RESUMO
Background/aim: A number of tumor markers detected in the serum or pathological specimens using immunohistochemical methods are used for early detection of malignancies and postoperative follow-up. Human leukocyte antigen-G (HLA-G) is a nonclassic HLA class I molecule. Recent studies suggested a relationship between HLA-G positivity and the stage or the phenotype of the malignancy. In this study, the relationship between serum HLA-G positivity and thyroid cancer was investigated. Materials and methods: Fifty patients with thyroid cancer and 45 healthy volunteers were included in this study. Serum HLA-G levels were measured using ELISA. Results: HLA-G was positive in only 3 out of 50 patients with thyroid cancer (2 papillary, 1 follicular type). On the other hand, HLA-G was positive in 20 out of 45 healthy subjects (P < 0.001). The prevalence of detectable levels of serum HLA-G was independent of sex and age in the whole study population. No correlation was found between serum HLA-G value and thyroid hormone profile, neither in papillary thyroid cancer nor follicular thyroid cancer patients. Conclusion: In this study, serum HLA-G was significantly less common in patients with thyroid cancer than in healthy controls.
RESUMO
Background/aim: Idiopathic granulomatous mastitis (IGM) is a rare, chronic inflammatory disease of the breast. Erythema nodosum (EN) is a rare extramammary manifestation of IGM. The purpose of this study is to determine the clinical and demographic characteristics of 11 IGM and EN patients and to evaluate the efficacy of methylprednisolone treatment. Materials and methods: In our series, ten patients had EN bilaterally, whereas one patient had a lesion of the right pretibial area. The mean age of the patients was 35.5 years (range: 29-45 years). IGM and EN were diagnosed by the necessary serological, microbiological, radiological, and histopathological examination. After diagnosis, methylprednisolone was started in the first week at 0.8 mg/kg daily for treatment. The weekly dose was tapered to 0.1 mg/kg daily over 8 weeks.Results: We started with the treatment of methylprednisolone, and in all our cases the initial response was excellent. In 2 weeks the IGM symptoms had markedly declined, while signs of EN disappeared completely. Patients were followed for an average of 60 months after treatment. None of the 11 patients had recurrence.Conclusion: We herein report a rare series considering IGM cases complicated by EN. Few such cases have been reported in the literature. We advocate for an initial trial of methylprednisolone treatment, which proved to be very successful in our patients.
RESUMO
Background/aim: Primary thyroid lymphoma (PTL) is a very rare thyroid malignancy. It should be diagnosed and treated immediately and accurately. Our aim was to evaluate the diagnostic methods and treatment results for patients with PTL.Materials and methods: We retrospectively evaluated the records of 11 patients with PTL from 2009 to 2015, diagnosed at our institute. Age, sex, stage, histopathologic type, presence of Hashimoto's thyroiditis, diagnostic methods, treatment types, and recurrence were examined.Results: Six patients were female, 5 were male, and the median age of the patients was 61 years (range: 15-76 years). All patients had a large palpable mass in the neck. Fine needle aspirate (FNA) biopsy was performed in all patients; however, it was useful only in the diagnosis of 7 patients. Excisional and surgical biopsy was performed in 4 patients. All patients had non-Hodgkin B-cell lymphoma, including 9 cases of diffuse large B-cell lymphoma (DLBCL), and 2 patients had mucosa-associated lymphoid tissue (MALT) lymphoma. Recurrence was observed in one patient. Median survival was 34 months.Conclusions: The preferred option for the diagnosis of PTL should be FNA biopsy, and the treatment should be decided on according to whether the disease is limited to the thyroid gland or not, its histological type, and its stage.
RESUMO
PURPOSE: Thyroglobulin (Tg) assessment in the needle washout after fine-needle aspiration biopsy (FNAB) of a suspicious neck lymph node (LN) is known to improve the diagnostic accuracy in patients with papillary thyroid cancer (PTC). However, there is still controversy on the best diagnostic cut-off levels for FNAB-Tg and whether thyroglobulin antibody (TgAb) positivity affects FNAB-Tg. The objectives of this study were to determine (i) the diagnostic power of different cut-offs for FNAB-Tg and (ii) if serum TgAb(+) negatively affects the FNAB-Tg evaluation. METHODS: This was a retrospective cohort study analyzing PTC patients with suspicious neck LNs, in a university hospital setting, from October 2009 to October 2013. In total, 103 patients with PTC (226 LNs) undergoing ultrasound-guided FNAB for LNs were included. Cytology and FNAB-Tg levels were compared in reference to LN histopathology and the effect of TgAb(+) on FNAB-Tg levels was evaluated. RESULTS: The diagnostic accuracies of FNAB-Tg cut-off of 1 and 10 ng/mL were 94.1% and 88.2%, respectively. Raising the cut-off from 1 to 10 ng/mL led to decreased sensitivity rates (91.9% vs. 83.9%). The receiver operating characteristic curve analysis demonstrated that the best FNAB-Tg cut-off was 1.2 ng/mL. There were no LNs with an FNAB-Tg ≥ 10 ng/mL that turned out to be cytologically or histopathologically benign. FNAB-Tg levels of the histopathologically malignant LNs were similar between TgAb (+) and TgAb (-) patients (p = 0.546). Serum Tg predicted FNAB-Tg levels above 1 ng/mL (p = 0.002) and FNAB-Tg predicted malignant histopathology (p = 0.004), both independently of the TgAb status of the patient. CONCLUSIONS: FNAB-Tg ≥ 1 ng/mL has a superior diagnostic power, irrespective of TgAb (+), in PTC patients with suspected LN involvement.

INTRODUCTION: Monitoring LDL-C levels is essential in clinical practice because there is a direct relation between low-density lipoprotein cholesterol (LDL-C) levels and atherosclerotic heart disease risk. Therefore, measurement or estimate of LDL-C is critical. The present study aims to evaluate Artificial Intelligence (AI) and Explainable AI (XAI) methodologies in predicting LDL-C levels while emphasizing the interpretability of these predictions. MATERIALS AND METHODS: We retrospectively reviewed data from the Laboratory Information System (LIS) of Ankara Etlik City Hospital (AECH). We included 60.217 patients with standard lipid profiles (total cholesterol [TC], high-density lipoprotein cholesterol, and triglycerides) paired with same-day direct LDL-C results. AI methodologies, such as Gradient Boosting (GB), Random Forests (RF), Support Vector Machines (SVM), and Decision Trees (DT), were used to predict LDL-C and compared directly measured and calculated LDL-C with formulas. XAI techniques such as Shapley additive annotation (SHAP) and locally interpretable model-agnostic explanation (LIME) were used to interpret AI models and improve their explainability. RESULTS: Predicted LDL-C values using AI, especially RF or GB, showed a stronger correlation with direct measurement LDL-C values than calculated LDL-C values with formulas. TC was shown to be the most influential factor in LDL-C prediction using SHAP and LIME. The agreement between the treatment groups based on NCEP ATPIII guidelines according to measured LDL-C and the LDL-C groups obtained with AI was higher than that obtained with formulas. CONCLUSIONS: It can be concluded that AI is not only a reliable method but also an explainable method for LDL-C estimation and classification.

Idiopathic granulomatous mastitis (IGM) is a benign, chronic inflammatory lesion of the breast. Immunoglobulin G4 (IgG4) associated disease is rare in the breast. In our study, we aimed to evaluate the efficacy of steroid treatment on IgG4 levels in tissue in patients diagnosed with IGM. Between 2008 and 2017, 55 patients diagnosed with IGM in our clinic were included in the study. Demographic, clinical, microbiologic and histopathologic characteristics, treatment modality and recovery time were evaluated retrospectively. Patients were divided into 3 groups according to tissue IgG4 levels: negative (Group I), infrequently and slightly positive (Group II), and highly positive (Group III). Group I patients had a complete response rate of 77.8%. In the rest of the patients (22.2%), insufficient response was detected from the beginning of the treatment. In Group II, the response rate was 91.3% and the permanent success rate after treatment was 87.0%. Although group III patients had a complete response at the beginning (95.65%), they relapsed in a short period of time (26.1%) after discontinuation of steroid treatment. At least one steroid-related side effect was observed in 47 (85.8%) patients in all groups. There is no consensus on the dose and duration of immunosuppressive treatment in IGM. In this study, responses to steroid treatment according to IgG4 concentration in pathologic breast tissue and recurrences after the end of treatment were determined. We think that high IgG4 concentration in the tissue is associated with recurrence and other immunosuppressive drugs should be added as maintenance after steroid treatment.

INTRODUCTION: The choice of treatment for rectal cancer often differs in older and younger patients, with the rate of radiotherapy use lower among older adults. In our daily practice, when evaluating a frail older patient with rectal cancer, we usually choose to give less treatment. This may be due to concern that the patient will not be able to tolerate radiotherapy. The Geriatric 8 score (G8GS) is a guide to evaluating treatment tolerability as it relates to frailty in older adults with cancer. The aim of this study was to evaluate treatment outcomes and tolerability in older patients with rectal cancer treated with radiotherapy (RT) accompanied by G8GS. MATERIALS AND METHODS: Patients aged 65 and older with stage I-III rectal adenocarcinoma who were treated with RT and had a G8 evaluation were included in this multicenter retrospective study. Prognostic factors related to G8GS were calculated using Chi-square and logistic regression tests and survival rates were calculated by the Kaplan-Meier test using the SPSS v24.0 software. All p-values ≤0.05 were considered statistically significant. RESULTS: A total of 699 patients from 16 national institutions were evaluated. The median age was 72 years (range 65-96), and the median follow-up was 43 (range 1-190) months. Four hundred and fifty patients (64%) were categorized as frail with G8GS ≤14 points. Frail patients had higher ages (p = 0.001) and more comorbidities (p = 0.001). Ability to receive concomitant and/or adjuvant chemotherapy rates were significantly higher in fit patients (p = 0.002 and p = 0.001, respectively). No significant difference was observed in terms of grade 3-4 early and late toxicity for both groups. Cancer-related death was higher (p = 0.003), and 5- and 8-year survival rates were significantly lower (p = 0.001), in the frail group. Age and being frail were significantly associated with survival. DISCUSSION: Radiotherapy is a tolerable and effective treatment option for older adults with rectal cancer even with low G8GS. Being in the frail group according to G8GS and having multiple comorbidities was negatively associated with survival. Addressing the medical needs of frail patients through a comprehensive geriatric assessment prior to radiotherapy may improve G8GS, allowing for standard treatment and increased survival rates.

Objectives: Ultrasonography and fine-needle aspiration biopsy (FNAB) are the gold standard methods in the prediction of benign and malignant thyroid nodules. However, despite being easily applicable, FNAB is an invasive procedure. Less invasive biomarkers should be utilized in the diagnosis of thyroid malignancies. In this study, we aimed to determine the parameters that can be used in the diagnosis of differentiated thyroid cancer (DTC) based on the serum thyroid and thyroglobulin (TG) levels which are routinely checked in patients followed up for thyroid nodules. Methods: In the study, we evaluated patients who underwent thyroid surgery for nodular diseases between January 2015 and June 2022. Of the 1444 patients evaluated, 919 patients who met the inclusion criteria (normothyroid benign nodular disease or normothyroid DTC) were included in the study. Patients were divided into two groups as benign group (BG) and DTC group (DTCG). We compared patients' pre-operative serum thyroid and TG values and the diagnostic properties of their ratios. Results: Of the 919 patients included, 517 (56.3%) were in BG and 402 (43.7%) were in DTCG. In DTCG, 318 patients were female and 84 patients were male. The mean age in the DTCG was 47.8 years. Comparison of DTCG and BG revealed a significant difference between T3/T4 ratio (p=0.002), T3/TSH ratio (p≤0.001), T4/TSH ratio (p≤0.001), TG/TSH ratio (p≤0.001), and TSH/TG ratio (p≤0.001). However, evaluation of the specified values by ROC analysis showed that the T3/T4 ratio did not make a significant difference between the two groups (p=0.1), whereas the other values displayed a significant difference (p≤0.001 for T3/TSH, p=0.001 for T4/TSH, p≤0.001 for TG/TSH, and p<0.001 for TSH/TG). Conclusion: T3/TSH (cutoff =2.183), T4/TSH (cutoff=0.6), and TG/TSH (cutoff=29.67) values were found to be significant tumor markers for the prediction of malignancy in thyroid nodules, and low values were found to be associated with malignancy. TSH/TG (cutoff=0.031) value was also significant in predicting malignancy while high values were found to be associated with malignancy. Thyroid hormone and TG ratios may alter the preferred treatment method for thyroid nodules.
RESUMO
PURPOSE: Lichtenstein repair has been the gold standard in inguinal hernia surgery. The aim of this study was to investigate the role of mesh fixation in terms of postsurgical chronic pain and recurrence. METHODS: Sixty patients with primary inguinal hernias were treated between March 2007 and December 2008. Thirty patients underwent conventional Lichtenstein repair while a self-adhesive mesh was used for the second group. The primary outcome parameters were the rate of recurrence and chronic pain. The operating time, postoperative pain, complications, and time when patients returned to work were recorded. RESULTS: Fifty-one patients completed the survey. Early pain scores were lower in the self-adhesive mesh group. The main advantage of the self-adhesive mesh was the shorter operating time (23.70 ± 5.57 vs 36.90 ± 11.36, P = 0.006). Both techniques were almost identical in terms of long-term chronic pain (P = 0.294), and the rates of recurrence at the end of a median of 31 months' follow-up were identical. CONCLUSION: Self-adhesive mesh repair of inguinal hernias is superior to the conventional Lichtenstein method in terms of shorter operative time and less pain in the early postoperative period. The rates of chronic pain and recurrence are similar with the suture-fixed repairs.

PURPOSE: Pilonidal sinus disease (PSD) is usually seen on the sacrococcygeal region in adolescent patients. The current study analyzed the outcome of the rhomboid excision and the Limberg flap procedure (cLF) in comparison to the modified Limberg flap procedure (mlF) for PSD. METHODS: Four hundred and sixteen patients with PSD were operated on under spinal or general anesthesia by cLF and mlF. The patients were divided into two groups. In Group 1, cLF was performed on 211 patients. In Group 2, mlF was performed on 205 patients. RESULTS: No significant difference was detected between Groups 1 and 2 in terms of sex, age, preoperative disease period, follow-up time, the mean hospital stay, and hypoesthesia. The mlF group had better clinical results than the cLF group. The recurrence rate was statistically higher in the cLF group 1 than in the mlF group (P = 0.036). The time to return to work, time to walk without pain, and time to be able to sit on the toilet without pain were longer in the cLF group (P = 0.001). The maceration and wound infection rate were statistically higher in the cLF group than in the mlF group (P = 0.020 and P = 0.019, respectively). CONCLUSION: The mlF is a more effective treatment than cLF for the surgical management of PSD.

BACKGROUND: Phyllodes tumor (PT) is a rare neoplasm comprising less than 1% of all breast tumors. Its clinical spectrum ranges from a benign and locally recurrent form of behavior to malignant and metastatic forms. The aim of the study was to evaluate the clinical characteristics, treatment regimens, survival and late complications in patients with PT. PATIENTS AND METHODS: We retrospectively reviewed the medical records of 10 women who were treated for PT in our center between 1998 and 2002. All cases were histologically examined by an experienced breast pathologist, and tumors were classified as benign, borderline malignant or malignant according to standard histological criteria. RESULTS: The median age at diagnosis was 45.5 years (range: 21-69 years). Seven (70%) of 10 tumors were benign and 3 (30%) were malignant. The median tumor size was 29 mm (range: 12-80 mm). The least safe margin was 1 cm. Three of 10 patients had malignant PT and underwent simple mastectomy. Local recurrence was determined in no patients. Only one patient had lung metastasis. Median follow-up period was 62 months (range, 12-96 months). The patient with lung metastasis was treated with doxorubicine but died one year after the operation. CONCLUSION: PT is a rare neoplasm of the breast. It resembles fibroadenoma. Local excision with appropriate surgical margins seems adequate in all patients (Tab. 1, Fig. 3, Ref. 15).

Breast ductoscope is a fiberoptic endoscope used for examining the distal breast ducts under direct vision in order to identify the source of pathologic nipple discharge. The purpose of this study was to investigate the reliability of intra-operative breast ductoscopy in patients with pathologic nipple discharge, which could not be identified by radiologic tests. Between April 2002 and March 2007, breast ductoscopy was performed in 34 patients who had pathologic nipple discharge with no radiologic evidence about the source. The procedures were carried out under general anesthesia and ductoscopic findings were as well as the histopathology of the specimens were recorded and documented. In 88%, (30 of 34) of the patients, endoscope was successfully introduced into the external orifice of the ducts at the nipple and proximal breast ducts were successfully visualized. Ductoscopy revealed intraductal lesions (i.e., ductal obstruction, intraductal papilloma, red patches, and erythematoid platter) in 20 patients (66%). Among the 20 patients with visible endoluminal pathology, nine had a papilloma and eight had signs of either acute inflammation (bleeding, erythema) or previous inflammation with healing (adhesions and blocked ducts). In two cases, invasive breast carcinoma was identified, one of which was ductal carcinoma in situ (DCIS) with minimal invasion. In both cases, there had been blocked ducts. In one case DCIS was identified. Breast ductoscopy is a reliable and easy-to-use method to demonstrate the source of pathologic nipple discharge in cases with bleeding and other intraductal lesions.

BACKGROUND: The purpose of this study is to compare the complications of different types of thyroidectomy for benign and malignant thyroidal diseases. METHODS: Between January 2001 and March 2006, 982 patients underwent thyroidectomy in single institute. A retrospective analysis was performed on demographic characteristics and pathology reports of patients, complications of surgery as well as the follow-up of patients. Sixty patients could not be fully followed up and were excluded. RESULTS: The types of the surgical procedures were as follows; 451 (48.9%) total, 137 (14.9%) subtotal, 60 (6.5%) near-total thyroidectomy and 274 (29.8%) lobectomy with isthmectomy. In the benign group, temporary recurrent laryngeal nerve injury (RLNI) was the most common complication in patients with toxic diffuse goiter (TDG 2%) while this complication occurred in patients with differentiated thyroid cancer (DTC 1.5%) in the malign group. Permanent RLNI in benign thyroidal diseases was seen more commonly in patients with toxic multinodular goiter (1.3%). In benign thyroidal diseases, temporary hypoparathyroidism (THPT) was mostly found in patients with TDG (8%), whereas in malignant thyroidal diseases this was found more in patients with DTC (2%). Permanent HPT (PHPT) in benign thyroidal diseases was observed more commonly in patients with multinodular goiter (0.9%). In malignant thyroidal diseases, it was more frequently observed in patients with DTC (0.5%). Infective complications after thyroid surgery are rarely observed and have a low incidence (0.4%). CONCLUSION: RLNI and HPT are the most common complications of after thyroid surgery but they may be avoided with an accurate technique (Tab. 3, Ref. 15). Full Text (Free, PDF) www.bmj.sk.

BACKGROUND: Acute mesenteric ischemia is an entity characterized by rapid developing of circulatory failure. Reperfusion following ischemia causes further mucosal injury. METHODS: In our study, an experimental model of 15 minutes of reperfusion following 45 minutes of superior mesenteric artery occlusion was established. The segments which underwent I/R injury were histopathologically examined, and blood samples obtained from the heart were analyzed for alkaline phosphatase and creatine kinase levels. RESULTS: The results of the study demonstrated that mucosal injury in anandamide injected group was less expressed than in other groups suggesting that anandamide might have a protective effect on the mucosa. After L-NAME and indomethacin injection, the protective effect of anandamide seems to disappear due to inhibition of NO and prostaglandins. The results of histopathological examination of specimens from CB1 receptor and anandamide injected group indicate that I/R injury has regressed. CONCLUSION: The protective effect of endogenous anandamide on I/R injury may take place through CB2 receptors in the small intestine; NO and prostaglandin, which are activated through the stimulation of CB2 receptors may be responsible for this protective effect (Fig. 8, Ref. 29).

AIM: The objective of this study was to compare the dual phase MIBI scinitgraphy with MIBI and Tc-99m pertechnetate (MIBI + Tc-99m) study in defining the parathyroid adenomas, and to evaluate the effect of histologic and biochemical characteristics on the imaging of parathyroid adenomas with Tc-99m methoxyisobutylisonitrile (MIBI) scintigraphy. METHODS: Thirty-six patients with parathyroid adenomas were studied prospectively. All patients were evaluated with both MIBI and (MIBI + Tc-99m) study. MIBI uptake of adenomas correlated with oxyphill, chief cell and tumour weight of the surgically excised glands. MIBI uptake was also compared with serum calcium (Ca), phosphorus (P) and intact parathormone (iPTH) levels. RESULTS: A total of 38 parathyroid adenomas were surgically excised from 36 patients. MIBI + Tc-99m identified 35 of the parathyroid lesions (92%). Whereas, MIBI study detected 30 of the 38 parathyroid adenomas (79% sensitivity) (p=0.0001). There were no false positives. Adenoma weight showed significiant correlation with MIBI uptake (p=0.001). Oxyphyill cell content also showed high correlation with MIBI uptake. Delayed images showed better correlation than the early views (Early MIBI p=0.033; Delayed MIBI; p=0.001). CONCLUSION: MIBI + Tc-99m pertechnetate interpretation is more sensitive than only dual MIBI imaging for the detection of parathyroid adenoma. Oxyphill cell content and weight of the lesions proved to be important determinants of 99mTc-MIBI accumulation in parathyroid adenoma. We found no significant correlation between MIBI accumulation, Ca, P and iPTH serum levels (Tab. 2, Fig. 2, Ref. 15). Full Text (Free, PDF) www.bmj.sk.

BACKGROUND: Benign schwannomas, also referred to as neurilemomas, neurinomas, and perineural fibroblastomas, are encapsulated nerve sheath tumors. Primary schwannomas of the liver are extremely rare. We present a case of liver schwannoma, incidentally found in a patient with breast cancer. CASE: A 66-year-old female consulted her physician for a mass she palpated on her left breast. The abdominal ultrasonography (USG) revealed a 44 x 28 mm mass in the medial segment of the left lobe of her liver suspicious of a metastasis. An USG-guided biopsy was performed and the histo-pathological examination revealed a "peripheral nerve sheath tumor". Positron emission tomography (PET-CT) revealed a pathologic FDG uptake in the lesion that was previously defined in the liver. The tumor resected from the liver was 5 x 4 x 3 cm, yellowish, soft, and capsulated tumor. Microscopic examination revealed that the mass consisted of bundles of spindle cells with hypercellular and hypocellular areas. In immunohistochemistry, there was a strong positive staining for S-100. The tumor was diagnosed as benign liver schwannoma. CONCLUSION: Schwannomas are benign, encapsulated neoplasms. Symptoms and signs vary depending on the anatomical site and the size of the neoplasm; however, most schwannomas present as an asymptomatic or painless mass. Recurrence is unusual, despite of an incomplete removal, and malignant transformation is exceedingly rare (Fig. 4, Ref. 8). Full Text (Free, PDF) www.bmj.sk.

AIM: To investigate the roles of the adipocytokines, ghrelin and leptin in gastric cancer cachexia. METHODS: Resistin, ghrelin, leptin, adiponectin, insulin and insulin-like growth factor (IGF-I), were measured in 30 healthy subjects, and 60 gastric cancer patients of which 30 suffered from cancer-induced cachexia and 30 served as a control group. The relationships between hormones, body mass index (BMI) loss ratio, age, gender, and Glasgow Prognostic Score (GPS) were investigated. RESULTS: Cachexia patients had higher tumor stage and GPS when compared with non-cachexia patients (P < 0.05). Ghrelin, resistin, leptin, adiponectin and IGF-I, showed a significant correlation with BMI loss ratio and GPS (P < 0.05). A strong correlation was seen between GPS and BMI loss (R = -0.570, P < 0.0001). Multivariate analysis indicated that BMI loss was significantly independent as a predictor of ghrelin, resistin, leptin and IGF-I (P < 0.05). Existence of an important significant relationship between resistin and insulin resistance was also noted. CONCLUSION: These results showed that serum ghrelin, leptin, adiponectin, and IGF-I play important roles in cachexia-related gastric cancers. No relationship was found between resistin and cancer cachexia. Also, because of the correlation between these parameters and GPS, these parameters might be used as a predictor factor.

Meckel diverticulum (MD) is the most common congenital anomaly of the gastrointestinal tract that is generally asymptomatic and only manifests in a specific way when complications exist. An unusual complication of MD is known as Littre hernia. It comprises less than 1% of all MD. Littre hernia is the protrusion of an MD through a potential abdominal opening. Usual sites of Littre hernia are right inguinal (50% of cases), umbilical hernia (20%), and femoral hernia (20%). We report a case of Littre hernia in a boy who presented with acute scrotal pain and swelling.

Diaphragmatic rupture occurs in 0.8% to 3.6% of patients after blunt or penetrating thoracoabdominal trauma, and the preoperative diagnosis is difficult. The diagnosis of traumatic diaphragmatic rupture may be made on initial presentation or at any time later. Right-sided diaphragmatic rupture is rare and occurs in approximately 5% to 20% of all diaphragmatic disruptions. The incidence of herniation of the intra-abdominal organs into the pleural cavity is also low, observed in only about 19% of right-sided diaphragmatic ruptures. We present a case of right-sided traumatic rupture of the diaphragm diagnosed 15 years after the initial blunt trauma. A 22-year-old male patient fell 15 years before and was symptom-free since then. He was referred to our hospital with the signs of herniation of the right diaphragm, which was manifested in the chest x-rays. The definite diagnosis was made through thoracoabdominal computed tomography. The diaphragmatic rupture was repaired via abdominal approach.

Lightning strike is an unusual form of trauma in terms of being one of the leading causes of death from natural phenomenon. Lightning strike can cause severe damage to many systems and results in a high mortality. The most common cause of death in the lightning strike victim is cardiopulmonary arrest. The most vulnerable subjects for lightning strike are individuals who work in open fields, farmers, and swimmers. The cardiac and neurological injuries are the most serious injuries. Burns, tinnitus, blindness, and secondary blunt trauma have also been reported. Gastrointestinal complications have been documented very rarely. In this study, we present a case of gastric perforation after lightning strike. No report related to gastric perforation caused by lightning strike has been identified in the literature.
