Management of idiopathic granulomatous mastitis: dilemmas in diagnosis and treatment

BackgroundIdiopathic granulomatous mastitis (IGM) is a rare inflammatory disease.Because of it’s uncommon etiology and rareness, diagnosis and treatment is still a challenge. Owing to wide spectrum of IGM it is difficult to standardize and optimize the treatment. The aim of this study was to report and describe the clinical signs, radiological findings, management, clinical course and the recurrence rate of the patients which were treated due to IGM.MethodsIn this retrospective review of patients diagnosed with IGM histopathologically between January 2006 and December 2011, medical reports, ultrasonography (US) and mammograhy (MMG) findings, follow-up information and recurrence were obtained from records.ResultsPainful, firm and ill defined mass was the symptom of all patients. While parenchymal heterogeneity, abscess and mass were the findings of US, increased asymmetric density was the main finding of MMG. Wide local excision was performed in 15 (62.5%) patients, incisional biopsy with abscess drainage was performed in 9 (37.5%) patients. Median follow-up was 34.8 (range 10–66) months.ConclusionsWhile the physical examination give rise to thought of breast carcinoma, the appearance of parenchymal heterogeneity and abscess formation on US especially with enlarged axillary lymph nodes support the presence of an inflammatory process. But these findings do not exclude carcinoma. Hereby, histopathologic confirmation is mandatory to ensure that a malignancy is not missed.

Early versus delayed laparoscopic cholecystectomy for acute cholecystitis: a prospective, randomized study.

We aimed to compare the clinical outcome and cost of early versus delayed laparoscopic cholecystectomy for acute cholecystitis. Sixty patients with acute cholecystitis were randomized into early (within 24 hours of admission) or delayed (after 6-8 weeks of conservative treatment) laparoscopic cholecystectomy groups. There was no significant difference between study groups in terms of operation time and rates for conversion to open cholecystectomy. On the other hand, total hospital stay was longer (5.2 ± 1.40 versus 7.8 ± 1.65 days; P = 0.04) and total costs were higher (2500.97 ± 755.265 versus 3713.47 ± 517.331 Turkish Lira; P = 0.03) in the delayed laparoscopic cholecystectomy group. Intraoperative and postoperative complications were recorded in 8 patients in the early laparoscopic cholecystectomy group, whereas no complications occurred in the delayed laparoscopic cholecystectomy group (P = 0.002). Despite intraoperative and postoperative complications being associated more with early laparoscopic cholecystectomy compared with delayed intervention, early laparoscopic cholecystectomy should be preferred for treatment of acute cholecystitis because of its advantages of shorter hospital stay and lower cost.

Comparison of modified Limberg flap and Karydakis flap operations in pilonidal sinus surgery: prospective randomized study.

The best surgical technique for pilonidal sinus disease (PSD) is still disputed. The objective of this prospective randomized study is to compare the short and long-term results of modified Limberg flap and Karydakis flap surgeries that have been widely used in recent years. Ninety one patients were included in the study. The patients were divided into two groups: modified Limberg flap (MLF; n = 46) and Karydakis flap (KF; n = 45). Preoperative findings of the patients, their surgical findings, and short and long-term postoperative findings were recorded and statistically compared. While no significant difference was discovered between the groups in terms of postoperative analgesic need, hospital stay, postoperative infection rate, drain stay time, painless sitting time, painless toilet-sitting time, and painless walking time, return to work or school time was shorter in the MLF group compared with the KF group (20.61 ± 7.89 days, 23.29 ± 6.42, respectively; P < 0.05). Cosmetically, the visual analog scale (VAS) of the KF group was significantly higher than that of the MLF group (VAS score 7.12 ± 1.28, 5.45 ± 1.77, respectively; P < 0.05). Considering recurrence rates, no statistically significant difference was found between the groups. Our study found out that short and long-term results of the MLF and KF procedures are similar. We believe both methods can be safely used in surgical PSD treatment given that in the MLF procedure, shorter return-to-work time is achieved, while the procedure provides better cosmetic results.

Sonographic and sonoelastographic findings of a rarely seen soft tissue tumor: eccrine spiradenoma

Eccrine spiradenoma is a rare benign tumor originating from sweat glands. Its sonographic characteristics have been described in only a few reports, and there is no such report available that describes sonoelastographic findings of this tumor. In this case report, we aimed to define the sonographic and sonoelastographic findings of a benign eccrine spiradenoma.

Nonfunctional Pancreatic Neuroendocrine Tumors: Advances in Diagnosis, Management, and Controversies

In this article, we aimed to review the literature on the clinics and management of nonfunctional pancreatic neuroendocrine tumors (NPNET). Pancreatic neuroendocrine tumors (PNET) are rare tumors with a <1/100,000 incidence and constitute approximately 2 to 10% of all pancreatic tumors. Nonfunctional PNETs are difficult to detect at early stages since they have no symptoms. Except those detected accidentally during different diagnoses, the majority of PNETs are detected in the advanced stages, with symptoms related to tumor size or liver metastasis. We reviewed the studies published in the English medical literature through PubMed and summarized the clinical features and current approaches to the treatment and follow-up of the NPNET. The common imaging techniques used for the detection of tumor localization, size, locoregional, and metastatic involvement are contrasted computed tomography, magnetic resonance imaging, endoscopic ultrasonography, and somatostatin receptor scintigraphy. Surgical resection is the only curative treatment. However, in advanced locoregional disease and liver metastasis, interventive ablative therapies such as palliative reductive surgery, selective hepatic arterial embolization, radiofrequency ablation; and systemic therapies, such as peptide receptor radionuclide therapy, chemotherapy, somatostatin analogous therapy, interferon, VEGF inhibitor, and mTOR inhibitor may be used as symptom relieving or may improve progression-free survival and total survival. Current knowledge on NPNET shows that the treatment should be personalized considering the prognostic features and life expectancy of the patient.

Correlation between the serum and tissue levels of oxidative stress markers and the extent of inflammation in acute appendicitis

OBJECTIVES: To determine the serum and tissue levels of markers of impaired oxidative metabolism and correlate these levels with the histopathology and Alvarado score of acute appendicitis patients. METHOD: Sixty-five acute appendicitis patients (mean age, 31.4±12.06 years; male/female, 30/35) and 30 healthy control subjects were studied. The Alvarado score was recorded. Serum samples were obtained before surgery and 12 hours postoperatively to examine the total antioxidant status, total oxidant status, paraoxonase, stimulated paraoxonase, arylesterase, catalase, myeloperoxidase, ceruloplasmin, oxidative stress markers (advanced oxidized protein products and total thiol level) and ischemia-modified albumin. Surgical specimens were also evaluated. RESULTS: The diagnoses were acute appendicitis (n = 37), perforated appendicitis (n = 8), phlegmonous appendicitis (n = 12), perforated+phlegmonous appendicitis (n = 4), or no appendicitis (n = 4). The Alvarado score of the acute appendicitis group was significantly lower than that of the perforated+phlegmonous appendicitis group (p = 0.004). The serum total antioxidant status, total thiol level, advanced oxidized protein products, total oxidant status, catalase, arylesterase, and ischemia-modified albumin levels were significantly different between the acute appendicitis and control groups. There was no correlation between the pathological extent of acute appendicitis and the tissue levels of the markers; additionally, there was no correlation between the tissue and serum levels of any of the parameters. CONCLUSIONS: The imbalance of oxidant/antioxidant systems plays a role in the pathogenesis acute appendicitis. The Alvarado score can successfully predict the presence and extent of acute appendicitis.

Tiroidektomize hastalarda ameliyat sonrası ağrı yönetimi için lokal bupivakain kullanımı: prospektif ve kontrollü klinik çalışma

OBJECTIVE We aimed to evaluate the effect of bupivacaine and to compare the routes of administration of bupivacaine in the management of postoperative incision site pain after thyroidectomy. MATERIAL AND METHODS Consecutive patients who were planned for thyroidectomy surgery were randomized into three groups of 30 patients each: Group 1 (control group): standard thyroidectomy surgery without additional intervention; Group 2 (paratracheal infiltration with bupivacaine): following thyroidectomy, 0.25% bupivacaine was applied on the surgical area; Group 3 (subcutaneous infiltration with bupivacaine): following thyroidectomy, 0.25% bupivacaine was injected into the cutaneous, subcutaneous region and fascia of the surgical area. Postoperative pain was evaluated by a visual analog scale (VAS) at 1(st), 4(th), and 12(th) hours after thyroidectomy. Total daily requirement for additional analgesia was recorded. RESULTS The mean age of 90 patients was 44.37±13.42 years, and the female:male ratio was 62:28. There was no difference between study groups in terms of age, thyroid volume, TSH and T4 levels. VAS score of patients in paratracheal infiltration with bupivacaine group was significantly lower than control group patients at 1(st), 4(th) and 12(th) hours following thyroidectomy (p=0.030, p=0.033, p=0.039, respectively). The need for analgesics was significantly lower in both paratracheal infiltration and subcutaneous infiltration groups than the control group (86.7%, 83.0%, and 73.3%, respectively, p=0.049). CONCLUSIONS Intraoperative local bupivacaine application is effective in decreasing postoperative pain in patients with thyroidectomy.

Modified Extravesical Ureteroneocystostomy in Cadaveric Kidney Transplantation with Completely Duplicated Ureters: A Case Report

Completely duplicated ureters are not commonly used in renal transplantation due to increased risk of postoperative complications, such as urinary tract infections, stricture, reflux and urinary leakage. Although recent results have indicated that the occurrence of these complications is similar to that of a single ureter, few reports exist of renal transplantations of kidneys with ureteral duplication. Here, we report successful renal transplantation of a cadaveric kidney with completely duplicated ureters to a 52-year-old final stage renal disease patient who had been on dialysis for 19 years. A modified extravesical ureteroneocystostomy technique was employed, in which distal ureteric ends were spatulated and their medial edges were approximated. Double-j stent catheters were inserted during the ureteroneocystostomy and removed after 21 days when progressive serum creatine levels had decreased. During 6 months following the operation so far, no urinary tract infections, hydronephrosis, pyelonephritis, stricture, or reflux was reported. We conclude that modified extravesical ureteroneocystostomy, a newly described technique is suitable for the transplantation of a cadaveric kidney with complete ureteral duplication.

Effect of Intraoperative Valsalva Maneuver Application on Bleeding Point Detection and Postoperative Drainage After Thyroidectomy Surgeries

The purpose of this paper was to analyze the effect of Valsalva maneuver application before finalizing thyroidectomy operations on the identification of bleeding points and postoperational drainage. One hundred patients (age range, 24-76 years) with multinodular goiter, recurrent multinodular goiter, toxic diffuse multinodular goiter, or papillary thyroid cancer were included in the study and were divided into 2 groups of 50 randomly. Both groups underwent thyroidectomy operation, only 1 group received intraoperative Valsalva maneuver application (twice, 30 seconds of 30-cm PEEP). The size of the thyroid gland, the duration of operation, hospital stay, and drain usage were reported. Postoperational occurrences of drainage, hematoma, reoperation, and additional complications were compared between the groups. Valsalva maneuver application helped to identify minor bleeding points in 32% of the cases. There was no significant difference between the study groups regarding the thyroid gland size, operation duration, hospital stay, and the duration of drain usage (P > 0.05 for all). The amount of drainage as well as the frequencies of hematoma, reoperation, and further complications was not significantly different between the study groups (P > 0.05 for all). Intraoperative application of Valsalva maneuver is only useful to detect minor bleeding points in some patients during thyroidectomy operations, but it had no effect on the duration of postoperative drain usage, the amount of drainage, and risk of hematoma. Therefore, intraoperative application of Valsalva maneuver has no beneficial effect on postoperative hemorrhagic complication after thyroidectomy operations.

Hemorrhoidectomy in Patients with Grade III or IV Disease: Harmonic Scalpel Compared With Conventional Closed Technique.

Abstract Background : Harmonic scalpel (Ultracision) is a device that simultaneously cuts and coagulates soft tissues through ultrasonic vibration. In this study we aimed to determine the operative and postoperative characteristics of hemorrhoidectomy using the harmonic scalpel compared with the conventional closed technique. Methods and Findings: Patients with grade III or IV hemorrhoids, operated between 2010 and 2013, using the harmonic scalpel (n=21) or the conventional closed technique (n=42) were included in the study. Exclusion criteria were thrombosed or strangulated hemorrhoids, concomitant perianal disease, history of recurrent perianal surgery and known tendency for bleeding. Patient characteristics, duration of operation, complications, postoperative pain measured on a visual analog scale (VAS), hospital stay, and return to regular activity were compared between the two groups retrospectively. Patient characteristics (female:male ratio, mean age, hemorrhoid grade, and symptom duration) were similar between the two groups. Harmonic scalpel and conventional hemorrhoidectomy patients did not differ significantly in terms of VAS score of pain, complications, hospital stay or return to regular activity. However, duration of operation was significantly shorter with harmonic scalpel (24.2 vs. 36.2 min, p<0.05 ). Conclusion: There is no clear evidence to support the routine use of harmonic scalpel system in hemorrhoid surgery.
