Ovarian torsion in puerperium: A case report and review of the literature

INTRODUCTION

Ovarian torsion (OT) is a rare cause of acute abdominal pain that requires prompt recognition and treatment during puerperium. Diagnosis of OT can be challenging due to nonspecific clinical features and uncommon objective findings. The management of OT is often delayed because of diagnostic uncertainty. Early and timely recognition and prompt intervention are crucial to preserve ovarian function and to minimize morbidity.

PRESENTATION OF CASE

We report a 29-year-old postpartum woman who presented to the emergency department (ED) with severe right flank pain, nausea and anorexia initially considered as renal colic. After further investigation, OT caused by large mucinous cyst was diagnosed. Right-sided salpingo-oophorectomy was performed due to hemorrhagic ovary and huge cystic mass causing ischemic OT.

DISCUSSION

OT is often diagnosed based on the clinical presentation, including severe, sharp, sudden onset of unilateral lower abdominal pain and tenderness with a palpable laterouterine pelvic mass and nausea/vomiting. Emergency surgical intervention should be performed if OT is suspected to confirm the diagnosis and uncoil the twist to prevent ovarian damage.

CONCLUSION

In conclusion, emergency physicians should be aware of the possibility of OT in postpartum women. Therefore, early and timely surgical intervention should be undertaken.     

Recommendations for Hepatitis B Immunoglobulin and Antiviral Prophylaxis Against Hepatitis B Recurrence After Liver Transplantation

The combination of hepatitis B immunoglobulin and potent nucleos(t)ide analogs after liver transplantation is considered as the standard of care for prophylaxis against hepatitis B virus recurrence. However, the recommended doses, route of administration, and duration of HBIG administration remain unclear. Moreover, hepatitis B immunoglobulin-free prophylaxis with potent nucleos(t)ide analogs has shown promising disease outcomes in preventing hepatitis B virus recurrence. The current recommendations, produced by the Turkish Association for the Study of the Liver, Acute Liver Failure and Liver Transplantation Special Interest Group, suggest a reduced need for hepatitis B immunoglobulin administration with effective long-term suppression of hepatitis B virus replication using potent nucleos(t)ide analogs after liver transplantation.     

Thyroid disorders in hemodialysis patients in an iodine-deficient community

There are various changes in the thyroid gland and its function in chronic renal failure (CRF). These changes include lower levels of circulating thyroid hormone, altered peripheral hormone metabolism, decreased binding to carrier proteins, possible reduction in tissue hormone content, and increased iodine storage in the thyroid gland. The decrease of excretion of urinary iodine in CRF increases serum inorganic iodine level and iodine content of the thyroid, which consequently enlarges the gland. This study is designed to investigate the prevalence of goiter and thyroid dysfunction in patients with end-stage renal disease (ESRD) on hemodialysis (HD) in an iodine-deficient community. Eighty-seven (40 females and 47 males) HD patients and 169 (79 females and 90 males) healthy individuals as controls are included. Sex ratios for the patient and control groups are 0.85 and 0.88, respectively. Mean ages for the patient and control groups are 42.94 +/- 11.88 and 40.20 +/- 10.72 years, respectively. Examination of the thyroid gland using ultrasonography along with simultaneous measurement of blood levels of free-T4 (FT4), free-T3 (FT3), and thyrotropin (TSH) are made for every individual. The presence of goiter demonstrable by ultrasonography is found in 32.2% of the uremic patients and in 23.5% of the controls and its prevalence increases with age (P = 0.01). In 32 (36.8%) of the patients and 29 (17.1%) of the controls at least one thyroid nodule is found in ultrasonography. Between patients with or without a nodular goiter the authors could not observe any difference for duration of dialysis and serum levels of TSH, FT4, FT3, calcium, and albumin. In ESRD patients the prevalence of nodular goiter is higher for females (47.5% vs. 27.7%, P = 0.045) and increases with age (P = 0.04). Though incidence of hyperthyroidism is found to be similar for the two groups (1.14% in ESRD patients vs. 1.10% in controls), hypothyroidism is observed in 3.4% of ESRD patients but only 0.6% of controls. This high incidence of hypothyroidism and nodular goiter in ESRD patients shows that screening for thyroid dysfunction and goiter, using appropriate laboratory tests and ultrasonography, should be considered in evaluation of every ESRD patient.     

Sialoblastoma of the parotid gland

A 3 year-old girl presented with a 6- months history of facial swelling in the region of cheek. Physical examination revealed a firm, non-tender, non- erythematous, mobile, 3 × 3 cm mass in the right cheek. Fine needle aspiration biopsy of the mass demonstrated significiant mitotic activity, slight pleomorfism and atypical cells. A transoral incisional biopsy was also done for accurate diagnosis and the tumor was diagnosed as sialoblastoma. After performing superficial parotidectomy, the tumor was excised with large margins. No adjuvant treatment was given and no recurrence has been noted after 6 months. Despite the rareness of the disease, pathologists and otolaryngologists should always consider the possibility of sialoblastoma of salivary glands in childhood and it can be best described as locally agressive with malignant potential.     

Curcumin ameliorates impaired insulin/IGF signalling and memory deficit in a streptozotocin-treated rat model

Increased serum insulin levels and reduced peripheral insulin activities seen in insulin resistance syndrome are associated with age-dependent cognitive impairment and Sporadic Alzheimer’s Disease (SAD), suggesting a disturbance in the insulin signalling system in the brain and possibly being one of the causes of dementia. Therefore, the streptozotocin (STZ)-induced animal may be an appropriate model for the investigation of SAD and related dementia. This study was designed to investigate the beneficial effect of Curcumin (CUR), a neuroprotective agent, on intracerebroventricular (ICV) STZ-induced cognitive impairment in rats. For this purpose, adult male Wistar rats were bilaterally ICV injected with STZ (3 mg/kg). An artificial cerebrospinal fluid (aCSF) was given to the control group (SHAM) instead of STZ on days 1 and 3. Learning and memory performance were assessed using the “passive avoidance task” and the “Morris water maze test”. After confirmation of acquisition impairment with these tests, the STZ group was divided into two subgroups: STZ + vehicle (Vh) and STZ + CUR. The rats in the SHAM and STZ + Vh groups were administered intraperitoneally with 0.5 ml Vh and the rats in the STZ + CUR group were treated intraperitoneally with CUR (300 mg kg⁻¹ day⁻¹ in Vh) for 10 days starting from the 25th day after STZ injection. The Morris water maze test was reapplied on the 35th day after STZ injection and all of the rats were sacrificed on day 36 for quantitation of IGF-1 and for histopathological evaluation. Rats in the STZ + CUR group were found to have a higher performance in cognitive tests than rats in the STZ + Vh group (P < 0.01). In parallel with the cognitive tests, IGF-1 levels were decreased in all of the STZ-injected groups (1.78 ± 0.34) compared to the SHAM group (3.46 ± 0.41). In contrast, CUR treatment significantly increased IGF-1 levels (P < 0.001). The degree of neuronal loss decreased after CUR treatment compared to the SHAM group (P < 0.02). These results clearly indicate that CUR treatment is effective in reducing the cognitive impairment caused by STZ in rats, and may be a potential therapeutic agent for altering neurodegeneration in SAD.     

A coincidence of renal cell carcinoma and hematological malignancies

Hematological malignancies with renal cell carcinoma (RCC) are rarely seen. We reported here two cases of coincidence of RCC with multiple myeloma (MM) and Hodgkin??s disease (HD). A 69-year-old male patient with tumor that was located at the upper pole of left kidney was admitted to our clinic. Partial tumoral resection was perfomed and stage-I RCC was diagnosed after the histopathological examination of tumor. Moreover, he was diagnosed with IgG kappa stage-IIA MM as a result of bone marrow examination and serum immunofixation electrophoresis. Radiotherapy, combination chemotherapy, and autologous stem cell transplantation (ASCT) were performed. The patient is still alive who achieve a complete remission. A 53-year-old male patient suffered from cervival lymphadenopathy. He has a story of right radical nefrectomy that has been performed 4?years ago. Stage II-B lymphocyte-predominant HD was diagnosed. Combination chemotherapy was started, but relapse occurred 25?months later. ASCT was not planned due to cardiovascular problems and the patient died. Clinicans should keep in mind the coincidence of RCC with MM and HD.     

Scleral buckling technique for longstanding inferior rhegmatogenous retinal detachments with subretinal bands.

We investigated the effectiveness and safety of conventional surgery on longstanding retinal detachments (RD) with subretinal bands (SRB). We found that conventional surgery were safe and effective method in the treatment of inferior chronic rhegmatogenous RD cases with SRB without other signs of advanced proliferative vitreopathy. Further studies with larger numbers and longer follow up are needed.
