Prognostic Indices of Poor Nutritional Status and Their Impact on Prolonged Hospital Stay in a Greek University Hospital

Background. To ascertain the potential contributors to nutritional risk manifestation and to disclose the factors exerting a negative impact on hospital length of stay (LOS), by means of poor nutritional status, in a nonselected hospitalized population. Materials and Methods. NutritionDay project questionnaires were applied to 295 adult patients. Study parameters included anthropometric data, demographics, medical history, dietary-related factors, and self-perception of health status. Body Mass Index (BMI) and Malnutrition Universal Screening Tool (MUST) were calculated for each participant. MUST score was applied for malnutrition assessment, while hospital LOS constituted the outcome of interest. Results. Of the total cohort, 42.3% were at nutritional risk and 21.4% malnourished. Age, gender, BMI, MUST score, autonomy, health quality, appetite, quantity of food intake, weight loss, arm or calf perimeter (P < 0.001, for all), and dietary type (P < 0.01) affected nutritional status. Poor nutrition status (P = 0.000), deteriorated appetite (P = 0.000) or food intake (P = 0.025), limited autonomy (P = 0.013), artificial nutrition (P = 0.012), weight loss (P = 0.010), and arm circumference <21 cm (P = 0.007) were the most powerful predictors of hospital LOS >7 days. Conclusion. Nutritional status and nutrition-related parameters such as weight loss, quantity of food intake, appetite, arm circumference, dietary type, and extent of dependence confer considerable prognostic value regarding hospital LOS in acute care setting.

Acute appendicitis secondary to Enterobius vermicularis infection in a middle-aged man: a case report.

IntroductionAcute appendicitis due to Enterobius vermicularis is very rare, affecting mostly children. Whether pinworms cause inflammation of the appendix or just appendiceal colic has been a matter of controversy.Case presentationA Caucasian 52-year-old man was referred to our Emergency Department with acute abdominal pain in his right lower quadrant. The physical and laboratory examination revealed right iliac fossa tenderness and leukocytosis with neutrophilia. An open appendectomy was performed. The pathological examination showed the lumen containing pinworms. Two oral doses of mebendazole were administered postoperatively. The follow-up to date was without incident and he was free of symptoms one year after the operation.ConclusionThe finding of E. vermicularis in appendectomy pathological specimens is infrequent. Parasitic infections rarely cause acute appendicitis, especially in adults.One should keep in mind that the clinical signs of intestinal parasite infection may mimic acute appendicitis, although rare. A careful evaluation of symptoms such as pruritus ani, or eosinophilia on laboratory examination, could prevent unnecessary appendectomies.

Cecal obstruction due to primary intestinal tuberculosis: a case series

IntroductionPrimary intestinal tuberculosis is a rare variant of tuberculosis. The preferred treatment is usually pharmaceutical, but surgery may be required for complicated cases.Case presentationWe report two cases of primary intestinal tuberculosis where the initial diagnosis was wrong, with colonic cancer suggested in the first case and a Crohns disease complication in the second. Both of our patients were Caucasians of Greek nationality. In the first case (a 60-year-old man), a right hemicolectomy was performed. In the second case (a 26-year-old man), excision was impossible due to the local conditions and peritoneal implantations. Histopathology revealed an inflammatory mass of tuberculous origin in the first case. In the second, cell culture and polymerase chain reaction tests revealed Mycobacterium tuberculosis. Both patients were given anti-tuberculosis therapy and their post-operative follow-up was uneventful.ConclusionsGastrointestinal tuberculosis still appears sporadically and should be considered in the differential diagnosis along with other conditions of the bowel. The use of immunosuppressants and new pharmaceutical agents can change the prevalence of tuberculosis.

Concurrent appendiceal and umbilical endometriosis: a case report and review of the literature

IntroductionEndometriosis affects 3 to 10 percent of women of reproductive age. Most of the time it involves the pelvis; however, sites of endometriosis have been reported almost anywhere in the body. Appendiceal and primary umbilical endometriosis are considered rare loci, making accurate diagnosis elusive. Here we present the case of a 46-year-old woman with concurrent appendiceal and umbilical endometriosis.Case presentationA 46-year-old Greek woman presented with a large mass in the lower abdomen adhering to the surrounding organs. She reported recurrent lower abdominal and pelvic pain and the presence of a dark-blue hard nodule at the umbilicus. She had no previous medical, surgical or gynecological history. Her physical examination and laboratory test results were without any significant findings. The laparotomy revealed a fibromatose uterus adhering to the rectum and a urinary cyst and a palpable mass in the vermiform appendix. A hysterectomy and an appendectomy were performed. The umbilical mass was also excised. Pathology revealed endometriosis of the umbilicus and the appendix. The postoperative period was uneventful and she was discharged.ConclusionsEndometriosis, although rare, should always be considered in women of reproductive age, presenting with cyclic pain. The diagnosis is, most of the time, difficult and requires a high degree of clinical suspicion. The clinical doctor should be aware that endometriosis can sometimes be multifocal, thus a thorough investigation is required in all cases.

Desmoid tumor of mesentery in familial adenomatous polyposis: a case report

Our case concerns a 52-year-old male with FAP, who was treated surgically by restorative colectomy and ileal pouch anal anastomosis. Three years later, he presented with acute epigastric pain and obstructive ileum. While a mass in the left lateral abdominal region was palpated. The patient underwent laparotomy, some adhesions were dissected and biopsies were taken from the mass. Pathological examination revealed a desmoid tumor of the mesentery.

Condylomata acuminata within perianal fistulae tracts: report of two cases

The commonest sights of appearance of condylomata acuminata are in the genital and anal regions. Herein we present two cases of condylomata within perianal fistulae tracts, resulting in recurrence in one case and a malignant-like tumour in the second. To our knowledge, these are the first cases reported in the literature.

PARATHYROID FUNCTION AFTER TOTAL THYROIDECTOMY: A RANDOMIZED CLINICAL TRIAL CONCERNING THE INFLUENCE OF THE SURGICAL TECHNIQUE

OBJECTIVE Thyroidectomy impairs parathyroid function, even if it does not necessarily lead to postoperative clinical hypocalcemia. This study was prospective and evaluated the parathyroid hormone (PTH) function in nonclinically symptomatic patients after total thyroidectomy performed by two different techniques. METHODS Prospective randomized clinical trial including 269 patients undergoing classic or harmonic scalpel total thyroidectomy. Pre-operatively and at 48 hours, biochemical analysis was performed. Simultaneously, a sodium bicarbonate test (SBT) was performed. RESULTS Calcium and PTH were altered for both groups ( P<.001). During SBT at 3 minutes after infusion, PTH rose and reached its maximum for both groups ( P<.001) and then decreased at 5 minutes ( P<.001 and P = .004) and at 10 minutes ( P = .006 and P = .043) before returning to baseline levels. At 5 and 10 minutes of the SBT, some differences were observed between the groups. The difference in clinically obvious parathyroid dysfunction between groups was not significant, but there was a difference in the peak PTH levels after bicarbonate stimulation. Similarly, total secretion during the test, as well as total secretion for the first 10 minutes, was practically the same for the two groups. Additionally, partial subclinical postoperative hypoparathyroidism was clearly more common in the harmonic scalpel thyroidectomy group ( P<.001). CONCLUSION SBT demonstrated more impairment in the harmonic scalpel group, as parathyroid function was altered after thyroidectomy. ABBREVIATIONS HSTT = harmonic scalpel total thyroidectomy PTH = parathyroid hormone SBIT = sodium bicarbonate infusion test.
