Albendazole Therapy in the Treatment of Hydatid Liver Disease

Hydatid disease, a common health problem in Turkey as in many countries, should be included in the differential diagnosis of all patients presenting with a cystic mass in the abdominal or thoracic cavity. Previously, surgery had been the main form of treatment. But with the introduction of preoperative medication with albendazole, treating this disease medically is now growing in popularity. We report herein the findings of ten patients with two lung and 20 liver hydatid cysts ranging from 3 to 20 cm in diameter, who were successfully treated with medical therapy. Multiple organ involvement and multiple cysts in an organ are the main indications for medical treatment with albendazole, but the indications should not be limited to certain situations such as small-sized cysts, since even huge-sized cysts responded well to the therapy in this series.

Diagnostic value of blood D-dimer level in acute mesenteric ischaemia in the rat: an experimental study

OBJECTIVE: The high mortality rate of mesenteric ischaemia is mainly due to delay in diagnosis. For this reason, it is of great importance to find a specific and rapidly elevating marker. The present study investigated the diagnostic value of blood D-dimer level as a potential marker for acute mesenteric ischaemia in a rat model. METHODS: Thirty male Wistar albino rats were divided into three groups. Basal D-dimer and L-lactate levels were determined in the non-operative control group (I). In the operated control group (II), the superior mesenteric artery was simply manipulated, while the artery was ligated in Group III. Blood samples were drawn in all groups for D-dimer and L-lactate assays. RESULTS: Both Group II (p=0.016) and Group III (p=0.001) had significantly higher mean D-dimer levels in the first postoperative hour compared with the basal level in Group I. However, there was no difference between the levels in Groups II and III. The mean level in Group II in the sixth hour had dropped to a statistically insignificant level compared with the basal value, while the mean value in Group III kept rising during this period (p=0.001). Nevertheless, there was no significant difference between Groups II and III. On the other hand, the mean L-lactate level in the first postoperative hour in Group III was significantly higher than the basal level in Group I (p=0.003). No significant rises were recorded in Group II in the first and sixth postoperative hours. The difference between Groups II and III in the first hour was significant (p=0.005). Group III also had significantly higher mean serum L-lactate value in the sixth hour compared with both the basal value in Group I (p=0.001) and the sixth-hour value in Group II (p=0.003). CONCLUSION: These results do not adequately support the use of blood D-dimer level as an independent parameter in the diagnosis of mesenteric ischaemia due to arterial thrombosis. However, this parameter can be used together with other tests in eliminating the possibility of a thromboembolic event.     

The effects of different hernia repair methods on postoperative pain medication and CRP levels

Although tension-free techniques of hernia repair using synthetic meshes have yielded encouraging results, the best method of inguinal hernia repair is still unclear. The aim of this study was to compare the responses of inflammatory mediators and postoperative pain relief following laparoscopic total extraperitoneal (TEP) hernioplasty, open tension-free mesh hernioplasty (Lichtenstein), posterior preperitoneal mesh hernioplasty (Nyhus procedure), and Bassini procedure. Patients with primary inguinal hernia were randomized in the operating room to undergo one of these repair techniques. Group I comprised 24 patients treated by Lichtenstein procedure; Group II comprised 21 patients treated by Nyhus procedure; Group III comprised 19 patients treated by Bassini procedure; and Group IV comprised 20 patients treated by laparoscopic TEP mesh hernioplasty. Postoperative pain levels following hernia repair were compared by measuring the use of patient-controlled analgesia (PCA) during the 24 hours after surgery. Serum samples withdrawn before surgery and 48 hours after surgery were assayed for C-reactive protein (CRP) content. Patient characteristics, operating time, and operative and early complications were noted. Serum CRP levels rose markedly following Nyhus (184.5 +/- 41.6 mg/L), Lichtenstein (138.4 +/- 72.5 mg/L), and Bassini repair (137.2 +/- 55.9 mg/L) compared with that of patients who underwent TEP mesh hernioplasty (55.5 +/- 41.2 mg/L). There were also significant differences in the postoperative need for analgesics via PCA among patients undergoing Nyhus (382.9 +/- 189.1 mg), Bassini (303.2 +/- 173.7 mg), and Lichtenstein (253.9 +/- 129.3) procedures compared with 196.6 +/- 148.8 mg for the TEP mesh hernioplasty group. Patients in the Lichtenstein group also had significantly less need of analgesics than those in the Nyhus and Bassini groups. In conclusion, TEP mesh hernioplasty is less traumatic and yields less postoperative pain than the Nyhus, Lichtenstein, and Bassini procedures.     

Giant cell glioblastoma manifesting as traumatic intracerebral hemorrhage--case report

A 33-year-old male presented with intracerebral hemorrhage in the left temporoparietal region after a traffic accident. Ten months later, the traumatic hemorrhage was found to originate in an underlying giant cell glioblastoma. Our case indicates that non-traumatic underlying pathologies, such as vasculopathies, coagulopathies, or tumors, should be considered in the differential diagnoses of intracerebral hemorrhage occurring in unusual locations after traumatic accidents.     

Acute renal failure associated with nonfulminant hepatitis A virus infection

Hepatitis A is usually a mild self-limiting infection of the liver. Nonfulminant acute renal failure very rarely complicates type A viral hepatitis. An unusual case, a 32-year-old female with serologically proven acute hepatitis A infection, was complicated by acute renal failure and the patient in this study is the first case associated with Cushing's disease. She recovered, and the laboratory tests returned normal one month after initial hospitalization. Although the mechanism responsible for renal failure in acute hepatitis A virus infection is still uncertain, possible causes are discussed with the review of literature.     

Follow-up problems and changes in obliteration of the residual cystic cavity after treatment for hepatic hydatidosis

Background/Purpose. In this prospective open clinical study, we investigated the problems that might arise during the obliteration of the residual cavity in hepatic hydatidosis. These problems might be related to the duration of the obliteration period and to the effects of omentoplasty on the residual cavity. Methods. We operated on 54 hepatic hydatidosis patients with cystodrainage and omentoplasty. We followed these patients for a period of 8 years after the operation. We used ultrasonography (US) to evaluate the obliteration of the cystic cavity; evaluations were made by serological tests as well (hemagglutination test, IHA, and IgE radioallergosorbent test, RAST). Results. Most of the reductions in the size of the cystic cavity were observed within the first 30 days following the operation (69.7%). At the end of the first postoperative year, cystic cavity obliteration was not complete in 34 patients, and 5 of these cases had positive indirect IHA and IgE RAST tests for Echinococcus granulosus. These patients were treated with extension of albendazol therapy. In 2 of these 5 patients, obliteration of the cystic cavity was complete within 12 months; their serological tests became negative at 15 and 21 months, respectively. In the remaining 3 whose serological tests were still positive at the end of the first year, obliteration of the cystic cavity was complete by 27, 33, and 45 months respectively. Of these 3 patients, the tests became negative at 30 and 52 months for the first 2 patients; the last patient is still serologically positive although we have not determined any findings related to the recurrence of the cyst. Conclusions. Omentoplasty is the preferred method in the surgical treatment of hepatic hydatidosis. However, we should keep the following facts in mind while following these patients with US: the technique can be insufficient, the obliteration of the residual cavity takes time and can be misdiagnosed as a recurrence, and ultrasonographic appearances can mimic some other diseases whether they are benign or malignant. Moreover, follow-up studies should be complemented with the serological tests. Thus, all these steps will minimize a misdiagnosis and unnecessary reoperations for hepatic hydatidosis.     

Evaluation and therapeutic regulation of erectile dysfunction with visual stimulation test. An objective approach by using sildenafil citrate test

AIM: An objective evaluation of the psychogenic cause of erectile dysfunction by performing the visual stimulation tumescence and rigidity (VSTR) test and sildenafil citrate test, together with the effectiveness of sildenafil citrate medication on impotence caused by different etiologies. MATERIAL AND METHODS: Between 1998 and 2000, a total of 36 men (12 patients with diabetic etiology, 5 patients with vasculogenic risk factor) were enrolled in this study. The mean age of patients was 53 (27-67) years. Following standard questionnaires, including a detailed anamnesis from an andrologic viewpoint, VST was performed in an ambulatory setting and beginning with a test dose of 50 mg. At the end of 2 h, the data was evaluated with computer assistance (Rigiscan device) and if a satisfactory erection had not occurred, an additional second dose of sildenafil citrate (50 mg) was given until there was a satisfactory erection. Results obtained from VST: results were classified as group I (fully rigidity, >10 min erection, >70% of rigidity, possible vaginal penetration), group II (unstable erection, 5 min erection, >70% of rigidity, possible vaginal penetration) and group III (tumescence without rigidity, <5 min erection, <70% of rigidity, impossible vaginal penetration). The results obtained during the first 1 h of the VSTR test were regarded as the patient's own erectile condition and later data was accepted as the real effect of sildenafil citrate. The Fisher exact test was used for statistical evaluation including pre- and post-sildenafil effect on erectile rigidity and duration of erection. RESULTS: The erection status of patients was sufficient in 17 (47.2%) in group I, it was insufficient but sufficient enough with an increased dose of sildenafil citrate in 10 (27.7%) in group II, and insufficient without/with full dose of sildenafil citrate in 9 (25%) in group III. Considering rigidity and total erectile period, there was a statistical significant difference between the first two groups with respect to the early and late sildenafil citrate effects on the VSTR test (p < 0.05). Again, 10 patients with known risk factors (diabetes mellitus 5 and vasculogenic 5) in the second group seemed to give a good response to repeated dosage of sildenafil citrate which has been found to be very interesting. However, the rest of the diabetic patients (n = 7) in the third group showed no erection despite the increasing and repeated doses of sildenafil citrate. CONCLUSION: Sildenafil citrate with the VSTR test has effective and reliable results which was regarded as very important to diagnose and determine objectively the amount of therapeutic doses in impotence. In accordance with the literature data, our results also confirm the reliability and the practical nature of the VSTR test, which is less time-consuming and cheaper than the nocturnal penile tumescence and rigidity (NPTR) test. In the VSTR test, necessary doses of medication needed for satisfactory erection were easily regulated in patients with certain kinds of impotence. Additionally, self-criticism advantage of the patients on erection and an unnecessary need for regular sexual partners may make this test preferable in the near future. However, we believe that a large group of patients with other definite parameters are certainly needed in order to obtain more reliable data.     

Embolization of uterine artery in terminal stage cervical cancers

Ligation of the hypogastric artery has been a standard and effective procedure in controlling massive bleeding in advanced cervical carcinoma. The authors wanted to demonstrate the selective use of embolization of hypogastric or uterine artery to achieve the same end result--the stoppage of vaginal bleeding. In a number of cases, surgical approach may not be appropriate either because of the critically ill patient or because of the highly deformed pelvic anatomy due to radiotherapy or to the recurrence of cancerous tissue. As an alternative therapy, we used selective embolization of the uterine artery in eight patients. In all the patients, embolization served to control bleeding. As the bleeding was brought under control, a gradual recovery of the patient was generally observed. The most common side-effect was temporary severe pain related to ischemia of tumoral tissue. Embolization may be regarded as an effective procedure, which can be used to control massive bleeding in selected cervical cancer patients.
