hypothesis of obsessive-compulsive disorder. The authors report the emergence of de novo compulsive symptoms in a drug-naive 8-year-old schizophrenic child, shortly after the initiation of treatment with clothiapine. Clothiapine, an atypical antipsychotic agent, shares with clozapine its strong antiserotonergic properties. It seems that antagonistic activity of atypical neuroleptics at postsynaptic serotonergic receptors might be responsible for the development of iatrogenic obsessive-compulsive symptoms.

Sclerosing encapsulating peritonitis--a review.

Sclerosing encapsulating peritonitis (SEP) is a syndrome of multiple causes which, perhaps via a common pathway, affects the small bowel in particular. When persistent intestinal obstruction develops, laparotomy and careful disobstruction of the bowel are indicated. Generally, the prognosis of SEP depends on its cause and the premorbid condition of the individual patient.

The menstrual cycle and acute appendicitis.

OBJECTIVE: To examine the influence of the menstrual cycle on the incidence and presentation of acute appendicitis. DESIGN: Retrospective study. SETTING: University hospital, Israel. SUBJECTS: 144 women of child bearing age operated on for suspected acute appendicitis and subdivided according to the menstrual phase during which they presented. MAIN OUTCOME MEASURES: The final diagnoses, clinical presentation, and laboratory data. RESULTS: There were no significant differences in the incidence of acute, gangrenous, or perforated appendicitis in patients operated on during the various phases of the menstrual cycle. During menstruation, however, a normal appendix not accompanied by other disease was found significantly more often (p = 0.04). Clinical presentation, physical findings, and laboratory results did not vary throughout the menstrual cycle except for the "classic shifting pain" which was significantly more common during the luteal phase. CONCLUSIONS: Acute appendicitis occurs randomly during the various phases of the menstrual cycle. The incidence of operations for uninflamed appendixes may be higher during the menstrual phase. Significantly more negative laparotomies are done during the menstrual phase, which suggests the existence of a functional disorder that mimics acute appendicitis.

Ischemic heart disease precipitated by occult cancer.

The hypothesis was tested that cancer, by virtue of it being a thrombotic diathesis, may enhance ischemic heart disease. Because cancer therapy may precipitate thromboembolism, the authors focused on patients with occult neoplasia before therapy. Occult cancer was defined as a time period of 2 years before a cancer diagnosis was established. Data obtained from the files of patients with the diagnosis of malignant tumors and admitted to a general hospital during a 3-year period were reviewed for coronary risk factors, coronary events, and characteristics of cancer. Indices of coronary instability were studied: the incidence of first coronary events, the incidence of all coronary events, and the coronary events burden. These indices were calculated for 366 patients with cancer (from the Department of Medicine files of 166 consecutive patients with cancer of several primary sites and from the surgical ward files of 100 consecutive patients with colorectal cancer and 100 consecutive patients with cancer of the prostate or bladder) and for 100 patients with benign prostatic hypertrophy. The patients with benign prostatic hypertrophy served as controls. A steep and statistically significant increase in coronary instability indices was observed in all groups of patients with cancer in the 2-year period before cancer diagnosis in comparison with the coronary instability indices of control patients (P less than or equal to 0.05 to 0.0001). Patients with colorectal cancer presented the highest indices in the 2-year period before cancer diagnosis, with unstable ischemic heart disease being reported in 18% and first coronary events in 10%. The coronary events burden was 0.92. The lowest indices among patients with cancer were recorded in those with prostatic and bladder cancer. Unstable ischemic heart disease occurred in 6% and first coronary events in 4%. The coronary events burden was 0.36. The indices were several times lower for control patients than for patients with cancer. Unstable ischemic heart disease occurred in 3% of control patients, and first coronary events in 2%. The coronary events burden was 0.15. Other possible etiologic factors, particularly the known coronary risk factors and anemia, were not statistically related with an increased risk of coronary events in the 2-year period before cancer diagnosis. Based on these epidemiologic data, it appears that there may be an association between occult cancer and coronary events.

Survival of patients with metastatic breast cancer diagnosed between 1955 and 1980.

In order to determine whether current programs for the management of metastatic breast cancer have led to improved patient survival, we determined the median survival times for five-year intervals of 849 patients admitted to the City of Hope National Medical Center with metastatic breast cancer from 1955 to 1980. Survival curves were constructed from the dates of first diagnosis of breast cancer and to the first metastasis for all population subsets and clinical subsets: menopausal status, presence or absence of visceral metastases, length of disease-free interval, and pattern of palliative therapy. In this analysis, the median survival in each successive interval of five years from diagnosis of the primary tumor was 52.1, 45.0, 49.9, 41.1, and 36.0 months, and the survival times from the first metastasis were 31.9, 23.0, 24.2, 23.9, and 18.7 months. Survival times in each of the clinical subsets remained unchanged during the period of observation, regardless of the therapeutic modalities included in the treatment regimens. This study indicates that changes in palliative therapy for metastatic breast cancer during the 25 years of observation have not influenced overall survival. Therefore, it seems appropriate that the therapeutic risk/benefit ratio and impact on quality of life should be reassessed when asymptomatic patients are treated, or when aggressive palliative therapy is used outside a clinical research setting.

[Peripelvic tumors: approach and management].

The peripelvic area consists of the bony pelvis, hip joints and adjacent mesenchymal soft tissues. Malignant lesions in this area present unique diagnostic and therapeutic problems, in particular when tumor removal is involved. Between 1986 and 1988 we treated 7 females and a male, aged 8-75 years, for malignant tumors of this area. Diagnoses (histologic) included 4 cases of malignant fibrous histiocytoma, a malignant schwannoma, a Ewing sarcoma, a chondrosarcoma, and an osteosarcoma. Operations included marginal resection (4 cases), radical resection and reconstruction (2), radical resection (1), and modified hemipelvectomy (2). Adjuvant therapy consisted of radiotherapy in 1 case, chemotherapy in 2, and a combination of both in another 2. A patient who underwent radical resection and reconstruction of his left hemipelvis and hip joint died of local infection that progressed to generalized sepsis 2 months after operation. 2 patients died of recurrent disease, 3 and 30 months, respectively, after primary therapy. 1 died of myocardial infarction 20 months after the first and 3 months after the last of a series of marginal resections. 3 patients are alive and well 3-24 months following their first operation, and the fourth is doing well 24 months following first operation and 23 months after resection of lung metastases. Soft tissue sarcomas and osteosarcomas are the most frequent malignant tumors encountered in the pelvis and peripelvic areas. Their varying grades of malignancy and metastatic potential influence the approach on the one hand, while invalidity and compromised quality of life associated with tumor resection, influence it on the other.(ABSTRACT TRUNCATED AT 250 WORDS)

Joint strength between two layers of different amalgam types condensed successively.

The flexure strength of the joint between layers of different types of amalgam condensed consecutively one on to the other was evaluated in vitro. The data indicated no statistical differences in flexure strength between the combined samples (single composition spherical and lathe-cut eutectic amalgams) and the control (homogeneous lathe-cut eutectic amalgam).

Radiation carcinogenesis in the male breast.

A 53-year-old man developed cystic papillary carcinoma of the breast 30 years after radiotherapy to his chest. This rare type of carcinoma has not been previously reported following irradiation. In contrast to the comprehensive literature on irradiation as an etiological factor in carcinogenesis of the female breast, only 10 cases have been reported in males. The subject is reviewed together with the experience gained on human females and with animals. The carcinogenic characteristics of irradiation are analyzed.

Acute cholecystitis after orthopaedic operations.

When acute cholecystitis follows orthopaedic operations, the disease is frequently obscure and fulminating, with rapid progress to gangrene and perforation of the gallbladder, which may be fatal. Three cases are reported and the literature is reviewed. Various aspects of the disorder are discussed. It is important that orthopaedic surgeons should be aware of the condition in order to be able to make an early diagnosis and so prevent a lethal outcome.

Histoplasmosis of kidneys presenting as chronic recurrent renal disease.

Histoplasmosis is a well-known infectious disease that can sometimes run a mysterious and unexpected course. A case is reported that presented as a chronic renal process, with right pyelocutaneous fistula and prolonged purulent discharge as well as focal calcifications of the left kidney with recurrent stone formation. Histopathologic examination of the right kidney, removed in 1975, showed noncaseating granulomas, but the precise diagnosis was not made until 1983, when histopathologic re-examination followed partial resection of the left kidney, for recurrent stone formation. This article emphasizes the difficulty in diagnosing a noncaseating granulomatous disease in general and histoplasmosis in particular, especially when the urogenital tract is involved, with isolated local manifestations. It underlines the progressive and damaging character of this chronic disease, the variety of its manifestations, and attempts to increase awareness of this potentially treatable disease.
