Radiographic features of periapical cysts and granulomas.
Many studies have been reported on radiographic lesion sizes of periapical lesions. However no studies have been reported on prevalences of subjective radiographic features in these lesions except for the early assumption that a periapical cyst usually exhibit a radiopaque cortex. This study is conducted to evaluate the prevalences of several subjective radiographic features of periapical cysts and granulomas in the hope to identify features that maybe suggestive of either diagnosis. The results showed that a regular (circular or semi-circular) radiographic outline is likely to be a periapical cyst while an irregular radiographic outline is not indicative of either a cyst or a granuloma. The association between the regular/irregular radiographic outline and the type of periapical lesion was found to be statistically significant (p less than 0.001). The associations of two other radiographic features and the type of periapical lesion were found to be just statistically significant (p less than 0.01). These features are the symmetry/asymmetry of the radiolucency in relation to the apex and the funnel-shaped/angular-shaped extension of the radiolucency. The widely accepted criteria that the possession of a radiopaque cortex surrounding the radiolucency can discriminate between a periapical cyst and granuloma cannot be statistically supported in this study.

Radiographic evaluation of lesion sizes of histologically diagnosed periapical cysts and granulomas.
A total of 149 periapical lesions were classified histologically into cysts, granulomas and other lesions. It was found that 53% were cysts, 39% were granulomas and 8% were other lesions. Of the 149 periapical lesions classified, 69 selected cases of cysts and granulomas were obtained and radiographic measurements of area (mm2), largest diameter (mm) and largest root-to-border distance (mm) were recorded. It was found that there is an apparent increase in cystic prevalence with an increase in the area, largest diameter or largest length of the periapical lesions radiographically. A cystic prevalence of 92-100% is observed with a radiographic area of greater than 200 mm2, a radiographic distance and diameter of greater than 20 mm.

Subdiaphragmatic abscesses: myths and realities. A report on sixty-two cases.
The main cause (60.8%) of subdiaphragmatic abscesses in a series of 62 patients (of which 46 were males), was found to be hepatobiliary in nature. Radiology proved to be helpful in correct diagnosis (61%), as did ultrasonography (60%). Right sided subdiaphragmatic abscesses were (55/62) 88.7% of the total. Mean abscess volume was 500 ml while culturing efforts were in vain in 32% of the abscess cases (able to be cultured). The incidence of morbidity was (12/62) 19.4% and mortality (3/62) 4.8% in this series, where the treatment was solely through surgical drainage. Though closed drainage using ultrasonic guidance has been popular in the past decade, it has its drawbacks. Open surgical drainage therefore, as a well established mode of treatment, is recommended.

Surgical treatment of hydatid cysts of the pancreas.
This series consists of seven patients with hydatid cysts of the pancreas; five females and two males, with an average age of 31 years. In a follow-up extending up to 33 years, about a 50% rate of correct preoperative diagnosis was recorded. The most sensitive and effective diagnostic modalities such as latex agglutination, ultrasonic, radionuclide, computerized tomographic and magnetic resonance imaging techniques were not available till the late seventies and therefore were only used during diagnosis of the latter 3 cases. Four patients had cysts located in the head of the pancreas. Three cysts were situated in the body and tail. Two distal pancreatectomies, two cystectomies and three marsupialization and external drainage procedures were performed for the surgical management of these cases. Two of the marsupialized and externally drained patients had fistulas which eventually dried up within a month leading to a total morbidity of 29% and a mortality rate of nil.

Psychiatric complications of corticosteroid therapy.
Despite limited evidence, the general consensus is that corticosteroids can cause psychiatric complications, mainly depression. This is most noticeable in high doses or in medical conditions with neuropsychiatric sequelae. The prognosis is usually good if corticosteroids are discontinued, but further study of the prevalence of psychiatric reactions, their mechanism of action and appropriate treatment is necessary.
