Bilateral synchronous testicular torsion: a case report

A man presented to the emergency room with testicular pain and swelling. Bilateral synchronous testicular torsion was diagnosed and treated. Physical and radiographic findings are discussed as well as differential diagnosis. Avoiding the confusion between torsion and epididymitis with the help of the nuclear scan is stressed.     

Bilateral elastofibroma: a case report and review of the literature

Elastofibroma, or elastofibroma dorsi as it was first described, is an uncommon tumor-like process that characteristically appears as an ill-defined mass in the infrascapular region of elderly patients. This lesion can occur bilaterally and may appear asynchronously. The occurrence of elastofibroma in other anatomic sites has been reported, although with much less frequency. Elastofibromas display typical diagnostic histologic, cytologic, and electron microscopic features. The use of magnetic resonance imaging can lead to a presumptive diagnosis in elderly individuals with suprascapular lesions. It is important to differentiate this lesion from other soft-tissue lesions, such as sarcomas and desmoid tumors. This study presents a case of bilateral elastofibromas in a 72-year-old man and a review of the literature.     

Bilateral synchronous adrenal myelolipomas: a case report

BACKGROUND: This study was undertaken to assess the outcome of Lichtenstein's tension-free mesh inguinal herniorrhaphy as practised by surgeons in a provincial centre in Taranaki, New Zealand. METHODS: A prospective audit was carried out on all patients who underwent this procedure in Taranaki. They were followed up at 1 month and again at 1 year. Results were entered on a standardized pro forma. RESULTS: One hundred and twenty-four patients underwent 134 repairs by four different surgeons and their registrars. Eighty-two per cent of them had a general anaesthetic, and 13% had local anaesthestic. Twenty-five per cent of the repairs were performed as day surgery and a further 53% required overnight stays. Complication rates were 6% in hospital, 12.7% at I month and 8% at 1 year. Recurrence occurred in one repair (0.9%) and there were no cases of mesh rejection. The wound infection rate was 3% and all were minor. Only 45% of the patients who had an inguinal hemiorrhaphy were employed and they took an average of 16 days (range 2-30) to return to work. Over half felt that that they could have returned to normal activities within 2 weeks. CONCLUSIONS: The Lichtenstein technique of inguinal herniorrhaphy is a technically simple, reliable procedure with minimal morbidity and patients may expect a reasonably prompt return to work and to normal activities.     

Diabetes mellitus-associated glycogen storage hepatomegaly: report of a case and review of the Japanese literature

A huge hepatomegaly was seen in a 30-yr-old female diabetic who was treated with high dose of insulin for her uncontrollable food ingestion. The liver function at the peak of the hepatic enlargement showed a moderate increase of transaminases, alkaline phosphatase, and gamma-glutamyl transpeptidase. The histology of the enlarged liver revealed PAS-positive granules in enlarged hepatocytes, indicating the presence of massive glycogen storage. On admission, she was maintained under a calorie-restricted diet and received approximately 15 to 20 units per day of insulin supplement. At one month after admission, a marked shrinkage of her enlarged liver and restoration of normal liver function were observed concomitantly with the return of fair control of her blood sugar levels. One year later, she had an episode of diabetic ketoacidosis which subsequently was treated with a continuous low-dose infusion of insulin; however, she showed neither hepatomegaly nor liver dysfunction during this episode. There have been 20 cases reported of Japanese diabetics with marked hepatomegaly, in whom the vigorous treatment of diabetic ketoacidosis with insulin seemed to be a trigger of the enlarged liver. This has occurred mostly in patients with insulin-dependent diabetes mellitus. We present a case of non-insulin-dependent diabetes mellitus with glycogen storage hepatomegaly, presumably due to excessive insulin supplements. This suggests that glycogen storage hepatomegaly in diabetics may not be only due to an acute restoration from diabetic ketoacidosis, but may also be due to an overinsulinization in an attempt to maintain a euglycemic condition in spite of excess food intake.     

Hepatocellular carcinoma in primary biliary cirrhosis: a case report and review of the Japanese literature

We present a 66 year-old woman in the cirrhotic stage of primary biliary cirrhosis (PBC), who developed hepatocellular carcinoma (HCC). All serological tests for hepatitis B virus (HBV) and hepatitis C virus (HCV) were negative. We surveyed 16 reported cases (13 females and 3 males) of PBC associated with HCC in Japan. The presence of HCV RNA was determined by the polymerase chain reaction in all of the patients, 3 of whom (19%) were HCV RNA-positive. Although patients with PBC rarely develop HCC, it is suggested that HCV infection may play a minor role in the development of HCC in Japanese patients with PBC.     

Signet-ring cell carcinoma of the ileum: report of a case and review of the Japanese literature

We report herein the extremely unusual case of a 71-year-old woman with signet-ring cell carcinoma of the ileum. She originally presented with a 6-month history of intermittent nausea and abdominal distention, but initial examinations, including gastrointestinal fiberscopy, ultrasonography, and computed tomography (CT) scan, failed to reveal any cause of her symptoms. A barium-enema study performed 11 months after her initial visit demonstrated a narrow portion of the terminal ileum. An ileocecal resection was subsequently performed, and an epigastric subcutaneous tumor was simultaneously excised. The specimen contained a tumor with a stenotic lumen resembling a "lead pipe", an ulcerative portion, and mucosa with a granular appearance adjoining its proximal site. Many small aphthous lesions with IIa + IIc appearance were seen in the apparently normal mucosa. Histopathological examination confirmed a diagnosis of signet-ring cell carcinoma. The small aphthous lesions seemed to be metastases spread via the lymphatic vessels. Our review of the medical literature revealed three cases of signet-ring cell carcinoma of the jejunum; however, this is the first reported case of signet-ring cell carcinoma of the ileum.     

Solitary plasmacytoma of sternum--a case report and review of the Japanese literature

A 39-year-old woman complained of anterior chest pain. A lateral chest X-ray film showed destruction of bone in the body of sternum. CT scan showed a soft tissue density within the sternum. Serum protein electropheresis revealed mild monoclonal gammopathy of IgG-kappa, but the urine contained no Bence-Jones protein. A biopsy specimen showed plasmacytoma with cytoplasmic Ig IgG-kappa. Bone scintigraphy and systemic bone roentgenography revealed only the lesion in the sternum. Sternal subtotal resectin was performed. The defect of the anterior chest wall was reconstructed with double folded marlex mesh and pedicles from the major pectoral muscle. Iliac bone marrow aspiration revealed no evidence of myeloma. There was no serum evidence of monoclonal gammopathy two months after the operation. Therefore, the final diagnosis was solitary plasmacytoma of the sternum. It is now 41 months since surgery, and there have been no signs of fecurrence. Long term follow up is necessary in this case.     

Cryptococcal myositis: a case report and review of the literature

Only rare cases of cryptococcal myositis have been previously reported in the literature. All of these cases have occurred in the setting of human immunodeficiency virus (HIV) infection. We report a case of cryptococcal myositis diagnosed premortem on a needle biopsy in a heart transplant patient undergoing immunosuppressive therapy.     

Riedel's thyroiditis: a case report and review of the literature

Riedel's thyroiditis is a very rare disease of unknown aetiology, occasionally associated with retroperitoneal and mediastinal fibrosis. It is a benign condition, but may be confused with an anaplastic carcinoma of the thyroid. The differential diagnosis with anaplastic carcinoma is assured only by intraoperative biopsy. The Authors report a clinical case: symptoms were a progressive enlargement of the thyroid gland, left recurrential palsy, dyspnoea and dysphagia. The surgical treatment was total thyroidectomy, performed with bilateral neurolysis of recurrent nerves. The patient was also under adjuvant corticosteroid treatment.     

Atelencephalic microcephaly: a case report and review of the literature

Rapid changes in the circulating blood volume or hemoglobin level during apheresis may pose a risk for healthy individuals donating allogeneic PBSC. In this study, a real-time noninvasive monitor CRIT-LINE was used for continuous monitoring of hematocrit values in a total of 16 aphereses performed in 4 adult (median age 30 years) and 4 pediatric donors (4 years). Donors received recombinant G-CSF (10 microg/kg s.c. for 5 days) for mobilization of PBSC. A CS3000 plus blood cell separator (Baxter) was used in two different procedures. Adults donors were subjected to modified program 1-120 using a combination of the granulocyte chamber and the small volume collection chamber (SVCC), and pediatric donors were subjected to specialized program 4 with a combination of the newly developed small volume separation chamber holder (SVSCH) and SVCC. In all of the procedures for children, the extracorporeal line was primed with 400 ml leukocyte-depleted allogeneic RBC or 200 ml autologous RBC after regular priming with normal saline, whereas none of the adult donors received this treatment. We found a marked contrast in the hematocrit kinetics during apheresis in the two cohorts/procedures. In adults, the initiation of apheresis was followed by an immediate decline in the hematocrit value over the initial 10 min until a stable plateau level was reached (7% decrease). In children, the values decreased slowly but progressively throughout the entire procedure to finally reach a 9% decrease at the completion of apheresis. These data may suggest that the use of SVSCH plus SVCC or priming with RBC can eliminate the abrupt decline in blood hemoglobin levels that occurs during apheresis.     

Duodenal phytobezoar: a case report and review of the literature

Phytobezoars are an unusual cause of small bowel obstruction. We report a case of small bowel obstruction due to phytobezoar in a 63 year-old female patient who had undergone gastric surgery (truncal vagotomy with pyloroplasty) for duodenal ulcer disease complicated by gastric outlet obstruction 10 years ago. We diagnosed this bezoar case by radiologic methods and these methods keep their importance for the diagnosis of small bowel obstruction with phytobezoars.     

Gallbladder diverticulum: a case report and review of the literature

BACKGROUND: The clinical significance of the 14 and 6 positive spikes (PS) electroencephalographic (EEG) phenomenon is not well established. This study was performed to provide further data regarding the clinical correlates of the PS, particularly attention-deficit/hyperactivity and somatic symptoms. METHODS: Diagnostic information gathered through structured interviews was compared among four groups of psychiatric inpatients aged 4-17 years who underwent an EEG examination over a 2-year period. Groups consisted of patients with: 1) 14 and 6 PS (n = 25); 2) epileptic discharges (n = 29); 3) slow-wave abnormalities (n = 23); and 4) a normal EEG group age and sex matched to the 14 and 6 PS group (n = 25). RESULTS: Attention-deficit hyperactivity disorder (ADHD) symptoms were significantly more frequent in the PS group (chi 2 = 2.96, p < .05) compared to the other three groups combined. Although somatic symptoms were not increased in the 14 and 6 PS group, anxiety symptoms tended to occur more in this group (chi 2 = 3.50, p < .06). CONCLUSIONS: The PS profile appears associated with ADHD symptoms. Possible treatment implications of this finding (e.g., use of anticonvulsants in ADHD patients with PS) need to be explored.     

Congenital microgastria: a case report and review of literature

Congenital microgastria is an uncommon result of impairment of normal foregut development. To date, only 39 cases have been described in the literature. We report a boy born with microgastria and bilateral hypoplastic kidneys who had feeding problems, resulting in failure to thrive and growth retardation. After a short period of conservative management, he was operated upon at the age of 11 months. A Hunt-Lawrence pouch was created, leading to toleration of increasing amounts of oral feeding. Although his feeding problems have decreased, his height and weight are below normal (<10th percentile). The embryology, clinical presentation, diagnostic procedures, associated anomalies, and management are discussed.     

Gastric leiomyoblastoma: literature review and report of a case

The extended V-Y flap, a modified V-Y advancement flap, is very useful in closing relatively large defects on the face. Its extension limb is hinged down as a transposition flap on the end of the V-Y advancement flap to close the most distal portion of the defect. We applied this flap in closing a defect following excision of skin tumors on the face with excellent cosmetic results in 11 patients. However, this flap tended to make a distortion at the base of the flap in the primary closure site. By drawing figures, we concluded that the distortion was due to the characteristic of this technique as a V-Y advancement-rotation flap or V-Y advancement flap with rotation.     

Phenacetin-induced sulfhemoglobinemia: report of a case and review of the literature

Phenacetin-induced sulfhemoglobinemia was diagnosed in a middle-aged woman with a 6-month history of cyanosis and a 10-year history of ingestion of analgesics. The laboratory and clincial diagnosis of sulfhemoglobinemia and methemoglobinemia are discussed. The reviewed medical literature suggests that the cyanosis of chronic phenacetin or acetanilid use is generally due to sulfhemoglobinemia rather than methemoglobinemia.     

Odontogenic keratocysts: review of the literature and report of a case

The beta 3-adrenergic receptor (beta 3AR) is expressed in visceral fat and is a regulator of resting metabolic rate, thermogenesis, and lipolysis. We genotyped 61 unrelated Mexican Americans for a variant in the beta 3AR gene (codon 64 TGGTrp-->CGGArg; TRP64ARG). The allele frequency was 0.13. The TRP64ARG variant was significantly associated with an earlier age of onset of non-insulin-dependent diabetes mellitus (41.3 +/- 4.6 years vs 55.6 +/- 2.6 years; P < 0.02) and in non-diabetics, with elevated 2-h insulin levels during an oral glucose tolerance test (810 +/- 120 pmol/l vs 384 +/- 6 pmol/l; P < 0.005). Non-diabetic subjects with the variant allele tended to have higher body mass indices (BMI), waist-to-hip ratios, and diastolic blood pressures. The study group was expanded to include 421 related subjects from 31 families in the San Antonio Family Diabetes Study. Using a measured genotype analysis approach to estimate genotype-specific means for each trait, those who were homozygous for the TRP64ARG variant had significantly higher 2-h insulin levels (P = 0.036) and trends towards higher BMI compared to the other two genotypes. We detected no associations of these traits in the TRP64ARG heterozygotes in the larger group. We conclude that the TRP64ARG beta 3AR variant is a susceptibility gene for several features of the insulin resistance syndrome in Mexican Americans. Since its effects are modest, study design (e.g., subject selection, genetic background, and statistical analyses) may influence which traits are associated with this variant and whether or not the effect is detectable in heterozygotes.     

Chylothorax: case report and review of literature

C57BL/6J-Min/+ mice, which are heterozygous for a non-sense mutation in the Apc gene, provide a model for both familial adenomatous polyposis and sporadic colon cancers. In our study, gut tumors and small intestine lymphoid nodules were counted in Min mice fed fiber-enriched diets for 6 weeks. Neither starch-free wheat bran nor resistant starch modified the number of tumors. However, short-chain fructo-oligosaccharides dramatically reduced the incidence of colon tumors and concomitantly developed gut-associated lymphoid tissue. Our experiment shows that short-chain fructo-oligosaccharides counteract advanced stages of colon carcinogenesis, possibly via stimulation of antitumoral immunity by modulation of the colonic ecosystem.
