Demography evaluates the traits of human populations mainly by measuring their sizes and fluctuations. Due to their features, the archeological population structures refer to the distribution of people based both on sex and age at death. These parameters have a direct impact on the risk of death because they vary significantly with age and sex and this is reflected in a proportional sharing of deaths in several groups at risk. This chapter deals with the demographic structure of several imperial communities scattered through the roman Suburbium. A whole sample of almost 3500 skeletons pertaining to 12 necropolis has been analyzed in order to determine the gender and the age at death. Each necropolis is contextualized according to information about people lifestyle and health, trying to deepen our knowledge on the death risk exposure for every population. Our results suggest to consider the imperial Suburbiumn population as a very complex landscape, where several communities were featured by their different way to face the socio-economic and biologic environments.

Paleogenetics is providing increasing evidence about the biological characteristics of ancient populations. This paper examines the guiding principles and methodologies to the study of ancient DNA with constant references to the state of the art in this fascinating disciplin.

Primitive NHL represents 9% of testis tumours and the 85% is diagnosed in patient older thant 60 years old. Usually pain and a testis mass are the main manifestations. The Authors report the case of a 82 years-old man with bilateral hydrocele causing severe alteration in the deambulation. The cytology did not show blood cells or neoplastic cell in the FNAB. The US showed a complete modification in the testis. The patient underwent to surgery intervention of vaginalis tunic eversion and resection with the aim of control the symptoms. The histology on multiple biopsy of testis and epidydims bilaterally showed a large B-cell lymphoma. The patient was treated with 6 chemotheray cycles (Rituximab, Vincristine, Cyclophosphamide, Prednisone). Bilateral hydrocele is a rare clinical presentation of testis NHL. In this patient, blood and neoplastic cell absence in the cytology made difficult the differential diagnosis between inflammatory pathology and neoplasia. Hystopathologic study and immunologic pattern can make a certain diagnosis.

Introduction: Mesh infection in inguinal herniography is usually caused by Staphilococcus aureus and Staphilcoccus epidermidis. Generally it obliges to prosthesis removal with hernia relapse and increase of social costs for the prolongation of hospitalization., Case Report: A 60-year-old woman, obese, undergone 4 months before to left inguinal prosthetic herniorrhaphy complicated by infection of the surgical site which didn't require the explantation of the mesh, although determining an early hernia relapse. She is submitted by the authors to a surgical intervention for left groin hernia relapse with placement of a polypropylene monofilament fixed with prolene. Six hours after the operation she shows systemic symptoms and local signs of prosthesis infection. Cultural examination of the surgical wound secretion allows the identification of Streptococcus dysgalactiae subspecies equisimilis (SDSE). A therapy with Amoxicillin-Clavulanic Acid and Levofloxacine leads to resolution, in 10 weeks, of the infection., Discussion: In our case the infection of the new mesh, appearing prematurely, has been probably favoured by obesity and operative time longer than 3 hours. Conservative treatment has been fulfilled by success for the elevated sensitivity of the SDSE bacterium to penicillin and fluoroquinolones., Conclusions: Recent epidemiologic studies have demonstrated an increase of infections caused by SDSE, which will probably gain clinical relevance in the next future relatively to surgical prosthetic hernioplasty. In all cases of infection the authors suggest cultural isolation of the casual germ and the execution of the antibiogram because the conservative medical treatment can avoid mesh removal with consequent elevated risk of hernia relapse.

Introduction: Gallbladder polypoid lesions occur in 1.3%-6.9% of cases. The preoperative diagnosis between benign, malignant and potentially malignant lesions is difficult. Therefore it is not possible any., Patients and Methods: The Authors describe three cases. The case 1 was a gallbladder diffuse adenomyomatosis; the ultrasound and the CT were of little help in defining preoperatively the nature and the gravity of the thickening. Case 2 was an adenomyomatosis of the fundus: the ultrasound examinations were not able to establish preoperatively lesion's nature, site and dimensions. In the case 3, ultrasounds showed polypoid lesions and calculi concrections not found in colecistectomy., Discussion: The ultrasound is the most widely used diagnostic tool in the evaluation of gallbladder polypoid lesions; its accuracy is only 66%. CT, which has an accuracy level of 75%, must be carried out there is any possibility of malignant degeneration of the polyp. If doubts persist, a MR, 93% accuracy, is indicated. In selected cases, PET can be of further help., Conclusions: The preoperative diagnosis of the nature of gallbladder polypoid lesions is "difficult" and this justifies the lack of consensus on treatment. However, the adenoma-carcinoma sequence, widely discussed in literature, can justifies to the use of CT, MR, PET and surgical treatment after an ultrasound examination.

Introduction: Splenic infarction is a rare cause of acute abdomen. It must be suspected in patient with hematologic diseases or thromboembolic conditions. The most common onset symptom is left-upper quadrant abdominal pain. Additional symptoms include fever and anemia. Laboratory may show elevated white blood cell and platelet counts., Case Report: A 97-year-old female with a past history of atrial fibrillation presented with left-upper quadrant abdominal pain and fever since 20 days. Laboratory showed elevated white blood cell and platelet counts, increased C-reactive protein and lactate dehydrogenase. Both ultrasonographic and tomographic scans showed a large hypodense area of the spleen. The patient received intravenous antibiotic therapy, which led to significant clinical improvement with discharge 16 days after admission., Discussion: The diagnosis of splenic infarction is based both on clinical presentation and imaging studies. Angio-computed tomography is the diagnostic procedure of choice. Ultrasonography and conventional radiology are useful in the differential diagnosis with other abdominal and thoracic diseases mimicking splenic infarction. In our case the management was conservative, because the patient was hemodynamically stable and antibiotic therapy could control the sepsis. Moreover, advanced age and poor cardiac and respiratory conditions contraindicated surgery., Conclusions: In our case splenic infarction was probably due to a thromboembolic event secondary to atrial fibrillation. In accordance with the literature, we suggest initial conservative therapy. Surgery is indicated only in the presence of complications.

Introduction: Gallstone ileus is a rare complication of cholecystolithiasis. It causes 1-3% of the mechanical obstructions of the small bowel. It often affects patients between 63 and 85 years old. Pre-operative diagnosis is usually delayed 1-10 days because there is not a specific symptomatology., Case Report: The authors report the case of a 50 year-old man with diagnosis of mechanical obstruction of the small bowel caused by a voluminous gallstone. Ileal occlusion was showed by CT. The patient underwent to one-stage emergency surgery with enterolithotomy, cholecystectomy and duodenal fistula repair. Patient's recovery was regular and he was discharged fourteen days after surgery., Discussion: In our case gallstone ileus was diagnosed with a delay of 5 days. Ultrasonography was not able to show the gallbladder. Diagnosis was made by CT, which is the diagnostic gold standard., Conclusion: Patient's performance status influences surgical strategy. In our experience, the patient underwent one-stage surgery because he was considered at low risk. Instead staged procedure with enterolithotomy and delayed cholecystectomy and fistula repair, is performed only in patients at high risk.

Umbilical primary endometrioma is a rare extra-uterine localization of endometriosis with a documented neoplastic risk. It is often difficult to distinguish primary umbilical endometriosis from other benign and malignant tumors of the abdominal wall. The Authors report a case of umbilical endometriosis in a 36-year old female. Endometriosis was suspected because of the presence of the typical cyclic bleeding and swelling. Abdominal CT excluded the presence of other endometriotic localizations. The umbilical mass was widely excised together with umbilicus, fascia and peritoneum. The tissue defect was primary closed without prosthetic mesh. Histological examination of the specimen showed the presence of endometrial glands with stromal component, compatible with the diagnosis of endometriosis. The Authors suggest that surgery should be performed in the first 3-4 days of the follicular phase, to minimize the risk of diffusion of endometriotic cells. Moreover, the excision should be wide in order to prevent local recurrence.

Unlabelled: Abdominal blunt trauma is the main cause of death in people younger than 40 years old. The liver injury still represents a challenging problem. Isolated hepatic injury is rare and it occurs more frequentely in polytraumatizated patients and causes massive haemoperitoneum. The Authors report a case of a 83 years-old woman admitted to Emergency Department for syncope due to an active bleeding arising from a rupture of a right hepatic lobe unsuspected tumor. The computer tomography (CT) scans showed a clear pattern of liver laceration of the VI segment with contrast enhancement spreading in the surrounding tissues, and detected a multifocal hepatocarcinoma located in the VI, VII and VIII segments. Patient's haemodinamically unstable conditions suggested an urgent laparotomy. An accurate perihepatic packing with sterile-drape were successfully employed to control liver hemorrage. Temporary abdominal closure, followed by hepatic arteriography and the right hepatic artery embolization, completed the damage control. Re-exploration laparotomy after 72 hours confirmed the definitive haemostasis and the pack removal was performed without complications., Conclusions: CT plays a leading role in the diagnosis of liver damage. The patient's haemodynamic status is the principal criterion determining conservative or operative therapy in blunt liver injury. The early perihepatic packing followed by artheriographic embolization to stop liver hemorrhage showed efficacy and safety for the patient. The packing performed with sterile-drape is able to avoid removal complications and 72 hours timing for the pack removal is effective to avoid re-bleeding.

Hepatocellular carcinoma (HCC) is the most common malignancy of the liver and the third most common cause of cancer mortality worldwide. The major risk of developing HCC is associated with HBV and HCV hepatitis. Liver transplant (LT) is the gold standard for "small" HCC (HCCs) in Child-Pugh class A cirrhotic patients. However its use has been restricted by the severe shortage of donors, so that hepatic resection (HR) is often performed in these patients. In the last two decades image-guided interventional catheterization and ablative regional treatment procedures have revolutionized the therapy of unresectable primary and secondary liver tumors. The Authors present a case of a 61-years old man with Child-Pugh class A HCCs. The age and the previous history of bladder carcinoma made the patient not suitable for LT. The patient refused HR so that transarterial chemoembolization combined to thermo-ablation therapy and oral intake of tamoxifen were proposed. Patient's tolerance to the treatments has been good. During 11-year follow-up there was earlier intrahepatic progression of the tumor followed by reduction in size and number of the lesions. In spite of the scarce prognosis, chemoembolization and immunotherapy allowed to achieve a satisfactory local control of disease in our patient and guaranteed a good quality of life at long-term follow-up.

Uterine carcinosarcoma is a highly aggressive neoplasm with tendency to early recurrence and/or metastasis. The neoplasia has both epithelial and stromal malignant components. Clinically, it is characterized by a postmenopausal metrorrhagia, associated sometimes with abdominal pain. The Authors describe a case of carcinosarcoma in a 82-year old woman with a vaginal bleeding since 10 months and an ingravescent hypochromic anemia. The RMN of the abdomen and pelvis showed a mass occupying the whole uterine lumen, without signs of pelvic diffusion. A bilateral hystero-oophorectomy was performed; the patient's critical conditions and a high anaesthesiological risk advised us not to perform a bilateral pelvic lymphadenectomy with aortic sampling. Six months after operation, a clinical follow-up with a total-body CT didn't show any sign of local recurrence and/or distant metastasis. From the analysis of this case report and from the data of the literature some important considerations can be done: a) gynecologic check up in post-menopausal women with associated risk factors (obesity and hypertension) can allow an early diagnosis also in asymptomatic patients; b) sovrapubic and transvaginal US, abdomino-pelvic CT and MRI are essential for a correct clinical staging; c) surgical excision followed by the histological examination of the specimen is mandatory to establish a correct diagnosis.

The Authors report a rare case of a 57 years old man affected by a left radial nerve schwannoma that occurred as an asymptomatic lesion of the axilla. At clinical examination the lump was undistinguishable from the most common axillary lymphadenopathy. A lymphoadenopathy was erroneously diagnosed with ultrasonography (US). This mistake was due to the low specificity of the instrumental methodology and to the rarity of an asymptomatic schwannoma of the infraclavicular brachial plexus. The neoplasia was excised without using the microscope. In the early post-operative follow up, a "falling" attitude of the wrist, the hand and the fingers appeared, peculiar for a lesion of the radial nerve. Furthermore a hypoaesthesia of the skin of first finger and of the first interosseus space was associated. The sensitive and motor electromyography showed a radial nerve suffering. The "stupor" of the nerve trunk was treated with steroid therapy for 7 days and the patient underwent to some series of neuro-rehabilitative physical therapy for 12 weeks. The postoperative total body CT, showed that the lesion was unique: therefore it was possible to exclude the diagnosis of neurofibromatosis. After 28 months electromyography and axillary US were performed showing the complete resolution of the motor and sensitive deficit and the absence of local recurrence.

Diverticular disease is very frequent in Western countries; in 5% of the cases it is the cause of serious bleeding, haemodynamic instability and death. The authors report a case of 74 years old patient with severe lower gastrointestinal bleeding. She was in antiplatelet treatment with acetylsalicylic acid (100 mg/die) and clopidogrel (75 mg/die) for preventing the restenosis of medicated stents positioned to treat an acute coronary syndrome. At the same time the patient was under treatment for primary hypercholesterolemia with rosuvastatin (20 mg/die). The severe haemorrhage demanded haemodynamic stabilization, achieved by colloid infusion and blood transfusions. The bleeding continued; selective arteriography showed it's origin from the areas of the sigmoid and superior hemorrhoidal arteries. During the procedure, embolization of the inferior mesenteric artery using spiral type BALT was performed, with consequent bleeding interruption. Fifteen days after the embolization, a rectosigmoid colonoscopy showed a sigmoid diverticular disease. The treatment with acetylsalicylic acid and clopidogrel has surely contributed to the severity of the hemorrhage. Recent experimental and clinical evidence suggests a possible antiplatelet effect of the statins.

The relations between oral disease and living conditions and health of a population are important to reconstruct the biological status of a population. The incidence of caries was considered by the calculation of frequencies for individual and for tooth but also by the estimate of index of caries et extraction in four Roman imperials necropolis. The analysis indicates a general increase in carious affection in mesio-distal direction, and mandibular teeth seem to be lesser affected than maxillary ones. The comparison among the necropolis seem to confirm a different socio-economic organization: sub-urban contexts probably had a simple carbohydrates rich diet and this may have encouraged the growth of carious injuries. Conversely the lower frequency of caries in Vallerano, probably associated to small farming communities, could be attributed to a diet with an highest protein/carbohydrate. In both contexts, however, the degree of dental hygiene was a significant cause of caries.

One of the goals of the anthropological research of the Anthropological Service of the Archaeological Superintendence of Rome is to reconstruct the hygienic-environmental living conditions of the ancient populations in Imperial Age. We considered some not specific pointers of stress in four necropolis, that are excavated in the last years in the Suburbium. In particular Harris's lines, porotic hyperostosis and enamel hypoplasia are been considered. Two shape of research have been lead: (a) an analysis of the frequencies of the three factors on the data from a single necropolis and (b) a comparison between enamel hypoplasia and porotic hyperostosis. The distributions of such alterations indicates the presence of light stresses.
