Is testicular perfusion influenced during laparoscopic inguinal hernia surgery?

BACKGROUND: The influence of laparoscopic inguinal hernia surgery is still unclear. The aim of this study was to compare the possible early effects of laparoscopic and open inguinal hernia repair on testicular perfusion. METHODS: In this prospective trial, 44 patients underwent mesh repair of a primary inguinal hernia assigned to one of two procedures: open anterior mesh repair (n = 29) or a laparoscopic totally extraperitoneal approach (n = 15). Doppler ultrasound was used to determine the hemodynamic characteristics of the testicular blood flow. RESULTS: No statistically significant differences were found between the two groups in terms of Doppler flow parameters for the preoperative, very early (day 1), and early postoperative (day 7) periods. When Doppler flow parameters of the testicular artery were compared in the conventional group, statistically significant differences were found between preoperative and very early postoperative values (p < 0.05). Meanwhile, comparison among flow parameters of the testicular, capsular, and intratesticular arteries of the laparoscopic group showed statistically significant differences between preoperative and very early postoperative and between preoperative and early postoperative values (p < 0.05). There were no statistically differences in postoperative complications between the two groups. CONCLUSION: Testicular blood flow is influenced during laparoscopic inguinal hernia surgery. Whether changes in flow parameters remain in the late postoperative period, and whether they have an impact on complications will be evaluated in further studies.

Acute hepatic vein thrombosis after liver transplantation in a child with biliary atresia and absent inferior vena cava.

Stenosis of the hepatic venous outflow anastomosis is rare after liver transplantation. Hepatic venous outflow obstruction affects 5.1% to 7% of transplanted patients. Clinical findings among children include massive ascites and abdominal pain and laboratory findings demonstrate altered liver function tests and coagulopathy. In this article, we report a case of hepatic venous thrombosis occurring 22 days after living-related liver transplantation. The patient was treated with hepatic venoplasty and stent implantation.

The incidence and management of acute and chronic rejection after living donor liver transplantation.

Living donor liver transplantation (LDLT) is a good alternative to cadaveric liver transplantation for end-stage liver disease. Herein we report the outcome of 132 LDLTs performed between 1999 and 2005, with special emphasis on the incidence and management of acute and chronic rejection. Among the LDLT population a first acute rejection episode (ARE) was clinically suspected in 24% and proven by liver biopsy in 11%. According to the Banff classification, 50% of AREs were grade 1, and 50%, grade 2. There was no grade 3 AREs. The first ARE occurred between 7 days and 23 months posttransplantation (mean 97 days, median 70 days). Ninety-seven percent (31/32) of the AREs occurred within the first year after transplantation and 3% (1/32) in the second year. Among the patients with ARE, 23% developed a second ARE between 4 and 11 months. A third ARE was detected in 8% of patients after month 18. All AREs responded to adjustment of immunosuppressive doses or steroid boluses. Chronic rejection (CR) was detected in 2%. In conclusion, the incidences of ARE and CR are consistent with the previously reported data. Acute and chronic rejections seem to be mild and easily manageable clinical conditions. Our results also showed a significant difference between clinically suspected and biopsy-proven ARE emphasizing the importance of indicated liver biopsies in the management of the LDLT population.

Multiple impacted permanent and deciduous teeth.

Multiple impacted teeth may be related to syndromes and metabolic disorders. In some cases, however, impaction of multiple teeth is not accompanied by a fixed complex of symptoms. A 55-year-old woman attended our clinic, as she was not comfortable with her prosthetic appliances because of erupted teeth. Panoramic and occlusal radiographs revealed 13 impacted teeth (12 permanent and 1 deciduous) in the maxilla and 15 impacted teeth (11 permanent and 4 deciduous) in the mandible. In total the patient had 28 impacted teeth. In our case, medical and family history and extraoral examination were not suggestive of any syndrome or metabolic disorder. In conclusion, radiographic examination may reveal multiple impactions in clinical absence of teeth. Lack of eruptive force and rotation of tooth buds may cause multiple impactions and additional examinations may be necessary to exclude systemic and metabolic conditions.

Incidence of canine impaction and transmigration in a patient population.

In this study, 4500 consecutive panoramic radiographs were prospectively reviewed. The incidence of canine impaction was found to be 3.58% and the incidence of canine transmigration was 0.31%. There were six maxillary and eight mandibular transmigrant canines. The incidence of impacted canine teeth and transmigration of maxillary and mandibular canines may be more frequent than was previously thought, at least in some populations.

Unusual combination of presenting features in multiple myeloma.

Initial oral signs of multiple myeloma may involve pain, paraesthesia, swelling, tooth mobility and radiolucency. A 62-year-old female patient presented with the chief complaint of numbness in the right lower jaw. Intraoral examination revealed no abnormalities and her history was non-contributory. A panoramic radiograph revealed an irregular, small radiopacity in the premolar region and small, multiple and diffuse osteolytic alterations in the mandible. Computed tomography revealed maxillary and mandibular cortical destruction. An incisional biopsy was performed. The histopathological diagnosis was plasma cell myeloma and further investigations lead to the diagnosis of multiple myeloma. Dysfunction of a nerve coursing through diseased bone is an ominous sign and may be an indication that a malignant process is present.

Transmigration of impacted canines.

Pre-eruptive migration of a tooth across the midline is termed "transmigration". This condition has not been reported for teeth other than mandibular canines. Bilateral transmigration is extremely rare, and associated pathological lesions are also reported. The aim of this report is to present the first case of maxillary canine transmigration as well as additional cases of transmigrated mandibular canines, with special emphasis on their classification.

Tuberculous lymph node calcification detected on routine panoramic radiography: a case report.

Cervical lymph node calcification is usually asymptomatic and may be found on a routine panoramic survey. Such calcifications in tuberculosis occur most often after caseation of the node or after treatment. Our patient had lymph node tuberculosis about 50 years ago. On the panoramic radiograph, several massive, irregular, radiopaque masses were detected. These masses were regarded as submandibular cervical lymph node calcifications. We suggest that lymph node tuberculosis may have been due to ingesting milk infected with Mycobacterium bovis, and that both the delay in the diagnosis and the successful treatment was the cause of lymph node calcification.

[Coronary intervention and occupational rehabilitation--a prospective, randomized intervention study].

Coronary catheter revascularisation is less costly than bypass surgery due to lower direct (medical) and indirect costs (loss of work). Many studies show that the time patients stay out of work following coronary intervention is much longer than necessary. This leads to a considerable increase of indirect costs, which can far exceed the medical costs of the treatment. This prospective randomised study was done to determine whether specific information to patient and family doctor results in an earlier return to work. After catheter revascularisation 100 working patients (mean age 52.4 years) were randomised either to the intervention group (information to patient and family doctor) or to the control group (no specific information about return to work). Four months later 81 patients had returned to their previous jobs (mean sick leave 18.9 +/- 24.8 days) while 19 were still out of work. In the control group, the rate was 79% and the mean sick leave was 16.4 +/- 22.0 days (median 7); in the intervention group 83% had returned to work after a mean of 21.5 +/- 27.4 days (median 10). There was no significant difference between the two groups, neither according to the rate of returned workers nor to the duration of sick leave. In the subgroup of patients with a private insurance (23% of all) 96% started to work again (mean sick leave 5.7 +/- 5.1 days median 3.5), while the rate was 77% in the group of panel patients (mean sick leave 23.7 +/- 27.4 days, median 11). The difference in sick leave between these two groups was highly significant (p = 0.0003). Specific information to the patient and family doctor has no effect on the time patients stay out of work following catheter revascularisation. It seems that the observed delay depends on social and psychological factors that cannot be influenced directly.
