While a sprain of the hamstring muscle is relatively common in athletes or those who participate in physically active sports, a complete rupture of the proximal hamstring is relatively rare. A rupture of the long head of the biceps femoris without rupture of the semimembranosus and semitendinosus muscles has rarely been reported. In this study, we saw relatively favorable outcomes after reattachment with a suture anchor at the ischial tuberosity in two patients who had a rupture of the long head of the biceps femoris.

BACKGROUND: Meniscus tears are commonly associated with anterior cruciate ligament (ACL) ruptures. It is essential to repair meniscal tears as much as possible to prevent early osteoarthritis and to gain additional stability in the knee joint. We evaluated the results of arthroscopic all-inside repair using the Meniscal Viper Repair System (Arthrex) on meniscus tears simultaneously with ACL reconstruction. METHODS: Nineteen out of 22 patients who were treated with arthroscopic all-inside repair using the Meniscal Viper Repair System for meniscus tear associated with ACL rupture were evaluated. ACL reconstructions were performed at the same period. The mean follow-up period was 16.5 months (range, 12 to 24 months). The clinical results of the meniscus repair were evaluated by symptoms (such as catching or locking), tenderness, effusion, range of motion limitation, and the McMurray test. Clinical success was defined by negative results in all five categories. The Hospital for Special Surgery (HSS) score was evaluated. Objective results were evaluated with secondary look arthroscopy or magnetic resonance imaging (MRI). The MRI results were categorized as completely repaired, incompletely repaired, and failure by Henning's classification. The results of second-look arthroscopy were evaluated with the criteria of meniscal healing. RESULTS: The clinical success rate was 95.4% and the HSS scores were 93.9 +/- 5.4 at the final follow-up. According to Henning's classification, 15 out of 18 cases showed complete healing (83.3%) and two cases (11.1%) showed incomplete healing. Seventeen out of 18 cases that underwent second-look arthroscopy showed complete healing (94.4%) according to the criteria of meniscal healing. Only one case showed failure and the failure was due to a re-rupture at the sutured area. Complications of ACL reconstruction or meniscus repair were not present. CONCLUSIONS: The results demonstrate that arthroscopic all-inside repair using the Meniscal Viper Repair System is an effective treatment method when it is performed simultaneously with ACL reconstruction.

With the advent of checkpoint inhibitors, it has opened up opportunities for numerous cancer patients. However, as is the case with every treatment, complications need to be weighed. Gastrointestinal adverse effects, such as diarrhea and colitis are well-known complications for checkpoint inhibitors. In severe cases, colitis-induced colonic perforation may occur with an estimation of 1.0% to 1.5% in anti-CTLA-4 antibodies. However, only a handful of cases of such devastating complications have been reported in anti-PD-1 antibodies such as pembrolizumab and nivolumab. We here report a case of intestinal perforation in a patient treated with nivolumab.

BACKGROUND/AIMS: Currently, a new over-the-scope clip (OTSC) system has been introduced. This system has been used for gastrointestinal perforations and fistulas in other countries. The aim of our study is to examine the therapeutic success rate of endoscopic treatment using the OTSC system in Korea. METHODS: This was a multicenter prospective study. A total of seven endoscopists at seven centers performed this procedure. RESULTS: A total of 19 patients were included, with gastrointestinal leakages from anastomosis sites, fistulas, or esophageal perforations due to Boerhaave’s syndrome. Among these, there were three gastrojejunostomy sites, three esophagojejunostomy sites, four esophagogastrostomy sites, one esophagocolonostomy site, one jejuno-jejunal site, two endoscopic full thickness resection site closures, one Boerhaave’s syndrome, two esophago-bronchial fistulas, one gastrocolonic fistula, and one colonopseudocyst fistula. The size of the leakage ranged from 5 to 30 mm. The median procedure time was 16 min. All cases were technically successful. Complete closure of the leak was achieved in 14 of 19 patients using OTSC alone. CONCLUSIONS: The OTSC system is a safe and effective method for the management of gastrointestinal leakage, especially in cases of anastomotic leakage after surgery.

Injuries to the gallbladder are found in about only 2% of patients with blunt abdominal trauma, and isolated gallbladder perforation is even less common. The gallbladder is less accessible to trauma because it is partially embedded in the liver, cushioned by the surrounding omentum and bowel, and shielded by the rib cage. It is usually associated with other visceral injuries, especially the liver. The leakage of bile from a ruptured gallbladder may not immediately produce symptoms of peritonitis, making an early diagnosis difficult, and causes delays to treatment. A 47-year-old man presented to our emergency department complaining of diffuse abdominal pain after a pedestrian traffic accident, but his vital signs were stable. In the laboratory tests, his hemoglobin was normal, but his blood chemistry showed mild jaundice (bilirubin 3.6 mg/dl). An abdominal computed tomogram showed pericholecystic and a right paracolic fluid collection, with a collapsed gallbladder. The patient underwent an operation under a diagnosis of hemoperitoneum, and when the peritoneal cavity was entered, the gallbladder was ruptured at the fundus, and about 500 cc of bile had accumulated in the abdominopelvic cavity. The other visceral organs were non-specific. We report a case of an isolated rupture of the gallbladder, with a review of the associated literature.

Developed proteome-scale ortholog and paralog prediction methods are mainly based on sequence similarity. However, it is known that even the closest BLAST hit often does not mean the closest neighbor. For this reason, we added conserved interaction information to find orthologs. We propose a genome-scale, automated ortholog prediction method, named OrthoInterBlast. The method is based on both sequence and interaction similarity. When we applied this method to fly and yeast, 17% of the ortholog candidates were different compared with the results of Inparanoid. By adding protein-protein interaction information, proteins that have low sequence similarity still can be selected as orthologs, which can not be easily detected by sequence homology alone.

STUDY DESIGN: A case report. OBJECTIVES: To report a rare case of remote cerebellar hemorrhage (RCH) as a complication of spinal surgery. SUMMARY OF LITERATURE REVIEW: Remote cerebellar hemorrhage is rare but lethal as a complication of spinal surgery. Interestingly, dural tears and cerebrospinal fluid (CSF) leakage are reported in all published cases of RCH. MATERIALS AND METHODS: A 67-year-old man had posterior lumbar decompression and posterolateral fusion for spinal stenosis at L4/5/S1. Intraoperatively, the dura was torn and there was a loss of CSF. The dural tear was sutured immediately in a water-tight manner. After surgery, the patient complained of headache and dizziness. On postoperative day 44, brain magnetic resonance imaging (MRI) showed meningeal enhancement suggesting meningitis. On postoperative day 54, brain computed tomography (CT) showed cerebellar edema and hemorrhage, and external ventricular derivation was performed. RESULTS: The patient died. CONCLUSIONS: Special attention should be paid to prevent dural damage during spinal surgery or minimize CSF leakage in the case of dural damage and tears during spinal surgery, and CT and MRI should be promptly performed for symptomatic patients.

Splenic infarction caused by malaria is a rare complication and this is mostly caused by plasmodium falciparum. We report here on a 38 year-old female patient who developed symptomatic splenic infarction that was caused by vivax malaria. She presented with fever and left upper quadrant pain. Computed tomography showed multiple low density areas in the spleen, and the peripheral blood smear revealed plasmodium vivax infestation. We examined for other causes of splenic infarction, but all were negative. This is just the second report of symptomatic splenic infarction that was caused by vivax malaria only. Unlike the previous case, the levels of D-dimer and fibrinogen degradation factor were elevated. This may be related with the hypercoagulable state caused by malaria. Treatment was conservative and the further course was uneventful.
