Hyperparathyroidism in pregnancy: case report and review of the literature.

The apparent incidence of hyperparathyroidism (HPT) is low in pregnancy but will likely increase now that more asymptomatic HPT is being diagnosed. However, since the serum calcium levels are decreased in pregnant women, mild primary HPT may go unrecognized. In untreated cases of HPT, complications during pregnancy or during the neonatal period have included spontaneous abortion, stillbirth, neonatal death, neonatal tetany and hypercalcemia. A review of the literature indicates a substantial improvement in fetal outcome when parathyroidectomy is done during pregnancy, as in the case reported here. Therefore, parathyroidectomy is the treatment of choice when the diagnosis is made during pregnancy, although oral phosphate therapy may be an alternative if surgery is contraindicated.     

Human pentastomiasis in China: case report and literature review

A 13-yr-old boy was admitted because of persistent fever, abdominal pain and diarrhea for 3 mo. Abdomen CT revealed hepatomegaly and multiple nodular low-density pathological changes. At laparotomy considerable yellow and turbid ascites were seen in the abdominal cavity and miliary nodules were noted on the surface of the omentum majus, liver, and small intestine wall. Histological examination revealed parenchymal tubercles containing several worms. Pathological diagnosis was parasitic granuloma. These parasites were identified as Porocephalus taiwana sp.nov. The patient made an uneventful recovery after therapy and was discharged. Moreover, another 17 cases of human pentastomiasis reported from China were reviewed. Human pentastomiasis is an extremely rare disease and this is only the second case of human Porocephalus taiwana sp.nov infection. Pentastomiasis should be considered in differential diagnosis of patients with a history of abdominal symptoms and eating of poorly-cooked snakes.     

Cutaneous ciliated cyst: case report and literature review

An 18-year-old girl had a cyst excised from the left buttock in 1988. The cyst was diagnosed to be a cutaneous ciliated cyst, since histologic examination using special stains demonstrated its lining to be similar to fallopian tube epithelium. Only 20 such cases have been published to date, and this report is probably the first case in the plastic surgical literature, to the best of our knowledge.     

Rhinosporidiosis in Egypt: A case report and review of literature

Rhinosporidiosis is an infection caused by Rhinosporidium seeberi that frequently presents as a polypoidal nasal lesions. Here, we report the first indigenous case of tumoral rhinosporidiosis in Egypt. In this case, a 25-year-old male patient from a rural background of Assuit City presented with epistaxis and a nasal polyp. The patient had not traveled abroad. The diagnosis was established on the morphological basis by the identification of 5- to 10-m endospores and 50- to 1000-m sporangia. The clinicopathological and immunologic features were discussed and the literature was reviewed. To the best of our knowledge this is the first case of this disease to be reported in Egypt in the human literature.

Ganglions of the temporomandibular joint: case report and review of literature

We present the third reported case of a ganglion cyst arising from the temporomandibular joint. Like the previous two cases, this lesion occurred in a woman over the age of 40. Unlike the lesions in previous reports, the cyst in our patient was not associated with pain or tenderness, making the diagnosis of parotid tumor more likely. Nevertheless, the case serves to illustrate the need for including ganglion in the differential diagnosis of well-encapsulated preauricular masses in the region of the temporomandibular joint.     

Lymphoplasmacytic sclerosing pancreato-cholangitis: a case report and review of the literature

Autoimmune pancreatitis is a rare but important cause of pancreatitis that is becoming increasingly recognized in the West. Lymphoplasmacytic sclerosing pancreatitis (LPSP) is a benign form of chronic pancreatitis characterized clinically by infrequent attacks of abdominal pain, jaundice, and weight loss, and pathologically by focal or diffuse chronic or lymphoplasmacytic inflammatory infiltrates centered around pancreatic ducts and ductules, accompanied by obliterative phlebitis, acinar atrophy, and interstitial fibrosis. It has been described alone or as a part of the spectrum of autoimmune gallbladder and biliary tract disease, with clinical, radiological, and pathological overlap reported with primary sclerosing cholangitis. It has been described as "primary sclerosing pancreatitis," "sclerosing cholangitis," "non-alcoholic duct destructive chronic pancreatitis," and "autoimmune pancreatitis." We report a case of LPSP that mimicked pancreatic adenocarcinoma and was subsequently treated with a pylorus-preserving Whipple procedure. This may point towards a primary biliary autoimmune process involving the pancreatic duct, causing a benign form of chronic pancreatitis that may be difficult to characterize pre-operatively to avoid surgery. This case typifies the growing awareness of this relatively recently characterized clinical entity, its similar presentation to pancreatic carcinoma, and the importance for LPSP to be included in the differential diagnosis of pancreaticobiliary disease. Finally, we review the literature.

Carcinoid tumor of the kidney: case report and review of the literature

Carcinoid tumors are low-grade malignant tumors that arise from neuroendocrine cells. Primary renal carcinoid tumors are extremely uncommon. They seem to be more indolent than renal cell carcinomas, although metastases to regional lymph nodes, liver, and bone have been described. The presence of metastases seems to indicate a more malignant course; however, even with metastases a patient might live for 3 or 4 years. Renal carcinoid tumors should be managed by radical or partial nephrectomy, and good outcomes have been obtained for organ-confined disease after radical excision. Conventional methods of imaging are inadequate for detecting smaller carcinoids, so somatostatin receptor scintigraphy should complement computed tomography and magnetic resonance imaging when searching for occult or metastatic disease. Close follow-up after surgery is necessary.     

Mediastinal pancreatic pseudocyst--a case report and review of the literature

Pancreatic pseudocyst, a common complication of acute or chronic pancreatitis, in rare instances may also extend to the mediastinum. A case of 67-year-old woman presenting with a triad of chest pain, dysphagia, and dyspnea is presented. The patient had an episode of acute alcoholic pancreatitis 1 year before presentation. Chest radiography on admission showed a retrocardiac opacity. Two-dimensional echocardiography revealed an echolucent mass compressing the left atrium. A subsequent upper gastrointestinal series for her dysphagia showed extrinsic compression of the distal esophagus. Finally a definitive diagnosis was made with computed tomography (scan), which revealed a 19 x 12 cm pseudocyst extending from the body of pancreas into the thorax and compressing the esophagus and the cardiac chambers. A mediastinal pseudocyst can cause symptoms due to compression or invasion of surrounding structures. The fluid collection may enlarge slowly and hence the symptoms can be delayed as in our patient. The pseudocyst was successfully treated using endoscopic ultrasound-guided transesophageal drainage. Approximately 50 cases of mediastinal extension of the pancreatic pseudocyst in the world literature are reported. At this time, this is only the second time that successful drainage of a mediastinal pseudocyst using a transesophageal approach under endoscopic ultrasound guidance has been reported. The literature was reviewed for clinical presentation, complications, and available treatment options for mediastinal pancreatic pseudocysts.

Limb-shaking transient ischemic attacks: case report and review of literature

Background  

Limb shaking Transient Ischemic Attack is a rare manifestation of carotid-occlusive disease. The symptoms usually point towards a seizure like activity and misdiagnosed as focal seizures. On careful history the rhythmic seizure like activity reveals no Jacksonian march mainly precipitated by maneuvers which lead to carotid compression. We here present a case of an elderly gentleman who was initially worked up as suffering from epileptic discharge and then later on found to have carotid occlusion.     

Limb-shaking transient ischemic attacks: case report and review of literature

Background

Parkinson's disease (PD) is the most common neurodegenerative movement disorder, characterized clinically by resting tremor, bradykinesia, postural instability and rigidity. The prevalence of PD is approximately 2% of the population over 65 years of age and 1.7 million PD patients (age ≥ 55 years) live in China. Recently, a common LRRK2 variant Gly2385Arg was reported in ethnic Chinese PD population in Taiwan. We analyzed the frequency of this variant in our independent PD case-control population of Han Chinese from Taiwan.

Methods

305 patients and 176 genetically unrelated healthy controls were examined by neurologists and the diagnosis of PD was based on the published criteria. The region of interest was amplified with standard polymerase chain reaction (PCR). PCR fragments then were directly sequenced in both forward and reverse directions. Differences in genotype frequencies between groups were assessed by the X ² test, while X ² analysis was used to test for the Hardy-Weinberg equilibrium.

Results

Of the 305 patients screened we identified 27 (9%) with heterozygous G2385R variant. This mutation was only found in 1 (0.5%) in our healthy control samples (odds ratio = 16.99, 95% CI: 2.29 to 126.21, p = 0.0002). Sequencing of the entire open reading frame of LRRK2 in G2385R carriers revealed no other variants.

Conclusion

These data suggest that the G2385R variant contributes significantly to the etiology of PD in ethnic Han Chinese individuals. With consideration of the enormous and expanding aging Chinese population in mainland China and in Taiwan, this variant is probably the most common known genetic factor for PD worldwide.     

Nasopharyngeal mucoepidermoid carcinoma: A case report and review of literature

Background

Salivary gland-type tumors originating in the nasopharynx are rare, and only a few articles about mucoepidermoid carcinomas (MEC) in this location have been reported. We describe one case of nasopharyngeal MEC and, based on a review of the literature, discuss different therapeutic approaches that can be taken regarding the result of histological findings, radiological tests and extent of disease.

Case presentation

A 47-year-old woman diagnosed with mucoepidermoid carcinoma of nasopharynx, T1 N3 M0 (stage IV-B) was treated in 2007 with a combination of radiotherapy and chemotherapy to a maximum dose of 70 Gy and concomitant Cisplatin during the radiation. One year later, with the head and neck disease under control, mediastinal nodes relapse appeared which were treated with exclusive radiotherapy to a maximum dose of 65 Gy. One year after the first relapse, a second relapse was detected in the right lung, next to the previously treated mediastinal regions, and the patient initiated a treatment with exclusive chemotherapy based on TPF scheme.

Conclusion

For limited or resectable MEC, combined surgery with radiotherapy, or radiochemotherapy, should be considered the main treatment policy. On the other hand, in poorly differentiated, unresectable tumors or nasopharyngeal MEC, radiochemotherapy could be currently the main treatment approach.     

Malignant struma ovarii: report of a case and review of the literature

Malignant struma ovarii is a very rare disease and therefore there is neither common agreement on treatment regimens nor sufficient follow-up experience. The case of a 38-year-old woman with malignant struma ovarii is described. The patient presented with a clinically silent ovarian neoplasm discovered incidentally during investigations for metrorrhagia. The ovarian mass was resected and the tumor was found to be a teratoma. Within the teratoma a papillary thyroid carcinoma of the follicular variant was found. Subsequently, in order to make follow-up of the patient possible by thyroglobulin measurement and radioiodine whole body scintigraphy, near-total thyroidectomy was performed and the thyroid was found to be normal on histology. Whole body radioiodine scintigraphy with (131)I and ablation of the thyroid remnant by the administration of 80 mCi (131)I was performed. The patient recovered uneventfully and is now well.
