Effect of appendicectomy on development of right inguinal hernia.

The effect of appendicectomy on the subsequent development of right inguinal hernia was investigated in 583 patients with hernias, 42 of whom had previously had appendicectomies. The incidence of right sided hernias was no greater among these patients than among those who had not had their appendixes removed. Neither sex was more prone to develop an inguinal hernia after appendicectomy, and no type of hernia (direct or indirect) predominated. The cause of right sided inguinal herniation after appendicectomy has been thought to be damage to the nerve supply of the inguinal muscles during the appendicectomy incision. All our 42 cases except two had had their appendicectomies through classic McBurney incisions, which were some distance away from the most common areas of nerve damage. We conclude that development of a right inguinal hernia is an unlikely complication of appendicectomy if a classic McBurney incision was used.

Trace elements in hydatid disease.

The serum and cyst fluid levels of selenium, zinc and copper were investigated both in patients and sheep with hydatid cysts. Results were compared with those of healthy subjects in both species. The serum values of Se, Zn and Cu in healthy subjects were 60.24 +/- 1.96 micrograms/L, 0.59 +/- 0.07 mg/L, and 1.01 +/- 0.08 mg/L, respectively. The corresponding serum values of the three trace elements in patients with hydatidosis were 41.30 +/- 1.94 micrograms/L, 1.27 +/- 0.08 mg/L, and 0.89 +/- 0.09 mg/L. These results show a decrease in Se and Zn, and a rise in Cu in sera of patients with hydatid disease. Similar results were obtained in infested sheep as related to the healthy control animals. Our results on the three trace elements were found to correlate well with the incidence of cirrhosis, malignant and infectious diseases and arthritis. Se was not detectable in cyst fluid, while Cu and Zn levels were found significantly lower than serum levels. Cu and Zn levels in cyst fluid showed no difference in both species. Variations in serum Cu, Zn and Se levels were insignificant with regard to the genus of the host and the fertile capacity of the hydatid cyst.

Bezoars--analysis of seven cases.

From 1979 to 1986 seven patients were studied in whom bezoars had been diagnosed. The history of five patients revealed that they had eaten a fruit called prunus lauricerasus, grown in the east Black Sea region. This is quite different from persimmons which are well-known as an aetiological agent of phytobezoars. Trichobezoars were present in one case, and phytobezoars in five cases. In one case, trichophytobezoar was removed surgically from the stomach. Our five cases were operated on to treat small bowel obstruction. Surgery was performed in all our cases and prunus lauricerasus should be kept in mind as an aetiological factor besides persimmons.

Ultrasound diagnosis of liver hydatid disease.

A clinical study of 42 patients with hydatid disease was carried out using a real-time gray scale B-scanner. All cases were confirmed surgically. The ultrasound characteristics of the hydatid cysts were classified into three groups: Type I, simple hydatid cyst (19 of the 42 cases), type II, hydatid cyst with a disrupted wall and septa (14 cases), and type III, hydatid cyst with a heterogeneous echo pattern (9 cases). It was concluded that ultrasound classification of the cysts increases diagnostic accuracy. However, if a hydatid cyst becomes secondarily infected these typical changes are lost and the ultrasound diagnosis may then become more difficult. Periodic examinations should be performed with ultrasound after surgery.

Changes in ionized calcium content and related clinical chemical parameters in cases of left-sided abomasal displacement.

There is still uncertainty about the etiology and pathogenesis of abomasal displacement. Changes in total and ionized calcium are considered to be important pieces in the mosaic of causative factors. The present study on pre- and postoperative clinical chemical changes revealed a preoperative reduction in ionized calcium values. The reduction seemed mainly to be due to changes in the pH of blood.
