Prediction of cytology-histology discrepancy when Bethesda cytology reports benign results for thyroid nodules in women: with special emphasis on pregnancy.

Objectives: Benign category of Bethesda classification is generally well known to carry a false-negative rate of 0-3%. The current study was designed to investigate the rate of false-negative cytology in patients who underwent thyroidectomy for presumably benign thyroid diseases. Predictive risk factors for false results and malignancy were evaluated along with cytology-histology discrepant cases.Materials and methods: Females who underwent thyroidectomy between May 2014 and December 2022 were included. Demographics, ultrasound (US) features, fine-needle aspiration (FNA) diagnosis, surgical indications and outcomes, final histology reports, risk factors, and malignancy rate were recorded. Cytology-histology discrepant cases were further evaluated for interpretation errors and risk factors. Statistical analyses were performed using Fisher's exact and Mann-Whitney U tests.Results: Of 581 women with a benign thyroid disease who underwent thyroidectomy, 91 was diagnosed as incidental carcinoma (15.6%) and most was T1a (4.9 ± 2.7 mm, 95.6%). Final histology reports revealed mostly papillary carcinoma (93.4%). Predictors of malignancy such as age, family history, previous radiation exposure, and iodine-deficient diet did not help in risk stratification (p > 0.05, for each). However, FNA taken during pregnancy was determined as a risk factor (n = 7, 7.6%, p < 0.05) since it may cause a delay in diagnosis. Cytology-histology discrepant cases were seen to be mostly due to sampling errors (45%, p < 0.05), followed by misinterpretations (37.3%, p < 0.05). There was no reason for discrepancy in 17.5%, and this was linked to inherent nature of thyroid nodule with overlapping cytologic features. Best identifiable risk factor for misinterpretation was pregnancy as well (n = 5, 14.7%, p < 0.05).Conclusions: Risk of malignancy in a presumably benign thyroid disease should not be ignored. Radiology-cytology correlation by an experienced dedicated team may help in decreasing sampling errors. Physiologic changes caused by pregnancy may shade malignant transformation in thyrocytes, and it would be appropriate to be cautious about benign FNA taken during this period.

Nerve-preserving Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy for Advanced Primary Caecal Cancer Invading Pelvic Side-wall: Report of a Case With Right Leg Limping.

Radical surgery to achieve optimal cytoreduction in locally advanced caecal cancer may dictate femoral or sciatic nerve resection, especially in cases with pelvic side-wall involvement. In such a situation, gait disturbance is inevitable. A 61-year male with a new-onset right leg limping due to locally advanced right colon carcinoma underwent cytoreductive surgery (CRS) with partial resection of right pelvic side- wall, and hyperthermic intraperitoneal chemotherapy (HIPEC). During the operation, we aimed to preserve both the sciatic and femoral nerves to prevent further deterioration of his right leg limping postoperatively. However, we did not compromise the principles of radical surgery and all tumoral implants around femoral vessels and nerves were removed. Completeness of cytoreduction score was zero (CC0). The resection of all macroscopic disease is the main goal of CRS, but as seen in our case with tumor-related walking difficulty, nerve-sparing CRS and HIPEC may prevent further deterioration of the situation. Key Words: Cytoreductive surgery, Hyperthermic intraperitoneal chemotherapy, Sciatic nerve, Femoral nerve, Caecal cancer.

The effect of intraoperative autofluorescence monitoring on unintentional parathyroid gland excision rates and postoperative PTH concentrations-a single-blind randomized-controlled trial.

PURPOSE: Intraoperative imaging of parathyroid glands (PGs) has been developed in order to reduce the risk of unintentional parathyroidectomy during total thyroidectomy. This novel modality is based on their intrinsic characteristic of autofluorescence (AF) after near-infrared light exposure. The aim of this study was to assess the effect of this method on the risk of unintentional PG excision (total or partial) during total thyroidectomy. METHODS: This was a single-blind, randomized-controlled trial including adult patients who underwent scheduled total thyroidectomy between December 2019 and March 2020. These patients were randomly allocated to two groups: one in which near-infrared autofluorescence imaging (NIRAF) was applied (NIR group) and one without NIRAF (NONIR group). Hormonal and biochemical assessment was performed pre- and 24-h postoperatively. AF findings and the number of PGs autotransplanted were recorded. RESULTS: One-hundred and eighty patients were eligible. Unintentional (total or partial) PG excision rates during total thyroidectomy in the NONIR (n = 90) and NIR (n = 90) groups were 28.9% [95% confidence interval (CI) 19.8-39.4%] and 14.4% (95% CI 7.7-22.1%), respectively (p = 0.02). Furthermore, NIR reduced the risk of parathyroid tissue presence in the specimen sent for pathology (relative risk 0.51, 95% CI 0.28-0.92; p = 0.02). However, the number of PGs identified by NIR could not predict the risk of postoperative hypoparthyroidism. CONCLUSIONS: NIRAF imaging during total thyroidectomy led to a significant reduction in PG excision rates. However, this modality did not result in the reduction of postoperative hypoparathyroidism or hypocalcemia risk.

A fast and effective solution for ingrown toenail: Creation of a 2-mm space between tissue and nail by sutureless lateral longitudinal excision.

Nails have both functional and aesthetic importance. Undertreatments cause frequent recurrences affecting its functionality, while over-treatment spoils the aesthetic view. To describe the most practical and aesthetic method to treat ingrown toenail. All patients with ingrown toenail who applied to outpatient clinics of General Surgery Department between 2013 and 2019 were enrolled. A 2-mm space between tissue and nail by lateral longitudinal excision was created with only minimal matricectomy, under local anaesthesia. A total of 2334 surgical procedures were performed in 2118 patients. Recurrence rate was 1.7% during 36-month follow-up, most (70.7%) in younger men (22 years). The location of the lesions (right/left, medial/lateral or bilateral) did not show difference (p > 0.05 for each). Predisposing factors were tight-fitting footwear (4.5%), incorrect nail-trimming (3%), genetic tendency (2.8%), obesity (2.1%) and trauma (0.75%); but each was p > 0.05. Mean operation time was 3 min. There was no important complication, except hematoma (0.89%) and infection (0.68%). Mean healing time was 10 days and patients returned to daily activities in 3 days. Longitudinal excision with minimal matricectomy technique provides all dead tissue and diseased parts of nail and soft tissue to be removed. It is simple, cost-effective, satisfactory and aesthetic.

Conservative management of 154 patients with idiopathic granulomatous mastitis: Simple is better?

PURPOSE: Both the aetiology and treatment of idiopathic granulomatous mastitis (IGM) is controversial and unnecessary resections can lead to over-treatment in such a benign disease. Our aim was to report our experience in patients with IGM managed mainly with conservative methods, such as antibiotics, drainages and corticosteroids. MATERIAL AND METHODS: Pathology database from 2008 to 2018 was reviewed retrospectively. Demographics and symptoms were documented from patient charts. Follow-up information was obtained from clinical reviews, and severity and duration of symptoms were documented. All data were transferred to Excel file and the parameters were compared. RESULTS: All 154 patients were women. Mean age was 35.9 years. Empiric broad-spectrum antibiotic, abscess drainage and steroid treatments were seen to be successful in most of the cases (95.4%). In patients with limited regression (2.5%) or persistant lesions (1.9%), a second cycle was employed with a total regression rate of 100%. Recurrence was seen one or two times in 23 (14.9%) and 2 (1.2%) patients in a mean follow-up period of 5.3 years. The average time of recurrence was 2.5 years (range, 9-74 months). CONCLUSIONS: Conservative management could be efficacious for IGM, and less and simpler can be enough to achieve more effective results. KEY WORDS: Abscess drainage, Antibiotics Idiopathic granulomatous mastitis (IGM), Conservative management, Corticosteroids.

Risk factors for complications after endoscopic retrograde cholangiopancreatography A referral Center experience.

AIM: Endoscopic retrograde cholangiopancreatography (ERCP) is an important diagnostic and therapeutic tool in patients with hepato-pancreatobiliary diseases. In the present study, we sought to determine predictors of post-ERCP complications at our institution. METHODS: A retrospective analysis of patients who underwent ERCP in between January 2010 and November 2011 was done. Demographics, indications, ERCP findings, success rate, complications and the need of repeat procedure were evaluated with special emphasis on the difficulty in cannulation procedure, the primary etiology of the disease (benign/malign) and age. Chi-square analysis was applied for statistical analysis. The differences were considered statistically significant, if the p value was less than 0.05. RESULTS: A total of 112 ERCP was performed in 81 patients. Thirty-eight were male (46.9 %) and 43 were female (53.1%). Mean age was 61.3 (range 17-88), and 31 patients was seventy years and older (38.3 %). Complications were detected in 28 patients (34.6 %). Nine cases with difficult or unsuccessful cannulation (69.2 %) had complications (p=0.001). Patients with benign diseases showed less complications (21/70), in comparison with those with malignancies (7/11) (30 % vs. 63.6 %, respectively; p<0.05). Complication rate in patients 70 years and older was 32.2 % (n=10) compared to 35.3 % in patients younger than 70 (n= 18) (p<0.05). CONCLUSION: Risk factors such as difficult or incomplete cannulation and malignancy are considered as possible predisposing factors for complications. Age is an independent factor. KEY WORDS: Endoscopic cholangiopancreatography, Risk factors.

Serum paraoxonase (a high-density lipoprotein-associated lipophilic antioxidant) activity in clinical follow-up of patients with acute pancreatitis, with particular emphasis on oxidative stress parameters and lipid profile: a prospective pilot trial.

The purpose of this study was to investigate the possible role of PON-1, an antioxidant lipophilic enzyme linked to HDL-C (high-density lipoprotein cholesterol), on the pathophysiology and clinical follow-up of acute pancreatitis. Biochemical tests, PON-1 and oxidative stress parameters (malonyl dialdehyde, MDA; superoxide dismutase, SOD; total antioxidant capacity, TAC) were evaluated in the sera of patients with acute pancreatitis at admission (day 0), day 3 and day 10 of follow-up, between June and September 2017. SPSS 13.0 statistical software package programme was used for statistical analyses.Mean age was 51.4 of the total 25 patients. Ranson scores were 0-1 points (60%), 3-4 points (24%) and 5-6 points (16%). CTSI (computed tomography severity index) scores were calculated, and most of the patients were seen to have mild or average pancreatitis (96%). While total cholesterol, triacylglycerol and LDL-C (low-density lipoprotein) levels stayed in their normal limits, there was a significant decrement tendency. HDL-C level was seen to rise significantly above its upper limit at day 10 (p < 0.001). Mean PON-1 levels were measured as 69.23, 76.72 vs. 113.15 U/mL at days 0, 3 and 10, respectively; and it was positively correlated with HDL-C (p < 0.001). Serum SOD increased also in parallel with PON-1 (20.49 vs. 39.46 U/mL) while MDA level decreased significantly (3.9 vs. 2.28 µM, p < 0.001). TAC was seen to rise significantly after treatment (0.52 vs. 1.22 mM). In conclusion, decreased PON-1 and HDL-C together with antioxidants SOD and TAC at the early period of acute pancreatitis were seen to rise after treatment, while the previously higher MDA level decreased in parallel. This reveals the importance of the balance between oxidative stress and antioxidant defense mechanisms in clinical progression of the disease, and the potential of PON-1 as a promising clinical marker.

Fournier's gangrene: A retrospective analysis of 25 patients.

BACKGROUND: Fournier's gangrene is a surgical emergency that progresses rapidly and insidiously and results in high morbidity and mortality rates unless it is immediately diagnosed and managed. Here we analyze the outcomes of patients who were followed up and treated for Fournier's gangrene. METHODS: We conducted a retrospective analysis of the medical data of 25 patients operated on for Fournier's gangrene between January 2010 and June 2015. The diagnosis of Fournier's gangrene was made by performing a physical examination. Patients who had genital, perineal, and perianal tenderness; induration; cyanosis; gangrene; and subcutaneous crepitation were considered as having Fournier's gangrene. Following resuscitation, aggressive surgical debridement was performed and vacuum-assisted closure (VAC) was conducted in addition to debridement in select patient. Repeat debridements were performed as requirement. RESULTS: This study included 25 patients. Fourteen patients (56%) were females and 11 (44%) were males. The mean age of the patients was 54.3 years (range: 27-82 years). The mean duration of hospital stay was 21.4 days; the mean number of debridements performed was 2.4. Thirteen patients (52%) had perianal abscesses, and 20 (80%) had diabetes mellitus. All patients underwent extensive debridement; 16 patients (64%) underwent VAC in addition to debridement. Patients undergoing VAC had significantly longer durations of hospital stay and a higher mean number of debridements performed (p=0.004 and p=0.048, respectively). An ostomy was made in one patient, and one patient died. CONCLUSION: In Fournier's gangrene, early diagnosis, effective resuscitation, aggressive debridement, and VAC application in suitable cases may reduce the morbidity and mortality rates and the need for an ostomy.

Importance of diagnostic laparoscopy in the assessment of the diaphragm after left thoracoabdominal stab wound: A prospective cohort study.

BACKGROUND: Stab wounds in the left thoracoabdominal region may cause diaphragmatic injury. The aim of the present study was to determine incidence of diaphragmatic injury and role of diagnostic laparoscopy in detection of injury in patients with left thoracoabdominal stab wound. METHODS: Total of 81 patients (75 male, 6 female; mean age 27.5±9.8 years; range 14 to 60 years) who presented with left thoracoabdominal stab wound between April 2009 and September 2014 were evaluated. Laparotomy was performed on patients who had hemodynamic instability, signs of peritonitis, or organ evisceration. Remaining patients were followed conservatively. After 48 hours, diagnostic laparoscopy was performed on patients without laparotomy indication to examine the left diaphragm for injury. Follow-up and treatment findings were prospectively evaluated. RESULTS: Thirteen patients underwent laparotomy while diagnostic laparoscopy was performed on remaining 68 patients. Left diaphragmatic injury was observed in 19 patients (23.5%) in the study group. Four injuries were diagnosed by laparotomy and 15 were diagnosed by laparoscopy. Presence of hemopneumothorax did not yield difference in incidence of diaphragmatic injury (p=0.131). No significant difference was detected in terms of diaphragmatic injury with respect to entry site of stab wound in the thoracoabdominal region (p=0.929). CONCLUSION: It is important to evaluate the diaphragm in left thoracoabdominal stab injuries, and diagnostic laparoscopy is still the safest and most feasible method.

Thiamin and folic acid deficiency accompanied by resistant electrolyte imbalance in the re-feeding syndrome in an elderly patient.

INTRODUCTION: Re-feeding Syndrome (RS) is a deadly complication, which can be encountered during "refeeding" of malnourished patients. In these patients, thiamin deficiency may develop and "risk awareness" is the most significant factor in the management of these patients. In this case report, the treatment is presented of an elderly patient who was diagnosed with RS and followed-up in the intensive care unit (ICU) due to resistant fluidelectrolyte imbalance. CASE: An 87-year-old elderly woman was admitted to the hospital due to aspiration pneumonia. On day 4, during parenteral nutrition (30 kcal/kg/day), severe electrolyte imbalance developed. Total parenteral nutrition (TPN) was stopped, and enteral feeding together with potassium (90 mmol/day, i.v.) were started. During follow-up, plasma potassium values remained less than 3 mmol/L. Despite replacement therapy, hypoalbuminemia, hypomagnesemia, hypocalcemia, and hypophosphatemia persisted. Considering the parenteral nutrition (30 kcal/kg/day) during the hospitalization period, a diagnosis of RS was made. On day 10, thiamin (200 mg/day, i.v.) and folic acid (5 mg/day) were added, and the patient subsequently responded to electrolyte replacement treatment. The patient was discharged on day26 with a home-care plan. CONCLUSION: In patients with malnutrition, thiamin replacement should be given before starting nutrition to prevent RS. Energy intake should be 10kcal/kg/day at the start, and be gradually increased between days 4-10. Hemodynamic-laboratory parameters should be closely monitored. All these measures may be life-saving for patients at high risk.

Evaluation of diaphragm in penetrating left thoracoabdominal stab injuries: The role of multislice computed tomography.

INTRODUCTION: Penetrating left thoracoabdominal stab injuries are accompanied by diaphragmatic injury in 25-30% of cases, about 30% of which later develop into diaphragmatic hernia. This study aimed to determine the role of multislice computed tomography in the evaluation of left diaphragm in patients with penetrating left thoracoabdominal stab wounds. MATERIALS AND METHODS: This study reviewed penetrating left thoracoabdominal stab injuries managed in our clinic between April 2009 and September 2014. The thoracoabdominal region was defined as the region between the sternum, fourth intercostal space, and arcus costa anteriorly and the vertebra, lower tip of scapula, and the curve of the last rib posteriorly. Unstable cases and cases with signs of peritonitis were operated with laparotomy; the remaining patients were closely monitored. Forty-eight hours later, a diagnostic laparoscopy was applied to evaluate the left hemidiaphragma in asymptomatic patients who did not need laparotomy. The preoperatively obtained multislice thoracoabdominal computed tomography images were retrospectively examined for the presence of left diaphragm injury. Then, operative and tomographic findings were compared. RESULTS: This study included a total of 43 patients, 39 (91%) males and 4 (9%) females of mean age 30 years (range 15-61 years). Thirty patients had normal tomography results, whereas 13 had left diaphragmatic injuries. An injury to the left diaphragm was detected during the operation in 9 (1 in laparotomy and 8 in diagnostic laparoscopy) of 13 patients with positive tomography for left diaphragmatic injury and 2 (in diagnostic laparoscopy) of 30 patients with negative tomography. Multislice tomography had a sensitivity of 82% (95% CI: 48-98%), a specificity of 88% (71-96%), a positive predictive value of 69% (39-91%), and a negative predictive value of 93% (78-99%) for detection of diaphragmatic injury in penetrating left thoracoabdominal stab injury. CONCLUSIONS: Although diagnostic laparoscopy is the gold standard for diaphragmatic examination in patients with penetrating left thoracoabdominal stab wounds, multislice computed tomography is also valuable for detecting diaphragmatic injury.

Biliopancreatic duct injection of ethanol as an experimental model of acute and chronic pancreatitis in rats.

In the present study, we described an easily reproducable experimental pancreatits model induced by biliopancreatic duct injection of ethyl alcohol. Seventy Wistar albino rats were divided equally into seven groups randomly: the control group (group 1), acute pancreatitis groups; induced by 20% ethanol (group 2), 48% ethanol (group 3), 80% ethanol (group 4), chronic pancreatitis groups; induced by 20% ethanol (group 5), 48% ethanol (group 6) and by 80% ethanol (group 7). Acute pancreatitis groups were sacrified on postoperative day 3, while the control group and chronic pancreatitis groups were killed on postoperative day 7. Histopathologic evaluation was done, and P < 0.05 was accepted as statistically significant. All rats in group 3 developed acute pancreatitis (100%). Inflammatory infiltration of neutrophils and mononuclear cells, interstitial edema, and focal necrotic areas were seen in the pancreatic tissues. Similarly, all rats in group 6 developed chronic pancreatitis (100%). Interstitial fibrosis, lymphotic infiltration, ductal dilatation, acinar cell atrophy, periductal hyperplasia were seen in the pancreatic tissues. Mortality was seen only in group 7. The biliopancreatic ductal injection of 48% ethanol induced acute and chronic pancreatitis has 100% success rate.

Paraoxonase and arylesterase activities, lipid profile, and oxidative damage in experimental ischemic colitis model.

Objective. In the present study, since PON1 is known as an HDL-associated antioxidant enzyme that inhibits the oxidative modification of LDL and oxidative stress plays a role in the pathogenesis of mesenteric ischemia, we investigated the changes in PON1 activity and lipid profile in an experimental ischemic colitis model. Methods. Forty male Wistar albino rats were divided into two groups: the control group (N = 15) and the experimental group (N = 25). All animals were anesthetized with ether and ketamine anesthesia to undergo a midline laparotomy. Ischemic colitis was induced by marginal vessel ligation in the splenic flexura (devascularization process). A sham laparotomy was performed in the control group. All animals were sacrificed on the seventh postoperative day. Oxidative stress marker (malonyldialdehyde, MDA), lipid profile, and paraoxonase (PON-1) and arylesterase activities were determined. Histopathological evaluation was done under light microscopy, after sectioning and staining with hematoxyline and eosin. Statistical analysis was conducted using Student's t-test and Mann-Whitney U test, and P < 0.05 was considered as statistically significant. Results. There was a significant decrease in both serum and tissue PON1 activity in ischemic colitis group (P < 0.01, for each). Similarly, arylesterase levels showed a parallel decrease in both tissue and serum of the experimental group (P < 0.01 and P < 0.001, retrospectively). MDA, an oxidative stress marker, was seen to increase in the experimental group (P < 0.01, tissue; P < 0.05, serum). In experimental group, there was a significant rise in serum total cholesterol and LDL levels (P < 0.001, for each). However, HDL level decreased significantly (P < 0.001). Triglycerides did not show any change between the groups (P > 0.05). Conclusions. PON1 and arylesterase play an important role in the pathophysiology of ischemic colitis.

Delivery in female kidney transplant recipients with hepatitis C virus infection: is it safe for mother and newborn?

The aim of this report is to evaluate whether pregnancy is a risk factor for poor outcome of infection with hepatitis C virus or for allograft deterioration among kidney transplant recipients. The first case was in a 41-year-old pregnant kidney transplant recipient with hypercreatinemia and a history of toxic hepatitis. The second case was treated with interferon before transplant. Tacrolimus-based immunosuppressive regimens were used during the pregnancies. Hypertension complicated both pregnancies, and the pregnancies ended with cesarean delivery at preterm and term with healthy but low-weight newborns. The first patient became positive for hepatitis C virus RNA after pregnancy without a flare in transaminase level. Antibodies to hepatitis C virus were negative in the newborns. In conclusion, pregnancy should be promoted for kidney recipients infected with hepatitis C virus who have stable graft and liver function.

Abdominal wall endometriosis in the cesarean section surgical scar: a potential diagnostic pitfall.

AIM: The abdominal wall is an uncommon site of extrapelvic endometriosis. It usually develops in a previous surgical scar and should be considered in the differential diagnosis of any abdominal swelling. Classical symptoms of endometriosis may resemble abdominal wall lesions such as an incisional hernia, hematoma, granuloma, abscess or various soft tissue tumors; therefore, a definitive preoperative diagnosis is not always easy to determine in every case. The aim of this article is to review the clinical findings, imaging results and histopathology of those of our patients who have had cesarean scar endometriosis. METHODS: Patients diagnosed with abdominal wall endometriosis in their surgical scars from February 2008 to March 2010 were documented. The age, parity, symptoms, previous surgeries, initial diagnosis, diagnostic modalities, definitive operation, postoperative complications, histopathological evaluations and recurrences were recorded and analyzed. RESULTS: There were 18 patients with a mean age of 34.5 ± 9.6 years. All (100%) had a gradually growing nodular abdominal mass in or adjacent to their cesarean incision scars. This was often associated with pain (83.3%), either noncyclical (26.6%) or cyclical (73.3%) in nature. Ultrasonography (100%), computerized tomography with intravenous contrast (22.2%) and/or magnetic resonance imaging (66.6%) were performed on the patients. All patients underwent surgery and their masses were completely excised. The mean diameter of the removed masses was 3.9 ± 1.4 cm. The final pathological diagnosis for each case was abdominal wall endometriosis. Biannual follow-up examinations for two years revealed that each patient had a complete and uneventful recovery without recurrence. CONCLUSION: Abdominal wall endometriosis should be considered in the differential diagnosis of masses located at cesarean section incision scars, which should be excised for definitive diagnosis and treatment.

Granulomatous mastitis: is it an autoimmune disease? Diagnostic and therapeutic dilemmas.

PURPOSE: Granulomatous mastitis (GM) is a rare benign inflammatory breast disease. The clinical presentation of granulomatous mastitis usually mimics malignancy or infection. The aim of this study was to review the clinical and diagnostic features of GM and discuss the medical and surgical treatment of our series of eight GM patients. METHODS: Between 2008 and 2010, eight patients were diagnosed with GM and underwent surgery. Patients were evaluated clinically and radiologically. The diagnosis of GM was confirmed in all cases by core needle or excisional biopsies. Serological tests were performed for rheumatoid factor (RF), antinuclear antibody (ANA), and anti-double-stranded DNA (anti-dsDNA). RESULTS: The mean patient age was 37 years. Common presenting symptoms were a hard mass, pain, inflamed hyperemic skin, and sinus formation. Serological tests for RF were positive in 6 patients, and ANA and anti-dsDNA antibodies were detected in 2 patients. All patients underwent antibiotic therapy before surgery, and were treated with wide surgical excision with negative margins. Methylprednisolone (16 mg/day for 3 months) therapy was used in 3 patients (all RF and 2 ANA/anti-dsDNA positive) following a wide excisional biopsy after a postoperative recurrence mimicking skin lesions was seen. These patients responded well to steroid therapy. CONCLUSIONS: The diagnosis of GM should be made carefully to avoid a misdiagnosis. Steroid therapy should be considered based on the idea that this is an autoimmune disease.

Ramsay Hunt syndrome with atypical progress in a renal transplant recipient: a case report.

Ramsay Hunt syndrome is a rare complication of herpes zoster disease in which reactivation of latent varicella zoster virus infection occurs in the geniculate ganglion causing otalgia, unilateral vesicular eruption in a restricted dermatomal distribution, and peripheral facial paralysis. Dermal infections caused by human pathogenic herpes viruses are common in organ transplant recipients. For a transplant surgeon, it is imperative to remember that viral prophylaxis is essential in the follow-up of the transplant patients. Here, we presented a case of renal transplant and Ramsay Hunt syndrome with multiple cranial nerve involvement, with an atypical course. Management and differential diagnosis of this particular case are discussed with a review of the literature.

Liver transplant for mixed capillary-cavernous hemangioma masquerading as hepatocellular carcinoma in a patient with hepatocellular carcinoma.

Hemangioma is the most common benign tumor of the liver. Unlike cavernous hemangioma, hepatic capillary or mixed capillary-cavernous hemangioma is a rare type of tumor in adults. Clinical presentation of hemangioma may mimic that of hepatocellular carcinoma. Furthermore, radiologic features on computed tomography and magnetic resonance imaging may not be typical for hemangioma and can be confused with hepatocellular carcinoma. Symptomatic hemangiomas require some form of treatment, such as corticosteroids, interferon, radiation, arterial embolization, surgical resection, or liver transplant. In the present case study, we present a patient treated with liver transplant for hemangioma mimicking hepatocellular carcinoma. This case report illustrates the atypical imaging appearance of hemangioma and possible confusion it can cause in diagnosing hepatocellular carcinoma, especially in a hepatitis C carrier.

Acute abdomen in pregnancy requiring surgical management: a 20-case series.

OBJECTIVES: The obstetrician often has a difficult task in diagnosing and managing the acute abdomen in pregnancy. A reluctance to operate during pregnancy adds unnecessary delay, which may increase morbidity for both mother and fetus. In this study, we present our experience in pregnant patients with acute abdomen. STUDY DESIGN: Pregnant patients with acute abdomen requiring surgical exploration were enrolled from 2007 to 2010. Demographics, gestational age, symptoms, fetal loss, preterm delivery, imaging studies, operative results, postoperative complications and histopathologic evaluations were recorded. Ultrasound (US) and magnetic resonance (MR) imaging studies were evaluated. Data analyses were performed with Microsoft Excel and statistical evaluations were done by using Student's t-test. RESULTS: There were 20 patients with a mean age of 32 years. The rate of emergency surgery was seen to be significantly higher in the second trimester (p<0.05). Most common symptoms were abdominal pain (100%) and nausea (80%). US was done in all patients while MR imaging was used in 30%. However, US findings were consistent with surgical findings in only 55%, while MR was successful in assigning the correct diagnosis in 83.3%. Appendicitis and adhesive small bowel obstruction were the most common etiologies causing acute abdomen (30% and 15%, respectively). All patients tolerated surgery well, and postoperative complications included wound infection, 10%, preterm labor, 5%, and prolonged paralytic ileus, 5%. One patient died from advanced gastric carcinoma and the only fetal death was seen in this case. CONCLUSIONS: Prompt diagnosis and appropriate therapy are crucial in pregnant with acute abdomen. The use of US may be limited and CT is not desirable due to fetal irradiation. MR has thus become increasingly popular in the evaluation of such patients. Adhesive small bowel obstruction should be kept in mind as an important etiology.
