Acute infantile hemorrhagic edema (AIHE) is a cutaneous leukocytoclastic vasculitis, clinically characterized by the symptom triad of fever, large purpuric skin lesions, and edema. The clinical picture has a violent onset, a short benign course, and spontaneous complete recovery. In this article, we present eight patients who were admitted with rashes on the skin and edema on the eyelids and extremities, and were diagnosed with AIHE according to their clinical and histopathological features (immunohistological study was also performed in three of them). Our purpose was to emphasize that, aside from Henoch‐Schönlein purpura, meningococcemia, septicemia, and purpura fulminans, AIHE benign disorder should also be considered in the differential diagnosis to determine the clinical course and treatment protocol in patients with purpuric rashes.

Summary Thyroid carcinoma and benign thyroid diseases associated with primary hyperparathyroidism (PHPT) may cause difficulties in the diagnosis, localization and therapy of PHPT. In this study, we analysed coexistent thyroid pathologies in 51 patients who underwent neck exploration with a diagnosis of PHPT between 1999-2002. Five hundred thirteen patients who underwent thyroidectomy for nodular thyroid disease without a parathyroid pathology in histopathological examination served as controls. In patients with PHPT there were 43 cases (84.3%) of coexistent thyroid pathology. Nine patients (17.6 %) had coexistent papillary thyroid cancer. Nine patients (17.6 %) had lymphocytic thyroiditis, two (3.9%) had benign thyroid adenoma and 24 (47%) had nodular hyperplasia. In one patient (2%), there was intrathyroidal metastasis from a parathyroid cancer. One patient had coexistent lymphocytic thyroiditis and multifocal papillary cancer. One of the two cases with thyroid adenomas was Hürthle cell type. In the control group only 28 patients (5.5%) had thyroid malignancy (27 papillary cancer and one follicular cancer). In conclusion, the coexistent thyroid pathologies are highly prevalent in patients with PHPT and pre-and intra-operative thyroid examination should be performed to avoid overlooking important thyroid pathologies.

OBJECTIVES To examine our patients with brucellosis and renal involvement. Although brucellae have been recovered from the urine of patients with brucellosis, renal involvement is uncommon. METHODS The data from 15 patients (8 males and 7 females, mean age 43 +/- 18.9 years, range 16 to 80), who had been admitted to our hospital with the diagnosis of brucellosis with renal involvement from 1998 to 2006, were retrospectively evaluated. RESULTS In almost all cases, urinalysis revealed hematuria and variable amounts of proteinuria; some of the patients had pyuria. Of the 15 patients, 14 had renal failure. The etiology of renal failure was prerenal azotemia in 1, acute tubular necrosis because of nonsteroidal anti-inflammatory drug use in 1, anuric tubulointerstitial nephritis due to rifampin use in 1, nephritis accompanied by brucellar endocarditis in 3, brucellar endocarditis and tubulointerstitial nephritis-associated vasculitis in 1, brucellar membranoproliferative glomerulonephritis in 1, and brucellar tubulointerstitial nephritis clinically in 6 patients. Hemodialysis was required in 5 patients. Chronic renal failure developed in 1 patient, 2 patients were lost to follow-up, and renal function completely recovered in 11 patients. Two patients underwent renal biopsy and membranoproliferative glomerulonephritis with intraglomerular infiltration of histiocytes was identified in 1 patient and chronic tubulointerstitial nephritis associated with vasculitis and immune complex nephritis features was identified in the other. CONCLUSIONS In areas endemic for brucellosis, this infection can be associated with hematuria, proteinuria, and renal failure. In addition, many diverse etiologies can play a role in the renal involvement associated with Brucella infection.

Abstract Background: In recent years, many surgeons dealing with endocrine surgery have increasingly performed total thyroidectomy for benign thyroid disease. However, total excision of the thyroid in the treatment of benign lesions has been surrounded by even more controversy than its role in cancer treatment. The complication rate appears to be higher when the operation is done by inexperienced surgeons who have no special skills in endocrine surgery using proper techniques. The aim of this study is to determine whether surgeons experience and the refinement of surgical techniques are associated with postoperative recurrent laryngeal nerve (RLN) palsy or hypocalcemia after total thyroidectomy for benign thyroid disease. Methods: A total of 68 consecutive patients who underwent total thyroidectomy for benign thyroid disease were reviewed. Twenty-six of these were from between January 1998 and June 1999 (first period) and 42 from between June 1999 and September 2000 (second period). Patients were divided into two subgroups according to different periods and different surgical techniques to identify the RLNs and the parathyroid glands. RLNs function was evaluated pre-and post-operatively by an otolaryngologist, and serum calcium levels were measured at the postoperative follow-up. Results: During the first period of the study, transient hypocalcaemia was determined in 8 (31%) patients. Hypocalcaemia was clinically symptomatic in 5 (19%) patients. Transient RLN palsy developed in 4 (15%) patients. Unilateral permanent RLN palsy due to operative injury was observed in 1 (4%) patient. During the second period, we noted transient hypocalcemia in 11 (26%) patients and symptomatic hypocalcemia in 6 (4%) patients. Serum calcium levels returned to normal within 4 weeks after operation in all patients. Neither transient nor permanent RLN palsy was observed during this period. Conclusions: Complications of total thyroidectomy can be minimized with increasing experience and the refinement of surgical technique.

Abstract Purpose: The aim of this study is to evaluate our approach to patients with squamous cell carcinoma of lower lip. Patients and methods: This study includes 31 lower lip squamous cell carcinomas followed up between 1994 and 2000. Primary treatment was applied to 28 patients of whom 23 were in stages I-II and five in stages III-IV. Three patients presented locoregional recurrence. Neck dissection was performed during primary lip resection in patients with palpable cervical lymph node involvement. Patients with unpalpable cervical lymph nodes were divided into two subgroups: one was submitted to elective neck dissection (n = 11) and the other had isolated lip resection (n = 8). Unilateral or bilateral selective supra-omohyoid neck dissection (SOHND) was performed according to the localisation of the disease. Radical dissection was performed in a secondary intervention, when SOHND revealed lymph node metastases. Radiotherapy and chemotherapy were applied for curative and/or adjuvant treatment in addition to surgery in patients with locoregional recurrence and metastatic lymph nodes or with perineural involvement. Results: Occult cervical metastasis within a single lymph node was found in one of the 11 No patients who underwent elective neck dissection. Delayed neck metastasis developed in one of the eight patients in whom isolated lip resection (without neck exploration) was performed. Chemoradiotherapy was administered to this patient, but he died. Neck metastasis was established histologically in four of five patients in stages III-IV. Postoperative radiotherapy was used on these patients. One of the patients in this group died due to inoperable local recurrence in the neck, another died because of distant metastasis. Local mandibular recurrence was seen in one of these patients after three years. Comment: Six patients (19%) died due to lower lip carcinoma in this series. Our findings show the importance of elective neck dissection and intact surgical resection margins.

Abstract.Malignant fibrous histiocytoma occurs most commonly in the extremities and trunk, but rarely in the visceral organs. Malignant fibrous histiocytoma of the small intestine is an extremely rare condition. To our knowledge, only ten cases of primary tumors involving the small intestine have been described up to now. Among them only one case has been reported to lead to intussusception. This case report documents the appearance of a storiform-pleomorphic type primary malignant fibrous histiocytoma of the ileum, which led to intussusception, in a 58-year-old man with a 3-month history of dyspepsia, weight loss, general fatigue, and nonspecific abdominal pain. The patient was well with no sign of disease at 8 months after surgery. The clinical and pathologic characteristics of malignant fibrous histiocytoma of the small intestine as found in the literature are also reviewed.

Mustafa Kösem; Cretin Kotan; Ekrem Algün; Cevat Topal

Abstract.We report the case of a simultaneous occurrence of papillary intrafollicular and microcarcinomas with bilateral medullary microcarcinoma of the thyroid in a patient with multiple endocrine neoplasia type 2A. The concurrent presence of two thyroid carcinomas is rare. The simultaneous occurrence of two different tumors in the same thyroid each being multifocal and smaller than 1 cm in diameter has not been previously reported in the literature. Furthermore, we define the first case of intrafollicular papillary thyroid carcinoma (carcinoma in situ).

BackgroundThe aim of this study was to assess the effect of Ginkgo biloba extract (EGb 761) on healing of experimental colonic anastomoses in a rat model.MethodsRats were divided into four groups: postoperative day (POD) 3 untreated control group, POD 3 EGb 761 group, POD 7 untreated control group, and POD 7 EGb 761 group. In the oral EGb 761 groups, the agent was given at 9.6 mg daily per orogastric route using a 4-F fine feeding catheter. We measured bursting pressures and hydroxyproline content and histologically examined the resected anastomoses on POD 3 and POD 7.ResultsThe bursting pressures increased more in the EGb 761 group than in the untreated control group on POD 3, but this difference was not statistically significant. Hydroxyproline content was higher in the EGb 761 group than in the untreated control group on POD 3, and this difference was statistically significant. Anastomosis bursting pressure values and hydroxyproline contents were significantly higher in the EGb 761 group than in the untreated control group on POD 7. Histological examination showed greater fibroblastic activity in the EGb 761 group than in the untreated control group on POD 3. There was no significant difference in anastomotic polimorphonuclear leukocyte, mononuclear cells and blood vessel neodevelopment between the POD 3 groups, but there was significant difference in fibroblastic activity and blood vessel neodevelopment between the POD 7 groups.ConclusionsThese results showed us that EGb 761 administration resulted in enhanced stability of colonic anastomoses during the first postoperative week.

Hakan Çankaya; Mustafa Kösem; Muzaffer Kiris; Abdurrahman Üner; Ahmet Metin

Hypohidrotic ectodermal dysplasia (Christ-Siemens-Touraine syndrome) is characterized by partial or complete absence of sweat glands, hypotrichosis, hypodontia, prominent frontal ridges and chin, saddle nose, sunken cheeks, thick, everted lips, large ears and sparse hair. While association of other ectodermal dysplasia syndromes with tumors such a non-Hodgkins lymphoma, hamartoma, keratoakanthoma, Merkel-cell cancer, squamous-cell carcinoma, syringofibroadenomatosis has been reported, association of hypohidrotic ectodermal dysplasia and a tumor has not been reported. In a five-year-old male patient admitted with nasal obstruction and nasal mass complaints, we have reported firstly an association of hypohidrotic ectodermal dysplasia and nasopharyngeal rhabdomyosarcoma.
