Purpose: The purpose of this report is to present a case of persistent parotid fistula treated successfully with preoperative botulinum toxin type A injection into the parotid parenchyma, followed by fistulectomy. Methods: A 72-year-old female patient presented to the hospital with a 5-month history of clear, watery discharge from a tiny opening on the left cheek, which increased during food intake. A chemistry test of the fluid revealed an high amylase level. An ultrasonography of left parotid gland showed a $1.13{\times}0.6cm$ sized fistula. After demarcating the left parotid gland with assistance of ultrasonography, a total 40 units of botulinum toxin type A (Botox, Allergan, Irvine, CA) was injected into 4 subdivisions of the left parotid gland. The clear serous discharge ceased completely on the 5th day after botulinum toxin injection. On the 7th day, a fistulectomy was performed under the local anesthesia. Results: The parotid fistula healed completely without complications. During the 6-month follow up period, there was no discharge from the cheek. Conclusion: On the basis of our experience with type A botulinum toxin as a local anticholinergic agent in treating parotid fistula, preoperative botulinum toxin A injection seems to be very useful to prevent recurrence after fistulectomy.
Three dogs (a 30-month-old spayed female English bulldog; a 12-month-old castrated male English bulldog; a 19-month-old castrated male Shar-pei dog) were presented to the Dana Animal Hospital Eye Center with clinical signs of blepharospasm, epiphora, and ocular discharge (serous to mucopurulent) in one or both eyes. Through ophthalmic examination, the dogs (5 eyes) were diagnosed with trichiasis caused by upper and lower eyelid entropion, including the lateral canthus. To correct upper and lower eyelid entropion, modification using a combination of the Stades forced granulation method for upper eyelid entropion and Hotz-Celsus procedure for lower eyelid entropion was performed in all cases. At the last follow-up, mean 274 days after surgery, clinical signs disappeared and no recurrences of entropion were observed in any of the 3 dogs (5 eyes). Therefore, the combination of the Stades forced granulation method and Hotz-Celsus procedure may be an effective treatment for trichiasis caused by upper and lower eyelid entropion in dogs.
Seahorses, which have been cultivated since the 2000s, are economically very important. Gas bubble disease (GBD) is a significant concern in the cultivation of seahorses; therefore, this study aimed to determine the cause of GBD-induced death in two species of Syngnathidae (Syngnathus schlegeli and Hippocampus haema). Rod-shaped bacteria were observed histopathologically and identified as Vibrio splendidus by conventional and real-time PCR analyses. The lethality of V. splendidus varies depending on the host's immune status, and the disease can be prevented through water quality management or improvement of the breeding environment. In this study, the GBD lesions (gas bubbles) were observed at 12℃, 8.0 mg/L of dissolved oxygen, 30 ppt of salinity, and pH 7.7. In addition, rod-shaped bacteria, infiltration of inflammatory cells, and extensive serous exudate were confirmed in the lesions where gas bubbles were found. PCR analysis was able to detect V. splendidus, possibly a secondary infection of the immunocompromised syngnathid fish. Understanding the risk of immunity control and the correlation between these lesions and causal agents will be of great help to the aquaculture industry and the ornamental fish market.
Primary peritoneal psammocarcinoma is a rare type of serous carcinoma that is characterized by the massive formation of psammoma bodies and the invasion of adjacent organs. A 55-year-old female who previously underwent a hysterectomy presented to the emergency room with severe abdominal pain. Contrast-enhanced CT revealed an intra-abdominal calcific mass. Initially, it was thought to be a heterotopic ossification due to the previous pelvic surgery with intact ovaries. However, this was diagnosed as a primary peritoneal psammocarcinoma. Primary peritoneal psammocarcinoma is a very rare disease entity that should be considered a differential diagnosis in patients with normal ovaries, massive ossification in the pelvic cavity, and calcific peritoneal nodules.
Purpose : Xerostomia is a complication met by almost all patients who have radiotherapy for cancers of head and neck. Many studies for prevention of xerostomia will be necessary. Radiation-induced acute response of salivary glands has been defined as interphase death or apoptosis. Increased intracellular calcium level have an important role in radiation-induced apoptosis. Calcium channel blocker may prevent radiation-induced apoptosis of salivary glands. This study was designed to evaluate the effectiveness of diltiazem known as calcium channel blocker and pentoxifylline with inhibition of inflammatory response on the apoptosis as an acute response of radiation in rat salivary glands. Materials and Methods : Sprague-Dawley rats with about body weight 200-250 g were divided into 5 study groups : control, radiation alone, diltiazem with radiation, pentoxifylline with radiation, and diltiazem and pentoxifylline with radiation. The diltiazen and pentoxifylline were injected intraperitoneally 20 mg/kg and 50 mg/kg, 30 and 20 mimute before irradiation. respectively. Irradiation was given with a 4 MV linear accelerator. The 1600 cGy of radiation was delivered in a single fraction through a single anterior portal encompassing the entire neck. After 24 h of irradiation, rats were sacrificed and parotid and submandibular glands were removed and stained with hematoxylin and eosin. The quantification of apoptosis was performed by microscopic examination of stained tissue sections at a magnification of 200X and the percentage of apoptotic cell was calculated. Results : On parotid glands, the percentage of apoptosis by radiation alone, diltiazem with radiation, pentoxifylline with radiation, and diltiazem and pentoxifylline with radiation were 1.72$\%$ (8.35/486), 0.64$\%$ (2.9/453), 0.23$\%$ (1.2/516), and 0.28$\%$ (1.1/399), respectively. The apoptosis was markedly reduced in the groups receiving drugs compared with groups receivinge, radiation alone (p<0.05). In serous cell of submandibular glands, the percentages of apoptosis of radiation alone, diltiazem with radiation, pentoxifylline with radiation, and diltiazem and pentoxifylline with radiation were 1.94$\%$ (l1/567), 0.34$\%$ (1.9/554), 0.28$\%$ (1.8/637), and 0.22$\%$ (1.3/601), respectively. In the mucus cell of submandibular glands, the percentages of apoptosis were 0.92$\%$ (5.1/552), 0.41$\%$ (2.5/612), 0.29$\%$ (1.3/455), and 0.18$\%$ (1.0/562), respectively. The apoptosis was markedly reduced in the serous glands (p<0.05), but there was no difference in development of apoptosis in each group of mucus gland. Conclusion : These results suggest that radiation-induced apoptosis of serous cells of salivary glands may be decreased by diltiazem and pentoxifylline administration.

Background: Epithelial ovarian cancer (EOC) is the commonest malignancy involving the ovaries. Maximum surgical cytoreduction (MCR) followed by adjuvant taxane-platinum chemotherapy are the standard of care treatments. Aims: To study treatment outcomes of EOC patients that were maximally cyto-reduced and received adjuvant paclitaxel-carboplatin (PC) chemotherapy. Materials and Methods: This retrospective cohort study included 174 patients with EOC treated at the Egyptian National Cancer Institute between 2006 and 2010. For inclusion, they should have had undergone MCR with no-gross residual followed by adjuvant PC chemotherapy. MCR was total abdominal hysterectomy/bilateral salpingo-oophorectomy [TAH/BSO] or unilateral salpingo-oophorectomy [USO] plus comprehensive staging. Results: The median age was 50 years. Most patients were married (97.1%), had offspring (92.5%), were postmenopausal (53.4%), presented with abdominal/pelvic pain and swelling (93.7%), had tumors involving both ovaries (45.4%) without extra-ovarian extension i.e. stage I (55.2%) of serous histology (79.9%) and grade II (87.4%). TAH/BSO was performed in 97.7% of cases. A total of 1,014 PC chemotherapy cycles were administered and were generally tolerable with 93.7% completing 6 cycles. Alopecia and numbness were the commonest adverse events. The median follow up period was 42 months. The 2-year rates for disease free survival (DFS) and overall survival (OS) were 70.7% and 94.8%, respectively. The respective 5-year rates were 52.6% and 81.3%. Advanced stage and high-grade were significantly associated with poor DFS and OS (p<0.001). Age >65 years was associated with poor OS (p =0.008). Using Cox-regression, stage was independent predictor of poor DFS and OS. Age was an independent predictor of poor OS.

Objectives: This review aims to report the efficacy and safety of electroacupuncture in the treatment of primary dysmenorrhea. Methods: We searched for randomized controlled studies (RCTs) using electroacupuncture on primary dysmenorrhea up to Dec 2016. The following databases were searched : OASIS, PubMED, EMBASE, CENTRAL. The results of the studies were analyzed and the risk of bias was assessed. Results: Five studies were included in this review. In most studies, the effect of electroacupuncture at Sameumgyo (SP6) was better than that of electroacupuncture at Hyeonjong (GB39), nonacupoint and no intervention about Visual analog scale (VAS), Verbal rating scale (VRS) and Retrospective symptom scale (RSS). But there were no significant effects on Resistance Index (RI) and S/D ratio (the ratio between peak systolic to end-diastolic flow velocity in uterine arteries). Serous adverse events were not reported. Conclusions: This review shows that electroacupuncture is effective on primary dysmenorrhea with no serious adverse events.
Acinic cell carcinoma is a slow-growing solid neoplasm of salivary gland. Although their cytological and histological finding is bland-looking, their biological behavior is unpredictable. We experienced two cases of acinic cell carcinoma of the salivary gland diagnosed by fine needle aspiration biopsy and confirmed by tissue examination. They showed different clinical courses. We compared their cytologic and histologic findings. The first case was a right preauricular mass in a 58 year-old female of 3 years duration. The cytologic smear revealed sheets or small clusters of monotonous cells mimicking normal serous acinar cells with little cellular pleomorphism. She underwent superficial parotid lobectomy. The tumor was a well demarcated 1.5cm sized nodular mass without infiltration into surrounding parenchyme. The second case was a left submandibular mass in a 23 year-old male of 4 years duration. The smear showed more severe pleomorphism of the tumor cells than those of previous case. Excisional biopsy was done. The excised tumor was $5.5{\times}3.5{\times}3cm$ sized multilobulated solid mass with invasion into surrounding parenchyme. The tumor recurred after 20months, thus total excision of the mass and modified radical neck dissection was carried out. From the above findings, cytologic atypism, infiltrative growth pattern and type of initial therapy may be correlated with biologic behavior.
Immunohistochemical studies on S-100 protein and lactoferrin were carried out to evaluate the existence and distribution pattern of S-100 protein and lactoferrin positive cells in salivary gland tumors. The specimens used were 25 cases of pleomorphic adenoma, 2 cases of monomorphic adenoma, 2 cases of mucoepidermoid tumor, 2 cases of acinic cell tumor, 3 cases of adenoid cystic carcinoma and 2 cases of adenocarcinoma occured in parotid and submandibular salivary gland. ABC kits(Dako corp. Copenhagen. Denmark) for S-100 protein and lactoferrin were used. The results obtained were summarized as follows: In the normal salivary gland. positive immunoreaction for S-100 protein was observed in myoepithelial cells of acini and intercalated ducts. Positive immunoreaction for lactoferrin was observed in serous acinic cells, epithelial cells of intercalated ducts, and excretory material in the ductal lumina. In the pleomorphic and monomorphic adenomas. most of tumor cells were positive for S-100 protein, while luminal tumor cells in gland-like or duct-like structures were rarely positive for lactoferrin. In mucoepidermoid tumor, most of squamous cells and a few of intermediate cells were positive for S-100 protein, but all of tumor cells were negative for lactoferrin. In acinic cell tumor, most of tumor cells were positive for lactoferrin, but all of tumor cells were negative for S-100 protein. In adenoid cystic carcinoma, basaloid tumor cells in trabecular structure were focally positive for S-100 protein. and in adenocarcinoma, many of tumor cells were posivive for both S-100 protein and lactoferrin. Thus, according to the embryonic stage of the development of the tumor cell origin, it was possible to classify the salivary gland tumor as followings: mucoepidermoid carcinoma which originated from the earliest stage, acinic cell tumor which originated from the end stage. Between these two extremes, there were pleomorphic adenoma, adenoid cystic carcinoma and adenocarcinoma which originated in the middle stage of the development of .the salivary glands. Based on the above results, it can be stated that S-100 protein is demonstrated in tumor cells orginated from myoepithelial cells and lactoferrin in glandular differentiated tumor cells.
Purpose: We performed vastus lateralis (VL) muslce or myocutaneous flap for close of the trochanteric skin defect usually happened in paraplegia and report our 6 cases. Materials and Methods: Between March 2004 and August 2005 we performed 4 cases of VL muscule flap with skin graft and 2 cases of VL myocutaneous flap for close of the trochanteric skin defect in 6 paraplegia patients. There were 5 men and 1 woman and mean age was 52.2 years and mean diameters of skin defect was $8.3{\times}8.3\;cm$. The mean follow up period was 18 months. The survival of flap, complications, healing time and patient's satisfaction were evaluated. Results: All flaps were survived except 1 case of margin necrosis. In 2 cases, blood-serous discharges were continued after operation which might be due to dead space and treated with $2{\sim}3$ times debridement and delayed close. Mean time to heal the skin defect was 7.6 weeks. No infection and recurrence in follow up periods. Cosmetic results judged by patients are that 3 cases are good and 3 cases are fair. Conclusion: VL muscle and myocutaneous flap is good treatment method among the numerous methods in treatment-failed cases of trochanteric skin defects of paraplegia patients. This surgical procedure is simple, constant blood supply, good pliability, cosmetic results and also appliable to other skin defect of pelvis girdle like sacrum and ischium.
